Abstract
Objective: To analyze the clinical features of postpartum hepatitis flares in pregnant women with hepatitis B virus (HBV) infection. Methods: A retrospective study was conducted. Patients who met the enrollment criteria were included. Liver function and HBV virology tests were collected from pregnant women with chronic HBV infection at delivery, 6, 24, 36, and 48 weeks after delivery through the hospital information and test system. Additionally, antiviral therapy types and drug withdrawal times were collected. Statistical analysis was performed on all the resulting data. Results: A total of 533 pregnant women who met the inclusion criteria were included, with all patients aged (29.5±3.7) years old. A total of 408 cases received antiviral drugs during pregnancy to interrupt mother-to-child transmission. There was no significant difference in the levels of alanine aminotransferase (ALT, z = -1.981, P = 0.048), aspartate aminotransferase (AST, z = -3.956, P < 0.001), HBV load (z = -15.292, P < 0.001), and HBeAg (z = -4.77, P < 0.001) at delivery in patients who received medication and those who did not. All patients ALT, AST, total bilirubin, direct bilirubin, and albumin showed an upward trend within six weeks after delivery. A total of 231 cases developed hepatitis within 48 weeks after delivery. Among them, 173 cases first showed ALT abnormalities within six weeks postpartum. Conclusion: Hepatitis flare incidence peaked six weeks after delivery or six weeks after drug withdrawal in pregnant women with chronic HBV infection.

Abstract
This study aimed to compare the pharmacokinetics and bioavailability of 2 formulations: a fixed-dose combination tablet containing allisartan isoproxil (AI) and indapamide sustained-release (SR), and a monotherapy combination of AI and indapamide SR, in healthy Chinese subjects. A monocentric, open-label, single-dose, randomized, 2-way crossover study design was implemented. A total of 38 healthy male and female volunteers were equally divided into 2 treatment sequences. The analysis of plasma concentrations was conducted using a nonstereospecific liquid chromatography/tandem mass spectrometric method. The primary pharmacokinetic parameters were calculated using a noncompartmental model. Safety assessments were performed throughout the study. For the fixed-dose combination and monotherapy combination, the mean values of EXP3174 (metabolite of AI) Cmax , AUC0-t , and AUC0-∞ were 987 and 999 ng/mL, 8059 and 7749 ng/mL h, and 8332 and 8007 ng/mL h, respectively. The corresponding values for indapamide were 27 and 32 ng/mL, 1002 and 1105 ng/mL h, and 1080 and 1172 ng/mL h. No serious adverse events were reported during the study. The combination tablet containing 240 mg of AI and 1.5 mg of indapamide SR met the bioequivalence standards. Additionally, both formulations were tolerated and had good safety profiles in the research.

Abstract
Allisartan isoproxil (AI) is an angiotensin II type 1 receptor blocker and be converted into the active substance EXP3174 in vivo. We evaluated the drug-drug interactions of AI and an indapamide sustained-release (Ind SR) preparation, as well as the pharmacokinetic characteristics and safety of AI and Ind SR in healthy subjects. The trial was set up in 6 sequences and 3 cycles, and each cycle contained a 7-day washout period. Subjects received 3 different trial drugs (A, AI; B, Ind SR; C, AI + Ind SR) during 3 different cycles. Twenty-four subjects were enrolled in the clinical trial. Of these, 22 completed the study, 2 subjects dropped out due to adverse events (AEs). For subjects given AI alone or combined with Ind SR, the pharmacogenetic parameters Cmax and the geometric mean ratio of steady state (combined/single) of EXP3174 was 130%. The geometric mean ratio of area under the concentration-time curve over the dosing interval at steady state (combined/single use) was 144.5%. Therefore, the combination of Ind SR had an impact on the pharmacokinetics of AI. Then, the results indicated that the AI combination had no effect on the pharmacokinetics of Ind SR. Serious AEs did not occur. The AEs in this clinical trial were the same as those for AI and Ind SR. Combined administration resulted in 2 cases (2 subjects) of Grade 3 hypotension and 1 case of Grade 3 hypotension with AI alone. Considering that this trial included healthy volunteers, the risk of hypotension was expected to be manageable.

Abstract
BACKGROUND Ventricular septal defect (VSD) is the most common subtype of congenital heart disease. In the present study, we aimed to determine whether chromosome aberration was associated with the occurrence of VSD and evaluate the association of VSD size, location and chromosome aberration with adverse outcomes in the Chinese fetuses. METHODS Fetuses with VSD and comprehensive follow-up data were included and evaluated retrospectively. Medical records were used to collect epidemiological data and foetal outcomes. For VSD fetuses, conventional karyotype and microarray analysis were conducted. After adjusting confounding factors by using multivariable logistic regression analyses, the association between chromosome variations and VSD occurrence was explored. The association between defect size, location and chromosome aberrations and adverse foetal outcomes was also investigated. RESULTS Chromosome aberration was the risk factor for VSD occurrence, raising 6.5-fold chance of developing VSD. Chromosome aberration, peri-membranous site and large defect size of VSD were significant risk factors of adverse fetal outcome. Chromosome aberrations, including pathogenic copy number variations (CNVs) and variations of uncertain significance (VUS), were both risk factors, increasing the risk of the adverse fetal outcome by 55.9 times and 6.7 times, respectively. The peri-membranous site would increase 5.3-fold risk and defects larger than 5 mm would increase the 7.1-fold risk for poor fetal outcome. CONCLUSIONS The current investigation revealed that chromosomal abnormalities, large defects, and the peri-membranous site were all risk factors for poor fetal outcomes. Our study also indicated that chromosome aberration was one of risk factors for the VSD occurrence.

Abstract
Aim To study platelet adhesion mediated by von Willebrand factor (VWF) in patients with premature ischemic heart disease (IHD).Material and methods This study enrolled 58 patients with stable IHD, including 45 men younger than 55 years with the first manifestation of IHD at the age of <50 years and 13 women younger than 65 years with the first manifestation of IHD at the age of <60 years. The control group consisted of 33 patients, 13 men younger than 55 years and 20 women younger than 65 years without IHD. Platelet adhesion to the collagen surface at the shear rate of 1300 s-1 was studied by evaluating the intensity of scattered laser light from the collagen-coated optical substrate in a flow chamber of a microfluidic device after 15-min circulation of whole blood in the chamber. Decreases in platelet adhesion after addition to the blood of monoclonal antibodies (mAb) to platelet receptors glycoproteins Ib (GPIb) to inhibit the receptor interaction with VWF were compared for patients of both groups. Results In patients with premature IHD, the decrease in platelet adhesion following the platelet GPIb receptor inhibition was significantly less than in patients of the control group (74.8 % (55.6; 82.7) vs. 28.9 % (-9.8; 50,5), p <0.001). For the entire sample, the median decrease in platelet adhesion following the GPIb receptor inhibition was 62.8 % (52.2; 71.2). With an adjustment for traditional risk factors of IHD, a decrease in platelet adhesion of >62.8% after blocking GPIb receptors increased the likelihood of premature IHD (OR=9.84, 95 % CI: 2.80-34.59; p <0.001).Conclusion Blocking the interaction of GPIb receptors with VWF in patients with premature IHD and increased shear rate induced a greater decrease in platelet adhesion than in patients without this disease. This suggested that an excessive interaction of VWF with platelets might contribute to the pathogenesis of premature IHD.

Abstract
A single performance evaluation does not cover all the situations encountered in cement-based plastering mortar applications in walls. This paper proposes a comprehensive performance evaluation method for assessing the cement-based plastering mortar by comprehensively considering the physical characteristics, microstructures, thermal performances, mechanical properties and adsorbability of materials. The relative performances of each test item were compared with standards and previous studies, and the calculation equation of the comprehensive performance value was obtained. In this study, the common cement plastering mortar (CM) and lightweight mortar were mixed with expanded and vitrified beads as aggregates mortar (EVBM), wood fibres, sepiolite and expanded perlite-based plastering mortar (WM) and three types of homemade optimized mortars were moulded as testing specimens. The reference material was marked as CM, and the weights of each parameter in the equation were artificially set according to the applied conditions of the building and restricted by the comprehensive performance value of the ideal plastering mortar at the same time. Through the evaluation of the comprehensive performance and the calculation of these mortars from a case setting of weights, the combined mixing of diatomite, sepiolite with fly ash is better than each single material mixed in mortars, and the comprehensive performance value of mortars with a single function is functional, such as thermal insulation mortar. This paper provides an evaluation method for the comprehensive application of cement-based plastering mortar on the wall.

Abstract
Ectrodactyly-ectodermal dysplasia-cleft (EEC) syndrome is an autosomal dominant disorder characterized by ectrodactyly, ectodermal dysplasia, and orofacial clefting. Reduced penetrance is manifested in these core features and additional under-recognized features, especially in prenatal cases. Here, we present a fetus with EEC syndrome at 22 weeks gestation, in which the cleft lip and palate and the right polycystic kidney are shown by prenatal ultrasound. A de novo missense mutation of R304W in the TP63 gene is confirmed by whole-exome sequencing associated with EEC syndrome. We further investigate the reported TP63-related prenatal cases and provide a more complete picture of the prenatal phenotypic spectrum about EEC. It illustrates the potential severity of genitourinary anomalies in TP63-related disorders and highlights the need to counsel for the possibility of EEC syndrome, given the occurrence of genitourinary anomalies with orofacial cleft or limb deformities.

Abstract
BackgroundTo compare the application of the emerging 3D printing technology and 3D-CT in segmentectomy. And to explore the advantages of 3D printing technology in thoracoscopic segmentectomy.MethodsWe collected the clinical data of 118 patients undergoing thoracoscopic segmentectomy from January 2019 to April 2021 at the Thoracic Surgery Department, the Dianjiang People's Hospital of Chongqing and Southwest Hospital. Among them, 61 patients were in the 3D printing group and 57 patients were in the 3D-CT group respectively. The perioperative data of these two groups of patients were analyzed respectively.ResultsThere were no significant differences between the two groups in age, gender, tumor diameter, pathology, the preoperative complications of diabetes and heart disease. However, the patients with the complications of hypertension in the 3D printing group are significantly more than the 3D-CT group (P = 0.003). Compared with the 3D-CT group, patients in the 3D printing group had significantly shorter operation time (162.7 ± 47.0 vs. 190.3 ± 56.9 min, P = 0.006), less intraoperative fluid input (1,158.5 ± 290.2 vs. 1,433.2 ± 653.3, P = 0.013), and less total intraoperative fluid output, including intraoperative blood loss, urine excretion, and other fluid loss. In addition, there were no statistically significant differences in intraoperative blood loss, 24 h pleural fluid volume, 48 h pleural fluid volume, postoperative chest tube duration, postoperative hospital stay and complications between the two groups of patients (P > 0.05).ConclusionsIn thoracoscopic segmentectomy, the application of 3D printing technology shortens the operation time, reduces intraoperative fluid input and output, guides the operation more safely and effectively, and has better clinical application value.

Abstract
Extranodal NK/T cell lymphoma (ENKL) is a rare subtype of lymphoma that shows a poor clinical outcome. The most common sites are the nasal cavity, nasopharynx, paranasal sinuses, tonsils and larynx. Because of P-glycoprotein expression on ENKL cells, ENKL is resistant to anthracycline-based chemotherapy. L-asparaginase-based chemotherapy with or without radiotherapy shows promising outcomes for advanced ENKL, but has limited efficacy in relapsed/refractory ENKL. immune-checkpoint inhibitors, histone deacetylase inhibitors, and monoclonal antibodies are being investigated. In this review, we summarize the new treatments for ENKL.

Abstract
Allisartan isoproxil (AI) is a blocker of the angiotensin II type 1 receptor. We evaluated the safety and pharmacokinetics of single- and multiple-dose AI in healthy Chinese individuals. Participants were assigned to receive AI or placebo. Plasma concentration of EXP3174 (carboxylic acid derivative) was measured using liquid chromatography-tandem mass spectrometry. Pharmacokinetic parameters were determined by noncompartmental methods. Twelve subjects were enrolled, and the ratio of men to women was 5:1. Main pharmacokinetic parameters of EXP3174 after single and multiple doses of AI were a mean maximum concentration in plasma (Cmax ) of 2242 ± 1037 ng/mL and median time to reach Cmax (Tmax ) of 3.5 hours (2.5-8 hours). The median Tmax, at steady state was 4.0 hours (1.5-8 hours). The mean Cmax at steady state (Cmax, SS ) was 2047 ± 1050 ng/mL. In terms of EXP3174, there was no significant difference in the Cmax, SS , area under the curve from time zero to 24 hours of quantifiable concentration at steady state (AUC0-24 SS ), and AUC0-72 after multiple doses of AI. Serious adverse events did not occur. These data suggest that AI is safe and well tolerated in healthy Chinese individuals at a single dose of 480 or 480 mg once daily for 7 days.

Abstract
OBJECTIVES Diurnal temperature range (DTR) is an important indicator of global climate change. Many epidemiological studies have reported the associations between high DTR and human health. This study investigated the association between DTR and hospitalisations for ischaemic stroke in Hefei, China. STUDY DESIGN This is an ecological study. METHODS Data of daily hospital admissions for ischaemic stroke and meteorological variables from 1 January 2009 to 31 December 2017 were collected in Hefei, China. A generalised additive model combined with distributed lag non-linear model was used to quantify the effects of DTR on ischaemic stroke. The interactive effect between DTR and temperature was explored with a non-parametric bivariate response surface model. RESULTS High DTR was associated with hospitalisations for ischaemic stroke. The adverse effect of extremely high DTR (99th percentile [17.1 °C]) occurred after 8 days (relative risk [RR] = 1.021, 95% confidence interval [CI] = 1.002, 1.041) and the maximum effect appeared after 12 days (RR = 1.029, 95% CI = 1.011, 1.046). The overall trend of the effect of DTR on ischaemic stroke was decreasing. In addition, there was a significant interactive effect of high DTR and low temperature on ischaemic stroke. CONCLUSIONS This study suggests that the impact of high DTR should be considered when formulating targeted measures to prevent ischaemic stroke, especially for those days with high DTR and low mean temperature.

Abstract
Objective: To investigate the therapeutic effect of Jin Long Capsule (JLC) combined with neoadjuvant chemotherapy on the invasive breast cancer, and to explore the mechanism of JLC in inhibiting multidrug resistance of breast cancer. Methods: 200 patients were divided into experimental group and control group (100 cases per group). The control group used TEC regimen for neoadjuvant chemotherapy. And the experimental group was treated with TEC regimen combined with oral JLC. According to the Miller & Payne grading system (MP), the efficacy of neoadjuvant chemotherapy was evaluated based on histopathological changes of breast cancer after neoadjuvant chemotherapy. Adverse effect was evaluated according to the classification criteria of the National Cancer Institute of the United States-The Common Terminology Criteria for Adverse Events (CTCAE) version 3.0. The expression of P-glycoprotein (P-gp), glutathione thiol transferase (GST)-π and topoisomerase Ⅱα (TopoⅡα) in breast cancer tissues before and after neoadjuvant chemotherapy were detected by immunohistochemical staining. Results: There were 83 effective cases (83%) in the experimental group, which was higher than that in the control group (65.0%, P<0.05). The incidence of leukopenia, gastrointestinal reactions and alopecia in grade 3 to 4 of the experimental group were lower than those of the control group (all P<0.05). The positive rates of P-gp, GST-π and TopoⅡα expression in the control group were 65.0% (65/100), 61.0% (61/100) and 69.0% (69/100), respectively, and they were 80.6% (75/93), 78.5% (73/93) and 37.6% (35/93) after chemotherapy. The positive rates of P-gp and GST-π expression were significantly higher than those before chemotherapy (both P<0.05), whereas the positive rate of TopoⅡα expression was significantly lower than that before chemotherapy (P<0.05). In the experimental group, the positive rates of P-gp, GST-π and TopoⅡα expression before chemotherapy were 62.0% (62/100), 63.0% (63/100) and 69.0% (69/100), respectively, while after chemotherapy, they were 68.2% (60/88), 67.0% (59/88) and 63.6% (56/88). There was no significant difference in the positive rates and expression intensity of P-gp, GST-π and TopoⅡα before and after the chemotherapy (P>0.05). Conclusion: Jin Long Capsule (JLC) can inhibit multidrug resistance, improve the efficacy of neoadjuvant chemotherapy, and reduce adverse reactions of breast cancer.

Abstract
RATIONALE Langerhans cell sarcoma (LCS) is a rare, high-grade neoplasm characterized by overtly malignant cytologic features and a poor prognosis. Herein, we present a rare case of langerhans cell histiocytosis (LCH) that later transformed into langerhans cell sarcoma 11 months after the benign mass was excised from soft tissue in the right groin. PATIENT CONCERNS A 41-year-old patient who presented with a mass in the right groin for 3 years earlier after being bitten by ants. DIAGNOSES The patient was diagnosed with langerhans cell sarcoma arising from antecedent langerhans cell histiocytosis. INTERVENTIONS The patient underwent with 6 cycles of a modified etoposide, cyclophosphamide, vindesine, dexamethasone (E-CHOP) regimen. OUTCOMES The patient is currently receiving follow-up care. LESSONS LCH transformed into LCS is a rare case. E-CHOP as an effective first-line therapy to treat LCS cases, but, the mechanism is unclear. Due to their rarity, further data on clinical outcomes are necessary to establish the optimal treatment strategy for LCS.

Abstract
Both vitamin K antagonists (VKAs) and novel oral anticoagulants (NOACs) are effective for stroke prevention in nonvalvular atrial fibrillation (NVAF) patients. This study evaluated the utilization of VKA and NOACs in NVAF patients before and after catheter ablation in China. Prescription data were retrospectively collected between January 1, 2016, and December 31, 2016, including indication of use, dose, renal function, and risk assessment (CHA2DS2-VASc score and HAS-BLED score) in Zhongshan Hospital of Fudan University. Trends and factors associated with anticoagulants use before and after ablation were evaluated. A total of 475 patients with NVAF who received ablation were included in the analysis. Of all, 53.26% of them received antithrombotic therapy preablation. Warfarin was prescribed in 35.26%, with NOACs in 11.37%. Four hundred seventy-three patients received antithrombotic therapy (99.58%) postablation, 236 patients with NOACs (49.68%). CHA2DS2-VASc score, HAS-BLED score, hypertension, diabetes mellitus, and alcohol were independently associated with anticoagulant utilization before catheter ablation. The higher CHA2DS2-VASc score was associated with less frequent prescription of NOACs postablation. The preablation anticoagulation use was still inadequate in China, and CHA2DS2-VASc score was a significant factor influencing the preablation anticoagulant utilization. The utilization rate of NOACs increased significantly postablation, especially for dabigatran, which implied that more physicians prefer to prescribe NOACs for NVAF patients after ablation in our country and may be attributed to the aspects such as ease of NOAC use but also possibly the greater safety and efficacy. Furthermore, the physicians may reluctant to use NOACs for high stroke risk atrial fibrillation patients after catheter ablation.

Abstract
Women with chronic hepatitis B should maintain nucleotide analogue treatment to prevent disease progression during pregnancy. The aim of this study was to prospectively evaluate the efficacy and safety of telbivudine used throughout pregnancy for preventing hepatitis B virus (HBV) mother-to-child transmission (MTCT). From January 2012 to June 2014, women who were receiving telbivudine therapy and became pregnant were enrolled in group A at 28 weeks of gestation. Pregnant women with an HBV DNA level >106 IU/mL were enrolled in either group B (telbivudine started at 28 weeks of gestation) or group C (control group without treatment). MTCT was defined as infants who were positive for serum hepatitis B surface antigen at 7 months after birth. There were 41, 179 and 177 pregnant women (397 infants) enrolled in groups A, B and C, respectively. The HBV DNA load at 28 weeks of gestation and delivery was 1.50 ± 0.62 vs 1.45 ± 0.61, 8.05 ± 0.37 vs 4.24 ± 0.89 and 7.94 ± 0.62 vs 7.86 ± 0.73 log10 IU/mL in groups A, B and C, respectively. The rate of MTCT in group C was 4.60%, which was significantly higher than the rates in groups A and B (0% and 0.6%, respectively) (P = .043). The difference between group A and group B was not significant. The rates of neonatal congenital abnormalities were 2.4%, 0.6% and 2.3% in groups A, B and C, respectively, and there were no significant differences (P = .140). Telbivudine used throughout pregnancy may be safe and effective for mothers and infants, but it may not enhance the efficacy of an HBV MTCT block compared with treatment starting at 28 weeks of gestation (NCT02253485).

Abstract
Variants of cancer susceptibility genes other than BRCA1/2 have been proved to be associated with increased risks of breast cancer. This study was performed to investigate the spectrum and prevalence of mutations in 10 cancer susceptibility genes in paired tumor/normal tissues of 292 unselected Chinese breast cancer patients. We performed an analysis of germline and somatic variants in ATM, CDH1, CHEK2, ESR1, GATA3, MAP3K1, MSH2, PALB2, RB1 and STK11 genes by integrating microfluidic PCR-based target enrichment and next-generation sequencing technologies. In total, 3 germline and 25 somatic deleterious mutations were found among 27 patients (9.25%), and 17 of them were novel mutations. Most deleterious mutations were prevalent in luminal A invasive breast cancer (P = .014). We also observed 83 variants of uncertain significance (VUS) in 100 patients (34.25%), 23 of which were predicted to be deleterious by in silico prediction programs (MetaSVM and MetaLR). VUS carriers had higher positive rate of lymph node metastasis than non-carriers (P = .008) and were predominantly present in ER+ tumors (P = .018). Our findings would enhance the understanding of the molecular mechanisms of breast cancer in Chinese population.

Abstract
There are little data on the timing of initiating lamivudine therapy for preventing transmission of hepatitis B in highly viremic mothers. Between May 2008 and January 2015, we retrospectively enrolled mothers with HBV DNA >6 log10 copies/mL who received lamivudine during pregnancy, and we compared them to untreated mothers. The primary measurement was the vertical transmission rate. The secondary outcomes were the mothers' and infants' safety. Among 249 consecutive mothers enrolled, 66 and 94 received lamivudine during the second and third trimesters, respectively, and 89 were untreated. At delivery, maternal mean HBV DNA levels were significantly lower in mothers who received lamivudine (4.45 log10; vs 7.16 log10 copies/mL; P<.001). Lamivudine treatment was well tolerated. However, early treatment during the second trimester did not significantly increase the percentage of mothers achieving HBV DNA levels of <6 log10 copies/mL compared to those treated during the third trimester (98.5% vs 94.7%; P=.40). At the age of 28 weeks, the vertical transmission rates were significantly lower in the lamivudine-treated mothers vs in the untreated mothers (0% [0/160] vs 5.62% [5/89]; P<.001), but the rates were similar when comparing the two subgroups treated with lamivudine (0% [0/66] vs 0% [0/94], P>.05). The birth defect rates and mothers' and infants' adverse events were similar among the groups. Lamivudine treatment initiated in the second or third trimester for mothers with HBV DNA levels below 9 log10 copies/mL was equally safe and effective in preventing vertical transmission. Thus, lamivudine should be deferred until the third trimester to minimize foetal exposure and drug resistance.

Abstract
Influenza A virus (IAV) infection induces a strong immune response and regulates the expression of many host proteins. The collagen triple helix repeat containing 1 (CTHRC1) protein is a secreted protein that exhibits increased expression during the viral infection process. However, the regulatory function of IAV on CTHRC1 expression is obscure. In this study, we investigated the effect of IAV on CTHRC1 expression and its regulatory mechanism. A total of 106 serum specimens from healthy people and 80 serum specimens from patients infected with IAV were collected. The CTHRC1 levels in the sera from the IVA patients and healthy individuals were measured using an enzyme-linked immunosorbent assay (ELISA), and the differences were statistically analysed. A549 cells were infected with the IAV or delNS1 virus. Additionally, A549 cells were cotransfected with a eukaryotic non-structural NS1 protein gene expression plasmid and the CTHRC1 gene promoter reporter plasmid (pCTHRC1-Luc), and, the luciferase activities were assessed. The CTHRC1 mRNA and protein expression were detected using reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting, respectively. The serum CTHRC1 level was significantly higher in the IAV patients than in the healthy individuals. IAV upregulated the CTHRC1 mRNA and protein expression. The non-structural NS1 protein specifically activated CTHRC1 gene promoter activity and upregulated CTHRC1 mRNA and protein expression. The activation function had a dose-dependent effect, indicating that influenza virus upregulated CTHRC1 expression through its NS1 protein.

Abstract
Toll-like receptors (TLRs) are a family of pattern recognition receptors involved in cardiovascular diseases. Notably, numerous studies have demonstrated that TLR4 activates the expression of several of pro-inflammatory cytokine genes that play pivotal roles in myocardial inflammation, particularly myocarditis, myocardial infarction, ischemia-reperfusion injury, and heart failure. In addition, TLR4 is an emerging target for anti-inflammatory therapies. Given the significance of TLR4, it would be useful to summarize the current literature on the molecular mechanisms and roles of TLR4 in myocardial inflammation. Thus, in this review, we first introduce the basic knowledge of the TLR4 gene and describe the activation and signaling pathways of TLR4 in myocardial inflammation. Moreover, we highlight the recent progress of research on the involvement of TLR4 in myocardial inflammation. The information reviewed here may be useful to further experimental research and to increase the potential of TLR4 as a therapeutic target.

Abstract
371 Background: Sonidegib (LDE225) is a potent, selective, and orally bioavailable inhibitor of smoothened receptor that demonstrated preclinical activity in combination with gemcitabine (GEM). Here, we present data from a phase 1b trial of sonidegib in combination with GEM in patients (pts) with pancreatic adenocarcinoma (PA). Methods: Pts with histologically or cytologically confirmed, locally advanced, or metastatic PA who had not been treated previously or had progressed despite prior chemotherapy (other than GEM) were included in the study. Dose escalation started with sonidegib 400 mg, once a day, in combination with GEM 1000 mg/m2 IV infusion on days 1, 8, and 15 of a 28-day cycle. Results: A total of 18 pts were enrolled (9 pts each the in dose escalation and dose expansion phases). Pts discontinued the study because of disease progression (n = 11, 61.1%), consent withdrawal (n = 3, 16.7%), administrative problems (n = 3, 16.7%), and grade 3 or 4 blood creatine kinase (CK) elevation (n = 1, 5.6%). Three of 9 pts in dose escalation phase experienced dose-limiting toxicities during the first 8 weeks including grade 3 mucositis (n = 1), grade 3 CK elevation (n = 1), and grade 3 aspartate aminotransferase elevation (n = 1). Drug-related adverse events (AEs) of all grades were reported in 14 pts (77.8%) and grade 3 or 4 AEs were reported in 10 pts (55.6%). The most commonly reported AEs were anemia and nausea. No pharmacokinetic (PK) interaction was observed. Based on considerations of the statistical model, clinical assessment of safety, tolerability, PK, and pharmacodynamic results, maximum-tolerated dose and recommended dose were established as 400 mg of sonidegib in combination with the fixed standard dose of GEM (1000 mg/m2).The objective response rate was 11.1% and the median progression-free survival (PFS) was 4.9 months. Conclusions: The combination of sonidegib and GEM was generally well tolerated with moderate activity. Although no formal comparison can be made due to small sample size of this study, this combination provided a median PFS comparable to the current standard of care without conferring any additional clinical benefit. Clinical trial information: NCT01487785.

Abstract
Hypoxia-inducible factor-2 alpha (HIF-2α) has been shown to regulate cell stemness, although the expression and effects of HIF-2α in lung cancer stem cells remained unclear. This study investigated HIF-2α expression in lung cancer stem cells, as well as the relationship between HIF-2α expression and radioresistance in lung cancer cells. Stem-like cells (CD133(+)) in the non-small-cell lung cancer cell line A549 were enriched by serum-free culture conditions, and CD133(+) cells were sorted via fluorescence-activated cell sorting. A549 cells were treated with middle-infrared radiation, and the level of HIF-2α expression was determined by a quantitative polymerase chain reaction assay and western blot analysis. The level of HIF-2α expression in tissue sections from 50 cases of clinically confirmed non-small-cell lung cancer was determined via immunohistochemical analysis, and its correlation with prognosis after radiotherapy was analyzed. HIF-2α levels in CD133(+) cells were significantly higher than those in CD133(-) cells (P = 0.032). However, after radiation treatment, these levels were significantly upregulated in both CD133(+) and CD133(-) cells (P = 0.031 and P = 0.023, respectively). After irradiation, the proportions of apoptotic, dead, and autophagic CD133(+) A549 cells were considerably lower than those of CD133(-) A549 cells (P < 0.05). Furthermore, the recovery of carcinoembryonic antigen to pre-radiation levels was more rapid in lung cancer patients with high levels of HIF-2α expression, and these patients had shorter survival times (P = 0.018). HIF-2α is highly expressed in lung cancer stem cells, which may lead to radioresistance. In conclusion, HIF-2α is a potential prognostic marker for lung cancer.

Abstract
Background Wilms tumor (WT) is an embryonic kidney cancer, for which histone acetylation might be a therapeutic target. LBH589, a novel targeted agent, suppresses histone deacetylases in many tumors. This study investigated the antitumor activity of LBH589 in SK-NEP-1 and G401 cells. Methods SK-NEP-1 and G401 cell growth was assessed by CCK-8 and in nude mice experiments. Annexin V/propidium iodide staining followed by flow cytometry detected apoptosis in cell culture. Gene expressions of LBH589-treated tumor cells were analyzed using an Arraystar Human LncRNA Array. The Multi Experiment View cluster software analyzed the expression data. Differentially expressed genes from the cluster analyses were imported into the Ingenuity Pathway Analysis tool. Results LBH589 inhibited cell proliferation of SK-NEP-1 and G401 cells in a dose-dependent manner. Annexin V, TUNEL and Hochest 33342 staining analysis showed that LBH589-treated cells showed more apoptotic features compared with the control. LBH589 treatment inhibited the growth of SK-NEP-1 xenograft tumors in nude mice. Arraystar Human LncRNA Array analysis of genes and lncRNAs regulated by LBH589 identified 6653 mRNAs and 8135 lncRNAs in LBH589-treated SK-NEP-1 cells. The most enriched gene ontology terms were those involved in nucleosome assembly. KEGG pathway analysis identified cell cycle proteins, including CCNA2, CCNB2, CCND1, CCND2, CDK4, CDKN1B and HDAC2, etc. Ingenuity Pathway Analysis identified important upstream molecules: HIST2H3C, HIST1H4A, HIST1A, HIST1C, HIST1D, histone H1, histone H3, RPRM, HSP70 and MYC. Conclusions LBH589 treatment caused apoptosis and inhibition of cell proliferation of SK-NEP-1and G401 cells. LBH589 had a significant effect and few side effects on SK-NEP-1 xenograft tumors. Expression profiling, and GO, KEGG and IPA analyses identified new targets and a new “network” of genes responding to LBH589 treatment in SK-NEP-1 cells. RPRM, HSP70 and MYC may be important regulators during LBH589 treatment. Our results provide new clues to the proapoptotic mechanism of LBH589.

Abstract
OBJECTIVE To examine whether transcutaneous electric nerve stimulation at acupoints (Acu-TENS) improved the biochemical and physical indices of patients with type 2 diabetes mellitus (T2DM). METHODS Ninety subjects with T2DM were divided randomly into a control group (n = 30), aerobic exercise group (n = 30), or Acu-TENS group (n = 30). In addition to conventional diabetes drug treatment, patients in the Acu-TENS group received acupoint stimulation, the aerobic exercise group engaged in walking exercises, and the control group was given sham electrical stimulation. All groups were treated for 30 min for each session and five times a week for 2 months. The indices of glycosylated hemoglobin, 2 h postprandial glucose, fasting serum insulin, triglyceride, total cholesterol, and body mass index were assessed at pre-treatment, post-treatment, and follow-up, which was 2 months after treatment. RESULTS The indices of the control group were not changed (P > 0.05) at the three time points. At the pre-treatment measurement, there were significant differences (P > 0.05) in indices among the three groups. At post-treatment, each index of the two groups was lower than that of the control group (P < 0.05), and improved in comparison with the pre-treatment measurement (P < 0.05). In follow-up, each index of the aerobic exercise group and Acu-TENS group increased, but was still decreased compared with the pre-treatment value (P < 0.05), excluding body mass index. CONCLUSION Acu-TENS could improve the state of patients with T2DM and be used as a therapy in clinical application.

Abstract
Orally administered nucleus(t)ide analogues (NA) have brought about a simple, safe and effective therapeutic approach for chronic hepatitis B (CHB). However, treatment duration is long and some female patients become pregnant during treatment. In recent years, there have been gradually increasing reports on the safety of telbivudine (LdT) treatment for chronic hepatitis B virus (HBV) infection in the third trimester of pregnancy to block mother-to-infant transmission (MTIT) of HBV; however, the safety of LdT treatment for chronic HBV infection for the entire pregnancy has not been reported. The aim of the present study was to evaluate the safety of LdT treatment for chronic HBV infection for the entire pregnancy and provide a reference for HBV-infected fertile women on how to block MTIT of HBV. Eighty-six pregnant women who received LdT treatment either before or in early pregnancy were enrolled in the study. Adverse events were prospectively observed for the entire pregnancy and perinatal period, and short-term and long-term follow-up of infants was conducted, monitoring the abnormalities of infants and blocking rate of MTIT with LdT treatment. Eighty-six pregnant women treated with LdT had a total of 89 pregnancies: 6 (6.7%) had early embryonic death or spontaneous abortion, 1 (1.1%) had ectopic pregnancy and three had a second pregnancy after initial abortion. Fifty-one mothers completed pregnancy: one had induction of labour at 24 weeks of pregnancy for cleft lip and palate of the foetus and 50 delivered 52 full-term live infants. One infant had right ear accessories, and the total occurrence of congenital abnormality was 3.8%. Thirty-nine infants were followed up for more than 6 months and completed all examinations for MTIT. None of the infants were HBsAg positive, resulting in a 100% success rate of blocking MTIT. All mothers maintained good liver function during the third trimester of pregnancy; 86% maintained complete virological response (HBV DNA <500 copies/mL) prior to delivery, and none developed progression of liver disease. Factors leading to increased adverse effects and drug resistance were not found. LdT treatment is safe and effective in chronic HBV-infected pregnant mothers for the entire pregnancy.

Abstract
A new derivative of polyamidoamine and polyethylenimine, G2.5-PEI 423 or G1.5-PEI 423, is prepared by an amidation reaction of PAMAM G2.5 or PAMAM G1.5 using PEI 423. The polycations show a great ability to combine with pDNA to form complexes, which protect the pDNA from nuclease degradation. The polymers display stronger buffer capacity and lower cytotoxicity. The complexes have particle sizes of 120-180 nm and zeta potentials of 20-40 mV. The G2.5-PEI 423 complexes display much higher transfection efficiencies than PAMAM G5 and Lipo-2k, and the G1.5-PEI 423 complexes display higher transfection efficiencies than PAMAM G4 and PEI-25k. The complexes possess better serum-resistant capacity. The G2.5-PEI 423 has a great potential to be used as a serum-resistant gene vector.

Abstract
Human leucocyte antigen (HLA) genetic characteristic of different ethnic minorities would be useful for tracing the origin of modern human HLA matching in transplantation and disease associations. In this study, we reported HLA-A, -B, -C and -DRB1 alleles and haplotypes in the Bulang and Hani populations of southwestern China using a high-resolution polymerase chain reaction-Luminex (PCR-Luminex) typing method. A total of nine HLA-A, 22 HLA-B, 13 HLA-C and 18 HLA-DRB1 alleles were identified in the Bulang population, and 11 HLA-A, 25 HLA-B, 14 HLA-C and 19 HLA-DRB1 alleles were in the Hani population. Compared with other populations, the predominant A*1101-B*1502-DRB1*1202 haplotype in the Bulang and Hani populations was also common in Jinuo, Wa, Dai, Maonan and Vietnamese populations. The distribution of HLA genes indicate that Bulang and Hani populations belong to the Southeast Asia group and they have maintained their original genetic characteristics and kept a long genetic distance from other populations owing to founder effects and subsequent geographic isolation. In addition, the close relationship among ethnic groups in Yunnan province and the Thai and Vietnamese populations were confirmed, whereas the Mon-Kmer-speaking populations shared other common HLA alleles and haplotypes compared with other linguistic groups.

Abstract
We show how dissipative dynamics can give rise to pairing for two-component fermions on a lattice. In particular, we construct a parent Liouvillian operator so that a BCS-type state of a given symmetry, e.g., a d-wave state, is reached for arbitrary initial states in the absence of conservative forces. The system-bath couplings describe single-particle, number-conserving and quasilocal processes. The pairing mechanism crucially relies on Fermi statistics. We show how such Liouvillians can be realized via reservoir engineering with cold atoms representing a driven dissipative dynamics.

Abstract
It is hard to stabilize the p-wave superfluid state of cold atomic gas in free space due to inelastic collisional losses. We consider the p-wave Feshbach resonance in an optical lattice, and show that it is possible to have a stable p-wave superfluid state where the multiatom collisional loss is suppressed through the quantum Zeno effect. We derive the effective Hamiltonian for this system, and calculate its phase diagram in a one-dimensional optical lattice. The results show rich phase transitions between the p-wave superfluid state and different types of insulator states induced either by interaction or by dissipation.

Abstract
In this study, polymorphisms of human leukocyte antigen (HLA) class I (A, B, and Cw) and class II (DRB1) loci were analyzed in an isolated Han population living in Fengyandong in the Yunnan province of Southwest China (FYDH) using a high-resolution polymerase chain reaction-Luminex typing method. A total of 13 A, 26 B, 15 Cw, and 23 DRB1 alleles of HLA were found in FYDH. The frequencies of A*1101, A*0207, A*2402, B*4601, B*1502, Cw*0102, Cw*0801, DRB1*0901, and DRB1*1202 were >10%. The following haplotypes were common with frequencies >5%: three A-B, four Cw-B, two B-DRB1, two A-B-DRB1, three A-B-Cw, two B-Cw-DRB1, and two A-B-Cw-DRB1 phylogenetic tree and multidimensional scaling analysis based on HLA-A, -B, and -DRB1 allele frequencies of 18 Han populations suggested that FYDH was an isolated Han population, but the analytic result also provided a suggestion that FYDH was genetically related to Chinese Southern Han. According to the characteristics of the HLA allele and haplotype distributions and significantly reduced allelic and haplotypic diversity in FYDH, we deduced that genetic drift and/or selection and subsequent geographic isolation had influenced the distribution characteristics of the HLA gene in FYDH. In addition, significantly reduced allelic and haplotypic diversity in FYDH makes it an ideal homogenous population and very useful model for future investigations of issues related to immunogenetic diseases in the Han population.
