Objective To systematically evaluate the risk prediction model of anastomotic fistula after radical resection of esophageal cancer, and to provide objective basis for selecting a suitable model. Methods A comprehensive search was conducted on Chinese and English databases including CNKI, Wanfang, VIP, CBM, PubMed, EMbase, Web of Science, The Cochrane Library for relevant studies on the risk prediction model of anastomotic fistula after radical resection of esophageal cancer from inception to April 30, 2023. Two researchers independently screened literatures and extracted data information. PROBAST tool was used to assess the risk of bias and applicability of included literatures. Meta-analysis was performed on the predictive value of common predictors in the model with RevMan 5.3 software. Results A total of 18 studies were included, including 11 Chinese literatures and 7 English literatures. The area under the curve (AUC) of the prediction models ranged from 0.68 to 0.954, and the AUC of 10 models was >0.8, indicating that the prediction performance was good, but the risk of bias in the included studies was high, mainly in the field of research design and data analysis. The results of the meta-analysis on common predictors showed that age, history of hypertension, history of diabetes, C-reactive protein, history of preoperative chemotherapy, hypoproteinemia, peripheral vascular disease, pulmonary infection, and calcification of gastric omental vascular branches are effective predictors for the occurrence of anastomotic leakage after radical surgery for esophageal cancer (P<0.05). Conclusion The study on the risk prediction model of anastomotic fistula after radical resection of esophageal cancer is still in the development stage. Future studies can refer to the common predictors summarized by this study, and select appropriate methods to develop and verify the anastomotic fistula prediction model in combination with clinical practice, so as to provide targeted preventive measures for patients with high-risk anastomotic fistula as soon as possible.

Objective:To investigate the application value of shear wave elastography (SWE) in the evaluation of T re-staging after neoadjuvant chemoradiotherapy (nCRT) for locally advanced rectal cancer.Methods:Clinical, endorectal ultrasound (ERUS) and SWE data of 271 patients with locally advanced rectal cancer who underwent nCRT and total mesorectal excision in Fujian Medical University Union Hospital from October 2021 to March 2023 were prospectively collected. The independent predictors for low T staging were analyzed and screened, and the Logistic regression model was constructed. An independent test set was used to validate the prediction performance of the models and compare them with the diagnostic results of sonographers.Results:Binary multivariate Logistic regression analysis showed that Emean of the mesentery around the lesion, thickness, and enlarged lymph nodes around the rectum were the independent predictors for low T staging, and the odds ratios were 1.089, 1.214, 0.183, respectively. The Logistic regression model A established by Emean, thickness and enlarged lymph nodes around the lesion and the Logistic regression model B established by Emean around the lesion had high diagnostic efficiencies (area under the ROC curve were 0.931, 0.918, respectively, the accuracy were 0.888 and 0.887, respectively). There was no significant difference in diagnostic accuracy between the two models ( P=1.000), and both models were significantly higher than that of sonographers (all P<0.001). Conclusions:SWE can effectively predict whether the tumor is of low T staging after nCRT in locally advanced rectal cancer, and can be used as an important supplement to ERUS in evaluating the T re-staging of rectal cancer after nCRT.

As a new strategy for the application of sacubitril/valsartan (LCZ696) in patients with CKD, much evidence showed that it improved the prognosis of patients with CKD. This review summarizes the efficacy and safety of sacubitril/valsartan in physiology, pathology, pharmacology and clinical application by searching Wanfang, CNKI, PubMed and other databases for related articles on the application of sacubitril/valsartan in CKD patients. Although LBQ657, the active product of sacubitril, has a high drug accumulation in patients with moderate, severe renal injury, and ESRD, it is not cleared in hemodialysis, and has very little eliminated in peritoneal dialysis, which does not affect its safety. Compared with angiotensin converting enzyme inhibitor and angiotensin receptor blocker drugs, LCZ696 could increase the blood pressure control rate, improve cardiac function, slow down the decline of glomerular filtration rate, and significantly improve cardiovascular outcomes without more adverse events. Sacubitril/valsartan can be used in all levels of CKD patients complicated with hypertension and/or heart failure, with reliable safety and tolerance.

JAK-STAT signaling pathway is an important cytokine signaling transduction pathway. Many monogenic loss-of-function or gain-of-function mutations in this pathway can cause inborn errors of immunity (IEI). Autoimmune diseases are caused by polygenic and different factors.The etiology of the disease is complex and diverse. The over-activation of JAK-STAT signaling pathway plays a significant role in the pathogenesis of autoimmune diseases. In this article, we summarize the mechanism of the JAK-STAT pathway and its role in the occurrence and development of IEI and autoimmune diseases, suggesting that the hyperactivation of JAK-STAT pathway having connection with IEI and autoimmune diseases. Meanwhile, we hope to make IEI a good model to study the pathogenesis of autoimmune diseases and to provide new ideas and directions for the clinical treatment of autoimmune diseases.

Objective Air pollution is a leading public health issue.This study investigated the effect of air quality and pollutants on pulmonary function and inflammation in patients with asthma in Shanghai. Methods The study monitored 27 asthma outpatients for a year,collecting data on weather,patient self-management[daily asthma diary,peak expiratory flow(PEF)monitoring,medication usage],spirometry and serum markers.To explore the potential mechanisms of any effects,asthmatic mice induced by ovalbumin(OVA)were exposed to PM2.5. Results Statistical and correlational analyses revealed that air pollutants have both acute and chronic effects on asthma.Acute exposure showed a correlation between PEF and levels of ozone(O3)and nitrogen dioxide(NO2).Chronic exposure indicated that interleukin-5(IL-5)and interleukin-13(IL-13)levels correlated with PM2.5 and PM10 concentrations.In asthmatic mouse models,exposure to PM2.5 increased cytokine levels and worsened lung function.Additionally,PM2.5 exposure inhibited cell proliferation by blocking the NF-κB and ERK phosphorylation pathways. Conclusion Ambient air pollutants exacerbate asthma by worsening lung function and enhancing Th2-mediated inflammation.Specifically,PM2.5 significantly contributes to these adverse effects.Further research is needed to elucidate the mechanisms by which PM2.5 impacts asthma.

Objective To compare the differences in efficacy and safety between transarterial chemoembolization(TACE)com-bined with lenvatinib and camrelizumab(triple therapy)and TACE combined with lenvatinib(double therapy)in intermediate or advanced stage hepatocellular carcinoma(HCC).Methods The clinical data of 145 patients who were diagnosed with HCC and received triple therapy or double therapy were retrospectively collected.The differences of objective response rate(ORR),disease control rate(DCR),median progression-free survival(mPFS),median overall survival(mOS),and adverse events were compared between the two groups.Results The ORR and DCR in 1,3 and 6 months of the triple therapy group were higher than those of the double therapy group,and the differences were statistically significant in 3 and 6 months.The mPFS and mOS of the triple therapy group were higher than those of the double therapy group,and the differences were statistically significant.The Cox proportional hazards model results showed that the therapy methods,maximum tumor diameter and alpha-fetoprotein(AFP)were independent risk factors of progres-sion-free survival(PFS)and overall survival(OS).Besides,Barcelona Clinic Liver Cancer(BCLC)staging was independent risk fac-tor of OS.In terms of adverse events,the incidence of reactive cutaneous capillary endothelial proliferation(RCCEP)and hypothy-roidism in the triple therapy group were higher than those in the double therapy group,and the differences were statistically signifi-cant.Conclusion Compared with double therapy,triple therapy can significantly improve the efficacy of intermediate or advanced stage HCC,prolong patients'PFS and OS,and its safety can be well controlled.

Objective:To prospectively observe the changes of tumor-related symptoms in patients with nasopharyngeal carcinoma following the administration of nimotuzumab one week before radiotherapy.Methods:Non-metastatic nasopharyngeal carcinoma patients with positive epidermal growth factor receptor (EGFR) expression and symptoms caused by the primary lesion or metastatic cervical lymph nodes admitted to Cancer Hospital of Chinese Academy of Medical Sciences were prospectively recruited. Investigators recorded tumor-related symptoms in recruited patients one day before the first administration of nimotuzumab (D0) and conducted follow-up visits from day 2 to day 7 after the first administration (D2-D7) to document symptom changes. All recruited patients were asked to assess tumor-related symptoms on D0 and D7 by visual analogue scale (VAS) scores. VAS scores were analyzed by paired t-test. Results:From June 2020 to April 2023, a total of 21 patients met the inclusion criteria. The median age was 49 years (range: 27-69 years), with a male-to-female ratio of 1.3:1. Among the patients, 17 patients (81%) received concurrent nimotuzumab for 8 cycles, 7 cycles for 3 cases (14%), and 6 cycles for 1 case (5%), respectively. All patients completed symptom assessments as required. The overall response rate of symptoms after the first administration of nimotuzumab was 62%, with response rates of 4/6、5/8、4/10、4/10、4/11、3/11 for tinnitus, headache, aural fullness, secondary pain caused by neck mass, nasal bleeding, and nasal obstruction, respectively. The VAS scores for overall symptoms were significantly decreased after the administration of nimotuzumab one week before radiotherapy ( P<0.001), with the most significant decrease in VAS scores for tinnitus, aural fullness, and headache. Conclusion:The administration of nimotuzumab one week before radiotherapy significantly alleviates tumor-related symptoms in patients with nasopharyngeal carcinoma, particularly in alleviating tinnitus, aural fullness, and headache.

Objective:To develop a set of lowest instrumented vertebra (LIV) selection criteria for adolescent idiopathic scoliosis (AIS) with Lenke 1A curves named as "Gulou Rule", and compared with the traditional "last substantially touching vertebra (LSTV) Rule".Methods:Based on our previous retrospective studies about LIV selection, as well as our clinical experience, the key parameters associated with LIV selection were found out and quantified to form the "Gulou Rule". A prospective consecutive collection of 189 Lenke 1A cases (male 29 cases, female 160 cases) who underwent posterior spinal fusion surgery in our clinic from January 2021 to January 2022 were recruited, with an average age of 14.9±2.8 (range 10-18) years old. They were divided into 2 groups according to the enrollment number (odd or even number). Patients with odd numbers were guided by the "LSTV Rule",while those with even numbers followed the "Gulou Rule" for the selection of LIV. The duration of follow-up was at least two years. Radiographical parameters were measured preoperatively, immediately postoperatively, and at the final follow-up, including numbers of fused segments, Cobb angle of proximal thoracic curve, main thoracic curve and lumbar curve, correction rate, coronal and sagittal balance parameters. The incidence of distal adding-on at the last follow-up was recorded.Results:The "Gulou Rule" was defined as follows: when Risser ≥3, main curve length ≤8 segments, one level proximal to LSTV (LSTV-1) rotation ≤ I degree, LSTV-1 deviation from the CSVL <20 mm, preoperative coronal balance <10 mm, and the intervertebral disc between LSTV-1 and LSTV opens bidirectionally on bending films, the LIV can be selected as LSTV-1; if these conditions are not met, LIV should be selected as LSTV. At last, 120 patients (male 21 cases, female 99 cases) were enrolled in the study with at least a 2-year follow-up, with an average age of 15.1±2.4 (range 10-18) years old. Each group had 60 patients, and the average duration of follow-up was 31.0±5.4 months for the "LSTV Rule" group and 30.8±5.1 months for the "Gulou Rule" group. The LIV in the "Gulou Rule" group was on average at the T 12 and L 1 level, where as in the "LSTV Rule" group, it was at the L 1 and L 2 level ( P=0.004). The "LSTV Rule" group had an average fused segments of 10.5±1.7, while the "Gulou Rule" group was significantly lower with 9.7±1.5 segments ( t=2.760, P=0.003). At the last follow-up, the main curve correction rates were 74.8%±10.5% and 73.2%±12.3%, respectively, with no significant difference ( t=0.779, P=0.219). The incidence of distal adding-on phenomenon was 15% in the "LSTV Rule" group and 17% in the "Gulou Rule" group, with no significant difference between the two groups (χ 2=0.063, P=0.803). Conclusion:For Lenke 1A AIS patients, both the "Gulou Rule" and the "LSTV Rule" for guiding LIV selection can achieve satisfactory correction outcomes. Choosing LIV based on the "Gulou Rule" allows for the preservation of distal fusion segments and demonstrates better clinical applicability.

Objective:To evaluate the effects of biorhythm factors on the occurrence of acute kidney injury (AKI) after cardiac surgery using cardiopulmonary bypass.Methods:This was a retrospective cohort study. Data from patients undergoing heart surgery involving cardiopulmonary bypass from June 2018 to December 2019 were collected and divided into 2 groups ( n=125 each) based on the time of anesthesia operation: morning rhythm group (group Ⅰ) and afternoon rhythm group (group Ⅱ). Anesthesia operation was performed from 8: 00 to 12: 00 in group Ⅰ. Anesthesia was performed from 14: 00 to 18: 00 in group Ⅱ. The occurrence of postoperative AKI and other postoperative complications (pulmonary infection, sepsis, cerebral infarction) was recorded. Results:Compared with group Ⅱ, the incidence of postoperative AKI was significantly increased, the relative risk was 3.2 (95% confidence interval 1.31-7.70), and no significant change was found in the incidence of pulmonary infection, sepsis and cerebral infarction in group Ⅰ ( P>0.05). Conclusions:Biorhythm factors affect the development of AKI after cardiac surgery using cardiopulmonary bypass, and performing surgeries in the afternoon rather than the morning helps reduce the risk of postoperative AKI.

Objective:To evaluate the relationship between the mechanism of curcumin attenuating lidocaine-induced neurotoxicity and autophagy.Methods:In vitro human neuroblastoma SH-SY5Y cells at the logarithmic phase were divided into 3 groups ( n=12 each) using the random number table method: blank control group (C group), lidocaine group (Lid group), and curcumin + lidocaine group (Cur + Lid group). The cells were incubated with complete medium containing 1.0 μmol/L curcumin for 24 h, and the other groups were incubated with fresh medium for 24 h under the same conditions in Cur+ Lid group. Then the medium was incubated with the complete medium containing 4.0 mmol/L lidocaine for 24 h in Lid and Cur+ Lid groups, and the medium was replaced with the fresh medium and the cells were incubated for 24 h under the same conditions in group C. At the end of incubation or culture, the cell viability was detected by CCK-8 method, the level of autophagosomes was detected by the MDC method, and the expression of P62, microtubule-associated protein light chain 3-Ⅱ (LC3-Ⅱ) and LC3-Ⅰ was detected by Western blot, and the LC3-Ⅱ/LC3-Ⅰ ratio was calculated. Results:Compared with group C, the cell viability was significantly decreased, the level of autophagosomes was increased, the expression of LC3-Ⅱ was up-regulated, the expression of LC3-Ⅰ was down-regulated, the LC3-Ⅱ/LC3-Ⅰ ratio was increased, and the expression of P62 was down-regulated in Lid and Cur+ Lid groups ( P<0.05). Compared with Lid group, the cell viability and level of autophagosome were significantly increased, the expression of LC3-Ⅱ was up-regulated, the expression of LC3-Ⅰ was down-regulated, the LC3-Ⅱ/LC3-Ⅰ ratio was increased, and the expression of P62 was down-regulated in Cur+ Lid group ( P<0.05). Conclusions:The mechanism by which curcumin reduces the neurotoxicity induced by lidocaine may be related to the activation of autophagy.
