Journal of Acupuncture and Tuina Science 2020;18(3):207-212
Objective: To observe the effect of electroacupuncture plus drug anesthesia on pain and stress response in patients after radical surgery for stomach cancer.Methods: A total of 60 patients were randomized into a control group and an observation group by the random number table, with 30 cases in each group. The control group was given conventional drug anesthesia. The observation group was given additional electroacupuncture intervention. Before anesthesia and 2 h, 12 h and 24 h after surgery, the visual analog scale (VAS) was scored, the heart rate, the mean arterial pressure, and the levels of serum β-endorphin (β-EP) and adrenocorticotrophic hormone (ACTH) were measured. Results: Two hours, 12 h and 24 h after surgery, the VAS scores of both groups were higher than those before anesthesia (all P<0.05), and the VAS scores in the observation group were lower than those in the control group at the same time points (all P<0.05). Two hours, 12 h and 24 h after surgery, the heart rates and mean arterial pressures in the control group were significantly higher than those before anesthesia (all P<0.05), while there were no significant intra-group differences in the observation group (all P>0.05), and the indicators were lower than those in the control group at the same time points (all P<0.05). Two hours, 12 h and 24 h after surgery, the serum β-EP levels in the observation group were significantly higher than those before anesthesia (all P<0.05), and significantly higher than those in the control group at the same time points (all P<0.05). Two hours, 12 h and 24 h after surgery, the serum ACTH levels in the control group were significantly higher than those before anesthesia (all P<0.05), and were significantly higher than those in the observation group at the same time points (all P<0.05). Conclusion: Electroacupuncture plus drug anesthesia can significantly relieve pain and stress response in patients after radical surgery for stomach cancer.

Objective To investigate the roles of phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) signaling pathway and its regulatory protein peroxisome proliferator-activated receptor γ (PPAR γ) and phosphatase and tension homologue deleted on chromosome 10 (PTEN) in regulating insulin sensitivity in rats with fetal growth restriction (FGR).Methods Sixteen pregnant rats were randomly divided into two groups including FGR and control groups on the 12th day of pregnancy (eight in each group).The FGR group was given low protein diet (8% of casein) and restriction diet to establish the neonatal rat model of FGR.All maternal rats after delivery and newborn rats after weaning on 21 days after born were fed with normal diet.Each time blood samples were collected from eight newborn rats of each group to measure levels of fasting plasma glucose (FPG) and fasting insulin(FINS) at the time points of 21 days,two and four months after birth.Then insulin resistance index (IRI) and insulin sensitivity index (ISI) were calculated to evaluate insulin sensitivity.Expression of PI3K,AKT,PPAR γγ,PTEN and glucose transporters 4 (GLUT4) in skeletal muscle at mRNA and protein levels were measured at 21 days,two and four months after birth with real time fluorescence polymerase chain reaction and Western blot,respectively.Relationships between the expression of key molecules of PI3K/AKT signaling pathway and insulin sensitivity were analyzed.T-test,and Pearson's correlation analysis were used for statistical analysis.Results (1) The average birth weight of newborn rats in the FGR group was lower than that of the control group [(4.37± 0.69) vs (7.03±0.55) g,t=-20.75,P<0.05].The incidence of FGR in the FGR group was 93.33% (70/75).(2) Compared with normal offspring,those in the FGR group showed significantly increased FPG [two months after birth:(5.53± 0.58) vs (7.49 ± 0.38) mmol/L,t=8.08;four months afterbirth:(6.35±0.66) vs (8.94±0.90) mmol/L,t=6.58],FINS [two months afterbirth:(9.18±0.66) vs (14.67± 1.90) mU/L,t=7.71;four months after birth:(33.08±2.76) vs (56.33±2.81) mU/L,t=16.71] and IR1 (two months after birth:2.25±0.31 vs 4.90±0.81,t=8.63;four months after birth:9.30±0.90 vs 22.44±3.10,t=1 1.51),but decreased ISI (two months after birth:0.020 ± 0.002 vs 0.009± 0.001,t=-10.1 4;four months after birth:0.005±0.000 vs 0.002 ±0.000,t=-14.91) at two and four months after birth (all P<0.05).(3) Compared with normal offspring,those in the FGR group showed decreased expression of PI3K (21 days after birth:0.082±0.028 vs 0.019±0.004,t=-6.29;two months after birth:0.020±0.003 vs 0.010±0.005,t=-4.78;four months after birth:0.014±0.004 vs 0.003±0.001,t=-7.87) and GLUT4 (21 days after birth:0.132±0.057 vs 0.041 ±0.019,t=-4.32;two months after birth:0.183±0.084 vs 0.069±0.017,t=-3.74;four months after birth:0.248±0.069 vs 0.113±0.040,t=-4.74) at mRNA level at 21 days,two and four months after birth (all P<0.05).Compared with normal offspring,decreased expression of PPAR γ (two months after birth:0.028±0.002 vs 0.012±0.005,t=-3.70;four months after birth:0.030±0.008 vs 0.012±0.005,t=-3.80) and increased expression of PTEN (two months after birth:0.020±0.004 vs 0.045±0.014,t=5.09;four months after birth:0.023±0.007 vs 0.034±0.009,t=2.57) at mRNA level were observed in offspring of the FGR group at two and four months after birth (all P<0.05).(4) Compared with normal offspring,expression of PI3K protein (21 days after birth:0.22±0.01 vs 0.17±0.02,t=-6.62;two months after birth:0.27±0.03 vs 0.16±0.02,t=-7.25;four months after birth:0.18±0.01 vs 0.09±0.02,t=-9.79) and GLUT4 protein (21 days after birth:0.21 ±0.01 vs 0.03±0.01,t=-27.29;two months after birth:0.10±0.01 vs 0.06t±0.01,t=-3.90;four months after birth:0.13 ±0.01 vs 0.08± 0.02,t=-8.10) decreased in offspring in the FGR group at 21 days,two and four months after birth (all P<0.05).Compared with normal offspring,those in the FGR group showed decreased expression of PPAR γ protein (two months after birth:0.10 ± 0.01 vs 0.07± 0.01,t =-7.29;four months after birth:0.09±0.01 vs 0.08±0.01,t=-2.83),but increased expression of PTEN at protein level (two months after birth:0.10±0.01 vs 0.15±0.02,t=6.01;four months after birth:0.09±±0.01 vs 0.13±0.02,t=5.51) at two and four months after birth (all P<0.05).(5) The IRI levels in offsprings in the FGR group were negatively correlated with the expression of PI3K,GLUT4 and PPAR γ at protein level (two months after birth:r=-0.90,-0.92 and-0.79;four months after birth:r=-0.92,-0.75 and-0.73,all P<0.05),but positively correlated with the expression of PTEN at protein level (r=0.87 and 0.86,both P<0.05) at two and four months after birth.Conclusions The abnormal expression of the key molecules of PI3K/AKT signaling pathway precedes the decrease of insulin sensitivity in newborn rats with FGR and the expression regulatory protein PPAR γ and PTEN are also changed,suggesting that these molecules may induce the impairment of insulin sensitivity in rats with FGR and be involved in the development of insulin resistance.

Objective To prepare lipid-coated ultrasound microbubbles containing 10-HCPT(HLM) and explore the antitumor effects on mice xenografed H22 solid tumor using the technique of ultrasound-mediated HLM destruction. Methods Sixty-four tumor-bearing mice were radomly divided into A and B groups. Each group was divided into four groups again and administered respectively by tail vein with HI.M, non-drug-loaded microbubbles,10-HCPT and saline once a day. Ultrasound irradiation was applied on the tumor sites immediately after injection. After 7 days of consecutive treatment, all mice in group A were sacrificed and the tumors were harvested to measure weights. The tumor inhibition rate was calculated by weights. The tumor microvessel density (MVD) was detected by immunohistochemical staining. The tumor growth curve was depicted according to volumes. The survival time of mice in group B was recorded. Results The tumor inhibition rate was the highest in HLM group while this group's MVD was the lowest. Survival time in HLM group and 10-HCPT group were obviously longer compared with the control group,while no statistic difference was observed between the two groups. There was no statistic difference between the group of non-drug-loaded microbubbles and the control group. Conclusions Ultrasound irradiation mediates HLM destruction so that the drug is released from the vihicles at the same time, which can significantly enhance the tumor inhibition effect of 10-HCPT on the H22 tumor. This technique is expected to be adopted as a novel tool for liver cancer chemotherapy.

Objective To determine the frequency of polymorphism at exon 26 (C3435T) of muhidrug resistance 1 gene (MDR1) in epileptic patients in the southern Chinese and to study the association of this polymorphism with pharmacoresistance.Methods DNA samples were obtained from 134 patients,of whom 72 were resistant to antiepileptic drug treatment and 62 were responsive to the treatment. Genotypes of the C3435T polymorphism were determined by polymerase chain reaction (PCR) followed by restriction digestion and gel electrophoresis.Genotype and allele frequencies in the drug resistant group were compared to those in the response group by Chi-square analysis.Results Of all 134 patients,33 (24.6%) had CC genotype,72 (53.7%) had CT genotype,and 29 (21.6%) had TT genotype.The frequency of CC genotype was significantly higher in the pharmaeoresistance group (33.3%) than that in the responsive group (14.5%,P=0.012).The frequency of the C allele was also significantly higher in the pharmacoresistance group (57.6%) than that in the responsive group (44.4%,P=0.03).When patients were divided by types of seizure into three groups:generalized seizure group,partial seizure group,and undefined seizure group,the CC genotype and C allele were associated with pharmacoresistance in the partial seizure group.Conclusions In the southern Chinese,the CC genotype and C allele are associated with resistance to the antiepileptic treatment.This finding needs to be verified in studies with larger sample size.
