Objective To investigate the effect of pegylated interferon combined thymopeptideenteric-coated tablets on CXCR3, CCR6 and serum IL-2 and soluble ligand in patients with chronic hepatitis.Methods 125 patients with chronic hepatitis B patients from June 2015 to June 2016 in our hospital were selected and divided into observation group 62 cases and control group 63 cases.The observation group was treated with pegylated interferon combined thymopeptideenteric-coated tablets, and the control group was treated with thymopeptideenteric-coated tablets, the expression of T cells in patients with CXCR3 and CCR6 was detected by flow cytometry, the serum levels of interleukin-2 and soluble interleukin-2 receptorwere measured by enzyme-linked immunosorbent assay, and compared the treatment of two groups of patients.Results After treatment, the levels of IL-2 and sIL-2R in the observation groupwere (16.4 ±5.6), (9.4 ±2.1), significantly lower than that in the control group, while CXCR3 and CCR6 were (5.8 ±0.9), (5.54 ±1.2), significantly higher than the control group, the difference was statistically significant (P<0.05), the levels of HBsAg, HBeAg and HBV-DNA in the observation group were (1.5 ±0.4), (1.6 ±0.9), (1.6 ±0.3), significantly lower than those in the control group, the difference was statistically significant (P<0.05), the levels of ALT, AST, TBIL, IBIL in the observation groupwere (34.5 ±8.7), (31.4 ±6.9), (14.6 ± 6.9), (9.4 ±2.9), significantly lower than those in the control group, the difference was statistically significant (P<0.05).Conclusion Interferon combined thymopeptideenteric-coated tablets therapy for chronic hepatitis B is helpful to improve the level of chemokine receptor and inhibit the degree of inflammatory reaction.It can help to improve liver function and inhibit viral replication in patients with hepatitis B.It is better than the treatment of chronic hepatitis with thymosin alone.

Objective To study the effect of angelica polysaccharides (APS) on recoverable ability from cryopreservation damage of umbilical cord blood (UCB) hematopoietic cells and APS with hematopoietic growth factors (HGFs) on in vitro expansion of UCB mononuclear cells (MNC) after thawing. Methods Thawed UCB MNC were cultured 24 h or 14 d with various concentration of APS (0,50,100,200,and 400 ?g/mL) or with APS and HGFs. The MNC counting assay,typan blue exclusion assay,colorimetric MTT assay for cell proliferation,CFU-Mix colong-forming assay,and flow cytometry for CD34+ cell rate were detected. Results After adding certain concentration APS in thawed UCB cells,the number of MNC,the rate of trypan blue exclusion,the proliferation of MNC,and the colony production of CFU-Mix were significantly enhanced (P

Objectives:To study the preparation techniques of gelatin microspheres encapsulated with sodium fluoride and evaluate the anticaries functions in dental plaque model in vitro. Methods:Fluoride gelatin microspheres were prepared by emulsion polymerisation method. The encapsulation rate and drug contents were tested by ISE. In vitro inhibition of demineralization were also examined. Results:The mean size of fluoride GMS was (16.81?8.77)?m.The encapsulation rate was 76.73%.The drug content was 5.61%.The release profile in vitro showed sustained effects. Fluoride GMS can prevent demineralization more efficiently. Conclusions:Fluoride gelatin microspheres may be an promising topical fluoride release system.

Objective To summarize the experience of nursing cancer patients with Wernicke encephalopathy (WE) after gastrointestinal surgery. Method The clinical data of 6 patients with WE after gastrointestinal surgery in our hospital from January 2005 to June 2015 were retrospectively analyzed to summarize the nursing strategies. Results All the 6 patients showed mental changes of different types, 5 patients developed with ocular manifestations and one patient with ataxia. Only one patient showed the classic triad of the disease at clinical presentation. All the 6 patients had characteristic manifestations on cranial MRI and received thiamine (vitamin B1) at diagnosis. Four patients were completely recovered and 2 were partially recovered. Conclusion Timely sufficient thiamine supplementation during the perioperative period is the key to prevent and treat WE in the patients with gastrointestinal cancer. Careful observation of the patients′ mental state and the effective nursing for the special classic triad of the disease are critical for a better prognosis.

Objective:In order to obtain safer HBV DNA vaccine,recombinant kanamycin resistance eukaryotic expression plasmid containing the gene of HBV surface antigen was constructed and used to study humoral immune response in BALB/c mice.Methods:HBV antigen middle protein(preS2+S) encoding gene fragment was isolated from the recombinant eukaryotic expression plasmid pcDNA-S 2S;subcloned into eukaryotic expression vector pVAX1.After confirmed the presence of the gene by restriction endonuclease analysis,it was used to immunize the healthy BALB/c mice at different doses,and the levels of anti-HBs in serum was determined by ELISA.Results:Restriction endonuclease analysis confirmed recombinant plasmid pVAX-S 2S was what was expected.Serum anti-HBs was detected at the 2nd week after DNA vaccination at all three doses(100 ?g,50 ?g,10 ?g per mice)and their titers were increased with time.Quantitative comparison of the serum anti-HBs levels revealed significant(P

The resident match system established in 1952.And since then almost all of the senior medical students and international students have applied a position of resident training in this national system.They seek a respective resident program and hospital for training while the hospital hires students they preferred.The match procedure includes submitting application,interview of selected candidates,submitting rank-order list of both parties,centralizing matching service by computer and announcement of the results in Match Day.This is a relatively stan-dardized,rational and fair system which we can learn something from.
