Objective To express the recombinant protein VP1-Z, and investigate whether VLP-Z has the physiological functions like as wild-type VLP. Methods The expression plasmid pET15b-VP1-Z was introduced into competent E. coil BL21 (DF3)/pLys cells by transformation, and the expression of re-combinant protein VP1-Z was induced by incubation of the cells with IPTG. The protein was prepared as pre-viously described for wild-type VLP. The morphous of VLP-Z were observed by electron microscopy, and the physiological functions of VLP-Z were investigated by hemagglutination test and by immunofluorescence. Re-sults The purified VLP-Z composed of VP1-Z possessed hemagglutination activity and yielded a prominent band of 50×10~3 on SDS-PAGE and staining with Coomassie Brilliant Blue. The VLP-Z exhibited virus-like particles structure like as wild-type VLP with a diameter of 45-50 nm, which was slightly bigger than that of wild-type VLP(42-45 nm). In immunofluorescence test, VP1-Z was detected within the cytoplasm and nu-cleus after HeLa cells were inoculated with VLP-Z. Conclusion The physiological functions of recombinat-ed protein VLP-Z were comparable with wild-type VLP.

Objective To explore the relative factors of polycystic ovarian syndrome (PCOS) in infertile women.Methods Ninety-eight infertile women diagnosed PCOS at affiliated hospital of the Chinese People's Armed Force Logistic college from Jan.2008 to Dec.2012 were served as PCOS group.Two hundred and eighty infertile women with normal ovarian structure according to laparoscopic examination result were selected as control group.The general information,factors related infertile and laparoscopic examination of the two groups were recorded.Results Fifty-one cases (52.0％) in PCOS group were with menarche age earlier than 13 years old,higher than that of control group (113 (40.4％),x2 =4.03,P ＜ 0.05).Eleven cases (11.2％) in PCOS group were with abnormal menstruation cycle,higher than that of control group (12 (4.3％),x2 =6.12,P ＜ 0.05).The incidence of pelvic adhesions in PCOS group was lower than the control group(60(21.1％) vs.224(40.4％),x2 =13.70,P ＜0.05).Irregular menstruation cycle was risk factor of PCOS (OR=1.770,95％ CI:1.09-2.88,P =0.002).Conclusion Women with earlier menarche and irregular menstruation cycle should be paid more attention in terms of PCOS,early screening,discovery,prevention and treatment,so as to reduce the incidence of PCOS induced infertility and the long-term complications.

Smoking and exposure to second hand smoke are the deadly killer of human health. Tobacco kills more than one million people each year in China. According to 2015 Chinese adult tobacco survey, the number of smokers in China increased by 15 million during five years, from 301 million in 2010 to 316 million in 2015. Smoking addiction is a chronic recurrent disease, and its pathogenesis is associated with the mesolimbic dopamine system. In recent years, domestic and overseas scholars studied the brain function of smoking addicts through resting state functional magnetic resonance imaging (fMRI), and found that the brain functional activity of smoking addicts has changed. fMRI can help us understand the mechanism of tobacco dependence, and provide the evidence of diagnosis, treatment and health management of tobacco dependence. In this paper, the present study situation and the application in the field of the treatment and management of smoking cessation of fMRI in smoking addicts are reviewed.

Objective To explore the knowledge, attitude and practice (KAP) about physical restraints among critical nurses in Urumqi, so as to provide basis for further intervention. Methods Totally 660 critical nurses in 21 ICUs from four integrated third-grade class-A hospitals and two third-grade class-A specialized subject hospitals of Urumqi were selected using cluster random sampling and investigated on KAP about physical restraints. Results The average score of physical restraints knowledge was 3.53 ± 1.77. The total awareness rate was 50.43％. The average score of physical restraints attitude was 78.43±11.05. The practice of physical restraints turned out to be at middle level. The average score of physical restraints practice was 128.11 ± 9.60. Conclusions ICU nurses in Urumqi third-grade class-A hospitals generally lack of physical restraints knowledge, however, they were active in physical restraints attitude and practice, there is still some shortcomings, so it is advisable for relevant departments taking targeted intervention measures to improve ICU nurses cognition of physical restraints, then meliorate their physical restraints practice.

This study is to investigate the effect of ZL-004 on normal mouse and mice with leukopenia induced by chemotherapeutic agents. 5-Fluorouracil were administered intraperitoneally to mice to develop leucopenia, and the mice were treated with ZL-004. The number of peripheral leukocytes and the percentage of granulocyte in total WBC were examined. The results are that ZL-004 markedly raise peripheral blood leukocytes in the normal mice and the mice model of leukopenia. So, ZL-004 could protect mice against 5-fluorouracil damage and raise peripheral blood leukocyte. Features of bone marrow smears is myeloproliferative hyperactivity in the mice, particularly the matured granulocytic series were observed. The mechanism of ZL-004 is to act on the mouse bone marrow causing proliferation and differentiation.

Objective To highlight the characteristics of pulmonary sequestration (PS) with combination of practical experience and review of literature. Methods One patient with PS confirmed by biopsy was described and the relevant literatures of 279 cases were reviewed. Results PS can be divided into two types: intralobar type and extralobar type. The percentage of intralobar type is about 78.5%, intralobar type is 13.3%, other unreported is 8.2%. Clinically, PS was often combined by repeated pulmonary infection. The mis-diagnose rate is 72.8%. Etrograde arteriography or enhanced CT scan could find the abnormal artery, from which we can make correct diagnosis. The diagnose rate is 100%. Conclusion For patients with above clinical and X-ray symptoms, PS should be considered. Enhanced CT or retropgrade arteriography examination should be done as soon as possible. Timely diagnosis and surgery treatment are important for curing this kind of disease.

Objective To investigate the pharmacokinetics of propofol when combined with remifentanil in patients with liver cirrhosis.Methods Ten patients (5 males, 5 females) with liver cirrhosis scheduled for endoscopic esophageal varix ligation (test group) and 10 cases (5 males, 5 females) with normal liver function scheduled for gastroscopy (control group), aged 18-55 yr, weighing 40-75 kg, were studied. The patients were unpremedicated. All the patients received iv injection of propofol 1.5 mg/kg and remifentanil 0.5 μg/kg, and 5 min later propofol 0.5 mg/kg and remifentanil 0.2 μg/kg was given again. Blood samples were taken from radial artery before administration and at 2, 5, 10, 15, 20, 30, 45, 60, 80 and 120 min after administration for determination of the plasma propofol concentration using gas chromatography-mass spectrography. The pharmacokinetic parameters were calculated using DAS 2.0 software.Results The pharmacokinetics of propofol was best described by a three-compartment open model. There was no significant difference in the distribution half-life, elimination halflife , terminal half-life, area under the curve and transfer rate constant between the two groups ( P ＞ 0.05) . The apparent volume of distribution of propofol and clearance were significantly increased in test group compared with control group (P ＜0.01) .Conclusion When propofol combined with remifentanil is used in patients with liver cirrhosis, the apparent volume of distribution of propofol and clearance are significantly increased, while no changes in the other pharmacokinetic parameters are found.
