Objective To analyze the results of health examination of soldiers stationed on an island,and to explore the health condition of the soldiers and main influencing factors,so as to provide scientific basis for further prevention and intervention.Methods The health examination reports of 507 soldiers stationed on an island were collected and analyzed.These soldiers were stratified according to age and body mass index.Priority diseases and abnormal results were analyzed.Results More than 40 kinds of abnormal results were detected,and the top 5 were sinus bradycardia,fatty liver,high uric acid,high blood pressure,and ametropia.There were significant differences in the detection rates of fatty liver,high cholesterol and kidney stone among all age groups(P<0.05).There were significant differences in the detection rates of fatty liver,high uric acid,high blood pressure and gallbladder polyps among soldiers with different BMI(P<0.05).Conclusion Metabolic diseases have become the main health problems in soldiers stationed on islands.Health care should be intensified,and health management targeting risk factors should be implemented to effectively reduce the prevalence rate and enhance combat capabilities.

Objective:To explore the possible of clinical application value after transferred with day 3 extremely low-grade cleavage-stage embryos during in vitro fertilization and embryo transfer. Methods:The clinical outcomes of four cases with extremely low-grade cleavage-stage embryos on day 3 undergoing IVF-ET were retrospectively analyzed and the related literatures were reviewed.Results:Four cases successfully got pregnant after 12 days of transplantation of extremely low-grade embryos detected by human chorionic gonadotropin testing, and all of them were intrauterine singleton pregnancies. Finally these four patients had successful live births, and three of them were full-term delivery, one of them was delivery prematurely. All the babies were in the good health.Conclusion:There is still a degree of successful pregnancy and live birth rate after transferred with day 3 extremely low-grade cleavage-stage embryos. If the quality of all the embryos was extremely low-grade on day 3, we can provide new attempts and choices for the patients who were often giving up embryos transfer.

To improve the blast resistance of elite rice restorer line Fuhui 673, 3 blast resistance genes Pi-1, Pi-9 and Pi-kh were introduced into Fuhui 673 from a good-quality restorer line Jinhui 1059 through 3 successive backcrosses followed by one selfing using the technique of marker-assisted selection. Ten near-isogenic lines (NILs) of Fuhui 673 carrying the 3 introduced resistance genes were created. Genotype analysis using 68 SSR markers evenly distributed in the genome indicated that 92.96%-98.59% of the NILs' genetic background had been recovered to Fuhui 673. Both indoor and field resistance tests indicated that the NILs and their hybrids with sterile line Yixiang A were all resistant to rice blast, with resistance levels significantly higher than those of controls Fuhui 673 and hybrid Yiyou 673 (Yixiang A  Fuhui 673). In addition, among the 10 hybrids between the NILs and Yixiang A, 2 showed significantly higher yield than and 4 displayed similar yield to that of control Yiyou 673, suggesting that most of the NILs retained the elite characteristics of Fuhui 673. Two new hybrid rice cultivars Liangyou 7283 and Jintaiyou 683 from NIL Line 9 showed high yield, good resistance to blast and moderate growth period in regional trial, suggesting that the NIL Line 9 has a good prospect for application.

Objective To evaluate the role of interleukin-12 (IL-12) in the spinal cord in the maintenance of arthritic pain (AP) in rats.Methods Adult male Sprague-Dawley rats, aged 6-8 weeks,weighing 200-300 g, were randomly divided into 4 groups using a random number table: control group (group C, n=6);AP group (n=9);phosphate buffer solution (PBS) group (n=6);IL-12 antibody group (n =6).AP was induced by injecting 50 μl of complete Freund' s adjuvant into the ankle joint cavity of the left hindpaw of rats anesthetized with isoflurane.Goat anti-rat IL-12 antibody 1.50 μg (20 μl) was intrathecally injected on 9 days after establishment of the model in group IL-12 antibody, while 0.01 mol/L PBS (20 μl) was administered in group PBS.The mechanical paw withdrawal threshold to yon Frey filament stimulation (MWT) was measured before establishment of the model (baseline) and on 9 and 10 days after establishment of the model.The rats were sacrificed after the last measurement of pain threshold, and the L4 6 segments of the spinal cord were obtained for detection of IL-12 expression in the spinal dorsal horn (by immunofluorescence) , and the co-expression of IL-12 and glial fibrillary acidic protein (an astrocyte marker) was examined simultaneously in group AP.Results Compared with group C, the MWT was significantly decreased, and the expression of IL-12 was up-regulated on 9 and 10 days after establishment of the model in AP, PBS and IL-12 antibody groups.Compared with group AP, the MWT was significantly increased at 10 days after establishment of the model, and the expression of IL-12 was down-regulated in group IL-12 antibody, and no significant change was found in the MWT at 10 days after establishment of the model and expression of IL-12 in group PBS.IL-12 was co-expressed with glial fibrillary acidic protein in group AP.Conclusion IL-12 in the spinal cord is involved in the maintenance of AP in rats.

Objective To evaluate the efficacy and safety of domestic palonosetron hydrochlo-ride injection on its prevention of postoperative nausea and vomiting.Methods A multi-centered,ran-domized,double-blinded and placebo-controlled clinical trial was carried out.A total of 281 patients were enrolled,with 141 of patients in study group and 140 of patients in control group respectively. 0.075 mg of intravenous palonosetron hydrochloride injection was delivered in the study group before anesthesia induction.The drug was substituted by 1.5 ml of NS in the control group.All anesthesia inductions were conducted by the intravenous injection of propofol,fentanyl and rocuronium,and were maintained with sevoflurane and fentanyl.Complete remission rate and treatment failure cut-off time of vomiting were evaluated at 0-6 h,6-72 h,0-72 h postoperatively.Results In the study group CR% 0-6 h,6-72 h and 0-72 h were 107 (75.89%),104 (73.76%)and 92 (65.25%),the control group was 81 (57.86%),70 (50%)and 62 (42.86%),CR% of the study group was significantly higher than that of the control group (P <0.01).Insignificant statistical difference but significant clin-ical difference exists in their treatment failure cut-off time,386.5 min and 300.0 min,respectively be-tween the groups.Conclusion Domestic palonosetron hydrochloride injection is safe and effective in the prevention of postoperative nausea and vomiting.

AIM: The goal of the present study was to evaluate the possibility about enterogenous endotoxemia in pathogenesis of hepatopulmonary syndrome. METHODS: The rat model of cirrhosis was prepared with compound factors. A small dose of lipopolysaccharide (LPS) was administered intraperitoneally once to aggravate endotoxemia of animal with cirrhosis. The normal rats injected with LPS or injected with LPS combined with glycine (LPS antagonist) were designed as controls. RESULTS: Hepatopulmonary syndrome of rats with cirrhosis had occurred in the end of eighth weeks. Pulmonary pathological changes of cirrhosis rats were exacerbated after administration of a given dose of LPS. Glycine sharply antagonized the biological effect of LPS in vivo and in vitro, inhibited the production of TNF-? by LPS and alleviated various pathological changes of hepatopulmonary syndrome. CONCLUSIONS: Enterogenous endotoxemia in cirrhosis rats might be an important mechanism in the development of hepatopulmonary syndrome. Endotoxin and its mediating effect by way of cytokines (TNF-?) may play a role in the pathogenesis of hepatopulmonary syndrome.

The effects of GPA, anti-GPA IgG, ?1acid glycoprotcin (?1-AGP), ovomucoid (OM) and wheat germ agglutinin (WGA) on the invasion of erythrocytes by P. falciparum were obseryed in vitro. GPA, anti-GPA IgG and WGA at low concentrations had obviously inhibitory effects on thc invasion. There were hyperbolic relationships between the concentrations of these inhibitors and their inhibition rates. OM, ?1-AGP and non-spccific anti-serum had no obvious effect on the invasion. It is confirmed for the first time from the biological characteristics of receptor-ligand interaction that thc combination of GPA with P. falciparum merozoites has high spccificity, high affinity with a tendency to sa-turation and can produce specific biological effects.
