Objective:To analyze the infection results of The immunofluorescence detection of respiratory syncytial virus (RSV) in huazhou region from 2009 to 2010.Methods: The N gene sequence of RSV was taken as a reference to design specific primers and TaqMan fluorescent probe and to establish real-time The immunofluorescence method to detect sensitivity and specificity.21548 swab samples of children with acute respiratory infections in huazhou region from 2009 to 2010 were tested with real-time fluorescence. The immunofluorescence method.Results: The specificity and sensitivity of real-time fluorescence. The immunofluorescence method for detection of RSV infection were higher, without cross-reactivity to other respiratory viruses.10,477 cases of clinical specimens in 2009 were detected, with positive RSV infection rate of 9.73%, by real-time The immunofluorescence method detection. Positive detection rate of RSV infection had two peaks, which lied in February and December; the positive rate was 11% and 11% respectively. RSV infection rate was the highest for children under 6 years old.Conclusion: Real-time fluorescence features convenient detection, high specificity, and high sensitivity, which can be used for clinical detection of RSV infection. From 2009 to 2010, RSV infection remains a major pathogen of acute respiratory infections in children in huazhou region.

Offering designing experiment is the developing direction of experiment teaching reforms. But in the practice,there are various of obstacles which prevent the reforming process.

Objective To evaluate the long-term molluscicidal effect of suspension concentrate of niclosamide (SCN) spraying in marshland regions of the Yangtze River. Methods A marshland with Oncomelania snails in Yangzhong City, Jiangsu Province, was selected as the study spot, and a dose of 6-8 g/m2 of SCN was sprayed yearly for four successive years, and the status of snails was investigated. Results From 2004 to 2007, the average densities of living snails were 6.00, 4.25, 2.04, 1.95 snails/0.1 m2, respectively before the use of molluscicide, and 0.86, 0.86, 0.23, 0.16 snails/0.1 m2, respectively after that. The average densities of living snails before and after the use of molluscicide reduced year by year, and the reduction rates of average densities of living snails were 85.67%, 79.76%, 88.49% and 91.78%, respectively from 2004 to 2007. The rate of frames with snails after the use of molluscicide was 73.46% in 2007, with a reduction rate of 86.85% compared with 9.66% of that before the use of molluscicide in 2004, and the average density of living snails reduced from 6.00 snails/0.1 m2 to 0.16 snails/0.1 m2, with a reduction rate of 97.33%. Conclusions After the spraying for four successive years, the density of snails reduces significantly and the molluscicidal effect is stable and reliable. SCN is a formulation of molluscicide for long-term application in marshland regions.

OBJECTIVETo summarize and analyze rules for acupoint selection and prescription composition in clinical literature regarding acupuncture for polycystic ovary syndrome (PCOS).

METHODSCHKD, VIP and Wan-fang databases were retrieved. The clinical literature data included in the study was collected. The descriptive statistical analysis was conducted on the main acupoints, main meridians of main acupoints, distribution of main acupoints, application of special points and rules for acupoint composition.

RESULTSFifty-two articles were included, involving 55 main acupoints with a total frequency of 375. The most frequent acupoints of acupuncture for PCOS were Sanyinjiao (SP 6), Guanyuan (CV 4), Zigong (EX-CA 1), Zhongji (CV 3) and Qihai (CV 6). The meridians of main acupoitns were conception vessel, spleen meridian of foot-taiyin and stomach meridian of foot-yangming. The main acupoints were distributed in the lower abdomen, lower limbs and back. In the special points, the use of front-mu points, five-shu points and back-shu points was more frequent. The prescription was usually consisted of 5 to 7 acupoints, (6. 9 ± 3. 6) acupoints in average.

CONCLUSIONIn the modern treatment of acupuncture for PCOS, Sanyinjiao (SP 6), Guanyuan (CV 4), Zigong (EX-CA 1), Zhongii (CV 3) and Qihai (CV 6) are most used. With the theories of meridian and zang-fu as essential references, the acupoint selection is based on disease differentiation and meridian circulation. Additionally, the methods for selecting the adjacent points and the distant points are adopted.

Objective To investigate the effect of different intestinal cleaning methods on bowel preparation for laparoscopic peritoneal vaginoplasty.Methods One hundred patients undergoing laparoscopic peritoneal vaginoplasty were divided into experiment group and control group with 50 cases in each group .For bowel preparation,the experiment group was managed with oral sodium phosphate salt solution of 45 mL and the control group with oral senna leaf of 30 g in boiled water.The two groups were compared in terms of intestinal cleaning degree,adverse reactions and postoperative exhaust time.Results The incidence of adverse reactions in the former group was significantly lower than the control group.Degree of bowel cleaning satisfaction was significantly better than that of the control group and the postoperative exhaust was significantly earlier than that in the control group(P<0.05).Conclusion The method of oral sodium phosphate salt solution for bowel preparation for laparoscopic peritoneal vaginoplasty can improves the intestinal cleanliness,reduce incidence of intestinal adverse reaction and promote postoperative exhaust so that it can improve postoperative intestinal restoration of kinetic energy.

Objective:To investigate the migration and odontogenesis of rat dental pulp cells transfected with adenovirus vector enco-ding cadherin-11.Methods:The dental pulp cells were cultured and transfected with pDC316-mCMV-EGFP-Cadherin-11.Cad-11 protein expression of the cells was examined by immunohistochemistry staining.The odontogenic differentiation of the cells was studied by alizarin red staining and ALP staining.The adhesion and migration of the cells were tested.Results:Transfection of pDC316-mC-MV-EGFP-Cadherin11 promoted Cad-11 protein expression and ALP activity,increased calcified nodule formation(P <0.05),adhe-sion and migration of rat dental pulp cells(P <0.05).Conclusion:Cadherin-11 may promote the odontoblast differentiation and mi-gration of rat dental pulp cells.

Hyperthermia is a significant and promising technique for tumor treatment. Temperature is the key parameter which influences the treatment effectiveness.

Objective To investigate the effects of siRNAs targeted protein kinase C ?(PKC?) on the proliferation and apoptosis of A549 cell line.Methods Six PKC? siRNAs were designed and chemical synthesized. Candidate PKC? siRNA was transfected into A549 cells,PKC? mRNA level was determined by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). Then,the effects of more effective PKC? siRNAs on A549 were further investigated by using clone formation assay,Hoechst 33258 staining,propidium iodide (PI) staining,Annexin V-FITC and PI dual staining and western blot. Results Six candidate PKC? siRNAs were designed and named as No.1,No.2,No.3,No.4,No.5 and No.6 PKC? siRNA. Compared with controls,PKC? mRNA levels were all significantly downregulated and the cell proliferation was inhibited in A549 cells treated with candidate PKC? siRNAs except No.5 (P
