Effect of anesthetic methods on postoperative CD3+, CD4+ and CD4+CD25+ in patients with lung cancer undergoing radical operation.

Effects of anesthesia methods on immune function in patients with lung cancer undergoing radical operation were investigated. A total of 122 patients undergoing radical resection of lung cancer who were treated in Zhejiang Cancer Hospital from September 2013 to April 2016 were randomly divided into the combined anesthesia group and the intravenous anesthesia group, with 61 cases in each group. The patients in the combined anesthesia group were given intravenous combined epidural anesthesia. Patients in the intravenous anesthesia group were given intravenous anesthesia. The change of CD3+, CD4+ and CD4+CD25+ at time-point T0 (before anesthesia), T1 (the time of anesthesia), T2 (after operation), T3 (24 h after operation), T4 (72 h after operation) were compared between the two groups. The levels of CD3+, CD4+ and CD4+CD25+ at T1, T2, T3 and T4 in the combined anesthesia group were higher than that in the intravenous anesthesia group (P<0.05). Αfter starting anesthesia, the levels of CD3+, CD4+ and CD4+CD25+ began to decrease in both groups. The levels of CD3+, CD4+ and CD4+CD25+ at T2 and T1 were lower than those at T0 (P<0.05). The levels of CD3+, CD4+ and CD4+CD25+ at T2 were lower than T1 (P<0.05). After T3, the levels of CD3+, CD4+ and CD4+CD25+ began to increase in both groups. Τhe levels of CD3+, CD4+ and CD4+CD25+ at T3 and T4 were higher in both groups than those at T2 and T1 (P<0.05), and the levels of CD3+, CD4+ and CD4+CD25+ at T4 were higher in both groups than those at T3, but the levels of CD3+, CD4+ and CD4+CD25+ at T3 and T4 were lower than those at T0 (P<0.05). Intravenous combined epidural anesthesia can maintain a relatively stable immune function compared with simple intravenous anesthesia patients.

Effect of qubi zhentong recipe on synovial gene expression in collagen-induced arthritis in rats.

OBJECTIVE: To investigate the effect of the Chinese medical formula Qubi Zhentong Recipe(, QZR) on the synovial gene expression profile in collagen-induced arthritis (CIA) rats. METHODS: Ten rats were randomly chosen from 60 rats as the control group, and the other 50 rats were used for the CIA models. The CIA model group was constructed by bovine injection of type II collagen through the rats' neck and tail. Twenty rats were randomly chosen from 34 successful CIA models and randomly assigned into two groups: the model group (n =10) and the QZR group (n=10). The QZR group was fed intragastrically with QZR 22.9 g/(kg·d) (10 times the clinical adult dose), and the CIA model group was given the same dose of normal saline. Both model and QZR groups were administered treatment once a day. Total RNA was collected from the knee joint synovium after 30 days. The change in gene expression profile was analyzed by a whole gene chip. RESULTS: A total of 76 genes showed a difference in expression between CIA model group and the control group; 35 genes were down-regulated and 41 were up-regulated. A total of 67 genes showed a difference in expression between the model group and the QZR group; 48 genes were down-regulated and 19 were upregulated. CONCLUSIONS: QZR may affect CIA by stimulating multiple genes and targets, which are related to oncogenes, apoptosis, metabolism, the immune system, ion channels, and transport proteins.

[Effects of qubi zhentong recipe on the expressions of IL-1beta, IL-8, and VEGF in the synovial of rats with collagen-inducing arthritis].

OBJECTIVE: To research the effects of Qubi Zhentong Recipe (QZR) on the expressions of interleukin-1beta (IL-1beta), interleukin-8 (IL-8), and vascular endothelial growth factor (VEGF) in the synovial of rats with collagen-inducing arthritis (CIA), and to discuss its mechanisms of action. METHODS: Healthy male Wistar rats were recruited and randomly divided into the model group ( n = 50) and the normal control group (n = 10). Rats of the model group were injected with type II collagen of bovine (BC II) emulsion in the tail and nape to establish the CIA model. After successful modeling, 30 successfully modeled rats were selected and randomly divided into three groups, i.e., the model group (n = 10), the QZR group (n = 10), and the methotrexate (MTX) group (n = 10). Rats in the normal control group and the model group were administered with physiological saline by gastrogavage, while those in the QZR group were administered with QZR at 22.9 g/kg by gastrogavage. All medication was performed once daily. The rats in the MTX group were administered with MTX suspension at 0.78 mg/kg by gastrogavage, once per week. After 30-day treatment, the levels of IL-1beta, IL-8, and VEGF in the synovial were detected by immunohistochemical method. The arthritis index (AI) was scored before and after medication. RESULTS: After treatment the AL score of the QZR group and the MTX group was obviously lower than that of the model group (P < 0.01). The AI score of the two drug groups were lower than that before treatment (P < 0.01). Compared with the normal control group, the expression levels of IL-1beta, IL-8, and VEGF obviously increased in the model group (P < 0.01). Compared with the model group, the expression levels of IL-1beta, IL-8, and VEGF were significantly lower in the two drug groups (P < 0.01). But there was no statistical difference between the QZR group and the MTX group (P > 0.05). CONCLUSION: Decreasing the expression levels of IL-1beta, IL-8, and VEGF in the synovial of CIA rats may be one of the mechanisms for treating CIA by QZR.

[Observation on the analgesic effect of transcutaneous electrical acupoint stimulation for breast radical carcinoma operation].

OBJECTIVE: To observe the analgesic effect of transcutaneous electrical acupoint stimulation (TEAS) in assisting general anesthesia (GA) for radical operation of breast carcinoma so as to explore its clinical application value. METHODS: Sixty patients scheduled for radical operations of the breast carcinoma were randomly and equally divided into GA group and TEAS+ GA group. For GA, Propofol [4.5 microg/mL, target concentration; (3.0 +/- 0.5) microg/mL during operation] was used in combination with Sufentanil (0.25 microg/kg) and Cis-atracurium amine (0.2 mg/kg). TEAS (5-10 mA, 2 Hz/100 Hz) was applied to Hegu (LI 4)-Laogong (PC 8) and Neiguan (PC 6)-Waiguan (SJ 5) on the affected side of the body for 30 min. Heart rate (HR), mean aterial pressure (MAP), tube removing time and postoperative complications were recorded. Plasma beta-endorphin content was assayed by radioimmunoassay. RESULTS: After anesthesia, patients with reduction in MAP in GA group were significantly more than those in TEAS+GA group (P < 0.05), and their HR decreased remarkably (P < 0.05). After tracheal intubation, MAP in TEAS+GA group kept relatively stable, which was superior to that of GA group (P < 0.05). In comparison with GA group, the patients' analepsia time and tube withdrawal time of TEAS+ GA group were significantly shorter; and the dosage of analgesics of TEAS+GA group was significantly smaller than that of GA group (P < 0.05). Patients with complications of pain, restlessness, drowsiness, nausea and vomitting were obviously fewer in TEAS + GA group than those in GA group. Compared with GA group, plasma beta-endorphin content in TEAS+GA group increased considerably 30 min after TEAS, 5 min after skin-incision and after operation (P < 0.05). CONCLUSION: TEAS combined with general anesthesia for breast radical carcinoma operation can help keep a stable blood pressure during surgery, reduce the dosage of analgesics and strengthen pain relief. The analgesic effect of TEAS may be related to its effect in up-regulating plasma beta-endorphin level.
