Objective To evaluate the perioperative period safety of improved transurethral plasma kinetic enucleation of prostate (TUPKEP) in high-risk benign prostatic hyperplasia (BPH) patients with coronary heart disease (CHD).Methods One hundred and twenty-eight BPH patients were selected,24 patients had CHD (with CHD group),among whom 10 patients were given transurethral vapor-resection of prostate (TUVP),and 14 patients were given improved TUPKEP; 104 patients didn't have CHD,among whom 22 patients were given TUVP,and 82 patients were given improved TUPKEP.The serum endothelin (ET)-1 was measured by specific radioimmunoassay at preoperative 2 h and postoperative 1,2,6 d,and complication was observed.Results All the patients were cured by operation,and left hospital smoothly.There were no statistical differences in the preoperative 2 h serum ET-1 in with CHD group and without CHD group (including all TUVP patients and improved TUPKEP patients) (P ＞ 0.05).The postoperative 1 and 2 d serum ET-1 levels of TUVP patients were significantly higher than those of improved TUPKEP patients,in with CHD group:(114.09 ± 15.33) ng/L vs.(94.77 ± 12.14) ng/L and (99.67 ± 9.87) ng/L vs.(88.21 ± 9.55) ng/L; in without CHD group:(70.21 ± 12.44) ng/L vs.(53.67 ± 9.02) ng/L and (61.18 ± 9.52) ng/L vs.(48.54 ± 9.15) ng/L,and there were statistical differences (P ＜ 0.05).There were no statistical differences in postoperative 6 d serum ET-1 in TUVP patients and improved TURKEP patients (P ＞ 0.05).In with CHD group,5 patients had ischemic ST-T change in the early postoperative period,and 3 patients had angina pectoris.They all were promptly treated,and the events were controlled.Serious complications did not present such as acute myocardial infarction (AMI),acute heart failure and sudden cardiac death,etc.Conclusions The postoperative BPH patients have vascular endothelial injury catholically,especially the high-risk patients with CHD.Furthermore,it might be one of the causes of the postoperative adverse cardiovascular events.Compared with TUVP,improved TUPKEP has a minor impact on vascular endothelial function,and it can reduce the postoperative adverse cardiovascular events in the BPH patients with CHD.Improved TUPKEP is a relatively safer surgical method for high-risk BPH with CHD.

Objective To study the clinical significance of chromosome karyotyping in pregnant women with a history of abnormal pregnancy. Methods The fetal chromosome karyotypes of 1 193 pregnant women with a history of abnormal pregnancy in Peking University First Hospital from January 4, 2005 to December 31, 2013 were analyzed. According to the etiology of their previous abnormal pregnancy, these women were divided into four groups: 273 women had children with inherited metabolic disorders or single-gene genetic diseases (group A), 81 women had children or fetuses with chromosome abnormalities (group B), eight cases had an abnormal chromosomal karyotype in either husband or wife (group C), and 833 women had abnormal pregnancy of unknown causes(group D). Results Forty-eight [4.0%(48/1 193)] and fetuses were found to have abnormal chromosomal karyotypes, including 26 cases of chromosome polymorphism variations and 22 cases of numerical and structural abnormalities (four cases of trisomy 21, four cases of numerical sex chromosome abnormalities, three cases of trisomy 18, three cases of extra small chromosome mosaicism, three cases of reciprocal translocation, one case of Robertsonian translocation, one case of chromosome six inversion between the arms, one case of chromosome three inversion between the arms, one case of mosaicism of trisomy 14 and one case of structural abnormality of chromosome 14). In group A, four cases (1.5%) of chromosomal abnormalities of clinical significance and four cases of chromosome polymorphism variations were detected. Meanwhile, 61 fetuses with inherited metabolic disorders or single-gene genetic diseases and two cases of gene mutation carriers were detected in group A, but among whom, there were no abnormal chromosome karyotype cases. In group B, two cases (2.5%) of chromosomal abnormalities were found. In group C, two cases (2/8) of reciprocal translocation were found, whose karyotypes were the same as the parents. In group D, three cases of trisomy 21, three cases of trisomy 18, two cases of extra small chromosome mosaicism and two cases of numerical sex chromosome abnormalities were found. All the mothers in this group were of advanced age. Four cases of structural abnormalities and 22 cases of chromosome polymorphism variations were also found in this group, chromosomal analysis was subsequently performed in those couples, and found that the abnormal chromosomal karyotypes in the fetuses were the same as those in the parents. Conclusions Appropriate prenatal cell genetic diagnostic methods should be chosen according to the causes of abnormal pregnancy history.

Objective: To explore the efficacy of esmolol on cardiac ischemia in patients with serious coronary lesions who are not candidates for coronary revascularizations. Methods: Fifty seven aged patients (34 male) with serious coronary artery disease not candidates for coronary revascularizations were included. All patients had classical angina involved in cardiac ischemia, and definitely ischemic ST-segment depressions in surface electrocardiogram, however which were not relieved by routine treatment including intravenous nitrate or even morphine. All patients received loading dose injection and continuously intravenous infusion of Esmolol, and the baseline characteristics before treatment and the effects at 4 hours after infusion of Esmolol were carefully recorded. Results: After infusion of Esmolol, the ischemia-related symptoms of 41 patients completely relieved, and their ST depressions recovered to the baseline accompanied with significant reduction in blood pressure and heart rate (P＜0.0001 all) within (66±23) min. Moreover, nine patients were observed that their ischemia-related symptoms were relieved and ST alteration recovered partially (P＜0.0001 both) at four h after continuous infusion of esmolol. Conclusion: Esmolol is effective to relieve the serious cardiac ischemia-related symptoms and ST-T alteration of ECG in patients with serious coronary lesions.

Objective:To experimentally intervene safe injection by medical staff in basic-level hospitals and observe the recent and long-term effect atfer the intervention and to provide practical measures to improve safe injection. Methods:We used random sampling methods to set up groups in county hospitals and township hospitals of Hunan Province, and offered lectures, delivered safe injection guide, brochure and on-site guidance in the experimental group. We surveyed the 2 groups atfer the intervention at 1 month and 6 months to compare the effect of unsafe injection behaviors and safe injection behaviors. Results:One month after the intervention, the unsafe injection rate in the experimental group decreased from 27.8%to 21.7%, while in the control group injection the unsafe injection rate rose from 26.0%to 27.9%, with signiifcant difference (P<0.01). Six months atfer the intervention, the unsafe injection rate in the experimental group declined to 18.4%while the unsafe injection rate in the control group also dropped to 22.4%, with signiifcant difference (P<0.01). Unsafe injection rate was decreased in the experimental group at different intervention points, with signiifcant difference (P<0.01). The safe injection behavior scores in the experimental group were higher than those in the control group after the intervention of 1 month and 6 month intervention (P<0.01);the experimental group got higher scores atfer the intervention (P<0.01). Conclusion:Training of safe injection, distribution of safe injection guide, and comprehensive intervention model can significantly change the primary care practitioners’ behaviors in unsafe injections and it is worth promoting.
