Abstract
BACKGROUND The utility of circulating tumor DNA to monitor molecular residual disease (MRD) has been clinically confirmed to predict disease recurrence in non-small cell lung cancer (NSCLC) patients after radical resection. Patients with longitudinal undetectable MRD show a favorable prognosis and might not benefit from adjuvant therapy. PATIENTS AND METHODS The CTONG 2201 trial is a prospective, multicenter, single-arm study (ClinicalTrials.gov identifier, NCT05457049), designed to evaluate the hypothesis that no adjuvant therapy is needed for patients with longitudinal undetectable MRD. Pathologically confirmed stage IB-IIIA NSCLC patients who have undergone radical resection will be screened. Only patients with 2 consecutive rounds of undetectable MRD will be enrolled (first at days 3-10, second at days 30 ± 7 after surgery), and admitted for imaging and MRD monitoring every 3 months without adjuvant therapy. The primary endpoint is the 2-year disease-free survival rate for those with longitudinal undetectable MRD. The recruitment phase began in August 2022 and 180 patients will be enrolled. CONCLUSIONS This prospective trial will contribute data to confirm the negative predictive value of MRD on adjuvant therapy for NSCLC patients. CLINICAL TRIAL REGISTRATION NCT05457049 (CTONG 2201).

Abstract
BACKGROUND Hypertensive intracerebral hemorrhage (HICH) is a life-threatening disease and lacks effective treatments. Previous studies have confirmed that metabolic profiles altered after ischemic stroke, but how brain metabolism changes after HICH was unclear. This study aimed to explore the metabolic profiles after HICH and the therapeutic effects of soyasaponin I on HICH. METHODS HICH model was established first. Hematoxylin and eosin staining was used to estimate the pathological changes after HICH. Western blot and Evans blue extravasation assay were applied to determine the integrity of the blood-brain barrier (BBB). Enzyme-linked immunosorbent assay was used to detect the activation of the renin-angiotensin-aldosterone system (RAAS). Next, liquid chromatography-mass spectrometry-untargeted metabolomics was utilized to analyze the metabolic profiles of brain tissues after HICH. Finally, soyasaponin I was administered to HICH rats, and the severity of HICH and activation of the RAAS were further assessed. RESULTS We successfully constructed HICH model. HICH significantly impaired BBB integrity and activated RAAS. HICH increased PE(14:0/24:1(15Z)), arachidonoyl serinol, PS(18:0/22:6(4Z, 7Z, 10Z, 13Z, 16Z, and 19Z)), PS(20:1(11Z)/20:5(5Z, 8Z, 11Z, 14Z, and 17Z)), glucose 1-phosphate, etc., in the brain, whereas decreased creatine, tripamide, D-N-(carboxyacetyl)alanine, N-acetylaspartate, N-acetylaspartylglutamic acid, and so on in the hemorrhagic hemisphere. Cerebral soyasaponin I was found to be downregulated after HICH and supplementation of soyasaponin I inactivated the RAAS and alleviated HICH. CONCLUSION The metabolic profiles of the brains changed after HICH. Soyasaponin I alleviated HICH via inhibiting the RAAS and may serve as an effective drug for the treatment of HICH in the future.

Abstract
BACKGROUND Ferroptosis has excellent potential in glioblastoma (GBM) therapy. In this study, we attempted to explore the effect of miR 491-5p on ferroptosis in GBM. METHODS In this study, publicly available ferroptosis-related genome maps were used to screen genes upregulated in GBM and their target genes. The Spearman correlation coefficient was applied to analyze the correlation between the tumor protein p53 gene (TP53) and miR-491-5p. The expressions of miR-491-5p and TP53 were determined. The protein abundances of the TP53-encoded factors p53 and p21 were measured. Cell proliferation, migration and invasion were assessed. We pretreated U251MG cells and GBM mice with a ferroptosis inducer (erastin). The mitochondrial state was observed. The contents of reactive oxygen species (ROS), total Fe and Fe2+ were calculated. RESULTS The level of TP53 was significantly increased in GBM and negatively correlated with miR-491-5p. miR-491-5p overexpression promoted U251MG cell proliferation, migration and invasion and interfered with the p53/p21 pathway. TP53 supplement reversed the effects of miR-491-5p. U251MG cells and GBM mice exhibited significant accumulations of ROS and iron. Erastin promoted the expression of TP53. Inhibition of TP53 reversed erastin-induced physiological phenotypes. Moreover, miR-491-5p overexpression caused a decrease in the number of damaged mitochondria and the contents of ROS, total Fe and Fe2+. TP53 supplement disrupted miR-491-5p-repressed ferroptosis. Erastin could inhibit GBM growth, and miR-491-5p overexpression impeded the therapeutic effect of erastin. CONCLUSIONS Our findings reveal the functional diversity of miR-491-5p in GBM and suggest that miR-491-5p/TP53 signaling hinders the sensitivity of GBM to ferroptosis through the p53/p21 pathway.

Abstract
Objective: To analyze the clinical features and prognosis of lung cancer patients with metastasis-induced acute pancreatitis (MIAP), and to provide clues for early diagnosis. Methods: The characteristics and prognosis of 8 patients with MIAP in lung cancer admitted to Peking Union Medical College Hospital from January 2002 to September 2019 were retrospectively analyzed and were compared with non-tumor-induced AP. Results: Sevencases(7/8) were Mild AP, one (1/8) was Severe AP. Four patients (4/8) presented with AP as the reporting sign and lung cancer was not diagnosed until (112±36) days after the onset of AP. Clinical manifestations included abdominal pain (8/8), weight loss (4/8), nausea and vomiting (2/8), and jaundice (1/8). Stages of lung cancer were all Ⅳ.Histopathology proved that seven cases (7/8) were small cell lung cancer, and one case (1/8) was poorly differentiated adenocarcinoma. The median survival time was 11 months. Compared with non-tumor-induced AP, lung cancer patients with MIAP were older[(62±9) vs (48±15), P=0.018], the incidence of primary pancreatic duct dilatation (37.5% vs 3.1%, P=0.004) and abdominal lymphadenopathy (37.5% vs 6.3%, P=0.017) were higher; the level of hemoglobin [105.3±15.6) g/L vs (147.9±24.8) g/L, P<0.001] and hematocrit [(31.4±5.3) vs (42.5±6.1), P<0.001] were lower. Conclusions: Patientswith MIAP in lung cancer had poor outcome and unspecific symptoms. Old age, anemia, main pancreatic duct dilatation and abdominal lymphadenopathy are diagnostic clues that merit clinical attention.

Abstract
Objective: To provide helpful continued medical education (CME) for physicians and improve gout treatment, we conducted a questionnaire survey to investigate physicians' knowledge in nine districts of Beijing. Methods: A questionnaire survey including ten gout-related questions was conducted among 298 physicians in Beijing. Demographic data and previous gout CME experience were collected. Chi-square test or Student's t test, univariate analysis and logistic regression analysis were used to evaluate the relevant factors of physicians' knowledge level. Results: A total of 250 valid copies were collected including 127 from community service centers (CSC), 123 from tertiary hospitals. The correct answer rate of gout etiology, pathogenesis and attack symptoms were over 70% in both groups. 45.5% (56/123) CSC doctors and 57.4% (66/115) tertiary doctors answered right drugs to control acute gout attack (P=0.067). Only 42.3% (52/123) in CSC and 53.4% (63/118) in hospitals chose allopurinol as a urate-lowering drug (ULT), while 46.3% (57/123) and 32.2% (38/118) doctors considered colchicine as a ULT drug (P=0.084) respectively. Near half doctors considered that gout patients should take long-term ULT [40.5% (51/126) vs. 57.6%(68/118)respectively, P=0.007]. Univariate analysis showed that CME training could improve gout-related knowledge in CRC doctors. Conclusion: Most CSC doctors generally understand basic knowledge of gout, while confusion of treatment is still significant. CME especially including standard gout treatment should be performed by doctors in tertiary hospitals.

Abstract
Objective: To summarize the experience of renal autotransplantation for severe iatrogenic proximal ureteral damage and renal artery aneurysms in eight patients and to explore the clinical application value of renal autotransplantation. Methods: Two patients of renal artery aneurysms and six patients of severe iatrogenic proximal ureteral damage between January 2010 and March 2018 in our center were retrospectively reviewed. Results: The procedures of eight cases were successful, with immediate return of renal function in the patients. The warm ischemia time was (3±1) minutes, the total operation time was (340±164) min, and the estimated blood loss was (180±60) ml, respectively. For renal artery anastomosis, six patients of severe iatrogenic proximal ureteral damage received end-to-end anastomosis between the internal iliac artery and renal artery, and two patients of renal artery aneurysms were treated with renal artery and internal iliac artery for reconstruction, then end-to-side anastomosis to recipien external iliac artery. A direct ureterovesical anastomosis was performed in seven patients, one patient was received pyeloureteroplasty. No serious complications of blood vessel and ureter were found during perioperative and long-term follow-up. All cases follow-up hitherto have normal renal function and blood pressure. Conclusions: Renal autotransplantation can be appropriate for patients with proximal ureteral loss and complex hilar renal artery aneurysms. In addition, it is able to protect renal functions to the most extent and provides a surgical alterative for complex renal diseases.

Abstract
Non-functioning pituitary adenomas (NFPAs) are the most frequent pituitary tumors. The elucidation of the mechanisms of aggressive NFPAs in bone destruction is required in order to guide the clinical diagnosis and treatment of NFPAs. In the present study, we investigated the differential proteomics of fibroblasts isolated from clinical specimens of NFPAs with or without bone destruction. Proteomic analysis revealed a group of molecules associated with cytoskeleton organization, including caldesmon, were differentially expressed between fibroblasts isolated from bone destruction NFPAs (BD-NFPAs) and fibroblasts isolated from non-bone destruction NFPAs (NBD-NFPAs). The secreted proteins analysis found that osteopontin was significantly upregulated in BD-NFPAs fibroblasts. Furthermore, immunohistochemical staining of the NFPAs clinical samples showed that the expression of caldesmon in stromal cells and the expression of osteopontin in both tumor cells and stroma were significantly increased in BD-NFPAs. Taken together, our results indicate a possible way that osteopontin secreted from both NFPA cells and surrounding fibroblasts modify caldesmon expression and polymerization in fibroblasts, which may contribute to bone destruction in NFPA patients.

Abstract
Objective: To fabricate Ti alloy frameworks for a maxillary complete denture with three-dimensional printing (3DP) technique, such as selective laser melting (SLM) and electron beam melting (EBM), and to evaluate the microstructure of these frameworks and their adaptation to the die stone models. Methods: Thirty pairs of edentulous casts were divided into 3 groups randomly and equally. In each group, one of the three techniques (SLM, EBM, conventional technique) was used to fabricate Ti alloy frameworks. The base-cast sets were transversally sectioned into 3 sections at the distal of canines, mesial of first molars, and the posterior palatal zone. The gap between the metal base and cast was measured in the 3 sections. Stereoscopic microscope was used to measure the gap. Three pieces of specimens of 5 mm diameter were fabricated with Ti alloy by SLM, EBM and the traditional casting technology (as mentioned above). Scanning electron microscope (SEM) was used to evaluate the differences of microstructure among these specimens. Results: The gaps between the metal base and cast were (99.4±17.0), (98.2±26.1), and (99.6± 16.1) μm in conventional method; (99.4 ± 22.8), (83.1 ± 19.3), and (103.3 ± 13.8) μm in SLM technique; (248.3±70.3), (279.1±71.9), and (189.1±31.6) μm in EBM technique. There was no statistical difference in the value of gaps between SLM Ti alloy and conventional method Ti alloy group (P>0.05). There was statistical difference among EBM Ti alloy, conventional method Ti alloy and SLM Ti alloy group (P<0.05). The SLM Ti alloy showed more uniform and compact microstructure than the cast Ti alloy and EBM Ti alloy did. Conclusions: SLM technique showed initial feasibility to manufacture the dental base of complete denture. The mechanical properties and microstructure of the denture frameworks prepared by SLM indicate that these dentures are appropriate for clinical use. EBM technique is inadequate to make a complete denture now.

Abstract
OBJECTIVE The aim of this study was to explore a panel of useful markers in differential diagnosis of primary endocervical adenocarcinoma (ECA) and endometrial adenocarcinoma (EMA). Materials anid Methods: Thirty-three ECAs and 31 EMAs were collected and examined for high-risk human papillomavirus (hr-HPV) (16/18) DNA using in situ hybridization, and for p16, vimentin, ER, PR expression using immunohistochemistry (IHC). RESULTS Detection rate of hr-HPV (16/18) DNA in ECA (72.7%, 24/33) was significantly higher than that in EMA (12.9%, 4/31) (p < 0.01). Twenty-four of 33 (72.7%) cases of ECA, but only five of 31 (16.1%) cases of EMA showed high expression of pl6. Twenty-three of 24 (95.8%) hr-HPV DNA-positive ECA and all four (100.0%) hr-HPV DNA-positive EMA showed high levels of pl6 expression. High expression rates of vimentin (90.3%, 28/31), ER (58.1%, 18/31), and PR (71.0%, 22/31) in EMA were significantly higher than those in ECA, respectively (p < 0.01). CONCLUSION Detection of hr-HPV DNA combined with immunohistochemical expressions of pl6, vimentin, ER, and PR have important value in differential diagnosis between ECA and EMA.

Abstract
The levels and health risks of arsenic and heavy metals (As, Ba, Cd, Co, Cr, Cu, Mn, Ni, Pb, and Zn) in the suspended particulate matter (SPM) collected from an urban household environment in Beijing of China for 12 months were investigated. The mean concentrations of the studied toxic elements were higher and lower than crustal abundance and PM2.5 in the urban outdoors of Beijing. The concentrations of the studied elements displayed significant seasonality. The highest concentrations of the total elements occurred in winter, followed by autumn, while the lowest concentrations were recorded in summer. Based on the calculated values of enrichment factor (EF) and geoaccumulation index (Igeo), the levels for As and Cu were heavily contaminated, while those for Cd, Pb, and Zn were extremely contaminated. As and Pb might pose risks to children and adults via ingestion exposure. The accumulative risks of multi-elements resulted from dermal contact and inhalation exposures were not negligible. More attention should be paid to reducing the non-carcinogenic and carcinogenic health risks posed by the toxic elements bound to urban household SPM particles via ingestion, inhalation, and dermal contact exposure.

Abstract
Different pig breeds have shown differential susceptibility to the pathogen infection; however, molecular mechanisms of the infection susceptibility are not fully understood. Streptococcus suis type 2 (SS2) is an important zoonotic pathogen. To identify the genes responsible for infection susceptibility, pigs from two different breeds (Enshi black and Landrace) were inoculated with SS2 and their spleen transcriptome profiles were investigated in the present study. The differentially expressed genes (DEGs) were analyzed from infected versus control pigs in each breed, and then compared between both pig breeds. Enshi black pig showed more DEGs than Landrace (830 vs. 611) and most of these were due to down-regulated genes (543 vs. 387). However some DEGs were uniquely expressed in one breed, some were expressed in opposite direction in both breeds. A number of candidate genes and pathways are identified which might be involved in susceptibility to SS2, for example, MMP9 and Resistin were only significantly expressed in Landrace. NPG3 and PMAP23 were up-regulated in Landrace whereas down-regulated in Enshi black. LENG8 in control Landrace have inherently higher expression than control Enshi black. IGKV6 is down-regulated in Landrace but up-regulated in Enshi black. Overall, the transcriptome profiles are consistent with the clinical signs, i.e. the Enshi black is more susceptible to SS2 infection than Landrace. This is the first study to identify differential gene expression between indigenous and modern commercial pigs after in vivo SS2 infection using RNA-seq. The significant DEGs in splenic profiles between two pig breeds suggested considerable involvement of genetic background in susceptibility to the SS2 infection in pigs.

Abstract
OBJECTIVE The aim of this study was to explore the potentiality of beta-catenin, Glut-1 and PTEN proteins as markers for a diagnosis of endometrial intraepithelial neoplasia (EIN). DESIGN Ten proliferative endometrium, 83 endometrial hyperplasia (59 benign hyperplasia, 24 EIN) and 24 endometrioid adenocarcinoma sections were immunostained for beta-catenin, Glut-1 and PTEN protein expression. RESULTS (1) Abnormal expression of beta-catenin was detected in 10% of benign hyperplasia, 50% of EIN and 67% of endometriold adenocarcinoma. (2) Overexpression of Glut-1 was present in 58% of EIN and 71% of endometrioid adenocarcinoma. (3) Complete loss of PTEN immunoreactivity was found in 20% of proliferative endometrium, 29% of benign hyperplasia, 38% of EIN and 63% of endometrioid adenocarcinoma. CONCLUSIONS The abnormal expression of beta-catenin and overexpression of Glut-1 may be useful markers in distinguishing benign hyperplasia from EIN, whereas lack of PTEN expression is not an appropriate marker for a diagnosis of EIN.

Abstract
The expression of placental hormones in 91 malignant trophoblastic neoplasms was studied immunohistochemically using a panel of antibodies against hCG, human placental lactogen (hPL) and pregnancy-specific 1-glycoprotein (SP). The results indicated that the expression of hCG in invasive moles was weaker than that in choriocarcinoma, but the expression of hPL and SP1 was stronger than those in choriocarcinoma. The expression of hPL and SP1 in the metastatic tumors of invasive moles was weaker than the expression at in the primary tumors, but the secretory capacity of hCG in metastatic choriocarcinomas was stronger than that in the primary neoplasms. In this study, the qualities of expression of the placental hormones in invasive moles and choriocarcinomas corresponded to the degree of tumor malignancy, the biological behaviour and the grading of trophoblastic cell differentiation. We believe that the detection of hCG, hPL and SP1, in malignant trophoblastic neoplasms was of value for establishing tumor diagnosis and typing and for judgement on prognosis.
