Abstract
Abstract
Background:Neurofibromin is a key tumor suppressor, well-known as a GTPase-Activating-Protein (GAP) to attenuate Ras signaling. It is encoded by the NF1gene, so named because its inactivation was first discovered to cause Neurofibromatosis type 1, an autosomal dominant genetic disorder. We have recently reported thatnonsense (NS) and frameshift (FS) mutations, but not missense mutations, in NF1are associated with a markedly higher risk of relapse and death in early stage ER+breast cancer after adjuvant tamoxifen monotherapy (Griffith et al. in press). Surprisingly, despite being best known as a GAP, no missense mutations inactivating NF1's GAP activity were found in our cohort. We have evidence that these NF1NS/FS mutations cause the resulting mRNAs to be degraded, leading to depletion of the entire NF1 protein. In a separate study that was presented here last year, we showed that NF1 is also an ER co-repressor, which partially explains why the loss of the single tumor suppressor NF1 is so detrimental — because this turns on two potent oncogenic pathways. Thus far there is no effective means to assess loss of NF1 protein in cancer. The objective of this project is to identify these aggressive NF1-negative breast cancers by establishing an immunohistochemistry (IHC) protocol with a valid NF1 antibody in order to properly find and treat them in the future.
Methods:A monoclonal antibody was raised against the C-terminus of NF1. Immunostaining as well as IHC was performed using a set of breast cancer cell lines with varying degrees of NF1 protein levels, including several NF1 null-like cell lines as negative controls. To assess whether the IHC protocol can be used on patients, NF1+and NF1–PDXs as well as patient biopsies were examined.
Results: We have purified a monoclonal antibody against NF1 (m376). By immunostaining, a strong NF1 signal can be seen in T47D cells, which have four copies of the NF1gene. In contrast, there was barely any signal in MDA-MB-175VII cells, which lack detectable NF1 due to NF1FS mutations. While NF1 appears mostly cytoplasmic, 10-15% can be seen in the nucleus. Nuclear NF1 levels can be further increased by the nuclear export blocker leptomycin-B, suggesting that NF1 is shuttled in and out of the nucleus. IHC staining confirmed these features of NF1. In addition, a weak nuclear signal can be seen in cancer cells carrying NF1FS mutations. Experiments are on-going to assess how to analyze tumor samples for NF1 loss and whether NF1FS mutations cause expression of truncated proteins that are nuclear.
Conclusion: Our results suggest that the m376 antibody has the potential to be used for IHC, provided that samples known to be NF1+or NF1–are included as controls. The success of this project will have particular clinical impact in telling us who should notbe treated by tamoxifen. Furthermore, we have an approved clinical trial protocol to assess the concept that these NF1–patients should instead be treated by combining a Ras pathway inhibitor and a SERD.

Abstract
Objective: To summarize the clinical manifestations and gene variations of combined immunodeficiency caused by ORAI1 variation with a case report and literature review. Methods: The clinical data of the patient who was diagnosed with ORAI1 variation caused combined immunodeficiency in the Department of Pediatrics in Xiangya Hospital of Central South University in February 2018 were extracted and analyzed. The literature till August 2018 was searched with key words of 'ORAI1', and 'immunodeficiency' in both English and Chinese in the database of China national knowledge infrast ructure (CNKI), Wanfang and Pubmed. Results: The patient was a 15 months old girl with acute onset of bilateral ptosis after upper respiratory tract infection, which was rapidly progressed to systemic myasthenia and accompanied with recurrent respiratory tract infection during the treatment. The patient poorly to responded immunomodulatory therapy and anti-infection therapy. Laboratory tests demonstrated decreased complement C3 and NK cell (CD3(-)CD56(+)), increased anti-thyroglobulin, thyroid peroxidase antibody and B lymphocyte (CD3(-)CD19(+)), and slightly increased anti-acetylcholine receptor antibody. Genetic analysis showed the homozygous variation of ORAI1 gene exon l c.12 G>T (p.E4D), with heterozygostty of both parents. There were only 4 papers reporting this disease in the literature review. A total of 7 patients with ORAI1 gene variation were reported, including 3 homozygous variations, 2 heterozygous variations and 2 complex heterozygous variations. The clinical manifestations included early onset recurrent infection, congenital hypotonia, elevated serum IgA and IgM, decreased NK cells, and family history of hereditary diseases. Four of the 7 reported cases died of pulmonary infection and sepsis, and the other 3 survived with low muscular tone and poor self-care ability. Conclusions: The most common clinical manifestations of ORAI1 variation caused combined immunodeficiency are recurrent infection and congenital hypotonia. Myasthenia induced recurrent respiratory tract infection is an important factor of poor prognosis in severe patients. There is a lack of effective treatment for this disease, and the prognosis is poor.

Abstract
BACKGROUND Cryopreservation of hematopoietic stem cells (HSCs) has widely been used in stem cell transplantation and cellular therapy treating various human diseases. However, the current conventional cooling approach for the cryopreservation of HSCs has the following potential problems: (1) requirement of a very expensive computer-programmed liquid nitrogen freezer (LNF) for the cooling rate control, (2) a large consumption of liquid nitrogen, (3) periodic breakdown of the LNF due to the mechanical failure of the liquid nitrogen valves (i.e., magnetic-solenoid valves) inside the LNF, and (4) constant monitoring of the LNF operation during the HSCs cooling process. OBJECTIVE To test and evaluate a simple and reliable approach for the cryopreservation of HSCs using the passive cooling technique. MATERIALS AND METHODS A passive cooling-rate-controlled device (PCD) was developed and used to cryopreserve HSCs. The PCD is inexpensive, simple, and user-friendly, which needs only the minimum maintenance and no consumption of liquid nitrogen. The PCD was compared to the LNF for the cryopreservation of HSCs in the present study through experiments. The cell viability and functionality were evaluated after cryopreservation. RESULTS In comparison with the LNF method, the PCD approach enabled high cell viability/survival, recovery rate, and functionality after cryopreservation processes. CONCLUSION The PCD offers a cost-effective, simple, and reliable approach for the optimal cryopreservation of HSCs.

Abstract
Objectives The incidence of acute Achilles tendon rupture appears to be increasing. The aim of this study was to summarize various therapies for acute Achilles tendon rupture and discuss their relative merits. Methods A PubMed search about the management of acute Achilles tendon rupture was performed. The search was open for original manuscripts and review papers limited to publication from January 2006 to July 2017. A total of 489 papers were identified initially and finally 323 articles were suitable for this review. Results The treatments of acute Achilles tendon rupture include operative and nonoperative treatments. Operative treatments mainly consist of open repair, percutaneous repair, mini-open repair, and augmentative repair. Traditional open repair has lower re-rupture rates with higher risks of complications. Percutaneous repair and mini-open repair show similar re-rupture rates but lower overall complication rates when compared with open repair. Percutaneous repair requires vigilance against nerve damage. Functional rehabilitation combining protected weight-bearing and early controlled motion can effectively reduce re-rupture rates with satisfactory outcomes. Biological adjuncts help accelerating tendon healing by adhering rupture ends or releasing highly complex pools of signalling factors. Conclusion The optimum treatment for complete rupture remains controversial. Both mini-open repair and functional protocols are attractive alternatives, while biotherapy is a potential future development. Cite this article: X. Yang, H. Meng, Q. Quan, J. Peng, S. Lu, A. Wang.

Abstract
Objective: To report a family diagnosed with Allan-Herndon-Dudley syndrome (AHDS) due to SLC16A2 gene mutation and to summarize the phenotypes, genotypes, diagnosis, treatment, and prognosis. Methods: The clinical features of a family of AHDS diagnosed in Xiangya Hospital of Central South University in November 2017 were analyzed. Related literature was searched at Online Mendelian Inheritance in Man (OMIM), PubMed, CNKI and Wanfang database (from the establishment of databases to June 2018) by using "Allan-Herndon-Dudley syndrome" , and "AHDS" as keywords and the case reports from April 2013 to June 2018 were reviewed. Results: The proband was a boy aged 8 months who presented with global developmental retardation, inability to hold up the head, disability to sit independently or grab, no language development, elongated face, big ears, esotropia, scoliosis, hypotonia in the trunk, hypertonia in extremities, and hyperreflexia. Brain magnetic resonance imaging (MRI) showed widening of the extracerebral space and delayed myelination. Thyroid function tests revealed increased FT3, decreased FT4 and normal TSH. Whole exome sequencing (WES) revealed the SLC16A2 gene c.431-1 (IVS1) G>C hemizygous mutation. The infant's mother and grandmother are carriers, but whose father had no related mutation. One uncle from maternal side had severe psychomotor retardation as well as dystonia and died at one year of age with unknown etiology. A total of 97 articles were retrieved in which 19 case reports were reviewed. Forty-two cases (22 from 8 families and 20 sporadic) were reported. Among these 42 cases (all males), all of them presented with moderate to severe cognitive dysfunction, 15 with seizures; 36 were bedridden, only 4 could walk; 31 had no language development, 2 could speak sentences, 4 could speak few words, 1 had babbling sounds. Furthermore,16 had microcephaly, 18 had facial dysmorphism, 6 had esotropia, 2 had hearing loss,14 had scoliosis, 11 had joint contracture, 30 had low body weight/muscle wasting, 37 had hypotonia in trunk or extremities, 32 had progressive spastic paraplegia or hypertonia. In terms of thyroid function, 33 had abnormal results, within whom 30 had increased T3, 25 had decreased T4 and 3 had increased TSH. Brain MRI showed delayed myelination in 22 cases, within which one normalized with development. Genetic tests showed that 31 had missense mutation (14 sporadic), 5 had deletion mutation (3 sporadic, and 1 due to frameshift mutation), 5 had insertion mutation (2 sporadic), and 1 had repeated mutation. The prognosis was poor as patients often died of recurrent respiratory tract infection. Conclusions: The main clinical manifestations of AHDS are severe global developmental retardation, hypotonia, spastic paraplegia, abnormal serum levels of thyroid hormone and delayed brain myelination. SLC16A2 c. 431-1 (IVS1) G > C mutation is accountable for this disease.

Abstract
Less attention has been focused on the industrial applications of levan-type fructan than that of inulin. Levan-type fructan is a unique homopolysaccharide consisting of fructose residues with a β-(2, 6) linkage that possesses unique physiochemical properties such as low intrinsic viscosity. In this study, the recombinant levansucrase from Erwinia amylovora was used to efficiently produce levan from sucrose, and under optimised conditions, 195 g/L levan was produced from 500 g/L sucrose, with the highest conversion rate of 59%. The physicochemical properties of E. amylovora levan, such as surface morphology, thermal behaviour, rheology behaviour and texture analysis, were evaluated and compared with those of commercial gels, including xanthan, guar, carrageenan and Arabic gums. The produced E. amylovora levan showed a series of acceptable physicochemical properties, indicating a potential application for levan as a novel water-soluble micro gel. The conclusions of this study support the exploration of the use of more hydrogels in the food, medicinal and cosmetic industries.

Abstract
Dengue is the most prevalent and rapidly spreading mosquito-borne viral disease. As a dengue non-endemic country, China has experienced several dengue outbreaks in recent years. However, dengue patients in China displayed distinct clinical characteristics compared to patients in endemic countries. To standardize the diagnosis and treatment of dengue fever, the experts of the Society of Infectious Diseases, Society of Tropical Medicine and Parasitology of Chinese Medical Association, and the Society of Emergency Medicine, China Association of Chinese Medicine have reached this guideline based on guidelines for diagnosis, treatment, prevention and control of dengue (World Health Organization, 2009); guidelines for diagnosis and treatment of dengue (National Health and Family Planning Commission of the People's Republic of China, 2014, Edition 2), health industry standard of the People's Republic of China "diagnosis for dengue fever (WS216-2018)" and systemic reports on dengue. The guideline includes 8 aspects: introduction, terminology, epidemiology and prevention, etiology and pathogenesis, clinical features, diagnosis, treatment and problems to be solved.

Abstract
Amino acids play a key role in regulating milk protein synthesis partly through activation of the mammalian target of rapamycin (mTOR) signaling pathway. However, the involvement of extracellular AA sensing receptors in this process is not well understood. In nonruminants, it is well established that the AA taste 1 receptor member 1/3 (TAS1R1/TAS1R3) heterodimer contributes to the sensing of most l-AA. Whether this receptor is functional in bovine mammary cells is unknown. The objective of this study was to determine essential AA signaling through TAS1R1/TAS1R3 and their roles in regulating mTOR signaling pathway and casein mRNA abundance in primary bovine mammary epithelial cells and the Mac-T cell line. The bovine mammary epithelial cells were stimulated with complete Dulbecco's modified Eagle's medium (+EAA), medium without EAA (-EAA), or medium supplemented with only 1 of the 10 essential AA, respectively. The nonessential AA levels were the same across all treatments. Small interference RNA targeting TAS1R1 were designed and transfected into bovine primary mammary epithelial cells (bPMEC). Supplementation of a complete mixture of essential AA or Arg, Val, Leu, His, Phe, Met, and Ile individually led to greater mTOR phosphorylation. Phosphorylation of ribosomal protein S6 kinase β-1 was greater in the presence of Val, Leu, Trp, Met, and Ile. Valine, Leu, Met, and Ile led to greater eIF4E-binding protein 1 phosphorylation. Although +EAA and a few individual AA tested induced increases in intracellular calcium, Met and Val were the most potent. Knockdown of TAS1R1 decreased intracellular calcium in bPMEC cultured with both Val and Met. Phosphorylation of mTOR, ribosomal protein S6 kinase β-1, and eIF4E-binding protein 1 was lower when TAS1R1 was knocked-down in bPMEC supplemented with Val and Met. In addition, small interference RNA silencing of TAS1R1 resulted in lower β-casein (CSN2) abundance. The TAS1R1/TAS1R3 receptor may sense extracellular AA and activate mTOR signaling in bovine mammary cells, likely by elevating intracellular calcium concentration. This mechanism appears to have a role in Met- and Val-induced changes in CSN2 mRNA abundance. Further in vivo studies will have to be performed to assess the relevance of this mechanism in the mammary gland.

Abstract
OBJECTIVE As a novel and promising seed cell, human umbilical cord Wharton's jelly mesenchymal stem cells (hWJMSCs) are widely applied in tissue engineering. However, whether hWJMSCs can better repair and regenerate the articular cartilage in big animals than microfracture (MF, a predominant clinical treatment strategy for damaged cartilage) is unclear. Evaluation of the validity, and safety of hWJMSCs in a caprine model with a full-thickness femoral condyle articular cartilage defect, compared with MF is required. METHODS After cultivation and identification, hWJMSCs were seeded in an acellular cartilage extracellular matrix (ACECM)-oriented scaffold to construct cell-scaffold complex. Six goats with full-thickness femoral condyle articular cartilage defects were randomized to MF (microfracture group, MFG) and cell-scaffold complexes (experimental group, EG). At 2 and 4 weeks, joint fluid was used to assess immuno-inflammatory responses. At 6 and 9 months, all goats were euthanized for assessment of morphology, and magnetic resonance imaging (MRI), histology staining, and evaluation of the elasticity modulus and glycosaminoglycan (GAG) contents of the repaired regions. RESULTS There were no significant differences between the two groups in immuno-inflammatory parameters. MRI demonstrated higher-quality cartilage and complete subchondral bone at defect sites in the EG at 9 months. Histological staining showed that extracellular cartilage, cartilage lacuna and collagen type II levels were higher in the EG compared to the MFG, while the EG exhibited a higher elasticity modulus. CONCLUSIONS The hWJMSCs-ACECM scaffold complex achieved better quality repair and regeneration of hyaline cartilage without cartilage-inducing factor, while retaining the structure and functional integrity of the subchondral bone, compared with MF.

Abstract
This study investigated the factors affecting the semen traits of boars in Southern China. A total of 172,408 ejaculates of boars from 9 AI centers were collected from January 2013 to May 2016. A linear growth model was used to analyze the effects of leve1 1 (boar breed, age, season, and boar age at herd entry) and level 2 (housing type) factors on semen quality. The intraclass correlation coefficients of semen volume, total sperm number, functional sperm number, sperm concentration, motility, and abnormal sperm were 0.62, 0.62, 0.61, 0.60, 0.54, and 0.70, respectively. Boars reared in ordinary houses had lower total and functional sperm numbers than those reared in air filtration houses ( < 0.05). The functional sperm number of Duroc boars was lower than that of Landrace and Yorkshire boars ( < 0.05). The total and functional sperm numbers were lowest from May to September and peaked at the age of 34.1 and 37.7 mo, respectively. Furthermore, boars aged 8 and 9 mo at herd entry had greater functional sperm numbers than those aged 5, 6, 7, and 12 mo at herd entry ( < 0.05), whereas no significant difference was observed between boars aged 8 mo and boars aged 9 mo at herd entry ( > 0.05). In conclusion, the linear growth model is suitable for longitudinal data analysis. To improve boar breeding, sunstroke prevention in the early spring should be given greater attention. Importantly, 8 mo appears to be the most suitable age for boar introduction, especially for Duroc boars.

Abstract
Bilayer ruthenate Ca3(Ru1-x Fe x )2O7 (x = 0.05) exhibits an incommensurate magnetic soliton lattice driven by the Dzyaloshinskii-Moriya interaction. Here we report complex field-induced magnetic phase transitions and memory effect in this system via single-crystal neutron diffraction and magnetotransport measurements. We observe first-order incommensurate-to-commensurate magnetic transitions upon applying the magnetic field both along and perpendicular to the propagation axis of the incommensurate spin structure. Furthermore, we find that the metastable states formed upon decreasing the magnetic field depend on the temperature and the applied field orientation. We suggest that the observed field-induced metastability may be ascribable to the quenched kinetics at low temperature.

Abstract
AIM This study aimed to investigate alterations in HbA1c , glycated albumin (GA) and 1,5-anhydroglucitol (1,5-AG) in Chinese first-degree relatives of individuals with diabetes (FDR) in pursuit of an index for early screening of glucose metabolism disturbance. METHODS A total of 467 participants (age range: 20-78 years) with normal weight and normal glucose tolerance, as determined by a 75-g oral glucose tolerance test, were enrolled. HbA1c was measured using high-performance liquid chromatography. Serum GA and 1,5-AG levels were determined by enzymatic methods. Serum insulin levels were measured using an electrochemiluminescence immunoassay. RESULTS The study population included 208 FDR and 259 non-FDR. Serum 1,5-AG levels were lower in FDR than that in non-FDR (20.4 ± 7.5 vs 23.8 ± 8.3 μg/ml, P < 0.001), but HbA1c and GA levels did not differ between them (P = 0.835 and 0.469, respectively). Logistic regression analysis revealed an independent relationship between a first-degree family history of diabetes and reduced serum 1,5-AG levels (odds ratio = 0.944, P < 0.001). Multiple regression analysis showed that a first-degree family history of diabetes (β = -3.041, P < 0.001) and insulinogenic index (β = 0.081, P = 0.001) were independently associated with serum 1,5-AG levels. CONCLUSION In a Chinese population with normal glucose tolerance, serum 1,5-AG levels were lower among FDR, and serum 1,5-AG levels were independently associated with FDR status. For FDR, serum 1,5-AG levels were more sensitive than HbA1c or GA levels to early-phase abnormality in glucose metabolism.

Abstract
Chinese indigenous pigs in Zhejiang Province are well known for their high fecundity. In order to verify breed subdivision at the genomic level, we investigated genetic diversity and population structure of seven breeds and made comparisons with three Western pig breeds using next-generation sequencing data. Parameters obtained from allelic richness and proportion of polymorphic markers indicated that the genetic diversity of the Chinese indigenous pigs was higher than that of the Western pigs, with the highest and lowest values found in the Chaluand and the Landrace pigs respectively. Both neighbor-joining tree and principal components analysis could distinguish breeds from one another and structure analysis showed less differentiation among Western pigs than among the Chinese pigs. The average linkage disequilibrium decay over distance was significantly less in the Chinese pigs compared with the Western pigs, ranging from 188.2 to 280.6 kb for the Chinese pigs and 680.3 to 752.8 kb for the Western breeds and showing an average r2 threshold value of 0.3. Results obtained from high-density SNP comparison over the whole genome on genetic diversity and population structure were in agreement with the current breed classification of the pigs in Zhejiang Province. More importantly, the results presented here advances our current understanding of the genomic biology of Chinese indigenous pigs in Zhejiang Province and allows for implementation of conservation strategies in additional breeds.

Abstract
Objective: To investigate the efficacy and safety of the new investigational drug pegylated interferon α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 µg/week) combined with ribavirin in the treatment of patients with genotype 1/6 chronic hepatitis C (CHC), with standard-dose Peg-IFN-α-2a combined with ribavirin as a positive control. Methods: A multicenter, randomized, open-label, and positive-controlled phase III clinical trial was performed. Eligible patients with genotype 1/6 CHC were screened out and randomly divided into Peg-IFN-α-2b(Y shape, 40kD) group and Peg-IFN-α-2a group at a ratio of 2:1. The patients in both groups were given oral ribavirin for 48 weeks in addition and then followed up for 24 weeks after drug withdrawal. Abbott Real Time HCV Genotype II was used to determine HCV genotype, and Cobas TaqMan quantitative real-time PCR was used to measure HCV RNA level at 0, 4, 12, 24, 48, and 72 weeks. Adverse events were recorded in detail. The primary efficacy endpoint was sustained virological response (SVR), and a non-inferiority test was also performed. Results: A total of 561 patients with genotype 1/6 CHC were enrolled, among whom 529 received treatment; 90.9% of these patients had genotype 1 CHC. The data of the full analysis set showed that SVR rate was 69.80% (95% CI 65.00%-74.60%) in the trial group and 74.16% (95% CI 67.73%-80.59%) in the control group (P = 0.297 0). The data of the per protocol set (PPS) showed that SVR rate was 80.63% (95% CI 76.04%-85.23%) in the trial group and 81.33% (95% CI 75.10%-87.57%) in the control group (P = 0.849 8), and the 95% CI of rate difference conformed to the non-inferiority standard. The analysis of the PPS population showed that of all subjects, 47.9% achieved rapid virologic response, with a positive predictive value of 93.8%. The incidence rate of adverse events was 96.30% in the trial group and 94.94% in the control group, and the incidence rate of serious adverse events was 5.13% in the trail group and 5.06% in the control group. Conclusion: In the regimen of Peg-IFN-α combined with ribavirin for the treatment of genotype 1/6 CHC, the new investigational drug Peg-IFN-α-2b(Y shape, 40 kD) has comparable clinical effect and safety to the control drug Peg-IFN-α-2a.

Abstract
Essentials M1/M2 imbalance is involved in many autoimmune diseases, and could be restored. The expressions and functions of M1 and M2 were investigated in an in vitro culture system. A preferred M1 polarization is involved in the pathogenesis of immune thrombocytopenia (ITP). High-dose dexamethasone or all-trans-retinoic acid restores M1/M2 balance in ITP patients. SUMMARY Background Immune thrombocytopenia (ITP) is an autoimmune disorder. Deficiency of immune tolerance in antigen-presenting cells and cross-communication between antigen-presenting cells and T cells are involved in the pathogenesis of ITP. Macrophages can polarize into proinflammatory M1 or anti-inflammatory M2 phenotypes in response to different environmental stimuli, and have diverse immunologic functions. Objectives To investigate the M1/M2 imbalance in ITP and whether high-dose dexamethasone (HD-DXM) or all-trans-retinoic acid (ATRA) could restore this imbalance. Methods The numbers of M1 and M2 macrophages in the spleens of ITP patients and patients with traumatic spleen rupture were analyzed by immunofluorescence. Monocyte-derived macrophages were cultured and induced with cytokines and drugs. The expression of M1 and M2 markers and functions of M1 and M2 macrophages before and after modulation by HD-DXM or ATRA were evaluated with flow cytometry and ELISA. Results There was preferred M1 polarization in ITP spleens as compared with healthy controls. Monocyte-derived macrophages from ITP patients had increased expression of M1 markers and impaired immunosuppressive functions. Either HD-DXM or ATRA corrected this imbalance by decreasing the expression of M1 markers and increasing the expression of M2 markers. Moreover, HD-DXM-modulated or ATRA-modulated macrophages suppressed both CD4+ and CD8+ T-cell proliferation and expanded CD4+ CD49+ LAG3+ type 1 T-regulatory cells. HD-DXM or ATRA modulated macrophages to shift the T-cell cytokine profile towards Th2. Treating patients with HD-DXM or ATRA revealed that macrophages induced from responders showed a predominant M2-like phenotype and immunosuppressive function. Conclusions Aberrant macrophage polarization is involved in the pathogenesis of ITP. Either HD-DXM or ATRA is able to correct this imbalance.

Abstract
Abnormal expression of activating/inhibitory receptors leads to natural killer (NK) cells dysfunction in tumor. Here we show that programmed cell death protein 1 (PD-1), a well-known immune checkpoint of T cells, is highly expressed on peripheral and tumor-infiltrating NK cells from patients with digestive cancers including esophageal, liver, colorectal, gastric and biliary cancer. The increased PD-1 expression on NK cells indicates poorer survival in esophageal and liver cancers. Blocking PD-1/PD-L1 signaling markedly enhances cytokines production and degranulation and suppresses apoptosis of NK cells in vitro. PD-1/PD-L1 exerts inhibitory effect through repressing the activation of PI3K/AKT signaling in NK cells. More importantly, a PD-1 blocking antibody was found to significantly suppress the growth of xenografts in nude mice, and this inhibition of tumor growth was completely abrogated by NK depletion. These findings strongly suggested that PD-1 is an inhibitory regulator of NK cells in digestive cancers. PD-1 blockade might be an efficient strategy in NK cell-based tumor immunotherapy.

Abstract
BACKGROUND Symmetrical acrokeratoderma (SAK) is characterized by brown to black hyperkeratotic patches on acral regions. Although epidermal hyperkeratosis and acanthosis are consistent pathological changes, the nature of epidermal hyperplasia is unknown. AIM To evaluate epidermal proliferation and differentiation and melanocytic density in skin lesions of SAK. METHODS Expression of keratin 10 (K10), K14, K16, involucrin, filaggrin, Ki-67, and Melan-A was detected by immunohistochemistry in eight patients with SAK, seven patients with ichthyosis vulgaris (IV) and six healthy controls (HCs). RESULTS Expression of K14, K16, involucrin and filaggrin was upregulated in patients with SAK compared with patients with IV and the HCs (P < 0.01-0.05), but K10 expression was similar for the three groups (P > 0.05). Numbers of Ki-67+ and Melan-A+ cells were higher in patients with SAK than in patients with IV and the HCs (P < 0.05). CONCLUSIONS These results demonstrate that excessive keratinocyte proliferation and abnormal differentiation contribute to epidermal hyperplasia, while melanocytic proliferation is responsible for the pigmented lesions in SAK.

Abstract
Objective: To analyze the clinical and gene mutation characteristics of dynamin-1 (DNM1)-related infantile spasms. Method: Clinical, laboratory and genetic data of one case of DNM1-related infantile spasms diagnosed by Xiangya Hospital in September 2015 were analyzed.Through taking "Dynamin-1" "DNM1" as key words to search at CNKI, Wanfang, PubMed and OMIM to date (April 2016), the clinical characteristics of 9 reported cases of DNM1-related epileptic encephalopathy in international literature with our case were reviewed. Result: The boy is the second child of healthy and nonconsanguineous parents.At 7 months, he started to have seizures with head dropping, and he was brought for the first time to our hospital at the age of 17 months.The patient presented with severe psychomotor retardation, epilepsy, muscular hypotonia, and electroencephalography showed hypsarhythmia.He received 28 days of adrenocorticotropic hormone (ACTH) therapy.After that, his seizures were improved with valproic acid and levetiracetam, and disappeared between 3 years and 5 months to 5 years and 5 months of age on treatment with valproic acid only.Exome-sequencing study (trios) identified novel heterozygous mutation c. 443A>G (p.Glu148Arg) in DNM1. Up to now, 9 cases of epileptic encephalopathy (infantile spasms or Lennox-Gastaut syndrome) associated with de novo DNM1 gene mutations have been reported. Conclusion: The main clinical features of DNM1 mutations include intractable seizures, intellectual disability, developmental delay, hypotonia, and developmental delay before the onset of seizures.
