OBJECTIVETo investigate effects of elastic stable intramedullary nails for the treatment of radial neck fracture in children.

METHODSFrom July 2006 to December 2011, 25 children with radical neck fractures, which included 16 males and 9 females aged from 7 to 15 years old (means 10.7), were treated with elastic stable intramedullary nails. According to Judet classification, 6 cases were type II, 17 cases were type III and 2 cases were type IV (including 1 case with type IVa and 1 case with type IVb). The fracture healing, pain, deformity and range of motion of elbow were recorded.

RESULTSAll patients were followed up for 6 to 24 months with an average of 14 months. Twenty-five patients were obtained bone healing. According to Tibone and Stoltz evaluation standard, 18 cases got excellet results, 4 cases in good and 3 cases in moderate.

CONCLUSIONElastic stable intramedullary nails for the treatment of radial neck fracture in children has advantages of simple operation,less trauma and good results.

OBJECTIVETo explore therapeutic effects of Modified pinning combined with external tension band for the treatment of Gartland type III humeral supracondylar fractures in children.

METHODSFrom February 2009 to November 2010, 79 children with Gartland type III humeral supracondylar fractures were treated by modified pinning (pinning cross internal and external condyle assisted with lateral condyle) combined with external tension band (crossing needle end and hooking around) through lateral approach of elbow. There were 47 males and 32 females, with an average age of 8.7 years (ranging from 2.5 to 14 years). The time from injury to operation was 2 h to 8 d. The elbow joint function and Carrying angle were observed before and after treatment. The Flynn criteria were used to evaluate therapeutic effects.

RESULTSSixty-one patients were followed up (18 patients' data were lost) for 6-30 months (mean 13.5 months). According to Flynn criteria, 53 patients got excellent result, 7 good and 1 fair.

CONCLUSIONTreatment of child Gartland type III humeral supracondylar fractures with modified pinning combined with external tension band through lateral approach of elbow is believed to be an ideal method, which has advantages of reliable fixation, rapid recovery and less complications.

AIM: To elucidate molecular mechanisms underlying calcium handling protein in diastolic heart failure (DHF) from mRNA level and protein expression, including calcium adenosine triphosphatase (Ca 2+ -ATPase), phospholamban, ryanodine receptor, calsequestrin and L-type calcium channel. METHODS: The mRNA of these calcium handling genes were detected by RT-PCR, and the protein levels were analyzed by Western blot analysis. RESULTS: Compared with sham-operated rabbits, the steady-state levels of mRNA encoding the SR Ca 2+ -ATPase and cardiac L-type calcium channel were decreased significantly in rabbits with DHF, and protein level of SR Ca 2+ - ATPase was greatly reduced, whereas the mRNA and protein levels of other calcium handling protein were unchanged. CONCLUSION: L-type calcium channel and the sarcoplasmic reticular Ca 2+ -ATPase were down regulated in DHF. These changes may be a contributory factor for DHF.

Objective To investigate the effect and mechanism of sphingosine 1-phosphate(S1P)on action potential(AP)and voltage-dependent potassium current(KV)in isolated guinea pig ventricular myocytes.Methods The ventricular myocytes were isolated by using Langendorff perfusion method.The AP and KV were recorded by whole cell patch-clamp recording technique.Results S1P prolonged the 50% and 90% action potential duration(APD50 and APD90)and decreased KV which were blocked by pertussis toxin(PTX)or Calphostin C.Conclusion S1P decreased KV in a PKC pathway and prolonged action potential duration in guinea-pig ventricular myocytes.

Construction of the network course is one of the hot spots of teaching reform. With medical preparations for military struggle and the continuous improvement of dealing with unexpected natural disasters,the department of ophthalmology analyzed the characteristics,status and the advantages of network teaching of the"eye injury"carefully,to proceed with network cur-riculum reform. Teaching is designed through specific goals,processes,content,organization and development environment,and the other aspects.

AlM:To evaluate the efficacy of combined pranoprofen eye drops and artificial tears on the treatment of mild to moderate dry eye syndrome after trabbeculectomy.METHODS:This prospective case control study included 63 cases (63 eyes) of patients with mild to moderate dry eye syndrome after trabbeculectomy in our hospital from November 2013 to June 2013. All subjects were randomly divided into two groups. Observation group was treated with combined pranoprofen eye drops and artificial tears and control group received simple artificial tears marking the eyes at 1, 2, 4wk. The patient's symptoms, signs, BUT, S▏t, and FL were observed before treatment and 1, 2, 4wk after treatment.RESULTS: After 2wk, the symptoms of observation group were improved, there was statistically significant difference (P<0. 05). FL difference of each group was statistically significant ( P<0. 05 ); After 4wk, symptoms and signs were improved. There was statistically significant difference ( P < 0. 05 ). The BUT of the observation group and corneal FL scores of two groups showed significant differences (P<0. 05). CONCLUSlON: Artificial tears joint pranoprofen eye drops has good curative effect in the treatment of mild to moderate dry eye syndrome after trabbeculectomy.

Objective To study the clinical value of portable echocardiography system in diagnosis for acute paroxysmal dyspnea.Methods Clinical data of 81 patients with acute paroxysmal dyspnea recorded by a portable echocardiography apparatus at their bedside were retrospectively analyzed,and compared to those of 45 patients by conventional echocardiography.Results The 2D images in portable echocardiograph were similar to those of conventional echocardiograph.Diagnosis could be established in 74 (91.4%),corrected in six (7.4%) and not confirmed only in one (1.2%) of 81 patients with acute paroxysmal dyspnea by portable echocardiography system.And,portable echocardiography system could be used to diagnose pericardial effusion and to monitor perieardial puncturing and draining at bedside. Conclusions Portable echocardiography systems can provide rapid,accurate and valuable information on diagnosis and treatment for acute paroxysmal dyspnea,and make its clinical intervention accurate,scientific and effective,bringing echocardiography performed at bedside possible.
