Objective To analyze the diagnostic significance of the expression of perinuclear anti-neutrophil cytoplasmic antibody(pANCA) and anti-Saccharomyces cerevisiae antibody(ASCA) in the patients with inflammatory bowel disease(IBD).Methods Serum samples were collected from 97 patients with IBD,including 86 patients with ulcerative colitis(UC) and 11 with Crohn′s disease(CD).Another group of 36 persons in whom colonoscopic examination was negative served as control.Determinations of ASCA and pANCA were performed using indirect immunofluorescence test(IIFT).Results The positive rate of pANCA in group UC,CD and control was 27.9%,0% and 0%,respectively.Obviously,the rate in group UC was higher than that in the other two groups(P0.05).Four of 11 CD patients(36.4%) were severe cases,among them 3 showed ASCA+;7 were moderate cases(63.6%),and among them 1 case showed ASCA+.The positive ratio of ASCA was significantly different between severe and moderate CD cases(P

ObjectiveTo investigate the feasibility of using the ratio of (Cho + Cr)/Cit derived by MRS to predict the differentiation grades of prostatic cancer and Gleason grading.Methods Five postoperative prostate specimens were spitted and layered according to the region of interest of MRS inspections.The correlation between the CC/C values of each region of interest in each layer and the Gleason scores of the corresponding pathological sections was analyzed.The optimum diagnostic cutoff value was determined by conducting the hypothesis test of the area below the ROC curve of the well and moderately differentiated groups and poorly differentiated ones on the basis of CC/C values with a Spearman test.Results A total of 90 regions with valid pathologic diagnosis were obtained,70 cancer-affected and 20 cancer-free.In MRS,a CC/C value above 0.86 was used as a criterion for defining a cancer-affected region As a result,65 cancer-affected regions and 25 cancer-free regions were identified,among which pathologic diagnosis confirmed 59 and 14,respectively.Spearman′s rank correlation analysis revealed that the CC/C values of the prostatic carcinoma had significant positive correlation with Gleason scores ( r =0.746,P =0.000).For the well and moderately differentiated groups,the hypothesis test about the cutoff value,which was obtained by calculating the area below the ROC curve,was of no statistical significance.For the poorly differentiated groups,the optimum cutoff value was defined as 0.948,and the sensitivity and specificity were 81.4％ and 75.0％,respectively.It was also observed that the Gleason scores of the poorly differentiated endemic regions had positive correlation with the CC/C values ( r =0.605,P =0.000 ),suggesting that CC/C value was associated with the differentiation grade of the poorly differentiated prostatic cancer.When CC/C value was above 0.948,the poorly differentiated prostatic cancer was typically detected and Gleason score was often above 7.Conclusions CC/C values has positive correlation with Gleason scores.MRS may be used to predict the differentiation of prostate cancer.

BACKGROUND: Plasminogen activator inhibitor 1 is the main regulator of the fibrinolytic system in vivo. The increase of plasminogen activator inhibitor 1 is closely related to thrombotic disease and it is also an independent risk factor for development of thrombotic disease.OBJECTIVE: To investigate the effect of huangqi(Astragalus), danggui (Angelica) and ligustrazine as medicines activating blood and eliminating stasis on the expression of plasminogen activator inhibitor 1 in HepG2 hepatocarcinoma cell strain.DESIGN: A randomized controlled study.SETTING: First Cadre Department of General Hospital of Chinese People' s Armed Police Force.MATERIALS: The experiment was completed in Academy of Military Medical Sciences of PLA from August to December 2004. HepG2 hepatocarcinoma cell strain was cultured. According to different drugs in culture medium, they were divided into six groups: control group, huangqi group,danggui group, huangqi + danggui group, compound danshen group and ligustrazine group.METHODS: Huangqi, danggui, huangqi + danggui, compound danshen and ligustrazine were added in HepG2 culture medium respectively. MTS assay was used to detect the effect of medicines activating blood and eliminating stasis on proliferation of HepG2 cells, plasminogen activator inhibitor 1 was assayed by specific enzyme-linked immunosorbent assays(ELISA),plasminogen activator inhibitor 1 activity was measured by amidolytical assay. 0.5 μg/mL of transforming growth factor β1 cells was added in HepG2 culture medium to stimulated production of plasminogen activator inhibitor 1. Control group was treated under the same conditions but without Chinese herbs.RESULTS: The inhibitory rates of cellular proliferation in huangqi and danggui groups werc(6.51 ±2. 66)% and (4.42 ±2. 19)%, but those in huangqi + danggui, compound danshen and ligustrazine groups were (12. 06 ±4. 98)%, (16. 38 ±4.06)% and(32. 83 ±9.8)% respectively,t = 2. 447 - 3. 707, P ＜ 0.05. Compared with the control group, huangqi,danggui, compound danshen and ligustrazine significantly inhibited plasminogen activator inhibitor 1 expression(22.68 ± 2.20, 11.11 ± 1.23,19.66±1.53, 15.45±1.27, 16.90±0.33, 14.01±0.74, t=2.447-3.707, P ＜ 0.05) and activity(2.16±0.014, 2.01 ±0.006, 1.95±0.014, 1.79±0. 104, 1.53±0.045, 1.48±0.012, t =2.447-3. 707,P ＜ 0.05) in HepG2 cells. The evident inhibitory effects were observed in the group of huangqi + danggui, especially in compound danshen and ligustrazine.CONCLUSION: The plasminogen activator inhibitor 1 expression and activity were inhibited effectively by huangqi, danggui, compound danshen and ligustrazine.

The etiological agent of severe acute respiratory syndrome (SARS) was identified as a new coronavirus, termed SARS-CoV. Establishment of an efficient and sensitive diagnostic system of SARS-CoV genetic materials is crucial for SARS control. In this study, we quantified SARS-CoV mRNAs in both infected cell culture lysate and in supernatant by using Real-time quantitative revere transcription-PCR based on EvaGreen鈩?dye and Taqman-MGB probes. For extensive evaluation of sensitivities and specificities, 13 pairs of primers and 4 probes were designed based on different genes of SARS-CoV. Glyceraldehydes-3-phosphate dehydrogenase (GAPDH) was selected as the internal control gene. Results showed that S-gene-specific PCR was the most sensitive for detection, but because of its sequence variability in the different viral strains, primers and a probe based on the N gene were suitable substitutions. Meanwhile, we found the mRNA concentrations in cell culture lysates were much higher than in cell supernatant and facilited more sensitive detection of the SARS-CoV.

BACKGROUND: It is necessary to keep a good cervical curvature for improving nerve symptom in patients with cervical spondylotic myelopathy (CSM). It is verified that cervical anterior plate internal fixation implant is effective to restore the physiological curvature of cervical vertebra.OBJECTIVE: To assess the physiological lordosis of cervical vertebra in CSM patients after cervical anterior plate internal fixation implantation.DESIGN: Observational study.SETTING: First Affiliated Hospital of Nanchang University.PARTICIpANTS: Totally 72 CSM patients were enrolled at Department of Orthopaedics, First Affiliated Hospital,Nanchang University from February 2003 to January 2006, including 46 males and 26 females, aged 45-70 years,averagely 54 years, with the history of 2-6 years. Inclusive criteria included ①cervical spinal cord compression shown in MRI, and ②using autogenous iliac bone. The experiment was approved by Hospital Ethics Committee, and all patients signed the informed consent. Cervical anterior plate was Orion locking plate offered by Shufamo Company. There were single segmental discectomy group (n =32) and two-level segmental discectomy group (n =40) according to experimental requirement.METHODS: ①Anterior decompression plus autogenous iliac bone implant plus titanium plate internal fixation were utilized.The patients were in supine position; shoulder and back were blocked up; neck backward, and endotracheal tube was done under general anesthesia. Transverse or oblique incision was made at right anterior neck. Discectomy decompression was performed with Caspar vertebra ecarteur. Three-dimensional autogenous iliac bone was implanted in decompressed intervertebral space. Immediate stability was obtained after Orion locking titanium plate was fixed, with placement drainage, and then the incision was sutured. ②Postoperative daily activities were conducted with cervical gear, which was removed 8 weeks later. ③Lateral cervical vertebrae X-rays were taken before operation, immediately after operation, 6 and 12 months after operation. Lordosis of the fusion segment was measured with Cobb's angle, and lordosis of cervical vertebra was assessed with D value. These data were analysed by statistic software. ④Bone fusion of the patients was followed up for 12 months after operation. Vertebral fusion standards included no abnormity between two spinous processes of the fusion segment, no lucency between implant and vertebra, as well as bone trabecula across the interface between implant bone and vertebra. ⑤Biocompatibility between material and host was observed during follow-up.MAIN OUTCOME MEASURES: ①Changes of Cobb's angle and D value at different time points before and after operation,and ②Bone fusion and rejection were followed up.RESULTS: Totally 72 patients were involved in the result analysis. ①Cobb's angle was larger and D value was higher immediately after operation, 6 and 12 months after operation than those before operation in the single segmental discectomy group and the two-level segmental discectomy group (P＜0.05). ②Findings of 12-month follow-up showed that bone fusion appeared in all patients of the two groups. ③No significant rejection was found after titanium plate internal fixation implantation. It was found that material and host had a good biocompatibility.CONCLUSION: It is satisfactory to restore physiological lordosis of cervical spine by using cervical anterior plate internal fixation plus autogenous iliac bone for CSM.

Objective To analyse the prognostic factors of ST-elevation acute myocardial infarction men and women. Methods The data of 904 in-hospital patients with ST-elevation myocardial infarction were collected from the database of our hospital during 2003-2004 and 728 of them were followod-up. The patients were divided into groups of male and female. Results Women had more accompanying diseases such as diabetes mellitus (DM) and hypertension than men; left ventricular ejection fraction(LVEF) was lower in female. The rate of successful reperfusion was lower in women than men (P < 0.05). Mortality rate was higher in women. 728(202 female) patients were followed up. The use of β-blockers were statistically different between two groups during follow-up. In the female group, LVEF was lower significantly and the rate of reodmission for heart failure and myocardial infarction as well as that of mortality was higher (P< 0.05). Multivariate analysis showed that sex difference was an independent risk factor for in-hospital mortality (OR = 2. 130,95% CI 0. 954-4.754, P = 0. 045) , but not for mortality in the followed-up period and readrnission. Conclusion There are many factors leading to the poor prognosis of ST-elevation acute myocardial infarction in women. It is essential to pay more attention to its clinical characteristics and begin intervention of the risk factors earlier so as to improve the prognosis.

Objective To analyze the risk factors of malignant glaucoma for primary angle-closure glaucoma(PACG) patients after surgery.Methods Clinical data of elderly patients with PACG who had received surgical treatment at our hospital between 2013 and 2016 were retrospectively analyzed.Patients were divided into two groups according to whether they suffered (Group A) or not (Group B) from malignant glaucoma after surgery.Results A total of 238 patients (315 eyes) were retrospectively analyzed: 17 cases (22 eyes) in Group A and 221 cases (293 eyes)in Group B.The index of axial length, chamber depth and crystal thickness was lower in Group A than in Group B,and the difference was statistically significant(P<0.05).Univariate analysis showed that age under 50, continuous high intraocular pressure, axial length below 22 mm, chamber depth below 2 mm, crystal thickness below 4.5 mm, completely closed anterior chamber angle and chronic angle-closure type were the possible risk factors for malignant glaucoma after surgery (P<0.05).The logistic regression analysis showed that age under 50 and axial length below 22 mm were independent risk factors for malignant glaucoma for PACG patients after surgery.Conclusion PACG patients,especially those who are young or with short axial length,are more vulnerable to malignant glaucoma.

Objective To establish the DNA fingerprint of microflora of some intestinal diseases such as ulcerative colitis (UC),acute gastroenteritis (AG) and irritable bowel syndrome (IBS),and analyze the structural characteristics of such fingerprints. Methods Thirty seven patients with intestinal diseases,definitely diagnosed by coloscopy as UC (20 cases),IBS (6 cases) and AG (11 cases),and 11 healthy people as control were involved in the present study. The total DNA was extracted from the fecal samples,and enterobacterial repetitive intergenic consensus sequence-polymerase chain reaction (ERIC-PCR) was used to set up the DNA fingerprint of intestinal microflora. The differences existed among the fingerprint profiles of intestinal microflora were compared. Results The numbers of DNA bands were obviously less in UC patients than in IBS and AG patients and healthy subjects,implying that significant differences existed in the intestinal microflora among UC and AG patients and healthy subjects. The principal band of DNA fingerprint in 17 UC patients appeared at 0.7kb,and 2 main DNA bands existed at 0.8kb and 1.1kb in AG patients,while no principal band was found in the DNA fingerprint of the IBS patients and healthy subjects. Conclusions It is likely that a single principal microflora is presented in the intestinal tissue of UC patients,which might be responsible for the morbidity of UC.

Objective To investigate the relationship between the appearance of donor cells in urine and acute rejection and the clinical implication. Methods Eighty renal transplantation patients were observed, in which the donors were male and the recipients were female, or HLA DR antigen were mismatched (30 cases were at perioperative period, 20 cases were subjected to acute rejection, 30 cases had stable renal function). Urine samples were collected regularly. PCR and PCR SSP were applied to detect DYZ 1 (special gene fragment of Y chromosome) and DRB 1of HLA DR antigen respectively after DNA were obtained.Results Perioperative period group: donor cells in urine were detected in all the patients 24?h after operation. With the development of disease, the intensity of donor DNA expression in urine was decreased generally. 30 days later, donor cells in urine disappeared only in 3 cases of 30 cases, and acute rejection happened in 8 cases of the rest 27 cases. Acute rejection group: donor cells in urine were detected in 18 cases (90%); 2 weeks following anti rejection therapy, donor cells in urine were negative only in 3 cases, still positive in the other 15 cases, and the intensity of donor DNA expression in urine was decreased generally during the treatment. Donor cells in urine were negative in 16 cases ( 88.9% ) after treatment for 3 months. Stable renal function group: DYZ 1 or HLA DRB1 was positive in 2 cases ( 6.7% ), negative in 28 cases ( 93.3% ). Conclusion PCR and PCR SSP were used to detect DNA of donor cells in urine, which would be a new method to diagnose acute rejection of renal transplantation, but would not exactly fit for those happened in early stage. The intensity change of donor DNA expression in urine represented the recovery of renal transplantation, which provided the possibility to evaluate renal allograft rejection quantitatively at the same time.
