OBJECTIVETo study the clinical significance of hepatitis B surface antigen (HBsAg) levels and HBsAg/hepatitis B virus (HBV) DNA ratio in relation to liver inflammation in HBeAg-positive chronic hepatitis B (CHB).

METHODSOne hundred and fifty-three Chinese patients with chronic HBV infection with HBeAg-positive status were enrolled in the study.Quantitative measurements were made for HBsAg levels by immunoassay (Architect HBsAg QT by Abbott Diagnostic) and HBV DNA by real-time fluorescence quantitative PCR.Levels of liver function markers were measured by standard methods.Liver biopsy specimens were obtained from all patients and used to score the histology (liver inflammation) activity index (HAI) and grade (G) the extent of necroinflammation.Statistical correlation analysis was performed to determine the association of HBsAg titre or HBsAg/HBV DNA ratio with the various parameters of liver injury.

RESULTSHBsAg titre and HBsAg/HBV DNA ratio were significantly correlated (r =0.578, P less than 0.0001).A significant positive correlation (r =0.642, P less than 0.0001) was found between HBsAg titre and HBV DNA load, and a significant negative correlation was found between the HAI and HBsAg (r =-0.389, P less than 0.0001) and HBsAg/HBV DNA ratio (r =-0.307, P=0.000l).A significant positive correlation was found between alanine aminotransferase (ALT) level and the HAI (r =0.480, P less than 0.0001).Patients with G less than 2 necroinflammation had significantly higher HBsAg titre and HBsAg/HBV DNA ratio than patients with G more than or equal to 2 necroinflammation (both P less than 0.01) but similar levels ofHBV DNA.Generation of a receiver operating characteristic curve using G more than or equal to 2 as the positive index provided the following area under the curve (AUC) values:HBsAg titre, 0.700; HBsAg/HBV DNA ratio, 0.672; ALT level, 0.713.When the random chance AUC was 0.5, all levels of AUC were statistically significant (Pless than 0.001).HBsAg titre (sensitivity =76.92%) was more sensitive than ALT level (sensitivity =76.92%), and HBsAg/HBV DNA ratio (specificity =81.33%) was more specific than ALT level (specificity =81.33%).Youden's index for comprehensive evaluation using ALT was higher than those for HBsAg titre or HBsAg/HBV DNA ratio.When HBsAg and ALT were considered in parallel, the sensitivity increased to 94.08% and specificity rose to 85.60%.

CONCLUSIONHBsAg titre, HBsAg/HBV DNA ratio and ALT levels can be used as the index for judging the degree of liver inflammation in HBeAg-positive CHB patients.Higher sensitivity and specificity are attained when HBsAg and ALT are used in series or parallel.

GATA transcription factor family members have been found to involve in the growth and differentiation of mammary gland. Among them GATA-3 is regarded as the most critical regulator involving the tumorigenesis of breast cancer (BC). Recently, trichorhinophalangeal syndrome-1 gene (TRPS-1), a new GATA family member, has been identified to be highly prevalent in breast cancer. Compared with ER-negative breast cancer, the expression of TRPS-1 is higher in ER-positive breast cancer and was significantly correlates with estrogen receptor, progesterone receptor, and GATA-3, indicating it may serve as a ductal epithelial cell-specific regulator in the differentiation of breast ductal epithelial cells. Studies have shown that miR221/222 is able to downregulate the expression of an epithelial cell marker E-cadherin by targeting TRPS-1, resulting in mammary epithelial cells transition to mesenchymal cell (EMT). In addition, it has been well accepted that, and the Science and Technology Bureau of Jiaxing (2012AY1071-2)TRPS-1 plays a role in the differentiation of several other cell types including kidney nephric mesenchymal cells, columnar chondrocytes, and osteoclasts, indicating that TRPS-1 involves in mesenchymal-to-epithelial cell transition (MET). In this article, we summarize the roles of GATA transcription factor TRPS-1 in ductal epithelial cells and the roles of its gene and protein expressions in predicting the prognosis of breast cancer.

OBJECTIVETo explore the clinical techniques and effects of repairing skin defects of the forefoot by free perforating flap nourished by peroneal artery.

METHODSFrom June 2007 to June 2011, 11 patients with skin and soft tissue defects of the forefoot were repaired by free peroneal artery perforating flap in emergent or subemergent. There were 10 males and 1 female with an average age of 28.6 years old ranging from 23 to 46 years old. Among them, 4 cases injured for traffic accidents, 3 for crush and 4 for machine strangulation. In all cases, the defect area of forefoot tissue varied from 2.0 cm x 4.0 cm to 4.0 cm x 8.5 cm,and the adopted area varied from 2.5 cm x 4.5 cm to 4.0 cm x 9.0 cm. The operation time was from 6 to 96 h (averaged 31.8 h). The blood vessels were anastomosed end-to-end.

RESULTSAll of the transferred free flaps survived uneventfully. Nine of them were successfully followed up from 6 to 24 months. The appearance, elasticity and functions of flaps were satisfied accompanied with slight damage of donor site although seemed bloated. The smaller donor site could be intimately seamed if necessary.

CONCLUSIONThe vessels anatomy of knee with antegrade extended peroneal artery was relative constant with a moderate thickness and simple operation, is useful to repair small or middle areas of skin defects in forefoot.

This study is to investigate effects of genistein on rat femoral bone metabolic in vitro. Rat femoral tissues was isolated and randomly divided into two groups including control group and genistein (1 x 10(-5) mol x(-1)) group. Determinations of alkaline phosphatase (ALP) activity, calcium content and osteoprotegerin (OPG), type I-collagen (Collagen-I), RANKL, Runx-2 and bone morphogenetic protein (BMP-2) mRNA expression were done by real-time PCR. The results showed that 1 x 10(-5) mol x L(-1) genistein could increase the activity of ALP and contents of Ca, regulate bone metabolism activity of OPG, RANKL, BMP-2, Collagen-I and Runx-2 mRNA expression level. Genistein can significantly modulate bone metabolism related gene expression level of rat femoral tissue in vitro, and can increase calcium content and the activity of ALP.

This study is to compare the effects of kaempferide and anhydroicaritin on biomineralization of rat osteoblasts (ROB) in vitro. Calvarias were dissected aseptically from newborn SD rats, the osteoblasts were obtained by enzyme digestion and were cultured in MEM containing 10% FBS. The medium was changed every three days, and serial subculture was performed when cells covered with 90% of the dish. Kaempferide and anhydroicaritin were separately added with final concentrations of 1 x 10(-4), 1 x 10(-5), 1 x 10(-6) and 1 x 10(-7) mol x L(-1) under the conditions of osteogenic differentiation. The proliferation was measured by MTT, and the optimal concentration was detected by the ALP activity at the 9th day after osteogenic induction culture. The osteogenic indexes of kaempferide, anhydroicaritin and control group with the optimal concentration were compared. The result showed that the anhydroicaritin at concentration of 1 x 10(-5) mol x L(-1) had significantly promoted the activity of ALP, calcium content and osteocalcin content, increased the number of CFU-F(ALP) and mineralized nodules, enhanced the mRNA level of BMP-2, OSX and Runx-2, which are key genes of osteogenic differentiation, and raised the protein content of collagen-I. However, the kaempferide group had not significantly represented the ability that promoted osteogenic differentiation of ROB. The difference of osteogenic differentiation on ROB between kaempferide and anhydroicaritin was caused by the prenyl group on C-8 of icariin.

OBJECTIVETo evaluate the synergistic effects of tetrandrine (TET) on the antifungal activity of topical ketoconazole (KCZ) in the treatment of dermatophytoses.

METHODSThe minimum inhibitory concentrations (MICs) for KCZ and combined KCZ and TET were compared in vitro. A randomized, double-blind trial was conducted among 97 patients with dermatophytoses who were assigned to 3 groups and received: treatment with combination of 2% KZC and 2% TET cream (KCZ + TET group), or only 2% KZC cream (KCZ group), or 2% TET cream (TET group). Patients with tinea corporis and/or tinea cruris were treated for 2 weeks, separately. The patients with tinea pedis and/or tinea manuum were treated for 4 weeks.

RESULTSCompared with KZC alone, combined use of KZC and TET showed lower MICs against clinical isolates of dermatophytes (P<0.05 for all). In the patients with tinea corporis and/or tinea cruris, the rates of overall cure (clinical cure plus mycologic clearance) were 81.25% vs. 33.33% for combined treatment and KZC monotherapy, respectively, after 4 weeks. All clinical indices were significantly different between the combination therapy and only KCZ therapy groups (P<0.05). Among the patients with tinea pedis and/or tinea manuum after 4 weeks treatment, the overall cure rates in the KCZ + TET group and KCZ group were 75.00% vs. 40.00%, respectively. In the KCZ + TET group, all the clinical indices were significantly better than those in the KCZ group and TET group (P<0.05). The rates of overall efficacy in the TET group were all zero. No local skin redness or itching was observed during TET treatment. No clinically significant changes were found in post-treatment routine blood, urine, or stool tests, ECG, or tests for liver and kidney function; no serious adverse events occurred.

CONCLUSIONTET synergistically enhanced the clinical efficacy of topical KZC cream in the treatment of dermatophytoses.
