AIM: To observe the effect of intraocular lens ( IOL) implantation on visual acuity and contrast sensitivity in patients with cataract.
METHODS: Fifty - eight cases ( 72 eyes ) cataract patients with regular cornel astigmatism, in our hospital from May 2014 to May 2015 were randomly divided into two groups to undergo phacoemulsification and IOL implantation: the observation group: 29 cases (36 eyes) received multifocal toric IOL implantation; the control group: 29 cases (36 eyes) received monofocal toric IOL implantation. Uncorrected distance visual acuity ( UCDVA), uncorrected near visual acuity ( UCNVA), best corrected distance visual acuity (BCDVA), the best corrected near visual acuity ( BCNVA ), total eye astigmatism, and the dark contrast sensitivity were observed for these patients at 1 and 6mo after cataract surgery.
RESULTS: There were no statistical significant difference between the two groups at postoperative 1, 6mo on UCDVA, BCNVA, BCDVA and total eye astigmatism(P>0. 05). UCNVA of observation group at 1 and 6mo were better than those of control group ( P <0. 05); there were statistically significant difference in high frequency comparison at the sixth postoperative months (P<0. 05).
CONCLUSION: Both monofocal toric IOL implantation, and aspheric multifocal toric IOL implantation for cataract with regular corneal astigmatism are effective to improve visual acuity. But the latter treatment would contribute to the improvement of uncorrected near visual acuity and the dark contrast sensitivity.

Objective: To learn the characteristics of adolescent pregnancy in Wenzhou from 2015 to 2019, so as to provide basis for protecting adolescent physical and mental health. Methods: Data of demographic characteristics, pregnancy and delivery outcomes of the women aged under 19 years ( adolescent pregnant ) and 20 to 34 years ( right-age pregnant ) who delivered in Wenzhou from 2015 to 2019 were collected from Wenzhou Maternal and Child Health Information Management System. The incidence of pregnancy complication, comorbidity and adverse delivery outcomes of adolescent pregnant women was compared with that of right-age pregnant women. Results: Among 536 753 parturients reported in Wenzhou from 2015 to 2019, there were 22 419 ( 4.18% ) of adolescent pregnancy and 430 163 ( 80.14% ) of right-age pregnancy. The average age of adolescent pregnant women was (18.11±0.82) years ( range, 10-19 years ). The majority of adolescent pregnant women were migrant population (19 437 cases, 86.70%), had an education level of junior high school and below ( 18 594 cases, 82.94% ), and had no occupation (19 192 cases, 85.61%). The incidence rates of anemia, gestational diabetes, postpartum hemorrhage, perineal laceration and premature delivery in adolescent pregnant women increased from 2015 to 2019 ( all P<0.05 ). The incidence rates of gestational diabetes, anemia, gestational hypertension, placental abruption, postpartum hemorrhage, perineal laceration, premature delivery, low birth weight, fetal death and stillbirth were 1.65%, 11.76%, 0.19%, 0.26%, 3.19%, 24.52%, 6.03%, 5.53%, 0.50% and 0.04% in adolescent pregnant women, which were significant different from 5.49%, 8.94%, 0.13%, 0.01%, 0.17%, 23.46%, 4.66%, 3.08%, 0.26% and 0.01% in the right-age pregnant women, respectively ( all P<0.05 ). Conclusions The adolescent pregnant population in Wenzhou are mainly migrant population with lower education level and no occupation. The incidence rates of pregnancy complication, comorbidity and adverse birth outcomes in adolescent pregnant population are higher than those in right-age pregnant population, and are increasing year by year.

Objective To assess the current status of knowledge, attitude and practice (KAP) towards antibiotic use among community residents in Hangzhou, and to explore the correlations among them. Methods A total of 449 permanent residents in Hangzhou were randomly selected using a multistage stratified random sampling method. Self-reported data on basic demographic factors, and relevant KAP information were collected by the questionnaire survey. Differences in KAP scores according to each demographic factor were assessed by the t test or ANOVA test, and AMOS 21.0 was used for the path analysis. Results Scores for knowledge, attitude and practice regarding antibiotic use were (6.17±2.45), (6.45±0.99) and (6.21±1.02) respectively. Results of the path analysis showed that education level and age had effects on the knowledge (coefficients: 0.57 and -0.38 respectively) . Age, gender and knowledge had effects on the attitude (coefficients: -0.27, 0.12 和 0.02 respectively), and attitudes, gender, monthly income and the level of education had effects on the practice (coefficients: 0.48、 0.37、 0.06 and 0.02 respectively) . Conclusion Community residents in Hangzhou lack relevant knowledge, and there are some irrational attitudes and practices regarding antibiotic use. There is a correlation between knowledge and attitudes, as well as between attitudes and practices, but the knowledge and practices are not correlated.

The protoplasts of original Aspergillus niger strain Uco-3 were treated with the cooperation of UV and ?-ray to obtain the high-yielding strain producing the thermostable ?-galactosidase. Under the optimum conditions of formation and regeneration protoplasts were prepared. According to the interaction of positive mutation rate and radiation dose,the optimum condition was determined. The optimum dose of UV was 4 minutes and the optimum dose of ?-ray was 500 Gy. After mutagenetic treatment of protoplasts and selection from a lot of mutants,a mutant DL116 producing the thermostable ?-galactosidase was obtained. The ?-galactosidase activity of DL116 was increased from 16.27 U/mL to 44.37 U/mL,which was higher than that of strain Uco-3.

AIMTo prepare nifedipine (NP) rapid release mini-tablet, sustained release mini-tablets, pulsed release mini-tablets and delayed-onset sustained release mini-tablets and develop multiplied pulsed drug delivery system (DDS), site-specific DDS, zero-order DDS and quick/slow DDS by various ways.

METHODSVelocity-time (v-t) equation of each mini-tablet was deduced by non-linear least square model fit. The difference of combinations in v-t profiles between theoretical value and test value was compared.

RESULTSAccording to the v-t equations, the combined release behaviors were observed directly from v-t profiles and the test values coincided with the theoretical profiles.

CONCLUSIONThe programmed DDS, which consist of a variety of mini-tablets with different dosages and combinations in capsules, could be predicted by summing up the v-t equation of each tablet.
