Objective To evaluate the control effect of comprehensive measures of schistosomiasis after its transmission in?terruption in Kaihua County,Zhejiang Province,so as to provide the references for further consolidation of schistosomiasis con?trol. Methods The data of Oncomelania hupensis snail survey and control,as well as environmental reform in Kaihua County were collected and analyzed from 1996 to 2015. Results From 1996 to 2015,totally 2 635 snail habitats and 102.75 hm2 area with snails were found,and 125.4 thousand snails were dissected and no one was schistosome infected. The accumulated snail control area was 4 932.98 hm2,and the area with snails was effectively reduced by the comprehensive control measures. Conclu?sion The schistosomiasis control effect could be consolidated by the comprehensive control measures emphasizing environmen?tal reconstruction,and the snail surveillance work still should be strengthened.

The present paper intends to discuss the antioxidant and tyrosinase inhibition effect of solanesol from three aspects of ultraviolet radiation and free radical scavenging. The paper makes a survey on diurnal variation rule of the minimum ultraviolet transmittance and ultraviolet transmittance of solanesol, hydroxyl (OH) free radical scavenging method of Smirnoff reaction system model, superoxide anion O2- free radical scavenging method of pyrogallol autoxidation, and the inhibitory effect of solanesol on tyrosinase activity by enzyme kinetic method. The experiment results showed that solanesol could effectively scavenge lipid radicals to block lipid peroxidation, and inhibit effects on tyrosinase. Solanesol is a natural extract which could be used to prevent senile atrophy of human skin and senile plaque.

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.

AIM: To study the chemical components from the bioactive extract of Chuanminshen violaceum Sheh et Shan in Sichuan province. METHODS: The isolation and purification of this extract were conducted by means of silica gels column chromatography.The structures of the compounds were elucidated based on their physical,chemical features and spectrum data. RESULTS: 8 compounds were isolated from the extract.They were elucidated as hexadecanoic Acid(A),2,6-dimethoxybenzoic acid(B),succinic acid (C),combination of sigmasterol and sitosterol(1(∶)1)(D),chrysophanol(E),8-hydroxy-5-methoxypsoralen(F),4-hydroxy-3-methoxybenzoic acid(G) and stigmasteryl 3-O-?-D-glucopyranoside(H). CONCLUSION: Compounds B,C,E,G were isolated from Chuanminshen violaceum for the first time.

Objective To analyse incidence of the severe complications of hypertensive disorder complicating pregnancy and the influence on the outcome of pregnancy.Methods A retrospective study of 4107 cases among 71 020 cases who delivered in hospitals from 1995 to 2004 in Guangzhou was conducted. Results The morbidity of hypertensive disorder complicating pregnancy was 5.78%,in which the morbidity of severe pre-eclampsia was 27.78% (1141/4107),of mitis pre-eclampsia was 72.22% (2966/4107). Maternal mortality rate was 0.19% (8/4107),and the specific mortality rate was 11.26/100 000.The proportion of severe complications of hypertensive disorder complicating pregnancy from high to low was as follows:placental abruption 1.68% (69/4107),DIC 1.36% (56/4107),hypertensive disorder complicating pregnancy induced cardiopathy(induced cardiopathy) 1.05% (43/4107),renal failure 0.97% (40/4107),cerebrovascular accident 0.58% (24/4107),and hemolysis,elevated liver enzymes and low platelet (HELLP) syndrome 0.51% (21/4107).Mortality caused by severe complications of hypertensive disorder complicating pregnancy were as follows:cerebrovascular accident 17% (4/24),HELLP syndrome 10% (2/21),DIC 5% (3/56) and induced cardiopathy 2% (1/43).The proportion of perinatal mortality from severe complications were as follows:placental abruption 43% (33/77),HELLP syndrome 42% (10/ 24),DIC 34% (22/64),renal failure 25% (11/44),cerebro vascular accident 24% (6/25)and induced cardiopathy 16% (8/49).Conclusions (1) The morbidity of severe complications from high to low are: placental abruption,DIC,induced eardiopathy,renal failure,eerebro vascular accident and HELLP syndrome.(2) The main causes of mortality for gravida and puerperant are:cerebro vascular accident, HELLP syndrome,DIC and induced cardiopathy.(3) The major complications harmful to perinatal newborns are in the order of:placental abruption,HELLP syndrome,DIC,renal failure,eerebro vascular accident and induced cardiopathy.

Pseudorabies virus (PRV) is a swine herpesvirus of the Alphaherpesvirinae subfamily and a pathogen of swine resulting in devastating disease and economic losses worldwide. Cre/loxP site-specific system has the character of site specific, time specific, tissue specific and high efficiency in recombination, which makes this system universal in vivo and in vitro recombination of bacteria, fungus, plants, insects and mammals. A recombinant PRV which contain a loxP site in TK locus by using Cre/LoxP recombinant system was construsted. A pair of primers were synthesized according to the pEGFP-C1 sequence published on GenBank, and were used to amplify the EGFP gene expression cassette with two loxP sites flanking each side. This target gene was cloned into pSKLR, the resulting transfer vector pSKLR-GFP-loxP was then cotransfected into 293T cells with PRV SH strain genomic DNA. The recombinant virus rPRV1 was selected and purified in TK-143 cells by choosing fluorescent expressing plaques. Cre expression vector pOG231 was cotransfected into 293T cells with rPRV1 genomic DNA. The second recombinant virus rPRV2 was obtained, which contains only one loxP site in TK locus. Sequencing results of rPRV2 TK gene indicated that 34bp loxP site was inserted into rPRV2 genome and there were 270bp deletion in TK gene. PCR amplifying different generations of rPRV2 TK gene showed that the mutant was stable when passages in RK-13 cells. TCID_ 50 assay indicated that rPRV2 grows well on RK-13 cells. The LD_ 50 test results on BALB/C mice suggested that the virulence of rPRV2 was reduced. As a conclusion, the report gene GFP expression cassette was removed successfully from rPRV1 genome and only one LoxP site was leaved in rPRV2 genome by using Cre/LoxP recombinant system.

Objective To observe the effects of asthmatic children treated by inhaled salmeterol xinafoate and fluticasone propi-onate powder. Methods One hundred and fourty cases of moderate and severe asthmatic children were treated in non- acute period aged from 4 to 14 years by inhaling salmeterol xinafoate and fluticasone propionate powder, compared with control group treated by flu-ticasone propionate in 106 cases, and the pulmonary function was monitored simultaneously. Results The total effective rate of the treatment group and control group were 99. 3 % , 99. 1 % , respectively.The pulmonary function indexes such as the first one second expiration volume(FEV1), flow velocity of 50 % expiration vital capacity(FEF50%), peak expiration velocity(PEF1) after being treated 4 months was improved significantly compared with those before treatment.The difference between them was statistically significant (P
