After continuous development and improvement, lung transplantation has become the preferred means to treat a variety of benign end-stage lung diseases. However, the field of lung transplantation still faces many challenges, including shortage of donor resources, preservation and maintenance of donor lungs, and postoperative complications. Lung tissue samples removed after lung transplantation are excellent clinical resources for the study of benign end-stage lung disease and perioperative complications of lung transplantation. However, at present, the collection, storage and utilization of tissue samples after lung transplantation are limited to a single study, and unified technical specifications have not been formed. Based on the construction plan of the biobank for lung transplantation in the First Affiliated Hospital of Xi'an Jiaotong University, this study reviewed the practical experience in the collection, storage and utilization of lung transplant tissue samples in the aspects of ethical review, staffing, collection process, storage method, quality control and efficient utilization, in order to provide references for lung transplant related research.

Objective:To analyze the differences in clinical and endoscopic ultrasonography (EUS) findings between diffuse and focal IgG4-related autoimmune pancreatitis (IgG4-AIP).Methods:Data of patients diagnosed as having IgG4-AIP who underwent EUS at Chinese PLA General Hospital from September 2011 to April 2022 were retrospectively collected. General clinical data, EUS features, and postoperative pathology were analyzed for characteristic differences.Results:A total of 40 patients were included in the study, 60.03±10.87 years old, a higher proportion of males (85.0%, 34/40). All patients underwent EUS, and 28 underwent EUS-guided fine-needle aspiration. Among the 40 patients, 29 (72.5%) had diffuse type and 11 (27.5%) had focal type. Abdominal pain [65.5% (19/29) VS 18.2% (2/11), χ2=5.393, P=0.020] and thickening of the bile duct wall [51.7% (15/29) VS 9.1% (1/11), χ2=4.394, P=0.036] were more common in the diffuse type, while main pancreatic duct dilation [45.5% (5/11) VS 10.3% (3/29), χ2=4.146, P=0.042] was more common in the focal type, with the lesion most commonly located in the pancreatic head (90.9%, 10/11). There was no significant difference in the presence of chronic pancreatitis parenchymal changes between the two groups [34.5% (10/29) VS 27.3% (3/11), χ2=0.003, P=0.955]. Conclusion:There are certain differences in abdominal pain and biliary and pancreatic duct lesions between diffuse and focal AIP. The high expression of chronic pancreatitis characteristics is not observed in either group, which provides clues for the classification of AIP in clinical practice.

Metastasis accounts for 90% of breast cancer deaths, where the lethality could be attributed to the poor drug accumulation at the metastatic loci. The tolerance to chemotherapy induced by breast cancer stem cells (BCSCs) and their particular redox microenvironment further aggravate the therapeutic dilemma. To be specific, therapy-resistant BCSCs can differentiate into heterogeneous tumor cells constantly, and simultaneously dynamic maintenance of redox homeostasis promote tumor cells to retro-differentiate into stem-like state in response to cytotoxic chemotherapy. Herein, we develop a specifically-designed biomimic platform employing neutrophil membrane as shell to inherit a neutrophil-like tumor-targeting capability, and anchored chemotherapeutic and BCSCs-differentiating reagents with nitroimidazole (NI) to yield two hypoxia-responsive prodrugs, which could be encapsulated into a polymeric nitroimidazole core. The platform can actively target the lung metastasis sites of triple negative breast cancer (TNBC), and release the escorted drugs upon being triggered by the hypoxia microenvironment. During the responsiveness, the differentiating agent could promote transferring BCSCs into non-BCSCs, and simultaneously the nitroimidazole moieties conjugated on the polymer and prodrugs could modulate the tumor microenvironment by depleting nicotinamide adenine dinucleotide phosphate hydrogen (NADPH) and amplifying intracellular oxidative stress to prevent tumor cells retro-differentiation into BCSCs. In combination, the BCSCs differentiation and tumor microenvironment modulation synergistically could enhance the chemotherapeutic cytotoxicity, and remarkably suppress tumor growth and lung metastasis. Hopefully, this work can provide a new insight in to comprehensively treat TNBC and lung metastasis using a versatile platform.

Objective:To summarize the clinical experience of using V-shaped incision to excise scalp subcutaneous tumors.Methods:A retrospective analysis of the clinical data of patients with subcutaneous benign tumors admitted to the Department of Burns and Plastic Surgery of the Northern Theater General Hospital from August 2020 to December 2021 was conducted. The tumors were all above 3 cm in diameter and closely adhered to surrounding tissues, and all were removed using a V-shaped incision. During the operation, the scalp was incised along the design line, the V-shaped skin flap was lifted to affiliate the tumor removed. The incision was closed directly from the tip of "V" until the moderate tension attained. The scalp flap was spread smoothly on the wound surface, and the excess scalp tissue was removed to form a Y-shaped suture. The flap survival, complications, incision scar, hair growth around the incision and tumor recurrence were observed and followed up after operation.Results:A total of 20 cases were included, including 12 males and 8 females, with an average medical history of (3.6±1.9) years and a tumor diameter of (4.1±1.1) cm. There were 8 sebaceous cysts, 5 lipomas, and 7 epidermoid cysts. After operation, 18 flaps survived well, and 2 cases had epidermal necrosis at the tip of the flap, which healed after dressing change. During the follow-up period of 6-12 months, 3 patients experienced local scalp numbness, which improved within 3-6 months. In 20 cases, the scalp was flat, the incision scar was not hyperplastic, the scar was short visually, the surrounding hair grew normally, and no tumor recurrence happened.Conclusion:V-shaped incision is relatively easy to expose the tumor and can accurately remove excess skin. After operation, the scalp has a good flat appearance, so it is an ideal choice for large scalp subcutaneous tumors with close adhesion to the surrounding tissue.

Objective:To investigate the value of multi-slice spiral CT (MSCT) combined with three myocardial markers in the diagnosis of acute chest pain etiology.Methods:A retrospective study was conducted on 120 patients with acute chest pain admitted to the Affiliated Hospital of Jining Medical University from January 2020 to December 2020. All patients underwent MSCT imaging examination upon admission, and serum creatine kinase isoenzyme MB (CK-MB), troponin I (cTnI), and myoglobin (MYO) levels were also tested. The final clinical diagnosis was used as the judgment standard to draw a 2×2 four-square table, and calculate the value of MSCT, CK-MB, cTnI, and MYO in the diagnosis of acute chest pain etiology.Resultsl:Among the 120 acute chest pain patients included, 75 were diagnosed with acute coronary syndrome (62.50%), 16 with aortic dissection (13.33%), and 29 with pulmonary embolism (24.17%). The coincidence rate of MSCT diagnosis of coronary heart disease was 86.67%(65/75), the diagnosis of aortic dissection coincidence rate was 12/16, and the diagnosis of pulmonary embolism coincidence rate was 75.86%(22/29). The serum CK-MB, cTnI, and MYO levels in the coronary heart disease group were significantly higher than those in the aortic dissection group and pulmonary embolism group, and the differences were statistically significant (all P<0.05). There was no significant difference in serum CK-MB, cTnI, and MYO levels between the aortic dissection group and pulmonary embolism group (all P>0.05). The sensitivity of CK-MB, cTnI, and MYO in the differential diagnosis of acute chest pain patients with coronary heart disease and non-coronary heart disease were 93.33%, 85.33%, and 89.33%, respectively, and the specificity were 73.33%, 80.00%, and 77.78%, respectively. The areas under the receiver operating characteristic (ROC) curve were 0.833, 0.826, and 0.836, respectively. Conclusions:MSCT can better identify coronary heart disease, aortic dissection, and pulmonary embolism in patients with acute chest pain, while the three myocardial markers can better distinguish patients with coronary heart disease and non-coronary heart disease. Therefore, MSCT combined with myocardial markers should be used for the diagnosis of acute chest pain patients in clinical practice to facilitate early clinical diagnosis.

Objective To provide new ideas for promoting wound healing by digging and sorting out the medication rules in ancient classics and modern literatures. Methods The prescriptions for promoting wound healing recorded in literatures were collected to establish the database. The data mining technology was used for the analysis. Results 75 prescriptions and 203 traditional Chinese medicines were recorded in the ancient TCM literatures for promoting wound healing. The core medicines included frankincense, liquorice, angelica sinensis, angelica dahuricae, cortex phellodendri, myrrh, etc. They mainly belong to the class of clearing-heat drugs, promoting-circulation drugs, reinforcing drugs, relieving drugs, detoxification and tissue granulation drugs. Cluster analysis and association rule analysis were conducted for 16 core drugs. 4 cluster combinations ,15 groups of drug pairs and drug group association rules were obtained. Conclusion The prescription rules for wound healing mainly included clearing heat, promoting circulation, reinforcing, relieving, detoxification, and promoting tissue granulation. TCM wound treatment should be based on syndrome differentiation for fever, blood stasis, deficiency, anabrosis, exterior syndrome and poisoning.

Objective:To analyze the clinical characteristics of patients with acute glyphosate herbicide poisoning and the differences in the severity of poisoning.Methods:A retrospective analysis was performed on patients with acute glyphosate herbicide poisoning admitted to the First Affiliated Hospital of Zhengzhou University from January 2014 to December 2020. The general information, exposure time, poisoning dose, poisoning cause, poisoning route, clinical manifestations, laboratory examination results during hospitalization, treatment measures, hospital stays and prognosis of the patients were collected. The patients were graded according to the poisoning severity scoring standard of Chinese Expert Consensus on Diagnosis and Treatment of Acute Poisoning in 2016. The highest severity score during hospitalization was used as the final grade. According to the final grade, asymptomatic and mild patients were included in the mild group, and moderate, severe and death patients were included in the severe group. The independent sample T test or Mann-Whitney U test was used for measurement data, and χ2 test or Fisher's exact test was used for counting data. The differences of general data and clinical data between the two groups were compared. Results:According to the inclusion and exclusion criteria, 83 patients with acute glyphosate herbicide poisoning were selected as the study subjects. All patients survived, mainly mild poisoning (56.6%), with a male to female ratio of 33∶50, and an average age of 39 years. The number of poisoning cases increased yearly (the highest in 2019), and most cases occurred in spring and summer. The main cause of poisoning was suicide (71.1%), direct oral administration (83.1%) was the primary route of poisoning, and the dominating clinical manifestations were digestive symptoms (71.1%). Laboratory tests showed increased white blood cell count (WBC), neutrophil percentage (NEUT %) and D-dimer, and decreased hemoglobin and potassium. Compared with the mild group, patients in the severe group were older [(51±17) years vs. (35±19) years], had a higher proportion of suicide and direct oral administration, a longer hospital stay [8.0 (4.8, 12.0) d vs. 3.0 (2.0, 5.5) d], a higher dose of poisoning [200.0 (50.0, 200.0) mL vs. 30.0 (11.3, 57.5) mL], and higher NEUT % within 24 h of admission [(83.4±10.4) vs. (73.2±12.8)]. The increase of WBC, NEUT %, aspartate aminotransferase, prothrombin time, D-dimer and the decrease of serum potassium were more common in the severe group than the mild group, with statistical significance (all P<0.05). Conclusions:The number of patients with acute glyphosate herbicide poisoning is increasing yearly. Generally, the condition is mild and the prognosis is satisfying. The severity is more serious in the middle-aged and elderly patients andthose with direct oral administration, high toxic dose, and high NEUT % within 24 h of admission. Severe poisoning is more likely to cause changes in laboratory indicators.
