Objective To study the correlation between human leukocyte antigen (HLA)-DRB1 alleles and anti neutrophil cytoplasmatic antibodies (ANCA) in Han and Uygur ulcerative colitis (UC)patients in Xinjiang region.Methods The serum ANCA was determined by indirect immunofluorescence assay in 62 Uygur UC patients,58 Han UC patients,188 Uygur and 184 Han healthy control individuals.HLA-DRB1 typing was performed by polymerase chain reaction-sequence based typing (PCR-SBT).The allele frequency of HLA-DRB1 was compared in ANCA positive and negative Han and Uygur patients as well as healthy controls.Stratified analysis was performed according to UC clinical type,severity and involvement.SPSS 17.0 software was applied for x2 test.Once P＜0.05,the odds ratio (OR) and 95％ confidence intervals (95％CI) was calculated.Results The positive rate of ANCA in Uygur UC patients (53.2％,33/62) was significantly higher than that of Han patients (34.5％,20/58) and the difference was statistically significant (x2=4.269,P =0.045).In Uygur,the gene frequency of HLA-DRB1 * 13 in ANCA positive UC patients (0.202)was significantly higher than that of ANCA negative patients (0.017) (x2 =10.092,P=0.016,OR=16.000,95％CI:2.892 to 88.524) and healthy controls (0.075) (x2=9.351,P＝0.040,OR=3.407,95％CI:1.666 to 6.971).The gene frequency of HLA-DRB1 * 13 in ANCA positive pancolitis type UC patients (9/15) was significantly higher than that of ANCA negative pancolitis type UC patients (1/14) and the difference was statistically significant (x2=8.955,P =0.040,OR =19.500,95％CI:2.787 to 136.461).However,in Han patients,there were no significant differences of HLA-DRB1 alleles frequencies among ANCA positive patients,ANCA negative patients and healthy controls (all P＞0.05),and the results of stratified analysis were same.Conclusions In Uygur UC patients of Xinjiang region,HLA-DRB1 * 13 may correlated with ANCA and with ANCA of pancolitis type UC patients.There is no such correlation in Han patients of Xinjiang region.

ObjectiveTo investigate the correlation between benign prostate hyperplasia (BPH) and atherosclerosis (AS).Methods 95 cases were divided into two groups based on prostate volume (PV):24 cases with non-BPH (PV≤20 ml) and 71 cases with BPH (PV＞20 ml).Carotid intinal medial thickness (IMT) was determined by high resolution color Doppler sonography.ResultsLevels of triglyeeride (TG),hypersensitive C reactive protein (hs-CRP),ln fasting insulin [ln (FINS)],ln insulin resistance index [ln (HO)MA-IR)] and IMT in BPH group were significantly higher than in non-BPHgroup.The morbidity rate of coronary heart disease and cerebral arteriosclerosis in the BPH group enhanced as compared with non-BPH group.PV were positively correlated with ln(FINS),ln(HOMA-IR),TG and high density lipoprotein (HDL-C).Conclusions BPH is closely correlated with AS and their co-pathogenesis might be insulin resistance,inflammatory reaction and endothelial dysfunction.

Objective To investigate the relation of peripheral leukocyte total and its differential counts with urinary albumin(UAlb)in patients with type 2 diabetes.Methods The 564 subjects with type 2 diabetes were stratified according to UAER levels.The total and differential leukocyte counts of peripheral blood were measured.Demographic and potential metabolic confounding factors were analyzed with multiple correlation and logistic regressions to evaluate the effects of leukocyte counts on UAER.Results With the increase of UAER,the peripheral total leukocyte,neutrophil,monocyte,eosinophil and basophil counts increased.In contrast,the lymphocyte count decreased.The differences persisted even after adjusting the influence of age,sex,duration of diabetes and other known risk factors.Conclusions Our study shows that peripheral leukocyte counts,even within the normal range,are related with UAlb in subjects with type 2 diabetes in a dose-dependent manner.

Objective To compare the levels of serum high sensitivity C-reactive protein(hsC-RP) among subjects with normal fasting glucose plus normal glucose tolerance(NFG/NGT),IFG,IGT and IFG plus IGT,and to analyze the related risk factors. Methods 443 nondiabetic subjects aged 39-65 years were seperated into four groups:NFG plus NGT,IFG,IGT and IFG plus IGT.The serum hsC-RP levels and related factors were analyzed. Results Compared with IFG subjects,IGT subjects had higher hsC-RP levels.No differences in hsC-RP levels were found between NFG plus NGT group and IFG group, as well as between IGT group and IFG plus IGT group.Stepwise multiple regression showed that BMI and HOMA-IR were independent predictors of hsC-RP. Conclusions IGT subjects have significantly higher serum hsC-RP level than IFG subjetcts. The serum level of hsC-RP is associated with insulin resistance and the components numbers of metabolic syndrome.

Objective To investigate the influences of Radix salvia miltiorrhiza (RSM) preconditioning on the expressions of phosphorylated eukaryotic initiation factor 2α (p-eIF-2ot) and caspase12 in hepatic ischemia reperfusion in rats.Methods Eighty Wistar rats were randomly divided into the control group (5 rats),sham operation group (25 rats),ischemia reperfusion (IR) group (25 rats) and RSM pretreated group (25 rats).Rats in the sham operation group,IR group and RSM pretreated group were subdivided into 5 groups at different time intervals (0,3,12,24 and 72 hours).Mter midline laparotomy,all structures in the hepatic portal were clamped for 45 minutes followed by different periods of reperfusion.Rats in the control group did not receive any treatment; rats in the sham operation group only received anatomy of the hepatic portal without clamping; rats in the RSM pretreated group received RSM by intravenous injection 30 minutes before ischemia at a dose of 6 ml/kg.Rats in the sham operation group and the IR group received a dose of normal saline as RSM pretreated group.The protein expressions of p-eIF-2α and caspase12 in the hepatic tissues of each group were detected by the Western blot,and the pathological changes of hepatic tissues in each group were detected by hematoxylin and eosin staining.All data were analyzed using the analysis of variance,LSD test or Games-Howell method.Results The relative expression of p-eIF-2α in the control group was 0.296 ± 0.038,and the relative expressions of p-eIF-2α in the sham operation group at different time points were 0.304 ± 0.048,0.298 ± 0.038,0.272 ± 0.042,0.266 ± 0.076 and 0.296 ± 0.043,with no significant difference between the 2 groups (P ＞ 0.05).The relative expression of p-eIF-2α in the IR group at 0 hour was 0.310 ± 0.034,which had no significant difference compared with the control group and the sham operation group (F =0.15,P ＞0.05).The relative expressions of p-eIF-2α in the IR group at 3,12,24 hours were 0.386 ± 0.021,0.710 ± 0.034,0.474 ± 0.017,which had no significant difference compared with the control group and the sham operation group (F =11.90,211.52,25.15,P ＜ 0.05).The relative expression of p-eIF-2α in the IR group at 72 hours was 0.336 ± 0.043,which was back to the level of the control group and the sham operation group (F =1.57,P ＞ 0.05).The relative expressions of p-eIF-2α in the RSM pretreated group at different time intervals were 0.278 ± 0.044,0.800 ± 0.079,1.056 ± 0.125,0.736 ±0.087 and 0.442 ± 0.047,which were significantly lower than the group at 3,12,24,72 hours (P ＜ 0.05).The relative expression of caspase12 in the control group was 0.983 ± 0.003,and the relative expressions of caspase12 in the sham operation group at different time intervals were 0.974 ± 0.004,0.983 ± 0.005,0.985 ± 0.003,0.981 ± 0.004 and 0.978 ± 0.004,with no significant difference between the 2 groups (P ＞ 0.05).The relative expression of caspase12 in the IR group at 0 hour was increased to 1.018 ± 0.076,while it had no significant difference compared with the control group and the sham operation group (F =1.43,P ＞ 0.05).The relative expressions of caspase12 in the IR group began to rise at 3 hours (2.056 ±0.067),and peaked at the 12 hours (2.804 ± 0.050),still at a relative higher level at 24 hours (1.882 ± 0.037),and began to decrease at 72 hours (1.282 ± 0.066),it had significant difference compared with the control group and the sham operation group (F=1290.69,6490.84,2898.71,103.61,P ＜ 0.05).The relative expressions of caspase12 in the RSM pretreated group at different time intervals were 0.998 ± 0.056,1.442 ± 0.066,1.990 ± 0.068,1.364 ± 0.056and 0.962 ±0.054.The relative expressions of caspase12 in the RSM pretreated group at 3,12,24,72 hours were significantly lower than the IR group (P ＜ 0.05).The results of pathomorphological examination showed that the hepatic lobules were integrated and the nucleuses were large and round in the control group an d the sham operation group; deformation of the hepatic lobule,smaller cell volume,nuclear condensation and necrosis were observed in the IR group; cell swelling and slight spotty necrosis were detected in the RSM pretreated group.Conclusions RSM could protect liver from damages during IR through up-regulating the expression of p-eIF-2α,reducing the apoptosis induced by endoplasmic reticulum stress.

BACKGROUND:Bone marrow mesenchymal stem celltransplantation has been confirmed to have excellent effect on the treatment of diabetic foot.
OBJECTIVE:To assess the therapeutic effect of bone marrow mesenchymal stem celltransplantation on diabetic foot ulcers and the expression of vascular endothelial growth factor.
METHODS:Literatures concerning the effect of bone marrow mesenchymal stem celltransplantation on foot diabetic and expression of vascular endothelial stem cells were retrieved. Articles that met the criteria were analyzed in depth. Here, we analyzed the experimental research and clinical application of bone marrow mesenchymal stem cells in the treatment of diabetic foot. In experimental studies, rat models of diabetic foot ulcers were established and subjected to bone marrow mesenchymal stem celltransplantation to observe wound healing of ulcers and analyze the expression of vascular endothelial growth factor. In clinical research, the fol ow-up was conducted in diabetic foot patients undergoing bone marrow mesenchymal stem celltransplantation to observe the wound healing of ulcers and adverse reactions.
RESULTS AND CONCLUSION: Experimental studies have shown that bone marrow mesenchymal stem celltransplantation is better than conventional treatment in the treatment of diabetic foot ulcers, but the healing of diabetic foot ulcers is stil slower than that of normal ulcers. After celltransplantation, the expression of vascular endothelial stem cells is elevated but stil lower than that in the normal ulcer controls. Clinical studies have shown that for patients with diabetic foot ulcers, the ulcer wound can be healed after bone marrow mesenchymal stem celltransplantation, as wel as there are no cardiovascular and cerebrovascular diseases, liver and kidney damage and changes in bleeding and coagulation time.

Objective To study the changes in and correlations between the partial pressure of end-tidal carbon dioxide (PETCO2) and the coronary perfusion pressure during cardio-pulmonary resuscitation (CPR) based on the cardiac arrest dog models of ventricular fibrillation by electric shock. Methods 36 healthy dogs were evenly randomized into 3 groups including 4 minutes close-chest CPR(CCCPR) group, 4 minutes open-chest CPR(OCCPR) group, and 8 minutes OCCPR group. There were 12 dogs in each group, half male and half female. In the process of CPR, all parameters about PETCO2 and CPP were recorded. Results In the 4 minutes CCCPR group, the correlation coefficient between the CPP and the PETCO2 was 0.992 (P<0.05), which was in positive linear correlation. In the 4 minutes OCCPR group, the correlation coefficient between the CPP and the PETCO2 was 0.937 (P < 0.05), which also showed positive linear correlation. In the 8 minutes OCCPR group, the correlation coefficient between the CPP and the PETCO2 was 0.952 (P<0.05), and was also in positive linear correlation. The percentage of ROSC was 66.7(8/12) in the 4 minutes CCOPR group, 100%(12/12) in the 4 minutes OCCPR group and 58.3%(7/12) in the 8 minutes OCCPR group. There were statistical differences in CPP, PETCO2 between models with ROSC and without ROSC at 1, 2, 5, 10, 15 and 20 mins of CPR (all P<0.05). Conclusions This research shows that there is a close positive linear relationship between the coronary perfusion pressure and the PETCO2, and PETCO2 could be used to evaluate the prognosis of the CPR.

Objective To investigate the symptoms of diarrhea and the behavior of medical treatment after diarrhea in 2013 in Tianjin City, and provid background information for the future population monitoring. Methods A stratified sam?pling method was used to investigate the symptoms, medical treatment and self medication behavior of 4028 residents in Tianjin. Results The number of people who had diarrhea in 2013 was 324, and the incidence rate of diarrhea was 8.04%. Diarrhea was mainly occurred in May-October (n=241, 74.38%). The incidence of diarrhea was the highest in 60-74 years old group, followed by 75-years old and 0-14 years old groups. The incidence of diarrhea was the lowest in 15-29 years old grouop. A total of 121 patients with diarrhea chose to go to hospital (47.08%), 78 patients chose to buy medicine for treat?ment (30.35%) and 58 patients did not do any disposal (22.57%). Among the patients with diarrhea, the highest proportion of patients chose to go to the first grade and the following medical institutions (68.59%, 83/121). There were 14.05%(17/121) and 17.36%(21/121) patients chose to go to the second and the third levels of medical institutions for the treatment. The av?erage cost for patients with diarrhea was 60 (20, 200) yuan. The purchasing expenditure median was 20 (11,50) yuan. The medical spending was more than the purchase of medicines (Z=2.412, P<0.05). The average cost of medical treatment was more higher in the second and the third levels of medical institutions than that of the first medical institution ( Z=50.709,P<0.05). The average cost of medical treatment was in turn increased for patients with diarrhea treated in Baodi county, Xiqing county, Hangu county and Heping county (Z=74.282,P<0.05). There was no statistical significance in medical expenses be?tween patients with different ages and patient with or without medical insurance. Conclusion There are high incidence of diarrhea in patients under 15 years old and patients over 60 years old. Residents suffering from diarrhea mainly choose their own medicine and the treatment in the first and following medical institutions.

Objective To analyze the National Natural Science Foundation-supported papers on oncology published by domestic authors from 2013 to 2015 and existed problems. Methods The key words in the National Natural Sci-ence Foundation-supported papers on oncology published by domestic authors from 2013 to 2015 and SCI-covered journals and Chinese institutions that published the National Natural Science Foundation-supported papers on on-cology from 2013 to 2015 were analyzed by bibliometrics. Results The number of the National Natural Science Foundation-supported scientific projects and funds, the number of the National Natural Science Foundation-sup-ported papers on oncology published by domestic authors, and the academic level of SCI-covered journals that pub-lished the National Natural Science Foundation-supported papers on oncology from Chinese authors increased year by year from 2013 to 2015 . General and medical colleges and universities with affiliated hospitals or national key laboratories were the leading force in oncology. The hot spots in oncology were focused on basic research and malig-nant tumors. Conclusion The National Natural Science Foundation plays an active role in promoting the develop-ment of oncology in China. Although it-supported papers on oncology published by domestic authors increase year by year, problems are still existed, such as imbalance of institutions that publish papers on oncology and insuffi-cient influencing power of papers published by domestic authors.
