Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective To investigate the characteristics of traditional Chinese medicine(TCM)syndrome elements and the distribution patterns of TCM syndromes in senile osteoporosis(SOP),providing a reference for TCM treatment of SOP.Methods A cross-sectional study was conducted on 200 SOP patients aged over 70 years treated at Wuxi Huishan Chinese Medicine Hospital from January 2022 to June 2023.General information and TCM diagnostic data were collected.The syndrome element differentiation scoring method was employed for analysis.Results(1)Among the 200 SOP patients,the most prevalent disease-location syndrome element was kidney(61.50％),followed by liver(48.50％),bones and tendons(45.50％),spleen(37.00％),meridians(25.50％),heart(12.50％),and lung(10.50％).Statistical analysis showed significantly higher syndrome element scores for kidney,liver,bones and tendons,spleen,and meridians compared to heart and lung(P＜0.01).(2)Regarding disease-nature syndrome elements,deficiency-type elements predominated,with yang deficiency(52.50％)being most common,followed by blood deficiency(46.00％),essence depletion(45.50％),qi deficiency(45.50％),yin deficiency(37.00％),unconsolidation(25.50％),and qi sinking(15.50％).Yang deficiency,blood deficiency,essence depletion,qi deficiency,and yin deficiency scores were significantly higher than those of insecurity and qi sinking,the difference being statistically significant(P＜0.01).Among excess-type elements,cold(47.00％)was most prevalent,followed by blood stasis(45.00％),qi stagnation(43.50％),dampness(34.50％),phlegm(27.50％),and heat(25.00％).Cold and blood stasis scores were significantly higher than phlegm,while cold,blood stasis,qi stagnation,dampness,and phlegm scores were significantly higher than heat,the difference being statistically significant(P＜0.05).(3)Eighteen TCM syndrome patterns were identified.Spleen-kidney yang deficiency(40.00％)was most frequent,followed by liver blood deficiency(37.50％),kidney essence insufficiency(35.00％),qi stagnation and blood stasis(31.00％),cold congelation and obstruction(25.50％),phlegm-damp obstruction(27.50％),and qi-yin deficiency with qi insecurity(11.00％).Based on syndrome element scores,the primary syndromes were defiined as spleen-kidney yang deficiency(35.60％),liver blood deficiency(25.13％),kidney essence insufficiency(18.32％),and qi stagnation and blood stasis(13.09％),etc.Conclusion The characteristic TCM syndrome elements of SOP patients involve qi-blood-yin-yang deficiency of kidney,spleen,and liver,combined with cold congelation,blood stasis,and qi stagnation.The main TCM syndromes are spleen-kidney yang deficiency,liver blood deficiency,kidney essence insufficiency,and qi stagnation with blood stasis.

Objective To study the changes of cytokines in aqueous humor of patients with proliferative diabetic retinopathy (PDR)after intravitreal bevacizumab (IVB) and the correlation of these cytokines.Methods Fifty-six patients(63 eyes) with severe PDR underwent pars piana vitrectomy (PPV) with IVB pretreatment in our hospital from April,2014 to February,2015 were collected.All the patients received IVB therapy from 3 days to 7 days before PPV.Aqueous humor samples were collected at the time of IVB and PPV treatment.The concentrations of vascular endothelial growth factor (VEGF),interleukin-6 (IL-6),interleukin-8 (IL-8) and monocyte chemotactic protein-1 (MCP-1) were measured by cytoinetric bead array (CBA).The changes of these cyto-kines after IVB were analyzed by using Wilcoxon rank sum test for paired data.The correlation between these cytokines was analyzed by using Spearman rank test.Results From 3 days to 7 days after IVB,the concentration of VEGF in aqueous humor was (6.57 ± 12.29)pg · mL-1,lower than the pre-operation of (278.71 ±340.20)pg · mL-1,the difference was statistically significant (P ＜ 0.05).The concentration of IL-8 was (385.60 ± 1099.47) pg · mL-1,higher than pre-operation of(298.87 ± 1005.79) pg ·mL-1,the difference was statistically significant (P ＜ 0.05).IL-6 and MCP-1 were increased after IVB,but the difference was not statistically significant (all P ＞ 0.05).VEGF,IL-6,IL-8 and MCP-1 had an obviously relationship between each two factors(all P ＜ 0.05).Conclusion Angiogenesis in patients with PDR are regulated by a variety of cytokines,and targeted reduction of VEGF may compensatory increase the concentration of other inflammatory cytokines.

Objective To investigate the incremental value of 99Tcm-MIBI SPECT/CT imaging in the preoperative diagnosis of PHPT.Methods Forty-one patients (13 males,28 females,age range:14-82 (50.0± 13.2) years)with PHPT were retrospectively enrolled.99Tcm-MIBI dual-phase planar scan,SPECT/CT imaging,CT and neck ultrasound were performed before surgery.All patients had pathological results.McNemarx2 test was used to compare the detection rates of the four imaging methods.ROI method was applied to calculate the uptake ratio (T/NT) and Pearson correlation analysis was used to evaluate correlation between T/NT and serum intact PTH,Ca,the lesion volume measured after parathyroidectomy.Results A total of 42 parathyroid lesions were confirmed by pathology.There were 39 patients with parathyroid adenoma (2 with double adenomas,and 37 with single adenoma containing 2 ectopic adenomas) and 1 patient with parathyroid carcinoma.The detection rate of planar scan,SPECT/CT imaging,CT and neck ultrasound were 78.0％ (32/41),92.7％ (38/41),73.2％ (30/41) and 70.7％ (29/41) respectively.Detection rate of SPECT/CT imaging was significantly higher than that of planar scan,CT or ultrasonography (x2 =4.17,4.90,5.82,all P＜0.01).However there were no remarkable differences between the detection rate of planar scan and that of CT or ultrasonography (x2=0.08,0.36,both P＞0.05).Detection rates of CT and ultrasonography were not significantly different either (x2 =1.90,P＞0.05).T/NT in delayed planar imaging were significantly correlated with PTH,Ca and the lesion volume measured after parathyroidectomy (r =0.56,0.54,0.56,all P＜0.01).Conclusions Compared with 99Tcm-MIBI dual-phase planar scan,CT and ultrasonography,SPECT/CT imaging could be of important clinical value for preoperative localization of PHPT because of its higher detection rate and accurate anatomical localization ability.

Objective To construct the eukaryotic expression vector harboring the fragment of Alia gene, and to investigate the effects of it on the signal of quorum sensing and virulence factors producted by Pseudomonas aeruginosa(Pa). Methods The plasmid pET-AiiA was cutted by Nhe Ⅰ and Xho Ⅰ , then the AiiA fragment was cloned into eukaryotic expression vector pEGFP-N2. After the plasmid was transfected into A549 cells, the protein was extracted and AiiA protein was found in it by Western blot. After the extrac- tion was admixed into the LB broth, from culture supernatant extracts of Pa, the N-acylhomoserine lactone (AHL) was detected by bioassay, and the expression of pyocyanin and elastase were assayed by RT-PCR and optical density. Results The fragment of AiiA gene was cutted and then cloned into pEGFP-N2. AiiA protein was found in the transfected cells. After admixed with the extract harboring AiiA protein, in Pa medium, the AHL was hydrolyzed, and the expression of pyocyanin and elastase were reduced. Conclusion The virulence factors synthesized by Pa were reduced by the AiiA protein expressed in eukaryotic cell.
