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 factors influencing the poor effect of short-term electrical spinal cord stimulation in the treatment of postherpetic neuralgia (PHN).Methods:The medical records of PHN patients of either sex, aged 40-85 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, who received short-term electrical spinal cord stimulation from July 2017 to July 2022, were retrospectively collected. The therapeutic effect was evaluated using the modified MacNab criteria at 3 months after operation, and the patients were divided into good efficacy group (excellent and good efficacy) and poor efficacy group (fair and poor efficacy). General information, disease course, lesion site, complicated diseases, ossification of the yellow ligament in the diseased spinal segment, severity of pain in the herpetic stage, standard antiviral therapy in the herpetic stage (for more than 7 days) and use of neurotrophic drugs in the herpetic stage (for more than 7 days) were collected. Multivariate logistic regression analysis was used to screen the influencing factors for the poor effect of electrical spinal cord stimulation in the treatment of PHN.Results:A total of 168 patients were eventually enrolled, among which 69 had poor curative effect, and the rate of poor curative effect was 41.1%. The results of multivariate logistic regression analysis showed that the patient′s age ( OR=2.230, P=0.015), course of disease ( OR=2.191, P=0.027), complication with diabetes mellitus( OR=8.859, P=0.010), ossification of ligamentum flavum at the same segment ( OR=6.602, P=0.019), severity of pain in the herpetic stage ( OR=5.788, P=0.038) and non-standard antiviral therapy in the herpetic stage ( OR=6.765, P=0.021) were the influencing factors for the poor effect of electrical spinal cord stimulation in the treatment of PHN. Conclusions:Age, course of disease, complication with diabetes mellitus, ossification of ligamentum flandum at the same segment, severity of pain in the herpetic stage and non-standard antiviral therapy in the herpetic stage are the factors influencing the poor effect of short-term electrical spinal cord stimulation in the treatment of PHN.

Objective:To evaluate the changes in the systemic circulation and microcirculation in the patients undergoing gastrointestinal surgery under general anesthesia in Xining area.Methods:A total of 27 patients, aged 18-60 yr, underwent gastrointestinal surgery under general anesthesia in Xining area (2 260 m), of long lived (more than two generations) Han nationality, with no alternating life between plateau and plain, with no cardiopulmonary abnormalities, were enrolled.Anesthesia was induced with midazolam, sufentanil, etomidate, and cisatracurium and maintained with propofol, remifentanil and cisatracurium.At 5 min before induction of anesthesia (T 1), 10 min after induction of anesthesia (T 2), 1 h after start of operation (T 3), immediately after the end of operation (T 4), and 30 min after recovery from anesthesia (T 5), systemic circulation indexes including cardiac output (CO), stroke volume (SV), stroke volume variability (SVV), systemic vascular resistance index (SVRI), and mean arterial pressure (MAP) and heart rate (HR) were recorded, and sublingual microcirculation indexes including total vascular density (TVD), perfused vessel density (PVD), portion of perfused vessels (PPV), and microvascular flow index (MFI) were determined by sidestream dark field imaging. Results:Systemic circulation Compared with the baseline at T 1, CO and HR were significantly decreased at T 2-4, SVV was decreased at T 5, SVRI was increased at T 3 and T 4, and MAP was decreased at T 2 ( P<0.05). Compared with those at T 2, CO and SV were significantly increased at T 5, SVV was decreased at T 5, SVRI was increased at T 3 and T 4, and MAP was increased at T 4 and T 5 ( P<0.05). Compared with those at T 3, SV was significantly decreased at T 4, CO was increased at T 5, and SVV and SVRI were decreased at T 5 ( P<0.05); Compared with those at T 4, CO, SV and HR were significantly increased at T 5, and SVV and SVRI were decreased at T 5 ( P<0.05). Microcirculation Compared with those at T 1, TVD, PVD, PPV and MFI were significantly decreased at T 2-4, and PPV and MFI were decreased at T 5 ( P<0.05). Compared with those at T 2, TVD was significantly increased at T 5, PVD was increased at T 4 and T 5, and PPV was increased at T 3 and T 4 ( P<0.05). TVD was significantly higher at T 5 than at T 3( P<0.05). TVD was significantly higher at T 5 than at T 4 ( P<0.05). Conclusions:The density of microcirculation and blood flow rate are decreased after induction of general anesthesia and during anesthesia operation, which are most significant at the initial stage after induction, and decoupling between systemic circulation and microcirculation occurs during operation and anesthesia resuscitation in the patients at high altitude.

Objective:To investigate the relationship between serum uric acid (SUA) and 3-month outcomes in patients with acute ischemic stroke undergoing intravenous thrombolysis.Methods:A total of 386 patients with acute ischemic stroke received intravenous thrombolysis therapy from 1 January 2017 to 31 December 2019 in the Affiliated Hospital of Lianyungang, Xuzhou Medical University were enrolled prospectively. The National Institute of Health Stroke Scale (NIHSS) was used to evaluate the severity of stroke. The functional outcome was evaluated by the modified Rankin Scale at discharge or 3 months after onset. Pearson′s correlation was used to assess the relationship between SUA and NIHSS scores at baseline and discharge. Propensity score matching was used to balance confounding factors. Multivariate logistic regression model was used to identify the correlation between SUA and prognostic outcome after thrombolysis.Results:A total of 386 eligible patients were included. Two hundred and thirty patients (59.6%) had good outcomes in the follow-up after 3 months. The levels of SUA are negatively associated with the NIHSS score at discharge ( r=-0.171, P=0.003). A positive correlation was observed between the levels of SUA and the difference of NIHSS at baseline and discharge ( r=0.118, P=0.032). Patients were divided into three groups according to the quartile of SUA. Multivariate logistic regression analysis showed that high SUA levels were independently associated with good outcome three months after stroke ( OR=0.421, 95% CI 0.327-0.541, P<0.001). Conclusion:In patients with acute ischemic stroke, elevated SUA levels can predict better recovery and short-term outcomes in patients undergoing intravenous thrombolysis.

Objective:To investigate the predictive value of stress hyperglycemia for the functional outcomes in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to the Affiliated Hospital of Lianyungang, Xuzhou Medical University from September 1, 2019 to December 31, 2020 were enrolled prospectively. The glucose to glycated hemoglobin ratio (GAR) was used to express stress hyperglycemia. The functional outcome was evaluated by the modified Rankin Scale at 3 month after discharge, 0-2 was defined as a good outcome and >2 as a poor outcome. Multivariate logistic regression analysis was used to determine the independent related factors of functional outcome. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of GAR for poor functional outcome. Results:A total of 1 286 patients with AIS were included. Their median age was 67 years old, and 762 were males (59.3%). The median baseline National Institutes of Health Stroke Scale (NIHSS) score was 2. The median fasting blood glucose level was 5.48 mmol/L, the median glycosylated hemoglobin was 6.00%, and the median GAR was 0.92. Eight hundred and twelve patients (63.1%) had good outcomes and 474 (36.9%) had poor outcomes. The GAR in the good outcome group was significantly lower than that in the poor outcome group (0.86 vs. 1.03; P<0.001). All patients were divided into 4 groups (GAR1, GAR2, GAR3, and GAR4) according to the GAR quartile from low to high. Multivariate logistic regression analysis showed that after adjusting for relevant confounding factors, GAR4 (taking the GAR1 as a reference, odds ratio [ OR] 8.896, 95% confidence interval [ CI] 5.775-13.702; P<0.001), age ( OR 1.041, 95% CI 1.027-1.055; P<0.001) and baseline NIHSS score classification ( OR 25.898, 95% CI 14.221-47.163; P<0.001) were closely associated with the poor outcomes at 3 months. Further subgroup analysis showed that the higher level of GAR was significantly and independently correlated with the poor functional outcome, regardless of whether the patients had diabetes or not. The ROC curve analysis showed that the area under the curve of GAR predicting poor outcome at 3 months was 0.705 (95% CI 0.675-0.735; P<0.001), and the predictive value was significantly higher than that of glycosylated hemoglobin and fasting blood glucose. When the cut-off value of GAR was 0.97, the Yoden index was the largest, which was 0.370. The sensitivity and specificity of its predicting the poor outcome at 3 months were 61.6% and 75.4%. Conclusion:Whether or not diabetes is present, GAR is an independent predictor of the poor outcomes in patients with AIS.

Issues caused by maxillofacial tumours involve not only dealing with tumours but also repairing jaw bone defects. In traditional tumour therapy, the systemic toxicity of chemotherapeutic drugs, invasive surgical resection, intractable tumour recurrence, and metastasis are major threats to the patients' lives in the clinic. Fortunately, biomaterial-based intervention can improve the efficiency of tumour treatment and decrease the possibility of recurrence and metastasis, suggesting new promising antitumour therapies. In addition, maxillofacial bone tissue defects caused by tumours and their treatment can negatively affect the physiological and psychological health of patients, and investment in treatment can result in a multitude of burdens to society. Biomaterials are promising options because they have good biocompatibility and bioactive properties for stimulation of bone regeneration. More interestingly, an integrated material regimen that combines tumour therapy with bone repair is a promising treatment option. Herein, we summarized traditional and biomaterial-mediated maxillofacial tumour treatments and analysed biomaterials for bone defect repair. Furthermore, we proposed a promising and superior design of dual-functional biomaterials for simultaneous tumour therapy and bone regeneration to provide a new strategy for managing maxillofacial tumours and improve the quality of life of patients in the future.

The efficacy of TESSYS technique in treating the far lateral lumbar disc herniation was analyzed retrospectively.From June 2017 to June 2019, 11 patients with far lateral lumbar disc herniation underwent surgery were selected as F group, and 13 patients with central or paracentral lumbar disc herniation were selected as L group, regardless of gender, with the age of 51-66 yr.Preoperative selective nerve root block was performed under the guidance of ultrasound to determine the diseased disc, and then discectomy was performed using TESSYS technique in both groups.Pain was assessed using Visual Analogue Scale score at l day before surgery and 3 days and 1, 3 and 6 months after surgery.Patient′s function was assessed by using the Oswestry Disability Index at l day before surgery and 6 months after surgery.The therapeutic effect was evaluated using the modified Macnab criteria at 6 months after surgery.Compared with group L, no significant change was found in Visual Analogue Scale scores at each time point after surgery, Oswestry Disability Index scores at 6 months after surgery, and Macnab outcome grade at 6 months after surgery in group F ( P>0.05). In conclusion, TESSY technique can be used to treat the far lateral lumbar disc herniation.

Objective: To assess the relationship between hemoglobin A₁c (HbA₁c) and hemorrhagic cerebral infarction (HI) in patients with acute cerebral infarction. Methods: From January 2014 to June 2016, in the Lianyungang Hospital Affiliated to Xuzhou Medical University, 426 patients with acute anterior circulation infarction were included. The blood sugar status before stroke was expressed by HbA₁c. HbA₁c and fasting blood glucose (FBG) were measured on the second day after admission. The National Institutes of Health Stroke Scale (NIHSS) was used to assess the severity of neurological function at admission. The modified Rankin scale (mRS) was used to evaluate the prognosis at discharge. CT or MRI/SWI examination was performed to determine whether there was HT. Logistic regression was used to evaluate the risk factors for HT and short-term prognosis after cerebral infarction. Results: Of the 426 patients enrolled, 93 (21.8%) appeared HT, 60 (14.1%) had hemorrhagic cerebral infarction (HI) and 33 (7.7%) had parenchymal hemorrhage (PH). Multivariate analysis showed that HbA₁c and infarct volume were independent predictor of HT. When patients were grouped according to fasting blood glucose (FBG<7.8 mmol/L or ≥ 7.8 mmol/L), the predictive effect of HbA₁c on HT was found in both groups. In multiple Logistic regression analysis, HbA₁c was also a predictor of poor prognosis after stroke (OR=1.482, 95% CI 1.228 -1.788). Conclusions In patients with ischemic stroke, elevated HbA₁c is independently associated with post-infarction HT, and this result doesn′t change even in patients with well-controlled blood glucose. HbA₁c is also a predictor of poor prognosis after stroke. These findings are important for blood glucose management in patients with diabetes and acute anterior circulation infarction.

Objective: To explore the mechanism of llinc00052 regulating Wnt pathway affecting invasion and metastasis of gastric cancer. Methods: SGC-7901 cells were selected from gastric cancer cell lines, and siRNAs related to INC0005 and had invasion and metastasis effects in gastric cancer cells were screened by binding of IncRNA expression profiles to qRT-PCR.Ilinc00052 and miRNA expression changes were studied by in vitro cell transfection experiments.Through molecular experiments, the expression of llinc00052 and the effect on Wnt/β-catenin expression were investigated to explore whether llinc00052 could affect the invasion and metastasis of gastric cancer cells by regulating miRNAs affecting Wnt/β-catenin signaling pathway. Results: Transwell chamber test showed that the number of transmembrane cells in the untransfected plasmid group was (134.10±4.29), and the number of transmembrane cells in the overexpressed llinc000522 plasmid group was (169.24±6.99)(t=8.956, P=0.001). The scratch test showed that the migration distance in the llinc000522 overexpression transfection plasmid group was significantly higher than that in the no-load plasmid transfection group(r=0.907, P<0.01). The clone formation rate of llinc000522 overexpressed transfected plasmid group was significantly higher than that of the empty plasmid group[(92.75±6.32)% vs.(73.34±9.14)%](t=5.998, P<0.05). Compared with the transfection of blank plasmid, the expressions of Wnt1, Wnt3a, Wnt2 and β-catenin mRNA in the llinc000522 overexpression transfection group were significantly up-regulated(P<0.05), while the miRNA transfection group had no significant effect on the expression.The expressions of Wnt1, Wnt3a, Wnt2, and β-catenin mRNA were significantly increased [(1.82±0.11), (1.52±0.15), (1.42±0.21), (1.71±0.19)](P<0.05), but their expressions were still lower than those of the genes transfected with llinc000522 alone.Compared with the blank plasmid transfection, the expressions of Wnt1, Wnt3a, Wnt2 and β-catenin protein in the llinc000522 overexpression transfection group were significantly up-regulated(all P<0.05), while the miRNA transfection group had no significant effect on its expression.The protein expressions of Wnt1, Wnt3a, Wnt2 and β-catenin were also significantly increased[(1.53±0.09), (1.4±0.21), (1.33±0.07), (1.47±0.19)](P<0.05), but their expressions were still lower than those of the gene transfected with llinc000522 alone. Conclusion In gastric cancer cells, llinc00052 can affect the invasion and metastasis of gastric cancer by regulating the level of miRNA and affecting the Wnt/β-catenin pathway.
