Feature extraction is a very crucial step in P300-based brain-computer interface (BCI) and independent component analysis (ICA) is a suitable P300 feature extraction method. But at present the convergence performance of the general ICA iteration methods are not very satisfactory. In this paper, a method based on quantum particle swarm optimizer (QPSO) algorithm and ICA technique is put forward for P300 extraction. In this method, quantum computing is used to impel ICA iteration to globally converge faster. It achieved the purpose of extracting P300 rapidly and efficiently. The method was tested on two public datasets of BCI Competition II and III, and a simple linear classifier was employed to classify the extracted P300 features. The recognition accuracy reached 94.4% with 15 times averaged. The results showed that the proposed method could extract P300 rapidly and the extraction effect did not reduce. It provides an experimental basis for further study of real-time BCI system.

The therapeutic effect of anti-vascular endothelial growth factor (VEGF) for neovascular age-related macular degeneration (nAMD) was determined by a number of factors.Comprehensive thorough analysis of clinical features,imaging results and treatment response can predict the potential efficacy and possible vision recovery for the patient,and also can optimize the treatment regime to make a personalized therapy plan.Precise medicine with data from genomics,proteomics and metabolomics study will provide more objective and accurate biology basis for individual precise treatment.The future research should focus on comprehensive assessment of factors affecting the efficacy of anti-VEGF therapy,to achieve individualized precise diagnosis and treatment,to improve the therapeutic outcome of nAMD.

Uveitis is a kind of refractory blinding eye diseases.Noninfectious uveitis is an important part of uveitis,which is thought to be an autoimmune disease,and systemic immunosuppressive therapy is usually required to prevent visual loss.As a selective T-cell inhibitor,cyclosporine A is one of the most widely used immunosuppressants,and has obvious therapeutic effect on many kinds of uveitis.Cyclosporine A combined with glucocorticoid,other immunosuppressants or biological agents can improve the therapeutic effect and reduce the side effects.Recently,the inhibitory effect on glucocorticoid-resistant Th17 cells and topical application of cyclosporine A,show its advantage and potential in the treatment of noninfectious uveitis.

Objective To investigate the clinical diagnosis and treatment of incomplete Beh et′s disease. Methods The clinical data of 52 patients (83 eyes ) with incomplete Beh et′s disease were retrospectively analysed. Visual acuity and results of examination of slit-lamp microscope, ocular fundus, and fundus fluorescein angiography (FFA) were observed and analysed. All of patients were treated by local cycloplegic, systemic treatment with glucocorticoid and cytoxan. The followed-up period was 1 year or more. Results Recurrent hypopyon or empyema of anterior chamber angle, and hyperaemia of optic papilla was found in 54 and 41 eyes, respectively. The results of FFA showed that abnormal changes were found in all of the eyes. There was vascular leakage and staining of optic papilla at the early and late stage in 83 eyes (100%), diffuse leakage of retinal capillary vessel in 83 eyes (100%), and leakage of affected branch of retinal vessel and staining of the vascular wall at the late stage in 71 eyes (85.54%).After the treatment, the disease recovered completely in 20 patients (26 eyes), recovered partly in 20 (33 eyes), and alleviated in 12 (24 eyes). No patients suffered from hypopyon or empyema of anterior chamber angle and hyperemia of optic papilla. None of the patients had oral ulcer, genital ulcer or arthritis until the last day of the follow-up. Conclusions Recurrent hypopyon, papillitis, and retinal vasculitis were the main clinical manifestations of incomplete Beh et′s disease. FFA redounds to the diagnosis of the disease and timely application of cycloplegic and systemic application of glucocorticoid and cytoxan may inhibit the aggravation of the disease effectively.

60 mm Hg (PP1 group) or 40 mm Hg≤PP≤60 mm Hg (PP2 group),1 mm Hg =0.133 kPa.Ambulatory blood pressure monitoring,the serum and urine ?_2-MG,urine mAlb,blood BUN and Cr were measured in both groups,the blood pressure,serum and urine ?_2-MG,urine mAlb,blood BUN and Cr were compared between two groups. Results Compared with PP2 group,the PP1 group showed higher levels of renal function indexes. Conclusion Renal damage is related with pulse pressure in senile essential hypertension.

Further study of the effect of monosodium glutamate on body temperature using rabbits as experimental model by repeatedly intravenous injection of MSG. The experimental results showed that the body temperature of rabbits were decreased significantly at a time of each day consecutively for three days with medium dose MSG(0.5g/kg/day) However, this effect was disappeared following the fourth administration of MSG a week later, and so did the fifth administration of MSG two weeks later. Those results suggested that the disappearance of decreased body temperature by MSG may be due to tolerance development after MSG was administrated repeatedly. The authors proposed two hypotheses of mechanisms for the development of MSG"tolerance". which would be investigated further.

Objective: To observe the therapeutic effect of treating senile intervertebral disc Herniation with acupuncture, tuina and traction and with physiotherapy and traction. Methods: Altogether 150 cases above 65 years old were randomly allocated into treatment group and control group, each containing 75 cases. Traction, acupuncture and tuina therapy were adopted in the treatment group, while traction and physiotherapy were adopted in the control group. Results: After one-month treatment, the recovery rate of the treatment group were 70.7%, which was significantly better than 53.3% of the control group (P＜ 0.05). Conclusion:Combination of acupuncture, tuina and traction has very good efficacy in treating senile intervertebral disc Herniation.

Objective:To observe the efficacy of acupuncture-moxibustion therapy in treating urinary retention after surgery for cervical cancer. Methods:Fifty eligible patients were randomized into a treatment group and a control group by their visiting sequence, 25 in each group. The control group was intervened by indwelling urethral catheter after gynecological surgery; while the treatment group started to receive acupuncture-moxibustion and cupping treatment at the 7th day after surgery, in addition to the intervention given to the control group. The residual urine volume and total effective rate of the two groups were detected. Results:After 7-day treatments, the total effective rate was 92.0% in the treatment group versus 72.0% in the control group, and the difference was statistically significant (P<0.05). Conclusion:Acupuncture-moxibustion treatment plus cupping based on the conventional intervention is effective for urinary retention after surgery for cervical cancer, worth promoting in clinic.

Objective To investigate the clinical effect of plastic surgery of double-palpebra with reposition of lacrimal gland for blepharochalasis.Methods We operated on 10 cases (20 eyes) with dermatolysis palpebrarum which stopped attack and was static for more than one year.A double eyelid fold incision was made.Then redundant skin and sphincter palpebrarum as well as protrusion of intraorbital fat were removed.In the operation of dislocation of lacrmial gland we sewed up lacrmial gland in full thickness and fixed it to the periosteum of lacrmial fossa,and the levator muscle of upper eye lid aponeurosis prothesis or plication was choosed when the levator muscle of upper eye lid aponeurosis was broken or not.And for the shorted transverse diameter of coloboma of eye lid we sewed up the external palpebral ligament and fixed it to the periosteum of lateral orbital margin.Results All the 10 patients got satisfactory therapeutic effect,the cutis laxa had been amended obviously,the good upper double eyelid shape could be achieved,the reposition of lacrimal gland was finished,lapsus palpebrae superioris and shorted transverse diameter of coloboma of eye lid had been rectified satisfactorily.All cases we followed up for three monthes to one year,and dislocation of lacrmial gland had been amended in one case,others had been reposited well,without recurrence.Conclusions Blepharochalasis can be effectively treated by surgery,and it is convenient and effective to treat dislocation of lacrimal gland and blepharochalasis through a double eyelid fold incision.This multiple surgical treatment is not only a curative operation but also a cosmetic surgery.
