Objective To discuss and to compare the curative effects of interventional embolization with different embolic agents in treating giant hepatic cavernous hemangiomas. Methods From 2008 to 2010, a total of 30 cases with clinically proved hepatic cavernous hemangioma were treated with interventional embolization. According to the embolic agents used , the patients were divided into pingyangmycin-lipiodol emulsion mixed with sodium alginate microspheres group(PLE+KMG, group A, n=15) and pingyangmycin-lipiodol emulsion group (PLE, group B, n=15). CT scanning was performed one, 3, 6, 12 months after the treatment to evaluate the curative effect. Results The technical success rate was 100%in both groups. The mean PLE dose used in group A and B was (10.9 ± 5.2) ml and (11.4 ± 4.9) ml respectively, the difference between the two groups was not significant (P > 0.05). CT reexamination performed one, 3, 6 months after the treatment showed that a reduction in tumor volume over 50%in group A was seen in 9, 11 and 14 cases respectively, while in group B it was 0, 3 and 5 cases respectively (P <0.05). One week after the procedure, the degree of pain in patients of group A was more severe than that in patients of group B, the difference between the two groups was statistically significant (P < 0.05). Slight abnormal hepatic function was seen in some patients of both groups, which presented mainly as an elevation of aminotransferase, which returned to normal after symptomatic medication. Follow-up with questionnaire indicted that patients of group A were more satisfied with the treatment than the patients of group B. Conclusion Transhepatic infusion of pingyangmycin-lipiodol emulsion is a safe and effective treatment for giant cavernous hemangioma of the liver. Combination use of pingyangmycin-lipiodol emulsion and sodium alginate microspheres can obviously reduce the tumor size mainly in the first and the third month after the treatment, besides it produces instant clinical effect although the pain is more severe than in patients treated with pure pingyangmycin-lipiodol emulsion.

OBJECTIVETo review the development, mechanism, necessity and limitation of antiviral therapy in decompensated hepatitis B virus-related cirrhosis.

DATA SOURCESMost information was pulled from a literature search (Pubmed 2000 to 2011) using the keywords of antiviral and decompensated hepatitis B virus-related cirrhosis. Relevant book chapters were also reviewed.

STUDY SELECTIONWell-controlled, prospective landmark studies and review articles on antiviral therapy in decompesated hepatitis B virus-related cirrhosis were selected.

RESULTSSpecific antiviral agents not only control viral replication, which permits liver transplantation, but also improve liver function so significantly that patients could be removed from the transplant waiting list. However, the emergence of drug-resistant mutants can result in treatment failure. Combination therapy is a save-strategy in drug-resistant.

CONCLUSIONSAlthough the treatment of end-stage liver disease is still a challenge worldwide, antiviral therapy has altered the natural history of hepatitis B patients with decompensated cirrhosis. The approval of the new generation of antivirals is opening new perspectives for finding the optimal antiviral treatment for patients with decompensated cirrhosis and preventing antiviral resistance. A combination of antivirals may be one of the future strategies for fulfilling these goals.

COVID-19 epidemic continues to spread around the world till these days, and it is urgent to develop more safe and effective new drugs. Due to the limited P3 biosafety laboratories for directly screening inhibitors of virulent viruses with high infectivity, it is necessary to develop rapid and efficient screening methods for viral proteases and other related targets. The main protease (M^pro), which plays a key role in the replication cycle of SARS-CoV-2, is highly conserved and has no homologous proteases in humans, making it an ideal target for drug development. From two different levels, namely, molecular level and cellular level, this paper summarizes the reported screening methods of SARS-CoV-2 M^pro inhibitors through a variety of representative examples, expecting to provide references for further development of SARS-CoV-2 M^pro inhibitors.

OBJECTIVE: To study the distribution and proportion of neuropeptide containing nervers in the sinus node in cases of sudden manhood death syndrome (SMDS) and to explore the mechanism of SMDS. METHODS: Immunohistochemical staining and quantitative analysis of neuropeptide Y (NPY) and vasoactive intestinal peptide(VIP) in the sinus node in 6 cases of SMDS and in 12 cases of non-cardiac death(control group) were achieved by LSAB method and computerized image system. RESULTS: As for NPY positive materials, VIP positive materials and the ratio of VIP/NPY in the sinus nodes, there were no significant difference between the control group and SMDS group. CONCLUSION The mechanism of SMDS and the abnormality of autonomic nervous innervation in the sinoatrial nodes maybe incorrelation.

As a common protease with high similarity among coronavirus species, the main protease (M^pro) of SARS-CoV-2 is responsible for the catalytic hydrolysis of viral precursor proteins into functional proteins, which is essential for coronavirus replication and is one of the ideal targets for the development of broad-spectrum antiviral drugs. This paper reviews the main protease inhibitors of SARS-CoV-2, including their molecular structures, potencies and drug-like profiles, binding modes and structure-activity relationships, etc.

Objective To evaluate the commonly used consciousness scales according to longitudinal study on small-sample patients with minimally conscious state. Method Eleven patients with minimally consciousness, who were scanned using fMRI, were selected and scored by the commonly used consciousness scales in Wujing Hangzbeu Hospital. The 11 patients were classified into 2 groups according to the scores of CRS-R scale couple with the results of the fMRI study. The One-Way ANOVA method was used to analyze the inter-group difference of the commonly used consciousness scales and their subscales. Results Despite the communicative subscale of the CRS-R scales, other iterms lack of statistic significance in classification of the conscious state. Among the commonly used consciousness scales, the Wessex Head Injury Matrix (WHIM) scale presented the highest diagnostic value in consciousness state, whereas the Chinese Vegetative State Scale (CVSS) presented the lowest diagnostic value. Conclusions It indicated that the total scores of the consciousness scales and the scores of subscales of them presented poor diagnostic value in general, and big discrepancy of diagnostic value existed between the iterms of the scales by using objective tools.
