RESUMO
Objective: To observe the effect of electroacupuncture (EA) at different time points during the perioperative period on the recovery of gastrointestinal function after gastrointestinal malignant neoplasms surgery. Methods: Sixty-three patients who needed radical surgery for gastrointestinal tumors were randomized into a control group, treatment group 1 (postoperative EA group), and treatment group 2 (intraoperative and postoperative EA group). The control group received surgery and conventional Western medicine treatment, and treatment groups 1 and 2 received additional EA treatment at different time points. The initial flatus time after the surgery, visual analog scale (VAS) score at different time points after the surgery, the proportion of using patient-controlled analgesia (PCA) after the surgery, and the times of adding analgesics were observed in the three groups. Results: The initial flatus time after the surgery was earlier in treatment groups 1 and 2 than in the control group (P<0.05); the difference between treatment groups 1 and 2 was statistically insignificant (P>0.05). The VAS score was lower in treatment group 2 than in the control group at 6, 12, 24, and 72 h after the surgery (P<0.05); the VAS score was lower in treatment group 1 than in the control group only at 72 h after the surgery (P<0.05). There were no significant differences in the rate of using PCA among the three groups (P>0.05). Regarding the times of adding analgesics, it was less in treatment group 2 than in the control group at 12 h after the surgery (P<0.05). Conclusion: Either EA during and after the surgery or only after the surgery can hasten the initial flatus and boost the recovery of gastrointestinal function in patients after radical resection of gastrointestinal neoplasms. Successive EA during and after the surgery should be superior to postoperative EA regarding the analgesic effect after the surgery.
RESUMO
ObjectiveTo discuss the changes in characteristics of N-glycan in gastric cancer and its relationship with TCM syndromes.Methods The blood samples of 138 gastric cancer patients and 120 healthy volunteers were collected. The changes in N-glycan were detected by DNA sequencer-assisted and fluorophore-assisted carbohydrate electrophoresis (DSA-FACE), and differences of N-glycan among different TCM syndromes were compared.Results At least 9 N-glycan peaks could be identified in all samples. Compared with the healthy volunteers, Peak1, Peak5, Peak9 and Peak2 of gastric cancer patients obviously increased (P<0.05,P<0.01), whereas Peak3, Peak6 significantly decreased (P<0.01). Peak6 of gastric cancer in stage I was obviously higher than stages II, III, and IV (P<0.01), while Peak9 in stage I was obviously lower than the other three stages (P<0.01). Peak1 was significantly lower in disharmony between liver and stomach type than stagnation of phlegm-dampness type, interior retention of toxin stagnation type, deficiency of both Qi and blood type (P<0.05,P<0.01);lower in impairment of yin due to stomach heat type, deficiency-cold in spleen and stomach type than deficiency of both Qi and blood type (P<0.01);lower in stagnation of phlegm-dampness type, interior retention of toxin stagnation type than deficiency of both Qi and blood type (P<0.05). Peak6 was higher in disharmony between liver and stomach type than impairment of yin due to stomach heat type, stagnation of phlegm-dampness type, interior retention of toxin stagnation type than deficiency of both Qi and blood type (P<0.01). Peak9 was much higher in deficiency of both Qi and blood type than disharmony between liver and stomach type (P<0.01), impairment of yin due to stomach heat type and deficiency-cold in spleen and stomach type (P<0.05, P<0.01).Conclusion The expression of N-glycan was specifically changed in gastric cancer. These variations could promote the metastasis of gastric cancer and potentially have certain correlation with TCM syndromes.
RESUMO
Objective To investigate the changes of serum gastrin level in patients with colon cancer and the relationship between serum gastrin level and colon cancer occurrence and development.Methods Data of 35 patients underwent colon cancer surgery from January 2010 to January 2012 in our hospital were collected,at the same time data of 28 patients with colonic polyps and 30 cases of normal were collected as normal control.Serum gastrin levels were tested by radioimmunoassay in patients with colon cancer before surgery,1,3,7 d after surgery and they were analyzed.Results The serum gastrin level of patients with colon cancer was significantly increased compared with colon polyps and healthy controls((92.45 ± 12.98) ng/L vs (49.66 ±10.34) ng/L vs (30.12 ±6.39) ng/L;F =9.455,P ＜0.001)).Serum gastrin level in patients with obstructive colon cancer was significantly higher than that in non-obstructive cancer((129.84 ± 15.32) ng/L vs (75.34 ±11.45) ng/L,t =12.181,P ＜0.001) ;Serum gastrin levels in patients who cut off colon tumor was signifcanfly lower than before surgery((43.02 ±8.34) ng/L,(40.74 ±6.78) rig/L,(38.12 ±7.09) ng/L vs (89.45 ±12.98) ng/L;P ＜0.05).But no significant change of serum gastrin levels in patients with the colon tumor compared with the preoperative((97.34 +8.30) ng/L vs (95.82 ±7.20) ng/L vs (94.44 ±7.74) ng/L vs (100.23 ± 10.82) ng/L; P ＞ 0.05).But there was significant difference on serum gastrin levels between patients who cut off colon tumor and patients with the colon tumor(within groups:F =8.341,P =0.012 ;between groups:F =7.871,P =0.024).Conchusion Serum gastrin levels in patients with colon cancer were significantly higher than that of patients with colon polyps and normal controls.There was also a significant reduction of serum gastrin in tumor resection,and therefore gastrin may be involved in the development of colon cancer.
