OBJECTIVEThis study was aimed at evaluating and comparing the quality of life in patients who underwent laparoscopic and open cholecystectomy for chronic cholecystolithiasis.

METHODSThe study included 25 patients with laparoscopic cholecystectomy (LC group) and 26 with open cholecystectomy (OC group). The quality of life was measured with the Gastrointestinal Quality of Life Index (GLQI) preoperatively, thereafter regularly at 2, 5, 10 and 16 weeks after the operation.

RESULTSThe mean preoperative overall GLQI scores were 112.5 and 110.3 in LC and OC group respectively (P>0.05). In the LC group, the mean overall GLQI score reduced slightly to 110.0 two weeks after the operation (P>0.05). The LC group showed significant improvement in overall score and in the aspects of symptomatology, emotional and physiological status from 5 to 16 weeks postoperatively. In the OC group, the GLQI score reduced to 102.0 two weeks after surgery (P<0.05). Significant reductions were shown in the aspects of symptomatology, physiological and social status. The GLQI scores returned to the preoperative level of 115.6 ten weeks after the operation (P>0.05). The patients experienced significant improvements of GLQI sixteen weeks after OC operation (P<0.01~0.05). Within the 10 postoperative weeks, the LC group had significantly higher GLQI scores than the OC group (P<0.05).

CONCLUSIONSLC can improve the quality of life postoperatively better and more rapidly than OC. The assessment of quality of life assessment is a valid method for measuring the effects of surgical treatment.

OBJECTIVETo observe the clinicopathological characteristics of gastric stump cancer (GSC) and evaluate the benefits of radical surgery of GSC.

METHODSThe clinicopathological characteristics and postoperative survival time of 37 GSC patients who underwent surgery were investigated retrospectively. The survival time was compared according to the type of surgical operation (radical resection vs palliative operation). Twenty-one cases that received radical resection were analyzed based on the pTMN stage. Survival curves were traced by using Kaplan-Meier methods.

RESULTSMost GSC (32/37) was detected in patients who had received Billroth II reconstruction after partial gastrectomy for benign gastric disease. The lesser curvature side and the suture line of anastomosis were the most frequent sites where GSC occurred (27/37). Differentiated adenocarcinoma was the dominant histopathological type (24/37). The postoperative 5-year survival rate of early stage GSC patients (n=9) was significantly higher than advanced stage GSC (n=12) (55.6% vs 16.5%, xL2=11.48, P<0.01). Five-year survival rate of 21 GSC patients with radical resection were 75% (3/4) for stage I, 60% (3/5) for stage II, 14.2% (1/7) for stage III, and 0% (0/5) for stage IV respectively. The median survival time of 21 GSC patients who underwent radical resection was longer than those undergoing palliative operation (43.0 m vs 13.0 m, x L2=36.31, P<0.01), the median survival time of stage IV patients with radical resection was 23.8 months.

CONCLUSIONSWithout remote metastasis, radical resection for GSC is possible, and is an effective way to improve the prognosis of GSC. Even in stage IV GSC, radical resection can still prolong the survival time. It is necessary for the patients with benign gastric diseases who received partial gastrectomy to carry out the endoscopy follow-up, especially in patients with Billroth II reconstruction procedure at 15-20 years.

Objective:To compare gene expression profiles in normal human cervical epithelial cells (HcerEpic) before and after Chlamydia trachomatis ( Ct) infection. Methods:HcerEpic cells that were pretreated with DEAE-D were infected with Ct serotype E standard strain and then cultured for 44 h. Uninfected HcerEpic cells were used as the control group. Total RNA was extracted from the cells in each group and reverse transcribed to construct a cDNA library. Differences in gene expression profiles between the two groups were analyzed by high-throughput sequencing and the representative genes were selected for verification by qPCR. Results:A total of 23 997 genes were detected, including 125 differentially expressed genes. Among the 125 genes, 119 were up-regulated and six were down-regulated. GO analysis showed that the differentially expressed genes were enriched in several biological processes including defense response to virus, typeⅠinterferon signaling pathway and cellular responses to typeⅠinterferons. KEGG enrichment analysis showed the differentially expressed genes were mainly enriched in the pathways related to virus infections, such as influenza A virus, herpes simplex virus, EB virus and HPV, and NOD-like receptor pathway.Conclusions:There were significant differences in transcriptome profiles of HcerEpic cells before and after Ct infection. The differentially expressed genes were mainly enriched in the interferon pathway, which was closely related to the antiviral processes in cells. qPCR verified the differentially expressed genes and the genes closely related to the interferon pathway, such as ISG15, IFIT2, OASL and UBE2L6.
