OBJECTIVETo observe the law of the meridian abnormal changes and the correlation with acupuncture efficacy based on the effectiveness study of electroacupuncture (EA) in treatment of severe functional constipation.

METHODSSeventy patients of severe functional constipation were randomized into an EA group and a sham-EA group, 35 cases in each one. In the EA group, Tianshu (ST 25) and Fujie (SP 14) were punctured deeply and stimulated with EA (dense-disperse wave, 2Hz/15 Hz, 0. 1 to 1. 0 mA), and Shangjuxu (ST 37) was needled. In the sham-EA group, the sites lateral to Tianshu (ST 25) and Fujie (SP 14) were punctured shallowly and stimulated with electricity. The site lateral to Shangjuxu (ST 37) was punctured shallowly. The treatment was given continuously for 8 weeks in the two groups, 5 times weekly in the first 2 weeks and 3 times weekly in the rest 6 weeks. WANG Juyi's meridian examination method was applied to detect the abnormalities of the spleen, stomach and large intestine meridians before treatment, and in 2, 4, 6 and 8 weeks among 70 patients separately. The frequency of complete spontaneous bowel movement (CSBM) every two weeks, meridian abnormal value and the relativity with CSBM change rate were compared in the patients between two groups.

RESULTSRegarding the increase of CSBM frequency, the effect started since the 2nd week in the EA group, with the treatment going on, CSBM frequency was increased apparently (all P<0. 05). In the sham-EA group, after 6 and 8-weeks of treatment, CSBM frequency was increased apparently as compared with that before treatment (all P<0. 05). The increase of CSBM frequency in the EA group was remarkably as compared with the sham-EA group at every time point (all P<0. 05). The abnormal value of the large intestine meridian in 2 weeks of treatment and the values of the stomach and spleen meridians and the relevant meridians in 4 weeks of treatment were all reduced apparently as compared with those in the baseline in the EA group (all P<0. 05). With the treatment time going on, the abnormal reflections on the large intestine and stomach meridians were reduced gradually (all P<0. 05), and the total change rate of abnormalities on the large intestine, stomach and spleen meridians presented the negative correlation with the total change rate of CSBM frequency (P<0. 01, P<0. 05).

CONCLUSIONIn the EA group, the efficacy on CSBM frequency in severe functional constipation is advantageous and stable as compared with the sham-EA group. Acupuncture at the relevant acupoints of the spleen, stomach and large intestine meridians achieves the definite regulation to the meridian abnormalities. It is discovered that the abnormal changes in the spleen, stomach

Objective To investigate the effect of compound Fufangteng mixture-containing serum on the proliferation of bone marrow mesenchymal stem cell (BMSC) and its mechanism. Methods Rat BMSC were isolated, cultured and purified in vitro by direct adherence method. Cell morphology was observed. Surface markers were identified by flow cytometry. The rats were treated with compound Fufangteng mixture at a dose of 3 mL/(kg·d) by gavage for 14 d, and then the drug-containing serum was collected. BMSC were divided into the blank control group, drug-containing serum group, Notch1 small interfering ribonucleic acid (siRNA) group and Notch1 siRNA+drug-containing serum group. The proliferation rate of BMSC was detected and the relative expression levels of Notch1 signaling pathway-associated messenger ribonucleic acid (mRNA) and proteins were measured in each group. Results Microscopic observation showed that the first generation BMSC were seen in the long spindle shape, and grown in the parallel or spiral pattern. The third generation BMSC positively expressed CD90 and CD44, whereas were negative for CD45. Compared with the blank control group, the proliferation rate of BMSC in the drug-containing serum group and Notch1 siRNA+ drug-containing serum group was significantly increased, whereas that of BMSC was significantly decreased in the Notch1 siRNA group (all P < 0.05). Compared with the Notch1 siRNA group, the proliferation rate of BMSC was significantly increased in the Notch1 siRNA+drug-containing serum group (P < 0.05). Compared with the blank control group, the relative expression levels of Hey1 and Delta-like ligand (DLL)1 mRNA and proteins were significantly up-regulated in the drug-containing serum group, whereas those were significantly down-regulated in the Notch1 siRNA group and Notch1 siRNA+drug-containing serum group (all P < 0.05). Compared with the Notch1 siRNA group, the relative expression levels of Hey1 and DLL1 mRNA and proteins were significantly up-regulated in the Notch1 siRNA+drug-containing serum group (all P < 0.05). Conclusions Compound Fufangteng mixture-containing serum may promote the proliferation of rat BMSC, and its mechanism is probably associated with the activation of Notch1 signaling pathway.

Objective To use ultrasonic cardiac output monitor(USCOM)to monitor the hemodynamics of children who un-derwent congenital heart disease(CHD)surgery before and after fluid therapy,and to examine the accuracy of the hemodynamic parameters central venous pressure(CVP),stroke volume variation(SVV),corrected flow time(FTc)and smith madigan inotro-py index(SMII)in predicting fluid responsiveness of children post operation.Methods USCOM was used to monitor the hemo-dynamic parameters of post-operative children before and after fluid therapy.The change of SVI(ΔSVI)was calculated based on the stroke volume index(SVI)before and after fluid therapy,and the inotropic scores(IS)were obtained based on the doses of in-otropic drugs used.Children with ΔSVI≥ 15% were defined to be responders who responded to fluid resuscitation and those with ΔSVI < 15% as non-responders.Two subgroups were also established in terms of IS:IS ≤ 10 group and IS > 10 group.Results Among the parameters(CVP,FTc and SM,etc.),only the area under the ROC curve(AUC)of SVV was signifi-cantly different between before and after fluid therapy(AUC 0.776,P < 0.01).Subgrouping analysis also showed significant difference in only the AUC of SVV between IS≤ 10 group and IS> 10 group(AUC:0.732,P =0.045 or 0.813,P =0.002). Conclusion SVV monitored by USCOM,in contrast to CVP,FTc and SMII,can predict the fluid responsiveness in children af-ter congenital heart surgery.Prediction of fluid responsiveness by SVV shows higher accuracy in IS>10 group than in IS≤10 group.

Islet transplantation is one of the effective therapies for diabetes mellitus. Nevertheless, multiple issues still exist, such as shortage of donors and adverse reactions caused by long-term use of immunosuppressants, which limit the islet survival post-transplantation. Microencapsulated islet transplantation may overcome these difficulties to certain extent, whereas many factors, such as the destruction of immune isolation microenvironment within the microcapsules and insufficient supply of oxygen and nutrients, constrain the application of microencapsulated islet transplantation in clinical practice. In recent years, how to enhance the effect of microencapsulated islet transplantation has been gradually studied. The application of stem cells in microencapsulated islet transplantation has steadily become a research hot spot. Therefore, the optimizing strategies for microencapsulated islet transplantation and the application of stem cells in microencapsulated islet transplantation were reviewed, and the potential improvement techniques of microencapsulated islet transplantation were investigated in this article, aiming to provide reference for further clinical application of microencapsulated islet transplantation.

Objective To evaluate the effect of mesenchymal stem cell (MSC) coated-islets on instant blood-mediated inflammatory reaction (IBMIR) after islet transplantation. Methods MSC labeled with tracer and human islets were placed into an ultra-low adsorption cell culture dish, shaken and mixed twice at an interval of 0.5 h, and then incubated at 37 ℃ and 5% CO₂ for 24 h to obtain MSC-coated islets. The coating effect of MSC and in vitro function of the islets were assessed. A blood circulation tube-shaped model was established in vitro. In the blank control group, 0.2 mL of islet culture solution was added. In the islet group, 800 islet equivalent quantity (IEQ) of uncoated islets were supplemented. In the MSC-coated islets group, 800 IEQ of MSC-coated islets were added, and circulated for 60 min at 37 ℃. A portion of 0.5 mL blood sample was taken for routine blood test at 0, 30 and 60 min, respectively. After 60 min circulation, the blood sample was filtered with a 70 μm filter to collect plasma, blood clots and islets. Blood clots and islets were subject to hematoxylin-eosin (HE) staining and immunohistochemical staining. Morphological changes and the aggregation of CD11b-positive cells surrounding the islets were observed. The contents of plasma thrombin-antithrombin complex (TAT), tissue factor (TF), C3a, C5b-9, interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, monocyte chemoattractant protein (MCP)-1 and IL-8 were determined by enzyme-linked immune absorbent assay. Results After 24 h co-incubation, the islets were coated by MSC, with a coating degree of approximately 80%. In the islet and MSC-coated islet group, a large quantity of neutrophils and monocytes were observed surrounding the blood clots and islets, and the quantity of CD11b-positive cells in the MSC-coated islet group was less compared with that in the islet group. After co-incubation with the whole blood for 0, 30 and 60 min, the quantity of platelets, neutrophils and monocytes was declined in the MSC-coated and islet groups, and gradually decreased over time. Compared with the blank control group, the quantity of platelets, monocytes and neutrophils was lower, whereas the TF content was higher in the MSC-coated islet group. Compared with the islet group, the quantity of platelets, monocytes and neutrophils was higher, whereas the TAT and TF contents were less in the MSC-coated islet group, the differences were statistically significant (all P < 0.05). Compared with the blank control group, the expression levels of C3a, C5b-9, IL-6, TNF-α and IL-8 were up-regulated in the MSC-coated islet group. Compared with the islet group, the expression levels of C3a, C5b-9, IL-1β, IL-6, TNF-α, IL-8 and MCP-1 were down-regulated in the MSC-coated islet group, and the differences were statistically significant (all P < 0.05). Conclusions MSC-coated islets may reduce the exposure of islet TF in the blood and prevent the incidence of IBMIR during the coagulation response stage, thereby mitigating the injury and loss of islet allograft in the early stage of islet transplantation.
