Objective:To investigate the correlation between heart rate variability (HRV) and the progression of Parkinson's disease (PD).Methods:A total of 78 patients with PD who received treatment at the Second People's Hospital of Lianyungang from January 2020 to May 2022 were included in this study. According to Hoehn-Yahr (H&Y) staging, patients with PD were divided into three subgroups: mild PD group (H&Y stage < 2), moderate PD group (2 ≤ H&Y < 3), and advanced PD group (H&Y ≥ 3). Another 66 healthy people who concurrently underwent physical examinations in the same hospital were included in the control group. A dynamic electrocardiogram examination was performed in each group for HRV analysis. The Spearman test was used to analyze the correlation between HRV parameters, disease course, and H&Y staging.Results:Standard deviation of all sinus R-R intervals during 24 hours (SDNN), root mean square of successive RR interval differences during 24 hours (RMSSD), percentage normal-to-normal interval deviation greater than 50 ms (PNN50%) during 24 hours, high frequency component (HF), and low frequency component (LF) in the PD group were (94.76 ± 21.65), (23.41 ± 8.67), (3.50 ± 4.32), (96.57 ± 53.84), and (124.92 ± 82.43), respectively, which were significantly lower than (115.65 ± 13.31), (32.48 ± 8.08), (5.61 ± 5.25), (109.11 ± 39.51), and (143.95 ± 72.77) in the control group ( Z = -6.17, -6.22, -3.90, -2.14, -2.53, all P < 0.05). Disease duration, H&Y staging, and the LED level in the mild PD, moderate PD, and advanced PD groups showed an upward trend (all P < 0.05). The Mini-Mental State Examination (MMSE) score in the advanced PD group was significantly higher than that in the mild PD group ( P < 0.05). There was no significant difference in MMSE score between the mild and moderate stages and between moderate and advanced stages ( P > 0.05). Both SDNN and LF in the mild PD group were (110.61 ± 18.53) and (192.02 ± 95.98), respectively, which were significantly lower than (91.97 ± 15.23) and (113.29 ± 56.71) in the moderate PD group ( t = 4.18, 3.55, both P < 0.01). SDNN and LF in the advanced PD group were (80.90 ± 21.03) and (68.10 ± 44.86) respectively, which were significantly lower than those in the moderate PD and advanced PD groups ( t = 4.88, 2.23, 5.54, 3.26, all P < 0.05). There were no significant differences in RMSSD, PNN50%, and HF among the mild PD, moderate PD, and advanced PD groups (all P > 0.05). SDNN and LF were negatively correlated with PD course ( r = -0.36, -0.37, both P < 0.05) and H&Y staging ( r = -0.46, -0.49, both P < 0.05). Conclusion:Sympathetic dysfunction in PD patients is closely related to the onset and progression of PD, and it can reflect the severity of the disease.

OBJECTIVE To investigate the pharmacological components and mechanism of Qingre huoxue decoction in improving myocardial ischemia-reperfusion injury（MIRI）. METHODS Forty-two rats were randomly divided into sham operation group （normal saline）， model group （normal saline）， Qingre huoxue decoction low-dose， medium-dose and high-dose groups （4.94， 9.88， 19.79 g/kg），Qingre huoxue decoction drug-containing serum group （19.79 g/kg） and blank serum group （normal saline）， with 6 rats in each group. Each group was given corresponding drug/normal saline intragastrically， once a day， for consecutive 2 weeks. Twelve hours after last administration， except for serum groups， MIRI model was induced in other groups （only threading without ligation in sham operation group）. After modeling， cardiac histopathology was observed and apoptosis level was detected. UPLC-MS was used to analyze the samples in Qingre huoxue decoction drug-containing serum group and blank serum group. The main pharmacological components were screened with the help of relevant databases. Multivariate statistical methods were used to analyze the differential metabolites and related metabolic pathways. Validation test was performed based on oxidative stress indicators. RESULTS Qingre huoxue decoction could improve the pathological injury of cardiac tissue and decrease apoptosis rate of cardiac cells in MIRI model rats （P＜0.05）. Qingre huoxue decoction drug-containing serum contained 20 main pharmacological components such as baicalin， succinic acid， baicalein， cryptotanshinone， isoferulic acid， protocatechuic aldehyde. Qingre huoxue decoction could significantly up-regulate the levels of 15 metabolites including L-arginine， L-arginine， citric acid， glutathione， β-D- glucose and L-carnitine， and down-regulated the levels of 14 metabolites including arachidonic acid， 3-phosphate-d-glycerol phosphate， linoleic acid， docosahexaenoic acid， phosphatidylcholine and lysophosphatidylcholine （P＜0.05）. These metabolites were mainly involved in energy metabolism， inflammatory injury， oxidative stress and autophagy. Results of validation tests showed that Qingre huoxue decoction could significantly reduce the levels of malondialdehyde， and increased the levels of superoxide dismutase （except for low-dose group） and glutathione peroxidase significantly （P＜0.05）. CONCLUSIONS Qingre huoxue decoction can improve the injury of cardiac tissue in MIRI model rats. Its pharmacological components include baicalin， cryptotanshinone， isoferulic acid， protocatechualdehyde， etc. Furthermore， it may play a protective role in MIRI by improving myocardial energy metabolism， down-regulating oxidative stress， inhibiting inflammation infiltration.

Objective To investigate the predictive value of neutrophil to lymphocyte ratio (NLR) on admission for early neurological deterioration (END) in patients with lacunar stroke.Methods Patients with acute lacunar stroke admitted to the Department of Neurology,the Second People's Hospital of Lianyungang from June 2015 to October 2017 were enrolled retrospectively.END was defined as an increase of ≥2 in the National Institutes of Health Stroke Scale (NIHSS) score within 72 h of admission.Multivariate logistic regression analysis was used to determine the independent risk factors for END.The receiver operating characteristic (ROC) curve was used to analyze the predictive value of NLR for END in patients with lacunar stroke.Results A total of 309 patients with acute lacunar infarction were enrolled,including 180 males (58.2％),aged 59.7 ±7.3 years;65 patients (21.0％) in END group and 244 (79.0％) in non-END group.Multivariate logistic regression analysis showed that after adjusting for other confounders,NLR was an independent risk factor for END in lacunar stroke (odds ratio 4.508,95％ confidence interval 3.128-7.547;P＜0.001).ROC curve analysis showed that the area under the curve of NLR predicting END in patients with lacunar stroke was 0.725 (95％ confidence interval 0.671-0.776;P ＜ 0.001);the optimal cut-off value was 2.32,the sensitivity of predicting END was 61.21％,and the specificity was 72.54％.Conclusion The elevated NLR after admission is an independent risk factor for END in patients with lacunar stroke,which has certain value for early identification and prediction of END.

Visual fixation is an item in the visual function subscale of the Coma Recovery Scale-Revised (CRS-R). Sometimes clinicians using the behavioral scales find it difficult to detect because of the motor impairment in patients with disorders of consciousness (DOCs). Brain-computer interface (BCI) can be used to improve clinical assessment because it directly detects the brain response to an external stimulus in the absence of behavioral expression. In this study, we designed a BCI system to assist the visual fixation assessment of DOC patients. The results from 15 patients indicated that three showed visual fixation in both CRS-R and BCI assessments and one did not show such behavior in the CRS-R assessment but achieved significant online accuracy in the BCI assessment. The results revealed that electroencephalography-based BCI can detect the brain response for visual fixation. Therefore, the proposed BCI may provide a promising method for assisting behavioral assessment using the CRS-R.

OBJECTIVETo detect the expression of transient receptor potential canonical 1 (TRPC1) in a mouse model of ozone-induced lung inflammation and explore its role in lung inflammation.

METHODSIn a mouse model of lung inflammation established by ozone exposure, the expression of TRPC1 in the inflammatory lung tissues was detected by RT-PCR, Wstern blotting and immunohistochemistry.

RESULTSCompared to the control mice, the mice exposed to ozone showed significantly increased expression level of TRPC1 mRNA and protein in the inflammatory lung tissues (P<0.05). Immunohistochemistry showed increased TRPC1 protein expressions in the alveolar epithelial cells, bronchial epithelial cells, and inflammatory cells in the inflammatory lung tissues (P<0.05). The mRNA and protein expression levels of TRPC1 were positively correlated with the counts of white blood cells, macrophages, neutrophils and lymphocytes in the bronchoalveolar lavage fluid of the exposed mice (P<0.01).

CONCLUSIONTRPC1 may play a role in ozone-induced lung inflammation in mice.
