Hereditary multiple exostoses (HME) is an autosomal dominant genetic disease characterized by multiple benign cartilage-capped tumors primarily at the juxta-epiphyseal region of the long bone or on the lfat bones. Because the tumor can interfere with normal epiphysis, it causes bone deformities. The clinical features include short stature, the mechanical axis deviation, and function impairment. Recent studies showed that EXT gene mutation was associated with HEM. The EXT gene was involved in the biosynthesis of heparin sulfate. The gene mutations resulted in abnormal chondrocyte differentiation. This paper reviews the research progress in clinical manifestation, pathogenesis, biochemistry, the genotype-phenotype correlations, and treatment in HME.

Objective:To explore the effect of management mode of correspondence of potencyscale on impro-ving the nurses′job satisfaction and patient satisfaction in the department of neurology and analyze the medical eth-ics. Methods:We selected 37 nurses in the department of neurology. From July 2013 to March 2014, they were provided with the traditional management mode, whereas from March 2014 to June 2015 with management mode of correspondence of potencyscale. The questionnaire survey was conducted to measure the job satisfaction of nurses and the satisfaction degree of patients. Results:After the implementation of management mode of correspondence of potencyscale, the research indexes were significantly higher than before. Conclusion:The management mode of correspondence of potencyscale can improve the nursing staff′s work enthusiasm, patient satisfaction, and the quali-ty of care. Meanwhile, it is the specific practice of nursing ethics.

Objective To evaluate the short-term efficacy of the use of Y-shaped mesh in the treatment of anterior vaginal wall cystocele and stress urinary incontinence. Methods A total of 34 women diagnosed as having anterior vaginal wall cystocele complicated with stress urinary incontinence underwent intravaginal slingplasty using a Y-shaped mesh from April 2003 to May 2006. Evaluations on symptom improvement and postoperative recurrence rate were made. Results All the patients could spontaneously void urine after catheter removal at 24 hours after operation, with the residual urine less than 100 ml. Follow-up checkups for 3~37 months (mean, 26 months) found no urinary retention, urinary tract infection, bladder dysfunction, or recurrence. Conclusions Use of Y-shaped mesh in the treatment of both anterior vaginal wall cystocele and strees urinary incontinence is feasible.

Mesenchymal stem cells (MSCs) not only exhibit a marked tropism for tumors,but also exert antitumorigenic activity or as an emerging vectors to express foreign genes continuously and efficiently within the tumor microenvironment,suppress tumor's growth and metastasis.Conversely,MSCs can accelerate tumor development through promoting tumor stroma remodeling and tumor vascular formation,inhibiting tumor local immune and changing tumor phenotype.The reason for this discrepancy may be attributable to different sources of MSCs,the heterogeneity of MSCs,differences in tumor microenviroment,or another factor that is not yet appreciated.

Purpose To exp1ore the expression and c1inica1 significance of epiderma1 growth factor receptor( EGFR)and human epi-derma1 receptor-2(HER-2)in co1orecta1 carcinoma. Methods Immunohistochemistry(IHC)PV-9000 was used to detect the expres-sion of EGFR and HER-2 in 78 cases of co1orecta1 carcinoma. Si1ver in situ hybridization( SISH)was used to detect HER-2 amp1ifica-tion in co1orecta1 carcinoma. Results The positive rates of EGFR in 78 co1orecta1 carcinomas were 69. 23%( 54/78 ). The differ-ences of the expression of EGFR between different depth of invasion group and 1ymph node metastasis group were statistica11y signifi-cant. The differences of the expression of EGFR between different aging group,gender group,tumor size,different histo1ogica1 grading group and Dukes stage were insignificant. The positive rates of HER-2 in 78 cases of co1orecta1 carcinoma were 25. 64%(20/78). The differences of the expression of HER-2 between different depth of invasion group and 1ymph node metastasis group were statistica11y sig-nificant. The differences of the expression of HER-2 between different aging group,gender group,tumor size,histo1ogica1 grading group and Dukes stage were insignificant. The expression of EGFR and HER-2 was positive1y corre1ated. Among the 20 cases of HER-2 protein overexpression,10 cases showed HER-2 gene amp1ification,15 cases showed HER-2 protein overexpression(~)by IHC and 10 cases showed HER-2 gene amp1ification by SISH. The rate of HER-2 gene amp1ification was 66. 67%. 5 cases with 1ow HER-2 protein overexpression( +)and no case showed HER-2 gene amp1ification. Conclusions EGFR and HER-2 are high1y ex-pressed in co1orecta1 carcinoma. EGFR and HER-2 expression is connected to invasion and metastasis process of co1orecta1 carcinoma. The both may be synergy. The corre1ation between HER-2 protein overexpression(~)and HER-2 gene amp1ification is statisti-ca11y significant. Therefore,immunohistochemistry can be regarded as an initia1 screening method for HER-2 gene amp1ification,and then SISH testing shou1d be done as we11 to confirm the resu1t. It is usefu1 for mo1ecu1ar target therapy to detect HER-2 status in co1or-ecta1 carcinoma.

Objective To investigate the clinical manifestations of the febrile neutropenia cancer children,explore the relationship between the clinical data and sepsis.Methods A prospective observation study was employed,and 66 cancer children complicated with febrile and neutropenia after chemotherapy were enrolled.Sixty-six cases were divided into two groups:septic group ( n =26 ) and non-septic group ( n =40).Clinical and laboratory data were collected and compared.Results Body temperature,neutropenia duration,absolute neutrophic count ( ANC ),C-reactive protein ( CRP ),procalcitonin (PCT) and culture positive rate showed statistically differences between the septic and non-septic groups ( P ＜ 0.05 ).Body temperature ＞40 ℃,ANC ＜ 0.1 × 109/L,increases of serum CRP and PCT levels and positive culture were correlated with sepsis.Body temperature ＜ 39 ℃,neutropenia duration ＜ 5 ds,ANC ＞ 0.5 × 109/L were less correlated with sepsis.Conclusion High initial temperature,long duration of neutropenia,severely reduced ANC,increases of CRP and PCT,and culture-positive are correlated with sepsis in cancer children.

ObjectiveTo explore the distribution and characteristics of health risk behaviors between the male and female college freshmen in the medicine and science,and to provide evidence for appropriate health intervention measures.MethodsA questionnaire investigation was performed on college students'health risk behaviors among 1019 freshmen from medical and science college in urban area of Harbin.Results (1)There were statistically significant among the different gender in difference of risky behaviors except playing video games,net surfing,considered suicide,drug abuse and a few activities outside the 60 minutes every day (P ＜ 0.01 ).(2)Medical male risk behavior of the frequency(56.4％,19.2％,12.7％ and 47.1％ )higher than that of science and engineering male(35.6％,5.2％,1.6％ and 17.3％ )in trying to smoking,current smoking,sexual behavior and breakfast skipping.Recent medical males drinking rate was 85.3％ higher than male of science and engineering 72.2％.The incidence of female science and engineering students,respectively( 89.3％,50.8％ and 38.5％ ) than female medical students (72.4％,36.9％ and 8.0％ ) in trying to drinking and recent drinking and breakfast skipping.ConclusionThe risk behaviors of college freshmen were prevalent.The frequency of risk behaviors are different among the College Freshmen in different genders and with different major,respectively.Therefore,it is necessary to take measures for intervention.

Objective To analyze the pregnancy outcomes and effect on fertility in women with Graves' disease after 131I therapy and the health status of their newborns.Methods From year 2009 to 2012,a total of 102 female patients with Graves' disease,who were pregnant during propylthiouracil (PTU)/L-thyroxine (euthyrox) maintenance treatment,were retrospectively recruited.The subjects were divided into 131I therapy group (n=57) and non-131I therapy group (n=45).The time interval between 131I (non-131I) therapy and getting pregnant were at least 6 months.They were followed for their pregnancy outcomes.During the pregnancy period,recorded parameters included serum thyroid biochemistry,dose of PTU/euthyrox,health conditions of the newborns and termination of pregnancy.Medication compliance,delivery mode,baby gender and body weight between the 2 groups were compared byx2 test,Mann-Whitney u test,Fisher exact test and two-sample t test.Results Ninety-seven patients had normal labor.In 131I therapy group and non-131I therapy group,15 vs 22 patients were treated by PTU,31 vs 18 by euthyrox and 11 vs 5 without any medication during pregnancy (x2=5.69,P＞0.05).The medical compliance (PTU and euthyrox: u=163.50,233.50,both P＞0.05) was similar between the 2 groups.The delivery mode (natural labor/cesarean: 36/19 vs 28/14,x2 =0.016),baby gender (male/female: 32/23 vs 18/24,x2 =2.239) and body weight ((3.18t0.47) vs (3.07±4.17) kg,t=1.154) were also similar between the 2 groups (all P＞0.05).Condusion Women of reproductive age with Graves' disease were found to have normal pregnancy after 131I therapy,on the condition that their thyroid function could be reasonably controlled and maintained by the proper medication before and during pregnancy.
