1.Clinical analysis of 531 cases of abdominal surgery with hypertension.
Chinese Journal of Practical Surgery 2001;21(5):280-282
Objective To evaluate adbomen surgery in patients who are found to have poorly controlled or untreated hypertension before operation.Methods From January 1997 to December 1998,the perioperative clinical data of 531 patients with hypertension and undergoing abdomen surgery in our hospital were retrospectively analyzed.Results The incidences of perioperative hypertensive events were not significantly different,between controlled and uncontrolled patients with grade one and grade two (P>0.05).In grade three and systolic hypertension,certain perioperative complications in patients with poorly controlled hypertension were higher than in those with well-controlled hypertension(P<0.05).Conclusion The patients with grade on e and grade two hypertension are not at increased operative risk.In Patients with grade three and systolic hypertension,perioperative complications are increased and elective surgery should be postponed until their blood pressure is brought under 180/110 mmHg over 1 to 2 weeks.

Chinese Journal of Ocular Fundus Diseases 2001;17(1):58-60
Objective To investigate the effect of subretinalfluid (SRF) with different grades of proliferative vitreoretinopathy (PVR) onbcl-2 oncoprotein expression in retinal pigment epithelium (RPE) cells and fib roblast (FB).Methods Using immunohistologicalstain ingtechnique and Westernblotting method to detect the expression of bcl-2 protein in RPE cells and FB under the stimulation of SRF.Res u ltsThe expression levels of bcl-2 increased in both types ofcells to a certain extent compared with those of the control group 4 hours afterthe cells subjected to SRF; 36 hours later, the expression levels of bcl-2 o f experimental groups decreased more quickly thanthose of the controlgroup, and the controlgroup showed relatively higher bcl-2 protein levels at the end of observation. Conclusions SRF may stimulate the e xpression of bcl-2 in RPE cells and FB under culture at early stage, but accel arate the declining of bcl-2 protein levels a certain time after subjected toSRF.
3.Correlative issues summary about time-to-event evaluation index in clinical observation.
China Journal of Chinese Materia Medica 2014;39(24):4877-4879
The time-to-event index is a kind of common evaluation index. It measures the speed of intervention effect. It is different from other index in research design, source material filling, data checking and statistical analysis. To obtain the time-to-event index, investigators can fill in the table directly and statistical analyst can compute after clinical observation. When filling in the source material or data checking, it is should be noticed that the logical relation between the time-to-event index and the visiting point and between the time-to-event index and the correlative other indicator. When statistical analyzing, it is an important issue how to deal with the cases whose time-to-event index does not appear till the observation period ends. Understanding the difference clearly can make the time-to-event index evaluate the effect of the intervention truly and make the clinical observation results reliable.

Objective To investigate the effect of subretinal fluid (SRF) with different grades of proliferative vitreoretinopathy (PVR) on bcl-2 oncoprotein expression in retinal pigment epithelium (RPE) cells and fibroblast (FB). Methods Using immunohistological staining technique and Western-blotting method to detect the expression of bcl-2 protein in RPE cells and FB under the stimulation of SRF. Results The expression levels of bcl-2 increased in both types of cells to a certain extent compared with those of the control group 4 hours after the cells subjected to SRF; 36 hours later, the expression levels of bcl-2 of experimental groups decreased more quickly than those of the control group,and the control group showed relatively higher bcl-2 protein levels at the end of observation. Conclusions SRF may stimulate the expression of bcl-2 in RPE cells and FB under culture at early stage, but accelarate the declining of bcl-2 protein levels a certain time after subjected to SRF.

Objective Ketamine has been shown to suppress pro-inflammatory cytokines like TNF-? and IL-6. The purpose of this study was to investigate the effects of ketamine on myocardial NF-?B expression and serum IL-6 level in a rat model of myocardial ischemia-reperfusion (I/R) .Methods Twenty-four healthy male SD rats aged 4-8 months weighing 200-250 g were randomly divided into four groups with 6 animals in each group : (A)control group; (B) I/R group; (C) ketamine 5 mg? kg-1 +I/R(I/R+K1) and (D) ketamine 10mg?kg-1 + I/R (I/R + K2) . The animals were anesthetized with intraperitoneal 10% chloral hydrate 40 mg?kg-1. Chest was opened and heart exposed. Left coronary artery was temporarily occluded at 1 mm inferior to left auricle for 30 min followed by 120 min reperfusion. Myocardial ischemia was confirmed by decoloration of apex and elevation of S-T segment. In control group (A) heart was exposed but left coronary artery was not occluded. In group C and D ketamine 5 mg?kg-1 or 10mg?kg-1 was given i.v. during ischemia. The animals were sacrificed at the end of 120 min reperfusion. A piece of myocardium (0.1 g) was obtained from apex for determination of myocardial NF-?B expression (Western-blot) . Blood samples were taken at 30 min and 120 min of reperfusion for determination of serum IL-6 level (ELISA) .Results The serum IL-6 level at 30 min and 120 min of reperfusion and myocardial NF-?B expression were significantly increased in I/R group (B) compared with those in control group ( P

Objective To analyze the monitoring results of influenza-like cases and their clinical features. Methods Three hundred and fifty cases of influenza-like illness were detected by rapid virological testing. At the same time, the clinical features were analyzed. According to the use of antibiotics, they were divided into two groups, antibiotics group(146 cases) and non antibiotics group(204 cases). Results The patients aged 20 to 29 was more than those in the other ages (P < 0.05) in 350 cases of influenza-like illness.There was significant difference in the morbidity of cough, sore throat, body aches, diarrhea and the blood leukocyte count, neutrophil percentage between two groups (P < 0.05). The body temperature recovery time was (2.5±1.5 ) d in antibiotics group and (2.4±1.9 ) d in non antibiotics group, and there was no significant difference between two groups (P > 0.05). Conclusions In the influenza surveillance program, a early warning system for influenza should established. Collecting and analyzing the information about the frequency,epidemiologieal characteristics and clinical manifestation of influenza-like cases, following up, making biological monitoring and using antibiotics reasonably is the clinically economic, convenient and practical means to prevention and control of influenza outbreaks.
