Objective To investigate the effects of previous open nephrolithotomy on the technical features, outcomes and morbidities of subsequent percutaneous nephrolithotomy (PCNL). Methods Ninety-eight patients who underwent PCNL from January 2006 to January 2011 were selected in this study. The 34 patients of them who had previous open nephrolithotomy on the same kidney were assigned as group A, and the other 64 patients who had no previous open surgery as group B. The data of operation time, blood transfusion quantity, residual stones rate, hospitalization time and time of tube evulsion were collected and compared between the two groups. Results There were no significant differences between the group A and B with respect to the mean operative time [(84.0±24.6) min vs. (94.0±22.7) min, t=1.372, P=0.177], hospitalization time [(6.5±1.1)days vs. (6.3±1.8)days, t=0.49, P=0.261], blood transfusion quantity [(82.9±10.6) ml vs. (85.0±11.8) ml, t=0.415, P=0.682], kidney and colostomy channels [single channel(70.6% vs. 75.0%), double channel (29.4% vs. 25.0%), χ2 =0.22, P=0.638] and residual stones rate (5% vs. 3%,χ2=0.42, P=0.282). Conclusions When PCNL is performed after previous open nephrolithotomy, there is no difference in success rate and morbidities.

Objective To investigate the Raman spectral characteristics of the pathological lip minor salivary glands affected in primary Sjtǒgren's syndrome.Methods Thirty pathological samples and 30 normal samples were collected in this study.The samples were examined by Raman microscope.Support vector machine (SVM) was employed to analyze the data and establish the classification model.Results The spectra of pathological tissues was different from the controls in proteins,nucleic acids,lipids and glycogen skeleton.The sensitivity,specificity and accuracy of the model established by SVM on the training sets were all 92.0% (92/100),but the sensitivity,specificity and accuracy of the model established by SVM on the testing sets were 69.2% (37/53),100.0% (37/37) and 82.0% (73/89) respectively.Conclusions There was significant difference in Raman spectra between the pathological and normal lip salivary glands,and the classification model established by SVM could discriminate the pathological glands from the normal ones.

OBJECTIVETaxus species are highly valued for the production of taxol. Based on high-throughput sequenceing, EST-SSRs were explored and studied in the transcriptome of Taxus cuspidata.
METHODT cuspidata leaf cDNA was extracted and sequenced by 454 GS FLX Titanium. High-quality sequences were assembled using Newbler Assembler Software, which produced unique sequences. SSRs motif was explored using simple sequence repeat identification tool (Perl Script). Primers were designed using PRIMER3.
RESULTA total of 81 148 high-quality reads from the needles of T. cuspidata were produced using the Roche GS FLX Titanium system. A total of 20 557 unique sequences were obtained. There were 753 simple sequence repeat motifs identified. Primers of PCR were obtained for 519 EST-SSRs, randomly selected cloning sequencing revealed that 87.5% of ESTs were the same as the results of Sanger sequencing.
CONCLUSIONThe results provide the first EST-SSRs collection in Taxus and are essential for future efforts of gene discovery, functional genomics, and genome annotation in related species.

OBJECTIVETo study the expression of phosphatase and tensin homology deleted on chromosometen ten (PTEN) protein, a tumor suppressor gene in breast cancer and its correlation with p27(kip1) and cyclin D1 expression.
METHODSPTEN protein expression, p27(kip1) and cyclin D1 protein expression were detected by immunohistochemical method in paraffin sections from 61 women with primary breast cancer. PTEN protein expression was compared with clinico-pathologic parameters as related to p27(kip1) and cyclin D1.
RESULTSPTEN, being shown in the cytoplasm, was negative in 6.6% (4/61), reduced in 41.0% (25/61) and positive in 52.5% (32/61) samples. PTEN expression level was correlated with axillary lymph node status, loss of estrogen receptor stain, recurrence and metastasis. On univariate analysis, the disease-free survival rate of patients with higher PTEN expression (> 50% cells stained) was better than those with lower expression (P = 0.0101). However, there was no correlation between p27(kip1), cyclin D1 expression or PTEN expression.
CONCLUSIONPTEN, its lower expression being correlated with poor outcome of breast cancer patients, plays a prominent role in breast cancer. p27(kip1) or cyclin D1 may not be the primary downstream genes of PTEN in breast cancer.

Objective To explore the impact factors for post-thaw embryo survival rate and clinical pregnancy rate in frozen-thawed embryo transfer program. Methods The clinical data of 573 cycles of frozen-thawed embryo transfers were retrospectively analysed. Groups were divided according to the pre-freeze embryo quality, pre-freeze embryonic developmental stage, frozen-thawed embryo quality and cryopreservation technique, respectively, and post-thaw embryo survival rates and/or clinical pregnancy rates were compared among groups. Results The clinical pregnancy rate of high quality pre-freeze embryo was significantly higher than that of low quality pre-freeze embryo (31.8% vs 20.0%) (P< 0.05). There was no significant difference in the post-thaw survival rates and clinical pregnancy rates between embryos frozen at day 2 of ferrtilization and those frozen at day 3 of ferrtilization(79. 1% vs 82.9% and 25.5% vs 31.2%, respectively) (P>0.05). The clinical pregnancy rates of the transfer cycles only with fully intact embryos and with mixed embryos were significantly higher than that only with partially damaged embryos(36.7% vs 24.1% and 29.2% vs 24.1%, respectively)(P<0.05). The post-thaw survival rate and post-thaw high-quality embryo rate were significantly higher in those processed with modified cryopreservation technique than in those processed with original cryopreservation technique (82.0% vs 66.3% and 50.0% vs 27.5%, respectively)(P<0.05). Conclusion Pre-freeze embryo quality, post-thaw embryo survival rate and post-thaw embryo quality have a positive correlation to subsequent clinical pregnancy rate. Favorable cryopreservation technique may ensure the success of post-thaw embryo recovery and transfer.

OBJECTIVETo investigate the frequency of EML4-ALK fusion gene in non-small-cell lung cancer (NSCLC) patients, and its correlation with clinicopathologic features.
METHODSReal-time PCR was used to detect the presence of EML4-ALK fusion gene in 268 cases of NSCLCs using paraffin-embedded tissue samples(among which 164 samples were re-validated by Sanger sequencing). Related clinicopathological correlation was analyzed.
RESULTSEML4-ALK fusion gene was found in 4.1% (11/268) of the cases. One hundred and sixty four samples were verified by Sanger sequencing, and the overall coincidence of the results of two methods (Sanger sequencing and Real-time PCR) was 100%. Female patients (5.9%, 5/85), ≤ 60 years of age (4.3%, 6/140), non-smokers (6.8%, 8/118) and adenocarcinomas (7.6%, 10/132) had a higher mutation rate than that in male patients (3.3%, 6/183), > 60 years of age (4.0%, 5/124), smokers (1.6%, 2/132) and squamous cell carcinomas (1.3%, 1/79), although no statistical significance in age (P = 0.918), gender (P = 0.503), smoking history (P = 0.092) and histological type (P = 0.094).
CONCLUSIONSChinese NSCLC patients have a 4.1% detection rate of EML4-ALK fusion gene in the tumor tissues. Female, non-smoker and adenocarcinoma histological subtype tend to be associated with a higher rate of EML4-ALK gene fusion.
