Objective To study the safety, efficiency and efficacy economics of local application of domestic fluconazole in treatment of chronic obstruction pulmonary disease (COPD) complicated with oral candidiasis. Methods Selected 74 patients with chronic obstruction pulmonary disease (COPD) complicated with oral candidiasis from May, 2013 to Oct. 2015 in our hospital were divided into the observation group in 35 cases and the control group in 39 cases according to table of random number. The observation group was given local application of domestic fluconazole, and the control group was given systemic application of imported fluconazole. The clinical effects and side effects of both groups were observed and compared. Results The total effect rate in observation group (100%) was higher than that in the control group (97.4%) without significant difference (P > 0.05). The cute rate in observation group (94.3%) was higher than that in control group (87.2.4%) without significant difference (P > 0.05). The average course of treatment was shorter in the observation group (2.9 d) than that in control group(5.2 d), with significant difference (P < 0.01). The observation group had no adverse reaction and the control group had 5.1% (P > 0.05). The cost of antifungal drugs in the observation group was lower than that in the control group, (t = -23.398, P = 0.000). The cost-effectiveness ratio in the observation group was lower than that in the control group. Conclusion Local application of domestic fluconazole has similar effect and side effect to systemic application of imported fluconazole in treatment of COPD complicated with oral candidiasis,but has short course of treatment and low cost .

Objective:The causes, management, and prevention of complications in laparoscopic gyneco-logic surgery were investigated. Methods:A retrospective analysis was done based on clinical data of 8279 cases of laparoscopic gynecologic surgery from January 1996 to December 2008 in this hospital. Results:The complication rate was 0.88% (73/8279). These included five cases intraperitoneal bleeding, five cases injury of ureter, 20 cases abdominal vessel damage, 10 cases vulva emphysema, 25 cases wound healing delay and each one case respectively for stomach injury, bladder injury, secondary abdominal cavity preg-nancy,infection and incision hernia. The occurrence rates of complications between hysteroscopy combined with laparoscopic surgery and pure adnexal surgery were no difference( P >0.05). Compared to adnexal op-erations, there was a significantly higher complication rate in myomectomy and laparoscopic assistant vaginal hysterectomy (P < 0.01 ). Conclusions:Complications of laparoscopic gynecologic surgery are correlated with the difficulty of operation and the skillfulness of operators. In order to reduce complications, careful oper-ation and avoiding over self -confidence are essential.

Objective To investigate the effects of different penetration enhancers on percutaneous absorption of Xiaoyan Runma mucilage in vitro, and to improve the curative efficacy of this mucilages through selection of the effective penetration enhancers. Methods Xiaoyan Runma mucilage was prepared with different penetration enhancers. An intelligent permeability instrument was used for in vitro percutaneous absorption test of rats , with isolated mice abdomen skin serving as in vitro transdermal barrier and saline isotonic solution as receptor fluid. Then the contents of lidocaine hydrochloride in receptors were determined by HPLC.The accumulative transit dose (Q) and percutaneous permeability (J) within 12 h were calculated and compared with those of mucilage without any enhancer. Results With Q value serving as an index, different enhancers had different promote permeation effects on Xiaoyan Runma mucilage, and the effects in descending order were as follows:4% azone [(222.75±3.4) μg?(cm2)-1]>2% azone[(207.42±5.1) μg?(cm2)-1]>3% menthol [(183.38±4.9) μg?(cm2)-1]>5%menthol [(160.82±5.4) μg?(cm2)-1]>2% azone+3% menthol [(151.25±5.5) μg?(cm2)-1]>2% azone+5% isopropyl myristate [(127.26±7.1) μg?(cm2)-1]>2% oleic acid [(125.16±6.5) μg?(cm2)-1]>no enhancer [(109.82±8.2)μg?(cm2)-1].4% azone was the best penetration enhancer for the mucilage delivery in vitro, with Q and J value as [(222.75± 3.4)μg?( cm2 )-1 ] and 19. 896 μg?( cm2 )-1?h-1 , respectively, which was 2. 08 times those of mucilages without any enhancer. Conclusion Being as a transdermal absorption enhancer of Xiaoyan Runma mucilage, 4% azone has the best effect. This study can provide the optimal formulation for transdermal delivery system of Xiaoyan Runma mucilage.

Objective To investigate the effect and safety of early electric bronchoscope on patients with nonresponding pneumonia. Method Seventy non responding pneumonia patients were selected from our hospital , who received treatments from January 2015 to April 2016.According to the random table ,patients were randomly divided into the observation group(34 cases)and the control group(36 cases). According to the experience and sputum culture results,patients in the control group were given the conventional therapy,and patients in the observation group were given bronchoscope and transbronchil lung biopsy(TBLB). The effect of bronchoscopy,the treatment curative effect,duration of fever,the period of the elevated CRP dropped to baseline,the length of hospital stay and medical costs were compared between the two groups. Results The diagnostic rate of bronchoscopy and the positive rate of airway suction bacterial culture in the observation group were similar with those in the control group,with no significant differences. The positive rate of airway suction bacterial culture was significantly higher than that of sputum culture in the observation group. The positive rate of airway suction bacterial culture was higher than that of sputum culture in the control group ,but with no significant difference.The total effective rate in the observation group(87.1%)was significantly higher than that in the control group(58.8%). The duration of fever and the time of the elevated CRP dropped to baseline in the observation group were significantly shorter than those in the control group. The hospital stay and hospital costs in the observation group were also significantly lower than those in the control group. Conclusion Early bronchoscopy can obtain diagnosis evidence of etiology and histology and improve the diagnostic rate,meanwhile,it also has a therapeutic effect.It can improve the clinical treatment effect and shorten the healing time and the cost of hospitalization. In addition , early electronic bronchoscopy has fewer adverse reactions and it may play an important role in diagnosis and treatment on nonresponding pneumonia patients.

Objective Percutaneous puncture of gasserian ganglion was guided by CT scan to improve the accuracy and reduce complications and to compare the efficacy of chemical mutilation with ethyl alcohol and adriamycin.Methods Ninety-two patients with primary trigeminal neuralgia (39 males, 53 females) aged 37-84 yrs were divided into two groups : A ethyl alcohol group ( n = 47) and B adriamycin group ( n = 45) . Secondary trigeminal neuralgia was excluded by preoperative CT scan. Percutaneous puncture of oval foramen was guided by CT and correct location of needle tip was confirmed by injection of contrast medium. 100% ethyl alcohol 0.5ml (group A) or 2% adriamycin 0.5ml was injected.Results The patients were followed up for 12 months after treatment. Neuralgia disappeared in 31 out of 47 patients in group A (alcohol group) and in 36 out of 45 patients in group B (adriomycin group) . Treatment failed in 13 patients in group A and 6 patients in group B, and was partly effective in the other patients. There were no severe side effects or complications. Conclusion Percutaneous puncture of gasserian ganglion guided by CT is effective and reduces complications. Adriamycin is more effective than ethyl alcohol for chemical mutilation.
