This paper report the effects of hyperglucosemia and hypoinsulinemia on Immune system of alloxan diabetic mice. The results showed that the weight of thymus and spleen as well as the YAC-1 cell cleaning rate in the organs (lung, liver, blood) of the diabetic mice were significantly lower than that of the control. The proliferation response to Con A(2.5-20?g/ml) and the production of IL-2 of the lymphocytes were inhibi-ted markedly. When the lymphocytes were suspended in the culture medium containiny insulin, the proliferation response and the production of IL-2 increased markedly. These results suggested that the functions of lymphocytes and their natural killer activity were impaired in diabetic mice. Insulin is one of the important immunoregulation hormones and plays an important role in the regulation of immune system.

Objective To investigate the effect of Salvia miltiorrhiza injection on proliferation , apoptosis and expression of hydroxyproline in human embryonic lung fibroblast cells. Methods TGF-β1 was administered to induce the proliferation in human embryonic lung fibroblast cells; the effect of Salvia miltiorrhiza injection on the number of human embryonic lung fibroblast cells was detected by MTT method; ki67 expression by immunocytochemical method;cell apoptosis by flow cytometry and the expression of hydroxyproline by colorimetry method. Results TGF-β1(0, 2.5, 5, 10, 20, 40 μg/L)could up-regulate cell number of human embryonic lung fibroblast cells in a dose-dependent manner , while the OD value of human embryo lung fibroblasts cells declined pretreated with Salvia miltiorrhiza injection in a dose-dependent manner and Salvia miltiorrhiza injection could induce the apoptosis and down regulated hydroxyproline expression in human embryo lung fibroblasts cells. The results of flow cytometry indicated that cell apoptosis increased after treated with Salvia miltiorrhiza injection when compared with TGF-β1 group (P < 0.05). Meanwhile, Salvia miltiorrhiza injection could down regulate the expression of hydroxyproline (P < 0.01). Conclusions Salvia miltiorrhiza injection can target human embryonic lung fibroblast cells , play a potent role in the airway remodeling through the promotion of its apoptosis and down regulate the expression of hydroxyproline.

Objective To investigate infection rate and susceptibility to antimicrobial agents of Mycoplasma urealyticum and Mycoplasma hominis in the genitourinary tract, and to provide a reference for clinical diagnosis and therapy. Methods Genitourinary secretions were collected with swabs. They were cultured with the diagnostic kit of Mycoplasma (Biomerieux Company) to detect M. urealyticum and M. hominis. Meanwhile the susceptibility of Mycoplasma against 9 antimicrobial agents was tested with the same kit. According to the manual of the kit, the results were read. The data were statistically analyzed with WHONET5.1 and SPSS. Results A total of 1 008 samples were collected, and the positive rate was 77.5%. Among 781 positive cases of Mycoplasma, 572 were M. urealyticum(56.0%), 40 were M. hominis (4.0%), and 169 were M. urealyticum combined with M. hominis (16.7%). The susceptibility rate of M. urealyticum to Doxycycline, Josamycin, Ofloxacin, Erythromycin, Tetracycline, Ciprofloxacin, Azithromycin, Clamycin and Pristinamycin was 89.3%, 95.1%, 17.5%, 64.3%, 84.1%, 14.8%, 77.8%, 90.8% and 96.5%, respectively. The susceptibility rate of M. hominis to the above drugs was 86.0%, 78.9%, 23.2%, 0, 73.2%, 57.1%, 0, 7.7% and 83.9%, respectively. The resistant rate of Mycoplasma to Azithromycin and Clamycin in 2004 was higher than that during the period of 2000 to 2003(P

The in vitro modulation effect of insulin on DNA and IL-2 production of spleen lymphocytes in diabetic mice were studied. The results suggest that the DNA and IL-2 production of the lymphoc-ytes are significantly inhibited in the mice. When suspend the lymphocytes to the culture medium containing insulin, the DNA and IL -2 production of the lymphocytes are remarkably increased. Therefore, insulin is an important immunoregulation hormone.

Objective To monitor the distribution and resistance of enteric pathogenic bacteria in Beijing area to offer the data for guiding epidemiologic study and clinical treatment. Methods Enteric pathogenic bacteria were cultured and identified to spicies, group, and serotype with the biochemical and serologic test. Then, the susceptibility of bacterium to antimicrobial agents were tested. Results Enteric pathogenic bacteria infection occurred with male, children, and youth being prominant. It peaked in June and July. Shigellae spp and Vibrio spp were the main pathogenic bacteria of intestinal tract. There presented difference among the sensitive rates of differential spicies, or groups to antimicrobial agents. Conclusions There are many spicies of enteric pathogenic bacteria causing infective diarrhea in Beijing area. Their distributions are different in sex, age and season. The is resistance rate are different needing surveillance.

Objective To evaluate chest CT features of microscopic polyangiitis(MPA).Methods Clinical data and chest CT images of 66 patients diagnosed as MAP had been collected.Depending on clinical manifestations.the 66 cases were divided into the active group and the stable group.The data of two groups were analyzed by x2 test.Results Forty-three of 66(65.2%)CT images were abnormal including 32 of them in active group and 11 in stable group. In these patients,CT images showed ground glass opacities(53.5%),lung consolidations(23.2%),scattered patchy opacities(44.2%),ground glass opacities and/or lung consolidations(76.7%),reticular opacities(65.1%),honeycomb(14.0%),pleural effusions(48.8%),emphysema(18.6%),and mediastinal adenopathies(58.1%).Lung consolidations,ground glass opacities,scattered patchy opacities,mediastinal adenopathies,and pleural effusion in the active group are more common than that in the stable group(X2=4.479,4.083,4.053,9.697,9.345 respectively,P<0.05).Conclusion Chest CT features of in patients with MPA have difference between active and stable periods.The chest CT scan is a useful tool to diagnose MAP in different periods and guide the treatment.

Objective To amplify the 16S RNA fragments of 7 clinically isolated strains of Brucella spp. by PCR-RFLP technique, so as to provide experimental basis for the studies on diagnostics, genetics and epidemiology of Brucella spp. Methods According to the gene sequence of ATCC 25840 standard strain in GenBank, special primers for the 16S RNA conservative area in the Brucella spp. were designed. DNA extraction and PCR amplification of the 16S RNA fragments were performed with the 7 isolated strains. PCR products were then sequenced and RFLP analysis was conducted with appropriate restricted enzymes to study the homology and the mutation sites in those strains. Meanwhile, the clinical data of infected patients were retrospectively analyzed to evaluate the relationship between the clinical features and genotypes of Brucella infection. Results The amplified target fragments were about 1500bp in length and consistent with what was expected. The sequencing and homology analysis showed a 98.88% homology and 11 mutation sites among the 7 isolated strains. Four genotypes were identified by RFLP. Retrospective analysis of the clinical data indicated that no obvious relationship existed between the genotypes and the clinical features. Conclusions Amplifying 16S RNA fragments by PCR technique is a feasible method to make an early diagnosis of Brucella infection. The 7 clinically isolated strains are different in genotypes and 16S RNA fragment is a highly conservative fragment in bacterial genome with some mutations. The research provides evidence for the genetics and epidemiology of brucellosis.
