1.Cytokeratin 14 and cancer
Journal of International Oncology 2015;(6):436-438
Cytokeratin 1 4 (CK1 4)has a different degree of expression in NSCLC,breast cancer,cer-vical cancer,esophageal cancer and other tumors,except in the normal basal cells.CK1 4 is mainly expressed in the peripheral part of the tumor,which is rarely expressed in the non-aggressive part.Usually the higher malignant of the tumor has the more expression of CK1 4.Given all that,CK1 4 gene plays an important role in the tumor progression and metastasis in a variety of tumors,which can be considered as an biomarker being used in the diagnosis,treatment and prognosis evaluation.

Objective Uncemented prothesis has become the preference of first hip arthroplasty, but there is a little study on its application in cemented acetabular revision arthroplasty.This paper aimed to evaluate the clinical effects of uncemented acetabular cup in cemented acetabular prosthesis revision arthroplasty. Methods A retrospective analysis was made on the clinical data of 31 patients(31 hips) who underwent revision arthroplasty using uncemented acetabular prosthesis from January 2012 to March 2015.Har-ris hip score( HSS) was applied to measure the hip function and visual analogue score( VAS) was preformed to assess the pain degree of knee joint preoperatively and postoperatively(3 months, 6 months and 1 year).All the patients were followed up for a mean of 22 months ranging from 3 to 42 months. Result The mean HSS increased from preoperative points (53.19 ±9.12) to postoperative points([77.71 ±5.75]at 3 months,[80.61 ±5.74] at 6 months,[82.94 ±5.80] at 1 year ).The mean VAS score decreased from preoperativepoints (6.23 ±1.23) to postoperative points(0.26 ±0.27).No lossening, infection or deep vein thrombosis were found in the patients′prostheses. Conclusion For patients with PaproskyI-Ⅱ acetabular defects, uncemented acetabular prosthesis has satisfactory short-term clinical results in revision arthroplasty with cemented acetabular prosthesis, however, long-term clinical results remain to be further observed.

Objective To investigate the effect of GnRH-A in gastric cavity on function of gastrin clls in digestive tract of rats. Methods The immunohistochemical ABC method and enzyme-link immunoassay were used in the experiment. Results The densities of the gastrin immunoreactivity cells in the stomach and small instestin of the experiment groups were 19.60?3.63 and 18.00?2.31 respectively, those in stomach was 10.30?2.41 while in small intestin was 9.00?2.05 of control groups respectively (P

Objective To study the distribution and sequence analysis of gonadotropin releasing hormone (GnRH) gene in cultured gastric parietal cells of rats. Methods The distribution of GnRH molecule and GnRH mRNA were observed out through immunohistochemical ABC methods and in situ hybridization methods in cultured gastric parietal cells of rats. After isolation of the total RNA from the parietal cells, RT PCR was conducted to obtain GnRH cDNA. Then, the products of PCR was purified, digested by the restriction enzyme of Hind Ⅲ and EcoR Ⅰ, and DNA fragments interests were cloned into pUC19 vector. The products of PCR were analyzed by sequenceing with Sanger's method after identified by PCR and digestion of restriction enzyme. Results Gastric parietal cells showed GnRH immunoreactivity, positive material was located in cytoplasm with negative nuclei. GnRH mRNA hybridized signals were also detected in cytoplasm with negative nuclei. The specific amplified band of GnRH mRNA was detected through agarose gel electrophoresis and gene sequence is identical to the GnRH which has been reported in rat hypothalamus.Conclusion Our data suggest that GnRH could be produced by gastric parietal cells of rats and may modulate physiological function of gastric parietal cells of rats.\;[

This study was aimed to provide a reference for the development, registration, and clinical use of hospital traditional Chinese medicine (TCM) preparations, in order to analyze and assess their safety and risk. It also provided a reference for the technical review and supervision of hospital TCM preparations. Through collecting review materials of hospital TCM preparations from 2012 to 2014 in the Sichuan Food and Drug Administration, 21 preparations developed by clinical experiences were screened out. Analysis was made on their ingredients, preparation process and acute toxicity data. The results showed that 98 kinds of Chinese herbal medicines were contained in 21 preparations. The dosages of herbs were in compliance with theChina Pharmacopoeia2010 Edition. Preparation processes of 16 preparations were made by water extraction, grinding and other traditional techniques. The preparation processes of the remaining 5 preparations were involved with alcohol extraction or alcohol precipitation. Acute toxicity test data were obtained with experimental data in mice. Clinical usages of preparation were much lower than MTD or LD50. It was concluded that these hospital TCM preparations developed by clinical experiences were with high safety.

Objective To study the effects of DHPs calcium antagonist Mn9202 and lacidipine on 5-HT、TH and 5-HTR of rat stomach fundus smooth muscle cells. Methods It's effects was investigated by using immunocytochemistry and image analysis of stom- ach fundus smooth muscle cells in culture and compared with cyprohetadine(antagonist of 5-HT). Results 5-HT、TH and 5-HTR im- munoreactive substances were existed in SFSMC. The results of image analysis indicated that the content of 5-HT. TH and 5-HTR were significantly lower when using Mn9202.lacidipine and cyprohetadine. Conclusion The results suggest that the rat stomach fundus smooth muscle cells possess 5-HT autocrine function, and DHPs calcium antagonist reduce the number of 5-HT receptor in the rat stomach fundus smooth muscle cells though the reduction of 5-HT sythesis, this results conform with cyprohetadine (antagonist of 5 - HT).
