Objective To evaluate the activities of daily living (ADL) and investigate its influential factor in primary angle-closure glaucoma patients.Methods One hundred primary angle-closure glaucoma patients (acute phase) diagnosed definitely from April to October 2014 were collected.The status of sex,gender,education,income were recorded.Barthel Index (BI),Hospital Anxiety and Depression Scale (HADS) and Glaucoma Quality of Life-15 (GQL-15) were respectively used to assess the ADL,anxiety and depression symptoms and visual quality of life in primary angle-closure glaucoma patients.At the same time the factors affecting ADL of primary angle-closure glaucoma were analyzed.Results There were no dysfunction in 12 patients,46 patients with mild dysfunction,32 patients with moderate dysfunction and 10％ (10/100) patients with severe dysfunction.BI was negatively correlated with anxiety and depression score,GQL-15 results and disease course (r=-0.819-0.395,P ＜ 0.01),and positively correlated with average monthly income (r=0.453,P ＜ 0.01).There were no correlation with gender,sex and education (r=-0.159-0.172,P ＞ 0.05).Conclusions ADL of primary angle-closure glaucoma patients has varying degrees of dysfunction,and disease course,average monthly income,anxiety,depression and visual quality of life are closely related with it.

Objective To provide an effective imaging technique for the morphological observation of the urogenital hiatus in pelvic organ prolapse women using three-dimensional ultrasound. Methods In a prospective observational study, forty patients with pelvic organ prolapse and thirty nulliparous women underwent three-dimensional transperineal ultrasound, with the patients supine after bladder emptying. The three-dimensional ultrasound volume was acquired and the form, structure, composition and size of urogeital hiatus were observed in the axial plane set by interior-inferior edge of symphsis pubis and analrectum junction. Results The urogenital hiatus in pelvic organ prolapse women was obviously different from the control's. The size increased sharply, the morphology represented as oval replacing the normal rotundity, the middle line diverged from the normal position, organs inside the hiatus arranged abnormally and the connective tissue defected. Conclusions Three-dimensional ultrasound is an effective imaging method to observe female pelvic floor. Urogenital hiatus in pelvic organ prolapse women displayed abnormities with morphology and structure.

Objectives To investigate the role of lymphangiogenesis in the perineural micrometastasis of pancreatic adenocarcinoma. Methods The clinical data of 30 pancreatic adenocarcinoma patients who were admitted from Sep. 2005 to Oct. 2006 for extended radical surgery were collected. The samples including pancreatic cancer, adjacent tissue, lower bile duct, pancreatic tail, the structure surrounding the SMA (peripancreatic nerve plexus) and lymph nodes were collected during operation. They were subjected to conventional pathological examination. The lymphatic capillaries weredetected by double immunohistochemical staining and the lymphatic vessel density ( LVD) was measured. Results Intra-pancreatic and/or peripancreatic neural invasion was observed in 25 patients (83. 3% ) , of which 20 were found to have both the peri-pancreatic and intra-pancreatic neural invasion. The other 5 only had the intrapancreatic neural fiber invasion and there was no single patient with peri-pancreatic neural fiber invasion only. Peri-neural invasion was not significantly associated with patients' age, gender, lymph node metastasis, tumor size and the location (P > 0.05) , but was obviously associated with JPS clinical staging ( P < 0. 05 ). The mean intratumoral LVD was (4.2 ±3.4) per field, which was significantly lower than (11.3 ±6.9) per field of adjacent tissue and (10.8 ±4.4)per field of normal pancreatic tissue(P<0.01). The mean intratumoral LVD between adjacent tissue and normal pancreatic tissue was not statistically different. Lymphatic vessel invasion was observed in non-malignant tissues in 18 patients, and there was a distribution correlation between lymphatic vessel invasion and extra-pancreatic neural plexus invasion (P<0.05). Conclusions The incidence of peri-neural invasion was high, peri-neural invasion was associated with JPS clinical staging and lymphatic vessel invasion, which suggested the possibility of the cancer spreading by peritumoral lymphangiogenesis route into the peri-SMA neural plexuses.

This study was designed to investigate the impact of ultra-filtration extract mixture from Astragals mongholicus (UEMAM) o radiosensitivity of H22 ascitic tumor in mice to 12C6+ ions radiation. The H22 ascitic tumor model was established in mice by intraperitoneal injection of 0.2 mL H22 ascitic cells. The animals were subsequently divided into 4 groups randomly, treated with normal saline, UEMAM, heavy ion beam radiotherapy and UEMAM plus heavy ion beam radiotherapy, respectively. The body weights, abdomen circumference of the mice were measured and the mouse behavior was monitored every day; survival time was recorded to evaluate life extension effect; flow cytometry technique was used to detect H22 cell apoptosis and cell cycle; protein levels of p53, Bax, Bcl-2 and cleaved Caspase-3 were analyzed by Western blot; the single cell gel electrophoresis was used to detect the level of deoxyribonucleic acid damage (DNA damage). The results suggest that UEMAM significantly increased survival time, and decreased body weights and abdomen circumference over the saline control group. The treatment increased cell apoptosis, cycle arrest and DNA damage compared to the saline control group. UEMAM significantly enhanced the therapeutic effect of heavy ion beam radiation in survival time, and decreased body weights and abdomen circumference in the tumor-baring mice. The combination increased cell apoptosis, cycle arrest and DNA damage compared to the radiotherapy group. The results of Western blot suggest that the treatment significantly enhanced p53-induced apoptotic signals. The experiment discovered that UEMAM could improve radiosensitivity of H22 ascitic tumor through activation of p53-mediated apoptotic signal pathway.

Objective:To study the amino acid and codon usage profile of HIV-1 Env gene in donors whose serum exhibit highly broad cross-neutralizing activity. Methods:The samples were divided into highly broad cross-neutralizing activity group (hBCN + group) and non-highly broad cross-neutralizing activity group (hBCN - group) based on whether the neutralization breadth was higher than 90% or not. Full-length Env genes were amplified by single genome amplification (SGA) method from patients′ plasma samples, and the characteristics of Env sequences in hBCN + group were compared with hBCN - group. The correspondence analysis (COA) on relative amino acid usage (RAAU), adaptability to host based on similarity index D( A, B) and relative synonymous codon usage (RSCU) values of Env genes (hBCN + and hBCN -) with respect to human host RSCU were analyzed. Results:Correspondence analysis showed that the RAAU data of hBCN + group and hBCN - group were distributed along the two main axes to form two relatively separated clusters, indicating that the Env genes of the two groups had relatively unique amino acid usage patterns; the similarity index calculation results showed that hBCN + group (0.097) was lower than the hBCN - group (0.102), in addition, the Env gene of the hBCN + group had less frequency of similarly selected codons with human host system compared to hBCN - group. Conclusions:Env genes in hBCN + group and hBCN - group may have relatively unique amino acid usage patterns, and virus strains in hBCN + group are less adaptable to the host than those in hBCN - group.

Objective: To prepare the sustained-release solid dispersion of tripterin (SRSDT) with the intention of improving drug dissolution, meanwhile, the drug release was slowed down so as to make the toxicity diminished. Methods: SRSDT was prepared by the solvent method with colloidal silica dioxide (CSD) as carrier. The physical characteristics and in vitro release rate were further evaluated. Results: The ideal SRSDT was prepared by mixing tripterin and colloidal silica dioxide with the weight ratio of 1:12; The release rate of drug could keep moderate and controllable. In vitro cumulative release of SRSDT was up to more than 90% after 8 h. The results of differential scanning calorimetry, scanning electron microscopy, and X-ray powder diffraction could prove that the tripterin existed as amorphous form in the carrier. Conclusion: The SRSDT carried by CSD could control the release rate of drug and keep moderate and controllable, and the preparation process is simple, which has potential applications.
