ABSTRACT
Objective@#To investigate the association between the promoter region-938 polymorphism of B-cell lymphoma/leukemia-2 (Bcl-2) gene and the esophageal cancer (EC) and gastric cardia adenocarcinoma (GCA) in Hebei Province. @*Methods@#From 2007 to 2010, 145 esophageal cancer patients and 169 cardiaccancer patientsfrom the outpatient department of the Fourth Hospital of Hebei Medical Universitywereselected in a case group, and 195 non-tumor patients were selected in a control group during the same period. A questionnaire survey was used to collect information of research subjects. Pathological tissues were collected to extract genomic DNA and detect the genotype of bcl-2 gene -938. A multivariate logistic regression model was used to analyze the association between the bcl-2 gene locus 938 CC genotype and the EC and GCA. The interaction between age, gender, smoking, drinking, upper gastrointestinal family history and the bcl-2 gene locus 938 CC genotype was analyzed by likelihood ratio test. @*Results@#The age of the esophageal and cardiac cancer groups was (56.3±8.3) and (57.1±8.4) years old, and that of the control group was (54.7±7.1) years old. The proportion of the bcl-2 gene locus 938 CC genotype in the esophageal group [48.3% (70/145)] and the cardiac cancer group [48.5% (82/169)] was higher than that in the control group [33.8% (66/195)] (both P values<0.05).Compared with the AA genotype, the risk of esophageal cancer and cardiac cancerin people with the CC genotype was 2.386 (1.20-4.76) and 2.564 (1.27-5.18) respectively. In the population with CC genotype, compared with the positive family history, drinking, and male, the negative family history, non-drinking, and female had a higher risk of esophageal cancer; compared with the non-smoking, negative family history, non-drinking and male, the smoking, positive family history, drinking, and female had a higher risk of cardiac cancer (all the P interaction values were <0.05). @*Conclusion@#People with bcl-2 gene locus 938 CC genotype in Hebei Provincewere more likely to suffer from the esophageal and gastric cardia adenocarcinoma.
ABSTRACT
Objective To conduct the in vitro study on the changes of gene and biological characteristics of different esophageal interstitial fibroblasts after their indirect contact wish esophageal cancer cell lines.Methods The mRNA levels of Vimentin,α-SMA,TGF-β1,HGF,MMP2 and MMP9 in normal esophageal interstitial fibroblasts(NFs),atypical hyperplasia interstitial fibroblasts(AFs) and cancer related fibroblasts(CAFs) and PCNA mRNA in esophageal carcinoma cell line were detected after their indirectly mutual contact.The invasion test of carcinoma cell line was conducted.Results From NFs,AFs to CAFs,the expression of Vimentin mRNA had no difference.The mRNA expressions of α-SMA,TGF-β1,HGF,MMP2 and MMP9 were gradually increased.After indirectly mutual contact with esophageal carcinoma cell line,the mRNA expressions of α-SMA,TGF-β1,HGF,MMP2 and MMP9 in NFs and AFs were up-regulated,and the difference was statistically significant(P＜0.05),while the related mRNA expression in CAFs had no obvious change.The expression of PCNA mRNA in esophageal carcinoma cell line had no change after contact with NFs,but the expression of PCNA mRNA was significantly up-regulated after interaction with AFs contacting with CAFs.Conclusion The esophageal carcinoma cells and esophageal interstitial fibroblasts could affect the proliferation activity and invasive characteristics of counterparts.
ABSTRACT
Objective To discuss the effect of the appointment checkup process optimized with the theory of constraints in shortening the appointment waiting time. Methods The patients who underwent ultrasonography, magnetic resonance imaging examination, and CT examinations were selected from the First Hospital of Shanxi Medical University from March 2017 to February 2018. Firstly, we applied the theory of constraints to investigate and analyze the status of medical technology examinations. Secondly, we optimized the process according to the results of the investigation. Finally, we compared the appointment duration of medical examinations before and after the optimization. Results Thanks to support of departments involved, the longest ultrasonography appointment waiting time was reduced from 3. 74 days to 1. 32 days. The longest appointment time for magnetic resonance imaging examination was reduced from 3. 74 days to 1. 33 days. The longest appointment waiting time for CT was reduced from 2. 62 days to 1. 55 days, and the goal of completing the checkup the day after the prescription was reached in the continuous improvement phase. Conclusions The optimization of the medical technology examination appointment process based on the constraint theory can effectively shorten the checkup appointment duration, maximize utilization of medical resources and optimize the services.
ABSTRACT
Objective To assess the safety and effectiveness of laparoscopic implantation of three-dimensional (3D)-printed extravascular stent for treatment of nutcracker syndrome (NCS).Methods The clinical data of NCS in our hospital were prospectively collected from August 2015 to August 2016.Doppler ultrasound and CT examination were performed before the operation of all the patients who were in line with the diagnostic criteria of NCS.The 3D model of extravascular stents with especial device to prevent migration was designed and was made by 3D metal printer with titanium alloy.The left renal vein(LRV) was exposed completely up to the inferior vena cava,then the stent was placed around the compressed LRV.Results 10 patients were enrolled in the study,including 9 males and 1 females,age (21.5 ±4.6) years.Among these patients,there were 4 cases with severe hematuria,1 case with proteinuria,5 cases with left lumbago,and 5 cases with left severe varicocele.The preoperative doppler ultrasound examination showed the diameter of the the compressed LRV was (1.57 ± 0.25) mm,and flow velocity was (164.40 ± 55.27) cm/s;the diameter of the LRV at the renal hilum was (8.7 ± 1.59) mm,and flow velocity was (10.70 ± 2.21) cm/s.The average operation time was (75 ± 11) min,and the average hospital stay after operation was 7 d.All symptoms were relieved at 3-7 d after operation.All patients were asymptomatic and all stents were stable after follow-up.At 12 months after surgery,the diameter of the LRV at the renal hilum was (8.23 ± 1.90) mm on doppler ultrasound,and there was significant decrease (P ＜ 0.01);the flow velocity was (21.20 ±3.88) cm/s,and there was significant increase (P ＜ 0.01).Conclusions Laparoscopic three-dimensional printed extravascular stent placement is a safe,effective and minimally invasive technique for treatment of NCS.

ABSTRACT
Objective To explore the characteristics of selective attention function in patients with silent cerebral in-farction (SCI) and depression, the relationship between depression, selective attention and cognitive dysfunction. Methods Eighty-two patients with SCI and 82 normal subjects were selected and evaluated by using Hamilton Depression Rating Scale (HAMD), Montreal cognitive assessment (MoCA) and Stroop color-word test (CWT). Patients with SCI were further classified into depression subgroup and no-depression subgroup based on the score of HAMD. Results The score of MoCA was lower in SCI group (23.11 ± 5.41) and was much lower in depression subgroup (20.31 ± 5.44) compared with control group (28.70 ± 2.18) (all P<0.01). Compared with control group, the reaction times of card A, B, C and Stroop interference effects (SIE) were prolonged in SCI group. The reaction time of card A, B, C and SIE were (33.25±14.10);(42.45±15.18);(104.68 ± 25.08) and (62.24 ± 21.53) in depression subgroup, respectively. The error counts of card B, C and SIE were in-creased (P<0.05) in SCI group. The error counts of card B,C and SIE were (3.59±2.14), (15.67±7.20) and (12.08±6.46) in depression subgroup, respectively. The scores of MoCA were negatively correlated with the reaction time and error counts of SIE (r=-0.429,r=-0.500,all P<0.01).The location of infarction was correlated with the score of HAMD and error counts of SIE to some degree: both of the scores were higher in patients with left infarction compared with right infarction and were higher in patients with cortex infarction compared with subcortex infarction. Conclusion The present study revealed that patients with SCI and depression have selective attention deficit which is closely correlated with the level of cognitive function.
