Objective To investigate the effect of tea polyphenols (TP) on renal damage in rats model induced by D-galactose. Methods Rats were injected with D-galactose (150 mg/kg?d),ip for 8 w,to induce renal damage. From the 3rd week,TP (150,75,37.5 mg/kg?d),aminoguanidine (150 mg/kg) and vitamin E (150 mg/kg) were administered with D-galactose for 6 w. After treatment,fasting blood glucose and 2 h blood glucose in oral glucose tolerance test were measured. The levels of HbA1C and fructosamine in serum,the activity of aldose reductase and content of advanced glycation end products (AGEs) in plasma and in kidney tissues and the activity of SOD,GSH-Px,and the contents of MDA in kidney tissues were measured,and 24h urinary protein,blood urea nitrogen (BUN) and serum creatinine (Cr) were detected. The apoptosis of renal cells were detected by flow cytometer. Results After treatment of D-galactose for 8 w,2h glucose level in oral glucose talerance test was increased significantly,the activity of aldose reductase and the content of AGES were increased significantly in blood. The levels of AGEs and MDA in renal tissues were also enhanced significantly. However,the activities of SOD and GSH-Px decreased. Additionally,the contents of 24h urine protein,BUN,Cr and the apoptotic rate of renal cells were increased significantly. High and middle dose of TP could can decrease the activity of aldose reductase in red blood cells,and inhibit the formation of glycation products in model rats induced by D-galactose. Also,TP could enhance the antioxidative activities and decrease the contents of AGEs and MDA in renal tissues. Mesnwhile,24h urine protein,BUN and Cr and the apoptotic rate of renal cells were increased significantly. Conclusion TP can inhibit glycation reaction induced by D-galactose and then protect renal from damage caused by glycation.

AIM: To determine the association between subfoveal choroidal thickness before therapy and therapeutic activity in diabetic macular edema.
METHODS: The current study was a retrospective study, which included 32 patients ( 32 eyes ) diagnosed with diabetic retinopathy and macular edema. All the patients were firstly treated with intravitreal injections of ranibizumab. Main outcome measures were included the subfoveal choroidal thickness, central macular thickness and best-corrected visual acuity ( BCVA) at preoperation and postoperative visit at 3mo.
RESULTS: After 3 monthly intravitreal injections of ranibizumab, the BCVA was significantly higher than that before therapy and accompanied with significantly reduced thickness of subfoveal choroid and central fovea of macula. Spearman analysis was revealed that a greater baseline subfoveal choroidal thickness was associated with a better BCVA (rs=0. 544, P=0. 036).
CONCLUSION:In the therapy of intravitreal injections of ranibizumab on diabetic macular edema, there seems to be a better BCVA in the patients with a greater baseline subfoveal choroidal thickness. Therefore, baseline subfoveal choroidal thickness may be a useful predictor for the therapy of diabetic macular edema.

This study aims to explore the impact on patient's liver and kidney function by different dosage of Kudiezi injection. This study retrospectively analyzed 15 228 patients' records from 18 nationwide general hospital information system (HIS). All patients were treated with Kudiezi injection, 1 956 patients that were given doses of > 40 mL, which is above the recommended dose, acted as the observation group. Fifty-five patients receiving the recommended dose of < 40 mL were the control group. Data about alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (Cr) and blood urea nitrogen (BUN) were collected before and after using Kudiezi injection, changes after treatment were outcomes. Also recorded were: age, costs, length of hospitalization and the patients' condition on admission. Propensity score method was used to balance 71 confounding variables such as gender, age, mortality, and costs. There were no significant difference on the four indexes between the two groups. It is hard to conclude that the use of Kudiezi injection over the recommended dose could influence the four indexes of liver and kidney from this data analysis. More conclusive evidence should be collected by further prospective study.

The incompatibility of traditional Chinese medicines is related to the clinical medication safety, so has attracted wide attentions from the public. With the deepening of studies on the incompatibility of traditional Chinese medicines represented by 18 incompatible herbs, the incompatibility of theory traditional Chinese medicines has raised to new heights. From the origin of incompatibility theory of traditional Chinese medicines, relationship of herbs, harms of incompatible herbs and principle of prevention to toxic effects of specific incompatible medicines, the innovation and development of the traditional Chinese medicine incompatibility theory was explored. Structurally, the incompatibility of traditional Chinese medicines refers to the opposition of two herbs based on seven emotions and clinical experience. The combination of incompatible herbs may lead to human harms, especially latent harm and inefficacy of intervention medicines. The avoidance of the combination of incompatible herbs and the consideration of both symptoms and drug efficacy are the basic method to prevent adverse reactions. The recent studies have revealed five characteristics of incompatible herbs. Toxicity potentiation, toxication, efficacy reduction and inefficacy are the four manifestations of the incompatible relations. The material changes can reflect the effects of toxicity potentiation and toxication of opposite herbs. The accumulation of toxicity and metabolic changes are the basis for latent harms. The antagonistic effect of main efficacies and the coexistence of positive and negative effects are the distinctive part of the incompatibility. The connotation of incompatible herbs plays an important role in the innovation of the traditional Chinese medicine incompatibility theory.

OBJECTIVETo observe the result of repairing deformity due to cicatricial contracture in face and neck regions with expanded skin flap.
METHODSEighty-three skin expanders with volume ranging from 100 to 600 mL were implanted into 38 patients with scars in face and neck regions after burn. The expansion time ranged from 3 to 5 months. Most expanders were implanted under normal skin. Ten expanders were implanted under stable integrated scars after healing of burn, and flaps therefrom were transplanted; 3 expanders were implanted into deep fascia layer of trapezius, and remote expanded skin flaps with deep branch of transverse cervical artery as the pedicle were formed and transplanted.
RESULTSAll flaps survived in 38 cases with satisfactory results. Complications including hematoma and infection after surgery occurred in 8 cases, but they did not affect therapeutic effect after treatment. Thirty patients were followed up for 3 to 24 months. It was found that the color and texture of skin flaps were good; appearance and function were obviously improved.
CONCLUSIONSExpanded skin flap is the best flap for repairing cicatricial deformity in face and neck regions after burn. Expanded cicatricial skin and expanded skin of remote region are good choices when normal skin is not available nearby.

Objective To retrospectively determine the features of stones and calcifications in hepatobiliary system on virtual nonenhanced (VNE) dual-energy computed tomography (CT), and to evaluate the possibility of VNE images in diagnosis for those lesions.Methods A total of 128 gall stones and calcifications of the liver found in 110 patients were examined with triple phase abdominal CT scan from July 2007 to December 2011, in which true nonenhanced (TNE) phase and arterial phase were performed with single-energy CT (120 kVp) and portal venous phase was performed with dual-energy CT (100 kVp and 140 kVp). VNE images were generated from the portal venous phase dual-energy CT data sets by using commercially VNC software. The mean CT values for the stone, liver, bile and paraspinal muscle, mean lesion density and size in area dimension, contrast-to-noise ratio (CNR) of lesion to the liver or bile, and image noise were assessed and compared between VNE and TNE images. The effective dose and size-specific dose estimate (SSDE) were also calculated.Results The mean CT values of the lesions measured on VNE images declined significantly compared with those measured on TNE images (164.51±102.13 vs. 290.72±197.80 HU, P<0.001), so did the lesion-to-liver CNR (10.80±11.82 vs.18.81±17.06, P<0.001) and the lesion-to-bile CNR (17.24±14.41 vs. 21.32±17.31, P<0.001). There was no significant difference in size of lesions area between VNE and TNE images (0.69±0.88 vs. 0.72±0.85 cm, P=0.062). Compared to the 128 lesions found in TNE images, VNE images showed the same density in 30 (23.4%) lesions, lighter density in 88 (68.8%) lesions, while failed to show 10 (7.8%) lesions, and showed the same size in 61 (47.7%) lesions and smaller size in 57 (44.5%) lesions. The CT cutoff values of lesion and size were 229.21 HU and 0.15 cm, respectively. The total effective dose for triple phase scan protocol with TNE images was 19.51±7.03 mSv, and the SSDE was 39.84±11.10 mGy. The effective dose for dual phase scan protocol with VNE images instead of TNE images was 13.29±4.89 mSv, and the SSDE was 27.83±9.99 mGy. Compared with TNE images, the effective dose and SSDE of VNE images were down by 32.05%±3.69 % and 30.63%±2.34 %, respectively.Conclusions Although the CT values and CNR of the lesions decreased in VNE images, the lesions of which attenuation greater than 229.21 HU and size larger than 0.15 cmcould be detected with good reliability and obvious dose reduction. There was good consistency in the size of stones and calcifications in hepatobiliary system between VNE images and TNE images, which ensured the possibility of the clinical application of VNE images.
