BACKGROUND:More than 50% of patients with diabetes are accompanied by osteoporosis. Exercise is the main method to treat diabetes, but whether it has an impact on diabetes osteoporosis is unclear.
OBJECTIVE:To analyze the different exercise intensities and changes in bone mineral density in type 2 diabetic rat models.
METHODS:Forty rats were randomly divided into model group and low-, medium-and high-intensity exercise groups. Al rats received intraperitoneal injection of streptozotocin to establish models of type 2 diabetes. Rats in the low-, medium-and high-intensity exercise groups did treadmil training at 10, 20, 30 m/min, 1 hour per day, 6 daysas a cycle. They had a rest for 1 day after each cycle, for 8 consecutive cycles. Rats in the model group did not do any exercise.
RESULTS AND CONCLUSION:Compared with the model group, the weight of rats was decreased; blood glucose levels were reduced;osteocalcin and serum calcium levels and biomechanical indexes of femur increased; serum phosphorus and alkaline phosphatase decreased in the low-, medium-and high-intensity exercise groups. Bone mineral density increased in the medium-and high-intensityexercise groups. These findings confirmed that different exercise intensitieshavea certain influence on bone mineral density and bone metabolism in type 2 diabetic rat models. When using a method of treating movement, proper physical exercise can increase serum osteocalcin content, improve bone metabolism, prevent diabetic osteoporosis, and have a high clinical value.

Results Totally 146 patients with chronic cough were diaguosed according to the diagnostic routine based on the guideline on diagnosis and treatment of chronic cough established by Chinese Medical Association, which included medical history, medical examination, X-ray or CT of paranasal sinus or chest, lung function, gastroscope, sputum cytology classification. The final diagnosis was made based on clinical manifestation examination findings and a positive response to therapy. Conclusion The cause of chronic cough was defined in 93.2% of the patients, and multiple causes: Cough variant asthma (n = 45,30.3%), postnasal drip syndrome,PNDs (n = 27, 18.5%), gastroesophageal reflux cough(n = 21,14.4%), post infection cough(n = 16,10.9%), ensinophilic bronchitis(n = 13, 8.9%), drug induced cough(n = 10,6.8%), unidentified cough(n = 10,6.8%). Conclusion Complex etiology of chronic cough,be specific therapeutic effect,and its clear cause is the key to treatment.

BACKGROUND: Hematic protective has arisen widely attention in China and abroad due to the serious blood contamination and transfusion related diseases.OBJECTIVE: To observe hematic protective effect of hypertonic solution chloride hydroxyethy140 injection (HSH) on acute hypervolemic hemodilution (AHH) in maxilla Lefort Ⅰ osteotomy.METHODS: Totally 40 patients were randomly divided into the experimental and control groups, with 20 patients in each group. All patients were operated under tracheal intubation general anesthesia, in the experimental group, 4 Ml/kg HSH was infused with speed of 10 Ml/min, and the infusion was finished within 30 minutes. There was no treatment in the control group. Blood routine examination (including hematocrit, hemoglobin, blood platelets count) and routine coagulation test (including platelet, partial thromboplastin time, fibrinogen) was performed at the points of before AHH (T_0), at the end of AHH (T_1), 30 min after AHH (T_2),60 min after AHH (T_3), 3 hours after AHH (T_4), 1 day after operation (T_5), and 3 days after operation (T_6), respectively.Simultaneously, the capacities of blood transfusion, liquor transfusion, hemorrhage and urine during operation was recorded. RESULTS AND CONCLUSION: All the patients were included in the final analysis. Compared to the control group, the capacity of blood transfusion in the experimental group was smaller than that of the control group (P<0.05), with greater urine volume (P<0.05). However, the differences of liquor transfusion and hemorrhage had no significance (P>0.05). After controlled hypotension,the heart rates of patients at T_2 and T_3 were obvious increased than that of T_1 (P<0.05), the systolic pressure, diastolic pressure,and mean arterial pressure were significantly decreased (P<0.05). At T_1, T_2 and T_3 points, the heart rates of patients in the experimental group were greater than that of the control group (P<0.05). The systolic pressure, diastolic pressure, and mean arterial pressure had no dramatically differences between two groups (P>0.05). After AHH, the hematocrit and hemoglobin were obviously decreased in the experimental group at T_1, T_2, T_3 and T_4 points (P<0.05), with more blood platelets count and prolonged partial thromboplastin time (P<0.05). Compared to the control group, the Na~+, Cl~-was increased in the experimental group at T_1 and T_2 points (P<0.05), with greater hematocrit and hemoglobin at the T_5 and T_6 points (P<0.05). The results demonstrated that HSH can decrease or avoid transfusing blood in maxilla Lefort Ⅰ osteotomy.

Objective　To investigate the direct antitumor effect of several surface molecules of Bifidobacterium bifidum 1101 such as whole peptidoglycan (WPG), lipoteichoic acid (LTA), and polysaccharides (PS) on human colonic adenocarcinoma cell line LoVo. Methods　MTT assay and flow cytometry (FCM) were used to evaluate the effect of Bifidobacterial surface molecules on the growth of LoVo cells. Morphological study, fluorescent polarimetry and differentiation-specific enzyme analysis were used to determine whether LTA treatment could induce the differentiation of the cells. Results　LTA but not WPG or PS significantly inhibited the proliferation of LoVo cells in a dose and time dependent manner. Cell cycle analysis by FCM revealed that LTA induced changes in cycle distribution resulting in G0/G1 phase commitment. Morphological alterations observed by light and electron microscopy indicated maturity of cytoplasm and nucleus following treatment by 50μg/ml of LTA. Membrane fluidity was also altered, and intestinal alkaline phosphatase specific for the differentiation of LoVo cells roused dramatically during culture in LTA. It was further found that LTA elevated ［Ca2+］i which resulted from Ca2+ influx instead of the release of stored calcium. Conclusion　These observations indicated that LTA was able to inhibit the growth of LoVo cells and induce the differentiation of the cells. Calcium influx may play an important role in this process.

ObjectiveTo evaluate the role of serum IgM, IgG and IgA anticardiolipin antibody (ACA) isotypes in the diagnosis of systemic lupus erythematosus (SLE), and their association with lupus nephritis (LN) in children.Methods One hundred and sixteen hospitalized SLE pediatric patients were selected between April 2005 and October 2013. The clinical data were collected and analyzed.Results There were 20 males and 96 females among 116 SLE patients. The positive rate of ACA-IgG, ACA-IgM and ACA-IgA was 37.1%, 35.3%, 26.7% respectively, without signiifcant difference between each other (P>0.05). Among 116 SLE patients, 75 cases had LN and 41 cases had no LN. The positive rates of ACA-IgM and ACA-IgA were not sig-niifcantly different between cases with and without LN (P>0.05). Cases with LN (42.7%) had higher ACA-IgG positive rate than cases without LN (22.0%) (P=0.026). The occurrence of LN and the positive rate of ACA isotypes were not signiifcantly different between genders (P>0.05).Conclusions The different isotypes of ACA have the same signiifcance in the diagnosis of SLE. The detection of ACA-IgG helps diagnose the LN complicated with SLE.
