Objective: There is controversy among different guidelines regarding the use of thermal ablation to treat clinical T1a renal cell carcinomas with tumor sizes ranging from 3.1–4 cm. Therefore, we compared oncological outcomes between heat-based thermal ablation (hTA) and cryoablation (CA) in patients with solid T1a renal cell carcinomas, including those with a tumor size ≤3 cm and a tumor size of 3.1–4 cm. Materials and Methods: Within the Surveillance, Epidemiology, and End Results database (2000–2019), we identified patients with clinical T1a renal cell carcinomas that were histologically confirmed and treated with hTA or CA. After propensity score matching using a 1:1 ratio, the overall survival (OS) and cancer-specific survival (CSS) were estimated and compared between the two methods. Cancer-specific mortality (CSM) was also analyzed, considering other-cause mortality as a competing risk. Results: Of the 3513 assessable patients, 1426 (40.6%) and 2087 (59.4%) were treated with hTA and CA, respectively. After propensity score matching, the hTA and CA groups included 1393 and 1393 patients, respectively. hTA was associated with shorter OS than CA with a hazard ratio of 1.17 (95% confidence interval, 1.04–1.32; P = 0.010). The hTA and CA groups did not reveal statistically significant differences in CSS with a hazard ratio of 1.07 (95% confidence interval, 0.76–1.50; P = 0.706). The hTA and CA groups did not show statistically significant differences in CSM (P = 0.849). However, the hTA group showed a significantly higher other-cause mortality (P = 0.011). Conclusion In patients with clinical stage T1a renal cell carcinomas, hTA was comparable to CA in terms of CSS and CSM.However, hTA resulted in a slightly shorter OS than CA. Large-scale randomized clinical trials are required to obtain more robust evidence.

OBJECTIVE: To evaluate the effectiveness and safety of Rotarex catheter system in treating femoropopliteal artery stenosis accompanied with thrombosis. METHODS: From Jun. 2017 to Dec. 2019, the clinical data of 32 femoropopliteal artery stenosis accompanied with thrombosis cases treated with Rotarex catheter system were retrospectively analyzed. There were 23 males and 9 females aged from 50 to 89 years and the mean age was (70.7±10.3) years. Six cases had acute course of disease (≤2 weeks), 17 cases had subacute course of disease (>2 weeks, ≤3 months), and 9 cases had chronic course of disease (>3 months). Mean lesion length was (23.4±13.7) cm, mean occlusion length was (19.9±13.3) cm, and in-stent occlusion 7 cases. The superficial femoral artery (SFA) was involved in 13 cases, the popliteal artery (PA) was involved in 8 cases, and both SFA and PA were involved in the other 11 cases. All the cases were treated with Rotarex catheter system. When necessary, suction with large lumen catheter was enabled. Residual stenosis was treated with percutaneous transluminal angioplasty (PTA). Drug-coated balloon (DCB) was only used in patients with financial status, and stent was used only when it was necessary. Heparin was used for 24 h after procedures, and after that, antiplatelet agents were used. Doppler ultrasonography was taken during the followed-up. RESULTS: Technical success was 100%, and mean procedure time was (107.4±21.5) min. 8F (1F≈0.33 mm) and 6F Rotarex catheter were used in 27 and 5 cases respectively. In 27 cases, forward flow was obtained immediately after debulking with Rotarex catheter, and in the other 5 cases, suction with large lumen catheters were used. PTA was used in all 32 cases. DCB were used in 8 cases, of which 4 were used in in-stent stenosis. Twelve cases were implanted stents. There were no perioperative deaths. The only one procedure related complication was distal embolism. We took out the thrombus with guiding catheter. In all cases, mean hospital stay were (4.6±1.5) d. The ankle brachial index increased from 0.32±0.15 to 0.86±0.10 after treatment (t=-16.847, P < 0.001). The Rutherford stages decreased significantly (Z=-4.518, P < 0.001). All the patients were followed up for 6.0-36.0 months, and the median time was 16.0 months. 2 cases stopped antiplatelet agents, which resulted in acute thrombosis. Another percutaneous mechanical thrombectomy and PTA were taken in one of them. Two cases died of cardiovascular disease during the follow-up, and no amputation was observed. Target lesion restenosis occurred in 7 cases during the follow-up, and target lesion revascularization (TLR) was taken in two of them. CONCLUSION In treating femoropopliteal artery stenosis accompanied with thrombosis, Rotarex catheter can remove thrombus effectively, and that can expose underlying lesions and reduce stent use and complications rates. It is a safe and effective method.

ObjectiveTo explore the role of microRNA-99b-5p （miR-99b-5p） in cardiomyocyte hypertrophy and the related mechanism involved. MethodsThe expression of miR-99b-5p in myocardium was detected by real-time quantitative PCR（RT-qPCR）in the myocardium of patients with heart failure（HF）and healthy controls， as well as in the myocardium of mouse model of transverse aortic restriction （TAC）-induced cardiac hypertrophy. Phalloidin-iFluor 647 staining was used to show the size of neonatal mouse ventricular cardiomyocytes（NMVCs）after AngⅡ treatment. MiR-99b-5p expression was determined by RT-qPCR in AngⅡ-treated NMVCs. After transfection with miR-99b-5p mimic， the expression of cardiac hypertrophy-associated genes and Fgf21 in NMVCs was detected by RT-qPCR and Western blot assay， respectively. We identified the interaction between miR-99b-5p and the 3’UTR of Fgf21 mRNA by dual luciferase reporter assay. The recombinant Ffg21 adenovirus（rAd-Fgf21）and rAd-Sod2 were used to infect NMVCs， and the expression of β-MHC， ANP， FGF21 and SOD2 was detected by Western blot assay. We knocked down Fgf21 and Sod2 in NMVCs to investigate the role of FGF21/Sod2 axis in miR-99b-5p-regulated NMVC hypertrophy. ResultsMiR-99b-5p expression was elevated in the myocardium of HF patients and TAC-operated mice， and in AngⅡ-treated NMVCs （P＜0.01， respectively）. MiR-99b-5p promoted the expression of hypertrophy-related genes in NMVCs （P＜0.01）. Results of dual luciferase reporter gene assay revealed the interaction between miR-99b-5p and Fgf21 mRNA. MiR-99b-5p down-regulated the expression of Fgf21 and the down-stream gene of Sod2（ P＜0.01）. Overexpression of FGF21 or SOD2 could inhibit NMVC hypertrophy and effectively reversed the pro-hypertrophy effect of miR-99b-5p on NMVCs （P＜0.05， respectively）. ConclusionMiR-99b-5p is up-regulated in the hypertrophic myocardium and enhances cardiomyocyte hypertrophy via suppressing Fgf21/Sod2 axis.

A new rapid, quality control method based on quantitative water tests has been established for the quality evaluation of Indigo Naturalis. The Turbiscan stability index (TSI) of 26 batches of Indigo Naturalis was measured by a stability analyzer. The parameters, including the method by which the ingredients are added, their particle size, amount, and the testing temperature, were systematically optimized and the methodological indexes such as repeatability and stability were determined. The content of indigo and indirubin in 26 batches of Indigo Naturalis was determined by high performance liquid chromatography and the total ash was measured. The correlation analysis between the active ingredients, total ash content and TSI value of Indigo Naturalis was determined by SPSS 26.0 and Origin 2021. This research shows that the best way to prepare samples for testing is to add 0.2 g of Indigo Naturalis powder which has passed through a No. 7 sieve but failed to pass through a No. 9 sieve to a glass bottle containing 20 mL pure water by a funnel and scan at 25 ℃ with a stability analyzer. Consistency analysis showed that the content ranking of indigo and indirubin is opposite to the TSI value, and the content ranking of total ash is generally consistent with the TSI value. Correlation analysis showed that the correlation coefficients of indigo and indirubin content and TSI value were -0.850 and -0.801, respectively, and R² was 0.72 and 0.64. The correlation coefficient between total ash content and TSI value was 0.724, R² was 0.52. Using the change in TSI value of Indigo Naturalis powder in water, this study establishes the range of classification of Indigo Naturalis decoction pieces and the content of relevant components, which can be used to authenticate Indigo Naturalis and evaluate its quality.

Galli Gigerii Endothelium Corneum (GGEC) is a commonly used traditional Chinese medicine for digestion. Its odor is unpleasant, which decreases children's compliance with taking this traditional medicine. Traditional processing methods utilize heat processing methods such as stir-frying and vinegar processing to deodorize the medicine, but this affects the activity of digestive enzymes, so there is a need to find a new method for removing the fishy odor while retaining the beneficial effect of GGEC. Here we have developed the use of supercritical CO₂ low-temperature fluid extraction to eliminate the odor while retaining the medicinal benefits. Headspace-solid-phase microextraction-gas chromatography-triple quadrupole mass spectrometry (HS-SPME/GC-QQQ-MS/MS) combined with the gas activity value method was used to determine compositional differences in the product before and after supercritical CO₂ extraction and separation. Then, based on the sensory evaluation of volunteers, combined with the analysis of volatile components, the fishy odor intensity and the types of fishy odorants were compared between the raw product, stir-fried product, vinegar product and the supercritical CO₂ extract. Pepsin and amylase activity were used to compare the differences in the digestive enzyme activities with the four forms of GGEC, and Fourier transform infrared spectroscopy (FT-IR) was used to compare the differences in the structure. We compared the content of total amino acids, digestive amino acids and bitter amino acids, and an animal model of delayed gastric emptying in mice with soybean oil, based on a phenol red indicator, was used to determine differences in the efficacy of gastric emptying in vivo. The results show that the fishy odor of GGEC powder is significantly reduced after supercritical extraction, and the substances that contribute the fishy odor are only 12.8% of the raw material. The results of FT-IR analysis show that the supercritical extract of GGEC is not changed in its material structure compared with the raw product. The digestive enzyme activity titers showed that amylase and pepsin activity in the raw products are about 3.9 and 1.4 times higher than those of stir-fried products and vinegar products. The activity titers of amylase and pepsin in the supercritical CO₂ extracts are about 2.7 and 1.3 times higher than those of stir-fried products and vinegar products, and there was no significant difference in the content of digestive-promoting amino acids in the four types of GGEC. The in vivo validation experiment showed that the average gastric emptying rates of the mice in the raw product group, the supercritical extract group, the stir-fried product group, and the vinegar product group were 69%, 59%, 40% and 51%, respectively. Compared with the stir-frying method and the vinegar-simmering method, the supercritical CO₂ fluid extraction method retained the gastric emptying effect of GGEC. In general, the supercritical CO₂ fluid low-temperature extraction method removes the fishy odor of GGEC as compared with the traditional stir-frying method and vinegar method, and retains the biologically active components and the effect on digestion of GGEC.

Objective:To analyze the relationship between the high sensitivity C-reactive protein (hs-CRP) and anxiety levels in patients hospitalized with cardiovascular-related diseases and hypertension.Methods:A total of 221 patients hospitalized with cardiovascular-related diseases in the Fuwai Hospital were selected by a voluntary sampling method from September to December 2021. Participants were divided into hypertensive and non-hypertensive groups ( n=119 and n=102) based on the diagnosis of hypertension in their inpatient medical records. Anxiety levels were assessed using the Zung Self-Rating Anxiety Scale, and the levels of serum hs-CRP were estimated by automatic immunoanalyzer. Multivariate logistic regression was used to analyze the relationship between hs-CRP and anxiety. Results:In the hypertensive group, the risk of anxiety in patients with abnormal hs-CRP (>3 mg/L) was 4.239 times (95% CI: 1.569-11.748, P=0.005) higher than those in normal hs-CRP (≤3 mg/L). In turn, compared with patients without anxiety, those with anxiety had 3.878 times greater probability of experiencing abnormal hs-CRP (95% CI: 1.495-10.062, P=0.005), while those with mild anxiety and moderate to severe anxiety had 4.525 times (95% CI: 1.392-14.714, P=0.012) and 3.286 times (95% CI: 0.911-11.357, P=0.070) greater odds of experiencing abnormal hs-CRP, respectively. No similar significant association was seen in the non-hypertensive group. Conclusion:There is an interrelationship between elevated hs-CRP and anxiety in hospitalized patients with cardiovascular-related diseases and hypertension.
