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 characteristics of blood lipid metabolism in patients with Wilson's disease(WD)and understand the influencing factors of abnormal blood lipid.Methods The clinical data of 170 patients with WD and 59 healthy people were collected from June 2021 to March 2023,the blood lipids of the two groups were compared.To compare the characteristics of blood lipid metabolism in WD patients with different gender,age,body mass index(BMI)and disease types.According to whether the blood lipid was abnormal or not,WD patients were divided into normal blood lipid group and abnormal blood lipid group,and the biochemical indexes of the two groups were compared.The general situation and biochemical indicators were included in the single factor regression analysis,and the related factors that might affect blood lipid metabolism were screened out.The related factors of single factor screening were included in multivariate Logistic regression analysis to determine the abnormal factors affecting blood lipid.Results The triglyceride(TG)level of WD patients was lower than that of healthy controls,the difference was statistically significant(P<0.05).The rate of dyslipidemia in WD patients was 40.59%.Low density liporotein cholestrol in female WD patients was significantly lower than that in male WD patients(P<0.05).The values of BMI,alanine aminotransferase(ALT)and uric acid(UA)in dyslipidemia group of WD patients were significantly higher than those in normal group(all P<0.05).Multivariate Logistic regression analysis showed that BMI 24～28(OR=4.526,P<0.05),BMI>28(OR=6.360,P<0.05),UA(OR=1.006,P<0.01)and hyaluronic acid(HA)(OR=1.003,P<0.01)were associated with the high risk of dyslipidemia,with statistical significance.Conclusions WD patients have a high incidence of abnormal lipid metabolism,mainly with low high density liporotein cholestrol and high TG.The dyslipidemia in WD patients is affected by many factors.BMI,UA and HA are independent risk factors for dyslipidemia in WD patients.

Objective:To investigate the clinical efficiency of lumbar hernia repair based on path planning.Methods:The retrospective and descriptive study was conducted. The clinical data of 35 patients with lumbar hernia who were admitted to The First Affiliated Hospital of University of Science and Technology of China from November 2016 to March 2024 were collected. There were 14 males and 21 females, aged (61±8)years. According to preoperative computerized tomography examination of the hernia defect diameter, patients with a defect diameter <4 cm underwent enhan-ced field laparoscopic total extraperitoneal repair (eTEP), patients with a defect diameter of 4-8 cm underwent laparoscopic partial extraperitoneal repair (TAPE), and patients with a defect diameter >8 cm underwent open preperitoneal mesh repair (Sublay). Measurement data with normal distribu-tion were represented as Mean± SD, and comparison of three groups were conducted using the one-way ANOVA or Kruskal Wallis test, and Bonferroni correction was used for pariwise comparison. Measurement data with skewed distribution were represented as M(range). Count data were descri-bed as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Results:(1) Operation conditions. Of 35 patients, there were 15 cases undergoing eTEP, of 7 males and 8 females and 12 cases of left hernia and 3 cases of right hernia, with operation time of (92±44)minutes and the duration of postoperative hospital stay of (5.6±2.8)days. There were 17 cases undergoing TAPE, of 5 males and 12 females and 9 cases of left hernia, 7 cases of right hernia and 1 case of bilateral hernia, with operation time of (114±56)minutes and the duration of postoperative hospital stay of (6.4±3.0) days. There were 3 cases undergoing Sublay, of 2 males and 1 female and 1 case of left hernia and 2 cases of right hernia, with operation time of (150±55)minutes and the duration of postoperative hospital stay of (12.3±7.8)days. There were significant differences in the duration of postoperative hospital stay among the three groups ( F=4.83, P<0.05). (2) Follow-up. All 35 patients were followed up for 40.5(range, 3.0-91.0)days. None of patient underwent postoperative complications such as serous swelling, incision infection, intestinal fistula, intestinal obstruction, or puncture hematoma, and no recurrence of lumbar hernia occurred. One patient who underwent TAPE had postoperative abdominal distension, and was cured by symptomatic treatment. Cases with acute pain within postoperative 3 months were 0, 5, 2 in patients undergoing eTEP, TAPE, Sublay, respectively, showing significant differences among them ( χ2=8.69, P<0.05). Results of pariwise comparison showed that there was a significant difference in acute pain within postoperative 3 months between patients undergoing eTEP and Sublay ( P<0.05), and there was a significant difference in acute pain within postoperative 3 months between patients undergoing eTEP and TAPE ( P<0.05); Cases with chronic pain after postoperative 3 months were 0, 1, 1 in patients undergoing eTEP, TAPE, Sublay, respectively, showing no significant difference among them ( χ2=4.00, P>0.05). Conclusion:It is safe and feasible to formulate the surgical method according to the defect diameter of lumbar hernia.

Background and Aims:Parastomal hernia is a common complication after colostomy,with a high incidence rate.Laparoscopic Sugarbaker repair is currently the mainstream surgical approach for treating parastomal hernia.However,compared to other abdominal wall hernia repair techniques,the recurrence rate of parastomal hernia after laparoscopic Sugarbaker repair remains relatively high.Furthermore,the recurrence rate after surgery for recurrent parastomal hernias is significantly higher than that after the initial surgery,with inadequate lateral mesh coverage being one of the major contributing factors.This study was performed to analyze the efficacy of two-point mark-guided laparoscopic Sugarbaker repair in patients with terminal colostomy parastomal hernia,so as to provide evidence-based references for clinical practice. Methods:The clinical data of 120 patients with terminal colostomy parastomal hernia,who underwent laparoscopic Sugarbaker repair guided by the two-point mark of mesh at the Department of Hernia and Obesity Surgery,the First Affiliated Hospital of the University of Science and Technology of China,from January 2015 to December 2023,were retrospectively collected.The parastomal hernias were classified according to the European Hernia Society classification.Postoperative symptomatic and radiological recurrence rates were analyzed,as well as the incidence of complications such as bowel obstruction,stoma infection,and intestinal fistula in recurrent and non-recurrent patients. Results:Of the 120 patients,2(1.7％)were lost to follow-up.The mean follow-up duration was 48(6-96)months.The postoperative symptomatic recurrence rate was 5.1％(6/118),and the radiological recurrence rate was 6.8％(8/118).There were no statistically significant differences between recurrent(n=8)and non-recurrent patients(n=110)in terms of sex,age,body mass index(BMI),or hernia defect size(all P＞0.05),but the operative time in recurrent patients was longer than that in non-recurrent patients(P＜0.05).The overall postoperative complication rate was 8.5％(10/118),including stoma skin-mucosa separation(3 cases),stoma infection(2 cases),delayed bowel obstruction(2 cases),early bowel obstruction(1 case),hernia sac effusion(1 case),and delayed fistula formation in the hernia sac cavity(1 case).According to the Clavien-Dindo classification,there were 6 cases of grade Ⅱ,3 cases of gradeⅢa,and 1 case of grade Ⅳ complications.There were no statistically significant differences between patients with and without complications regarding sex,BMI,hernia defect size,operative time,and comorbidities(all P＞0.05);however,patients with complications were older than those without(P＜0.05). Conclusion:The application of laparoscopic Sugarbaker repair under the guidance of two-point mesh identification can effectively reduce the recurrence rate of parastomal hernia and It has high clinical applicability.

Objective To investigate the ideas for the clinical and genetic diagnosis of hepatolenticular degeneration （HLD） occurring in two consecutive generations. Methods The information on history of present illness， past history， and family history were collected from three patients with HLD who were admitted to our department from June 2017 to July 2023， and their first-degree relatives who might have this disease were examined in terms of liver function， serum ceruloplasmin （CP）， basal 24-hour urinary copper excretion （urinary Cu）， Kayser-Fleischer ring （KFR） of the cornea， abdominal ultrasound， and ATP7B gene testing. Results Among the parents or children of the probands in these three families， two were found to have elevated serum aminotransferases， three had a reduction in CP and an increase in urinary Cu， and 1 had fatty liver； all of them had compound heterozygous mutations in the ATP7B gene， and all tested negative for KFR. This study identified three families with HLD occurring in two consecutive generations and found a new pathogenic mutation. Conclusion CP， KFR， or abdominal ultrasound has certain limitations in screening pre-symptomatic HLD； urinary Cu test has a good sensitivity， and genetic testing can further improve the accuracy of diagnosis. Due to the high carrying rate of ATP7B pathogenic mutations in the population with HLD， HLD occurring in two consecutive generations should be taken seriously in clinical practice.

Background: and Purpose The association of dyslipidemia with stroke has been inconsistent, which may be due to differing associations within etiological stroke subtypes. We sought to determine the association of lipoproteins and apolipoproteins within stroke subtypes. Methods: Standardized incident case-control STROKE study in 32 countries. Cases were patients with acute hospitalized first stroke, and matched by age, sex and site to controls. Concentrations of total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A1 (apoA1), and apoB were measured. Non-HDL-C was calculated. We estimated multivariable odds ratio (OR) and population attributable risk percentage (PAR%). Outcome measures were all stroke, ischemic stroke (and subtypes), and intracerebral hemorrhage (ICH). Results: Our analysis included 11,898 matched case-control pairs; 77.3% with ischemic stroke and 22.7% with ICH. Increasing apoB (OR, 1.10; 95% confidence interval [CI], 1.06 to 1.14 per standard deviation [SD]) and LDL-C (OR, 1.06; 95% CI, 1.02 to 1.10 per SD) were associated with an increase in risk of ischemic stroke, but a reduced risk of ICH. Increased apoB was significantly associated with large vessel stroke (PAR 13.4%; 95% CI, 5.6 to 28.4) and stroke of undetermined cause. Higher HDL-C (OR, 0.75; 95% CI, 0.72 to 0.78 per SD) and apoA1 (OR, 0.63; 95% CI, 0.61 to 0.66 per SD) were associated with ischemic stroke (and subtypes). While increasing HDL-C was associated with an increased risk of ICH (OR, 1.20; 95% CI, 1.14 to 1.27 per SD), apoA1 was associated with a reduced risk (OR, 0.80; 95% CI, 0.75 to 0.85 per SD). ApoB/A1 (OR, 1.38; 95% CI, 1.32 to 1.44 per SD) had a stronger magnitude of association than the ratio of LDL-C/HDL-C (OR, 1.26; 95% CI, 1.21 to 1.31 per SD) with ischemic stroke (P<0.0001). Conclusions The pattern and magnitude of association of lipoproteins and apolipoproteins with stroke varies by etiological stroke subtype. While the directions of association for LDL, HDL, and apoB were opposing for ischemic stroke and ICH, apoA1 was associated with a reduction in both ischemic stroke and ICH. The ratio of apoB/A1 was the best lipid predictor of ischemic stroke risk.

Objective:To study the Epstein-Barr virus (EBV) activity and its clinical characteristics in patients with hemorrhagic fever with renal syndrome (HFRS). Methods:From January 2016 to August 2017, patients with HFRS who were hospitalized in the First Affiliated Hospital of Harbin Medical University were routinely tested by EBV serology, and were divided into two groups according to their presence or absence of EBV infection, namely EBV active group and non-EBV active group. The clinical data between the two groups were compared and analyzed by SPSS 18.0.Results:A total of 188 HFRS patients were enrolled, including 73 cases in EBV active group and 115 cases in non-EBV active group. The EBV active rate of HFRS patients was 38.83% (73/188). The incidences of lumbago [57.53% (42/73) vs 42.61% (49/115)], abdominal pain [42.47% (31/73) vs 20.00% (23/115)], skin and mucosa congestion [57.53% (42/73) vs 39.13% (45/115)], and conjunctiva edema [50.68% (37/73) vs 28.70% (33/115)] in EBV active group were significantly higher than those in non-EBV active group (χ 2 = 3.983, 11.008, 6.083, 9.239, P < 0.05). There were 10, 7 and 43 patients with acute kidney injury (AKI) stage 1, 2 and 3 in EBV active group and 5, 13 and 53 patients in non-EBV active group. Degree of AKI in EBV active group was higher than that in non-EBV active group, and the difference was statistically significant (χ 2 = 12.615, P < 0.05). In EBV active group, the proportion of patients whose renal function recovery over 15 days [23.29% (17/73)] and white blood cell count [11.26 (3.39 ~ 54.23) × 10 9/L] were significantly higher than those in non-EBV active group [6.96% (8/115), 10.03 (2.91 ~ 66.99) × 10 9/L], and the differences were statistically significant (χ 2 = 10.330, Z = - 2.003, P < 0.05). Conclusion:HFRS patients may cause latent EBV activity, complicate their clinical features, cause severe renal damage and prolong the recovery time of renal function.

Objective:To understand the knowledge and behavior changes of pregnant women on iodine deficiency disorders (IDD) prevention and treatment in iodine deficiency areas in Anhui Province before and after the implementation of the intervention measures, and to provide a scientific basis for pregnant women's iodine nutrition improvement.Methods:From March to December 2018, from Lujiang County, an iodine deficiency area in Anhui Province, Lucheng and Nihe towns were selected as the survey sites. Relying on the township health centers, pregnant women in early pregnancy (≤12 weeks) were selected as the survey subjects, and long-term follow-up was conducted. The edible salt samples of pregnant women in early pregnancy were collected and salt iodine content was detected by direct titration method. The urine samples of pregnant women in the morning in early, middle (13 - 28 weeks) and late pregnancies (≥29 weeks) were collected, urinary iodine content was determined by arsenic-cerium catalytic spectrophotometry. Baseline questionnaire survey was conducted for pregnant women in early pregnancy, mainly including basic information, IDD prevention and treatment knowledge (pregnant women prone to iodine deficiency, the harm of iodine deficiency in pregnant women, suitable iodine supplement methods for pregnant women and foods with high iodine content), and the consumption frequency of iodine-rich foods. After the baseline survey, the knowledge publicity on IDD prevention and treatment was carried out in townships, and iodine-rich foods such as kelp and laver were recommended to supplement iodine. The intervention activities lasted for 6 months, and retrospective questionnaire survey was conducted on pregnant women in late pregnancy.Results:A total of 128 edible salt samples were collected from the families of pregnant women in early pregnancy, and the median salt iodine was 21.5 mg/kg. The iodized salt coverage rate was 99.2% (127/128), the qualified rate of iodized salt was 98.4% (125/127), and the consumption rate of qualified iodized salt was 97.7% (125/128). A total of 129, 95 and 70 urine samples were collected from pregnant women in early, middle and late pregnancies, the medians urinary iodine were 179.0, 185.5 and 189.7 μg/L, respectively, all of which were at the appropriate iodine level. The total awareness rates of IDD prevention and treatment before and after intervention were 22.4% (28/125) and 64.6% (82/127), respectively, and the difference was statistically significant (χ 2 = 45.538, P < 0.01). Compared with the awareness rates before the intervention, the awareness rates of the harm of iodine deficiency in pregnant women, suitable iodine supplement methods for pregnant women and foods with high iodine content were all higher after the intervention ( P < 0.01). There were statistically significant differences in the frequency of eating kelp, laver and other iodine-rich foods among pregnant women in early, middle and late pregnancies (χ 2 = 163.170, 102.373, P < 0.01). Before the intervention, 57 (45.2%) pregnant women had not eaten kelp, which decreased to 1 (0.8%) pregnant woman after the intervention. Before the intervention, 72 (57.1%) pregnant women had not eaten laver and other iodine-rich foods, which decreased to 7 (5.5%) pregnant women after the intervention. Conclusions:After the intervention, the awareness rate of IDD prevention and treatment knowledge and the frequency and proportion of iodine-rich foods consumption among pregnant women in iodine deficiency areas in Anhui Province have increased significantly. It is recommended to carry out publicity and education on IDD prevention and treatment knowledge in early pregnancy.

Objective:To investigate the pathology characteristics, so as to provide treatment experience of primary cardiac tumors for pediatric patients.Methods:A retrospective study was conducted for 135 patients with primary cardiac tumor between January 2004 and December 2017 in Shanghai Children′s Medical Center.The median age was 0.54 years (range, 0-14.36 years). Single tumor was discovered in 61 cases and multiple rumors were found in 74 cases.Forty-five patients presented obvious clinical symptoms, 4 patients with mild symptoms and 86 patients without symptoms.Forty-one patients underwent surgical treatment, including complete resection of the tumor in 24 cases, partial resection in 16 cases and heart transplantation in 1 case.Concomitant valvuloplasty was required in 13 patients.Ninety-four patients did not receive surgical treatment.Results:A total of 40 patients underwent surgical treatment in Shanghai Children′s Medical Center.Three patients died of low cardiac output (in-hospital mortality: 7.5%), and 2 patients recovered from postoperative low cardiac output.The hemodynamic status was stable in the remaining 35 cases.One patient who received heart transplantation in another hospital survived and had good cardiac function during 24 months follow-ups.There were no significant differences in the survival rate between partial resection and complete resection of benign tumors.One late death was observed in patients with malignant tumors for 2 years after operation.Surveillance was kept in 94 non-surgical patients, among whom 1 case died for the abandon of surgery and 1 case died when waiting for heart transplantation.Other 2 patients were waiting for heart transplantation and other 90 patients had no hemodynamic disorder.Conclusion:Most of primary cardiac tumors are benign and long time follow-up should be able to get on for pediatric patients.When patients develop hemodynamical obstruction, arrhythmia or malignant tumor, surgical treatment is necessary.The principle of surgical therapy in these patients is to restore normal hemodynamic status, instead of completely removing tumor.Heart transplantation is potentially the only way for patients whose tumor cannot be resected.

Objective:To establish an automatic colorimetric method for determination of iodine in drinking water by enzyme-labeled instrument (hereinafter referred to as this method).Methods:The water iodine was measured in the range of 0 - 10 μg/L and 0 - 100 μg/L, experiments were carried out on linear relationship, detection limit, precision and accuracy of this method. And the results were compared with the National Reference Laboratory for Iodine Deficiency Disorders recommended arsenic cerium catalytic spectrophotometry method.Results:In the range of 0 - 10 μg/L and 0 - 100 μg/L, all│ r│ > 0.999 0, the detection limits were 0.6 and 1.1 μg/L (samples were 200 and 100 μl), respectively; the relative standard deviation ( RSD) of water samples of low, medium and high iodine mass concentrations were < 3%, the recovery rates ranged from 92.5% to 108.3% and 93.2% to 108.9%, with a total average recovery of 100.0% and 100.3%, respectively. This method and arsenic cerium catalytic spectrophotometry method were used to detect 40 water samples in the range of 0 - 10 μg/L and 0 - 100 μg/L, there was no significant difference in water iodine content between the two methods ( t = 0.99, P > 0.05). Conclusion:This method has good linear curve relationship for determination of water iodine content, good precision and high accuracy, and it is suitable for wide application.
