AIM: To investigate the efficacy and safety of needle revision with 5-fluorouracil (5-FU) on the dysfunctional filtering blebs after trabeculectomy and to assess the factors that may impact the success.
METHODS:Eighty- three eyes in 76 patients underwent the needle revision and 5-FU subconjunctive injection for the dysfunctional blebs after trabeculectomy and were followed up for 12mo. The intraocular pressure ( IOP), the number of drugs, corneal endothclium, bleb morphology and complications were observed and recorded.
RESULTS: IOP decreased significantly from 35. 3 ±5. 8mmHg(1kPa = 7. 5mmHg) of pre - needling to 17. 0 ±4. 3mmHg of post - needling ( P < 0. 01 ); the average numbers of medications decreased significantly from 1. 7±0. 9 of pre-needing to 0. 4±0. 7 of post-needing (P<0. 01). At 12mo after needling, the success rate of filtering blebs was 89. 2% and the complete success rate was 69. 9%. The Kaplan - Meier survival analysis estimated mean survival period was 11. 0mo (95% CI: 10. 3 - 11. 6). Statistically, there were no significant difference on needling effect with reference to the types of glaucoma, the use of mitomycin C ( MMC ) during the previous filtration surgery, the ages of patients, the intervals of needling operation from previous trabeculectomy, while there were significant difference on needling effect with reference to bleb appearance before needling, and the mean number of needling in patients that had surgery within 3mo were less than those who had surgery for more than 3mo.
CONCLUSION: The needle revision combined with 5-FU is a safe, effective and simple method. Dysfunctional blebs should be treated early after trabeculectomy.

Objective To explore the impact factors for post-thaw embryo survival rate and clinical pregnancy rate in frozen-thawed embryo transfer program. Methods The clinical data of 573 cycles of frozen-thawed embryo transfers were retrospectively analysed. Groups were divided according to the pre-freeze embryo quality, pre-freeze embryonic developmental stage, frozen-thawed embryo quality and cryopreservation technique, respectively, and post-thaw embryo survival rates and/or clinical pregnancy rates were compared among groups. Results The clinical pregnancy rate of high quality pre-freeze embryo was significantly higher than that of low quality pre-freeze embryo (31.8% vs 20.0%) (P< 0.05). There was no significant difference in the post-thaw survival rates and clinical pregnancy rates between embryos frozen at day 2 of ferrtilization and those frozen at day 3 of ferrtilization(79. 1% vs 82.9% and 25.5% vs 31.2%, respectively) (P>0.05). The clinical pregnancy rates of the transfer cycles only with fully intact embryos and with mixed embryos were significantly higher than that only with partially damaged embryos(36.7% vs 24.1% and 29.2% vs 24.1%, respectively)(P<0.05). The post-thaw survival rate and post-thaw high-quality embryo rate were significantly higher in those processed with modified cryopreservation technique than in those processed with original cryopreservation technique (82.0% vs 66.3% and 50.0% vs 27.5%, respectively)(P<0.05). Conclusion Pre-freeze embryo quality, post-thaw embryo survival rate and post-thaw embryo quality have a positive correlation to subsequent clinical pregnancy rate. Favorable cryopreservation technique may ensure the success of post-thaw embryo recovery and transfer.

Firstly discovered in 1980s,human immunodeficiency virus (HIV) continues to affect more and more people.However,there is no effective drug available for the therapy of HIV infection.Betulinic acid existing in various medicinal herbs and fruits exhibits multiple biological effects,especially its outstanding anti-HIV activity,which has drawn the attentions of many pharmacists.Among the derivatives of betulinic acid,some compounds exhibited inhibitory activities at the nanomolar concentration,and have entered phase Ⅱ clinical trials.This paper summarizes the current investigations on the anti-HIV activity of betulinic acid analogues,and provides valuable data for subsequent researches.

Objective:To explore and discuss the differences of pregnancy contents and inform formats in in-formed consent form ( ICF) for the drug clinical trial between China and foreign countries. Methods:We collected Chinese and foreign ICFs for drug clinical trial that had been audited by the Ethics Committee of the third Xiangya Hospital for the past five years. Based on the relevant domestic and foreign law, we concluded the element stand-ards and inform formats about pregnancy inform. By analyzing the integrity of the whole elements, the inform rate of every element and the using rate of every inform format, we compared the differences of pregnancy contents and in-form formats between Chinese ICFs and foreign ICFs. Results:The total number of ICFs was 177 in this study, in-cluding 107 Chinese ICFs and 70 foreign ICFs. The integrity rate of pregnancy in Chinese ICFs was statistically lower than them in foreign ICFs (19% vs. 56%, P=0. 000). Compared with foreign ICFs, the low informed ele-ments were the study of the pregnancy risk (32% vs. 73%, P=0. 000), the pregnancy test during the following-up period (33% vs. 56%, P=0. 002) and the measurements for contraception (22% vs. 53%, P=0. 000). Conclusion:The integrity level of pregnancy content in Chinese ICFs was lower than that of the foreign ICFs. And the three elements including pregnancy risk study, pregnancy test during the following-up period and measure-ments for contraception was obviously defected. Pregnancy informing forms of informed consent in China was inferi-or to abroad.

Objective To explore the role of tissue inhibitor of metalloproteinase-1(TIMP-1) during renal senescence by using human TIMP-1 transgenic mice.Methods Renal histological changes of wild type mice and transgenic mice at the age of 3,12,24 months were observed by periodic acid-schiff(PAS)staining of paraffin sections.The numbers of F4/80 positive cells were detected by immunofluoreseence.The protein expressions of TIMP-1,TIMP-2,matrix metalloproteinase(MMP)-9,MMP-2,intercellular adhesion molecule-1(ICAM-1),transforming growth factor?1(TGF-?1),collagenⅢand collagenⅣwere detected by Western blot.The activities of gelatinases and TIMP-1 were examined by gelatin zymography and reverse zymography respectively.Results Focal renal fibrosis was found in two genotypes with aging.At the age of 24 months,compared with wild type,in kidneys of transgenic type,the expressions and activities of gelatinases were dowregulated (MMP-2:2.08?0.20 vs.3.39?0.43;MMP-9:4.02?0.82 vs.6.72?1.40,all P＜0.05);the expressions of collagenⅢ,collagenⅣ,ICAM-1,and TGF-?1 were upragulated(0.72+0.11 vs.0.57?0.09;0.84?0.13 vs.0.6?0.11,0.72?0.12 vs.0.53?0.07; 0.69?0.12 vs.0.45?0.09,all P＜0.05),and the numbers of F4/80 positive cells were increased (18.8?4.4 vs.12.7?3.6,P＜0.05)with the upregulated expression and activity of TIMP-1(1.10?0.18 vs.0.62?0.09;50.75?7.25 vs.20.64?3.50,P＜0.05).Conclusions TIMP-1 could promote age-related renal fibrosis through enhancing inflammation reaction by ICAM-1 upregulation.

OBJECTIVETo observe the effects of electroacupuncture (EA) on circadian rhythm of temperature and melatonin (MT) in depression rats model induced by chronic stress, so as to explore the biological mechanism of EA for depression.

METHODSTwenty-four SD rats were randomly divided into a control group, a model group and an EA group, 8 cases in each one. Rats in the control group were treated with normal diet for 21 days without any treatment. In the model and EA group, rat model was established by chronic unpredictable stress combined with solitarily feeding method, and rats in the EA group was treated with EA at "Baihui" (GV 20), "Yintang" (GV 29) 1 h before stress stimulation everyday, 2 Hz in frequency and intensity was favorable with the head of rat slightly shivering. The needles were retained for 20 min, once a day for totally 21 days. After EA treatment, open-field experiment was adopted to observe the behavioral improvement; the rats temperatures were monitored at six time points (2:00, 6:00, 10:00, 14:00, 18:00, 22:00) and orbital blood sampling was collected. The level of serum MT was tested by enzyme linked immunosorbent assay. The circadian rhythm changes of temperature and serum MT in each group were compared.

RESULTSThe numbers of horizontal movement and vertical movement in the model group were obviously lower than those in the control group (both P < 0.05), while those in the EA group were significantly improved compared with those in the model group (both P < 0.01). The circadian rhythm of temperature and MT disappeared in the model group, which was improved into normal level after EA treatment.

CONCLUSIONThe electroacupuncture has regulation effects on circadian rhythm of temperature and melatonin in depression rat model induced by chronic stress.

Methods We used stratified random sampling to select 4 schools from each of the categories: kindergartens, primary and secondary schools, colleges and technical secondary schools in Xuhui District in August and September 2019.We used the methods of human landing catch, visual evaluation and ladling to investigate the breeding conditions of mosquitoes and larvaes before and after the beginning of summer semester. Results The mosquito density was 10.50 (per person per time) after the beginning of term, lower than 19.00 (per person per time) before schools opening, and the difference was statistically significant (χ²=4.20, P < 0.05).The positive rate of larvae breeding in small-scale ponds after the beginning of term was 31.47%, lower than 44.23% before the schools opening, and the difference was statistically significant (χ²=4.22, P < 0.05).The positive rate of larval breeding in medium and large static water was 14.00% after the beginning of term, lower than 17.86% before the schools opening, and the difference was no significant (χ²=1.03, P=0.31). Conclusion Schools need to take the following actions: to focus on the work to manage mosquito breeding sites on campus before the beginning of the term; to strengthen the daily work of environment control; to establish a model of prevention and control in cooperation with multi-medical and educational departments, and to form a collaboration system in application of drugs to rain-water catch basin sand in other mosquito control work in residential areas.

Abstract: Objective To analyze and compare the effects of different clinical characteristics on the negative conversion time of nucleic acid detection after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant infection, and to provide a scientific basis for the isolation and treatment of coronavirus disease 2019 (COVID-19). Methods　The epidemiological and clinical data of 228 mild SARS-CoV-2 Omicron variant infected patients diagnosed in Shanghai were retrospectively collected from April 27, 2022 to June 8, 2022 in Wujiaochang designated Hospital, Yangpu District, Shanghai. The negative conversion time of nucleic acid detection was used as the outcome variable, and the patients were divided into A (≤18 days) and B (>18 days). Univariate and multivariate logistic regression analysis were used to analyze the influencing factors of the negative conversion time of nucleic acid detection. Results　The mean nucleic acid conversion time of 228 patients was (18.7±12.1) d, with the median time of 18 (2-46) d. Among them, 120 patients in group A had an average nucleic acid conversion time of (13.2±2.0) d, and 108 cases in group B had an average nucleic acid conversion time of (20.8±1.3) d. Univariate analysis showed that there were no statistically significant differences in the effects of hypertension, coronary heart disease, diabetes, hypokalemia, malignant tumors, neuropsychiatric diseases, chronic digestive diseases on the negative nucleic acid conversion time (P>0.05); however, there were significant differences in the effects of combined cerebrovascular disease, leukopenia, chronic respiratory system diseases and vaccination on the negative nucleic acid conversion time (P<0.05). Further multivariate logistic regression analysis revealed that the combination of chronic respiratory diseases and non-vaccination were significant risk factors for prolongation of negative nucleic acid conversion time (P<0.05). Conclusions The results of this study show that gender, age and whether hypertension, coronary heart disease, diabetes mellitus, hypokalemia, malignant tumor, neuropsychiatric disease and chronic digestive disease have no significant effect on the nucleic acid conversion time, whereas chronic respiratory disease and no vaccination are significantly correlated with the prolongation of nucleic acid conversion time in SARS-CoV-2 Omicron-infected patients.
