Objective To develop a radiology algorithm and test its the accuracy in distinguish pacing in the septum from the other parts. Methods One hundred patients were implanted with double-chamber pacemakers. Sites of the leads were verified by two-dimensional echocardiography, and the patients were divided into 4 groups according to the echocar?diography:septal right ventricular outflow tract group(RVOT), RVOT anterior free wall group, mid septum group, and anteri?or septum group (near to the anterior free wall ). An algorithm was developed according to radiological characteristics in the 45° left anterior oblique (LAO45° ) view and the 30° right anterior oblique (RAO30° ) view. Then its sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were tested . Results The algorithm has high sensitivi?ty and specificity, which were 90%and 97%respectively. The positive predictive value and negative predictive value were 90% and 97% respectively. Conclusion The radiology algorithm we developed have a high sensitivity and specificity in identifying the site of the leads.

OBJECTIVE: This study conduct a qualitative synthesis and quantitative meta-analysis of VFAFI, aimed to study whether it is a useful treatment for UVCP. METHOD: Electronic databases PubMed, YZ365. COM, WANFANG DATA, CMJD, CHKD,CNKI were searched using relevant keywords. Reported treatment outcomes were clustered into three categories,i. e. subjective, perceptual,acoustic,aerodynamic,and stroboscopic. Meta-analyses were performed on studies with numerical results using random effects model. RESULT: Five articles were identified with a total of 404 patients. All the studies reported significant improvements or decrease after VFAFI in each category of outcome measurements. Meta-analysis demonstrated a significant increase or decrease in all categories. Adverse effects include slight inflammatory reponse can resolve spontaneously within 1 month. The recurrence rate after VFAFI was high due to the self absorption. NNE and Jitter of post-operation is lower than pre-operation,there is no significantly change between the control group and experimental group; F0, Shimmer and MPT of post-operation is higher than pre-operation, there is no significantly change between the control group and experimental group. CONCLUSION The invasiveness and morbidity of VFAFI are low and the side effects are self-limited. Meta-analyses demonstrated significant improvements or decreased from both objective and subjective measurements. Further controlled studies with longer follow-up periods and more person were included may evaluate the effectiveness of VFAFI more reliably.

Objective: To analyze the chemical constituents of Polygonum multiflorum extract which may cause human liver cell damage and to explore the mechanism. Methods: Raw and processed Polygonum multiflorum were extracted by 70% ethanol, then raw and processed Polygonum multiflorum water-eluted material (RW and PW), 50% ethanol-eluted material (R50 and P50) and 95% ethanol-eluted material (R95 and P95) were obtained by absorbing through AB-8 macroporous resin, followed by water, 50% ethanol and 95% ethanol elution in order. The water extracts of raw and processed Polygonum multiflorum (RWE or PWE) were obtained by boiling them in water as usual. Normal human liver L02 cells were treated by different concentrations of eluted Polygonum multiflorum materials for different time, and the cell growth inhibition of each group was determined by methylthiazolyldiphenyl-tetrazolium bromide method. The chemical constituents which had a significant cytotoxicity to L02 cells were analyzed by high-performance liquid chromatography (HPLC). Morphological changes of L02 cells were observed by Giemsa staining and cell cycle distribution was observed by flow cytometry. Results: It was found that 95% ethanol-eluted extracts of raw and processed Polygonum multiflorum showed significant growth inhibition on normal human liver L02 cells, while the other components showed no significant inhibition on cell growth. HPLC analysis showed that the main component in 95% ethanol-eluted extract of raw and processed Polygonum multiflorum was emodin at content of (18.53+/-2.96)% and (10.28+/-1.34)% respectively. Cell cycle analysis showed that 95% ethanol-eluted material of Polygonum multiflorum and emodin had a similar significant effect of S phase arrest and all could induce L02 cell apoptosis. Conclusion: The main part of Polygonum multiflorum causing liver cell damage is the 95% ethanol-eluted extract, and emodin is one of the important chemical constituents leading to liver cell damage.

Objective To investigate the influence of group psychotherapy on clinical effect of apoplectic hemiplegia. Methods Sixty patients of apoplectic hemiplegia were randomized into treatment group and control group, 30 cases in each group. Both groups were given ordinary clinical treatment and rehabilitation training, and treatment group was given group psychotherapy additionally. HAMD-17 and MBI were evaluated after four weeks, and the incidence of depression of the two groups was compared. Results The treatment group was obviously superior to control group in improvement of depression level and activities of daily living (P<0.05). The incidence of depression in the treatment group was lower than that in control group (P<0.05). Conclusion The group psychotherapy is effective in treating depression state of stroke patients, improving activities of daily living, and reducing depression incidence.

Objective To compare the efficacy of cardiac resynchronization therapy (CRT) on chronic heart failure (CHF) patients with different left bundle branch block (LBBB) morphologies. Methods Patients(n=45)who were treated with CRT were enrolled. According to the intrinsic ECG morphologies, patients were divided into 1)genuineLBBB group (n=32) who present negative dominant V1 and V2 lead wave (QS or rS);mid-QRS notching or slurring in at least 2 leads of Vl, V2, V5, V6, I and aVL as well as QRS duration≥140 ms in male or≥130 ms in female and 2)falseLBBB group (n=10) who meet traditional standards but fail to meet“genuine”LBBB diagnostic standard. The QRS duration, echocardiographic indi?ces and New York Heart Association (NYHA) Functional Classification were evaluated at the 12 months follow-up. CRT re?sponder was defined as patient with≥1 decrease in NYHA class and/or with≥15%reduction in left ventricular end-systolic volume (LVESV). CRT super-responder was defined as patient with≥30%reduction in LVESV. Results There was no dif?ference in basic characteristics of patients between groups. At the 12 months follow-up, 20 patients in genuine LBBB group and 6 patients infalseLBBB group were identified as responders (P>0.05). Compared with those infalseLBBB group, the responders ingenuineLBBB group showed better improvement in left ventricular ejection fraction and left ven?tricular end diastolic diameter (LVEDD) (both P<0.05). Conclusion Left bundle branch block morphology is less predic?tive for the efficacy of CRT. However, patients who show response to CRT withgenuineLBBB profile may get more bene?fits from CRT treatment than the patients withfalseLBBB profile.

Objective To investigate the cause and countermeasures of frequent shocks in patients with implantable cardioverter defibrillators (ICD). Methods Eighty ICD patients with heart failure and malignant ventricular arrhythmias were followed up, including sixty-two male and eighteen female patients. There were 35 patients with single-chamber ICD, 23 with dual-chamber ICD and 22 with three-chamber ICD. Patients in this study were followed up for 1-6 years to analyze the reasons for ICD discharge. According to the specific circumstances, patients were treated. Results Twenty-three pa-tients in 80 patients suffered from shock treatment. Ten patients (12.5%) experienced frequent shocks. The causes of fre-quent shock included repeated episodes of ventricular tachycardia, invalid shock due to increased defibrillation threshold (DF) and false identification of the frequent episodes of paroxysmal ventricular tachycardia or arrhythmias. The management included the identification process adjustment of ventricular tachycardia and supraventricular tachycardia, increased num-bers of beats of ventricular tachycardia judgment and increase the basic pacing rate. The anti-arrhythmic drugs should be combinedly used, especially metoprolol and amiodarone. The ICD shock was significantly reduced after parameter optimiza-tion and anti-arrhythmic therapy. Conclusion The ICD shocks were effectively reduced with rational use of anti-arrhyth-mic drugs and valid ICD programming.

24 cases of hypoparathyroidism, 24 cases of normal control were included. The levels of enzymes, concentration of Ca were measured in all cases. The electrocardiogram was carried out in the hypoparathyroidism group carries. The levels of CK, CK-MB, BHDH, LDH and AST were significantly higher in patients with hypoparathyroidism than in normal control cases(P＜0.05), especially the levels of CK and CK-MB (P＜0.01). After the treatment, the electrocardiogram and enzymes basically returned to normal. The changes of enzymes in patients with hypoparathyroidism may play a benchmark about the severity and treatment.

Objective To investigate the therapeutic effect of modulated medium frequency current therapy (MMFCT) combined with infrared therapy on patients of acute facial neuritis. Methods A total of forty-six patients with acute facial neuritis were divided into two groups (observation group and control group) randomly and medially. Every patient received medication. Meanwhile, observation group received MMFCT and infrared therapy. Before the treatment, and after two and four weeks of treatment, Portmann scale were used to evaluate the autonomic movements of the facial expression muscles on both sides. After 4 weeks of treatment, the outcome was evaluated by House-Brackmann facial nerve grading system. Results There were no significant differences in Portmann scales before treatment between two groups. Portmann scales were higher in observation group than those of control group after two and four weeks of treatment (P<0.05). With the duration of treatment, Portmann scales were increased successively in two groups. The significant difference was found in multiple comparisons between groups. After 4 weeks of treatment, the efficacy was significant in the observation group, compared with control group, the difference was significant (P<0.05). Conclusion Modulated medium frequency current therapy combined with infrared therapy have a better effect than isolated medication.

Objective To observe the effect of the 8-word bandage on the walking ability of stroke patients with knee hyperextension. Methods Fifty patients with stroke combined with knee hyperextension were randomly divided into the observation group and the control group with 25 cases in each group. The control group was treated with conventional methods, including Bobath technology, Brunnstrom therapy and motor relearning primarily rehabilitation training. In addition to the conventional methods, patients in the observation group used 8-word bandage to fix knee joint in walking training. Before and after 8 weeks of treatment, Holden walking function classification, 10-meter maximum walking speed and improved Barthel index were adopted to evaluate the walking ability, maximum walking speed and the life ability of the patients. Results There were no significant differences in the scores before treatment between the two groups. The Holden walking function classification, the 10-meter maximum walking speed and the Barthel index scores were significantly improved after 8-week treatment in both two groups (P<0.05), and patient conditions were more significantly improved in the observation group than those of the control group (P<0.05). Conclusion Using 8-word bandage to fix knee joint can significantly improve knee hyperextension in patients with stroke, so as to improve the walking ability and activities of daily living.

Aim To investigate the effects and mechanisms of CCK-8 on IL-1? induced proliferation of RSC-364, a rat fibroblast-like synovial cell line. Methods MTT colorimetric assay and Western blot were used to measure cell proliferation and p38MAPK phosphorylation level to elucidate the mechanism of CCK-8 in IL-1? induced RSC-364 proliferation. Results CCK-8 significantly inhibited IL-1?-induced RSC-364 proliferation at 10 -12 , 10 -10 , 10 -8 , 10 -6 mol ? L -1 , and IL-1?-activated p38MAPK activity at 10 -10 , 10 -8 , 10 -6 mol?L -1 in a dose-dependent manner. The effect of CCK-8 was blocked by CR1409 (a CCKA-receptor antagonist) and CR2945 (a CCKB-receptor antagonist). Conclusion CCK-8 inhibits IL-1?-induced RSC-364 proliferation, probably by reducing p38MAPK activity through CCKA and CCKB receptors.
