AIM: To investigate the early changes of retinal function in diabetic patients detected by multifocal electroretinogram (mfERG).METHODS: The first-order kernel responses of mfERG were recorded from eyes of 33 normal control subjects,63 diabetic patients without retinopathy and 43 diabetic patients with background retinopathy. The response densities and implicit times of N1 and P1 were compared among the control, diabetic patients without retinopathy and diabetic patients with retinopathy.RESULTS: The response densities of N1 and P1 in central 3 rings were reduced significantly in diabetic eyes with and without retinopathy. And the implicit times of N1 and P1 were delayed significantly only in diabetic eyes with retinopathy.CONCLUSION: mfERG can detect the early changes of retinal function quantitatively in diabetic patients. Analysis of response densities and implicit times of N1 and P1 can reflect the progress of local retinal dysfunction in diabetes.

The suspended magnetic moxibustion cupping therapy,as a specific moxibustion method which collects moxibustion,cupping,infrared and magnetic therapy into one,and integrates with the warming and heating effect of moxibustion,sucking effect of cups,and effect of infrared light energy and magnetic energy,is a particularly unique method for weight loss.This article introduces the basic situation and mechanism of suspended magnetic cupping therapy for weight loss.For pathogenesis of deficiency,phlegm,stagnation and cold in obesity,Shuang Long Xi Zhu (two dragons playing a ball) moxibustion,abdominal Jiu Gong (nine palaces) moxibustion,San Yang Kai Tai (auspicious beginning) moxibustion and Chang Long (long dragon) moxibustion were given respectively.This therapy has inspired the clinical idea of Chinese medicine for obesity.

Objective This paper summarize peri-operative nursing of minimally invasive surgery on osteoradionecrosis of skull base after radiotherapy for nasopharyngeal carcinoma.Methods 47 cases of osteoradionecrosis of skull base after radiotherapy for nasopharyngeal carcinoma were operated via nasal endoscope from March 2006 to March 2013.Focused peri-operative psychological support and adequate medical care were given to patients.Strengthened nasal nasopharyngeal cavity nursing,the observation and nursing of complications were carried out after operation and health guidance pre-discharge was given.Results The operations of 47 cases were successful and no major complication of intra-operation and post-operation occurred.Headache and foul odor relieved after operation.The follow-up continued for 3 to 84 months,46 cases were survived,1 case died of nasopharyngeal massive bleeding.Conclusions Effective peri-operative nursing of minimally invasive surgery on osteoradionecrosis of skull base after radiotherapy could ensure patients' cooperation and the smooth implementation of surgery and improve the quality of life.

ObjectiveTo compare the safety and efficacy of combined thrombolysis and systemic anticoagulation therapy for the treatment of cerebral venous and sinus thrombosis (CVST).MethodsA retrospective review of consecutive inpatients with CVST was undertaken. Patients were divided into two groups,combined thrombolysis group (CTG) and systemic anticoagulation group (SAG).CTG underwent improved thrombolysis scheme which included mechanical thrombus maceration and unremitting microdosis urokinase injection into the venous sinus besides low molecular weight heparin anticoagulation.Neurological deficits before and after treatment were graded with the National Institute of Health Stroke Scale (NIHSS).Functional outcomes at discharge were graded on the modified Rankin Scale (mRS).ResultsThere were 30 cases in CTG ( male =9) and 86 cases in SAG ( male =23 ).There was no significant difference of neurological deficits before treatment between two groups(0-19 vs 0-17,Z =-0.474,P =0.636).After treatment,NIHSS and mRS at discharge were significantly decreased in CTG compared to SAG.There was no significant difference on the incidence of intracerebral hemorrhage.Conclusions Combined thrombolysis is better than systemic anticoagulation in improving neurological function.Combined thrombolysis does not increase incidence of ICH compared to systemic anticoagulation.

Objective:To investigate the influence of B-lymphocyte chemoattractant on the immune response of CVB3 fusion gene vaccine pcDNA3/C3d3-sVP1.Methods:BALB/c mice were divided into 4 groups randomly, and injected intramuscularly with pcDNA3,pcDNA3/BLC,pcDNA3/C3d3-sVP1 and the combination with the plasmid pcDNA3/BLC and pcDNA3/C3d3-sVP1.At a certain time,they were measured for the titers for neutralizing antibodies,specific CTL cytotoxic activity.The protective efficacy of DNA vaccinations was evaluated by titers of blood viruses and survival rate.Results:The titers for antibodies increased with the time of inoculation.More specifically,the antibody titers (42.17±1.43) and the specific CTL cytotoxic activity (41.3%±3.51%) of the mice in the combination group were remarkably stronger than in the mice with pcDNA3/C3d3-sVP1(P＜0.05),but the virus titers of blood was lower.After lethal CVB3 challenge,the protection of mice from death in the combination group with the plasmid pcDNA3/BLC and pcDNA3/C3d3-sVP1 was 44%.Survival curves indicated that the survive state of combination group was better than others.Conclusion:BLC can strongly enhance the specific immunity induced by C3d3-sVP1.

A resonance light scattering(RLS) method for the determination of critical micelle concentration(CMC) of sodium dodecyl benzene sulfonate(SDBS) was proposed. Under room temperature, the RLS intensity of the SDBS system increased with increasing SDBS concentration. And when the concentration of SDBS approached CMC, the RLS intensity had increased sharply. The RLS peaks were appeared at 330 nm and 396 nm, respectively. The plot of the RLS intensity at 396 nm versus SDBS concentration was S-Curve. The concentration of SDBS at the intersection point of two tangents to S-curve was considered as SBDS CMC. This result was consistent with the results of the pyrene probe fluorescence spectrometry and electrical conductivity method. The influences of the concentration of Ca2+ on the aggregation behave of SDBS and SDBS-emulsion OP(OP) systems were studied by the RLS method. The results indicated that the mixed

AlM: To observe retinal hemodynamic influence of compound xueshuantong capsule on nonproliferative diabetic retinopathy ( NPDR) after laser photocoagulation.METHODS:A total of 41 patients (72 eyes) with NPDR after laser photocoagulation were enrolled in this study. They were all given compound xueshuantong capsule, and used color Doppler flow imaging for detection of retinal hemodynamics.
RESULTS: After treatment, patients with retinal blood perfusion significantly improved; central retinal arterial peak systolic velocity ( PSV ) , end - diastolic velocity (EDV) and medial velocity (Vm) were increased, while the resistance index ( Rl) decreased. The difference have statistical significance (P<0. 05). The visual acuity of 61 eyes improved, efficiency was 85%. Visual acuity was related with PSV, Vm and Rl.
CONCLUSlON: Compound xueshuantong capsule can improve retinal blood perfusion for nonproliferative diabetic retinopathy after laser photocoagulation, which is related to improvement of visual prognosis.
