Methods Retrospective analysis 25 cases of complicated placenta increta between January 2013 and December 2015 in the Third Affiliated Hospital Of Guangzhou Medical University. Grouped into preoperative line 9 cases of ureteral catheter group and without catheter group 16 cases; Conventional hysterectomy group of 17 cases and the posterior hysterectomy group of 8 cases , compare the operation time , postpartum hemorrhage , blood transfusion amount , bladder injury or ureteral injury rate , rate of transferred to the ICU and hospital stay. Results 76% appear repeatedly painless vaginal bleeding during pregnancy , 56% appear bleeding before delivery. Prenatal diagnosis of 17 cases (68%). The preoperative line cystoscopy + bilateral retrograde ureteral catheter or after the posterior hysterectomy , shorter operation time , less postpartum hemorrhage , reduce blood transfusion volume , no urinary tract injury rate, transferred to the ICU rate is low, the difference was statistically significant (P < 0.05). Conclusions We should attach importance to repeated painless vaginal bleeding , improve prenatal diagnostic rate of complicated placenta increta. The perioperative managementis more comprehensive , effective and standard participation , preoperative ureteral catheter and the posterior hysterectomy can effectively reduce the maternal adverse perinatal outcomes.

High price and poor stability of both crocin-1 and crocin-2 reference substance have become obstacles to HPLC assay of Croci Stigma. A new method based on reference extract was proposed. In this study, the reference extract was prepared from gardenia yellow which is cheap and easy to get The content of crocin-1 and crocin-2 in reference extract was determined and factors affecting stability of reference extract were investigated. Twelve batches of Croci Stigma were analyzed with reference extract and reference substance respectively. The results showed no difference. The presented method is feasible for quality control of Croci Stigma and reference extract is suitable to replace reference substances in assay.

Objective To determine the random spot albuminuria to creatinine ratio (ACR) of normal pregnant women , to track the pregnancy outcome , and to discuss the predictive value of ACR in women with hy-pertensive disorders complicating pregnancy (HDCP). Methods Except for 87 pregnant women suffering from HDCP, 2 038 pregnant women were enrolled in this study. ACR, routine examinations of blood and urine, blood biochemical, 24-hr urinary protein were determined. Results ACR, but not 24-hr urinary protein level,was sig-nificantly higher in women with HDCP. There was positive correlation between the ACR and 24-hr urinary protein quantitation. Age, gestational weeks, ACR, red blood cells, fasting plasma glucose, serum creatinine, total pro-tein were the independent risk factors for HDCP. The sensitivity , specificity and optimal cut off value of ACR for predicting HDCP were 0.78, 0.63, 1.46 mg/mmol. Conclusions There was positive correlation between ACR and 24-hr urinary protein quantitation , and ACR provided a more sensitive pathway for early predictionof HDCP.

OBJECTIVETo study the roles of stromal interaction molecule 2 (STIM2) and transient receptor potential canonical 3 (TRPC3) in extracellular Ca(2+)-sensing receptor (CaR)-induced extracellular Ca2+ influx and the production of nitric oxide (NO) in human umbilical vein endothelial cells (HUVEC).
METHODS(1) The interaction of STIM2 and TRPC3 was determined using the immunofluorescence technique. (2) The expressions of STIM2 and TRPC3 genes were silenced in HUVEC by transfection constructed STIM2 and TRPC3 RNA interference plasmids. The interference efficiency of STIM2, TRPC3 protein and mRNA levels were determined by Western blot and real time RT-PCR, respectively. (3) The second to fifth passage of HUVEC were divided into: STIM2-002 short hairpin RNA (STIM2-002 shRNA ) + spermine + Ca2+ group and TRPC3-004 short hairpin RNA (TRPC3-004 shRNA ) + spermine + Ca2+ group; control group (spermine + Ca2+ group) and vehicle+ spermine + Ca2+ group. The four groups of cells were incubated with CaR agonist spermine, the intracellular Ca2+ concentration ([Ca2+]i) was detected using the fluorescence Ca2+ indicator Fura-2/AM, and the production of NO was determined by DAF-FM (NO fluorescent probe) of each group in HUVEC.
RESULTS(1) Immunofluorescence technique results showed that STIM2 and TRPC3 proteinswere present in the cytoplasm of HUVEC. (2) The results of transfection constructed STIM2 and TRPC3 RNA interference plasmids demonstrated that shRNA targeted to the STIM2 and TRPC3 genes decreased STIM2 and TRPC3 mRNA levels by 88.2% and 74.0%, respectively (P < 0.05), simultaneously, the STIM2 and TRPC3 protein levels were decreased by 79.9% and 71.8%, respectively (P < 0.05). (3) Compared with spermine + Ca2+ group, the [Ca2+]i and the net NO fluorescence intensity of spermine + Ca(2+) + ShSTIM2-002 group, spermine + Ca(2+) + ShTRPC3-004 group and spermine + Ca2+ Vehicle group were not changed (P > 0.05).
CONCLUSIONSTIM2 and TRPC3 do not participate in CaR-mediated Ca2+ influx and NO production individually.

To study the effect of pulchinenoside (PULC) on the Frizzled (FZD) expression of adjuvant arthritis ( AA) rats. AA rats were prepared through the toe injection with complete Freund's adjuvant to culture fibroblast-like synoviocytes (FLS). The effect of the oral administration with PULC on the FZD8 expression was detected by the real time qPCR. The effect of FZD8 knockout on the expressions of IL-1, IL-6, IL-8 were detected by MTT and ELISA. The role of miR-375 in the abnomal expression of FZD8 was detected by the real time qPCR. The results showed signfiicant decrease in the FZD8 expression among AA rats, FLS proliferation ater FZD8 knockout and IL-1, IL-6, IL-8 expressions and notable increase in miR-375 expression after the oral administration with PULC. The up-regulated miR-375 expression can inhibit the FZD8 expression. PULC may inhibit the FZD8 expression by up-regulating the miR-375 expression.
