Role and prognostic impact of E-cadherin expression on invasion and metastasis of gastric carcino-ma

Journal of Clinical Surgery.2014;(5):347-350. doi:10.3969/j.issn.1005-6483.2014.05.017

Objective To investigate the role and prognostic impact of E-cadherin( E-cad)on in-vasion and metastasis of gastric carcinoma by analyzing E-cadherin expression at DNA,RNA and protein levels. Methods RNA and protein expression of E-cad were tested in 60 cases of gastric carcinoma and adjacent tissues by streptavidin peroxidase( SP )immunohistochemistry and in situ hybridization. DNA methylation of E-cad was tested with methylation-specific polymerase chain reaction( MSP). Results The positive rates of E-cadherin protein and mRNA in gastric carcinoma were significantly lower than those in adjacent tissues. DNA methylation of E-cad negatively correlated with the E-cad protein and RNA expres-sion in gastric carcinoma respectively(r= -0. 355,r = -0. 271). DNA methylation of E-cad negatively correlated with the 5-year survival rate of gastric carcinoma(r = -0. 381,P ﹤0. 01). However,E-cad protein positively correlated with the 5-year survival rate of gastric carcinoma(r=0. 378,P﹤0. 01). Con-clusion The decreased expression of E-cad is one of the most important biological features in gastric car-cinoma. Methylation of E-cad DNA may be an important agent causing low expression of E-cad protein and mRNA and it can be used as an important indicator in predicting invasion and metastasis of gastric cancer.

Yongdong ZHANG ; Zhiming QIAO ; Weifeng QIAN

Journal of Clinical Surgery.2014;(9):653-655. doi:10.3969/j.issn.1005-6483.2014.09.012

Objective To evaluate the causes,prevention and treatment of mesh infection after abdominal wall hernia mesh repair.Methods The clinical data of 14 mesh infections admitted from De-cember 1997 to December 2013 were analyzed retrospectively.There were one case of inguinal hernia with Lichtenstein repair,eleven cases of inguinal hernia with preperitoneal repair,one case of incisional hernia with Bard Composix Mesh and 1 case of parastomal hernia with mesh repair above the abdominal muscle. Based on prothetic materials and infection status,the infection meshes were removed in 4 cases and open dressing change were operated in 10 cases.Results All patients were healed and discharged without peri-operative death.There was no hemorrhage and bladder injury during the procedures.The time of dressing change ranged from 3 weeks to 6 months,with a median of 4 weeks.All patients were followed up for 8 to 64 months.One patient had a recurrence of abdominal incisional hernia.Conclusion There are many fac-tors related to mesh infection after mesh repair and preventing mesh infection is the most important.Once the infection occurs,the management should be individualized.Antibiotic treatment and surgical drainage can be effective in most polypropylene mesh(PPM)infection However,infected expanded polytetrafluoro-ethylene(ePTFE)mesh should be removed completely.

Jiapu XU

Journal of Clinical Surgery.2014;(9):650-652. doi:10.3969/j.issn.1005-6483.2014.09.011

Objective To analyze the reasons and notes of failed laparoscopic surgery for patients with inguinal hernia.Methods The clinical data of 17 cases of failed laparoscopic inguinal hernia opera-tion from August 2003 to January 2013 in our hospital were reviewed retrospectively.Results The reasons of reoperation included 9 cases of recurrence,1 case of patch infection,1 case of intestinal fistula,1 case of intestinal wall hernia,2 cases of suture reaction,1 case of bladder injury,1 case of ruptured umbilical inci-sion,1 case of scrotal hematoma and 1 cases of iliac vascular injury.Six patients received repeated laparo-scopic surgery and the other patients were treated with open surgery.All patients were successfully treated and discharged after 2-15 days.Conclusion When the laparoscopic technique is applied for inguinal her-nia,indications of laparoscopic surgery should be strictly controlled and operation standard should be fol-lowed.For patients with special condition,difficult laparoscopic operation should be timely converted to laparotomy.Close attention needs to be paid to the occurrence of postoperative complications and they need timely treatment.

Journal of Clinical Surgery.2014;(9):682-684. doi:10.3969/j.issn.1005-6483.2014.09.022

Objective To explore the values and relationship among the contents of thrombus precursor protein(TpP)and plasma D-dimer(D-D),complications after mechanical heart valve replace-ment and their correlation with international normalized ratio(INR)in anticoagulation therapy and monito-ring.Methods A total of 150 patients with mechanical heart valve replacement were enrolled.TpP,D-D, INR,other indicators and complications were compared to draw conclusions.Results There were signifi-cant differences in TpP among the groups(P<0.0083).Significant differences in D-D among the postop-erative group(100.96 ±61.56),thrombosis group(17.78 ±5.94)and control group(5.97 ±1.58)were observed(P<0.0083).Significant differences in INR among the postoperative group(1.65 ±0.34),hem-orrhage group(2.22 ±0.65)and control group(1.11 ±0.10)were observed(P<0.0083),but the effec-tiveness of INR monitoring for determining the state of thrombosis was limited to a certain extent.Conclu-sion TpP and D-D examination can facilitate monitoring after mechanical heart valve replacement,and it has a certain guiding significance for determining anticoagulation therapy and monitoring of complications after mechanical heart valve replacement.

Yumin LI

Journal of Clinical Surgery.2014;(9):669-672. doi:10.3969/j.issn.1005-6483.2014.09.018

Objective To explore the effects of anatomical and nonanatomical hepatectomy on the prognosis of patients with hepatocellular carcinoma(HCC).Methods A total of 62 HCC patients were enrolled,including 33 cases of anatomical hepatectomy(Group AH)and 29 cases of nonanatomical hepa-tectomy(Group IH).The operation situation and hematocrystallin(HB)loss were record.Fasting venous blood of HCC patients were extracted for detection of circulating AFP mRNA expression.The recurrence, mortality and complication rate were recorded at the same time.Results The operative time of Group AH was significantly higher than that of Group IH,while the bleeding volume and HB loss were lower(P<0.05).There were no significant differences in AFP mRNA expression and recurrence rate.The short-term mortality rate of Group AH was lower than Group IH(P<0.05 ),but their long-term mortality rates were similar(P>0.05 ).There was no significant difference in complication rate between groups.Patients of Group AH got more hepatosis due to liver cirrhosis or fibrosis,while patients of Group IH got more bleeding or infection due to the central tumor.Conclusion Anatomical hepatectomy has advantages in protecting artery and improving prognosis for HCC patients,but it has surgical risks for patients with serious patholog-ical damage in hepatic lobes,and nonanatomical hepatectomy may be considered.

Liping OUYANG ; Jianguo LI

Journal of Clinical Surgery.2014;(12):895-898. doi:10.3969/j.issn.1005-6483.2014.12.007

Objective To evaluate the effects and security of single or combined sufentanil application on sedation and analgesia for mechanically ventilated patients in intensive care unit(ICU).Method A total of 160 ICU patients with mechanical ventilation were randomly allocated into four groups:sufentanil group,sufentanil plus midazolam group,sufentanil plus dexmedetomidine group and fentanyl group.Facial pain scale(FPS),Ramsay score and vital signs were employed to assess the effects of different therapies on organ functions and adverse reactions.Result After the treatment,FPS in all groups were significantly decreased and maintained around 3 points.Ramsay scores were significantly increased(P <0.001)and the score in group given sufentanil combined with midazolam or dexmedetomidine at the time points of30 min,1 h,6 h were even higher.Compared with the preoperative data,indicators of lung function(PaCO2and blood lactic acid),liver function(AST)and renal function(Cr)were decreased in all groups(P <0.05).Respiratory rate in the fentanyl group was significantly higher than the others.Total consumption ofsufentanil in group with combined sufentanil application was significantly lower.No significant differencesin adverse reactions were noticed among the groups(P >0.05).Conclusion For mechanically ventilatedpatients,sufentanil has efficient sedative and analgesic effects with less physiological interference and severe adverse reactions.Combined application is beneficial in decreasing total sufentanil consumption andinhibition to respiratory system,which is worthy of being spread.
