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.

Objective To explore the influence of MYC expression level on ovarian cancer cells adhesion and invasion ability,and the involvement of the integrinβ1 in the adhesion and invasion control. Methods Comparative study was done to analyze the relationship between the mRNA level of MYC and ITGB1 among sixty cell lines from the NCI-60 cells bank; Western blot was performed to demonstrate the correlation of MYC and ITGB1 protein level in ovarian cancer cell lines;Immunohistochemistry was adopted to compare the expression level of MYC and ITGB1 in paired primary and metastatic ovarian cancer tissue. Furthermore ,we employed in vitro adhesion test to detect the alteration of ovarian cancer cell adhesion ability to ECM molecular like fibronectin ,collagen I and laminin after fluctuation of MYC and ITGB1 expression; Transwell assay was applied to check the invasion ability variation with the disturbance of MYC and ITGB1 level. Results The mRNA levels of MYC and ITGB1 were dramatically inverse-correlated in NCI-60 cells bank(P<0.01);The protein levels of MYC and ITGB1 in ovarian cancer cell lines were also negative correlated; The primary ovarian cancer tissue showed lower expression of ITGB1 and higher expression of MYC,while the matched metastasis displayed the opposite outcome;Ovarian cancer cells reduced adhesive and invasive capacity in case of ITGB1 being down-regulated ,however, the adhesive and metastatic ability improved tremendously with elevation of ITGB1;Promoted adhesion and invasion ability and rise of ITGB1 expression were observed after downregulation of MYC,meanwhile,and inhibition of ITGB1 reversed the increasement of adhesion and invasion ability. Conclusions MYC,inversely-correlated with ITGB1 in ovarian cancer cells,inhibited ovarian cancer cells adhesion and invasion. Inhibition of MYC could lead to enhanced adhesion and invasion ability of ovarian cancer cells.

Objective To evaluate the effectiveness of single balloon enteroscopy (SBE) in diagno-sing of suspected lesions in small intestine. Methods Data of 23 patients with suspected small intestinal disease, who underwent SBE (Olympus) between February 2009 and August 2009, were retrospectively studied. A total of 34 procedures were performed in 23 patients. The indications for the examination were suspected obscure gastrointestinal bleeding (n = 9), abdominal pain (n = 7), suspected intestinal tumor re-vealed by capsule endoscopy (n = 4), and Crohn disease (n = 3). Results The average preparation time of SBE was less than 5 minutes. The mean procedure time was 61±25 minutes and 67±28 minutes for the oral and anal routes, respectively. Examination of whole length of small intestine was achieved in 6 patients. The diagnostic rate of small-intestinal lesions was 60. 9%, and no severe complications including perforation occurred. Conclusion SBE is safe and easy to prepare and perform, which can be a useful diagnostic and therapeutic tool for suspected small bowel disease.

Objective To study the immediate conservative breast surgical reconstruction by trans-ferring the same lateral latissimus dorsal myocutaneous flap (LDM) for the treatment of stage Ⅱ and stage Ⅲ breast cancer, combined with neoadjuvant chemotherapy. Methods Breast cancer patients in stage Ⅱ and Ⅲ with pathological diagnosis by core needle biopsy, had undergone immediate conservative breast reconstruction surgery with transferring the latissimus dorsal myocutaneous (LDM). We scored the reconstructed breast twice at one month after operation and completion of radiation. The final score was decided using the mean value of the twice evaluating score. Kaplan-Meier survival was used to analyze the survival of 18 cases with traditional mastectomy. Results The tumor size ranged from 30 mm to 55 mm before neoadjuvant chemotherapy, and ranged from 25mm to 45 mm after neoadjuvant chemotherapy. The median weight of the tumor specimens in breast conservative operation was 140 g (90 g to 220 g). A-mong the 18 patients, 16 cases had more than 3 scores with satisfied cosmetics (93.33 % ). Dorsal subcu-taneous seroma in donation area was observed in 5 of 18 patients (27.78 %) and dorsal incision dehiscence was observed in 2 of 18 patients (11.11%). None of the patients developed recurrence except that 1 pa-tient (5.55 %) had distance metastasis (bone metastasis} in a mean 22-months follow-up. The Kaplan-Meier survival curve in breast conservation reconstruction patients had no different from that of traditional mastectomy patients at the same time. Conclusions Immediate conservative breast surgical reconstruction by using the same lateral latissimus dorsal myocutaneous flap is an effective method for stage Ⅱ and stage Ⅲ breast cancer patients combined with neoadjuvant chemotherapy, which can increase satisfactory breast so that cosmetic outcome can be reached.
