Abstract
To report two novel TTN variants associated with fetal recessive titinopathy, thereby broadening the range of TTN variants that can lead to titinopathy. Clinical information on the fetus and parents was gathered, and genomic DNAs were extracted from the fetal tissue and family members' peripheral blood samples. Exome sequencing on fetal DNA was performed and following bioinformatics analysis, the suspected pathogenic variants were confirmed through Sanger sequencing. Prenatal ultrasound performed at 29 weeks of gestation revealed hydrops fetalis, decreased fetal movements, multiple joint contractures and polyhydramnios. Intrauterine fetal death was noted in the third trimester. Exome sequencing revealed compound heterozygous variants in the TTN gene: a paternally inherited allele c.101227C>T (p.Arg33743Ter) and a maternally inherited c.104254C>T (p.Gln34752Ter) allele. These variants have not been previously reported and are evaluated to be likely pathogenic according to the American College of Medical Genetics and Genomics guidelines. We report a fetus with hydrops fetalis and arthrogryposis multiplex congenita associated with a compound heterozygote in the TTN gene. Our report broadens the clinical and genetic spectrum associated with the TTN-related conditions.

Abstract
The present study aimed to investigate the acute effects and the mechanism of ketamine on nicotine-induced relaxation of the corpus cavernosum (CC) in mice. This study measured the intra-cavernosal pressure (ICP) of male C57BL/6 mice and the CC muscle activities using an organ bath wire myograph. Various drugs were used to investigate the mechanism of ketamine on nicotine-induced relaxation. Direct ketamine injection into the major pelvic ganglion (MPG) inhibited MPG-induced increases in ICP. D-serine/L-glutamate-induced relaxation of the CC was inhibited by MK-801 (N-methyl-D-aspartate (NMDA) receptor inhibitor), and nicotine-induced relaxation was enhanced by D-serine/L-glutamate. NMDA had no effect on CC relaxation. Nicotine-induced relaxation of the CC was suppressed by mecamylamine (a non-selective nicotinic acetylcholine receptor antagonist), lidocaine, guanethidine (an adrenergic neuronal blocker), Nw-nitro-L-arginine (a non-selective nitric oxide synthase inhibitor), MK-801, and ketamine. This relaxation was almost completely inhibited in CC strips pretreated with 6-hydroxydopamine (a neurotoxic synthetic organic compound). Ketamine inhibited cavernosal nerve neurotransmission via direct action on the ganglion and impaired nicotine-induced CC relaxation. The relaxation of the CC was dependent on the interaction of the sympathetic and parasympathetic nerves, which may be mediated by the NMDA receptor.

Abstract
Arrhythmia is an external manifestation of cardiac electrophysiological disorder. It exists in healthy people and patients with various heart diseases, which is often associated with other cardiovascular diseases. The contraction and diastole of myocardium are inseparable from the movement of ions. There are many ion channels in the membrane and organelle membrane of myocardium. The dynamic balance of myocardial ions is vital in maintaining myocardial electrical homeostasis. Potassium ion channels that have a complex variety and a wide distribution are involved in the whole process of resting potential and action potential of cardiomyocytes. Potassium ion channels play a vital role in maintaining normal electrophysiological activity of myocardium and is one of the pathogenesis of arrhythmia. Traditional Chinese medicine(TCM)has unique advantages in treating arrhythmia for its complex active components and diverse targets. A large number of TCM preparations have definite effect on treating arrhythmia-related diseases, whose antiarrhythmic mechanism may be related to the effect on potassium channel. This article mainly reviewed the relevant studies on the active components in TCM acting on different potassium channels to provide references for clinical drug use and development.

Abstract
Objective: To analyze the clinical features and prognosis of patients with cutaneous melanoma. Methods: The clinical data and follow-up data of 125 patients with cutaneous malignant melanoma (CMM) treated in the Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology between February 2008 and August 2019 were collected. Kaplan-Meier method and Log rank test were used for survival analysis, and Cox proportional risk regression model was used for impact factor analysis. Results: Among the 125 patients, 12 were stage Ⅰ, 62 were stage Ⅱ, 30 were stage Ⅲ, and 21 were stage Ⅳ; 76 were acral and 49 were non-acral. The median survival time was 44 months, and the 1-, 2-, and 5-year survival rates were 85.4%, 63.2% and 38.7%, respectively. Kaplan-Meier univariate survival analysis showed that Karnofsky performance status score, tumor stage, primary site, vascular infiltration, Ki-67, BRAF, lactate dehydrogenase (LDH), and surgical treatment were related to the prognosis of patients (P<0.05). The median overall survival (OS) time of patients receiving interferon treatment was 53 months, which was better than 40 months of patients not receiving interferon treatment, but the difference was not statistically significant (P=0.448). Among stage Ⅲ patients, the median OS time of patients receiving interferon therapy was 40 months, which was better than 17 months of patients not receiving interferon therapy (P=0.012). Among stage Ⅱ patients, the 1-, 2-, and 5-year survival rates of acral patients were 97.1%, 84.7%, and 65.8%, and the 1-, 2-, and 5-year survival rates of non-acral patients were 93.3%, 70.0% and 17.0%. The prognosis of patients with stage Ⅱ acral type was better than that of non-acral type (P=0.043). The median survival time of stage Ⅲ patients with acral type was 32 months, better than 17 months of non-acral type, but the difference was not statistical significance (P=0.164). The median survival time of acral type and non-acral type was 8 months and 11 months respectively (P=0.458). Cox multivariate analysis showed that tumor stage and preoperative LDH level were independent prognostic risk factors for cutaneous melanoma. Conclusions: Interferon treatment can improve the prognosis of patients with stage Ⅲ, and stage Ⅱ acral type patients have better prognosis than that of non-acral type patients. Tumor stage and preoperative LDH level were independent prognostic risk factors for cutaneous melanoma.

Abstract
IMPORTANCE The Mini-Clinical Evaluation Exercise (Mini-CEX) is highly recommended for assessing interns' performance. OBJECTIVE To develop a pediatric occupational therapy-specific Mini-CEX and examine its psychometrics. DESIGN Stage 1 had a retrospective design; Stage 2 had a prospective design. SETTING Pediatric occupational therapy unit in a hospital in Taiwan. PARTICIPANTS Thirty-four occupational therapy interns were evaluated with the Mini-CEX (physician version), and 57 were evaluated with the occupational therapy-specific Mini-CEX. OUTCOMES AND MEASURES The occupational therapy-specific Mini-CEX was developed with seven items on a 9-point scale categorized into three levels (unsatisfactory, satisfactory, highly satisfactory). RESULTS In Stage 1, the frequency of Mini-CEX (physician version) items receiving a rating of not applicable ranged from 1.9% to 88.1%. In Stage 2, the frequency of occupational therapy-specific Mini-CEX items receiving a rating of not applicable ranged from 3.5% to 31.6%. With the theme of evaluation taken into consideration, the frequency of not-applicable ratings was 0% to 8.8%. For the occupational therapy-specific Mini-CEX, content validity (item-level content validity index = 1, scale-level content validity index = 1) and internal consistency (Cronbach's α = .93) were excellent. The interns' scores on the second evaluation were significantly higher than those on their first evaluation, indicating good discriminant validity. CONCLUSIONS AND RELEVANCE The occupational therapy-specific Mini-CEX appears to be reliable and valid, and it is appropriate for evaluating interns' skills and attitudes in pediatric occupational therapy practice. What This Article Adds: The results support the development of the occupational therapy-specific Mini-CEX and its application in pediatric internship training.

Abstract
Glucagon-like peptide-1 (GLP-1) is easily degraded by dipeptidyl peptidase-4 (DPP-4) in the human body, limiting its therapeutic effect on type II diabetes. Therefore, improving GLP-1 receptor agonist (GLP-1RA) stability is a major obstacle for drug development. We analyzed human GLP-1, DPP-4, and GLP-1 receptor structures and designed three GLP-1RAs, which were introduced into fusion protein fragments and changed in the overall conformation. This modification effectively prevented GLP-1RAs from entering the DPP-4 active center without affecting GLP-1RAs’ ability to bind to GLP-1R, the new GLP-1RA hypoglycemic effect lasting for >24 h. Through molecular modeling, molecular dynamics calculation, and simulation, possible tertiary structure models of GLP-1RAs were obtained; molecular docking with DPP-4 and GLP-1R showed access to the fusion protein. The overall conformational change of GLP-1RAs prevented DPP-4 binding, without affecting GLP-1RAs’ affinity to GLP-1R. This study provides important drug design ideas for GLP-1RA development and a new example for application of structural biology-based protein design in drug development.

Abstract
IMPORTANCE The Objective Structured Clinical Examination (OSCE) is a highly valued measure of students' clinical competencies in medical education. However, few studies have reported on the administration of the OSCE in pediatric occupational therapy education. OBJECTIVE To describe the development of a pediatric occupational therapy OSCE station to evaluate students' use of a standardized assessment and examine its standard setting, failure rates, and psychometric properties. DESIGN Prospective, cross-sectional, observational study design. SETTING Three OSCE stations in a university clinical skills center. PARTICIPANTS Five experienced occupational therapists, 60 examinees, 44 child standardized patients, 44 chaperones, and 15 examiners. MEASURES The sum of the rating scale and the global performance scores were used. The rating scale measured the examinee's clinical competences in administering a standardized assessment. The 5-point global performance score was used to evaluate the examinee's whole performance. RESULTS The OCSE station's expert validity was acceptable (item-level content validity index [CVI] = 0.8-1.0; scale-level CVI = 0.98). Passing scores according to the Angoff method (passing score = 14) and the contrasting-groups M-SD method (passing score = 13) were similar. Failure rates were high (61.7%-73.3%). Internal consistency was acceptable (Cronbach's α = .78). No significant examiner effect was found (p = .554), and interexaminer reliability was acceptable (item score = 0.58-1.00; sum of the rating scale score = 0.97; global performance score = 0.79). CONCLUSIONS AND RELEVANCE The OSCE station for using a standardized assessment is a reliable and valid measure of students' interpersonal communication skills and assessment skills. What This Article Adds: The OSCE for education in pediatric occupational therapy is both effective and rigorous.

Abstract
Objective: To study the effect of hydroxyapatite (HA) based agents on the bonding properties of universal adhesive with different application modes, and to provide evidence for the use of adhesives after desensitization treatment. Methods: Sixty impacted third molars were extracted and selected (acquired from Department of Oral and Maxillofacial Surgery, College of Stomatology, Xi'an Jiaotong University). Four third molars were used to prepare 1 mm thick dentin disks and treated with 1% citric acid to simulate sensitive tooth models. The dentin surfaces were observed by scanning electron microscope (SEM) after treating with no desensitization (control group), desensitized by HA based toothpaste Biorepair and Dontodent Sensitive respectively (desensitizing toothpaste A group and B group), or HA paste treatment (desensitizing paste group ) (n=2 per group). The remaining teeth were selected to expose the mid-coronal dentin and establish dentin sensitivity models. Then, the specimens were divided into 4 former groups and received corresponding treatment. Each group was randomly divided into 2 subgroups, and intermediately strong universal adhesive (G-Premio Bond) was applied on the desensitized dentin by either etch-and-rinse mode or self-etch mode. Resin-dentin slice specimens (n=4 per subgroup), microtensile specimens (n=20 per subgroup) and slice specimens (n=6 per subgroup) were prepared. The microstructure and nanoleakage of the adhesive interfaces were observed by scanning electron microscopy (SEM). The microtensile strength (bond strength) and fracture mode were tested and recorded. The water permeability of the adhesive interface was observed by laser scanning confocal microscopy (LSCM). Results: SEM showed that desensitizing toothpaste and desensitizing paste could partially or entirely occlude most of the dentin tubules. For the etch-and-rinse mode, the bond strength of specimens treated with toothpaste A [(40.98±4.60) MPa], toothpaste B [(40.89±4.64) MPa] and HA paste [(41.48±3.65) MPa] was significantly higher than that of the control group [(38.58±4.28) MPa] (F=3.89,P<0.05). There was no statistically significant difference in bond strength among the 4 subgroups for self-etch modes (F=0.48,P>0.05). After desensitization, the bond strength of the control group and desensitizing groups in the self-etch mode was significantly higher than that in the etch-and-rinse mode (P<0.05). The overall fracture modes were mixed failure and interfacial failure in the control group and desensitizing groups. SEM showed speckled silver-stained particles deposited along the bottom of the hybrid layer on the bond interface of etch-and-rinse mode, and there were few silver-stained particles deposited on the bond interface of self-etch mode. LSCM showed continuous linear penetration in the hybrid layer of etch-and-rinse mode subgroups and discontinuous linear penetration in the hybrid layer of self-etch mode subgroups. Conclusions: HA based desensitizers have no adverse effect on the bond strength of intermediately strong universal adhesive and show good bonding performance accompanied with the self-etch mode.

Abstract
Androgenetic complete hydatidiform moles (CHMs) are associated with an increased risk of gestational trophoblastic neoplasia. P57KIP2 expression in hydatidiform moles is thought to be a powerful marker for differentiating CHMs from partial hydatidiform moles (PHMs). However, since there are so few such families clinically, very few studies have addressed the importance of p57KIP2-positive in the diagnosis and prognosis of CHM. This study aimed to emphasize the significance of the accurate diagnosis of rare CHM and careful follow-up. The classification of the hydatidiform mole was based on morphologic examination and p57KIP2 expression was determined by p57KIP2 immunohistochemical staining. Copy number variation sequencing was used to determine the genetic make-up of the mole tissues. In addition, the short tandem repeat polymorphism analysis was used to establish the parental origin of the moles. Finally, whole-exome sequencing was performed to identify the causal genetic variants associated with this case. In one Chinese family, the proband had numerous miscarriages throughout her two marriages. Morphologic evaluation and molecular genotyping accurately sub-classified two molar specimens as uniparental disomy CHM of androgenetic origin. Furthermore, p57KIP2 expression was found in cytotrophoblasts and villous stromal cells. In the tissue, there were hyperplasia trophoblastic cells and heteromorphic nuclei. In this family, no deleterious variant genes associated with recurrent CHM were detected. It is important to evaluate the prognostic value of p57KIP2 expression in androgenetic recurrent CHM. This knowledge may help to minimize erroneous diagnosis of CHMs as PHMs, as well as making us aware of the need to manage potential gestational trophoblastic neoplasia.

Abstract
Myeloid sarcoma (MS) is a type of malignant tumor that originates in the bone marrow. This study reports on the treatment of an 11-year-old Uygur girl with a 15-day history of fever and paroxysmal cough, accompanied by right hip pain. During treatment, fatigue and anemia developed, physical strength decreased, and a few petechiae were seen in the lower extremities. Multiple enlarged lymph nodes were palpable in the neck, with slight congestion in the pharynx. Routine blood screening showed three major myeloid lineage abnormalities. Pathological examination revealed the presence of CD10 (-), CD99 (+), CD20 (+), CD3 (-), CD117 (weak+), CD34 (unclear location), TdT (-), Pax5 (-), Ki-67 (50%+), MPO (-), and CD43 (+). The patient was eventually diagnosed with isolated MS. After chemotherapy, no small particles were observed in bone marrow morphology. Complete remission was confirmed by flow cytometric detection of minimal residual disease. Genomic DNA was subjected to targeted sequencing of 236 gene panels to detect somatic mutations and the MSH6 c.3953_3954insAA p.R1318fs germline mutation. Unfortunately, the patient was subsequently lost to follow-up. To our knowledge, an MSH6 germline mutation had not previously been reported in children with MS, and we speculated that an MSH6 germline mutation led to genomic instability, triggering a somatic mutation in multiple genes and ultimately led to the development of MS in this patient. It is suggested that rare base abnormalities may be involved in the development of isolated myeloid sarcomas (IMS).

Abstract
BACKGROUND Phospholipid transfer protein (PLTP) belongs to the lipid transfer glycoprotein family. Studies have shown that it is closely related to Alzheimer's disease (AD); however, the exact effect and mechanism remain unknown. OBJECTIVE To observe the effect of PLTP overexpression on behavioral dysfunction and the related mechanisms in APP/PS1/Tau triple transgenic (3×Tg-AD) mice. METHODS AAV-PLTP-EGFP was injected into the lateral ventricle to induce PLTP overexpression. The memory of 3×Tg-AD mice and wild type (WT) mice aged 10 months were assessed using Morris water maze (MWM) and shuttle-box passive avoidance test (PAT). Western blotting and ELISA assays were used to quantify the protein contents. Hematoxylin and eosin, Nissl, and immunochemistry staining were utilized in observing the pathological changes in the brain. RESULTS 3×Tg-AD mice displayed cognitive impairment in WMW and PAT, which was ameliorated by PLTP overexpression. The histopathological hallmarks of AD, senile plaques and neurofibrillary tangles, were observed in 3×Tg-AD mice and were improved by PLTP overexpression. Besides, the increase of amyloid-β42 (Aβ42) and Aβ40 were found in the cerebral cortex and hippocampus of 3×Tg-AD mice and reversed by PLTP overexpression through inhibiting APP and PS1. PLTP overexpression also reversed tau phosphorylation at the Ser404, Thr231 and Ser199 of the hippocampus in 3×Tg-AD mice. Furthermore, PLTP overexpression induced the glycogen synthase kinase 3β (GSK3β) inactivation via upregulating GSK3β (pSer9). CONCLUSION These results suggest that PLTP overexpression has neuroprotective effects. These effects are possibly achieved through the inhibition of the Aβ production and tau phosphorylation, which is related to GSK3β inactivation.

Abstract
ABSTRACTSOur previous study first investigated feasibility of applying ultrasound (US) and microbubbles (MBs) via external auditory canal to facilitate drug delivery into inner ear. However, most drugs are in aqueous formulae and eliminated via Eustachian tubes after drug application. In this study, feasibility of sustained release of thermosensitive poloxamer 407 (P407)-based MB gel for US mediation-enhanced inner ear drug (dexamethasone, DEX) delivery was investigated. The sol-to-gel transition temperature showed that mixture of DEX and only 10% and 12.5% P407 in MBs can be used for in vitro and in vivo drug delivery experiments. In in vitro Franz diffusion experiments, the release rates of 12.5% P407-MBs + US groups in the model using DEX as the delivered reagent at 3 h resulted in values 1.52 times greater than those of 12.5% P407-MBs groups. In guinea pigs, by filling tympanic bulla with DEX in 12.5% P407-MBs (DEX-P407-MBs), USMB applied at post-treatment days 1 and 7 induced 109.13% and 66.67% increases in DEX delivery efficiencies, respectively, compared to the group without US. On the 28th day after US-mediated P407-MB treatment, the safety assessment showed no significant changes in the hearing thresholds and no damage to the integrity of cochlea or middle ear. These are the first results to demonstrate feasibility of US-modified liquid form DEX-P407-MB cavitation for enhancing permeability of round window membrane. Then, a gel form of DEX-P407-MBs was generated and thus prolonged the release of DEX in middle ear to maintain the therapeutic DEX level in inner ear for at least 7 days.

Abstract
Objective: To investigate the effect of histone deacetylase (HDAC) activity on connective tissue diseases (CTD) associated pulmonary fibrosis (PF) in mice. Methods: A single tracheal administration of bleomycin induced PF in C57BL/6J male mice was performed to establish a PF model. The experimental mice were divided into three groups: bleomycin group (group B, n = 16) which was given bleomycin A2 physiological saline solution 2.5 μl/g body weight, saline group (Group C, n = 16) which was given physiological saline solution 2.5 μl/g body weight and no operation group (group N, n = 16). At 7, 14 and 21 days after administration, the animals were randomly killed and their specimens were collected. The activity of HDAC2 and HDAC4 was detected by colorimetry. Hematoxylin-eosin staining was used to evaluate pulmonary alveolitis and Masson staining for pulmonary fibrosis. The variance, correlation and binary variable correlation were analyzed. Results: The HDAC2 activity in lung tissue of mice in the bleomycin group was significantly higher than that in the no operation group (2.00±0.40 vs 1.00±0.23, P<0.05) and the saline group (2.00±0.40 vs 1.48±0.33, P<0.05). The HDAC2 activity in the bleomycin group was significantly higher than that in the no operation group (2.40±0.28 vs 1.00±0.23, P<0.01, 2.23±0.41 vs 1.00±0.23, P<0.01) and the saline group (2.40±0.28 vs 1.39±0.23, P<0.05, 2.23±0.41 vs 1.35±0.42, P<0.05). The change trend of HDAC2 activity between the bleomycin group and the saline group was different. There was no significant difference in HDAC4 activity in lung tissue of mice between the bleomycin group, the no operation group and the saline group. 14 days after tracheal administration, HDAC4 activity in the bleomycin group and the saline group were significantly higher than that in the no operation group (1.18±0.36 vs 1.00±0.12, P<0.01, 1.09±0.33 vs 1.00±0.12, P<0.01). HDAC2 activity in lung tissue of mice was positively correlated with pathological scores of alveolitis (r=0.428, P<0.01) and pulmonary fibrosis (r=0.508, P<0.01). HDAC4 activity in lung tissue of mice was positively correlated with the pathological scores of alveolitis (r=0.355, P<0.05) and pulmonary fibrosis (r=0.457, P<0.01). Binary linear regression analysis showed that HDAC2 activity had a stronger effect on the process of PF lesions than HDAC4 activity in lung tissue of mice. Conclusions: When pulmonary fibrosis occurred in mice, the activities of HDAC2 and 4 in pulmonary fibrosis were significantly increased. The activity of HDAC2 increased rapidly and lastingly, and the activity of HDAC4 fluctuated significantly and increased briefly. Changes in HDAC2 activity have stronger effects on alveolitis and fibrosis than HDAC4.

Abstract
This study aimed to create prognostic signatures to predict AML patients' survival using alternative splicing (AS) events. The AS data, RNA sequencing data, and the survival statistics of 136 AML patients were obtained from The Cancer Genome Atlas (TCGA) and TCGA SpliceSeq databases. Total 34,984 AS events generated from 8,656 genes, 2,583 of which were survival-associated AS events, were identified using univariate Cox regression. The prognostic models constructed using independent survival-associated AS events revealed that low-risk splicing better predicted patients' survival. ROC analysis indicated that the predictive efficacy of the alternate terminator model was best in the area under the curve at 0.781. Enrichment analysis revealed several important genes (TP53, BCL2, AURKB, PPP2R1B, FOS, and BIRC5) and pathways, such as the protein processing pathway in the endoplasmic reticulum, RNA transport pathway, and HTLV-I infection pathway. The splicing network of splicing events and factors revealed interesting interactions, such as the positive correlation between HNRNPH3 and CALHM2-13010-AT, which may indicate the potential splicing regulatory mechanism. Taken together, survival-associated splicing events and the prognostic signatures for predicting survival can help provide an overview of splicing in AML patients and facilitate clinical practice. The splicing regulatory network may improve the understanding of spliceosomes in AML.

Abstract
OBJECTIVE To compare the complete remission rate (CRR) and adverse reaction of the 3 different chemotherapy regimens (daunorubicin, idarubicin, imported idarubicin combined with cytarabine) for the treatment of adult patients with newly diagnosed non-M3 acute myeloid leukemia (AML). METHODS Seventy-one adult patients with newly diagnosed non-M3 AML were divided into 3 groups: 17 cases treated with daunorubicin plus cytarabine as group A, 24 cases treated with idarubicin plus cytarabine as group B, 30 cases treated with the imported idarubicin plus cytarabine as group C. The curative effects and adverse reactions were compared among the 3 groups after treatment. RESULTS CCR in group C (86.67%) was significantly higher than that in group A (52.94%) and group B (70.83%), and the CRR in group B was significantly higher than that in group A (P<0.05). The incidence of adverse reaction such as nausea, vomiting, myelosuppression and infection among 3 groups were not statistically significantant (P>0.05). CONCLUSION The curative effect of idarubicin for the treatment of non-M3 AML patients is better than that of daunorubicin, especially the curative efficiency of imported darubicin is much higher; the adverse reaction after treatment by daunorubicin and idarubicin can be controllable, so daunorubicin and idarubicin can be used as first-line drug for the patients with AML, and patients can choose more appropriate drug according to their own economic ability.

Abstract
Objective: To investigate the clinical effect of simplified drilling method and conventional drilling method in implants. Methods: A total of 46 patients (62 implants) were enrolled in this study that with dentition defect from May 2015 to May 2016 in the Implant department of Xi'an Jiao Tong University. The experimental group and the control group were randomly assigned according to the random number method, 23 cases in each group. The experimental group used the simplified drilling method (guided drill+ final drill), the control group using the conventional drilling method (step by step drill). The operation time, implant stability, marginal bone resorption rate and implant retention rate were compared between the two drilling methods. Results: The retention of the experiment group was 97% (31/32), the the control group was 100% (30/30). The operative time in the experiment group [(4.9±0.5) min] was significantly lower from the control group [(8.9±2.0) min] (P=0.000). There was no significant difference between the two methods in bone resorption (P=0.197), implant stability (P>0.05) and implant survival rate (P=0.492). Conclusions: The simplified drilling method can significantly reduce the operation time without compromising the clinical outcomes, and the osseointegration is well. The simplified drilling method should be used when sufficient bone mass, careful use in class II bone, forbidden in class I bone.

Abstract
Gamma-amino butyric acid (GABA) is an important bio-product used in pharmaceuticals, functional foods, and a precursor of the biodegradable plastic polyamide 4 (Nylon 4). Glutamate decarboxylase B (GadB) from Escherichia. coli is a highly active biocatalyst that can convert l-glutamate to GABA. However, its practical application is limited by the poor thermostability and only active under acidic conditions of GadB. In this study, we performed site-directed saturation mutagenesis of the N-terminal residues of GadB from Escherichia coli to improve its thermostability. A triple mutant (M6, Gln5Ile/Val6Asp/Thr7Gln) showed higher thermostability, with a 5.6 times (560%) increase in half-life value at 45 °C, 8.7 °C rise in melting temperature (Tm) and a 14.3 °C rise in the temperature at which 50% of the initial activity remained after 15 min incubation (T1550), compared to wild-type enzyme. Protein 3D structure analysis showed that the induced new hydrogen bonds in the same polypeptide chain or between polypeptide chains in E. coli GadB homo-hexamer may be responsible for the improved thermostability. Increased thermostability contributed to increased GABA conversion ability. After 12 h conversion of 3 mol/L l-glutamate, GABA produced and mole conversion rate catalyzed by M6 whole cells was 297 g/L and 95%, respectively, while those by wild-type GAD was 273.5 g/L and 86.2%, respectively.

Abstract
This study examined the treatment efficacy of proximal-emphasized robotic rehabilitation by using the InMotion ARM (P-IMT) versus distal-emphasized robotic rehabilitation by using the InMotion WRIST (D-IMT) in patients with stroke. A total of 40 patients with stroke completed the study. They received P-IMT, D-IMT, or control treatment (CT) for 20 training sessions. Primary outcomes were the Fugl-Meyer Assessment (FMA) and Medical Research Council (MRC) scale. Secondary outcomes were the Motor Activity Log (MAL) and wrist-worn accelerometers. The differences on the distal FMA, total MRC, distal MRC, and MAL quality of movement scores among the 3 groups were statistically significant (P = 0.02 to 0.05). Post hoc comparisons revealed that the D-IMT group significantly improved more than the P-IMT group on the total MRC and distal MRC. Furthermore, the distal FMA and distal MRC improved more in the D-IMT group than in the CT group. Our findings suggest that distal upper-limb robotic rehabilitation using the InMotion WRIST system had superior effects on distal muscle strength. Further research based on a larger sample is needed to confirm long-term treatment effects of proximal versus distal upper-limb robotic rehabilitation.

Abstract
OBJECTIVE To observe the efficacy and safety of the Chinese medicine (CM) Compound Zhuye Shigao Granule (, CZSG) on acute radiation-induced esophagitis (ARIE) in cancer patients. METHODS In a blinded, randomized, Kangfuxin Solution (, KFX)-controlled, single-centre clinical trial, 120 patients with lung, esophagus or mediastinal cancer were prospectively enrolled and assigned to the treatment group (60 cases) and control group (60 cases) by the random number table method. All patients received concurrent or sequential radiotherapy (2 Gy per day, 5 times per week, for 4 weeks) and were treated for 4 weeks since the radiation therapy. Patients in the treatment group were given 12 mg CZSG orally, thrice daily, while patients in the control group were given 10 mL KFX orally, thrice daily. The major indicators were observed, including the incidence and grade of esophagitis, time of occurrence and duration. Minor indicators were changes of CM symptoms, weight and Karnofsky Performance Status (KPS) Scale during 4 weeks from the beginning, recorded once a week. Blood routine examination and hepatorenal function were detected at the 2nd and 4th weeks. RESULTS The incidence and grade of ARIE were significantly decreased in the treatment group compared with the control group (P<0.05). CZSG appeared to significantly delay the time of ARIE occurrence and reduce the duration compared with KFX (P<0.05). The scores of CM symptoms, KPS and weight were improved significantly in the treatment group compared with the control group (P<0.05). There were no blood routine and hepatorenal function abnormal or obvious side-effects in both groups. Hemoglobin was improved and neutrophil and interleukin 6 were decreased in both groups after 4-week treatment compared with before treatment (P<0.05), and there was no significant difference between the two groups (P>0.05). CONCLUSIONS CZSG can decrease the incidence and grade of ARIE, delay the time of occurrence, reduce duration and alleviate the damage of ARIE. It is safe and effective in the prevention and cure of ARIE.

Abstract
Objective: To evaluate the efficacy and safety of intravenous thrombolytic therapy using reteplase in patients with acute ST-segment elevation myocardial infarction (STEMI). Method: A total of 73 hospitals from Henan province took part in this clinical trials during October 2012 to October 2014, 1 226 cases (1 014 male (82.7%), mean age 59.0 (51.0, 66.0) years) with acute STEMI received reteplase as thrombolytic agent.Reperfusion rate was judged according to the clinical symptoms, electrocardiogram, myocardial enzymes and heart rhythm, and the rate of cardiovascular events and bleeding events during hospitalization was also observed.Bleeding events were evaluated with global utilization of streptokinase and tissues plasminogen activator for occluded coronary arteries (GUSTO) criteria.Subgroup analysis was performed to compare the effects of various thrombolysis timing (time from onset to thrombolysis≤6 h or 6-12 h) on reperfusion rate, cardiovascular events and bleeding events rate. Results: The reperfusion rate was 89.3% (1 089/1 219) at 120 minutes after the thrombolysis, average recanalization time was (59.96±26.86) minutes.The reperfusion rate of ≤6 h thrombolysis group was significantly higher than in 6-12 hours group (90.3% (988/1094) vs. 80.8% (101/125), P=0.001), while in-hospital mortality (2.6%(28/1 094) and 0.8% (1/125), P=0.352) and rate of bleeding (5.9%(64/1 094) and 5.6%(7/125), P=0.910) were similar between the two groups. The total in-hospital mortality after thrombolysis was 2.4% (29/1219), which was significantly higher in failed recanalization group than in recanalization group (10.8%(14/130) vs. 1.4%(15/1089), P< 0.001). The total rate of bleeding after thrombolysis was 5.8% (71/1219), there were 3 severe bleeding cases according to GUSTO classification (0.2%), all of them were cerebral hemorrhage, and 2 out of 3 cases died. Conclusions: Reteplase use is related to high recanalization rate and low cardiovascular events and bleeding rate and our results thus show that reteplase is a safe and effective thrombolytic agent for STEMI patients.

Abstract
OBJECTIVE The objective of this study was to assess the efficacy of exposing Rosenmüller valve during endonasal endoscopic dacryocystorhinostomy (EES-DCR) in treating refractory nasolacrimal duct obstruction. METHODS Thirty six patients (47 eyes) with refractory nasolacrimal duct obstruction were entered into this study, including 13 patients (15 eyes) underwent nasal lacrimal duct intubation before, 18 patients (26 eyes) with small lacrimal sac, 2 patients underwent DCR before, 1 patient with functional nasal lacrimal duct obstruction, 1 patient with lacrimal mucocele, 1 patient with nasal trauma. During the DCR, the bone window was enlarged as wide as possible and the valve of Rosenmüller was exposed. The intubation of the lacrimal apparatus was performed if the lacrimal sac was very small and the Rosenmüller valve was tight. Functional endoscopic sinus surgery and septoplasty were performed simultaneously if necessary. Postoperatively, each patient was assessed by the symptom and nasal endoscopy. RESULTS The postoperative follow-up period ranged from 3 to 36 months. Thirty two patients(89.4%, 42/47 eyes) were cured, which presented as the disappearance of symptoms, the patency of the lacrimal ostium and the lacrimal duct irrigation was clear. One patient (2.1%, 1/47 eyes) was improved, which presented as the improvement of symptoms, a few hypertrophic scar around the lacrimal ostium and the lacrimal duct irrigation was clear. Four cases failed (8.5%, 4/47), which presented as symptomatic and obstruction of the lacrimal ostium. The total effective rate reached to 91.5%. No serious postoperative complications were found in all cases. CONCLUSIONS To expose Rosenmüller valve during endoscopic DCR in treating patients with refractory nasolacrimal duct obstruction could obviously increase the operative success rate, fewer complications, with no facial surgical scar. It is an ideal way to treat the refractory nasolacrimal duct obstruction.

Abstract
Long non-coding RNA (lncRNA) maternally expressed 3 (MEG3) is expressed in endothelial cells and involved in angiogenesis and vascular function. It was proposed that MEG3 participates in the process of endothelial progenitor cells (EPCs) functions in metabolic syndrome (MetS). In this study, the circulating EPCs number and function were decreased in MetS subjects. The MEG3 expression was expressed at a lower level and microRNA-140-5p (miR-140-5p) was expressed at a higher level in circulating EPCs of subjects with MetS. Pioglitazone reversed the alterations of EPCs function and the expression levels of MEG3 and miR-140-5p in EPCs. In bone marrow-derived EPCs exposed to palmitate, down-regulation of miR-140-5p canceled the increase of MEG3 expression level induced by Pioglitazone. Overexpression of MEG3 resulted in the down-regulation of miR-140-5p. The luciferase reporter assay and RIP assay showed that MEG3 targeted miR-140-5p. In addition, the HDAC7 expression levels were regulated by miR-140-5p and MEG3. These findings demonstrated that Pioglitazone up-regulated MEG3 expression to protect EPCs via decreasing miR-140-5p expression and increasing HDAC7 expression in MetS, which may be a novel therapeutic target for preventing and treating MetS.

Abstract
In the silkworm (Bombyx mori), tolerance to fluoride and scaleless wings are controlled by the dominant gene Dtf (dominant tolerance to fluoride) and recessive gene nlw (no Lepidoptera wings), respectively, and these genes have been mapped by using simple sequence repeat and sequence tag site markers. Marker-assisted evaluation and selection of silkworms with fluoride tolerance and scaleless wings were used for predicting fluoride resistance and scaleless wings in backcrossed animals. A silkworm strain was bred using this method, and its economic characteristics were found to be similar to those of commercial silkworms. These methods will therefore be useful for silkworm breeding programs and in screening for two or more characteristics of interest for segregating populations.

Abstract
Human sparganosis is a food borne zoonosis caused by the plerocercoid larvae (spargana) of various diphyllobothroid tapeworms of the genus Spirometra. Human infections are acquired by ingesting the raw or undercooked meat of snakes or frogs, drinking untreated water, or using raw flesh in traditional poultices. More than 1600 cases of sparganosis have been documented worldwide, mostly in east and southeast Asia. Sporadic cases have been reported in South America, Europe, and Africa, and several cases have been described in travellers returning from endemic regions. Epidemiological data suggest that the increased effect of sparganosis on human health is because of greater consumption of raw meat of freshwater frogs and snakes. This Review provides information about the Spirometra parasites and their lifecycles, summarises clinical features, diagnosis, and treatment of human sparganosis, and describes geographical distribution and infection characteristics of Spirometra parasites in host animals.

Abstract
Toxoplasmosis, caused by Toxoplasma gondii, is a parasitic zoonosis with worldwide distribution. The present study investigated the prevalence of T. gondii in dogs in Zhanjiang city, southern China, using both serological and molecular detection. A total of 364 serum samples and 432 liver tissue samples were collected from the slaughter house between December 2012 and January 2013 and were examined for T. gondii IgG antibody by ELISA and T. gondii DNA by semi-nested PCR based on B1 gene, respectively. The overall seroprevalence of T. gondii IgG antibody was 51.9%, and T. gondii DNA was detected in 37 of 432 (8.6%) liver tissue samples. These positive DNA samples were analyzed by PCR-RFLP at 3'- and 5'-SAG2. Only 8 samples gave the PCR-RFLP data, and they were all classified as type I, which may suggest that the T. gondii isolates from dogs in Zhanjiang city may represent type I or type I variant. This study revealed the high prevalence of T. gondii infection in dogs in Zhanjiang city, southern China. Integrated measures should be taken to prevent and control toxoplasmosis in dogs in this area for public health concern.

Abstract
AIM: To assess the efficacy of tenofovir disoproxil fumarate (TDF) in lamivudine (LAM)-resistant patients with a suboptimal response to LAM plus adefovir (ADV).
METHODS: We retrospectively analyzed the efficacy of switching to tenofovir disoproxil fumarate in suboptimal responders to lamivudine plus adefovir. Charts were reviewed for LAM-resistant chronic hepatitis B (CHB) patients who visited the Zhejiang Province People’s Hospital and The First Affiliated Hospital, College of Medicine, Zhejiang University, from June 2009 to May 2013. Patients whose serum hepatitis B virus (HBV) DNA remained detectable despite at least 6 mo of LAM plus ADV combination therapy were included. Patients with a suboptimal response to LAM plus ADV were randomized to switch to TDF monotherapy (300 mg/d orally; TDF group) or to continuation with LAM (100 mg/d orally) plus ADV (10 mg/d orally; LAM plus ADV group) and were followed for 48 wk. Serum HBV DNA was determined at baseline and weeks 4, 12, 24, 36, and 48. HBV serological markers and biochemistry were assessed at baseline and weeks 12, 24, and 48. Resistance surveillance and side effects were monitored during therapy.
RESULTS: Fifty-nine patient were randomized to switch to TDF (n = 28) or continuation with LAM plus ADV (n = 31). No significant differences were found between the groups at baseline. Prior to TDF therapy, all patients had been exposed to LAM plus ADV for a median of 11 mo (range: 6-24 mo). No difference was seen in baseline serum HBV DNA between the two groups [5.13 ± 1.08 log10 copies/mL (TDF) vs 5.04 ± 31.16 log10 copies/mL (LAM + ADV), P = 0.639]. There was no significant difference in the rates of achieving complete virological response (CVR) at week 4 between the TDF and LAM + ADV groups (17.86% vs 6.45%, P = 0.24). The rate of achieving CVR in the TDF and LAM plus ADV groups was 75% vs 16.13% at week 12, 82.14% vs 22.58% at week 24, 89.29% vs 25.81% at week 36, and 96.43% vs 29.03% at week 48, respectively (P < 0.001). The rate of alanine aminotransferase normalization was significantly higher in the TDF than in the LAM plus ADV group at week 12 (75% vs 17.86%, P < 0.001), but not at week 24 (78.57% vs 54.84%, P = 0.097) or 48 (89.26% vs 67.74%, P = 0.062). Patients were hepatitis B e antigen (HBeAg) positive at baseline. There was no significant difference in HBeAg negativity between the TDF and LAM plus ADV groups at week 48 (4% vs 0%, P = 0.481). There were no drug-related adverse effects at week 48 in either group.
CONCLUSION: Switching to TDF monotherapy was superior to continuous add-on therapy in patients with LAM-resistant CHB with a suboptimal response to LAM plus ADV.

Abstract
This study was aimed to analyze the serological characteristics, efficacy and safety of incompatible RBC transfusion in patients with autoimmune hemolytic anemia (AIHA). The patients with idiopathic or secondary AIHA were analyzed retrospectively, then the serological characteristics and the incidence of adverse transfusion reactions were investigated, and the efficacy and safety of incompatible RBC transfusion were evaluated according to the different autoantibody type and infused different RBC components. The results showed that out of 61 cases of AIHA, 21 cases were idiopathic, and 40 cases were secondary. 8 cases (13.1%) had IgM cold autoantibody, 50 cases (82.0%) had IgG warm autoantibody, and 3 cases (4.9%) had IgM and IgG autoantibodies simultaneously. There were 18 cases (29.5%) combined with alloantibodies. After the exclusion of alloantibodies interference, 113 incompatible RBC transfusions were performed for 36 patients with AIHA, total efficiency rate, total partial efficiency rate and total inefficiency rate were 56.6%, 15.1% and 28.3%, respectively. Incompatible RBC transfusions were divided into non-washed RBC group and washed RBC group. The efficiency rate, partial efficiency rate and inefficiency rate in non-washed RBC group were 57.6%, 13.0% and 29.4%, respectively. The efficiency rate, partial efficiency rate and inefficiency rate in washed RBC group were 53.6%, 21.4% and 25.0%, respectively. There was no significant difference of transfusion efficacy (P > 0.05) in two groups. Incompatible RBC transfusions were also divided into IgM cold autoantibody group and IgG warm autoantibody group. The efficiency rate, partial efficiency rate and inefficiency rate in IgM cold autoantibody group were 46.2%, 30.8% and 29.4%, respectively. The efficiency rate, partial efficiency rate and inefficiency rate in IgG warm autoantibody group were 56.7%, 13.4% and 29.9%, respectively. There was no significant difference of transfusion efficacy (P > 0.05 ) in two groups. Hemolytic transfusion reaction was not observed in all incompatible RBC transfusions. It is concluded that the same ABO type of non-washed RBC transfusion and O type washed RBC transfusion are all relatively safe for the AIHA patients with severe anemia after the exclusion of alloantibodies interference. There is no significant difference of transfusion efficacy in two groups. The same ABO type of non-washed RBC transfusion is more convenient and efficient than washed RBC transfusion, and excessive use of type O RBCs can also be avoided.

Abstract
Toll-like receptor 3 (TLR3) variants in mainland northern Chinese patients with polypoidal choroidal vasculopathy (PCV) and neovascular age-related macular degeneration (nAMD) were investigated. The complete genes of TLR3, including all exons and the promoter region, were assessed using direct sequencing technology of 284 unrelated mainland northern Chinese individuals: 96 nAMD patients, 92 PCV patients, and 96 controls. Six single nucleotide polymorphisms were identified: rs5743303, rs5743305, rs5743312, rs3775291, rs3775290, and rs6830345. The distribution of TLR3 genotypes for nAMD and PCV was not significantly different compared with normal controls. This study indicates that the TLR3 gene polymorphism is not associated with nAMD and PCV in northern Chinese patients.

Abstract
In the silkworm (Bombyx mori), resistance to the Zhenjiang (China) strain of the densonucleosis virus (DNV-Z) is controlled by the recessive gene nsd-Z (non-susceptible to DNV-Z), which is linked to 7 simple-sequence repeat markers. Marker-assisted evaluation and selection of DNV-Z-resistant silkworms were used for predicting DNV-resistance in backcrossed animals. A silkworm race was bred using this method, and its economic characteristics were found to be similar to those of commercial silkworm races. These markers will therefore be useful for silkworm breeding programs and in screening for densonucleosis resistance in segregating populations.

Abstract
Background Spirocerca lupi is a life-threating parasitic nematode of dogs that has a cosmopolitan distribution but is most prevalent in tropical and subtropical countries. Despite its veterinary importance in canids, the epidemiology, molecular ecology and population genetics of this parasite still remain unexplored. Methods The complete mitochondrial (mt) genome of S. lupi was amplified in four overlapping long fragments using primers designed based on partial cox1, rrnS, cox2 and nad2 sequences. Phylogenetic re-construction of 13 spirurid species (including S. lupi) was carried out using Bayesian inference (BI) based on concatenated amino acid sequence datasets. Results The complete mt genome sequence of S. lupi is 13,780 bp in length, including 12 protein-coding genes, 22 transfer RNA genes and two ribosomal RNA genes, but lacks the atp8 gene. The gene arrangement is identical to that of Thelazia callipaeda (Thelaziidae) and Setaria digitata (Onchocercidae), but distinct from that of Dracunculus medinensis (Dracunculidae) and Heliconema longissimum (Physalopteridae). All genes are transcribed in the same direction and have a nucleotide composition high in A and T. The content of A + T is 73.73% for S. lupi, in accordance with mt genomes of other spirurid nematodes sequenced to date. Phylogenetic analyses using concatenated amino acid sequences of the 12 protein-coding genes by BI showed that the S. lupi (Thelaziidae) is closely related to the families Setariidae and Onchocercidae. Conclusions The present study determined the complete mt genome sequence of S. lupi. These new mt genome dataset should provide novel mtDNA markers for studying the molecular epidemiology and population genetics of this parasite, and should have implications for the molecular diagnosis, prevention and control of spirocercosis in dogs and other canids.

Abstract
OBJECTIVES Compare histologic and biomechanical differences of tendon-to-bone healing between autologous and allogeneic bone transplants. MATERIALS AND METHODS Adult, healthy, New Zealand white rabbits were used to establish the extra-articular tendon-to-bone healing model with the left hind limb transplanted with allogeneic bone and the right hind limb transplanted with autologous bone. After 3, 6, and 12 weeks after the transplant, the rabbits were killed to collect tendon-to-bone specimens, and then the healing processes in tendon-to-bone interfaces were examined. RESULTS All rabbits grew well after incision without infection and can freely move. Histologic observations 3 and 6 weeks after surgery and biomechanical test results 6 weeks after surgery were statistically different between the autologous and the allogeneic transplants (P < .05). After 12 weeks, histologic observations and biomechanical test results showed no difference between the 2 transplants (P > .05). CONCLUSIONS Allogeneic bone transplant has a relatively slower tendon-to-bone healing than does autologous bone transplant, but finally allogeneic and autologous bone transplants have the same extent of tendon-to-bone healing.

Abstract
In this study, sequence variation in three mitochondrial DNA regions, namely cytochrome c oxidase subunit (cox1) and NADH dehydrogenase subunits 1 and 4 (nad1 and nad4), between Oesophagostomum dentatum and O. quadrispinulatum isolated from pigs in different geographical origins in Mainland China was examined, and their phylogenetic relationships were reconstructed. A partial of the cox1 (pcox1), nad1, and nad4 genes (pnad1 and pnad4) were amplified separately from individual nodule worms by PCR and were subjected to direct sequencing in order to define sequence variations. While the intraspecific sequence variations within each of the two species were 0.3-5.2% for pcox1, 0-4.9% for pnad1, and 0-7.1% for pnad4, the interspecific sequence differences were significantly higher, being 10.7-13.4% for pcox1, 11-14.6% for pnad1, and 14.9-18% for pnad4, respectively. There were a number of nucleotide positions in the pcox1, pnad1, and pnad4 sequences with no apparent intraspecific variation but distinct interspecific differences among those samples of Oesophagostomum spp. examined, which may be used as genetic makers for the identification and differentiation of the Oesophagostomum spp. Phylogenetic analyses using three inference methods, namely Bayesian inference, maximum likelihood, and maximum parsimony based on the combined sequences of pcox1, pnad1, and pnad4 revealed that the O. dentatum and O. quadrispinulatum form monophyletic groups, respectively. These findings demonstrated clearly the usefulness of the three mitochondrial sequences for studying systematics, population genetic structures, and the molecular ecology of Oesophagostomum spp.

Abstract
In the present study, the complete mitochondrial DNA (mtDNA) sequences of the pig nodule worm Oesophagostomum quadrispinulatum were determined for the first time, and the mt genome of Oesophagostomum dentatum from China was also sequenced for comparative analysis of their gene contents and genome organizations. The mtDNA sequences of O. dentatum China isolate and O. quadrispinulatum were 13,752 and 13,681 bp in size, respectively. Each of the two mt genomes comprises 36 genes, including 12 protein-coding genes, two ribosomal RNA and 22 transfer RNA genes, but lacks the ATP synthetase subunit 8 gene. All genes are transcribed in the same direction and have a nucleotide composition high in A and T. The contents of A+T are 75.79% and 77.52% for the mt genomes of O. dentatum and O. quadrispinulatum, respectively. Phylogenetic analyses using concatenated amino acid sequences of the 12 protein-coding genes, with three different computational algorithms (maximum likelihood, maximum parsimony and Bayesian inference), all revealed that O. dentatum and O. quadrispinulatum represent distinct but closely-related species. These data provide novel and useful markers for studying the systematics, population genetics and molecular diagnosis of the two pig nodule worms.

Abstract
The whipworm, Trichuris trichiura, causes trichuriasis in ∼600 million people worldwide, mainly in developing countries. Whipworms also infect other animal hosts, including pigs (T. suis), dogs (T. vulpis) and non-human primates, and cause disease in these hosts, which is similar to trichuriasis of humans. Although Trichuris species are considered to be host specific, there has been considerable controversy, over the years, as to whether T. trichiura and T. suis are the same or distinct species. Here, we characterised the entire mitochondrial genomes of human-derived Trichuris and pig-derived Trichuris, compared them and then tested the hypothesis that the parasites from these two host species are genetically distinct in a phylogenetic analysis of the sequence data. Taken together, the findings support the proposal that T. trichiura and T. suis are separate species, consistent with previous data for nuclear ribosomal DNA. Using molecular analytical tools, employing genetic markers defined herein, future work should conduct large-scale studies to establish whether T. trichiura is found in pigs and T. suis in humans in endemic regions.

Abstract
BACKGROUND C-Jun N-terminal kinase (JNK) signaling pathway plays a critical role in cerebral ischemia. Although the mechanistic basis for this activation of JNK1/2 is uncertain, oxidative stress may play a role. The purpose of this study was to investigate whether the activation of JNK1/2 is associated with the production of endogenous nitric oxide (NO). METHODS Ischemia and reperfusion (I/R) was induced by cerebral four-vessel occlusion. Sprague-Dawley (SD) rats were divided into 6 groups: sham group, I/R group, neuronal nitric oxide synthase (nNOS) inhibitor (7-nitroindazole, 7-NI) given group, inducible nitric oxide synthase (iNOS) inhibitor (2-amino-5,6-dihydro-methylthiazine, AMT) given group, sodium chloride control group, and 1% dimethyl sulfoxide (DMSO) control group. The levels of protein expression and phospho-JNK1/2 were detected by Western blotting and the survival hippocampus neurons in CA1 zone were observed by cresyl violet staining. RESULTS The study illustrated two peaks of JNK1/2 activation occurred at 30 minutes and 3 days during reperfusion. 7-NI inhibited JNK1/2 activation during the early reperfusion, whereas AMT preferably attenuated JNK1/2 activation during the later reperfusion. Administration of 7-NI and AMT can decrease I/R-induced neuronal loss in hippocampal CA1 region. CONCLUSION JNK1/2 activation is associated with endogenous NO in response to ischemic insult.

Abstract
Larvae of many holometabolous insects possess abdominal appendages called prolegs. Lepidoptera larvae have prolegs in the segments A3-A6. Functions of Lepidoptera hox genes on these abdominal appendages development is still a controversial issue. In this article, we report the use of double strand RNA (dsRNA)-mediated interference (RNAi) to dissect the function of some hox genes, specifically E-complex genes Ubx, abd-A, and Abd-B, in the ventral appendage development of the Lepidoptera silkworm, Bombyx mori. We found that Ubx RNAi caused leg identity in A1 segment, abd-A RNAi caused severe defect of abdominal prolegs and Abd-B RNAi allowed proleg identity in more posterior abdominal segments. These results confirm that Lepidoptera hox genes Ubx and Abd-B have evolved the repressing function to ventral appendage development, which is similar to those of Drosophila. However, Lepidoptera abd-A might have been modified distinctively during evolution, and has important roles in directing the development of prolegs.

Abstract
BACKGROUND In vitro culture (IVC) and IVF of preimplantation mouse embryos are associated with changes in gene expression. It is however not known whether ICSI has additional effects on the transcriptome of mouse blastocysts. METHODS We compared gene expression and development of mouse blastocysts produced by ICSI and cultured in Whitten's medium (ICSI(WM)) or KSOM medium with amino acids (ICSI(KSOMaa)) with control blastocysts flushed out of the uterus on post coital Day 3.5 (in vivo). In addition, we compared gene expression in embryos generated by IVF or ICSI using WM. Global pattern of gene expression was assessed using the Affymetrix 430 2.0 chip. RESULTS Blastocysts from ICSI fertilization have a reduction in the number of trophoblastic and inner cell mass cells compared with embryos generated in vivo. Approximately 1000 genes are differentially expressed between ICSI blastocyst and in vivo blastocysts; proliferation, apoptosis and morphogenetic pathways are the most common pathways altered after IVC. Unexpectedly, expression of only 41 genes was significantly different between embryo cultured in suboptimal conditions (WM) or optimal conditions (KSOM(aa)). CONCLUSIONS Our results suggest that fertilization by ICSI may play a more important role in shaping the transcriptome of the developing mouse embryo than the culture media used.
