ObjectiveTo observe the intraoperative techniques of artificial nasolacrimal duct and evaluate the effectiveness.MethodForty-nine cases(56 eyes) ofchronic dacryocystitis underwent artificial nasolacrimal duct placement.The artificial nasolacrimal duct was dilated and the stent was retrogradely placed.Dacryocystography was performed before operation.ResultsArtificial nasolacrimal duct placement was technically successful in 53 eyes(94.64％),improvement rate was 3.57 ％ (2/56).The total effective rate was 98.21％(55/56) after operation.ConclusionInterventional artificial nasolacrimal duct placement is a safe,simple and effective method for the treatment of chronic dacryocystitis.

Objective The purpose of this study was to investigate the relationship between oxygen consumption (VO2) after recovery from incremental maximal exercise and the levels of the blood lactate (HLa), glucose and alanine metabolism. Method The VO2, HLa and plasma alanine were obtained using a modified version of Bruce' s protocol 30 min after exhaustion for 10 men. Result The VO2 after recovery has returned to the pre - exercise, but the HLa concentrations and plasma alanine were significantly increased from rest to maximal exercise, and were significantly decreased thereafter, but remained above resting values for 30 min after maximal stage. Conclusion we conclude that oxygen consumption after exhaustive maximal exercise is related to glucose resyntbesis through alanine metabolism, as compared with that from lactate metabolism.

Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) was a common complica-tion of small cell lung cancer (SCLC). Recent studies have suggested that the origin of this disease is related to seceration of tumor cells and application of medecine. The inappropriate antidiuretic hormone secretion can lead to disturbance of metabolism of water and sodium, resulting in hyponatremia. Because the symp-toms are atypical, the diagnosis is difficult. Many cases are misdiagnosed or misseddiagnosed. The primary tumor must be treated and the restriction of water intake is the main and effective method to deal with SIADH. Prognosis of SCLC patients with SIADH is poor in most reports.

The incidence of diabetes has a rapid increase trend trend in the whole world. In China, the incidence has come to 3%. The most of patients with type Ⅰ and part of type Ⅱ diabetes rely on exogenious insulin to control blood glucose;they not only have to bear the uncomfortbleness of insulin injection, but also inevitably to face the forward complications, so,the main concern in recent years is to rebuild the endogenous insulin secretion system. Many experiments show that pancreas transplantation not only can stop the development of insulin dependent diabe-tes, but also revert the already existing complications, just like with other organ transplants, the organ access and preservation is prerequisite for success. Because of the specificity of pancreas tissue, the effects of different organ preservation solution for the preservation of the pancreas varies. In this paper we will talk about the effect of UW preservation solution in the pancreas transplantation.

Objective To learn the burnout and turnover intention of physicians from township hospitals in Xi County,Henan province,for reference of health administrators and healthcare institution managers.Methods Cluster sampling method and qualitative interviews were used and all physicians from such hospitals were sampled for questionnaire survey in 2014,with 1 70 scales distributed.The questionnaire was the Markov Burnout Inventory generic version revised by Li Chaoping,and turnover intention questionnaire was that revised by Liang Kaiguang.Results 140 physicians from such hospitals were found with zero or low burnout (94.6%);Collaborative care in the county poses great positive effect on promoting professionalism and interpersonal relations, yet has limited positive impact on reducing workload and performance appraisal stress and increasing their income.Conclusion It is imperative to enhance training of managers of such hospitals for them to learn the appraisal method with organizational scale,and build a humanistic concern mechanism for physicians,for purposes of improving the organizational environment and minimize the burnout and turnover intention of the physicians.

Objective To explore the relationship between preoperative right ventricular ejection fraction(RVEF) and postoperative complications in the elderly patients with lung resection. Methods RVEF was assessed in 118 consecutive aged patients before pulmomary resection by echocardiography, 64 of whom received RVEF measurement again 3 weeks after operation. Results Preoperative RVEF in patients with postoperative complications was obviously lower than that in patients without ones. The frequency of postoperative complications in patients with different preoperative RVEF(

Objective To study the growth inhibision effect of disodium cantharidinate and Vitamin B6 injection on hepatocellular carcinoma cell line HepG2.Methods Different concentrations of disodium cantharidinate and Vitamin B6 injection were applied on the hepatocellular carcinoma cell line HepG2.The inhibition rate of HepG2 growth was measured by MTT assay.The apoptotic rate was detected with flow cytometry,and the morphology of apoptosis was observed by fluorescence microscope.Results The growth of HepG2 cells was significantly inhibited as well as the apoptosis of HepG2 cells was significantly encouraged by disodium cantharidinate and Vitamin B6 injection(P

Objective To explore the effects of low energy intravenous He-Ne laser irradiation of blood (ILIB) on cell proliferation, apoptosis and genotoxicity of lymphocytes in patients with cerebral infarction (CI). Methods The lymphocytes in peripheral blood in patients with CI were sampled before and after treatment and cultured, and then, some parameters such as the mitosis index (MI), cell cyclical kinetics index (CCKI), sister chromatid exchanges frequencies (SCEF) and apoptosis were analyzed in order to explore the effects of ILIB on lymphocytes. Results The proliferative activities of lymphocytes were significantly increased by ILIB (P0.05). After ILIB, the rate of apoptosis in patients with CI was significantly increased when compared with that before treatment and that of the control group, as revealed by flow cytometry (FCM) (P
