Objective To investigate the effects of baicalin on the apoptosis and cell migration of intestinal epithelial cells 6 (IEC-6) induced by lipopolysaccharide (LPS) . Methods LPS was adopted to establish LPS-induced cells injury model. Methyl thiazolyl tetrazolium ( MTT) assay and Elisa kits were used to evaluate the effect of LPS on the tumor necrosis factor alpha ( TNF-α) and interleukin 6 ( IL-6) concentrations of IEC-6. Hoechst 33258 staining and flow cytometry were used to evaluate the effect of baicalin ( in the dosage of 2.5, 5.0, 10.0 μg/mL ) on the cell apoptosis. Cell migration was observed and calculated on a wounding model of IEC-6 cells induced by a pipette tip. Results Compared with the control group, the survival rate of IEC-6 in 1.0 μg·mL-1 LPS group was much lowered, TNF-α and IL-6 concentrations were significantly increased, the apoptotic rate of IEC-6 was increased and the cell migration activity was significantly decreased ( P<0.05) . Compared with the model group, IEC-6 apoptosis was relieved to various degrees in baicalin groups, the apoptotic rate of IEC-6 was obviously decreased (P<0.05) and cell migration activity was increased significantly (P<0.01) in 10.0 μg·mL-1 baicalin group. Conclusion Baicalin has the capacity of protecting IEC-6 from LPS-induced injury and increasing cell migration activity.

OBJECTIVETo explore the inhibition of Jumi (traditional Chinese medicine) extraction on the growth of human cervical cancer cell line HeLa.
METHODSNude mouse model of human cervical cancer HeLa cell transplantation was established. The nude mice bearing cancer were randomly divided into control group and Jumi treated groups with different concentration (0.001, 0.002, 0.005, 0.01 mg/ml). The growth of cervical cancer cell in experimental mice were measured. Cultured HeLa cells were incubated in culture media with or without Jumi extract for 48 hours. Cell proliferation rate, cell apoptosis, caspase-3/7 and caspase-6 activity were determined by MTT colorimetric assay, flow cytometry analysis and spectrophotometric detection, respectively.
RESULTSWith the increase of the concentration of Jumi extract, tumor-bearing mice tumor inhibition rate gradually increased. The proliferation of cultured HeLa cells were significantly inhibited by Jumi extract in a dose-dependent manner. IC50 was 0.004 mg/ml. Apoptosis rates in the cells treated with Jumi extract were higher than those of the control group. Compared with the control group, except for lower Jumi treated group (0.001 mg/ml), caspase-3/7 and caspase-6 activity were significantly increased in the all Jumi treated groups.
CONCLUSIONJumi extract can inhibit the proliferation of human cervical cancer cell line HeLa in vitro in a dose-dependent manner and promote cell apoptosis through caspase-3, caspase-7 and caspase-6 pathway.

AIM: To examine the relationship between corneal lymphangiogenesis and hemangiogenesis after keratoplasty.METHODS: Nineteen human corneas were obtained from 19 patients undergoing a second corneal transplantation in Zhongshan Ophthalmic Center in 2005. Blood and lymphatic vessels in human transplanted corneas were identified by lymphatic vessel endothelial receptor(LYVE-1) and platelet endothelial cell adhesion modecule-1(PECAM-1) immunohistochemistry, and double enzyme-histochemistry; then the association of corneal blood vessel counting (BVC) with lymphatic vessel counting (LVC) was examined.RESULTS: Corneal hemangiogenesis was present in 12 cases (63%), and lymphangiogenesis occurred in 5 cases (26%) of human transplanted corneas. In addition, corneal lymphangiogenesis was only present in vascularized corneas. LVC was strongly and positively correlated with BVC(r=0.725;P<0.01).CONCLUSION: Corneal lymphangiogenesis develops after keratoplasty, and strongly associates with hemangiogenesis.

OBJECTIVE:
To explore the application of a 289bp fragment of the 16S rDNA gene to identify various species of sarcosaphagous Calliphorid flies.
METHODS:
Twenty-six Calliphorid flies were collected from 14 Chinese provinces. All specimens were properly assigned into three genera and six species. The DNA of the pectoralis was extracted using CTAB method. Then PCR amplification was done for the 289 bp fragment of the 16S rDNA gene. The PCR products were then purified and sequenced, and the obtained sequences were uploaded to GenBank. The phylogenetic tree was built by the neighbor-joining method and intraspecific and interspecific divergences were calculated by sequence analysis.
RESULTS:
The above 26 sarcosaphagous flies could be well clustered according to different genera and species. The evolutional intraspecific values were all zero, the evolutional interspecific variations varied from 0.3% to 6.5%.
CONCLUSION
The 289 bp fragment of the 16S rDNA of sarcosaphagous flies can be effectively used to identify most of the flies at species level. This method appears to be fast and low dissipative, which might be used to estimate postmortem interval by sarcosaphagous flies.

ObjectiveTo investigate the effect of Jingangwan on the expression of osteoclast, c-Jun N-terminal kinase(JNK), p38 mitogen-activated protein kinase(p38 MAPK), and interleukin-1(IL-1) in the osteoporosis model rats, explore the mechanism of Jingangwan in the treatment of osteoporosis, and determine the optimal dosing concentration of Jingangwan. MethodFifty-six rats of SPF grade were randomized into a blank group,a sham operation group,a model group, model group,high-, medium-, and low-dose Jingangwan groups (0.72, 0.36, 0.18 g·kg-1·d-1, ig),and an estradiol valerate group (0.009 g·kg-1·d-1, ig), with eight rats in each group. The rats in the model group, the blank group, and the sham operation group received 3 mL of normal saline, respectively. Samples were collected 12 weeks after drug administration. The number of osteoclasts was observed by tartrate-resistant acid phosphatase (TRAP) staining. Serum levels of JNK, p38 MAPK, and IL-1 were detected by enzyme-linked immunosorbent assay (ELISA). The mRNA expression levels of p38 MAPK and JNK were detected by real-time quantitative polymerase chain reaction (Real-time PCR). ResultThe TRAP staining results showed that compared with the model group, the estradiol valerate group and the Jingangwan groups could inhibit the formation of osteoclasts to different degrees. As revealed by ELISA results, compared with the model group and the sham operation group, the model group showed increased serum levels of p38 MAPK, JNK, and IL-1 (P<0.01), while compared with the model group, all the groups with drug intervention showed decreased levels of p38 MAPK, JNK, and IL-1 (P<0.01). The serum levels of JNK and IL-1 in the high-dose Jingangwan group were lower than those in the estradiol valerate group (P<0.05). Real-time PCR results showed that compared with the blank group, the model group showed increased relative mRNA expression of p38 MAPK and JNK in the thighbone (P<0.01), while compared with the model group, all the groups with drug intervention showed decreased relative mRNA expression of p38 MAPK and JNK in the thighbone (P<0.01). ConclusionJingangwan can inhibit the formation of osteoblasts,reduce the diameter of the bone marrow cavity,improve bone quality,suppress the production of inflammatory factors,affect the metabolism of the MAPK signaling pathway,and blunt p38 MAPK and JNK activities to inhibit the differentiation and proliferation of osteoblasts and regulate bone metabolism, thereby preventing osteoporosis. Therefore,Jingangwan may be of application value in maintaining bone health and treating osteoporosis.

OBJECTIVETo evaluate the clinical significance of 320-slice CT hepatic artery images in patients with liver transplantation.
METHODSA total of 58 patients underwent CT scanning by 320-slice scanner after liver transplantation. They were divided into 2 groups according to the concentration of contrast media as follows: Group A (27 cases, 350 mgI/ml iopromide), Group B (31 cases, 370 mgI/ml iopromide). Contrast medium was infused at 6 ml/s, with a total dose of 50 ml. Images were generated by dynamic volume scanning and were processed by 4D digital subtraction angiography (DSA) imaging software. The time-density curve (TDC) of the hepatic artery was delineated. The time to peak, peak contrast enhancement were recorded. The physiological parameters such as body weight and height were analyzed.
RESULTS(1) There were no differences in clinical parameters such as age, sex, height, weight, or BMI between groups. The time to peak of hepatic artery of group A and B was (19.71+/-3.11) s and (20.06+/-3.67) s, and had no significant difference. The maximum peak enhancement of hepatic artery in groups B was higher than that group A (P < 0.05). (2) 4D DSA revealed hepatic artery pseudo-aneurysm (n = 2), and hepatic artery mild stenosis (n = 13), moderate stenosis (n = 5), severe stenosis (n = 9) and occlusion (n = 1), segmental moderate and severe stenosis (n = 4), and compensatory circulation with hepatic artery severe stenosis and occlusion (n = 6). hepatoportal arteriovenous fistulas (HPAVF, n = 12), donor-recipient hepatic artery mismatch (n = 3). Hepatic arterial branch are decreased and opened in 15 cases and 8 cases.
CONCLUSION320-slice CT hepatic artery images is safe, noninvasive, and accurate technique to evaluate hepatic arterial complications after liver transplantation.
