Objective To compare internet addiction disorders' family cohesion and their family educa-tion style, and to help prevent internet addiction disorder and interference treatment in families with internet addic-tion disorder. Methods Ninety adolescents with internet addiction disorder were investigated as the experimental group and one hundred normal adolescents as the control group. Questionnaire and in-depth interview was used to collect data,and the data was analyzed with SPSS 10.0. Results Average scores of control group were significant higher than those of experimental group in family cohesion ((51.75±8.86) vs (38.89±12.17), P<0.01). Av-erage scores of control group were significant higher than these of experimental group in family education style ((50.65±7.66) vs (41.44±10.84), P < 0.01). Average scores of experimental group were significant higher than those of control group in dissatisfaction of family cohesion and family education style ((20.87±4.66) vs (12.33±7.88); (23.30±11.06) vs (14.28±7.29), P < 0.01). Conclusion The adolescents with internet addiction disorder have low family cohesion and high dissatisfaction of family education style,wherefore during in-ternet addiction family intervention and prevention, it should pay particular attention to cultivating close and harmo-nious relations among families members. In aspect of family education, parents should pay special attention to chil-dren's healthy personality development, and guide their children to actively take part in social practice and train-ing.

Objective To compare T2* value in healthy and diseased achilles tendons (AT) using 3D-ultra-short echo time (UTE),and to analyze the correlation between T2* value and clinical scores.Methods Fifteen patients (patients group) and ten volunteers (control group) were included and underwent an MR scan with UTE sequence.The T2* value of four ROI in AT were calculated.Independent sample t-test was used to compare the differences of T2* value between two groups.The correlation of T2* values with the American Orthopaedic Foot and ankle society ankle hindfoot scale (AOFAS) and achilles tendon total rupture score (ATRS) were analyzed.Results The T2* value of four ROI were statistically significantly higher in patients group than those of control group.There were negative correlation between T2* and AOFAS or ATRS scores (r=-0.92,-0.90,both P＜0.01).Conclusion The T2* value of pathologic AT increases.The quantitative MRI UTE-T2* can evaluate AT from the biochemical structure and correlates with clinical outcomes,which is helpful to diagnose AT in the early stage.

Objective To visualize the pelvic floor structures by translabial three‐dimensional(3D) ultrasonography performed during labor and immediately after delivery, and to observe the morphological changes of levator hiatus in intrapartum women. Methods Totally 62 nulliparous women with singleton pregnancy and cephalic presentation in labor ward underwent intrapartum translabial 3D ultrasound examination before cervical dilatation, at 10 cm dilatation and immediately after delivery. Volume datasets were obtained at rest, biometric measurements and observation of the morphological changes of levator hiatus in different stages were determined in the axial plane. Comparative analyses of parameters in three stages were carried out. Results Translabial 3D ultrasound demonstrated the pelvic floor structures of intrapartum women well. All biometric measurements of the hiatus before cervical dilatation were the smallest and became the largest at 10 cm dilatation, showed statistically significant differences. The measurements after delivery got smaller immediately but still significantly larger than those before cervical dilatation ( P <0 0.01). Conclusions Translabial 3D ultrasound examination of the pelvic floor during labor and within the first 2h after delivery is feasible. It seems to be an effective tool to visualize pelvic floor structures in intrapartum women. Hiatal enlargement may be a common consequence of vaginal childbirth.

Previous studies have demonstrated that the Chinese medicine paeoniflorin, derived from the Ranunculaceae plant peony, peony, purple peony root, was able to have anti-inflammatory, anti-ulcer, anti-hypersusceptibility and anti-oxidation activity. In order to elucidate the pesticide effect and the mechanisms by which paeoniflorin exerts its effect of anti-inflammation and immunoregulation on oxazolone-induced colitic mice, disease activity index (DAI) and histological grading of colitis (HGC) were evaluated in animal model. Moreover, the expressions of HBD-2, IL-6 and IL-10 of mice with experimental colitis were observed with immunohistochemistry and RT-PCR in this study. Results showed that DAI and HGC of oxazolone control group was significantly higher than that of normal control group, and that paeoniflorin groups and 5-ASA group, compared with oxazolone control group, could alleviate the symptoms and histological damages of colitic mice (P < 0.05, P < 0.01). The expression of HBD-2 and IL-6 cytokine on the colon of colitic mice was higher than that of normal control, paeoniflorin and 5-ASA groups (P < 0.05, P < 0.01), but the expression of IL-10 is lower than that of normal control, paeoniflorin and 5-ASA groups (P < 0.05, P < 0.01). The positive correlations were demonstrated between the expression of (HBD-2 and IL-6) and DAI (Pearson r = 0.728, Pearson r = 0.758, P < 0.01, respectively), (HBD-2 and IL-6) and HGC (Pearson r = 0.819, Pearson r = 0.825, P < 0.01, respectively), whereas, the negative correlations were demonstrated between the expression of IL-10 and DAI (Pearson r = -0.789, P < 0.01), IL-10 and HGC (Pearson r = -0.725, P < 0.01). It can be concluded that to some extent paeoniflorin effectively alleviate the symptoms of oxazolone-induced colitis through regulating the expression of HBD-2, IL-6 and IL-10.

OBJECTIVE:To shorten the turnover days of hospital drug inventory,reduce the cost of drug inventory and improve the level of hospital drug inventory management.METHODS:The data of 65 kinds of antitumor drugs and its adjuvant drugs during Jan.1st,2016-Dec.31st,2016 were collected from hospital information system (HIS) of our hospital,such as price,inventory to classify by using ABC classification method.According to demanded quantity of class A drugs in the secondary drug storage,the amount purchased of upper and lower limitation of class A drugs could be calculated.The data of class C drugs were analyzed one by one to determine the "temporary use" drug directory.The turnover days of class A drugs and the inventory cost of class C drugs were counted before and after classification management.RESULTS:There were 10 class A drugs,accounting for 15.38％ of total types and 78.27％ of total consumption sum;the turnover days of pharmacy inventory decreased from (43.96 ± 19.04) d to (13.64 ± 8.02) d by adopting the principle of purchasing in small quantity by several times.There were 10 "temporary use" drugs of class C drugs,accounting for 26.32％ of total types,270 thousand yuan inventory cost saved each year.CONCLUSIONS:Hierarchical management of hospital drug inventory by ABC classification can effectively optimize the inventory types and amount,and provide definite evidence for "temporary use" drugs so as to shorten turnover days of pharmacy inventory and recue the cost of pharmacy inventory.

Objective: To quantitatively assess biochemical alterations in the cartilage of the subtalar and midtarsal joints in chronic lateral ankle instability (CLAI) patients with isolated anterior talofibular ligament (ATFL) injuries and combined calcaneofibular ligament (CFL) injuries using MRI T2 mapping. Materials and Methods: This study was performed according to regulations of the Committee for Human Research at our institution, and written informed consent was obtained from all participants. Forty CLAI patients (26 with isolated ATFL injuries and 14 with combined ATFL and CFL injuries) and 25 healthy subjects were recruited for this study. All participants underwent MRI scans with T2 mapping. Patients were assessed with the American Orthopedic Foot and Ankle Society (AOFAS) rating system. The subtalar and midtarsal joints were segmented into 14 cartilage subregions. The T2 value of each subregion was measured from T2 mapping images. Data were analyzed with ANOVA, the Student’s t test, and Pearson’s correlation coefficient. Results: T2 values of most subregions of the subtalar joint and the calcaneal facet of the calcaneocuboid joint in CLAI patients with combined CFL injuries were higher than those in healthy controls (all p < 0.05). However, there were no significant differences in T2 values in subtalar and midtarsal joints between patients with isolated ATFL injuries and healthy controls (all p > 0.05). Moreover, T2 values of the medial talar subregions of the posterior subtalar joint in patients with combined CFL injuries showed negative correlations with the AOFAS scores (r = -0.687, p = 0.007; r = -0.609, p = 0.021, respectively). Conclusion CLAI with combined CFL injuries can lead to cartilage degeneration in subtalar and calcaneocuboid joints, while an isolated ATFL injury might not have a significant impact on the cartilage in these joints.
