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 In a prospective randomized controlled pilot study, effects of postoperative pulmonary complications on a conservative treatment surgery (CTS) and fast track surgery (FTS) treatment regimen in non-small cell lung cancer (NSCLC) patients undergoing pulmonary lobectomy were compared.Methods Eighty patients who underwent radical pulmonary lobectomy surgical treatment for non-small cell lung cancer disease from January 2008 to May 2010 in our hospital were random assigned to either fast track surgery treatment (40 FTS group) or conservative treatment surgery regimen (40 CTS group). Study endpoints were pulmonary complications ( pneumonia, atelectasis, prolonged air leak ＞ 7 days); Further parameters assessed in the postoperative course of patients were the need for postoperative mechanical ventilation, temperature at the end of the operation, length of stay (LOS) on intensive care unit (ICU) and day of discharge. Results The rate of postoperative pulmonary complications was 34. 21% in CTS group and 8. 33% in FTS group ( P ＜0. 05). Median length of stay on ICU was comparable in both groups ( 1 day),but the day of discharge was significantly different in both groups [( 11. 1 ±3.6)d vs ( 16. 6 ±5.7)d, P ＜0. 01]. Conclusion Using this fast track clinical pathway, the rate of pulmonary complications could be significantly decreased as compared to a conservative treatment regimen. Our results supported the implementation of an optimized perioperative treatment in lung surgery for non-small cell lung cancer patients undergoing radical pulmonary in order to reduce pulmonary complications after major lung surgery.

Objective To investigate the clinical outcome of correction of unilateral delayed orbitozygomatic complex fractures with digital guide plates.Methods The study involved 14 cases of unilateral delayed orbitozygomatic complex fractures treated between September 2007 and March 2012.Craniofacial structures were measured by thin-section CT before operation,followed by data input to the image processing software.Before and after the processing of images,three dimensional skull models were produced using rapid prototyping technique and applied to have surgical simulation.Digital guild plates were produced for guiding the reduction of fractures and orbital walls were reconstructed as well.Results All cases were followed up for a period of 6-11 months,which showed basic restoration of facial structure and significant correction of diplopia and enophthalmos,with no infection or dislocation of implants buried in orbit floor.Mild ectropion of the lower eyelid occurred in one case and temporary decrease of frontal wrinkle in two cases,but all recovered in 3-6 months postoperatively.Conclusion Digital guide plate is easy in operation and reliable for treatment of unilateral delayed orbitozygomatic complex fractures.

Objective To evaluate the role of the beta3 subunit of the voltage-gated sodium channel (Scn3b) in neuropathic pain in mice.Methods The target gene Scn3b was embedded in the vector pBROAD-mcs and pBROAD3-mcs-Scn3b plasmid was then obtained.The primary mice were bred.The primary mice mated with C57/B6 mice and the transgenic mice were then generated.DNA,RT-PCR and Western blot experiments were performed to confirm the mice in which Scn3b was over-expressed.The mice with Scn3b over-expression multiplied rapidly to carry out the follow-up experiment.Ten transgenic mice (Scn3b group) and 10 control mice in the same litter (Con group) of both sexes,aged 2 months,weighing 25-30 g,were randomly chosen to establish the model of neuropathic pain.The mechanical pain threshold was measured before operation and on 3,5,7 and 14 days after operation.Results There was no significant difference in the mechanical pain threshold at each time point between the two groups (P ＞ 0.05).Conclusion Scn3b is not involved in the development and maintenance of neuropathic pain in mice.
