It had good therapeutic effects in the treatment of nervous system diseases. In recent years, it has also been used in the treatment of diabetes complications. This paper provided an overview on clinical reports about Mongolian medicineErdun-wurile in the treatment of diabetic peripheral neuritis.

Objective · To investigate the gender-related metabolomic differences in human saliva. Methods · The saliva metabolomic profiles of 5 male and 5 female healthy volunteers with matched age, body mass index (BMI), living and tooth-brushing condition were acquired using ultra-high performance liquid chromatography with quadrupole time-of-flight mass spectrometry. Metabolites were identified using publicly accessible databases and further confirmed individually with standard compounds. Both multivariant and univariate statistics were conducted to find inter-gender differences.Results · Forty-eight metabolites in human saliva were identified including 13 amino acids, 6 choline metabolites, 15 carnitines, 4 sphinganine metabolites,7 lysophosphatidylcholine and 3 organic acids. Levels of phenylalanine, acetylcarnitine, propionylcarnitine, butyrylcarnitine, isobutyrylcarnitine,isovalerylcarnitine and sphinganine were higher in the saliva of females than that of males. Conclusion · Rich metabolic information present in human saliva with significant gender diffference which ought to be taken into consideration in study on the metabonomics of saliva.

Objective To compare the clinical efficacy and complications of allogeneic peripheral blood stern cell transplantation (Allo-PBSCT) and immunosuppressive therapy (IST) for severe aplastic anemia(SAA). Methods Twenty-five patients with SAA underwent allogeneic HLA-matched sibling donor PBSCT(n = 12) and IST (n = 13). PBSCT group received conditioning regimen of cyclophosphamido(Cy) in combination with antithymocyte globulin(ATG). IST group received ATG followed by cyclosporine A (CsA).The short-term and long-term effects and complications were investigated. Results The mean time of recovery in the absolute neutrophil count (ANC), platelet and hemoglobin (Hb) in PBSCT group [(13.5±2.3), (23.5±4.1), (82.7±6.1)d, respectively]was shorter than those in IST group [(32.6±3.5), (73.8±6.2), (296.4±12.5)d, respectively]and there were statistical differences between two groups(P<0.05). But the one-year treatment effect between two groups showed no difference (P>0.05). There were no statistical differences in 3-year survival and overall survival rate between two groups (P>0.05). However, statistical difference was observed in overall relapse rate (P<0.05). The common complication in two groups was virus infection including cytomegalovirus (CMV) and varicella zoster virus (VZV), but there was no statistical difference in the incidence of virus infection between them (P>0.05). Conclusions Both allo-PBSCT and IST are effective methods for treating patients with SAA. PBSCT is considered preferentially in clinic, because of its advantages in faster hematopoietic engraftment, lower relapse rate and no increased complication.

Objective To analyze the clinical pathology features of light-chain amyloidosis associated renal disease,and investigate the survival influential factors. Method From January 1998 to March 2009,25 patients with light-chain amyloidosis associated renal disease were reviewed and followed up.Results Of the 25 patients with light-chain amyloidosis associated renal disease,median age was 57(37-69) years old and lamda light-chain predominated (88% ,22/25). Heavy proteinuria and nephrotic syndrome with peripheral edema were typical clinical presentations. Renal biopsy showed that amyloid deposition of light-chain amyloidosis associated renal disease involved the glomeruh mostly, with mesangial area widening. Median survival of all patients was 24.4 months after diagnosis. The estimated 1,2,3 year survival rate was (65 ± 10 )%, (46 ± 12 )% and (15 ± 12 )% respectively. There was significant difference in median survival between the two groups (24.7 months in the group of 14 patients with isolated kidney affected,16.4 months in the group of 11 patients with kidney and other organs involved,P = 0.03). By univariate analysis, kidney associated with other organs amyloidosis and renal dysfunction were relevant to prognosis (P ＜ 0.05) and heart involvement was probably relevant (P = 0.06),whereas sex,age,plasma cell ratio,serum albumin level and hemoglobin level had no relation(P＞ 0.05 ). Multivariate analysis revealed that renal dysfunction at the time of diagnosis was a significant and independent prognostic factor for survival (P ＜0.05). Conclusions Renal dysfunction at the time of diagnosis is the best predictor of survival. The presence of amyloidosis in organs other than the kidney, such as advanced cardiac amyloidosis, predicts a poor survival.

Objective To investigate the tempo?spatial patterns of schistosomiasis in Jiangling County,Hubei Province,so as to identify the risk areas and provide the scientific evidence in following intervention plans for marshland epidemic areas in the stage of transmission control. Methods The schistosomiasis epidemiological data in Jiangling County from 2009 to 2013 to?gether with the related geographical information were collected and analyzed. The tempo?spatial distribution patterns were ana?lyzed by the spatial autocorrelation analysis and spatial clustering analysis. Results The human infection rate was decreased from 2.15%in 2009 to 0.63%in 2013,which was the historically low level. The results of tempo?spatial analysis showed that there were spatial clustering effects in human schistosomiasis infection for each of the years. The values of spatial autocorrelation index Moran’s I were statistically significant. Eighteen and thirty?five clusters were detected by using SatScan and FlexScan soft?ware,respectively. Conclusions From 2009 to 2013,the schistosomiasis endemic situation in Jiangling County presented a decline trend and reached the historical low level. The identified spatial clustering areas should be targeted as the prioritized ar?eas for schistosomiasis control.

AIM: To investigate the effect of exercise stress on chronic cigarette smoking-induced downregulation of expression of large-conductance calcium-activated potassium channel (BK_(Ca)) and voltage-dependent delayed rectifier potassium channel (Kv1.5) in rat bronchial smooth muscle cells. METHODS: Rats were divided into 3 groups: normal control, smoking control and smoking plus exercise training group. The alteration of airway responsiveness and plasma cortisol level were detected, and potassium channel expression and pathological changes in lung tissue were determined with HE staining, immunohistochemistry, in situ hybridization and Western blot techniques. RESULTS: (1) Cigarette smoking induced an increase in airway responsiveness, smoking plus exercise lead to a decrease in airway responsiveness in contrast to smoking control group; (2) Plasma level of cortisol determined immediately after exercise was higher than that determined before exercise; (3) HE staining showed that there was severe chronic pulmonary inflammatory response in smoking control group, which was slight in the smoking plus exercise group; (4) The protein and mRNA expression of BK_(Ca) in cigarette smoking group were less than that in control group in BSMC, the mRNA expression of BK_(Ca) in exercise group were higher than that in smoking group; (5) The protein and mRNA expression of Kv1.5 in smoking group were less than that in control group in BSMC, and expression of Kv1.5 in exercise group was higher than that in smoking group in bronchioli. CONCLUSION: Proper exercise training can increase the expression of potassium channel BK_(Ca) and Kv1.5, and increase the cortisol secretion, which may contribute to the decreasing of airway hyperresponsiveness induced by cigarette smoking.
