ABSTRACT
Objective: To observe the effects of RuanJianXiaoYing Granule on the expressions of specific transcription factors and cytokines of Treg and Th17 in the Hashimoto thyroiditis (HT) rats with liver depression and spleen deficiency, and to investigate the therapeutic effect of RuanJianXiaoYing Granule on HT and its immunological mechanism. Methods: A total of 48 SD rats were randomly divided into normal group (12 rats) and modeling group (36 rats). The HT model was established by subcutaneous injection of excessive iodine drinking water and thyroglobulin, and then combined with chronic restraint stress, excessive fatigue and dietary disorders to prepare the rat models with liver depression and spleen deficiency. After modeling, the rats were randomly divided into model group (n=12), Tripterygium wilfordii group (n=12), and RuanJianXiaoYing group (n=12), and the rats were treated for 8 weeks. In addition to the dead rats and unqualified specimens during the experiment, the test results of 10 rats in each group were retained. The general situation of the rats in various groups was observed; the abdominal aortic blood and thyroid gland tissue of the rats in various groups were collected after the last administration; the levels of thyroglobulin antibody (TGAb), thyroid peroxidase antibody (TPOAb), free triiodothyronine (FT3), free thyroxine (FT4), thyrotropin-releasing hormone (TRH) and thyrotropin (TSH) in serum and the levels of IL-17, IL-23 and IL-10 were detected by ELISA method; the pathomorphology of thyroid gland tissue of the rats in various groups were detected by HE staining; the expression levels of Foxp3 and RORyt proteins in thyroid gland tissue of the rats in various groups were detected by Western blotting method. Results: Compared with normal group, the levels of serum TGAb and TPOAb of the rats in model group, Tripterygium wilfordii group and RuanJianXiaoYing - group were increased (P0. 05); the level of serum IL-10 was increased (P<0. 05), and the levels of serum IL-17 and IL-23 were decreased (P<0. 05). The follicular cavity of thyroid gland in normal group had regular morphology, complete structure and no lymphocyte infiltration. In model group, the follicular cavity of thyroid gland was enlarged, the follicular structure was destroyed, and a large number of lymphocyte infiltration was observed in and around the follicular cavity. In Tripterygium wilfordii group, the follicular cavity of thyroid gland was enlarged, part of the follicular structure was destroyed, and there was a small amount of lymphocyte infiltration in and around the follicular cavity, which was less than that in model group. The morphological changes of thyroid gland in RuanJianXiaoYing group were similar to those in Tripterygium wilfordii group Conclusion: RuanJianXiaoYing Granule has the therapeutic effect in the HT rats with liver depression and spleen deficiency by regulating the expressions of the specific transcription factors Foxp3 and RORγt protein and related cytokines of Treg and Th17.

ABSTRACT
Objective To investigate the risk factors for gastrointestinal polyps.Methods A retrospective analysis was performed.The patients who undergone gastrointestinal endoscopy and diagnosis gastric polyps were selected who hospitaled in the Navy General Hospital from January 2012 to January 2014 and divided into cases group(patients with gastric polyps and colonic polyps) and control group (patients with gastric polyps).The information was recorded.Results The case of over 60 years of age distribution in case group was significantly higher than the control group.Single factor analysis showed that the indices including age,HP infection,smoking,drinking,high cholesterol and hypertension were significantly different from that of control group (x2 =11.538,9.350,4.190,5.103,8.992,4.038;P ＜ 0.05) after adjusting the interactions of the factors.Multi factor Logistic analysis showed that the risk of gastrointestinal polyps was significantly related with sex,age over 60 years old,HP infection,diabetes,smoking,drinking and hyperlipoidemia(P＜0.05),and the OR value from small to large were age,HP infection,alcohol drinking,hyperlipidemia,smoking,diabetes and gender.Conclusion The female gastric polyp patients who were over 60 years old,HP infection positive,diabetes,hyperlipidemia,smoking,drinking are more likely to suffer from intestinal polyps,and they were suggested to perform colonoscopy.Among them,women with HP positive infection and the age over 60 are high risk population.If they complicated with hyperlipidemia,they should had a screening for colorectal carcinoma in situ.
ABSTRACT
Objective To investigate the incidence and influencing factors for sharp injuries occurred in workers in central sterile supply departments (CSSDs).Methods In October-November 2012,a multicenter cross-sectional survey was conducted,a total of 95 workers in CSSDs of 16 hospitals in Hunan Province were surveyed through questionnaires.Results A total of 89 workers (93.68%)in CSSDs sustained sharp injuries,46 (48.42%)of whom sustained 1 -5 times of sharp injuries,22(23.16%)sustained 6-10 times of sharp injuries,and 11 (11 .58%)sus-tained for at least 10 times of sharp injuries.81 workers (85.26%)sustained at least one time of sharp injuries one year before survey,52 (54.73%)of whom were injured by contaminated needles or other sharps.Logistic regression analysis revealed that higher educational background was protective factor for sharp injuries(OR 90%CI :0.05-0.87);while poor sleep quality(OR 90%CI :1 .03-17.94),frequent touching sharps(OR 90%CI :1 .11 -12.15),and irrational placing of objects by the other medical stuff (surgeons and nurses in operating rooms)(OR 90%CI :1 .23-16.98)were the risk factors for sharp injuries.Conclusion The incidence of sharp injuries among workers in CSSDs is high,which is related to personal factors and environmental factors.It is suggested to strengthen staff training to enhance their awareness of precaution.
ABSTRACT
The protective efficacy of DNA plasmids encoding avian infectious bronchitis virus (IBV) S1, N, or M protein was investigated in chickens. Chickens were inoculated monovalently (with plasmid pVAX1-16S1, pVAX1-16M, or pVAX1-16N alone) or multivalently (combination of the three different plasmids, pVAX1-16S1/M/N). A prime-boost immunization protocol against IBV was developed. Chickens were immunized with the multivalent DNA vaccine twice and then boosted with an inactivated vaccine once. Antibody titers of the chickens immunized with pVAX1-16S1/M/N were much higher than those of the monovalent groups (p < 0.01). A protective rate up to 90% was observed in the pVAX1-16S1/M/N group. The serum antibody titers in the prime-boost birds were significantly higher than those of the multivalent DNA vaccine group (p < 0.01) but not significantly different compared to the inactivated vaccine group at 49 days of age. Additionally, the prime-boost group also showed the highest level of IBV-specific cellular proliferation compared to the monovalent groups (p < 0.01) but no significant difference was found compared to the multivalent DNA vaccine group, and the prime-boost group completely protected from followed viral challenge.
