OBJECTIVETo explore the application of mesoesophagus suspension technique to improve the upper mediastinal lymph node dissection during thoracoscopic esophagectomy in the treatment of esophageal cancer.

METHODSClinical data of 164 thoracic esophageal cancer patients who underwent combined thoracoscopic and laparoscopic esophagectomy with two-field lymph node dissection in the Union Hospital of Fujian Medical University between October 2012 and June 2015 were retrospectively analyzed. Among 164 patients, 80 cases underwent upper mediastinal lymph node dissection by traditional method (traditional group), and the remaining 84 cases underwent upper mediastinal lymph node dissection by mesoesophagus suspension technique (suspension group). The operation time, estimated blood loss, number of excised lymph nodes and postoperative complications were compared between the two groups.

RESULTSThere were no significant differences in gender, age, location of tumor and pathology stage between the two groups. The operation time in the two groups was similar. The suspension group had significantly less thoracic blood loss than traditional group [(85±5) ml vs.(140±7) ml, P=0.000]. The number of dissected lymph nodes of bilateral recurrent laryngeal nerve was more in suspension group [median (interquartile range): left: 3 (2 to 4) vs. 2 (1 to 3), P=0.013; right: 3(2 to 6) vs. 2(1 to 3), P=0.007]. There was no significant difference in metastatic rate of lymph node in different sites between the two groups. The highest metastatic rate of suspension and traditional group was found at paracardia lymph nodes[22.6%(19/84) and 22.5%(18/80)], the next was at right laryngeal nerve lymph nodes [17.9%(15/84) and 15.0%(12/80)] and left laryngeal nerve lymph nodes [16.7%(14/84) and 12.5%(10/80)]. There were no significant differences with regard to the incidence of major postoperative complications between two groups, including respiratory complication, anastomotic leakage, vocal cord palsy.

CONCLUSIONSUpper mediastinal bilateral recurrent laryngeal nerve lymph node is the predilection site of lymphatic metastasis of thoracic esophageal cancer. Application of mesoesophagus suspension technique in thoracoscopic esophagectomy can improve the clearance quality of bilateral recurrent laryngeal nerve lymph nodes.

OBJECTIVE: To study the change of endogenous hydrogen sulfide (hydrogen sulfide, H2S) and its rate-limiting enzyme Cystathionine-gamma-lyase (CSE) in allergic rhinitis through guinea pigs with intervention treatment. METHOD: Twenty-four guinea pigs were divide into 4 groups at random, one group were models of allergic rhinitis (AR) which were established by using ovalbumin, the second group were treated with NaHS after sensitized, the third group were treated with Propargylglycine (PPG) which was suppression of CSE after sensitized, and the last group were treated with saline for control. The concentration of eotaxin of nasal lavage and H2S in plasma were recorded, and then the expression of CSE in nasal mucosa was determined by real-time fluorescence RT-PCR. RESULT: The concentration of eotaxin in nasal lavage of sensitized group were higher than those of control (P < 0.01), and concentration of H2S in plasma and expression of CSE in nasal mucosa were lower than control (P < 0.05). The concentration of eotaxin decreased when treated with NaHS and increased when treated with PGG (P < 0.05). Level of H2S in plasma and expression of CSE increased when treated with NaHS and decreased when treated with PGG (P < 0.05), and the level of H2S was positive linear correlate with the expression of CSE. CONCLUSION Endogenous H2S perhaps plays a significant role in the pathogenesis of allergic rhinitis, and it was mainly regulated by CSE.

Objective: To investigate the expression of CARD10 in hepatocellular carcinoma (HCC) tissues, and the roles of CARD10 in HCC progression especially apoptosis inhibition. Methods: The expression of CARD10 was examined in pared non-tumor liver tissues and HCC tissues using qRT-PCR, and their correlation with HCC TNM stage was analyzed using Spearman’s rank correlation assay in SPSS 17.0. In HCC cells with CARD10 overexpression or knockdown, cytometry using Annexin-V/PI labeling was used to measure apoptosis, and Western blotting was used to determine the activation of NF-κB pathway. Results: CARD10 expression was significantly increased in HCC tissues as compared to that in pared non-tumor liver tissues (P<0.01), and the increased CARD10 in HCC was positively correlated with TNM staging (P<0.01). The apoptosis of HCC cell lines SMMC-7721 and BEL-7402 was inhibited by CARD10 overexpression while promoted by CARD10 knockdown, and the pro-survival NF-κB pathway was also enhanced by CARD 10 over-expression while suppressed by CARD10 knockdown. Conclusion: CARD10 expression is increased in HCC tissues and positively correlated with HCC progression. CARD10 inhibits HCC apoptosis by promoting the activation of NF-κB pathway.
