Objective To evaluate the clinical application of VAMTS in lung cancer patients.Meth- ods Between May 2004 and June 2005,30 patients with lung cancer applied VAMTS.The minimalthoracto- my from 8 to 10 cm was made at fourth or fifth intercostal space and lobectomy was undergone for convertion- al or dedicated endoscopic instruments.Some mediastinum lymphnode(MLN)resection were performed.Re- suits Operative time from 50 to 210 minutes and average 123 minutes.The intraoperative blood loss is less, and without blood transfusion.The average drawing duct time is 3.9 days.No death caused by operation and postoperative syndromes.Conclusion VAMTS wounds much less,operative scale lumination is better,opera- tive time shorter,blood loss less,and recover more quickly.The hospitalization time is shorter.The VAMTS with MLNR is regarded as an implement of lung cancer remedy,fits to stageⅠ-Ⅱ,diameter

Objective To investigate principle and clinic pathologic characteristics of autoimmune thyroid disease(AITD) associated nephrosis. Methods By introducing 5 cases and related reference to review clinic pathologic characteristics of AITD associated nephrosis. Results AITD associated nephrosis regard proteinuria as principal, and a handful of performance is nephritic syndrome and nephritis syndrome. Pathologic characteristics are diversity. It is usually membranous nephrology, mesangial proliferative glomerulonephritis and focal and sclerosing glomerulonephritis. Conclusion Treatment of AITD associated nephrosis itself and immunosuppressive agent therapy might be useful to get remission of it.

Objective To study the effect of dimethylaminoethano (DMAE) and compound amino acid injection (AA) by mesotherapy on collagen Ⅰ and collagen Ⅲ mRNA expression levels of D-galactose-induced chemical skin aging rats.Methods 80 rats were randomly divided into individual experimental group.At 18 days after D-gal induction,rats of aging treatment groups were treated with intradermal microinjection of 0.2％ DMAE+AA,0.1％ DMAE+AA,0.2％ DMAE,0.1％ DMAE,AA,and saline,respectively,once a week for 4 weeks.At 42 days after treatment,the skin wounds were harvested.HE,PCNA,hydroxyproline and collagen Ⅰ and collagen Ⅲ mRNA expression levels of every group skins were detected.Results Dermal thickness,hydroxyproline content and collagen type Ⅰ and Ⅲ mRNA expression levels of 0.1％ DMAE+ AA and 0.2 ％ DMAE+ AA groups were significantly improved (P＜0.05),but PCNA expression of sham control group was significantly higher than all of aging groups (P＞0.05).Conclusions Local co-injection of DMAE and compound AA directly into targeted tissue under mesotherapy has marked anti-aging effects on D-galactose induced skin aging model of rat by increasing the dermal thickness,collagen content and acceleration of collagen synthesis.

Objective To study the protective effects and mechanism of aqueous extract of arctium lappa root on vas?cular endothelial cell injury in hypertensive rats. Methods The hypertensive rat model was induced by N-nitro-L-argi?nine. Rats were randomly divided into normal control group, model control group, positive control group (aptopril 15 mg/kg), low concentration of aqueous extract of arctium lappa root (0.5 g/kg), medium concentration of (1 g/kg) and high concentra?tion of (2 g/kg) groups. After six weeks of continuous intragastric administration, the systolic blood pressure levels at tail ar?tery were measured at 1, 4, 7, 10, 13, 16, 19, 22, 29, 36 and 42 d after treatment. And other indicators related to inflammato?ry factors were detected including C-reactive protein (CRP) and interleukin (IL)-6. The intercellular adhesion molecule-1 (ICAM-1) level was detected by taking samples of thoracic aorta. Results (1) The systolic blood pressure level at tail ar?tery was significantly lower in aqueous extract of arctium lappa root group than that of model control group ( P<0.05). (2) The aqueous extract of arctium lappa root can significantly improve the vascular endothelial cell injury, suppress vascular endo?thelial cell loss and blood cell adhesion, and cell proliferation with collagen fibers in muscle membrane. ( 3) The serum levels of IL-6, CRP and vascular endothelial ICAM-1 were significantly reduced in aqueous extract of arctium lappa root group than that of model control group (P<0.05). Conclusion Aqueous extract of arctium lappa root can significantly improve vascular endothelial cell injury in hypertensive rats. The mechanism may be related to the inhibition of inflammatory cyto?kines like IL-6, CRP and the expression of ICAM-1, and the improvement of chronic inflammatory response in vascular en?dothelium of hypertensive rats.

Background and purpose:This study investigated the relationship between (S100 calcium-binding protein A4, S100A4) in chronic gastritis, intestinal metaplasia, dysplasia adenomatous, normal tissue tissue samples and expression in gastric cancer and clinical characteristics. Methods:HE staining of the use of gastric specimens taken for histopathological diagnosis;using immunohistochemistry to detect the expression of tissue S100A4 protein;qRT-PCR was used to detect mRNA expression of S100A4 gene;Western Blot detection of S100A4 gene encoding protein. Kaplan-Meier survival curves were used to distinguish and compare survival. Results:S100A4 protein and mRNA expression gradually increased in the following order:normal tissue

A 56-year-old female patient of Han nationality presented with generalized erythema and vesicles for 6 days,as well as high fever for 2 days.Twenty days prior to hospitalization,the patient received surgical treatment combined with oral methazolamide and glucocorticoids for glaucoma.The patient had a history of allergy to sulfanilamides.On admission,the patient presented with generalized erythema,vesicles and occasional erosions with bilateral eyelid and oral involvement.Nikolsky's sign was positive.Wheezing sound was heard over the right lung.Genetic testing showed that HLA-B5901 allele was positive.The patient was diagnosed with methazolamide-induced toxic epidermal necrolysis (TEN) complicated by pneumonia,and managed with immunoglobulin (25 g/day,5 days),glucocorticoids (the largest dose equivalent to methylprednisolone 160 mg/day),fresh plasma,antibiotics,as well as other supporting and symptomatic treatments.The condition was controlled after 2 weeks,and the patient was cured and discharged from hospital after 25 days.The fact that the patient carried HLA-B5901 allele suggests that HLA-B5901 is strongly correlated with methazolamide-induced TEN or Stevens-Johnson syndrome in Chinese descendants or Han population,besides in Japanese and Korean descendants.
