Expert consensus, as an important supplement to clinical practice guidelines, supports clinical decision-making when evidence is lacking or controversial. Compared to clinical practice guidelines, the presentation of expert consensus is more diverse. Currently, there are no reporting guidelines for expert consensus in clinical and public health decision-making. The RIGHT (Reporting Items for Practice Guidelines in Healthcare) checklist is the most commonly used international guideline reporting standard, and is often referred to when writing expert consensus. However, the RIGHT checklist does not include a section on consensus formation methods; while the ACCORD (ACcurate COnsensus Reporting Document) checklist includes reporting requirements for consensus formation methods, but not for reporting recommendations. Therefore, this article integrates the RIGHT and ACCORD reporting checklists and proposes an integrated reporting framework (TIMER-DO) to help authors combine these two commonly used international reporting standards and complete the standardized reporting of expert consensus.

[Objective] To summarize the clinical manifestations, pathological characteristics, treatment options and prognosis of the world's first case of prostate ductal adenocarcinoma (PDA) complicated with prostate mucinous adenocarcinoma (PMA). [Methods] The clinical and follow-up data of a patient with PDA and PMA treated in Zhongnan Hospital of Wuhan University were retrospectively analyzed, and relevant literature in PubMed and CNKI databases was retrieved. [Results] The patient sought medical attention due to dysuria, frequent urination, urinary urgency and urinary pain for more than half a year, and was admitted to hospital 3 times in total.The initial diagnosis upon the first admission was benign prostatic hyperplasia complicated with prostatic abscess.After 2 months, the patient was readmitted due to worsening symptoms, received transurethral bladder neck incision+ cystoscopy+ transurethral plasma resection of the prostate, and postoperative diagnosis confirmed PDA with local PMA.Three months after surgery, the patient had bleeding.After auxiliary examinations revealed extensive metastasis, he received hormonal therapy.After 9 months, the patient died due to multiple lung metastases. [Conclusion] Early diagnosis has a significant impact on the treatment and prognosis, but there have been no previous reports of PDA combined with PMA, so the lack of specific biomarkers in the early stage has led to missed diagnosis or misdiagnoses.There is no specific treatment for PDA with PMA. Radical prostatectomy was not satisfactory in the treatment of this case.

OBJECTIVES: To investigate the effect and mechanism of lipid nanoparticle (LNP) delivery of small interfering RNA (siRNA) targeting Cyp2e1 gene on subacute alcoholic liver injury in mice. METHODS: siRNA targeting Cyp2e1 gene was encapsulated in LNP (si-Cyp2e1 LNP) by microfluidic technique and the resulting LNPs were characterized. The optimal dose of si-Cyp2e1 LNP administration was screened. Forty female C57BL/6N mice were randomly divided into blank control group, model control group, si-Cyp2e1 LNP group, LNP control group and metadoxine group. The subacute alcoholic liver injury mouse model was induced by ethanol feeding for 10 d plus ethanol gavage for the last 3 d. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities, and the superoxide dismutase (SOD) activity as well as malondialdehyde, reactive oxygen species, glutathione, triacylglycerol, total cholesterol contents in liver tissue were measured in each group, and liver index was calculated. The expression of genes related to oxidative stress, lipid synthesis and inflammation in each group of mice were measured by realtime RT-PCR. RESULTS: Compared with the model control group, the levels of liver index, serum ALT, AST activities, malondialdehyde, reactive oxygen species, triacylglycerol, total cholesterol contents in liver tissue decreased, but the SOD activity as well as glutathione increased in the si-Cyp2e1 LNP group (all P<0.01). Hematoxylin-eosin staining result showed disorganized hepatocytes with sparse cytoplasm and a large number of fat vacuoles and necrosis in the model control group, while the si-Cyp2e1 LNP group had uniformly sized and arranged hepatocytes with normal liver tissue morphology and structure. Oil red O staining result showed si-Cyp2e1 LNP group had lower fat content of the liver compared to the model control group (P<0.01), and no fat droplets accumulated. Anti-F4/80 monoclonal antibody fluorescence immunohistochemistry showed that the si-Cyp2e1 LNP group had lower cumulative optical density values compared to the model control group (P<0.01) and no significant inflammatory reaction. Compared with the model control group, the expression of catalytic genes P47phox, P67phox and Gp91phox were reduced (all P<0.01), while the expression of the antioxidant enzyme genes Sod1, Gsh-rd and Gsh-px were increased (all P<0.01). The mRNA expression of the lipid metabolism genes Pgc-1α and Cpt1 were increased (all P<0.01) and the lipid synthesis-related genes Srebp1c, Acc and Fasn were decreased (all P<0.01); the expression of liver inflammation-related genes Tgf-β, Tnf-α and Il-6 were decreased (all P<0.01). CONCLUSIONS The si-Cyp2e1 LNP may attenuate subacute alcoholic liver injury in mice mainly by reducing reactive oxygen levels, increasing antioxidant activity, blocking oxidative stress pathways and reducing ethanol-induced steatosis and inflammation.

Alcoholic liver disease (ALD) results from continuous and heavy alcohol consumption. The current treatment strategy for ALD is based on alcohol withdrawal coupled with antioxidant drug intervention, which is a long process with poor efficacy and low patient compliance. Alcohol-induced CYP2E1 upregulation has been demonstrated as a key regulator of ALD, but CYP2E1 knockdown in humans was impractical, and pharmacological inhibition of CYP2E1 by a clinically relevant approach for treating ALD was not shown. In this study, we developed a RNAi therapeutics delivered by lipid nanoparticle, and treated mice fed on Lieber-DeCarli ethanol liquid diet weekly for up to 12 weeks. This RNAi-based inhibition of Cyp2e1 expression reduced reactive oxygen species and oxidative stress in mouse livers, and contributed to improved ALD symptoms in mice. The liver fat accumulation, hepatocyte inflammation, and fibrosis were reduced in ALD models. Therefore, this study suggested the feasibility of RNAi targeting to CYP2E1 as a potential therapeutic tool to the development of ALD.

The establishment of effective animal models is crucial for disease research.Dietary induction is a common method to establish animal models of non-alcoholic fatty liver disease(NAFLD).The common animal models of diet-induced NAFLD mainly include high fat and sugar,high fat and cholesterol,and choline-deficient diet-induced models.Because of the various nutrients ingested in different modeling method,pathological characteristics of the liver,such as fatty deformation,inflammation,and fibrosis,are different.Additionally,animal models vary in terms of disease progression,disease severity,and applicable studies.This study analyzed and compared the common animal models of NAFLD induced by various diets in terms of modeling method,modeling time,pathological characteristics,applicable research,and related advantages and disadvantages to provide a reference for NAFLD researchers to select animal models.

Objective: To evaluate the feasibility of identification and preservation of arm lymphatics (DEPART) in axillary lymph node dissection (ALND) for breast cancer to prevent arm lymphedema. Methods: A randomized controlled study method was used. Two hundred and sixty-five patients who underwent breast cancer surgery at the Department of Thyroid and Breast Surgery, Zhongnan Hospital of Wuhan University from November 2017 to June 2018 were included, and the patients were randomly divided into ALND+ DEPART group (132 patients) and standard ALND group (133 patients) by random number table method. In the ALND+ DEPART group, indocyanine green and methylene blue were injected as tracers before surgery, and the arm sentinel nodes was visualized by staged tracing during intraoperative dissection of axillary lymph nodes. Partial frozen sections were made of arm lymph nodes >1 cm in length and hard and suspicious of metastasis, and arm lymph nodes and lymphatic vessels were selectively preserved. Patients in the standard ALND group underwent standard ALND. Objective and subjective indexes of arm lymphedema were evaluated by 5-point circumference measurement and Norman questionnaire. Results: Among 132 breast cancer patients in the ALND+ DEPART group, 121 (91.7%) completed DEPART. There were no statistically significant differences in age, body mass index, pathological type, dissection number of axillary lymph node, N stage, TNM stage, molecular typing, and regional radiotherapy between the ALND+ DEPART and standard ALND groups (P>0.05). At a median follow-up of 24 months, assessment by the 5-point circumference measurement showed that the incidence rates of lymphedema in the ALND+ DEPART and standard ALND groups were 5.0% (6/121) and 15.8% (21/133), respectively, with statistically significant differences (P=0.005). Assessment by the Norman questionnaire showed that the incidence rates of lymphedema in the ALND+ DEPART and standard ALND groups were 5.8% (7/121) and 21.8% (29/133), respectively, with a statistically significant difference (P<0.001). No local regional recurrence was observed in either group during the follow-up period. Conclusion: For breast cancer patients with positive axillary lymph nodes, the administration of DEPART during ALND can reduce or avoid the occurrence of arm lymphedema without compromising oncology safety.

Objective: To explore the values of intraoperative fine-needle aspiration (IFNA) and parathyroid hormone (PTH) detection in the eluate of aspirated tissue during parathyroidectomy. Methods: Fifty-four patients with secondary hyperparathyroidism (SHPT) including 24 males and 30 females, aged 20-83 years, admitted to Zhongnan Hospital of Wuhan University from January 2019 to October 2019, were included. All patients received subtotal parathyroidectomy with autologous transplantation, during surgery, IFNA and PTH detection in the eluate of aspirated tissue were performed, and also routine postoperative pathological examination was performed. The results of PTH detection in the eluate of aspirated tissue and postoperative pathological examinations were compared and analyzed by SPSS and R software for evaluating of the sensitivity, specificity, positive predictive value, negative predictive value, misdiagnosis rate, missed diagnosis and accuracy. Results: Surgery was completed successfully in all patients. After surgery, the symptoms were improved in the patients except two who were asymptomatic. None had any serious postoperative complications such as hypocalcaemia or hoarseness. A total of 231 aspirated tissue samples were tested, of which 216 were identified as parathyroid and 15 non-parathyroid based on intraoperative PTH detection in tissue eluate; while 217 were confirmed as parathyroid tissues and 14 non-parathyroid tissues with postoperative pathological examinations. The specificity and sensitivity of intraoperative IFNA and PTH detection in tissue eluate for identifying parathyroid tissues were 99.5% and 100.0%, respectively. Conclusion: The IFNA and PTH detection in tissue eluate is a rapid, simple, and accurate procedure, which helps the surgeon to identify parathyroid tissue and to ensure the endocrine activity of preserved or autografted parathyroid tissue during parathyroidectomy.

Objective: To investigate the application efficacy of the "classification of external branch of superior laryngeal nerve (EBSLN)" combined with intraoperative neuromonitoring (IONM) in the dissection of EBSLN for protecting the nerve from injuery, compared with ligation of branches of the superior thyroid vessels without attempts to visually identify the nerve. Methods: A prospective randomized controled study was performed in our center. Patients subjected to thyroidectomy from January 2017 to June 2019 were randomly divided into 2 groups, patients in experimental group underwent thyroidectomy and "classification of EBSLN" with IONM to dissect EBSLN, and patients in control group received synchronous surgery without attempts to visually identify the nerve. The anatomical subtypes of EBSLN in experimental group were recorded. The voice handicap index 10 (VHI-10) score was evaluated and the movement of bilateral vocal cords was examined by laryngoscope before surgery, 1 month, 3 months, and 6 months after surgery, respectively. SPSS 26.0 statistical software was used for statistical analysis. Results: Among the 1 377 EBSLN from 827 patients (317 males and 510 females, aged 24-58 years old), 691 EBSLNs in experimental group and 686 EBSLNs in control group. Totally 98.3% of EBSLNs in experimental group were identified by IONM including 16.4% (113/691) for type Ⅰ, 21.3% (147/691) for type Ⅱa, 31.4% (217/691) for type Ⅱb, 10.4% (72/691) for type Ⅲa, 3.9% (27/691) for type Ⅲb, 16.6% (115/691) for type Ⅲc. There was no statistical significance difference in baseline data between 2 groups (all P>0.05). All patients were followed up for more than 6 months. The postoperative nerve injury rate of experimental group was significantly lower than that of control group (1.2% vs. 7.5%, χ²=12.659, P<0.001), and the VHI-10 scores and laryngoscope results of experimental group were better than those of control group in three follow-up visits (P<0.001). With postoperative laryngoscope examination, 3 patients in the experimental group and 23 patients in the control group showed vocal cord relaxation, bilateral oblique asymmetry and other phenomena, which were considered as the results of permanent injury. Other patients with symptoms were relieved to varying degrees during the follow-up, and their symptoms were considered as the results of temporary injury. Conclusion: IONM combined with "classification of EBSLN" can reduce significantly the risk of EBSLN injury in thyroidectomy, which is better than direct ligation of branches without attempts to visually identify the nerve.
