RESUMO

BACKGROUND: The survival outcomes of patients with esophageal squamous cell carcinoma (ESCC) after open or thoracoscopic upfront esophagectomy remained unclear. OBJECTIVE: The aim of this retrospective study was to compare overall survival between open and thoracoscopic esophagectomy for ESCC patients without neoadjuvant chemodatiotherapy (CRT). METHODS: The Taiwan Cancer Registry was investigated for ESCC cases from 2008 to 2016. We enrolled 2053 ESCC patients receiving open (n = 645) or thoracoscopic (n = 1408) upfront esophagectomy. One-to-two propensity score matching between the two groups was performed. Stage-specific survival was compared before and after propensity score matching. Univariate analysis and multivariate analysis were used to identify risk factors. RESULTS: After one-to-two propensity score matching, a total of 1299 ESCC patients with comparable clinic-pathologic features were identified. There were 433 patients in the open group and 866 patients in the thoracoscopic group. The 3-year overall survival of matched patients in the thoracoscopic group was better than that of matched patients in the open group (58.58% vs 47.62%, P = 0.0002). Stage-specific comparisons showed thoracoscopic esophagectomy is associated with better survival than open esophagectomy in patients with pathologic I/II ESCC. In multivariate analysis, surgical approach was still an independent prognostic factor before and after one-to-two propensity score matching. CONCLUSION: This propensity-matched study revealed that thoracoscopic esophagectomy could provide better survival than open esophagectomy in ESCC patients without neoadjuvant CRT.

RESUMO

BACKGROUND: Talaromyces marneffei (T. Marneffei) infection is considered as an indicator of immunosuppression in immunocompromised individuals, leading to multiple organ damage. Our study aimed to evaluate both the clinical characteristics and immunological features of pediatric patients infected with T. marneffei from our institute, providing novel insights into diagnosis and treatment for this life-threatening disease. METHOD: Thirteen pediatric patients with T. marneffei infection were enrolled in Guangzhou Women and Children's Medical Center during 2012 to 2020. Clinical data and laboratory findings were collected and further analyzed. Pearson correlation coefficient was calculated to determine the relationship between serum immunoglobulins (Igs) levels and white blood cell count, or the absolute lymphocyte count. RESULTS: Patients were diagnosed as having T. Marneffei infection mainly based on the results of fungal culture and Gram stain of specimens. The most common presentations were fever (69%), pneumonia (38%) and immunodeficiency (38%). The total levels of Igs (IgE, IgA, and IgM) were positively correlated with both white blood cell count and absolute lymphocyte count. CONCLUSION: Serum Ig expression Pattern in patients diagnosed with T. marneffei infection might serve as an effective prognostic marker which would help with the development of early interventions for children with this fatal disease.

RESUMO

Periodontitis is an inflammatory disease initiated by dysbiosis of the local microbial community. Periodontitis can result in destruction of tooth-supporting tissue; however, overactivation of the host immune response is the main reason for alveolar bone loss. Periodontal tissue cells, immune cells, and even further activated osteoclasts and neutrophils play pro-inflammatory or anti-inflammatory roles. Traditional therapies for periodontitis are effective in reducing the microbial quantities and improving the clinical symptoms of periodontitis. However, these methods are non-selective, and it is still challenging to achieve an ideal treatment effect in clinics using the currently available treatments and approaches. Exosomes have shown promising potential in various preclinical and clinical studies, including in the diagnosis and treatment of periodontitis. Exos can be secreted by almost all types of cells, containing specific substances of cells: RNA, free fatty acids, proteins, surface receptors and cytokines. Exos act as local and systemic intercellular communication medium, play significant roles in various biological functions, and regulate physiological and pathological processes in numerous diseases. Exos-based periodontitis diagnosis and treatment strategies have been reported to obtain the potential to overcome the drawbacks of traditional therapies. This review focuses on the accumulating evidence from the last 5 years, indicating the therapeutic potential of the Exos in preclinical and clinical studies of periodontitis. Recent advances on Exos-based periodontitis diagnosis and treatment strategies, existing challenges, and prospect are summarized as guidance to improve the effectiveness of Exos on periodontitis in clinics.

RESUMO

BACKGROUND: For patients with locoregional esophageal squamous cell carcinoma (ESCC), survival outcomes among neoadjuvant chemoradiotherapy followed by operation (nCRT-OP), definitive chemoradiotherapy (dCRT), and esophagectomy alone remain controversial. PATIENTS AND METHODS: Information from the 2008-2016 Taiwan Cancer Registry was used. A total of 7637 cT1b-4, N0/+, M0 ESCC patients receiving nCRT-OP (n = 1955), dCRT (n = 4122), or esophagectomy alone (n = 1560) were included. Propensity score matching was performed to balance clinical variables among the three groups. Stage-specific overall survival was compared before and after propensity score matching. Univariable and multivariable analyses were performed to identify prognostic factors. RESULTS: Propensity score matching resulted in 1407 cases for comparison. The 5-year overall survival rates for matched patients treated via dCRT, nCRT-OP, and esophagectomy alone were 19.77%, 31.23%, and 30.52%, respectively (p < 0.001). On multivariable analysis, treatment modality was still an independent prognostic factor both before and after propensity score matching. nCRT-OP and esophagectomy alone were associated with significantly better overall survival than dCRT for locoregional ESCC patients. CONCLUSIONS: This propensity-matched study revealed that nCRT-OP and esophagectomy provided better survival than dCRT in cT1b-4, N0/+, M0 ESCC patients.

RESUMO

Periodontitis is a chronic inflammatory disease that leads to the destruction of both soft and hard periodontal tissues. Complete periodontal regeneration in clinics using the currently available treatment approaches is still a challenge. Mesenchymal stem cells (MSCs) have shown promising potential to regenerate periodontal tissue in various preclinical and clinical studies. The poor survival rate of MSCs during in vivo transplantation and host immunogenic reaction towards MSCs are the main drawbacks of direct use of MSCs in periodontal tissue regeneration. Autologous MSCs have limited sources and possess patient morbidity during harvesting. Direct use of allogenic MSCs could induce host immune reaction. Therefore, the MSC-based indirect treatment approach could be beneficial for periodontal regeneration in clinics. MSC culture conditioned medium (CM) contains secretomes that had shown immunomodulatory and tissue regenerative potential in pre-clinical and clinical studies. MSC-CM contains a cocktail of growth factors, cytokines, chemokines, enzymes, and exosomes, extracellular vesicles, etc. MSC-CM-based indirect treatment has the potential to eliminate the drawbacks of direct use of MSCs for periodontal tissue regeneration. MSC-CM holds the tremendous potential of bench-to-bed translation in periodontal regeneration applications. This review focuses on the accumulating evidence indicating the therapeutic potential of the MSC-CM in periodontal regeneration-related pre-clinical and clinical studies. Recent advances on MSC-CM-based periodontal regeneration, existing challenges, and prospects are well summarized as guidance to improve the effectiveness of MSC-CM on periodontal regeneration in clinics.

RESUMO

PURPOSE: To evaluate whether preoperative biopsy affects the outcomes of patients undergoing at least lobectomy for stage I lung adenocarcinoma. METHODS: We reviewed the medical records of patients who underwent surgery for stage I lung adenocarcinoma between 2006 and 2013. Tumor recurrence and survival were compared between patients who underwent preoperative biopsy, including computed tomographic-guided needle biopsy and transbronchial biopsy, and those who underwent intraoperative frozen section. RESULTS: Among 509 patients, 229 patients (44.9%) underwent preoperative biopsy and 280 patients had lung adenocarcinoma diagnosed by intraoperative frozen section (reference group). Recurrence developed in 65 (12.8%) patients within a median follow-up period of 54.4 months. Multivariate analysis demonstrated that preoperative biopsy (OR 1.97, p = 0.045), radiological solid appearance (OR 5.43, p < 0.001), and angiolymphatic invasion (OR 2.48, p = 0.010) were independent predictors of recurrence. In the overall cohort, preoperative biopsy appeared to worsen 5-year disease-free and overall survival significantly (76.6% vs. 93.0%, p < 0.001; and 83.8% vs. 94.5%, p = 0.002, respectively) compared with the reference group. After propensity matching, multivariable logistic regression still identified preoperative biopsy as an independent predictor of overall recurrence (OR 2.21, p = 0.048) after adjusting for tumor characteristics. CONCLUSION: Preoperative biopsy might be considered a prognosticator of recurrence of stage I adenocarcinoma of the lungs in patients who undergo at least anatomic lobectomy without postoperative adjuvant chemotherapy.

RESUMO

BACKGROUND: The benefits of neoadjuvant chemoradiation (NCRT) compared to upfront esophagectomy (UE) in esophageal squamous cell carcinoma (ESCC) is controversial. Our purpose was to determine whether clinical stages based on the 8th edition American Joint Committee on Cancer Tumor-Node-Metastasis staging system could guide treatment decision. METHODS: Data from 2503 patients with clinical stages II and III ESCC diagnosed between 2008 and 2014 were obtained from a nationwide database. Propensity score matching was used to identify well-balanced pairs of patients. Cox proportional hazards regression and log-rank test were used in the survival analysis. The outcomes of patients receiving "NCRT followed by surgery" or "UE" strategies were compared. RESULTS: The treatment modality (UE or NCRT) was not a prognostic factor in clinical stage II ESCC (HR: 0.97; p = 0.778). In contrast, the UE group demonstrated a significantly worse outcome compared with the NCRT group in clinical stage III ESCC (HR: 1.39; p < 0.001). After matching, patients who underwent UE for clinical stage II ESCC had median survival/3-year overall survival (OS) rates of 27.8 months/39.2% compared with 32.7 months/49.8% in the NCRT group (p = 0.508). The patients who underwent UE for clinical stage III ESCC had median survival/3-year OS rates of 17.9 months/28.2% in the UE group compared with 24.0 months/41.8% in the NCRT group (p < 0.001). CONCLUSIONS: Our data suggest that NCRT strategy improved survival compared with UE in clinical stage III ESCC but not in clinical stage II tumors.

RESUMO

BACKGROUND: Current esophageal treatment guidelines suggest that, when more than 15 lymph nodes are detected, dissection should be done as the minimum requirement for staging in esophageal squamous cell carcinoma (ESCC) patients undergoing esophagectomy without induction chemoradiotherapy (CRT). However, for neoadjuvant CRT, there is limited information. We sought to clarify the role of lymphadenectomy in ESCC patients with and without neoadjuvant CRT. PATIENTS AND METHODS: Data on 3156 ESCC patients receiving esophagectomy with (group 1, n = 1399) and without (group 2, n = 1757) neoadjuvant CRT between 2008 and 2014 were collected from a national cancer registry in Taiwan. The impact of the resected lymph nodes on overall survival was assessed according to pathologic stages. A Cox regression model was used to identify prognostic factors for overall survival. RESULTS: Five-year overall survival rates were 35.6% for the entire group, 30.32% for group 1, and 39.55% for group 2 (p < 0.0001 for group 1 vs group 2). The best cutoff value was 21 lymph nodes in both group 1 and group 2. In group 1, the independent prognostic factors included age ≥ 54 years, clinical N status, y-pathologic T, y-pathologic N, y-pathologic stage, grade, location, margin status, esophagectomy (thoracoscopic vs open), and number of total resected lymph nodes (≤ 21 vs > 21). For group 2, the independent prognostic factors were gender, clinical stage, pathologic T, pathologic N, tumor length, grade, and margin status. CONCLUSIONS: Extent of lymphadenectomy was associated with survival in patients with neoadjuvant CRT followed by esophagectomy. The optimum lymphadenectomy should be modulated by pathologic stage.

RESUMO

BACKGROUND: The current study aimed to establish a novel nomogram to predict the overall survival of individual Chinese patients with gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs). Furthermore, this study sought to externally validate this nomogram using the Surveillance, Epidemiology, and End Results (SEER) database. METHODS: The records of 1183 patients with GEP-NENs treated at five high-capacity institutions in China between 2005 and 2015 were retrospectively analysed. In addition, 10 236 GEP-NEN cases from the SEER database were included as an external validation set. RESULTS: A multivariate analysis using Cox proportional hazards (PHs) regression was performed, and a nomogram was constructed. Discrimination, calibration, and external validation were performed using the SEER data set. The multivariate Cox model indicated that age, tumour size, differentiation, lymph node metastases, and distant metastases were independent covariates associated with survival. With respect to the training set, the nomogram exhibited better discrimination power than TNM classification (Harrell's concordance index (C-index): 0.837 vs 0.784, P=0.006). Discrimination was also excellent and superior to that of TNM classification for the SEER-based validation set (C-index: 0.808 vs 0.717, P<0.001). The calibrated nomogram predicted a survival rate that closely corresponded to the actual survival rate. CONCLUSIONS: We developed a nomogram that predicted the 3- and 5-year overall survival rates of patients with GEP-NENs. Validation revealed excellent discrimination and calibration for this nomogram, suggesting that it exhibits satisfactory clinical utility that might improve individualised predictions of survival risks and lead to the creation of additional clinical therapies.

RESUMO

BACKGROUND: The clinicopathological characteristics of small intestinal neuroendocrine neoplasms (SI-NENs) and the prognostic validity of WHO grading classification for SI-NENs are still unknown in Asian patients. METHODS: 277 patients and 8315 patients with SI-NENs were retrieved respectively from eleven Chinese hospitals and Surveillance, Epidemiology, and End Results (SEER) cancer registry. Overall survival was used as the major study outcome. Survival analysis using Kaplan-Meier analysis with log-rank test and cox regression analysis were applied. RESULTS: Clinicopathological characteristics of SI-NENs were quite different among different races. Duodenum was the predominant tumor site in Chinese patients and Asian/Pacific Islander patients but not in white patients from SEER database. Patients with duodenal NENs tended to have more localized disease than patients with jejunal/ileal NENs which were confirmed by patients from SEER database. Grade 3 or poorly differentiated/undifferentiated tumor were more common and tumor size was significantly larger in ampullary NENs compared with that in non-ampullary duodenal NENs. As for the prognostic validity of WHO grading classification, survival between patients with grade 1 and grade 2 disease was not significantly different. Ki-67 index of 5% might be a better threshold between grade 1 and grade 2 than Ki-67 index of 2% in SI-NENs. CONCLUSIONS: Our study revealed that the clinicopathological characteristics of SI-NENs among different races were quite different. This might because duodenal NENs was much more common in Chinese patients and Asian/Pacific Islander patients. Duodenal NENs and jejunal/ileal NENs, ampullary and non-ampullary duodenal NENs shared different characteristics. Ki-67 index of 5% might be a better threshold between grade 1 and grade 2 in SI-NENs.

RESUMO

BACKGROUND: The role of adjuvant chemoradiation in esophageal cancer has been underestimated in the literature. This study was undertaken to determine whether adjuvant chemoradiation improves survival compared with surgery alone. METHODS: Data of 1095 esophageal squamous cell carcinoma (ESCC) patients, including 679 in surgery alone group (group 1) and 416 in surgery followed adjuvant chemoradaition group (group 2), were obtained from the Taiwan Cancer Registry database. Propensity score matching (PSM) analysis was used to identify 147 well-balanced patients in each group for overall survival comparison. RESULTS: After PSM, the 3-year survival rates and median survival were 44.9% and 27.2 (95% confidence interval [CI]: 17.6-40.3) months in group 2, which is significantly higher than that in group 1 (28.1% and 18.2 [95% CI: 14.3-24.5] months, P = 0.0043). In the multivariate survival analysis, pT3/4 stage (Hazard Ratio [HR]: 2.03, 95% CI: 1.38-2.97, P < 0.001), pN+ stage (HR: 1.83, 95% CI: 1.31-2.57, P = 0.0004), tumor length more than 32 mm (HR: 1.93, 95% CI: 1.33-2.79, P < 0.001), R1/2 resection (HR: 1.75, 95% CI: 1.15-2.66, P = 0.009), and adjuvant chemoradiation (HR: 0.57, 95% CI: 0.42-0.78, P < 0.0001) were independent prognostic factors. Subgroup analysis suggested patients with pT3/4 stage, pN+ stage tumors, larger tumor size, poorly differentiated tumors, and R1/2 resections were more likely to demonstrate survival benefit from adjuvant chemoradiation. CONCLUSIONS: Compared with surgery alone, adjuvant chemoradiation provides a survival benefit to ESCC patients, especially those with pT3/4 stage, N+ tumors, larger tumor size, poorly differentiated tumors, and R1/2 resections.

RESUMO

OBJECTIVE: To explore the clinical characteristics and genetic mutations in two children with Omenn syndromes. METHODS: Peripheral venous blood samples were collected from 2 children suspected with severe combined immunodeficiency (SCID) and their family members. The samples were subjected to RAG1 and RAG2 gene sequencing and TCR Vß subclone analysis. RESULTS: Both patients had recurrent infections, erythroderma rashes and alopecia baldness. One patient has fit with immunophenotype T-B-NK+, while another was consistent with typical Omenn syndrome combined with T+B-NK+ immunophenotype, IgE and eosinophil increase. Both children have carried compound heterozygous mutations of the RAG1 gene. The first patient carried c.1328 G>A (p.R443K) and c.2486-2490delGGAAA (p.R829fsX869) mutations, both were of de novel type. The second patient has carried c.1209C>T (p.R403W) and c.2892delT (p.ASN964LYSfs*14), with c.2892delT (p.ASN964LYSfs*14) being a de novel mutation. The parents of both patients were heterozygous carriers. The same mutations were not found in 100 healthy children. Both patients' 24 TCR Vß subfamilies have presented monoclonal or oligoclonal peaks, with TCR Vß polymorphism being severely disrupted. CONCLUSION: Three novel mutations have been identified in two children with Omenn syndrome, which featured early onset and rapid progression. Early recognition of the disease and prompt treatment may reduce the mortality.

RESUMO

Asthma is the result of chronic inflammation of the airways which subsequently results in airway hyper-responsiveness and airflow obstruction. It has been shown that an elicited expression of acidic mammalian chitinase (AMCase) may be involved in the pathogenesis of asthma. Our recent study has demonstrated that the specific suppression of elevated AMCase leads to reduced eosinophilia and Th2-mediated immune responses in an ovalbumin (OVA)-sensitized mouse model of allergic asthma. In the current study, we show that the elicited expression of AMCase in the lung tissues of both ovalbumin- and Der P2-induced allergic asthma mouse models. The effects of allergic mediated molecules on AMCase expression were evaluated by utilizing promoter assay in the lung cells. In fact, the exposure of chitin, a polymerized sugar and the fundamental component of the major allergen mite and several of the inflammatory mediators, showed significant enhancement on AMCase expression. Such obtained results contribute to the basis of developing a promising therapeutic strategy for asthma by silencing AMCase expression.

RESUMO

The prognostic value for the post-chemoradiation therapy (CRT) pathologic stage is uncertain. The purpose of this study was to compare the pathologic stage in patients undergoing esophagectomy with and without preoperative CRT for esophageal squamous cell carcinoma (ESCC). This study retrospectively reviewed the data from 2151 patients with ESCC who underwent esophagectomy with or without preoperative CRT between 2008 and 2011 in Taiwan. Patients were divided into 2 groups. Group A consisted of patients treated with primary surgery without prior treatments (n=1301), and group B consisted of patients receiving preoperative CRT followed by esophagectomy (n=850). In group A, 679 patients received surgery alone, 92 received postoperative chemotherapy, 416 received postoperative chemoradiation therapy, and 114 received postoperative radiation therapy. In group A, the 3-year survival rates by pathologic stage were 82.2% for stage 0, 67.6% for stage I, 50.7% for stage II, 21.5% for stage III, and 14.8% for stage IV (P<.001). In group B, the 3-year survival rates of post-CRT pathologic stages 0, I, II, III, and IV were 59.4%, 46.0%, 40.3%, 19.1%, and 8.2%, respectively (P<.001). In multivariate analysis, the pathologic T, N, and M were all independent prognostic factors in both group A (esophagectomy alone) and B (CRT plus esophagectomy). The current, 7th edition of the esophageal TNM staging system could adequately stratify prognostic groups in patients with squamous cell carcinoma who were treated with preoperative CRT and esophagectomy.

RESUMO

Due to the frequent detection and potential toxicity of moxifloxacin (MOX), its removal technology had attracted attention in recent years. In this research, CuFeS2/MXene was prepared and used to activate peroxymonosulfate (PMS) to remove MOX. The degradation efficiencies, kinetics, influences, and reaction mechanism of MOX by CuFeS2/MXene/PMS were investigated. The synergistic effect of CuFeS2 and MXene significantly enhanced PMS activation, producing SO4•-, HO•, and 1O2 as the main active species. By adding 0.12 g/L CuFeS2/MXene and 0.12 mM PMS, MOX removal efficiency reached 99.1% within 40 min, with a rate constant of 0.1073 min-1. The composite ratios of CuFeS2/MXene impacted PMS activation more significantly than catalyst dosages and PMS concentrations. Acidic conditions were favorable for the degradation of MOX, while HCO3-, HPO42-, Mn2+, and HA had the inhibitory effects. Twelve major products were detected by HPLC-MS, and DFT was used to illustrate possible degradation pathways of MOX, including the removal of nitrogen-containing heterocycle and transformations of quinolone moieties. Toxicity analysis showed that the developmental toxicity, mutagenicity, and acute toxicity of degradation products tended to decrease. CuFeS2/MXene could exhibit excellent reusability, maintaining an average MOX degradation efficiency of 90.8% in the 7-cycle experiments.

RESUMO

BACKGROUND: The interferon-gamma (IFN-γ) release assay (IGRA) is an important laboratory diagnosis for latent Mycobacterium tuberculosis (TB) infection. The TB-IGRA measures the release of IFN-γ from peripheral blood cells, who are exposed to TB antigen (Ag), mitogen (MT), or negative/nil control (NL) in vitro. While, an exceptional higher TB Ag-NL level will reflect an elevation of peripheral lymphocytes released IFN-γ in a same condition. Therefore, we found that the elevated levels of TB Ag-NL could become a new biomarker for the diagnosis and treatment of pediatric systemic lupus erythematosus (SLE) patients. METHODS: We have analyzed the clinical data of 776 children who are underwent TB-IGRA testing in the Department of Allergy and Rheumatology of Guangzhou Women and Children's Medical Center from 2018 to 2020. To investigate the association between TB Ag-NL and SLE, we have analyzed the clinical data of 47 SLE patients and TB Ag-NL testing results, and then evaluated the association between TB Ag-NL and SLE disease activity. RESULTS: The TB Ag-NL levels were significantly higher in patients with active SLE than those in inactive SLE (p = 0.0002). The TB Ag-NL levels were positively correlated with the SLE disease activity index (SLEDAI) and laboratory diagnosis parameters. The mean value of TB Ag-NL in SLE patients (0.04191 ± 0.07955, IU/mL) were significantly higher than those in patients with juvenile dermatomyositis (JDM) (0.0158 ± 0.0337, IU/mL, p = 0.036), juvenile idiopathic arthritis (JIA) (0.0162 ± 0.0388, IU/mL, p = 0.001), and healthy controls (HC) (0.0001 ± 0.0027, IU/mL, p = 0.0003). Therefore, the elevated TB Ag-NL levels could serve as a potential diagnostic biomarker of SLE, especially for the active SLE. CONCLUSION: The detection of IFN-γ release levels by the TB-IGRA may be useful to assess SLE disease activity in pediatric patients with active SLE.

RESUMO

BACKGROUND: To assess the effect of acupoint stimulation for Alcohol use disorders (AUD). METHODS: AUD is a complex disease that threatens the health of the global population. Acupoint stimulation, a sort of therapy applying stimulation on acupoints to produce a therapeutic effect without side effects, has been widely used in AUD patients, but its efficacy remains controversial. Electronic databases (the Cochrane Library, EMBASE, PubMed, CNKI, VIP, Wan-Fang) were systematically searched for randomized controlled trials (RCTs) on acupoint stimulation for AUD from database inception to September 30, 2022. A meta-analysis was performed using Review Manager 5.4 software. Continuous data (scales) were expressed as mean differences (MDs) or standardized mean difference (SMD) with 95% confidence intervals (95% CI). Study methodological quality was assessed according to the Cochrane risk-of-bias tool for trials. The grading of recommendations assessment, development and evaluation was used to assess the certainty of evidence for outcomes. RESULTS: A total of 16 RCTs with 1097 participants were included. Compared to psychotherapy or drug therapy alone, the combination of acupoint stimulation and other sorts of therapies presented advantages in alleviating alcohol craving (SMD = -1.09, 95% CI = -1.40 to -0.77, df = 2, P < .00001, grading of recommendations assessment, development and evaluation very low certainty), (SMD = -2.25, 95% CI = -3.17 to -1.34, df = 3, P < .00001, low certainty) and the severity of alcohol withdrawal symptoms (MD = -1.21, 95% CI = -2.32 to -0.1, df = 2, P = .03, low certainty), as well as improving anxiety (MD = -3.41, 95% CI = -4.06 to -2.76, df = 4, P < .00001, very low certainty) and depression levels (MD = -3.27, 95% CI = -4.92 to -1.62, df = 4, P = .0001, very low certainty) on patients with AUD. In addition, a greater effect was also found with the 4-week treatment courses in reducing craving (SMD = -2.18, 95% CI = -2.61 to -1.75, P < .00001, low certainty). CONCLUSION: Acupoint stimulation and its combined therapy may better relieve AUD symptoms effectively and the treatment duration should be set at more than 2 weeks. However, due to the low-quality of the included RCTs, high-quality studies are needed to further confirm it in the future.

RESUMO

We aimed to evaluate the role of esophagectomy in patients with esophageal squamous cell carcinoma with clinically complete response (cCR) after neoadjuvant chemoradiotherapy. Data of patients with locally advanced esophageal squamous cell carcinoma who achieved cCR after neoadjuvant chemoradiotherapy between October 2008 and September 2018 were retrospectively reviewed. The criteria for cCR include: (1) tumor resolution on computed tomography, (2) maximum standardized uptake value decrement >35% on positron-emission tomography-computed tomography scan, and (3) a negative endoscopic biopsy result. Overall survival (OS) and disease-free survival (DFS) were compared between patients who received surveillance only (surveillance) and those who underwent surgery. A total of 154 patients with cCR, including 54 in the surveillance group and 100 in the surgery group, were included. The 5-year OS rates in the surveillance and surgery groups were 47.9% and 36.9 %, respectively (P= 0.210). The 5-year DFS rates were 38.1% and 28.2%, respectively (P = 0.203). Surgery was not a prognostic factor in the multivariable analysis (OS: HR: 1.26, 95% CI: 0.69-2.33, P = 0.453; DFS: HR: 1.08, 95% CI: 0.60-1.96, P = 0.795). In the surgery group, ypT0N0, ypT+Nany, and ypT0N+ were noted in 54%, 37%, and 9% of patients, respectively. The 5-year OS rates were 55.8%, 22.2%, and 12.4%, respectively (P = 0.001). No survival differences were noted between the surveillance and surgery groups. However, 46% of cCR patients in the surgery group did not have pathological complete response, and their outcomes were poor. Esophagectomy may be the only way to identify patients with residual disease.

RESUMO

Reserve mesenchyme cells (RMCs) are a type of antler stem cells (ASCs) that contribute to the rapid growth of deer antlers, the only known mammalian organ that can fully regenerate annually. Based on the prior evidence, ASC-conditioned medium could improve regenerative cutaneous healing in rats. The purpose of the study was to evaluate the therapeutic effects of RMC-conditioned medium (RMC-CM) on reducing the destruction in the mice periodontitis (PD) model and the underlying mechanisms. The lipopolysaccharide (LPS)-stimulated RAW264.7 cells were used in vitro to verify the effects of RMC-CM. The results revealed that RMC-CM could significantly reduce bone resorption and osteoclast activation, upregulate anti-inflammatory macrophages (M2) related interleukin (IL)-10 and CD206, and downregulate pro-inflammatory macrophages (M1) related tumor necrosis factor alpha (TNF-α) and inducible nitric oxide synthase in vivo. In vitro, RMC-CM could significantly promote LPS-stimulated RAW264.7 cells migration, reduce osteoclast differentiation, downregulate the expression of TNF-α, IL-6, and IL-1ß, and upregulate the expression of IL-10 and arginase 1. According to the results, we concluded that RMC-CM could significantly reduce alveolar bone resorption and inhibit inflammation in gingival tissue by decreasing the activation of osteoclasts and inducing macrophage polarization toward the M2 phenotype. This study may serve as the experimental foundation for RMC-CM in the treatment of PD.

RESUMO

This study aimed to in the management of Kasabach-Merritt phenomenon (KMP), a severe thrombocytopenic coagulopathy that occurs in the presence of an enlarging vascular tumor. Here, we retrospectively evaluated 12 patients with KMP in Guangzhou Women and Children's Medical Center, Guangzhou Medical University, from 2017 to 2021. 12 patients, including 7 females and 5 males, were identified. Tumors were located in the leg (n = 4), neck (n = 1), face (n = 3), chest wall (n = 1), back (n = 2), and retroperitoneum (n = 1). A plaque-like lesion with ecchymosis was the most common cutaneous manifestation. All the patients underwent embolization therapy. Nine patients received steroid treatment and 7 patients were administered with sirolimus. The mean duration of treatment was 1.6 months. All the patients reported in this study were alive when discharged. Embolization combined with steroid and sirolimus appears effective in patients with KMP, as well as in those who experienced disease recurrence. However, a long-term follow-up of the children cured of KMP will be necessary to monitor its recurrence and improve the outcome.
