OBJECTIVE To analyze the differences in chemical components of Gardenia jasminoides before and after processing with ginger， and to evaluate the quality differences among different producing areas. METHODS Ultra-high performance liquid chromatography-tandem time-of-flight mass spectrometry was used to analyze the compositional differences of G. jasminoides before and after processing with ginger. The water content， total ash， and ethanol-soluble extract content of ginger- processed G. jasminoides were determined according to the 2020 edition of Chinese Pharmacopoeia. High performance liquid chromatography was adopted to determine the contents of genipin gentiobioside， geniposide， crocin Ⅰ and crocin Ⅱ in ginger- processed G. jasminoides. RESULTS A total of 49 chemical components were identified from raw G. jasminoides and ginger- processed G. jasminoides， including 14 flavonoids， 15 iridoids， 10 organic acids， 2 alkaloids and 8 other compounds. Among them， 42 components were detected in raw G. jasminoides， 28 in ginger-processed G. jasminoides， and 21 components were common to both. After processing with ginger， raw G. jasminoides lost 21 components （including iridoids， flavonoids， alkaloids， and others）， while 7 chemical components were added （including coumarins， organic acids， organic acid esters， and flavonoids）. For the 15 batches of ginger-processed G. jasminoides， the water content ranged from 5.64% to 7.11%， total ash from 2.92% to 4.87%， and ethanol-soluble extract from 40.61% to 58.02%. The average contents of genipin gentiobioside， geniposide， crocin Ⅰ and crocin Ⅱ were 0.108 7， 0.542 2， 0.565 0， and 0.012 5 mg/g， respectively. CONCLUSIONS After processing with ginger， G. jasminoides loses 21 components， while 7 new components are added. Differences are observed in the water content， total ash， ethanol-soluble extract， and the contents of genipin gentiobioside， geniposide， crocin Ⅰ， and crocin Ⅱ of ginger-processed G. jasminoides from different producing areas. Notably， samples from Fujian exhibit high contents of genipin gentiobioside and ethanol-soluble extract， while samples from Jiangxi have a high content of crocin Ⅰ.

Objective:To explore the differences in resting-state brain functional activity in obsessive-compulsive disorder (OCD) patients with and without sensory phenomena (SP).Methods:Clinical data from 102 OCD patients (60 males, 42 females; age 18-50(27±8) years) who visited the OCD outpatient clinic at the Affiliated Brain Hospital of Nanjing Medical University between August 2021 and December 2022 were prospectively collected. Based on the presence of sensory phenomena, patients were categorized into 70 cases with sensory phenomena (Sensory Phenomena Group) and 32 cases without sensory phenomena (Non-Sensory Phenomena Group). Additionally, 50 age-matched healthy controls (Control Group, 24 males, 26 females; age 18-49(25±6) years) were recruited. Resting-state functional magnetic resonance imaging (rs-fMRI) was analyzed using the amplitude of low-frequency fluctuations (ALFF) and functional connectivity (FC) between differential brain regions. One-way ANOVA and post-hoc tests were used to compare group differences. Spearman correlation and binary logistic stepwise regression were applied to analyze the associations between SP and brain functional activity.Results:Compared to healthy controls, OCD patients showed decreased ALFF in bilateral middle frontal gyri, left superior frontal gyrus, right angular gyrus, and right supramarginal gyrus ( F=17.29-32.99, all P<0.05). The SP group exhibited increased ALFF in the right triangular part of the inferior frontal gyrus ( F=23.47, P<0.05) and decreased ALFF in the left superior parietal gyrus and left postcentral gyrus ( F=18.80, 15.04; both P<0.05). The non-SP group demonstrated increased ALFF in the left supramarginal gyrus and left postcentral gyrus ( F=19.64, 15.04; both P<0.05) and decreased ALFF in the left superior frontal gyrus, right middle frontal gyrus, and left angular gyrus ( F=17.29-35.52, all P<0.05). Reduced FC was observed between the left middle frontal gyrus and left angular gyrus, left middle frontal gyrus and right angular gyrus and left and right angular gyri ( F=17.29-23.47, all P<0.05). The SP group showed lower FC between the left middle frontal and left angular gyrus than the non-SP group ( F=23.47, P<0.05). Positive correlations with SP were found for ALFF in the right triangular part of the inferior frontal gyrus, left superior frontal gyrus, and right middle frontal gyrus (r=0.40, 0.35, 0.31; all P<0.05). Negative correlations were observed for ALFF in the left supramarginal gyrus, left superior parietal gyrus, and left postcentral gyrus (r=-0.38, -0.47, -0.52; all P<0.05) and FC between the left middle frontal gyrus-left angular gyrus and left middle frontal gyrus-right angular gyrus (r=-0.24, -0.21; both P<0.05). OCD patients with increased ALFF in the left superior frontal gyrus and right middle frontal gyrus, along with decreased ALFF in the left supramarginal gyrus, left superior parietal gyrus, left postcentral gyrus, and reduced FC between the left middle frontal gyrus-right angular gyrus, had a higher likelihood of SP (log OR (95% CI)=8.5(4.0-14.2), 8.0(1.7-16.4), -8.9(-15.2--4.4), -5.2 (-9.1--2.3), -4.1(-6.9--1.7), -7.0(-13.2--1.8); all P<0.05). Conclusion:Altered functional activity in the left superior frontal gyrus, right middle frontal gyrus, left supramarginal gyrus, left superior parietal gyrus, left postcentral gyrus, and abnormal FC between the left middle frontal gyrus and right angular gyrus represent key neuroimaging features of OCD patients with SP.

Objective To investigate the therapeutic effects of the newly developed phosphodiesterase 5 inhibitor,CPD1,on pathological myocardial hypertrophy induced by abdominal aortic constriction(AAC)in rats,and its impact on activation of the autophagy signaling pathway in myocardial tissue.Methods Male Sprague Dawley rats weighing 180～200 g were divided randomly into five groups:Control,Sham,model(AAC),CPD1 treatment(AAC-CPD1,5 mg/kg),and sildenafil treatment(AAC-Sif,20 mg/kg)groups.Rats in all groups except the Control group underwent blunt dissection of the abdominal aorta at the branch point of the left renal artery.Rats in the AAC and treatment groups also underwent constriction and ligation surgery,while rats in the Sham group underwent dissection without ligation.After 3 days of modeling,rats in the treatment groups received either CPD1 or sildenafil via gavage,while rats in the Control,Sham,and AAC groups received an equal volume of physiological saline by gavage,once daily for 8 weeks.Small-animal ultra-high-resolution echocardiography and left ventricular catheterization were employed to assess left heart function and the heart mass index,and expression levels of the hypertrophy indicator,atrial natriuretic peptide(ANP),the key autophagy pathway factor,p62,and LC3A/B in rat left heart tissue were evaluated by Western blot and reverse transcription-polymerase chain reaction.Results Abdominal aortic stenosis affected left heart function in rats,characterized by an increased cardiac mass index and significant enlargement of myocardial cell cross-sectional area.ANP expression levels in left heart tissue were significantly elevated(P＜0.05),while autophagy signaling activity was reduced,with notable accumulation of LC3Ⅰprotein and reduced conversion to LC3Ⅱ.Expression levels of p62 protein were significantly increased.CPD1 and sildenafil significantly improved left ventricular function in AAC rats,reduced cardiac hypertrophy,inhibited expression levels of ANP and p62 proteins(P＜0.05),activated autophagy signaling,and promoted the conversion of LC3Ⅰ to LC3Ⅱ.Notably,low-dose CPD1 treatment was equivalent to high-dose sildenafil.Conclusions CPD1 promotes the activation of the autophagy signaling pathway in left heart tissue,inhibits the expression of p62 and ANP,reduces the cross-sectional area of myocardial cells,and improves pathological myocardial hypertrophy and left heart function impairment caused by AAC.CPD1 also has the advantage of a lower effective dose compared with sildenafil,offering a new treatment option for pathological myocardial hypertrophy.
