Objective To explore electrophysiological features of infantile spinal muscular atrophy (SMA), and to evaluate diagnostic value of electrophysiological examinations in patients with SMA.Methods Tweenty-seven SMA children from Jan 2011 to Nov 2015 diagnosed in Wuxi People''s Hospital were enralled.All patients had neurogenic changes by EMG and finally confirmed by genetic test as SMA.Basic clinical data were retrospectively analyzed.Nerve conduction velocity was tested in each patient;While EMG was performed in no less than six muscles in each patient.Results All these patients were characterized by progressive flaccid paralysis in limbs.In all cases, amplitude of CMAP in median nerve was significantly decreased, apparent decreased in ulnar nerve and peroneal nerve;while mild decrease of MCV was appeared in ulnar nerve.Nothing abnormal were detected in sensory nerve conduction.EMG demonstrated neurogenic damage.Conclusion Typical clinical symptoms of infantile SMA are progressive symmetrical loss of muscle control and atrophy in limbs, and specificity electrophysiological representation provides very important basis for the diagnosis.

Medical community and pharmaceutical companies are currently facing a dire need for discovery and identification of new druggable targets. However, the discovery of small-molecule target is an important and arduous task for the biological and medical scientists. To overcome the bottlenecks for target validation, many new approaches are being developed, such as chemical proteomics. As a part of proteomics approaches, chemical proteomics employs small-molecule compounds that can specifically interact with the target protein to interfere with and detect proteomics. Therefore, new target identification, drug discovery and research on multi-target-directed drugs will all be benefited from the further advances in chemical proteomics approaches. Chemical proteomics has the potential to greatly enhance the efficiency of the drug discovery process.

Objective To explore the feasibility and advantage of the small figure-L unilateral transternal incision for the treatment of anteri or mediastinal tumor. Methods Twenty-four patients with anteri or mediastinal tumor were enrolled in the study. Under general anesthesia, after a 6 to 10 cm midline skin incision was made, a unilateral figure-L partial ste rnotomy on the side occupied by the tumor was made in the second or third interc ostals space, taking into account the tumor size and location. Tumors were resec ted with excellent exposure. Results All tumors were completely resected during the operation. In 8 cases, tumors encroached on the adjacent lu ng tissue, and lung tissue was partially resected. In 6 cases, tumors invaded th e pericardium, and the pericardium was partially removed. Mean operating time wa s 106 minutes (80~125 minutes). The mean time of hospital stay was 5 days after the operation, and there was no complication. All patients were alive with a mea n follow-up period of 14 months (3~24 months). Conclusion The figure-L unilateral mini-sternotomy is considered as an effective and useful mi nimally invasive approach for anterior mediastinal tumors.

Objective To explore how the different intervention measures affect the outcome of central venous catheter-related thrombosis (CRT) in children. Methods A retrospective analysis was carried out to collect the clinical data of patients with CRT from the nursing management system of the Children′s Hospital Affiliated to Zhejiang University School of Medicine which reported by each nursing unit from January 1,2015 to December 31,2015. Results Totally 108 cases were included (72 boys and 36 girls), median age of 24.5 months (ranged from 1 month to 14 years old). Nearly 42.59% (46/108) patients suffered from neurological diseases. Nearly 55.56%(60/108) CRT was detected in the first week after catheterization. Once CRT conformed, there were four kinds clinical intervention options applied. Intervention 1: thrombolytic therapy with urokinase combined anticoagulation with nadroparin calcium. Intervention 2: anticoagulant therapy only. Intervention 3: thrombolytic therapy alone. Intervention 4: no medications. The differences of effective between the four kinds of intervention were statistically significant (χ2=13.380, P=0.004). The single-factor regression analysis was done to each relevant factor. Finally the multivariate regression analysis showed four factors had impacts upon the results. The factors were as follows:gender (OR=10.400, 95%CI 1.879-57.563, P=0.007);interval (OR=1.107, 95%CI 1.035-1.184, P = 0.003), size of thrombus(OR = 1.562,95%CI 1.033-2.362,P=0.035; Intervention 2 (OR =11.757, 95% CI 2.254- 61.327, P = 0.003), intervention 4 (OR = 35.397, 95% CI 3.493-358.760, P =0.003). Conclusions The earlier and small size thrombus is more soluble. Thrombolytic therapy or combined anticoagulation is more effective. It is recommended that if no contraindications presents, thrombolytic combined with anticoagulant therapy should start early standardized treatment.

Aflibercept is a soluble fusion protein which combines ligand-binding elements taken from the extracellular components of vascular endothelial growth factor (VEGF) receptor-1 and receptor-2 fused to the Fc portion of IgG,and it is a novel antiVEGF drug,which can reduce vascular permeability and inhibit neoangiogenesis by binding VEGF tightly.A large number of phase Ⅲ clinical trials have demonstrated the satisfactory outcomes of aflibercept in the management of neovascular age-related macular degeneration,macular edema secondary to retinal vein occlusion or macular edema and other retinal vascular diseases.Moreover,intravitreal injection of afiibercept can improve the visual acuity and attenuate the fundus lesion,which provides a new drug option for physicians.The review will summarize the chemical properties of aflibercept and its application,safety and efficacy of aflibercept for the treatment of retinal vascular diseases.

Objective To compare the efficacy and adverse reactions of intensity-modulated radiation therapy (IMRT) and conventional pelvic field radiation therapy for middle and advanced cervical cancer. Methods A total of 144 patients with stageⅡB-ⅢB cervical cancer from October 2007 to September 2012 were divided into IMRT group (72 cases), and routine radiotherapy group (72 cases) by using random number table method. The IMRT group was exposed to the 6 MV-X line 7 field, a dose of 46-50 Gy for planning target volume (PTV), 54-60 Gy for gross tumor volume (GTVnd) simultaneously integrated boosted, in 25-28 fractions. The central block of lead 4 cm was changed to 4 fields irradiation, adding to 46-54 Gy for the conventional group after 30-40 Gy of the whole pelvic field. The total dose for the two groups of patients was 30-45 Gy, after completed 30 Gy in vitro exposure, to the cavity irradiation, 5-7 Gy/fraction, and synchronous cisplatin (DDP) sensitization chemotherapy was done synchronously. Results The recent complete remission, partial remission, overall survival ratio of two groups were compared respectively, and the difference was not statistically significant (P > 0.05). The difference in 1 year survival rate of IMRT group and routine radiotherapy group was not statistically significant (χ2= 1.455, P> 0.05). The difference in 3 and 5 year survival rate was statistically significant [76.4 % (55/72) vs. 59.7 % (43/72); 72.2 % (52/72) vs. 55.6 %(40/72), P< 0.05]. Acute radiotherapy major adverse reactions included the digestive system, urinary system, skin response and haematological toxicity (bone marrow suppression). The incidence and degree of skin response in IMRT group was lower than that in routine radiotherapy group (P<0.05). The adverse effects of late radiotherapy were mainly rectal, bladder, skin response and hematological toxicity (bone marrow suppression). The incidence rectal and skin response in IMRT group was lower than that in routine radiotherapy group (P< 0.05). Conclusion The IMRT can improve the survival rate of advanced cervical cancer patients for 3-5 years, reduce the adverse effects of acute and terminal radiotherapy, and improve the quality of life.
