In chronic kidney disease (CKD), inflammatory responses during the progression of renal tissue and tissue injury related causes its progression to end-state renal disease. Among them, nuclear factor (nuclear factor, NF)-kappaB signaling pathway by regulating the corresponding nuclear expression of target gene transcription, as well as affecting the synthesis of inflammatory mediators, induction of inflammation lead to kidney damage and renal fibrosis. Some single herbs and their extracts (such as Astragali Radix, Scutellariae Radix, Ginkgo Folium) and some traditional Chinese medicine (such as Danggui Buxue decoction, Qilian decoction) can reduce the inflammatory damage induced by renal tissue NF-kappaB signaling pathway and delay the progression of CKD.

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 the echocardiographic features of operation-related aorto-cardiac fistula(ACF) after surgery or transcatheter procedure, to explore the value of echocardiography on diagnosis of operation-related ACF, and summarize the key points of its diagnosis.Methods:Eight patients with operation-related ACF who were admitted to Fuwai Hospital were collected from July 2002 to December 2020. Echocardiographic features of the 8 patients with operation-related ACF were reviewed and analyzed. The diagnosis methodology was summarized.Results:Of the 8 patients with operation-related ACF, 3 had aortic right atrial fistula and 5 had aortic right ventricular fistula. The fistula was single, which can be located but not limited to the aortic sinus. The median size of the fistula was 4 mm (range: 3-5 mm). There was no aneurysmal dilation of the aortic sinus where the fistula was located. The fractured end of the fistula did not thin, and the fistula had a regular shape. Six of the 8 patients undertook cardiac catheterization and occlusion. One patient received surgical repairment. One patient was treated conservatively.Conclusions:Echocardiography can help diagnose operation-related ACF and provide valuable information for further clinical diagnosis and treatment. Sonographers should avoid missed diagnosis and pay attention to distinguishing from other causes of aortic-cardiac shunt disease.

Background and aim:α-complex protein-2(αCP2)encoded by the poly(rC)binding protein 2(PCBP2)gene is responsible for the accumulation of type Ⅰ collagen in fibrotic livers.In this study,we silenced the PCBP2 gene using a small interfering RNA(siRNA)to reverse alcohol-and cytokine-induced profibrogenic effects on hepatic stellate cells(HSCs). Methods:Primary rat HSCs and the HSC-T6 cell line were used as fibrogenic models to mimic the initiation and perpetuation stages of fibrogenesis,respectively.We previously found that a PCBP2 siRNA,which efficiently silences expression of αCP2,reduces the stability of type Ⅰ collagen mRNA.We inves-tigated the effects of the PCBP2 siRNA on cell proliferation and migration.Expression of type Ⅰ collagen in HSCs was analyzed by quantitative real-time PCR and western blotting.In addition,we evaluated the effects of the PCBP2 siRNA on apoptosis and the cell cycle. Results:PCBP2 siRNA reversed multiple alcohol-and cytokine-induced profibrogenic effects on primary rat HSCs and HSC-T6 cells.The PCBP2 siRNA also reversed alcohol-and cytokine-induced accumulation of type Ⅰ collagen as well as cell proliferation and migration.Moreover,the combination of LY2109761,a transforming growth factor-β1 inhibitor,and the PCBP2 siRNA exerted a synergistic inhibitive effect on the accumulation of type Ⅰ collagen in HSCs. Conclusions:Silencing of PCBP2 using siRNA could be a potential therapeutic strategy for alcoholic liver fibrosis.

Objective This paper aimed to report the rate of suicide attempts among adolescent and young students of eight cities in China, and to examine the impact of related psychosocial factors on suicide attempts. Methods The investigation was obtained in senior and junior high school and college students in eight cities of China. All of the 17 622 participants were recruited to complete anonymous questionnaires regarding their experiences of suicide attempts and related psychosocial factors. Results Overall, 2.2 percent of the respondents reported that they had experienced attempted suicide during the previous year. Scores on high anxiety (OR=2.61,95%CI: 1.64-4.16),high depression (OR=2.05, 95%CI: 1.35-3.10),suicide idea (OR= 14.21, 95%CI: 9.88-20.43),suicide plan(OR=3.50,95%CI:2.59-4.73) were revealed as common risk factors while the whole time span being accompanied by mothers during juvenile years (OR=0.38, 95% CI: 0.20-0.74) seemed to be protective factor for suicide attempts through multivariate logistic regression analysis. Conclusion Our results showed that emotional symptom, idea and plans for suicide were statistically associated with suicide attempted in high school and college students.

OBJECTIVETo validate the hypothesis that the phenotypic transformation occurs in the smooth muscle cells in the corpus cavernosum of hypertensive rat and explore its impact on the erectile function of rats.
METHODSEighteen 16-week-old male spontaneously hypertensive rats (SHR) and 10 syngeneic normotensive rats (WKY) were used in this experiment. After measurement of systolic blood pressure of the caudal artery and examination of the erectile function with subcutaneous injection of apomorphine (APO), the rats were divided into 3 groups, namely hypertensive with erectile dysfunction (HBP-ED) group (n=6), hypertensive (HBP) group (n=12) and control group (n=10). Immunohistochemical staining and color image analysis system were used to observe expression of calponin 1 and osteopontin (OPN) in rat corpus cavernosum. Real-time quantitative RT-PCR was used to determine the expression of calponin 1 and OPN mRNAs in different groups.
RESULTSThe expressions of calponin 1 protein and mRNA were the highest in the control group and the lowest in HBP-ED group, while the expressions of OPN protein and mRNA were the highest in HBP-ED group and the lowest in the control group.
CONCLUSIONThe smooth muscle cells may transform from the contractile phenotype into synthetic phenotype in the corpus cavernosum of the hypertensive rats, resulting ultimately in erectile dysfunction.
