METHODS: Ninety-six SD rats were divided into six groups at random (n=16 in each group): NS group, HCl group, LPS group, NS+Dex group, HCl+Dex group and LPS+Dex group. Every group was divided into two subgroups: the bronchoalveolar lavage (BAL) subgroup and no bronchoalveolar lavage (NBAL) subgroup. The total leukocytes, PMN%, macrophage%, lymphocyte%, total protein in BALF and the wet/dry of the lung weight were measured. The concentrations of TNF-?, IL-1?, IL-4 and IL-10 in serum and BALF in every group were compared. RESULTS: (1) In the groups of LPS and HCl, the total leukocytes, PMN numbers, the protein concentration in the BALF and W/D were higher than those in control group (P

Purpose To investigate the clinicopathologic changes of the lung epithelial tumor with epithelioid granuloma. Methods E-leven cases of lung malignant tumor with epithelial epithelioid granuloma reaction were studied according to the histological changes of lung epithelial tumor, immunophenotype, acid-fast staining, and tuberculosis PCR test results combined with follow-up data. Results The mean age was 62. 3 years, and male to female ratio was 10∶ 1. The main clinical manifestations displayed a cough, chest pain, fever and hemoptysis or bloody sputum. Nine cases were malignant tumors, tuberculosis or inflammatory lesions was 1 case each in pre-vious surgery. The tumor with epithelioid granuloma formation of the 11 cases displayed in the same site ( mixed) . The histopathologic changes of the lesions showed a epithelioid or typical tuberculous granulomas formation, including 4 cases of adenocarcinoma, 5 cases of squamous cell carcinoma and 2 cases of neuroendocrine tumors. The acid-fast bacilli staining was positive in 3 cases;6 cases were positive for PCR detection of mycobacterium tuberculosis. 5 patients died within 2 years due to various causes. Conclusions The lung epithelial tumors with epithelioid granuloma is more commonly found in the middle-aged, The signs and symptoms of the patients are similar to primary epithelial malignant tumors of the lung . The biological behavior was progressive with poor prognosis. The diagnosis of the lesions depends on pathological examination. It is very important to pay more attention to the pathological examination, especially in lung puncture samples, and the differential diagnosis for a definate diagnosis and treatment.

BACKGROUND:Stem celltherapy for renal ischemia-reperfusion injury has been the hot topics for many scholars. Its mechanism is very complex, which could not be explained by simple mechanism of stem cells differentiation. It is the result involving a variety of mechanisms. OBJECTIVE:To investigate the influence on immune cells during the bone marrow mesenchymal stem celltherapy for renal ischemia-reperfusion injury, then to preliminary summarize the immune regulation mechanism of bone marrow mesenchymal stem celltherapy for renal ischemia-reperfusion injury. METHODS:First, we established a model of renal ischemia-reperfusion injury in rats and, cultured and purified rat bone marrow mesenchymal stem cells in vitro. Then, the bone marrow mesenchymal stem cells were transplanted into the rat models. Using flow cytometry detection technology, we analyzed the proportion of CD4+CD25+regulatory T cells of rat spleen cells, discussed the effects on immune cells during the bone marrow mesenchymal stem celltherapy for renal ischemia-reperfusion injury, and then transferred the rat’s spleen cells to the nude mice which were subjected to renal renal ischemia-reperfusion injury. Renal function and renal histological changes of nude mice were assessed. RESULTS AND CONCLUSION:The bone marrow mesenchymal stem celltransplantation could significantly inhibit the decrease of CD4+CD25+regulatory T cellof spleen cells in rats with renal ischemia-reperfusion injury. The transplantation of spleen cells from the above-mentioned rats to nude mice could obviously protect nude mice from renal ischemia-reperfusion injury, characterized by lower serum creatinine, blood urea nitrogen and renal tubule pathologic damage score. Therefore, bone marrow mesenchymal stem cells have protective effects on renal ischemia-reperfusion injury by regulating the immune system.

BACKGROUND:After entering the aging society, improving the balance function to prevent fals and reduce incidence of fractures in the elderly has received widespread attentions in al aspects. OBJECTIVE: To design a training program for the elderly, involving static stretching and strength exercise of lower limb, in order to study the combined effect on the balance function of the elderly. METHODS: Static stretching and strength training of the lower limbs were carried out in 28 elderly persons who met the inclusion criteria for 3 months, three times a week, once for 60 minutes. Before and after exercise training, the static balance ability with foot standing, eyes open and eyes closed was evaluated using the PRO-KIN balance instrument; the dynamic balance ability and lower limb strength were evaluated using treadmil test with eyes closed and chair-stand test. Evaluation results before and after exercise were compared and anayzed. RESULTS AND CONCLUSION:In the eyes open state, the average X-axis coordinate and exercise-induced elipse area at the center of pressure were significant different before and after exercise (P < 0.01); the mean velocities at the left and right direction were of significant difference before and after exercise (P < 0.05); the results of treadmil test with eyes closed and chair-stand test also presented very significant differences before and after exercise (P < 0.01). Static stretching combined with lower limb strength exercise can effectively improve the balance function and lower limb strength of the elderly, which can be used as an effective exercise way to prevent the fals in the elderly.

Objective To investigate the relationship between vaspin,Apelin,leptin and polycystic ovary syndrome.Methods We determined the serum vaspin,Apelin and leptin levels of 40 cases of PCOS patients and 30 cases of control group,and divided the PCOS group into three subgroups (normal weight,overweight and obesity) according to WHO criteria for obesity.Then we compared the serum vaspin,Apelin and leptin levels in PCOS and control group,and the differences in body weight index (body mass index,BMI) in women with polycystic ovary syndrome,and analyzed roles of adipokine vaspin,Apelin and leptin in the pathogenesis of PCOS.Results In PCOS patients adipokine vaspin,Apelin,leptin,insulin resistance index (Homeostasis model assessment for insulin index in resistence,HOMA-IR),fasting insulin (INS) and blood glucose,blood lipid were higher than those of the control group and increased with the increase of body mass index (BMI),and three kinds of adipokines and PCOS patients with HOMA-IR were positively correlated,there were statistically significant differences (P ＜ 0.05).Conclusion The results of vaspin,Apelin and leptin may be involved in the occurrence of PCOS.

Objective To evaluate the diagnostic value of sonographic score in the diagnosis of salivary gland involvement in patients with Sj(o)gren's syndrome(SS). Methods One hundred and three cases (44 cases of SS group and 59 cases of control group) were involved in the study. Parotid and submandibular glands of all the cases were examined by a doctor unawaring of the clinical information. All the off-line images were scored by two doctors seperately. The best threshold and the according diagnostic efficiency were determined by statistical analysis. Results The Kappa coefficient between the two doctors was 0.80.The parotid score,submandibular score and total score of SS group were significantly higher than those of the control group (5.79 ± 2.40 vs 0.46 ± 0.97,5.93 ± 1.58 vs 1.32 ± 1.84,11.64 ± 3.27 vs 1.78 ± 2.33,respectively). According to the ROC curve for the parotid score, submandibular score and total score, the area under the curve were 0.98,0.95,0.99, respectively. The best diagnostic threshold for total score was 8 and under this threshold, the diagnostic sensitivity, specificity, positive and negative predictive values were 93%, 97%, 95%, 95%, respectively. Conclusions The sonographic score including both parotid and submandibular glands is a reliable method with high reproductivity and diagnostic accuracy in the diagnosis of SS salivary gland involvement.

BACKGROUND:Disruption of biological rhythms(circadian rhythms)is a typical problem associated with aging.Maintaining the normal function of biological rhythms may be a promising anti-aging strategy.Expression of nuclear factor erthroid 2-related factor 2(Nrf2)is biologically regulated.The glycogen synthase kinase 3(GSK3)system represents a"regulatory valve"that controls subtle oscillations in Nrf2 levels.Circadian changes in the transcript levels of antioxidant genes can influence the response of organisms to oxidative stress.However,the specific molecular mechanism of GSK3/Nrf2 in regulating organismal aging is still puzzling. OBJECTIVE:To search for the general pattern of GSK3/Nrf2-regulated biological rhythms in organismal aging by reviewing the literature in this field. METHODS:The bibliographic method was used to search,review and screen the relevant literature using the keywords of"glycogen synthase kinase 3,nuclear factor erthroid 2-related factor 2,biorhythms and aging"to lay a theoretical foundation for the analysis of the whole paper.Comparative analysis method,through reading and analyzing the obtained literature,was performed to compare the similarities and differences between the literature,thereby providing reasonable theoretical support for the argument.Further comparative analysis of the literature was conducted to clarify the relationship between the relevant indicators as well as the ideas for analysis throughout the text. RESULTS AND CONCLUSION:GSK3 can indirectly regulate Nrf2 expression through the regulation of rhythm genes.GSK3 and Nrf2 are components of anti-aging programs and are associated with biological rhythms.In addition,GSK3/Nrf2 is involved in several metabolic pathways,including those associated with age-related diseases(type 2 diabetes and cancer)and neurodegenerative diseases.
