Objective To explore the relationship between responsibility and social adaptation of the left-behind middle school students and to provide evidence for mental health education of left-behind children.Methods 290 left-behind middle school students were selected by cluster-random-sampling.All of them were assessed by the middle school students' social adaptability scale (SAS-SSS),the inventory of parent and peer attachment (IPPA) and the scale of high school students' responsibility.Results The correlation between responsibility,attachment behavior and social adaptation of left-behind middle school students were significant(r=0.39,r=0.56,P＜0.01).There were significant differences between gender on the responsibility(male(202.64±26.78) vs female(212.67±23.24)).Regression analysis showed that mother attachment,overall responsibility,general responsibility and special fault responsibility could predict the social adaptation(P＜0.05).Responsibility and its factors played a mediating role between attachment and adaptation,taking 52.1％,20.1％,30.8％,9.1％,47.9％,40.7％ proportion of the total effect.Conclusion Responsibility is an important factor affecting the social adaptation of left-behind middle school students.

AIM:To explore the distance from the labrale superius and inferius of the soft tissue profile in early permanent dentition with normal occlusion to the esthetic line (E line) and the proportion among each section of E plane. METHODS: Thirty Han teenagers with normal occlusion including 15 males and 15 females with the average age of 11.5 years were selected from January 2000 to December 2005. They were examined cephalometrially to measure the distance between labrale superius (Ls) and E, labrale inferius (Li) and E, and the mean values and standard deviation of prenasale (Prn)-Ls/distance between Prn and pogonion (Pg') of soft tissue, Ls-Li/distance between Prn and Pg' and Li-Pg'/distance between Prn and Pg'. RESULTS: ①Distance of Ls-E and Li-E: Ls-E and Li-E of normal occlusion were (0.083 3?0.920 8) mm and (0.621 7?1.124 6) mm. ②Proportion of each segment to the distance of Prn and Pg': Prn-Ls/Prn-Pg', Ls-Li/Prn-Pg' and Li-Pg'/Prn-Pg' were 0.413 8?0.022 3, 0.200 9?0.023 1, 0.385 7?0.022 8, respectively. CONCLUSION: E plane analysis is a convenient and effective method in the diagnosis of soft tissue in clinic. The Ls and Li are exactly on the E plane in normal occlusion and the ratio of three sections is 2∶1∶2.

BACKGROUND: Oxidation injury can lead to the apoptosis of lens epithelial cells. Some researches have found that body supplement of vitamin C is beneficial to inhibit oxidation injury by increasing the level of vitamin C in aqueous humor.OBJECTIVE: To observe the inhibitive effect of vitamin C on H2O2 induced apoptosis of lens epithelial cell.DESIGN: Randomized controlled trial taking animal's lens as subject.SETTING: Department of Ophthalmology, Medical College of Qingdao University.MATERIALS: 120 adult New Zealand rabbits of both genders, weighing 3-5 kg, were selected. Vitamin C and 300 g/L H2O2 were purchased from Shanghai Guangda Chemical Reagent Factory.METHODS: The experiment was carried out in the Central Laboratory, the Affiliated Hospital of Medical College of Qingdao University from January 2002 to January 2004. ①Culture of lens: 240 lenses were isolat ed from 120 rabbits after being killed. Among them, 192 clear lenses were selected and divided randomly to three groups with 64 lenses in each group: control group, H2O2 group and H2O2+vitamin C group. Lenses in the control group were incubated in non-serum and non- phenolsulfonphthalein MEM medium, those in the H2O2 group incubated in non serum and non- phenolsulfonphthalein MEM medium containing 1 mmol/L H2O2 (62 μL of 30 g/L H2O2 was added into the medium every 6 hours to keep H2O2 level maintain 1 mmol/L in the medium), and those in the H2O2+vitamin C group incubated in non-serum and non- phenolsulfonphthalein MEM medium containing 1 mmol/L H2O2 and 1 mmol/L vitamin C. Under the same culture condition, the lenses in each group were detected at hours 6, 12, 18, 24, 36, 48, 72 and 108 after culture, respectively. ②Measurement of the opacity of lens: Under the white background, two black lines 0.5 mm in width, which were mutually vertical with an interval of 10 mm. The lenses were placed above the crossing to measure the opacity. ③Detecting the apoptosis of lens epithelial cells:The apoptosis of lens epithelial cells was examined using TUNEL method and DNA fragmentation assay under light microscope to calculate the apoptotic rate of epithelial cells.MAIN OUTCOME MEASURES: ①Opacity of the lenses in each group;②apoptotic rate of lens epithelial cells in each group.RESULTS: ①After 108 hours of culture, the opacity of the lenses in the H2O2+vitamin C group was obviously lower than that in the H2O2 group. ②The apoptotic rates in the control group were lower that those in the H2O2group at different time point and those in the H2O2+vitamin C groupat hours 24, 48 and 72 after culture(P＜0.05-0.01). The apoptotic rates in the H2O2+vitamin C group were significantly lower than those in the H2O2group at different time points after culture (P＜0.01). ③The findings of DNA fragment analysis showed that the DNA "ladder" was found in the H2O2 group during 24-72 hours, while no DNA "ladder" but only normal electrophoresis strap were present in the other two groups 24 hours after culture.CONCLUSION: Lens can take refuge from the oxidative injury of H2O2with the addition of vitamin C. As a result, the apoptosis rate of lens epithelial cells and further, cataract formation can be restrained.

Objective To describe and analyze the distribution of medical expenditure of Liaoning province in 2014 in terms of population beneficiary based on the System of Health Accounts 2011(SHA 2011).Methods By means of multistage and stratified sampling, a total of 252 medical institutions were selected from four cities in Liaoning province according to their economic status and geographical distribution.Macro data including the outpatient income and hospitalization income were taken into account, to calculate the beneficiary population of the province in 2014 according to SHA2011.Results GBD classification found that the highest medical expenditure category was non-communicable diseases, accounting for 63.02% in total medical expenditure.ICD classification found that respiratory disease as consuming the highest medical expenses (43.76%).The average medical expenditure of the elderly population was the highest per person, up to 3 041.70 yuan per person.Conclusions Medical expenses of non-communicable diseases, respiratory disease and elderly population were still high.Thus we need to emphasize disease prevention, and take efficient measures against such key diseases to curb the medical expenses.The elderly population calls for specific and effective measures to reduce their medical expenses.

To investigate whether the Bcl-2 gene family is involved in modulating mechanism of apoptosis and change of cell cycle protein induced by curcumin in acute myeloid leukemia HL-60 cell line and primary acute myelogenous leukemic cells, the Bcl-2 family member Mcl-1, Bax and Bak and cell cycle proteins including P27kipl, P21wafl, cyclin D3 and pRbp- were selected and their expression detected by SABC immuno-histochemical stain method. The attitude of sub-G1 peak in DNA histogram was determined by FCM. The TUNEL positive cell percentage was identified by terminal deoxynucleotidyl transferase (TdT)-mediated Biotin dUNP end labeling technique. It was found that when HL-60 cells were treated with 25 mumol/L curcumin for 24 h, the expression level of Mcl-1 was down-regulated, but that of Bax and Bak up-regulated time-dependently. There was significant difference in the expression level of Mcl-1, Bax and Bak between the curcumin-treated groups and control group (P < 0.05-0.01). At the same time, curcumin had no effect on progress of cell cycle in primaty acute myelogenous leukemia at newly diagnosis, but could increase the peak of Sub-G1 (P < 0.05), and down-regulate the expression of Mcl-1 and up-regulate the expression of Bax and Bak with the difference being statistically significant. The expression of P27kipl, P21wafl and pRbp- were elevated and that of cyclin D3 decreased in the presence of curcumin. These findings suggested that the Bcl-2 gene family indeed participated in the regulatory process of apoptosis induced by curcumin in HL-60 cells and AML cells. Curcumin can induce apoptosis of primary acute myelogenous leukemic cells and disturb cell cycle progression of HL-60 cells. The mechanism appeared to be mediated by perturbing G0/G1 phases checkpoints which associated with up-regulation of P27kipl, P21wafl and pRbp- expression, and down-regulation of cyclin D3.

Findings of DNA fragmentation assay:The DNA"ladder"was found in the H2O2 group at hours 24,36,48 and 72,while no DNA"ladder"but only normal electrophoresis straps were present in the other two groups 24 hours after culture.CONCLUSION:Taurine can inhibit the oxidative injury-induced apoptosis of rabbit lens epithelial cells,and alleviate lens opacity.

Objective To investigate the imaging features of adrenal rest tumor.Methods Twelve patients of adrenal rest tumor proved by surgery or clinical diagnosis were retrospectively analyzed.Among these 12 patients,12 were examined with ultrasound,11 with MR and 1 with CT. MR and CT were performed without and with intravenous injection of contrast material.The imaging features of adrenal rest tumor were retrospectively summarized and the relevant literatures reviewed. Results The adrenal rest tumors were found in testis in 10 of the 12 patients,and in ovaries and broad ligament in the remaining two.The imaging features of the testicular adrenal rest tumor were summarized as following:all patients had bilateral testicular masses without change of the testicular contour. On ultrasonography,the lesions were hypoechoic, with some hyperechoic areas and appeared highly vascularized on Colour Doppler ultrasonography.The masses showed iso-density on plain CT,and avid enhancement on post-contrast CT images.The masses ranging in size from0.7 cm×1.0 cm×2.2 cm to 2.3 cm ×2.7 cm ×2.9 cm with uniform signal intensity,lobulated margin on MRI.They exhibited iso- or slight hyperintensity on T1 WI and hypointensity on T2WI relative to normal testicular parenchyma.The tumors showed intense enhancement on post-contrast MR images. No abnormality was detected with Colour Doppler uhrasonography and MR in 2 patients of adrenal rest tumor in ovaries and broad ligament. Conclusion Combining imaging features with the typical clinical history,the diagnosis of adrenal rest tumor could be suggested pre-operatively.
