Objective: o develop an onset risk prediction nomogram for patients with homocysteine-type (H-type) hypertension (HTH) based on pulse diagram parameters to assist early clinical prediction and diagnosis of HTH. Methods: Patients diagnosed with essential hypertension and admitted to Shanghai Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai Hospital of Traditional Chinese Medicine, and Shanghai Hospital of Integrated Traditional Chinese and Western Medicine from July 6th 2020 to June 16th 2021, and from August 11th 2023 to January 22nd 2024, were enrolled in this retrospective research. The baselines and clinical biochemical indicators of patients were collected. The SMART-I TCM pulse instrument was applied to gather pulse diagram parameters. Multivariate logistic regression was adopted to analyze the risk factors for HTH. RStudio was employed to construct the nomogram model, receiver operating characteristic (ROC) curve, and calibration curve (bootstrap self-sampling 200 times), and clinical decision curve were drawn to evaluate the model’s discrimination and clinical effectiveness. Results: A total of 168 hospitalized patients with essential hypertension were selected and divided into non-HTH group (n = 29) and HTH group (n = 139). Compared with non-HTH group, HTH group had a lower body mass index (BMI), and higher proportions of male patients and drinkers (P < 0.05). The ventricular wall thickening (VWT) could not be determined. The proportions of left common carotid intima-media wall thickness (LCCIMWT) and serum creatinine (SCR) were higher in HTH group (P < 0.05). The pulse diagram parameter As was significantly higher, and H4/H1 and T1/T were lower in HTH group (P < 0.05). Gender, alcohol consumption, serum creatinine, and the pulse diagram parameter H4/H1 were identified as independent risk factors for HTH (P < 0.05). The nomogram’s area under the ROC curve (AUC) was 0.795 [95% confidence interval (CI): (0.706 6, 0.882 8)], with a specificity of 0.724 and sensitivity of 0.799. After 200 times repeated bootstrap self-samplings, the calibration curve showed that the simulated curve fits well with the actual curve (x2 = 9.5002, P = 0.301 9). The clinical decision curve indicated that the nomogram’s applicability was optimal when the threshold for predicting HTH was between 0.38 and 1.00. Conclusion The nomogram model could be valuable for predicting the onset risk of HTH and pulse diagram parameters can facilitate early screening and prevention of HTH.

Objective:To investigate the factors contributing to in-hospital mortality among elderly patients aged 80 and above with gastrointestinal bleeding(GIB).Additionally, it seeks to assess the predictive ability of the electronic frailty index(eFI)in determining the risk of in-hospital mortality in GIB patients.Methods:A retrospective analysis was performed among 624 patients aged 80 and above with GIB who were admitted to Beijing Hospital between July 2013 and September 2019.The patients were categorized into two groups based on their discharge outcomes: those who survived and those who did not.The eFI was developed using a cumulative deficit model utilizing data from the hospital's electronic medical records.The study examined the clinical features and risk factors associated with in-hospital mortality among these elderly patients.The effectiveness of eFI in predicting in-hospital mortality in elderly patients with gastrointestinal bleeding was evaluated by calculating the area under the curve(AUC)of the receiver operating characteristic(ROC)curve.Results:Among a total of 624 patients aged between 80 and 102 years, the average age was(83.0±6.4)years, with 339 being male.A majority of the patients, 581 cases(93.1%), had an eFI ≥ 0.15.A comparison between the survival group(380 cases)and the death group(244 cases)revealed that the latter had higher eFI values(0.39±0.09 vs.0.29±0.11, t=-11.452, P<0.001), along with higher rates of heart failure, chronic kidney disease, and malignant tumors, as well as lower body mass index, hemoglobin, albumin, and total cholesterol levels, and higher alanine aminotransferase and D-dimer levels(all P<0.05).Logistic regression analysis indicated that eFI( OR=2.322, 95% CI: 1.840-2.929, P<0.001), malignant tumor( OR=1.833, 95% CI: 1.141-2.860, P<0.001), and albumin<35 g/L( OR=1.826, 95% CI: 1.200-2.777, P<0.001)were independent risk factors for in-hospital death in elderly patients aged 80 and over with gastrointestinal bleeding.With every 0.1 increase in eFI, the risk of in-hospital death rose by 1.322 times.The AUC of eFI for predicting in-hospital mortality was 0.751(95% CI: 0.713-0.789, P<0.001).An eFI of ≥0.33 demonstrated a sensitivity of 77.9% and a specificity of 60.3% in predicting in-hospital mortality in elderly patients aged 80 and over with GIB. Conclusions:The eFI serves as an important independent risk factor for in-hospital mortality among patients aged 80 and above who experience GIB.It can effectively assess the prognosis of elderly individuals facing GIB.

Targeted radiation therapy using radionuclides is a favored approach for treating tumors.This procedure involves the delivery of drugs to the lesion site via carriers or interventional methods,followed by the emission of radiation energy that selectively irradiates the lesion tissue.This approach minimizes damage to normal tissue and achieves the desired therapeutic effect.Factors such as the type of therapeutic radionuclide,radiation energy,physical half-life,method of preparation,and toxicity determine their clinical application.In this paper,the characteristics and clinical application of therapeutic radionuclides were reviewed to providing reference for the clinical application of targeted therapeutic radionuclides.

Objective:To explore any differential effect of training wearing a unilateral exoskeleton on the lower-limb motor function of stroke survivors.Methods:Forty stroke survivors were randomly divided into an exoskeleton group ( n=20) and a control group ( n=20). The control group performed conventional lower extremity exercise training while the exoskeleton group received exoskeleton-assisted lower-limb physical therapy. Each participant received eighteen 40-minute training sessions over three weeks. Before and after the intervention, the walking ability, lower-limb function, balance and ability in the activities of daily living of both groups were evaluated. Integrated electromyography (iEMG) of the rectus femoris and tibialis anterior of both legs was also recorded during sit-to-stand transitions to assess the activation of the affected muscles and the symmetry of bilateral muscle activation. Results:After the three weeks, significant improvement was observed in all of the measurements in both groups, but with the exoskeleton group scoring significantly better on average in functional ambulation category grading (1.63±0.72). Both groups′ iEMGs had also improved significantly compared with before treatment, but the exoskeleton group′s average result was by that time significantly better than the control group′s average.Conclusions:A wearable exoskeleton can effectively improve the rehabilitation of walking, lower limb movement, balance and skill in the activities of daily living of persons with subacute stroke. It better activates the affected lower limb muscles and improves the symmetry of bilateral lower limb muscle activation.

Objective To compare clinical and pathological features between autoimmune hepatitis (AIH) patients with positive and negative autoantibodies, and to summarize the experience in diagnosis. Methods A retrospective analysis was performed for the patients who attended Beijing Ditan Hospital from January 2010 to August 2021 and were diagnosed with AIH by liver histopathology, and according to the presence or absence of autoantibodies, they were divided into positive autoantibody group and negative autoantibody group. The two groups were compared in terms of biochemical parameters, immunological features, histopathological features, disease stage, and clinical symptoms and signs. The t -test or the Mann-Whitney U test was used for comparison of continuous data between groups, and the chi-square test or the Fisher's exact test was used for comparison of categorical data. Results A total of 110 patients were enrolled, among whom 78 (71%) had positive autoantibodies and 32 (29%) had negative autoantibodies. Anti-nuclear antibody (ANA), anti-mitochondrial antibody (AMA), and anti-smooth muscle antibody (ASMA) were the main autoantibodies detected, and of all 110 patients, 74 (67.27%) had positive ANA, 1 (0.91%) had positive AMA, 5 (4.55%) had positive ASMA, and 14 (12.73%) had positive anti-Ro-52 antibody. As for clinical and immunological features, compared with the positive autoantibody group, the negative autoantibody group had significantly lower incidence rates of jaundice of the skin and sclera (21.90% vs 50.00%, χ 2 =7.377, P =0.007) and poor appetite (18.80% vs 41.00%, χ 2 =4.979, P =0.026) and significantly lower median levels of direct bilirubin [7.30(4.05~12.10) μmol/L vs 16.80(6.48~69.75) μmol/L, Z =-2.304, P =0.021], IgG [16.40(13.15~18.05) g/L vs 20.30(16.00~27.15) g/L, Z =-2.715, P =0.007], and GLo [30.60(26.00~34.90) g/L vs 37.30(30.50~42.50) g/L, Z =-3.356, P =0.001]. In terms of liver histopathology, compared with the negative autoantibody group, the positive autoantibody group had a significantly higher proportion of patients with lymphocyte infiltration (91.03% vs 68.75%, χ 2 =6.997, P =0.008) and plasma cell infiltration (82.05% vs 50.00%, χ 2 =11.572, P =0.001); compared with the ANA-negative patients, the ANA-positive patients had significantly higher inflammation grade (G1-G4) (9.46%/16.22%/44.59%/29.73% vs 5.56%/27.78%/63.89%/2.78%, Z =-2.179, P =0.029) and fibrosis degree (S1-S4) (37.84%/25.68%/32.43%/4.05% vs 13.89%/41.67%/30.56%/13.89%, Z =-0.082, P =0.037). Conclusion Compared with AIH patients with positive autoantibodies, AIH patients with negative autoantibodies are mostly in the early stage of the disease and tend to have a low level of IgG, with a relatively high rate of missed diagnosis in clinical practice. Early and active liver biopsy is of particular importance.

Objective To investigate the onset of liver inflammation and related predictive factors in patients with HBeAg-positive chronic hepatitis B virus (HBV) infection who have normal alanine aminotransferase (ALT) and a high viral load. Methods A retrospective analysis was performed for the clinical data of 183 patients with HBeAg-positive chronic HBV infection who had normal ALT and a high viral load and were treated from October 2008 to May 2015, and according to the results of liver biopsy, they were divided into hepatitis group and non- hepatitis group. The t -test or Mann-Whitney U testwas used for comparison of normally distributed continuous data between groups, the chi-square test was used for comparison of categorical data. The predictive factors were analyzed by univariate binary logistic regression, the multivariate binary logistic regression was carried out by stepback method, and the cut-off values were analyzed by receiver operating characteristic curve (ROC) and Jordan index. Results There were 37 patients (20.2%) in the hepatitis group and 146 patients (79.8%) in the non-hepatitis group. Compared with the non-hepatitis group, the hepatitis group had a significantly lower proportion of male patients (45.9% vs 68.5%, χ 2 =6.508, P =0.011), a significantly higher level of aspartate aminotransferase [24 (21.25~35.55) U/L vs 21.2 (18.08~ 24.65) U/L, Z =-3.344, P =0.001], and a significantly lower log(HBsAg) value [4.4(4.28~4.49) vs 4.46(4.4~4.74), Z =-2.184, P =0.029]. Log(HBsAg) value was a predictive factor for hepatitis (odds ratio=0.077, P =0.017), and the cutoff value of HBsAg was 33884.4I U/mL. Conclusion Among the patients with HBeAg-positive chronic HBV infection who have normal ALT and a high viral load, 20.2% have liver inflammation, and HBsAg may be a predictive factor for liver inflammation.

Objective:To study the predictors of postpartum hepatitis in pregnant women with chronic HBV infection.Methods:In this retrospective study, liver function and hepatitis B virology tests of pregnant women with chronic HBV infection at delivery and within 48 weeks were collected from the clinical medical system after the enrollment of eligible patients. Statistical analysis was performed on the obtained data.Results:A total of 533 pregnant women meeting the criteria were enrolled, and the average age of all patients was 29.5±3.7. A total of 408 pregnant women took antiviral drugs during pregnancy for prevention of mother-to-child transmission; 231 patients developed hepatitis within 1 year after delivery. There were significant differences in alanine transaminase (ALT), aspartate transaminase (AST), HBV DNA during delivery, hepatitis B e antigen (HBeAg) during delivery and baseline HBeAg between patients with and without hepatitis. Multivariate binary logistic regression analysis showed that HBeAg ( OR=0.19, 0.074-0.473; P<0.001), ALT ( OR=1.05, 1.021-1.071; P<0.001), albumin ( OR=0.91, 0.833-0.995; P=0.038), platelet ( OR=0.995, 0.992-0.999; P=0.01), neutrophils ( OR=0.98, 0.973-0.995; P=0.004) had significant difference. Conclusions:Baseline HBeAg and ALT are powerful predictors of postpartum hepatitis in pregnant women with chronic HBV infection.
