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.

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. Methods 208 patients with chronic hepatitis C were included, and divided into two groups randomly, PEG IFN? 2a group and IFN? 2a Group respectively. 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 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.

BACKGROUND: Human placenta is a stable source for human amniotic epithelial cells, which is becoming a cellsource in the regenerative medicine that attracts widespread attentions.OBJECTIVE: To establish the method of isolation, culture, and adipogenic, chondric and osteogenic differentiationof human amniotic epithelial cells. METHODS: Trypsin-EDTA digestion was used to isolate human amniotic epithelial cells from human amnion tissue,which were then cultured and identified in vitro. The growth curve of the cells was observed in 12 days. Passage 1human amniotic epithelial cells were induced to differentiate into adipocytes, chondrocytes and osteoblasts, andconventional cultured cells were used as controls. After 16 days induction, oil red O, Masson and alkaline phosphatesstaining methods were carried out, and adipogenic transcription factor, type Ⅱ collagen, osteopontin, alkalinephosphatase mRNA expressions were detected using real-time fluorescene quantitative PCR.RESULTS AND CONCLUSION: Human amniotic epithelial cells were successfully obtained from human amnion tissue.Immunofluorescence data showed the expression of epithelial cell surface marker CK19. Passage 1 cells had a strongability to divide and proliferate. Compared with passage 1 ones, passage 2 cells showed a slight decrease in proliferationability, and the proliferation ability of passage 3 cells was the worst. Red lipid droplets, brilliant blue cartilage matrix andreddish brown calcium nodes were detected by oil red O, Masson and alkaline phosphates staining after adipogenic,chondrogenic and osteogenic differentiation, respectively. With the time prolonged, the expressions of adipogenictranscription factor, type Ⅱ collagen, osteopontin and alkaline phosphatase mRNA were increased. These resultsdemonstrated that human amniotic epithelial cells could be isolated from human amniotic membrane by enzymedigestion method, and these amniotic epithelial cells could be induced to differentiate into differentiate into adipocytes,chondrocytes and osteoblasts.

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.

There have emerged gradually serious one-sided benefits chasing behaviour over the past 10 years in many hospitals. In this article we've tried to analyze its scocial roots and disclose its harming effects which lead us to ethical misunderstanding and contradict serving tenets in our clinical practice. We also present these pertinent criteria of medical ethics and search after approaches for keeping away these mistakes repeatedly.

OBJECTIVE:To evaluate the curative efficacy of granulocyte macrophage colony stimulating factor (GM-CSF) as an adjunctive therapy for the treatment of acute myeloid leukemia (AML). METHODS: Randomized controlled trials (RCTs) of GM-CSF in the treatment of AML were retrieved from PubMed,EMBase,Cochrane Library,CBMdisc and CNKI database by computer as well as from the leukemia-related journals manually for a quality evaluation of the methodology and Meta analysis using RevMan5.0 software. RESULTS: A total of 10 RCTs were included,of which,3 RCTs were graded as A,5 as B and 2 as C. The results demonstrated that there were no significant differences of indexes among groups as complete remission (CR) rate,relapse rate,infection rate and length of hospital stay,etc. CONCLUSION: The available clinical research results showed that GM-CSF adjunctive therapy could neither increase CR rate,nor decrease the relapse rate,infection rate or length of hospital stay.
