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.

     

Validation of the state version questionnaire on autonomic regulation (state-aR) for cancer patients

Objectives

Current quality of life inventories used in oncology mainly measure the effects of chemo- or radiotherapy alongside functional and role scales. A new approach is to measure the autonomic state of regulation with the trait-inventory of autonomic regulation (Trait-aR). Loss of Trait-aR has been shown in different medical conditions such as breast cancer (BC) but not in colorectal cancer patients (CRC). In this paper we report the validation of a new state autonomic regulation scale (State-aR) of the last week.

Methods

Study 1 included 114 participants: (41 women/16 men with cancer and 57 age- and gender-matched healthy people) to conduct a reliability-, factor- and validity-analysis. Concurrent and convergent validity was evaluated with Trait-aR, Fatigue-Numeri-cal-Scale, Hospital Anxiety and Depression Scale (HADS-D) and the self-regulation scale, 65 participants were retested. Study 2 completed 42 participants: 17 with BC and 25 with CRC receiving chemotherapy. The State-aR was administered prior, during and after chemotherapy for measuring responsiveness.

Results

The factor analysis loaded to four subscales of State-aR (rest-activity, orthostatic-circulatory, thermosweating and digestive regulation) with a: Cronbach-α r_α = 0.77-0.83 and a test-retest-reliability r_rt = 0.60-0.80. The sum- and sub scales correlated with their concurrent subscales in the Trait-aR (0.48-0.74) and with the sum-scale moderately with all convergent criteria (r = 0.41 --0.44; p < 0.001). During chemotherapy the State-aR-sum and rest-activity-scale decreased significantly compared to the change in the Trait-aR (p < 0.05).

Conclusions

These findings support that the state autonomic regulation scale has satisfactory to good reliability, good validity and acceptable responsiveness in the context of chemotherapy treatment.

     

Development, Reliability and Validity of Traditional Chinese Medicine Health Self-Evaluation Scale (TCM-50)

Objective: To develop a health-evaluating scale from a Chinese medicine(CM) perspective and reflecting CM conception of health. Methods: The Traditional Chinese Medicine Health Self-Evaluation Scale(TCM-50) was developed by verification of dimensions, formation of item pool, verification of scoring methodology, and pilot test of scale and item analysis. Results: TCM-50 composed of 50 items that could be classified into 4 dimensions including physiology and health, psychology and health, nature and health, and society and health. An examination of reliability and validity of TCM-50 yielded Cronbach's α coefficient of 0.927, and half coefficient of r was 0.876. The intraclass correlation coefficient of total score was 0.912. After using SF-36 questionnaire to evaluate the criterion validity, the Pearson r of the score of the two scales from the same participant was 0.740. Conclusions: TCM-50 has good reliability and validity, and can yield similar levels of efficacy as SF-36 in terms of evaluating people's overall health level. As a scale based on CM theory, TCM-50 is suitable for self-measuring the general health of Chinese patients.     

Suppression of Oxidative Stress of Modified Gongjin-Dan (WSY-1075) in Detrusor Underactivity Rat Model Bladder Outlet Induced by Obstruction

Objective

To investigate the anti-oxidative stress and preventive effect of modified Gongjin-dan (WSY-1075) in a detrusor underactivity rat model.

Methods

Rats were randomly allocated to three groups: shamoperated (control), bladder outlet obstruction-induced detrusor underactivity (BOO-DU), and BOO-DU with WSY-1075 (WSY) groups. WSY-1075 was orally administrated to rats 200 mg daily for 2 weeks prior to the operation and 4 weeks after the operation. Bladder outlet obstruction was surgically induced in rats by ligation around the urethra avoiding total obstruction. Cystometrography was conducted on rats in each group for examination of bladders.

Results

Compared with the control group, bladder outlet obstruction led to a significant increase in oxidative stress with consequent changes to molecular composition, and decrease in maximal detrusor pressure (P<0.05). WSY-1075 treatment significantly suppressed oxidative stress and prevented degenerative and dysfunctional changes in bladder, as compared with BOO-DU group (P<0.05).

Conclusion

WSY-1075 had beneficial effect on prevention of BOO-DU.

     

Unravelling the genome: a review of molecular genetic research in schizophrenia

Background

Schizophrenia is a common and complex mental illness that affects approximately 1% of the population worldwide. Despite intensive research over the years, the aetiology and pathogenesis of schizophrenia is poorly understood. However, it has long been recognised that schizophrenia is highly familial suggesting a possible genetic aetiology.

Aim

To review recent molecular genetic research in schizophrenia.

Methods

Medline and Embase search.

Results

Over the past decade, with the completion of the Human Genome Project, molecular genetic research has now identified a number of genes that are very likely to predispose to schizophrenia.

Conclusion

This article discusses the methodologies that have been used to identify schizophrenia susceptibility genes and provides a review of recently identified genes thought to play a role in the pathogenesis of this illness.

     

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.

     

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.

     

Changes in Small Intestinal Motility and Related Hormones by Acupuncture Stimulation at Zusanli (ST 36) in Mice

Objectives

To clarify the effects of acupuncture stimulation at Zusanli (ST 36) on the hormonal changes.

Methods

Eight-week-old male C57BL/6 mice received acupuncture stimulation at acupoint ST 36 or Quchi (LI 11) once a day for 3 or 5 days in the acupuncture-stimulated groups, but not received in the normal group (n=6 in each group). On day 3 or 5, animals were given 0.1 mL of charcoal orally with a bulbed steel needle, 30 min after the last acupuncture stimulation. Ten minutes later, mice were anesthetized, and the intestinal transit and the concentrations of vasoactive intestinal peptide (VIP), motilin, ghrelin and gastrin in the serum were measured.

Results

Compared to no acupuncture stimulation, acupuncture stimulation at ST 36 for 5 days increased the intestinal transit and down-regulated the concentration of VIP and up-regulated the concentrations of motilin, ghrelin and gastrin (P<0.05 or 0.01), whereas acupuncture stimulation at LI 11 did not change them signifificantly (P>0.05).

Conclusion

Acupuncture stimulation at ST 36 for 5 days enhances the small intestinal motility and regulates the secretion of hormones related to small intestinal motility.

     

Wet Cupping Therapy Improves Local Blood Perfusion and Analgesic Effects in Patients with Nerve-Root Type Cervical Spondylosis

Objective

To observe wet cupping therapy (WCT) on local blood perfusion and analgesic effects in patients with nerve-root type cervical spondylosis (NT-CS).

Methods

Fifty-seven NT-CS patients were randomly divided into WCT group and Jiaji acupoint-acupuncture (JA) group according a random number table. WCT group (30 cases) was treated with WCT for 10 min, and JA group (27 cases) was treated with acupuncture for 10 min. The treatment efficacies were evaluated with a Visual Analogue Scale (VAS). Blood perfusion at Dazhui (GV 14) and Jianjing (GB 21) acupoints (affected side) was observed with a laser speckle flowmetry, and its variations before and after treatment in both groups were compared as well.

Results

In both groups, the VAS scores significantly decreased after the intervention (P<0.01), while the blood perfusion at the two acupoints significantly increased after intervention (P<0.05); however, the increasement magnitude caused by WCT was obvious compared with JA (P<0.05).

Conclusions

WCT could improve analgesic effects in patients with NT-CS, which might be related to increasing local blood perfusion of acupunct points.

     

Acupuncture Alters Pro-inflammatory Cytokines in the Plasma of Maternally Separated Rat Pups

Objective: To investigate the potential alleviating effects of acupuncture on maternal separation(MS)-induced changes in plasma pro-inflammatory cytokine levels of rat pups. Methods: On postnatal day 15, rat pups were randomly assigned to 4 groups(n=6 per group) using a random number table: normal, MS, MS with acupuncture stimulation at Shenmen(HT 7) acupoint(MS+HT 7), and MS with acupuncture stimulation at Chengshan(BL 57) acupoint(MS+BL 57) groups. Rat pups in the normal group were housed with their mothers under standard conditions; those in the MS, MS+HT 7 and MS+BL 57 groups were maternally separated and individually maintained. Acupuncture stimulation was performed at HT 7 or BL 57 acupoints once a day for 7 consecutive days. A tail suspension test was performed to measure immobility time of rats and the plasma was collected on postnatal day 21, then levels of corticosterone(CORT), interleukin(IL)-1β, IL-6 and glial cell-derived neurotrophic factor(GDNF) in plasma were measured. Results: Compared with the normal group, the immobility time and the plasma levels of CORT, IL-1β, IL-6 and GDNF in the MS group were significantly increased(P0.05 or P0.01). Compared with the MS group, the immobility time and the plasma levels of CORT, IL-1β, IL-6 and GDNF were significantly reduced in the MS+HT 7 group(P0.05 or P0.01). Moreover, the immobility time and plasma levels of IL-1β and IL-6 in the MS+HT 7 group were significantly lower than those in the MS+BL 57 group(P0.05). Conclusion: Acupuncture stimulation at HT 7 can alleviate the behavioral impairment and changes of the cytokines by MS, indicating that acupuncture can help to relieve MS-induced depression.     

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.

     

Analysis of clinical features of ocular presentation in cranial venous sinus thrombosis

Background

To recognize ocular presentations in cranial venous sinus thrombosis (CVST) which were easy to be misdiagnosis.

Design

Retrospective study.

Methods

Review clinical informations including general informations, general performances, and ocular presentations of 118 inpatients with CVST in the general hospital of chinese people's liberation army during 2005-2009.

Main Outcome Measures

The ocular symptoms as the initial onset presentations or simultaneous phenomenon among different onset type patients were analyzed.

Results

Of all the CVST patients, 21.2% (25/118) presented with ocular symptom as the initial presentation, 30.5% (36/118) presented with ocular symptom as well as the other symptoms, and 48.3% (57/118) presented with non-ocular symptoms as the initial onset. The CVST patients were divided into 3 groups according to the onset type. There was no marked statistical significance among groups. The most common major complaints were blurring and degeneration of acute vision, accounting for 85.9% (61/71) of all abnormal ocular chief complaints. The most common objective sign in eyes was papilloedema, accounting for 48.3% (57/118) in this group of CVST patients. About 22.4% (13/58) showed acute vision deterioration at 1-year follow-up, due to optic atrophy.

Conclusions

As ophthalmologists, we should master the onset characteristics and clinical manifestations of CVST. Early diagnosis and treatment is very important for the prevention of vision deterioration, especially for patients with ocular syndrome as the initial onset syndrome. For isolated agnogenic intracranial hypertension, we should consider the possibility of CVST.

Objective: To investigate the chemical transformation of volatile compounds in sulfur-fumigated Radix Angelicae Sinensis. Methods: A comprehensive two-dimensional gas chromatography(GC×GC) and high-resolution time-of-flight mass spectrometry(HR-TOF/MS) with colorized fuzzy difference(CFD) method was used to investigate the effect of sulfur-fumigation on the volatile components from Radix Angelicae Sinensis. Results: Twenty-five compounds that were found in sun-dried samples disappeared in sulfur-fumigated samples. Seventeen volatile components including two sulfur-containing compounds were newly generated for the first time in volatile oils of sulfur-fumigated Radix Angelicae Sinensis. Conclusion: The strategy can be successfully applied to rapidly and holistically discriminate sun-dried and sulfur-fumigated Radix Angelicae Sinensis. GC×GC-HR-TOF/MS based CFD is a powerful and feasible approach for the global quality evaluation of Radix Angelicae Sinensis as well as other herbal medicines.     

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.     

Reporting Characteristics of Case Reports of Acupuncture Therapy with CARE Guidelines

Objective

To investigate the reporting characteristics of case reports of acupuncture therapy with CAse Report (CARE) guidelines, and to explore the applicability of the guidelines for these case reports.

Methods

Case reports published from January 1, 2011 to December 31, 2013, were identified by searching PubMed and the China Biomedicine Database by using MeSH terms. Screening and data extraction of case reports were conducted by two independent researchers. Assessments based on CARE guidelines and data analysis were conducted by using Excel 2003 and RevMan 5.0.

Results

A total of 61 case reports published in 19 journals were identified, which involved 16 major types of diseases. Fifteen (24.6%) case reports declared no conflict of interests, and 5 (8.2%) reported funding sources. None of these case reports met all items of CARE guidelines, and only 6 subordinate items were fully reported among 50% of the case reports. Subgroup analysis indicated that case reports published in English or those that did not have competing interests had higher reporting quality.

Conclusions

The reporting quality of case reports of acupuncture therapy is rather low. The reason might be a lack of awareness among authors and the poor dissemination of information regarding CARE guidelines in China. More evaluation studies are needed to promote and improve adherence to CARE guidelines. Moreover, an extended version of CARE guidelines should be developed for cases reports of special interventions such as acupuncture or adverse events caused by interventions.

     

Are routine peritoneal fluid cultures during appendicectomy justified?

Background

To determine the impact of obtaining routine peritoneal fluid cultures during appendicectomy, on the treatment and the clinical outcomes.

Methods

The case notes of 137 consecutive patients having appendicectomy, selected from the microbiology database over a period of 1 year were reviewed. The microorganisms in peritoneal cultures, selection of antibiotics and clinical outcomes were recorded. Patients were subdivided into two groups; group I: uncomplicated appendicitis and group II: complicated appendicitis.

Results

The study included 137 patients with a median age of 19 years. Cultures were obtained from 79.5% of patients (group I: 67/84, group II: 42/53). Cultures were positive in 28.3% (19/67) patients in group I and 69% (29/42) in group II. Wound infection (5.6%), prolonged ileus (7.5%) and intra-abdominal abscess (3.7%) were the recorded complications in group II. Antibiotics were modified in 3 out of 109 patients.

Conclusion

Intra-operative peritoneal cultures during appendicectomy do not significantly contribute towards patient management.

     

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.     

Effects of Hedan Tablet(荷丹片)on Lipid Profile,Proprotein Convertase Subtilisin/Kexin Type 9 and High-Density Lipoprotein Subfractions in Patients with Hyperlipidemia:A Primary Study

Objective: To investigate the effects of Hedan Tablet(荷丹片) on serum lipid profile, proprotein convertase subtilisin/kexin type 9(PSCK9) and high-density lipoprotein(HDL) subfractions in patients with hyperlipidemia. Methods: Thirty-seven patients with hyperlipidemia were randomized to treatment with Hedan Tablet 4.38 g/day as Hedan group(18 cases) or placebo(19 cases) as control group for 8 weeks. The lipid profile, PCSK9 and HDL subfractions were determined at day 0 and week 8 in both groups respectively. Results: Hedan treatment for 8 weeks mildly decreased serum low-density lipoprotein cholesterol(LDL-C) levels, while no changes were found in total cholesterol(TC), triglycerides(TG) and PCSK9 concentrations. Furthermore, Hedan treatment increased the concentration of large high-density lipoprotein cholesterol(HDL-C) and the percentage of large HDL subfraction, while decreased the concentration of small HDL-C and the percentage of small HDL subfraction without changing serum HDL-C levels in patients with hyperlipidemia. Conclusion: Hedan treatment of 4.38 g per day for 8 weeks could confer a favorable effects on serum LDL-C concentration as well as HDL subfractions.
