BACKGROUND:The proximal tibial fractures within joint are a common type of fracture, and clinical treatment is difficult. The implant internal fixation is a commonly used method of treatment. However, the choice of the optimal implant internal fixation is always the key problem in clinical research. OBJECTIVE:To explore the curative effect of different implant internal fixation for the treatment of intra-articular proximal tibial fractures and to obtain the better treatment through the comparative analysis. METHODS:A total of 32 patients of intra-articular proximal tibial fracture, who were treated with different implant internal fixation for the treatment of proximal tibia, were selected from the Department of Orthopedics, People’s Hospital of Zezhou County of Jincheng City and Second Affiliated Hospital of Shanxi Medical University from September 2010 to September 2013. These patients were divided into two groups according to fixation methods (n=16). Observation and control groups received LISS locking plate and common plate, respectively. The amount of bleeding, operation time and incision length were observed in both groups. Patients were fol owed up for 1 to 12 months after treatment so as to record fracture healing time, ful weight bearing time and excel ent and good rate and to observe the incidence of complications, including joint stiffness, loosening, nonunion and infection. RESULTS AND CONCLUSION:Incision length and operation time in the observation group were significantly shorter than that in the control group, and the amount of bleeding was significantly lower in the observation group than that of control group (al P<0.05). The healing of fracture and the ful weight bearing time were significantly shorter in the observation group than that in the control group (both P<0.05). The incidence of complications was significantly lower in the observation group (13%) than in the control group (46%;P<0.05). The total excel ent and good rate of repair was significantly higher in the observation group than in the control group (94%, 69%, P<0.05). These results confirm that compared with the traditional plate fixation, internal fixation with LISS locking plate for treating intra-articular proximal tibial fractures can get better therapeutic effects, greatly reduces the injuries to soft tissue and fracture blood supply, promotes fracture healing and restores joint stability.

BACKGROUND: Studies regarding Feridex in vitro cell labeling are mainly in rodents, while little information is known on primate crab-eating macaque.OBJECTIVE: To explore the feasibility of protocols using Feridex and transfection agents for in vitro magnetic labeling of bone marrow stromal cells (BMSCs) in crab-eating macaque.METHODS: Under the sterile condition, the crab-eating macaque BMSCs were obtained by means of density gradient centrifugation following a bone puncture. Feridex-poly-l-lysine complexes were used to magnetically label BMSCs. The efficiency and cellular viability of Feridex-poly-l-lysine labeled BMSCs were evaluated by Prussian blue staining, electron microscopy, and trypan blue dye exclusion test. The proliferation and differentiation ability of Feridex-poly-l-lysine labeling BMSCs were also investigated by inverted phase contrast microscope and immunocytochemistry. RESULTS AND CONCLUSION: BMSCs could be effectively labeled by Feridex and labeling efficiency was around 99%. Tiny blue stained fine particles and numerous vesicles coated with the electron-dense magnetic iron particles could be found in the cytoplasm of Feridex-poly-l-lysine labeled BMSCs under optical microscopy and transmission electron microscopy respectively. Cell viability, proliferation and differentiation ability of labeled BMSCs were not affected by Feridex-poly-l-lysine labeling. Results indicated that Feridex might be used to label BMSCs of crab-eating macaque.

Objective To analyze the gene expression profiles in relation to the migration ability of adult human bone marrow-derived neural stem cells (Md-NSCs), and identify the genetic basis of the high migration potential of Md-NSCs in the central nervous system (CNS). Methods Adult human bone marrow stromal celIs(BMSCs) obtained from adult healthy volunteers were induced to differentiate into Md-NSCs in vitro, and the expressions of the genes related to cell invasiveness and metastasis were investigated by microarray analysis. Quantitative real-time PCR (RT-PCR) was used to verify the microarray results. Results The results of microarray analysis revealed significant overexpressions of the genes MMP1, MMP2, MMP17, ITGA3, RhoB, RhoC and RhoD in the Md-NSCs as compared with the expressions in fresh normal human adult bone marrow cells depleted of red blood cells. Quantitative RT-PCR verified the overexpression ofMMP2 gene by 2.84×100 folds, ITGA3 gene by 2.22×102folds, and RhoC gene by 4.92×100 folds. Conclusion The high migration potential of the Md-NSCs in the CNS is probably associated with the overexpression of the genes that promote cell invasiveness and metastasis. These overexpressed genes are also important oncogenes, and therefore the tumorigenicity of the Md-NSCs warrants further investigation.

Purpose:
Platelet-related indices, including mean platelet volume (MPV) and plateletocrit (PCT), have been reported as new prognostic factors of overall survival (OS) in many cancers, but not yet in biliary tract cancer (BTC). We intended to assess these indices in predicting OS in BTC patients with the aim to build a new prognostic model for patients with BTC after surgical resection.
Materials and Methods:
Survival analysis and time receiver operating characteristic analysis were applied to screen the platelet indices. Univariate and multivariate Cox analyses were used to identify independent prognostic factors and develop a new prognostic model. Harrell’s C-statistics, calibration curves, and decisive curve analysis were used to assess the model.
Results:
MPV and platelet distribution width (PDW)/PCT showed the best prognostic accuracy among the platelet indices. In multivariable analysis, factors predictive of poor OS were presence of nodal involvement, Non-radical surgery, poor tumor differentiation, carbohydrate antigen 19-9 > 100 U/mL, MPV > 8.1 fl, and PDW/PCT > 190. The new model was found to be superior to the TNM staging system and our new staging system showed higher discriminative power.
Conclusion
MPV and PDW/PCT have high prognostic value in BTC patients, and the novel staging system based on these two indices showed good discrimination and accuracy compared with the American Joint Committee on Cancer 7th TNM staging system.

ObjectiveTo explore the mechanism of Xianglian Huazhuo prescription in the treatment of chronic atrophic gastritis (CAG) based on network pharmacology and animal experiments,so as to provide scientific basis for clinical application. MethodThe possible targets and pathways of Xianglian Huazhuo prescription in the treatment of CAG were obtained based on the prediction of network pharmacology. The CAG rat model was induced by sodium salicylate,N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and hunger and satiety disorder. Then the CAG rats were treated with Xianglian Huazhuo prescription and morodan for 60 days. After administration,the rats were sacrificed,and the content of interleukin-6 (IL-6),tumor necrosis factor-α (TNF-α),interleukin-1β (IL-1β) and vascular endothelial growth factor (VEGF) in serum was determined by enzyme linked immunosorbent assay(ELISA). In addition, the protein expression of Bad and Bcl-2 in gastric mucosa was detected by immunohistochemistry (IHC). ResultA total of 241 active components of Xianglian Huazhuo prescription and 53 core targets were obtained. Xianglian Huazhuo prescription affected multiple biological processes,such as cell proliferation and apoptosis,inflammatory reaction,regulation of DNA metabolism,and cell response to redox,as well as phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt),TNF,mitogen-activated protein kinase (MAPK),cancer and cancer-related signaling pathways. The animal model verification showed that Xianglian Huazhuo prescription lowered the levels of IL-6,TNF-α,IL-1β and VEGF in serum of CAG rats,and reduced the protein expression of Bad and Bcl-2 in gastric tissue. ConclusionXianglian Huazhuo prescription could regulate PI3K/Akt signal pathway and improve gastric mucosal injury in CAG by participating in biological processes such as cell proliferation,apoptosis and inflammation.

Terpine-4-ol is abundant in nature. As a cyclic monoterpenoid compound, terpine-4-ol is distributed in a variety of natural plants. It is the main component and the key active substance in many traditional Chinese essential oils, such as Melaleuca alba essential oil and coral ginger essential oil. Terpine-4-ol has anti-microbial, anti-tumor, insecticidal, anti-inflammatory, and other effects. It can treat cancer, as well as oral and cardiovascular diseases with great safety. In terms of antibacterial activity, terpine-4-ol can destroy bacterial cell walls, improve membrane permeability, and regulate bacterial migration, reproduction, and other related genes to inhibit bacterial activity. In terms of antifungal activity, terpine-4-ol can bind with ergosterol in fungal cell walls to cause fungal death. In terms of insecticidal activity, terpine-4-ol can inhibit Na+ and K+-ATPase activity and cause the death of the insect. In terms of anticancer activity, terpine-4-ol can regulate the expression of apoptosis-related proteins in cancer cells, so as to control the apoptosis of cancer cells. In this paper, the pharmacological activity and action mechanism of terpine-4-ol were reviewed to provide a reference for further research and utilization of terpine-4-ol.
