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.

Renal fibrosis （RF） is the primary pathological feature of chronic kidney disease （CKD） progression to end-stage renal disease （ESRD）， with glomerulosclerosis and tubulointerstitial fibrosis as core pathological manifestations. It involves abnormal accumulation of extracellular matrix （ECM） components such as collagen and fibronectin， ultimately leading to structural destruction and functional losses of the kidneys. Sirtuins （SIRTs）， a class of nicotinamide adenine dinucleotide （NAD+）-dependent deacetylases， play crucial roles in cellular metabolism， oxidative stress responses， inflammation regulation， and cell survival. In mammals， there are seven distinct SIRT members （SIRT1 to SIRT7）， which collectively ameliorate RF progression through multiple pathways. These include regulating the transforming growth factor （TGF）-β/Smad signaling pathway， suppressing inflammatory responses， reducing oxidative stress， modulating mitochondrial and autophagy functions， and promoting fatty acid oxidation. In recent years， traditional Chinese medicine （TCM） and its active components have demonstrated significant potential in activating or modulating the SIRT protease family and its regulatory networks to ameliorate RF in a multi-target and holistic manner. However， systematic reviews in this area remain lacking. This article elucidates the mechanisms by which the SIRT protease family regulates RF and reviews the latest research advances in TCM modulation of SIRTs for the prevention and treatment of RF， aiming to provide new insights and approaches for the TCM treatment of RF.

Objective To investigate the inhibition of gigantol on corneal neovascularization(CNV)in rats after corneal alkali burn.Methods Animal models of corneal alkali burn were made with SD rats,which were divided into normal control group,model control group,low-concentration gigantol group,high-concentration gigantol group and aflibercept group,with 10 rats in each group.The rats in low-concentration gigantol group,high-concentration gigantol group and aflibercept group were treated with 2.5 mg/0.05 mL gigantol,5 mg/0.05 mL gigantol,and 2 mg/0.05 mL aflibercept by subconjunctival injection after modeling.The CNV,corneal opacity score,and thickness of the cornea were observed and compared on the 3rd,7th,and 14th days after alkali burn.The ratio of CNV area to corneal area was calculated.On the 14th day,all rats were sacrificed.Hematoxylin and eosin staining and immunohistochemistry were used to detect the expression of CD34 and VEGF.The protein expression of VEGF,IL-1β,and TNF-α was detected by ELISA.Results On the 7th and 14th days after alkali burn,the percentages of CNV to total corneal area in low-concentration gigantol group,high-concentration gigantol group and aflibercept group were significantly smaller than those in model control group(all P＜0.05).On the 14th day,the corneal opacity score was lower in high-concentration gigantol group than model control group(P＜0.05).The corneal thickness in model control group and low-concentration gigantol group were significantly greater than that in normal control group(all P＜0.001).However,the corneal thickness in high-concentration gigantol group and aflibercept group were not significantly different from that in normal control group(all P＞0.05).In addition,the protein expression of VEGF,IL-1β,and TNF-α in corneal tissues in low-concentration gigantol group,high-concentration gigantol group and aflibercept group were significantly lower than that in model control group(all P＜0.01).Conclusions Gigantol administration by subconjunctival injection can inhibit the formation of CNV in rats after alkali burn and promote absorption of the corneal edema.

Objective To investigate the effect of pelvic floor muscle training based on timing theory in patients undergoing robot-assisted laparoscopic radical prostatectomy.Methods A total of 112 patients undergoing robot-assisted laparoscopic radical resection of prostate cancer in the First Affiliated Hospital of Fujian Medical University were selected as the study subjects from August 2021 to August 2022.57 patients in control group were given routine intervention measures,and 55 patients in experimental group were given pelvic floor muscle intervention based on timing theory on the basis of routine intervention measures.The intervention lasted for 1 year.The intervention effects of urinary control ability,urinary incontinence recovery rate and pelvic floor function rehabilitation were compared between two groups in each period after surgery.Results 24h after catheter removal,3 months and 6 months after the intervention,the experimental group had more advantages in urinary control score,urinary incontinence recovery rate and pelvic floor function recovery score(P＜0.05),but there was no statistical significance in the above aspects between the two groups at 12 months after the operation(P＞0.05).Conclusion The pelvic floor muscle training method based on the timing theory is scientific and feasible to a certain extent,and the intervention starts before surgery and lasts until 1 year after surgery,which significantly improves the postoperative urinary incontinence symptoms of patients with robot-assisted laparoscopic radical prostatectomy within the baseline level,improves the recovery rate of urinary incontinence,and helps the early rehabilitation of patients with postoperative urinary control ability.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Objective To evaluate the efficacy,safety and economy of centrally procured ceftazidime injection for treating pulmonary infections,and to provide a reference for clinical therapeutic decisions.Methods Based on the active monitoring and drug evaluation functions of the China Hospital Pharmacovigilance System(CHPS),a retrospective analysis was conducted.Electronic medical records of 203 patients treated with ceftazidime injection for pulmonary injections in our hospital from February 2021 to August 2022 were collected.Patients were divided into two groups based on the type of ceftazidime used,the centrally procured ceftazidime group(102 cases)and the non-centrally procured ceftazidime group(101 cases).Efficacy was evaluated by the effectiveness rate,safety by the incidence of adverse reactions,and economy by cost-effectiveness analysis.Differences between the two groups were compared.Results Treatment efficiency was 90.20%in the centrally procured group and 91.09%in the non-centrally procured group,with no statistically significant difference(P>0.05).The incidence of adverse reactions was 10.78%in the centrally procured group and 5.94%in the non-centrally procured group,with no statistically significant difference(P>0.05).The average cost-effectiveness ratio(C/E)was 1.56±0.86 in the centrally procured group and 18.96±9.38 in the non-centrally procured group,indicating a smaller C/E value for the centrally procured group.Sensitivity analysis results were consistent with the cost-effectiveness analysis results.Conclusion Centrally procured ceftazidime injection has equivalent efficacy and safety compared to non-centrally procured ceftazidime,with improved economic value.Therefore,the centrally procured variant should be given priority when using ceftazidime for the treatment of pulmonary infections.

Objective:To investigate the impact of single incision laparoscopic radical resection of colon cancer on postoperative quality of life and prognosis in patients with colon cancer.Methods:A prospective study was conducted on 84 colorectal cancer patients admitted to Suzhou Municipal Hospital between June 2019 and June 2022. The patients were divided into two groups of 42 each according to their wishes. The control group underwent traditional laparoscopic radical surgery for colon cancer; The observation group underwent single incision laparoscopic radical resection for colon cancer. Two sets of surgical related indicators, postoperative stress response, immune inflammatory response, tumor markers, complications, and prognosis were compared.Results:Compared with the control group, the observation group had less intraoperative bleeding [(142.58±23.76)ml vs (121.37±20.23)ml], faster recovery of intestinal function [(3.87±0.65)d vs (3.12±0.45)d], lower postoperative Visual Analog Scale (VAS) scores [(3.52±0.70)points vs (2.46±0.49)points], and a lower incidence of postoperative complications [26.19%(11/42) vs 7.14%(3/42)] (all P<0.05); There was no statistically significant difference in the surgical time, hospitalization time, and levels of carcinoembryonic antigen (CEA) and carbohydrate antigen (CA199) between the two groups (all P>0.05). The postoperative level of cortisol (Cor) [(473.25±52.58)nmol/L vs (447.53±49.73)nmol/L], adrenaline (E) [(662.41±73.60)μg/L vs (622.84±69.20)μ g/L], norepinephrine (NE) [(18.52±2.06)μ g/L vs (17.48±1.94)μ g/L], interleukin-6 (IL-6) [(51.24±5.26)pg/ml vs (47.33±5.26)pg/ml], high-sensitivity C-reactive protein (hs-CRP) [(21.47±3.58)ng/ml vs (19.26±3.26)ng/ml] of the observation group was lower than that of the control group (all P<0.05). The postoperative levels of CD3 + [(58.34±3.89) vs (60.21±4.01)] and CD4 + /CD8 + [(1.24±0.14) vs (1.31±0.15)] in the observation group were higher than those in the control group (all P<0.05). There was no statistically significant difference in the survival curve analysis between the two groups ( P>0.05). Conclusions:Both traditional conventional laparoscopic radical surgery and single incision laparoscopic radical surgery have good therapeutic effects on colorectal patients, which can effectively reduce tumor marker levels and have a good prognosis. However, single incision laparoscopic radical surgery has less stress damage to patients, can reduce immune inflammatory reactions, and has fewer postoperative complications, which can promote postoperative recovery.

Purpose To investigate the ultrasound features and classification of pilomatricoma and its correlation with pathological manifestations.Materials and Methods The clinical,ultrasound and pathological data of 76 patients(78 lesions)postoperative confirmed pilomatricoma in Henan Province Hospital of Traditional Chinese Medicine and the the First Affiliated Hospital of Henan University of Traditional Chinese Medicine from July 2014 to August 2021 were analyzed,retrospectively.According to the presence or absence of calcification and the pattern of calcification in the sonogram,they were divided into no calcification type,dotted calcification type,sheet calcification type and complete calcification type.Results Pilomatricoma were most common in children under 10,with predilection location in the face and head.Most lesions were surrounded by hypoechoic halo and calcification,51 of 78 lesions had different degrees of calcification,accounting for about 65.4%;36 lesions were with hypoechoic halo;63 lesions were mainly hypoechoic,accounting for about 80.8%.There were statistical differences in hypoechoic halo(χ2=15.624,P=0.001)and internal echo(χ2=12.801,P=0.021)among different classification pilomatricoma.Shadow cells and basicyte were detected in all 78 lesions,basophil cells were found in the periphery of 50 out of 54 lesions showing hypoechoic halos.The ultrasound manifestations of different types had characteristic changes corresponding to their pathological composition.Conclusion The ultrasound performance varies among the different types of pilomatricoma,and there is a correlation with its pathological changes.Familiarization with the sonographic presentation of pilomatricoma in the different types contributes to the preoperative diagnosis.

Purpose To explore the ability of proton density fat fraction(PDFF)and decay constant T2* values in MRI to reflect skeletal muscle aging.Materials and Methods 3T MRI data of skeletal muscle in the middle thigh of 211 healthy adults from the Third Affiliated Hospital of Southern Medical University from August to December 2023 were prospectively collected.Gender,age,height,weight and body mass index(BMI)were recorded.PDFF value and T2* value of thigh skeletal muscle were measured at post-processing workstation,and statistical differences among different age,gender and BMI groups were analyzed.The correlation between PDFF value and T2* value of thigh skeletal muscle and age and BMI was analyzed.Results There were statistically significant differences in PDFF values of thigh skeletal muscle among different age groups(H=18.476-85.619,all P<0.01).There were significantly differences in T2*values of the left and right quadriceps muscles,hamstrings and adductors among different age groups(H=13.342-47.566,all P<0.05).There were statistically significant differences in the PDFF values of right quadriceps,left and right hamstring,adductor and sartor muscles between male and female groups(Z=-4.929--1.626,all P<0.05),while there were statistically significant differences in T2* values of left sartor muscle(Z=-2.971,P=0.003).There was no statistical significance in PDFF value of skeletal muscle of thigh in different BMI groups(P>0.05),but there were statistically significant differences in T2* value of left and right quadriceps muscle,hamstring muscle and adductor muscle(H=9.542-24.495,all P<0.05).There was a moderate positive correlation between age and PDFF value of thigh skeletal muscle(r=0.635,P<0.01),but a slight negative correlation with T2* value of left and right quadriceps,hamstring and sarcoleus(r=-0.451--0.189,all P<0.01).There was a slight positive correlation between BMI and T2* values of thigh skeletal muscle(r=0.317,P<0.01).There was a moderate negative correlation between the PDFF value and T2* value of all thigh skeletal muscles(r=-0.749--0.624,P<0.01).The PDFF and T2* values of the front and back thigh muscles(quadriceps,hamstring)were most significantly correlated with age and BMI.Conclusion PDFF based on MRI can reflect the age-related changes in the microenvironment of thigh skeletal muscle,and is a potential imaging biological marker for accurate and non-invasive quantitative evaluation of thigh skeletal muscle aging.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.
