ObjectiveTo evaluate the effect of Astragali Radix (AR)-Angelicae Sinensis Radix (ASR) drug pair on supplementing Qi and activating blood circulation in rats with Qi deficiency and blood stasis and provide a theoretical basis for clinical rational medication and identification and quality control of compound pharmacodynamic substances from the three aspects of characteristic map, identification of pharmacodynamic substances, and comparison of blood components. MethodHigh-performance liquid chromatography (HPLC) was employed to establish the fingerprint of AR∶ASR (3∶1), and ultra-high performance liquid chromatography-Q-Exactive Orbitrap-mass spectrometry (UPLC-Q-Exactive Orbitrap-MS) was employed to analyze the ingredients of the decoction. Adult male Wistar rats with SPF grades were selected and randomly divided into a blank group, a model group, a 3∶1 group, and a 5∶1 group. The rat model of Qi deficiency and blood stasis syndrome was prepared by controlling food intake and swimming in cold water every day. In parallel, each group was given medicine (or water) once a day. The dose of drug groups was 10.2 g∙kg-1, and the model group and blank group were given the same amount of distilled water for 15 d. Animal behavior, body weight, whole blood and plasma viscosity, thymus index, spleen index, the levels of adenosine triphosphate (ATP), adenosine diphosphate(ADP), von willebrand factor (vWF), and ATP/ADP value in serum of rats were recorded. The morphology of vascular endothelium was observed by hematoxylin-eosin (HE) staining and scanning electron microscopy. UPLC-Q-Exactive Orbitrap-MS was used to analyze prototype and metabolic components in serum. ResultThe fingerprint of AR-ASR drug pair (AR-ASR 3∶1) was established. UPLC-Q-Exactive Orbitrap MS identified 49 chemical components in vitro and preliminarily identified 11 prototype components absorbed into blood in vivo. As compared with the blank group, the body mass decreased significantly (P<0.01), the whole blood (high shear, middle shear, and low shear) viscosity and plasma viscosity were significantly increased (P<0.05, P<0.01), the thymus index and spleen index decreased significantly (P<0.05, P<0.01), serum ATP content decreased significantly (P<0.01), ADP content increased significantly (P<0.01), ATP/ADP value decreased significantly (P<0.01), and vWF content increased significantly (P<0.01). The results of HE staining and scanning electron microscopy showed that the vessels were partially damaged, showing the structural disorder of the intima, the bulge, defect, and roughness of the endothelium, and the obvious cell adhesion and migration in the model group. As compared with the model group, the body mass also increased significantly (P<0.01). The results of whole blood and plasma viscosity showed that the whole blood low shear viscosity was significantly decreased in the 3∶1 group (P<0.05). The results of thymus index and spleen index showed that 5∶1 group significantly increased the thymus index of rats (P<0.05). The results of serum ATP and ADP levels showed that the 5∶1 group had more significant effects on ATP and ADP levels (P<0.05), and both groups significantly reduced ATP/ADP values (P<0.01). The results of serum vWF level showed that the vWF content in the 3∶1 group decreased significantly (P<0.05). The results of HE staining and scanning electronic microscopy showed that the damage of vascular endothelium was improved in the treatment group and the structure of intima was neat. ConclusionAR-ASR drug pair can improve the macro and micro indexes of rats with qi deficiency and blood stasis in the 3∶1 and 5∶1 groups. Overall, the 5∶1 ratio has a better effect on supplementing Qi but 3∶1 ratio has a better effect on promoting blood circulation.

Objective:To explore the expression of vasohibin-1 (VASH1) and vascular endothelial growth factor A (VEGF-A) and clinical significance of VASH1 in gastric carcinoma.Methods:The expression of VASH1 and VEGF-A were detected by immunohistochemistry in formalin-fixed and paraffin-embedded sections in 56 pairs of gastric cancer and corresponding paraneoplastic tissue specimens. The correlation between the expression of VASH1, VEGF-A, clinicopathological parameters and prognosis were analyzed.Results:VASH1 and VEGF-A expression was significantly higher in gastric cancer tissues than normal paraneoplastic tissues. VASH1 and VEGF-A protein were expressed in 79% and 82% of gastric cancer tissues, respectively. A positive correlation was found between Vasohibin-1 and VEGF-A expression in gastric cancer tissues. VASH1 expression has significant positive correlation with TNM stage, tumor stromal invasion, tumor gross types and distant metastasis. Patients with high VASH1 expression had significantly worse overall survival (OS) and progression-free survival (PFS) than those with low VASH1 expression.Conclusion:VASH1 might be a clinically relevant predictor of patients in gastric cancer.

Objective:To investigate the expression of CD157 and its significance in colorectal cancer.Methods:The expression of CD157 was detected in 50 cases of colorectal cancer tissues and corresponding adjacent normal colorectal tissues by immunohistochemistry. The correlation between the expression of CD157 and clinicopathological parameters and prognosis was analyzed statistically.Results:Higher expression of CD157 protein was observed in colorectal cancer than that in normal colorectal tissues (72% vs. 20%, χ 2=25.09, P<0.01). Moreover, High expression of CD157 was correlated with the tumor size (χ 2=7.368, P=0.007), TNM stage (χ 2=9.223, P=0.002), the depth of tumor infiltration (χ 2=4.158, P=0.041), distant metastasis (χ 2=5.521, P=0.019), vascular invasion (χ 2=6.307, P=0.012) and microsatellite instability (χ 2=4.778, P=0.029), but not with gender, age, histology type, location, differentiation grade, lymph node metastasis, nerve infiltration or Kras mutation (all P>0.05 respectively). Patients with low expression of CD157 had longer survival (45±4 )months than those with high expression (30±3)months (χ 2=5.234, P=0.022). Conclusions:High expression of CD157 in colorectal cancer tissue is related to poor survival of postoperative patients.

<p><b>OBJECTIVE</b>To systematically review the safety of application of enhanced recovery after surgery(ERAS) to laparoscopic bariatric surgery.</p><p><b>METHODS</b>The randomized controlled trials (RCTs) or case-controlled trials concerning application of ERAS principles in bariatric surgery were collected by searching several national and international online databases, including PubMed, Cochrane Library, CNKI, EMBASE and Wanfang databases. Data collection was completed in October 2016. The ERAS protocol covered three phases (preoperative, intraoperative, and postoperative), including preoperative counseling, reduced fasting, early ambulation, early oral feeding, etc. The endpoints included at least one of the following parameters: length of stay (LOS), operation time, readmission rate within 30 days, morbidity of postoperative complication (major/minor), and reoperation rate within 30 days. The quality of enrolled literatures was evaluated according to Cochrane Handbook and Newcastle-Ottawa Scale. RevMan 5.2 software was applied to perform meta analysis. The weighted mean difference (WMD) was used to combine the statistics for the measurement data, and the ratio and its 95% confidence interval were used to combine the statistics for the counting data. Subgroup analysis was conducted based on the quality of the enrolled literatures for the results of high heterogeneity.</p><p><b>RESULTS</b>A total of 7 studies, including 1 randomized controlled trail and 6 case-control studies, with 3264 patients were enrolled. Among the 3264 patients, 2051 received ERAS management (ERAS group) and 1213 received traditional perioperative management (control group). Meta analysis showed that compared with control group, ERAS group had shorter operative time (WMD=-17.56, 95%CI: -29.50 to -5.62, P=0.00), shorter length of hospital stay (WMD=-1.11, 95%CI: -1.31 to -0.92,P=0.00). There were no statistically significant differences between the two groups in the morbidity of postoperative major complication(OR=1.21, 95%CI:0.87 to 1.69, P=0.26) or minor complication (OR=1.25, 95%CI:0.99 to 1.58, P=0.06), re-admission rate within 30 days (OR=1.07, 95%CI: 0.81 to 1.43, P=0.63) and re-operation rate within 30 days(OR=1.33, 95%CI: 0.84 to 2.11, P=0.23).</p><p><b>CONCLUSION</b>Application of ERAS protocols to bariatric surgery is safe and feasible, which can also reduce length of hospital stay and operative time, and accelerate recovery.</p>

Clinical practice guidelines play an important role in practitioner and patient decisions regarding appropriate clinical health care and in health policy formation. In the guideline development process, inappropriate methodologies and development strategies significantly influence the quality of guidelines; therefore, research and evaluation of guidelines have great significance. The original Appraisal of Guidelines for Research and Evaluation (AGREE) instrument was published in 2003 by a group of international guideline developers and researchers. AGREE has important significance for the quality guarantee and successful implementation of guidelines, and has extensively achieved endorsement since 2003. In 2009, The AGREE Collaboration has developed the AGREE II by refining the original AGREE instrument. At present, the AGREE II has already replaced the original AGREE instrument; however, related introduction regarding AGREE II has not been found in China. The authors of this article briefly introduce the AGREE II, and believe that it will add value to research and evaluation of the guidelines as a whole.
