ObjectiveTo picture the trajectory of changes in glucose and lipid metabolism among schizophrenic patients in long-term hospitalization. MethodsA total of 109 inpatients of Shenzhen Kangning Hospital from 2014 to 2022， who were diagnosed with schizophrenia based on the International Classification of Diseases， tenth edition （ICD-10） criteria， were recruited as subjects. Real-world follow-up data on longitudinal glucose metabolism （fasting blood glucose， glycosylated hemoglobin， C-peptide） and lipid metabolism （triglycerides， low density lipoprotein， high density lipoprotein， total cholesterol） were observed. The frequency of visit was once a year， with a total of 9 visits over 8 years. ResultsIn terms of glucose metabolism parameters， fasting blood glucose level decreased to 4.87 mmol/L at the 7^th visit， lower than the baseline level （P<0.01）. Glycated hemoglobin level was 6.08% at the 9^th visit， higher than the baseline level （P<0.05）. C-peptide level was 3.14 ng/mL at the 7^th visit， higher than the baseline level （P<0.01）. As for the trajectory of lipid metabolism parameters， high-density lipoprotein level were significantly lower than baseline level at the second visit （P<0.01） and stayed basically stable thereafter. Total cholesterol levels at the last three visits were 4.06， 4.07 and 3.95 mmol/L， respectively， all lower than the baseline level （P<0.01）. ConclusionThe changes of glycolipid metabolism parameters in long-term inpatients with schizophrenia were generally smooth during the 8-year follow-up period.

Mitochondrial DNA (mt-DNA) is an important carrier of extranuclear genetic information. Recent research results show that mt-DNA is closely related to the occurrence and metastasis of various malignant tumors, and can be used for early diagnosis and targeted therapy of cancer. Therefore, further research on the mechanism of mt-DNA in digestive system malignant tumors has important clinical significance for screening and identifying tumor molecular markers for anti-tumor drug targets, cancer diagnosis and prognosis analysis. This article reviews the research progress on the potential relationship, clinical application and therapeutic targets of mt-DNA and digestive system malignancies.

Purpose: This study aimed to develop a nomogram for predicting pathologic complete response (pCR) after neoadjuvant chemoradiotherapy (CRT) in patients with esophageal squamous cell carcinoma (ESCC) by integrating hematological biomarkers and clinicopathological characteristics. Materials and Methods: Between 2003 and 2017, 306 ESCC patients who underwent neoadjuvant CRT followed by esophagectomy were analyzed. Besides clinicopathological factors, hematological parameters before, during, and after CRT were collected. Univariate and multivariate logistic regression analyses were performed to identify predictive factors for pCR. A nomogram model was built and internally validated. Results: Absolute lymphocyte count (ALC), lymphocyte to monocyte ratio, albumin, hemoglobin, white blood cell, neutrophil, and platelet count generally declined, whereas neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) increased significantly following neoadjuvant CRT. After surgery, 124 patients (40.5%) achieved a pCR. The pCR group demonstrated significantly more favorable survival than the non-pCR group. On multivariate analysis, significant factors associated with pCR included sex, chemotherapy regimen, post-CRT endoscopic finding, pre-CRT NLR, ALC nadir during CRT, and post-CRT PLR, which were incorporated into the prediction model. The nomogram indicated good accuracy in predicting pCR, with a C-index of 0.75 (95% confidence interval, 0.71 to 0.78). Conclusion Female, chemotherapy regimen of cisplatin/vinorelbine, negative post-CRT endoscopic finding, pre-CRT NLR (≤ 2.1), ALC nadir during CRT (> 0.35 ×109/L), and post-CRT PLR (≤ 83.0) were significantly associated with pCR in ESCC patients treated with neoadjuvant CRT. A nomogram incorporating hematological biomarkers to predict pCR was developed and internally validated, showing good predictive performance.

Objective:To explore the application value of conventional ultrasound(US) in detecting occult bleeding lesions in joints of patients with hemophilia.Methods:Twenty-seven children with severe hemophilia A who received factor Ⅷ prophylactic treatment from March 2017 to April 2018 in Nanfang Hospital, Southern Medical University were enrolled. Clinical data were collected from routine practice accompanied with US examination, hemophilia joint health score (HJHS) 2.1 assessment and the history of hemarthrosis of both ankles, elbows and knees at baseline and at 1 year follow-up.Results:A total of 157 joints of 27 patients were followed up for one year. During the treatments, 74 joints were found without history of hemarthrosis, among which the total US score of 14(14/74, 18.9%) joints increased, and HJHS 2.1 score of 11(11/74, 14.9%) joints developed. There was no significant change in the HJHS 2.1 score of 108 joints, among which 25 joints (25/108, 23.1%) had an increase in the total US score.However, there was no significant change in the total US score for 93 joints, of which 9(9/93, 9.7%) had an increase in HJHS 2.1 score.Conclusions:US examination can sensitively detect hemophilia arthropathy in joints without history of hemarthrosis and without obvious progression of arthropathy by HJHS 2.1 examination, and provide clinicians with more accurate joint information.

Objective:To evaluate the accuracy of two-dimensional ultrasound(2D-US), three-dimensional volume ultrasound (3D-US) and ultrasound strain elastography (USE) in the measurement of preoperative tumor size of breast cancer and its influencing factors.Methods:A total of 101 patients with breast cancer in Nanfang Hospital of Southern Medical University from April to November 2016 were recruited in this study. The maximum diameter of the lesion was examined by 2D-US 3D-US and USE before core needle biopsy or surgery biopsy. The Bland-Altman analysis and intraclass correlation coefficient (ICC) were used to analyze the consistency between the ultrasonic technique measurements and the pathological measurements of postoperative lesion. Chi-square test or Fisher exact test was used to analyze whether the accuracy of three imaging techniques was affected by different clinical pathologic factors and imaging characteristics.Results:3D-US showed better agreement with histology than 2D-US and USE, with a higher ICC (ICC 3D-US=0.90>ICC 2D-US=0.81>ICC SUE=0.78) and low variation. In 3D-US, the accuracy rate of the age >40 years old group was higher than ≤40 years old group. In 2D-US, the measurement accuracy of invasive ductal carcinoma (IDC) without intraductal carcinoma in situ (DCIS) group was higher than DCIS with DCIS group, non-microcalcifications group was more accurate than microcalcifications group. The long diameter of lesion ≤2 cm group was more accurate than >2 cm group, IDC group was more accurate than invasive lobular carcinoma(ILC) group. In USE, the measurement accuracy of IDC without DCIS group was higher than DCIS with DCIS group, non-microcalcifications group was more accurate than microcalcifications group. All the differences mentioned above were statistically significant(all P<0.05). Conclusions:For accurate measurement of the size of breast cancer lesions, 3D-US is the best, which is least affected by clinicopathological factors and imaging features, followed by 2D-US and USE. This has certain significance for clinically determining the extent of breast cancer lesions.

Objective:To explore the effect of match between childhood stress and adulthood stress on mental health status.Methods:Adult healthy volunteers( n=239) and adult mental disorder patients were examined by questionnaires or telephone interviews.Childhood trauma questionnaire (CTQ) and lifetime stress event list were used for measure of CS and AS, DSM5-level-1-cross-cutting-symptom-measure (DSM5-L1CCSM) and self-rating depression scale (SDS) for mental health outcomes.Subjects were grouped according to positive (+ ) / negative (-) stress events into five groups: CS+ AS+ Matched ( n=108), CS+ AS+ mismatched( n=240), CS-AS+ ( n=100), CS+ AS-( n=79), and CS-AS-( n=99). The data of stress and mental health status were compared and analyzed among stress groups. Results:The distributions of positive stress events among 626 volunteers were 68.2% with CS+ , 71.6% with AS+ , 17.3% with C+ A+ M+ .There were differences among groups in all parameters (all P<0.05) except for gender.Age, years of education, CS and emotional abuse were influencing factors of onset of AS( P<0.01). MANCOVA analysis showed that factors about the interaction of AS and CS had attribution on DSM5-L1CCSM and SDS ( P<0.01). Conclusion:CS has a facilitatory effect on AS.The match of CS-AS is an important risk factor of adulthood mental health outcomes.Re-experiencing the same type of CS in adulthood would worsen adulthood mental health status.

In December 2018, a 29-year-old female patient with lingual artery embolism after hyaluronic acid injection was admitted to the Second Affiliated Hospital of Kunming Medical College. The examination showed swelling tongue, the mucosa on the front and back of the right tongue became white, and the tip of the tongue slightly atrophied. The movement of tongue was disturbed. The patient′s pronunciation was unclear. The right tongue was numb, resulted by the weak circulation. Hyaluronidase was injected into tongue. The vasodilator was used. And hyperbaric oxygen chamber was applied. Thereafter, the blood supply and oxygen concentration of embolized area were increased, and collateral circulation was established. Antibiotic therapy and continuous treatment with neurotrophic drugs (rat nerve growth factor + methylcobalt ammonium) were given to promote the repair of nerve. After treatment, the embolism of lingual artery was significantly improved. Three months later, the patients had mild muscular atrophy on the right side of the tongue, with partial recovery of the right tongue mucosa. Tongue movement, sensory and taste functions recovered. Hyaluronic acid injection needs to be standardized, performed by surgeons who masters the anatomical structures, the injection layer and spot. If the vascular embolism occurs, hyaluronidase should be used as early as possible. It also needs to reduce local tension in both injected and affected area, reduce the pressure of injection on blood vessels, improve local blood circulation, so as to achieve better therapeutic effect.

OBJECTIVE: To investigate the effect of osthole on the expression of amyloid precursor protein (APP) in Alzheimer's disease (AD) cell model and its mechanism. METHODS: The SH-SY5Y cell with over expression of APP was established by transfection by liposome 2000. The cells were treated with different concentrations of osthole, and the cell viability was determined by MTT and lactate dehydrogenase (LDH) assay. The differentially expressed miRNAs with and without osthole treatment were detected by miRNA array, and the target genes binding to the differentially expressed miRNAs were identified and verified by databases and Cytoscape. After the inhibitor of the differentially expressed miRNA was transduced into cells, the changes of APP and amyloid β (Aβ) protein were determined by immunofluorescence cytochemistry, and the mRNA expression of APP was determined by RT-PCR. RESULTS: The AD cell model with over expression of APP was established successfully. The results of MTT and LDH assay showed that osthole had a protective effect on cells and alleviated cell damage. miR-101a-3p was identified as the differentially expressed miRNA, which was binding to the 3'-UTR of APP. Compared with APP group, the expression of APP and Aβ protein and APP mRNA increased in the miR-101a-3p inhibitor group (all <0.01), while the expression of APP and Aβ protein and APP mRNA decreased in the cells with osthole treatment (all <0.01). CONCLUSIONS Osthole inhibits the expression of APP by up-regulating miR-101a-3p in AD cell model.

Objective To explore the effect of childhood trauma on escitalopram treatment of adult depression. Methods There were 68 adult patients with major depression disorder recruited. All patients were assessed with Childhood Trauma Questionnaire ( CTQ ) and given 8 weeks of standardized treatment with escitalopram. Beck Depression Inventory ( BDI) and HAMD-17 were assessed at the end of the 2nd,4th and 8th week respectively. The changes of BDI score and HAMD-17 score in patients with different CTQ fac-tors were observed. Results ( 1) The overall effect of intervention was 25. 0％ at the end of 4th week and 45. 6％ at the end of 8th week. The total effective rate was 94. 1％. At the end of 4th week,there was no sig-nificant difference in the clinical recovery rate between the positive group(19. 5％) and the negative group (33. 3％)(χ2=1. 66,P>0. 05). There was no significant difference in clinical recovery between the two groups at the end of 8th week(positive group :39. 0％,negative group :55. 6％,χ2=1. 79,P>0. 05). (2) The total score reduction rate of HAMD-17((46. 26±24. 79)％,(58. 39±23. 25)％) and BDI((51. 63± 16. 03)％,(66. 28±18. 05)％) at the end of 4th week and the total score reduction rate of BDI at the end of 8th week ((59. 13±15. 42)％,(68. 50±20. 91)％)in the positive group were lower than those in the nega-tive group (P<0. 05) . ( 3) Except for sexual abuse,there was a significant negative correlation between CTQ scores and the reduction rate of BDI scores at end of 4th and 8th week( r=-0. 46--0. 06,P<0. 05) . Conclu-sion Childhood trauma has adverse effects on the efficacy of escitalopram in the treatment of adult depres-sion.
