Objective To study the clinical efficacy of full thoracoscopic lobectomy and thoracotomy in treat-ment of non -small cell lung cancer.Methods 200 patients with non -small cell lung cancer were divided into group A and group B according to the different surgical methods,with 100 cases in each group.Group A was given the full treatment thoracoscopic lobectomy,group B was received treatment thoracotomy.Pain situation were evaluated in visual analog scale(VAS)method,clinical efficacy and adverse reactions of the two groups were compared.Results The intraoperative blood loss,operative time,drainage,VAS scores and hospital stay of group A were (253.4 ± 1.9)mL,(181.3 ±9.3)min,(174.6 ±4.2)mL,(4.2 ±1.4)points and (7.2 ±0.6)d respectively,which were significantly better than (409.3 ±2.4)mL,(232.2 ±3.2)min,(312.9 ±2.5)mL,(6.3 ±0.9)points and (13.5 ± 0.6)d of group B,the differences were statistically significant(t =8.928,9.028,8.232,9.701,10.906,all P <0.05).The lymph node metastasis number and the number of lymph node dissection of the two groups had no statistically significant differences(t =2.098,3.092,2.983,all P >0.05).The incidence of complications of group A were significantly lower than those of group B,the difference was statistically significant(χ2 =9.033,P =0.002). Conclusion Full thoracoscopic lobectomy in the treatment of non -small cell lung cancer has better effect compared with thoracotomy,its harm to patients is small,and has fewer postoperative complications.

Objective To investigate the value of contrast enhanced ultrasonography in evaluating cystic renal mass. Methods According to the imaging diagnosing standard, 29 cystic renal mass lesions were studied with contrast enhanced ultrasonography(CEUS), unenhanced ultrasonography (US), contrast enhanced CT(CECT) and then correlated their results with final histopathological results. The data were tested by receiver operating characteristic(ROC) curve. Results The area under ROC curve of CEUS and US was 0. 721, 0. 997, respectively. There was significant difference between the 2 groups (P=0. 003). The area under ROC curve of CEUS and CECT was 0. 997, 0. 997,respectively. There was no significant difference between the 2 groups (P= 1. 000). Conclusions CEUS is better than US and similar to CECT in evaluating cystic renal mass. CEUS with the Bosniak classification is useful for evaluating cystic renal mass.

Tibetan Herbal medicine has its own complete theory based on five sources doctrine. And the theories of "Liuwei", "Baxing" and "Shiqi Gongxiao" formed the basic core components of the property theory of Tibetan medicine. However, books and literature of Tibetan medicine have never been systematically expounded and discussed about it specially which thus will limit the further development of Tibetan medicine theory. In this thesis, we firstly introduced three basic core components of the property theory-the "Liu Wei", "Baxing", and "Shiqi Gongxiao" and their interactions as well. At the same time, the links and similarities between the theory of Tibetan medicine and Chinese medicine theory were compared. The job of the thesis done above is to lay the foundation for further systematic reveal and development of Tibetan medicine theory.

To investigate the characteristics of scale cataract operations and the effects and experiences of small incision extracapsular cataract extraction with intraocular lens ( lOL) implantation in large - scale vision recovery action.
●METHODS: Four thousand eight hundred ninety - two cases ( 4892 eyes ) of cataract were treated by small incision non-phacoemulcification cataract extraction from March 2010 to November 2011 in our hospital ( Fuming No. 1 surgery car of Shaanxi Province ) which were retrospectively analyzed. Visual acuity, intraoperative and postoperative complications, the recovery of postoperative inflammation were observed.
●RESULTS: Visual acuity reached 0. 3 or more in 4521 eyes (92. 42%) at 1d after the operation, at 3d after the operation in 4571 eyes (93. 44%), there were 4887 eyes with lOL implantation, implantation rate was 99. 90%. All the cases had lesser intraoperative and postoperative complications, and the postoperative inflammation recovered quickly.
●CONCLUSlON: Small incision extracapsular cataract extraction with lOL implantation is simple, effective, economical, safe and adapting for large - scale vision recovery action.

BACKGROUND: Recently, trans-pedicle screw internal fixation has markedly improved the rigidity of spinal fixation and hence the fusion rate. But when placed incorrectly, the pedicle screw can injure the spinal cord and/or nerve roots, resulting in serious complications.OBJECTIVE: To evaluate the application value of preoperative CT scans-based navigation technique in the spinal pedicle screw internal fixation surgery.DESIGN, TINE AND SETTING: A prospective, randomized, and controlled observation was performed at the Department of Orthopedics, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences between January 2006 and December 2008.PARTICIPANTS: A total of 95 patients who underwent pedicle screw internal fixation due to spine diseases were randomly assigned to a navigation group (n = 45) and a conventional group (n = 50).METHODS: In the navigation group, patients were subjected to pedicle screw insertion with the assistance of computer navigation technique and while in the conventional group, patients underwent pedicle screw insertion using the conventional anatomic landmark combined with fluoroscopy.MAIN OUTCOME MEASURES: Screw channel preparation time, excellent and good rate of screw position, and postoperative complications.RESULTS: In the navigation group, totally 206 pedicle screws were inserted under navigation guidance, with an excellent and good rate of 96.1%; and navigation could not be continued in 9 patients for a three-dimensional registration error. In the conventional group, altogether 285 pedicle screws were inserted, and the excellent and good rate was 100%. No significant difference was found between the two groups (P > 0.05). The navigation group exhibited longer screw channel preparation time than the conventional group [(360±22) seconds vs. (56+8) seconds, P < 0.01]. No postoperative complications were found in each group.CONCLUSION: The preoperative CT scans-based navigation technique produces similar accuracy of pedicle screw insertion, but markedly prolonged operation time, compared with the conventional anatomic landmarks, exhibiting limited application value in the spinal pedicle screw internal fixation.

OBJECTIVETo obtain the data of the genotypes and allele frequencies of 9 short tandem repeat (STR) foci (D18S1364, D12S391, D13S325, D6S1043, D2S1772, D11S2368, D22-GATA198B05, D8S1132, and D7S3048) in Chinese subjects of Li and Han nationalities in Hainan Province.

METHODSA total of 154 randomly selected unrelated subjects of Li nationality and 112 unrelated local Han subjects from Hainan Province, along with 125 Han subjects recent immigrated to Hainan were enrolled in this investigation. Venous blood samples were obtained from the subjects to determine the allele frequencies at the 9 STR loci using multiplex primer extension assay. Statistical analysis was performed to determine the observed heterozygosities (Hobs), polymorphism information content (PIC), individual identification probability (Dp), accumulated power of discrimination, and cumulative rate of exclusion. The genetic polymorphisms of the 9 STR loci was analyzed to acquire the population genetics data.

RESULTSThe genotype and frequency distributions of the 9 STR loci were consistent with Hardy-Weinberg equilibrium. The Hobs, PIC, Dp, cumulative rate of individual identification (CDP), and cumulative chance of exclusion (CCE) showed no significant difference between the 9 foci.

CONCLUSIOND18S1364, D12S391, D13S325, D6S1043, D2S1772, D11S2368, D22-GATA198B05, D8S1132, and D7S3048 STR loci in Chinese Li and Han population in Hainan Province show a high probability of personal identification without obvious difference between the populations, suggesting their value in forensic science and population genetics.
