ObjectiveTo observe the clinical effectiveness and safety of Qingfei Shenshi Decoction （清肺渗湿汤） combined with western medicine for patients with bronchial asthma of heat wheezing syndrome， and to explore its potential mechanism of action. MethodsEighty-six participants with bronchial asthma of heat wheezing syndrome were randomly divided into treatment group and control group， each group with 43 participants. The control group received conventional western medicine， and the treatment group was additionally administered Qingfei Shenshi Decoction orally on the basis of the control group， 1 dose per day. Both groups were treated for 14 days. The primary outcome measure was clinical effectiveness； secondary outcome measures included traditional Chinese medicine （TCM） syndrome score， asthma control test （ACT） score， pulmonary function indices such as forced expiratory volume in 1 second （FEV₁）， forced vital capacity （FVC）， peak expiratory flow （PEF）， serum inflammatory factor levels including interleukin-4 （IL-4）， tumour necrosis factor-α （TNF-α）， and high-sensitivity C-reactive protein （hs-CRP）， and immune function indices including CD3⁺， CD4⁺， CD8⁺， CD4⁺/CD8⁺. All outcome measures were evaluated before and after treatment. Vital signs were monitored， and electrocardiography， blood routine， urine routine， liver function， and renal function tests were performed before and after treatment. Adverse events and reactions during the study were recorded. ResultsA total of 80 patients completed the trial with 40 in each group. The total clinical effective rate of the treatment group was 97.5% （39/40）， which was significantly higher than that of the control group （85.0%， 34/40， P＜0.05）. After treatment， both groups showed decreased TCM syndrome scores， IL-4， TNF-α， hs-CRP， and CD8⁺ levels， as well as increased ACT scores， CD3⁺， CD4⁺， CD4⁺/CD8⁺， FEV₁， FVC， and PEF levels （P＜0.05 or P＜0.01）. Moreover， the improvements in these indices were more significant in the treatment group than in the control group （P＜0.05 or P＜0.01）. No significant abnormalities in safety indicators were observed in either group， and no adverse events or reactions occurred. ConclusionQingfei Shenshi Decoction combined with conventional western medicine for patients with bronchial asthma of heat wheezing syndrome can effectively improve the clinical symptoms， pulmonary function， and clinical effectiveness， with good safety. Its mechanism may be related to reducing inflammatory factor levels and regulating T lymphocyte subsets to improve immune function.

OBJECTIVE: To explore the potential effects and mechanisms of Liang-Ge-San (LGS) for the treatment of acute respiratory distress syndrome (ARDS) through network pharmacology analysis and to verify LGS activity through biological experiments. METHODS: The key ingredients of LGS and related targets were obtained from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform. ARDS-related targets were selected from GeneCards and DisGeNET databases. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses were performed using the Metascape Database. Molecular docking analysis was used to confirm the binding affinity of the core compounds with key therapeutic targets. Finally, the effects of LGS on key signaling pathways and biological processes were determined by in vitro and in vivo experiments. RESULTS: A total of LGS-related targets and 496 ARDS-related targets were obtained from the databases. Network pharmacological analysis suggested that LGS could treat ARDS based on the following information: LGS ingredients luteolin, wogonin, and baicalein may be potential candidate agents. Mitogen-activated protein kinase 14 (MAPK14), recombinant V-Rel reticuloendotheliosis viral oncogene homolog A (RELA), and tumor necrosis factor alpha (TNF-α) may be potential therapeutic targets. Reactive oxygen species metabolic process and the apoptotic signaling pathway were the main biological processes. The p38MAPK/NF-κ B signaling pathway might be the key signaling pathway activated by LGS against ARDS. Moreover, molecular docking demonstrated that luteolin, wogonin, and baicalein had a good binding affinity with MAPK14, RELA, and TNF α. In vitro experiments, LGS inhibited the expression and entry of p38 and p65 into the nucleation in human bronchial epithelial cells (HBE) cells induced by LPS, inhibited the inflammatory response and oxidative stress response, and inhibited HBE cell apoptosis (P<0.05 or P<0.01). In vivo experiments, LGS improved lung injury caused by ligation and puncture, reduced inflammatory responses, and inhibited the activation of p38MAPK and p65 (P<0.05 or P<0.01). CONCLUSION LGS could reduce reactive oxygen species and inflammatory cytokine production by inhibiting p38MAPK/NF-κ B signaling pathway, thus reducing apoptosis and attenuating ARDS.

Alcohol is a high-risk factor of the head and neck tumor, and acetaldehyde dehydrogenase type 2（ALDH2） is an important alcohol metabolism enzyme in the human body, whose function is to metabolize acetaldehyde into non-toxic acetic acid in the human body. Studies have shown that ALDH2 gene polymorphisms increase the risk of head and neck tumors by affecting enzyme activity to regulate the rate of alcohol metabolism in the body, and high levels of ALDH2 expression are beneficial for enhancing head and neck tumor immunity and improve prognosis. This article aims to review the research progress on the relationship between ALDH2 and the occurrence and treatment of head and neck tumors.

Objective:Traditional salivary gland surgery involves incisions in the visible facial and cervical regions, leaving postoperative scars that affect cosmesis. This study aims to investigate the clinical efficacy, safety, and application value of robot-assisted endoscopic resection of benign submandibular and parotid gland lesions via a postauricular approach, while clarifying its advantageous differences compared with endoscopic surgery. Methods:Clinical data of 23 patients who underwent robot-assisted endoscopic surgery via a postauricular approach（11 parotid gland cases and 12 submandibular gland cases） from January 2017 to February 2025 were retrospectively analyzed. Meanwhile, A matched control group of patients who received postauricular endoscopic surgery during the same period was selected as the control group in a 1∶1 ratio（11 parotid gland cases and 12 submandibular gland cases）. Indicators such as operation time, intraoperative blood loss, complications, and postoperative aesthetic satisfaction scores（Numeric Satisfaction Scale, NSS） were collected and compared between the two groups. The inclusion criteria were limited to benign lesions of the parotid superficial lobe（diameter ≤5 cm, without deep lobe involvement） and benign submandibular gland lesions（diameter ≤4 cm, without extension through the mylohyoid muscle）. Results:All robot-assisted surgeries were successfully completed without conversion to open surgery. In the robot group, there were 7 male patients（mean age 39.5 years） and 16 female patients（mean age 35.9 years）. For parotid gland surgeries, the mean operation time was （114.00±38.35） minutes. For submandibular gland surgeries, the mean operation time was（140.00±30.75） minutes.Temporary facial paralysis occurred in 0 of patients after robotic submandibular gland surgery （vs.8% in the endoscopic group） and 18% after robotic parotid gland surgery （vs.27 % in the endoscopic group）,all of which resolved within 1 month, with no occurrence of salivary fistula or infection. Patients had high aesthetic satisfaction（NSS scores: 8.90±1.20 for parotid surgeries and 9.00±0.70 for submandibular surgeries）. No tumor recurrence was observed during the 8-77 month follow-up period. Conclusion:Robot-assisted endoscopic salivary gland surgery via a postauricular approach is safe and feasible. With three-dimensional high-definition visualization and precise mechanical manipulation, it outperforms traditional endoscopic surgery in reducing blood loss, lowering the risk of nerve injury, and achieving long-term cosmetic outcomes. It is particularly suitable for young patients and cases with benign lesions of the parotid superficial lobe or submandibular gland that have high aesthetic demands. However, this surgical approach is not suitable for deep parotid lobe tumors, and its long-term efficacy requires verification through large-sample studies.

Acute pancreatitis (AP) is a life-threatening gastrointestinal disorder for which no effective pharmacological treatments are currently available. One of the pharmacological targets that merits further research is the neurokinin 1 receptor (NK1R), which is found on pancreatic acinar cells and responds to the neuropeptide substance P (SP) that participates in AP. Although a few studies have stated the involvement of SP/NK1R in neurogenic inflammation in AP development, the regulatory mechanism remains unclear. In this study, we found that following activation of NK1R by SP, β-arrestin1, a scaffold protein of NK1R, down-regulated transcription of Adss, Adsl, and Ampd in the purine nucleotide cycle, thereby inhibiting mitochondrial function through fumarate depletion. Interestingly, we identified magnolol as a new and natural NK1R inhibitor with a non-nitrogenous biphenyl core structure. It exhibited a beneficial effect on AP by restoring purine nucleotide cycle metabolic enzymes and fumarate levels. Our study not only provides new therapeutic strategies, leading compounds, and drug translation possibilities for AP, but also provides important clues for the study of downstream mechanisms driven by SP in other diseases.

Alzheimer's disease (AD) is characterized by cognitive and functional deterioration, with pathological features such as amyloid-beta (Aβ) aggregates in the extracellular spaces of parenchymal neurons and intracellular neurofibrillary tangles formed by the hyperphosphorylation of tau protein. Despite a thorough investigation, current treatments targeting the reduction of Aβ production, promotion of its clearance, and inhibition of tau protein phosphorylation and aggregation have not met clinical expectations, posing a substantial obstacle in the development of drugs for AD. Recently, artificial intelligence (AI), computational biology (CB), and systems biology (SB) have emerged as promising methodologies in AD research. Their capacity to analyze extensive and varied datasets facilitates the identification of intricate patterns, thereby enriching our comprehension of AD pathology. This paper provides a comprehensive examination of the utilization of AI, CB, and SB in the diagnosis of AD, including the use of imaging omics for early detection, drug discovery methods such as lecanemab, and complementary therapies like phototherapy. This review offers novel perspectives and potential avenues for further research in the realm of translational AD studies.

OBJECTIVE: To summarize research progress on enhanced recovery after posterior cruciate ligament (PCL) reconstruction, clarify the core contradictions, effective intervention methods, and evaluation shortcomings in current clinical practice, and provide theoretical support for optimizing clinical rehabilitation strategies. METHODS: Relevant domestic and international literature in recent years was systematically searched. The key technologies and challenges for enhanced recovery after PCL reconstruction were analyzed from three aspects: the core issues of enhanced recovery after PCL reconstruction, treatment strategies, and the post-reconstruction effectiveness evaluation system. RESULTS: Enhanced recovery after PCL reconstruction mainly faces two core problems. First, there is a balance dilemma between graft tendon protection and knee joint function recovery: the tensile capacity of the graft tendon is weak in the early postoperative period, so excessive weight-bearing easily leads to relaxation, while overly conservative immobilization causes muscle atrophy and joint adhesion. Second, the return-to-sport rate is significantly affected by injury type and treatment method: patients with combined multiple ligament or meniscus injuries have a much lower return-to-sport rate than those with isolated PCL injury, and the risk of return-to-sport failure is higher. Current research mainly promotes rehabilitation from two aspects: physical therapy and surgical technology. Physical therapy runs through the perioperative period: preoperatively, muscle strength training, swelling control, and maintenance of joint range of motion are used to optimize surgical conditions; postoperatively, phased intervention is implemented. Surgical technology focuses on minimally invasive and anatomical approaches: arthroscopic surgery reduces injury, double-bundle reconstruction and internal tension-relief technology improve stability, and modified tunnel positioning and special surgical methods avoid the risk of "Killer Turn". Postoperative functional evaluation adopts multi-dimensional indicators: subjective evaluation relies on scales such as Lysholm and International Knee Documentation Committee (IKDC); objective evaluation assesses stability through Telos stress test and posterior drawer test; imaging evaluation takes MRI as the core; psychological evaluation is assisted by the Tampa scale of kinesiophobia-11 (TSK-11). However, there are obvious shortcomings, such as the lack of PCL-specific evaluation tools. CONCLUSION Enhanced recovery after PCL reconstruction requires the integration of precise surgery, individualized rehabilitation, and comprehensive subjective and objective evaluation. In the future, biomaterials and digital technologies should be integrated to optimize the full-cycle management of PCL reconstruction, thereby improving functional recovery and the effect of return to sports.

OBJECTIVE: To investigate the short-term clinical effect of closed reduction single arm external fixator combined with percutaneous needle fixation in the treatment of C1 distal radius fracture in elderly patients. METHODS: Between December 2022 and December 2023, a total of 60 elderly patients diagnosed with type C1 distal radius fractures were treated, comprising 9 males and 51 females. The age ranged from 65 to 84 years old, with an average of (72.69±8.14) years old. Among them, there were 18 cases on the left side and 42 cases on the right side. There were 55 cases of falling injury and 5 cases of traffic accident injury. According to the different surgical methods, the patients were divided into observation group and control group, with 30 cases in each group. The control group underwent manual reduction and unilateral external fixator fixation, consisting of 4 males and 26 females. The mean age was (72.54±8.67) years old. The body mass index (BMI) was (20.61±2.17) kg·m^-2. There were 10 cases on the left side and 20 cases on the right side. Among them, there were 27 cases of falling injury and 3 cases of traffic accident injury. The observation group was treated with manual reduction and unilateral external fixator combined with percutaneous Kirschner wire fixation, including 5 males and 25 females. The mean age was (72.76±7.23) years old. BMI (20.82±2.03) kg·m^-2. The left side was involved in 8 cases and the right side in 22 cases. There were 28 cases of falling injury and 2 cases of traffic accident injury. The changes in radial height, ulnar declination, palmar inclination angle parameters and patient-rated wrist evaluation (PRWE) were assessed on X-ray films before surgery, 2 days after surgery, and 12 weeks after surgery between the two groups. RESULTS: All surgical procedures were successfully completed in both groups without any significant complications. All patients were followed up for a duration from 12 to 20 weeks with an average of(14.50±2.78) weeks. The two groups exhibited significant differences in radial height, palmar inclination angle, and ulnar deviation angle at 2 days and 12 weeks post-operation (P<0.05). However, there was no statistically significant difference observed in radial height, palmar inclination, and ulnar deviation between the two groups at 2 days after the operation (P>0.05). There were significant differences in radial height, palmar inclination angle, and ulnar deviation between the two groups at 12 weeks after operation (P<0.05). At 2 days and 12 weeks after the operation, there were significant differences in PRWE scores of the two groups compared with preoperative scores(P<0.05). At 2 days after the operation, there was no significant difference in PRWE score between the two groups (P>0.05). The PRWE score showed a significant difference between the two groups at 12 weeks post-operation(P<0.05). CONCLUSION The combination of closed reduction and unilateral external fixator, along with percutaneous pin fixation provides move stable fixation for type C1 distal radius fractures. Gradual removal of external fixator further facilitatse the recovery of wrist joint function.

Isolated male epispadias typically presents with preputial defects and dorsal urethral dehiscence. A less common subtype, known as concealed epispadias, is distinguished by an intact prepuce. Despite its clinical relevance, there is limited literature on this variant. In this study, we retrospectively analyzed the clinical data of 86 pediatric patients with isolated male epispadias treated in Beijing Children's Hospital (Beijing, China) from May 2004 to July 2023, including 19 cases of concealed epispadias and 67 of nonconcealed epispadias. We compared clinical characteristics, preoperative diagnostics, surgical techniques, postoperative outcomes, and sexual function during follow-up between the concealed and nonconcealed groups. No significant differences were observed between the two groups regarding surgical methods, postoperative complications, or rates of urinary incontinence. However, notable distinctions were found in the age at initial diagnosis, timing of surgery, frequency of incontinence, location of the urethral meatus, and postoperative urinary incontinence scores (all P < 0.05). Given the absence of penopubic epispadias in concealed cases, we categorized glans and penile epispadias within nonconcealed epispadias as distal epispadias ( n = 40) and subsequently compared them with concealed epispadias cases. The postoperative urinary incontinence scores did not differ significantly between the concealed and distal epispadias groups. These findings suggest that concealed epispadias represents a relatively milder form of the condition, characterized by the absence of penopubic involvement, lower rates of urinary incontinence, and favorable surgical outcomes. However, the intact prepuce in concealed cases underscores the need for careful identification and early diagnosis.
