2.Research progress in Caveolin-1s' role in gastrointestinal cancer
Journal of International Oncology 2010;37(12):933-935
Caveolin-1 is an important surface structural marker of Caveolae. It is closely involved in the proliferation, apoptosis, invasion, metastasis, angiogenesis, signal transduction and multi-drug resistance of various tumor cells. Recent studies have found that altered Caveolin-1 expression has dual roles, as a tumor suppressor and promoter, in different stages of gastrointestinal cancer development and progression. The exact mechanisms of Caveolin-1s' involvement in the development of gastrointestinal cancer remain to be clarified and have attracted the attention of a lot of researchers.
3.Research progress on circulating tumor cells and their detection in colorectal cancer
China Oncology 2015;25(11):854-860
Colorectal cancer is one of the most common malignant tumors. Though the development of multidisciplinary therapy has largely improved the therapy effects, many patients still died of local recurrence and metastases after surgery. Circulating tumor cell (CTC) originates from primary tumor tissues and has a close relationship with cancer metastases and prognosis. This review summarizes the CTC detection methods and relevant clinical research on CTC in recent years.

Objective To investigate the efficacy of patient-controlled epidural analgesia(PCEA)with ropivacaine plus fentanyl for postoperative analgesia after suprapubic prostatectomy(SPP).Methods Thirty-six ASAⅡorⅢpatients aged 62-78 yrs weighing 52-84 kg undergoing SPP were randomly divided into 3 groups with 12 patients in each group:groupⅠreceived PCEA with 0.12% ropivacaine and fentanyl 1?g?ml~(-1);groupⅡreceived PCEA with 2% ropivacaine and fentanyl 1?g?ml~(-1) and groupⅢreceived patient-controlled intravenous analgesia(PCIA)with morphine 0.2 mg?ml~(-1).Postoperative pain was assessed using VAS(0=no pain,10= worst pain).The degree of motor blockade(modified Bromage scale)was evaluated at 6,24,48 and 72 h after operation(T_(1-4)).Bladder spasm episodes were recorded.Side effects including nausea,vomiting and pruritus and the total number of RBC in rinse solution were also recorded.Results(1)Bromage score(0=no motor block,3 =inability to flex ankle joint)was significantly higher in groupⅠandⅡthan in groupⅢat T1(6 h after op.), but significantly lower in groupⅠandⅢthan in groupⅡat T_(2-4)(24-72 h after operation).(2)VAS score(0= no pain,10=worst pain)was not significantly different among the 3 groups without bladder spasm but significantly higher in groupⅢthan in other 2 groups during episodes of bladder spasm.(3)The number of bladder spasm episodes was not significantly different among the 3 groups within 6h after operation,but was significant larger in groupⅢthan in the other two groups during 6-72 h after operation.During 6-24 h after operation more bladder spasm attacks occurred in groupⅠthan in groupⅡ.(4)The incidence of side effects was significantly lower and the total number of RBC in rinse solution was significantly smaller in groupⅠandⅡthan in groupⅢConclusion PCEA with 0.12% or 2% ropivacaine plus fentanyl can effectively reduce the number of bladder spasm attack and postoperative bladder bleeding.Different concentrations of ropivacaine should be used for PCEA during different postoperative periods.

Background and purpose:Resistance to antitumor agents is a major cause of treatment failure in patients with breast cancer. Research has shown that, tumor stem cell marker aldehyde dehydrogenase 1 (ALDH1) is related with some anticancer drugs (such as cyclophosphamide, cisplatin) resistance, and the content of ALDH1 in tumor cells after treatment is higher than that before treatment. Breast cancer resistance protein (BCRP) is not expressed in normal tissues, but high expressed in breast cancer of after treatment, it may be associated with the mechanism of tumor drug resistance. This study was to investigate the correlation between expression and the relationship between these two kinds of protein ALDH1, BCRP and clinical pathological characteristics. Methods:Immunohistochemistry was performed to detect the expression of ALDH1 and BCRP in breast inifltrating ductal carcinoma tissues, and whether there is a correlation between and explore their relationship with clinical pathological features and their expression. Results:The expression of ALDH1 protein and BCRP protein in breast cancer and paracarcinoma breast tissues has signiifcant difference(χ2=14.685, P=0.000;χ2=12.243, P=0.000).The expression of ALDH1 with patients age, pathologic stage, axillary lymph node metastasis, histological grading, ER, PR, and HER-2 state were not relevant(P>0.05). HER-2, BCRP protein, expression was higher in cancer tissue (χ2=5.289, P=0.021). There were no relevant with the expression of BCRP with patients age, pathologic stage, axillary lymph node metastasis and histological grading, estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor (HER-2) (P>0.05). Conclusion:ALDH1 proteins may be an independent factor compared with occur drug resistant protein, and participate breast cancer drug resistance in the chemotherapy and tumor invasion and metastasis of malignant biological behavior.

Objective: To study the antitumor effect of the protein from Tricholoma matsutake against HeLa cells in vitro. Methods: Active protein was separated from the mycelium after sub-merged fermentation, and the antitumor effect against HeLa cells was studied in vitro by cell growth inhibition, scanning electron microscope, flow cytometry and DNA electrophoresis. Results: The mycelium protein-TMP-B had strong antitumor effect and induced apoptosis in vitro. TMP-B inhibited cell proliferation and induced cell apoptosis by arresting cell conversion from S to G 2/M state. HeLa cells exposed to TMP-B showed apoptotic peaks. Agarose gel electrophoresis of DNA from cells treated with TMP-B revealed "DNA ladder". Conclusion: The mycelium protein from Tricholoma matsutake can inhibit cervix cancer cells--HeLa cell proliferation and induce apoptosis.

Objective To investigate the effect of partial liquid ventilation(PLV) with perfluorocarbon(PFC) on pulmonary surfactant during beatment of acute lung injury(ALI) induced by oleic acid. MethodsTwenty-four male Japanese white rabbits weighing 2. 1-2.6 kg were randomly divided into three groups(n = 8 ineach group): groupl: normal animal + mechanical ventilation (MV); group 2: ALI + MV; group 3: ALI +PLV.The animals were anesthetized with intraperitoneal ketamine 100 mg/kg, trachectomized and mechanicallyventilated (FiO_2 = 1, RR = 35 bpm, I: E = 1: 2, PEEP = 5 cm H_2O, PaCO_2 was maintained at 35-45 mm Hg byadjustment of tidal volume) .In group 2 and 3 ALI was induced by infusion of oleic acid 150?g/kg via centralvenous catheter over 30 min period. ALI was considered established when PaO_2 /FiO_2 was

Objective To investigate the accuracy of end-tidal carbon dioxide (PETCO2) in reflecting arterial carbon dioxide (PaCO2) during mechanical ventilation via laryngeal mask airway (LMA) in children. Methods Fifty-two ASA Ⅰ patients, aged 2-9 yr, weighing 10-30 kg, undergoing orthopaedic surgery under general anesthesia, were randomized into 2 groups (n = 26 each) : LMA group and endotracheal tube (ETT) group. After anesthesia was induced with fentanyl, propofol and succinycholine, LMA or ETT was inserted and the children were mechanically ventilated. After the hemodynamics was stable, arterial blood samples were obtained to detect PaCO2, and PETCO2 was recorded simultaneously. Results There was no significant difference in PaCO2 and PCT CO, between groups LMA and ETT ( P > 0.05) . There was no significant difference between PaCO2 and PETCO2 in LMA group (P > 0.05). Conclusion When mechanical ventilation is performed via LMA in children, PETCO2 can reliably reflect PaCO2 and guide the regulation of ventilatory parameters.
