Based on literature review determining evaluation dimensionality,and with the relevant policies,the original index system is determined.Through using two rounds of focus group discussion and two rounds of expert consultation method,a set of county hospitals comprehensive reform of index system,which consists of 3 primary,14 secondary indicators and 64 tertiary indexes,is established.The analytic hierarchy process is used to determine the weight of evaluation index.At the same time,the reliability and validity of index system are tested.This proves that the established evaluation index system can give scientific and reasonable assessment results for comprehensive reform of county-level hospitals.

Objective To evaluate the role of thoracoscopy-assisted mini-incision in surgical treatment of lung tuberculosis.Methods From 1999 to 2004,pulmonary lobectomy was performed with thoracoscopy-assisted mini-incision(5-7 cm) on 42 patients with lung tuberculosis(right superior lobectomy in 16,right middle lobectomy in 4,right inferior lobectomy in 4,left superior lobectomy in 10,left lingular lobectomy in 4,and left inferior lobectomy in 4).Results None of the patients were converted to open surgery.The mean operation time was 105 min(35-170 min);blood loss ranged 100-800 ml(mean,150 ml).In the patients,thoracic drainage lasted for 1-5 d(mean,2.8 d) after the operation,and the hospital stay was 4-11 d(mean,6.7 d).During a 2-to 13-month follow-up(mean,8.2),no patient showed positive sputum,bronchopleural fistula,or diffusion of tuberculosis.Conclusions Since thoracoscopy-assisted mini-incision is assosiated with minimal tissue injury,few blood loss,quick postoperative recovery,short hospital stay,and few complications after the surgical treatment of lung tuberculosis,it is worth being widely used.For surgeons,it is important to remember the indications for the procedure.

Objective To investigate the effect of different concentrations of dexmedetomidine on the apoptosis of hippocampal neurons in neonatal rat induced by propofol in vitro. Methods Hippocampal neurons of primary cultured neonatal SD rat were divided randomly into three groups. Group C (control group)was normal cultured without any treatment for 12 h; group P (Propofol group)was incubated with 12 μg/mL propofol for 12 h and group DP (Dexmedetomidine + propofol group)was incubated with 0.002 5 ~ 25 μg/mL dexmedetomidine for 30 min, and then further incubated with 12 μg/mL propofol for 12 h. Results Compared with that of group C, the apoptosis rate of hippocampal neurons increased in group P and DP (P < 0.05 or P < 0.01); Compared with that of group P, the apoptosis rate of neurons decreased with the increase of dexmedetomidine concentration in group DP (P<0.05 or P<0.01). The result of transmission electron microscope indicated that compared with group C , group P showed obvious neuronal damage; the nerve cells damage alleviated in group DP, which were negatively associated with the concentration. Conclusions With the concentration ranging from 0.002 5 to 25 μg/mL, dexmedetomidine set pre-incubation and breeding can reduce apoptosis of hippocampus neuron of neonatal rats induced by propofol and the effect is concentration dependent.

Objective:Study on characteristics of two synthesizd peptides based on CSFV E2 protein. Methods:B cell epitopes of CSFV E2 antigen were predicted using accessibility and flexibility schemes, associated with antigenicity , secondary structure and multiple sites prediction. Two antigen peptides (Pep1 and Pep2) have been designed and synthesized and their reactivety were detected with 8 McAbs and antiserum against mE2 protein, then the peptides were conjugated with BSA and immunized rabbits respectively. Results:Both Pep1 and Pep2 could react with antiserum and McAb A11, Pep2 could interact with McAbD5 and McAbD8. Only Pep1 BSA conjugate can stimulate high level and specific antibodies.Conclusion: The peptide1 has good antigenicity.

Objective To study the expression and regulation of pro‐inflammatory cytokinesTNF‐α,IL‐1 ,IL‐6 in mononucle‐ar macrophages stimulated with staphylococcal protein A (SpA) .Methods THP‐1 was incubated with PMA and induced into mononuclear macrophages .Then the macrophages were incubated with varying concentrations of SpA under different time points . The effect of SpA on macrophage proliferation was measured by MTT method .The levels of inflammatory cytokines ,TNF‐α,IL‐1 and IL‐6 from the cultured cell media were measured by ELISA respectively .The levels of mRNA expression corresponding to TNF‐α,IL‐1 and IL‐6 were detected by RT‐PCR from the macrophages stimulated with SpA .All statistical analyses were performed by SPSS17 .0 software .Results The MTT result indicated that SpA had a positive effect on the proliferation of THP‐1 cells in a dosage depended manner .The addition of SpA could enhance the mRNA expression of TNF‐α,IL‐1 and IL‐6 in the stimulated mac‐rophages .It also showed a specific dose‐effect and time‐effect correlation .The macrophages secreted inflammatory cytokines and its corresponding mRNA reached its peak levels at 12 h post stimulation .Compared with the control group ,the expression and release of TNF‐α,IL‐1 and IL‐6 in macrophages from the experimental group was increased with statistical significance(P<0 .01) .Conclu‐sion SpA can promote the secretion and expression of early pro‐inflammatory cytokines ,such as TNF‐α,IL‐1 and IL‐6 in macro‐phages .Therefore ,SpA plays a very important role in the initiation and development of the staphylococcus aureus sepsis .

Objective:To study the effects of compatibility circumstances on guizhi's effect in dispelling cold and relieving exterior in complex prescriptions. Methods:202 formulae that effected on Sanhanjiebiao were collected from 1425 formulae with guizhi,and the frequency of herbs combining with guizhi in 202 formulae was ranked from high to low.

The quality of a donor liver after cardiac death is closely associated with energy metabolism during preservation. Ex vivo mechanical perfusion has broad application prospects because this technique can help energy metabolism and repair ischemia injury of donors' livers. Some core issues are presented in this review in order to provide references for propelling secure application of liver transplantation based on donation after cardiac death.

Objective:To study the effect of mesalazine hydroxyl-propyl-β-cyclodextrin inclusion compound ( MSZ-HP-β-CD) liq-uid suppositories on ulcerative colitis ( UC) in rats. Methods:Dextran sulfate sodium was used to induce UC in rats. The marketed MSZ suppositories were applied as the positive control, and the changes in morphology and histopathology of the UC rats were observed after the treatment with MSZ-HP-β-CD liquid suppositories. Results:The results of morphology study showed that CMDI was decreased in the two MSZ preparation groups when compared with that in the model group (P<0. 01), and that in MSZ-HP-β-CD liquid supposi-tories group was the lowest (P<0. 05). The results of histopathology study showed that with the treatment of the marketed MSZ sup-positories and MSZ-HP-β-CD liquid suppositories, the ulcer and damage were improved, and the improvement in the MSZ-HP-β-CD liquid suppositories group was more significant. Conclusion: MSZ-HP-β-CD liquid suppositories exhibit better effect on UC in rats when compared with the marketed MSZ suppositories, which is worthy of further studies.

We developed a universal probe based microRNA detection assay and applied it to detect microRNA-146a in human brucellosis,testing the possibility of using it as diagnosis signature.By using orthogonal design,the annealing temperature,probe concentration and commercial kits were optimized and the assay was developed.Total RNAs were isolated from plasma of human brucellosis and healthy control,and microRNA-146a was detected and compared.Results reveal that the optimized universal probe assay was established,which was more specific than the SYBR GreenI assay,and had a wider range of amplification.Compared with healthy control,the application of universal probe assay for the detection of serum microRNA146a in patients with brucellosis was significantly inhibited (P＜0.01).Implying the potential of microRNA-146a as biomarker in diagnosis of brucellosis.It is suggested that universal probe based assay is a universal,specific and sensitive method for microRNA detection.MicroRNA-146a represents a potential biomarker for human brucellosis diagnosis.
