Abstract?AlM: To observe the effects of Shuangdanmingmu capsule on VEGF expression and retinal vascular morphology in rats with diabetic retinopathy ( DR) .?METHODS: DR rats were fed with Shuangdanmingmu capsule. By comparing with the normal group, the model control group, and positive control group, the effect of Shuangdanmingmu capsule on retinal tissue of DR rats was observed under electron microscopy. After HE staining, retinal structure was observed under the light microscope. lmmunohitochemical staining was used to detect the VEGF expression in retina.?RESULTS:Two months after treatment, the layers tissue of retina presented mild edema, capillary pericytes performed edema, mitochondria showed mild swelling and less clear structure, some endothelial cells showed slight proliferation in Shuangdanmingmu group. Compared with the normal group, the expression level of VEGF in retina increased in the other groups, especially in model control group. A significant differential in expression of VEGF was found between Shuangdanmingmu group, positive control group and model control group (P<0. 01).? CONCLUSlON: Shuangdanmingmu capsule can effectively improve the retinal microvascular, reduce edema and necrosis of each layer of retina, improve the ultrastructure of retina's tissue and inhibit VEGF expression in DR rats.

OBJECTIVE: To investigate the biomechanical characteristics of retinaculum in the treatment of femoral neck fractures. METHODS: The CT data of a 75-year-old female volunteer was processed by software to construct an intact femur model and femoral neck fracture model fixed with three cannulated screws, which were divided into models with retinaculum or not. The Von-Mises stress distribution and displacement were compared to analyze the stability differences between the different models to study the mechanical characteristics of the retinaculum in the treatment of femoral neck fractures. RESULTS: In the intact femur, the most obvious displacement appeared in the weight-bearing area of the femoral head, with retinaculum 0.381 37 mm, and without retinaculum 0.381 68 mm. The most concentrated part of the Von-Mises stress distribution was located in the medial and inferior part of the femoral neck, with retinaculum 11.80 MPa, without retinaculum 11.91 MPa. In the femoral neck fracture fixed with three cannulated screws model, the most obvious position of displacement also appeared in the weight-bearing area of the femoral head, with retinaculum 0.457 27 mm, without retinaculum 0.458 63 mm. The most concentrated part of the Von-Mises located at the medical and inferior part of the femoral neck, with retinaculum 59.22 MPa, without retinaculum 59.14 MPa. For the cannulated screws, the Von-Mises force peaks all appeared in the posterior and superior screw, with retinaculum 107.48 MPa, without retinaculum 110.84 MPa. Among the three screws, the Von-Mises stress of the anterior-superior screw was the smallest, which was 67.88 MPa vs 68.76 MPa in the retinaculum and non-retinaculum groups, respectively. CONCLUSION The complete retinaculum has little effect on the stability of intact femur and femoral neck fractures with anatomical reduction after internal fixation, and cannot effectively improve the stability of the fracture end after the fracture.

OBJECTIVE: To explore the relationship between best corrected visual acuity (BCVA) and refraction parameters in myopia. METHODS: Two thousand two hundred and seventy-four patients (4245 eyes) with different degrees of myopia were collected. Their BCVA, diopter of spherical (DS), diopter of cylinder (DC), astigmatism axis, axial length (AL) and corneal thickness were detected. The influence of those parameters on BCVA was studied and the mathematical model of the relationship between BCVA and other parameters including the age and gender of patients was established. RESULTS: The logistic regression analysis showed that there were correlations between the BCVA (y) and DS (x1), DC (x2), gender (x3), AL (x4), corneal thickness (x5), astigmatism axis (x6) and age (x7) (P<0.05): y=0.580 6-0.034 0 x1-0.046 8 x2+0.056 5 x3+0.016 5 x4+ 0.0007 x5+0.000 2 x6-0.005 8 x7. CONCLUSION For people with myopia, age, gender and corneal thickness have small effect on BCVA, while the DS, DC, AL and astigmatism axis have significant effect on BCVA. The BCVA would decline following the extension of DS, DC and AL. It is helpful to assess the vision of myopia by analyzing the refraction parameters comprehensively.

OBJECTIVETo study the mechanism of microelement including Cu and Zn on the accumulation of three danshinones in Salviae miltiorrhizae root and build a theory basis for its good quality and high yield.

METHODSand culture experiments were conducted to study the effect of Cu and Zn on the accumulation of three danshinones and oxidase including peroxidase and polyphenol oxidase activity in the plant root. The correlation between available Cu and Zn contents in matrix and oxidase activity in the plant root and, the correlation between available Cu and Zn contents in matrix and contents of tanshinones in the root were discussed.

RESULTContents of danshinones in the root increased with the increasing of Cu and Zn concentration. Dynamic monitoring on contents of dan-shinones of the plant roots growing in the pots with different Cu and Zn concentration in the whole growing season showed that the contents of danshinones for 60 days were the lowest, for 120 days the highest and then dropped for 150 days. In addition, among available Cu and Zn contents of matrix, oxidase including peroxidase and polyphenol oxidase activity and contents of tanshinones in the root,the correlation between two factors were significant difference (P < 0.05 or P < 0.01).

CONCLUSIONThe mechanism of Cu and Zn on the accumulation of danshinones may be that Cu and Zn improve the activity of peroxidase and polyphenol oxidase, which promote transformation of phenolic compounds to terpenes and therefore to increase contents of danshinones.

OBJECTIVETo explore the mechanism of laparoscopic adjustable gastric banding (LAGB) in the treatment of obese patients with type 2 diabetes mellitus (T2DM).

METHODSA total of 20 patients with obesity and T2DM were treated with LAGB. During the postoperative 1, 3, 6, 9, 12 months, the body weight changes were monitored and body mass indices (BMI) were calculated. The serum levels of leptin, GLP-1, and ghrelin were examined preoperatively and 1, 3, 6, 9, 12 months after LAGB using enzyme-linked-immunosorbent assay (ELISA). At the same time, the fasting serum insulin (FINS), C-peptide, glycated hemoglobin (HbA1c) levels were examined by electrochemiluminescence and the level of fasting blood glucose (FBG) was tested with oxidase test.

RESULTSAt postoperatively 12 months, all the 20 patients lost weight. The mean body weight decreased from (108 + or - 18) kg to (71 + or - 16) kg (P<0.05) and BMI decreased from 38 + or - 5 to 29 + or - 6 (P<0.05). The HOMA-IR decreased from (12.8 + or - 7.4) to (3.4 + or - 2.0) (P<0.01). The serum ghrelin level increased from (7.8 + or - 1.9) microg/L to (11.6 + or - 2.6) microg/L (P<0.01). The serum leptin level declined from (24.9 + or - 13.7) microg/L to(12.9 + or - 5.1) microg/L (P<0.01). The serum GLP-1 level increased from (0.58 + or - 0.12) microg/L to(0.80 + or - 0.06) microg/L (P<0.01). After LAGB, there were positive correlations between serum leptin level and FBG, FINS, HbA1c,and C-peptide level. Serum ghrelin and GLP-1 were negatively correlated with FBG, FINS, HbA1c,C-peptide.

CONCLUSIONSLAGB is effective in treatment of obesity patients with T2DM. The mechanism may be associated with the increase of serum GLP-1 and ghrelin and the decrease of serum leptin and insulin resistance.

BACKGROUNDThe elevated matrix metalloproteinase (MMP) activity is an important cause of chronic wound healing failure. Arsenolite, whose main component is arsenic trioxide (As2O3), is a common traditional Chinese medicine wildly used in treating chronic wounds; it can remove necrotic tissue and promote tissue regeneration. This research was designed to evaluate the effects of As2O3 on production and activities of MMP-1, MMP-2 and MMP-9, and on regulation of its signal transduction pathway in human skin fibroblasts (HSFb) and human monocyte line (THP-1 cells) that were in an inflammatory state.

METHODSWe established three cell models; HSFb activated by TNF-α, THP-1 cells activated by phorbol 12-myristate 13-acetate (PMA) and an HSFb-THP-1 co-culture system. Three cell models was cultured with As2O3 for 24 hours. The levels of MMP-1, MMP-2, MMP-9, TNF-α and IL-1β in the cell culture supernatants were assayed by ELISA. The mRNA expressions of MMP-1, MMP-2 and MMP-9 were determined by RT-PCR. The activities of MMP-2 and MMP-9 were tested by Gelatin zymography assays. The phosphorylation levels of ERK1/2 and p38MAPK were assayed by Western blotting.

RESULTSAs2O3 inhibited the expression of MMP-1, MMP-2 and MMP-9 mRNA, the secretion and activity of MMP-1, MMP-2 and MMP-9 in HSFb and THP-1 cells in the inflammatory state (P < 0.05 and P < 0.01 respectively). It also inhibited the secretion of TNF-α and IL-1β in THP-1 cells and in the co-culture system (P < 0.05 and P < 0.01, respectively). It also decreased the phosphorylation of ERK1/2 and p38 MAPK in HSFb and THP-1 cells (P < 0.05 and P < 0.01, respectively).

CONCLUSIONSAs2O3, as a main component of arsenolite, can inhibit the production of MMPs by HSFb and THP-1 cells in an inflammatory state through inhibiting the release of inflammatory factors and the activation of the MAPK cascade pathway. This may be a possible mechanism for arsenolite healing chronic wounds.
