Objective] To analyze the application of the idea of Stomach Qi of Treatise on Cold-Induced Disease in the differentiation of disease and pulse. [Method] To choose and analyze the articles, line by line, related to stomach Qi, including trying to treat, diet, stool and pulse, and to conclude the application of stomach Qi thought in disease diagnosis, cure and predicting the condition of disease.[Result] Treatise on Cold-Induced Disease advocating trying drug and food, if there was fever after drug and food, it meant stomach Qi was impaired, and it was hard to cure the diseases. On the contrary, there was stomach Qi, it was easy to cure the diseases. By using Xiao Chengqi Tang to try, if there was flatus to turn, it meant that stomach Qi was strong, and Catharis could be used. On the contrary, catharis could not be used. Being able to eat meaned that there was sthenic fever in middle energizer,or stomach Qi was recovering, or middle energizer was very deficient. Being not able to eat meaned the different condition of stomach Qi, according to the accompaning symptoms. Though observing the amount, shapes, colours,smel and frequency of feces, the conditions of heat and cold, deficiency and excess of a disease could be concluded. If syndrome and pulse were consistent, it meant that Stomach Qi stil existed, and a serious il ness could be cured. conversely stomach Qi was extremely deficient, and it was hard to cure a mild il ness. Floating FuYang pulse and too creek pulse being smal er than ChongYang pulse al meaned stomach Qi existing.[Result] Treatise on Cold-Induced Disease often judged the ups and downs of stomach Qi according to the differentiation of disease and pulse ,to predict the condition of disease.

Numerous studies showed that changes in serum pepsinogen( PG)and gastrin-17( G-17)levels can reflect histological condition of gastric mucosa,that can be served as serological biopsy of gastric fundic glandular mucosa. The decrease of serum PGⅠ level and PGⅠ/ PGⅡ ratio(PGR)as well as increase of G-17 denotes a high risk of gastric cancer. Helicobacter pylori(Hp)infection can cause chronic active gastritis,and the progress of inflammation can lead to atrophy and intestinal metaplasia of mucosa. This article reviewed the diagnostic value of serum PG,G-17 and Hp antibody for atrophic gastritis and gastric cancer.

Objective To investigate the effect of HIF-2a silencing by transfection of siRNA into MG-63 cells un-der hypoxia. Methods HIF-2αexpression level in MG-63 cells under hypoxia was determined by Western Blot. Small in-terfering RNA (siRNA) was used to construct MG-63/siHIF-2α(siHIF-2α)cells and control MG-63/scramble (NC) cells. The expression levels of HIF-2α, Vascular endothelial growth factor (VEGF), p-Erk/ErK and Mcl-1 in MG-63, NC and si-HIF-2αcells was determined by Western Blot. NC and siHIF-2αcells were cultured under hypoxia. Cell viability was as-sessed by MTT assay. Migration was identified by scratch migration assay. Tumor formation was identified by clone formation assay. Nude mouse subcutaneous xenograft model was used to investigate tumor development in vivo. Results Hypoxia im-proved HIF-2αexpression in MG-63 cells in a time-dependent manner (F=2 037.412,P<0.001). HIF-2αexpression un-der hypoxia in siHIF-2αcells was lower than that in NC cells (P<0.01). Cell viability of siHIF-2αcells under hypoxia for 12 h and 24 h were lower than that in NC cells (P<0.05 or P<0.01). The relative width of scratch in siHIF-2αgroup under hypoxia for 12 h and 24 h were larger than that in NC group (P<0.01 or P<0.01). When cell counts reach 1 000-5 000, the clone formation rates of siHIF-2αcells were lower than that in NC cells (P<0.05 or P<0.01). The expression of VEGF, p-Erk/Erk and Mcl-1 protein under hypoxia in siHIF-2αcells was lower than that in NC cells(P<0.01). Tumor sizes, weights and density of siHIF-2α group in nude mice were suppressed compared with those in NC group (P<0.01). Conclusion Blocking HIF-2αsignal pathway warrants its investigation as a potential strategy in osteosarcoma treatment.

Objective To investigate the influence of health-care Qigong Baduanjin on mental health of patients with impaired glucose tolerance (IGT) . Methods Eighty-nine IGT patients were sampled from the physical examination center of Guangdong Provincial Hospital of Traditional Chinese Medicine, and then the subjects were randomly divided into groups A (N=30), B (N=29), C (N=30), which received health education, health education combined with walking exercise, health education combined with Baduanjin separately for one year. The scores of factors of physical and mental symptom checklist (SCL-90) were recorded before and after intervention. Results Compared to those before intervention, factor scores of interpersonal sensitivity and anxiety in group A were decreased obvi ously ( P<0.01) , factor scores of somatization, interpersonal sensitivity, depression, anxiety, terror, paranoia, psychosis in group B were decreased obviously (P<0.05 or P<0.01), and factor scores of somatization, inter-personal sensitivity, depression, anxiety, paranoia, psychosis in group C were also decreased obviously (P<0.05 or P<0.01) after intervention. Group B had lower factor scores of somatization and interpersonal sensitivity than group A (P<0.05), group C had lower factor scores of somatization, anxiety, and paranoia than group A (P<0.05 or P<0.01), group B had lower factor scores of anxiety than group C (P<0.05) . Conclusion Both Baduanjin and walking exercise can promote mental health of patients with IGT, and the effect of Baduanjin is superior to that of walking exercise.

Objective:To evaluate the effect of sevoflurane on necroptosis in isolated hippocampal neurons and the relationship with ryanodine receptor.Methods:Primarily cultured hippocampal neurons of fetal rats of Sprague-Dawley rats were inoculated in culture wells (100 μl/well) or culture flasks (3 ml/bottle) at a density of 5×10 5 cells/ml at 7 days of culture and divided into 3 groups ( n=24 each) using a random number table method: control group (group C), sevoflurane group (group S) and ryanodine receptor antagonist group (group R). Group C received routine culture.Ryanodine receptor antagonist Dantrolene at a final concentration of 3 μmol/L was added in group R. Thirty minutes later, the cells were placed in the incubator containing 2% sevoflurane and cultured for 5 h at 37 ℃ in S and R groups.Then cells were collected, the morphology of neurons was observed with an inverted microscope, the concentrations of free calcium ion ([Ca 2+ ] i) in cytoplasm were determined by flow cytometry, the expression of ryanodine receptor and phosphorylated MLKL protein (p-MLKL) was detected by Western blot, the expression of RIP3 was measured by immunofluorescence, and necroptosis rate was calculated. Results:Compared with group C, the [Ca 2+ ] i were significantly increased, the expression of ryanodine receptor and p-MLKL was up-regulated, and the necroptosis rate was increased in S and R groups ( P<0.05). Compared with group S, the expression of ryanodine receptor and p-MLKL was significantly down-regulated, and the [Ca 2+ ] i and necroptosis rate were decreased in group R ( P<0.05). There was no obvious abnormality in the morphology of neurons in group C. The cell body of neurons were shrunk, the processes were broken, and the network between processes was sparse in group S. The cell body was round, and the morphology was close to normal in group R. Conclusion:Sevoflurane can cause necroptosis in isolated hippocampal neurons of rats, and the mechanism is related to up-regulating the expression of ryanodine receptors and leading to calcium overload.

Objective To investigate the correlation of K-ras gene mutations and activation of Hedgehog signaling pathway in pancreatic cancer cell lines.Methods Real-time PCR was used to detect K-ras gene mutations at codon 12 and 13 in pancreatic cancer cell lines of SW1990,PaTu8988,CFPAC-1,PANC1,AsPC-1,Capanc-2,BxPC-3 and the mRNA expression of Glil,Smo in these cell lines.Results The K-ras mutation of PANC1,CFPAC-1,AsPC-1,PaTu8988 was at codon 12,while SW1990 was at codon 13,BxPC-3,Capanc-2 were wild type.The expressions of Glil mRNA of AsPC-1,CFPAC-1,PANC1,PaTu8988,SW1990,BxPC-3,Capanc-2 were 7.84 ± 8.92,1.82 ± 3.45,1.00± 0.00,0.07 ± 0.10,0.88 ± 1.48,0.52 ± 0.98,0.15 ± 0.19,and the expressions of Smo mRNA were 144.00 ± 58.33,3.48 ±3.77,1.00 ±0.00,81.68 ±28.26,0.72 ±0.87,0.34 ±0.60,0.02 ±0.03.Glil,Smo mRNA expressions of cells with wild tpye K-ras were significantly lower than those with mutant type,and wild type BxPC-3's Glil,Smo mRNA expressions were significantly lower than that of mutant AxPC-1 (P ＜ 0.05).Conclusions Activation of Hedgehog signaling pathway may be related to K-ras gene mutations.
