Objective To evaluate the effect of esophagogastric intramural implantation anastomosis after esophagectomy. Methods One thousand and two hundred thirty-six patients with esophageal and cardial cancers were treated by esophagogastric intramural implantation anastomosis after esophagectomy. The mucosal layer, the esophageal and gastric muscular layers were on three different levels after the anastomosis. Results Among 1236 patients, 842 cases were esophageal cancer,and 394 cases were cardial cancer.The anastomoses were performed in different levels including 15 cases below the pharynx, 193 cases on neck,634 case above the aortic arch and 394 cases below the aortic arch. One of the patients died 24 hours after the operation due to myocardial ischemia, and two of them died of respiratory failure. Anastomotic leakage, stenosis and refluxing esophagitis did not appear in this series. Conclusions Esophagogastric intramural implantation anastomosis can decrease the incidence of anastomotic leakage, stenosis and refluxing esophagitis after esophagectomy.

Objective To evaluate the efficacy of different duration of low-carbohydrate diet (LCD) intervention on glycosylated hemoglobin (HbA1c) in type 2 diabetes mellitus (T2DM) patients. Methods Randomized controlled trials (RCTs) of LCD intervention in T2DM patients were collected in the databases such as MEDLINE, PubMed, OVID, China National Knowledge Infrastructure, China Scientific Journal Database by VIP, Wanfang database, et al.Data were analyzed by RevMan 5.3 version. Results Eight RCTs were included. The results of Meta-analysis indicated that the effects of lowering HbA1c by LCD intervention for three (Z=2.28, P<0.05) and six months (Z=14.99, P<0.01) were better than other diabetes diets, but there was no significant statistical difference between one (Z=0.65, P=0.51) and two years (Z=1.62, P=0.10). Conclusions Hypoglycemic effect of short-term LCD was better than other diabetes diets, but long-term effect was similar between them. LCD was a therapeutic diet suitable for T2DM patients.

Objective To explore the inhibition effects of epidermal growth factor receptor (EGFR) antagonist monoclonal antibody cetuximab (C225) on breast cancer stem cells in human breast cancer cell line MCF-7.Methods The effects of C225 on the proliferation of breast cancer cell line MCF-7 were detected by MTT assay. MCF-7 cells were cultured to generate primary mammospheres, and were divided into control group, C225 group, epidermal growth factor (EGF) group and EGF + C225 group according to whether or not the culture media contained exogenous EGF and C225.Thirteen days after culture, the volume and number of mammospheres of these four groups were observed, and mammosphere-forming efficiency ( MFE) was calculated. The percentages of CD44~+ CD24~- cells in mammospheres of these four groups and in routinely cultured MCF-7 cells were determined by flow cytometry. Results The inhibition rate on MCF-7 cells increased with the concentration of C225.Compared with control group, the volume of mammospheres in C225 group significantly decreased, and MFE and percentages of CD44~+ CD24~- cells in mammospheres significantly decreased [(0.61 ±0.04)% vs (1.44±0.09)%, P<0.01; (3.50±0.29)% vs (9.07 ±0.52) % , P<0.01]. Compared with EGF group, the volume of mammospheres in EGF + C225 group significantly decreased, and MFE and percentages of CD44~+ CD24~- cells in mammospheres significantly decreased [ (0.68 ± 0.04) % vs (1.61 ± 0.05) % , P < 0.01; (4.00 ± 0.58) % vs (10.47 ± 0.79) % , P < 0.01]. The percentage of CD44~+ CD24~- cells in routinely cultured MCF-7 cells was (2.03 ±0.15) % , and was significantly different from those in EGF group and control group (P < 0.01). There was no significant difference in volume of mammospheres, MFE and percentage of CD44~+ CD24~- cells in mammospheres between EGF group and control group (P >0.05). Conclusion C225 has significant inhibition effects on CD44~+ CD24~- cells in MCF cells.

Objective:To accumulate dendritic cells(DC) into the peripheral blood and induce the specific cytotoxic T lymphocyte against tumor.Methods:B220~-CD11c~+ cells were sorted from the peripheral blood of C57BL/6 mice injected i.v.with P.acnes,and cultured for about six days in the presence of GM-CSF,IL-4 and mTNF-?.Phenotype and mixed leukocyte reaction(MLR) of these cells were assayed.CTL to anti-tumor,which was developed by cultured B220~CD11c~+ cells loading tumor antigen,was detected.Results:B220~-CD11c~+ cells were rapidly accumulated in the circulation of the mice after P.acnes injection.These cells could differentiate into mature DC when cultured in the presence of cytokines for several days.Moreover,cultured B220~-CD11c~+ cells loading tumor antigen could stimulate naive splenic CD3~+T cells generate high level of IFN-? and tumor specific cytolytic reactivity in vitro.Conclusion:B220~-CD11c~+ DC precursors rapidly accumulated in the peripheral blood after injection of(P.acnes) in mice.T cells could develop specific CTL to anti-target tumor cells in vitro when stimulated with P.acnes-mobilized DC loading tumor antigen.

Objective To study the clinical effects of the combination of the topping tongue method and the scraping tongue method in speech training after the operation of ankyloglossia with lingua apical articulation disor-der.Methods Based on the random control study design,50 cases of ankyloglossia with lingua apical articulation disorders were randomly allocated into experimental group (25 cases)and control group (25cases).Patients of ex-perimental group were given routine speech training with the topping tongue and scraping tongue methods.Patients of control group were given routine speech training,and data of voice intelligibility of two groups of patients were collected at the time before speech training and after 3 courses of speech training.Results The voice intelligibility of two groups of patients before speech training had no statistically significant differences(t =0.726,P >0.05 ).But the voice intelligibility of the patients after 3 courses of speech training in both groups was obviously improved. There were statistically significant differences(P <0.001).Patients in the experimental group had a higher voice in-telligibility score assessed after 3 courses of speech training than the control group.After treatment,the voice intel-ligibility of the patients in experimental group increased from 37.91% to 87.69%.The voice intelligibility of the pa-tients in the control group increased from 37.69% to 72.99%.There were statistically significant differences(P <0.001).Conclusion The combination of the topping tongue and scraping tongue methods can improve the speech intelligi-bility for patients after operation of ankyloglossia and promote rehabilitation training of the lingua- apical articulation.
