Objective To establish a RP-HPLC method for determining indigo and indirubin in Baphicacanthus cusia from different producing areas and medicinal parts. Methods The separation was achieved by an Agilent TC-C18 Column (4.6 mm×250 mm, 5 μm) at 25 ℃ using methanol-water (75??25) as mobile phase at a flow rate of 1 mL??min-1.The detection wavelength was 290 nm. Results Indigo had a good linear relationship with peak area at range of 0. 051 3-0.820 8 μg (r=0.999 3).The recovery rate was 99.00% and RSD was 1.30% (n=6).Indirubin had a good linear relationship with peak area at range of 0.049 5-0.792 0 μg (r=0.999 9).The recovery rate was 98.88% and RSD was 1.51% (n=6). Conclusion The contents of the two components are obviously different in Baphicacanthus cusia because of different places or medicinal parts. The proposed method is simple, rapid and reliable. This method for determination of indigo and indirubin in Baphicacanthus cusia by RP-HPLC provides a basis for quality control of Baphicacanthus cusia.

ABSTRACT:Objective To explore the changes of serum cytokine interleukin-17 (IL-17)in patients with chronic hepatitis B of different clinical types and its clinical significance.Methods We selected 30 cases of mild chronic hepatitis B,34 cases of moderate one,29 cases of severe one,38 cases of liver cirrhosis,and 21 cases of acute on chronic liver failure.Another 30 cases over the same period served as the healthy control group.Cytokine IL-1 7 level in peripheral blood was detected in each group,and all the groups except the control group were detected for liver function and HBV-DNA.These related serum markers were detected and the results were statistically analyzed.Results ① IL-17 in the peripheral blood was (8.103±2.061)ng/mL in healthy control group;(25.551 ±7.078)ng/mL,(45.442±18.358)ng/mL and (75.378±19.05)ng/mL in the groups with mild,moderate and severe chronic hepatitis B;and (97.16±17.066)ng/mL in acute on chronic liver failure group.Its levels gradually increased with the severity;and there were significantly different among the five groups and between every two groups (P<0.01).The peripheral blood level of IL-17 was (8.103±2.061)ng/mL in the healthy control group, (34.517±8.905)ng/mL in compensatory cirrhosis group,and (45.615±15.623)ng/mL in the decompensated cirrhosis group.These three groups had pairwise comparison,and the difference between every two groups was significant (P<0 .0 1 ).The peripheral blood level of IL-1 7 in the decompensated cirrhosis group increased compared with that in the compensatory group.③ In the 1 5 2 cases detected,serum IL-1 7 level and serum ALT,AST,TBIL,HBV-DNA levels were positively correlated,and serum PTA had negative correlation with the level of IL-1 7 .④ In the 2 1 cases of acute on chronic liver failure,the peripheral blood level of IL-1 7 did not significantly differ between antigen-e positive and negative groups (P=0.654).⑤ In 21 patients with chronic on acute liver failure,the level of IL-1 7 in peripheral serum and MELD scores showed a positive correlation by Pearson correlation analysis (r=0.533,P=0.013).Conclusion In patients with chronic hepatitis B,the level of IL-17 in peripheral serum increased with disease severity.Moreover,the level of IL-1 7 in peripheral blood may play a role in promoting the progression of cirrhosis and the development of acute on chronic liver failure.

Purpose: This study aimed to explore the role of the long non-coding RNA (lncRNA) RNA component of mitochondrial RNAase P (RMRP) in sepsis-induced acute kidney injury (AKI). Materials and Methods: Venous blood was collected from septic patients and healthy people. C57BL/6 mice who underwent cecal ligation and puncture (CLP) were used as in vivo models of septic AKI. Lipopolysaccharide (LPS)-induced HK-2 cells were employed as in vitro models of AKI. Flow cytometry analysis was conducted to detect cell apoptosis. Enzyme-linked immunosorbent assay and Western blot assays were used to detect levels of pro-inflammatory cytokines. Results: RMRP was upregulated in sera from patients with AKI and in LPS-induced cells. Knockdown of RMRP inhibited cell apoptosis and reduced production of inflammatory factors in LPS-induced cells, as well as alleviated AKI in CLP mice. RMRP facilitated inflammation by activating NACHT, LRR, and PYD domains-containing protein 3 (NLRP3) inflammasome. We found that microRNA 206 (miR-206) binds with and is negatively regulated by RMRP: miR-206 directly targets the 3’ untranslated region of DEAD-box helicase 5 (DDX5) and negatively regulates DDX5 expression. By binding with miR-206, RMRP upregulated DDX5 expression. Rescue assays revealed that overexpression of DDX5 counteracted the effect of RMRP inhibition on cell apoptosis and inflammatory response in LPS-induced cells. Conclusion The lncRNA RMRP contributes to sepsis-induced AKI through upregulation of DDX5 in a miR-206 dependent manner and through activation of NLRP3 inflammasome. This novel discovery may provide a potential strategy for treating AKI.

Objective:To analyze the difference of expression of Wnt protein family member 5a(Wnt5a)in prediabetes and diabetes mellitus and its correlation with immune inflammation in patients with prediabetes.Methods:From November 2020 to Novem-ber 2021,64 patients with prediabetes who treated in Zaozhuang Municipal Hospital were selected as group A,51 patients with diabe-tes were selected as group B,and 50 healthy people who underwent physical examination were selected as group C.The baseline data of 3 groups were collected,level of Wnt5a was determined,expression difference of Wnt5a in prediabetes and diabetes was analyzed,the related indicators of immune inflammation were determined,and the correlation between Wnt5a and immune inflammation in patients with prediabetes was analyzed.Predictive value of Wnt5a for prediabetes and diabetes was analyzed by ROC curve,and its cutoff values were determined for clinical disease prediction.Results:Compared with group B,Wnt5a level,immune inflammatory indexes Th1,Th17,Th22,IFN-γ,IL-17A and IL-22 levels in group A were decreased(P<0.05).Logistic regression analysis showed that fasting blood glucose,Wnt5a,Th1,Th17,Th22,IFN-γ,IL-17A and IL-22 were independent risk factors for the occurrence of prediabetes(P<0.05).Wnt5a was positively correlated with immune inflammation-related indicators Th1,Th17,Th22,IFN-γ,IL-17A and IL-22 in patients with prediabetes(P<0.05).ROC curve showed that AUC values of Wnt5a in predicting prediabetes and diabetes were 0.921 and 0.897,respectively,and the AUC were all>0.7,which indicating that Wnt5a had a higher predictive value for predia-betes and diabetes(P<0.05).Conclusion:There is a certain difference in expression of Wnt5a in prediabetes and diabetes.When level of 42.38 pg/ml≤Wnt5a<62.50 pg/ml,it is prediabetes,and when level of Wnt5a≥62.50 pg/ml,it indicates that the transition from prediabetes to diabetes has occurred,and believed that Wnt5a is related to immune inflammation in prediabetic patients,which may increase the degree of insulin resistance by amplifying local immune inflammation in prediabetic patients and eventually lead to the occurrence of diabetes.

Objective : To evaluate the safety and immunogenicity of a split-virion quadrivalent influenza vaccine. Methods : The healthy people aged three years or over in Wuyang County and Xiping County of Henan Province were divided into the experimental group, control group 1 and control group 2, and were vaccinated with split-virion quadrivalent influenza vaccines, split-virion trivalent influenza vaccines (without B/Victoria) and a split-virion trivalent influenza vaccines (without B/Yamagata) , respectively. The hemagglutination inhibition (HI) antibodies were detected before and after immunization. The incidence rate of adverse events following immunization (AEFI) , HI antibody positive conversion rate, the protection rate of HI antibodies and the growth of geometric mean titer (GMT) were calculated and compared with the standard of Food and Drug Administration (FDA). Results: Totally 2 924 people were recruited, with 975 in the experimental group, 974 in the control group 1 and 975 in control group 2. The incidence rate of AEFI in the experimental group was 11.7%, higher than 7.9% in control group 1 and 8.8% in control group 2 (P < 0.05) during 30 minutes and 8 days after inoculation. The positive conversion rates of HI antibodies of H1N1, H3N2, By and Bv in the experimental group were 78.5%, 53.3%, 78.3% and 62.9%, respectively. The rate differences of the positive conversion rates of HI antibodies of By between the experimental group and control group 2, and of Bv between the experimental group and control group 1 were 42.1% (95%CI: 38.0%-46.2%) and 33.2% (95%CI: 28.9%-37.5%) , with both lower limits of 95%CI more than -0.10. The GMT increase of HI antibodies was more than 2.5 times in the three groups. The protective rates of HI antibodies of H1N1, H3N2, By and Bv in the experimental group were 87.7%, 98.7%, 93.6% and 77.2%, respectively. The protective rates of HI antibodies of By in control group 2 and Bv in control group 1 were 71.1% and 51.0%, both lower than those in the experimental group (P < 0.05). Conclusions After the inoculation of the quadrivalent influenza vaccine, the positive conversion rates (>40%) , protection rates (>70%) and GMT increase (>2.5 times) of HI antibodies of H1N1, H3N2, By and Bv all meet the quality standards of FDA. The safety and immunogenicity of the quadrivalent influenza vaccine are not inferior to those of the trivalent influenza vaccine.

Objective To investigate the prognostic influence factors of Solitaire stent thrombectomy in patients with acute anterior circulation macrovascular occlusion. Methods From March 2015 to March 2017,222 consecutive patients with acute anterior circulation macrovascular occlusion admitted to the Department of Neurosurgery,the 101stHospital of People′s Liberation Army and the Nanjing Jinling Hospital were enrolled retrospectively.They were all confirmed by DSA and were treated with Solitaire stent thrombectomy. According to the modified Rankin Scale(mRS) scores at 90 d after treatment,they were divided into a good prognosis group (0-2,n=120) and a poor prognosis group (3-6,n =102). The baseline data and clinical data of the two groups of patients were analyzed,including the risk factors for cardiocerebrovascular diseases,baseline National Institutes of Health Stroke Scale (NIHSS) score,occlusion sites (internal carotid artery or middle cerebral artery occlusion),collateral compensatory,onset to puncture time, operation time,onset to recanalization median time,recanalization status,preoperative Alberta stroke programme early CT score(ASPECTS),and symptomatic cerebral hemorrhage,and then further multivariate logistic regression analysis was conducted for the prognostic factors of patients. Results (1) The rate of good prognosis was 54.1% (120/222).There were no significant differences in patients′ age,NIHSS at admission,ASPECTS at admission,sex,hypertension,occlusion site,and rate of good collateral branches in both groups(all P<0.05).There were no significant differences in other baseline data (all P >0. 05). (2) Onset to puncture time and onset to successful recanalization median time of the patients in good prognosis group was lower than that of the poor prognosis group (182 [138,230]min vs.236[170,305]min, 237[175,269]min vs.288[223,367]min).The proportion of successful recanalization was higher than that of the poor prognosis group (98.3% [118/120] vs.78.4% [80/102]).The proportion of postoperative symptomatic intracerebral hemorrhage was lower than that of the poor prognosis group (2.5% [3/120] vs.21.6% [22/102]).There was significant difference between the two groups (all P <0.01). There was no significant difference in operative time between the two groups (P >0.05). (3)In the single factor analysis,the parameter of P <0.05 was used as an independent variable,and prognosis was used as a dependent variable,multivariate logistic regression analysis showed that the increased age (OR,1.096,95% CI 1.050-1.144),history of hypertension (OR,8.401,95% CI 2.960-23.845),increased baseline NIHSS score (OR,1.071,95% CI 1.007-1.138),prolonged onset to successful recanalization time (OR,1.019,95% CI 1.003-1.035),symptomatic intracerebral hemorrhage after procedure (OR,18.110,95% CI 4.656-70.434) were all the risk factors for poor prognosis(all P<0.05);higher ASPECTS score at admission(OR,0.641,95% CI 0.451-0.911) and successful recanalization (OR,0.127,95% CI 0.024-0.664) were all the protective factors of good prognosis (all P<0.05). Conclusions Higher ASPECTS at admission and successful recanalization were the protective factors of poor prognosis of Solitaire stent thrombectomy in patients with acute anterior circulation macrovascular occlusion.Increased age,history of hypertension,increased baseline NIHSS score,prolonged onset to successful recanalization time,and symptomatic intracerebral hemorrhage after procedure were the risk factors for poor prognosis of Solitaire stent thrombectomy in patients with acute anterior circulation macrovascular occlusion.

Objective To investigate the correlation between the manual compression on injection point and the incidence of subcutaneous bleeding after subcutaneous injection of low molecular weight heparin(LMWH)in elderly patients with coronary artery disease.Methods A total of 131 elderly patients with coronary artery disease,who received subcutaneous injection of LMWH after percutaneous coronary intervention(PCI)at the Affiliated Nanjing Hospital of Nanjing Medical University of China between January 2019 and December 2021,were enrolled in this study.According to whether the manual compression on the injection point was employed or not after the injection of LMWH,the patients were divided into the study group(n=67)and the control group(n=64).The operation process of subcutaneous injection of LMWH was carried out in accordance with the"Supervision Standard for Nursing Quality of Hypodermic Injection of Low Molecular Weight Heparin"which was included in the norms formulated by authors'hospital.For the patients of the study group,the injection point was manually pressed for 3-5 min after the injection of LMWH,the manually-used force was to press the skin down for 1cm deep.The incidence of subcutaneous bleeding was compared between the two groups.Results In the study group and the control group,the incidence of subcutaneous ecchymosis was 9.0%and 7.8%respectively,the incidence of subcutaneous hard tubercle was 4.5%and 1.6%respectively,the differences between the two groups were not statistically significant(both P＞0.05).The patient's age,gender,abdominal circumference and body mass index(BMI)carried no obvious correlation with the subcutaneous bleeding after LMWH injection(P＞0.05),while a statistically significant correlation existed between the abdominal wall fat thickness and the subcutaneous bleeding(P＜0.05),which could be used as an independent predictor for the occurrence of subcutaneous bleeding after LMWH injection.Conclusion No obvious correlation exists between the manual compression on injection point and the incidence of subcutaneous bleeding in elderly patients with coronary artery disease after subcutaneous injection of LMWH,therefore,no compression manipulation,used as a hemostatic measure,is required after subcutaneous injection of LMWH.The abdominal wall fat thickness is an independent predictor for subcutaneous bleeding after injection of LMWH.Standard operation procedures should be strictly followed so as to avoid the occurrence of subcutaneous bleeding after injection of LMWH.(J Intervent Radiol,2024,32:77-81)

Objective:To evaluate the therapeutic effect of hemopurification on acute chlorfenapyr poisoning according to the blood concentration of chlorfenapyr and to provide experience for clinical treatment.Methods:Two patients who presented to our Emergency Department following an ingestion of chlorfenapyr and then were treated with hemopurification in 2022 were included. The concentrations of chlorfenapyr and its highly toxic metabolite tralopyril were dynamically monitored, and the clinical data of the patients were collected.Results:Case 1 was given hemoperfusion for the first time 13 hours after ingestion. During l hour hemoperfusion, the tralopyril decreased by 28.82%. The concentration increased and exceeded the pre-perfusion level after 2 hours of hemoperfusion. After three times of hemoperfusion, the concentrations of chlorfenapyr and tralopyril were still higher than those before the first time, reaching 248 ng/mL and 1 307 ng/mL respectively. The concentration of chlorfenapyr showed a downward trend after 130 h, and the tralopyril in blood reached the peak 3 164 ng/mL at 130 h and decreased to 2 707 ng/mL at 178 h. In case 2, the blood chlorfenapyr and tralopyril concentration was 392 ng/mL and 7 598 ng/mL respectively 150 hours after ingestion. The blood chlorfenapyr concentration decreased by 37.75% respectively after first hemoperfusion, and the tralopyril concentration decreased by 38.02% respectively. During 85 hours of continuous veno-venous hemodiafiltration (CVVHDF), the concentration of tralopyril was maintained at 4 234~6 410 ng/mL. Case 1 was followed up to 12 days and lost follow-up. Case 2 died and the survival time was 247 hours.Conclusions:Hemoperfusion can scavenge tralopyril, but CVVHDF has poor scavenging ability for tralopyril. And the apparent volume of distribution (Vd) of chlorfenapyr and tralopyril are large. After ingestion, chlorfenapyr spreads to various tissues quickly, and it is easy to accumulate in the adipose tissue. The chlorfenapyr in the tissue slowly is released back to the blood and stays in the blood for a long time. The peak concentration of chlorfenapyr appeared earlier than that of tralopyril. Clinicians should pay attention to the early removal of toxins from the digestive tract.
