Objective To apply the theory basis for effectively preventing and treating rotavirus infection by studying on specific humoral immune response in children with rotavirus diarrhea. Methods Seventy-five patients of children (diarrhea group ) and 45 controls (control group) were selected. The antigen and specific antibody in plasma and stool were detected by ELISA method;the type of viral gene was confirmed by reverse transcription PCR method;the expression of mRNA in peripheral blood mononuclear cell was measured by fluorescent light quantitation PCR method. Results In diarrhea group, rotavirus G typing to G3 dominated, accounting for 77.3% (58/75), P sub-type to P8 mainly, accounting for 82.7% (62/75). Rotavirus-specific antibody titers of plasma in diarrhea group were significantly higher than those in control group, IgA antibody titers of stool increased significantly, not only higher than that in control group and plasma. The percentage of CD19+ cells in diarrhea group [(30.8 ± 7.9)%] was significantly higher than that in control group [(23.1 ± 7.7 )%] (P = 0.009 ). And the proportion of CD4+ cells decreased significantly (P = 0.005 ), the expression level of IL- 12p40 mRNA in the entire process in diarrhea group was significantly higher than that in control group(P＜ 0.01 ). Conclusion Children with acute rotavirus infection early in the immune response to specific humoral immunity, especially mucosal immune to significantly improve the main features.

BACKGROUND:Finite element contact analysis was performed in premolars of lower mandible with enamelo-dentinal junction defects, which provided biomechanical evidence for the prevention of wedge-shaped defect and occlusion treatment.
OBJECTIVE:To analyze the effects of undermining damage of the enamelo-dentinal junction on the stress distribution of sclerous tissues of dental cervix.
METHODS:Triangle defects were established and models of wedge-shaped defect were designed in mandibular premolar along the enamelo-dentinal junction. The stresses during tightly biting and masticatory movement were simulated. Nonlinear contact analysis was conducted in sclerous tissues of mandibular premolar in the buccal cervical region.
RESULTS AND CONCLUSION:By simulating the stresses during tightly biting and masticatory movement, the stresses were concentrated in the defected regions of mandibular premolar at the enamelo-dentinal junction. With the defect length increased in size, the stress value and the magnitude of the stress field both increased. These indicated that the destruction of enamelo-dentinal junction altered stress distribution in the buccal cervical region. In the clinic, wedge-shaped defect should be fil ed promptly.

Medicinal characteristics, morphologic structurs, chemical constituents, TLC feature and total flavonoid content of wild and cultivated Artemisia rupestris L. were compared. Results showed that they were all similarin both species.

Objective To explore the clinical effect of ozone combined with nifuratel nystatin vaginal soft capsules on the treatment of vaginitis, and to provide the basis for clinical application. Methods 204 patients with vaginitis in our hospital from January 2013 to December 2016 were divided into the observation group (114 cases) and the control group (90 cases) according to the different treatment methods. The control group was treated with nifuratel nystatin vaginal soft capsules, and the observation group was treated with ozone combined with nifuratel nystatin vaginal soft capsules. The clinical efficacy, symptom relief time and adverse reaction were compared between the two groups. Results After treatment, the total effective rate in the observation was 97.37%, which was significantly higher than 85.56% in the control group(P<0.05). The rapid remission rate of the clinical symptoms in the observation group was significantly higher than that in the control group (P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups.Conclusion The effect is significant that ozone combined with nifuratel nystatin vaginal soft capsules is used on the treatment of vaginitis, which can quickly relieve symptoms, and will not significantly increase the adverse reactions, is worthy of application.

[Objective]To assess the safety and clinical result of Osteoset artificial bone and autogenetic bone grafting ccmbined with internal fixation after radical debridement in the treatment of spinal tuberculosis.[Method]From April 2004 to May 2006,24 cases with spinal tuberculosis were treated with radical debridement,Osteoset artificial bone and autogenetic bone grafting combined with internal fixation.Radiographs(X-rays and CTs) were analyzed to access bony fusion and deformity correction.[Result]All the patients acquired satisfactory incision healing without fever.The follow-up period ranged from 6 to 24 months(mean 15 months).There was no recurrence of the disease or loose instrumentation.The average Cobb's angle correction was(15.2??6.7?).The rate of fusion was 95.8% 3 month after operation,while it was 100% 6 month after operation.[Conclusion]Osteoset artificial bone can avoid the complications of donor bone site.The early clinical outcome is satisfying.

Objective To explore the expression of HIF-2? and VEGF in renal cell carcinoma (RCC) and their correlation with angiogenesis and metastasis of renal cell carcinoma. Methods Expression of HIF-2? and VEGF were assessed by immunohistochemical straining in 48 cases of renal cell carcinomas. Results In 48 cases of renal cell carcinomas, positive rate of HIF-2? was 70.8%. Strong expression of HIF-2? was observed in 12 cases, moderate in 10 cases, weak in 12 cases and no expression in 14cases.There was a significant difference in HIF-2? expression between carcinoma tissues and control tissues (P

Objective To investigate the influence of mycophenolate mofetil(MMF) on blood and urine biochemical indica‐tors as well as the expressions of IL‐1 in anti‐glomerular basement membrane(GBM ) nephritis SD rats .Methods The SD rats were randomly divided into control group ,model group and MMF group .And then the models of SD rat anti‐GBM nephritis were estab‐lished by injecting rabbit anti‐SD rat GBM serum antibodies .The urinary protein and blood parameters were detected initially ,1st , 2nd ,3rd and 4th weeks after administration respectively .The expressions of IL‐1 and TGF‐β1 were detected by Elisa Kit and the re‐nal pathological changes were observed by HE and PAS staining .Results After treatment for 4 weeks by MMF ,the 24 h UP ,BUN and SCr levels were lower in MMF group than those of the model group(P<0 .05) .And the expressions of IL‐1 and TGF‐β1 were decreased in MMF group .The results of HE and PAS staining showed that in model group rats ,glomerular tuft morphology was destroyed and inflammatory cell infiltration was observed in the glomeruli .Some glomeruli had cellular crescent formation .Infiltra‐tion of inflammatory cells was also observed in the interstitium .MMF clearly improved these pathological changes overall ,with im‐provements noted in both glomerular and tubular degeneration as well as in the infiltration of inflammatory cells .Conclusion MMF shows certain renal protective effect on anti‐GBM nephritis SD rats .
