Objective To explore the effect of yam polysaccharide for the diabetic mice. Methods Ninty mice were randomly divided into three groups ,yam polysaccharide group(n = 30), glibenclamide group (n = 30) and control group(n = 30). Mice were Intraperitoneal injection of alloxan (200mg/kg) to establish diabetic model. Yam polysaccharide group was administered yam polysaccharide for 12d. Results Yam polysaccharide significantly decreased the blood sugar of the diabetic mice. There were not significantly different in two groups (P ＞ 0.05).Conclusion Yam polysaccharide had obvious role in decreasing blood glucose.

In order to explore the value of p63, smoothmuscle actin (alpha-SMA) and cytokeratin 5/6 (CK5/6) in the differential diagnosis of ductal lesions of breast, 88 tissue specimens of ductal lesions of breast were collected and examined histologically by HE staining. By using immunohistochemistry, the expression of p63, alpha-SMA and CK5/6 was detected. The results showed that in 38 cases of benign breast lesions, the proliferating cells were all positive for p63 and alpha-SMA. In 19 cases of ductal carcinoma in situ (DCIS) and 7 cases of intraductal papillary carcinoma, alpha-SMA positive cells formed a layer of continuous embroider-shaped structure and the p63 positive cells formed a layer of evenly separated embroider-shaped structure around the ducts. There was no cross-reaction between p63 and interstitial myofibroblasts and vascular smooth muscle cells. In 38 cases of benign breast lesions, the positive rate of CK5/6 expression was 100%. In 5 cases of atypical ductal hyperplasia, there were few positive cells in the ducts. In 19 cases of CDIS, no tumor cells expressed CK5/6. In 19 cases of invasive ductal carcinoma, almost no CK5/6 was detectable. It was suggested that p63 could serve as a novel specific marker for the identification of breast myoepithelial cells. CK5/6 is of value in differentiating ductal proliferation of varying degrees, especially in the differentiation between cancerous and non-cancerous changes. Simultaneous detection of p63, CK5/6 and alpha-SMA can help increase the diagnostic accuracy of breast diseases.

This paper presents the first description of the morphology of Demodex brevis examined by scanning electron microscopy.The authors found that D.brevis can be distinguished from D.folliculorum by the characteristic features of the following structures: the flat gnatho-soma,the humplike podosoma and the absence of transverse striation on its anterior dorsal Surface,the suprecoxal spines,the hypostome,the oral opening,the pedipalpal claws and the claws on legs,and the ennuli of the terminal part of the opisthosoma.The morphology of the above structures observed are briefly compared with those of D.folliculorum.

Objective To observe the baseline characteristics and visual outcomes after two years follow-up of exudative age-related macular degeneration (AMD) patients treated with ranibizumb. Methods Forty-four eyes of 44 patients with exudative AMD were enrolled into this retrospective study, 19 were men and 25 were women. The mean age was 78 years (range 64–92 years). All patients were underwent best corrected visual acuity (BCVA, Early Treatment of Diabetic Retinopathy Study), fundus color photography, fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA) and optical coherence tomography (OCT). The mean BCVA was (50.36±14.43) letters, the mean central foveal thickness (CFT) was (291.95± 82.19)μm, and the fluorescence leakage area of choroidal neovascularization (CNV) was (7.61±5.84) mm2. All patients received three initial intravitreous injection of ranibizumb (IVR) and were retreated with monthly IVR when needed. The mean follow up time was 25.6 months (range 24–29 months). On 1, 2, 3, 6, 12, 18 and 24 months after treatment, BCVA and OCT were repeated. On 3, 6, 12, 18 and 24 months after treatment, FFA and ICGA were repeated. The change of BCVA, CFT and fluorescence leakage area of CNV were observed. The association of baseline characteristics and two year visual outcomes were analyzed. Results On 1, 2, 3, 6, 12, 18 and 24 months after treatment, the BCVA were improved significantly (t=?1.89,?3.51,?4.61,?4.04,?5.77,?4.69;P<0.05), the CFT were decreased significantly (t=1.51, 2.30, 3.40, 3.28, 3.54, 3.88, 3.73;P<0.05). On 3, 6, 12, 18 and 24 months after treatment, the fluorescence leakage area of CNV were reduced significantly (t=2.12, 2.90, 3.51, 4.12, 4.06;P<0.05). The lower baseline BCVA, the more improved after treatment. The BCVA improvement degree has a negative relationship with baseline BCVA and fluorescence leakage area of CNV (r=0.505,?0.550;P<0.05), but no correlation with baseline CFT (r=0.210, P>0.05). Conclusion Two year visual outcomes of exudative AMD patients treated with ranibizumb is negative correlated with baseline BCVA and fluorescence leakage area of CNV, but not correlated with baseline CFT.

Objective To evaluate the efficacy of intravitreal injections of conbercept in choroidal neovascularization (CNV) secondary to pathologic myopia (PM).Methods A retrospective case series of 37 eyes of 37 patients affected with CNV secondary to PM treated by intravitreal injections of Conbercept.All the patients were examined with best-corrected visual acuity (BCVA) of Early Treatment Diabetic Retinopathy Study (ETDRS) chart,central macular thickness (CMT) of optical coherence tomography (OCT) at baseline.The initial average letters of ETDRS BCVA was 49.86±8.87,CMT was (306.38±31.01) μm.All eyes were treated with intravitreal Conbercept 0.05 ml (10 mg/ml).Follow up visits were performed monthly after injection.The mean follow-up time was 16.8 months.Injections were repeated according to the situation of BCVA,CMT,subretinal fluid and CNV leakage in follow-up.All eyes received an average of 4.8 injections.BCVA,CMT and ophthalmoscope examination were assessed monthly.The relationship of BCVA improvement and CMT reduction with the data at baseline and number of treatments were analyzed by Spearman Rho correlation respectively.Results During the 1,3,6 and 12 months after treatment,the mean BCVA were all improved with statistically significant difference (t=17.629,P＜0.01).At 12 months,15 eyes (45.9％) had improvement of 15 letters or more,32 eyes (86.5％) had improvement of 5 letters or more,and 1 eye (2.7％) had decreased more than 5 letters.During the 1,3,6 and 12 months after treatment,the mean CMT were all decreased with statistically significant difference (F=43.726,P＜0.01).At 12 months,the retinal fluid of 34 eyes (91.9％) were absorbed completely;33 eyes (89.2％) had angiographic closure at that time.There was no significant relevance between BCVA improvement and sex,age and course of the disease (P＞0.05),but a significant negative correlation was found between the BCVA improvement and BCVA at baseline,injection times (P＜0.05).There was no significant relevance between CMT reduction and sex,age,course of the disease and injection times (P＞0.05),but a significant positive correlation was found between CMT reduction and CMT at baseline (P＜0.05).There were no systemic or ocular serious side effects during the follow up.Conclusions Intravitreal injections of Conbercept showed BCVA improvement and CMT reduction.It appeared to be effective and safe for choroidal neovascularization secondary to pathologic myopia.Intravitreal Conbercept for CNV secondary to PM showed BCVA improvement,CMT reduction and safety.

To explore the correlation between the C807T polymorphism of platelet membrane glycoprotein I a (GP I a) gene and aspirin resistance in Chinese people, 200 patients with high-risk of atherosclerosis took aspirin (100 mg/d) for 7 days. Platelet aggregation function was detected using adenosine diphosphate (ADP) and arachidonic acid (AA) before and after the administration of aspirin. Then the subjects were divided into three groups according to the results of platelet aggregation function: an aspirin resistant (AR) group, an aspirin semi-responder (ASR) group and an aspirin-sensitive (AS) group. Platelet GP I a gene 807CT polymorphism was examined by means of polymerase chain reaction-sequence specific primers (PCR-SSP). The results showed that T allelic frequency in AR group and ASR group were higher that of AS group (P<0.005), and the prevalence of genotypes (TT+TC) of these two groups was significantly higher than that in AS group (P<0.05). Platelet GP I a T allele was significantly associated with aspirin resistance as revealed by multiple logistic regression (OR=3.76, 95% CI: 2.87-9.58). The results suggest that inherited platelet GP I a variations may have an important impact on aspirin resistance and the presence of GP I a T allele may be a marker of genetic susceptibility to aspirin resistance.
