Objective:To analyze the immune reconstitution after BTKi treatment in patients with chronic lymphocytic leukemia(CLL).Methods:The clinical and laboratorial data of 59 CLL patients admitted from January 2017 to March 2022 in Fujian Medical University Union Hospital were collected and analyzed retrospectively.Results:The median age of 59 CLL patients was 60.5(36-78).After one year of BTKi treatment,the CLL clones(CD5+/CD19+)of 51 cases(86.4％)were significantly reduced,in which the number of cloned-B cells decreased significantly from(46±6.1)× 109/L to(2.3±0.4)× 109/L(P=0.0013).But there was no significant change in the number of non-cloned B cells(CD19+minus CD5+/CD19+).After BTKi treatment,IgA increased significantly from(0.75±0.09)g/L to(1.31±0.1)g/L(P＜0.001),while IgG and IgM decreased from(8.1±0.2)g/L and(0.52±0.6)g/L to(7.1±0.1)g/L and(0.47±0.1)g/L,respectively(P＜0.001,P=0.002).BTKi treatment resulted in a significant change in T cell subpopulation of CLL patients,which manifested as both a decrease in total number of T cells from(2.1±0.1)× 109/L to(1.6±0.4)× 109/L and NK/T cells from(0.11±0.1)× 109/L to(0.07±0.01)× 109/L(P=0.042,P=0.038),both an increase in number of CD4+cells from(0.15±6.1)× 109/L to(0.19±0.4)× 109/L and CD8+cells from(0.27±0.01)× 109/L to(0.41±0.08)× 109/L(both P＜0.001).BTKi treatment also up-regulated the expression of interleukin(IL)-2 while down-regulated IL-4 and interferon(IFN)-γ.However,the expression of IL-6,IL-10,and tumor necrosis factor(TNF)-α did not change significantly.BTKi treatment could also restored the diversity of TCR and BCR in CLL patients,especially obviously in those patients with complete remission(CR)than those with partial remission(PR).Before and after BTKi treatment,Shannon index of TCR in patients with CR was 0.02±0.008 and 0.14±0.001(P＜0.001),while in patients with PR was 0.01±0.03 and 0.05±0.02(P＞0.05),respectively.Shannon index of BCR in patients with CR was 0.19±0.003 and 0.33±0.15(P＜0.001),while in patients with PR was 0.15±0.009 and 0.23±0.18(P＜0.05),respectively.Conclusions:BTKi treatment can shrink the clone size in CLL patients,promote the expression of IgA,increase the number of functional T cells,and regulate the secretion of cytokines such as IL-2,IL-4,and IFN-γ.BTKi also promote the recovery of diversity of TCR and BCR.BTKi treatment contributes to the reconstitution of immune function in CLL patients.

Objective: To establish a nomogram prognostic model for predicting the 5-, 10-, and 15-year overall survival (OS) of non-metastatic renal cell carcinoma patients managed with radical nephrectomy (RN), compare the modelled results with the results of pure pathologic staging, the Karakiewicz nomogram and the Mayo Clinic Stage, Size, Grade, and Necrosis (SSIGN) score commonly used in foreign countries, and stratify the patients into different prognostic risk subgroups. Methods: A total of 1 246 non-metastatic renal cell carcinoma patients managed with RN in Sun Yat-sen University Cancer Center (SYSUCC) from 1999 to 2020 were retrospectively analyzed. Multivariate Cox regression analysis was used to screen the variables that influence the prognosis for nomogram establishment, and the bootstrap random sampling was used for internal validation. The time-receiver operating characteristic curve (ROC), the calibration curve and the clinical decision curve analysis (DCA) were applied to evaluate the nomogram. The prediction efficacy of the nomogram and that of the pure pathologic staging, the Karakiewicz nomogram and the SSIGN score was compared through the area under the curve (AUC). Finally, patients were stratified into different risk subgroups according to our nomogram scores. Results: A total of 1 246 patients managed with RN were enrolled in this study. Multivariate Cox regression analysis showed that age, smoking history, pathological nuclear grade, sarcomatoid differentiation, tumor necrosis and pathological T and N stages were independent prognostic factors for RN patients (all P<0.05). A nomogram model named SYSUCC based on these factors was built to predict the 5-, 10-, and 15-year survival rate of the participating patients. In the bootstrap random sampling with 1 000 iterations, all these factors occurred for more than 800 times as independent predictors. The Harrell's concordance index (C-index) of SYSUCC was higher compared with pure pathological staging [0.770 (95% CI: 0.716-0.823) vs 0.674 (95% CI: 0.621-0.728)]. The calibration curve showed that the survival rate as predicted by the SYSUCC model simulated the actual rate, while the clinical DCA showed that the SYSUCC nomogram has a benefit in certain probability ranges. In the ROC analysis that included 857 patients with detailed pathological nuclear stages, the nomogram had a larger AUC (5-/10-year AUC: 0.823/0.804) and better discriminating ability than pure pathological staging (5-/10-year AUC: 0.701/0.658), Karakiewicz nomogram (5-/10-year AUC: 0.772/0.734) and SSIGN score (5-/10-year AUC: 0.792/0.750) in predicting the 5-/10-year OS of RN patients (all P<0.05). In addition, the AUC of the SYSUCC nomogram for predicting the 15-year OS (0.820) was larger than that of the SSIGN score (0.709), and there was no statistical difference (P<0.05) between the SYSUCC nomogram, pure pathological staging (0.773) and the Karakiewicz nomogram (0.826). The calibration curve was close to the standard curve, which indicated that the model has good predictive performance. Finally, patients were stratified into low-, intermediate-, and high-risk subgroups (738, 379 and 129, respectively) according to the SYSUCC nomogram scores, among whom patients in intermediate- and high-risk subgroups had a worse OS than patients in the low-risk subgroup (intermediate-risk group vs. low-risk group: HR=4.33, 95% CI: 3.22-5.81, P<0.001; high-risk group vs low-risk group: HR=11.95, 95% CI: 8.29-17.24, P<0.001), and the high-risk subgroup had a worse OS than the intermediate-risk group (HR=2.63, 95% CI: 1.88-3.68, P<0.001). Conclusions: Age, smoking history, pathological nuclear grade, sarcomatoid differentiation, tumor necrosis and pathological stage were independent prognostic factors for non-metastasis renal cell carcinoma patients after RN. The SYSUCC nomogram based on these independent prognostic factors can better predict the 5-, 10-, and 15-year OS than pure pathological staging, the Karakiewicz nomogram and the SSIGN score of patients after RN. In addition, the SYSUCC nomogram has good discrimination, agreement, risk stratification and clinical application potential.

Objective: To examine the changes of depressive and anxiety symptoms in school aged children during home confinement and to identify possible influence of learning and lifestyle behaviors on mental health changes. Methods: The population of this study were obtained from the "Tongji Mental Health Cohort". Two primary schools in Wuhan were selected through cluster sampling and students in grade 2-5 were surveyed. This study was divided into two stages. In the first stage (T1=during home learning), a total of 2 588 valid questionnaires were collected. In the second phase (T2=during school learning), 2 424 children were followed up successfully. Combining the results of the depression and anxiety symptoms of the two surveys of children respectively to classify the children s psychological outcomes. Association between home learning and lifestyle behaviors with the change of psychological symptoms in school aged children were estimated by disordered multi classification Logistic regression. Results: The prevalence of depressive and anxiety symptoms were 28.9% and 21.0% in school aged children at T1, 35.6% and 30.6% at T2, respectively. The aggravation and persistence of depressive and anxiety symptoms in children were partly related to their home learning and lifestyle behaviors. Concentration in class（ OR=0.63，95%CI =0.45-0.89）, frequent interaction with teachers ( OR =0.74, 95% CI = 0.57- 0.95 ), participation in physical exercise at home ( OR =0.60, 95% CI =0.41-0.87) was negatively associated with depressive symptoms in children. Time spent on playing video games ( OR =1.15, 95% CI =1.06-1.24) and fear of infection with coronavirus disease 2019 ( OR =1.83, 95% CI =1.39-2.42) were positively associated with anxiety in children. Boys（ OR=0.70， 0.63 ） were more likely to suffer from depression and anxiety symptoms than girls. Conclusion The prevalence of depressive and anxiety symptoms among school aged children increased when they went back to school after home confinement, suggesting more attention are needed for mental health intervention among school aged children.

Objective: To determine the association between physical health fitness with Chinese reading ability of schoolaged children, so as to provide evidence for improving children s reading ability. Methods: A questionnaire survey was conducted among 1 923 school aged children in grades 2-6 in a primary school in Wuhan, Hubei Province, China. The questionnaire included basic demographic information and Dyslexia Checklist for Chinese Children and the Pupil Rating Scale Revised Screening. At the same time, participants underwent physical fitness tests which included an assessment of height, weight, and lung capacity, as well as a 50 meter run, sit forward bend, one minute skipping rope task, sit ups, and a 50 × 8 round trip. Results: A total of 59 children were identified with dyslexia. Normal children achieved higher scores than children with dyslexia in the total physical health score, as well as the one minute skipping rope score, one minute sit up score, and sitting forward score ( P <0.05). Multiple linear regression analyses showed that the reading ability of girls was higher than that of boys ( β =-3.04, P <0.01), and the children who regularly participated in more intense physical activity and who had higher fitness scores had a higher reading ability ( β =-1.68, -0.08, P <0.01). Children s reading ability increased significantly with parental educational level( P <0.05). Conclusion Gender, parents education level, physical exercise intensity, and children s physical fitness were identified as influencing factors of school age children s reading ability. A positive correlation was found between children s physical health level and reading ability.

Background:Clinical outcomes of undifferentiated arthritis (UA) are diverse,and only 40 ％ of patients with UA develop rheumatoid arthritis (RA) after 3 years.Discovering predictive markers at disease onset for further intervention is critical.Therefore,our objective was to analyze the clinical outcomes of UA and ascertain the predictors for RA development.Methods:We performed a prospective,multi-center study from January 2013 to October 2016 among Chinese patients diagnosed with UA in 22 tertiary-care hospitals.Clinical and serological parameters were obtained at recruitment.Follow-up was undertaken in all patients every 12 weeks for 2 years.Predictive factors of disease progression were identified using multivariate Cox proportional hazards regression.Results:A total of 234 patients were recruited in this study,and 17 (7.3％) patients failed to follow up during the study.Among the 217 patients who completed the study,83 (38.2％) patients went into remission.UA patients who developed RA had a higher rheumatoid factor (RF)-positivity (42.9％ vs.16.8％,x2=8.228,P=0.008),anti-cyclic citrullinated peptide (CCP) antibodypositivity (66.7％ vs.10.7％,x2 =43.897,P ＜ 0.001),and double-positivity rate of RF and anti-CCP antibody (38.1％ vs.4.1％,x2 =32.131,P ＜ 0.001) than those who did not.Anti-CCP antibody but not RF was an independent predictor for RA development (hazard ratio 18.017,95％ confidence interval:5.803-55.938;P ＜ 0.001).Conclusion:As an independent predictor of RA,anti-CCP antibody should be tested at disease onset in all patients with UA.

Objective The aims of this study were to assess incidences and characteristics of arterial thromboembolic events (ATEs) and venous thromboembolic events (VTEs) in Chinese patients with idiopathic membranous nephropathy (IMN), and to identify the predisposing risk factors of them.Methods A total of 766 consecutive Chinese patients with IMN were enrolled in this retrospective cohort study. The cumulative incidences of newly diagnosed ATEs and VTEs were calculated using Kaplan-Meier methods. Univariable risk prediction model analysis followed by multivariable survival analysis was used to evaluate the potential risk factors of ATE and VTE.Results At 0.5, 1, 2, 3, and 5 years after biopsy diagnosis of IMN, the cumulative incidence of newly diagnosed ATEs were 4.3%, 5.7%, 6.3%, 7.1%, and 8.0%, and of newly diagnosed VTEs were 5.9%, 6.8%, 6.9%, 7.0%, and 7.2%, respectively. In 78 ATEs events (71 patients), cardiovascular diseases, thrombotic ischemic stroke (IS) and peripheral artery disease accounted for 50%, 45% and 5% respectively; in 60 VTEs events(53 patients), the deep vein thrombosis, renal vein thrombosis and pulmonary embolism accounted for 60%, 13% and 27% respectively. At the time of event, 42.1% patients with ATEs and 81.5% patients with VTEs were at nephrotic syndrome(NS) status (χ =18.1, P<0.001). Severe proteinuria, aging, smoking, hypertension and prior ATE history were associated with ATEs. Aging was demonstrated as the independent risk factor for ATEs (P=0.001), and hypoalbuminemia was the dominant independent risk factor for VTEs (P=0.03). Conclusions Patients with IMN have increased incidences of ATEs and VTEs, and most of events occurred within the first 6 months of the disease. IS was very common in ATEs in our cohort. Severe proteinuria and classic risk factors for atherosclerosis were associated with onset of ATEs. Hypoalbuminemia independently predicted VTEs. Risks of both ATEs and VTEs were particularly high in the status of NS, particularly VTEs.

Objective To investigate the efficacy and safety of rituximab (RTX) in the treatment of idiopathic membranous nephropathy (IMN) with nephrotic syndrome with a systematic review and meta-analysis. Methods PubMed, Embase, Cochrane Library and Clinical Trials (December 2016) were searched to identify researches investigating the treatment of RTX in adult patients with biopsy-proven IMN. Complete remission (CR) or partial remission was regarded as effective therapy, and the cumulated remission rate was calculated. Result Seven studies involved 120 patients (73% were men) were included in our systematic review and meta-analysis. All were prospective observation cohort studies or matched-cohort studies, mainly came from two medical centers, and one study was multi-centric (four nephrology units in northern Italy). The creatinine clearance was more than 20 ml/(min·1.73 m) and persistent proteinuria higher than 3.5 g/d for at least 6 months. All patients received treatment previously [44 (36.7%) had immunosuppressive treatment]. In 12- and 24-month, 56% (95%CI, 0.47-0.65) and 68% (95%CI, 0.41-0.87) patients could reach remission, while 15% (95%CI, 0.09-0.23) and 20% (95%CI, 0.12-0.32) patients could reach CR. The reduction in proteinuria was gradual and obvious, paralleled with upward trend of serum albumin level and decreasing serum cholesterol level. Renal functions were stable. Relapses happened in 24 months were around 8%. RTX related adverse events were mild and were mostly infusion-related reactions. Conclusions RTX treatment in IMN was efficient, well tolerated and safe. More than 60% patients can reach partial remission or CR in 24 months, and relapse is rare. Adverse events of RTX are mostly infusion-related reactions and generally mild.

To analyze the medication features and the regularity of prescriptions of traditional Chinese medicine in treating patients with Qi-deficiency and blood-stasis syndrome of chronic heart failure based on modern literature. In this article, CNKI Chinese academic journal database, Wanfang Chinese academic journal database and VIP Chinese periodical database were all searched from January 2000 to December 2015 for the relevant literature on traditional Chinese medicine treatment for Qi-deficiency and blood-stasis syndrome of chronic heart failure. Then a normalized database was established for further data mining and analysis. Subsequently, the medication features and the regularity of prescriptions were mined by using traditional Chinese medicine inheritance support system(V2.5), association rules, improved mutual information algorithm, complex system entropy clustering and other mining methods. Finally, a total of 171 articles were included, involving 171 prescriptions, 140 kinds of herbs, with a total frequency of 1 772 for the herbs. As a result, 19 core prescriptions and 7 new prescriptions were mined. The most frequently used herbs included Huangqi(Astragali Radix), Danshen(Salviae Miltiorrhizae Radix et Rhizoma), Fuling(Poria), Renshen(Ginseng Radix et Rhizoma), Tinglizi(Semen Lepidii), Baizhu(Atractylodis Macrocephalae Rhizoma), and Guizhi(Cinnamomum Ramulus). The core prescriptions were composed of Huangqi(Astragali Radix), Danshen(Salviae Miltiorrhizae Radix et Rhizoma) and Fuling(Poria), etc. The high frequent herbs and core prescriptions not only highlight the medication features of Qi-invigorating and blood-circulating therapy, but also reflect the regularity of prescriptions of blood-circulating, Yang-warming, and urination-promoting therapy based on syndrome differentiation. Moreover, the mining of the new prescriptions provide new reference and inspiration for clinical treatment of various accompanying symptoms of chronic heart failure. In conclusion, this article provides new reference for traditional Chinese medicine in the treatment of chronic heart failure.

Objective To investigate whether glomerular density (GD) could be an independent prognostic factor for patients of IgA nephropathy with estimated glomerular filtration rate (eGFR) of 30 to 60 ml/min per 1.73 m, or for patients with time-average proteinuria < 0.5 g/d. Methods A total of 173 patients with biopsy-confirmed IgA nephropathy diagnosed from January 2000 to December 2010 were included. All of these patients were followed up for more than 5 years. The endpoint was a > 30% of decline in eGFR from baseline after 5-year follow-up. The optimal cut-off value of GD was calculated by ROC curve. Kaplan-Meier method and Cox regression analysis was used for survival analysis. Results A 30% of decline in eGFR occurred in 14.5% of all patients. The optimal diagnostic cut-off value of GD was 1.99/mm(AUC = 0.90, sensitivity = 84.0%, specificity = 81.8%) determined by ROC curve. The low GD group (GD < 1.99 per mm) experienced a significant increase in renal endpoint for patients with eGFR of 30 to 60 ml/min per 1.73 m(six patients in lower GD group, while one patient in the other group). For patients with time-average proteinuria < 0.5 g/d, the lower GD group showed a higher eGFR decline from baseline (4.5±16.7 ml/min per 1.73 mvs. -8.1±21.4 ml/min per 1.73 m, P = 0.038); two patients in this group reached the endpoint, while no patients in the higher GD group did. Conclusion GD could be an independent prognostic factor for patients of IgA nephropathy with eGFR at 30 to 60 ml/min per 1.73 mof body surface, particularly for those with time-averaged amount of urine protein less than 0.5 g per day.
