Abstract
BACKGROUND Bardet-Biedl Syndrome (BBS) is a genetically heterogeneous autosomal recessive disorder with a wide spectrum of clinical features. To date, mutations in 21 different genes (BBS1-21) have been identified as causing isolated or complex BBS phenotypes. In this report, we present three Chinese Miao ethnic patients who were diagnosed with BBS on the basis of characteristic clinical features and investigated the exsome of these patients. METHODS To evaluate disease genes, the Agilent SureSelect system and Illumina HiSeq 2000 platform for whole exome enrichment and sequencing (WES) were used on the proband and her mother. Variants that fit a recessive model of inheritance only were compared and filtered using public databases. Variants detected by exome sequencing were validated by Sanger sequencing. A total of 981 phenotypically normal subjects were enrolled as control data set. RESULTS A frameshift homozygous germline mutation in BBS7 was detected by WES and identified by Sanger sequencing in affected individuals. This mutation was predicted to result in premature termination of exon5 (c.389_390delAC, p.Asn130ThrfsX3; RefSeq NM_176824.2) and lead to a 133 amino acid truncated protein. The inheritance patterns in the families are consistent with autosomal recessive inheritance, and no such homozygous mutation was found in the other 981 controls. CONCLUSION This mutation has not yet been described in any reported literature, and this is the first report on BBS7 mutation in Chinese Miao families with BBS phenotypes.

Abstract
Objective: To compare and analyze the epidemiological characteristics of hospitalized elderly, young and middle-aged patients with severe burn in recent years, so as to provide reference for the prevention and treatment of elderly patients with severe burn. Methods: Relying on the entry system of epidemiological case data and biological sample of severe burn from multicenter in clinic, medical records of patients with severe burn, aged above 18, hospitalized in 8 burn wards from January 2012 to December 2015 were collected. Six hundred and fifteen patients who were more than 18 years old and less than or equal to 65 years old were included in young and middle-aged group (YM). Eighty-two patients aged more than 65 years old were included in elderly group (E). Data of age, gender, residence, education level, cause of injury, location of injury, season of injury, total burn area, occurrence and area of full-thickness burn injury, wound site, inhalation injury incidence and severity, post burn admission time, proportion of delayed resuscitation, proportion of escharectomy or tangential excision and skin grafting, preinjury systemic disease, system complication during hospitalization, length of hospital stay, outcome of treatment, and reason of abandoning treatment of patients were analyzed. Data were processed with chi-square test and Mann-Whitney U test. The odds ratios of preinjury systemic disease, system complication during hospitalization, and adverse outcome of patients in group YM were compared with those in group E. Results: (1) The majority of patients in the two groups were male, but the proportion of male patients in group YM was higher. There was statistically significant difference in gender distribution of patients between the two groups (χ(2)=18.727, P<0.001). The majority of patients in the two groups were from rural areas, but the proportion of rural patients in group E was higher. There was statistically significant difference in residence distribution of patients between the two groups (χ(2)=9.306, P=0.002). Patients in group YM mainly had secondary education, while patients in group E mainly had primary education. There was statistically significant difference in distribution of education level of patients between the two groups (χ(2)=146.797, P<0.001). (2) The most common causes of injury of patients in the two groups were both flame, but the proportion of patients with flame burn injury in group E was higher. There was statistically significant difference in distribution of cause of injury of patients between the two groups (χ(2)=25.063, P<0.001). The main locations of injury of patients in groups YM and E were respectively public place and private residence. There was statistically significant difference in location distribution of injury of patients between the two groups (χ(2)=46.313, P<0.001). The main seasons of injury of patients in groups YM and E were respectively summer and winter. There was statistically significant difference in season distribution of patients between the two groups (χ(2)=23.143, P<0.001). There was statistically significant difference in distribution of total burn area of patients between the two groups (χ(2)=25.799, P=0.002). The occurrences of full-thickness burn injury of patients in the two groups were similar (χ(2)=2.685, P=0.101), while there was statistically significant difference in area of full-thickness burn injury of patients between the two groups (χ(2)=26.702, P=0.002). There was no statistically significant difference in distribution of wound site of patients between the two groups (χ(2)=3.954, P=0.785). There were no statistically significant differences in incidence and severity distribution of inhalation injury of patients between the two groups (with χ(2) values respectively 0.425 and 0.672, P values above 0.05). (3) There was statistically significant difference in distribution of admission time of patients between the two groups (χ(2)=6.632, P=0.036), but there was no statistically significant difference in proportion of delayed resuscitation of patients between the two groups (χ(2)=1.261, P=0.261). The proportion of escharectomy or tangential excision and skin grafting of patients in group YM was 72.0% (443/615), which was significantly higher than 35.4% (29/82) of group E (χ(2)=44.498, P<0.001). The incidence of preinjury systemic disease of patients in group YM was 13.2% (81/615), which was significantly lower than 61.0% (50/82) of group E (χ(2)=108.337, P<0.001). The risk of preinjury systemic disease of patients in group E was 10.30 times of that of patients in group YM [with 95% confidence interval (CI) of 6.24-17.01, P<0.001]. During hospitalization, 59.8% (49/82) of patients in group E suffered from system complications, which was significantly higher than 36.6% (225/615) of group YM (χ(2)=16.282, P<0.001). The risk of system complication of patients in group E was 2.57 times of patients in group YM (with 95% CI of 1.61-4.12, P<0.001). The length of hospital stay of patients in group E was significantly shorter than that of group YM (U=36 735, P<0.001). There was statistically significant difference in treatment outcome of patients between the two groups (χ(2)=106.251, P<0.001). The risk of adverse outcome of patients in group E was 7.52 times of group YM (with 95% CI of 4.40-12.88, χ(2)=67.709, P<0.001). The proportion of abandoning treatment of patients in group E was significantly higher than that of group YM (χ(2)=150.670, P<0.001). The risk of abandoning treatment of patients in group E was 15.86 times of that of group YM (with 95% CI of 9.36-26.88, P<0.001). There was no statistically significant difference in distribution of reason of abandoning treatment of patients between the two groups (χ(2)=4.178, P=0.243). Conclusions: There were significant differences in the epidemiological characteristics of patients in groups E and YM. In elderly burn patients, the proportion of rural population was higher and the education level was lower. Flame burn was common and burns mostly occurred in private residences and in winter. The total burn area was slightly lower but the area of full-thickness burn injury was larger. The length of hospital stay was shorter and the proportion of surgical treatment was lower. The incidences of preinjury systemic disease and system complication during hospitalization were higher, and therefore the risks of adverse outcome and abandoning treatment were higher.

Abstract
OBJECTIVE To analyze Mycoplasma genitalium (MG) infection among the patients attending the clinic of sexually transmitted diseases (STD) in Nanjing. METHODS Urethral and cervical swabs were collected from 2 753 patients (2 161 males and 592 females) who first sought medical care at our STD Clinic from November 2015 to December 2017. The patients ranged in age from 18 to 67 years ([37.55 ± 10.37] yr), divided into six age groups: ≤20, 21-30, 31-40, 41-50, 51-60, and >60 yr. The samples were examined for MG infection by simultaneous amplification and testing, Chlamydia trachomatis (CT) by quantitative real-time PCR, Neisseria gonorrhoeae (NG), Ureaplasma urealyticum (UU) and Mycoplasma hominis (MH) with the Thayer-Martin medium, and the count of polymorphonuclear leukocytes (PMNL) by microscopy with Methylene blue stain. RESULTS Among the 2 753 samples, 219 (7.95%), including 176 males (8.14%) and 43 females (7.26%), were found positive for MG, with no statistically significant differences between the male and female groups (χ2 = 0.492, P = 0.483). The MG infection rates in the male and female groups were 6.67% vs 12.12% in the ≤20-year-olds, 8.44% vs 8.64% in the 21-30-year-olds, 7.63% vs 6.19% in the 31-40-year-olds, 10% vs 4.72% in the 41-50-year-olds, 5.64% vs 0 in the 51-60-year-olds, and 8.33% vs 0 in the >60-year-olds, with no statistically significant differences among the age groups (χ2 = 4.76, P = 0.446), or in the males (χ2 = 7.240, P = 0.200) or females (χ2 = 6.718, P = 0.076). The incidence rate of MG simple infection was markedly higher in the males than in the females (62.30% [76/122] vs 36.84% [14/38], χ2 = 7.041, P < 0.01). MG infection was found in combination with one or more pathogens like NG, CT, UU and MH, with MG+UU as the most common co-infection (21.31% [26/122] in males and 31.85% [12/38] in females). Of the 76 male patients with MG simple infection, 30 (39.47%) had ≥5 PMNLs per high-power field, and 66 (86.84%) showed symptoms of urethritis. CONCLUSIONS MG infection was found in both the symptomatic and asymptomatic patients attending the STD clinic in Nanjing, with no significant difference in the incidence rate between males and females. A higher rate of MG simple infection was observed in the males than in the females, most of the male patients with symptoms of urethritis and urethral PMNLs.

Abstract
BACKGROUND Pollen tube formation and growth are crucial steps that lead to seed production. Despite the importance of pollen tube growth, the molecular mechanisms implicated in its spatial and temporal control are not fully known. In this study, we found an uclacyanin gene, OsUCL8, that regulates pollen intine deposition and pollen tube growth. FINDINGS The overexpression of OsUCL8 led to a striking irregularity in pollen tube growth and pollination and thus affected the seed setting rate in rice; many pollen tubes appeared to lose the ability to grow directly into the style. Conversely, plants with OsUCL8 knocked out and plants overexpressing miR408, a negative regulator of OsUCL8, had vigorous pollens with a higher germination rate. We further demonstrated that OsUCL8 mainly affects pollen intine formation. The addition of Vitamin B1 (VB1) significantly contributed to the germination of OXUCL8 pollen grains, suggesting that OsUCL8 could be associated with VB1 production. Using a yeast two-hybrid system, we revealed that OsUCL8 interacts with the protein OsPKIWI, a homolog of the Arabidopsis FNRL protein. We thus hypothesized that OsUCL8 might regulate the production of VB components by interacting with OsPKIWI. This study revealed a novel molecular mechanism of pollen tube growth regulation. CONCLUSIONS The rice plantacyanin family member OsUCL8 plays an important role in pollen tube formation and growth and, in turn, regulates fertility and the seed setting rate.

Abstract
Halyomorpha halys is a major herbivore insect in the fruit orchards of China that has become a devastating invasive pest in North America and Europe since its accidental introductions in the 1990s and 2000s, respectively. Like other hemipteran insects, H. halys releases defensive chemicals against natural enemies, including (E)-2-decenal, which is an aldehyde associated with alarm pheromones. In this study, a series of electrophysiological and behavioral tests were conducted to characterize the alarm functions of (E)-2-decenal among H. halys adults and nymphs. An antennal transcriptome was obtained from a Chinese H. halys population, and 44 odorant-binding protein (OBP) genes were annotated. Among them, five putative alarm pheromone-binding proteins were screened and were extremely consistent with their homologs from US populations. These five OBPs were later expressed in a heterologous expression system, harvested, and then challenged with (E)-2-decenal in a binding assay. All five OBPs showed high binding activities to (E)-2-decenal, which demonstrated its behavioral significance as a defensive component in H. halys, as well as being the first report of its olfactory reception. These findings will help develop behavioral-mediating tools as part of integrated pest management approaches to control this invasive pest.

Abstract
New silver-containing dressings developed in recent years have brought new and powerful means for the prevention and treatment of wound infection, which promote development and progress of wound therapy. There are many kinds of silver-containing dressings, however, misunderstanding and even misapplication exist in how to choose and use these dressings. Based on literature evidence, we propose this national expert consensus on clinical application of silver-containing dressings, particularly in terms of kinds and mechanisms, indications, contraindications, rational selections in different wounds, and cautions in the clinical application of silver-containing dressings. This consensus would be helpful for medical and nursing personnels to use silver-containing dressings in wound repair field in clinic correctly and professionally.

Abstract
Objective: To investigate the relationship between the level of amniotic fluid inflammatory factor and the pregnancy outcome in patients with cervical incompetence. Methods: A retrospective case-control study was conducted. Totally 110 cases of pregnant women were diagnosed as cervical incompetence for cervical dilation at the medical examination in Sun Yat-sen Memorial Hospital of Sun Yatsen University, from January 1st, 2015 to December 31th, 2016. A total of 32 patients (29.1%, 32/110) were performed cervical cerclage. According to their neonatal outcomes, they were divided into live infant group (23 cases, 72%) and dead infant group (9 cases, 28%) . The demographic and clinical data of two groups were analyzed and compared. Results: The mean peripheral blood leucocyte counts, the median amniotic tumor necrosis factor-α (TNF-α) and the median interleukin-8 (IL-8) level of two groups were (10.5±2.8) ×10(9)/L vs (13.6±3.1) ×10(9)/L, 23.80 ng/L (14.9-85.5 ng/L) vs 379.00 ng/L (70.2-418.5 ng/L) , and 3 354 ng/L (1 020-7 500 ng/L) vs 7 500 ng/L (4 210-7 500 ng/L) respectively. The differences were statistically significant (all P<0.05) . The amniotic fluid IL-1β, IL-2 receptor, IL-6, IL-10, C-reactive protein and procalcitonin were not significantly different (all P>0.05) between two groups. Conclusions: The peripheral blood leucocyte counts, amniotic fluid TNF-α and IL-8 level are the factors affecting the pregnancy outcome in women with cervical incompetence before cervical cerclage. When IL-8 is higher than 3 580 ng/L and TNF-α is higher than 105 ng/L, the death of perinatal infants could be predicted.

Abstract
Tumor-derived exosomes (TEX) play an important role in the escape of tumor cells from immune surveillance. However, the details of the mechanism are not fully understood. In this study, the apoptosis of CD4+ T cells increased during treatment with B16-derived exosomes in vitro and in vivo, resulting in accelerated growth of melanoma cells in mice. While the release of exosomes was blocked by disrupting the expression of Rab27a, tumor growth was clearly inhibited, and the percentage of T cells in the tumor environment increased. At the same time, Western blot showed that TEX could increase the activation of caspase-3, caspase-7 and caspase-9 but not caspase-8, down-regulating the anti-apoptotic proteins, including BCL-2, MCL-1 and BCL-xL in CD4+ T cells, and indicating that the TEX activates the mitochondrial apoptotic pathway of CD4+ T cells. These reductions were probably associated with the release of microRNAs, such as miR-690, from TEX to T cells. Our present study reveals for the first time that melanoma-released exosomes may directly activate the mitochondrial apoptotic pathway of CD4+ T cells through their microRNA cargo.

Abstract
Objective: To analyze the effect of NCCN (2015) risk stratification on prognosis of patients with acute myeloid leukemia (AML) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Methods: Retrospective analysis of 258 patients with AML in CR (186 cases in CR(1), 72 cases in CR(2)) who underwent allogeneic HSCT in our hospital between April 2012 and March 2015 according to NCCN (2015) risk stratification. Of them, 63 cases were classified as low risk, 112 cases intermediate risk and 83 cases high risk. Results: ①With the median follow up of 18 (5-41) months, two-year disease free surviva (DFS) in 258 patients was 78.0% (95% CI 60.4%-96.6%) . Two-year DFS in AML after transplantation was 78.6% (95% CI 61.0%-96.2%) in low risk, 76.0% (95% CI 84.0%-93.6%) in intermediate risk and 80.3% (95% CI 62.7%-97.9%) (P=0.886) in high risk groups respectively. ②Univariate analysis showed that DFS has no significant difference in patient age, the median disease course before HSCT, the WBC number at the beginning of the disease, blood routine and chromosomes examination before transplantation, extramedullary disease before transplantation, disease status before transplantation, conditioning regimen, donor type, donor and recipient sex, recipient blood type, transfused MNC number, transfused CD34(+) cell number and transfused CD3(+) cell number. DFS was significant lower in primary AML than that in secondary AML (P=0.006) and also lower in MRD positive than that in MRD negative (P=0.003) . The accumulative relapse was significant higher in CR(2) compared to that in CR(1) (P=0.046) . Accumulative non-relapse mortality (NRM) was significanlyt higher in secondary AML compared to that in primary AML (P=0.004) and also higher in MRD positive compared to that in MRD negative (P=0.010) . ③Multivariate analysis showed that MRD positive was the only significant factor in DFS and NRM. Conclusion: Allo-HSCT treatment of AML CR patients could achieve a high efficacy, which is similar between CR(1) and CR(2) patients. There is no significant correlation between NCCN (2015) risk stratification and the prognosis of AML patients with allo-HSCT treatment. Pre-conditioning MRD status monitored by multiparameter flow cytometry was the only impact factor on DFS and NRM in allo-HSCT for CR-AML patients.

Abstract
Bacterial cellulose (BC) is a promising material for wound dressing due to its predominant water binding capacity, mechanical property, biodegradability, and histocompatibility. Whereas BC itself exhibits no antimicrobial activity. To gain antimicrobial activity, several kinds of antibacterial agents have been introduced into BC. However, all of the antibacterial composite dressings are still in the stage of experimental research. In this paper, the types, antibacterial mechanism, and shortcomings of antibacterial composite dressings based on BC are summarized, in order to make prospects of the research trends of antibacterial composite dressings based on BC in future.

Abstract
The optimal treatment for patients with chronic symptomatic middle cerebral artery (MCA) total occlusion is not well established. In addition to medical therapy, vessel recanalisation with stenting has shown much promise, especially for patients with recurrent ischemic symptoms. Nevertheless, the incidence of symptomatic in-stent restenosis (ISR) is high, and is associated with an unfavorable prognosis. Drug coated balloons (DCBs) have been proven to be effective in treating and preventing ISR. However, the feasibility of DCBs for de novo intracranial atherothrombotic stenosis has not been previously described, especially for total occlusion lesions. Here we reported a patient with chronic left MCA total occlusion successfully treated with DCBs, with a good outcome at the 1 year follow-up. More studies are warranted to further compare the efficacy of DCBs and stentings for intracranial revascularisation.

Abstract
Objective:There is a significant difference in the hearing rehabilitation between the congenitally deaf children after cochlear implant(CI). The intrinsic mechanism that affects the hearing rehabilitation in patients was discussed from the perspective of evoked EEG source activity.Method:Firstly, we collected the ERP data from 23 patients and 10 control group children during 0, 3, 6, 9 and 12 months after CI. According to the hearing rehabilitation during 12 months after CI, the patients were divided into two groups: rehabilitation of "the good" and "the poor". Then we used sLORETA to show the changes in the groups of patients' cerebral cortex and compared with the control group.Result:Cross-modal reorganization of cerebral cortex exists in the congenitally deaf children. The cross-modal reorganization gradually degraded and the activity of the relevant cortex followed by normally after CI. There was a statistically significant difference(P < 0.05) in the temporal lobe and the associated cortex around parietal lobe between "the good" and "the poor" groups after 12 months.Conclusion:The normalization of the cross-modal reorganization in patients reflects the hearing rehabilitation after CI, especially the normalization of the activity of the temporal lobe and the associated cortex around parietal lobe, which influences the rehabilitation effect of the auditory function to some extent. This research demonstrated the detection of the mechanism has important significance for the hearing recovery training and evaluation of the hearing rehabilitation after CI.

Abstract
Increasing grain yield is the most important object of crop breeding. Here, we report that the elevated expression of a conserved microRNA, OsmiR408, could positively regulate grain yield in rice (Oryza sativa) by increasing panicle branches and grain number. We further showed that OsmiR408 regulates grain yield by down-regulating its downstream target, OsUCL8, which is an uclacyanin (UCL) gene of the phytocyanin family. The knock down or knock out of OsUCL8 also increases grain yield, while the overexpression of OsUCL8 results in an opposite phenotype. Spatial and temporal expression analyses showed that OsUCL8 was highly expressed in pistils, young panicles, developing seeds, and inflorescence meristem and was nearly complementary to that of OsmiR408. Interestingly, the OsUCL8 protein was localized to the cytoplasm, distinct from a majority of phytocyanins, which localize to the plasma membrane. Further studies revealed that the cleavage of OsUCL8 by miR408 affects copper homeostasis in the plant cell, which, in turn, affects the abundance of plastocyanin proteins and photosynthesis in rice. To our knowledge, this is the first report of the effects of miR408-OsUCL8 in regulating rice photosynthesis and grain yield. Our study further broadens the perspective of microRNAs and UCLs and provides important information for breeding high-yielding crops through genetic engineering.

Abstract
AIMS This study was to investigate whether cell proliferation and adult neurogenesis are affected at early neurodegenerative stage when neuron loss has not begun to display. METHODS AND RESULTS Forebrain-specific nicastrin (NCT) conditional knockout (cKO) mice were generated by crossing NCTf/f with CaMKIIα-Cre Tg mice. BrdU was used as a lineage tracer to label proliferating neural progenitor cells (NPCs). Immunohistochemistry (IHC) on BrdU indicated that the total number of BrdU positive (+) cells was increased in NCT cKO mice. IHC on doublecortin (DCX) showed that the total number of DCX+ cells was also increased in NCT cKO mice. NCT cKO mice displayed significant astrogliosis as well. However, NCT cKO mice at 3 months did not show significant neuronal death or synaptic loss. CONCLUSIONS NCT-dependent γ-secretase activity plays an important role in cell proliferation and immature neuron generation. Enhanced neurogenesis and astrogliosis may be early cellular events prior to the occurrence of neuronal death in neurodegenerative disease.

Abstract
Transient global ischemia (TGI) is a major public health problem, and it heightens the need of effective treatments. The present study was undertaken to investigate whether recombinant polypeptide Tat-HA-NR2B9c improves spatial learning and memory deficits in rats after TGI. Rats were subjected to 20-min ischemia induced by four-vessel occlusion (4-VO) method and daily injected with Tat-HA-NR2B9c (1.12 mg/kg) for 1 week. Tat-HA-NR2B9c increased CREB activity, upregulated B-cell lymphoma-2 (Bcl-2) expression after treated for 24 h. There was a significant increase in dendrite spine density in hippocampal CA1 region and BrdU-positive cells and BrdU/NeuN-positive cells in the dentate gyrus after Tat-HA-NR2B9c treatment, compared with ischemia group at postischemic day 28. Inhibition of the CREB activation by recombinant lentivirus, LV-CREB133-GFP, abolished the upregulation effects of Tat-HA-NR2B9c on Bcl-2 expression. Moreover, Tat-HA-NR2B9c improved the impaired spatial learning and memory ability in Morris water maze. These results suggest that Tat-HA-NR2B9c substantially ameliorated the TGI-induced loss of dendrite spine in hippocampal CA1, increased neurogenesis in dentate gyrus, and significantly improved cognitive abilities by the CREB pathway in rats after transient global cerebral ischemia. It may be served as a treatment for TGI.

Abstract
BACKGROUND The present post hoc analysis investigated whether changes in endogenous glucagon-like peptide-1 (∆GLP-1) levels are associated with weight loss in newly diagnosed diabetes patients. METHODS In all, 784 subjects from the Metformin and AcaRbose in Chinese as initial Hypoglycemic treatment (MARCH) study were stratified according to ∆GLP-1. Changes in clinical and physiological parameters were evaluated across ∆GLP-1 subgroups (low, medium, and high) to assess correlations between ∆GLP-1 and weight loss in acarbose- versus metformin-treated groups. RESULTS After 24 weeks treatment, greater ∆GLP-1 was associated with significantly greater weight loss (-2 vs -1 kg in the medium/high vs low ∆GLP-1 groups, respectively) and reduction in body mass index (BMI; -0.88, -0.83, and -0.69 kg/m2 in the high, medium, and low ∆GLP-1 groups, respectively). In the acarbose-treated group, there was a significant association between ∆GLP-1 and BMI reductions, and greater ∆GLP-1 across the high, medium, and low ∆GLP-1 groups was correlated with greater weight loss (-2.8, -2.1, and -1.9 kg, respectively) and reductions in fasting plasma glucose (-1.57, -1.28, and -1.02 mmol/L, respectively) at Week 24. No significant differences were found across ∆GLP-1 subgroups in metformin-treated patients (P > 0.05). Multivariate linear regression analysis revealed that gender, baseline BMI, and ∆GLP-1 at Week 24 were associated with weight loss. Baseline BMI and ∆GLP-1 in the acarbose-treated group and baseline BMI in the metformin-treated group predicted weight loss at Week 24. CONCLUSION Changes in GLP-1 levels are associated with weight loss in newly diagnosed Chinese diabetes patients receiving acarbose.

Abstract
Objective: To explore the application of endometriosis fertility index (EFI) in guidance after laparoscopic surgery of endometriosis patients combined with infertility and to explore methods to improve pregnancy rate in different EFI groups. Methods: A prospective research was done in endometriosis patients combined with infertility in Beijing Obstetrics and Gynecology Hospital from January 2010 to June 2011, after laparoscopic surgery, these 146 patients were divided into 3 groups by EFI score. Using different pregnancy guidance, these patients had 5 years follow-up. Results: (1) The 5 years overall pregnancy rate was 89.0% (130/146). The pregnancy rate was 95.7% (45/47) in EFI≥9 group, 92.8% (77/83) in EFI 5-8 group and 8/16 in EFI≤4 group, three groups were all reach satisfactory pregnancy rate; the rate of the first two groups had no statistically significance (P=0.498), but had significant difference with the last group (P<0.01). (2) In EFI≥5 patients, pregnancy rate was the highest in 6 months after operation; in EFI≥9 group, the pregnancy rate was 66.7% (30/45), and EFI 5-8 group was 50.6% (39/77). (3) EFI≥9 group had the highest natural pregnancy rate [83.6% (46/55)], natural pregnancy rate was significant statistical different in different EFI groups (P=0.001). Conclusions: EFI score is a useful evaluation in predicting and guiding pregnancy in endometriosis patients combined with infertility after laparoscopic surgery. EFI score guidance, strict post-operation management and positive pregnancy scheme could significantly improve the pregnancy rate of endometriosis patients with infertility.

Abstract
Serofast, a persistent nontreponemal serological response observed in early syphilis patients after conventional treatment, remains a concern of clinicians and syphilis patients. No consensus has been established, however, that defines an effective treatment strategy and clarifies the pathogenesis. In this study, 517 patients with early syphilis were enrolled and treated. Twelve months after treatment, 79.3% (410/517) of patients achieved serological cure, 20.1% (104/517) were serofast, and 0.6% (3/517) were serological failures. Multivariate analysis demonstrated that older age (>40 years) and lower baseline RPR titer (≤ 1:8) were associated with serofast status. We also identified 21 T. pallidum molecular subtypes among early syphilis patients and detected a new subtype, 14i/a. We found that the proportion of 14i/a type in serofast patients was significantly higher than that in patients with serological cure, predicting an increasing risk of serofast status. Levels of chemerin were higher in the serum of serofast cases than serological cure cases, potentially indicating a novel cytokine marker for serofast in early syphilis patients after therapy. We hope that these results contribute to improve guidelines for the management of syphilis patients who experience serofast.

Abstract
AIM To investigate the risk factors for re-bleeding events in patients with small intestinal vascular malformation and assess the influence of thalidomide on the re-bleeding rate.
METHODS This study involved patients with gastrointestinal bleeding referred to the First Affiliated Hospital of Zhengzhou University for capsule endoscopy (CE) and enteroscopy between January 2012 and December 2014. Only patients with small intestinal vascular malformation were included in the study. Follow-up data were obtained through medical records review, telephone interviews or follow-up clinic visits to identify the risk factors associated with re-bleeding. Based on the follow-up data, the re-bleeding rate was compared between patients who had been treated with thalidomide and those who had not.
RESULTS A total of 156 patients were included in the study, and all of them completed the follow-up, with a mean follow-up duration of 10.78 ± 7.64 mo. Multiple regression analysis identified that presence of hypertension (HR = 1.994, 95%CI: 1.236-3.125, P = 0.005), multiple lesions (≥3) (HR = 1.644, 95%CI: 1.002-2.703, P = 0.049) and liver cirrhosis (HR = 2.116, 95%CI: 1.063-4.212, P = 0.033) were significant independent predictors of re-bleeding, while treatment with thalidomide was a protecting factor (HR = 0.497, 95%CI: 0.303-0.816, P = 0.006). The cumulative re-bleeding rates in patients who were treated with thalidomide and those who were not were 35.71% and 54.65%, respectively, and the difference reached statistical significance (P < 0.05).
CONCLUSION The re-bleeding rate in patients with small bowel vascular malformation is relatively high, especially those with hypertension, multiple lesions (≥3) and liver cirrhosis. Repeated CE or enteroscopy is recommended for those patients with risk factors for re-bleeding within 2 years. Treatment with thalidomide for patients without contraindication can reduce the re-bleeding rate.

Abstract
Seed setting rate is one of the most important components of rice grain yield. To date, only several genes regulating setting rate have been identified in plant. In this study, we showed that laccase-13 (OsLAC13), a member of laccase family genes which are known for their roles in modulating phenylpropanoid pathway and secondary lignification in cell wall, exerts a regulatory function in rice seed setting rate. OsLAC13 expressed in anthers and promotes hydrogen peroxide production both in vitro and in the filaments and anther connectives. Knock-out of OsLAC13 showed significantly increased seed setting rate, while overexpression of this gene exhibited induced mitochondrial damage and suppressed sugar transportation in anthers, which in turn affected seed setting rate. OsLAC13 also induced H2O2 production and mitochondrial damage in the root tip cells which caused the lethal phenotype. We also showed that high abundant of OsmiR397, the suppressor of OsLAC13 mRNA, increased the seed setting rate of rice plants, and restrains H2O2 accumulation in roots during oxidative stress. Our results suggested a novel regulatory role of OsLAC13 gene in regulating seed setting rate by affecting H2O2 dynamics and mitochondrial integrity in rice.

Abstract
Objective: To characterize the clinic features of fulminant type 1 diabetes mellitus(FT1DM). Methods: It was a retrospective study analyzing the clinical and laboratory data of patients diagnosed as FT1DM and type 1 diabetes in the Department of Endocrinology in China-Japan Friendship Hospital from January 2011 to November 2015. Results: A total of 125 newly diagnosed type 1 diabetic patients were included in the study, 14 of them (11.2%) met with the criteria of FT1DM. The age at onset was (35.8±8.3) years. The time from onset to ketosis was 2(0-7) days. The plasma glucose levels were extremely high[ (33.79±14.13)mmol/L], while glycosylated hemoglobin A1c[HbA1c, (6.9±0.7) %]and serum glycosylated albumin [(21.8±4.5)%] levels were only slightly above the normal range. Moreover, the C-peptide levels were extremely low and the situation kept after one month to two years' follow-up. Four (28%) patients were glutamic acid decarboxylase antibody (GADA) positive at the onset with two turned negative. One patient was GADA negative at the onset and turned positive after one month. The levels of serum transaminases increased with enlargement of liver in one of the patients after insulin therapy, who was diagnosed as glycogenic hepatopathy. Conclusions: FT1DM is an extremely rapidly progressing type of diabetes and life threatening disease. Causations have to be taken in medical practice.

Abstract
Hepatitis B virus (HBV) causes acute and chronic hepatitis, and is one of the major causes of cirrhosis and hepatocellular carcinoma. Accumulating evidence suggests that inflammation is the key factor for liver cirrhosis and hepatocellular carcinoma. MicroRNAs play important roles in many biological processes. Here, we aim to explore the function of microRNAs in the HBX-induced inflammation. First, microarray experiment showed that HBV+ liver samples expressed higher level of miR-203a compared to HBV- liver samples. To verify these alterations, HBx-coding plasmid was transfected into HepG2 cells to overexpress HBx protein. The real-time PCR results suggested that over-expression of HBx could induce up-regulation of miR-203a. To define how up-regulation of miR-203a can induce liver cells inflammation, we over-expressed miR-203a in HepG2 cells. Annexin V staining and BrdU staining suggested that overexpression of miR-203a significantly increased the cell apoptosis and proliferation, meanwhile, over-expression of miR-203a could lead to a decrease in G0/G1 phase cells and an increase in G2/M phase cells. Some cytokines production including IL-6 and IL-8 were significantly increased, but TGFβ and IFNγ were decreased in miR-203a over-expressed HepG2 cells. Luciferase reporter assay experiments, protein mass-spectrum assay and real-time PCR all together demonstrated that Rap1a was the target gene of miR-203a. Further experiments showed that these alterations were modulated through PI3K/ERK/p38/NFκB pathways. These data suggested that HBV-infection could up-regulate the expression of miR-203a, thus down regulated the expression of Rap1a and affected the PI3K/ERK/p38/NFκB pathways, finally induced the hepatitis inflammation.

Abstract
Objective: To analyze the epidemiological characteristics of hospitalized children with severe burn from several regions in China during 3 years, so as to provide evidence for prevention of burns in children. Methods: Relying on the entry system of epidemiology data and biological sample of severe burn from multicenter in clinic, medical records of children with severe burn, aged 18 and under, hospitalized in 6 burn wards from February 2012 to February 2015 were collected. The children were divided into 5 age brackets: less than or equal to 1 year old, more than 1 year old and less than or equal to 3 years old, more than 3 years old and less than or equal to 6 years old, more than 6 years old and less than or equal to 12 years old, more than 12 years old and less than or equal to 18 years old. Meanwhile the children were divided into rural and urban children according to their residences. Data of gender and residence of children in the 5 age brackets, cause of injury, location of injury, total burn area, wound site, inhalation injury and combined injury, and source of hospitalization expenses of children in the 5 age brackets and two types of residence, and outcome and length of hospital stay of the children were analyzed. The cause of injury of children in different location of injury was analyzed. In addition, they were divided into 2 age brackets: less than or equal to 6 years old and more than 6 years old and less than or equal to 18 years old, and then incidences of hand and foot burn injury were compared. Data were processed with chi-square test, and the correlation between age and total burn area was processed with Spearman correlation analysis. Results: Four hundred and forty out of 1 106 inpatients with severe burn were children, accounting for 39.8% who were included in the system. (1) The majority of children were male (270, 61.4%). The number of children more than 1 year old and less than or equal to 3 years old ranked the first (222, 50.5%) in the 5 age brackets. The ratio of children from rural areas to that from urban areas was 2.9∶1.0. There were no statistically significant differences in both gender and residence of children among the 5 age brackets (with χ2 values respectively 7.649 and 9.399, P values above 0.05). (2) Scald was the most common cause of burn. There was statistically significant difference in injury cause of children among the 5 age brackets (χ2=136.307, P<0.001). There was no statistically significant difference in injury cause of children among the two types of residence (χ2=5.164, P>0.05). (3) Private house was the most common location of injury. There was statistically significant difference in location of injury of children among the 5 age brackets (χ2=124.930, P<0.001). There was no statistically significant difference in location of injury of children among the two types of residence (χ2=3.364, P>0.05). There was statistically significant difference in injury cause of children in different location of injury (χ2=118.284, P<0.001). (4) Most of children were with total burn areas from 10% to 39% total body surface area. There was statistically significant difference in total burn area of children among the 5 age brackets (χ2=103.568, P<0.001). There was positive correlation between age and total burn area (r=0.177, P<0.001). There was no statistically significant difference in total burn area of children among the two types of residence (χ2=16.213, P>0.05). (5) Trunk, lower extremity, and upper extremity were the most common wound sites, respectively. There was statistically significant difference in wound site of children among the 5 age brackets (χ2=45.674, P=0.019). There was statistically significant difference in incidence of hand and foot burn between children less than or equal to 6 years old and children more than 6 years old and less than or equal to 18 years old (with χ2 values respectively 29.188 and 14.612, P values below 0.01). There was no statistically significant difference in wound site of children among the two types of residence (χ2=8.515, P>0.05). (6) Twenty-seven children suffered inhalation injury. The main age bracket was more than 12 years old and less than or equal to 18 years old (8 children). The main residence was rural area (18 children). The main cause of inhalation injury was flame burn (23 children). Nine children suffered combined injury, among which the children more than 12 years old and less than or equal to 18 years old accounted for the highest ratio (5 children), and the urban children accounted for higher ratio (5 children). (7) Among the 437 children, most of their hospitalization expenses were at their own expense. There was statistically significant difference in the source of hospitalization expenses of children among the 5 age brackets (χ2=17.917, P=0.001). There was no statistically significant difference in the source of hospitalization expenses of children among the two types of residence (χ2=0.749, P>0.05). (8) Among the 437 children, 34 children abandoned treatment and were discharged from hospital, attributed to lack of funding. Seventy-eight children were discharged with a better health condition and 347 were cured. The condition of 6 children worsened and 6 children died. Mean length of hospital stay was 28.6 days for all the children, and 8.8 days for the deteriorated and dead children. Conclusions: Children were the major group of patients with severe burn in China. Male children less than or equal to 6 years old were common with scald as the major cause of injury, private house as the major location of injury, and trunk, lower and upper extremity as the most common wound sites, their own expenses as the major source of hospitalization expenses. There were statistically significant differences in cause of injury, location of injury, total burn area, wound site, and hospitalization expenses source of children among the 5 age brackets.

Abstract
OBJECTIVE To observe and primarily evaluate the feasibility and validity of continuous blood purification (CBP) during the early stage of severe burn. METHODS Forty-one patients with severe burn admitted to our ward from January 2013 to July 2015, conforming to the study criteria, were divided into conventional treatment group (CT, n=21) and blood purification group (BP, n=20) according to the random number table and patient's personal consent. Patients in group CT received CT conforming to the traditional resuscitation principle for severe burn, while patients in group BP received CT and blood purification treatment in the mode of continuous venous-venous hemodiafiltration in addition up to post injury hour (PIH) 72. On post injury day (PID) 1, 2, 3, the vital signs, volume of fluid input, and volume of the urine output were observed and recorded; femoral artery blood was drawn to determine lactate, bicarbonate radical, and base excess, and oxygen index was calculated. At PIH 12, 24, 48, 72, femoral vein blood was drawn to determine white cell count, platelet count, neutrophils, creatine kinase-MB, creatine kinase, lactic dehydrogenase, aspartate transaminase (AST), alanine aminotransferase (ALT), creatinine, urea nitrogen, and blood glucose (the ratio of AST to ALT was calculated). The incidence of infection, sepsis, and multiple organ dysfunction syndrome (MODS) and the mortality of patients were recorded during 2 months after injury. Data were processed with chi-square test, analysis of variance for repeated measurement, t test and Wilcoxon test, and the values of P were adjusted by Bonferroni. RESULTS The observation was completed in the 41 patients without exclusion. (1) There were no statistically significant differences in vital signs, volume of fluid input, and volume of the urine output of patients between two groups on PID 1, 2, 3 (with t values from -1.64 to 1.48, P values above 0.05). (2) Compared with that in group CT, the level of lactate of patients in group BP declined significantly on PID 2 and 3 (with Z values respectively -2.37 and -2.46, P values below 0.05). Compared with those in group CT, the levels of bicarbonate radical and base excess of patients in group BP declined significantly on PID 3 (with t values both as -2.51, P values below 0.05). The oxygen index of patients in group BP on PID 3 was (370±98) mmHg (1 mmHg=0.133 kPa), which was significantly higher than that in group CT [(305±81) mmHg, t=2.27, P<0.05]. (3) There were no statistically significant differences in white cell count, platelet count, neutrophils, creatine kinase, lactic dehydrogenase, AST, ALT, and AST to ALT ratio of patients between two groups at PIH 12, 24, 48, 72 (with t values from -1.47 to 1.19, Z values from -1.58 to -0.03, P values above 0.05). At PIH 24, 48, 72, the levels of creatine kinase-MB and blood glucose of patients in group BP were respectively (81±43), (55±34), (58±40) U/L and (7.9±2.0), (6.7±0.9), (6.9±1.8) mmol/L, which were significantly lower than those in group CT [(179±184), (124±71), (103±57) U/L and (10.1±3.8), (9.1±2.4), (8.8±4.1) mmol/L, with Z values from -3.73 to -2.02, P<0.05 or P<0.01]. Compared with those of patients in group CT, creatinine at PIH 48 and urea nitrogen at PIH 24, 48, 72 were obviously lower in group BP (with t values from -4.23 to -2.44, P<0.05 or P<0.01). (4) During the two months after injury, the infection rate of patients in group BP was 60.0% (12/20), which was significantly lower than that in group CT [95.2% (20/21), χ(2)=5.51, P<0.05]. The incidence of sepsis and MODS and the mortality of patients in group BP were all lower than those in group CT, but there were no statistically significant differences (with χ(2) values from 0.22 to 2.93, P values above 0.05). CONCLUSIONS Conducting CBP in the early stage of severe burn is safe and feasible, which does not obviously affect the vital signs, volumes of fluid input and urine output, or platelet count of patients, additionally, it could help protect the function of vital organs, eliminate stress hyperglycemia, and reduce infection rate.

Abstract
BACKGROUND The aim of the present study was to investigate whether the therapeutic efficacy of acarbose and metformin is correlated with baseline HbA1c levels in Chinese patients with newly diagnosed type 2 diabetes mellitus (T2DM). METHODS Data for 711 subjects were retrieved from the MARCH (Metformin and AcaRbose in Chinese as initial Hypoglycemic treatment) trial database and reviewed retrospectively. Patients were grouped according to baseline HbA1c levels (<7%, 7%-8%, and >8%) and the results for these three groups were compared between acarbose and metformin treatments. RESULTS Acarbose and metformin treatment significantly improved T2DM-associated parameters (weight, fasting plasma glucose [FPG], postprandial glucose [PPG], glucagon-like peptide-1 [GLP-1], HOMA-IR, and total cholesterol) across all HbA1c levels. Acarbose decreased PPG and HOMA-β significantly more than metformin, but only in subjects with lower baseline HbA1c (PPG in the <7% and 7%-8%, HOMA-β in the <7% groups; all P < 0.05). Acarbose decreased triglyceride (TG) levels, and the areas under the curve (AUC) for insulin and glucagon more than metformin at all HbA1c levels (P < 0.05). After 24 weeks treatment, metformin decreased FPG levels significantly more than acarbose for all baseline HbA1c groups (all P < 0.001). With the exception of FPG, PPG, and TG levels, differences between the two treatment groups observed at 24 weeks were not detected at 48 weeks. CONCLUSIONS Acarbose decreased PPG and TG and spared the AUC for insulin more effectively in patients with low-to-moderate baseline HbA1c levels, whereas metformin induced greater reductions in FPG. These results may help guide selection of initial therapy based on baseline HbA1c.

Abstract
Objective This study investigated clinical and pathological characteristics and risk factors in papillary thyroid carcinoma (PTC) patients’ native to Yunnan plateau in southwestern China. Methods Clinical data from 1,198 patients diagnosed with PTC (n=578) and control subjects (n=620) with benign thyroid disease (ie, thyroid nodule disease, benign thyroid diseases [BTD]) in Yunnan province were analyzed retrospectively. Results The mean patient age was lower for PTC than for BTD. Positive ratios of thyroid peroxidase antibody, thyroglobulin antibody (TGAb), and thyrotrophin receptor antibody (TRAb) were higher in PTC than in BTD patients. The ratio of PTC coexisting with Hashimoto’s thyroiditis (HT) or with lymphocytic thyroiditis was higher than that of BTD. The number of patients whose age at menarche was ≤13 years, who had given birth to less than or equal to two children, or who were in premenopause were higher in the PTC than in the BTD group. Multivariate conditional logistic regression analyses revealed that age >45 years, nodal size >1 cm, and elevated TG levels were protective factors against PTC. Abnormally elevated TGAb and TRAb levels were independent risk factors for PTC in females. Conclusion HT was not an independent risk factor for but was associated with PTC. TRAb is a risk factor for PTC in individuals living in the Yunnan plateau, but not for those in the plains region.

Abstract
AIM: To examine the expression of BANCR, E-cadherin and Vimentin in hepatocellular carcinoma (HCC) and to analyze their relationship with clinicopathological status of HCC patients.
METHODS: The expression of BANCR was studied in 108 HCC tissues and adjacent non-tumor tissues by using quantitative real-time-PCR, and its correlation with clinical parameters was analyzed. E-cadherin (an epithelial biomarker) and Vimentin (a mesenchymal biomarker) expression was evaluated by immunocytochemistry.
RESULTS: BANCR expression in HCC tissues was significantly increased compared with that in adjacent non-tumor tissues (P < 0.05). High expression of BANCR was associated with lymph node metastasis (P = 0.001) and TNM stage (P = 0.000), but not with age, gender, tumor size, α-fetoprotein, Edmondson-Steiner grade, tumor number, or vascular invasion (P > 0.05). There was an inverse correlation between BANCR and E-cadherin expression and a positive correlation between BANCR and Vimentin expression in HCC tissues.
CONCLUSION: BANCR is highly expressed in HCC tissues and it may play crucial roles in the invasion and metastasis of HCC. BANCR expression is correlated with E-cadherin and Vimentin expression in HCC.

Abstract
AIM: To evaluate the clinicopathologic characteristics of interval gastric cancer (IGC) and the optimal frequency of endoscopy for gastric cancer screening.
METHODS: A retrospective analysis was performed of 41 patients with interval gastric cancer treated at the First Affiliated Hospital of Zhengzhou University from January 1, 2012 to December 31, 2014. We compared the differences between the missed cancers and the latent cancers.
RESULTS: A total of 41 IGC patients were identified, with a mean age of 52.56 years ± 10.60 years and a mean interval time of 18.9 mo. There were 33 IGC patients with poorly differentiated adenocarcinoma (80.5%), 18 IGC patients with tumor located in the gastric antrum (43.9%), and 24 IGC patients exhibited endoscopic ulcer morphology (58.5%).
CONCLUSION: IGCs tend to be poorly differentiated, located in gastric antrum and exhibit endoscopic ulcer morphology. The optimal frequency of endoscopy for gastric cancer screening may be 3 years. The patients with missed cancer are generally younger than the patients with latent cancer.

Abstract
This study was aimed to investigate clinical features of Chinese metabolic syndrome (MS) subjects with normal urinary albumin to creatinine ratio (UACR) and to estimate independent correlation factor for UACR. Data were drawn from a cross-sectional survey in participants having MS. The patients with different grade of albuminuria were divided into 4 groups according to the value of UACR (<10, 10-20, 21-30, >30 mg/g). All underwent biochemical tests. Bioelectrical impedance body fat content, islet β-cell function and insulin sensitivity were measured. Multivariable linear regression models were applied to further determine association between UACR and clinical factors with adjustment. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), TG, fat mass, fat content and homeostasis model assessment for insulin resistance (HOMA-IR) were significantly higher in the group with UACR at 10-20 mg/g than those in the group with UACA lower than 10 mg/g (P<0.05). Multivariable linear regression showed that TG, HbA1c, waist-hip ratio (WHR) and SBP were independently associated with UACR. The patients with normal UACR had abnormal levels of MS components. The factors independently associated with UACR were TG, HbA1c, WHR and SBP.

Abstract
OBJECTIVES The purpose of this study was to investigate the diagnostic value of 3-dimensional (3D) speckle-tracking echocardiography for estimating left ventricular filling pressure in patients with coronary artery disease (CAD) and a preserved left ventricular ejection fraction. METHODS Altogether, 84 patients with CAD and 30 age- and sex-matched healthy control participants in sinus rhythm were recruited prospectively. All participants underwent conventional and 3D speckle-tracking echocardiography. Global strain values were automatically calculated by 3D speckle-tracking analysis. The left ventricular end-diastolic pressure (LVEDP) was determined invasively by left heart catheterization. Echocardiography and cardiac catheterization were performed within 24 hours. RESULTS Compared with the controls, patients with CAD showed lower global longitudinal strain, global circumferential strain, global area strain, and global radial strain. Patients with CAD who had an elevated LVEDP had much lower levels of all 4 3D-speckle-tracking echocardiographic variables. Pearson correlation analysis revealed that the LVEDP correlated positively with the early transmitral flow velocity/early diastolic myocardial velocity (E/E') ratio, global longitudinal strain, global circumferential strain, and global area strain. It correlated negatively with global radial strain. Receiver operating characteristic curve analysis revealed that these 3D speckle-tracking echocardiographic indices could effectively predict elevated left ventricular filling pressure (LVEDP >15 mm Hg) in patients with CAD (areas under the curve: global longitudinal strain, 0.78; global radial strain, 0.77; global circumferential strain, 0.75; and global area strain, 0.74). These parameters, however, showed no advantages over the commonly used E/E' ratio (area under the curve, 0.84). CONCLUSIONS Three-dimensional speckle-tracking echocardiography was a practical technique for predicting elevated left ventricular filling pressure, but it might not be superior to the commonly used E/E' ratio in patients with CAD who have a normal left ventricular ejection fraction.

Abstract
This study aimed to explore the clinical value of the CD4(+) T cell ATP levels in patients with renal cell carcinoma through the application of the ImmuKnow(TM)-Cylex(®) assay. We recruited 104 patients with renal cancer who had undergone surgery at Fuzhou General Hospital from March 2009 to June 2012, and were subsequently treated by dendritic cell and cytokine-induced killer cell bio-therapy or interferon-α therapy. The changes in CD4(+) T cell ATP levels were detected at the perioperative period and at 10 days, 1 month, 3 months, and 1 year after the surgery using the ImmuKnow assay. In addition, the differences in ATP levels in different therapy groups were compared and the prognosis conditions were analyzed. Our results demonstrated that no significant difference in the ATP levels occurred at different time points; furthermore, there were no obviously different ATP levels between the different therapy groups, and the ATP levels were found to have no clinical significance for the assessment of renal cancer prognosis. Overall, this study suggested that CD4(+) T cell ATP levels as detected by the ImmuKnow assay have no obvious clinical value in patients with renal cancer.

Abstract
AIM: To detect the expression of eosinophil chemotactic factor-3 (Eotaxin-3) in eosinophilic gastroenteritis (EG) and investigate the effect of glucocorticoid on Eotaxin-3 expression.
METHODS: Forty-eight patients with EG and 24 healthy controls were included. Patients with EG were equally divided into two groups, a placebo group and a prednisone group. Eotaxin-3 expression was measured by enzyme-linked immunosorbent assay in the serum and tissue samples of all subjects.
RESULTS: The expression levels of Eotaxin-3 in serum and tissue were significantly elevated in the EG group compared to normal controls (P < 0.05). Eotaxin-3 in serum and tissue significantly decreased after treatment (P < 0.05), although its change had no significance in the placebo group. A positive correlation was observed between eosinophil (Eos) count and Eotaxin-3 in serum and tissue in the EG group.
CONCLUSION: Eotaxin-3 may be involved in the pathophysiological process of EG. Hormone therapy may inhibit the expression of Eotaxin-3. Serum Eotaxin-3 may be used as a non-invasive index for evaluating the treatment effect in EG.

Abstract
In order to study the genetic diversity and taxonomic status of Gymnocypris chilianensis on a molecular level, the mitochondrial DNA cytochrome b gene was sequenced for 74 individuals of G. chilianensis from two locations (Heihe River and Shule River) and 42 individuals of its affinis species Gymnocypris przewalskii. Analyses of genetic diversity and sequence differences were conducted for these samples, combined with the analysis of 30 homologous sequences of another affinis species Gymnocypris eckloni, which were downloaded from GenBank. The results showed that both the haplotype diversity (h = 0.9820) and nucleotide diversity (π= 0.0039) of the Shule River G. chilianensis were lower than the other populations, thus, the Shule River G. chilianensis should be prioritized for protection because of its lower genetic diversity level. The results of sequence analysis showed that the genetic distance between the Heihe River G. chilianensis population and the Shule River G. chilianensis population was 0.0064, and the genetic distance between these two populations and the G. przewalskii population was 0.0838 and 0.0810, respectively. The genetic distance between the two G. chilianensis populations and the G. eckloni population was 0.0805 and 0.0778, respectively. Analysis of sequence differences indicates that G. chilianensis is sufficiently diverged from G. przewalskii and G. eckloni to the extent that it has reached species level, thus, G. chilianensis can be considered an independent species of Gymnocypris.

Abstract
Bone marrow mesenchymal stromal cells (BMSCs) have potential applications in cell and gene therapies for cardiac disease. The cardiac-specific transcription factors GATA-binding protein 4 (GATA4) and T-Box protein 5 (TBX5) are considered to be pivotal in cardiogenesis. The aim of this study was to investigate the effects of GATA4 and TBX5 on cardiomyogenic differentiation of BMSCs. The BMSCs were initially isolated and identified. Vectors harboring cardiac transcription factor genes GATA4 and TBX5 or empty vectors were transferred into BMSCs. Cardiomyogenic cells differentiated from BMSCs were identified by expression of cardiac-specific markers including cardiac troponin T, connexin 43, β-myosin heavy chain, and myosin light chain-2 using immunocytochemical staining, western blotting, and quantitative real-time PCR. The ultrastructures of the differentiated cells were examined by transmission electron microscopy, which were similar to those of fetal cardiomyocytes. The differentiated cells exhibited L-type calcium current activities reflective of the electrophysiological characteristics of cardiomyocytes. These findings indicate that exogenous expression of cardiac-specific transcription factors GATA4 and TBX5 enhance cardiomyogenic differentiation of BMSCs.

Abstract
AIM: To analyze the hepatitis B virus (HBV) characters in China, as well as the correlation between several HBV mutation and hepatitis symptoms.
METHODS: A total of 1148 HBV genome sequences from patients throughout China were collected via the National Center For Biotechnology Information database (information including: genotype, territory and clinical status). HBV genotypes were classified by a direct reference from the Genbank sequence annotation, phylogenetic tree and online software analysis (http://www.ncbi.nlm.nih.gov/projects/genotyping/formpage.cgi). The phylogenetic tree was constructed based on the neighbor-joining method by MEGA5.0 software. HBV sequences were grouped based on phylogenetic tree and the distance between the groups was calculated by using the computer between group mean distance methods. Seven hundred and twelve HBV sequences with clear annotation of clinical symptoms were selected to analyses the correlation of mutation and clinical symptoms. Characteristics of sequences were analyzed by using DNAStar and BioEdit software packages. The codon usage bias and RNA secondary structures analysis were performed by RNAdraw software. Recombination analysis was performed by using Simplot software.
RESULTS: In China, HBV genotype C was the predominant in Northeastern, genotype B was predominant in Central Southern areas, genotype B and C were both dominant in Southwestern areas, and the recombinant genotype C/D was predominant in Northwestern areas. C2 and B2 were identified as the two major sub-genotypes, FJ386674 might be a putative sub-genotype as B10. The basal core promoter double mutation and pre-C mutation showed various significant differences between hepatitis symptoms. In addition to ATG, many other HBV initiation codons also exist. HBV has codon usage bias; the termination codon of X, C and P open reading frames (ORF) were TAA, TAG, and TGA, respectively. The major stop codons of S-ORF were TAA (96.45%) and TGA (83.60%) in B2 and C2 subtype, respectively.
CONCLUSION: This study recapitulated the epidemiology of HBV in China, and the information might be meaningful critical for the future prevention and therapy of HBV infections.

Abstract
BACKGROUND Human toll-like receptor 4 (TLR4) is an important receptor in innate immunity, particularly against gram-negative bacterial infection (GNBI). In our study, we evaluated associations of TLR4 single nucleotide polymorphisms (SNPs) with GNBI in Han Chinese neonates. PATIENTS AND METHODS Polymorphisms in TLR4 were genotyped in 201 neonates with GNBI and 279 gestational age and birth weight-matched controls without GNBI. Polymorphism analyses were applied to allele frequencies of the detected TLR4 SNPs and their associations with various clinical entities, including premature birth and GNBI were assessed. RESULTS A total of six SNPs with more than 5% frequency were found in several promoter sequences, including rs10759931, rs2737190, rs10116253, rs10983755, rs1927914, and rs10759932. Mutation allele frequencies ranged from 23 to 41%. There were no SNPs with a frequency greater than 5% in exon analyses. Allele G rs2737190 mutations and GGCGGC haplotypes were more frequent among preterm GNBI neonates (odds ratio [OR], 1.32; 95% confidence interval [CI], 1.02-1.71 and OR, 1.89; 95% CI, 1.19-3.00, respectively). No specific alleles or haplotypes were associated with GNBI status among term neonates. CONCLUSION In this study population of Han Chinese, there was a significant association between an ethnical unique SNP in the TLR4 promoter region and preterm neonatal GNBIs.

Abstract
There is a dearth of data about the prevalence of hepatitis B virus (HBV) infection in Mengla, China; and no detailed analysis of the molecular evolution of genotype I in Asia. In this study, 909 serum samples from ethnic minority people in China were obtained. Serological assay and HBV S-gene amplification were carried out, and phylogenetic and evolutionary dynamics analysis of 62 HBV/I S-gene was performed. On this survey, 153 individuals were tested HBsAg-positive. Genotypes of S-gene were classified into three groups: C, B and I. Under the strict model and the relax model, the estimated evolutionary rates for HBV/I were 3.74 × 10(-4) and 6.93 × 10(-4) substitution/site/year, respectively. However, when the geographic origin was taken into account, the mean substitution rates were increased. Estimated time to most recent ancestor of genotype I varied from ~30 to ~70 years ago. The Bayesian sky plot showed a rapid spread of HBV/I at the end of 1980s. Peculiar nucleotides distributed were observed in the subgenotype I1/I2. In conclusion, higher prevalence of HBV infection was observed in Mengla county. Multifactors like timescale and spatial locations should be integrated to provide a better interpretation of the HBV/I evolutionary history in the region.

Abstract
AIM: To explore the significance of serum sCD25 level in the diagnosis of hepatocellular carcinoma (HCC).
METHODS: A total of 160 subjects, including 40 patients with HCC, 40 patients with liver cirrhosis, 40 patients with chronic hepatitis B, and 40 healthy controls, were measured for serum sCD25 levels by enzyme-linked immuno sorbent assay (ELISA).
RESULTS: Serum sCD25 level in the HCC group (mean, 9641.23 pg/mL) was significantly higher than those in the cirrhosis group, chronic hepatitis B group and healthy control group (P < 0.05). Serum sCD25 level demonstrated a better sensitivity than alpha fetal protein (AFP) in the diagnosis of HCC.
CONCLUSION: Serum sCD25 level is effective in the detection of early HCC, and it may serve as a novel predictive marker of HCC to distinguish advanced cirrhosis from early HCC.
