After operation, a round p upil was obtained in 19 eyes (90.5%) and an irregular pupil in 2 eyes (9.5%).Conclusion　This operation is suitable for complicated cataract se condary to uveitis, and worth to popularize due to the minimization of iris dam age and postoperative inflammation in the anterior chamber, good visual acuity r ehabilitation earlier.

OBJECTIVETo develop and evaluate an individualized fluid therapy in the elderly patients with coronary heart disease undergoing gastrointestinal surgery.

METHODSIn this prospective study, 60 coronary heart disease patients undergoing gastrointestinal surgery were included in the First Affiliated Hospital of Xinjiang Medical University from March 2009 to March 2012. Patients were randomized into the intervention group and the control group with 30 patients in each group. Individualized fluid therapy was used during surgery and postoperative period in the ICU, which was determined based on target controlled fluid therapy according to cardiac index, stroke volume, and stroke volume variation. Traditional fluid therapy was used in the control group in the intraoperative and postoperative period. The two groups were compared in terms of postoperative hemodynamic parameters, total fluid volume, incidence of adverse cardiac events, and recovery of bowel function.

RESULTSCompared with the control group, mean arterial pressure was significantly increased at the commencement of the surgery. The cardiac index was significantly elevated during surgery and at the end of the surgery. Stroke volume was significantly increased after induction of anesthesia, during the surgery, and at the early stay of ICU period(all P<0.05). Serum lactic acid in the intervention group was significantly lower at the end of surgery and during ICU stay than that in the control group (all P<0.05). During surgery and 24-hour stay in ICU, the total fluid volume, crystal usage, and urine were significantly less, while colloidal fluid use was significantly more in the intervention group as compared to the control group(all P<0.05). The perioperative adverse cardiac event rate was 36.7%(11/30) in the intervention group, lower than 56.7%(17/30) in the control group, but the difference was no statistically significance(P>0.05). In the intervention group, defecation time, time to first flatus, resumption of liquid intake, length of ICU stay and hospital stay were significantly less compared with the control group(P<0.05).

CONCLUSIONIn the elderly patients with coronary arterial disease undergoing gastrointestinal surgery, individualized fluid therapy can effectively decrease adverse cardiac events, improve postoperative gastrointestinal function, and reduce length of hospital stay.

OBJECTIVETo assess the extent and relative changes of the equities in prenatal care utilization among women with different educational attainment in some areas of China.

METHODSData were collected in 13 counties/cities covered by Perinatal Health Care Surveillance System established by Institute of Reproductive and Child Health, Peking University. The study population consisted of 103 704 women who delivered single live births in 1994 and 2000. Chi-square and multiple logistic regression were employed to compare the systematic management rates and relative risks. Concentration index was used to assess the relative changes of equities in prenatal care utilization. SPSS 11.5 and Microsoft Excel 2003 were used for analysis.

RESULTSThe total systematic management rate was 22.1% in 1994 and 57.4% in 2000. The concentration index was -0.046 in 1994 and 0.066 in 2000. In northern areas, the concentration index increased from 0.015 in 1994 to 0.295 in 2000, while it increased from -0.015 in 1994 to 0.062 in 2000 in southern areas. In rural areas, the concentration index increased from 0.002 in 1994 to 0.026 in 2000, while it decreased from 0.042 in 1994 to 0.019 in 2000 in urban areas.

CONCLUSIONInequities in prenatal care utilization in 2000 become more obvious than in 1994, especially in northern areas. More attention should be paid to solve the inequities.

Objective To study the current status of spontaneous abortion of primigravid women in Jiaxing areas of Zhejiang province of China. Methods We analyzed the data from both perinatal healthcare surveillance program and spontaneous abortion, collected in Jiaxing areas by the Institute of Reproductive and Child Health, Peking University. The study population consisted of 14 769 primigravid women (excluding induced abortion, ectopic pregnancy and molar pregnancy as outcomes) attempting to become pregnant who registered between 1993 and 1995. Results 1454 spontaneous abortion cases were identified, with the spontaneous abortion rate as 9.8% (95% CI:9.3%-10.3%). The mean gestational weeks at pregnancy diagnosis were 7.6±2.1 weeks, the mean gestational weeks at miscarriage were (10.1±3.1) weeks and the incidence of first-trimester (≤12 weeks) spontaneous abortion was 7.3%(95%CI: 6.8%-7.7%), accounting for 73.7% of all the spontaneous abortion cases. A peak for risk of miscarriage was around 8-13 weeks, accounting for 37.7% of all spontaneous abortion. The observed multiple Cox regression model showed that increased spontaneous abortion rates were observed in women with age at pregnancy ≥30, being peasants and with higher education level. Conclusion The spontaneous abortion rate of primigravid women in Jiaxing areas was higher than in other areas of China. The maximum occurrence of spontaneous abortions was during period of 8-13 gestation weeks.

Objective To explore a more objective scheme for comprehensive evaluation of township health education program. Methods Based on the indicators and grading results of 17 township hospitals (named from A to Q) in Xiangshan County, we calculated the weight of each indicator by entropy weight method and sorted the township hospitals by the improved TOPSIS. Then we compared the ranking with the annual assessment results in 2017 to verify the rationality of this scheme. Results The entropy weights of"printed materials of health education","play of audio-visual materials","health education bulletin board","public health consultation" ,"health knowledge lecture" ,"individualized health education" and"awareness rate of health knowledge"were 0.122 0, 0.125 3, 0.134 6, 0.157 2, 0.157 0, 0.179 8 and 0.124 1, respectively. Through the improved TOPSIS, 17 hospitals were sorted as follows: P, L, O, C, G, A, H, N, B, E, M, Q, K, J, F, D, I. Compared with the annual assessment rankings which were P, L, A, C, B, O, G, H, K, N, D, E, M, J, I, F, Q, thirteen of them were different. Conclusion "Printed materials of health education","awareness rate of health knowledge" and"play of audio-visual materials" have little room for improvement, while"individualized health education" should be focused on in the future. The improved TOPSIS based on entropy weight could objectively evaluate the quality of health education service.
