Abstract
Our study aimed to investigate the effects of different dietary vitamin D (VD) combinations during the grower (1-32 d of age) and feed restriction (33-52 d of age) phases on growth performance. We also evaluated sternal morphology, mineralization, and related genes expression of bone metabolism as well as absorption of calcium and phosphorous in duodenal mucosa and kidney in Pekin ducks. During the grower phase, we used 2 VD regimes (Group A: 3,160 IU/kg VD3; Group B: 400 IU/kg VD3 + 69 μg/kg 25-OH-D3). Each dietary treatment had 50 replicate pens of 10 ducks per pen. During the feed restriction phase, 30 replicate pens selected from Group A and Group B, repetitively, were redivided into 5 different dietary VD regimes to form a 2 × 5 experimental design. Each group consisted of 6 replicates, each with 10 ducks. During the feed restriction phase, we evaluated 5 different dietary VD combinations were as follows: T1: 2,000 IU/kg VD3 ; T2: 5,000 IU/kg VD3; T3: 3,620 IU/kg VD3 + 34.5 μg/kg 25-OH-D3; T4: 2,240 IU/kg VD3 + 69 μg/kg 25-OH-D3; T5: 1,800 IU/kg VD3 + 80 μg/kg 25-OH-D3). Results showed that Group B combinations with T5 had a better growth performance and breast meat deposition (P < 0.1). Regardless of 5 dietary VD regimes during the feed restriction phase, Group B significantly increased (P < 0.05) 52 d sternal depth and tended to increase (P < 0.1) 52 d sternal defatted weight, ash content, and phosphate (P) content of ducks. A significant interactive effect (P < 0.05) was observed on the mRNA abundance of DMP1 and Sost1 as well as RANKL/OPG in sternum and of VDR in duodenal mucosa of ducks at 52 d of age between dietary VD combinations during 2 phases. These results indicated that dietary VD regimes during the grower phase could affect the effectiveness of dietary VD regimes during the feed restriction phases; Dietary VD combinations of both phases could affect the genes expression of bone formation and the absorption as well as reabsorption of calcium and phosphorus in duodenum and kidney.

Abstract
Epstein-Barr virus (EBV) is a global public health concern, as it is known to cause multiple diseases while also being etiologically associated with a wide range of epithelial and lymphoid malignancies. Currently, there is no available prophylactic vaccine against EBV. gB is the EBV fusion protein that mediates viral membrane fusion and participates in host recognition, making it critical for EBV infection in both B cells and epithelial cells. Here, we present a gB nanoparticle, gB-I53-50 NP, that displays multiple copies of gB. Compared with the gB trimer, gB-I53-50 NP shows improved structural integrity and stability, as well as enhanced immunogenicity in mice and non-human primate (NHP) preclinical models. Immunization and passive transfer demonstrate a robust and durable protective antibody response that protects humanized mice against lethal EBV challenge. This vaccine candidate demonstrates significant potential in preventing EBV infection, providing a possible platform for developing prophylactic vaccines for EBV.

Abstract
Objective: To explore the prognostic factors of extracellular NK/T cell lymphoma (ENKTL) treated with pegaspargase/L-asparaginase. Methods: The clinical data of 656 ENKTL patients diagnosed at 11 medical centers in the Huaihai Lymphoma Working Group from March 2014 to April 2021 were retrospectively analyzed. The patients were randomly divided into two groups: a training set (460 cases) and a validation set (196 cases) at 7∶3, and the prognostic factors of the patients were analyzed. A prognostic scoring system was established, and the predictive performance of different models was compared. Results: Patients' median age was 46 (34, 57) years, with 456 males (69.5% ) and 561 nasal involvement (85.5% ). 203 patients (30.9% ) received a chemotherapy regimen based on L-asparaginase combined with anthracyclines, and the 5-year overall survival rate of patients treated with P-GEMOX regimen (pegaspargase+gemcitabine+oxaliplatin) was better than those treated with SMILE regimen (methotrexate+dexamethasone+cyclophosphamide+L-asparaginase+etoposide) (85.9% vs 63.8% ; P=0.004). The results of multivariate analysis showed that gender, CA stage, the Eastern Cooperative Oncology Group performance status (ECOG PS) score, HGB, and EB virus DNA were independent influencing factors for the prognosis of ENKTL patients (P<0.05). In this study, the predictive performance of the prognostic factors is superior to the international prognostic index, Korean prognostic index, and prognostic index of natural killer lymphoma. Conclusion: Gender, CA stage, ECOG PS score, HGB, and EB virus DNA are prognostic factors for ENKTL patients treated with pegaspargase/L-asparaginase.

Abstract
Objective: To investigate the clinical and pathological features of primary gastric (gastrointestinal)-type mucoglandular lesions of the endometrium. Methods: Eight cases of primary gastric (gastrointestinal)-type mucoglandular lesions of endometrium diagnosed between 2014 to 2022 were retrieved from pathology archives of the Obstetrics and Gynecology Hospital Affiliated to Fudan University, Shanghai, China. The clinical history, pathological sections and follow-ups were analyzed. Results: The eight patients ranged in age from 35 to 67 years, with an average age of 55.5 years. Seven patients were examined for high-risk human papillary virus (HPV) before operation. Only one of them was positive for high-risk HPV52. No cervical mucinous lesions were found in any of the patients. Two cases were invasive gastric (gastrointestinal)-type adenocarcinoma, 2 cases were benign gastric (gastrointestinal)-type mucinous metaplasia, and the other 4 cases were atypical gastric (gastrointestinal)-type mucinous gland hyperplasia. Microscopically, tumor cells showed mucous epithelium with gastrointestinal differentiation. Immunophenotyping showed that MUC6 was diffusely or focally positive in 5 cases, CK20 and CDX2 were positive in 3 cases. And p16 was negative or focally positive in 5 cases and strongly positive in 1 case. ER was expressed in both benign and atypical lesions, and weakly positive or negative in the invasive adenocarcinoma. p53 showed mutant expression in one case and wild-type expression in the rest. HPV in situ hybridization was negative. Conclusions: Primary gastric (gastrointestinal)-type mucoglandular lesions of the endometrium show various forms of gastrointestinal differentiation, which are high-risk HPV independent. Morphology combined with immunohistochemistry is helpful for the diagnosis, which can only be made on exclusion of cervical gastrointestinal glandular lesion, gastrointestinal metastatic carcinoma and the mucinous subtype of endometrioid carcinoma.

Abstract
The field null configuration of a poloidal magnetic field is one of the critical conditions for achieving Ohmic breakdown during the initial discharge of a new tokamak. The issue of the Ohmic breakdown on the NanChang Spherical Tokamak (NCST) is still not solved satisfactorily although plasma currents of about 2 kA were found. Hence, a removable three-dimensional magnetic probe (RTMP) system consisting of 25 magnetic probes was designed, calibrated, and constructed on the NCST to evaluate the field null inside a vacuum vessel. After repeated tests, the RTMP system exhibited outstanding performance in terms of accuracy and stability with errors of about 1%. Meanwhile, the RTMP system successfully measured the toroidal field (TF) coil ripples at the magnetic axis. During experiments, the stray field arising from the TF coil implied a strong link between the flexible connection of the TF coil and the Ohmic breakdown on the NCST. After the field null was effectively modified by using a new flexible connection of the TF coil and controlling the induced current in the poloidal field coil, the NCST tokamak reproducibly obtained 20 kA plasma current with the limiter configuration during the plasma current flat-top phase.

Abstract
Objective: To screen and perform preliminary clinical validation of biomarkers of activity based on positron emission tomography/computed tomography (PET-CT) and transcriptomics in sputum-negative pulmonary tuberculosis lesion tissue. Methods: Nine patients with sputum-negative pulmonary tuberculosis treated surgically at the Shanghai Public Health Clinical Center for Thoracic Surgery from January 1, 2017 to December 31, 2019 were retrospectively collected as the discovery group, including four males and five females, aged 20-57 years (mean 36 years). All of the patients underwent PET-CT scanning before surgery, and the resected specimens were postoperatively classified according to preoperative PET-CT. The resected specimens were divided into areas with increased fluorodeoxyglucose (FDG) metabolism (SUVmax>3) and areas with normal FDG metabolism (SUVmax ≤ 3) according to the preoperative PET-CT performance. After sample processing, total RNA was extracted from the tissues of different regions, and then whole gene transcriptome sequencing was performed. Bioinformatics analysis of the two sets of data was performed to discover the expression profiles of the differences in whole gene transcriptome data between the two regions and to screen for candidate biomarkers. Eighty patients with sputum-negative pulmonary tuberculosis admitted to Shanghai Public Health Clinical Center from January 1, 2019 to January 1, 2021 were retrospectively collected as the validation group, including 37 males and 43 females, aged 20-62 years, with an average age of 39 years. The validation group was divided into a group with increased SUV (n=40) and a group without lesions on CT imaging (n=40). Enzyme-linked immunosorbent assay (ELISA) was used to determine the protein levels of candidate biomarkers in the peripheral plasma of patients. The effect of biomarkers was assessed using subject operating characteristic (ROC) curves. Student's t-test was used to determine whether the difference in protein levels between the two groups was statistically significant. Results: Bioinformatics analysis revealed that the expression levels of C1QB, CCL19, CCL5 and HLA-DMB correlated with the metabolic activity of sputum-negative tuberculosis lesion tissue. Further screening and validation by the validation group confirmed that the difference in C1QB protein levels in the peripheral plasma of patients was statistically significant between the group with increased SUV and the group without lesions on CT imaging [(3.55±0.34) mg/L vs. (2.75±0.21) mg/L, t=4.12, P<0.001]. And the ROC curve showed that the area under the curve for C1QB protein levels was 0.731, which had potential clinical value. Conclusion: The C1QB protein level can be used to assess the activity of lesions in patients with sputum-negative tuberculosis and is a potential biomarker.

Abstract
BACKGROUND Corona virus disease 2019 (COVID-19) is a severe acute respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Different pooling testing strategies have been applied for the detection of SARS-CoV-2. However, the discrepancies among different pooling strategies are still to be explored. METHODS The aim of this study was to evaluate the two pooling strategies of collecting respiratory specimens for the detection of SARS-CoV-2 RNA. Two groups of five-sample pools were prepared to evaluate the impact of sample pooling and pooled sampling on test sensitivity, respectively. Viral RNA of coronavirus was extracted with the automation system. The N and ORF1ab genes of SARS-CoV-2 RNA were detected with real-time reverse-transcription PCR. The turnaround time of SARS-CoV-2 testing was analyzed before and after the implement of pooled sampling. RESULTS The pooled sampling displayed advantages in assay sensitivity over the sample pooling. The implementation of pooled sampling significantly shortened the turnaround time of SARS-CoV-2 testing. CONCLUSIONS The pooled sampling is an efficient and economical strategy for SARS-CoV-2 detection during the periods of high screening demand in low-prevalence areas.

Abstract
Objective: To investigate the role and mechanism of DNA methylation in Mycobacterium tuberculosis (MTB lysate) -induced downregulation of interleukin-6 receptor(IL-6R) expression in CD4+T cells. Methods: A prospective study was conducted. Bisulfite sequencing (BSP) was applied to determine the methylation levels of CpG island in IL-6R promoter region and 3'untranslated region (3'UTR) region in CD4+T cells from peripheral blood mononuclear cells (PBMC) of control group (healthy person, n=10) and TB group (tuberculosis patients, n=10) in Shenzhen Third People's Hospital between 2019 and 2020. Quantitative reverse transcription-PCR (RT-qPCR) and Western blotting were used to detect the expression of IL-6R, DNMT1, DNMT3A and DNMT3B in MTB lysate-stimulated CD4+T cells and Jurkat E6-1 cells. Furthermore, PBMC in control group and Jurkat E6-1 cells activated by anti-CD3/CD28 antibody were stimulated by MTB lysates to detect the methylation levels of CpG island and IL-6R and DNMT expression. Transcriptional activity of differently methylation regions of IL-6R 3'UTR was detected by using luciferase reporter gene system. Results: IL-6R expression in TB group was lower than that in control group, but DNMT1 and DNMT3B expressions were higher than those in control group in CD4+T cells isolated from PBMC. There was no significant difference in the methylation rate of IL-6R promoter CpG island of CD4+T cells between control and TB group. However, the methylation rates of CpG island in 3'UTR region were significantly higher (P<0.001) in TB (69.5%±3.4%), compared with control (54.3%±4.7%). Besides, IL-6R expression was lower than unstimulated, while DNMT1 and DNMT3B expression was higher than unstimulated after MTB lysate-stimulation of activated control PBMC in vitro. The methylation rate of CpG island in IL-6R 3'UTR region of CD4+T cells increased from 58.8%±11.6% to 79.4%±10.9% (P<0.001) after MTB lysate-stimulated PBMC of the control. The same results were observed in the MTB lysate-stimulated CD4+T cells isolated from PBMC in control and Jurkat E6-1 cell line. Furthermore, IL-6R expression after co-treatment of the DNA methyltransferase inhibitor decitabine (5-aza) with MTB lysate was higher than that stimulated by MTB lysate alone. In addition, the methylation levels of CpG islands in the 3' UTR region of IL-6R were lower than those stimulated by MTB lysates alone after co-treatment of the DNA methyltransferase inhibitor decitabine (5-aza) with MTB lysates. The transcriptional activity of the fully unmethylated IL-6R 3'UTR CpG island reporter gene was higher than that of the fully methylated IL-6R 3'UTR CpG island. Conclusions: MTB lysates stimulation inhibited IL-6R expression transcriptionalely as well as on the protein level by inducing hypermethylation of CpG island in IL-6R 3'UTR region of CD4+T cells. The hypermethylation of CpG island in IL-6R 3'UTR region of CD4+T cells induced by MTB may be related to the increased expression of DNMT1 and DNMT3B.

Abstract
Objective: To develop a predictive model for pathologic complete response (pCR) of ipsilateral supraclavicular lymph nodes (ISLN) after neoadjuvant chemotherapy for breast cancer and guide the local treatment. Methods: Two hundred and eleven consecutive breast cancer patients with first diagnosis of ipsilateral supraclavicular lymph node metastasis who underwent ipsilateral supraclavicular lymph node dissection and treated in the Breast Department of Henan Cancer Hospital from September 2012 to May 2019 were included. One hundred and forty two cases were divided into the training set while other 69 cases into the validation set. The factors affecting ipsilateral supraclavicular lymph node pCR (ispCR)of breast cancer after neoadjuvant chemotherapy were analyzed by univariate and multivariate logistic regression analyses, and a nomogram prediction model of ispCR was established. Internal and external validation evaluation of the nomogram prediction model were conducted by receiver operating characteristic (ROC) curve analysis and plotting calibration curves. Results: Univariate logistic regression analysis showed that Ki-67 index, number of axillary lymph node metastases, breast pCR, axillary pCR, and ISLN size after neoadjuvant chemotherapy were associated with ispCR of breast cancerafter neoadjuvant chemotherapy (P<0.05). Multivariate logistic regression analysis showed that the number of axillary lymph node metastases (OR=5.035, 95%CI: 1.722-14.721, P=0.003), breast pCR (OR=4.662, 95%CI: 1.456-14.922, P=0.010) and ISLN size after neoadjuvant chemotherapy (OR=4.231, 95%CI: 1.194-14.985, P=0.025) were independent predictors of ispCR of breast cancer after neoadjuvant chemotherapy. A nomogram prediction model of ispCR of breast cancer after neoadjuvant chemotherapy was constructed using five factors: number of axillary lymph node metastases, Ki-67 index, breast pCR, axillary pCR and size of ISLN after neoadjuvant chemotherapy. The areas under the ROC curve for the nomogram prediction model in the training and validation sets were 0.855 and 0.838, respectively, and the difference was not statistically significant (P=0.755). The 3-year disease-free survival rates of patients in the ispCR and non-ispCR groups after neoadjuvant chemotherapy were 64.3% and 54.8%, respectively, with statistically significant differences (P=0.024), the 3-year overall survival rates were 83.8% and 70.2%, respectively, without statistically significant difference (P=0.087). Conclusions: Disease free survival is significantly improved in breast cancer patients with ispCR after neoadjuvant chemotherapy. The constructed nomogram prediction model of ispCR of breast cancer patients after neoadjuvant chemotherapy is well fitted. Application of this prediction model can assist the development of local management strategies for the ipsilateral supraclavicular region after neoadjuvant chemotherapy and predict the long-term prognosis of breast cancer patients.

Abstract
Epstein–Barr virus (EBV) is a human herpesvirus that is common among the global population, causing an enormous disease burden. EBV can directly cause infectious mononucleosis and is also associated with various malignancies and autoimmune diseases. In order to prevent primary infection and subsequent chronic disease, efforts have been made to develop a prophylactic vaccine against EBV in recent years, but there is still no vaccine in clinical use. The outbreak of the COVID-19 pandemic and the global cooperation in vaccine development against SARS-CoV-2 provide insights for next-generation antiviral vaccine design and opportunities for developing an effective prophylactic EBV vaccine. With improvements in antigen selection, vaccine platforms, formulation and evaluation systems, novel vaccines against EBV are expected to elicit dual protection against infection of both B lymphocytes and epithelial cells. This would provide sustainable immunity against EBV-associated malignancies, finally enabling the control of worldwide EBV infection and management of EBV-associated diseases.

Abstract
The coronavirus disease pandemic of 2019 (COVID-19) caused by the novel SARS-CoV-2 coronavirus resulted in economic losses and threatened human health worldwide. The pandemic highlights an urgent need for a stable, easily produced, and effective vaccine. SARS-CoV-2 uses the spike protein receptor-binding domain (RBD) to bind its cognate receptor, angiotensin-converting enzyme 2 (ACE2), and initiate membrane fusion. Thus, the RBD is an ideal target for vaccine development. In this study, we designed three different RBD-conjugated nanoparticle vaccine candidates, namely, RBD-Ferritin (24-mer), RBD-mi3 (60-mer), and RBD-I53-50 (120-mer), via covalent conjugation using the SpyTag-SpyCatcher system. When mice were immunized with the RBD-conjugated nanoparticles (NPs) in conjunction with the AddaVax or Sigma Adjuvant System, the resulting antisera exhibited 8- to 120-fold greater neutralizing activity against both a pseudovirus and the authentic virus than those of mice immunized with monomeric RBD. Most importantly, sera from mice immunized with RBD-conjugated NPs more efficiently blocked the binding of RBD to ACE2 in vitro, further corroborating the promising immunization effect. Additionally, the vaccine has distinct advantages in terms of a relatively simple scale-up and flexible assembly. These results illustrate that the SARS-CoV-2 RBD-conjugated nanoparticles developed in this study are a competitive vaccine candidate and that the carrier nanoparticles could be adopted as a universal platform for a future vaccine development.

Abstract
Superlubricity between a cone-shaped (sharp) silicon tip and graphite remains a challenge in the nanotribology field. In this paper, an efficient method of achieving superlubricity between a cone-shaped silicon tip and graphite was proposed. Graphite nanoflakes were transferred onto the silicon tip by repeatedly rubbing against the scratches produced by nanolithography on a graphite surface. The superlubricity between the graphite nanoflakes-wrapped tip and highly oriented pyrolytic graphite (HOPG) was attained, and the friction coefficient was reduced to 0.0007. At low normal loads, the frictional force was small and showed a strong correlation with the sliding angle, but as the normal load increased, this dependence gradually decreased. It was firstly found that the transferred graphite nanoflakes on the contact zone of the silicon tip could be transformed into amorphous carbon layers induced by the shear force and high pressure during the superlubricity test process.

Abstract
Tuberculosis (TB) is the leading infectious cause of mortality worldwide, especially in developing countries. However, effective means for TB diagnosis, especially for bacillus-negative (Bn) TB laboratory diagnosis, are urgently needed. In the present study, serum IgG from each tuberculosis patients and healthy controls was purified using affinity chromatography. The samples were then analyzed using mass spectrometry (MS) and ultraperformance liquid chromatography (UPLC) methods. We quantitatively assessed the changes of serum IgG galactosylation in 567 human serum samples including 377 pulmonary TB patients and 190 healthy donors (HDs). We found significantly more agalactosylated (G0) vs monogalactosylated (G1) and digalactosylated (G2) N-glycans of IgG in TB patients, including smear-negative TB patients, than in HDs. The detection rate of TB diagnostic performance by MS for IgG-Gal ratio G0/(G1 + G2 × 2) is 90.48% for bacillus-positive (Bp) and 73.16% for Bn TB patients. Further, combination of MS method with other routine laboratory TB diagnostic methods significantly increased the detection rate to 91.01%-98.39%. Similar results were observed in Mycobacterium tuberculosis (M. tb) infection mouse models. The decrease in galactosylation of IgG in TB patients was also qualitatively confirmed using specific lectin blot assay. Using the above techniques, we can discriminate the content of IgG G0 with terminal N-acetylglucosamine and IgG-Gal ratio G0/(G1 + G2 × 2) between TB patients and HDs. Our data suggest that quantitative analysis of serum-based IgG-Gal ratio G0/(G1 + G2 × 2) could be used for TB auxiliary diagnosis with high effectiveness and feasibility and its combination with other routine laboratory TB diagnostic methods could remarkably improve the detection rate.

Abstract
This work concerns noise reduction for one-dimensional spectra in the case that the signal is corrupted by an additive white noise. The proposed method starts with mapping the noisy spectrum to a partial circulant matrix. In virtue of singular-value decomposition of the matrix, components belonging to the signal are determined by inspecting the total variations of left singular vectors. Afterwards, a smoothed spectrum is reconstructed from the low-rank approximation of the matrix consisting of the signal components only. The denoising effect of the proposed method is shown to be highly competitive among other existing nonparametric methods, including moving average, wavelet shrinkage, and total variation. Furthermore, its applicable scenarios in precision storage-ring mass spectrometry are demonstrated to be rather diverse and appealing.

Abstract
Background Osteoporosis (OP) is common in patients with chronic obstructive pulmonary disease (COPD). The relationship between OP and COPD has been primarily studied in male patients, and few reports are available in postmenopausal women. Objective The purpose of this study was to investigate the association between bone mineral density (BMD) and COPD in postmenopausal women. Methods This cross-sectional study included 133 clinically stable female ex-smokers with confirmed COPD, and 31 age-matched "ex-smoker" female controls. We analyzed groups according to their airway obstruction category. BMD was measured on dual-energy X-ray absorptiometry images of the left femoral neck. Results Patients with COPD had lower T-scores and higher prevalence of osteopenia/OP than the control group. In the COPD group, the airway obstruction category was significantly associated with the T-score after adjustment for confounders. Multivariate logistic regression analysis showed COPD was an independent marker for increased risk of osteopenia/OP in postmenopausal women. Conclusions COPD and airway obstruction category were strongly related to BMD. Postmenopausal women with COPD, especially those with severe airway obstruction, had a higher prevalence rate and a higher risk of osteopenia and OP than female controls without COPD.

Abstract
Objective: To understand the characteristics on major strain subtypes of hepatitis C virus among HIV/HCV co-infected patients, so as to explore the molecular transmission clusters and related risk factors of HCV strains. Methods: A total of 336 newly reported HIV-infected patients were diagnosed as HIV/HCV co-infection in Dehong Dai and Jingpo autonomous prefecture (Dehong) in 2016. We used Nested PCR to amplify CE1 and NS5B genes among 318 samples with plasma levels above 200 μl, before using the combining phylogenetic tree and constructing molecular propagation network method to analyze the related data. Results: A total of 267 HIV/HCV co-infection patients who had met the HCV genotyping requirements were screened the gene subtypes were diversified. Among these genotypes, proportions of 3b, 6n, 6u, 1a, 3a and other subtypes appeared as 32.6% (87/267), 18.4% (49/267), 15.7%(42/267), 13.1%(35/267), 11.2%(30/267) and 9.0%(24/267) respectively. Molecular transmission network of five major HCV genotypes was constructed with a clustering rate of 39.1% (95/243). The clustering rate of subtype 1a was the highest, as 71.4% (25/35). Results from the multivariate logistic regression showed that ethnic minorities other than the Yi and Jingpo (vs. the Han, OR=0.17, 95%CI: 0.04-0.71), the married spouses (vs. the unmarried, OR=0.42, 95%CI: 0.18-0.94), the 6n and 3a subtype (vs. the 3b subtype, OR=0.34, 95%CI: 0.12-0.95; OR=0.22, 95%CI: 0.05-0.93) were more difficult to form transmission clusters. However, the 6u and 1a subtype (vs. the 3b subtype, OR=3.10, 95%CI: 1.21-7.94; OR=4.00, 95%CI: 1.32-12.11) seemed more likely to form the transmission clusters. Conclusion: Ethnicity, marital status and genetic subtypes were factors significantly associated with the formation of transmission clusters related to the major HCV gene subtypes among newly reported HIV/HCV co-infection in Dehong.

Abstract
BACKGROUND It is challenging to distinguish intestinal tuberculosis from Crohn's disease due to dynamic changes in epidemiology and similar clinical characteristics. Recent studies have shown that polymorphisms in genes involved in the interleukin (IL)-23/IL-17 axis may affect intestinal mucosal immunity by affecting the differentiation of Th17 cells. AIM To investigate the specific single-nucleotide polymorphisms (SNPs) in genes involved in the IL-23/IL-17 axis and possible pathways that affect susceptibility to intestinal tuberculosis and Crohn's disease. METHODS We analysed 133 patients with intestinal tuberculosis, 128 with Crohn's disease, and 500 normal controls. DNA was extracted from paraffin-embedded specimens or whole blood. Four SNPs in the IL23/Th17 axis (IL22 rs2227473, IL1β rs1143627, TGFβ rs4803455, and IL17 rs8193036) were genotyped with TaqMan assays. The transcriptional activity levels of different genotypes of rs2227473 were detected by dual luciferase reporter gene assay. The expression of IL-22R1 in different intestinal diseases was detected by immunohistochemistry. RESULTS The A allele frequency of rs2227473 (P = 0.030, odds ratio = 0.60, 95% confidence interval: 0.37-0.95) showed an abnormal distribution between intestinal tuberculosis and healthy controls. The presence of the A allele was associated with a higher IL-22 transcriptional activity (P < 0.05). In addition, IL-22R1 was expressed in intestinal lymphoid tissues, especially under conditions of intestinal tuberculosis, and highly expressed in macrophage-derived Langhans giant cells. The results of immunohistochemistry showed that the expression of IL-22R1 in patients with Crohn's disease and intestinal tuberculosis was significantly higher than that in patients with intestinal polyps and colon cancer (P < 0.01). CONCLUSION High IL-22 expression seems to be a protective factor for intestinal tuberculosis. IL-22R1 is expressed in Langhans giant cells, suggesting that the IL-22/IL-22R1 system links adaptive and innate immunity.

Abstract
Objective: To evaluate the non-carcinogenic health risk of heavy metals (As, Cd, Cr, Cu, Mn, Pb and Zn) in residential indoor dust for young children around an e-waste dismantling area in South China. Methods: A village around an e-waste dismantling area in South China was selected as a research site in October 2016. Convenience sampling method was used to select 36 houses in the village and 36 dust samples were collected by vacuum cleaner. The concentrations of heavy metals (Cd, Cr, Cu, Mn, Pb and Zn) in each sample were determined and expressed by the average value. Non-carcinogenic health risk assessment was conducted using the US Environmental Protection Agency (EPA) Health Risk Assessment (HRA) model, the American Toxicology and Disease Registry (ATSDR) Target-organ Toxicity Dose (TTD) approach and the ATSDR Binary Weight-of-Evidence (BINWOE) model. Results: The mean ± SD of concentrations of As, Cd, Cr, Cu, Mn, Pb and Zn were (48.90±33.91), (5.95±3.89), (173.57±580.37), (412.71±1 190.00), (612.82±540.70), (297.41±293.22) and (1 052.81±1 156.48) mg/kg, respectively. The HI value of TTD (2.670) and BINWOE (2.933) were higher than the safety threshold of EPA recommended non-carcinogenic health risk. The HI value of TTD and BINWOE were 1.93 and 2.12 times higher than the HI value of HRA (1.386). Conclusion: There was non-carcinogenic health risk of heavy metals (As, Cd, Cr, Cu, Mn, Pb and Zn) via residential indoor dust around the e-waste dismantling area for local children.

Abstract
Objective: To investigate the long term efficacy of COPADM regimen in the treatment of Burkitt lymphoma (BL). Methods: The clinical data of 39 patients with BL from April 2006 to June 2017 were retrospectively analyzed. According to different chemotherapy regimens, the patients were divided into COPADM group and control group. Results: ①Of 39 BL patients, 26 were male and 13 female. The median age was 30 (11-63) years old, including 25 younger than 40 and 14 older than 40. Among them, 33 patients were in stage Ⅲ-Ⅳ, 13 patients had B symptoms and 25 patients were IPI score≥3. ② Twenty patients treated with COPADM regimen (COPADM group), the 3 year overall survival (OS) and progression-free survival (PFS) were (83.5±2.6)% and (73.2±3.1)%, respectively. Nineteen patients in the control group had a 3-year OS and EFS of (47.4±2.4) % and (42.1±2.4) %, respectively. There were significant differences in OS and EFS between the two groups (all P<0.001). ③Of the 20 patients in COPADM group, 12 were younger patients (age≤40 years), their 3-year OS and EFS were (93.7±3.9)% and (83.3±5.4)%, respectively. The other 8 patients were older than 40 years old, and their 3-year OS and EFS were (48.3±8.5) %, (37.6±6.0) %, respectively. Both OS and EFS in younger patients was significantly better than older patients (P=0.004, P=0.045). ④ There were 24 patients treated with combination of Rituximab, their 3-year OS and EFS were (73.9±9.2)% and (69.9±9.6)%, respectively. The other 15 patients were treated without Rituximab, and their 3-year OS and EFS were (51.3±13.3) % and (38.1±12.9) %, respectively. There were significant differences in OS and EFS between the two groups (P=0.042, P=0.008). Conclusion: COPADM regimen may improve the efficacy of BL. COPADM combined with Rituximab enables BL patients with greater benefit. The prognosis is significantly worse in patients older than 40 years old than in those less than 40 years old.

Abstract
A miniature sensor for detection of aggregation-induced-emission (AIE) molecules is proposed in this work. The sensing head is fabricated by use of hollow-core photonic crystal fiber with a core diameter of about 4.8 μm. The cladding holes are sealed with a fusion splicing technique, and the central hole remains open to allow the filtration of solution with AIE molecules. When the solution is excited by an ultraviolet lamp, the fluorescence is received by a fiber-optic spectrometer. The fluorescence intensity is associated with the concentration of AIE molecules and the infiltrated-core length. In the whole process of the experiments, the output-peak wavelength is stable, which indicates that the existing forms of AIE particles are stable, and the fluorescence reabsorption can be neglected. The experimental results obtained are in accordance with traditional microplate-spectrophotometer methods. The most exciting result is that the amount of sample measured can be as low as 0.36 nL, which allows the detection of AIE molecules at only 0.02 pmol. In addition, the miniature sensor was successfully applied to the detection of an AIE-based bioprobe for evaluating the activity of the dipeptidyl-peptidase 4 (DPP-4) inhibitor sitagliptin with an IC50 of 59.80 ± 3.06 nM. The advantages of small device size and nanoliter-scale sample volumes suggest that the proposed sensor is promising for many biosensing applications.

Abstract
BACKGROUND The diagnosis of active pulmonary tuberculosis (TB) remains a challenge in clinic, especially for sputum negative pulmonary TB. Bronchoalveolar lavage fluid (BALF) has higher sensitivity than sputum for detection of Mycobacterium tuberculosis (Mtb). However, bronchoscopy is invasive and costly, and not suitable for all patients. In order to make TB patients get more benefit from BALF for diagnosis, we explore which indicator might be used to optimize the choice of bronchoscopy. METHODS A total of 1539 sputum-smear-negative pulmonary TB suspects who underwent bronchoscopy were recruited for evaluation. The sensitivity, specificity and accuracy of Mtb detection in sputum and BALF were compared. Odds ratios and 95% confidence intervals were used to assess variables that associated with positive acid-fast bacilli (AFB) smear, Mtb culture and nucleic acid amplification test (NAAT) of BALF in sputum-negative and non-sputum-producing pulmonary TB suspects. RESULTS BALF has significantly higher sensitivity (63.4%) than sputum (43.5%) for Mtb detection by culture and NAAT. 19.7% (122/620) sputum-negative and 40.0% (163/408) non-sputum-producing suspects had positive bacteriological results in BALF. Among sputum-negative and non-sputum-producing pulmonary TB suspects, the positivity of Mtb detection in BALF is associated with a younger age, the presence of pulmonary cavities and a positive result of interferon-gamma release assay (IGRA). Sputum-negative patients under 35 years old with positive IGRA and pulmonary cavity had 84.8% positivity of Mtb in BALF. CONCLUSIONS Our study indicated that combination of age, the presence of pulmonary cavity, and the result of IGRA is useful to predict the positivity of Mtb detection in BALF among sputum-negative and non-sputum producing pulmonary TB suspects. Those who are under 35 years old, positive for the presence of pulmonary cavity and IGRA, should undergo bronchoscopy to collect BAFL for Mtb tests, as they have the highest possibility to get bacteriologically confirmation of TB.

Abstract
Objective: To understand the epidemiological characteristics of newly reported HIV infections in Chinese and Burmese residents during 2012-2016 in Dehong Dai and Jingpo Autonomous Prefecture of Yunnan province (Dehong) and to provide evidence for the development of related programs on prevention and control. Methods: All the HIV infections who were newly reported during 2012-2016 in Dehong, were recruited as the study subjects, with epidemiological characteristics of the cases analyzed by using the software SPSS 22.0. Results: A total of 5 692 HIV infections were newly reported between 2012 and 2016 (including 5 592 in this study), in which the Chinese patients accounted for 43.3% (2 419) and the rest 56.7% (3 173) were Burmese. Differences in age, gender and other social characteristics of these newly reported HIV infections were statistically significant between the Chinese and the Burmese (all p-values <0.05). Most cases were males and between the age of 20-49 years old. Other characteristics of the patients would include: having had primary school education, married, being farmers, and with CD(4)(+)T cells counts ≥350 cells/μl. HIV infection was mainly transmitted through sexual contact among the Chinese patients but through injecting drug use among the Burmese patients. Conclusions: Epidemiological characteristics of the newly reported HIV infections were different between the Chinese and the Burmese, between 2012 and 2016 in Dehong. Targeted prevention and control programs should be taken.

Abstract
Objective: To investigate the application and best cut-off value of Chinese version of Addenbrooke's cognitive examination-Ⅲ(ACE-Ⅲ) in type 2 diabetes mellitus (T2DM) patients with mild cognitive impairment. Methods: A total of 18 T2DM patients with normal cognitive function (NCI group) and 40 T2DM patients with mild cognitive impairment (MCI group) treated in outpatient clinic or ward of Department of Neurology and Endocrinology in Fujian Medical University Union Hospital between January 2015 and February 2016 were enrolled. Mini Mental State Scale (MMSE), Montreal cognitive assessment scale (MoCA), Activity of Daily Living Scale (ADL) and the Chinese version of ACE-Ⅲ were used to assess cognitive function of subjects and to assess the value of ACE-Ⅲ in the diagnosis of T2DM patients with mild cognitive impairment. Results: The Cronbach's alpha of the Chinese version of ACE-Ⅲ is 0.768. ACE-Ⅲ and MoCA were correlative (r=0.768, P<0.001). The area under the receiver operating characteristic (ROC) curve for ACE-Ⅲ was 0.906 (95%CI: 0.827-0.985). When the cut-off value for diagnosis was 87.5, the maximum Youden index was 0.769, with a sensitivity of 0.825 and a specificity of 0.944. Patients in MCI group got a lower score in the sub-items of attention/orientation, memory, verbal fluency, language and visual space of ACE-Ⅲ compared to those in NCI group, and the differences were statistically significant (t=5.336, P<0.001; t=5.530, P<0.001; t=4.556, P<0.001; t=5.301, P<0.001; t=2.821, P=0.008). Conclusion: The Chinese version of ACE-Ⅲ had good internal consistency reliability, and it could effectively detect impairment of general cognitive function and single cognitive domains in T2DM patients.

Abstract
目的 探讨手术联合化疗与单纯化疗对原发胃弥漫大B细胞淋巴瘤(PGDLBCL)患者生存的影响,并分析化疗过程中联合应用利妥昔单抗(R)对其预后的影响。 方法 回顾性分析83例PGDLBCL患者的临床资料,并分析外科手术及利妥昔单抗对患者生存的影响。 结果 83例患者中男43例,女40例,中位年龄52 (20~76)岁,中位随访时间为36 (4~59)个月。手术联合化疗组(40例)和单纯化疗组(43例)患者的5年总生存(OS)率分别为68.4%、85.9%(P=0.117),疾病无进展生存(PFS)率分别为66.7%、82.6%(P=0.258),差异均无统计学意义。手术联合化疗患者中R-CHOP方案组(23例)和CHOP方案组(17例)患者的5年OS率分别为73.6%、64.2%(P=0.113),PFS率分别为71.2%、62.5%(P= 0.147);单纯化疗患者中R-CHOP方案组(24例)和CHOP方案组(19例)患者的5年OS率分别为85.7%、83.5%(P=0.152),PFS率分别为83.4%、81.8%(P=0.307)。单纯化疗组和手术联合化疗组Lugano分期早期(Ⅰ~Ⅱ1期)患者的5年OS率分别为86.4%、78.7%,差异无统计学意义(P=0.283);晚期(Ⅱ2~Ⅳ期)患者分别为74.6%、58.5%,差异有统计学意义(P=0.040)。多因素分析显示IPI评分是影响预后的独立因素(RR=0.370,95% CI 0.089~3.537,P=0.015)。 结论 单纯化疗或手术联合化疗对PGDLBCL患者长期生存的影响差异无统计学意义,但由于手术可能造成患者生存质量的下降,因此对于无手术指征者更倾向于推荐单纯化疗。本研究中利妥昔单抗的联合应用未能使大部分这类患者的生存显著获益,但这需要进一步多中心、大样本的研究来证实。

Abstract
Masses of ^{52g,52m}Co were measured for the first time with an accuracy of ∼10 keV, an unprecedented precision reached for short-lived nuclei in the isochronous mass spectrometry. Combining our results with the previous β-γ measurements of ^{52}Ni, the T=2, J^{π}=0^{+} isobaric analog state (IAS) in ^{52}Co was newly assigned, questioning the conventional identification of IASs from the β-delayed proton emissions. Using our energy of the IAS in ^{52}Co, the masses of the T=2 multiplet fit well into the isobaric multiplet mass equation. We find that the IAS in ^{52}Co decays predominantly via γ transitions while the proton emission is negligibly small. According to our large-scale shell model calculations, this phenomenon has been interpreted to be due to very low isospin mixing in the IAS.

Abstract
OBJECTIVE To investigate the effects of iron chelation therapy on hematopoietic reconstitution and related complications of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with myelodysplastic syndrome (MDS). METHODS Various clinical parameters were analyzed retrospectively in 57 MDS patients with iron overload who received allo-HSCT. According to the level of serum ferritin (SF) before transplantation divided patients into two groups: the effective treatment group (SF<1 000 μg/L) and iron overload group (SF≥1 000 μg/L). RESULTS ①30/57 cases were received iron chelation treatment, 27/57 patients didn' t received iron chelating therapy before transplantation. 19/30 cases were in the effective treatment group, and the median SF level before transplantation was 561 (223-846) μg/L. 11/30 cases were in the iron overload group, and the median SF level before transplantation was 1 262 (1 100-2 352) μg/L. The median SF level was 1 540 (1 320-3 112) μg/L of 27 patients didn't received iron chelating therapy before transplantation. ② The rate of fully-engraftment in the effective treatment group and iron overload group was 19 cases (100.0% ) and 34 cases (89.5% ), myeloid reconstitution of 12(10-18) and 12(11-30) days respectively (P=0.441), and platelet reconstitution of 13(12-30) and 15 (10-32) days respectively (P=0.579). ③The infection risk rate of the effective treatment group was less than iron overload group [36.8% (7/19) vs 82.4% (28/34), P=0.002]. ④The incidence of aGVHD in effective treatment group was less than iron overload group [26.3%(5/19) vs 64.7%(22/34), P= 0.010]. All patients of the effective treatment group were Ⅰ/Ⅱ degree. 16 cases were Ⅰ/Ⅱ degree and 6 cases were Ⅲ/Ⅳ degree in the iron overload group. ⑤ 6 cases of iron overload group accepted iron chelation treatment early post-transplantation, and SF level decreased from 2 870 (2 205-3 580) μg/L to 1 270 (1 020-1 650) μg/L. ⑥The difference of median disease-free survival time between the effective treatment group and iron overload group was not statistically significant [28.9 (0.3-89.5) months vs 21.2(0.1-81.0) months, χ(2)=3.751, P=0.053]. CONCLUSIONS Iron overload obviously increased transplant-related complications, and effective iron chelation therapy before transplantation significantly decreased the incidence of infection and degree of aGVHD, thereby reduced the non-relapse mortality in patients with MDS.

Abstract
OBJECTIVE Primary osteoporosis is a progressive bone disease that is characterized by a decrease in bone mass and density which can lead to an increased risk of fracture. Most of present treatments are effective for osteoporosis, but have limitations and side-effects. With the aging of the world population is increasing, the incidence of osteoporosis is rising. Therefore, the purpose of this study was to identify new candidate genes used as the therapeutic targets of primary osteoporosis. MATERIALS AND METHODS In this study, microarray data GSE35958 were downloaded from Gene Expression Omnibus, then the differentially expressed genes (DEGs) were identified by limma package. Gene Ontology (GO) and KEGG pathway enrichment analyses were performed for both up- and down-regulated DEGs using DAVID. In addition, the transcription factor analysis was conducted for DEGs. The protein-protein interaction (PPI) network was constructed by STRING and Cytoscape. Finally, CFinder was used to analyze the PPI sub-network. RESULTS Totally, 327 up-regulated DEGs and 396 down-regulated DEGs were identified. The DEGs such as EGFR and AKT1 were mainly enriched in the pathway of focal adhesion. EGFR was also involved in cell adhesion based on GO enrichment analysis. Functional analysis of DEGs indicated that 26 transcription factors were screened. Moreover, EGFR, AKT1 and transcription factor CTNNB1 were the key nodes with high degrees according to PPI network and sub-network. CONCLUSIONS The literature suggested that AKT1, EGFR and CTNNB1 were closely related to osteoblastic differentiation and osteoclastogenesis. Some crucial DEGs such as EGFR, AKT1 and CTNNB1 might be connected with primary osteoporosis and could be used as therapeutic targets of osteoporosis.

Abstract
Immune response plays an important role in the development of hepatic fibrosis. In
the present study, we investigated the effects of quercetin on hepatitis and hepatic
fibrosis induced by immunological mechanism. In the acute hepatitis model, quercetin
(2.5 mg/kg) was injected iv into mice 30 min after concanavalin A
(Con A) challenge. Mice were sacrificed 4 or 24 h after Con A injection, and
aminotransferase tests and histopathological sections were performed. Treatment with
quercetin significantly decreased the levels of alanine aminotransferase (ALT) and
aspartate aminotransferase (AST). Consistent with this observation, treatment with
quercetin markedly attenuated the pathologic changes in the liver. A hepatic fibrosis
model was also generated in mice by Con A challenge once a week for 6 consecutive
weeks. Mice in the experimental group were treated with daily iv
injections of quercetin (0.5 mg/kg). Histopathological analyses revealed that
treatment with quercetin markedly decreased collagen deposition, pseudolobuli
development, and hepatic stellate cells activation. We also examined the effects of
quercetin on the nuclear factor kappa-light-chain-enhancer of activated B cells
(NF-κB) and transforming growth factor beta (TGF-β) pathways by immunohistochemistry
and real-time reverse transcriptase-polymerase chain reaction (RT-PCR). NF-κB and
TGF-β production was decreased after treatment with quercetin, indicating that the
antifibrotic effect of quercetin is associated with its ability to modulate NF-κB and
TGF-β production. These results suggest that quercetin may be an effective
therapeutic strategy in the treatment of patients with liver damage and fibrosis.

Abstract
A measurement of the energy dependence of antineutrino disappearance at the Daya Bay reactor neutrino experiment is reported. Electron antineutrinos (ν¯(e)) from six 2.9 GW(th) reactors were detected with six detectors deployed in two near (effective baselines 512 and 561 m) and one far (1579 m) underground experimental halls. Using 217 days of data, 41 589 (203 809 and 92 912) antineutrino candidates were detected in the far hall (near halls). An improved measurement of the oscillation amplitude sin(2)2θ(13)=0.090(-0.009)(+0.008) and the first direct measurement of the ν¯(e) mass-squared difference |Δm(ee)2|=(2.59(-0.20)(+0.19))×10(-3) eV2 is obtained using the observed ν¯(e) rates and energy spectra in a three-neutrino framework. This value of |Δm(ee)2| is consistent with |Δm(μμ)2| measured by muon neutrino disappearance, supporting the three-flavor oscillation model.

Abstract
Hypothalamic glutamate (Glu) and γ-GABA neurotransmission are involved in the ovarian hormone-induced gonadotrophin-releasing hormone (GnRH)/luteinising hormone (LH) surge in rodents. Studies have shown that reduced Glu and increased γ-GABA in the rostral preoptic area (rPOA) of the hypothalamus, where most activated GnRH neurones are located, play a key role in decreasing the reproductive function of female rats. However, the mechanism underlying the altered balance of these neurotransmitters is poorly understood. In the present study, we observed a decline in the function of GnRH neurones in the rPOA at the time of the GnRH/LH surge in middle-aged intact female mice with regular oestrous cycles. In young mice, there is an increase of vesicular Glu transporter 2 on the pro-oestrus afternoon, which is not observed in middle-aged mice. By contrast, vesicular γ-GABA transporter levels in young mice decrease at the time of the LH surge, whereas they increase in middle-aged mice. Of note, we found that, in middle-aged mice at the time of the GnRH/LH surge, the phosphorylation of synapsin I at Ser603 and Ca(2+) /calmodulin-dependent kinase IIα was significantly lower than in young mice. These data suggest that, in middle-aged mice, higher levels of presynaptic stores of GABA, a lack of increase of Glu and a decreased ability of synaptic vesicle mobilisation could account for the imbalance of Glu and GABA in the rPOA, which decreases the activation of GnRH neurones.

Abstract
V-erb-a erythroblastic leukemia viral oncogene homolog 4 (ERBB4) has been reported to be somatically mutated in 19% of melanoma cases. To investigate the prevalence of ERBB4 mutations in melanoma patients from southern China, we analyzed 117 formalin-fixed, paraffin-embedded melanoma samples archived in the Sun Yat-sen University Cancer Center. A matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) platform was used to screen for mutations. No ERBB4 hotspot mutations were detected. Our results indicate that ERBB4 mutations may play a limited role in melanomas in China; therefore, targeting the ERBB4 mutation in melanoma patients from southern China may not be a promising strategy.

Abstract
OBJECTIVE To evaluate the effect of chronic virus infection on laboratory tests results in patients with osteoarticular tuberculosis. METHODS A total of 121 patients with osteoarticular tuberculosis, who were hospitalized in Shenzhen Third People's Hospital during June 2008 to June 2012, were recruited for analysis. Clinical laboratory tests results were collected for comparison between patients with or without chronic co-infection with virus. RESULTS Among the 121 patients, thirty patients were co-infected with hepatitis B virus (HBV), two were with Human immunodeficiency virus (HIV), and one was co-infected with HBV, HIV and hepatitis C virus (HCV). Compared to patients with osteoarticular tuberculosis without HBV/HCV/HIV infection, patients with chronic HBV/HCV/HIV virus infection had similar positive rate of laboratory tests including tissue smear acid-fast bacilli (AFB) staining, tissue Mycobacterium tuberculosis (Mtb) culture, tissue Mtb DNA detection, serological test of antibodies against Mtb, and Mtb. antigen-specific interferon-gamma release assay. Similar results were also found for erythrocyte sedimentation rate, C-reative protein level and liver function including Alanine aminotransferase and Aspartate Aminotransferase. CONCLUSION Chronic infection with HBV/HCV in patients with have no obvious effect on clinical laboratory tests related to tuberculosis.

Abstract
Isochronous mass spectrometry has been applied to neutron-deficient 58Ni projectile fragments at the HIRFL-CSR facility in Lanzhou, China. Masses of a series of short-lived T(z)=-3/2 nuclides including 41Ti, 45Cr, 49Fe, and 53Ni have been measured with a precision of 20-40 keV. The new data enable us to test for the first time the isobaric multiplet mass equation (IMME) in fp-shell nuclei. We observe that the IMME is inconsistent with the generally accepted quadratic form for the A=53, T=3/2 quartet. We perform full space shell model calculations and compare them with the new experimental results.

Abstract
The Daya Bay Reactor Neutrino Experiment has measured a nonzero value for the neutrino mixing angle θ(13) with a significance of 5.2 standard deviations. Antineutrinos from six 2.9 GWth reactors were detected in six antineutrino detectors deployed in two near (flux-weighted baseline 470 m and 576 m) and one far (1648 m) underground experimental halls. With a 43,000 ton-GWth-day live-time exposure in 55 days, 10,416 (80,376) electron-antineutrino candidates were detected at the far hall (near halls). The ratio of the observed to expected number of antineutrinos at the far hall is R=0.940±0.011(stat.)±0.004(syst.). A rate-only analysis finds sin(2)2θ(13)=0.092±0.016(stat.)±0.005(syst.) in a three-neutrino framework.

Abstract
OBJECTIVE To explore the association between HBV genotyping and clinical characteristics and expression of TH1/TH2 cytokines. METHODS The expression of IL-4 and IFN-gamma was detected with flow cytometry for 102 HBV infections and 48 healthy controls. 50 CHB patients were randomly selected for HBV genotyping with real-time fluorescence PCR assay. RESULTS Higher expression of IL-4 in peripheral blood was detected in patients with HBV infection than healthy controls (P < 0.001); No significant differences on expression of Th1/Th2 cytokines were observed in CHB patients with different HBV DNA levels or HBeAg status (P > 0.05). There were 34 (68%) patients with genotype B infection and 16 (32%) with genotype C infection. Compared to patients with genotype B infection, the patients with genotype C infection showed higher levels of IL-4 (P = 0.018), and Th1/Th2 ratio decreased,but the difference was not statistically significant (P = 0.2262). CONCLUSION The different expression of TH1/TH2 cytokines may elucidate cellular immune response and clinical outcome difference between patients with genotype B infection and genotype C infection.

Abstract
Hand–foot–mouth disease due to enterovirus 71 (EV71) and coxsackievirus A16 (CA16) has recently caused large outbreaks in mainland China in 2008. We performed complete genome sequencing on two EV71 (SZ/HK08-5 and SZ/HK08-6) and two CA16 (SZ/HK08-3 and SZ/HK08-7) strains from patients in Shenzhen, China. Phylogenetic, similarity plot and bootscan analyses revealed recombination between EV71 genotypes B and C at the 2A–2B junction, and between EV71 genotype B and CA16 strain G-10 in the 3C region for EV71 strains. A similar phenomenon was also found upon further gene sequencing with other EV71 strains. Recombination between CA16 strain G-10 and EV71 genotype A at the 2A–2B junction was also observed for CA16 strains. The present “double-recombinant” EV71 strains circulating in China and other EV71 subgenotype “C4” strains represent an additional genotype, D. CA16 strains should also be classified into two genotypes. This represents the first evidence for a combination of intratypic and intertypic recombination in EV71 strains.

Abstract
OBJECTIVE To investigate the effects of inactivation of CD(4)(+)CD(25)(+) regulatory T cells (Treg) combined with the administration of levofloxacin (LFX) on the cellular immune response of murine tuberculosis. METHODS Inactivation of Treg was achieved by intraperitoneal injection of anti-CD(25), clone PC61. Female C57BL/6 mice were divided into 4 groups, PC61 alone, LFX alone, PC61 plus LFX, and the control, with 19 mice in each group. The LFX group and the control group were treated with rat-IgG isotope control. Mice were inoculated with H(37) Rv (1 x 10(6) CFU) via the tail vein 3 days later. From the 2nd day, the LFX group and the PC61 plus LFX group received intragastric administration of LFX at 200 mg x kg(-1) x d(-1) per mouse for 45 days. Blood and spleen Tregs were measured by flow cytometry. The cellular immune response and pulmonary histopathology at different time points were also evaluated after infection. RESULTS At the 10th and 30th day, the ratio of CD(4)(+)CD(25)(+)/CD(4)(+)T cells in the spleen was (30 +/- 4)% and (17.3 +/- 1.6)% respectively in the control group, (21 +/- 4)% and (16.1 +/- 1.3)% respectively in the PC61 group, (44 +/- 6)% and (24.7 +/- 2.0)% respectively in the LFX group, (24 +/- 3)% and (10.4 +/- 1.0)% respectively in the PC61 plus LFX group. The differences were significant between groups (q = 3.62 - 5.56, P < 0.05), but the difference between the PC61 plus LFX group and the PC61 group at the 10th day. Same results were obtained from the peripheral blood. PC61 plus LFX therapy resulted in BCG specific cytokine response (IL-17, IFN-gamma, TNF-alpha) from murine spleen cells at the 10th and the 30th day, and also in milder pathologic changes and the lowest mortality. CONCLUSIONS The cellular immune response was enhanced by Treg inactivation and LFX therapy, which decreased the pathologic changes and the mortality of murine tuberculosis.

Abstract
OBJECTIVE To evaluate the expression of CD49d, CCR9, CD62L and CCR5 on CD4+ T cells in AIDS patients before and after HAART. METHODS The study was performed in 42 cases of AIDS patients and 18 cases of healthy controls. The expression of CD49d, CCR9, CD62L and CCR5 on CD4+ T cells, and CD45RO on CD4+ CCCR9+ and CD4+ CCR5+ T cells in AIDS patients and healthy controls were analysed by Flow cytometry. Software BD FACSDiva was used to calculate the percentage of expression. RESULTS The number of peripheral CD4+ T cells in group pre-HAART was decreased compared with group HAART (P < 0.01); the frequency of CD3+ CD4+, CD4+ CCR9+, CD4+ CCR5+ T cells in group pre-HAART were decreased compared with group HAART (P < 0.01), the frequency of CD4+ CD49d+, CD4+ CD62L+, CD4+ CCR9+ CD45RO , CD4+ CCR9+ CD45RO- ,CD4+ CCR5+ CD45RO+, CD4+ CCR5+ CD45RO- T cells in group pre-HAART were significantly decreased compared with group HAART (P < 0.001); the frequency of CD3+ CD4, CD4+ CD62L+, CD4+ CCR5+ T cells in group HAART were significantly decreased compared with group HIV-neg (P < 0.05). CONCLUSIONS Not only the number but the function of CD4' T cells was impaired in AIDS patients: the lower expression frequency of gut homing receptor molecule CD49d and CCR9,1ymph node homing molecule CD62L, coreceptor molecule CCR5. HAART can partially reverse this pathological phenomena. CD49d, CCR9 and CD62L may be suggested to indicate the progression of AIDS and immunologic reconstitution after HAART.

Abstract
OBJECTIVE To generate a recombinant Adenovirus encoding a GFP (green fluorescent protein)-report gene and a single-chain trimer of MHC restricted HBsAg CTL epitope. METHODS An oligonucleotide encoding H-2L(d) restricted HBsAg CTL epitope was synthesized and fused with H-2L(d) DNA molecule to construct the eukaryotic expression vector carrying the HBsAg-SCT gene. The HBsAg-SCT gene was subcloned into a GFP adenovirus expression vector,which was transfected into Ad293 cells for packaging and amplification of recombinant adenovirus encoding HBsAg-SCT. RESULTS HBsAg-SCT has been cloned into an adenovirus vector encoding GFP report gene successfully as confirmed by double enzyme digestion and direct sequencing. HBsAg-SCT was expressed by infected Ad293 cells demonstrated by western blot assay. CONCLUSION A recombinant adenovirus expressing HBsAg-SCT and green fluorescent protein report gene has been generated.

Abstract
The aim of this clinical study was to determine the optimal time-window for surgical treatment of spontaneous intracerebral hemorrhage (ICH). From January 1998 to September 2000, 17 hospitals in Shanghai participated in a prospective randomized controlled trial. Among a consecutive series of 500 patients with spontaneous ICH, 234 underwent medical treatment and 266 patients received surgical treatment. According to the interval from initial onset to treatment, they were divided into 3 stages: ultra-early (< or =7 h), early (7-24 h), and delayed (> 24 h). Perioperative evaluation (Glasgow Outcome Score), long-term outcome (the activities of daily living [ADL] score), mortality, as well as incidence of associated complications were compared respectively. We found that: a) in the ultra-early and early stages, both the perioperative and long-term outcome of surgical treatment was definitely better than medical treatment; b) for the outcome of surgical treatment, there was no significant difference between ultra-early and early stages; c) in ultra-early stage, risk of postoperative rebleeding was significantly higher, and decreased henceforth; d) in delayed stage, incidence of associated respiratory, urinary, and gastrointestinal system complications was higher in surgery group than in medication group. In summary, our study yielded conclusive evidence that the early stage (within 7-24 h) was the optimal time-window for surgical intervention of spontaneous ICH.

Abstract
OBJECTIVE To obtain the purified early secretory antigenic target-6 (ESAT-6) protein and to evaluate its application in detection of Mycobacterium tuberculosis antigen-specific interferon-gamma (IFN-gamma) response. METHODS ESAT-6 protein was expressed by genetic engineering. The antigen specificity and reactivity of ESAT-6 were evaluated by Western blot. Using ESAT-6 as the antigen, the antigen-specific IFN-gamma response in patients with tuberculosis, healthy medical workers, and village residents was detected by the Elispot method. The results were also compared with those obtained by a commercial kit (QuantiFERON-TB-GOLD, QFT-G). RESULTS ESAT-6 protein was successfully expressed and purified, and the antigen specificity of ESAT-6 was confirmed by its recognition by the antigen-specific antibody (anti-ESAT-6). The specificity and sensitivity of the Elispot assay using ESAT-6 as the antigen in detecting the IFN-gamma response was comparable with those of the commercial kit (QFT-G). The positive rates of the Elispot assay for patients with tuberculosis, healthy medical workers and villagers were 36/49 (73.5%), 11/62 (17.7%), and 17/194 (8.8%), respectively, while the rates of the OFT-G method for patients with tuberculosis and healthy medical workers were 38/49 (77.6%) and 14/58 (24.1%), respectively. The sensitivity (73.5%, 77.6%; chi2 = 0.381, P > 0.05) and specificity (82.3%, 75.9%; chi2 = 0.406, P > 0.05) of these two methods did not differ significantly. CONCLUSIONS Recombinant ESAT-6 protein was expressed and purified. Elispot using recombinant ESAT-6 protein as antigen showed high sensitivity and specificity for detection of Mycobacterium tuberculosis antigen-specific IFN-gamma response. The purified ESAT-6 can be used for diagnosis of Mycobacterium tuberculosis infection.

Abstract
Human parvovirus 4 (PARV4), a recently discovered parvovirus found exclusively in human plasma and liver tissue, was considered phylogenetically distinct from other parvoviruses. Here, we report the discovery of two novel parvoviruses closely related to PARV4, porcine hokovirus (PHoV) and bovine hokovirus (BHoV), from porcine and bovine samples in Hong Kong. Their nearly full-length sequences were also analysed. PARV4-like viruses were detected by PCR among 44.4 % (148/333) of porcine samples (including lymph nodes, liver, serum, nasopharyngeal and faecal samples), 13 % (4/32) of bovine spleen samples and 2 % (7/362) of human serum samples that were sent for human immunodeficiency virus and hepatitis C virus antibody tests. Three distinct parvoviruses were identified, including two novel parvoviruses, PHoV and BHoV, from porcine and bovine samples and PARV4 from humans, respectively. Analysis of genome sequences from seven PHoV strains, from three BHoV strains and from one PARV4 strain showed that the two animal parvoviruses were most similar to PARV4 with 61.5-63 % nt identities and, together with PARV4 (HHoV), formed a distinct cluster within the family Parvoviridae. The three parvoviruses also differed from other parvoviruses by their relatively large predicted VP1 protein and the presence of a small unique conserved putative protein. Based on these results, we propose a separate genus, Hokovirus, to describe these three parvoviruses. The co-detection of porcine reproductive and respiratory syndrome virus, the agent associated with the recent 'high fever' disease outbreaks in pigs in China, from our porcine samples warrants further investigation.

Abstract
OBJECTIVE To investigate of the relationship of the immunosuppression induced by Measles virus in adult patients and CD4+ CD25+ regulatory T cell. METHODS Thirty-four patients with measles and 27 healthy control subjects were included in this study. The whole blood was collected and CD4+ CD25+ cell and FoxP3+ cell were analyzed by flow cytometry, and CD4+ CD25- and CD4+ CD25+ T lymphocytes were isolated from PBMCs of patients with measles or healthy donors, CD4+ CD25- T cells were cultured in absence or presence of anti-CD3, or BCG, or live attenuated MV. The cell culture supernatant was collected after 72 hours and the concentration of IFN-gamma and IL-10 was determined. RESULTS Compared to healthy donors, we observed a reduction of the number of white blood cells and lymphocytes in patients with measles, but there was not significantly different in the frequency of CD4+ CD25+ T cells and CD4+ CD25high T cells within the total CD4+ population in the blood. Treg from both measles patients and healthy controls significantly inhibited IFN-gamma production by CD4+ CD25- T cells in response to anti-CD3 stimulation. CONCLUSION Induction and expansion of Treg may not represent a mechanism involved in the establishment of immune suppression by MV.

Abstract
INTRODUCTION Intracerebral hemorrhage (ICH) is one of the most common clinical manifestations of human brain arteriovenous malformation (BAVM). However, the hemorrhagic mechanism of BAVM is still unclear. Leptin, first discovered in obesity research, has not been systematically studied in BAVM and ICH. We investigated expression and effect of leptin on human BAVM. METHODS Specimens were obtained from 6 BAVM patients, who had been divided into either hemorrhagic or non-hemorrhagic groups. Leptin, leptin receptor, and signal transducers and activators of transcription-3 (STAT3) were analyzed by different methods, such as gene chips, reverse transcription-polymerase chain reaction (RT-PCR), immunohistochemistry, and Western blot. Perinidal brain tissue around each BAVM served as control. RESULTS Gene chips and RT-PCR found transcriptional leptin raised at least 2 levels in hemorrhagic BAVM. Immunohistochemical slices also showed higher expression of leptin, leptin receptor, and STAT3 on nidus part of hemorrhagic BAVM than non-hemorrhagic ones. On Western blot analysis, hemorrhagic BAVMs had higher levels of leptin (p < 0.01). CONCLUSIONS The transcriptional and translational levels of leptin, leptin receptor, and STAT3 were higher in hemorrhagic BAVM, suggesting that leptin may play an important role in the hemorrhagic mechanism of BAVM.
