Objective To investigate the influence of L‐type Helicobacter pylori(Hp‐L) infection on invasion and metastasis of gastric carcinoma .Methods Carcinoma tissues and normal tissues were collected from 80 patients with gastric cancer ,and detected for Hp‐L ,matrix metalloproteinases‐9(MMP‐9) and vascular endothelial growth factor(VEGF) by using Gram staining ,immuno‐histochemistry staining and transmission electron microscope .Results Positive rate of Hp‐L in carcinoma tissues was 67 .50% , higher than the 23 .75% of normal tissues(P<0 .05) .Positive rates of MMP‐9 and VEGF of carcinoma tissues were also higher than normal tissues(P<0 .05) .Positive rates of VEGF and MMP‐9 of carcinoma tissues positive with Hp‐L were higher than carci‐noma tissues negative with Hp‐L(P<0 .05) .The positive rate of Hp‐L in carcinoma tissues was correlated with local and distant lymph node metastasis ,and invasion depth ,but not correlated with the size of tumor .Conclusion Hp‐L infection might be correla‐ted with carcinogenesis of gastric cancer ,and could also influence metastasis and invasion of gastric cancer .

Objective To investigate the clinical value of serum VEGF levels in the diagnosis and treatment of colon cancer.Methods Serum VEGF was detected by ELISA,and CEA and CA199 concentration were detected by CLEIA in 66 patients with colon cancer,55 patients with colon benign diseases and 50 health persons.The value of individual and joint detection for VEGF in colon cancer was evaluated.Analysis had been done on relationships between serum VEGF and pathology,treatment effects and prognosis.Results The levels of serum VEGF in colon cancer group [(318.5±148.6) ng/L] were significantly higher than those in control group [(125.7±49.4) ng/L] and benign colon diseases [(136.9±52.6) ng/L] (t =8.830,8.805,all P ＜ 0.01).There was a positive correlation between serum levels of VEGF and depth of tumor size,tumor invasion,lymph node metastasis and TNM stage (P ＜ 0.01).The susceptibilities of VEGF,CEA,CA199 were 61％,45 ％,53 ％.The sensitivity of detection was improved to 86 ％ when the combined detection of VEGF,CEA and CA199 (x2 =11.237,P ＜ 0.01).The serum levels of VEGF in patients with colon cancer was significantly decreased after treatment in the 3,7,10 day compared with that before operation [(272.3±88.1),(236.8±77.4),(173.1±59.9) vs (318.5±148.6) ng/L,t=2.173,P ＜ 0.05; t =3.961,P ＜ 0.01; t=7.464,P ＜ 0.01],respectively.Conclusion The VEGF was related to the onset and progression and metastasis of colon cancer.It has clinical significancy for diagnosis of colon cancer and judgment of curative effect and prognosis.

Adverse Drug Event(ADE)is a major factor threatening patient safety.For now,the ADE detecting in China mostly relies on spontaneous reporting,a method detecting only a small proportion of ADEs,instead of reflecting the real-world clinical medication safety.Global Trigger Tool (GTT)is a relatively new method for detecting ADEs.This paper described the GTT as an effective and practical method for detecting ADEs,by introducing the history of GTT development,GTT basic principles,operating procedures,current relevant researches and application at home and aboard and comparing with other ADE detection methods.The GTT can evaluate the clinical medication safety in various medical institutions.In particular,it can target specific clinical departments or certain people to detect ADEs for obtaining more evidences of clinical medication safety.That is the reason that we recommend medical institutions at all levels learn and use GTT.

Obesity often results when regular caloric intake exceeds the energy expenditure. Hypothalamus is the center that regulates feeding and energy balance inside the body, especially the lateral hypothalamic area (LHA) and ventromedial nucleus (VMN). Acupuncture-moxibustion has achieved significant progress in treating simple obesity, and the relevant studies have revealed the central action mechanism underlying the treatment. By reviewing the literatures associated with the mechanism studies on acupuncture-moxibustion for simple obesity, this article is going to provide clinical and scientific guidance for the treatment of simple obesity with acupuncture-moxibustion.

From the TCM theoretical basis and the evidences of acupoint selection and acupuncture and moxibustion methods regarding acupuncture for post-traumatic stress disorder (PTSD), a theoretical discussion is made in this article, also a review regarding the key mechanism of experiment researches on acupuncture for PTSD is made from aspects of neurobiology and brain functional imaging, etc., which could further clarify the effect mechanism of acupuncture on PTSD. It is found that PTSD is a kind of stress syndrome accompanied with a variety of abnormal mental symptom , and acupuncture has superior effect on PTSD. Based on these, the research progress and deficiency on current mechanism study of PTSD are reviewed, hoping to offer ideas for upcoming research and to serve the clinical practice better.
