Objective: To analyze the timeliness of antir-etroviral therapy (ART) and its influencing factors among newly reported HIV/AIDS cases in Wenzhou City, Zhejiang Province from 2016 to 2023, so as to provide a reference for improving the ART effect of HIV/AIDS cases. Methods: Newly reported HIV/AIDS cases in Wenzhou City from 2016 to 2023 were selected as the research subjects. Demographic information, the situation of the first CD4+ T lymphocyte (CD4 cell) test, baseline CD4 cell count, and ART situation were collected through the Chinese Disease Prevention and Control Information System. The timely rate of ART was analyzed, and the influencing factors for timely ART among HIV/AIDS cases were analyzed using a multivariable logistic regression model. Results: A total of 4 500 newly reported HIV/AIDS cases in Wenzhou City from 2016 to 2023 were included, among which 3 679 were males, accounting for 81.76%, and 821 were females, accounting for 18.24%. The median age was 46.24 (interquartile range, 26.23) years. Among these cases, 3 606 received timely ART, with a timely rate of 80.13%. The timely rate of ART increased from 57.54% in 2016 to 91.97% in 2023 (P<0.05). Multivariable logistic regression analysis showed that unmarried/divorced/widowed (OR=0.769, 95%CI: 0.641-0.922), detainees (OR=0.492, 95%CI: 0.269-0.900), untimely first CD4 cell test (OR=0.278, 95%CI: 0.234-0.330), baseline CD4 cell count ≥200 cells/µL (OR=0.709, 95%CI: 0.595-0.843) or undetected (OR=0.131, 95%CI: 0.080-0.213) were associated with a lower timeliness for ART among HIV/AIDS cases. Conclusion From 2016 to 2023, the timely rate of ART among newly reported HIV/AIDS cases in Wenzhou City showed an upward trend, which was mainly affected by marital status, case source, timeliness of the first CD4 cell test, and baseline CD4 cell count.

Heart failure(HF)is the end stage of almost all cardiovascular diseases,including coronary heart disease and structural heart disease.For end-stage HF,medications and cardiac assist devices have limited therapeutic effects,and heart transplantation is associated with donor shortage and immune rejection.Alginate hydrogel has the ability to mechanically support and induce cardiac tissue regeneration and repair.In March 2021,we conducted the world's first transcatheter endocardial alginate-hydrogel implantation in patients with end-stage heart failure,and explored the safety and feasibility of the treatment.Given that patients with heart failure who had undergone cardiac resynchronization therapy defibrillator(CRT-D)were excluded from previous studies,this paper is the first to report a case of transcatheter endocardial alginate-hydrogel implantation in a patient with heart failure who did not respond to CRT-D,with a significant reduction in the number of visits to the doctor and a significant improvement in the quality of life during the post-procedure follow-up,which may expand the indications for the use of this technology.

Objective To evaluate the efficacy of extracorporeal membrane oxygenation(ECMO)in patients with reduced left ventricular ejection fraction(LVEF)undergoing transcatheter aortic valve implantation(TAVR).Methods This was a single-center,retrospective study enrolling a total of 30 patients with reduced LVEF undergoing TAVR from January 2020 to January 2024.Of these,12 patients underwent TAVR with ECMO.Baseline clinical characteristics,preprocedural echocardiographic and computed tomographic(CT)measurements,TAVR procedural details,and follow-up data at 60-day and 6-month were collected.Results Among the 30 patients,there were 20 males with an average age of(67.0±10.4)years,an average STS score of(8.2±1.8)points,and an average LVEF of(21.2±5.3)％.This study included 11 AR patients,all of whom were in the group without ECMO implantation,and the difference between the two groups was statistically significant(P=0.027).During the operation,there were 0 cases of circulatory collapse in the ECMO group,and 5 cases(5/18)of circulatory collapse in the non ECMO group.All 5 patients underwent emergency ECMO placement.There were statistically significant differences(P＜0.05)in the comparison of two groups with circulatory collapse and salvage ECMO implantation.The technical success rate of 30 patients was 76.7％(23/30),and the instrument success rate was 60.0％(18/30).Among them,the technical success rate and instrument success rate of the ECMO group were higher than those of the non ECMO group,but the differences were not statistically significant(both P＞0.05).During a 30 day follow-up,there were 0 all-cause deaths in the ECMO group and 9 all-cause deaths(9/18)in the non ECMO group.Among them,7 cases(7/18)died from cardiovascular causes.The differences in all-cause and cardiovascular cause deaths between the two groups were statistically significant(both P＜0.05).During a 6-month follow-up,one patient with ECMO died due to extensive cerebral infarction.The all-cause mortality rate during the 6-month follow-up was 1/12(8.3％),while the all-cause mortality rate without ECMO was 9/18(5.0％).The difference between the two groups was statistically significant(P=0.024).The incidence of stroke with ECMO was 1/12(8.3％),while without ECMO it was 0.There was no statistically significant difference between the two groups(P=0.978).Conclusions In patients with reduced LVEF undergoing TAVR,periprocedural ECMO support does seem to improve patient outcome.

Primary intestinal diffuse large B-cell lymphoma(PI-DLBCL)is clinically rare,but in recent years,with the gradual maturity of pathology and molecular biology technology,its incidence rate and diagnosis rate have also increased.Due to the lack of specificity of the clinical symptoms of PI-DLBCL,it is easy to misdiagnose and miss the diagnosis,and there is no consensus on the best treatment of PI-DLBCL in clinical practice.Therefore,by retrieving the latest literature at home and abroad,this review systematically discusses the pathogenesis,clinical manifestations,diagnostic criteria,treatment and prognosis of PI-DLBCL,in order to improve the understanding of rare PI-DLBCL in hematology and oncology,and provide reference for basic research and clinical diagnosis and treatment of PI-DLBCL.

Objective:To explore and analyze the clinical features and prognostic factors of secondary intestinal diffuse large B-cell lymphoma(SI-DLBCL),in order to provide reference for the basic research and clinical diagnosis and treatment of secondary lymphoma of rare sites in the field of hematology.Methods:The clinical data of 138 patients with SI-DLBCL admitted to Fujian Medical University Union Hospital from June 2011 to June 2022 were collected and sorted,the clinical and pathological features,diagnosis,treatment and prognosis were analyzed.Cox regression risk model was used to conduct univariate and multivariate analysis on the prognostic risk factors.Results:Among the 138 patients with SI-DLBCL included in this study,85(61.59％)were male,53(38.41％)were female,the median age of onset was 59.5(16-84)years,the clinical manifestations lacked specificity,the first-line treatment regimen was mainly chemotherapy(67.39％),94 cases(68.12％)received chemotherapy alone,40 cases(28.98％)were treated with chemotherapy combined with surgery,and 4 cases(2.90％)were treated with surgery alone.The median follow-up time was 72(1-148)months.Among the 138 patients with SI-DLBCL,79(57.25％)survived,34(24.64％)died,25 cases(18.12％)lost to follow-up,the PFS rates of 1-year,3-year and 5-year were 57.97％,49.28％and 32.61％,and the OS rates of 1-year,3-year and 5-year were 60.14％,54.35％and 34.06％,respectively.The results of univariate Cox regression analysis showed that age,Lugano stage and IPI score were the influencing factors of OS in SI-DLBCL patients,and age,Lugano stage and IPI score were the influencing factors of PFS in SI-DLBCL patients.The results of multivariate Cox analysis showed that Lugano stage was an independent prognostic factor affecting OS and PFS in SI-DLBCL patients.Conclusion:Patients with SI-DLBCL are more common in middle-aged and elderly men,and the early clinical manifestations lack specificity,and the first-line treatment regimen is mainly R-CHOP chemotherapy,and Lugano stage is an independent prognostic factor affecting OS and PFS in SI-DLBCL patients.

Objective:To summarize the clinical characteristics of patients with combined pneumocystis jiroveci pneumonia (PJP ) after allogeneic hematopoietic stem cell transplantation (allo-HSCT ). Methods:The clinical manifestations,laboratory tests,imaging findings,and treatment outcomes of 21 allo-HSCT patients with PJP diagnosed at the First Affiliated Hospital of Soochow University and Soochow Hopes Hematology Hospital from July 2018 to July 2023 were retrospective analyzed.Results:Among the 21 patients,the male-to-female ratio was 2.5:1,and the median age was 36 years old with a range of 15-62 years.The median time to diagnosis of PJP after transplantation was 225 days.The clinical manifestations lack specificity,and the main clinical symptoms include respiratory symptoms (dyspnea,cough,sputum,etc.) and fever.Laboratory examination revealed peripheral blood lymphocyte counts decreased in 15 cases,CD4+T lymphocyte absolute values less than 200 cells/μl in 19 patients,C-reactive protein levels significantly increased in 20 patients,lactate dehydrogenase levels increased in 14 patients,and 1,3-β-D-glucan detection levels increased in 14 patients.Chest CT manifestations can be divided into three types:ground glass type,nodular type,and mixed type.Among them,the incidence of ground glass type was the highest (18/21),with 2 cases of nodular type and 1 case of mixed type.The sequence number of Pneumocystis jiroveci was detected through mNGS (15-57570),and 11 patients had mixed infections.In terms of treatment,TMP-SMX,Caspofungin,and methylprednisolone were administered,and 17 patients achieved improvement in their condition.Four patients died,all of whom died from respiratory failure.Conclusion:PJP is a critically ill condition after hematopoietic stem cell transplantation,and diagnosis is difficult.Early diagnosis can achieve better prognosis.The sensitivity of mNGS in diagnosing PJP is high,providing the possibility of early and accurate diagnosis for clinical practice,which is worthy of application and promotion.

Objective:To evaluate the efficacy and safety of unilateral adrenalectomy for treating primary bilateral macronodular adrenal hyperplasia (PBMAH) of different clinical types.Methods:The clinical and biochemical data of 54 patients with PBMAH who underwent unilateral adrenalectomy from May 2008 to March 2023 were retrospectively collected. Preoperative CT images of all patients showed enlarged bilateral adrenal glands with multiple nodules of " fused masses". Mean preoperative blood cortisol concentration at 8am was (21.5±7.7)μg/dl, urinary free cortisol concentration was (442.6±300.4)μg/24h, and mean 8am ACTH concentration was (6.4±2.3)pg/ml. Postoperative symptoms, BMI, blood pressure, mass diameter, cortisol and ACTH concentration were recorded and analyzed.Results:Compared with ordinary laparoscopic surgery, robot-assisted surgery showed shorter operation time [(115.4±22.1)min vs.(95.0±19.8)min, P=0.045]; less blood loss [(118.2±57.0)ml vs. (125.6±45.3)ml, P=0.441] and shorter hospitalization time [(5.2±0.9)day vs. (6.4±1.2)day, P=0.279]. Compared with laparoscopic surgery, open surgery showed longer operation time [(134 34.5) min vs. (104.3±20.1) min, P=0.035]; more blood loss [(305.5±85.2) ml vs. (122.5±44.3) ml, P=0.012] and longer hospitalization time[(10.4±3.2)day vs. (5.7±1.0) day, P=0.020]. The average follow-up time was (23.7±11.7) months. Sixteen cases biochemically relapsed, and the average relapse-free time was (25.4±13.4) month. Mean postoperative systolic blood pressure was (131.1±16.8)mmHg ( P=0.001) while diastolic blood pressure decreased to (82.2±11.1)mmHg ( P=0.002). Postsurgical average blood cortisol concentration decreased to (10.2±4.0)μg/dl ( P<0.01), while urine cortisol concentration decreased to (106.6±43.4)μg/24h( P<0.01). Average ACTH concentration increased to (12.6±4.1)pg/ml( P=0.005). Recurrent patients had higher preoperative blood and urine cortisol concentration(24.7±8.2)μg/dl( P=0.046), (522.8±234.2)μg/24h( P=0.028), and all of them underwent contralateral adrenalectomy. Conclusions:Unilateral adrenalectomy is safe and effective for treatment of PBMAH while part of patients biochemically relapsed. Subclinical patients were observed no recurrent cases after surgery. Recurrent patients have higher preoperative blood and urine cortisol levels and should undertake contralateral adrenalectomy and supplement corticosteroids for whole life.

Objective:To evaluate the real-world safety of the domestic rotavirus attenuated live vaccine in China.Methods:Studies on the incidence of adverse event following immunization (AEFI) published from January 1, 2020 to July 31, 2023 were retrieved from National Knowledge Infrastructure (CNKI), CQVIP, Wanfang Database, PubMed, Medline, and Embase. Surveillance data about AEFI reports related to the domestic rotavirus vaccine rotavirus were collected. A meta-analysis on the safety of the rotavirus vaccine after vaccination was conducted using R software, and subgroup analyses were conducted on the incidence of AEFI in different regions and time periods.Results:A total of 36 articles were included involving 25.332 million doses of vaccine. The incidence of AEFI associated with the domestic rotavirus vaccine was 19/100 000 doses [95%CI: 15/100 000-24/100 000 doses]; the incidence was 26/100 000 doses [95%CI: 17/100 000-39/100 000 doses] in the northern regions and 16/100 000 doses [95%CI: 11/100 000-23/100 000 doses] in the southern regions; it was 24/100 000 doses [95%CI: 12/100 000-45/100 000 doses] before 2017 and 27/100 000 doses [95%CI: 18/100 000-39/100 000 doses] after 2017.Conclusions:The incidence of AEFI related to the domestic rotavirus vaccine is within the expected range, and the safety of the vaccine is good based on the real-world data.

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 construct an analytic method aimed at the characteristics of the commonly method of supplementing and pouring of acupuncture based on the analysis and modeling of ultrasound images around acupoint region in the process of acupuncture.Methods:A total of 7 healthy subjects who underwent physical examination in Beijing Zhongguancun Hospital from June,2022 to June,2023 were selected,and their Kongzui acupoints were acupunctured by 10 acupuncturists with associate senior title as 4 kinds of acupuncture manipulations included reinforcing by twisting and rotating(RFTR),reducing by twisting and rotating(RDTR),reinforcing by lifting and thrusting(RFLT),and reducing by lifting and thrusting(RDLT).The B-ultrasound diagnostic device was used to collect the images of muscle and fascial tissue below the acupoint,so as to construct the model of images.The definition of virtual acupuncture point was adopted to study the regulation of perturbation of subcutaneous tissue that was caused after the skin was acupunctured by needle.The change regulation of the virtual acupuncture point of muscle bundle below skin at Zuikong acupoint of subjects was analyzed.Results:The difference value of average absolution value between peak and trough of the trajectory of virtual acupuncture point of twisting and rotating was 0.066±0.045,and the average value of amplitude of this method was less than that(0.428±0.276)of lifting and thrusting method,and the twisting and rotating method was uniform and symmetrical,and there was difference between two kinds of acupuncture methods.The characteristics of computer graphics was used to qualify the work effect of lifting and thrusting,and reinforcing and reducing,which showed the heavy insertion and light lifting of RFLT,and showed heavy lifting and light insertion of RDLT,thus distinguished the two methods[(RFLT)and(RDLT)].Conclusions:The ultrasound imaging and computer graphics can be used to analyze the regularity of the common"reinforcing and reducing"method of acupuncture and moxibustion.
