Objective To explore the traditional Chinese medicine(TCM)syndrome characteristics of patients with Chikungunya hemorrhagic fever and to provide empirical data to support the application of TCM in diagnosing and treating Chikungunya hemorrhagic fever.Methods A cross-sectional survey was conducted to collect clinical data(sex,age,days since onset,and comorbidity underlying disease conditions)and TCM with four-examination information(symptoms,tongue manifestations,and pulse manifestations)from 255 patients with Chikungunya hemorrhagic fever who visited Lecong Hospital of Shunde,Foshan,the Third People's Hospital of Shunde District of Foshan,Shunde Hospital of Southern Medical University Affiliated Chencun Hospital between July 23 and July 29,2025.Factor and cluster analyses were used to summarize TCM syndrome characteristics and analyze core pathogenesis in conjunction with clinical features.Results Among the 255 patients with Chikungunya hemorrhagic fever,131 were male and 124 were female,with a age of(49.05±17.93)years and a disease duration of(3.26±1.78)days.Among the four types of examination information in TCM,35 items exhibited a frequency exceeding 10%.The most prevalent symptoms were arthralgia(180 patients,70.59%),exanthem(153 patients,60.00%),fatigue(99 patients,38.82%),anhidrosis(98 patients,38.43%),pruritus(96 patients,37.65%),and fever(92 patients,36.08%).Tongue and pulse manifestations were primarily white fur(155 patients,60.78%),pink tongue(111 patients,43.53%),slippery pulse(143 patients,56.08%),and greasy fur(134 patients,52.53%).Patients with disease onset≤3 d had a higher incidence of arthralgia,fatigue,fever,aversion to cold,generalized muscle pain,aversion to wind,insomnia,headache,sweating,low-grade fever,poor appetite,loose stool,hyperhidrosis,and red tongue than those with disease onset≥4 d(P<0.05).Patients with disease onset≥4 d had a higher incidence of pink tongue and thick fur than those with disease onset≤3 d(P<0.05).The syndrome elements in patients with Chikungunya hemorrhagic fever predominantly manifested on the defensive exterior,with involvement of the sinew-bone joints,skin-muscle,and spleen.Pathogenic factors were primarily characterized by external winds,dampness,and heat.Factor and cluster analysis result indicated three TCM pathogenesis progression patterns:imbalance of the defensive exterior with wind-dampness conflict and heat transformation;dampness-heat flowing into muscles and meridians causing joint obstruction and qi blood stasis;and dampness-heat congelation resulting in qi mechanism obstruction,consumption of body fluids,and infiltration of the skin.Conclusion Patients with Chikungunya hemorrhagic fever primarily present with fever,joint pain,and rashes.In TCM,this condition falls under the category of"dampness-warmth"syndrome.Its etiology is attributed to pathogens,with transmission occurring through mosquito bites.The core pathogenesis of TCM is the invasion of the defensive exterior and dampness-toxic heat accumulation.The therapeutic principles focus on clearing heat pathogens,resolving dampness pathogens,dispersing wind pathogens,and promoting the resolution of rashes.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

The incidence of pediatric inflammatory bowel disease(IBD)is rising,with an especially high proportion of early-onset cases in Asia.Conventional treatments such as glucocorticoids and immunosuppressants have limited efficacy and notable adverse effects,whereas biologic therapies substantially improve remission rates and quality of life.Therapeutic drug monitoring(TDM),by assessing trough concentrations and anti-drug antibodies,enables individualized dose optimization,reduces immunogenicity,and prolongs treatment persistence.However,challenges remain,including insufficient standardization and the lack of pediatric-specific concentration thresholds.This review summarizes recent advances in biologics and TDM in pediatric IBD to inform precision treatment.

Objective To investigate the influence of different disinfectants on the ultrasound-guided internal jugular vein puncture and adhesive application.Methods A total of 102 emergency patients with traumatic hemorrhage who underwent ultrasound-guided internal jugular vein puncture and catheterization were selected as the study subjects and randomly divided into the iodine group(51 cases)and the chlorhexidine-alcohol group(51 cases).Iodophor(0.5%effective iodine)and 2.0%chlorhexidine gluconate+70.0%ethanol were used for disinfection before puncture,respectively.The disinfection effect of the puncture site,puncture condition,ultrasound imaging,and adhesive force of the application of patients were statistically compared between the two groups.Results There was no significant difference in the bacterial count before disinfection,the bacterial count after disinfection or the qualified rate of disinfection at the puncture site of patients between the two groups(P>0.05).There were significant differences in the success rate of one-time puncture,the number of puncture and the time of puncture and catheterization between the two groups(P<0.05).There were significant differences in the rate of clear ultrasound images,adhesive force and rate of warping or shedding of the application between the two groups(P<0.05).Conclusion For emergency patients with traumatic hemorrhage,using iodophor(0.5%effective iodine)and 2.0%chlorhexidine gluconate+70.0%ethanol disinfection before ultrasound-guided internal jugular vein puncture can achieve good disinfection effects.Iodine disinfection can obtain clearer ultrasound images and a higher success rate of one-time puncture,but the adhesive force of the application is poor,making it prone to warping or shedding.

Objective To investigate the efficacy of Lishui Xiaozhong Granules combined with Conbercept for the treatment of diabetic macular edema(DME).Methods From December 2022 to June 2023,46 patients(46 eyes)with DME of spleen and kidney yang deficiency complicated with blood-stasis obstructing the eye collaterals syndrome admitted to Foshan Hospital of Traditional Chinese Medicine were selected as the study objects.According to the principle of single-blind randomized controlled trial,the patients were randomly divided into treatment group and control group by random number table method,with 23 cases(23 eyes)in each group.The control group was treated with intravitreal injection of Conbercept,and the treatment group was treated with oral use of Lishui Xiaozhong Granules on the basis of treatment for the control group.The course of treatment lasted 3 months and then a follow-up for 6 months was conducted.Before and after treatment,the two groups were observed int the changes of traditional Chinese medicine(TCM)syndrome score,best corrected visual acuity(BCVA,LogMAR),central macular thickness(CMT),mean vessel density(VD)of superficial capillary plexus(SCP)and deep capillary plexus(DCP)in macular area,and the amplitude density and the latency of P1 and N1 wave in the R1 ring of multifocal electroretinogram(mf-ERG).Results(1)After 1,3 and 6 month(s)of treatment,BVCA in the two groups was improved when compared with that at the previous observation time point(P＜0.05),and the improvement in the treatment group was superior to that in the control group after 1,3 and 6 month(s)of treatment(P＜0.01).(2)After 1,3 and 6 month(s)of treatment,the CMT of the two groups was lowered as compared with that at the previous observation time point(P＜0.05),and the decrease in the treatment group was significantly superior to that in the control group(P＜0.01).(3)After 6 months of treatment,SCP-VD and DCP-VD in the two groups showed no obvious changes when compared with those before treatment(P＞0.05),the differences between the two groups after treatment were no statistically significant,either(P＞0.05).(4)After 1,3 and 6 month(s)of treatment,the amplitude densities of P1 wave and N1 wave in the R1 ring of mf-ERG in the two groups were increased when compared with those at the previous observation time point(P＜0.05),and the latency of P1 wave and N1 wave was shortened when compared with that at the previous observation time point(P＜0.05),and the treatment group had stronger effect on increasing the amplitude densities and on shortening the latency than the control group(P＜0.01).(5)After 6 months of treatment,the scores of TCM syndromes in the treatment group were lowered(P＜0.05)while the scores in the control group showed no obvious changes as compared with those before treatment.The intergroup comparison showed that the decrease of TCM syndrome score in the treatment group was significantly superior to that in the control group(P＜0.01).Conclusion In the treatment of DME with spleen and kidney yang deficiency complicated with blood-stasis obstructing the eye collaterals syndrome,Lishui Xiaozhong Granules combined with Conbercept have no influence on improving the SCP-VD and DCP-VD,but the combined therapy exerts satisfactory efficacy on increasing BCVA and on improving macular oedema,retinal function in the macular area and systemic symptoms.
