Objective To investigate the effects of notoginseng and guiding medicinals mediated notoginseng for improving the renal inter stitial fibrosis in rats with chronic kidney-disease(CKD)by regulating TGF-β signaling pathway.Methods A total of 100 male SD rats were randomly divided into five groups:normal group(NOR,n =20),model group(CKD,n =20),radix notogin-seng group(RN,n =20),radix notoginseng plus platycodi group (RNP) and radix notoginseng plus cinnamon group (RNC,n =20).Except for the NOR group,the CKD rat model in other groups was established by adenine gavage.After modeling,the NOR group and CKD group were given the same volume of normal saline by gavage,while the group RN,RNP and RNC were given corresponding drugs by gavage,for 4 weeks.After 4 weeks,the rats in each group were sacrificed for collecting serum and detecting the renal function(serum Scr,BUN),the renal tissues were taken for conducting HE and Masson staining.Then the renal tissue pathological damage severity was observed.The expressions of FN and LN in kidney tissue were detected by immunohistochemistry and the expressions of TGF-[β,α-SMA were detected by Western blot method.Results Compared with the NOR group,the model group exhibited the renal dysfunction(P＜0.01),renal interstitial severe fibrosis manifestation and increased collagen deposition(P＜0.05),and the expression of kidney tissues α-SMA(P＜0.01),TGF-β(P＜0.01),FN and LN were significantly increased.Compared with the model group,the renal function in various treatment groups was improved,Scr(P＜0.01)and BUN(P＜0.01)were significantly decreased,the renal interstitial fibrosis degree was reduced,collagen desposition was decreased(P＜0.05),renal tissue α-SMA(P＜ 0.05),TGF-β(P＜0.05),FN and LN expression were reduced to some extent,in which the effect of RNC group was stronger than that of the RN group and RNP group.Conclusion Notoginseng and guiding medicinals mediated notoginseng can retard the progression of renal interstitial fibrosis caused by adenine in CKD rat in varying degrees,its mechanism maybe reduce the expression of TGF-β protein.

Objective: To investigate the association between plasma selenium exposure and the risk of impaired glucose regulation (IGR). Methods: A case-control study was conducted to select IGR patients who were admitted to the outpatient clinic of the Department of Endocrinology to perform oral glucose tolerance test(OGTT) at the Tongji Hospital affiliated to the Tongji Medical College from September 2004 to 2016 as a case group. Participants with normal glucose tolerance recruited from an unselected group of population undergoing routine health examinations in the same hospital were selected as a control group. The control group was matched according to the age (±5 years old) and sex of the case group. The inclusion criteria for subjects recruited were as follows: age ≥30 years, body mass index (BMI) <40 kg/m², no history of a diagnosis of IGR or type 2 diabetes, and no history of receiving pharmacological treatment for hyperlipidemia or hypertension. Patients with any clinically systemic disease such as neurological or endocrine disease, acute illness, chronic inflammatory disease or infectious disease were excluded from the study. A total of 1 957 subjects, 897 in the case group and 1 060 in the control group, were included. Questionnaires were used to collect information of all subjects, and peripheral venous blood was collected after fasting and OGTT, respectively. Plasma selenium, fasting blood glucose, blood lipid (total cholesterol, triglycerides, high density lipoprotein cholesterol, and low density lipoprotein cholesterol) and 2 h OGTT plasma glucose concentration were detected, respectively. The subjects were divided into low, medium and high concentration groups according to the tertiles of plasma selenium concentration in the control group. The multivariate unconditional logistic regression analysis was performed to analyze the association between plasma selenium exposure and IGR. Results: The age (mean±SD) of the case and control group was (53.71±11.38) and (53.95±12.17) years old. The plasma selenium concentration [M (P₂₅, P₇₅)] in the case group was 92.81(77.07, 107.05) μg/L, which was significantly higher than the control group [88.73 (77.13, 100.88) μg/L] (P<0.05). The results of multivariate unconditional logistic regression analysis showed that after adjusting for age, sex, BMI, family history of diabetes and hypertension, the risk of IGR was higher in the high-concentration group and the low-concentration group compared with the middle-concentration group, the values of OR (95%CI) were 1.22 (95%CI: 0.94-1.59) and 1.81 (95%CI: 1.42-2.30), respectively. Conclusion The study suggested a U-shaped association between plasma selenium and IGR.

OBJECTIVE: To review targeted muscle reinnervation (TMR) surgery for the construction of intelligent prosthetic human-machine interface, thus providing a new clinical intervention paradigm for the functional reconstruction of residual limbs in amputees. METHODS: Extensively consulted relevant literature domestically and abroad and systematically expounded the surgical requirements of intelligent prosthetics, TMR operation plan, target population, prognosis, as well as the development and future of TMR. RESULTS: TMR facilitates intuitive control of intelligent prostheses in amputees by reconstructing the "brain-spinal cord-peripheral nerve-skeletal muscle" neurotransmission pathway and increasing the surface electromyographic signals required for pattern recognition. TMR surgery for different purposes is suitable for different target populations. CONCLUSION TMR surgery has been certified abroad as a transformative technology for improving prosthetic manipulation, and is expected to become a new clinical paradigm for 2 million amputees in China.
