Objective To evaluate the influence of fast-track surgery in perioperative period on the clinical outcomes of patients at nutritional risk in respectable esophageal cancer surgery perioperatively.Methods A total of 170 esophageal carcinoma patients receiving radical operation in our hospital from January 2008 to December 2013 were randomly divided into two groups by simple random method (n =85 each):one group was treated with the new concept of FTS-based on nutritional risk screening (FTS group),and the other control group received conventional perioperative management (CPM group).The postoperative first passage of flatus and defecation,time to drainage tube removal,postoperative hospital stay,and morbidity of the postoperative complication were recorded and compared.Results The time to drainage tube removal and length of postoperative hospital stay were significantly lower in the FTS group than those in the CPM group,and the overall postoperative complication rate was 7.06％ (6/85) in the FTS group and 20.00％ (17/85) in the CPM group (all P ＜0.05).In FTS group,the first flatus time was (59.01 ±2.73) h,the first defecation time was (3.35 ± 1.37) d,removing time of chest tube was (2.76 ±0.34) d,and postoperative hospital days was (8.16 ± 0.80) d; in the control group,they were (90.16 ±2.82) h,(4.78 ± 1.74) d,(4.39 ±0.25) d,and (10.93 ± 1.39) d respectively,showing significant differences (all P ＜0.05).The operative time was similar between these two groups.Conclusion The new concept of FTS by nutrition risk screening and intervention apparently can accelerate recovery after esophagngastrectomy,reduce the rate of overall complications,promote bowel function recovery,and decrease morbidity in the perioperative period for patients with esophageal carcinoma.

Objective To systematically evaluate the safety of high dose atorvastatin (80 mg daily) in Chinese patients. Methods Randomized controlled trials (RCTs) investigating 80 mg/ d atorvastatin vs. low-dose atorvastatin or placebo or blank were electionically retrieved in date bases of EMbase, PubMed, the Cochrane Library, WanFang, CNKI and WeiPu. Meta-analysis was performed using RevMan 5. 2 and Stata 11. 0 software. Results A total of 20 RCTs involving 2282 cases were included. The results of meta-analysis showed no significant differences betweent the 80 mg/ d atorvastatin group and the control group in the incidence of gastrointestinal adverse events (RR 1. 53, 95% CI 0. 85-2. 76, P = 0. 16), hepatic adverse events (RR 1. 53, 95% CI 0. 99 - 2. 36, P = 0. 05), muscular adverse events (RR 1. 51, 95% CI 0. 92 -2. 49, P = 0. 10), serious hepatic injuries ( RR 2. 33,95% CI 0. 88 - 6. 20, P = 0. 09) and serious muscular myopathies (RR 1. 40, 95% CI 0. 46 - 4. 30, P = 0. 56). Subgroup analysis by type of cotrast media used and durations of taking 80 mg/ d atorvastatin showed there were higher risks of gastrointestinal adverse events in the 80 mg/ d group when compared to blank control ( RR 4. 22, 95% CI 1. 11 - 16. 04, P = 0. 03). Conclusions The current evidence shows that 80 mg / d atorvastatin may be relatively safe in terms of adverse events in gastrointestinal tract, liver and muscular system, and relatively has risk in causing severe liver injuries and myopathies. With limited quantity and quality from the RCTs available, more high quality RCTs are needed to verify the above conclusion.

In traditional oral practice, the presystemic interactions with gut microbiota is an important mechanism underlying the holistic health benefits of Chinese herbal medicines (CHMs), making the study of CHMs distinct from the research of Western medicines of which the systemic exposure (level in blood) is the starting point and the core. Gut microbial metabolism complements host metabolism in maintaining metabolic homeostasis of many biologically important endogenous molecules and the disposition of numerous exogenous compounds. Among them, the widely distributed gut bacterial β-glucuronidases (BGUSs) coordinate with host UDP-glucuronosyltransferases (UGTs) to play a role in the occurrence and intervention of diseases by affecting the glucuronidation homeostasis and altering the intestinal local and/or systemic exposure of endogenous compounds and xenobiotics. On one hand, many ingredients of CHMs undergo enterohepatic circulation; On the other hand, CHMs can act on BGUSs directly or indirectly change the distribution and function of BGUSs through reprogramming gut microbiome. The multiple interactions between BGUSs and CHMs may play an important role in the overall therapeutic benefits of CHMs. This work firstly summarizes the latest research progress on BGUSs; then the physiological, pathological and pharmacological significance of BGUSs are exemplified with representative endogenous and exogenous compounds from the aspects of nutrient utilization, metabolic homeostasis, and therapeutic response based on the varied substrate spectra of BGUSs; finally, the scattered data in literature were integrated to summarize the multiple interactions between BGUSs and CHMs, highlighting the important role of BGUSs in the holistic actions of CHMs.

This study is to investigate the effect of artesunate on transforming growth factor-beta1 (TGF-beta1) induced epithelial-mesenchymal transition (EMT) and its possible mechanism. After the in vitro cultured RLE-6TN cells were treated with TGF-beta1 then artesunate intervened on it, after 24 h, expression of the markers of mesenchymal cell was assayed using Western blotting and real-time PCR analysis. Western blotting was also used to detect the effect of TGF-beta1 on the Smad3 and Smad7 expressions of RLE-6TN cells. Morphological alterations were examined by phase-contrast microscope, and ultrastructure changes by electron microscope. Incubation of RLE-6TN cells with TGF-beta1 resulted in the up-regulation of the expression of the mesenchymal cell markers, after artesunate intervened on it, resulted in the down-regulation of the expression. Meanwhile, incubation with artesunate intervened on RLE-6TN cells could lead to the apparent down-regulation of the expression of Smad3 and up-regulation of Samd7 and the transition of RLE-6TN cells to mesenchymal-like by TGF-beta1 induction, after artesunate intervened on it, RLE-6TN cells to epithelial-like. TGF-beta1 induced epithelial-mesenchymal transition process; artesunate can inhibit TGF-beta1-induced epithelial-mesenchymal transition process, the possible mechanism is up-regulation of the expression of Smad7 and down-regulation of the expression of Smad3, meanwhile inhibits phosphorylation of Smad3.

Objective To evaluate the cardioprotection induced by ischemic preconditioning ( IPC) and hypoxic preconditioning ( HPC) which were carried out by using the double cardiopulmonary bypass ( CPB) circuits in in vivo hearts of dogs. Methods Eighteen healthy male dogs, weighing 17?5-24?5 kg, aged 13-24 months, were divided into 3 groups ( n=6 each) using a random number table: my?ocardial ischemia?reperfusion group (group I∕R), IPC group and HPC group. The double CPB circuits were established as follows: systemic and coronary circulation, and independent systemic and coronary cir?culation was carried out. In group IPC, the aorta was clamped, and the coronary circulation pump was sus?pended for 5 min followed by 5 min opening, repeating for 3 cycles. In group HPC, the aorta was clamped, the coronary circulation was started, and pure nitrogen was insufflated for 5 min followed by 5 min of oxygen insufflation, repeating for 3 cycles. CPB was performed for 1 h starting from the time point immediately after IPC or HPC. Before splitting of sternum ( T1 ) , after establishment of double CPB circuits ( T2 ) , at the end of preconditioning ( T3 ) , and at 60 and 120 min after restoration of spontaneous heart
beat ( T4,5 ) , heat rate, mean arterial pressure, central venous pressure, left ventricular end?systolic pres?sure, left ventricular end?diastolic pressure and the maximum rate of increase∕decrease of left ventricular pressure were recorded. Blood samples were collected from the right internal jugular vein at T1 and T4,5 for determination of serum cardiac troponin I concentrations. The animals were sacrificed after determination of the parameter or after blood sampling at T5 , myocardial specimens were obtained for examination of the ul?trastructure and for detection of apoptosis in cardiomyocytes, and apoptosis index was calculated. Before aortic clamping, immediately after aortic unclamping and at 30 min after aortic unclamping, myocardial specimens were obtained for determination of ATP contents in cardiomyocytes. Results Compared with I∕R group, left ventricular end?systolic pressure was significantly increased, and the serum cardiac troponin I concentrations were significantly decreased at T4,5 , the myocardial ATP contents were significantly in?creased immediately after aortic unclamping and at 30 min after aortic unclamping, apoptosis index was sig?nificantly decreased ( P<0?05 or 0?01) , and the pathological changes were significantly attenuated in IPC and HPC groups. Compared with group IPC, the myocardial ATP contents were significantly increased (P<0?05), and the pathological changes were attenuated in group HPC. Conclusion Both HPC and IPC can exert cardioprotection when carried out by using the double CPB circuits, and HPC provides better cardioprotection than IPC in in vivo hearts of dogs.

Objective To explore the effect of scoliosis-specific exercises ( SSE) on patients with mild ado-lescent idiopathic scoliosis ( AIS) . Methods Thirty patients with mild AIS were assigned to a control group ( n=10) or an SSE group ( n=20) . The control group received routine health education, while the SSE group completed a 60-minute set of SSE 2 to 3 times a week for 12 weeks. The angle of trunk rotation ( ATR) , maximum Cobb angle and angle of vertebral rotation (AVR) were recorded. Bone strength parameters including the speed of sound (SOS), Z-score and percentile distal radius were measured. Surface electromyography ( sEMG) was performed for the erector spinae muscle. In addition, forced vital capacity ( FVC) and forced expiratory volume in one second ( FEV1) were measured and compared with the predicted values ( FVC/pred% and FEV1pred%) . A falling index ( FI) and quality of life ( QOL) were measured. Results Compared with before the treatment, the average maximum Cobb angle in the control group increased significantly after the lessons, but there was no significant difference in any of the other measures, including QOL. For the control group the activation rate of the concave side of the apex level erector spi-nae was significantly lower than on the convex side both before and after the lessons. The SSE group showed no sig-nificant improvement in their average ATR, maximum Cobb angle, AVR or FI results, but their average SOS, Z-score and percentile of the distal radius, FVC, FEV1 and motor function improved significantly after the treat-ment. Before the treatment the activation rate of their concave side was also lower than on the convex side, but after the treatment there was no significant difference between them on average. Conclusion Early SSE can prevent further deformation, promote bone strength, improve lung function reduce the difference in the motor control of the bilateral erector spinae muscles among patients with mild AIS. It can promote a better quality of life and is worth ap-plying in clinical practice.
