Objective:To study the predictive value of red cell distribution width (RDW)on poor myocardial perfu- sion in patients with acute myocardial infarction(AMI)treated by percutaneous coronary intervention (PCI).Meth-ods:From August 2013 to August 2015,a total of 212 ACS patients undergoing PCI in our hospital were selected. According to RDW of blood analyzer,patients were divided into RDW50% were regar- ded as good myocardial perfusion group (n=134).Clinical data were compared between two groups,and single fac- tor and multi-factor analysis were used to analyze influencing factors for myocardial perfusion.Results:Compared with RDW<13.0% group,there were significant rise in age [(62.85±5.23)years vs.(67.33±6.17)years],and significant reductions in left ventricular ejection fraction [LVEF,(52.37±6.14)% vs.(50.55±5.53)%]and STR [(0.73±0.26)vs.(0.57±0.39)]in RDW≥13.0% group,P<0.05 or <0.01. Compared with good myocardial perfusion group,there were significant reductions in percentage of RDW<13% (59.70% vs.44.87%)and LVEF [(52.25±3.81)% vs.(50.29 ± 4.08)%],and significant rise in age [(63.29 ± 1.93)years vs.(66.42 ± 2.15) years]in poor myocardial perfusion group,P<0.05 all.Multi-factor Logistic regression analysis indicated that age, LVEF and RDW were independent predictors for poor myocardial perfusion (r=3.826~6.525,P<0.01 all).Con-clusion:Red cell distribution width possesses good predictive value for poor myocardial perfusion in patients with a- cute myocardial infarction undergoing percutaneous coronary intervention,which is worth extending in clinic.

Clinical analysis of 38 patients with respiratory involvement in relapsing polychondritis / 中国医师进修杂志

Objective To analyze the clinical characteristics of respiratory involvement in relapsing polychondritis(RPC). Methods The clinical data of 38 patients with respiratory (larynx, trachea and bronchus) involvement in RPC were retrospectively analyzed. Results The incidence of respiratory involvement in patients with RPC was 51.35%(38/74), and the most common symptoms were cough, wheezing, chest tightness and dyspnea. The incidences of erythrocyte sedimentation rate (ESR) increasing, C- reactive protein (CRP) increasing, fibrinogen increasing, D- dimer increased and rheumatoid factor (RF) positive in patients with respiratory involvement were significantly higher than those in patients without respiratory involvement: 47.37% (18/38) vs. 30.56% (11/36), 52.63% (20/38) vs. 33.33% (12/36), 31.58% (12/38) vs. 25.00% (9/36), 21.05% (8/38) vs. 13.89% (5/36) and 36.84%(14/38) vs. 5.56% (2/36), and there were statistical differences (P<0.05). CT was the main method to discover the respiratory involvement, and MRI could detect early cartilage inflammation lesions. Laryngoscope and bronchoscope could early detect mucosa and cartilage damage. Pathology was given priority to lymphocytes and neutrophils infiltration. Some patients had epithelium metaplasia and even canceration. Primary treatment methods were glucocorticoids combined with immunosuppressant. Airway stenosis and infection was the main factors influencing the prognosis of patients. Conclusions The respiratory involvement is not uncommon in RPC, and early CT, MRI, laryngoscope and bronchoscope examination is an important means of early diagnosis.Early glucocorticoid combined immunosuppressive therapy is the key to achieve good prognosis.

Small Interfering RNA of Cystathionineβ-Synthase/Cystathionineγ-Lyase-Derived Hydrogen Sulfide Synthesis Induces Apoptosis of Rat Hepatic BRL Cell Line / 天津医药

Objective To explore the inhibitory effects of endogenous hydrogen sulfide, a novel and important gas-eous transmitter generated in mammalian tissues mainly by cystathionine β-synthase (CBS) or cystathionineγ-lyase (CSE) on the apoptosis of the rat hepatic BRL cell line in physiological condition. Methods BRL cells were cultured, and divid-ed randomly into several groups in different phases of the experiment, including negative-siRNA (control) group, CBS siRNA (CBS 1~3) group and CSE siRNA (CSE 1~3) group, which were used to select the most efficient sequences of siRNAs at 48 or 24-hour transfection. Solution group and (CBS+CSE) siRNA group were added to detect the variation of apoptosis. The BRL cell line was observed and evaluated at 0, 4, 8, 12, and 24 hrs after siRNA transfection. When the mechanisms of the apoptosis were detected, CBS/CSE siRNAs were transfected individually or jointly into BRL cells, and compared with nega-tive-siRNA group to examine the variation. The genic and protein expression of CBS/CSE were detected by RT-PCR and Western blot assay. After transfection of CBS/CSE siRNA, the apoptosis of BRL cells was detected by Hoechst stain and flow cytometry (FCM). The mitochondrial membrane potential (MMP) changes were observed by fluorescent staining. Western blot assay was used to examine the protein expression of intracytoplasm cytochrome C (Cyt C) and cleaved-caspase 3. Re-sults CBS and CSE were observed in BRL cells. After transfection of CBS/CSE siRNA, endogenous H2S generation de-creased and the apoptosis of BRL cells increased. Accordingly, the expression of intracytoplasm-Cyt C and cleaved-caspase 3 increased. Conclusion The inhibition of endogenous H2S synthesis induced the apoptosis of BRL cells under physiologi-cal condition, which may be involved in mitochondrial pathway of apoptosis.

Effect and Interaction of Total Flavonoids and Saponins from Huang-Qi Ge-Gen Decoction on IL-12 and IL-15 of Liver among Diabetes Rats / 世界科学技术-中医药现代化

This study was aimed to explore the effect of total flavonoids and saponins from Huang-Qi Ge-Gen (HQGG) decoction on blood glucose (BG), serum lipid, interleukin-12 (IL-12) and interleukin-15 (IL-15) of liver in diabetes mellitus (DM) rats, in order to investigate their interactions in regulating DM processes. A total of 66 SD rats were randomly divided into 6 groups, which were the normal group, model group (A1B1), control group, total flavonoids group (A2B1), total saponins group (A1B2), and total flavonoids and saponins group (A2B2), with 11 rats in each group. Except the normal group, other groups were intraperitoneal injected with streptozotocin (STZ). And the experiment was according to 2×2 factorial design experiment scheme. The BG was determined before STZ injection and 7 days after the STZ injection. After 30 days, BG, serum lipid, IL-12 and IL-15 of liver were tested. Related indexes were calculated to the weighted composite score. Main and interactive effect of total flavonoids and saponins were studied according to the factorial design experiment scheme. The results showed that compared with the normal group, all indexes of model group showed statistical differences (P<0.05). Total flavonoids and saponins from HQGG decoction can effectively reduce BG, without any interactions between them. Both the total flavonoids and total saponins can reduce serum cholesterol (CHO), triglyceride (TG), liver IL-12 and IL-15. And there were interactive effects. The single use of herb achieved better effects than the combination. It was concluded that total flavonoids and saponins from HQGG decoction can reduce BG, CHO, TG, and liver IL-12 and IL-15 levels in rats. However, the regulation of total flavonoids and saponins on indexes mentioned above showed no additive effect.

Methods The serum level of IL-11, lymphocyte subsets and NK cells were detected by double antibody sandwich enzyme linked immunosorbent assay (ELISA) and flow cytometry in 50 ITP patients (ITP group) and 30 controls (control group). Results The platelet in ITP group [ (30.21 ± 19.40) ×109/L] was lower than that in control group [ (207.21 ± 31.55 ) × 109/L] obviously (P ＜ 0.05 ); the serum level of IL-11 in ITP group [(255.72 ± 163.43) ng/L] was significantly higher than that in control group [ (40.60 ± 5.57 ) ng/L ] (P ＜ 0.05 ). The correlation analysis indicated that the blood serum levels of IL- 11 had negative relationship with the platelet (r = -0.557 ,P ＜ 0.05). The percentage of CD3+ and CD4+ T lymphocyte percentage, CD4+/CD8+ in ITP group were lower and the percentage of CD8+ T lymphocyte was higher than those in control group obviously (P ＜ 0.05 ). The percentage of CD3- CD(16+56) +NK cell in ITP group was lower than that in control group (P ＜ 0.05). Conclusion IL-11, lymphocyte subgroup and NK cell change correlate with ITP morbidity closely, and the IL-11 level and the platelet possibly have the negative feedback control action.

Motor cortex excitability in Parkinson's disease and multiple system atrophy / 中华物理医学与康复杂志

Objective To observe any differences in motor cortex excitability between Parkinson's disease (PD)patients and patients with multiple system atrophy (MSA) and to explore whether motor evoked potentials (MEPs) can be used as an electrophysiological indicator for differentiating the 2 diseases.Methods Thirty-four PD patients, 22 MSA patients and 15 age- and sex-matched healthy control subjeets were included in this study. Relaxed motor thresholds (RMTs), central motor conduction time (CMCTs) and MEP amplitudes (AMPs) were recorded in all three groups. The relationships of RMT, CMCT and AMP with the severity of the disease were observed.Results Average RMT in the PD group was significantly lower than that in the MSA and control groups. Average RMT in the MSA group was also significantly lower than that in the control group. There was no significant difference among the three groups with regard to CMCT. AMP in the PD group was significantly higher on average than in the MSA and control groups, but there was no significant difference between the MSA and control groups. RMT decreased and CMCT shortened progressively with the severity of the disease in the PD group, but not in the MSA group.Conclusions There were differences in motor cortex excitability between PD patients and MSA patients. MEP RMTs and CMCTs may be valuable for identifying PD and MSAc but the clinical significance of the amplitude differences remains to be further explored.

Brainstem auditory evoked potential in Parkinson's disease / 中华物理医学与康复杂志

Objective To evaluate the changes in and the regularity of brainstem evoked potentials (BA-EPs) in Parkiuson's disease (PD) as an objective criterion for early diagnosis and assessment. Methods Thirty-five healthy SD rats were divided into two groups at random. Twenty-two rats were in the experimental group and 13 in the control group. The rats were injected with 8 μg of 6-OHDA solution in the right substantia nigra pars compacta (SNc) and the right ventral tegmentum area (VTA) to create a PD model. The BAEPs of the rats in the experimental group were recorded in a quiet shielded room before the 6-OHDA injection, and one week and two weeks after injec-tion. The control group rats were injected with saline (Ns) and their BAEPs were recorded at the corresponding times. One week and two weeks later, the model rats were injected with apomorphine (APO) and their rotating cycles were counted. Results The Ⅱ , Ⅳ, andV PLs and the Ⅲ-Ⅴ IPLs on the fight ears of the experimental group were prolonged significantly compared with the control group one week after APO injection. There was no significant differ-ence in the BAEPs of the left ears after the first week. After two weeks, the Ⅱ , Ⅳ, and Ⅴ PLs and the Ⅲ-Ⅴ, and Ⅰ-Ⅴ IPLs of the right ears in the experimental group were prolonged significantly compared with the controls and the Ⅳ, and Ⅴ PLs and the Ⅲ -Ⅴ , and Ⅰ-Ⅴ IPLs on their left ears were prolonged significantly. Conclusion In the early course of a PD model in rats, their BAEPs show abnormal changes, which indicates that BAEP could be an ob-jective criterion for early diagnosis and assessment of PD. BAEP may serve as one index of damage in PD. The Ⅲ-Ⅴ PL and Ⅰ-Ⅴ iPL are sensitive indices of PD.

Effects of low frequency repetitive transcranial magnetic stimulation on motor function and excitability of motor cortex in patients with Parkinson's diseaseWANG Ming-wei, SUN Xiu-qiao, GU Ping, MA Xiao-wei, / 中华物理医学与康复杂志

Objective To investigate the effects of low frequency repetitive transcranial magnetic stimulation (rTMS) on motor function and excitability of motor cortex in Parkinson's disease (PD) patients and to study the mechanism of PD from the electrophysiology. Methods Twenty-eight patients with PD received 1 Hz rTMS therapy for 15 d. Thirty normal volunteers were enrolled as controls. Unified Parkinson's Disease Rating Scale (UPDRS) and motor evoked potential (MEP) were adopted as assessment indicators. The excitability of motor cortex was assessed by rest motor threshold (RMT), central motor conduction time (CMCT) and the amplitude of MEP. Results The initial RMTs and CMCTs of PD patients were significantly lower than those of the controls, but MEP amplitudes were not significantly different. After rTMS treatment, motor function of PD patients improved, RMTs increased and CMCTs prolonged. Conclusion In PD patients, motor function disorder and increased motor cortical excitability were observed. Low frequency rTMS may inhibit these changes to some extent.

Objective To study the effects of repeated transcranial magnetic stimulation(rTMS)on Parkinson's plus syndrome(PPS).Methods Fifteen in-patients with PPS were studied between 2005 and 2008.The patients received 1 Hz rTMS at an intensity 30%over the threshold.The rTMS was applied on the hand representive area of the bilateral first motor cortex,50 stimulations on each side,5 arrays,for 5 min,once daily for 15 d.Hamilton's depression scale(HAMD),Hamilton's anxiety scale(HAMA),the unified Parkinson's disease rating scale(UPDRS,which can be subdivided into UPDRS Ⅰ,UPDRS Ⅱ and UPDRS Ⅲ),an activities of daily living scale(ADL),the mini-mental state examination(MMSE)and motor evoked potential(MEP)were assessed before and immediately after 15 d of rTMS treatment. Results Average HAMD,HAMA,UPDRS,UPDRS Ⅱ and UPDRS Ⅲ scores all decreased,and ADL scores increased significantly after treatment,while UPDRSⅠand MMSE scores were unchanged before and after treatment.No significant changes in resting motor threshold or central motor conduction time of the MEP were observed after rTMS treatment. Conclusion Clinical symptoms of PPS patients improved after rTMS treatment and side effects were few.Depression,anxiety,motor function and ability in the activities of daily living improved greatly.Repeated transcranial magnetic stimulation is a potential treatment for PPS patients.There may be no correlation between the effective mechanism of rTMS and cortex excitation.

Effects of low frequency repetitive transcranial magnetic stimulation on motor function and affective disorder in patients with Parkinson's disease / 中华老年医学杂志

Objective To investigate the therapeutic effects of low frequency repetitive transcranial magnetic stimulation (rTMS) on motor function and affective disorder in patients with Parkinson's disease (PD). Methods Twenty PD patients were performed by 1 Hz rTMS therapy for 15 days and 10 matched patients were performed sham stimulation. Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA) and Unified Parkinson' s Disease Rating Scale (UPDRS) were assessed before and 15 days after rTMS treatment. Results After treatment with rTMS, the motor function was improved, and UPDRS total score and UPDRS-Ⅰ , UPDRS-Ⅱ, UPDRS-Ⅲ scores were decreased. UPDRS score was decreased from (38.45±17.33) to (30.95± 17.00) (t=6.780,P<0.01). At the same time, HAMD score was decreased from (12.15±7.62) to (8.75±7.31 ) (t = 5.101, P<0.01 ). The scores of somatization, blockage and sleep disorders were lowered after treatment, but the HAMA score had no significant change(t=1.757, P>0.05). The rigidity of PD patients was improved obviously. All indexes had no improvement in sham stimulation group. Conclusions Low frequency rTMS may improve motor dysfunction and affective disorder in PD patients .

Effect of survivin expression on the maturation of mouse marrow dendritic cells / 重庆医科大学学报

Objective:To study the effect of survivin expression on the mature process of dendritic cells from mouse bone marrow. Methods:The cells in marrow as the precurosor of the dendritic cells were taken from mouse in bioclean condition. Then the iDC were induced by the precurosor of DCs with GM-CSF and IL-4 in medium. ThemDC were induced by the precurosor of DCs with GM-CSF,IL-4,and TNF-? in medium. Survivin was compared by RT-PCR,and Western-bolt among these three stages. Results:The RT-PCR showed that the expression ratios of survivin mRNA among the precurosor of DCs,iDC,and mDC were(0.735?0.081),(0.596?0.073,P

Effects of kangfengshi granules on expressions of osteoprotegerin, RANKL and M-CSF in bone tissues of rats with collagen-induced arthritis / 中西医结合学报

OBJECTIVE: To observe the effects of Kangfengshi Granules (KFSG) on expressions of the mRNAs of osteoprotegerin (OPG), receptor activator of nuclear factor-kappaB ligand (RANKL) and macrophage colony stimulating factor (M-CSF) in bone tissues of rats with collagen-induced arthritis. METHODS: Forty SD rats were randomly divided into four groups: normal control group, untreated group, cyclosporine A (CsA)-treated group and KFSG-treated group. Except the rats in the normal control group, all the other rats received subcutaneous injection of collagen II to establish collagen-induced arthritis (CIA) models. Then the rats in each group were fed normal saline or corresponding drugs for four weeks. Total RNA was extracted from carpal and digital bones. The expressions of OPG, RANKL and M-CSF mRNAs were examined by real-time PCR. RESULTS: The total incidence of arthritis induced by collagen II in the rats was approximately 90%. The expression levels of RANKL and M-CSF mRNAs and the RANKL mRNA/OPG mRNA ratio in the untreated group, KFSG-treated group and CsA-treated group were all significantly higher than those in the normal control group, while the expression levels of OPG mRNA in those three groups were significantly lower than that in the normal control group. The expression level of OPG mRNA in the KFSG-treated group was obviously higher while the expression level of M-CSF mRNA and the RANKL mRNA/OPG mRNA ratio in the same group were both lower as compared with those in the untreated group. CONCLUSION: The molecular mechanism of effects of KFSG on bone erosion and destruction induced by rheumatoid arthritis is closely correlated with up-regulating the expression of OPG mRNA, down-regulating the expression of M-CSF mRNA and RANKL mRNA/OPG mRNA ratio.
