Allergic rhinitis （AR） is one of the most common chronic non-infectious inflammatory diseases in children. Traditional Chinese medicine （TCM） employs a comprehensive therapeutic system integrating treatment by stages and syndrome differentiation and treatment， demonstrating significant advantages in the management of pediatric AR. This article systematically reviews the clinical treatment methods and underlying mechanisms of TCM for pediatric AR in recent years. It is found that internal therapies （such as herbal formulas or Chinese patent medicines like Xiaoqinglong decoction， Yiqi tuomin decoction）， external therapies （including intradermal needles， acupoint application， tuina， and herbal nasal therapy）， as well as combined internal and external approaches （oral herbs combined with acupoint application）， have demonstrated significant effects in alleviating clinical symptoms， improving immune indicators， and reducing recurrence rates in children with AR. The underlying mechanisms are primarily associated with the regulation of signaling pathways such as Toll-like receptor/nuclear factor-kappa B and mitogen-activated protein kinase， thereby modulating immune balance， suppressing inflammatory responses， inhibiting pyroptosis， reducing mucus secretion， and promoting nasal mucosal repair.

OBJECTIVES: Stress urinary incontinence (SUI) is a common condition among women that severely impairs quality of life. Pelvic floor proprioceptive training (PFPT) has attracted increasing attention for its potential to enhance pelvic floor muscle function and alleviate SUI symptoms. This study aims to observe and compare the clinical efficacy of PFPT combined with electroacupuncture, electrical stimulation, and biofeedback therapy versus conventional therapy consisting of electroacupuncture, electrical stimulation, and biofeedback alone in women with SUI, and to explore the role of PFPT in improving symptom and functional outcomes. METHODS: In this randomized controlled trial, 72 women with mild to moderate SUI were recruited from the Department of Rehabilitation Medicine at Third Xiangya Hospital, Central South University, between December 2021 and October 2023. Participants were randomly assigned to an experimental group (n=36) or a control group (n=36). Both groups received health education. The control group underwent electroacupuncture combined with electrical stimulation and biofeedback therapy, while the experimental group additionally received PFPT 3 times per week for 4 weeks. The primary outcome was assessed using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). Secondary outcomes included pelvic floor muscle strength, bladder neck mobility, and balance ability. The ICIQ-SF was reassessed at 1, 3, 6, and 12 months post-treatment. RESULTS: Both groups showed statistically significant improvements in all parameters after treatment (all P<0.05). However, there were no statistically significant differences between groups in most measures (all P>0.05). The experimental group demonstrated longer single-leg stance duration with eyes closed than the control group (left leg: P=0.026; right leg: P=0.006), with a significant increase from baseline (P<0.001). At 6 months post-treatment, the cure rate in the experimental group was significantly higher than that in the control group (P=0.037). CONCLUSIONS Conventional therapy effectively improves SUI symptoms, but adding PFPT provides notable additional benefits, including enhanced balance ability and sustained mid-term cure rates. These findings suggest that PFPT is a valuable adjunct to standard SUI management strategies.

Hepatocellular carcinoma （HCC） is one of the most common malignant tumors with high incidence and mortality rates worldwide， which brings a huge burden to the physical and mental health and socio-economic life of patients. The adenosine monophosphate-activated protein kinase （AMPK） signaling pathway serves as the regulatory center of cellular energy metabolism and is closely associated with the biological activities of HCC cells， including autophagy， apoptosis， and angiogenesis， and it has become a hot topic in current cancer research. Traditional Chinese medicine drugs are abundant in natural components such as flavonoids， alkaloids， and phenols and have the characteristics of multiple targets， pathways， components， and hierarchies. By targeting the AMPK signaling pathway， these components can be used alone or in combination with conventional antitumor therapies to exert an anti-tumor effect on HCC from various aspects. This article reviews and summarizes the extracts of traditional Chinese medicine that target the AMPK signaling pathway for the prevention and treatment of HCC， in order to provide a theoretical basis and a reference for the clinical application of traditional Chinese medicine in the treatment of HCC and the development of related drugs.

Objective To evaluate the efficacy and safety of botulinum toxin A (BTX-A) injection into the external urethral sphincter in combination with sacral neuromodulation (SNM) for the treatment of idiopathic non-obstructive urinary retention (INOUR). Methods A total of 57 INOUR patients treated in our hospital during May 2022 and May 2024 were enrolled. Patients were divided into the BTX (n=30) and combined groups (n=27) according to whether they chose SNM after BTX-A injection. The baseline, postoperative 1-month and 6-month consecutive 3-day voiding diaries, quality of life score (QoL), and post-void residual (PVR), preoperative and postoperative 1-month urodynamic results, and postoperative complications were recorded and compared between the two groups. Results One month after surgery, the average number of voiding frequency per day and PVR were lower in both groups than those before surgery (P<0.05), while the average daily urine volume and maximum flow rate (MFR) were higher (P<0.05). There was no statistically significant difference between the maximum detrusor pressure during micturition in both groups before and after surgery (P>0.05). One month after surgery, the average number of voiding frequency per day, average daily urine volume, PVR, QoL, MFR, bladder compliance (BC), and maximum cystometric capacity (MCC) were better in the combined group than in the BTX group (P<0.05), and the efficiency was higher in the combined group (88.9% vs.63.3%, P<0.05). Six months after surgery, the efficacy of the BTX group returned to the baseline level with no statistically significant difference, whereas the efficacy of the combined group was stable (not different from the postoperative 1-month indicators, but better than the baseline level). During the follow-up, there was no difference in the incidence of complications between the BTX group and combined group [43.3% (13/30) vs. 48.1% (13/27), P>0.05]. Conclusion BTX-A injection into the external urethral sphincter combined with SNM improves the short-term outcomes of INOUR patients and maintains the efficacy 6 months postoperatively, which is a safe and reliable treatment option.

Needle-free injection technology (NFIT) refers to the drug delivery systems in which drugs are propelled as high-speed jet streams using any of the pressure source to penetrate the skin to the required depth. NFIT is a promising drug delivery system as it enables the injection of liquids, powders, and depot/projectiles, and has the advantages of preventing needle stick accidents, improving drug bioavailability, eliminating needle-phobia, increasing vaccine immunity, simplifying operations and is convenient for patients to use. NFIT and its research background, the structure and classification of needle-free jet injectors (NFJI), drugs that can be delivered using NFJI and the factors affecting the injection effect are comprehensively reviewed in this paper. The limitations and potential development directions are summarized to provide a theoretical basis for the application and development of NFIT.

Objective To investigate the therapeutic effect and mechanism of Chaihu Guizhi Ganjiang Decoction on non-alcoholic fatty liver disease(NAFLD)rats.Methods The experiment was conducted in five groups:normal group,model group,low-and high-dose groups of Chinese medicine(Chaihu Guizhi Ganjiang Decoction)and GSK872[receptor interacting protein kinase(RIP)3 inhibitor]group.Except for the normal group,the NAFLD rat model was constructed using high-fat chow feeding method in the remaining groups,respectively.At the end of treatment,hepatocyte apoptosis was observed by terminal transferase uridyl nick end labeling(TUNEL)method,and serum levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST),lipids[total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C)],and the levels of inflammatory factors tumor necrosis factor α(TNF-α)and interleukin 1β(IL-1β)in liver tissues were measured by enzyme-linked immunosorbent assay(ELISA);and the levels of phosphorylation of RIP1,RIP3,and mixed lineage kinase structural domain-like protein(MLKL)were detected in liver tissues by Western Blot.Results Compared with the normal group,the apoptotic index of rat hepatocytes in the model group was elevated,ALT and AST in serum were significantly elevated,TC,TG and LDL-C levels were significantly elevated,and HDL-C level was significantly reduced,and the contents of TNF-α and IL-1β as well as the phosphorylated expression levels of RIP1,RIP3 and MLKL were significantly elevated in the liver tissues(P＜0.05);compared with the model group,the apoptotic index of hepatocytes in rats in the low-and high-dose groups of Chinese medicine and GSK872 group was reduced,the serum levels of ALT and AST were significantly reduced,the levels of TC,TG and LDL-C were significantly reduced,the level of HDL-C was significantly increased,and the contents of TNF-α and IL-1β and the phosphorylated expressions of RIP1,RIP3 and MLKL in the liver tissues were significantly reduced(P＜0.05);there was no significant difference in the above-mentioned indexes between the low-dose and high-dose groups of Chinese medicine and the GSK872 group(P＞0.05).Conclusion Chaihu Guizhi Ganjiang Decoction can effectively improve NAFLD in rats,and its mechanism may be related to the inhibition of RIP1/RIP3/MLKL signaling pathway activation,which in turn inhibits necrotic apoptosis.

Objective To investigate the relationship between two-lung ventilation (TLV) with single-lumen endotracheal tube (SLT), one-lung ventilation (OLV) with double-lumen endotracheal tube (DLT) and postoperative pulmonary complications (PPCs) after total thoracoscopic cardiac surgery. Methods The clinical data of patients who underwent totally thoracoscopic cardiac surgeries in the Guangdong Provincial People’s Hospital from October 2019 to October 2021 were retrospectively analyzed. The patients were divided into 2 group according to the type of endotracheal tube, including a SLT group and a DLT group. Baseline data, surgical variables and PPCs were compared. The influencing factors of PPCs in the two groups were analyzed by binary logistic regression analysis. Results Finally 349 patients were enrolled, including 180 males and 169 females with an average age of (50.0±14.8) years. There were 219 patients in the SLT group and 130 patients in the DLT group. There was no statistical difference in baseline data, surgical variables or PPCs between the two groups (P＞0.05). Binary logistic regression analysis showed that PPCs were related to body mass index in the SLT group (OR=0.778, 95%CI 0.637 to 0.951, P=0.014) and preoperative smoking history in the DLT group (OR=0.058, 95%CI 0.004 to 0.903, P=0.042). Conclusion For the patients who undergo totally thoracoscopic cardiac surgery, TLV with SLT and OLV with DLT show no significant association with PPCs. At the same time, PPCs are associated with body mass index in the SLT group, while associated with preoperative smoking history in the DLT group.

Objective To construct a 3D printed PLLA/β-tricalcium(PLLA/β-TCP)bone tissue engineering scaffold surface porous structure through simple treatment with NaOH solution,increase the roughness and hydrophilicity of the scaffold,and promote cell adhesion on the scaffold surface.Methods The PLLA/β-TCP mesh scaffold was prepared by 3D printing melt deposition molding technology,and the scaffold was roughed by NaOH etching.The effects of NaOH concentration and time on the scaffold were observed according to the microstructure,energy spectrum,contact angle,mechanics,and cell adhesion of the scaffold.Results The PLLA/β-TCP composite scaffold constructed by melt deposition technology had a pre-set porous structure,and the pores were interconnected.After NaOH etching,a porous structure with both macroscopic and microscopic pores was formed.The increase in any of the NaOH concentration and time parameters would lead to the increase of pore diameter and surface roughness.When the NaOH treatment parameter was 0.1 mol/L(9 h),it could significantly reduce the water contact angle on the surface of the scaffold,and had no significant effect on the compressive strength of the scaffold.In vitro cell testing showed that the surface porous composite scaffold etched with NaOH had more advantages in the adhesion and proliferation of BMSCs.Conclusion Using NaOH to process 3D printing of PLLA/β-TCP bone tissue engineering scaffolds can effectively improve the surface morphology of the scaffold,and optimize its hydrophilicity and cell adhesion.
