Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

"Education and Training Plan for Excellent Doctors" requires that the undergraduates of "The Five-year Clinical Medicine Undergraduates Training Model Reform Pilot Projects" must achieve four requirements: science and academy, clinical ability, health and society, and professional attainments. In view of the problems found in the education reform, combined with the characteristics of our school's own practices, we have adopted "organ-system-centered" integrated curriculum teaching model, student-centered online and offline teaching process, and applied the formative evaluation system to cultivate the core quality of Chinese students' development, which can improve the students' ability to find and solve practical problems.

Objective: To optimize the ultrahigh pressure extraction ( UPE) process for forsythoside from Forsythia suspensa by Box-Behnken experimental design. Methods:On the basis of single factor screening, a three-factor and three-level Box-Behnken ex-perimental design was employed with liquid/material ratio( X1 ) , extraction pressure ( X2 ) and extraction time ( X3 ) as the independent variables. The response variable was the extraction yield of forsythoside. Results:The optimal UPE conditions for forsythoside were as follows:the ratio of solvent to material (ml·g-1) was 70, the extraction pressure was 151 MPa, and the extraction time was 114 s. With the optimal extraction process, the extraction yield of forsythoside was 13. 15 mg·g-1 . Conclusion:As a novel extraction tech-nology for Chinese herbal medicines, UPE procedure has higher extraction yield, lower extraction temperature, shorter extraction time and less power consumption, which provides a brand-new method for the extraction of forsythoside from Forsythia suspensa.

ObjectiveTo explore the expression of CD3+ CD8+ human leukocyte antigen (HLA)-A2+T lymphocytes with specificity to the different hepatitis B virus (HBV) peptides in the peripheral blood mononuclear cells (PBMC)from the patients with hepatitis B associated hepatocellular carcinoma (HCC).MethodsThe HLA-A2+ PBMC from four patients with hepatitis B associated HCC were incubated with five HBV/HLA-A2 pentamers respectively,which were HBV sAg (FLLTRILTI),HBV sAg (GLSPTVWLSV),HBV sAg (WLSLLVPFV),HBV core (FLPSDFFPSV),and HBV pol (FLLSLGIHL),as well as anti-CD3-pacific blue and anti-CD8-fluorescein isothiocyanate (FITC).Then,HBV/HLA-A2-CD3-CD8 positive cells were detected by flow cytometry. The monoclonal HBV/HLA-A2-CD3-CD8+ cells were acquired by fluorescenceactivated cell sorter,and cultured and identified by flow cytometry.The anti-HBV specific T lymphocytes were then cultured with HepG2 (HLA-A2+ ) cells and the release of interferon γ (IFN-γ)were determined by enzyme-linked immunosorbent assay (ELISA),Res(a)ltsThe percentage of antiHBV T lymphoeytes with specificity to GLSPTVWLSV in total CD8+ T lymphoeytes from four patients with hepatitis B associated HCC was 1.44％±0.04％,which was higher than those to other four HBV antigen peptides (0.68％±0.08％ of FLLTRILTI,1.06％±0.09％ of FLPSDFFPSV,0.56％ ±0.04％ of FLLSLGIHL,and 0.46％ ±0.08％ of WLSLLVPFV) (t=0.001,P＜0.05).The two lines of monoclonal cell with specificity to GLSPTVWLSV both exhibited high level of IFN-γ expression after incubated with hepatic carcinoma cell line HepG2 (HLA-A2+)with HBV GLSPTVWLSV peptide.ConclusionsCD3+ CD8+ HLA-A2+ cells with specificity to the different HBV peptides exist in PBMC of patients with hepatitis B associated HCC.The expression level depends on HBV antigen peptide sequences and genomic sites.

Objective To investigate and compare the features of the HIV-1-specific CTL responses among three HIV-infected groups with varied infection history. Methods Three HIV-infeeted groups were enrolled in this study, including two groups infected by blood transmission (one group has been infected for more than 10 years and the other for 1-2 years) and one group of the man who have sex with man. The HIV-1-specific CTL responses were quantified by an IFN-γ based ELISPot assay with a peptide matrix system containing overlapping peptides spanning the entire HIV-1 Clade B genomic consensus sequences. Results The responding rate of CTL responses against all 17 peptide pools among the group that infected 1-2 years,the group infected more than 10 years and the group of MSM were 40% ,65% ,23%. One way ANOVO analysis showed that the responding rate of CTL responses against all 17 peptide pools were statistical significant among the three groups (F=19.96, P＜0.01);the magnitude of CTL responses of the three groups were 0-5 835 SFCs/106 PBMC, 0-7 225 SFCs/106PBMC, 0-9 740SFCs/106pBMC, Kruskal-Wallis test showed that the magnitude of CTL responses were statistical significant among the three groups( H = 101.90 , P ＜0.01);the breadth of CTL were 7 ( 2-11 ), 11(9-14) and 4 (2-6) respectively and Kruskal- Wallis test showed that the breadth of CTL had no statistical significant among the three groups( H = 34. 75 ,P ＜0. 01 ). The sequence of responding rate, magnitude and breadth of CTL from high to low was the group that had been infected for more than 10 years, the group infected 1-2 years and the sex transmission group. The common characteristics of the CTL response among the three groups were that the responding rate and the magnitude of the peptide Nef and Gag was higher than other peptide's. The magnitude of CTL responses among three different CD4count groups (CD4 ＜ 200/μl, CD4 200-500/μl, CD4 ≥500/μl,) was 0-18 475 SFCs/106pBMC, 350-34 095 SFCs/106pBMC, 490-21 550 SFCs/106 PBMC and had no statistic difference among the three different CD4 groups(H=2.93, P=0.23) while the breadth of CTL was 3(0-8), 10(2-17), 10 (1-17)respoctively and the breadth of CTL was lower in the group of CD4 count less than 200/μl than the other two groups( H = 14. 72, P ＜ 0. 01 ). The magnitude of CTL responses among three different viral load (VL)groups (VL＜ LDL, LDL ＜ VL ＜ 1 × 104 copys/ml, VL≥1 ×104 copys/ml) was 490-18 475 SFCs/106pBMC, 0-24 115 SFCs/106pBMC, 770-34 095 SFCs/106 pBMC and had no statistic difference among the three different viral load groups ( H = 0.79, P=0.67) and the breadth of the three different viral load groups CTL was 8( 1-17), 11 (0-17), 8 (1-16) and Kruskal-Wallis test showed that there was no statistic difference among the three different viral load groups (H =5.27, P =0. 07). Conclusions All groups predominantly develope T cell immune responses against Nef and Gag proteins. With the elapse of HIV infection, the CTL responses are increased in both magnitude and responding rate. This information is important for vaccine development.

Objective To construct two DNA vaccines encoding Gag-Env fusion protein and Tat-Rev-Integrase(C-half)-Vif-Nef fusion protein derived from the first HIV-1 CRF01_AE isolate(AE2f) in Chi-na and to evaluate the immunogenicity in mice. Methods Two DNA vaccines were constructed by inserting the codon optimized and synthesized gag-env fusion gene and tat-rev-integrase(c-half)-vif-nef fusion gene de-rived from AE2f into mammalian expression vector pDRVISV1. 0, the generated DNA vaccines were desig-nated as pSVAE/GE and pSVAE/TRIVN, respectively, and their in vitro expression were determined by Western blot with transfected 293T cells. Mice were i. m. immunized with either pDRVI1.0 as mock control, pSVAE/GE or pSYAE/TRIVN for 4 times at two-week interval. Two weeks following the final im-munization, cellular responses to pool of HIV-1 Env, Gag, Tat, Rev, Intergrase, Vif and Nef peptides were evaluated by ELISPOT assay. Results The construction of DNA vaccine pSVAE/GE and pSVAE/TRIVN was validated by restriction enzyme digestion and bidirectional sequencing. Western blot showed a specific band at molecular mass 220×10~3 in lane of pSVAE/GE transfeeted 293T cell and a specific band at 95×10~3 in the lane of pSVAE/TRIVN. Both DNA vaccines mounted significant specific T cell responses with (3010 ± 566) SFC/10~6 splenocytes for DNA vaccine pSV AE/GE and (948 ± 737) SFC/10~6 spleno-cytes for DNA vaccine pSVAE/TRIVN, whereas the mock control of pDRVISV1.0 only raised marginal T cell responses. Conclusion Both pSVAE/GE and pSVAE/TRIVN were capable of expressing the inserted fusion immunogen genes and able to elicit vigorous cellular immune responses, therefore, these DNA vac-cines are highly immunogenic.
