OBJECTIVETo observe the effect of Shenshuaining Granule (SG) combined telmisartan on serum creatinine (SCr) levels and urinary albumin contents in diabetic nephropathy (DN) patients, and to explore its efficacy.

METHODSTotally 204 DN patients were recruited, and further assigned to 3 groups, i.e., the early DN group, the clinical stage of DN with normal renal function group, the clinical stage of DN with insufficient renal function group. Patients in the same group were randomly allocated to the telmisartan treatment group, the SG treatment group, and the combination of SG and telmisartan treatment group, 68 in each group. Patients in the telmisartan treatment group took telmisartan tablet, 80 mg per day, once daily. Those in the SG treatment group took SG, 5 g each time, 3 times per day. Those in the combination of SG and telmisartan treatment group took telmisartan tablet (80 mg per day, once daily) and SG (5 g each time, 3 times per day). The therapeutic course for all was 3 successive months. SCr levels, serum urea nitrogen (BUN),24 h urine microalbumin (24 h U-MA) were detected before and after treatment. Results In three different treatment groups, 24 h U-MA decreased after treatment in the telmisartan treatment group; SCr and BUN decreased after treatment in the SG treatment group; and 24 h U-MA, SCr and BUN decreased after treatment in the combination of SG and telmisartan treatment group (P<0.05). In the clinical stage of DN with insufficient renal function group, SCr obviously increased after treatment in the telmisartan treatment group (P <0. 05). In the 3 DN stages, SCr and 24 h U-MA obviously decreased in the combination of SG and telmisartan treatment group, when compared with the telmisartan treatment group and the SG treatment group (P<0.05). Compared with the telmisartan treatment group, SCr and BUN obviously decreased in the SG treatment group, but 24 h U-MA quantitation obviously increased (P<0.05). BUN obviously decreased in the combination of SG and telmisartan treatment group (P<0. 05).

CONCLUSIONThe combination of SG and telmisartan could decrease urinary albumin, and stabilize SCr levels.

APOBEC(apolipoprotein B mRNA-editing enzyme catalytic-polypeptide) family members were reported as innate immune molecules with anti-viral activity for many viruses, such as HIV and HBV.In order to understand the function of APOBEC, the APOBEC-3F and-3G were cloned, expressed, and the sub-cellular localization of them was detected.The genes of APBEC-3F and-3G were cloned from PHA-stimulated PMBC and expressed in the MDCK cell by transfection.The sub-cellular localization of APOBEC-3F and-3G were detected by immunofluorescence.APOBEC-3F and-3G were cloned by RT-PCR and confirmed by DNA sequencing.The immunofluorescence indicated APOBEC-3F and-3G were located in the cytosal.APOBEC-3F and-3G could inhibit HBV replication effectively in HepG2.2.15 cell.APOBEC-3F and-3G could not be trans-located into nuclear by nuclear location signal(NLS) or bi-NLS(B-NLS).These results will help the future research on the function of APOBEC.

AlM: To compare the different formulas in intraocular lens(lOL) power calculations on high myopia after LASlK with cataract patients who received the phacoemulsification and intraocular lens implantation ( Phaco+lOL) .
METHODS:This was a retrospective study. Data from 102 eyes of 61 cataract patients with high myopia, who received Phaco+lOL after LASlK, were collected. Patients were divided into three groups by formulas in lOL power calculations before surgery: Holladay group ( 11 cases, 21 eyes), Haigis-L group (30 cases, 47 eyes) and SRK-T group (20 cases, 34 eyes). The ratios of equivalent lOL power after LASlK were predicted and the accuracy of their predictions were compared 3mo after surgery. lt was an index of reliability of the formulas outcomes.
RESULTS:The ratios of equivalent lOL power after LASlK using the Holladay, Haigis-L and SRK-T formulas were 0. 86 ± 0. 41D, 0. 43 ± 0. 30D and 1. 27 ± 0. 58D, respectively . There was no significant difference between Holladay group and SRK-T group ( t=-0. 271, P=0. 625>0. 05 ). However, significant difference was found between Haigis-L group and Holladay group ( t=2. 249, P=0.047<0. 05), Haigis-L group and SRK-T group (t=6. 012, P=0. 031<0. 05).
CONCLUSlON:The Haigis-L formula is more accurate than the SRK-T and Holladay formulas in predicting lOL power for cataract patients with high myopia after LASlK.

AIM:To observe the pathological changes of the lower segment of nasolacrimal duct mucosa in rabbits at different stages after retrograde lachrymal dilated drainage tube implantation.
METHODS:Totally 14 New Zealand rabbits were used in the present study. One side of nasolacrimal duct was obstructed to produce an experimental model and operated the reverse implantation of nasolacrimal duct intubation. Histological changes of the lower segment of nasolacrimal duct mucosa were observed by routine light microscope at 2, 4, 6, 8, 10, 12 and 14wk after the operation.
RESULTS: Compared with the control side, the group of 2 and 4wk after surgery presented the inflammatory cytokine. The group of 12wk after the operation presented isolated granuloma. Group 12 and 14wk presented scattered granuloma. The size of the granulomas was smaller and the density of epithelioid cell and fibroblast were lower in group 12wk than those in group 14wk by HE and Masson trichrome stain.
CONCLUSION:Recurrent Silicone Tube is used to treat nasolacrymal duct obstruction. Nasolacrimal duct can be narrowed and blocked again by granuloma, progressive fibrosis and adhesion of surrounding tissues when tube is in the duct more than 12wk.

Objective To investigate the effects of ozone (O3) on Wnt/β-catenin signaling pathway in the articular cartilage of rats with osteoarthritis (OA).Methods Eighteen male SPF Wistar rats,aged 3 months,weighing 200-250 g,were randomly divided into 3 groups (n =6 each) using a random number table:control group (group C),group OA,and O3 group (group O).OA was induced by injection of monosodium iodoacetate 3 mg (50 μl) into the right knee joint cavity.On 7th day after the model was established successfully,25 μg/ml O3 1 ml were injected into the knee joint cavity,once a week for 3 consecutive weeks in group O.Behavioral changes were observed after establishment of the model.At 1 day before establishment of the model,and 1,4,7,14,21 and 28 days after establishment of the model,the mechanical paw withdrawal threshold (MWT) was measured.At 28 days after establishment of the model,the total knee joint was removed and stained with haematoxylin and eosin for examination of the pathological changes of the cartilage (under light microscope) and for determination of the expression of β-catenin and matrix metalloproteinase-13 (MMP-13) in the cartilage (by immunohistochemistry).Results The signs of OA such as hind-limb motor dysfunction,knee joint swelling,or decreased joint motion,and signs of hyperalgesia such as lickings were observed after establishment of the model in rats.Compared with group C,the MWT was significantly decreased at each time point after establishment of the model,and the ex pression of β-catenin and MMP-13 in the cartilage was significantly up-regulated in the other two groups(P＜0.05).Compared with group OA,the MWT was significantly increased at 7-28 days after establishment of the model,and the expression of β-catenin and MMP-13 in the cartilage was significantly down-regulated in group O (P＜0.05).The pathological changes of the cartilage were significantly reduced in group O as compared with group OA.Conclusion The mechanism by which O3 mitigates OA is probably related to inhibition of Wnt/β-catenin signaling pathway activation in the articular cartilage in rats.
