Penetration moxibustion for postpartum subinvolution of uterus: Two case reports and mechanism analysis: 透灸法成功治疗产后子宫复旧不良:两则病例报告及机制分析

This article introduced the application of penetration moxibustion in successfully treating two cases of postpartum subinvolution of uterus. The main complaint of one case was increasing volume of abnormal vaginal bleeding for five days after delivery. The bleeding stopped after the patient received 7 times treatment of warming needle and penetration moxibustion on Zhōngjí (中极CV3), Guānyuán (关元CV4) and Qìhăi (气海CV6). The other case complained about persistent abdominal pain for 15 days, which was worsening for the recent 2 days. The symptom of abdominal pain was relieved after the penetration moxibustion was applied on CV4, CV6 and Zǐgōng (子宫 EX-CA1) for 5 times for the case. Penetration moxibustion can relieve abdominal pain during the postpartum period, accelerate lochia discharge, and recovery of menstrual and uterine cavity. Àiyè (艾叶 Artemisiae Argyi Folium) was proved to have antibacterial, hemostatic, and analgesic effects. The warming function and radiation features of moxibustion can help to alleviate spasm of the smooth muscle in the uterus and enhance the metabolism of the uterine tissue by expanding microvessels and improving the circulations of both blood and lymph. It can also activate cells in the uterine tissue by increased temperature in order to enhance the decomposition and elimination of pathological wastes, such as inflammation and hematoma. In addition, it can also relieve pelvic pain by inhibiting neuronal excitability.     

Circulating irisin levels are lower in patients with either stable coronary artery disease (CAD) or myocardial infarction (MI) versus healthy controls,whereas follistatin and activin A levels are higher and can discriminate MI from CAD with similar to CK-MB accuracy

BackgroundSeveral myokines are produced by cardiac muscle. We investigated changes in myokine levels at the time of acute myocardial infarction (MI) and following reperfusion in relation to controls.MethodsPatients with MI (MI Group, n = 31) treated with percutaneous coronary intervention (PCI) were compared to patients with stable coronary artery disease (CAD) subjected to scheduled PCI (CAD Group, n = 40) and controls with symptoms mimicking CAD without stenosis in angiography (Control Group, n = 43). The number and degree of stenosis were recorded. Irisin, follistatin, follistatin-like 3, activin A and B, ALT, AST, CK and CK-MB were measured at baseline and 6 or 24 h after the intervention.ResultsMI and CAD patients had lower irisin than controls (p < 0.001). MI patients had higher follistatin, activin A, CK, CK-MB and AST than CAD patients and controls (all p ≤ 0.001). None of the myokines changed following reperfusion. Circulating irisin was associated with the degree of stenosis in all patients (p = 0.05). Irisin was not inferior to CK-MB in predicting MI while folistatin and activin A could discriminate MI from CAD patients with similar to CK-MB accuracy. None of these myokines was altered following PCI in contrast to CK-MB.ConclusionsIrisin levels are lower in MI and CAD implying that their production may depend on myocadial blood supply. Follistatin and activin A are higher in MI than in CAD suggesting increased release due to myocardial necrosis. They can predict MI with accuracy similar to CK-MB and their role in the diagnosis of MI remains to be confirmed by prospective large clinical studies.     

The association between immunoglobulin concentrations and prediabetes prevalence in a large Chinese cohort

AimsPrediabetes has received public attention owing to the increasing prevalence worldwide. Mounting evidence has indicated that inflammation directly contributed to the etiology of glucose metabolism disorders. Although immunoglobulins play a crucial role in immune responses, little research has been done on the link between immunoglobulins and prediabetes in adults. Hence, the aim of the present study was to explore the associations between immunoglobulins levels and prevalence of prediabetes in a general adult population.MethodsA cross-sectional study was conducted among 8856 adults (mean ± standard deviation age: 48.4 ± 10.7 years) in Tianjin, China. The serum immunoglobulins concentrations were measured by the immunonephelometric technique. Prediabetes was diagnosed using the following parameters in accordance with the American Diabetes Association: fasting plasma glucose, postprandial glucose and glycosylated hemoglobin. The associations between concentrations of immunoglobulins and the prevalence of prediabetes were assessed using multiple logistic regression models.ResultsOverall, the prevalence of prediabetes was 37.4% (3311/8856). After controlling for confounders, compared with the lowest quintile, the odds ratios (95% confidence interval) of prediabetes for the highest quintile of immunoglobulins (immunoglobulin G, immunoglobulin E, immunoglobulin M and immunoglobulin A) were as follows: 1.06 (0.91–1.23), 1.31 (1.13–1.52), 0.86 (0.74–1.01), and 1.19 (1.03–1.38) (P for trend were 0.35, < 0.0001, 0.04 and 0.02), respectively.ConclusionsElevated immunoglobulin E and immunoglobulin A levels were independently and positively associated with prediabetes prevalence. There was also a trending association between immunoglobulin M concentrations and prediabetes prevalence. Further studies are necessary to clarify if there is a causal association of immunoglobulins in prediabetes or if they reflect early immunologic disturbances in these patients.     

Curcumin-3,4-Dichloro Phenyl Pyrazole (CDPP) overcomes curcumin's low bioavailability,inhibits adipogenesis and ameliorates dyslipidemia by activating reverse cholesterol transport

BackgroundAdipocyte dysfunction, obesity and associated metabolic disorders are of prime healthcare concern worldwide. Among available medications, natural products and inspired molecules hold 40% space in clinically prescribed medicines. In queue, this study overcomes the drawback of curcumin's low bioavailability with potent anti-adipogenic and anti-dyslipidemic activity.MethodsTo evaluate the role of CDPP on adipocyte differentiation, 3T3-L1 adipocytes were used as an in-vitro model. Flow cytometry was performed for cell cycle analysis. Syrian golden hamsters were used to study pharmacokinetic profile and dyslipidemic activity exhibited by CDPP.ResultCDPP was found to be a potent inhibitor of adipogenesis in-vitro. It blocked mitotic clonal expansion by causing cell cycle arrest. CDPP showed marked improvement in gastrointestinal stability and bioavailability in-vivo as compared to curcumin. Administration of CDPP (100 mg/kg) significantly improved HFD induced dyslipidemic profile in hamsters and activated reverse cholesterol transport machinery.ConclusionCDPP could be used as a potential drug candidate against adipogenesis and dyslipidemia with enhanced gastrointestinal stability and bioavailability.     

Pacifiplex: an ancestry-informative SNP panel centred on Australia and the Pacific region

The analysis of human population variation is an area of considerable interest in the forensic, medical genetics and anthropological fields. Several forensic single nucleotide polymorphism (SNP) assays provide ancestry-informative genotypes in sensitive tests designed to work with limited DNA samples, including a 34-SNP multiplex differentiating African, European and East Asian ancestries. Although assays capable of differentiating Oceanian ancestry at a global scale have become available, this study describes markers compiled specifically for differentiation of Oceanian populations. A sensitive multiplex assay, termed Pacifiplex, was developed and optimized in a small-scale test applicable to forensic analyses. The Pacifiplex assay comprises 29 ancestry-informative marker SNPs (AIM-SNPs) selected to complement the 34-plex test, that in a combined set distinguish Africans, Europeans, East Asians and Oceanians. Nine Pacific region study populations were genotyped with both SNP assays, then compared to four reference population groups from the HGDP-CEPH human diversity panel. STRUCTURE analyses estimated population cluster membership proportions that aligned with the patterns of variation suggested for each study population’s currently inferred demographic histories. Aboriginal Taiwanese and Philippine samples indicated high East Asian ancestry components, Papua New Guinean and Aboriginal Australians samples were predominantly Oceanian, while other populations displayed cluster patterns explained by the distribution of divergence amongst Melanesians, Polynesians and Micronesians. Genotype data from Pacifiplex and 34-plex tests is particularly well suited to analysis of Australian Aboriginal populations and when combined with Y and mitochondrial DNA variation will provide a powerful set of markers for ancestry inference applied to modern Australian demographic profiles. On a broader geographic scale, Pacifiplex adds highly informative data for inferring the ancestry of individuals from Oceanian populations. The sensitivity of Pacifiplex enabled successful genotyping of population samples from 50-year-old serum samples obtained from several Oceanian regions that would otherwise be unlikely to produce useful population data. This indicates tests primarily developed for forensic ancestry analysis also provide an important contribution to studies of populations where useful samples are in limited supply.     

Association of plasma dipeptidyl peptidase-4 activity with non-alcoholic fatty liver disease in nondiabetic Chinese population

ObjectiveThe pathogenesis of non-alcoholic fatty liver disease (NAFLD) is attributed to a “multi-hits hypothesis” involving insulin resistance, oxidative stress and inflammation. Dipeptidyl peptidase-4 (DPP4) was identified as a novel adipokine capable of enhancing the“multi-hits”. Hence, we investigated the association between plasma DPP4 activity and NAFLD in nondiabetic Chinese population.Design and methodsWe performed a cross-sectional study using data from 1105 subjects (36–79 years) in Guilin between 2015 and 2016. Plasma DPP4 activity, homeostatic model assessment of insulin resistance (HOMA-IR), oxidative stress parameters, and inflammatory markers were measured in all participants. NAFLD and its severity were diagnosed by ultrasound after the exclusion of alcohol abuse and other liver diseases.ResultsParticipants in the highest quartile of DPP4 activity had higher HOMA-IR, nitrotyrosine, 8-iso-PGF2a, interleukin-6, CRP, alanine aminotransferase, aspartate aminotransferase and γ-glutamyltransferase compared with those in the lowest quartile (all P < 0.05). Plasma DPP4 activity gradually increased across the groups according to the ultrasonographic severity of steatosis (P < 0.001 for the trend). In the highest DPP4 quartile, NAFLD risk was higher (odds ratio 1.88; 95% CI 1.04–3.37) than in the lowest quartile after adjustment for confounders. The risk for NAFLD increased more with higher levels of DPP4 activity, HOMA-IR, nitrotyrosine, 8-iso-PGF2a, interleukin-6 and CRP.ConclusionsPlasma DPP4 activity is significantly associated with NAFLD. The underlying mechanisms may be partly attributed to the interactions between insulin resistance, oxidative stress, inflammation, and DPP4.
