This article presents a case study of a patient who visited the Geriatric Department of Peking Union Medical College Hospital due to "palpitations, shortness of breath for more than 2 years, limb weakness for 6 months, edema, and nocturnal dyspnea for 2 months". The patient exhibited decreased muscle strength in the limbs and involvement of swallowing and respiratory muscles, alongside complications of heart failure and various arrhythmias which were predominantly atrial. Laboratory tests revealed the presence of multiple autoantibodies and notably anti-mitochondrial antibodies. Following a comprehensive multidisciplinary evaluation, the patient was diagnosed with anti-mitochondrial antibody-associated inflammatory myopathy. Treatment involved a combination of glucocorticoids and immunosuppressants, along with resistance exercises for muscle strength and rehabilitation training for lung function, resulting in significant improvement of clinical symptoms. The case underscores the importance of collaborative multidisciplinary approaches in diagnosing and treating rare diseases in elderly patients, where careful consideration of clinical manifestations and subtle abnormal clinical data can lead to effective interventions.

ObjectiveTo analyze the drug resistance and the molecular typing characteristics through pulsed field gel electrophoresis (PFGE) of Campylobacter spp. isolated from patients with infectious diarrhea in Baoshan District of Shanghai, and to provide a basis for Campylobacter spp. prevention and control and clinical medication. MethodsCampylobacter spp. was isolated, cultured and identified from stool samples of diarrheal patients collected from medical institutions at two monitoring sites in Baoshan District from 2019 to 2022. Antimicrobial susceptibility testing for 12 antibiotics was conducted on the isolated Campylobacter jejuni (C. jejuni) and Campylobacter. Coli (C. coli), and molecular typing was performed using PFGE. ResultsA total of 179 strains of Campylobacter spp. were isolated from 1 786 samples of diarrheal patients, with a positive rate of 10.02%. The highest resistance rate of C. jejuni was to ciprofloxacin (98.63%), followed by tetracycline (97.26%) and nalidixic acid (89.73%). C. coli was completely resistant to ciprofloxacin and nalidixic acid (100.00%), followed by tetracycline (90.91%). The multidrug resistance rates of C. jejuni and C. coli were 89.73% and 100.00%, respectively. 142 strains of C. jejuni produced 122 PFGE bands, while 33 strains of C. coli produced 33 PFGE bands, and the distribution of the bands was relatively dispersed. ConclusionFrom 2019 to 2022, the detection rate of Campylobacter in diarrheal patients was relatively high in Baoshan District of Shanghai, the multidrug resistance rate of Campylobacter isolates from diarrheal patients was relatively serious, in addition, the drug resistance pattern was complex, and the PFGE band pattern displayed a polymorphic distribution.

Objective:To investigate the value of soluble interleukin-6 (IL-6) receptor (sIL-6R) level in predicting ultrafiltration insufficiency in peritoneal dialysis (PD) patients.Methods:It was a prospective cohort study. The patients who received continuous ambulatory PD and regular follow-up between November 2016 and July 2018 in the PD Center of Renji Hospital, School of Medicine, Shanghai Jiao Tong University were enrolled. Enzyme-linked immunosorbent assay was used to determine dialysate sIL-6R and its appearance rate (AR) was calculated. Patients were divided into high sIL-6R AR group and low sIL-6R AR group according to median value of sIL-6R AR and prospectively followed up until death, PD cessation, or the end of the study (December 31, 2022). Multiple linear regression was used to analyze the related factors of sIL-6R AR. Kaplan-Meier method and log-rank test were used to compare the survival rate difference of ultrafiltration insufficiency between high sIL-6R AR group and low sIL-6R AR group. Multivariate Cox regression and multivariate competing risk models were used to assess the risk factors associated with occurrence of ultrafiltration insufficiency.Results:A total of 198 PD patients were enrolled, including 115 (58.1%) males, with age of (54.9±13.7) years old and PD duration of 22.5 (6.6, 65.0) months. The sIL-6R AR of the cohort was 2 094.7 (1 672.4, 2 920.9) pg/min. Compared with low sIL-6R AR（<2 094.7 pg/min）group, high sIL-6R AR（>2 094.7 pg/min）group had older age ( t=-3.269, P=0.001), higher body mass index ( t=-3.248, P=0.001), proportion of combined diabetes mellitus ( χ2=8.890, P=0.003), 24 h glucose exposure ( Z=-2.257, P=0.024), 24 h ultrafiltration capacity ( Z=-2.515, P=0.012), 4 h dialysate creatinine to serum creatinine ratio ( t=-2.609, P=0.010), mass transfer area coefficient of creatinine ( Z=-2.308, P=0.021), IL-6 AR ( Z=-3.533, P<0.001) and solute glycoprotein 130 AR ( Z=-8.670, P<0.001), and lower serum albumin ( t=2.595, P=0.010) and residual renal function ( t=2.133, P=0.033). Multiple linear regression analysis showed that body mass index ( β=0.194, P=0.005), serum albumin ( β=-0.215, P=0.002) and dialysate lg[IL-6 AR] ( β=0.197, P=0.011) were independently correlated with sIL-6R AR. By the end of the study, 57 (28.8%) patients developed ultrafiltration insufficiency. Kaplan-Meier analysis showed that high sIL-6R AR group had a significantly inferior ultrafiltration insufficiency-free survival rate than that in low sIL-6R AR group (log-rank χ 2=5.375, P=0.020). Multivariate Cox regression analysis and multivariate competing risk models showed that high dialysate sIL-6R AR (>2 094.7 pg/min) was an independent influencing factor of ultrafiltration insufficiency ( HR=2.286 , 95% CI 1.254-4.165 , P=0.007 ; SHR=2.074, 95% CI 1.124-3.828, P=0.020) in PD patients. Conclusions:Dialysate sIL-6R level was associated with body mass index, serum albumin and dialysate IL-6 level. Dialysate sIL-6R may be a predictive factor of ultrafiltration insufficiency in PD patients.

Element doping is one of the strategies for increasing the activity of enzyme-like materials.In this study,cobalt,nitrogen and chlorine-doped carbon dots(Co,N,Cl-CDs)were prepared by one-step hydrothermal synthesis utilizing CoCl2 and glutamate as raw ingredients.In weakly acidic environments,Co,N,Cl-CDs exhibited high peroxidase-like activity and could catalyze the oxidation of 3,3′,5,5′-tetramethylbenzidine(TMB)by hydrogen peroxide into oxided TMB(oxTMB),resulting in a distinct color change.Free radical scavenging and electron spin resonance techniques were used to further investigate the catalytic reaction mechanism of Co,N,Cl-CDs,and the reactive intermediates produced during the reaction were identified as hydroxyl radical.Acid phosphatase(ACP)could catalyze the hydrolysis of sodium ascorbyl phosphate to release ascorbic acid,which could reduce the blue oxTMB into colorless TMB.Based on this principle,a colorimetric-switching sensing system for detection of ACP was developed by coupling Co,N,Cl-CDs and ACP.The sensing system demonstrated good linearity in ACP activity range of 0.5-20 U/L,with a detection limit of 0.17 U/L.The developed sensing system was used to detection of ACP in real serum samples with good recoveries(97.1%-105.7%)and reproducibility(RSD<5%).The sensing system developed here based on Co,N,Cl-CDs had many advantages such as low detection cost,process visualization,and high sensitivity,providing reference for detection of ACP.

Objective:To investigate the efficacy of sufentanil combined with butorphanol and sufentanil combined with dezocine for postoperative analgesia of single-port thoracoscopic lobectomy.Methods:A prospective randomized controlled study was conducted. A total of 72 patients who underwent single-port thoracoscopic lobectomy in Shanxi Province Cancer Hospital from October to December 2023 were prospectively selected, and the patients were divided into group A and group B according to randomized numerical table method, with 36 cases in each group. Group A used sufentanil combined with dezocine for postoperative analgesia; group B used sufentanil combined with butorphanol for postoperative analgesia. The visual analogue scale (VAS) scores of pain, Ramasy sedation scores, vital signs monitoring indexes, postoperative adverse reactions, and the time of removing the closed chest drain were compared between the two groups at different time points in the postoperative period.Results:There were 20 males (55.6%) and 16 females (44.4%) in group A, aged (58±10) years old; there were 16 males (44.4%) and 20 females (55.6%) in group B, aged (56±11) years old; there were no statistically significant differences between the two groups in terms of gender, age, body mass index, American Society of Anesthesiologists classification, and surgery time (all P > 0.05). Comparison of the VAS scores of the two groups at 2, 6 and 10 h after surgery showed no statistically significant differences (all P > 0.05); the VAS scores of group B at 12, 24 and 48 h were lower than those of group A, and the differences were statistically significant (all P < 0.01). The Ramasy scores of the patients in group B at 2, 6, 10, 12, 24, and 48 h after surgery were higher than those of group A, and the differences were statistically significant (all P < 0.05). The postoperative chest drain removal time in group A was (4.5±1.7) d, which was longer than that in group B [(3.7±0.8) d], and the difference was statistically significant ( t= 2.58, P = 0.014). Comparison of systolic blood pressure, diastolic blood pressure, oxygen saturation, heart rate, and respiration of patients in the two groups at 2, 6, 10, 12, 24, and 48 h after surgery showed no statistically significant differences (all P > 0.05). The incidence of postoperative adverse reactions in patients of both groups was 16.67% (6/36). Conclusions:The efficacy of sufentanil combined with butorphanol for postoperative analgesia of single-port thoracoscopic lobectomy is better than that of sufentanil combined with dezocine, which may help to accelerate the patient's postoperative recovery.Objective To investigate the efficacy of sufentanil combined with butorphanol and sufentanil combined with dezocine for postoperative analgesia of single-port thoracoscopic lobectomy.

Objective:To study the expression level of peripheral blood microRNA(miRNA)-21 and miRNA-192 in patients with papillary thyroid carcinoma (PTC) and their relationship with pathological features and prognosis.Methods:A total 107 PTC patients admitted to Huaian Cancer Hospital in Jiangsu Province from June 2018 to June 2021 were selected as the PTC group, another 76 healthy individuals who underwent physical examination during the same period were selected as the control group. Real-time fluorescence quantitative PCR (qRT-PCR) was used to measure the expression levels of miRNA-21 and miRNA-192 in the peripheral blood of two populations, and the expression of miRNA-21 and miRNA-192 in the peripheral blood of the two populations and patients with different characteristics was compared and analyzed. Kaplan-Meier (K-M) method was used to analyze the relationship between the expression levels of miRNA-21, miRNA-192 in peripheral blood of PTC patients and prognosis.Results:The expression level of miRNA-21 in the peripheral blood of patients in the PTC group (2.21 ± 0.64) was higher than that in the control group (1.01 ± 0.02), while miRNA-192 (0.42 ± 0.14) was lower than that in the control group (0.99 ± 0.03, t = 16.33, 34.90, P < 0.001). In different clinical stages, the expression level of miRNA-21 in peripheral blood of patients in stages Ⅲ - Ⅳ was higher than that in stages Ⅰ - Ⅱ, and the level of miRNA-192 was lower than that in stages Ⅰ - Ⅱ ( t = 9.98, 11.75, P < 0.001). In the case of lymph node metastasis, the expression level of miRNA-21 in peripheral blood of patients with lymph node metastasis was higher than that of the group without lymph node metastasis, and the level of miRNA-192 was lower than that of the group without lymph node metastasis ( t = 12.81, 18.75, P < 0.001). There was no statistically significant difference in the expression levels of miRNA-21 and miRNA-192 in peripheral blood of patients with different genders, ages, body mass index, and tumor sizes ( t = 0.57, 0.42, 0.54, 0.62, 1.15, 1.47, 0.74, 1.13, P > 0.05). The K-M survival curve results showed that the progression free survival time (39.02 months) with high miRNA-21 expression was lower than that with low miRNA-21 expression (55.97 months, P = 0.026); the progression free survival time (34.97 months) with low miRNA-192 expression was lower than that with high miRNA-192 expression (57.04 months, P = 0.008). Conclusion:The high expression of miRNA-21 and low expression of miRNA-192 in peripheral blood of PTC patients, and they are closely related to the clinical stage, lymph node metastasis, and prognosis of patients.

Objective:To explore the impact of rehabilitation exercise intervention mode based on cardiac function classification on clinical effect and quality of life(QOL)in patients with chronic heart failure(CHF).Methods:A total of 160 CHF patients who visited our hospital from Dec 2021 to Jan 2023 were selected,and 154 cases were fi-nally enrolled.According to the random number table method,patients were divided into study group and control group with 77 cases in each group.Control group received routine nursing program,while the study group received rehabilitation exercise intervention based on cardiac function classification on the basis of control group,both groups were intervened for three months.Clinical total effective rate,and cardiopulmonary function,serum oxidative stress indicators and MLHFQ score before and after intervention were compared between two groups.Results:Total effective rates of study subgroups of class Ⅱ and Ⅲ were significantly higher than those of control group(class Ⅱ:100.00％vs.83.78％;class Ⅲ:97.37％vs.80.00％)(P＜0.05 both).Compared with control subgroup of classⅢ after intervention,there were significant rise in peak VO2[(16.98±2.03)ml·min-1·kg-1 vs.(18.61±2.41)ml·min-1·kg-1],LVEF[(41.73±4.53)％vs.(48.03±5.22)％]and 6MWD[(351.34±61.00)m vs.(391.53±64.42)m](P＜0.01 all);and significant reductions in LVEDd[(57.55±3.91)mm vs.(53.18±3.07)mm],LVESd[(35.90±2.91)mm vs.(30.50±2.67)mm],levels of LPO[(6.00±0.99)mg/L vs.(3.95±0.61)mg/L],MPO[(3.83±0.58)mg/L vs.(2.03±0.28)mg/L],and MLHFQ total score[(57.05±4.57)points vs.(45.29±3.94)points]in study subgroup of class Ⅲ(P=0.001 all).Compared with control subgroup of class Ⅱ after intervention,there were significant rise in peak VO2,LVEF and 6MWD,and significant reductions in LVEDd,LVESd,levels of LPO,MPO and MLHFQ score in study subgroup of class Ⅱ,P＜0.05 or＜0.01.There was no significant difference in the incidence rate of adverse events during follow-up between two groups(3.90％vs.6.49％,P=0.717).Conclusion:Rehabilitation exercise intervention based on cardiac function classifi-cation can significantly improve cardiopulmonary function,inhibit oxidative stress response in vivo and improve quality of life in CHF patients,which is worthy of promotion and application in clinical practice.

Objective To evaluate the clinical effect of Tension-free laparoscopic lateral suspension with mesh for pelvic organ prolapse.Methods A total of 85 patients who underwent pelvic organ prolapse were selected as the study group,and 40 patients underwent Laparoscopic sacral fixation surgery(LSC)as the control group in Henan Provincial People's Hospital from March 1,2021 to October 31,2023.The patients were divided into two subgroups:uterine preservation group and uterine resection group and followed up until April 30,2024.The intra-operative conditions and postoperative complications were recorded and analyzed.POP quantitative staging(POP-Q)scores were used for evaluation.Preoperative and postoperative quality of life and therapeutic effect were evaluated using the pelvic floor distress inventory short form-20(PFDI-20),urinary distress inventory-6(UDI-6),colorectal-anal distress inventory-8(CRADI-8),pelvic organ prolapse distress inventory-6(POPDI-6),pelvic floor impact questionnaire-7(PFIQ-7),prolapse and Incontinence sexual function questionnaire short form(PISQ-12).Results The median follow-up time for patients in the study group is 13.13 months,with an objective cure rate of 96.47%and a reoperation rate of 1.18%.The perioperative complication rates are 6.45%for uterine resection and 4.35%for uterine preservation,while the mesh exposure rate is 1.61%for uterine resection.In comparison,the median follow-up time for patients in the control group is slightly longer at 13.76 months,with an objective cure rate of 92.5%and a reoperation rate of 2.5%.The perioperative complication rates are higher at 14.71%for uterine resection and as high as 33.33%for uterine preservation,while the mesh exposure rate is also elevated at 8.82%for uterine resection.Despite these differences,there was no significant disparity in objective cure rates or reoperation rates between the study group and the control group.Furthermore,it was observed that the study group experienced shorter operation times,less bleeding,faster postoperative recovery,shorter hospitalization periods,lower perioperative complications,and reduced mesh exposure rates-especially among patients with uterine preservation.Additionally,intra-group comparisons revealed significant improvements in all POP-Q indicators one year after surgery(P<0.05),along with significantly lower scores on PFDI-20,UDI-6,CRADI-8,POPDI-6,PFIQ-7,and PISQ-12 scales com-pared to pre-surgery levels(P<0.05).However,no significant inter-group differences were noted.Conclusions Tension-free laparoscopic lateral suspension with mesh proves to be an effective surgical approach for treating ante-riorand middle pelvic organ prolapse.It demonstrates few perioperative complications while significantly improving prolapse symptoms and enhancing patient qualityof life.It stands as a viable alternative to sacrocolpopexy,particu-larly beneficial for patients with a preserved uterus.

Objective To explore the clinical characteristics of pediatric patients with cerebral palsy(CP)who also have comorbid epilepsy.Methods A retrospective analysis was conducted on the clinical data of 155 pediatric patients with CP and comorbid epilepsy admitted to the Third Affiliated Hospital of Zhengzhou University from January 2019 to December 2022.Patients were divided into 4 groups based on CP subtype:spastic diplegia group(n=29),spastic hemiplegia group(n=33),spastic quadriplegia group(n=73),and non-spastic group(n=20).Differences in sex,season of birth,birth weight,gestational age,and the relationship between gestational age and weight were compared among the groups.Additionally,the relationships between perinatal risk factors,MRI classification system(MRICS),gross motor function classification system(GMFCS),and the age of the first onset of epilepsy with respect to CP subtype were analyzed.Results Among the 155 patients,101 were male and 54 were female.A lower proportion of patients with spastic hemiplegia was observed with a gestational age of 28-31+6 weeks compared with those with spastic diplegia and spastic quadriplegia(P=0.009).The proportion of patients with a history of asphyxia in spastic hemiplegia group was significantly lower than that in the other 3 groups,and the proportion of patients with hypoxic-ischemic encephalopathy(HIE)in spastic hemiplegia group was significantly lower than in that both spastic quadriplegia group and non-spastic group(P<0.05).The proportion of patients in spastic quadriplegia group who had their first seizure at an age of<1 year was significantly higher than that in spastic diplegic group(P=0.041).The spastic diplegia group exhibited a higher percentage of white matter damage compared with the other 3 groups,and had a lower percentage of gray matter damage compared with both spastic hemiplegic group and non-spastic group(P=0.001).The proportion of patients with GMFCS levels Ⅳ-Ⅴ in spastic quadriplegia group was higher than those in the other 3 groups(P<0.001),and the proportion of patients with levels Ⅰ-Ⅲ in spastic hemiplegia group was significantly higher than those in spastic quadriplegia group and non-spastic group(P<0.001).Conclusion Significant differences were observed among pediatric patients with different subtypes of CP and comorbid epilepsy in factors such as gestational age,history of asphyxia,HIE history,age of first seizure,MRICS classification and GMFCS levels.

Objective To investigate the current situation of achievement transformation in tertiary medical hospitals in Shanghai and propose countermeasures for the existing problems to enhance the effectiveness of achievement transformation.Methods A questionnaire survey was done on the transformation and management of scientific research achievements in 47 terti-ary hospitals in Shanghai.Meanwhile,interviews were carried out among the managers and researchers from these hospitals.Re-sults In the past three years,the rate of transformation achievements in the hospitals was only 2.8%.In the achievement trans-formation existed such problems as weak awareness of scientific researchers,low patent quality,lack of full-time managers,and inflexible management mode.It was also believed that there is a need to improve main responsibilities,achievement management,system establishment,personnel training,resource sharing,department coordination and other related aspects.Conclusion The rate of achievement transformation in tertiary medical institutions in Shanghai is at a lower level.There are numerous problems and difficulties in the transformation.Therefore,urgent efficient countermeasures are needed to promote the transformation of a-chievement.
