The incidence of adenocarcinoma of esophagogastric junction is increasing worldwide during recent decades.The therapeutic strategies have been transformed from surgery alone to multimodal treatments involing also perioperative chemoradiotherapy.Although there are still many problems on preoperative staging,surgical approach,excisional extent and perioperative chemoradiotherapy regimen,multidisciplinary team collaboration can provide an optimal diagnosis and treatment to achieve the principles of standardization and individualization in malignant tumor,which will prolong the survival and improve the quality of life for every patient.

ObjectiveTo investigate rational surgical approaches for Siewert type Ⅰ adenocarcinoma of the esophagogastric junction (AEG),and analyze the prognostic factors.MethodsThe clinical data of 103 patients with Siewert type Ⅰ AEG who were admitted to the Renji Hospital from January 2005 to December 2009 were retrospectively analyzed.All patients were divided into transthoracic approach group (61 patients) and thoracoabdominal approach group (42 patients).The incidences of numbers of lymph node dissected and postoperative complications of the 2 groups were compared using the chi-square test,Fisher exact probability or the t test.The survival curve was drawn by the Kaplan-Meier method and the survival was analyzed using the Log-rank test.Prognostic factors were analyzed using the one-way analysis of variance and Cox regression model.ResultsNo perioperative death was observed in the 2 groups.There were significant differences in the number of lymph node dissected and number of metastatic lymph node between the 2 groups (t =2.18,2.29,P ＜ 0.05 ).There was no significant difference in splenic injury between the 2 groups (P ＞ 0.05 ).There were no significant differences in postoperative bleeding,anastomotic fistula and stricture,esophagogastric reflux,pulmonary infection and esteomyelitis between the 2 groups (x2 =0.07,0.94,0.22,1.41,0.17,P＞0.05).Of the 103 patients,97(94.2％) were followed up.The mean postoperative survival time was 26 months.The median survival time was 26 months,and the 3-yearsurvival rate was 35.9％.The 3-year survival rates of transthoracic approach group and thoracoabdominal approach group were 32.8％ and 40.2％,with no significant difference between the 2 groups ( x2 =0.37,P ＞ 0.05).The results of univariate analysis showed that radical or palliative resection,TNM stage,lymph node metastasis stage,tumor diameter and metastasis rate,degree of radical resection were independent factors influencing the prognosis of patients with Siewert type Ⅰ AEG (x2 =21.07,26.04,22.42,6.26,32.20,20.80,P＜0.05).The results of multivariate analysis showed that degree of TNM stage,lymph node metastasis rate and radical resection were independent factors influencing the prognosis of patients ( Wald =12.01,8.75,10.03,P ＜ 0.05 ).Conclusions Thoracoabdominal approach is a reasonable selection for patients with Siewert type I AEG.Degree of TNM stage,lymph node metastasis rate and radical resection were independent risk factors influencing the prognosis of patients.

There is no radical cure for essential thrombocythemia currently. Professor SUN Xue-mei has extensive clinical experience in treating it by combined therapy of Chinese and Western medicine. In this paper, authors tried to summarize her experience from guiding ideology and therapeutic points. Authors insisted on the direction of integrative medicine on the basis of syndrome differentiation, paying attention to psychological counseling,and applied individual treatment in clinics.

AimTo establish a model of the injury of the vascular endothelial cell(VEC) in rats and observe the function of Chinese herbs of Li Qi Huo Xue(LQHX) will prevent and treat the VEC injury. Methods30 SD rats weredivided into the control, the model and LQHX groups. The model of the VEC injury was established. It tried to demonstrate the effect of LQHX for the coagula tion and fibrinolysis function of the VEC by the C EC count,t-PA, PAI activity, 6-keto-PGF1αcontent and PAgTmax. Results In LQHX group as compared with those of the medol group, The CEC count was redued obviously(P＜0.01). t-PA activity was increased(P＜0.01), so did the percentage of active t-PA(P＜0.01), but PAI activity decreased (P＜0.05), 6-keto-PGF1α content increased (P＜0.01)α the PAgTmax decreasd (P ＜0.01) Conclution LQHX can enhance the anticoagulation and fibrinolysis activities. It is a more effective measure for the VEC protection.

Objective To investigate the influence of CO2 pneumoperitoneum on the adhesive and invasive ability of gastric cancer cells based on the expression of adhesive and invasive molecules. Methods With an artificial CO2 pneumoperitoneum model in vitro, human gastric cancer cells MKN-45, SGC-7901 and MKN-28 were exposed to 3 different CO2 gradients: 9 mm Hg, 15 mm Hg and control group (0 mm Hg). The expression of E-cadherin, ICAM-1, MMP-2 and VEGF-A were measured at 2 and 4 hours exposure by using RT-PCR, CytoMatrixTM kit and ECMatrixTM kit. The pretreated gastric cancer cells were injected into abdominal cavity of nude mice(2×106 cells per mouse). Five mice in each group were sacrificed 4 weeks later to record the number of tumor nodules in abdominal cavity. The remaining mice were kept for observation of survival time. Results The expression of E-cadherin (MKN-45: from 2.26 to 2.19, SGC-7901 :from 2.16 to 2.09、MKN-28 :from 2.06 to 1.99), ICAM-1 (MKN-45 : from 2.20 to 2.28、SGC-7901: from 2.10 to 2.18、MKN-28: from 2.00 to 2.08), MMP-2 (MKN-45:from 2.05 to 2.13、SGC-7901: from 1.95 to 2.03、MKN-28: from 1.85 to 1.93) and VEGF-A(MKN-45 : from 2.10 to 2.16、SGC-7901 :from 2.00 to 2.06、MKN-28: from 1.90 to 1.96) didn't change significantly with increasing pressure and time (P>0.05). The expression of adhesive and invasive molecules didn't change significantly between the experimental groups and the control group. There was no statistical significance of tumor metastasis in abdominal cavity of nude mice(MKN-45:from 22 to 23、SGC-7901 :from 20 to 22、MKN-28:from 21 to 22) and survival time(MKN-45 :from 23 to 21、SGC-7901 :from 22 to 21、MKN-28 :from 22 to 21) among all the groups. Conclusion Under low pressure and short time of CO2 exposure, the adhesive and invasive capacity of gastric cancer cells did not change significantly hence did not increase the possibility of neoplasm metastasis.

Objective To explore the diagnosis and re-operation of the recurrent retroperitoneal soft tissue sarcoma(RPS).Methods Clinical data of 25 patients with recurrent RPS were retrospectively analyzed.Results All of 25 cases of recurrent RPS were diagnosed by operation and postoperative pathologic examination.They underwent a total of 42 time operations,with mean time of re-operations was 1.68.Of the 42 time operations,26 time were complete resection,11 time partial resection and 5 time only biopsy.A total of 19 cases underwent removal of contiguous intra-abdominal organs and 5 underwent resection of major invaded blood vessel.The 1-,3-and 5-year survival rate of recurrent RPS was 52.0%,40.0% and 28.0% respectively.The rate of complete resection in recurrent RPS with major blood vessel invasion was 35.7%.In contrast,the complete resection rate in recurrent RPS without major blood vessel invasion was 75%(P=0.013).On the other hand,there was no significant difference in complete resection rate between the recurrent RPS with adjacent organs invasion and the recurrent RPS with no adjacent organs invasion(P=0.462).Conclusions Preoperative imaging results are crucial factor for assessment of operative resectability.Unless there are obvious comtraindications,recurrent RPS should undergo aggressive surgical excision.

OBJECTIVE:To screen the optimal technology of dog testes and penis processed with talcum powder,and to pro-vide reference for the formulation of quality control standard. METHODS:Taking the comprehensive score of crushing rate and the content of alcohol soluble extract as evaluation indexes,L9(34) orthogonal test was used to optimize processing temperature,pro-cessing time and the amount of talcum powder;validation test was conducted. According to related method in Chinese Pharmaco-poeia(2015 edition),the contents of moisture,ash,nitrogen and alcohol soluble extract were determined,and automatic amino ac-id analyzer was used to determine the content of amino acids in samples. RESULTS:The optimal processing technology were that 100 kg dog testes and penis should add into 40 kg talcum powder;the processing temperature was 350-380 ℃;processing lasted for 4 min. Results of verification test showed that the average crushing rate and the content of alcohol soluble extract were 80.2%(RSD=0.95%,n=3)and 15.7%(RSD=2.30%,n=3). In processed dog testes and penis,the contents of moisture,ash,nitro-gen and alcohol soluble extract were 5.7%,18.7%,8.3%,15.7%,respectively. Besides,there still were 16 kinds of amino ac-ids,and their total content was 42.44%. CONCLUSIONS:The optimized talcum powder processing technology of dog testes and penis is stable and practical. The content of moisture,ash,nitrogen,alcohol soluble extract and amino acid can be used as impor-tant quality standard control indexes for processed dog testes and penis.
