Objective To investigate the effect of Baduanjin on mood and sleep quality in patients with mild to moderate Parkinson disease （PD） and related mechanisms. Methods A total of 110 patients with Hoehn-Yahr stage 1-3 stable PD were randomly divided into Baduanjin group and control group， with 55 patients in each group. The patients in the Baduanjin group received Baduanjin exercise for 30 minutes each time， 5 days a week for 12 weeks， and those in the control group did not do any exercise. Motor function， anxiety and depression mood， and sleep quality were assessed before exercise and after exercise for 12 weeks. Results Compared with the control group， the Baduanjin group had significant improvements in UPDRS-Ⅲ score and 6-minute walk test results. There was a significant difference in Berg Balance Scale in terms of the interaction between time and intervention. There were significant differences between the two groups in HAMA14，HAMD24，and PSQI scores. Conclusions Baduanjin can improve mood and sleep quality in patients with mild to moderate PD.

Objective To investigate the incidence rate of sleep disorders， the features of sleep structure， and related influencing factors in patients with Parkinson disease （PD）.Methods A total of 101 patients with PD who attended the outpatient services or were hospitalized in Department of Neurology， The First Hospital of Hebei Medical University， from August 2016 to April 2022 were enrolled as subjects， and Unified Parkinson Disease Rating Scale Part Ⅲ （UPDRS-Ⅲ） and Hoehn-Yahr （H-Y） staging were used to evaluate motor function and disease severity. The patients with PD were tested using Pittsburgh Sleep Quality Index （PSQI）， Epworth Sleepiness Scale （ESS）， International Restless Legs Scale （IRLS）， and rapid eye movement sleep behavior disorder （RBD） scale， and related information was collected or measured， including body height， body weight， body mass index （BMI）， neck circumference， abdominal circumference， and past medical history. All patients received standardized nocturnal polysomnography （PSG）.Results Among the 101 patients with PD， 87 （86.14%） had sleep disorders. PSG showed that common sleep disorders included RBD，periodic limb movements （PLM）， and obstructive sleep apnea-hypopnea syndrome （OSAHS）. For the PD patients with RBD，the proportion of rapid eye movement sleep was （13.14±8.11）%， with poor subjective sleep quality and obvious depression. PLM was often comorbid with restless legs syndrome in PD patients. OSAHS was more likely to occur in PD patients with greater neck circumference and abdominal circumference，and there was no obvious association between OSAHS and BMI； in addition，excessive daytime sleepiness was more common in PD patients with OSAHS，which had a greater impact on the daytime function of the patents.Conclusion There is a relatively high incidence rate of sleep disorders in PD patients， and PD patients with sleep disorders often have the manifestations of RBD，PLM and OSAHS. PD patients with RBD tend to have poor sleep quality and obvious depression， and OSAHS is more likely to occur in PD patients with greater neck circumference and abdominal circumference，which is not significantly associated with BMI.

ObjectiveTo investigate the protective effect and mechanism of Euphorbia helioscopia aqueous extract （EHE） on mice with chronic obstructive pulmonary disease （COPD） and its influence on precancerous lesion-associated proteins in lung tissues induced by cigarette smoke （CS）. MethodThe COPD model was induced by CS in 60 mice and the model mice were randomly divided into control group， model group， positive drug group （dexamethasone， 2 mg·kg^-1）， and low-， medium-， and high-dose EHE groups （1.875， 3.75， 7.5 g·kg^-1）. The high-performance liquid chromatography （HPLC） method was used to determine the related components in EHE. The changes in end-expiratory pause （EEP）， airway resistance （Penh）， expiratory flow at 50% vital capacity （EF50）， and other pulmonary function indexes were detected by the spirometer. The levels of inflammatory factors， such as interleukin （IL）-2， IL-5， IL-18， IL-17A， and IL-27 in bronchoalveolar lavage fluid （BALF） of mice were detected by high-throughput liquid protein chip technology. Hematoxylin-eosin （HE） staining was used to detect the pathological changes in lung tissues in mice. The content of malondialdehyde （MDA）， myeloperoxidase （MPO）， and glutathione peroxidase （GSH-Px） in lung tissues was determined by the colorimetric method. The mRNA relative expression of tumor necrosis factor-α （TNF-α）， transforming growth factor-β （TGF-β）， matrix metalloproteinase-2 （MMP-2）， matrix metalloproteinase-9 （MMP-9）， and matrix metalloproteinase-12 （MMP-12） was detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. Immunohistochemistry （IHC） was used to detect the expression of tumor protein （P53） and cell proliferation-associated antigen （Ki67） in lung tissues， and Western blot was used to detect the relative expression of tumor suppressor protein （P16）， DNA （cytosine-5）-methyltransferase 1 （DNMT1）， and fragile histidine triad （FHIT） in lung tissues. ResultThe results showed that the main compounds in EHE included phenols （gallic acid and protocatechuic acid） and flavonoids （such as hyperoside， rutin， myricetin， naringenin， quercetin， luteolin， kaempferol， and licorice chalcone A）， among which gallic acid and rutin were the highest in content. Compared with normal group， model group showed increased levels of EEP， EF50， and Penh （P<0.05）， and showed increased MDA and MPO levels （P<0.01） and decreased GSH-Px （P<0.01）， and the model group displayed increased levels of IL-2， IL-5， IL-18， IL-17A， IL-27， TNF-α， TGF-β， MMP-2， MMP-9， and MMP-12 （P<0.05）. And the model group exhibited up-regulated expression of P53， Ki67， and FHIT in lung tissues （P<0.01） and down-regulated expression of DNMT1 and P16 （P<0.01）. Compared with model group， the EHE groups showed decreased EEP and EF50 levels （P<0.05）. The pathological injury of lung tissues in mice of the model group was observed under HE staining， and the pathological injury of basal cell hyperplasia of lung tissues was gradually improved after treatment with EHE. The EHE groups showed reduced levels of MDA and MPO （P<0.01） and increased GSH-Px （P<0.01）. The EHE groups displayed decreased levels of IL-2， IL-5， IL-18， IL-17A， IL-27， TNF-α， TGF-β， MMP-2， MMP-9， and MMP-12 （P<0.05）. And the EHE groups showed down-regulated Ki67 and FHIT in lung tissues （P<0.05） and up-regulated expression of P53 and DNMT1 （P<0.05）. ConclusionEHE can protect mice from COPD and inhibit precancerous lesions， and the mechanism may be related to the inhibition of inflammation and oxidative stress response， regulation of protease and antiprotease imbalance， and regulation of epithelial cell growth.

随着铜绿假单胞菌（铜绿）的耐药性逐年增强，铜绿感染已经成为公共医疗卫生的重点关注问题。线粒体自噬及其介导的线粒体功能障碍在多种细菌感染中已被报道，但线粒体功能障碍在宿主调控铜绿感染中的作用尚不明确。因此，本研究建立铜绿刺激小鼠巨噬细胞感染模型和小鼠急性铜绿感染模型，探讨铜绿是否通过诱导线粒体自噬改变线粒体功能，进而影响宿主免疫炎症反应和细胞毒性，并通过监测生存率和肺组织病理学变化进一步确定线粒体自噬在小鼠铜绿体内感染模型中的作用。结果表明，铜绿引起小鼠腹腔巨噬细胞线粒体功能障碍，并通过线粒体自噬途径清除铜绿刺激引起的活性氧（ROS）累积，从而抑制铜绿引起的促炎性细胞因子分泌并增强细胞毒性。体内实验进一步确认线粒体自噬在铜绿体内感染中的作用。

Objective:To investigate the characteristics of serum cytokine IL-4 and IFN- γ levels in patients with chronic insomnia with mild cognitive impairment (MCI), and to further explore the relationship between cognitive function and IL-4 and IFN-γ in patients with chronic insomnia.Methods:Sixty-two patients with chronic insomnia were divided into MCI group( n=30) and non-MCI group( n=32) according to the scores of Montreal cognitive assessment(MoCA), mini-mental state examination(MMSE) score and chief complaint of cognitive decline. Pittsburgh sleep quality index(PSQI), Hamilton depression scale(HAMD 24) and Hamilton anxiety scale 14 item(HAMA 14) were evaluated. Serum IL-4 and IFN-γ were detected by flow fluorescence, correlation analysis and regression analysis were carried out. Results:The levels of IL-4 and IFN-γ in MCI group were significantly lower than those in non-MCI group (IL-4: 0.875(0.143, 1.655)μg/L, 1.855(0.813, 2.723)μg/L; IFN-γ: 0.450(0.173, 1.163)μg/L, 1.160(0.483, 3.075)μg/L, all P<0.05). There was no significant difference in IFN- γ/IL-4, PSQI, HAMA 14 and HAMD 24 scores between MCI group and non-MCI group. IL-4 was positively correlated with the total score of MoCA( r=0.318, P<0.05), orientation( r=0.324, P<0.05)and delayed recall( r=0.368, P<0.01). The results of multivariate regression showed that IL-4 had significant effects on MCI in patients with chronic insomnia( B=2.161, OR=8.682, 95% CI=2.058~36.633, P=0.003). Conclusion:The cognitive function of chronic insomnia is closely related to serum IL-4 and IFN-γ, and serum IL-4 has a protective effect on cognition in chronic insomnia patients. Therefore, it can be speculated that cytokines may be an important pathophysiological link of cognitive change in chronic insomnia patients.

Objective To investigate the correlation between chronic insomniacs' sleep quality and age,gender,education level,anxiety,depression and sympathetic skin response (SSR) in chronic insomniacs.Methods General information of 197 outpatients with chronic insomnia was recorded,including age,gender and education,etc.They were tested by Pittsburgh's Sleep Quality Index (PSQI),Hamilton's Anxiety Scale (14 item version) (HAMA14),Hamilton's Depression Scale (24 item version)(HAMD24) and Sympathetic Skin Response (SSR).Distribution properties of different age,gender and education groups were studied.Chronic insomniacs were divided into mild insomnia group (7 ≤ PSQI ＜ 14)and moderate-severe insomnia group (PSQI ≥ 14).Dependency relation analysis and stepwise linear regression analysis were conducted among indices of PSQI scores,HAMA14 scores and total score,HAMD24 scores and total score,SSR positive incidence.Results Among 197 chronic insomniacs (male,50 cases,25.4％;female,147 cases,74.6％),insomniacs aged over 40 accounted for 77.2％.Female patients were older than male patients with statistical significance,of whom those aged 40-60 years accounted for the highest proportion of 37.1％.Female patients with less education (junior high school and below)accounted for the highest proportion of 50.3％ (73/197),whose education level was generally lower than male patients.Among 197 chronic insomniacs,104 cases (52.8％,99/197) had mild insomnia and 93cases (47.2％) had moderate-severe insomnia.Total score of HAMA14 of patients with moderate-severe insomnia was significantly higher than that of patients with mild insomnia (16.47 ± 5.40 vs 12.51 ± 4.53;t =5.552,P＜0.01).There was statistically significanct difference in subitem HAMA14 scores of anxiety somatization factor (4.31 ± 2.26 vs 5.90-3.10,t =5.600,P ＜ 0.01) and spiritualized anxiety factor (10.5 ± 72.97 vs 8.20 ± 3.00,t =4.157,P ＜ 0.01) between mild and moderate-severe groups with insomnia.Total score of HAMD24 of patients with moderate-severe insomnia was significantly higher than that of patients with mild insomnia (18.04 ± 5.91 vs 13.41 ± 5.05;t=3.931,P＜ 0.01).There was statistically significanct difference in scores of most HAMD24 subitems including anxiety/somatization (3.56 ± 1.51 vs 2.94 ± 1.28;t =3.110,P =0.002),cognitive dysfunction (2.91 ± 1.68 vs 2.17 ± 1.57;t=3.191,P=0.002),retardation (2.331 ±1.31 vs 1.72 ±1.22;t=3.939,P=0.01),dyssomnia (4.51 ± 1.54 vs 3.01 ± 1.80;t =6.228,P ＜0.01) and hopelessness factor (2.29 ± 1.46 vs 1.66 ± 1.07,t =3.459,P =0.001;except body weight and diurnal variation factor) between groups with different degrees of insomnia.SSR abnormal incidences of moderate-severe insomniacs were significantly higher than that of mild insomniacs.The proportion of poorly differentiated waveform and not elicited waveform in SSR abnormal groups had statistically significant difference.The Pearson correlation analysis showed that PSQI scores in chronic insomnia patients and HAMA14,HAMD24 score as well as abnormal rate of SSR were positively correlated (r =0.439,0.465,0.249,all P ＜ 0.01).Conclusions Chronic insomnia was commonly seen in middle-aged women with education level of junor high school and below.The degree of sleep quality and anxiety,depression as well as the abnormal rate of SSR was positively correlated in patients with chronic insomnia.

Objective: To investigate the effect of the treatments for obstructive sleep apnea hypopnea syndrome (OSAHS) on the resistant hypertension (RH) of patients. Methods: Eighty patients with OSAHS and RH (blood pressure could not be controlled under 140/90 mmHg (1 mmHg=0.133 kPa) even with more than three kinds of antihypertensive drugs including diuretics) received surgery or continuous positive airway pressure (CPAP) treatment. The results of polysomnography monitoring, ambulatory blood pressure monitoring, and the dosage of antihypertensive medication were recorded before and six months after the treatment. Results: Apnea hypopnea index (AHI) decreased from (32.9±10.8) before treatment to (9.4±6.5) after treatment, while the lowest oxygen saturation (SaO₂) increased from (0.682±0.062) to (0.884±0.056), with significant differences (t value was 18.863 and 26.614, respectively; both P<0.001). Twenty-four hours systolic blood pressure (SBP)/diastolic blood pressure (DBP) decreased respectively from ((150.5±9.8)/(97.8±7.3)) mmHg to ((140.7±6.8)/(88.6±6.3)) mmHg, daytime SBP/DBP decreased from ((154.3±8.9)/(100.6±7.4)) mmHg to ((144.8±5.8)/(91.3±5.5)) mmHg, and nighttime SBP/DBP decreased from ((145.5±8.8)/(93.8±6.4)) mmHg to ((135.8±5.7)/(84.6±5.9)) mmHg, with significant differences (t value was 7.832, 6.903, 7.005, 6.848, 8.025, 7.554, respectively; all P<0.001). The reduction of nighttime SBP /DBP was ((11.5±2.2)/(10.2±3.1)) mmHg, and the reduction of daytime SBP/DBP was ((9.0±2.8)/(7.9±3.5)) mmHg. The reduction of nighttime SBP/DBP was more obvious than daytime SBP/DBP, with significant differences (t value was 9.732 and 6.936, respectively; both P<0.001). Before treatment, nighttime blood pressure decrease rate below 10% was showed in 75 percent of patients, and after treatment, this rate only in 37.5 percent of patients (χ²=22.857, P<0.01). The numbers of required antihypertensive drugs decreased in 45 (56.3%) cases, the average numbers of antihypertensive drugs decreased from (3.2±0.4) before treatment to (2.6±0.5) after treatment, with a significant difference (t=9.276, P<0.01). Conclusions After treatment of OSAHS, the blood pressure of the patients with OSAHS and RH dropped significantly, the circadian rhythm of blood pressure condition was better, the varieties of antihypertensive drugs taken in these patients were reduced significantly.

OBJECTIVE To investigate the effect of continuous positive airway pressure(CPAP) on blood pressure in patients with obstructive sleep apnea hypopnea syndrome(OSAHS) and refractory hypertension.METHODS Fifty five OSAHS patients with refractory hypertension were treated with CPAP.Ambulatory blood pressure monitoring was performed to the patients before and 6 months after the treatment.RESULTS After treatment,the blood pressure of all the patients decreased at different degrees.The mean of 24 h systolic blood pressure(SBP) and 24 h diastolic blood pressure(DBP) decreased from (136.4±2.8)mmHg and (85.6± 1.7)mmHg to (126.9± 1.0)mmHg and (76.8± 1.3)mmHg,the differences were statistically significant(P＜0.05).The mean decrease of 24 h SBP and DBP were (9.6 ± 3.0)mmHg and (8.7± 2.0)mmHg.The decrease value of 24 h SBP and DBP were concerned with apnea and hypopnea index.The numbers of antihypertensive drugs decreased in 31 patients.CONCLUSION After CPAP treatment,the blood pressure of the patients with OSAHS and refractory hypertension dropped significantly,and the varieties of antihypertensive drugs taken in these patients were reduced significantly.

BACKGROUND:Currently, neural stem celltransplantation can be performed through three main approaches:local lesions, blood circulation, and cerebrospinal fluid.
OBJECTIVE:To review the transplantation of neural stem cells or neural precursor cells via the cerebrospinal fluid in the treatment of central nervous system diseases.
METHODS:A computer-based search of PubMed and CHKD databases was performed to retrieve articles concerning transplantation of neural stem cells via the cerebrospinal fluid, and its application and therapeutic mechanism in the treatment of central nervous system diseases in both animal experiment and clinic study published from 2000 to 2009.
RESULTS AND CONCLUSION:It is suitable for neural stem cellsurvival, proliferation, and differentiation in the cerebrospinal fluid. Transplantation of neural stem cells via the cerebrospinal fluid is effective and feasible to treat central nervous system diseases. However, some problems have not been solved, such as the source of neural stem cells, the optimal time window and celldose, the safety and the long-term effect. Further studies are needed to pave the way for the intrathecal injection of neural stem cells in the treatment of central nervous system diseases.

Objective To evaluate the association between serum 25-hydroxyvitamin D3 [25 (OH) D3],parathyroid hormone,and arterial stiffness in patients with type 2 diabetes.Methods Serum 25 (OH) D3 and parathyroid hormone(PTH) were determined in a cross-sectional sample of 258 patients aged 30 years and over.Arterial stiffness was assessed by pulse wave velocity(PWV) obtained with a VP-1000 pulse wave unit.Fasting plasma HbA1c,lipid profile,calcium,and high sensitive-C reactive protein were determined.Results (1)The prevalence of vitamin D3 deficiency was high(79.84％) in patients with type 2 diabetes.(2) Those with lowered serum vitamin D3 levels had raised PWV [(1610.76 ± 142.70 vs 1527.95 ± 58.02) cm/s,P＜0.05].(3) Multiple stepwise regression analysis showed that 25 (OH) D3 was an impact factor of PWV risk score,which was independent of age,duration of diabetes,and systolic blood pressure(β =-0.256,P＜0.01).(4) Serum PTH was positively correlated with PWV (r =0.210,P ＜ 0.05) and systolic blood pressure (r =0.229,P ＜ 0.05),but negatively correlated with 25 (OH) D3 (r =-0.153,P ＜ 0.05).Conclusions 25 (OH) D3 deficiency is common in patients with type 2diabetes,and a low serum 25 (OH) D3 level is significantly associated with increased arterial stiffness in these patients.The association of serum PTH with arterial stiffness may result via changes in vitamin D and blood pressure.
