Objective To study the clinical characteristicsand perioperative managementof complicated placenta increta, effectively reduce the maternal adverse perinatal outcomes. 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.

Objective To explore the effects of application of the new model of evidence-based land humanized nursing in patients with universal pustular psoriasis.Methods Divided 84 patients with universal pustular psoriasis into the experimental group (42 cases) and the control group (42 cases) randomly.Evidence-based questions were raised according to the requests about humanized nursing of patients in the experimental group,and then retrieved and screened literature,sought high-level evidence,combined with previous nursing experience,developed new evidence-based and humanized nursing programs and implemented in the experimental group.The control group used conventional care program.Two weeks after admission,pain,anxiety,depression degree and the complications of two groups were compared.Results Two weeks after admission,the patients with 0 to 5 levels of pain in the experimental group was 0,5,26,7,4 and 0 cases respectively,which in the control group was0,0,0,12,20 and 10 cases respectively,the difference was significant between the two groups (U=6.957,P＜0.01).Anxiety and depression scores in the experimental group was (41.35±4.30) and (42.55±7.71) respectively,which in the control group was (51.31±4.56) and(50.36±6.89) respectively,the difference were significant between the two groups (t=10.540 and 4.893,P＜0.01).Conclusions The new model of evidence-based and humanized nursing can effectively improve the effects of humanized nursing in patients with universal pustular psoriasis.

Objective To understand the screening results and positive lesion situation of colonoscopy screening among high risk urban population of colon cancer in Chongqing Nan'an District to provide a basis for the community heath guidance.Methods The high risk subjects of colon cancer screened according to the item of the Early Diagnosis and Early Treatment of China Urban Cancer and in our center for completing colonoscopy screening during 2013-2016 were collected and analyzed on the positive rates of various lesions.Results A total of 435 subjects were included,141 positive cases were found with the total positive rate of 32.41％ (141/435),in which 75 cases were male positive with the positive rate of 47.47％ (75/158),and 66 cases were female positive with the positive rate of 23.83 ％ (66/277),the polyps detective rate was 28.27 ％ (123/435),tumor-like lesion detective rate was 7.59％(33/435),the adenocarcinoma detection rate was 0.46％ (2/435);the total positive rate of male was higher than that of female(x2 =25.669,P＜0.01).Conclusion The sequential screening mode in which the high risk population preliminarily screened out by community then performs colonoscopy examination has an important significance for discovering the intestinal tract lesion.

By means of comparing biomasses of biodegradation fungi,Fusarium sp.HG-P-01 for ?-cypermethrin,a synthetic pyrethroid insecticide used widely in China,in five different media,the Czapek-Dox medium was selected as the best medium for mycelia growth.Furthermore,an experiment of central composite rotatable design(CCRD) was used to optimize the content of nutrient components.The optimal composition of C,N and P in media for HG-P-01 were 20.94 g/L,1.82 g/L and 1.66 g/L,respec-tively,in which an expectant or real rate of ?-cypermethrin-degradation got to 96.34% or 93.78% by HPLC for a concentration of 50 mg/L after 24 h treatment.The predicted value in degradation rate model was con-sistent with that from HPLC method.

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.
