Objective\ To evaluate the immediate effects and strength of allograft fusion cage(AFC) used for reconstructing stability of cervical spine. Methods\ Discs of C 5 and C 6 were resected on 8 fresh human cervical spine specimens, and autogenous iliac bone grafts(AIBG), and AFCs were implanted into the intervertebral spaces respectively. Compression test, pull out test and segmental motion measurement were studied.Results\ Comparing with intact and AIBG groups, the range of motions of C5-6 in AFC group were decreased in all directions except for extension; with (502?114) N compressive load,the vertebrae in AFC group were broken while the AFC were intact, but the AIBG were broken at (135?42) N load; with 300 N drawing load,no loosening was found between AFCs and vertebra, but it was found between AIBG and vertebra at 60 N load. Conclusion\ AFC could provide enough support,anti slide ability and could remain or increase the height of intervertebral spaces. It completely meets clinical and biomechanical requirements.

Methods: The expressions of hTERT gene were detected by immunocytochemistry staining in 54 patients with transitional cell carcinoma(25 cases with grade Ⅰ, 26 with grade Ⅱ and 13 with grade Ⅲ) and 20 controls, including 10 patients with urinary tract stone and 10 healthy volunteers. The urine exfoliative cells of both groups were also stained by H-E and the results were compared with those of immunocytochemistry.Results: hTERT was detected in 74.1% (40/54) of patients with transitional cell carcinoma and in 5%(1/20) of the controls (P

Objective To observe the ultrasonographic features of local chest wall tumor recurrence after mastectomy for breast cancer and its clinical and histopathological characteristics. Methods The ultrasonographic features, clinical and histopathological characteristics of 27 patients with local chest wall tumor recurrence after mastectomy confirmed histopathologically were retrospectively reviewed. Results The disease-free intervals of twenty-seven patients ranged from 3 to 129 months [mean (31.9±31.4) months]. Most of the recurrence(18/27, 66.7%) occurred within 3 years after mastectomy. The clinical manifestations were:7 cases (7/27, 25.9%) with regional skin redness and swelling, red rash or ulceration on chest wall associated with or without palpable mass, 20 cases(20/27, 74.1%) with chest wall palpable masses without obvious skin change. On ultrasonography, 2 cases showed diffuse inifltrative type with ill-deifned inhomogeneous hypoechoic lesion and skin thickening. And twenty-ifve cases(43 lesions) showed mass type with a lesion size range of 5.4-114.7 mm [mean (24.4±21.6) mm]. Among them, 32 lesions were located near to the operation incision scar, 36 involved muscle layer, 38 were hypoechoic, 31 had irregular shape, 24 had indistinct margin, and 31 had blood lfow signal. In addition, calciifcation, halo, and taller-than-wide shape were absent in all 43 lesions. Conclusions The tumor recurrence often occurred within 3 years after mastectomy in high-risk patients. Ultrasonographic feature of chest wall recurrent lesion is of great value in the diagnosis.

A new compound and twelve known compounds were isolated from the ethyl acetate extract of the roots of Homonoia riparia Lour, which are used in folk medicine for treatment of hepatitis, bellyache and scald, by the method of silica gel column chromatography repeatedly with a gradient of PE-EtOAc, PE-Me2CO, CHCl3-Me2CO, CHCl3-MeOH. Their structures were identified as a new compound 1-oxo-aleuritolic acid (1), and twelve known compounds aleuritolic acid (2), 3-acetoxy-aleuritolic acid (3), taraxerone (4), taraxerol (5), methyl 3-acetoxy-12-oleanen-28-oate (6), 3-acetoxy-12-oleanen-28-ol (7), ursolic acid (8), lupenol (9), 3β-acetoxy-lupenol (10), cleomiscosin A (11), chrysophanol (12), and gallic acid (13), which were obtained from this plant for the first time, by the spectroscopic techniques of NMR, HMBC, IR and MS, separately. Among the cytotoxicities evaluation of compounds 1-3 towards AGZY 83-a (human lung cancer cells) and SMMC-7721 (human liver cancer cells) tumor cells was assayed by MTT methods with cis-dichlorodiamminoplatinum (DDP) used as positive control. Compound 2 exerted weak activity against AGZY 83-a with the IC50 value of 33.055 μg·mL-1, while 1 and 3 showed no activity to these two cell lines.

Objective To investigate the effect of hypoxia-inducible factor-1α expression (HIF-1α) on toll-like receptor 4 (TLR4) signaling pathway-mediated rat lung ischemia-reperfusion injury (LIRI).Method Forty-five S-D rats were randomly divided into Sham group,LIRI group,LIRI+ TLR4-activated group,LIRI+ TLR4-inhibited group,LIRI + ASK1-inhibited group,LIRI + p38-inhibited group,and LIRI + HIF-1α-inhibited group.The interaction between TLR4 signaling pathway [including TLR4,myeloid differentiation factor 88 (MyD88),TIR-domain-containing adapter-inducing interferon-βTIR-domain-containing adapter-inducing interferon-β (TRIF),Apoptosis signal-regulating kinase 1 (ASK1) and p38] and HIF-1α and the role of TLR4-dependent HIF-1α in LIRI in vivo were analyzed.Result In LIRI,HIF-1α accumulation was induced in a TLR4-dependent fashion,and MyD88,but not TRIF,and activation of ASK1 and P38 were found to be critical for TLR4-mediated HIF-1α accumulation.HIF-1α protein played a critical role in TLR4-mediated lung injury of LIRI.HIF-1α up-regulated TLR4 expression in LIRI in a positive feedback manner.Conclusion We identify that HIF-1α has a damaging effect on TLR4 signaling pathway-mediated LIRI and TLR4-HIF-1 may synergistically involved in the development of LIRI.Therefore we suggest that the interaction between them may represent a novel therapeutic target for the development of novel target-based therapies of LIRI.

Objective: To observe the effect of elk antlers ethanolic fluidextract on behavior and immune function of aging model mice. Methods: ICR mice were randomly divided into 4 groups: Normal control group (NG), model control group (MG), low-dose drug treatment group (LG,2g/kg) and high-dose drug treatment group (HG,4g/kg). Mice were given subcutaneous injection of D-galactose (D-gal) at 120 mg/kg to induce subacute aging model. At the same time LG and HG were respectively administrated corresponding concentration of elk antlers ethanolic extract. Six weeks later, the learning and memory test was run by Y-maze. Then single agar immunodiffusion method was used to detect IgG level in serum, and spleen lymphocyte transforming stimulation index (SI) was determined by methyl thiazolyl tetrazolium(MTT) method as well as the concentration of Interleukin-2(IL-2) and interferon-gama(IFN-?) in serum were determined by ELISA method. Results: The memory and immune function of aging mice declined signif icantly. Elk antlers ethanolic fluidextract could obviously improve memory ability, increase the IgG level, raise the lymphocyte transforming SI, and elevate the concentration of IL-2 and IFN-? in model mice induced by D-gal. Conclusions: Elk antlers ethanolic extract could improve behavior and immune function of aging mice to delay aging process.

Objective To analyze the significance of the liquid-based thinprep cytologic test (TCT ) in early cervical cancer screening by comparing cervical atypical squamous cells (ASC) and the histologic diagnostic results in order to guide the clinician to correctly understand the meaning of ASC and further explore the effective method of early cervical cancer screening .Methods 163 cases of cervical ASC diagnosed by histology and TCT were retrospectively analyzed and the comparative analysis was performed . Results Among 163 cases of cervical biopsy ,50 cases were ASC of undetermined significance (ASC-US) diagnosed by TCT ,the positive cases verified by the histology accounted for 49 .3% ;13 cases were ASC of highly squamous intraepithelial lesions diag-nosed by TCT ,the positive cases verified by the histology accounted for 76 .9% .The cases of ASC-US diagnosed by cytology and cervical intraepithelial neoplasia grade Ⅱ(CIN Ⅱ) and above diagnosed by histology accounted for 12% .Conclusion ASC-H high-ly suggests the clinical possibility of high-grade intraepithelial neoplasia .ASC-US is a suggestive diagnosis rather than a clarity di-agnosis .Correctly understanding the clinical significance of ASC can discover early cervical lesions as early as possible .
