Chinese Traditional and Herbal Drugs 2018;49(13):3102-3109
Objective: To discriminate traditional She medicine Gegongniugen (the root of Rubus chingii Hu) from its confusable species of genus Rubus based on ITS2 barcode, and to guarantee the medicine quality and clinical effect of Gegongniugen. Methods: A total of 140 samples of R. corchorifolius L. f., R. hirsutus Thunb., R. parvifolius L., R. coreanus Miq., R. buergeri Miq., R.tsangorum Hand. -Mazz., R. trianthus Focke, R. jiangxiensis Z. X. Yu, W. T. Ji et H. Zheng were collected from Zhejiang, Guangxi, Jiangxi, and Anhui provinces. Genomic DNA was extracted from the collected samples, followed by ITS2 sequences amplification through PCR, bi-directional sequencing, assembly and annotation based on HMMer method. At the same time, 37 other sequences of corresponding species were downloaded from GenBank. Sequence characteristics such as lengths, GC contents, and variable sites were analyzed by Gene Tool software while genetic distance calculation and build-up of neighbor-joining (NJ) phylogenetic tree were carried out through Clustal X and MEGA 7.0. Results: The lengths of ITS2 sequences of Gegongniugen and its nine confusable species of genus Rubus ranged from 211 to 213 bp with GC content of 52.1%-58.0%; These ITS2 sequences had 14 mutation sites and one insertion/deletion site; The average intra-specific K2P genetic distance of Gegongniugen was 0.007 2, which was significantly lower than the respective inter-specific K2P genetic distance between Gegongniugen and its confusable species of genus Rubus. The genetic distantes between Gegongniugen and R. corchorifolius or Gegongniugen and R. jiangxiensis were minimum, while that between Gegongniugen and R. hirsutus was maxmum. It was obvious in the N-J phylogenetic tree that the ITS2 sequences of Gegongniugen formed into one separate clade, which could be successfully distinguished other nine species. Conclusion: ITS2 sequence can be used as an effective DNA marker to discriminate the original plants of Gegongniugen and its confusable species of genus Rubus, which provided an important molecular evidence for the identification of traditional She medicines and contributed to the information supervision of traditional She medicine market.

AIM: To retrospectively evaluate the effect of lens extraction combined with vitrectomy to treat traumatic lens dislocation with secondary glaucoma.
METHODS: Thirty - one eyes ( 31 cases ) of lens dislocation caused by blunt trauma with secondary glaucoma were treated respectively with cataract extraction combined with anterior vitrectomy, trabeculectomy and intraocular lens implantation. The visual acuity and pressure were observed 1wk, 1 and 3mo after operative.
RESULTS: Thirty - one eyes were all complete the operation successfully, and 6 eyes were given combined trabeculectomy, 9 eyes were implanted anterior chamber intraocular lens implantation ( IOL ) and 15 eyes were given posterior chamber suture fixation. Sixteen eyes were implanted in one-stage operation, while 8 eyes were implanted in two-stage operation. All intraocular pressure ( IOP ) were controlled to the normal level after operation and 23 eyes had visual acuity of more than 0. 3. CONCLUSION: Lens extraction combined with vitrectomy is an effective method for treatment of lens dislocation with secondary glaucoma. In order to control the IOP and get well visual function, we should choose IOL implantation or trabeculectomy according to the patient's condition.

Background Angle Kappa is the angle between the pupillary axis and visual axis,and it is a major consideration in corneal refractive surgery and strabismic surgery.Researches showed that age and refractive status affect angle Kappa value,and additionally,the measuring results of angle Kappa are associated with instruments.Objective This study was to investigate and weight the influences of axial length,anterior chamber depth and corneal curvature to angle Kappa.Methods A cross-sectional study was designed.Fifty health volunteers were included from Dec 2009 to Aug 2010,with the age of 18-38 years and average diopter of-1.0 D and best corrected visual acuity of 1.0.The horizontal and vertical angle Kappa was binocular measured with a testing machine designed by laboratory of School of Optometry & Ophthalmology Wenzhou Medical University.IOLMaster was employed to measure the ocular axial length,anterior chamber depth and corneal curvature radius.A multiple linear regression model was established to analyze the influences of axial length,anterior chamber depth and corneal curvature radius to angle Kappa.Results An efficacious regression equation was established as Y =15.554-0.587X1+0.724X2+ 0.232X3 with the independent variables as axial length(X1),anterior chamber depth (X2),corneal curvature (X3) and dependent variable as horizontal angle Kappa (Y) (R =0.788,R2 =0.621,P =0.000).Horizontal angle Kappa showed a negative correlation with axial length (b1 =-0.587,β1 =-1.002,P =0.000) and a positive correlation with anterior chamber depth (b2 =0.724,β32 =0.296,P =0.030).No significant correlation was found between corneal curvature radius and horizontal angle Kappa (b3 =-0.232,β3 =-0.068,P=0.338).A new regression equation was Y =14.235-0.622X1 + 0.824X2 after removed the corneal curvature variable (R =0.786,R2=0.618,P =0.000),with a negative correlation between horizontal angle Kappa and axial length (b1 =-0.622,β1 =-1.062,P<0.05) or positive correlation between horizontal angle Kappa and the anterior chamber depth (b2 =0.824,β2 =0.337,P<0.05).In addition,a multiple linear regression equation among 3 independent variables and dependent variable of vertical angle Kappa was Y =0.492-0.020X1 +0.038X2 +0.089X3 (R =0.436,R2 =0.191,P =0.000).However,no significant correlations were seen between vertical angle Kappa and axial length,anterior chamber depth or corneal curvature radius (all at P > 0.05).Conclusions Ocular axial length and anterior chamber depth have an obvious influence to horizontal but not vertical angle Kappa.Axial length appears to have more influence to horizontal angle Kappa than anterior chamber depth.

ObjectiveTo explore the effect of osteoarthritis (OA) chondrocytes and normal chondrocytes on the chondrogenesis of bone marrow mesenchymal stem cells(BMSCs) in self designed co-culture system. MethodsRabbit BMSCs and chondrocytes were isolated and expanded in vitro. OA chondrocytes were harvested from the rabbit of established osteoarthritis model. We made a BMSCs-low melting agarose constructs, then put it onto the self-made 6 well plates lattice assembly for co-culture with chondrocytes. The groups were divided into Normal P0-BMSCs, Normal P3-BMSCs, OA PO-BMSCs, OA P3-BMSCs and BMSCs (control) group. At 3, 7, 14 day culture, cultured cells in all groups were collected for real-time PCR, glycosaminoglycan (GAG) content, cytoactive detection, and histological observation. ResultsType Ⅱ collagen gene expression was up-regulated in group Normal PO-BMSCs, which showed 5.1-, 7.2-, 11.2-fold increase over that of control group at 3, 7, 14 days, respectively. Type Ⅰ, Ⅱ collagen and aggrecan gene expressions were not obviously up-regulated. In group OA P3-BMSCs, type Ⅰ collagen gene expression level lower than the control group in 3, 7, 14 day. In normal PO-BMSCs, GAG content showed 2.59-fold increase over that of the control group. GAG content of group OA PO-BMSCs and control group showed no significant differences.Others groups showed significant differences in comparison with the control group(P<0.05). Alcian stain showed positive in all groups. The normal PO-BMSCs group showed the darkest blue-stained. Conclusion Rabbit normal PO chondrocytes and rabbit OA P0 chondrocytes significantly enhanced chondrogenic differentiation of rabbit BMSCs. The secreted morphogens of the rabbit normal P3 chondrocytes and rabbit OA P3 chondrocytes do not have a significant effect on chondrogenic differentiation of rabbit BMSCs.
