Objective To explore the clinical characteristics and the influence factors of prognosis of ad -vanced ovarian cancer patients after abdominal metastases .Methods We retrospectively analyzed 65 cases dur-ing January 2013 to January 2016 in the First People′s Hospital of Tianmen .The patients were diagnosed clearly with pathological ,diagnosed for the first time and has the complete clinical data including peritoneal metastases in 58 cases,which were analyzed for single factor and multiple factors of influencing factors survival analysis .Results 58 cases of patients with diagnosis of peritoneal metastasis in ovarian cancer that the average is (49.2 ±6.5), from ovarian cancer diagnosis to abdominal metastases for an average time of 11 months,ovarian cancer patients with peritoneal metastasis of the median survival time was 8 weeks,but 7 cases without abdominal metastases that the median survival time was 15 weeks.The single factor survival curves(Kaplan-meier)showed that marital sta-tus,reproductive history,history of breastfeeding,malignant ascites,neoadjuvant chemotherapy,comprehensive treatment(chemotherapy and tumor cells to destroy the loss and laparotomy abdominal hot perfusion chemothera -py) ,peritoneal metastasis tumor number ,residual lesion size ,quality of life in patients with residual lesions ( KPS scores),D-dimer level in plasma and urine trace albumin levels related to the prognosis of patients (P<0.05). Conclusion Patients with advanced ovarian cancer patients with peritoneal metastasis survival time is shorter , and also company with poor prognosis;Neoadjuvant chemotherapy combined tumor cells to destroy the loss and postoperative intraperitoneal hot perfusion chemotherapy ,short-term curative effect is good ,it can not only im-prove the advanced ovarian cancer treatment effectiveness ,but also improve the quality of life in patients of late phase.The D -dimer level in plasma and urine trace albumin levels before treatment have remained in the pa-tients with high level or not reduce ,treatment effect and prognosis was poor .These can be used as a new index of judging prognosis .

Objective To explore the relationship among emotional resilience,stress and school adjustment.Methods Adolescent life events check-list,adolescent emotional resilience scale and school adjustment scale of middle school students were conducted among 394 junior high school students.Results (1)The emotional resilience score and emotion recovery score of male junior high school students(46.07±8.56,24.43±5.80) were higher than that of female ones(44.39±8.39,23.27±5.37),and the differences were statistically significant(t=1.97,2.05,P＜0.05).The total score of emotional resilience(45.46±8.50,44.83±8.56) was not statistically related with whether they were the only children(t=0.68,P=0.50).The emotional resilience score and positive emotion score of rural junior high school students(44.04±8.53,20.63±5.35)were lower than that of urban ones (46.46± 8.34,22.15 ±4.72),and the differences were statistically significant(t=-2.86,-2.99,P＜0.01).The total score of emotional resilience (47.23±7.82,44.63±8.45,43.00±8.97) in different grades was statistically significant (F=8.86,P=0.00),and the first grade students were higher than the second and third year students.(2)Psychological stress was negatively related with emotional resilience and school adjustment(r=-0.23～-0.35,P＜0.01),and emotional resilience was positively correlated with school adjustment(r=0.12 ～ 0.29,P＜0.01).The relationship between stress and school adjustment were mediated by positive emotion and emotional recovery (the mediating effect were 11.11％,21.15％).Conclusion Frotional resilience plays a mediating role between psychological stress and school adjustment.

Objective To evaluate the role of protein kinase Cα( PKCα)?nuclear factor E2?related factor 2 ( Nrf2)?heme oxygenase?1 ( HO?1) signaling pathway on endotoxic shock?induced acute lung injury ( ALI) in rabbits. Methods Thirty healthy male New Zealand white rabbits, aged 2 months, weighing 2?0-2?5 kg, were randomly divided into 3 groups ( n=10 each) using a random number table: normal control group ( group C);ALI group ( group ALI);PKCα inhibitor chelerythrine group ( group CHE) . In group CHE, chelerythrine 8 mg∕kg ( in 0?5 ml of DMSO) was injected intraperitoneally, and 30 min later, LPS 5 mg∕kg ( in 2 ml of normal saline) was injected via the auricular vein to induce ALI in ALI and CHE groups. The rabbits were then sacrificed at 6 h after injection of LPS or normal saline, and the lungs were removed for examination of the pathological changes which were scored and for determination of wet∕dry lung weight ratio ( W∕D ratio) , and the expression of Nrf2 and HO?1 protein and mRNA. Results Compared with group C, the pathological score and W∕D ratio were significantly increased, and the expression of Nrf2 and HO?1 protein and mRNA was up?regulated in ALI and CHE groups. The pathological score and W∕D ratio were significantly higher, and the expression of Nrf2 and HO?1 protein and mRNA was lower in group CHE than in group ALI. Conclusion The PKCα?Nrf2?HO?1 signaling pathway is one of the endogenous protective mechanisms underlying endotoxic shock?induced ALI in rabbits.

Objective To explore the effect of chronic intermittent hypoxia (CIH) on hippocampus neuron and growth associated protein-43 (GAP-43) in rats. Methods 40 adult male Sprague-Dawley rats were randomly divided into control group, CIH 1 week group, CIH 3 weeks group and CIH 5 weeks group with 10 rats in each group. The CIH groups were exposed to intermittent hypoxia in designed cabin 8 hevery day for 1 week, 3 weeks and 5 weeks. The pathological changes of hippocampal neurons were observed by HE staining. The GAP-43 expression of hippocampus was detected by immunohistochemical staining. Results There was degeneration and necrosis of hippocampal neurons in the CIH rats, and it became worse gradually along with the hypoxia. Compared with the control group, the GAP-43 expression in hippocampus increased in CIH rats. The peak of GAP-43 expression appeared in the 1st week (P=0.038) and then it decreased in the 3rd week (P=0.382) and it was closed to the normal level in the 5th week (P=0.860). Conclusion Degeneration and necrosis of hippocampal neurons exacerbated gradually along with the hypoxia, while GAP-43 expression changed inconsistently.

Objective To study the effect of low frequency electrical stimulation on hormone levels in organs of Chinese tree shrews after death.Methods Giving Chinese tree shrews low frequency electrical stimulation.At 0 h, 3 h, 6 h, 12 h, 18 h, 24 h, 36 h and 72 h after death, the thyroid, liver, spleen were taken,and the levels of endothelin (ET), atrial natriuretic factor( ANF) , thromboxane ( TX) were determined by RIA method.At 0 h after death, midbrain ventral tegmental area ( VTA) of Chinese tree shrews was taken to detect the c-fos expression.Results After electrical stimula-tion, ET, ANF, TX levels in the cadaver organs and VTA c-fos expression of Chinese tree shrews were significantly in-creased than in the control group.The contents were decreasing with the time after death.Conclusions Low frequency e-lectrical stimulation can induce the synthesis and release of hormones in organs and c-fos expression in brain tissue of Chi-nese tree shrews.

This study aimed at investigating the utilization of TCM services and exploring the influencing factors,such as education,economic condition,health condition,attitude to TCM treatment and TCM health literacy,of TCM treatment-seeking behavior in the elders in Zhejiang Province.In this study,a cross-sectional study with stratified sampling was adopted for the further investigation of the elders over 55 years by questionnaire.The questionnaire contained four aspects:1.demographic information:gender,age,education,pension mode,medicare and self-evaluation of economic level;2.health status:self-evaluation of health and current diseases;3.attitude to TCM treatment:Would you accept the TCM health services? 4.health literacy:self-made KAB questionnaire including health knowledge,attitude and behavior.Nine hundred and fifty questionnaires were issued and 945 valid questionnaires were returned.Among them,four hundred and eighty-four cases were male and 461 were female.The average age was 72.0 ± 8.9 years with a low level of education,mainly junior high school or lower (88.3％).Over the past year,only 50.11％ elders sought for TCM treatment.Generally speaking,age,gender,education,pension mode and health behavior showed no significant association with TCM treatment.The elders seeking for TCM treatment over the past year held favorable attitude to TCM treatment and high economic status,yet,with poor health status,high prevalence and health literacy (or health attitudes).It was concluded that the utilization rate of TCM services in the elders in Zhejiang Province was not optimist,probably resulting from the lack of publicity and market competitiveness of TCM.Therefore,TCM services should be promoted to meet the health needs of the elders and enhance the utilization rate of TCM services for the achievement of a significant role in the aging society in China.

Objective To evaluate the effect of sevoflurane pretreatment on the inflammatory response during renal ischemia-reperfusion (I/R) in rats.Methods Thirty pathogen-free male Sprague-Dawley rats,aged 12-14 weeks,weighing 220-260 g,were randomized into 3 groups (n =10 each) using a random number table:sham operation group (group S),I/R group and sevoflurane pretreatment group (group SP).Renal I/R was induced by clamping the left renal pedicle for 45 min followed by reperfusion in I/R and SP groups.In group S inhalation of 3％ sevoflurane in O2 was started at 30 min before I/R and maintained throughout the experiment.Venous blood samples were taken at 3 h of reperfusion for determination of serum blood urea nitrogen (BUN) and creatinine (Cr) concentrations.The animals were then sacrificed and the left kidneys were removed for microscopic examination and for measurement of the content of tumor necrosis factor-apha (TNF-α),interleukin-6 (IL-6) and intercellular cell adhesion molecule-1 (ICAM-1) in renal tissues (by ELISA).Results Compared with group S,the serum BUN and Cr concentrations,severity of necrosis of renal proximal convoluted tubules (0 =normal,4 =necrosis of whole segment of proximal convoluted tubules),and contents of TNF-α,IL-6 and ICAM-1 were significantly increased in I/R and SP groups (P ＜ 0.05).Compared with group I/R,the serum BUN and Cr concentrations,severity of necrosis of renal proximal convoluted tubules,and contents of TNF-α,IL-6 and ICAM-1 were significantly decreased in SP group (P ＜ 0.05).Conclusion Sevoflurane pretreatment can protect kidney against I/R injury by inhibiting the inflammatory responses in the renal tissues of rats.

BACKGROUND: The existence of minimal residual leukemia cells is the main cause for the recurrence of acute leukemia in children, and immunological biological therapy has attracted more and more attentions in the various methods from eliminating minimal residual disease. Previous studies have found that interferon α-2b can effectively inhibit the increase of tumor cells in vivo in children with neuroblastoma and malignant lymphoma, whether it can inhibit the increase of leukemia cells?OBJECTIVE: To investigate the effects of interferon α-2b in vitro on leukemia cells.DESIGN: A comparative observation taking human promyelocytic leukemia HL-60 cell line as the material.SETTING: Cell Culture Room; Immunological Laboratory; Cell Room, Institute of Pediatrics, Affiliated Hospital,Medical College of Qingdao University.MATERIALS: HL-60 cell line was provided by Shandong Institute of Basic Medical Sciences. Interferon α-2b was purchased from Megagene Company Fluorescein isothiocyanate (FTTC) rabbit-anti-rat Ig solution (CatEK001) and CD13 anti-human monoclonal antibody solution (Cat. DK013Y) were purchased from Union Stem Cell & Gene Engineering Co.,Ltd.METHODS: The experiments were carried out in the Institute of Pediatrics, Affiliated Hospital, Medical College of Qingdao University from March to September 2005. HL-60 cells culture system was established in vitro, and the oncentration was adjusted to 1×109 L-1. The cells were divided into control group and experimental group. In the experimental group, each well was added by interferon-α-2b with the terminal concentration of 5×105, 1×106, 2×106,5×106 and 1×107 U/L, respectively. In the control group, each well was added by saline of the same volume. The cells were cultured continuously for 48 hours. The morphological changes of HL-60 cells were observed using Wright's staining under light microscope; Cell apoptosis was observed using acridine orange/ethidium bromide double staining; Antigen expression and maturation and differentiation on cell membrane were observed by determining CD13 protein expression; Proliferation and activity of HL-60 were detected with methyl-thiazol-tetrazolium (MTT) assay.MAIN OUTCOME MEASURES: The occurrence of apoptosis was judged according to the uniformity and staining of HL-60 nuclear chromatin; HL-60 cell proliferation was judged according to the absorbance (A) value; The maturation of HL-60 cells was judged according to the number of positive CD13 cells.RESULTS: ① HL-60 cell apoptosis: The cells were cultured for 48 hours. When the concentration of interferon α-2b was 5×105 U/L, there were mainly early apoptotic HL-60 cells; When the concentration was 1×107 U/L, there were mainly late apoptotic cells, and the apoptotic rate was significantly higher than those in the control group (P ＜ 0.01 ).② HL-60 cell proliferation: The A values in the experimental groups treated with interferon α-2b of 2×106 U/L and 1 ×107 U/L were significantly lower than that in the control group (P ＜ 0.01). ③ Maturation of HL-60 cells: The percentages of positive CD13 cells in the experimental groups treated with interferon α-2b of 1 ×106 and 1 ×107 U/L were significantly lower than that in the control group (P ＜ 0.01).CONCLUSION: It is concluded that interferon α-2b can enhance the apoptosis, inhibit the proliferation and promote maturation and differentiation of HL-60 cells.
