Objective To compare the sedative efficacy and untoward effect of dexmedetomidine and midazolam in drunken patients after general anesthesia.Methods Thirty-eight drunken patients having underwent mechanical ventilation after general anesthesia were enrolled.The patients were divided into dexmedetomidine group and midazolam group with 19 cases each according to random digital table method.The sedation onset time,dysphoria,percentage of with good sleep quality,duration of mechanical ventilation,ICU length of staying and untoward effect were compared.Results The sedation onset time and duration of mechanical ventilation in dexmedetomidine group were significantly shorter than those in midazolam group:(45.6 ±8.9) s vs.(112.5 ±20.3) s and (9.4 ±2.1) h vs.(18.6 ±5.1) h,the patients of dysphoria in dexmedetomidine group was significantly less than that in midazolam group:6 cases vs.14 cases,the patients of good sleep quality in dexmedetomidine group was significantly more than that in midazolam group:12 cases vs.4 cases,and there were statistical differences (P＜ 0.05).There was no statistical difference in ICU length of staying between 2 groups (P ＞ 0.05).The patients of bradyarrhythmia in dexmedetomidine group was significantly more than that in midazolam group:9 cases vs.2 cases,but the patients of respiratory depression in dexmedetomidine group was significantly less than that in midazolam group:4 cases vs.12 cases,and there were statistical differences (P ＜ 0.05).There were no statistical differences in delirium and hypopiesis between 2 groups (P ＞ 0.05).Conclusion Compared with midazolam,dexmedetomidine is highly recommended to be used for the sedation of drunken patients after general anesthesia,but the incidence of circulatory adverse reactions should be paid attention to.

AIM To investigate whether pretreatment with prostaglandin E 1 (PGE 1) might protect myocardium against peroxidative injury in early phase and in delayed phase. METHODS Rats were pretreated with PGE 1 (25 or 150 mg?kg -1 ). Isoproterenol (ISOP)(80 mg?kg -1 ) were injected peritoneally (ip) to induce acute myocardial infarction 20 minutes (early phase) or 24 hours (delayed phase) after pretreatment. Hearts were removed punctually 24 hours after ip ISOP and were assayed for content of malonaldehyde (MDA), activity of glutathione peroxidase (GSH Px) and superoxide dismutase (SOD). RESULTS ISOP caused myocardial injury with increased MDA content and SOD activity, and decreased GSH Px activity. Pretreatment with PGE 1, at each dose and in both phase, decreased the MDA content ( P

AIM: To investigate the plasma neurotensin(NT) concentration in patients with coronary heart disease: acute myocardial infarction(AMI),unstable angina(UA),stable angina pectoris(SAP), old myocardial infarction (OMI), and to study the relationship between the plasma NT level and the myocardial ischemia . METHODS: The plasma NT concentration of 30 patients with AMI,32 patients with UA,35 patients with SAP, 31 patients with OMI and 32 normal controls were determined by radioimmunoassay(RIA). RESULTS: The plasma NT level in patients with AMI(24 h),in patients with UA when angina attacked is significantly higher than that of healthy controls. The plasma NT level in patients with SAP, in patients with OMI is not significantly different from that of healthy controls. The NT level of patients with UA when angina attacked is significantly higher than that after 2 weeks treatment (P

Objective:To explore the status of HIV infection, time trends and related factors of MSM in Harbin from 2009 to 2018 and provide evidences for comprehensive prevention and control strategies of MSM HIV/AIDS.Methods:From April to July during 2009-2018, continuous cross-sectional studies were conducted on MSM recruited through snowball sampling. The unified questionnaire was used to collect demographic, behavioral, and serological information. The SPSS 23.0 software was used for statistical analysis, and the Joinpoint 4.8.0.1 software was applied to the annual percent change (APC) for time trends analysis using the Joinpoint regression model.Results:A total of 4 813 MSM were surveyed in Harbin from 2009 to 2018. The overall HIV antibody positive rate was 11.3 % ( 543/4 813). Joinpoint regression analysis showed that there was an increase in the HIV antibody positive rate from 2009 to 2015, while the segmentation point was in 2015 ( Z=4.2, P<0.05) but, there was a decrease from 2015 to 2018( Z=-1.3, P=0.3). The positive rate of syphilis antibody was 12.9% (621/4 813). There was a decrease in the positive rate of syphilis antibodies from 2009 to 2013 ( Z=-2.8 ,P<0.05). There was a decrease in the positive rate of syphilis antibodies from 2013 to 2018 ( Z=-0.7, P=0.5). Results from multiple logistic aggression analysis showed that the risk factors associated with the prevalence of HIV infection including network recruitment (a OR=1.307, 95% CI: 1.057-1.617), age 30 and above (a OR=1.905, 95% CI: 1.235-2.939) and syphilis antibody positive (a OR=4.728, 95% CI: 3.751-5.961). Protective factors appeared: knowledge of HIV/AIDS (a OR=0.598, 95% CI: 0.433-0.825) and consistent use of condom during anal sex in the past six months (a OR=0.683, 95% CI: 0.550-0.850). Conclusions:The HIV antibody positive rate peaked in 2015 among MSM in Harbin from 2009 to 2018, first increased and then decreased. The positive rate of syphilis antibody showed a decreasing trend. Intervention models based on social media software, age 30 and above and syphilis antibody-positive need to be explored. It also promotes condom use and referral for syphilis among MSM.

Objective: The purpose of this study is to investigate the anti-diabetic effects of linarin, a flavonoid extracted from Chrysanthemi Indici Flos (CIF), and its potential mechanisms. Methods: The effects of linarin on cell viability and glucose consumption in HepG2 cells were measured. Meanwhile, monosodium glutamate (MSG) mouse model was constructed to monitor the changes of insulin tolerance, glucose tolerance, triglyceride and cholesterol. The protein expression levels of p-AMPK, p-ACC, PEPCK and p-GS were detected by Western blot. Results: Linarin could increase the relative glucose consumption of HepG2 cells, improve insulin tolerance and glucose tolerance, and decrease the levels of triglyceride and cholesterol of MSG mice. Simultaneously, the expression levels of p-AMPK and p-ACC in HepG2 cells and the liver tissue of MSG mice were increased, while the expression levels of PEPCK and p-GS were decreased after treatment with linarin. Conclusion: Insulin resistance could be ameliorated by linarin in type 2 diabetes, and its mechanism may be related to AMPK signaling pathway.

Standardization is the universal language of the world, and standardization of traditional Chinese medicine (TCM) is essential for its communication in China and globally. However, the principles and methods of TCM acupuncture standardization have been unclear and inadequate in the early stages. Based on an investigative approach to understanding the current status, identifying problems, and finding solutions, our team has established basic principles of TCM acupuncture that embody Chinese wisdom, evaluated the international strategic environment systematically, proposed the principle of “importance of harmony and exercise of impartiality”, and established basic working principles. A series of methods for TCM acupuncture standard development and evaluation have been constructed, including general standards for the revision of TCM acupuncture standards, the first TCM acupuncture clinical research management specification, a shared full chain technology platform, a data center, and an evaluation research base for TCM acupuncture clinical research. Evaluation criteria for ancient literature and expert experience, a recommendation method for the “three main and three auxiliaries” TCM guideline for prevention were established, and quantifiable assessment methods of TCM standard applicability were proposed. These findings provide methodological guidance for TCM acupuncture standardization.
