Objective To investigate the clinical features of dyskinesia and related risk factors in female patients with Parkinson disease （PD）. Methods A cross-sectional study was conducted among the female patients who met the diagnostic criteria for PD at the outpatient service of PD in Aerospace Center Hospital， and demographic data and clinical data were collected and compared between groups， including levodopa equivalent daily dose （LEDD）， Unified Parkinson’s Disease Rating Scale-Ⅲ（UPDRS-Ⅲ）， UPDRS-Ⅳ， scores of non-motor symptoms （cognition and depression）， presence or absence of dyskinesia， and single levodopa dose （LD） during the onset of dyskinesia. A binary logistic regression analysis was used to investigate the influencing factors for dyskinesia in female patients with PD. Results A total of 146 female PD patients were enrolled， among whom 30 patients had dyskinesia， with an incidence rate of 20.5%. Compared with the non-dyskinesia group in terms of clinical features， the dyskinesia group had a significantly younger age of onset [（54.3±12.5） years vs （62.7±10.0） years， P<0.001]， a significantly longer disease duration [（9.9±3.7） years vs （4.5±3.7） years， P<0.001]， a significantly higher severity of disease [H-Y stage： （2.65±0.58） vs （2.35±0.83）， P=0.03]， a significantly longer duration of LD administration [（7.5±3.2） years vs （3.2±2.6） years， P<0.001]， a significantly higher LEDD [（703.2±203.9） mg vs （442.1±226.3） mg， P<0.001]， and significantly lower body weight [（54.1±8.2） kg vs （60.0±8.7） kg， P=0.001] and BMI [（20.9±3.1） kg/m2 vs （23.4±3.1） kg/m2， P<0.001]. The multivariate logistic regression analysis showed that high BMI （OR=0.770， P=0.005） was a protective factor against dyskinesia in female PD patients， while long disease duration （OR=1.304， P=0.001） and high LEDD （OR=1.003， P=0.012） were risk factors for dyskinesia. Conclusion There is a relatively high incidence rate of dyskinesia in female PD patients， which should be taken seriously in clinical practice， and high BMI is a protective factor， while long disease duration and high LEDD are risk factors for dyskinesia in female PD patients.

Although enteric glial cell (EGC) abnormal activation is reported to be involved in the pathogenesis of Parkinson's disease (PD), and inhibition of EGC gliosis alleviated gut and dopaminergic neuronal dysfunction was verified in our previous study, the potential role of gut microbiota on EGC function in PD still need to be addressed. In the present study, fecal microbiota transplantation revealed that EGC function was regulated by gut microbiota. By employing 16S rRNA and metabolomic analysis, we identified that 3-indolepropionic acid (IPA) was the most affected differential microbial metabolite that regulated EGC gliosis. The protective effects of IPA on PD were validated in rotenone-stimulated EGCs and rotenone (30 mg/kg i.g. for 4 weeks)-induced PD mice, as indicated by decreased inflammation, improved intestinal and brain barrier as well as dopaminergic neuronal function. Mechanistic study showed that IPA targeted pregnane X receptor (PXR) in EGCs, and inhibition of IL-13Rα1 involved cytokine-cytokine receptor interaction pathway, leading to inactivation of downstream JAK1-STAT6 pathway. Our data not only provided evidence that EGC gliosis was critical in spreading intestinal damage to brain, but also highlighted the potential role of microbial metabolite IPA in alleviating PD pathological damages through gut-brain axis.

Palmitoylation, an essential covalent attachment of a fatty acid (usually C16 palmitate) to cysteine residues within proteins, is crucial for regulating protein functionality and enzymatic activities. This lipid modification facilitates the anchoring of proteins to cellular membranes, dictating their subcellular distribution and influencing protein transport dynamics and intracellular positioning. Additionally, it plays a role in regulating protein degradation through the ubiquitin-proteasome system. Palmitoylation is implicated in the pathogenesis and progression of cardiovascular diseases by modulating substrates and prompting additional post-translational modifications, as well as by interacting with other molecular alterations. Moreover, an intervention strategy focusing on palmitoylation processes is anticipated to offer novel therapeutic avenues for cardiovascular pathologies and address extant challenges in clinical settings. This review consolidates current research on the role and importance of palmitoylation in cardiovascular diseases by exploring its regulatory functions, the catalyzing enzymes, and the involved substrates. It highlights recent discoveries connecting palmitoylation-targeted therapies to cardiovascular health and examines potential approaches and future challenges in cardiovascular treatment.

Objective To analysis the efficacy and safety of antiviral therapy in patients with chronic hepatitis B virus in indeterminate phase based on the new guidelines(2022 Edition of the Guidelines for the Prevention and Treatment of Chronic Hepatitis B).Methods A total of 170 patients with newly diagnosed HBV infection who visited the Third People's Hospital of Kunming from August 1,2020,to July 31,2024,were selected as study subjects.The clinical indicators of patients with normal ALT in the indeterminate phase were analyzed after 12 weeks,24 weeks,and 48 weeks of antiviral treatment,as well as those who did not receive antiviral treatment for 48 weeks.Results(1)Among the 170 patients with normal ALT during the indeterminate phase of HBV infection,the treatment group consisted of 125 patients(36 HBeAg positive and 89 HBeAg negative),while the untreated group had 45 patients.In the treatment group,the HBV-DNA load and HBsAg titer decreased significantly after 48 weeks compared to before treatment,with statistically significant differences(both P<0.05).In the untreated group,the HBV-DNA load showed an upward trend,and the HBsAg titer slightly decreased,with statistically significant differences(both P<0.05).(2)The CVR rate in the treatment group after 48 weeks was 66.67%(24/36)for HBeAg positive patients and 95.51%(85/89)for HBeAg negative patients,with a statistically significant difference(P<0.05).(3)The treatment group showed a significant decrease in GGT and AFP after 48 weeks compared to before treatment,while the untreated group saw an increase in ALT,GGT,and AFP,with statistically significant differences(all P<0.05).(4)The fibrosis indicators APRI,FIB-4,and LSM in the treatment group significantly decreased after 48 weeks compared to before treatment,with statistically significant differences(all P<0.05).(5)The safety indicators CREA,blood calcium,and blood phosphorus in the treatment group significantly decreased after 48 weeks compared to before treatment,with statistically significant differences(all P<0.05).Conclusion Expanding the antiviral treatment indications according to the new guidelines for patients with normal ALT in the indeterminate phase of HBV infection demonstrates good efficacy in controlling HBV-DNA,improving CVR rates,and enhancing fibrosis indicators,while also showing favorable renal safety.However,there may be a risk of osteoporosis due to calcium and phosphorus metabolism disorders,necessitating enhanced monitoring and prevention.

Objective To use analytic hierarchy process(AHP)-entropy weight method to evaluate the quality of symbiotic Armillaria in Gastrodia elata Bl.Methods The physiological,growth and chemical indexes of 6 strains of G.elata symbiotic Armillaria were used as evaluation factors,and the weight coefficients of each index were calculated by the AHP-entropy weight method.A comprehensive quality evaluation system was established to evaluate the quality of Armillaria strains,and the results were verified by red G.elata and hybrid G.elata combined planting experiments.Results The quality evaluation results showed that extracellular xylanase activity,extracellular cellulase activity and total sugar weight were relatively high,among which strains N6 and N3 ranked the top.The results showed that strains N5 and N4 combined with red G.elata had better quality,that strains N6 and N3 combined with hybrid G.elata had better quality.Conclusion The correlation of extracellular xylanase activity and total sugar of cellulase activity should be paid attention to in the quality evaluation of symbiotic Armillaria in G.elata.The quality evaluation system constructed in this artilcle is basically consistent with the results of hybrid G.elata combined with hybrid G.elata experiment,which can provide references for the quality screening of symbiotic Armillaria in G.elata.

Objective:To investigate the correlation between pen-holding posture, grip strength and myopia.Methods:A cross-sectional study was performed.A total of 496 school-aged children in grades 1-6, who underwent eye examinations at Shenzhen Eye Hospital from November 2021 to May 2022 were consecutively enrolled as subjects.The subjects' age, grade, sex, refractive error and age of school enrollment were recorded.Subjects' grip strength and pen-holding posture were obtained with an electronic grip strength meter and a tool pen, and subjects were divided into correct pen-holding posture group and incorrect pen-holding posture group according to their pen-holding posture.Propensity scores for sex, grade, age at school entry, and grip strength in the two groups were matched using the nearest neighbor matching method.Multifactorial binary logistic regression analysis was performed with binocular myopia, monocular myopia, and emmetropia as dependent variables and grip strength, grade, refractive error, and pen-holding posture as independent variables.The correlation between grip strength and spherical equivalent was examined by Spearman rank correlation analysis and partial correlation analysis.This study protocol adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Shenzhen Eye Hospital (No.2022KYPJ032).Results:After matching propensity scores, there were 101 cases and 197 cases in the correct pen-holding posture group and incorrect pen-holding posture group, respectively.There was no statistical significance in sex, grade, age at enrollment, and grip strength between the two groups (all at P>0.05).Multinomial logistic regression results showed that using emmetropia as a reference, higher grade (4 versus 1∶7.601[1.307-44.206]; 5 versus 1∶4.392[1.039-18.562]), presence of anisometropia (21.366[5.750-79.397]) were relative risk factors for monocular myopia (all at P<0.05), and higher grade (3 versus 1∶4.389[1.783-10.800]); 4 versus 1∶15.398[3.267-72.574]; 5 versus 1∶7.447[2.232-24.851]; 6 versus 1∶6.462[2.116-19.734]) were relative risk factors for binocular myopia (all at P<0.05).Taking monocular myopia as a reference, higher grade (6 versus 1∶4.582[1.193-17.589]), presence of anisometropia (0.141[0.069-0.289]), and irregular pen-holding posture (2.608[1.340-5.075]) were associated factors for binocular myopia (all at P<0.05).According to partial correlation analysis, the spherical equivalent of the right eye of children with incorrect pen-holding posture was negatively correlated with the grip strength ( rs=-0.141, P=0.047). Conclusions:There is an association between pen-holding posture and myopia in school-aged children.Children with greater grip strength and incorrect pen-holding posture may have higher degrees of right eye refractive error.
