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

ObjectiveTo study the reliability to asses s interstitial fibrosis in myocardium of advanced age spontaneous hypertension rats(SHR) by acoustic densitometry. MethodsFifteen 20-month-old spontanous hypertension rats and fifteen age matched Wistar Kyoto(WKY) as control group were included. Ultrasonic backscatter parameters were acquired at interventricular septum, left ventricular posterior wall, left ventricular lateral wall. Normalized values of integrated backscatter of left ventricular lateral wall were compared with results by stereological approach under eletronic and light microscope. Results Compared with control group, SHR group showed different integrated backscatter at interventricular septum, left ventricular posterior wall and left ventricular lateral wall(P

Objective To investigate the reconstructive method with better sensory and erectile function for partial penile defect. Methods The procedure was as follows: dissecting the suspensory ligaments and separating part of crus,the local fat flap was transferred to fill the front space of symphysis ossium pubica.Various pedicle skin flaps were designed as covering materials.Penis residual stump was advanced to anterior portion of the newly reconstructed penile body as “glans”.The post-operative follow-up included taking full layer skin of penis from the patients to observe neurofibril regeneration by light microscope, electron microscope and scanning electron microscope;determining sensation recovery by physical examination;and checking erectile function with NEVA system. Results 42 patients underwent the above mentioned procedures.In these cases,the length of the penis varied from 0.5～4.0 cm in flaccid,1.5～5.0 cm in erect state before operation to 5.0～8.0 cm in flaccid,7.0～12.5 cm in erect state after operation.28 patients were followed up for more than 1 year.Of them 23 men got married with acceptable sexual activity;in them 18 had their children.The microscopic examination showed that the tenuous wavy peripheral nerves were well differentiated and no denaturation and necrosis were observed in the dermis,near subcutaneous adipose and around eccrine glands.The positive granules could be seen in the cytoplasm of regenerative neurofibrils by immunohistochemistry technique.The regenerative neurofibrils and related tissues could be seen under scanning and transmission electron microscope.The penis presented normal pain,touch feeling and 2-point identification ability in more than 12 months after surgery.Over 12 months after surgery,the patient had gained 4～9 events during 8～12 hours of sleep, and the durations were 4 to 37 min;the volume changes were from 114% to 505% over baseline. Conclusions With this method,the reconstructed penis tends to have better appearance and functions.For penile partial defect it is superior to the conventional operation.
