Clinical observation on prevention of chemotherapy infection in gastric cancer by moxa-stick moxibustion plus rhG-CSF and its effect on immune function / 针灸推拿医学（英文版）

Objective: To observe the effect of moxa-stick moxibustion plus recombinant human granulocyte-colony stimulating factor (rhG-CSF) in preventing chemotherapy infection in gastric cancer and its effect on immune function. Methods: A total of 70 patients with gastric cancer treated by chemotherapy were randomly divided into an observation group and a control group, with 35 cases in each group. The control group was given rhG-CSF, and the observation group was given additional moxa-stick moxibustion on the basis of rhG-CSF. Both groups were treated for 2 chemotherapy cycles, totally 6 weeks. The number of patients with infection, the duration of infection and the duration of continuous use of antibiotics were observed. The leukocytes and granulocytes counts, the levels of tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) were measured before and after treatment, and the levels of CD4, CD8 and natural killer (NK) cells were analyzed. Results: The infection rate of the observation group was significantly lower than that of the control group (P<0.05), and the duration of infection and the duration of continuous use of antibiotics were also shorter (P<0.05). After treatment, the leukocytes and granulocytes counts in the two groups were higher than those before treatment (all P<0.05). After treatment, the levels of TNF-α and IFN-γ of the patients in the two groups were improved (all P<0.05), and there were significant differences between the observation group and the control group (P<0.05). After treatment, the numbers of CD4, CD8, and NK cells in the observation group increased significantly (all P<0.05), but the changes in the control group were not significant (P>0.05). Conclusion: Moxa-stick moxibustion plus rhG-CSF can significantly reduce the incidence and severity of chemotherapy infection in gastric cancer, increase the leukocytes and granulocytes counts, and regulate the levels of inflammatory factors, which may be related to the improvement of the immune function of the patients.

Screening of monomers from traditional Chinese medicine for specifically inhibiting brafV600E CT26 cells / 中国药理学通报

Aim: To screen BRAFV600E CT26 cell inhibitors from monomers of traditional Chinese medicine (TCM). Methods CT26 cell line was constructed with lentivirus plasmid to stably express BRAFV6C0E. The proliferation, migration and expression of related proteins in MEK/ERK signaling pathway were detected. The monomers of TCM were detected for biological activities as potential BRAF inhibitors by Discovery Studio 4. 0, and further evaluated by MTT assay. Results: The proliferation and migration of BRAFV6C0E CT26 cells were obviously strengthened compared with wild type control. The expressions of proteins in MEK/ ERK pathway were also activated in BRAFV6C0E CT26 cells. Compared with wild type control, Aloin, Angoroside C and Cyasterone exhibited the potent effect against BRAFV600E in CT26 cells (P <0. 05), and could down-regulate the expression of BRAFV600E. Conclusion: Aloin, Angoroside C, Cyasterone might be the potent inhibitors against BRAF for colon treatment.

Compound Tufuling Granules (characters: see text) regulate glucose transporter 9 expression in kidney to influence serum uric acid level in hyperuricemia mice / 中国结合医学杂志

<p><b>OBJECTIVE</b>To explore the effect of Compound Tufuling Granules ([characters: see text], CTG) on regulating glucose transporter 9 (GLUT9) expression in the kidney to influence the uric acid excretion by the kidney and serum uric acid (SUA) level in hyperuricemia mice.</p><p><b>METHODS</b>Sixty Kunming male mice were randomly divided into the control group, model group, benzbromarone group, and CTG high-, middle- and low-dose groups. The yeast extract and uricase inhibition method were used to build hyperuricemia model, and the corresponding drugs were administrated on the 7th day. On the 21st day the 24-h urine was collected, on the 22nd day the blood was collected, the SUA level was detected by uricase colorimetry, and the mRNA and protein expressions of GLUT9 were detected by quantitative real-time polymerase chain reaction and Western blot, respectively.</p><p><b>RESULTS</b>Compared with the model group, the levels of SUA and the mRNA and protein expressions of GLUT9 were significantly decreased, and the fraction excretion of uric acid (FEUA) was significantly increased in the CTG groups and benzbromarone group (all P<0.05). There was no significant difference in the above indicators between the CTG high-dose group and benzbromarone group (P>0.05). SUA is positively related to the GLUT9 mRNA and protein expressions in the kidney (P<0.05 or P<0.01).</p><p><b>CONCLUSIONS</b>CTG can significantly reduce the SUA and increase the FEUA. In addition, CTG can effectively inhibit the mRNA and protein expressions of GLUT9 in the kidney of hyperuricemia mice to inhibit the uric acid re-absorption, promote uric acid excretion and reduce SUA.</p>

Inhibitory effects of propofol on supraoptic nucleus neurons of rat hypothalamus in vitro / 生理学报

To investigate the effects of novel intravenous general anesthetic propofol on membrane electrophysiological characteristics and action potential (AP) of the supraoptic nucleus (SON) neurons and possible ionic mechanisms, intracellular recordings were conducted in SON neurons from the coronal hypothalamic slice preparation of adult male Sprague Dawley (SD) rats. The results showed that bath application of 0.1 mmol/L propofol induced a significant decline in resting potential (P < 0.01), and higher concentrations of propofol (0.3 and 1.0 mmol/L) decreased time constant and slope resistance of cell membrane (P < 0.01). Under the hyperpolarizing current pulses exceeding 0.5 nA, an anomalous rectification was induced by hyperpolarization-activated cation channel (I(h) channel) in 11 out of 18 tested SON neurons. Bath of propofol reversibly decreased the anomalous rectification. Moreover, 0.1 mmol/L propofol elevated threshold level (P < 0.01) and decreased Max L. slope (P < 0.05) of the spike potential in SON neurons. Interestingly, 0.3 and 1.0 mmol/L propofol nullified APs in 6% (1/18) and 71% (12/17) tested SON neurons, respectively. In the SON neurons where APs were not nullified, propofol (0.3 mmol/L) decreased the amplitude of spike potential (P < 0.05). The higher concentrations of propofol (0.3 and 1.0 mmol/L) decreased firing frequencies evoked by depolarizing current pulses (0.1-0.7 nA), and shifted the current intensity-firing frequency relation curves downward and to the right. These results suggest that propofol decreases the excitability of SON neurons by inhibiting I(h) and sodium channels.
