Abstract
The inoculation of S. cerevisiae can address the excessive acidity in Suanyu, but its influence on the microbial community structure has not been documented. In this study, the microbiota succession, and metabolites of Suanyu with the inoculation of acid-reducing S. cerevisiae L7 were explored. The findings revealed that the addition of S. cerevisiae L7 elevated the pH, and decreased the microbial α-diversity. In Suanyu, the dominant bacterial genera were Lactiplantibacillus and Bacillus, while the dominant fungal genera were Meyerozyma and Saccharomyces. Following the inoculation of S. cerevisiae L7, the relative abundance of Lactiplantibacillus decreased from 21 % to 13 %. Meanwhile, the growth of fungi such as Meyerozyma and Candida was suppressed. The rise in Saccharomyces had a significant impact on various pathways related to amino acid and carbohydrate metabolism, causing the accumulation of flavor compounds. This study sheds more lights on the methods for manipulating microbial community structure in fermented food.

Abstract
Gastric ulcers are worrying, and their worsening conditions may result in bleeding in the internal lining of the stomach. The problem is annoying, and both patients and professionals are still not satisfied with the available treatment options. Hesperidin, a flavonoid molecule with potent anti-inflammatory and antioxidant effects, can work like witchcraft to repair gastric ulcers and preserve the stomach lining. Here, we employed a strategy that involved covering the surface of the nano-lipid carriers (NLCs) with sericin before encasing the hesperidin within (Se-He-NLC). Sericin, a biodegradable polymer increases the muco-adhesion with stomach lining and deployment of hesperidin in controlled manner. Se-He-NLCs were physico-chemically characterized for drug loading, encapsulation, particle size, morphology, drug release, chemical stability, and chemical bonding. The nanocarriers showed first order drug release in a controlled manner. Se-He-NLCs showed better in vitro permeation and ex vivo mucoadhesion, thereby by promoting the in vivo bioavailability. Se-He-NLCs also promoted the reduced glutathione (GSH) and glutathione-S-transferase (GST) levels by 2.24- and 1.61-folds, respectively in the stomach lining, and also the regulation of superoxide dismutase (SOD) and catalase (CAT) activities parallel to the control group. In addition, tissues lipid hydroperoxides (LOOH) and myeloperoxidase (MPO) activity were reduced significantly with Se-He-NLCs administration. Se-He-NLC therapy of stomach ulcers in vivo demonstrated better binding ratio and ulcer healing potential. This approach reveals huge capacity for delivering therapies to treat gastric ulcers based on the clinical significance of sericin coated hesperidin nanocarriers in gastric ulcer treatment.

Abstract
Water scarcity as well as social and economic damages caused by the increasing amounts of non-revenue water in the water distribution networks (WDNs) have been prompting innovative solutions. A great deal of potable water is wasted due to leakage in the WDNs all over the world. Hence, various leak detection approaches have been explored, including the promising application of acoustic devices. Exploiting the benefits of technological advances in acoustic devices, signal processing, and machine learning (ML), this study aimed to develop a sophisticated system for leak detection in WDNs. Different from laboratory-based studies, this study was conducted on real WDNs in Hong Kong and lasted for about two years. Utilizing acoustic emissions acquired using wireless noise loggers, various ML algorithms were explored to develop inspection models for in-service and buried WDNs. ML classification algorithms can identify patterns in the acquired signals for leak and no-leak statuses. Thus, a combination of features describing acoustic signals in time and frequency domains was utilized to facilitate the development of ML models. Separately for metal and non-metal WDNs, ten well-known ML algorithms were used to develop leak detection models. The validation results demonstrate the promising application of noise loggers and ML for leak detection in real WDNs. Support Vector Machine (SVM), Artificial Neural Network (ANN), and Deep Learning (DL) leak detection models demonstrated a largely stable performance and a very good accuracy, particularly for new unlabelled cases.

Abstract
BACKGROUND Inhalation preparation involves liquid or solid raw materials for delivering to lungs as aerosol or vapor. The liquid preparation for nebulizer is effective for convenient use and patient compliance and it has been extensively used in the treatment of clinical lung diseases. Clinical staff often mixes the compound ipratropium bromide with beclomethasone propionate and budesonide inhaler but reference values of inhalants for clinical use need to be established for simplifying the operation procedure. The high-performance liquid chromatography (HPLC) method of compound ipratropium bromide solution, beclomethasone propionate suspension and budesonide suspension after mixed atomization was studied. METHODS The specificity, linearity, recovery (accuracy), precision and stability of compound ipratropium bromide, beclomethasone propionate and budesonide were tested to verify the developed liquid phase method. RESULTS The developed liquid phase method had high specificity, linear R2≥0,999, recovery (accuracy) RSD (relative standard deviation) less than 2%, precision RSD less than 2,0%, and stability RSD less than 2,0%. CONCLUSION The liquid phase methodology developed in this study can be used for the determination of compound ipratropium bromide mixed with beclomethasone propionate and budesonide. The current methodology can also be used to provide a reference for the determination of its content after mixing, and further data support for its clinical medication.

Abstract
BACKGROUND The aim of this study was to assess use of lncRNAs as biomarkers in serum and aqueous humor of patients with diabetic macular edema (DME). MATERIAL AND METHODS Optical coherence tomography and fundus photography were used to analyze the retinal features of the patients. RT-qPCR was used to analyze the differential expression of lncRNA snhg5 in patients who have idiopathic macular hole (MH), DME, or refractory DME. The relationship between SNHG5 and the clinical characteristics of the patients was analyzed. The effect of SNHG5 on the hyperplasia and apoptosis of human retino-microvascular endothelial cells (HRMECs) and its mechanism were analyzed in vitro. RESULTS Patients with idiopathic MH developed retinal nerve epithelium rupture and retinal fundus thickening, and patients with DME or refractory DME showed significant macular edema with hemorrhaging. The refractory DME patients improved after treatment but still showed significant macular edema and multiple laser scarring. SNHG5 expression was not only low in the atrial fluid and plasma in DME patients, but also lower in the refractory DME group compared to the idiopathic MH patients. SNHG5 expression in the aqueous humor and plasma was negatively correlated with disease duration, body mass index, and levels of fasting blood glucose, glycated hemoglobin, proteinuria, and glycosuria. In the in vitro experiments, SNHG5 expression was significantly downregulated in high glucose-induced HMECs. After SNHG5 overexpression, cell proliferation, angiogenesis, and VEGF-A protein levels were distinctly downregulated. CONCLUSIONS SNHG5 correlates with the development of DME and is a potential target for therapy.

Abstract
BACKGROUND Lymph node (LN) involvement is a critical prognostic factor in patients with gallbladder carcinoma (GBC). Controversy exists regarding optimal categorization of nodal metastasis status, including anatomical location of positive nodes (AJCC 7th N staging), number of metastatic lymph nodes (NMLN), log odds of metastatic LNs (LODDS), and lymph node ratio (LNR). METHODS Patients who underwent curative-intent resection for GBC from six Chinese tertiary hospitals between 2008 and 2013 were analyzed retrospectively. The relative discriminative abilities of the different LN staging systems were assessed by different models including the tree-augmented naïve Bayesian (TAN) model, Cox proportional hazards regression model, and binary logistic regression model. RESULTS A total of 226 patients were involved in this cohort. Based on the TAN model and composite importance measures, the most important factor affecting the prognosis in the different LN staging systems was NMLN. Among the four TAN models which were built with 4 metastatic LN markers and baseline variables, the accuracy of the NMLN-based prognostic model was 88.15%, higher than 7th N staging (86.44%), LNR (87.34%), and LODDS (85.19%). The Cox model based on NMLN (C-index: 0.763, AIC: 1371.62) had a higher fitness than the others (7th N staging C-index: 0.756, AIC: 1375.51; LNR C-index: 0.759, AIC: 1378.82; LODDS C-index 0.748, AIC: 1390.99). The AUCs of different staging binary logistic regression models were NMLN (0.872), LNR (0.872), 7th N staging (0.869) and LODDS (0.856), respectively. CONCLUSIONS NMLN was the optimal LN staging system in evaluating prognosis of GBC.

Abstract
Plant hormones participate in the regulation of plant growth, and have significant physiological activities. Secondary metabolites are important raw materials of pharmaceutical and chemical industry, which have attracted extensive attention due to their economic and medicinal value. With the development of biotechnology, plant hormones have played an important role in regulating the synthesis of secondary metabolites. This paper mainly introduces the synthesis pathway, signal transduction mechanism and regulation of secondary metabolites of auxin, cytokinin, gibberellin, abscisic acid, ethylene, brassinosteroids and methyl jasmonate in plants. Researching the accumulation of secondary metabolites from a micro aspect is helpful to better understand the formation of plant hormones and their development in the process of secondary metabolism. In additionally, it provides a reference for the rational utilization of plant hormones and the scientific and efficient improvement of the production of secondary metabolites in plants.

Abstract
T-2 toxin at low concentrations can induce ROS accumulation and modulate host resistance in plants. NOX plays crucial roles in ROS production and is regulated by Ca2+via direct binding to EF-hand motifs. In this study, the effect of EGTA (Ca2+ chelating agent) on the expression and enzymatic activity of NOX, as well as the activities and corresponding gene expressions involved in ROS metabolism and cell membrane integrity, were investigated in treated slices. Results indicated that EGTA treatment significantly affected gene expression and activity of NOX, and reduced ROS accumulation and cell membrane integrity and the enzymatic activities and gene expression involved in ROS metabolism when exposed to treatment. The addition of exogenous Ca2+ restored the initial relative transcript abundance, ROS accumulation and their activities. Results suggest that Ca2+ affected by EGTA plays a crucial role in NOX activity regulation, ultimately affecting ROS metabolism in slices induced by T-2 toxin.

Abstract
PurposeThis study aims to revisit the corporate social and environmental disclosure (CSED) practices of Pakistani companies using unique CSED index which measures the CSED through three dimensions such as theme, news type and nature of information. In addition, the effect of board composition, ownership structure and corporate characteristics on CSED was tested through performing multiple regression analysis.Design/methodology/approachFor this purpose, data were collected from annual reports of top 120 companies’ selected based on market capitalization for three years period of 2013-2015.FindingsBased on the descriptive statistics, the results found that overall level of CSED in Pakistan is moderate. However considering CSED using three dimensions, the results demonstrate that highest level of disclosure on the basis of theme is reported in terms of human resource category as compared to other categories where, as in terms of news type and nature of information, analysis shows that companies in Pakistan feel resistant to disclose bad news, monetary and non-monetary aspect of CSED information. Using multiple regression analysis, the results found that all the variables have hypothesized relationship with CSED except government and institutional ownership. The variables such as chairman as non-executive director, board diversity, appointment of independent director as audit committee chairman, CSR committee, industry type and firm size are found to have significant influence on the CSED practices in Pakistan.Research limitations/implicationsThese results imply that the CSED phenomenon is still lacking behind. Under individual categories of CSED, descriptive statistics found that environment is still not a matter of concern for companies operating in Pakistan. In addition, the results demonstrate that CSED practices are only performed by very few companies in Pakistan based on standard deviation. In addition, appointment of non-executive and independent director as chairman of board and audit committee and representation of foreigners on the board should be encouraged in order to improve CSED practices in Pakistan.Originality/valueThis study contributes to the existing literature in developing country like Pakistan through using unique CSED index and also making comparison of financial versus non-financial sectors. The author suggests that regulatory authorities in Pakistan must take reasonable steps to make the company’s operations environment-friendly.

Abstract
OBJECTIVE This study investigated the effects of calcium on fluorosis-induced impairment in learning and memory of offspring rats. Methods Seventy-five newly weaned female Sprague-Dawley (SD) rats were randomly divided into five groups as follows: Control group (Control) drank tap water, and ate the normal diet (calcium content of 0.79%); fluoride group (F) drank 100 mg/L NaF solution, and ate the normal diet; low calcium group (LCa) drank tap water, and ate the low calcium diet (calcium content of 0.063%); low calcium fluoride group (F+LCa) drank 100 mg/L NaF solution, and ate the low calcium diet; high calcium fluoride group (F+HCa) drank 100 mg/L NaF solution, and ate the high calcium diet (calcium content of 7%). After exposing rats to fluoride for three months, male and female rats were mated and 14 and 28 days old offspring were obtained as experimental subjects. Examinations determined the submicroscopic parameters of the synaptic interface and expression levels of specific proteins: doublecortin (DCX) and synaptophysin (p38). RESULTS (1) High fluorosis significantly reduced synapse density, length of synaptic active zone, thickness of postsynaptic density, and led to abnormal changes in the structural parameter of synaptic gap width, which was significantly reduced or increased. High dietary calcium significantly reversed the abnormal changes in structural parameters, and low calcium aggravated these variations. (2) Dietary calcium resulted in nonsignificant effect on expression levels of DCX and p38. CONCLUSION The results suggested that dietary calcium significantly affected hippocampal synaptic plasticity of offspring of mothers exposed to water fluorosis, but its molecular mechanism may not be related to the expression of DCX and p38 in the brain. The findings also demonstrate the important effects of maternal exposure to water fluorosis on offspring brain functions before water improvement.

Abstract
Mycoplasma bovis (M. bovis) is an important pathogen of cattle. An attenuated live vaccine has recently been developed by this laboratory. However, an effective assay for the differentiation of infected from vaccinated animals (DIVA) is still lacking. Therefore, a comparative immunoproteomics study of the membrane and membrane associated proteins (MAPs) of M. bovis HB0801 and its attenuated strain (M. bovis-150) was aimed to identify potential antigens for DIVA assay. Triton-X-114 fractionated liposoluble proteins of both the virulent and attenuated strains were separated with 2-DE and proteins reacting with sera against the virulent M. bovis strain were detected by MS. A total of 19 differently expressed proteins were identified by MS, among them twelve proteins were detected by MALDI-TOF MS and seven antigenic proteins were identified by short-gun LC-MS/MS. Furthermore, these findings were confirmed at mRNA level by qRT-PCR. The results demonstrated that a putative lipoprotein encoded by functionally unknown gene Mbov_0730 (MbovP730) is a sensitive and specific antigen for DIVA assay. MbovP730 is absent in M. bovis-150 confirmed with Western blot assay and also didn't cross-react with other antisera against common pathogens including infectious bovine rhinotracheitis virus and bovine viral diarrhea virus by iELISA. Thereby rMbovP730-based iELISA was established. For clinical samples, this ELISA provided a sensitivity of 95.7% (95% CI: 90.4%, 98.2%) and specificity was 97.8% (95% CI: 88.4%, 99.6%). Antisera from vaccinated calves (n = 44) were found negative with rMbovP730 based iELISA, while positive with assays based on whole cell proteins of M. bovis-150 and M. bovis HB0801, respectively. In conclusion, this study identified the differential antigen MbovP730 between virulent and attenuated strains and established rMbovP730-based iELISA as a new DIVA method.

Abstract
Nanocellulose reinforced poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) composites were prepared using melt compounding. The effects of nanocellulose types (CNCs and CNFs) and nanocellulose content (1, 2, 3, 4, 5, 6 and 7wt%) on the crystallization, thermal and mechanical properties of PHBV composites were systematically compared in this study. The thermal stability of PHBV composites was improved by both CNCs and CNFs. CNFs with a higher thermal stability leaded to a higher thermal stability of PHBV composites. Both CNCs and CNFs induced a reduction in the crystalline size of PHBV spherulites. Furthermore, CNCs could act as a better nucleating agent for PHBV than did CNFs. CNCs and CNFs showed reinforcing effects in PHBV composites. At the equivalent content of nanocellulose, CNCs led to a higher tensile modulus of PHBV composites than did CNFs. 1wt% CNCs/PHBV composites exhibited the most optimum mechanical properties.

Abstract
The fast and full range measurements of ellipsometric parameters ψ and Δ using a 45° dual-drive symmetric photoelastic modulator (PEM) are proposed. The PEM operates in a pure traveling modulation mode with a constant retardation magnitude and the modulation axis performing circular motion. A field programmable gate array is used to control the PEM and fulfill the data processing. The parameters sin 2ψ sinΔ, sin 2ψ cosΔ, and sin 2ψ can be measured simultaneously, providing accurate measurements of ψ and Δ over the full range. The experimental results show that the repeatability and sensitivity of this system are at 10-3°, and the data acquisition rate is 1 ms/point.

Abstract
Enterprise Simulative Games are commonly introduced to students at universities as means of exposing them to real world business challenges. They are designed to challenge the students’ previously acquired knowledge and expertise. They aim to improve the students’ general business and enterprise management skills. Success in the game is a reflection of effective “constant” interactions among the students in the groups as well as the proper use of the diverse knowledge possessed by the members and/or disseminated by the CEO and the lecturers. In addition, effective sharing of what they know is integral to winning over the other groups. This is essential for their success in the game. It is anticipated that the increase in the sharing of knowledge during the game activities increases the groups’ chances of having competitive edge over their peers. In this research, we investigated the effects of organisational context, motivational factors and personal characteristics on the knowledge sharing during the students’ participation in the simulative games. Based on data analysis methods, the research findings demonstrated that these factors have positive effects on the knowledge shared among group members in groups. The paper also found that individual characteristics increase the knowledge sharing if it is coupled with motivational factors rather than individual characteristics alone.

Abstract
The soil water supply is the main factor that limits dryland crop production in China. In a three-year field experiment at a dryland farming experimental station, we evaluated the effects of various straw mulch practices on soil water storage, grain yield, and water use efficiency (WUE) of winter wheat (Triticum aestivum). Field experiments were conducted with six different mulch combinations (two different mulch durations and three different mulch amounts): high (SM1; 9000 kg ha−1), medium (SM2; 6000 kg ha−1), and low (SM3; 3000 kg ha−1) straw mulch treatments for the whole period; and high (SM4), medium (SM5) and low (SM6) straw mulch treatments during the growth period only, where the control was the whole period without mulch (CK). Throughout the whole growth period of the three-year experiment, the average soil water content in the 0–200 cm soil layer increased by 0.7–22.5% compared with CK, while the WUE increased significantly by 30.6%, 32.7% and 24.2% with SM1, SM2, and SM3, respectively (P < 0.05). The yield increased by 13.3–23.0% when mulch was provided during the growth period, while the WUE increased by 15.2%, 17.2% and 18.0% with SM4, SM5, and SM6, respectively, compared with CK.

Abstract
Background It has been widely demonstrated that the hedgehog pathway is strongly associated with basal cell carcinoma of the skin (NBCCS). To assess potential DNA alterations related to keratocystic odontogenic tumors (KCOTs), we sequenced smoothened (SMO) genes in 12 sporadic KCOTs. Methods Polymerase chain reaction (PCR), capillary electrophoresis and dideoxy chain-termination sequencing were used to examine potential DNA alterations in sporadic KCOTs. Results Five alterations in SMO genes were detected. Four of these mutations consisted of two synonymous and three missense mutations; two of which have not been reported to date (c.T776A, c.T1281G). Conclusions SMO genes may play an important role in the sonic hedgehog (SHH) pathway and could also be responsible for generating KCOTs and NBCCS. However, their influence on SHH signaling remains to be elucidated.

Abstract
Children with MS-LCH that fail to respond to conventional chemotherapy have poor outcomes. HSCT represents a potential salvage approach. It has been applied in over 50 cases in recent years. HSCT can achieve greater disease control than chemotherapy, but it carries a high risk of transplant-related mortality; thus, the haploidentical parental HSCT is used infrequently in pediatric refractory LCH. We report the first successful haploidentical parental HSCT, with no T-cell depletion, in two girls, aged 26 months and five months, with refractory MS-LCH. The mothers were donors with 5/6 and 4/6 HLA matches, respectively. The conditioning regimen included busulfan + cyclophosphamide + etoposide + antithymocyte-globulin ± fludarabine; the GVHD prophylaxis was based on cyclosporine + methotrexate ± mycophenolate-mofetil ± zenapax. In both cases, the stem cells were sourced from peripheral blood and BM, which included CD34+ cells (13.17 × 10(6)/kg and 40.23 × 10(6)/kg, respectively). These patients survived and showed no signs of disease activity in 54- and 44-month post-HSCT follow-ups. Our results indicated that, for patients that fail chemotherapy delivered early in the disease, but do not show organ dysfunction progression, it may be possible to achieve successful haploidentical parental HSCT with a strong myeloablative regimen.

Abstract
Recent theoretical researches reveal that the self-focusing critical power in the fiber waveguide is identical to that in the bulk medium. However, the delivery of peak power much higher than the self-focusing critical power has been demonstrated experimentally in ultra-large-mode-area fiber (ULMAF). And no experimental observation of self-focusing effect has been reported in recent pulsed fiber laser system whose peak power has reached or even exceeded the critical power. In this paper, we try to address this issue by studying the self-focusing length theoretically in the ULMAF which is highly multimode. Nonlinear beam propagation method employing PÁDE(2,2) approximation is applied in the numerical simulation. The results show that the self-focusing length of the fundamental mode is typically a few millimeters which is almost identical to that in the bulk medium. However, the self-focusing length of the summation of numerous modes can be as long as a few meters.

Abstract
PURPOSE Th-cytokines play important roles in dacryoadenitis associated with Sjögren's syndrome (SS). The aims of this study were to (i) investigate whether interleukin (IL)-17, a newly identified Th-cytokine, participates in autoimmune dacryoadenitis of MRL/lpr mice and (ii) examine the relationships among IL-17, IL-4, and interferon (IFN)-γ in these mice. METHODS Three-month-old MRL/lpr mice with lacrimal gland inflammation and 3-month-old control BALB/c mice were used. Frozen sections of lacrimal glands and submandibular lymph nodes were stained with monoclonal antibodies to cytokines IL-17, IL-4, and IFN-γ. Concentrations of IL-17 in serum and 48-h splenocyte culture supernatants were detected by ELISA. RESULTS Marked lacrimal gland inflammation was observed in all MRL/lpr mice but not in any BALB/c control mice. In the lacrimal glands of MRL/lpr mice, the proportions of cells that stained were 5 ± 3% for IL-17, 32 ± 14% for IL-4, and 4 ± 2% for IFN-γ. In the submandibular lymph nodes of MRL/lpr mice, expression of IL-17 and IL-4 was significantly higher than that of IFN-γ, and all three cytokines were significantly higher in MRL/lpr mice than in BALB/c mice. Concentrations of IL-17 in both serum and splenocyte culture supernatants of MRL/lpr mice were elevated compared to BALB/c controls. CONCLUSIONS Since expression of IL-17 is elevated in 3-month-old MRL/lpr mice, we suggest that it plays a role in the pathophysiology of autoimmune dacryoadenitis in these mice.

Abstract
The conversion of frequency modulation to amplitude modulation (FM-to-AM) effect is harmful to the high power laser facility based on the phase modulation technique. The FM-to-AM effect of phase modulation pulse induced by the weak etalon effect in wave plates was investigated theoretically and experimentally. A bulk phase modulator with a modulation frequency of 9.2GHz was employed. The numerical simulation results show that the FM-to-AM effect with a temporal modulation depth of 2.5% and 29.7% on the top of the pulse shape was induced by the weak etalon effect in half-wave plate with thickness of 1mm and residual reflectance ratio of 0.5% for 1 pass and 12 passes respectively. On the same condition, the temporal modulation depth is 3.0% and 23.4% respectively in the experiment. The results are in good agreement with numerical simulation results. To our knowledge, it is the first time to introduce the weak etalon effect in wave plates for a complex phase modulation laser system.

Abstract
This study presents a novel extraction technique, ultrahigh pressure extraction, to obtain major catechins from green tea leaves. The effects of various high pressure level (100, 200, 300, 400, 500, 600 MPa) on the extract are examined. HPLC chromatographic analyses determine the concentration of four major catechins and caffeine. The extraction yields of active ingredients with ultrahigh pressure extraction (400 MPa pressure) for only 15 min were given the same as those of organic solvent extraction for 2h. These excellent results for the ultrahigh pressure extraction are promising for the future separation of active ingredients from traditional Chinese herbal medicine.

Abstract
A new coupling method is proposed for high-power laser-diode-array (LDA) end-pumped large-aperture amplifiers. In this method, stacks in the LDA are distributed on a spherical surface, and a hollow duct is placed after them. Both numerical simulations and experimental research have been done for this method. All results show that high coupling efficiency and uniform pumping field can be obtained simultaneously using this method.

Abstract
Gene therapy with adenoviral vectors is a promising new approach for the treatment of refractory advanced breast cancer. Strategies to restrict adenoviral-mediated therapeutic gene expression are important to avoid harming normal cells. Fatty acid synthase (FAS) is overexpressed in several human cancers. FAS is highly expressed in infiltrating breast cancer tissue, and always associated with malignant phenotypes and poor prognosis. In this study, expression of the FAS was evaluated in three breast cancer cell lines. A 680 bp-FAS promoter was cloned and its transcriptional activity was analyzed in breast cancer cell lines. We made a recombinant adenovirus construct carrying herpes simplex virus thymidine kinase (HSV-TK) driven by human FAS promoter (Ad-FAS-TK) and analyzed its target cytotoxicity in vitro and in vivo against human breast cancer cells combined with prodrug ganciclovir (GCV). The results show that the expression of FAS varies in the three breast cancer cell lines examined (respectively, SK-Br3>MCF-7>MDA-MB-231), but FAS promoter can initiate relative high transcriptional activities in all three kinds of cancer cells while little in normal fibroblast cells. Furthermore, FAS promoter can drive the therapeutic gene in a wider range of human breast cancers than cerbB2 promoter and exhibit a stronger activity than midkine (MK) promoter. Combination of Ad-FAS-TK and GCV treatment exhibited strong-targeted cytotoxic effect on breast cancer cells but showed little activity in normal fibroblast cells. The tumorigenic capability of breast cancer cells treated with Ad-FAS-TK/GCV was completely inhibited in vitro and in vivo assays. In conclusion, adenoviral-mediated suicide gene therapy controlled by tumor associated-FAS promoter can induce specific cytotoxic effect on human breast cancer cells in vitro and in vivo. So it is a promising target for the development of gene therapy against breast cancers.

Abstract
ISSR markers were used to analyze the genetic diversity and genetic structure of eight natural populations of Cupressus chengiana in China. ISSR analysis using 10 primers was carried out on 92 different samples. At the species level, 136 polymorphic loci were detected. The percentage of polymorphic bands (PPB) was 99%. Genetic diversity (He) was 0.3120, effective number of alleles (Ae) was 1.5236, and Shannon's information index (I) was 0.4740. At the population level, PPB = 48%, Ae = 1.2774, He = 0.1631, and I = 0.2452. Genetic differentiation (Gst) detected by Nei's genetic diversity analysis suggested 48% occurred among populations. The partitioning of molecular variance by AMOVA analysis indicated significant genetic differentiation within populations (54%) and among populations (46%; P < 0.0003). The average number of individuals exchanged between populations per generation (Nm) was 0.5436. Samples from the same population clustered in the same population-specific cluster, and two groups of Sichuan and Gansu populations were distinguishable. A significantly positive correlation between genetic and geographic distance was detected (r = 0.6701). Human impacts were considered one of the main factors to cause the rarity of C. chengiana, and conservation strategies are suggested based on the genetic characters and field investigation, e.g., protection of wild populations, reestablishment of germplasm bank, and reintroduction of more genetic diversity.
