Objective To understand the study habits of medical postgraduates in basic cours-es so as to provide references for the reformation of teaching methods. Methods Totally 250 postgra-duates of grade 2010 in our university were investigated with self-made questionnaire. The contents of the questionnaire included basic condition of postgraduates, study methods and suggestions for teaching methods. Rate, percentage and Chi-square test were applied to do statistical analysis. Results Accor-ding to the results of the collected 246 copies of questionnaire, 91.5%(225/246) did not preview lessons before class, 93.5%(230/246) took notes in class, 78.9%(194/246) simply took notes in the book, 60.6%(149/246) preferred more detailed courseware and 27.2%(67/246) reviewed lessons after class. The percentage of simply taking notes in the book of local students (86.5%) was significantly higher than that of army ones (73.2%) (P=0.030), but the percentages of preferring more detailed courseware and reviewing lessons after class of local students were significantly lower than those of army ones (P=0.008, P=0.016). Conclusions The proportion of previewing before class is low among postgrauates. Postgraduates depend heavily on teachers and do not review after class in time. There are differences between local students and army students in taking notes and review habits. It is important to cultivate postgraduates’good study habits.

Objective To compare the effect of pericardial devascularization with that of the modified Sugiura procedure in management of portal hypertension. Methods From 1990 to 2008, 236patients with portal hypertension underwent operations including pericardial devascularization in 147and modified Sugiura in 89 in our hospital. Results There were 12 perioperative deaths (8.2 % ), and 2 rebleedings (2 % ) in the pericardial devascularization group, and 7 perioperative deaths (7.9 % ) and 2 rebleedings(3.4 % ) in the modified Sugiura group. The follow-up rate was 91.9 % in the pericardial devascularization group and 87.8% in the modified Sugiura group respectively, in a period from 6 months to 19 years. The 1-, 3-and 5-year rebleeding rates were 5.7%,15.2% and 25.5% in the pericardial devascularization group and 6.9%, 16.3%, 29.5 % in the modified Sugiura group, respectively. The 1-, 3- and 5-year survival rates were 87.8% ,79.1% and 69.7% in the pericardial devascularization group and 95.8 %,85.0%, 76.9 % in the modified Sugiura group, respectively. Conclusion Modified Sugiura procedure and pericardial devascularization have differences in perioperative mortality as well as rebleeding and survival rates.

OBJECTIVETo study the effects of dosages of total body irradiation on the healing process of cutaneous wounds and to observe the changes of wound area at different periods after injury.

METHODSThe entire body irradiation from a (60)Co gamma-ray source was performed on Wistar rats. The single dosage varied from 1 to 8 Gy. Within 1 h after irradiation, two whole thickness circular cutaneous wounds corresponding to 2.5% of total body surface area (Phi = 22 mm) were produced on the back of the animals (combined injury groups). Same wounds were produced on rats with no irradiation (single wound group). Wound healing was observed at different points after injury.

RESULTSAfter total body irradiation with the dose of 1, 2, 3, 4, 5, 6, 7 or 8 Gy, the wound healing was obviously retarded as the dosages increased. The wound area remained was larger in the large dosage groups than in the small dosage groups. Seven days after injury, there was 33.5% wound surface left unhealed in the single wound group, whereas in the combined injury groups, 35.4%, 38.1%, 41.6%, 48.8%, 53.9%, 63.7%, 69.2% and 73.9% of the wound surfaces remained unhealed, respectively. Statistical analysis showed marked correlations between the various times after total body irradiation and various dosages to the percentage of unhealed wound surface. Nine dose-effect relation formulae were deduced according to the statistical results.

CONCLUSIONSIn soft tissue trauma combined with radiation injury, the delay of wound healing is related to the dose of radiation inflicted. It is also related to the time between injury and time of observation.

OBJECTIVE To reevaluate the system atic evaluation of g emcitabine combined with cisplatin in the treatment of advanced non-small cell lung cancer （NSCLC），in order to provide evidence-based evidence for the treatment of NSCLC. METHODS Retrieved from Wanfang database ，CNKI，VIP，PubMed，Embase，systematic evaluation of gemcitabine combined with cisplatin versus pemetrexed/vinorelbine combined with cisplatin in the treatment of advanced NSCLC was included from the inception to Dec. 2021. RevMan 5.3 system evaluation software was used for meta-analysis of various outcome indicators ； AMSTAR2 scale was used for methodological quality evaluation ，and GRADE tool was used for evidence quality evaluation. RESULTS A total of 9 literatures were included. Meta-analysis showed that the effective rate of gemcitabine combined with cisplatin was significantly lower than pemetrexed combined with cisplatin ，but was similar to vinorelbine combined with cisplatin. The 1-year survival rate of gemcitabine combined with cisplatin was equivalent to that of pemetrexed combined with cisplatin ，but was superior to vinorelbine combined with cisplatin. There was no significant difference in the incidence of nausea and vomiting between gemcitabine combined with cisplatin and pemetrexed/vinorelbine combined with cisplatin. Gemcitabine combined with cisplatin had a higher incidence of thrombocytopenia than pemetrexed/vinorelbine combined with cisplatin. The incidence of neutropenia and leukopenia in gemcitabine combined with cisplatin were higher than pemetrexed combined with cisplatin ，but were significantly lower than vinorelbine combined with cisplatin. The evaluation results of AMSTAR 2 scale showed that 6 systematic evaluation were of low quality in methodology and 3 were of very low quality. The results of the GRADE tool showed that 31％ of the outcome indicators were of medium quality （14 items），27％ were of low quality （12 items），and 42％ were of very low quality（19 items）. Research limitations and publication bias were the most frequently downgraded factors. CONCLUSIONS Gemcitabine combined with cisplatin has advantages over 154854280@qq.com vinorelbine combined with cisplatin in the efficacy and safety of ad vanced NSCLC ，especially in the 1-year survival rate ，the incidence of neutropenia and leucopenia. The efficacy and safety of gemcitabine combined with cisplatin are inferior to those of pemetrexed combined with cisplatin. However ，the methodological quality and evidence level of systematic evaluation are not high on the whole ，and the overall quality of research needs to be improved.

OBJECTIVE To provide reference for improving the dispensing accuracy of similar drugs and reducing dispensing error risk through exploring the dispensing mode of similar drugs. METHODS The effectiveness and feasibility of the similar drug dispensing management mode was explored through adjusting the traditional horizontal or vertical sorting method to a “Z” shaped cargo location sorting， implementing similar drug in different zones dispensed by different people， and combining measures such as adjusting the format of drug dispensing documents and improving inventory methods. The role of similar drug dispensing mode in drug dispensing management was evaluated comprehensively from two aspects： work quality and work efficiency. RESULTS After the implementation of similar drug dispensing mode， total number of monthly dispensing errors （18.42±8.79 vs. 28.50±6.87，P= 0.005） and the proportion of monthly dispensing errors of similar drugs （[ 4.17±5.71）% vs. （10.96±7.05）%，P＝0.017] were significantly lower than before the implementation； the monthly consistency rate between accounts and materials （[ 98.46±0.73）% vs. （97.61±0.57）%， P＝0.004] was significantly higher than before implementation； completion time of dispensing in each batch was not significantly affected， and daily work was carried out smoothly and orderly. CONCLUSIONS The similar drug dispensing mode has a significant effect in improving the accuracy of dispensing similar drugs， reducing the risk of dispensing errors， and does not affect the efficiency of dispensing work.

OBJECTIVE To systematically evaluate the adverse effects of drug-resistant tuberculosis （DR-TB） drugs on pregnant women and fetuses ，so as to provide evidence-based reference for clinical medication. METHODS PubMed，Cochrane Library，Embase，CBM，CNKI，Wanfang database and VIP were searched by computer to collect randomized controlled trials （RCTs），cohort studies ，case-control studies ，case series and case reports about pregnant women exposed to DR-TB drugs. The retrieval time limit was from the establishment of each database to August 20，2021. After selecting the literature and extracting the data，the bias risk assessment tool recommended by 6.2 version of Cochrane system evaluator manual was used to evaluate the quality of the included RCTs ；Newcastle-Ottawa scale was used to evaluate the quality of the included cohort studies and case-control studies ；IHE scale issued by the Canadian Institute of Health Economics （IHE）was used to evaluate the quality of the included case series and case reports. RevMan 5.1 software was used for Meta-analysis of non-comparative binary data. RESULTS A total of 13 literature were included ，including 7 case series and 6 case reports ，involving 203 patients and 204 newborns；among them，there were 6 literature about non-comparative binary data. The results of meta-analysis showed that after exposure to DR-TB drugs，no newborn had birth defects ；the mortality of pregnant women was 0.09[95％CI（0.06，0.15），P＜0.000 01]；the neonatal mortality was 0.02[95％CI（0，0.06），P＜0.000 01]；the incidence of preterm birth was 0.14[95％CI（0.03，0.43），P＝0.02]；the incidence of infants with low birth weight was 0.17[95％CI（0.04，0.51），P＝0.06]；the incidence of growth retardation was 0.15[95％CI（0.09，0.22），P＜0.000 01]；the incidence of stillbirth was 0.05[95％CI（0.02，0.09），P＜0.000 01]；the incidence of abortion was 0.08[95％CI（0.05，0.14），P＜0.000 01]. CONCLUSIONS Pregnant women exposed to DR-TB drugs can cause pregnant women ’s death and abortion ，neonatal death ，premature birth ，infants with low birth weight ，growth retardation and stillbirth，but there is no neonatal birth defect ；these adverse outcomes may be related to the history of DR-TB.
