Objective To explore the pancreatic kininogenase enteric-coated tablets in the treatment of diabetic retinopathy (DR) patients and its effect on the optic disc and macula retinal hemodynamics. Methods 86 cases (140 eyes) of DR patients were randomly divided into pancreatic kininogenase group and normal group with 43 cases in each group, two groups were treated with basic therapy, pancreatic kininogenase group were combined with pancreatic kininogenase treatment. The best corrected visual acuity and the clinical effect of optic disc and macula retinal hemodynamic changes were compared between two groups. Results After treatment, the best corrected visual acuity (BCVA) in pancreatic kininogenase group was greater than the normal group (P<0.05), the retinal neovascularization and fluorescein leakage area in pancreatic kininogenase group was less than the normal group (P<0.05). The disc vascular and macular retinal blood flow volume (VOL), blood flow velocity (FLW)values in pancreatic kininogenase group were larger than those of normal group, and the clinical curative effect of pancreatic kininogenase group was better than that of normal group (P<0.05). Conclusion Pancreatic kininogenase enteric-coated tablets in the treatment of DR patients can improve the optic disc and macular retinal hemodynamic parameters, improve visual acuity and reduce the retinal neovascularization and fluorescein leakage area, so as to improve the clinical treatment effect.

Objective To explore the curative effect of modified closed negative pressure drainage on abnormal abdominal incision. Methods Sity-three patients with abnormal healing of abdominal incision in our hospital from January 2012 to June 2013 were selected as the observation group. Another 50 patients from January to December 2011 were assigned to the control group. The former was treated after debridement with human recombinant surface growth factor and modified closed negative pressure drainage,while the latter after debridement with anti-infection and dressings of ethacridine or gentamicinsolution as well as with infrared therapy. The two groups were compared in terms of the frequency,time and cost of changed dressings,and the healing time of the incisions.Results There was insignificant difference in the cost of changed dressings between the two groups(P>0.05). However,the differences were statistically significant in terms of the frequency and time of changed dressings and the healing time of the incisions(P<0.05). The observation group was significantly superior to the control group.Conclusions Modified closed negative pressure drainage is effective in accelerating the healing in abnormal abdominal incisions,reducing the frequency and the time of changed dressings,and easing the economic burdens of the patients,which is suggested to be popularized and applicable in the pimary hospitals.

Objective To investigate immunogenicity and protection efficacy of the recombinant hypoxanthine-guanine-xanthine (HGXPRT) of Plasmodium falciparum expressed in Pichia pastoris. Methods 35 BALB/c mice were divided randomly into five groups: HGXPRT+ISA720 experiment group, HGXPRT+Freund experiment group, ISA720 adjuvant control group, Freund adjuvant control group, and blank control group. BALB/c mice were subcutaneously immunized three times with the HGXPRT protein formulated by either Freund or ISA720 adjuvants at a three weeks interval. Mice were bled via tail vein at 2 weeks after each immunization. Specific antibodies were detected by ELISA as well as IFAT using cultured parasites. The immunized mice were challenged with 105 P.yoelii 10 days after the third immunization and parasitemia was monitored daily by examining Giemsa-stained thin film. Results Strong immune response was induced by the HGXPRT antigen formulated with the adjuvant. Antibody titers of more than 1∶105 were detected after the third immunization while no specific antibody was detected in the mice immunized with adjuvants only. The antibodies against HGXPRT recognized the cultured parasite by IFAT. Four days after mice were challenged with P.yoelii, high parasitemia appeared in the two control groups, which were 24 h earlier than experiment groups. The mean parasitemia of HGXPRT+ISA720 experiment group(29.3%) was significantly lower than that of control groups (70.0%) (P

Objective To observe the curative effect and prognosis of cough variance asthma(CVA) evoked by mycoplasma pneumonia(MP) treated by azithromycin combined with pumicort and bricasol.Methods 126 CVAs evoked by MP were divided randomly into two groups:the therapeutic group,were given azithromycin orally and inhaled pumicort and bricasol,the control group,were treated only by azithromycin orally.The remission rate and recurrence rate of cough between the two groups were compared.Results The remission rate and recurrence rate of cough of therapeutic group were 100% and 15.9% respectively while those of the control group were 28.6% and 60.3% respectively.The difference between two groups was significant.Conclusion Azithromycin combined with pumicort and bricasol can improve significantly the curative effect of CVA evoked by MP,decrease the recurrence and make for the prognosis.

Objective To investigate the effect of pregnancy on the potency of bupivacaine for spinal anesthesia in rats. Methods Female non-pregnant SD rats weighing 180-220 g and 17 day pregnant SD rats weighing 350-400 g were used in this study. The rats ( 18 non-pregnant, 18 pregnant) in which PE-10 catheter were successfully placed without complications were selected. The 18 non-pregnant rats were randomly divided into 3 groups (n =6 each): control group (group C), 2% bupivacaine group (group B2 ) and 4% bupivacaine group (group B4). The 18 pregnant rats were also randomly divided into 3 groups (n = 6 each): control group (group PC),2% bupivacaine group (group PB2 ) and 4% bupivacaine group (group PB4 ). Group C and PC received intrathecal (IT) normal saline 30 μl, and the other 4 groups received 2% or 4% bupivacaine 30 μl intrathecally. Analgesia was determined using the taifllick latency (TFL) before IT administration (baseline), and at 10 min, 20 min,30 min, 1 h, 2 h, 4 h, 1 d, 2 d, 3 d and 4 d after IT administtation. The percentage of the maximal possible effect (MPE) was calculated. Hind-limb motor function (MF) was also assessed. Results Compared with the baseline value, MPE at 10 min-2 h after administration and MF scores at 10 min-1 h after administration were significantly increased in group B2, MPE at 10 min-4 h after administration and MF scores at 10 min-1 h after administration were significantly increased in group B4;MPE at 10 min-1 d after administration and MF scores at 10 min2 h were significantly increased in group PB2 and MPE at 10 min-1 d after administration and MF scores at 10 min4 h were significantly increased in group PB4 ( P ＜ 0.05 ). Conclusion Pregnancy can enhance the potency of bupivacaine for spinal anesthesia in rats.

Objectives To investigate the overall prevalence of cardiovascular disease (CVD) in subjects hospitalized for chronic obstructive pulmonary disease (COPD),and explore the prevalence of the major CVD complications and trends in patients with COPD over a 10-year period.Methods Medical records in the PLA General Hospital,Beijing Union Medical College Hospital,and Beijing Hospital from 2000/01/01 to 2010/03/03 were retrospectively reviewed.A total of 4960 patients with COPD were reviewed in the study (3570 males,mean age,72.2 ± 10.5 years; 1390 females,mean age,72.0 ± 10.4 years).Results The prevalence of CVD in COPD patients was 51.7％.The three most prevalent CVDs were ischemic heart disease (28.9％),heart failure (19.6％),and arrhythmia (12.6％).During the 10-year study period,the prevalence of various CVDs in COPD patients showed a gradual increasing trend with increasing age.There was higher morbidity due to ischemic heart disease (P ＜ 0.01) in male COPD patients than in the female counterparts.However,heart failure (P ＜ 0.01)and hypertension (P ＜ 0.01) occurred less frequently in male COPD patients than in female COPD patients.Furthermore,the prevalence of ischemic heart disease decreased year by year.In addition to heart failure,various types of CVD complications in COPD patients tended to occur in younger subjects.The prevalence of all major types of CVD in women tended to increase year by year.Conclusions The prevalence of CVD in patients hospitalized for COPD in Beijing was high.Age,sex and CVD trends,as well as life style changes,should be considered when prevention and control strategies are formulated.
