Development and Validation of the Missed Nursing Care Tool for Pre-Operative Patients with Lung Cancer in China.

Introduction: Current research suggests that missed nursing care is widespread in preoperative lung cancer patients in China, and preoperative airway management nursing care for lung cancer patients is not standardized. Missed nursing care for preoperative lung cancer patients, on the other hand, is rarely investigated, particularly from the patient's perspective. This study aimed to develop and validate the MISSCARE Survey for pre-operative patients with lung cancer in China. Methods: This study generated the preliminary draft of the MISSCARE Survey - Lung Cancer Patient (MS-LCP) and tested its reliability and stability through three rounds of lung cancer resection (494, 50, and 309 cases, respectively). 20 patients and 6 experts determined the face and content validity. EFA and CFA assessed construct and convergent validity. Internal consistency, including Cronbach's alpha, Spearman-Brown reliability, and re-test reliability, was also examined. Results: The scale contained 15 items, including specific care, communicative care, timely care, and basic care. KMO was 0.932 (> 0.6), and Bartlett's Test of Sphericity showed P = 0.000 (<0.05). The attribution factor's item loads ranged from 0.765 to 0.853, accounting for 82.20% of the variation. The scale's Cronbach's alpha, Spearman-Brown, and retest reliability were 0.945, 0.879, and 0.824. CFA showed goodness of fit (RMSEA = 0.021, χ2/df = 1.138, GFI = 0.900, AGFI = 0.945, CFI = 0.996, NFI = 0.967, IFI = 0.996). For each dimension, AVE ranged from 0.555 to 0.717 (>0.50) and CR from 0.861 to 0.904 (>0.70). Conclusion: The MS-LCP was reliable and valid in this study, making it appropriate for the Chinese lung cancer patient population. This tool is more objective in its presentation of missed nursing care, assisting nursing staff in optimizing nursing procedures before surgery, increasing the implementation of higher-quality tumor care, and promoting the recovery of lung cancer surgery patients.

Evaluation methods of a rat sciatic nerve crush injury model.

BACKGROUND: The rat sciatic nerve crush injury model is one of the most commonly used models to research peripheral nerve injury (PNI), however, the evaluation of the model preparation lacks exact standards. This study aimed to investigate accurately assessment methods for research concerning the rat sciatic nerve crush injury. METHODS: The sciatic nerve crush injury model of was performed using the FST toothless forceps. The corresponding locations and pressures of different ratchet strengths were assessed by using CMAP, behavioral, and morphological methods. RESULTS: In each group of PNI, motor and sensory functions were gradually restricted on the injured side of rats as the applied pressure increased. CMAP was more sensitive to nerve injury arising out of the force values obtained from the forceps. CONCLUSIONS: As a sensitive indicator for PNI, the neuroelectrophysiological examination was more likely to reflect the morphological changes of injured nerves. These findings may provide a standardized approach to sciatic crush injury modelling.

Data mining-based detection of the clinical effect on motion style acupuncture therapy combined with conventional acupuncture therapy in chronic neck pain.

BACKGROUND: Neck pain is the most common symptom of cervical spondylosis. OBJECTIVE: To discuss the indications for conventional acupuncture therapy (CAT) and motion style acupuncture therapy (MSAT) combined with CAT in neck pain patients using data mining. METHOD: Seventy-six participants with neck pain were recruited and randomly divided into two paralleled groups. Participants in intervention group received two-course MSAT at Houxi (SI3) and CAT at local neck region, while the control group received CAT at neck only. Take the SF-36 score scale and pain pressure threshold (PPT) values as the raw data and use data-mining to evaluate the clinical effect of two treatments. RESULT: Both groups have the best effect after one-time and one-course treatment. The main factors influencing effect most are Role-Emotional (RE), Physical Functioning (PF) and Social Functioning (SF) in intervention group, while it transfers to General Health (GH), RE and SF in control group. To patients in intervention group who scores 41.70 to 68.70 in PF before treatment, MSAT can effectively improve the restriction of activities and play an analgesic effect; to patients in control group who score 56.09 to 66.09 in GH before treatment, CAT may have curative effect. CONCLUSION: Both MSAT and CAT can improve the life-quality of neck pain patients. Patients with high general health status before treatment can choose CAT, while patients who score mild to moderate decline in physiological function can choose MSAT combined with CAT.

Fasting blood glucose to HDL-C ratio as a novel predictor of clinical outcomes in non-diabetic patients after PCI.

Background The present study was to assess the prognostic value of fasting blood glucose to high-density lipoprotein cholesterol ratio (GHR) in non-diabetic patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI). Methods and results A total of 6645 non-diabetic patients from two independent cohorts, the CORFCHD-PCI study (n=4282) and the CORFCHD-ZZ (n=2363) study, were enrolled in Clinical Outcomes and Risk Factors of Patients with Coronary Heart Disease after PCI. Patients were divided into two groups according to the GHR value. The primary outcome included all-cause mortality (ACM) and cardiac mortality (CM). The average follow-up time was 36.51 ± 22.50 months. We found that there were significant differences between the two groups in the incidences of ACM (P=0.013) and CM (P=0.038). Multivariate Cox regression analysis revealed GHR as an independent prognostic factor for ACM. The incidence of ACM increased 1.284-times in patients in the higher GHR group (hazard ratio [HR]: 1.284 [95% confidence interval [CI]: 1.010-1.631], P<0.05). Kaplan-Meier survival analysis suggested that patients with high GHR value tended to have an increased accumulated risk of ACM. However, we did not find significant differences in the incidence of major adverse cardiac events, main/major adverse cardiovascular and cerebrovascular events (MACCE), stroke, recurrent myocardial infarction (MI) and bleeding events. Conclusions The present study indicates that GHR index is an independent and novel predictor of ACM in non-diabetic CAD patients who underwent PCI.

D-Dimer to Fibrinogen Ratio as a Novel Prognostic Marker in Patients After Undergoing Percutaneous Coronary Intervention: A Retrospective Cohort Study.

The role of activation of the coagulation and fibrinolysis system in the pathogenesis and prognosis of cardiovascular diseases (CVDs) has drawn wide attention. Recently, the D-dimer to fibrinogen ratio (DFR) is considered as a useful biomarker for the diagnosis and prognosis of ischemic stroke and pulmonary embolism. However, few studies have explored the relationship between DFR and cardiovascular disease. In our study, patients were divided into 2 groups according to DFR value: the lower group (DFR < 0.52, n = 2123) and the higher group (DFR ≥ 0.52, n = 1073). The primary outcome was all-cause mortality (ACM) and cardiac mortality (CM). The average follow-up time was 37.59 ± 22.24 months. We found that there were significant differences between the 2 groups in term of ACM (2.4% vs 6.6%, P < 0.001) and CM (1.5% vs 4.0%, P < 0.001). Kaplan-Meier analyses showed that elevated DFR had higher incidences of ACM (log rank P < 0.001) and CM (log rank P < 0.001). Multivariate Cox regression analyses showed that DFR was an independent predictor of ACM (HR = 1.743, 95%CI: 1.187-2.559 P = 0.005) and CM (HR = 1.695, 95%CI: 1.033-2.781 P = 0.037). This study indicates that DFR is an independent and novel predictor of long-term ACM and CM in post-PCI patients with CAD.

ALT-to-Lymphocyte Ratio as a Predictor of Long-Term Mortality in Patients with Normal Liver Function Presenting Coronary Artery Disease after Undergoing PCI: A Retrospective Cohort Study.

BACKGROUND: Alanine aminotransferase (ALT) is referred as liver transaminase and predominantly expressed by hepatocytes. Previous evidences showed that high levels of ALT were reversely associated with short- and long-term outcomes in patients with myocardial infarction. Besides, low lymphocyte has been demonstrated to be significantly correlated with adverse clinical outcomes in coronary artery disease (CAD). However, evidences about the relationship between ALT-to-lymphocyte ratio (ALR) and outcomes in CAD patients with normal liver function are limited. The aim of this study was to assess the relationship between ALR and clinical outcomes in patients with CAD. METHODS: This is a retrospective cohort study, and a total of 3561 patients were enrolled in Clinical Outcomes and Risk Factors of Patients with CAD after percutaneous coronary intervention (PCI), from January 2013 to December 2017. After excluding patients with liver dysfunction, we finally enrolled 2714 patients. These patients were divided into two groups according to ALR value: the lower group (ALR < 14.06, n = 1804) and the higher group (ALR ≥ 14.06, n = 910). The average follow-up time was 37.59 ± 22.24 months. RESULTS: We found that there were significant differences between the two groups in the incidence of all-cause mortality (ACM) (P < 0.001) and cardiac mortality (CM) (P=0.010). Kaplan-Meier survival analysis suggested that CAD patients with higher ALR tended to have an increased accumulated risk of ACM and CM (log rank P < 0.001 and P=0.006, respectively). Multivariate Cox regression analysis showed that ALR was an independent predictor of ACM (hazard ratio (HR) = 2.017 (95% confidence interval (CI): 1.289-3.158), P=0.002) and CM (HR = 1.862 (95% CI: 1.047-3.313), P=0.034). We did not find significant difference in the incidence of major adverse cardiovascular events (MACEs) and major adverse cardiovascular and cerebrovascular events (MACCEs) between the two groups after adjustments of confounders. CONCLUSION: Our results indicate that ALR is an independent predictor of long-term adverse outcomes in CAD patients who underwent PCI.

GTS-21 ameliorates polymicrobial sepsis-induced hepatic injury by modulating autophagy through α7nAchRs in mice.

BACKGROUND: Previous studies showed that GTS-21, a selective alpha 7 nAchR agonist, can trigger anti-inflammatory effects and improve the survival of septic animals. However, whether GTS-21 affects autophagy responses remains unclear. Here, we tested the hypothesis that GTS-21 ameliorates sepsis-induced hepatic injury by modulating autophagy in mice. METHOD: C57BL/6 male mice were randomly separated and categorized into four groups: the sham group, and CLP group subjected to caecal ligation and puncture (CLP, a model of polymicrobial sepsis). The CLP + GTS-21 group was administered GTS-21 immediately after CLP challenge. α-Bungarotoxin (an alpha 7 nAchR antagonist) was injected before CLP was performed, and then, after CLP challenge, GTS-21 was administered to α-BGT + CLP + GTS-21 group. The hepatic tissue and blood samples were harvested 6 h after the operation. RESULTS: CLP challenge increased TNF-α and IL-6 production, and hepatic enzyme alanine aminotransferase and aspartate transaminase levels. CLP also elevated the expression of hepatic LC3-II, sequestosome-1/p62, Atg7 and Atg5. The administration of GTS-21 inhibited pro-inflammatory cytokine production and hepatic enzymatic marker expression, promoted the expression of LC3-II, Atg7, Atg5, and decreased the expression of p62, which could be reversed by α-BGT treatment. CONCLUSION: Our findings suggested that α7nAchR is involved in diminishing hepatic damage by inhibiting inflammatory responses and improving autophagy in mice with polymicrobial sepsis.

Triglyceride to high-density lipoprotein cholesterol ratio as a predictor of long-term mortality in patients with coronary artery disease after undergoing percutaneous coronary intervention: a retrospective cohort study.

BACKGROUND: It has been confirmed that the triglyceride to high-density lipoprotein cholesterol ratio (THR) is associated with insulin resistance and metabolic syndrome. However, to the best of our knowledge, only a few studies with small sample sizes have investigated the relationship between THR and coronary artery disease (CAD). Therefore, we aimed to assess the correlation between the THR and long-term mortality in patients with CAD after undergoing percutaneous coronary intervention (PCI) in our study that enrolled a large number of patients. METHODS: A total of 3269 post-PCI patients with CAD were enrolled in the CORFCHD-ZZ study from January 2013 to December 2017. The mean follow-up time was 37.59 ± 22.24 months. Patients were divided into two groups according to their THR value: the lower group (THR < 2.84, n = 1232) and the higher group (THR ≥ 2.84, n = 2037). The primary endpoint was long-term mortality, including all-cause mortality (ACM) and cardiac mortality (CM). The secondary endpoints were major adverse cardiac events (MACEs) and major adverse cardiac and cerebrovascular events (MACCEs). RESULTS: In our study, ACM occurred in 124 patients: 30 (2.4%) in the lower group and 94 (4.6%) in the higher group (P = 0.002). MACEs occurred in 362 patients: 111 (9.0%) in the lower group and 251 (12.3%) in the higher group (P = 0.003). The number of MACCEs was 482: 152 (12.3%) in the lower group and 320 (15.7%) in the higher group (P = 0.008). Heart failure occurred in 514 patients: 89 (7.2%) in the lower group and 425 (20.9%) in the higher group (P < 0.001). Kaplan-Meier analyses showed that elevated THR was significantly related to long-term ACM (log-rank, P = 0.044) and the occurrence of heart failure (log-rank, P < 0.001). Multivariate Cox regression analyses showed that the THR was an independent predictor of long-term ACM (adjusted HR = 2.042 [1.264-3.300], P = 0.004) and heart failure (adjusted HR = 1.700 [1.347-2.147], P < 0.001). CONCLUSIONS: An increased THR is an independent predictor of long-term ACM and heart failure in post-PCI patients with CAD.

Effect of vitamin D on ventricular remodelling in heart failure: a meta-analysis of randomised controlled trials.

OBJECTIVES: The level of vitamin D is considered to be associated with the development and progression of heart failure (HF). However, it is still unclear whether supplementation of vitamin D could improve ventricular remodelling in patients with HF. This study aimed to systematically evaluate the influence and safety of additional vitamin D supplementation on ventricular remodelling in patients with HF. DESIGN: This study is a meta-analysis of randomised controlled trials (RCTs). SETTING: The PubMed, EMBASE, CNKI, Cochrane library, Web of Science databases and grey literature were searched for RCTs regarding the effect of vitamin D on ventricular remodelling in patients with HF (from database creation to October 2017). RevMan V.5.3 software was employed for data analysis. PARTICIPANTS: Seven RCTs with a total of 465 patients, including 235 cases in the vitamin D group and 230 cases in the control group, were included. PRIMARY AND SECONDARY OUTCOME MEASURES: Left ventricular end-diastolic dimension (LVEDD), left ventricular ejection fraction (LVEF) and the incidence of adverse reactions. RESULTS: Compared with the control group, a decrease in the LVEDD (mean difference (MD)=-2.31 mm, 95% CI -4.15 to -0.47, p=0.01) and an increase in the LVEF (MD=4.18%, 95% CI 0.36 to 7.99, p=0.03) were observed in the vitamin D group. Subgroup analysis also revealed a reduced LVEDD in adults (>18 years) and adolescents (<18 years) of the vitamin D group relative to that in those of the control group. High-dose vitamin D (>4000 IU/day) was more effective at reducing the LVEDD than low-dose vitamin D (<4000 IU/day). Moreover, vitamin D supplementation was more effective at reducing the LVEDD and increasing the LVEF in patients with reduced ejection fraction than in patients without reduced ejection fraction. CONCLUSION: Vitamin D supplementation inhibits ventricular remodelling and improves cardiac function in patients with HF. TRIAL REGISTRATION NUMBER: CRD42017073893.

Zishenpingchan granules for the treatment of Parkinson's disease: a randomized, double-blind, placebo-controlled clinical trial.

Levodopa preparations remain the preferred drug for Parkinson's disease. However, long-term use of levodopa may lead to a series of motor complications. Previous studies have shown that the combination of levodopa and Zishenpingchan granules (consisting of Radix Rehmanniae preparata, Lycium barbarum, Herba Taxilli, Rhizoma Gastrodiae, Stiff Silkorm, Curcuma phaeocaulis, Radix Paeoniae Alba, Rhizoma Arisaematis, Scorpio and Centipede) can markedly improve dyskinesia and delay the progression of Parkinson's disease, with especially dramatic improvements of non-motor symptoms. However, the efficacy of this combination has not been confirmed by randomized controlled trials. The current study was approved by the Hospital Ethics Committee and was registered in the Chinese Clinical Trial Register (registration number: ChiCTR-INR-1701194). From December 2014 to December 2016, 128 patients (72 males and 56 females, mean age of 65.78 ± 6.34 years) with Parkinson's disease were recruited from the Department of Neurology of Longhua Hospital and Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine in China. Patients were equally allocated into treatment and control groups. In addition to treatment with dopamine, patients in treatment and control groups were given Zishenpingchan granules or placebo, respectively, for 24 weeks. Therapeutic efficacy was assessed using the Unified Parkinson's Disease Rating Scale, on-off phenomenon, Hoehn-Yahr grade, Scales for Outcomes in Parkinson's disease-Autonomic, Parkinson's disease sleep scale, Hamilton Anxiety Scale, Hamilton Depression Scale, Mini-Mental State Examination, and the Parkinson's Disease Quality of Life Questionnaire. Artificial neural networks were used to determine weights at which to scale these parameters. Our results demonstrated that Zishenpingchan granules significantly reduced the occurrence of motor complications, and were useful for mitigating dyskinesia and non-motor symptoms of Parkinson's disease. This combination of Chinese and Western medicine has the potential to reduce levodopa dosages, and no obvious side effects were found. These findings indicate that Zishenpingchan granules can mitigate symptoms of Parkinson's disease, reduce toxic side effects of dopaminergic agents, and exert synergistic and detoxifying effects.

Muramyl Dipeptide Enhances Thermal Injury-Induced Autophagy and Inflammatory Cytokine Response of Lungs via Activation of NOD2/Rick Signaling Pathway in Rats.

OBJECTIVE: Nucleotide-binding oligomerization domain 2 (NOD2) is the innate receptor of muramyl dipeptide (MDP). Our previous study revealed that MDP could enhance thermal injury-induced inflammatory cytokine production and organ function injury in rats. The present study was to determine the effect of MDP on autophagy and NOD2/receptor-interacting serine/threonine protein kinases (RICK) signaling pathway of lung injury after thermal injury. METHODS: Forty male Sprague-Dawlay rats were randomly divided into four groups: normal control (NC) group, MDP group, Scald group, and MDP + Scald group. Scald group only suffered 20% total body surface area third-degree (TBSA) thermal injury. MDP group was only administered 5.0 mg/kg MDP through the left femoral vein; 5.0 mg/kg MDP was administered through the left femoral vein at 24 h after thermal injury in the MDP + Scald group. RESULTS: TBSA thermal injury (20%) not only significantly increased the plasma inflammatory cytokines production, but also elevated the expression of LC3-I/II, the accumulation of autophagosome in the lung tissue. Compared with the Scald group, MDP + Scald double hit led to more serious inflammatory responses and higher expression of NOD2 mRNA, RICK, NF-κB p65, LC3-I/II, and the accumulation of more autophagosome in the lung tissue. CONCLUSIONS: MDP enhances thermal injury-induced autophagy and proinflammatory cytokine response of lung injury, which could be achieved via activating the NOD2/RICK signaling pathway in rats.

The Role of Erbin in GTS-21 Regulating Inflammtory Responses in MDP-Stimulated Macrophages.

OBJECTIVE: To explore the role of Erbin protein and nucleotide-binding oligomerization domain 2/receptor-interacting serine/threonine protein kinases (NOD2/RICK) in GTS-21 activating cholinergic anti-inflammatory pathway. METHODS: Experiments were randomly divided into four groups: normal control (NC) group, muramyl dipeptide (MDP) group, 10 µg/mL MDP, GTS-21 (GTS) group, 10 µg/mL MDP plus 50 µg/mL GTS-21 (α7 nAChRs agonist), Erbin shRNA interference (sh-Erbin) group: sh-Erbin RNA plus 10 µg/mL MDP and 50 µg/mL GTS-21. We extract specimens at the point of 1, 6, and 24 h after stimulation of MDP in Raw264.7 macrophages. RESULTS: After stimulation of MDP, the NLR2 mRNA, RICK and Erbin protein, nuclear factor (NF)-κB activity, the pro-inflammatory cytokines tumor necrosis factor (TNF)-α and HMGB1 were significantly increased in MDP group (P <0.05). The expression peak of TNF-α is at 1 h. The peak of HMGB1 is at 24 h. Compared with MDP group, the NLR2 mRNA, RICK, NF-κB, TNF-α, and HMGB1 were significantly decreased, but the Erbin was increased in GTS group (P <0.05). Compared with GTS group, the NLR2 mRNA, RICK, NF-κB, TNF-α, and HMGB1 increase in sh-Erbin group (P <0.05). CONCLUSION: GTS-21 could significantly inhibit MDP-induced pro-inflammatory cytokines responses via activating cholinergic anti-inflammatory pathway, and the Erbin might be the key negative regulatory protein in NLR2/RICK signal transduction.

Impact of Physician-Coordinated Intensive Follow-Up on Long-Term Medical Costs in Patients with Unstable Angina Undergoing Percutaneous Coronary Intervention.

BACKGROUND: To investigate the impact of professional physician-coordinated intensive follow-up on long-term expenditures after percutaneous coronary intervention (PCI) in unstable angina (UA) patients. METHODS: In this study, there were 669 UA patients who underwent successful PCI and followed up for 3 years, then divided into the intensive follow-up group (N = 337), and the usual follow-up group (N = 332). Patients were provided with detailed discharge information and individualized follow-up schedules. The intensive group received the extra follow-up times and medical consultations, and all patients were followed up for approximately 3 years. RESULTS: At the 3-year mark after PCI, the cumulative major adverse cardiac events (MACE), recurrence of myocardial ischemia, cardiac death, all-cause death and revascularization in the intensive group were lower than in the usual group. Additionally, the proportion of good medication adherence was significantly higher than in the usual group (56.4% vs. 46.1%, p < 0.001). The hospitalization daytime, total hospitalization cost and total medical cost in the intensive group were lower. Multiple linear regression showed that diabetes, hypertension, intensive follow-up and good medication adherence were associated with emergency and regular clinical cost (p < 0.05), the re-hospitalization cost (p < 0.05) and the total medical cost (p < 0.05) of patient care. Intensive follow-up and good adherence were negatively correlated with the cost of re-hospitalization (standardized coefficients = -0.132, -0.128, p < 0.05) and total medical costs (standardized coefficients = -0.072, -0.086, p < 0.05). CONCLUSIONS: Intensive follow-up can reduce MACE, improve medication adherence and save long-term total medical costs, just by increasing the emergency and regular clinical visits cost in UA patients after PCI.

The initial stone-free rate was 70.9% (39/55), total stone-free rate was 89.1% (49/55). 2 patients with postoperative blood transfusion, 1 case of super-selective renal artery embolization to stop bleeding, 3 patients had postoperative fever, 1 case of septic shock, 2 cases of conservative treatment of a small amount of liquid chest, 1 case of apparent low back pain due to urine extravasation, given pain medication.no other serious complications. Conclusions By special urology ultrasound probe guide, use the kidney dome puncture path method to do standard channel assisted MPCNL combined with EMS for the treatment of staghorn calculi accompanied with pyonephrosis, its benefits in high stone-free rate, low renal pelvis pressure, high security rate, low complication rate and so on. Therefore, it is worthy of clinical application.

Anti-apoptotic effect of Shudipingchan granule in the substantia nigra of rat models of Parkinson's disease.

Levodopa is the gold-standard treatment for Parkinson's disease. However, although it alleviates the clinical symptoms, it cannot delay the progressive apoptosis of dopaminergic neurons or prevent motor complications in the long term. In the present study, we investigated the effect of Shudipingchan granule on neuronal apoptosis in a rat model of Parkinson's disease, established by injecting 6-hydroxydopamine into the substantia nigra pars compacta and ventral tegmental area. We then administered levodopa (20 mg/kg intraperitoneally, twice daily) with or without Shudipingchan granule (7.5 mL/kg intragastrically, twice daily), for 4 weeks. The long-term use of levodopa accelerated apoptosis of nigral cells and worsened behavioral symptoms by activating the extracellular signal-regulated kinase pathway and downstream apoptotic factors. However, administration of Shudipingchan granule with levodopa reduced expression of phosphorylated extracellular signal-regulated kinase 1/2 and Bax, increased tyrosine hydroxylase and Bcl-2, reduced apoptosis in the substantia nigra, and markedly improved dyskinesia. These findings suggest that Shudipingchan granule suppresses neuronal apoptosis by inhibiting the hyperphosphorylation of extracellular signal-regulated kinase and downregulating expression of anti-apoptotic genes. Shudipingchan granule, used in combination with levodopa, can effectively reduce the symptoms of Parkinson's disease.

Immediate effects of scalp acupuncture with twirling reinforcing manipulation on hemiplegia following acute ischemic stroke: a hidden association study.

Data mining has the potential to provide information for improving clinical acupuncture strategies by uncovering hidden rules between acupuncture manipulation and therapeutic effects in a data set. In this study, we performed acupuncture on 30 patients with hemiplegia due to acute ischemic stroke. All participants were pre-screened to ensure that they exhibited immediate responses to acupuncture. We used a twirling reinforcing acupuncture manipulation at the specific lines between the bilateral Baihui (GV20) and Taiyang (EX-HN5). We collected neurologic deficit score, simplified Fugl-Meyer assessment score, muscle strength of the proximal and distal hemiplegic limbs, ratio of the maximal H-reflex to the maximal M-wave (Hmax/Mmax), muscle tension at baseline and immediately after treatment, and the syndromes of traditional Chinese medicine at baseline. We then conducted data mining using an association algorithm and an artificial neural network backpropagation algorithm. We found that the twirling reinforcing manipulation had no obvious therapeutic difference in traditional Chinese medicine syndromes of "Deficiency and Excess". The change in the muscle strength of the upper distal and lower proximal limbs was one of the main factors affecting the immediate change in Fugl-Meyer scores. Additionally, we found a positive correlation between the muscle tension change of the upper limb and Hmax/Mmax immediate change, and both positive and negative correlations existed between the muscle tension change of the lower limb and immediate Hmax/Mmax change. Additionally, when the difference value of muscle tension for the upper and lower limbs was > 0 or < 0, the difference value of Hmax/Mmax was correspondingly positive or negative, indicating the scalp acupuncture has a bidirectional effect on muscle tension in hemiplegic limbs. Therefore, acupuncture with twirling reinforcing manipulation has distinct effects on acute ischemic stroke patients with different symptoms or stages of disease. Improved muscle tension in the upper and lower limbs, reflected by the variation in the Hmax/Mmax ratio, is crucial for recovery of motor function from hemiplegia.

Association between left ventricular end-diastolic pressure and coronary artery disease as well as its extent and severity.

Patients with myocardial ischemia exhibit increased left ventricular end-diastolic pressure (LVEDP). The study was to evaluate the relationship between LVEDP measured by left cardiac catheterization and coronary artery disease (CAD) as well as its extent and severity evaluated by coronary angiography (CAG). 912 patients who underwent CAG and left cardiac catheterization were enrolled. There were 313 patients without CAD and 599 with CAD according to CAG. The extent and severity of coronary artery was evaluated by number of vessels and Gensini score. Analyze the correlation of LVEDP and CAD as well as its extent and severity. LVEDP was significantly higher in CAD patients than non-CAD (9.58±5.78 mmHg vs 10.9±5.46 mmHg, P<0.001), and was correlated independently with the presence of CAD (OR = 0.11, per 5 mmHg increase, 95% CI 1.02-1.29, P = 0.02). LVEDP was increased with an increase of number of vessels. By linear regression analysis, LVEDP was significantly associated with Gensini score (standardized ß = 0.034, P = 0.001). In non-CAD group, LVEDP was only correlated with age (r = 0.123, P = 0.030). In conclusion, our findings suggest that elevated LVEDP was significantly associated with CAD as well as its extent and severity. LVEDP was only correlated with age in non-CAD patients. LVEDP measurement provides incremental clinical value for CAD and non-CAD patients.

Effect of zishenpingchan granule on neurobehavioral manifestations and the activity and gene expression of striatal dopamine d1 and d2 receptors of rats with levodopa-induced dyskinesias.

This study was performed to observe the effects of Zishenpingchan granule on neurobehavioral manifestations and the activity and gene expression of striatal dopamine D1 and D2 receptors of rats with levodopa-induced dyskinesias (LID). We established normal control group, LID model group, and TCM intervention group. Each group received treatment for 4 weeks. Artificial neural network (ANN) was applied to excavate the main factor influencing variation in neurobehavioral manifestations of rats with LID. The results showed that overactivation in direct pathway mediated by dopamine D1 receptor and overinhibition in indirect pathway mediated by dopamine D2 receptor may be the main mechanism of LID. TCM increased the efficacy time of LD to ameliorate LID symptoms effectively mainly by upregulating dopamine D2 receptor gene expression.

[Effects of docosahexaenoic acid on ion channels of rat coronary artery smooth muscle cells].

OBJECTIVE: To investigate the effects of docosahexaenoic acid (DHA) on large-conductance Ca(2+)-activated K(+) (BK(Ca)) channels and voltage-dependent K(+) (K(V)) channels in rat coronary artery smooth muscle cells (CASMCs), and evaluate the vasorelaxation mechanisms of DHA. METHODS: BK(Ca) and K(V) currents in individual CASMC were recorded by patch-clamp technique in whole-cell configuration. Effects of DHA at various concentrations (0, 10, 20, 40, 60 and 80 µmol/L) on BK(Ca) and K(V) channels were observed. RESULTS: (1) DHA enhanced IBK(Ca) and BK(Ca) tail currents in a concentration-dependent manner while did not affect the stably activated curves of IBK(Ca). IBK(Ca) current densities were (68.2 ± 22.8), (72.4 ± 24.5), (120.4 ± 37.9), (237.5 ± 53.2), (323.6 ± 74.8) and (370.6 ± 88.2)pA/pF respectively (P < 0.05, n = 30) with the addition of 0, 10, 20, 40, 60 and 80 µmol/L DHA concentration, and half-effect concentration (EC(50)) of DHA was (36.22 ± 2.17)µmol/L. (2) IK(V) and K(V) tail currents were gradually reduced, stably activated curves of IK(V) were shift to the right, and stably inactivated curves were shifted to the left in the presence of DHA. IK(V) current densities were (43.9 ± 2.3), (43.8 ± 2.3), (42.9 ± 2.0), (32.3 ± 1.9), (11.7 ± 1.5) and (9.6 ± 1.2)pA/pF respectively(P < 0.05, n = 30)post treatment with 0, 10, 20, 40, 60 and 80 µmol/L DHA under manding potential equal to +50 mV, and EC(50) of DHA was (44.19 ± 0.63)µmol/L. CONCLUSION: DHA can activate BK(Ca) channels and block K(V) channels in rat CASMCs, the combined effects on BK(Ca) and K(V) channels lead to the vasodilation effects of DHA on vascular smooth muscle cells.

[Echocardiographic standardized myocardial segmentation features in patients with left ventricular noncompaction].

OBJECTIVE: To analyze the echocardiographic standardized myocardial segmentation features in patients with left ventricular noncompaction (LVNC). METHODS: Echocardiographic characteristics of 9 patients with LVNC were analyzed and the localization of lesions were determined according to the standardized myocardial segmentation (SMS) recommended by American Heart Association (AHA). RESULTS: Loose trabeculation in the myocardial lesions were evidenced in all LVNC patients. Communication between deep intertrabecular recess and LV cavity was evident with color flow imaging. According to SMS of AHA, noncompaction of ventricular myocardium was localized in apical segment in all 9 patients, in apical segment of the inferior wall (IW) in 9 patients, in apical segment of the lateral wall (LW) in 7 patients, in middle segment (MS) of IW in 7 patients, in MS of LW in 6 patients. One NC segment was also evidenced in apical segment and MS of septal ventricular wall, basal segment of IW and LW and right ventricular apex, respectively. NC was not found in left ventricular anterior wall. CONCLUSION: Echocardiographic standardized myocardial segmentation is helpful to diagnose LVNC and NC was mostly localized in the apical segments of LVNC patients.
