Abstract
Lupus nephritis is the most common complication of systemic lupus erythematosus (SLE) and an important cause of end-stage kidney disease and death in patients with SLE. The pathogenesis of SLE is complex, with no effective treatment and poor long-term prognosis. The development of genomic medicine provides a new way to explore the disease-causing genes and pathogenesis of lupus nephritis. Here, the article introduces how to uncover the pathogenesis of lupus nephritis from the genome level and explore new strategies for diagnosis and treatment on this disease.

Abstract
Objective: To investigate respiratory virus infection in children with septic shock in pediatric care units (PICU) in China and its influence on clinical outcomes. Methods: The clinical data of children with septic shock in children's PICU from January 2018 to December 2019 in 10 Chinese hospitals were retrospectively collected. They were divided into the pre-COVID-19 and post-COVID-19 groups according to the onset of disease, and the characteristics and composition of respiratory virus in the 2 groups were compared. Matching age, malignant underlying diseases, bacteria, fungi and other viruses, a new database was generated using 1∶1 propensity score matching method. The children were divided into the respiratory virus group and non-respiratory virus group according to the presence or absence of respiratory virus infection; their clinical characteristics, diagnosis, and treatment were compared by t-test, rank sum test and Chi-square test. The correlation between respiratory virus infection and the clinical outcomes was analyzed by logistic regression. Results: A total of 1 247 children with septic shock were included in the study, of them 748 were male; the age was 37 (11, 105) months. In the pre-and post-COVID-19 groups, there were 530 and 717 cases of septic shock, respectively; the positive rate of respiratory virus was 14.9% (79 cases) and 9.8% (70 cases); the seasonal distribution of septic shock was 28.9% (153/530) and 25.9% (185/717) in autumn, and 30.3% (161/530) and 28.3% (203/717) in winter, respectively, and the corresponding positive rates of respiratory viruses were 19.6% (30/153) and 15.7% (29/185) in autumn, and 21.1% (34/161) and 15.3% (31/203) in winter, respectively. The positive rates of influenza virus and adenovirus in the post-COVID-19 group were lower than those in the pre-COVID-19 group (2.1% (15/717) vs. 7.5% (40/530), and 0.7% (5/717) vs. 3.2% (17/530), χ2=21.51 and 11.08, respectively; all P<0.05). Rhinovirus virus were higher than those in the pre-Covid-19 group (1.7% (12/717) vs. 0.2% (1/530), χ2=6.51, P=0.011). After propensity score matching, there were 147 cases in both the respiratory virus group and the non-respiratory virus group. Rate of respiratory failure, acute respiratory distress, rate of disseminated coagulation dysfunction, and immunoglobulin usage of the respiratory virus group were higher than those of non-respiratory virus group (77.6% (114/147) vs. 59.2% (87/147), 17.7% (26/147) vs. 4.1% (6/147), 15.6% (25/147) vs. 4.1% (7/147), and 35.4% (52/147) vs. 21.4% (32/147); χ2=11.07, 14.02, 11.06 and 6.67, all P<0.05); and PICU hospitalization of the former was longer than that of the later (7 (3, 16) vs. 3 (1, 7)d, Z=5.01, P<0.001). Univariate logistic regression analysis showed that the presence of respiratory viral infection was associated with respiratory failure, disseminated coagulation dysfunction, the use of mechanical ventilation, and the use of immunoglobulin and anti-respiratory viral drugs (OR=2.42, 0.22, 0.25, 0.56 and 1.12, all P<0.05). Conclusions: The composition of respiratory virus infection in children with septic shock is different between pre and post-COVID-19. Respiratory viral infection is associated with organ dysfunction in children with septic shock. Decreasing respiratory viral infection through respiratory protection may improve the clinical outcome of these children.

Abstract
As a crucial component of neuromorphic chips, on-chip memory usually occupies most of the on-chip resources and limits the improvement of neuron density. The alternative of using off-chip memory may result in additional power consumption or even a bottleneck for off-chip data access. This article proposes an on- and off-chip co-design approach and a figure of merit (FOM) to achieve a trade-off between chip area, power consumption, and data access bandwidth. By evaluating the FOM of each design scheme, the scheme with the highest FOM (1.085× better than the baseline) is adopted to design a neuromorphic chip. Deep multiplexing and weight-sharing technologies are used to reduce on-chip resource overhead and data access pressure. A hybrid memory design method is proposed to optimize on- and off-chip memory distribution, which reduces on-chip storage pressure and total power consumption by 92.88% and 27.86%, respectively, while avoiding the explosion of off-chip access bandwidth. The co-designed neuromorphic chip with ten cores fabricated under standard 55 nm CMOS technology has an area of 4.4 mm 2 and a core neuron density of 4.92 K/mm 2, an improvement of 3.39 ∼ 30.56× compared with previous works. After deploying a full-connected and a convolution-based spiking neural network (SNN) for ECG signal recognition, the neuromorphic chip achieves 92% and 95% accuracy, respectively. This work provides a new path for developing high-density and large-scale neuromorphic chips.

Abstract
Many efforts have been made to improve the neuron integration efficiency on neuromorphic chips, such as using emerging memory devices and shrinking CMOS technology nodes. However, in the fully connected (FC) neuromorphic core, increasing the number of neurons will lead to a square increase in synapse & dendrite costs and a high-slope linear increase in soma costs, resulting in an explosive growth of core hardware costs. We propose a co-designed neuromorphic core (SRCcore) based on the quantized spiking neural network (SNN) technology and compact chip design methodology. The cost of the neuron/synapse module in SRCcore weakly depends on the neuron number, which effectively relieves the growth pressure of the core area caused by increasing the neuron number. In the proposed BICS chip based on SRCcore, although the neuron/synapse module implements 1∼16 times of neurons and 1∼66 times of synapses, it only costs an area of 1.79 × 107 F2, which is 7.9%∼38.6% of that in previous works. Based on the weight quantization strategy matched with SRCcore, quantized SNNs achieve 0.05%∼2.19% higher accuracy than previous works, thus supporting the design and application of SRCcore. Finally, a cross-modeling application is demonstrated based on the chip. We hope this work will accelerate the development of cortical-scale neuromorphic systems.

Abstract
Objective: To analyze the clinical features and surgical outcomes of petrous bone cholesteatomas (PBCs). Methods: Data from 39 PBCs patients treated in the Department of Otorhinolaryngology, Xijing Hospital from September 2011 to December 2017 were reviewed retrospectively, including 23 males, 16 femals, aged 12-71 years old, with the median age of 37. Clinical classifications, surgical methods, facial and hearing function, and intraoperative and postoperative complications were made summary analysis. Results: In this study, five patients were congenital PBCs and 34 patients were acquired PBCs. The common clinical symptoms were hearing loss (100%, 39/39), ear discharge/pus (89.7%, 35/39) and facial paralysis (46.2%, 18/39). According to Sanna's classification, 14 cases were supralabyrinthine, including three cases underwent transcochlear (TC) approach, six cases underwent transotic (TO) approach and five underwent translabyrinthine (TL) approach. 10 cases were infralabyrinthine, including eight cases underwent subtotal petrosectomy, one case underwent TO approach and one underwent TL approach.10 cases were massive, including seven cases underwent TC approach, three cases underwent TO approach. Five cases were infralabyrinthine-apical, including two cases underwent TC approach, two cases underwent TO approach, and one case underwent endoscope assisted infratemporal fossa type B. The degree of facial nerve (FN) dysfunction from high to low was massive (6/10), supralabyrinthine (8/14), infralabyrinthine-apical (2/5) and infralabyrinthine (2/10). 19 cases involved in facial nerve operation, three cases underwent FN decompression, four cases underwent FN rerouting, four cases underwent nerve grafting, and one case underwent facial-hypoglossal anastomosis. Preoperative FN involvement in 18 cases, and the FN function was improved in 14 cases after surgery. The improved rate of postoperative FN function was 77.8%. The bone conducted hearing retained 50.0% (14/28) postoperatively. Five cases with cerebrospinal fluid leak were managed by inserting free muscle plugs and cavity obliteration. Two cases with the cholesteatomas matrix involved the sigmoid sinus and the jugular bulb, and occlusion of the sigmoid sinus was performed. Postoperatively, two patients presented with synkinesis. The patients were followed up for 40 to 115 months, and there was no recurrence. Conclusions: There are no specific clinical manifestations for PBCs, thus, it is difficult in early diagnosis and treatment. According to Sanna's classification, preoperative FN and hearing function, the best surgical approach should be selected with minimal recurrences and perioperative morbidity.

Abstract
Objective: To examine the long-term efficacy of radiofrequency closure in the treatment of great saphenous vein varicose. Methods: The clinic data of 185 patients with varicose veins of lower limbs treated with radiofrequency closure admitted at Department of Vascular Surgery, Beijing Shijitan Hospital, Capital Medical University from July 2016 to January 2017 was analyzed retrospectively. A total of 203 limbs were treated by radiofrequency closure. The long-term efficacy of radiofrequency closure was evaluated by analyzing the closure rate, clinical-etiology- anatomy-pathophysiology (CEAP) grading, venous clinical severity score (VCSS), chronic venous insufficiency questionnaire (CIVIQ) score, and complications, using repeated measures analysis of variance. Results: All procedures were successful. The closure rate was 98.0% (199/203) at one year and two years postoperative, which was still maintained at 97.5% (198/203) at 3 years of follow-up. Postoperative CEAP grading was significantly downgraded compared with that before the operation. Totally 88.4% (76/86) of C5 to C6 grade patients downgraded to C2 to C4 grade at 6 months, and 95.3% (82/86) downgraded to C0 to C2 garde at 3 years postoperative. VCSS and CIVIQ score in both groups significantly improved at all follow-up time points compared to preoperative scores (VCSS: F=1 064.7, P=0.003; CIVIQ score: F=2 984.3, P=0.001). The most common complication was subcutaneous blood stasis (10.8%), most of which disappeared within 1 month after the surgery.

Abstract
OBJECTIVE This paper presents a newborn (G2P2, gestational age of 39+6 weeks, birth weight of 3,200 g, with normal fetal amniotic fluid) with suspected coronavirus disease 2019 (COVID-19) admitted to our hospital on February 10, 2020, at the birth age of 16 hours and 34 minutes. The Apgar scores at 1 and 5 min were 9 and 10 points, respectively. PATIENTS AND METHODS The mother of the newborn was exposed to a patient with COVID-19 five days before delivery. The newborn had nausea and vomiting after birth, with feeding intolerance, and full enteral feeding was given on the 6th day after birth. The newborn was in good general condition during the period of hospitalization. RESULTS The two 2019-nCoV nucleic acid tests of the newborn were negative on the 5th and 7th days after birth. On the 1st and 8th days after birth, typical pulmonary lesions were detected in the newborn by chest CT. Our study supports that chest imaging examination should be actively performed in the newborn even with a negative 2019-nCoV nucleic acid test in cases where a pregnant woman is exposed to a patient with COVID-19 or is confirmed with 2019-nCoV infection. CONCLUSIONS For newborns with typical pulmonary lesions, strict quarantine measures are suggested if the possibility of COVID-19 cannot be excluded.

Abstract
OBJECTIVE Breast cancer has been proven as the most common malignancy influencing the health of females. This research aimed to clarify the effects of high-mobility group box 3 (HMGB3)-small interfere RNA (HMGB3-siRNA) on the proliferation of breast cancer cells. MATERIALS AND METHODS HMGB3-mimic and HMGB3-siRNA lentiviral vectors were structured. The above lentiviral vectors were then transfected into normal breast cells (MCF10A) and breast cancer cells (MDA-MB-231). Cell counting kit-8 (CCK-8) analysis was employed to assess proliferative viabilities of cells. The formation of the mammosphere in breast cancer cells was examined using mammosphere-forming assay. The mRNA expression of Nanog, Sox2, and OCT-4 genes was evaluated using quantitative real time-PCR (qRT-PCR). CD44 positive/CD24 negative (CD44+/CD24-) cell levels were evaluated using flow cytometry assay. The correlation between HMGB3 and hypoxia-inducible factor 1α (HIF1α) was analyzed using Linear-Regression analysis. The interaction between HMGB3 and HIF1α expression was determined using the Dual-Luciferase assay. RESULTS HMGB3 expression was remarkably enhanced in breast cancer cells compared to that in normal cells (p<0.05). HMGB3-siRNA significantly decreased the proliferative activity and remarkably suppressed the mammosphere formation compared to that in single MDA-MB-231 cells (p<0.05). HMGB3-siRNA remarkably reduced Nanog, SOX2, and OCT-4 and significantly enhanced CD44+/CD24- cells compared to single MDA-MB-231 cells (p<0.05). HMGB3-siRNA significantly weakened the expression of HIF1α in MDA-MB-231 cells compared to single MDA-MB-231 cells (p<0.05). HMGB3 was positively correlated with HIF1α expression (p<0.05). There was an interaction between HMGB expression and HIF1α expression. CONCLUSIONS HMGB3 small interfering RNA suppressed the formation of mammosphere in MDA-MB-231 cells by downregulating the expression of HIF1α.

Abstract
OBJECTIVE To investigate whether miR-374b can promote the differentiation of MSCs into osteoblasts by mediating PTEN, thus promoting fracture healing. MATERIALS AND METHODS Primary cultured mouse mesenchymal stem cells were obtained for following experiments. Flow cytometry was used to determine the expression of MSCs surface antigens to identify the purity. Alizarin red staining was used to detect whether MSCs could differentiate into osteoblasts. QRT-PCR was used to detect the expression of osteogenic marker genes as well as miR-374b and PTEN in bone marrow-derived MSCs from fractured mice model. ALP activity detection kit was used to detect ALP activity in cells. Changes of osteogenic proteins in cells were evaluated by Western blot. Bioinformatics methods were used to predict the binding sites between miR-374 and target genes. Luciferase reporter assay was used to confirm whether miR-374 could bind to the target gene. RESULTS Under normal culture, MSCs grew into a long fusiform shape on the 4th day. After induced in the osteogenic induction medium for seven days, calcified nodules appeared. The results of the detection of MSCs surface antigen markers showed that CD90 was 99.12%, and CD45 was 0.23%. Alizarin red staining showed that MSCs possess the ability to differentiate into osteogenic. The expression level of MiR-374b and PTEN increased significantly in the early stage of fracture in mice, but no significant difference was observed at a later stage. After overexpression of miR-374b, the cell ALP activity, the expression of osteogenesis-related genes and osteogenesis-related proteins was significantly increased, while after knocking out miR-374b, the opposite result was observed. The result of luciferase reporting assay showed that miR-374b can bind to PTEN. As mentioned above, overexpression of miR-374b resulted in upregulation of osteogenic-related genes and proteins, while over-expression of both PTEN and miR-374b could partly reverse the outcomes. CONCLUSIONS miR-374b can promote osteogenic differentiation of MSCs by degrading PTEN, thereby promoting fracture healing.

Abstract
OBJECTIVE Grape seed proanthocyanidin extract (GSPE), as one of the most popular natural drug extracted from the grape, has been reported to improve endothelial function and arteriosclerosis. However, little is known about the influence of GSPE on hypertension and vascular remodeling. Profilin-1, an Actin-binding protein, is closely involved in the remodeling of large vessels in ouabain-induced hypertension. To date, there is no effective prevention or treatment in place for the high incidence of ischemic stroke associated with hypertension. In this study, we aimed to determine the role of GSPE via inhibition Profilin-1 in ischemic cerebral cortices of ouabain-hypertension rats and potentially provide a new target to prevent stroke associated with hypertension. MATERIALS AND METHODS The blood pressure of male Sprague-Dawley (SD) rats was measured during a period of ouabain-induced hypertension. The expression of Profilin-1, vascular endothelial growth factor (VEGF) and endothelial nitric oxide synthase (eNOS) in the cerebral cortex were determined by quantitative Real Time-PCR (qRT-PCR) and Western blot. Histopathological and behavioral tests were also conducted. RESULTS Blood pressure elevation started at week 5 and reached clinical standards for hypertension at week 8. GSPE was proved to suppress Profilin-1 and VEGF levels through inhibition of Profilin-1-protein kinase B (AKT)-hypoxia inducible factor-1α (HIF-1α) signal pathway and promote eNOS expression. Moreover, the histopathological and ethiological improvement was observed in GSPE over-expression and Profilin-1 inhibition groups. CONCLUSIONS We detected that GSPE could improve cerebral vascular damage through inhibiting Profilin-1 in an ouabain-induced hypertension model.

Abstract
Surgical margin principle is one of the central surgical principles for head and neck cancers. Negative surgical margin is the primary purpose of surgery for head and neck cancers. This paper is based on the current clinical application of surgical margins of head and neck cancers, and it is proposed that surgical margins of head and neck cancers may be classified into three types: surface margin, deep margin, and tissue interface margin in consideration of surgical exposure of tumors. The classification of surgical margins can make the clinical application and the research of surgical margins of head and neck cancers more systematic and clear.

Abstract
Objective: To evaluate the prevalence and risk factors of aortic valve calcification among the elderly (≥65 years old) resident of Wuxi city, Jiangsu province. Methods: The household registration population aged ≥65 years old in Wuxi city was selected as the research subject by stratified sampling method from August 2017 to December 2018. Echocardiography was performed to assess the aortic valve calcification, and the participants were divided into calcification group and non-calcification group. Multivariate logistic regression analysis was used to explore the related risk factors of aortic valve calcification. Results: The age of the respondents was (73.6±7.1) years old, of which 48.8% (461 cases) were males.The prevalence rate of aortic valve calcification was 22.0% (208/944) in the elderly (≥ 65 years old) residents in Wuxi city. The prevalence rate in 65-69 years old, 70-74 years old, 75-79 years old, 80-84 years old and ≥85 years old was 16.7% (58/347),16.7% (41/245),16.2% (26/161),23.3% (24/103), and 67.0% (59/88),respectively. There were significant differences in age, weight, abdominal circumference, hip circumference, high-salt diets, exercise, hypertension, hyperlipidemia, diabetes, coronary heart disease, cerebrovascular disease, and carotid atherosclerosis between the non-calcified group (736 cases) and the calcified group (208 cases) (P<0.01 or 0.05).Multivariate logistic regression analysis showed that age (OR=1.077, 95%CI 1.053-1.101, P<0.001), diabetes mellitus (OR=1.697, 95%CI 1.174-2.453, P=0.005), and coronary heart disease (OR=1.964, 95%CI 1.378-2.799, P<0.001) were the risk factors of aortic valve calcification. Conclusions: The prevalence of aortic valve calcification in the elderly (≥65 years old) residents in Wuxi city of Jiangsu province increases with aging. Age, diabetes mellitus and coronary heart disease are the risk factors of aortic valve calcification in this population cohort.

Abstract
Most of the common dizziness/vertigo diseases in otology clinic are peripheral vertigo diseases, and while about 20% -30% of all vertigo diseases are caused by central nervous system diseases. Pseudo vestibular neuritis, acute ischemic stroke with audiovestibular loss, and central paroxysmal positional vertigo are the three types of central "malignant vertigo" diseases which are most easily misdiagnosed by otologists. This article described the clinical characteristics and bedside physical performance of these three diseases, and summarized the differential diagnosis points for clinical reference.

Abstract
Objective:To investigate the clinical features of LC-BPPV with direction-fixed horizontal nystagmus in the primary Roll test. Method:Nine patients of LC-BPPV with bilateral direction-fixed horizontal nystagmus in the first Roll test were treated by repositioning maneuvers after judging the affected side and the prognosis was observed. Result:The affected side of eight patients was the side of the apogeotropic nystagmus. Barbecue or Gufoni maneuvers was effective for reposition. The other one had no conversion of nystagmus and could not judge the affected side. Conclusion:The nystagmus performance of patients with LC-BPPV is complicated. It is necessary to carefully analyze the nystagmus performance of each position. Combining with bow and lean test, lying down test and null plane, the position of the otolith is inferred. Comprehensive use of the Barbecue or Gufoni maneuvers, forced side lying on the affected side, mastoid sniper, shaking head method is effective to complete the reposition treatment.

Abstract
Epigenetic mutations caused by pollutants are possibly linked to many diseases. Benzo(a)pyrene (BaP) is one of the most representative air pollutants and has aroused wide concern because of its strong carcinogenicity. The reproductive toxicity induced by BaP has been identified, but little is known about the characteristics of the methylation changes induced by BaP. In this study, a methylated DNA immunoprecipitation sequencing method was used to detect the methylation of sperm DNA of rats exposed to BaP. Compared with the respective genes in normal rats, there were 3227 hypomethylated genes and 828 hypermethylated genes after BaP exposure. Gene ontology enrichment analysis reported that differentially methylated genes (DMGs) were enriched in the localization, single-multicellular organism process and plasma membrane. Kyoto Encyclopedia of Genes and Genomes pathway analysis showed that the DMGs were significantly enriched in the Ras signalling pathway, Rap1 signalling pathway, pancreatic secretion and neuroactive ligand-receptor interaction. DisGeNET disease spectrum analysis showed that DMGs were associated with infertility and certain genetic diseases. Further research needs to be done to explore whether these abnormal methylation are transgenerational.

Abstract
Objective: To survey the conduction and evaluate the effectiveness of extracorporeal membrane oxygenation (ECMO) therapy in pediatric intensive care unit (PICU) in China mainland. Methods: In a questionnaire-based survey, we retrospectively reviewed the application of ECMO in children's hospital and general hospital in China mainland to summarize and analyze the categories of diseases and prognosis of children treated with ECMO therapy. Results: By December 31, 2017, a total of 23 hospitals using ECMO, including 22 tertiary referral hospitals and 1 secondary hospital, among which 16 were children's hospitals and 7 were general hospitals. Thirty-seven ECMO equipment was available. A total of 518 patients treated with ECMO, within whom 323 (62.4%) successfully weaned from ECMO and 262 (50.6%) survived to discharge. Among 375 pediatric patients, 233 (62.1%) were successfully weaned from ECMO and 186 (49.6%) survived to discharge. Among 143 newborn patients, 90 (62.9%) successfully weaned from ECMO, 76 (53.1%) survived to discharge. ECMO was applied in veno-arterial (VA) mode to 501 (96.7%) patients, veno-venous (VV) mode to 14 (2.7%) patients, and VV-VA conversion mode to 3 (0.6%) patients. Sixty-nine patients required extracorporeal cardiopulmonary resuscitation (ECPR), including 20 newborn patients (29.0%) and 38 pediatric patients (71.0%), who were all with cardiovascular disease. Neonatal respiratory distress syndrome (26/61), persistent pulmonary hypertension of the newborn (PPHN) (12/61), and meconium aspiration syndrome (MAS) (11/61) are the most common pulmonary diseases in newborn patients; among whom, infants with PPHN had highest survival rate (10/12), followed by MAS (9/11). Among newborn patients with cardiovascular diseases, those who admitted were after surgery for congenital cardiac disease were the most common (54/82), while those with septic shock had the highest survival rate (2/3). In pediatric pulmonary diseases, acute respiratory distress syndrome was the most common (42/93), while plastic bronchitis was with the highest survival rate (4/4), followed by viral pneumonia (13/16). Among pediatric cardiovascular diseases, congenital cardiac defect was the most common (124/282), while fulminant myocarditis had the highest survival rate (54/77). Conclusion: The application of ECMO as a rescue therapy for children with severe cardiopulmonary failure has dramatically developed in China mainland.

Result:The expression of LINC00460 was significantly upregulated in the LSCC tissue compared with that of adjacent normal mucosal tissue (P=0.006). There were no statistical differences of the quantity of LINC00460 expression among supraglottic, glottic and subglottic LSCC (P>0.05). Moreover, LINC00460 had no significant changes in poorly differentiated LSCC when compared with that of well and moderately differentiated LSCC (P>0.05). Furthermore, the expression of LINC00460 in LSCC with lymph node metastasis had no significant changes when compared with that without of lymph node metastasis (P>0.05). Notably, LINC00460 expression in T1+T2 stages patients were significantly lower than T3+T4 stages (P<0.05). Conclusiont:Upregulation of long non-coding RNA LINC00460 might contribute to the carcinogenesis and development of LSCC, furthermore play important biological function.

Abstract
We previously reported that dental stem cell-mediated bioengineered tooth root (bio-root) regeneration could restore tooth loss in a miniature pig model. As a potential new method for tooth restoration, it is essential to compare this method with the widely used commercial dental implant-based method of tooth restoration. Tooth loss models were created by extracting mandibular incisors from miniature pigs. Allogeneic periodontal ligament stem cells (PDLSCs) and dental pulp stem cells (DPSCs) were isolated and cultured. A PDLSC sheet was prepared by adding 20.0 µg/mL vitamin C to the culture medium; in addition, a hydroxyapatite tricalcium phosphate (HA/TCP)/DPSC graft was fabricated and cultured in a 3-dimensional culture system. A total of 46 bio-root implantations and 9 dental implants were inserted, and crown restorations were performed 6 mo after implantation. Histological, radiological, biomechanical, and elemental analyses were used to evaluate and compare tissue-engineered bio-roots and dental implants to the natural tooth roots. After 6 mo, both computed tomography scans and histological examinations showed that root-like structures and dentin-like tissues had formed. Three months after crown restoration, clinical assessments revealed that tooth function was equivalent in the regenerated bio-root and the dental implant. Biomechanical testing showed that the bio-roots were similar to natural tooth roots in compressive strength, modulus of elasticity, and torsional force; however, these properties were significantly higher in the dental implants. Elemental analysis revealed a higher similarity in elemental composition between bio-roots and natural tooth roots than between bio-roots and dental implants. However, the dental implant success rate was 100% (9 of 9) and the bio-root success rate was only 22% (10 of 46). Taken together, we showed that an allogeneic HA/TCP/DPSC/PDLSC sheet could successfully build a bio-root with structure and function similar to the natural tooth root; however, tissue engineering procedures must be optimized further to improve the success rate.

Abstract
As a member of the POU-domain family, the POU1F1 is a positive regulator for growth hormone, prolactin and thyroid-stimulating hormone b, by binding to target DNA promoters as a dimer in mammals. This study described the polymorphisms at the goat POU1F1-DdeI locus and analyzed the distribution of alleles in 15 indigenous Chinese goat breeds. The PCR-RFLP analysis showed a predominance of the D1D1 genotype and the D1 allele, with average frequencies of 0.550 and 0.790, respectively, irrespective of goat utility type. The D1D2 genotype was the second most frequent, with a mean frequency of 0.371. The distributions of genotypic and allelic frequencies at this locus were found to be significantly different among populations based on a Chi square test (P < 0.001), suggesting that the breed factor significantly affected the molecular genetic character of the POU1F1 gene. The genetic diversity analysis revealed that Chinese indigenous populations had a wide spectrum of genetic diversity at the goat POU1F1-DdeI locus. However, an ANOVA analysis revealed no significant differences in gene homozygosity, gene heterozygosity, effective allele numbers, or polymorphism information content among meat, dairy, and cashmere utility types (P > 0.05). This suggests that the goat utility types had no significant effect on the spectrum of genetic diversity.

Abstract
The classic renin-angiotensin system (RAS) is a complex system in which angiotensin II (Ang II) has been identified as an important endogenous regulator that influences both smooth muscle contraction and cell growth. Although a local RAS is known to exist in the gastrointestinal tract, it is unclear whether Ang II is involved in the loss of gastric interstitial cells of Cajal (ICC) in diabetic mice. The present study was designed to investigate the effect of Ang II on ICC survival in streptozotocin (STZ)-induced diabetic mice. Western blot, immunofluorescence, isometric muscle recording, enzyme-linked immunosorbent assay (ELISA) and a cell counting kit-8 were used in this research. Our results demonstrate that the c-Kit and membrane-bound stem cell factor (mSCF) protein expression levels in gastric smooth muscle were decreased in STZ-induced diabetic mice. However, the angiotensin receptor type 1 (AT1R) expression levels in gastric smooth muscle and angiotensin-converting enzyme (ACE) expression levels in gastric mucosa were increased. The effect of Ang II on the tonic contraction of gastric smooth muscle was potentiated in diabetic mice, and the plasma Ang II level was enhanced. Ang II increased mSCF expression, cell proliferation, and Akt-Ser473 phosphorylation in cultured gastric smooth muscle cells (GSMCs). These effects were reduced by specific inhibitors ZD7155 (an AT1R antagonist) and LY294002 (a PI3-kinase inhibitor). Our results suggest that Ang II increases mSCF expression and cell proliferation in cultured GSMCs in a PI3K/Akt signaling-dependent manner. ACE and AT1R up-regulation in the stomach may help compensate for ICC loss in STZ-induced diabetic mice.

Abstract
This study was conducted to evaluate the relative bioavailability (RBV) of 25-hydroxycholecalciferol (25-OH-D3) to cholecalciferol (vitamin D3) in 1- to 21-d-old broiler chickens fed with calcium (Ca)- and phosphorus (P)-deficient diets. On the day of hatch, 450 female Ross 308 broiler chickens were assigned to nine treatments, with five replicates of ten birds each. The basal diet contained 0.50% Ca and 0.25% non-phytate phosphorus (NPP) and was not supplemented with vitamin D. Vitamin D3 was fed at 0, 2.5, 5.0, 10.0, and 20.0 μg/kg, and 25-OH-D3 was fed at 1.25, 2.5, 5.0, and 10.0 μg/kg. The RBV of 25-OH-D3 was determined using vitamin D3 as the standard source by the slope ratio method. Vitamin D3 and 25-OH-D3 intake was used as the independent variable for regression analysis. The linear relationships between the level of vitamin D3 or 25-OH-D3 and body weight gain (BWG) and the weight, length, ash weight, and the percentage of ash, Ca, and P in femur, tibia, and metatarsus of broiler chickens were observed. Using BWG as the criterion, the RBV value of 25-OH-D3 to vitamin D3 was 1.85. Using the mineralization of the femur, tibia, and metatarsus as criteria, the RBV of 25-OH-D3 to vitamin D3 ranged from 1.82 to 2.45, 1.86 to 2.52, and 1.65 to 2.05, respectively. These data indicate that 25-OH-D3 is approximately 2.03 times as active as vitamin D3 in promoting growth performance and bone mineralization in broiler chicken diets.

Abstract
OBJECTIVE To investigate the plasma osteoprotegerin level and osteoprotegerin expression in renal biopsy tissue in type 2 diabetes with nephropathy. METHODS Plasma osteoprotegerin level was measured by enzyme-linked immunoassay in 48 type 2 diabetes with normoalbuminuria, 48 patients with microalbuminuria, 44 patients with macroalbuminuria and 40 healthy persons. Part of diabetes patients with nephropathy were performed kidney biopsy by ultrasound guide. The osteoprotegerin expression in kidney biopsy tissue is examined by immunohistochemistry. RESULTS The plasma osteoprotegerin levels were significantly elevated in patients with microalbuminuria (3.73±0.75 ng/l) and macroalbuminuria (4.68±0.82 ng/l) as compared with patients with normoalbuminuria (2.71±0.69 ng/l) and control subjects (2.11±0.42 ng/l). And the plasma osteoprotegerin level in macroalbuminuric group was also higher than that in microalbuminuria group. The plasma osteoprotegerin level had a positive correlation with the fasting plasma glucose (FPG), 2-h plasma glucose (2hPG), glycohemoglobinA1c (HbA1C), high sensitive C-reactive protein (hsCRP) and log(UAER). Multivariate regression analysis revealed that plasma osteoprotegerin level was an independent factor associated with albuminuria in type 2 diabetes. The immunohistochemistry results showed that positive immunostaining for osteoprotegerin was observed in the renal tubule cells of biopsy and not in glomerulus, and the osteoprotegerin expression was higher in macroalbuminuria group than that in microalbuminuria group. CONCLUSIONS The plasma osteoprotegerin level and the osteoprotegerin expression in renal tubule cells of biopsy tissue were increased in nephropathy of type 2 diabetes. This finding supports the growing concept that osteoprotegerin may act as an important regulatory molecule in the angiopathy, and particularly, that it may be involved in the occurrence and development of nephropathy in type 2 diabetes.

Abstract
BACKGROUND Hydrogen sulfide (H2 S) has been shown to have an excitatory effect on gastric motility, but the underlying molecular mechanism is unclear. In this study, we aimed to investigate the possible targets of H2 S and determine how H2 S affects its target proteins during H2 S-induced contraction. METHODS Patch-clamp and potentiometric fluorescence dye were utilized to measure the electrophysiological changes. The Biotin-switch assay was utilized to detect the protein S-sulfhydration. The isometric tension measurement was conducted too. KEY RESULTS Exogenous H2 S enhanced the tonic contraction of gastric antral smooth muscle, and voltage-dependent potassium channel (KV ) blocker and Dithiothreitol (DTT, a reducing agent) abolished the excitatory effect of NaHS. Exogenous H2 S inhibited the fast inactivation component of the voltage-dependent potassium channel current (IKVfast ) in isolated gastric antral smooth muscle cells. H2 S inhibited the KV 4.3 current in H293 cells with heterologous expression of KV 4.3, but did not inhibit the KV 4.1 and KV 4.2 currents, which together contribute greatly to IKVfast . NaHS significantly decreased the membrane potential in cultured gastric smooth muscle cells, but the NaHS-induced depolarization was suppressed by knockdown of KV 4.3 and N-ethylamaleimide (NEM), a free thiol group blocker. In addition, NaHS sulfhydrated KV 4.3 in H293 cells and in gastric smooth muscle tissue. However, this S-sulfhydration was inhibited by NEM and DTT. Meanwhile the NaHS-induced inhibition of IKVfast and KV 4.3 was also blocked by NEM and DTT. CONCLUSIONS & INFERENCES These results suggest that exogenous H2 S sulfhydrates KV 4.3 to decrease the membrane potential, thereby enhancing the basal tension of gastric antral smooth muscle.

Abstract
Agastache rugosa (family Lamiaceae) is one of the most common herbs of traditional Chinese medicine in China, and the species increasingly gains popularity on the international market. In June 2012, typical mosaic symptoms were observed on many A. rugosa plants in a field in Shanxi Province. The incidence of this disease reached more than 60% in a 2.6-ha field. Seven symptomatic plants were tested by DAS-ELISA using monoclonal antibodies specific for Tobacco mosaic virus (TMV), Cucumber mosaic virus (CMV), and Tomato mosaic virus (ToMV); all antisera used in DAS-ELISA were generated and validated in our laboratory. CMV was found in all seven samples tested, but not TMV and ToMV. Double-stranded RNAs (dsRNA) extracted from infected leaves were used as templates in the subsequent two-step RT-PCR reaction (1). In order to further confirm the presence of CMV, a pair of specific primers (forward: 5'-ACGTCGACCATGGACAAATC-3', and reverse: 5'-TACCCGGGTCAGACTGGTAGCACC-3') based on the coat protein gene sequence of CMV were used to amplify PCR products of the expected size (657 bp) from ELISA-positive samples (2). These PCR products were cloned into pUCm-T Vector (Sangon Biotech, Shanghai) and sequenced. Five independent clones have been sequenced to obtain the consensus sequence. This consensus sequence (GenBank Accession No. JQ403529) was compared with other CMV sequences available in GenBank using DNAMAN. The partial CMV coat protein sequence showed the highest 97.9% nucleotide identity with a subgroup IB CMV isolate from China (DQ459481). To our knowledge, this is the first report of the natural occurrence of CMV on A. rugosa. References: (1) M. Krajacić et al. J. Chromatogr. A. 1144:111, 2007. (2) F. Li et al. J.

Abstract
Two experiments were conducted to determine the effects of different dietary lysine levels on the apparent nutrient digestibility, the serum amino acid (AA) concentration, and the biochemical parameters of the precaval and portal vein blood in growing pigs. In Experiment 1, 15 noncannulated pigs received diets with different lysine densities (0.65%, 0.95%, and 1.25% lysine) for 13 d. A total collection digestion test was performed, and blood samples were collected from the precaval vein at the end of the experiment. In Experiment 2, four cannulated pigs were fed the same diets of Experiment 1. The experiment used a self-control experimental design and was divided into three periods. On d 5 of each period, at 0.5 h before feeding and hourly up to 8 h after feeding, single blood samples were collected from catheters placed in the portal vein. In Experiment 1, some serum AAs (including lysine), serum urinary nitrogen (SUN), and total protein (TP) concentrations were significantly affected by the dietary lysine levels (p<0.05). Moreover, the 0.65% lysine treatment showed a significant lower apparent digestibility of gross energy, dry matter, crude protein, and phosphorus than the other treatments (p<0.05). In Experiment 2, serum lysine, histidine, phenylalanine, threonine, valine, isoleucine (p = 0.0588), triglyceride, and SUN (p = 0.0572) concentrations were significantly affected by the dietary lysine levels (p<0.05). Additionally, almost all of the determined serum AA and total AA concentrations reached their lowest values at 0.5 h before feeding and their highest values at 2 h after feeding (p<0.05). These findings indicate that the greatest absorption of AA occurred at 2 h after feeding and that the dynamic profile of serum AA is affected by the dietary lysine levels. Moreover, when the dietary lysine content was 0.95%, the growing pigs achieved a better nutrient digestibility and serum metabolites levels.

Abstract
Methionine aminopeptidases (MetAPs), which remove methionine residue from newly synthesized polypeptide chains, are a class of metalloproteases ubiquitously distributed in both eukaryotes and prokaryotes. MetAP-2 inhibition can induce G1 cell cycle arrest, cytostasis in tumor cells in vitro and inhibition of tumor growth in vivo. The discovery of fumagillin with potent antiangiogenic and antiproliferative activities promoted the development of fumagillin analogues as a novel class of anticancer agents. Early drug discovery efforts have focused on analogs of fumagillin, which irreversibly inhibit MetAP-2 through covalent modification of an epoxide. Several fumagillin analogs, like CKD-732, TNP-470 and PPI-2458, were found to be potent selective inhibitors of MetAP-2 (proteolytic activity) and endothelial cell proliferation. Further, they have entered in clinical trials for the treatment of different types of tumors. Recently, attention has been paid to reversible human MetAP-2 inhibitors, such as bengamides, 2-hydroxy-3-aminoamides, anthranilic acid sulfonamides and triazole analogs, which have demonstrated their potential to inhibit angiogenesis and tumor growth in vivo as well. This review article mainly discussed the development of MetAP-2 inhibitors in cancer therapy and also summarized their structure-activity relationships.

Abstract
Reparative dentin formation is essential for maintaining the integrity of dentin structure during disease or trauma. In this study, we investigated stem/progenitor cell-based tissue engineering for dentin regeneration in a large animal model. Porcine deciduous pulp stem/progenitor cells (PDPSCs) were mixed with a beta-tricalcium phosphate (β-TCP) scaffold for dentin regeneration. Different concentrations of PDPSCs were tested to determine the optimal density for dentin regeneration. Aliquots of 5×10(5) PDPSCs in 1 mL resulted in the highest number of cells attached to the scaffold and the greatest alkaline phosphatase activity. We labeled PDPSCs with green fluorescent protein (GFP) and used the optimal cell numbers mixed with β-TCP to repair pulp chamber roof defects in the premolars of swine. Four weeks after transplantation, GFP-positive PDPSCs were observed in PDPSC-embedded scaffold constructs. At 16 weeks after transplantation, the PDPSCs mixed with β-TCP significantly regenerated the dentin-like structures and nearly completely restored the pulp chamber roof defects. This study demonstrated that the PDPSC/scaffold construct was useful in direct pulp-capping and provides pre-clinical evidence for stem/progenitor cell-based dentin regeneration.

Abstract
The origins of the domestic water buffalo remain contentious. To better understand the origins of Chinese water buffalo, we sequenced the complete mitochondrial cytochrome b (MT-CYB) gene from 270 individuals representing 13 Chinese domestic swamp buffalo populations. We found genetic evidence of introgression of river buffalo into Chinese swamp buffalo herds. Swamp buffalo haplotypes can be divided into two highly divergent lineages (A and B), suggesting that Chinese native swamp buffalo have two maternal origins. We found that the A→G transition in the buffalo MT-CYB gene stop codon resulted in buffalo haplotypes being terminated by one of two stop codons: AGA or AGG. AGA is common to river buffalo and lineage A of swamp buffalo, while AGG is specific to lineage B of swamp buffalo. Lineage A appears to have been domesticated in China. Further genetic evidence is required to clarify the origins of lineage B.

Abstract
INTRODUCTION Defects in insulin-stimulated glucose uptake in muscle are the important early events in the pathogenesis of insulin resistance. NYGGF4 (also named PID1) is a recently discovered gene which is suggested to be associated with obesity-associated insulin resistance. In this study, we aimed to investigate the effects of NYGGF4 on glucose uptake and insulin signaling in rat skeletal muscle cells. METHODS Rat L6 myoblasts were transfected with either an empty vector or an NYGGF4-expressing vector and induced to differentiate into mature L6 skeletal myotubes. Glucose uptake was determined by measuring uptake of 2-deoxy-d-[(3)H] glucose. Immunoblotting was performed to detect the translocation of insulin-sensitive glucose transporter 4 (GLUT4). Immunoblotting was also used to measure phosphorylation and total protein levels of the insulin signaling proteins including insulin receptor (IR), insulin receptor substrate 1 (IRS1), Akt, extracellular signal-regulated kinase 1 and 2 (ERK1/2), p38, and c-Jun-N-terminal kinase (JNK). RESULTS NYGGF4 over-expression in L6 skeletal myotubes reduced insulin-stimulated glucose uptake and impaired insulin-stimulated GLUT4 translocation. It also diminished insulin-stimulated tyrosine phosphorylation of IRS1 and serine phosphorylation of Akt without affecting the phosphorylation of IR, ERK1/2, p38, or JNK. CONCLUSIONS Over-expression of NYGGF4 inhibits glucose transport in skeletal myotubes by blocking the IRS1/PI3K/AKT insulin pathway. These observations highlight the potential role of NYGGF4 in glucose homeostasis and the development of insulin resistance in obesity.

Abstract
This prospective randomized study compared the clinical and radiological results of primary total knee arthropasty (TKA) using a mini-subvastus approach (group I; n = 35) or a standard approach (group II; n = 33). A posterior-stabilized prosthesis was used in both groups by the same surgeon. Mean follow-up was 18 months (range 14 - 26 months). Patients in group I lost less blood and experienced less pain 1 day post-operatively. They achieved an active straight leg raise earlier and underwent less lateral retinacular releases. Functional outcome and the range of knee movements were significantly better in group I up to 9 months post-operatively, but there was no significant difference between the groups at 1 year post-operatively or at final follow-up. Reduced access and visibility in group I prolonged the operation time and resulted in five technical errors on radiographic evaluation. Based on these results, the authors currently only use the mini-subvastus approach for minimally invasive TKA in selected cases.

Abstract
A rapid quantitative polymerase chain reaction (QPCR) method was developed for simultaneous detection of enteric bacteria from surface waters by utilizing a pair of universal primers which targeted four bacteria strains, namely Shigella dysenteriae, Vibrio cholerae, Salmonella typhimurium, and Escherichia coli. It was estimated that the QPCR method had a 94% confidence, and a detection limit as 2.7 E. coli cells per sample in undiluted DNA extracts. The QPCR method was applied for the bacteriological examination of several surface waters in the urban area of Xi'an, China and comparison was made with the conventional bacteria indicators determined by conventional membrane filter (MF) method. As a result, the calibrator cell equivalents (CCE) determined by QPCR was 2.2 to five times of the total coliform CFU, and the characteristics of the bacterial quality of different waters could be well presented by the QPCR results with a higher sensitivity. The coefficient of variation (CV) of data obtained by QPCR was smaller than that by traditional MF method, indicating a more stable analysis result. The QPCR method could thus be used as a supplement of the conventional culture method for more sensitive detection of pathogenic enteric bacteria from water.

Abstract
Stem cells from human exfoliated deciduous teeth have been identified as a new post-natal stem cell population with multipotential differentiation capabilities, including regeneration of mineralized tissues in vivo. To examine the efficacy of utilizing these stem cells in regenerating orofacial bone defects, we isolated stem cells from miniature pig deciduous teeth and engrafted the critical-size bone defects generated in swine mandible models. Our results indicated that stem cells from miniature pig deciduous teeth, an autologous and easily accessible stem cell source, were able to engraft and regenerate bone to repair critical-size mandibular defects at 6 months post-surgical reconstruction. This pre-clinical study in a large-animal model, specifically swine, allows for testing of a stem cells/scaffold construct in the restoration of orofacial skeletal defects and provides rapid translation of stem-cell-based therapy in orofacial reconstruction in human clinical trials.

Abstract
In order to gain knowledge on the presence of bacteria and viruses in urban waters, the authors started a long-term study on the microbiological quality of urban lakes and rivers in Xi'an, China. In the current study, enteroviruses were chosen as typical viruses and RT-nested PCR was conducted for their detection. Universal primers were designed for simultaneous detection of poliovirus, coxsackievirus, and enterovirus 71 which are the most frequently encountered enteroviruses in China. The RT-nested PCR protocol established in this study showed high sensitivity and specificity. The detection limit was equivalent to 0.038 CCID50 per litre by applying a modified adsorption-elution concentration method. No cross-reactivity was observed using the genome of pathogenic bacteria as of PCR template. The occurrence of enteroviruses was compared with fecal coliform count in a 6-month period from July to December 2006 for the urban waters. As a result, it was noticed that the presence of enteroviruses might not relate to the fecal coliform count so much. Statistical analysis also indicated that there was no significant correlation between the presence of enteroviruses and that of total bacteria, total coliform, and fecal coliform.

Abstract
Functional magnetic resonance imaging (fMRI) is emerging as a powerful tool for studying the process underlying the working of the many regions of the human brain. The standard tool for analyzing fMRI data is some variant of the linear model, which is restrictive in modeling assumptions. In this paper, we develop a semiparametric approach, based on the cubic smoothing splines, to obtain statistically more efficient estimates of the underlying hemodynamic response function (HRF) associated with fMRI experiments. The hypothesis testing of HRF is conducted to identify the brain regions which are activated when a subject performs a particular task. Furthermore, we compare one-level and two-level semiparametric estimates of HRF in significance tests for detecting the activated brain regions. Our simulation studies demonstrate that the one-level estimates combined with a bias-correction procedure perform best in detecting the activated brain regions. We illustrate this method using a real fMRI data set and compare it with popular methods offered by AFNI and FSL.

Abstract
OBJECTIVE To compare the effect of several types of rib rings with intercostal muscles for the replacement of trachea in thorax. METHODS The surface layer of the third rib of dogs were ripped off and curved into triangular, quadrilateral and polygonal form. These three types of rib rings with intercostal muscles were used to replace a segment of trachea in thorax. RESULTS The stability of triangular rib ring was very well, but stricture of ring were often happened because of its smaller internal diameter. These stability of quadrilateral rib ring was the worst. The polygonal rib ring presented the biggest diameter and good stability compared to the other two kinds of rings. If silicone tube was supplemented in the polygonal rib ring, the quality of artificial trachea was excellent. CONCLUSION The rib rings with intercostal muscles are successfully used for replacing the defect of trachea in canine thorax. The polygonal rib rings have the best quality in the three types of rib ring for tracheal replacement.

Abstract
This work demonstrates that proper selection of a metal ion and chelating ligand enables recovery of a his(6)-tagged protein from canola (Brassica napus) extracts by immobilized metal affinity chromatography (IMAC). When using Co(2+) with iminodiacetate (IDA) as the chelating ligand, beta-glucuronidase-his(6) (GUSH6) can be purified from canola protein extract with almost homogeneous purity in a single chromatographic step. The discrimination with which metal ions bound native canola proteins followed the order Cu(2+) < Ni(2+) < Zn(2+) < Co(2+) in regard to elimination of proteins coeluted with the fusion protein. IDA- and nitrilotriacetate (NTA)-immobilized metal ions showed different binding patterns, whose cause is attributed to a more rigid binding orientation of the his(6) in forming a tridentate with Me(2+)-IDA than in forming a bidentate with Me(2+)-NTA. The more flexible binding allows for multisite interactions over the protein.

Abstract
In order to investigate the relationship between the retrograde changes of the skeletal muscle and the time of death in various postmortem intervals (PMI), a systemic study of the enzymehistochemical activity of AChE, SDH, LDH, Ca(2+)-ATPase and the immunohistochemical reaction of SYN in motor end-plates and muscle fibers was conducted in rats under different temperatures and at various PMI. The results were analyzed and compared by an image processing system. It was found that these changes were related to the PMI, especially AChE changes. The AChE could be used as a sign-enzyme of skeletal muscle to date death.
