Objective: To analyze the epidemiological characteristics of notifiable infectious diseases reported in Zhejiang Province in 2020 for prevention and control. Methods: Data of notifiable infectious diseases reported in Zhejiang Province in 2020 were extracted from China Information System for Disease Control and Prevention. The incidence and death of notifiable infectious diseases were analyzed and compared with the averages from 2015 to 2019; then the characteristics of some key diseases such as coronavirus disease 2019 ( COVID-19 ), influenza and other infectious diarrhea were summarized. Results: Totally 487 271 cases of 30 kinds of infectious diseases were reported. The incidence and mortality rate was 832.94/100 000 and 0.615 4/100 000, which were 7.05% and 14.60% lower than the average value of 2015-2019.The weekly morbidity of Class A and Class B infectious diseases fluctuated between 1.24/100 000 and 3.68/100 000, and hit the bottom in the sixth to eighth week. The morbidity of Class C infectious diseases was 154.19/100 000 in the first week, then dropped to 4.83/100 000 in the second to sixth week and maintained at a low level. High morbidity of infectious diseases were reported in Hangzhou ( 1 412.62/100 000 ), Jinhua ( 960.35/100 000 ) and Ningbo ( 921.25/100 000 ). The morbidity of class C infectious diseases in Hangzhou was 1 248.80/100 000, which was far higher than that of other ten prefecture-level cities. The diseases with high reported morbidity were influenza (438.45/100 000), other infectious diarrhea (140.29/100 000 ), hand-foot-and-mouth disease ( 99.64/100 000 ), pulmonary tuberculosis ( 41.92/100 000 ), syphilis (41.37/100 000) and viral hepatitis ( 30.48/100 000 ). More deaths were reported in AIDS and pulmonary tuberculosis, and the mortality were 0.482 1/100 000 and 0.116 2/100 000. A total of 1 306 confirmed cases, 302 asymptomatic infections and 1 death of COVID-19 were reported. Conclusion In 2020, the incidence rate of notifiable infectious diseases in Zhejiang decreased compared with the average value of 2015-2019. Pulmonary tuberculosis, syphilis and hepatitis B still have high morbidity, and the COVID-19 epidemic spread widely. The morbidity of some respiratory infectious diseases and imported infectious diseases have dropped significantly compared with previous years.

OBJECTIVETo explore the pathogenesis of postburn intestinal mucosal injury in scalded rats.

METHODSThe rats inflicted with full thickness burn were employed as the model. The two-dimensional electrophoresis (2-DE) was employed to identify the down-regulating proteins from the differential proteins in scalded rats. Spot detection and matching were performed with Image Master 2D Elite. Mass spectrometry was performed on Bruker BIFLEX III TOF.

RESULTSThere are 34 points of proteins in intestinal mucosa in scalded rats which were down-regulated at 6 and 12 postburn hours. Among them 22 proteins were employed for the identification and analysis. Mitochondrial aconitase, alpha-propionyl -CoA carboxylase heavy chain A of F1-ATPase in rat liver, Troponin short-chain of hydroxyacyl-coenzyme A dehydrogenase, alpha-subunit of P-electronic transferring flavoprotein (ETF) were down-regulating proteins correlated with mitochondria in intestinal mucosa in severely scalded rats. Triosephosphate isomerase 1 and cytosolic epoxide hydrolase were down-regulating proteins participated in metabolism of scalded rats. Fibromodulin, dynein-like protein, Troponin-2 and myosin light chain 3 alkali (MLC) were down-regulating proteins correlated with cellular skeletal protein. Glucocorticoid-inducible protein, nuclear factor1-B2, BRCA1, transcriptive factor EB (estradiol benzoate), beta2 subunit of G-protein, N-methyl-D-aspartate receptor1 (NMDAR) were down-regulating proteins participated in postburn regulation of intestinal mucosa in scalded rats. T-cell receptor-V-delta 6 and Ig heavy chain V region protein 1 were down-regulating proteins correlated with the immunomodulation of intestinal mucosa in scalded rats.

CONCLUSIONThe down-regulating proteins of intestinal mucosa in scalded rats exhibited close relationship with mitochondria.

To increase drug concentration in the head through intranasal administration, we have investigated the excised animal nasal mucosa permeability and nasal toxicity of the baicalin drug carrier systems, such as baicalin liposomes, beta-cyclodextrin inclusion compound, and phospholipid complex. A transport of baicalin drug carrier systems through nasal mucosa was simulated in diffusion chamber in vitro, and swine, caprine and rabbit nasal mucosa was used, the concentration of drug in the receptor was determined by HPLC. By taking the apparent permeability coefficients as evaluation standard, investigated the isolated animal nasal mucosa permeability of different baicalin drug systems was investigated for screening the best baicalin drug carrier system through nasal cavity administration. Toxicity of baicalin and its phospholipids complex on toad palate mucosal cilia movement and rats nasal mucosa long-term toxicity were studied in vivo. The apparent permeability coefficient of three kinds of baicalin drug carrier systems was better than that of baicalin (P < 0.05), and its lag-time was obviously shortened. At the same time, the apparent permeability coefficient of phospholipid complex was higher than those of other two drug carrier systems (P < 0.05). The results showed that the baicalin phospholipids complex nasal mucosa permeability was obviously superior to the other two drug systems. Baicalin phospholipids complex had no toxicity to ciliary movement, and had no irritation to rat nasal mucosa. The results show that baicalin phospholipid complex was the best baicalin drug carrier system, it could significantly enhance the permeability of baicalin across nasal mucosa, had no toxicity to nasal mucosa, and could be used for intranasal administration.

OBJECTIVETo investigate the expression of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9(MMP-9), transforming growth factor beta(1)(TGF-beta(1)) and IV-collagen (C-IV) in kidneys of diabetic rats.

METHODSRat diabetic model was induced by streptozotocin (70 mg/kg), and kidneys were examined pathologically and the expressions of MMP- 2, MMP-9, TGF-beta(1) and C-IV were studied by immunohistochemistry. The results were analyzed by imaging quantitative analysis technique.

RESULTImmunoreactive MMP-2 and MMP-9 were mainly expressed in the mesangial cells, endothelial cells, parietal layer of Bowman's capsule and tubular cells. The expression of MMP-2 was significantly weaker in the glomeluri of diabetic rats than that of the control animals (P<0.05), while the expression of TGF-beta(1) and C-IV in the glomeluri of diabetic rats was significantly stronger than that of the controls (P%lt;0.05). The expression of MMP-9 didn't show significant different in glomeluri of the two groups (P>0.05).

CONCLUSIONExpression of MMP-2 in glomeluri is decreased in diabetic rats, which may be related to the increased TGF-beta(1) and in turns promote the accumulation of C-IV.

The major capsid protein of lymphocystis disease virus isolated from Rachycentron canadum (LCDV-rc) was amplified and analysed. The 457bp DNA core fragment was amplified with the degenerate primers designed according to the conserved sequences of MCP gene of iridoviruses, then the flaking sequences adjacent to the core region were amplified by inverse PCR, and the complete sequence was obtained by combining all of them. The open reading frame of the gene is 1380bp in length, encoding a putative protein of 459 aa with molecular weight 51.12 kD and pI 6.87. Constructing the phylogenetic tree for comparing the MCP amino acid of iridoviruses, the results indicated that LCDV-rc is most homologous to the other Lymphocystis viruses and all of them constitute a branch. Accordingly LCDV-rc is identified as Lymphocystivirus.
