ObjectiveTo explore the pathological mechanism-syndrome-treatment patterns of approved Chinese patent medicines （CPMs） that treat collateral disorders， providing a reference for the principle of "treating different diseases with the same therapy" in collateral pathology. MethodsCPMs that apply treatment strategies based on collateral disorders were identified from the Pharmacodia database by extracting information from the "efficacy" or "indications" sections of drug package inserts. A database was established to extract the names and compositions of the CPMs， as well as their indications， related traditional Chinese medicine （TCM） symptoms， disease locations （affected areas）， and pathological factors. Frequency statistics were performed. Using the Apriori algorithm， an association rule analysis was conducted on CPMs and disease-location combinations related to the top three most frequent pathological factor combinations. Core formulas for these combinations were identified and analyzed through drug network analysis and MCODE module clustering. ResultsA total of 660 CPMs targeting collateral disorders were retrieved， involving 299 indications， 323 TCM symptoms， 21 disease locations， 19 pathological factors， and 124 pathological factor combinations. The most frequent pathological factor combinations were blood stasis （involved in 109 CPMs， 16.52%）， exogenous wind （外风） -cold-dampness （involved in 43 CPMs， 6.52%）， and qi deficiency-blood stasis （involved in 42 CPMs， 6.36%）. Analysis of the core formulas for these combinations revealed common ingredients such as Honghua （Carthami Flos）， Chuanxiong （Chuanxiong Rhizoma）， Danggui （Angelicae Sinensis Radix）， and Dilong （Pheretima）. ConclusionCollateral disorders involve a wide range of pathogenesis and represent a fundamental mechanism in the onset and development of various diseases， characterized by obstruction and stagnation. The primary therapeutic principle is unblocking of the collaterals. Blood stasis obstructing the collaterals is the core pathological basis， and the strategy of activating blood circulation and resolving stasis to unblock the collaterals should be central to the treatment. The core medication pattern involves combining blood-activating and stasis-resolving herbs with insect-derived medicinals that unblock collaterals. Exogenous wind is often the initiating patholo-gical factor in colla-teral disorders， and the appropriate addition of wind-dispelling herbs can enrich the treatment strategies for such conditions.

Objective:To discuss the clinical efficacy of low-temperature radiofrequency ablation assisted by endoscopy combined with resection and drainage of cervical abscess for the treatment of congenital pyriform sinus fistula （CPSF） in the acute inflammatory period of children. Methods:Clinical data of 30 patients with CPSF in the acute inflammatory period who received low-temperature radiofrequency ablation assisted by endoscopy under laryngoscope, combined with resection and drainage of cervical abscess, from January 2018 to December 2023 were reviewed. After the operation, patients were followed up closely at different stages. All patients underwent color Doppler ultrasound and electronic laryngoscopy, and the results were analyzed. Results:All 30 children successfully completed the surgery without pharyngeal fistula, dysphagia, perifistula, or distal fistula infection, and the incision in the neck healed well. The follow-up survey ranged from 6 months to 2 years, and no recurrences were observed. Conclusion:Low-temperature radiofrequency ablation assisted by endoscopy combined with resection and drainage of cervical abscess is a promising method for treating CPSF in the acute inflammatory period. It is less traumatic, simple, safe, has a significant curative effect, and a low recurrence rate. This approach can be used as a supplementary operation for CPSF in children and provides a new way for clinical treatment.

The pharmaceutical industry faces challenges in quality digitization for complex multi-stage processes, especially in small-sample systems. Here, an intelligent quality prediction and diagnostic (IQPD) framework was developed and applied to Tong Ren Tang's Niuhuang Qingxin Pills, utilizing four years of data collected from four production units, covering the entire process from raw materials to finished products. In this framework, a novel path-enhanced double ensemble quality prediction model (PeDGAT) is proposed, which combines a graph attention network and path information to encode inter-unit long-range and sequential dependencies. Additionally, the double ensemble strategy enhances model stability in small samples. Compared to global traditional models, PeDGAT achieves state-of-the-art results, with an average improvement of 13.18% and 87.67% in prediction accuracy and stability on three indicators. Additionally, a more in-depth diagnostic model leveraging grey correlation analysis and expert knowledge reduces reliance on large samples, offering a panoramic view of attribute relationships across units and improving process transparency. Finally, the IQPD framework integrates into a Human-Cyber-Physical system, enabling faster decision-making and real-time quality adjustments for Tong Ren Tang's Niuhuang Qingxin Pills, a product with annual sales exceeding 100 million CNY. This facilitates the transition from experience-driven to data-driven manufacturing.

Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.

Objective:To analyze the clinical features, treatment and prognosis of clear cell sarcoma of kidney (CCSK) in children.Methods:A retrospective case series study was conducted on 12 children with CCSK who were admitted to the Department of Hematology and Oncology, Children′s Hospital, the First Affiliated Hospital of Zhengzhou University from January 2014 to December 2021.The clinical characteristics, diagnosis and treatment process, and follow-up results were summarized, and the survival rate was calculated using the Kaplan-Meier method.Results:Among the 12 patients, 10 were males, and 2 were females, with the age of onset of 2.8 (1.0-5.7) years.CCSK originated from the left kidney in 6 patients and from the right kidney in 6 patients.All the patients underwent complete resection of the tumor, including 2 patients in stage Ⅰ, 4 patients in stage Ⅱ, 3 patients in stage Ⅲ, and 3 patients in stage Ⅳ; and 12 children received the corresponding chemotherapy regimen, 6 cases received radiotherapy.During the follow-up of 56 (19-94) months to December 31, 2023, 4 cases died of disease recurrence, and 8 cases survived without disease.The 5-year event-free survival rate was (62±11)%, and the 5-year overall survival rate was (72±9)%.Conclusions:Pediatric CCSK is more common in male children.The combination of radical surgery and postoperative chemoradiotherapy offers a good prognosis in the early stage, while the mortality of patients due to recurrence and distant metastasis is high.

Purpose To explore the clinical and pathologi-cal features and the relationships between pathological features and drugs of patients with drug-induced liver injury(DILI)based on the hepatotoxicity injury patterns.Methods The clin-ical data,laboratory indicators,drugs,and liver biopsy of 50 cases of DILI were collected,the expression of CK19 was detec-ted by immunohistochemistry EnVision two-step method,and the reticular scaffold of liver tissue was displayed by Reticular fiber staining.Results Among the 50 patients with DILI,there were 29 cases of hepatocellular DILI,11 cases of cholestatic DILI,and 10 cases of mixed DILI,respectively,with the hepatocellu-lar DILI accounting for the highest proportion(58％).7 catego-ries of drugs induced DILI,with herbal ranking first(52％).Different types of drugs could cause different types of DILI,with herbal induced 17 cases hepatocellular DILI(58.62％)and an-ti-infectious and anticancer drugs induced all 3 cases cholestatic DILI(27.27％).Different types of DILI displayed various pathological characteristics.Hepatocellular congestion,feathery degeneration,and small bile duct thrombosis primarily occur in cholestasis and mixed DILI,while bridging necrosis,sub-large and large necrosis were mainly seen in hepatocellular DILI.Conclusion Based on hepatotoxicity injury patterns,DILI ex-hibits a variety of clinical and pathological characteristics,and there is some relationship between pathological characteristics and drugs.Liver puncture pathological biopsy plays an important role in improving the diagnosis and treatment of DILI.

The clinical data of one child with metanephric stromal tumor (MST) and BRAF V600E gene mutation admitted to the First Affiliated Hospital of Zhengzhou University in June 2022 was analyzed retrospectively.Literature was reviewed.The patient, a 2-year-old girl, was diagnosed with a tumor in the left abdomen.The maximum diameter of the tumor was 10.5 cm.A radical nephrectomy was performed on the left kidney, and postoperative pathology revealed MST.Microscopically, the tumor had no envelope and exhibited expansive growth.The tumor cells were fusiform or stellate, and nuclear division was visible in the cell-rich region.Dysplastic blood vessels were seen inside the tumor.The tumor cells around the blood vessels and invaginated renal tubules were arranged like onion skin.CD34 was detected positive by immunohistochemical staining, and BRAF V600E mutation was also detected positive by fluorescent polymerase chain reaction.A total of 21 relevant case reports were retrieved, including 16 in English and 5 in Chinese.Fifty-eight MST patients, including the one in this report were analyzed.These patients were aged 2 days to 15 years, with a median age of 2 years.Except for 2 patients with unknown sex, the ratio of male to female was about 1.4∶1.0.Most MST patients were asymptomatic, with an average tumor size of 5.3 cm.The tumor cell CD34 showed positive expression in different degrees.Eight patients received the BRAF V600E mutation detection, and the results were all positive.Fifty-eight patients underwent nephrectomy and were followed up for 0-156 months, of which 7 patients were assisted with radiotherapy and chemotherapy.During the follow-up, 1 patient died, and 1 patient had a relapse.MST is a rare benign renal stromal tumor. BRAF V600E mutations are detected in a variety of malignancies.This paper is the first to report MST with BRAF V600E mutation in China and points out the importance of molecular detection of BRAF mutation for accurate diagnosis of MST.

OBJECTIVE To investigate the effect of dioscin on renal injury in septic rats and its possible mechanism. METHODS The septic rat model was induced by using cecal ligation and puncture. Sixty model rats were randomly divided into model group （0.5% sodium carboxymethyl cellulose solution）， dioscin low-dose， medium-dose and high-dose groups （30， 60， 120 mg/kg） and dexamethasone group （positive control， 10 mg/kg）， with 12 rats per group； another 12 rats were selected as the sham operation group （0.5% sodium carboxymethyl cellulose solution）. After 15 minutes of modeling， rats in each group were injected with medicine/0.5% sodium carboxymethyl cellulose solution via the tail vein. Twenty-four hours after administration， the levels of creatinine （Cr）， blood urea nitrogen （BUN）， neutrophil gelatinase associated lipocalin （NGAL）， kidney injury molecule-1 （KIM- 1）， interleukin 6 （IL-6）， IL-1β and tumor necrosis factor-α （TNF-α） in serum and malondialdehyde （MDA） in renal tissue， superoxide dismutase （SOD） activity and the protein expressions of nuclear factor E2-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1）， NOD-like receptor protein 3 （NLRP3） were detected； renal histomorphology was observed. RESULTS Compared with model group， pathological injury of renal tissue was improved significantly in dioscin low-dose， medium-dose and high-dose groups； the levels of Cr， BUN， NGAL， KIM-1， IL-6， IL-1β and TNF-α in serum， MDA level and protein expression of NLRP3 in renal tissue were decreased significantly （P＜0.05）； SOD activity in renal tissue， protein expressions of Nrf2 and HO-1 were increased significantly （P＜0.05）， in a dose-dependent manner （P＜0.05）. The pathological damage of renal tissue in the dioscin high-dose group was similar to dexamethasone group， and there was no statistically significant difference in the levels of the above indicators （P＞0.05）. CONCLUSIONS Dioscin can activate the Nrf2/HO-1 signaling pathway to inhibit NLRP3 inflammasome， and realize the inhibition of inflammatory factors and oxidative stress， so as to protect the kidney injury in sepsis.
