Objective To evaluate the effect of bandage rollers compression on pocket hemostasis in patients after implantation of permanent pacemaker.Methods A total of 591 patients after implantation of permanent pacemaker were enrolled in this study and divided into trial group and control group.The wounds of 296 patients in trial group received compression by two bandage rollers,which were placed parallelly on the wound side by side,above the pocket of pacemaker,fixed by 3M adhesive tapes so that no bleeding of wound and no shifting of rollers.6 hours after the operation,the tapes and bandage rollers were released.The wounds of 295 patients in control group received compression by 1 000 g sand bag which were taken off 6 hours after the operation.The safety and effects of hemostasis in patients between the two groups were compared.Results The incidences of incision bleeding,pocket hematoma and pocket skin pressure injury were not significantly different between the two groups(P>0.05).The incidences of postoperative pain,urinary retention and insomnia were significantly different between the two groups(P<0.05).Conclusion The incidences of postoperative pain,urinary retention and insomnia are significantly reduced in patients who received bandage roller compression.

Background:NLRP3 inflammasome attracts widespread attention in study of inflammatory bowel disease. Faecalibacterium prausnitzii(Fp)is an anti-inflammatory commensal bacterium that has preventive and therapeutic effects on rat colitis. Aims:To explore the underlying mechanism of Fp in treating experimental colitis in rats. Methods:Fifty rats were randomly divided into two groups,10 in control group and 40 in model group. Rats in model group were administered intrarectally with 5% TNBS and dehydrated alcohol to induce experimental colitis. Twenty-four hours afterwards,the model rats were further divided into four groups and administered intragastrically with PBS,culture medium,live Fp and Fp supernatant 1 mL per day,respectively,for 7 days. On day 8,all the rats were sacrificed for evaluation of colonic inflammation. Expressions of the constituents of NLRP3 inflammasome(NLRP3,ASC,and caspase-1)were assessed by Western blotting and real-time PCR;levels of IL-1β and IL-18,the downstream effectors of NLRP3 inflammasome,in colon and plasma were measured by real-time PCR and ELISA,respectively. Results:Weight loss, reduced colon length and colonic inflammatory injury were observed in model rats. These manifestations were ameliorated in live Fp and Fp supernatant groups than those in PBS and culture medium groups. In PBS and culture medium groups, expressions of NLRP3,ASC,and caspase-1 protein and mRNA in colonic tissue were significantly higher than those in control group(P < 0. 05),the colonic and plasma levels of IL-1β were increased(P < 0. 05),and IL-18 levels were decreased(P < 0. 05). In live Fp and Fp supernatant groups,IL-18 level showed a further reduction as compared with PBS and culture medium groups( P < 0. 05),but the increasing trend for other parameters was reduced( P < 0. 05). Conclusions:NLRP3 inflammasome participates in the development of TNBS-induced colitis in rats. Fp might alleviate colonic inflammation by inhibiting NLRP3 inflammasome and its downstream effectors.

Objective:To study the frequency and distribution of HLA-A alleles and HLA-A*02 subtypes in the lung cancer patients in Yunnan Xuanwei area.This study aims at providing the significant genetic information for lung cancer research and treatment.Methods:Genomic DNA samples were collected from lung cancer patients and healthy donors residing in Yunnan Xuanwei area.HLA-A alleles and HlA-A*02 subtypes were typed by PCR-SSP assay.Case-control study was used to study the difference of frequency distribution between patients and normal controls.The polymorphisms of HLA-A*02 were also observed in cancer patients.Results:The positive rates of HLA-A*02 was significantly higher in cancer patients than in healthy controls (P=0.004,OR=2.432,95% CI=1.314-4.500),which were 68.75% and 47.50%,respectively.The gene frequency of HLA-A*02 was significantly higher in cancer patients than in healthy controls(P

AIM: To observe the comparison of vitrectomy combined drug therapy ( Ranibizumab injection ) and single vitrectomy for proliferatived diabetic retinopathy ( PDR ) and the influence of the curative effect and prognosis of patients.
METHODS:In this study, 112 cases (125 eyes) with PDR were selected and randomly divided into experimental group and control group ( n= 56 ) . Fifty-six cases ( 61 eyes ) in experimental group were injected by drug therapy of 0. 5mg ranibizumab and received vitrectomy;In control group, 56 cases ( 64 eyes ) were received single vitrectomy. The intraoperative and postoperative differences of clinical indicators were analyzed in two groups.
RESULTS: The average operation time, intraoperative electric coagulation hemostasis rate and iatrogenic hiatal incidence of the experimental group were lower than that of the control group:(95. 00±13. 00) min vs (133. 00±14.5) min, 11% vs 34%, 5% vs 20%, respectively (P<0. 05). The anterior chamber and vitreous body cavity hemorrhage rate within postoperative 1mo in the experimental group were lower than that of the control group:7% vs 23%, 5% vs 12%, respectively (P<0. 05). The postoperative visual acuity of experimental group was better than that of the control group:0. 375±0. 210 vs 0. 261±0. 170, respectively (P<0. 05).
CONCLUSION: Patients with PDR injected with ranibizumab in vitreous cavity before vitrectomy can effectively reduce the operation time, less intraoperative blood loss, the incidence of iatrogenic hiatus, and intraoperative and postoperative complications. The postoperative visual acuity was better than before.

Objective To understand the cognition of clinical medical postgraduates' professional ethics,in order to provide the basis for the further development of graduate professional ethics education.Methods The survey was carried out among 650 graduate students of the first hospital of Jilin University by self-designed questionnaires.The questionnaires included the general situation and the understanding of professional ethics of medicine.All data were analyzed by SPSS 17.0,using Chi-square test to compare the results in different grades about the understanding of professional ethics.Results In this study,a total of 650 questionnaires were issued,and 629 valid questionnaires were collected with a recovery rate of 96.7％.Most graduates' professional values were in line with the socialist core values.For example,for the attitude of medical workers to accept red envelopes,410 graduate students (65.2％) firmly opposed to accepting this behavior.For the purpose of the study medicine,there was no statistically significant difference among different grades (P=0.273).For the attitude of red paper,the main problem in medical ethics education and the biggest factor for graduates,there was statistically significant difference among different grades (P=0.012,P=0.002,P=0.002,respectively).Conclusion At present,the professional ethics of postgraduates in clinical medicine is in good condition,but still needs to be improved.We can give further education and guidance to students for the problems existing in graduate students of different grades.
