Objective Non-alcoholic fatty liver ( NAFL) is a metabolic disease and levocarnitine can be used to improve the energy metabolism of the patient .This study aimed to evaluate the clinical efficacy of levocarnitine in the treatment of NAFL . Methods We retrospectively analyzed 85 cases of NAFL treated by lifestyle intervention (control group, n=40) or by lifestyle intervention +levo-carnitine medication (medication group, n=45).In addition to lifestyle intervention, the patients in the medication group received oral levocarnitine at 10 mL tid for 4 weeks followed by a reduced dose of 10 mL bid for another 8 weeks. Results Twelve weeks after treat-ment, 37 cases (82.2%) in the medication group showed remarkable improvement and the other 8 failed to respond.In the control group, 23 cases (57.5%) were improved and 17 cases remained unimproved .There were statistically significant differences in the rate of therapeutic effectiveness between the two groups of patients (P<0.01).No adverse effects were observed during the levocarnitine medi-cation. Conclusion Lifestyle intervention +levocarnitine medication can improve NAFL .

Objective The control rate of blood pressure in hypertension patients is very low in our country , while follow-up intervention can significantly improve the situation .This study aimed to evaluate the clinical effects of anti-hypertension under follow-up intervention . Methods From October 2013 to October 2014 , 125 patients with hypertension were chose as the study objectives after first clinical anti-hypertension and were divided into intervention group (follow-up,n=65) and control group(no follow-up,n=60). Comparative analysis was made in blood pressure control , compliance with therapy and cardiovascular event incidence between the two groups after 12 weeks'intervention. Results After 12 weeks, diastolic and systolic blood pressure in intervention group was signifi-cantly lower than that in control group (P<0.05).Significant difference was also found in the compliance with drug-taking between in-tervention group and control group (73.8%vs 43.3%, P<0.01).During the follow-up period, 1 case in the control group suffered stroke and unstable angina pectoris hospitalized for treatment . Conclusion Follow-up intervention after clinical service can improve the efficacy of blood pressure control and encourage the patients to live healthy lifestyle .

Objective To improve the in vivo analgesic activity of acacetin and find leads for the development of new drugs, novel acacetin derivatives containing alkyl amide groups with different length of carbon chain were designed and synthesized according to the molecular structure of the active hit compound found in our previous work. Methods Using apigenin as the initial chemical ma-terial,the acacetin was synthesized through 3 steps,then the target compounds were prepared by conjugating hydroxy group of acace-tin at position 7 with bromoalkyl amides. The analgesic activity of the target compounds was evaluated by acetic acid writhing model of mice. Results and Conclusion Novel acacetin alkyl amide derivatives showed more potent analgesic activities than that of clinical medicine diclofenac,which could be used as leads for further development of new drugs.

OBJECTlVE To establish Tg(-6.3CYP3A65∶EGFP) transgenic zebrafish for quick, intuitive detection of heavy metals ( copper, cadmium and zinc) , dioxin-like PCBs ( PCB126) and other environmental pollutants. METHODS Tol2 transposon system was used to generate transgenic zebrafish lines Tg(-6.3CYP3A65∶EGFP) in which CYP3A65 promoter regualated labeled fluorescence. The effect of heavy mentals ( copper, cadmium and zinc ) and PCB126 on the relative amounts of CYP3A65 gene expression was determined by observing the change in fluorescence intensity. RESULTS The relative gene expression of CYP3A65 was significantly increased after 96 h exposure to copper 0.1 and 0.2μmol·L-1 , cadmium 0.35 and 0.7μmol·L-1 , zinc 1.5 and 3μmol·L-1 , and PCB126 2-32μmol·L-1 , respectively ( P<0.01) , but decreased after 96 h exposure to copper 0. 9 μmol·L-1 , cadmium 2. 7 and 5.4 μmol·L-1 , and zinc 24μmol·L-1 , respectively( P<0.01) . CYP3A65 gene expression was significantly increased after 168 h exposure to copper 0.1 and 0.2 μmol·L-1 , cadmium 0.35 and 0.7 μmol·L-1 , zinc 1.5 and 3 μmol·L-1, and PCB126 2-32 μmol·L-1, respectively(P<0.01), but decreased after 168 h exposure to copper 0.9 μmol·L-1, cadmium 2.7 and 5.4 μmol·L-1, and zinc 12 and 24 μmol·L-1( P<0.05) , in a concentration-dependent manner. CONCLUSlON The results suggest that zebrafish CYP3A65 gene expression and the CYP3A65 labeled fluorescence lines can be another candidate biomarker for detecting environmental pollutants.

Objective: To evaluate the effectiveness and to explore the releated factors of antiretroviral therapy among HIV/AIDS patients in Liangshan Yi Autonomous Prefecture, Sichuan Province. Methods: The method of convenience sampling was adopted in July 2017 to select the research objects who were accepted antiretroviral therapy (ART) over 6 months, older than 18 years and had HIV viral load in 2016, totally 400 cases. A retrospective study was used to collect the data, including social demography, medicine use, information of medical service acquisition, their own behaviors and cognition. 395 questionnaires were effectively recovered. χ² test and logistic regression were performed to examine relationships between factors and effects. Results: All of the 395 respondents were Yi-nationality. The average age of all cases was (39.23±7.52) years old and 223 were male (56.5%). Among 395 cases patients who were detect Viral load in 2016, 221 cases were under the number of 400 copies, thze effective rate of ART was 55.9%. Multivariate analysis showed that HIV/AIDS patients who missed the medication during the antiviral therapy had poor antiviral effects. Compared to those who adhered to medication, the treatment-ineffective OR (95%CI) of the patients missing the medication during the therapy was 7.06 (3.67-13.58); Compared to those who had adverse reactions that affect the therapy, the treatment-ineffective OR (95%CI) of the patients with mild adverse reactions that did not affect the therapy was 0.45 (0.23-0.87); Compared to the patients who used drugs during the treatment, the treatment-ineffective OR (95%CI) value of the antiretroviral therapy effect of non-drug users was 0.39 (0.16-0.91);Compared to the patients who have a correct cognition that insisting on taking medicine correctly can extend their life expectancy as a common person, the treatment-ineffective OR (95%CI) values for those who hold the view that could be prolonged by 10-20 years and not/unknown were 4.18 (1.59-10.99) and 6.64 (2.67-16.53). Conclusion The HIV/AIDS patients who receive ART were less effective in Liangshan, Prefecture. Missings drugs is one of the main influencing factors for the ineffective treatment.

Objective: To investigate the clinical value of combined detection of serum angiopoietin 2 (Ang-2) and Clara cell protein 16 (CC16) in the early diagnosis of acute respiratory distress syndrome (ARDS). Methods: Two hundred critical patients, treated at the Department of Critical Care Medicine, Bao'an District People's Hospital, Shenzhen during March 2015 and September 2016,were included in the study. According to the Berlin standard, patients were divided into two groups (n=100 each group): the ARDS group and non-ARDS group.The serum levels of Ang-2 and CC16 were measured by enzyme-linked immunosorbent assay (ELISA) on the first and second day of admission for each patient, in addition to completing APACHEⅡ score, medical history, vital signs collection and other biochemical indicators detection. Finally, paired-samples t test was used to analyze the data. The multiple ROC curve was used to calculate the area under the curve of the reference index of the serum levels of Ang-2 and CC16 on the first and second day. Results: On the first and second day, the serum levels of Ang-2 and CC16 were significantly higher in ARDS patients than those in non-ARDS patients, and there was a correlation between the serum levels of Ang-2 and CC16 in ARDS patients. The ROC curve showed that the combined detection of Ang-2 and CC16 on the first day achieved a highest sensitivity of 75.9% and detection of CC16 on the first day achieved a highest specificity of 70.2%. Conclusion Single-detection of serum levels of Ang-2 and CC16 could be used for early diagnosis of ARDS, and the combined detection of both has a higher sensitivity than single detection.
