Objective:To investigate the serum level of miR-224 in hepatocellular carcinoma (HCC) patients and its clinical diag-nostic significance. Methods:The serum level of miR-224 was detected by real-time quantitative PCR. This study included 42 cases of patients with HCC, 36 patients with liver cirrhosis (LC), 55 patients with chronic hepatitis B (CHB), and 40 healthy persons (NC). The relative expressions of miR-224 were calculated. The receiver operating characteristic (ROC) curves were analyzed to determine the sensitivity and specificity of miR-224 expression levels in HCC diagnosis. Results:Result shows that the relative miR-224 expression was higher in the serum of HCC patients than that in the CHB, LC, and NC groups. The difference was statistically significant (P<0.05 or P<0.01). The relative miR-224 expression in the serum of HCC patients and alpha fetoprotein (AFP) were positively correlated (P<0.05). By comparison, the tumor size, TNM stage, tumor differentiation, and lymph node metastasis were not correlated with mirR-224 expression (P>0.05). ROC analysis shows that the best critical value of the relative expression levels of miR-224 was 3.47, with sensi-tivity of 82.2%, specificity of 92.8%, and area under the curve of 0.935. Conclusion:The serum level of miR-224 in HCC patients has high specificity, and miR-224 has great potential to become a new serological marker for the diagnosis of HCC.

Abstract: Objective To detect the antibody levels of hantavirus in serum samples from patients suspected with hemorrhagic fever with renal syndrome (HFRS) in Heilongjiang Province from 2019 to 2021, and to provide scientific basis for the prevention and control of disease. Methods Enzyme-linked immunosorbent assays (ELISA) were used to detect the IgM antibodies to hantavirus in serum samples collected from suspected patients with HFRS in the acute-phase, and IgM and IgG antibody in convalescent-phase serum samples. The positive rate of IgM antibody in acute-phase serum samples of patients in different years was analyzed with χ2 test by SPSS 19.0, and the data were sorted out and analyzed about patients' gender, occupation, age, date of onset and interval from onset to initial diagnosis by EpiData 3.1, Excel 2003 software. Results A total of 351 acute-phase serum samples and 208 convalescent-phase serum samples were detected in patients suspected with HFRS, respectively. There were 317 positive IgM antibodies of serum samples in the acute stage, with the positive rate of 90.31%. There was no significant difference in the positive rate of IgM antibodies in the acute stage between different years (χ2=0.895, P=0.639). T The IgM antibodies and IgG antibodies were positive in 32 (15.39%) and 28 (13.46%) of the convalescent-phase serum samples, respectively. Moreover, 148 patients (71.15%) were double-positive for IgM and IgG antibodies at the convalescent stage. The ratio of male to female patients was 4.56∶1, for which male patients were much more than female patients. Occupation was dominated by farmers (253 cases, 79.81%), followed by workers (19 cases, 5.99%) and the unemployed (17 cases, 5.36%), respectively. The age of patients ranged from 10 to 88 years old, with a median age of 49 years old. Most of the patients were in the age group from 30 years old to 60 years old (209 cases, 65.93%), among which the age group from 40 years old to 50 years old (86 cases, 27.13%) had the highest proportion, and the age group from 60 years old to 90 years old had a proportion of 20.18% (19 cases). May and November were the peak periods of HFRS in Heilongjiang Province. The median interval between onset and initial diagnosis was 4 days. Conclusions There is a gap of about 10% between the clinical diagnosis of HFRS cases and the confirmed cases detected by laboratory in Heilongjiang Province from 2019 to 2021. The virus-specific detection results are important for confirming the diagnosis of local patients with HFRS.

Objective To discuss the therapeutic strategy and the clinical efficacy of percutaneous cholecystostomy in treating high-risk patients with acute cholecystitis. Methods During the period of Jan. 2006-June 2008,percutaneous cholecystostomy was performed in 27 high-risk patients with acute cholecystitis,consisting of lithic cholecystitis (n = 21) and non-lithic cholecystitis (n = 6). Of 27 patients,percutaneous cholecystostomy via transhepatic approach was performed in 22 and via transperitoneal approach in 5. The 7 F drainage catheter was used. Cholecystography was conducted before the drainage catheter was extracted. Results Percutaneous cholecystostomy was successfully accomplished in all 27 cases,with a technical success rate of 100%. Postoperative patency of gallbladder drainage was obtained in 25 patients,with the relieving or subsiding of abdominal pain and the restoring of temperature and leukocyte account to normal range within 72 hours. In one patient,as the abdominal pain relief was not obvious 72 hours after the procedure,cholecystography was employed and it revealed the obstruction of the drainage catheter. After reopening of the drainage catheter,the abdominal pain was relieved. In another case,cholecystography was carried out because the abdominal pain became worse after the procedure,and minor bile leak was demonstrated. After powerful anti-infective and symptomatic medication,the abdominal pain was alleviated. The drainage catheter was extracted in 25 patients 6-7 weeks after the treatment. Of these 25 patients,12 accepted selective cholecystectomy,7 received percutaneous cholecystolithotomy and 6 with non-lithic cholecystitis did not get any additional surgery. The remaining two patients were living with long-term retention of the indwelling drainage-catheter. Conclusion Percutaneous cholecystostomy is a simple,safe and effective treatment for acute cholecystitis in high-risk patients. This technique is of great value in clinical practice.
