AlM:To investigate the visual function in myopia and hyperopia amblyopia whose corrected visual acuity have recovered to normal.METHODS: The visual function of children ( 50 cases ) with amblyopia eyes by binocular vision correction after treatment above 0. 9 was checked. The simultaneous perception, fusion range and distance stereopsis were measured. According to the refractive condition of the children who were divided into group A ( myopia, 20 cases ) and group B ( hyperopia, 30 cases ) . The statistically difference of simultaneous perception, fusion function and stereopsis in two groups was analyzed. RESULTS: Fifteen ( 75%) and twenty - six ( 87%) children got the simultaneous perception in group A and group B respectively, and the differences between two groups were not significant (χ2=0. 454,P>0. 05). Group A had six children ( 30%) and group B had only seven children (23%) with the normal aggregative fusion range, two groups did not show any difference (χ2 =0. 565, P>0. 05). Respectively sixteen (80%),and twenty children ( 67%) had the normal divided fusion range in group A and group B, the recovery rate did not show any significant difference (χ2=0. 740, P>0. 05). Fifteen (50%) and seven ( 35%) patients acquired the far stereoscopic vision in group B and group A respectively, the recovery rate also did not show any significant difference. Normal distance stereopsis of 50 cases had 22 cases ( 44%) , and normal near stereopsis of 50 cases had 13cases ( 26%) Seven (23%) and 6 (30%) children got the normal near stereoscopic vision in group B and group A respectively, and the recovery rate did not show any significant difference (χ2=0. 195, P>0. 05;χ2=0. 295, P>0. 05).CONCLUSlON:After amblyopia treatment, although the children got the normal visual acuity, the binocular vision still can not completely normal in the short term. Myopia and hyperopia factor will not produce significant effect on binocular vision development.

OBJECTIVETo investigate the incidence of depression and its etiological factors in patients with cryptorchidism 6-16 years after surgical treatment.

METHODSUsing Self-Rating Depression Scale and Correlation Factor Questionnaire, we investigated the incidence of depression symptoms among 70 patients with cryptorchidism 6-16 years after surgical treatment and another 70 healthy males as controls, and analyzed the related factors of depression symptoms.

RESULTSThe incidence rate of depression symptoms was 50% in the cryptorchidism patients postoperatively, extremely significantly higher than 4.3% in the control group (χ2 = 23.5, P <0.01). Multiple stepwise regression analysis showed that the main risk factors of depression symptoms were worries about natural fertility (F = 15.8992, P <0.01), dissatisfaction with scrotal appearance (F = 4.6003, P <0.05), and the status of being married (F = 4.1002, P <0.05).

CONCLUSIONSymptoms of depression often occur in cryptorchidism patients after operation, and the major etiological factors are infertility, dissatisfaction with scrotal appearance, and the status of being married.

Objective To discuss the clinical application value of ultrasound contrast on evaluating fallopian tube patency.Methods Ultrasound contrast examination was conducted on 84 patients suffering from infertility and the flowing status of contrast agent in the uterine cavity and the fallopian tube and the distribution condition in the pelvic cavity were observed under the real -time ultrasound to judge the patency condition of the fallopian tube.Results After 84 patients receiving ultrasound contrast,38 cases'bilateral fallopian tubes were unobstructed,26 cases'lateral fallopian tube were unobstructed and 20 cases'bilateral fallopian were obstructed.Comparing the result of ultrasound contrast with laparoscopy,the diagnosis accuracy was 89.5%,the specificity 86% and the sensitivity 94%.Conclusion Fallopian tube ultrasound contrast technique can make an accurate and objective evaluation on the fallopian tube patency,it is an effective method to check fallopian tube patency and it is of high clinical application value.

BACKGROUND:Lithium chloridecan promote the proliferation and osteogenic capacity of bone marrow mesenchymal stem cels in the necrotic region after avascular necrosis of the femoral head, which has become an issue of concern. OBJECTIVE:To compare the advantages and disadvantages of bone marrow stem cel transplantation combined with lithium chloride in the treatment of rabbit femoral head necrosis. METHODS: Passage 2 bone marrow mesenchymal stem cels from 1-week-old New Zealand rabbits were cultured in 0, 5, 10, 20, 40 mmol/L lithium chloride. Forty-eight healthy adult New Zealand rabbits were selected to make femoral head necrosis models in the right femoral head using liquid nitrogen freezing method and then randomized into four groups: model group with no implantation; lithium chloride group given lithium chloride treatment at 3 days after modeling; cel transplantation group given gelatin sponge implantation and bone marrow mesenchymal stem cel suspension injection into the femoral head after modeling; combined group given bone marrow mesenchymal stem cel suspension injection and lithium chloride treatment. Intraperitoneal injection of lithium chloride (45.2 mg/kg) was given daily beginning at the postoperative 3rdday, and the treatment duration was 4 weeks. RESULTS AND CONCLUSION:Lithium chloride at 10 mmol/L had the maximum effect on the proliferation of rabbit bone marrow mesenchymal stem cels, and if the concentration of lithium chloride was > 10 mmol/L, the promotion role of lithium chloride began to decline. After combined treatment, the morphology of the femoral head was restored a little, with increased bone density and thickened trabecular bone; the level of β-catenin in the femoral head was significantly increased in the combined group compared with the cel transplantation group or the lithium chloride group. These findings show that bone marrow stem cel transplantation combined with lithium chloride treatment can promote the recovery from femoral head necrosis by increasing bone mass of the trabecular bone and bone density of the femoral head in the necrotic region.

To explore the binocular disparity information for children with a normal vision based on computer-assisted evaluation system.We examined the random dot zero-order disparity,line zero-order disparity,2nd-order disparity and random dot motion parallax for 97 children with normal vision.And 94 children reached 100″ vision disparity both in random dot zero-order disparity and line zero-order disparity (pass rate of 96.9％) ; all 94 cases passed the 2nd-order disparity and random dot motion parallax.Thus children with a normal vision develop their stereopsis.

Background:The incidence of ulcerative colitis (UC)in developed countries is higher than that in developing countries,which may be related with westernized lifestyle,especially high animal protein and low complex carbohydrate diet. With the increased high fat and meat intake,synthesis and secretion of bile acid in liver is also increased,which may have an impact on the occurrence of UC. Aims:To investigate the expressions of farnesoid X receptor (FXR)and G protein-coupled bile acid receptor 5 (TGR5)in patients with UC. Methods:Thirty patients with active UC from January 2013 to June 2016 at the Affiliated Jiangning Hospital of Nanjing Medical University were enrolled,and 30 healthy subjects were served as controls. Expressions of FXR and TGR5 were determined by immunohistochemistry. Results:Compared with control group,expression of FXR was significantly decreased in UC patients (4. 63 ± 2. 07 vs. 6. 91 ± 2. 62,P =0. 00),however,no significant difference in expression of TGR5 was found between the two groups (6. 70 ± 2. 90 vs. 6. 11 ± 2. 44,P = 0. 40). Expression of FXR was significantly increased in right hemicolon colitis than in left hemicolon colitis (P < 0. 05). Conclusions:There is a significant decrease in FXR in active UC patients,indicating that FXR may have some role in the pathogenesis of UC,however,TGR5 may have no obvious effect in the pathogenesis of UC.
