Abstract
Objective: To analyze 8 cases of paraquat lung transplantation in the world, and to explore the timing of lung transplantation and the factors affecting prognosis. Methods: An analysis of the clinical data of a paraquat poisoning lung transplant patient completed by The 12th People's Hospital of Guangzhou Medical University and The First People's Hospital affiliated to Guangzhou Medical University in August 2017 and literature review. Results: A 26 years old female patient was admitted to the hospital ingested 20% paraquat solution 20ml. On the 58th day of poisoning, she underwent double lung transplantation under general anesthesia. The operation was successful. Excised lungs show extensive lung fibrosis in both lungs, which was consistent with paraquat poisoning. Used tacrolimus and corticosteroids and mycophenolate antirejection, the patient discharged 46 days after surgery. 7 articles were retrieved through the search tool, and a total of 8 articles included this case were reported. Five patients who underwent lung transplantation within 1 month after poisoning all died, And 3 patients conducted lung transplantation for more than 1 month after poisoning survived; Pathogenic bacteria were isolated from the sputum in 3 of the 8 cases, all containing Pseudomonas, 2 of which died, and our case survived. Conclusion: Appropriate transplantation time window is very important for the prognosis of paraquat poisoning after lung transplantation. Active treatment of the sputum pathogens, improving the donor receptor matching, and exhausting the various means to remove the paraquat from the storage pool which may improve success rate of lung transplantation.

Abstract
Objective: To investigate the pathological features and clinical manifestation of pediatric nodal marginal zone lymphoma(NMZL). Methods: Histological morphology and immunophenotype of 7 cases of pediatric NMZL were retrospectively reviewed at Beijing Friendship Hospital Affiliated to Medical University between January 2008 to October 2018. Clonal rearrangement analysis was performed. Clinical information including patient follow-up data were analyzed. Results: All 7 patients were male with a median age of 15 years aged from 10 to 26 years. All patients presented with only lymph node enlargement without B symptoms, including cervical lymph node (5 cases), preauricular lymph node (1 case) and retroauricular lymph node (1 case). Histologically, all cases showed irregular large follicles on the edges with widened marginal areas and intervesicular areas, and lesional cells were uniform with progressive transformation of germinal center centers along with a small amount of intrinsic lymphoid tissue. All 7 cases showed diffuse CD20 positivity both follicle and interfollicular region along with 30%-40% positivity in the interfollicular region (pathological region). Markers of other B-cell lymphomas werenot expressed. All 7 cases were positive for immunoglobulin(Ig) gene rearrangement. None of the patients showed no recurrence up on after follow-up for an average of 13 months. Conclusions: Pediatric NMZL is a rare type of lymphoma that has a unique morphology and occurs almost exclusively in male children and young adults and often in head and neck lymph nodes. It has an excellent prognosis. Therefore, awareness of the disease with accurate diagnosis is important.

Abstract
Objective: To investigate the prevalence, demographic characteristics and social life function of mental disorders in the rural left behind elderly aged 60 years and older in Gansu. Methods: Between November 2017 and June 2018, a multi-stage stratified cluster sampling method was used to randomly select the rural left behind elderly aged 60 years and older in Gansu, and totally 6 000 elderly were enrolled. By using the extended general health questionnaire (GHQ-12) and the American Handbook for Diagnosis and Statistics of Mental Disorders (DSM-Ⅳ) Axis Ⅰ Disorders Formal Clinical Examination Patient Edition, all the included subjects were screened and diagnosed. Functional status was assessed by the Global Assessment Function scale (GAF). Statistical analysis of the prevalence of various mental illnesses, as well as the differences in the prevalence of different gender, marital status and age groups was performed. Results: Totally, 6 000 subjects completed the survey. The adjusted current prevalence of any mental disorder was 20.11% (95%CI 17.70%-22.85%). The six most prevalent specific disorders were major depressive disorder (9.20%), pain disorder (2.71%), mood disorder due to the body condition (2.08%), generalized anxiety disorder (1.99%), anxiety disorder not otherwise specified (1.15%) and dysthymic disorder (0.84%). The lifetime prevalence of mental disorders was 20.54% (95%CI 18.40%-23.39%). The overall current prevalence of mental disorders was higher in women (242.89‰) than in men (119.55‰), and the unmarried (248.37‰) was higher than those married (187.53‰). There was no significant difference in the prevalence of mental disorders among different age groups (P>0.05). The GAF score of mental disorders was 56±11, and 71.82% was moderate to severe functional impairment. Conclusions: The prevalence of mental disorders is high in rural left-behind population aged 60 years and over in Gansu Province. Major depression is a condition that deserves special attention.

Abstract
BACKGROUND Psychosocial concerns represent important outcomes in studies of treatments for acne and acne scarring. Also important, but largely overlooked, is the concept of appearance. OBJECTIVES To design an acne-specific patient-reported outcome measure for acne and acne scarring. METHODS We used a mixed-methods approach. Phase I involved 21 patient interviews that were audio-recorded, transcribed and coded. Concepts were identified and developed into scales that were refined through 10 cognitive interviews and input from 16 clinical experts. Phase II involved data collection at hospital and community-based dermatology clinics in Canada and the U.S.A. Eligible participants were aged 12 years and older with acne and/or acne scars on the face, chest and/or back. Rasch Measurement Theory (RMT) analyses were performed to examine psychometric properties. RESULTS Phase I led to the development of seven scales that measure appearance of facial skin, acne (face, chest and back) and acne scars, acne-specific symptoms and appearance-related distress. In phase II, 256 patients completed the ACNE-Q. RMT analysis provided evidence that the items of each scale worked together conceptually and statistically. Most participants scored within the range of measurement for each scale (81·9-93·1%). Reliability was high, with person separation index values and Cronbach alpha values > 0·90 for the appearance scales, ≥ 0·87 for appearance-related distress and ≥ 0·75 for symptoms. Worse scores on appearance scales correlated with worse symptom scores and more appearance-related distress. CONCLUSIONS The ACNE-Q is a rigorously developed instrument that can be used to measure appearance and other patient-centred concerns. What's already known about this topic? Acne is a common dermatological condition that can have an important impact on psychosocial function. Current patient-reported outcome measures specific to acne focus mostly on measuring psychological and social impact. What does this study add? The ACNE-Q provides a set of independently functioning scales that measure appearance of facial, back and chest acne, acne scarring and facial skin. Additional scales measure appearance-related distress and acne symptoms. What are the clinical implications of this work? ACNE-Q provides the dermatology community with a rigorously developed patient-reported measure for acne that can be applied in clinical trials, research and patient care. The measurement of appearance by ACNE-Q scales is more comprehensive than in other instruments providing important information on appearance of their acne and/or acne scars from the patient perspective.

Abstract
Objective: To describe the secular trends of institutional delivery (ID) rate in minority inhabited areas of China from 1996 to 2017 according to national health policies. Methods: The number of live births and IDs for each county/district in 31 provinces of China were derived from the datasets collected by the Office for National Maternal & Child Health Statistics of China. Information on health policies and ethnical areas was derived from official governmental websites. The calendar years were divided into three periods: pre-program period (1996 to 1999), program implementation period (2000 to 2008) and post-program period (2009 to 2017). Minority autonomous regions, autonomous prefectures, and autonomous counties were defined as minority inhabited areas. The ethnic that a county was classified into was determined by a principle of close proximity to the name of the county or its next higher level administrative division. A total of 700 counties in minority inhabited areas were included in the analysis. Results: A total of 45 684 265 live births including 35 098 855 delivered in institutions were analyzed. The ID rate in minority inhabited areas was 37.5% (696 221/1 856 164) in 1996 and 99.2% (2 371 209/2 390 131) in 2017, with an annual growth rate of 4.7%. During the 22-years period, the ID rates in the eastern, central and western regions increased simultaneously, with the annual growth rates of 3.1%, 4.2% and 4.9% respectively. The difference between the eastern and western regions decreased steadily from 16% in 1996 to <1% in 2017 and the difference between the urban and rural areas decreased from 32.1% in 1996 to <1% in 2017. Besides, the ID rates in Tibetan and Yi inhabited areas with lower baseline levels increased 73 and 63 percentage points respectively. The number of counties with the ID rate of <96% were substantially reduced from 589 in 1996 to 72 in 2017; the 71 counties were all located in national deep poverty-stricken areas named Three Districts and Three States, predominantly involving Tibetan (58), Yi (6), Uygur (2) and Lisu (2) ethnics. Conclusion: During the past 22 years, the ID rate in minority inhabited areas in China has dramatically increased, achieving the goal of 2 020 ahead of schedule, but there remains a few western counties where ID rates are still<96%, indicating that minority inhabited western areas should be focused in developing national policies concerning institutional delivery.

Abstract
Objective: To analyze the clinical and genotypic characteristics of infantile inflammatory bowel disease (IBD). Methods: The age of onset, family history, clinical manifestations, and treatment effect were retrospectively analyzed in 39 infants (male 23 cases, female 16 cases) with IBD who were admitted to the Department of Gastroenterology in Children's Hospital, Capital Institute of Pediatrics from January 2007 to December 2017. Next generation sequencing (NGS) based on target gene panel was used for gene analysis in 17 patients. Results: The median age of onset was 0.5 (0.5, 1.0) month. The most common clinical symptoms included diarrhea (39, 100%), malnutrition (38, 97%), hematochezia (34, 87%), fever (25, 64%), and perianal diseases (24, 61%). Four children had associated family history. Among the 17 patients whose gene was analyzed, 10 were found to have the pathogenic gene variation, within whom 7 had interleukin-10 receptor α subunit (IL-10RA) mutation, 2 had CYBB heterozygous mutation, 1 had interleukin-10 receptor β subunit (IL-10RB) mutation. The therapeutic medicine included mesalazine, steroids, and thalidomide. Eighteen children (46%) reached clinical remission (10 cases) or partial remission (8 cases). Conclusions: The incidence of single gene mutation in infants with IBD is high, with IL-10RA mutation as the most common. Refractory diarrhea and malnutrition may indicate infantile IBD.

Abstract
Abstract Objective To evaluate the efficiency of REPLI-g® Single Cell Kit for sample DNA amplification, and explore its application value in forensic trace DNA amplification. Methods Three DNA extraction kits were selected to extract DNA from peripheral blood of 10 unrelated individuals. The DNA yield and purity of the three DNA extraction kits were compared. According to the results of comparison, one DNA sample was selected to concentrate and dilute, then used as the initial sample of whole genome amplification (WGA). REPLI-g® Single Cell Kit was used to amplify the initial sample at the whole genome level. The amplification yield and amplification times were calculated, and the distribution of DNA fragments was detected by agarose gel electrophoresis. Goldeneye® DNA ID System 20A Kit was used to perform the STR typing of the initial sample and DNA samples amplified at the whole genome level to evaluate the performance of REPLI-g® Single Cell Kit in trace DNA amplication in terms of purity and yield as well as the success rate of STR typing. Results After comparison, one DNA sample was selected from QIAsymphony® DNA Investigator® Kit extracts to concentrate and dilute as the initial sample of WGA. After amplifying the whole genome of a series of initial samples by REPLI-g® Single Cell Kit, the lowest average of amplification yield reached 8.77×103 ng, while the average of the corresponding amplification times reached 1.40×106. DNA fragments were large and concentrated. The STR typing success rate of WGA samples became lower with the decrease of initial samples used, but when the amount of samples was lower than 0.5 ng, the STR typing success rate of samples after DNA WGA was higher than that of samples without DNA WGA. Conclusion REPLI-g® Single Cell Kit can increase the yield of template DNA. Especially for trace DNA, the STR typing success rate can be improved to a certain extent.

Abstract
BACKGROUND Small non-coding RNAs (sncRNAs) accomplish a huge variety of biological functions. Over the past decade, we have witnessed the substantial progress in the epididymal sncRNA studies. In the Epididymis 7, we had the true privilege of having a whole session to share our findings and exchange ideas on the epididymal sncRNA studies. OBJECTIVES This mini-review attempts to provide an overview of what is known about the sncRNAs in the mammalian epididymis and discuss the future directions in this field. METHODS We surveyed literature regarding the sncRNA studies in the mammalian epididymis, and integrated some of our unpublished findings as well. We focus on the progress in methodology and the advances in our understanding of the expression and functions of epididymal sncRNAs. RESULTS AND DISCUSSION The applications of high-throughput approaches have made great contributions in the discovery of new sncRNA species and profiling their dynamics in the epithelial cells, the passing spermatozoa, and the luminal environment. The diverse classes of epididymal sncRNAs exert important biological functions from the in situ regulation of epididymal gene expression to the epigenetic inheritance in the offspring. CONCLUSION Although still in its infancy, we believe that the research on epididymal sncRNAs will not only lead to a better understanding of their physiological and pathological functions, but also contribute to the whole landscape of the RNA field.

Abstract
Objective: To explore the effects of vitamin D3 on intestinal mucosal barrier of mice with severe burns. Methods: Forty-two C57BL/6C male mice aged eight to twelve weeks were divided into vitamin D3 vehicle+ sham injury group of seven mice, vitamin D3 vehicle+ burn injury group of fourteen mice, vitamin D3+ sham injury group of seven mice, and vitamin D3+ burn injury group of fourteen mice according to random number table. Mice in vitamin D3 vehicle+ sham injury group and vitamin D3 vehicle+ burn injury group were injected with vehicle of vitamin D3 at a dose of 0.1 mL intraperitoneally at 1, 24, and 48 h before burn experiment. Mice in vitamin D3+ sham injury group and vitamin D3+ burn injury group were injected with vitamin D3 at a dose of 100 ng/kg dissolved in 0.1 mL vehicle intraperitoneally at the same time points. Mice in vitamin D3 vehicle+ burn injury group and vitamin D3+ burn injury group were inflicted with 30% total body surface area full-thickness dermal scald (hereinafter referred to as burn) on the back by 98 ℃ hot water for 3 to 4 seconds. And mice in vitamin D3 vehicle+ sham injury group and vitamin D3+ sham injury were treated with 37 ℃ water on the back for 3 to 4 seconds to simulate injury. Seven mice in vitamin D3 vehicle+ sham injury group and seven mice in vitamin D3+ sham injury group at post injury hour (PIH) 24, and seven mice in vitamin D3 vehicle+ burn injury group and seven mice in vitamin D3+ burn injury group at PIH 6 and 24 were sacrificed respectively to collect mesentery lymph nodes, spleens, livers, and intestinal tissue. The mesentery lymph nodes, spleens, and livers of mice in each group were collected to observe growth of bacteria, and number of bacteria was counted. Intestinal tissue of mice in each group was collected to detect protein expressions of zonal occludin 1 (ZO-1) and occludin by immunohistochemistry staining method, distribution of ZO-1 by immunofluorescence staining method, and expression of occludin by Western blotting. Data were processed with Kruskal-Wallis H test, Nemenyi test, one-way analysis of variance, t test, and Bonferroni correction. Results: (1) At PIH 6 and 24, bacterial counts of mesentery lymph nodes, livers, and spleens of mice in vitamin D3 vehicle+ burn injury group were significantly higher than those of mice in vitamin D3 vehicle+ sham injury group (P<0.05). At PIH 6, bacterial counts of livers and spleens of mice in vitamin D3+ burn injury group were significantly lower than those of mice in vitamin D3 vehicle+ burn injury group (P<0.05). At PIH 24, bacterial counts of mesentery lymph nodes and livers of mice in vitamin D3+ burn injury group were significantly lower than those of mice in vitamin D3 vehicle+ burn injury group (P<0.05). (2) At PIH 6 and 24, expressions of ZO-1 and occludin of intestinal tissue of mice in vitamin D3 vehicle+ burn injury group were significantly lower than those of mice in vitamin D3 vehicle+ sham injury group, and expressions of ZO-1 and occludin of intestinal tissue of mice in vitamin D3+ burn injury group were close to those of mice in vitamin D3+ sham injury group. At PIH 6 and 24, expressions of ZO-1 and occludin of intestinal tissue of mice in vitamin D3+ burn injury group were significantly higher than those of mice in vitamin D3 vehicle+ burn injury group. (3) At PIH 6 and 24, compared with that of mice in vitamin D3 vehicle+ sham injury group, distribution of ZO-1 of intestinal mucosal epithelium of mice in vitamin D3 vehicle+ burn injury group was discontinuous. Distribution of ZO-1 of intestinal mucosal epithelium of mice in vitamin D3+ sham injury group was normal, and the distribution of ZO-1 of intestinal mucosal epithelium of mice in vitamin D3+ burn injury group was with good continuity. (4) At PIH 6 and 24, expressions of occludin of intestinal tissue of mice in vitamin D3 vehicle+ burn injury group were 0.720±0.003, 0.638±0.052 respectively, significantly lower than 0.918±0.003 of mice in vitamin D3 vehicle+ sham injury group (t=57.33, 5.36, P<0.05). At PIH 6 and 24, expressions of occludin of intestinal tissue of mice in vitamin D3+ burn injury group were 0.994±0.058, 1.064±0.060, close to 0.938±0.023 of mice in vitamin D3+ sham injury group (t=0.91, 1.96, P>0.05). At PIH 6 and 24, expressions of occludin of intestinal tissue of mice in vitamin D3 vehicle+ burn injury group were significantly lower than those of mice in vitamin D3+ burn injury group (t=4.75, 5.35, P<0.05). Conclusions: Intestinal bacterial translocation can occur in the early stage of severe burn. And vitamin D3 plays a protective role in the intestinal mucosal barrier post severe burn to reduce the bacterial translocation by protecting tight junction proteins of intestinal epithelium.

Abstract
Objective: To explore the efficacy of tenofovir disoproxil and adefovir dipivoxil treatment in patients with hepatitis B virus e antigen (HBeAg) negative was analyzed through the comparison of highly sensitive HBV viral load monitoring with HBV genotyping and drug resistance mutations. Methods: The clinical data of newly diagnosed chronic hepatitis B patients from January 2015 to June 2017 in outpatients and inpatients were randomly divided into tenofovir and adefovir group. Quantitative detection of HBV DNA levels before therapy and at 12, 24, 48, 96, and 120 weeks after therapy were determined for HBV genotypes and drug-resistant mutations in HBeAg-negative patients. Student's t-test was used to compare the measurement data between groups. The data of comparison between groups were tested by χ (2). Results: A total of 106 cases of HBeAg-negative patients were collected. Tenofovir disoproxil had a higher rate of HBV DNA suppression (54%) than adefovir dipivoxil treatment (42%), but the difference was not statistically significant (P = 0.19). After 120 weeks of treatment, a total of 46 patients (93.9%) were enrolled in the tenofovir disoproxil group with HBV DNA quantitation < 2 000 IU / ml. Adefovir dipivoxil group of patients with HBV DNA < 2 000 IU / ml a total of 40 cases, accounting for 75.5%. The difference between the two groups was statistically significant (P < 0.05). For 49 cases of HBeAg-negative patients, HBV B, C, B and C were mixed before tenofovir dipivoxil treatment, and C1653T, A1762T and G1764A mutation sites were detected in patients with D genotype. Patients C, B, C, B, and C were examined for C1673T, G1896, G1858, G1899A. After treatment, the detection rate of the above mutation sites decreased, but C1653T, C1673T and G1899A were not detected. New mutation sites such as G1915A / C, L180M, M204V, V207I / L, T184A and V173L were detected, Low resistance rate (25%). Conclusion: Tenofovir disoproxil can be recommended as a treatment for HBeAg-negative patients. For HBeAg-negative patients, the choice of high-sensitivity detection of HBV DNA levels, better monitoring of anti-HBV efficacy.

Abstract
Deepening of wounds not only prolongs the wound repair time, increases the chance of scar formation after healing, but also is one of the important causes of death in severe burn patients. How to prevent wound deepening is a clinical problem in the treatment of burns. The mechanism of deepening burn wounds has not been fully elucidated, and the prevention and treatment measures in clinic need to be further explored. Based on the research results of the early deepening mechanism and prevention measures of burn wounds at home and abroad, this paper intends to summarize the three aspects including deepening mechanism, prevention measures, and research prospects of burn wounds.

Objective: To understand the prevalence of drug resistance in treatment-naive HIV infected men who have sex with (MSM) in Guangzhou. Methods: HIV-1 RNA were extracted from the serum specimens of the MSM newly confirmed to be HIV-1 positive, living in Guangzhou and receiving no anti-viral therapy from 2008 to 2015. HIV-1 pol gene segments, including full protease and part reverse transcriptase, were amplified by nested reverse transcription polymerase chain reaction (nested-PCR) and sequenced by Sanger. Subsequently, the sequence data were submitted to Stanford University HIV Drug Resistance Database for drug resistance analysis. Results: Among 2 283 HIV infected MSM, HIV-1 pol gene segments were obtained from the serum samples of 1 986 HIV infected MSM aged 16-84 (30.18±8.24) years. Among them, the unmarried accounted for 74.17% (1 473/1 986), those of Han ethnic group accounted for 90.64% (1 800/1 986), those with education level of college or above accounted for 49.65% (986/1 986), those with education level of senior high school or secondary school accounted for 27.14% (539/1 986), those with education level of junior high school or below accounted for 20.89% (415/1 986). The distribution of subtypes was predominated by CRF07_BC (38.22%, 759/1 986) and CRF01_AE (34.49%, 685/1 986). The overall prevalence of drug resistance was 3.32% (66/1 986). The prevalence of resistance to protease inhibitors (PIs), nucleoside reverse transcriptase inhibitors (NRTIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs) were 1.36%(27/1 986), 0.65% (13/1 986) and 1.61% (32/1 986), respectively. Subtype B had higher resistance to PIs, NRTIs and NNRTIs and subtype CRF55_01B had highest resistance to NNRTIs compared with other subtypes. In subtype B, the resistant rates to D4T, EFV and NVP were highest (all 4.17%, 5/120), followed by those to NFV, AZT and RPV (all 3.33%, 4/120). In subtype CRF55_01B, the resistant rates to EFV and NVP were highest (all 5.50%, 16/291), followed by those to ETR and RPV (all 5.15%, 15/291). Conclusions: The prevalence of drug resistance in treatment-naive HIV infected MSM in Guangzhou remained at low level and current antiretroviral drugs are generally effective. However, subtype B and CRF55_01B have higher drug resistance.

Abstract
Objective: To compare the differences of brain functional damage of subtypes of patients with Cushing's syndrome (CS). Methods: A total of 11 adrenocorticotropic hormone (ACTH)-dependent CS patients and 29 ACTH-independent CS patients were recruited from Chinese PLA General Hospital between September 2015 and March 2017 with confirmed CS. The psychiatric scales and brain task functional magnetic resonance imaging (fMRI) were evaluated. Results: A total of 40 patients (34 females, 6 males) with a mean age of (39.20±12.10) years and a median education level of 12 (9, 16) years were enrolled. ACTH-dependent patients had significantly worse performance than the ACTH-independent patients in response to the depression evaluation (64.6±6.1 vs 56.2±12.8, P=0.008), positive emotion (17.8±4.2 vs 24.3±7.2, P=0.008) and CS life quality [31(29,33) vs 42(29,51), P=0.040]. In the reaction to positive target pictures, ACTH-dependent CS patients showed stronger activation in left superior temporal gyrus compared with patients in ACTH-independent group, while the activation degree of their bilateral dorsal anterior cingulate cortex, bilateralsuperior frontal gyrus and left middle frontal gyrus was much worse. In the reactions to negative target pictures, ACTH-dependent CS patients had weaker activation in bilateral cerebellum, left superior frontal gyrus, left middle frontal gyrus, left precuneus and right postcentral gyrus, compared with patients in the ACTH-independent CS group (P<0.01, AlphaSim corrected). The activation degree of some regions whose brain function was different between the two groups was correlated to the cortisol level, ACTH level, 24 h urinary free cortisol (UFC) level, depression evaluation and negative emotion assessment (all P<0.05). Conclusions: The severity of the depression and the life quality of patients in ACTH-dependent group are worse than ACTH-independent CS patients. The brain function of ACTH-dependent CS patients is much weaker.

Abstract
Developments in analytical chemistry technology, especially the combination between the partial least squares and spectroscopy, have contributed significantly to predicting the chemical concentrations and discriminating similar chemical analytes. However, spectral shift is an unwanted but inevitable factor for the spectroscopic analyzer, especially in practical application, which decreases the method's accuracy and stability. To remove the term of spectral shift completely and increase the robustness of spectroscopic analysis method, Fourier transform based partial least squares method was proposed. The approach used Fourier transform first to transform the spectral shift in the "time domain" to the phase term in the "frequency domain." The module of the Fourier transformed spectra was then calculated. As a result, the phase term was removed (the module of the phase term is 1), which means the spectral shift term was removed completely. Finally, the spectra modules were used to build the model and validate. The approach's advantages are: (i) that the approach provides a new insight to treat the spectral shift in spectroscopic analyzer; (ii) that the model is insensitive to spectral shift; (iii) that the approach makes partial least squares combined with spectroscopy more suitable for practical application, rather than lab experiment, because spectral shift is permitted, which means the decreased requirements of measure environment. As an example, blood species discrimination, using Raman spectroscopy, was used in order to demonstrate this approach's effectiveness.

Abstract
Objective: To investigate esophageal motility and reflux characteristics in gastroesophageal reflux disease (GERD) with and without extra-esophageal symptoms by high-resolution manometry and 24 h esophageal multichannel intraluminal impedance combined pH (MII-pH) monitoring. Methods: From February 2016 to June 2017, GERD patients with and without extra-esophageal symptoms were enrolled in this prospective controlled study. Esophageal HRM and 24 h MII-pH monitoring were performed. The differences in esophageal motility and reflux parameters were further analyzed between 30 GERD patients with extra-esophageal symptoms and 30 simple GERD patients. Results: The GERD symptom scores didn't show statistical difference between two groups. The GERD symptom scores didn't show statistical difference between two groups. The relaxation pressure of lower esophageal sphincter(LES), the integrated relaxation pressure, and the recovery time of upper esophageal sphincter(UES) of GERD patients with extra-esophageal symptoms were all lower than those of patients without extra-esophageal symptoms [(15±7) vs (21±11)mmHg, (8±3) vs (10±5)mmHg, (388±168) vs (492±170)ms, 1 mmHg=0.133 kPa], and the differences were statistically significant(all P<0.05). The main classification of esophageal motility type of GERD patients with extra-esophageal symptoms was mild esophageal motility disorders (27%, 8/30), and the occurrence of ineffective esophageal motivation was 20% (6/30), which were similar with simple GERD patients. The proximal reflux percentages of weak acid reflux and nonacid reflux, abnormal nonacid reflux in GERD patients with extra-esophageal symptoms were significantly higher than those in simple GERD patients [84.6% (73.2%, 100.0%) vs 75.0% (60.0%, 87.65%), P=0.048; 90.0% (45.8%, 100.0%) vs 0(0, 100.0%), P=0.017; 46.7% vs 3.3%, P=0.03]. Conclusions: The pathogenesis of GERD with extra-esophageal symptoms may be different from typical GERD. Increase of proximal esophageal reflux and abnormal nonacid reflux may all participate in the mechanisms of GERD with extra-esophageal symptoms.

Abstract
Objective:To explore the diagnostic value and optimal diagnostic threshold of reflux symptom index(RSI) in allergic patients with laryngopharyngeal reflux. Method: All the adult allergic patients with respiratory tract symptoms completed the RSI with the consent of the patients. A total of 150 patients with RSI>13 were screened out. The LPR patients were confirmed by 24 h pH-metry of pharyngo-laryngoesophageal (allergic group). The same number of non allergic laryngeal reflux patients were selected as control group (non allergic group). The ratio of RSI>13 to LPR was calculated. The total score of RSI and each score were compared between the allergic group and the non allergic group. ROC curve was used to analyze the highly suspicious RSI score thresholds for patients with reflux laryngitis. Result:Only 53(35.33%) of 150 patients with RSI>13 were diagnosed as LPR after 24 h pH-metry test in allergic patients. Among the 9 symptoms of RSI, the scores of 6 symptoms in allergic group were significantly higher than those in non allergic group(P<0.05). The average RSI score of allergic group was 23.57±3.17. The average RSI score of non allergic group was 17.57±2.64. The total score of allergic group was higher than that of non allergic group(P<0.05). According to the RSI score ROC curve of allergic group, the area under 95% confidence interval curve was 0.815. RSI had certain diagnostic accuracy for allergic patients with LPR. The best critical value of RSI score for allergic patients with LPR was 18, the sensitivity was 94.3%, and the specificity was 56.7%. Conclusion:RSI can be used to screen allergic patients with LPR, diagnostic score threshold RSI>18 points, has a certain diagnostic accuracy.

Abstract
Objective: To compare the effects of different types of anesthesia on postoperative cardiopulmonary complications in patients aged 80 years and above who received unilateral hip fracture surgery. Methods: The perioperative data of patients aged 80 and above who underwent unilateral hip fracture surgery in Peking Union Medical College Hospital from July 2009 to June 2014 were collected and grouped based on the types of anesthesia including general anesthesia, neuraxial anesthesia, and peripheral nerve block. Variables were analyzed including preoperative general conditions (age, sex, type of fracture, ASA physical status classification, preoperative cardiopulmonary complications), intraoperative conditions (type of surgical procedure, operative time, blood loss, total intraoperative fluid infusion), and postoperative conditions (length of hospital stay, postoperative hospital stay, ICU stay, postoperative newly developed cardiopulmonary complications, postoperative in-hospital death, hospitalization costs). The incidences of postoperative cardiopulmonary complications of each group were analyzed and compared. Results: A total of 219 cases were finally analyzed including general anesthesia (n=46), neuraxial anesthesia (n=90) and nerve block group (n=83). Fewer cases with preoperative pulmonary complications were noticed in general anesthesia group (15 cases, 32.6%) than in neuraxial anesthesia group (45 cases, 50%) and nerve block group (47 cases, 56.6%) (χ(2)=6.912, P=0.032). No statistical differences were found between groups regarding preoperative cardiovascular complications and other variables. There were no significant differences in postoperative cardiopulmonary complications. However, the cost of hospitalization was lower in neuraxial anesthesia group (45.6±21.4) thousand RMB and nerve block group (48.2±25.8) thousand RMB compared with general anesthesia group (56.3±21.6) thousand RMB, the difference was statistically significant(F=9.951, P=0.007). Conclusions: For elderly patients undergoing unilateral hip surgery, the type of anesthesia does not affect the incidence of postoperative cardiopulmonary complications. However, neuraxial anesthesia and nerve block may reduce the cost of hospitalization.

Abstract
Objective: To investigate the clinicopathologic features and prognosis of gastrointestinal mantle cell lymphoma (GI-MCL). Methods: Clinical data of 38 GI-MCL patients diagnosed at Beijing Friendship Hospital from January 2002 to January 2016 were retrospectively reviewed morphologically and immunophenotypically. IgH/CCND1 gene fusion was assessed by fluorescent in situ hybridization (FISH). For comparison, 60 cases of non-GI-MCL were randomly selected to extract the differences inclinicopathological features and patient survival between the two groups. Results: Of 38 patients with GI-MCL, the median age was 62 years (range: 35-78 years, 23 males and 15 females), of which patients of 60 years of age or older accounted for 55.3%. Patients with clinical course of less than 6 months accounted for 81.1%(30/37). The main symptoms included abdominal pain, diarrhea, anorexia and hematochezia. Those with B symptoms accounted for 32.4%(12/37). The tumor most often involved lleocecal region (57.9%, 22/38), followed by rectum (36.8%, 14/38) and sigmoid colon (28.9%, 11/37), and the stomach accounted for 18.4%(14/38). Endoscopic polypoid lesions were found in 33 cases (86.8%, 33/38), of which 22 cases (66.7%, 22/33) were multiple. Five cases (13.2%, 5/38) presented with local protuberant neoplasm. According to Ann Arbor staging, 3 cases (7.9%, 3/38) were at stage Ⅰ, 4 cases (10.5%, 4/38) were at stage Ⅱ, and 31 cases (81.6%, 31/38) were at stage Ⅳ. The number of patients with tumor involvement of abdominal and retroperitoneal lymph nodes accounted for 45.7%(16/35), including 41.7%(15/36) involving the superficial lymph node, 17.1%(6/35) involving extranodal sites, and 23.5%(8/34) having splenomegaly. All of the 38 cases were classic MCL, and the tumor was composed of uniform lymphoid cells and effacing normal mucosal structure. All tumors were positive for CD20 and CD5. 97.4% (37/38) tumors were positive for cyclin D1, and 92.0% (23/25) tumors were positive for SOX11. FISH test was positive in 1 case of cyclin D1 negative tumor. Twenty-eight patients (73.7%) had a median follow-up of 25.0 months (range: 3-79 months). The 3-year survival rate for stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ of patients were 80.0% and 69.1%, respectively (P> 0.05). The 3-year survival rate for GI-MCL and non-GI-MCL patients were 71.7% and 72.5%, respectively (P>0.05). Single factor analysis showed that age of >60 years and splenomegaly were correlated with a worse overall survival rate (P<0.05). Conclusions: Gastrointestinal malaise is the most common presenting symptom in GI-MCL patients. GI-MCL more commonly involves colorectum with more frequent multiple polypoid lesions. Patients of age >60 years and with splenomegaly have poor prognosis. There is no difference in the prognosis between GI-MCL and non-GI-MCL patients.

Abstract
OBJECTIVES To synthetically analyse the medical malpractice cases of cardiac death in forensic identification, and to explore the generality and characteristic of cause of death, medical malpractice and assessment of participation degree. METHODS Totally 52 medical malpractice cases of cardiac death examined in the Xiaoshan Branch Office, Hangzhou Minghao Forensic Judical Appraisal Institute, from January 2015 to April 2018 were collected. The general information of cases, medical institutions and situations of hospital stay, cause of death, medical malpractice and assessment of participation degree were retrospectively analysed. RESULTS In 52 cases, the male to female ratio was 2.25:1, and most subjects aged >50-60. Cardiac death caused by hypertensive heart disease or coronary heart disease was most common (67.3%), followed by viral myocarditis and cardiomyopathy (13.5%). There were 24 cases involved surgery, and the survival time after surgery was from 1 h to 118 d with a 7 d medium value. There were 63 medical institutes involved in these medical malpractices. Medical malpractice presented in most hospitals more or less, and the participation degree was >20%-30%. CONCLUSIONS Forensic appraisal contributes to determine causes of death, which not only provides scientific evidence for medical malpractice identification, but also improves diagnosis and treatment levels of medical institutions.

Abstract
OBJECTIVES Physical activity contributes to preventing type 2 diabetes (T2D). Doing housework is an unstructured mild-intensity physical activity. We aimed to investigate the association between household physical activity level (HPAL) and T2D in urban Chinese men. STUDY DESIGN This is a cross-sectional study. METHODS This study contained 13,862 male adults aged 35-78 (48.4 ± 7.1) years. According to the self-reported time (hours/day [h/d]) spent on housework, they were stratified into three levels: 0 h/d, >0-2 h/d, and >2 h/d. The association of HPAL with T2D was investigated by logistic regression analysis. RESULTS The odds ratios (ORs) for T2D across increasing categories of HPAL were 1.00 (reference), 0.80 (95% confidence interval [CI] 0.72-0.89), and 0.60 (95% CI 0.51-0.70), respectively (P for trend <0.001), after adjusting for confounding factors. Further adjustment for waist circumference or body mass index (BMI) had a minimal impact on these ORs. The inverse association of HPAL with T2D was persistent in subgroup analyses based on age, hypertension, family history of diabetes, smoking, BMI, waist circumstance, and fasting plasma glucose level. CONCLUSION Our findings indicated that HPAL was inversely associated with the risk of T2D among urban males in northern China. This implied that household physical activity may contribute to long-term glucose control. Well-designed longitudinal studies are required to improve our understanding of this association.

Abstract
OBJECTIVE To compare the effects of different sized titanium dioxide (titanium dioxide, TiO2) on the antioxidant function of liver tissues in mice, and study the effect of TiO2 nanoparticles on the susceptibility of lipopolysaccharide (LPS) on liver tissues. METHODS Ninety 4-week-old clean-grade male ICR mice were divided into 18 groups, in which the mice were fed for different feed involving ordinary feed, nanometer TiO2 feed which meant the feed including 1% (mass fraction) TiO2 nanoparticles, and submicron TiO2 feed which meant the feed including 1% (mass fraction) TiO2 submicron particles. Respectively, they were fed for 1 month, 3 months and 6 months. On the second day after the feeding, respectively, 0 and 10 mg/kg LPS were given by gavage. The mice were harvested after 4 h and the body weight and liver weight for calculating the liver coefficient were recorded. Then the liver tissue homogenates were prepared for determining the antioxidant indexes including the total antioxidant capacity (T-AOC), total superoxide dismutase (T-SOD), glutathione peroxidase (GSH-PX), and malondialdehyde (MDA). RESULTS The change of body weight in mice was only discovered in group fed for 1 month, which showed significant decrease of body weight in treatment groups compared with control group. And there was no significant change of the liver coefficient in each group. Compared with control groups, nanometer TiO2 groups and submicron TiO2 group, the activity of T-AOC, T-SOD and MDA of nanometer TiO2+LPS group and submicron TiO2+LPS group in which the mice were fed for 1 month and 6 months increased in different degree. And another result was also existing. The MDA activity of liver in different sized treatment groups fed for 3 months decreased. Neither significant difference between the results of different sized TiO2 treatment groups, nor significant difference among different sized TiO2 groups and the control groups were observed. CONCLUSION Longterm peroral TiO2 nanoparticles and TiO2 submicron particles are more likely to cause damage to the liver in the growing mice, and the damage may be either reductive or oxidative. In addition, small sized TiO2 can increase the susceptibility of mice liver to LPS and the susceptibility will increase with the increase of exposure time.

Fever was noted in 122 patients (78.2%), 108 patients had lymphadenopathy (69.2%), and 75 patients had hepatosplenomegaly (48.1%). Thirty-three cases were grade 1, 68 cases were grade 2, and 55 cases were grade 3. TCR gene arrangement analysis was performed in 45 cases, and 33 cases (73.3%) showed clonal rearrangement. The follow-up period ranged from 1-134 months, and 44 patients (28.2%) died. There was a trend of increased death rate associated with increasing grade (P>0.05). Conclusions: There are many types of EBV(+) T/NK-LPD, and they can be classified as systemic, relatively localized and localized. The prognosis should be based on a comprehensive analysis of pathology and clinical data. There is no significant correlation between morphological grade and mortality. An important goal of therapy is to prevent serious complications.

Abstract
Objective: To investigate clinicopathologic features and prognostic factors of mantle cell lymphoma(MCL). Methods: The clinical data of 349 MCL patients diagnosed at Beijing Friendship Hospital from January 2004 to January 2016 were retrospectively collected. Corresponding histological sections were reviewed. Additional studies included immunohistochemical staining using the MaxVision two-step method, IgH/CCND1 fusion gene detection by fluorescent in situ hybridization (FISH), and correlative statistical analysis. Results: Of 349 patients with MCL, the median patient age was 61 years (range: 25-83 years, M∶F=2.7∶1.0) and the age of 243 patients ranged from 51 to 70 years (69.6%). Those with B symptoms accounted for 22.4% (70/313). Most of the patients presented with superficial lymphadenopathy and the clinical stage Ⅲ-Ⅳ accounted for 76.1% (235/309). Extranodal involvement was seen in 47.9% (148/309), among which the gastrointestinal tract accounted for 31.8% (47/148) and splenic involvement accounted for 15.4% (47/305). Three hundred and nine (88.5%) cases were of classical type and 40 (11.5%) cases were of aggressive variant type, and all were composed of proliferating lymphoid cells. All the tumors were positive for CD20 and cyclin D1, and 98.6% (344/349) tumors were weakly positive or positive for CD5. FISH test was positive in 12 cases that were CD5 negative and with cyclin D1 partial expression.Two hundred and forty-three (69.6%) patients had a median follow-up of 26 months (range: 3-108 months). The 3- and 5-year overall survival rates for patients were 63.0% and 34.8%, respectively. Single factor analysis showed that age of >60 years, splenic involvement, aggressive variant type, incompletely overlapping type [Based on the degree of overlap ≥90% and <90% between the follicular dendritic cell (FDC) meshwork and tumor cells, the tumors were divided into the completely overlapped type and incompletely overlapped type] and Ki-67 index >40% had poor prognosis (P<0.05). Multiple factor Cox proportional risk regression analysis after removing the aggressive variant type showed that age, splenic involvement, the degree of overlap between the FDC meshwork and tumor cells and Ki-67 index were independent prognostic factors for overall survival rate of MCL patients (P<0.05). Conclusions: MCL is more commonly found among middle-aged and elderly men. Patient age, splenic involvement, degree of overlap between FDC meshwork and tumor cells and Ki-67 index are the independent prognostic indicators for MCL.

Abstract
Objective: To understand the related risk behaviors, knowledge and status of HIV/AIDS infection among rural adults of Derung minority, to provide relevant messages for the development of HIV/AIDS intervention strategy in this minority group. Methods: We used system sampling method to conduct a cross-sectional survey in 6 administration villages of Derung Township, Gongshan Derung and Nu Autonomous County in Nujiang Lisu Autonomous Prefecture of Yunnan Province, with a sample size estimated as 383. Adult residents with Derung minority in six villages of Gongshan County were involved, with relevant information collected through door-to-door visit. HIV antibody was tested and SPSS 17.0 was used for statistical analysis. Results: Information on 394 valid respondents was collected, with age as between 18 and 65 (34.39±9.74), 80.7% (318/394) as married, 54.0% (213/394) having had primary school education, 13.2% (52/394) as migrant workers. In this population, the overall HIV infection rate appeared as 0.5% (2/400), mainly through sexually transmission. The rate of awareness on HIV/AIDS was 69.8% (275/394), mainly through free publicized materials 50.0% (197/394). Rates on premarital sexual behavior on multiple sexual partners in the past year, on temporary sexual partners in the past year, having commercial sexual experiences in the past year and ever used condoms when engaging in casual sex, were 6.4% (60/366), 18.0%(66/366), 5.7%(21/366), 1.9%(7/366) and 8.0%(25/311), respectively. Conclusions: Few numbers of HIV infections were identified among the migrating workers with Derung minority, with sexual transmission as the major route, along with the increased number of rural migrant workers and the low rates both on AIDS knowledge and condom use, accompanied by the high risk sexual behavior appeared in this rural adult residents of Derung minority. Relative strategies on HIV/AIDS intervention and control should be developed.

Abstract
Objective: To compare the clinical data, esophageal motility and reflux characteristic in patients with non-erosive reflux disease (NERD) and reflux esophagitis (RE). Methods: A total of 167 patients of NERD were enrolled in the study[60 males, 107 females, mean age(44.1±13.4) years old], and 151 patients of RE were enrolled [74 males, 77 females, mean age(46.5±9.9) years old]. All patients were surveyed by questionnaires to investigate the clinical data. All patients accepted the esophageal highresolution manometry and 24 hours pH+ impedance monitoring to investigate the esophageal motility and reflux characteristic. Results: The proportion of female patients in group NERD was significantly higher than that in group RE(60/107 vs 74/77, P=0.049). The reflux symptom scores and the proportion of reflux in group NERD were significantly lower than those in group RE[(4.5±2.4) vs (5.6±2.1), 44.91% vs 64.24%, P<0.05). The Demeester score of group NERD was significantly lower than that of group RE[12.54(1.60, 10.80) vs 17.31(3.40, 16.64), P=0.044]. The proportion of Demeester scores positive patients in group NERD was significantly lower than that in group RE(15.1% vs 23.8%, P=0.018). The number of acid reflux in group NERD was significantly lower than that in group RE[17.49(3.00, 22.22) vs 21.69(4.00, 30.00), P=0.042]. Conclusions: There are more female patients in group NERD. The reflux symptoms of the group NERD are less serious than those of group RE.RE patients have more acid reflux events. There is no significant difference in the esophageal motility between the two groups.

Abstract
BACKGROUND Lactation performance of dairy cow has considerably increased with animal breeding and management improvement in recent years. Ruminal net synthesised pantothenic acid is insufficient to meet the requirement of high producing dairy cows. The objective was to investigate the effects of rumen-protected pantothenate (RPP) on lactation performance, ruminal fermentation, nutrient digestion and blood metabolites in dairy cows. RESULTS Dry matter (DM) intake tended to increase, whereas milk yields, milk fat percentage and yield, body condition score (BCS) changes and net energy output except for maintenance increased linearly with increasing RPP supplementation. Ruminal pH and ammonia N concentration tended to decrease, total VFA tended to increase, while acetate-to-propionate ratio increased linearly with increasing RPP supplementation. Digestibilities of DM, organic matter and crude protein increased linearly, but neutral detergent fibre and acid detergent fibre digestibility tended to increase. Blood glucose, total protein, non-esterified fatty acids, pantothenic acid, pantothenate kinase, succinyl CoA, acyl carrier protein and acetyl CoA also increased linearly with increasing RPP supplementation. CONCLUSION The results indicated that supplementary RPP improved lactation performance, nutrient digestion and blood parameters in a dose-dependent manner, and the optimal dose was 12 g RPP per cow per day in the current study. © 2017 Society of Chemical Industry.

Abstract
Objective: To analyze clinical, pathological, molecular and genetic characteristics of Burkitt-like lymphoma with chromosome 11q aberration. Methods: A case of Burkitt-like lymphoma with 11q aberration was presented at Beijing Friendship Hospital in November 2016 with detailed clinicopathological features, immunophenotypes, Epstein-Barr virus(EBV) status and molecular genetic characteristics. Results: The patient was a 38-year-old man presenting with the cervical lymphadenopathy. In morphology, the tumor had the similar characteristics of Burkitt lymphoma, including diffuse infiltration of medium to large lymphoid cells, and presence of"starry sky"phenomenon. Immunophenotypically, the tumor cells were positive for CD20, CD10, bcl-6, but negative for bcl-2. MUM-1 showed weak and patchy positivity. Ki-67 index was more than 95%. C-MYC expression was seen in about 50% of tumor cells. EBV in situ hybridization was negative. IgH and IgK genes were clonally rearranged.Fluorescence in situ hybrization detection using MYC break probe was negative but ATM gene amplification on chromosome 11q was detected. The patient did not receive any chemotherapy or radiotherapy and had not recurrence during the 10 months follow-up. Conclusion: Burkitt-like lymphoma with chromosome 11q aberration has similar clinical, morphological and immunological characteristics to classic Burkitt's lymphoma.

Abstract
Objective: To investigate the molecular-cytogenetic characterization and impact on tyrosine kinase inhibitors (TKIs) therapy in chronic phase of chronic myeloid leukemia (CML-CP) patients with variant Ph chromosome (vPh). Methods: The clinical data of 32 patients with vPh chromosomes were collected and compared with 703 patients with typical Ph chromosome in newly diagnosed CML-CP who were on first-line imatinib (IM) and with BCR-ABL transcript of P210. Results: There was no significant difference in demographic and hematological characteristics between vPh and classic Ph patients. 3(9.4%) of the 32 vPh cases were simple variant translocations. Among the remaining 29 cases with complex variant translocations, 28 cases (87.5%) involved 3 chromosomes, and only 1 (3.1%) involved 4 chromosomes. Except for 8, 15, 18, X, and Y chromosomes, the other chromosomes were involved. The frequency of chromosome 12q(15.5%) and 1p (12.1%) were higher involved. The most common FISH signal pattern was 2G2R1Y (74.1%), followed by 1G1R2F (14.8%), 2G1R1Y (3.7%), 1G2R1Y (3.7%), 1G1R1Y (3.7%). The comparison of complete cytogenetic response (CCyR) (P=0.269), major molecular response (MMR) (P=0.391) were carried out between simple and complex mechanisms, without difference. Compared with the classic Ph, the patients with vPh had higher IM primary resistance rate (χ2=3.978, P=0.046), especially primary hematological resistance (χ2=7.870, P=0.005), but the difference of CCyR (χ2=0.192, P=0.661), MMR (χ2=0.822, P=0.365), EFS (χ2=0.509, P=0.476), OS (χ2=3.485, P=0.062) were not statistically significant, and multivariate analysis showed that the presence of vPh did not affect OS (RR=0.692, 95%CI 0.393-1.765, P=0.658)、EFS (RR=0.893, 95%CI 0.347-2.132, P=0.126) and PFS (RR=1.176, 95%CI 0.643-2.682, P=0.703). Conclusion: CML-CP patients with vPh and classic Ph had similar demographic and hematological characteristics. Except for 22q11, 9q34, the frequency of chromosome 12q and 1p were higher involved. The most common FISH signal pattern was 2G2R1Y, and different mechanisms had no impact on TKIs therapy. Compared with cases with classic Ph chromosomes, the patients with vPh chromosomes had higher risk of IM primary resistance, especially primary hematological resistance, which can obtain deeper molecular response quickly after changing to second-generation TKIs and didn't affect long-term outcomes and OS.

Abstract
Objective: To understand the prevalence of major human parasitic diseases and related factors in Henan province. Methods: This stratified sampling survey was carried out according to the requirement of national survey protocol of major human parasitic diseases, 2014-2015. The prevalence of soil-transmitted helminths infection, taeniasis and intestinal protozoiasis were surveyed in 104 sites selected from 35 counties (districts) and the prevalence of clonorchiasis was surveyed in 62 sites selected from 37 townships. In each survey spot, 250 persons were surveyed. A total of 26 866 persons and 15 893 persons were surveyed. Modified Kato-Katz thick smear was used to detect the eggs of intestinal helminthes. Tube fecal culture was used to identify the species of hookworm. The Enterobius eggs were detected in children aged 3 to 6 years by using adhesive tape. The cyst and trophozoite of intestinal protozoa were examined with physiological saline direct smear method and iodine stain method. Results: The overall infestation rate of intestinal parasites was2.02% in Henan, and the worm infection rate was higher than protozoa infection rate. Fourteen kinds of intestinal parasites were found, including nematode (5 species), trematode (2 species), and protozoan (7 species). The infection rate of Enterobius vermicularis was highest, and Qinba Mountain ecological area had the highest infestation rate of intestinal parasites in 4 ecological areas of Henan. There was no significant difference in intestinal parasite infection rate between males and females (χ(2)=3.630, P=0.057), and the differences in intestinal parasite infection rate among different age groups had significance (χ(2)=124.783, P=0.000 1). The infection rate reached the peak in age group ≤9 years and the major parasite was Enterobius vermicularis. Furthermore the overall human infection rate of parasite showed a downward trend with the increase of educational level of the people (χ(2)=70.969, P=0.000 1), the differences had significance (χ(2)=120.118, P=0.000 1). For different populations, the infection rate of intestinal parasites was highest among preschool children. The infection of intestinal helminth was mainly mild, only 2 severe cases were detected. The infection rate of Clonorchis sinensis in urban residents was only 0.006%. Logistic regression analysis showed that being preschool children (χ(2)=15.765, P=0.000 1) and drinking well water (χ(2)=45.589, P=0.000 1) were the risk factors for intestinal parasite infection, and annual income per capita of farmers was the protective factor against intestinal parasite infection. The infection rates of protozoa and intestinal parasites decreased sharply compared with the results of previous two surveys, and the rate of intestinal helminth infection also dropped sharply compared with the second survey. The numbers of protozoa, helminth and intestinal parasites detected in this survey were all less than the numbers found in the previous two surveys. Conclusions: Compared the results of three surveys in Henan, the infection rate of protozoa and intestinal parasites showed a downward trend. The prevention and treatment of Enterobius vermicularis infection in children should be the key point of parasitic disease control in the future.

Abstract
Objective: To investigate clinicopathological features and prognosis of tonsillar mantle cell lymphoma(TMCL). Methods: Clinical data of 25 patients with TMCL at Beijing Friendship Hospital, Capital Medical University from 2002 to 2016 were included. All the cases were reviewed microscopically. Various immunohistochemical stains were performed using the MaxVision two-step method. IgH/CCND1 gene fusion was detected by fluorescent in situ hybridization(FISH). Additionally, randomly selected 40 cases of non-tonsil MCL of the same period were compared. Results: Among all mantle cell lymphomas (MCL), TMCL accounted for 5.6%(25/449). The median age of the patients was 60 years(range: 44-82 years) with a M∶F ratio of 5.3 to 1.0. The main symptoms were sore throat and foreign body sensation and patients usually presented with enlargement or mass of tonsil. At the early stage of the disease, 18 cases(72.0%) were clinically misdiagnosed as tonsillitis. Lymph node involvement was present in 76.0%(19/25) of the patients. There were 4 cases(16.0%)with current splenic involvement, 11 cases(44.0%) with pharyngeal focal recidivism, and 3 cases(12.0%) with involvement of other non-lymphoid organs. Morphologically, tonsillar architectures were effaced at various degrees. Eighteen MCL cases showed classical type and 7 cases were blastoid variant. All tumors were positive for CD20 and cyclin D1. 92.0%(23/25) tumors showed weakly positive or positive expression for CD5. FISH test that IgH/CCND1 gene fusion was positive in two CD5 negative classical cases. 18 patients(72.0%) had a median follow-up time of 26 months(range: 6-81 months). The difference of survival rate between stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ patients was not statistically significant(P>0.05). Compared with NTMCL, TMCL was found to have higher proportion of stage Ⅰ-Ⅱ disease (χ(2)=12.789, P<0.01), lower the proportion of non-lymphatic organ involvement (χ(2)=8.125, P<0.01), and better prognosis (χ(2)=4.351, P=0.037). Conclusion: The incidence of TMCL is low and prone to be misdiagnosed as tonsillitis. Patients with TMCL are more likely at stage Ⅰ-Ⅱ at presentation and the prognosis is better than that of NTMCL.

Abstract
To explore the efficacy and influencing factors of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with myeloid leukemia and granulocytic sarcoma (GS). Clinical outcome including hematopoietic reconstitution, transplant-related complications, survival and relapse were collected and retrospectively analyzed in 9 patients with myeloid leukemia and GS after allo-HSCT. Hematopoiesis reconstitution was achieved in all the 9 recipients. Four cases developed acute graft-versus-host disease (GVHD), and 1 with chronic GVHD. The median follow-up time after transplantation was 10(4-81) months. Only 2 cases survived, the other 7 died of relapse. The median time of relapse after transplantation was 5(3-19) months. Allo-HSCT is relatively effective treatment for patients with myeloid leukemia and GS. Relapse after transplantation remains the major factor of mortality.

Abstract
OBJECTIVE To investigate serum IgG4 levels in different diseases and the changes of serum IgG4 levels in post treatment of IgG4 related disease. METHODS Clinical data of 620 patients who received investigation of serum IgG4 in Peking University People's Hospital from January 1, 2015 to March 31, 2016 were collected retrospectively. According to the difference of the diseases, they were divided into common group of diseases, autoimmune diseases and IgG4 related diseases; pancreatic disease patients were divided into autoimmune pancreatitis and pancreatic cancer group; According to different treatment stages of the disease, the patients with IgG4 related diseases were divided into pretreatment group and post treatment group. And the expressions of the patients'serum IgG4 levels in different groups were analyzed. RESULTS The median serum IgG4 level in the group of the patients with common diseases was 0.480(0.005, 50.400) g/L, in the group of autoimmune disease was 0.406 (0.003, 18.700) g/L , in the group of IgG4 related diseases was 5.200(0.046, 46.000)g/L, which was signi-ficantly higher in the group of IgG4 related diseases than the other two groups, and there was obvious statistical significance in serum IgG4 levels between the group of IgG4 related diseases and the other two groups (P<0.01); There was no obvious difference in serum IgG4 levels between the common disease group and the autoimmune disease group, and there was no obvious statistical difference in serum IgG4 levels between the two groups (P>0.05). In the patients with IgG4 related diseases, the median serum IgG4 level in the group of pretreatment patients was 6.540 (1.330, 34.100) g/L, and 3.735 (0.063, 46.000) g/L in the post treatment patients. Serum IgG4 levels decreased in post treatment group, signi-ficantly lower than in pretreatment, there was obvious statistical difference in serum IgG4 levels between the two groups (P<0.01). The median serum IgG4 level in the group of patients with autoimmune pancreatitis was 3.735 (0.063, 46.000) g/L ,and 0.438 (0.056, 1.130) g/L in the group of patients with pancreatic cancer,which was significantly higher in the group of patients with autoimmune pancreatitis than the others, and there was obvious statistical difference in serum IgG4 levels between the two groups (P<0.01). CONCLUSION Serum IgG4 levels in patients with different diseases were different, and were significantly higher in patients with autoimmune pancreatitis and IgG4 related diseases, so serum IgG4 levels can provide the basis for the differential diagnosis of different diseases; Serum IgG4 levels in patients with IgG4 related diseases decrease significantly after treatment, so it can be used as an important index to evaluate the curative effect of IgG4 related diseases.

Abstract
Objective: To construct a three-dimensional (3D) finite element model and analyze the biomechanical characteristics during mandibular second molar mesialization using customized lingual appliances and mini-implant. Methods: One adult student volunteer from The First Affiliated Hospital of Zhengzhou University with lower left first molar extraction was selected. After CT scanning, Mimics, Geomagic, ANSYS were employed to develop a 3D finite element model including customized lingual brackets, stainless steel lingual arch wire, buccal buckles, lower dentition, periodontal ligaments and alveolar bone. Four different loading methods (1. the force of 1.470 N loaded at the lingual side only; 2, 3, 4. the forces of 0.490, 0.735 and 0.980 N loaded at both buccal and lingual sides, respectively.) were included. The initial displacements of the lower second molar and stress distribution in the periodontal ligaments were analyzed. Results: More uniform stress distributions in the periodontal membrane of mandibular left second molar were found when the mesial force were loaded at both buccal and lingual sides than the force loaded at lingual side only. More inclination of the second molar was observed when force loaded at both sides than at lingual side only. With the values of the force increased, the mesial inclination potential of the second molar, the initial movement of the second molar and the stress distribution in the periodontal membrane increased. Under the force of 0.735 N at both buccal and lingual sides, mesially inclined initial displacements of the mandibuar second molar were observed and the stress values of von Mises was in the suitable area. Conclusions: Less second molar rotation was found when the force loaded at both buccal and lingual sides than loaded at lingual side only. However, force loaded at both sides would increase the measial inclination potential of the second molar.

Abstract
Objective: To investigate the expressions of Fra-1 and HMGA1 in laryngeal squamous cell carcinoma and their correlation. Methods: Immunohistochemistry and reverse transcription-polymer chain reaction (RT-PCR) were used to detect the expressions of HMGA1 and Fra-1 in laryngeal squamous carcinoma tissues in 47 cases and para-carcinoma tissues in 21 cases(the First Hospital of Shijiazhuang). The relationship between the gene expressions in carcinoma tissues and clinopathological parameters such as pathological grade, clinical stage, lymph metastasis, age and anatomic site and the relevance of the two gene expressions were analyzed. SPSS 13.0 software was used to analyze the data. Results: The positive expression rates of Fra-1 and HMGA1 proteins in laryngeal squamous cancer tissue were 48.9% and 53.2%, which were respectively higher than the rates of 19.0% for Fra-1 (χ(2)=5.416, P<0.05) and of 23.8% for HMGA1 (χ(2)=5.083, P<0.05) in adjacent tissues. The expression of Fra-1 gene was correlation with pathological grade, clinical stage and lymph metastasis (t values were -1.079, -1.066 and -1.067, all P<0.05), but not with age and anatomic site (t values were -1.068 and -1.054, both P>0.05). The expression of HMGA1 gene was correlation with pathological grade, clinical stage, lymph metastasis and age (t values were -1.112, -1.065, -1.009 and -1.066, all P<0.05), but not with anatomic site (t=-1.036, P>0.05). The expressions of Fra-1 and HMGA1 gene were positively correlation (r=0.672, P<0.05). Conclusions: In laryngeal squamous cancer, Fra-1 and HMGA1 are excessive expression, with a positive correlation between the expressions of both genes.

Abstract
Objective: To evaluate the effectiveness and safety of anti-fibrinolytic therapy in on-pump coronary artery bypass grafting (CABG). Methods: Two hundred and eleven patients receiving on-pump CABG in Fuwai Hospital were recruited and randomized into treatment group (group T) and control group (group C) between October 2014 and February 2017. Tranexamic acid was given with a 10 mg/kg loading dose and 10 mg·kg(-1)·h(-1) infusion dose to group T and equal volume of saline was given to group C throughout the surgery. Postoperative drainage, allogeneic transfusion, complications, adverse events and mortality were recorded. Results: Patients of group T had less postoperative drainage [860 (670, 1 190)ml vs 985 (783, 1 365)ml], decreased red blood cell [2 (0, 8)U vs 6 (2, 10)U] and fresh frozen plasma [1 (0, 3) U vs 2 (0, 3)U] transfusion volume, lower fresh frozen plasma transfusion rate (53.33% vs 70.75%) than patients of group C (all P<0.05). No statistically significant differences existed in the rate of postoperative complications, adverse events and death between the two groups (all P>0.05). Conclusion: Tranexamic acid has definite anti-fibrinolytic effect, which can significantly reduce postoperative bleeding and allogeneic transfusion while no severe side effects were observed.

Abstract
Objective: To explore the training pattern of periodontal probing practice so as to improve the accuracy of probing depth measurements of undergraduate students. Methods: Sixty-two undergraduate dental students in their pre-clinical training course were divided into two groups (31 students in each group): the reform group and the control group. The students in reform group learned and practiced periodontal probing by using transparent gingiva models for 30 minutes, and using conventional periodontal probing models for further 90 minutes in two sessions. The total practicing time was 2 hours. The students in control group learned and practiced periodontal probing using conventional periodontal probing models only for 1 hour of practicing time. After the training, new conventional periodontal probing models were used to evaluate the accuracy of probing depth measurements of the students in the two groups. The probing depths of Ramfjord index teeth were recorded by the students and were compared with the results of an experienced teacher's measurements. Results: The percentage of absolutely consistent sites in the reform group (63.4% [708/1 116]) was significantly higher than that of the control group (60.0% [670/1 116]) (P=0.012). In both reform group and control group, the percentages of absolutely consistent sites of the incisors (reform group: 69.1% [257/372], control group: 65.9% [245/372]) were significantly higher than those of the molars (reform group 58.9% [219/372], control group 54.3% [202/372])(P< 0.01), meanwhile, the percentages of absolutely consistent sites of the buccal-lingual sites (reform group: 88.7% [330/372], control group: 80.4% [299/372]) were significantly higher than those of the interproximal sites (reform group: 50.8% [378/744], control group: 49.9% [371/744])(P<0.01). Conclusions: The comprehensive reform of periodontal probing training could improve the accuracy of probing depth measurement of the undergraduate students. During the pre-clinical practice, probing training in the molar areas and the interproximal sites should be reinforced.

Abstract
In recent years, there are increasing articles concerning Epstein-Barr virus associated lymphoproliferative disorder (EBV+ LPD), and the name of EBV+ LPD is used widely. However, the meaning of EBV+ LPD used is not the same, which triggered confusion of the understanding and obstacles of the communication. In order to solve this problem. Literature was reviewed with combination of our cases to clarify the concept of EBV+ LPD and to expound our understanding about it. In general, it is currently accepted that EBV+ LPD refers to a spectrum of lymphoid tissue diseases with EBV infection, including hyperplasia, borderline lesions, and neoplastic diseases. According to this concept, EBV+ LPD should not include infectious mononucleosis (IM) and severe acute EBV infection (EBV+ hemophagocytic lymphohistiocytosis, fatal IM, fulminant IM, fulminant T-cell LPD), and should not include the explicitly named EBV+ lymphomas (such as extranodal NK/T cell lymphoma, aggressive NK cell leukemia, Burkitt lymphoma, and Hodgkin lymphoma, etc.) either. EBV+ LPD should currently include: (1) EBV+ B cell-LPD: lymphomatoid granulomatosis, EBV + immunodeficiency related LPD, chronic active EBV infection-B cell type, senile EBV+ LPD, etc. (2) EBV+ T/NK cell-LPD: CAEBV-T/NK cell type, hydroa vacciniforme, hypersensitivity of mosquito bite, etc. In addition, EBV+ LPD is classified, based on the disease process, pathological and molecular data, as 3 grades: grade1, hyperplasia (polymorphic lesions with polyclonal cells); grade 2, borderline (polymorphic lesions with clonality); grade 3, neoplasm (monomorphic lesions with clonality). There are overlaps between EBV+ LPD and typical hyperplasia, as well as EBV+ LPD and typical lymphomas. However, the most important tasks are clinical vigilance, early identification of potential severe complications, and treating the patients in a timely manner to avoid serious complications, as well as the active treatment to save lives when the complications happened.

Abstract
Objective:To investigate expressions of Fra-1 in laryngeal squamous cell carcinoma. Method:Using immunohistochemical method and RT-PCR detecting 47 cases of laryngeal squamous carcinoma tissues and 21 cases of para-carcinoma tissues with the level of protein and mRNA, we analyzed the relationship of the genes expression and clinical parameters. Result:The level of protein positive expression of Fra-1 genes in laryngeal squamous cancer tissue were higher than adiacent tissues (P<0.05). The expression of Fra-1 protein in laryngeal squamous cancer tissue were significant correlation with the clinical stages, lymph metastasis, smoking. They had no significant correlation with the pathological grade, age, anatomic zonation. The mRNA level expression of Fra-1 genes in laryngeal squamous cancer tissue were higher than adjacent tissues (P<0.01). The expression of Fra-1 gene in the mRNA level was correlated with pathologic stage, clinical stage, lymph metastasis, and smoking, but wasn't correlated with age and anatomic zonation. Conclusion:In laryngeal squamous cell carcinoma, the expression of Fra-1 gene are overexpressed. Fra-1 may play a role in the occurrence and development of the laryngeal cancer.

Abstract
Objective: To analyze the level of immunoglobulin E (IgE) changes with benzene exposure workers. Methods: Firstly, through occupational health monitoring, 68 hospitalized cases were discovered who were suspected chronic benzene poisoning. Secondly, according to the GBZ68-2013《The diagnosis of occupational benzene poisoning》standard diagnosis and indexing, 68 cases were divided into the benzene poisoning group (n= 29) and the benzene exposure group (n=39) . 50 cases of healthy workers without benzene exposure were for the control group. Use the immune luminescence method to detect IgE levels. Thirdly, Case-control study was used, observing IgE changes though the three groups by statistical analysis. Results: Compared with control group, the level of leukocyte、neutrophil and IgE was drop in benzene exposure group with statistically significant (P<0.05) . Compared with benzene exposure group, IgE of benzene poisoning group was rise, with statistically significant (P<0.05) , IgE of mild benzene poisoning group rise the most obvious, with statistically significant (P<0.05) . Compared with benzene exposure group, IgE of moderate benzene poisoning group was drop, without statistically significant (P>0.05) . Conclusion: Benzene occupational exposure can induce immunosuppression, IgE decreases, and reduces immune surveillance. The response of the IgE level in the mild benzene poisoning patients was significantly elevated, whether it is protective response of the body immune function needs to be studied further investigated.

Abstract
Objective: To determine the diagnostic value of serum cystatin C (Cys C) for acute kidney injury (AKI) in patients with liver cirrhosis. Methods: Serum Cys C levels in 150 liver cirrhosis patients (88 AKI and 62 non-AKI patients) were measured by the Particle-Enhanced Nephelometric Immuno-Assay. The accuracy of serum Cys C for the diagnosis of AKI in liver cirrhosis was evaluated by the ROC curve. Results: Liver cirrhosis patients with AKI had significantly higher serum Cys C levels [2.37 (1.75-2.83) mg/L] than those without AKI [0.97 (0.85-1.09) g/L] (P <0.001). Serum Cys C level was highest in the acute tubular necrosis group [5.41 (2.77-6.19) mg/L], followed by the hepatorenal syndrome group [2.55 (2.28-3.59) mg/L] and prerenal azotemia group [2.07 (1.70-2.41) mg/L], and the serum Cys C level was significantly different between the three groups (P <0.001). In addition, patients with AKI were further divided into infection group and non-infection group. Serum Cys C level was significantly higher in the infection group than in the non-infection group (P <0.05). The area under the ROC curve of serum Cys C for the diagnosis of AKI in liver cirrhosis was 0.99 (0.98-1.00) at a cut-off value of 1.36 mg/L, and the sensitivity and specificity were 97% and 95%, respectively. Conclusion: Serum Cys C is a good marker for detecting AKI in liver cirrhosis, and the different levels of increase in Cys C may be useful in differentiating the different types of AKI.

Abstract
PURPOSE To analyze the role of geniposide in the protein degradation of Txnip and to determine the impact of Txnip on geniposide-regulated GSIS in pancreatic INS-1 cells. METHODS The content of Txnip protein was measured by western blot; insulin content and glucose uptake were determined by ELISA; and knockdown of Txnip was the method of RNA interference. RESULTS Glucose induces a rapid increase in Txnip protein, and geniposide accelerates the degradation of Txnip via proteasome pathway in the presence of high glucose (25 mM) in INS-1 pancreatic β-cells. And MG132, a proteasomal inhibitor, potentiates glucose uptake, metabolism (ATP production) and glucose-stimulated insulin secretion (GSIS) in high-glucose (25 mM)-treated INS-1 cells, but geniposide significantly prevents these effects. Furthermore, the combination of geniposide and Txnip knockdown shows substantial synergistic effects to reduce glucose uptake, metabolism and GSIS in high-glucose (25 mM)-treated INS-1 cells. CONCLUSIONS Txnip protein played an essential role in glucose uptake, metabolism and GSIS, and geniposide could accelerate the degradation via proteasome pathway in high-glucose-treated pancreatic INS-1 cells.
