Objective To observe the aging,apoptosis,cell cycle arrest and oxidative stress in human skin fibroblast(HSF)induced by UVB,and to detect the expression profiles of p66Shc,a determinant of oxidative stress response and life span,in this process.Methods HSF cells were exposed to UVB at a subcytotoxic dosage twice a day for three days.The cells without exposure served as control.After another 24-hour culture,SA-β-Gal staining was performed to evaluate the senescence state of the cells,flow cytometry to observe cell apoptosis;cell cycle arrest was detected by serum starvation and flow cytometry:ELISA was applied to detect intracellular levels of superoxide dismutase(SOD)and malondialdehvde(MDA),and Western blotting to analyze the expression of p66Shc protein.Results The percentage of cells positive for SA-β-Gal staining increased from 0 to 98.3% after UVB radiation,which strongly suggested an aging state of HSF cells.The percentage of apoptotic cells increased from 0.96% to 37%.and 80.07% of the HSF cells were arrested in G0/G1 phase following the irradiation.Intracellular SOD activity decreased from(52.35±4.97)ng/g to(7.81±0.68)ng/g(P＜0.01).while intracellular MDA was found to increase from(3.52±0.34)ng/g to(33.91±3.20)ng/g(P＜0.05).The p66Shc protein was found to be weakly expressed in HSF in 24 hours following the exposure to UVB,and a stronger expression was noted 48 hours later.Conclusions HSF cells are induced into a state of senescence associated with oxidative stress after UVB irradiation,which may be applied as an in vitro model in aging research.The expression of p66Shc is increased in HSF during this process,and further studies are needed to explore the relation between p66Shc and oxidative stress as well as cellular aging.

ObjectiveTo investigate the effects of maternal thyroid dysfunction during pregnancy caused by iodine deficiency of different degrees on doublecortin ( DCX ) and synaptophysin ( p38 ) expressions in fetal brain.Methods Wistar female rats were randomly divided into four groups:adequate iodine ( AI),mild iodine deficiency ( MiID ),moderate iodine deficiency ( MoID ),and severe iodine deficiency ( SID ),according to the total daily iodine supply( fed on an iodine deficient diet with different dosages of KI added in drinking water).Three months later the rats were mated.Serum TSH and thyroid hormones were determined in maternal rats on gestational day 20 using chemiluminescent immunoassay.The iodine contents in urine and histological changes of thyroid gland were observed in pregnant rats.The mRNA and protein levels of DCX and synaptophysin ( p38 ) were analyzed in fetal brain by using real time quantitative RT-PCR and western blotting respectively.Results( 1 ) Iodine contents in urine of pregnant rats were reduced with the decrease of their iodine supply.Compared with group AI,serum TSH was significantly increased [ ( 2.95 ± 1.70 vs 1.31 ± 0.55 ) mU/L,P ＜ 0.05 ],and both TT4 and FT4 were significantly decreased [ ( 14.3±4.1 vs 28.4±19.3 ) nmol/L,P＜0.05 ] and [ ( 10.8±3.6 vs 20.2±8.0) pmol/L,P＜0.01 ] in pregnant rats of SID group.Whereas,a slight rise in TSH,and a mild decline in both TT4and FT4 were found in MoID and MiID groups.However,there were no significant changes in TT3 and FT3 levels among these four groups.( 2 )Histological characteristics of thyroid gland in pregnant rats showed a typical goiter with small follicular hyperplasia and lack of colloid in SID group,moderate follicular hyperplasia with decreased colloid in MoID group; but mild cellular hyperplasia without decrease in follicular size and colloid in MiID group.( 3 ) The mRNA levels of DCX were increased in fetal brains of three iodine deficiency groups compared with AI group,but a statistical significance was found in MoID group.The protein levels of DCX in all experiment groups were significantly increased.Both mRNA and protein expressions of synaptophysin ( p38 )were significantly down-regulated in three iodine deficiency groups.Conclusions Maternal thyroid dysfunction caused by iodine deficiency,even by mild or moderate iodine deficiency,may lead to retardation of fetal neuronal and synaptic growth.

Objective To investigate the binding protein of chlamydiaphage phiCPG1 capsid protein Vp1 on chlamydia trachomatis outer membrane.Methods The bacterium with recombinant plasmid Vp1/pet30a( + ) was induced.The expressed protein was purified by gel recycling.FarWestern blot was utilized to' investigate the binding protein of Vp1 on chlamydial outer membrane,including recombinant polymorphic outer membrane protein (rPmp) and major outer membrane protein (MOMP).Results The recombinant protein Vp1 was successfully expressed in E.coli.Monoclonal antibody against Vp1 was used as primary antibody in Western blot,and no specific band was present,which indicated that the monoclonal antibody did not specifically bind with any rPmp.Far-Western blot results showed that there was an obvious band for the rPmpI,but no specific band for other rPmp and MOMP,which suggested that Vp1 could specifically bind with rPmpI protein on the chlamydial outer membrane of serotype D.Conclusions There is a binding site of Vp1 on the chlamydia trachomatis outer membrane.Vp1 may play an important role in the interaction between the chlamydiaphage and the chlamydiae.

ObjectiveTo investigate the association of the expression of the NK cell-activating receptor NKG2D, its ligand major histocompatibility complex class I chain-related gene A (MICA), and related cytokines ［interferon-γ (IFN-γ), interleukin-10 (IL-10), and interleukin-15 (IL-15)］ with intrahepatic inflammation in primary biliary cholangitis (PBC). MethodsLiver biopsy specimens were collected from 30 patients with PBC (PBC group), 15 patients with chronic hepatitis B (CHB group), and 10 patients with nonalcoholic fatty liver disease (NAFLD group), who were hospitalized in The Second Affiliated Hospital of Kunming Medical University from August 2014 to June 2015. The degree of liver inflammation (G) and fibrosis degree (S) of the liver specimens were determined, and immunohistochemistry was used to measure the expression of NKG2D, MICA, IFN-γ, IL-10, and IL-15 in liver tissue (the scores were determined based on the number of cells stained and the degree of staining to evaluate the expression of each marker). A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the t-test was used for comparison between two groups; a Spearman correlation analysis was used to investigate correlation. ResultsIn the PBC group, the expression of NKG2D increased with the degree of inflammation, and the patients with G3-4 inflammation had significantly higher expression than those with G1-2 inflammation (G1 vs G2 vs G3 vs G4: 1.4±0.05 vs 1.56±0.05 vs 1.86±0.11 vs 2.60±0.17, F=150.8, P＜0.05); the expression of NKG2D decreased with fibrosis degree (S3 vs S4: 2.30±0.17 vs 1.56±0.05, t=-1.52, P＜0.05). In the PBC group, there was no significant difference in MICA between G3 and G4 (0.11±0.01 vs 0.20±0.03, t=-2.20, P＞0.05) and between S3 and S4 (0.12±0.02 vs 0.18±0.03, t=-2.64, P＞0.05). In the PBC group, there was a significant difference in the expression of IL-15 between the patients with different degrees of inflammation (G1 vs G2 vs G3 vs G4: 0.70±0.10 vs 1.50±0.10 vs 1.93±0.11 vs 2.60±0.17, F=251.3, P＜0.05), while there was no significant difference between the patients with different fibrosis degrees (S3 vs S4: 2.00±0.05 vs 2.40±0.30, t=-1.62, P＞0.05). In the CHB group, there was a significant difference in the expression of IL-15 between the patients with different degrees of inflammation (G1 vs G2 vs G3: 0.73±0.15 vs 1.96±0.15 vs 2.50±0.17, F=150, P＜0.05) and between the patients with different fibrosis degrees (S1 vs S2 vs S3: 0.70±0.10 vs 21.96±0.15 vs 2.50±0.17, F=158.7, P＜0.05). In the PBC group, the expression of IL-10 was only observed in the patients with G1 inflammation (0.16±0.01), and in the CHB group, the expression of IL-10 was observed in the patients with G1 and G2 inflammation, with no significant difference (G1 vs G2: 0.19±0.01 vs 0.13±0.01, t=-1.522, P＞0.05). In the patients with PBC, the expression of IL-15 in liver tissue was positively correlated with the levels of alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase (GGT) (r=0.241 and 0.407, P=0.014 and 0.045). ConclusionThe NK cell-activating receptor NKG2D affects the degree of intrahepatic inflammation in PBC, and the NKG2D ligand MICA is expressed in the advanced stage of PBC and can downregulate NKG2D. The expression of IL-15 increases with the degree of inflammation in PBC and is positively correlated with the levels of ALP and GGT, suggesting that the activation of NK cells and abnormal secretion of cytokines are involved in the development and progression of PBC and IL-15 may be used as an auxiliary index for the diagnosis of PBC.

Objective:To investigate the value of a 5-point predictive score based on unenhanced CT combined with blood glucose detection for predicting short-term prognosis in patients with spontaneous cerebral hemorrhage.Methods:A total of 102 patients with spontaneous intracerebral hemorrhage who received treatment in Zhejiang Provincial People's Hospital from March 2020 to March 2022 were included in this study and analyzed retrospectively. Blood glucose level was measured and BAT score was used to evaluate hematoma enlargement. After 30 days, Glasgow Outcome Scale was used to evaluate the prognosis of patients. The relationships between blood glucose and BAT score, and between blood glucose and BAT score and prognosis were analyzed. The value of blood glucose and BAT score for predicting short-term prognosis was analyzed.Results:The Glasgow Outcome Scale results showed that among the 102 patients, 24 patients (23.53%) had poor prognosis. The BAT score and blood glucose level in patients with poor prognosis were (3.13 ± 0.68) points and (11.58 ± 2.30) mmol/L, respectively, which were significantly higher than (2.40 ± 0.59) points and (8.88 ± 1.71) mmol/L in patients with good prognosis ( t = 5.10, 5.30, both P < 0.05). Pearson correlation analysis showed that in patients with spontaneous intracerebral hemorrhage, blood glucose level was positively correlated with BAT score ( r = 0.43, P < 0.05). Spearman correlation analysis showed that in patients with spontaneous intracerebral hemorrhage, blood glucose level and BAT level were positively correlated with prognosis ( r = 0.42, 0.47, both P < 0.05). The receiver operating characteristic curve showed that the area under the curve plotted for BAT score combined with blood glucose level for predicting short-term prognosis was 0.874, which was significantly greater than the area under the curve plotted for BAT score alone for predicting short-term prognosis ( Z = 2.54, P < 0.05). Conclusion:A large proportion of patients with spontaneous intracerebral hemorrhage have a poor prognosis. The patients with a poor prognosis have higher blood glucose levels and BAT scores than those with good prognosis. Blood glucose and BAT score have a high value for predicting the prognosis of patients with spontaneous intracerebral hemorrhage.

Objective To evaluate the immunogenicity and safety of inactivated poliovirus vaccine derived from Sabin strain (sIPV) in Banna mini pigs, and to provide experimental evidence for the new animal model. Methods sIPV vaccines which are listed at Institute of Medical Biology at Chinese Academy of Medical Sciences were used in this study. The groups of intramuscular sIPV and the wild strain IPV injections (IPV derived from wild strain, wIPV) were designed, and the saline group was used as a negative control group. The Banna mini pigs in various groups were immunized at 0, 1 and 2 months. Blood samples were collected before immunization and on days 30 after each immunization. Levels of neutralizing antibodies were tested for evaluating immunogenicity. The safety was evaluated by observation of the status and weight of mini pigs. Results After the three dose immunization schedules in the Banna mini pigs, the seroconversion rates of type Ⅰ,Ⅱ and Ⅲ sIPV experimental groups and wIPV group were all up to 100%. The neutralizing antibody levels in all the three types were much higher than the protective titer 1: 8. The weight of mini pigs increased after vaccination. Conclusions The sIPV vaccine has good immunogenicity and safety in Banna mini pigs. Banna mini pigs could be a new animal model for evaluation of sIPV vaccine.
