Objective To evaluate the protective effect of taurine on renal injury induced by high energy shock wave in rabbits.Methods Twenty rabbits were divided into the experimental (n=10)and the control group (n=10) at random.Both the groups were exposed to 1500 shock waves at 12.75 KV.In the experimental group, taurine (150 mg/kg) was given intravenously during the shock, while normal saline was given in the controls. Malondialdehyde(MDA) and superoxide dismutase(SOD) in serum were measured and the histological changes, the expression of heat shock protein 70(HSP70) in kidney were determined 3 days after the shocks.Results The level of MDA was(2.2±0.4) ,(2.1±0.4)mmol/L, and the level of SOD was (56.4±9.9) ,(55.8±10.1)μU/L respectively in the experimental and the control group before the shock.There was no significant difference between the two groups(P＞0. 05). After the shock, the level of MDA and SOD was (2.7±0.7)mmol/L, (55.3±5.7)μU/L respectively in the experimental group. There was no significant difference(P＞0.05) compared with the level of before the shock's. While in the control group, the level of MDA and SOD was (5. 7±0. 7) mmol/L, (33. 3±3. 5)μU/L respectively.There was significant difference (P＜0.05) compared with the level of before the shock's. The renal tubule scores of the experimental group and the control group after shocks were 7.2±0.8 and 31.8±1.9, respectively. And the HSP70 scores were 25.2±4.1 and 6.4±0.9, respectively. There was significant difference between the two groups (P＜0.05).Conclusions Taurine can effectively protect kidney from injury induced by high energy shock wave in rabbit.The mechanism may be related with its antioxidant capacity and inducing the synthesis of HSP70 in kidney.

Objective To compare the curative effects of intertrochantefie fractures in aged by two operative methods. Methods 85 cases of elderly patients suffered from intertrechanteric fractures were retrospectively ana-lyzed. Out of the 85 cases,45 cases were treated with dynamic hip screw(DHS) and 40 cases were fixed with Gamma nails. The curative effects and complications were compared simultaneously. Results The total excellent rate was 83.5% in 85 patients,the rates of DHS and Gamma nails group were 77. 8% and 90% (X2 = 2. 84, P 0. 05), re-spectively. The operative time (66. 4 ± 19. 4)min in DHS group were less than the Gamma nail group (875 ± 25.5) rain (t=2. 451 ,P < 0. 05), but the length of surgical incision (19. 6± 5. 1)cm greater than the Gamma nail group (10. 3 ± 4. 7) cm(t = 2. 501, P < 0. 05). The complications of DHS group (11.1%) were significanfly higher than that of Gamma nail group(2. 5%) (X2 =3.94,P<0. 05). Conclusion As long as the physical condition can toler-ate,surgery recommend the use of DHS and Gamma nail surgical techniques in aged patients with intertrechanteric fractures.

Purpose:To determine the efficacy and toxicity of gemcitabine plus cisplatin in anthracyclin- and taxane-pretreated patients with advanced breast cancer. Methods:Chemo-resistance was defined as no response while rece iving first-line and/or second-line chemotherapy. Patients with advanced and c hemo-resistant breast cancer, which was confirmed histologically, received gemc itabine 1,000 mg/m 2 on d1, 8 and cisplatin 25 mg/m 2 on d1-3, every 3 weeks.2 cycles were delivered at least. Results:30 female patients were enrolled in this trial. All pat ients were evaluable for response and toxicity. The median age was 46 years (ran ge, 34-58 years). After 2-4 (median, 3) cycles of chemotherapy, overall object ive response was 50.0%, with 5 CRs (Complete response 16.7%) and 10 PRs (Partial response 33.3%). Stable disease was seen in 13 patients (43.3%), and disease pr ogression in 2 patiens (6.7%). Toxicities included myelosuppression and gastroin testinal reaction mainly. Grade Ⅲ-Ⅳ toxicites developed in 50% patients. Ther e were no treat-related deaths. The median follow-up time was 12.5 (range: 2- 48) months. Median overall survival was 14 months, and median time to progressio n was 10 months. Conclusions:These data indicate that the combination of gemcita bine and cisplatin is an effective treatment for heavily pretreated breast cance r patients with manageable toxicity.

The diagnostic evidence on clinical diseases and theoretic basis of moving cupping therapy were ex- plored in the paper. By the observation of the local reaction, such as skin appearance and color, the affected location, duration of sickness and nature of disease were judged. Different moving cupping methods were selected for different disorders. It was discovered that the property of syndromes should be recognized by the palpation on skin and muscle in the moving cupping therapy so that the pathogenesis and treating principle could be carefully determined. The moving cupping therapy is the important component of body surface therapy. Skin reaction observation and syndrome differentiation is the essential guidance of the moving cupping therapy.

Objective To investigate the clinical efficacy of mallet needle plus acupuncture in treating stiff neck. Method Eighty patients with stiff neck were randomly allocated to treatment and control groups, 40 cases each. The treatment group received mallet needle therapy plus acupuncture and the control group, acupuncture alone, for three consecutive days. In the two groups, the Pain Rating Index (PRI) score and the Visual Analogue Scale (VAS) score were recorded before and after treatment and the clinical therapeutic effects were evaluated after treatment. Result The PRI score and the VAS score decreased in both groups after treatment compared with before (P<0.05) and decreased more in the treatment group than in the control group at the end of treatment (P<0.05). The total efficacy rate was 95.0% in the treatment group and 87.5% in the control group; there was a statistically significant difference between the two groups (P<0.05). Conclusion Mallet needle therapy plus acupuncture is more effective than acupuncture alone in treating stiff neck.

Objective To investigate the genetic stability, immunogenicity and protective efficacy of AdC68-rab. gp, a novel rabies vaccine based on the replication-defective chimpanzee adenoviral vector AdC68-ept. Methods The recombinant adenovirus AdC68-rab. gp expressing the glycoprotein of rabies vi-rus ERA strain was constructed. Genomes of the AdC68-rab. gp of different generations were extracted and analyzed. HEK293 and Huh7 cells were infected with the AdC68-rab. gp of different generations. ICR mice were immunized with the AdC68-rab. gp and blood samples were collected 4 weeks or 6 months after immuni-zation. Rapid fluorescent focus inhibition test ( RFFIT) was performed to detect the neutralizing antibody against rabies virus in mice serum samples. ICR mice were challenged with lethal dose of rabies virus 4 weeks after the immunization with AdC68-rab. gp to evaluate the protective efficacy of AdC68-rab. gp. Re-sults The genome of AdC68-rab. gp was stable after 15 passages, which was identical to that of the 5th and 1st generations. High levels of neutralizing antibody against rabies virus in serum samples were detected in mice immunized with AdC68-rab. gp and maintained for a long period of time. Immunization mice with one dose of AdC68-rab. gp could protect all mice from the lethal dose challenge of rabies virus. Conclusion The novel AdC68-rab. gp was characterized by good genetic stability and ideal protective effi-cacy. The adenoviral vector based vaccine could be further developed as a potential candidate for the substi-tute of current rabies vaccine.

Objective To explore the clinical features, diagnosis, and treatment of neonatal necrotizing pneumonia. Methods The clinical data of two cases of neonatal necrotizing pneumonia were retrospectively analyzed. The clinical features, diagnosis, and treatment of neonatal necrotizing pneumonia in literatures were summarized. Results Two cases were diagnosed of community-acquired Staphylococcus aureus necrotizing pneumonia and had the onset with fever. The chest X-ray showed exudative change with cystic shadow. The chest CT showed multiple cavity changes. The sputum and blood cultures were positive for Staphylococcus aureus. Both of them were effectively treated by vancomycin. The imaging was improved during the follow-up. Searching the database, 4 related literatures were being found, and there were totally 7 cases of neonatal necrotizing pneumonia including current 2 cases. The main features were as follows: The pathogenic bacteria in all cases include Staphylococcus aureus. One case was combined with pseudomonas aeruginosa. Six cases were community-acquired infections. All of them were non-immune deficiency newborn. Six cases were primary necrotizing pneumonia. Six cases were unilateral lung involvement. Five cases got fever, 5 cases had septicemia, 3 cases had pleural effusion, 2 cases had aerothorax, one case had bronchial chest and 2 cases had extrapulmonary infection. The C-reactive protein was increased in all cases. Three cases need mechanical ventilation. Six cases had a good prognosis. Conclusions The main pathogenic bacterium in neonatal necrotizing pneumonia was Staphylococcus aureus. The diagnosis was mainly depends on the typical imaging and pathogenic examination. The treatment is mainly the use of antibiotic for gram positive cocci.

Objective To prepare and screen out monoclonal antibodies against the receptor bind-ing domain (RBD) of Middle East respiratory syndrome coronavirus ( MERS-CoV) spike ( S) protein in mice. Methods The RBD of MERS-CoV S protein expressed in the insect-baculovirus system was purified and then used to immunize the female BALB/ c mice. The spleen cells collected from the mice were fused with myeloma Sp2 / 0 cells. The positive hybridoma cells were obtained by using limited dilution method. Enzyme-linked immunosorbent assay ( ELISA), Western blot assay and neutralization test based on the MERS-CoV pseudovirus were performed for further screening and identification. Results Twelve strains of hybridoma cells that produced the monoclonal antibodies against RBD of MERS-CoV S protein were screened out. All of the 12 monoclonal antibodies (McAbs) could have specific reaction with the RBD of MERS-CoV S protein as indicated by the results of ELISA. Of the 12 McAbs, two were identified as the immunoglobulin M (IgM) isotype and the rest were IgG1 isotype by using double antibodies sandwich ELISA. Four McAbs including 1F1, 2E4, 3C3 and 3E6 were identified as having neutralizing activity by the neutralization test based on MERS-CoV pseudovirus. Results of the Western blot assay showed that the four McAbs (1F1, 2E4, 3C3 and 3E6) could have specific reaction with the RBD of MERS-CoV S protein, but no cross-reac-tion with that of SARS-CoV S protein. Conclusion Twelve mouse-derived McAbs against the RBD of MERS-CoV S protein were obtained. The prepared hybridoma cells showed the characteristics of high speci-ficity and stability in antibody secretion. Four out of the 12 McAbs were proved to have neutralizing activity.

Objective To evaluate the effects of exogenous adenovirus-mediated gene transfer of human apM1 gene (Ad-apM1) on malonaldehyde (MAD) and superoxide dismutase (SOD) levels in human umbilical vein endothelial cells (HUVEC). Methods HUVEC proliferation was measured by MTT after infection by AdapM1. Adiponetin protein level in cell culture medium of HUVEC cells infected with Ad-apM1 was detected by double antibody sandwich ELISA. The levels of MAD and SOD were measured by chromatometry. Results MTT assay showed that Ad-apMl had no effect on HUVEC proliferation. Human adiponectin protein levels in cell culture medium significantly increased after HUVEC was infected with Ad-apM1 for 24, 48, and 72 h, along with decreased MAD and increased SOD ( all P<0.05 ). MAD levels markedly increased and SOD levels decreased after HUVEC were incubated with 100 μmol/L H2O2 for 6, 12, and 24 h, and these reactions were reversed by AdapM1 transfection (all P<0.05 ). Conclusions HUVEC infected with Ad-apM1 effectively secrete human adiponectin. Ad-apM1 exerts antioxidation effect and antagonizes H2O2 -induced endothelial injury.
