Abstract
Objective: To summarize the clinical features of 7 rare cases of hemolytic disease of newborn (HDN), and to improve the understanding of rare HDN. Methods: Data of clinical information, laboratory findings, treatments and outcomes were collected and analyzed for four cases with HDN due to anti-M, two cases due to anti-Kidd, and one case due to anti-Duffy. All of them were admitted to the Department of Neonatology, Beijing Children's Hospital Affiliated to Capital Medial University from July 2007 to June 2017. Results: Among the four MN hemolytic babies, two were males and two were females. Jaundice was found in three cases. Two cases had hyperbilirubinemia, one of them had severe hyperbilirubinemia. All the four cases developed anemia, including severe anemia in three cases. Two cases of Kidd hemolytic disease and 1 case of Duffy hemolytic disease had jaundice and anemia, but did not reach the level of severe hyperbilirubinemia and severe anemia. MN hemolytic disease babies got negative results in direct antiglobulin test, whereas the Kidd and Duffy hemolytic disease babies had positive findings in direct antiglobulin test. None of the babies had blood transfusion, and they were discharged from the hospital. Conclusions: Without maternal and fetal blood group incompatibility (ABO or Rh blood-group system), for early onset of jaundice, severe jaundice or anemia, antiglobulin test to mother and child earlier should be administered, and MN, Kidd, Duffy and other rare hemolytic disease of the newborn should be pay attention to.

Abstract
The aim of this study was to evaluate the effects of antibiotic residues in milk on growth, ruminal fermentation, and microbial community of dairy calves in their first 35 d of age. Twenty newborn Holstein bull calves were assigned to 1 of 2 treatments equally: milk replacer without antibiotics (control) and milk replacer plus 4 antibiotics: 0.024 mg/L of penicillin, 0.025 mg/L of streptomycin, 0.1 mg/L of tetracycline, and 0.33 mg/L of ceftiofur (ANT). Starter intake and fecal consistency scores of each calf were recorded on a daily basis. Body weight, withers height, body length, and heart girth were measured on d 1, 7, 14, 21, 28, and 35 before feeding in the morning. Rumen fluid was collected on d 15, 25, and 35 to determine ruminal pH, volatile fatty acids (VFA), and NH3-N concentrations. A total of 10 (5 per treatment) samples of rumen fluid taken on d 35 were analyzed for microbial community. Rumen tissues from the cranial ventral sac and cranial dorsal sac were collected from 8 calves of each group for morphology analysis on d 35 after being harvested. The results showed that calves in 2 treatments had similar starter intake, body weight, withers height, body length, heart girth, and average daily gain. The ANT group showed a lower diarrhea frequency in wk 4, and no differences were found for other weeks. Calves in the ANT group exhibited a greater concentration of acetic acid in the rumen and no differences for other VFA, total VFA, rumen pH, or NH3-N. As for rumen morphology, the length of papillae from cranial ventral sac of the ANT group was longer than that of the control group. The results of ruminal microbial community showed that antibiotic residues had minor effects on bacteria phyla and bacteria diversity. At the genus level, calves in the ANT group showed lower richness of Prevotella and higher richness of Acetitomaculum. In conclusion, antibiotic residues stimulated the development of ruminal papillae and increased the production of acetic acid in rumen, which might be caused by the influence of antibiotics on the ruminal microbial community.

Abstract
Objective: To investigate the efficacy and outcome of transcatheter patent foramen ovale (PFO) closure in patients with cryptogenic stroke (CS). Methods: Sixty consecutive patients with cryptogenic stroke who undertook transcatheter PFO closure between May 2015 and September 2017 in Beijing Tiantan Hospital were enrolled in this prospective study.Transcranial Doppler (TCD) bubble test was performed and right-left shunt(RLS) was confirmed in all patients.Closure success rate,effective closure rate, complications, recurrence of ischemic stroke and new onset atrial fibrillation were evaluated. Results: A total of 60 patients (42 male,age range 24-68 (47±11)years) were included in the study.PFO size (motionless state) was (1.6±0.6)mm.RLS before closure was graded and 11 patients had moderate RLS and 48 patients had large RLS (include 41 patients who experienced shower or curtain effect).Closure success rate was 100% (60/60).No severe complications were observed.At 6 months,45 patients completed TCD bubble test.Of these, 4 patients suffered from moderate to large residual and thus effective closure rate was 91%(41/45).The mean follow-up period was 2-29 (median 12) months. During the follow-up, only 1 patient experienced recurrent cerebral infarction.New onset atrial fibrillation was not detected. Conclusion: Transcatheter PFO closure is effective,safe and related with a good outcome in reduction of recurrent CS for patients with PFO.

Abstract
Background Arthroscopic ankle arthrodesis (AAA) is recognized as the standard treatment for the end-stage ankle arthritis. Two-screw configuration fixation is a typical technique for AAA; however, no consensus has been reached on how to select most suitable inserted position and direction. For better joint reduction, we developed a new configuration (2 home run-screw configuration: 2 screws are inserted from the lateral-posterior and medial-posterior malleolus into the talar neck) and investigated whether it turned out to be better than the other commonly used 2-screw configurations. Methods In this study, we investigated three kinds of 2-screw configurations: 2 “home run”-screw configuration (group A), crossed transverse configuration (the screw is inserted from the medial malleolus into the anterior talus and the other from the lateral tibia maintains posterior talus, group B), and 2 parallel screw configuration (2 parallel screws are inserted from the posteromedial side of the tibia into talus, group C). The effects of the above three insertions on the loading stress of the tibio-talar joint were comparatively analyzed with a three-dimensional finite element model. Results Group A was better than groups B and C in respect of stress distribution uniformity and superior to both groups B and C in anti-flexion strength and anti-internal rotation strength. Group A was slightly worse than group C but better than group B in anti-dorsiflexion and anti-valgus and varus strength. Conclusions Two “home run”-screw configuration facilitates the reduction of anterior talus dislocation of end-stage ankle arthritis. Our finite element analysis demonstrates the configuration is superior to crossed transverse and parallel configuration for arthroscopic ankle arthrodesis in terms of stress distribution and initial stability.

Abstract
Objective: To compare the performance of Miseq and Ion Torrent PGM platforms and library construction method for next-generation sequencing (NGS) technology for formalin-fixed and paraffin-embedded (FFPE) samples. Methods: A total of 204 FFPE cancer samples including 100 non-small cell lung cancers at the First Affiliated Hospital of Zhejiang University, and 104 colorectal cancers at West China Hospital of Sichuan University were retrospectively selected from January 2013 to December 2016. By using the same samples, DNA was extracted, and the same amount of DNA was used for library construction with the same kit, and sequenced on Miseq and Ion Torrent PGM respectively, after passing the quality control. Any discordant mutations between two platforms were validated by amplified refractory mutation system-polymerase chain reaction (ARMS-PCR) method and Sanger sequencing. Results: A total of 204 FFPE samples were included and 197 samples were successfully analyzed by both platforms. The number of reads generated by the samples on Miseq platform sequencing was higher than PGM platform (median 391 634 vs. 298 030, P<0.01). Alignment with human reference genome showed that the mapping rate of Miseq platform was higher than PGM platform (median 100.0% vs. 99.7%, P<0.01). The median sequence depth of samples on Miseq was higher than PGM platform (median 853× vs. 698×, P<0.01). A total of 236 mutations were detected by two platforms, of which 221 were detected on both platforms, with a 93.6% concordance. Miseq platform detected 11 mutations not detected on PGM platform, while PGM platform detected 4 more mutations not detected on Miseq platform. With validation by ARMS-PCR and Sanger sequencing, Miseq platform was more reliable for low-frequency mutations. The main reasons for the discordant mutations between two platforms were that mutation frequency on undetected platform was lower than mutation reporting range (5%) and FFPE samples were stored for a long time. Conclusions: Compared with PGM, Miseq platform shows higher sequencing quality in terms of the number of reads, alignment results and coverage depth, and the test results are more reliable. In clinical practice, the appropriate platform should be chosen based on sample size and actual throughput requirements to aid in the molecular characterization of tumors.

Abstract
Objective: Abnormalities of lipid profile were considered as risk factors of hemorrhage after ischemic stroke. We aimed to determine the relationship between lipid levels and bleeding in minor stroke or transient ischemic attack (TIA) patients receiving antiplatelet therapy. Methods: Serum total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and triglyceride were tested in a subgroup of 3 044 consecutive patients from Clopidogrel in High-risk patients with Acute Non-disabling Cerebrovascular Events (CHANCE) trial. Patients were randomized to clopidogrel plus aspirin group or single aspirin group. The primary endpoint was any bleeding within 90 days. The secondary endpoint was severe bleeding according to the Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries (GUSTO) definition. Cox proportional hazards models were used to assess the associations of lipid levels and outcomes. Results: A total of 59 (1.9%) bleeding events occurred at 90 days. High-density lipoprotein cholesterol (adjusted HR=2.16; 95%CI 1.17-4.00, P=0.014) and age (adjusted HR=1.04; 95%CI 1.01-1.06, P=0.006) were significantly associated with any bleeding. High-density lipoprotein cholesterol was also associated with severe bleeding (adjusted HR=3.05; 95%CI 1.39-6.68, per 1 mmol/L increase). No correlations between outcomes and levels of total cholesterol, low-density lipoprotein cholesterol and triglyceride were found. There was no interaction of any lipid component level with randomized antiplatelet therapy. Conclusions: Elevated high-density lipoprotein cholesterol is independently associated with any bleeding and severe bleeding in the patients with acute minor stroke or high-risk TIA on antiplatelet therapy.

Abstract
Objective: To investigate whether small endoscopic biopsies of colorectal cancer were sufficient for quality and accurate mutational analysis by amplicon-based next-generation sequencing (NGS). Methods: By using an amplicon-based targeted NGS panel for mutational detection on Illumina Miseq platform, a total of 109 formalin-fixed and paraffin-embedded (FFPE) endoscopic biopsies of colorectal cancer were retrospectively selected, based on specific histopathologic criteria, from January 2012 to June 2016 at West China Hospital of Sichuan University and Peking University Third Hospital. Twelve of these biopsies had corresponding FFPE surgical resection specimens. Quality control parameters of NGS testing were analyzed and NGS results were confirmed by other methods. Mutation calls of the 12 paired endoscopic biopsies and surgical resections were compared. Results: Of the endoscopic biopsy specimens, 97.2% (106/109) had sufficient DNA and qualified sequencing library. NGS generated excellent sequencing data, with a median of 848× for median read depth and 95.7% for uniformity. The success rate of NGS was 95.4% (104/109). Conventional methods confirmed the results of NGS for KRAS and BRAF, and the concordance rate was 100.0%. The clinically actionable mutations detected in the 12 paired endoscopic biopsies and surgical resections were concordant. Conclusion: FFPE endoscopic biopsies of colorectal cancer is suitable for targeted NGS, providing quality sequencing data and accurate mutational information to guide targeted therapy.

Abstract
Background Chronic muscle injury is characteristics of fatty infiltration and fibrosis. Recently, fibro/adipogenic progenitors (FAPs) were found to be indispensable for muscular regeneration while were also responsible for fibrosis and fatty infiltration in muscle injury. Many myokines have been proven to regulate the adipose or cell proliferation. Because the fate of FAPs is largely dependent on microenvironment and the regulation of myokines on FAPs is still unclear. We screened the potential myokines and found Interleukin-15 (IL-15) may regulate the fatty infiltration in muscle injury. In this study, we investigated how IL-15 regulated FAPs in muscle injury and the effect on muscle regeneration. Methods Cell proliferation assay, western blots, qRT-PCR, immunohistochemistry, flow cytometric analysis were performed to investigate the effect of IL-15 on proliferation and adipogensis of FAPs. Acute muscle injury was induced by injection of glycerol or cardiotoxin to analyze how IL-15 effected on FAPs in vivo and its function on fatty infiltration or muscle regeneration. Results We identified that the expression of IL-15 in injured muscle was negatively associated with fatty infiltration. IL-15 can stimulate the proliferation of FAPs and prevent the adipogenesis of FAPs in vitro and in vivo. The growth of FAPs caused by IL-15 was mediated through JAK-STAT pathway. In addition, desert hedgehog pathway may participate in IL-15 inhibiting adipogenesis of FAPs. Our study showed IL-15 can cause the fibrosis after muscle damage and promote the myofiber regeneration. Finally, the expression of IL-15 was positively associated with severity of fibrosis and number of FAPs in patients with chronic rotator cuff tear. Conclusions These findings supported the potential role of IL-15 as a modulator on fate of FAPs in injured muscle and as a novel therapy for chronic muscle injury.

Abstract
Tuning multiple strain and polar states of ferroelectrics by using strain engineering is an essential approach for designing multifunctional electric devices such as multiple state memories. However, integrating multiple strain states is still a challenge, and in addition, revealing such strains and the resultant polar behaviors on the atomic level remains difficult. In this work we prepare PbZr0.52Ti0.48O3/PbTiO3 (PZT/PTO) superlattices on SrRuO3-buffered SrTiO3(001) substrates. Aberration-corrected high angle annular dark field scanning transmission electron microscopy (HAADF-STEM) reveals that the superlattice is coherent in both c (out-of-plane polar direction) and a (in-plane polar direction) domains. We find that the strain states of both PZT and PTO in c and a domains are variant, leading to four special strain states. For example, the tetragonality for PTO in c and a domains is 1.061 and 1.045, respectively. In contrast, PZT in c domains displays a tetragonality as giant as 1.107, which corresponds to 110 µC cm-2 spontaneous polarization, much larger than the bulk PZT; while PZT in a domains exhibits 1.010 tetragonality with about 70 µC cm-2 polarization. This study reveals a practical way to integrate multiple strain states and enhanced polarizations in ferroelectric films, which could be used as multifunctional electric elements.

Abstract
Objective:To analyze the characteristics of sleep quality and its correlation with the clinical features and hearing curative effects in patients with unilateral idiopathic sudden sensorineural hearing loss (ISSHL). Method:Pittsburgh sleep quality index (PSQI) was applied to evaluate the sleep quality of unilateral ISSHL patients in our department. Patient group is divided into poor sleep quality subgroup (total PSQI score>7 points) and normal sleep subgroup (total PSQI score≤7 points). The differences of Patient group and two subgroups between hearing curative effect in the 30 days after treatment and sleep quality scores were compared and analyzed. Questionnaire survey was applied to control group, which contained 70 healthy people with normal hearing level and age matched. Result:A total of 75 cases were collected. To compare with control group, there were statistical difference in the scores of subjective sleep quality, habitual sleep efficiency, sleep disturbance and PSQI before treatment and in the score of habitual sleep efficiency after the treatment for 30 d (P<0.05). The sleep quality between poor sleep quality subgroup and normal sleep subgroup, total therapeutic effect after treatment for 30 d was no significant difference (P>0.05). The proportion for poor sleep quality were no statistically significant differences in the different efficacy of two subgroups (P>0.05). Two subgroups before treatment, in addition to sleep duration, there were statistically significant in all the sleep quality dimensions (P<0.05); after treatment for 30 d, in addition to subjective sleep quality, sleep duration, all have statistical difference (P<0.05). The poor sleep quality subgroup in the case group compared before and after treatment for 30 d, there was statistically significant in subjective sleep quality (P<0.05). The sleep disturbance before treatment, the sleep duration and PSQI scores after treatment for 30 d were associated with clinical features in patients with unilateral ISSHL (P<0.05). Conclusion:The sleep quality of patients with Unilateral SSNHL was significantly lower than that of normal hearing patients, the sleep quality had no significant effect on the general efficacy of unilateral SSNHL, but some sleep quality dimensions are associated with the clinical features before and after treatment.

Abstract
Dirac node arc semimetal state is a new topological quantum state which is proposed to exist in PtSn4 (Wu et al 2016 Dirac node arcs in PtSn4 Nat. Phys. 12 667-71). We present a systematic de Haas-van Alphen quantum oscillation study on this compound. Two intriguing oscillation branches, i.e. F 1 and F 2, are detected in the fast Fourier transformation spectra, both of which are characterized to possess tiny effective mass and ultrahigh quantum mobility. And the F 2 branch exhibits an angle-dependent nontrivial Berry phase. The features are consistent with the existence of the node arc semimetal state and shed new light on its complicated Fermi surfaces and topological nature.

Abstract
Lymph node metastasis is a decisive factor for performing postoperative radiotherapy for oral squamous cell carcinoma (OSCC). However, whether OSCC patients with only micrometastasis need postoperative radiotherapy is unclear. In this study, OSCC patients (n = 311) with negative (n = 247), only micrometastasis (n = 44) and macrometastasis (n = 20) were detected and selected by HE staining. Micrometastasis was re-assessed using immunohistochemical staining of cytokeratin (CK) in HE-negative patients to find out the false negative cases. The results indicated that, among the negative lymph node cases (n = 247), the positive rate of CK was 4.94% (n = 12). Besides, the clinical features of the primary tumor in relation to the only micrometastatic status and the value of the postoperative radiotherapy on the only micrometastasis patients were evaluated. Patients with only micrometastasis had higher T stage and inferior worst pattern of invasion (WPOI) than patients without micrometastasis, but they had longer overall survival (OS), metastasis-free survival (MFS), and disease-free survival (DFS) than macrometastasis patients. However, the survival time of only micrometastasis patients with or without postoperative radiotherapy was comparable, even in patients with inferior WPOI. Radiotherapy, however, may only benefit patients with IV/V levels of micrometastasis. These data indicated that postoperative radiotherapy is dispensable for only micrometastasis OSCC patients.

Abstract
Objective: To investigate the association between maternal body height and risk of preterm birth. Methods: A total of 11 311 pregnant women who gave birth of live singletons were recruited from the Healthy Baby Cohort Study in Hubei province, China from September 2012 to October 2014. Finally 11 070 pregnant women were selected as study subjects. Data were collected by using questionnaires, their prenatal care records and medical records. The women were divided into 4 groups according to the quartiles distribution (<158 cm, 158- cm, 160- cm, and >164 cm). Gestational age was estimated according to maternal last menstrual time. Preterm birth was defined as delivering a live singleton infant at 28-37 weeks' gestational age. Logistic regression was used to calculate the odds ratios (OR) and 95% confidence intervals (CI) for the association between body height and preterm birth. Results: Among the 11 070 pregnant women, the incidence of preterm birth was 5.9%. Logistic regression analysis indicated that women in group with body height <158 cm had 46% (OR=1.46, 95%CI: 1.16-1.83) higher risk of giving preterm birth than those in group with body height >164 cm after adjustment for potential confounders. Every 1- cm increase in body height was associated with 3% lower risk of preterm birth (OR=0.97, 95%CI: 0.95-0.99). Conclusion: Shorter body height was a risk factor for preterm birth. It is necessary to strengthen the monitoring in pregnant women with short body height to reduce the risk of preterm birth.

Abstract
We report a case of giant gastrointestinal stromal tumour of the stomach in a 71-year-old woman, with emphasis on its going through surgical resection. The physical examination and radiological findings revealed that a giant mass occupied most of the abdominal cavity. The patient underwent an en-block resection of the mass, partial resection of the distal stomach and Billroth II gastrojejunostomy. The pathological diagnosis was gastrointestinal stromal tumour. The patient had a long-term disease-free survival. We emphasise that complete surgical resection is the only effective radical treatment approach for giant gastrointestinal stroma of the stomach. In some cases, we still have the opportunity for resection of these tumours because of their expansive growth, even though the lesions are very large.

Abstract
Take-all is a severe root disease of wheat worldwide that is caused by the soilborne fungal pathogen Gaeumannomyces graminis var. tritici (Ggt). In this study, 272 Bacillus isolates were screened for their antifungal activity in vitro to Ggt. Of the 128 strains that demonstrated an antagonistic action, 24 of these exhibited at least three of the four plant growth promotion parameters (i.e. indole acetic acid and siderophore production, inorganic phosphorus solubilization and organic phosphorus solubilization) that were tested in wheat plants. The most effective strain found was Bacillus subtilis Pnf-12; its disease reduction effect reached 69%. Pnf-12 also caused a significant improvement (P < 0·05) in the root and shoot weights of wheat plants, though their root length and shoot height were similar to the noninoculated treatment (P > 0·05). The mechanism for this disease control may be linked to the production of the antifungal lipopeptides surfactin, iturin and fengycin production, all of which were detected in the cell-free supernatant of Pnf-12. SIGNIFICANCE AND IMPACT OF THE STUDY Take-all, which is caused by the soilborne fungal pathogen Gaeumannomyces graminis var. tritici (Ggt), is one of the most widespread and devastating root diseases of wheat plants. This study focuses on a novel screening strategy of Bacillus isolates to evaluate their potential biological control capacity for suppressing wheat take-all. The joint assessment of antifungal activities, growth promotion factors and variety of antibiotic synthesis genes, in addition to greenhouse experiments, allowed for the identification and demonstration of the Bacillus isolate Pnf-12 as an effective disease control agent.

Abstract
Objective: To explore the differences of one year death and stroke recurrence between ischemic stroke patients with intracranial atherosclerotic stenosis or occlusion of anterior circulation and those of posterior circulation. Methods: All the patients were from the Chinese Intracranial Atherosclerosis Study (CICAS), between October 2007 and June 2009; patients with extracranial stenosis or occlusion, patients without acute infarction by diffusion weighted image, and patients with intracranial atherosclerosis of both anterior and posterior circulation were excluded.All the enrolled patients were divided into three groups: no significant intracranial atherosclerosis group (n=964), anterior circulation intracranial atherosclerosis group (n=440), posterior circulation intracranial atherosclerosis group (n=233). One year outcome was evaluated by any cause of death and stroke recurrence. Results: Of the 1 637 patients, 30 cases were died and 58 cases had stroke recurrence within one year.Compared with : no significant intracranial atherosclerosis group, adjusted hazard ratio (95% confidence interval) of one-year death for anterior and posterior circulation intracranial atherosclerosis group were 1.349 (0.311-5.851), 4.542 (1.227-16.813), respectively.Adjusted hazard ratio (95% confidence interval) of one year stroke recurrence were 1.663 (0.620-4.460) and 2.464 (0.935-6.493), respectively. Conclusions: Ischemic stroke patients with intracranial atherosclerosis of posterior circulation has higher risk of one year death. One year stroke recurrence risk for patients with intracranial atherosclerosis of anterior and posterior circulation needs to be further evaluated.

Abstract
Objective: To analyze the clinical manifestations, therapeutic efficacy, prognosis and characteristics of NPC1 mutation in Chinese patients with Niemann-Pick disease type C(NPC). Methods: Ten unrelated Chinese NPC patients were diagnosed by NPC1 mutation analysis from July 2013 to February 2017 in Beijing Tian Tan Hospital of Capital Medical University. Clinical data of 10 cases were analyzed retrospectively which included clinical manifestations, laboratory results and NPC1 gene mutation features, and a series of follow-up were carried out about therapeutic efficacy and prognosis. Results: Ten patients suffering from NPC included 5 males and 5 females, aged from 42 days to 14 years when they presented to Tian Tan Hospital. According to their age of neurological onset, 4 were in early infantile period, 2 in late infantile period, 2 in juvenile periods, and the other 2 cases in neonatal period. They all presented with splenomegaly, 5 of 10 accompanied with hepatomegaly. Two cases of neonatal subtype presented mainly with delayed neonatal cholestatic jaundice and hepatosplenomegaly, accompanied with decreased muscle tone and slight psychomotor retardation. The other 8 cases presented with severe neurological involvement, such as progressive encephalopathy, ataxia and language impairment, 4 with dystonia, 3 with decreased muscle tension, 5 with vertical supranuclear gaze palsy, 5 with gelastic cataplexy, and 4 with epilepsy. Eight of 9 cases presented with foam cells in their bone marrow. Head MRI showed diffuse cerebral atrophy in 8 cases, thin corpus callosum in 2 cases, and brain white matter abnormal signals in 2 cases. Among 10 cases, 18 different mutations of NPC1 allelic genes were identified including 11 reported mutations, 3 novel missense mutations: c. 3683T>C (p.Met1128Thr), c.1926G>C (p.Met642Iie) and c. 3006C>G (p.Phe1002Leu), 2 novel nonsense mutation: c. 1142G>A(p.Trp381Ter ) and c. 3229C>T(p.Arg1077Ter), 1 novel minimal deletion mutation: c. 1385-1386del, and 1 novel intron mutation: c. 1757+ 5G>A. In 5 cases, the symptom of gelastic cataplexy was alleviated by imipramine, and the convulsion was relieved by valproate in 2 cases, by carbamazepine in 1 case at the beginning of seizure. During the 25 (3-66) months of follow-up, 4 cases died, the others' neurological symptoms were deteriorated progressively. Conclusions: The NPC1 gene mutation were high heterozygous in this group, and 7 novel mutations enriched the gene mutation spectrum of NPC1. The neurological manifestations were complicated in patients with NPC, and the symptomatology would be different according to their onset age of neurological symptoms. There might be effective symptomatic treatment for gelastic cataplexy by imipramine and for convulsion by valproate or carbamazepine.

Abstract
To determine if plasma exchange combined with plasma perfusion is a reliable and effective temporary liver support treatment for patients on the waiting list for OLT, we tested this method in 5 patients with end-stage and 3 patients with middle-stage severe hepatitis. Four patients were successfully controlled until a donor liver was available 4 to 13 days later. In contrast, the remaining 4 patients were not adequately controlled by this treatment and experienced aggravated disease progression, dying 3 to 8 days after treatment while still awaiting OLT. Of those 4 patients who received OLT, 2 patients died from multi-organ failure caused by hepatic failure, while the other 2 survived. These findings show that plasma exchange combined with plasma perfusion provides temporary support for some patients on the waiting list for OLT. The ability of patients to successfully bridge to OLT is closely associated with the degree of liver failure, complications, multi-organ failure, and the length of the waiting period for a donor liver.

Abstract
Engineering of novel functional nanocomposite as like as the metallic nanocrystals supported non-stoichiometric perovskite nanomaterial in controlled parameters (size, shape and ratio of chemical characteristics) is a challengeable task. In this context, we present a facile route to fabricate and study its physicochemical property at real time mode in this report. Nanoscale pure Pb crystals surfaced on non-stoichiometric A-site deficient Pb1-xTiO3-y nanoparticle were fabricated when a precursor lead titanate (PbTiO3) nanoparticle was exposed to an electron beam irradiation (EBI) in a transmission electron microscope (TEM) at ambient temperature. In the state of the art, the chemical states and electronic structure of non-irradiated and irradiated PbTiO3 were studied by X-ray photoelectron spectroscopy (XPS). Electron bombardment resulted in a new visible feature at low binding energy in the Pb 4f core level, while Ti 2p and O 1s line shape showed slight changes. The Fermi level of the corresponding materials was determined to be 1.65 ± 0.1 eV and 2.05 ± 0.1 eV above the valence band maximum, respectively. The normal, weakly p-type PTO exhibits peculiar n-type feature after EBI process (The Fermi level moves near to the conduction band). A feasible mechanism is proposed involving the electron-stimulated local bond-breaking phenomenon in PbTiO3.
