Objectives To observe influences of two functionally important polymorphisms (5'-UTR and 3 -UTR) in thymidylate synthase (TS) gene and their combinative effects with drinking on the susceptibility of colorectal cancer (CRC). Methods A case-control study was designed, which included 140 CRC patients and 343 control subjects. Risk of CRC was estimated by unconditional Logistic model. Results The genotype distributions of the polymorphisms did not show significant differences between the cases and the controls. However, in those with -6 bp/-6 bp genotypes, the 2R carriers had a decreased risk (OR = 0. 60, 95%CI, 0. 23-1. 52) , but in +6 bp carriers, the 2R carriers had an elevated risk (OR=1. 87, 95%CI, 0. 94-3. 72). The likelihood test revealed the interaction existed between these two polymorphisms (P for interaction = 0. 05). Moreover, the combinative effect between the 3 -UTR polymorphism and alcohol drinking showed a significant association with the susceptibility of CRC (P for interaction =0. 01). In non-drinkers, the-6 bp allele carriers had a significant decreased risk (OR = 0. 57, 95%CI, 0. 32-0. 99) , but in ever and current drinkers, the +6 bp allele (6-bp insertion) carriers had an elevated risk (OR=1. 88, 95%CI, 0. 80-4. 41) , in which OR values ascended with the prolongation of drink-time. Conclusions The polymorphisms of thymidylate synthase at 5'-UTR and 3'-UTR may not be regarded as independent predictive factors for the susceptibility of CRC. However, interactions exist in these two polymorphisms and between the 3'-UTR polymorphism and drinking. Further studies with larger sample size and in different ethnic groups are needed.

Objective To study the compatibility of TCM prescriptions of TCM practitioners of all dynasties of Alzheimer disease (AD). Methods Amnesia, forgetting, dementia, and idiot were set as search words to retrieve relevant literature in Encyclopadia of Traditional Chinese Medicine. Prescription information was screened and standardized to build database. Frequency analysis and association rules were used to mine TCM prescriptions and compatibility rules. Results Totally 449 AD related prescriptions were selected, involving 682 Chinese medicinal herbs. The individual herb with the highest frequency was Ginseng Radix Rhizoma (192);the herbal pair with the highest frequency was Ginseng Radix Rhizoma-Polyhalae Radix (182);the herbal combination with 3 Chinese medicinal herbs with the highest frequency was Poria with Hostwood-Ginseng Radix Rhizoma-Polyhalae Radix (79);the herbal combination with 4 Chinese medicinal herbs with the highest frequency was Polyhalae Radix-Ginseng Radix Rhizoma-Poria with Hostwood-Glycyrrhizae Radix et Rhizoma (37). The results of association rules showed that Ginseng Radix Rhizoma-Polyhalae Radix, Ginseng Radix Rhizoma-Glycyrrhizae Radix et Rhizoma, and Ginseng Radix Rhizoma-Poria with Hostwood were commonly used compatibilities in AD related prescriptions. Conclusion Treatment of TCM practitioners in all dynasties for AD mainly chooses Chinese medicinal herbs with the efficacy of tonifying qi and soothing nerves. The compatibilities and combinations are reasonable and with certain representativeness.

Objective To investigate the clinical application of contrast enhanced ultrasonography (CEUS) in performing percutaneous biopsy for peripheral lung lesions. Methods A total of 132 patients with peripheral lung lesions underwent ultrasonography-guided percutaneous biopsy. Of the 132 patients, 72 received CEUS examinations before biopsy (CEUS group), and 60 received simple biopsy with no CEUS examination (control group). The ultrasonography imaging characteristics, the times of puncture biopsy, the diagnostic accuracy rate and the incidence of complications were recorded , and the results were compared between the two groups. The clinical value of CEUS in improving the success rate of percutaneous biopsy for peripheral pulmonary lesions was analyzed. Results Necrosis(areas of echoless) was demonstrated in 44.4%of the patients (32/72) in CEUS group, while it was displayed in only 6.7% of the patients (4/60) in the control group. The demonstration rate of necrosis in CEUS group were statistically higher than that in the control group (P <0.01). In CEUS group coexisting local pulmonary atelectasis was found in 12.5%of the patients (9/72), and the pulmonary lesion within the atelectasis could be clearly displayed. In the control group, local pulmonary atelectasis was demonstrated only in 1.7% of patients (1/60), the difference between the two groups was statistically significant (P<0.05). The diagnostic accuracy rate of CEUS group and the control group was 95.8% (69/72) and 80% (48/60) respectively, the difference was significant (P<0.01). The average number of punctures in CEUS group and the control group was (2.4 ± 0.6) and (2.6 ± 0.6) times respectively, the difference was not significant. The incidence of complications in CEUS group and the control group was 2.8% and 3.3%respectively, the difference was not significant. No severe complications occurred in both groups. Conclusion CEUS examination that is carried out before percutaneous pulmonary biopsy can effectively demonstrate the inner structure of the lesion, thus the diagnosis can be correctly made. Therefore, CEUS is of great value in guiding percutaneous pulmonary biopsy.
