Objective: To analyze the nucleic acid load of human parvovirus B19 in major commercially available blood products in China, including human albumin, human intravenous immunoglobulin, human rabies immunoglobulin and various coagulation factor products, aiming to provide evidence for improving blood product manufacturing processes and quality control of source plasma. Methods: A total of 98 batches of coagulation factor products were tested for human parvovirus B19 nucleic acid using real-time fluorescent quantitative PCR, including 42 batches of human prothrombin complex, 35 batches of human coagulation factor Ⅷ, and 21 batches of human fibrinogen. Additionally, 6 batches of human albumin, 6 batches of human intravenous immunoglobulin, and 38 batches of human rabies immunoglobulin were tested for human parvovirus B19 nucleic acid. Results: Human parvovirus B19 nucleic acid were undetectable in human albumin, human intravenous immunoglobulin and human rabies immunoglobulin. Among the 98 batches of coagulation factor products tested for human parvovirus B19 nucleic acid, B19 nucleic acid reactivity rate was 69.0% (29/42) for human prothrombin complex batches, but nucleic acid concentration were all significantly lower than 10 IU/mL. The reactivity rate of B19 nucleic acid in 35 batches of human coagulation factor Ⅷ was 48.6% (17/35), with nucleic acid concentration all below 10 IU/mL. The reactivity rate of B19 nucleic acid in 21 batches of human fibrinogen was 61.9% (13/21), with nucleic acid concentration all below 10 IU/mL. Conclusion: No human parvovirus B19 has been detected in human albumin, human intravenous immunoglobulin, or human rabies immunoglobulin. Human parvovirus B19 nucleic acid may exist in commercially available coagulation factor products, highlighting the need for enhanced screening of human parvovirus B19 nucleic acid in these products. It is also recommended that B19 viral nucleic acid testing be conducted on source plasma, particularly for coagulation factor products.

Objective:To assess the correlation and consistency between the cancer risk-oriented endoscopic Kimura-Takemoto classification and the operative link for gastritis assessment (OLGA) in risk stratification of gastric cancer in patients with chronic gastritis after Helicobacter pylori ( H. pylori) eradication. Methods:From January 1, 2018 to October 31, 2021, 97 patients with chronic gastritis who successfully underwent H. pylori eradication at Beijing Friendship Hospital affiliated to Capital Medical University were selected. During the follow-up period, all patients underwent standardized magnifying endoscopy to assess gastric mucosal atrophy with the Kimura-Takemoto classification, which was classified as no or mild atrophy, moderate atrophy, and severe atrophy. Additionally, according to the new Sydney staging system, endoscopic biopsies were conducted at 5 sites of the patients to classify into OLGA stages 0, Ⅰ, Ⅱ, Ⅲ, or Ⅳ. Spearman rank correlation analysis and Kappa consistency test were performed to evaluate the correlation and consistency between the 2 evaluation systems, respectively. Area under the curve (AUC) of the receiver operating characteristic curve was used to calculate the predictive ability of the grading of gastric mucosal atrophy under endoscopy in high-risk histological staging. Furthermore, multivariate logistic regression analysis was used to assess factors influencing the consistency of the 2 evaluation systems. Chi-square test or Fisher′s exact test were used for statistical analysis. Results:Longitudinal follow-up was completed in 97 cases, with a follow-up time of (37.38±13.18) months after H. pylori eradication. The proportion of OLGA stage Ⅲ to Ⅳ in patients with no or mild atrophy (21.7%, 10/46) was lower than that in patients with moderate and severe atrophy (63.0%, 29/46 and 5/5, respectively), and the differences were statistically significant( χ2=16.07 and 13.30, both P<0.001). However, there was no significant difference in distribution of OLGA staging between patients with moderate atrophy and patients with severe atrophy (all P>0.05). The consistency rate of high-risk assessment for gastric cancer between the 2 evaluation systems was 73.2% (71/97). The correlation between the Kimura-Takemoto classification and OLGA staging was moderate ( r=0.47, 95% confidence interval(95% CI) 0.30 to 0.61, P<0.001). The result of consistency test indicated that the consistency of the 2 evaluation systems was moderate, and the Kappa value was 0.46 (95% CI 0.29 to 0.64, P<0.001). For patients with chronic gastritis after H. pylori eradication, the sensitivity of Kimura-Takemoto classification of moderate to severe atrophy under endoscopy in identifying high-risk of OLGA stages was 77.21% (95% CI 62.16% to 88.53%), the specificity was 69.81% (95% CI 55.66% to 81.66%), and the AUC was 0.735 (95% CI 0.636 to 0.820, P<0.01). As the time after H. pylori eradication increased (post- H. pylori eradication less than 18, 18 to 36, and more than 36 months), the consistency of atrophy assessment between the Kimura-Takemoto classification and OLGA staging reduced (7/8, 84.4% (27/32), 64.9% (37/57), respectively), and the difference was statistically significant ( χ2=4.36, P=0.037). The result of multivariate logistic regression analysis revealed that the time after H. pylori eradication more than 36 months ( OR=3.443, 95% CI 1.117 to 10.614, P=0.031) and gastric ulcer ( OR=3.928, 95% CI 1.177 to 13.110, P=0.026) were independent factors influencing the consistency between the Kimura-Takemoto classification and OLGA staging. Conclusions:The endoscopic and histological changes of chronic gastritis after eradication of H. pylori are consistent. Within short period after H. pylori eradication (no more than 36 months), the sensitivity of high-risk classification under endoscopy is high and the specificity is moderate, which can predict high-risk histological staging to a certain degree.

OBJECTIVE To investigate the protective effect of Tibetan medicine Sanguo decoction on hyperlipidemic rats based on the Nrf2/HO-1 signaling pathway and its related mechanisms. METHODS Forty-eight male SD rats were randomly divided into six groups: the normal control group, the model control group, the simvastatin group(3.5 mg·kg−1), and the Tibetan medicine Sanguo decoction low, medium, and high dose groups(0.43 , 0.86 , 1.72 g·kg−1), with eight rats in each group. The normal control group was fed a basal diet, and the remaining groups were fed the H10060 high-fat diet to prepare a hyperlipidemic rat model. At the same time, each treatment group was given corresponding drugs by gavage once a day. The normal control group and model control group were given an equal volume of physiological saline(once a day) by gavage for 6 consecutive weeks. After 6 weeks, serum levels of lipids[totalcholesterol(TC), triglyceride(TG), low density lipoprotein(LDL) and high density lipoprotein(HDL)] and oxidative parameters[malondialdehyde(MDA), superoxide dismutase(SOD), and glutathione(GSH)] were measured by reagent kit. Nuclear factor erythroid 2-related factor 2(Nrf2), heme oxygenase 1(HO-1), Keap1, and quinone oxidoreductase(NQO1) protein expression in liver tissues were analyzed by Western blotting. The correlation of lipid and oxidative indices was investigated by person correlation. RESULTS Compared with the normal control group, the model control group showed a significant increase in body weight, significantly higher serum levels of TC, TG, LDL, and MDA, significantly lower serum levels of HDL, and significantly lower SOD and GSH activity. Compared with the model control group, each administration group showed a decrease in body weight and serum TC, TG, LDL, and MDA levels. In comparison with the model control group, the body weight was reduced, the serum levels of TC, TG, LDL, and MDA were significantly lower, the serum levels of HDL were significantly higher, and the SOD and GSH activities were significantly higher. Keap1 protein level expression was significantly up-regulated compared with the normal control group, and Nrf2, HO-1, and NQO1 protein level expression were significantly down-regulated in the model control group. Keap1 protein level expression was significantly down-regulated compared to the model control group, and Nrf2, HO-1, and NQO1 protein level expression were significantly up-regulated in the liver tissues of low and high doses of Sanguo decoction. The expressions of Nrf2, HO-1, and NQO1 were significantly up-regulated. Correlation analysis showed that TG was negatively correlated with SOD, HO-1, and NQO1, and positively correlated with Keap1, while TC was negatively correlated with SOD, HO-1, GSH, and Nrf2, and positively correlated with Keap1 and MDA. CONCLUSION The Tibetan medicine Sanguo decoction can improve body weight and blood lipid levels in hyperlipidemic rats, and the mechanism may be related to the regulation of the Nrf2/HO-1 signaling pathway and the improvement of oxidative stress.
