Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

ObjectiveTo observe the clinical efficacy of modified Jinwei Guben Decoction （金卫固本汤， MJGD） combined with Bailing Capsule （百令胶囊， BC） in the treatment of chronic obstructive pulmonary disease （COPD） patients in the stable stage with qi deficiency， blood stasis and phlegm obstruction syndrome， in addition to conventional western medicine treatment. MethodsA total of 102 patients with stable COPD and qi deficiency， blood stasis， and phlegm obstruction syndrome were included in the study. According to the patients'preferences， they were divided into treatment group （49 cases） and control group （53 cases）. The control group received conventional western medicine treatment， while the treatment group was given MJGD （1 dose daily） combined with BC （2.0 g each time， three times a day） additionally. The treatment period was 3 months， and the patients were followed up for 1 year after the treatment. The acute exacerbation frequency （mild， moderate， severe） before treatment， during treatment， at 6-month follow-up， and at 1-year follow-up was compared between groups. Additionally， the lung function indicators such as FEV₁， FEV₁%pred， FVC， and FEV₁/FVC ratio， traditional Chinese medicine （TCM） syndrome scores， modified British Medical Research Council （mMRC） dyspnea scale， and the COPD Assessment Test （CAT） scores before and after treatment were compared. A logistic regression model was constructed to analyze the impact of MJGD combined with BC on clinical efficacy. ResultsFour patients dropped out from the treatment group and eight from the control group， leaving 45 patients of each group for statistical analysis. The number of mild and moderate acute exacerbations in the treatment group was lower than that in the control group during the treatment period， at 6-month follow-up and within 1 year of follow-up （P＜0.05） .The number of severe acute exacerbations was only lower in the treatment group than in the control group at 6-month follow-up （P＜0.05）. Compared with that before treatment， the number of acute exacerbations of all degrees in the treatment group was significantly reduced within 1 year of follow-up （P＜0.05），while only the number of mild acute exacerbations in the control group was significantly reduced within 1 year of follow-up （P＜0.05）. The treatment group showed significant improvement in FEV₁ and FEV₁%pred and FEV₁/FEV， while the control group showed a significant decline in FEV₁ and FVC （P＜0.05）. After treatment， both groups showed significant reductions in TCM syndrome scores， including coughing， sputum， wheezing， chest tightness， shortness of breath， and fatigue， as well as mMRC and CAT scores （P＜0.05）， with the treatment group having significantly lower scores than the control group （P＜0.05）. The overall clinical effective rate of in the treatment group was 93.33% （42/45）， significantly higher than that of the control group， 75.56% （34/45， P＜0.05）. Multivariate logistic regression analysis showed that the use of MJGD combined with BC （OR = 4.68， 95%CI： 1.15 - 19.09， P = 0.03） was positively correlated with clinical efficacy. ConclusionsIn addition to conventional western medicine treatment， the combination of MJGD and BC can reduce the frequency of acute exacerbations， delay the decline of lung function， improve clinical symptoms， and significantly enhance the clinical efficacy in patients with stable COPD and qi deficiency， blood stasis， and phlegm obstruction syndrome.

Objective: To investigate the prevalence of Dengue virus (DENV) infection among voluntary blood donors in Xishuangbanna Dai Autonomous Prefecture, and to evaluate the necessity of implementing nucleic acid testing (NAT) for blood donors during the rainy season (May-October). Methods: Prior to initiating donor screening, the Xishuangbanna Central Blood Center conducted in-house validation of reagent performance and participated in external quality assessment (EQA) organized by the National Center for Clinical Laboratories (NCCL). During the surveillance period (August-October 2024), a total of 2 919 donor samples were screened using a 6-sample mini-pool NAT strategy. Daily internal quality controls were recorded. Samples that tested positive in pooled screening were deconvoluted and retested in duplicate; only those reactive in both replicate wells were sent to the NCCL for confirmatory testing. At NCCL, samples underwent re-testing using five domestic NAT reagents, as well as serological assays for NS1 antigen and DENV-specific IgG/IgM. Confirmed positive samples were further characterized by serotyping, envelope (E) gene sequencing, and phylogenetic analysis using the maximum likelihood method. Results: The DENV NAT reagent demonstrated consistent detection of 40 copies/mL controls in individual donor (ID)-NAT test (mean CT: 35.61±0.40). During the 63-day quality control monitoring, DENV detection remained stable (mean CT: 22.53±0.72). The center achieved full marks in EQA assessments for 2023 and 2024. Three reactive pools were identified in initial screening, and subsequent individual testing confirmed three DENV RNA-positive donors (sample numbers: 2401, 2402, and 2403). The confirmatory test results from NCCL were: all five NAT platforms consistently detected DENV RNA in the three samples; for serological tests, 2 samples (2402, 2403) were positive for NS1 antigen, while all three samples were negative for both IgG and IgM antibodies. DENV serotyping reagents identified DENV-2 in all cases, which were further confirmed as DENV-2 Genotype Ⅱ-Cosmopolitan by E gene sequencing. Phylogenetic analysis indicated that samples 2401 and 2402 clustered with Southeast Asian strains (Thailand/MZ636802.1, Laos/PQ775621.1), while sample 2403 closely matched a previously reported local Yunnan strain (PV544686.1). Conclusion: DENV-2 infection was detected among blood donors in Xishuangbanna during the rainy season, indicating concurrent risks of imported and local transmission. We recommend implementing pooled NAT screening for blood donors in high-risk areas during dengue epidemic seasons, along with strengthened laboratory quality control, to enhance blood safety.

Objective:To investigate the effect and safety of the double-cross dressing technique for composite rhytidectomy.Methods:A retrospective analysis was performed on a total of 121 patients with face and neck ageing, who were admitted to the Facial and Neck Plastic Surgery Center, the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences from June 2020 to May 2023, all female with the age ranged 34-72 years old. All the patients underwent a full facial and neck composite rhytidectomy. Immediately after surgery, a double-cross bandaging was applied. The cotton pad was nested on the outer auricle, so that the front of the ear and the back of the ear were the first cross. This cross aimed to accurately pressurized the temporal, buccal region and postauricle flap. The second cross occurred at the radix. It secured composite tissue flap at the zygomatic arch and the buccal fat pad zone. Patient′s external auricle was not compressed after bandaging. The healing and the occurrence of complications were observed.Results:All the patients were satisfied with the comfort of the bandaging, the satisfied rate was 100% (121/121). All the patients had different degrees of periocular and perioral swelling 72 hours after surgery. Conjunctival edema and xanthochromia occurred in 30 patients, and oral mucosal congestion occurred in 25 patients, all of which were spontaneously resolved 2-4 weeks after surgery. Postoperative nursing was easily managed. There were no events such as dressing loosening, blocked draining tubes, and difficulty in replacing tubes. All the patients were followed up for 3-12 months after surgery, the flap in the postauricular area of all patients healed well, and there were no adverse complications such as wound infection, necrosis of the flap in the operative area, and delayed healing of the incision.Conclusion:The double-cross bandaging technique achieves the comfort bandaging and good protection of the face, which is safe and effective.

Objective This study aims to develop an early in-hospital temperature management protocol for heat stroke patients and assess its effectiveness,providing guidance for rapid cooling and precise target temperature control.Methods The protocol was developed through a Delphi expert consultation combined with expert panel meetings.A multi-center,non-randomized,historical control study was conducted,utilizing convenience sampling to select heat stroke patients from the emergency departments of 7 tertiary hospitals in Zhejiang Province,China,between June and August 2024 as an experimental group.The protocol was implemented in this group,while the control group consisted of heat stroke patients treated between June and August 2022,prior to protocol implementation.Cooling rates,target temperature attainment rates,and clinical outcomes were compared between the 2 groups.Results The final protocol included 6 primary indicators,23 secondary indicators,and 56 tertiary indicators.After protocol implementation,the experimental group achieved a cooling rate of 0.08(0.05～0.09)℃/min within 0.5 hours,significantly higher than the control group,which had a rate of 0.04(0.02～0.06)℃/min(P＜0.001).The target temperature attainment rates at 0.5 hours and 2.0 hours were 55.93％and 98.31％,respectively,significantly higher than the rates of 15.87％and 61.11％in the control group(P＜0.001).The mechanical ventilation rate,hospitalization rate,ICU admission rate,and mortality rate in the experimental group were 25.42％,61.02％,44.07％,and 8.47％,respectively.Logistic regression analysis revealed that the early in-hospital temperature management protocol significantly reduced the risk of mechanical ventilation and hospitalization in heat stroke patients,with odds ratios(ORs)of 0.294 and 0.300,respectively(both P＜0.05).Conclusion The developed protocol for early in-hospital temperature management in heat stroke patients is scientific,systematic,and practical.It improves cooling rates and target temperature attainment,thereby enhancing the prognosis of heat stroke patients.

Objective:To compare the efficacy of pars plana vitrectomy (PPV) combined with subretinal or intravitreal injection of Conbercept for the treatment of refractory diabetic macular edema (DME).Methods:A retrospective case control study. From June 2022 to March 2024, 32 eyes of 32 patients with refractory DME diagnosed at The Affiliated Eye Hospital of Nanchang University were included in the study. There were 17 male cases with 17 eyes and 15 female cases with 15 eyes. Age was (57.44±8.99) years old; The duration of diabetes was (12.72±6.11) years. All patients had received regular treatment with anti-vascular endothelial growth factor (VEGF) drugs or corticosteroid drugs for at least 5 times, and had undergone focal retinal laser photocoagulation or panretinal laser photocoagulation, the central macular thickness (CMT) persisted or decreased by less than 50 μm. All affected eyes underwent best-corrected visual acuity (BCVA), intraocular pressure, optical coherence tomography (OCT), microperimetry, and laboratory glycated hemoglobin (HbA1c) testing. BCVA was measured using a standard logarithmic visual acuity chart, and converted to the logarithm of the minimum angle of resolution (logMAR) for statistical analysis. CMT was measured using an OCT device. Microperimetry was performed using an MP-3 microperimeter, recording the mean sensitivity (MS) of the retina within a 12° range of the fovea. The affected eyes were treated with 23G PPV combined with internal limiting membrane peeling and either macular subretinal or intravitreal injection of Conbercept, and were divided into subretinal injection group and the intravitreal injection group, each consisting of 16 cases and 16 eyes. The same equipment and methods as before surgery were used for related examinations at 1, 3, and 6 months post-surgery. Changes in BCVA, CMT, and MS were observed and compared, as well as the number of additional anti-VEGF treatments required within 6 months after surgery. Intergroup comparisons were made using independent samples t tests, and repeated measures data were analyzed using repeated measures analysis of variance. Results:The age ( t=-0.271), gender composition ( χ2=0.001), duration of diabetes ( Z=-0.868), HbA1c ( t=-0.789), intraocular pressure ( t=1.689), logMAR BCVA ( t=1.393), CMT ( t=-0.613), MS ( Z=-0.132), and the number of anti-VEGF injections ( t=-0.752) between the subretinal injection group and the intravitreal injection group showed no statistically significant differences ( P>0.05). The within-subject effects comparison of BCVA, CMT, and MS at 1, 3, and 6 months post-surgery compared to pre-surgery for all affected eyes showed statistically significant differences ( F=8.060, 125.722, 39.054; P<0.05). The overall comparison of logMAR BCVA between the subretinal and intravitreal injection groups post-surgery showed no statistically significant difference ( F=0.662, P=0.422), however, comparisons of CMT ( F=4.540) and MS ( F=6.066) showed statistically significant differences ( P<0.05). At 1, 3, and 6 months post-surgery, comparisons of logMAR BCVA between the two groups showed no statistically significant differences ( t=-0.123, 0.239, 1.087; P>0.05), comparisons of CMT showed statistically significant differences ( t=-3.474, -4.832, -2.482; P<0.05), comparisons of MS showed statistically significant differences at 1 and 3 months ( t=-2.940, -2.545; P<0.05), but not at 6 months ( t=-1.527, P>0.05). At 6 months post-surgery, the number of additional intravitreal anti-VEGF injections required in the subretinal and intravitreal injection groups showed a statistically significant difference ( Z=-2.033, P=0.042). During the follow-up period and at the final follow-up, no complications such as injection site bleeding, retinal detachment, vitreous hemorrhage, macular hole, or retinal pigment epithelial tear or atrophy occurred in all affected eyes. Conclusion:Compared with intravitreal injection, subretinal injection of Conbercept for the treatment of refractory DME has more advantages in reducing macular edema and improving visual function in the macular area, and also reduces the number of postoperative anti-VEGF drug treatments.

Renal artery stenosis(RAS)is a common disease that endangers human health,usually caused by ath-erosclerosis or fibromuscular dyspalsia.RAS is also one of the most common causes of secondary hypertension,often leading to resistant hypertension with markedly elevated renin levels and early onset of progressive renal insufficiency.In addition,the activation of renin-angiotensin-aldosterone system(RAAS)caused by RAS and pathophysiological changes in-cluding glomerular sclerosis and atrophy,water and sodium retention can also lead to cardiovascular events such as heart failure,pulmonary edema,coronary heart disease and cerebral infarction.Therefore,early recognition of RAS and prompt revascularization in patients with severe stenosis are key to the treatment of RAS.Percutaneous renal artery stenting(PRAS)has become the preferred revascularization for patients with RAS due to its high response rate,minimally invasive-ness,fast recovery and low restenosis rate.However,there are still some unavoidable complications of PRAS,such as aortic dissection,renal artery rupture,puncture vascular aneurysm,contrast allergy and contrast-induced nephropathy.The occurrence of these complications may have adverse consequences for patients,and even death in severe cases.Renal arteriovenous fistula is a very rare complication of PRAS,and clinical experience in its recognition and management is very limited.Few cases that can be collected tend to favor re-surgical intervention.But surgical intervention undoubtedly in-creases the risk of patient suffering and mortality again.Thus,it is of great significance to summarize such complications and give a scientific recommendation to clinicians.This article reports a patient with resistant hypertension who underwent renal arteriography showing severe stenosis of renal vessels and developed a renal arteriovenous fistula after stent implanta-tion.Therefore,it is worth considering whether the renal arteriovenous fistula caused by PRAS should be treated with sur-gical intervention or conservative medical treatment.

Objective:To evaluate the clinical features of dystonia in patients with different types of atypical Parkinson syndrome (APS).Methods:A total of 104 patients with APS admitted in the Department of Neurology, Beijing Hospital from January 2015 to June 2023 were enrolled in the study, including 57 cases of multiple system atrophy (MSA), 38 cases of progressive supranuclear palsy (PSP) and 9 cases of corticobasal degeneration (CBD). Among 104 cases there were 63 males (60.6%), the mean age of patients was (62.3±8.9) years (54 to 73 years). The sex, age at onset, disease duration, first symptom, clinical features of dystonia and other neurological signs, response to levodopa therapy, numbers of Hoehn & Yahr scale≥3 after 3 years of disease, and MRI findings were documented in patients with different type APS.Results:The overall frequency of dystonia in this series was 45.2%(47/104), and 33.3% (19/57) for MSA group, 50.0% (19/38) for PSP group, 9/9 for CBD group. The types of dystonia were anterocollis, retrocollis, blepharospasm, oromandibular, foot/limb dystonia, Pisa syndrome and myoclonus. In all 47 cases presenting dydtonia, dystonia was not the first complaint and it did not respond to levodopa therapy.Conclusion:In this series of atypical Parkinson syndrome, dystonia is a common feature of the disease, while it is not the first symptom at disease onset, and usually does not respond to levodopa therapy.
