OBJECTIVES: To compare the anti-inflammatory, antibacterial and analgesic effects of Yinqiao Powder (YQS) formulated granules and decoction. METHODS: We first evaluated the anti-inflammatory effects of the two dosage forms of YQS in a LPS-induced RAW 264.7 cell model using RT-qPCR and Western blotting. We further constructed zebrafish models of inflammation by copper sulfate exposure, caudal fin transection, or LPS and Poly (I:C) microinjection, and evaluated anti-inflammatory effects of YQS granules and decoction by examining neutrophil aggregation and HE staining findings. In a mouse model of acute lung injury (ALI) induced by intratracheal LPS instillation, the effects of YQS gavage at 10, 15, and 20 g/kg on lung pathologies were evaluated by calculating lung wet-dry weight ratio and using HE staining, ELISA and Western blotting. The microbroth dilution method was used to evaluate the antibacterial effect of YQS. Mouse pain models established by hot plate and intraperitoneal injection of glacial acetic acid were used to evaluate the analgesic effects of YQS at 10, 15, and 20 g/kg. RESULTS: Both YQS granules and decoction significantly reduced TNF-α, IL-6, and IL-1β expressions and p-STAT3 (Tyr 705) phosphorylation level in LPS-induced RAW 264.7 cells, and obviously inhibited neutrophil aggregation in the zebrafish models. In ALI mice, YQS granules and decoction effectively ameliorated lung injury, lowered lung wet-dry weight ratio, and reduced p-STAT3 (Tyr 705) expression and TNF-α and IL-6 levels. YQS produced obvious antibacterial effect at the doses of 15.63 and 31.25 mg/mL, and significantly reduced body torsion and increased pain threshold in the mouse pain models. CONCLUSIONS The two dosage forms of TQS have similar anti-inflammatory, antibacterial and analgesic effects with only differences in their inhibitory effect on TNF-α, IL-6 and IL-1β mRNA expressions in LPS-induced RAW 264.7 cells.

Objective:To analyze the clinical features of pachydermoperiostosis (PDP) and improve its diagnostic level.Methods:A retrospective analysis was conducted on the clinical data of four patients with PDP treated at Sun Yat-sen Memorial Hospital, Sun Yat-sen University from 2015 to 2023, including clinical manifestations, laboratory tests, imaging examinations, and genetic testing results.Results:All four patients were male with an average onset age of 15 years old (ranging from 9 to 18 years old). One patient′s uncle had PDP, and another patient′s parents were consanguineous, though neither parent showed signs of PDP. All four patients exhibited clubbing, skin thickening, and acne; three had frontal bossing and deepened nasolabial folds; two showed scalp sulci changes on head MRI, and all had periosteal thickening of the phalanges visible on X-ray. One patient accompanied with hypokalemic nephropathy, and another had gastric ulcer. One patient underwent whole exome sequencing test which revealed a homozygous mutation, SLCO2A1 gene c.1406C>T, leading to a protein change p.Pro469Leu. Computational tools REVEL, SIFT, and Polyphen2 predicted this variant as deleterious.Conclusion:In addition to skin thickening, frontal bossing, scalp sulci changes, clubbing, and periosteal proliferation, patients with PDP may also present with hypokalemic nephropathy and gastric ulcer. The SLCO2A1 gene c.1406C>T mutation may be pathogenic.

Objective:To assess the efficacy and safety of “one-stop” procedures combining radiofrequency catheter ablation and left atrial appendage closure by guidance of intracardiac echocardiography(ICE) in elderly patients with atrial fibrillation.Methods:A retrospective cohort study was conducted on patients who underwent ICE-guided “one-stop” procedures at the Department of Cardiology, General Hospital of Northern Theater Command between December 2020 and January 2023. Patients were divided into elderly group (age≥60 years old) and non-elderly group (age 18-59 years old). The clinical characteristics, acute success rate, peri-operative complications and follow-up data between two groups were compared. Multivariate logistic regression analysis was used to analyze whether age was the influencing factor for perioperative complications and atrial fibrillation recurrence.Results:A total of 213 atrial fibrillation patients were enrolled, including 158 (74.18%) in the elderly group (age: (68.3±5.0) years; 56.96% male) and 55 (25.82%) in the non-elderly group (age: (53.7±5.2) years; 81.82% male). The elderly group had lower proportions of males, persistent atrial fibrillation, and left atrial spontaneous echocardiographic contrast compared to the non-elderly group ( P<0.05). CHA 2DS 2-VASc and HAS-BLED scores were higher in elderly group ( P<0.05). The acute success rate,“one-stop” procedure time, fluoroscopy time and the rate of peri-operative complications (6 (3.80%) in elderly group vs. 2 (3.64%) in non-elderly group) were similar between two groups (all P>0.05). The average time of clinical and telephone interviews in elderly group and non-elderly group was (16.9±6.1) months and (17.9±5.9) months, respectively. There was no significant difference in the rate of atrial fibrillation recurrence or clinical events between two groups (47 (30.72%) vs. 14 (26.42%), P=0.554; 10 (6.54%) vs. 2(3.77%), P=0.689, respectively). Iatrogenic atrial septal defects in 3-month transesophageal echocardiography follow up were detected in 44 patients (36.97%) in elderly group and 9 patients (19.57%) in non-elderly group ( P=0.032). Multivariate logistic regression analysis results showed that age was not the influencing factor for peri-operative complications and atrial fibrillation recurrence ( P=0.905 and P=0.676, respectively). Conclusion:Intracardiac echocardiography-guided “one-stop” procedures in the treatment of atrial fibrillation in elderly patients are safe and effective.

Objective:To investigate the efficacy and safety of ablation index-guided radiofrequency catheter ablation (RFCA) and second-generation cryoballoon ablation (CBA) in elderly patients with atrial fibrillation (AF).Methods:This retrospective cohort study included 1 986 patients undergoing pulmonary vein isolation for AF at General Hospital of Northern Theater Command from August 2016 to May 2020, comprising 760 RFCA cases and 1 226 CBA cases. Elderly patients were defined as those aged 60 years or older, while non-elderly patients were those under 60 years of age. All patients were followed up for 3 years after the procedure to assess AF recurrence rates. Kaplan-Meier survival curves were plotted and compared by log-rank test. Multivariate logistic regression was used to analyze the influencing factors of AF recurrence.Results:Among 1 986 AF patients (aged (58.7±10.2) years; 1 307 males, 65.81%; 987 elderly patients, 49.70%), the overall AF recurrence rate was 24.37% (484/1 986). Kaplan-Meier analysis demonstrated a higher AF recurrence rate in the elderly group compared to the non-elderly group (log-rank P=0.007). In the RFCA group, AF recurrence rate was 22.50% (171/760), with no significant difference between the elderly (24.44%, 88/360) and non-elderly (20.75%, 83/400) subgroups ( P=0.223). In the CBA group, recurrence rates were 25.53% (313/1 226), with significantly higher recurrence in elderly patients (28.55%, 179/627) than non-elderly (22.37%, 134/599) ( P=0.013). Multivariate logistic regression analysis revealed that advanced age was not an independent predictor of AF recurrence ( P=0.447). Longer AF duration and larger left atrial diameter were independent risk factors for recurrence, while male sex was a protective factor (all P<0.05). Conclusion:Pulmonary vein isolation with second-generation CBA and RFCA guided by ablation index are safe and effective in the treatment of AF in elderly patients.

Objective To investigate the clinical characteristics,distribution of traditional Chinese medicine(TCM)syndrome types,and the anxiety and depression status in patients with colorectal polyps.Methods From January 2022 to December 2023,a total of 200 cases of patients with colorectal polyps(polyp group)and 100 patients without intestinal abnormalities(non-polyp group)under colonoscope who received colonoscopy or treatment at the Endoscopy Center of Dongguan Hospital,Guangzhou University of Chinese Medicine were enrolled.The relevant medical information of the patients in the two groups were collected,and then TCM syndrome differentiation of patients with colorectal polyps were carried out,the general infromation including gender,age,body mass index(BMI),smoking history and alcohol-intake history was recorded,and Hospital Anxiety and Depression Scale(HAD)score was calculated for assessing their anxiety and depression status.Results(1)The investigation of clinical characteristics showed that between the polyp group and the non-polyp group,the differences in the general information of gender,age,BMI,smoking history and alcohol-intake history were statistically significant(P<0.05 or P<0.01).As for the gender,the polyp group was predominated by the male(63.5%),while the non-polyp group was predominated by the female(58.0%),indicating that male patients were more likely to suffer from colorectal polyps.In terms of the age,the age group of 51-60 years old accounted for a higher percentage(36.0%)in the polyp group,while the age group of 41-50 years old accounted for a higher percentage(38.0%)in the non-polyp group,indicating that the polyp group had an elder average age than the non-polyp group.In addition,the percentages of patients with obesity(BMI≥28.0 kg/m2),smoking history,and alcohol-intake history in the polyp group were higher than those in the non-polyp group.(2)The analysis of features of colorectal polyps showed that the polyps were mostly seen in the left colon,accounting for 53.5%in the polyp group;adenomatous polyps accounted for 57.0%of all polyps;the size of colorectal polyps was usually less than one centimeter,accounting for 81.5%of all polyps;single colorectal polyps accounted for 45.5%,and multiple colorectal polyps accounted for 54.5%,indicating that colorectal polyps were usually multiple.(3)Among the 200 patients with colorectal polyps,there were 93 cases of syndrome of stagnation dampness due to spleen deficiency(46.5%),59 cases of dampness-heat in large intestine syndrome(29.5%),27 cases of liver depression and qi stagnation syndrome(13.5%),and 21 cases of dampness and blood stasis obstruction syndrome(10.5%).There were no statistically significant differences in the distribution of TCM syndrome types among colorectal polyp patients with different genders,ages,BMIs and alcohol consumption(P>0.05).The difference in the distribution of TCM syndrome types among colorectal polyp patients with or without smoking history was statistically significant(P<0.05).No statistically significant differences were shown in the distribution of TCM syndrome types among the colorectal polyp patients with various foci,number of polyps,and pathological types(P>0.05).The difference in the distribution of TCM syndrome types in colorectal polyp patients with different polyp sizes was statistically significant(P<0.05).In the patients with the polyp size0.05).In addition,the differences of anxiety scores and depression scores in the patients with various TCM syndrome types were not statistically significant(P>0.05).Conclusion(1)The distribution of TCM syndrome types of colorectal polyps is predominated by the syndrome of stagnation dampness due to spleen deficiency and dampness-heat in large intestine syndrome.The distribution of TCM syndrome types has no correlation with anxiety and depression,and the polyp foci,number of polyps,and pathological types of polyps,but has certain correlation with the size of the polyps.(2)Anxiety and depression may be the risk factors for colorectal polyps,but the polyp foci,number of polyps,and pathological types of polyps have no correlation with anxiety and depression,and the size of polyps may have certain correlation with anxiety.(3)Gender,age,smoking history and alcohol-intake history may be the risk factors for colorectal polyps.
