Objective: To develop the continuous adding test for Nationwide Conscription.Method: The computer-based continuous adding test was developed and was administered to 24019 recruited young people among China and 1900 new recruits. When the 3-month-depot training finished, the 228 supervisors of the soldiers were investigated on the soldiers' working performance based on intelligence. Through the data, the test mode and cut-off scores were developed, and the reliability and validity was analyzed. Results: the cut-off scores were that finishing 26 items successfully in 120 seconds and the correct rate was higher than 30%. The retest reliability was 0.78 and the academic statues and the predicting congruence rate of the test was 94.7%.Conclusion:The continuous adding test was applicable as one of enlistee's primary qualification test.

Wogonin is a kind of natural flavonoid compound. According to findings in the latest studies, wogonin shows a wide range of antitumor effects, with the characteristics of multi-pathway, multi-link and multi-target, such as promoting tumor cell apoptosis through ROS or Ca(2+)-mediated signal paths, enhancing tumor cytotoxicity by TNF-α and TRAIL, blocking tumor cell cycle, inhibiting tumor angiogenesis and resisting cancer synergistically with chemotherapeutic drugs. Moreover, Wogonin could enhance body immune function by enhancing immune cell infiltration, regulating the immune cell phenotype and promoting relevant cytokine secretion. In this paper, the authors summarized the advance in studies on wogonin's antitumor and immunomodulatory effects.

In order to solve the problems of erratic drug absorption and low bioavailability after oral administration for poorly-water soluble drugs due to low solubility, a series of novel pharmaceutical dosage forms as solid dispersion, liposome, microemulsion, vesicle, cyclodextrin inclusion complexes and drug nanocrystal have been developed in recent years. Among which drug nanocrystal attracts more attentions for its simpler preparation method, higher drug loading and easier manufacturing technology in the design of dosage forms suitable for different administration routes. In this paper, the nanocrystals of the poorly-water soluble drugs prepared based on bottom-up and top-down technologies were introduced. The characteristics and applications of the nanocrystal-based dosage forms as suspension, tablet and capsule were also introduced and carefully evaluated with the focus on their pharmacokinetics, pharmacodynamics and tissue targeted drug distribution after delivery by oral administration, intravenous injection and pulmonary inhalation. The advantages of drug nanocrystals in their therapeutics effects over the bulk drugs were discussed together with the inherent mechanism. Finally, the problems existing in basic research and scaled-up manufacture of drug nanocrystal as well as the possible ways of solution were listed out so as to make the nanocrystal-based preparations exert their maximum therapeutic effect after clinical application.

DNA damage response (DDR) in different cell cycle status of human peripheral blood lymphocytes (PBLs) and the role of H2AX in DDR were investigated. The PBLs were stimulated into cell cycle with phytohemagglutinin (PHA). The apoptotic ratio and the phosphorylation H2AX (S139) were flow cytometrically measured in resting and proliferating PBLs after treatment with camptothecin (CPT) or X-ray. The expressions of γH2AX, Bcl-2, caspase-3 and caspase-9 were detected by Western blotting. DDR in 293T cells was detected after H2AX was silenced by RNAi method. Our results showed that DNA double strand breaks (DSBs) were both induced in quiescent and proliferating PBLs after CPT or X-ray treatment. The phosphorylation of H2AX and apoptosis were more sensitive in proliferating PBLs compared with quiescent lymphocytes (P<0.05). The expression levels of anti-apoptotic proteins Bcl-2 were reduced and cleaved caspase-3 and caspase-9 were increased. No significant changes were observed in CPT-induced apoptosis in 293T cells between H2AX knocking down group and controls. It was concluded that proliferating PBLs were more vulnerable to DNA damage compared to non-stimulated lymphocytes and had higher apoptosis rates. γH2AX may only serve as a marker of DNA damage but exert no effect on apoptosis regulation.

Twelve flavonoids were isolated from an ethanol extract of Machilus wangchiana by a combination of various chromatographic techniques including column chromatography over silica gel and Sephadex LH-20 and reversed-phase flash chromatography and HPLC. Their structures were identified by spectroscopic data analysis (IR, MS, and NMR) as (+)-catechin (1), (-)-epicatechin (2), 3'-O-methyl-(+)-catechin (3), 3'-O-methyl-(-)-epicatechin (4), 3, 5, 7, 2', 5'-pentahydroxy flavan (5), (-)-naringenin (6), (-)-eriodictyol (7), (-)-liquiritigenin (8), (2R,3R)-(+)-dihydrokaempferol (9), (2R,3S)-(-)-dihydro- kaempferol (10), (2R, 3R)-(+)-taxifolin (11), and quercetin (12). Compounds 1-10 are isolated from the genus Machilus for the first time.

In order to study the stability of akebia saponin D (ASD) in biological fluids in vitro, the determination methods of ASD were established in this study. Akebia saponin D was dissolved in artificial gastric juice, intestinal juice and gastrointestinal contents of rats, respectively, then thermostatically maintained at 37 degrees C. At time intervals after degradation, samples were withdrawn and the concentrations of ASD were determined by HPLC, from which stability of it at different biological specimen was evaluated. As a result, ASD was totally degraded in large intestinal contents of rats in 8 hours. ASD was very stable in artificial gastric juice, intestinal juice and gastric contents of rats. All of the above data proved that ASD was easily degraded by coliform bacteria but stable in acid environment and with the presence of digestive enzyme.
