Objective To explore the efficacy difference of biliary stent combined with 125I seed intracavity irradiation and palliative biliary drainage in the treatment of obstructive jaundice caused by pancreatic head cancer. Methods The clinic date of 95 patients with pancreatic head cancer who underwent palliative surgery from June 2010 to June 2015 were analyzed retrospectively. 46 of the cases were treated with percutaneous biliary metal stent implantation combined with 125I seed intracavity irradiation (stent group), and the other 49 cases were treated with palliative biliary enterostomy (surgery group). The levels of jaundice, liver function, tumor size, survival time and hospitalization cost were compared between the patients before and after treatment. Paired t-test was applied for statistical analysis. Results Both the two treatment coulel effectively relieve jaundice and improve liver function. The mean TBIL of surgery group and stent group was (29.4±9.6) and (21.0±8.0)μmol/L after three months treanment, (40.3±11.0) and (24.4±9.6)μmol/L after six months treatment, respectively. Tumor maximum diameter of the two groups were (37.9 ± 4.5) mm and (33.5 ± 6.0)mm after three months treatment, (45.9 ± 5.0) mm and (37.0 ± 6.5) mm after six months, respectively. Each time point between them had statistical significance (t=-4.235,-5.476,-3.654,-6.702, P<0.05). The mean survival time was (12.83 ± 0.80) months in the stent group and (9.06±0.49) months in the surgery group, the difference was statistically significant (t=-3.49, P<0.01). The mean hospitalization cost of the stent group was (38 453.0 ± 7 282.0) yuan and the surgery group was (43 057.0 ± 7 667.4) yuan, the difference was statistically significant (t= 2.759, P<0.05). Conclusion For inoperable pancreatic head cancer patients, compared with palliative biliary enteric drainage, percutaneous biliary stent placement combined with 125I seed intracavity irradiation can effectively relieve biliary obstruction, improve liver function, inhibit tumor growth and prolong survival time.

Objective To investigate the dose and time kinetics of induction of apoptosis induced by doxorubicin in J urkat leukemiacells, and to explore its pertinent molecular mechanisms. Methods Human Jurkat leukemia T - cells were treated with doxorubicin at theconcentration of 0.1 mg/L, 0.2 mg/L, 0.5 mg/L and 1.0 mg/L for 6,12,24 and 36 hours, respectively, of which one sample was pre-treated with zVAD- fmk (benzyloxycarbonyl - Val -Ala - Asp - fluoromethylketone) prior to addition of doxorubicin 0.2 mg/L. Apop-tosis was detected with both annexin V - FITC and propidium iodide ( PI ) staining and annexin V FITC and PI double positive cellswere analyzed by flow cytometry. Western blot was used to evaluate the level of Fas ligand (FasL) and FADD (Fas - associated death do-main) expression. Results The differences of apoptotic cells induced by all dose of doxorubicin were not significant (P＞0.05 ) at 6hour;at 12 hour, only the highest dose, 1 mg/L, significantly induced cell apoptosis;while the lowest dose,0.1 mg/L, did not significantlycaused cell apoptosis for all time points. After exposure to the doses of 0.2 and 0.5 mg/L for 24 or 36 hours,a significant increase in per-centage of apoptotic cells was observed (P ＜ 0.001 ). Apoptosis induced by doxorubicin was completely inhibited when the cells were incu-bated with doxorubicin in the presence of zVAD - fmk (P ＜ 0. 001 ). The level of FasL and FADD expression correspondingly increasedwith exposure time to doxorubicin. Conclusions Doxorubicin induces apoptosis in a dose - and time - dependent manner; upregulatedFasL may initiate the activation of the Fas signaling pathway and caspases are the ultimate executioner in the induction of leukemia cellapoptosis by doxorubicin.

0.05) at 6 hour;at 12 hour,only the highest dose,1 mg/L,significantly induced cell apoptosis;while the lowest dose,0.1 mg/L,did not significantly caused cell apoptosis for all time points.After exposure to the doses of 0.2 and 0.5 mg/L for 24 or 36 hours,a significant increase in percentage of apoptotic cells was observed(P

OBJECTIVETo observe the correlation between constitution of yin deficiency syndrome (YDS) and polymorphism of HLA-DQA1/treatment response of Peg-lFNalpha therapy in HBeAg positive chronic hepatitis B (CHB) patients, and to explore constitution of Chinese medicine (CM) in response of interferon therapy.

METHODSTotally 120 HBeAg positive CHB patients who were treated with Peg-IFNalpha were enrolled, and assigned to YDS group (59 cases) and non-YDS group (61 cases) according to classification of CM constitutions. All patients were subcutaneously injected with Peg-IFNalpha-2b (1.0 microg/kg body weight) or Peg-IFNalpha-2a (180 microg), once per week. Effective efficacy was primarily judged when complete response (CR) or partial response (PR) was obtained at month 6. Those with CR or PR completed 1 year therapeutic course. HLA-DQA1 gene types were detected by polymerase chain reaction sequence specific primers (PCR-SSP). The distribution difference of CM constitutions in patients with CR or PR and their inter-group HLA-DQA1 allele frequency were compared.

RESULTSDifferent treatment responses of Peg-IFNalpha were observed in CHB patients of two different CM constitutions. The ratio of CR + PR was 61.0% (36/59) in YDS group, obviously lower than that in NYDS group [78.7% (48/61), P < 0. 05]. Patients with CR had a lower allele frequency of HLA-DQA1 * 0501 than those with no-response [14.8% (8/54) vs. 30.6% (22/72)] with statistical difference (P < 0.05). Patients with CR had a higher allele frequency of HLA-DQA1 * 0601 than those with no-response [18.5% (10/54) vs. 5.6% (4/72)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0301 was lower in YDS group than in non-YDS group [2. 5% (3/118) vs. 9.8% (12/122)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0501 was higher in YDS group than in non-YDS group [33.9% (40/118) vs. 18.9% (23/122)] with statistical difference (P < 0.05). Yet statistical significance was lost after adjustment (Pc > 0.05 for both).

CONCLUSIONSBoth constitutions of CM and HLA-DQA1 gene polymorphism af- fect HBeAg positive CHB patients' response to Peg-INFalpha. Constitutions of YDS and HLA-DQA1 * 0501 was not favorable to response, their association needed to be further studied.
