Objective To study reliability and validity of incontinence impact questionnaire short form (IIQ-7) in the Chinese population. Methods IIQ-7 form was translated into Chinese; 74 patients with urinary incontinence completed the IIQ-7 simplified Chinese version and short-form 12-item health survey (SF-12) questionnaires. The urinary incontinence patient also ran a 1 hour pad test. Then, reliability and validity of those forms were analyzed. Results The Cronbach's alpha of IIQ-7 simplified Chinese version was 0. 824 (P <0. 01). The intra-class correlation coefficient of IIQ-7 simplified Chinese version was 0. 749 (P < 0.01) . IIQ-7 simplified Chinese version scores were negatively correlated with SF-12 scores (Spearman correlation coefficient: - 0. 570, P < 0. 01) , IIQ-7 simplified Chinese version scores were positively correlated with 1 hour pad test (Spearman correlation coefficient: 0.461, P < 0. 01) , IIQ-7 simplified Chinese version scores were also positively correlated with the course of disease (Spearman correlation coefficient: 0. 235 , P < 0. 05) . Factor analysis of IIQ-7 simplified Chinese version showed good construct validity. Conclusions The simplified Chinese version of IIQ-7 has higher reliability and validity in the Chinese population. They are highly recommended for clinical treatment and research.

Objective To evaluate the effectiveness and safety of partial splenic embolization using polyvinyl alcohol versus gelfoam to treat hypersplenism in cirrhotic patients.Methods A literature search was performed in databases which included PubMed,Embase,Cochrane library,Sinomed,CNKI,Wangfang data and VIP for trials on partial splenic embolism using PVA or gelfoam to treat hypersplenism in cirrhotic patients.The study was censored in May 2016.After data extraction and assessment of quality,a meta-analysis was performed using the RevMan 5.3 software.Results Five studies which involved 197 patients were selected in this study.Included into the PVA group were 92 patients and the gelfoam group 105 patients.On Meta-analysis,the PVA group had a higher value of WBC a month after PSE (WMD =0.4,95％ CI:0.05 ～ 0.75,P ＜ 0.05),higher values of WBC (WMD =0.39,95％ CI:0.06 ～ 0.71,P ＜0.05) and PLT (WMD =8.08,95％ CI:1.65 ～ 14.51,P ＜ 0.05) on month 6 post-embolization.The degree of post-embolization pain was more severe (RR =1.32,95％ CI:1.14 ～ 1.54,P ＜ 0.05) and the length of painful time was longer (RR =2.01,95％ CI:1.36 ～ 2.66,P ＜0.05) in the PVA group.There were no significant differences in the values of PLT,fever and complications (all P ＞ 0.05).Conclusions PSE using PVA achieved better short-term and long-term results in hematological indicators than gelfoam.However,the degree and extent of duration of pain were significantly longer.

OBJECTIVEUsing regional assignment to forked method to study lumbar intervertebral disc hemiation (bugle, hernia, prolapse) dependablity and reason of lumbar intervertebral disc herniation and asymptomatic lumbar intervertebral disc herniation.

METHODSFrom March 2005 to October 2006, 120 patients of match condition from orthopaedics dept and rehabilitative dept of the Boai hospital of Longyan were studied. All patients were equally divided into two groups according to whether or not accompany with symptom of lumbar intervertebral disc herniation. There was not statistical difference in sex, age, course of disease, segment of intervertebral disc between two groups. Sixty patients of symptomatic lumbar intervertebral disc herniation were equally divided into three groups according to (bugle, hernia, prolapse) image on CT. Sixty patients of asymptomatic lumbar intervertebral disc herniation were equally divided into three groups according to (bugle, hernia, prolapse) image on CT. The age was 20-59 years old with an average of 38.5 years. Using regional assignment to give a mark respectively for every group. The sagittal diameter index (SI), anterior diastema of flaval ligaments, the width of superior outlet of latero-crypt, anteroposterior diameter of dura sac were respectively measured by sliding caliper. CT value and protrusible areas were respectively evaluated by computer tomography. Adopting mean value to measure three times.

RESULTS(1) There were not statistical difference in SI, CT value, hernia areas, anteroposterior diameter of dura sac between two groups (symptomatic lumbar intervertebral disc herniation and asymptomatic lumbar intervertebral disc herniation). There were statistical difference in the width of superior outlet of latero-crypt, anterior diastema of flaval ligaments between two groups (symptomatic lumbar intervertebral disc herniation and asymptomatic lumbar intervertebral disc herniation). (2) There were statistical difference in protrusible type,protrusible segment between two groups (symptomatic lumbar intervertebral disc herniation and asymptomatic lumbar intervertebral disc herniation).

CONCLUSIONThere were not necessary relationship between in protrusible size, location, type, compression degree and clinical symptom. This paper may support the mechanism of lumbar intervertebral dise herniation that associated with the following the three aspects: (1) spinal reserve capacity (SRC); (2) involved nerve roots escaping from herniated disc compression and its elastic lengthening function; (3) hypoxia symptosis and anti-ischemia injury compensation of involved nerve roots.

Objective To explore the value of intra-voxel incoherent motion diffusion weighted imaging(IVIM-DWI)in brain perfusion of early hypertensive patients. Methods Totally 36 hypertensive patients and 14 volunteers were recruited and scanned using routine MRI sequences including axial T2WI, T1WI, T2FLAIR, TOF-MRA and IVIM-DWI sequence. Perfusion-related diffusion coefficient (D*) values and perfusion fraction (f) values in various regions were measured separately.The independent sample t test was used to analyze the data.Results Compared with the volunteers,both D*values and f values in lenticular nucleus,thalamus,superior frontal gyrus,occipital lobe,genu of corpus callosum(CC)and posterior horns of periventricular WM, were found to be lower (P<0.05) in hypertensive patients. For other regions, there were no significant difference(P>0.05).Conclusion IVIM-DWI has the ability to detect subtle brain perfusion abnormalities at early stages of hypertension.It has an important value to the prevention and treatment of hypertensive encephalopathy.

OBJECTIVE: To explore a simple and accurate method for localization of upper airway obstruction in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) and provide instructions for surgical treatment. METHOD: Fifty OSAHS patients confirmed by PSG underwent acoustic rhinometric and pharyngometric assessment by Eccovision. The parameters were recorded, including nasal minimal cross-sectional area (NMCA), distance of MCA from the nostril (DCAN), minimum cross-sectional area at the nasal valve(MCA), nasal resistance (NR) and nasal volume from 0 to 6 cm from the nostril (NCV), as well as pharyngeal cross-sectional area (CSA) and volume from 4.8 to 15.0 cm. The sensitivity and specificity of acoustic rhinometry and pharyngometry on localization of airway obstruction was determined by a comprehensive imaging and endoscopic study. RESULT: In 50 cases with severe OSAHS, NMCA, DCAN, MCA, NCV, NR were (0.61 +/- 0.35) cm2, (2.06 +/- 0.12) cm, (0.87 +/- 0.12) cm2, (9.24 +/- 2.31)cm3 and (0.51 +/- 0.32)kPa/(L x min), respectively. Pharyngeal CSA and volume were statistically significantly lower than that in control group (P < 0.01). The value of DCAN was (2.06 +/- 0.12) cm, (9.50 +/- 4.08) cm, (13.10 +/- 2.52) cm in type I II, III patient, respectively. Compared with the control group, the difference was statistically significant. CONCLUSION Acoustic rhinometry and pharyngometry is a simple and safe method in localization of airway obstruction in patients with OSAHS.

To perform a comprehensive analysis of the pathogenic causes of a food poisoning case in a district of Wuhan Cit-y,we investigated the molecular epidemiological relationships among pathogenic bacteria,to aid in traceability analysis of food-borne disease outbreaks,as well as clinical diagnosis and treatment.The pathogenic bacteria in this food poisoning case were i-solated and identified according to GB789.4-2016.The isolated strains were subjected to genotyping with pulsed field gel elec-trophoresis(PFGE).Drug resistance gene analysis,multi-locus sequence typing(MLST),and genome-wide single-nucleotide polymorphism analysis(wgSNP)were conducted via whole genome sequencing(WGS).The evolutionary tree for cluster analy-sis was constructed in fasttree software.Drug susceptibility testing was conducted with the broth microdilution method.A total of 12 strains of Salmonella were detected in seven anal swab samples and two fecal samples from the case,as well as three anal swab samples from unaffected individuals.The serotype of the strains was Salmonella typhimurium.The strain exhibited severe multiple drug resistance,including resistance to amikacin,ampi-cillin,cefazolin,gentamicin,piperacillin,and tetracycline,but susceptibility to other antibiotics.The coincidence rate between drug resistance genes and drug resistance phenotypes was high.PFGE revealed that nine strains from this food poisoning case were highly homologous.WGS revealed that the MLST type was ST19,and varying numbers of SNPs(1-6)were present a-mong strains.The phylogenetic tree revealed nine isolated strains forming a distinct cluster,differing from other Salmonella strains in the database and belonging to a novel clonal branch.The single nucleotide site in the strains was highly homologous to that of GCF in Jiangxi_020221795.1.The food poisoning case was caused by Salmonella typhimurium ST19,and all nine iso-lated strains originated from the same source.The chef is closely connected to this food poisoning case.This strain of Salmo-nella typhimurium belongs to a new clonal branch and exhibits multiple drug resistance.

Objective To observe the expression and distribution characteristics of human orthology of mammalian enabled (hMena) in human glioma, and analyze the correlation of its expression with the pathological grade of the glioma. Methods Sixty-five specimens of glioma with different pathological grades were collected; among these samples, according to the WHO classification, grade Ⅰ was noted in 9, grade Ⅱ in 16, grade Ⅲ in 19 and grade Ⅳ in 21; in 6 of these patients with grade Ⅳ glioblastoma multiforme, tissues from the lesion, the junctional zone between the glioma and the normal brain tissue, and the surrounding area (with a diameter of 1.5 cm) were separated under the assistance of neuronavigation system. Another 5 normal brain tissues from patients with cerebral hemorrhage performed decompression were chosen as controls. Immunohistochemistry and Western blotting were used to detect the expression and distribution characteristics of hMena. Results The hMena expression was negative in control brain tissue, and its positive rates of gliomas with different grades were 11.11% (1/9), 25% (4/16), 84.21% (16/19) and 90.48% (19/21) in gliomas of grade Ⅰ, grade Ⅱ, grade Ⅲ and grade Ⅳ, respectively; and these staining was mainly located in cytoplasm; the hMena expression in gliomas with different grades was significantly different (x2=34.935, P=0.000). The expression rate of hMena was positively correlated with the increasing grade of WHO classification (rs=0.682, P=0.000).Western blotting indicated that, in gliomas with different pathological grades, hMena expression levels increased gradually with the increase of pathological grade. Conclusion The hMena protein might play a role in the malignant progression of glioma.

Objective To establish a molecular genetic analysis method applicable clinically for genetic diagnosis of patients with neurofibromatosis type Ⅱ (NF2) and their offsprings, and further guide the genetic counseling of NF2 family, condition monitoring, follow-up as well as clinical intervention of the patients. Methods Ten patients with NF2, admitted to our hospital from January 2009 to January 2010, were chosen;tumorigenic Schwann cells in Schwannoma were isolated and purified for primary culture. Genomic DNA was extracted from tumorigenic Schwann cells and from the blood of 2 patients and their offsprings who agreed to accept gene sequencing;the NF2 gene was sequenced (El-15 and El7 exons and adjacent introns). According to the implication of NF2 gene sequencing, genetic counseling was given to the NF2 family, and the potential NF2 patients in offsprings were followed up in a long-term. Results Schwannoma tissue and genomic DNA bank were established initially. Totallysame NF2 gene mutations were detected in genomic DNA extracted both from tumorigenic Schwann cells and blood cells in the same patient. By comparing the genotypes between the patients and the offsprings,consistent NF2 gene mutations were found between a female patient and her daughter aged 3, but not completely consistent gene mutations between another female patient and her son aged 15. All of the mutations in NF2 gene were located in the control region near the exons. Based on the patient's clinical manifestations and symptoms, reasonable plans for clinical interventions and follow-up were developed.Conclusion Schwannoma tissue and genomic DNA bank could supply the bio-resource for genetic molecular testing and treatment studies. Molecular genetic analysis would apply in clinical practice guidance, NF2 risk prediction, and follow-up plan for high-risk NF2 individuals. Early diagnosis and treatment, condition monitoring and long term follow-up and personalized clinical intervention are needed to improve the quality of life and prolong the survival.

OBJECTIVETo explore the molecular mechanism underlying the biological function of lncRNA PTENP1 in bladder cancer.

METHODSExpressions of PTENP1, PTEN and miR-17 were examined by quantitative reverse transcriptase PCR (qRT-PCR) in 12 bladder cancer tissues. The expression of PTEN was examined by Western blotting in bladder cancer cell lines T24 and 5637 overexpressing PTENP1. Luciferase reporter assay was performed to confirm the targeting of miR-17 to PTENP1 and PTEN. T24 and 5637 cell lines with stable overexpression of PTENP1 and mir-17 were used to investigate effect of PTNE and miR-17 on the function of PTENP1 in bladder cancer.

RESULTSThe expression of miR-17 was up-regulated and PTENP1 and PTEN were down-regulated in bladder cancer tissues, where a positive correlation was found between PTENP1 and PTEN expressions and a negative correlation between PTENP1 and miR-17 (P<0.05). Overexpression of PTENP1 in bladder cancer cell lines T24 and 5637 obviously enhanced the expression of PTEN protein. miR-17 was found to target both PTENP1 and PTEN and promote the growth of bladder cancer. miR-17 could partially restore the tumor-suppressing activity of PTENP1 in bladder cancer.

CONCLUSIONBy binding with miR-17, lncRNA PTENP1 functions as a PTEN competing endogenous RNA (ceRNA) to suppress the progression of bladder cancer.

Objective To systematically review the safety and efficacy of enhanced recovery after surgery (ERAS) in perioperative management of pancreaticoduodenectomy.Methods A search was performed in databases (including PubMed,EMASE,Cochrane library,Sinomed,Wangfang,VIP,and CNKI) for randomized controlled trials (RCTs) and non-randomized controlled trials (NRCTs) up to September 2016 on use of ERAS in patients undergoing pancreaticoduodenectomy.After quality evaluation and data extraction,meta-analysis was performed using RevMan 5.3.Results Four RCTs and Twelve NRCTs involving a total of 2 828 patients were included.1 401 patients were in the ERAS group,and 1 427 in the control group.Meta-analysis results showed that compared with the control group,the ERAS group had shorter length of hospital stay (SMD =-0.36,95 ％ CI =-0.44--0.28,P＜ 0.05) and lower incidence of delayed gastric emptying (RR =0.61,95％ CI=0.51-0.73,P＜0.05).However,no significant differences were observed in pancreatic fistula rate,bile fistula rate,readmission rate,reoperation rate,and overall mortality morbidity rate between the two groups (all P＞0.05).Conclusion It is reasonably safe and efficacious to adopt ERAS in periopetative management of patients undergoing pancreaticoduodenectomy.
