Objective To investigate the effect of ultrashortwave diathermy on pulmonary hypertension in patients with chronic cor pulmonale(CCP), and its mechanism. Methods Eighty-seven cases of acute phase CCP were divided into 2 groups: an ultrashortwave treatment group, in which 45 patients were treated with both ultrashortwave diathermy and conventional treatment; and a control group, in which 42 patients received regular treatment. The plasma levels of VEGF, ET-1 and the PaO_2, mPAP and FEV1.0 in the two groups were measured before and after treatment. Results In contrast to the control group, the FEV1.0 and PaO_2 of the experimental group were remar-kably increased, while their VEGF, ET-1 and mPAP were significantly decreased after treatment. VEGF and ET-1 were negatively related to PaO_2, and positively related to mPAP. Conclusions Ultrashortwave therapy is effective in treating pulmonary hypertension in patients with CCP. The mechanism for this may involve the synthesis and release of VEGF and ET-1.

Objective To evaluate comprehensively the effectiveness of transitional care for patients with diabetic in china. Methods Cochrane Handbook for systematic reviews of interventions was followed,and strictly designed search strategies,pub-lished literatures were searched through Chinese biomedical literature database(CBM),Wanfang,CNKI,VIP database.These data-bases were searched to collect the randomized controlled trials of transitional care for patients with diabetic in China.The retrieval time was limited from 2000 to 2014,All the literatures were selected according to the strictly designed strategies .A Meta analysis was performed by RevMan5.0 software.Results Totally 8 trials were included.Meta analysis showed that 6 months after the in-tervention,the continuing nursing and the control group in the incidence of complications of hypoglycemia had no significant differ-ence[RR= 0.69,95%CI (0.21,2.27 ),P = 0.540 ],while fasting glucose had significant difference [WMD = - 1.54,95%CI (-2.89,-0.1 9),P =0.030].12 months after the intervention,the continuing nursing and control groups in the incidence of com-plications of hypoglycemia [RR = 0.34,95%CI (0.1 6,0.72 ),P = 0.005 ],in fasting plasma glucose [WMD = - 1.03,95%CI (-2.78,0.72),P =0.250],in glycated hemoglobin [WMD =-1.73,95%CI (-2.43,-1.04),P <0.01]had significantly differ-ence.18 months after the intervention,the continuing nursing and control groups in the incidence of complications of hypoglycemia were significantly different[RR=0.28,95%CI (0.12,0.67 ),P = 0.004].Conclusion Transitional care intervention on patients with diabetes can reduce fasting blood glucose,glycated hemoglobin,and the incidence of complications,but the complications of in-tervention time should be greater than 6 months.

【Objective】 To confirm whether the preoperative fibrinogen to pre-albumin ratio (FPR) is a prognostic factor for patients with gastric adenocarcinoma and to analyze the relationship between FPR and clinicopathological characteristics of gastric adenocarcinoma patients. 【Methods】 We retrospectively reviewed the clinical data of 404 patients with gastric cancer who received radical gastrectomy in the Department of General Surgery, The First Affiliated Hospital of Xi’an Jiaotong University, from January 2012 to December 2016. We analyzed the preoperative FPR’s effects on the prognosis of patients with gastric cancer and the relationship between FPR and the clinicopathological variables. 【Results】 The optimal cut-off point of FPR obtained by ROC curve analysis was 15.0, and gastric cancer patients were divided into low FPR group (<15.0) and high FPR group (≥15.0). The univariate Cox regression analysis showed that age, preoperative anemia, tumor size, histological grade, TNM stage, and preoperative FPR were risk factors for the prognosis of gastric cancer (P<0.05). The multivariate Cox regression analysis showed that TNM stage and preoperative FPR were independent prognostic factors for gastric cancer (P<0.05). The subgroup analysis results indicated that the prognosis of patients in the low FPR group was better than that in the high FPR group of patients with stage Ⅰ-Ⅱ and stage Ⅲ gastric cancer (P<0.05). Further analysis showed that compared with those in the high FPR group, patients in the low FPR group had an older age, a larger proportion of males, a lower rate of anemia before surgery, smaller tumor diameter, and earlier TNM staging (P<0.05). 【Conclusion】 The preoperative FPR is an independent prognostic factor for gastric cancer. This study provides a clinical basis for its application in predicting the long-term prognosis of patients with gastric cancer.

【Objective】 To investigate the predictive value of visceral fat area （VFA） in patients with gastric cancer after radical gastrectomy. 【Methods】 A retrospective analysis was performed on 195 patients who underwent radical gastrectomy in the Department of General Surgery， The First Affiliated Hospital of Xi’an Jiaotong University from January 2014 to December 2017. CT image data and clinicopathological data within 1 week before surgery were collected. VFA was calculated by software， and the patients were divided into VFA-H group （n=96） and VFA-L group （n=99）. The relationship between VFA in different groups and long-term prognosis was compared. 【Results】 CT examination results showed that VFA value was （111±62） cm²， and BMI was positively correlated with VFA value （r=0.640， P<0.001）. ROC curve showed that VFA was more valuable in predicting the prognosis of gastric cancer （AUC=0.703， P<0.001） and better than BMI. Cox regression analysis of prognostic factors in gastric cancer patients： Univariate analysis showed that age， tumor length， TNM stage and VFA were the influencing factors for prognosis， while multivariate analysis showed that TNM stage III and VFA-L were independent risk factors for prognosis of gastric cancer patients. 【Conclusion】 VFA has a good predictive ability and can be used to evaluate the prognosis of gastric cancer patients after operation.

The clinical practice guidelines of traditional Chinese medicine （TCM） have problems such as limited clinical application and unclear implementation effects， which may be related to the lack of clinical practice evidence. To provide reliable and precise evidence for clinical practice， this article proposes a model of combining TCM guidelines with real-world study， which includes 4 steps. Firstly， during the implementation process of the guidelines， a high-quality research database is established. Secondly， the recommendations in the guidelines are evaluated based on the established database in multiple dimensions， including applicability， effectiveness， safety， and cost-effectiveness， and thus their effectiveness in practical applications can be determined. Thirdly， based on the established database， core prescriptions are identified， and the targeted populations and medication plans are determined. That is， the best treatment regimen is established based on the analysis of abundant clinical data regarding the effects of different medication frequencies， dosages， and duration on efficacy. Fourthly， the guidelines are updated according to the real-world evidence. The research based on this model can provide real-world evidence for ancient and empirical prescriptions， improving their application in clinical practice. Moreover， this model can reduce research costs and improve research efficiency. When applying this model， researchers need to pay attention to the quality of real-world evidence， ensuring that it can truly reflect the situation in clinical practice. In addition， importance should be attached to the clinical application of guideline recommendations， ensuring that doctors can conduct standardized diagnosis and treatment according to the guidelines. Finally， full-process participation of multidisciplinary experts is encouraged to ensure the comprehensiveness and scientificity of the study. In conclusion， the application of this model will contribute to the development of TCM guidelines responsive to the needs of clinical practice and achieve the goal of promoting the homogenization of TCM clinical diagnosis and treatment.
