Objective To investigate the expression of inhibitors of apoptosis (IAPs) in non-small cell lung cancer (NSCLC) patients and its clinical significance. Methods The mRNA expression level and protein level of survivin, hIAP-1 (human IAP-1), hIAP-2 (human IAP-2), and XIAP (X chromosome-linked IAP) in 36 NSCLC patients and 36 controls were analyzed by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) and Western blotting, respectively. Results High survivin mRNA expression were detected in 32 out of 36 patients, but not in controls. 26/36 NSCLC showed high XIAP mRNA expression and were significantly higher than those with benign diseases (P

Objective To evaluated the role of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis of thoracic tuberculosis.Methods The study was retrospective,from September 2009 to September 2012,38 patients who underwent EBUS-TBNA were finally diagnosed of thoracic tuberculosis,with enlarged hilar or mediastinal Iymph nodes on chest enhanced computed tomography(≥ 1.0 cm).Patients in whom EBUS TBNA was nondiagnostic subsequently underwent surgical biopsy.All the patients had a minimum of 6 months clinical and radiologic follow-up.Results EBUS-TBNA was performed on a total of 88 lymph node stations in 38 patients.Of the enlarged lymph nodes,60(68.18％) were located in the mediastinal region and the remaining 28 (31.82 ％) around the hilum or interlobar area.Of the 38 patients,EBUS-TBNA achieved definitive diagnosis in 34 patients(89.47％).EBUS was well tolerated by all of the patients with no complications.Conclusion EBUS-TBNA is a safe procedure with a high yield for the diagnoses of thoracic tuberculosis.

The contamination of extrinsic harmful contaminants including mycotoxins, heavy metals and pesticides, etc, brings serious risks to traditional Chinese medicines (TCMs), further to human health. Due to their unique photoluminescence, chemiluminescence, electrochemical and electrochemiluminescence properties, semiconductor quantum dots (QDs) nanoparticles are widely used to immobilize bioprobes and biosensors, etc. In this review, the luminescence characteristics and specific ligands of QDs probles which are used to determine contaminants were summed up. Then, the applications of QDs-coated novel probes in the determination of mycotoxins, heavy metals and pesticides were discussed in detail. In addition, the contamination levels and characteristics of extrinsic harmful residues in TCMs were investigated. Further, the maximum levels of those contaminants in TCMs were compared with those set by various countries. Finally, the future development trends and problems of QDs-coated probes in the determination of those extrinsic residues in TCMs were prospected.

OBJECTIVETo evaluate clinical outcomes of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction under arthroscopy combined with limited open repair of medial collateral ligament (MCL) for the treatment of multiple ligament injuries of knee joints.

METHODSFrom March 2006 and June 2012,the data of 14 patients (14 knees) with multiple injuries of ACL, PCL, and MCL were collected. There were 8 males and 6 females with an average age of (31.8 +/- 8.1) years old (ranged, 20 to 49 years old). All the patients were performed with X-ray and MRI examination, and the results showed that 10 patients had combined with injuries of anterior cruciate ligament (ACL), posterior cruciate ligament (PCL) and medial collateral ligament (MCL); 4 patients had ALC,PCL and posterolateral corner (PLC) injuries. Four patients had medial meniscus injuries and 2 patients had lateral meniscus injuries. The MCL,PLC and meniscus injuries were treated with operation on the first stage, and functional exercises were performed 3 weeks after fixation. The reconstruction operation of ACL and (or) PCL was performed at the second stage under arthroscopy 3 to 6 months later when the movement range of knee joint recovered to the normal level with obvious relaxation.

RESULTSAll incisions healed by primary intention. All the patients were followed up with a mean duration of 48.9 months (ranged, 24 to 80 months). The Lysholm score was improved from preoperative 19.6 +/- 0.9 to the latest follow-up 87.1 +/- 2.8 (t=12.3, P<0.01). The International Knee Documentation Committee (IKDC) rating: 9 cases nearly recovered to normal, 5 cases were abnormal.

CONCLUSIONFor multiple ligament injuries in the knee, staged repair and reconstruction can effectively restore knee joint stability and function.

0.05).The FMPV of the B?448 AA plus GA was higher than that of the GG type in obesity group(P0.05).Conclusions The simple obesity in children is associated with Fg and FMPV,which have become the high risk factors of the disease of heart and brain.The Fg B?448 G/A gene polymorphism may be an accumulative efficiency gene of children with simple obesity by influencing FMPV.

BACKGROUND: Osteoblasts derived from bone marrow stromal stem cells are the main force of the cells In bone marrow cavity.In the artificial joint replacement cases, their life situation is closely related to conductive pressure of prosthesis.OBJECTIVE: To observe the continuous pressure on the proliferation of rabbit's bone marrow stromal stem cells, and to reveal the biomechanism of continuous pressure causing loosening and sinking of prosthesis and its activity after replacement.DESIGN, TIME AND SE'I-I'ING: A randomized study based on cytology was performed at the Institute of Othorpaedics, the Fourth Military Medical University of Chinese PLA from February 2004 to October 2007.MATERIALS: One New Zealand rabbit aging 1 month and weighing 0.5 kg was used to extract the bone marrow stromal calls.METHODS: The third-passaged bone marrow stromal stem cells were inoculated in seven 24-well culture plates at the density of 1 × 104 cells/well. After 14 hours, cells were adherent completely and cultured in DMEM culture media containing 10% fetal bovine serum. Thereafter, the four culture plates were randomly divided into 4 experimental groups, including control group without any pressure, and continuous pressure (20, 60, and 100 kPa) groups. The continuous pressure was performed for 3 hours every day.MAIN OUTCOME MEASURES: Absorbance was detected at day 1, 3, 5, and 7 after culture using MTT assay.RESULTS: Absorbance of the three pressure groups after 3, 5 and 7 days was significantly lower than the control group (P < 0.01). There was no significant difference in absorbance between 20 kPa continuous pressure group and 60 kPa continuous pressure group on the third day (P >0.05); but the absorbance was significantly higher than 100 kPa continuous pressure group (P < 0.05). On the fifth day, there was significant difference in absorbance between paired continuous pressure groups (P < 0.05),i.e., the higher the continuous pressure was, the lower the absorbance was. On the seventh day, the absorbance of the 100 kPa continuous pressure group was significantly lower than 20 kPa continuous pressure group (P < 0.05).CONCLUSION: Patients with eady post-joint replacement had better not stand on the ground; otherwise, a continuous stress will be caused so as to induce the restrain of bone marrow stromal stem calls in the bone marrow cavity, which is not helpful for bone healing and easily causes subsidence and loosening of prosthesis.
