OBJECTIVE: To compare the effectiveness of single-stage vascularized lymph node transfer (VLNT) combined with lymphaticovenular anastomosis (LVA) and liposuction (LS) (3L) versus LVA combined with LS (2L) for the treatment of moderate-to-late stage upper limb lymphedema following breast cancer surgery. METHODS: A retrospective analysis was conducted on the clinical data of 16 patients with moderate-to-late stage upper limb lymphedema after breast cancer surgery, treated between June 2022 and June 2024, who met the selection criteria. Patients were divided into 3L group (n=7) and 2L group (n=9) based on the surgical approach. There was no significant difference (P>0.05) in baseline data between the groups, including age, body mass index, duration of edema, volume of liposuction, International Society of Lymphology (ISL) stage, preoperative affected limb volume, preoperative circumferences of the affected limb at 12 levels (from 4 cm distal to the wrist to 42 cm proximal to the wrist), preoperative Lymphoedema Quality of Life (LYMQoL) score, and frequency of cellulitis episodes. The 2L group underwent LS on the upper arm and proximal forearm and LVA on the middle and distal forearm. The 3L group received additional VLNT in the axilla, with the groin serving as the donor site. Outcomes were assessed included the change in affected limb volume at 12 months postoperatively, and comparisons of limb circumferences, LYMQoL score, and frequency of cellulitis episodes between preoperative and 12-month postoperative. Ultrasound evaluation was performed at 12 months in the 3L group to assess lymph node viability. RESULTS: Both groups were followed up 12-20 months, with an average of 15.13 months. There was no significant difference in the follow-up time between the groups (t=-1.115, P=0.284). All surgical incisions healed by first intention. No adverse events, such as flap infection or necrosis, occurred in the 3L group. At 12 months after operation, ultrasound confirmed good viability of the transferred lymph nodes in the 3L group. Palpation revealed significant improvement in skin fibrosis and improved skin softness in both groups. Affected limb volume significantly decreased in both groups postoperatively (P<0.05). The reduction in limb volume significantly greater in the 3L group compared to the 2L group (P<0.05). Circumferences at all 12 measured levels significantly decreased in both groups compared to preoperative values (P<0.05). The reduction in circumference at all 12 levels was better in the 3L group than in the 2L group, with significant differences observed at 7 levels (8, 12, 16, 30, 34, 38, and 42 cm) proximal to the wrist (P<0.05). Both groups showed significant improvement in the frequency of cellulitis episodes and LYMQoL scores postoperatively (P<0.05). While the improvement in LYMQoL scores at 12 months did not differ significantly between groups (P>0.05), the reduction in cellulitis episodes was significantly greater in the 3L group compared to the 2L group (P<0.05). CONCLUSION The combination of VLNT+LVA+LS provides more durable and comprehensive outcomes for moderate-to-late stage upper limb lymphedema after breast cancer surgery compared to LVA+LS, offering an improved therapeutic solution for patients.

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C₀), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug‍-‍drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

Objective:To investigate the preventive and therapeutic effects and mechanisms of Dachaihu decoction(DCD)on dextran sodium sulfate(DSS)-induced ulcerative colitis(UC)and liver injury in mice,as well as the association between DCD benefits and gut microbiota modulation.Methods:Mice were treated with DCD(20.10 and 10.05 g/kg)for 2 weeks,with free access to drinking water containing 3%DSS in the second week to induce UC.Histopathological examination,RT-qPCR and 16S rRNA sequencing were used to investigate the effect of DCD on UC mice.Results:DCD pretreatment significantly alleviated weight loss,bloody diarrhea with mucus,histopathological abnormalities of the colon,and colon shortening in mice with DSS-induced UC.In addition,DCD pretreat-ment significantly upregulated the levels of Occludin,ZO-1,and MUC-2 in the colon and protected the intestinal barrier of mice.DCD pretreatment also alleviated inflammatory cell infiltration in the colon and the liver and significantly reduced the expression levels of the proinflammatory factors such as IL-1β,IL-6,TNF-α,iNOS,COX-2,and NLRP3,thereby exerting a protective effect against UC and liver injury.It should be noted that DCD corrected gut micro-biota imbalance in UC mice by enriching probiotic bacteria such as Lactobacillus and Bifidobacterium and reducing harmful bacteria such as Norank_f_Desulfovibrionaceae and Escherichia-Shigella.Conclusion:DCD can alleviate DSS-induced UC and exert a liver-protecting effect by protecting intestinal barrier,inhibiting inflam-mation,and regulating gut microbiota.

ObjectiveTo explore the characteristics of circadian rhythm of blood pressure in patients with masked hypertension （MH） and its relationship with twelve two-hour peirods， providing a basis for early detection and intervention of MH. MethodsPatients who underwent 24-hour ambulatory blood pressure examination in the ambulatory blood pressure room of Jiangsu Province Hospital of Chinese Medicine from January to December 2022 were enrolled， and according to their outpatient blood pressure measurements， 24-hour ambulatory blood pressure monitoring and follow-up survey results， the MH， essential hypertension （EH） and normal blood pressure groups were classified， with 50 cases in each group. The general data， office blood pressure and 24-hour ambulatory blood pressure monitoring data were collected. The circadian rhythm of blood pressure including 24-hour average systolic blood pressure （24h SBP）， daytime average systolic blood pressure （d SBP）， nighttime average systolic blood pressure （n SBP）， 24-hour average diastolic blood pressure （24h DBP）， daytime average diastolic blood pressure （d DBP）， and nighttime average diastolic blood pressure （n DBP） were compared among the groups， and the nighttime blood pressure dipping percentage was calculated. The type of circadian rhythm was determined based on the nighttime blood pressure dipping percentage. The variability of blood pressure including 24h SBP standard deviation （24h SBP-SD）， d SBP standard deviation （dSBP-SD）， n SBP standard deviation （nSBP-SD）， 24h DBP standard deviation （24h DBP-SD）， d DBP standard deviation （dDBP-SD）， and n DBP standard deviation （nDBP-SD） were compared among groups， and the corresponding coefficient of variation （CV）， that is， 24h SBP-CV， d SBP-CV， n SBP-CV， 24h DBP-CV， d DBP-CV and n DBP-CV， were calculated. Based on the 24-hour ambulatory blood pressure monitoring results， the twelve two-hour average SBP and DBP in each group were calculated and compared. Simultaneously， patients with EH were divided into grades 1， 2， and 3 for further stratified analysis. ResultsThe age of the MH group was significantly higher than that of the EH group and the normal blood pressure group （P＜0.01）. The body mass index （BMI） and the proportion of smoking and alcohol consumption in the MH group and the EH group were significantly higher than those in the normal blood pressure group （P＜0.05 or P＜0.01）. In the normal blood pressure group， there were 49 dipper patterns （98.0%） and one non-dipper pattern （2.0%）； in the MH group， there were two dipper patterns （4.0%）， 29 non-dipper patterns （58.0%） and 19 reverse-dipper patterns （38.0%）； in the EH group， there were 20 dipper patterns （40.0%）， 23 non-dipper patterns （46.0%） and seven reverse-dipper patterns （14.0%）. Compared to the normal blood pressure group， the groups of MH and EH had significantly decreased proportion of dipper pattern and increased proportion of non-dipper and reverse-dipper pattern （P＜0.01）； the proportion of dipper pattern in the MH group was lower than that in the EH group， while the proportion of reverse-dipper pattern was higher （P＜0.01）. Compared to those in the normal blood pressure group， n SBP and n DBP in the MH group， as well as the the average SBP and average DBP at Zi hour （子时， 23：00-1：00）， Chou hour （丑时， 1：00-3：00）， Yin hour （寅时， 3：00-5：00）， Mao hour （卯时， 5：00-7：00） and average SBP at Hai hour （亥时， 21：00-23：00） in the MH group increased，while the average DBP at Si hour （巳时， 9：00-11：00） decreased （P＜0.01）； 24h SBP， 24h DBP， d SBP， d DBP， n SBP， and n DBP，d SBP-SD， n SBP-SD，n DBP-SD increased， as well as the average SBP and average DBP at twelve two-hour periods increased in the EH group，while the 24h SBP-CV， 24h DBP-CV，and d DBP-CV in the EH group decreased（P＜0.05 or P＜0.01）. The EH group had higher 24h SBP， 24h DBP， d SBP， d DBP， n SBP， n DBP， 24h DBP-SD and n DBP-SD ， as well as higher average SBP and DBP at all twelve two-hour periods， and lower d DBP-CV than the MH group（P＜0.05 or P＜0.01）. The EH group had 18 cases of grade 1 （36.0％）， 19 cases of grade 2 （38.0％） and 13 cases of grade 3 （26.0％）， with no significant differences among groups （P＞0.05）. ConclusionThe circadian rhythm of blood pressure in MH patients are mostly non-dipper and reverse-dipper patterns， and the abnormal elevation of blood pressure is obvious at Zi hour， Chou hour， Yin hour and Mao hour （23：00-7：00）.

Objective:We aimed to develop a novel visualized model based on nomogram to predict postoperative overall survival.Methods:This was a multicenter, retrospective, observational cohort study, including participants with histologically confirmed gastric and colorectal cancer who underwent radical surgery from 11 medical centers in China from August 1, 2015 to June 30, 2018. Baseline characteristics, histopathological data and nutritional status, as assessed using Nutrition Risk Screening 2002 (NRS 2002) score and the scored Patient-Generated Subjective Global Assessment, were collected. The least absolute shrinkage and selection operator regression and Cox regression were used to identify variables to be included in the predictive model. Internal and external validations were performed.Results:There were 681 and 127 patients in the training and validation cohorts, respectively. A total of 188 deaths were observed over a median follow-up period of 59 (range: 58 to 60) months. Two independent predictors of NRS 2002 and Tumor-Node-Metastasis (TNM) stage were identified and incorporated into the prediction nomogram model together with the factor of age. The model's concordance index for 1-, 3- and 5-year overall survival was 0.696, 0.724, and 0.738 in the training cohort and 0.801, 0.812, and 0.793 in the validation cohort, respectively.Conclusions:In this study, a new nomogram prediction model based on NRS 2002 score was developed and validated for predicting the overall postoperative survival of patients with gastric colorectal cancer. This model has good differentiation, calibration and clinical practicability in predicting the long-term survival rate of patients with gastrointestinal cancer after radical surgery.

OBJECTIVE To evaluate the effectiveness， safety， economy， innovation， suitability and accessibility of recombinant Mycobacterium tuberculosis fusion protein （EC）， and to provide evidence for selecting skin detection methods for tuberculosis infection diagnosis and auxiliary diagnosis of tuberculosis. METHODS The effectiveness and safety of EC compared with purified protein derivative of tuberculin （TB-PPD） were analyzed by the method of systematic review. Cost minimization analysis， cost-effectiveness analysis and cost-utility analysis were used to evaluate the short-term economy of EC compared with TB-PPD， and cost-utility analysis was used to evaluate the long-term economy. The evaluation dimensions of innovation， suitability and accessibility were determined by systematic review and improved Delphi expert consultation， and the comprehensive score of EC and TB-PPD in each dimension were calculated by the weight of each indicator. RESULTS The scores of effectiveness， safety， economy， innovation and suitability of EC were all higher than those of TB-PPD. The affordability scores of the two drugs were consistent， while the availability score of EC was lower than those of TB-PPD. After considering dimensions and index weight， the scores of effectiveness， safety， economy， innovation， suitability， accessibility and the comprehensive score of EC were all higher than those of TB-PPD. CONCLUSIONS Compared with TB-PPD， EC performs better in all dimensions of effectiveness， safety， economy， innovation， suitability and accessibility. However， it is worth noting that EC should further improve its availability in the dimension of accessibility.

ObjectiveTo investigate the current situation of personality traits and job satisfaction of pediatric therapists in Jiangsu province, and to explore the correlation between them and the related factors of job satisfaction. MethodsFrom June, 2021 to February, 2022, random cluster sampling method was adopted after field investigating several pediatric hospitals and institutions in Jiangsu. Online questionnaires were sent out to pediatric therapists in different settings in eleven cities in Jiangsu. The questionnaires included Minnesota Satisfaction Questionnaire (MSQ), Eysenck Personality Questionnaire-Revised Short Scale for Chinese (EPQ-RSC) and self-made scale of demographic characteristics and working status. ResultsAll of the questionaires were taken back, in which 165 were valid (83.33%). Among the three dimensions of psychoticism, extraversion and neuroticism, the intermediate type accounted for 66.06%, 38.79% and 40.00%, respectively. The overall satisfaction of job was (3.80±0.55), the internal satisfaction was (3.88±0.53), and the external satisfaction was (3.59±0.69). There was significant difference in the satisfaction among different types of work institution, monthly incomes, levels of parental support and neuroticism (P < 0.05). Multiple linear regression showed that the internal satisfaction and overall satisfaction were related with neuroticism, monthly income and parental support (P < 0.05), while external satisfaction was related with the neuroticism and parental support (P < 0.05). The level of neuroticism was negatively correlated with the internal satisfaction, the external satisfaction and overall satisfaction (|r| > 0.337, P < 0.001), and the level of extraversion was postively correlated with the external satisfaction (r = 0.155, P < 0.05). ConclusionThe job satisfaction of pediatric therapists is fine in Jiangsu, and is ralated with the level of neuroticism, the monthly income and the level of parental support. The levels of neuroticism and extraversion correlate with the job satisfaction.
