Objective: To explore the clinical efficacy of thymalfasin on the immune function and inflammatory response in the treatment of patients with severe pneumonia. Methods: From June 2015 to June 2018, 86 patients with severe pneumonia in the Hospital of Zhejiang Provincial General Team of Armed Police were enrolled in the study.According to different treatment methods, they were divided into control group and treatment group, with 43 cases in each group.The control group was treated with cefoperazone/sulbactam sodium on the basis of conventional treatment.The treatment group was treated with thymalfasin on the basis of the treatment of the control group.The expression of monocyte human leukocyte antigen-DR (mHLA-DR), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) levels were measured before and after treatment.At the same time, CD₄⁺, CD₈⁺, CD₄⁺/CD₈⁺ before and after treatment were examined in the two groups.The efficacy and bacterial clearance rate of the two groups were evaluated.The adverse reactions were recorded. Results: After treatment, the levels of IL-6 and TNF-α in the two groups were significantly lower than those before treatment [treatment group: (44.9±11.8)ng/L, (42.9±13.1)ng/L vs. (86.5±27.9)ng/L, (79.6±28.6)ng/L, control group: (71.5±14.2)ng/L, (65.9±22.6)ng/L vs. (87.1±28.6)ng/L, (78.8±29.1)ng/L, t=9.005, 7.650, 3.203, 2.295, all P<0.05]. The expression level of mHLA-DR in the treatment group after treatment [(44.8±5.7)%] was significantly higher than that before treatment [(27.1±3.4)%, t=17.487, P=0.000]. The changes of the indicators in the treatment group were significantly better than those in the control group (t=9.447, 5.773, 8.725, all P<0.05). After treatment, the CD₄⁺ level of the two groups were higher than those before treatment, and the CD₈⁺ levels of the two groups were significantly lower than those before treatment, the differences were statistically significant(t=3.050, 3.429, 6.965, 13.327, all P<0.05), and the CD₄⁺/CD₈⁺ of the two groups were significantly increased (t=0.370, 3.314, all P<0.05). The indicators of the treatment group were improved more significantly than the control group (t=4.416, 12.355, 3.089, all P<0.05). The bacterial clearance rate of the treatment group was 88.89% (32/36), which was significantly higher than that of the control group [67.65% (23/34), χ²=4.686, P=0.030]. The clinical efficacy of the treatment group was 93.02%(40/43), which was significantly higher than 76.74%(33/43) of the control group (χ²=6.095, P=0.047). The incidence of adverse reactions between the two groups had no statistically significant difference (χ²=0.212, P=0.645). Conclusion Thymalfasin in the treatment of patients with severe pneumonia can improve the immune function, reduce the inflammatory response, improve the bacterial clearance rate and clinical efficacy, and will not increase the adverse reactions, so it is worthy of promoting.

Biotinylated chitosan nanoparticles (Bio-CS-NP) were prepared for the active delivery to cancer cells and its characterization was investigated in this study. The preparation process included two steps. First, biotinylated chitosan ( Bio-CS ) was obtained through a reaction between sulfosuccinimidobiotin and chitosan (CS). Second, Bio-CS-NP were prepared by the precipitation of Bio-CS with sodium chloride solution. With a biotin reagent box, the conjugation densities of biotin on the surface of Bio-CS-NP were determined. The morphology and diameter of the nanoparticles were assayed by transmission electron microscope (TEM) and laser light scattering particle analyzer, respectively. The uptake of nanoparticles by human hepotacarcinoma HepG2 cells, for example, Bio-CS-NP and chitosan nanoparticles (CS-NP) without any modification, was quantitatively examined. The results indicated that the conjugation densities of biotin on the surface of Bio-CS-NP were 2.2 biotin CS. Bio-CS-NP were spherical, smooth on the surface. The average diameter was 296.8 nm. The polydispersion index was 0.155. The uptake of Bio-CS-NP by HepG2 cells was much higher than that of CS-NP (P < 0.05). It demonstrated that Bio-CS-NP can be applied as a new vehicle to actively deliver anticancer drugs to tumor cells. The method for the determination of biotin was simple and practical.

BACKGROUNDIntravenous urography (IVU) combined with add-on CT (IVU-CT) can help to provide more diagnostic information for determining the localization and nature of ureteral abnormalities with less irradiation dose. This study aimed to determine the value of IVU-CT for diagnosis of ureteral diseases, where IVU is insufficient to determine the diagnosis.

METHODSTwo hundred and eighty patients underwent IVU for suspected ureteral disorders, which identified a definite diagnosis in 184 cases and was insufficient for definite diagnosis in 96 cases designated as indeterminate diagnosis. Subsequently 90 patients (six patients declined CT) with indeterminate diagnosis consented to undergo immediate or delayed helical CT scan. The CT data were transferred to the workstation for post-processing, and the cost and mean effective dose for each imaging method were calculated and compared indirectly.

RESULTSOf the 90 indeterminate diagnosis cases, diagnosis was determined in 86 cases by IVU-CT with a diagnostic accordance rate of 95.6%, while 184/280 (65.7%) had diagnosis determined by IVU alone. There was a significant difference between IVU and IVU-CT in the determination of the diagnosis of ureteral diseases (c(2) = 36.4, P < 0.05). The cost of IVU equals to 1/8 - 1/9 of that for CT urography (CTU), and the cost of IVU-CT is as much as 1/3 of CTU. CTU results in the highest mean effective dose, approximately nine times that for IVU and three times that for IVU-CT.

CONCLUSIONIVU-CT provides valuable information for the localization and diagnosis of ureteral abnormalities and may be considered as an efficient, cost-effective and low-dose diagnostic technique in this setting.

OBJECTIVETo clone the recombinant human islet neogenesis-associated protein (rhINGAP) gene for its secretory expression in Pichia pastoris.

METHODSINGAP gene was amplified with PCR and inserted between Xho I and EcoR I downstream sites of the alpha factor of the recombinant plasmid alpha/pUC18. The fusion gene of alpha factor and INGAP was subsequently inserted between BamH I and EcoR I sites of the plasmid pPIC9K of P. pastoris. After confirmation with restriction enzyme digestion and sequencing, the positive recombinant plasmid that integrated INGAP gene was linearized with Sal I digestion and transformed into the yeast host strain GS115 through electroporation. The yeast transformants that harbored the INGAP gene with high copies were selected with the auxotroph medium and G418, followed then by PCR verification of the positive transformants, from which the expression of recombinant human INGAP was induced with methanol as the only carbone source. The antigenic activity of the desired protein was then detected using Western blotting and enzyme-linked immunosorbent assay (ELISA).

RESULTS AND CONCLUSIONThe recombinant expression plasmid INGAP/pPIC9K was successfully constructed, and 3 positive transformants were obtained. The expressed protein showed good antigenic activity as confirmed by Western blotting and ELISA.
