Objective:To observe the effect of robot-assisted upper-limb training on motor function in stroke patients with hemiplegia,utilizing ultrasound shear wave elastography(SWE)for quantitative assessment of muscle fiber pa-rameters,and to explore the application value of SWE in evaluating stroke rehabilitation outcomes.Method:Sixty-one stroke patients with upper-limb dysfunction admitted to the Department of Rehabilitation Medicine,People's Hospital of Xinjiang Uygur Autonomous Region between August 2024 and February 2025 were randomly assigned to a control group(n=31)or an experimental group(n=30)using a random number table.The control group received conventional rehabilitation training(60 minutes/session,once daily,7 ses-sions/week for 3 weeks).The experimental group received conventional training(40 minutes)plus upper limb robot-assisted training(20 minutes),with the same frequency and duration.Both groups were assessed before and after treatment using the Brunnstrom recovery stage(BRS)for motor staging,Fugl-Meyer Assessment for Upper Extremity(FMA-UE),modified Ashworth scale(MAS),and modified Barthel index(MBI).SWE was used to measure quantitative muscle fiber parameters.Result:After treatment,both groups showed statistically significant improvements in FMA-UE and MBI scores compared to baseline(P<0.05),with significantly greater improvement in the experimental group(P<0.05).BRS scores improved significantly within the experimental group(P<0.05)but showed no significant be-tween-group difference(P>0.05).MAS scores showed no significant within-or between-group differences(P>0.05).The shear modulus(G-value)of the middle deltoid,biceps brachii,and brachioradialis(in both relaxed and stretched states)improved significantly in the experimental group compared with the control group(P<0.05).The experimental group also showed a significant increase in the triceps brachii G-value in the relaxed state compared with both baseline and the control group(P<0.05).Significant within-group improvements(P<0.05)were seen in the anterior deltoid(experimental group)and posterior deltoid(control group)in the re-laxed state,but no significant between-group differences existed(P>0.05).No significant within-or between-group differences were found in the G-value of the anterior deltoid(experimental),posterior deltoid(con-trol),or triceps brachii in the stretched state(P>0.05).Conclusion:Upper-limb rehabilitation robot-assisted training is superior to conventional rehabilitation training in improving upper-limb motor function and reducing flexor spasticity in stroke patients.SWE technology can be used in quantitatively assessing muscle structural parameters in stroke patients.

Fusobacterium nucleatum (F. nucleatum) is an early pathogenic colonizer in periodontitis, but the host response to infection with this pathogen remains unclear. In this study, we built an F. nucleatum infectious model with human periodontal ligament stem cells (PDLSCs) and showed that F. nucleatum could inhibit proliferation, and facilitate apoptosis, ferroptosis, and inflammatory cytokine production in a dose-dependent manner. The F. nucleatum adhesin FadA acted as a proinflammatory virulence factor and increased the expression of interleukin(IL)-1β, IL-6 and IL-8. Further study showed that FadA could bind with PEBP1 to activate the Raf1-MAPK and IKK-NF-κB signaling pathways. Time-course RNA-sequencing analyses showed the cascade of gene activation process in PDLSCs with increasing durations of F. nucleatum infection. NFκB1 and NFκB2 upregulated after 3 h of F. nucleatum-infection, and the inflammatory-related genes in the NF-κB signaling pathway were serially elevated with time. Using computational drug repositioning analysis, we predicted and validated that two potential drugs (piperlongumine and fisetin) could attenuate the negative effects of F. nucleatum-infection. Collectively, this study unveils the potential pathogenic mechanisms of F. nucleatum and the host inflammatory response at the early stage of F. nucleatum infection.

Objective:To observe the urinary iodine content (UIC), breast milk iodine content (BMIC) and milk iodine excretion of lactating rats under different iodine nutrition levels, and to explore the iodine metabolism of the lactating rats under different iodine nutrition levels.Methods:Forty female Wistar rats with body weight ranging from 70 to 120 g were divided into low iodine (LI) group, normal iodine (NI) group, hight iodineⅠ (HIⅠ) group and hight iodine Ⅱ (HIⅡ) group according to body weight by random number table method, with 10 rats in each group. The rats were fed low-iodine diet, and the iodine ion concentration of drinking water in each group was 0, 325, 18 700 and 37 450 μg/L. Twenty male rats were fed according to the feed method of NI group. After 8 weeks of intervention, the male and female rats were caged and mated in a ratio of 1 ∶ 2. Milk and 24 h urine were collected on the 7th, 14th and 21st days of lactation (L7, L14 and L21), and the amount of food and drinking water consumed were recorded. The 24 h milk excretion was calculated by acute lactation test. UIC and BMIC were determined by inductively coupled plasma mass spectrometry (ICP-MS).Results:The 24 h total iodine intake of lactating rats in LI, NI, HIⅠ and HIⅡ groups were (1.84 ± 0.51), (30.51 ± 6.79), (765.95 ± 317.41) and (1 654.26 ± 560.55) μg/d, respectively. The difference between groups was statistically significant ( P < 0.001). At L7, L14 and L21, there were statistically significant differences in UIC, BMIC and milk iodine excretion at the same lactation stages among different groups ( P < 0.001). In HIⅡ group, the difference of BMIC and milk iodine excretion at different lactation stages (L7, L14, and L21) were significantly signrficant ( P < 0.05). The 24 h milk iodine excretion of LI, NI, HIⅠ and HIⅡ groups was (1.23 ± 0.85), (11.88 ± 5.23), (207.09 ± 114.51), (493.67 ± 242.47) μg, respectively. The proportion of 24 h milk iodine excretion to 24 h total iodine intake was 66.85%, 38.94%, 27.04% and 29.84%, respectively. Conclusions:About 39% of dietary iodine is supplied to offspring through milk when iodine nutrition is normal. The iodine excretion ratio of milk is increased or decreased with low and high iodine levels. These results indicate that lactating rats with different iodine nutrition levels can regulate the ratio of iodine excretion in milk through their own compensatory effect to reduce the influence of iodine deficiency and iodine excess on their offspring.

Objective:To investigate the effect of Asarinin on the survival time of transplanted heart after allogeneic heterotopic heart transplantation and to further verify the anti-immune rejection effect of Asarinin in spleen and peripheral blood.Methods:Using 64 Wistar rats as donors, 64 SD rats as recipients to establish the allogeneic heterotopic heart transplantation model in rats.After successful transplantation, 64 rats were use simple randomization divided into control group, cyclosporine A(CsA) group, Asarinin group and half CsA + half Asarinin group with 16 rats in each group.CsA group was given 5 mg/kg by gavage; Asarinin group was given 25 mg/kg; half dose group was given CsA 2.5 mg/kg+ Asarinin 12.5 mg/kg and the control group was given the same volume of normal saline by gavage.After administration for 1 week, half of them were used to observe the survival time.The other half of the rats were fully anesthetized with chloral hydrate, spleen and peripheral blood were taken.Half of the spleen was taken to observe the slices under the microscope.The other half of spleen was used RT-PCR to detect the relative expression of IFN-γ and IL-4.The expression of co-stimulatory molecules CD80, CD86 and CD40 in peripheral blood were detected by flow cytometry.Results:Survival time of transplanted heart was control group (8.4±0.9), CsA group (30.5±8.3), Asarinin group (16.5±4.3) and half-dose group (26.1±5.2) days.Compared with control group, survival time of heart transplantation became prolonged in all groups and the difference was statistically significant ( P<0.05). HE staining of splenic tissue showed that, as compared with control group, the injury of each group was alleviated.The relative expression of IFN-γ in spleen was control group (1.055±0.083), CsA group (0.396±0.038), Asarinin group (0.833±0.094) and half-dose group (0.862±0.104). The last three groups were lower than control group and the difference was statistically significant ( P<0.05). The relative expression of IL-4 in spleen was control group (1.429±0.234), CsA group (3.808±0.729), Asarinin group (2.209±0.306) and half-dose group (2.323±0.321). The last three groups all spiked as compared with control group and the difference was statistically significant ( P<0.05). The expressions of CD80, CD86 and CD40 in peripheral blood were control group (98.21±0.54), (85.78±0.89) and (96.36±0.66), CsA group (89.26±0.36), (56.86±2.32) and (88.11±1.61), Asarinin group (94.19±0.47), (79.01±1.12) and (87.86±1.67) and half-dose group (94.87±0.74), (80.81±0.98) and (89.71±0.97) respectively.The last three groups were lower than control group and the difference was statistically significant ( P<0.05). Conclusions:Asarinin can prolong the survival time of transplanted heart after allogeneic heterotopic heart transplantation in rats, inhibit the immune injury of spleen after allogeneic heterotopic heart transplantation in rats, decrease IFN-γ in spleen, increase IL-4 in spleen and inhibit the expression of peripheral blood costimulatory molecules CD80, CD86 and CD40.

Objective:To investigate the current application of colonoscopy at hospitals in China.Methods:From November 2019 to January 2020, an online questionnaire survey was conducted among gastroenterologists and colonoscopists in hospitals of different levels. The contents of questionnaire survey included basic information of colonoscopy at the respondent′s hospital, protocols and patient education of bowel preparation, implementation of colonoscopy quality control, and colonoscopists′ understanding of polypectomy techniques and post-polypectomy follow-up.Results:A total of 236 valid questionnaires were collected, involving 187 hospitals, and 143 (76.5%) had an annual operation capacity of more than 5 000 cases. In terms of bowel preparation, split-dosed polyethylene glycol electrolyte powder (PEG) was the most commonly used (60.4%, 113/187) and the most common volume of PEG was 3 L (67.4%, 126/187). Verbal (90.9%, 170/187) and written (79.7%, 149/187) instructions were given more often than other methods for patient education of bowel preparation. Antifoaming agent was routinely used in 124 (66.3%) hospitals. In terms of quality control, only 11.5% (20/174) hospitals implemented all four measures. In terms of polypectomy techniques, 98.1% (203/207) colonoscopists chose hot snare polypectomy or endoscopic mucosal resection for lesions of diameter>1 cm, while options varied for lesions of diameter<1 cm. The interval of follow-up after polypectomy recommended by colonoscopists was shorter than that by guidelines.Conclusion:Several problems are found in the survey in the application of colonoscopy in China, i. e., patient education of bowel preparation is not diversified; quality control of colonoscopy still needs to be strengthened; polypectomy techniques and follow-up after polypectomy need to be further standardized.

Objective:To summarize the progress and achievement of outpatient experience improvement in tertiary public hospitals from 2016 to 2021, so as to provide basis for further improving outpatient experience and raising outpatient satisfaction.Methods:Based on 5 round third-party evaluations of the China Healthcare Improvement Initiative from 2016 to 2021, descriptive trend analysis was conducted on the outpatient process and outpatient satisfaction, and stratified analysis was conducted on patient satisfaction in different regions and different types of institutions.Results:One hundred and thirty-six core sample hospitals were included in the 5 round evaluation, and 30 153 valid questionnaires were collected in the fifth evaluation in 2021.From 2016 to 2021, the overall satisfaction of outpatients in the 5 round evaluations was 91.4%, 87.3%, 90.1%, 91.1% and 95.4%, respectively. The satisfaction of outpatients to the medical services continued to improve. Outpatient treatment process has been continuously optimized, appointment registration has become the most commonly used way of outpatient registration. The satisfaction of outpatients to the process and environment of treatment in the western region was significantly improved.Conclusions:From 2016 to 2021, the overall satisfaction of outpatients has been consistently improved. Informatization helps to optimize the treatment process, but it is recommended that hospitals should provide special support for elderly outpatients.

Objective:To summarize the progress and achievement of inpatient experience improvement in public hospitals in China from 2016 to 2021, so as to provide basis for further improving hospitalization experience and raising inpatient satisfaction.Methods:Based on the five Third-party Evaluations of China Healthcare Improvement Initiative from 2016 to 2021, descriptive trend analysis was conducted on inpatient process, cost and inpatient satisfaction, and the inpatient satisfaction in different regions and different types of institutions was compared.Results:The overall satisfaction of hospitalized patients in the fifth evaluation in 2021(98.5%)was higher than that in the first evaluation in 2016(96.2%). The western region and maternal and child institutions had the most obvious improvement in the comparison of regional and institutional types. The improvement of inpatients′ satisfaction with diet was not obvious. Inpatients were most dissatisfied with " high medical expenses" , " cumbersome procedures" and " long waiting time for bed" .Conclusions:From 2016 to 2021, the satisfaction of hospitalized patients has been consistently improved, but there is still room for improvement in non-medical services. Hospital meals for inpatient and relief of inpatient healthcare financial burden are the priorities for healthcare improvement and raising hospitalization satisfaction in the next stage.

Objective:To construct a Nomogram model in predicting recurrence-free survival (RFS) and overall survival (OS) at six months, one year and two years after hepatocellular carcinoma (HCC) resection by using inflammatory markers combined with other routine clinical indicators.Methods:The data of 314 patients with HCC who underwent first time hepatectomy at Beijing Chaoyang Emergency Rescue Center and Air Force Characteristic Medical Center from January 2013 to January 2018 were analyzed. HCC patients who underwent hepatectomy at the First Medical Center of PLA General Hospital from January 2011 to January 2016 ( n=106) were used as the external validation group. Univariate and multivariate Cox proportional risk model was used to analyze independent risk factors of recurrence and death in HCC patients. A Nomogram model was constructed based on independent risk factors. Validation of the efficacy of the Nomogram model was done based on external data. Results:In the experimental group, 174 patients relapsed. The median RFS was 26 months. The 6 months, 1 year and 2 years RFS were 26.8%, 43.9%, and 68.8%, respectively. A total of 142 patients had died. The median survival time was 30 months. The 6 months, 1 year and 2 years OS were 5.9%, 23.6% and 63.1%, respectively. In the external validation group, 63 patients had developed recurrence, with a median RFS time of 28 months. The 6 months, 1 year and 2 years RFS were 26.4%, 45.3%, 54.7%, respectively. The median survival time was 31 months. The 6 months, 1 year and 2 years OS were 7.5%, 25.5%, 46.6%, respectively. Tumor size (>6.0 cm, HR: 1.447), vascular invasion ( HR: 1.408), TBil (>0.94 mg/dl, HR: 1.949), NLR (>2.54, HR: 2.843), AGR (≤0.88, HR: 2.447) were independent risk factors of HCC recurrence ( P<0.05). Tumor size (>6.0 cm, HR: 2.207), vascular invasion ( HR: 1.529), and NLR (>2.54, HR: 2.708) were independent risk factors of death for HCC patients ( P<0.05). The C-indexes of half-year, one-year and two-year RFS were 0.764 (95% CI: 0.677-0.854), 0.710 (95% CI: 0.615-0.824) and 0.673 (95% CI: 0.601-0.786), respectively. The C-indexes of half-year OS, one-year OS and two-year OS were 0.729 (95% CI: 0.648-0.841), 0.708 (95% CI: 0.608-0.813) and 0.664 (95% CI: 0.618-0.771), respectively. Conclusion:In this study, the construction of a Nomogram model in predicting prognosis of HCC patients was helpful to guide clinicians in improving preoperative treatment plans and in providing ideas for individualized treatment of patients.
