Objective To study microsatellite instability(MSI) in multiple primary colorectal carcinoma(MPCC) and solitary colorectal tumor(SCT), and to explore the relationship between the expression of mismatch repair(MMR)、p53、Bax、PCNA and MSI. Methods The expression of MMR、p53、Bax、 PCNAwere detected by immunohistochemical staining, and MSI at five microsatellite loci were examined by PCR-SSLP in 51 tumors from 38 MPCC patients and 35 SCT cases. Results The replication errors positive phenotype was observed in 27 of 51(53%) tumor foci from MPCC cases, and in 6 of 35(17%) SCT cases. There was an inverse correlation between replication errors (RER) positive and expression of p53; the PCNA labeling index of RER positive tumors were significantly lower than of RER negative tumors; RER positive related strongly with poor differentiation, the proclivity for proximal colon. Conclusions MSI may play an important role in the development of MPCC and may be used as a tumor marker of MPCC.

Objective To investigate Insertion/Deletion (InDel) polymorphism on the X chromosome and to screen 18 InDel loci for the Chinese Han population as a forensic DNA typing system auxiliary. Meth-ods Eighteen X-InDel markers were selected using the Human Genome Browser and dbSNP database. Multiplex PCR primer pairs of selected X-InDel markers were designed using Primer 3 software and di-vided into 3 groups according to the amplified fragment length, labeled by FAM, HEX and TAMRA fluorescence dye, respectively. The population genetics research and comparative analysis of Chinese Han nationality and 4 main minorities, the Hui, Wei, Mongol, and Tibetan nationalities, were investigated with the system. Results A new multiplex genotyping system, named InDel X-18PLEX, was successfully developed and validated, consisted of 18 X-InDel markers on the X chromosome and 1 Amelogenin gen-der marker. No deviation from Hardy-Weinberg equilibrium expectations was detected in the distribution of genotypes in the 5 investigated ethnic groups. However, there was significant difference between their distributions. From the investigation of Han nationality, high female (0.999 999 4) and male (0.999 88) overall discrimination power values were obtained, as well as high overall mean exclusion chance values in trios (0.999 992) and in duos (0.99). Conclusion InDel X-18PLEX meets the requirements as a forensic DNA complementary kit, providing effective supplementary analytical tools for difficult cases.

OBJECTIVETo investigate the expression of thymidylate synthase (TS) in patients with advanced lung adenocarcinoma and its relation with the therapeutic effect of pemetrexed.

METHODSThe clinicopathological data of 38 patients with stage IIIIB/IV lung adenocarcinoma receiving pemetrexed treatment were retrospectively analyzed. The tumor samples of the patients were collected for detecting TS expression using RT-PCR, and the therapeutic effect of the treatment was analyzed.

RESULTSTS positivity was found in 26.32 (10/38) of the patients. TS positivity was not correlated to gender, TNM stage or PS score. The total response rate of pemetrexed treatment (CR+PR) was 34.21 (13/38) in these patients, and the rate was 39.29% (11/28) in TS-negative patients, as compared to 20.00% (2/10) in the positive patients (P=0.087). Patients with low TS expression had significantly higher control rate by pemetrexed treatment than those with TS overexpression [89.29% (25/28) vs 40.00% (4/10), P=0.002].

CONCLUSIONTS expression may serve as a potential indicator of chemosensitivity to pemetrexed in patients with advanced lung adenocarcinoma.

OBJECTIVE: To evaluate the forensic application value of 30 insertion/deletion (InDel) loci included in Investigator DIPplex Kit in Han and She nationalities of Eastern China. METHODS: A total of 565 unrelated individuals in Han nationality and 119 ones in She nationality of Eastern China were investigated using Investigator DIPplex Kit. Allele frequencies, population genetics parameters of the 30 InDel loci were statistically calculated. RESULTS: In Han nationality, the mean Ho was 0.413 3, the mean DP was 0.551 1, the mean PIC was 0.320 0. And in She nationality, the mean Ho was 0.389 6, the mean DP was 0.543 3, the mean PIC was 0.310 0. No deviation from Hardy-Weinberg equilibrium was observed in Han and She nationalities (P > 0.05). CONCLUSION The 30 loci in Investigator DIPplex Kit show good genetic diversity in Han and She nationalities, and could be used as a supplemental tool for some special paternity cases.

OBJECTIVETo survey an outbreak of acute gastroenteritis in Lulong County and analyze the cause of the disease.

METHODSEpidemiological methods were applied to investigate an outbreak of acute gastroenteritis occurred in June 2000 in Lulong County. Stool specimens were collected from diarrhea patients and were tested for human calicivirus by ELISA and RT-PCR. The products of RT-PCR were cloned and sequenced, then phylogenetic analysis was carried out.

RESULTSIn total, 736 farmers were surveyed, among them 134 had acute gastroenteritis, the attack rate was 18.20%, and one elderly patient died. The age of patients was from 1 to 77 years and the incidence of the disease among young people was higher with a peak in June 25 through 30. Six stool specimens were tested for caliciviruses by ELISA and 3 were positives, one of them was confirmed by RT-PCR and belonged to norovirus genotype GI/2. No other pathogens were detected.

CONCLUSIONHuman calicivirus was confirmed to be the cause of the outbreak of acute gastroenteritis.

OBJECTIVETo objectively evaluate the clinical efficacy of stiletto needle for pain of knee osteoarthri tis (KOA), and analyze its function mechanism.

METHODSSeventy-six cases of KOA (76 knees) were selected. Under the guide of Jingjin theory in TCM, stiletto needle was applied at pain point of Jingjin in extra-articular area to have a loose solution effect, 1 to 3 points were selected each time, 1 to 2 times of treatment were required. The results of tenderness measurement instrument was adopted as main evaluation index of joint pain, and all data of evaluation indices before and after the treatment were statistical analyzed.

RESULTSThere were significant differences in visual analogue scale (VAS) score, tenderness score, HSS function score and movement range of joint before and after the treatment (all P < 0.05). The effective rate of stiletto needle therapy was 89.5%. There was apparent regression trend between VAS score and tenderness score with Y (VAS) = 7.841-1.569 X (tenderness score) as its regressive equation.

CONCLUSIONThe stiletto needle therapy is an effective method to relieve the pain of knee osteoarthritis, and its clinical efficacy evaluation could be more objective and digital with tenderness measurement instrument.
