The TNM staging is the most common tumor staging system of lung cancer.The new revisioned 7th lung cancer TNM staging is published by the international association for the study of lung cancer (IASLC) in the 13th world conference on lung cancer.Accurate clinical staging depends on the multi-analysis from medical histroy,clinical examination,imaging examination and invasive test,which has important significance for guiding the treatment of lung cancer.The 7th lung cancer TNM classification has been revised respectively from the primary focus,lymph node metastasis and remote viscera metastasis,so as to make it more accurately corresponding to the prognosis of patients.

Objective To observe the clinical effect of herbal decoction Sishen Jian on acute osteoarthritis of knee joint.Methods The 60 osteoarthritis cases in the attack stage were randomized into treatment group(30 cases)and control group(30 cases).The treatment group was given the decoction Sishen Jian and Diclofenac Sodium Sustained Release Capsules and the control group was given the capsules only.Two weeks made one course of treatment.Before and after treatment,the symptoms such as pain and morning stiff- ness,the signs including joint swelling and tenderness,and the erythrocyte sedimentation rate(ESR)and C reactive protein were ob- served for comparison.Results The total effective rate of the treatment group and control group was 96.66% and 53.26% respec- tively.The difference of two groups was significant(P

OBJECTIVE: To use montmorillonite as the carrier of matrine. METHODS: Urea was used to insert into the montmorillonite interlayer by solid-phase grinding method. After this process, the matrine was loaded by the solution blending to obtain montmorillonite/matrine nanocomposite. RESULTS: XRD and FT-IR showed that the urea was intercalated into the montmorillonite layers, and the interlayer spacing of montmorillonite was enlarged from ca. 1.2 to 1.7 nm. With the help of the urea, the matrine was successfully loaded into the montmorillonite layers, at the same time the interlayer distance of the montmorillonite was further increased to 1.86 nm. In vitro release experiments displayed that the release of montmorillonite/matrine composite accorded with the Higuchi e-quation, indicating that the montmorillonite could sustain the release of matrine. MTT measurement showed that the montmorillonite/matrine nanocomposite has significant cytotoxicity on human gastric cancer cells (SGC7901). CONCLUSION: This research suggests the feasibility of montmorillonite as the sustained release carrier for the matrine and other alkaloids drug, and provides the evidence for montmorillonite in the pharmaceutical field as drug carriers.

Objective The aim of this study was to explore the effect of androgen deficiency on serum hormone levels, visceral fat accumulation and inflammatory gene expression in miniature pigs fed a high-fat diet ( HFD) . Methods Sexually mature male Chinese Wuzhishan miniature pigs were divided into three groups ( animals/group) as follows:intact male pigs ( SHAM) , castrated male pigs ( CAS) and castrated male pigs plus testosterone treatment ( CAS+T) . The pigs were fed a HFD diet for 12 weeks. Serum levels of testosterone and leptin were measured and visceral fat were dissected and weighted. qRT?PCR was performed to determine the mRNA expression levels of lipogenic, lipolysis and inflammation relat?ed genes. Results (1) Serum testosterone levels were significantly decreased but serum leptin levels were significantly in?creased in the castrated pigs. These effects were recovered after testosterone treatment. ( 2 ) Visceral fat percentage was significantly increased in the castrated pigs, and testosterone treatment reduced the increased visceral fat in the castrated pigs. (3) Castration and testosterone treatment had no significant effects on the expression levels of lipogenic genes (FAS and ACC) and lipolysis genes (HSL and ATGL) in pigs fed a HFD. (5) Castration significantly induced the expressions of inflammatory genes including Leptin, CD68, CCL16, CCL23 and SAA, and testosterone treatment recovered the expres?sions of the above genes in the castrated pigs. Conclusions Castration?induced testosterone deficiency promotes visceral fat accumulation and upregulates the expression levels of inflammatory genes in miniature pigs fed a HFD. Moreover, tes?tosterone treatment ameliorates castration?induced visceral fat accumulation and inflammatory response in HFD?fed pigs.

Objective To understand the microorganisms pollution and the community structure and distribution characteristics of airborne microbes in forest scenic spot in Huangshan,China.Methods The airborne microbes were sampled by fallen plate method from 2002 to 2003 in Huangshan scenic area and Hefei city.Results The results showed that there was a significant negative correlation between the elevation and airborne microbe,the relative coefficient was -0.580(P

As we known,serum creatinine(Scr),serum urea nitrogen(SUN) and creatinine clearance rate(Ccr),the most established marker of renal function,are affected by age,gender,muscle mass or nutritional status.Scr determines the glomerular filtration rate(GFR) improperly.Serum Cystatin C(sCys C) is freely filtered at the glomerulus and then resorbed and fully catabolised by proximal renal tubules,ma-king it an ideal marker of GFR.It is not affected by gender,muscle mass or malignancy,its production rate is usually constant and its plasma concentration therefore is dependent only on GFR.sCys C has been demonstrated to be more accurate and sensitive than Scr in the detection of early renal impairment and in specific populations may allow for early detection of renal disease.The aim is to discuss the advantages and limitations of sCys C and of established GFR methods.

This article introduces how to use debate in clinical teaching and explains the organization,training,choosing the debate topics,making the rule and implementation of debate.Debate is advantageous to raise and enhance the medical students' abilities of study independent,clinical thought,consult,analysis and application literatures,oral expression,team cooperation and so on.
