Objective:To study the hemostasis effect of the ingredients in compound hemostasis patches .Methods:The effect of the ingredients in compound hemostasis patches on the clotting time was studied by the coagulation of rabbit whole blood in vitro.The models of femoral arterial injury in rats and perforation of femoral artery in pigs were established , and the effect of the ingredients in compound hemostasis patches on the bleeding time and the bleeding loss was studied .Results:The results of the whole blood coagula-tion in vitro showed that the clotting time of the three compound hemostasis patches at different concentrations and thrombin group was significantly shorter than that of the blank control group and the saline control group (P<0.01).Compared with to the blank control group, the results of rat femoral artery trauma model test showed that the three patch groups and thrombin group could significantly re -duce the bleeding loss and bleeding time (P<0.05 or P<0.01).The results of pig femoral artery perforation hemorrhage model test showed that the compound hemostasis patches could significantly reduce the bleeding time (P<0.05).Conclusion:Compound hemo-stasis patches can significantly shorten clotting time and decrease bleeding loss .

To report a case of cutaneous and subcutaneous coinfection caused by Lichtheimia corymbifera and Candida parapsilosis.A 67-year-old female peasant consulted about proliferative granuloma developing on her left forearm after topical application of a Chinese herbal drug and splint fixation for the treatment of suspected fracture of the wrist.Direct microscopic examination showed gram positive budding yeast cells in lesion secretions.Pathological study with periodic acid-Schiff (PAS) and gormori methenamine silver (GMS) staining revealed broad non-separate hyphae in the corneum and dermis.Fungal culture of lesional tissue at 35℃ grew both mould and yeast.The mould was identified as Lichtheimia corymbifera based on morphological findings and sequences of the internal transcribed space (ITS) 1-4 regions.Thermal tolerance study revealed that the isolate grew fast at 37℃ but slowly at 40℃.Under a scanning electron microscope,the acrogenous sporangia were pear-shaped with conical sporangiophores originating from the top of stolon,which were among but not opposite to the rhizoids.The yeast was identified as Candida parapsilosis by Chromagar test and D1/D2 region sequencing.As antimicrobial susceptibility test indicated,the Lichtheimia corymbifera isolate was most sensitive to terbinafine and itraconazole.The proteolytic activity of Lichtheimia corymbifera was higher than that of Candida parapsilosis.The granuloma completely subsided after surgical resection and 6-week treatment with oral itraconazole 200 mg twice a day.No recurrence was observed during a 4-year follow-up.

BACKGROUND: Endoplasmic reticulum (ER) stress has been proved to be related to the occurrence of diabetes, dilated cardiomyopathy and neurodegenerative diseases. Indeed, it is closely associated with osteoarthritis. OBJECTIVE: To explore the effect of ER stress on the chondrocyte viability as well as the occurrence and development of osteoarthritis in rats. METHODS: Rat chondrocytes were isolated and cultured, and the ER stress in the rat chondrocytes was by 10 mg/L tunicamycin. The expression levels of ER stress markers C/EBP-homologous protein and 78 kDa glucose-regulated protein were detected by western blot assay, and the proliferation and apoptosis of chondrocytes were detected by cell counting kit-8 assay and AnnexinV-FITC flow cytometry, respectively. In the in vivo experiment, 15 Sprague-Dawley rats were selected and subjected to anterior cruciate ligament transection and medial meniscectomy to establish an animal model of osteoarthritis. Tunicamycin, tauroursodeoxycholic acid and PBS (blank control group) were respectively injected into the articular cavity, and then the progression of osteoarthritis was assessed by hematoxylin-eosin staining at 4 weeks after treatment. RESULTS AND CONCLUSION: After addition of tunicamycin, the expression levels of C/EBP-homologous protein and 78 kDa glucose-regulated protein were significantly upregulated, the viability of chondrocytes was decreased gradually, while the apoptotic rate was increased significantly. Results from gross observation and hematoxylin-eosin staining suggested that tunicamycin promoted the progression of osteoarthritis and tauroursodeoxycholic acid delayed the deterioration of cartilage in the rats. These findings indicate that ER stress results in the decreased chondrocyte viability and increased apoptosis, which may be an important pathogenesis of osteoarthritis. Additionally, tauroursodeoxycholic acid can effectively alleviate osteoarthritis induced by ER stress.

OBJECTIVETo study the possibility and mechanism of construction of tissue engineered bone with human bone marrow mesenchymal stem cells (hBMSCs) as seeding cells and partially demineralized bone matrix (pDBM) as scaffold.

METHODShBMSCs are cultured and mutiplified. The 4th grade hBMSCs are seeded on the pDBM, the growth and adhesion of hBMSCs on pDBM are observed under scanning electro microscope. The adhesion efficiency is assessed. The complexes are implanted in the nude mice subcutaneously, the pDBM without cells as control. The grafts are taken out on the 8th and 12th week.

RESULTSThere is new bone formation on the 8th and 12th week in complex group. There is a layer of osteoblast like cells adhered on the surface of most of the new bone, which suggest the possibility of intramembranous ossification. There is no bone formation in control group.

CONCLUSIONSTissue engineered bone can be constructed with hBMScs and pDBM in vivo, and the mechanism of which could be intramembranous ossification.

Aim To determine whether 8-bromo-7-me-thoxychrysin ( BrMC) inhibits in vitro carcinogenicity via up-regulating miR-519d expression and down-regu-lating Twist1 expression in liver cancer stem-like cells ( LCSLCs) derived from SMMC-7721 cell line. Meth-ods The second generation spheroids derived from SMMC-7721 cell line were obtained by sphere-forming assay and were considered as LCSLCs . Then LCSLCs were treated with various concentrations ( 1.0, 3.0, 10.0 μmol·L-1) of BrMC. The expression level of miR-519d was detected using real-time PCR. And in vitro carcinogenicity was investigated by sphere-forming assay and clone-forming assay in agar. The transcrip-tional activity and protein expression of Twist1 were an-alyzed using luciferase reporter assay and Western blot. Moreover, the molecular mechanism of BrMC was elucidated via miR-519 mimic transfection and Twist1 gene transduction, respectively. Results Compared with SMMC-7721 cells, miR-519d-3p was low-ex-pressed and Twist1 was over expressed in LCSLCs. And the sphere-forming ratio and the clone-forming ra-tio decreased by treatment with BrMC ( 1.0, 3.0, 10.0 μmol·L-1) in a dose-dependent manner. Fur-thermore, luciferase reporter assay demonstrated miR-519d could directly target the 3′ untranslated region of Twist1 mRNA and regulate protein expression. miR-519d mimic enhanced the effects of BrMC (3.0 μmol ·L-1) . However, Twist1 gene transduction effective-ly reversed the effects of BrMC ( 3.0 μmol·L-1) . Conclusion BrMC inhibits in vivo carcinogenicity via regulating miR-519/Twist1 signal axis in LCSLCs de-rived from SMMC-7721 cell line.

OBJECTIVETo discuss the influence of the rhizome of Cibotium barametz on the heamorheology index in mice with adjuvant arthritis and to compare the effect of raw medicinals with that of the processed ones.

METHODMice was injected with Freund's complete adjuvant on the rihgt behind foot to make model of adjuvant arthritis (AA). Hydroxyacrbamide tablets were orally administrated by mice with AA to make model of AA due to deficiency in the kidney (DK-AA). And then we determined the heamorheology index of the normal group, positive control group, AA group, DK-AA group and medicinals-treated groups.

RESULTIn the groups of AA, and DK-AA, the heamorheology index, such as high shearing, middle shearing, low shearing, plasma viscosity, whole blood reduction viscosity, erythrocyte aggregation exponent, erythrocyte degeneration exponent, sedimentation, sedimentation equation K value, erythrocyte rigidity exponent, erythrocyte electrophoresis time, casson viscosity, casson yield stress, increased significantly. After treated with Cibotium barametz, the heamorheology index except red blood count, packed cell volume, fibrinogen decreased obviously to get normal.

CONCLUSIONRhizome of Cibotium barametz could promote heamorheology in mice with AA and DK-AA to exhibit effect of promoting blood circulation and remove blood stasis. The medicinal rhizomes processed with sand have the effect enhanced.
