Objective:This study investigates the significance of human papilloma virus (HPV) subtype detection in opportunis-tic screening for cervical cancer in Uygur and Han women. Methods:Flow-through hybridization gene chip and thin-prep cytology test were used to detect HPV in cervical cell samples from 1140 females. A total of 428 patients had undergone cervical biopsies through colposcopy. The diagnostic results of the HPV subtype test for cervical lesions were evaluated on the basis of histology. Results:Total HPV infection rate for the 1140 cervical samples was 30.3%. The most common HPV subtypes were HPV16, HPV58, HPV52, HPV18, and HPV45. HPV52 infection rate was higher in Han women than in Uygur women, with statistically significant differences between the two (χ2=8.737, P=0.003). Among these cervical samples, the single HPV infection rate was 22.4%(255/1140), whereas the multiple HPV infection rate was 6.1% (69/1140). The sensitivity and specificity of the HPV subtype test for cervical lesions were 86.4% and 24.5%, respectively. The positive and negative predictive values were 58.5%and 59.3%. Conclusion:HPV infection subtypes in Ugyur and Han women have unique characteristics. Subtype detection is important in opportunistic screening for cervical cancer.

OBJECTIVETo explore the effect of prostatectomy on nocturia in patients with benign prostatic hyperplasia (BPH).

METHODSThe data of patients who had received prostatectomy for BPH between June 2006 and December 2007 were collected. Nocturia severity was assessed preoperatively and 3 to 6 months after prostatectomy by the number of nocturia events, the time from falling sleep to the first awakening to void (hours of undisturbed sleep, HUS), the score of the nocturia quality of life (N-QOL) questionnaire, the International Prostatic Symptom Score (IPSS) and the quality of life (QOL) score.

RESULTSOne hundred and twenty five cases were included. Of them, 73 patients finished the follow-up completely. There were 62 patients whose number of nocturia events before the operation was equal or more than 2. The data from these 62 patients were analyzed. Of them, 56 patients underwent transurethral resection of prostate, the remaining 11 patients suprapubic prostatectomy. Significant improvement (P < 0.01) was noted in all the following parameters after treatment: the number of nocturia events decreased from 4.2 ± 2.4 to 2.2 ± 1.0, HUS increased from (1.8 ± 0.7) h to (3.0 ± 1.4) h, N-QOL score raised from 30 ± 10 to 40 ± 7, IPSS decreased from 23 ± 5 to 8 ± 5, and QOL score fell down from 4.4 ± 0.7 to 1.5 ± 1.0.

CONCLUSIONThe prostatectomy can markedly improve the symptoms of nocturia, sleep and life quality in the BPH patients who accompanied with nocturia.

OBJECTIVETo investigate the effect of nasal cavity expansion surgery on the abnormal blood supply of the cerebral arterial system.

METHODSFifty-nine inpatients with abnormal blood supply of cerebral arterial system confirmed by transcranial doppler (TCD) and chronic nasal obstructive diseases were included in this study. All patients accepted nasal cavity expansion surgery and were followed-up with TCD every month after operation until TCD became normal, or up to seven months even if the TCD was still abnormal. SPSS 17.0 software was used to analyze the data.

RESULTSIn all 59 patients, there were 164 TCD-abnormal cerebral arteries. Among them, 37 patients(62.71%) with abnormal TCD arteries became normal within 1 to 7 months after operation, 8 patients (13.56 %) got better, but 14 patients (23.73 %) did not improve.

CONCLUSIONSAbnormal blood flow of some cerebral arteries was possibly induced by increasing the activation of sympathetic nervous system around the vertebral arterial system, caused by chronic nasal obstruction. Nasal dilatancy surgery can improve the blood supplement of the cerebral arterial system.

OBJECTIVETo investigate the clinicopathological value of the expression and amplification of P21-activated kinase 1 gene (PAK1) in colorectal carcinoma(CRC).

METHODSImmunohistochemistry (IHC), fluorescence in situ hybridization (FISH) and terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling(TUNEL) methods were used to examine the protein expression, amplification of PAK1 and cell apoptosis in 80 cases of CRC and 30 cases of colorectal adenoma by tissue microarray.

RESULTSIHC showed an overexpression of PAK1 protein in 26% of colorectal adenomas and 62% of CRCs. Significant association was found between expression of PAK1 and tumor histological grade as well as tumor clinical stage(P<0.05). In poor-differentiated(G(3)) CRCs, PAK1 expression in 90% carcinoma was up-regulated, which was significantly higher than that in tumors of G(1/2)(51%). Overexpression of PAK1 was detected in 78% of CRCs in later clinical stages (Dukes C, D), which was significantly higher than that in early clinical stages (Dukes A,B, 53%). In addition, negative correlation between PAK1 overexpression and cell apoptosis was observed in these CRC cohorts(P<0.05). FISH revealed that amplification of PAK1 gene was examined in only 3% CRCs.

CONCLUSIONSOverexpression of PAK1 protein may play an important role in development and progression of colorectal neoplasms and it is closely associated with the malignant histological and invasive phenotype of CRCs. The expression of PAK1 in CRC may be used as one of the new molecular markers in predicting tumors malignant potential and progression.

OBJECTIVETo explore clinical outcomes of patients undergoing emergent coronary artery bypass grafting (CABG) following failed percutaneous coronary intervention (PCI) in the stent era.

METHODSEleven patients who underwent emergent CABG following failed PCI from January, 2002 to December 2010 were enrolled. The in-hospital follow-up included cardiac deaths, Q-wave myocardial infarction, kidney failure, and cerebrovascular events. The clinical end-point of out-hospital follow-up was the major adverse cardiac events including death, myocardial infarction, and target lesion revascularization.

RESULTSThe patients were (61 ± 5) years old. Coronary angiography showed 5 patients had triple vessel lesions. There were 9 target lesions on left anterior descending artery. There were 3 (27.3%) severe calcified, 4 (36.4%) chronic total occlusion, and 4 (36.4%) diffused long lesions. Reasons for emergent CABG were dissection (n = 5, 45.5%), perforation (n = 3, 27.3%), failure to sufficient predilation (n = 1, 9.1%), acute closure (n = 1, 9.1%) and stent loss (n = 1, 9.1%). The average duration of follow-up was (47 ± 33) months. During in-hospital follow-up, there were 1 (9.1%) cardiac death and 2 (18.2%) Q wave myocardial infarction. During follow-up after hospital discharge, 1 patient (9.1%) died of kidney failure, and there was no rehospitalization due to cardiac events.

CONCLUSIONSEmergent CABG after failed PCI often happened in patients with complex coronary lesions. The long term outcome of patients requiring emergent CABG after failed PCI was favorable in this cohort.

BACKGROUNDCurrently available evidence suggests that outcomes are less favorable when left main (LM) bifurcation lesions are treated with 2-stent techniques compared with a single-stent technique. We aimed to evaluate the long-term outcomes of the 2-stent techniques for treating unprotected LM bifurcation lesions in Chinese patients.

METHODSWe enrolled 301 consecutive patients treated with drug-eluting stents (DES) implantation using 2-stent techniques for unprotected LM bifurcation lesions (MEDINA 1, 1, 1, 70.5%). The 2-stent techniques included crush technique, V stenting, T stenting, and Culottes stenting. After stenting, both vessels were redilated at a high pressure before final kissing balloon (FKB). Clinical and angiographic data were analyzed. The primary endpoints were major adverse cardiac events (MACE), which included death, myocardial infarction, and target lesion revascularization.

RESULTSImmediate procedural success was obtained in all cases with a FKB success rate of 95.3%. Follow-up data were available for all patients. The overall incidence of angiographic in-stent restenosis (ISR) rate was 20.3% and most ISRs were of the focal type. During long-term follow-up (mean duration, (54 ± 22) months), the cumulative incidence of MACE was 11.0%, with 8 (2.7%) deaths, 7 (2.3%) myocardial infarctions, and 18 (6.0%) repeated lesion revascularization. MACEs in high SYNTAX score terciles were significantly higher compared with those in low and intermediate SYNTAX score terciles (P = 0.001).

CONCLUSIONSAlthough percutaneous coronary intervention (PCI) with 2-stent technique for unprotected LM bifurcation lesions was accompanied with a slightly high incidence of ISR, the long-term clinical follow-up is acceptable. Technical modifications and stent innovations may further improve both the angiographic and clinical outcomes for patients with LM bifurcation disease treated by PCI.

Processing of Chinese medicinals with vinegar is one of the characteristic processing techniques. Vinegar is vital for the quality of vinegar-processed decoction pieces. However, there have been no specified standards for adjuvants. Through consulting relevant literature and monographs, we comprehensively reviewed the historical evolution of processing with vinegar in records, selection and application of vinegar, and summarized the relevant standards and current status of vinegar as an adjuvant in China. According to the records in literature, vinegar is effective in activating blood, moving qi, dispersing blood stasis, removing toxin, promoting appetite, and nourishing the liver. Traditionally, rice vinegar is chosen in processing. Nowadays, the vinegar made from rice under solid-state fermentation should be chosen. At present, only food standards can be taken for reference for vinegar in the processing. Integrative and specific inspection indicators are lacking, so the standards for adjuvants need to be improved urgently. In addition, the inadequacy in quality control and management is also a major problem to be solved. Through literature research, we reviewed the historical evolution and research advance in vinegar to provide a reference for the standardization and further research of vinegar used in the Chinese medicinal processing.

To analyze the genetic characterization of epidemic rubella virus strains isolated in Liaoning from 2007-2012, a total of 145 rubella virus strains were isolated using Vero/Slam cell line from the patients' throat swabs during rubella outbreaks and sporadics cases in Liaoning Province from 2007 to 2012. Fragments of 945 nucleotides containing 1E gene from 145 rubella virus isolates were amplified by RT-PCR, the PCR products were sequenced and analyzed. Based on the 739 nucleotides of 1E gene, the phylogenetic trees were constructed with 32 WHO rubella reference strains of 13 genotypes downloaded from GenBank and 145 rubella virus strains. The results showed that the 145 rubella virus strains in 2007 -2012 belonged to genotype 1E, nucleotide acids and amino acids similarities were 97.2%-100.0% and 97.6%-100.0%, respectively. Compared to the 1E reference strains(Rvi/ Dezhou.CHN/02, RVi/MYS/01), the nucleotide acids and amino acids similarities were 96.6%-99.2% and 98.2%-100.0%, respectively except for one amino acid change (Val246-Ala246) of RVi/Shenyang. Liaoning. CHN/13.11/13, and Asp262-Asn262 of RVi/Shenyang. Liaoning. CHN/13.11/4 and RVi/Liaoyang. Liaoning. CHN/26. 11/2. there had no change found in the important antigenic epitope sites, the hemagglutination inhibition and neutralization epitopes of the other rubella viruses. All the 145 strains isolated had the same amino acid change (Leu338--Phe338) in E1 protein. These findings suggested that genotype 1E of rubella virus was the predominant genotype in Liaoning province. the rubella prevailed in recent six years was mainly caused by rubella viruses genotype 1E with multi-transmission routes.
