The purpose of this study was to investigate the function of stereo visual acuity in patients after phacoemulsifications and intraocular lens implantation. Mensuration of stereopsis with laser holographic stereovision test chart was done in 80 cases who had undergone phacoemulsifications and intraocular lens implantation. In this group, 43 patients were male, 37 were female .Ages of the patients were 52 to 81 years. Single eye operation was done in 18 cases, while both eye operation in 62 cases. The corrected vision was all over 0 4 in both eyes.In the 80 cases 67 (83 7%) had near stereopsis and 13 cases (16 3%)did not have; 71 cases (88 8%) had distance stereopsis and 9 cases (11 2%)did not have. Function of stereopsis weakens gradually following aging and is closely related with vision. The function of sterovision would recover to varying degrees after phacoemulsifications and intraocular lens implantation. Recovery of distance stereopsis was better than that of near stereopsis.The results of this study show that the status of stereopsis is an important index to evaluate the curative effect in patients after phacoemulsifications and intraocular lens implantation.

AIM To investigate the therapeutic effect of boanmycin (BAM, bleomycin A6) on colon carcinoma 26 and its hepatic metastasis in mice. METHODS A series of models including subcutaneous transplantation, orthotopic transplantation in cecum subserosa, intra-hepatic transplantation of tumor, and intra-splenic transplantation of tumor accompanied with hepatic metastases were employed. In addition, LEICA Q 500IW image analysis system was used to determine the area of metastatic lesions in the liver in histopathological sections. RESULTS BAM at 5 mg*kg-1 and 2.5 mg*kg-1 inhibited the growth of subcutaneous tumors by 78.7% and 61.9%, and the orthotopic tumors by 99.4% and 90.0%; and the intra-hepatic tumors by 86.9% and 75.7%, respectively. Determined by the numbers of metastatic nodules, BAM at 10 mg*kg-1 and 5 mg*kg-1 inhibited hepatic metastases from intra-splenic transplantation by 97.6% and 56.8%; and evaluated by image analysis of metastatic lesions, by 100% and 63.3%, respectively. CONCLUSION Boanmycin is highly effective in a panel of models including the subcutaneous, orthotopic, intra-hepatic transplanted tumors, and hepatic metastases of murine colon carcinoma 26.

Objectives:To establish animal model of anterior proliferative vitreoretinopathy (aPVR) with cultured homologous dermal fibroblasts of rabbit, and to provide evidence why hypotony was caused by aPVR. Methods:Animal models of aPVR were established with cultured homologous dermal fibroblasts on pigmented rabbits. Rabbits were sacrificed on the 14th, 28th and 56th day after the operation to prepare naked eyes and to receive histological examinations. Results:Naked eye examination showed that the peripheral retina was detached by dragging in the experimental group 28 and 56 days postoperatively. Microscopic examination showed atrophy or absence of the non-pigmented ciliary epithelium on the 28th and 56th postoperative day in the experimental group. Conclusions:The epiciliary membrane in aPVR dragged the ciliary body, made atrophy of non-pigmented epithelium, which perhaps was the main cause of hypotony.

Objective To evaluate the value of admission test of fetal heart rate and artificial rup-ture of membrane in predicting fetal distress in labor. Methods 658 pregnant women who had been pregnant for 33+5 to 43 weeks and delivered spontaneously in 24 hours were divided into low risk group(598 cases) and hign risk group(60 cases) according to their admission test. The admission test, result of deliv-ery, amniotic fluid contamination and Apgar scores of newborns were analyzed. Results 515 cases were reactive type(78.27%), 72 cases were equivocal type(10.94%) and 71 cases were ominous type(10.79%). Total incidence of neonatal asphyxia were 6.53%,and it was 1.94% and 33.08% in reactive type subjects and ominous type subjects, respectively. The rates of anmiotic fluid contamination were 20. 97% and 67.61% in reactive type subjects and ominous type subjects (P<0.01). The incidence of reactive type and equivocal type of amniotic fluid contamination and neonatal asphyxia were significantly lower in the low risk group than those in the high-risk group (P<0.05). Conclusions Reactive type of admission test can ensure safety of fetus during the subsequent four to five hours. Admission test of fetal heart rate and artifi-cial rupture of membrane can be used to predict fetal outcome in labor.

Objective To investigate the expression and clinical significance of mammalian sterile 20-like kinase 1 (MST1) in cervical cancer. Methods Immunohistochemical method was applied to detect the expression level of MST1 protein in specimens of cervical cancer tissues (n=139) and pericarcinomatous tissues (n=20, with≥4 cm distance from the primary tumor's edge). Western blot assay and qPCR were used to detect the protein and mRNA transcription expression levels of MST1 in 20 pairs of cervical cancer tissues and pericarcinomatous tissues, respectively. The correlation between MST1 expression, clinic pathological features and the prognosis were analyzed. Results MST1 was mainly expressed in cytoplasm. The positive expression rate of MST1 was significantly lower in cervical cancer tissues (27%, 38/139) than that in pericarcinomatous tissues (80%, 16/20,χ2=21.62, P<0.01). The expressions levels of MST1 protein and mRNA were both lower in the cervical cancer tissues (P<0.01). In cervical cancer, the positive expression rate of MST1 inⅠb+Ⅱa stage was higher than that ofⅡb+Ⅳstage (P<0.05), the positive expression rate of MST1 in lymph node metastasis was lower than that of without lymph node metastasis (P < 0.05). Values of age, tumor size, histological type and differentiation degree showed no significant difference to positive expression rate of MST1. Moreover, the negative expression of MST1 displayed a significantly poorer overall survival time than that of positive expression of MST1 (Log-rank χ2=28.35, P < 0.01). Conclusion MST1 shows a lower expression in cervical cancer, which may be a new target for clinical treatment and prognosis of cervical cancer.
