Academic Journal of Second Military Medical University 1981;0(04):-
Objective:To investigate whether plasma lipoprotein-associated phospholipase A_(2)(Lp-PLA_(2)) activity correlates with severity and stability of coronary atherosclerosis and other established cardiovascular risk factors.Methods: Coronary angiography(CAG) was performed in 180 hospitalized patients who were suspected as having coronary heart disease(CHD).The severity of pathological changes of the coronary artery was assessed by the number of diseased coronary branches and Gensini′s score.According to the results of CAG,the 180 patients were divided into 2 groups: CHD group(n=112) and non-CHD group(n=68).The CHD patients were further divided into subgroups according to the clinical types,the number of diseased coronary branches and Gensini′s score.Lp-PLA_(2) activity,white blood cell(WBC) count,high sensitive C reactive protein(hsCRP),lipids,blood pressure and body mass index were measured.The age,sex and prior medical histories including hypertension,diabetes mellitus and smoking status were obtained before CAG in all patients.Lp-PLA_(2),WBC count and hsCRP were compared statistically between the subgroups,and correlation coefficients of Lp-PLA_(2) activity with WBC count,hsCRP and other conventional risk factors for CHD were calculated.Results: Plasma Lp-PLA_(2) activity in CHD patients was significantly higher than that in controls(P

Chinese medicinal formulae are the important means of clinical treatment in traditional Chinese medicine. It is urgent to use modern advanced scientific and technological means to reveal the complicated mechanism of Chinese medicinal formulae because they have the function characteristics of multiple components, multiple targets and integrated regulation. The systematic and comprehensive research model of proteomic is in line with the function characteristics of Chinese medicinal formulae, and proteomic has been widely used in the study of pharmacological mechanism of Chinese medicinal formulae. The recent applications of proteomic in pharmacological study of Chinese medicinal formulae in anti-cardiovascular and cerebrovascular diseases, anti-liver disease, antidiabetic, anticancer, anti-rheumatoid arthritis and other diseases were reviewed in this paper, and then the future development direction of proteomic in pharmacological study of Chinese medicinal formulae was put forward. This review is to provide the ideas and method for proteomic research on function mechanism of Chinese medicinal formulae.

Total glucosides of peony (TGP), containing the effective components of paeoniflorin (Pae), albiflorin (Alb) and so on, are effective parts of Radix Paeoniae Alba. And it possesses extensive pharmacological actions, one of which is hepatoprotective effect. In recent years, abundant of pharmacokinetics and pharmacodynamics research of TGP in hepatoprotective effects have been performed. However, the relative medicine of TGP in hepatoprotective effect has not been developed for clinical application. In order to provide reference for the development and rational clinical application of TGP, the research progresses of pharmacokinetics and pharmacodynamics of TGP in hepatoprotective effect were summarized in this paper. Pharmacokinetics research has clarified the process of absorption, distribution, metabolism and excretion of TGP in vivo, and liver injury disease can significantly influence its metabolic processes. Pharmacodynamics studies suggested that TGP can protect against acute liver injury, non-alcoholic fatty liver diseases (NAFLD), chronic liver fibrosis and liver cancer. However, the action mechanism and in vivo process about hepatoprotective effects of TGP have not been clearly revealed. How liver injury influences the metabolism of TGP and its integrated regulation through multiple targets need to be further studied. The combined pharmacokinetics and pharmacodynamics studies should be performed in favour of medicine development and clinical application of TGP in hepatoprotective effects.

OBJECTIVES:
To establish an automation system for detection of alcohol content in blood.
METHODS:
The determination was performed by automated workstation of extraction-headspace gas chromatography (HS-GC). The blood collection with negative pressure, sealing time of headspace bottle and sample needle were checked and optimized in the abstraction of automation system. The automatic sampling was compared with the manual sampling.
RESULTS:
The quantitative data obtained by the automated workstation of extraction-HS-GC for alcohol was stable. The relative differences of two parallel samples were less than 5%. The automated extraction was superior to the manual extraction. A good linear relationship was obtained at the alcohol concentration range of 0.1-3.0 mg/mL (r≥0.999) with good repeatability.
CONCLUSIONS
The method is simple and quick, with more standard experiment process and accurate experimental data. It eliminates the error from the experimenter and has good repeatability, which can be applied to the qualitative and quantitative detections of alcohol in blood.

OBJECTIVETo investigate the risk factors of intra-abdominal infection(IAI) after colorectal cancer surgery.
METHODSClinical and follow-up data of 773 colorectal cancer patients undergoing operation in our hospital from October 2011 to December 2014 were retrospectively analyzed. Patients were divided into intra-abdominal cavity infection group (110 cases, IAI group) and non intra-abdominal infection group(663 cases, non-IAI group). All the patients administered prophylactic antibiotics 30 minutes to 2 hours before operation. Univariate and multivariate analysis were performed to evaluate the risk factors of IAI.
RESULTSPreoperative factors associated with postoperative IAI included hepatic cirrhosis, kidney diseases, diabetes or other basic diseases, prophylactic use of drugs, hypoalbuminemia, anemia, intestinal obstruction, and American Society of Anesthesiologists (ASA) anesthetic grading score (all P<0.05). Postoperative factors associated with postoperative IAI included use of laparoscopy or stapler, united exenteration, existence of anastomotic fistula, time of drainage tube placement, operation time and tumor staging (all P<0.05). Multivariate logistic regression analysis showed that preoperative diabetes(OR=2.36, 95% CI:1.45 to 4.76, P<0.01), combined exenteration (OR=2.02, 95% CI:1.02 to 4.00, P<0.01), anastomotic leak (OR=4.41, 95% CI:1.77 to 10.99, P=0.001), operation time≥140 minutes (OR=2.88, 95% CI:1.78 to 4.67, P<0.01) and period of postoperative drainage≥10 days(OR=4.57, 95% CI:2.78 to 7.52, P<0.01) were independent risk factors of postoperative IAI, while the use of stapler was protective factor (OR=0.37, 95% CI: 0.23 to 0.60, P<0.01). Compared with prophylactic use of cephamycins plus metronidazole, cefuroxime plus metronidazole had a higher rate of IAI(OR=2.10, 95% CI:1.23 to 3.58, P=0.007).
CONCLUSIONSPrevention of postoperative IAI is required for colorectal cancer patients, particularly in those with preoperative diabetes, combined exenteration, anastomotic leak, operation time longer than 140 minutes and postoperative drainage period longer than 10 days. Preoperative use of cephamycins plus metronidazole has better efficacy in prevention of postoperative IAI.
