Objective To analyze the clinical relationship of progesterone(P) and estradiol(E2) for embryo arrest in early pregnant patients.Methods 118 patients with embryo arrest in early pregnancy were selected and divided into two groups,research group (58 cases,embryo arrest in early pregnancy) and control group (60 cases,threatened abortion but embryo keeping growth by tocolysis).Serum P and E2 were measured and compared between two groups.Receiver operating characteristic curves(ROC) of all indexes were drawn and the areas under the ROC curves were calculated to evaluate diagnostic value.Results Compared to control group,the serum P and E2 were lower in research group(P ＜ 0.05).To diagnosis embryo arrest,the threshold for P was less than 118.4nmol/L,with 93.9％ sensitivity and 87.3％ specificity; while the threshold value for E2 was less than 1110pmol/L,with 95.6％ sensitivity and 90.7％ specificity.Conclusion Detection of serum P and E2 may be helpful for the diagnosis of embryo arrest in early pregnancy,and the serum E2 had the best diagnostic value.

Heme oxygenase(HO) is the rate-limiting enzyme in the degradation of heme.Three HO isoforms have been identified:HO-1,HO-2 and HO-3.The substances of heme degradation,carbon monoxide(CO),biliverdin and free iron(Fe~(2+)),have an important function in anti-oxidant and protecting cells.And the anti-oxidant function of induction HO-1 expression is mediated in the signal transduction of HO-1 gene expression and the promoter of HO-1 gene in the cells.So the new way is provided in the relevent liver-injury which is caused in anti-oxidant stress or non-oxidant stress.

Objective To develop a port expander for simple network cable tester,which can raise the testing efficiency of the computer network twisted-pair.Methods Several RJ-45 sockets were used to connect the eight points separatedly according to the same arrangement order.One socket was connected to testing port by short twisted-pair,while other sockets were used as expander port.Results In practical test,the operation only needs one person,who could test the computer network twisteded-pair conveniently without going back and forth frequently between the two terminals of the tested line.Conclusion It is proved by testing that the port expander for the simple network cable tester can raise the testing efficiency of the computer network twist-pair.

Currently, Lemology in PLA is facing two challenges: i) the threat of emerging infectious diseases (EID), bioterrorism and biological warfare (BW); ii) professional staffs are concerned over their development while the armed forces are undergoing re-organization. Whereas military lemology meets several opportunities such as: Ⅰ) the discipline occupies\ a\ prominent portion in military medicine; Ⅱ) an outbreak of EID and the threat of bioterrorism are closely related to military medicine; Ⅲ) infectious diseases are still common diseases prevalent in both servicemen and civilians; Ⅳ) the present status of lemological study in PLA is in the leading position in the whole nation; Ⅴ) once there should be another outbreak of SARS epidemic such as occurred in 2003 in Beijing, the most expeditions and effective approach is still to deploy the specialists in PLA organizing a medical team to enter the epidemic area. The development strategy of this discipline in PLA is proposed as follows: i) expanding the scope of the discipline; ii) further the construction of the team; ii) perfecting the system for prevention and treatment of EID. Finally, the presumption for the 21st century of the subject is following suggestions are the contemplation for the development of this discipline in the 21st century: i) further emphasize the study of this discipline is beneficial for both military and civilian; ii) to simplify the scope of the discipline is not against its enhancement; iii) the interchanges and collaboration among different disciplines should be encouraged and strengthened.

Objective To analyze the situation of secondary hypertension caused by different etiology and its treatment status so as to improve its treatment. Methods Totally 580 patients with secondary hypertension selected with strict criteria were divided into 4 groups in accordance with the etiology. The data were dealt with SPSS 13.0. We analyzed the sex, age, systolic pressure, diastolic pressure and positive incidence of family history of all the secondary hypertension patients in each group, and compared their usage of every unilateral preparation. Results The average age of renal parenchymal disease was more advanced than that of adrenal disease and other diseases. The administration of diuretics and angiotensin-converting enzyme inhibitor (ACEI) in renal parenchymal disease group, αβ receptor blocking agents and calcium antagonists in kidney-artery disease group, a antagonists in adrenal disease and compound antihyportensive agents in other diseases groups all affected advantage of the ratio. Conclusion Diuretics and ACEI are suitable for hypertension caused by renal parenchymal disease, αβ receptor blocking agents and calcium antagonists are suitable for that caused by kidney artery disease, but a receptor blocking agents are suitable for that caused by adrenal disease.

Objective To investigate the changes and clinical significance of cerebrospinal fluid (CSF) non-protein-bound iron and malondialdehyde(MDA) in preterm infants with severe intraventricular hemorrhage (IVH) after serial lumbar punctures.Methods Non-protein-bound iron and MDA of CSF in twenty severe IVH preterm infants with first and end lumbar puncture were examined respectively.The control samples were determined for once from first to second week after birth.Results Both Non-protein-bound iron and MDA levels of the first CSF sample in twenty severe IVH preterm infants were higher than that in control[(0.66±0.38)μmol/L vs (0.24±0.12)μmol/L(P<0.01);(1.21±0.41)μmol/L vs (0.89±0.35)μmol/L(P<0.05)].Non-protein-bound iron levels of first and end CSF sample in severe IVH with posthemorrhagic ventricular dilatation (PHVD) were both higher than those without PHVD [(0.75±0.34)μmol/L vs (0.54±0.31)μmol/L;(0.57±0.21)μmol/L vs (0.35±0.18)μmol/L](P<0.05).However,there was no significant difference in MDA levels between both groups.The levels of non-protein-bound iron of end CSF in severe IVH with and without PHVD were significantly lower than those of the first CSF samples (P<0.05),while,there was no significant difference in MDA levels between the end and first CSF samples.Conclusion The non-protein-bound iron and MDA of CSF in severe IVH preterm infants were both significantly increased,non-protein-bound iron and oxygen free radicals may be involved in the preterm brain injury.Serial lumbar punctures can lower the levels of non-protein-bound iron in CSF.

This study investigated the reversal effect of isotetrandrine, an isoquinoline alkaloid extracted from Caulis mahoniae, on P-glyeoprotein-mediated multidrug resistance in human breast cancer doxorubicin-resistant (MCF-7/DOX) cells. RT-PCR assay and immunity histochemistry assay were used to determine the expression level of mdrl gene and P-gp in MCF-7/DOX cells to elucidate resistant character of MCF-7/DOX cells. The activity of isotetrandine to enhance doxorubicin cytotoxicity was tested using MTT (3-(4,5-dimethyhhiazol)-2,5-diphenyltetrazolium bromide) assay and was evaluated by the reversal fold (RF) values. Intracellular accumulation of doxorubicin was assessed by the determination of doxorubicin-assoeiated fluorescence intensity. Effect of isotetrandrine on the expression level of P-gp in MCF-7/DOX cells was then determined by immunity histochemistry assay. The ability of isotetrandrine to inhibit P-gp function was evaluated by detecting the accumulation and efflux of rhodamine123 ( Rh123 )with flow cytometry (FCM). Verapamil was employed as a comparative agent in whole experiment. The results indicated that MCF-7/DOX cells had phenotype of MDR and that the positive expression of P-gp MCF-7/DOX cells and reversal fold (RF) was significantly higher than that of verapamil (P < 0.05 ), butit hardly affected cytotoxicity of DOX in MCF-7 cells and the expression level of P-gp in MCF-7/DOXcells. The ability of isotetrandrine to inhibit P-gp function was reversible, because incubation of MCF-7/DOX cells with isotetrandrine caused a marked increase in uptake and a notable decrease in efflux of Rh123 and a marked increase of intracellular DOX concentrations. In conclusion, isotetrandrine exhibited potent effect on the reversal of P-gp-mediated MDR in vitro, suggesting that it might become a candidate of effective MDR reversing agent in cancer chemotherapy.
