Objective To observe the efficacy and toxicity of 5 -Fluorouracil plus cisplatin (FP)and docetaxel plus cisplatin(DP)in the treatment of patients with metastatic esophageal cancer.Methods A total num-ber of 68 cases of metastatic esophageal cancer confirmed by histopathology and (or)cytological examination was ana-lyzed retrospectively.There were 33 cases in FP group(5 -Fu 500mg/m2 ,d1 -5;DDP 20mg/m2 ,d1 -5,28 days a cycle),and 35 cases were in DP group(DTX 75mg/m2 ,d1,DDP 20mg/m2 ,d1 -3,21 days a cycle).The evaluation of efficacy and toxicity were performed on all patients per 2 cycles.Statistics and analysis of the difference between the two groups was performed.Results For FP group,CR was in 1 case,PR ere in 12 cases,SD ere in 16 cases and PD ere in 4 cases,respectively.The corresponding value was 3,18,11 and 3 for DP group.The objective response rate (ORR)for DP group(68.57%)was significantly higher than FP group(36.39%)(χ2 =5.83,P =0.02),and the disease control rate (DCR)were similar with no significance between the two groups(P =0.71).The Ⅲ -Ⅳ degree myelotoxicity for DP group was higher than for FP group with statistical difference (χ2 =7.07,P =0.01),while the incidence of nausea,vomiting,diarrhea and liver toxicity was similar (P >0.05).Conclusion DP regimen was more effective than FP regimen for the metastatic esophageal cancer,and the patients can tolerate with the slightly higher incidence of myelotoxicity,it was worthy of further study and clinical application.

Objective To investigate the efficacy of the combination ofJiangtang decoction and insulin in the treatment of type 1 diabetes mellitus in children.Methods A total of 43 children with type 1 diabetes mellitus were enrolled and randomly allocated to either a insulin group (control group) and a insulin plusJiangtang decoction group (treatment group) using the table of random digits, with 23 patients in the control group and 20 in the treatment group. The patients in the control group were treated with insulin, and those in the treatment group were administrated withJiangtangdecoction on the basis of the treatment in the control group for 2 months. Body mass index (BMI), fasting plasma glucose (FPG), postprandial blood glucose (PBG) and hemoglobin A1c (HbA1c) were measured.Results The levels of FPG, PBG and HbA1c were significantly decreased in the treatment group (twere 3.376, 54.493, and 2.798, respectively; allP<0.01), and the PBG level was significantly decreased in the control group (t=29.714,P=0.000). The levels of FPG, PBG and HbA1c in the treatment group were significantly lower than those in the control group (twere 2.715, 2.191 and 5.627, respectively;P<0.05 orP<0.01). There was no difference in BMI between the treatment group and the control group (t=0.159,P=0.874). The proportion of patients with HbA1c <7.5% in the treatment group (60.0%, 12/20) was higher than that in the control group (26.1%, 6/23;χ2=5.055,P=0.025).Conclusion Combination ofJiangtang decoction and insulin can decrease the level of FPG, PBG and HbAlc, and its therapeutic effect is superior to insulin alone for type 1 diabetes in children.

BACKGROUND:Studies have demonstrated that chitosan can indirectly promote the proliferation of fibroblast and the synthesis of collagen, Using chitosan and specific fibroblasts together to construct tissue-engineering materials for tendon repair may be an adequate way to promote healing and prevent adhesion during the healing process.OBJECTIVE: To observe the effect of water soluble chitosan (WSC) on the growth and genotype of 3T3TK fibroblasts.DESIGN: Controlled experiment based on observation.SETTING: Jiujiang University Medical College.MATERIALS: 3T3TK fibroblasts were provided by Cell Bank of Chinese Academy of Sciences. WSC (specification: 60 mesh, 30CPS, Jinan Haidebei Marine Bioengineering Co.,Ltd),DMEM (low sugar) (Gibco Company, USA), fetal bovine serum (FBS, Sijiqing Biological Engineering Institute, Hangzhou), penicillin, streptomycin (Biosharp Company, USA),trypsin (BioEev-Tech Scientific & Technical Co.,Ltd, Beijing).METHODS: This experiment was carried out in the Laboratory for Clinical Application of Biology, Center for Medial Scientific Research, Jiujiang University between November 2004 and April 2006. ①Cells in the log phase were digested with 2.5 g/L trypsin to produce single cell suspension and inoculated into a 96-well culture plate at a density of 6 000 cells /200 μL medium. Five groups were prepared, 5 holes per group. 200 μL cell suspension was added into each well.After 24 hours of cultivation, supernatant was discarded, 200 μL DMEM with 1, 0.1, 0.01 and 0.000 1 g/L chitosan was added respectively in the first four groups. The remaining group was taken as the negative control group, in which 200 μL DMEM medium without chitosan was added. The cell suspension was routinely cultured for 72 hours. The cell viability was measured by CellTilter- GloTM Luminescent Cell Viability Assay according to the manufacturer's protocol. Cells in the log phase were split and inoculated into 24-well culture plates. Four groups were prepared (5 holes per group). 1 mL DMEM medium supplemented with 1, 0.1, 0.01 g/L chitosan was added into the first 3 groups respectively, and the 4th group was set as control group. Hydroxyproline and alkaline phosphatase(ALP) kits were used for detecting the contents of collagen and ALP in the supernatant of fibroblasts.MAIN OUTCOME MEASURES : ①Effect of WSC on viability of fibroblasts cultured in vitro.②Contents of collagen and ALP in the cell culture supernatant of fibroblasts.RESULTS:①Detection results of viability of fibroblasts: There were no significant differences in viability of fibroblasts between each chitosan group and control group (P ＞ 0.05).②Contents of collagen and ALP in the cell culture supernatant of fibroblasts: Hydroxyproline content in the cell culture supernatant of fibroblasts of 1 g/L and 0.1 g/L groups was (7.598±0.770) and (8.366±0.308)mg/L, respectively, which was higher than that of control group [(11.269±0.707)mg/L,P ＜ 0.01]; Collagen content in the 1 g/L and 0.1 g/L groups was(56.703±5.748) and(62.437±2.301)mg/L, respectively, which was lower than that of control group [(84.099±5.280)mg/L,P ＜ 0.01]. With the concentration of chitosan increasing, the collagen content was decreased in a dose-dependent manner. There were no significant differences in ALP activity in the cell culture supernatant between each chitosan group and control group (P ＞0.05).CONCLUSION: WSC does not obviously inhibit the viability of 3T3TK fibroblasts, but can markedly reduce the content of secreted collagen. It is indicated that chitosan can be used as tissue engineering material for tendon repair, and inhibit adhesion formation during tendon repair.

BACKGROUND: Looking for effective measures to ensure the survival of the implanted stem cells against ischemia-induced hypoxia becomes the major concern in the research of cell transplantation therapy for cerebral infarction.OBJECTIVE: To study the effects of human Persephin gene transfer on hypoxia-induced apoptosis of neural stem cells.DESTGN: A randomized controlled basic study on cells.SETTTNG: Department of Neurology, the Second Affiliated Hospital of Sun Yat-sen University.MATERTALS: This study was completed in the Lin Baixing Laboratory Center of the Second Affiliated Hospital of Sun Yat-sen University from July to December in 2006. Recombinant adenovirus pAdCMV persephin was constructed in our lab. C17.2 neural stem cells were kindly provided by Prof. Snyder, Harvard Medical University, USA. Trypsin and DMEM/F12 were purchased from Gibco Company (USA), fetal bovine serum (FBS) from Sijiqing Biological Engineering Materials Co. Ltd (Hangzhou, China); Poly-lysine from Sigma Company (USA), TUNEL assay kit and FuGENE kit from Roche Molecular Biochemicals Company (Swiss), and S-P immunohistochemical detection kit and DAB reaction kit from Mycine Biological Engineering Company (Fujian). Rat anti-human monoclonal Nestin antibody and rabbit anti-human polyclonal persephin antibody were manufactured by Santa Cruz Company (USA), and persephin anti-senseoligodeoxynucleotide (ODN) was synthesized by Shanghai Biological Engineering Company.METHODS: ① Interventions: C17.2 neural stem cells cultured in vitro were infected by recombinant adenovirus containing persephin gene, and they were divided into four groups: blank control group (Group A, in which the C17.2 neural stem cells were not treated with hypoxia), hypoxic group [Group B, in which the cells were cultured at 37 ℃ in anaerobic incubation containing N2 (0.95 in volume fraction) and CO2 (0.05 in volume fraction)], hypoxia + pAdCMV persephin infection group [Group C, where the cells were cultured under the conditions as in group B after pAdCMV persephin infection for 48 hours], and hypoxia + pAdCMV persephin infection + anti-sense persephin ODN group (Group D, where the cells were infected by pAdCMV persephin and anti-sense persephin ODN. ② Evaluation: The expression of Persephin protein was analyzed using Western blotting; Apoptotic index was detected with terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end-labeling (TUNEL) assay; The changes of apoptotic rate was determined with flow cytometry.MAIN OUTCOME MEASURES: Expression of Persephin protein; Apoptotic index; Apoptotic rate.RESULTS: ① Expression of Persephin protein: A specific band (relative molecular mass of 24 000) was detected by Western blotting in pAdCMV persephin infected cells, suggesting the successful expression of persephin gene.Interestingly, the cells infected with both pAdCMV persephin and anti-sense persephin ODN also showed the specific band of about 24 000, but with much less density, indicating that anti-sense persephin ODN could effectively inhibit the expression of pAdCMV persephin. However, this band was not presented in the blank control groups. ② Apoptotic index:The apoptotic index in group C was significantly lower than those in groups B and D (P＜0.01), but still higher than that of group A (P＜0.01), suggesting that persephin gene transfer could attenuate apoptosis to some extent. ③ Apoptotic rate: The apoptotic rate in groups B and D were obviously higher than that in group A (P ＜ 0.01), and it was lower in group C than in groups B and D (P＜0.01).CONCLUSION:Recombinant adenovirus can efficiently mediate Persephin gene transfer into C17.2 neural stem cells,resulting in high expression of the exogenous Persephin in vitro, which effectively reduces C17.2 neural stem cell apoptosis induced by hypoxia.

Objective To preliminarily explore the expresssion of the Hedgehog signaling pathway (HH) after different liver trauma, and provide basis for the blockaded effection of HH and the potentiality of new traditional Chinese medicine exploition. Methods After adaptive breeding for one week, a cohort of 140 male SPF Fisher 344 rats were randomly divided into Retrorsine injection (R) indicated the toxical of chemical damage of liver, partial hepatectomy (PH) indicated the acute liver trauma, retrorsine/partial hepatectomy (R/PH) for the hepatic stem cells regeneration, and normal control (N) groups. The administering of retrorsine or placebo, and PH or sham operation were performed as Gordon’s matheds. RT-PCR, real-time PCR and immunohistochemistry were performed to detect the expression of the constituents related to HH after liver damage. Results RT-PCR demonstrated that the mRNA expression of IHH, PTCH, Smo, Gli1, Gli2, Gli3 were all activated in primary liver cells after different kinds of liver damage. The results of real-time PCR analysis indicated an interaction effect existing between the treatment and the time in 3 Hedgehog-related constituents (signaling molecule IHH, indicators of the HH activation Ptc, Gli1) (all P<0.001). The protein expression of PTCH in liver tissue section was confirmed by immunohistochemistry, which differed in the duration in PH and R/PH groups. Conclusion The HH was abnormally activated during the different liver trauma. It’s maybe an important signaling pathway during the liver’s reaction after damage.
