This article,in view of the research status and development tendency of hospital core competence,introduced the index selection process and constructed the evaluation index system of core competence.This system comprises 3 level-1 indexes (social reputation,hospital health resources and development potential)and 9 level-2 indexes,with recommendations on improvements of the existing system.

In this paper,based on theoretical analysis,the concept of hospital core competence is redefined,combined with the needs of hospital's development in medical service market,the connotation is also clearly definition,and the characteri stics is summarized.Meanwhile,on the basis of all above,this paper has carried on a thorough discussion about the construction of Chinese hospital core competence.

A discussion of the connotation and key issues of the new normal in the healthcare sector,with an introduction to the new normal.The furthering reform is unveiling roadblocks in the healthcare system.For example,human resources available can hardly support development of the sector, and revenue growth of tertiary hospitals in the cities will decline,while county hospitals will be further challenged by debt crisis.In the meantime of steady elevation of medical capabilities in both urban and rural areas,the gap between the two will be maintained for a while.The authors predict that the sector will be faced with restructuring essential medicine system,grading diagnosis and treatment practice,rising risks for health insurance,and growing market shares of commercial health insurance and private capital, as well as fiercer competitions to challenge public hospitals.

With dwindling number of new antibiotics and inappropriate use of antibiotics, the emergence and spread of antibiotics resistance occurs commonly in healthcare institutions worldwide. In China, antibiotics are commonly overprescribed and misused. This study is to assess the effect of the nationwide special campaign on antibiotic stewardship program (ASP) at specialized hospitals in China by investigating prescription information from 2011 to 2012. Data on the hospital consumption and prescription of systemic antibiotics were obtained from four specialized hospitals, including maternity, children's, stomatological and cancer hospitals. Systematic random sampling was used to select outpatient prescriptions and inpatient cases. A total of 105 specialized hospitals in 2011 and 121 specialized hospitals in 2012 were analysed. The defined daily doses (DDDs) per 100 inpatient days, the percentage of antibiotic use in outpatient prescriptions, and the percentage of antibiotic use in inpatient cases were used as measurements of antibiotic use. The overall antibiotic use density in the selected hospitals decreased between 2011 and 2012 from 39.37 to 26.54 DDD/100 inpatient days (P<0.001). The percentage of antibiotic use in outpatient prescriptions (range: 24.12%-18.71%, P=0.109) and inpatient cases (64.85%-60.10%, P=0.006) also decreased within the two years. Significant changes were observed among regions and different hospitals within the two years. And antibiotic consumption was correlated with the type and size of specialized hospital in 2012, but not with the regions. This analysis of antibiotic consumption of specialized hospitals allows relevant comparisons for benchmarking and shows that national ASP has improved antibiotic rational use in China. The data will assist policymakers in formulating effective strategies to decrease antibiotic overuse and identify areas that require further work.

BACKGROUND:Autologous bone graft is the best method to repair bone defects after tumor curettage, but its shortcomings are as folows: increased surgical trauma, sequelae at bone graft site such as infection and pain, and a limited amount of autologous bone. OBJECTIVE:To analyze the effectiveness of xenograft and calcium sulphate artificial bone in treating bone defects after benign bone tumor removed. METHODS:Totaly 26 cases of benign bone tumor were selected, including 8 cases of giant celltumor, 5 of enchondroma, 4 of fibrous histiocytoma, 3 of bone fibrous dysplasia, 2 of non-ossifying fibroma, 2 cases of bone cysts, 1 of aneurysmal bone cyst and 1 of aneurysmal bone cyst and 1 case of chondroblastoma. Of the 26 cases, 12 cases underwent calcium sulphate pelets alone to fil bone defects after benign bone tumor removed, 6 cases were subjected to xenograft alone, and 8 cases were treated with calcium sulphate pelets combined with xenograft. The X-rays were taken at 1 week, 3 months, and 1 year after the operation in al patients to assess the bone healing process. RESULTS AND CONCLUSION:Al the patients were folowed up for 36-72 months. The absorption of calcium sulphate appeared to be absorbed earlier, the earlier absorption appearance could be observed as earlier as 1 month after the implantation, and most calcium sulphate was absolved and replaced by new bone at 3 months after the operation. The xenograft bone was degraded at 3 months post implantation and new bone formed. Osseo integration of the graft was observed at the periphery of the implant at 6 months post implantation. One year post implantation, trabecular bone was observed at the site with uniform bone density. In the combined group, thecalcium sulphate pelets were absorbed earlier and new bone formed earlier than the calcium sulphate alone group, and the xenograft absorbed later than the calcium sulphate pelets. Generaly, bony union was detectable 1 year after operation. These findings indicate that xenograft and calcium sulphate in treating benign bone tumor have acquired good results, which can be used as a substitute of autologous bone.

Objective To evaluate the relationship between genetic polymorphism of transforming growth factor (TGF)-β1 and susceptibility of liver cirrhosis after hepatitis B virus infection in Chinese population. Methods CBM, VIP, CNKI, Wanfang technological periodical full-text databases and Pubmed from set up to July, 2013 were electronically searched to identify case-control studies on the relationship between genetic polymorphism of TGF-β1 promoter 509 site, co-don 869 site and liver cirrhosis after hepatitis B virus infection. The data were quantitatively analyzed by RevMan 5.1 soft-ware after assessing the quality of included studies. Results Six case-control studies were selected for Meta-analysis based on our inclusion and exclusion standards. The results of Meta-analysis showed that the pooled OR value for liver cir-rhosis among Chinese patients after hepatitis B virus infection with T allele of TGF-β1 gene at promoter 509 was 1.02 (95%CI:0.67-1.54), the pooled OR values for patients with TT and CT genotypes were 0.80 (95%CI:0.36-1.78). OR values for pa-tients with C allele of TGF-β1 gene at codon 869 was 1.05 (95%CI:0.69-1.62), the pooled OR values for patients with CC and CT genotypes were 0.98 (95%CI:0.48-2.00). No significant publication bias was found. Conclusion The genetic poly-morphism of TGF-β1 at promoter 509 and codon 869 showed no association with susceptibility of liver cirrhosis after hepati-tis B virus infection in Chinese population.

Objective:To evaluate the accuracy and feasibility of sentinel lymph node biopsy (SLNB) marked by 99Tcm-IT-Ritux-imab and to discuss the clinical value of the method in diagnosis and treatment of cutaneous melanoma. Methods:A total of 67 patients with cutaneous malignant melanoma received 99Tcm-IT-Rituximab-tagged SLNB from March 2008 to March 2012. Lymphoscintigra-phy was conducted 30 min to 1 h after intra-dermal injection of 99Tcm-IT-Rituximab. Subsequently, the surgery of SLNB was carried out using gamma probe. The detection and positive rates of SLNB were counted. The relationship between the status and the clinical features of the sentinel lymph node (SLN) was analyzed, such as the T stage, ulceration, age, gender, and location. The influence of SLN status on overall survival (OS) and disease-free survival (DFS) was evaluated. Results:SLNs were detected in all the 67 patients by SPECT and gamma detector, with detection rate of 100%. Fifteen patients had SLN metastasis, and the positive rate was 22.4%. Chi-square indicates that SLN metastasis is associated with age, T stage, and ulceration (P<0.05). A total of 63 patients were followed up for 24-69 months, and the median follow up time was 43 months. Kaplan-Meier survival analysis shows that both OS and DFS in the SLN-negative group are better than those in the SLN-positive group (OS:93.9%vs. 57.1%, P<0.01;DFS:79.6%versus 28.6%, P<0.01). Cox-regression multiple factors analysis suggests that both SLN status and T stage are independent factors that affect the DFS of malignant melanoma. Conclusion:SLNB assisted by 99Tcm-IT-Rituximab can well reflect the state of lymph node metastasis and is es-sential for accurate staging, prognosis judging, and treatment guiding. Its operation procedure is simple with high accuracy, and the im-aging status is stable. Therefore, it is convenient and feasible as a means of SLNB.
