Abstract
Respiration variation in arterial pulse pressure (ΔPP) and pulse oximetry plethysmographic waveform amplitude (ΔPOP) are accurate predictors of fluid responsiveness in mechanically ventilated patients. We hypothesized that stroke volume variation (SVV) and pleth variability index (PVI) can predict fluid responsiveness in mechanically ventilated patients during major surgical procedures in Hans Chinese. This prospective study consisted of fifty-five Hans Chinese patients undergoing resection of primary retroperitoneal tumors (PRPT). During the surgical procedures, hemodynamic data [central venous pressure (CVP), cardiac index (CI), stroke volume index (SVI), SVV, and PVI] were recorded before and after volume expansion (VE) (8 ml•kg-1 of 6% hydroxyethyl starch 130/0.4). Fluid responsiveness was defined as an increase in SVI ≥ 10% after VE. Four patients were excluded from analysis for arrhythmia or obvious hemorrhage during VE. Baseline SVV correlated well with baseline PVI and the changes in SVV was correlated with the changes in PVI (p < 0.01) after VE. There were significant increases of CI, SVI and decreases of SVV, PVI in responder (Rs) after VE. ROC results showed that the areas for SVV, PVI were significantly higher than the areas for CI, MAP, CVP, PI (p < 0.05). The best threshold values to predict fluid responsiveness were more than 12.5% for SVV and more than 13.5% for PVI in the real surgical setting. The baseline value of SVV, and PVI correlated significantly with volume-induced changes in SVI (p < 0.01). Both SVV and PVI could be used to predict intraoperative fluid responsiveness during resection of PRPT in Hans Chinese.

Abstract
OBJECTIVE Experimental data suggest that obesity enhances the effects of ambient air pollutants on exacerbation of asthma; however, there is little supporting epidemiological evidence. The aim of present study is to evaluate whether obesity modifies the association between ambient air pollution and respiratory symptoms and asthma in children. METHODS In Northeast China, 30 056 children aged 2-14 years were selected from 25 districts of seven cities. Parents of the children completed questionnaires that characterized the children's histories of respiratory symptoms and illness, and associated risk factors. Overweight and obesity were calculated with an age and sex-specific body mass index (BMI, kg m(-2)), with BMIs of greater than the 85th and 95th percentiles defining overweight and obesity, respectively. Average annual ambient exposure to particulate matter with an aerodynamic diameter 10 μm (PM(10)), sulfur dioxide (SO(2)), nitrogen dioxides (NO(2)) and ozone (O(3)) was estimated from data collected at monitoring stations in each of the 25 study districts. RESULTS We observed consistent and significant interactions between exposure and obesity on respiratory symptoms and asthma. The associations between each pollutant's yearly concentrations and respiratory symptoms and asthma were consistently larger for overweight/obese children than for normal-weight children, with odds ratios (ORs) ranging from 1.17 per 31 μg m(-3) for PM(10) on wheeze (95% confidence interval (CI): 1.01, 1.36) to 1.50 per 10 μg m(-3) for NO(2) on phlegm (95% CI: 1.21, 1.87) and cough (95% CI: 1.24, 1.81). CONCLUSION These results showed that overweight/obesity enhanced respiratory health effects of air pollution in the study children.

Abstract
Osteosarcoma is the most common type of bone cancer, with a peak incidence in the early childhood. The relationship between microRNAs (miRNAs) and cancer development attracted more and more attention over the last few years. Members of the miRNA-29 family, including miRNA-29a, miRNA-29b, and miRNA-29c were shown to participate in the development of rhabdomyosarcoma and hepatocarcinogenesis. Here, it has been demonstrated miRNA-29a and miRNA-29b expression levels to be downregulated in most of the osteosarcoma tissues (23 from 30). Besides, miRNA-29a displayed ability to induce apoptosis in both U2OS and SAOS-2 osteoblastic cells. While miRNA-29 members induced apoptosis through p53 gene activation, the effect of miRNA-29a on osteoblastic cells was independent on p53 expression level. Moreover, Bcl-2 and Mcl-1 were earlier demonstrated to be the direct targets of miRNA-29 in many types of cancer tissues and cancers. In both U2OS and SAOS-2 osteoblastic cell types, overexpression of miRNA-29a also downregulated Bcl-2 and Mcl-1, while silencing of miRNA-29a increased their expression. In addition, enhanced expression of miRNA-29a increased the expression of two tumor suppressor genes, E2F1 and E2F3. In summary, data obtained highlight the role of miRNA-29a in the regulation of osteoblastic cell apoptosis by silencing Bcl-2 and Mcl-1 and inducing E2F1 and E2F3 expression.

Abstract
BACKGROUND The clinical importance of the HLA system is as a transplant antigen. However, correlations between the development and strength of the immune response and HLA genes or specific foreign antigens are not clear. OBJECTIVES The objectives of this study were to detect HLA-A, -B, and -DRB1 allele frequencies and HLA antibodies in sensitized patients, and to investigate the correlation between the HLA alleles and HLA sensitization. METHODS This study included 383 sensitized patients and 1000 unsensitized patients awaiting kidney transplantation from 2001-2010. HLA -A, -B, and -DRB1 typing was performed using sequence-specific primer-polymerase chain reactions (SSP-PCR). Arlequin statistical analysis software was used to calculate the HLA allele frequencies among the 2 groups. The anti-HLA-specific antibodies of sensitized patients were identified and analyzed using enzyme-linked immunosorbent assay (ELISA). RESULTS The numbers of identified HLA -A, -B, and -DRB1 alleles were 20, 43, and 14, respectively. The 5 most frequent HLA alleles in the 2 groups were not different: A-02, 11, 24, 33, 26; B-46, 60, 13, 75, 58; and DR-9, 15, 12, 4, 14. Among the sensitized group, the most frequent HLA-specific antibodies were as follows: A-2, 24, 68, 23, 32; B-27, 56, 57, 7, 60; and DR-7, 4, 9, 13, 17. CONCLUSIONS There was little correlation between HLA sensitization and HLA alleles of oneself. High frequency alleles and the specificity of high-frequency HLA antibodies were not consistent.

Abstract
OBJECTIVE To report clinical outcomes of kidney transplantation from cardiac death donors (DCD) in China, and to investigate its feasibility to expand the organ donor pool. PATIENTS AND METHODS We retrospectively studied clinical data of 46 DCD kidneys from 31 donors from February 2007 to August 2011. Recipients were followed for patient and graft survival. RESULTS We discarded the organs from 3 of 29 (10.3%) DCD donors and 7 of 42 (16.7%) kidneys that displayed renal thrombosis. Of the 39 recipients engrafted with DCD kidneys successfully, the mean follow-up was 16 months, (range = 50 days to 43 months). Delayed graft function (DGF) occurred in 15 (38.5%) recipients, who except one recovered within 3 months. Three biopsy-proven acute rejection episodes were observed in two recipients (5.1%). All patients survived through the follow-up. The graft survival rate was 97.4% at 12 months and 94.9% at 24 months. A 45-year-old male recipient who received a pair of grafts from a 6-year-old child survived with good renal function. CONCLUSION Although kidney transplantations from DCD donors showed a higher rate of DGF with a longer duration of graft recovery, we achieved favorable short-term clinical outcome in terms of graft survival and function. Donation after cardiac death can expand the organ donor pool in China.

Abstract
PURPOSE The purpose of this study was to investigate the profile of traumas, the severity, and mortality of polytrauma patients in a front-line hospital after the 2008 Sichuan earthquake. METHODS Patients who had two or more injuries to physical regions or organ systems, where at least one injury or the combination of injuries carried a certain risk of fatal outcome, with Injury Severity Score (ISS) ≥16, were considered as polytrauma patients and included in this study. Medical records consisting of demographic data, distribution and type of injuries, Abbreviated Injury Scale (AIS) score of each injury, ISS, surgical procedures, mortality rate, and features of the deaths were collected and analyzed. RESULTS A total of 70 earthquake-related polytrauma patients were treated in our hospital during the first 10 days after the earthquake. The mean ISS of these patients was 26.9, and 77.1% of these patients were critically injured (ISS ≥ 25). Among the 224 injuries, the most common injury site was the extremities (30.8%), 81.2% of which were fractures. A total of 152 surgical procedures were performed on these patients, of which orthopedic procedures accounted for 85.5%. During the first 10 days, 21 patients with significantly higher ISS than the survivors died in the hospital. CONCLUSIONS The mortality rate of the polytrauma patients in this rescue operation was high. The ISS was a feasible tool to estimate the severity of polytrauma patients. Specialists in orthopedics, critical care, and respiratory disorders were in great demand during the management of these patients in such conditions.

Abstract
Paclitaxel(PTX)-loaded microspheres composed of poly(D,L-lactide-co-glycolide) (PLGA) were prepared by an O/W emulsion solvent evaporation method. This study was designed to investigate the preparation, in vitro release, in vivo pharmacokinetics and tissue distribution of a PTX-loaded microspheres system. Microspheres are characterized according to drug loading, size and shape. With a dynamic light scattering sizer and a transmission electron microscopy, it is shown that the PTX-loaded microspheres had a mean size of approximately 10.24 µm with narrow size distribution and a spherical shape. The in vitro release profiles indicate that the release of PTX from the microspheres exhibit a sustained release behavior. A similar phenomenon is observed in a pharmacokinetic study in rats, in which AUC of the microspheres formulation were 3.7-fold higher than that of PTX injection. The biodistribution study in mice showed that the PTX-loaded microspheres not only decreased drug uptake by liver, but also increased distribution of drug in lung. These results suggest that PTX-loaded microspheres may efficiently load, protect and retain PTX in both in vitro and in vivo environments, and could be a useful drug carrier for i. v. administration of PTX.

Abstract
OBJECTIVE To evaluate the potential use of the bladder acellular matrix graft (BAMG), two different bladder defects in the rabbit model were reconstructed. MATERIALS AND METHODS Two groups of rabbits underwent partial bladder wall cystectomy (group A, 30-40%; group B, 70-60%) and reconstruction of the defects with an equally sized BAMG. After 4, 12, and 24 weeks, bladder cystographs were performed. Then the rabbits were killed after uneventful postoperative periods, and the grafts were harvested for H&E staining and immunohistochemical staining. RESULTS Two rabbits died on the postoperative days 3 and 6 in group A due to urinary peritonitis. At 24 weeks, in group A, the reconstructed bladders reached a mean volume of 94.39±0.54% of the precystectomy bladder capacity. Histologically, complete regeneration of smooth muscle and urothelium tissue was evident. Regenerated SMCs and urothelium stained positive for α-smooth muscle actin and AE1/AE3. In group B, the mean bladder volume was 64.5±3.19% of the precystectomy volume. Histologically, group B was characterized by multilayered urothelium without organized muscle tissue. CONCLUSION The BAMG was an effective scaffold for bladder wall regeneration in the rabbit model. However, the use of BAMG reconstruction in larger bladder defects did not induce the same quality and quantity of bladder regeneration as the reconstruction of smaller bladder defects.

Abstract
To assess genetic diversity in populations of the brown planthopper (Nilaparvata lugens Stål) (Homoptera: Delphacidae), we have developed and applied microsatellite, or simple sequence repeat (SSR), markers from expressed sequence tags (ESTs). We found that the brown planthopper clusters of ESTs were rich in SSRs with unique frequencies and distributions of SSR motifs. Three hundred and fifty-one EST-SSR markers were developed and yielded clear bands from samples of four brown planthopper populations. High cross-species transferability of these markers was detected in the closely related planthopper N. muiri. The newly developed EST-SSR markers provided sufficient resolution to distinguish within and among biotypes. Analyses based on SSR data revealed host resistance-based genetic differentiation among different brown planthopper populations; the genetic diversity of populations feeding on susceptible rice varieties was lower than that of populations feeding on resistant rice varieties. This is the first large-scale development of brown planthopper SSR markers, which will be useful for future molecular genetics and genomics studies of this serious agricultural pest.

Abstract
Embryo-splitting technology provides an effective procedure for increasing the number of transferable embryos per donor, producing genetically identical offspring and facilitating embryo sexing. The ability to identify the sex of embryos before transfer will offer a reliable, economical and practical procedure for buffalo breeding. In this study, we have assessed the feasibility of production of offspring with controlled sex in buffalo by first comparing the effect of blastocyst quality on the viability of demi-embryos and then identifying the sex of a demi-embryo by multiplex-nested PCR before transfer into the recipient. In vitro-matured buffalo oocytes were fertilized by IVF and cultured to the blastocyst stage for 6 to 7 days as described by Lu et al. (2007 Anim. Reprod. Sci. 100, 192–196). These blastocysts were classified in terms of their developmental pattern and morphology on a scale of 1 to 3 grades as described by McEvoy et al. (1990 Theriogenology 33, 1245–1253). Blastocysts were split into 2 equal parts by a micromanipulation system. Viability of the resulting demi-embryos was confirmed by formation of a blastocoel cavity and definite inner cell mass after culture for 24 h. One of the zone-free demi-embryos derived from a grade-1 blastocyst was cultured in TCM 199 supplemented with 10% fetal bovine serum for another 2 h, then was transplanted to a spontaneous oestrous recipient. The other demi-embryo was used for sexing by multiplex-nested PCR (Fu et al. 2007 Theriogenology 68, 1211–1218). The results showed that grade-1 blastocysts yielded more viable demi-embryos than grade-2 and grade-3 blastocysts [P < 0.01; 73/92 (79.67%) vs 32/76 (47.05%) vs 26/94 (26.53%), respectively]. Transplantation of the presumed-Y demi-embryo derived from grade-1 blastocyst into a recipient resulted in the birth of a male buffalo calf. To the best of our knowledge, this is the first buffalo calf produced following embryo splitting and PCR sexing of the embryo at the blastocyst stage. Successful birth of the desired-sex offspring in the present study indicates the feasibility of using embryo splitting in combination with multiplex-nested PCR sexing to produce offspring of controlled sex in swamp buffalo. However, the quality of embryos before splitting was an important factor governing the in vitro development of viable demi-embryos.
This study was supported by the Guangxi Science and Technology R&D Program (0626001-3-1, 0815008-2-4).

Abstract
The confined modes of surface plasmon polaritons in boxing ring-shaped nanocavities have been investigated and imaged by using cathodoluminescence spectroscopy. The mode of the out-of-plane field components of surface plasmon polaritons dominates the experimental mode patterns, indicating that the electron beam locally excites the out-of-plane field component of surface plasmon polaritons. Quality factors can be directly acquired from the spectra induced by the ultrasmooth surface of the cavity and the high reflectivity of the silver (Ag) reflectors. Because of its three-dimensional confined characteristics and the omnidirectional reflectors, the nanocavity exhibits a small modal volume, small total volume, rich resonant modes, and flexibility in mode control.
