Objective To study the self-identity and security of patients with obsessive-compulsive disorder (OCD) Methods According to the Chinese Classification of Mental Disorder,Third Edition,63 inpatients and outpatients with OCD and 61 healthy controls were recruited to investigate with self-identity scale(SIS),security questionnaire (SQ),Yale-brown obsessive compulsive scale (Y-BOCS),and self-made questionnaire.Results Compared with controls,patients had lower self-identity (50.81 ± 7.52 vs 55.10 ± 6.86,P ＜ 0.01)and security(50.09 ± 11.65 vs 58.87 ± 10.22,P ＜ 0.01)than healthy controls.Female patients had lower self-identity (48.31 ±7.68 vs 52.57 ±6.98,P＜0.05) than male patients.There were correlation between self-identity and Y-BOCS (r =-0.404,P ＜ 0.01),security and Y-BOCS (r =-0.314,P ＜ 0.05),self-identity and course of disease (r =-0.284,P ＜ 0.05),security and course of disease (r =-0.259,P ＜ 0.05) self-identity and security (r =0.698,P＜ 0.01) Conclusion OCD patients have lower self-identity and security.The self-identity and security reduce with the symptoms getting worse.Low self-identity and security maybe characteristic of OCD patients.

Objective To explore the characteristic and pattern of children injury of Zhejiang Province,and provides scientific evidence for the prevention and control strategy of children injury. MethodChildren diagnosed as injury at emergency department in sentry hospitals (Tnere are 5 monitoring sites for injury surveillance in Zhejiang in 2005: Jinhua, Shengsi, Tongxiang, Yinzhou dislrict of Ningbo, Hailing; each monitoring site has 3 sentry hospitals: one county level hospital, one town center hospital and one town level hospital) from January to December,2005 were investigated by trained doctors or nurses in emerncy department. The investigation included basic information, when injury happened, where injury happened and type of injury. Children were investigated when they were conscious, and their parents or accompanies could answer if they were not able to. The contents of investigation were kept private. The distribution of variables which included sex, age, when injury happened, where injury happened, why injury happened and severity level were described mainly with proportion and means, and chisquare test was used to analyze the proportion difference. RemitsA total of 1 794 injury cases were recorded in 2005 among which 67.56% were male and 32.44% were female. The majority were native people and the average age was 7.33±3.84 years old. The injury occurred mostly at home and was of high frequent occurrence from April to November. The most common causes of injury were tumble (47.94%).traffic accident (17.17%) and blunt injury(10.26%). The injury happened mostly during spare time(67.66%), and then school aetivities(11.25%)ant]sports activities(9.96%). Totally 90.33% of the injured children went home after been treated, 1.40% stayed for obsrvafion, 7.04% were in hospital, 0.56% were transferred to other hospitals, 0.22% died and 0.45% unknown. The slight superficial injury and moderate injury were the most common injuries. The most common three types of injury were haemaloma and stasis injury(31.29%), superficial abrased wound(23.69%) and bone fracture(8.67%). Among the injury, 39.47% were head injury, 25.80% were upper limb, 28.55% were lower limb, 4.81% were trunkand 1.38% wereothers. Conclusions The most common three types of injury in Zhejiang province were haemawma and stasis injury, superficial abrased wound and bone fracture. The main reasons of injury were falling injury,traffic accident injury and blunt injury. The injury happened mostly during spare time, and scbool activities and sports activities. Thus, safety education and safety protection should be strengthened to reduce children injuries.

Objective: To investigate the stress and coping strategy of rescue surgical staff early after earth-quake. Methods: The self reporting questionnaire (SRQ-20) and coping styles questionnaire (CSQ) were distribu-ted to 37 surgical staff and 44 psychiatric staff (the control group) in Chengdu City 2 weeks after Wenchuan earth-quake. The results were analyzed by t test, correlation analysis and logistic regression analysis. Results: The grades of rescue surgical staff in SRQ-20 and negative coping styles factor was higher than that of the psychiatric staff [(9.3±4.7)vs.(3.2±3.9), (29.8±6.2) vs.(26.1±7.1); Ps<0.05] . The SRQ-20 score in rescue surgical staffs was positively correlated with negative coping styles factor (r=0.50, P=0.002) and age (R~2=0.168, P=0.012) . Conclusion: Surgical staff, especially the elder, have more intensive acute stress reaction. It is essential to publicize psychologic knowledge and improve mental health of surgical staff.

[Objective] This study compared outcomes of in vitro maturation (IVM) and in vitro fertilization (IVF) intracytoplasmic sperm injection (ICSI) cycles after IVM of immature germinal vesicle (GV) oocytes.[Methods] ICSI was performed on metaphase II (MII) oocytes retrieved in 163 IVF-ICSI cycles (group I;n ＝ 987) or matured from GV stage oocytes in IVF-ICSI ( group II;n ＝ 132) and 37 IVM cycles ( group III;n ＝ 235).Fertilization and cleavage rates and embryo quality were compared among the three groups.[Results] The fertilization rate,cleavage rate and top quality embryos rate were higher in group I than group II and group III (84.9%,98.1%,and 61.6%;72.0%,90.5% and 22.1%l;75.3%,94.4%,and 25.1%,respectively).Blastomere numbers and morphology scores were highest in group I (P ＜ 0.05),but no significant differences existed between group II and group III.[Conclusion] The morphology of embryos developed from in vivo MII oocytes was superior to those from in vitro matured MII oocytes.No significant difference was observed in embryo morphology from immature GV oocytes in IVF and IVM cycles.

Objective: To investigate the pharmacokinetics of rhein (RH) in rat plasma and kidney simultaneously. Methods: An HPLC method was developed to determine the concentration of RH in rat plasma, which was corrected with protein binding. Renal microdialysis (MD) technique was employed to collect dialysate sample continuously. Then the MD samples were detected by HPLC-MS/MS method. Results: RH was distributed into kidney of rats rapidly after administration. The maximum concentration of RH in rat kidney was reached at 1 h followed by continuously decreased. During the whole process, the concentration of RH in rat kidney was significantly lower than that in plasma after administration. The MRT of RH in plasma and kidney was (87.217 ± 29.889) and (122.387 ± 12.521) min, respectively. The areas under the curve (AUC) of RH in plasma and kidney were (114.236 ± 45.585) and (16.596 ± 1.732) μg·min/mL, respectively. The kidney penetration was 0.161 ± 0.056. Conclusion: Simultaneous pharmacokinetic study in rat plasma and kidney is an effective method to investigate drug kidney penetration. RH can penetrate rat's kidney after administration to exert its effect.

OBJECTIVE: To establish the high performance liquid chromatography (HPLC) fingerprint of the caulis of Chimonanthus nitens and evaluate the product quality by chemometrics analysis method. METHODS: The method was developed on an Amethyst C18-H column(4.6 mm×250 mm, 5 μm)by gradient elution with acetonitrile-water (containing 0.1% formic acid) as mobile phase at a flow rate of 0.8 mLmin-1. The column temperature was maintained at 28℃, and the detection wavelength was set at 254 nm. The main characteristic peaks was identified by comparing the retention time and UV absorption characteristics. Then 10 batches of the caulis of Chimonanthus nitens were evaluated by similarity assay, HCA, and PCA. RESULTS: The HPLC fingerprint of the caulis of Chimonanthus nitens was established and three main peaks were identified. The similarity of 10 batches of the caulis of Chimonanthus nitens was about 0.978 0 to 0.991 9. CONCLUSION: The established method can be used for the quality control of the caulis of Chimonanthus nitens.
