Objective: To analyze the etiological surveillance results of influenza-like illness (ILI) cases in Jiangsu Province, and investigate the distribution characteristics of different influenza virus types, so as to provide the evidence for improving influenza prevention and control measures. Methods: Influenza laboratory testing data for sentinel surveillance of ILI cases in Jiangsu Province from 2019 to 2024 were collected through the China Influenza Surveillance Information System. The positive detection rate of influenza virus was calculated, and descriptive analysis was performed to characterize the distribution of different influenza virus types. Using the farthest neighbor linkage method, influenza virus positive detection rates clustering was analyzed by year and week. Clusters were defined based on inter-cluster distance, and the intensity of the positive detection rate was visualized through color gradients in the clustering heatmap. Results: From 2019 to 2024, a total of 183 878 ILI specimens were collected in Jiangsu Province. Among them, 20 059 specimens tested positive for influenza virus, corresponding to an overall positive detection rate of 10.91%, and an average annual positive detection rate of 10.89%. The primary circulating influenza virus types were influenza A H3N2 subtype, accounting for 40.92%, followed by influenza B Victoria linage at 34.00%, and influenza A H1N1 subtype at 24.80%. Influenza B Yamagata linage was not detected throughout the five-year period. Influenza A H3N2 subtype predominated during two distinct periods: from January to March 2019, and from June 2022 to December 2023. Influenz B Victoria linage was the dominant type from April 2019 to May 2022 and again from January to April 2024. Influenza A H1N1 subtype emerged as the primary type from May to December 2024. Year-based clustering analysis grouped the annual positive detection rates from 2019 to 2024 into three clusters. The closest cluster distance was observed between 2019 and 2024. The highest annual positive detection rate occurred in 2023. Both influenza A H3N2 and H1N1 subtype each formed a single cluster, with their peak positive detection rates also recorded in 2023. Influenza B Victoria lineage was separated into two clusters, with its highest positive detection rate occurring in 2020. Week-based clustering analysis revealed that influenza virus detection was concentrated in weeks 47 to 52 and weeks 1 to 15. More specifically, the positive detection rates for influenza A H3N2 subtype peaked during weeks 30 to 34 and weeks 42 to 52; for influenza A H1N1 subtype, during weeks 9 to 15 and weeks 51 to 52; and for influenza B Victoria lineage, during weeks 1 to 11 and weeks 50 to 52. Conclusions From 2019 to 2024, the average annual positive detection rate of influenza virus in Jiangsu Province remained relatively low. Influenza activity characterized by the alternating circulation of influenza A H1N1 subtype, influenza A H3N2 subtype, and influenza B Victoria linage. It is necessary to maintain the surveillance sensitivity for the influenza B Yamagata lineage.

Objective:To explore the clinical efficacy of Kinesio taping combined with extracorporeal shock wave and the plantar pressure evaluation in the treatment of plantar fasciitis. Method:A total of 67 patients with unilateral plantar fasciitis were randomly divided into the control group(ESWT group)and the experimental group(KT combined group).The patients in the two groups were given the same health education and extracorporeal shock wave treatment(ESWT),and the experimental group was treated with Kinesio taping(KT).The pain and functional activity were evaluated by pain visual analogue scale and AOFAS ankle and hind-foot function scale;The insole plantar pressure measuring system was used to mea-sure the peak pressure values of each plantar regions.The clinical efficacy and plantar pressure of the affected side were compared before treatment,the 3rd week of treatment and 5th week of treatment. Result:There was no significant difference in various indcators of the measurements between the two groups before treatment(P＞0.05).The score of pain rating,functional activity scale score and plantar pressure of pa-tients in both groups were significantly improved at the 3rd week and the 5th week of treatment(P＜0.05),com-pared with those before treatment.At the 3rd week of treatment,there was no significant difference between the two groups in pain degree and functional activity scale score(P＞0.05),but there was statistical difference in plantar pressure analysis(P＜0.05).The peak force weight ratio of the medial heel in the KT combined group was significantly greater than that in the control group.At the 5th week of treatment,there were statisti-cally significant differences between the two groups in the score of pain rating,functional activity scale score and plantar pressure(P＜0.05).The KT combined treatment group was significantly better than the control group in the pain improvement and functional activity,and the weight bearing of the middle foot and hind foot was also significantly higher than the control group. Conclusion:Compared with the simple extracorporeal shock wave therapy,the combination of KT therapy can better relieve pain,improve the function of hind foot,correct abnormal foot weight bearing,and improve the gait of patients.

BACKGROUND:Kinesio taping is often used for the treatment of various sports injuries.The methods of foot and ankle sports taping are complex and diverse.Among them,Fascia taping is applicable to a wider range of people and can be used for different foot posture types,but it still lacks of practical verification,and its specific biomechanical role is not clear. OBJECTIVE:To observe the changes in plantar pressure characteristics of subjects with different foot positions during walking and jogging after Fascia taping. METHODS:Thirty-seven young healthy subjects were recruited from the Yantai campus of Binzhou Medical University to conduct the test.They were scored according to the foot posture index-six items version,and were divided into the supination foot group,the neutral foot group,and the pronation foot group.The static foot morphological indexes(including navicular drop,arch height index,arch height flexibility-longitudinal arch,and arch height flexibility-transverse arch)and the pressure-time integral of each foot zone during walking and jogging were collected and calculated respectively before and after Kinesio taping.The specific biomechanical mechanism of Fascia taping was analyzed. RESULTS AND CONCLUSION:(1)General data:There was no statistical difference among the three groups of subjects in general data,such as gender,height,and body mass index(P>0.05).Before taping,there was a significant difference in the foot morphological indexes and the areas of the outer front foot,midfoot,and hindfoot between different foot posture groups(P<0.01).(2)Static foot morphological indexes:After taping,there was no statistically significant difference between the groups in navicular drop,arch height flexibility-longitudinal arch,and arch height flexibility-transverse arch(P>0.05),while there was still a significant difference between the groups in the arch height index(P<0.05).In the supination foot group,the arch height index increased slightly,but there was no significant difference before and after taping(P>0.05).In the pronation foot group,the navicular drop and arch height flexibility-longitudinal arch was significantly reduced,and the arch height index was increased.There was a significant difference before and after taping(P<0.05).(3)The index of plantar pressure during walking:After taping,there was no significant difference between the three groups in the area of lateral forefoot and medial midfoot(P>0.05).In the pronation foot group,the lateral load of the forefoot increased after taping(P<0.05).In the supination position group,the load of the lateral forefoot and midfoot regions increased significantly(P<0.05),while the difference in the rear foot region was not significant(P>0.05).(4)The index of plantar pressure during jogging:After taping,there was no statistically significant difference between groups in the lateral forefoot(P>0.05).In the pronation foot group,the load of the medial forefoot increased significantly(P<0.05).In the supination position group,the load of the lateral forefoot,the middle foot and the rear foot region increased significantly(P<0.05).(5)The results showed that the Fascia taping was suitable for different foot postures.It could not only correct the static foot structure of subjects with different foot postures,but also regulate the abnormal plantar pressure distribution during the dynamic activities of walking and jogging,and the load of the midfoot,forefoot,and hindfoot in the supination and pronation posture tended to normal foot posture load level.

Objective:To explore the clinical characteristics and risk factors of sarcopenia in elderly patients with chronic kidney disease (CKD) stage 3-4.Methods:It was a single-center, retrospective observational study. CKD stage 3-4 patients aged ≥60 years old from March 2019 to March 2022 in the Geriatrics Department of the First Affiliated Hospital of Zhengzhou University were enrolled in the study. General data of the patients were collected, and laboratory indicators, muscle strength, physical function and appendicular muscle mass index (ASMI) were measured. According to the diagnostic criteria of sarcopenia, the patients were divided into no sarcopenia CKD group and sarcopenia CKD group. Baseline data between these two groups were compared. Logistic regression analysis was used to analyze the related factors of sarcopenia in elderly CKD stage 3-4 patients.Results:A total of 162 CKD stage 3-4 patients were enrolled in this study, with 89 males (54.9%) and a median age of 75 (69, 82) years. Sarcopenia was diagnosed in 40 cases, and the prevalence was 24.7% (95% CI 18.1%-31.3%). Compared with no sarcopenia CKD group, age, proportion of dementia, cystatin C, urea nitrogen, C-reactive protein (CRP) and ratio of urine protein to creatinine were higher (all P<0.05), while body mass index (BMI), hemoglobin, carbon dioxide combining power, estimated glomerular filtration rate (eGFR), serum albumin and the proportion of regular exercise and using α-ketones were lower in sarcopenia CKD group (all P<0.05). Meanwhile, grip strength, walking speed, short physical performance battery score and ASMI were lower in sarcopenia CKD group (all P<0.05). Multivariable logistic regression analysis results showed that low eGFR ( OR=0.824, 95% CI 0.687-0.987, P=0.036), low BMI ( OR=0.463, 95% CI 0.304-0.704, P<0.001), low serum albumin ( OR=0.459, 95% CI 0.263-0.802, P=0.006) and high CRP ( OR=2.754, 95% CI 1.708-4.439, P<0.001) were the independent related factors of sarcopenia in elderly CKD patients. Conclusions:The prevalence of sarcopenia in elderly CKD stage 3-4 patients is high. Low eGFR, low BMI, low serum albumin and high CRP are the independent risk factors for sarcopenia in elderly CKD stage 3-4 patients.

ObjectiveTo explore the effect of core stability training on dynamic balance and surface electromyography (sEMG) after anterior cruciate ligament reconstruction (ACLR), and to analyze the correlation between balance index and sEMG. MethodsFrom March to December, 2022, 32 patients with ACLR in Yantai Affiliated Hospital of Binzhou Medical University were randomly divided into control group (n = 16) and experimental group (n = 16). The control group accepted routine rehabilitation treatment, and the experimental group added core stability training, for six weeks. They were evaluated with American Hospital for Special Surgery Knee Score (HSS) and International Knee Documentation Committee Knee Score (IKDC), and the dynamic balance function and sEMG were measured before and after treatment, and the correlation between dynamic balance index and root mean square (RMS) of sEMG was analyzed. ResultsAfter treatment, the scores of HSS and IKDC increased significantly in both groups (|Z| > 3.526, |t| > 63.544, P < 0.001), and were better in the experimental group than in the control group (Z = -2.392, t = 2.650, P < 0.05); the length of gait line and single support line increased significantly, the medial-lateral displacement displacement decreased (|t| > 2.368, Z = -3.516, P < 0.05), and they were better in the experimental group than in the control group (|t| > 2.497, Z = -3.091, P < 0.05); the RMS of gluteus maximus and gluteus medius increased in the experimental group (t = -5.900, Z = -2.741, P < 0.01), and were better than those in the control group (t = 3.930, Z = -3.260, P < 0.01). After treatment, the RMS of gluteus maximus and gluteus medius in both groups were positively correlated with gait line length and single support line length, and were negatively correlated with medial-lateral displacement (|r| > 0.502, P < 0.01). ConclusionCore stability training could significantly improve knee joint function and dynamic balance, and enhance the activation of gluteus maximus and gluteus medius. Dynamic balance is highly correlated with sEMG.

Objective:To investigate the effect of improving moderate and severe benign prostatic hyperplasia(BPH)with lower urinary tract symptoms(LUTS)on renal function in elderly patients aged 80 years and over.Methods:A total of 129 inpatients with moderate and severe BPH and its associated LUTS(BPH/LUTS)who took tamsulosin combined with finasteride aged 80 years old and over in Geriatric Department of the First Affiliated Hospital of Zhengzhou University were enrolled in the retrospective study from July 2018 to July 2020.Patients were divided into normal blood pressure group(n=51)and hypertension group(n=78)and divided into normal renal function group(n=77)and CKD3a stage group(n=52).Serum creatinine, estimated glomerular filtration rate(eGFR), prostate volume(PV)and post-void residual urine volume(PVR), and International Prostate Symptom Score(IPSS)were compared before versus after 1, 3 and 6 months of treatment.Multivariable linear regression analysis was performed to evaluate the influence of the most relevant factors on renal function in patients with BPH/LUTS.Results:After 1, 3 and 6 months of tamsulosin combined with finastide treatment, the lower urinary tract symptoms of elderly patients with BPH/LUTS were improved, IPSS score and PVR were decreased, and the differences were statistically significant(all P<0.01).PV, serum creatinine and eGFR were not changed after 6 months of treatment(all P>0.05).However, further subgroup analysis showed that serum creatinine level in hypertension group and CKD3a stage group was increased compared with that before treatment, while eGFR in CKD3a stage group was decreased before treatment, and the difference was statistically significant(all P<0.05).Compared with before treatment, serum creatinine and eGFR in hypertensive group improved after 3 months of treatment, and CKD3a group improved after 1 month of treatment, and the differences were statistically significant(all P<0.05).There were no significant changes in serum creatinine and eGFR in normal blood pressure group and normal renal function group after 6 months of treatment(all P>0.05).Multiple linear regression analysis showed that hypertension( β=2.06, P<0.05)and CKD3a stage( β=17.16, P<0.01)were independent risk factors for creatinine changes before and after treatment.Hypertension( β=-2.27, P<0.01), CKD3a stage( β=-11.93, P<0.01)and CKD3A stage( β=-2.27, P<0.01)were independent risk factors for creatinine changes before and after treatment. P<0.01)and PV before treatment( β=-0.11, P<0.05)were independent risk factors for the change of eGFR before and after treatment. Conclusions:Treatment for moderate and severe BPH/LUTS can improve renal function in elderly patients with hypertension or CKD3a.

Objective:To investigate the mechanism of subjective cognitive decline(SCD)in resting-state by using regional homogeneity(ReHo)and functional connectivity(FC)in SCD patients.Methods:Resting-state functional magnetic resonance imaging(RS-fMRI)was performed in 25 SCD patients and 30 normal controls matched by sex, education and nationality.DPARSFA2.3 and SPM8 software were used to analyze and screen the brain areas with abnormal ReHo values in SCD group, with the posterior cingulated(PCC)/paruneus as seed points for whole-brain FC analysis.Results:Compared with the normal control group, the SCD group showed that ReHo values of right occipital gyrus and left precuneus were increased, and ReHo values of right inferior temporal gyrus, right orbital inferior frontal gyrus and bilateral thalamus were decreased(Voxel level, Alphasim correction, P<0.05). Using PCC/ precuneus as seed voxels, the whole brain functional connectivity analysis showed that the functional connectivity with cerebelum Crus 2 R was increased, and the functional connectivity with right orbital inferior frontal gyrus, left inferior temporal gyrus and temporal pole was reduced(Voxel level, Alphasim correction, all P<0.05). Conclusions:Default mode network may play an important role in the mechanism of SCD, and abnormalities in brain areas may first occur in PCC/precuneus.

Objective:To investigate regional homogeneity(ReHo)and whole brain functional connectivity(FC)in patients with mild cognitive impairment(MCI), and to explore the mechanisms of MCI in the resting state.Methods:Resting-state functional magnetic resonance imaging(RS-fMRI)was performed on 24 patients with MCI and 30 age, gender and nationality-matched normal controls.Abnormal brain areas in the MCI group were screened and analyzed by using the DPARSFA2.3 and SPM8 software programs.Whole brain FC analysis was performed with the posterior cingulate cortex(PCC)/precuneus as the seed points.Results:Compared with the control group, MCI subjects displayed higher ReHo values in the frontal-middle-Left, precentral-Left, postcentral-Left, rolandic-opercular-Left, and frontal-inferior-opercular-Left and lower ReHo values in the temporal-superior-right, temporal-middle-right, postcentral-right, and temporal -pole -superior -right(Voxel level, Alphasim correction, P<0.05). Whole brain FC analysis showed greater functional connectivity of PCC/precuneus with fusiform-right, thalamus-right, lingual-right and parahippocampal-right in subjects with MCI, and less functional connectivity of the PCC/precuneus with temporal-middle-Left, angular-Left, temporal-superior-Left and occipital-middle-Left in subjects with MCI(Voxel level, Alphasim correction, P<0.05). Conclusions:Abnormalities of the default mode network may be associated with the onset of MCI, and abnormalities in posterior cingulate/precuneus connectivity may be helpful in finding imaging evidence with high sensitivity to MCI.
