Objective To study the neuropathological changes of gastrin and substance P(SP) in the intermuscular and submucous nerve plexus of the colonic walls in patients with delayed motor constipation(DMC). Methods Gastrin and rabbit SP polyclonal antibiotics were used to make an immunohistochemical staining of the samples of different segments obtained from 10 patients with DMC and 8 normal subjects(control group) for a comparative observation as well as a relative semi-quantitative analysis. Results The immune positive nerve cells of gastrin and SP in the intermuscular nerve plexus of colon with DMC were markedly reduced; no differences in the immune response of gastrin and SP in the mucous nerve plexus were found between the two groups(P<0.01). With routine HE staining, focal inflammation occurred in the mucous membrane of DMC colon and that the neuronal vacuolus of the intermuscular nerve plexus degenerated, reduced and even disappeared. Conclusion The abnormal changes of the neural structure in the immune reponse of gastrin and SP in the intermuscular nerve plexus of colon with DMC might be related to reduction of gastrin and SP peptide neuron or dysfunctional.

Background and purpose:Lung cancer is the leading cause of morbidity and cancer-related mortality worldwide. A variety of driver genes were detected in lung cancer. Studies have shown that different gene mutations of lung cancer were found between different races. Most of Uyghurs live in Xinjiang, accompanied by a high morbidity of lung cancer. This study aimed to investigate the expression of driver genes in Uyghur patients with lung cancer in Xinjiang, China.Methods:This study collected the tissue specimens of 43 Uyghur patients with lung cancer, with a very different method to detectEGFR gene expression. real-time fluorescent quantitative polymerase chain reaction(RTFQ-PCR) was used to detectK-ras,ALK,ROS1, mutatedBRAF andPIK3CA gene expression. Analysis of the correlation between lung cancer gene mutations in Uyghur and clinical features of patients with lung cancer were performed.Results:Among 43 cases of specimens,EGFR mutation rate was 11.63%, while theEGFR gene mutation rates in adenocarcinoma and squamous cell carcinoma were 26.67% and 4.76%, respectively.EGFR gene mutation was not detected in large cell carcinoma, adenosquamous carcinoma and small cell lung cancer.EGFR gene mutation rate in patients with adenocarcinoma (26.67%) was signiifcantly higher than that in other types of lung cancer (3.57%). The difference was statistically signiifcant (P=0.024). There were 6 patients withK-ras12/13 heterozygous mutation, and the mutation detection rate was 16.28% (6/43). There were 2 patients withPIK3CA heterozygous mutation, and the mu-tation detection rate was 4.65% (2/43).EGFR andK-ras mutations occurred simultaneously in 1 case. No relationship was found betweenEGFR mutations and age, gender, smoking status, TNM staging, ECOG score among Uyghur lung cancer patients. This study did not ifnd mutation inALK,ROS1 fusion gene andBRAF gene among the 43 specimens. Conclusion:Compared with Asian populations, Xinjiang Uyghur patients with lung cancer have a lower rate ofEGFR mutations and a higher rate ofK-ras mutations, which is similar to the characteristics of European Caucasians.

Objective To investigate the efficacy of MSCs infused intravenously on the regeneration of injured spinal cord and rehabilitation of its neurological function. Methods 32 SD rats, male or female, weight about 300 g for each one. MSCs were separated, cultured and purified in vitro. Surface marker of MSCs, such as CD34, CD45, CD29 and CD90 were detected by flow cytometry. The rat spinal cord injury model was prepared according to the modified Allen method. After exposure of T10 spinal cord, the T10 segment of spinal cord was injuried by a 10 g weight falling down from 5 cm high place upon a round thin copper pad which was placed on the surface of T10 segment of spinal cord. The diameter of the copper pad is 3 mm. There are 24 rats in the injuried group and 8 in the non-injuried group. The injuried group was then divided into experiment group with 14 rats and control group with 10 rats at 24 hours after preparation of models. The rats in the injuried group and non-injuried group were infused with MSCs marked by Brdu through tail vein, and the rats in control group were infused with PBS. The neurological functions of rats were evaluated at 24 hours after injury and 1, 3, 5 weeks post-infusion respectively. At the same time, the immigration, survival and differentiation of MSCs were observed. Results The MSCs were uniformly CD29, CD90 positive and CD34, CD45 negative. In vivo experiment, transplanted MSCs survived and were localized to the injured spinal cord, and a few cells expressed NSE, MAP2 post transplantation 3 to 5 weeks. Significant improvement in functional outcome in rats treated with MSCs transplantation compared to control rats. The score of BBB in the treated group was higher than that in the control group (P
