Background Platelet parameters are important indicators of cardiovascular risk, and environmental pollutants such as polychlorinated biphenyls (PCBs) may impair platelet function through oxidative stress. Objective To investigate the differential effects of single and mixed exposure to PCBs on platelet parameters among individuals with normal glucose tolerance (NGT), impaired fasting glucose (IFG), and type 2 diabetes mellitus (T2DM), and to evaluate the potential modifying role of a healthy lifestyle. Methods This study included 2249 participants (including 707 with NGT, 759 with IFG, and 783 with T2DM). Plasma PCB concentrations were measured using triple quadrupole gaschromatography-tandem mass spectrometry. Generalized linear regression was used to assess the associations between individual PCB congeners and platelet parameters. Quantile g-computation (QGC) and Bayesian kernel machine regression (BKMR) models were used to evaluate the overall effects of PCBs mixture exposure on platelet parameters across different glycemic states, as well as its interaction with healthy lifestyle score (HLS). Results Generalized linear regression analyses showed significant differences in the effects of PCBs on platelet parameters across different glycemic states (P<0.05). After adjusting for confounders, PCBs mixture exposure was significantly associated with lower platelet counts (PLT) in individuals with NGT (b=−10.60, 95%CI: −16.48, −4.71) and IFG (b=−12.91, 95%CI: −18.90, −6.92), whereas no significant association was observed in individuals with T2DM (P=0.051). Mean platelet volume (MPV) and platelet-large cell ratio (P-LCR) increased significantly with higher PCBs exposure levels across all three groups (P<0.05). BKMR analysis showed a positive association between PCBs mixture exposure and P-LCR, with the strongest association observed in the NGT group. Furthermore, a significant interaction was observed between HLS and PCBs mixture exposure, and a higher HLS attenuated the effects of PCBs on P-LCR. Conclusion Glycemic glycemic states may modify the effects of PCBs on platelets. Individuals with NGT appear more sensitive to PCBs exposure, whereas the T2DM state may attenuate this effect. Moreover, healthy lifestyles, including not smoking, moderate alcohol consumption, maintaining moderate-to-high physical activity, a healthy diet, and an appropriate body mass index (BMI), may mitigate the adverse effects of most PCBs on platelet parameters.

The theory of five spirits(mind,eternal soul,corporeal soul,consciousness and will)is an important part of traditional Chinese medicine(TCM)theory,which reveals the human mental and psychological activities.Five-spirit theory takes the shape of modern cognitive psychology.Language is an important part of cognitive activities.Under the guidance of the five-spirit theory of TCM,and by combining the research results of modern cognitive psychology,this paper initially constructs a language processing model,and proposes that heart-mind,spleen-consciousness,kidney-will,and liver-soul are all involved in the formation of language.Moreover,the pathogenesis of post-stroke aphasia(PSA)is explored from the perspective of the five spirits.It is proposed that PSA refers to the comorbidity of body and spirit,and its pathogenesis is related to the disorders of the five spirits.After analyzing the clinical manifestations of PSA,it is suggested that malnutrition of heart-mind and insufficient kidney-will contribute to the pathogenesis of auditory comprehension and reading obstacles in patients with PSA,and the deactivation of liver-soul is closely related to spontaneous speech and naming obstacles.The treatment of PSA should be focused on nourishing blood and tranquilizing mind,enhancing consciousness and strengthening will,and suppressing liver to tranquilize soul.And the prescriptions of Pingbu Zhenxin Pills,Zhiyi Decoction plus Dingzhi Pills,and Dinghun Decoction can be chosen for modified use.The acupuncture and moxibustion can also be used for PSA,by performance mainly on the acupoints of heart meridians,pericardial meridians,spleen meridians,kidney meridians and liver meridians.The syndrome differentiation and treatment system for PSA with the combination of Chinese medicine and acupuncture based on the five-spirit theory makes up for the shortcomings of stress on the physique while ignorance of the spirit in the conventional zang-fu organ syndrome differentiation,and expands the methods for early intervention of PSA with TCM and approaches to improve the prognosis of rehabilitation.

Objective To establish a method for acquisition, perfusion, preservation and transportation of the genetically modified pig kidneys. Methods An eight genetically modified pig was utilized as experimental subject. Prior to kidneys procurement, the health status of the pig was assessed through hematology examination, and the vascular structure of the kidneys was examined using imaging techniques. Following kidneys acquisition, the pig kidneys were perfused and subsequently packaged into the cryogenic storage container labeled "For Organ Transportation Only" for interprovincial transport after communicating the transportation process with transportation department. To evaluate pathological damage to the pig kidneys, a serious of methods were employed such as hematoxylin-eosin (HE) staining, real-time fluorescent quantitative polymerase chain reaction (RT-qPCR), terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) fluorescence staining and enzyme-linked immune absorbent assay (ELISA). Results The preoperative examination of the eight genetically modified pig showed that the serum creatinine was 73.2 μmol/L, blood urea nitrogen was 2.8 mmol/L and hemoglobin was 116 g/L, all within the normal range, indicating normal renal function. CT angiography revealed no lesions in the pig kidneys, and no dilation, stenosis or premature branching of the blood vessels. The total time of obtaining the left and right kidneys from the eight genetically modified pig was (125 ± 10) min, with a blood loss of (20 ± 2) mL. The warm ischemia times were 3 min and 7 min, respectively. The perfusion and trimming times of the left and right kidneys were 36 min and 41 min, respectively. After perfusion, both kidneys were white and moist. The cold preservation and transportation time was 8 h. HE staining showed that some glomeruli were shrunk, and the lumens of the surrounding renal tubules were slightly depressed and swollen with partial inner membrane shedding and microvacuoles formed when the kidneys were preserved for 8 h. The level of cysteinyl aspartate-specific proteinase-3 messenger RNA in the kidneys tissue gradually increased with the extension of cold preservation time after 2 h (P<0.05). TUNEL fluorescence staining showed that only a small number of cells underwent apoptosis after 8 h of cold preservation, which was not significantly different from that at 0 h (P>0.05). ELISA results showed that the contents of lactate dehydrogenase (LDH) and creatinine in the preservation solution remained relatively stable, but the content of kidney injury molecule 1 (KIM-1) gradually increased with the extension of preservation time, suggesting that the pig kidneys had mild injury. Conclusions By establishing methods for acquisition, perfusion, preservation and transportation of the kidneys from genetically modified donor pig, it is possible to effectively and reliably use genetically modified pig kidneys for xenotransplantation.

Objective To retrospectively analyze multicenter data from domestic sources, aiming to explore the link between intrahepatic cholangiocarcinoma (ICC) tumor size and prognosis, establishing a classification system based on tumor size. Methods Between December 2011 and September 2018, 280 ICC patients from 13 hospitals were included. The tumor size prognosis cutoff was identified by the minimum P-value method, and the classification's overall survival related effectiveness was assessed by Kaplan-Meier analysis. Results All 280 patients were divided into the group of tumor maximum diameter ≤4 cm and >4 cm. Tumor size was confirmed as an independent prognosis factor by multivariate COX regression analysis (HR=2.110, 95% CI: 1.358-3.280). Conclusions The tumor size dichotomy classification system based on the Chinese patient group can expediently predict ICC prognosis and offers an important basis for selecting post-operative individualized adjuvant therapy and follow up plans.

Objective:To explore the therapeutic strategy for laryngeal cysts in infants. Methods:A retrospective analysis of the clinical data of 19 children with laryngeal cysts treated in Kunming Children's Hospital from January 2020 to January 2023. All patients were diagnosed through electronic laryngoscopy examination. Twelve neonates were admitted to the neonatal intensive care unit. Five of them received mechanical ventilation with tracheal intubation before surgery due to severe respiratory distress, and seven received oxygen therapy with a head mask. The remaining seven children were admitted to Department of Otolaryngology Head and Neck Surgery, of which three cases were treated with oxygen therapy through a mask during sleep due to frequent shortness of breath during sleep. All patients underwent low-temperature plasma radiofrequency ablation under general anesthesia to remove the cysts. Results:Three newborns were unable to have their tracheal tubes removed due to complications with pneumonia after surgery, while the rest of the children were able to have their tubes successfully removed after complete anesthesia, and no gastric tubes were placed. All postoperative respiratory difficulties in the children disappeared, and there were no complications such as bleeding, hoarseness, or laryngeal stenosis. Five pediatric patients had incomplete relief of laryngeal ringing symptoms one month after surgery, and electronic laryngoscopy diagnosed laryngeal softening. Regular follow-up is recommended. One child relapsed 4 months after surgery and underwent a follow-up surgery six months later without recurrence. Conclusion:Endoscopic low-temperature plasma radiofrequency ablation is an effective surgical method for treating laryngeal cysts, with a low postoperative recurrence rate. Laryngeal cysts may be accompanied by laryngeal softening, which may be a possible reason for the postoperative symptoms not improving.

Objective:To explore the association between cardiometabolic multimorbidity(CMM), the number of cardiometabolic diseases(CMD)and mild cognitive impairment(MCI)among the older adults in urban communities.Methods:Based on the baseline data of the Hubei Memory and Aging Cohort Study(HMACS)from 2018 to 2023, CMM was defined as the coexistence of two or more CMDs(Type 2 diabetes, stroke and ischemic heart disease). Multivariate logistic regression was employed to examine the association between CMM, the number of CMDs and the prevalence of MCI, as well as subgroup heterogeneity.Results:This study included 6 113 urban participants aged ≥65 years(55.6% were female; mean age 71.9±5.7 years). The prevalence of MCI was 19.3%, with an increasing trend observed as the number of CMD increased(17.7%, 20.5%, 24.6%, 28.3%). After adjusting for all variables, a significant association was observed between CMM group and the prevalence of MCI( OR: 1.24, 95% CI: 1.01-1.52)compared with the non-CMM group.As the number of CMD increased, the prevalence of MCI increased( Ptrend=0.011), but the association was only significant in the group with two CMDs.Subgroup analyses revealed that in males( OR: 1.48, 95% CI: 1.10-2.00), those with more than 9 years of education( OR: 1.52, 95% CI: 1.15-2.02), and those with hypertension( OR: 1.33, 95% CI: 1.05-1.67), CMM was significantly associated with MCI, and the association with MCI increased significantly with the increase in the number of CMDs(all Pfor trend <0.05). Conclusions:Among urban community-dwelling older adults aged ≥65 years in China, CMM and the cumulative number of CMDs are significantly associated with an increase of MCI, particularly in males, those with higher education levels, and those with hypertension.In the future, the need for enhanced MCI screening for CMM patients should be strengthened, and targeted prevention and control of cognitive impairment should be implemented for high-risk populations.

Objective:To observe the characteristics of gastrointestinal tract symptoms in patients with Parkinson′s disease (PD) and analyze the characteristics of these symptoms in patients with different PD subtypes.Methods:A total of 297 PD patients who were admitted to the Neurology Department of the Second Affiliated Hospital of Soochow University from November 2022 to March 2024 were enrolled. The gastrointestinal symptoms of PD patients were evaluated using Drooling Severity and Frequency Scale (DSFS), Sialorrhea Clinical Scale for Parkinson′s disease (SCS-PD), Drooling Rating Scale (DRS), Eating Assessment Tool 10 (EAT-10), Gastroparesis Cardinal Symptom Index (GCSI), and Rome Ⅳ diagnostic criteria. The patients were grouped based on the presence or absence of gastrointestinal symptoms. Additionally, they were stratified according to disease duration (≤2 years, 2-5 years, 5-10 years, and>10 years) and motor symptom subtype [tremor-dominant (TD) vs. postural instability and gait difficulty (PIGD)]. One-way ANOVA and logistic regression analysis were applied to examine between-group differences while Spearman correlation analysis was employed to assess correlations between clinical symptoms.Results:The average age of the patients with PD was 67.0 (60.0, 72.0) years, and 161 (54.2%) were male. The incidence of PD combined with gastrointestinal symptoms was, in descending order: constipation (191, 64.3%), salivation (155, 52.2%), gastroparesis (93, 31.3%), and dysphagia (68, 22.9%). Compared with PD patients without gastrointestinal symptoms, those with symptoms had higher scores in the RBD-HK [12.0 (5.0, 21.5) vs. 5.0 (0.0, 9.0), Z=-3.74, P=0.017], ESS [6.0 (2.0, 12.0) vs. 3.0 (0.0, 6.0), Z=-3.20, P=0.023], and MDS-UPDRS Part Ⅰ [9.0 (5.0, 14.0) vs. 5.0 (2.3, 9.0), Z=-3.61, P=0.014]. The severity of sialorrhea and deglutition disorders, along with the incidence of constipation, all increased with longer disease duration. Patients with the PIGD subtype had higher GCSI scores than those with the TD subtype [0.0 (0.0, 1.9) vs. 0.0 (0.0, 0.0), Z=-3.57, P=0.007]. Across the cohort, sialorrhea, deglutition disorders, gastroparesis, and constipation were positively associated with the H-Y stage, MDS-UPDRS Ⅰ, HAMD, NMSQ, and SCOPA-AUT; EAT-10 scores were negatively correlated with MoCA ( r=-0.171, P<0.05); and GCSI scores were negatively correlated with MMSE and MoCA ( r=-0.154, r=-0.169, both P<0.05). Conclusions:Overall, 84.5% of the patients with PD had one or more gastrointestinal symptoms, and the incidence and severity of gastrointestinal symptoms increased with disease duration. The severity of gastroparesis was higher in the PIGD group than in the TD group. The scores of all gastrointestinal symptoms were positively correlated with the H-Y stage and MDS-UPDRS Ⅰ, while the GCSI scores were negatively correlated with the cognitive scores.
