Small for gestational age ( SGA ),one of the major adverse pregnancy outcomes, significantly increases the risk of perinatal death and metabolic diseases in adulthood. It is of great significance to strengthen early surveillance and intervention for SGA prevention. Dyslipidemia during pregnancy, as a common metabolic disorder, has been considered to correlate with the increased risk of SGA; however, the epidemiological evidence is still controversial. We have systematically reviewed the recent studies related to the association between serum lipid level during pregnancy and the risk of SGA, so as to provide reference for prevention and intervention of SGA.

Anaerobic ammonium oxidation (ANAMMOX), as its essential advantages of high efficiency and low cost, is a promising novel biological nitrogen elimination process with attractive application prospects. Over the past two decades, many processes based on the ANAMMOX reaction have been continuously studied and applied to practical engineering, with the perspective of reaching 100 full-scale installations in operation worldwide by 2014. Our review summarizes various forms of ANAMMOX processes, including partial nitritation-ANAMMOX, completely autotrophic nitrogen removal over nitrite, oxygen limited autotrophic nitrification and denitrification, denitrifying ammonium oxidation, aerobic deammonification, simultaneous partial nitrification, ANAMMOX and denitrification, single-stage nitrogen removal using ANAMMOX and partial nitritation. We also compare the operating conditions for one-stage and two-stage processes and summarize the obstacles and countermeasures in engineering application of ANAMMOX systems, such as moving bed biofilm reactor, sequencing batch reactor and granular sludge reactor. Finally, we discuss the future research and application direction, which should focus on the optimization of operating conditions and applicability of the process to the actual wastewater, especially on automated control and the impact of special wastewater composition on process performance.

Objective To investigate whether cotransplant with xenogenetic neonatal porcine Sertoli cells (NPSCs) could prolong rat islet allograft survival and its mechanisms.Methods 1500 islets equivalent quantity (IEQ) and 1×10~7 NPSCs were implanted under renal capsule of diabetic Wistar rats.Islets implanted alone were used as control group (n=6);islets co-transplanted with NPSCs under left renal capsule of recipients served as experimental group (n=6);meanwhile,islets and NPSCs implanted into the different sides of kidneys were used as another control grouP(n=4).Blood glucose level was measured everyday.The graft-bearing kidneys at the time of rejection were Results Co-transplantation with NPSCs to the same site significantly prolonged islet allograft survival (mean survive time,16.3±1.4 days vs.5.7±1.0 days in islet transplant alone control group,P<0.05).In contrast,transplantation with NPSCs and islets separately did not prolong the islet allograft survival (5.3±0.5 days).HE staining showed plenty of local infiltrated lymphocytes in the transplanted site of the eontrol group.which were demonstrated as mainly CD3+ T cells by immunopathology.The local expression of Bcl-2 was markedly elevated in co-transplantation group as compared with the other 2 groups,while there were no significant differences in the HO-1 expression among these groups.Conclusion Co-transplantation with xenogenic NPSCs can significantly prolong islet allograft survival in rats.The immunoprotective mechanism may be associateel with the inhibition of lymphocyte infiltration and the enhancement of the local expression of protective gene Bcl-2.

OBJECTIVETo compare the clinical efficacy in the treatment of post-stroke shoulder-hand syndrome between floating-needle therapy and conventional acupuncture on the basis of rehabilitation training.

METHODSOne hundred cases of post-stroke shoulder-hand syndrome were randomized into a floating-needle group and an acupuncture group, 50 cases in each one. The passive and positive rehabilitation training was adopted in the two groups. Additionally, in the floating-needle group, the floating-needle therapy was used. The needle was inserted at the site 5 to 10 cm away from myofasical trigger point (MTrP), manipulated and scattered subcutaneously, for 2 min continuously. In the acupuncture group, the conventional acupuncture was applied at Jianqian (EX-UE), Jianyu (LI 15), Jianliao (TE 14), etc. The treatment was given once every two days, 3 times a week, and 14 days of treatment were required. The shoulder hand syndrome scale (SHSS), the short form McGill pain scale (SF-MPQ) and the modified Fugl-Meyer motor function scale (FMA) were used to evaluate the damage severity, pain and motor function of the upper limbs before and after treatment in the two groups. The clinical efficacy was compared between the two groups.

RESULTSSHSS score, SF-MPQ score and FMA score were improved significantly after treatment in the two groups (all P < 0.01), and the improvements in the floating-needle group were superior to those in the acupuncture group (all P < 0.05). The total effective rate was 94.0% (47/50) in the floating-needle group, which was better than 90.0% (45/50) in the acupuncture group (P < 0.05).

CONCLUSIONThe floating-needle therapy combined with rehabilitation training achieves a satisfactory efficacy on post-stroke shoulder-hand syndrome, which is better than the combined therapy of conventional acupuncture and rehabilitation training.
