Objective To explore the effects of standardized environmental enrichment(EE)on cognitive function and serum brain-derived neurotrophic factor(BDNF)levels in patients with post-stroke dementia.Methods A prospective study was conducted,including 80 patients with post-stroke dementia admitted to Department of Traditional Chinese Medicine Rehabilitation,910th Hospital of the Joint Logistics Support Force of Chinese PLA from January 2021 to May 2023.Patients were randomly divided into control group,cognitive training(COG)group,aerobic exercise training(AE)group and environmental enrichment(EE)group,with 20 cases in each group.All patients received routine treatment,with COG group receiving additional cognitive function training(30 minutes each time),AE group receiving additional aerobic exercise training(30 minutes each time),and EE group receiving both aerobic exercise and cognitive function training(15 minutes of aerobic exercise training and 15 minutes of cognitive training each time).The training was conducted once a day,5 days a week,for a total of 8 weeks.The patients'mini-mental state scale(MMSE),modified Barthel index(MBI),Hamilton depression scale(HAMD),stroke-specific quality of life(SS-QOL)score and serum levels of BDNF were assessed before treatment,at 4 weeks and 8 weeks of treatment,respectively.Results Before treatment,there were no significant differences in general information,MMSE,MBI,HAMD,SS-QOL scores,and serum levels of BDNF among the four groups(P＞0.05).After 4 and 8 weeks of treatment,the above indicators of the four groups were improved compared with those before treatment,with all differences being statistically significant(P＜0.05).Inter-group comparison showed that after 4 and 8 weeks of treatment,MMSE,MBI,SS-QOL scores,and serum BDNF levels in COG,AE and EE groups were significantly higher than those in control group,and HAMD scores were significantly lower than those in control group(P＜0.05).In addition,MMSE,MBI,SS-QOL scores and BDNF levels of group EE were better than those of other 3 groups,while HAMD scores were lower than those of other 3 groups,with all differences being statistically significant(P＜0.05).There was no significant difference in above outcome indicators between COG group and AE group after 4 and 8 weeks of treatment(P＞0.05).Conclusion Standardized enrichment environment can significantly enhance cognitive function,daily living abilities of post-stroke dementia patients,alleviate depression symptoms,and improve the quality of life,which may be related to the increase in serum BDNF levels.

Objective: Retrospective analysis of the efficacy and influencing factors of bladder preservation integrated therapy for unresectable invasive bladder cancer confined to the pelvis was done, also including the bladder function preservation and adverse effects analysis. Methods: Sixty-nine patients with unresectable locally invasive bladder cancer who received radiotherapy-based combination therapy from March 1999 to December 2021 at our hospital were selected. Among them, 42 patients received concurrent chemoradiotherapy, 32 underwent neoadjuvant chemotherapyand 43 with transurethral resection of bladder tumors (TURBT) prior to radiotherapy. The late adverse effect of radiotherapy, preservation of bladder function, replase and metastasis and survival were followed-up. Cox proportional hazards models were applied for the multifactorial analysis. Results: The median age was 69 years. There were 63 cases (91.3%) of uroepithelial carcinoma, 64 of stage Ⅲ and 4 of stage Ⅳ. The median duration of follow-up was 76 months. There were 7 grade 2 late genito urinary toxicities, 2 grade 2 gastrointestinal toxicities, no grade 3 or higher adverse events occurred. All patients maintained normal bladder function, except for 8 cases who lost bladder function due to uncontrolled tumor in the bladder. Seventeen cases recurred locally. There were 11 cases in the concurrent chemoradiotherapy group with a local recurrence rate of 26.2% (11/42) and 6 cases in the non-concurrent chemoradiotherapy group with a local recurrence rate of 22.2% (6/27), and the difference in local recurrence rate between the two groups was not statistically significant (P=0.709). There were 23 cases of distant metastasis (including 2 cases of local recurrence with distant metastasis), including 10 cases in the concurrent chemoradiotherapy group with a distant metastasis rate of 23.8% (10/42) and 13 cases in the non-concurrent chemoradiotherapy group with a distant metastasis rate of 48.1% (13/27), and the distant metastasis rate in the non-concurrent chemoradiotherapy group was higher than that in the concurrent chemoradiotherapy group (P=0.036). The median 5-year overall survival (OS) time was 59 months and the OS rate was 47.8%. The 5-year progression-free survival (PFS) time was 20 months and the PFS rate was 34.4%. The 5-year OS rates of concurrent and non-concurrent chemoradiotherapy group were 62.9% and 27.6% (P<0.001), and 5-year PFS rates were 45.4% and 20.0%, respectively (P=0.022). The 5-year OS rates of with or without neoadjuvant chemotherapy were 78.4% and 30.1% (P=0.002), and the 5-year PFS rates were 49.1% and 25.1% (P=0.087), respectively. The 5-year OS rates with or without TURBT before radiotherapy were 45.5% and 51.9% (P=0.233) and the 5-year PFS rates were 30.8% and 39.9% (P=0.198), respectively. Multivariate Cox regression analysis results showed that the clinical stage (HR=0.422, 95% CI: 0.205-0.869) was independent prognostic factor for PFS of invasive bladder cancer. The multivariate analysis showed that clinical stages (HR=0.278, 95% CI: 0.114-0.678), concurrent chemoradiotherapy (HR=0.391, 95% CI: 0.165-0.930), neoadjuvant chemotherapy (HR=0.188, 95% CI: 0.058-0.611), and recurrences (HR=10.855, 95% CI: 3.655-32.638) were independent prognostic factors for OS of invasive bladder cancer. Conclusion: Unresectable localized invasive bladder cancer can achieve satisfactory long-term outcomes with bladder-preserving combination therapy based on radiotherapy, most patients can retain normal bladder function with acceptable late adverse effects and improved survival particularly evident in patients with early, concurrent chemoradiotherapy and neoadjuvant chemotherapy.

During 4-month multidisciplinary follow-up, no scars or complications of the eyes, mouth, genitalia, or lungs occurred.Conclusion:Systematic wound management is helpful to control the progress of SJS/TEN, accelerate wound healing, and improve patients′ quality of life.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Objective:To evaluate the clinical efficacy and safety of adalimumab combined with acitretin in the treatment of childhood generalized pustular psoriasis.Methods:Five children with generalized pustular psoriasis were collected from Department of Dermatology, Tianjin Children′s Hospital from October 2019 to August 2020. After admission, the patients received oral acitretin at a dose of 0.5 mg·kg -1·d -1. After relevant laboratory examinations, these patients additionally received subcutaneous injections of 20- or 40-mg adalimumab at weeks 0 (the initial dose) , 1, and every 2 weeks thereafter; when patients obtained a 50% improvement in the Japanese Dermatology Association (JDA) severity index score, the dose of acitretin would be reduced to 0.3 mg·kg -1·d -1, and acitretin would be discontinued after a 75% improvement. The disease condition was evaluated at weeks 0, 1, 2, 4, 8, 12 and 24 after the start of adalimumab treatment, and adverse reactions were monitored during treatment. Results:All the 5 patients received drug treatment for at least 40 weeks. After 2-week treatment, 3 patients achieved a 50% reduction in JDA severity index score (JDA50) ; after 4-week treatment, 4 achieved JDA75, and 1 achieved JDA100; after 8-week treatment, all the 5 patients achieved JDA100. By June 2021, all the 5 children received follow-up for at least 40 weeks, no recurrence was observed during the treatment period, and no infections, malignant tumors or other serious adverse reactions occurred.Conclusion:Adalimumab combined with acitretin shows rapid onset of action and high safety in the treatment of childhood generalized pustular psoriasis.

Objective: To explore the safety and effectiveness of stereotactic body radiation therapy (SBRT) for oligometastases from colorectal cancer (CRC). Methods: This is a prospective, single-arm phase Ⅱ trial. Patients who had histologically proven CRC, 1 to 5 detectable liver or lung metastatic lesions with maximum diameter of any metastases ≤5 cm were eligible. SBRT was delivered to all lesions. The primary endpoint was 3-year local control (LC). The secondary endpoints were treatment-related acute toxicities of grade 3 and above, 1-year and 3-year overall survival (OS) and progression free survival (PFS). Survival analysis was performed using the Kaplan-Meier method and Log rank test. Results: Petients from 2016 to 2019 who were treated in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. Forty-eight patients with 60 lesions were enrolled, including 37 liver lesions and 23 lung lesions. Forty-six patients had 1 or 2 lesions, with median diameter of 1.3 cm, the median biologically effective dose (BED(10)) was 100.0 Gy. The median follow-up was 19.5 months for all lesions. Twenty-five lesions developed local failure, the median local progression free survival was 15 months. The 1-year LC, OS and PFS was 70.2% (95% CI, 63.7%~76.7%), 89.0% (95% CI, 84.3%~93.7%) and 40.4% (95%CI, 33.0%~47.8%). The univariate analysis revealed that planning target volume (PTV) and total dose were independent prognostic factors of LC (P<0.05). For liver and lung lesions, the 1-year LC, OS and PFS was 58.7% and 89.4% (P=0.015), 89.3% and 86.5% (P=0.732), 30.5% and 65.6% (P=0.024), respectively. No patients developed acute toxicity of grade 3 and above. Conclusion: SBRT is safe and effective treatment method for oligometastases from CRC under precise respiratory motion management and robust quality assurance.

Background:The role of local treatment in oligometastatic prostate cancer (PCa) is gaining interest with the oligometastases hypothesis proposed and the improvement of various surgical methods and techniques.This study aimed to compare the short-term therapeutic outcomes of robotic-assisted laparoscopic radical prostatectomy (RALP) for oligometastatic prostate cancer (OPC) vs.localized PCa using propensity score matching.Methods:Totally 508 consecutive patients underwent RALP as a first-line treatment.The patients were divided into two groups according to oligometastatic state:the OPC group (n =41) or the localized PCa group (n =467).Oligometastatic disease was defined as the presence of two or fewer suspicious lesions.The association between the oligometastatic state and therapeutic outcomes of RALP was evaluated,including biochemical recurrence (BCR) and overall survival (OS).A Cox proportional hazards model was used to assess the possible risk factors for BCR.Results:Totally 41 pairs of patients were matched.The median operative time,the median blood loss,the overall positive surgical margin rate,the median post-operative hospital stays,and the post-operative urinary continence recovery rate between the two groups showed no statistical significance.The 4-year BCR survival rates of the OPC group and localized PCa group were 56.7％ and 60.8％,respectively,without a significant difference (P=0.804).The 5-year OS rates were 96.3％ and 100％,respectively (P =0.326).Additionally,the results of Cox regression showed that oligometastatic state was not an independent risk factor for BCR (P =0.682).Conclusions:Our findings supported the safety and effectiveness of RALP in OPC.Additionally,oligometastatic state and sites did not have an adverse effect on BCR independently.

Objective: To establish a rapid on-site method for identifying Chinese medical material recombinase-mediated amplification (RAA) technology for the use of identifying medicinal Bubali Cornu from yak horn. Method: Based on the differences of mitochondrial genome sequences between Bubali Cornu and adulterants,the specific RAA primer (SNJ-1.F,SNJ-1.R) and fluorescence probe SNJ-1.probe were designed by variation sites. Alkaline lysis method was used to extract DNA from milled samples,and optimize RAA reaction system. The incubation was made at 37℃ for 15-20 min, the reaction results were monitored through gel electrophoresis and a mobile fluorescence amplification instrument. The RAA identification result was compared with COI DNA sequencing. Result: After incubation at 37℃ for 20 min,about 140 bp of bright and simple bands was amplified from DNA templates of Bubalus bubalis,whereas Bos mutus were negative. By the Real-time fluorescent RAA identify method,all reactions in DNAs from Bubali Cornu samples were amplified from 6.21 to 8.37 min,whereas DNAs from yak samples were amplified after 10.08 min,COI sequencing results conformed to the Real-time fluorescent RAA identification. Conclusion: Specific RAA could rapidly identify Bubali Cornu in 20 minutes, and thus be applied in medical material and its products. This method is simple,rapid and sophisticated instrument-free,with promises in on-site identification of traditional Chinese medicine.
