Objective To prepare mouse anti-human monoclonal antibodies against B7-H6 and to identify their biological characteristics. Methods The B7-H6 gene was cloned by RT-PCR from a human lung adenocarcinoma cell line ( A549 ) and then subcloned into the eukaryote expression vector pCMV3 to construct the recombinant vector pCMV3-B7-H6. The recombinant vector pCMV3-B7-H6 that was verified with enzyme digestion and gene sequencing was transfected into NIH/3T3 cells by electroporation. BALB/c mice were immunized with the successfully transfected cells named 2H8 through intraperitoneal injection. The monoclonal antibodies against human B7-H6 with the advantages of high affinity and specificity were pre-pared by using hybridoma technology. Western blot assay and flow cytometry analysis were used to identify the specificity of prepared monoclonal antibodies. Results The recombinant eukaryotic expression vector encoding B7-H6 was successfully constructed. Two hybridoma clones that stably secreted monoclonal anti-bodies against B7-H6 were screened out by using flow cytometry analysis and the monoclonal antibodies se-creted by them were belonged to IgG2a isotype. Specific reactions between B7-H6 and the secreted mono-clonal antibodies were confirmed by Western blot assay and flow cytometry analysis. Conclusion The mon-oclonal antibodies which recognized B7-H6 specifically were prepared successfully.

Objective To investigate whether acupuncture can prevent postoperative nauseaand vomiting (PONV)in patients received breast surgery. Methods Two hundred and forty patients were randomly divided into the acupuncture group and the control group. Patients in the acupuncture group were treated at bilateral Hegu (L4) and Neiguan (P6) after surgery. Patients in the control group received no any interventions. The occurrence of postoperative nausea and vomiting, the number of complete remission and the remedial treatment were record ed. Results The incidences of nausea and vomiting in the acupuncture group were lower than those in the control group from 2 h to 6 h post-operation, with less need of remedy treatment (P < 0.05, respectively). Conclusion Acupuncture in preventing nausea and vomiting after breast surgery owns a certain value in the early postoperative (6 h) stage, with effectively reducing the occurrence of postoperative nausea and vomiting.

Objective: To investigate the impact of levosimendan on mortality in patients with severe heart failure (HF) by Meta-analysis. Methods: We search the PubMed, EMBASE and Cochrane Central Registry of cardiovascular disease to identify all randomized impact of levosimendan vs other medications. The document retrieval was from the establishment of each database until 2014-07. The literatures were taken based on Jadad scale standard and the qualified control study was used without dose and time restrictions by Rev Man 5.2 soft ware, and a total of 37 articles with 4470 patients were finally enrolled for Meta-analysis. Results: Compared with controlling medications, levosimendan could decrease the mortality in patients with cardiac disease caused severe HF (RR: 0.85; 95% CI 0.75-0.97;P=0.02), and cardiac surgery caused severe HF (RR: 0.49; 95% CI 0.28-0.85;P=0.01). Compared with dobutamine, levosimendan could reduce the mortality in patients with severe HF (RR: 0.84; 95% CI 0.73-0.99;P=0.02) and severe ischemic HF (RR: 0.85; 95% CI 0.73-0.99;P=0.04). Conclusion: Levosimendan may reduce the mortality in patients with severe HF caused by cardiac disease, cardiac surgery and ischemic cardiac injury.

Objective To discuss the practical significance and clinical therapeutic effects of shoulder arthroscopy technique in the diagnosis and treatment of glenoid labrum injury. Methods In order to have an accurate diagnosis of glenoid labrum injury of the shoulder, X-ray, arthrography, MRI and arthrog-raphy and arthroscopy techniques were used respectively for thirty-six cases of glenoid labrum injury. Under shoulder arthroscopy, the injured glenoid labrum was partially resected in twenty-eight patients affected with single glenoid labrum injury. The injured glenoid labrum of five SLAP cases were treated with debridement under shoulder arthroscopy, and then the affected shoulder was immobilized by zero-degree traction. The injured glenoid labrum of three Bankart cases also underwent debridement under shoulder arthroscopy, and then treated with improved Bristow operation through limited incision. Results After 2-year follow-up, according to the standard criterion of U. S. Michasel Reese Medical Center, the total pain score and the total joint function score were 75 and 25 respectively; the patients' average score was 65 and 20 postoperatively, compared with 35 and 10 preoperatively. The clinical symptoms of all these cases were greatly improved and the unstable symptoms disappeared postoperatively in eight SLAP injury or Bankart injury patients and they all returned their preoperative activities. Conclusion Glenoid labrum is one of the most frequent parts of shoulder joint to be injured. Shoulder arthroscopy is a necessary and effective advanced technique for a definite diagnosis and treatment of glenoid labrum injury. There is some difficulty to carry out operation with arthroscopy and some specific instruments, however, it is necessary for the surgeon to understand and handle the technique.

Objective To investigate the differential expression of synaptophysin(SYN)in the developing rat cochlea,to analyze the relationship between the expression of SYN and auditory functional development,and to explore the source of the adenosine triphosphate(ATP)in the cochlea.Methods The immunofluorescence was applied to observe the differential expression of SYN in the cochlea of SD rats on different days(p1,p5,p10,p14 and p28)after parturition.Results No significant stain was observed in the Kolliker organ or the Corti's organ of P1,P5 and the top turn of the cochlea in P10.The SYN expression was turned on the outer spiral bundle,the inner spiral bundle,and the medial wall of the Deiters' cell of the cochlea in P14,P28 and the second or the third turn of Corti's organ of P10.All the spiral ganglion neurons(SGN)were stained in different aged cochlea.Conclusion The expression of SYN was different during development of rat cochlea.This difference was in favor of the configuration constructed between nerve endings and target cells.It also played a key role in the formation of correct auditory coding during auditory system development.The hair cells and the supporting cells,possible the source of ATP in the cochlea,contained ATP that maybe existed in a non-vesicular form or specific staining of non-SYN.

OBJECTIVE:To observe the efficacy and safety of atorvastatin in the treatment of hypertension with unstable angi-na. METHODS:80 patients with hypertension with unstable angina were randomly divided into control group and treatment group. All patients were given anti-platelet aggregation and other conventional treatment;based on it,control group was orally treated with Amlodipine besylate tablet 5 mg,once a day+Metoprolol tartrate controlled-release tablet 25 mg,twice a day+Isosorbide dini-trate injection 10 ml by intravenous infusion,twice a day;treatment group was additionally treated with Atorvastatin calcium tablet 20 mg,orally,qd. 3 months was a treatment course,and it lasted 6 courses. Clinical efficacy,and systolic blood pressure,diastol-ic blood pressure,angina frequency and duration,changes of TC,TG,LDL,HDL levels before and after treatment and adverse reac-tions in 2 groups were observed. RESULTS:Total effective rate in treatment group was significantly higher than control group,the difference was statistically significant(P<0.05). After treatment,systolic blood pressure and diastolic blood pressure in 2 groups were significantly lower or shorter than before,the difference was statistically significant(P<0.05),however,there was no signifi-cant difference between 2 groups(P>0.05);angina frequency and duration were significantly lower than before,and treatment group was lower than control group,TC,TG and LDL in treatment group were significantly lower than before and control group, HDL was higher than before and control group,the differences were statistically significant(P<0.05),there was no significant dif-ference between before and after treatment in control group(P>0.05). There was no significant difference in the adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Based on the conventional treatment, atorvastatin can effectively reduce the long-term angina frequency and duration of patients with hypertension with unstable angina,improve the ischemia myocardial and reduce the lipid levels with good safety.

Objective: To study whether parental rearing styles of medical students with IAD are related to their mental health, in order to provide foundation for the prevention and control of IAD. Method: Medical students in grade 1 to 4 in Chongqing Medical University were assessed with SCL-90, EMBU, Internet Addiction Disorder Test,and a compare analysis was made for IAD group and non-IAD group. Results: 6.49% subjects can be defined as IAD according to their testing scores of Internet Addiction Disorder Test. The results of EMBU demonstrated that students in IAD group got more punishment, negation and less care or understanding than those in non-IAD group. The results of SCL-90 demonstrated that IAD group got higher scores than non-IAD group. Parental rearing styles of medical students with IAD are related to their mental health. Conclusion: Medical students with IAD got more punishment, negation and less care or understanding,and have lower mental health than those with non-IAD. Negative parental rearing styles of medical students with IAD have bad effects on their development of normal mentality. Parents should pay more attention to their rearing styles.
