ObjectiveTo investigate the anti-Alzheimer's disease (AD) effect of Dipsacus asper(DA) in the Caenorhabditis elegans model, and decipher the underlying mechanism via the peroxisome proliferator-activated receptor α (PPARα)/transcription factor EB (TFEB) pathway. MethodsFirst, transgenic AD C. elegans individuals were assigned into the blank control, model, positive control (WY14643, 20 µmol·L-1), and low-, medium-, and high-dose (100, 200, and 400 mg·L-1, respectively) DA groups. The amyloid β-42 (Aβ42) formation in the muscle cells, the paralysis time, and the deposition of amyloid β-protein (Aβ) in the head were detected. The lysosomal autophagy in the BV2 cell model was examined by Rluc-LC3wt/G120A. The expression levels of lysosomal autophagy-related proteins LC3Ⅱ, LC3I, LAMP2, and TFEB were detected by Western blot. Real-time quantitative polymerase chain reaction (Real-time PCR) was employed to determine the mRNA levels of autophagy-related genes beclin1 and Atg5 and lysosome-related genes LAMP2 and CLN2 downstream of PPARα/TFEB. A reporter gene assay was used to detect the transcriptional activities of PPARα and TFEB. Immunofluorescence was used to detect the fluorescence intensity of PPARα, and the active components of the ethanol extract of DA were identified by UPLC-MS. RCSB PDB, Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), and Autodock were used to analyze the binding between the active components and PPARα-ligand-binding domain (LBD). ResultsCompared with the model group, the positive control group and 200 and 400 mg·L-1 DA groups showed prolonged paralysis time (P<0.05), and all the treatment groups showed decreased Aβ deposition in the head (P<0.01). DA within the concentration range of 50-500 mg·L-1 did not affect the viability of BV2 cells. In addition, DA enhanced the autophagy flux (P<0.05), up-regulated the mRNA levels of beclin1, Atg5, LAMP2, and CLN2 (P<0.05, P<0.01), promoted the nuclear translocation of TFEB (P<0.05), increased LAMP2 expression and autophagy flux (P<0.05, P<0.01), and enhanced the transcriptional activities of PPARα and TFEB (P<0.01). The positive control group and 200 and 400 mg·L-1 DA groups showed enhanced fluorescence intensity of PPARα in the BV2 nucleus (P<0.01). UPLC-MS detected nine known compounds of DA, from which 8 active components of DA were screened out. The docking results suggested that a variety of components in DA could bind to PPARα-LBD and form stable hydrogen bonds. ConclusionDA may reduce the pathological changes in AD by regulating the PPARα-TFEB pathway.

[Objective] To study the molecular biological mechanism for a case of ABO blood group B subtype, and perform three-dimensional modeling of the mutant enzyme. [Methods] The ABO phenotype was identified by the tube method and microcolumn gel method; the ABO gene of the proband was detected by sequence-specific primer polymerase chain reaction (PCR-SSP), and the exon 6 and 7 of the ABO gene were sequenced and analyzed. Homologous modeling of Bw.03 glycosyltransferase (GT) was carried out by Modeller and analyzed by PyMOL2.5.0 software. [Results] The weakening B antigen was detected in the proband sample by forward typing, and anti-B antibody was detected by reverse typing. PCR-SSP detection showed B, O gene, and the sequencing results showed c.721 C>T mutation in exon 7 of the B gene, resulting in p. Arg 241 Trp. Compared with the wild type, the structure of Bw.03GT was partially changed, and the intermolecular force analysis showed that the original three hydrogen bonds at 241 position disappeared. [Conclusion] Blood group molecular biology examination is helpful for the accurate identification of ambiguous blood group. Homologous modeling more intuitively shows the key site for the weakening of Bw.03 GT activity. The intermolecular force analysis can explain the root cause of enzyme activity weakening.

[Objective] To retrospectively analyze the detection results of alanine aminotransferase (ALT) unqualified repeat blood donors in Guangzhou, so as to provide evidence for further expanding the repeat blood donor pool, reducing the rate of blood discarding and improving the qualified rate of blood test. [Methods] Blood donors with unqualified ALT in Guangzhou Blood Center from January 2018 to April 2024 were selected as the research objects. The past blood donation and population characteristics were analyzed according to the number of blood donations and ALT unqualified times. [Results] Among repeat blood donors with previous ALT disqualification, 99.5% to 99.7% did not have reactive markers for transfusion-transmitted diseases (TTD), which was higher than the rate among first-time blood donors with unqualified ALT (95.8%) (P<0.05). The rate of single-item ALT disqualification in repeat blood donors was higher in males than in females (P<0.05); it also varied by age (18-25 years > 26-35 years > 36-45 years > over 45 years) (P<0.05); and by quarter (third and fourth quarters > first and second quarters) (P<0.05). The ALT unqualified rate was significantly higher whole blood donors than that of platelet donors and returning blood donors (P<0.05). The overall ALT level (51.0 U/L), individual ALT level (56.0 U/L) and individual ALT unqualified rate (66.7%) of repeat blood donors with multiple ALT disqualifications were higher than those of repeat blood donors with single-item ALT disqualifications (26.0 U/L, 38.5 U/L, and 33.3%, respectively) (P<0.05). Moreover, as the number of ALT disqualifications increased, the overall level of ALT in repeat blood donors also increased (P<0.05), and the average level of individual ALT and individual ALT unqualified ratio tended to increase. Repeat blood donors with frequent ALT disqualifications had higher ALT levels (69.0 U/L). [Conclusion] The ALT unqualified rates of repeat blood donors were mostly non-specific elevation without TTD. Repeat blood donors with multiple ALT disqualifications tend to have continuous high ALT. Moreover, and with the increase of ALT disqualifications times, the overall ALT levels the average individual ALT levels and individual ALT unqualified rates showed an increasing trend.

ObjectiveTo investigate the current status of emergency management for severe mental disorders in Shanghai, and to provide countermeasures and suggestions for the establishment of a sound emergency management system for severe mental disorders and the enhancement of emergency management capability. MethodsA questionnaire survey and qualitative interviews were used to conduct an investigation into the emergency management in 17 district-level mental illness prevention and control institutions in Shanghai, which includes the basic situation of emergency management for severe mental disorders, the construction of emergency response teams and personnel, emergency preparedness drills and training, emergency management plans and rules and regulations, and problems encountered in emergency management. ResultsIn terms of emergency management mechanism and basic situation, resources such as personnel allocation, security funds and green channel were well equipped in each district-level mental illness prevention and control institution in Shanghai. However, the equipment of some hardware facilities was still insufficient to some extent. Therefore, further improvement on the emergency management mechanism for severe mental disorders was needed. With regard to the construction of emergency team and personnel allocation, the majority were those aged between 35‒<45 years old, with a bachelor’s degree, and more than 10 years of working experience. For example, 90.27% staff in district-level mental illness prevention and control institution had a bachelor’s degree or above, which was higher than that among the staff in community-level (73.60%); staff majored in clinical medicine in district-level institution accounted for the proportion at 52.71%, higher than that among the staff in community-level (28.86%); 57.24% staff in district-level institution had an intermediate professional title, higher than that among the staff in community-level (42.28%); and 69.90% staff in district-level institution had more than 10 years of working experience, higher than that among the staff in community-level (43.62%). In the aspect of emergency drills and training, all district-level mental illness prevention and control institutions in Shanghai had a high demand for emergency training, and the weak aspects mainly focused on lack of emergency service protocols, skills of addressing technical challenges, and construction of effectiveness evaluation system. Moreover, the teaching methods were primarily centered on case analysis, simulation drills, interactive discussions, and so forth. Concerning emergency management plans and rules and regulations, all districts in Shanghai had relatively established well-developed systems for emergency response plans, emergency response leadership groups, and emergency response operational task forces for severe mental disorders. About half of the institutions had established other rules and regulations related to emergency management of severe mental disorders in addition to emergency plans. ConclusionShanghai has initially established an emergency management system for severe mental disorders, but it is still fragile in specialized training for emergency management of severe mental disorders, construction of emergency management mechanisms, and the building-up of grassroots emergency teams. Further priorities should include strengthening emergency management training, enhancing the construction of emergency management personnel teams, and gradually establishing a more comprehensive and integrated emergency management mechanism for severe mental disorders.

OBJECTIVE To evaluate the efficacy, safety and cost-effectiveness of generic drugs and original drugs of voriconazole. METHODS The information of patients who used voriconazole generic drugs selected in National Centralized Drug Procurement (generic drug group) or non-selected original drugs (original drug group) in the treatment of fungal infection was collected from the our hospital. The propensity score matching was carried out to eliminate bias. The comprehensive efficacy was evaluated according to clinical efficacy, image findings and microbiological test, and stratified analysis of different populations was conducted based on fungal species, underlying diseases, etc., the efficacy of different stratifications was evaluated. Evaluation of safety was performed by using the incidence of adverse reactions. The total cost, defined daily doses (DDDs) and defined daily dose cost (DDDc) were used to evaluate the cost-effectiveness. RESULTS A total of 436 patients were included, and there were 190 patients in each group after matching. In terms of efficacy, the effective rates of voriconazole generic drugs and original drugs were 62.63% and 59.47% (P=0.528); in terms of safety, the incidence of adverse reactions caused by generic drugs and original drugs of voriconazole was 13.68% and 7.89%, respectively(P=0.069). In terms of cost-effectiveness, the average total cost of generic drugs was 4 636.26 yuan, and that of original drugs was 8 613.20 yuan (P<0.001). After the implementation of National Centralized Drug Procurement, replacement rate of generic drugs increased to 87.30%, and DDDc decreased by 59.08%. CONCLUSIONS The efficacy and safety of voriconazole generic drugs are similar to those of original drugs in the treatment of fungal infection, and it is more cost-effective in terms of treatment cost.

BACKGROUND:Exercise has been widely recognized in the prevention and treatment of diabetes.Aerobic exercise has become an important part of the treatment of type 1 diabetes.However,the effect of treadmill exercise on the metabolism and chronic neuroinflammation of type 1 diabetes in different sexes needs further discussion. OBJECTIVE:To study the effects of treadmill exercise on metabolism and chronic neuroinflammation in type 1 diabetes mice of different sexes. METHODS:Forty C57BL/6 mice were divided into male group and female group,with 20 mice in each group.Then,a diabetes model was established by continuous injection of streptozotocin at 80 mg/kg for 3 days.Ten rats from each group were randomly selected to perform 6-week treadmill exercise as the diabetes+exercise group and another 10 rats from each group were selected as the diabetes group.Serum sex hormones,liver tissue oxidative stress,brain tissue inflammatory factors,and liver pathology were detected,and Morris water maze was performed for the observation of behavioral changes in mice. RESULTS AND CONCLUSION:Compared with the diabetes group,the diabetes+exercise group delayed the rise of blood sugar in type 1 diabetes mice(P<0.05)and showed a significant reduction in serum follicle-stimulating hormone,luteinizing hormone,liver superoxide dismutase,malondialdehyde,brain tumor necrosis factor α,interleukin-6 and interleukin-1β levels(P<0.01),while serum estradiol,progesterone,estrogen,and liver glutathione peroxidase protein levels were significantly increased(P<0.01,P<0.05).Compared with male type 1 diabetes mice,female type 1 diabetes mice had significantly higher estradiol levels and lower luteinizing hormone levels(P<0.05).Compared with the male diabetes+exercise group,the female diabetes+exercise group had lower liver glutathione peroxidase levels(P<0.05).Compared with type 1 diabetes mice,the escape latency of exercise training mice was shorter(P<0.01).In male mice,exercises significantly increased the time and platform crossing times of type 1 diabetes mice in the target quadrant(P<0.01 or P<0.05),while in female mice,exercises significantly increased the time of type 1 diabetes mice in the target quadrant(P<0.05).Correlation analysis results showed that the levels of follicle-stimulating hormone,luteinizing hormone,progesterone,superoxide dismutase,malondialdehyde,tumor necrosis factor α,and interleukin-6 were positively correlated with the level of interleukin-1β(P<0.05 or P<0.01),whereas the levels of estradiol and progesterone were negatively correlated with the levels of superoxide dismutase,malondialdehyde,tumor necrosis factor α,interleukin-6 and interleukin-1β(P<0.05 or P<0.01).Overall,there are sex differences in the effects of treadmill exercise on metabolic indicators and chronic neuroinflammatory regulation in diabetes mice.Sex hormones are an important variable of treadmill exercise in the metabolic,inflammatory and cognitive responses in diabetes mice.

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.
