Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective:To analyze the relationship between inflammatory burden index (IBI) and the diagnosis and prognosis of gastric cancer.Methods:A total of 180 patients with gastric cancer admitted to the First Affiliated Hospital of Xi'an Medical University from January 1, 2017 to December 31, 2021 were selected as the gastric cancer group, 180 cases of gastric precancerous diseases treated in this hospital during the same period were selected as the precancerous disease group, 180 healthy individuals who underwent physical examinations in this hospital during the same period were selected as the control group. The value of IBI in the diagnosis of gastric cancer was analyzed. The IBI values of the three groups were compared by one-way analysis of variance, and the optimal cut-off values of different indicators were determined by receiver operator characteristic (ROC) curve to further evaluate the diagnostic value of IBI for gastric cancer. LASSO regression analysis was performed using the R software package glmnet to screen variables. Univariate and multivariate Cox regression analysis were performed on the screened variables to further determine the independent risk factors affecting the prognosis of patients with gastric cancer.Results:The levels of IBI in gastric cancer, precancerous disease, and control group were 46.69±8.38, 35.53±6.11, and 21.47±4.36, respectively, with a statistically significant difference ( F=681.45, P<0.001). Further pairwise comparisons showed that the gastric cancer group was higher than the precancerous disease group and the control group, and the precancerous disease group was higher than the control group, with statistically significant differences ( t=14.43, P<0.001; t=34.15, P<0.001; t=25.13, P<0.001). ROC curve analysis showed that the optimal cut-off value for the neutrophil to lymphocyte ratio (NLR) was 3.15 (AUC=0.65, 95% CI: 0.54-0.73), with a specificity of 92.31% and a sensitivity of 43.97%. The optimal cut-off value for the platelet to lymphocyte ratio (PLR) was 137.36 (AUC=0.59, 95% CI: 0.51-0.68), with a specificity of 93.66% and a sensitivity of 34.98%. The optimal cut-off value for lymphocyte to monocyte ratio (LMR) was 5.18 (AUC=0.69, 95% CI: 0.58-0.76), with a specificity of 61.29% and a sensitivity of 73.33%. The optimal cut-off value for panimmune inflammation value (PIV) was 276.57 (AUC=0.73, 95% CI: 0.65-0.78), with a specificity of 78.41% and a sensitivity of 59.77%. The optimal cut-off value for the systemic immune inflammatory index (SII) was 654.37 (AUC=0.73, 95% CI: 0.66-0.78), with a specificity of 86.32% and a sensitivity of 62.11%. The optimal cut-off value for the IBI was 49.12 (AUC=0.82, 95% CI: 0.79-0.92), with a specificity of 85.36% and a sensitivity of 65.82%. LASSO regression analysis showed that there were 8 prognostic variables related to survival, including IBI, T stage, N stage, age, carcinoembryonic antigen (CEA), SII, PIV, and tumor grade. The results of univariate analysis showed that IBI ( HR=4.57, 95% CI: 3.82-5.32, P<0.001), T stage ( HR=2.54, 95% CI: 1.75-3.31, P<0.001), N stage ( HR=1.69, 95% CI: 1.15-2.21, P=0.032), CEA ( HR=1.38, 95% CI: 1.06-1.75, P=0.032), and tumor grade ( HR=1.87, 95% CI: 1.34-2.59, P=0.026) were prognostic factors for gastric cancer patients. The results of multivariate analysis showed that IBI ( HR=3.96, 95% CI: 3.51-4.48, P<0.001), T stage ( HR=2.31, 95% CI: 1.63-3.02, P=0.023), tumor grade ( HR=1.49, 95% CI: 1.12-1.83, P=0.042) were independent risk factors affecting the prognosis of gastric cancer patients. Compared with low-level IBI gastric cancer patients, the risk of death in high-level IBI patients was up to 3.96 times. Conclusion:IBI may be an important marker for diagnosis and prognosis prediction of gastric cancer, which has certain scientific and clinical value in the diagnosis and treatment of gastric cancer.

Objective To preliminarily investigate the related factors influencing the size of vestibular schwannomas.Methods The clinical data of patients with vestibular schwannomas who underwent retrosigmoid approach surgery at the department of neurosurgery of First Affiliated Hospital of Xinjiang Medical University from June 2013 to June 2023 were retrospectively analyzed.The tumor size of the patients was evaluated based on their preoperative imaging data.Univariate and multiple linear regression analyses were performed to explore the factors affecting the size of vestibular schwannomas.Results The tumor size of patients was ranging from 0.63 to 6.60 cm,with a median size of 2.97(2.20,3.80)cm.Univariate analysis showed that gender(P=0.010),ethnicity(P=0.001),age(P=0.049)and cystic solid tumor(P<0.001)were related to the size of vestibular schwannomas.Large-sized vestibular schwannomas were most commonly cystic-solid,and small and medium-sized vestibular schwannomas were most commonly solid.BMI,surgical side and place of residence were not correlated with the size of vestibular schwannomas(P>0.05).Multiple linear regression results showed that male(B=0.390,P=0.001)and Uyghur(B=0.611,P<0.001)patients were more likely to develop large tumors;with every 1-year increase in age,the maximum diameter of the tumor was reduced by an average of 0.011 cm(B=-0.011,P=0.027).Conclusion The gender,age,and ethnicity of patients are correlated with the size of vestibular schwannomas,and male,Uyghur,or younger patients were at higher risk of developing larger vestibular schwannomas.

Objective To analyze the clinical characteristics of patients with acute esophageal injuries in order to improve clinicians'diagnosis and treatment of such diseases.Methods The general data and treatment methods of 61 patients with acute esophageal injury from January 2013 to March 2023 were retrospectively analyzed.Results Majority of the patients with esophageal and cardia mucosal tear syndrome were male(72.2%),age(52.04±17.96)years,triggering factor was gastroscopy in 29 patients(53.7%),and vomiting of blood and black stools was the main clinical manifestation(63.0%),the average length of hospital stay was(6.39±3.53)d and 13(24.1%)patients had anaemic complications,blood transfusion was given to 8 patients(14.8%),39 patients(72.2%)were discharged after conservative treatment with transfusion,and only 15 patients(27.8%)required endoscopic hemostasis.1 case of esophageal hematoma combined with esophageal cardia mucosal tear syndrome was an elderly male patient with a history of hypertension,cerebral infarction,and long term use of oral aspirin,complicated by severe anemia,who was given desiprofloxacin to stop the hemostasis endoscopically,the total length of hospital stay was 22 d.4 patients with esophageal hematoma were young and middle-aged males,2 patients had a predisposing factor of poor diet prior to the onset of the disease,2 patients presented with vomiting of blood,1 with chest pain and 1 with a foreign body sensation in the throat,2 patients were discharged with endoscopic intervention,and the remaining 2 patients were discharged after conservative treatment.2 patients with spontaneous esophageal rupture were young and middle-aged males,clinical manifestations were chest tightness or retrosternal discomfort,and one patient had esophageal rupture with left-sided liquid pneumothorax,esophageal rupture repair+pleural adhesion branding+open thoracic hemostasis+intrathoracic foreign body removal was performed,and an esophageal stent was placed endoscopically after the operation,and the patient was discharged from the hospital after 52 d,in another case,the patient's esophageal fistula was small,and a three-lumen nutrient tube was placed under gastroscopic guidance,the patient's esophagus recovered well after 7 d,and the patient was discharged from the hospital.Conclusion Acute esophageal injury is a clinical emergency,among them,esophageal hematoma and spontaneous esophageal rupture are relatively rare.Prompt endoscopic clot removal is a viable option for patients with ruptured esophageal hematomas who have failed conservative treatment,and patients with spontaneous esophageal rupture who have surgically placed esophageal stents have good mucosal recovery.Clinicians need to be vigilant for patients with esophageal injuries that are associated with anemia,or even require blood transfusion,should make a clear diagnosis at an early stage,with timely endoscopic or surgical intervention to avoid progression of the disease.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To analyze the genetic subtypes of human immunodeficiency virus (HIV) and the prevalence of pretreatment drug resistance in the newly reported HIV-infected men in Guangxi. Methods The stratified random sampling method was employed to select the newly reported HIV-infected men aged≥50 years old in 14 cities of Guangxi from January to June in 2020.The pol gene of HIV-1 was amplified by nested reverse transcription polymerase chain reaction and then sequenced.The mutation sites associated with drug resistance and the degree of drug resistance were then analyzed. Results A total of 615 HIV-infected men were included in the study.The genetic subtypes of CRF01_AE,CRF07_BC,and CRF08_BC accounted for 57.4% (353/615),17.1% (105/615),and 22.4% (138/615),respectively.The mutations associated with the resistance to nucleoside reverse transcriptase inhibitors (NRTI),non-nucleoside reverse transcriptase inhibitors (NNRTI),and protease inhibitors occurred in 8 (1.3%),18 (2.9%),and 0 patients,respectively.M184V (0.7%) and K103N (1.8%) were the mutations with the highest occurrence rates for the resistance to NRTIs and NNRTIs,respectively.Twenty-two (3.6%) patients were resistant to at least one type of inhibitors.Specifically,4 (0.7%),14 (2.3%),4 (0.7%),and 0 patients were resistant to NRTIs,NNRTIs,both NRTIs and NNRTIs,and protease inhibitors,respectively.The pretreatment resistance to NNRTIs had much higher frequency than that to NRTIs (2.9% vs.1.3%;χ²=3.929,P=0.047).The prevalence of pretreatment resistance to lamivudine,zidovudine,tenofovir,abacavir,rilpivirine,efavirenz,nevirapine,and lopinavir/ritonavir was 0.8%, 0.3%, 0.7%, 1.0%, 1.3%, 2.8%, 2.9%, and 0, respectively. Conclusions CRF01_AE,CRF07_BC,and CRF08_BC are the three major strains of HIV-infected men≥50 years old newly reported in Guangxi,2020,and the pretreatment drug resistance demonstrates low prevalence.

Glioblastoma is the most common primary cranial malignancy, and chemotherapy remains an important tool for its treatment. Sanggenon C(San C), a class of natural flavonoids extracted from Morus plants, is a potential antitumor herbal monomer. In this study, the effect of San C on the growth and proliferation of glioblastoma cells was examined by methyl thiazolyl tetrazolium(MTT) assay and 5-bromodeoxyuridinc(BrdU) labeling assay. The effect of San C on the tumor cell cycle was examined by flow cytometry, and the effect of San C on clone formation and self-renewal ability of tumor cells was examined by soft agar assay. Western blot and bioinformatics analysis were used to investigate the mechanism of the antitumor activity of San C. In the presence of San C, the MTT assay showed that San C significantly inhibited the growth and proliferation of tumor cells in a dose and time-dependent manner. BrdU labeling assay showed that San C significantly attenuated the DNA replication activity in the nucleus of tumor cells. Flow cytometry confirmed that San C blocked the cell cycle of tumor cells in G_0/G_1 phase. The soft agar clone formation assay revealed that San C significantly attenuated the clone formation and self-renewal ability of tumor cells. The gene set enrichment analysis(GSEA) implied that San C inhibited the tumor cell division cycle by affecting the myelocytomatosis viral oncogene(MYC) signaling pathway. Western blot assay revealed that San C inhibited the expression of cyclin through the regulation of the MYC signaling pathway by lysine demethylase 4B(KDM4B), which ultimately inhibited the growth and proliferation of glioblastoma cells and self-renewal. In conclusion, San C exhibits the potential antitumor activity by targeting the KDM4B-MYC axis to inhibit glioblastoma cell growth, proliferation, and self-renewal.

Objective: To compare the differences to determine resting energy expenditure (REE) measured with indirect calorimetry and REE predicted by formula method and body composition analyzer in patients with decompensated hepatitis B cirrhosis, so as to provide theoretical guidance for the implementation of precision nutrition intervention. Methods: Patients with decompensated hepatitis B cirrhosis who were admitted to Henan Provincial People's Hospital from April 2020 to December 2020 were collected. REE was determined by the body composition analyzer and the H-B formula method. Results: were analyzed and compared to REE measured by the metabolic cart. Results A total of 57 cases with liver cirrhosis were included in this study. Among them, 42 were male, aged (47.93 ± 8.62) years, and 15 were female aged (57.20 ± 11.34) years. REE measured value in males was (1 808.14 ± 201.47) kcal/d, compared with the results calculated by the H-B formula method and the measured result of body composition, and the difference was statistically significant (P = 0.002 and 0.003, respectively). REE measured value in females was (1 496.60 ± 131.28) kcal/d, compared with the results calculated by the H-B formula method and the measured result of body composition, and the difference was statistically significant (P = 0.016 and 0.004, respectively). REE measured with the metabolic cart had correlation with age and area of visceral fat in men (P = 0.021) and women (P = 0.037). Conclusion: Metabolic cart use will be more accurate to obtain resting energy expenditure in patients with decompensated hepatitis B cirrhosis. Body composition analyzer and formula method may underestimate REE predictions. Simultaneously, it is suggested that the effect of age on REE in H-B formula should be fully considered for male patients, while the area of visceral fat may have a certain impact on the interpretation of REE in female patients.
