1.Clinical trials of pemetrexed combined with carboplatin in treating 40 non-small cell lung cancer patients
Chinese Journal of Clinical Oncology 2013;(13):792-795
Objective: Pemetrexed (PEM) is a multi-targeted chemotherapeutic agent for antifolate drugs. PEM has become the standard agent for the second-line treatment of advanced non-small cell lung cancer (NSCLC). This study aims to review and analyze the clinical efficacy and adverse reactions of PEM combined with carboplatin with respect to NSCLC treatment. Methods: A total of 40 patients suffering from NSCLC were selected and confirmed by pathology. On the first day of treatment, the conventional 500 mg/m2 dose of pemetrexed disodium was infused intravenously. On the second day, a combined therapy with carboplatin was conducted based on the conventional dose for a 21-day cycle with at least two cycles for each patient. The therapeutic efficacy and adverse reactions were evaluated and were compared with the proposed regimen of gemcitabine (GEM) combined with carboplatin. Results: After two cycles of the treatment, the curative effects of the PEM and GEM groups were 50% and 45%, respectively. The main adverse reactions are bone marrow suppression and gastrointestinal reactions. The incidence rates of bone marrow suppression, gastrointestinal reactions, amisulpride/AST, urea nitrogen, rash, and hair loss were obviously lower in the PEM group than in the GEM group. Statistically significant differences in adverse reaction were found between the two groups (P<0.05). Conclusion: The use of the combination regimen of PEM with carboplatin showed significantly more clinical effects and less adverse reactions for NSCLC treatment.

4.Effect of Dexamethasone with Subdose Ketamine on Restraining the Pulling-dragging Reflex During Appendectomy
Journal of Chinese Physician 2000;0(11):-
Objective To investigate the effect of dexamethasone with subdose ketamine on restraining the pulling-dragging reflex during appendectomy. Methods 114 ASA grade Ⅰ~Ⅱpatients of appendectomy undergoing T 11 ~L 1 epidural anesthesia were randomly divided three groups,each group containing 38 cases. Group Ⅰ recieved the dexamethasone 10mg and ketamine 0 5mg/kg by venous injection before opening abdominal cavity, groupⅡ received pethidine 50mg and droperidol 2 5mg before begining operation, and group Ⅲ without any drugs served as control. The pulling-dragging reflex of appendix, the sedative state at pulling-dragging appendix and the change of pulse oxygen saturation (SpO 2) or mean arterial pressure (MAP) were recorded and analyzed. Results The excellent rates of groupsⅠ, Ⅱ and Ⅲ were 100%, 81 58% and 18 42% respectively,and there was significant difference between group I and the other groups (P

The degradation kinetics of chlorogenic acid (5-CQA), cryptochlorogenic acid (4-CQA), and neochlorogenic acid (3-CQA) in aqueous solution at 37 degrees C and different pH values (7.05, 7.96, 9.25) were investigated in the present work. The results indicated that 3-, 4- and 5-CQA tended to remain stable in acidic pH circumstance, and unstable in neutral and alkaline pH circumstance. With the increase of the alkalinity, the degradation of 3-, 4- and 5-CQA was increased leading to a less amount of total CQA and was satisfactorily described by the Weibull equation. Meanwhile, caffeic acid was not detected after the degradation of CQA. Moreover, the degradation of 3-CQA and 5-CQA tended to be converted to 4-CQA, and the degradation of 4-CQA tended to be converted to 3-CQA rather than 5-CQA. The comparison of the degradation kinetics parameters of 3-, 4- and 5-CQA at neutral and alkaline pH values showed that the orders of the rate constant (k) values were 4-CQA > 3-CQA > 5-CQA, while the orders of the degradation half life (t½) values were 4-CQA < 3-CQA < 5-CQA, indicating the orders of the stabilities of 3-, 4- and 5-CQA at 37 degrees C and neutral and alkaline pH values were 4-CQA < 3-CQA < 5-CQA.

Objective To compare the effects of different anesthetic and postoperative analgesic methods on the immune function of helper T lymphocytes and tumor metastasis after orthotopic liver cancer resection in rats.Methods Orthotopic liver cancer was induced by intrahepatic tumor implantation (IHTI) with Morris hepatoma 3924A.Thirty male ACI rats receiving IHTI,aged 12-18 weeks,weighing 240-300 g,were randomized into 3 groups (n =10 each) using a random number table:control group (group C),general anesthesia combined with epidural block-postoperative epidural analgesia group (group GE + EA),and general anesthesia-postoperative intravenous analgesia group (group G + IA).The liver cancer resection was performed on 14th day after IHTI,group G + IA inhaled 5% sevoflurane for induction of anesthesia and inhaled 2%-3% sevoflurane and received intraperitoneal injection of morphine 20 μg/100 g for maintenance of anesthesia.In group GE + EA,general anesthesia was performed as the method previously described in group G + IA,and epidural block was performed with 0.25 % bupivacaine 25 μl after tracheal intubation.Within 3 days after operation,0.125 % bupivacaine 150 μl + morphine 20 μg were injected daily via an epidural catheter once every 4 h (25μl per time) for postoperative analgesia in group GE + EA,and postoperative analgesia was performed with intraperitoneal morphine 240 μg injected daily once every 4 h (40 μg per time) in group G+ IA.Before surgery (T1) and on 2nd,7th and 30th days after sugery (T2-4),blood samples were collected to detect the levels of plasma interferon-γ (IFN-γ),interleukin-4 (IL-4),IL-17,IL-10 and tumor growth factor-β1 (TGF-β1).IFN-γ/IL-4 ratio was calculated.The rats were sacrificed after collecting blood samples at T4,and the development of abdominal lymph node metastasis,malignant ascites,implantation metastasis to abdominal wall and visible pulmonary metastasis nodules were observed.Results Compared with C group,the incidence of pulmonary metastasis,abdominal lymph node metastasis,and malignant ascites was significantly decreased,the plasma IFN-γ and IL-17 levels at T2 and IL-4 and TGF-β at T2,3 were increased,and IFN-γ/IL-4 ratio was decreased at T2,3 in group G+ IA,and the incidence of pulmonary metastasis,abdominal lymph node metastasis,malignant ascites and implantation metastasis to abdominal wall was significantly decreased,the plasma levels of IFN-γ,IL-4,IL-17,IL-10 and TGF-β1 were increased at T2(P < 0.05),and no significant change was found in IFN-γ/IL-4 ratio in GE + EA group (P > 0.05).Compared with G + IA group,the incidence of pulmonary metastasis and abdominal lymph node metastasis was significantly decreased,the plasma levels of IFN-γ and IL-17 at T2 and IL-4 and IL-10 at T3 were decreased,the plasma levels of IFN-γ at T4 and TGF-β1 at T2 and IFN-γ/IL-4 ratio at T3,4 were increased in GE + EA group (P < 0.05).Conclusion The inhibitory degree of the immune function of helper T lymphocytes is decreased and development of tumor metastasis is reduced after orthotopic liver cancer resection in rats when general anesthesia combined with epidural block-postoperative epidural analgesia is applied as compared with those when general anesthesia-postoperative intravenous analgesia is applied.
