Objective To explore the diagnostic value of urinary liquid-based cytology(LBC)targeted fluorescence in situ hybridization(FISH)for urothelial carcinoma of the bladder.Methods Nuclear matrix protein 22(NMP22)detection,urinary LBC and FISH were performed in 128 patients.The sensitivity and specificity of the three kinds of tests were analyzed with postoperative pathological results as the gold standard.Results The sensitivity of NMP22,urinary LBC and FISH was 61.11％,79.17％and 82.46％,the specificity was 57.14％,73.21％and 86.67％,respectively.The sensitivity of NMP22 and urinary LBC in detecting high BUC was better than that of low BUC,and the difference was statistically significant(P=0.01,P=0.03).There was no significant difference in the sensitivity of the three tests for the diagnosis of muscle-invasive bladder cancer and non muscle-invasive bladder cancer(P≥0.05).Conclusion Urinary LBC targeted FISH has high sensitivity and specificity in the diagnosis of urothelial carcinoma of the bladder and low-grade urothelial carcinoma.It can be an important method for the early screening and diagnosis of bladder cancer.

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 explore the gene expression profile in paraspinal muscle degeneration(PMD)and identify key ferroptosis genes.Methods RNA sequencing was performed on paraspinal muscle tissue of 3 normal and 3 PMD patients respectively to obtain differentially expressed genes.Through protein-protein interaction(PPI)and gene functional enrichment analysis,the intersection of ferroptosis genes was identified to identify key hub genes associated with ferroptosis.The diagnostic value for PMD disease was analyzed by receiver operating characteristic(ROC)curves.Results A total of 292 differentially expressed genes were identified in PMD.Among them,125 genes were significantly downregulated and 167 genes were significantly upregulated.Bioinformatics analysis revealed that 14 differentially expressed genes were associated with ferroptosis.Among them,ferroptosis genes MUC1,ATF3 and CDKN1A were key hub genes with good specificity and sensitivity for diagnosing PMD.Functional enrichment analysis revealed that they may mediate the occurrence and progression of PMD by regulating cell apoptosis,ferroptosis and skeletal muscle tissue development and differentiation.Conclusion Ferroptosis genes MUC1,ATF3 and CDKN1A can serve as biomarkers for diagnosing PMD,providing theoretical basis for decoding the pathological mechanism of PMD and developing new drugs.

Objective:To explore the predictive value of the change rate of parathyroid hormone (PTH) after total thyroidectomy (TT) for hypoparathyroid function.Methods:A total of 182 patients with thyroid tumor who underwent TT from Jan. 2018 to Jun. 2023 in the Department of Otolaryngology, Head and Neck Surgery, Second Hospital of Shanxi Medical University were retrospectively selected as the study objects. The clinical and surgical data of the patients were collected, and the key factors associated with postoperative hypoparathyroidism were screened by multi-factor analysis. The change rate of serum PTH was calculated during perioperative period (before operation, at the end of operation, 1 and 3 days after operation). Receiver operator curve (ROC) was used to analyze the predictive value of PTH change rate in all patients.Results:Whether temporary hypoparathyroidism (THP) or permanent hypoparathyroidism (PHP), both were closely related to TT+ bilateral central lymph node dissection ( χ2=33.764, 9.235, P < 0.05) and parathyroid resection ( χ2=6.512, 58.999, P < 0.05). The change rate of PTH in HP patients was significantly higher than that in normal patients ( F=15.993, 16.830, 19.024, P < 0.05), and on the first and third day after surgery, the change rate of PTH in PHP patients was significantly higher than that in THP patients ( t=7.955, 9.023, P < 0.05). The predicted area under curve (AUC) of THP or PHP in different patient populations is different with the change rate of PTH in different periods. For patients with TT+ bilateral central lymph node dissection and parathyroidectomy, the change rate of PTH at the end of surgery was significantly higher than the change rate of PTH at 3 days after surgery for the AUC with PHP ( Z=5.433, 4.923, P < 0.05) . Conclusion:Perioperative PTH has good predictive value for THP and PHP in TT patients, especially in TT+ bilateral central lymph node dissection and parathyroidectomy.

Objective To investigate the clinical effect of Jiaotai Shugan decoction in adjuvant treatment of type 2 diabetes mellitus(T2DM)complicated with depression with liver qi stagnation type.Methods From June 2022 to June 2023,90 patients with T2DM complicated with depression with liver qi stagnation type treated in the Second People's Hospital of Lishui City were selected,who were randomly divided into control group and observation group,with 45 cases in each group.Both groups were treated with basic treatment of diabetes,control group was given escitalopram to improve the emotion,while observation group was further given Jiaotai Shugan decoction.After 8 weeks,the clinical effective rate were evaluated by Hamilton depression scale-24(HAMD-24)and patient health questionnaire-9(PHQ-9)scores,the levels of 5-hydroxytrytamine(5-HT),noradrenaline(NE),brain-derived neurotrophic factor(BDNF),fasting blood glucose(FPG),2-hour postprandial blood glucose(2hPG)and haemoglobinA1c(HbA1c)were detected,and adverse reactions were recorded.Results The clinical total effective rates of observation group was higher than that of control group,and the difference was statistically significant(P＜0.05).8 weeks after treatment,HAMD-24 and PHQ-9 scores of observation group were lower than those of control group(P＜0.01).The levels of 5-HT,NE and BDNF of observation group were higher than those of control group(P＜0.01).The levels of FPG,2hPG and HbA1c in observation group were lower than those in control group(P＜0.01);There was no significant difference in adverse reactions between two groups(P＞0.05).Conclusion Modified Jiaotai Shugan decoction is effective in treating T2DM complicated with depression with liver qi stagnation type,can reduce HAMD-24 and PHQ-9 scores,increase the levels of 5-HT,NE,BDNF,and reduce the levels of FPG,2hPG,HbA1c.There was no obvious adverse reactions.

Abstract: Objective To investigate the clinical features and risk factors for severe tsutsugamushi disease, so as to provide reference for diagnosis and differentiation of severe tsutsugamushi disease as soon as possible. Methods The clinical data of 178 cases of inpatients with tsutsugamushi disease admitted to the Guangzhou Eighth People's Hospital, Guangzhou Medical University from January 2016 to September 2021 were collected and analyzed according to their gender, age, underlying diseases, clinical characteristics at admission, laboratory examination results within 24 hours of admission and epidemiological history. The patients were divided into the severe group and the non-severe group according to the diagnostic criteria. The data of clinical characteristics, laboratory examination and prognosis of the two groups were compared. Multivariate logistic regression analysis was performed on the variables with statistical significance and the receiver operating characteristic curve (ROC) was drawn. Results A total of 178 patients were included in this study, with 37 in the severe group and 141 in the non-severe group. Compared with the non-severe group, the age of the severe group was older, the underlying diseases were more, the incidence of dyspnea and the levels of white blood cell, total bilirubin, aspartate aminotransferase, lactate dehydrogenase, cystatin C, uric acid and serum creatinine were significantly increased, the levels of platelet and albumin were significantly decreased (all P<0.05). The dyspnea [odds ratio (OR value)=8.93, 95% confidence interval (CI): 1.200-66.424; P=0.032], total bilirubin (OR=1.091, 95%CI: 1.028-1.159; P=0.004) and serum creatinine (OR=1.052, 95%CI: 1.004-1.102; P=0.033) were independent risk factors for severe tsutsugamushi disease. The area under ROC curve of total bilirubin and serum creatinine were 0.777 and 0.764, respectively (both P<0.01), indicating high predictive value for severe tsutsugamushi disease. The optimal cut-off value for total bilirubin was 23.01 µmol/L, with a sensitivity of 54.10% and a specificity of 90.60%; the optimal cut-off value for creatinine was 126.45 µmol/L, with a sensitivity of 43.20% and a specificity of 100.00%. The case fatality rate of severe tsutsugamushi disease was 2.70%. Conclusions The patients with severe tsutsugamushi disease are older, and have more underlying diseases. Dyspnea, increased total bilirubin and elevated serum creatinine are independent risk factors for severe tsutsugamushi disease, which can help in the early identification of severe tsutsugamushi disease early.

Objective : To investigate the histological damage recovery of temporomandibular joint condylar cartilage caused by chronic unpredictable moderate stress, aiming to provide an experimental basis for the prevention and treatment of temporomandibular disorder. Methods : This animal experiment was approved by the Laboratory Animal Ethical Inspection, School of Stomatology, The Fourth Military Medical University (No. 2020081). 60 male SD rats were randomly divided into control group, stress group, and 2-, 4- and 8-week post-stress recovery groups. Rats were subjected to chronic unpredictable moderate stress (CUMS) for 8 weeks including damp sawdust for 24 hours, tilted cage for 12 hours, noise for 4 hours, light/dark cycle reversal, water immersion, tail clamp, and restraint stress. The serum assessment, behavioral tests, histological and ultrastructural observation were performed 2-, 4- and 8-weeks after stress factors were removed. Serum levels of adrenocorticotropic hormone (ACTH) and corticosterone (CORT) were determined with ELISA. The sucrose preference test (SPT) and the forced swim test (FST) were used to assess the depressive-like behavior. The expression level of interleukin-1α (IL-1α) and matrix metalloproteinases-3 (MMP-3) were determined by Immunohistochemistry and Western blot. Results : At the end of 8 weeks of CUMS, the serum levels of CORT and ACTH were significantly higher in stress group compared with control group (P<0.01). The sucrose preference decreased significantly and the immobility time increased significantly in the stressed rats compared with those in the control group, indicating a successful establishment of CUMS. The condylar cartilage showed significant degenerative changes, with disorganized collagen fibers and reduced proteoglycan synthesis on the cartilage surface. IL-1α and MMP-3 were expressed in the intracellular and extracellular matrix of the condylar cartilage, and their expression levels were increased (P<0.01). After 2 weeks of stress removal, the serum levels of CORT and ACTH were decreased but higher than control group (P<0.01), and behavioral changes were still different from the control group (P<0.01); the loosened collagen fibers could still be seen on the surface of condylar cartilage, and some free cell areas were visible within the proliferative layer; additionally, IL-1α and MMP-3 expression in the condyle was reduced in all layers of cartilage when compared with the stress group, but was still higher than in the control group (P<0.01). After 4 weeks of stress removal, the serum levels of CORT and ACTH changes returned to normal levels and behavioral changes were still different from control group (P<0.05); a few collagen fibers could be seen on the surface of the condylar cartilage and the expressions of IL-1α and MMP-3 decreased significantly compared with the stress group (P<0.01), with the similar level of IL-1α (P>0.05) and higher expression of MMP-3 comparing with the control group (P<0.01). After 8 weeks of stress removal, behavioral changes returned to normal levels, with no statistically significant differences compared with the control group (P>0.05). The condylar collagen fibers increased and showed a corrugated pattern, and no serious subchondral bone damage as well as irreversible damage occurred. Both of the expression levels of IL-1α and MMP-3 approached those of the control group after 8 weeks of stress removal (P>0.05). Conclusion The behavioral changes and condylar cartilage damage caused by CUMS could be self-repaired. The decline in IL-1α and MMP-3 expression may be one of the intrinsic mechanisms of this self-repair process.

Objective:To analyze the epidemiological and clinical characteristics of patients with tsutsugamushi disease in Guangdong Province from 2016 to 2021, and to provide a reference for clinical diagnosis, treatment, scientific prevention and control of tsutsugamushi disease.Methods:A retrospective analysis was conducted to collect the information of patients with tsutsugamushi disease admitted to Guangzhou Eighth Hospital Affiliated to Guangzhou Medical University from 2016 to 2021, including the basic information, epidemiological characteristics, clinical manifestations, auxiliary examinations, complications, misdiagnosis at first diagnosis and treatment outcomes.Results:Among 155 patients with tsutsugamushi disease, there were 75 males (48.39%) and 80 females (51.61%), with an e age of (54.41 ± 13.78) years old, and 30 cases (19.35%) had other underlying diseases. The peak time of onset was from June to September. There were 97 local patients (62.58%) in Guangzhou, and 58 cases (37.42%) in other prefecture-level cities; 76.77% (119/155) had a history of field activities before the onset of the disease. 36.13% (56/155) were farmers. The most common clinical manifestations were fever (100.00%, 155/155), chills and/or shivering (77.42%, 120/155), headache and/or dizziness (74.19%, 115/155), fatigue (65.81%, 102/155), eschar or ulcer (92.90%, 144/155), and lymphadenopathy (49.68%, 77/155). The laboratory test results mainly showed a decrease in eosinophils (81.94%, 127/155), a decrease in hematocrit (78.71%, 122/155), a decrease in hemoglobin (52.26%, 81/155), a decrease in platelet count (50.97%, 79/155), a decrease in albumin (92.26%, 143/155), an increase in lactate dehydrogenase (90.32%, 140/155), an increase in adenosine deaminase (88.39%, 137/155), and an increase in alanine aminotransferase (85.16%, 132/155), elevated aspartate aminotransferase (85.16%, 132/155), and elevated procalcitonin (52.90%, 82/155); 30 cases (19.35%) were positive for the Weil-Felix Test. There were 95 cases (61.29%) with abnormal chest imaging results, and 34 cases (21.94%) with abnormal abdominal ultrasound or CT results. Common complications were toxic hepatitis, pulmonary infection, organ failure, and acute kidney injury, etc. The misdiagnosis rate of the initial diagnosis of this disease was 75.48% (117/155). Doxycycline and symptomatic and supportive therapy were given, 154 patients (99.35%) were cured or improved and discharged from hospital.Conclusions:Tsutsugamushi disease is prevalent in summer and autumn in Guangdong Province. Before the onset, most of the patients have a history of field activities. Farmers are susceptible people. Its clinical manifestations are diverse, and can affect multiple systems and organs. There are many complications, and doxycycline can be used for anti-infection treatment, with a high cure rate.

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 trend of postoperative cavity status in patients with eosinophilic chronic sinusitis with nasal polyps (eCRSwNP) who underwent total nasalization surgery and partial reboot surgery. And to discuss the relationship between tissue eosinophil counts and status of postoperative cavity.Methods:Patients with eCRSwNP in four tertiary medical centers (Longgang ENT Hospital, Xiamen Humanity Hospital, Guangdong Clifford Hospital and the First Affiliated Hospital of Sun Yat-Sen University) from March 2018 to October 2021 were divided into 2 groups. The group without previous surgery history was performed for the nasalization surgery, and another group with previous surgery history underwent the part-reboot surgery. The follow-up time after operation was defined as the following 5 stages: 6, 12, 20-24, 36 and more than 42 months. According to FESS-95 Guangzhou standard, status of sinus cavity was assessed and classified into 3 categories: good, better and bad. The association between the sinus cavity status and tissue eosinophil counts in the above 5 stages was analyzed by one-way ANOVA, and P<0.05 was considered statistically significant. Results:A total of 72 eCRSwNP patients finished the follow-up in this study. There were 47 males and 25 females in these patients, aged from 11 to 67 years. A total of 50 cases underwent nasalization surgery and 22 cases underwent partial reboot surgery. With the follow-up time from 6 to 48 months, there were 72 cases (100.0%) who completed 6 months and 12 months follow up, 46 cases (63.9%) for 20-24 months, 36 cases (50.0%) for 32-36 months and 16 cases (22.2%) with the follow-up time more than 42 months. No matter what kind of surgery, there was no "bad" situation of the surgical cavity status 6 months after the operation, and the differentiation gradually occurred more than 12 months after the surgery. Moreover, the rates of "good" cavity status for the 5 stages in the group of nasalization surgery were 78.0%, 66.0%, 56.7%, 47.6% and 42.9%, and were 63.6%, 45.5%, 25.0%, 20.0% and 11.1% in the partial reboot surgery group, respectively, suggesting that the status of nasal cavity in nasalization surgery group was always better than that in partial reboot surgery group in every period. In addition, the "bad" rate was 0, 8.0%, 10.0%, 14.3% and 28.6% in the group of nasalization surgery, and was 0, 27.3%, 18.8%, 33.3% and 55.6% in the partial reboot surgery group, respectively. The average percentage of tissue eosinophil counts in the 72 cases was 42.1%, which had no obvious effect on the status of the surgical cavity ( P>0.05). Conclusions:For eCRSwNP patients, the operative cavity status in the patients without previous operation history treated with nasalization surgery is good. The time of 1-2 years after surgery is the main period for sinus lesions. The counts of tissue eosinophils has no significant influence on surgical sinus cavity status in the eCRSwNP patients.
