Objective To analyze the key factors influencing the number of diseases or conditions in which clinical pathways ( CPs) were implemented at public hospitals of China. Methods Based on the questionnaire survey of 51 public hospitals that had implemented CPs in Shanghai, Hubei province, and Gansu province, a multivariate logistic model was used to analyze the factors that influenced the number of CPs implemented in hospitals. Results In terms of the 14 issues and difficulties found in CPs′implementation, the overall acceptance rate was 38. 8% on average among surveyed hospitals, yet with a great variation(from 7. 1% to 100. 0%). A multivariate logistic model showed that the recognition of public hospitals on the issues and difficulties in CPs′implementation did not affect the number of implemented CPs, and tertiary public hospitals had significantly higher number of CPs implemented than secondary hospitals. Conclusions The resources and management capabilities of public hospitals in China are the determinants of CPs′promotion.

Objective To analyze the management of clinical pathways ( CP) in China. Methods Cross-sectional questionnaire surveys of 51 public hospitals with CPs in place in Shanghai, Hubei province and Gansu province were conducted from March to May of 2015. Results Among the 51 public hospitals with CPs, 48 ( 94. 1%) of them organized training on CPs, 48 ( 94. 1%) of them monitored CPs′implementation, and 40 (78. 4%) applied incentives for CPs′ implementation. But there were some issues and difficulties encountered in CPs′ implementation. Conclusions Comprehensive measures are necessary to improve the management of CPs at public hospitals of China.

Objective To analyze the implementation of clinical pathways ( CP) at public hospitals at different levels and in different regions in China. Methods The status of CPs′ implementation at 54 public hospitals in Shanghai, Hubei province and Gansu province was surveyed by questionnaires from March to May of 2015. Results 51 (94. 4%) of the surveyed public hospitals put in place clinical pathway(s), where the average CPs implemented were 45 and the average percentage of the cases using CPs was 52. 7%. There were great variations among these hospitals. In addition, the common diseases with definite diagnostic and treatment options were found with the highest implementation rates of CPs at such hospitals. Conclusions CPs are implemented widely at public hospitals of China, yet enhanced implementation strategies are expected to further CPs′adoption.

Objective To sequence and analyze the envelope (E) gene of type Ⅰ dengue virus isolated from Guangzhou in 2009 for tracing the infection source. Methods The serum samples were collected from patients diagnosed with dengue fever in Guangzhou area during 2009. Dengue virus was isolated and cultured in C6/36 cells.The whole length of E gene was amplified by reverse transcriptase-polymerase chain reaction (RT-PCR) and then sequenced. The phylogenetic tree was drawn by neighbor-joining method. The bioinformatics analysis was performed by combining the phylogenetic information and the epidemiology data. Results Four strains of type Ⅰ dengue virus were isolated from 19 samples. E gene of these strains was amplified and sequenced. The phylogenetic analysis showed that 09/GZ/9104 strain and 09/GZ/9236 strain had identical nucleotide sequence and fell within the American/African group, 09/GZ/11534 stain and 09/GZ/11562 strain had similar sequence homology and fell within the Asian group. Conclusion The typeⅠdengue viruses in Guangzhou area in 2009 are imported, which belong to two genotypes and may come from two independent origins respectively.

In this study ,we established Cross Priming Amplification (CPA ) technology for detection of influenza A virus (H1N1) approach ,and evaluated the method through clinical specimens .A set of specific primers were designed for CPA ac‐cording to the conservative gene sequences ,designed and realized in the same temperature reverse transcription of RNA and DNA amplification . The amplification products can be totally enclosed nucleic acid detection device for testing . Fourteen healthy pharyngeal swab specimens ,seven other respiratory viruses ,and six arboviruses strains were used as the controls .We used a method that application of gradient dilution to the H 1N1 virus strain as the control to test the sensitivity of the CPA .We also used 102 clinical pharyngeal swab specimens of H1N1 patients for detection object to evaluate the feasibility of CPA clinical detection .Results showed that the CPA reaction did not appear cross reaction on health cases samples and other viruses .The sensitivity of the CPA was approximately 10 copies/uL in the established method that exactly titer H1N1 virus strain gradient dilution test .As to the positive results among the clinical pharyngeal swab samples collected from patients at different stages after onset ,the CPA had the highest positive detection rate during the first three days after onset (100% ) .While the detection rate from day 4 to day 6 after onset was 79 .31% .After 7 days ,the detection rate was 9 .09% .The established CPA assay was a highly sensitive ,specific and reproducible approach for rapid detection of H1N1 virus ,which is conducive to the early diagno‐sis of influenza A virus (H1N1) for basic medical units .

OBJECTIVETo investigate the clinical and pathological features and prognostic factors of primary intestinal non-Hodgkin's lymphoma (NHL).

METHODSThirty-Two cases of intestinal NHL were studied clinically and pathologically. All cases were reclassified according to the WHO classification of lymphoma in 2001.

RESULTSTwenty-one cases (65.6%) were diagnosed as B-cell lymphomas, including 15 cases of diffuse large B-cell lymphoma, 2 cases of mantle cell lymphoma, 1 case of follicular lymphoma, 2 cases of MALT lymphoma and 1 case of Burkitt's lymphoma. Ten cases (31.2%) were diagnosed as T cell lymphomas, including 2 enteropathy-associated T cell lymphomas (EATCL) and 8 cases non-EATCL. One case (3.1%) was diagnosed as histiocytic lymphoma. Nine cases were at stage I-II and 23 cases were at stage III-IV. Follow-up information was available in all cases ranging from 4 to 168 months (mean 25.6 months). Fifteen cases died of the disease. The mortality rates were 33% for B cell lymphoma and 80% for T cell neoplasms. Based on Cox multivariate analysis, the clinical stage and histological types of the disease were important prognostic factors (P < 0.05). T cell lymphoma had a relatively poor prognosis.

CONCLUSIONSDiffuse large B cell lymphoma is the most common subtype of primary intestinal lymphomas. Colon is the most common site involved, followed by the small intestine. Early stage of the disease and low-grade lymphoma appear to have a better prognosis. T cell lymphoma has a very poor prognosis.

Objective The purpose of this study was to approach the relation of SNP43,SNP44 locus, main haplotypes and haplotype combinations with type 2 diabetes mellitus(T2DM).Methods According to the theory and principles of systematic review,data from case-control studies regarding the association between calpain-10(CAPN10) gene and T2DM were derived through electronic search of PubMed and Chinese journals databases.To gain a more precise estimation of the relationship,a stratified Meta-analysis with four subgroups was pertbrmed according to the races.Publication bias Was also assessed.Results The association with T2DM in different races was evaluated.In Mongoloid race,SNP43-G allele,G/G genotype and 111/221 haplotype combination showed notable association with T2DM with Ors (95%CI) as 1.368(1.155-1.620),1.437(1.186-1.741) and 2.762 (1.287-5.927) respectively.In Caucasoid race,SNP44-C allele,111/111 hapotype combination showed strong relationship with T2DM with Ors(95%CI) as 1.144(1.023-1.278),1.291(1.050-1.586) respectively.In Hybrid race,only one positive finding Was obtained which Was SNP44-C allele with OR(95%CI)as 1.653(1.025-2.665).Conclusion SNP43-G allele,G/G genotype,111/221 were risk factors to Mongoloid race.And SNP-C allele,111/111 haplotype combination were risk factors to Caucasoid race,and SNP44-C allele to Hybrid race.
