Based on the thought of Zhishen (a kind of mind regulation), Professor SHI Xue-min, academician of the China Academy of Engineering, found the Xingnao Kaiqiao (to refresh the mind and to cause resuscitation) acupuncture method, which still plays an important role in the acupuncture treatment of wind stroke nowadays. Meanwhile, great importance is attached to the comprehensive treatment of wind stroke. Danqi Piantan capsule (see text) is developed and "wind stroke unit" is set up. In recent years, Professor SHI shifts the center of research to the treatment of hypertension, the risk factor of wind stroke. Taking Renying (ST 9) as the major acupoint, acupuncture with standard measurement and manipulations is established. And good clinical effect has been obtained as well. Therefore, this article focuses on the introduction of Professor SHI Xue-min's contribution to wind stroke treatment.

ObjectiveTo study the state of oxidative injury induced by sodium arsenite(NaAsO2) in SV-40-immortalized normal uroepithelial (SV-HUC-1 ) cells.Methods SV-HUC-1 cells were exposed to different concentrations of NaAsO2[0(control),1,2,4,8,10 μmol/L] for 24 h,intracellular reactive oxygen species (ROS) was determined by flow cytometry,and the content ofintracellular nitrotyrosine(NT) and the 8-Hydroxydeoxyguanosine (8-OHdG) levels of cell culture medium were detected by enzyme linked immunosorbent assay (ELISA).Results After 24 h treatment,ROS levels(81.76 ± 4.91,95.23 ± 2.17,126.61 ± 17.95,126.74 ± 27.77,114.18 ± 9.65) of SV-HUC-1 cells in the 1,2,4,8,10 μmol/L NaAsO2 exposure groups were significantly higher than those of the control group (69.84 ± 1.28,P ＜ 0.05 or ＜ 0.01 ),ROS levels and exposure dose were positively correlated significantly(r =0.818,P＜ 0.01); the content of NT in the 10 μmol/L NaAsO2 exposure group[(919.66 ± 206.33) μg/L] was significantly higher than that in the control group[ (238.19 ± 38.28)μg/L,P ＜ 0.01 ],NT content and dye concentrations of arsenic also had dose-response relationship (r =0.617,P ＜ 0.01); after 24 h the cells were treated with arsenic,no significant difference of 8-OHdG content in the culture medium was observed(F =2.127,P ＞ 0.05 ).ConclusionNaAsO2 can cause SV-HUC-1 cell oxidative damage.

OBJECTIVETo study the dynamic changes of capillaries and inflammatory cells in different regions of brain in rat with middle cerebral artery obstruction (MCAO), and the effects of acupuncture in different frequencies on them.

METHODSIn reference to Zea-Longa's method, rat model of MCAO was established by thread-ligation. Shuigou point (DU26), the main acupoint for "awakening brain and opening apertures", was stimulated by high (180 times/s) or low (60 times/s) frequency puncturing 5 s every 12 h for 6 times totally. The amount of capillaries (AC) and inflammatory cells (AIC) in brain cortex (BC), hippocampus (Hp) and corpus striatum (CS) was counted.

RESULTSChanges in AC and AIC of all brain regions (except for CS) in rats immediately after modeling were statistically insignificant (P > 0.05). But 72 h later, AC in CS decreased, AC in Hp, AIC in BC and AIC in Hp increased significantly in the modeled rats, showing significant difference to the normal level, but AIC reduced to approach the normal. As compared with the rats un-intervened, AIC in BC and Hp was decreased in rats intervened with high frequency puncturing, AC and AIC in CS were increased in rats intervened by slow frequency puncturing (both P < 0.05).

CONCLUSIONAmount of capillaries and inflammation cells are changed dynamically in MCAO rats after brain ischemia, showing evident brain regional specificity; the ischemic improving effects of acupuncture in different frequencies are various in their action rings, also showing brain regional specificity.

Objective To investigate the change of high mobility group box 1 ( HMGBI ) after intestine ischemia reperfusion (I/R) in rats, compare the effect of drainage of intestine lymph fluid on gut barrier, and ex- plore the possible mechanism of iachemia-reporfusion injury. Methods Thirty-two Sprague-Dawley (SD) rats (SPF grade) were randomly divided into4 groups with 8 rats in each group: blank group, sham group, intestine is-chemia-reperfusion (I/R) group, and intestine ischemia-reperfusion with drainage of intestine lymph fluid (I/R +drainage) group. Indicators of gut barrier function damage, translocation of endotoxin, and change of HMGB1 and cytokines were detected after intestine ischemia-reperfusion injury. Results The gut barrier function damage and levels of endotoxin, HMGBI, tumour necrosis factor-alpha ( TNF-α), interleukin-6 ( IL-6 ), interleukin-1 beta (IL-1β), and soluble intercellular adhesion molecule-1 (sICAM-1) were significantly lower in blank group and sham group than in I/R group and I/R + drainage group ( P < 0. 05 ). Compared with the intestine I/R + drainage group, the levels of endotoxin and cytokines were significantly higher in the intestine I/R group. The level of HMGB1 was slightly higher than that in the intestine I/R + drainage group, but such difference was not statistically significant ( P > 0. 05 ). lmmunohistochemical staining also revealed that the expression of HMGB1 was significant- ly higher in I/R group than in I/R + drainage group. Conclusions Intestine iachemia-reperfusion injury can lead to the injury of intestine mucosal barrier and increase HMGB1 level HMGB1 may deteriorate gut barrier function and increase the leveh of systemic cytokines. Drainage of lymph fluid can block the gut-lymph pathway and thus decrease the levels of endotoxin and cytokines in systemic circulation and attenuate intestine ischemia-reperfusion injury.

It is the objective of this paper to study pharmacokinetics-pharmacodynamics (PK-PD) characteristics of ginsenoside Rg1 and Rb1 on the effect of inducing nitric oxide (NO) release after intravenous administration of Shengmai injection to rats with myocardial ischemia. The model of myocardial ischemia rats was produced by subcutaneous injection of isoproterenol. The serum samples were collected at different time points after intravenous administration of Shengmai injection to rats with the dose of 10.8 mL x kg(-1). The concentrations of ginsenoside Rg1 and Rb1 in serum were determined, and then the concentration-time curves were drawn. Pharmacokinetic parameters of ginsenoside Rg1 and Rb1 were calculated after the construction of pharmacokinetic models. Meanwhile, NO2- and NO3-, the metabolites of NO, in serum were determined, and then the effect-time curve was drawn. The combined PK-PD model was established based on the theory of effect compartment by Sheiner et al. Then pharmacodynamic parameters were calculated. The results indicated that the pharmacokinetics of ginsenoside Rg1 and Rb1 conformed to a two-compartment model. Ginsenoside Rg1 and Rb1 exhibited quick and slow elimination in rats respectively. The effect of Shengmai injection on inducing NO release did not relate directly with and lagged behind the concentrations of ginsenoside Rg1 and Rb1 in serum. The effect exhibited good correlation with ginsenoside Rg1 and Rb1 levels in effect compartment. The relationship between effect and serum concentration fits Sigmoid-E(max) model. This study successfully established the combined PK-PD model of ginsenoside Rg1 and Rb1 after intravenous administration of Shengmai injection to rats. The model can efficiently predict the concentration and effect of Shengmai injection in vivo.

Methods One hundred and twenty-nine elderly patients with CAD documented by coronary angiogram and 48 elderly patients with normal coronary angiographic results were included in this study. Plasma homocysteine level were measured by fluorescence polarization immunoassay (FPIA) method and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used to analyse the MTHFR A1298C and MS A2756G genotypes. Results The plasma homocysteine level was significantly higher in CAD group than that in the control group〔(16.2?8.6) ?mol/L vs (12.7?5.0) ?mol/L,P0.05);the prevalence of MTHFR 1298CC homozygous in the CAD patients was significantly less than that in the control group (3.1% vs 14.6%, P

Objective To investigate the clinical features, diagnosis and treatments of pelvic abscess with endometriosis. Methods A retrospective analysis was performed on 129 cases of pelvic abscess in Peking Union Medical College Hospital from January 2000 to January 2016. Among them, 34 women with endometriosis were divided into the study group and the others were in the control group. The clinical characteristics, therapeutic regimens and outcomes were compared. Results (1) General conditions:there were no statistic differences between the two groups in age, WBC, serum CA125, intrauterine device in use, pelvic inflammatory disease history;while incidence rates of dysmenorrhea (65%, 22/34) and infertility (21%, 7/34) in the study group were higher than those in the control group (all P<0.05). (2) Clinical manifestations:fever, abdominal pain and pelvic mass were the main symptoms in two groups. The incidence rates of septic shock were 12%(4/34) in the study group and 2%(2/95) in the control group (P<0.05). (3) Treatment:treatment with puncture all failed in the study group (7/7) and surgeries were required. In contrast, there was only 1/19 treatment failure with puncture in the control group. The puncture failure rates were statistically significant (P<0.05). Compared with the study group and the control group, there were significant differences (P<0.05) in the operation time of laparoscopic surgery [(76±41) versus (53±21) minutes] and of laparotomy [(168±58) versus (116±35) minutes], intra-operative blood loss of laparoscopic surgery [(216±296) versus (43±36) ml] and of laparotomy [(448 ± 431) versus (145 ± 24) ml]. Conclusions Pelvic abscess in women with endometriosis is more severe and refractory to antibiotics and puncture treatment. Active surgical intervention is required. Although surgical procedures are often difficult, prognosis is comparatively satisfied.

Due to the low effectiveness of traditional assisted reproductive technology (ART), new technological possibilities are constantly explored. Lots of studies have demonstrated the potential of microfluidics to revolutionize the fundamental processes of in vitro fertilization (IVF). With the advantages of high efficiency, short time, harmless collection, real-time observation of separation, similar microenvironment, and automation, the application of microfluidics in sperm isolation and IVF has shown an evident superiority over the conventional approaches and provided a new platform for ART. This review highlights the application of various microfluidic techniques in sperm motility assessment and isolation, sperm chemotaxis assay, IVF, sperm concentration, and sperm separation and enrichment in recent years. It also briefly introduces the basic principles, structural design, and operation processes of the microfluidic platform, focusing on the advantages and disadvantages of each method and the potential of their clinical application. Obviously, there are still some challenges to the application of microfluidics in ART. However, it is believed that the development of this new technology would be toward a highly integrated application of several steps in one single device, known as IVF-lab-on-a-chip.
