Objective To evaluate the efficacy of comprehensive rehabilitation on cervical syndrome(CS).Methods 112 patients with CS were randomly divided into two groups.The cases in comprehensive rehabilitation group(n=56) were treated with traction,ultrashort wave and massage,while those in the control group(n=56) were treated with traction only.Results The efficient rate of comprehensive group were 91.1% 3 weeks after treatment,and the symptom scores improved significantly compared with the control group(P<0.01).Conclusion The comprehensive rehabilitation is efficient on cervical syndrome with few side-effects and complication.

Objective To compare the effects of stimulated ischemic preconditioning (IP) and ischemia/reperfusion (I/R) on the hyperpolarization-activated current (I_ f ) of sinoatrial node cells and explore the mechanisms of electrophysiological protection of IP. Methods The sinoatrial node cells cultured for 2 d were randomized to three groups: ① Control in which the cells were cultured at 37 ℃ in the mimic reperfusion solution, meanwhile the mixture of 95% O_ 2 and 5% N_ 2 was ventilated; ② I/R in which the cells were cultured in the mimic ischemic solution and simultaneously the mixture of 95% O_ 2 and 5% N_ 2 was ventilated for 3 h, then cultured in the mimic reperfusion solution and simultaneously the mixture of 95% O_ 2 and 5% N_ 2 was ventilated for 4 h; ③ IP in which the cells underwent ischemia for 10 min and reperfusion for 10 min, repeated once. Then the cells were treated as the same as the I/R group. After 4-hour reperfusion, I_ f was recorded by whole-cell patch clamp technology. Results I/R significantly enhanced the current density of I_ f , shifted the current activation curve to more positive value by changing the half-activation voltage from (-98.9?2.4) mV to (-85.2?2.5) mV (P

Objective To compare the effects of different ischemic preconditioning (IP) protocols on the viability of primary cultured sinoatrial node cells from neonatal rats for investigating the protective effect of IP. Methods The cells were randomized into eleven groups: control, ischemia/reperfusion (I/R), IP1 (preconditioned with ischemia/reperfusion for 5 min), IP2 (preconditioned with 2 cycles of ischemia/ reperfusion for 5 min), IP3 (preconditioned with 3 cycles of ischemia/reperfusion for 5 min), IP4 (preconditioned with ischemia/reperfusion for 10 min), IP5 (preconditioned with 2 cycles of ischemia/reperfusion for 10 min), IP6 (preconditioned with 3 cycles of ischemia/reperfusion for 10 min), IP7 (preconditioned with ischemia/reperfusion for 20 min), IP8 (preconditioned with 2 cycles of ischemia/reperfusion for 20 min), and IP9 (preconditioned with 3 cycles of ischemia/reperfusion for 20 min). PI positive staining rate and changes of D 490 after 3 h ischemia/4 h reperfusion were determined by PI staining and MTT chromatometry. Results ① D 490 value in sinoatrial node cells in each experimental group was significantly lower than that in the control group, but that in IP2, IP3, IP4, IP5, and IP7 groups was significantly higher than that in I/R group (P

Objective To study the effects of mimic ischemic preconditioning (IP) on i and I-LCa of sinoatrial node cells and explore the protective effects of IP. Methods Cells were randomized to three groups: control, ischemia/reperfusion (I/R), IP. After labeled with fura4, fluorescence intensity of i was studied with laser confocal microscopy and I-LCa was recorded by whole-cell patch clamp technology. Results IP significantly reduced the fluorescence intensity of i and enhanced the peak of I-LCa as compared with I/R, shifted the I-V curve to more negative value. Conclusion IP can reduce the overload of i caused by I/R and increase I-LCa weakened by I/R.

F-actin, vinculin, ?-tubulin and desmin were studied with laser confocal microscopy after labled with different immune fluorescent agents. RESULTS: Compared with control, although both H/R and HP reduced the fluorescence intensity of these four cytoskeletal proteins remarkably (P

Objective To analyze serum levels of C1q in children with nephrotic syndrome (NS),and investigate the clinical significance and the relationship among the altered serum C1q levels and other lipid/lipoprotein and renal function parametersin children with NS inacute and remission phases.Methods Serum levels of C1q were measured in 78 NS children with acute phase,in 64NS children with remission and in 77 healthy control children.The other lipid/lipoprotein and renal function parameters were also analyzed in these children,including TP,ALB,TC,TG,LDL-C,HDL-C,Urea,Cr and Uric.Results Compared with the healthy control children [173.00(161.00～185.00)mg/L],children with NS inacute [203.50(183.75 ～ 223.75) mg/L] and remission phases [185.00 (161.00 ～ 202.00) mg/L] all had a significantly increasedserum levels of C1q.Compared with NS children in remission,those in acute phase showed a significantly increased C1q (P＜0.001).In all the NS children,the serum levels of C1q were positively correlated with the levels of TC (r=0.483,P＜0.001),TG (r=0.423,P＜0.001) and LDL-C (r=0.450,P＜0.001),while negatively correlated with the levels of TP (r=-0.276,P=0.001 ＜0.01) and ALB (r=-0.410,P＜0.001).Multiple linear regression analyses showed that serum levels of C1q were independently associated with serum TG levels (β=9.235,P＜0.001;adjusted R2 =0.215) after adjustment of other related factors.Conclusion Serum levels of C1q were significantly increased in NS children in association with their conditions and the levels of lipid/lipoprotein parameters,and may be function as anovel parameter for assessing the development of NS.

OBJECTIVE: To assess the efficacy and safety of glucocorticoid in initial treatment of sudden hearing loss with intratympanic (IT) and systemic ways. METHOD: We searched the database of PubMed, Cochrane, Embase,CBM, CNKI, VIP, Wanfang systematically. Literatures were screened according to the preestablished inclusion and exclusion standards,and all the RCT literatures associated with intratympanic and systemic glucocorticoid in the initial treatment of sudden hearing loss before may 2015 were collected. All the data, which meet the inclusion standards, were analyzed by using Meta-analysis software. RESULT: Among all the qualified literatures, 11 randomized controlled trials were included. A total of 1298 cases were involved, including 521 cases with intratympanic administration, 410 with IV-therapy, and 201 with oral therapy. Meta analysis results showed that there was significant difference of the total effective rate and improvement rate between the intratympanic and systemic administration. Intratympanic injection (P > 0.05) was more effective than systemic administration. There was no significant difference between intratympanic group and oral group (RR = 1.15, 95% CI: 0.92-1.42, P > 0.05). A significant difference of the effective rate occurred between intratympanic group and IV therapy group (RR = 1.17, 95% CI: 1.02-1.34, P < 0.05). The major complications of intratympanic were pain, dizziness/vertigo, which occurred more frequently than systemic therapy group; The major complications of systemic therapy group were hyperglycaemia, loss of appetite and insomnia. CONCLUSION This study shows that the intratympanic (IT) glucocorticoid for sudden deafness is more effective than the systemic administration. But it was not the first choice in clinical treatment. Further studies are warranted.

Atropine is one of the useful methods that can slow down myopia progression.The effect of atropine has been proved by clinical researches, among which, various concentrations of atropine from 0.01% to 1% are all effective on control myopia progression for children, and atropine 0.01% has been verified to have the best balance between efficiency and side effects.Though many hypotheses and theories have been proposed to explain the mechanism of atropine, no community agreement has been reached among global scientists.Researches have shown that the possible receptors of atropine include M1-M5 acetylcholine families, γ-aminobutyric acid (GABA) receptors, dopamine receptors, ZENK gene and α 2-adrenergic receptors, which are located on retina and posterior sclera.The inhibitory effect of atropine on myopia progression might be achieved through cholinergic, G-protein and GABA signaling pathway.The target site of action of atropine is located on retinal pigment epithelium, choroid and scleral collagen.The effects of topical application of atropine combined with orthokeratology are better than wearing orthokeratology only.The mechanism, site of action and most relevant clinical researches of atropine of various concentrations were reviewed in this article.

Objective To evaluate the therapeutic efficacy and safety of transcatheter closure of atrial septal defect (ASD) and patent ductus arteriosus (PDA) using Amplatzer occluder. Methods Routine cardiac catheterization and angiography were performed in 50 patients (23 male, 27 female, age ranging from 3 to 64 years old), including 19 cases of ASD and 31 cases of PDA under local or general anesthesia. After balloon sizing of the ASD, the optimal Amplazter septal occluder (ASO) was transmitted into the left atrial, and the left and right disks were released in turn. The Amplatzer occluder was completely released after transthoracic echocardiography confirmed that there was no residual shunts or new onset mitral valve regurgitation. The Amplatzer duct occluder (ADO) size was selected according to the narrowest point of PDA measured by angiography, and the occluder was released after the repeated angiography showed no residual shunts. Results ① The mean diameter of the ASD measured by balloon was 13-31 (23?6) mm and the diameter of ASO was (17-40) mm. The immediate closure rate was 100%. ② Angiography confirmed that closure of the ductus using ADO was achieved in 30 patients, and closure of the large size (12 mm) was achieved in 1 case of PDA patient using ASO (17 mm). No complications were encountered. Conclusion Transcatheter closure of ASD and PDA using Amplatzer device, with the advantages of simple operation, confirmative occlusion efficacy, minimal invasiveness, wide indications, and less complications, has a bright future of clinical application.

Objective To investigate the effect of folic acid intervention on plasma homocysteine (Hcy) metabolic changes and pulse wave velocity(PWV)in patients with type H hypertension. Methods Patients(hos-pitalized from March 2014 to December in our hospital)with H type hypertension were randomly divided into treat-ment group and control group randomly ,and were given routine antihypertensive drug therapy. Treatment group was given oral folic acid 0.8 mg,1 times a day,the control group was given placebo,1 times a day. All patient were treated for 12 months. Changes of plasma Hcy and PWV levels were observed. Results 432 patients(Han nationality)with type H hypertension were enrolled in this study with the age of 61.7 ± 13.6 years old and the ratio of men and women is 1.3:1. The most common diseases were coronary heart disease and type 2 diabetes mellitus. 2 groups were treated for a period of 12 months,with follow-up time from 6 to 10 months(average duration in 8 months). After treatment,the difference between plasma Hcy(Z=-7.63,P=0.000)and PWV(Z=-3.16,P=0.002)levels of the two groups were statistically significant. Conclusion Folic acid intervention can significantly reduce the level of plasma Hcy in patients with type H hypertension ,slow down the progression of atherosclerosis and reduce the risk factors of cardiovascular disease.
