OBJECTIVE@#To observe effects of (, TLZT) gel preparation on p53, miR-502-5p, NF-κBp65 in synovial tissue of knee osteoarthritis (KOA), and to explore mechanism of TLZT gel preparation in treating KOA.@*METHODS@#Thirthy-six Wistar rats aged 8 weeks and weighed 200 to 220 g (meaned 208 g) were randomly divided into normal group, model group and traditional Chinese medicine (TCM) group, 12 rats in each group. KOA model was established by modified Hulth method. After 4 weeks of modeling, TCM group treated with TLZT gel preparation for external use, 3 times daily for 2 weeks;normal group and model group were fed normally without intervention. After treatment, morphological changes of specimens in each group were observed, changes of miR-502-5p in synovial tissue were detected by qPCR, and contents of p53, NF-κBp65, IL-1β, TNF-α, MMP-13 in synovial tissue were detected by qPCR and Western Blot respectively.@*RESULTS@#(1)Morphological observation of specimens showed that the articular cartilage in model group was hyaline and uneven, the synovial membranes were hypertrophic and proliferative with a large number of inflammatory cells infiltrating, the joint fluid was thicker in texture;the articular cartilage in TCM group was more transparent and smooth, synovial hyperplasia was mild with a small amount of inflammatory cell infiltration, the texture of articular fluid was clear and sparse. (2) Compared with normal group, content of miR-502-5p of synovial tissue in model and TCM group were increased, mRNA and expression of p53 decreased, expression of NF-κBp65, IL-1β, TNF-α, MMP-13 increased. (3)Compared with model group, content of miR-502-5p in synovial tissue of TCM group decreased (<0.05), mRNA and protein expression of p53 increased (<0.05), mRNA and protein expression of NF-κBp65, IL-1β, TNF-α, MMP-13 decreased (<0.05).@*CONCLUSION@#Expression of p53, miR-502 -5p, NF -κBp65 in synovial tissue is closely related to synovial hyperplasia and inflammatory reaction, TLZT gel preparation may reduce proliferation and inflammatory reaction of KOA synovium by regulating the expression of p53, miR- 502-5p, NF-κBp65 in synovial tissues.

Analysis of clinical characteristics in 45 cases of Diamond-Blackfan anemia / 中国实验血液学杂志

In order to explore the diagnosis and therapy of Diamond Blackfan anemia (DBA), the clinical data of 45 cases of DBA admitted in our hospital from February 1994 to July 2011 were analyzed retrospectively. The clinical characteristics, results of laboratory examination, treatment reaction and outcome of disease were investigated. The results indicated that out of 45 children diagnosed as DBA, 14 cases (31.1%) had short stature and physical malformation. All patients had anemia with reticulocytopenia. Thirty-four patients (75.6%) had mean corpuscular volume. Eleven patients (24.4%) had macrocytic anemia. Bone marrow examination showed a marked erythroid hypoplasia in all patients. Out of 29 cases tested for fetal hemoglobin (HbF), 13 cases (44.8%) had high level of HbF. Erythroid colony-forming unit of bone marrow was tested in 25 patients, among them 12 patients (48%) showed normal plasia, 13 (52%) showed hypoplasia. The erythropoietin (EPO) levels of 17 patients were elevated. Karyotypes were examined in 28 patients, and showed all normal. The treatment was based on corticosteroids and Cyclosporine A. Thirty patients had good response to corticosteroid therapy, and 10 of them obtained a sustained corticosteroid-induced remission. Twenty cases discontinued corticosteroid therapy after remission, as a result, 15 cases (75%) relapsed, moreover all the relapsed cases still had good response to corticosteroid. Two relapsed patients suffered from aplastic anemia, one of them died of therapy failure. Six patients were unresponsive to corticosteroid, 1 of which achieved remission with cyclosporine A and the others continued to receive regular transfusions. 3 patients received iron chelation therapy. It is concluded that the clinical characteristics, complete blood count, bone marrow smear, HbF level and EPO level are useful to make a diagnosis of DBA. Most patients have a good response to corticosteroid therapy, but relapse rate is high when drug was discontinued. Patients unresponsive to corticosteroid should receive regular transfusions and chelation therapy.

Effect of Huxin Formula on reverse cholesterol transport in ApoE-gene knockout mice / 中国结合医学杂志

<p><b>OBJECTIVE</b>To observe the effect of Huxin Formula on expressions of the chief reverse cholesterol transport (RCT) associated genes, caveolin-1 and scavenger receptor-BI (SR-BI) in ApoE-gene knockout [ApoE (-/-)] mice.</p><p><b>METHODS</b>Thirty ApoE (-/-) mice of 4-6 weeks old were randomly divided into three groups (A-C). After being fed with high-fat diet for 16 weeks, they were treated with HXF (1 mL/100 g), pravachol (0.3 mg/100 g), and saline in equal volume respectively for 16 weeks successively; in addition, a blank group was set up with 10 C57BL/6J mice of 6-week old received 16-week high-fat feeding and saline treatment. Animals were sacrificed at the termination of the experiment, their paraffin sections of aortic tissue were used to measure the size of plaque, expressions of cavolin-1 and SR-BI were detected by immunological histochemical method.</p><p><b>RESULTS</b>As compared with the blank group, levels of caveolin-1 and SR-BI were increased in Groups A and B (P<0.01); but the increase in Group A was more significant than that in Group B (P<0.05). The plaque/aorta area ratio decreased significantly in Groups A and B, but showed insignificant difference between the two groups.</p><p><b>CONCLUSION</b>HXF could obviously increase the expressions of RCT associated genes, caveolin-1 and SR-BI, promote the RCT process, so as to reduce the formation of aorta atherosclerotic plaque in ApoE (-/-) mice.</p>

Growth inhibition and induction of apoptosis in human oral squamous cell carcinoma Tca-8113 cell lines by Shikonin was partly through the inactivation of NF-kappaB pathway.

Shikonin, a naphthoquinone pigment isolated from the Chinese herbal therapeutic, Zicao, has been shown to exhibit antioxidant and anticancer effects. In this study, its ability to induce apoptosis in cultured Tca-8113 oral cancer cells was studied. Treatment of the Tca-8113 cells with a variety of concentrations of Shikonin (10-40 microm) resulted in dose- and time-dependent sequences of events marked by apoptosis, as shown by the loss of cell viability, chromatin condensation, internucleosomal DNA fragmentation and sub-G1 phase accumulation. Furthermore, apoptosis in the Tca-8113 cells was accompanied by the activation of protease caspase-8, -9, -3 and low expression of Bcl-2 protein. Interestingly, inactivation of the NF-kappaB pathway was found in shikonin-induced apoptosis in Tca-8113 cells. These results raise the possibility that the anti-tumor effects of Shikonin in Tca-8113 cells are at least partly through the inactivation of the NF-kappaB pathway and subsequent activation of protease caspase family. Pharmacological inhibition of the NF-kappaB activity by Shikonin might be a powerful treatment option for OSCC in which activation of NF-kappaB plays a critical role in tumor growth and progression.
