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: With good biocompatibility, osteoconduction and biodegradability, calcium phosphate ceramics is considered as a substitute of autologous bone; furthermore, it also has the potentiel of osteoinduction after structure optimization. OBJECTIVE: To review the physicochemical properties of calcium phosphate ceramic and its osteoinduction. METHODS: A computer-based search of databases such as PubMed, Springer, ResearchGate and Baidu Academic was performed for articles relevant to calcium phosphate ceramics published from January 2000 to October 2015. And the keywords were “calcium phosphate, osteoinduction, tissue engineering, scaffolds” in English. RESULTS AND CONCLUSION: To date, there are four ideal kinds of calcium phosphate materials including hydroxyapatite, tricalcium phosphate, amorphous calcium phosphate and hydroxyapatite/tricalcium phosphate biphasic ceramic material. Hydroxyapatite has better strength and cel adsorption capacity, but has poor biodegradation. Tricalcium phosphate has good abilities of osteogenesis and degradation, but its degradation rate is hard to match the new bone formation,and its strength is also relatively poor. Amorphous calcium phosphate has neither strength nor solubility. In contrast, biphasic calcium phosphate ceramics has moderate degradation rate between hydroxyapatite and tricalcium phosphate, and therefore, it either can be replaced by autologous bone after degradation or exhibits proper strength. While how to further improve the physical properties and promote osteogenesis stil need much deeper research.

Objective To establish hyperoxia retinopathy in premature rat model with SpragueDawley (SD),observe the pathological changes of angiogenesis and expression of vascular endothelial growth factor (VEGF),and compare the effect of bevacizumab periocular injection and intravitreal injection of retinopathy of premature rats.Methods Ninety preterm rat retinopathy models were randomly divided into 3 groups:high oxygen group,retrobalbar injection group,and vitreous cavity group (n =30 per group);36 healthy rats were chosen as the normal control group.Each group were randomly selected 10 rats 'right eyes to make retinal flat mount to observe the right eye retina vascular morphology;10 resections of right eyes were embedded in paraffin,and stained with hematoxylin eosin (HE);the number of right eye of retinal neovascularization was observed;the right eye RNA was extracted,and reverse-transcription polymerase chain reaction (RT-PCR) was used to detect the expression of VEGF.Results The normal group showed retinal vessels were around a reflection of distribution,good branch,shape rules,and clear structure.Intravitreous neovascularization occurred in the high oxygen group and peribulbar injection group.Retinal vascular endothelial cells in the high oxygen group were increased significantly compared to the normal group (P ＜ 0.05).The visible clusters of red blood cells in the periocular injection group and vitreous group were decreased compared to the high oxygen group (P ＜ 0.05),but no significant difference between the periocular injection group and vitreous group (P ＞ 0.05).The expressions of VEGF mRNA and HE staining had a consistent trend.Conclusions Bevacizumab inhibited the expression of VEGF that was increased in premature rats in hyperoxia retinopathy.The effects of bevacizumab periocular injection and intravitreal injection were similar,but the former was more secure than the latter.

BACKGROUND:Posterior lumbar interbody fusion can thoroughly decompress the central canal, which is the common surgical technique for the central type of lumbar disc herniation with intervertebral instability at low lumbar segment. However, due to the regular traction on dural sac and nerve root in the operation, lower limb radicular pain in the early stage is inevitable. OBJECTIVE:To evaluate the effect of local use of gelatin sponge containing prednisolone acetate around the nerve roots after posterior lumbar interbody fusion on lower limb radicular pain. METHED:Sixty-three cases of lumbar disc herniation with degenerative instability were devided into treatment group (n=21) and control group (n=42) based on the type of implants. Gelatin sponge containing prednisolone acetate was implanted into patients in the treatment group after posterior lumbar interbody fusion, while pure gelatin sponge was implanted into patients in the control group. RESULTS AND CONCLUSION:Compared with the control group, radicular pain in the treatment group was significantly relieved within 1 week after surgery. The visual analog scale score and Oswestry disability index score were similar between the two groups. There were three cases of radicular pain recurrence in the control group, but no incision infection and epidural hematoma after surgery in both two groups. In conclusion, local use of gelatin sponge containing prednisolone acetate around the nerve roots can significantly relieve lower limb radicular pain in the early stage after posterior lumbar interbody fusion in lumbar disc herniation, contributing to early rehabilitation exercise and patient satisfaction outcomes.

Objective:To study the effect of interleukin-18 on transdifferentiation in renal tubular epithelial cells(TECs).Methods:Human proximal tubular epithelial cell line(HK-2) was cultured in vitro.TECs were exposed to different concentrations(0,0.1,1,10 and 100 ng/ml) of IL-18 for 24,48 and 72 hours.At the end of each incubation,the expressions of the ?-SMA and TGF-?_1 mRNA were assessed by RT-PCR,the rate of ?-SMA expressing TECs was assessed by immunocytochemistry,and the expression of the ?-SMA protein was assessed by Western blotting.Results:(1)The expressions of ?-SMA and TGF-?_1 mRNA were increased significantly by a dose- and time-dependent manner when TECs were exposed to IL-18(P

Objective To study the roles of regulated upon activation normal T cell expressed and secreted(RANTES) and monocyte cbemoattractant protein-1 (MCP-1) in human immunodeficien- cy virus-1(HIV 1) infected patients.Methods RANTES and MCP-1 in HIV-1 infected patients, including treated and untreated groups,and healthy control group were determined by enzyme-linked immunosorbent assay(ELISA).The recombinant plasmids,hMCP-pcDNA3.1,bRANTES- peDNA3.1 and hMCP/bRANTES-pcDNA3.1,were constructed and transfected into CHO cells to overexpress the corresponding recombinant proteins,whose chemoattract function was then studied. Results The level of RANTES was (164.3?21.3) pg/mL in healthy control group,(1 224.1?62.0) pg/mL in untreated group and (475.3?36.2) pg/mL in treated group.The level of MCP-1 was (90.6?28.5) pg/mL in healthy control group,(335.0?30.3) pg/mL in untreated group and (807.2?62.6) pg/mL in treated group.In HIV-1 infected patients,the levels of RANTES and MCP-1 were significantly increased.After highly active antiretroviral therapy (HAART),the level of RANTES declined,but MCP-1 increased further.Western blot assay revealed that the three recombinant proteins could be recognized by monoclonal antibodies respectively.All of them could chemoattract human peripheral blood mononuclear cells(PBMCs).And the chemoattractant potency of MCP/RANTES fusion protein was stronger.When the recombinant proteins were used with con- centrations as 50,200,400 and 800 pg/mL,respectively,the number of PBMCs chemoattracted by MCP/RANTES fusion protein was 52?10~4/mL,102?10~4/mL,132?10~4/mL and 184?10~4/mL; the number of PBMCs chemoattracted by RANTES was 27?10~4/mL,51?10~4/mL,65?10~4/mL and 96?10~4/mL;the number of PBMCs chemoattracted by MCP-1 was 18?10~4/mL,44?10~4/mL, 54?10~4/mL and 74?10~4/mL.Conclusion RANTES and MCP-1 may both be involved in the HIV infection process and host immunological reaction against HIV.

In this study, a novel tetrapeptide hydrophilic interaction chromatography (HILIC) material was synthesized, and corresponding enrichment method for glycopeptides was developed.The tetrapeptide modified silica gel materials (denoted as Poly-DAPD) were synthesized by atom-transfer radical-polymerization (ATRP) and characterized by N2 adsorption desorption and thermometer, thermal gravimetric analyzer (TGA) and X-ray photoelectron spectrometer (XPS).The characterization results indicated that tetrapeptide had been successfully synthesized on silica gel.Poly-DAPD materials showed high enrichment selectivity toward fetuin glycopeptides under solid-phase extraction (SPE) mode.Comparing with commercialized ZIC-HILIC in glycopeptides enrichment of fetuin digest which mixed with 5 mole ratio of albumin bovine (BSA), the as-prepared materials showed higher selectivity in both aspects of the identified number of glycopeptides and anti-interference property.The SPE results demonstrated that the tetrapeptide-based HILIC materials could be a potential tool in large-scale glycosylation analysis.
