This article systematically analyzed the historical evolution of the origin， scientific name， producing area， quality evaluation， harvesting and processing， and other aspects of Quisqualis Fructus by consulting the ancient materia medica， medical books， prescription books， local literature and combining with the modern literature and standards， summarized and explored the development rules of its medicinal properties and efficacy along with their underlying causes， in order to provide support for the development and utilization of famous classical formulas containing this herb. According to the textual research， Shijunzi was first recorded as Liuqiuzi in Nanfang Caomuzhuang of the Jin dynasty， and the name of Shijunzi was first used in Kaibao Bencao of the Song dynasty， which has been consistently used throughout subsequent dynasties， and there were also aliases such as Junziren， Sijunzi， and Dujilizi. The mainstream source of Quisqualis Fructus used in the past dynasties has been the dried mature fruits of Quisqualis indica， a plant belonging to the family Combretaceae. In modern times， its variety Q. indica var. villosa has also been recorded as the medicinal material of Quisqualis Fructus. In 2007， the Flora of China（English edition） designated Q. indica var. villosa as a synonym of Q. indica. Today， the accepted name of Shijunzi is updated to Combretum indicum. According to ancient herbal records， the producing areas of Quisqualis Fructus were Guangdong， Hong Kong， Macao， Guangxi， Hainan， Sichuan and Fujian， and then gradually expanded to Yunnan， Taiwan， Jiangxi and Guizhou. Since the Song dynasty， two major production regions have gradually emerged in Sichuan， Chongqing and Fujian. Currently， it is primarily cultivated in Chongqing， Guangxi and other areas， with Chongqing yielding the highest output. Since modern times， superior quality has been defined by large size， a purple-black surface， plump grains， and a yellowish-white kernel. According to ancient herbal records， the harvesting period of Quisqualis Fructus was the July and August of the lunar calendar， mostly used raw after shelling or with the shell intact， it underwent processing methods such as cleaning， slicing， mixing， steaming， roasting， stewing， and frying. Currently， the harvesting period is autumn， followed by sun-drying or low-heat drying， with processing methods including cleaning， stir-frying， and stewing. In ancient and modern literature， the records of the properties， functions and indications of Quisqualis Fructus are basically the same， that is， sweet in taste， warm in nature， predominantly non-toxic， belonging to the spleen and stomach meridians. It possesses effects of insecticide， decontamination and invigorating spleen for ascariasis， enterobiasis， abdominal pain due to worm accumulation and infantile malnutrition.The contraindications for use primarily include avoiding consumption by individuals without parasitic infestations， limiting use for those with spleen-stomach deficiency-cold， refraining from drinking hot tea during medication， and avoiding excessive intake. Based on the textual research， it is suggested that the dried mature fruits of Q. indica should be used as the medicinal material for the development of famous classical formulas containing Quisqualis Fructus. Processing methods may be chosen according to prescription requirements， and the raw products is recommended for medicinal use if not specified.

Chaihu Guizhi Ganjiangtang was first recorded in the Treatise on Cold Damage （Shang Han Lun）. This prescription is composed of Bupleuri Radix， Scutellariae Radix， Cinnamomi Ramulus， Zingiberis Rhizoma， Trichosanthis Radix， Ostreae Concha， and Glycyrrhizae Radix et Rhizoma. It has the effects of soothing Lesser Yang， warming the spleen， and stimulating the generation of body fluid. It is mainly used to treat digestive tract diseases such as chronic cholecystitis （CC）， irritable bowel syndrome， and non-alcoholic fatty liver disease. Dyspepsia caused by CC presents a variety of gastrointestinal symptoms such as abdominal pain， poor appetite， postprandial fullness， aversion to greasy food， soft stool， and bitter mouth， being a type of biliary dyspepsia. In modern medicine， dyspepsia caused by CC is mainly managed by medical treatment and surgical treatment. Internal medicine mainly focuses on reducing inflammation， promoting the function of gallbladder， resolving stones， alleviating spasms， and relieving the pain for CC， demonstrating definite short-term efficacy but suffering from single effects， high recurrence rate， and poor compliance. Although surgical treatment can cure cholecystitis， it is accompanied by the increased incidence of adverse events such as abdominal pain， diarrhea， and dyspepsia. Modern clinical studies have confirmed that Chaihu Guizhi Ganjiangtang can significantly alleviate the symptoms such as abdominal pain and dyspepsia of CC patients. Pharmacological studies have found that Chaihu Guizhi Ganjiangtang mainly contains active ingredients such as Bupleuri Radix saponins， baicalin， cinnamaldehyde， gingerol， Trichosanthis Radix polysaccharide， Ostreae Concha polysaccharide， and Glycyrrhizae Radix et Rhizoma total flavonoids. Chaihu Guizhi Ganjiangtang can ameliorate the symptoms of dyspepsia caused by CC by inhibiting inflammatory responses， improving gallbladder contraction and gastrointestinal motility， regulating the bile acid-intestinal flora axis and the brain-gut axis， and modulating blood lipids through multiple targets. By reviewing the previous literature， this article summarizes the research progress in the treatment of dyspepsia caused by CC with Chaihu Guizhi Ganjiangtang and its main active ingredients as well as the pathogenesis of this disease and puts forward the shortcomings and improvement strategies for the current research. The review aims to provide a reference for the further research on Chaihu Guizhi Ganjiangtang in the treatment of dyspepsia caused by CC.

Wastewater-based epidemiology has emerged as a transformative surveillance tool for estimating substance consumption and monitoring disease prevalence, particularly during the COVID-19 pandemic. It enables the population-level monitoring of illicit drug use, pathogen prevalence, and environmental pollutant exposure. In this perspective, we summarize the key challenges specific to the Chinese context: (1) Sampling inconsistencies, necessitating standardized 24-hour composite protocols with high-frequency autosamplers (≤ 15 min/event) to improve the representativeness of samples; (2) Biomarker validation, requiring rigorous assessment of excretion profiles and in-sewer stability; (3) Analytical method disparities, demanding inter-laboratory proficiency testing and the development of automated pretreatment instruments; (4) Catchment population dynamics, reducing estimation uncertainties through mobile phone data, flow-based models, or hydrochemical parameters; and (5) Ethical and data management concerns, including privacy risks for small communities, mitigated through data de-identification and tiered reporting platforms. To address these challenges, we propose an integrated framework that features adaptive sampling networks, multi-scale wastewater sample banks, biomarker databases with multidimensional metadata, and intelligent data dashboards. In summary, wastewater-based epidemiology offers unparalleled scalability for equitable health surveillance and can improve the health of the entire population by providing timely and objective information to guide the development of targeted policies.

Both carcinoembryonic antigen and CA19-9 are considered as predictive markers of intestinal cancer recurrence and metastasis.In addition,CA19-9 elevation is considered as a predictive marker of connective tissue disease-related interstitial lung disease.The incidence of oxaliplatin and capecitabine-associated interstitial lung disease is low,and there is no report about CA19-9 as a predictive marker of oxaliplatin and capecitabine-associated interstitial lung disease.This paper reports a case of interstitial lung disease with CA19-9 elevation caused by oxaliplatin and capecitabine adjuvant therapy for ileocecal carcinoma.The change trend of serum carcinoembryonic antigen in this patient was consistent with tumor recurrence and metastasis,and that of serum CA19-9 was consistent with the severity of interstitial lung disease.Therefore,CA19-9 elevation after intestinal cancer surgery does not necessarily indicate the tumor recurrence and metastasis,and attention should be paid to the possibility of oxaliplatin and capecitabine-associated interstitial lung disease.

Objective To observe brain structural changes in preterm infants and to analyze associated clinical risk factors based on 3D T1 structural MRI.Methods Brain 3D T1 structural MRI data of 82 preterm infants(preterm group)and 50 term infants(term group)were analyzed.Cortical morphology,including cortical thickness,surface area,sulcal depth and gyrification index were compared between groups.Spearman partial correlation analysis was used to explore the correlations of cortical structural changes and perinatal clinical variables.Results Compared with those in term group,increased cortical thickness of the right caudal middle frontal gyrus,reduced surface area of the left inferior parietal lobule,left precuneus and bilateral supramarginal gyrus,as well as decreased gyrification index in the right superior temporal gyrus,right lateral occipital gyrus,left inferior parietal lobule and left parahippocampal gyrus were observed in preterm group(all FDR corrected P＜0.05).No significant difference of sulcal depth was found between groups(all P＞0.05).Cortical surface area in bilateral supramarginal gyrus of preterm infant lowly-weakly negatively(rs=-0.327,-0.267,both P＜0.05)correlated,while the gyrification index in left parahippocampal gyrus of preterm infant weakly and positively(rs=0.221,P=0.045)correlated with maternal gestational diabetes mellitus.The surface area of left inferior parietal lobule,left precuneus,left supramarginal gyrus and right supramarginal gyrus in preterm infant weakly and negatively correlated with maternal infection during pregnancy(rs=-0.284—-0.224,all P＜0.05).Meanwhile,cortical thickness of the right caudal middle frontal gyrus and surface area of the right supramarginal gyrus in preterm infant lowly and negatively correlated with premature rupture of membranes(rs=-0.311,-0.301,both P＜0.05).Conclusion 3D T1 structural MRI was useful for detecting abnormal cortical morphology of preterm infants.Maternal gestational diabetes,infection during pregnancy and premature rupture of membranes might be risk factors for abnormal brain structure in newborns.

Objective:To evaluate the efficacy and safety of Nimotuzumab combined with concurrent chemoradiotherapy in elderly women with locally advanced cervical cancer.Methods:A retrospective analysis was conducted among elderly patients with cervical cancer who received nimotuzumab combined with concurrent chemoradiotherapy in the gynecology department of Beijing Hospital from November 2018 to March 2023.Efficacy assessments included the objective response rate(ORR), recurrence rates after 1-3 years of follow-up, and comparisons of the levels of squamous cell carcinoma antigen(SCC), carcino-embryonic antigen(CEA), and carbohydrate antigen 125(CA125)before and after treatment.Adverse reactions were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events(NCI-CTCAE)version 5.0.Results:A total of 47 elderly patients aged 60 years and older with stage ⅠB3-Ⅳa cervical cancer were included, with ages ranging from 60 to 76 years[mean age: (65.8±4.3) years; median age: 65(62, 70) years].The patients were divided into three age groups: 60-64 years(21 cases), 65-69 years(14 cases), and ≥70 years(12 cases).After treatment, SCC and CEA levels significantly decreased compared to pre-treatment levels, with statistically significant differences ( W=5.281 and 2.607, respectively; both P<0.05).However, there was no significant difference in CA125 levels before and after treatment( W=1.591, P=0.112).Among the 47 patients, 3 did not undergo post-treatment imaging examinations.Efficacy evaluation results were collected from 44 patients, including 21 cases of complete response(CR)(47.7%), 21 cases of partial response(PR)(47.7%), 1 case of stable disease(SD)(2.3%), and 1 case of progressive disease(PD)(2.3%).The ORR was 95.5%(42/44), and the diseae control rate was 97.7%(43/44).There were statistically significant differences in efficacy among different age groups(Fisher's exact test P=0.015).During the treatment process, a total of 36 patients experienced grade 3 or higher adverse reactions during treatment.Among them, 14 cases(29.8%)with grade 3 or higher acute hematological adverse reactions, 11 cases(23.4%)with grade 3 or higher acute gastrointestinal reactions, and 6 cases(12.8%)with grade 3 or higher acute urinary symptoms.Additionally, 2 cases of radiation cystitis and 3 cases of radiation proctitis were reported.There was no statistically significant difference in recurrence rates among different age groups(Fisher's exact test P=0.292).The highest recurrence rate among elderly patients was observed at the 2-3 year follow-up. Conclusions:For elderly patients with good organ function status, standard concurrent chemoradiotherapy combined with nimotuzumab may be an effective treatment for locally advanced cervical cancer.

AIM To explore the clinical effects of Supplemented Buyang Huanwu Decoction on postoperative patients with lumbar vertebral fracture complicated with spinal cord injury due to Qi Deficiency and Blood Stasis Pattern.METHODS One hundred and twenty patients were randomly assigned into control group(60 cases)for 6-week intervention of conventional treatment,and observation group(60 cases)for 6-week intervention of both Supplemented Buyang Huanwu Decoction and conventional treatment.The changes in clinical effects,TCM syndrome scores,spinal cord conduction signals(SEP amplitude,MEP amplitude),serum neurotrophic factors(NGF,IGF-1,BDNF),coagulation and inflammatory indices(PT,APTT,TNF-α,IL-1 β)and incidence of adverse reactions were detected.RESULTS The observation group demonstrated higher total effective rate than the control group(P＜0.05).After the treatment,the two groups displayed decreased TCM syndrome scores,TNF-α,IL-1β(P＜0.05),increased spinal cord conduction signals,coagulation and inflammatory indices(P＜0.05),and shortened PT,APTT(P＜0.05),especially for the observation group(P＜0.05).No significant difference in incidence of adverse reactions was found between the two groups(P＞0.05).CONCLUSION For the patients with lumbar vertebral fracture complicated with spinal cord injury due to Qi Deficiency and Blood Stasis Pattern,Supplemented Buyang Huanwu Decoction can safely and effectively promote neurological function recovery.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To explore the effect and mechanism of USP7 on immune and inflammatory response of EV71 infection.Methods:THP-1 cells were induced to differentiate into t-Mφ cells by PMA,cells were treated by targeted USP7 inhibitor P22077,and divided into DMSO control group and P22077 experimental group,and infected with EV71.ELISA was used to detect supernatant concentration of IL-6,CCL3,TNF-α of cells separately.RT-qPCR was used to detect RNA expression of EV71-VP1,plaque test was used to detect virus titer in cell supernatant.Western blot was used to detect expressions and phosphorylation of molecules related to innate immune signaling pathway.Full-length plasmid Myc-USP7 and Flag-MDA5 were constructed and transfected into HEK293T cells,and Co-IP was used to detect external interaction between USP7 and MDA5 with Myc antibody and Flag antibody,respectively.Infected t-Mφ cells with EV71,and Co-IP detection of their interaction by USP7 and MDA5 antibodies,respectively.t-Mφ cells of DMSO control group and P22077 experimental group were infected with EV71,CHX test was used to detect expression of MDA5 and downstream related molecules.Transfected Flag-MDA5,Myc-USP7,HA-Ub or HA-K48 plasmids,Co-IP detection of ubiquitination and ubiquitination types of MDA5 regulated by USP7 with Flag antibody.Co-IP detection of MDA5 ubiquitination types regulated by USP7 in t-Mφ cells by using MDA5 antibodies.Results:After infected with EV71 and inhibited of USP7,mRNA and protein expres-sions of IL-6,CCL3 and TNF-α were decreased(P<0.05),while EV71 replication(P<0.05),and titer increased;expression of MDA5,and activation of p-IKKα/β,p-IκBα and p-p65 in innate immunity signal pathway decreased.Interaction between USP7 and MDA5 could inhibit MDA5 degradation by inhibiting K48 ubiquitination of MDA5.Conclusion:USP7 stabilizes MDA5 expression by inhibiting K48 ubiquitination of MDA5,thereby positively regulating EV71 infection immunity and inflammatory response.

Objective:To investigate clinical characteristics, treatment approaches, and prognosis of drug-induced hypersensitivity syndrome (DIHS) in children.Methods:A retrospective analysis was performed on clinical data from pediatric inpatients with DIHS in Department of Dermatology, Beijing Children's Hospital from 2009 to 2023. The clinical data included demographic characteristics, clinical manifestations, laboratory findings, treatment regimens, and outcomes.Results:A total of 103 children with DIHS were included, comprising 54 males (52.4%) and 49 females (47.6%), with ages ( M [ Q1, Q3]) of 2.3 (1.2, 4.5) years.
