Objective To screen immune molecules expressed on peripheral blood mononuclear cells (PBMCs) which arc related to the aggravation of chronc hepatitis B (CHB). Methods Real-time polymerase chain reaction (PCR) was employed to detect the relative expression of 39 immune molecules at mRNA level and then compare the differences between groups (control group, mild CHB group, moderate CHB group and severe CHB group). The investigated immune molecules included leukocyte differentiation antigens, chemokine receptors, apoptosis-related ligands and receptors,adhesion molecules and Toll like receptors. Scheffe model was used to compare the differences among all groups and Spearman rank correlation was used for correlation analysis. Results Among the 39 immune molecules, the expressions of tumor necrosis factor related apoptosis inducing ligand (TRAIL), TRAIL receptor (TRAIL-R) 2, CD64, CD30, CD27, CD28, L-selectin (CD62L),intercellular adhesion molecule-1 (ICAM-1), chemokine (C-X-C motif) receptor (CXCR) 2 were significantly increased in severe CHB group compared with those in control group ( 1.96, 2.13, 1.33,1.16, 1.57, 2.14, 2.03, 2. 10 and 2.09, respectively; all P＜0.05). The expressions of TRAIL,TRAIL-R2, CD64, CD30, CD27 were highly correlated with the expression of interferon gamma (IFN-γ) (r=0. 816, 0. 572, 0. 462, 0. 697 and 0. 793, respectively; all P＜0.01). The expressions of TRAIL-R2, CD64, CD30, CD62L, ICAM-1 were highly correlated with the expression of tumor necrosis factor alpha (TNF-α) (r=0. 494, 0. 588, 0. 568, 0. 968 and 0. 976, respectively; all P＜0.01). Conclusion The abnormal expression of TRAIL,TRAIL R2,CD64,CD30,CD27,CD28,CD62L,ICAM-1 and CXCR2 may play an important role in the pathogenesis and aggravatoin of hepatitis B.

Objective To investigate the effects of autologous blood transfusion and acute normovolemic hemodilution inflamma‐tory response in patients with spinal surgery .Methods 60 patients with spinal surgery ,were randomly divided into the control group ,autologous blood transfusion group ,acute normovolemic hemodilution group ,20 cases in each group .The control group in in‐traoperative bleeding time and blood input variants of inventory .Autologous blood transfusion group was used in combination with intraoperative autologous blood recovery unit ,lose banked blood hemoglobin was low .Acute normovolemic hemodilution group via peripheral vein input must first crystal liquid or gel liquid ,then through internal jugular vein slowly pulled out the body′s blood into the special bags containing anticoagulant ,swing machine through blood kept shaking ,input when appropriate .Preoperative(T1) , After surgery 2 h(T2) ,6 h(T3) ,12 h(T4) and 24 h(T5) blood at each time point 5 mL ,detect the WBC ,IL‐6 ,TNF‐α.Records with and without postoperative complications .Results WBC in autologous blood transfusion group and acute normovolemic he‐modilution group were higher than that of preoperative ,difference was statistically significant(P<0 .05);In T2 -T5 ,serum IL‐6 , TNF‐a and the WBC concentration compared with the basis of their respective value(T1) increased significantly ,but were signifi‐cantly lower than control group ,the difference was statistically significant(P< 0 .05) .Postoperative follow‐up of the autologous blood transfusion group and acute normovolemic hemodilution group and no complications .Conclusion The autologous blood trans‐fusion group and acute normovolemic hemodilution group could effectively reduce the intraoperative and postoperative systemic in‐flammatory response ,which obviously save blood resources .

Objective:To evaluate the quality condition and problems of acetylspiramycin at present. Methods:According to the standard described in Chinese Pharmacopoeia (2015 edition), acetylspiramycin and its preparations were determined, and the overall quality level of domestic acetylspiramycin was evaluated. The related substances, components and dissolution were analyzed to further explore the quality status. Results:In 258 batches of samples, the dissolution of only one batch did not meet the standard with the passing rate of 99. 6%. The results of exploratory research showed that the content of impurities in raw material was determined by the synthesis process, and the impurity profile of domestic and foreign formula was different. The dissolution behavior of domestic and for-eign formula in four kinds of media was not similar as well. Conclusion: The quality of domestic acetylspiramycin is promising. The research of related substances provides the reference for controlling the target impurities. The consistency assessment of dissolution pro-vides the reference for the formula process improvement and clinical application of acetylspiramycin tablets.

The model of vaginal candidiasis in Kunming mice was constructed in order to search for the optima construction conditions and provide an economic animal model of Candida albicans (C. albicans) vaginitis. Estrogen benzoate (E2) was given to mice at different concentrations ranging from 0.0 to 0.05 mg/mouse (4 levels) beginning 72 h prior to vaginal inoculation, then mice were inoculated intravaginally with various concentrations of stationary-phase C. albicans blastoconidia (ATCC90028) (5 levels) in 20 microL of phosphate-buffered saline (PBS) in each E2 level. General state, scores of genital pathology, the hyphae and vaginal fungal burden (CFU) in vaginal lavage fluid, the hydrops rate of uterus and vaginal tissues for pathological section in mice were observed and obtained at day 2, 4, 7, 14 and 21 after inoculation. The results showed the infection rate in mice was related to the dosage of E2 and concentration of C. albicans blastoconidia. Additionally there was better cross-effect between the two treated factors. The infection rate was about 80% on the day 4, and could reach 100% on the day 7 until the end of experiment after inoculated intravaginally in groups of E2I3, E2 0.025 mg/mouse injected hypodermically and inoculated intravaginally with 5 x 10(4) C. albicans blastoconidia, and large amount of hyphae and blastoconidia could be observe in superficial layer tissue and canal of vaginal by PAS. From the results in our experiment it was concluded that E2I3 was the optima construction condition in kunming mice.

Objective To explore the effect and mechanism of early using specific immune RNA (iRNA) for preventing burn infection.Method 129 patients with serious burn were randomly divided into two groups by double blind method. The control group (n=64) was treated with routine method; The therapeutic group(n= 65) was given specific iRNA in addition to the routine therapy. The incidence of infection in two groups were investigated; Meantime, with the methods of monoclonal antibody (McAb) APAAP, 3H- TdR incorporation and MTT colorimetery, the various immune functions of patients were determined. Result (1) the incidences of wound infection and bacteriemia after burn in the therapeutic group were markedly lower than those of the control group; (2) the therapeutic group was also superior to the control group in the general condition and time of the wound healing; (3) on the l0th day postburn, the various immune founction tested in the therapeutio group have approximately restored to the normal levels, while those in the control group were still in low levels. The difference between the two groups was statistically significant (P＜0.01). Conclusion Specific iRNA, which, when used early after burn, can reduce the incidence of postburn infection, and improve immune functions of burned patients.

Objective To investigate the relationship between thyroid carcinoma and psychosocial risk factors.Methods A hospital based case-controlled study of thyroid carcinoma was conducted.Cases were path-ologically confirmed as primary papillary thyroid carcinoma.Both 102 cases and 114 controls were tested by the PSSG scale.Results Multivariate conditional logistic regression analysis showed that overworking,children′s fu-ture,depress,anxiety,and like to suppress their emotions could increase the risk of thyroid carcinoma,pleasing e-motion and forget unhappy as soon as possible might prevent the thyroid carcinoma.Conclusion Psychosocial risk factors are important in the onset and progression of the thyroid carcinoma.
