OBJECTIVETo systematically evaluate the effectiveness of integrative medicine (IM) for preventing postoperative recurrence of primary hepatic carcinomas (PHC).
METHODSSuch databases as The Cochrane Library, PubMed, EMbase, China National Knowledge Infrastructure (CNKI), VIP Database, Wan-fang Database were retrieved to collect randomized controlled trials (RCTs) on preventing postoperative recurrence of PHC by IM. The retrieval period started from database establishment to June 2013. Literature screening, data extraction, and quality evaluation were performed by two reviewers strictly according to inclusion criteria. Meta-analysis was conducted using RevMan 5.2 Software.
RESULTSA total of 5 RCTs involving 367 patient cases were included. Results of Meta-analysis showed that the IM group was superior to the Western medicine (WM) group in the 1-, 2-, and 3-year recurrence rates (P < 0.05).
CONCLUSIONIn the prevention of postoperative recurrence of PHC, the effectiveness of IM was more significant, when compared with treatment of Western medicine.

BACKGROUND: At present, finite element analysis can be used to judge intertrochanteric fractures, but mostly limited in the distribution of stress. Finite element model of various intertrochanteric fractures has not been reported in detail.OBJECTIVE: To build various types of intertrochanteric fracture models with Hypermesh 14.0 and LS-DYNA software to simulate the falling-induced external force on proximal femur, and to evaluate the effect of models, and to analyze the biomechanical mechanism of intertrochanteric fractures. METHODS: Normal side CT image data of one case of elderly intertrochanteric fracture were collected and imported into Mimics software to establish the proximal femur geometric models, were then analyzed and operated by LZ-DYNA solver after imported into Geomagic studio 2013 and Hypermesh 14.0 for smoothing and meshing. Before analysis, the material parameters were set, the boundary conditions were confirmed, and given the loading parameters. The operating results were checked in Hyper View. RESULTS AND CONCLUSION: (1) The distribution of stress of proximal femur exactly matched to the previous study. EvansⅠtype intertrochanteric fracture model was obtained under continuous shear stresses, and six types of fractures were obtained by adjusting the load. (2) These results manifest that based on the Hypermesh 14.0 and LS-DYNA software, the finite element can well simulate the intertrochanteric fractures, and shear stress plays an important role in intertrochanteric fractures, which can provide experimental basis for the prevention and treatment of intertrochanteric fractures.

In recent years, more and more research shows that the pharmacokinetic parameter of traditional Chinese medicine can be affected by the disease states. It's possible that drug metabolic enzymes, transporters, cell membrane permeability and the change of microbes group could be interfered with physiological and pathological changes, which enables the pharmacokinetics of traditional Chinese medicine in the body to be altered, including the process of absorption, distribution, metabolism and excretion, and then the pharmacokinetic parameters of traditional chinese medicine are altered. It's found that investigating the pharmacokinetic of traditional Chinese medicine in the pathological state is more useful than that of in normal state because the great part of traditional Chinese medicine is mainly used to treat disease. This article reflects the latest research on the pharmacokinetic of traditional Chinese medicine in the disease state such as diabete, cerebral ischemia, liver injury, inflammatory disease, nervous system disorders and fever in order to provide certain reference for clinicians designing reasonable administration dose.

In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.

7. Effect of transforming growth factor β signaling on the stem cell-mediated liver regeneration in mice after partial hepatectomy
Journal of Shanghai Jiaotong University(Medical Science) 2019;39(3):258-263
Objective • To explore the effect of inhibiting transforming growth factor β (TGF-β) signaling pathway on the stem cell-mediated liver regeneration in mice after partial hepatectomy (PH). Methods • Eighteen C57BL/6 male mice were selected to establish the model of hepatectomy. mRNA and protein levels of the signal molecules in TGF-β pathway, as well as stem cell markers α-fetoprotein (AFP) and leucine-rich repeat-containing G-protein coupled receptor 5 (LGR5) in the liver tissues were detected before (PH0) and on the 1st (PH1), 3rd (PH3) and 7th (PH7) day after operation. Then, additional 32 mice were assigned into inhibitor group [PH+SB-431542, 10 mg/(kg•d)] and control group (PH+normal saline). The mice were sacrificed on the 1st (PH1) and 3rd (PH3) day after operation and liver remnants were obtained. Realtime-PCR, Western blotting, and immunofluorescence staining were used to detect the expressing variation of TGF-β signaling pathway, AFP and LGR5. Results • The mRNA and protein expression of TGF-β1, phosphorylated SMAD2 (p-SMAD2) protein, Afp mRNA, the number of AFP immune-positive cells and Lgr5 mRNA were upregulated significantly after PH, peaked at PH3 (P<0.05) and recovered to pre-operative level at PH7. Compared with control group, the above indices were all obviously inhibited in inhibitor group at PH3 (P<0.05). Conclusion • TGF-β signaling pathway may regulate the stem cell-mediated liver regeneration in mice after PH.
