Key Symptoms Selection for Two Major Syndromes Diagnosis of Chinese Medicine in Chronic Hepatitis B

Objective

To identify key symptoms of two major syndromes in chronic hepatitis B (CHB), which can be the clinical evidence for Chinese medicine (CM) doctors to make decisions.

Methods

Standardization scales on diagnosis for CHB in CM were designed including physical symptoms, tongue and pulse appearance. The total of 695 CHB cases with dampness-heat (DH) syndrome or Pi (Spleen) deficiency (SD) syndrome were collected for feature selection and modeling, another 275 CHB patients were collected in different locations for validation. Key symptoms were selected based on modified information gain (IG), and 5 classifiers were applied to assist with models training and validation. Classification accuracy and area under receiver operating characteristic curves (AUC) were evaluated.

Results

(1) Thirteen DH syndrome key symptoms and 13 SD syndrome key symptoms were selected from original 125 symptoms; (2) The key symptoms could achieve similar or better diagnostic accuracy than the original total symptoms; (3) In the validation phase, the key symptoms could identify syndromes effectively, especially in DH syndrome, which average prediction accuracy on 5 classifiers could achieve 0.864 with the average AUC 0.772.

Conclusion

The selected key symptoms could be simple DH and SD syndromes diagnostic elements applied in clinical directly. (Registration N0.: ChiCTR-DCC-10000759)

     

Sublingual Nodules: Diagnostic Markers of Metastatic Breast Cancer

Objective: To evaluate the diagnostic significance of sublingual nodules for metastasis of patients with breast cancer and further to explore the mechanisms of sublingual nodules. Methods: The image data of 117 in-patients with breast cancer in stage Ⅰ–Ⅳ in Tianjin Medical University Cancer Institute and Hospital from December 2009 to September 2011 were assessed retrospectively. All photos of patients' tongue were recorded by the digital camera of uniform type within 1 month after serological examination and regular re-examined by computed tomography(CT), magnetic resonance imaging and positron emission tomography CT. The presence of sublingual nodules was the positive standard. Chi square test and two-independent-sample test were used to determine the diagnostic value between the status of sublingual nodules and Clinico-pathological characteristics. The optimal cut-off of uric acid(UA) level to diagnose sublingual nodules was determined by receiver operating curve(ROC) analysis. Results: Breast cancer patients with sublingual nodules had a higher risk of recurrence and/or metastasis than patients without it(P0.001). Sublingual nodules was significantly correlated with increased serum UA level(P=0.001). The optimal cut-off value of UA level to diagnose sublingual nodules was 290 μmol/L. Furthermore, the elevated serum UA level( 290 μmol/L) was significantly related to breast cancer recurrence and/or metastasis(P0.001). Conclusions: Sublingual nodules were potential diagnostic markers for metastatic breast cancer. The formation of sublingual nodules was associated with elevated level of serum UA.     

Expert Opinions on the Concept of Blood Stasis in China: An Interview Study

Objective

To study various experts’ opinions on the defifinition and diagnosis of blood stasis in China.

Methods

We e-mailed the selected experts to explain the purpose of the study and to invite them to participate and asked them to name a time for the investigator to call them. Eight experts and fifive organizations were interviewed in the research community investigating blood stasis in China.

Results

Six main categories emerged from the interviews: (1) blood stasis concepts; (2) blood stasis-related biomarkers; (3) methods of diagnosing blood stasis; (4) drugs for promoting blood circulation and dissipating stasis; (5) blood stasis-related diseases; and (6) blood stasis-related societies. The consensus among the interviewed experts was that the defifinition of blood stasis is rather complicated and that there is no gold standard marker for detecting blood stasis.

Conclusions

This paper acquired experts’ opinions on the defifinition and diagnosis of blood stasis in order to establish a modern concept of blood stasis. This paper also developed a diagnostic tool and diagnostic indices for blood stasis and identifified biological indices and pathologic mechanisms related to blood stasis, which might be of great reference value in future blood stasis standardization research.

     

Impact Evaluation of CONSORT and STRICTA Guidelines on Reporting Quality for Randomized Controlled Trials of Acupuncture Conducted in China

Objective:To evaluate and compare the reports' qualities of acupuncture randomized controlled trials(RCTs) conducted in China before and after the implementation of two guidelines,i.e.,the Consolidated Standards of Reporting Trials(CONSORT) statement and the Standards for Reporting Interventions in Controlled Trials of Acupuncture(STRICTA).Methods:Proportions of studies that reported CONSORT and STRICTA items were compared for the years before and after implementation of these two guidelines.In addition,the total score of each item's reporting were calculated and reported differences during different date ranges were compared.Results:For CONSORT items(maximum score 8),there was evidence of a slight improvement in reporting between 1994-1995 and 1999-2000 combined(2.5 + 0.6) and 2004-2005 and2009-2010 combined(3.0 ±0.9;difference 0.4,95%confidence interval,0.3 to 0.6,P0.01).For STRICTA items(maximum score 17),there was evidence that a slight improvement in reporting between 1994-1995 and 1999-2000 combined(8.6±2.1) and 2004-2005 and 2009-2010 combined(10.1 ±1.8;difference1.5,95%confidence interval,1.1 to 1.9,P0.01).Conclusion:Quality of reporting for RCTs of acupuncture treatment conducted in China have generally improved since the introduction of the STRICTA and CONSORT guidelines.     

Necrotizing fasciitis: microbiological characteristics and predictors of postoperative outcome

Objective

Necrotizing fasciitis is a life threatening soft-tissue infection with a high morbidity and mortality. Prompt treatment based on extensive surgical debridement and antibiotic therapies are the therapeutic principles.

Methods

The medical records of patients with necrotizing fasciitis (n = 26) from 1996 to 2005 were retrospectively analyzed.

Results

The localization of necrotizing fasciitis was most commonly the trunk (42.3%). Type I polymicrobial infection was the dominating infection. The involvement of anaerobic bacteria was associated with an increase in the number of surgical revisions (p = 0.005). Length of postoperative intensive care unit stay, duration of postoperative ventilation and mortality were significantly increased in the ASA IV-V group. Computed tomography displayed only a limited significance as diagnostic tool for initial diagnosis.

Conclusions

In severe cases the combination of necrotic skin and soft tissue gas facilitates the correct diagnosis, which should than be followed by immediate - and most often - repeated debridement. If anaerobes are isolated an early and aggressive second look is necessary.

Three generations of matrilineal excess of birth defects in Irish families with neural tube defects

Background

Neural tube defects (NTDs) and birth defects overall are more likely to occur among maternal compared to paternal relatives in two generations (uncles/aunts and first cousins) of Irish families where an individual has been born with an NTD.

Aims

The aim of this study was to determine if the matrilineal excess persisted into the third generation.

Methods

First cousins were interviewed about their pregnancy outcomes and their offsprings’ health.

Results

Maternal first cousins once removed (FCOR) were more likely to have birth defects than paternal FCOR: 6.7 versus 3.5% (adjusted odds ratio 1.49, 95% CI 0.57, 3.89). No NTDs occurred. Folic acid supplementation significantly reduced the risk of birth defects (P = 0.04).

Conclusions

This study demonstrates an excess of birth defects among maternal relatives in three consecutive generations of NTD families, and supports the hypothesis that an underlying mechanism links distant maternal relatives in at least some NTD families.

     

Construction-related eye injuries in Irish nationals and non-nationals: attitudes and strategies for prevention

Background

Construction-related ocular injuries are an important cause of vision loss but few studies on the incidence, epidemiology and nature of these injuries exist.

Aims

Due to the perceived increase in occupation-related eye injuries in non-nationals we aimed to investigate the nature of such injuries presenting to a single eye unit over a two-month period.

Methods

One hundred and fifty-five patients presenting to the accident and emergency department with construction related ocular injury were examined.

Results

Of 155 patients, 80 were Irish and 75 non-national, of whom 60, 21.3 and 6.7% were Polish, Lithuanian and Romanian, respectively. Common causative factors included hammering, grinding, drilling and splash injury. Average rate of eyewear protection usage was 35%, with attendance at safety courses highest in Irish nationals. A penetrating eye injury rate of 4.9% overall was observed, all in non-nationals.

Conclusion

Construction related ocular injury is a serious cause of visual loss in non-nationals. Greater adherence to safety regulations and training is required.

     

Effect of Artemisia annua Extract on Treating Active Rheumatoid Arthritis: A Randomized Controlled Trial

Objective

To investigate the effect and safety of the complementary use of the extract of Artemisia annua L. (EAA) on treating active rheumatoid arthritis (RA).

Methods

A randomized controlled clinical trial was performed. All the 159 participates with active RA were randomly assigned to the control group (80 cases) and EAA group (79 cases) using concealed random allocation method. In the control group, patients were medicated with leflflunomide and methotrexate for 48 weeks; and patients in the EAA group were administrated with leflflunomide, methotrexate plus EAA (30 g/d). At the time points of 0, 12, 24 and 48 weeks, the clinical outcome measures, including objective pain score, tenderness score, number of painful joints, number of swollen joints, health assessment questionnaire (HAQ) score for quality of life, levels of serum rheumatoid factor (RF), anti-cyclic citrullinated protein antibodies (CCP-Ab), erythrocyte sedimentation rate (ESR), C reactive protein (CRP), visual analogue score for pain (VAS), and the overall effificacy were detected and recorded.

Results

The objective pain score, number of painful joints and ESR at 12 weeks, tenderness score and HAQ at 24 weeks, and the tenderness score, number of painfull joints, number of swollen joints, HAQ, CRP, RF and CCP-Ab at 48 weeks were signifificantly improved in the EAA group compared with the control group (P<0.01 or P<0.05). At 24 and 48 weeks, the overall effificacy of the EAA group was signifificantly higher than the control group (P<0.01). There were signifificantly higher withdrawal rate of corticosteroids within 12 weeks post-treatment and lower incidence rate of adverse effects in the EAA group compared with the control group (P<0.01 or P<0.05).

Conclusion

EAA plus methotrexate and leflflunomide were more effective and safer than the routine use of methotrexate and leflflunomide in the treatment of active RA.

Objective: To observe the efficacy and safety of Qiaoshao Formula(翘芍方, QSF) on patients with lifelong premature ejaculation(LPE) of Gan(Liver) depression and Shen(Kidney) deficiency syndrome. Methods: A total of 60 LPE patients were randomly divided into treatment(QSF) and control(dapoxetine) groups. The treatment group received QSF twice a day and the control group received dapoxetine 1 to 2 h prior to planned sexual intercourse for 4 weeks. The outcomes included intra-vaginal ejaculation latency time(IELT), premature ejaculation diagnostic tool(PEDT), clinical global impression of change(CGIC), scores of Chinese medicine symptoms(CMSS), sex life satisfaction(SLS) and adverse events(AEs). Results: In the treatment group, the median IELT was 3 min vs. 1.5 min before and after treatment(P0.05). PEDT in the treatment group was reduced to 11.76±1.68 from 15.83±2.30 after treatment(P0.05). Besides, patient's SLS was improved from 1.30±0.05 to 6.30±0.04(P0.05), and spouse's SLS was increased from 1.30±0.08 to 6.10±0.06(P0.05); CMSS was decrease from 14.86±3.02 to 9.62±2.87(P0.05). In addition, no significant AE was observed in both groups. Conclusion: QSF may be effective and safe on LPE patients with Gan depression and Shen deficiency syndrome.     

Diagnostic Indicators for Blood Stasis Syndrome Patients with Gynaecological Diseases

Objective

To investigate the important diagnostic indicators for blood stasis syndrome (BSS) in patients of childbearing age with gynaecological diseases.

Methods

A partial least squared-discriminant analysis (PLS-DA) were applied to BSS symptoms data of patients with gynaecological diseases, and the diagnostic indicators used by doctors of Korean medicine (DKMs) among BSS patients with gynaecological diseases were also investigated.

Results

A total of 103 patients of childbearing age with gynaecological diseases and 40 healthy controls were enrolled. Among the 103 patients, 63 (61.7%) and 40 (38.8%) were diagnosed with BSS and non-BSS, respectively, and BSS patients exhibited a more severe extent of disease. A score plot of PLS-DA showed clearly different patterns among the 3 groups. Based on the variable importance on projection of PLS-DA model, menstrual pains, dark lumps in the menstrual blood, ileocoecal tenderness and resistance, sharp pains, and sublingual varicosities were selected as the top five most important indicators. Moreover, more than 75% of DKMs chose dark lumps in menstrual blood, menstrual pain, and dark menstrual blood as the diagnostic indicators of BSS in patients with gynaecological diseases, and more than 49% of them also considered sharp pains, dark red tongue, sublingual varicosities, and tendency to bruise easily as diagnostic indicators of BSS.

Conclusion

DKMs focused on menstrual symptoms and certain gynaecological symptoms to diagnose BSS patients of childbearing age with female diseases.

     

Preliminary Research on Syndrome Types of Chinese Medicine in Children with Primary Nephrotic Syndrome

Objective

To provide an objective reference for the syndrome types of Chinese medicine (CM) associated with pediatric primary nephrotic syndrome (PNS).

Methods

A cross-sectional study was performed. Data on clinical symptoms, CM syndrome types, biochemical indices, and medications used were collected from 98 children with PNS. Then, the correlation between CM syndromes and biochemical indices, as well as medications used, was analyzed.

Results

The four most common symptoms in children with PNS were brown urine, red tongue, excessive sweating, and swelling of the face and limbs. The syndromes of qi deficiency of Fei (Lung) and Shen (Kidney) (FSQD) and yin deficiency of Gan (Liver) and Shen (GSYD) were the most common main CM syndrome types. FSQD syndrome score correlated significantly with the total cholesterol level, urine protein/creatinine ratio, and urine IgG and albumin levels (P<0.01 or P<0.05). The use of maintenance glucocorticoids combined with immunosuppressive agents correlated with FSQD syndrome, and the use of maintenance glucocorticoids alone correlated with GSYD syndrome (P<0.05).

Conclusion

Two of the most common CM syndrome types were FSQD and GSYD syndromes. FSQD syndrome may be caused by some factors related to lipid levels, protein loss, and the use of immunosuppressive agents. The use of maintenance glucocorticoids may cause GSYD syndrome

     

Prognostic factors in patients with diffuse type gastric cancer (linitis plastica) after operative treatment

Objective

Treatment options for patients with diffuse type gastric cancer (linitis plastica) are discussed controversial. It is sometimes discussed that these patients should be treated primarily in palliative intention conservative without resection.

Methods

In a single-center analysis, we investigated 120 patients with diffuse type gastric cancer. All patients underwent a total gastrectomy, 45 patients even a multivisceral resection because of infiltrating growth, or metastases. Serum tumor marker CEA, CA 72-4, and CA 19-9 were recorded in all patients before surgery. An immunocytochemical detection of free peritoneal tumor cells (FPTC) using Ber-EP4 antibody was correlated with tumor stage and survival. Median follow-up time was 38 months.

Results

Complete resection rate was 31% (n = 37). 61% (n = 73) of all patients had already distant metastases at the time of surgery, 80% of them peritoneal carcinomatosis. Median survival for the whole group was 8 months, after complete resection 17 months. Lavage cytology, distant metastases, resection rate, and CA19-9 levels had significant influence on survival.

Conclusion

A significant survival advantage for patients with diffuse type gastric cancer can only be achived after complete resection. We could define a subset of patients with an extremely poor prognosis even after surgical resection. Meticulous preoperative staging, including a diagnostic laparoscopy to exclude peritoneal carcinomatosis and free peritoneal tumor cells before resection should be mandatory in these patients.

     

Acupuncture Treatment Modulates the Resting-State Functional Connectivity of Brain Regions in Migraine Patients without Aura

Objective: To investigate the modulatory effect of acupuncture treatment on the resting-state functional connectivity of brain regions in migraine without aura(MWo A) patients. Methods: Twelve MWo A patients were treated with standard acupuncture treatment for 4 weeks. All MWo A patients received resting-state functional magnetic resonance imaging(f MRI) scanning before and after acupuncture treatment. Another 12 normal subjects matched in age and gender were recruited to serve as healthy controls. The changes of restingstate functional connectivity in MWo A patients before and after the acupuncture treatment and those with the healthy controls were compared. Results: Before acupuncture treatment, the MWo A patients had significantly decreased functional connectivity in certain brain regions within the frontal and temporal lobe when compared with the healthy controls. After acupuncture treatment, brain regions showing decreased functional connectivity revealed significant reduction in MWo A patients compared with before acupuncture treatment. Conclusions: Acupuncture treatment could increase the functional connectivity of brain regions in the intrinsic decreased brain networks in MWo A patients. The results provided further insights into the interpretation of neural mechanisms of acupuncture treatment for migraine.     

Pure Total Flavonoids from Citrus paradisi Macfad Induce Leukemia Cell Apoptosis In Vitro

Objective

To investigate the potential effect of pure total flavonoids from Citrus paradisi Macfad peel (PTFC) on the proliferation of human myeloid leukemia cells Kasumi-1, HL-60 and K562, and the underlying mechanisms.

Methods

PTFC was extracted from Citrus paradisi Macfad peel and was identified by high performance liquid chromatography. The effect of PTFC on the proliferation and apoptosis of leukemia cells were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, fluorescent microscopy and flow cytometry, respectively. The effect of PTFC on the expression levels of apoptosis-related regulators was determined by Western blot assay.

Results

Treatment with PTFC inhibited leukemia cell proliferation in a dose- and time-dependent manner and triggered Kasumi-1 cell apoptosis. Treatment with PTFC significantly increased the levels of activated poly adenosine diphosphate-ribosepolymerase and caspase-3/-9, but reduced the levels of Mcl-1 expression in Kasumi-1 cells. However, PTFC did not obviously induce HL-60 cell apoptosis.

Conclusion

PTFC inhibited leukemia cell proliferation and induced their apoptosis by modulating apoptosisrelated regulator expression in leukemia cells in vitro.

     

Clinical and Psychometric Validation of the Quality of Life Assessment System for Advanced Gastric Cancer Based on Traditional Chinese Medicine

Objective

To establish questionnaire scaling and reliability and examine the clinical and psychometric validity of the quality of life assessment based on Traditional Chinese Medicine for advanced gastric cancer (QLASTCM-Ga).

Methods

The QLASTCM-Ga was developed based on programmed decision procedures with multiple nominal and focus group discussions, in-depth interview, pretesting and quantitative statistical procedures. The questionnaire was administered to 240 patients diagnosed with advanced gastric cancer before and after treatment. Structured group methods were employed to establish a general and a specifific module respectively. The psychometric properties of the scale were evaluated with respect to validity, reliability and responsiveness.

Results

The three identified scales of the QLASTCM-Ga and the total score demonstrated good psychometric properties. Test-retest reliability of the total scale and all domains ranged from 0.90 to 0.94, and internal consistency ranged from 0.86 to 0.93. Correlation and factor analysis demonstrated good construct validity. Signifificant difference in the subscales and the total score were found among groups differing in traditional Chinese medicine syndrome, supporting the clinical sensitivity of the QLASTCM-Ga. Statistically signifificant changes were found for each scale and the total score. Responsiveness was also good.

Conclusions

The QLASTCM-Ga demonstrates good psychometric and clinical validity to assess quality of life in patients with advanced gastric cancer undergoing traditional Chinese medicine therapy. This study is an important fifirst step for future research in this area.

     

Text Mining of Rheumatoid Arthritis and Diabetes Mellitus to Understand the Mechanisms of Chinese Medicine in Different Diseases with Same Treatment

Objective

To identify the commonalities between rheumatoid arthritis (RA) and diabetes mellitus (DM) to understand the mechanisms of Chinese medicine (CM) in different diseases with the same treatment.

Methods

A text mining approach was adopted to analyze the commonalities between RA and DM according to CM and biological elements. The major commonalities were subsequently verified in RA and DM rat models, in which herbal formula for the treatment of both RA and DM identified via text mining was used as the intervention.

Results

Similarities were identified between RA and DM regarding the CM approach used for diagnosis and treatment, as well as the networks of biological activities affected by each disease, including the involvement of adhesion molecules, oxidative stress, cytokines, T-lymphocytes, apoptosis, and inflammation. The Ramulus Cinnamomi-Radix Paeoniae Alba-Rhizoma Anemarrhenae is an herbal combination used to treat RA and DM. This formula demonstrated similar effects on oxidative stress and inflammation in rats with collagen-induced arthritis, which supports the text mining results regarding the commonalities between RA and DM.

Conclusion

Commonalities between the biological activities involved in RA and DM were identified through text mining, and both RA and DM might be responsive to the same intervention at a specific stage.

     

Therapeutic Effect of Chang'an Ⅰ Recipe (肠安Ⅰ 号方) on Irritable Bowel Syndrome with Diarrhea: A Multicenter Randomized Double-Blind Placebo-Controlled Clinical Trial

Objective: To evaluate the efficacy and safety of Chinese medicine (CM) decoction Chang''an Ⅰ Recipe (肠安Ⅰ 号方) in the treatment of irritable bowel syndrome with diarrhea (IBS-D). Method: A multicenter, randomized, double-blind, placebo-controlled clinical trial was designed. Based on the order of inclusion, the IBS-D patients were randomly assigned to the treatment group or the placebo control group, administrated with Chang''an Ⅰ Recipe or placebo, 150 mL/bag, 3 times daily, for 8 weeks. The primary indices of efficacy included the effective rates of IBS symptom severity score (IBS-SSS) and the differences in adequate relief(AR) responder; the secondary indexes of efficacy included the changes in scores of the IBS Quality of Life (IBS-QOL) and Hospital Anxiety and Depression (HAD) scales. The safety indices included adverse events and related laboratory tests. Results: A total of 216 patients were included, with 109 in the treatment group and 107 in the control group, and finally 206 were included in the full analysis set (FAS), 191 were included in the per protocol set (PPS). In FAS, the total effective rate was 67.6% and 40.2% for the treatment and control groups, respectively, with 95% confidence interval (CI) for difference in the effective rates between the two groups of 14.4%–40.2%; while in PPS, the total effective rate was 71.3% and 41.2% for the treatment and control groups, respectively (95% CI 16.6%–43.4%). The consistent conclusions of FAS and PPS showed a better efficacy in the treatment group. Both FAS and PPS showed higher AR responder in the treatment group (FAS: 59.6% vs. 35.5%; PPS: 62.8% vs. 38.1%). As for IBS-QOL, the total score and scores in various dimensions of IBS-QOL were not significantly different between the two groups (P>0.05). Both anxiety and depression scales of HAD were not significantly different between the two groups (P>0.05). No adverse events or laboratory abnormalities were found to be obviously related to the tested drugs or clinically significant. Conclusion: Chang''an Ⅰ Recipe was more effective than placebo in the treatment of IBS-D, with no obvious adverse reactions. (No.ChiCTR-TRC-09000328)     

Electroacupuncture Stimulation of Language-Implicated Acupoint Tongli (HT 5) in Healthy Subjects: An fMRI Evaluation Study

Objective

To explore brain activations associated with electroacupuncture simulation at Tongli (HT 5) and its comparison with brain activations during picture-naming task.

Methods

Twenty healthy subjects were enrolled in this study. Half of them received electroacupuncture stimulation at HT 5 (ACUP group) and the other half of them received stimulation at a nonmeridian sham acupoint (SHAM group). All subjects performed picture-naming task. Each subject finished two runs of functional magnetic resonance imaging examinations in one session and picture-naming task was performed before electroacupuncture stimulation. Subjective brain activations were obtained using generalized linear model and inter-group analyses were performed after that.

Results

The electroacupuncture stimulation at HT 5 induced significant brain activations in both the anterior and posterior language regions, including the left inferior frontal gyrus, which was in consistent with activations induced during picture-naming task. Group analysis showed a tendency of increased activation of ACUP group in left inferior frontal gyrus compared with SHAM group (P<0.05 FDR corrected).

Conclusions

Electroacupuncture treatment at the acupoint HT 5 has modulation effect on typical language-implicated brain regions in healthy subjects, which provides supporting evidence for beneficial effects of needling at HT 5 for recovery of language function in aphasia.
