Objective To investigate the relationship between chronic prostatitis and the coagulase-negative staphylococci (CNS),and to study the diagnostic value and clinical significance of CNS in expressed prostatic secretion (EPS). Methods Overall,428 patients with chronic prostatitis were included in this study.Their mean age was 31 years (range,18 to 46 years).The mean cause was 6 months (range,3 to 32 months).The mean NIH-CPSI score was 23.2.Bacterial culture and antimicrobial agent sensitivity test were applied to samples from the 428 patients.The samples were taken with 4 tubes from the lower urinary tract segmented by Meares-Stamey method. Results Bacteria were found in 248 patients (57.94%) out of 428 ones.Gram-positive bacteria were found in 195 cases(78.63%).In the 195 cases,staphylococci were found in 160 cases(64.25%,160/248).CNS were found in 89 cases(35.89%,89/248),most of which were epidermidis staphylococci 81 cases(32.66%).The next were saprophytic staphylococci 3 cases and hemolytic staphylococci 2 cases.There was no correlation between NIH-CPSI score and bacterial culture results.The sensitivity test results showed the rate of drug resistance of CNS from EPS was high for ?-lactamases,quinolones and aminoglycosides(51.9% to 100%). Conclusions The results suggest that CNS is a main kind of pathogen of chronic prostatitis,so considerable attention should be paid to it.In addition,it is of significant importance to apply bacterial culture and sensitivity test in EPS to the diagnosis and treatment of chronic prostatitis.

Objective To evaluate the therapeutic effect of recombinant human granulocyte-macrophage colony stimulating factor ( rhGM-CSF) combined with sulfadiazine silver ( SD-Ag) unguent on deep second degree burn. Methods Eighty-nine patients with deep second-degree burn (burns areas<10%) were enrolled.These patients were divided into two groups at random (Group A and Group B).The patients in Group A were treated with SD-Ag unguent only, and those in Group B were treated with rhGM-CSF and SD-Ag unguent.The therapeutic effects and the adverse drug reaction were recorded. Results The healing time in Group A [(19.79±1.47) days] was obviously shorter than that in Group B [(15.76±1.63) days].The total wound healing rates in Group B [on day 9:(76.41±3.24)%, day 13:(95.01±1.43)%, day 16:(99.54±0.88)%, and day 21 (100.00±0.00)%] were higher than those of Group A [on day 9: (67.24±2.33)%, day 13: (75.54±1.11)%, day 16:(88.33±1.32)%, day 21:(99.14±1.95)%].During the treatment, there was no obvious adverse reaction was observed in the two groups. Conclusion The application of rhGM-CSF combined with SD-Ag unguent can not only accelerate the healing rates of deep second-degree burn, but also has curative effect with safety.

Background The optic quality of Toric intraocular lens (IOL)-implanted eye is affected by the residual astigmatism and individual difference of corneal spherical aberration and different magnification from steep and flat axis refraction.Whether correcting Toric IOL spherical aberration can effectively improve the image quality of individual patient is a question to be studied.Objective This study attempted to collect eye parameters of cataract patients to reconstruct the customized vision model by using Zemax optical software,and to evaluate the image performance with different Toric IOL spherical aberration.Methods A prospective study was performed.Forty-five eyes of 45 cataract patients were included in Second Hospital of Hebei Medical University from August 2012 to October 2013.Several relevant parameters were measured by Pentacam,including anterior and posterior surface height of cornea,corneal thickness,curvature radius of flat and steep meridians of anterior surface astigmatism,refractive diopter and curvature radius of posterior surface.The astigmatism of anterior and posterior corneal surface was described by Matlab 4.5 software.Corneal astigmatism model were set as aspheric state,and the effective position of Toric IOL was calculated using Holladay Ⅰ formula.Customized individual model eyes were constructed by Zemax software.The contrast sensitivity function (CSF) of different spherical Toric IOLs at different spatial frequencies were calculated and compared between 300 Td light environment with 3 mm pupil diameter (photopia light) and 0.3-1.0 Td light environment with 5 mm pupil diameter (mesopia light).This study was approved by Second Hospital of Hebei Medical University ethics committee,all the patients signed the informed consent.Results The mean astigmatism power was (1.51 ± 0.36) D and (1.49 ± 0.37) D,and the mean astigmatism meridian was (101.5 ± 59.8) ° and (101.9±58.5) ° in the model eyes and cataract eyes,respectively,without significant differences between them (t=0.886,0.652;both at P＞0.05).Bland-Altman test showed a good agreement in astigmatism power and astigmatism meridian between model eyes and cataract eyes.The LogCSF values at 1.5,3.0,6.0,12.0 and 18.0 c/d spatial frequencies were significantly higher in the aspherical Toric IOL model eyes than those in the spherical Toric IOL model eyes,and the LogCSF values at various spatial frequencies were significantly higher in the Toric IOLs with spherical aberrations of-0.13 μm and-0.26 μm than those in the zero spherical aberrations in both photopia light and mesopia light (all at P＜0.05).Conclusions A precise corneal astigmatism model based on cornea high data of cataract eyes was successfully constructed through special formulas with Zemax software.Aspherical Toric IOL can compensate for spherical aberration of cornea and enhance the optic quality in individual model eye.

Background Pentacam anterior segment analysis system (Pentacam) is more accurate in the quantitative evaluation of ocular anterior segment in primary angle-closure glaucoma (PACG) eyes than slit lamp microscope and ultrasound biomicroscope (UBM).However,its accuracy in the earlier stage of PACG before and after YAG laser peripheral iridotomy (LPI) is not fully elucidated.Objective This study was to assess the effect of YAG LPI in PACG patients with Pentacam.Methods A prospective self-controlled study was performed.Thirtyfive fellow eyes (pre-clinical stage of PACG) of acute PACG and 35 fellow eyes of chronic PACG were included in the Second Hospital of Hebei Medical University from July,2012 to December,2013.YAG LPI was performed on the eyes,and the parameters of ocular anterior segment including central anterior chamber depth (ACD),anterior chamber volume (ACV) and peripheral anterior chamber angle (ACA) were measured and compared by Pentacam before and 1 day,7 days,28 days after operation.This study was approved by the Ethic Committee of the Second Hospital of Hebei Medical University and informed consent was obtained from all subjects.Results In pre-clinical stage of PACG eyes,the postoperative ACD and ACV values were increased in comparison with preoperation,showing significant differences among various time points (ACD:F =6.783,P =0.004;ACV:F =19.090,P =0.000),and no significant difference was found in ACA among different time points (F =0.153,P =0.928).In the fellow eyes of chronic PACG,the postoperative ACD and ACV values were larger than those of preoperation,with significant differences among various time points (ACD:F =21.576,P =0.000;ACV:F =47.506,P =0.000),and no significant difference was found in ACA among different time points (F=0.581,P=0.629).The change values of ACD and ACV were (0.064±0.022) mm and (27.840±4.963) mm3 in the eyes of pre-clinical stage of PACG,and those in the fellow eyes of chronic PACG were (0.047-± 0.020) mm and (21.000 ± 3.278) mm3,showing significant differences between the two groups (ACD:t=2.783,P=0.008;ACV:t=5.749,P=0.000).Conclusions Pentacam allows easy,fast,automatic and non-contact quantification and three-dimension image of the anterior chamber parameters before and after YAG LPI in pre-clinical stage of PACG eyes and fellow eyes of chronic PACG.The ACD deepens and ACV increases after LPI in glaucomous eyes,especially in the pre-clinical stage of PACG eyes.

Objective To investigate the effect of solute cartier organic anion transporter family, member 1B1 (SLCOIBI) gene variants on the response to therapy with repaglinide in type 2 diabetes. Methods 100 newly-diagnosed type 2 diabetic patients were treated with repaglinide during a course of 48 weeks. Anthropometrie parameters and indices related to glucose metabolism were measured periodically. Genotypes of SLCO1B1 D130N and V174A were detected by PCR-restriction fragment length polymorphism (RFLP) and sequencing respectively. Results Eighty-nine patients accomplished the 48-week follow-up visits. D130N variant in SLCO1B1 gene was associated with repaglinide treatment, DD genotype had better HbA1C lowering effect than N allele carrier [△HbA1C: (-2.29±0.23) % vs (-1.49±0.21)%, P<0.05]. No association was detected between D130N and the other effects of repaglinide on glucose metabolism related phenotypes. Conclusion D130N variant in SLCO1B1 gene is associated with the response to repaglinide treatment in patients with type 2 diabetes. DD homozygotes had a better effect than N allele carriers.

Objective To explore the effect of hepatitis B virus(HBV) on the expression of apolipoprotein B(ApoB) and its regulatory mechanism. Methods mRNA and protein expression of ApoB in HepG2 and HepG2.2.15 cells was measured by RT-PCR and Western blot, serum ApoB levels in patients with HBV infection and in healthy individuals were measured by biochemical analyzer Olympus 5400, the expression of ApoB difference among healthy individuals, patients with chronic hepatitis B, liver cirrhosis, and hepatocellular carcinoma were analyzed, HBV infectious clone pHBV1.3 was tranfected into HepG2 cells,and expression of ApoB and microsomal triglyceride transfer protein(MTP) was measured by RT-PCR and Western blot. Results Expression of ApoB mRNA and protein was lower in HepG2.2.15 cells than in HepG2 cells, serum apoB levels was much lower in patients with chronic hepatitis B and liver cirrhosis as compared to healthy individuals( P ＜0.05 ), HBV could inhibit the expression of ApoB and MTP at mRNA and protein levels. Conclusion HBV may downregulate the synthesis and secretion of ApoB via inhibits the expression of MTP.

Objective To compare the differences of metabolic syndrome (MS) prevalence by using four working definitions and their relationship with obesity-related indicators in first-degree relatives of type 2 diabetes mellitus pedigrees. Methods Totally, 2 372 first-degree relatives from 715 type 2 diabetic pedigrees were selected in this study. Complete laboratory data, including blood pressure, lipid profile and plasma glucose, were collected. The prevalence rates of MS and obesity of four definitions, as defined by National Cholesterol Education Program Adult Treatment Panel Ⅲ (ATPⅢ) in 2005, International Diabetes Federation (IDF) in 2005,Chinese Diabetes Society (CDS) in 2004 aml Joint Committee for Developing Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults (JCDCG) in 2007,were analyzed. Results (1)The prevalence rates of MS were 45.40% ,38.74% ,25.08% and 39.29% aecording to four definitions respectively. The prevalence rates of MS were higher in females than in males by using ATPⅢ and IDF definitions (both P<0. 01). (2)The common comhinations of metabolic abnormality was dyslipidemia, hypertension, obesity and hyperglycemia by using four definitions,except in females by using CDS definition. (3)The prevalence rates of obesity were 58.18% ,58.18% ,33.90% and 42.96% acconling to the four definitions respectively. The prevalence rates of MS in obese subjects were 66.59% ,66.59% ,54.85% and 68.99% according to four definitions respectively. (4) Applying the cutoff point for abdominal obesity according to ATPⅢ, IDF and JCDCG definitions, the prevalence rates of abdominal obesity in subjects with body mass index (BMI) <25 kg/m2 were respectively 28.58% and 16.78%, being higher in females than in males(38.90% vs 15.02% ,21.01% vs 11.22% ,both P<0. 01). Conclusion (1)There is significant familial aggregation of MS and obesity,and the first-degree relatives of type 2 diabetic patients are high risk populations. (2) Waist circumference rather than BMI taken as a discriminating component of obesity in MS seems to be clinically more helpful to the early identification and prevention of MS.

Objective To analyze the patterns and distribution of lymph node metastasis in patients with adenocarcinoma of the esophagogastric junction ( AEG). Methods The pathological data of 393 patients with AEG from 2006 to 2009 were analyzed. The patterns and distribution of lymph node metastasis were analyzed in patients with different Siewert subtypes, depths of tumor invasion, and maximum diameters of the tumor, and the high?risk lymphatic drainage areas were investigated. Between?group comparison was performed by χ2 test. Results The metastatic rate and ratio of abdominal lymph nodes in AEG were 69?? 2%and 31?? 31%, respectively. The incidence rates of lymph node metastasis in the cardia, lesser curvature, left gastric artery, splenic artery, splenic hilum, mesenteric root, and abdominal aorta were the highest. The metastatic rate and ratio of mediastinal lymph nodes were 16?? 4% and 8?? 3%, respectively. The incidence rates of lymph node metastasis in the lower paraesophageal, esophageal hiatus, and superior diaphragmatic areas were the highest. Compared with Siewert type II and type III AEG, Siewert type I AEG had a significantly higher mediastinal lymph node metastatic rate (P= 0?? 003) and a significantly lower abdominal lymph node metastatic ratio (P= 0?? 002).The metastatic ratios of lymph nodes in multiple abdominal regions were higher in patients with stage T3+T4 AEG and a maximum tumor diameter of ≥6 cm than in the control group, while the metastatic ratios of mediastinal lymph nodes in groups with different maximum tumor diameters were similar. The metastatic ratios of lymph nodes in the greater curvature, hepatoduodenal ligament, and inferior diaphragmatic areas were lower than 10% in all groups. Conclusions In radiotherapy for AEG, the abdominal high?risk lymphatic drainage areas involve the cardia, lesser curvature, left gastric artery, splenic artery, splenic hilum, mesenteric root, and abdominal aorta, while the mediastinal high?risk lymphatic drainage areas involve the lower paraesophageal, esophageal hiatus, and superior diaphragmatic areas. In addition, the personalized target volume design should be based on the patterns of lymph node metastasis with different Siewert subtypes and clinical pathological characteristics.

Objective To investigate the association of activating transcription factor 6(ATF6)gene Ala145Pro(GCG→CCG)variant with glucose and lipid metabolism in Chinese.Methods The genotypes were determined by PCR-RFLP in 689 Chinese in Shanghai.Among them,361 subjects showed normal glucose regulation,250 cases were newly-diagnosed diabetic patients without taking any drug and 78 cases were probands of early-onset type 2 diabetes pedigrees.The following phenotypes were measured:body height and weight to calculate BMI;waist,hip and femoral circumference to calculate waist-to-hip ratio and waist-to-femoral ratio;blood pressure;plasma glucose levels obtained at 0 and 120 minute during 75 g oral glucose tolerance test;fasting serum lipid profile including total cholesterol,triglyceride,high density lipoprotein-cholesterol and low density lipoprotein-cholesterol;body fat percentage and distribution.Results(1)The frequency of C allele is significantly lower in probands from early-onset type 2 diabetes patients compared with subjects with normal glucose regulation(P=0.035).(2)In subjects with normal glucose regulation,the CC+CG genotype had a significantly lower level of high density lipoprotein cholesterol as compared with GG genotype(P=0.014).(3)In type 2 diabetic patients,the CC+CG genotype had a significantly higher level of low density lipoprotein-cholesterol as compared with GG genotype(P=0.041).Conclusion These findings suggest that variant of ATF6 plays a role in glucose and lipid metabolism in Chinese.
