Objective To explore the clinical effect of small incision extracapsular cataract extraction combined with implantation of artificial lens and phacoemulsification combined with implantation of artificial lens for patients with cataract.Methods One hundred and ten patients (142 eyes) with cataract were selected,55 patients (69 eyes) were treated with small incision extracapsular cataract extraction combined with implantation of artificial lens (observation group),and 55 patients (73 eyes) were treated with phacoemulsification combined with implantation of artificial lens (control group).After treatment,the corrected vision and quality of life were observed 1-week,1-and 3-month after operation,and the complications were recorded.Results The vision 0.6-1.0 of 1-week,1-and 3-month in observation group were 34 eyes (49.3％,34/69),61 eyes (88.4％,61/69) and 63 eyes (91.3％,63/69) respectively,in control group were 37 eyes (50.7％,37/73),64 eyes (87.7％,64/73) and 65 eyes (89.0％,65/73) respectively,there were no statistical differences (P ＞0.05).The quality of life score 1-week,1-and 3-month in observation group were (87.5 ± 10.7),(91.2 ± 5.3),(94.3 ± 5.8) scores respectively,in control group were (85.9 ± 11.5),(90.6 ± 6.7),(94.5 ± 6.0) scores respectively,there were nostatistical differences (P ＞ 0.05).The rate of complications in observation group was 23.2％ (16/69),in control group was 37.0％ (27/73),there was statistical difference (P ＜ 0.05).Conclusions The vision recovery and quality of life in cataract patients treated with small incision extracapsular cataract extraction combined with implantation of artificial lens are similar to treated with phacoemulsification combined with implantation of artificial lens.However,with fewer complications,small incision extracapsular cataract extraction combined with implantation of artificial lens is a more safe and reliable treatment method.

ObjiectiveTo investigate the clinical efficacy of Chinese medicineShuxin-Huoxue decoction on coronary heart disease and angina pectoris.MethodsThis study was a randomized controlled trial. 86 patients with coronary heart disease and angina pectoris and conformed to the indusive criteria were randomly divided into a control group and a treatment group, with 43 cases in each group. The control group was treated with conventional western medicine, the treatment group was treated with traditional Chinese medicineShuxin-Huoxue decoction. Serum homocysteine (Hcy) was measured by enzymatic cycling assay, high sensitive C reactive protein (hs-CRP) was measured by immunotubidimetric assay and left ventricular ejection fraction (LVEF), stroke volume (SV), cardiac output (CO), cardiac index (CI) were measured by color doppler echocardiography before and after treatment. The clinical effect of the two groups was evaluated.ResultsThe total effective rate of the treatment group and the control group was 90.7% (39/43) and 74.4% (32/43) respectively,there was significant difference (χ2=3.957,P=0.047). Followed up for 4 weeks, LVEF(65.7% ± 8.7% vs. 61.5% ± 8.4%,t=2.277), SV(86.9 ± 16.8 ml vs.79.2 ± 16.5 ml,t=2.144), CO(49.3 ± 9.1 ml/m2 vs. 44.7 ± 8.8 ml/m2,t=2.383), CI (3.7 ± 0.9 L/min?m2 vs. 3.3 ± 0.7 L/min?m2,t=2.301) of the treatment group were significantly improved after treatment than those of the control group (P<0.05), and the decrease of serum Hcy  (8.7± 3.7mmol/L vs. 11.4± 3.5mmol/L,t=3.476), hs-CRP (2.7± 1.1 mg/L vs. 3.5± 1.3 mg/L,t=3.081) level of the treatment group were better than those of the control group(P<0.01).ConclusionTraditional Chinese medicineShuxin-Huoxue decoction has good therapeutic effect on coronary heart disease and angina pectoris.

Objective Hyperglycemia was common during acute myocardiai infarction (AMI). This study investigated the impact of stress hyperglycemia on in-hospital outcomes in patients without diabetes hospitalized with AMI. Methods The study included 107 patients with AMI without diabetes, who were admitted to 81 hospital of PLA of Nanjing, China from January 2000 to May 2010. The in-hospital mortality and in-hospital complications were analyzed retrospectively. The exclusion criteria were: (1 ) patients < 18 years old; (2) patients with history of diabetes; (3) patients who initiated anti-hyperglycemic therapy during their hospital stay though without previously diagnosed diabetes; (4) patients with non-cardiovascular causes for AMI; (5) patients with hepatic failure, kidney failure, serious lung illnesses and end stage of malignant tumour; (6) patients administrated with steroid treatment recently and those with some diseases which had dramatic effect on glucose metabolism such as hyperthyroidism and cushing syndrome. Patients were categorized according to FBG levels into4 mutually exclusive groups; <7.0 mmol/L, ≥7.0 but <8.0 mmol/L, 8.0 to< 11. 1 mmol/L and ≥11.1 mmol/L. The Statistical Package for Stata, version 9.2 was used for statistical analysis. According to corresponding data analysis of /-test, ANOVA, rank test and exact propability were used respectively. Univariate logistics regression analysis was conducted followed by multivariate logistics regression analysis on significant variables. Results The incidence rate of stress hyperglycemia in patients with AMI without diabetes was 43. 9% (n =47). In non-diabetic patients, the mortality of the group of FBG≥7. 0 mmol/L was significantly higher than the group of FBG < 7. 0 mmol/L, which are 27.66% and 6.67%(P=0.0063)respectively,OR=5.35(95%CI 1.61 - 17.75,P = 0.0061). In-hospital complications for example lung infection, congestive heart failure, serious arrhythmias and acute cerebrovas-cular events were increased significantly in AMI patients with stress hyperglycemia. Multivariate logistic regression analysis for mortality were performed adjusting for risk factors which demonstrated FBG was a independent risk factors of in-hospital death , OR = 1.56(95%CIl.09 -2.23). Conclusions In-hospital mortality and in-hospital complications were significantly increased in patients with AMI without diabetes which developed stress hyperglycemia. Stress hyperglycemia was of great prognostic value for short-outcomes of AMI.

Objective: To investigate the protective effect of trimetazidine on experimental myocardial ischemia and its mechanism. Methods: Fifty mice received isoproterenol (20 mg?kg -1 ?2 d,ip) were divided into control and treatment groups. The myocyte ultrastructure,serum creatine phosphokinase (CK) activities and lactate dehydrogenase (LDH), myocardial malondialdehyde (MDA) and superoxide dismutase (SOD) were observed in 3 groups. Results: Compared with the controls,in 2 groups pretreated with trimetazidine (5 mg?kg -1 ?d -1 and 10 mg?kg -1 ?d -1 ? 7 d, ip), the degree of myocardial damage were significantly reduced;the serum CK and LDH were lower;the myocardial MDA was lower;the myocardial SOD was higher. Conclusion: Trimetazidine can significantly reduce the degree of myocardial damage produced by isoproterenol;and it may play an important role in protecting ischemic myocardium, the mechanism may be associated with reduced oxygen free radical production.

Objective To compare the effect of cisplatin or nedaplatin combined with paclitaxel as an adjuvant chemotherapy for cervical cancer.Methods Total 160 patients with cervical cancer in Ningqiang County Tianjin Hospital from February 2011 to December 2015 were divided into two groups according to different treatments.Cisplatin group was treated with TP chemotherapy,nedaplatin group was treated with TN chemotherapy,the curative effect,adverse reaction of chemotherapy,hospitalization time and treatment costs were compared between the two groups.Results The effective rate of cisplatin group was 79.26％ and nedaplatin group's was 82.05％,the two groups had no significant difference;The incidence of Ⅰ-Ⅳ grade hemoglobin,leukocyte of nedaplatin group were significantly higher than those in the cisplatin group (P ＜ 0.05),but between the two groups Ⅲ and Ⅳ grade had no significant difference,the incidence of Ⅰ-Ⅳ grade and Ⅲ-Ⅳ grade nausea,vomiting of nedaplatin group were significantly lower than cisplatin group (P ＜ 0.05);The hospitalization time of nedaplatin group was significantly shorter than cisplatin group (P ＜ 0.05),The cost of treatment between nedaplatin group and cisplatin group had no significant difference.Conclusion Cisplatin or nedaplatin combined with paclitaxel has similar efficacy in the neoadjuvant chemotherapy for cervical cancer,gastrointestinal adverse reactions of nedaplatin are lower than cisptatin,bone marrow suppression increase but still can be controlled,nedaplatin chemotherapy can shorten the duration of hospitalization,and hospitalization expenses were not significantly increased,which makes it more easily accepted by patients.

Objective To investigate the effect of hypertension and hyperuricemia (HUA) on renal function.Method Total 1 209 subjects undergoing health check up from December 2000 to December 2002 and 45 patients with renal disorders were enrolled in the study.The blood pressure,height,weight,renal function and liver function were measured; and the glomerular filtration rate (GFR) was calculated.The GFR in patients with hypertension,HUA and hypertension with HUA was compared.Results The incidence of hypertension in HUA group and non-HUA was 23.9％ (58/243) and 13.9％ (134/966),respectively (x2 =14.52,P =0.000).GFR in HUA with hypertension,HUA and hypertension groups were (69.1 ± 30.5),(82.8 ± 25.3) and (90.1 ± 21.7) ml · min-1 · (1.73 m2)-1,respectively (P ＜ 0.01).Logistic regression analysis showed that the risk factors for GFR were UA,systolic pressure and age.After 5 years of follow up,GFR in hypertension group was significantly decreased from (90.7 ± 18.1) to (85.6 ± 17.6)ml·min-1 · (1.73 m2)-1m,in HUA group from (86.3±10.9) to(62.1 ±8.2) and inHUAwith hypertension group from (77.9 ± 18.9) to (49.3 ±9.8) ml · min-1 · (1.73 m2)-1,UA and age were the long-term factors that affect GFR (P ＜ 0.05).Conclusions Both hyperuricemia and hypertension can impair the kidney function,if hypertension is complicated with hyperurecemia the effect is more marked.

BACKGROUND:Pathological mechanism of femoral head necrosis is not fuly known, and high-dose corticosteroids are prone to induce femoral head necrosis.
OBJECTIVE:To investigate the clinical effect of bone marrow mesenchymal stem cels combined with theaflavin on steroid-induced avascular necrosis of femoral head in rats.
METHODS: Rat bone marrow mesenchymal stem cels were isolated and culturedin vitro and compounded onto gelatin sponge, and then, divided into four groups: model group, decompression group, cel transplantation group and combined group. Models of steroid-induced avascular necrosis of femoral head were established using liquid nitrogen method. In the combined group, gelatin sponge carrying bone marrow mesenchymal stem cels was transplanted and 250 mg theaflavin was given daily after modeling.
RESULTS AND CONCLUSION:At 4 weeks after modeling, the femoral head samples in the four groups were round with exfoliation of articular cartilage that was pale in color. Then, the exfoliation of articular cartilage was aggravated in the model group, and some specimens appeared to colapse; the femoral head specimens in the combined group were round and pale. Until the 8th week after modeling, bone necrosis was increased in the model group; osteoblasts were found in the decompression group with fibrous calus formation; a few of empty bone lacunae appeared with irregular medulary cavity in the cel transplantation group; a large amount of new bone tissues formed in the combined group, and intramedulary adiocytes were in regular array. At 4 and 8 weeks after modeling, the number of empty bone lacunae was significantly lower in the combined group than the other groups (P < 0.05). These findings indicate that bone marrow mesenchymal stem cels combined with theaflavin is an ideal therapy for steroid-induced avascular necrosis of femoral head.

Objective To systematically compare propofol and isoflurane for myocardial protection in patients undergoing coronary artery bypass grafting (CABG).Methods Electronic databases were searched for randomized controlled clinical trials comparing propofol and isoflurane for myocardial protection in patients undergoing CABG.Data which were extracted independently by two reviewers included the general data of patients,premedication,induction of anesthesia and anesthetics applied during maintenance of anesthesia,level of cardiac troponin I (cTnI) before operation and at 6,12,24 and 48 h after operation,requirement for positive inotropic agents during operation,and development of myocardial infarction within 24 h after operation.Meta-analysis was conducted using Review Manager 5.0.2.Results Sixteen randomized controlled clinical trials involving 794 patients were included in this meta-analysis.The patients were divided into 2 groups:propofol group (n =405) and isoflurane group (n =389).There were no significant differences between the two groups in the plasma concentration of cTnI after operation,incidence of myocardial infarction within 24 h after operation,and requirement for positive inotropic agents during operation (P ＞ 0.05).Conclusion There is no significant difference between propofol and isoflurane for myocardial protection in the patients undergoing CABG.
