Objective:To observe the effect of isokinetic sensorimotor training on the hand function of stroke survivors.Methods:Forty-two stroke survivors with hand dysfunction were randomly divided into an isokinetic group of 22 and a control group of 20. Both groups were given sensorimotor training in addition to routine drug treatment and rehabilitation therapy, but the isokinetic group was additionally provided with sensorimotor training based on isokinetic techniques for 45 minutes daily, 5 days a week for 4 consecutive weeks. Before and after the intervention, both groups were evaluated using the Semmes-Weinstein monofilament examination (SWME), their two-point discrimination (2-PD) was documented, proprioception of their wrist joints was quantified, and the Fugl-Meyer upper extremity assessment (FMA-UE) and the simplified upper limb function assessment (STEF) were applied.Results:In both groups after treatment, there was a significant improvement in the SWME scores and 2-PD distance of the index finger and the thenar, and there was a significant decrease in the angle of motion perception (at 30° of flexion). The average FMA-UE and STEF scores of both groups had improved. After the treatment, the SWME scores of the index finger and the thenar, as well as well as the average FMA-UE and STEF scores of the isokinetic group were significantly higher than the control group′s averages. Angle of motion perception was also significantly superior.Conclusions:Sensorimotor training based on isokinetic techniques can significantly improve touch, motion sense, gross motor function and the fine motor ability of stroke survivors.

Objective:To investigate the effects of long non coding RNA KCNQ1OT1(LncRNA KCNQ1OT1)on the migration and invasion of oral squamous cell carcinoma(OSCC)cells by regulating the microRNA-875-5p(miR-875-5p)/ETS like transcription factor 4(ELK4)axis.Methods:QRT-PCR was applied to detect the mRNA levels of LncRNA KCNQ1OT1,miR-875-5p,and ELK4 in OSCC cell lines(HSC-3,PE/CA-PJ15,HN13)and tissues.The dual luciferase assay was applied to detect the targeting relationship between LncRNA KCNQ1OT1 and miR-875-5p,and target relationship between miR-875-5p and ELK4.HSC-3 cells were used in control group,sh-NC group,sh-KCNQ1OT1 group,sh-KCNQ1OT1+anti-NC group,sh-KCNQ1OT1+anti-miR-875-5p group,miR-NC group,miR-875-5p mimic group,miR-875-5p mimic+pcDNA-NC group,and miR-875-5p mimic+ELK4 group.The migration and invasion abilities of HSC-3 cells were detected.Immunoblotting was applied to detect the protein expression of ELK4,MMP-2,MMP-9 and epithelial mesenchymal transition(EMT)(E-Cadherin,N-Cadherin,Vimentin).The nude mouse transplant tumor was applied to verify the effect of LncRNA KCNQ1OT1 on OSCC transplant tumors.Results:LncRNA KCNQ1OT1 and ELK4 mRNA expression increased in OSCC tissues and cancer cell lines,while miR-875-5p expression decreased(P＜0.05).Database predictions show that miR-875-5p specifically bound to LncRNAs KCNQ1OT1 and ELK4,respectively.Compared with the sh-NC group,the numbers of cell migration and cell invasion,the expression of LncRNA KCNQ1OT1,ELK4,MMP-2,MMP-9,N-Cadherin,and Vimentin in the sh-KC-NQ1OT1 group were lower,while the expression of miR-875-5p and E-Cadherin was higher(P＜0.05).Compared with the sh-KC-NQ1OT1+anti-NC group,the expression of miR-875-5p and E-Cadherin in the sh-KCNQ1OT1+anti-miR-875-5p group was lower,while the numbers of cell migration and cell invasion,the expression of ELK4,MMP-2,MMP-9,N-Cadherin,and Vimentin were higher(P＜0.05).Compared with the miR-NC group,the expression of miR-875-5p and E-Cadherin in the miR-875-5p mimic group was higher,while the numbers of cell migration and cell invasion,the expression of ELK4,MMP-2,MMP-9,N-Cadherin,and Vim-entin were lower(P＜0.05).Compared with the miR-875-5p mimic+pcDNA-NC group,the numbers of cell migration and cell inva-sion,the expression of ELK4,MMP-2,MMP-9,N-Cadherin,and Vimentin in the miR-875-5p mimic+ELK4 group were higher,while the expression of E-Cadherin was lower(P＜0.05).The transplant tumor volume and weight of the sh-KCNQ1OT1 group were smaller than those of the sh-NC group,the mRNA and protein expression levels of LncRNA KCNQ1OT1,ELK4 were lower than those of the sh-NC group,and the expression level of miR-875-5p was higher than that of the sh-NC group(P＜0.05).Conclusion:Inhibition of LncRNA KCNQ1OT1 can target the miR-875-5p/ELK4 axis to inhibit migration,invasion,and EMT of OSCC cells.

Objective:To compare the efficacy of radial forearm flap and anterolateral thigh flap in repairing soft tissue defects after oral cancer surgery and to explore their indications.Methods:A retrospective analysis was conducted on clinical data of patients with oral cancer treated at the Department of Stomatology, Affiliated Hospital of Nantong University, from May 2019 to February 2023. Patients were divided into two groups based on the repair method: the radial forearm flap group and the anterolateral thigh flap group. The groups were compared in the following aspects. (1) Surgical parameters including defect area after oral cancer resection, flap area, flap preparation time, operation time, and length of hospital stay. (2) Inflammatory markers (interleukin-6 and C-reactive protein levels) measured 1 day before surgery and 1 day after surgery. (3) Flap survival rate was calculated. (4) Complication rates was calculated in the flap donor area and infection rates in the oral recipient area within 6 months postoperatively. (5) Six months postoperatively, the patient’s oral function was assessed by a physician using the University of Washington quality of life scale (UW-QOL). The evaluation included assessments of oral opening, speech, and eating functions. Each parameter was scored on a scale of 0 to 10 (higher scores indicated better recovery). (6) Quality of life was assessed using the 36-item short form health survey scale(SF-36) at 2, 4 and 6 months postoperatively, with scores ranging from 0 to 100 (higher scores indicated better quality of life). (7) Patient satisfaction was assessed at 6 months postoperatively, with satisfaction levels categorized as satisfied, basically satisfied, and dissatisfied. The satisfaction rate was calculated as (satisfied + basically satisfied ) cases / total cases in each group × 100%. Statistical analysis was performed using SPSS 22.0. Measurement data were expressed as Mean±SD, and comparisons between groups were conducted using t-tests. Count data were expressed as cases and (or) percentages, and comparisons were made using chi-square test. P<0.05 was considered statistically significant. Results:The radial forearm flap group included 48 cases (32 males, 16 females), aged (49.3±5.0) years, with a body mass index (BMI) of (23.0±1.1) kg/m 2 and a disease course of (6.5±2.1) months. The group had 21 cases of tongue cancer, 12 of floor of mouth cancer, and 15 of buccal cancer, including 40 squamous cell carcinomas and 8 basal cell carcinomas. The anterolateral thigh flap group included 32 cases (20 males, 12 females), aged (50.1±5.0) years, with a BMI of (23.0±1.0) kg/m 2 and a disease course of (7.0±2.2) months. The group had 16 cases of tongue cancer, 7 cases of floor of mouth cancer, and 9 cases of buccal cancer, including 27 squamous cell carcinomas and 5 basal cell carcinomas. There were no significant differences in gender, age, BMI, disease course, tumor location, or pathological type between the two groups ( P>0.05). The defect area after oral cancer resection was smaller in the radial forearm flap group[ (39.0±1.3) cm 2 ] compared to the anterolateral thigh flap group[ (40.3±2.2) cm 2] ( t=3.32, P=0.001). There were no significant differences in flap area, flap preparation time, or length of hospital stay between the two groups ( P>0.05). The operation time was shorter in the radial forearm flap group [(5.1±1.1) h] compared to the anterolateral thigh flap group [(6.8±2.8) h] ( t=0.26, P<0.001). There were no significant differences in interleukin-6 and C-reactive protein levels between the two groups 1 day before surgery and 1 day after surgery ( P>0.05). The flap survival rates were 97.9% (47/48) in the radial forearm flap group and 93.8% (30/32) in the anterolateral thigh flap group, with no significant difference( P>0.05). Postoperative donor site complications mainly included infection, pigmentation, itching, etc. The overall incidence of complications in the donor site of the radial forearm flap [33.3% (16/48)] was higher than that in the anterolateral thigh flap group [12.5% (4/32)], and the difference was statistically significant ( χ2=4.44, P=0.035). There was no significant difference in infection rates in the oral recipient area between the two groups ( P>0.05). Six months postoperatively, the average scores for oral opening, speech, and eating functions were above 7 in both groups, with no significant differences ( P>0.05). Quality of life scores improved over time in both groups, with average scores above 90 at 6 months postoperatively, and no significant differences at any time point ( P>0.05). The patient satisfaction rate was 91.7% (44/48) in the radial forearm flap group and 90.6% (29/32) in the anterolateral thigh flap group, with no significant difference ( P>0.05). Conclusion:Both radial forearm flap and anterolateral thigh flap can effectively repair soft tissue defects after oral cancer resection, significantly improving patients’oral function. The anterolateral thigh flap provides sufficient tissue volume and is suitable for patients with larger defect areas. The radial forearm flap is suitable for patients with a smaller defect area after oral cancer resection. Its surgical procedure is relatively less complex and offers an advantage in reducing surgery time. However, the donor site complications are higher with the radial forearm flap compared to the anterolateral thigh flap.

Chronic kidney disease (CKD) is a serious health problem worldwide, whereas there is still no efficient cure. The gut microbiota plays a crucial role in maintaining human health and disease resistance, and multiple studies have confirmed that the gut microbiota is closely related to the occurrence and development of CKD. Starting from the "gut-kidney axis" theory, this article provides a systematic review of the changes in gut microbiota composition and function in patients with CKD, such as a decrease in the abundance of butyrate-producing bacteria Roseburia and Faecalibacterium prausnitzii. Besides that, the article explores the mechanisms by which the gut microbiota affects CKD progression, such as inflammation and immunity, and also describes the application methods of using the gut microbiota as a therapeutic target for CKD, such as fecal microbiota transplantation, microecologics, and dietary therapy, in order to provide microbial- based targets for the clinical diagnosis and treatment of CKD.

To explore the effect of BBT-I on subjective insomnia and its influencing factors. Methods 60 primary insomnia patients were collected in outpatient department，and divided into two groups：Subjective insomnia group （SI group） and non-subjective insomnia group （NSI group） by sleep data collected by standard polysomnography monitoring and Pittsburgh Sleep Quality Index （PSQI），sleep diaries during the intervention were collected，and the Pre Sleep Arousal Scale（PSAS），Brief Version of Dysfunctional Beliefs and Attitudes About Sleep （DBAS） and the Sleep Hygiene Practice Scale（SHPS） were collected to evaluate the influencing factors related to sleep attitudes，beliefs and behaviors of patients. All patients received BBT-I for 4 weeks，and collected the sleep diaries and PSQI 1 week before and 1 week after treatment. Results Compared with NSI group，SI group had higher arousal index（P<0.05）；compared with NSI group，SI group had lower scores in factor 3 indicated as drug belief and factor 4 representing anticipation of sleep in DBAS，that is，there were more irrational beliefs in SI （P<0.05）.Intragroup comparison showed that there were statistically significant differences insleep latency、sleep efficiency，daytime function and PSQI score in SI group before and after treatment （P<0.05），and there were statistically significant differences in SE difference before and after intervention between SI group and NSI group （P<0.05）.In the subjective insomnia group，daytime functional difference before and after intervention was negatively correlated with the first factor in DBAS（r=0.270，P=0.037）. daytime functional difference before and after intervention was negatively correlated with PSAS（r=0.268，P=0.039）；The difference of sleep latency before and after intervention was negatively correlated with physiological stimulation of PSAS（r =0.288，P=0.042）. Conclusion Compared with nonsubjective patients，subjective insomnia patients have higher arousals and more irrational beliefs and attitudes.BBT-I may improve sleep latency/、sleep efficiency，daytime function and sleep sensation in subjective insomnia patients.

Objective:To explore the application of peritoneal dialysis routine examination in reducing the incidence of peritonitis associated with peritoneal dialysis.Methods:From July 2018 to June 2019, 191 patients with peritoneal dialysis who were followed up regularly in the nephrology department were selected as the study subjects.Using convenient sampling method, outpatient follow-up on Tuesday were selected as control group(95 cases) and fixed outpatient follow-up on Thursday were selected as observation group(96 cases). Routine follow-up was performed in the control group, and routine examination of peritonitis was performed in the observation group during the follow-up.Intervention was given immediately when the problems were found to the naked eye and the examination results were abnormal.The incidence of peritonitis in the two groups was compared.Results:Peritonitis occurred in 24 cases in the control group(25.26%), and 9 cases in the observation group(9.38%). The incidence of peritonitis in the observation group was lower than that in the control group, and the difference was statistically significant(χ 2=5.972, P<0.05). Conclusion:The occurrence of peritoneal dialysis-related peritonitis is related to a variety of factors.Paying attention to the routine examination of peritonitis and observing the color of peritonitis, strengthening the aseptic fluid exchange operation, and following up the patients can effectively reduce the occurrence of peritonitis and improve the quality of dialysis.
