Objective To detect the signal pathways through which IL-4 regulates expression of DC-SIGN in THP-1 cells.Methods We used phorbol 12-myristate 13-acetate(PMA) differentiated THP-1 cells as the in vitro model of monocyte/macrophage cells to study the signal pathways involved in IL-4 regulated expression of DC-SIGN.DC-SIGN mRNA expression was detected by RT-PCR.Cytoplasmic DC-SIGN protein was tested by Western blot.Flow cytometry was used to detect cell surface expression of DC-SIGN.Cytoplasm and nuclear protein of PMA stimulated THP-1 cells induced by IL-4 for 0,10,20,30,60 and 120 min was extracted and detected by Western blot for signal pathway signaling protein and phosphoprotein.Results We found that a high expression of DC-SIGN could be induced by IL-4 at the levels of mRNA and cell surface protein.Up-regulated expression of DC-SIGN was almost completely blocked by the specific inhibitor of ERK pathway,and partly reduced by the specific inhibitors of JAK-STAT and NF-κB pathways.The activation of the three signaling pathways was directly confirmed by testing the phosphorylation of protein kinase within the cytoplasm and nucleus over time.Conclusion Multiple signaling pathways are involved in IL-4 induced high expression of DC-SIGN on THP-1 cells,in which ERK pathway is the main signal pathway.

Objective A recombinant adenoviral vector containing mIL-18BP and mIL-4 fusion gene(AdmIL-18BP/mIL-4) was constructed and used to investigate the role of mIL-18BP and mIL-4 in medula-ring the expressions of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthetase (iNOS) and their inducing products PGE2, NO in murine collagen-induced arthritis. Methods Male DBA-1/BOM mice were used in this study. Mice with CIA were intra-articularly injected with 107 pfu/6μl of AdmIL-18BP/mIL-4.Intra-articular injections of AdLacZ or PBS were used as controls. The mRNA expression of COX-2, iNOS in synovial tissue was analyzed by semi-quantitative RT-PCR. Expression of COX-2 and iNOS protein was estimated by Western blot method. The production of PGE2 and NO in synovia was detected by competitive ELISA and enzyme reduction of nitrate. Results The expression of COX-2, iNOS mRNA in routine synovial tissue of AdmIL-18BP/mIL-4 treatment group was significantly lower than that of AdLacZ group (0.15 vs 0.42,P<0.01 ; 0.05 vs 0.77, P<0.01) and PBS group (0.15 vs 0.65, P<0.01; 0.05 vs 0.64, P<0.01 ). And the protein expression of COX-2, iNOS from AdmIL-18BP/mIL-4 treatment group was also obviously lower than that of AdLacZ group (0.08 vs 0.92, P<0.01; 0.11 vs 1.00, P<0.01) and PBS group (0.08 vs 0.77, P<0.01; 0.11 vs 0.84, P<0.01 ). The PGE2 and NO production in synovia of AdmIL-18BP/mIL-4 treatment group was significantly lower than that of AdLacZ group [(0.68x0.06) vs (2.58±0.21)ng/mL, P<0.01; (23.4+2.5) vs (60.0±11.3)μmol/L, P<0.01 ] and PBS group [(0.68±0.06) vs (2.57±0.20)ng/mL, P<0.01; (23.4+2.5) vs (60.3±13.4)μmol/L, P<0.01]. Conclusion These data indicat that local over-expre-ssion of mIL-18BP and mIL-4 can down-regulate COX-2, iNOS and their induced product PGE2, NO in CIA mice. The combination treatment with mIL-18BP and mIL-4 is a promising therapeutic target for RA.

Objective: To investigate the efficacy and safety of scolosis-specific exercises (SSE) in reducing adolescent idiopathic scoliosis (AIS) progression, and to provide a reference for developing and promoting AIS non-surgical treatment methods and public health decisions. Methods: By using "scoliosis" "spine" "scoliosis-specific exercises" "spinal deformities" "idiopathic" "adolescent" "etiology" "treatment" "exercise" as Chinese and English search terms, literature search was conducted in PubMed, Embase, Sport, Discus, Central, Web of Science and CNKI databases from December, 2019. The RevMan 5.3 software was used for Meta-analysis. Results: Compared with the control group, SSE shows positive effects on improving scoliosis, including reduction of Cobb Angle in cervical vertebra (n=245, MD=-6.88, 95%CI=-7.70--6.05,P<0.01), reduction of Cobb Angle in lumbar vertebra (n=135, MD= -6.85, 95%CI=-10.06--3.63, P<0.01), improvement of physiological curve of spine (n=217, MD=-4.13, 95%CI=-7.92--0.35, P<0.01); In terms of improving quality of life, compared with the control group, patients in the SSE group were better able to improve the function of SRS-22 (n=276, SMD= 2.00, 95%CI=1.69-2.30, P<0.01) and self-image of SRS-22 (n=250, SMD=0.86, 95%CI=0.58-1.14, P<0.01) and reduce the pain value of SRS-22 (n=206, SMD=0.81, 95%CI=0.51-1.10, P<0.01). Conclusion SSE treatment can better improve the function of AIS patients and obtain better orthopedic effects than other types of sports or standard nursing methods. In the future, more high-quality researches are needed to further evaluate the efficacy and safety of SSE treatment and other types of sports or standard care methods for AIS.

ObjectiveTo explore the effect of swimming on motor behavior and expression of brain derived neurotrophic factor(BDNF) and trkB in adrenal body.MethodsSD adult rats were divided into normal cotrol group and swimming group ( n=10 in each group).All rats in swimming group were subjected 6 weeks swimming for 1h each day.Motor performances including swimming speed and distance were recorded and expression of BDNF and trkB in adrenal body was measured.ResultsThere was a significant increase in swimming speed ( ( 157 ± 60) m/min) and distance ( (283.36 ±49.50)m) in swimming group,compared with control group ( (283± 60) m/min,( 156.92 ± 29) m) (P ＜ 0.05 ).Simultaneously,expression of BDNF in adrenal body had been significantly unregulated (0.93 ± 0.09 vs 0.56 ± 0.19 ) (P ＜ 0.05 ),while expression of trkB kept to be not changed.ConclusionSwimming increases notor ability in rats,and the possible mechanism may be related the upregulation of BDNF in adrenal body.

Objective To observe the effects of different modes treadmill training on cognitive func-tion and transforming growth factor β1 ( TGF-β1 ) expression in cerebral cortex of rats. Methods Two months old rats were divided into the control group,piecewise training group and intermittent training group ( n=10 in each group) . The training was performed five times a week for 6 weeks. Learning and memory a-bility of all rats was detected by water maze at 6 weeks after the training. TGF-β1 expression and localization in cerebral cortex was tested by QRT-PCR and immunofluorescence, respectively. Results The platform time in piecewise group ((30±28) s) and intermittent group ((25±23)s) was both significantly shorter than that in control group ((58±50)s). In the space exploration,the time around Ⅳ quadrant platform in piecewise group((23.6±3.9)s) and intermittent group ((24.3±8.9)s) was significantly higher than that in the control group((17.7±2.0)s). The expression of TGF-β1 mRNA in cerebral cortex in intermittent group (0.0067±0.0043)was obviously higher than that in piecewise group (0.0035±0.0006) and control group (0.0041±0.001). TGF-β1 was located in cell membrane and cytoplasm,and the relative optical density of intermittent group (0.0045±0.0017) was significantly higher than that of control group (0.0019±0.0004) and staging group (0.00175±0.00045). Conclusion (1)Learning and memory function both were im-proved after treadmill six weeks with piecewise and intermittent training models. ( 2) The level of TGF-β1 gene and protein was significantly increased after interval training in cortex of rats.

Objective: To evaluate diet quality and related problems among children and adolescents in Yunnan Province, in order to provide a theoretical basis for the formulation of targeted dietary interventions for children and adolescents in this region. Methods: Using a stratified random sampling method, 1 078 primary and secondary school students from six prefecture level cities in Yunnan Province were selected from August to November 2022. Dietary quality was evaluated by applying the China Children s Dietary Index (CCDI-2016) on the basis of a 3 d 24 h dietary survey. Results: The total dietary index score of children and adolescents in Yunnan Province was 62.63(54.57,71.19). The overall recommended intakes were largely achieved by consumption of cereals, eggs and sugary drinks, with dietary index scores of 9.91(8.24,10.00), 5.58(0,8.58) and 9.20(7.38,10.00), respectively; there were inadequate intakes of vegetables, legumes, water, vitamin A and dietary fiber, with scores of 5.63(4.09,7.59), 3.48 (0,9.70), 4.23(2.67,5.50), 2.33(1.56,3.53), 3.19(1.63,5.67), respectively; intake of fruits, dairy and aquatic products were severely deficient, with scores of 0(0,1.74), 0(0,2.37), 0(0,9.85), respectively; excessive intake of meat was found, with a dietary index score of 0(0,2.46). The stratified analysis showed that children and adolescents aged 11-13 years had the highest total dietary scores[65.35(54.29,72.03)], followed by those aged 7-10 years[63.46(56.19,72.63)], while the 14-17 year old age group had the lowest scores[59.07(51.15,68.30), H=32.23, P <0.01]. Girls had higher total dietary scores than that of boys[64.20(56.12,72.56), 59.32(52.60,69.72), Z=-5.16, P <0.01], while urban children and adolescents had higher total dietary scores than rural children and adolescents[65.30(54.84,73.62), 62.17(54.31,70.70), Z=-2.11, P <0.05]. Furthermore, higher total dietary index scores were observed among children and adolescents whose parents had a higher educational level( H=27.68, 22.58, P <0.01). The comparison of ethnic groups revealed that the Wa children and adolescents had the highest total dietary index scores, while the Hani children had the lowest( H=27.51, P <0.01). Conclusion The overall dietary quality of children and adolescents in Yunnan Province is not high, the imbalance of dietary nutrition is prominent, and the dietary structure needs to be adjusted and optimized. Intervention programs should focus on the problem of insufficient intake of fruits and vegetables, milk and legumes, aquatic products and excessive intake of poultry meat among children and adolescents.

Objective:To analyze the clinical characteristics of monkeypox patients.Methods:The clinical data and laboratory findings of 4 patients with monkeypox patients diagnosed at Yiwu Central Hospital in July 2023 were analyzed. Herpes fluid and skin tissue samples were collected, the viruses were isolation and cultured in African green monkey kidney cells (Vero) and identified with whole gene sequencing.Results:All four patients were male, aged 24-35 years. All patients had male-to-male behavior within 21 days before onset of the disease. Among them, one patient has AIDS and one patient has syphilis. Four patients presented with perineal skin lesions with itching, and 3 patients were found to have enlarged lymph nodes upon admission. Laboratory testing: lymphocyte abnormality (4.57×10 9/L) in 1 case; increased procalcitonin (0.25 ng/mL) in 1 case; elevated IL-10 levels ( 7.11 ng/L and 9.42 ng/L) in 2 cases; increased IL-6 (66 ng/L) and IL-4 (3.24 ng/L) in 1 case, respectively. One case had abnormal myocardial zymogram with a elevated lactate dehydrogenase level of 313 U/L. The monkeypox virus was isolated from lesion tissue and herpes fluid, and the whole gene sequencing identified it as the B. 1.3 subtype of the IIb evolutionary branch, exhibiting typical pathological effects on Vero cells. Conclusion:The clinical manifestations of the 4 monkeypox patients confirmed in Zhejiang province are mild, patients had a definitive history of male-to-male sexual behavior and the virus strains belong to the B. 1.3 lineage of the IIb evolutionary branch.
