Abstract
Objective: To explore the causes and therapeutic effects of pelvic pain caused by rectal fistula or bladder fistula after comprehensive treatment of cervical cancer and rectal cancer (radiotherapy, surgery, chemotherapy, and other treatments). Methods: A retrospective analysis was conducted on the clinical and pathological data of patients with pelvic tumors admitted to the First People's Hospital of Yinchuan City, Ningxia and the Affiliated Cancer Hospital of Zhengzhou University from June 2016 to June 2022. The causes of persistent pelvic pain in patients after comprehensive treatment was investigated, and the corresponding therapeutic effects after clinical treatment was observed. Results: Thirty-two tumor patients experienced persistent pain after comprehensive treatment, including 22 cases of cervical cancer and 10 cases of rectal cancer. The preoperative pain of the entire group of patients was evaluated using the digital grading method, with a pain score of (7.88±1.31) points. Among the 32 patients, there were 16 cases of rectovaginal fistula or ileovaginal fistula, 9 cases of vesicovaginal fistula, 5 cases of rectoperineal fistula, and 2 cases of vesicovaginorectal fistula. Thirty-two patients were initially treated with medication to relieve pain, and according to the ruptured organs, a fistula was made to the corresponding proximal intestinal canal and renal pelvis to intercept the intestinal contents and urine. However, the pain did not significantly be improved. The pain score of treatment with the above methods for one week was (8.13±1.13) points, and there was no statistically significant difference compared to preoperative treatment (P=0.417). In the later stage, based on a comprehensive evaluation of whether the tumor had recurred, the value of organ preservation, the benefits of surgery, the balance between survival time and improving quality of life, pathological organ resection or repair was performed. The surgical methods included repair of leaks, local debridement combined with irrigation of proximal intestinal fluid, distal closure of the sigmoid colon combined with proximal ostomy, posterior pelvic organ resection, anterior pelvic organ resection, and total pelvic organ resection. One week after surgery, the patients' pain completely relieved or disappeared, with the pain score of (1.72±1.37) points, which was significantly divergent from the preoperative and initial surgical treatments (P<0.001). Conclusions: Palliative pyelostomy and proximal enterostomy cannot effectively alleviate persistent pelvic floor pain. The fundamental way to alleviate pain is complete blocking of the inflammatory erosion of the intestinal fluid and urine.

Abstract
OBJECTIVES Anti-MDA5+ dermatomyositis was associated with poor prognosis due to the high incidence of rapid progressive interstitial lung disease, pulmonary infection. The aim of this study is to investigate the abundance and clinical relevance of exhaustion markers on peripheral CD8 T cells from patients with idiopathic inflammatory myopathy (IIM). METHODS Twenty-nine healthy controls (HCs) and 71 patients with IIM were enrolled, including 42 with anti-MDA5+ and 18 with anti-MDA5- dermatomyositis (DM) and 11 with anti-synthetase syndrome (ASS). Flow cytometry was applied to detect PD-1, TIM-3 and LAG-3 in CD8 T cells. The clinical associations of the CD8 T cell exhaustion phenotype in patients with anti-MDA5+ DM were analysed. RESULTS CD8 T cells from patients with anti-MDA5+ DM showed significantly increased LAG-3, TIM-3 and PD-1 compared to those from patients with anti-MDA5- IIM (18 with anti-MDA5- DM and 11 with ASS) or HCs (adjusted p all < 0.05). CD8 T cells with distinct exhaustion levels were all significantly increased in anti-MDA5+ DM patients compared with HCs (p all < 0.05). Patients with high level of PD-1+ TIM-3+LAG-3+ CD8+ T cells had a significant higher incidence of pulmonary fungal infections but lower counts of CD4+ and CD8+ T cells. ROC analysis revealed that the frequency of PD-1+TIM-3+LAG-3+CD8+ T cell significantly predicted pulmonary fungal infections (area under the curve: 0.828). CONCLUSIONS CD8 T cells from patients with anti-MDA5+ DM show significant exhausted phenotype, and increased exhausted CD8 T cells were associated with high risk of pulmonary fungal infection.

Abstract
Objective: To investigate the causes and management of long-term persistent pelvic presacral space infection. Methods: Clinical data of 10 patients with persistent presacral infection admitted to the Cancer Hospital of Zhengzhou University from October 2015 to October 2020 were collected. Different surgical approaches were used to treat the presacral infection according to the patients' initial surgical procedures. Results: Among the 10 patients, there were 2 cases of presacral recurrent infection due to rectal leak after radiotherapy for cervical cancer, 3 cases of presacral recurrent infection due to rectal leak after radiotherapy for rectal cancer Dixons, and 5 cases of presacral recurrent infection of sinus tract after adjuvant radiotherapy for rectal cancer Miles. Of the 5 patients with leaky bowel, 4 had complete resection of the ruptured nonfunctional bowel and complete debridement of the presacral infection using an anterior transverse sacral incision with a large tipped omentum filling the presacral space; 1 had continuous drainage of the anal canal and complete debridement of the presacral infection using an anterior transverse sacral incision. 5 post-Miles patients all had debridement of the presacral infection using an anterior transverse sacral incision combined with an abdominal incision. The nine patients with healed presacral infection recovered from surgery in 26 to 210 days, with a median time of 55 days. Conclusions: Anterior sacral infections in patients with leaky gut are caused by residual bowel secretion of intestinal fluid into the anterior sacral space, and in post-Miles patients by residual anterior sacral foreign bodies. An anterior sacral caudal transverse arc incision combined with an abdominal incision is an effective surgical approach for complete debridement of anterior sacral recalcitrant infections.

Abstract
OBJECTIVE To investigate the association between the anti-melanoma differentiation associated gene 5 (MDA5) IgG subclasses and prognosis of patients with dermatomyositis (DM)-associated interstitial lung disease (ILD). METHODS This retrospective study included 122 anti-MDA5 positive DM-ILD patients admitted from October 2017 to October 2020 as training cohort, and additional 68 patients from August 2014 to September 2017 as validation cohort. The levels of anti-MDA5 total IgG and IgG subclasses were measured using in-house enzyme-linked immunosorbent assays, and analysed in association with the patient prognosis. RESULTS In the training cohort, the concentrations of anti-MDA5 IgG1 and IgG3 in non-survivors were significantly higher than in survivors (P < 0.05), whereas there were no significant differences in the IgG2 and IgG4 levels. Kaplan-Meier survival analysis revealed that the levels of anti-MDA5 total IgG, IgG1 and IgG3 were associated with mortality (P < 0.05). Multivariate analysis revealed anti-MDA5 IgG1 >13 U/ml and anti-MDA5 IgG3 >11 U/ml were independent risk factors for death of DM-ILD patients (P < 0.05). Anti-MDA5 IgG1 was confirmed as an independent risk factor in the validation cohort, while anti-MDA5 IgG3 was not. Anti-MDA5 IgG1 showed greater discriminable power for patient prognosis (Youden index 0.494) than anti-MDA5 total IgG, IgG3, or the combination of IgG1 and IgG3 (Youden index 0.356, 0.32 and 0.447, respectively). CONCLUSION Anti-MDA5 IgG1 and IgG3 are significantly associated with poor prognosis in DM-ILD patients, and anti-MDA5 IgG1 is more efficient as a prognostic biomarker in DM-ILD patients.

Abstract
Myositis-associated interstitial lung disease (M-ILD) is a heterogeneous group of diseases. It can be divided into different subtypes listed below according to different myositis antibodies. (1) ASS-related ILD responds well to glucocorticoid plus immunosuppressant therapy but tends to relapse. (2) Anti-MDA5-related ILD is the worst prognosis of M-ILD with high mortality rate, and most patients die within the first 6 months of the disease course. (3) Non-MDA-5 DM-associated ILD is often mild, and NSIP is the main HRCT pattern. (4) IMNM-associated ILD shows mild clinical symptoms of ILD in majority of the case, and NSIP is also the main HRCT pattern. (5) With MAA-associated ILD, anti-Ku-positive patients are more common complicated with ILD. In addition, the changes of serum levels of myositis antibody are generally positively correlated with disease activity, and titer drop after disease remission. Therefore, myositis antibodies are important immunological biomarkers for clinical typing and prognosis of M-ILD.

Abstract
Objective: The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China. Methods: This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems. Results: According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%). Conclusion: Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

Abstract
Objective: To investigate the reoperation and perioperative management of residual cyst wall with perineal intractable sinus after resection of presacral cyst tumors. Methods: The clinical data of 29 patients with residual cyst wall and perineal intractable sinus after resection of presacral cyst tumors in Affiliated Cancer Hospital of Zhengzhou University from January 2014 to August 2019 were reviewed, including the characteristics of the residual cyst wall with perineal intractable sinus after resection of presacral cyst tumors, surgical method, and perioperative management. Results: Twenty-nine patients with residual cyst wall and perineal intractable sinus after resection of presacral cyst tumors, including 9 cases of epidermoid cysts, 7 cases of dermoid cysts, 10 cases of mature teratomas and 3 cases of malignant cysts (including malignant transformation of caudate cyst and teratoma); The 29 patients underwent posterior approaches for cyst resection in other hospital before, of whom 1 patient underwent posterior combined with transabdominal approach. All of thes patients underwent resection of residual presacral cyst wall and perineal intractable sinus in our hospital, of whom 25 patients underwent a transperineal approach through an arc-shaped incision anterior to the apex of the coccyx, and the other 4 patients underwent transperineal arc-shaped incision combined with transabdominal approach. All of the patients were cured without serious complications occurring, postoperative pathological and the magnetic resonance imaging diagnosis showed that the residual cyst wall and perineal intractable sinus were all completely removed. Conclusion: Appropriate surgical approache and perioperative treatment for the patients with residual cyst wall and perineal intractable sinus are very important to promote the resection of residual cyst wall and the healing of perineal intractable sinus.

Abstract
Background Dermatomyositis (DM) associated rapidly progressive interstitial lung disease (RP-ILD) has high mortality rate and poor prognosis. Galectin-9 (Gal-9) plays multiple functions in immune regulation. We investigated Gal-9 expression in DM patients and its association with DM-ILD. Methods A total of 154 idiopathic inflammatory myopathy patients and 30 healthy controls were enrolled in the study. Cross-sectional and longitudinal studies were used to analyze the association between serum Gal-9 levels and clinical features. Enzyme-linked immunosorbent assay and qRT-PCR were used to examine Gal-9 expression in the sera and isolated peripheral blood mononuclear cells (PBMCs) from DM patients. Immunohistochemistry was performed to analyze the expression of Gal-9 and its ligand (T-cell immunoglobulin mucin (Tim)-3 and CD44) in lung tissues from anti-melanoma differentiation-associated gene 5 (MDA5)-positive patients. The effect of Gal-9 on human lung fibroblasts (MRC-5) was investigated in vitro. Results Serum Gal-9 levels were significantly higher in DM patients than in immune-mediated necrotizing myopathy patients and healthy controls (all p < 0.001). Higher serum Gal-9 levels were observed in anti-MDA5-positive DM patients than in anti-MDA5-negative DM patients [33.8 (21.9–44.7) vs. 16.2 (10.0–26.9) ng/mL, p < 0.001]. Among the anti-MDA5-positive DM patients, serum Gal-9 levels were associated with RP-ILD severity. Serum Gal-9 levels were significantly correlated with disease activity in anti-MDA5-positive DM patients in both cross-sectional and longitudinal studies. PBMCs isolated from anti-MDA5-positive DM patients (3.7 ± 2.3 ng/mL) produced higher levels of Gal-9 than those from immune-mediated necrotizing myopathy patients (1.1 ± 0.3 ng/mL, p = 0.022) and healthy controls (1.4 ± 1.2 ng/mL, p = 0.045). The mRNA levels of Gal-9 were positively correlated with the levels of type-I interferon-inducible genes MX1 (r = 0.659, p = 0.020) and IFIH1 (r = 0.787, p = 0.002) in PBMCs from anti-MDA5-positive DM patients. Immunohistochemistry revealed increased Gal-9 and Tim-3 expression in the lung tissues of patients with DM and RP-ILD. In vitro stimulation with Gal-9 protein increased CCL2 mRNA expression in MRC-5 fibroblasts. Conclusions Among anti-MDA5-positive DM patients, Gal-9 could be a promising biomarker for monitoring disease activity, particularly for RP-ILD severity. Aberrant expression of the Gal-9/Tim-3 axis may be involved in the immunopathogenesis of DM-ILD.

Abstract
Objectives: To delineate clinico-pathological features, treatment and outcome of skeletal muscle single-organ vasculitis (SM-SOV). Methods: The clinico-pathological characteristic of SM-SOV cases treated over 3 years in China-Japan Friendship Hospital were retrospectively analyzed and the data were compared with the cases from the literature. Results: Five patients (2 women and 3 men) with a median age of 36 years were included in this study. The main clinical manifestations were lower limb myalgia (5/5) and fever (1/5). The most frequent laboratory findings included high erythrocyte sedimentation rate (5/5), high C reactive protein (5/5) and leukocytosis (1/5). No elevated creatine kinase (CK) was found in these cases. Four patients received electromyogram examination and none of them showed myogenic injury. On MRI, hyperintense signals in T2 weighted image (T2WI) and/or short TI inversion recovery (STIR) and normal unenhanced T1 weighted image (T1WI) of one or several leg muscles was founded in all 5 patients. All muscle specimens showed nongranulomatous vasculitis without myonecrosis affecting small sized artery (5/5) in perimysia (75.0%, 3/4) or both perimysia and fascia (25.0%, 1/4). Corticosteroids (5/5) and immunosuppressants (5/5) were the main agents prescribed. With a median follow-up of 24 months, sustained remission was observed in 3 patients, relapses occurred in 2 patients. Conclusion: SM-SOV should be considered for patients with lower limb myalgia, high inflammatory markers and normal/low CK level. The diagnosis of SM-SOV should be applied when there are both histologic evidence of vasculitis and a minimum of 6 months of follow-up surveillance without evidences suggesting extra-muscular involvement. Corticosteroid combined with immunosuppressant is effective.

Abstract
INTRODUCTION Baricitinib is an oral, selective inhibitor of Janus kinase which demonstrates clinical efficacy in patients with rheumatoid arthritis (RA). This report aims to analyze the onset time of baricitinib in Chinese patients with moderately to severely active RA who had an inadequate response to methotrexate. METHODS This post hoc analysis evaluated clinical improvements of Chinese patients treated with baricitinib 4 mg once daily compared with placebo, based on data from a phase 3 study RA-BALANCE. Efficacy measures including American College of Rheumatology 20% (ACR20) response, ACR core set values, Disease Activity Score modified to include the 28 diarthrodial joint count (DAS28) using high-sensitivity C-reactive protein (hsCRP), DAS28-erythrocyte sedimentation rate, Simplified Disease Activity Index, Clinical Disease Activity Index, DAS28-hsCRP ≤ 3.2 response (low disease activity), and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) were evaluated at weeks 1, 2, 4, 8, 12, 14, 16, 20, and 24 (except for FACIT-F evaluated every 4 weeks). A logistic regression model and an analysis of covariance model were used to analyze treatment comparisons of categorical and continuous measures, respectively. RESULTS Statistically significant (p ≤ 0.05) improvements were observed as early as week 1 or 2 for the baricitinib group compared to placebo in almost all main efficacy measures. For other outcomes including 66 swollen joint count, 68 tender joint count, FACIT-F, and DAS28-hsCRP ≤ 3.2 response rate, differences were evident (p ≤ 0.05) by week 4 in the baricitinib group compared with placebo. Significant improvements in all efficacy measures were sustained through 24 weeks. CONCLUSIONS Baricitinib demonstrated a rapid onset of efficacy on ACR20 response, ACR core set values, disease activity, and patient-reported outcome improvements in Chinese patients from RA-BALANCE.

Abstract
Objective: To investigate the types and treatment methods of easily-missed, misdiagnosed intestinal obstruction after radical radiotherapy of cervical cancer. Methods: The clinical data of 21 patients with intestinal obstruction after radical radiotherapy of cervical cancer in our hospital from May 2013 to May 2019 were collected, including the radiation dose, obstruction symptoms, surgical methods and treatment outcomes. The types and treatment methods of intestinal obstruction after radical radiotherapy of cervical cancer were further investigated. Results: The intestinal obstruction occurred in 21 patients with cervical cancer after radical radiotherapy. All patients were initially diagnosed as rectal obstruction and underwent the transverse colostomy. The obstruction symptoms were successfully resolved in 15 patients while failed in other 6 patients who then underwent the re-operation. Four patients with rectal obstruction accompanied by middle or terminal ileum obstruction underwent ileostomy, the other 2 patients with terminal ileum obstruction underwent the transverse ileal anastomosis and partial intestines exclusion surgery. All of the obstruction symptoms were alleviated. Conclusions: Rectal is the major obstruction site of the cervical cancer patients with intestinal obstruction after radical radiotherapy. However, a possibility of obstruction at the middle or end of the ileum also exists. Therefore, it is very important to avoid misdiagnosis and conduct appropriate operative treatment according to the obstruction site.

Abstract
OBJECTIVES Myositis autoantibodies show great utility in the diagnosis and clinico-serological phenotyping of idiopathic inflammatory myopathy (IIM). We identified a novel autoantibody against heat shock factor 1 (HSF1) and further evaluated its disease specificity and clinical significance in IIM patients. METHODS A human protein microarray was used to identify autoantibodies in myositis sera. ELISA, immunoblot and dot blot assays were applied to examine anti-HSF1 autoantibodies in IIM patients and controls. Immunofluorescence was used to detect HSF1 expression in muscle tissues. RESULTS Anti-HSF1 was identified as a novel autoantibody by protein microarray and the seroreactivity was confirmed by immunoprecipitation, ELISA, immunoblot and dot blot assays. Anti-HSF1 autoantibodies were present in 64/581 (11.0%) IIM, 4/37 (10.8%) rheumatoid arthritis, 5/40 (12.5%) primary Sjögren's syndrome, 2/40 (5%) systemic lupus erythematosus, while largely negative in healthy controls. Anti-HSF1 autoantibodies were significantly associated with pruritus, hypergammaglobulinaemia, and elevated erythrocyte sedimentation rate in IIM patients. Anti-HSF1 autoantibodies were more prevalent in cancer-associated myositis (CAM) compared to non-CAM patients (17.2% vs. 7.5%, p=0.009), nevertheless were undetectable in cancer controls. Meanwhile, cross-sectional and longitudinal analyses revealed positive correlations between anti-HSF1 levels and disease activity in IIM patients without cancer. Additionally, increased expression of HSF1 was found in regenerating muscle cells of myositis muscle tissues. CONCLUSIONS These data reveal anti-HSF1 as a new autoantibody associated with CAM in IIM. The autoimmunity against HSF1 may be involved in the immunopathogenesis of myositis.

Abstract
Objectives To investigate the prevalence and clinical significance of anti‐calreticulin autoantibodies (anti‐CRT Ab) in a large cohort of idiopathic inflammatory myopathy (IIM) patients. Methods Sera from 469 patients with IIM, 196 patients with other connective tissue diseases, 28 patients with solid tumors and 81 healthy controls were screened for anti‐CRT Ab by enzyme‐linked immunosorbent assay using human recombinant CRT protein. Sera from 35 IIM patients were tested using an immunoprecipitation assay to confirm the presence of anti‐CRT Ab. Subsequently, IIM–cancer patients were identified and divided into new‐onset, remission and recurrent groups based on their cancer status. The relationships between anti‐CRT Ab levels and IIM disease activity were also investigated. Results Serum anti‐CRT Ab was detected positive in 81 of the 469 (17.3%) IIM patients. Immunoprecipitated bands were observed at a molecular weight of 60 kDa corresponding to the CRT protein. The IIM patients with anti‐CRT Ab more frequently had cancers compared to the patients without anti‐CRT Ab. Moreover, the prevalence of anti‐CRT Ab differed according to the cancer status. The IIM patients with recurrent cancers had a much higher prevalence of anti‐CRT Ab than those with cancers in remission. Also, serum anti‐CRT Ab levels positively correlated with disease activity at baseline and at follow‐up visits. Conclusion We report the existence of serum anti‐CRT Ab in IIM patients and demonstrate the possible association of anti‐CRT Ab with malignancy in IIM patients. Serum anti‐CRT Ab could serve as a novel candidate marker of cancer in IIM patients.

Abstract
INTRODUCTION Baricitinib is an oral selective inhibitor of Janus kinase (JAK) 1 and JAK 2, which has demonstrated significant efficacy in patients with moderately to severely active rheumatoid arthritis (RA). This analysis aims to describe the efficacy and safety of baricitinib in Chinese RA patients with an inadequate response to methotrexate (MTX-IR), and to analyze the effects of baseline characteristics on the efficacy of baricitinib treatment. METHODS In this 52-week, randomized, double-blind, placebo-controlled study, 231 Chinese patients with moderately to severely active RA who had MTX-IR were randomly assigned to placebo (n = 115) or baricitinib 4 mg once daily (n = 116). The primary endpoint was American College of Rheumatology 20% (ACR20) response at week 12. Other efficacy measures included ACR50, ACR70, Physician's Global Assessment of Disease Activity, Patient's Global Assessment of Disease Activity, patient's assessment of pain, Disease Activity Score in 28 joints using high-sensitivity C-reactive protein, remission and low disease activity rates according to Simplified Disease Activity Index or Clinical Disease Activity Index, Health Assessment Questionnaire-Disability Index, and mean duration and severity of morning joint stiffness, worst tiredness and worst joint pain were analyzed. Additionally, subgroup analyses were performed across baseline characteristics. RESULTS Statistically significant improvement in ACR20 response was achieved with baricitinib at week 12 (53.4 vs. 22.6%, p = 0.001) in Chinese patients, compared to placebo. Most of the secondary objectives were met with statistically significant improvements. Efficacy of baricitinib was irrespective of patient demographics and baseline characteristics. Safety events were similar between the baricitinib and placebo groups. CONCLUSIONS The efficacy of baricitinib 4 mg in Chinese patients with moderately to severely active RA and prior MTX-IR was clinically significant compared to placebo regardless of baseline characteristics. Baricitinib was well tolerated with an acceptable safety profile during the full study period. TRIAL REGISTRATION NCT02265705.

Abstract
Objective: To explore the surgical method and effect of en bloc pelvic resection and anal preservation after radical radiotherapy for cervical cancer. Methods: Clinical data of 20 cervical cancer patients with central recurrence after radical radiotherapy underwent en bloc pelvic resection in the Tumor Hospital of Zhengzhou University and Hainan Provincial People's Hospital from January 2013 to December 2017 were retrospectively analyzed. The operative time, intraoperative blood loss, length of stay, postoperative anal function and postoperative complications were evaluated. Results: The median operation time of 20 patients with anal preservation after en bloc pelvic resection was 135.2 min, the median intraoperative blood loss was 680 ml, and the median hospitalization time was 16.5 days. Among them, 18 patients had good postoperative healing, and the anal function gradually returned to normal within 6 months after surgery, defecated 1~2 times per day.One patient showed incomplete adhesion between the external colon and the anus. One patient presented with pre-sacral infection. Postoperative pathology confirmed the recurrences in 20 patients, of which 11 cases were squamous cell carcinoma, 7 cases were adenocarcinoma, 2 cases were adenosquamous cell carcinoma. Conclusions: It is safe and reliable to preserve anus after en bloc pelvic resection for cervical cancer patients with radical radiotherapy. The anus function is good enough to improve the postoperative life quality of patients significantly.

Abstract
BACKGROUND Anti-Mi-2 antibody is a type of myositis-specific autoantibody found in idiopathic inflammatory myopathy patients. OBJECTIVES To investigate the clinical features and long-term outcomes in anti-Mi-2-positive dermatomyositis (DM) patients. MATERIALS AND METHODS Serum anti-Mi-2β antibodies were detected in 357 DM patients by enzyme-linked immunosorbent assays, and possible associated clinical features were investigated based on cross-sectional and longitudinal studies. RESULTS Of the DM patients, 40/357 (11.2%) were positive for anti-Mi-2β antibodies and found to have a significantly higher frequency of V sign (72.5% vs 45.7%; p = 0.001), shawl sign (60.0% vs 35.6%; p = 0.003), and muscle weakness (77.5% vs 57.1%; p = 0.013), but a lower incidence of interstitial lung disease (ILD) (37.5% vs 60.9%; p = 0.005) and malignancy (0% vs 12.0%; p = 0.041) than anti-Mi-2β-negative patients. Anti-Mi-2β antibody levels positively correlated with disease activity. After a median follow-up period of 44 months, 97.0% of patients showed clinical remission. Twenty-six anti-Mi-2β-positive patients had a disease course longer than two years, and 16/26 (61.5%) were monocyclic without relapse. Moreover, five patients (15.1%) were drug-free with complete remission for more than three months. Kaplan-Meier survival curves showed that DM patients with positive anti-Mi-2β had a significantly lower mortality rate compared to anti-Mi-2β-negative patients (log-rank; p = 0.035). Interestingly, anti-Mi-2β antibodies did not disappear in all patients over time. CONCLUSION Anti-Mi-2β antibodies were associated with a subgroup of DM with a low frequency of ILD and malignancy, good treatment response, and favourable outcome. Moreover, anti-Mi-2β levels correlated with disease activity.

Abstract
Objective: To assess the clinical value of neutrophil-to-lymphocyte ratio (NLR) in predicting anastomotic leak of postoperative rectal cancer patients. Methods: The clinical data of 787 rectal cancer patients who underwent anterior resection from January 2014 to December 2017 in Affiliated Tumor Hospital of Zhengzhou University were collected. The postoperative numbers of white blood cell (WBS) on postoperative day (POD)1, 3 and 5 were detected, and the NLR was calculated. The relationship of NLR and the incidence of anastomotic leak was analyzed, and the area under the receiver-operating characteristic (ROC) curves was calculated. The accuracy of postoperative NLR in predicting the incidence of anastomotic leak was evaluated. Results: WBC counts of patients with leak on POD1, POD3 and POD5 were 13.2×10(9)/L, 9.1×10(9)/L and 8.9×10(9)/L, respectively, while those of patients without leak were 12.9×10(9)/L, 9.0×10(9)/L and 8.8×10(9)/L. The WBC count was not significantly different between patients with or without leak (P>0.05). The average NLR values of patients with or without leak were 13.3 and 11.6 on POD1, 10.9 and 7.6 on POD3, 9.3 and 5.3 on POD5, respectively. The NLR values of patients with leak on POD3 and POD5 were significantly higher than those of patients without leak (P<0.05). The cutoff value of NLR on POD3 was 8.6, the sensitivity and specificity of detecting the leakage was 73.2% and 75.6%, respectively, and the area under curve (AUC) was 0.744. The cutoff value of NLR on POD5 was 5.5, the sensitivity and specificity was 69.6% and 75.5%, the AUC was 0.726. The multivariate analysis result showed that NLR >8.6 was an independent factor for anastomotic leak prediction. Conclusion: Postoperative NLR on day 3 is useful in predicting anastomotic leak and can decrease the incidence of complication in rectal cancer patients who underwent anterior resection.

Abstract
A high intensity highly charged laser ion source has been studied at the Institute of Modern Physics for the last few years. In order to investigate the processes of plasma heating and expansion of laser produced plasma, the charge state and energy distributions of the ions from pure copper, silver, and copper-silver alloy, in which the atom number ratio between copper and silver is 2:3, were measured with a 90° cylindrical electrostatic ion analyzer. It was shown that the yields of highly charged copper ions from the pure copper target are higher compared with those of the alloy target. In contrast, higher yields of highly charged silver ions were obtained from the copper-silver alloy target. Moreover, the ion energy distributions were derived from the time-of-flight spectra for the ions with different ion charge states and compared between the pure metal and alloy targets.

Abstract
A Laser Ion Source (LIS) can produce high charge state and high intensity ion beams (∼emA), especially, refractory metallic ion beams, which makes it a promising candidate as an ion source for heavy ion cancer therapy facilities and future accelerator complexes, where pulsed high intensity and high charged heavy ion beams are required. However, it is difficult for the LIS to obtain a long pulse width while ensuring high current intensity, thus limiting the application of the LIS. To solve the conflict, magnetic fields are proposed to confine the expansion of the laser produced plasma. With a solenoid along the normal direction to the target surface, the lateral adiabatic expansion of the laser ablation plasma is suppressed which extends the pulse width of the ion beam effectively. The characteristics of laser ablation plasma with solenoid field confinement will be presented and discussed in this paper.

Abstract
Objective: Serum anti Müllerian hormone (AMH) was used to evaluate the effect of cyclophosphamide (CTX) on ovarian function in female patients with systemic lupus erythematosus (SLE). Methods: A total of 121 female patients who were 18-50 years old with normal menstruation were selected. Among them, 54 patients were treated with CTX as the study group and the remaining 67 cases as the control group. Before and after treatment for 6 months, the clinical characteristics, menstruation and AMH level of all patients were recorded and detected. At the same time, the method of using CTX and the cumulative measurement are recorded. Results: (1) Before treatment, there was no significant difference in AMH and mean age, duration of disease and SLEDAI score between the CTX treatment group and the control group. The renal injury in the CTX treatment group (44.4%) was higher than that of the control group (34.3%), and the difference was statistically significant (P<0.05). (2) After 6 months of treatment, the AMH of group CTX decreased from (2.39±1.58) μg/L to (1.56±1.42) μg/L, and the difference was statistically significant (P<0.01). But there was no significant change in the control group. In 54 cases of CTX treatment group, 23 cases (42.6%) had different degree of menstrual abnormalities, while 67 cases had only 8 cases (11.9%) in the control group. Moreover, the AMH level of 31 cases with abnormal menstruation was (0.95±0.59) μg/L, which was significantly lower than that of the other 90 normal cases (2.36±1.58) μg/L. (3) In 54 cases of CTX treatment group, the cumulative dose of CTX was less than 3 g in 14 cases, 33 cases of 3-6 g, 7 cases greater than 6 g. AMH was all were lower than those before treatment. But there was a statistical difference between the 3 g group and 3-6 g group before treatment, and there were statistical differences between the groups. Conclusion: CTX can damage ovarian function in women of childbearing age SLE. Low dose intravenous CTX may have less damage. Serum AMH can be used to monitor ovarian function in patients with SLE and to guide individualized treatment.

Abstract
OBJECTIVE To study the effects of disintegrin and metalloproteinase (ADAM) 9, 15 and 17 on the osteogenic differentiation of bone marrow mesenchymal stem cells (BMMSCs). METHODS BMMSCs of ADAM9, ADAM15, ADAM17 conditional knockout mice and wild type mice (WT) were induced and cultured. Alkaline phosphatase (ALP) activity was measured by colorimetry, early osteogenic transcription factors Runx and Osterix were detected by Real-time PCR, and mineral formation was analyzed by alizarin red staining. RESULTS ALP activity was lower in ADAM9 group (8.08±0.34), ADAM15 group (6.46±3.40), ADAM17 group (9.30±2.30) than that in WT group (9.44±2.50), but there was no significant difference (P>0.05). Stimulated with bone morphogenetic protein 2(BMP2),there was significant difference (P<0.05) between ADAM9 group (14.22±3.25), ADAM15 group (10.14±2.40) and WT group (20.89±3.40), and ADAM 17 group (23.56±2.50) was higher than WT group (20.89±3.40), but no significant difference (P>0.05). Similarly, cultured by osteogenic induction medium (OST), compared with WT group (12.97±1.30), ADAM9 group (9.63±1.00) and ADAM15 group (7.75±1.30) were lower, ADAM17 group (20.09±1.68) was higher, and the difference was statistically significant (P<0.05). Using stimulated culture by BMP2 and OST combined, ADAM9 group (15.75±1.30), ADAM 15 group (12.43±1.30) were less than WT group (26.15 ±1.50), while ADAM17 group (29.55±2.10) was higher than WT group were statistically significant (P<0.05). The expression of Runx2 in ADAM9 group (2.02±0.24), ADAM15 group (3.09±0.19), ADAM17 group (3.89±0.91) had no significant difference compared with WT (2.02±0.21) group (P>0.05). ADAM9 group stimulated by BMP2 (7.00±0.23), ADAM15 group (6.04±0.23) were lower than WT group (12.6±0.23), ADAM17 group (18.52±1.39) was higher than WT group (12.6±0.23), and the difference was statistically significant (P<0.05). In non-stimulating culture, there was no significant difference in Osterix expression between ADAM9 group (9.60±3.87), ADAM17 group (12.40±3.00) and WT group (10.9±1.10, P>0.05), but in ADAM15 group (6.50±1.51) it was slightly lower than that in WT group (P<0.05). After BMP2 stimulation, ADAM9 group (39.20±3.23) and ADAM15 group (20.50±4.80) were less than WT group (60.30±5.93), while ADAM17 group (80.20±3.30) was higher than WT group (P<0.05). Alizarin red staining showed no obvious orange-red mass in the non-induction group. Local calcified nodules could be seen in the BMP2, OST, OST + BMP2 induction culture conditions in all the experimental groups, but there was no significant difference in quantitative analysis (P>0.05). CONCLUSION ADAM9, 15, 17 took part in the osteogenic differentiation of BMMSCs, and provided new targets for its regulation.

Abstract
OBJECTIVES Previous association studies have identified genetic variants in the human leukocyte antigen (HLA) complex as substantial risk factors for idiopathic inflammatory myopathies (IIMs). However, a great number of genes are located in the HLA region, and thus fine mapping is quite necessary. METHODS Targeted capture sequencing were performed on the whole HLA region in 42 IIM patients and 24 healthy controls. A microarray analysis was applied to analyze gene expression profiles in additional 20 newly diagnosed IIM and five healthy controls. RESULTS The HLA region was confirmed to be associated with IIMs in Chinese patients. By gene expression profiling and pathway analysis, several genes were identified as candidates for IIM risk factors, including HLA-A, HLA-B, HLA-DRB5, HLA-DRB1, HLA-DQA1, HLA-DQB1 and HLA-DQB2. Interestingly, p.Y107V of the HLA-DRB1 was predicted to be a potential causal non-synonymous variation for IIMs that may affect the antigen-binding groove of the HLA-II molecule. CONCLUSIONS Our data have revealed novel genetic variations in the HLA region of IIM patients and provide new insight into the pathogenesis and diagnosis of IIMs.

Abstract
Objective: To explore the surgical results and clinicopathological features of gastric cancer patients with liver metastases. Methods: The clinicopathological data and post-operative survival of 37 patients who underwent resection of liver metastasis from gastric cancer at our department from Dec. 2007 to Dec. 2014 were analyzed. Results: The 1-, 3-, and 5-year overall survival rates after resection were 91.4%, 57.9%, and 22.0%, respectively, with a median survival of 37 months. Univariate analysis revealed that lymph node metastasis, multiple hepatic metastases and no preoperative chemotherapy are unfavorable prognostic factors for overall survival. Multivariate analysis identified that lymph node metastasis and number of liver metastasis are independent prognostic factors. Conclusions: Gastric cancer patients with a solitary liver metastasis may be good candidates for gastric D2 resection combined with liver R0 resection.

Abstract
To investigate the clinical pattern, survival rate, causes of death and risk factors in a large cohort of Chinese Han patients with systemic sclerosis (SSc). Inpatients treated from 2002 to 2014 were included in this study. Patients were classified into diffuse cutaneous SSc (dcSSc), limited cutaneous SSc (lcSSc), and SSc-overlap syndrome groups. Data were analyzed using Chi-squared tests, Kaplan-Meier curves, log-rank tests, and Cox proportional hazards modeling. Among a total of 201 patients, dcSSc (50.2%) was the major subtype, followed by lcSSc (30.3%) and SSc-overlap (19.4%). Interstitial lung disease (ILD, 148/201, 74%) was the most frequent organ involvement. The overall survival rates were 98% and 95% at 5 and 10 years, respectively. The overall standard mortality ratio (SMR) was 2.22. The most common cause of death was ILD combined with infection (8/16, 50%), followed by kidney failure (2/16, 12.5%). On crude analysis, pulmonary hypertension, ILD, cardiac involvements, renal involvements, and digital ischemia were associated with poor prognosis. On multivariate analysis, pericardial effusion (p = 0.000) and digital ischemia (p = 0.016) were independent prognostic factors of death. The mortality rate of patients with SSc is mildly increased in comparison with the general population. ILD is the most common systemic involvement and the principal cause of death in SSc. Pericardial effusion and digital ischemia are independent factors associated with death.

Abstract
OBJECTIVE Low-density granulocytes (LDGs) can form neutrophil extracellular traps (NETs) spontaneously and excessively. When peripheral blood mononuclear cells (PBMCs) are used for studying T lymphocytes, LDGs contained in the PBMCs may decrease the threshold of activating T lymphocytes by forming NETs. This study focused on the profiles of LDGs in common autoimmune diseases and methods for removing LDGs from PBMCs. METHODS The percentages of LDGs in PBMCs from 55 patients with dermatomyositis (DM), 15 with polymyositis (PM), 42 with rheumatoid arthritis (RA), 25 with systemic lupus erythematosus (SLE), and 19 healthy controls were determined by flow cytometry. Three methods of removing LDGs were explored and compared. After removal, PBMCs from six patients with positive T-SPOT.TB were tested again to find out if LDGs contained in the PBMCs could influence T lymphocyte reactions. RESULTS Significantly higher LDG percentages were found in PBMCs from patients with DM ((8.41±10.87)%, P<0.0001), PM ((8.41±10.39)%, P<0.0001), RA ((4.05±6.97)%, P=0.0249), and SLE ((7.53±11.52)%, P=0.0006), compared with the controls ((1.28±0.73)%). The T-SPOT.TB values significantly decreased after LDGs were removed. Increasing relative centrifugal force (RCF) within a limited range can decrease the LDG percentage from an initial high level, but not markedly increase the LDG clearance rate. Compared with the whole blood sediment method, the PBMC adherence method can significantly remove LDGs yet scarcely influence the T lymphocyte percentage in PBMCs. CONCLUSIONS The LDG percentage in PBMCs is significantly increased in patients with SLE, DM, PM, and RA. The influence of LDGs on T lymphocytes cannot be ignored in PBMC cultures. The adherence method is a simple and easy-to-use method for removing LDGs and purifying T lymphocytes from PBMCs.

Abstract
The Toffoli gate (controlled-controlled-NOT gate) is one typical three-qubit gate, it plus a Hadamard gate form a universal set of gates in quantum computation. We present an efficient method to implement the Toffoli gate using an array of coupled cavities with one three-level atom in each cavity. The large detuning between atoms and classical (quantum) fields plays an important role and the gate is implemented in one-step. The quantum information is encoded into the low-lying states of identical atoms and it is convenient to address qubit individually. Based on the Markovian master equation, it is shown that the scheme to implement the Toffoli gate is robust against the decoherence.

Abstract
Autoantibodies against poly-U-binding factor 60 kDa protein (PUF60) have been reported in Caucasian dermatomyositis (DM) patients. However, their clinical significance in idiopathic inflammatory myopathy (IIM) remains to be fully clarified. Our objective was to analyze the prevalence and clinical significance of anti-PUF60 antibodies in a large cohort of Chinese IIM patients. In our study, 388 IIM patients, 301 disease controls, and 167 healthy controls (HCs) were involved. An enzyme-linked immunosorbent assay (ELISA) was developed to detect serum anti-PUF60 levels and was validated using immunoblotting methods. Unpaired Mann-Whitney U test and Spearman correlation analysis were used when appropriate. Anti-PUF60 antibodies were observed in IIM patients at a frequency of 10.6% (41/388). Subgrouping analysis revealed that the prevalence of anti-PUF60 antibodies was 10% in DM, 5.5% in polymyositis (PM), 10% in immune-mediated necrotizing myositis (IMNM), and 26.5% in myositis-overlap syndrome. Anti-PUF60 antibodies were also observed in systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and Sjögren's syndrome (SS) patients at a positive rate of 17.3, 14.5, and 10.1% respectively. Intriguingly, anti-PUF60 antibodies were frequently observed in clinically amyopathic dermatomyositis (CADM) patients and DM patients without currently known myositis autoantibodies. Furthermore, DM patients with anti-PUF60 antibodies had higher prevalence of skin ulcerations. Moreover, longitudinal investigation in eight DM patients with anti-PUF60 antibodies revealed that the antibodies levels decreased with disease remission. Anti-PUF60 antibodies were nonspecific for myositis, since they could be detected in other rheumatic diseases. Further investigation of anti-PUF60 antibodies may reveal shared pathogenic pathways in systemic autoimmune disorders.

Abstract
Prostate cancer (PCa) is one of the most common male malignancies in the world. It was aimed to investigate differential expression of inflammatory and related factors in benign prostatic hyperplasia (BPH), prostate cancer (PCa), histological prostatitis (HP) and explore the role of Inducible nitric oxide synthase (iNOS), (VEGF) Vascular endothelial growth factor, androgen receptor (AR) and IL-2, IL-8 and TNF-α in the occurrence and development of prostate cancer. RT-PCR was used to detect the mRNA expression level of iNOS, VEGF, AR and IL-2, IL-8 and TNF-α in BPH, PCa and BPH+HP. Western blotting and immunohistochemical staining were used to detect the protein levels of various proteins in three diseases. The results showed the mRNA and protein levels of iNOS, VEGF and IL-2, IL-8 and TNF-α were significantly increased in PCa and BPH+HP groups compared with BPH group (p < .05), while the AR was significantly lower than those in PCa and BPH+HP groups (p < .05). There was no significant difference in the mRNA and protein levels of iNOS, VEGF, AR and IL-2, IL-8 and TNF-α between PCa and BPH+HP groups (p > .05). iNOS, VEGF, AR and IL-2, IL-8 and TNF-α are involved in the malignant transformation of prostate tissue and play an important role in the development and progression of Prostate cancer (PCa).

Abstract
Obiective: To explorethe correlation between Neo-Bioscore and disease-free survival (DFS) after neoadjuvant therapy in patients with breast cancer in China. Methods: The clinical and pathological data of 429 patients with early or locally advanced breast cancer who received neoadjuvant therapy at the No.307 Hospital of PLA from January 1, 2005 to December 31, 2015 were analyzed and we followed up their DFS. Results: Neo-Bioscore were closely related to DFS (χ(2)=47.662, P<0.001). When the groups were divided by Neo-Bioscore 3, they weremore relevantto DFS (HR=5.093 vs HR=2.044), equivalent tothe role of traditional recurrence risk grouping in guiding the choice of adjuvantendocrine regimen for hormone receptor (HR) positive patients who were premenopausalafter neoadjuvant chemotherapy, andmore relevantto DFS than whetherthe pathologic complete response (pCR)grouping in the same molecular pathology subgroup of HR positive/human epidermal growth factor receptor 2 (HER-2)negative (P<0.001 vs P=0.166), HER-2 positive (P<0.001 vs P=0.166), HRnegative/HER-2 negative (P<0.001 vs P=0.166). Conclusions: Neo-Bioscore could be used as an early indicator of predicting DFS for breast cancer patients after neoadjuvant therapy.When the groups were divided by Neo-Bioscore 3, they were more relevant to DFS, equivalent to the role of traditional recurrence risk grouping in guiding the choice of adjuvantendocrine regimen for premenopausal HR positive patients, andmore relevantto DFS than whetherthe pCRgrouping in the same molecular pathology subgroup.

Abstract
OBJECTIVES To evaluate the value of whole-body magnetic resonance imaging (WBMRI) in diagnosing muscular and extra muscular lesions in patients with polymyositis (PM) and dermatomyositis (DM). METHODS A retrospective analysis of WBMRI data from PM/DM patients who met the Bohan and Peter diagnostic criteria was performed. X2 test was used to compare the rate of positive diagnosis of newly diagnosed patients using WBMRI, serum creatine kinase test, and EMG. McNemar test was used to compare the performance of WBMRI and chest CT in detecting interstitial lung disease (ILD). RESULTS The study included 129 patients (30 PM cases and 99 DM cases). Of them, 81.4% (105/129) showed a visible inflammatory muscular edema on their WBMRI; 29.5% (38/129) had varying degrees of fatty infiltration (9 cases with clear muscular atrophy). Of the 66 newly diagnosed patients, the positive rates of WBMRI, muscle biopsy, serum creatine kinase test and EMG were 86.4% (57/66), 92.4% (61/66), 71.2% (47/66) and 71.1% (32/45), respectively. There was no significant difference in the positive rates between WBMRI and muscle biopsy (X2 = 1.28, P = 0.258). The WBMRI had a higher positive rate than both serum creatine kinase test (X2 = 4.53, P = 0.033) and EMG (X2 = 3.92, P = 0.047). In addition to muscular changes, WBMRI also detected interstitial lung disease (ILD) in 38 cases (29.5%), osteonecrosis in 15 cases (11.6%), and neoplastic lesions (5 malignant; 7 benign) in 12 cases (9.3%). Of the 61 patients who underwent routine chest CT examinations, the WBMRI and CT revealed ILD in 29 cases and 35 cases respectively. There was no significant difference in the sensitivity between WBMRI and CT (p = 0.146). CONCLUSIONS WBMRI is a sensitive, non-invasive and efficient imaging method. It comprehensively displays the extent of muscular involvement in PM/DM patients, and it has the ability to diagnose other associated extra muscular diseases, such as ILD and systemic malignancy. WBMRI can also help screen steroid-induced osteonecrosis.

Abstract
OBJECTIVE To investigate the feasibility and accuracy of T2 weighted spectral pre-saturation inversion recovery combined with fluid-attenuated inversion recovery (T2W SPIR-FLAIR) in the diagnosis of hip synovitis in patients with spondyloarthritis (SpA). METHODS 10 volunteers underwent a T2W SPIR and 4 T2W SPIR-FLAIR sequence scans with different inversion times (TIs) to determine the optimum TI that could effectively suppress the intra-articular fluid signals. Hip MRI including T2W SPIR-FLAIR and enhanced T1 weighted (T1W) SPIR sequences was performed in 45 patients with SpA and totally 90 hips were evaluated. McNemar's test and Kappa test were used to compare the diagnostic results of synovitis between T2W SPIR-FLAIR and enhanced T1W SPIR. RESULTS A TI of 2100 ms was selected as the optimum TI. 32 hips from 17 patients exhibited high signal intensity within the articular cavity on both T2W SPIR-FLAIR and enhanced T1W SPIR sequences, while only 3 hips showed high signals within the articular cavity on T2W SPIR-FLAIR. The remaining 55 hips did not show high signals within the articular cavity on both sequences. The T2W SPIR-FLAIR and enhanced T1W SPIR sequences had similar values in the diagnosis of hip synovitis (p = 0.25) and a high degree of diagnostic consistency (Kappa = 0.929). CONCLUSION T2W SPIR-FLAIR can effectively suppress the intra-articular fluid signals, while retaining the signals of thickened synovial membranes and can be used for the diagnosis of hip synovitis in patients with SpA. Advances in knowledge: The enhanced T1W SPIR is a classic sequence for synovitis diagnosis, but it requires the injection of contrast agents. The T2W SPIR-FLAIR and enhanced T1W SPIR sequences had similar values in the diagnosis of hip synovitis (p = 0.25) and a high degree of diagnostic consistency (Kappa = 0.929).

Abstract
Effects of human selenoprotein SelK on the adhesion and migration ability of human gastric cancer BGC-823 cells using Matrigel adhesion and transwell migration assays, respectively, were investigated in this study. The Matrigel adhesion ability of BGC-823 cells that overexpressed SelK declined extremely significantly (p < 0.01) compared with that of the cells not expressing the protein. The migration ability of BGC-823 cells that overexpressed SelK also declined extremely significantly (p < 0.01). On the other hand, the Matrigel adhesion ability and migration ability of the cells that overexpressed C-terminally truncated SelK did not decline significantly. The Matrigel adhesion ability and migration ability of human embryonic kidney HEK-293 cells that overexpressed SelK did not show significant change (p > 0.05) with the cells that overexpressed the C-terminally truncated protein. In addition to the effect on Matrigel adhesion and migration, the overexpression of SelK also caused a loss in cell viability (as measured by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H tetrazolium bromide (MTT) colorimetric assay) and induced apoptosis as shown by confocal microscopy and flow cytometry. The cytosolic free Ca2+ level of these cells was significantly increased as detected by flow cytometry. But the overexpression of SelK in HEK-293 cells caused neither significant loss in cell viability nor apoptosis induction. Only the elevation of cytosolic free Ca2+ level in these cells was significant. Taken together, the results suggest that the overexpression of SelK can inhibit human cancer cell Matrigel adhesion and migration and cause both the loss in cell viability and induction of apoptosis. The release of intracellular Ca2+ from the endoplasmic reticulum might be a mechanism whereby the protein exerted its impact. Furthermore, only the full-length protein, but not C-terminally truncated form, was capable of producing such impact. The embryonic cells were not influenced by the elevation of free Ca2+ level in cytosol, probably due to their much greater tolerance to the variation.

Abstract
Objective: To investigate the effects of desmopressin acetate and pituitrin on the proliferation, contraction, and secretion of hepatic stellate cells (HSCs). Methods: The human HSC cell line LX-2 was selected as the research model. And three groups were designed: blank control group, desmopressin acetate group (three subgroups: 1×10-10mol/L, 1×10-9mol/L, and 1×10-8mol/L desmopressin acetate), and pituitrin group (three subgroups: 0.1 U/L, 1.0 U/L, and 10.0 U/L pituitrin). Water-soluble tetrazolium salt (WST)-1 assay was used to evaluate cell proliferation; collagen gel contraction assay was used to assess cell contraction; enzyme-linked immunosorbent assay (ELISA) was used to identify cell secretion. The data was subjected to one-way analysis of variance. Results: (1) The results of WST-1 assay showed that the values of A450in three desmopressin acetate subgroups (1×10-10mol/L, 1×10-9mol/L, and 1×10-8mol/L) were 0.459±0.017, 0.467±0.024, and 0.436±0.015, respectively. And the values of A450 in three pituitrin subgroups (0.1 U/L, 1.0 U/L, and 10.0 U/L) were 0.495±0.011, 0.507±0.015, and 0.501±0.009, respectively. Compared with the control group, the desmopressin acetate at high concentration significantly inhibited the cell proliferation (P< 0.05), but the pituitrin at three different concentrations significantly promoted the cell proliferation (P< 0.05). (2) The collagen gel area ratios in three desmopressin acetate subgroups (1×10-10mol/L, 1×10-9mol/L, and 1×10-8mol/L) were 77.07±4.42, 75.85±3.70, and 72.74±3.92, respectively. And the collagen gel area ratios in three pituitrin subgroups (0.1 U/L, 1.0 U/L, and 10.0 U/L) were 57.83±3.96, 50.28±6.69, and 43.56±7.68, respectively. Compared with the control group, the pituitrin at three different concentrations significantly reduced the collagen gel area (P< 0.01). (3) The matrix metalloproteinase(MMP)-2 concentrations in three desmopressin acetate subgroups (1×10-10mol/L, 1×10-9mol/L, and 1×10-8mol/L) were 13.321±0.098, 12.230±0.153, and 12.061±0.126, respectively. And the MMP-2 concentrations in three pituitrin subgroups (0.1 U/L, 1.0 U/L, and 10.0 U/L) were 12.899±0.150, 13.662±0.152, and 13.698±0.119, respectively. Compared with the control group, the desmopressin acetate at low concentration significantly increased the secretion of MMP-2 (P< 0.01); the desmopressin acetate at high concentration significantly decreased the MMP-2 concentration (P< 0.05); the pituitrin at three different concentrations significantly increased the MMP-2 concentration (P< 0.01). The transforming growth factor-beta 1 (TGF-β1) concentrations in three desmopressin acetate subgroups (1×10-10mol/L, 1×10-9mol/L, and 1×10-8mol/L) were 5.233±0.102, 17.749±0.188, and 36.060±0.227, respectively. And the TGF-β1 concentrations in three pituitrin subgroups (0.1 U/L, 1.0 U/L, and 10.0 U/L) were 15.615±0.099, 38.460±0.209, and 49.053±0.115, respectively. Compared with the control group, desmopressin acetate and pituitrin significantly promoted the secretion of TGF-β1 in a concentration-dependent manner (P< 0.01) and pituitrin had a stronger effect than desmopressin acetate (P< 0.01). Desmopressin acetate and pituitrin had no effect on the secretion of the collagenase type I and III (P> 0.05). Conclusion: Desmopressin acetate and pituitrin can induce the changes in the function and morphology of HSCs and may increase vascular resistance in the hepatic sinus. However, desmopressin acetate has less influence on HSCs than pituitrin.

Abstract
The objective of the study was to evaluate the efficacy and safety of etanercept (Anbainuo) treatment in Chinese moderate to severe rheumatoid arthritis (RA) with inadequate response to methotrexate (MTX-IR); 600 patients (360 in phase III-1 and 240 in phase III-2) poorly responding to MTX were enrolled in the study and randomized at a ratio of 2:1 into an Anbainuo treatment or control group. The study was designed as a 12-week double-blind, placebo-controlled period followed by a 12-week open-label study. The primary endpoint was the ACR20 response rate at week 12. Secondary endpoints included the ACR50, ACR70, ACR-N, and safety. At week 12, ACR20 response was observed in 60.9 % of the Anbainuo group-significantly higher than that of the control group (20.6 %). At week 24, the ACR20 response in the Anbainuo group increased to 70.2 %; there was no significant difference compared with that of the control group (61.8 %, P > 0.05). At week 12, the ACR50 and ACR70 responses of the Anbainuo group increased to 25.6 and 6.8 %, compared to 4 and 1 % in the control group (P < 0.001, P = 0.002). The ACR-N was 2.85 ± 6.73 vs. -3.24 ± 8.78 % in the control group (P < 0.001). During the first 12 weeks of treatment, 66 adverse events (AE) were reported in the Anbainuo group (15.6 %) and 21 AEs (10.5 %) occurred in the control group, whereby the rate of the Anbainuo group was slightly higher than the control group (P = 0.042). Severe adverse events (SAEs) occurred in the Anbainuo group (1.3 %) and one (SAE) occurred in the control group (0.5 %) (P = 0.19). Anbainuo displays a rapid onset of efficacy as well as good tolerance and safety in MTX-IR patients having moderate to severe RA.

Abstract
The quantum phase transition (QPT) describes a sudden qualitative change of the macroscopic properties mapped from the eigenspectrum of a quantum many-body system. It has been studied intensively in quantum systems with the spin-boson model, but it has barely been explored for systems in coupled spin-boson models. In this paper, we study the QPT with coupled spin-boson models consisting of coupled two-level atoms embedded in three-dimensional anisotropic photonic crystals. The dynamics of the system is derived exactly by means of the Laplace transform method, which has been proven to be equivalent to the dissipationless non-Markovian dynamics. Drawing on methods for analyzing the ground state, we obtain the phase diagrams through two exact critical equations and two QPTs are found: one QPT is that from the phase without one bound state to the phase with one bound state and another is that from one phase with the bound state having one eigenvalue to another phase where the bound state has two eigenvalues. Our analytical results also suggest a way of control to overcome the effect of decoherence by engineering the spectrum of the reservoirs to approach the non-Markovian regime and to form the bound state of the whole system for quantum devices and quantum statistics.

Abstract
A laser ion source based on Nd:YAG laser has been being studied at the Institute of Modern Physics for the production of high intensity high charge state heavy ion beams in the past ten years, for possible applications both in a future accelerator complex and in heavy ion cancer therapy facilities. Based on the previous results for the production of multiple-charged ions from a wide range of heavy elements with a 3 J/8 ns Nd:YAG laser [Zhao et al., Rev. Sci. Instrum. 85, 02B910 (2014)], higher laser energy and intensity in the focal spot are necessary for the production of highly charged ions from the elements heavier than aluminum. Therefore, the laser ion source was upgraded with a new Nd:YAG laser, the maximum energy of which is 8 J and the pulse duration can be adjusted from 8 to 18 ns. Since then, the charge state distributions of ions from various elements generated by the 8 J Nd:YAG laser were investigated for different experimental conditions, such as laser energy, pulse duration, power density in the focal spot, and incidence angle. It was shown that the incidence angle is one of the most important parameters for the production of highly charged ions. The capability of producing highly charged ions from the elements lighter than silver was demonstrated with the incidence angle of 10° and laser power density of 8 × 10(13) W cm(-2) in the focal spot, which makes a laser ion source complementary to the superconducting electron cyclotron resonance ion source for the future accelerator complex especially in terms of the ion beam production from some refractory elements. Nevertheless, great efforts with regard to the extraction of intense ion beams, modification of the ion beam pulse duration, and reliability of the ion source still need to be made for practical applications.

Abstract
AIMS Mechanisms for carbon fixation via photosynthesis in the diatom Phaeodactylum tricornutum Bohlin were studied recently but there remains a long-standing debate concerning the occurrence of C4 photosynthesis in this species. A thorough investigation of carbon metabolism and the evidence for C4 photosynthesis based on organelle partitioning was needed. METHODS AND RESULTS In this study, we identified the flux ratios between C3 and C4 compounds in P. tricornutum using (13)C-labelling metabolic flux ratio analysis, and stained cells with various cell-permeant fluorescent probes to investigate the likely organelle partitioning required for single-cell C4 photosynthesis. Metabolic flux ratio analysis indicated the C3/C4 exchange ratios were high. Cell staining indicated organelle partitioning required for single-cell C4 photosynthesis might exist in P. tricornutum. CONCLUSION The results of (13)C-labelling metabolic flux ratio analysis and cell staining suggest single-cell C4 photosynthesis exists in P. tricornutum. SIGNIFICANCE AND IMPACT OF THE STUDY This study provides insights into photosynthesis patterns of P. tricornutum and the evidence for C4 photosynthesis based on (13)C-labelling metabolic flux ratio analysis and organelle partitioning.

Abstract
We propose a scheme of photon blockade in a system comprising of coupled cavities embedded in Kerr nonlinear material, where two cavities are driven and dissipated. We analytically derive the exact optimal conditions for strong photon antibunching, which are in good agreement with those obtained by numerical simulations. We find that conventional and unconventional photon blockades have controllable flexibilities by tuning the strength ratio and relative phase between two complex driving fields. Such unconventional photon-blockade effects are ascribed to the quantum interference effect to avoid two-photon excitation of the coupled cavities. We also discuss the statistical properties of the photons under given optimal conditions. Our results provide a promising platform for the coherent manipulation of photon blockade, which has potential applications for quantum information processing and quantum optical devices.

Abstract
Objective.To investigate serum levels of soluble CD163 (sCD163) in patients with polymyositis (PM) and dermatomyositis (DM), and to correlate these to clinical manifestations and laboratory data.Methods.Serum levels of sCD163 were detected in 24 patients with PM, 84 patients with DM, and 46 healthy controls by using the ELISA method. Immunohistochemistry staining of macrophage infiltration in muscle tissue using anti-CD163 monoclonal antibody was conducted on muscle biopsy specimens from 13 patients with PM and 17 with DM.Results.Serum levels of sCD163 were significantly increased in patients compared with healthy controls (p < 0.001). Patients with interstitial lung disease (ILD) had statistically higher sCD163 levels than patients without ILD (p < 0.001). High serum sCD163 levels were associated with increased incidence of antinuclear antibody (p < 0.05), higher serum levels of immunoglobulin G (p < 0.01) and immunoglobulin A (p < 0.05), and increased erythrocyte sedimentation rates (p < 0.01). Serum sCD163 levels were inversely correlated with CD3+ T cell counts in peripheral blood of patients (r = −0.306, p < 0.01). Cross-sectional assessment and longitudinal study revealed a significant correlation between serum sCD163 levels and disease activity. Patients with high serum sCD163 levels showed a higher incidence of CD163+ macrophage infiltration in muscle tissue than patients with normal sCD163 levels (chi-square value = 10.804, p < 0.01).Conclusion.Serum levels of sCD163 were significantly elevated and correlated with disease severity in patients with PM/DM, suggesting serum sCD163 as a promising biomarker in the disease evaluation of PM/DM. Our finding of elevated serum sCD163 levels associated with muscle macrophage infiltration highlights the role activated macrophage plays in the pathogenesis of PM/DM.

Abstract
The epidemiological characteristics of Sjögren syndrome (SS) are significantly varied in different countries. We conducted the present study to survey the epidemiological characteristics of primary SS in China. We recruited 483 primary SS patients from 16 Chinese medical centers nationwide from January 2009 to November 2011 and assessed salivary and lacrimal gland dysfunction, organ involvement, and autoimmunity in these patients. The cohort included 456 women and 27 men (ratio, 17:1; mean age at onset, 42 ± 11 years; median age at diagnosis, 49 years; range, 41-56 years). Male patients showed a lower frequency of xerophthalmia (37.0% vs 60.7%) and a higher frequency of arthritis (40.7% vs 16.4%). Young-onset patients showed a higher frequency of low C3 levels (57.7% vs 36.3%) and pancytopenia (22.2% vs 8.8%). Patients with systemic involvement had a higher frequency of immunoglobulin A (IgA) (39.4% vs 22.5%) and immunoglobulin M (IgM) (12.4% vs 37.9%). Patients with pulmonary involvement had a higher parotid enlargement (21.4% vs 10.2%), purpura (12.1% vs 5.7%) and higher anti-La/SS-B (61.7% vs 41.8%), immunoglobulin G (IgG) (80.7% vs 64.6%) and IgA (48.9% vs 30.6%) levels. Patients with anti-Ro/SSA antibodies had more frequent exocrine gland symptoms and some extraglandular symptoms and immunological alterations. Compared with previous studies performed in other countries, SS patients in China showed particular clinical manifestation, systemic involvement, and immunological alterations.

Abstract
AIM To investigate serum levels of B-cell activating factor (BAFF) in the patients with polymyositis (PM) and dermatomyositis (DM), and to systematically examine the association between serum BAFF levels and disease activity in PM/DM patients. PATIENTS & METHODS A cross-sectional analysis included 92 PM/DM patients and 25 healthy control subjects. A longitudinal study followed 24 patients. Serum BAFF concentrations were detected by the ELISA method. RESULTS Serum BAFF levels in PM/DM patients were significantly higher than those in healthy controls. A cross-sectional assessment revealed a modest correlation between serum BAFF levels and global disease activity and a mild correlation between serum BAFF levels and muscle disease activity. The longitudinal study showed that serum BAFF levels modestly correlated with global disease activity and muscle disease activity. CONCLUSION Resulting data showed high serum BAFF levels in PM/DM patients and suggested BAFF as a serological biomarker for PM/DM disease activity.
