OBJECTIVE: To evaluate the effectiveness of double joystick technique assisted closed reduction and Kirschner wire internal fixation in the treatment of Gartland type Ⅲ supracondylar fractures of the humerus (SCFH) in children. METHODS: A retrospective study was conducted on 28 cases of Gartland type Ⅲ SCFH with complete data available, who underwent closed reduction and Kirschner wire internal fixation with the double joystick technique between August 2022 and July 2024. There were 23 boys and 5 girls, with an average age of 6.4 years (range, 1-12 years). All fractures resulted from falls and were classified as extension-type. X-ray film showed the radial displacement of the distal fragment in 15 cases and unlar displacement in 13 cases. The interval from injury to operation was 3-36 hours (mean, 19.5 hours). X-ray film re-examination was conducted to evaluate the fracture healing, and the Baumann angle of affected elbow joint and carrying angle of bilateral elbow joints were measured. Elbow joint function was evaluated using the range of motion (flexion and extension) and the Flynn criteria. The above indicators were compared between affected and healthy sides. RESULTS: All operation were successfully completed. The operation time ranged from 15 to 40 minutes (mean, 25.2 minutes). The length of hospital stay was 2-5 days (mean, 3.5 days). All patients were followed up 3-24 months (mean, 11.8 months). X-ray film confirmed fracture healing in all patients, with a mean healing time of 5.4 weeks (range, 4-6 weeks). At last follow-up, the Baumann angle of the affected elbow joint was (73.50±3.46)°, and the carrying angle and the range of motion in flexion and extension of the affected elbow joint were significantly less than the contralateral side (P<0.05). According to the Flynn criteria, the elbow joint function of the affected elbow was evaluated as excellent in 25 cases and good in 3 cases, with an excellent and good rate of 100%. CONCLUSION The double joystick technique is a safe and effective method which can facilitate the closed reduction and Kirschner wire internal fixation of Gartland type Ⅲ SCFH in children without increasing risk of complications.

OBJECTIVE: Observational studies have found associations between inflammatory bowel disease (IBD) and the risk of dementia, including Alzheimer's dementia (AD) and vascular dementia (VD); however, these findings are inconsistent. It remains unclear whether these associations are causal. METHODS: We conducted a meta-analysis by systematically searching for observational studies on the association between IBD and dementia. Mendelian randomization (MR) analysis based on summary genome-wide association studies (GWASs) was performed. Genetic correlation and Bayesian co-localization analyses were used to provide robust genetic evidence. RESULTS: Ten observational studies involving 80,565,688 participants were included in this meta-analysis. IBD was significantly associated with dementia (risk ratio [ RR] =1.36, 95% CI = 1.04-1.78; I ² = 84.8%) and VD ( RR = 2.60, 95% CI = 1.18-5.70; only one study), but not with AD ( RR = 2.00, 95% CI = 0.96-4.13; I ² = 99.8%). MR analyses did not supported significant causal associations of IBD with dementia (dementia: odds ratio [ OR] = 1.01, 95% CI = 0.98-1.03; AD: OR = 0.98, 95% CI = 0.95-1.01; VD: OR = 1.02, 95% CI = 0.97-1.07). In addition, genetic correlation and co-localization analyses did not reveal any genetic associations between IBD and dementia. CONCLUSION Our study did not provide genetic evidence for a causal association between IBD and dementia risk. The increased risk of dementia observed in observational studies may be attributed to unobserved confounding factors or detection bias.

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 incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

The concept of'harmony'is the soul of traditional Chinese culture,which has a profound impact on the formation and development of traditional Chinese medicine(TCM).TCM is rooted in traditional Chinese culture,and the mode of thinking in TCM is in line with traditional Chinese culture.Based on the harmony culture,TCM has developed a unique view of health,disease and therapeutics.From the view of the harmony culture and by combining with years of clinical experience in treating dermatosis,Chinese medical master XUAN Guo-Wei has applied the concept of'harmony'in the TCM syndrome differentiation and treatment system in clinic,and has developed the academic thoughts of harmonizing therapy for removing toxins for the diagnosis and treatment of dermatosis.The thoughts of harmonizing therapy for removing toxins includes four aspects,namely harmonizing yin and yang,harmonizing healthy qi and pathogenic qi,harmonizing water and fire(i.e.,clod and hot),and harmonizing the administration of formula and drugs,aiming to remove toxins and expel pathogens and value the harmony.The thoughts of harmonizing therapy for removing toxins will beneficial to the comprehensive understanding of the unique health-disease-therapeutics concept in TCM,and will be helpful for managing the doctor-patient relationship,which is of enlightening significance to the modern clinical practice with TCM.

Objective To investigate the role and action mechanism of rosemarinic acid(RA)on the malignant behavior of colorectal cancer(CRC)SW480 cells.Methods We collected tumor tissues from patients with primary untreated CRC who underwent surgery in People's Hospital of Rugao from January 2019 to December 2020,as well as colon tissues from normal individuals.The expression of β-catenin was detected by immunohistochemistry and Western blotting to analyze its relationship with the clinical stage,prognosis,and immune infiltration.CCK-8 was used to detect the effects of 10,15 and 20 μmol/L of RA on the proliferation of SW480 cells;flow cytometry detected apoptosis;Transwell and scratch assay detected changes in the invasion and migration ability of the cells,respectively.Western blotting detected the expressions of proteins related to apoptosis,epithelial-mesenchymal transition(EMT),and Wnt/β-catenin pathway.A mouse model of CRC transplant tumor was established,and the effect of RA on the growth of transplant tumor was investigated by gavage administration.The levels of inflammatory factors were detected by ELISA.Results The expression of β-catenin was low in normal colon tissues and significantly higher in CRC tissues.In the CRC patients with high expression of β-catenin,the number of patients with tumors larger than 5 cm was significantly higher than that in the low expression group,whereas the overall survival of the patients was significantly smaller than that in the low expression group(P＜0.05).Cell proliferation was significantly inhibited and decreased in a concentration-dependent manner in the RA group at all concentrations(P＜0.05).In animal experiments,the expression of apoptotic proteins Bax and Bad was significantly increased and the expression of anti-apoptotic protein Bcl-2 was significantly decreased in the RA-treated group compared with the control group(P＜0.05).It was also found that the invasive and migratory ability of SW480 cells was significantly inhibited(P＜0.05),the expression of E-cadherin protein was significantly increased,the expression of Snail,N-cadherin and Vimentin was significantly reduced(P＜0.05),the expression of Axin and GSK-3β was increased,and the expression of β-catenin was reduced(P＜0.05).Conclusion RA may inhibit the biological activity of SW480 by interfering with Wnt/β-catenin pathway-mediated EMT.

[Objective] To investigate the inhibitory effect of quercetin on cisplatin-resistant human colorectal cancer (CRC) cells SW480 and SW620 and its possible mechanism. [Methods] Cisplatin-resistant subtypes of SW480 and SW620 cells were first cultured and the effects of quercetin on cell proliferation and chemosensitivity were determined by MTT assay. Flow cytometry was used to detect apoptosis and protein blotting was used to detect the expressions of relevant proteins. [Results] MTT assay showed that quercetin at the concentrations of 80 μmol/L and 160 μmol/L significantly inhibited the proliferation of SW480 and SW620 cells. Flow cytometry results showed that the apoptosis rate was significantly higher in the cisplatin combined with quercetin group than in the other three groups. Protein blotting showed that cleaved-caspase-3 and caspase-9 expressions were significantly increased in the cisplatin combined with quercetin group. The chemotherapeutic drug sensitivity assay showed that the elevated IC50 of drug-resistant cells was decreased significantly after quercetin administration (P<0.05). [Conclusion] The present study clarifies that quercetin can increase the sensitivity of human CRC cells to cisplatin. This effect may be related to its mechanism of action in affecting cell proliferation, apoptosis and autophagy.

Modern Chinese medicine studies have confirmed that the interaction between traditional Chinese medicine(TCM)and intestinal flora is the key to the treatment of diseases with tradi-tional Chinese medicine.This interplay includes such activities as:traditional Chinese medicine can be metabolized by intestinal flora into effective components with different biological activities from its precursors;TCM chemicals improve the composition of gut microbiota,consequently ameliorating its dysfunction as well as associated pathological conditions;and gut microbiota mediate the interactions between the multiple chemicals in TCM.There-fore,it becomes an important way to understand the modern sci-entific connotation of traditional Chinese medicine theory to study the pharmacological mechanism of the efficacy of traditional Chi-nese medicine by targeting Gut microbiota.

AIM: To compare the effectiveness and complications of treating rhegmatogenous retinal detachment(RRD)with foldable capsule body(FCB)and scleral buckling(SB).METHODS: The clinical data of 81 patients(82 eyes)with RRD who underwent surgery at our hospital from March 2019 to April 2022 were retrospectively analyzed. The differences in retinal reattachment rate, best-corrected visual acuity, the absorption of subretinal fluid, postoperative discomfort and incidence of complications between the two treatments were compared.RESULTS: The retinal reattachment rate was 96% in the FCB group and 92% in the SB group, with no significant difference between the two groups(P>0.05). The best corrected visual acuity of the affected macular eyes was different in the both groups(P<0.01). Both groups effectively promoted the absorption of subretinal fluid. The operation time of FCB group was 16.50(12.75, 25.00)min, while it was 38.00(36.25, 41.75)min in the SB group(P<0.001). Patients in the FCB group also had significantly lower eyelid swelling and pain symptoms than those in the SB group(P<0.001). The visual analogue scale(VAS)score at 1d after operation was 1.00(0.00, 2.00)in the FCB group and 3.00(2.00, 3.00)in the SB group(P<0.001).CONCLUSION: FCB is a safe and effective surgical method to treat RRD that can alleviate patient's pain. Furthermore, FCB has a significantly shorter operation time and milder postoperative adverse reactions than SB.
