Pharmacogenomics refers to all the genes encoding drug-metabolizing enzymes,drug transporters,and other drug targets. Studying the relations betweeen gene polymorphisms and drug effects as well as the prediction of adverse reactions at the gene level will be a new method for the clinical therapy of digestive system diseases. Therefore,pharmacogenomics will be a complement of traditional methods for forming and administering drugs regimens.

Objective To evaluate the operative technique and the short-term clinical results of ce-mentless total hip arthroplasty (THA) for developmental dysplasia of the hip (DDH) in adults with high level dislocation. Methods Nine patients (11 hips) with DDH of Hartofilakidis type Ⅲ, who underwent cement-less THA between 1997 and 2002, were analyzed. Of 9 patients, 8 were females, and 1 male with an average age of 29.4 years (range, 17 to 56 years). There were unilateral DDH in 7, and bilateral in 2. The patients had no previous surgery. The preoperative average length difference between the two legs was 4.1 cm (range, 0 to 7 cm). The femoral head was dislocated upward from the normal position by 4.8 cm on average (range, 3.2 to 7.0 cm). The Zweym?ller cup was placed on the original acetabulum in all patients with more than 80% bony coverage on the cup, and no bone graft needed. In 4 hips with more than 5 cm of displacement, the reduction of prosthesis was achieved by shortening osteotomy below lesser trochanter. The preoperative average Harris score was 40.2. Results All of 9 patients were obtained follow-up of X-ray films and clinical evaluation. The follow-up ranged from 6 to 32 months with a mean of 18.2 months, the osteotomy of 4 hips were bony healed at 3 months postoperatively showed by X-ray films. The postoperative average difference of the two leg length reduced to an average 1.1 cm (range, 0 to 3 cm), and the postoperative average Harris score increased to 90. Femoral nerve impairment occurred in 1 case, and recovered 4 months later. There were no loosening, dislocation and infection at follow-up. Conclusion Based on the short-term results of the cementless total hip arthroplasty for the developmental dislocation of the hip in adults with high level dislocation, it is proven to be a good technique, and the satisfied clinical results would be obtained.

Objective To investigate the effects of Berberine on growth of Immorto-Min colonic epithelial cell line (IMCE) and explore its possible mechanisms. Methods IMCE cells were treated with Berberine in the absence or presence of epidermal growth factor (EGF) and TNFα. Ki-67 staining and terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) assay were used to identify the cell proliferation and apoptosis respectively. Furthermore, Western blot analysis was performed to detect the epidermal growth factor receptor ( EGFR), protein kinase B (Akt) and their phosphorylation.Results ( 1 ) Proliferating activity of IMCE cells was increased after adding EGF and the proportion of cell proliferation was ( 10. 64 ± 1.41 ) %. The proportion was significantly lowed in EGF plus Berberine group [(1.81 ±0. 85)%] compared to the EGF group(P ＜0. 01 ), while the lowest was the Berberine group [(0.49 ± 0.42) %]. (2) The proportions of cell apoptosis were ( 8.47 ± 2. 52 ) % and (9. 39 ± 2. 13 ) %in the Berberine group and TNFt group respectively which were significantly higher compared to the normal control [(0. 27 ± 0. 30)%], both P ＜ 0. 01. (3) The phosphorylation of EGFR was significantly increased after adding EGF and p-EGFR was decreased in EGF plus Berberine group at a concentration-dependent manner. (4) Moreover, the phosphorylation of Akt was enhanced after addition of TNFα , while the phosphorylation in the TNFα and Berberine group was inhibited compared to the TNFα group. Conclusions Berberine may suppress the proliferation and promote the apoptosis of IMCE cells. The mechanisms may relate to the inhibition of the phosphorylation of EGFR and Akt.

Objective To analyze the clinical and pathological features of upper gastrointestinal serrated lesions.Methods A total of 21 patients with upper gastrointestinal serrated lesions in Tianjin Medical University General Hospital between January 2011 and December 2015 were retrospective analyzed.Data of the patients including demographics, clinical and pathological features were collected.Among the 21 patients, 18 patients, who underwent colonoscopy simultaneously or within six months, were selected as the study group, each patient was compared to 4 randomly selected controls without serrated lesions, who also underwent colonoscopy within the same time period.Differences of colorectal neoplasia detection were analyzed between the cases and controls.Results The mean age of 21 patients was 55.3±17.2 years, and 11 cases were male.Involving the locations of serrated lesions, 17 cases were found in the stomach (including 3 in the cardia, 9 in the corpus, and 5 in the antrum), and followed by 3 in the duodenum and 1 in lower esophagus.The mucosa pathological morphology showed that 6 cases were serrated hyperplasia, 8 cases were hyperplastic polyps, 6 cases were serrated adenomas with low grade dysplasia and 1 case was in the duodenum intramucosal carcinoma.Seven (38.9%) colorectal adenomas were found in the study group, including 3 (16.7%) non-advanced colorectal adenomas and 4 (22.2%) advanced colorectal adenomas.Eight (11.1%) colorectal adenomas were found in the control group, including 5 (6.9%) non-advanced colorectal adenomas and 3 (4.2%) advanced colorectal adenomas.The rate of colorectal adenoma detection in the study group was significantly higher than that in the control group (38.9% VS 11.1%, P=0.010, OR=5.091, 95%CI:1.534-16.890).Conclusion Upper gastrointestinal serrated lesions can be found in various mucosal lesions with different pathological morphologies.Moreover colonoscopy is likely to be recommended to detect concurrent colorectal adenoma for these patients.

Objective To assess the results of colonoscopy surveillance in 5 years after polypectomy of non-advanced colorectal adenoma and to identify its risk factors. Methods Patients undergoing colonosco-py and followed up with colonoscopy within 5 years between January 2003 and December 2013 were retro-spectively analyzed.No substance or only small quantity of clear water left in the intestinal tract and colono-scopes accessing ileocecus were regarded as complete examination. The initial colonoscopy was regarded as the baseline colonoscopy. Patients with non-advanced adenomas were assigned to the case group and those without were to the control group. Data of clinical characteristics and colorectal findings were estimated and risk factors were identified. Results A total of 828 patients were included,374 patients in the case group and 454 in the control group on baseline colonoscopy.The case group had a low incidence of advanced adeno-mas at a 1 to 5 years interval when compared with the control group,both with adequate baseline examination [1. 5%(5/ 326)VS 2. 2%(9/ 408),P = 0. 51]. The detection rates of advanced adenomas on follow-up colonoscopy at 1 to 3 years and 3 to 5 years in case group were 1. 7%(3/ 178)and 1. 4%(2/ 148),respec-tively(P>0. 05).Regression analysis showed age≥50 years old and being male were the independent risk factors for advanced adenomas recurrence within 5 years follow-up. No colon cancer was found in 828 patients during the follow-up. Conclusion Surveillance colonoscopy intervals within 5 years is of little benefit to pa-tients who had adequate polypectomy. Too early reexaminations due to concerns about advanced adenomas recurrence can be avoided.

Cystic echinococcosis is one of the most widespread and severe zoonotic helminthic diseases .To understand the phylogeny and genetic polymorphism Echinococcus granulosus (E .granulosus) prevailed in south region of Qinghai Prov-ince ,partial fragment of cytochrome oxidase Ⅰ (COX Ⅰ ) gene sequences were used to infer the phylogenetic relationship of 59 collected samples of E .granulosus in Qinghai Province .Total 72 sequences (13 sequences from GenBank) were aligned using CLUSTAL X ,and then ,Bayesian analyses were performed in Mrbayes-3 .1 .2 .The results revealed that Echinococcus spp .isolates did not form a monophyletic group .The most samples clustered with E . granulosus strain (G1) (AB297617) , but showed high genetic polymorphism .Another three samples clustered with E .multilocularis (AB018440) ,while they showed complex phylogenetic relationships among them ,further indicating that Echinococcus spp .isolates from Qinghai Prov-ince may has a more complex evolutionary history than expected .

[Abstract ] Objective Cofilin-1 is involved in the pathogenesis of various tumours .However, the expression and effect of Cofilin-1 in hepatocellular carcinoma is not clear .The aim of this study is to observe the Cofilin-1 gene expression in human hepatocel-lular carcinoma (HCC) tissues, and to explore the effect of Cofilin-1 gene expression on invasion and metastasis of HCC HuH-7 cells. Methods Real-time quantitative PCR was used to assess the Cofilin-1 gene expression in human HCC tissues and normal tumor-ad-jacent tissues.The specific small interfering RNA ( siRNA) of Cofilin-1 sequence was synthetized in vitro , and was transfected into HCC HuH-7 cells using liposome transfection.The experiment was divided into Cofilin-1-siRNA group, Ctrl-siRNA group and un-transfected group.Western blot assay was used to detect the protein expression of Cofilin-1.Migration and invasion experiments in vitro were used to investigate the invasive ability of transfected cells. Results Compared with the adjacent liver tissue , Cofilin-1 gene ex-pression in human liver cancer tissue was significantly increased (0.698 ±0.156 vs 3.523 ±0.412, P<0.05).The expression of Cofilin-1 protein in Cofilin-1-siRNA group was 0.558 ±0.033, which was lower than that in Ctrl-siRNA group ( 0.933 ±0.015 )
and in untransfected group (0.961 ±0.020) (P<0.05).The results of migration and invasion experiments in vitro showed that the amount of migration and invasion cells in Cofilin-1-siRNA group were significantly lower than Ctrl-siRNA group or untransfected group (58.50 ±1.78 vs 79.00 ±1.33, 74.50 ±1.35,P<0.05; 36.50 ±0.83 vs 60.20 ±1.60, 51.50 ±1.14, P<0.05). Conclusion Cofilin-1 is highly expressed in HCC, and the invasion and metastasis of HCC HuH-7 cells is suppressed by inhibiting the Cofilin-1 gene expression.
