BACKGROUND: Psychological disorders, such as depression and anxiety are relevant to pathogenesis and management of type 2 diabetes mellitus.OBJECTIVE: It was designed to investigate the influence of improving depression and anxiety in diabetes on metabolism of blood glucose.DESIGN: It was a randomized controlled comparative study.SETTING: It was conducted at the Cousulting Center for Clinical Psychology and the Endocrinology Department of Southwest Hospital Affiliated Third Military Medical University of Chinese PLA .PARTICIPANTS: Totally 43 inpatients with type 2 diabetes mellitus in the Endocrinology Department of Southwest Hospital Affiliated toThird Military Medical University of Chinese PLA were selected from October, 1999 to November 2000. All of them participated the investigation voluntarily, 24males and 19 females, with an age of 51±9 years old. They were randomly divided into 2 groups, 23 in experimental group and 20 in control group.METHODS: For experimental group, besides routine medications for diabetes, patients also Accepted anti-depression and anti-anxiety treatment, including paroxetine (20 mg, taking after breakfast everyday) and Alprazolam (0.4 mg, taking at noon, at evening and before sleep everyday). For control group, patients only Accepted routine medication for diabetes. Patients in the two groups were assessed before medication and after 4 weeks medication by Zung Self-Rating Depression Scale (SDS) and Zung Self-Rating Anxiety Scale (SAS). They were identified as depression and anxiety according to the Scales. Reduction rate of SDS/SAS score was used to assess the therapeutic effects: When the reduction rate was 50%-100%, the medication was significantly effective, when it was 25%-49% the treatment was effective, and when it was less than 25%, the treatment was noneffective.Reduction rate =(pre-treatment score-post-treatment score)/post-treatment score×100%. The fasting blood glucose level, 2-hour postprandial blood glucose level and the Glycosylated Hemoglobin (GHB, HbAl) were measured before treatment and after 4 weeks medication. Meanwhile, preprandial blood glucose level and 1-hour postprandial blood glucose level (6 times per day) were detected before treatment and at the 10th, 20th and 30th day during treatment. Reduction rate of blood glucose-(pre-treatment blood glucose level-post-treatment glucose level)/pre-treatment blood glucose level.MAIN OUTCOME MEASURES: These were main outcome measureglucose ①SDS/SAS scores, fasting blood glucose, 2-hour postprandial blood glucose and GHB before treatment and after 4 weeks treatment were measured in two group, ② and reduction rate of blood glucose.RESULTS: Six cases were omitted, 5 was in experimental group for financial pressure, intolerance to side effects of paroxetine and fears of the addiction of psychotropic drugs; the other one was in control group due to drop-out. There were 37 patients finished the investigation, 18 in experimental group and 19 in control group.①Comparison of SDS score/SAS core: After 4 weeks medication, it was observed that the post-treatment scores were significantly lower than pre-treatment scores in experimental group compared to control group[(41.05±7.05,41.88±10.57); (59.80±10.24,55.03±8.31 ), (t=2.41, 2.21, P ＜ 0.05)].②Comparison of fasting blood glucose, 2-hour postprandial blood glucose and reduction rate of blood glucose: After 4 weeks medication, the fasting blood glucose and 2-hour postprandial blood glucose in experimental group were significantly lower than those in control group(t=2.11,2.98, P ＜ 0.05-0.01)and the reduction rate of fasting blood glucose and 2-hour postprandial blood glucose in experimental group were significantly greater than those in control group (t=2.94,2.93,P ＜ 0.01). ③Comparison of GHB:After 4 weeks medication,the posttreatment GHB level in experimental group were significantly lower than pre-treatment GHB level[(8.2±2.0)%,(9.1±1.9)%, (t=2.14, P ＜ 0.05)].CONCLUSION: Anti-depression and anti-anxiety drugs not only can alleviate depression and anxiety symptoms significantly, but also can improve blood glucose metabolism. This may be attributed to an effect of anti-depression and anti-anxiety drugs in increasing the compliance of the patients to the medication for diabetes and decreasing the insulin resistance induced by negative moods.

Objective To explore the effect of linraglutide on expressions of plasminogen activator inhibitor 1 (PAI-1) and intercellular adhesion molecule 1 (ICAM-1) in cultured rat glomerular mesangial cells (RGMCs) stimulated by tumor necrosis factor α (TNF-α).Methods Cultured HBZY21 RGMCs were divided into 6 groups:normal control cells,TNF-α stimulated cells,liraglutide low (10 nmol/L),median (100 nmol/L) and high (1000 nmol/L) concentration incubated cells stimulated with TNF-α,PDTC intervention cells.The expressions of PAI-1 and ICAM-1 of each group were measured by ELISA and RT-PCR.Results The levels of PAI-1 and ICAM-1 protein and mRNA were remarkably increased by TNF-α (P＜0.05),and liraglutide could inhibit above up-regulated expressions (all P＜0.05).Compared with TNF-α-stimulated group,the expressions of PAI-1 and ICAM-1 were decreased by PDTC intervention (all P＜0.05).Conclusion Liraglutide can partly down-regulate the expressions of PAI-1 and ICAM-1 induced by TNF-α in RGMCs.

Objective To investigate the effect of intmopemtive intravenous penehyclidine hydrochloride on pulmonary function in patients undergoning thoracotomy.Methods Sixty ASA Ⅰ or Ⅱ patients aged 30-64 yr scheduled for elective radical esophagectomy for cancer were randomly divided into 2 group(n=30 each):penehyclidinc hydrochloride group and control group.Penehychdine hydrochloride 0.01 mg/kg(in nolmal saline 2 ml)was injected iv 20 min after opening the thoracic cavity in penehyclidine hydrochloride group.The equal vohlme of normal saline was injected iv in control group.Anesthesia was induced with fentanyl 2μg/kg,propofol 0.4μG/ml and rocuronium 0.6 mg/kg.The patients were tracheal intubated and mechanically ventilated.Anesthesia was maintained with remlfentanyl 0.1μg·min-1,propofol 2.0-2.5 μg/ml and intermittent iv injecfion of rocuronium.The use of remifentanyl and pmpofol was stopped 5 min before operation.Dynamic lung compliance (Cd) and peak airway pressure were monitored and recorded immediately before penehychdine hydrechlofide administration (T0) and at 3 min(T1),5 min(T2),10 min(T3),30 min(T4),1 h(T5),2 h (T6)after penehyclidine hydrochloride administration.Results There was no significant difference in Cd and peak airway pressure among different time points in control group(P>0.05).Cd was significantly higher,while peak airway pressure lower at T1-6 than at T0 in penehychdine hydrochlofide group(P<0.05).Cd wag significantly higher,while peak airway pressure lower at T1-6 in penehyclidine hydrochloride group than in control group(P<0.05) .Conclusion Intraoperative intravenous penehyclidine hydrochloride can improve the pneumodynamics and is helpful for ventilation in patients undergoing thoracotomy.

Objective:To put forward some suggestions by comparing the current situation in both private and public hospitals. Methods:Comparing the basic information, scale, human resource and medical service management situation between the private and public hospitals by analyzing the 2014 Beijing health authorities report. Results:There are 355 private hospitals, 76. 1% of them are not rated and 59. 7% are not appointed for the medical insur-ance, and 82. 8% need to rent the land. Although the number of private hospitals is more than that of the public ones, their actual beds and health resources respectively account for only 20. 2% and 16. 4%. Besides, their in-come, assets and services also account for only about 10%. Conclusions:There is a big gap between the private and public hospitals in terms of scale, human resources and service ability. The Government should implement the policy about the ratings, medical insurance and the use of land which is given to support the private hospitals, and speed up the diversified medical model.

Objective:To observe the clinical efficacy of Pingxiao capsules in the treatment of benign thyroid nodules. Methods:Totally 240 patients with benign thyroid nodules were randomly divided into the treatment group and the control group with 120 ones in each. The control group received levothyroxine at low dose, the treatment group received Pingxiao capsules, and the treatment course was 3 months. The type B ultrasonic inspection and lab inspection ( for thyroid hormones and blood lipid) were carried out, the cura-tive effect was compared and the adverse reactions were recorded as well. Results:Three patients in the treatment group and five ones in the control group were lost during the follow-up. After the treatment, the max diameter of thyroid nodule and the thyroid volume de-creased in both groups (P<0. 05), and those in the treatment group were smaller than those in the control group (P<0. 05). The levels of TSH and TC in the control group decreased after the treatment, which were significantly lower than those in the treatment group (P<0. 05). The total effective rate in the treatment group was higher than that in the control group, and the incidence of ad-verse reactions was lower than that in the control group, and both had significant differences between the groups (P<0. 05). Conclu-sion:Pingxiao capsules are effective and safe in the treatment of benign thyroid nodules.

Objective To investigate the genetic damage of dust storm fine particles on human blood lymphocytes. Methods The chromosomal aberration test and cytochalasin B blocked test were used to investigate the effect in vitro of dust storm fine particles (PM2.5) (0, 33, 100, 300 ?g/ml)collected in Baotou and Wuwei cities on human lymphocytes. Results In both dust storm and normal ambient air fine particles treated cells revealed an increase in the chromosomal aberration level and micronuclei frequency (MNF). The chromosomal aberration(CA)were characterized as chromatid break, chromosome break, acentric fragment, dicentric chromosome and gaps. With the increase of treatment concentrations the aberration level and MNF increased and the mitotic index(MI) and the nuclear division index (NDI) values declined in a dose-response manner(P0.05). The treatments of normal ambient air PM2.5 from Baotou City were significant higher than those of Wuwei City, but the treatments of dust storm PM2.5 were not significant different between the cities. Conclusion Dust storm PM2.5 from Baotou City and Wuwei City may cause human lymphocytes genetic damage and its genetic toxicity is related to the dose.
