Objective: To investigate clinical significance of microRNA-130b (miR-130b) in osteosarcoma and its role in cell growth and invasion. Methods: miR-130b expression was detected in 68 samples of surgically resected osteosarcoma and matched normal tumor-adjacent tissues by qRT-PCR. The expression of miR-130b was altered by corresponding vectors in osteosarcoma cells, and then Western blot was used to detect the expression of PPARγ. BrdU cell proliferation and Transwell assays were performed to determine cell proliferation and invasion. Results: The expression of miR-130b in osteosarcoma tissues was significantly higher than that in normal tumor-adjacent tissues. Its expression in patients with metastasis was significantly higher than that in those without metastases. miR-130b expression in tumor tissues was significantly associated with tumor size, clinical stage and distant metastasis. And its expression was significantly correlated with overall survival and disease free survival. miR-130b overexpression obviously repressed the expression of PPARγ, and resulted in significant increase of Saos-2 cell proliferation and invasion. On the contrast, repressing miR-130b expression with its inhibitor significantly increased PPARγ expression, and inhibited MG-63 cell proliferation and invasion. Conclusions: The high-expression of miR-130b is correlated with the adverse clinicopathological features and poor prognosis in osteosarcoma. miR-130b may regulate proliferation and invasion of osteosarcoma cells by targeting PPARγ, suggesting miR-130b may play a key role in the progression of osteosarcoma.

From original concept and literature of acupoint, the concept and clinical significance of ashi method is discussed, which clarifies that the essence of ashi method is to locate the acupoints by patients' sensitivity on force. The clinical application of heat-sensitive moxibustion has illustrated that positioning method of this therapy is based on the appearance of heat-sensitive moxibustion sensation. Although both types are based on patients' feeling, positioning method of heat-sensitive moxibustion stands on a new angle and uses a new method to locate acupoint. Therefore, it is believed that the positioning method of heat-sensitive moxibustion is the inheritance and development of ashi method.

OBJECTIVETo analyze the polymorphism of natural killer cell immunoglobulin-like receptor (KIR)gene and the characteristics of its genotypes and haplotypes in Korean ethnic group of Jilin area, and to compare with that of Han nationality.
METHODSDNA samples randomly collected from 214 Han and 160 Korean populations were genotyped with PCR-SSP method, and KIR genotypes and haplotypes were assigned according to the standard model by Hsu et al.
RESULTSAll individuals contain KIR 3DL3, KIR 2DL4, KIR 3DL2 with the genotype frequency of 100%; the most common genotypes were 2DL1, 2DL3, 3DL1, 3DP1(*)003 and 2DP1; the genotypes with low frequency were 2DL2, 2DS2, 2DS3, 3DP1(*)001/002/004. Thirty-nine different KIR genotype and 16 haplotypes had been found in Korean and Han individuals. The most common KIR genotypes were AJ and AF with frequency of 18.1%, 19.4% and 31.8%, 19.6%, respectively. The most common KIR haplotype was haplotype 2 with frequency of 41.8% (n = 127) and 51.2% (n = 216) (P < 0.05), respectively.
CONCLUSIONKIR gene distribution in Jilin Korean ethnic group showed some common features of KIR gene polymorphisms in Chinese Han population, but also showed this nation's unique characteristics of KIR gene polymorphism.

The primers and probes for the Real-time RT-PCR were designed based on the multiple sequence (swine and humans HEV strains) alignments of the ORF3 region of genotype 4 HEV. A rapid, sensitive and stable TaqMan Real-time RT-PCR assay was established, and its specificity and sensitivity were assessed, and comparison of the Real-time RT-PCR with conventional and nested RT-PCR was performed. The results found that the crossing points showed linearly proportional to the logarithm of the input copy number. The correlation coefficient (R2) and the slope value of the standard curves with plasmid DNA were 0.994 and -3.312, respectively. The efficiency (E) of the PCR was 100%. Coefficients of variation values of the different diluted plasmid DNA were low in the same or different repeated experimental group. In addition, the assay was able to correctly detect genotype 4 HEV RNA from swine fecal samples. The sensitivity of established assay was 100-fold higher than that of conventional RT-PCR and 10-fold higher than nested RT-PCR.
