Objective: To explore health resource allocation and optimization and evaluate the clinical departments efficiency in hospital. Methods: Taking a three level of first-class hospital in Beijing for example, the method of data envelopment analysis (DEA) was used for building a DEA model of clinical departments efficiency in hospital. Results: Based on the results of the DEA model, we drawn the technical efficiency and scale efficiency of the target clinical departments, obtained input redundancy rates and output deficiency rates of the non-effective decision-making units. Conclusion:By DEA evaluation results, the input redundancy and output deficiency of the target clinical departments are found. From the perspective of optimizing hospital resource allocation, measures to improve the hospital operational performance are proposed. There is important significance to improve the comprehensive competitiveness of the hospital.

Neck shoulder pain or lumbocrural pain caused by intervertebral disc degeneration (IDD) could seriously affect the qualities life of patients. Current treatments mainly focus on alleviating pain and the symptoms of nerve compression, which could not radically stop the process of intervertebral disc degeneration, but conversely lead to high recurrence rate. In recent years, scholars have turned to study the biological treatment for repair and rebuild the intervertebral disc by biological molecular therapy, gene therapy, cell therapy and tissue engineering to solve the problem of intervertebral disc degeneration, while most of the above methods are still in animal experiments or in vitro experiments and the clinical application is still a long way to go.

Objective:This study aimed to assess the efficacy of comprehensive laparoscopic surgical staging in early-stage ovari-an cancer, and provide references for clinical practice and research. Methods: Electronic databases, such as Embase, Medline, Co-chrane Library, CBM, and CNKI, were searched for studies on comprehensive laparoscopic surgical staging versus comprehensive lapa-rotomic surgical staging. Other sources, such as related references, were also retrieved. The literature was screened according to inclu-sion criteria. Data were extracted from the selected references, and the quality of the included studies was assessed. This meta-analysis was performed using RevMan 5.2 software. Results:A total of 11 studies involving 591 cases were selected, of which 235 cases be-longed to the laparoscopy group and 356 belonged to the laparotomy group. No statistically significant differences were observed be-tween groups in age, body mass index, clinical stage, histological type, and histological grade. The laparoscopy group had less intraoper-ative blood loss, earlier general diet intake, less postoperative complications, and lower postoperative recurrence rate than the laparoto-my group. No statistically significant difference was observed between groups in operation time, pelvic lymph node number (apart from pelvic and para-aortic lymph nodes), mortality. Conclusion:The results of this systematic review show that laparoscopic surgical stag-ing of early-stage ovarian cancer demonstrated staging adequacy and accuracy that were similar to those of laparotomic surgical stag-ing. Based on the principle of minimal invasion and radical treatment to tumor, laparoscopy showed more favorable operative outcomes than laparotomy.

OBJECTIVETo detect the expression level of interleukin 17 (IL-17) in the plasma and colonic mucosa of patients with ulcerative colitis (UC), and to explore the synergistic mechanism of qingchang huashi recipe (QHR) combined with Mesalazine.

METHODSRecruited were 24 mild or moderate UC patients of damp-heat inner accumulation syndrome (DHIAS). Their samples of intestinal tissues were histologically graded. They were assigned to the combination group and the Western medicine (WM) group, 12 in each group. Besides, another 12 healthy volunteers were recruited as the healthy control group. QHR combined Mesalazine were given to patients in the combination group, while those in the WM group took Mesalazine. The therapeutic course for all was 3 months. By the end of treatment the expression level of IL-17 in the plasma and colonic mucosa was detected using ELISA. The infiltration of IL-17 in the intestinal mucosal tissue was detected by immunohistochemical SP method.

RESULTSThe expression level of IL-17 in the plasma and colonic mucosa was significantly higher in UC patients than in healthy controls (P <0. 05). The higher the histological grading the higher the expression level. The expression level of IL-17 in plasma and colonic tissues decreased after treatment in the two treatment groups (P < 0.05). Besides, the expression level of IL-17 was lower in the combination group than in the WM group (P <0.05).

CONCLUSIONQHR combined Mesalazine could synergically enhance the effect and effectively inhibit intestinal inflammation through down-regulating the expression of IL-17.

BACKGROUND:Preliminary studies have showed that vacuum sealing drainage based on wound surface dressing biomaterials is a good method to cover the wound as succedaneous peau when the soft tissuedefects along with open fracture cannot be completely repaired during the first operation. OBJECTIVE:To explore the efficacy of vacuum sealing drainage based on wound surface dressing biomaterials in repair of soft tissue defects of foot and ankle. METHODS:Fourteen patients with soft tissue defects of foot and ankle were treated using free skin graft combined with vacuum sealing drainage technique. Meanwhile, the traditional skin graft after wound dressing changes was applied in another 11 patients. The clinical outcomes were compared between two groups. RESULTS AND CONCLUSION:The transplanted skin in 10 cases of the vacuum sealing drainage group survived. The total survival rate was 71%, and surgical dressing change was applied in the left four patients to finaly cover the wound. By comparison, the transplanted skin in four cases of the traditional group survived. The total survival rate was 54%. To finish the wound, three of the left patients were turned to surgical dressing change and two of them stil needed skin graft operation once more. The total survival rate between the two groups has no statistical significance(P > 0.05). The therapeutic procedure noted that the time waiting for the secondary surgical visit, times for dressing change before the second intervention and the time for final union between the two groups were statisticaly different (P < 0.05). So the vacuum sealing drainage based on wound surface dressing biomaterials may accelerate the repair of soft tissue defects of foot and ankle when using the free skin graft operation.

Objective To investigate the genotypes of aminoglycoside-modifying enzymes (AMEs) produced by Pseudomonas aeruginosa isolated from Huaibei Miner's General Hospital.Methods Minimum inhibitory concentration of 36 strains of P. aeruginosa to 3 aminoglycoside antibiotics was determined. AME genes were amplified by polymerase chain reaction (PCR). Results The P. aeruginosa isolates were resistant to multiple antibiotics. Most (62.2% to 81.1%) were resistant to aminoglycosides. And 27 strain (75.0%) carried one or more types of AME genes, including ant(3″)-Ⅰ (63.9%), aac(6')-Ⅱ (58.3%), aac(6')-Ⅰ (50.0%), aac(3)-Ⅱ (38.9%) and ant(2″)-Ⅰ (36.1%). The aac(3)-Ⅰ, aac(3)-Ⅲ, aac(3)-Ⅳ, aph(3')-Ⅳ genes were not identified.Conclusions The study indicates that the P. aeruginosa isolates in Huaibei are multi-resistant to aminoglycoside antibiotics. The prevalence of AMEs-positive strains is high.

Objective To investigate the efficacy, tolerability and safety profiles of PEG IFN alpha 2a(PEG IFN? 2a) in the treatment of chronic hepatitis C in China.

There was no significant difference between two groups in pretreatment HCV RNA, HCV genotype and other clinical data. The main parameters to valuate the efficacy were virological response and biochemical response. The side effects were intensively observed. Results Sustained virological response rate in PEG IFN? 2a group was significantly higher than that in IFN? 2a group (41.51% and 16.67% respectively, P

Objective To investigate the clinical effects and complications of uterine artery embolization (UAE) therapy using different embolic agents in treating uterine adenomyosis. Methods During 2004—2011, a total of 45 female patients with uterine adenomyosis were admmitted to authors’ hospital to receive uterine artery embolization therapy. The embolic agents used in the procedures included domestic iodized oil, sodium alginate microspheres and Embosphere microspheres. The patients were randomly divided into group A (n=15, using domestic iodized oil as embolic agent), Group B (n=13, using sodium alginate microspheres as embolic agent) and group C (n = 17, using Embosphere microspheres as embolic agent). After the treatment, all the patients were followed up for over 2 years, focusing on the observation of the clinical symptoms such dysmenorrheal, changes of MRI signs and severe complications. The results were analyzed and compared among the three groups. Results After UAE, the clinical symptoms such as the degree of dysmenorrhea, menstrual quantity, etc. were improved in all patients. Six months after UAE, the obvious remission rate of dysmenorrheal in group A, B and C was 33.3% (5/15), 30.8% (4/13) and 41.1%(7/17) respectively. Twelve months after UAE, MRI scanning showed that the uterine sizes in group A, B and C were reduced to 49.19%, 48.25% and 50.05% respectively. Follow-up examination at 24 months after UAE showed that recurrence of dysmenorrheal in group A, B and C was seen in 2, 4 and 2 cases respectively, and amenorrhea was seen in 2 cases of group A and one case in group C. Conclusion The use of domestic iodized oil, sodium alginate microspheres or Embosphere microspheres as embolic agents in performing super-selective uterine artery embolization for adenomyosis can effectively relieve the degree of dysmenorrheal, decrease the uterine size. In addition to ovarian dysfunction, the uterine cavity adhesion may be also a possible cause of amenorrhea occurring after UAE may. In order to ensure a similar clinical efficacy, the use of granular solid embolic agent is preferred as its safety is possibly higher than the liquid embolic agents.

AIM: To obtain differentially expressed cDNA fragments in the cerebellum of rats and screen unknown expressed sequence tag (EST). METHODS: Suppression subtractive hybridization (SSH) was carried out, in which the cDNA fragments of cerebellum were taken as "tester" and correspondingly that of cerebrum and brain stem as "driver". The homogeneous sequences between the tester and driver were excluded and the rare sequences in cerebellum were enriched by SSH. The differentially expressed cDNA fragments were further cloned for the construction of subtracted cDNA libraries and sequencing. RESULTS: 32 clones were selected and 34 cDNA fragments were sequenced. 8 of 32 were proved to be true positive with reverse Northern assay, 13 of 34 fragments were identified to be new cDNA fragment and given the gene sequence numbers by GenBank (AW288461-AW288474). CONCLUSION: SSH is very useful method for screening differentially expressed genes. Our data may be helpful to understand the molecular mechanism of brain function.
