Choroidal metastasis is one of the most common malignant tumors inside the eyes. It causes pain, hypopsia and some other related symptoms. It reduces the quality of the patients' life. It's significant for the patients to be detected and treated early, therefore they will have better vision and longer life. The treatments of choroidal metastasis are developing quickly. Both the vitreous cavity injection of targeted drug and gene therapy are hot topics of research. This paper summarizes the etiology, development, diagnosis and treatment of choroidal metastasis nowadays.

? AIM: To analyze clinical characteristics and postoperative outcomes after open globe injury.?METHODS: Demographic characteristics ( age, gender, eye trauma, profession, cause of injury and injured part ) , as well as complications and prognosis were analyzed in 152 cases (152 eyes) of open globe injury.? RESULTS: Patients with open globe injury had an average age of 40. 45±38. 32 years old with a 5. 9:1 male-to-female gender ratio. The left-to-right eye ratio was 1. 27:1. Most patients were workers, farmers, or retired. The most common etiologies were scratches, boxing, and falls. Zone Ⅲ was the most commonly injured part. Iridoptosis or iris incarceration, retinal detachment, vitreal prolapse, hyphema or hypopyon, and vitreous hemorrhage were the most common complications. Visual acuity improved in 86 cases postoperatively but ophthalmectomy was still required in 25 eyes.?CONCLUSION: Vision can be improved after surgery in open globe injury. However, patients are usually seriously injured and improvement is minimal, thereby resulting in a great loss to patients and society.

Objective To investigate the application of the ultrasonic guidance-assisted neonatal internal jugular vein catheterization.Methods Sixty two newborns (including low birth weight infants) receving thoracic/abdominal operation or resection of malignant tumor on the body-surface were randomly assigned to ultrasound guidance (UG) group or surface mark landmark(S) group.Newborns in both groups were all punctured with 22G venous indwelling needles to place the external casing,followed by the steel wire guidance-assisted implantation of ARROW 4F dual chamber central venous catheter.Then we compared the rate of successful insertion attempt,rate of malpositioning,complications and average operation time between the two groups.Results The rate of successful insertion attempt was 96.8%(30/31) in the UG group,significantly higher than that in the S group (32.3%,10/31),there was significant difference between the two groups(χ2=28.182,P=0.000).Malpositioning happened in 2 cases in the UG group,but 25 cases in the S group.Rate of complications was higher in the S group compared to the UG group (64.5% vs 3.2%,χ2=25.99,P=0.000).Most importantly,the average operation time was (4.366±1.137)min in the UG group,significantly shorter than that of the S group [(13.70±5.34)min,t=5.463,P=0.028)].ConclusionUltrasound guidance-assisted catheterization for neonatal internal jugular vein is safe and feasible and can dramatically improve the success rate and prevent complications.

Objective To explore the safety of fat reduction treated by non invasive focused ultrasound.Methods A randomized double-blind and negative control clinical trial was carried out on the excess fat of 40 subjects' abdomen by a JCS-01 non-invasive focused ultrasound device.Subjects received treatments with the device on day 1 and day 7.Observations on the area treated and inquiries on feelings were conducted during treatments.Before the first treatment and 14 days after the treatment,laboratory examinations were performed,including liver function,blood lipid tests,etc.Results 40 subjects participated in the trial and 36 subjects (18 each in both treatment and control groups) accomplished 2 times of treatments,all followed-up and laboratory examinations.During the process of treatments,4 subjects in the experimental group complained about feelings of tepidity or pricking.One subject on blood test of triglyceride showed slightly higher than her early normal result,which fell to the normal level at reexamination.Conclusions Subjects treated by non-invasive focused ultrasound at the area of no more than 500 cm2 every time and at an interval of 6 days manifest little changes on the blood test results,with slightly local reactions but no complaints during follow-up.

Objective To investigate the selection and efficacy of operative medality for pancreatic transec-tion with major duct injury. Methods The clinical data were retrospectively analyzed in 21 patients with pancreatic disruption. They were treated in our hospital from Jan. 1995 to Feb. 2009. There were 14 males and 7 females in these cases with a mean age of 26 years (range 9-53 years). The trauma causes of them were blunt injuries in 13 and patent injuries in 8 cases. The injury grade (according to American Association for the Surgery of Trauma) distribution for these patients was grade Ⅲin 8 cases, grade Ⅳ in 8 cases, and grade V in 3. The early emergency operation was performed in eighteen within 12 hours, and delayed opera-tion was in three cases. Of these operative medalities, Roux-en-Y distal panereatojejunostomy was in 10 ca-ses, pancreatoduodenectomy was in 3, modified duodenal diverticulizatian was in 2, distal pancreatectomy was in 3, tube installing in major duct and external drainage, and suture of pancreatic section was in 2, su-ture of two broken sides in 1 (Roux-en-Y distal pancreatojejunostomy in second time). Results Twenty patients were cured, and one was died after a procedure of pancreatoduodenectomy. The postoperative pan-creatic fistula happened in 3 cases and recovered well with conservative line of management. Conclusions For improving the outcome of pancreatic transection, the earlier exploratory laparotomy and carrying out concept of "Damage Control Surgery" are critical. The individual operative modality based on the grade should be a-dopted in the surgical procedure.

Objective To summarize the experience in diagnosis and management for severe and complicated pancreatic trauma. Methods The clinical data of 21 patients with severe pancreatic trauma treated in our hospital were retrospectively analyzed. Of the 21 with a mean age of 26 (9-53), 14were male and 7 female. The causes of trauma were blunt injuries in 13 and patent injuries in 8 of them. The injury grade distribution for these patients was grade Ⅲ in 8 cases, grade Ⅳ in 8, and grade V in 3. The main diagnostic modalities included amylase measurement, ultrasonography, CT,endoscopic retrograde cholangiopancreatography (ERCP), and magnetic resonance cholangiopancreatography (MRCP) etc. All patients received surgical procedures. Roux-en-Y distal pancreatojejunostomy was performed in 10 patients, pancreatoduodenectomy in 3, modified duodenal diverticulization in 2, distal pancreatectomy in 3, tube installing in major duct and external drainage, and suture of pancreatic section in 2, and suture of two broken side respectively (delayed distal pancreatojejunostomy in the second time) in 1. Results Pancreatic injury was confirmed in 11 cases preoperatively and intraoperatively in the others. The early emergency operation was performed in 18 patients within 12hours, and delayed operation was done in 3 cases. Twenty patients were cured and 1 died after a procedure of pancreatoduodenectomy. The postoperative pancreatic fistula happened in 3 cases and recovered well with conservative line of management. Conclusion The diagnosis of severe and complicated pancreatic trauma is difficultly yet, so the earlier exploratory laparotomy should be suggested. The individual surgical modality based on the grade should be adopted in the operation and the concept of "Damage Control Surgery" should be carried out in the procedure. Extended operation should be avoided.

Objective To investigate the possible association between two single nucleotide polymorphisms (SNPs) loci of apolipoprotein E (ApoE) gene and epileptic drug resistance in a central Chinese Han population.Methods A case control study was performed in 364 epileptic patients.According to the criteria of drug resistant epilepsy proposed by International League Against Epilepsy in 2010,143 patients were classified into drug resistant group and 221 patients into drug responsive group.The peripheral venous blood of each patient was collected for DNA extraction after clinical evaluation.The candidate ApoE SNPs loci,including rs7412 and rs769450,were genotyped by BeadChip Scanning and GoldenGate Assay following the Illumina protocols.The differences in allelic and genotypic frequency were compared between groups.Linkage disequilibrium was calculated through SHEsis platform.Results There was no significant difference for genotype or allele of rs7412 between groups.The GG genotype (OR =2.038,95％ CI 1.196-3.475,P=0.009) and G allele (OR =1.618,95％CI 1.193-2.193,P=0.002) of rs7412 were significantly more abundant in the drug resistant group.As for idiopathic epileptic patients,the GG genotype (OR =2.110,95％ CI 1.189-3.744,P =0.011) and G allele (OR =1.641,95％ CI 1.187-2.270,P =0.003) of rs7412 were still significantly more abundant in the drug resistant group.There was no linkage disequilibrium between the two loci with D' value of 0.072.Conclusion The GG genotype and G allele of ApoE rs769450 may be associated with epileptic drug resistance in a central Chinese Han population.

Objective To assess the prevalence of metabolic syndrome (MS) and explore the associated risk factors with MS among 35 ～ 80 years elderly people in Changsha.Methods The survey used by cluster random sampling method (from October to December,2008 ) was carried out by the Physical Examination Center of the Second Xiangya Hospital,Changsha.All subjects aged from 35 to 80 years old had the questionnaires,physical examination,and biochemical measurements.MS was defined by IDF 2005.Results The prevalence of MS was 24.3％ among elderly people in Changsha.The prevalence of MS in male and female was 27.9％ and 19.3％,respectively; which in male was significantly higher than in females ( P ＜0.01).According to census of 2000 in Changsha,the age-adjusted rate of MS was 24.4％ among elderly people,27.8％ in male and 21.9％ in female,respectively.The metabolic abnormalities and the prevalence rate of MS were different in gender and age.Except the essential component of the central obesity in the 194 cases of MS patients,there are 80 cases include other two kinds of metabolic abnormalities,accounting for 41.2％,most of them with elevated blood pressure + sugar metabolism disorders; the most common three kinds of metabolic abnormalities of the 78 cases,accounting for 40.2％ of the people with MS,most of them with high TG + elevated blood pressure + sugar metabolism disorders; With 4 kinds of metabolic abnormalities of 36 patients,accounting for 18.6％ of the MS patients.Increasing age,male,overweight and (or) obesity,high LDL-C hematic disease,high uric acid hematic disease,diabetes were all the risk factors of the elderly people in Changsha city.Conclusions Elderly people in Changsha have a relatively high prevalence of MS,especially for male.The prevalence of MS is considerably high in Changsha,which may continue to rising with the social economic development and population aging.There is an urgent need to take actions to reduce the burden of MS.

Objective To evaluate the value of percutaneous transhepatic angioplasty in treatment of portal vein stenosis (PVS) after pediatric liver transplantation.Methods The data of 8 pediatric patients with PVS after liver transplantation were retrospectively evaluated.All cases were confirmed by portal vein angiography,and were treated with percutaneous transluminal angioplasty and/or percutaneous transluminal stent angioplasty.The effect of endovascular interventional therapy in 8 cases was analyzed.Results A total of 12 times of 8 patients received endovascular interventional therapy.The success rate was 66.67％ (8/12).The clinical success rate of the first treatment was 62.50％ (5/8).Three cases were treated with balloon dilation after the first balloon dilation,and there was no recurrence of PVS after operation in 2 cases.After the treatment of balloon dilation,stent angioplasty was performed in 1 case.There were no complications related to treatment in 8 cases.Conclusion Endovascular interventional treatment is a safe and effective way for PVS after pediatric liver transplantation.
