Background Agitated behaviour in male patients with schizophrenia can lead to serious consequences for the individual and the society.Non-invasive drug delivery may help to rapidly control agitation and improve the overall patient satisfaction,but there are limited studies on the efficacy of olanzapine oral soluble film for the treatment of agitated behaviour in patients with schizophrenia.Objective To compare the efficacy and safety profile of olanzapine oral soluble film versus intramuscular haloperidol against agitated behaviour in male patients with schizophrenia,so as to provide a reference for the treatment of agitated behaviour.Methods From May 2022 to July 2023,a consecutive sample of schizophrenic patients(n=44)with agitated behaviour who met the Diagnostic and Statistical Manual of Mental Disorders,fifth edition(DSM-5)were recruited in the male psychiatric closed ward of the Third People's Hospital of Fuyang.Patients were assigned into two groups using the random number table method,each with 22 cases.Study group was treated with olanzapine oral soluble film 10 mg/d,while control group was given intramuscular haloperidol 8 mg/d.The severity of agitated behaviour was determined using Positive and Negative Syndrome Scale-Excited Component(PANSS-EC)and Agitation Calmness Evaluation Scale(ACES)at the baseline and after 6 h of drug administration.The treatment response rate was calculated based on the reduction of PANSS-EC score,and the drug side effects were assessed using Rating Scale for Extrapyramidal Side Effects(RSESE)and Barnes Akathisia Rating Scale(BARS)after 6 h of drug administration.Results After 6 h of drug administration,no statistical difference was reported in PANSS-EC score and ACES score between two groups(F=0.039,0.082,P>0.05),and the treatment response rate yielded no statistical difference between two groups(χ2=0.419,P=0.517),while study group reported a lower incidence rate of adverse reactions compared with control group,with statistically significant difference(P=0.031).BARS scores noted no statistical significant difference between two groups(t=0.587,P=0.561),whereas study group scored lower on RSES compared to control group,with a statistical difference(t=-7.367,P<0.01).Conclusion In the treatment of agitation in male patients with schizophrenia,the efficacy of olanzapine oral soluble film is comparable to that of intramuscular haloperidol,while the safety profile of the former is superior to that of the latter.

Nonalcoholic steatohepatitis (NASH) is a spectrum of chronic liver disease characterized by hepatic lipid metabolism disorder. Recent reports emphasized the contribution of triglyceride and diglyceride accumulation to NASH, while the other lipids associated with the NASH pathogenesis remained unexplored. The specific purpose of our study was to explore a novel pathogenesis and treatment strategy of NASH via profiling the metabolic characteristics of lipids. Herein, multi-omics techniques based on LC-Q-TOF/MS, LC-MS/MS and MS imaging were developed and used to screen the action targets related to NASH progress and treatment. A methionine and choline deficient (MCD) diet-induced mouse model of NASH was then constructed, and Schisandra lignans extract (SLE) was applied to alleviate hepatic damage by regulating the lipid metabolism-related enzymes CES2A and CYP4A14. Hepatic lipidomics indicated that MCD-diet led to aberrant accumulation of phosphatidylethanolamines (PEs), and SLE could significantly reduce the accumulation of intrahepatic PEs. Notably, exogenous PE (18:0/18:1) was proved to significantly aggravate the mitochondrial damage and hepatocyte apoptosis. Supplementing PE (18:0/18:1) also deteriorated the NASH progress by up regulating intrahepatic proinflammatory and fibrotic factors, while PE synthase inhibitor exerted a prominent hepatoprotective role. The current work provides new insights into the relationship between PE metabolism and the pathogenesis of NASH.

ObjectiveTo construct an evaluation index system for the development of district-level disease prevention and control centers according to the requirements of the modernization of Shanghai’s disease control system and public health work practices， and to comprehensively assess the construction and development of district-level disease prevention and control institutions. MethodsAccording to the national and municipal requirements for the development of disease prevention and control institutions， an index framework was proposed through literature search and expert interviews. 39 representative experts in the field of public health at the national， provincial， and municipal （district） levels were selected to participate in the consultation and construction of the index system. The authority coefficient， the coefficient of variation， etc. were used to carry out quality control and determination of each index on the Delphi method. ResultsThe questionnaire response rate was 100%， the expert authority coefficient was 0.86，the degree of familiarity was 0.79， and the judgment basis was 0.92. The coefficients of variation of the necessary indicators in the index system were all <0.25 in the dimension of importance， and there were statistical differences in the statistical test of Kendall’s W coordination coefficients at all levels and dimensions （all P<0.001）. After multiple rounds of consultation， experts reached a consensus， forming a development evaluation index system of district-level CDCs with 6 first-level indicators， 24 second-level indicators， and 105 third-level indicators （including 63 necessary indicators and 42 recommended indicators）. ConclusionThe evaluation index system of Shanghai district-level CDCs based on the Delphi method has good authority， reliability， sensitivity and operability. This indicator system can effectively support the development of Shanghai district-level CDCs， and can be used for evaluation at multiple levels and in an all-round way in the future. The evaluation results can provide an evidence-based basis for the modernization of the disease prevention and control system and the continuous and dynamic updating of the development goals in the future.

Objective:To investigate the effectiveness of a hierarchical teaching model guided by "residency-specialty integration" in residency training and specialty training of oral and maxillofacial surgery with the training base of oral and maxillofacial surgery in Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, as the research subject.Methods:A total of 144 trainees receiving residency training and 32 receiving specialist training were enrolled from June 2022 to April 2023 and were divided into experimental group and control group, with 72 trainees receiving residency training and 16 receiving specialist training in each group. Clinical and learning tasks were designed using the traditional model for the control group and the hierarchical teaching model guided by "residency-specialty integration" for the experimental group, and the performance of trainees in theoretical assessments and self-evaluations was recorded. SPSS 23.0 was used to perform the t-test. Results:The hierarchical teaching model guided by "residency-specialty integration" achieved a significant effect in both theoretical assessments and self-evaluations of the trainees. As for the trainees receiving specialty training, there was a significant difference in the score of theoretical assessment between the experimental group and the control group (84.56±4.05 vs. 81.13±2.78, P<0.05), and as for the trainees receiving residency training, there was also a significant difference in this score between the experimental group and the control group (84.74±4.85 vs. 82.10±4.34, P<0.01). The results of self-assessment questionnaire showed that compared with the control group, the experimental group had a higher proportion of trainees giving positive evaluations of various indicators. Conclusions:This study suggests that the hierarchical teaching model guided by "residency-specialty integration" provides an effective teaching model for residency training and specialty training of oral and maxillofacial surgery, and this model may help to enhance disciplinary interests and promote clinical practice abilities, thereby providing valuable insights for future medical education in China.

Objective:Hepatocellular carcinoma (HCC) is the fourth most dominant cancer in the world and the second leading cause of cancer-related deaths in the China. With the increase in the incidence of metabolic syndrome (MS) in the population, the correlation between MS and HCC has gradually been recognized. MS manifests as non-alcoholic fatty liver disease (shortly known as NAFLD) in the liver. A large number of research results has shown that the development of fatty liver is closely related to the occurrence of HCC, in which lipid metabolism plays a key regulatory role, and lipid metabolism is regulated by fatty acid binding protein (FABP). This study signifies the lipid metabolism analysis and the key FABP expression conditions in HCC.Methods:Data of patients who were first diagnosed with primary HCC between January 2016 to July 2019 were collected, and were divided into two groups according to the etiology, namely the viral and non-viral hepatitis-related HCC group. The relationship between MS-related factors and HCC was analyzed by t-test and chi square test. The expressions of FABP1, FABP4 and FABP5 were detected in cancer and adjacent tissues by immunohistochemistry, and the expressions of FABP1, FABP4 and FABP5 in HCC with fatty liver were detected by immunofluorescence. Finally, the expressional characteristics of the above-mentioned FABPs in HCC patients were analyzed with different clinicopathological features.Results:There were statistically significant differences in the rate of abnormal lipid metabolism and the number of abnormalities in MS-related factors between the viral and non-viral hepatitis-related HCC group. FABP1, FABP4, and FABP5 expression in HCC tissues were lower than the corresponding adjacent tumor tissues. Compared with simple HCC, FABP1, FABP4, FABP5 expression were increased in HCC tissues with steatosis, and the expression of FABP was closely related to the clinical characteristics of patients.Conclusion:Abnormal lipid metabolism is closely related to non-viral hepatitis-related HCC. The expression of lipid metabolism regulatory proteins FABP1, FABP4, and FABP5 are down-regulated in HCC tissues, but up-regulated in HCC with fatty liver, suggesting that the relationship between MS, especially dyslipidemia, and HCC should be paid attention to in clinical practice for early intervention. FABP1, FABP4, FABP5 may regulate HCC occurrence and development.

Objective To identify a clinical isolate of Mycobacterium abscessus.Methods A pus sample was collected from a patient with suspected nontuberculous mycobacterial infection who visited the Affiliated Hospital of Weifang Medical University on December 18,2017,and was subjected to bacterial culture,Gram staining and acid-fast staining.Drug sensitivity test was conducted by the proportion method.The genome DNA of the strain was extracted and amplified by PCR with the universal primer of 16S rRNA.The PCR products were sequenced after collection and purification,and were compared with the known sequence of Mycobacterium abscessus in GenBank database.The isolate was identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS).Results The clinical isolate was identified as Mycobacterium abscessus both by MALDI-TOF MS and 16S rRNA gene sequencing.The drug sensitivity test showed that the strain was sensitive to amikacin,moxifloxacin,levofloxacin,but was resistant to streptomycin,isoniazid,rifampicin,ethambutol,ofloxacin,kanamycin,capreomycin,aminosalicylic acid,protionamide and rifabutin.The patient was diagnosed with subcutaneous soft tissue infection in the left knee joint.According to the results of drug sensitivity test,the patient was treated with amikacin and levofloxacin,and her condition was improved after treatment.Conclusion The 16S rRNA gene detection and MALDI-TOF MS both can be applied in the identification of Mycobacterium abscessus.

OBJECTIVE:To systematically review the effect of organic cation transporter 2 [(OCT2)808G>T] gene polymor-phism on the metformin hydrochloride pharmacokinetics in vivo,and to provide evidence-based reference for clinical medication. METHODS:Retrieved from PubMed,EMBase,Foreign Medical Journey Service,CJFD,VIP database and Wanfang database,re-lated studies about the effect of (OCT2)808G>T gene polymorphism on the metformin hydrochloride pharmacokinetics in vivo were collected,and Meta-analysis was performed by using Rev Man 5.1 statistics software. RESULTS:A total of 5 retrospective studies were included,involving 172 patients. The result of gene type was type GT,type TT and type GG. Results of Meta-analysis showed,compared with type GT volunteers,type TT could prolong the half-time period of metformin hydrochloride;compared with type TT,type GG could increase the peak concentration. However,(OCT2)808G>T gene polymorphism had no effects on the renal clearance rate,creatinine clearance rate and area under the drug-time curve. CONCLUSIONS:(OCT2)808G>T gene poly-morphism has certain effect on the half-time period and peak concentration of metformin hydrochloride in vivo of health volunteer, and has no effect on the renal clearance rate,creatinine clearance rate and area under the drug-time curve. Due to the limit of re-search methodological quality,large-scale and high quality studies are required for further validation of the conclusions.
