In November 2024， the Expert Group on Alcohol-related Liver Disease released a position statement on metabolic dysfunction and alcohol-related liver disease （MetALD）. MetALD is a new subtype of steatotic liver disease and refers to MASLD patients with a relatively large amount of alcohol consumption. The position statement points out the importance of accurate evaluation of alcohol consumption and recommends to quantify alcohol consumption using standard methods and alcohol biomarkers， and a comprehensive diagnosis should be made based on metabolic risk factors. In addition， the position statement analyzes the influence of drinking pattern on the diagnosis of MetALD and recommends to consider long-term drinking history during typing. The position statement also discusses the complex association between drinking and the diseases including metabolic syndrome， hepatic steatosis， fibrosis， and type 2 diabetes mellitus， and it is pointed out that the hierarchical management of patients should be optimized based on liver histological models and noninvasive models. The position statement elaborates on the definition of MetALD， drinking assessment， the interaction between alcohol use and metabolic dysfunction， and the methods for comprehensive management of MetALD， in order to facilitate learning and provide guidance for clinicians and researchers in clinical practice.

Objective To explore the clinical application value of non-inflatable mediastinoscopy combined with laparoscopic radical resection for esophageal cancer patients complicated with cardiovascular and pulmonary diseases.Methods A retrospective analysis was made on clinical data of 20 patients with esophageal cancer complicated with cardiovascular and pulmonary diseases treated with non-inflatable mediastinoscopy combined with laparoscopic radical resection in our hospital from January 2021 to October 2024.The cervical and abdominal surgical teams worked simultaneously.During the operation,a left neck incision was made to free the cervical esophagus.After inserting a mediastinoscope,an ultrasonic knife was used to free the thoracic esophagus from top to bottom and clean the lymph nodes adjacent to the esophagus.The laparoscopic procedure(freeing the stomach and esophagus from bottom to top)was connected in the mediastinum to complete the esophageal freedom,and a tubular stomach was made and anastomosed at the neck.Results All the 20 operations were successfully completed without conversion to thoracotomy.The operation time was(130.5±25.5)min,the intraoperative blood loss was(60.5±32.5)ml,a total of 3-11 mediastinal lymph nodes and1-5 abdominal lymph nodeswerecleared,andthe postoperative hospital stay was(20.0±6.0)d.There were 2 cases of anastomotic leakage,2 cases of anastomotic stenosis,2 cases of pleural effusion,2 cases of pulmonary infection,1 case of chylothorax,and 1 case of recurrent laryngeal nerve injury.After conservative treatment,all of which were cured.Postoperative pathology showed 18 cases of squamous cell carcinoma and 2 cases of adenocarcinoma.Postoperative TNM staging was 6 cases in stage Ⅰ,10 cases in stage Ⅱ,and 4 cases in stage Ⅲ,consistent with preoperative evaluation.All the20 cases were followed up for1-24 months,with a median follow-up time of 12 months.CT re-examinations showed no recurrence,and no death case was recorded.Conclusion Non-inflatable mediastinoscopy combined with laparoscopic radical resection is safe and feasible for esophageal cancer patients complicated with cardiovascular and pulmonary diseases.

ObjectiveTo understand the prevalence of hookworm infection and its relevant behavioral factors in rural areas of Tiantai County， Zhejiang Province， and to provide scientific evidence for prevention and control of hookworm disease. MethodsBy using a stratified cluster random sampling strategy， local residents aged ≥3 years was divided into 5 districts according to geographical location； furthermore， those in one administrative village （surveillance site） were investigated in each district. Species of hookworm were identified by filter paper culture in vitro， and enterobius vermicularis eggs were detected by cellophane anal swab in children aged 3‒9 year. Risk factors were determined by questionnaire. ResultsA total of 1 013 residents were investigated in 5 surveillance sites. Thirty nine cases with hookworm infection were detected， with the total infection rate of 3.85% . All species detected were determined to be Necator americanus. The infection rate significantly differed across the towns （χ²=48.32， P<0.05）， with the highest rate in Nanping Town （10.95%） . It significantly differed by age groups （χ²=65.65， P<0.05）， with the highest rate in those aged >70 years （9.75%）. Furthermore， it decreased with educational background. It was significantly associated with fertilize with fresh manure （χ²=6.87， P<0.05） and barefoot labor （χ²=157.69， P<0.05）. ConclusionThe overall infection rate of hookworm in Tiantai County remains low. Dominant species of hookworm is hookworm Necator americanus. It is necessary to strengthen the advocacy of hookworm prevention and control knowledge， improve hygiene in work and life style， and increase self-protection awareness.

Objective:To further improve the understanding of paroxysmal nocturnal hemoglobinuria (PNH), we retrospectively analyzed and summarized the clinical characteristics, treatment status, and survival status of patients with PNH in Zhejiang Province.Methods:This study included 289 patients with PNH who visited 20 hospitals in Zhejiang Province. Their clinical characteristics, comorbidity, laboratory test results, and medications were analyzed and summarized.Results:Among the 289 patients with PNH, 148 males and 141 females, with a median onset age of 45 (16-87) years and a peak onset age of 20-49 years (57.8% ). The median lactic dehydrogenase (LDH) level was 1 142 (604-1 925) U/L. Classified by type, 70.9% (166/234) were classical, 24.4% (57/234) were PNH/bone marrow failure (BMF), and 4.7% (11/234) were subclinical. The main clinical manifestations included fatigue or weakness (80.8%, 235/289), dizziness (73.4%, 212/289), darkened urine color (66.2%, 179/272), and jaundice (46.2%, 126/270). Common comorbidities were hemoglobinuria (58.7% ), renal dysfunction (17.6% ), and thrombosis (15.0% ). Moreover, 82.3% of the patients received glucocorticoid therapy, 70.9% required blood transfusion, 30.7% used immunosuppressive agents, 13.8% received anticoagulant therapy, and 6.3% received allogeneic hematopoietic stem cell transplantation. The 10-year overall survival (OS) rate was 84.4% (95% CI 78.0% -91.3% ) . Conclusion:Patients with PNH are more common in young and middle-aged people, with a similar incidence rate between men and women. Common clinical manifestations include fatigue, hemoglobinuria, jaundice, renal dysfunction, and recurrent thrombosis. The 10-year OS of this group is similar to reports from other centers in China.

Objective To observe the value of shear wave elastography(SWE),superb microvascular imaging(SMI)and their combination with conventional ultrasound for diagnosing cervical cancer.Methods Data of 178 patients with cervical lesion confirmed by pathology were retrospectively analyzed.The patients were divided into malignant group(n=32)and benign group(n=146),and those in benign group were further divided into low-grade or high-grade cervical intraepithelial neoplasia subgroups,cervical leiomyosarcoma subgroup,cervical polyps subgroup and cervicitis subgroup.The manifestations of lesion on conventional ultrasound,SWE and SMI were observed,and the mean value of Young's modulus(Emean)and SMI flow index(Ratio)were collected.The optimal cut-off value of SWE Emean and SMI Ratio were obtained with receiver operating characteristic(ROC)curves,and the classification of benign or malignant lesions were predicted.The consistency of predictive results and pathology results were assessed with the Kappa test.The diagnostic efficacies of conventional ultrasound,SWE and SMI alone and their combination were compared.Results The age of patients in malignant group was higher than that in benign group(P＜0.05).SWE Emean and SMI Ratio were both higher in malignant group than those in each benign subgroup(all P＜0.05).Taken 44.35 kPa and 3.95％ as the best cut-off values,the consistency of SWE Emean classification results and pathological results was good(Kappa=0.818),while of SMI Ratio was moderate(Kappa=0.453).The efficacy of conventional ultrasound,SWE and SMI alone for classifying benign and malignant cervical lesions(AUC=0.845,0.914,0.892)were all higher than that of their combination(AUC=0.806,all adjusted P＜0.05).The sensitivity of SWE and SMI for diagnosing cervical cancer was 90.60％ and 93.78％ respectively,with specificity of 95.20％ and 72.60％,respectively.Conclusion SWE hag higher efficacy for diagnosing cervical cancer,while SMI had better sensitivity but lower specificity.Combination of conventional ultrasound,SWE and SWI did not increase the efficacy of ultrasound for diagnosing cervical cancer.

ObjectiveIn recent years， with the sharp decline of wild resources in Arisaematis Rhizoma and Pinelliae Rhizoma and the immaturity of medicinal cultivation technology， their adulterants have appeared frequently in the market， and the main identifying characteristics have mostly disappeared in the circulation of medicinal materials. Therefore， there is an urgent need to establish a molecular identification method that can quickly and effectively identify the specificity of Arisaematis Rhizoma and Pinelliae Rhizoma. MethodAfter comparison of the rbcL sequences of Arisaematis Rhizoma，Pinelliae Rhizoma， and their adulterants， the specific enzyme cleavage sites Hae Ⅲ and Dra Ⅰ of Arisaematis Rhizoma and Pinelliae Rhizoma， respectively， were selected and identified by polymerase chain reaction-restriction fragment length polymorphism（PCR-RFLP）. The main system conditions of PCR-RFLP reaction were established and optimized， and their durability and the ability to detect genuine， adulterants， and mixed counterfeits were investigated. ResultThe PCR-RFLP identification method of Arisaematis Rhizoma and Pinelliae Rhizoma was established. After specific primer amplification， Arisaematis Rhizoma and Pinelliae Rhizoma could be digested by Hae Ⅲ and Dra Ⅰ-restricted endonucleases respectively， at annealing temperature of 54 ℃， the number of cycles of 35， and the amount of DNA template of 3-30 ng， producing two fragments or small cut fragments with a single band between 100-250 bp， whereas the mixed counterfeits were not cleaved and both showed a band at 250 bp. The method is highly accurate in identifying adulterants and mixed counterfeits of Arisaematis Rhizoma or Pinelliae Rhizoma. ConclusionThe PCR-RFLP method developed in this study allows for the rapid identification of Arisaematis Rhizoma and Pinelliae Rhizoma.

The International Agency for Research on Cancer (IARC) defines shift work as any arrangement of daily working hours other than the standard daylight hours (typically 7:00/8:00 am–5:00/6:00 pm). To meet the needs of rapid socioeconomic development, shift work is becoming more and more common. The impact of shift work, especially night shift work, on human health cannot be ignored. Female's health is not only important to the well-being of themselves, but also has a far-reaching impact on their children and even their entire family. Increasing epidemiological studies have focused on the effects of night shift work on female's reproductive health. This article reviewed epidemiological evidence of the associations between night shift work and reproductive outcomes, e.g. menstrual cycle, endometriosis, pregnancy rate, adverse pregnancy outcomes, and ovarian cancer. The potential biological mechanisms connecting night shift work to female reproductive health were also introduced, e.g. melatonin regulation, clock gene regulation, and sex hormone regulation. Through this review, we propose to provide a reference for determining occupational risk factors, conducting subsequent relevant studies, and formulating rational health promotion strategies.
