Abstract
Neuregulin 4 (NRG4) is an important adipocytokine, which plays crucial roles in maintaining energy balance, regulating glucose and lipid metabolism, and preventing non-alcoholic fatty liver disease in mammals. At present, the genomic organization, transcript and protein isoforms of human NRG4 gene have been fully explored. Previous studies in our laboratory have shown that the NRG4 gene is expressed in chicken adipose tissue, but the chicken NRG4 (cNRG4) genomic structure, transcript and protein isoforms are still unknown. To this end, in this study, the genomic and transcriptional structure of the cNRG4 gene were systematically investigated using rapid amplification of cDNA ends (RACE) and reverse transcription-polymerase chain reaction (RT-PCR). The results showed that the coding region (CDS) of the cNRG4 gene was small, but it had a very complex transcriptional structure characterized by multiple transcription start sites, alternative splicing, intron retention, cryptic exons, and alternative polyadenylation, thus leading to production of four 5?UTR isoforms (cNRG4 A, cNRG4 B, cNRG4 C, and cNRG4 D) and six 3?UTR isoforms (cNRG4 a, cNRG4 b, cNRG4 c, cNRG4 d, cNRG4 e, and cNRG4 f) of the cNRG4 gene. The cNRG4 gene spanned 21,969 bp of genomic DNA (Chr.10:3,490,314~3,512,282) and consisted of 11 exons and 10 introns. Compared with the cNRG4 gene mRNA sequence (NM_001030544.4), two novel exons and one cryptic exon of the cNRG4 gene were identified in this study. Bioinformatics analysis, RT-PCR, cloning and sequencing analysis showed that the cNRG4 gene could encode three protein isoforms (cNRG4-1, cNRG4-2 and cNRG4-3). This study lays a foundation for further research on the function and regulation of the cNRG4 gene.

Abstract
β decay of proton-rich nuclei plays an important role in exploring isospin mixing. The β decay of ^{26}P at the proton drip line is studied using double-sided silicon strip detectors operating in conjunction with high-purity germanium detectors. The T=2 isobaric analog state (IAS) at 13 055 keV and two new high-lying states at 13 380 and 11 912 keV in ^{26}Si are unambiguously identified through β-delayed two-proton emission (β2p). Angular correlations of two protons emitted from ^{26}Si excited states populated by ^{26}P β decay are measured, which suggests that the two protons are emitted mainly sequentially. We report the first observation of a strongly isospin-mixed doublet that deexcites mainly via two-proton decay. The isospin mixing matrix element between the ^{26}Si IAS and the nearby 13 380-keV state is determined to be 130(21) keV, and this result represents the strongest mixing, highest excitation energy, and largest level spacing of a doublet ever observed in β-decay experiments.

Abstract
Objective: To construct the geometric model of the pelvic floor by a two-dimensional equivalent mechanics method, and to explore the effect of the shape and position of pelvic floor organs and tissues on the biomechanical properties of the pelvic floor under different abdominal pressure. Methods: A 28-year-old healthy and symmetrical married infertile female volunteer was included. The pelvic floor tissue was scanned in the supine position using a 3.0T magnetic resonance scanner (Philips Company, Holland). Based on the method of magnetic resonance imaging (MRI) two-dimensional parameter measurement and computer aided design, the geometric model and finite element model of the female pelvic floor were established, and the biomechanical characteristics of the pelvic floor support system under different abdominal pressure were analyzed. Results: In this study, four different working conditions of the pelvic floor force were simulated under 60, 99, 168, and 208 cmH2O (1 cmH2O=0.098 kPa) abdominal pressure loads. The trend was as follows: under the abdominal pressure load, the retrograde flexion of the uterus occurred, the cervical, the middle and upper vaginal segment and the levator anus muscle had the characteristic change of mechanical axial direction pointing to the sacrum and coccyx, and the deformation of the levator anus muscle in the horizontal direction was greater than that in the vertical direction. With the increase of the abdominal pressure, the maximum stress values of the pelvic floor whole system of healthy subjects under four different working conditions were 0.194 3, 0.389 6, 0.557 1, and 0.627 5 MPa, respectively, and the maximum displacement values were 10, 14, 21 and 25 mm, respectively. The maximum stress values of the cervical and vaginal middle and upper segment were 0.111 7, 0.161 8, 0.250 6, and 0.304 1 MPa, respectively, and the maximum displacement values were 3, 6, 9, and 11 mm, respectively. The maximum stress of the perineal body was 0.063 4, 0.119 6, 0.235 2, and 0.288 0 MPa, and the maximum displacement was 1, 2, 4, and 5 mm. The maximum stress values of the levator anus muscle were 0.194 3, 0.389 6, 0.557 1, and 0.627 5 MPa, and the maximum displacement values were 2, 4, 7, and 8 mm, respectively. The maximum stress and maximum displacement of pelvic organs increased with the increase of the abdominal pressure under different working conditions. The stress axial relationship of normal female pelvic floor was that the middle and upper segment of uterus and vagina mainly acted on the sacrococcyx and the levator anus muscle, and the lower vaginal segment acts on the perineal body. Conclusions: The two-dimensional equivalent mechanical modeling and finite element analysis of the female pelvic floor system can accurately reflect the biomechanical characteristics of the female pelvic floor, and the resultant stress direction of the pelvic organs points to the sacrum and coccyx. The sacrum and coccyx, levator anus and perineal body play important stress supporting roles in the pelvic floor system.

Agarwood is the product of Aquilaria trees in response to injury and fungal infection. AP2/ERF transcription factors play important roles in plant stress responses and metabolite biosynthesis. In this study, 119 AsAP2/ERF genes were identified from the A. sinensis genome and divided into ERF, AP2, RAV and Soloist subfamilies. Their conserved motif, gene structure, chromosomal localization, and subcellular localization were characterized. A stress/defense-related ERF-associated amphiphilic repression (EAR) motif and an EDLL motif were identified. Moreover, 11 genes that were highly expressed in the agarwood layer in response to whole-tree agarwood induction technique (Agar-Wit) treatment were chosen, and their expression levels in response to MeJA, SA or salt treatment were further analyzed using qRT-PCR. Among the 11 genes, eight belonged to subgroup B-3. All 11 genes were significantly upregulated under salt treatment, while eight genes were significantly induced by both MeJA and SA. In addition, the gene clusters containing these upregulated genes on chromosomes were observed. The results obtained from this research not only provide useful information for understanding the functions of AP2/ERF genes in A. sinensis but also identify candidate genes and gene clusters to dissect their regulatory roles in agarwood formation for future research.

Abstract
The basic helix-loop-helix (bHLH) transcription factors are involved in several biological processes both in plant development and stress responses. Agarwood, a major active and economical product, is only induced and accumulated when the roots, stems, or branches are wounded in Aquilaria sinensis. Although genome-wide comprehensive analyses of the bHLH family have been identified in many plants, no systematic study of the genes in this family has been conducted in A. sinensis. In this study, 105 bHLH genes were identified in A. sinensis through genome-wide analysis and named according to their chromosomal locations. Based on a phylogenetic tree, AsbHLH family proteins were classified into 18 subfamilies. Most of them were distributed on eight chromosomes, with the exception of two genes. Based on the tissue-specific expression characteristics and expression patterns in response to methyl jasmonate (MeJA) treatment, seven AsbHLH genes were likely involved in wound-induced agarwood formation. The results provide comprehensive information on AsbHLHs that can be used to elucidate the molecular functions and physiological roles of these proteins in A. sinensis.

Abstract
Many people experience high burden by the outbreak of the coronavirus disease (COVID-19) and its consequences for health and everyday life. The present cross-national study investigated potential factors that can reduce the burden by COVID-19 in China and Germany. Cross-sectional and longitudinal (China: N = 474, baseline, BL: 2015, follow-up, FU: 2020; Germany: N = 359, BL: 2019, FU: 2020) data on physical activity (e.g., jogging) (BL/FU), positive mental health (PMH) (BL/FU), and burden by COVID-19 (FU) were collected via online surveys. In both countries, physical activity was positively associated with PMH, and both variables were negatively related to burden by COVID-19. Furthermore, PMH mediated the link between physical activity and burden. The mediation model was significant when physical activity and PMH were assessed at the BL, while burden was measured at the FU; and it was also significant when all variables were assessed at the FU. The present findings reveal that physical activity in combination with PMH can reduce the experience of burden by COVID-19. Conscious fostering of physical activity and PMH is supported as an effective strategy to reduce the negative impact of the pandemic outbreak on mental and physical health. Additional benefits such as increased adherence to governmental measures around COVID-19 are discussed.

Abstract
Objective: To evaluate the value of the age-adjusted Charlson comorbidity Index (ACCI) in predicting the prognosis and guiding the clinical treatment of laryngeal squamous cell carcinoma (LSCC) in patients over 60 years old. Methods: Retrospective analysis of 249 cases of LSCC in Shanxi Provincial Cancer Hospital and First Hospital of Shanxi Medical University from 2008 to 2015 was performed. There were 234 males and 15 females, aged from 60 to 88 years. The clinical characteristics, treatment information and follow-up data were collected. ACCI was used to score the comorbidities of the patients. Receiver operating characteristic (ROC) curve was drawn and the patients were divided into high ACCI group and low ACCI group according to the cut-off value of ACCI. Prognostic factors were analyzed. Kaplan-Meier method was used for survival analysis, rank sum test was used for comparison between groups, χ2 test was used for enumeration data. Results: Overall survival (OS) was 54.6%, progression-free survival (PFS) was 59.4%, and cancer-specific survival (CSS) was 58.6%. Both the median survival time and PFS time were 60 months. The best cutoff point of the ACCI group was 5. Cox multivariate analysis showed that ACCI was an independent risk factor for OS, PFS and CSS (OR=1.553, 1.499 and 1.534,respectively, all P<0.05). In the high ACCI group, OS (χ2=4.120 and 4.115,P<0.05) and CSS (χ2=4.510 and 5.009,P<0.05) of patients treated with surgery plus radiotherapy and patients with radiotherapy alone were better than those of patients with surgery alone (P<0.05). But in the low ACCI group, there was no significant difference in prognosis among the three treatment regimens (P>0.05). Conclusion: High ACCI offors important prognostic information for LSCC in patients over 60 years old, and can guide clinical treatment options.

Abstract
Objective: To investigate the association of hyperuricemia-induced renal damage with sirtuin 1 (SIRT1) and endothelial nitric oxide synthase (eNOS) in rats. Methods: Using the random number table method, 32 Sprague-Dawley rats were randomly divided into 4 groups: control group, model A group (the model was generated using oxonic acid potassium salt alone), model B group (hyperuricemia model was generated using oxonic acid potassium salt combined with uric acid) and resveratrol group, with 8 rats in each group. The experiment lasted 12 weeks. Serum uric acid and cystatin C levels were monitored regularly. In week 12, serum creatinine and urea nitrogen levels were measured, and the kidneys were extracted. The expression of SIRT1 and eNOS in renal tissues was measured and determined by immunohistochemistry, quantitative reverse-transcription polymerase chain reaction (RT-qPCR) and western blotting. Immunohistochemistry of alpha-smooth muscle actin combined with Masson staining was employed to evaluate the degree of renal fibrosis, and pathological changes were observed based on hematoxylin and eosin staining. Results: In week 12, the uric acid levels in both the model A and model B groups were higher than those in the control group [(316±43) μmol/L, (297±40) μmol/L vs (118±44) μmol/L, both P<0.05]. The levels of cystatin C in the model A, model B, and resveratrol groups were all higher than those in the control group [(156±20) ng/ml, (143±29) ng/ml, (128±26) ng/ml vs (62±18) ng/ml, all P<0.05]. Creatinine levels were higher in the model A and model B groups than those in the control group [(68.5±10.3) μmol/L, (64.5±13.9) μmol/L vs (43.2±10.6) μmol/L, both P<0.05]. The levels of uric acid, cystatin C and creatinine in the resveratrol group were lower than those in the model A group (all P<0.05). Immunohistochemistry, RT-qPCR, and Western blotting for renal SIRT1 and eNOS showed that the expression in the model A and model B groups was inhibited, while the expression in the resveratrol group was not significantly inhibited, compared with that in the control group. Microscopically, obvious abnormalities were not found in the renal tissue of the control group. Renal inflammatory cell aggregation and edema occurred, and interstitial fibrosis was obvious in both the model A and model B groups, while these lesions in the resveratrol group were significantly improved. Conclusions: Hyperuricemia may cause renal injury by inhibiting the expression of SIRT1 and eNOS.

Abstract
Aquilaria sinensis is a typical inducible medicinal plant, that can produce agarwood only after it is wounded by external stimuli. Alternative oxidase(AOX) is one of the terminal oxidases of the plant mitochondrial electron transport, which plays an important role in plants' response to environmental stress. In order to reveal the physiological function of AOX gene in the process of agarwood formation from A.sinensis induced by wounding, AOX gene was cloned based on the transcriptome database and then identified by the bioinformatics analysis, and their expression pattern in different tissues and under wounding stress were detected by qRT-PCR. The results as follows. Three AOX genes were cloned from A.sinensis for the first time. They were named AsAOX1a, AsAOX1d and AsAOX2, respectively. The tissue expression shown that AsAOX1a is mainly expressed in the stem and the seed, and the AsAOX1d and AsAOX2 genes are mainly expressed in the pulp and the stem. AsAOX1a and AsAOX1d genes are highly responsive to wounding stress, and their response time was different. In addition, the expression of AsAOX1a and AsAOX2 induced by wounding are reduced by H_2O_2 treatment, but promoted by AsA treatment. The cloning, bioinformatics analysis and expression characteristics of AOX genes from A.sinensis provided basic information for further study the function of AOX genes in the development of A.sinensis, especially in the process of agarwood formation of A. sinensis induced by wounding.

Abstract
The outgrowth and metastasis of cervical cancer (CC) contribute to its malignancy. Pituitary Tumor Transforming Gene 1 (PTTG1) is upregulated in many types of cancer, and enhances tumor cell growth and metastasis. However, the activation and regulation of PTTG1 in CC, especially by its pseudogene PTTG3P, have not been shown. Here, we detected significantly higher levels of PTTG1 and PTTG3P in the resected CC tissue, compared to the paired adjacent normal cervical tissue. Interestingly, the PTTG3P levels positively correlated with the PTTG1 levels. High PTTG3P levels were associated with poor patients’ survival. In vitro, PTTG1 were increased by PTTG3P overexpression, but was inhibited by PTTG3P depletion in CC cells. However, PTTG3P levels were not altered by modulation of PTTG1 in CC cells, suggesting that PTTG3P is upstream of PTTG1. Moreover, PTTG3P increased CC cell growth, likely through CCNB1-mediated increase in cell proliferation, rather than through decrease in cell apoptosis. Furthermore, PTTG3P increased CC cell invasiveness, likely through upregulation of SNAIL and downregulation of E-cadherin. Our work thus suggests that PTTG3P may promote growth and metastasis of CC through PTTG1.

Abstract
An inelastic excitation and cluster-decay experiment ^{2}H(^{16}C,^{4}He+^{12}Be or ^{6}He+^{10}Be)^{2}H was carried out to investigate the linear-chain clustering structure in neutron-rich ^{16}C. For the first time, decay paths from the ^{16}C resonances to various states of the final nuclei were determined, thanks to the well-resolved Q-value spectra obtained from the threefold coincident measurement. The close-threshold resonance at 16.5 MeV is assigned as the J^{π}=0^{+} band head of the predicted positive-parity linear-chain molecular band with (3/2_{π}^{-})^{2}(1/2_{σ}^{-})^{2} configuration, according to the associated angular correlation and decay analysis. Other members of this band were found at 17.3, 19.4, and 21.6 MeV based on their selective decay properties, being consistent with the theoretical predictions. Another intriguing high-lying state was observed at 27.2 MeV which decays almost exclusively to ^{6}He+^{10}Be(∼6 MeV) final channel, corresponding well to another predicted linear-chain structure with the pure σ-bond configuration.

Abstract
Agarwood is derived from wounds in Aquilaria trees and is widely used in traditional medicine, incense, and perfume. Sesquiterpenes are one of the main active components in agarwood and are known to be induced by wounding or injury; However, the molecular mechanisms by which wounding leads to sesquiterpene formation remain largely unknown. Agarwood sesquiterpene synthase 1 (ASS1) is one of key enzymes responsible for the biosynthesis of sesquiterpenes and is a crucial jasmonate (JA)-responsive wound-inducible synthase. However, it is not known why ASS1 is not expressed in healthy trees and how its expression is induced as a result of wounding. Here, we report that ASS1 is a wound-induced gene with a promoter in which a 242-bp region (-973 to -731bp) is identified as the core sequence for responding to wound signals. AsWRKY44 binds directly to this region and represses ASS1 promoter activity. Down-regulation or disruption of AsWRKY44 can relieve the inhibition and activate ASS1 expression. In addition, AsWRKY44 is degraded and the expression of ASS1 is significantly up-regulated in response to exogenous application of methyl jasmonate. Thus, AsWRKY44 is a crucial negative regulator of wound-induced ASS1 transcription, and is central to the mechanism of sesquiterpene biosynthesis in agarwood.

Abstract
Kidney‑type glutaminase (GLS1) plays a significant role in tumor metabolism. Our recent studies demonstrated that GLS1 was aberrantly expressed in hepatocellular carcinoma (HCC) and facilitated tumor progression. However, the roles of GLS1 in intrahepatic cholangiocarcinoma (ICC) remain largely unknown. Thus, the aim of this study was to evaluate the expression and clinical significance of GLS1 in ICC. For this purpose, combined data from the Oncomine database with those of immunohistochemistry were used to determine the expression levels of GLS1 in cancerous and non‑cancerous tissues. Second, a wound‑healing assay and Transwell assay were used to observe the effects of the knockdown and overexpression of GLS1 on the invasion and migration of ICC cells. We examined the associations between the expression of GLS1 and epithelial‑mesenchymal transition (EMT)‑related markers by western blot analysis. Finally, we examined the associations between GLS1 levels and clinicopathological factors or patient prognosis. The results revealed that GLS1 was overexpressed in different digestive system tumors, including ICC, and that GLS1 expression in ICC tissue was higher than that in peritumoral tissue. The overexpression of GLS1 in RBE cells induced metastasis and invasion. Moreover, the EMT‑related markers, E‑cadherin and Vimentin, were regulated by GLS1 in ICC cells. By contrast, the knockdown of GLS1 expression in QBC939 cells yielded opposite results. Clinically, a high expression of GLS1 in ICC samples negatively correlated with E‑cadherin expression and positively correlated with Vimentin expression. GLS1 protein expression was associated with tumor differentiation (P=0.001) and lymphatic metastasis (P=0.029). Importantly, patients with a high GLS1 expression had a poorer overall survival (OS) and a shorter time to recurrence than patients with a low GLS1 expression. Multivariate analysis indicated that GLS1 expression was an independent prognostic indicator. On the whole, the findings of this study demonstrated that GLS1 is an independent prognostic biomarker of ICC. GLS1 facilitates ICC progression and may thus prove to be a therapeutic target in ICC.

Abstract
Objective:The study aimed to investigate the efficacy of sublingual immunotherapy(SLIT) in treatment of adult allergic rhinitis, and to explore the predictive role of baseline serum cytokine levels in its therapeutic effect.Method:Sixty patients with moderatesevere perennial AR sensitized with house dust mites were treated for 2 years. The SLIT group(n=30) were treated with standardized dust mite vaccine SLIT and conventional drugs, and the control group(n=30) were treated with placebo and conventional drugs. The combined symptom and medication score(CSMS) were compared between the two groups to evaluate the efficacy at baseline and 2 year endpoint. According to therapeutic effect, the SLIT group and the control group were divided into subgroups respectively, and the baseline IFN-γ and IL4, IL10, IL17 levels were compared between the effective group and the ineffective group in each group. The ROC curve was drawn to find the best predictive index and the best cut-off value was calculated. Result:①There was no significant difference between the SLIT group and the control group at baseline CSMS(P>0.05). There was significant difference between the two groups at 2year endpoint CSMS(P<0.05). ②In the SLIT group, there was no significant difference between the effective group and the ineffective group with the IFN-γ and IL17(P>0.05). The IL4 level in the effective group was significantly higher than the ineffective group while the IL10 level was significantly lower(P<0.05). In the control group, there were no significant differences in the levels of IFN-γ, IL4, IL10 and IL17 between the two subgroups(P>0.05). ③Baseline IL4/IL10 has higher predictive value than IL4 and IL10 alone. The best cut-off value is 2.04, and the sensitivity and specificity of predictive value were 72.7% and 73.7% respectively. Conclusion: SLIT combined with conventional drug therapy is more effective than conventional drug therapy alone. IL4/IL10 has a better predictive role in SLIT effect than IL4 or IL10 alone. The higher the ratio, the better therapeutic effect is.

Abstract
Perennial tree Dalbergia odorifera T. Chen could form the precious heartwood used to produce chinese traditional medicine, rosewood furniture and fragrances. However the formation of heartwood is time-consuming and low efficient, leading to the severe destruction of its wild resources. Thus, it is urgent to study the molecular mechanism of heartwood formation in D. odorifera. But till now, there is no report about the reference gene selection in this species. In this study, the expression stability of nine candidate reference genes were evaluated across different tissues and stems treated by wound and chemical stimulators. Four algorithms were applied to obtain the robust genes. The results support HIS2, GAPDH, and CYP to be the most stable reference genes in samples under different wound treatments while DNAj was the least stable. In different tissues, HIS2, UBQ, and RPL were the most stable reference genes while DNAj was the least stable. The selected reference genes were validated through the normalization of the qRT-PCR data of six heartwood related genes in terpene biosynthesis pathway and ethylene signal pathway. The results showed that their expression levels were accurate when they were normalized by the most stable reference gene HIS2, or by the combination of the two or three most stable reference genes. These results demonstrated that these selected reference genes are reliable.

Abstract
Objective:To study the differences in cognitive function between patients with laryngeal carcinoma and healthy volunteers. Method:Patients with laryngeal carcinoma who have been first diagnosed with laryngeal carcinoma, but not received treatment at the Department of Otolaryngology in two hospitals in Shanxi Province and healthy volunteers of the same age, gender-matched and similar education were studied for the purpose to evaluate the cognitive status by using the Wechsler memory scale.Result:No significant difference of age, gender and educational level was found between both groups(P>0.05).The score of Memory Quotient was significantly lower in the laryngeal carcinoma group than that in healthy control group (P<0.05). There were significant differences in the results of Wechsler memory scale except for Experience, Orientation and Association test (P<0.05).Conclusion:The memory, attention and computing power of patients in the laryngeal carcinoma group were not as good as those of patients in the healthy control group. Patients with laryngeal carcinoma have cognitive impairment or lower ability , so we need to pay more attention to the patients during their rehabilitation. The early detection of cancer-related cognitive impairments can help patients improve their cognitive function early, reduce the burden on their families and society, and promote better return of patients to society.

Abstract
Polyketides are a large class of natural products with notable structural diversity and different biological activities. They have essential pharmacological value for human health. In plants, the enzymes responsible for the formation of phenolic metabolites backbone structures are collectively known as type Ⅲ polyketide synthases (PKSs), which are the key enzymes for the polyketides biosynthesis. The PKSs catalyze a series of condensation reactions of two-carbon acetate units with an acyl starter. A brief overview of this group of enzymes, including their reaction mechanisms, function modification, expression regulation, molecular evolution, and recent interesting findings are presented here.

Abstract
Sesquiterpenes are one of the most important defensive secondary metabolite components of agarwood. Agarwood, which is a product of the Aquilaria sinensis response to external damage, is a fragrant and resinous wood that is widely used in traditional medicines, incense and perfume. We previously reported that jasmonic acid (JA) plays an important role in promoting agarwood sesquiterpene biosynthesis and induces expression of the sesquiterpene synthase ASS1, which is a key enzyme that is responsible for the biosynthesis of agarwood sesquiterpenes in A. sinensis. However, little is known about this molecular regulation mechanism. Here, we characterized a basic helix-loop-helix transcription factor, AsMYC2, from A. sinensis as an activator of ASS1 expression. AsMYC2 is an immediate-early jasmonate-responsive gene and is co-induced with ASS1. Using a combination of yeast one-hybrid assays and chromatin immunoprecipitation analyses, we showed that AsMYC2 bound the promoter of ASS1 containing a G-box motif. AsMYC2 activated expression of ASS1 in tobacco epidermis cells and up-regulated expression of sesquiterpene synthase genes (TPS21 and TPS11) in Arabidopsis, which was also promoted by methyl jasmonate. Our results suggest that AsMYC2 participates in the regulation of agarwood sesquiterpene biosynthesis in A. sinensis by controlling the expression of ASS1 through the JA signaling pathway.

Abstract
Sesquiterpenes are one of the most important defensive secondary metabolite components of agarwood. Agarwood, which is a product of the Aquilaria sinensis response to external damage, is a fragrant and resinous wood that is widely used in traditional medicines, incense and perfume. We previously reported that jasmonic acid (JA) plays an important role in promoting agarwood sesquiterpene biosynthesis and induces expression of the sesquiterpene synthase ASS1, which is a key enzyme that is responsible for the biosynthesis of agarwood sesquiterpenes in A. sinensis. However, little is known about this molecular regulation mechanism. Here, we characterized a basic helix-loop-helix transcription factor, AsMYC2, from A. sinensis as an activator of ASS1 expression. AsMYC2 is an immediate-early jasmonate-responsive gene and is co-induced with ASS1. Using a combination of yeast one-hybrid assays and chromatin immunoprecipitation analyses, we showed that AsMYC2 bound the promoter of ASS1 containing a G-box motif. AsMYC2 activated expression of ASS1 in tobacco epidermis cells and up-regulated expression of sesquiterpene synthase genes (TPS21 and TPS11) in Arabidopsis, which was also promoted by methyl jasmonate. Our results suggest that AsMYC2 participates in the regulation of agarwood sesquiterpene biosynthesis in A. sinensis by controlling the expression of ASS1 through the JA signaling pathway.

Abstract
Fruit ripening is a complex developmental process, the details of which remain largely unknown in fleshy fruits. In this paper, the fruit flesh of two peach varieties, "Zhongyou9" (a nectarine; Prunus persica L. Batsch) and its mutant "Hongyu", was analyzed by RNA-seq technology during two stages of ripening at 20-day intervals. One hundred and eighty significant upregulated and two hundred and thirty-five downregulated genes were identified in the experiment. Many of these genes were related to plant hormones, chlorophyll breakdown, accumulation of aroma and flavor volatiles, and stress. To the best of our knowledge, this is the first transcriptome analysis of peach ripening, and our data will be useful for further studies of the molecular basis of fruit ripening.

Abstract
OBJECTIVE To investigate the expression of Jagged1 in human epithelial ovarian carcinoma tissues and the effect of Jagged1 on growth of xenograft in nude mice. METHODS (1) Forty-eight cases of ovarian cancer and 30 cases of patients with benign epithelial ovarian tumor in the Henan Province Xinxiang Central Hospital during Feb. 2011 to Mar. 2014 were enrolled in this study. The mRNA expression of Jagged1, Notch1 and the downstream target genes Hes1, Hey1 were analyzed by using realtime PCR method. (2) The ovarian cancer xenograft models in nude mice were constructed by injecting SKOV3 cells in axillary subcutaneouswere. The nude mice were randomly divided into Jagged1 interference group, blank plasmid group and control group. Each group had 10 mice. They were transfected with pcDNA3.1(+)-siRNA-Jagged1, blank plasmid pDC3.1 and phosphate buffer, respectively. The tumor volumes and tumor masses were measured 14 days after transfection and the inhibition rate was calculated. The relative mRNA expression of Jagged1, Notch1, Hes1 and Hey1 in xenograft tissues after transfection in each group was detected by using realtime PCR technique and the relative protein expression of Jagged1, Notch1, Hes1 and Hey1 in xenograft tissues was detected by utilizing western blot method. RESULTS (1) The relative mRNA expression of Jagged1, Notch1, Hes1 and Hey1 in ovarian cancer tissues were higher than benign ovarian tumor tissues, the differences were statistically significant (P<0.01). (2) The tumor volume was (491± 68) mm(3) and tumor mass was (2.6±0.4) g in Jagged1 interference group, which were significantly lower than that in the blank plasmid group [(842±88) mm(3) and (4.4±0.8) g, respectively] and that in the control group [(851±90) mm(3) and (4.5±0.9) g, respectively; P<0.05], the tumor inhibition rate was 42.2% in Jagged1 interference group, which was significantly higher than that in the blank plasmid group and that in the control group (2.2% and 0, respectively), the differences were statistically significant (P<0.05). The relative mRNA and protein expression of Jagged1, Hes1 and Hey1 in xenograft tissues of nude micein Jagged1 interference group were lower than that in the other two groups, the differences were statistically significant (P<0.05). There were no differences of relative mRNA and protein expression of Notch1 in xenograft tissues of nude mice among the three groups (P>0.05). CONCLUSIONS Jagged1 is highly expressed in epithelial ovarian carcinoma. Jagged1 gene interference in xenograft tumor can inhibit ovarian cancer cell growth and improve tumor suppressor rate, which probably play roles by inhibiting Notch1 signaling pathway.

Abstract
In the present study, we investigated the combined effect of Colla Comus Cervi (CCC) and BMP7-overexpressing bone marrow-derived mesenchymal stem cells (BMSCs) on osteogenic induction and the treatment of avascular necrosis of the femoral head (ANFH). BMSCs were isolated from rats. BMP7-overexpressing BMSCs were generated by lentiviral-mediated gene transduction. Cell proliferation, alkaline phosphatase (ALP) activity, osteogenesis related gene expression, osteocalcin levels, and calcified nodules were quantified and compared between four groups: untreated controls, BMSCs cultured with CCC complex medium, BMP7-overexpressing BMSCs, and BMP7-overexpressing BMSCs cultured with CCC complex medium (CCC+BMP7). CCC+BMP7 BMSCs showed higher proliferation rate. ALP activity and osteaocalcin content were significantly increased in CCC+BMP7 BMSCs. The osteogenesis related genes, COLI, and integrin-α2, -α5, and -β1, were expressed significantly higher in CCC+BMP7 BMSCs. The number of calcified nodules in the CCC+BMP7 group was significantly higher than that in other groups. For in vivo assays, ANFH was induced in rats, and BMSCs were injected into the femoral head of the lower left extremity. In rats with induced ANFH, general observation scores of the CCC+BMP7 injected group were significantly higher than the model group. X-ray and microscopic observations revealed that ANFH was significantly improved and femoral head cells gradually recovered in rats treated with CCC+BMP7 BMSCs. Our results suggest that CCC+BMP7 significantly promote the proliferation and osteogenic differentiation of BMSCs in vitm. CCC+BMP7 BMSCs promote the ability of repairing ANFH in rats, providing a new therapeutic paradigm for the treatment of ANFH.

Abstract
Simple sequence repeats (SSRs), one of the most powerful molecular markers, can be used for DNA fingerprinting, variety identification, genetic mapping, and marker-assisted selection. Using the pear's (Pyrus pyrifolia Nakai) 75,764 unigenes (55,676,271 bp) obtained by deep transcriptome sequencing, a total of 10,622 novel SSRs were identified in 9154 unigenes, accounting for 14.02% of all unigenes. The average length and distribution of these SSRs was about 16 bp and 5.24 kb, respectively. Dinucleotide repeat motifs were the main type, with a frequency of 55.87%, followed by trinucleotides (24.45%). There were 159 kinds of repeat motifs existing in the pear transcriptome. AG/CT was the most frequent motif, accounting for 49.64%. All 9154 SSR-containing unigenes were functionally annotated using Nr (NCBI non-redundant protein database), Nt (NCBI non-redundant nucleotide database), and the Swiss-Prot database, and were classified further by Gene Ontology and Clusters of Orthologous Groups. In addition, a total of 4300 primer pairs were designed from all SSR loci obtained. Of these, 40 primers were randomly selected for PCR amplification and polyacrylamide gel (PAGE) analysis. Among the 40 primer pairs, 31 were successfully separated via PAGE. These findings also confirm that mining SSRs using next-generating sequencing technologies is a fast, effective, and reliable approach.

Abstract
OBJECTIVE To analyze the reasons of early failure of the PHILOS in proximal humerus fractures. METHODS From Nov. 2010 to Nov. 2014, there were 117 patients with humerus fractures treated with PHILOS locking plate in Department of Orthopaedics, Xuanwu Hospital. All of the patients were treated with the plate by open reduction internal fixation, and we analyzed these cases retrospectively. After the operation, we removed the drainage tube within 48 h, and the patients were allowed to do the passive motion 3 days after the surgery if the X-Ray showed the plate and screws were reliable. Eight cases failed within 4 weeks after the operation. We analyzed the reasons of the failure. RESULTS The rate of the failed cases was 6.83%(8/117). The average age was 72.4(66-82) years. In the 8 failed cases, 3 were on the right side, and the other 5 on the left side. As for the reason of the fractures, 2 cases were because of car accidents, and the other 6 because of daily life injury. According to the Neer classification, 3 cases were 2-part fractures, and the other 5 3-part fractures. Three cases were total failure, and the other 5 partial failure. All the 8 failed cases failed within 4 weeks after the operation, of which 1 was on the sixth day after surgery, the other 7 2 to 4 weeks after the surgery.The 3 totally failed cases were treated by removing the screws and plates, the other 5 by conservative methods. All of the cases were malunion at the end. CONCLUSION The early failure of the PHILOS locking plate in proximal humerus fractures is related to the bad reduction during the operation, the loss of medial cortex support, the limitation of screw length, the osteoporosis and the improper rehabilitation after operation.It is very important to do good preoperative plan for a surgeon. During the operation, we should try our best in the fracture reduction, use the appropriate plate and screws, and then pay attention to the rehabilitation after the operation. After all of this, the rate of failure may be decreased.

Abstract
We previously reported that dental stem cell-mediated bioengineered tooth root (bio-root) regeneration could restore tooth loss in a miniature pig model. As a potential new method for tooth restoration, it is essential to compare this method with the widely used commercial dental implant-based method of tooth restoration. Tooth loss models were created by extracting mandibular incisors from miniature pigs. Allogeneic periodontal ligament stem cells (PDLSCs) and dental pulp stem cells (DPSCs) were isolated and cultured. A PDLSC sheet was prepared by adding 20.0 µg/mL vitamin C to the culture medium; in addition, a hydroxyapatite tricalcium phosphate (HA/TCP)/DPSC graft was fabricated and cultured in a 3-dimensional culture system. A total of 46 bio-root implantations and 9 dental implants were inserted, and crown restorations were performed 6 mo after implantation. Histological, radiological, biomechanical, and elemental analyses were used to evaluate and compare tissue-engineered bio-roots and dental implants to the natural tooth roots. After 6 mo, both computed tomography scans and histological examinations showed that root-like structures and dentin-like tissues had formed. Three months after crown restoration, clinical assessments revealed that tooth function was equivalent in the regenerated bio-root and the dental implant. Biomechanical testing showed that the bio-roots were similar to natural tooth roots in compressive strength, modulus of elasticity, and torsional force; however, these properties were significantly higher in the dental implants. Elemental analysis revealed a higher similarity in elemental composition between bio-roots and natural tooth roots than between bio-roots and dental implants. However, the dental implant success rate was 100% (9 of 9) and the bio-root success rate was only 22% (10 of 46). Taken together, we showed that an allogeneic HA/TCP/DPSC/PDLSC sheet could successfully build a bio-root with structure and function similar to the natural tooth root; however, tissue engineering procedures must be optimized further to improve the success rate.

Abstract
Agarwood, a highly valuable resinous and fragrant heartwood of Aquilaria plants, is widely used in traditional medicines, incense and perfume. Only when Aquilaria trees are wounded by external stimuli do they form agarwood sesquiterpene defensive compounds. Therefore, understanding the signaling pathway of wound-induced agarwood formation is important. Jasmonic acid (JA) is a well-characterized molecule that mediates a plant's defense response and secondary metabolism. However, little is known about the function of endogenous JA in agarwood sesquiterpene biosynthesis. Here, we report that heat shock can up-regulate the expression of genes in JA signaling pathway, induce JA production and the accumulation of agarwood sesquiterpene in A. sinensis cell suspension cultures. A specific inhibitor of JA, nordihydroguaiaretic acid (NDGA), could block the JA signaling pathway and reduce the accumulation of sesquiterpene compounds. Additionally, compared to SA and H2O2, exogenously supplied methyl jasmonate has the strongest stimulation effect on the production of sesquiterpene compounds. These results clearly demonstrate the central induction role of JA in heat-shock-induced sesquiterpene production in A. sinensis.

CONCLUSION The early failure of the PHILOS locking plate in proximal humerus fractures is related to the bad reduction during the operation, the loss of medial cortex support, the limitation of screw length, the osteoporosis and the improper rehabilitation after operation.It is very important to do good preoperative plan for a surgeon. During the operation, we should try our best in the fracture reduction, use the appropriate plate and screws, and then pay attention to the rehabilitation after the operation. After all of this, the rate of failure may be decreased.

Abstract
This study was to discuss the curative effect of paclitaxel and cisplatin combined chemotherapy on cervical cancer and its relation with tissue micro vascular and lymphatic vessels density. The combined chemotherapy of paclitaxel 135 mg/m² and cisplatin 25mg/m² were taken to observe the clinical curative effect. The postoperative paraffin tissue had been collected, had performed the LYVE-1 (lymphatic endothelium specific hyaluronan receptor-1) and CD31 immunohistochemical staining. The complete remission rate of high micro lymphatic vessels density group (was or more 6.0) and high micro vascular density group were obviously higher than in low micro lymphatic vessels density group and low micro vascular density group, the difference was statistically significance (P<0.05). This study further analyzed the relation of MVD and LVD with clinical pathological parameters. The difference was statistically significant (P<0.01). The curative effect of paclitaxel and cisplatin combined therapy was promising, positive and was closely related with cervical cancer tissue LVD and MVD. The LVD and MVD could be one of the predictors of early cervical CIN and early cervical cancer development.

Abstract
Single-crystals of titanium oxide (TiO2) were wrapped in a graphene (G) film by chemical deposition. The morphology, composition and structure of the resulting composite were subsequently characterized by SEM, TEM, XRD and FT-IR analysis. The electrochemical properties of the composites were studied by cyclic voltammetry, which showed that the introduction of graphene enhances the electrode conductivity, thereby improving the supercapacitive behavior of TiO2. Galvanostatic charge-discharge tests demonstrated that a supercapacitor device fabricated from TiO2 crystals wrapped in graphene (G-TiO2) exhibits a good cycle life, with 94% stability even after 1000 cycles.

Abstract
Flower color is an important trait of the ornamental peach (Prunus persica L.). However, the mechanism responsible for the different colors that appear in the same genotype remains unclear. In this study, red samples showed higher anthocyanins content (0.122 ± 0.009 mg/g), which was significantly different from that in white samples (0.066 ± 0.010 mg/g). Similarly to carotenoids content, red extract (0.058 ± 0.004 mg/L) was significantly higher in white extract (0.015 ± 0.004 mg/L). We estimated gene expression using Illumina sequencing technology in libraries from white and red flower buds. A total of 3,599,960 and 3,464,141 tags were sequenced from the 2 libraries, respectively. Moreover, we identified 106 significantly differentially expressed genes between the 2 libraries. Among these, 78 and 28 represented transcripts with a higher or lower abundance of more than 2-fold than in the white flower library, respectively. GO annotation indicated that highly ranked genes were involved in the pigment biosynthetic process. Expression patterns of 11 genes were verified using quantitative reverse transcription-polymerase chain reaction assays. The results suggest that hydroxycinnamoyl-coenzyme A shikimate/quinate hydroxycinnamoyltransferase, 2-oxoglutarate-dependent dioxygenase, isoflavone reductase, riboflavin kinase, zeta-carotene desaturase, and ATP binding cassette transporter may be associated with the flower color formation. Our results may be useful for scientists focusing on Prunus persica floral development and biotechnology.

Abstract
BACKGROUND Enrolling patients in studies of pancreatic ductal adenocarcinoma (pdac) is challenging because of the high fatality of the disease. We hypothesized that a prospective clinic-based study with rapid ascertainment would result in high participation rates. Using that strategy, we established the Quebec Pancreas Cancer Study (qpcs) to investigate the genetics and causes of pdac and other periampullary tumours (pats) that are also rare and underrepresented in research studies. METHODS Patients diagnosed with pdac or pat were introduced to the study at their initial clinical encounter, with a strategy to enrol participants within 2 weeks of diagnosis. Patient self-referrals and referrals of unaffected individuals with an increased risk of pdac were also accepted. Family histories, epidemiologic and clinical data, and biospecimens were collected. Additional relatives were enrolled in families at increased genetic risk. RESULTS The first 346 completed referrals led to 306 probands being enrolled, including 190 probands affected with pdac, who represent the population focus of the qpcs. Participation rates were 88.4% for all referrals and 89.2% for pdac referrals. Family history, epidemiologic and clinical data, and biospecimens were ascertained from 91.9%, 54.6%, and 97.5% respectively of patients with pdac. Although demographics and trends in risk factors in our patients were consistent with published statistics for patients with pdac, the qpcs is enriched for families with French-Canadian ancestry (37.4%), a population with recurrent germ-line mutations in hereditary diseases. CONCLUSIONS Using rapid ascertainment, a pdac and pat research registry with high participation rates can be established. The qpcs is a valuable research resource and its enrichment with patients of French-Canadian ancestry provides a unique opportunity for studies of heredity in these diseases.

Abstract
Hepatocellular carcinoma (HCC) is one of the few cancers whose incidence has been continually increasing over recent years. Resection of HCC offers the only hope for cure. However, recurrences are common in patients who have undergone resection. In our opinion, the effectiveness with which transarterial chemoembolization (TACE) as a neoadjuvant therapy for resectable HCC prevents recurrence and prolongs survival has not been conclusively demonstrated. All published meta-analyses have consistently failed to demonstrate that preoperative TACE improves the prognosis of resectable HCC. We believe that these published articles have several limitations and have our own views about the results of meta-analyses. It is very important that the scientific community shed more light on the pathogenesis of HCC and relate this to choice of therapy. This review mainly concerns our understanding of preoperative TACE for resectable HCC and briefly addresses desirable directions for future studies.

Abstract
Haemaphysalis longicornis (Ixodida: Ixodidae) is an important vector of transovarially transmitted parasites of the genus Babesia (Piroplasmida: Babesiidae). In the present study, we investigated the morphological characteristics and developmental changes of the ovary of H. longicornis. We show that the ovary of H. longicornis has a single tubular structure and is surrounded by a tunica propria. There is a longitudinal groove along one side of the ovary. During feeding and after engorgement, great changes can be observed in the ovary of H. longicornis and two rapid growth phases can be detected. The number of major protein bands of the ovary is significantly increased from day 3 of feeding and reaches a maximum on the day of engorgement. Therefore, the great diversity of proteins in the ovaries of H. longicornis can facilitate the identification of new targets for vaccine development.

Abstract
Agarwood, a kind of highly valued non-timber product across Asia, is formed only when its resource trees -- the endangered genus Aquilaria are wounded or infected by some microbes. To promote the efficiency of agarwood production and protect the wild resource of Aquilaria species, we urgently need to reveal the regulation mechanism of agarwood formation. MicroRNAs (miRNAs) are a group of gene expression regulators with overwhelming effects on a large spectrum of biological processes. However, their roles in agarwood formation remain unknown. This work aimed at identifying possible miRNAs involved in the wound induced agarwood formation. In this study, the high-throughput sequencing was adopted to identify miRNAs and monitor their expression under wound treatment in the stems of A. sinensis. The miR171, miR390, miR394, miR2111, and miR3954 families remained at the reduced level two days after the treatment. 131 homologous miRNAs in the 0.5 h library showed over three-fold variation of read number compared with the control library, of which 12 exhibiting strong expression alterations were further confirmed by real-time quantitative PCR. Target prediction and annotation of the miRNAs demonstrated that the binding, metabolic process, catalytic activity, and cellular process are the most common functions of the predicted targets of these newly identified miRNAs in A.sinensis. The cleaveage sites of three newly predicted targets were verified by 5'RACE.

Abstract
OBJECTIVE To investigate the type and frequency of mutations in exon 7 of phenylalanine hydroxylase (PAH) gene among children with phenylketonuria (PKU) in Ningxia, China and to provide a basis for the genetic diagnosis and prenatal diagnosis of PKU in this region. METHODS Direct sequencing of PCR product was performed to analyze the sequences of exon 7 and its flanking introns of 146 PAH alleles in 73 children with typical PKU (39 cases of Hui nationality and 34 cases of Han nationality) in Ningxia. RESULTS Six mutations were detected, including R243Q (14.4%), R241C (6.8%), IVS7+2T→A (2.7%), L255S (0.7%), G247V (0.7%), and G247R (0.7%). The overall frequency of mutations (missense mutation and splice site mutation) in exon 7 was 26.0% (38/146). The detection rate of R241C mutation was significantly higher in children of Hui nationality than in children of Han nationality(10% vs 3%; P<0.05). CONCLUSIONS In Ningxia, R243Q mutation in exon 7 of PAH gene is most common in children with PKU, followed by R241C. The frequency of R241C mutation in exon 7 of PAH gene varies between children with PKU of Hui and Han nationality.

Abstract
OBJECTIVE This study aimed to clone the acetyl-CoA C-acetyl transferase (AACT) gene from Aquilaria sinensis and analyze the bioinformatics and expression of the gene. METHOD One unique sequence containing partly AACT gene sequence was discovered in our previous transcriptome dataset of A. sinensis. AACT gene was cloned by RT-PCR and RACE strategy with the template of RNA extracted from A. sinensis stem. The bioinformatic analysis of this gene and its corresponding protein was performed. The AsAACT expression in calli was analyzed with GADPH gene as an internal control gene in wounded condition by qRT-PCR technique. RESULT One unique sequence of AACT, named as AsAACT, was cloned from A. sinensis. The full length of AsAACT cDNA was containing a 1 236 bp ORF that encoded 411 amino acids. The result of qRT-PCR displayed that the highest expression level was at 4 h. which indicated that it was possibly involved in early-stage response to wound. CONCLUSION Cloning and analyzing AsAACT gene from A. sinensis provided basic information for study the function and expression regulation of AsAACT in terpenoid biosynthesis.

Abstract
To investigate the mechanism of agarwood formation in Aquilaria sinensis induced by Lasiodiplodia theobromae, the fermentation liquor of L. theobromae was analyzed qualitatively and quantitatively by gas chromatography-mass spectrometry (GC-MS). JAs were detected in the fermentation liquor. The effect of the fermentation liquor on the abundance of sesquiterpenes in the callus of A. sinensis was analyzed by solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS). And the fermentation liquor stimulated alpha-guaiene, alpha-humulene and delta-guaiene biosynthesis in calli. It was inferred that L. theobromae produced JAs, which resulted in a significant increase of sesquiterpenes in A. sinensis.

Abstract
SFB, a candidate gene for the pollen S gene, has been identified in several species of Prunus (Rosaceae). We isolated 5 new SFB alleles from 6 Japanese apricot (Prunus mume) lines using a specific Prunus SFB primer pair (SFB-C1F and Pm-Vb), which was designed from conserved regions of Prunus SFB. The nucleotide sequences of these SFB genes were submitted to the GenBank database. The 5 new SFB alleles share typical structural features with SFB alleles from other Prunus species and were found to be polymorphic, with 67.08 to 96.91% amino acid identity. These new SFB alleles were specifically expressed in the pollen. We conclude that the PmSFB alleles that we identified are the pollen S determinants of Japanese apricot; they have potential as a tool for studies of the mechanisms of pollen self-incompatibility.

Abstract
UNLABELLED Agarwood is a high-valued woody material for medicine, perfume, and incense production in Asia, Middle East, and Europe. The wild resources of agarwood-producing tree species, e.g., Aquilaria sinensis have been greatly threatened. The formation of agarwood is considered to be associated with the plant stress and defensive responses, thus it would be urgent and significant to investigate the molecular mechanism of these species responding to a variety of stresses. This is the first report regarding the reference gene selection of Aquilaria species for studying the molecular mechanism of stress-related agarwood production. Candidate reference genes were selected according to previous reports and the sequences were obtained from the 454 EST library of A. sinensis. To obtain the robust genes, we applied three independent programs depending on distinct assumptions and combined these results by a rank aggregation algorithm. The result supports tubulin, ribosomal protein, and glyceraldehyde-3-phosphate dehydrogenase to be the most stable reference genes for quantification of target gene expression in the overall samples examined. Validation of these genes through normalizing the expression of a terpene synthase demonstrated that these three genes are reliable. The selective usage of three algorithms based on their characteristics was underlined. However, more robust genes could be identified if the results of all algorithms were combined by a proper method such as the rank aggregation algorithm. KEY MESSAGE Reference genes which are critical in gene expression studies are recommended for future molecular studies of stress response and agarwood production in the endangered Aquilaria and other tree species.

Abstract
Bupleurum chinense DC. (family Umbelliferae) is an important medicinal herb in traditional Chinese medicine and is cultivated as an economically important plant in China (2). From 2006 to 2009, severe foliar disease was observed on B. chinense in Haidian, Changping, and Shunyi districts, Beijing, China. Approximately 75 to 85% of fields were affected with disease incidence ranging from 65 to 90%. Distribution of the disease in affected B. chinense fields was generally associated with high soil moisture, often corresponding to poor drainage. Initial symptoms first appeared on older leaves as irregularly shaped, minute, dark brown-to-black spots, with yellow borders on the edge of the affected leaflet blade. As the disease progressed, the lesions expanded, causing the leaflets to turn brown, shrivel, and die. Isolations performed on potato dextrose agar (PDA) initially resulted in white colonies. After 7 days of incubation at 25°C, the colonies turned gray or brown. Conidia varied in size from 10 × 6 to 40 × 12 μm, appeared brown to dark brown or olive-brown, were short beaked and borne in long chains, oval and bean-shaped with one to six transverse septa and zero to three longitudinal septa. Sequences of the rDNA from the internal transcribed spacer regions 1 and 2 and the 5.8S gene were amplified using primers ITS1 and ITS4, were obtained from three isolates, and comparisons with GenBank showed 100% similarity with A. alternata (Genbank Accession No. AB470912.1). For pathogenicity tests, three isolates were grown on PDA for 14 days. Inoculations were performed on detached, surface-sterilized, and healthy B. chinense leaflets following the method of Belisario (1). A 5-μl drop of conidial suspension containing 1 × 105 CFU/ml was placed on each leaflet and 12 leaves per isolate were used. Leaves were incubated in a growth chamber (80 to 90% relative humidity; 50 to 60 klx/m2 light intensity with a 12-h photoperiod). After 5 days, leaf spots similar to the original symptoms developed on all inoculated leaves and A. alternata was consistently reisolated from symptomatic leaf tissues on PDA. Control leaflets inoculated with sterile water remained asymptomatic. The experiment was performed three times. To our knowledge, this is the first report of A. alternata on B. chinense from China.

Abstract
pH may act as a crucial signal in both animal and plant cells. It is very difficult to monitor pH signals and this has largely hindered progress in the investigation of pH signaling, particularly systematic pH signaling. Here, we report the development of a confocal technique to monitor leaf apoplastic pH in intact plants, which is particularly suitable for the studies on root to shoot signaling. A variety of different pH indicators and plant species were tested. It was found that different pH indicators, for example, 2',7'-Bis-(2-carboxyethyl)-5-(and-6)-carboxyfluoresce (BCECF), SNARF-4F 5-(and-6)-carboxylic acid (SNARF) and DM-NERF (NERF), were of different properties, and to successfully monitor pH at a sub-cellular level, the comparability between the pH indicator and plant species must be involved according to their suitable pH range and loading characteristics. The loading characteristics of different pH indicators differ with different plant species, cell types and their developing stages. No matter what methods were adopted, BCECF and SNARF could not be loaded specifically in the leaf apoplast in sunflower, tomato, and Comelina communis L. In contrast, regardless of the methods adopted, NERF could be loaded efficiently and specifically in the leaf apoplast in C. communis, but not in other plants. In C. communis, the determination coefficient for in vitro and in situ calibration of NERF was very high, which was respectively 0.9951 and 0.9916, and therefore, the adoption of NERF together with C. communis could construct an ideal experimental system that is suitable for the investigation of pH systematic signaling. Ratio image analysis demonstrated that the leaf apoplastic pH was about 5.5 in non-stressed conditions, and water deficit could trigger an increase in pH by about half a pH unit, which is the first evidence to directly indicate that pH is able to act as a systematic signal under water deficit conditions.

Abstract
We have used site-directed mutagenesis, flow dialysis, and Fourier transform infrared (FTIR) spectroscopy to study Ca(2+)-binding to the regulatory component of calcineurin. Single Glu-Gln(E --> Q) mutations were used to inactivate each of the four Ca(2+)-binding sites of CnB in turn, generating mutants Q1, Q2, Q3, and Q4, with the number indicating which Ca(2+) site is inactivated. The binding data derived from flow dialysis reveal two pairs of sites in the wild-type protein, one pair with very high affinity and the other with lower affinity Ca(2+)-binding sites. Also, only three sites are titratable in the wild-type protein because one site cannot be decalcified. Mutation of site 2 leaves the protein with only two titratable sites, while mutation of sites 1, 3, or 4 leave three titratable sites that are mostly filled with 3 Ca(2+) equiv added. The binding data further show that each of the single-site mutations Q2, Q3, and Q4 affects the affinities of at least one of the remaining sites. Mutation in either of sites 3 or 4 results in a protein with no high-affinity sites, indicating communication between the two high-affinity sites, most likely sites 3 and 4. Mutation in site 2 decreases the affinity of all three remaining sites, though still leaving two relatively high-affinity sites. The FTIR data support the conclusions from the binding data with respect to the number of titratable sites as well as the impact of each mutation on the affinities of the remaining sites. We conclude therefore that there is communication between all four Ca(2+)-binding sites. In addition, the Ca(2+) induced changes in the FTIR spectra for the wild-type and Q4 mutant are most similar, suggesting that the same three Ca(2+)-binding sites are being titrated, i.e., site 4 is the very high-affinity site under the conditions of the FTIR experiments.

Abstract
Several transplant programs have recently added cyclophosphamide (CyP) to their immune suppression protocols in an attempt to reduce intestinal graft rejection rates. The present study was undertaken to confirm the benefits of this drug in a murine small bowel transplant model. A short course of monotherapy with CyP 20 mg/kg per dose resulted in a mean survival time (MST) of 17.5 +/- 3.6 days, compared with a MST of 7.5 +/- 0.7 days in the untreated controls (P < 0.01). Cyclosporin A (CsA) 30 mg/kg per day produced comparable survival rates when used as monotherapy (MST: 14.2 +/- 1.3 days) or in combination with CyP 20 mg/kg per dose (MST: 21.3 +/- 5.1 days). Treatment with high dose CyP (40 mg/kg per dose) completely prevented graft loss in 8 of 10 animals (MST: 72.5 +/- 5.3 days, P < 0.01). However, adding CsA abrogated the induction of long-term survival achieved by CyP alone (MST: 23 +/- 0.4 days). These data have important implications for the use of CyP in clinical transplantation.
