Objective To identify the potential DNA vaccine candidate which can induce the protective immune response to Toxoplasma gondii by inoculating mice with plasmid DNAs encoding three different forms of P30 antigen (membranous secretory,and intracellular). Methods Three forms of recombinant plasmid: pcDNA3 P30Mb(contain the whole P30 gene sequence,including the gene encoding signal peptide and hydrophobic tail),pcDNA3 P30Se(contain the whole P30 gene sequence, without the gene encoding hydrophobic tail) and pcDNA3 P30In(contain the whole P30 gene sequence,without the gene encoding signal peptide) were constructed by PCR and subcloning technique. The mice were immunized with different forms of recombinant plasmids and IgG antibodies in the mice were detected by ELISA and Western blotting. Results Three forms of expression recombinant plasmid of Toxoplasma gondii P30 gene were successfully constructed. The P30 inserts were identified by restrictive enzyme digestion and sequencing. ELISA and Western blotting analysis demonstrated that specific IgG antibody could be induced in three immunized groups, but there was some difference in appearence time and intensity of IgG.Conclusion Genetically immunization of mice with the recombinant plasmids could elicit specific IgG antibodies. In respect to IgG response, the immune efficiency of the three forms of recombinant plasmids was different at the beginning (2 wk),but 4 wk later approximately same.

Objective To report the clinical effects of repairing skin defects in hand by reversed neu- ro-veno-fasciocutaneous flaps based on the superficial branches of radial nerve.Methods Eleven cases with soft tissue defects around the wrist and the dorsum of the hand were treated with superficial branches of radial nerve-cephalic vein neuro-veno-fasciocutaneous flaps.Results The flaps totally survived in the 9 cases,the others were small distal necrosis.Follow-up survey in the(6-48)months after the oporation showed the appear- ante and function were satisfactory.Conclusion Superficial branches of radial nerve neurofasciocutaneous flap is well supplied with blood and easy to perform.It is the ideal flap to repair the skin defects of the first finger web,radial palm and dorsum of hand.

Chinese Center for Disease Control and Prevention published three confirmed novel H 7N9 avain influenza virus in-fection cases on March 31 ,2013 .The disease then spread across China and caused extremely high morbility and mortality , which trig-gered extensive attention .These cases were caused by a novel H 7N9 avian influenza virus which was highly mutable .Once the virus a-dapted to human respiratory epithelium receptors , a pandemic outbreak would occur immediately .This article summerizes the research progress on the H7N9 avain influenza, including epidemiologic characteristics , etiology features, clinical manifestation, detection tech-niques as well as theraputic and prevention strategy .

Objective To compare the effectiveness and safety of ultra-early (< 24 h)and delayed (≥ 24 h ) endovascular embolization of ruptured intracranial aneurysms with systematic review. Methods PubMed,Embase,the Cochrane Library,VIP,Wanfang Data,and China National Knowledge Internet (CNKI)were retrieved according to inclusion,exclusion criteria and retrieval strategies,and the clinical literature of ultra-early and delayed endovascular embolization for the treatment of ruptured intracranial aneurysms were obtained. The Review Manager 5. 3 software was used to conduct Meta-analysis for good prognosis rate,postoperative mortality,and postoperative rebleeding rate. Results A total of 10 articles were included,9 of them were retrospective control studies and 1 was prospective control study. A total of 2 021 patients were enrolled,including 970 patients treated with ultra-early treatment;1 051 patients treated with delayed treatment. There was significant difference in the good prognosis rate (OR,2. 67,95% CI 2. 07 -3. 44,P < 0. 01)and the postoperative rebleeding rate (OR,0. 23,95% CI 0. 11 -0. 47)between the ultra - early embolization group and the delayed embolization group (all P < 0. 01). There were no significant difference in the mortality between the two groups (OR,0. 76,95% CI 0. 51 -1. 13,P = 0. 17). The subgroup analysis showed that there were significant differences in the good prognosis rate in the ultra-early group compared with the early group (< 3 d,OR,1. 98,95% CI 1. 33 -2. 95)and the middle and late group (≥3 d,OR,4. 66,95% CI 2. 21 -9. 81,all P < 0. 01). Conclusion Compared with the delayed group, ultra-early embolization of ruptured intracranial aneurysms may improve the good prognosis rate,reduce the rebleeding rate,and not increase the mortality after procedure at the same time. However,more high quality and large sample randomized controlled trials are needed to confirm them.

Objective To evaluate the efficacy of jaw thrust device in the upper airway obstruction. Methods Thirty-five ASA Ⅰ or Ⅱ patients aged 18-64 yr with body mass index < 30 kg/m~2 undergoing elective surgery under general anesthesia were included in this study. The anesthesia face mask was placed and held tightly by 4 straps of JTD and connected to the anesthesia machine. Anesthesia was induced with midazolam, propefol, fentanyl and atracurium. When muscle relaxation was achieved, tracheal intubation was not performed. The airway obstruction was assessed by airway peak pressure and stridor score (breathing sounds detected by auscultation over the trachea). And then tracheal intubation was performed, and the patients were mechanically ventilated. Results There was no significant difference in airway pressure and stridor scores between JTD and jaw thrust maneuver. Conclusion JTD can effectively lift the jaw and improve the upper airway obstruction.

Objective To summarize the nursing experience of combination therapy of highly agglutinative staphylococcin (HASL) with cisplatin for patients with malignant pleural effusions. Methods After fully draining of pleural fluid in 62 cases with malignant pleural effusion through pleural puncture through central venous catheters and simply suction bottles, we injected HASL and cisplatin into the patients' pleural cavities. During the therapeutic process, firstly, we drained the pleural fluid fully before injection, secondly, we directed the patients to cooperate well and alter the positions properly, and thirdly, we closely observed the patients' condition and adverse reactions. Results 54 of 62 cases were effective after the therapies. The effective rate was 87.1%.Conclusions In order to achieve a satisfled curative effect and reduce the adverse reactions, we need the cooperation of the patients, fully draining of the pleural fluid before injection and proper alternation of the patients' positions during the treatment process.

Objective To observe the protective effects of enalapril on the long-term functions of the allograft in renal transplant recipients. Methods Twenty renal transplant recipients with ~survival time over one year, normal renal functions of the allograft and urine TGF-?_1 levels being more than ~250.0 pg/mg.Cr took enalapril every day for at least one year. Twenty-three recipients under the same conditions who did not receive enalapril served as control group. Three years later renal ~dysfunction cases, loss of creatinine clearance rate (Ccr) and TGF-?_1 levels in blood and urine were compared between the two groups. The changes in the expression of TGF-?_1mRNA in renal biopsy specimens were compared before and one year after enalapril therapy. Side-effects of enalapril were ~investigated in all patients in enalapril-treated group. Results Three years later, the number of renal dysfunction cases was less, the loss of Ccr was less and the level of urine TGF-?_1 was lower in ~enalapril -reated group than those in control group with the differences being significant (P~0.05 ). One year after enalapril therapy TGF-?_1mRNA expression was significantly decreased in renal biopsy specimens (P
