Objective To observe the effect of intelligent flexible ankle stretching training on lower extremity spasm in patients with spinal cord injury. Methods From June,2021 to May,2024,28 patients with spinal cord injury were randomly divided into control group(n=14)and experimental group(n=14).Both groups received conventional rehabilitation treatment.On this ba-sis,the control group received manual extension treatment,and the experimental group received intelligent flexi-ble ankle stretching system training,for eight weeks.The modified Ashworth Scale(MAS),ankle dorsiflexion an-gle,Clinical Spasticity Index(CSI),max root mean square(RMSmax)of surface electromyography of gastrocne-mius medial head and vibration perception threshold(VPT)of great toe were compared. Results After treatment,MAS(χ2=10.378,P=0.035),ankle dorsiflexion angle(Z=-3.306,P<0.001),CSI(t=4.101,P=0.001)and RMSmax of gastrocnemius medial head(Z=-3.296,P<0.001)improved in the experimental group,while MAS(χ2=11.418,P=0.022),ankle dorsiflexion angle(Z=-1.986,P=0.047)and RMSmax of gas-trocnemius medial head(Z=-2.297,P=0.021)were better in the experimental group than in the control group.Although VPT was improved after treatment,no significant difference was found within and beteen groups(P>0.05). Conclusion The intelligent flexible ankle stretching training could improve the lower limb muscle spasticity in patients with spinal cord injury,and may be benefit for foot proprioception.

Objective:To examine the factors that contribute to memory impairment in elderly stroke patients and develop a predictive model.Methods:One hundred stroke patients from the First People's Hospital of Changzhou were selected to assess the incidence of memory impairment using the Montreal cognitive assessment memory index score(MoCA-MIS).Univariate analysis and multivariate Logistic regression were performed to determine the factors influencing memory impairment in these patients.Additionally, the correlation among relevant scale scores was examined, and a prediction model was developed.Results:In the study, 49 patients(49.0%)did not exhibit memory impairment.Patients with memory impairment were found to have higher proportions of individuals over 75 years old, elevated levels of triglyceride(TG), total cholesterol(TC), low-density lipoproteins cholesterol(LDL-C), and National Institute of Health Stroke Scale(NIHSS)scores compared to those without memory impairment.Conversely, patients without memory impairment had higher proportions of individuals with more than 9 years of education, higher levels of high-density lipoprotein cholesterol(HDL-C), mini-mental state examination(MMSE)scores, Rivermead behavioural memory test-Ⅱ(RBMT-Ⅱ)scores, and picture-based memory impairment screen(PMIS)scores(all P<0.05).Furthermore, Montreal cognitive assessment-memory index(MoCA-MIS)scores in stroke patients with memory impairment showed negative correlations with NIHSS scores, TG, and LDL-C, while showing positive correlations with HDL-C, MMSE scores, RBMT-Ⅱ scores, and PMIS scores(all P<0.05).Multifactorial Logistic regression analysis indicated that years of education, TG, HDL-C, NIHSS score, MMSE score, RBMT-Ⅱ score, PMIS score, and the location of the lesion in the cortex or temporal lobe were significant factors influencing memory impairment in stroke patients(all P<0.05).The receiver operating characteristic curve(ROC)analysis revealed an area under curve(AUC)of 0.955(95% CI: 0.921-0.977)for the prediction model of memory impairment in stroke patients, with a Yoden index of 0.841. Conclusions:The risk of memory impairment in stroke patients is associated with education years and blood lipid levels.Factors such as high education level, active cognitive function, and memory training serve as protective factors against memory impairment.The prediction model developed using these influencing factors demonstrates high predictive accuracy for post-stroke memory impairment.

Objective To explore the mechanism of Zhuangxuan Yin in the treatment of children with H1N1 pneumonia through regulating gut microbiota mediated by p38 mitogen-activated protein kinase(p38-MAPK)pathway.Methods A BALB/c mouse model of H1N1 pneumonia was prepared using the H1N1 influenza virus allantoic solution for nasal drop.The model was randomly separated into 5 groups:model group,Zhuangxuan Yin low-,medium-and high-dose groups,and high-dose Zhuangxuan Yin(28.66 g·kg-1)+anisomycin(10 mg·kg-1)group.The control group was infused with sterile physiological saline of equal volume using the same method.After treatment with Zhuangxuan Yin and anisomycin,the lung index of mice in each group was measured,and HE staining was applied to detect the pathological morphology of lung and large intestine tissues.16SrRNA gene sequencing was applied to detect the structural difference of gut microbiota in mice of each group.Enzyme-linked immunosorbent assay(ELASA)was applied to measure the levels of tumor necrosis factor-α(TNF-α),interleukin(IL)-4,IL-6,and IL-1β in bronchoalveolar lavage fluid(BALF)and large intestine tissue of mice in each group.Western Blot was applied to detect the expression of p38-MAPK pathway-related proteins in lung and large intestine tissues of mice in each group.Results Compared with the control group,the lung and large intestine tissues of the model group mice showed obvious pathological damage,the lung index,pathological score of lung and large intestine,ACE index,Shannon index,abundance of class Clostridia,the levels of TNF-α,IL-4,IL-6,and IL-1β in BALF and large intestine tissues,and p-p38-MAPK/p38-MAPK in lung and large intestine tissues increased(P＜0.05).The abundance of class Bacteroidales decreased(P＜0.05).Compared with the model group,the pathological damage in the lung and large intestine tissues of mice in the Zhuangxuan Yin low-,medium-and high-dose groups were reduced.The lung index,pathological score of lung and large intestine,ACE index,Shannon index,abundance of class Clostridia,the levels of TNF-α,IL-4,IL-6,and IL-1β in BALF and large intestine tissues,and p-p38-MAPK/p38-MAPK in lung and large intestine tissues decreased(P＜0.05),the abundance of class Bacteroidales increased(P＜0.05),and in a dose-dependent manner(P＜0.05).Compared with the high-dose Zhuangxuan Yin group,the pathological damage in the lung and large intestine tissues of mice in the high-dose Zhuangxuan Yin+anisomycin group was aggravated,the lung index,pathological score of lung and large intestine,ACE index,Shannon index,abundance of class Clostridia,the levels of TNF-α,IL-4,IL-6,and IL-1β in BALF and large intestine tissues,and p-p38-MAPK/p38-MAPK in lung and large intestine tissues increased(P＜0.05),and the abundance of class Bacteroidales decreased(P＜0.05).Conclusion Zhuangxuan Yin can improve the imbalance of intestinal microbiota in H1N1 pneumonia mice by inhibiting p38-MAPK signal activation,thereby inhibiting inflammation and reducing lung and large intestine tissue damage in mice,which may have a therapeutic effect on children with H1N1 pneumonia.

Objective:To document any correlation between eye-tracking test results and cognitive impairment after a stroke.Methods:Forty stroke survivors made up the stroke group, while 20 healthy subjects without a history of stroke formed the normal group. Everyone was given an eye-tracking test, the mini-mental state examination (MMSE), and the Montreal Cognitive Assessment (MoCA). The eye-tracking test results were then tested for any correlation with age, level of education, and the MMSE and MoCA scores.Results:In the static image test and the prosaccade test, the total number of fixations was significantly higher in the stroke group than in the normal group. In the dynamic path test, the ocular motor test and the anti-saccade test, significant differences were observed between the two groups in terms of the duration of total fixation, the fixation duration ratio, and the total number of fixations. In the static image test, the total number of fixations was weakly negatively correlated with the MMSE scores. Total fixation duration and fixation duration ratio were weakly positively correlated with the MoCA scores, while total number of fixations, total saccade distance and average saccade velocity were weakly negatively correlated with the MoCA scores. In the dynamic path test, total fixation duration was weakly positively correlated with the MMSE and MoCA scores. Fixation duration ratio was weakly positively correlated with the MMSE scores and weakly negatively correlated with the MoCA scores. First fixation duration was weakly positively correlated with the MoCA scores. The total number of fixations was weakly positively correlated with age and weakly negatively correlated with the MoCA scores. Total saccade distance was weakly negatively correlated with age and the MoCA scores, and average saccade velocity was weakly negatively correlated with the MMSE and MoCA scores. In the ocular motor test, total fixation duration and fixation duration ratio were weakly positively correlated with the MoCA scores. Total number of fixations, total saccade distance, and average saccade velocity were weakly negatively correlated with the MoCA scores. In the prosaccade test, total fixation duration and fixation duration ratio were weakly positively correlated with the MoCA scores. Total number of fixations was weakly positively correlated with age and weakly negatively correlated with the MoCA scores. Total saccade distance and average saccade velocity were weakly negatively correlated with both the MMSE and MoCA scores. In the anti-saccade test, total fixation duration was weakly and positively correlated with age and the MoCA scores. Fixation duration ratio was weakly and positively correlated with age and the MoCA scores. The total number of fixations was weakly positively correlated with age and weakly negatively correlated with the MoCA scores, and total saccade distance and average saccade velocity were weakly negatively correlated with the MoCA scores.Conclusions:Eye-tracking test results are significantly correlated with post-stroke cognitive impairment, suggesting that such tests can be used in the assessment of post-stroke cognitive dysfunction.

Objective To explore the application effect of air bag compression combined with multi-step automatic decompression in radial artery hemostasis after coronary angiography in elderly patients. Methods A total of 630 elderly patients who underwent transradial coronary angiography in our hospital from March 2023 to April 2024 were selected as study subjects and randomly divided into control group, observation group 1, and observation group 2, with 210 patients in each group. The control group received manual compression hemostasis with a three-step air bag compressor after surgery, while the observation group 1 and observation group 2 received automatic compression hemostasis with a customized pressure step compressor for three-step and five-step compression, respectively, on the air bag compressor after surgery. The bleeding rate, delayed pressure release rate, radial artery stenosis rate, radial artery occlusion rate, and nursing work time were compared among the three groups after surgery (after CAG and before removal of the air bag compressor). Pain scores, heart rate, and blood pressure were recorded after surgery and before pressure release at 1 h after surgery. Results The observation group 2 had better results in bleeding rates, delayed pressure release rates, radial artery stenosis rates, and occlusion rates at the puncture site compared with the control group and observation group 1(P < 0.05). The nursing work time in the observation group 1 and observation group 2 was shorter than that in the control group (P < 0.05). The pain scores, heart rate, and systolic blood pressures before pressure release at 1 h after surgery were better in all three groups compared with those after surgery (P < 0.05). The pain scores, heart rates, and blood pressures before pressure release at 1 h after surgery in the observation group 2 were better than those in the control group and observation group 1 (P < 0.05). Conclusion The application of air bag compression combined with a five-step gradual automatic decompression method for compression hemostasis can effectively reduce the incidence of radial artery complications, shorten nursing work time, and improve patients' comfort.

BACKGROUND: Hepatitis B surface antigen (HBsAg) clearance is vital for a functional cure of hepatitis B virus (HBV) infection. However, the incidence and predictors of HBsAg seroclearance in patients co-infected with HBV and human immunodeficiency virus (HIV) remain largely unknown in Guangdong, China. METHODS: Between 2009 and 2019, patients co-infected with HBV/HIV undergoing antiretroviral therapy (ART) in Guangzhou Eighth People's Hospital affiliated to Guangzhou Medical University were retrospectively reviewed with the endpoint on December 31, 2020. The incidence and risk factors for HBsAg seroclearance were evaluated using Kaplan-Meier and multivariate Cox regression analyses. RESULTS: A total of 1550 HBV/HIV co-infected patients were included in the study, with the median age of 42 years and 86.0% (1333/1550) males. Further, 98.3% (1524/1550) received ART containing tenofovir disoproxil fumarate (TDF) plus lamivudine (3TC). HBV DNA was examined in 1283 cases at the last follow-up. Over the median 4.7 years of follow-up, 8.1% (126/1550) patients achieved HBsAg seroclearance, among whom 50.8% (64/126) obtained hepatitis B surface antibody, 28.1% (137/488) acquired hepatitis B e antigen seroconversion, and 95.9% (1231/1283) undetectable HBV DNA. Compared with patients who maintained HBsAg positive, cases achieving HBsAg seroclearance showed no differences in age, gender, CD4 + T cell count, alanine aminotransferase (ALT) level, or fibrosis status; however, they presented lower HBV DNA levels, lower HBsAg levels, and higher rates of HBV genotype B at the baseline. Multivariate analysis showed that baseline HBsAg <1500 cutoff index (COI) (adjusted hazard ratio [aHR], 2.74, 95% confidence interval [95% CI]: 1.48-5.09), ALT elevation >2 × upper limit of normal during the first six months after receiving ART (aHR, 2.96, 95% CI: 1.53-5.77), and HBV genotype B (aHR, 3.73, 95% CI: 1.46-9.59) were independent predictors for HBsAg seroclearance (all P <0.01). CONCLUSIONS Long-term TDF-containing ART has high anti-HBV efficacy including relatively high overall HBsAg seroclearance in HBV/HIV co-infected patients. Lower baseline HBsAg levels, HBV genotype B, and elevated ALT levels during the first six months of ART are potential predictors of HBsAg seroclearance.

Objective:To explore the current status of surgery for portal hypertension to grasp current status and future development of surgery in China.Methods:This study is jointly sponsored by China Hepatobiliary & Pancreatic Specialist Alliance & Portal Hypertension Alliance in China (CHESS).Comprehensive surveying is conducted for basic domestic situations of surgery for portal hypertension, including case load, surgical approaches, management of postoperative complications, primary effects, existing confusion and obstacles, liver transplantation(LT), laparoscopic procedures and transjugular intrahepatic portosystemic shunt(TIPS), etc.Results:A total of 8 512 cases of portal hypertension surgery are performed at 378 hospitals nationwide in 2021.Splenectomy plus devascularization predominated(53.0%)and laparoscopy accounted for 76.1%.Primary goal is preventing rebleeding(67.0%) and 72.8% of hospitals used preventive anticoagulants after conventional surgery.And 80.7% of teams believe that the formation of postoperative portal vein thrombosis is a surgical dilemma and 65.3% of hospitals practiced both laparoscopy and TIPS.The major reasons for patients with portal hypertension not receiving LT are due to a lack of qualifications for LT(69.3%)and economic factors(69.0%).Conclusions:Surgery is an integral part of management of portal hypertension in China.However, it is imperative to further standardize the grasp of surgical indications, the handling of surgical operation and the management of postoperative complications.Moreover, prospective, multi-center randomized controlled clinical studies should be performed.

Objective:To explore vibration, position and motion proprioception of the ankle joints after a stroke.Methods:Twenty-eight stroke survivors with impaired ankle proprioception were divided into a right-side stroke group ( n=18) and a left-side stroke group ( n=8). Twenty-two healthy volunteers constituted a control group. Vibration perception thresholds, passive and active joint angle resetting, and motion minimum thresholds were quantified among the stroke survivors on both the healthy and the affected side. With the controls the dominant and non-dominant sides were used. The differences in proprioception between the healthy volunteers and the stroke patients, between the affected side and the healthy side of the stroke patients, and between left- and right-side stroke patients were analyzed and compared. Results:Among the stroke survivors the vibration perception threshold on the affected side averaged (28.91±22.53)μm. The absolute difference in the perception of passive positioning was (5.49±5.39)° for 15° of plantar flexion and (4.48±3.89)° for 5° of dorsal extension. In active positioning plantar flexion was (5.23±4.34)° and for 30° of plantar flexion it was (3.26±1.73)°. The 5° dorsal extension error was (4.97±3.48)°. The motion perception thresholds between 20° of plantar flexion, 10° of plantar flexion and the neutral position were significantly higher, on average, than among the control group. The stroke group also had significantly higher motion perception thresholds than the control group.Conclusion:The vibration, position, and motion sense of the ankle joint on a stroke survivor′s affected side tend to be impaired, with the impairment of vibration and motion sensing tend to be more substantial. After stroke, there is also mild impairment of vibration, position and motion sensing in the healthy ankle joint. The impairment of proprioception caused by right cerebral hemisphere injury may be more serious than that caused by injury on the left.

Objective:To explore the application effect of continuous nursing based on hybrid electronic platform and fragmentation time in the out-of-hospital rehabilitation of patients with anterior cruciate ligament reconstruction.Methods:This was a randomized controlled study. From April 2020 to October 2021, a total of 90 patients undergoing anterior cruciate ligament reconstruction in Weifang People′s Hospital were selected as the research objects by convenience sampling. Forty patients from April to December 2020 were selected as control group, and 45 patients from January to October 2021 were selected as intervention group. The control group implemented routine discharge guidance and follow-up, while the intervention group was given continuous nursing plan based on the concept of hybrid electronic platform and fragmented time. Before operation and 1, 3 and 6 months after operation, the knee range of motion and Lysholm score of patients in the two groups were analyzed. At 1, 3 and 6 months after operation, the rehabilitation exercise compliance score, self-efficacy score and knee stability examination of the two groups were analyzed.Results:A total of 41 patients in each group completed the study. At 1 month after operation, the knee range of motion, Lysholm score, rehabilitation exercise compliance score and self-efficacy score of intervention group were (96.46 ±3.58) ° and (53.54 ± 6.57), (69.17 ± 6.27), (4.01 ± 0.38) points, respectively. In the control group, they were (89.02 ± 4.22)° and (45.02 ± 7.61), (56.78 ± 8.45), (3.61 ± 0.42) points. At 3 months after operation, they were (136.83 ± 4.30)° and (72.76 ± 4.96), (60.71 ± 5.87), (4.97 ± 0.32) points in the intervention group, (133.54 ± 3.58)° and (69.83 ± 6.65), (56.73 ± 8.57), (4.83 ± 0.45) points in the control group, respectively. At 6 months after operation, they were (139.39 ± 1.99)° and (85.61 ± 6.11), (57.71 ± 7.41), (6.58 ± 0.96) points in the intervention group, (138.29 ± 2.65)° and (81.80 ± 6.38), (47.90 ± 6.02), (6.35 ± 1.23) points in the control group, respectively. The knee range of motion, Lysholm score and rehabilitation exercise compliance score of the intervention group were better than those of the control group at 1, 3 and 6 months after operation, and the differences were statistically significant ( t values were 2.12-8.61, all P<0.05). The self-efficacy score of the intervention group was higher than that of the control group at 1 month after operation, and the difference was statistically significant ( t=4.57, P<0.05). Conclusions:The continuous nursing program based on hybrid electronic platform and fragmented time can improve the knee function of patients with anterior cruciate ligament reconstruction in the early postoperative period, improve the compliance of rehabilitation exercise and the level of early self-efficacy.
