Apoptosis induced byP53 gene is one of the most important mechanisms of signal integration in cells,which identify the cell injury and start downstream apoptotic signals.PIG7 gene is induced byP53 and correlates with metabolism,inflammation and tumor occurence.Here we reviewed the recent findings in the molecular biology ofPIG7 gene and the correlation with human diseases.

FLT3, a tyrosine kinase receptor, is the most common mutation in AML and has two classes of mutations: internal tandem duplications in the juxtamembrane domain (FLT3-ITDs) and point mutations in the tyrosine kinase domain (FLT3-TKDs). AML patients with FLT3 mutations tend to have a poor prognosis. As an independent factor, the presences of FLT3 mutations play an important role in the origin and development of AML and have prognostic value. Molecular targeted therapy represents a novel and popular therapeutic approach in the world. In this review, we explain clinical value of the FLT3 mutations, mechanism and research progression of the FLT3 inhibitor;and discuss difficulties and perspectives in the research of the FLT3 inhibitor.

Objective: To establish the quality standard for Shenqinaoqing Granule(Radix Astragali, Radix Ginseng, Radix Angelicae Sinensis, Radix Polygoni Multiflori, etc.) Methods: Astragaloside I of Shenqinaoqing Granule was determined by TLC-scanning, Rhizome Astragali, Radix Ginseng, Radix Polygoni Multiflori, Radix Paeoniae alba were identified by TLC. Results: TLC spot developed were fairly clear, and the blank test showed no interference. Astragaloside I showed a good linear relationship in the concentration range of 0.50～5.05?g and the average recovery was up to 97.10%, RSD was 1.34%. Conclusion: The methods can be effecive for the quality control of the Shenqinaoqin Capsule.

West syndrome is one of the most common refractory epileptic syndromes with onsets mostly in infancy.The prognosis is generally poor.The morbidity rate reported in the literature is 0.2‰ to 0.5‰.Hormonal therapies(Adrenocorticotropic hormone and glucocorticosteroid)are recommended as preferred treatment options for West syndrome.It can effectively control spasms, ameliorate recognition impairment, and improve developmental outcomes.The incidence of side effects after hormonal therapy are high, and irritation, hypertension and infection are frequently reported.In this paper, advances in therapeutic mechanism, usage and dosage, short-term effectiveness, long-term effectiveness, prognosis and adverse effects of hormonal therapies are reviewed.

Objective To analyze the influence of ionizing radiation on the viability of the regulatory T cells and the relationship between the expression of CD39 and apoptosis related factors in mice Treg cells.Methods Mice were administered to whole body irradiation with 2 Gy of γ-rays,then lymphocytes were separated from thymus and spleen.The percentages of CD4 + T and CD4 + FOXP3 +CD25 + Treg lymphocytes,apoptosis related genes of Bax,Bcl-2 and CD39 were analyzed with FACS.Results Treg cells had a higher survival fraction than CD4 + FOXP3-Tcon cells after irradiation,and the time-responses of Treg cells in thymus and spleen were different.The apoptosis rate of Treg cells increased at 4 d after irradiation(t =-3.6,-7.4,P ＜0.05).The Bax/Bcl-2 ratio and the CD39 expression were increased in thymus Treg cells (t =-3.4,-6.6,P ＜ 0.05),but decreased in spleen Treg cells (t =2.4,2.6,P ＜0.05).Conclusions Thechanges of apoptosis and Bax/Bcl-2 are in consistent with the expression of CD39 in the irradiated Treg cells.

Objective Zinc sulfate has anti inflammatory action in many animal models, however, the effects of zinc in colitis remained uncertain. The present study was to evaluate the role of zinc sulfate in experimental colitis and probe into its underlying mechanisms. Methods Colitis was induced by administrating 2,4,6 trinitrobenzenesulphonic acid (TNB) rectally in Spragur Dawley female rats. Beginning at the first day of TNB colitis, the rats were treated with zinc sulfate enema once daily for 6 days. The rats were sacrificed at days 8. The effects of zinc sulfate were evaluated by examining mucosal lesion area, mucosal myeloperoxidase (MPO) and superoxide dismutase (SOD) activities, mucosal prostaglandin E 2(PGE 2) and leukotriene B 4(LTB 4) levels. Results TNB induced severe colitis as evidenced by increased mucosal lesion area, mucosal MPO activity and PGE 2 and LTB 4 levels. Six days after the application of the zinc sulfate enema, the mucosal lesion area, MPO activity, PGE 2 and LTB 4 levels were all decreased significantly, except mucosal SOD activity that was remained unchanged after zinc treatments. Conclusions The data suggest that zinc sulfate enemas have an anti inflammatory action on experimental colitis through the mechanism other than increasing SOD activity.

Objective To investigate the methods and efficacy of coronary stent placement in patients with myocardial bridge. Methods 4 patients with angina and ST-T changes in ECG were involved in the study. Coronary angiography showed there were 75%～90% systolic stenosis of LAD in all patients. Two of them were regarded as isolated myocardial bridge, and the others were regarded as myocardial bridge associated with atherosclerosis. The length of artery pressed by myocardial bridge was in the range of 10～18 mm. All patients who had repeated angina accepted stenting therapy. One of the stents was Crossflex, three were Nir stents. Stents size: (3.0～3.5)?(12～20)mm. All stents were expanded with 8～10 atm for 30～40 seconds. Results After stenting, coronary angiography showed no residual stenosis. In the follow-up 6～18 months there were no complaints of angina. In two of them, coronary angiography showed there were no restenosis after one year.Conclusion Coronary stenting is an optional method to treat patient who have myocardial bridge and have no efficacy after taking medicines, especially for the patients who have both myocardial bridge and atherosclersis. But futher study in large populations is still necessary.

ve To improve the method of determination of aluminium in water. Methods The method of aluminium chrome azurol S-cetylpyridinium bromide spectrophotometry was used. Results The improved determi-nation of aluminium revealed perfect linear relationship in determining the standard aluminium solution series at the range of 0. 0-6.0?g/25 ml aluminium. The regression equation was calculated as y = 1. 031x + 0. 008(r=0.9994) . The detection limit was 0.02 mg/L aluminium. The coefficient variation was below 4.90% . The recovery rate ranged from 93.3% to 100.0% . Conclusion The improved method was rapid and easy to operate, suitable for determination of Al3+ in a large number of water samples.

Objective To analyze the differences of nutritional parameters and body composition in the protein energy wasting (PEW) patients on maintenance hemodialysis with or without diabetic kidney disease (DKD).Methods The patients with PEW were screened by subjective global assessment (SGA) from patients on maintenance hemodialysis from March 2014 to June 2015 in the Fourth Central Hospital of Tianjin.Anthropometric and nutritional parameters were collected before dialysis, and body composition and energy expenditure were examined by the bioelectrica] impedance method.The indexes of the two groups were compared.Results A total of 301 patients on maintenance hemodialysis (DKD 112, non-DKD 189), whose average age was (63.05±14.42) years old, were screened.Among which, 75 patients were diagnosed with PEW, and the overall prevalence rate was 24.92％, including 41 DKD cases with the prevalence of 36.61％ (41/112) and 34 non-DKD cases with the prevalence of 17.99％ (34/189).Compared with uon-PEW patients, the body mass index (BMI), hemoglobin (Hb), albumin (ALB), and total cholestero (TC) of patients with PEW were significantly lower, and C-reactive protein (CRP) were significantly higher (P＜0.05).In the DKD group, the average age of PEW onset ((59.61±13.74) years old), the maintenance dialysis time before PEW ((64± 12.50) months), ALB ((31.34±3.32) g/L), and TC ((4.17±0.95) mol/L) were all lower than those in the non-DKD group ((70.68±14.05) years old, (116.61 ±32.85) months, (32.34±4.64) g/L, (4.95±1.52) mol/L) (P＜ 0.05), respectively.The body composition results showed that muscle mass in the DKD group ((24.84±3.36) kg/ (45.32±6.95)％) was less than that of the non-DKD group ((28.53±3.75) kg/(50.67±7.28)％) (P＜0.05).Conclusions This study indicates that compared with non-DKD dialysis patients, the prevalence of PEW in dialysis patients with DKD is higher, onset age of PEW is younger, the duration of dialysis is shorter, and the muscle consumption is more obvious.
