The ischemic myocardium in cultured myocardial cell of newborn rat and treated with Sodium Selenite(Se) and Fructose-1, 6-diphosphate(FDP) were studied comparatively by means of morphometry and quantitative cytochemistry. The area of myocardial cell and mitochondrion and the content of succinic dehydrogenase (SDH) in myocardial cell were quantitated by texture analysis system (TAS). Lipid peroxidation(LPO) and the myocardial cell beat function were observed. The results showed that the changes of the mitochondrion area interrelated with its number remarkabiy. When the mitochondrion area enlarges more than two fold, the destruction of mitochondrion is remarkable. Both Se and FDP can protect the ischemic myocardial cell, but the effects Se on forestalling destruction of mitochondrion, maintaining vitality of SDH and reducing content of malondialodehyde (MDA) are more powerful than FDP, and the effects of FDP on reducing edema of myocardial cell and mitochondrion, improving myocardial cell beat function are better than Se.

Palmer-foot hyperhidrosis is one kind of focal hyperhidrosis, with symptoms of sweating hands or feet. Some people even have sweat dripping off their hands or feet. This article studied the views of TCM on palmer-foot hyperhidrosis, expounded the pathological and physiological relationship between palmer-foot hyperhidrosis and spleen and stomach, and proposed that clinical treatment should be based on the syndrome differentiation and treatment of spleen and stomach, which can achieve certain efficacy.

The cytotoxic effect and antitumor effect of paclitaxel liposome were studied by using MTT assay method in vitro and in vivo antitumor test. The inhibitory rate of paclitaxel liposome on human ovarian cancer cell COC1 was 78.48 %, 84.90 %, 93.53 % respectively at the concentrations of 22.5 μg/ml, 45 μg/ml, 90 μg/ml respectively. Under the doses of 5 mg/(kg*d) and 10 mg/(kg*d) for 8 days, the inhibitory rate of paclitaxel liposome against xenograft of solid Ehrlich tumor in mice was 32.47 % and 54.63 % respectively (P<0.01). The weight change rate of the mice was 22.11 % and 21.16 % respectively. It was suggested that paclitaxel liposome possessed in vitro and in vivo antitumor activities. The toxicity of liposomal paclitaxel was lower than that of free paclitaxel.

Objective To determine the clinical valuation of different ways of hysteroscopic surgery for endometrial polyps. Methods Clinical effects were analysed retrospectively on total 86 patients underwent different ways of hysteroscopic surgery according to women physiological stages, the desire of fertility and clinical symptoms, the mean followed-up duration was (18±6) months. Results Among 86 cases, after polyps resected. In 53 cases menstrual change, 48 cases were cured, 5 cases were invalid. In 20 cases dysmenorrhea, 16 cases were valid, 4 cases were invalid. In 22 cases secondary anemia, 18 cases were cured, 4 cases recovered. Conclusions Fertile stage: uterine curettage should be undergone for patients without menstrual change after polyps resected; among patients with menstrual change, whole layer of endometria were resected for the ones (more than 40 ages) without desire of fertility and superficial layer of endometria were resected for the others after polyps resected. Perimenopause: uterine curettage should be undergone for patients without menstrual change and whole layer of endometria were reacted for patients with menstrual change after polyps resected. Postmenopause: uterine curettage should be undergone for patients without vaginal bleeding and endometria ablation should be carried out for patients with vaginal bleeding.

Chondroblastoma of the patella, rare occurred in patellar,is a kind of an uncommon benign bone tumor. Compared with giant cell tumor, the morbidity of chondroblastoma is lower. Meanwhile, its clinical manifestations are various, and images are very complicated. Therefore, the understanding of this kind of tumors may be limited even to the orthopedist. The differences of patellar chondroblastoma between other tumor in X-ray, CT and MRI is a spot in recent years. Sometimes patellar chondroblastoma coexists with aneurysmal bone cyst, which is a challenge to obtain an accurate pathological and radiological diagnosis. For the treatment, curettage and bone grafting is one the most popular method, but whether to perform a biopsy before surgery still remain controversy. Some new technique still has an unknown prospect for the treatment such as radiofrequency ablation.

Objective To investigate the difference between contrast sensitivity,noise and crowding phenomenon in normal and ametropic amblyopia children. Design Prospective case series. Participants 50 normal children and 50 ametropic amblyopia children. Method Using the noise visual acuity test chart,crowded visual acuity chart and contrast sensitivity visual chart of the visual perception system developed by the National Medical Care Apparatus Engineering Research Center,normal and ametropic amblyopia children were examined in Beijing Tongren Hospital. Main Outcome Measures The number and the constituent ratio of normal and abnormal children in contrast sensitivity,noise and crowding phenomenon. Results The abnormal results of contrast sensitivity in ametropic amblyopia children and normal children were 60 eyes (60%) and 15 eyes (15%) respectively; the abnormal result of noise visual acuity were 62 eyes (62%) and 30 eyes (30%) respectively; the crowded visual acuity were 56 eyes (56%) and 0 eye respectively (all P=0.000). In mild,moderate and severe ametropic amblyopia children,the abnormal results of contrast sensitivity were 32 eyes (51.61%),20 eyes (66.67%) and 8 eyes (100%) respectively (P=0.005),the abnormal results of crowding phenomenon were 30 eyes (48.39%),18 eyes (60%) and 8 eyes (100%) respectively (P=0.010),the abnormal results of noise were 39 eyes (69.90%),18 eyes (60.00%) and 5 eyes (62.5%) respectively (P=0.868). In mild,moderate and severe refractive error children,the abnormal results of contract sensitivity were 33 eyes (70.21%),9 eyes (34.12%) and 17 eyes (62.96%) respectively (P=0.011),the abnormal results of noise were 30 eyes (63.83%),15 eyes (57.69%) and 17 eyes (62.96%) respectively (P=0.868),the abnormal results of crowding phenomenon were 30 eyes (63.83%),11 eyes (42.31%) and 17 eyes (62.96%) respectively (P=0.172). Conclusion Contrast sensitivity,noise and crowding phenomenon in visual perception tests can be used to estimate the impairment of visual perception in amblyopia children.
