Objective To form a concise and useful warning scale of suicide ideation of inpatients with somatic disease.Methods 2 677 inpatients who were more than 15 years old were randomly selected in a comprehensive hospital during the period of 2010.11-2013.02.Self-rating Depression Scale (SDS),Self-rating Anxiety Scale(SAS) and self-designed questionnaires which included general information,suicide risk factors and somatic disease were applied.Chi square test,partial correlation analysis,t test,correlation analysis and ROC curve analysis were used for statistical analysis.Results 1.The warning scale of suicide ideation which contained 18 items was formed.2.The Cronbach's Alpha reliability of the warning scale was 0.84 and its split-half reliability was 0.60.Criterion-related validity studies showed that the scores of the 18 items were positive correlated with SDS and SAS(r SDS =0.50,r SAS =0.54,P＜0.01).This scale also had good structure validity.3.The ROC curve concluded that the area under curve was 0.83,the sensitivity was 68.40％ and the specificity was 79.20％.Positive and negative predictive values were 21.22％ and 96.83％ respectively.Conclusion The reliability and validity of the warning scale entirely accorded with psychometric demands.It also has good specificity and negative predictive value,so it is suitable for clinical promotion.

To study the relationship between asthma and bronchial hyper responsiveness(BHR).The reactivity of bronchi to inhalation of methacholine, the plasma levels of substance P(SP),soluble P selection (sP selectin),vasoactive intestinal peptide(VIP), and fibronectin(Fn) were assessed in 68 cases of asthma, 62 patients with cough variant asthma(CAV), and 43 healthy subjects.It was showed that the tests of airway reactivity were all positive in 68 cases of asthma and 62 cases of CVA.Dmin in asthma and CVA was(8 81?9 67)u and(5 97?4 37)u,respectively,in these two groups of patients. Dmin in asthma patients was higher than in CAV patients ( P

BACKGROUND: Nerve growth factor (NGF) and myelin-associated glycoprotein (MAG) can promote the repair of peripheral nerve. However, increasing the expression of NGF and MAG in the injured peripheral nerve by transgene technology has not been reported.OBJECTIVE: To investigate the expression of NGF and MAG after adenovirus (Ad) mediated transfection in the injured sciatic nerve in rats.METHODS: Forty Sprague-Dawley rats were randomly divided into normal, model, Ad, NGF and NGF-MAG groups. Sciatic nerve injury models were established in the latter four groups by cutting and suturing the right sciatic nerve. Afterwards, the rats in each group were subject to the intramuscular injection of normal saline, normal saline, Ad (1×108 PFU), Ad-NGF (1×108 PFU), and Ad-NGF-MAG (1×108 PFU), respectively, once every 2 days, for consecutive three times.RESULTS AND CONCLUSION: The expression level of NGF in the rat sciatic nerve in the Ad and normal groups was significantly higher than that in the NGF and NGF-MAG groups (P < 0.05). Compared with the Ad, NGF and normal groups, the expression level of MAG in the NGF-MAG group was significantly increased (P < 0.05). To conclude, the Ad-mediated NGF and MAG after double gene transfection were expressed effectively in the injured sciatic nerve in rats.

Objective To investigates factors affecting the positive rate of blocking antibody treated by paternal lymphocyte immunotherapy in patients with recurrent spontaneous abortion (RSA).Methods From January 2008 to August 2012,326 RSA cases undergoing treatment in Infertility Center of Qilu Hospital were studied retrospectively.Those patients were divided into 2 groups randomly:260 cases in intradermal injection group were administered via bilateral forearm intradermal injections for immunotherapy once 21 days,then the blocking antibody was determined after 2 (23 cases),3 (73 cases),4 (74 cases),5(90 cases) times respectively,while in subcutaneous injection group,the 66 cases were administered via subcutaneous injection once 21 days,the blocking antibody measured after 3 times; In both cases,the blocking antibody was all determined 2 weeks later.The positive rate of blocking antibodies and the rate of successful pregnancy was recorded,and then followed up after the blocking antibody turning positive.Results (1)Positive rate of blocking antibodies:the positive rate of blocking antibodies were 17％ (4/23),58％ (42/73),72％ (53/74) and 84％ (76/90) in the 2,3,4,and 5 times of intradermal injection group,respectively (P ＜ 0.05).In subcutaneous injection group,the positive rate of blocking antibodies was 38 ％ (25/66),which was significantly lower than that in group intradermal injection receiving 3 times immunotherapy (P ＜0.05).(2) The rate of pregnancy:the 176 patients out of 200 patients were pregnant when antibody was positive after immunotherapy,with 71.6％ (126/176)of patients gained successful pregnancy(the length of pregnancy more than 5 months).Conclusions The route and frequency of administration of immunotherapy could influence the positive rate of blocking antibody.The rate of successful pregnancy will be increased after blocking antibody turning positive.

Objective To value the significance of TGFBR2 gene in mediating HepG2 cell proliferation by RNA interference technology. Methods Three kinds of siRNAs targeting TGFBR2 gene were designed, synthesized and transfected into HepG2 cells via lipofetamine2000. Among three kinds of siRNAs, only the one with the most interference efficacy was selected and the correspondent DNA sequence was inserted into plasmid pEGFP-N3. Then the recombinant plasmid of siRNA-pEGFP-N3 was transfected into HepG2 cell and western blot was used to detect the protein level of TGFBR2. Then, TGF-β1 was used to stimulate HepG2 cells with or without siRNA interference and proliferation of HepG2 cells was observed. Results Among these three siRNAs, siRN-1 appeared to be the most effective. After stimulated by 5ng/mL TGF-β1, proliferation of HepG2 cells showed a marked increase in siRNA-1 group compared with blank and siRNA-NC groups (P<0.05). For all that, the proliferation rate was still lower than that in normal HepG2 cell group without TGF-β1 stimulation. Conclusion By silencing TGFBR2 gene, inhibition of TGF-β1 signaling pathway to HepG2 cells could be decreased, thereby enhancing the cell proliferation.

Objective To investigate the therapeutic effects of fluorouracil implants in Stage Ⅲgastric carcinoma patients after radical gastreetomy. Methods The general state of health and cumulative survival of 200 stage Ⅲ gastric carcinoma patients undergone radical gastrectomy from January, 1999 to, December 2002 in the People's Hospital of Zhongshan City were analyzed, in which only 120 patients administrated fluorouracil implants during radical gastreetomy. The therapeutic effects of fluorouracil implants in stage Ⅲ gastric carcinoma patients after radical gastrectomy were observed. Results The differences of weight (P = 0.041), HGB(P =0.024), Plt(P =0.017), CEA(P =0.001), CA19-9(P =0.003) were significant between two groups. The incidence rate of nausea/emesis in group T (28 %) was higher than that in group O(17 %, P = 0.006), and incidence rates of myelosuppression(P =0.81), diarrhea(P =0.72), hepatic function lesion(P =0.97) and renal function lesion(P =0.20) were no significant. The cumulative 5-year survival rate of group T(45 %) was higher than that in group O (15 %, P =0.002). Conclusion Fluorouracil implants can improve the therapeutic effects on gastric carcinoma patients undergone radical gastrectomy.

In order to investigate the inhibitory effects of Endostar (rh-endostatin, YH-16) in combination with radiotherapy on lung adenocarcinoma A549 in mice and the interaction mechanisms of combined therapy, the transplantation tumor models of A549 lung adenocarcinoma were established. When the largest diameter of tumor reached 1.0 cm, all nude mice were randomly divided into 4 groups: Endostar group, radiotherapy group, radiotherapy plus Endostar (combined treatment) group, and control group (n=6 in each group). The largest diameter and the vertical diameter of tumor were measured at different time points. At the 16th day, mice were executed, and the tumors were applied to analysis of rate of tumor cell apoptosis, and the expression levels of basic fibroblast growth factor (bFGF) mRNA were detected by reverse transcription-polymerase chain reaction (RT-PCR) and those of vascular endothelial growth factor (VEGF) by immunohistochemistry. The results demonstrated that the rate of tumor inhibition in combined treatment group was higher than that in other groups. And the rate of tumor cell apoptosis in combined treatment group was also higher than that in other groups. Meanwhile, the levels of bFGF mRNA and VEGF expression in combined treatment group were lower than those in other groups. It was concluded that Endostar obviously enhanced the curative effectiveness of radiotherapy on lung adenocarcinoma A549 in mice. The underlying mechanisms may involve the down-regulation of bFGF mRNA and VEGF expression to inhibit angiogenesis by Endostar and the cooperative effect of Endostar and radiotherapy to synergistically promote tumor cell apoptosis. And Endostar inhibits angiogenesis by down-regulating the expression of bFGF mRNA and VEGF.

Objective To evaluate the feasibility, safety, and clinical outcome in patients with cervical spondylotic radiculopathy underwent cervical nerve root decompression using the anterior percutaneous endoscopic surgery.Methods Eleven subjects consisting of 6 men and 5 women treated from July 2012 to December 2013 were enrolled in the study.Mean age was 42.1 years (range, 27 to 63 years).All were diagnosed to be unilateral single-segment injury involving C3/4 in 1 case, C4/5 in 2 cases, C5/6 in 6 cases and C6/7 in 2 cases.Because of unsatisfactory results 6 week following the non-operative treatment, the patients were operated on using the anterior percutaneous endoscopic osteophyte removal and nerve root decompression.Operation time, postoperative complications, visual analogue scale (VAS) and modified Macnab scale were recorded.Results Operation time was (102.5 ± 21.3) min (range, 80-140 min).Nine patients were followed up for 12 months and no complications were noted.VAS improved significantly at postoperative 3 days and 1, 3, 6, as well as 12 months compared to the preoperative value (P ＜ 0.01).Modified Macnab scale presented great improvement at postoperative 3 and 12 months compared to the preoperative value (P ＜ 0.01).Conclusion The technique is reliable and effective in treatment of cervical spondylotic radiculopathy.

Objective To evaluate the effects of nursing intervention on the beliefs and behavior of early detection of breast cancer. Methods Four communities in Shanghai were selected by convenient sampling process. Then these four communities were randomly assigned to intervention group and control group. One hundred and eighty women who met the criteria of this study were selected from each group by convenient sampling process.Altogether 739 women were recruited. In intervention group,a one-year nursing intervention guided by health belief model was implemented,such as health education seminars,telephone follow in the third,sixth,and ninth months,and flyers of breast health care in the sixth month. Control group only received conventional education. Results After intervention women became aware of breast cancer (B=0.210,P＜0.01),perceived more benefits from attending early breast cancer detection (B=0.105,P＜0.01),and less difficulties in attending the activities of early detection of breast cancer (B=-0.086,P＜0.05). The number of women who performed breast self-examination once per month increased and more women received clinical breast examination (OR=3.0946) and mammogram after intervention (OR=2.746). Conclusion The nursing intervention,guided by health belief model,is helpful to improve women's beliefs and behaviors of breast cancer detection.
