Objective:To explore the effect of continuous nursing based on Siebens domain management model in patients with Parkinson's disease after deep brain stimulation.Methods:From January 2021 to June 2022, convenience sampling was used to select 169 Parkinson's disease patients who underwent deep brain electrical stimulation in the Functional Neurosurgery of Beijing Tiantan Hospital as the study subject. The patients were divided into a control group of 84 cases and an observation group of 85 cases using the random number table method. The control group received routine continuous nursing, while the observation group received the continuous nursing based on Siebens domain management model on the basis of the control group. This study compared the Activity of Daily Living (ADL) Scale, Morisky Medication Adherence Scale (MMAS), 39-item Parkinson Disease Questionnaire (PDQ-39), Parkinson's Disease Sleep Scale (PDSS) scores, and unexpected program control rate between two groups of patients after six months of discharge.Results:After six months of discharge, the ability of daily living score, quality of life score, and sleep quality score of both groups of patients improved compared to before intervention ( P<0.05), and the medication adherence of the observation group patients improved compared to before intervention ( P<0.05), and the differences were statistically significant. The ability of daily living score, medication adherence, quality of life score, and sleep quality score of the observation group patients after six months were higher than those of the control group, and the differences were statistically significant ( P<0.05). Within six months after discharge, the unexpected program control rate of the observation group was statistically lower than that of the control group ( P<0.05) . Conclusions:In the treatment and discharge rehabilitation process of Parkinson's patients treated with deep brain electrical stimulation, adopting continuous nursing based on the Siebens domain management model can help ensure patient medication compliance, improve postoperative sleep quality and quality of life, reduce unexpected program control frequency, and have certain clinical practice value.

OBJECTIVE To provide reference for safe drug use in the clinic by mining the adverse drug event （ADE） signals of 4 kinds of biological agents for the treatment of inflammatory bowel disease （IBD）. METHODS ADE data of infliximab， adalimumab， ustekinumab and vedolizumab were collected from the FDA adverse event reporting system between the first quarter in 2004 and the fourth quarter in 2022， and were mined by using reporting odds ratio （ROR） method and proportional reporting ratio （PRR） method. The system organ class （SOC） was used for the classification and statistics of drug ADE terminology. RESULTS & CONCLUSIONS A total of 65 173， 247 894， 37 596 and 6 134 ADE reports were retrieved for the above 4 biologic agents， involving 1 664， 1 731， 588， 303 ADE signals and 27， 27， 24， 26 SOC， respectively. The largest number of ADE reported of infliximab were various musculoskeletal and connective tissue diseases， and the signal intensity of disseminated tuberculosis was stronger. The largest number of ADE reported of adalimumab were systemic disease and various reactions at the administration site， and the signal intensity of papular at the injection site was stronger. The largest number of ADE reported of ustekinumab were various injuries， poisoning and operation complications， and the signal intensity of latent tuberculosis was slightly stronger. The largest number of ADE reported of vedolizumab were systemic diseases and various reactions at the administration site， and the signal intensity of shorter treatment response time was stronger. When clinically administering the four drugs， it is crucial to pay close attention to common ADEs and other ADE not mentioned in the drug label. For infliximab， clinicians should exercise caution due to the potential risk of synovitis and basal cell carcinoma； when prescribing adalimumab， caution should be exercised due to ADEs related to synovitis and hernia； for ustekinumab， the ADE associated with hepatobiliary diseases should be vigilant； for vedolizumab， clinicians should be vigilant for blood in the stool， increasing frequency of defecation. Except for ustekinumab， the other 3 biological agents also require attention for ADE associated with pregnancy.

Objective To compare the efficacy of mediastinoscope-assisted transhiatal esophagectomy (MATHE) and functional minimally invasive esophagectomy (FMIE) for esophageal cancer. Methods Patients who underwent minimally invasive esophagectomy at Jining No.1 Hospital from March 2018 to September 2022 were retrospectively included. The patients were divided into a MATHE group and a FMIE group according to the procedures. The patients were matched via propensity score matching (PSM) with a ratio of 1 : 1 and a caliper value of 0.2. The clinical data of the patients were compared after the matching. Results A total of 73 patients were include in the study, including 54 males and 19 females, with an average age of (65.12±7.87) years. There were 37 patients in the MATHE group and 36 patients in the FMIE group. Thirty pairs were successfully matched. Compared with the FMIE group, MATHE group had shorter operation time (P=0.022), lower postoperative 24 h pain score (P=0.031), and less drainage on postoperative 1-3 days (P<0.001). FMIE group had more lymph node dissection (P<0.001), lower incidence of postoperative hoarseness (P=0.038), lower white blood cell and neutrophil counts on postoperative 1 day (P<0.001). There was no statistically significant difference in the bleeding volume, R0 resection, hospital mortality, postoperative hospital stay, anastomotic leak, chylothorax, or pulmonary infection between the two groups (P>0.05). Conclusion Compared with the FMIE, MATHE has shorter operation time, less postoperative pain and drainage, but removes less lymph nodes, which is deficient in oncology. For some special patients such as those with early cancer or extensive pleural adhesions, MATHE may be a suitable surgical method.

【Objective】 To investigate the relationship between serum reproductive hormones and sperm parameters and outcomes of micro-testicular sperm extraction (Micro-TESE). 【Methods】 Clinical data of 1 091 patients treated in our hospital during Jan. and Dec.2021 were retrospectively analyzed. According to the sperm concentration,the patients were divided into non-obstructive azoospermia (NOA) group (group A,n=418),normal sperm concentration group (group B,n=615),mild to moderate oligospermia group (group C,n=18),severe oligospermia group (group D,n=18),and obstructive azoospermia group (group E,n=22). In group A,244 cases treated with Micro-TESE were grouped into the sperm-acquired group (Micro-TESE positive group,n=82) and non-sperm-acquired group (Micro-TESE negative group,n=162),and according to the pathological types of testicular tissue,the patients were divided into normal testicular tissue with hypospermatogenesis group (HYPO group,n=129),maturation arrest group (MA group,n=10),and support-only cell syndrome group (SCO group,n=122). Differences in semen parameters and reproductive hormone levels were compared,and relationship between reproductive hormones and sperm parameters and Micro-TESE outcomes was determined with Pearson correlation analysis. 【Results】 In the sperm concentration subgroup,the testicular volume of group A was lower than that of group B and group E (P<0.05); the levels of follicle stimulating hormone (FSH) and luteinizing hormone (LH) in group A were the highest (P<0.05),but the level of testosterone (T) was the lowest (P<0.05); the levels of anti-mullerian hormone (AMH) and serum inhibin B (INHB) in group A were lower than those in group B and group E (P<0.05),the normal sperm morphology rate in group B was higher than that in group A and group E (P<0.05); the percentage of forward moving sperm in group B was the highest (P<0.05). Pearson correlation analysis revealed that sperm concentration,normal sperm morphology rate,and percentage of forward moving sperm were negatively correlated with age,FSH,LH (P<0.05),and positively correlated with testicular volume,T,AMH,and INHB (P<0.05). NOA patients were grouped according to testicular histology and pathology. The INHB in the SCO group was the smallest of the three groups (P<0.05); the FSH and LH levels in the SCO group were higher than those in the MA group (P<0.05),while the 17β-estradiol (E2) levels in the HYPO group were higher than those in the SCO group (P<0.05). NOA patients were grouped according to the results of Micro-TESE surgical treatment. There was a statistically significant difference in AMH and INHB levels between the Micro-TESE positive and negative groups (P<0.05). The binary logistic regression analysis of factors affecting the Micro-TESE outcomes of NOA patients showed AMH was negatively correlated with the Micro-TESE outcome (OR=0.904,95%CI:0.91-1.08,P<0.05). 【Conclusion】 Age,FSH,LH,AMH,and INHB are correlated with sperm concentration,normal sperm morphology rate,and percentage of forward moving sperm. The INHB level was the lowest in the SCO group. The results of Micro-TESE in patients with NOA can be predicted by serum AMH level.

Objective:To explore the role of an exosomal long non-coding RNA zinc finger E-box-bingding homeobox 1 antisense 1(ZEB1-AS1) from adipose-derived MSC(adMSC) and its action mechanism in DN.Methods:DN rat model and high glucose(HG)-induced glomerular mesangial cell(GMCs) model treated with exosomal ZEB1-AS1 from adMSC were used for biochemical analysis and inflammation/oxidative stress assessment. The binding relationships among ZEB1-AS1, microRNA(miR)-142-5p, and phosphatase and tensin homolog deleted on chromosome 10(PTEN) were confirmed by dual luciferase reporter assay. Western blotting was used for the measurement of PTEN protein level.Results:adMSC-secreted exosomal ZEB1-AS1 reduced the levels of blood glucose, serum creatinine, 24 h urinary protein, kidney weight, fibrosis, and inflammatory cell infiltrations in DN rats. Meanwhile, both in DN rats and HG-induced GMCs, the levels of tumor necrosis factor(TNF)-α, interleukin(IL)-6, and IL-1β were inhibited, but glutathione peroxidase(GPx), superoxide dismutase(SOD), catalase(CAT), and glutathione(GSH) were promoted by exosomal ZEB1-AS1 treatment. Additionally, miR-142-5p was identified to bind to ZEB1-AS1, while miR-142-5p further targeted PTEN. miR-142-5p overexpression or PTEN silencing reversed the inhibiting effects of exosomal ZEB1-AS1 on inflammatory cytokine levels and the promoting effects on the concentrations of antioxidant enzymes.Conclusion:Exosomal ZEB1-AS1 from adMSC prevents DN progression by controlling inflammation and oxidative stress via the miR-142-5p/PTEN pathway, suggesting that ZEB1-AS1 may serve as a potential and effective therapeutic target for treating DN.

Objective:To understand the current situation of nurses in 52 hospitals in China on mastery of knowledge about skin injury in the elderly based on the background of mixed-mode homogenization training.Methods:Using the convenient sampling method, a total of 1 067 nurses from 52 hospitals in China were selected as the research objects in January 2021. A self-designed questionnaire on knowledge of skin injury in the elderly was used to investigate the nurses through the questionnaire star and univariate analysis was used to analyze the influencing factors. A total of 1 067 questionnaires were distributed and 1 067 valid questionnaires were recovered, and the effective recovery rate was 100%.Results:The knowledge scores of pressure injury, incontinence-associated dermatitis, skin tear and xerosis cutis among 1067 nurses were (95.66±7.37) , (95.65±9.15) , (91.37±15.45) and (87.67±15.91) , respectively. The results of univariate analysis showed that hospital grade was the influencing factor of nurses' knowledge score of pressure injury, skin tear and incontinence-associated dermatitis ( P<0.05) , educational background was the influencing factor of nurses' knowledge score of skin tear ( P<0.05) , professional title was the influencing factor of nurses' knowledge scores of pressure injury, incontinence-associated dermatitis and xerosis cutis ( P<0.05) . Conclusions:Hospitals at all levels need to strengthen the theoretical and practical knowledge training for nurses on skin xerosis and skin tear in the elderly, especially for nurses with primary titles and lower education in grassroots hospitals.
