The service object of gynaecology clinic operation is female,which involves reproductive organs,personal secrets,marriage,family and parenting.Not only the patients, but also their families,children and social relationship have close relationship with this operation.Tberefore,it is apt to cause contraditions between doctors and patients and difficult to solve.Medical staff should be strict with oneself,strengthen the study of medical ethics while learning to improve professional technique constantly.

Objective:To investigate the association between the apolipoprotein A5(APOA5) -1131T/C polymorphism and premature coronary heart disease in northern Chinese Han population. Methods: Using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and polyacrylamide gel electrophoresis (PAGE), we analyzed the genotype and allele distribution in 140 patients with premature coronary heart disease diagnosed by coronary angiography and 156 healthy controls. The levels of serum lipid profiles were also studied by biochemical methods. Results: The allele frequency of APOA5-1131T/C polymorphism in the premature coronary heart disease group was significantly higher (43.2% vs. 33.0%, P=0.011) than that in the control group. Compared with TT homozygotes, CC homozygotes exhibited a 2.809-fold (95% CI 1.331-5.927) increased risk of developing premature coronary heart disease. Logistic regression analysis found that this correlation was independent of sex, age, body mass index (BMI), smoking history as well as serum total cholesterol(TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) levels; In premature coronary heart disease group, the triglyceride(TG) level in CC homozygotes was significantly higher than those in TC heterozygotes or TT homozygotes. Conclusion: The APOA5-1131T/C polymorphism has influence on serum TG level, and the APOA5-1131C allele is associated with the development of premature coronary heart disease in northern Chinese Han population.

OBJECTIVE To investigate the incidence of nosocomial infection (NI) in our hospital,analyze the related factors,and provide theoretical basis for better prevention and control of NI. METHODS A total of 19 203 inpatients from Dec 2006 to Nov 2007 were retrospectively analyzed,of which 387 inpatients suffering from NI. RESULTS The rate of NI was 2.02%,the highest infected rate was in ICU (24.32%). The main infection site was respiratory tract (57.58%). The species were predominated by Gram-negatives (52.00%). CONCLUSIONS The incidence of NI is connected with factors such as age,underlying diseases,invasive operation and the misusage of antibiotics.

Objective:To explore the relationship between the severity of cardiovascular disease with the expression of apolipoprotein(a) [apo(a)] and apolipoprotein B(apoB) in peripheral blood and their location in peripheral blood cells.Methods: In this report,we selected 4 patients with angiography which indicated that three coronary arteries were narrowed and 5 control patients with normal angiography.Arterial blood was collected and analyzed for lipid parameters in plasma.The mRNA expression of apo(a) and apoB in peripheral white blood cells and platelets were determined by RT-PCR and their protein expression by western blot.Moreover,the expression and location of apo(a) and apoB in white blood cells were determined by confocal microscopy and computer 3D analysis.Results: In plasma,levels of high density lipo-protein-cholesterol(HDL-C) and apolipoprotein A-Ⅰ(apoA-Ⅰ) in cardiovascular disease(CVD) patients were significantly less than those in the control patients[(0.62?0.05) mmol/L,(0.78?0.08) mmol/L vs(0.81?0.15) mmol/L,(0.9?0.07) mmol/L,P0.05).Studies with confocal microscopy indicated that proteins of apo(a) and apoB were co-expressed by a few cells of leukocytes and the ratio of apoB/apo(a) in cardiovascular disease patients was significantly less than that in the control patients(optical density value 1.60?0.12 vs 4.40?0.35,P

Objective To investigate the protective effect of meglumine adenosine cyclosphosp (MAC) on the cerebral ischemia-reperfusion (I/R) injury in rabbits.Methods Twenty four healthy rabbits were randomly divided into control group (n =6),I/R group (n =6),MAC pretreated group (n =6),and MAC treated group (n =6).Cerebral ischemia-reperfusion injury model was made by separating and electrocoagulating vertebral arteries and clipping common carotid arteries in the latter 3 groups after anesthesia.The sham-operated group underwent vessel separation without clipping.L/R group was administered with nothing,while MAC pretreated group with MAC before ischemia,and MAC treated group with MAC just after ischemia.Blood was gathered from jugular vein before ischemia,and 30 min,1 h,and 2 h after reperfusion for testing IL-8,superoxide dismutase (SOD) and malondialdehyde (MDA).The brain tissue slice was observed by optical microscope.Results Compared to control group and before ischemia,the levels of IL-8 and SOD in serum were significantly increased and decreased,and the levels of MDA was significantly increased at 30 min after reperfusion in I/R group; the levels of IL-8 and MDA in serum were significantly increased,and the levels of SOD in serum was significantly decreased at 1 h and 2 h after reperfusion in I/R group.The levels of IL-8 in serum was less at 30 min and 1 h and 2 h after reperfusion in MAC pretreated group than in I/R group.At 1 h and 2 h after reperfusion,the levels of MDA in serum was less and the levels of SOD in serum was higher in MAC pretreated group than in I/R group.At 1 h and 2 h after reperfusion,the levels of IL-8 in serum were less and the levels of SOD in serum were higher in MAC treated group than in I/R group.The levels of MDA in serum were less at 2 h after reperfusion in MAC treated group than in I/R group.Compared to I/R group,pathological change was lighter in the MAC pretreated and MAC treated group.Conclusions MAC has a fine cerebral-protective effect and has no side effect.

AIM: To study the degree of astigmatism, axial distribution and axial symmetry pattern of binocular astigmatism in primary and secondary school students aged 7-18 years with myopia.METHODS:A total of 239 cases(478 eyes)of primary and secondary school students aged 7-18 years who underwent keratoplasty for myopia correction at the Fifth Affiliated Hospital of Zhengzhou University from 2020 to 2022 were randomly selected, and optometry was performed under ciliary muscle paralysis and was statistically analyzed.RESULTS:Astigmatism degree: 0.25 to 1.00 D accounted for 78.5%, 1.25 to 2.00 D accounted for 17.1%, and >2.00 D accounted for 4.4%. The axial distribution of astigmatism: 86.6% was astigmatism with the rule, 5.9% was astigmatism against the rule, and 7.5% was oblique astigmatism; both genders and different astigmatism degrees were dominated by astigmatism with the rule, and there were differences with the other two axes(both P<0.05). Axial symmetry pattern of astigmatism: the median axial difference in astigmatism between the direct symmetry model and the mirror symmetry model was 7° and 10°, respectively, with no statistical significance in both models(P=0.158), and there was no difference between the two in gender, degree of astigmatism, and axial distribution of astigmatism, but in the age group of 7-12 years old, the difference between the axial astigmatism of the direct symmetry model and the mirror symmetry model was statistically significant(P=0.027).CONCLUSION:The axial distribution of binocular astigmatism in myopic primary and middle school students is mostly astigmatism with the rule; the degree of astigmatism is more common from 0.25 to 1.0 D; however, there is no tendency for axial symmetry pattern of astigmatism.
