Objective To investigate the changes of serum inflammatory mediators in septic rats. Methods Thirty male SD rats were randomly divided into sham operation group(10 rats)and sepsis group (20 rats). The model of sepsis was made by cecal ligation and puncture. Carotid artery blood samples were taken from the sham operation group,and from sepsis group at 0,24,48,72 h after model establishment. Enzyme linked immunosorbent assay(ELISA)was applied to detect the content of serum tumor necrosis factor alpha(TNF α), interleukin 1(IL-1),interleukin element 6(IL-6). Results Serum TNF-α content in the sham operation group was(9. 27 ± 3. 12)ng/ L,and(9. 26 ± 8. 01),(32. 01 ± 4. 52),(55. 22 ± 7. 61),(83. 31 ± 8. 57)ng/ L respectively at 0,24,48,72 h after model establishment in sepsis group. There were significant difference between sham operation group and sepsis group at different time points(P < 0. 01). Serum IL-1in sham operation group was(8. 93 ± 1. 26)ng/ L,lower than that in sepsis group model at 0,24,48,72 h after model establishment ((20. 01 ± 3. 51),(25. 51 ± 2. 79),(59. 67 ± 3. 26),(87. 86 ± 11. 51)ng/ L respectively),and the differences were significant(P < 0. 01). The serum IL-6 level in sepsis group at 0,24,48,72 h after model establishment were(11. 52 ± 2. 32),(31. 59 ± 12. 12),(57. 27 ± 13. 53),(71. 59 ± 12. 67)ng/ L,respectively,different from that of sham operation group((12. 36 ± 3. 25)ng/ L,(P < 0. 01)). Conclusion The serum transmitter levels in septic rats significantly increase,which suggest that a lot of inflammatory mediators are released,and it may be one of the factors for the occurrence of sepsis.

Objective To find out what kind of disease the uterine mass diagnosed by B-ultrasound is and discuss its outcome treated by hysteroscopy. Methods 78 cases of uterine mass were treated by hysteroscopy in our hospital from Auguest 2000 to July.2001, Masses were detected,cut out and sent for pathologic diagnosis. Results sixty-two cases (79.49%)(62/78)came to see their doctors with the symptoms,including abnormal bleeding (58) and abnormal discharge or abdominal pain(4).The other 16 cases were detected in regular physical examination without any complaint.No complication occurred during the operation.The results of pathology were as follows:endometrial polyp 51.3%(40/78),simplex hyperplasia 20.5%(16/78),complex hyperplasia 1.3%(1/78),atypical hyperplasia 2.6%(2/78),endometrial adenocarcinoma 1 3% (1/78),leiomyoma or adenomyoma 14.1%(11/78),incomplete abortion 1.3%(1/78),and no abnormolily 5 cases(6.4%).Thirty-five cases of mass were discovered in postmenopausal women and 85.7%(30/35)of cases were benign.Sixty-nine patients(88.5%)were followed up for (2～12)months after the operation.Sixty-five of them were satisfied with treatment.The satisfying rate was 94.2%.Especially with the postmenopausal women,all 31 cases were satisfied with the operation though 4 cases no longer contacted us. Conclusions Most of utering masses diagnosed by B ultrasound are benign.Hysteroscopy therapy is an appropriate method for the uterine mass in postmenopausal women.

Objective To investigate the role of phosphatidylinositol 3-kinase (PI3K)/protein-serine-threonine kinases(Akt) signal transduction pathway in EphB receptor-mediated neuropathic pain in rats.Methods Forty-eight pathogen-free male SD rats aged 2-3 months weighing 150-180 g were randomly divided into 6 groups (n =8 each):groups sham operation (groups S1 and S2 ); groups chronic constrictive injury (CCI) (groups C1and C2 ) and groups EphBI-Fc (EphB receptor antagonist) + CCI (groups E1 and E2 ).Neuropathic pain was induced by placing 4 ligatures on left sciatic nerve at 1 mm intervals with 5-0 silk thread in groups C1,C2,E1 and E2.EphBI-Fc 0.5 μg in 5 μl normal saline was injected intrathecally 1 h before operation and at 1 and 2 d after operation (group E1 ) or on 5th day after operation (group E2).Normal saline 5 μl was injected intrathecally instead of EphBI-Fc 1 h before operation and at 1 and 2 days after operation (groups S1 and C1 ) or on 5th day after operation (groups S2 and C2 ).Pain withdrawal latency to noxious thermal stimulation (PWL) and pain withdrawal threshold to noxious mechanical stimulation (PWT) were measured before operation and at 1,3 and 5 d after operation.The animals were sacrificed at 5 d after operation after measurement of pain threshold.The lumbar segment of spinal cord (L4-6) was removed for determination of c-Fos,PI3K and phosphorylated Akt(p-Akt) expression.Results CCI significantly reduced PWL and PWT and up-regulated spinal c-Fos,PI3K and p-Akt expression in groups C1 and C2 as compared with groups S1 and S2.EphB1-Fc significantly decreased hyperalgesia and the upregulated spinal Fos,PI3K and p-Akt protein expression induced by CCI in groups E1 and E2 as compared with groups C1 and C2.Conclusion Spinal EphB receptor is involved in the development and maintenance of neuropathic pain through PI3K/Akt signal transduction pathway.

Objective To investigate the clinicopathologic characteristics of premalignant and malignant endometrial polyps (EP) in premenopausal and postmenopausal women.Methods A retrospective analysis was conducted in 42 cases of premalignant and malignant EP from 1993 to 2012.Polyps were classified into premenopausal (group A,10 cases) and menopausal (group B,32 cases),including 26 cases of endometrioid adenocarcinoma,4 of clear cell carcinoma,9 of serous adenocarcinoma,and 3 of atypical hyperplasia.Results The prevalence rate of premalignant and malignant EP was 1.42％ (42/2 965),the prevalence rate of malignancy in postmenopausal and postmenopausal women was 0.48％ (10/2 064) and 3.55％ (32/901),respectively.The mean size of EP was (1.6 ± 0.8) cm,abnormal uterine bleeding was positive in 90％ (38/42) of cases.The EP pathological diagnosis showed all were endometrioid adenocarcinoma in group A,while there were 4 of clear cell carcinoma,9 of serous adenocarcinoma in group B.The mean size of EP was (1.1 ± 0.6) and (1.7 ± 0.9) cm in group A and B respectively (P ＜0.05).According to immunohistochemistry,all cases of group A were ER positive,but 41％ (11/27) of group B were ER negative (P =0.059).The PR positive rate was 8/9 and 56％ (15/27) in group A and B,respectively (P =0.169).Conclusions The risk of the EP malignancy rate is higher,while ER,PR positive rate are lower in postmenopausal womcn.Postmenopausal EP,especially accompanied by abnormal uterine bleeding and large polyps should be removed as soon as possible.

BACKGROUND: Radix astragali has the effect of protecting cells from damage in ischemic reperfusion, whether pre-treatment with radix astragali can protect myocardial eells from apoptosis in ischemic reperfusion ? OBJECTIVE: To investigate the effect of pre-treatment with radix astragali on apoptosis and its relative genes in rats with ischemic myocardial reperfusion DESIGN: A randomized and controlled trial taking Wistar rats as experimental subjects.SETTING: The Basic Medical Department of Chengde Medical College and the Geriatric Department of the Affiliated Hospital.MATERIALS: The experiment was completed in the Imunnohistochemical Laboratory of Basic Medical Institute in Chengde Medical College from February to December in 2004. A total of 30 healthy male Wistar rats were selected, and at random classified as groups of radix astragali pre-treated (radix astragali), ischemic reperfusion and psuedo-operated (control), 10 rats for each group.METHODS: Radix astragali injection was given peritonealy for rats in radix astragali pre-treated group before operation, and the equivalent normai saline was given for those in ischemic reperfusion and psuedo-operated groups. One week later, the model of ischemic reperfusion was set up. After operation the myocardia in marginal zone of ischemic reperfusion were sampled, and the myocardia of the corresponding zone were taken for control group. The method of terminal (TdT)-mediated dUTP-biotin nick end labeling (TUNEL) was used for assay of myocardial apoptosis rate, and the ABC immunohistochemical method was used for assay of myocardial bcl-2 (inhibiting apoptosis gene) and bax (promoting apoptosis gene).MAIN OUTCOME MEASURES: Apoptosis rates, and expression of bcl2 and bax genes of myocardia RESULTS: ① Apoptosis rate of myocardial cells: The rate in radix astragali group was decreased compared with that in ischemic reperfusion group [ (14.06 ±9.97) ％, (19.34±12.30) ％, t = 1.863, P ＜ 0.05].② Expression of bcl-2: There was no significant difference between radix astragali and ischemic reperfusion groups[(9.14±4.46) ％, (8.99±4.54) ％, P ＜ 0.05].③ Expression of bax: The expression in radix astragali group was decreased compared with that in ischemic reperfusion group [(12.65 ±7.23)％,(18.12±7.92) ％, t = 2.096, P ＜ 0.05]CONCLUSION: Pre-treatment with radix astragali can down-regulate the expression of promoting apoptosis gene so as to reduce the rate of myocardial cell apoptosis, hence it can protect the myocardial cells in ischemic reperfusion.
