Abstract
We report the results of a search for the rare, purely leptonic decay B^{-}→μ^{-}ν[over ¯]_{μ} performed with a 711 fb^{-1} data sample that contains 772×10^{6} BB[over ¯] pairs, collected near the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider. The signal events are selected based on the presence of a high momentum muon and the topology of the rest of the event showing properties of a generic B-meson decay, as well as the missing energy and momentum being consistent with the hypothesis of a neutrino from the signal decay. We find a 2.4 standard deviation excess above background including systematic uncertainties, which corresponds to a branching fraction of B(B^{-}→μ^{-}ν[over ¯]_{μ})=(6.46±2.22±1.60)×10^{-7} or a frequentist 90% confidence level interval on the B^{-}→μ^{-}ν[over ¯]_{μ} branching fraction of [2.9,10.7]×10^{-7}.

Abstract
WHAT IS KNOWN AND OBJECTIVE Jintrolong® is a pegylated recombinant human growth hormone (rhGH) (PEG-rhGH) developed for weekly subcutaneous (sc) injection. The current human tolerability trial and pharmacokinetics (PK) trial evaluated the safety, tolerability and PK of single-dose Jintrolong® injection in healthy adult subjects. METHODS Both trials were single-centre, randomized, open-label and single-dose studies. In the human tolerability trial, 34 healthy subjects were randomized to receive single-dose Jintrolong® sc injection (0.01, 0.06, 0.2, 0.5 or 0.8 mg/kg) or placebo. In the PK study, 30 healthy male subjects were evenly randomized into 3 groups to receive single-dose Jintrolong® sc injection (0.1, 0.2 or 0.4 mg/kg), and the subjects receiving 0.4 mg/kg Jintrolong® were given a single sc injection of conventional rhGH (0.067 mg/kg) after a 14-day washout period. Safety and PK profiles of Jintrolong® were evaluated. RESULTS AND DISCUSSION Jintrolong® was well tolerated with no serious adverse events or local injection responses. The PK trial showed that the plasma growth hormone concentration elevated quickly and stayed at peak level between 12 and 48 hours post-Jintrolong® injection, then decreased gradually back to baseline within 168 hours. Compared to single-dose conventional rhGH, Jintrolong® at all doses demonstrated significantly longer half time and time to maximum plasma concentration, lower clearance and higher systemic drug exposure, indicating prolonged presence of GH in the subjects' circulation. Additionally, systemic exposure to Jintrolong® increased in a dose-dependent manner. WHAT IS NEW AND CONCLUSION Single-dose Jintrolong® injection was well tolerated in healthy adult subjects, and the maximum tolerable dose was no lower than 0.8 mg/kg. Jintrolong® was long-acting with the potential for weekly administration.

Abstract
Objective: To study the accuracy of preoperative-ASSR in predicting behavioral thresholds of children at low age with profound hearing loss and to evaluate the feasibility of using hearing aids in non-operating ear after the cochlear implantation.Method: Children aged less than 2 years old at the time of surgery were selected as study subjects.The preoperative ASSR response threshold in 0.5, 1.0, 2.0 and 4.0 kHz were recorded.The play audiometry test was used to get the non operative ear behavioral thresholds of the children after three years old. Altogether 179 children with good cooperation and reliable results were enrolled in this study. The results of behavioral thresholds were made a comparison with the results of ASSR response threshold with corresponding frequency before operation for statistical analysis.Result: The behavioral threshold is better than corresponding ASSR response threshold with significant differences(P<0.01). Prediction rates of ASSR response threshold corresponding to behavioral thresholds from 0.5 kHz to 4.0 kHz are 49.7%, 70.9%, 59.2% and 60.9%.There are cases at all frequencies where ASSR showed no reaction but a behavioral thresholds were detected. The proportions of undrawn ASSR reaction at each frequency were 83.3%,75.5%,64.9%,45.1%.Conclusion: In profound hearing loss, the deviation between preoperative ASSR response thresholds and postoperative behavioral thresholds exists, especially in low frequency. No ASSR reaction in clinic cannot represent that there is no measurable hearing threshold. We suggest children at low age continue to wear hearing aids in the non operative ear after cochlear implantation. Whether to give up hearing aids should be judged after gaining the behavioral audiometry to avoid missing the bimodal opportunity.

Abstract
AIM To explore the role of computed tomography (CT) texture analysis in predicting pathologic stage of gastric cancers. MATERIALS AND METHODS Preoperative enhanced CT images of 153 patients (112 men, 41 women) with gastric cancers were reviewed retrospectively. Regions of interest (ROIs) were manually drawn along the margin of the lesion on the section where it appeared largest on the arterial and venous CT images, which yielded texture parameters, including mean, maximum frequency, mode, skewness, kurtosis, and entropy. Correlations between texture parameters and pathological stage were analysed with Spearman's correlation test. The diagnostic performance of CT texture parameters in differentiating different stages was evaluated using receiver operating characteristic (ROC) analysis. RESULTS Maximum frequency in the arterial phase and mean, maximum frequency, mode in the venous phase correlated positively with T stage, N stage, and overall stage (all p<0.05) of gastric cancer. Entropy in the venous phase also correlated positively with N stage (p=0.009) and overall stage (p=0.032). Skewness in the arterial phase had the highest area under the ROC curve (AUC) of 0.822 in identifying early from advanced gastric cancers. Multivariate analysis identified four parameters, including maximum frequency, skewness, entropy in the venous phase, and differentiation degree from biopsy, for predicting lymph node metastasis of gastric cancer. The multivariate model could distinguish gastric cancers with and without lymph node metastasis with an AUC of 0.892. CONCLUSION Multiple CT texture parameters, especially those in the venous phase, correlated well with pathological stage and hold great potential in predicting lymph node metastasis of gastric cancers.

Abstract
Bisphenol A (BPA) is an endocrine disrupter which has adverse effects on male reproduction. Aquaporins (AQPs), well known water-selective channels, play important roles in spermatogenesis and sperm functions. However, whether AQPs participate in the process that BPA induces abnormal sperms has not been investigated to date. In the present study, adult male rare minnows Gobiocypris rarus were exposed to environmentally relevant concentrations BPA (15 and 225 μg/L) for 1, 2 and 3 weeks. Results showed that BPA exposure disrupted sperm motility, increased the percentage of abnormal sperm cells, and decreased sperm tolerance to hypotonic solution and sperm fertilization capacity. Meanwhile, protein levels of AQPs were up-regulated, and their distribution in the testis was abnormal following BPA exposure. The following chromatin immune coprecipitation showed that BPA could regulate aqp3 and 8 expression through the ERE in their 5'-flanking region. The present study demonstrated that BPA could decrease the sperm quality in rare minnow, and AQP3 and 8 might play significant roles in this process.

Abstract
Objective: To investigate the therapeutic efficacy of tonsillectomy for patients with recurrence of IgA nephropathy (IgAN) after kidney transplantation. Methods: From May 2014, tonsillectomy was performed in 11 renal transplant patients with biopsy-proved recurrent IgAN. In a median follow-up of 14 (4-38) months, data of proteinuria, hematuria, estimated glomerular filtration rate (eGFR), and serum levels of IgA in these patients were compared before and after tonsillectomy.Patient's survival and renal graft survival were also summarized. Results: A remission of proteinuria was observed in 8 patients after tonsillectomy, and this status maintained well in the subsequent follow-up.Three patients had no or minimal reduction of proteinuria after tonsillectomy and returned to dialysis within 1 year after tonsillectomy.Possible causes could be severe primary IgAN of crescentric glomerulonephritis, IgAN recurrence in kidney retransplantation, and late tonsillectomy after IgAN recurrence.Serum levels of IgA significant decreased and no patients developed acute rejection or infection after tonsillectomy.In the 1-year follow-up, no patients died and grafts survived well in 8 out of 11 patients. Conclusions: Tonsillectomy may represent an effective and reliable way to treat recurrence IgAN after kidney transplantation, and may be applied widely in the future clinical management. However, early intervention is critical and effects may depend on the pathological features of primary IgAN.

Abstract
Objective:To study the auditory language ability of children with artificial cochlea after entering normal schools as well as the school life conditions and to evaluate the long-term comprehensive benefits of surgery on children along with their families. Method:The questionnaire was designed referring to the categories of auditory performance (CAP), the speech intelligibility rating (SIR), and family burden scale of diseases (FBS), with the questions involving four aspects of the general conditions, the auditory language ability, the school life conditions and the family conditions. Altogether 50 families were participated. Children who had applied artificial cochlea for at least two years and studied in normal schools were selected as the studying objects. The follow-up questionnaire was conducted on the parents. The differences were compared in the auditory language ability and the school life conditions, grouped by gender, age at surgery, parents' educational level, residence, service time of artificial cochlea and parent-child time in general. Meanwhile, the differences of 15 family conditions were compared before and after surgery. Result:The variable factors were of no obvious statistical significance in the comparison among groups of the auditory language ability (P>0.05); In the comparison of the school life conditions, there were significant differences in the number of making friends when grouped by parent-child time (P<0.05), there wes no statistical significance in the comparison among groups of the remaining various factors (P>0.05); In the comparison of family conditions before and after surgery, the rest of the indexes were of significant differences (P<0.05), there was no significant differences in the economic burden and social time of parents (P>0.05). Family conditions improved evidently after surgery. Conclusiont:Under the circumstances of different variable factors, after 2 years of rehabilitation, children are able to acquire better auditory language ability, and adjust themselves to the school life, finishing their studies, still there is a deficiency in the aspect of organizational competence in comparison to age-matched children. In addition, with children's recovery and attending schools, parents' mental stress is significantly reduced, family life returns to normal, and family atmosphere becomes harmonious. Not only can the artificial cochlea help rid children of disability, but also it can be of obvious benefits to their families.

Abstract
OBJECTIVE The manifestations of aging include cognitive deficits and muscular dysfunction, which are closely linked to impairment of mitochondrial biogenesis. Berberine, an isoquinoline alkaloid, presents multiple anti-diabetic pharmacological effects. Evidence has indicated that insulin resistance and cognitive impairment share the same pathogenesis, and berberine could reverse glucose metabolism abnormalities and muscle mitochondrial dysfunction induced by a high-fat diet. This study was used to investigate whether berberine could be used as an anti-aging drug to prevent cognitive deficits and muscular dysfunction in natural aging. METHODS Biochemical indicators and an intraperitoneal glucose tolerance test were tested in 5-month-old rats (5 mo group), 24-month-old rats (24 mo group) and 24-month-old rats that had undergone 6 months of berberine treatment (BBR group). A Morris water maze test was conducted to assess the cognitive ability of the rats. Insulin resistance in whole-body was evaluated by intraperitoneal glucose tolerance test (IPGTT). The morphology of the skeletal muscle tissue was observed by hematoxylin-eosin (HE) staining. The levels of total cholesterol, triglyceride, ATP and reactive oxygen species (ROS) were assessed with corresponding reagent kits. The protein expressions of GLUT4, AMPK, SIRT1 and PGC-1α in skeletal muscle were examined by Western blot. RESULTS The results showed that administration of berberine for 6 months significantly improved cognitive deficits and insulin resistance in naturally aging rats (p<0.01). Furthermore, berberine treatment helped normalize the disordered alignment and the decreased number of muscle fibers (p<0.01) in the skeletal muscle of 24 mo rats. Berberine decreased the levels of ROS in both the serum and the skeletal muscle of 24 mo rats (p<0.01). Berberine increased the protein expression of p-AMPK, SIRT1 and PGC-1α and increased the production of ATP in the skeletal muscle of aging rats (p<0.01). CONCLUSIONS Berberine markedly ameliorates aging-related reductions in cognitive ability and muscular function, and the activation of the AMPK/SIRT1/PGC-1α pathway in skeletal muscle may be the underlying protective mechanism of berberine on muscular function.

Abstract
Vitellogenins (Vtgs) are major precursor of the egg-yolk proteins. They are synthesized in liver of adult female ovipara, but normally silent in males. For their sensitive response to estrogen, Vtgs are usually used as biomarkers for environmental estrogenic compounds. In the present study, three vtg subtypes (vtg1, vtg2 and vtg3) were proved to present in the testis of rare minnow Gobiocypris rarus for the first time. Immunohistochemistry result showed that Vtg proteins mainly deposit in spermatogonium and spermatocytes. Following 225μg/L bisphenol A (BPA) exposure 1, 3 and 9 weeks, testicular vtg mRNAs were mostly significantly decreased. The further chromatin immunoprecipitation showed that BPA could decrease estrogen receptor (Er) recruitment in vtg promoter, which possibly reduced Er's transcription activation effect on vtgs. However, different from the continuously decreased vtg mRNA levels, testicular Vtg protein levels were recovered at week 9. Considering the induced hepatic Vtg expression, testicular Vtgs may be replenished by the induced hepatic Vtgs under BPA exposure.

Abstract
We compare element and isotopic fractionations measured in solar wind samples collected by NASA's Genesis mission with those predicted from models incorporating both the ponderomotive force in the chromosphere and conservation of the first adiabatic invariant in the low corona. Generally good agreement is found, suggesting that these factors are consistent with the process of solar wind fractionation. Based on bulk wind measurements, we also consider in more detail the isotopic and elemental abundances of O. We find mild support for an O abundance in the range 8.75 - 8.83, with a value as low as 8.69 disfavored. A stronger conclusion must await solar wind regime specific measurements from the Genesis samples.

Abstract
RATIONALE Studies have implied the positive association of JAK2/STAT3 signaling with the onset and severity of acute pancreatitis (AP). However, definitive functional study of JAK2/STAT3 signaling in the pathogenesis of acute pancreatitis in vivo is missing and its potential as a therapeutic target and the underlying mechanisms remain to be determined. OBJECTIVES The aim of this study was to explore the role of JAK2/STAT3 signaling in the pathogenesis of hyperlipidemia-intensified caerulin-induced AP and its potential as a therapeutic target. METHODS AND RESULTS Using the caerulin-induced acute pancreatitis rat model, we showed that JAK2/STAT3 signaling was activated in pancreas and systemic inflammation was increased during AP. Pharmacological suppression of JAK2 by its inhibitor AG490 robustly protected against tissue damage, attenuated JAK2/STAT3 signaling and inflammatory responses. Local pancreatic tissue damage and phosphor- JAK2 in the pancreatic tissue were enhanced in animals fed with high fat diet compared to chow-diet fed animals. Interestingly, JAK2 inhibitor AG490 significantly inhibited pancreas necrosis and systemic inflammation in animals fed with high fat or chow-diet, but did not affect STAT3 signaling. CONCLUSION These results establish that JAK2 activation plays a significant role in the pathogenesis of caerulin-induced AP in animals on both chow and high-fat diets by regulating necrosis and systemic inflammation. Thus, our results not only clarify novel signaling mechanisms in AP but also suggest that JAK2 might constitute a target in the management of hyperlipidemia-intensified caerulin-induced AP.

Evidence for Isospin Violation and Measurement of CP Asymmetries in B→K^{*}(892)γ. PHYSICAL REVIEW LETTERS 2017; 119:191802.

Abstract
We report the first evidence for isospin violation in B→K^{*}γ and the first measurement of the difference of CP asymmetries between B^{+}→K^{*+}γ and B^{0}→K^{*0}γ. This analysis is based on the data sample containing 772×10^{6}BB[over ¯] pairs that was collected with the Belle detector at the KEKB energy-asymmetric e^{+}e^{-} collider. We find evidence for the isospin violation with a significance of 3.1σ, Δ_{0+}=[+6.2±1.5(stat)±0.6(syst)±1.2(f_{+-}/f_{00})]%, where the third uncertainty is due to the uncertainty on the fraction of B^{+}B^{-} to B^{0}B[over ¯]^{0} production in ϒ(4S) decays. The measured value is consistent with predictions of the standard model. The result for the difference of CP asymmetries is ΔA_{CP}=[+2.4±2.8(stat)±0.5(syst)]%, consistent with zero. The measured branching fractions and CP asymmetries for charged and neutral B meson decays are the most precise to date. We also calculate the ratio of branching fractions of B^{0}→K^{*0}γ to B_{s}^{0}→ϕγ.

Abstract
Hypertension has a profound influence on the structure and function of blood vessels. Cerebral vessels undergo both structural and functional changes in hypertensive animals. However, dynamic changes of cerebrovasculature and the factors involved in this process are largely unknown. In this study, we explored the dynamic changes of vascular structure in hypertensive rats using novel synchrotron radiation angiography. Twenty-four spontaneously hypertensive rats (SHR) and 24 Sprague–Dawley (SD) rats underwent synchrotron radiation (SR) angiography. Each group had 8 animals. We studied the cerebral vascular changes in SHR over a time period of 3–12-month and performed quantitative analysis. No vascular morphology differences between SHR and SD rats were observed in the early stage of hypertension. The number of twisted blood vessels in the front brain significantly increased at the 9- and 12-month observation time-points in the SHR compared to the SD rats (p < 0.01). The vessel density of the cortex and the striatum in SHR was consistently higher than that in SD rats at time points of 3-, 9-, and 12-month (p < 0.001). Vascular elasticity decreased both in SHR and SD rats with aging. There were statistically significant differences in the relative vascular elasticity of extracranial/intracranial internal carotid artery, middle cerebral artery, posterior cerebral artery and anterior cerebral artery between SHR and SD rats at 12-month (p < 0.01). We concluded that the dynamic vascular alterations detected by SR angiography provided novel imaging data for the study of hypertension in vivo. The longer the course of hypertension was, the more obvious the vascular differences between the SHR and the SD rats became.
