Objective To investigate the risk factors associated with the presence of multiple Lugol-voiding lesions(LVLs)in patients with early esophageal cancer and the correlation with alcohol dehy-drogenase 1B(ADH1B)and aldehyde dehydrogenase 2(ALDH2)polymorphisms.Methods Patients who underwent endoscopic submucosal dissection due to early esophageal cancer were divided into group with multiple LVLs and group without multiple LVLs based on their endoscopic features.Their clinical data and the genotype of ADH1B and ALDH2 were collect-ed and SPSS 27.0 was used to statistically analyze the above data.Results A total of 83 subjects were included in the study,23 had multiple LVLs,most of them were seen in males,alcohol drinkers,and smokers with smoking index≥1 000,and multivariate analysis showed that alcohol consumption was an independent risk factor for it(OR=6.215,P=0.008).The gene polymorphism of ADH1B and ALDH2 and their interactions did not have any sig-nificant correlation with multiple LVLs.However,among alcohol drinkers,there was a 12-fold increased risk of multiple LVLs in patients carrying the ALDH2 A allele and drinking≥50 g per day compared to those carrying the ALDH2 GG genotype and drinking<50 g per day(P=0.045).Conclusion Alcohol consumption is an inde-pendent risk factor of multiple LVLs of the esophageal mucosa in patients with early esophageal cancer,and heavy alcohol consumption in carriers of the ALDH2 A allele will significantly increase the risk of multiple LVLs,and such patients should be closely followed up with endoscopy.

Background:Combined double-balloon enteroscopy(DBE)plays an important role in the diagnosis and treatment of patients with suspected small bowel bleeding(SSBB).Aims:To investigate the performance of combined DBE in patients with SSBB and their clinical features.Methods:A total of 94 patients with SSBB underwent combined DBE from June 2018 to April 2023 at the Third People's Hospital of Bengbu and the First Affiliated Hospital of Anhui Medical University were enrolled,and the clinical features were analyzed.Results:Fifty-four SSBB patients completed the combined DBE,and the combination rate was 57.4%.Ten patients(10.6%)stopped combined DBE due to discovery of bleeding lesions.Five patients(5.3%)stopped combined DBE due to intestinal stenosis.Twenty-five patients(26.5%)stopped combined DBE due to difficulty in insertion.Combined DBE rate in SSBB patients was correlated with the combination time and the number of previous DBE for endoscopists(P<0.05),but not the gender,age,bleeding manifestations,tobacco smoking and alcohol drinking,nutritional risk,abdominal operation history,perianal lesions,autoimmune diseases,preoperative anemia,preoperative albumin level,and enteroscopy approach(P>0.05).ROC curve showed that when the cut-off value of first insertion depth was 385 cm,the sensitivity and specificity for successful combined DBE in SSBB patients were 72.2%and 77.5%,respectively,and the area under ROC curve was 0.800(95%CI:0.705-0.875,P<0.001).Conclusions:The combined DBE rate in SSBB patients is correlated with the combination time and the number of previous DBE for endoscopists.80%of the SSBB patients are expected to complete the combined DBE when the first insertion depth is greater than 385 cm.

Objective : To compare the diagnostic efficacy of three screening methods，including the epidemiological survey and the new gastric cancer scoring system proposed in the Expert Consensus Opinion on Early Gastric Cancer Screening Process in China ( Shanghai，2017) ，and the Kyoto classification score for screening gastric in early gastric cancer diagnosis． Methods: Patients who underwent endoscopic submucosal dissection and were pathologically confirmed were included in the gastric cancer group，patients with non-gastric cancer in the same period were consecutively included in the control group．Questionnaires and serological tests were performed in all enrolled patients，and the endoscopic presentations was recorded according to the classification of Kyoto gastritis during gastroscopy．The risk stratification and the detection rates of gastric cancer were estimated by different screening methods，and the receiver operating characteristic curve (ROC curve) of subjects diagnosed with each screening method alone and in combination were plotted to compare the area under the ROC curve (AUC) and the diagnostic efficacy . Results: Among all participants，84 were patients with gastric cancer and 120 were normal people without gastric cancer．The Kyoto risk score had the highest diagnostic value (AUC = 0. 79) among the others，and its sensitivity and specificity were 72. 6% and 79. 1% ，respectively，but the combined diagnosis of different methods did not significantly improve the diagnostic efficacy．The Kyoto risk score had a more discriminative value in the medium to high-risk group delineated by the new scoring system． Conclusion The Kyoto risk score has high clinical value in the diagnosis of early gastric cancer and can be used in conjunction with the new scoring system for early gastric cancer risk assessment.

Objective:To explore the outcome of sponge forceps assisted threading with Speedbridge technique for the treatment of acute closed Achilles tendon rupture.Methods:A retrospective case series study was conducted on 20 patients with acute closed Achilles tendon rupture treated in Zhengzhou Orthopedic Hospital from December 2019 to December 2021. There were 18 males and 2 females, with age range of 24-43 years [(29.5±7.6)years]. All patients were with unilateral injury, involving the left side in 13 patients and right side in 7. Examinations revealed a palpable defect in the Achilles tendon and positive Thompson test. A longitudinal incision was made at the medial edge of the ruptured tendon. Three nonabsorbable sutures were passed through the proximal stump with sponge forceps, bypassed the rupture site and fixed directly into the calcaneal bone. The disrupted tendon ends were aligned by the tendon-bundle technique using 4-0 absorbable sutures. The operation time and incision length were documented. The ankle joint range of motion (dorsiflexion/plantar flexion), American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and Achilles tendon total rupture score (ATRS) in the affected and healthy side were compared at 3, 6 and 12 months postoperatively. The wound healing and complications were observed.Results:All patients were followed up for 12-16 months [(13.2±2.5)months]. The operation time was 40-66 minutes [(52.0±10.3)minutes], with the incision length of 3-4 cm [(3.3±0.7)cm]. In the affected side at 3 and 6 months postoperatively, the ankle joint dorsiflexion [(5.6±1.5)°, (10.5±0.2)°] and plantar flexion [(28.4±3.2)°, (33.5±1.5)°] showed statistically significant difference compared with the healthy side (all P<0.05). The ankle joint dorsiflexion [(13.9±0.7)°] and plantar flexion [(38.3±4.4)°] in the affected side were not statistically different from that of the healthy side at 12 months postoperatively (all P>0.05). The AOFAS ankle-hindfoot score was (58.3±5.4)points, (84.9±7.1)points and (91.8±6.3)points at 3, 6 and 12 months postoperatively, showing a gradual rise (all P<0.05). The ATRS was (60.5±4.9)points, (85.5±9.0)points and (93.1±5.7)points at 3, 6 and 12 months postoperatively, showing a gradual rise (all P<0.05). All incisions were healed primarily. No patients had wound infection, nerve injury or re-rupture. Pain at the anchor insertion site occurred in 2 patients at 1 month after operation and relieved after active functional rehabilitation at 4 months after operation. Transient pain at the Achilles tendon insertion occurred in 1 patient at 6 months after operation, and relieved after 2 weeks of oral non-steroidal anti-inflammatory drugs treatment. Conclusion:For acute closed Achilles tendon rupture, sponge forceps assisted threading with Speedbridge technique can attain short operation time, small incision and good functional recovery, with few complications.

OBJECTIVE To investigate the awareness of the patients receiving Sanjin tablets in knowledge-attitude-practice （KAP） aspect， and its influential factors. METHODS Demographic characteristics， medication knowledge， attitude and practice of outpatients and inpatients who used Sanjin tablets in the First Affiliated Hospital of Henan University of Traditional Chinese Medicine from June to December 2020 were investigated online and offline for questionnaire survey and scale scoring.Oneway variance analysis and multiple linear regression analysis were used to screen the influential factors for KAP of the patient receiving Sanjin tablets. RESULTS A total of 503 valid questionnaires （effective recovery rate of 99.60%） were collected in this survey. The drug use knowledge score of Sanjin tablet users was （26.74±6.82） points， the drug use attitude score was （7.82±3.75） points， and the drug use practice score was （21.72±5.56） points. The overall scores were good， excellent and good， respectively.The results of oneway variance analysis showed that there were significant differences in drug use knowledge and drug use practice scores among the patients receiving Sanjin tablets with different ages，occupations and medical insurance types （P＜0.05）； there were significant differences in drug use attitude scores among the patients receiving Sanjin tablets with different ages， occupations， education levels and medical insurance types （P＜0.05）. The results of multiple linear regression analysis showed that ages， occupations， education levels and medical insurance types were the main factors affecting the drug use knowledge and drug use attitude of the patients receiving Sanjin tablets （P＜0.05）； education levels and medical insurance types were the main factors affecting the drug use practice of the patients receiving Sanjin tablets （P＜0.05）. CONCLUSIONS Most of the patients receiving Sanjin tablets have a good attitude towards the acquisition of safe medication information， but the knowledge to drug use and the actual drug use practice still have certain hidden danger in security； it is necessary to strengthen drug use education and publicity for individual age groups， low-educational background groups and other people， carry out the drug education among the population with different vocational characteristics and medical insurance types in order to promote safe and rational drug use.

Objective:To investigate whether FcγRⅡb rs775 single nucleotide polymorphism confers susceptibility to Hashimoto′s thyroiditis and its impact on expression of FcγRⅡb protein on B cell surface.Methods:A total of 187 Hashimoto′s thyroiditis patients(HT group) were enrolled, including 46 males(24.60%) and 141 females(75.40%), with a median age of 43(32, 53) years, and 187 healthy controls(conrol group), including 62 males(33.16%) and 125 females(66.84%), with a median age of 41(31, 51) years. The peripheral blood of two groups were sequenced, genotype and allele frequencies distribution of FcγRⅡb rs775 T>C were compared with clinical parameters as strata between the two groups. At the same time, the expression of inhibitory receptor FcγRⅡb on B cell surface was detected using flow cytometry.Results:Compared with control group, the mutant homozygous CC genotype was obviously enrichment in HT group( OR=3.321, 95% CI 1.175-9.386, P=0.018), and the proportion of CC genotype increased in male of HT group( P=0.076). However, there is no significant difference in genotype and allele frequencies between control group and HT group after stratification by sex. In addition, the percentage of FcγRⅡb on B cell surface decreased significantly in HT group( P=0.029). Conclusion:There was no significant correlation between FcγRⅡb polymorphism and the down-regulation of FcγRⅡb protein on B cell surface in Hashimoto′s thyroiditis patients, and FcγRⅡb can be a predisposed factor for Hashimoto′s thyroiditis.

Objective: To investigate the correlation between clinicopathologic features like human epidermal growth factor receptor type 2(HER2) status and lymph node metastasis, meanwhile, to establish a prediction model for the risk of lymph node metastasis in early gastric cancer. Methods: Multiple data of 157 patients who underwent early gastric cancer radical gastrectomy were involved and analyzed. Further, the risk prediction model was established for lymph node metastasis of early gastric cancer. Results: Among these 157 patients, 31 cases were reported lymph node metastasis, with a rate of 19.7%. Analysis showed that female patients, HER2 IHC(3+), infiltrating into submucosa, poor degree of differentiation and vascular invasion accounted for a large proportion in lymph node metastasis(P<0.05). Analysis also showed that HER2 IHC(3+), infiltrating into submucosa, poor degree of differentiation and vascular invasion were independent risk factors for lymph node metastasis in early gastric cancer(P<0.05). According to the above analysis results, the prediction models for lymph node metastasis risk of early gastric cancer were established respectively included or excluded HER2 status, and the area under the ROC curve(AUC) was 0.800 and 0.759, respectively. Meanwhile, differentiated tumor accounted for a large proportion in HER2 IHC(3+)(P<0.05). Conclusion HER2 IHC(3+), infiltrating into submucosa, poor degree of differentiation and vascular invasion were independent risk factors of lymph node metastasis in early gastric cancer. The new established model including HER2 status has good sensitivity and specificity, which may provide a reference for predicting the risk of lymph node metastasis in early gastric cancer.

Medulloblastoma (MB) is a common yet highly heterogeneous childhood malignant brain tumor, however, clinically effective molecular targeted therapy is lacking. Modulation of hedgehog (HH) signaling by epigenetically targeting the transcriptional factors GLI through bromodomain-containing protein 4 (BRD4) has recently spurred new interest as potential treatment of HH-driven MB. Through screening of current clinical BRD4 inhibitors for their inhibitory potency against glioma-associated oncogene homolog (GLI) protein, the BRD4 inhibitor

Objective: To investigate the feasibility and the accuracy of the coronary CT angiography (CCTA)-derived Registry of Crossboss and Hybrid procedures in France, the Netherlands, Belgium and United Kingdom (RECHARGE) score (RECHARGE CCTA) for the prediction of procedural success and 30-minutes guidewire crossing in percutaneous coronary intervention (PCI) for chronic total occlusion (CTO). Materials and Methods: One hundred and twenty-four consecutive patients (mean age, 54 years; 79% male) with 131 CTO lesions who underwent CCTA before catheter angiography (CA) with CTO-PCI were retrospectively enrolled in this study. The RECHARGE CCTA scores were calculated and compared with RECHARGECA and other CTA-based prediction scores, including Multicenter CTO Registry of Japan (J-CTO), CT Registry of CTO Revascularisation (CT-RECTOR), and Korean Multicenter CTO CT Registry (KCCT) scores. Results: The procedural success rate of the CTO-PCI procedures was 72%, and 61% of cases achieved the 30-minutes wire crossing. No significant difference was observed between the RECHARGE CCTA score and the RECHARGECA score for procedural success (median 2 vs. median 2, p = 0.084). However, the RECHARGE CCTA score was higher than the RECHARGE CA score for the 30-minutes wire crossing (median 2 vs. median 1.5, p = 0.001). The areas under the curve (AUCs) of the RECHARGE CCTA and RECHARGE CA scores for predicting procedural success showed no statistical significance (0.718 vs. 0.757, p = 0.655). The sensitivity, specificity, positive predictive value, and the negative predictive value of the RECHARGE CCTA scores of ≤ 2 for predictive procedural success were 78%, 60%, 43%, and 87%, respectively. The RECHARGE CCTA score showed a discriminative performance that was comparable to those of the other CTA-based prediction scores (AUC = 0.718 vs. 0.665–0.717, all p > 0.05). Conclusion The non-invasive RECHARGE CCTA score performs better than the invasive determination for the prediction of the 30-minutes wire crossing of CTO-PCI. However, the RECHARGECCTA score may not replace other CTA-based prediction scores for predicting CTO-PCI success.
