The treatment of myopic amblyopia and myopic anisometropic amblyopia is difficult and usually resultless and it has been the obstacle of amblyopic treatment. Corneal contact lens, corneal refractive surgery and phakic intraocular lens as new methods can significantly improve visual acuity of patients with high myopic amblopia and myopic anisometorpic ambyopia. For correcting myopia and myopic anisometropic amblyopia it provides a new method. This paper discusses the availibility and safty of above methods for the treatment of myopic amblyopia and myopic anisometropic amblyopia.

Objective To investigate the morphological features,biological behavior ,and diagnosis and treatment of gastric hepatoid adenocarcinoma(GHA).MethodsTwenty GHA cases were evaluated. Of the 20 patients,14 underwent radical gastrectomy, 3 total gastrectomy,3 total gastrectomy and wedge excision of the liver metastasis.ResultsHistologically,hyaline globules and venous invasion were common features of GHA.Tumor cells were immunohistochemically positive for alpha fetoprotein(AFP), alpha antitrypsin(AAT), and alpha antichymotrypsin(ACT). Ultrastructurally,tumor cells were arranged toward the lumens with microvilli on the luminal surfaces.There were junctional complexes between the lateral plasma membranes of adjacent tumor cells.Patients were followed up for 1～5 years with 12 deaths, 11 died of metastasis and one died of intraabdominal tumor seeding. The 1, 3 year survival rate was 44%(8/18), and 17%(3/18), respectively. Conclusions GHA deriving from gastric mucosa is characterized both by the histologic structures of hepatoid differentiation and adenocarcinoma.The prognosis is usually poor due to frequent liver metastasis.

Objective To evaluate the application of mobile ultrasonoscope in earthquake rescue. Methods According to the characteristic of environment and traumatic conditions in earthquake area, the mobile ultrasonoscope was used to diagnose for clinicians, and the advantages and disadvantages were evaluated. Results The mobile ultrasonoscope played an important role in routine diagnosis, such as organic injury and calculus, superficial organellae injury, soft tissue injury, injury of limbs and blood vessels, gynaecology and obstetrics and so on. As far as certain conditions were conferred in which the mobile ultrasonoscope was seldom used to diagnose in common practice, it played a dramatic role too in bone fracture, joint damage, craniocerebral injury and foreign objects. Conclusion In routine diagnosis or certain conditions, the mobile ultrasonoscope is very practical, especially in earthquake rescue.

ObjectiveTo investigate the genomic and non-genomic effects of 17β-estradiol on gallbladder smooth muscle strips of guinea pig and their possible mechanism. MethodsAfter ovariectomized operation (OVX) and subcutaneous injection of 17β-estradiol, the contents of serum estradiol and cholecystokinin-octopeptide (CCK-8) of the sham operation group (Sham) guinea pigs, the OVX group, the OVX and subcutaneous injection 17β-estradiol for 1 day (OVX+E2, 1 d), 3 days (OVX+E2, 3 d) and 7 days (OVX+E2, 7 d) were detected by EILSA respectively. The effects of CCK-8/Ach on constriction of gallbladder muscle strip were observed among various groups by using tension transducer, and the acute effects of 17β-estradiol on guinea pig gallbladder smooth muscle strips were observed to probe its possible mechanism. ResultsCompared with the Sham group, the serum contents of estradiol and CCK-8 decreased in OVX group (P＜ 0. 05) whereas the sensitivity of OVX guinea pigs gallbladder muscle strips to CCK-8/Ach increased (P＜0.05). With the extension of the subcutaneous injection 17β-estradiol time (for 1, 3, 7 days), both the serum estradiol and CCK level increased (P＜ 0.05) while the guinea pig gallbladder strips sensitivity to CCK-8/Ach decreased (P＜0.05).17β-estradiol at concentration ranging from 10 9 to 10-7 mol/L have no effect on the guinea pig gallbladder strips contraction (P＞0.05), but at concentration of 10-6 and 10 5 mol/L, it can inhibit the gallbladder contraction (P＜0.05). The blocking agents, such as nimodipine, atropine, devazepide, ICI 182,780 and Y-27632, can block the inhibited effects of 17β-estradiol. ConclusionThe 17β-estradiol can affect the gallbladder motility, both by genomic and non-genomic pathway.

Objective: To explore the relevant factors of acquired swallowing disorders in adult patients after cardiac surgery. Methods: A Jiatian water swallowing screening test was conducted for adult patients after cardiac surgery in our hospital from 2015-03 to 2015-09. There were 32 patients with acquired swallowing disorder deifned as Case group and meanwhile 420 patients without swallowing disorder at the same word deifned as Control group. Non-conditional Logistic regression analysis was applied to study the relevant factors for acquired swallowing disorders. Results: The overall incidence of acquired swallowing disorders was 7.08%. Multi Logistic regression analysis presented that duration of endotracheal intubation (OR=1.060,P<0.001), pre-operative arrhythmia (OR=2.780,P=0.019), NYHA grade (OR=1.789, P=0.033) and Euroscore (OR=1.216,P=0.040) were the relevant factors for the occurrence of acquired swallowing disorders in adult patients after cardiac surgery. Conclusion: Medical professionals should pay special attention to patients with above mentioned risk features at post-operative drinking to reduce the complications of acquired swallowing disorders.

Objective To investigate the incidence and clinical presentation of breast milk transmitted cytomegalovirus (CMV) infection among preterm infants with birth weight≤1500 g.Methods Preterm infants enrolled in this study met the following inclusion criteria: birth weight≤1500 g, fed with CMV-positive breast milk and admitted into Neonatal Intensive Care Unit of Children's Hospital of Fudan University within 72 hours after birth from October 2015 to July 2016. And those with congenital digestive tract malformation or congenital CMV infection were excluded. Breast milk and infants' urine samples were regularly screened for CMV DNA by fluorescent quantitative polymerase chain reaction. Symptoms and laboratory findings in infants with CMV infection transmitted via breast milk were documented and analyzed. Differences in relevant parameters were analyzed usingChi-square test, Fisher's exact test,t test or Mann-WhitneyU test where appropriately.Results Sixty preterm infants breastfed with CMV DAN-positive milk were recruited. Among them, 19 (31.7%) developed breast milk-acquired CMV infection as their urine samples were positive for CMV DNA, while the others were negative for CMV DNA (infected group:n=19; non-infected group:n=41). The average CMV copies in breast milk, gestational age and birth weight of the infected group were all significantly higher than those of the non-infected group [3.76 (3.18-4.50) vs 3.47 (3.00-4.88) Log10 copies/ml,Z=-2.042;(30.4±2.1) vs (28.4±2.3) weeks,t=3.175; 1290 (750-1500) vs 1110 (575-1480) g,Z=-2.837; all P<0.05). Fewer infants in the infected group than in the non-infected group received blood transfusion [5/19 vs 56.1%(23/41),χ2=4.627,P<0.05]. Ages of the infants with CMV infection ranged from 26 to 164 days (median age of 92 days). Six out of the 19 infants had clinical symptoms concurrent with viral excretion in urine and the ages of these symptomatic infants of infection were earlier than those of the asymptomatic ones without significance [(72±34) vs (97±28) days,t=-1.710,P>0.05]. Four infants (21.1%, 4/19) had severe organ damage and/or positive IgM antibodies to CMV in serum, and were treated with antiviral therapy. Two had mild symptoms and were not given antiviral therapy. All of the six symptomatic infants were followed-up for one to six months, during which time the complete blood cell count and results of biochemical test and fundus examination were back to normal.Conclusions The incidence of breast milk-acquired CMV infection among preterm infants with birth weight≤ 1500 g was 31.7%, and no severe symptoms were reported in this study.

Objective To explore the clinical effects of variable angle locking plate ( VLP ) in the treatment of pediatric subtrochanteric femoral fractures. Methods Between January 2012 and November 2014, 9 pre-school children were treated at our department for subtrochanteric femoral fractures. They were 6 boys and 3 girls, with an average age of 4. 8 years ( from 4 to 6 years ) . By the Seinsheimer classification, 5 cases were of typeⅡB and 2 of typeⅡC and 2 of typeⅢA. The intervals between injury and surgery averaged 3 days ( from 2 to 5 days ) . All of them were treated with open reduction and VLP internal fixation. Results All the wounds healed well without any infection. All the stitches were removed within 12 days. They were followed up for 8 to 26 months ( average, 16 months ) . All the fractures united within 3 months after operation. Follow-ups revealed no plate or screw loosening, or refracture at the same site. According to the Beaty imaging criteria, the early outcomes were all satisfactory. At the final follow-ups, all the children gained normal gait after full-weight rehabilitation. The affected and normal hips are nearly identical in range of motion and muscle strength. All the children recovered their pre-injury status. By the Sanders scoring for function of the affected hip, 7 cases were rated as excellent and 2 as good. Conclusion VLP can be an effective option for treatment of subtrochanteric femoral fractures in preschool children patients.
