OBJECTIVETo evaluate the efficacy and safety of three antithrombotic agents on venous thromboembolism (VTE) after unilateral total knee arthroplasty.

METHODSFrom November 2011 to March 2014, 149 patients undergoing unilateral total knee arthroplasty for knee osteoarthritis were reviewed. Among them, there were 66 males and 83 females, ranging in age from 48 to 76 years old. All the cases were randomly divided into three groups including Aspirin group, low-molecular-weight heparin (LMWH) group, and rivaroxaban group, according to antithrombotic agents. Deep vein thrombosis (DVT), pulmonary embolism (PE) and bleeding complication (including wound ecchymosis, hematoma and other local complications, gastrointestinal, cardiovascular, urinary hemorrhage and other major bleeding events) of antithrombotic agents were observed and analyzed statistically at the 6 week, 8 week, and 12 week after operation.

RESULTSAmong patients who received Aspirin (48 cases), 4 patients had DVT, in 1 patient had PE, and 2 patients had bleeding complication. Among 54 patients in low-molecular-weight heparin group, 3 patients had DVT, 1 patient had PE, and 3 patients had bleeding complication. While among those patients received the rivaroxaban (47 cases), 3 patients had DVT, 0 patient had PE, and 11 patients had bleeding complication. There were no statistically differences among three groups on DVT, and PE (P>0.05). The incidence of bleeding complication in rivaroxaban group was higher than the other two antithrombotic agents, and the difference among the three groups was statistically significant (P<0.05).

CONCLUSIONAspirin, low-molecular-weight heparin, and rivaroxaban could effectively reduce the incidence of VTE after total knee arthroplasty, and their efficacy was similar. Rivaroxaban has a higher incidence of bleeding complication and further clinical trials are required to be conducted to assess the safety of rivaroxaban in clinical.

Objective To study collagen changes in dermis of hairless mice that were exposed to ultraviolet. Methods The hairless mice was irradiated under UVA, UVB and the combination of the two for 20 weeks, total dose of UVA was 222J/cm~2, and that of UVB was 5.9J/cm~2. After irradiation, the dorsal skin's collagens of animals were analysed by computer imaging analysis system, histopathologic examination, specific stains and electorn microscopy. Results The hairless mice exposed to ultraviolet A were unchanged in dermis collagen. The hairless mice was irradiated under UVB and the both UVA and UVB, and the content of collagen was decreased with less affinity for collagen staining. These findings were supported by electron microscopy, which showed fraying, thickened, and proliferating collagen, coalesced into extensive denaturalization. The ratio of types Ⅲ/Ⅰ+Ⅲ collagen was significantly increased. Conclusion The qualitative and quantitative changes of the collagen in the ultraviolet irradiated skin of hairless mice are related to ultraviolet B but not to UVA. UVB is a key factor of skin collagen damage in UV-irradiation.

Objective To study the changes of skin wrinkles in hairless mice while exposed to ultraviolet. Methods The hairless mice were irradiated under long-wave ultraviolet ray (UVA), medium-frequency wave ultraviolet ray (UVB) and the combination of the two for 20 weeks. Total dose of UVA was 222J/cm~2, and that of UVB was 5.9J/ cm~2. After irradiation, the skin wrinkling of animals were analysed by the naked eye, dermatoglyphics enlarges and applied color skin system of pathologic portrait quantitative analysis. Results Control group: The hairless mice skin were fine and delicate, the ditch and ridge of skin distributed even, and had no the obvious cornification. Long wave ultraviolet ray (UVA) set: The skin was slightly rough, skin ditch and ridge distributed still even, and had no obvious cornification; quantitative analysis had no the obvious difference from that of control group. Medium-frequency wave ultraviolet ray (UVB) set: The dermatoglyphics were disorderly, and the skin ditch deepened, widened, and the skin ridge increased the breadth and obvious cornification, and quantitative analysis had obvious difference from that of control group. Long wave and medium-frequency wave ultraviolet ray (UVA+ UVB) set: The dermatoglyphics was disorderly, and the skin ditch deepened, widened, the skin ridge increased the breadth, skin cornification was more obvious, quantitative analysis had obvious difference from that of control group. Conclusions The qualitative and quantitative changes of the wrinkles in the ultraviolet irradiated skin of hairless mice are related to ultraviolet B but not to UVA. UVB is a key factor of skin wrinkling in UV-irradiation.

Objective To promote the use of chemical peeling in facial rejuvenation with the phenol and croton oil peeling agents to the UVA/B-irradiated skin of hairless mice, and to provide the experimental evidence for the clinical application of the treatment of irradiated skin.Methods Sixty BALB/C hairless mice were photo-aged by use of chronic ultraviolet A and ultraviolet B irradiation for 20 weeks. After irradiation the animals were randomly divided into two groups:untreated (10 mice) and treated (50 mice). The phenol and croton oil chemical peeling agents were applied to the dorsal skin of treated animal group while it was full anesthetized. Punch biopsies were taken at 7, 14, 30, 60, and 90 days after peel for histological analysis. At 60 days after irradiation, the skin wrinkling of animals were analyzed by macroscopy, cleavage line amplification, and computer imaging analysis system. Results The treated areas of irradiated skin recovered rejuvenation and exhibited a unique connective tissue layer composed of fine collagen fibers beneath the epidermis. Conclusion The mixture of phenol-croton oil may reverses the visible stigmata of photoaging skin. Our results will be of great help to promote the use of chemical peeling in facial rejuvenation.

Salvia miltiorrhiza is a highly valued traditional chinese medicine for the treatment of atherosclerosis-related disorders in china, such as cardiovascular and cerebrovascular diseases in China. The wilt disease is serious in the culture of S. miltiorrhiza. Wilt disease cause biomass of plant shoots and roots is lessened, active components are decreased. To solve these problems, we research the pathogen causing wilt disease of S. miltiorrhiza. The suspected pathogen is identified by morphology and etiological test. The identification was further confirmed by alignment the sequences of internal transcribed spacer (ITS) amplified by PCR. Our result show the wilt disease of S. miltiorrhiza mostly occurred in July and August, which is hot and wetter. The wilt disease rate of S. miltiorrhiza continuous cropping for one year in S. miltiorrhiz stubble is 10%, but the wilt disease rate of S. miltiorrhiza continuous cropping for three years in S. miltiorrhiz stubble is 60%-70%. The root rot of S. miltiorrhiz caused by the wilt disease, so the wilt disease was mistaken for the rot root in production. Morphological characteristics show the pathogen is Fusarium oxysporum. The sequence of ITS wes determined and found by BLAST shared 99% identity to that of F. oxysporum f. sp. cucumerinum. So it comes to the conclusion that the causing agent of wilt disease on S. miltiorrhiza belongs to F. oxysporum.

We revisited the "Xiao Chaihu Decoction event (XCHDE)" occurred in late 1980s in Japan and the Bupleuri Radix related adverse drug reaction (ADR) reports in China After careful review, comparison, analysis and evaluation, we think the interstitial pneumonitis, drug induced Liver injury (DILI) and other severe adverse drug envents (ADEs) including death happened in Japan is probably results from multiple factors, including combinatory use of XCHDE with interferon, Kampo usage under modern medicine theory guidance, and use of XCHD on the basis of disease diagnosis instead of traditional Chinese syndrome complex differentiation. There are less ADE case reports related to XCHD preparation in China compared to Japan, mostly manifest with hypersensitivity responses of skin and perfuse perspiration. The symptoms of Radix Bupleuri injection related ADEs mainly manifest hypersensitivity-like response, 2 cases of intravenous infusion instead of intramuscular injection developed hypokalemia and renal failure. One case died from severe hypersensitivity shock. In Chinese literatures, there is no report of the interstitial pneumonitis and DILI associated with XCHDG in Japan. So far, there is no voluntary monitoring data and large sample clinical research data available. The author elaborated the classification of "reevaluation" and clarified "re-evaluation upon events" included the reaction to the suspected safety and efficacy events. Based on the current status of the clinical research on the Radix Bupleuri preparations, the author points out that post-marketing "re-evaluation upon suspected event" is not only a necessity of continuous evaluation of the safety, efficacy of drugs, it is also a necessity for providing objective clinical research data to share with the international and domestic drug administrations in the risk-benefit evaluation. It is also the unavoidable pathway to culture and push the excellent species and famous brands of TCM to the international market, in that it enhances the pharmaceutical manufactures the ability to control enterprise risk and eliminate the negative impact on traditional Chinese medicine. With the widely used and ADR report concentrated Radix Bupleuri injection as an example, the author provide a new approach to post-marketing clinical research.
