The effect of acupuncture at the acupoints of 12 meridians on gastrointestinal and cardiac electricity in healthy adults was studied. Specific regulation between meridian points and viscera was also investigated. An electrogastrogram (EGG),electrointestinogram (EIG), carotid pulse graph, phonocardiogram and electrocardiogram were obtained in 30 healthy adults before and after acupuncture at various acupoints of 12 meridians. The effects of acupuncture on the amplitude and frequency of the EGG, EIG, pre-ejection period and the left ventricular ejection time were then analyzed. Acupuncture revealed that LR3 decreased the amplitude of the EGG while LI11 (Quchi), SJ5 (Waiguan), ST36 (Zusanli), SP9 (Yinlingquan) and SI6 (Yanglao) increased the amplitude. Multiple comparisons among the latter five acupoints indicated that there were significant differences between SP9, LI11, SJ5and ST36 (p < 0.01, p < 0.01, p < 0.05) and SI6, LI11 and SJ5 (p < 0.01, p < 0.05). SP9effected EGG amplitude the most, followed by SI6, ST36, SJ5 and LI11. Four acupoints increased the amplitude of the EIG (p < 0.05), including HT5 (Tongli), GB34(Yanglingquan), SP9 and SI6. No significant differences were observed between these acupoints, but SI6 showed the most obvious effect on EIG amplitude, followed by GB34, SP9 and HT5. No significant effects on the frequency of the gastrointestinal slow wave or on cardiac function indexes were observed. Effects were observed, however,on pre-ejection period and left ventricular ejection time. Routine acupuncture had no detrimental effects on the stomach, intestine and heart in healthy adults,but instead regulated physiological function within a normal range. These findings demonstrate the existence of specific connections between the meridian points and the viscera. The results suggest that multiple meridians control the same viscus,and the same meridian can regulate the functions of multiple viscera.

Objective: To observe treatment effects and safety of fluvoxamine combined with oxycodone prolonged-release tablets in treating patients with moderate to severe cancer pain. Methods: Patients confirmed pathologically with cancer and complicated with moderate to severe pain, were divided into control and experimental groups. Oxycodone prolonged-release tablets, with or without fluvoxamine, were administrated to all study patients until pain relief. Degree of pain relief, dose of oxycodone prolonged-release tablets, side effects and quality of life were compared before and after treatment. Results: In total, 120 patients were recruited. No statistically significant difference was detected regarding age, gender, types of cancer, KPS between two groups of patients (P>0.05). Baseline pain score of patients with moderate pain in treatment and control group was $4.9{\pm}0.8$ and $5.1{\pm}0.8$, respectively; and decreased to $1.8{\pm}1.1$ and $1.2{\pm}1.1$ after treatment, respectively. Pain intensity was significantly reduced in the treatment group (P=0.028). Average daily consumption of oxycodone prolonged-release tablets was ($54.0{\pm}19.6$) mg and ($44.7{\pm}18.7$) mg respectively, which is lower in treatment grpup than in control group, but the difference was not statistically significant (P=0.065). Baseline pain score of patients with severe pain in treatment and control groups were $8.3{\pm}1.1$ and $8.3{\pm}1.1$, respectively; and pain intensity after treatment decreased to $2.9{\pm}1.0$ and $2.3{\pm}1.0$. Pain intensity was significantly reduced in the treatment group, with statistical significance (P=0.026). Average daily consumption of oxycodone prolonged-release tablets was ($132.0{\pm}42.2$) mg and ($110.7{\pm}33.9$) mg, respectively, which is lower in treatment group than in control group, and the difference was statistically significant (P=0.035). In terms of quality of life, patients in treatment group had better performance status, daily activity, mood, and sleep than that in control group (P < 0.05). Patients in two groups had similar side effects, eg., constipation, nausea/vomiting, lethargy, dizziness, itchy skin, dysuria, and ataxia. Lower incidence of nausea/vomiting, lethargy, was obtained from patients in treatment than in control group, while significant low constipation was observed in treatment than in control group (35.0% vs 49.2%, P=0.026). Conclusion: Fluvoxamine combined with oxycodone prolonged-release tablets could be more effective in treating patients with cancer pain, and could reduce the dosage of oxycodone prolonged-release tablets and thus be associated with lower side effects, and improved quality of life.

Sodium glucose co-transporter 2 (SGLT-2) inhibitors are newly developed but promising medicine for type 2 diabetes. However, patients with a different renal threshold for glucose excretion (RTG) may have a different reaction to this medicine. Therefore, the objective of this study was to investigate the characteristics of RTG and its impact factors in patients with type 2 diabetes mellitus (T2DM). The clinical and laboratory data of 36 healthy individuals and 168 in-hospital patients with T2DM were collected and analyzed, RTG was calculated using blood glucose (BG) measured by dynamic BG monitoring, urinary glucose excretion (UGE) and estimated glomerular filtration rate (eGFR). The characteristics of RTG were investigated. The risk factors for high RTG were analyzed using non-conditional logistic regression analysis. Our results found that RTG of the T2DM group was higher than that of the healthy individuals (P < 0.05); and 22.22% from the healthy individuals group but 58.33% from the T2DM group had high RTG. Age, duration of diabetes, body mass index (BMI), and homeostasis model assessment insulin resistance index (HOMA-IR) were independently associated with high RTG (P < 0.05). Further stratified analysis revealed that RTG in T2DM patients increased with age, duration of diabetes, and BMI. In conclusion, RTG is increased in patients with T2DM, especially in those with longer diabetic duration, higher BMI, and those who are older. Therefore, these patients may be more sensitive to SGLT-2 inhibitors.

Hui Chang,Jia-wang Wei,Ya-lan Tao,Pei-rong Ding,Yun-fei Xia,Yuan-hong Gao,Wei-wei Xiao 대한암학회 2018 Cancer Research and Treatment Vol.50 No.4

Purpose This study aimed to explore the functions and mechanisms of C-C motif chemokine receptor 6 (CCR6), a gene associated with progression and metastasis of colorectal cancer (CRC), in radiosensitivity of rectal cancer (RC). Materials and Methods RNA sequencing and immunohistochemical analysis on CCR6 expression were performed in pretreatment tissues of RC patients exhibiting different therapeutic effects of radiotherapy. Colonogenic survival assay was conducted in different CRC cell lines to assess their radiosensitivity. And the impact of CCR6 expression on radiosensitivity was validated through RNA interference. The DNA damage repair (DDR) abilities of cell lines with different CCR6 expression were evaluated through immunofluorescence-based H2AX quantification. Results The CCR6 mRNA level was higher in patients without pathologic complete remission (pCR) than in those with pCR (fold changed, 2.11; p=0.004). High-level expression of CCR6 protein was more common in the bad responders than in the good responders (76.3% vs. 37.5%, p < 0.001). The CRC cell lines with higher CCR6 expression (LoVo and sw480) appeared to be more radioresistant, compared with the sw620 cell line which had lower CCR6 expression. CCR6 knockdown made the LoVo cells more sensitive to ionizing radiation (sensitization enhancement ratio, 1.738; p < 0.001), and decreased their DDR efficiency. Conclusion CCR6 might affect the RC radiosensitivity through DDR process. These findings supported CCR6 as a predicting biomarker of radiosensitivity and a potential target of radiosensitization for RC patients.

Zhang, Sheng-Chang,Huang, Peng,Zhao, Yong-Xiang,Liu, Shu-Yan,He, Shu-Jia,Xie, Xiao-Xun,Luo, Gou-Rong,Zhou, Su-Fang Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.4

Senescence marker protein 30 (SMP30), a hepatocellular carcinoma (HCC) associated antigen, was earlier shown by our research group to be highly expressed in HCC paracancerous tissues, but have low levels in HCC tissues. In order to detect anti-SMP30 antibody in serum of HCC patients, we established pET30a-SMP30 and pColdIII-SMP30 expression systems in Escherichia coli. However, the expression product was mainly in the form of inclusion bodies. In this research, we used several combinations of chaperones, four molecular chaperone plasmids with pET30a-SMP30 and five molecular chaperone plasmids with pColdIII-SMP30 to increase the amount of soluble protein. Results showed that co-expression of HIS-SMP30 with pTf16, combined with the addition of osmosis-regulator, and a two-step expression resulted in the highest enhancement of solubility. A total of 175 cases of HCC serum were studied by ELISA to detect anti-SMP30 antibody with recombinant SMP30 protein. Some 22 were positive and x2 two-sided tests all showed P>0.05, although it remained unclear whether there was a relationship between positive cases and clinical diagnostic data.

Fine mapping and candidate gene analysis of the dwarf gene d162(t) in rice (Oryza sativa L.)

Fan-tao Zhang,Xiao-ling Gao,Ping-rong Wang,Chang-hui Sun,Bing Wang,Xiu-lan Li,Jian-qing Zhu,Xiao-jian Deng 한국유전학회 2011 Genes & Genomics Vol.33 No.1

In our previous study, d162(t), a single recessive gene, which caused rice dwarf mutant, had been mapped on the short arm of chromosome 3. In this study, the d162(t) gene was fine mapped to a confined region about 0.82 cM by RM14641 and RM3134, and co-segregated with InDel361-2, InDel361-3,InDel361-5, RM14645, RM1022 and RM14643, where no known gene involved in plant height has been identified. Based on the annotation results of TIGR, dozens of open reading frames (ORFs) were predicted in this region, among them,five ORFs were the most possible genes related to the phenotype. In these ORFs, Os03g13010, related to U-box domain containing protein, had a 62bp segment deletion in the coding region in 162d (mutant type, MT). The results of RT-PCR showed that the transcriptional level of Os03g13010was significantly different between Shuhui162 (wild type, WT)and 162d (MT). Therefore, the gene (Os03g13010) encoding a U-box domain containing protein was considered as the candidate gene of d162(t).

Zeng-Hui Yue,Xin-Qun He,Xiao-Rong Chang,Jian-Ling Yuan,Bao-Sheng Yu,Mi Liu,Ling Fu,Liang Zhang,Li-Chao Shang 사단법인약침학회 2012 Journal of Acupuncture & Meridian Studies Vol.5 No.2

Objective: To explore the mechanism of Toll-like receptor (TLR4) inhibition in the delay of formation of atherosclerosis by herb-partition moxibustion. Method: Seventy-five rabbits were randomly assigned to one of five groups: blank, atherosclerosis (AS) model, direct moxibustion, herb-partition moxibustion, and drug treatment. With the exception of the blank group, all rabbits were given a high-fat diet in addition to immunologic injury to create the AS model. The experiments were carried out for 16 weeks, at which time the aorta was removed from each rabbit. Immunohistochemical methods were used to detect the gray level of the aortic TLR4 to observe the immunologic competence of its antigens. Fluorescent quantitative polymerase chain reaction was used to detect the expression of TLR4 messenger RNA (mRNA) in the aorta. Results: The gray-scale value of TLR4 and the TLR4 mRNA expression significantly decreased (p < 0.05) in the direct moxibustion, herb-partition moxibustion, and drug treatment groups. Furthermore, the effects of the herb-partition moxibustion and drug treatment were superior to those of the direct moxibustion. Conclusion: Herb-partition moxibustion inhibits aortic TLR4 activity and mRNA expression,showing that herb-partition moxibustion delays the formation of atherosclerosis through the inhibition of TLR4 expression.

Xiong, Wei,Li, Wen-Hui,Jiang, Yong-Xin,Liu, Shan,Ai, Yi-Qin,Liu, Rong,Chang, Li,Zhang, Ming,Wang, Xiao-Li,Bai, Han,Wang, Hong,Zheng, Rui,Tan, Jing Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.2

Background: To study the effect of parecoxib, a novel cyclooxygenase-2 selective inhibitor, on the radiation response of colorectal cancer (CRC) cells and its underlying mechanisms. Materials and Methods: Both in vitro colony formation and apoptosis assays as well as in vivo mouse xenograft experiments were used to explore the radiosensitizing effects of parecoxib in human HCT116 and HT29 CRC cells. Results: Parecoxib sensitized CRC cells to radiation in vitro with a sensitivity enhancement ratio of 1.32 for HCT116 cells and 1.15 for HT29 cells at a surviving fraction of 0.37. This effect was partially attributable to enhanced apoptosis induction by parecoxib combined with radiation, as illustrated using an in vitro apoptosis assays. Parecoxib augmented the tumor response of HCT116 xenografts to radiation, achieving growth delay more than 20 days and an enhancement factor of 1.53. In accordance with the in vitro results, parecoxib combined with radiation resulted in less proliferation and more apoptosis in tumors than radiation alone. Radiation monotherapy decreased microvessel density (MVD) and microvessel intensity (MVI), but increased the hypoxia level in xenografts. Parecoxib did not affect MVD, but it increased MVI and attenuated hypoxia. Conclusions: Parecoxib can effectively enhance radiation sensitivity in CRC cells through direct effects on tumor cells and indirect effects on tumor vasculature.

Neuron Discharge and c-Fos Expression in the Nucleus of the Solitary Tract Following Electroacupuncture at Acupoints of the Yangming Stomach Meridian of Foot

Jun-Feng He,Jie Yan,Jiang-Shan Li,Jian-Hua Liu,Chao Wang,Xiao-Rong Chang,Ya-Ting Qu 사단법인약침학회 2013 Journal of Acupuncture & Meridian Studies Vol.6 No.2

The nucleus of the solitary tract (nucleus tractus solitarii; NTS) is a primary center for both visceral afferents and somatic afferents. Previous experiments have demonstrated that the NTS is closely connected to the stomach and acupoints in the Yangming Stomach Meridian of Foot (ST Meridian). In this study, extracellular recording and immunochemistry methods were used to analyze the discharge of neurons and c-Fos protein expression in the NTS following acupuncture at different acupoints and a nonacupoint. A total of 104 discharging neurons were detected in the NTS of 52 rats, of which 86 provided complete data. After acupuncture at Sibai (ST 2), Zusanli (ST 36), Neiting (ST 44), Quanliao (SI 18), and the nonacupoint, the neuron response rate in the NTS was 65.12%, 51.16%, 46.51%, 34.88% and 31.40% respectively. For neuron response rate, there was a significant difference among Sibai (ST 2), Zusanli (ST 36), Neiting (ST 44), Quanliao (SI 18), and the nonacupoint (p < 0.01 or p < 0.05). In the other 48 rats, the number of c-Fos immunoreactive neurons in the NTS by electroacupuncture (EA) at Sibai (ST 2) group was significantly higher than that EA at other acupoints and the nonacupoint (p < 0.05 or p < 0.01). EA at both Zusanli (ST 36) and Neiting (ST 44) increased c-Fos immunoreactive neurons significantly over EA at Quanliao (SI 18) and the nonacupoint (p < 0.05 or p < 0.01), while there was no difference between EA at Quanliao (SI 18) and the nonacupoint group (p > 0.05). The experiments demonstrated that the afferent convergence in NTS are different by body surface points stimulus, which suggests that the NTS might be a primary center in the central nervous system receiving acupoints stimulus from the ST Meridian.

In order to evaluate the effects of SIMNETONG, GANGJIYOUNSOODAN and CHUNGSIMJOKITANG(Xinnao-Tong, Jiangzhiyanshou-Dan and Qingxintiaoqi-Tang) on hyperlipidemia, the experimental study was performed in rats without or with hyperlipidemia induced by 2% cholesterol fed-diet or Triton WR-1339. And the levels of serum total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol and phospholipid were measured. The results are summarized as follows : In the model of hyperlipidemia induced by 2% cholesterol Fed-diet 1. Both low & highly concentrated GANGJIYOUNSOODAN showed significantly decreasing effects on the level of serum total cholesterol while SIMNETONG & CHUNGSIMJOKlTANG didn't. 2. GANGJIYOUNSOODAN, SIMINETONG and CHUNGSIMJOKITANG showed decreasing effects on the level of serum triglyceride with no statistical significance. 3. Only highly concentrated GANGJIYOUNSOODAN showed increasing effects on the level of serum HDL-cholesterol while the others had no effects. 4. Only highly concentrated GANGJIYOUNSOODAN had decreasing effects on the level of serum LDL-cholesterol while the others had no effects. 5. Highly concentrated GANGJIYOUNSOODAN and CHUNGSIMJOKITANG showed significantly decreasing effects on the level of serum phospholipid while the other had no effects. In the model of hyperlipidemia induced by Triton WR-1339 6. SIMNETONG, GANGJIYOUNSOODAN and CHUNGSIMJOKITANG showed slightly decreasing effects on the levels of serum total cholesterol and triglyceride with no statistical significance. 7. None of SIMNETONG, GANGJIYOUNSOODAN and CHUNGSIMJOKITANG showed any effects on the level of serum HDL-cholesterol. 8. Highly concentrated GANGJIYOUNSOODAN and CHUNGSIMJOKITANG showed decreasing effects on the level of serum LDL-cholesterol but the other had no effects. 9. All of highly concentrated SIMNETONG, GANGJIYOUNSOODAN and CHUNGSIMJOKITANG showed decreasing effects on the level of serum phospholipid with statistical significance. These results show that GANGJIYOUNSOODAN and CHUNGSIMJOKITANG, in orders, have antihyperlipidemic effects. Further study on the mechanism and on the herb screening of these prescription should be followed.
