Objective:To observe the clinicopathological features of gastrointestinal stromal tumor (GIST) cases with concurrent carcinoma. Methods:Patient data of 24 GIST cases with concurrent carcinoma were collected from the 157 GIST cases reported be-tween 2002 and 2012. The clinicopathological features of the GIST cases with concomitant carcinoma were studied. The expression of CD117, CD34, and SMA by the tumors was assayed using the immunohistochemical EliVision method. In particular, the expression of the proliferation marker Ki-67 was studied. Results:GIST cases with concurrent carcinoma accounted for 15.3%of the total GIST cas-es studied. The GIST patients with concurrent carcinoma included 14 males and 10 females. The male-female ratio of these patients was 1.4∶1. The age of the patients ranged from 41 years to 66 years, with a median age of 55 years. Lesions at the inferior segment of the esophagus were found in 7 of the 24 selected GIST cases;lesions at the gastric wall and in the intestines were observed in 15 and 2 cas-es, respectively. The diameter of the GIST cases with concurrent carcinoma ranged between 0.6 and 3.8 cm, with an average of 1.50 ± 0.85 cm. Slight dysplasia was observed in 4 of the 24 cases; no heteromorphism was present in the remaining 20 cases. The mitotic counts of GIST cases with concurrent carcinoma ranged from 0/50 HPF to 5/50 HPF, with an average of (0.79±1.83)/50 HPF. The pro-liferative index of Ki-67 in the GIST cases with concurrent carcinoma ranged between 0 and 7.72, with an average of 2.16 ± 3.26. The concurrent carcinoma cases included 5 cases with esophageal carcinoma, 2 with cardiac carcinoma, 15 with gastric cancer, and 2 with intestinal cancer. In contrast to the GIST cases with concurrent carcinoma, the GIST cases without carcinoma complications included 74 males and 59 females. The male-female ratio was 1.25∶1. The age of the patients without concurrent carcinoma ranged from 43 years to 71 years, with a median age of 54 years. Among the 133 GIST cases without cancer complications, gastric, intestinal, and esophageal lesions were found in 114, 13, and 6 cases, respectively. The diameter of GISTs without cancerous complications ranged from 2.4 cm to 15.5 cm, with an average of 6.11 ± 7.09 cm. Different degrees of dysplasia were seen in 82 of the 133 cases. The mitotic counts in the GIST cases without cancer complications ranged from 0/50 HPF to 53/50 HPF, with an average of (3.81±23.67)/50 HPF. The prolifera-tive index of Ki-67 for these cases ranged from 0 to 39.21 and averaged at 6.22 ± 16.96. The male-female ratio of the GIST cases with cancer complications was higher compared with the GIST cases without. The average diameter of GISTs with complications was small-er compared with that of GISTs without complications. The mitotic counts and the proliferative index of Ki-67 were significantly lower in the GIST cases with cancer complications than in those without (t=1.981, P<0.05 vs. t=1.993 5, P<0.05). Conclusion:Concurrent car-cinomas were found in 15.3% of the total GIST cases. No special clinical symptoms were observed in most GIST cases with cancer complications, as revealed when the carcinomas were examined. The proliferative index of Ki-67 in the GIST cases with concurrent car-cinoma is significantly lower compared with that of the GIST cases without complications.

A 10 year-old female child developed erythema on the scalp,perioral area,neck,trunk,buttocks,palms and soles within 1 month after birth.Her skin was dry and rough,and the hairs were fine,soft,sparse and easily broken.As age advanced,typical hyperkeratosis and thickening of the skin occurred on an erythematous base.At the age of 5 years,the child developed photophobia and vision impairment.When the child was 8 years old,progressive hearing loss was observed.Physical examination revealed that the height and weight were 109 centimeters and 19 kilograms respectively.Skin examination showed fine,soft,sparse and easily-broken hair,large areas of brown plaques with crusts on the scalp,perioral area,neck,trunk and buttocks,and fissured,purulent and foul-smelling verrucous hyperplasia over these plaques.Brown to black hyperkeratotic plaques were scattered over the extremities,and diffuse hyperkeratosis occurred on the palms and soles.Both fingernails and toenails became thickened,cloudy and white with distal separation and deformation of the nail plate.As ophthalmic examination showed,the patient had photophobia,bilateral bulbar conjunctival hyperemia,corneal opacity and corneal vascular proliferation,and the visual acuity was 0.5 in the left eye and 0.2 in the right eye.Otolaryngological examination revealed moderate binaural sensorineural deafness.Stomatological examination showed enamel hypoplasia and diastema widening.Genetic testing showed a heterozygous mutation (c.C50T) in exon 2 of the gap junction protein beta 2 (GJB2) gene.Based on these clinical manifestations and examinations,the patient was diagnosed with keratitis,ichthyosis,and deafness (KID) syndrome.Skin lesions of the patient were significantly improved after the treatment with oral acitretin.

Objective To explore the mutation of Y-STR loci in meiotic allelic transmission in a large pedigree. Methods The oral swabs of 163 male individuals were collected froma L in pedigree. Twenty-two Y-STR genetic markers were typed with AGCUY 24 fluorescent detection kit (AGCUY 24 sys-tem), which also contained 16 Y-STR markers included in Y filerTmmultiple amplification kit (Y filer system). The genotyping results of Y-STR loci were compared between each two males in the pedigree. Results There were 20 and 30 kinds of haplotypes obtained with Y filer and AGCUY 24 systems in 163 male individuals fromthe L in pedigree, respectively. The rates referred to haplotype differences (RRHD) of these two typing systems between male pairs were 0.910 5 and 0.922 7, respectively. The average number of marker differences were 6.582 1 and 9.824 8, respectively. The RRHDincreased along with the incidents of meiosis. Conclusion Y-STR mutation leads to different Y-STR haplotypes among the male members in a paternal pedigree and the rate of difference increases along with the incidents of meiosis.

To investigate the profile of gene expression in Salvia miltiorrhiza and elucidate its functional gene, 454 GS FLX platform and Titanium regent were used to produce a substantial expressed sequence tags (ESTs) dataset from the root of S. miltiorrhiza. A total of 46 722 ESTs with an average read length of 414 bp were generated. 454 ESTs were combined with the S. miltiorrhiza ESTs from GenBank. These ESTs were assembled into 18 235 unigenes. Of these unigenes, 454 sequencing identified 13 980 novel unigenes. 73% of these unigenes (13 308) were annotated using BLAST searches (E-value < or = 1e-5) against the SwissProt, KEGG TAIR, Nr and Nt databases. Twenty-seven unigenes (encoding 15 enzymes) were found to be involved in tanshinones biosynthesis, and 29 unigenes (encoding 11 enzymes) involved in phenolic acids biosynthesis. Seventy putative genes were found to encode cytochromes P450 and 577 putative transcription factor genes. Data presented in this study will constitute an important resource for the scientific community that is interested in the molecular genetics and functional genomics of S. miltiorrhiza.

Objective To investigate the clinical pathologic significance of lymphangiogenesis in in colorectal cancer. Methods New lymphatic-specific markers D2-40 was used immunohistochemically to detect the lymphatic vessel density(LVD) in the intratumoural and peritumoral areas, and in normal tissue from 96 cases of colorectal cancer, which were analyzed with clinical pathologic parameters of those colorectal cancer. Results Significandy higher LVD was found in the intratumoural area(14.5±2.4), when compared with normal(5.9±1.1)and peritumoural areas(6.7±1.2) (P<0.01). LVD of the peritumoural area was higher than normal area (P< 0.01). However, peritumoural LVD was associated with both depth of invasion and liver metastasis (r=0.71,0.78 P<0.05), but not associated with tumour size, macroscopic type and lymph-node metastasis (P>0.05). Intratu-moural LVD was not correlated with tumour size, macroscopic type, the depth of invasion,lymph-node metastasis, and liver metastasis(P>0.05). Conclusion Lymphangiogenesis in the peritumoural area may be helpful in evalution of liver metastasis and prognosis.
