ObjectiveTo explore the medication patterns of Professor Zhang Farong in treating type 2 diabetes mellitus （T2DM） and the clinical efficacy of his core prescription. MethodsClinical case records of T2DM treated by Professor Zhang Farong were collected to establish a prescription database. Frequency statistics， visual analysis， and factor analysis were employed to investigate the characteristics and principle of the prescriptions， and a core prescription was derived. A randomized controlled trial was conducted， enrolling 60 T2DM patients with the dampness-heat syndrome. The patients were allocated into an observation group （core prescription + metformin） and a control group （metformin alone）， with both groups undergoing a 12-week treatment course. Changes in TCM symptom scores， glucose metabolism indicators ［fasting plasma glucose （FPG）， 2-hour postprandial blood glucose （2 hPG）， and glycated hemoglobin （HbA1c）］， pancreatic function indicators ［fasting C-peptide （FCP）， 2-hour postprandial C-peptide （2 hCP）， and area under the C-peptide curve （AUCcp）］， and lipid profiles were measured before and after treatment. The adverse reactions were observed and recorded. ResultsA core prescription named modified Gegen Qinlian Decoction was formulated， comprising Puerariae Lobatae Radix， Coptidis Rhizoma， Scutellariae Radix， Astragali Radix， Lycii Cortex， Mori Cortex， Jineijin Endothelium Corneum Gigeriae Galli， Rehmanniae Radix Praeparata， Atractylodis Rhizoma， Polygonati Rhizoma， and Pogostemonis Herba. The clinical trial results showed that both groups had significantly decreased FPG， 2 hPG， and HbA1c （P0.05）， and the observation group outperformed the control group in recovering the level of HbA1c （P0.05）. After treatment， both groups had declined TCM symptoms scores （P0.05）， and the declines in the observation group were larger than those in the control group （P0.05）. After treatment， the TC and LDL-C levels declined in the observation group （P 0.05）， while the lipid levels showed a decreasing trend with no statistically significant difference in the control group. After treatment， both groups showed increases in FCP and AUCcp （P0.05）， and the 2 hCP in both groups presented a recovering trend with no statistically significant difference. There was no statistically significant difference in the incidence of adverse reactions between the two groups. ConclusionModified Gegen Qinlian Decoction embodies Professor Zhang Farong's academic philosophy of treating consumptive thirst by tonifying the spleen and kidney， replenishing Qi and Yin， clearing deficiency and heat， unblocking stasis in collaterals， and addressing both deficiency and stasis. The combination of the core prescription with metformin alleviates clinical symptoms in T2DM patients with the dampness-heat syndrome， demonstrating potential effects in restoring pancreatic islet function， regulating blood glucose， and improving lipid profiles. It serves as a therapeutic option for T2DM in the patients with the dampness-heat syndrome under syndrome differentiation， meriting broader clinical application.

Background::T-cell-mediated immunity is crucial for the effective clearance of viral infection, but the T-cell-mediated immune responses that are induced by booster doses of inactivated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in people living with human immunodeficiency virus (PLWH) remain unclear.Methods::Forty-five PLWH who had received antiretroviral therapy (ART) for more than two years and 29 healthy controls (HCs) at Beijing Youan Hospital were enrolled to assess the dynamic changes in T-cell responses between the day before the third vaccine dose (week 0) and 4 or 12 weeks (week 4 or week 12) after receiving the third dose of inactivated SARS-CoV-2 vaccine. Flow cytometry, enzyme-linked immunospot (ELISpot), and multiplex cytokines profiling were used to assess T-cell responses at the three timepoints in this study.Results::The results of the ELISpot and activation-induced marker (AIM) assays showed that SARS-CoV-2-specific T-cell responses were increased in both PLWH and HCs after the third dose of the inactivated SARS-CoV-2 vaccine, and a similar magnitude of immune response was induced against the Omicron (B.1.1.529) variant compared to the wild-type strain. In detail, spike-specific T-cell responses (measured by the ELISpot assay for interferon γ [IFN-γ] release) in both PLWH and HCs significantly increased in week 4, and the spike-specific T-cell responses in HCs were significantly stronger than those in PLWH 4 weeks after the third vaccination. In the AIM assay, spike-specific CD4 + T-cell responses peaked in both PLWH and HCs in week 12. Additionally, significantly higher spike-specific CD8 + T-cell responses were induced in PLWH than in HCs in week 12. In PLWH, the release of the cytokines interleukin-2 (IL-2), tumour necrosis factor-alpha (TNF-α), and IL-22 by peripheral blood mononuclear cells (PBMCs) that were stimulated with spike peptides increased in week 12. In addition, the levels of IL-4 and IL-5 were higher in PLWH than in HCs in week 12. Interestingly, the magnitude of SARS-CoV-2-specific T-cell responses in PLWH was negatively associated with the extent of CD8 + T-cell activation and exhaustion. In addition, positive correlations were observed between the magnitude of spike-specific T-cell responses (determined by measuring IFN-γ release by ELISpot) and the amounts of IL-4, IL-5, IL-2 and IL-17F. Conclusions::Our findings suggested that SARS-CoV-2-specific T-cell responses could be enhanced by the booster dose of inactivated COVID-19 vaccines and further illustrate the importance of additional vaccination for PLWH.

In order to obtain polyclonal antibodies against the fibrillar(Fiber)protein of fowl ade-novirus serotype 11(FAdV-11)and investigate its cross-reactivity to different serotypes of FAdV Fiber,the gene encoding the FAdV-11 Fiber protein was cloned into a prokaryotic expression vec-tor pET-32a by homologous recombination technology,then the plasmid was transformed into BL21(DE3)receptor cells,and the purified recombinant protein was used as an immunogen to im-munize rabbits to prepare polyclonal antibody after induced expression,and the cross-reactivity of the polyclonal antibody against different serotypes of FAdV Fiber proteins was identified by West-ern blot and indirect immunofluorescence(IFA).The results showed that the His-FAdV-11-Fiber recombinant protein was mainly expressed as inclusion bodies and was well expressed.Western blot and IFA showed that the prepared polyclonal antibody reacted with the Fiber proteins of FAdV-8a,FAdV-8b,and FAdV-11,but did not with the 2 Fiber of FAdV-4(Fiber 1 and Fiber 2)proteins.In conclusion,in this study,we successfully prepared rabbit polyclonal antibodies against FAdV-11 Fiber and showed that it specifically recognized the Fiber proteins of FAdV-8a,FAdV-8b and FAdV-11,which lays the foundation for further establishment of serological differential diag-nosis of FAdV-11.

Circular RNA(circRNA)represents a unique class of closed-loop structured non-coding RNAs involved in various biological processes such as cell proliferation,differentiation,and apopto-sis.They play a significant role in the development of numerous diseases,and also serve as poten-tial biomarkers and therapeutic targets.To explore the impact of circRNA on viral replication,this study performed an omics measurement and analysis of circRNA differential expression in MC38 cells infected with HY12 enterovirus.It was found that,following HY12 virus infection,the ex-pressionlevels of 570 circRNAs were upregulated,while 381 circRNAs were downregulated.A-mong the upregulated circRNAs,the significantly upregulated circRNA mmu_circ_0001083 was selected for further investigation into its association with HY12 infection and its impact on viral replication.The results indicated that after HY12 virus infection,the expression of host circRNA mmu_circ_0001083 significantly increased,and its expression level was dependent on the virus dos-age and time.Compared to normal MC38 cells infected with the HY12 virus,cells with knocked down expression of circRNA mmu_circ_0001083 showed reduced expression of the 2C protein and significantly lower viral titers.Conversely,after HY12 virus infection in MC38 cells with overexpressed circRNA mmu_circ_0001083,there was an increase in the expression of the 2C pro-tein and a significant rise in viral titers.These results suggest that the upregulation of host cir-cRNA mmu_circ_0001083 is significantly positively correlated with the replication of HY12 virus,meaning mmu_circ_0001083 plays a positive regulatory role in the replication of HY12.This find-ing lays a foundation for future in-depth studies on the regulatory mechanisms of circRNA on viral replication.

Objective To explore the effects of monocular deprivation(MD)on the expression of astrocytes in the superior colliculus,hippocampus,and visual cortex in mice during the critical period of visual development.Methods Eighteen C57BL/6J mice were randomly divided into the normal control group(CON group)and the MD group,with 9 mice in each group.Mice were bred under the 12 h/12 h dark/light conditions.Mice in the CON group received no treat-ment,while mice in the MD group underwent MD of the right eye on postnatal day 27,and the tissue was removed after 7 days.The mRNA and protein expression levels of glial fibrillary acidic protein(GFAP)in the superior colliculus,hippo-campus and visual cortex of mice in the two groups were detected using the real-time reverse transcription quantitative pol-ymerase chain reaction(RT-qPCR)and Western blot,respectively.The number of astrocytes labeled by GFAP and central nervous system specific protein β(S100β)in the superior colliculus,hippocampus and visual cortex of mice in the two groups was detected using the immunofluorescence staining.Results RT-qPCR and Western blot results showed that compared with the CON group,the mRNA and protein expression levels of GFAP in the superior colliculus,hippocampus(CA1,CA3 and dentate gyrus)and visual cortex of mice in the MD group decreased,and the differences were statistically significant(all P＜0.05).The immunofluorescence staining results showed that compared with the CON group,the number of GFAP and S1OOβ co-labeled astrocytes in the superior colliculus,hippocampus(CA1,CA3 and dentate gyrus)and visual cortex of mice in the MD group decreased,and the differences were statistically significant(all P＜0.05).Conclusion MD of mice during the critical period of visual development can result in a decrease in the number of astrocytes in the supe-rior colliculus,hippocampus and visual cortex.
