OBJECTIVE:To evaluate the improvement effects of sitagliptin on islet B-cell function in type 2 diabetic patients systematically,and to provide evidenced-based reference. METHODS:Retrieved from PubMed,Cochrane library,EMBase, CJFD,Wanfang database,VIP and CBM,RCTs about sitagliptin alone or combined with routine plan(trial group)vs. placbo alone or combined with routine plan(control group)in the treatment of type 2 diabetes were collected. Two reviewers independent-ly screened studies according to exclusion and inclusion criteria,extracted data,and assessed the methodological quality according to Cochrane Manual 5.1.0. Meta-analysis was performed by using RevMan 5.3 software. RESULTS:A total of 5 RCTs were includ-ed,involving 1253 patients. The result of Meta-analysis showed that changes of islet B cell function index(Homa-B)[sitagliptin alone group:MD=9.21,95%CI(4.16,14.25),P<0.001;drug combination group:MD=7.24,95%CI(0.80,13.68),P=0.03] and changes of insulin resistance index(Homa-IR)[sitagliptin alone group:MD=-0.40,95%CI(-0.44,-0.36),P<0.001;drug combination group:MD=-0.35,95%CI(-0.63,-0.07),P=0.02] of trial group were significantly better than those of control group,with statistical significance. CONCLUSIONS:Sitagliptin shows certain therapeutic efficacy in improving islet B cell func-tion and insulin resistance.

To observe the effect of "Yixintang" on the protection of the myocardium against ischemia reperfusion injury. Thirty Wistar rats, with their hearts isolated, were randomly divided into three groups: Yixintang group 1 (YXT1, with 0 01g "Yixintang" in each ml K H fluid), Yixintang group 2 (YXT2, with 0 1g "Yixintang" in each ml K H fluid) and control group. Left ventricular systolic output pressure (LVSP), rate of rise of left ventricular pressure (?dp/dt max ), left ventricular end diastolic pressure (LVEDP), heart rate, the content of malondialdehyde(MDA) in myocardial tissue were measured. The results showed that cardiac functions seemed to recover well after ischemia reperfusion injury in the group 2. The values of myocardial dynamics and hemodynamics indexes, including LVSP and ?dp/dt max , in the group 2 were obviously higher than those in the control group after ischemia reperfusion. The content of MDA in myocardial tissue was obviously lower in the group 2 than in the control group after ischemia and reperfusion. There was significant difference between Yixintang group 2 and control group ( P

Bronchiolitis obliterans(BO) is chronic airflow obstruction syndrome characterized by small airway obstruction and airflow limitation.In children, BO is secondary to severe infection of respiratory tract, and its development is related with inflammation and immune response.At present, the diagnosis of BO mainly is depended on the clinical manifestation, lung function and examination results of high resolution computed tomography (HRCT) because of difficulty of lung biopsy.Pulmonary HRCT is a non-invasive examination, and worthy of generalization.Currently, BO has no accepted effective treatment,early diagnosis and treatment can block the progression of BO.Due to lack of realization of BO, doctors and parents fail to give enough attention, BO has a prolonged course and very poor prognosis.

The widespread use of antibiotics has been effectively controlled serious life-threatening infections.The trituration,exploitation and use of antibiotics has been rapidly developed and applied to many fields.Due to the extensive use of various antibiotics,the emergences of drug-resistant bacteria and the rates of bacterial resistance have increased unceasingly which has been a common focus in the world.Resistant pathogen can reduce the effectiveness of antibiotics,and which is a serious threat to human health.De-escalation therapy of antibiotics can quickly and effectively control serious infections,and avoid bacterial resistance,and induce fungal infections.The rational use of antibiotics in pediatrics is very imperative,which includes strengthening management of antibiotics,and improving awareness and vigilance of the adverse reactions of antibiotics,and consummating specification of medication.Then,realize the correct,safe,rational medication of antibiotics.

The data can be downloaded, exported, and edited at the same the while fully access to treatment data by effective using of blood volume monitoring data management system (BVMS), in order to achieve data analyzed by using information management system. Conclusion:by understanding the correlation betweenΔBV and blood pressure screen composition can help to speculate the reasons for drop in blood pressure;by combining the examination data can help to control dry weight management, by fully accessing to data can help to manage hemodialysis patient data information management system, and according to patients expression and display of blood volume monitoring to determine the appropriate amount of ultrafiltration, adjust dry weight and develop an appropriate treatment plan.

Hedysari polysaccharide (HPS) is the main component of hedysarum polybotrys. HPS can inhibit tumor cell proliferation, block the cell cycle in the G2-M period, modulate apoptosis via the mitochon drial pathway, and improve the red blood cell innate immunity and T lymphocyte immune function. HPS can relieve low immunity caused by chemotherapeutics.HPS plays anti-tumor effects by these ways mentioned above.

Objective The non intrusive ultrasound combined with western medicine in the treatment of chronic prostatitis prostate/research and analysis of the effect of chronic pelvic pain syndrome.Methods96 cases of chronic prostatitis patients who were treated in our hospital from September 2016 to were randomly divided into the observation group, the control group 1 and the control group2.The observation group was treated with western medicine in the treatment of non intrusive prostate ultrasound;1 patients in the control group were given a single non intrusive prostate ultrasound treatment;control group 2 given a single treatment with Chinese and Western medicine.The clinical symptoms and NIH-CPSI scores were evaluated before and after treatment in each group.ResultsComparison between groups of patients before treatment NIH-CPSI score, no significant difference;after treatment, the NIH-CPSI score has decreased, there are obvious differences (P<0.05);the patients in the observation group were decreased significantly, the total score before treatment (26.21±2.20), the total score after treatment (11.77±1.90), there are obvious the difference (P<0.05).The treatment groups were compared with the efficiency, the total efficiency of observation group was 93.75%, the control group of 1 patients with the total effective rate was 75%, the control group of 2 patients with the total effective rate was 68.75%, there was significant difference in the treatment effect, with statistical significance (P<0.05).ConclusionNon intrusive ultrasound combined with western medicine in the treatment of prostate in compared with non intrusive ultrasound therapy and Western medicine alone in the treatment of prostate, has more significant treatment effect, should strengthen the clinical application and promotion.

Objective To observe the protective effect of Yixintang on injury of myocardial ischemia-reperfusion with isolated working heart. Method 40 mice are randomly divided into 5 groups:control group, Yixintang group 1, Yixintang group 2, Yixintang group 3 and Verapamil group. The change of left ventricular systolic output pressure (LVSP), rate of rise left ventricular pressure (?dp/dtmax), left ventricular end diastolic pressure (LVEDP), heart rate, as well as the contain of malondialdehyde (MDA) release and activity of superoxide dismutase (SOD) were measured as investigate indicator. Results After ischemia and reperfusion in Yixintang group, the heart can be good recovery its function. The values of myocardial dynamics and hemodynamics indexes LVSP and ?dp/dtmax, in Yixintang group 3 and Verapamil group the indicator were obviously higher than those in the control group, after ischemial and reperfusion. The content of MDA in myocardial tissue in Yixintang group 3 and Verapamil group after ischemia and reperfusion was obviously lower than in other groups. It also could depress the activity of SOD, there was significant difference among Yixintang group 3, Verapamil group and control groups (P

Objective To evaluate the diagnostic value, patients' tolerance and complications of double-balloon enteroscopy (DBE) in the diagnosis of small intestinal diseases. Methods During May 2003 to July 2005, a total of 68 patients (36 men, 32 women; mean age of 52. 6 years, range 15-78 years) with suspected small intestinal diseases were performed double-balloon enteroscopy (36 via mouth, 25 via anus and 7 via both mouth and anus according to suspected lesion location). Among them, obscure recurrent gastrointestinal bleeding was found in 39 cases, incomplete small intestinal obstruction in 7 cases, chronic abdominal pain in 14 cases, and chronic diarrhea in 8 cases. Results Approximately one half to three-fourth of the entire small intestine was observed by each approach in all cases except for 3 cases of severe intestinal stricture. The observation of the whole small intestine was finished by the combination of both oral and anal approaches in 7 cases. The appropriate use of X-ray made the enteroscopy easier and more helpful to determine the extent and location of the lesions. The lesions were found in 41 of the 68 patients, with a total positive rate of 60. 3%. The diagnostics yields was 26/39(62. 6%) in obscure recurrent gastrointestinal bleeding, 5 in incomplete intestinal obstruction, 6/14(43%) in chronic abdominal pain and 4 in chronic diarrhea, respectively. Fifty-seven cases (83. 8%) tolerated well without anesthesia while 11 cases received propofol anesthesia. No procedure-related severe adverse events or severe complications such as hemorrhage or perforation occurred in all cases. Conclusion Double-balloon enteroscopy is a well-tolerated and safe diagnostic approach with a high diagnostic yield in small intestinal diseases.
