Objective To compare the efficacies of total gastrectomy (TG) and proximal gastrectomy (PG) for patients with upper gastric cancer.Methods Databases including Medline,Cochrane Library,Web of Science,China National Knowledge Infrastructure,Wanfang database were searched to retrieve literatures on surgical treatment of upper gastric cancer which were published from January 1980 to October 2011.According to different surgical procedures,all the patients were divided into PG group and TG group.Meta analysis were performed by RevMan 5.1.Categorical variables were presented by odds ratio (OR) and 95% confidence interval (95%CI).Results Thirteen literatures including 2622 patients with upper gastric cancer were retrieved.There were 1464 patients in the TG group and 1158 patients in the PG group.There was no significant difference in the 1-year survival rate between the 2 groups (OR =1.23,P > 0.05).The 3-and 5-year survival rates of patients in the TG group were significantly higher than those of the PG group (OR =1.74,1.45,P < 0.05).There were no significant difference in the 5-year survival rates of patients in TNM Ⅰ,Ⅱ,Ⅳ stages between the 2 groups (OR =0.94,1.31,2.03,P > 0.05),while the 5-year survival rate of patients in TNM Ⅲ stage of TG group was significantly higher than PG group (OR =2.29,P < 0.05) The overall recurrence rate of TG group was slightly lower than that of PG group,with no significant difference OR =0.44,P > 0.05).The local recurrence rate of TG group was significantly lower than that of PG group (OR =0.29,P < 0.05).There was no significant difference in the distal recurrence rate between the 2 groups (OR =0.60,P > 0.05).Conclusions The medium and longterm efficacies of TG are superior than that of PG.The stage of cancer should be taken into account to determine the plan of individual treatment.

Objective To investigate the effect of β-elemene on SGC7901 gastric cancer cell line and the potential proteins involved. Methods Human SGC7901 gastric cancer cells were treated with different concentrations ofβ-elemene.Cell viability was assessed.A proteomic method,isobaric tags for relative and absolute quantitation (iTRAQ),was employed to detect the proteins altered by β-elemene.Protein expression was validated by Western blot.Results β-elemene inhibited the viability of SGC7901 gastric cancer cells in a dose-dependent manner.Altogether,147 upregulated proteins and 86 downregulated proteins were identified in response to β-elemene treatment in SGC7901 gastric cancer cell line.Among them,the expressions of p21-activated protein kinase-interacting protein 1 (PAK1IP1 ),Bcl-2-associated transcription factor 1 (BTF)and topoisomerase 2-alpha (TOPIIα)were validated by Western blot and the trends were consistent with iTRAQ results.Top pathways involved inβ-elemene treatment in SGC7901 gastric cancer cell line included ribosome signaling,peroxisome proliferator-activated receptors (PPARs)signaling pathway,regulation of actin cytoskeleton,phagosome,biosynthesis and metabolism of some amino acids.Conclusion Our results suggest a promising therapeutic role of β-elemene for gastric cancer.The differentially expressed proteins give us better insights into the potential mechanisms involved in gastric cancer treatment using β-elemene.

Chewing lice (Phthiraptera) that parasitize the globally threatened swan goose Anser cygnoides have been long recognized since the early 19th century, but those records were probably biased towards sampling of captive or domestic geese due to the small population size and limited distribution of its wild hosts. To better understand the lice species parasitizing swan geese that are endemic to East Asia, we collected chewing lice from 14 wild geese caught at 3 lakes in northeastern Mongolia. The lice were morphologically identified as 16 Trinoton anserinum (Fabricius, 1805), 11 Ornithobius domesticus Arnold, 2005, and 1 Anaticola anseris (Linnaeus, 1758). These species are known from other geese and swans, but all of them were new to the swan goose. This result also indicates no overlap in lice species between older records and our findings from wild birds. Thus, ectoparasites collected from domestic or captive animals may provide biased information on the occurrence, prevalence, host selection, and host-ectoparasite interactions from those on wild hosts.

OBJECTIVETo investigate the effects of β-elemene in suppressing the proliferation and apoptosis of SGC7901 gastric cancer cells in vitro and explore the underlying mechanisms.
METHODSUsing MTT assay, flow cytometry, and clonogenic survival assay, we assessed the effects of β-elemene on the viability, apoptosis, cell cycle distribution, and clonogenic survival of gastric cancer SGC7901 cells and gastric mucosal epithelial GES-1 cells. Western blotting was employed to determine the changes in the protein expression profiles in SGC7901 cells in response to β-elemene treatment.
RESULTSβ-elemene significantly suppressed the cell viability and increased the apoptosis of SGC7901 cells, and these effects were less obvious in GES-1 cells. β-elemene decreased clonogenic survival of SGC7901 cells, increased the proportion of G2/M phase cells, decreased the expression of Bcl-2, and increased the expression of Bax and cleaved caspase-3. β-elemene did not obviously affect the expression of total p21-activated protein kinase 1 (Pak1) but decreased the level of phospho-Pak1 (Thr423) and phospho-ERK1/2 (Thr202/Tyr204) in SGC7901 cells.
CONCLUSIONβ-elemene inhibits the proliferation and induces apoptosis of gastric cancer cells possibly by inhibiting Pak1/ERK signaling and regulating apoptosis-associated proteins such as Bcl-2 and Bax.

Objective:
To build an automatic bone age assessment system based on China 05 Bone Age Standard and the latest deep learning technology, and preliminary clinical verification was carried out.
Methods:
The left-hand radiographs of 5 000 children with suspected metabolic disorders were acquired from Wuxi Children′s Hospital. Among these cases, 2 351 patients were randomly chosen as training set, and 101 patients were randomly used as validation set. Four professional pediatric radiologists annotated the development stage according to the China 05 RUS-CHN standard with double-blind method. The mean value of the bone age assessed by experts was the reference standard which was used to train and validate the deep learning mothods based artificial intelligence (AI) model. Accuracy, mean absolute error (MAE), root mean squared error (RMSE) and time efficiency of bone age assessment were compared by using Chi-square test and
