Objective To investigate elderly patients with thoracic radiotherapy nausea result after risk factors associated with radiation pneumonitis.Methods The clinical data of a total of 440 cases of cancer patients with chest radiation therapy during January 2010-January 2014 were collected retrospectively.Of them,76 cases of radiation pneumonitis after radiotherapy were compared with other patients.The unconditional Logistic regression analysis was used to analyze the relationship of radiation pneumonitis and different factors including smoking,pulmonary dysfunction,combination with chemotherapy,radiation dose,and radiation sites.Results Elderly incidence of radiation pneumonitis was 17.27％.Multivariate Logistic regression analysis revealed the chi-square value of smoking,pulmonary dysfunction,combined with chemotherapy,radiation dose,and radiation sites was significant correlation (x2 =16.936,19.633,11.531,17.133,10.178,P ＜0.05),and the correlation degree was gradually decreased from pulmonary dysfunction,radiation dose,smoking,combined chemotherapy,to radiation site.Conclusions Elderly patients with thoracic malignancies after radiotherapy had more radiation pneumonitis,which was related to smoking,previous chemotherapy PO2 ＜ 80％,combined with chemotherapy,radiation dose ≥ 55 Gy,and low-lung radiation.The correlation degree was gradually decreased from chemotherapy before PO2 ＜ 80％,the radiation dose ≥55 Gy,smoking,combined chemotherapy,to low-lung radiation.

Objective:To define the effects of SHEN YI,a Chinese herbal formula on ratio of Th1/Th2 cells within immune organs of MRL/lpr mice Methods:MRL/lpr mice were administered daily with the Chinese herbal formula from the age of 12 weeks and both the treatment and control groups were killed at the age of 28 weeks The percentage of CD4 +CD30 -(Th1),CD4 +CD30 +(Th2)cells within thymus and spleen were determined in vitro by FACScan with or without PHA P stimulation The CD4 + T cells selected from splenocytes were stimulated with PHA P, then, RT PCR was performed to detect IL 4/IFN ? mRNA expressed by the selected cells In addition, the ratio of the two cytokines expressed by the CD4 + T cells from the control and treatment groups was calculated respectively Results:CD4 +CD30 + T cells nearly can't be detected within Thymus Without PHA P stimulation, there was no difference in percentage of CD4 +CD30 + T cells between the control and treatment groups After stimulation with PHA P, FACScan showed an increment in the percentage of CD4 +CD30 + T cells both in the control and treatment groups, however, the extent of expansion of CD4 +CD30 + T cells percentage in treatment group was lower than it in the control one RT PCR showed a reduction in the ratio of IL 4/IFN ? mRNA in the treatment group compared to it in the control one Conclusion:The Chinese herbal formula can inhibit Th cells to differentiate into Th2 cells in the spleen under the stimulation of PHA P

Objective To explore the efficacy and safety of conversion from calcineurin inhibitor (CNI) to sirolimus (SRL) as major immunosuppressive therapy in lung transplant recipients.Method Retrospective analyses were conducted for the clinical data of all the patients undergoing lung transplantation in Wuxi People's Hospital between January 2011 and December 2014.Sixteen were given conversion treatment with Sirolimus in the postoperative irnmunosuppressive therapy.We analyzed the opportunity and reasons in the conversion treatment,and the safety,effectiveness and complications of the conversion treatment.Result The follow-up period was 8 to 25 months,and the median time of conversion was 6 months after operation (2-18 months).The indications of conversion concluded:malignant tumor (n =8),renal dysfunction (n =5),lymphangioleiomyomatosis (n =1) and intractable diarrhea caused by CNIs (n =2).Four cases suffered from interstitial pneumonitis associated with Sirolimus and one case suffered from spontaneous pneumothorax,and they all conversed back to CNIs.In those patients,cancer recurrence occurred in 4 cases (of them,there were 3 deaths),and 3 patients developed chronic rejection.Those recipients receiving the conversion treatment due to renal dysfunction showed recovery of renal function to some extent.Conclusion It's effective and safe to converse the immunosuppressive therapy based on Sirolimus.Sirolimus should be reduced or withdrawn when interstitial pneumonitis associated with Sirolimus occurred.

OBJECTIVETo systematically review the clinical efficacy of acupuncture on the patients with low back pain (LBP).

METHODSRandomized controlled trials (RCTs) about pure acupuncture therapy versus other treatments in treating LBP were electronically searched in PubMed, CBM, EMbase, The Cochrane Library, CNKI, VIP and Wanfang Data from January 2004 to May 2014. The observed index on the results were the changed scores of VAS, ODI, JOA and RMDQ. Two reviewers independently screened the literatures according to the inclusion and exclusion criteria, as well as the extracted data, and assessed the methodological quality. The results of Meta-analysis was conducted by RevMan 5.2 software.

RESULTSTen RCTs involved 751 patients were finally included. The results of Meta-analysis indicated that the role of pure acupuncture group in improving the VAS score was better than that of the control group, and the combined effect size was RR = -.32, 95% CI (-1.41, -1.22); Z=27.28, P<0.00001; the role of pure acupuncture group in improving the ODI score was better than that of the control group, and the combined effect size was RR = -5.07, 95% CI (-7.50, -2.65); Z=4.10, P<0.0001; the role of pure acupuncture group on improved JOA score was better than that of the control group and the combined effect size was RR=2.83, 95% CI (2.02, 3.63), Z=6.90, P<0.00001. The role of pure acupuncture group in improving the RMDQ score was better than that of the control group, and the combined effect size was RR = -2.80, 95% CI (-3.49, -2.11), Z=7.95, P<0.00001.

CONCLUSIONThe result of meta-analysis demonstrates that pure acupuncture may have a favorable effect on self-reported pain and functional limitations in LBP patients.

Protein tyrosine phosphatase (PTP) 1B is a potential target for the treatment of diabetes and obesity. We have previously identified the benzoyl sulfathiazole derivative II as a non-competitive PTP1B inhibitor with in vivo insulin sensitizing effects. Preliminary SAR study on this compound series has been carried out herein, and thirteen new compounds have been designed and synthesized. Among them, compound 10 exhibited potent inhibition against human recombinant PTP1B with the IC50 value of 3.97 micromol x L(-1), and is comparable to that of compound II.

6.2 mmol/L) who underwent renal transplantation accepted pravastatin therapy 10 mg once evening for 8 weeks. Total cholesterol(TC),low-density lipoprotein-cholesterol (LDL-C),high-density lipoprotein-cholesterol (HDL-C),triglyceride(TG),endothelin(ET) and nitrous oxide(NO) were measured before and after pravastatin therapy. The endothelium-dependent relaxing function was measured before and post pravastatin therapy by high-resolution ultrasound. Thirty people with normal blood cholesterol accepted same examination as control. Results The level of ET in renal transplantation group was significantly higher than that of control group,and the level of NO in renal transplantation group was significantly lower than that of control group. After 8 week′s therapy,the level of NO rose significantly,and the level of ET,TC,LDL-C,TG decreased significantly. The level of HDL-C increased but there was no significant difference between two groups. Flow-mediated vasodilations were improved after pravastatin therapy,while the level in transplantation group was lower than that of control group. Conclusion Pravastatin is effective in treatment of dyslipidemia after renal transplantation,which can improve the endothelium-dependent vasodilation.
