Objective To evaluate cortisol level in experimental frequent febrile seizures model rats.Methods Rats were divided into 3 groups: normal control group(n=10,NC group),hyperthermic control group(n=12,HC group) and febrile seizures group(n=21,FS group).Cortisol level in serum and hippocampus of rats were determined by ELISA.Ultrastructural changes of neurons in hippocampal region CA1 was observed by electron microscop.Results 1.No special ultrastructual findings were observed from neurons in hippocampal CA1 in NC and HC group.In FS group,the neuronal degeneration and edema,the mitochondrial degeneration and edema,the mitochondrion ridge obscured or disappeared.2.Cortisol levels in serum and hippocampus in FS group [(26.57 ? 15.94)?g/L and((4.11)?1.74)?g/L,respectively] were significantly lower than those in HC group [(40.04 ? 15.72)?g/L and(6.70?3.45)?g/L,respectively](P0.05).Positive correlations were demonstrated between serum cortisol level and hippocampus cortisol level(r=0.40 P

0.05).Conclusions Frequent FS might not change the expression levels of IL-6 and TNF-? in hippocampus.IL-6 and TNF-? might not play a role in development of FS induced brain damage.

Objective To study the expression of urokinase-type plasminogen activator (uPA) and its relation with expression of receptor (urokinase-type plasminogen activator receptor uPAR) in epithelial ovari- an cancer (OEC) and with the clinic prognosis.Methods Expression of uPA and uPAR protein was detected by Streptavidin-biotin-HRP in 68 cases of epithelial ovarian cancer and compared with that in 10 cases of borderline tumor,10 cases of benign tumor and 10 cases of normal tissue,and correlation between them was analyzed.The different expression groups of uPA was correlated with the prognosis of ovarian epithelial can- cer.The expression of uPA showed a correlation with short survival time (P

This study examined the role of PI3K/Akt pathway in radiosensitization of DNA damage of cervical carcinoma cells. The 50% inhibition concentration (IC(50)) of cisplatin and docetaxel in HeLa cells was detected by Mono-nuclear cell direct cytotoxicity assay (MTT) in vitro. HeLa cells were treated by cisplatin/docetaxel of 10 percent of IC(20) alone or combined with LY294002 for 24 h, and then radiated by different doses of X-ray. The cell survival ratio was obtained by means of clone formation. One-hit multi-target model was fitted to the cell survival curve to calculate dose quasithreshold (Dq), mean lethal dose (D(0)), 2Gy survival fraction (SF(2)) and sensitization enhancement ratio (SER). The pAkt and total Akt expression was detected by Western blotting and DNA damage by neutro-comet electrophoresis. The HeLa cells were randomly divided into 7 groups in terms of different treatments: Control; radiation treatment (RT) group; LY294002+RT group; cisplatin+RT group; docetaxel+RT group; LY294002+cisplatin+RT group; LY294002+docetaxel+RT group. The apoptosis ratio of each group was measured by flow cytometry. The results showed that docetaxel and cisplatin significantly enhanced the phosphorylation of Akt in radiation-treated HeLa cells. The Dq, D(0) and SF2 in LY294002-contained groups were lower than those in docetaxel or cisplatin+RT group. The SER in the LY294002+docetaxel+RT group was 1.35 times that of the docetaxel+RT group, and that in the LY294002+cisplatin+RT group 1.26 times that of the cisplatin+RT group. The Comet electrophoresis showed that tail distance in the LY294002+cisplatin+RT group or LY294002+docetaxel+ RT group was longer than in the cisplatin+RT group or docetaxel+RT group. The apoptosis ratio in the LY294002+cisplatin+RT group or LY294002+docetaxel +RT group was higher than in the cisplatin+RT group or docetaxel+RT group. It was concluded that inhibiting PI3K/Akt pathway can increase the effect of docetaxel and cisplatin on the radiosensitivity of HeLa cells and DNA damage resulted from radiation.

Objective:To explore the clinical value of remote ECG consultation for primary medical institutions. Methods:Remote ECG consultation data for medical institutions of different levels in Hubei Jianli county were sta-tistically analyzed.Results:In county hospitals of this area,there were 1334 cases of ECG consultation,the positive rate was 41.00% (547/1334),and the three abnormal ECG types with highest incidence rate were arrhythmia (27.29%),left ventricular hypertrophy (LVH,9.15%)and ST-T change (2.62%)in order;in rural health rooms of this area,there were 723 cases of ECG consultation,the positive rate was 55.19%(399/723),and the three ab-normal ECG types with highest incidence rate were arrhythmia (34.02%),ST-T change (11.07%)and LVH (5.39%)in order.Conclusion:The remote ECG consultation is easy to perform.It can rise the detection rate of transient abnormal ECG events in rural area,where is lack of ECG equipment and personnel,so it is worthy of ex-tending.

Objective To analyze current situation and problems of health manager training in the pilot training areas. Method With the recommendations of health administration deputies in the plot areas of Shanghai, Chongqing and Urumqi, 2 centers for community health services (CHSs) were selected in each area, 9 relative persons were interviewed, 3 focus group discussions (FGDs) involved 18 persons were held totally. The FGDs focused on such questions as“the general information of the training students”“the objectives and purposes of the training in each area”, and so on. Field investigation and qualitative analysis were used to investigate the status quo and main problems of the training of health manager in the pilot areas. Result The problems of the training of health manager existing in the pilot areas mainly are:part of teachers were not fully competent to the training of health manager, training of operant skill was insufficient, training course was not unified, the assessment mechanism was not perfect. Conclusion Optimizing the construction of teachers team, standardizing the training content, increasing the time of operating skills training, establishing a unified and standardized assessment mechanism are essential.

Objective To exlore clinical characteristics and changes of electroencephalography(EEG) in children with migraine.Methods Clinical data of 98 children with migraine provided by our hospitals clinic service were analysed.The cases′ history were inquired,physical examination made(EEG),Video-EEG(V-EEG) and transcranial doppler sonography(TCD) were examined.After(diagnosis) was made,the patients were treated and followed up.Results In 98 cases of migraine,27 cases were classical migraine and 71(cases) were ordinary migraine.EEG and V-EEG indicated most of them were in normal range and increase in diffused inactive echoes,and only 1 case of 98 EEG showed scattered epileptic waves;TCD indicated that the velocities of blood flow of intracranial arteries of 87 children with migraine were faster.Conclusions Clinical characteristics of children with migraine is similar with adault.Diagnosis of children with migraine and epilepsy,apply both EEG and TCD have great value in diagnosis of children with migraine.

OBJECTIVETo observe the effect of Qingfei Peiyuan Micro-pill (QPM) on HIV/AIDS patients with pulmonary infection of phlegm heat obstructing lung syndrome (PHOLS).

METHODSTotally 141 HIV/AIDS patients with pulmonary infection of PHOLS were randomly assigned to the treatment group (94 cases) and the control group (47cases). On the basis of Western medicine, patients in the treatment group took QPM. The therapeutic course for all was 28 days. The improvement of symptoms and signs was observed. The body temperature (BT), chest X ray, and white blood cells (WBCs) were detected.

RESULTSThe Chinese medical syndrome score was lower in the treatment group than in the control group at the 7th, 21st, and 28th day of treatment, showing statistical difference (P < 0.05). The efficacy was better in the treatment group than in the control group at the 7th, 21st, and 28th day of treatment, showing statistical difference (P < 0.05). The BT was lower in the treatment group than in the control group on the 7th day. There was no statistical difference in the patient number with normal WBCs on the 7th day (P > 0.05). But there was statistical difference in the patient number with normal WBCs on the 14th, 21st, and 28th day of treatment (P < 0.05). There was no statistical difference in the patient number with normal chest X ray on the 7th and 28th day of treatment (P > 0.05). But there was statistical difference in the patient number with normal chest X ray on the 14th and 21 st day of treatment (P < 0.05).

CONCLUSIONQPM had certain complementary effect on HIV/AIDS patients with pulmonary infection of PHOLS.
