Objective To explore the clinical value of transvaginal three-dimensional color Doppler ultrasound in assessing effects of Chinese herbal drugs on improving endometrial receptivity in patients with thin endometrium.Methods A total of 76 cases of patients diagnosed with thin endometrium in Jiangbei District Hospital of Traditional Chinese Medicine from June 2015 to October 2016 were selected and treated with Chinese herbal prescription for three months.The endometrial thickness,endometrial volume and blood flow indexes before and after treatment were measured by using transvaginal three-dimensional color Doppler ultrasound.Results After 3 months treatment,the endometrial thickness and endometrial volume were increased,and the pulse index (PI) and resistance index (RI) of endometrial blood flow were decreased,compared with those before treatment,there were statistically significant differences(P＜0.05).The results of three-dimensional color Doppler ultrasound indicates that after 3 months treatment the vascularization index (VI),flow index (FI) and vascularization flow index (VFI) were significantly higher than those before treatment,there were statistically significant differences (P＜0.05).Conclusion The Chinese herbal prescription could increase the thickness and volume of endometrium,augment blood supply,and improve endometrial receptivity significantly.Transvaginal color three-dimensional Doppler ultrasound is a convenient and objective method for evaluating clinical efficacy of Chinese herbal prescription in patients with thin endometrium,which has high practical value.

Objective:To propose a method to evaluate the total body water (TBW) of patients on hemodialysis with urea kinetic model (UKM), and compare it with body surface bio-impedance spectrum (BIS) analysis. Methods:We enrolled 24 adult patients with end stage renal disease (ESRD) without hyper-catabolism in our dialysis center. All of them had been on hemodialysis for more than 3 months. TBW was measured with BIS analysis immediately before and after dialysis session, and one hour after hemodialysis session. Spent dialysate was collected; blood samples were taken before and one hour after hemodialysis session, TBW before hemodialysis session were calculated by UKM. Results:Patients were 6 men and 18 women, the average age was (51.2?13.5) years and the average time on dialysis was (33.2?36.7) months. Causes of ESRD included chronic glomerulonephritis (8 patients), diabetic nephropathy (1 patients), hypertensive renal damage (1 patients), interstitial nephritis(two patients), chronic pyelonephritis (two patients). The average ultrafiltration volume was (2.7?1.0) L (0.5-4.4 L) . Plasma urea concentrations were (23.06?5.76) mmol/L and (8.15?2.06) mmol/L before and one hour after hemodialysis session, respectively. There was no significant difference between TBW measured immediately after and one hour after hemodialysis session with BIS analysis [(29.9?8.8) L and (29.8?8.6) L, respectively; average difference was (0.1?0.9)L, P=0.70]. These two measurements correlated very well (Pearson r=0.99, P

Objective:To investigate the effect of miR-154 on the apoptosis of hepatic stellate cells (HSC-T6). Methods:Hepat-ic stellate cells (HSC-T6) were transfected with miR-154 mimics and miR-154 inhibitor, and the cells were trandfected with mimics NC and inhibitor NC as the negative control. The effects of miR-154 on the proliferation of HSC-T6 were detected at different time points by CCK-8. A flow cytometry with double staining of Annexin and PI was used to detect the cell cycle and apoptosis rate of HSC-T6. Results:The proliferation ability of the cells was increased,the apoptosis rate was decreased significantly, and the proportion of cells in G0/G1 phase were decreased, and those in G2/M phase were increased significantly after transfected with miR-154 mimics. The proliferation ability of the cells was decreased,the apoptosis rate was increased significantly, and the proportion of cells in G0/G1 phase were increased, and those in G2/M phase were decreased significantly after transfected with miR-154 inhibitor. Conclusion:MiR-154 can promote the proliferation of HSC-T6 and inhibit the apoptosis of HSC-T6.

Objective:To summarize the single nucleotide polymorphisms ( SNPs) in ABCC2 and the effect on clinical drug appli-cation. Methods:According to the related articles published in domestic and abroad, the correlation between the single nucleotide pol-ymorphisms in ABCC2 and drug responses was classified and summarized. Results:ABCC2 translocator played an important role in the transmembrane transport of many physiological compounds and exogenous compounds. Numerous studies have demonstrated that the single nucleotide polymorphisms in ABCC2 possibly affected the expression or activity of ABCC2, which leading to the variation in the absorption, distribution and excretion of certain drugs and toxicants. However, the limitation and controversy were still emerged in the results. Conclusion:The influence of ABCC2 single nucleotide polymorphisms on clinical drug application shows significantly referen-tial value for the guidance of medication and the evaluation of efficacy, however, it can not be used as the only indicator yet.

Objective To evaluate the relationship between the clinicopathological factors, prognosis and the expression of p16 and c erbB 2 protein in primary breast cancer. Methods The expression of p16 and c erbB 2 by immunohistochemical method was observed in 50 patients with primary breast cancer and the detection of p16 by polymerase chain reaction(PCR) and the point mutation of p16 by PCR single strand conformational polymorphism(SSCP) were detected in 20 patients with breast cancer. Results Among the cancers, positive expression of p16 protein was found in 17(34.00%) cases, c erbB 2 protein positive expression in 24(48.00%) cases. No homozygous deletion in p16 gene was found. However, exon2 point mutation of p16 gene was found in 1 of 20 breast cancer. The results showed no relationship between p16 expression and clinicopathological factor or prognosis. Positive expressions of c erbB 2 protein were often found in breast cancer with lymph node metastasis(P=0.0237) with a poor 5 year survivalrate(P=0.0169). There was no consistent relationship between the expression of p16 and c erbB 2 protein. Neither p16 nor c erbB 2 protein expression could be as an independent prognostic factor. Conclusions The patients with breast cancer of positive expression of c erbB 2 protein has a high lymph node metastasis rate and a poor survival rate. The point mutation rate of p16 gene is lower in primary breast cancer, and it can be a molecular events in advanced primary breast cancer.

Objective To study the relationship between tyrosine phosphorylation(TP)and protein expression of insulin receptor substrate-1(IRS-1)and insulin resistance in patients with gestational diabetes mellitus(GDM).Methods IRS-1 expression and TP in skeleton muscle tissue were determined by Western blot and immunoprecipitation in women with GDM(GDM group,n=22),normal pregnant women(normal pregnancy group,n=22)and normal nonpregnant women(normal nonpregnant group,n=13).Fasting plasma glucose(FPG)and fasting insulin(FINS)were measured by oxidase assay and immunoradioassay. Results(1)The levels of FPG,FINS,and insulin resistance index were calculated according to homeostasis model assessment [ HOMA-IR;(5.6?0.8)mmol/L,(15.4?5.1)mU/L,and 1.2?0.5 ] in GDM group were significantly higher than those in normal pregnancy group [(4.4+0.5)mmol/L,(10.6 ?3.1)mU/L,and 0.8?0.3;P

Objective To observe the aging,apoptosis,cell cycle arrest and oxidative stress in human skin fibroblast(HSF)induced by UVB,and to detect the expression profiles of p66Shc,a determinant of oxidative stress response and life span,in this process.Methods HSF cells were exposed to UVB at a subcytotoxic dosage twice a day for three days.The cells without exposure served as control.After another 24-hour culture,SA-β-Gal staining was performed to evaluate the senescence state of the cells,flow cytometry to observe cell apoptosis;cell cycle arrest was detected by serum starvation and flow cytometry:ELISA was applied to detect intracellular levels of superoxide dismutase(SOD)and malondialdehvde(MDA),and Western blotting to analyze the expression of p66Shc protein.Results The percentage of cells positive for SA-β-Gal staining increased from 0 to 98.3% after UVB radiation,which strongly suggested an aging state of HSF cells.The percentage of apoptotic cells increased from 0.96% to 37%.and 80.07% of the HSF cells were arrested in G0/G1 phase following the irradiation.Intracellular SOD activity decreased from(52.35±4.97)ng/g to(7.81±0.68)ng/g(P＜0.01).while intracellular MDA was found to increase from(3.52±0.34)ng/g to(33.91±3.20)ng/g(P＜0.05).The p66Shc protein was found to be weakly expressed in HSF in 24 hours following the exposure to UVB,and a stronger expression was noted 48 hours later.Conclusions HSF cells are induced into a state of senescence associated with oxidative stress after UVB irradiation,which may be applied as an in vitro model in aging research.The expression of p66Shc is increased in HSF during this process,and further studies are needed to explore the relation between p66Shc and oxidative stress as well as cellular aging.
