Abstract
BACKGROUND There are significant correlations between the levels of tumor infiltrating lymphocytes (TILs) and the prognosis of primary breast cancer. While little is known about immunological mechanisms in the distant metastasis of advanced breast cancer. PATIENTS AND METHODS A total of 106 patients with advanced metastatic breast cancer were enrolled in this study between 2016 and 2022. Hematoxylin and eosin staining and immunohistochemistry were used to assess the densities of stromal TILs (sTILs), intratumoral TILs (iTILs) and invasive marginal TILs (imTILs) and CD4+, CD8+, CD20+, FOXP3+ TILs in the primary tumor and metastasis (bone, lung, liver, and distant lymph node) of advanced breast cancer. RESULTS Higher levels of sTILs at metastatic sites were associated with better progression-free survival (PFS), postmetastasis survival (PMS) and overall survival (OS) (p = .026, .001 and .005, respectively). The levels of iTILs were significantly lower than those of sTILs and imTILs in both primary tumor (p< .001, both) and metastasis (p< .001, both). The level of CD4+ T cells was higher than those of CD8+ T cells and CD20+ B cells in both primary tumor (p < .001) and metastasis (p < .001). The levels of sTILs (p=0. 001) and imTILs (p< .001) in the primary tumor were generally higher than those in the metastasis. CONCLUSION The levels of TILs and their subsets can predict the survival and prognosis of patients with advanced breast cancer. The distributions of TILs and their subsets are similar between the primary tumor and metastasis. The metastases have a lower degree of lymphocytes infiltration than its corresponding primary tumor.

Abstract
Low-tannin sorghum is an excellent energy source in pig diets. However, sorghum contains several anti-nutritional factors that may have negative effects on nutrient digestibility. The impacts of proteases on growth performance, nutrient digestibility, blood parameters, and gut microbiota of growing pigs fed sorghum-based diets were studied in this study. Ninety-six pigs (20.66 ± 0.65 kg BW) were allocated into three groups (eight pens/group, four pigs/pen): (1) CON (control diet, sorghum-based diet included 66.98% sorghum), (2) PRO1 (CON + 200 mg/kg proteases), (3) PRO2 (CON + 400 mg/kg proteases) for 28 d. No differences were observed in growth performance and apparent total tract digestibility (ATTD) of nutrients between CON and PRO1 groups. Pigs fed PRO2 diet had increased (P < 0.05) BW on d 21 and 28, and increased (P < 0.05) average daily gain during d 14-21 and the overall period compared with pigs fed CON diet. In addition, pigs fed PRO2 diet had improved (P < 0.05) ATTD of gross energy, CP, and DM compared with pigs fed CON and PRO1 diets. Pigs fed PRO2 diet had lower (P < 0.05) plasma globulin (GLB) level and higher (P < 0.05) plasma glucose, albumin (ALB) and immunoglobulin G levels, and ALB/GLB ratio than pigs fed CON and PRO1 diets. Furthermore, pigs fed PRO2 diet had decreased (P < 0.05) the relative abundance of Acidobacteriota at the phylum level and increased (P < 0.05) the relative abundance of Prevotella_9 at the genus level. The linear discriminant analysis effect size analysis also showed that pigs fed PRO2 diet had significantly enriched short-chain fatty acid-producing bacteria, such as Subdoligranulum and Parabacteroides. In conclusion, protease supplementation at 400 mg/kg improved the growth performance of growing pigs fed sorghum-based diets, which may be attributed to the improvement of nutrient digestibility, host metabolism, immune status and associated with the altered gut microbiota profiles.

Abstract
Objective: To summarize the management and short-term outcomes of neonates delivered by mothers infected with SARS-CoV-2 Omicron variant. Methods: A retrospective study was performed on 158 neonates born to mothers infected with SARS-CoV-2 Omicron variant admitted to the isolation ward of Children's Hospital of Fudan University from March 15th, 2022 to May 30th, 2022. The postnatal infection control measures for these neonates, and their clinical characteristics and short-term outcomes were analyzed. They were divided into maternal symptomatic group and maternal asymptomatic group according to whether their mothers had SARS-CoV-2 symptoms. The clinical outcomes were compared between the 2 groups using Rank sum test and Chi-square test. Results: All neonates were under strict infection control measures at birth and after birth. Of the 158 neonates, 75 (47.5%) were male. The gestational age was (38+3±1+3) weeks and the birth weight was (3 201±463)g. Of the neonates included, ten were preterm (6.3%) and the minimum gestational age was 30+1 weeks. Six neonates (3.8%) had respiratory difficulty and 4 of them were premature and required mechanical ventilation. All 158 neonates were tested negative for SARS-COV-2 nucleic acid by daily nasal swabs for the first 7 days. A total of 156 mothers (2 cases of twin pregnancy) infected with SARS-CoV-2 Omicron variant, the time from confirmed SARS-CoV-2 infection to delivery was 7 (3, 12) days. Among them, 88 cases (56.4%) showed clinical symptoms, but none needed intensive care treatment. The peripheral white blood cell count of the neonates in maternal symptomatic group was significantly higher than that in maternal symptomatic group (23.0 (18.7, 28.0) × 109 vs. 19.6 (15.4, 36.6) × 109/L, Z=2.44, P<0.05). Conclusions: Neonates of mothers infected with SARS-CoV-2 Omicron variant during third trimester have benign short-term outcomes, without intrauterine infection through vertical transmission. Strict infection control measures at birth and after birth can effectively protect these neonates from SARS-CoV-2 infection.

Abstract
Objective: To explore the value of metagenomic next-generation sequencing (mNGS) in the etiology diagnosis of bacterial meningitis in children. Methods: The etiological results of 189 children diagnosed with "bacterial meningitis" or "purulent meningitis" or "central nervous system infection" in the Children's Hospital of Fudan University from 1st January 2019 to 31st December 2020 were analyzed retrospectively. The cerebrospinal fluid (CFS) of the children with bacterial meningitis was detected by culture and mNGS respectively, and the difference of pathogen detection rate between the 2 methods was analyzed. According to the age at the time of visit, the children were divided into neonatal group (≤28 days of age) and non-neonatal group (>28 days of age), and χ2 test was used to compare the positive rate between the 2 groups. Taking CFS culture as the gold standard, the sensitivity and specificity of mNGS in the diagnosing of bacterial meningitis in children were analyzed. Results: Among these 189 children with bacterial meningitis, 116 were males and 73 were females. A total of 76 strains of pathogens were detected in blood and (or) CSF cultures, of which 50 strains (65.8%) were Gram-positive bacteria; among those, 18 strains (23.7%) of Streptococcus agalactiae, 17 strains (19.7%) of Escherichia coli and 15 strains (19.7%) of Streptococcus pneumoniae were detected with higher detection rate. The infection rate of Gram-positive bacteria in the non-neonatal group was higher than that in the neonatal group (76.0% (38/50) vs. 50.0% (13/26), χ2=5.24, P=0.020).The same CSF samples of 48 cases were tested by mNGS and culture at the same time, and the detection rate of mNGS was higher than that of CSF culture (20 cases (41.7%) vs. 12 cases (25.0%), χ2=16.45, P<0.001). The consistency of mNGS and culture results was 79.2% (38/48), and the same pathogen was detected in 11 children with both positive mNGS and CSF culture. Taking the results of CSF culture as the gold standard, the sensitivity of mNGS in the diagnosing of bacterial meningitis was 91.7%, and the specificity was 75.0%. Conclusions: The mNGS technology can improve the pathogen detection rate of bacterial meningitis in children, and has a high consistency with CSF culture. In suspected cases where the pathogen cannot be identified by traditional methods, CSF mNGS should be considered timely.

Abstract
AIM To determine the differences in clinicopathological and mammographic findings between ductal carcinoma in situ (DCIS) and ductal carcinoma in situ with micro-invasion (DCIS-MI) and explore clinicopathological and mammographic factors associated with DCIS-MI. MATERIALS AND METHODS All DCIS patients with or without micro-invasion who underwent preoperative mammography at The Affiliated Hospital of Qingdao University from January 2016 through June 2020 were identified retrospectively. The correlations of clinicopathological findings with DCIS-MI were evaluated using univariate and multivariate binary logistic regression analyses. Imaging findings were compared between the groups by using the Pearson chi-square test. RESULTS A total of 445 DCIS lesions and 151 DCIS-MI lesions were included in the final analysis. Large extent (≥2.7 cm), high nuclear grade, comedo-type, negative progesterone receptor (PR), negative oestrogen receptor (ER), high Ki-67 and axillary lymph node metastasis were more frequently found in DCIS-MI than in DCIS (all p<0.05), and the first four of these were found to be independent predictors of DCIS-MI in the multivariate analysis (all p<0.05). Regarding imaging findings, compared to DCIS, DCIS-MI showed fewer occult lesions and more lesions with calcifications in mass, asymmetry, and architectural distortion (p=0.004). Grouped calcifications were usually associated with DCIS, while regional calcifications were commonly found in DCIS-MI (p<0.05). CONCLUSION Large extent, high nuclear grade, comedo-type and negative PR were found to be independent predictors of DCIS-MI. Lesions with calcifications and regional calcifications were more likely associated with DCIS-MI on mammography.

Abstract
Objective: To investigate the clinical characteristics of pediatric methicillin-resistant Staphylococcus aureus (MRSA) infection and the antibiotic sensitivity of the isolates. Methods: The clinical data of children with MRSA infection and antibiotic sensitivity of the isolates from 11 children's hospitals in Infectious Diseases Surveillance of Paediatrics (ISPED) group of China between January 1, 2018 and December 31, 2018 were collected retrospectively. The children's general condition, high-risk factors, antimicrobial therapy and prognosis, differences in clinical disease and laboratory test results between different age groups, and differences of antibiotic sensitivity between community-acquired (CA)-MRSA and hospital-acquired (HA)-MRSA were analyzed. The t test and Wilcoxon rank sum test were used for statistical analysis of the quantitative data and Chi-square test were used for comparison of rates. Results: Among the 452 patients, 264 were males and 188 were females, aged from 2 days to 17 years. There were 233 cases (51.5%) in the ≤1 year old group, 79 cases (17.5%) in the>1-3 years old group, 29 cases (6.4%) in the >3-5 years old group, 65 cases (14.4%) in the >5-10 years old group, and 46 cases (10.2%) in the>10 years old group. The main distributions of onset seasons were 55 cases (12.2%) in December, 47 cases (10.4%) in February, 46 cases (10.2%) in November, 45 cases (10.0%) in January, 40 cases (8.8%) in March. There were 335 cases (74.1%) CA-MRSA and 117 (25.9%) cases HA-MRSA. Among all cases, 174 cases (38.5%) had basic diseases or long-term use of hormone and immunosuppressive drugs. During the period of hospitalization, 209 cases (46.2%) received medical interventions. There were 182 patients (40.3%) had used antibiotics (β-lactams, glycopeptides, macrolides, carbapenems, oxazolones, sulfonamides etc) 3 months before admission. The most common clinical disease was pneumonia (203 cases), followed by skin soft-tissue infection (133 cases), sepsis (92 cases), deep tissue abscess (42 cases), osteomyelitis (40 cases), and septic arthritis (26 cases), suppurative meningitis (10 cases). The proportion of pneumonia in the ≤1 year old group was higher than the >1-3 years old group,>3-5 years old group,>5-10 years old group,>10 years old group (57.5% (134/233) vs. 30.4% (24/79), 31.0% (9/29), 38.5% (25/65), 23.9% (11/46), χ(2)=17.374, 7.293, 7.410, 17.373, all P<0.01) The proportion of skin and soft tissue infections caused by CA-MRSA infection was higher than HA-MRSA (33.4% (112/335) vs. 17.9% (21/117), χ(2)=10.010, P=0.002), and the proportion of pneumonia caused by HA-MRSA infection was higher than CA-MRSA (53.0% (62/117) vs. 42.1% (141/335), χ(2)=4.166, P=0.041). The first white blood cell count of the ≤1 year old group was higher than that children > 1 year old ((15±8)×10(9)/L vs. (13±7)×10(9)/L, t=2.697, P=0.007), while the C-reactive protein of the ≤1 year old group was lower than the 1-3 years old group,>5-10 years old group,>10 years old group (8.00 (0.04-194.00) vs.17.00 (0.50-316.00), 15.20 (0.23-312.00), 21.79(0.13-219.00) mg/L, Z=3.207, 2.044, 2.513, all P<0.05), there were no significant differences in procalcitonin (PCT) between different age groups (all P>0.05). After the treatment, 131 cases were cured, 278 cases were improved, 21 cases were not cured, 12 cases died, and 10 cases were abandoned. The 452 MRSA isolates were all sensitive to vancomycin (100.0%), linezolid (100.0%), 100.0% resistant to penicillin, highly resistant to erythromycin (85.0%, 375/441), clindamycin (67.7%, 294/434), less resistant to sulfonamides (5.9%, 23/391), levofloxacin (4.5%, 19/423), gentamicin (3.2%, 14/438), rifampicin (1.8%, 8/440), minocycline (1.1%, 1/91). The antimicrobial resistance rates were not significantly different between the CA-MRSA and HA-MRSA groups (all P>0.05). Conclusions: The infection of MRSA is mainly found in infants under 3 years old. The prevalent seasons are winter and spring, and MRSA is mainly acquired in the community. The main clinical diseases are pneumonia, skin soft-tissue infection and sepsis. No MRSA isolate is resistant to vancomycin, linezolid. MRSA isolates are generally sensitive to sulfonamides, levofloxacin, gentamicin, rifampicin, minocycline, and were highly resistant to erythromycin and clindamycin. To achieve better prognosis. clinicians should initiate anti-infective treatment for children with MRSA infection according to the clinical characteristics of patients and drug sensitivity of the isolates timely and effectively.

Abstract
Talent training is the core and foundation of public health system construction. Shortage of talents in the field of disease prevention and public health exposed by COVID-19 pandemic highlights the importance of developing preventive medical education. This article analyzes the challenges of medical education in the dilemma of "separation of medical treatment and prevention", and the new requirements for preventive medical education in the construction of New Medicine under the Healthy China strategy. Four aspects including stepping up the resource allocation and investment, educating responsible public health professionals, the education of all medical students who implement the core competence of public health, and the establishment of a continuing education system for preventive medicine have been considered. A series of specific suggestions are put forward including the establishment of a full-chain closed-loop research system to support the cultivation of top-notch innovative public health talents, strengthening the assessment of core public health capabilities for clinical medical professional admission, formulating a "medical and preventive integration" training program for primary health personnel, and implementing "combination of peace and war" public health personnel reserve system, with the purpose of providing reference for the reform and development of preventive medical education in China.

Abstract
Objective: To investigate the expression and clinicopathological significance of high mobility group box protein B1 (HMGB1) protein in breast cancer. Methods: The expression of HMGB1 protein in 26 normal breast tissues and 417 invasive breast cancer tissues diagnosed at Dongyang People's Hospital, Zhejiang Province from 2016 to 2018 were detected by immunohistochemical EnVision method. The relationship between nuclear and cytoplasmic HMGB1 protein expression and clinicopathologic features of breast cancer patients were analyzed. Results: The nuclear and cytoplasmic expression of HMGB1 protein was 80.8% (337/417) and 16.8% (70/417) respectively in breast cancer, and was 46.2%(12/26) and 0(0/26) respectively in normal breast tissue. Both nuclear and cytoplasmic expression of HMGB1 protein in breast cancer were significantly higher than normal breast tissue (P<0.001, P=0.046, respectively). The nuclear expression of HMGB1 protein was also higher in high grade, estrogen receptor (ER) negative, progesterone receptor (PR) negative (P=0.006, P=0.004, P<0.001, respectively); whereas the cytoplasmic expression of HMGB1 protein was also higher in high grade, estrogen receptor (ER) negative, progesterone receptor (PR) negative (P<0.001 in all) breast cancers. Multivariate logistic regression model showed that nuclear HMGB1 expression correlated with histologic grade (OR=2.188, 95%CI=1.078-4.443, P=0.030), while cytoplasmic HMGB1 expression correlated with histologic grade (OR=3.031, 95%CI=1.600-5.742, P=0.001), ER (OR=0.129, 95%CI=0.034-0.494, P=0.003) and TNM staging (OR=3.820, 95%CI=1.042-14.001, P=0.043). Multivariate analysis of Cox proportional hazard model showed that nuclear HMGB1 expression was an independent risk factor for the overall survival of breast cancer patients (HR=0.366, 95%CI=0.138-0.972, P=0.044). Conclusion: Nuclear and cytoplasmic HMGB1 proteins are related to multiple poor prognostic factors in breast cancer, and may be a potential biomarker for breast cancer treatment.

Abstract
Objective: To investigate the prevalence and resistance changes of carbapenem-resistant Enterobacteriaceae (CRE) strains isolated from children patients of Chinese Bacterial Resistance Surveillance Network (CHINET) from 2005 to 2017. Methods: Antimicrobial susceptibility testing was carried out by disk diffusion method (KB method) and automated systems. Results were analyzed according to the Clinical and Laboratory Standards Institute (CLSI) 2017 edition standards. Results: Among the 4 481 CRE clinical strains, the overall prevalence of CRE in children was 6.4%, including 8.8% in neonatal period, 7.3% in infancy, 3.8% in early childhood, 4.0% in preschool, 4.7% at school age and 7.4% of puberty. The CRE prevalence of citrobacter spp. remained stable in 2005-2017, whereas other bacteria showed an upward trend, which was higher than that of the adult group (P<0.01). Among the 4 481 CRE strains, there were 2 905 strains of Klebsiella spp. (64.8%), 813 strains of Escherichia coli (18.1%), 549 strains of Enterobacter spp.(12.3%), and 65 strains of Citrobacter spp.(1.5%). Among the 4 481 CRE strains, 20.7%, 13.3%, and 11.8% were from the intensive care unit (ICU), neonatal department and internal medicine wards, respectively. Specimens were distributed as respiratory (42.8%), urine (26.3%), and blood (14.9%). The results of antimicrobial susceptibility testing exhibited that the CRE strains were highly resistant to most commonly used antimicrobial agents in clinical practice, such as imipenem, meropenem and ertapenem, as well as penicillins and cephalosporins, etc. Conclusion: The prevalence of CRE strains in children is increasing year by year, and their antimicrobial resistance to common antibacterial agents in clinical practice is extremely serious, to which serious attention needs to be paid. According to the results of antimicrobial susceptibility testings, the antibacterial agents should be rationally selected to effectively control the spread of CRE.

Abstract
Objective: To improve the understanding of clinical characteristics of streptococcal toxic shock syndrome (STSS) caused by Streptococcus pyogenes (S. pyogenes) in children. Methods: A retrospective study was conducted to analyze the clinical data of STSS caused by S. pyogenes (culture-confirmed) in 7 tertiary hospitals during 2010-2017 in China. Clinical and laboratory data were collected by reviewing the medical records. Results: Fifteen cases of STSS, including 9 males, were confirmed and the ages of the patients ranged from 6 months to 15 years, with median age of 3 years. All cases had the positive blood culture for S. pyogenes and only 3 cases had short course of β-lactam treatment before blood culture. Medical evaluation was initiated within (5.1±4.6) days after symptom onset. All patients had fever, and 13 patients had multiple organ dysfunction and 10 patients had disseminated intravascular coagulationl (DIC). Twelve cases had severe pneumonia with or without skin and (or) soft tissue infections. Underlying conditions included giant hemangioma of the skin in 2 patients and varicella in 1 patient. All isolated strains in 14 cases were sensitive to penicillin G, ceftriaxone/cefotaxime, vancomycin, but 12 and 13 isolates were resistant to clindamycin and erythromycin, respectively. Eight patients died, and 5 of them died within 24 hours after admission. One patient was lost to follow-up after intended discharge against medical advice. Conclusion: STSS caused by S. pyogenes in children is a severe syndrome with rapid clinical progression and high mortality rate, and thus the pediatricians should be aware of STSS and immediately initiate aggressive treatment for the suspected cases.

Abstract
Objective: To study the correlations between the distance stereoacuity and the levels of control at different far distance fixations in children with intermittent exotropia. Methods: In this prospective, non-interventional case series study, 52 children with intermittent exotropia (basic, divergence excess and pseudo-divergence excess types, exodeviation angles≥15 PD) admitted to the Shandong Provincial Hospital Affiliated to Shandong University for surgery between August 2014 and March 2015 were enrolled. The distance stereoacuity was tested with the distance Randot stereotest, and the control of exodeviation was assessed at outdoor far distance fixation of 50 m, indoor far distance fixation of 30 m, and indoor distance fixation of 3 m, respectively, using the office-based 6-point control scale proposed by Mohney and Holmes. The distance stereoacuity and control scores of every intermittent exotropia child were tested 3-4 times in a single day with an interval of at least 2 hours. Nonparametric Spearman rank method was used to analyze the correlations between distance stereoacuity and levels of control at three different far distances in children with intermittent exotropia. Results: The mean age of 52 enrolled children (26 males, 26 females) was 7 years (range, 5-12 years), and 192 groups of distance stereoacuity and control scores were got for the 52 children. Positive correlations between the distance stereoacuity and the levels of control at outdoor far distance fixation of 50 m, indoor far distance fixation of 30 m, and indoor distance fixation of 3 m were observed (coefficients of correlations; r=0.489, 0.472, 0.282, all P<0.001). Conclusion: There are correlations between the distance stereoacuity and the levels of control at outdoor far distance fixation of 50 m, indoor far distance fixation of 30 m and indoor distance fixation of 3 m in children with intermittent exotropia, and the former two are found to be stronger than the latter one.

Abstract
Nasal leukoplakia, defined as nasal mucosal grayish white lesion accompanied by adjacent mucosa thickening and hyperemia, is a kind of precancerous lesion. Since a case of nasal septum mucosal leukoplakia reported by Edley in 1955 and 62 cases of nasal leukoplakia reported by Liu Chun-Lin in 1964, few cases were reported. In this review, the pathogenesis, diagnosis and treatment of nasal mucosal leukoplakia are systematically summarized. Attention should be paid to this disease to reduce the possibility of incidence of malignant tumors.

Abstract
Objective: To describe the clinical characteristics of pneumococcal infections and drug resistance of Streptococcus pneumoniae isolates from children's hospitals, which would provide reference for preventing and treating pneumococcal diseases. Methods: This was a prevalence survey. In this study, the age, specimen type, monthly distribution characteristics, and antimicrobial resistance of Streptococcus pneumoniae isolates from 9 children's hospitals in China were investigated between January 1, 2016 and December 31, 2016. The WHONET 5.6 software was used to analyze the antibiotic susceptibility of Streptococcus pneumoniae. The comparison of rates was performed by Chi-square test. Results: A total of 6 200 isolates of streptococcus pneumoniae were obtained, namely, 95.1% (5 876/6 177) from the respiratory tract specimens, 2.2% (136/6 177) from blood specimens and 0.4% (24/6 177) from cerebrospinal fluid specimens. The isolates were mainly from children older than 1 and younger than 5 years (54.7%, 3 381/6 185) . Most of strains (33.2%, 1 184/3 563) were isolated in November, December and January. Streptococcus pneumoniae isolates were completely sensitive to vancomycin (100.0%, 6 189/6 189) , linezolid (100.0%, 6 030/6 030) , moxifloxacin (100.0%, 3 064/3 064) , highly sensitive to levofloxacin (99.8%, 5 528/5 540), ertapenem (98.8%, 3 024/3 061) and lowly sensitive to erythromycin (1.7%, 102/6 016), clindamycin (3.7%, 116/3 136), and tetracycline (5%, 244/4 877), respectively. According to the parenteral susceptibility breakpoints for non-meningitis isolates, the sensitivity of Streptocococus pneumoniae to penicillin from children's hospital of Chongqing Medical University (49.3%, 892/1 809) was significantly lower than those of other hospitals (χ(2)=1 268.161, P<0.05) . Conclusions:Streptococcus pneumoniae is mainly isolated from respiratory tract, from children older than 1 and younger than 5 years and during November to January in tertiary children's hospital of China. The Streptococcus pneumoniae from children is highly sensitive to vancomycin, linezolid, moxifloxacin, levofloxacin. There are also significant differences in the sensitivity of penicillin for Streptococcus pneumoniae from different hospitals.

Abstract
The objective of this study was to determine the effects of feeding sodium stearoyl-2-lactylate (SSL) as a new feeding emulsifier diet with and without soybean oil (SO) on the milk fat globule (MFG) size, milk composition, digestibility of nutrients, and performance in lactating sows. Sixty sows (Large White × Landrace) were randomly assigned to 1 of 4 treatments according to a 2 × 2 factorial arrangement of treatments. Each treatment had 15 replicates composed of 1 sow. The factors included 1) the fat level (0% vs. 3% SO) and 2) the emulsifier content (0% vs. 0.1% SSL). Treatments included 1) Control (without SO and SSL), 2) SO (3% SO without SSL), 3) SSL (0.1% SSL without SO), and 4) SO + SSL (3% SO and 0.1% SSL). During the suckling period, sows in the SO + SSL group lost less back fat thickness ( < 0.05) compared to other groups; sows fed 3% SO diets consumed less feed ( < 0.05) compared to sows fed diets without SO, but there were no significant effects ( > 0.05) of dietary fat and its interaction with a dietary emulsifier on energy intake and the weaning-estrus interval. The digestibility of ether extract in the SO + SSL group was greater than in the SO group ( < 0.05). Moreover, greater digestibility of CP, Ca, and P in the SO+SSL group was observed compared to that of other groups ( < 0.05). Feeding the SO + SSL diet improved the concentrations of milk fat, protein, and total solids on d 11 of lactation compared to other diets ( < 0.05). Also, an interaction between supplemental SSL and SO was observed for the milk fat and total solids concentrations. The average diameter of MFG on d 11 of lactation was significantly decreased by the addition of 0.1% SSL compared to a diet with no SSL supplementation ( < 0.05). No significant differences among the dietary treatments were observed in cholesterol, triglyceride, high-density lipoprotein cholesterol, or low-density lipoprotein cholesterol in sows' plasma ( > 0.05). In conclusion, feeding a 0.1% SSL diet to lactating sows may decrease the average diameter of MFG and improve the digestibility of nutrients and composition of milk.

Abstract
OBJECTIVE To analyze the clinical characteristics of blood stream infection caused by Streptococcus agalactiae in children and the drug-resistance of the isolates. METHOD All cases with Streptococcus agalactiae growth in blood or cerebrospinal fluid cultures from January 1, 2011 to December 31, 2015 were enrolled by checking the laboratory information system (LIS) from 7 Class 3 Grade A hospitals (4 in Zhejiang, 2 in Shanghai and 1 in Chongqing). Clinical data were collected for analysis. χ(2) test, t test and non parametric test were used in the study. RESULT One hundred and eighty-one pediatric cases of blood stream infection caused by Streptococcus agalactiae were included in current study. Eighty-six cases (47.5%) were male, and with age range from one day to 9 years (media 13 days). Thirty cases (16.6%) were premature infants and 127 cases (70.2%) were born via vaginal delivery. Seventy-one cases (39.2%) had early onset (<7 d) infections, and 106 cases (58.6%) had late onset (7-89 d) infections. Seventy-eight cases (43.1%) were complicated with purulent meningitis. Incidences of vaginal delivery(81.7%(58/71) vs. 62.3%(66/106)), shortness of breath moaning (43.7%(31/71) vs. 15.1%(16/106)) and preterm premature rupture of membranes (25.4%(18/71) vs. 3.8%(4/106)) were higher in the early onset infection group compared with the late onset group(P all<0.05). However, the number of cases who had fever(25.4%(18/71)vs.85.8%(91/106)) and complicated with purulent meningitis (29.6%(21/71) vs. 53.8%(57/106)) in early onset infections group was less than that in the late onset group(P both<0.05). The blood cultures of most patients (87.8%) were performed before the use of antibiotics. Drug-resistant tests showed that the sensitive rates to penicillin G, ceftriaxone and cefotaxime were 98.9%, 99.0% and 99.0% respectively. All strains were sensitive to vancomucine. The rates of resistance to clindamycin and erythromycin were 68.0% and 34.0%, respectively. Only 39 cases (22.0%) were treated with single antibiotics of either penicillins or cephalosporins, 80 cases (45.2%) were treated with antibiotics containing β lactamase inhibitor, 61 cases (34.5%) were treated with either meropenem or cefoperazone-sulbactam. One hundred and fifty-four cases were cured, while 19 died (including 13 complicated with purulent meningitis) and 8 lost to follow up after giving up of treatment. CONCLUSION The incidence and mortality of blood stream infection caused by Streptococcus agalactiae complicated with purulent meningitis are high in children. Penicillin is the first choice in treatment. Antibiotics should be selected accorrding to the drug-resistance test.

Abstract
PURPOSE To investigate the expression and role of human Dachshund homolog1(DACH1)in the development and prognosis of tongue squamous cell carcinoma(TSCC). METHODS The expression of DACH1 was detected immunohistochemistrically in 51 samples of paraffin-embedded TSCC, paired adjacent tissues and 25 samples of atypical hyperplasia tissues of the tongue. Statistical analysis was performed using SPSS 16.0 software package. RESULTS The results showed that 36 out of 51 TSCCs (70.6%) expressed lower levels of DACH1 compared with the paired adjacent tissues. Moreover, there was significant differences in expression of DACH1 between TSCC and paired adjacent tissues (P<0.05), and lower expression was associated with poor differentiation of tumors, advanced clinical stage and lymph node metastasis(P<0.05).In addition, the expression level of DACH1 in atypical hyperplasia tissues of tongue was also significantly lower than in tumors(P<0.05). Univariate survival analysis showed that the overall survival rate of patients with high expression of DACH1 was significantly higher than those with low expression of DACH1 (P<0.05). CONCLUSIONS The decreased expression of DACH1 may be related to occurrence, development and poor prognosis of TSCC. It may contribute to making diagnosis for precancerous lesions in the tongue, and provide a potential effective therapeutic target for TSCC.

Abstract
Haemonchus contortus is one of the most significant strongylid nematodes infecting small ruminants, and it causes great economic losses to the livestock industry worldwide. Accurate diagnosis of H. contortus is crucial to control strategies. Traditional microscopic examinations are the most common methods for the diagnosis of H. contortus , but they are time-consuming and inaccurate. Molecular methods based on PCR are more accurate, but need expensive machines usually only used in the laboratory. Loop-mediated isothermal amplification (LAMP) is a rapid, simple, specific, and sensitive method that has been widely used to detect viruses, bacteria, and parasites. In the present study, a LAMP method targeting ribosomal ITS-2 gene for detection of the H. contortus in goat fecal samples has been established. The established LAMP method was H. contortus specific, and the sensitivity of LAMP was the same as that of the H. contortus species-specific PCR, with the lowest DNA level detected as being 1 pg. Examination of the clinical samples indicated that the positive rate of LAMP was higher than that of PCR, but no statistical difference was observed between LAMP and PCR (χ2 = 17.991, P = 0.053). In conclusion, a LAMP assay with a high specificity and a good sensitivity has been developed to detect H. contortus infection in goats. The established LAMP assay is useful for clinical diagnosis of H. contortus .

Abstract
OBJECTIVE To investigate the expression and role of human Dachshund homolog 1 (DACH1) in the tongue squamous cell carcinoma (TSCC). STUDY DESIGN To explore the expression, regulation, and mechanism of DACH1 in TSCC, nine samples of fresh tumor and adjacent tissues, 51 samples of paraffin-embedded TSCC and paired adjacent tissues, and TSCC cell line SCC-25 were examined. Immunohistochemistry, real-time polymerase chain reaction, Western blot, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, colony formation, Transwell, adhesion assays, and flow cytometry were used. RESULTS The DACH1 expression level was significantly lower in tumors than in the adjacent tissues, and such low expression was associated with poor differentiation of tumors, late clinical stage, and lymph node metastasis. Moreover, overexpression of DACH1 might promote apoptosis and inhibit the proliferation, migration, and adhesion of SCC-25 cells. CONCLUSIONS DACH1 may be a potential molecular target for the therapy of recurrent and metastatic TSCC.

Abstract
BACKGROUND Treatments for autoimmune blistering diseases have significant risk of medical complications and quality of life impacts during treatment, and it is difficult to differentiate these impacts from disease burden or the effects of treatment. OBJECTIVES To develop a quality of life instrument specific to the effects of treatments used in patients with autoimmune bullous disease (AIBD). METHODS A comprehensive item generation process was used to build a 45-item pilot Autoimmune Bullous Disease Quality of Life (ABQOL) questionnaire, distributed to 70 patients with AIBD. Experts in bullous disease refined the pilot ABQOL, selecting only those questions pertaining to the treatment effects. This pilot Treatment of Autoimmune Bullous Disease Quality of Life (TABQOL) questionnaire was administered to 70 patients, before factor analysis was performed to yield the final questionnaire of 17 questions. Validity and reliability were evaluated across a range of indices. RESULTS Face and content validity were established through a comprehensive patient interview process, expert review and summaries of treatments used. The questionnaire was found to have appropriate correlation with the Dermatology Life Quality Index (r = 0.64) and the level of treatments used (P < 0.01), and was found to be responsive to overall variations in treatment burden. The TABQOL was also found to be a reliable instrument as evaluated by internal consistency (Cronbach α = 0.892) and test-retest reliability (r = 0.99). CONCLUSIONS We have shown that the TABQOL questionnaire is a valid and reliable instrument that may to be used to measure treatment burden in AIBD and serve as an end point in clinical trials.

Abstract
A broad range of human leukemias carries RUNX1 and MLL genetic alterations. Despite such widespread involvements, the relationship between RUNX1 and MLL has never been appreciated. Recently, we showed that RUNX1 physically and functionally interacts with MLL, thereby regulating the epigenetic status of critical cis-regulatory elements for hematopoietic genes. This newly unveiled interaction between the two most prevalent leukemia genes has solved a long-standing conundrum: leukemia-associated RUNX1 N-terminal point mutants that exhibit no obvious functional abnormalities in classical assays for the assessment of transcriptional activities. These mutants turned out to be defective in MLL interaction and subsequent epigenetic modifications that can be examined by the histone-modification status of cis-regulatory elements in the target genes. RUNX1/MLL binding confirms the importance of RUNX1 function as an epigenetic regulator. Recent studies employing next-generation sequencing on human hematological malignancies identified a plethora of mutations in epigenetic regulator genes. These new findings would enhance our understanding on the mechanistic basis for leukemia development and may provide a novel direction for therapeutic applications. This review summarizes the current knowledge about the epigenetic regulation of normal and malignant hematopoiesis by RUNX1 and MLL.

Abstract
Oral lichen planus is a chronic inflammatory disorder of the oral mucosa that represents T cell-mediated autoimmune diseases. The regulation and roles of carcinoembryonic antigen-related cellular adhesion molecule 1 (CEACAM1), a novel immune molecule, in the immunopathogenesis of T cell-mediated autoimmune diseases remain unclear. In the current paper, CEACAM1 was found to be overexpressed in peripheral T cells and epithelial cells in oral lichen planus patients. A fraction of infiltrating inflammatory mononuclear cells in the lamina propria of the oral lichen planus mucosa also expressed CEACAM1. Importantly, for the first time, CEACAM1 expression in T cells and in normal human oral keratinocytes was demonstrated to be regulated differently by osteopontin in vitro. Furthermore, the apoptosis of oral keratinocytes and activated T cells can be markedly suppressed by CEACAM1-specific monoclonal antibodies. In conclusion, OPN-regulated CEACAM1 expression may play a critical role in the immunopathogenesis of oral lichen planus.

Abstract
The aim of this study was to examine the Kif2a expression and its role in tumor progression, invasion and metastasis in squamous cell carcinoma of the oral tongue (SCCOT). The study included 44 cases of primary tumor and the corresponding adjacent tissues, 20 cases of primary tumor with lymph node metastasis. Immunohistochemistry was used to observe the Kif2a expression and its correlation with clinicopathologic factors in oral tongue cancer. The immunohistochemistry showed that Kif2a expression was stronger in oral tongue cancer tissues than in paired adjacent tissues (P<0.01), and the higher expression of Kif2a was also significantly associated with lymph node metastasis (P<0.01), tumor clinical stage (P<0.01). In addition, in vitro results from transwell chamber assay showed that Tca8113 cells transfected with Kif2a-siRNA had a decreased migratory ability (P<0.01) compared to nonsense-siRNA-transfected cells. Therefore we speculate the overexpression of Kif2a might be involved in the progression, invasion and metastasis of SCCOT and Kif2a should be as a predictor for prognosis.

Abstract
To investigate the expression of carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) and its effects on angiogenesis and lymphangiogenesis in oral carcinoma. Immunohistochemistry was used to study the expression of CEACAM1, LYVE1 and CD31, double-labelling immunofluorescence was used to detect the co-expression of CEACAM1 and LYVE1, and double-labelling immunohistochemistry was performed to observe the co-expression of LYVE1 and CD31 in vessels. Membranous CEACAM1 was expressed in well-differentiated squamous cell carcinoma and cytoplastic CEACAM1 in poorly and moderately differentiated carcinoma (P<0.05). More CEACAM1-positive vessels were observed in CEACAM1-positive tumors with cytoplasmic expression than with membranous expression (P<0.001). Co-expression of CEACAM1 and LYVE1, LYVE1 and CD31 in vessels was more common in CEACAM1-positive tumors with cytoplasmic expression than with membranous expression (P<0.001). CEACAM1 has different distribution in oral carcinoma. Membranous CEACAM1 inhibits angiogenesis and lymphangiogenesis, but cytoplasmic CEACAM1 promotes angiogenesis, and even promotes lymphangiogenesis by mediating the transformation of vascular endothelial cells (VECs) into lymphatic endothelial cells (LECs).

Abstract
Si-rich silicon oxide (SRO)/Er-Si-O/SRO multilayers were prepared on p-Si substrates using magnetron sputtering. X-ray diffraction measurements indicate that a mixture of silicates Er(2)Si(2)O(7) and Er(2)SiO(5) was formed after the multilayers were annealed at 1000 and 1150 °C. Strong Er(3+) 1.53 µm photoluminescence (PL) at room temperature has been observed from these multilayers and the full width at half-maximum of the 1.53 µm peak is less than 1.8 nm for the multilayers annealed at 1150 °C. Er(3+) 1.53 µm electroluminescence has been observed from erbium silicate films for the first time.

Abstract
BACKGROUND Analgesics are commonly used to provide pain relief after surgery. These drugs produce some extended depression of immunity. A prospective randomized controlled trial was designed to observe expressions of T-lymphocyte subsets (CD3(+), CD3(+)CD4(+) and CD3(+)CD8(+)), natural-killer cells (CD3(-)CD16(+)CD56(+)), and activated T-lymphocytes (CD3(+)CD25(+)) of patients undergoing gastric cancer surgeries and receiving patient-controlled intravenous analgesia (PCIA). METHODS Forty-five patients undergoing elective gastric cancer surgeries under general anesthesia were randomly allocated into 3 groups. Group I received PCIA using morphine after surgery, group II using tramadol, and group III using tramadol with lornoxicam. The analgesic efficacy was evaluated by visual analog scale (VAS) and Bruggrmann comfort scale (BCS). Expressions of CD3(+), CD3(+)CD4(+), CD3(+)CD8(+), CD3(-)CD16(+)CD56(+), and CD3(+)CD25(+) were measured as percentages of total lymphocytes by flow cytometer at 5 time points. RESULTS There was no significant difference in analgesic efficacy and the baselines of CD3(+), CD3(+)CD4(+), CD3(+)CD8(+), CD3(-)CD16(+)CD56(+), and CD3(+)CD25(+) in all groups. Compared with the baseline, CD3(+)CD8(+) had no changes in all groups at any time point. Ninety minutes after incision, CD3(+), CD3(+)CD4(+), CD3(-)CD16(+)CD56(+), and CD3(+)CD25(+) were lower in all groups (P<0.05). 24 h after surgery, CD3(+), CD3(+)CD4(+), CD3(-)CD16(+)CD56(+), and CD3(+)CD25(+) were lower in group I and group II (P<0.05); meanwhile CD3(+), CD3(+)CD4(+), and CD3(+)CD25(+) returned to the baseline but CD3(-)CD16(+)CD56(+) was still low (P<0.05) in group III. 48 h after surgery, CD3(+), CD3(+)CD4(+), CD3(-)CD16(+)CD56(+), and CD3(+)CD25(+) returned to the baseline in group II and group III, but not in group I (P<0.05). 72 h after surgery, CD3(+), CD3(+)CD4(+), CD3(+)CD4(+)/CD3(+)CD8(+) returned to the baseline, but CD3(+)CD25(+) and CD3(-)CD16(+)CD56(+) were still low in group I (P<0.05). CONCLUSION PCIA using lornoxicam with tramadol has the same good analgesic efficacy and less immunity depression than PCIA using morphine or tramadol.

Abstract
The aim of this work was the selection and comparison of representative infectious bursal disease virus (IBDV) strains. Nine strains of IBDV, isolated at different times and from different geographic regions of Europe and China, were characterized. Batches of all strains were prepared following standardized protocols and checked for the absence of contaminating viruses. Criteria used for their characterization were: (i) the nucleotide sequence of the VP2 variable region, (ii) binding to a panel of neutralizing monoclonal antibodies in antigen capture enzyme-linked immunosorbent assays, and (iii) virulence in specific pathogen free chickens after infection with a standardized number of median embryo infective doses. Based on the first two criteria, two of nine strains were classified as classical virulent (cv) IBDV (F52/70, Cu-1wt), and five as very virulent (vv) IBDV (849VB, 96108, HK46, GX, Harbin). Remarkably, although a clear-cut difference was demonstrable between European cvIBDV (F52/70 and Cu-1wt) and vvIBDV (849VB and 96108) strains, there was a continuum in the pathogenicity of Chinese vvIBDVs. Our results indicate the probable existence of differences in virulence within IBDV lineages determined on the basis of antigenic typing using monoclonal antibodies and the alignment of the VP2 sequences. This indicates limitations in the analysis of IBDV pathotypes based on the VP2 variable region and emphasizes that these criteria may not be sufficient for the classification of IBDV strains.

Abstract
We have consistently shown that several synthetic Organoselenium compounds are superior cancer chemopreventive agents and less toxic than selenite or certain naturally occurring selenoamino acids. 1,4-Phenylenebis(methylene)selenocyanate (p-XSC) is the lead Organoselenium compound in that it has been shown to be the most effective and the least toxic agent in several experimental cancer models. It is not known whether p-XSC or one of its metabolites is responsible for its chemopreventive efficacy. As an initial step, we synthesized one of its putative metabolites, i.e., the glutathione conjugate of p-XSC (p-XSe-SG), and determined its stability in the pH range from 2 to 8 and in the diet under normal feeding conditions. We also assessed its maximum tolerated dose and examined its chemopreventive efficacy against azoxymethane (AOM)-induced colon carcinogenesis in male F344 rats. p-XSe-SG proved to be very stable over the pH range tested. The maximum tolerated dose of p-XSe-SG determined in a 6-week subchronic toxicity study was found to be >210 ppm (>40 ppm selenium) when the compound was added to AIN-76A high-fat diet. To assess the efficacy of this agent in the postinitiation period of colon carcinogenesis, male F344 rats 6 weeks of age were fed the high-fat diet, and at beginning of weeks 7 and 8, all of the rats intended for carcinogen treatment were given AOM at a dose of 15 mg/kg body weight by s.c. injection. Two days after the carcinogen treatment, the groups of rats consuming the high-fat control diet began their respective high-fat experimental diet regimens with 0, 56, or 84 ppm p-XSe-SG (0.1, 10, and 15 ppm of selenium) supplementation. All animals continued on their respective diets for 38 weeks after the AOM-treatment and were then killed. Colon tumors were evaluated histologically using routine procedures and were also analyzed for cyclooxygenase (COX)-1 and COX-2 expression and enzymatic activities. The results indicate that p-XSeSG administered during the post-initiation stage significantly inhibited both the incidence (P < 0.05-0.01) and the multiplicity (P < 0.05-0.005) of AOM-induced colon adenocarcinomas. This agent also greatly suppressed the multiplicity (P < 0.01-0.001) of AOM-induced exophytic adenocarcinomas in a dose-dependent manner. Feeding of 56 or 84 ppm p-XSe-SG in the diet significantly suppressed total COX activity (P < 0.02 to -0.01) and COX-2 specific activity (P < 0.005-0.0005) but had minimal effect on the protein expression levels of COX-1 and COX-2. These results suggest that the newly developed synthetic Organoselenium compound, p-XSe-SG, is stable in the diet and at wide pH ranges, inhibits colon carcinogenesis when administered during the postinitiation stage, and inhibits COX activity. Compared with previous efficacy studies and considering the toxicity associated with selenium, p-XSe-SG seems to be the least toxic Organoselenium chemopreventive agent thus far tested in the experimental colon carcinogenesis. Studies are in progress to delineate whether p-XSe-SG is also effective when administered during the progression stage of colon carcinogenesis.

Abstract
Interleukin-10 (IL-10) has been shown to exert anti-inflammatory effects by suppressing macrophage proliferation and inhibiting cytokine production. In this study we show that in the presence of erythropoietin (EPO), the addition of IL-10 results in a significant dose-dependent increase in both Burst Forming Unit-Erythroid (BFU-E) and Colony Forming Unit-Erythroid (CFU-E) colony growth in both serum-containing and serum-free murine cultures in vitro. IL-10 acts at the later stages of erythroid cell proliferation and differentiation as the increase in colony number was greater in CFU-E than in BFU-E, and was similar when IL-10 was added to BFU-E cultures at the time of culture initiation as when its addition to culture was delayed for 7 days. Furthermore, no increase in BFU-E colony number was noted when IL-10, added at the time of culture initiation, was neutralized by the addition to culture of a monoclonal anti-IL-10 antibody up to 7 days later. The increases in BFU-E by IL-10 addition were not the result of prolongation of BFU-E colony lifespan, which was not significantly different in IL-10 treated and control cultures, respectively. Rather IL-10 stimulated the proliferation of erythroid clusters that were now large enough to be recognized as colonies. IL-10-induced stimulation of erythropoiesis appeared to be independent of its inhibitory effects on macrophage function, as stimulation of erythroid colony growth was similar in macrophage-containing and depleted cultures. Studies to determine if the IL-10 effect was direct or indirect yielded equivocal results. A limiting dilution assay suggested a direct effect. However, a log/log dose response curve with IL-10 did not pass through the origin suggesting an indirect effect. These studies indicate that IL-10 acts synergistically with EPO to significantly increase stimulation of erythroid differentiation and proliferation in vitro and may be involved in the regulation of normal erythropoiesis in vivo.

Abstract
The thermal stability of horse spleen apoferritin, a heteropolymer composed of 90% L and 10% H chains, has been studied by differential scanning calorimetry and compared with that of the human recombinant H homopolymer. The denaturation temperatures (Tm) are significantly higher for the horse spleen polymer than for the recombinant protein under all experimental conditions (e.g., at pH 7, Tm values are > or = 93 and 77 degrees C, respectively). The thermal denaturation process displays substantial reversibility for both polymers up to a few degrees below Tm, as indicated by CD measurements in the far and near uv regions. At temperatures higher than Tm the thermograms are influenced by the exothermic contribution of aggregation and/or precipitation. The H homopolymer thermogram, which is not distorted by the exotherm, is consistent with a multistate denaturation process. Acid dissociation of apoferritin produces stable dimeric subunits. The thermal unfolding of both dimeric subunits is reversible at least up to Tm and is characterized by an inversion of stability relative to the polymers (at pH 3.5, Tm is 42 degrees C for the horse spleen and 50 degrees C for the H subunit). These results indicate that the stabilization of the polymeric structure arises mainly from interactions between dimers, in accordance with the crystallographic evidence that the dimers are the building blocks of the polymeric molecule.

Abstract
Employing flow cytometry and a monoclonal antibody against the murine macrophage antigen, Mac-1, we found a significant increase in the number of marrow macrophages in aged mice. This was reflected as significant increase with age in the number of alpha-naphthyl acetate esterase positive cells, as well as in colony forming unit-macrophage (CFU-M) progenitor cells. Macrophages from the marrow of old mice generated significantly less tumor necrosis factor alpha (TNF alpha) than did macrophages from young mice, either spontaneously or when activated by granulocyte-macrophage colony stimulating factor (GM-CSF). Furthermore, conditioned medium (CM) derived from either marrow or peritoneal macrophages of old mice caused less suppression of burst forming unit-erythroid (BFU-E) colony growth than did CM obtained from young mice. Aging, therefore, is associated with an increase in the number of marrow macrophages that have an impaired ability to generate or release cytokines. The increase in macrophage number may reflect a compensation for their reduced function. Altered macrophage number and function may contribute to the age-related decline in hematopoietic reserve capacity.

Abstract
Interferon-gamma (INF-gamma) has been shown to suppress erythropoiesis and perhaps to contribute to the anemia of chronic disease. In this study we demonstrated that the concentration of INF gamma required to suppress murine burst forming unit-erythroid (BFU-E) growth was significantly less than that required to suppress colony forming unit-erythroid (CFU-E) growth. INF gamma acted at the most primitive step in erythroid progenitor cell differentiation and proliferation, as inhibition was maximal when added at the time of BFU-E culture initiation. Inhibition was progressively less if INF gamma addition was delayed after culture initiation. The effects of INF gamma on BFU-E did not require the presence of interleukin-1 alpha (IL-1 alpha), tumor necrosis factor-alpha (TNF alpha), or granulocyte macrophage colony stimulating factor (GM-CSF), as its effects were not neutralized by monoclonal antibodies against IL-1 alpha, TNF alpha, or GM-CSF. This applied whether INF gamma was added to culture with individual antibodies or with a combination of all three antibodies. INF gamma was not required for IL-1 alpha- or TNF alpha-induced suppression of BFU-E, as their effects were not neutralized by a monoclonal anti-INF gamma antibody. In contrast, GM-CSF-induced suppression of BFU-E was negated by the simultaneous addition of anti-INF gamma. We have previously shown that the addition of TNF alpha does not suppress BFU-E growth in cultures from marrow depleted of macrophages. Suppression did occur, however, if a small concentration of INF gamma that does not inhibit and increasing concentration of TNF alpha were added to culture, suggesting a synergistic effect between INF-gamma and TNF alpha. These observations suggest that INF gamma is a potent direct inhibitor of erythroid colony growth in vitro. It exerts its negative regulatory effect primarily on the earliest stages of erythroid progenitor cell differentiation and proliferation, as much higher doses are required to suppress late erythroid cell development. INF gamma is also involved in GM-CSF-induced inhibition of BFU-E colony growth.

Abstract
Increasing the rate of erythropoiesis in C57BL/6 mice, either by hypoxia or by the injection of recombinant erythropoietin (Epo), resulted in significant reductions in marrow macrophage number, as assessed by flow cytometry employing the monoclonal antibody against the macrophage antigen Mac-1 and by histologic determination of reductions in the number of marrow esterase-positive cells. This decline was paralleled by decreases in marrow colony-forming unit-macrophage (CFU-M) and colony-forming unit-granulocyte/macrophage (CFU-GM) number. The intramedullary concentration of the cytokines interleukin-1 alpha (IL-1 alpha) and tumor necrosis factor-alpha (TNF-alpha), which are produced by macrophages, was also reduced. Cessation of erythropoiesis was associated with increases in macrophage number, CFU-M and CFU-GM colony number, and IL-1 alpha concentrations. Increased erythropoiesis resulted in reductions in number of burst-forming unit-erythroid (BFU-E) colonies, which were less sensitive to suppression by macrophages as evidence by less increase in colony number when macrophages were removed from the marrow before in vitro BFU-E culture. BFU-E colony number was suppressed less when IL-1 alpha and TNF-alpha were added to cultures obtained from animals with stimulated erythropoiesis. Compared to controls, BFU-E number and suppression by macrophages increased significantly when erythropoiesis was reduced. These observations provide compelling evidence for a regulatory role for macrophages in normal erythropoiesis in vivo, presumably acting as a negative balance to the stimulatory effects of Epo.

Abstract
In recent years, it is known that endothelial cells play an important role in the genesis of some diseases, but there are only few papers dealing with the role of endothelial cells in leukemia. In this study some of the active factors released by the endothelial cells in patients with acute leukemia such as von Willebrand factor, prostaglandin, fibronectin, tissue-type plasminogen activator and its inhibitor were determined. It was found that the levels of these factors changed significantly in patients with acute leukemia, as compared with those in normal controls, especially in cases with bleeding tendency and infection. The possible mechanism and the clinical significance were discussed.

Abstract
It was observed that ohmefentanyl (OMF) and U-50488, when applied microiontophoretically, affected the spontaneous discharges of respiration related units (RRUs) in the nucleus of solitary tract of rat. Of the 44 RRUs recorded, OMF produced depressive effect in 21, excitatory in 7, biphasic effect in 5 while 11 units were not affected. Naloxone administered iontophoretically blocked both the depressive (6 out of 7) and the excitatory units (2 out of 3). Of the 45 RRUs recorded, U-50488 produced depressive effect in 15, excitatory in 5, biphasic effect in 3, while 22 units were not affected. Naloxone blocked both the U-50488 depression (7 out of 9) and excitation (1 out of 2) effect. U-50488 antagonized OMF-induced depression in 4 out of 6 units. The results suggest that depression and excitation produced by OMF and U-50488 may be mediated by different subtypes of opiate receptor.

Abstract
61 patients with cerebellar hemorrhage were studied. The age at onset ranged from 15 to 84 years with a mean of 57.4 years. 49 cases were treated conservatively and 12 surgically and the mortality rates of the two groups were 32.5% and 25% respectively. Based on this study, it is suggested that the clinical and CT indications of surgical treatment of hematoma are as follows; Severe disturbance of consciousness; Bilateral eyeball fixation; Volume of hematoma over 10 ml; Size of hematoma over 4 cm in diameter; Marked acute obstructive hydrocephalus; Compression of cisterna ambieus and quadrigeminus.

Abstract
Depletion of macrophages from murine marrow by the use of a monoclonal anti-macrophage antibody resulted in a significant increase in the number of erythroid burst forming units (BFU-E). This increase could be neutralized by the addition back to culture of macrophages or macrophage conditioned medium indicating that the suppression was mediated by soluble factors. To further characterize this effect, the addition to culture, either alone or in combination, of interleukin-1 alpha (IL-1 alpha), tumor necrosis factor alpha (TNF alpha), and granulocyte-macrophage colony-stimulating factor (GM-CSF) on the growth of BFU-E and the colony-forming unit granulocyte-macrophage (CFU-GM) was examined in macrophage-containing and macrophage-depleted cultures. The addition of IL-1 alpha to culture stimulated the release of both TNF alpha and GM-CSF and acted synergistically with both cytokines, resulting in a dose-dependent suppression of BFU-E and stimulation of CFU-GM growth. The increase in CFU-GM caused by the addition of IL-1 alpha was mediated by GM-CSF but not by TNF alpha as the increase was prevented by the addition of a monoclonal anti-GM-CSF antibody but not by anti-TNF alpha. When either TNF alpha or GM-CSF was neutralized by monoclonal antibodies the addition of IL-1 alpha resulted in a significant increase in BFU-E growth. The addition of GM-CSF to culture caused a dose-dependent suppression of BFU-E that was mediated by TNF alpha, as colony number was not reduced when GM-CSF and a monoclonal anti-TNF alpha antibody were simultaneously added to culture. TNF alpha-induced suppression of BFU-E only occurred in the presence of macrophages. In macrophage-depleted cultures, a dose-dependent suppression of BFU-E could be induced if subinhibitory concentrations of IL-1 alpha or GM-CSF were simultaneously added with increasing concentrations of TNF alpha. The effects of IL-1 alpha or GM-CSF and TNF alpha were markedly synergistic so that the doses required to induce suppression when added simultaneously was only 10% of that required when either were added to culture alone. Suppression of BFU-E by GM-CSF or the combined addition of GM-CSF and TNF alpha did not require IL-1 alpha because inhibition was not neutralized by the addition of anti-IL-1 alpha antibody.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
In the present study, the effects of microiontophoretically applied U-50488 on the spontaneous discharge of respitation related units (RRUs) in nucleus ambiguus or rats were observed. Of 96 RRUs recorded, U-50488 produced depressant effect on 51 units, excitative effect on 11 units, excitation followed by depression on 6 units, depression followed by excitation on 3 units. The remaining 25 units were not influenced. Naloxone administered iontophoretically not only blocked U-50488-induced depression in 12 out of 16 units, but also blocked U-50488-induced excitation in 2 units. Duration of the depression produced by U-50488 was remarkably longer than that of excitation. The result suggested that kappa receptor might be involved in respiratory regulation and that the subtype of opiate receptors which mediates depression and excitation effect might not be the same.

Abstract
In the present study, it was observed that ohmefentanyl (OMF) affected microiontophoretically applied spontaneous discharges of respiration related units (RRUs) in the nucleus ambigus of rats. Of 96 RRUS recorded, 48 units were depressed following OMF application, 14 units increased in discharges, 14 units increased and then decreased, 9 units decreased and then increased. The remaining 11 units were not influenced. Naloxone administered iontophoretically not only blocked OMF-induced depression in 11 out of 15 units, but blocked OMF-induced facilitation in 5 out of 6 units. U-50488 administered microiontophoretically antagonized OMF-induced depression in 9 out of 13 units. Duration of the depression produced by OMF was much longer than that of the facilitation. The result suggests that the subtype of opiate receptors mediating the depression seen to be different from that responsible for the facilitation.

Abstract
We determined whether the exposure of mouse epidermal cells to ultraviolet radiation (UVR) induces the production of factors that can stimulate the in vitro and in vivo growth of syngeneic melanoma cells. Epidermal sheets isolated from the back skin of C3H/HeN mice were placed into sterile medium and exposed to different doses of UVB radiation; 18 h later, culture supernatants were harvested. Supernatants of epidermal sheets not exposed to UVR served as controls. Supernatants from UVR-treated epidermal sheets, but not control supernatants, stimulated the in vitro and in vivo growth of some murine melanomas, but not cells of a fibrosarcoma, a hepatocellular carcinoma, or a squamous carcinoma. Supernatants of UVR-treated epidermal cells injected into the ears of syngeneic mice stimulated epidermal cell proliferation in a short-term assay. We conclude that UVR may contribute to the incidence of cutaneous melanoma by its ability to cause the release from epidermal cells of diffusible factors that promote the outgrowth of small numbers of melanoma cells.
