Objective To compare the long-term survival outcomes of patients with T_1-2N₀M₀ duodenal neuroendocrine tumor (DNET) after endoscopic resection (ER) or surgical resection (SR). Methods Patients diagnosed with T_1-2N₀M₀ DNET between January 1, 2004, and December 31, 2015, were extracted from the SEER database. Kaplan-Meier survival curve and log-rank test were used to compare overall survival (OS) rate and cancer-specific survival (CSS) rate between patients undergoing ER or SR. Propensity score matching (PSM) was used to reduce grouping differences, and multivariate Cox regression was used to analyze factors affecting OS and CSS before and after PSM. Results A total of 656 patients were included, with 457 in ER group and 199 in SR group. Before PSM, there was no significant difference in the 5-year OS rate between the ER and SR groups (88.9% vs 89.6%), but there was a significant difference in the 5-year CSS rate (99.3% vs 96.9%, P＝0.017). Before PSM, multivariate Cox regression analysis showed advanced age was an independent risk factor for decreased OS (P＜0.001). After PSM, there was no significant difference between the ER group (n＝187) and SR group (n＝187) in 5-year OS rate (90.2% vs 88.9%) or CSS rate (98.9% vs 96.7%). After PSM, multivariate Cox regression also showed advanced age was an independent risk factor for decreased OS, while resection method was not an independent factor for OS or CSS. Conclusions There is no significant difference in OS or CSS after endoscopic treatment and surgical treatments for patients with T_1-2N₀M₀ DNET, and advanced age is an independent factor for OS.

Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

AIM To explore the clinical effects of Shuilu Erxian Pills combined with Modified Didang Decoction on patients with early and middle stage diabetic nephropathy.METHODS Eighty-three patients were randomly assigned into control group(42 cases)for 12-week administration of Irbesartan Tablets,and observation group(41 cases)for 12-week administration of Shuilu Erxian Pills,Modified Didang Decoction and Irbesartan Tablets.The changes in clinical effects,TCM syndrome scores,blood glucose indices(FBG,HbA1c),blood lipid indices(TC,TG),renal function indices(BUN,Scr,24 h UTP,eGFR),inflammatory factors(IL-1β,hs-CRP,IL-6,TNF-α,IL-18,TGF-β1),immune function indices(lymphocyte,neutrophil,CD8+,CD3+,CD4+,CD4+/CD8+)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 observation group displayed decreased TCM syndrome scores,blood glucose indices,blood lipid indices,BUN,Scr,24 h UTP,inflammatory factors,CD8+(P＜0.05),reduced lymphocyte,neutrophil(P＜0.05),and increased eGFR,CD3+,CD4+,CD4+/CD8+(P＜0.05),which were more obvious than those in the control group(except for HbA1c,TG,SCr,24 h UTP,lymphocyte,neutrophil)(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 early and middle stage diabetic nephropathy,Shuilu Erxian Pills combined with Modified Didang Decoction can safely and effectively improve clinical symptoms,whose mechanism may contribute to the reduction of inflammatory levels and improvement of immune functions.

AIM To investigate the ameliorative effects of Schisandrol A(Sol A)in Suhuang antitussive capsule on post-infectious cough(PIC).METHODS The in vivo mouse PIC model was established by intratracheal instillation of lipopolysaccharide(LPS)combined with cigarette smoke exposure.The mice were randomly divided into the control group,the model group,the Suhuang antitussive capsule group(14 g/kg),the montelukast sodium positive control group(3 mg/kg),and low and high dose Sol A groups(10,30 mg/kg).The in vitro PIC model was established by stimulating human bronchial epithelial cells(BEAS-2B)with LPS.The cells were divided into the control group,the model group,the Suhuang antitussive capsule group(10 μg/mL)and low and high dose Sol A groups(3,10 μmol/L).HE and Masson staining were used to detect the pathological changes of the lung and bronchial tissues.ELISA was used to detect the levels of IL-1β,IL-6,TNF-α,ROS,MDA,SOD and GSH in the lung tissues.RT-qPCR was used to detect the IL-1β,IL-6 and TNF-α mRNA expressions in BEAS-2B cells.And Western blot was applied to detect the protein expressions of p-PI3K,p-Akt,NOX4,SIRT1,p-ERK,Fibronectin,E-cadherin,Vimentin and α-SMA in mouse lung tissue and BEAS-2B cells.RESULTS Compared with the model group,the groups intervened with Sol A or Suhuang antitussive capsule displayed prolonged cough latency(P＜0.01);reduced cough frequency(P＜0.01);relieved pulmonary inflammatory cell infiltration and collagen deposition in PIC mice;decreased pulmonary levels of IL-1β,IL-6,TNF-α,ROS,MDA and protein expressions of Fibronectin,Vimentin,α-SMA,p-ERK,p-PI3K,p-Akt,and NOX4(P＜0.05,P＜0.01);increased pulmonary levels of SOD and GSH and protein expressions of E-cadherin and SIRT1(P＜0.05,P＜0.01);decreased ROS level,IL-1β,IL-6,TNF-α mRNA expressions and p-ERK,p-PI3K,p-Akt,NOX4 protein expressions in vitro(P＜0.05,P＜0.01);and increased SIRT1 protein expression in vitro as well(P＜0.01).CONCLUSION Being the main antitussive component of Suhuang antitussive capsule upon the PIC model,Sol A inhibits the inflammation via SIRT1/ERK signaling pathway and relieve the oxidative stress via PI3K/Akt/NOX4 signaling pathway.

AIM To explore the effects of praeruptorin A from Suhuang antitussive capsules on cough variant asthma(CVA).METHODS The rats were randomly divided into the normal group,the model group,the dexamethasone group(0.5 mg/kg),the Suhuang antitussive capsules group(7 g/kg)and the low,medium and high dose praeruptorin A groups(15,30 and 60 mg/kg).The rat model of CVA was established by intraperitoneal injection of sensitizer(1 mg/mL ovalbumin and 10 mg/mL aluminum hydroxide)and aerosol inhalation of 1%ovalbumin followed by the corresponding dosing of drugs by gavage initiated on the 14th day.Another 14 days later,the rats had their pathological pulmonary changes observed by HE,Masson and PAS stainings;their number of inflammatory cells in bronchoalveolar lavage fluid(BALF)detected by hematology analyzer;and their levels of IL-4,IL-5,IL-13 and MUC5AC in BALF detected by ELISA.The RAW264.7 cell inflammatory model induced by lipopolysaccharide(LPS)was treated with 4,8,16 μmol/L praeruptorin A or 0.25 mg/mL Suhuang antitussive capsules,respectively.And the cells had their NO level detected by Griess method,and their ROS expression observed using fluorescence microscopy.The detections of the pulmonary and cellular mRNA expressions of IL-6,IL-1β,COX-2,iNOS and PPAR-γ by RT-qPCR;and the protein expressions of p-P65,P65,p-IκBα,IκBα,NLRP3,caspase-1(p20)and IL-1β by Western blot were conducted in both the cells and the rats.RESULTS The in vivo result showed that praeruptorin A reduced the cough frequency(P＜0.01);prolonged the cough latency(P＜0.05,P＜0.01);reduced the number of eosinophils and neutrophils in BALF(P＜0.05,P＜0.01);decreased the levels of IL-4,IL-5,IL-13 and MUC5AC in BALF and the pulmonary mRNA expressions of IL-6,IL-1β,COX-2 and iNOS(P＜0.05,P＜0.01);and decreased the phosphorylation of P65 and IκBα protein and NLRP3,caspase-1(p20)and IL-1β protein expressions(P＜0.05,P＜0.01)as well.The in vitro result showed that praeruptorin A inhibited the release of LPS-induced NO and reduce the ROS level(P＜0.01);decreased the mRNA expressions of IL-1β,COX-2 and iNOS(P＜0.05,P＜0.01);increased PPAR-γ mRNA expression(P＜0.05),and decreased the phosphorylation of P65 and IκBα protein and the expression of NLRP3 protein(P＜0.05,P＜0.01).CONCLUSION Praeruptorin A,one of the main antitussive components of Suhuang antitussive capsules,may improve CVA because of its anti-inflammatory and antitussive role by inhibiting the activation of NF-κB signaling pathway and reducing the expression of NLRP3 inflammatory corpuscles.

Objective To investigate the clinical characteristics and prognosis of pneumococcal meningitis(PM),and drug sensitivity of Streptococcus pneumoniae(SP)isolates in Chinese children.Methods A retrospective analysis was conducted on clinical information,laboratory data,and microbiological data of 160 hospitalized children under 15 years old with PM from January 2019 to December 2020 in 33 tertiary hospitals across the country.Results Among the 160 children with PM,there were 103 males and 57 females.The age ranged from 15 days to 15 years,with 109 cases(68.1% )aged 3 months to under 3 years.SP strains were isolated from 95 cases(59.4% )in cerebrospinal fluid cultures and from 57 cases(35.6% )in blood cultures.The positive rates of SP detection by cerebrospinal fluid metagenomic next-generation sequencing and cerebrospinal fluid SP antigen testing were 40% (35/87)and 27% (21/78),respectively.Fifty-five cases(34.4% )had one or more risk factors for purulent meningitis,113 cases(70.6% )had one or more extra-cranial infectious foci,and 18 cases(11.3% )had underlying diseases.The most common clinical symptoms were fever(147 cases,91.9% ),followed by lethargy(98 cases,61.3% )and vomiting(61 cases,38.1% ).Sixty-nine cases(43.1% )experienced intracranial complications during hospitalization,with subdural effusion and/or empyema being the most common complication[43 cases(26.9% )],followed by hydrocephalus in 24 cases(15.0% ),brain abscess in 23 cases(14.4% ),and cerebral hemorrhage in 8 cases(5.0% ).Subdural effusion and/or empyema and hydrocephalus mainly occurred in children under 1 year old,with rates of 91% (39/43)and 83% (20/24),respectively.SP strains exhibited complete sensitivity to vancomycin(100% ,75/75),linezolid(100% ,56/56),and meropenem(100% ,6/6).High sensitivity rates were also observed for levofloxacin(81% ,22/27),moxifloxacin(82% ,14/17),rifampicin(96% ,25/26),and chloramphenicol(91% ,21/23).However,low sensitivity rates were found for penicillin(16% ,11/68)and clindamycin(6% ,1/17),and SP strains were completely resistant to erythromycin(100% ,31/31).The rates of discharge with cure and improvement were 22.5% (36/160)and 66.2% (106/160),respectively,while 18 cases(11.3% )had adverse outcomes.Conclusions Pediatric PM is more common in children aged 3 months to under 3 years.Intracranial complications are more frequently observed in children under 1 year old.Fever is the most common clinical manifestation of PM,and subdural effusion/emphysema and hydrocephalus are the most frequent complications.Non-culture detection methods for cerebrospinal fluid can improve pathogen detection rates.Adverse outcomes can be noted in more than 10% of PM cases.SP strains are high sensitivity to vancomycin,linezolid,meropenem,levofloxacin,moxifloxacin,rifampicin,and chloramphenicol.[Chinese Journal of Contemporary Pediatrics,2024,26(2):131-138]

Objective:To compare the efficacy of unilateral percutaneous kyphoplasty (PKP) and unilateral PKP combined with posterior medial branch block of the contralateral spinal nerve in the treatment of lumbar osteoporotic vertebral compression fracture (OVCF) in the elderly.Methods:A retrospective cohort study was conducted to analyze the clinical data of 161 aged patients with newly developed lumbar OVCF, admitted to Xi′an Central Hospital Affiliated to Xi′an Jiaotong University School of Medicine from January 2019 to January 2023, including 58 males and 103 females, aged 61-88 [(72.9±6.3)years]. All the patients were diagnosed with type II compression fracture based on acute symptomatic osteoporotic thoracolumbar fracture classification (ASOTLF). Seventy-eight patients underwent unilateral PKP (PKP group), while the other 83 patients underwent unilateral PKP combined with posterior medial branch block of the contralateral spinal nerve (PKP+contralateral block group). The operation time, intraoperative blood loss, and length of hospital stay were recorded. Beck index of the injured vertebra, Cobb angle of lumbar lordosis, Roland-Morris disability (RMD) score, visual analogue scale (VAS), and Oswestry disability index (ODI) were evaluated before operation, at 1 day, 1 week, 1 month, 3 months after operation, and at the last follow-up. The incidence of complications such as cement leakage was recorded as well.Results:All the patients were followed up for 6-8 months [(6.7±0.6)months]. There were no significant differences between the two groups in the operation time, intraoperative blood loss, or length of hospital stay ( P>0.05). The Beck index of the injured vertebra and Cobb angle of lumbar lordosis were not significantly different between the two groups before operation, at 1 day, 1 week, 1 month, 3 months after operation, and at the last follow-up ( P>0.05). The RMD score of the injured vertebra, VAS score, and ODI were not significantly different between the two groups before operation ( P>0.05). At 1 day, 1 week, 1 month, 3 months after operation, and at the last follow-up, the RMD scores in the PKP+contralateral block group were (11.23±1.05)points, (10.90±1.11)points, (10.10±1.06)points, (9.94±1.06)points, and (9.60±0.83)points respectively, which were all lower than (17.55±0.71)points, (15.78±0.86)points, (13.42±0.92)points, (10.67±0.78)points, and (9.78±0.72)points in the PKP group ( P<0.05 or 0.01); the VAS scores in the PKP+contralateral block group were (3.02±0.60)points, (2.96±0.55)points, (2.92±0.57)points, (2.88±0.61)points, and (2.70±0.51)points respectively, which were all lower than (3.60±0.57)points, (3.47±0.55)points, (3.32±0.46)points, (2.99±0.47)points, and (2.77±0.42)points in the PKP group ( P<0.05 or 0.01); the ODI values in the PKP+contralateral block group were 14.43±1.29, 14.54±1.24, 14.63±1.32, 14.37±1.31, and 13.42±1.45 respectively, which were all lower than 16.72±1.64, 16.09±1.49, 14.82±1.53, 14.74±1.46, and 13.69±1.75 in the PKP group ( P<0.05 or 0.01). The bone cement leakage rate was 12.0% (10/83) in the PKP+contralateral block group, similar to 11.5% (9/78) in the PKP group ( P>0.05). No other complications such as neurovascular injury, pulmonary embolism or adjacent vertebral fracture were found in either groups. Conclusion:In the treatment of lumbar OVCF in the elderly, unilateral PKP combined with posterior medial branch block of the contralateral spinal nerve is similar to unilateral PKP in terms of the operation time, intraoperative blood loss, length of hospital stay, effectiveness of reduction, and incidence of complications, but it can achieve better pain relief and more satisfactory functional recovery.

Three new compounds, including a naphthoquinone, a reduced naphthoquinone derivative naphthalenone, and a tricarboxylic acid, along with five known naphthalenone derivatives were isolated from ethyl acetate extract of rice fermentation products of the fungus Pleosporales sp. by multiple column chromatographic methods, including Sephadex LH-20 gel column chromatography, silica gel column chromatography, reversed-phase HPLC, and chiral chromatography. Their structures were elucidated by MS, NMR, and specific rotation spectroscopic analyses as well as ECD calculations. Three novel compounds were named as pleospathone A (1), pleospathone B (2), and pleosporalic acid A (3). Five known compounds were separately identified as (3S,4R)-3,4,8-trihydroxy-6-methyl-3,4-dihydronaphthalen-1(2H)-one (4), (4R)-3,4-dihydro-4,6,8-trihydroxy-1(2H)-naphthalenone (5), (-)-scytalone (6), (3S,4S)-3,4-dihydro-3,4,6,8-tetrahydroxy-1(2H)-naphthalenone (7), and cis-4-hydroxyscytalone (8). Compounds 4-8 were isolated from the Pleosporales fungi for the first time. Compound 1 shows inhibitory activities against human cervical carcinoma cell line HeLa and murine leukemia cell line P388 with the IC₅₀ values of 78.93 and 98.80 μmol·L^-1, respectively.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.
