Objective To investigate the expression and pathological diagnostic utility of ?-methylacyl-coenzyme A racemase(P504S)in prostate cancer(PC). Methods The specimens of 42 cases of PC,18 cases of prostatic intraepithelial neoplasia(PIN)and 25 cases of benign prostatic hyperplasia(BPH)tissues were immunohistochemical stained with P504S,34?E 12 and vascular endothelial growth factor(VEGF)antibody,respectively. Their staining extent and intensity were analyzed and compared. Results Of the 42 PC cases,33(79%)showed positive P504S staining with moderate to strong staining intensity, which was significantly stronger than that of PIN and BPH cases,while adjacent normal glands were all negative. Weakly positive P504S staining was found in 6(33%)of 18 PIN cases and 2(8%)of 25 BPH cases,while it was negative in others.The specimens of BPH cases had a complete basal cell layer and were positive for 34?E 12 ;while 40 cases of PC had no basal cell layer and only 2 cases had discontinuous basal cell layers with weak staining.The basal cell layers of PIN cases were positive for 34?E 12 and the staining was a little weaker than that of BPH cases.All the specimens of BPH,PIN and PC cases showed positive staining for VEGF,the extent and staining intensity had no significant difference among these groups. Conclusions P504S has high sensitivity and good specificity in the diagnosis of PC,and is helpful for differentiating the suspected cases when combined with 34?E 12.

Objective To evaluate the epidemiology, prophylaxis and treatment of bacterial infections after orthotopic liver retransplantation.Methods A retrospective study on bacterial infections in 22 patients undergoing othotopic liver retransplantation was carried out.Results Bacterial infections were confirmed in 8 of 22 preoperation and in 20 of 22 (90.9 %) postoperation. The median time of bacterial infections was 7 days after liver retransplantation. Fifty-one pathogenic organisms including 25 types were separated. The most commonly seen infected sites were biliary tract (50.0 %, 11/22), abdomen (45.4 %, 10/22), respiratory tract (36.4 %, 8/22), blood (31.7 %, 7/22), incision ((9.1) %, 2/22), bowel (4.5 %, 1/22), veins with venipuncture (4.5 %, 1/22). Seven cases of sepsis died.Conclusion The infectious rate after liver retransplantation is high and the types of bacterial disseminating loosely on organs are varied. The mortality will be increased if the patients develop sepsis. Reasonable use of immunosuppressants, selection of antibiotics and the supporting therapy are the keys to prevent and treat infections following liver retransplantation.

Aims To construct the N-terminal Strep-tagged ( NS-tagged) fusion protein expression vector, and to apply the vector to express NS-tagged fusion proteins of Chlamydia RNA polymerase subunit. Meth-ods By using PCR method, NS fusion protein tag and a new multiple cloning sites (MCS) were inserted into pET21c-DH plasmid by primers to replace the original T7 protein tag and MCS. The newly introduced Not I cutting site was chosen for self-ligation of PCR prod-uct. Then, the cyclized PCR product was transformed into DH-5α competent cells. The positive clones were selected by PCR and sequencing. To get NS-tagged fu-sion proteins of chlamydial RNA polymerase subunits, the α, β and β′ subunits were inserted between BamH I and Sal I cutting sites of the newly constructed ex-pression vector. Then, the NS-α, NS-β and NS-β′ ex-pression vectors were transformed into Arctic Express expression cells. The fusion protein expression statuses of transformed cells were identified by Commassie blue staining and Western blot. Results The NS-tagged fusion protein expression vector pET21c-NS-MCS was successfully constructed, and NS-α, NS-β and NS-β′fusion proteins were obtained by using this newly con-structed expression vector. Conclusions In this pro-ject, we constructed an NS-tagged fusion protein ex-pression vector and applied it to express NS-α, NS-βand NS-β′ fusion proteins. Our study can lay a solid foundation for the study of transcriptional regulation of Chlamydia genes.

Objective To investigate the diagnostic significance of the relative band power(RBP) of EEG in acute focal cerebral ischemia (AFCI). Methods EEG monitoring was performed in 20 patients with AFCI (51 lesions) in neurological intensive care unit (NICU) and 20 patients with normal EEG (control group) in NICU. The changes of bilateral RBP were observed and analyzed comparatively. RBP in the infarction group was compared with that in the control group. The diagnostic capabilities of all wave-band RBPs were assessed with the receiver operating characteristic (ROC) analysis. Results AFCI shoved asymmetry on all the wave-band RBPs. The RBP of of δwave on the lesion side was significantly higher than that on the normal side (P <0.01). RBPs of α, β and θ waves were decreased significantly (P <0.05). RBP of δ wave in the infarction group was increased significantly compared to the control group (P < 0.01 ). RBPs of α and β waves were decreased significantly (P <0.01). The diagnostic accuracy of the RBP of α was the highest, and both β and δ waves also had significance for the diagnosis of AFCI. Conclusions RBP had an important significance for the early diagnosis of AFCI. Conclusions RBP had an important significance for the early diagnosis of AFCI.

Objective To analyze the correlative factors of peptic ulcer recurrence in the elderly. Methods From January to December 2009,169 elderly patients (≥ 60 years old)with peptic ulcer delected by edoscopy were enrolled,whose treatment and usage of medication were analyzed.Data of treatment and recurrence in 3-year follow-up were recorded.Mann-Whitney rank sum test and Logistic regression analysis were performed to analyze the correlated factors.Results The potential risk factors associated with recurrence of peptic ulcer in the elderly were screened and analyzed by single factor analysis,and ulcer size, ulcer location, concomitant usage of drugs, smoking and condition of Helicobacterpylori (H .pylori )infection at the end of follow-up were found to be correlated with recurrence of peptic ulcer in the elderly.After adjusting age and gender,the potential risk factors were analyzed by a Logistic stepwise regression model.Smoking (OR = 1 .788,P = 0.001 ),combined medication (OR=6.202,P =0.015 ),ulcer size (OR =2.697,P =0.032 )and condition of H .pylori infection at the end of follow-up (OR=43.784,P =0.007)were found to be correlated with recurrence of peptic ulcer in the elderly.Conclusion Smoking,combined medication,ulcer size and condition of H .pylori infection at the end of follow-up have an impact on peptic ulcer recurrence in the elderly.

BACKGROUND: Both Allergic rhinitis and bronchial asthma are allergic diseases of respiratory tract. They frequently coexist in the same patients.OBJECTIVE: To study the incidence of allergic rhinitis in patients with bronchial asthma in Nanjing, and to analyze the correlation of clinical characteristic between allergic rhinitis and bronchial asthma.DESIGN: The questionnaire survey.SETTING: Department of Otorhinolaryngology-Head and Neck Surgery and Department of Respiratory, Nanjing General Hospital of Nanjing Military Area Command of Chinese PLA.PARTICIPANTS: A total of 134 patients with bronchial asthma including 73 males and 61 females were selected form Nanjing General Hospital of Nanjing Military Area Command of Chinese PLA from February 2001 to April 2005. Their ages ranged from 3 to 72 years. Severity of asthma of all patients was classified based on Global Initiative for Asthma (GINA). The diagnostic criteria of allergic rhinitis were established referred to the guideline of Haikou Meeting (November, 1997). All patients provided the confirmed consent.METHODS: The questionnaire survey of 134 bronchial asthma patients from the city of Nanjing was conducted. Their age, classification, severity, treatment status, and the family history of all 134 patients were investigated in details. Differences of age, age at onset, and course of disease between rhinitis and asthma of all patients were examined by two independent t tests. The correlation between clinical characteristics of allergic rhinitis and bronchial asthma was analyzed by Spearman rank correlation.MAIN OUTCOME MEASURES : Incidence of allergic rhinitis in patients with bronchial asthma and the correlation of clinical characteristic between allergic rhinitis and bronchial asthma.RESULTS：Of all 134 bronchial asthma patients，82(61．2％,82/134)were accompanied with allergic rhinitis．There were 45 males and 37 females．Of 82 patients with allergic rhinitis accompanying with bronchial asthma，severity was classified into grade Ⅰ (mild pause,n=56)，grade Ⅱ (mild persistence，n=21)，grade Ⅲ (moderate persistence，n=4)，and grade Ⅳ (severe persistence，n=1)．In addition,allergic rhinitis was classified into periodicity (n=65) and persistence(n=17)．According to the classification and seventy system recommended in ARIA,63 patients had mild symptoms and 19 had moderate and severe symptoms．Severity of allergic rhinitis was positively related to that of bronchial asthma(r=0.689,P＜0．01)．CONCLUSION: The morbidity of allergic rhinitis combining with bronchial asthma is high in Nanjing, China. While, their classification and severity are highly coherent.

Objective To study the diagnosis and surgical treatment of Mirizzi syndrome (MS).Method The clinical data of patients with Mirizzi syndrome treated in our center from July 2001 to July 2011 were retrospectively studied and the diagnostic methods,operative strategies and outcomes of surgical treatment were analyzed.Results Mirizzi syndrome (MS) was identified in 56 out of 13800patients who received cholecystectomy (0.4％). MS was diagnosed preoperatively in 30 patients (53.6％).There were 29 patients with Mirizzi syndrome type Ⅰ,17 patients with type Ⅱ,9 patients with type Ⅲ,and 1 patient with type Ⅳ using the Csendes's classification.In two patients (3.6％) coincidental gallbladder carcinoma was detected.An initial laparoscopic approach was attempted in 33patients,and 16 were converted to open surgery.The remaining 23 patients underwent open operation.Surgical procedures included cholecystectomy,choledochotomy and T-tube insertion,simple closure and drainage (via T tube) of the biliary fistula,Roux-en-Y hepaticojejunostomy,radical resection of gallbladder and hepaticojejunostomy.Inadvertent bile duct injury occurred in 2 patients who had an initial laparoscopic approach for a preoperative undiagnosed MS. Postoperative morbidities included biliary leak (n =4) and residual common bile duct stone (n=2).All patients recovered completely and there was no hospital mortality.Conclusions Preoperative diagnosis of Mirizzi syndrome is still challenging despite the availability of multiple imaging modalities.Open surgery remains the standard of care,although laparoscopic treatment may be used in selected patients,especially for type Ⅰ Mirizzi syndrome.Patients with Mirizzi syndrome should be managed differently,basing on intraoperative findings and the type of Mirizzi syndrome.
