Background Establising the culture model of Müller cells for obtaining the highly putified target cells is essential for the study about the physiology and pathology of retinal Müller cells. The exsiting purifing method for culturing Müller cells is dissatisfactory. Objective This study was to establish a method to obtain high purifing Müller cells. Methods The retina from 5 clean newborn SD rats were isolated and digested by 0. 01% trypsin and cultured in DMEM containing 10% fetal bovine serum. The cellular suspension was then prepared,and the target cells were screened using flow cytometry based on the size and the quantity of cells. Cultured and passaged cells were identified by transmission electron microscope and light microscope. Immunocytochemistry was used to detecte the expression of GFAP in cultured cells for the determination of type and purity of the cells. Results The cells showed the similar shape to retinal Müller cells after primarily culture with the large volume, and some small other types of cells could been seen. The growth of cells was quickly 3 weeks later. The fibroblasts were removed using sticking-wall by steps,and neurons were eliminated following passage. Aboundent of cellular organs were seen under the transmission electron microscope. The positive response rate of the cells for CFAP was 100%. Conclution Flow cytometry offer a rapid and feasible approach for purifying Muller cell and it builds the foundation for further study about Müller cells.

Objective To investigate the significance of helper T cell 1(Th1)/Th2 cytokines unbalance in children with hepatitis B virus-associated glomerulonephritis(HBV-GN).Methods The serum levels of interferon-gamma(IFN-?),interleukin-2(IL-2) and IL-4 were determined in 22 children with HBV-GN and 18 children with HBV by enzyme-linked immunosorbent assay(ELISA),respectively,and the difference of Th1/Th2 cytokines in the 2 groups.Results Serum levels of IL-2 and IFN-? in children with HBV-GN were decreased(P

0.05),but urine levels of MIF in children HSPN increased significantly than those in normal controls(P

Objective: To observe the clinical efficacy of heat-sensitive moxibustion for vascular dementia and explore its mechanism. Methods: A total of 70 patients with vascular dementia were randomized into an observation group and a control group, with 35 cases in each group. The control group was treated with piracetam, and the observation group was treated with heat-sensitive moxibustion on the basis of the treatment of the control group. The treatment lasted for 8 weeks. Before and after the treatment, the mini-mental state examination (MMSE), activity of daily living (ADL) and traditional Chinese medicine (TCM) symptom scores were assessed, and the levels of acetyl choline (Ach) and homocysteine (Hcy) were measured. The efficacy was evaluated after treatment. Results: The total effective rate of the observation group was significantly higher than that of the control group (P<0.05). After treatment, the MMSE and ADL scores in the observation group decreased significantly, and were lower than those in the control group (all P<0.05); the TCM symptom score of the observation group decreased significantly (P<0.05), while that of the control group had no significant change (P>0.05); the plasma Ach level in the observation group increased significantly (P<0.05), and the Hcy level decreased significantly (P<0.05), which were statistically different from those in the control group (both P<0.05). Conclusion: Heat-sensitive moxibustion plus piracetam is effective in treating vascular dementia. It can significantly improve dementia symptoms and ADL, which may be related to the correction of plasma Ach and Hcy levels.

Traditional Chinese medicine is a treasure of Chinese culture, absorbing the wisdom of the Chinese people. Continuous application of new technologies makes traditional Chinese medicine research advance with the times. After several years of development, high-throughput transcriptome study has become a mature research tool in biology. This paper reviewed the advances in medicine transcriptome study, and compared two sequencing platforms, Roche's GS FLX platform and Illumina's HiSeq 2000 platform. Moreover, this paper introduced medicine transcriptome analysis process, with Panax quinquefolius and Lonicera japonica for examples, showing the characteristics of traditional Chinese medicine transcriptome studies. High-throughput transcriptome studies facilitate traditional Chinese medicine research with overall understand of functional genes, give clear elucidation of metabolic pathways, lay molecular foundation for the traditional Chinese medicine research and offer modern interpretation for traditional Chinese medicine theory. However, the current study faces several difficulties, including weak molecular basis, high sequencing cost and staff shortages in data anaysis. In the future, with the development in sequencing technology, the combination of transcriptome and other genomics, such as proteome and metabolome, will lay a solid foundation for the new high-throughput screening and developing model for the traditional Chinese medicine industry.

OBJECTIVETo analyze micromovement of distal tihiofihular joints in different motion range of ankle joint ,and define the micromovement characteristic and range of distal tibiofihular joints.

METHODSTwelve normal Chinese were chosen. There were 9 males and 3 females, aged from 19 to 37 years old with an average (26.5 +/- 0.5) years. Detection terminals of laser photographic scanner were installed near the highest point between medial malleolus and lateral malleolos, the change of detection terminals on the position of dorsiflex, extension, introversion and eversion of ankle joint were scanned by 3D-laser scanner. The displacement of two detection terminals on the X ,Y and Z-axis (X-axis stands for the vertical-axis between coronal plane and Z-axis Y-axis stands for the vertical-axis between sagittal plane and Z-axis Z-axis stands for macroaxis of tibia).

RESULTSAlong with increased range of motion on the position of dorsiflex ,extension, introversion and eversion of ankle joint, the range of micromovement of distal tibiofibolar joints increased too. The max-displacement of X, Y and Z were respectively (1.04 +/- 0.12) mm, (1.70 +/- 0.16) mm and--(0.87 +/- 0.10) mm.

CONCLUSION3D-laser scanner can be used to determine the detailed displacement of distal tibiofibolar joint on the X , Y and Z, and measure the motion of distal tibiofibular joint. The method can be used to study the pathologic change of distal tibiofibular joint ,and provide basic biomechnics data for internal fixtor fitting for the characteristic of distal tibiofibular joint.

Objective:To evaluate the diagnostic value of digital breast tomosynthesis (DBT) and digital mammography (DM) for radial lesions.Methods:The data of 76 patients (78 lesions) with radial lesions confirmed by operation and pathology on DBT between December 2016 and May 2020 in the Affiliated Hospital of Qingdao University were analyzed retrospectively. Taking pathological results as the gold standard, 78 lesions were divided into benign radial lesions ( n=46) and malignant radial lesions ( n=32), and their DBT features were compared. According to the standard of breast imaging report and data system (BI-RADS), the wheel-spoke structure, central density, overall size, central size and surrounding burr length of the two groups of radial lesions were compared on DBT. Results:The detection rates of DM and DBT for 78 radial lesions were 59.0% (46/78) and 100% (78/78), the difference had statistically significant ( P<0.05). The diagnostic accuracy rates of DM and DBT for 78 radial lesions was 65.2% (30/46) and 74.4% (58/78), the difference had no statistically significant ( P>0.05). The sensitivity, specificity, misdiagnosis rates, missed diagnosis rates of DM and DBT in the diagnosis of malignant radial lesions were 64.3%(18/28) and 84.4%(27/32), 66.7% (12/18) and 67.4%(31/46), 33.3%(6/18) and 32.6%(15/46), 35.7%(10/28) and 15.6%(5/32), respectively. The difference was not statistically significant ( P>0.05). There were significant differences in the overall size of lesions [18.0 (14.9, 29.2) mm, 26.5 (20.2, 34.9) mm], central size [3.5 (2.5, 4.5) mm, 4.5 (3.5, 5.5) mm] and peripheral burr length [(11±6) mm, (13±4) mm] between benign and malignant radial lesions on DBT ( P<0.05). When the central size of the lesion was 5 mm, there was significant difference in the distribution of benign and malignant radial lesions ( P<0.05), and when the overall size of the lesion was 2 cm, there was significant difference in the distribution of benign and malignant radial lesions ( P<0.05). Conclusion:DBT can improve the detection and diagnosis accuracy of radial lesions, and provide an important basis for clinicians to make surgical treatment decisions.
