This technique significantly enhances the efficacy and safety of minimally invasive surgery for anterior mediastinal masses, reduces trauma and postoperative pain, and accelerates patient recovery, demonstrating important clinical significance and application value.

ObjectiveTo investigate the status of liver function abnormalities in patients with severe mental disorder (SMD) in Shanghai community, to explore the related factors to abnormal liver function in patients with SMD, and to analyze the effects of the types of mental disorders and medication status on liver function abnormalities. MethodsThe patients with SMD in Jinshan District, Minhang District, Hongkou District and Xuhui District of Shanghai were selected as the research subjects. Questionnaire survey, physical examination and laboratory tests were conducted to obtain their demographic characteristics and liver function indicators such as alanine aminotransferase (ALT) and total bilirubin (TBil). The types of mental disorders and medication status of patients in Jinshan District were also investigated. Abnormalities in liver function were determined by abnormalities in either ALT or TBil. Binary logistic regression analysis was used for multivariate analysis of the status of abnormal liver function, and the effects of mental disorder types and medication status on liver function were analyzed, simultaneously. ResultsA total of 7 251 patients with SMD were finally included into this study, and the rate of liver function abnormality was 22.7%, of which 694 cases (9.6%) had ALT abnormality and 1 084 cases (14.9%) had TBil abnormality. Univariate analysis showed that the rate of liver function abnormalities was higher in males than that in females (χ²=45.026, P<0.001), higher in suburbs than that in urban areas (χ²=25.317, P<0.001), higher in those with higher BMI than in those with lower BMI (χ²=63.748, P<0.001), higher in those with elevated blood pressure (BP) than in those without elevated BP (χ²=24.774, P<0.001), higher in those with elevated blood glucose than in those without elevated blood glucose (χ²=43.345, P<0.001), higher in those with abnormal triglyceride (TG) than in those with normal TG (χ²=15.551,P<0.001), and higher in those with abnormal total cholesterol (TC) than in those with normal TC (χ²=10.962, P=0.001). Multivariate analysis showed that the rate of abnormal liver function was higher in males than that in females (OR=1.53, 95%CI: 1.36‒1.73), higher in suburbs than that in urban areas (OR=1.43, 95%CI: 1.21‒1.70), higher in those with overweight than in those with normal BMI (OR=1.16, 95%CI: 1.01‒1.33), higher in those with obesity than in those with those with normal BMI (OR=1.61, 95%CI: 1.36‒1.91), higher in those with elevated blood glucose than in those without elevated blood glucose (OR=1.39, 95%CI: 1.23‒1.58), and higher in those with abnormal TC than in those with normal TC (OR=1.36, 95%CI: 1.13‒1.65).The difference in the rate of ALT abnormalities among the SMD patients in Jinshan District with different medication status was statistically significant (χ²=21.928, P<0.001). Whereas, the differences in the effects of the types of mental disorders and medication status on the status of liver function abnormalities were not statistically significant(P>0.05). ConclusionThe detection rate of liver function abnormalities in community-based SMD patients in Shanghai is high, and male, suburban, and accompanied by elevated BMI, BP, blood glucose, and TC are risk factors for liver function abnormalities in patients with SMD. Primary healthcare providers should pay more attention to the liver function of patients with SMD and initiate targeted and tailored prevention, detection and treatment measures.

To explore screening tools for children with autism spectrum disorder (ASD), which are convenient for primary hospitals, it can provide basic data for formulating ASD prevention policies. This was a cross-sectional study by cluster sampling. Huyi District and Xincheng District were extracted for investigation in Xi′an City. From July 2021 to September 2022, all children aged from 3 months to 36 months who live in the two districts were subjected to primary screening. The child care physician used the routine screening tool "warning signs checklist for screening psychological, behavioral and developmental problems of children" and cartoon pictures of "early high-risk warning signs of autism", the children who were positive in the initial screening were referred to the district level maternal and child health hospital for re-screening, and those who were positive in the re-screening were referred to Xi ′an Children′s Hospital for diagnosis. The results showed that a total of 17 905 children aged from 3 months to 36 months were initially screened in the two districts, including 10 588 children aged from 18 months to 36 months, 50 children who were positive in the initial screening and 50 children who were re-screened. 23 children (18 boys and 5 girls) were diagnosed with ASD. The prevalence rate of ASD in children was 2.17‰ (95% confidence interval:1.29‰-3.06‰). 42 children were positive for "warning signs checklist" at the preliminary screening, and 19 were confirmed as ASD. 27 children were positive for "cartoon pictures" in the preliminary screening, and 23 were confirmed with ASD. The "cartoon pictures" in the preliminary screening and diagnosis of consistent rate was higher than the "warning signs checklist", two kinds of screening methods comparison were statistically significant difference in the odds of consistent (χ 2=11.01, P=0.001). In conclusion, relying on the three-level network of maternal and child health care, it is conducive to the whole process management of screening and diagnosis of children with ASD, and to guide the formulation of prevention policies. The cartoon pictures of "early high-risk warning signs of autism" can assist the identification of children with ASD based on the "warning signs checklist", which is simple, effective and suitable for promotion in the community health care.

Myocardial dysfunction is the most serious complication of sepsis. Sepsis-induced myocardial dysfunction (SMD) is often associated with gastrointestinal dysfunction, but its pathophysiological significance remains unclear. The present study found that patients with SMD had higher plasma gastrin concentrations than those without SMD. In mice, knockdown of the gastrin receptor, cholecystokinin B receptor (Cckbr), aggravated lipopolysaccharide (LPS)-induced cardiac dysfunction and increased inflammation in the heart, whereas the intravenous administration of gastrin ameliorated SMD and cardiac injury. Macrophage infiltration plays a significant role in SMD because depletion of macrophages by the intravenous injection of clodronate liposomes, 48 h prior to LPS administration, alleviated LPS-induced cardiac injury in Cckbr-deficient mice. The intravenous injection of bone marrow macrophages (BMMs) overexpressing Cckbr reduced LPS-induced myocardial dysfunction. Furthermore, gastrin treatment inhibited toll-like receptor 4 (TLR4) expression through the peroxisome proliferator-activated receptor α (PPAR-α) signaling pathway in BMMs. Thus, our findings provide insights into the mechanism of the protective role of gastrin/CCKBR in SMD, which could be used to develop new treatment modalities for SMD.

Objective To investigate the prevalence of hepatitis D virus (HDV) infection among patients with chronic hepatitis B virus (HBV) infection in some regions of China. Methods Serum samples were collected from 3 131 patients with chronic HBV infection in 10 provinces, cities, and autonomous regions of China from March 2021 to June 2022, and anti-HDV IgG ELISA was used for the detection of all serum samples. Nested reverse transcription-polymerase chain reaction (nRT-PCR) was used to detect HDV RNA in anti-HDV IgG-positive samples, and the nRT-PCR amplification products of HDV RNA-positive samples were sequenced and analyzed to determine HDV genotype. The clinical features of anti-HDV IgG-positive patients were analyzed. The Mann-Whitney U rank sum test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups. Results The positive rate of anti-HDV IgG in the 3 131 patients with chronic HBV infection was 0.70% (22/3 131), and that in the patients with chronic HBV infection in Inner Mongolia Autonomous Region, Xinjiang Uygur Autonomous Region, Beijing, and Hunan Province was 1.81% (16/886), 0.88% (2/226), 0.28% (2/708), and 1.00% (2/200), respectively; the patients with chronic HBV infection in Inner Mongolia Autonomous Region had a significantly higher positive rate of anti-HDV IgG than those in Beijing ( P =0.004), and there was no significant difference between the other regions ( P > 0.05). Clinical features of the patients with chronic HBV infection in Inner Mongolia Autonomous Region showed that compared with the anti-HDV IgG-negative group, the anti-HDV IgG-positive group had a significantly higher proportion of patients with Mongol nationality ( P =0.001), abnormal alanine aminotransferase ( P =0.007), or antiviral treatment ( P =0.029), as well as a significantly lower median HBV DNA level ( P =0.030). A total of 19 HDV RNA-positive samples were identified, all of which had HDV genotype 1. Conclusion The prevalence rate of HDV varies greatly across different regions of China, with a higher prevalence rate of HDV in patients with chronic HBV infection from Inner Mongolia Autonomous Region. HDV genotype 1 is the predominant genotype in some provinces and cities of northern China.

ObjectiveTo explore the relapse status based on the positive and negative syndrome scale （PANSS Scale） and related factors of schizophrenics in Shanghai communities， and to analyze the association between socio demographic characteristics， lifestyles， clinical characteristics and relapse. MethodsA dynamic cohort prospective study design was used in this study. From March 2018 to February 2019， a total of 189 schizophrenics in Xuhui， Hongkou， Changning， Jiading， Songjiang and Baoshan districts were enrolled successively. Baseline questionnaires were conducted through face-to-face interviews at baseline， which contained social demographic information， lifestyle information and clinical information. A follow-up was conducted every 2 weeks for a measurement of PANSS Scale for a total of 6 months. Relapse was assessed by a PANSS score increase of ≥25% from baseline （or an increase of 10 points or more if the baseline score was ≤40 points）. Univariate and multivariate Cox regression models were used to analyze the associations between relapse status （assessed by PANSS Scale） and socio demographic characteristics， lifestyles， and clinical characteristics， respectively. ResultsA total of 165 community schizophrenics completed baseline and follow-up surveys， with a loss to follow-up rate of about 12.7%. After exclusion of sociodemographic and clinical information deficits， 132 patients were included in the analysis totally， with an average age of 48.18±12.67 years， among whom 41.67% were male. Totally 33 patients relapsed during the 6-month follow-up period， with a relapse rate of 25.0%. After adjusting for gender， family history， age， employment， education， marital status， smoking， drinking， exercise frequency， medication compliance， insight， social function， violence history， stress recent events， adverse drug reactions and baseline scores of PANSS Scale， risk factors of relapse included the following four factors： age below 40 years （HR=4.47， 95%CI： 1.15-17.40）， primary school or below （HR=7.11， 95%CI： 1.54-32.83）， unemployed （HR=8.34， 95%CI： 1.78-38.98）， and adverse drug reactions （HR=5.02， 95%CI： 1.75-14.37）. ConclusionWe should pay attention to the risk factors such as age， education， employment and adverse drug reactions， in order to identify high-risk patients and to conduct timely interventions during the relapse management of schizophrenics in Shanghai community.

ObjectiveTo explore the effect of paliperidone palmitate treatment on schizophrenic patients in the community. Methods446 schizophrenic patients who used paliperidone palmitate injection were selected in Shanghai. Before and after the treatment， the disease family burden scale， the concise evaluation scale of drug treatment compliance， the VAS100 score of treatment satisfaction， the short form of quality of life measurement scale， and the screening scale of social function defects were used to evaluate the effects of paliperidone palmitate injection. The data were statistically analyzed using SPSS 26.0 software. ResultsAfter using paliperidone palmitate injection， the total score of family burden （13.94±12.17）， the score of daily family activities （3.26±2.74）， the score of family entertainment activities （2.21±2.30）， and the score of family relationship （2.79±2.76） were significantly higher than those before the treatment （14.98±12.64， 3.51±2.88， 2.48±2.38， 3.11±2.87， respectively， all with P<0.05）. The scores of the World Health Organization on quality of life brief scale （62.89±11.94） and the medication compliance scale （28.11±5.64） were better than those before treatment （60.67±12.62 and 27.37±6.96， all with P<0.05）. Compared with the prior treatment without paliperidone palmitate injection， the number of readmissions after treatment was significantly reduced （P<0.01）. ConclusionThe treatment of paliperidone palmitate injection has significant effect， which can effectively reduce the disease family burden of Schizophrenic patients， improve their quality of life， enhance their drug compliance， reduce the readmission rate of patients， ensure long-term treatment effect and promote disease recovery.

OBJECTIVE To isolate and identify the chemical compounds of the n-butanol fraction of the pods of Macleaya microcarpa, and to predict the targets and pathways for its treatment of Alzheimer's disease by network pharmacology. METHODS Silica gel, Sephadex LH-20 column chromatography and ODS preparative liquid chromatography were used to separate and purify the n-butanol extract of the pods of Macleaya microcarpa, and the structure of the compounds were identified by NMR spectroscopic. The targets of active compounds were obtained using SwissTargetPrediction and Targetnet database. Alzheimer's disease-related target were obtained by Genecard, OMIM and TTD database. The two were imported into Venny online tool to select the effect targets of the active compounds for Alzheimer's disease treatment. The interaction network map of “drug-component-target-disease” was constructed by Cytoscape 3.9.1 software. The String database was used to build the protein protein interaction network analysis. KEGG and GO pathway enrichment analysis were performed with Metascape database, and molecular docking was studied with AutoDockTools 1.5.7 software. RESULTS Five phenolic glycosides were isolated from the n-butanol fraction of the pods of Macleaya microcarpa. Ten key targets such as TNF, PTGS2 and APP, and 10 important pathways such as Pathways in cancer, Serotonergic synapse and Alzheimer's disease were screened by network pharmacology, and molecular docking showed that the active ingredients had good binding ability to the key targets. CONCLUSION Compounds 3-5 are isolated from Macleaya microcarpa for the first time, and compound 5 is isolated from Papaveraceae for the first time. The mechanism of Macleaya microcarpa in the treatment Alzheimer's disease may affect on key targets such as TNF, PTGS2, APP, ABCB1, and influence signaling pathway such as the APP/Aβ/NMDAR, so as to reduce inflammatory factors, inhibit inflammatory responses and reduce Aβ deposition in the brain.

Objective:To investigate the clinicopathological features,differential diagnosis,treatment and prognosis of Burkitt-like lymphoma with 11q aberration (BLL-11q).Methods:The clinical manifestations,histological morphology,immunophenotype and molecular genetic changes of 2 cases of BLL-11q admitted to the department of pathology of The First People's Hospital of Lianyungang in 2020 and 2021 were analyzed retrospectively,and the relevant literatures were reviewed.Results:Patients were found with right neck masses inadvertently and grew rapidly. They presented with localized disease with Ann Arbor stages IA and IIA. Microscopically, the normal structure of the lymph node disappeared and was replaced by a diffuse proliferation of lymphocytes, with consistent morphology and medium size. And the presence of "star-sky" phenomenon was obvious, the morphological characteristics were similar to Burkitt lymphoma. Immunophenotypically, tumor cells were diffusely positive for CD20, CD79α, PAX5, CD10 and Bcl-6, partly moderately positive for C-MYC and MUM-1, however, CD3, Bcl-2, CD30 and TDT were negative,Ki-67 positive index was more than 95%, and EBER was negative. FISH detection showed that MYC, Bcl-2, and Bcl-6 were negative. Both cases had the 11q23.3 gain and 11q24.3 loss. Both patients were treated with chemotherapy and followed up for 10-22 months,and achieved complete remission and disease-free survival.Conclusion:BLL-11q is a rare germinal center B-cell lymphoma with abnormal long arm of chromosome 11 and lack of MYC gene rearrangement. It should be distinguished from Burkitt lymphoma, diffuse large B-cell lymphoma, B-lymphoblastic lymphoma, large B-cell lymphoma with IRF4 rearrangement and high-grade B-cell lymphoma. On the basis of morphology and immunophenotype, the diagnosis depends on genetic detection. There may be a better prognosis.
