Objective To investigate the significance of DNA ploidy analysis in diagnosis of atypical squamous cell of undetermined significance ( ASCUS).Methods From Jan.2009 to Jul.2011,875 women with ASCUS confirmed by liquid based thin layer cytology technique underwent DNA ploid analysis in Hubei Maternal and Child Health Hospital.Among 294 women underwent high risk HPV detection.All subjective were examined colposcopy directed biopsy at day 3 to 10 after menstruation.Results Among 875 ASCUS cases,553 cases with histologically as chronic cervicitis (63.2％),165 cases with cervical intraepithelial neoplasia (CIN) Ⅰ (18.9％ ),45 cases with CIN Ⅱ (5.1％),79 cases with CIN Ⅲ (9.0％) and 33 cases with cervical invasive cancer (3.8％) were confirmed by colposcopy.Totally 532 cases were observed with DNA heteroploid,and 343 were not observed with DNA heteroploid.When DNA heteroploid negative and more than or equal to three ploid were used to predict CIN Ⅱ or more severe cervical diseases,the sensitivity,specificity,positive predictive values and negative predictive values were 98.7％ and 90.3％,47.5％ and 46.1％,29.1％ and 40.8％,99.4％ and 92.1％,respectively.The amount of heteroploid cells ＞2.5c and ＞ 5c among every 100 detected cells in chronic cervicitis and CIN Ⅰ,CIN Ⅱ,CIN Ⅲ and cervix cancer were respectively 2.53 ± 1.99 and 0.10 ±0.07,2.24 ± 1.69 and 0.20 ±0.11,4.10 ± 1.91 and 0.28 ±0.19,7.97 ±7.33 and 1.27 ± 1.23,8.99 ±7.33 and 0.36 ±0.33,there was no statistical difference in amount of heteropolid cells between ＞ 2.5c and ＞ 5c at group of chronic cervicitis and CIN Ⅰ,CIN Ⅲ and cervix cancer (P ＞ 0.05).However,the amount of heteroploid cells at ＞2.5c and＞ 5c at group of chronic cervicitis,CINⅠ,CIN Ⅲ and cervical were higher than that of CIN Ⅱ significantly (P ＜0.05).Among 294 cases with high risk (HR) HPV detection,216 cases were HR-HPV positive,and 78 cases were HR-HPV negative.The pathology result by colposcopy at group of negative heteroploid,heteroploid ＜ 3,or ≥ 3 showed statistical distribution (x2 =115.2775,P ＜ 0.01).ConclusionDNA ploidy analysis can be used for ASCUS diagnosis,which can avoid excessive biopsy under colposcopy,in the mean time,CIN and cervical cancer could decrease missed diagnosis.

OBJECTIVE:To test the static balance function of boys aged from 6 to 8 years and then to establish a system of evaluating the static balance function.METHODS:A total of 388 boys aged from 6 to 8 years were randomly selected from 16 kindergartens of 8 counties(cities)in 4regions of Hebei Province.The inclusive cdteria were as follows:no systematic training of sports,no myopia,normal body shape and no obvious obesity.The balance force-measuring plates made by Hefei Institute of Intelligent of Chinese Academy of Sciences,computer and the supporting software were adopted.The subjects received an indoor test of 6 testing postures,namely,standing on two feet with eyes open(and closed),standing on left leg with eyes open(and closed),standing on right leg with eyes open(and closed).Six indexes relating to balance abilities including the mean of X direction,the mean of Y direction,R value,track length per unit time and track location variance of the envelop area.RESULTS:The original screening of all indexes showed that 6 kinds of postures reduced to 4 and that indexes reduced from 36 to 24.The second screening with cluster analysis which was conducted to the 4 kinds of postures showed that 24 indexes reduced to 17 when selecting typical indexes from each cluster.The third screening with factor analysis showed that 7 out of the 17 indexes were remained.Seven representative indexes corresponding to these 7 factors were concluded and considered as the comprehensive evaluation indexes of the static balance.The comprehensive static balance evaluation index systems for 6-year-old.7-year-old and 8-year-old boys were established respectively.CONCLUSION:Three systems for evaluating the static balance function of the boys aged from 6 to 8 years are established successfully based on 7 indexes.The evaluation of static balance function should be based on the comprehensive evaluation of multiple indexes.The evaluation indexes for 6-year-old,7-year-old and 8-year-old boys are identical in number,but different in content.Accordingly,a specific evaluation index system should be established for them separately.

Early lymph node metastasis is a common clinical phenomenon in many human cancers, which is associated with both aggressive disease and poor prognosis. Clearly, treatments to specifically block dissemination through the lymphatic network would be desirable either as independent therapies or as adjuncts to existing chemotherapy. At the present stage the target vessels for invasion by lymph-metastasizing tumor cells include preexisting tissue lymphatics abutting the tumor mass through either coincidence or mutual chemoattraction, as well as new lymphatic vessels that proliferate either within or around the tumor as a result of lymphangiogenesis. The lymphangiogenesis is regulated primarily by the lymphangiogenic growth factors VEGF-C and VEGF-D generated by tumor cells or host cells including tissue macrophages. Nevertheless, it remains controversial as to whether this metastasis-enhancing effect simply results from an increase of the number of target vessels due to mitogenesis or from other properties of the newly dividing tumor lymphatics.

Objective To explore ways of enhancing the therapeutic level of the neurology department and reducing the economic burdens of patients. Methods Relevant materials were collected by means of evidence based medicine to optimize therapeutic schedules, with cerebral infarction being the pitching in point. Results Prior to the adoption of evidence based medicine, the average length of stay, the effective rate of treatment and the expenses for single entity diseases were respectively 17.83?13.44, 89.91% and 4 550.70 yuan, whereas after the adoption of evidence based medicine, they were respectively 15.38?11.37, 94.16% and 3 942.88 yuan. Conclusion Evidence based management is a means of scientific management. Its application in the department of neurology has produced a marked effect and it is worthy to be spread.

Objective To analyze the factors contributing to local recurrence following body gamma knife radiotherapy in patients with non-small cell lung cancer(NSCLC),and to explore a standard therapeutic scheme under the circumstance.Methods 332 patients with NSCLC received body gamma knife therapy and subsequent regular follow-up.Dose per fraction and total dosage used were dependent on disease condition,tumor location,tumor features and tumor size,etc.On the basis of patients' conditions and adverse effects,biological effective dose(BED) was 56-90Gy calculated with LQ model.Univariate analyses were performed including sex,age,Karnofsky performance score,clinical stage,pathological type,tumor differentiation degree,tumor size,tumor location,target volume delineation,dose per fraction,BED and chemotherapy scheme,etc.with X2 or t test.By selecting significant clinical factors in univariate analysis,multivariate analyses were performed with COX regression model.Results Of the 332 patients,local recurrence occurred in 22 cases during regular follow-up period,with average recurrence time of 10 months,and the local recurrence rate was 6.63%.The results of multivariate analysis showed that low BED,low Karnofsky score,old age,too small delineation for target volume range and central type of lung cancer were the factors related to local recurrence.Conclusions Low BED in body gamma knife radiotherapy is the significant factor of local recurrence for patients with NSCLC.BED in body gamma knife radiotherapy should be more than 80Gy for NSCLC patients who receive the radical treatment.

Objective To explore the preoperative assessment of airway morphology affecting the early-phase prognosis by observing congenital tracheal stenosis survival after surgical treatment.Methods Totally 52 cases of CTS surgically treated in the Shanghai children's Medical Center,from April 2007 to June 2013,were retrospectively analyzed to study their clinical characteristics,survival condition and related factors influencing the early-phase prognosis.Using log-rank test and Cox multiple factors analysis for statistical analysis.Results Overall postoperative survival rate of 3 months was 73.1％.There were 14 deaths among 48 patients.Single factor and multiple factors analysis showed that the cross-sectional area(CSA) of stenosis and Anton-Pacheco classification were both associated with early-phase prognosis as independent factors(P ＜0.05).Long CPB duration was a prognostic factor for the outcome of surgical treatment for CTS(P ＜ 0.05).CPB time was significantly longer in death cases than in surviving cases.Conclusion CSA and Anton-Pacheco classification were significant prognostic factors for CTS.The proper utilization of radiologic imaging allow for improved patient care.

Objective To explore the relationship between sperm DNA fragmentation rates and male infertil-ity.Methods Case -control study was used .Sperm DNA fragmentation rates were compared between the primary infertile males for unknown reasons (n=126) and the males whose spouses undergoing delivery in three months (n=100).Results Sperm DNA fragmentation rate of the research group was (11.95 ±4.89) %.Sperm DNA fragmenta-tion rate of the control group was (10.07 ±3.56) %.Significant difference was found between the two groups on sperm DNA fragmentation rate(t=-3.326,P=0.001).The 226 men were divided into group A with sperm DNA fragmentation rates<10%(n=130) and group B with sperm DNA fragmentation rates≥10%(n=96).The percent-age of male infertility in group A was significantly lower than that in group B (50.00%vs 61.62%) (χ2 =4.105, P=0.043).Conclusion Correlation is found between sperm DNA fragmentation rates and male infertility .

Objective To observe the effect of irbesartan on the expression of angiopoietinlike protein 2 (ANGPTL2) in the diabetic rats kidney and explore the underlying mechanism.Methods A total of sixty male SD rats were divided into normal control group (NC group,n=15) and experimental group (n=45) randomly.The experimental group was fed with high sugar-fat diet and given a low dose streptozocin (STZ 30 mg/kg)to establish type 2 diabetic model.Rats successfully induced diabetes were randomly divided into 2 groups:diabetes group (DM) and irbesartan group (DI).Weight,blood pressure,blood glucose,serum creatinine (Scr),blood urea nitrogen(BUN),24 hour urinary albumin(UAL) and renal histomorphology were observed after drug intervention at the 4th,8th and 12thweeks.The expression of ANGPTL2 in renal tissue were detected by immunohistochemistry,real-time PCR and Western blotting.Results The levels of Scr,BUN,TG,TC and UAL in group DM were higher than in group NC at the 4th,8th and 12th week (all P ＜ 0.05).Compared with that in group DM,above indexes were lower in group DI at the 4th,8th and 12th week (all P ＜ 0.05).The pathological changes of the kidney in group DM were more serious than that in group DI.The expression of ANGPTL2 in group DM was much higher than that in group NC at the 4th,8th and 12th week (all P ＜0.05),and irbesartan treatment inhibited the up-regulation of ANGPTL2 in group DI(all P ＜ 0.05).Conclusion The expression of ANGPTL2 increases in T2DM rats kidney tissue with time and irbesartan can inhibit the up-regulation of ANGPTL2 in T2DM rats.
