Purpose: To explore the relationship between positive MMP-9, Cath-D and biological behaviors in gastric carcinoma( GC). Methods: Positive MMP-9 and Cath-D were detected with S-P immunohistochemical method in 128 primary tumor specimens. Results: The positive rates of MMP-9 and Cath-D in 128 cases of human GC were correlated with growth pattern, depth of invasion, TNM categories, lymph nodes metastasis(P

Objective To explore the expression of TK1 in breast carcinoma and discuss its significance of carcinogenesis and progression in breast carcinoma and its relationship with Ki67. Method Using immunohistochemistry methods of SABC and S-P to detect the expression of TK1 and Ki67 in 89 cases of breast carcinoma tissue. Results Positive rate of TK1 in the breast carcinoma was 69.7% (62/89), and the expression of TK1 was significantly associated with lymph node metastasis, TNM stage and histological grade (P < 0.05), but it was not significantly correlated with age (P > 0.05). The expression of TK1 was not significantly correlated with Ki67 in the breast carcinoma (P>0.05). Conclusions Expression of TK1 is associated with carcinogenesis and progression, and it is a poor prognostic marker of breast carcinoma. TK1 and Ki67 are the indicators of cellular growth independently.

Extensive in vitro studies reveal that multiple intracellular targets of Antrodia cinnomomea affect cell growth,apoptosis,angiogenesis,invasion and metastasis.These intracellular targets include tumor suppressor gene,cell cycle regulatory protein,transcription factor,angiogenic and metastatic factors,and apop-totic and survival regulators.In addition,Antrodia cinnomomea has immunomodulatory propertie,which plays an anti-cancer effect indirectly by means of enhancing immunity.

Objective To investigate the influence of age on perioperative clinical parameters, tumor resection effects and complications of patients with early stage gastric cancer for single lesion treated by ESD.Methods 60 patients with early stage gastric cancer for single lesion treated by ESD were chosen from January 2013 to July 2014 and divided into 2 groups including A group (35 patients) with < 60 years old and B group (25 patients) with ≥ 60 years old; and the operation time, intraoperative blood loss, hospital staying time, tumor curative resection and completed rate, the recurrence rate with follow-up and complications incidence of 2 groups were compared.Results All the patients were successfully performed the operation and no bleeding cases. There was no significant difference in the operation time, intraoperative blood loss, hospital staying time between 2 groups (P < 0.05). There was no significant difference in the tumor curative resection and completed rate between the 2 groups (P < 0.05). There was no significant difference in the recurrence rate with follow-up between 2 groups (P < 0.05). There was no signiifcant difference in the complications incidence between 2 groups (P < 0.05).Conclusion ESD is safe and feasible in the treatment of elderly patients with early stage gastric cancer for single lesion, and it is equivalent to short- and long-term efifcacy in non-elderly patients and not increase the operation time, the trauma degree and complications risk.

Objective :To explore rehabilitative effect of low—frequency (1Hz ,LF) repetitive transcranial magnetic stimulation (rTMS) combined functional electrical stimulation (FES) on lower limb spasm and motor function in pa—tients with subacute ischemic stroke (SAIS).Methods : A total of 92 SAIS patients with lower limb spasm and motor dysfunction hospitalized in our department were randomly divided into sham stimulation + FES group (sham stimu—lation group ,n=45) and low—frequency rTMS + FES group (LF—rTMS group ,n=47) ,both groups were continu—ously treated for three weeks .Lower limb motor function and spasm severity were assessed by Fugl—Meyer motor as—sessment (FMA) and modified Ashworth scale (MAS) respectively before and after treatment ,and motor evoked potential (MEP) was detected .Results : Compared with before treatment ,there was significant rise in FMA score , and significant reductions in MAS score and MEP in two groups after three—week treatment , P= 0.001 all ;com—pared with sham stimulation group ,there was significant rise in FMA score [16. 0 (13.0 ,23. 5 ) scores vs. 19. 0 (16.0 ,27.0) scores] ,and significant reductions in MAS score [1. 5 (1. 3 ,1.5) scores vs. 1. 0 (0. 5 ,1. 5) scores] and MEP [ (24.64 ± 0. 39) ms vs. (24.43 ± 0.31) ms] in LF—rTMS group after treatment , P<0.05 or < 0. 01 . Conclusion : Compared with sham stimulation + FES ,LF—rTMS + FES can more significantly improve lower limb spasm and motor function in patients with subacute ischemic stroke .

The E (envelope) protein is the smallest structural protein in all coronaviruses and is the only viral structural protein in which no variation has been detected. We conducted genome sequencing and phylogenetic analyses of SARS-CoV. Based on genome sequencing, we predicted the E protein is a transmembrane (TM) protein characterized by a TM region with strong hydrophobicity and alpha-helix conformation. We identified a segment (NH2-_L-Cys-A-Y-Cys-Cys-N_-COOH) in the carboxyl-terminal region of the E protein that appears to form three disulfide bonds with another segment of corresponding cysteines in the carboxyl-terminus of the S (spike) protein. These bonds point to a possible structural association between the E and S proteins. Our phylogenetic analyses of the E protein sequences in all published coronaviruses place SARS-CoV in an independent group in Coronaviridae and suggest a non-human animal origin.

We report a complete genomic sequence of rare isolates (minor genotype) of the SARS-CoV from SARS patients in Guangdong, China, where the first few cases emerged. The most striking discovery from the isolate is an extra 29-nucleotide sequence located at the nucleotide positions between 27,863 and 27,864 (referred to the complete sequence of BJ01) within an overlapped region composed of BGI-PUP5 (BGI-postulated uncharacterized protein 5) and BGI-PUP6 upstream of the N (nucleocapsid) protein. The discovery of this minor genotype, GD-Ins29, suggests a significant genetic event and differentiates it from the previously reported genotype, the dominant form among all sequenced SARS-CoV isolates. A 17-nt segment of this extra sequence is identical to a segment of the same size in two human mRNA sequences that may interfere with viral replication and transcription in the cytosol of the infected cells. It provides a new avenue for the exploration of the virus-host interaction in viral evolution, host pathogenesis, and vaccine development.
