Abstract
Derived from Zhang Zhongjing's Shang han za bing lun (Treatise on Cold Pathogenic and Miscellaneous Diseases)of the Han Dynasty, Lingguizhugan Decoction was composed of 4 Chinese herbs: Poria, Ramulus Cinnamomi, Rhizoma Atractylodis Macrocephalae, and Radix et Rhizoma Glycyrrhizae, for treating fullness and discomfort in chest and hypochondrium, phlegm and fluid retention, dizziness etc. The relevant descriptions and records in ancient Chinese medical works were collected, and as a result, altogether 162 items from 106 kinds of ancient book were available. Through statistical analysis, it was found that most of them followed the original records of composition, dosage and indications in Zhang's original work, only with some extensions in the scope of its clinical application.

Abstract
Various studies have investigated laryngeal function and survival after induction chemotherapy in hypopharyngeal carcinoma, but potential factors to help predict response rates after induction chemotherapy remain unknown. This retro- spective study evaluated which factors are related to an ineffective response to two-cycle docetaxel, cisplatin, and 5-fluoro- uracil (TPF) induction chemotherapy in hypopharyngeal carcinoma to determine potential candidates for this treatment in clinical practice. From Jan 2005 to Dec 2015, 81 patients diagnosed with hypopharyngeal squamous cell carcinoma based on a pathological examination were analyzed. They were administered two-cycle TPF induction chemotherapy, and magnetic resonance imaging was performed before and after induction chemotherapy. The mean survival time was 5.7 years (95% confidence interval, 5.1-6.2 years). The 1, 3, 5 and 6-year survival rates were 98.8%, 80.1%, 64.5%, and 54.2%, respectively. TPF induction chemotherapy was well tolerated; the main adverse effects resolved with symptomatic treatment. A response to TPF induction chemotherapy was associated with lymph node size, tumor grade, invasion region, T stage, and primary tumor. The following issues were significantly associated with an increasing non-response rate to two-cycle induction chemotherapy: increasing lymph node size, moderately differentiated squamous cell carcinoma, invasion of the esophagus along with the thyroid cartilage, and primary tumor in the piriform sinus. Lymph nodes of ≥2.15 cm, moderately differenti- ated tumor grade, or thyroid cartilage invasion were the best cutoff values for patients who did not respond to induction chemotherapy. However, the initial cancer site, cancer stage, and degree of cancer differentiation were not closely related to the efficacy of induction chemotherapy.

Abstract
Dysembryoplastic neuroepithelial tumor (DNT) has traditionally been viewed as rare benign tumors that present with seizure widely considered curable with surgery alone. Most DNTs occur in childhood and young adults. However, rare reported cases occur in infants. This paper reported an infant case of DNT and its diagnosis, differential diagnosis, treatment, molecular features and prognosis based on the review of current literatures. The age onset of this patient was only 11 months old. The clinical manifestations were partial seizures and the imaging data untypical; CT and MRI were all supportive of astrocytoma. Typical glioneuronal element histologic features could be seen, which contained oligodendrocyte-like cells attached to bundles of axons and neurons floating in a myxoid interstitial fluid. Meanwhile, some atypical regions could also be seen. These atypical regions showed a mixture of oligodendrocyte-like cells and neurons without a myxoid interstitial fluid, which were easily misdiagnosed. The BRAFV600E mutation was not detected. This patient had a good response to drug therapy. Totally surgical resection of the tumor was conducted. The patient had been seizures free for 6 months. In conclusion, DNT is a rare and well prognostic tumor (WHO grade I), which most often arise in children in the setting of medically refractory epilepsy. The most common tumor location was temporal. Because clinical symptoms, imaging and histological features of DNT and other low-grade gliomas broadly overlap such as ganglioglioma, pilocytic astrocytomas and oligodendroglioma et al., differential diagnosis should be made carefully. The glioneuronal element was the histopathological hallmark of DNT. In addition, some untypical regions should also be called attention. Although BRAFV600E mutation didn't exist in this case, it played a role in differential diagnosis because it has been previously recorded that BRAFV600E mutation was a common feature of DNT. Infant patients have their own characteristics. For example, drug therapy worked well and the imaging data was untypical. Doctors should improve the understanding of this disease to avoid unnecessary radiotherapy or chemotherapy.

Abstract
Systems that exhibit phase competition, order parameter coexistence, and emergent order parameter topologies constitute a major part of modern condensed-matter physics. Here, by applying a range of characterization techniques, and simulations, we observe that in PbTiO3/SrTiO3 superlattices all of these effects can be found. By exploring superlattice period-, temperature- and field-dependent evolution of these structures, we observe several new features. First, it is possible to engineer phase coexistence mediated by a first-order phase transition between an emergent, low-temperature vortex phase with electric toroidal order and a high-temperature ferroelectric a1/a2 phase. At room temperature, the coexisting vortex and ferroelectric phases form a mesoscale, fibre-textured hierarchical superstructure. The vortex phase possesses an axial polarization, set by the net polarization of the surrounding ferroelectric domains, such that it possesses a multi-order-parameter state and belongs to a class of gyrotropic electrotoroidal compounds. Finally, application of electric fields to this mixed-phase system permits interconversion between the vortex and the ferroelectric phases concomitant with order-of-magnitude changes in piezoelectric and nonlinear optical responses. Our findings suggest new cross-coupled functionalities.

Abstract
Objective: To investigate the association between types of obesity and the 10-year-coronary heart disease risk in Tibet and Xinjiang of China. Methods: Using the multi-stage random sampling method, 7 631 participants aged 35 or older were examined under the International Standardized Examination process but with only 5 802 were eligible for analysis, in the 2015-2016 season. Results: The prevalence rates of general obesity, central obesity, visceral obesity and compound obesity were 0.53%, 12.62%, 10.08% and 42.35%, respectively. Out of all the compound obesity cases, 58.65% (1 441/2 457) of them appeared as having all types of obesity in our study. Risk related to the 10-year-coronary heart disease was higher in men than in women [(3.05±4.14)% vs. (1.42±2.37) %, P<0.000 1. Compound obesity (30.16%) showed the highest proportion on the risk of 10-year-coronary heart disease than central obesity (28.01%), visceral obesity (18.46%) or the general obesity (19.35%). After adjustment for confounding factors, results from the multivariate analysis showed the risk in compound obesity was higher than central obesity, visceral obesity or general obesity and was associated with the highest risk on the 10-year-coronary heart disease (OR=2.889, 95%CI: 2.525-3.305). People with anomalous BMI and WC seemed to have had the higher risk (OR=3.168, 95%CI: 2.730-3.677). Conclusions: Obesity was popular in the residents of Tibet and Xinjiang areas of China. Men and people with compound obesity (especially both BMI and WC were abnormal) seemed to carry greater risk on the 10-year-coronary heart disease.

Abstract
OBJECTIVE Previous research indicated that miR-144-3p was associated with the regulation of the carcinogenic processes, but the role of miR-144-3p in glioblastoma (GBM) remains unclear. In this study, we aimed to analyze the role of miR-144-3p in GBM. PATIENTS AND METHODS The expression of miR-144-3p was measured in GBM tissues and adjacent non-malignant tissues using qRT-PCR. The correlation of miR-144-3p with clinicopathological features and prognosis was also analyzed. Cell proliferation, invasion, and migration assay were applied to assess the function of miR-144-3p in vitro. Bioinformatics prediction and luciferase assays were employed to identify the predicted microRNA (miRNA) which regulates Frizzled-7 (FZD7). The levels of FZD7 and FZD7 mRNA were determined by Western blot and RT-PCR. RESULTS The results showed that the miR-144-3p expression was significantly downregulated in tumor tissues and GBM cell lines compared with that in normal brain tissues and the normal human astrocytes. The levels of miR-144-3p were negatively correlated with the status of WHO grade and recurrence. Furthermore, patients with low serum levels of miR-144-3p had a significantly shorter median overall survival rate. Multivariate Cox regression analysis confirmed that low level of miR-144-3p expression predicted poor prognosis independently. Further function assays showed that miR-144-3p inhibited proliferation invasion and migration of GBM cells. Finally, miR-144-3p was demonstrated to bind to the wild-type 3' untranslated region of FZD7 but not with its mutant. CONCLUSIONS The results of the present study indicate that miR-144-3p suppresses tumor metastasis by targeting FZD7. This work also provides strong evidence that miR-144-3p is an independent prognostic factor for patients with GBM.

Abstract
OBJECTIVE To investigate the liver pathological characteristics and the clearance rate of hepatitis B surface antigen (HBsAg) with antiviral treatment for 1 to 7 years old children with heptitis B e antigen(HBeAg)-negative chronic hepatitis B. METHOD A total of 49 cases with HBeAg-negative chronic hepatitis B were treated with interferon (IFN) or IFN treatment for 6 months added with lamivudine, and were followed up for at least 6 months.Retrospective analysis was performed on the liver pathological characteristics, the efficacy of antivirus treatment and its influencing factors of the HBsAg clearance rate in the cases from June 2006 to December 2013 in the 302 Hospital of People's Liberation Army.The χ(2) test was used to compare the rates. RESULT (1)The median age of cases was 3 years old(1-7 years old), 38 children were male(78%). Cases in the age group 1-2, >2 -3, >3 -4, >4-5, >5-6 and >6-7 were 7, 8, 14, 6, 6 and 8 respectively. HBsAg was 100% positive in mother of the cases. (2)There were 7 children whose pre-treatment alanine aminotransferase (ALT) were ≤80 U/L and pre-treatment ALT>200 U/L in 25 children. There were 24 children whose pre-treatment HBVDNA ≥1×10(7) U/ml. Genetype analysis was detected in 43 children, 3 children were B genotype, 38 were C genotype, 2 were B and C genotype. (3)Liver biopsy was performed in all children. The degree of liver inflammation ≥2 was seen in 48 (98%) children.Severe liver fibrosis and cirrhosis were found in 21(43%) children. (4)In the age group 1-2, >2-3, >3-4, >4-5, >5-6 and >6-7 years old , the clearance of HBsAg was 5, 6, 2, 1, 0 and 0 respectively. The HBsAg clearance rate between 1-3 years old group and 3-7 years old group has significant difference ((73%(11/15) vs. 9%(3/34), χ(2)=18.180, P=0.000). (5)The clearance of HBsAg in male group was 11, but 3 in female group.It showed no significant difference between two groups (χ(2)=0.073, P=0.787). (6) The clearance rate of HBsAg were 0, 24%(4/17) and 40%(10/25) in the groups of pre-treatment ALT ≤80 U/L, 80<ALT≤200 U/L and ALT >200 U/L, respectively. There were no significant difference between the groups of ALT≤200 U/L and ALT > 200 U/L(χ(2)=2.223, P=0.136). In the groups with pre-treatment HBV DNA <1×10(7)U/ml and HBV DNA≥1×10(7)U/ml, the clearance rate of HBsAg was 28%(7/25) and 29%(7/24). There were no significant elifference between two groups(χ(2)=0.008, P=0.928). (7)The clearance rate of HBsAg was 33%(7/21) in children with severe liver fibrosis and cirrhosis, while 25%(7/28) in children who had no severe liver fibrosis and cirrhosis.There were no significant difference between two groups(χ(2)=0.408, P=0.523). CONCLUSION There are obvious liver injuries and severe liver fibrosis in 1-7 years old children with HBeAg-negative chronic hepatitis B. The HBsAg clearance rate in the children with antiviral treatment correlated with age, among those who received antiviral treatment before 3 years old, the HBsAg clearance rate is relatively higher.

Abstract
OBJECTIVE To evaluate the clinical validity of a new ultrahigh-throughput non-invasive prenatal test (NIPT) based on combinatorial probe-anchor ligation (cPAL) sequencing of cell-free fetal DNA (cffDNA) using centralized testing. METHODS Maternal plasma samples were obtained from 10 594 singleton pregnancies in high-risk populations at 20 centers in China, including 8155 that were collected retrospectively and 2439 prospectively. Fetal outcome data and karyotyping results were documented as gold standard and were double blinded during NIPT. The clinical performance of the ultrahigh-throughput sequencing method, cPAL, for NIPT was validated by evaluating its sensitivity, specificity and positive predictive value (PPV) in detecting trisomies 21, 18 and 13 as the centralized testing mode in the reference laboratory. To ensure stable and reproducible performance of centralized cPAL-based NIPT in detecting trisomies, a series of quality-control systems, including sequencing of two sets of artificial samples, were employed and evaluated. RESULTS Ten prospective cases were excluded from the study because of incomplete clinical data. Four prospective samples failed to generate a NIPT result due to assay failure, presenting a failure rate of 0.16% (4/2429). A total of 168 retrospective cases and 47 prospective cases had a positive NIPT result for trisomy, giving respective positive rates of 2.06% and 1.94%. Four false-positive and no false-positive cases were observed in the retrospective and prospective groups, respectively, resulting in PPV of 97.62% (95% CI, 94.02-99.35%) and 100% (95% CI, 92.45-100%), respectively. In the retrospective group, sensitivity and specificity were, respectively, 100% (95% CI, 97.07-100%) and 99.98% (95% CI, 99.94-100%) for trisomy 21, 100% (95% CI, 97.75-100%) and 99.98% (95% CI, 99.94-100%) for trisomy 18, and 100% (95% CI, 15.81-100%) and 100% (95% CI, 99.95-100%) for trisomy 13. In the prospective group, sensitivity and specificity were, respectively, 100% (95% CI, 90.75-100%) and 100% (95% CI, 99.85-100%) for trisomy 21, 100% (95% CI, 63.06-100%) and 100% (95% CI, 99.85-100%) for trisomy 18, and 100% (95% CI, 2.50-100%) and 100% (95% CI, 99.85-100%) for trisomy 13. CONCLUSION In this multicenter study with a full quality-control system, NIPT by centralized cPAL-based testing showed high stability and performance comparable to those of previous validation studies in high-risk populations.

Abstract
Objective: To investigate the association between body fat percentage (BFP), visceral fat index (VFI) and Cardiometabolic Risk Factor Clustering (CRFC), among population aged 35 or older in Tibet and Xinjiang areas. Methods: Using the stratified multi-stage random sampling method, 7 571 residents aged 35 or above were examined with international standardized examination between 2015 and 2016. Of the eligible 5 643 participants, association of BFP and VFI with CRFC was defined as having two or more of the four risk factors: hypertension, diabetes mellitus, high TG and low HDL-C, at the same time. Logistic regression analysis and receiver operating characteristic (ROC) curve analysis were employed to further explore the relationships. Results: The overall prevalence of CRFC among aged 35 and older population in Tibet and Xinjiang areas was 9.78%. BFP and VFI were divided into four groups by quartile. After adjustment for age, gender, race, cigarette smoking, alcohol consumption, education attainments, and altitude of residence, ORs of CRFC seemed to have increased with BFP and VFI. Compared with people having BFP of 5.0%-27.0%, the OR(95% CI) were 1.15(0.86-1.54), 1.48(1.05-2.07) and 1.72(1.10-2.68) for the ones who presented 27.1%-31.7%, 31.8%-36.6% and 36.7%-50.0% of BFP. Compared to people of having 1-6 of VFI, with OR (95%CI) as 1.20(0.81-1.79), 1.91(1.30-2.80) and 3.91(2.64-5.77) for the ones having 7-9, 10-13 and 14-30 of VFI. Areas under the curve (AUC) of CRFC appeared as 0.55 for BFP and 0.70 for VFI, respectively, with statistically significant difference (P<0.01). Conclusion: Both BFP and VFI levels were closely associated with CRFC while VFI seemed to have a better predictive value than the BFP.

Abstract
OBJECTIVE We evaluated the efficacy of surfactant therapy and assisted ventilation on morbidity and mortality of neonates with birth weight (BW) ⩾1500 g and hypoxemic respiratory failure (HRF). STUDY DESIGN We retrospectively analyzed 5650 patients with BW ⩾1500 g for incidence, management and outcome of HRF, defined as acute hypoxemia requiring mechanical ventilation and/or nasal continuous positive airway pressure ⩾24 h. The patients were allocated into groups of moderate preterm (1735, 30.7%), late preterm (1431, 25.4%), early term (ETM, 986, 17.5%), full term (1390, 24.6%) and post term (79, 1.4%), with gestational age ⩽33, 34 to 36, 37 to 38, 39 to 41 and ⩾42 weeks, respectively. RESULTS In the five groups, 66.9, 42, 21.6, 12.8 and 5.1% had respiratory distress syndrome (RDS). For pneumonia/sepsis and meconium aspiration syndrome (MAS), the proportion was 13.8%, 25.4%, 38.0%, 52.5% and 76.0%, respectively. Surfactant was given to 21.9% (n=1238) of HRF and 51.2% (n=1108) of RDS. Survival rates of RDS were 82.2%, 87.8%, 84.5%, 77.1% and 75.0%, respectively (numbers needed to treat was 8 to 11 for surfactant benefit). Overall mortality rate of HRF was 21%, or 17.9%, 14.7%, 25.6%, 28.9% and 39.2%, respectively. Mortalities of MAS and pneumonia/sepsis were 29.4 and 27.6%. Relative risk of death was associated with initial disease severity, female gender, mechanical ventilation and congenital anomalies by multivariate logistic regression analysis. CONCLUSION Surfactant was effective for infants with RDS and BW ⩾1500 g, and different incidences and outcome of HRF among GA groups reflected standard of perinatal and respiratory care in emerging neonatal intensive care unit network.

Abstract
BACKGROUND Androgenetic alopecia (AGA), or male pattern baldness (MPB), is the most common form of hair loss in males. A combination of genetic and androgen causes have been suggested as factors that contribute to the development of AGA. However, the specific molecular mechanisms that underly AGA remain largely unknown. Long non-coding RNAs (lncRNAs), a new class of regulatory non-coding RNAs that are longer than 200 nucleotides, have been shown to play important roles in a number of cellular processes, including transcription, chromosome remodelling and post-transcriptional processing. The dysregulation of lncRNAs is associated with many forms of diseases, but it remains unknown whether lncRNAs are associated with AGA. OBJECTIVE The aim of this study was to identify AGA-associated lncRNAs and predict the potential roles of these lncRNAs in AGA. METHODS A genomewide microarray was used to identify lncRNAs that are differentially expressed between AGA and adjacent normal tissues. Real-time qRT-PCR was used to validate the microarray data. RESULTS A large number of lncRNAs were differentially expressed (fold change >2.4) between AGA and adjacent normal tissues. Of these, 770 were upregulated and 1373 were downregulated. Moreover, pathway analysis revealed that 53 functional pathways were associated with the upregulated transcripts, while 11 pathways were associated with the downregulated transcripts. CONCLUSION To our knowledge, this is the first study to investigate AGA-associated lncRNAs. lncRNA profiles are altered in AGA, and these lncRNAs and their target genes may serve as novel candidates for preventing and treating AGA.

Abstract
AIM To evaluate in vitro the physicochemical properties, cytotoxicity and calcium phosphate nucleation of an experimental light-curable pulp capping material composed of a resin with antibacterial monomer (MAE-DB) and Portland cement (PC). METHODOLOGY The experimental material was prepared by mixing PC with a resin containing MAE-DB at a 2 : 1 ratio. Cured pure resin containing MAE-DB served as control resin. ProRoot MTA and Dycal served as commercial controls. The depth of cure, degree of monomer conversion, water absorption and solubility of dry samples, calcium release, alkalinizing activity, calcium phosphate nucleation and the cytotoxicity of materials were evaluated. Statistical analysis was carried out using anova followed by Tukey's HSD test (equal variance assumed) or Tamhane test (equal variance not assumed) and independent-samples t-tests. RESULTS The experimental material had a cure depth of 1.19 mm, and the mean degree of monomer conversion was 70.93% immediately post-cure and 88.75% at 24 h post-cure. The water absorption of the experimental material was between those of MTA and Dycal, and its solubility was significantly less (P < 0.05) than that of Dycal and higher than that of MTA. The experimental material exhibited continuous calcium release and an alkalinizing power between those of MTA and Dycal throughout the test period. Freshly set experimental material, control resin and all 24-h set materials had acceptable cytotoxicity. The experimental material, MTA and Dycal all exhibited the formation of apatite precipitates after immersion in phosphate-buffered saline. CONCLUSIONS The experimental material possessed adequate physicochemical properties, low cytotoxicity and good calcium phosphate nucleation.

Abstract
To study the mechanism by which monochromatic light affects gonadotrophin-releasing hormone (GnRH) expression in chicken hypothalamus, a total of 192 newly-hatched chicks were divided into intact, sham-operated and pinealectomy groups and exposed to white (WL), red (RL), green (GL) and blue (BL) lights using a light-emitting diode system for 2 weeks. In the GL intact group, the mRNA and protein levels of GnRH-I in the hypothalamus, the mean cell area and mean cell optical density (OD) of GnRH-I-immunoreactive (-ir) cells of the nucleus commissurae pallii were decreased by 13.2%-34.5%, 5.7%-39.1% and 9.9%-17.3% compared to those in the chicks exposed to the WL, RL and BL, respectively. GL decreased these factors related to GnRH-I expression and the effect of GL was not observed in pinealectomised birds. However, the mRNA and protein levels of hypothalamic gonadotrophin-inhibitory hormone (GnIH) and GnIH receptor (GnIHR), the mean cell area and mean cell OD of the GnIH-ir cells of the paraventricularis magnocellularis, and the plasma melatonin concentration in the chicks exposed to GL were increased by 18.6%-49.2%, 21.1%-60.0% and 8.6%-30.6% compared to the WL, RL and BL intact groups, respectively. The plasma melatonin concentration showed a negative correlation with GnRH-I protein and a positive correlation with GnIH and GnIHR proteins. Protein expression of both GnRH-I and GnIHR showed a negative correlation in the hypothalamus. After pinealectomy, GnRH-I expression increased, whereas plasma melatonin concentration, GnIH and GnIHR expression decreased, and there were no significant differences among the WL, RL, GL and BL groups. Double-labelled immunofluorescence showed that GnIH axon terminals were near GnRH-I neurones, some GnRH-I neurones coexpressed with GnIHR and GnIH neurones coexpressed with melatonin receptor subtype quinone reductase 2. These results demonstrate that green light inhibits GnRH-I expression by increasing melatonin secretion and stimulating melatonin receptor-GnIH-GnIH receptor pathway in the chick brain.

Abstract
Many studies have been carried out to examine whether there is an association between CDKN2A polymorphisms and cancer risk, but the results from these studies were controversial. In the present study, we performed a meta-analysis to clarify whether there is an association of CDKN2A polymorphisms and cancer risk. Published reports were searched in PubMed and Google Scholar. ORs with 95% CIs were calculated in the dominant models. Twenty six case-control studies that met the inclusion criteria were included in the final meta-analysis. Overall, we found that rs3731249, rs11515, and rs3088440 polymorphisms were not associated with cancer risk (OR=1.27, 95%CI: 0.79-2.03; OR=0.91, 95%CI: 0.79-1.03; OR=1.02, 95%CI: 0.95-1.09). However, CDKN2A rs3731249 polymorphism was significantly associated with ovarian cancer risk (OR=0.78, 95%CI: 0.65-0.95). A significant association was observed in Asian with rs11515 polymorphism (OR=0.48, 95%CI: 0.28-0.83). This meta-analysis shows that CDKN2A rs3731249 polymorphism was significantly associated with ovarian cancer risk. In addition, CDKN2A rs11515 polymorphism might associate with cancer risk in Asians.

Abstract
Salinity, which is one of the most common abiotic stresses, may severely affect plant productivity and quality. Although plant lectins are thought to play important roles in plant defense signaling during pathogen attack, little is known about the contribution of plant lectins to stress resistance. We cloned and functionally characterized a rice jacalin-related mannose-binding lectin gene, OsJRL, from rice 'Nipponbare'. We analyzed the expression patterns of OsJRL under various stress conditions in rice. Furthermore, we overexpressed OsJRL in Escherichia coli and rice. The cDNA of OsJRL contained a 438 bp open reading frame, which encodes a polypeptide of 145 amino acids. OsJRL was localized in the nucleus and cytoplasm. Real time PCR analyses revealed that OsJRL expression showed tissue specificity in rice and was upregulated under diverse stresses, namely salt, drought, cold, heat and abscisic acid treatments. Overexpression of OsJRL in E. coli enhanced cell viability and dramatically improved tolerance of high salinity. Overexpression of OsJRL in rice also enhanced salinity tolerance and increased the expression levels of a number of stress-related genes, including three LEA (late embryogenesis abundant proteins) genes (OsLEA19a, OsLEA23 and OsLEA24), three Na+ transporter genes (OsHKT1;3, OsHKT1;4 and OsHKT1;5) and two DREB genes (OsDREB1A and OsDREB2B). Based on these results, we suggest that OsJRL plays an important role in cell protection and stress signal transduction.

Abstract
OBJECTIVE The present study introduces the application of percutaneous epididymal sperm aspiration (PESA) for diagnosis of obstructive azoospermia and non-obstructive azoospermia. PATIENTS AND METHODS 96 cases diagnosed with azoospermia were selected, standard methods were used to measure testicular volume, chemiluminescence was used to test serum sexual hormone levels, and No. 7 butterfly needles were applied to puncture the head of the epididymis and aspirate epididymal luminal fluid. RESULTS Among 96 cases of azoospermia, sperm was found in the epididymal luminal fluid of 49 cases, among which there were 41 cases with normal testicular volume and 8 cases with low volume. 39 cases had normal serum FSH levels, and 10 cases had increased serum FSH levels. There were 47 cases with no sperm, among which there were 26 cases with normal testicular volume and 21 cases with low volume. 29 cases had normal serum FSH levels, and 18 cases had increased levels. The success rate of puncture for patients with normal testicular volume was higher than that of patients with low volume, and the difference was statistically significant (p < 0.05). The success rate of puncture for patients with normal serum FSH levels was higher than that of patients with increased levels, and the difference was statistically significant (p < 0.05). CONCLUSIONS PESA is simple and efficient, and is a feasible method for diagnosis of azoospermia.

Abstract
Abstract
Background: Although taxanes are a mainstay of breast cancer treatment, some cases are resistant to these drugs. This is a crucial issue in breast cancer therapy. In the emerging era of next-generation sequencing, it is possible to obtain extensive genomic information on individual tumors in a very short time. Using this technology, it was reported that specific mutations might affect therapeutic efficacy and induce resistance to specific treatment.
Objective: The aim of this study was to investigate the mechanisms of taxane resistance using whole exon sequencing and expression analyses in human breast cancer tissues.
Materials and Methods: We selected six breast cancer patients whose tumors responded well to anthracycline treatment but suffered disease progression on taxane treatment. We then performed whole exon sequencing on these samples using HiSeq (Illumia). In this way, we identified somatic mutations of candidate genes considered to be instrumental for mediating resistance to taxanes. Next, we performed mRNA expression analyses of these candidate genes in a further 122 breast cancers treated with taxanes at our institute. Finally, we correlated mRNA expression levels of these genes with clinicopathological factors and prognosis.
Results: We identified 9 mutations common to all 6 patients analyzed in this study, and a further 16 mutations shared by 5 of them. Kaplan-Meier analyses showed that high level mRNA expression of 3 of these 25 genes was significantly associated with poorer disease-free survival. Moreover, high level mRNA expression of one of these three genes was significantly associated with worse overall survival. However, there were no significant correlations between expression levels of these three genes and any clinicopathologeical features.
Conclusion: Using next-generation sequencing, we have identified three candidate genes involved in resistance to taxane treatment in breast cancer. We are now analyzing the functional attributes of these three genes.

Abstract
Hymenocallis littoralis growing in southern China has been recently extensively damaged by virus-like symptoms of necrosis, chlorosis, and ringspot. Of 44 plant samples collected from Yunnan, Guangxi, Guangdong, and Fujian provinces in southern China, 32 were infected with hippeastrum chlorotic ringspot virus (HCRV). Phylogenetic analysis based on the N gene divided the virus samples into two branches suggesting a geographic distribution attributed to the initial stage of a founder effect. The N gene was under purifying selection pressure and most of the deleterious mutants had been removed. Both the population dynamics and genetic analyses suggested that populations of HCRV in southern China are spreading.

Abstract
Multi-functional nanomaterials possess unique properties, facilitating both therapeutic and diagnostic applications among others. Herein, we developed dual-functional lipid-like nanoparticles for simultaneous delivery of mRNA and magnetic resonance imaging (MRI) contrast agents in order to express functional proteins and provide real-time visualization. TT3-Gd18 LLNs were identified as a lead formulation, which was able to encapsulate 91% of mRNA and 74% of Gd. This formulation showed a comparable or a slightly higher delivery efficiency of mRNA compared to the initial TT3 LLNs. Moreover, a strong MRI signal was observed in the cell pellets treated with TT3-Gd18 LLNs. More importantly, TT3-Gd18 LLNs demonstrated an efficient delivery of mRNA and Gd contrast agents in vivo.

Abstract
OBJECTIVES Aging is associated with glucose and lipid metabolism disorder. We aimed to examine the effects of mussel peptides on protecting against aging by regulating glucose and lipid metabolism. METHODS For the aging model, d-galactose (200 mg/kg) was administered subcutaneously to 8-month-old mice for 8 weeks. Mussel peptides (1,000 mg/kg) were simultaneously administered by intragastric gavage. The glucose and lipid metabolism profiles, aging phenotype and peroxisome proliferator-activated receptors (PPARs) expression in the liver and adipose tissue of ICR mice were measured. RESULTS D-galactose-treated mice showed pronounced fat deposition and impaired glucose and lipid homeostasis, along with increased oxidative damage and aging. Mussel peptides improved metabolic status by reducing serum glucose and triglyceride levels, insulin resistance and hepatic free fatty acid, as well as enhancing serum high-density lipoprotein (HDL) level and hepatic glycogen content, accompanied with amelioration of aging phenotype and fat deposition. Moreover, mussel peptides ameliorated oxidative stress in aged liver tissues and promoted expression of peroxisome proliferator activated receptors alpha (PPARα) and gamma (PPARγ) in liver and adipose tissues. CONCLUSIONS These results indicate that mussel peptides protect against lipid metabolic disorders associated with aging via maintaining oxidative stress homeostasis and elevated expression levels of PPARs.

Abstract
Diabetic retinopathy is one of most common diabetic microvascular complications. In recent years the incidence of the disease has increased, hence early diagnosis and treatment are of great importance. In order to find reliable biological indexes to diagnose and treat type-two diabetes mellitus promptly, this study focused on the correlation between Cystatin C (Cys C) and retinopathy of type-two diabetes mellitus patients. One hundred and eighty type-two diabetes mellitus patients and one hundred healthy controls (the control group) were chosen in this study. Of the patients ninety-eight patients had typetwo diabetes mellitus without retinopathy (non-diabetic retinopathy group) and eighty-two had typetwo diabetes mellitus with retinopathy (diabetic retinopathy group). Correlation of Cys C and typetwo diabetic retinopathy was analyzed by examining the waist-hip ratio, fasting blood glucose (FBG), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), glycosylated hemoglobin (HbA1c), and Cys C of both groups. The results showed that FBG, TC, TG, LDL-C, HbA1c, Cys C in the type-two diabetes mellitus patients group were higher than those of the control group (P less than 0.05). Age, course of diabetes, FBG, HbA1c, and Cys C levels were statistically significant in both the DR group and NDR group (P less than 0.05). The result of logistic regression analysis indicates that there was a positive correlation between type-two diabetic retinopathy development and age, course of diabetes, and Cys C level (P less than 0.05). Thus, it can be seen that changes of Cys C levels can assist early diagnosis and treatment of diabetic retinopathy to some extent. The patients with high Cys C level, long course of diabetes, and old age are more likely to have diabetic retinopathy.

Abstract
UNLABELLED This study aims to determine what factors are associated with increased risk of fracture among patients with HIV, in particular whether an important medication used to treat HIV, tenofovir, is associated with fracture. Our study found that while co-infection with hepatitis C and markers of HIV severity were associated with fracture, tenofovir was not. INTRODUCTION Growing evidence suggests that tenofovir disoproxil fumarate decreases bone density among patients with HIV, but there are conflicting reports as to whether this decrease in bone density translates to higher fracture risk. We aimed to determine what factors were associated with an increased risk of fracture for patients with HIV, in particular whether tenofovir is associated with elevated fracture risk. METHODS We conducted a retrospective cohort study at two tertiary care hospitals in Boston, MA, between 2001 and 2012 to determine whether tenofovir use is associated with elevated all-site fracture risk, as compared to other antiretroviral medications. We also examined other potential factors associated with fracture among patients with HIV. RESULTS We identified 1981 HIV-infected patients who had at some point used tenofovir and 682 patients who had not. The mean age was 43 years, and 72 % were male. The hepatitis C co-infection rate was 28 %, about 40 % had nadir CD4 count <200, and about 40 % had a history of an AIDS-defining illness. We did not find an association between risk of fracture and tenofovir disoproxil fumarate (TDF) (adjusted RR (aRR) 0.8, 95 % CI 0.6-1.1). However, co-infection with hepatitis C did increase risk of fracture (aRR 1.6, 95 % CI 1.1-2.3), as did nadir CD4 count <200 (aRR 3.1, 95 % CI 1.9-5.0) and history of AIDS-defining illness (aRR 1.6, 95 % CI 1.1-2.2). CONCLUSION There was no association found between fracture and tenofovir use, but there were associations between co-infection with hepatitis C and markers of advanced HIV disease and fracture.

Abstract
Diarrhoea is a common cause of death in children and weaned animals. Recent research has found that serotonin (5-HT) in the gastrointestinal tract plays an important role in regulating growth and the maintenance of mucosa, which protect against diarrhoea. To determine the influence of 5-HT on intestinal epithelium cell renewal under weaned stress diarrhoea, a weaned-stress diarrhoea mouse model was established with senna infusion (15 mL/Kg) via intragastric administration and stress restraint (SR). Mice with an increase in 5-HT were induced by intraperitoneal injection with citalopram hydrobromide (CH, 10 mg/Kg). The results demonstrated that compared with the control animals, diarrhoea appeared in weaned stress mice and the 5-HT content in the small intestine was significantly increased (P<0.05). Further, the caspase-3 cells and cells undergoing apoptosis in the small intestine were significantly increased, but the VH (villus height), V/C (villus height /crypt depth), and PCNA-positive rate significantly decreased. Compared with the control animals, CH increased the intestinal 5-HT content, caspase-3 cells and cells undergoing apoptosis but decreased the VH and V/C. Compared with both control and weaned stress animals, weaned stress animals that were pre-treated with CH showed higher 5-HT concentrations, positive caspase-3 cells and cells undergoing apoptosis but lower VH, V/C and PCNA-positive rate. In vitro, a low concentration of 5-HT inhibit, IEC-6 cell line apoptosis but a higher concentration of 5-HT promoted it. Therefore, weaned stress diarrhoea mice were accompanied by a 5-HT increase in the small intestine and vice versa, and the increase in 5-HT induced by CH caused diarrhoea. In brief, 5-HT and diarrhoea slowed the intestinal epithelium cell renewal and injured the abortion function and mucosal barrier by decreasing VH, V/C and proliferation and increasing epithelium cell apoptosis.

Abstract
Objective: To investigate the relationship of single nucleotide polymorphisms of Multi-drug resistance (ABCB1/MDR1) gene with Aspirin resistance (AR) in patients with ischemic stroke. Methods: Three hundred ischemic stroke patients from Department of Neurology, Affiliated Hospital of Qingdao University were collected from September 2014 to May 2016. According to the results of Thromboelastogram (TEG), the patients were divided into aspirin resistance (AR) group and aspirin sensitive (AS) group. The genotypes of ABCB1 gene (C1236T, G2677T/A, C3435T) were detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and direct sequencing. Result: Linkage disequilibrium was found among the three loci (D'=0.8; r2=0.9). The T allele frequency of C3435T in AR group and AS group was 57.3% and 43.1% respectively, and the difference was statistically significant (χ2=9.143, P=0.002). The frequency of genotypes CT+ TT in AR group was higher than AS group, and the difference was also significant (χ2=4.369, P=0.037). But there was no difference in allele frequency and genotype distribution of C1236T and G2677T/A between the two groups.Haplotypes constituted by the three loci were analyzed, and the OR value of haplotype (C-T-T) was 1.602 (χ2=5.374, P=0.02), the OR value of haplotype (C-G-C) was 0.495 (χ2=8.775, P=0.003), the OR value of haplotype (T-G-C) was 3.010 (χ2=5.846, P=0.015), while the OR value of haplotype (T-T-T) was 3.308 (χ2=4.650, P=0.031). Conclusions: The polymorphisms of C3435T in the ABCB1 gene have a relationship with AR in the patients with ischemic stroke. The haplotypes (C-T-T, T-G-C, T-T-T) are also related to the AR in the patients with ischemic stroke.

Abstract
OBJECTIVE To determine the clinicopathological significance of the DNA methyltransferase 3B (DNMT3B) overexpression in endometrial carcinomas and to evaluate its correlation with hormone receptor status. METHODS Immunohistochemistry was performed to assess the expression of DNMT3B and hormone receptors in 104 endometrial carcinomas. RESULTS DNMT3B overexpression occurred frequently in endometrioid carcinoma (EC, 54.8%) more than in nonendometrioid carcinoma (NEC, 30.0%) with statistical significance (P=0.028). Furthermore, there was a trend that EC with worse clinico-pathological variables and shorter survival had a higher DNMT3B expression, and the correlation between DNMT3B and tumor grade reached statistical significance (P=0.019).A negative correlation between DNMT3B and estrogen receptor (ER) or progesterone receptor (PR) expression was found in EC. NMT3B overexpression occurred frequently in the ER or PR negative subgroups (78.9%, 86.7%) more than in the positive subgroups (47.7%, 47.8%) with statistical significance (P=0.016, P=0.006). In addition, the DNMT3B overexpression increased in tumors with both ER and PR negative expression (92.9%, P=0.002). However, no such correlation was found in NEC (P>0.05). Sequence analyses demonstrated multiple ER and PR binding sites in the promoter regions of DNMT3B gene. CONCLUSION This study showed that the expression of DNMT3B in EC and NEC was different. DNMT3B overexpression in EC was associated with the worse clinicopathological variables and might have predictive value. The methylation status of EC and NEC maybe different. In addition, in EC, DNMT3B overexpression negatively correlated with ER or PR expression. In NEC, the correlation between DNMT3B and ER or PR status was not present.
