Green tea as a main beverage is consumed worldwide. In the last few years, .green tea has been shown to induce apoptosis and to inhibit the infiltration and metastasis of prostate cancer by in vitro and in vivo experiments. Epidemiologic investigations and clinical trials also have demonstrated the chemopreventive role of green tea in prostate cancer, such as reducing the possibility of carcinogenesis of high-grade prostatic in-traepithelial neoplasia, and is hopeful to be applied as chemopreventive agent of prostate cancer in the future.

?Retinal ischemia - reperfusion injury ( RlRl ) is a common clinical disease, and the producing mechanism is still in research. Experimental and clinical research in recent years have showed that the mechanism of RlRl and oxygen free radicals, gene regulation, calcium overload, inflammatory cytokines and other factors are closely related. ln this article, we summarized the current situation that the scholars at home and abroad study traditional Chinese medicine extract of prevention and treatment of RlRl.

Experiments on the use of ultrafiltration in the preparation of Shengmaiying oral liquid were carried out in comparison with the conventional preparation procedure. Results showed that the product obtained had abetter clarity and less impurities. It is postulated that such technique can be used in the purification of many oral liquid preparations of compounded herbal formulations with efficient removal of impurities while retaining the main active principles. The selection of ultrafiltration equipment,its optimum working pressure,temperature and filtration rate were discussed.

AIM: To express the DT389-hbFGF (389 amino acid residues of the N-terminus of diphtheria toxin (human basic fibroblast growth factor) fusion protein for potential targeting therapy towards posterior capsule opacification (PCO) after cataract surgery.METHODS: The DNA of inactivated diphtheria bacillus and RNA of 12-week fetal brain cortex were extracted, respectively. The fragments of truncated diphtheria toxin (containing 389 amino acids of N-terminus, DT389) )and full-length human basic fibroblast growth factor(hbFGF) sequence (encoding 18kDa protein) were amplified by PCR. The two fragments were inserted into pGEX-4T-1 prokaryotic expression vector to obtain pGEX-DT389-hbFGF prokaryotic expression plasmid. After sequence analysis, the expressing plasmid was transformed into Escherichia Coli BL21 strain and expression was induced under IPTG. The expressed fusion protein was purified and identified.RESULTS: The gene fragments encoding DT389 and hbFGF were amplified and their gene sequences were confirmed. Hybrid gene expression plasmid pGEX-DT389 (hbFGF was constructed. The fusion protein DT389-hbFGF was expressed and purified.CONCLUSIONS: The successful cloning and expression of DT389-hbFGF immunotoxin provides a foundation for targeting therapy towards posterior capsule opacification.

Abstract: Objective To analyze the epidemiological characteristics of outbreaks of infectious diseases in schools in Yunnan Province from 2004 to 2021, to provide a scientific basis for prevention and control strategies. Methods The data on outbreaks of infectious diseases in schools in Yunnan Province from 2004 to 2021 from the National Emergency Public Health Events Information Management System and on-site epidemiological surveys were collected and analyzed using descriptive epidemiology method. Results From 2004 to 2021, a total of 1 806 outbreaks of infectious diseases in schools in Yunnan Province was reported. The majority of the reports were of general events (90.25%), affecting 2 183 493 people with reported cases numbering 94 643 and 13 deaths. The main modes of transmission were respiratory infectious diseases. The top three reported diseases were chickenpox (588), influenza (300) and hand-foot-and-mouth disease (267), accounting for 64.0% of the total reported events. The events were distributed in 121 counties and districts throughout the province, concentrated in March–June and September–January of the following year. The main outbreaks were of chickenpox, with an average duration of 19 days. Most public health emergencies (1 386) occurred in kindergartens and primary schools, and the median time to discover the outbreak was 7 days (ranging from 4 to 13 days). Conclusions Respiratory infectious diseases are the main type of outbreak of infectious diseases in schools in Yunnan Province. Kindergartens and primary schools are the focus of prevention and control. Early reporting and effective handling will help control the spread of events and reduce hazards. At the same time, the prevention and control of school infectious diseases and the emergency drill of the plan during peak periods need to be particularly strengthened.

Objective To investigate the effects of inferior vena cava (IVC) filter placement for the prevention of fatal pulmonary embolism and to discuss the management of complications related to the filter placement. Methods Seventy patients with proved deep vein thrombosis of lower extremity underwent inferior vena cava filter placement. A total of 72 IVC filters were implanted, which included 20 Trap Ease filters, 31Vena Tech filters, 13 retrievable OptEase~(TM) filters and 8 Tempo Ⅱ filters. One filter was deployed above the orifice of renal vein and the remaining 71 were deployed below the orifice of renal vein. Results All the patients were followed up for 8-72 months after the procedure. During the follow-up period no fatal pulmonary embolism occurred except that some complications related to the filter placement occurred in 6 cases.Conclusion Inferior vena cava filter placement can effectively prevent the occurrence of pulmonary embolism. Of course, this treatment should be strictly applied according to the indications.

Objective To study the mechanisms of increasing amyloid [β1-42 (Aβ42) level by presenilin-1 (PS-1) mutation of V97L.Methods Expression level of neprilysin (NEP) in nontransfected, or mock vector, wild type (wt) PS-1 and V97L-PS-1-transfected SH-SY5Y cells were assessed by reverse transcriptional-polymerase chain reaction (RT-PCR) and Western blot.The level of Aβ42 was also assessed by enzyme linked immunosorbent assay (ELISA).Results The mRNA level of NEP was decreased significantly in PS-1 V97L transfected cells (0.650 ± 0.010) compared to that in normal cells (1.090 ± 0.015), wt PS-1 gene (1.040 ± 0.021) and mock (1.080 ± 0.020) stably transfected cell lines (t = 9.236, 10.452, 5.678; all P < 0.01).Although there was a decreased tendency in the protein expression of NEP in PS-Ⅰ V97L transfected cells (1.000 ± 0.126)compared to that in normal cells (1.020 ± 0.110), wt PS-1 gene (1.040 ±0.110), mock (2.130 ±0.130) stably transfected cell lines, nosignificant differences were found.The expression of Aβ42 was increased significantly in PS-1 V97L transfected cells compared to other cell lines (t = 2.109, 3.355, 3.976; all P < 0.01).Conclusions PS-1 V97L mutation can decrease the transcription of NEP, however, in contrast, this mutation also resulted in increased Aβ42.The mechanism needs further analysis.
