Objective:To examine the correlation between the self-worth and mental health of middle school students .Methods:The Scale of Self-worth for Young Students and the SCL-90 were admemestered to a sample of 699 middle school students.Results:Analysis showed significant negative correlation between self-worth and the SCL-90 and mental health of middle school students,the SCL-90 scores of students with high self-worth were significantly different from that of students with low self-worth.Conclusion:The higher the self-worth of middle school students is ,the better their mental health is.

Objective To investigate the obstructive sleep apnea syndrome ( OSAHS) associated with nasal resistance.Methods 30 cases with obstructive sleep apneahypopnea syndrome ( OSAHS ) in the OSAHS group, 30 cases with snoring but without OSAHS in the snoring group and 30 cases with normal group based on polysomnog-raphy were detected the nasal resistance.Results The index of thsnoring index[(42.7 ±27.3),(19.4 ±18.5), AHI(38.7 ±30.2),(5.9 ±1.6)and Resl+r(1.63 ±1.11)Pa· s-1· mL-1,(0.72 ±0.31)Pa· s-1· mL-1] in OSAS group and snoring group were significantly higher than those of the normal group ( t=6.451,7.444,7.698,all P<0.05);The index of lowest oxygen saturation ( SaO2 ) ,Flowl+r in OSAS group and thsnoring group were lower than that in normal group(t=7.551,7.334,all P<0.05);There were significant differences among groups of nasal resistance (t=7.451,8.144,8.608,8.904,all P<0.05);There were positive correlation between nasal resistance and snore index (r=5.658,P<0.01);The index of nasal resistance correlated with AHI index (r=0.002,P>0.05),wake times (r=0.083,P>0.05) and lowest SaO2(r=0.105,P>0.05)were not significantly correlated;The cases with OSAS cephalometric.The results suggest majority snoring symptoms significantly more at supine posi-tion in OSAS.Conclusion Nasal resistance increased,which may be associated with the occurrence in patients with OSAHS.

Objective To evaluate the effect of refractive correction on the dynamic variation of diopter in children with hyperopia ametropic amblyopia. Methods Optometry with 1 % atropine oculentum was used to examine 105 patients(210 eyes) with ametropic amblyopia aged 3～6 years old. The diopter of all the cases was compound hyperopic astigmatism. The prescriptions of spectacles were made according to that the diopter of retinoscopy subtracted different degree hyperopia. Thus,all the patients were divided into group 1(subtract 20% off the diopter of retinoscopy,30 cases),group 2(subtract 25% off the diopter of retinoscopy,40 cases),group 3(subtract 30% off the diopter of retinoscopy,35 cases). During three years' treating periods, their dynamic variation of hyperopia diopter were observed time yearly. Results The hyperopia diopter of each group reduced year after year. But the average reduction of hyperopia diopter of group was significantly lower than that of other two groups(P0.05).Conclusion Refractive corrections of different degree have effect on emmetropization of children with hyperopia ametropic amblyopia. Moderate undercorrection is useful on emmetropization of children with hyperopic ametropic amblyopia.

Objective To establish a calcification mode in vitro of human vascular smooth muscle cells (HVSMCs) induced by β-GP. Methods Primary HVSMCs were obtained from human embryo by plant method and confirmed by stain with α-sm-actin antibody. The cells after 4-6 passages were divided into two groups.The control group was incubated with normal DMEM medium while the calcification group was incubated with the medium containing 10 mmol/L β-glycerophosphate for 10 days.Calcification was confirmed by alizarin red S stain and alkaline phosphatase(ALP) assays. Results The primary cells observed by S-P stain were positive and the cells after being stained were pale yellow. After being induced with β-GP, the cells of calcification group began concentric growth and formed vesicles. Alizarin red S staining showed that the reaction of calcifying nodules was red,ALP activity was higher than that of controls at various time points(4 d,6 d,8 d and 10 d,P＜0.01 ).Conclusion The HVSMCs could be induced into calcification in vitro by β-GP, and this model contribates to further studies of vascular diseases.

In the present study, the efficacy of Naoxintong capsule (NXT), a compound Chinese herbal medicine, combined with dual antiplatelet therapy (DA) in a rat model of coronary microembolization (CME) was evaluated.

Objective To study the technique and clinical effect of endoscopic surgery using high frequency electrotome with suction device for nasopharyngeal angiofibroma. Methods In this study, we retrospective analyzed the clinical data of 10 patients treated between January 2009 and December 2015. All these patients were treated by endoscopic surgery using high frequency electrotome with suction device. The average blood loss during surgery, tumor residual, recurrent tumor and duration of recovery were evaluated. Results The tumor was completely removed in all 10 patients. The average blood loss was 465 ml, there was no postoperative complication, all patients had no residual tumor, and there was no recurrent tumor over a follow-up of 6~18 months. Conclusion Though it was not preoperative transcatheter arterial embolization, the endoscopic surgery using high frequency electrotome with suction device can be used to treated nasopharyngeal angiofibroma which either limited to nasopharyngeal cavities and paranasal sinus with intraoperative blood pressure control.

In view of risk characteristics of surgical site infection,the risk factors of the infection were graded and classified while the risk indicators system and risk assessment matrix for surgical site infection were built,based on literature analysis,integrated use of documents analysis,Delphi method and risk quantification matrix.The study indicated that surgical skills of the surgeon and surgical time length are the most important risk factors,followed by insufficient maintenance of the operating room environment and poor baseline assessment of the patient.Risk control of surgical site infection needs to focus on these key factors,optimize utilization of resources and improve the prevention and control ability of surgical site infection.

Objective To study the application value of serum umbilical cord blood bilirubin and hemolysis three test in the prediction of neonatal hyperbilirubinemia.Methods 1 200 cases of healthy newborn were selected,whose mothers were type O blood and fathers were not type O blood.According to the situation of maternal and infant blood type,they were divided into the same maternal and child blood type group with 539 cases and different blood type group with 661 cases;According to the umbilical cord blood bilirubin concentration range was divided into five groups,and analyzed umbilical cord blood bilirubin and hemolysis three test in the prediction of neonatal hyperbilirubinemia.Results (1) The concentrations of umbilical cord blood bilirubin,the incidence of ABO-HDN,the incidence of hyperbilirubinemia in the maternal-fetal blood(O-A/B) group were (38.1 ± 10.3) μmol/L,47.35％,26.02％,respectively,which were all significantly higher than (33.4 ± 7.9)μmol/L,15.21％,14.66％ in the maternal blood type (O-O) group (t =5.8,x2 =120.7,x2 =20.1,all P =0.000) ; (2) When the concentrations of umbilical cord blood bilirubin was higher,the incidence of hyperbilirubinemia was higher,but the sensitivity and the specificity both were bad; (3) According to the result of hemolysis three to predict the neonatal hyperbilirubinemia,when the concentrations of umbilical cord blood bilirubin was less than 21μmol/L or more than 55μmol/L,the positive predictive value and the specificity both were 100.00％,and the sensitivity was not low(75.00％ and 86.96％).Conclusion Detection of umbilical cord blood bilirubin and hemolysis three test in the maternal-fetal blood group incompatibility could predict early hyperbilirubinemia of newborn,which had certain clinically practical value.
