Traditional Chinese medicine (TCM) usually views polycystic ovary syndrome (PCOS) as a menstrual disease or infertility disease. Reproductive dysfunction in PCOS is characterized by ovarian androgen excess and disturbance of follicular development, and its main clinical manifestations include delayed menstruation, scant menstruation, amenorrhea or infertility. Insulin resistance is a key pathological mechanism of PCOS. "Tiangui" (kidney essence) as a sex-stimulating essence in female in TCM theory, is essential to the menstruation and pregnancy of women. The disturbance of Tiangui (including time, status and rhythm) would result in female reproductive problems. Current studies of Tiangui indicate that ovary is the target organ of PCOS treatment, and its functional characteristics are consistent with the properties of Tiangui in time frame, state form and rhythm cycle. It is then concluded that ovarian dysfunction in PCOS can be expressed as disorder of Tiangui.

Objective To liver surgical site infection related influencing factors were discussed.Methods Retrospective analysis the clinical data of A total of 1 187 patients with liver and gallbladder surgery,using SPSS12.0 software for statistical analysis of data.Results A total of 1 187 cases of liver and gallbladder surgery patients and 63 cases of surgical site infection occurred,the in-fection rate of 5.31%,including incision shallow tissue 51 cases,8 incision deep tissue,organ lacuna in 4 cases,accounted for 80.95%,12.70% and 6.35% respectively.Isolated pathogenic bacteria distribution and composition ratios were as follow,15 strains of gram-negative bacteria(55.56%),12 gram positive bacteria strains(44.44%),including gram-negative bacteria in e.coli, gram-positive bacterium with staphylococcus aureus detection most(25.93% and 14.81% respectively),not isolated fungus;Age, presence of diabetes mellitus,drainage time,postoperative complications,operation time and open operation for independent risk fac-tors for surgical site infection (P <0.05).Conclusion Liver and gallbladder surgery in patients with surgical site infection is asso-ciated with a variety of factors,should strengthen the preoperative patients with postoperative condition evaluation,improve the lev-el of operation at the same time,thereby reducing surgical site infection.

In order to assess the feasibility of subcutaneous administration of Triptorelin with 6-week intervals for the suppression of pituitary-gonadal axis and changes of clinical signs in girls with idiopathic central precocious puberty (ICPP), 46 girls with ICPP were treated with GnRHa. Triptorelin (Decapeptyl, 3.75 mg) was administered subcutaneously (SC) at 6-weeks intervals or intramuscularly (IM) at 4-weeks intervals randomly for more than 12 months consecutively. During GnRHa therapy, clinical parameters and laboratory data, including height, weight, pubertal stage, bone age, uterine volume and ovarian size, serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH) and estradiol (E2), were monitored and analyzed. It was found that both treatment regimes led to regression of precocious puberty and reversal of secondary sexual characteristics. Breast developments regressed. Uterine volume was decreased after treatment, but there was no statistically significant difference. Mean ovarian volume did not change significantly during treatment. The height velocity was decreased significantly from 6.3+/-1.4 cm/year to 5.8+/-1.2 cm/year in group SC and 6.7+/-1.3 cm/year to 5.4+/-1.0 cm/year in group IM, respectively. The rate of bone maturation was reduced significantly during treatment. The ratio of deltaBA/deltaCA was 1.2+/-0.2 or 1.3+/-0.3 at the onset of therapy and decreased significantly after the treatment to 0.7+/-0.2 or 0.9+/-0.1, respectively. The predicted adult height was increased significantly and progressively during therapy. The levels of serum LH, FSH and E2 returned to the prepubertal condition. No significant side effects of therapy were noted. The most common side effect during SC treatment was that a non-irritating, 1 cm in diameter mass was palpated at the site of subcutaneous injection in the abdominal wall of patients, which disappeared after 6-12 weeks. Two girls had minimal withdrawal vaginal bleeding episodes after the first injection. It was concluded that both IM and SC triptorelin administrations were clinically effective. They induce profound suppression of hypothalamic-pituitary-gonadal axis while stabilizing height velocity, slowing bone maturation and increasing predicted adult height. These results suggest that subcutaneous injection of triptorelin in 6-weeks intervals at a dosage of 3.75 mg be a safe and acceptable regimen for ICPP

Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases. However, due to its complex pathogenesis, there are no officially approved drugs for NAFLD treatment currently. Therefore, it is extremely urgent to find safe and effective anti-NAFLD drugs. Nowadays, lipid-lowering drugs are the main option for NAFLD therapy, but the clinical efficacy of chemical drugs is also very limited, as well as the frequent side effects or adverse reactions. Traditional Chinese medicine (TCM) has attracted more and more attention in the treatment of NAFLD due to its unique advantages through multiple targets and pathways with few side effects. In recent years, numerous studies have demonstrated that the imbalance of gut microbiota plays an important role in the occurrence and development of NAFLD. This review systematically summarizes the experimental and clinical evidences of TCM active compounds and TCM prescription involved in the regulation of intestinal flora in the treatment of NAFLD in recent years, so as to provide a reference for further exploring the pathogenesis of NAFLD and exploring TCM treatment methods.

Background and purpose:Although the third-generation chemotherapeutic agents combined with platinum have shown good effect on non-small-cell lung cancer(NSCLC),whether the regimen is the best for elderly patients with NSCLC still is controversial.The aim of his study was to investigate the efficacy of Shenfu injection combined with Vinorelbine on the improvement of quality of life(QOL)in elderly NSCLC patients.Methods:A randomized single blind trial method was used.46 patients with stageⅢb-Ⅳof NSCLC were randomly divided into research group and control group.In the research group,the patients were treated with 50 ml of Shenfu injection from day 1 to 14,combined with Vinorelbine(NVB)25 mg/m~2 on day 1 and 8.In the control group,the patients were only treated with NVB 25 mg/m~2 on day 1 and 8.After two cycle's of treatment,QOL,efficacy and toxicity were observed. Results:The QOL was enhanced in both research group and control;however,the difference of KPS after treatment in the research group was markedly higher than in the control(14?10 vs.8?10,t=2.116,P=0.04),improvement rate of QOL was better than in the control(76.2% vs.45.0 %,x~2=4.188,P=0.041),treatment related toxicity in the research group was also markedly lower than that in the control(x~2=3.866,P=0.049),but the difference of efficacy between the two groups was not significant(14.3% vs.15.0%,x~2=0.161,P=0.688).Conclusions:ShenFu injection combined with Vinorelbine could enhance QOL in elderly NSCLC patients.

Background Researches documented that retinal nerve fiber layer thickness (RNFLT) in unaffected carriers of Leber hereditary optic neuropathy (LHON) becomes thickened in different quadrants to different degrees.But the change of their macular thickness is still unclear.Objective This study was to clarify RNFLT and macular thickness by optical coherence tomography (OCT) in unaffected female carriers of LHON families.Methods Five female LHON patients (5 eyes) from 5 LHON families,eighteen unaffected female carriers (18eyes) from 18 LHON families and twenty-five age-matched healthy female controls (25 eyes) were included in this study.The patients and genetic carriers were diagnosed in PLA General Hospital from 2011 September to 2012 October.Regular ocular examination were performed followed by OCT measurement of retinas.The Optic Disc Cube 200×200 and Macular Cube 200×200 protocols were used during the OCT measurement.Average (360°) RNFLT,RNFLT at four quadrantic sections,cube average macular thickness and macular thickness of nine Early Treatment Diabetic Retinopathy Study (ETDRS) sub-areas were compared among the LHON genetic carriers,LHON patients and normal controls.Results Compared to the normal control group,significant reduced values were seen in temporal,superior,nasal and inferior side of sub-area macular thickness in the LHON female carriers (P=0.022,0.046,0.024,0.008).In addition,but no significant differences were found in cube average thickness,central subarea macular thickness,temporal,superior,nasal and inferior side of lateral sub-area macular thickness,average RNFLT,and temporal,superior,nasal and inferior quadrant RNFLT between the LHON female carriers and normal controls (P=0.102,0.051,0.238,0.663,0.1 10,0.104,0.419,0.371,0.158,0.063,0.563).Compared to the unaffected female carrier group,female patients showed significant reductions in cube average macular thickness,temporal,superior,nasal and inferior side of sub-area macular thickness,temporal,superior,nasal and inferior side of lateral sub-area mac ular thickness,average R NFLT and temporal,superior,and inferior quadrant RNFLT (P =0.000,0.000,0.000,0.007,0.002,0.002,0.000,0.000,0.040,0.000,0.016,0.000,0.000) except for the central subarea macular thickness and nasal quadrant RNFLT (P=0.388,0.580).Conclusions Unaffected LHON female carriers show a normal peripapillary RNFLT,but the macular thickness at medial sub-area is thinner.This first report offers an information of macular structure change in unaffected LHON female carriers,which suggest that macular damage appears prior to RNFLT change.

OBJECTIVE:To screen antioxidant active components of Schisandra chinensis. METHODS:The orthogonal test was adopted to optimize extraction technology using DPPH free radical scavenging activity(IC50)as index and ethanol volume frac-tion,material-liquid ratio and extraction time as factors,and the verification test were made. The fractions(SC-0,SC-10,SC-30, SC-50,SC-70,SC-95) were made by extracting and purifying S. chinensis with macroporous resin with water and 10%,30%, 50%,70%and 95%ethanol. With IC50 and total antioxidant capacity(determined by ABTS method)as indexes(vitamin C as pos-itive control),the antioxidant active components of S. chinensis were optimized. The contents of 5 kinds of lignan in different posi-tions of S. chinensis were determined by HPLC. RESULTS:The optimal extraction condition of S. chinensis was as follows as 60% ethanol,material-liquid ratio of 1∶14,extracting for 2.0 h. The average IC50 of DPPH free radical scavenging activity was 23.81 mg/ml(RSD=0.52%,n=3)in verification test. SC-0 did not have antioxidant abilities. DPPH free radical scavenging activi-ty of those components (ie. the IC50 value from low to high) were in the following order of positive control>SC-50>SC-30>SC-95>SC-70>SC-10;total antioxidant ability of them were in the following order of SC-50>positive control>SC-30>SC-70>SC-95>SC-10;the contents of 5 types of lignan in different components were in the following order of SC-70>SC-50>SC-95>SC-30. CONCLUSIONS:The antioxidant active component of S. chinensis is 50%ethanol eluate.

BACKGROUND: With the development of biotechnology, the electrophysiology of repairing heart tissues of myocardial infarction or myocardial hypertrophy by using bone marrow mesenchymal stem cell has become a hot spot. OBJECTIVE: To overview the research progress of cardiac electrophysiological characteristics after transplantation of induced differentiation of bone marrow mesenchymal stem cells into cardiomyocytes. METHODS: The databases of PubMed, Springer Link, Science Direct and CNKI were retrieved for papers published from January 2000 to October 2010 with the key words of bone marrow mesenchymal stem cells, cardiac/heart, electrophysiology/electrophysiological characteristics. The relevant articles concerning cardiac electrophysiological characteristics of induce differentiation and transplantation of bone marrow stem cells were collected. RESULTS AND CONCLUSION: Totally 208 papers have been searched. Preliminary screening by reading abstracts to exclude 162 papers that study purpose do not coincident with this review either contents duplicated, and internalized 46 papers at last. Bone marrow mesenchymal stem cells after induced differentiation and transplantation could improve heart function of animal experimental model and myocardial infarction or myocardial hypertrophy patients. Although the cardiomyocyte-like cells from bone marrow mesenchymal stem cells could help to improve heart function, the cardiac electrophysiological characteristics may be influenced by them.
