Abstract
We evaluated the effects of an intra-aortic balloon pump on hemodynamics, brain natriuretic peptide concentration and cardiac function of patients with acute myocardial infarction, after reperfusion therapy. Sixty-three patients with acute anterior wall ST-elevation myocardial infarction who underwent primary percutaneous coronary intervention were given an intra-aortic balloon pump (32 cases) or not (control group, 31 cases). The mean pulmonary arterial pressure, pulmonary capillary wedge pressure and cardiac index were measured with a Swan-Ganz catheter. The brain natriuretic peptide concentration was detected by immunochemiluminometric assay. Left ventricular end-diastolic diameter and left ventricular ejection fraction were measured by echocardiography. No difference in baseline was observed between the two groups on day 1 in the hospital. On day 5, mean pulmonary artery pressure and pulmonary capillary wedge pressure of patients with the intra-aortic balloon pump were significantly lower, and cardiac index of was higher than that of the controls, whereas no differences in left ventricular end-diastolic diameter or left ventricular ejection fraction were observed between the two groups. On days 5 and 90, the brain natriuretic peptide concentration of the intra-aortic balloon pump patients was lower than that of the controls. On day 90, left ventricular end-diastolic diameter was smaller in the intra-aortic balloon pump patients, but no difference in left ventricular ejection fraction was observed between the two groups. The intra-aortic balloon pump improved the hemodynamic index and cardiac function and decreased brain natriuretic peptide concentration in patients with acute anterior wall ST-elevation myocardial infarction.

Abstract
It is largely recognized that fibroblast activation protein (FAP) is expressed in cancer-associated fibroblasts (CAFs) of many human carcinomas. Furthermore, FAP was recently also reported to be expressed in carcinoma cells of the breast, stomach, pancreatic ductal adenocarcinoma, colorectum, and uterine cervix. The carcinoma cell expression pattern of FAP has been described in several types of cancers, but the role of FAP in oral squamous cell carcinoma (OSCC) is unknown. The role of endogenous FAP in epithelium-derived tumors and molecular mechanisms has also not been reported. In this study, FAP was found to be expressed in carcinoma cells of OSCC and was upregulated in OSCC tissue samples compared with benign tissue samples using immunohistochemistry. In addition, its expression level was closely correlated with overall survival of patients with OSCC. Silencing FAP inhibited the growth and metastasis of OSCC cells in vitro and in vivo. Mechanistically, knockdown of FAP inactivated PTEN/PI3K/AKT and Ras-ERK and its downstream signaling regulating proliferation, migration, and invasion in OSCC cells, as the inhibitory effects of FAP on the proliferation and metastasis could be rescued by PTEN silencing. Our study suggests that FAP acts as an oncogene and may be a potential therapeutic target for patients with OSCC.

Abstract
Nilaparvata lugens is a serious phloem-feeding pest of rice throughout Asia. Rice phloem sap can meet its nutrition requirement for sugars but not for some essential amino acids such as isoleucine, leucine, methionine, phenylalanine, tryptophan, lysine, arginine and histidine. N. lugens harbours yeast-like symbionts in mycetocytes formed by abdominal fat body cells. Removal of the symbionts results in negative physiological effects, suggesting that the symbionts play a pivotal role in the nitrogen metabolism. In the present paper, 521 mRNA expressed sequence tags (ESTs) encoding 126 enzymes that were involved in amino acid biosynthesis were identified based on a transcriptome data, reverse transcription (RT)-PCR and rapid amplification of cDNA ends. Similarity analysis, codon usage bias, along with tissue-biased expression and phylogenetic analysis of a subset of ESTs, suggest that 437 ESTs out of the 521 originate from symbionts, and the remaining 84 mRNA fragments come from N. lugens. Accordingly, the biosynthesis pathways for 20 amino acids were manually constructed. It is postulated that both N. lugens and its symbiont can independently assimilate ammonia and biosynthesize seven non-essential amino acids: glutamate; glutamine; aspartate; asparagine; alanine; serine; and glycine. N. lugens and symbiont enzymes may work collaboratively to catalyse the biosynthesis of proline, methionine, valine, leucine, isoleucine, phenylalanine and tyrosine. We infer from this that symbionts function in the biosynthesis of lysine, arginine, tryptophan, threonine, histidine and cysteine. Our data support the previously proposed hypothesis, i.e. the yeast-like symbionts compensate for, at least partially, the amino acid needs of N. lugens.

Abstract
UNLABELLED The expression of α2-Heremans-Schmid-glycoprotein (AHSG) was estrogen responsive in oophorectomized (OVX) osteopenic rats and HepG2 cells. Estrogen receptor α (ERα) interacted with the c-Jun/c-Fos heterodimer and indirectly associated with the -1488/-1482 activator protein-1 (AP-1) motif of the AHSG promoter. Estrogen increased c-Jun/c-Fos expression via the mitogen-activated protein kinase (MAPK) pathway. INTRODUCTION AHSG is a hepatic secretory protein implicated in the regulation of bone homeostasis. Serum AHSG in women has been reported to decrease after menopause and increase with estrogen therapy. The detailed regulatory mechanism of estrogen on AHSG is unclear. METHODS A postmenopausal osteoporosis model was generated in OVX rats. Skeletal parameters were determined by automatic biochemical analysis and dual X-ray absorptiometry. The expression of AHSG was evaluated by ELISA, real-time PCR, and Western blot. The 1.5-kb 5'-promoter region of AHSG was analyzed by serial truncation and luciferase assays. The putative -1488/-1482 AP-1 responsive element was identified by electrophoresis mobility shift assay (EMSA). Chromatin immunoprecipitation (ChIP), re-ChIP, and co-immunoprecipitation (Co-IP) were used to characterize the interaction of ERα and AP-1 at the -1488/-1482 AP-1 binding site. The MAPK pathway was evaluated using a specific inhibitor and active transfection. RESULTS The expression of AHSG was estrogen responsive in both OVX rats and estradiol (E2)/ERα-treated HepG2 cells. E2/ERα most prominently increased luciferase activity of a construct with a putative -1488/-1482 AP-1 binding element. ERα interacted with the c-Jun/c-Fos heterodimer and indirectly associated with the -1488/-1482 AP-1 motif of the AHSG promoter. c-Jun/c-Fos expression was increased via the MAPK pathway by E2/ERα. CONCLUSION Estrogen activated the transcription of AHSG through an indirect binding of ERα to the -1488/-1482 AP-1 binding element, with the c-Jun/c-Fos heterodimers.

Abstract
OBJECTIVE In recent years, the field of cancer immunotherapy has become a research hotspot and is currently faced with numerous challenges. The objective of this study was to assess the success of cbl-b gene silencing in splenic T lymphocytes as an immune strategy to target the murine prostate cancer RM-1 cells in vitro and solid tumors in vivo. MATERIALS AND METHODS For this purpose, cbl-b gene-specific siRNA was designed, synthesized, and was transfected into mouse splenic T lymphocytes, followed by assessment of T cell activation, TH1 cytokine production, and in vitro cytotoxicity against RM-1 cell targets. For in vivo cytotoxicity studies, first the RM-1 tumor model was established in immune competent mice that were later tumor-injected with splenic T lymphocytes transfected with specific shRNA for cbl-b gene silencing. RESULTS The data show that the cbl-b gene silencing in T lymphocytes resulted in an enhanced surface expression of CD69 activation marker, elevated production of interleukin (IL)-2 and interferon (IFN)-γ, and their increased cytotoxicity as effectors against RM-1 prostate cancer cells. The tumor injection with cbl-b shRNA-transfected T lymphocytes also resulted in significant reduction of the tumor size as compared with controls. CONCLUSIONS cbl-b gene silencing strategy enhanced the immune function of T lymphocytes, increased their cytotoxic potential against RM-1 prostate cancer cells, as well as caused significant suppression of the tumor growth in immune competent mice.

Abstract
BACKGROUND Osteosarcoma is a kind of highly malignant primary bone tumor which most common in the teenage, and holds strong aggressive, earlier organs metastases mainly to lung, prone to postoperative recur. Therefore for osteosarcoma, invasion and transfer mechanism and related factors' interaction remains to be a key research subject. AIM We aim to find biological molecules marker can be used for osteosarcoma diagnosis through contrast of osteosarcoma sample and normal tissue samples. MATERIALS AND METHODS This analysis using human osteosarcoma expression profile data and three lesions normal tissue samples (liver, kidneys, lymph) expression data and compare them, and find significant specifically expressed genes, according to their function. RESULTS Research shows that the cancer cell proliferation, invasion, transfer and recurrent process involve many factors interaction, of which angiogenesis is the necessary condition of tumor growth, transfer and the recurrence. CONCLUSIONS Now the most important positive regulatory factor of angiogenesis is VEGF (vascular endothelial growth factor) and bFGF (basic fibroblast growth factor). Both of them are with a wide variety and close relationship of tumor angiogenesis and progress.

Abstract
Autosomal recessive retinitis pigmentosa (arRP) is a clinically and genetically heterogeneous retinal disease that causes blindness. Our purpose was to identify the causal gene, describe the phenotype and delineate the mutation spectrum in a consanguineous Quebec arRP family. We performed Arrayed Primer Extension (APEX) technology to exclude ∼500 arRP mutations in ∼20 genes. Homozygosity mapping [single nucleotide polymorphism (SNP) genotyping] identified 10 novel significant homozygous regions. We performed next generation sequencing and whole exome capture. Sanger sequencing provided cosegregation. We screened another 150 retinitis pigmentosa (RP) and 200 patients with Senior-Løken Syndrome (SLS). We identified a novel missense mutation in WDR19, c.2129T>C which lead to a p.Leu710Ser. We found the same mutation in a second Quebec arRP family. Interestingly, two of seven affected members of the original family developed 'sub-clinical' renal cysts. We hypothesized that more severe WDR19 mutations may lead to severe ciliopathies and found seven WDR19 mutations in five SLS families. We identified a new gene for both arRP and SLS. WDR19 is a ciliary protein associated with the intraflagellar transport machinery. We are currently investigating the full extent of the mutation spectrum. Our findings are crucial in expanding the understanding of childhood blindness and identifying new genes.

Abstract
BACKGROUND We analyzed outcomes of kidney transplantation (KTx) from donation after brain death (DBD) or cardiac death (DCD) in China under the current level of the health care system. METHODS Among 94 KTx performed from February 2007 to March 2012 in two organ transplant centers in the south of China, 50 KTx were used DBD and 44 DCD donors. We retrospectively analyzed the clinical outcomes. RESULTS At a mean follow-up of 25.5 months, the 1-year and 2-year graft survival rates were 96.8% and 95.2% respectively. Delayed graft function (DGF) occurred in 27.7% recipients, three of whom lost graft function. Among six observed acute rejection episodes, five were reversed. When compared to the DCD group in DBD patients were apt to recover from DGF. Serum creatinine decreased more promptly in the DBD than in DCD group. Serum creatinine in the DCD group increased after months 12, when it was significantly higher than that in the DBD group (P < .05). CONCLUSIONS Kidney transplantation from DBD donors showed good outcomes with few complications. Although KTx from DCD donors showed a higher DGF rate and longer duration of graft recovery, we achieved favorable short-term clinical outcome using this source.

Abstract
Disc degeneration is strongly associated with back or neck pain, sciatica, and disc herniation or prolapse. It places an enormous economic burden on society and can greatly affect quality of life. Alternative treatment approaches, such as genetic therapies, are urgently needed to slow or reverse the disc degeneration process. We downloaded gene expression data from Gene Expression Omnibus during various stages of disc degeneration and identified differentially expressed genes (DEGs) as well as dysfunctional pathways through comparisons with controls. We identified 2 significant DEGs between grade II and III discs and 8 significant DEGs between grade II and IV discs. By constructing an interactive network of the DEGs, we found that mitogen-activated protein family genes and Ras homologous (Rho) family genes - in particular, MAP2K6 and RHOBTB2 - may play important roles in the progression of degeneration of grade III and IV discs, respectively. MAP2K6 and RHOBTB2 may be specific therapeutic molecular targets in the treatment of disc degeneration. However, further experiments are needed to confirm this result.

Abstract
Plasmonic circuitry is considered as a promising solution-effective technology for miniaturizing and integrating the next generation of optical nano-devices. A key element is the shared metal network between electrical and optical information enabling an efficient hetero-integration of an electronic control layer and a plasmonic data link. Here, we investigate to what extent surface plasmons and current-carrying electrons interfere in such a shared circuitry. By synchronously recording surface plasmon propagation and electrical output characteristics of individual chemically-synthesized silver nanowires we determine the limiting factors hindering the co-propagation of an electrical current and a surface plasmon in these nanoscale circuits.

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.

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.

Abstract
To assess whether Treg/Th17 balance was broken in patients with idiopathic dilated cardiomyopathy (DCM). We studied 25 patients who were diagnosed as idiopathic DCM (18 men and seven women, mean age 35.6 +/- 5.2) and 25 normal persons (18 men and seven women, mean age 33.8 +/- 4.9). Then, we detected Treg/Th17 functions on different levels including cell frequencies, related cytokine secretion and key transcription factors in patients with idiopathic DCM and controls. The results demonstrated that patients with idiopathic DCM revealed significant increase in peripheral Th17 number, Th17-related cytokines (IL-17, IL-6, IL-23) and transcription factor (RORgammat) levels and obvious decrease in Treg number, Treg-related cytokines (TGF-beta1 and IL-10) and transcription factor (Foxp3) levels when compared to normal persons. Results indicated that Treg/Th17 functional imbalance existed in patients with idiopathic DCM, suggesting a potential role for Treg/Th17 imbalance in the development of idiopathic DCM.

Abstract
OBJECTIVE To analyze the clinical effects of laparoscopic sacral colpopexy using prolene mesh for patients with pelvic organ prolapse. METHODS Laparoscopic placement of prolene mesh in the rectovaginal septum and veslcovaginal septum of 42 women with uterine prolapse with bladder and rectum prolapse. One mesh was fixed to the round ligaments and another to the periosteum of the sacral vertebrae. Operation time, blood loss, complication rate and follow-up surgery results were recorded monthly and analyzed according to the POP-Q system. The uterus was preserved in all cases. RESULTS The mean operating time was 92 +/- 12 min and the mean blood loss during surgery was 98 +/- 11 ml. Postoperatively, both prolapse and symptoms were highly significantly improved (p < 0.001) according to the pelvic organ prolapse quantification (POP-Q) system. CONCLUSIONS Laparoscopic sacral colpopexy for uterine prolapse using prolene mesh is a minimally invasive and effective new technique that offers a chance for patients who desire to preserve their uterus.

Abstract
We report a photonic approach for selective inactivation of viruses with a near-infrared subpicosecond laser. We demonstrate that this method can selectively inactivate viral particles ranging from nonpathogenic viruses such as the M13 bacteriophage and the tobacco mosaic virus to pathogenic viruses such as the human papillomavirus and the human immunodeficiency virus (HIV). At the same time, sensitive materials such as human Jurkat T cells, human red blood cells, and mouse dendritic cells remain unharmed. The laser technology targets the global mechanical properties of the viral protein shell, making it relatively insensitive to the local genetic mutation in the target viruses. As a result, the approach can inactivate both the wild and mutated strains of viruses. This intriguing advantage is particularly important in the treatment of diseases involving rapidly mutating viral species such as HIV. Our photonic approach could be used for the disinfection of viral pathogens in blood products and for the treatment of blood-borne viral diseases in the clinic.
