Objective To investigate the imaging manifestations of lung neoplasms in pre- and post- treatment with CT-guided Argon-Helium cryoablation.Methods All the lung neoplasms in 96 patients have been treated with CT-guided percutaneous Argon-Helium targeted cryoablation.All patients have pre- and post-treatment CT scanning in measurement of lesion size and CT value.The CT scanning has been rerpeated afterl,3,6,12 months of treatment.Results Among total 96 cases,there are 82 cases of lung cancer and 14 cases of metastasis with 110 lesions(89 cases with single lesion,7 cases with multiple lesions).The Ar-He cryoablation has been given 103 times in total.The size of each lesion ranged from 1.2 cm to 15.0 cm in diameter with mean value of(4.0?2.5)cm,including 12 lesions less than 2 cm,51 lesions between 2— 4 cm,24 lesions between 4—6 cm,23 lesions over 6 cm.There are 25 patients whose lesions covered by iceball with 1 cm of overloaping it's margin.There are 63 lesions with diameter less than 4 cm gained 100% ablation rate,24 lesions with 4—6 cm diameter gained 95.8% ablation rate,and 23 lesions with over 6 cm diameter gained 69.6% ablation rate.The post-treatment CT show a progressively enlarged round,low density refrigerant area which clearly demarked with non- refrigerant area.The center of each refrigerant area has negative CT value,the mean decreased CT value of lesion instantly after the treatment are about 30— 50 HU with P

Objective To discuss the treatment of ureteropelvic junction obstruction by laparoscopic pyeloplasty. Methods A retrospective review of consecutive laparoscopic pyeloplasty in 102 patients between September 2001 and December 2007 was performed. The ureterpelvic junction was dissected and the obstruction portion was excised. Anastomosis was then performed through the ureter and the renal pelvis walls with a stent. Results The mean operating time was 120 min and the average blood loss was 80ml. No major complication occurred intraoperative. The drainage was removed in 3-10 days. The average hospital stay was 8.5 days. The stent was kept for 30-60 days. IVU and B ultrasound examination revealed that the hydronephrosis alleviated during the follow-up and no anastomosis stricture occurred. Conclusions Laparoscopic dismembered pyeloplasty could provide lower morbidity, shorter hospital stay, and faster convalescence. It could be an effective treatment for ureteropelvic junction obstruction.

OBJECTIVETobacco smoking results in increased platelet aggregability, which suggests that low-dose aspirin used in common clinical practice may not effectively inhibit platelet activity in smokers with coronary heart disease (CHD). This review was performed to assess the effect of aspirin on platelet aggregation in patients with CHD.

DATA SOURCESWe performed an electronic literature search of MEDLINE (starting from the beginning to March 15, 2009) using the term "smoking" or "tobacco" paired with the following: "platelet", "aspirin" or "coronary heart disease".

STUDY SELECTIONWe looked for review articles regarding the effect of tobacco smoking on platelet activity and on the anti-platelet efficacy of aspirin in healthy people and patients with CHD. The search was limited in "core clinical journal". In total, 1321 relevant articles were retrieved, and 36 articles were ultimately cited.

RESULTSTobacco smoking results in increased platelet aggregability, which can be inhibited by low-dose aspirin in the healthy population. However, in patients with CHD, the increased platelet aggregability can not be effectively inhibited by the same low-dose of aspirin. A recent study indicated that clopidogrel or an increased dose of aspirin can effectively inhibit the increased platelet aggregability induced by tobacco smoking in patients with CHD.

CONCLUSIONSIt is important for patients with CHD to quit smoking. For the current smoker, it may be necessary to take larger doses of aspirin than normal or take an adenosine diphosphate receptor inhibitor along with aspirin to effectively inhibit the increased platelet activity.

OBJECTIVEto evaluate the corrosion resistance of a new titanium alloy for dental restoration in artificial saliva.

METHODSin simulated oral environment, the electrochemical behavior of a new titanium alloy (Ti-12.5Zr-3Nb-2.5Sn) for dental restoration based on the d-electron alloy design method with high elastic modulus, high mechanical and good biological safety properties was investigated together with that of Ti-6Al-4V and TA2 as control groups. The anodic polarization curve and polarization resistance of these alloys were analyzed and the element release of Ti-12.5Zr-3Nb-2.5Sn and Ti-6Al-4V alloy after immersion in artificial saliva for 1, 2, 3, 5, 7, 15 d were measured.

RESULTSpolarization curve indicated that Ti-6Al-4V alloy had lower breakdown potential (0.8 V) than Ti-12.5Zr-3Nb-2.5Sn alloy did (> 2.5 V). Ti-6Al-4V alloy showed higher passivation current density (1.45 × 10(-4) - 1.09 × 10(-3) A/cm(2)) than Ti-12.5Zr-3Nb-2.5Sn alloy (3.32 × 10(-6) - 3.46 × 10(-5) A/cm(2)) and TA2(5.03 × 10(-6) - 2.65 × 10(-5) A/cm(2)) did. Polarization resistance results showed that polarization resistance volume of TA2, Ti-12.5Zr-3Nb-2.5Sn alloy and Ti-6Al-4V alloy were 371.0, 252.0, and 60.1 kΩ×cm(2) respectively. With the increasing of dipping time in artificial saliva, the ion release of Ti-12.5Zr-3Nb-2.5Sn alloy and Ti-6Al-4V alloy increased to different degrees. Ti-6Al-4V alloy always showed more ion release than Ti-12.5Zr-3Nb-2.5Sn alloy did in the experiment.

CONCLUSIONSdata from this study indicated that Ti-12.5Zr-3Nb-2.5Sn alloy, as a dental restoration material, had good corrosion resistance in artificial saliva.

A highly sensitive liquid chromatography-tandem mass spectrometric (LC-MS/MS) method was developed for the determination of actinoside E in rat plasma. The analytes were extracted by ethyl acetate and an analogue of actinoside F was used as the internal standard. The mobile phase consisted of methanol-water (50: 50, V/V) containing 0.1% formic acid was delivered at a flow rate of 0.3 mL·min(-1) to a Zorbax SB-C18 column (100 mm × 2.1 mm, 3.5 μm). The detection was performed by electrospray ionization mass spectrometry in the negative multiple reaction monitoring mode with a chromatograph run time of 3.0 min. Calibration curves of actinoside E were linear in the range of 0.5-2 500 ng·mL(-1). In this range, intra- and inter-day precision ranged from 1.7% to 7.5% and 2.0% to 8.9%, respectively. The accuracy ranged from 95.7% to 108.6%, and extraction recovery from 83.2% to 85.5%. This method was successfully applied to a pharmacokinetic study of actinoside E in rats after intravenous (5 mg·kg(-1)) and oral (100 mg·kg(-1)) administration, and the results showed that actinoside E was poorly absorbed with an absolute bioavailability being approximately 0.27%.

OBJECTIVETo examine granulocyte colony stimulating factor (G-CSF) expression in human non-small cell lung cancer (NSCLC) as well as discuss its clinicopathological significance.

METHODSSpecimens were obtained from 114 cases (53 cases with granulocyte infiltration) diagnosed pathologically as NSCLC in General Hospital of PLA. Paraffin-embedded tissues from these 114 cases of NSCLC were examined for expression of G-CSF by immunohistochemical staining. Correlation between G-CSF expression and pathological features, clinical manifestation, prognosis of patients with NSCLC was analyzed statistically. All the patients were retrospectively followed-up.

RESULTSFifty-five of the 114 NSCLC specimens expressed G-CSF, and among these 41 (41/54, 75.9%) were large cell carcinoma, nine (9/30, 30.0%) were adenocarcinoma and five (5/30, 16.7%) were squamous cell carcinoma. The expression was significantly correlated with infiltration of tumor mass by neutrophilic granulocytes, histological type, necrosis, differentiation, lymph node metastases, distant metastases, recurrence and survival period (P < 0.01). There was no significant correlation with primary tumor size (P > 0.05). Logistic multi-factor analysis revealed that necrosis, lymph nodes metastases and distant metastases RR (risk ratio) in G-CSF positive group was 5.57, 6.28 and 5.24 times higher than those of G-CSF negative group (P < 0.05). There were remarkable difference of 5-year survival rates (0 and 12.1% respectively) and survival period (42 and 62 months respectively) between positive and negative groups (P < 0.01).

CONCLUSIONSNSCLC with G-CSF excretion are mainly large cell lung cancer. The pathologic characteristics of these cases with G-CSF expression included poor differentiation, remarkable atypia, prominent necrosis and infiltration of tumor mass by neutrophils or emperipolesis. These tumors are usually more aggressive in biological behavior and have worse prognosis than those without G-CSF expression.

OBJECTIVETo investigate the expression of PTEN and loss of heterozygosity (LOH) of its epigenetic microsatellite in gastric carcinoma and explore their roles in progression of gastric carcinoma.

METHODSLOH of epigenetic microsatellites of PTEN (D10S541, D10S583 and D10S1687) in advanced gastric cancer was detected by PCR-SSCP. Expression of PTEN mRNA and protein in normal gastric mucosa and gastric cancer was evaluated by RT-PCR and SABC immunohistochemistry, respectively. The relationship between expression of PTEN mRNA and protein and lymph node metastasis or LOH of microsatellites was discussed.

RESULTSLOH of D10S541, D10S583 and D10S1687 was found in 37.5% (21/56) of advanced gastric cancers. The positive rates of PTEN mRNA expression were 80.4% (45/56), 45.5% (5/11) and 32.1% (18/56) in normal mucosa, early and advanced gastric carcinomas, respectively, while 78.6% (44/56), 44.5% (5/11) and 28.6% (16/56) at the protein level. PTEN mRNA and protein were less frequently expressed in early and advanced gastric carcinomas than that in normal gastric mucosa (P < 0.05). There was positive correlation between PTEN mRNA expression and LOH of microsatellites in advanced gastric carcinomas. PTEN protein expression paralleled with its mRNA expression (P < 0.05). The expression of PTEN mRNA and protein was negatively correlated with lymph node metastasis of advanced gastric carcinomas (P < 0.05).

CONCLUSIONDown-regulated expression of PTEN gene is found in different stages of gastric carcinoma, and is closely correlated with LOH of its epigenetic microsatellites, which probably is its underlying molecular mechanisms. It suggests that altered PTEN gene contributes to tumorigenesis and progression of gastric carcinomas.
