Objective To study on the relationship between psychological harmony and mental health of health care providers. Methods Surveys on psychological harmony and mental health were conducted in 313 health care providers in Heibei Province by psychological harmony and SCL-90 questionnaire. Results The general psychological harmony,and mental health level of health care providers is lower than the national level; The psychological harmony and its dimensionality of health care providers is affected mainly by many factors such as emotional stability, the level of patients' cooperation, on-duty situation in holiday time, salary, the rate of solving difficult miscellaneous diseases, the number of medical tangle and paranoid symptoms.etc., among which solving difficult miscellaneous diseases effectively is the most important factor. Conclusion The general psychological harmony situation does not affect health care providers' mental health.

Aim To investigate the effect of oxymatrine on lipid metabolism regulated genes in liver in fat-in-duced insulin resistance in ApoE -/- mice.Methods Seventeen C57BL/6J male mice were selected in normal control group.Sixty-eight ApoE -/- mice with high fat diet for 1 6 weeks,were randomly divided into model group,oxymatrine low,middle and high dose groups.Then they were gavaged for 8 weeks.Body weight and general biochemical indicators were deter-mined in mice.The mRNA and protein expression lev-els of LPL,FAT/CD36,CPT1 ,UCP2,SREBP-1 c,FAS and ACC were examined by real-time PCR and West-ern blot in the liver.Results Compared with model group,oxymatrine reduced body weight(BW),fasting
blood glucose (FBG),cholesterol (TC ),triglyceride (TG),free fatty acids(FFA),fasting plasma insulin (FINS)and insulin resistance index(HOMA-IR)(P <0.05),while improved glucose infusion rate (GIR). Oxymatrine down-regulated the mRNA and protein ex-pression of LPL,FAT/CD36,UCP2,SREBP-1 c,FAS and ACC(P <0.05),and up-regulated the mRNA and protein expression of CPT1 in varying degrees (P <0.05).Conclusion Oxymatrine can regulate the ex-pression of lipid metabolism regulated genes in liver and improve insulin resistance in ApoE -/- mice in-duced by high fat diet.

Objective To clarify the intravenous thrombolysis utilization of acute ischemic stroke patients in Huashan hospital,and to analyze the factors affecting thrombolytic therapy compliance.Methods The data from a prospective cohort were analyzed.Consecutive acute stroke and transient ischemic attack patients from Huashan Hospital emergency room were recruited in 2014.Eligible ischemic stroke patients were divided into two groups according to intravenous thrombolysis or not.Results Totally 220 patients from emergency room were assessed in 2014.Among eligible patients,43 patients refused intravenous thrombolysis,whereas 59 patients chose this therapy.After multiple analysis,age,baseline NIHSS score,limb weakness,hemiplegic paralysis,facial paralysis or speech symptoms were significantly different between the two groups (U =936.000,P =0.024;U =284.500,P ＜ 0.01;x2 =8.824,P =0.003;x2 =7.732,P=0.005;x2 =5.169,P=0.038;x2 =5.040,P=0.025).Patients with NIHSS score ＜7 tended to refuse thrombolysis therapy in the receiver operating characteristic curve analysis (sensitivity 0.93,specificity 0.71).From 2008 to 2014,244 cases were analyzed in the thrombolysis database.Compared with patients with higher baseline NIHSS score,intracranial hemorrhage rate (2.6％ vs 19.4％;x2 =12.466,P ＜0.01),7-day mortality rate (1.3％ vs 16.9％;x2 =12.308,P ＜0.01) and 3-month mortality rate (3.8％ vs 21.1％;x2 =11.993,P ＜0.01) were lower in patients whose baseline NIHSS score ＜ 7 (minor group).A higher rate of excellent outcome (3-month modified Rankin Scale score ≤ 1)was observed in minor group (78.2％ vs 38.0％;x2 =34.403,P ＜ 0.01).Conclusions Intravenous thrombolysis was performed in 54.6％ of eligible ischemic stroke patients.Age,baseline NIHSS score,limb weakness,hemiplegic paralysis,facial paralysis or speech symptoms were associated with patients' decision of thrombolysis.The effectiveness and safety of intravenous thrombolysis were promising for patients with mild stroke.

AIM:To investigate the effects of ox-LDL on TLR2 and TLR4 expression and production of TNF-?,IL-10,IL-12,NO and MDA in macrophages and to observe intervention effect of GW1929 in above procedure.METHODS:The mouse peritoneal macrophages were pretreated with ox-LDL(50 mg/L,100 mg/L)and GW1929(20 ?mol/L)respectively for 24 h.The concentrations of MDA,NO-2/NO-3,TNF-?,IL-10 and IL-12 in the culture fluid were detected.Flow cytometry was used to observe TLR2 and TLR4 expressions after the mouse peritoneal macrophages were pretreated with ox-LDL(50 mg/L)and GW1929(20 ?mol/L)respectively for 6 h,12 h,and 24 h.RESULTS:The concentrations of MDA,NO-2/NO-3,TNF-? and IL-10 in ox-LDL(50 mg/L,100 mg/L)group were higher than those in control and GW1929 group obviously,but the concentrations of above index in ox-LDL(50 mg/L,100 mg/L)+GW1929 group were lower than those in ox-LDL(50 mg/L,100 mg/L)group apparently.No IL-12 in every group was detected.Expressions of TLR-2 in ox-LDL+GW1929(6 h,12 h,24 h)group were lower than those in ox-LDL(6 h,12 h,24 h)group respectively.TLR-4 expressions in ox-LDL+GW1929(12 h)were lower than those in ox-LDL(12 h)apparently.CONCLUSION:ox-LDL up-regulates TLR2 and TLR4 expressions and promotes the production of ROX,NO,TNF-? and IL-10 in macrophages.GW1929 is capable of inhibiting the above ox-LDL effects.

With the increasing of incidence rate of pediatric drug-resistant tuberculosis in recent years,pe-diatric tuberculosis as a threat to global childhood public health was serious disease and attracted more and more pediatrician concern. Pediatric tuberculosis often can′t result to typical clinical symptoms and imaging findings because its quantity of tubercle bacillus was little in lesions of infection,meanwhile,golden standard mycobacterium tuberculosis detection was time-consuming and low positive rate,pediatric tuberculosis can′t get timely diagnosis and therapy,mo-lecular diagnostic techniques of pediatric drug-resistant tuberculosis got widely clinical application and development for its advantage of rapid,accurate,efficiency and easy operation etc,several common molecular diagnostic techniques in pediatric drug-resistant tuberculosis were summarized,which would provide useful guidance for molecular diagnose of pediatric drug-resistant tuberculosis.

Objective:To observe the hypoglycemic and weight loss effects of liraglutide in type 2 diabetes mellitus (T2DM) com-plicated with obesity, and explore new treatment strategies for T2DM complicated with obesity. Methods: Totally 38 T2DM patients complicated with obesity with dissatisfactory blood sugar control treated with oral hypoglycemic drugs or insulin were enrolled and divid-ed into group A ( overweight group, 28 kg·m-2 >BMI≥24 kg·m-2 , 18 cases) and group B ( obesity group, BMI≥28 kg·m-2 , 20 cases) according to the body mass index ( BMI) . Liraglutide was used in all the participants for 12 weeks. The height, weight, BMI,HbA1c, fasting blood glucose(FBG),2-hour postprandial blood glucose(2hPG), fasting insulin(FINS),2-hour postprandial in-sulin (2hPINS),fast-c peptide(FCP), 2-hour postprandial c-peptide(2hCP) and insulin resistance index (HOMA-IR), pancreaticβcell function index( HOMA-β) of the two groups were detected before and after the liraglutide treatment. Results:After the treatment with liraglutide, HbA1c, FPG, 2hPG, FCP,2hCP,HOMA-β,HOMA-IR were significantly decreased (P<0. 01) than before in the two groups, while there were no significant differences between the groups(P>0. 05). However, the body weight in group B was sig-nificantly lower than before (P<0. 01), while there were no significant change in group A(P>0. 05). Conclusion: Liraglutide can effectively control blood glucose level, ameliorate insulin resistance and obviously decrease the body weight in the T2DM patients com-plicated with obesity.

Objective To evaluate the value of endorectal ultrasonography (ERUS) in assessment of mesorectal fascia (MRF) invasion in rectal cancer.Methods Data of 44 patients who accepted preoperative ERUS and total mesorectal excision surgery within a week were retrospective analyzed.There were 18 patients who accepted preoperative neoadjuvant chemotherapy and 26 patients didn't acceped.Taking the pathological diagnosis of circumferential resection margin (CRM) as the gold standard,the diagnostic efficiency of ERUS for the MRF invasion in rectal cancer was evaluated.Results The final pathological T staging was T1 in 2 cases,T2 in 17 cases and T3 in 25 cases.There were 2 cases of CRM positive results,and 42 cases of CRM negative results.With regard to the location of tumor,there were 16 cases located in low,and 28 cases in mid rectum.There were 26 cases located in anterior or antero-lateral wall of rectum,13 cases in posterior or postero-lateral wall,and 5 cases with a circle of rectum.The diagnostic accuracy were 83.33 ％ (15/18) and 92.31％ (24/26) for cases of accepting and not accepting the preoperative neoadjuvant chemotherapy;80.77％ (21/26) for cases located in anterior or antero-lateral wall,and 100％ (13/13) for cases located in posterior or postero-lateral wall;75.00％ (12/16)and 96.43 ％ (27/28) for low position and mid position tumors.The total diagnostic accuracy was 88.64％ (39/44).Conclusion ERUS can be an effective method in preoperative assessment of the MRF invasion in rectal cancer.

Aim To investigate the antidepressive-like effect of ethyl alcohol extract of Polyrhachis vicina Rog-er(EAPR),and its mechanism.Methods EAPR was prepared by ethanol extraction.Its anti-depressive effect was investigated by tail suspension test (TST) and forced swimming test (FST).Furthermore,repeated doses of reserpine was used for preparing the depres-sive rats.Results EAPR has definitely anti-depres-sive effect,as evidenced by the decreased immobility time in FST and TST at the doses of 8 and 4 g·kg -1 (P <0.05).In the repeated reserpine evoked depres-sive rats,EAPR antagonized the symptoms induced by monoamines depletion and attenuated the anhedonia, as manifested by reversed hypothermia,akinesia and sucrose consumption at the doses of 8 and 2 g·kg -1 (P <0.05,P <0.01).Neuro-chemical studies showed that AFPR significantly increased the concentration of monoamines,including 5-hydroxytryptamine (5-HT) and noradrenaline(NA)at the dose of 8 g·kg -1 (P <0.05),and had no effect on normal rats .Furthermore, EAPR increased the activity of superoxide dismutase (SOD)in serum,hippocampus and cerebral cortex at the dose of 8 g·kg -1 (P <0.05).Conclusion EA-PR possesses the definite antidep ressive properties, connected with the regulation of neurotransmitter me-tabolism and the nerve cells antioxidant effect.
