[Objective] To observe the therapeutic effect of wind - dispelling, blood - activating and stasis - removing Chinese herbs combined with autoepidermic grafting for vitiligo. [Methods] Forty cases of vitiligo were randomized into two groups: 28 cases in Group A were treated with Chinese herbs combined with autoepidermic grafting (235 grafts in all) and 12 in Group B with autoepidermic grafting (118 grafts in all) alone. [Results] In Group A, 1 case was cured, 13 were markedly effective, 10 effective and 4 ineffective and 0, 3, 3, and 6 in Group B respectively. The therapeutic effect in Group A was superior to that in Group B (P = 0.034). [Conclusion] Chinese herbs combined with autoepidermic grafting has a better effect than autoepidermic grafting alone for vitiligo.

[Objective] To observe the therapeutic effect of oral use of heat-clearing, damp-removing and toxicity-clearing herbal medicine combined with ultrasonic wave and herbal medicine mask treatment in treating acne simplex (AS). [Methods] Two hundred and ten cases of AS were randomized into groups A and B. Group A ( n=113) was treated with modified Yinchenhao Decoction and Qingfei Decoction for oral use and added with ultrasonic wave and mask prepared with herbal medicine including Borneolum Syntheticum, Flos Lonicerae, Radix Scutellariae, Radix Salviae Miltiorrhizae, Fructus Forsythiae; group B ( n=97) was treated with metronidazole 0.2 g, tid, and vitamin Bg 20mg, tid, as well as erythromycin ointment for external application. After a 4-week treatment, the therapeutic effect was compared. [Results] The total effective rale was 80.6% in group A and 41.3% in group B, and the markedly effective rate was 50.5% in group A and 28.9% in group B, the difference being significant (P

Objective To establish an animal model of PCOS and to detect the DNA methylation states of LHR, INSR and AR genes. Methods 24-days-old female Sprague-Dawley (SD) rats were randomly divided into two groups. The rats in the experimental group were given subcutaneous implanting of levonorgestrel silica gel staff and injected 1.5 IU hCG twice daily for 9 days from the 4th day. The rats in the control group were injected with normal saline at the same time. Ovarian morphologic changes, sex hormone levels, fasting serum insulin and glucose were detected. The LHR, INSR and AR genes' DNA methylation patterns were checked by methylation specific PCR in modeling group and control group. Results The ovarian weight and volume in modeling group were higher than those in control group. The ovaries in modeling group showed multiple follicular cysts, and the number of theca cells and interstitial cells increased. Less developed follicles and corpus lutea were seem. The serum level of progesterone, testosterone, luteinizing hormone, fasting insulin and glucose were significantly higher in experimental group than those in control group, so as the LH/FSH ratio and HOMA index. No methylation of LHR and AR genes were found in both groups. The methylation frequency of INSR gene (76.7%) was significantly higher in modeling group than that in control group (P<0. 001). Conclusion The depression of INSR gene's transcriptional induced by DNA methylation is important in the development of insulin resistance in PCOS.

To investigate the impact of maternal hepatitis B virus (HBV) carrier state on twin pregnancy outcomes. Methods From January 2004 to December 2012, 569 women with twin pregnancy were hospitalized in Nanjing Drum Tower Hospital. Thirty-two women positive for hepatitis B surface antigen (HBsAg)(negative for hepatitis B e antigen, with normal liver function before conception)were included in the HBsAg-positive group and the other 537 women were included in the HBsAg-negative group. The pregnancy outcomes of the two groups were compared by t test and Chi-square test. The risk factors for neonatal birth weight were analyzed by multivariate regression analysis. Results Compared with the HBsAg-negative group, the HBsAg-positive women had a higher incidence of abnormal liver function (alanine aminotransferase≥50 U/L) [18.8% (6/32) vs 5.8% (31/537), χ2=6.367, P=0.012]. The incidence of gestational diabetes mellitus was 21.9% (7/32) in the HBsAg-positive group, which was higher than in the HBsAg-negative group [11.6% (62/537)], although the difference was not significant (χ2=2.132, P=0.144). The incidences of intrahepatic cholestasis of pregnancy,hypertensive disorders complicating pregnancy, premature rupture of membranes, placenta previa, fetal distress, postpartum hemorrhage, preterm birth, caesarean section, umbilical cord around the neck, meconium-staining amniotic fluid and neonatal asphyxia were no statistical difference between two groups (all P<0.05, respectively). Multivariate regression analysis showed that gestational diabetes mellitus (β=67.869, 95%CI: 0.494-135.244, P=0.048), maternal age (β=6.592, 95%CI: 2.020-11.880, P=0.006) and gestational age (β=164.069, 95%CI:154.426-173.712, P<0.01) were risk factors for neonatal birth weight, but not the maternal HBsAg-positive status (β=78.864, 95%CI: -16.950-174.678, P=0.107). Conclusion Twin pregnancy and HBV carrier state increase the risk of abnormal liver function, but not other adverse pregnancy outcomes and newborn diseases.

ObjectivesTo evaluate the effect of combination of liraglutide,a glucagon-like peptide-1 analogue and pioglitazone,an insulin sensitizer,on diabetic db/db mice.MethodsThirty-five 8-week old male db/db mice were divided into control group (n = 8 ),pioglitazone group (n =9 ),liraglutide group (n =9) and combined therapeutic group (n =9),which was given normal saline 0.1 ml,2/d,pioglitazone 24 mg· kg-1 · d-1 (feed contained 0.02％ pioglitazone) + normal saline 0.1 ml,2/d,liraglutide 300 mg/kg,2/d,and pioglitazone 20 mg · kg-1 · d -1 ( feed contained 0.02％ pioglitazone) +liraglutide 300 mg/kg,2/d,respectively.Liraglutide were given at 8:00 and 16:00 via subcutaneous injection after having been diluted with sterilized normal saline.Effect on glucose,lipid metabolism and islet β-cell preservation were assessed after 4 weeks.Oneway ANOVA was adopted for statistical analysis.Results Combination therapy displayed promising anti-hyperglycemic[glycosylated hemoglobin Alc: (4.5 ± 0.6)％vs.(7.3 ±0.4)％,P ＜ 0.001].Glucose tolerance were improved assessed by area under curve(AUC) of glucose by intraperitoneal glucose tolerance test (IPGTT)[(1814 ±91 ) mmol · min · L-1 vs.(4042 ±183) mmol · min · L-1,P ＜0.001];insulin release response to glucose were also preserved as AUC of insulin by IPGTT was higher[( 1639 ±372) μg · min · L-1 vs.(834 ±201 )μg · min · L-1].Combination therapy also reduced circulated free fatty acids and TG[( 202.0 ± 20.4 ) μmol/L vs.( 272.5 ± 21.7 )μmol/L,(0.81 ± 0.28) mmol/L vs.( 1.35 ± 0.21 ) mmol/L],and increased plasma adiponectin [(16.7±2.0)mg/L vs.(10.2±1.8)mg/L].All P value ＜0.05.Islet immunohistochemistry showed that combination therapy significantly increased insulin positive area were[( 59.5 ± 1.5 ) ％ vs.( 22.4 ±1.5) ％]and ratio of Brdu positive β-cells was three folds than vehicle-treated mice[( 2.4 ± 0.5 ) ％ vs.(0.8 ±0.3)％],both greater than each single treatment.Combined therapy significantly improved islet β cell/α cell distribution,which led to islet recovery.ConclusionsCombined therapy improves glucose and lipid metabolism,preserves islet β-cell function and stimulates β-cell proliferation,greater than either liraglutide or pioglitazone treatment alone.

Objective To evaluate the feasibility of using pure laparoscopic radical nephrectomy and thrombectomy to treat renal tumor with renal vein and vena caval thrombus. Methods Two ca-ses o{ right renal tumor with renal vein and vena caval thrombus were reported. Contrast-enchanced CT showed renal tumor extended into renal vein and vena cava in 1 case, and filling defect was found in right renal vein and extended to vena cava in the other. Both patients received pure laparoscopic ra-dical nephrectomy and thrombectomy through retroperitoneal approach. Four trocars were placed du-ring the operation, and the renal artery was dissected before the vena cava was mobilized circumferen-tially above and below the renal vein, a faparoscopic vessel blockage clamp was used to partly occlude the vena cava containing the thrombus. The vena cava was repaired after the intact tumor thrombus was extracted. Results The tumor thrombus extended 0.3 cm and 1.0 cm above the renal vein, re-spectively. Both patients were discharged 5 d after operation. Pathological examinations showed that tumors were epithelioid renal angiomyolipoma and grade Ⅰ-Ⅱ clear cell carcinoma separately. Both patients were free of local recurrence and metastasis 5 months after operation. Conclusion Pure la- paroscopic radical nephrectomy and thrombectomy for renal tumor with vena caval and renal vein thrombus is feasible in carefully selected patients.

Objective To explore the feasibility for the tissue dispersion quantitative analysis software of ultrasonic strain elastography in diagnosing benign or malignant of thyroid lesions.Methods Eighty-two patients with 98 lesions were examined by ultrasonic strain elastography.There were 11 parameters of elastography imaging obtained by the tissue dispersion quantitative analysis software,including average relative strain value(MEAN),standard deviation of relative strain value(SD),area ratio of low-strain region (AREA％),complexity(COMP),kurtosis(KURT),skewness (SKEW),contrast (CONT),entropy(ENT),inverse different moment (IDM),angular second moment (ASM),correlation (CORR).The receiver operating characteristic (ROC) curve was constructed if there were statistically significant differences between benign and malignant lesions,and the areas under the ROC curve were got.Results All parameters except CORR had statistically significant between the groups of benign and malignant thyroid lesions (P ＜0.05).The AREA％ and IDM were the best valuable parameters,the areas under the curve(AUC) of which were 0.965 and 0.908,respectively.Their cut-off point were 81.96％ and 0.42,the sensitivity and specificitywere 98.4％ and 89.2％,91.8％ and 86.5％,respectively.Conclusions The tissue dispersion quantitative analysis software is helpful in the evaluation of benign ormalignant of thyroid lesions,parameters of AREA％ and IDM has the highest relationship with pathology and good diagnostic value.

Objective To explore the expression levels of immune-related microRNA-146b (miR-146b),microRNA-155 (miR-155) and microRNA-30b(miR-30b) in human breast milk and its relationship with maternal and infant's health.Methods One hundred and thirty-four mothers and their infants from obstetrical department were recruited in the study after delivery.The subjects were divided into 2 groups,breast feeding group(n =86) and formula-feeding group(n =48),and were followed up 3 months after delivery.Breast milk samples were collected at 2-5 days after delivery(colostrum) and 3 months after delivery(mature milk).The expression levels of microRNAs in milk samples were detected by real-time PCR.The relationship between levels of microRNAs and maternal and infant-related factors was analyzed.Results 1.MiR-146b,miR-155 and miR-30b expressions were abundant both in human colostrums (5.950 ± 0.823,3.899 ± 0.920,4.057 ± 0.604) and mature milk (4.840 ± 0.805,2.128 ± 0.969,4.929 ± 0.566).The levels of miR-146b and miR-155 were higher in colostrum than that of mature milk (t =7.716,10.215,all P ＜ 0.01),while the level of miR-30b was higher in mature milk than that of colostrums(t =-8.626,P ＜ 0.0l).2.Additionally,the level of miR-30b was negatively correlated with maternal pre-pregnancy body mass index (r =-0.298,P ＜ 0.01).3.The levels of miR-146b and miR-30b were higher in mothers giving birth by vaginal delivery than those who underwent cesarean section(t =2.356,3.108,all P ＜0.05).4.The levels of miR-146b and miR-155 were higher in colostrum-fed girls than boys (t =-2.204,-2.985,all P ＜ 0.05).5.The level of miR-146b in mature milk was negatively correlated with 3-month-old infant' s Z score of body weight (r =-0.425,P ＜ 0.05) and body length (r =-0.569,P ＜ 0.01).6.During follow-up,the incidence of baby eczema in breast feeding group (8.82％,3/34 cases) was lower than that in formula milk feeding group(29.17％,14/48 cases) (x2 =5.012,P =0.025).Conclusions The levels of immunocompetent microRNAs in human milk are influenced by the lactation period,maternal prepregnancy body mass index,mode of delivery and infant sex.The immune-related microRNAs in human milk could be involved in the regulation of infant's immunity and growth.
