Laser peripheral iridotomy ( LPI) is one of the main therapy for glaucoma due to its reliable efficacy of widening peripheral angle and therefore decreasing intraocular pressure by partially relieving pupillary block. The parameters of the anterior chamber angle following the LPI are the main evaluation indexes. At present,the detecting and diagnosis technique for the anterior chamber angle is deeply advancing, including gonioscopy, ultrasound biomicroscopy, anterior segment optical coherence tomography and Pentacam. These methods offer some useful parameters and also present with some limits in the application respectively in the evaluation of anterior chamber and angle structure. This review focuses on the application of Methods mentioned above and morphologic changes of anterior chamber and angle structure following the LPI.

The source of seed cells has always been the major problem in cartilage tissue engineering.Bone marrow stromal cells (BMSCs) have gradually become an optimal source of seed cells for cartilage engineering due to their high proliferative potential,multi-lineage differentiation potential and easiness to be obtained with minute trauma.The great challenge is how to get abundant BMSCs with a high purity and how to induce them in vitro into chondrogenic phenotype.This review aims to discuss the various strategies that can induce BMSCs chondrogenic differentiation in vitro so as to offer beneficial reference for constructing cartilage with BMSCs as seed cells.

Articular cartilage defects are commonly found in clinics. It is always a great challenge for the repair of cartilage defects due to the limited self-regeneration after injury. Tissue engineering,a newly emerging biotechnique to regenerate cartilage with chondrogenic potential cells and biodegradable scaffolds in vivo and in vitro,provides a promising method to solve the challenge in cartilage defects repair. To regenerate cartilage with favourable structure and function,it is essential to gain a deep insight into the biochemical structure,biomechanical property and their relationship of articular cartilage. This article gives an introduction to the biochemical structure,biomechanical property and their relationship of both native and tissue-engineered cartilage.

Objective: To observe the effects of Jinqi Jiangtang Tablet, a compound Chinese herbal medicine, on serum matrix metalloproteinase-9 (MMP-9) level and MMP-9 expression in peripheral blood monocytes of rats with streptozocin-induced diabetes. Methods: Thirty Wistar rats were randomly divided into 3 groups: control group, untreated group and Jinqi Jiangtang Tablet group. Diabetes in rats was induced by a single intraperitoneal injection of streptozocin (70mg/kg body weight). After model building, rats in the Jinqi Jiangtang Tablet group were administered with Jinqi Jiangtang tablets at a dose of 0.8 g/(kg·d) for 6 weeks and rats in the control group and the untreated group were treated with normal saline. After treatment, level of fasting serum glucose was detected by hexokinas method; serum MMP-9 level was tested by enzyme-linked immunosorbent assay; MMP-9 expression in peripheral blood monocytes was measured by reverse transcription-polymerase chain reaction and Western blot method. Results: After treatment, fasting serum glucose level in the Jinqi Jiangtang Tablet group was less than that in the untreated group (P<0.05). After modeling, the serum MMP-9 level of rats in the untreated group was (9.11±3.55) μg/L and that in Jinqi Jiangtang Tablet group was (8.97±3.07) μg/L, which were higher than that in the control group ((4.39±1.44) μg/L) (P<0.01). After gavage, the level of serum MMP-9 was lower in Jinqi Jiangtang Tablet group than in the untreated group (P<0.05). The expression of MMP-9 in peripheral blood monocytes in the untreated group was higher than that in the control group (P<0.05). The MMP-9 expression in peripheral blood monocytes of rats with diabetes was down-regulated by Jinqi Jiangtang Tablet (P<0.05). Conclusion: Jinqi Jiangtang Tablet can decrease the level of serum MMP-9 and down-regulate the MMP-9 expression in peripheral blood monocytes at both mRNA and protein levels in rats with diabetes.

The inverted terminal repeat (ITR) is the only cis element of AAV genome essential for rAAV rescue, replication and packaging. It is prone to mutation or loss when it is latent in host cell or in plasmid. Plasmids with different ITR types were cloned to compare the influence of ITR types on the AAV packaging and infectivity. The vector plasmids were transformed the competent SURE cells to get different colonies. The ITR types of plasmids were screened by digestion with SmaⅠ. AAV vector plasmid pScGFPud has two ITRs at both ends of AAV genome and plasmid pScGFPu has only one ITR at upstream end of AAV genome. When the two plasmids were co-transfected 293 cells to prepare rAAVs, 1.08?1013 viral particles (AAV1-GFPud) were produced from 20-dishes of 293 cells cotransfected with plasmid pScGFPud, 4.28?1012 viral particles (AAV1-GFPu) were produced from 20-dishes of 293 cells cotransfected with plasmid pScGFPu. Virus AAV1-GFPud infected 293, HeLa and NCI H446 cells more efficiently than did virus AAV1-GFPu. This suggests that defect ITRs in AAV genome is deleterious to AAV packaging and AAV infectivity and vector with complete ITRs is favorable to the yield and activity of rAAV.

Objective To assess the characteristic of left ventricular(LV) twist changed from infancy to the elder,in order to determine the normal value of LV twist in different age group.Methods After acquired basal and apical LV short-axis images in 293 healthy volunteers (aged 15 days to 72 years) by 2-dimensional echocardiography, speckle tracking echocardiography was used to analysis LV twist motion offline.The peak apical rotation (PAr), peak basal rotation (PBr), peak LV twist (Ptw), peak LV twist normalized by LV length ( PtwN), peak untwisting velocity ( PutwV), isovolumic untwisting% ( Iutw% ) in different group were compared.Results Reliable LV twist measurements were obtained in 274 volunteers.Different LV twist values were noted according to age.Ptw increased gradually with advancing age, when normalized by LV length, PtwN showed higher values before 3 years old and 25 to 45 years old.PutwV increased with aging from infancy to 25 years old, and leveled off from 25 to 45 years old, then decreased with advancing age.Iutw% was lowest before 3 years old,and increased gradually from 25 to 45 years old,then decreased with aging.Conclusions speckle tracking echocardiography can be used to noninvasively and exactly assess LV twist with high feasibility.The effect of aging on LV twist may reflect the process of maturational and adaptive modulation of LV torsional biomechanics from infancy to the elder.

Objective To make etiological and epidemiological investigation on the infection of Angiostrongylus canto-nensis in 8 pupils in Changle City. Methods (1) CSF of patients was examined with the conventional method to detect pathogens and eosinophiles. (2) The fecal samples of wild rodents were collected from the spot and examined microscopically to discover the first stage larvae of A. cantonensis. (3) Snails (Pila gigas) were collected in the spot. The smashed head tissue was examined for the third stage larvae of A. cantonensis. (4) The patient's clinical symptoms and physical signs were recorded with an emphasis on central nervous system. Results (1) Two larvae of the third stage of A. cantonensis were found in CSF of one patient. Eosinophiles occupied 68% of the cell number in average (ranged from 47% to 83%) in CSF of the 8 patients. (2) The infection rate of the first stage larvae of A. cantonensis was 39.3% (44/112) in feces of the rodents. (3) The infection rate of the third stage larvae of A. cantonensis was 40. 0% (82/205) in the snails. (4) Major clinical manifestations in the 8 patients included: severe headache(8/8), dizziness(8/8), nausea(8/8), vomiting(8/8), lethargy(7/8), lower limb hypody-namia(7/8). Conclusion The confirmation of severe infection of A. cantonensis in 8 child patients demonstrated that a natural nidus of angiostrongyliasis is present in Chengle City.

Objective To evaluate the CT findings and classification of the Le Fort fracture. Methods Sixty-two cases with Le Fort fractures were studied with thin-slice high-resolution CT scanning and analyzed with three-dimensional(3D)imaging reconstruction.Results Of the 62 patients,10 had Le Fort type Ⅰ fracture,9 had Le Fort type Ⅱ fracture,8 had Le Fort type Ⅲ fracture,and 35 had various combinations of the three types of Le Fort fractures,including 18 Le Fort Ⅰ+Ⅱ fracture,7 Le Fort Ⅰ+ Ⅱ+Ⅲ fracture and 10 Le Fort Ⅱ+Ⅲ fracture.Fifty-five cases had associated multiple fractures in the maxillofacial region.On 2D CT images,Le Fort fracture manifested as multiple and complex fractures. Though 2D image was better than 3D image in accurately defining tiny fractures and fractures of deep structures,the diagnosis of Le Fort fracture could not be correctly made solely on 2D image.3D CT clearly and stereoscopically demonstrated the entire shape and orientation of Le Fort fracture,thus facilitating the correct classification of Le Fort fracture.Conclusion 3D CT image is important in providing information about the space relationship of Le Fort fracture,thus very valuable for the preoperative planning.
