OBJECTIVETo assess the effects of moxibustion at Shenque (CV8) in promoting gastrointestinal function recovery in rats following gastric perforation repair and explore the underlying mechanism.
METHODSThirty male SD rats with glacial acetic acid-induced gastric perforation underwent surgical repair of the perforation. The rats were then randomized 8 days later into model group (n=10), domperidone group (n=10), and moxibustion group(n=10) and treated with physiologic saline, domperidone suspension, and moxibustion at Shenque (CV8), respectively. Gastric antral myoelectric activities of the rats were observed and peripheral blood levels of TNF-α, IL-6, and T lymphocyte subpopulation were determined.
RESULTSGastric antral myoelectric activities in rats receiving moxibustion were stronger than those in the model group (P<0.05) but comparable with those in domperidone group (P>0.05). TNF-α and IL-6 level were decreased significantly and T lymphocyte subpopulations increased significantly in moxibustion group compared with those in the model and domperidone groups (P<0.05).
CONCLUSIONMoxibustion at Shenque (CV8) can promote the recovery of gastrointestinal functions in rats undergoing gastric perforation repair possibly by enhancing gastrointestinal electric activity, suppressing inflammation, and improving the cellular immune function, and can therefore serve as a simple and effective adjuvant therapy during the perioperative period.

OBJECTIVETo investigate the difference of postoperative drainage and systemic trauma response between endoscopic and traditional near total thyroidectomy to provide the basis for selecting appropriate operative methods.
METHODSIn this prospective clinical controlled study, 80 patientsscheduled for near total bilateral thyroidectomy for the first time were divided equally into endoscopic surgery group (group A) and open surgery group (group B). The total drainage volume after operation, postoperative extubation time, and postoperative daily drainage volume were recorded after the operation. The contents of triglyceride (TG) and total protein (TP) were determined in the postoperative drainage fluid onthe first day. The levels of interleukin 6 (IL6), high sensitive C reactive protein (HSCRP), alpha 1 acid glycoprotein (AAG), ceruloplasmin (CER) and haptoglobin (HPT) in venous blood were tested before the operation and on the first day after surgery.
RESULTSCompared with those in group B, the postoperative drainage volumein group Aincreased significantly (P=0.000) and the postoperative extubation time was significantly prolonged (P=0.000); the mean postoperative daily drainage volume was significantly larger ingroup A than in group B (P=0.000) and tended to decrease with time in both groups. There was no significant difference in the content of triglycerideortotal protein in the drainage fluid between the two groups on the first day after operation (P=0.429 and 0.324, respectively). In both groups, the contents of AAG, ceruloplasmin and haptoglobin on the first postoperative day were all similar with those measurement before operation (P>0.05), but significant variations occurred in the levels of IL6 and HSCRP on the first postoperative day (P=0.000). The serum levels of IL?6 or HS?CRP did not differ significantly between the two groups on the first day after operation (P=0.054 and 0.066, respectively).
CONCLUSIONCompared with open surgery, endoscopic near total bilateral thyroidectomyis associated with an increased the volume of postoperative drainage and a prolonged time of extubationbut not an increased systemic trauma response. Therefore, endoscopic surgery can serve as one of the routine options for patients who are concerned with neckscars resulting from open surgeries.

This study was to establish the episomal vector reprogramming method to reprogram iPSC from human cord blood (CB) CD34(+) cells. The non-integrating plasmids of pEB-C5 and pEB-Tg were transfected into short-term cultured CB CD34(+) cells by using the nucleofector, so as to demonstrate efficient reprogramming of CB CD34(+) cells. Within 14 days of one-time transfection by two plasmids together, up to 200 iPSC-like colonies per 2 million transfected CB CD34(+) cells were generated. The results showed that the pluripotency of iPSC-derived CB CD34(+) cells was similar to that of hESC and the karyotypes of iPSC were normal. In addition, no vector integration was found in iPSC of 9th and 10th passages. Furthermore, hiPSC formed teratoma with three embryonic germ layers. It is concluded that the integration-free method to generate human iPSC from CB CD34(+) cells is reliable and can provide new ways for both research and future clinical applications.

OBJECTIVETo evaluate the effect of water pollution with dexamethasone on intestinal flora in mice.
METHODSTwenty Balb/c mice were randomly divided into control group and low-, moderate- and high-dose dexamethasone groups. The mice in dexamethasone groups were exposed to dexamethasone sodium phosphate in drinking water at doses of 0.035, 0.225, and 2.25 ng for 36 days. The changes in behaviors, fur condition, and feces of the mice were observed daily. All the mice were sacrificed at 36 days and the tissues in the ileocecal region was collected for denaturant gradient gel electrophoresis (DGGE) of 16S rDNA V6 variable regions of microbes and sequence analysis with BLAST.
RESULTSThe mice in the 3 dexamethasone groups all showed aggressive behaviors. Cluster analysis of DGGE graph showed relatively stable floras in the ileocecal region in all the mice, but principal component analysis identified differences in the dominating flora among the groups. Diversity analysis of the flora revealed significantly increased amount and types of bacteria in the intestinal flora in all the 3 dexamethasone groups (P<0.05 or 0.01) compared with the control group. Sequence analysis of 16S rDNA V6 regions showed 15 common bacterial species and 2 differential species between the dexamethasone groups and the control group with changes in the type and proportion of the dominating bacterium in the dexamethasone groups. Lactobacillus colonization was detected in the control group but not in moderate- and high-dose dexamethasone groups, and Shigella species were found in the latter two groups.
CONCLUSIONSWater contamination with dexamethasone can affect the nervous system of mice, cause changes in the types and amounts of intestinal bacteria and the dominating bacteria, and inhibit the colonization of probiotics in the intestinal floras to increase the risk of invasion by intestinal pathogenic bacteria.

To approach the effect of CCAAT/enhancer binding proteins (C/EBPs) on un-terminal differentiation of HL-60 cells after treatment with Arsenic Trioxide ( As_2O_3) . Methods The changes of cell morphology were observed by Wright staining, the alteration in the cell proliferation was determined by WST1 experiment and the NBT reduction assay was used to detect the differentiation condition of cells, determination and analysis cell cycle. The expressions of C/EBP? and C/EBP? mRNA in HL-60 cells exposed to ATRA and As_2O_3 were assayed by semi-quantitative RT-PCR. Results It was found that ATRA could up- regulate the mRNA expression of C/EBP? obviously, but down-regulate the mRNA expression of C/EBP?. As_2O_3 could up-regulate the mRNA expression of C/EBP? lightly, down-regulate the expression of C/EBP?. Conclusion Both of ATRA and As_2O_3 can down-regulate the mRNA expression of C/EBP?,but there is no significant difference between these two groups,ATRA and As2O3 can up- regulate the mRNA expression of C/EBP?, with significant differences (P

Myelodysplastic syndromes (MDS) are a group of bone marrow failure diseases. The bone marrow microenvironment consists of bone marrow stromal cells (BMSC), growth factors and cytokines. The BMSC supporting haemopoiesis include mesenchymal stem cells (MSC), osteoblasts, endothelial cells and macrophages, but the adipocytes play a role in the suppression of hematopoiesis. Recently more and more researches indicate that the abnormality of bone marrow microenvironment involves in the pathogenesis and progression of MDS. In this review the abnormality of MDS bone marrow microenvironment is summarized briefly.

OBJECTIVETo survey the prevalence of high-risk human papillomavirus (HPV) in woman in Guangzhou during the period from 2013 to 2014.
METHODSA total of 2501 women in Guangzhou seeking medical attention in our hospital underwent high-risk HPV genotype screening of cervical specimens using real-time PCR.
RESULTSThe prevalence of high-risk HPV infection among the women was 14.85% (146/983) in the year 2013, similar to the rate of 14.56% (221/1518) in 2014 (Χ(2)=0.041, P=0.839); no significant differences were found in the high-risk HPV infection rates between different age groups in either 2013 (Χ(2)=2.916, P=0.572) or 2014 (Χ(2)=6.494, P=0.165). The constituent ratio of the 13 types of high-risk HPV showed no significant difference between 2013 and 2014 (Χ(2)=11.872, P=0.452). The 13 HPV genotypes detected, listed in a descending order of the constituent ratios, included HPV-52, -16, -58, -56, -39, -51, -68, -59, -31, -35, -18, -33 and -45 in 2013, and were HPV-52, -16, -58, -68, -18, -51, -56, -39, -31, -33, -59, -35 and-45 in 2014.
CONCLUSIONWe report a high prevalence of high-risk HPV among women in Guangzhou, which suggests the necessity of screening for high-risk HPV-DNA among women at all ages for prevention and early detection of cervical cancer.
