Abstract
OBJECTIVE Manganese ion (Mn2+ ) is reported to promote the antitumor immune response by activating the cGAS-STING pathway, but it is unknown whether Mn2+ can prevent the malignant transformation of precancerous lesions. The effects of Mn2+ in treating oral leukoplakia (OLK) were explored in this work. METHODS Peripheral blood Mn analysis of the patients was performed using inductively coupled plasma atomic emission spectroscopy (ICP-AES). A coculture model of dendritic cells (DCs)/macrophages, CD8+ T cells, and dysplastic oral keratinocytes (DOKs) was employed to analyze the role and mechanism of Mn2+ in a simulated OLK immune microenvironment. Western blot, RT-PCR, flow cytometry, enzyme-linked immunosorbent assay (ELISA), and lactate dehydrogenase (LDH) assays were adopted to detect the mechanism of Mn2+ in this model. 4-nitroquinoline oxide (4NQO)-induced OLK mice were used to assess the role of Mn2+ in suppressing OLK progression, and a novel Mn2+ -loaded guanosine-tannic acid hydrogel (G-TA@Mn2+ hydrogel) was fabricated and evaluated for its advantages in OLK therapy. RESULTS The content of Mn in patients' peripheral blood was negatively related to the progression of OLK. Mn2+ promoted the maturation and antigen presentation of DCs and macrophages and enhanced the activation of CD8+ T cells in the coculture model, resulting in effective killing of DOKs. Mechanistic analysis found that Mn2+ enhanced the anti-OLK immune response by activating the cGAS-STING pathway. Moreover, Mn2+ suppressed the development of 4NQO-induced carcinogenesis in the mouse model. In addition, the G-TA@Mn2+ hydrogel had better anti-OLK effects. CONCLUSIONS Mn2+ enhanced the anti-OLK immune response by activating the cGAS-STING pathway, and the G-TA@Mn2+ hydrogel is a potential novel therapeutic approach for OLK treatment.

Abstract
Lichen planus pemphigoides (LPP) is a rare autoimmune subepidermal disease that can occur in patients receiving immune checkpoint inhibitors. Its clinical manifestations are combined with the characteristics of lichen planus with bullous pemphigoid that can occur on either skin or oral mucosa. It should be noted that oral LPP is very rare. Here, we report a novel case of oral LPP induced by an anti-PD-1 agent. The patient presented with typical clinical features in oral mucosa, and the diagnosis was based on histopathology and immunological studies. Given that the patient was receiving an anti-PD-1 agent, topical therapy was chosen, and a nice therapeutic effect was obtained. No significant recurrence was observed after a 2-year follow-up. A good and stable therapeutic effect achieved by rapid and local symptomatic medication suggests that accurate and sensitive diagnosis is necessary.

Abstract
Exotic spin-dependent interactions involving new light particles address key questions in modern physics. Interactions between polarized neutrons (n) and unpolarized nucleons (N) occur in three forms: g_{S}^{N}g_{P}^{n}σ·r, g_{V}^{N}g_{A}^{n}σ·v, and g_{A}^{N}g_{A}^{n}σ·v×r, where σ is the spin and g's are the corresponding coupling constants for scalar, pseudoscalar, vector, and axial-vector vertexes. If such interactions exist, the Sun and Moon could induce sidereal variations of effective fields in laboratories. By analyzing existing data from laboratory measurements on Lorentz and CPT violation, we derive new experimental upper limits on these exotic spin-dependent interactions at astronomical ranges. Our limits on g_{S}^{N}g_{P}^{n} surpass the previous combined astrophysical-laboratory limits, setting the most stringent experimental constraints to date. We also report new constraints on vector-axial-vector and axial-axial-vector interactions at astronomical scales, with vector-axial-vector limits improved by ∼12 orders of magnitude. We extend our analysis to Hari Dass interactions and obtain new constraints.

Abstract
In 2021, a total of 151 pregnant women were selected from the suburb of Shanghai. A questionnaire survey was conducted to obtain data about maternal age, gestational week, total annual household income, education level and passive smoking among pregnant women and one spot urine was collected. The concentrations of eight neonicotinoid pesticides and four metabolites in urine were measured by ultra-high performance liquid chromatography-tandem quadrupole time-of-flight mass spectrometry. The differences in detection frequencies and concentrations of neonicotinoid pesticides and their metabolites among pregnant women with different characteristics were compared, and the influencing factors of the detection of neonicotinoid pesticides in urine were analyzed. The results showed that at least one neonicotinoid pesticide was detected in 93.4% (141 samples) of urine samples. The detection frequencies of N-desmethyl-acetamiprid, clothianidin, thiamethoxam, and N-desmethyl-clothianidin were high, about 78.1% (118 samples), 75.5% (114 samples), 68.9% (104 samples), and 44.4% (67 samples), respectively. The median concentration of the sum of all neonicotinoid pesticides was 2.66 μg/g. N-desmethyl-acetamiprid had the highest detection concentration with a median concentration of 1.04 μg/g. A lower urinary detection frequency of imidacloprid and its metabolites was seen in pregnant women aged 30-44 years [OR (95%CI): 0.23 (0.07-0.77)]. A higher detection frequency of clothianidin and its metabolites was seen in pregnant women with per capita annual household income≥100, 000 yuan [OR (95%CI): 6.15 (1.56-24.28)]. There was widespread exposure to neonicotinoid pesticides and their metabolites in pregnant women from the suburb of Shanghai, which might pose potential health risks to pregnant women, and maternal age and household income were potential influencing factors of the exposure to neonicotinoid pesticides.

Abstract
We retrospectively included 53 (9 males, 44 females) patients who underwent rest urethral pressure profilometry (RUPP) due to lower urinary tract symptoms (LUTS) in Beijing Chaoyang Hospital from May 2021 to March 2022. The age of patients was (55±16) (25-76) years old. The clinical diagnoses of the included patients with lower urinary tract symptoms were classified as: benign prostatic hyperplasia in 9 cases, interstitial cystitis in 1 case, stress urinary incontinence in 11 cases and non-obstructive dysuria in 32 cases. The full set of urodynamic examination was composed of bladder pressure measurement during the filling period, pressure flow study (PFS) and RUPP. All the urodynamic examination was performed by air-charged catheter (ACC) and corresponding equipment. All patients underwent RUPP measurements twice. The vesical pressure (Pves) values were (35.30±6.15), (35.81±5.91) cmH2O (1 cmH2O=0.098 kPa); the Pura@max were (141.91±36.53), (145.02±38.85) cmH2O; functional urethral length were (41.70±16.34), (42.55±16.40) mm; the maximum urethral closure pressure for the two RUPP measurements were (106.57±36.44), (109.41±39.27) cmH2O. There was no statistical difference between the two RUPP measurements (P>0.05). The reproducibility of the RUPP measurements obtained by ACC is good and deserves further study.

Abstract
To meet the challenges posed by global arsenic water contamination, the MgAlMn-LDHs with extraordinary efficiency of arsenate removal was developed. In order to clarify the enhancement effect of the doped-Mn on the arsenate removal performance of the LDHs, the cluster models of the MgAlMn-LDHs and MgAl-LDHs were established and calculated by using density functional theory (DFT). The results shown that the doped-Mn can significantly change the electronic structure of the LDHs and improve its chemical activity. Compared with the MgAl-LDHs that without the doped-Mn, the HOMO-LUMO gap was smaller after doping. In addition, the -OH and Al on the laminates were also activated to improve the adsorption property of the LDHs. Besides, the doped-Mn existed as a novel active site. On the other hand, the MgAlMn-LDHs with the doped-Mn, the increased of the binding energy, as well as the decreased of the ion exchange energy of interlayer Cl-, making the ability to arsenate removal had been considerably elevated than the MgAl-LDHs. Furthermore, there is an obvious coordination covalent bond between arsenate and the laminates of the MgAlMn-LDHs that with the doped-Mn.

Abstract
Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

Abstract
Objective: To evaluate the efficacy and safety of selective genicular artery embolization for the treatment of the knee pain secondary to osteoarthritis. Methods: From October 2020 to July 2021, 17 patients (23 knees) aged (68±7) years with moderate to severe knee pain secondary to knee osteoarthritis were prospectively included in the General Hospital of Ningxia Medical University. There were 6 males and 11 females included in this research. Patients were assessed with knee pain, stiffness, and function with the Visual Analogue Scale (VAS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at baseline, using the Kellgren-Lawrence (K-L) grading to evaluate the severity of KOA, and using the Magnetic Resonance Knee Osteoarthritis Score (MOAKS) to evaluate the MR imaging characteristics of the affected knee. Selective genicular artery embolization (GAE) was performed in all patients. The patients were followed up for 6 months after the procedure. Patients were assessed with the VAS score and WOMAC scale at 1 d, 1 week and 1, 3 and 6 months after the procedure to evaluate the clinical outcomes, including the improvement of knee joint pain, stiffness and function, as well as the occurrence of adverse reactions. Results: Three to seven genicular artery branches were superselected and embolized in 23 knees, and 4 to 7 genicular artery branches were embolized in 7 patients with K-L grade 4. The clinical improvement was 95.6% (22/23) at 1 month, 86.9% (20/23) at 3 months, and 91.3% (21/23) at 6 months. Twenty-three knees completed the 6-month follow-up, and the VAS score, WOMAC pain score, and total WOMAC score at 1, 3, and 6 months after surgery were (2.5±1.3), (3.4±2.4), and (19.7±9.8) points, (3.0±1.8), (4.5±3.4), and (22.3±11.3) points, (2.8±1.5), (4.1±3.0), and (20.5±11.0) points, which were lower than the (6.6±0.9), (11.4±2.6) and (47.0±12.0) points at baseline (all P<0.001). During the follow-up period, 7 patients had adverse reactions: 3 cases had skin ecchymosis in the femoral artery puncture area, 4 cases had knee joint stiffness and pain within 1 day after operation, which were relieved spontaneously in 1 week, 6 patients had joint clicking during extension and flexion activities after operation, of which 3 cases subsided spontaneously within 3 months after operation. None of the patients had major procedure-related adverse events. Conclusion: GAE has a high clinical improvement rate and a low incidence of adverse reactions in the treatment of the pain secondary to knee osteoarthritis, which provides a new treatment option for patients who fail to respond to conservative treatment.

Abstract
Cancer-associated fibroblasts (CAFs) are highly heterogeneous and differentiated stromal cells that promote tumor progression via remodeling of extracellular matrix, maintenance of stemness, angiogenesis, and modulation of tumor metabolism. Aerobic glycolysis is characterized by an increased uptake of glucose for conversion into lactate under sufficient oxygen conditions, and this metabolic process occurs at the site of energy exchange between CAFs and cancer cells. As a hallmark of cancer, metabolic reprogramming of CAFs is defined as reverse Warburg effect (RWE), characterized by increased lactate, glutamine, and pyruvate, etc. derived from aerobic glycolysis. Given that the TGF-β signal cascade plays a critical role in RWE mainly through metabolic reprogramming related proteins including pyruvate kinase muscle isozyme 2 (PKM2), however, the role of nuclear PKM2 in modifying glycolysis remains largely unknown. In this study, using a series of in vitro and in vivo experiments, we provide evidence that TGF-βRII overexpression suppresses glucose metabolism in CAFs by attenuating PKM2 nuclear translocation, thereby inhibiting oral cancer tumor growth. This study highlights a novel pathway that explains the role of TGF-βRII in CAFs glucose metabolism and suggests that targeting TGF-βRII in CAFs might represent a therapeutic approach for oral cancer.

Abstract
Objective: To explore the distribution characteristics of pathogens in adult patients with community-acquired pneumonia (CAP) and to provide basis for the diagnosis, treatment, prevention of CAP. Methods: 1 446 inpatients with CAP were prospectively enrolled in a third-class hospital in Beijing in recent 5 years (from January 2015 to December 2019). Respiratory tract samples were collected for smear, culture, nucleic acid, antigen and antibody detection to identify the pathogen of CAP. Mann-Whitney U test was used for continuous variables and χ2 test or Fisher's exact test was used for categorical data for statistical analysis. Results: Among the 1 446 patients, 822 (56.85%) patients were infected with a single pathogen, 231 (15.98%) patients were infected with multiple pathogens, and 393 (27.18%) patients were not clear about the pathogen. Influenza virus is the first pathogen of CAP (20.95%, 303/1 446), mainly H1N1 (8.51%, 123/1 446), followed by mycoplasma pneumoniae (7.19%, 104/1 446), Mycobacterium tuberculosis (5.33%, 77/1 446) and Streptococcus pneumoniae (5.05%, 73/1 446). The outbreak of H1N1 occurred from December 2018 to February 2019, and the epidemic of mycoplasma pneumoniae pneumonia was monitored from August to November 2019. Patients under 65 years old had high detection rates of Mycoplasma pneumoniae (14.41% vs. 2.41%, χ²=74.712,P<0.001), Streptococcus pneumoniae (8.16% vs. 2.99%, χ²=18.156, P<0.001), rhinovirus (6.08% vs. 3.56%, χ²=5.025, P<0.025), Chlamydia pneumoniae (5.90% vs. 1.15%, χ²=26.542, P<0.001) and adenovirus (3.13% vs. 0.92%, χ²=9.547, P=0.002). The severe disease rate of CAP was 14.66% (212/1 446), and the average mortality rate was 3.66% (53/1 446). The severe illness rate and mortality rate of bacterial-viral co-infection were 28.97% (31/107) and 19.63% (21/107), respectively. Conclusions: Influenza virus is the primary pathogen of adult CAP. Outbreaks of Mycoplasma pneumoniae and H1N1 were detected in 2018 and 2019, respectively. The remission rate and mortality rate of virus-bacteria co-infection were significantly higher than those of single pathogen infection. Accurate etiological basis not only plays a role in clinical diagnosis and treatment, but also provides important data support for prevention and early warning.

Abstract
Objective: To explore the serum cyclic polypeptide biomarkers for ovarian cancer diagnosis. Methods: A total of 54 patients with epithelial ovarian cancer confirmed by pathology in Cancer Hospital, Chinese Academy of Medical Sciences from March 2018 to September 2018 were selected as the study subjects, and 40 healthy women with normal examination results in the cancer screening center were selected as the control. All of the samples were randomly divided into training set and validation set at the ratio of 1∶1 with a random number. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) combined with magnetic bead technology was used for detecting peptide profiling in serum samples to screen significantly differently expressed peptides between ovarian cancer group and control group of the training set (score>5). Receiver operating characteristic (ROC) curve analysis was used to screen differential peptide peaks with area under curve (AUC) ≥0.8, sensitivity and specificity>90% in the training set and validation set. Liquid chromatography-mass spectrometry (LC-MS/MS) was further used to determine the composition of differentially expressed peptides. Results: By comparing the peptide profiles of the two groups, 102 differential peptide peaks were initially detected in the mass-to-charge ratio range of 1 000 to 10 000. ROC curve analysis showed that there were 42 differential peptide peaks with AUC ≥0.8 in both training set and validation set, 19 of which were highly expressed in ovarian cancer group, and 23 were lowly expressed. There were 15 different peptide peaks in highly expressed ovarian cancer group with sensitivity and specificity over 90%. The mass-to-charge ratios were 7 744.27, 5 913.41, 5 329.87, 4 634.21, 4 202.02, 3 879.26, 3 273.35, 3 253.79, 3 234.34, 2 950.33, 2 664.51, 2 018.38, 1 893.37, 1 498.69 and 1 287.55. There were 15 different peptide peaks in lowly expressed ovarian cancer group with sensitivity and specificity over 90%, the mass-to-charge ratios were 9 288.46, 7 759.77, 5 925.24, 4 652.77, 4 210.42, 3 887.02, 3 279.90, 3 240.82, 2 962.15, 2 932.70, 2 022.42, 1 897.16, 1 501.69, 1 337.38 and 1 290.13. No protein composition was identified in 15 different peptide peaks in lowly expressed ovarian cancer group. The two protein compositions identified in 15 different peptide peaks in highly expressed ovarian cancer group were recombinant serglycin (SRGN) and fibinogen alpha chain (FGA), the mass-to-charge ratios of which were 1 498.696 and 5 913.417, respectively. The sensitivity and specificity of the two proteins for ovarian cancer diagnosis were 100%, 100% and 90.9%, 100%, respectively. Conclusion: SRGN and FGA are highly expressed in the serum of ovarian cancer patients, which may be potential diagnostic markers for ovarian cancer.

Abstract
Objective: To explore the clinical features of poly ADP-ribose polymerase (PARP) inhibitor-related anemia in advanced and relapsed epithelial ovarian cancer (EOC). Methods: Patients diagnosed with advanced or relapsed EOC and treated with PARP inhibitor at National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between January 2015 to October 2020 were accrued. The data included PARP inhibitors, treatment details, and lab tests before treatment and during treatment were collected and the clinical characteristics of PARP inhibitor-related anemia were analyzed. Results: (1) A total of 98 patients with a median age of 56.5 years old (30-82 years old) were enrolled in this study. All patients were treated with PARP inhibitor (65 cases of olaparib, 17 cases of niraparib, and 16 cases of fluzoparib). The median treatment duration was 37.5 weeks (4-119 weeks). (2) The anemia rate was 40% (39/98), including 5% (5/98) of grade Ⅰ, 14% (14/98) of grade Ⅱ, 11% (11/98) of grade Ⅲ, and 9% (9/98) of grade Ⅳ. Fourteen patients with pre-treatment grade Ⅰ anemia had a higher rate of anemia events than the 80 patients without pre-treatment anemia, 7/14 vs 35% (28/80; χ2=4.281, P=0.039). (3) The median anemia occurrence time was 7.0 weeks (1-52 weeks), including 41% (16/39) of anemia cases occurred in 1-4 weeks, 26% (10/39) occurred in 5-8 weeks, 13% (5/39) occurred in 9-12 weeks, 3% (1/39) occurred in 13-16 weeks, 10% (4/39) occurred in 17-20 weeks, 8% (3/39) occurred ≥21 weeks. At the time of the lowest hemoglobulin tested, the median value of mean corpuscular volume (MCV) was 106 fl,which was higher than the up limit of normal range (100 fl), 74% (29/39) of anemia patients had an elevated MCV level; the median value of mean corpuscular hemoglobin (MCH) was 36 pg, 54% (21/39) of anemia patients had an elevated MCH level; the median value of mean corpuscular hemoglobin concentration (MCHC) was 320 g/L, 69% (27/39) of anemia patients had a higher MCHC level; 92% (36/39) of anemia patients had a normal level of serum iron; 79% (31/39) of anemia patients had a normal level of transferrin. 74% (29/39) of the anemia patients were macrocytic orthochromatic anemia. (4) Among the 39 patients with anemia, 20 patients (51%, 20/39) withhold the treatment of PARP inhibitor due to grade Ⅲ or Ⅳ anemia, including 10 patients (50%, 10/20) who resumed the PARP inhibitor treatment by suppling iron, folate, and vitamin B12. The median stopping time of PARP inhibitor was 5.5 weeks (2-10 weeks), while the other 10 patients terminated the PARP inhibitor treatment for not recovering from severe anemia. Conclusions: One of the common adverse effects of PARP inhibitors is anemia, which mostly happened in the first 3 months of treatment. In the treatment of EOC, PARP inhibitor-related anemia mainly manifest as macrocytic orthochromatic anemia, and most patients with normal serum iron and transferrin.

Abstract
Objective: To study the clinical and etiological characteristics of viral pneumonia in patients with chronic obstructive pulmonary disease(VP-COPD), and to identify the risk factors associated with poor prognosis. Methods: From August 1, 2017 to August 1, 2019, totally 235 patients in a general hospital in Beijing were prospectively enrolled in this research, and all patients were diagnosed with viral pneumonia by imaging and etiology. The patients were divided into VP-COPD group(n=60) and VP-nCOPD(viral pneumonia in non-COPD patients) group(n=175). Pathogen detection and clinical characteristics were compared between the two groups.Finally, the binomial logistic regression was used to explore the risk factors associated with severe VP-COPD. Results: Compared with the VP-nCOPD group, the VP-COPD group was older(76.5 vs 66.0 years, P=0.001), and the CURB-65 score(2 vs 1, P= 0.001) and the PSI score(111 vs 85, P<0.001) were higher at admission. Pseudomonas aeruginosa(χ²= 10.308, P= 0.001) and Staphylococcus aureus(χ²= 5.953, P=0.028) were the most common co-infection bacteria. In the VP-COPD group type Ⅱ respiratory failure was more common(23.3% vs 6.8%, P<0.001), the number of severely ill patients was larger(48.3% vs 30.3%, P=0.011), the length of hospital stay was longer(13 vs 8, P<0.001), and the mortality rate during hospitalization was higher(18.3% vs 7.4%, P=0.016) in the VP-nCOPD group. Multivariate analysis showed that the level of blood glucose(OR: 1.73, 95%CI: 1.22-2.44, P= 0.002) and pleural effusion(OR: 133.12, 95%CI: 7.57-2 340.36, P=0.001) were risk factors for severe VP-COPD patients. Conclusion: Viral pneumonia in patients with COPD tended to develop into severe cases and had a poor prognosis.

Abstract
In order to remove and stabilize As(III) simultaneously from wastewater, a novel and effective method based on the in-situ formation of As(III)-containing Zn-Fe layered double hydroxides (ZnFe-As-LDHs) was developed. The influence of pH, Zn/Fe, Fe/As and adding rate on the formation of ZnFe-As-LDHs were investigated. Under the optimal conditions, the concentration of As(III) decreased from 100 to 0.13 mg/L and As leaching concentration of the ultimate sludge was 1.87 mg/L, which could meet the arsenic leaching criteria (5 mg/L) regulated by US EPA. Compared with the "ex-situ" sludge obtained by As(III) adsorbed on the pre-formed ZnFe-LDHs, the As(III) removal efficiency increased by 21.6 % and the stability of the sludge increased by 94.2 % on the in-situ formation of LDHs, which mainly attributed to 55.06 % oxidation of As(III) and co-precipitation of As with Zn and Fe. Additionally, a possible in-situ formation pathway for ZnFe-As-LDHs was illustrated. At the beginning of the process, non-crystalline ferric arsenate formed and then transformed to amorphous ferrihydrite as precursors, followed by the formation of LDHs. This work demonstrated that co-precipitating As with Zn and Fe in the wastewater to in-situ form LDHs exhibited excellent potential for removal and direct stabilization of As(III).

Abstract
Objective: To explore the clinicopathological characteristics and prognosis of patients with ovarian metastases from colorectal cancer. Methods: A total of 122 female patients with ovarian metastases from colorectal cancer underwent treatment in Cancer Hospital, Chinese Academy of Medical Sciences between 2010 and 2015 were recruited. The clinicopathological features, treatment details and survival data of these patients were retrospectively analyzed. Kaplan-Maier method was used for survival analysis, log rank test and Cox proportional hazards model were used for prognostic factor analysis. Results: The median overall survival (OS) was 19.7 months. The 1-year, 3-years and 5-years OS rates were 72.1%, 24.7% and 9.9%, respectively. A total of 99 (81.1%) patients underwent oophorectomy. The median OS of patients who underwent oophorectomy was 21.9 months, significantly longer than 10.3 months of patients without oophorectomy (P<0.01). Ovary as the only site of metastasis, primary tumor resection, and oophorectomy were associated with improved survival (all P<0.01). Primary tumor resection and oophorectomy were independent prognostic factors for OS (both P<0.01). Conclusion: Patients with ovarian metastases from colorectal cancer might acquire a survival benefit from surgical resection of the primary tumor and ovaries.

Abstract
BACKGROUND AND PURPOSE Melkersson-Rosenthal syndrome (MRS) is a rare neuro-mucocutaneous disease. In addition to the traditional clinical triad, there is also a diversity of clinical signs, and it may be related to other systemic diseases. METHODS In the present study, we report a case of MRS with endocrine disorders that exhibits extraordinary therapeutic efficiency by using hydroxychloroquine (HCQ), explore whether there is an internal connection between MRS and endocrine disorders, and discuss the mechanism of the therapeutic efficiency of using HCQ. The hypothesis proposed for the first time is that MRS may essentially be a systemic granulomatous disease. RESULTS The physical examination revealed orofacial swelling and fissured tongue. The histopathologic examination showed epithelioid granulomas. Combined with the other examination, this case was diagnosed as incomplete MRS. HCQ and local drugs were introduced. The patient achieved clinical recovery and psychological cure by the 18-week follow-up, and the 1-year follow-up found no reactivation of MRS. Moreover, the levels of cortisol and adrenocorticotropic were within normal ranges. CONCLUSIONS After the drug therapy was targeted at granuloma, not only did all of the symptoms related to MRS disappear, but the endocrine system also returned to normal. It is speculated that the endocrine disorder in this patient may be related to MRS. We further propose the first-time hypothesis that MRS may essentially be a systemic granulomatous disease. It provides a new medication method with high-level efficiency.

Abstract
Objective: To investigate the feasibility and safety of minimally invasive radical prostatectomy for prostate cancer patients without preoperative prostate biopsy in the new era of the continuous development of comprehensive new imaging diagnostic mode and minimally invasive surgery technology. Methods: From August 2018 to October 2019, 17 patients with prostate cancer were enrolled in this study in the Cancer Hospital, Chinese Academy of Medical Sciences. All patients were highly suspected of prostate cancer by PSMA-PET/CT-based imaging diagnostic techniques and underwent 3D laparoscopic radical prostatectomy without prostate biopsy. The perioperative data, postoperative pathology, postoperative complications and follow-up results were recorded and analyzed. Results: The average age of 17 patients with prostate cancer was (65±7) years. The body mass index (BMI) average was (24.4±3.0) kg/m(2). The American Society of Anesthesiologists (ASA) score was 1 (1-2) and the Charlson comorbidity index (CCI) score was 1 (0-4). The preoperative value of PSA was (19±11) μg/L. The PSMA PET/CT showed abnormally high expression foci and the great possibility of prostate cancer for all the 17 patients. Prostate puncture biopsy: the results of prostate biopsy were negative in 3 cases. The digital rectal examination found that the prostate volume was Ⅰ or Ⅱ degree large, 10 cases touched hard and the nodule was touched in two cases. Three patients had undergone a previous prostate biopsy, but prostate cancer was not found. All the 17 operations were successfully performed without conversion to open surgery. The surgery time was (85±21) (range from 45 to 120) min, the estimated blood loss was (25±18) (range from5 to 100) ml, the time of intake of liquid diet was (14.3±4.4) h, the intestinal recovery time was (23±10) h, the postoperative activity time was (22±7) h, the drainage duration was (3.7±0.8) d, the postoperative hospital stay was (4.9±1.2) days, and the catheter removal time was (7.4±1.5) days. In the early postoperative period (within 30 days after surgery), no obvious complications occurred. The postoperative final pathology confirmed that all the 17 specimens were prostate cancer. After a median follow-up of 6.5 months, the patient's urinary control rate reached 81.3% at postoperative 1 month, 92.3% at postoperative 3 months after surgery, and the urinary control rate reached 100% at postoperative 6 months. Postoperative PSA value was (0.08±0.08) μg/L, significantly lower than preoperative PSA level (P<0.001). There was significant difference between the preoperative and postoperative QOL (Quality of life) score (57±5 and 47±5 respectively, P<0.001) which indicated that the patients' postoperative quality of life was greatly improved. Conclusions: It is safe and feasible to perform minimally invasive radical prostatectomy without preoperative prostate biopsy for patients with highly suspected prostate cancer by comprehensive diagnostic mode based on modern new imaging technology.

Abstract
Objective: To assess the treatment and prognosis of vulvar melanoma. Methods: A total of 59 cases of primary vulvar melanoma admitted to Cancer Hospital of Peking Union Medical College, Chinese Academy of Medical Sciences from January 1st, 1981 to November 30th, 2019 were collected. The clinical characteristics, treatment, survival and prognostic factors of vulvar melanoma were analyzed retrospectively. The end date of follow-up was January 15th, 2020.The median follow-up time was 26.0 months (range:2-198 months). Results: (1) Clinical characteristics: the median age of 59 patients with vulvar melanoma was 56 years old (range:18-83 years old). According to the American Joint Committee on Cancer stage manual, there were 18, 7, 26 and 8 cases of stage Ⅰ, Ⅱ, Ⅲ and Ⅳ respectively. The lesion of 38 cases was single and the other 21 cases were multiple. The largest diameter of the tumor ranged from 0.3 to 17.0 cm.The surface of the lesion was ulcerated in 17 cases. (2) Treatment: a total of 59 cases with vulvar melanoma, 56 patients received surgery, 36 cases of them received radical resection of vulva and 20 received local extended resection of vulvar tumor due to unilateral vulva lesion. Three patients did not receive surgery,one received chemotherapy combined with interferon, one received interferon, and one received radiotherapy. Lymph node management: among the 56 patients treated by surgery, 37 patients received inguinal lymphadenectomy, 24 (65%, 24/37) of whom were confirmed with inguinal lymph node metastasis by postoperative pathological examination. Inguinal lymph nodes enlargement were not found in 19 cases by preoperative imaging and clinical examination. In these 19 patients, three patients received inguinal lymph node biopsy, among them, one (1/3) patient was confirmed with inguinal lymph node metastasis by postoperative pathological examination, and the remaining 16 patients did not receive inguinal lymph node surgery. Postoperative adjuvant treatment: among the 56 patients who received surgery, 31 received adjuvant chemotherapy,one received adjuvant radiotherapy, four received interferon therapy, 17 received combination therapy including chemotherapy, and three did not receive postoperative adjuvant therapy. (3) Survival:during the follow-up period, the median survival time of 59 patients with vulvar melanoma was 30.0 months (range:2.0-198.0 months). The 3-year survival rate was 42.5%, and the 5-year survival rate was 23.8%. The median survival time of stage Ⅰ, Ⅱ, Ⅲ and Ⅳ were 72.0, 45.0, 24.0 and 23.0 months, respectively. The difference among stage Ⅰ, Ⅱ and stage Ⅲ, Ⅳ were statistically significant (P<0.01). The median survival time of patients undergoing radical resection of the vulva (35.0 months) and local enlarged tumor resection (29.0 months) were significantly longer than that of patients without surgery (9.0 months, P<0.01). The median survival time of the patients who underwent inguinal lymphadenectomy, lymph node biopsy and those who did not undergo surgery were 35.0, 32.0 and 30.0 months, respectively. There were no significant differences among the 3 groups (P>0.05). The median survival time of postoperative adjuvant chemotherapy patients (49.0 months) were significantly longer than that of postoperative adjuvant radiotherapy, interferon,and combination therapy including chemotherapy (9.0, 14.0 and 26.0 months, respectively, all P<0.01). (4) Prognostic factors: the univariate analysis showed that stage, vulvar operation and postoperative adjuvant treatment were the risk factors affecting the prognosis of patients with vulvar melanoma (P<0.01). Multivariate analysis revealed that stage alone was an independent risk factor affecting the prognosis of patients with vulvar melanoma (P<0.01). Conclusions: The prognosis of patients with vulvar melanoma is poor, and stage is an independent prognostic factor.Surgery combined with postoperative adjuvant chemotherapy may achieve relatively good results.

Abstract
Objective: To explore the application of Endo-GIA stapler in laparoscopic radical cystectomy, especially in the treatment of lateral bladder ligament, and to evaluate its clinical feasibility and practicability. Methods: A retrospective analysis of clinical data about 38 cases of laparoscopic radical cystectomy (LRC) treated in the Department of Urology, Chaoyang Hospital of Beijing and Cancer Hospital, Chinese Academy of Medical Sciences from July 2017 to June 2019 were conducted. The patients were divided into Endo-GIA stopler group(18 cases) and non-Endo-GIA stopler group (20 cases) according to whether Endo-GIA stapler were used. The basic clinical data, operation time of bladder lateral ligament, operation time of bladder lateral wall, operation time of bladder resection, amount of bleeding during operation, pathological data after operation and related indicators of recovery after operation were compared between the two groups. Results: All 38 patients underwent radical cystectomy (RC) successfully under 3-D laparoscopy without conversion to open surgery. The operation time of bladder lateral ligament in Endo-GIA stapler group was significantly shorter than that in non-Endo-GIA stapler group [(3.25±0.75) min vs (9.20±2.95) min, P=0.042]; the operation time of bladder lateral wall in Endo-GIA stapler group was significantly shorter than that in non-Endo-GIA stapler group [(8.06±1.66) min vs (14.30±3.37) min, P=0.016]. The operation time of cystectomy in the Endo-GIA stapler group was significantly shorter than that in the non-Endo-GIA stapler group [(47.06±4.70) min vs (61.60±14.91) min,P=0.003]. The amount of bleeding in the Endo-GIA stapler group was significantly shorter than that in the non-Endo-GIA stapler group [(37.77±21.30) ml vs (114.50±39.80) ml, P=0.015]. The time of drainage tube removal in Endo-GIA group was significantly shorter than that in the non-Endo-GIA group [(5.83±1.54) d vs (7.30±3.00) d, P=0.002]. The length of post-hospitalization in Endo-GIA group was significantly shorter than that in the non-Endo-GIA group [(7.67±1.78) d vs (9.60±3.25) d,P=0.036]. However, there was no significant difference in other basic clinical data, post-operative pathology and post-operative recovery related indicators. Conclusions: Laparoscopic radical cystectomy using Endo-GIA stapler device is safe and feasible. It is easy to operate, shorten the operation time significantly, and reduce the amount of bleeding. To a certain extent, it is conducive to the recovery of patients after operation to some extent, and worthy of clinical application.

Abstract
BACKGROUND Despite their high accuracy to recognize oral potentially malignant disorders (OPMDs) with cancer risk, non-invasive oral assays are poor in discerning whether the risk is high or low. However, it is critical to identify the risk levels, since high-risk patients need active intervention, while low-risk ones simply need to be follow-up. This study aimed at developing a personalized computational model to predict cancer risk level of OPMDs and explore its potential web application in OPMDs screening. METHODS Each enrolled patient was subjected to the following procedure: personal information collection, non-invasive oral examination, oral tissue biopsy and histopathological analysis, treatment, and follow-up. Patients were randomly divided into a training set (N = 159) and a test set (N = 107). Random forest was used to establish classification models. A baseline model (model-B) and a personalized model (model-P) were created. The former used the non-invasive scores only, while the latter was incremented with appropriate personal features. RESULTS We compared the respective performance of cancer risk level prediction by model-B, model-P, and clinical experts. Our data suggested that all three have a similar level of specificity around 90%. In contrast, the sensitivity of model-P is beyond 80% and superior to the other two. The improvement of sensitivity by model-P reduced the misclassification of high-risk patients as low-risk ones. We deployed model-P in web.opmd-risk.com, which can be freely and conveniently accessed. CONCLUSION We have proposed a novel machine-learning model for precise and cost-effective OPMDs screening, which integrates clinical examinations, machine learning, and information technology.

Abstract
Objective: To explore the effects and postoperative prognostic factors in cervical cancer patients received neoadjuvant chemotherapy combined with surgery and post-operative adjuvant therapy. Methods: A total of 177 patients with cervical cancer at International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ b2, Ⅱ a2 who underwent neoadjuvant chemotherapy (NACT) followed by surgery with and without adjuvant therapy in Cancer Hospital, Chinese Academy of Medical Sciences were included. Univariate and multivariate analyses of 5-year overall survival (OS) rate and 5-year disease-free survival (DFS) rate were performed. Results: Of 177 patients, 133 (75.1%) had stage Ⅰb2 and 44 (24.9%) had Ⅱa2 cancers. After NACT, overall response rate was 63.3% (112/177) including 12 cases of complete response (CR), 100 of partial response (PR) and no progressive disease (PD) case. At a median follow-up of 59.2 months, the 5-year DFS rate was 73.6% and the 5-year OS rate was 86.8%. Univariate analysis revealed that lymph node metastasis, deep stromal invasion and tumor size after NACT significantly affected 5-year DFS rate (P<0.05). Lymph node metastasis, deep stromal invasion and tumor size after NACT significantly affected 5-year OS rate (P<0.05). The multivariate analysis showed that, stromal invasion (outer 1/3 or outer 1/2) was independent risk factor of 5-year DFS rate (P<0.05), and 5-year OS rate was significantly affected by tumor size >3 cm after NACT (P<0.05). Conclusions: The effect of NACT in Ⅰ b2, Ⅱ a2 squamous carcinoma of the uterined cervix is confirmed. The independent risk factor for 5-year DFS rate in patients received NACT and hysterectomy is deep stromal invasion of the cervix. The presence of tumor size >3 cm after NACT adversely affect 5-year OS rate.

Abstract
Objective: To investigate the efficacy and side effect of paclitaxel liposome for neoadjuvant chemotherapy (NACT) in locally advanced cervical cancer. Methods: This study were included 265 cervical cancer patients staging Ⅰb2 and Ⅱa2 who underwent paclitaxel-platinum NACT followed by radical surgery from June 2008 to December 2016 in the Cancer Hospital, Peking Union Medical College, Chinese Academy of Medical Sciences. All patients were classified into two groups with 106 patients in paclitaxel liposome group and 159 patients in traditional paclitaxel group. The difference in clinicopathologic characteristics, efficacy and side effect were analyzed retrospectively between the two groups. Results: (1) Clinicopathologic characteristics: there were no significant difference in clinicopathologic characteristics between the two groups, including age, body mass index, clinical stage, pathological histology, cycles of NACT, combined platinum regimen, lymph-vascular space invasion, lymph node metastasis, deep stromal invasion, and postoperative adjuvant therapy (all P>0.05). (2) Efficacy: after NACT, the overall response occurred in 90 (15 complete response plus 75 partial response) of 106 cases in the paclitaxel liposome group versus 131 (21 complete response plus 110 partial response) of 159 cases in the traditional paclitaxel group without statistical significance (84.9% vs 82.4%; χ(2)=0.291, P=0.590). A total of 248 patients received surgery after NACT and were evaluable in survival. The 5-year recurrence-free survival (RFS) rate and 5-year overall survival (OS) rate of these patients was 85.1% and 88.2%. The 5-year RFS rate in the paclitaxel liposome group was 85.9% compared with 85.2% in the traditional paclitaxel group, while the corresponding 5-year OS rate was 88.5% and 88.7%, respectively. There was no statistically significant difference in efficacy between the two groups (P=0.968, P=0.797). (3) Side effect: the incidence of allergic reaction between the paclitaxel liposome group and the traditional paclitaxel group was 0 versus 1.9% (3/159) without statistical significance (P=0.277). But the incidence of neurotoxicity in the paclitaxel liposome group significantly decreased compared with the traditional paclitaxel group (6.6% vs 15.7%, P<0.05), as well as the incidence of alopecia (67.9% vs 79.2%, P<0.05) and myalgia (17.9% vs 28.9%, P<0.05). However, significant differences were not found in terms of hematological toxicity, gastrointestinal reaction, and hepatic function damage (P>0.05). Conclusion: In paclitaxel-platinum NACT of local advanced cervical cancer, paclitaxel liposome can achieve similar efficacy compared with traditional paclitaxel, but paclitaxel liposome is helpful in decreasing the toxicity of neurotoxicity, alopecia and myalgia.

Method: A total of 105 cases of cognitivenormal (CN), 48 aMCI and 50 mild AD patients were included between 2016 and 2018. All subjects undertook detailed neuropsychological tests and brain MRI/CT scan. Results: The total score of five learning trials in CN, aMCI and AD groups were 53.9±6.9, 34.6±8.3 and 23.7±6.2, respectively (P<0.001). The score of 20-min delay recallwere 12.5±1.6, 4.3±3.0 and 0.6±1.0, respectively (P<0.001) in three groups. The score of cued recall were 13.0±1.4, 7.0±2.4 and 2.6±2.0, respectively (P<0.001). The score of 20-min delay recall had the largest effect sizes between CN and aMCI groups (Cohen'd=3.8, 95%CI,3.3-4.4), and CN and mild AD groups (Cohen'd=8.1, 95%CI 7.1-9.1). Cued recall had the largest effect size between aMCI and mild AD groups (Cohen'd=2.04, 95%CI 1.5-2.5). The scores of learning total score, 20-min delay recall, cued recall and recognition had the strong relationships with the scores of mini-mental state examination (MMSE) and Montreal cognitive assessment (MoCA) , but obtaining moderate relationships with Boston naming test and trail making test (TMT) and weak relationships with digit span and figure copy. Age and education had no relationship with the main indices of this modified AVLT. Conclusions: The modified WHO/UCLA AVLT is still an age and education fair test to assess memory domain function. Qualitative analysis of AVLT profiles may be useful to differentiate the CN, aMCI and mild AD in Chinese sample.

Abstract
In order to improve the heavy metal wastewater treatment by avoiding formation of amorphous sludge phase, we develop a faster formation of high crystalline layered double hydroxide (LDH) sludge to remove Cu and Zn from wastewater by controlled double-jet precipitation (CDJP) without hydrothermal or heat aging post-treatment. A series of experimental procedures are conducted to determine the optimal parameters. Results show that the optimal adding rate, pH value, and stirring rate is 0.5 mL min-1, 9.0, and 500 rpm, respectively. The CuZnAl-LDH phase sludge is formed in a well-crystallized hexagonal platelet, which assembled into a flower-like architecture. Comparative studies show that the formation of amorphous LDH sludge in conventional precipitation (CP) could be divided roughly into two stages-from the mixed copper hydroxide, zinc hydroxide, and scarbroite to the mixed low crystallinity CuAl-LDH and ZnAl-LDH. However, in CDJP method, the high crystalline LDH sludge evolved from a new four-step evolution process that is the formation of an amorphous (quasi-)multinary metastable ternary CuZnAl-LDH phase, followed by the indiffusion of cations and substitution of anions to fabricate crystalline LDH, the integrated LDH hexagonal platelets assembled into a flower-like architecture by the screw dislocation growth mechanism, the coarsening growth of each ternary LDH platelet, respectively. Thereinto, the formation of (quasi-)multinary metastable LDH phase instead of metal hydroxide in initial stage would be an obvious advantage of the CDJP method compared to CP method due to the former skipping the sequential precipitation.

Abstract
Objective: To investigate the prevalence of high-risk HPV subtypes in different pathological types of cervical cancer, and analyze the attribution of carcinogenic HPV subtypes in different pathological types. Methods: A total of 1 541 patients with cervical cancer were treated between February 2009 and October 2016 in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. The median age at diagnosis was 49 years (ranged 20-82 years old). The numbers of patients with cervical cancer from North China, Northeast China, East China, Central China and other regions (including Northwest, Southwest and South China) were 961, 244, 175, 87 and 74 cases, respectively. Pathological types: 1 337 cases of squamous cell carcinoma (SCC), 87 usual adenocarcinoma (ADC), 23 adenosquamous carcinoma (ASC), 20 mucinous carcinoma (MC), 19 clear cell carcinoma (CCC), 12 endometrioid carcinoma (EC), 25 neuroendocrine carcinoma (NEC), 9 serous carcinoma (SC), 5 villous adenocarcinoma (VADC) and 4 minimal deviation adenocarcinoma (MDAC). The prevalence of high-risk HPV in different regions, age groups at diagnosis and pathological types in cervical cancer were analyzed. The attribution of 13 high-risk HPV subtypes in different pathological types of cervical cancer based on proportional attribution method, and the attribution of high-risk HPV subtypes prevented by 9-valent HPV vaccine in SCC and ADC were calculated. Results: (1) The prevalence of high-risk HPV in 1 541 patients with cervical cancer was 86.6% (1 335/1 541). The multiple high-risk HPV infection rate in patients with SCC ≥60 years old (23.0%, 37/161) was significantly higher than those in patients aged 45-59 years old and ≤44 years old [11.4% (85/747) vs 11.7% (50/429), P<0.01], and the high-risk HPV infection rates of patients with cervical cancer in North China, Northeast China, East China, Central China and other regions were respectively 86.8% (834/961), 87.7% (214/244), 83.4% (146/175), 83.9% (73/87) and 91.9% (68/74). SCC (86.8%, 1 337/1 541) and ADC (5.6%, 87/1 541) were the most common pathological types in cervical cancer. The high-risk HPV prevalence of SCC, ADC, ASC, MC, NEC and VADC were 90.1% (1 205/1 337), 74.7% (65/87), 87.0% (20/23), 65.0% (13/20), 72.0% (18/25) and 5/5 respectively. The high-risk HPV infection rates of SC, EC, CCC and MDAC were 4/9, 3/12, 2/19 and 0/4 respectively. (2) According to proportional attribution, HPV 16 (69.5%), HPV 18 (5.6%), HPV 58 (2.2%), HPV 31 (1.9%), HPV 52 (1.4%) and HPV 33 (1.3%) were the six common high-risk HPV subtypes in SCC. While, HPV 18 (44.1%), HPV 16 (20.5%), HPV 52 (2.3%), HPV 58 (1.2%) and HPV 51 (1.2%) were the main carcinogenic subtypes in ADC. The main carcinogenic high-risk HPV subtypes of ASC, NEC and MC were HPV 18 and HPV 16. The total attribution of HPV 16, 18, 31, 33, 45, 52 and 58 prevented by 9-valent HPV vaccine in SCC and ADC were 82.6% and 68.1% respectively; the attribution of HPV 45 in SCC and ADC were only 0.8% and 0. Conclusions: SCC and ADC are the main pathological types in cervical cancer. SCC, ADC, ASC, MC, NEC and VADC are closely related to high-risk HPV infection. HPV 16 is the main carcinogenic genotypes of SCC. HPV 18 maybe play an important role in the pathogenesis of ADC.

Abstract
Objective: To evaluate the significance of different clinicopathologic features on prognosis of patients with squamous cell carcinoma of vulva. Methods: We retrospectively analyzed the prognostic relevance of different clinicopathological variables of 201 patients with squamous cell carcinoma of vulva treated in Cancer Hospital, Chinese Academy of Medical Sciences. The data including age, initial symptoms, stage, location, tumor size, histological grade, number and size of metastatic lymph nodes, treatment mode, and presence of leukoplakia vulva was used to evaluate the prognosis of vulvar squamous cell carcinoma. Results: The median age of onset was 62.0 years old, with 74 patients in stage Ⅰ, 27 in stage Ⅱ, 55 in stage Ⅲ and 9 in stage Ⅳ. The median progression-free survival was 90.0 months. The 5-year progression-free survival rate of the total patients was 55.5%, while the 10-year progression-free survival rate was 48.5%. Univariate analysis showed statistically significant prognostic parameters included clinical stage, number of metastatic lymph nodes, tumor size and treatment mode (all P<0.001). Multivariate analysis showed that number of metastatic lymph nodes (P<0.05) was an independent prognostic factor for progression-free survival. Conclusion: The study illustrates that number of metastatic lymph nodes represents important independent factor for progression-free survival of patients with vulvar squamous cell carcinoma.

Abstract
Objectives: To analyze the cardiac T2* value, liver iron concentration (LIC) , and related laboratory parameters in myelodysplastic syndrome (MDS) with iron overload and evaluate the changes of organ functions after iron chelation therapy. To explore the value of magnetic resonance imaging (MRI) T2* in making early diagnosis and assessing organs iron overload. Methods: Retrospective investigation was used to observe the cardiac T2* value, LIC, iron metabolism parameters and related laboratory parameters of 85 MDS patients from Nov 2014 to Jan 2018. Among them, 7 MDS patients with Low/Int-1 have received iron chelation therapy for 6 months during two MRI examinations. The above parameters were collected before and after iron chelation therapy for comparison. Results: Correlations were found between heart T2* value and age (rs=-0.290, P=0.007) and left ventricular ejection fraction (LVEF) (rs=0.265, P=0.009) . There was a significant negative correlation between heart T2* value and blood transfusion units (rs=-0.701, P<0.001) . There was a significant positive correlation between LIC and serum ferritin (SF) (rs=0.577, P<0.001) . There was also a correlation between LIC and ALT (rs=0.268, P=0.014) and blood transfusion units (rs=0.244, P=0.034) . There was no correlation between heart T2* and pro-BNP, SF (all P>0.05) , and no correlation between LIC and age (P>0.05) . The increase of heart T2* between the normal and abnormal groups was statistically significant (P=0.005) , but the iron overload ratio of the heart T2*<20 ms was not significant between the two groups. There was statistical significance in the proportion of severe liver iron overload (LIC>15 mg/g DW) (P=0.045) . After iron chelation therapy, the values of SF, transferrin saturation, ALT, AST, pro-BNP and LIC of 7 patients were decreased compared with values before iron chelation therapy, and the peripheral blood cell level was increased. However, the changes of LVEF and T2* values after iron chelation were not obvious. Conclusion: MRI T2* may be a predictor of iron overload in patients with MDS in early stage, and may be more valuable compare with LVEF, SF and other laboratory indicators. The safety and repeatability of MRI cardiac T2* examination are recognized, and it can be used as an ideal detection for patients with iron overload.

Abstract
Objective: To analyze the prognosis of Ⅰb2 and Ⅱa2 cervical squamous cancer without high risk factors treated with neo-adjuvant chemotherapy (NACT) and radical hysterectomy. Methods: This retrospective study included patients with International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ b2 and Ⅱ a2 cervical squamous cancer without high risk factors who underwent platinum-based NACT followed by radical surgery from January 2008 to January 2015. The responses of NACT were observed and compared in their effect on postoperative pathologic risk factors. Kaplan-Meier method and Cox regression analysis were performed to analyze survival status. Results: This study was recruited 282 patients with the average age of (44.4±6.7) years old. After NACT, 42 patients achieved complete response [CR, 14.9% (42/282) ], while 138 patients achieved partial response [PR, 48.9% (138/282) ] and 102 stable disease [SD, 36.2% (102/282) ]. The rate of pathologic diameter ≥4 cm, deep stromal invasion (DSI) positive and lymph-vascular space invasion (LVSI) positive rate decreased significantly in CR and PR group compared with SD group (P<0.05) . The number of postoperative risk factors in CR, PR and SD groups varied significantly (χ(2)=64.869, P=0.000) . Besides, the rate of multiple intermediate risk factors was respectively 0 vs 13.8% vs 45.1% (χ(2)=7.107, P=0.008) . The disease relapsed in 23 patients, and 12 died. On the whole series, 5-year overall survival rate was 91.7%, and 5-year recurrence-free survival rate was 88.9%. The rate of recurrence (P=0.002) and mortality (P=0.036) were higher in LVSI positive patients compared with LVSI negative. And the rate of recurrence was higher in patients with multiple intermediate risk factors, compared with no or one intermediate risk factors (P=0.002) . Univariate analysis revealed that LVSI positive and multiple intermediate risk factors were the factors predicted recurrence and mortality (P<0.05) , and no significance in age, stage, tumor grade, tumor diameter before or after NACT, response to NACT, or DSI positive factors (all P>0.05) . The multivariate analysis showed that, the factor of primary tumor diameter ≥6 cm (P=0.022) and multiple intermediate risk factors (P=0.001) were independent prognostic variables for recurrent-free survival. Besides, multiple intermediate risk factors was independent prognostic variable for overall survival (P=0.034) . After surgery, 107 patients did not receive adjuvant therapy, while 175 patients received adjuvant therapy with 26 radiotherapy, 46 chemotherapy and 103 concurrent radiochemotherapy. On survival analysis of postoperative adjuvant treatment, 5-year recurrence-free survival rate of radiotherapy group was significantly lower in patients with the factor of SD response to NACT (P=0.011) and multiple intermediate risk factors (P=0.008) , while overall no significance in overall survival rate (P>0.05) . Conclusions: NACT may be play beneficial role in relieving the status of intermediate risk factors for stage Ⅰ b2 and Ⅱ a2 cervical squamous cancer without high risk factors. The status of multiple intermediate risk factors is independent prognostic factors for recurrence and mortality. For patients with multiple intermediate risk factors, postoperative adjuvant chemotherapy or concurrent radiochemotherapy might be the better choice to prevent relapse.

Abstract
Objective: To study the efficacy of surgery for recurrent cervical cancer and the influencing factors on prognosis. Methods: To retrospectively analyze the clinical data of 45 patients with recurrent cervical cancer undergoing surgical treatment in our hospital from January 1980 to October 2015, and study their clinical features and prognosis. Results: The Recurrence Free Interval (RFI) of these 45 patients was 3~120 months, and their median RFI was 15 months. Of the 45 cases, 21 recurred inside the radiotherapy field, including 18 with central recurrence and 3 with non-central recurrence; and 24 recurred outside the radiotherapy field, including 16 with pelvic recurrence who did not receive radiotherapy and 8 with distant recurrence. The overall survival time after recurrence of these 45 cases was (39.1±1.0) months, and their 2-year and 5-year survival rates were 55.6% and 22.2%, respectively. The univariate analysis showed that clinical stage, RFI, recurrent site, and initial treatment method affected the survival rate of the patients with recurrent cervical cancer (P<0.05), while the multivariate analysis revealed that recurrent site was an independent prognostic factor for recurrent cervical cancer (P=0.047). Conclusions: Appropriate surgery should be chosen for recurrent cervical cancer according to initial treatment and recurrent site. For patients with central recurrence inside their radiotherapy field, surgery is an effective treatment. Surgery is also suitable for patients without previous radiotherapy and with isolated recurrence, and adjuvant radiotherapy and chemotherapy can improve their survival.

Abstract
We aimed to investigate the influence of regulatory T cells including CD4+CD25+, CD8+CD28- and hepatitis B virus (HBV) genotype on sustained virological response and tolerance of nucleoside drugs. One hundred and thirty-seven patients were enrolled. Lamivudine was administered to 84 patients. Entecavir was administered to the other 53 patients. Before treatment, biochemical tests, HBV DNA load, HBV serum level, HBV genotype, PB CD3+, CD4+, CD8+, CD4+CD25+/CD3+, and CD8+CD28-/CD3+ frequencies were measured. Based on HBV DNA loads after 4 weeks of therapy, patients were divided into response group and suboptimal response group. The lamivudine group received treatment continuously, and then patients were categorized into non-resistance group and resistance group. Compared with the suboptimal response and resistance groups for lamivudine, CD4+CD25+/CD3+ levels were higher in the response and non-resistance groups (t=4.372, P=0.046; t=7.262, P=0.017). In the non-resistance group, CD8+CD28-/CD3+ frequency was lower than in the resistance group (t=5.527, P=0.037). Virus load and hepatitis B E antigen (HBeAg)-positive rate were significantly lower than in the response and resistance group (t=2.164, P=0.038; X2=4.239, P=0.040; t=2.015, P=0.044; X2=16.2, P=0.000). Incidence of drug resistance was high in patients with virogene type C. For the virological response to entecavir, CD8+CD28-/CD3+ level was significantly lower than that of the suboptimal response group (t=6.283, P=0.036). Response and suboptimal response groups were compared in CD3+, CD4+, CD8+, CD4+CD25+/CD3+ and virus genotype, and differences were not statistically significant (P>0.05). Baseline regulatory T cells including CD4+CD25+/CD3+ and CD8+CD28-/CD3+ frequencies have a relationship with the incidence of rapid virological response and the resistance to nucleoside drugs. Patients with HBV genotype C receiving lamivudine more often underwent drug resistance. Antiviral efficacy and the resistance to lamivudine were closely correlated with baseline factors; the same cannot be found for entecavir.

Abstract
Objective: To summarize the initial experiences of applying sacral neuromodulation (SNM) for refractory interstitial cystitis/pelvic pain syndrome (IC/PPS). Methods: From January 2013 to August 2016, 26 patients with refractory IC/PPS (including 5 males and 21 females) treated with SNM were recruited in Beijing Chaoyang Hospital and Hebei Yanda Hospital in this retrospective study. The data before operation, after implantation of stage Ⅰ tined lead, and during short-term follow-up after implantation of stage Ⅱ implanted pulse generator (IPG) were compared in order to observe the improvement of relevant symptoms, and to summarize the effectiveness and safety of SNM for IC/PPS. Results: All the 26 patients received stage Ⅰ tined lead implantation under local anesthesia, of whom 7 patients finally had the tined lead removed under local anesthesia because of poor testing effects. And 19 patients chose embedding of IPG at the end of stageⅠ, with the conversion rate from stage Ⅰto stage Ⅱ being 73.1%. The mean follow-up time after stage Ⅱ was 12.1 months. The data at the end of follow-up compared with those before treatment were: voiding frequency in 24 hours 24.3±9.6 vs 13.5±5.7, nocturia 4.6±2.2 vs 2.7±1.5, average voiding amount (109.4 ±45.3)vs(172.6±61.6) ml, O'leary-sant scale score 26.0±3.1 vs 17.0±3.8, quality of life (QOL) score 5.7±0.4 vs 3.3±1.3, sex rating 5.4±1.4 vs 2.9±1.6, and Numeric Pain Intensity Scale 8.4±1.7 vs 3.9±1.2 (all P<0.05). During the follow-up period for the 19 patients, 11 showed symptoms relieve without recurrence, 5 patients had slightly symptoms recurrence and 3 patients had severe recurrence of pelvic pain and frequent urination. About 42.1%(8/19) patients received reprogramming, the average reprogramming rate being 1.73/person. And 84.2% (16/19) patients had symptoms improvement greater than 50% after stage Ⅱ IPG implantation. Conclusions: SNM is an effective, safe and minimally invasive procedure for refractory IC/PPS. IC/PPS is a good indication for SNM with a high conversion rate from stage Ⅰ to stage Ⅱ. Patients should be followed up regularly after operation, and reprogramming should be arranged according to the degree of symptom improvement.

Abstract
This trial was conducted to study the effect of full-fat rice bran inclusion in diets on growth performance, carcass and meat quality and fatty acid composition in Sichuan goose. A total of 204 Sichuan white male geese (28-d-old, 984 ± 15 g) were used in the 42-d assay. Full-fat rice bran inclusion in diets was 0%, 6%, 12% and 18%, respectively. On d 70, two geese from each pen were randomly selected and killed for measuring the carcass and meat quality and the meat fatty acid composition. The results showed that full-fat rice bran inclusion had no effect on average daily gain during 28-56 d, but rice bran inclusion at 18% increased average daily gain during 57-70 d. In addition, the full-fat rice bran supplementation decreased the subcutaneous fat yield, and the inclusion of full-fat rice bran in amounts of 12% and 18% decreased the half-eviscerated carcass yield, eviscerated carcass yield and crude fat content in goose meat. Moreover, full-fat rice bran supplementation had no effect on the content of total saturated fatty acid (SFA), but decreased the content of total monounsaturated fatty acid (MUFA). The inclusion of full-fat rice bran in amounts of 12-18% increased the content of total polyunsaturated fatty acid (PUFA) and total n-6 in goose meat and in the amount of 18% increased n-3 fatty acids content in goose meat. The results indicated that the rice bran inclusion had a positive effect in geese by stimulating growth performance and improving meat quality and fatty acid composition of goose meat.

Abstract
OBJECTIVE To decipher the cognitive and linguistic feature of logopenic variant primary progressive aphasia (lv-PPA) and nonfluent variant primary progressive aphasia (nfv-PPA) and to explore the extent to which cognitive and language impairment contribute to the dysfunction of activity of daily living(ADL). METHODS Seven lv-PPA and five nfv-PPA were enrolled in memory clinic of Xuanwu Hospital, Capital Medical University from January 2015 to January 2016 accordig to the international consensus criteria for PPA and its three subtypes. 20 age-matched normal controls (NC) were included. Both the patients and the NC completed a battery of neuropsychological test, lingusitic test and brain magnetic resonance imaging. All the patients conducted (11)C Pittsburgh compound B (PiB) PET imaging. RESULT Lv-PPA patients were characterized by deficits in lexical retrieval and long sentenses repetition, while nfv-PPA were with motor speech apraxia and phonetic distortion. Compared with nfv-PPA, lv-PPA patient displayed more severe cognitive deficit with younger onset of age (56±5 vs 61±5, P<0.05) , rapid decline of MMSE score within 1.5 years and pariental cortex dysfunctions such as ideomotor praxis, Gerstmann syndrome and contructional apraxia. Correlation analysis indicated that there was more significant association between pariental cortex dysfunction and ADL/mini-mental state examination(MMSE) than that of language deficit(r=-0.868, r=-0.922; r=0.312, r=-0.257). All seven lv-PPA were PiB-PET positive and five nfv-PPA were negative. CONCLUSION This study enriched the chinical and linguistic characterization of lv-PPA and nfv-PPA, which has implication for diagnosis, disease management and treatment for clinicians.

Abstract
Our objective was to explore the expression and clinical significance of Kelch-like epichlorohydrin-associated protein 1 (Keap1) in breast cancer tissue. Eighty-one breast cancer patients having undergone surgical treatment in our hospital between March 2002 and December 2008 were enrolled in this study. Normal tissue adjacent to tumors was used for the control samples. Diagnoses for all patients were confirmed by postoperative pathological examination. Immunohistochemical assays were used to measure the expression of Keap1 protein in breast cancer tissue and adjacent normal tissue, and its clinical significance was explored. We observed that 24.6% breast cancer tissue samples were positive for Keap1, a significantly lower proportion than that seen with adjacent normal tissue specimens (80.2%; P < 0.05). The presence of Keap1 expression did not correlate with age, tumor size, pathological classification, or degree of differentiation. However, it was found to be significantly associated with tumor-node-metastasis stage and the presence of lymphatic metastasis. Kaplan-Meier survival analysis showed a remarkably higher five-year survival rate among patients with positive Keap1 expression than in those lacking detectable levels of the protein (P = 0.032). Keap1 expression is significantly decreased in breast cancer tissue; therefore, the early detection of its expression might have great significance in determining prognosis for breast cancer patients.

Abstract
OBJECTIVE To investigate the clinical features, treatments and prognostic factors of rhabdomyosarcoma(RMS)in the female genital tract. METHODS A retrospective analysis was performed on 13 cases of RMS in the female genital tract. Clinical characteristics, treatments and prognosis were compared and analyzed statistically. RESULTS The median age was 21.0 years(range, 6 to 54 years). There were 6 cases vaginal RMS and 7 cases cervical RMS, included 11 cases of embryonal RMS(ERMS)and 2 cases of alveolar RMS(ARMS). According to the Federation International of Gynecology and Obstetrics(FIGO)staging system, there were 6 cases of stage Ⅰ , 3 cases of stage Ⅱ, 1 case of stage Ⅲ and 3 cases of stage Ⅳ, the median survival time were respectively 112.5, 153.0, 9.0 and 3.5 months. According to the Intergroup Rhabdomyosarcom Study Group(IRSG)staging system, there were 10 cases of stage Ⅰ and 3 cases of the stage Ⅳ, and their median survival time were respectively 112.5 and 3.5 months. Nine patients received surgery and the median survival time was 108.0 months(range, 9 to 228 months), 6 of them received chemotherapy after surgery and the median survival time was 152.0 months(range, 9 to 228 months), the other 3 cases did not receive any therapy after surgery and the median survival time was 25.0 months(range, 9 to 108 months). Four patients did not receive surgery and the median survival time was 6.3 months(range, 1 to 117 months). There were 2 cases received combined treatment included radiotherapy and the survival time were respectively 4 and 198 months. There were 8 cases who was survival without disease and 5 cases died of cancer. The median survival time in 13 patients was 25.0 months(range, 1 to 228 months)and the 5-year overall survival rate was 58.6%. CONCLUSIONS The prognosis of early stage of RMS in the female genital tract is good. While, the prognosis of advanced stage is poor. The standard treatment strategy is combination of surgery and chemotherapy, whether radiotherapy could improve the prognosis still need further study.

Abstract
The aim of this study is to investigate the role of the purinergic receptor P2X3 in the peripheral and central nervous systems during acupuncture treatment for the visceral pain of irritable bowel syndrome (IBS). A total of 24 8-day-old Sprague-Dawley (SD) neonatal male rats (SPF grade) were stimulated using colorectal distention (CRD) when the rats were awake. The modeling lasted for 2 weeks with one stimulation per day. After 6 weeks, the rats were randomly divided into three groups of eight each: (1) the normal group (NG, n = 8); (2) the model group (MG, n = 8); and (3) the model + electroacupuncture group (EA, n = 8) that received electroacupuncture at a needling depth of 5 mm at the Shangjuxu (ST37, bilateral) and Tianshu (ST25, bilateral) acupoints. The parameters of the Han's acupoint nerve stimulator (HANS) were as follows: sparse-dense wave with a frequency of 2/100 Hz, current of 2 mA, 20 min/stimulation, and one stimulation per day; the treatment was provided for seven consecutive days. At the sixth week after the treatment, the abdominal withdrawal reflex (AWR) score was determined; immunofluorescence and immunohistochemistry were used to measure the expression of the P2X3 receptor in myenteric plexus neurons, prefrontal cortex, and anterior cingulate cortex; and, a real-time PCR assay was performed to measure the expression of P2X3 messenger RNA (mRNA) in the dorsal root ganglion (DRG) and spinal cord. After stimulation with CRD, the expression levels of the P2X3 receptor in the inter-colonic myenteric plexus, DRG, spinal cord, prefrontal cortex, and anterior cingulate cortex were upregulated, and the sensitivity of the rats to IBS visceral pain was increased. Electroacupuncture (EA) could downregulate the expression of the P2X3 receptor and ease the sensitivity to visceral pain. The P2X3 receptor plays an important role in IBS visceral pain. The different levels of P2X3 in the peripheral enteric nervous system and central nervous system mediate the effects of the EA treatment of the visceral hyperalgesia of IBS.

Abstract
The complex interactions between cancer cells and their surrounding stromal microenvironment play important roles in tumor initiation and progression and represent viable targets for therapeutic intervention. Here, we propose a concept of common target perturbation (CTP). CTP acts simultaneously on the same target in both the tumor and its stroma that generates a bilateral disruption for potentially improved cancer therapy. To employ this concept, we designed a systems biology strategy by combining experiment and computation to identify potential common target. Through progressive cycles of identification, TGF-β receptor III (TβRIII) is found as an epithelial-mesenchymal common target in oral squamous cell carcinoma. Simultaneous perturbation of TβRIII in the oral cancerous epithelial cells and their adjacent carcinoma-associated fibroblasts effectively inhibits tumor growth in vivo, and shows superiority to the unilateral perturbation of TβRIII in either cell type alone. This study indicates the strong potential to identify therapeutic targets by considering cancer cells and their adjacent stroma simultaneously. The CTP concept combined with our common target discovery strategy provides a framework for future targeted cancer combinatorial therapies.

Abstract
Close homologue of L1 (CHL1) is a transmembrane cell adhesion molecule that is critical for brain development and for the maintenance of neural circuits in adults. Recent studies revealed that CHL1 has diverse roles and is involved in the regulation of recovery after spinal cord injury. CHL1 expression was downregulated in the cerebral cortex, hypothalamus, and brain stem after the induction of acute hypoxia (AH). In the current study, we sought to address the role of CHL1 in regulating homeostasis responses to hypoxia using CHL1-knockout (CHL1−/−) mice. We found that, compared with wild-type littermates, CHL1−/− mice showed a dramatically lower mortality rate and an augmented ventilatory response after they were subjected to AH. Immunofluorescence staining revealed that CHL1 was expressed in the carotid body (CB), the key oxygen sensor in rodents, and CHL1 expression level in the CB as assayed by western blot was decreased after hypoxic exposure. The number of glomus cells and the expression of tyrosine hydroxylase (a marker for glomus cells) in the CB of CHL1−/− mice appeared to be increased compared with CHL1+/+ mice. In addition, in the ex vivo CB preparation, hypoxia induced a significantly greater afferent nerve discharge in CHL1−/− mice compared with CHL1+/+ mice. Furthermore, the arterial blood pressure and plasma catecholamine levels of CHL1−/− mice were also significantly higher than those of CHL1+/+ mice. Our findings first demonstrate that CHL1 is a novel intrinsic factor that is involved in CB function and in the ventilatory response to AH.
