BACKGROUND: T-type or linear type external fixator is applied in transcervical fracture in the elderly. Because its fixing force is weak, so it is difficult to avoid the aggravation of complication due to long term lay up in severe osteoporosis. Based on this reason,percutaneous penetrating arch tri-claw external fixator is designed to treat elderly transcervical fracture with strong fixing force for the realization of early restoration to the active status before injury to reduce complication.OBJECTIVE:To design pereutaneous penetrating arch tri-claw external fixator for the treatment of elderly transcervical fracture for the investigation of its feasibility.DESIGN: A self-controlled study by employing patients as subjects.SETTING: Department of orthopedic surgery of the first affiliated hospital of a universityPARTICIPANTS: Thirty-one cases of elderly transcervical fracture including 18 males and 13 females aged between 71 and 86 years old with an average age of 79 years were admitted by the Department of Orthopedics of the First Affiliated Hospital of Nanhua University between December 2002 and June 2004.METHODS: Percutaneous penetrating arch tri-claw external fixator was applied in the treatment of 31 cases with elderly transcervical fracture for the observation of its clinical effects, and the force-bearing situation and stability of the external fixator during application were analyzed by theoretical mechanics.MAIN OUTCOME MEASURES: ① The functional effects of percutaneous penetrating arch tri-claw external fixator applied in the therapy of transcervical fracture(sub-femoral head type,transcervical type and femoral basilar type); 2② The force-bearing situation and the stability of the fixing point on the fixator; ③ The restoration of activity in hip joint and fracture union time RESULTS: ① Patients could sit and stand immediately after the applicationof the fixator, and its fixing reinforce was analyzed by theoretic mechanics during standing(the force on upper fixing point A, B or C was 1/22, 1/2 or 1/2 of the lower fixing point) . The unidirectional flexion and extension activity of the hip joint overcame hip-inversion and rotational disposition at the distal end of the fracture. The hip-joint axial compression board caused compact embedment and insertion of the fracture end and vertical crush to simulate fracture union by stability and compressive strain. ② The stability of percutaneous penetrating arch tri-claw external fixator: No disposition was found during the application except rotational disposition during activity in sub-femoral head type fracture. The fixation was stable, the operative trauma was less,and the operation was simple with good accommodation. No complication was found due to long-term lay up and no re-disposition due to the loosening of the external fixator was found. ③ The hip-joint flexion-extension function was restored within 7 days averagely and fracture healing time was about 2 to 3 months, average of 2.4 months.CONCLUSION: No re-injury is found dter the application of percutaneous penetrating arch tri-claw external fixator, which has small force bearing at upper fixing point with strong stability. There is strain stimulation on the cross section of the fracture to promote fracture healing. The articular function status before injury could be restored at early stage.

Objective To investigate the effect and mechanism of liver cancer derived mesenchymal stem cell (LCMSC) on the invasion of liver cancer cells. Methods The expressions of interleukin (IL)-6, IL-8 and chemotactic factors CXCL1, CXCL5 and CXCL12 mRNA in the bone marrow derived mesenchymal stem cell (BMSC) and LCMSC were detected by reverse transcription-polymerase chain reaction (RT-PCR). The expression of protein CXCL12 in the supernate of LCMSC was detected by enzyme-linked immunosorbent assy (ELISA) and Western blot. Different cells were co-cultured and divided into the HepG2+BMSC, HepG2+LCMSC and HepG2+LCMSC+siRNA-CXCL12 groups. The effect of CXCL12 on the invasion of liver cancer HepG2 cells were detected by Transwell migration assay. The experiment data were compared using one way analysis of variance and LSD-t test or t test. Results The expression of CXCL12 mRNA in LCMSC was 60.3±2.4, significantly higher than 13.8±1.8 in BMSC (t=15.68, P<0.05). The expression of protein CXCL12 in the supernate of LCMSC was (31.5±1.7) ng/L, significantly higher than (14.3±1.5) ng/L in BMSC (t=7.60, P<0.05). And the expression of protein CXCL12 was up-regulated. Transwell migration assay indicated that the quantity of membrane-invasion cells in the HepG2+LCMSC group was 110±12, significantly higher than 65±9 in the HepG2+BMSC group and 76±7 in the HepG2+LCMSC+siRNA-CXCL12 group (LSD-t=5.25, 4.86; P<0.05). Conclusion CXCL12 is highly expressed in LCMSC. LCMSC may enhance the invasion of HepG2 cells through up-regulating the expression of CXCL12. The invasion of liver cancer cells can be effectively weakend by silencing the CXCL12 gene with siRNA.

ABSTRACT OBJECTIVE To investigate the children's medication information in β-lactam antibiotics's in children's hospitals in multiple regions, and to provide reference for further improving the drug information in the instructions of β lactam antibiotics. METHODS Collecting 847 drug instructions of β-lactam antibiotics in twenty children's hospitals in China, medication information labeling in drug instructions on children was investigated and analyzed. RESULTS After excluding duplicates, a total of 396 antibacterial drug inserts were obtained, involving 62 varieties, including 12 penicillins(59 copies), 27 cephalosporins(201 copies), etc. But there was two antibacterial drug for children only and up to 376 drugs for children and adults. In all drugs, there were 284 injections(71.72%) and 112 oral preparations(28.28%), among which the most suitable dosage forms for children were dry suspension(24.11%), granules(23.21%) and chewable tablets(4.46%). The annotation rates of children's indication, children's usage and dosage, children's drug guidance, pharmacokinetics in children, children's adverse reactions(396 categories) were respectively 27.78%, 93.69%, 64.65%, 39.14%, 20.96%, respectively. In oral dosage forms, the labeling rate of children's indications was 32.14%, the labeling rate of children's usage and dosage was 95.53%, the labeling rate of medication items for children was 58.93%, among them there were significant differences in the precautions and adverse reaction labeling rates between oral preparation and injections(P<0.05). There was not much difference in the labeling of pediatric medication information between domestic drugs and foreign-related drugs, but there was significant difference in the information labeling of precautions(P<0.05). There was no significant difference in the labeling rate of children's medication information among the seven regional children's hospitals. CONCLUSION There are few pediatric-specific β-lactam antibiotics, and the labeling information for pediatric use in their respective instructions is often incomplete and insufficient to provide meaningful guidance. Relevant departments should pay attention to the incomplete mark of drug use for children, improve the medication information of children in the instructions, and ensure the safety of pediatric drug use.

Hepatocellular carcinoma is the most common malignancy of the liver and poses serious health burdens on China and the whole world. However， most patients with hepatocellular carcinoma are already in the advanced stage at the time of diagnosis， with fewer opportunities for surgery and limited treatment options. In recent years， the advances in molecular targeted therapies have brought new hope for patients with advanced hepatocellular carcinoma. Among these therapies， lenvatinib is the second first-line drug after sorafenib approved by the US Food and Drug Administration for the treatment of advanced hepatocellular carcinoma， and it has attracted widespread attention for its powerful anti-tumor properties. However， the efficacy of lenvatinib is severely limited by its drug resistance. This article reviews the research advances in the molecular mechanisms of lenvatinib resistance in hepatocellular carcinoma and discusses possible ways to improve the efficacy of lenvatinib， so as to improve its efficacy.
