There are some limits and irrationality in practical application of the clause 3.1, 3.2, 4.4.2, 4.5.2, 4.9.1 of YY 0672.1-2008 as the industry standard for laparoscopic trocar. This paper puts forward some opinion and advice.

Micrometastasis of carcinoma is one of the most significant pieces of evidence for molecular staging.Detection of micrometastasis of non-small-cell lung cancer plays a significant role in staging precisely,guiding treatment and predicting the prognosis of patients.This review is focused on the latest developments of markers such as CK19,LUNX,CEA mRNA,oncogene and anti-oncogene.The sites about micrometastasis of non-small-cell lung cancer are usually reported in lymph node and bone marrow,rarely in pleural cavity and increasingly in peripheral blood.

The results of electrocardiogram and coronary angiography were compared in 69 patients with acute inferior myocardial infarction(right ventricle, later wall). The sensitivity and specificity of ST segment elevation Ⅲ> Ⅱ in diagnosis of right coronary artery (RCA) as the infarction related artery (IRA) were 92.00% and 84. 21% respectively;those for ST segment depression avL > Ⅰ were 90. 00% and 89. 5% respectively. Therefore if ST-elevation Ⅲ > Ⅱ , ST-depression avL > Ⅰ and no depression on STV1 and V2 in acute inferior myocardial infarction may highly indicate that RAC be the IRA;on the contrary, the LCX be the IRA.

Leptin promotes proliferation of cancer cells via various signal transduction pathways and contributes to angiogenesis in gastric cancer. Leptin expression level is significantly higher in gastric cancer than in normal gastric mucous tissues, and correlates with clinicopathological features such as differentiation,tumor size and distant metastasis. Leptin has become a prognostic factor and a new therapy target of gastric cancer.

Objective To investigate the effect of Er:YAG laser irradiation on the structure of dental hard tissue.Methods 2 teeth (8 samples) were randomly selected from 26 teeth enamel group(104 samples) for blank control(group C).The remaining 24 teeth (96 samples) were randomly divided into A group (irradiation 10 s) and B group (20 s irradiation),each group according to power were randomly divided into 1,2,3,4,5,6 W six subgroups,each subgroup had 8 samples.Using a Er:YAG laser at 20 Hz frequency,according to the corresponding packet (with different power and different irradiation time) were irradiated for each sample.Dentin grouped with enamel group.To observe the changes of different energy and the pit diameter and depth.Results The enamel surface pit diameter was compared by different irradiation time and power,different power within the same irradiation time (t =1.89,2.02,2.76,1.98,1.37,1.42,all P ＜ 0 05) ; compared between B group and the A group under the same power (t =1.23,3.23,2.04,1.45,1.42,1.87,all P ＜ 0.05).The enamel surface pit depth was compared by different irradiation time and power,different power within the same irradiation time (t =1.15,3.09,2.32,1.76,1.51,1.59,all P ＜ 0.05) ;compared between B group and the A group under the same power (t =1.15,3.09,2.32,1.76,1.51,1.59,all P ＜0.05).The dentin surface pit diameter was compared by different irradiation time and power,different power within the same irradiation time (t =1.15,3.09,2.32,1.76,1.51,1.59,all P ＜ 0.05) ; compared between B group and the A group under the same power(t =1.15,3.09,2.32,1.76,1.51,1.59,all P ＜ 0.05).The dentin surface pit depth was compared by different irradiation time and power,diffe rent power within the same irradiation time (t =2.12,2.04,1.82,1.43,1.31,1.76,all P ＜ 0.05) ; compared between B group and the A group under the same power(t =2.34,3.13,2.76,1.45,1.34,1.62,all P＜0.05).Conclusion With the increase in the laser energy and the irradiation time,the diameter and depth of enamel pits produced also continuously increase;With the increase in the laser energy and the irradiation time,dentin diameter and depth of the pits produced constantly increased.The different parameters of Er:YAG laser irradiation of dental hard tissues have different effects on the structure.
