The choice of biopsy method is critical in diagnosing prostate cancer (PCa). This retrospective cohort study compared systematic biopsy (SB) or cognitive fusion-targeted biopsy combined with SB (CB) in detecting PCa and clinically significant prostate cancer (csPCa). Data from 2572 men who underwent either SB or CB in Fudan University Shanghai Cancer Center (Shanghai, China) between January 2019 and December 2023 were analyzed. Propensity score matching (PSM) was used to balance baseline characteristics, and detection rates were compared before and after PSM. Subgroup analyses based on prostate-specific antigen (PSA) levels and Prostate Imaging-Reporting and Data System (PI-RADS) scores were performed. Primary and secondary outcomes were the detection rates of PCa and csPCa, respectively. Of 2572 men, 1778 were included in the PSM analysis. Before PSM, CB had higher detection rates for both PCa (62.9% vs 52.4%, odds ratio [OR]: 1.54, P < 0.001) and csPCa (54.9% vs 43.3%, OR: 1.60, P < 0.001) compared to SB. After PSM, CB remained superior in detecting PCa (63.1% vs 47.9%, OR: 1.86, P < 0.001) and csPCa (55.0% vs 38.2%, OR: 1.98, P < 0.001). In patients with PSA 4-12 ng ml -1 (>4 ng ml -1 and ≤12 ng ml -1 , which is also applicable to the following text), CB detected more PCa (59.8% vs 40.7%, OR: 2.17, P < 0.001) and csPCa (48.1% vs 27.7%, OR: 2.42, P < 0.001). CB also showed superior csPCa detection in those with PI-RADS 3 lesions (32.1% vs 18.0%, OR: 2.15, P = 0.038). Overall, CB significantly improves PCa and csPCa detection, especially in patients with PSA 4-12 ng ml -1 or PI-RADS 3 lesions.

OBJECTIVES: To investigate the clinical features of children with STAT gene mutations, and to explore corresponding immunotherapy strategies. METHODS: A retrospective analysis was performed for the clinical data of 10 children with STAT gene mutations who were admitted to the Department of Pediatrics of the First Affiliated Hospital of Guangzhou Medical University, from October 2015 to October 2024. Exploratory immunotherapy was implemented in some refractory cases, and the changes in symptoms, imaging manifestations, and cytokine levels were assessed after treatment. RESULTS: For the 10 children, the main clinical manifestations were recurrent rash since birth (7/10), cough (8/10), wheezing (5/10), expectoration (4/10), and purulent nasal discharge (4/10). Genotyping results showed that there was one child with heterozygous loss-of-function (LOF) mutation in the STAT1 gene, four children with heterozygous LOF mutation in the STAT3 gene, and five children with heterozygous gain-of-function (GOF) mutation in the STAT3 gene. Two children with LOF mutation in the STAT3 gene showed decreased interleukin-6 levels and improved clinical symptoms and imaging findings after omalizumab treatment. Three children with GOF mutation in the STAT3 gene achieved effective disease control after treatment with methylprednisolone (0.5 mg/kg per day). Two children with GOF mutation in the STAT3 gene received treatment with JAK inhibitor and then showed some improvement in symptoms. CONCLUSIONS STAT gene mutation screening should be considered for children with recurrent rash and purulent respiratory tract infections. Targeted immunotherapy may improve prognosis in patients with no response to conventional treatment.

Objective:To investigate the feasibility, safety and reasonable operation of nasointestinal canal indwelling guided by miniature system in severe neurosurgery patients, and compare its advantages and disadvantages with traditional blind insertion.Methods:A prospective randomized controlled trial design was used to select 128 critically ill patients in need of enteral nutrition support at the Department of Neurosurgery, the First Affiliated Hospital of Nanjing Medical University from March 2022 to October 2023 by convenient sampling method. They were divided into blind insertion group and visualization group by random number table method, with 64 cases in each group. Nasointestinal canal indwelling was performed in the blind insertion group by traditional blind insertion method, and in the visualization group, nasointestinal canal indwelling was performed by indentations guided by the miniature visualization system. The success rate of initial catheterization, the time of catheterization, complications, changes of vital signs during catheterization and changes of nutritional indexes after catheterization were evaluated in 2 groups.Results:In the blind insertion group, there were 35 males and 29 females, aged (59.44 ± 13.84) years old. In the visualization group, there were 41 males and 23 females, aged (58.28 ± 12.08) years old. The success rate of the first catheter placement in the visual group was 96.8% (62/64), higher than that in the blind group 82.8% (53/64), and the difference was statistically significant ( χ2=6.94, P<0.05). The catheter placement time of the visualization group was (20.08 ± 2.69) min, which was shorter than that of the blind insertion group (38.19 ± 3.79) min, and the difference between the two groups was statistically significant ( t=29.99, P<0.05). There was no significant difference in the incidence of complications, changes of vital signs during catheterization and the changes of nutritional indexes after catheterization between two groups (all P>0.05). Conclusions:Compared with traditional blind nasointestinal canal indwelling, nasointestinal canal indwelling guided by the miniature visualization system can improve the success rate of the first catheterization and shorten the catheterization time. Although there is no difference in the complication rate, changes in vital signs during catheterization and changes in nutritional indexes after catheterization, it is believed that with the continuous development and upgrading of this technology, it will further reflect the advantages of this technology, which is worthy of further clinical trials and application.

Objective:To investigate the correlation between nutritional status and quality of life in inpatients with nasopharyngeal carcinoma and to analyze the factors affecting nutritional status,so as to provide evidence for clinical nutritional support treatment.Methods:In this study,we retrospectively collected data from patients with nasopharyngeal carcinoma who met the inclusion and exclusion criteria in the Head and Neck Oncology Department of Zunyi Medical University Affiliated Hospital from 2014 to 2019.The NRS 2002 scale was used for nutritional risk screening,the PG-SGA scale for nutritional status assessment and the EORTCQLQ-C30 V3.0 scale for quality of life assessment.To further explore the correlation between nutritional status and quality of life,as well as the factors affecting nutritional status.Results:A total of 216 patients were collected,including 168 male(77.78%);average age(50.5±10.58)years;26.85%were at nutritional risk(NRS 2002 score≥3);28.70%were moderate malnutrition(PG-SGA score 4-8),and 23.15%were severe malnutrition(PG-SGA score≥9).There were significant differences in several physical examinations(such as body weight,body mass index,muscle circumference at the midpoint of the upper arm,etc.)and blood biochemical indexes(such as prealbumin,neutrophils,urea nitrogen,etc.)of patients with different nutritional status were differed between groups(P<0.05).Univariate analysis showed that age≥65 years was a risk factor for the development of severe malnutrition(OR:3.429,95%CI:1.467 to 8.014,P=0.004),whereas a high level of education(senior high school and above)was a protective factor(OR:0.027,95%CI:0.011 to 0.064,P=0.000).The poorer the nutritional status of nasopharyngeal carcinoma patients,the lower the quality of life.Conclusion:Nasopharyngeal carcinoma patients have a high incidence of malnutrition;the poorer the nutritional status of the patient,the lower the quality of life;routine nutritional diagnosis and treatment of nasopharyngeal carcinoma patients after admission to the hospital is recommended to improve clinical outcomes.

AIM To explore the clinical effects of Polygonum cuspidatum Sieb.et Zucc.on patients with type 2 diabetes mellitus of Dampness-Heat Pattern.METHODS One hundred and forty patients were randomly assigned into control group(70 cases)for 8-week intervention of conventional treatment,and observation group(70 cases)for 8-week intervention of both P.cuspidatum granules and conventional treatment.The changes in body weight,BMI,blood glucose indices(FBG,2 h PG,HbA1C,GA),blood lipid indices(TC,TG,HDL-C,LDL-C,ApoA-I,ApoB,ApoA,ApoE,sdLDL-C),liver function indices(ALT,AST),fatty liver progression,TyG,HSI,TCM syndrome score and effects were detected.RESULTS The observation group demonstrated higher total effective rates of TCM syndromes than the control group(P＜0.01),along with slighter fatty liver progression(P＜0.01).After the treatment,the observation group displayed decreased body weight,BMI,FBG,GA,TG,ApoE,TyG,HSI,ALT and TCM syndrome score(P＜0.05,P＜0.01),and 2 h PG,TyG,HSI,ALT,TCM syndrome score were lower than those in the control group(P＜0.05,P＜0.01).CONCLUSION For the patients with type 2 diabetes mellitus of Dampness-Heat Pattern,P.cuspidatum can improve glucose and lipid metabolism disorders,which is worthy of clinical popularization and application.

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 investigate the value of carvedilol or propranolol in preventing rebleeding in patients with esophageal variceal bleeding(EVB)in liver cirrhosis.Methods Patients with EVB in liver cirrhosis were divided into the treatment group and the control group.The treatment group was treated with oral administration of carvedilol dispersible tablets,with an initial dose of 6.25 mg,bid.The control group was treated with oral administration of propranolol hydrochloride tablets,with an initial dose of 20 mg,bid.The treatment course of two groups was 1 year.The effects between two groups were compared.The rebleeding rate,and hemodynamics between two groups were compared treated after 6 months and 1 year of treatment.Safety that occurred during treatment were observed.Results The treatment group consisted of 64 patients,while the control group consisted of 61 patients.After treatment,the overall response rate in the treatment group was 93.75％(60 cases/64 cases),while the control group was 91.80％(56 cases/61 cases),without statistically significant difference between the groups(all P＞0.05).After 6 months of treatment,rebleeding rates in the treatment group and the control group were 4.69％(3 cases/64 cases)and 9.84％(6 cases/61 cases),without statistically significant difference between the groups(P＞0.05).After 1 year of treatment,rebleeding rates in the treatment group and the control group were 10.94％(7 cases/64 cases)and 24.59％(15 cases/61 cases),without statistically significant difference between the groups(P＜0.05).After 6 months of treatment,portal vein diameter(PVD)in the treatment group and the control group were(12.39±2.41)and(13.88±1.76)mm;splenic vein diameter(SVD)were(7.56±1.52)and(8.35±1.69)mm;mean blood flow velocity of portal vein(Vp)were(35.26±7.04)and(38.12±7.60)cm·s-1;mean blood flow velocity of splenic vein(Vs)were(20.03±4.11)and(22.34±4.69)cm·s-1.Compared with control group,the above indexes of treatment group had statistical significance(all P＜0.05).After 1 year of treatment,PVD in the treatment group and the control group were(11.87±2.52)and(13.15±2.04)mm;SVD were(7.33±1.48)and(8.22±1.55)mm;Vp were(33.96±6.75)and(37.46±6.83)cm·s-1;Vs were(19.26±4.33)and(21.55±4.47)cm·s-1.Compared with control group,the above indexes of treatment group had statistical significance(all P＜0.05).Adverse drug reactions in the treatment group included bradycardia,hypotension,dizziness,nausea and vomiting,while adverse reactions in the control group included bradycardia,hypotension,dizziness,drowsiness,nausea and vomiting,and skin rash.The total incidence of adverse drug reactions in the treatment group was 12.50％,while the control group was 27.87％,the differences were statistically significant(P＜0.05).Conclusion Compared to propranolol,carvedilol can better prevent rebleeding and relieve esophageal varices.

This study was aimed at understanding the detection rate,drug resistance characteristics,virulence characteris-tics,multi-locus sequence typing,and other molecular epidemic and pathogenic characteristics of Campylobacter jejuni and Campylobacter coli in children in Guangdong Province from 2020 to 2022.Anal swabs or stool samples of suspected infection cases in children from 2020 to 2022 were collected from two hospitals in Guangzhou,Guangdong Province.Campylobacter was isolated and cultured through the filtration method,and identified with a microbial mass spectrometry system;antibiotic resist-ance was analyzed with the agar dilution method;bacterial genome nucleic acids were extracted,and whole-genome sequencing was conducted;and drug resistance genes,virulence genes,multi-locus sequence typing,and phylogenetic analysis based on whole-genome single nucleotide polymorphisms were analyzed from whole-genome sequencing results.First,53 strains of Campy-lobacter were detected through continuous routine monitoring in this study,with a positive detection rate of 2.94％.Among them,Campylobacter jejuni accounted for 81.13％(43/53)and Campylobacter coli accounted for 18.87％(10/53).In addition,16 strains of Campylobacter were screened through multi-pathogen surveillance,including 11 strains of Campylobacter jejuni and 5 strains of Campylobacter coli.Drug resistance ex-periments and whole genome sequencing were conducted on 46 Campylobacter isolates,including 33 isolates of Campylobacter jejuni and 13 isolates of Campylobacter coli.The resistance rate of Campylobacter to erythromycin,a widely used clinical treatment,was21.73％(10/46);that to tetracycline was 80.43％(37/46);those to the quinolone antibiotics nalidixic acid and ciprofloxacin were 76.08％(35/46)and 71.73％(33/46)respectively;and that to chloramphenicol was lowest,at 2.17％(1/46).The drug resistance rate was generally higher for Campylobacter coli than Campylobacter jejuni,and the differences in the indicators of erythromycin,gentamicin,streptomycin,telithromycin,and clindamycin were statistically significant.A total of 30 isolates of multidrug-resistant Campylobacter were detected,including nine multidrug-resistant phenotypes.Whole-ge-nome sequence analysis indicated that 46 Campylobacter isolates carried antibiotic resistance genes for antibiotics such as quino-lones,tetracyclines,β-lactams,and aminoglycosides,and carried 128 virulence factor genes in five categories.All 46 isolates of Campylobacter were identified as 35 ST type through MLST typing,and phylogenetic analysis indicated no obvious dominant ST type.Campylobacter coli had more SNPs than Campylobacter jejuni.In conclusion,the positive detection rate of Campy-lobacter in Guangzhou City,Guangdong Province stabilized from 2020 to 2022,and the detection rate of Campylobacter jejuni was higher than that of Campylobacter coli.Campylobacter isolates were resistant to tetracyclines and quinolone,and showed a wide spectrum of multi-drug resistance,which was relatively severe among Campylobacter coli.Resistance genes and drug-resistant phenotypes were correlated and had predictive significance.The virulence genes of Campylobacter jejuni were more a-bundant than those of Campylobacter coli,possibly because of the higher detection rate and pathogenicity of Campylobacter jejuni.The phylogenetic tree showed clear branches with high genetic diversity and no clearly dominant clonal group.

Objective To analyze the incidence and disease burden of substance use disorder(SUD)in China from 1990 to 2019,to evaluate the impact of different ages,periods and birth cohorts on the disease burden of SUD,and to predict disease burden of SUD from 2020 to 2034,so as to provide strategies for the prevention of SUD.Methods Based on the Global Burden of Disease Study 2019(GBD 2019)database,the disease burden was described by incidence,years of life lost(YLLs),years lived with disability(YLDs)and disability-adjusted life years(DALYs).The Joinpoint regression model was used to analyze the trend of standardized incidence and standardized DALYs rate of SUD.Based on the age-period-cohort model,the age,period and cohort effects of SUD were discussed.The grey prediction model GM(1,1)was used to fit the trend of the incidence and standardized incidence of SUD and the trend of disease burden,and to predict the incidence and disease burden of SUD in 2020-2034.Results From 1990 to 2019,the standardized incidence of SUD of amphetamines[average annual percentage change(AAPC)=-0.9％]and cocaine(AAPC=-0.5％)in China showed a downward trend(P＜0.001),and the standardized incidence of SUD of cannabis(AAPC=0.9％)showed an increasing trend year by year(P＜0.001).The trend of standardized incidence of opioid abuse disorders was not obvious(P＞0.05).The DALYs rate caused by the 4 SUD showed a decreasing trend year by year(AAPCamphetamines=-2.2％,AAPCcocaine=-1.5％,AAPCcannabis=-1.0％,AAPCopioids=-1.0％,P＜0.001).The results of age-period-cohort effect showed that the peak incidence of amphetamine,cocaine,cannabis and opioid use disorders was in the 25-30 age group.The DALYs rate caused by cannabis SUD increased with age,while the DALYs rates of amphetamines,cocaine and opioids SUD reached the peak in the 25-29,30-34 and 35-39 age groups,respectively.The results of period effect showed that the risk of SUD in propylamines,cocaine and cannabis decreased first and then increased,while the risk of SUD in opioids increased and then decreased and increased again.The results of birth cohort effect showed that the risk of SUD of amphetamines,cocaine and opioids showed a decreasing trend as a whole except for a small fluctuation in individual birth cohorts.The risk of DALYs rate caused by SUD of amphetamines,cocaine and opioids showed a decreasing trend as a whole,while the risk of DALYs rate caused by SUD of cannabis showed an increasing trend year by year.The prediction results showed that the incidence of SUD of amphetamines,cocaine and opioids showed a downward trend from 2020 to 2034,and the incidence of SUD of cannabis showed a fluctuating upward trend.The DALYs attributed to SUD of amphetamines,cocaine,cannabis and opioids showed a decreasing trend year by year.Conclusion The disease burden of SUD in China is decreasing year by year in the future.The incidence and disease burden are affected by age effect,period effect and cohort effect to varying degrees.Early prevention and effective intervention are the key measures to control SUD.

Colorectal cancer (CRC) is a prevalent malignant tumor often leading to liver metastasis and mortality. Despite some success with PD-1/PD-L1 immunotherapy, the response rate for colon cancer patients remains relatively low. This is closely related to the immunosuppressive tumor microenvironment mediated by tumor-associated macrophages (TAMs). Our previous work identified that a phosphoglycerate mutase 1 (PGAM1) allosteric inhibitor, HKB99, exerts a range of anti-tumor activities in lung cancer. Here, we found that upregulation of PGAM1 correlates with increased levels of M2-like tumor-associated macrophages (TAMs) in human colon cancer samples, particularly in liver metastatic tissues. HKB99 suppressed tumor growth and metastasis in cell culture and syngeneic tumor models. M2-polarization, induced by colon cancer cell co-culture, was reversed by HKB99. Conversely, the increased migration of colon cancer cells by M2-TAMs was remarkably restrained by HKB99. Notably, a decrease in TAM infiltration was required for the HKB99-mediated anti-tumor effect, along with an increase in CD8⁺ T cell infiltration. Moreover, HKB99 improved the efficacy of anti-PD-1 treatment in syngeneic tumors. Overall, this study highlights HKB99's inhibitory activity in TAM-mediated colon cancer progression. Targeting PGAM1 could lead to novel therapeutic strategies and enhance the effectiveness of existing immunotherapies for colon cancer.
