【Objective】To observe the effect of plasma ?-endogenous peptides (?-EP) on gestational function in endometriosis(EMT) rats.【Methods】 Female SD rats at the third estrous cycle were used to establish EMT model.Then 20 EMT rats were equally randomized into the model group and naltrexone(an opioid receptor antagonist) group,and other 10 rats were in the pseudo-operation group.Naltrexone group was given naltrexone 2?mg?kg~-1?d~-1 by gastric gavage during proestrus and normal saline at other time,and the model group and pseudo-operation group were given normal saline for one month.Serum levels of ?-EP,luteinizing hormone(LH) and prolactin(PRL) were examined during proestrus,and serum progesterone(P) level and gestational function were observed after estrus.【Results】Serum levels of ?-EP and PRL increased and LH decreased during proestrus,and serum P level also decreased after estrus in the model group(P

Objective To test the reliability and validity of CRIES-13(Chinese edition). The Children Revised Impact of Event Scale (CRIES-13) was recommened for diagnosing PTSD of children. Methods In the last third of the September 2008,according to the suffering condition,600 students were choosed who were fit for the research standard as subjects in two middle schools randomly. The viability of CRIES-13 was weighted by testretest reliability,Cronbach' s alpha,Split half reliability. The validity of CRIES-13 was analysed by content validity ,criterion validity,construction validity. Results In the test-retest reliability of CRIES-13, the Spearman correlation coefficient of total,intrusion factor,avoid factor,high warkening factor were 0.79, 0.75, 0.71, 0.75. Significant correlation were found among these scores. The Cronbach' s alpha of population was 0. 81. The Cronbach' s alpha of three factors was 0. 79 ( intrusion factor) , 0. 71 ( avoid factor), 0. 65 ( high awarkening factor). CRIES-13's split-half reliability was 0. 85. In the content validity test,the Spearman rank correlation coefficient between total score and each item was 0. 83 (intrusion factor), 0. 75 (avoid factor), 0. 85 (high awarkening factor). The correlation between intrusion factor and avoid factor was 0.63. The correlation between avoid factor and high awarkening factor was 0.41. The correlation between intrusion factor and high awarkening factor was 0.41. In struction validity, variance orthogonal rotation factor analysis was adopted and got three general factors. Their cumulative contribution to total variance was 55.52%. In the criterion validity test,significant correlation was found between intrusion factor and SDQ emotional factor and depression scale total score. Significant correlation was found between high awakening factor and SDQ emotional factor and depression scale total score. Conclusion The reliability and validity of CRIES-13 was good. It could be used extensively.

Objective The Children's Revised Impact of Event Scale (CRIES-13) is used for Screening PTSD of children. The reliability and validity of CRIES-13 is good. To research the demarcation points of CRIES-13 (Chinese version) based on the reliability and validity analysis,and to improve the useful value of the scale.Methods In late September 2008, according affected condition, students were choosed who were fit for the research standard as subjects in two middle schools. First,general questionnaire (self-writing) and CRIES-13 were applied to the subjects. Second, according to K-SADS-PL, physician carried out diagnosis meeting and evaluation to 310 students who were classified by stratified rand sampling. Critical point of CRIES-13 was divided by K-SADSPL. The assessment value of it were sensitivity, specificity, veracity, PPV, NPV. The right choice of division was measured by ROC curve. Results When the critical score was higher than 30, the score of Se ( 0. 833 ), Sp(0. 836) and NPV (0.97) was in the high level. Conclusion When the critical score is higher than 30, the scale have a good discrimination for PTSD, non-PTSD and it can be used extensively.

OBJECTIVE: To explore the mechanisms of Runing Recipe II (a recipe composed of traditional Chinese herbs) in inhibiting the growth of breast cancer by observing its effects on the expressions of p53 and ras oncogene proteins and cell cycle of the transplanted Ca761 breast cancer in mice. METHODS: We established the breast cancer model by transplanting Ca761 cells in mice. The mice were randomly divided into 4 groups: normal saline control group, CTX-treated group, Runing Recipe II-treated group, and Runing Recipe II and CTX-treated group, with 12 mice in each group. We detected the cell cycle of the cancer cells in the mice's transplanted tumor with flow cytometry and measured the expressions of p53 and ras oncogene proteins in the transplanted tumor with immunohistochemical methods. RESULTS: The percentages of tumor cells in S-phase of the Runing Recipe II treated group, CTX-treated group and Runing Recipe II and CTX-treated group were significantly lower than that of the normal saline control group respectively (P<0.05). The percentage of tumor cells in G(0)-G(1) phase of the Runing Recipe II treated group was lower than that of the CTX-treated group (P<0.05), while the percentage of tumor cells in G(2)-M phase was higher than that of the CTX-treated group. The immunoreactive scores (IRSs) of p53 in the Runing Recipe II treated group and Runing Recipe II and CTX-treated group were significantly lower than that in the normal saline control group respectively (P<0.05). The effect of CTX on the expression of p53 was not significant. The IRSs of ras oncogene protein in the Recipe II-treated group, CTX-treated group and Runing Recipe II and CTX-treated group were lower than that in the normal saline control group respectively (P<0.05). CONCLUSION: Runing Recipe II can inhibit the growth of Ca761 breast cancer in mice by controlling the cell cycle of the transplanted tumor. This may be related to its effect on the gene expressions of p53 and ras in the tumor tissue.

Background Blepharitis caused by Demodex infestation is very common in clinical practice.There are various methods mentioned in the study of Demodex infestation in China,but a unified introduction and evaluation of the operating procedures is lacked.A quick and accurate clinical diagnostic method for Demodex infestation needs to be further studied.Objective This study aimed to establish operation procedures for the clinical examination of eyelid Demodex infestation,which were applied to evaluate the conditions of eyelid Demodex infestation in ocular patients with discomfort.Methods One thousand and fifty-two patients with eye dryness,eye itchiness or other symptoms were selected for slit lamp examination and photographing of the eyelid margin area.Three eyelashes with associated scurf from each superior eyelid were plucked out for examination of Demodex under the microscope.Positive findings included observation of Demodex mites or eggs.Their amounts were recorded individually for all eyelash samples.Results A procedure for observing,recording and reporting eyelid Demodex infestations in patients was successfully established.By using this procedure,1 052 patients were investigated for the examination of Demodex infestations.Demodex mites or eggs were found in 582 cases (55.3％).The positive rate of Demodex infestation increased with age,and the population over 60 years group had the highest positive rate,showing a significant difference among the different age groups (x2=10.547,P=0.001).There was no significant difference in positive rate between male patients and female patients (P =0.352).The test turnaround time (TAT) for one examination was (11.4±5.2) seconds.Conclusions The operational procedure for examining the palpebral margin Demodex infestation by the slit-lamp,optical microscope,photographing and laboratory reports is established.It is simple and quick in the appliation for the clinical diagnosis of eyelid Demodex infestation.
