Objective To verify whether the periodic or continuous exposure to high glucose may have different effects on human umbilical vein endothelial cell (HUVEC)apoptosis, and to explore the effect of NF-κB pathway on apoptosis of HUVEC induced by high glucose using the RNAi adenovirus vector. Methods RNAi combinant adenovirus vector which targeted 1566 site of NF-κB p65 mRNA was constructed and the effect of p65 gene knockdown in HUVEC was detected by Western blot analysis. Then, the RNAi adenovirus was transducted to explore the role of NF-κB pathway on the regulation of apoptosis in HUVEC induced by high glucose. The apoptosis of HUVEC was tested by flow cytometry and TUNEL assay. Results High glucose could induce apoptosis of HUVEC. p65 protein expression of nuclear extracts was significantly increased in high glucose culture as compared to control group, but only slightly increased in NF-κB-specific knockdown group, which maintained at basal state. Compared with normal glucose group, the number of TUNEL-positive cells in high glucose group was significantly increased (25.81%±1.77% vs 8.20%±0.63%, P<0.05). The number of TUNEL-positive cells was decreased in 30.5 rmnol/L glucose plus Ad-1566 than that in 30.5 mmol/L glucose plus Ad-DEST (11.49%±0.92% vs 26.10%±0.98%, P<0.01). Flow cytometry and TUNEL assay showed that the apoptosis of human umbilical vein endothelial cells induced by high glucose was inhibited by the RNAi adenovirus. Conclusion High glucose induces apoptosis of HUVEC. Knockdown of NF-κB p65 may protect HUVEC from apoptosis by preventing high glucose-induced NF-κB nuclear translocation.

Objective:
To assess the risk of public health emergencies in Zhejiang Province, March 2021.
Methods:
An expert counsel was conducted to assess the risk of coronavirus disease 2019 ( COVID-19 ) , enteritis due to norovirus, chicken pox and influenza by professionals in Zhejiang CDC, based on the information from infectious disease and public health emergency surveillance in Zhejiang Province, domestic health administrative departments, World Health Organization, and European CDC.
Results:
In March 2021, the risk of imported COVID-19 epidemic will be high in Zhejiang Province, and the possibility of local spread could not be ruled out. The possibility of a large-scale outbreak of enteritis due to norovirus and a small-scale outbreak of chickenpox in schools and kindergartens could not be ruled out after the new term begins. An increased risk of influenza epidemic is predicted in collective units such as schools and kindergartens, yet the risk of a large-scale one will be low.
Conclusion
High attention should be paid to COVID-19 and enteritis due to norovirus, and general attention should be paid to chicken pox and influenza outbreak.

Objective:To analyze whether the sample of elderly subjects in clinical trials of prostate cancer drugs is representative.Methods:From the level of trial design, the age distribution of subjects in clinical trials of prostate cancer drugs for elderly patients from January 2019 to December 2021 was inquired on the platform of drug clinical trial registration and information disclosure.From the actual enrollment level, the prostate cancer drug clinical trials initiated and completed by a hospital from January 2010 to June 2022 were collected.The age information of subjects in all centers was collected for multicenter trials with a summary report, and the age data of subjects in the center was collected for trials without a summary report or single-center trials.The average age of prostate cancer onset and the incidence of prostate cancer in different age groups were compared with the Chinese Cancer Registry System, so as to compare whether the two were consistent.Results:Most of the trials(72.1%、44/61)did not set upper age limit at the protocol design level.Phase Ⅲ and phase Ⅳ trials did not set an upper age limit for enrolled subjects in the protocol.From the actual enrollment level, a total of 19 studies were included in this study, with 1 402 subjects, and the average age of subjects was 67.1±8.6 years old, which was significantly different from the average age of prostate cancer in China and Beijing(all P<0.001). The age group with the largest number of participants was 60-64 years old(34.2%、479/1 402). The population aged ≥75 years was the least(21.5%, 301/1 402), which was different from the high incidence age group of prostate cancer in China in 2017(421.77/100 000). Conclusions:Clinical trials of prostate cancer drugs are designed to cover all age groups of elderly patients, but the actual sample representation of the enrolled elderly subjects is insufficient.Under the premise of protecting the safety of subjects, the trial population who are matched for the average age of prostate cancer onset and the incidence of prostate cancer in age groups, should be gradually increased.

OBJECTIVETo investigate the effect of semen-derived enhancer of virus infection (SEVI) on the infection of transmitted/founder (TF) HIV-1 and its matched chronic control (CC) viruses and the antagonism of ADS-J1 on SEVI-mediated enhancement of TF and CC virus infection in vitro.
METHODSPAPself-assembling into SEVI amyloid fibrils was validated by ThT assay. We generated the virus stocks of TF and CC virus pair. TZM-bl cells were infected with the mixture of SEVI and TF or CC viruses for 72 h. Luciferase activity was used to observe the enhancement of SEVI. SEVI was treated with different concentrations of ADS-J1 and incubated with TF or CC viruses. TZM-bl cells were then infected with the mixture and luciferase activity was detected 72 h after infection to analyze the antagonism of ADS-J1 on the enhancing effect of SEVI. ADS-J1 was also incubated with TF and CC viruses directly and TZM-bl cells were infected for 72 h to evaluate the antiviral effect using luciferase assay. SEVI was treated with ADS-J1 and Zeta potential was determined to explore the antagonistic mechanism of ADS-J1.
RESULTSThT assay showed that PAPwas capable of self-assembly into SEVI amyloid fibrils. SEVI significantly accelerated TF and CC viruses infection (P<0.05), and ADS-J1 not only significantly antagonized the enhancement of SEVI (P<0.05) but also directly inhibited the infection of TF and CC viruses (P<0.05). ADS-J1 neutralized the positive charge of SEVI in a dose-dependent manner.
CONCLUSIONSSEVI promotes the infection of TF and CC strains, and ADS-J1 antagonizes SEVI-mediated enhancement of TF and CC viruses by neutralizing the positive charge of SEVI.

In order to investigate the relation of serum immunoglobulin (Ig) level to age, sex, disease stages and prognosis in chronic lymphocytic leukemia (CLL) patients, the levels of serum IgG, IgA and IgM in 83 CLL patients were detected by immune rate turbidimetry. the expressions of CD38 and ZAP-70 in CLL cells were determined by multi-parameter flow cytometry (FCM). The results showed that among the 83 CLL patients, the IgG, IgA and IgM levels were reduced in 12 (14.5%), 26 (31.3%) and 34 cases (41.0%) respectively. The incidence of Ig reduction was higher in Binet C stage than that in Binet A and B (p=0.011). There was higher incidence of Ig reduction in high-risk group of Rai stage than that in low-risk group (p=0.011). The positive rate of CD38 or ZAP-70 was significantly higher in Ig reduction group than that in normal Ig level group (p=0.033 and p=0.038 respectively). The positive rate of CD38 and ZAP-70 was also higer in advanced disease, and among them the positive rate of ZAP-70 expression in Binet C stage was obviously higer than Binet A and B (p=0.047). Nonetheless, there was no significant relationship of Ig level with gender and age (p>0.05). It is concluded that the function of humoral immunity in CLL patient is closely related to the disease stages. The serum Ig detection seems important for evaluating immunologic state and prognosis of CLL patients.
