Abstract
The target gene sequences of the novel coronaviruses obtained by sequencing were compared with the reference sequences to analyze the genetic variation of the two cases of the novel coronaviruses from Inner Mongolia Autonomous Region in 2022 and to explore the sources of infection. The results showed that the two sequences belonged to different evolutionary branches, Delta (AY.122) and Omicron (BA.1.1), respectively. hCoV-19/Inner Mongolia/IVDC-591/2022 had 48 single nucleotide polymorphisms on the genome sequences, sharing 40 nucleotide mutation sites with a Mongolian strain; hCoV-19/Inner Mongolia/IVDC-592/2022 genome shared 57 nucleotide mutation sites with a UK strain, and the nucleotide mutation site identity was 100% (57/57). Phylogenetic analysis showed that the target gene sequences were not directly related to domestic novel coronavirus sequences during the same period, but were related to isolates from Europe and Mongolia.

Abstract
PURPOSE/OBJECTIVE(S) The clinical significance of radiographic progression during pre-operative radiation therapy (RT) for soft tissue sarcoma (STS) remains unclear. We sought to evaluate associations between radiographic change on T1 post-contrast (T1c) and T2 weighted magnetic resonance imaging (MRI) with percent pathological response (PR%), positive surgical margins (+SM), and local control (LC). MATERIALS/METHODS We retrospectively identified patients with STS undergoing neoadjuvant RT who had both pre- and post-RT MRI prior to surgical resection. Gross tumor volumes were contoured on pre- and post-RT T1c and T2 MRI sequences and relative change in volume from baseline was calculated. Radiographic classification was defined as response (>30% reduction), progression (>30% increase), or stable (≤30% reduction or ≤30% increase). Chi squared, Fishers Exact, and Kruskal Wallis (KW) tests were used to assess differences between groups. Linear and binary logistic regression models used to assess associations between MRI response and PR% and +SM, respectively. LC was modeled with Kaplan Meier methods and log rank tests. RESULTS A total of 68 STS patients were identified, with a median follow up of 49 months (range 7-229). With a median age of 60.5 years (25-88) and tumor size of 10.8cm (2.7-25.7), the most common histologies were undifferentiated pleomorphic sarcoma (UPS; 32.4%) and myxoid liposarcoma (ML; 16.2%), and were primarily grade 2-3 disease (89.7%). With a median RT dose of 50 Gy in 25 fractions (44-60Gy), the median radiographic volume change was 2% (-86.4 to 953.6%) and -2.1% (-89.6 to 962.5%) for T1c and T2, respectively. Radiographic classification of response/stable/progression was 25.4%/49.2%/25.4% and 27.9%/52.5%/19.7% for T1c and T2, respectively. Histology (ML vs. UPS) and grade (1 vs. 3) were predictors for radiographic response on both T1c (72.7% vs 18.8%, p = 0.03 and 71.4% vs. 10.4%, p = 0.03) and T2 (71.5% vs. 18.2%, p = 0.02 and 71.4% vs. 14.6%, p = 0.002), respectively. With 6 +SM (8.8%), the rate of +SM for response/stable/progression was 20%/10.3%/0% in T1c (p = 0.2) and 5.9%/12.5%/0% in T2 (p = 0.5). As a continuous variable, neither relative change on T1c (p = 0.2) or T2 (p = 0.4) were associated with +SM. With an overall median PR% of 64% (0-100%), the median PR% was significantly different for response/stable/progression for both T1c (95%/42%/73%, p = 0.02) and T2 (95%/50%/87.5%, p = 0.04). Radiographic change on neither T1c (p = 0.4) or T2 (p = 0.5) were associated with PR% on a continuous basis. With a total of 4 local recurrences, there was no significant difference in LC by radiographic classification on either T1c (p = 0.65) or T2 (p = 0.85). CONCLUSION While radiographic response may be correlated with pathological response, radiographic progression on either T1c or T2 following neoadjuvant RT was not associated with a detriment in surgical margins or local control. These findings suggest that STS radiographic "pseudoprogression" is not associated with worse outcome.

Abstract
PURPOSE/OBJECTIVE(S) Conventionally fractionated radiotherapy (CFRT) offers modest local control (LC) for unresected soft tissue sarcoma (STS). Although STS has a low α/β (∼2 - 6) that may benefit from a hypofractionated radiotherapy regimen, it is often limited due to the toxicity risk to surrounding organs. A simultaneous integrated boost to gross disease (2.5 - 3 Gy/fraction), with lower doses to the intermediate and low risk target volume, may offer a safe isotoxic dose escalation approach. We hypothesize that this hypofractionated accelerated radiotherapy dose-painting (HARD) will improve local control compared to CFRT. MATERIALS/METHODS We performed a single institution retrospective analysis of patients who received external beam radiotherapy with definitive intent (≥50 Gy) for unresected STS. CFRT was defined as 1.8 - 2 Gy/fraction (Gy/fx). HARD regimens consisted of 60 - 66 Gy at 3 Gy/fx or 70 Gy at 2.5 Gy/fx to gross disease, with 1.8 - 2.4 Gy/fx to intermediate and low risk regions. All anatomical sites and histologies were included. Local control (LC) was defined from date of current diagnosis, estimated by Kaplan-Meier methods via log-rank tests or Cox regression for univariate analysis (UVA), when appropriate. Cox regression multivariate analysis (MVA) included regimen, biological effective dose (α/β 6; BED6), lesion size, age, and grade. RESULTS We identified 77 patients with primary and metastatic STS treated with HARD (n = 40) or CFRT (n = 37) between 1990 and 2022, with a median follow up of 24 months in surviving patients. The mean dose for CFRT and HARD are 56.8 Gy (50 - 77.4 Gy) and 64.9 Gy (60 - 70 Gy), respectively. HARD was comprised of 65% for 3 Gy/fx and 35% for 2.5 Gy/fx regimens. At the time of RT, grade 3 (69%) and extremity (39%) tumors were the most common. Tumor histology was very heterogenous across both cohorts, with undifferentiated pleomorphic sarcoma being the most common for HARD (33%) and CFRT (19%). HARD was more often utilized in stage IV patients (55% vs. 19%, p = 0.001) and had a higher mean BED6 (96 vs. 74.2 Gy, p < 0.001) than CFRT, but without differences in age (67 vs. 59 years), tumor size (8 vs. 10 cm), concurrent chemotherapy (35% vs. 30%), Karnofsky performance status (86 vs. 85), follow-up (19 vs. 28 months), and grade (all p > 0.1). On UVA, there was a LC benefit associated with higher BED6 (HR 0.94, 95% CI 0.9 - 0.98, p = 0.002) and the HARD regimen (2-year LC 95% vs. 62%, p < 0.001). On MVA, only HARD (HR 0.07, 95% CI 0.006 - 0.729, p = 0.027) was independently associated with LC. CONCLUSION Although the HARD regimen and higher BED6 were both associated with significant improvement in LC, only the HARD regimen independently associated with a local control benefit for unresected STS. These results suggest biologic dose-intensification exploiting the low α/β of STS with an isotoxic hypofractionated regimen may be a favorable strategy for unresectable STS. Future prospective studies are necessary to validate these findings.

Abstract
PURPOSE/OBJECTIVE(S) In current clinical practice for fractionated radiotherapy (RT) patients receive a fixed fractionation protocol throughout radiation course. Radiation oncology has not yet moved toward adaptive fractionation to change RT fractionation based on individual patients' response dynamics. We have previously introduced a novel mathematical and imaging biomarker, proliferation saturation index (PSI), to simulate and evaluate tumor volume dynamics during therapy. Robust tumor volume reduction was associated with lower PSI, and PSI has been utilized to select fractionation schedules for the first mathematical model informed clinical trial. Here we simulate the possibility of adapting the selection of RT fractionation on a week-by-week basis by utilizing a dynamic weekly estimation of PSI. MATERIALS/METHODS We generated a cohort of in silico patients by sampling from distributions of PSI, radiosensitivity, and growth rate parameters. These distributions were by pre-treatment and on-treatment tumor volume dynamics from a prospective clinical trial (NCT03656133), where 49 HPV+ OPC patients were treated with either 2 Gy daily fractions up to a total of 70 Gy if PS<0.75, or hyperfractionation at 1.2 Gy b.i.d. up to a total of 66 Gy for patients with PSI ≥ 0.75. We then simulated standard (2 Gy q.d.) and hyperfractionated (1.2 Gy b.i.d) for 1-8 weeks of RT to build a library of response dynamics for the different parameter combinations and treatment durations. This library was then used to estimate optimal adaptive fractionation schedules for the in silico patients that maximized tumor volume reduction and minimized total RT dose. RESULTS We found that PSI evolved towards lower values (i.e., higher proliferative fractions) over the fractionation RT treatment course. For patients that began treatment with standard fractionation, no adaption was found to be superior to uniform fractionation. For selected patients who began treatment with hyperfractionation, however, the optimal fractionation schedule included a period of upfront hyperfractionated RT followed by a switch to standard fractionation at different times during their treatment course. CONCLUSION The results of this study suggest that in addition to selecting the best initial fractionation schedule, a novel approach to personalize RT for OPC patients may include adapting the fractionation based on early treatment response dynamics. These results motivate validation in prospective clinical trials.

Abstract
AIM To investigate the diagnostic value of quantitative susceptibility mapping (QSM) in mild cognitive impairment (MCI) of aluminium (Al) workers. MATERIALS AND METHODS The basic data of 53 workers in an Al factory were collected and divided into the MCI group and normal control (NC) group by Montreal Cognitive Assessment (MoCA) scores. All participants were tested for plasma Al concentration and had magnetic resonance imaging (MRI). The QSM values of many areas of the brain were delineated and measured. Independent two-sample t-tests or non-parametric tests were used to compare the parameter values between the two groups. Spearman's correlation analysis was performed between QSM values, MoCA scores, and plasma Al concentration. The receiver operating characteristic curve and z test were performed to assess diagnostic efficacy and the best parameter. RESULTS There was no difference in age and educational level. Plasma Al concentration of the MCI group was higher than that of NC group (p=0.057). QSM values of the left hippocampus, left dentate nucleus, right substantia nigra, and left putamen in MCI group were higher than that of NC group (p<0.05), and the left hippocampus had the best diagnostic efficacy. QSM values correlated negatively with MoCA scores. No correlation was found between QSM values and plasma Al concentration (p>0.05). CONCLUSION QSM might be a neuroimaging marker for the diagnosis of MCI. The left hippocampus showed the best diagnostic efficacy. Plasma Al concentration of the MCI group was higher than that of the NC group. A correlation between QSM and plasma Al concentration was not found.

Abstract
Metabolism in most organisms can show variations between the day and night. These variations may also affect the composition of products derived from livestock. The aim of the present study was to investigate the difference in composition between the day milk and night milk of dairy cows. Ten multiparous Holstein cows (milk yield = 25.2 ± 5.00 kg/d) were randomly selected during mid lactation. Milk samples were collected at 0500 h ("night milk") and 1500 h ("day milk") and analyzed to determine their composition. Mid-infrared spectroscopy was used to analyze macronutrient content of milk. Metabolomics and lipidomics were used to detect and analyze small molecules and fatty acids, respectively. An automatic biochemical analyzer and ELISA kits were used to determine biochemical indicators, as well as antioxidant and immune parameters in the milk. Though milk fat, protein, lactose, and total milk solids were not different between day milk and night milk, small molecules, metabolites and lipids, and hormones and cytokines differed between day milk and night milk. Regarding biochemical and immune-related indicators, the concentrations of malondialdehyde, HSP70, and HSP90 in night milk were lower than that in day milk. However, interferon-γ levels were higher in night milk. Additionally, night milk was naturally rich in melatonin. Lipidomics analyses showed that the levels of some lipids in night milk were higher than those in day milk. Metabolomics analyses identified 36 different metabolites between day milk and night milk. Higher concentrations of N-acetyl-d-glucosamine, cis-aconitate, and d-sorbitol were observed in day milk. However, the other 33 metabolites analyzed, including carbohydrates, lipids, AA, and aromatic compounds, showed lower concentrations in day milk than in night milk. The present findings show that the composition of night milk differs considerably from that of day milk. Notable changes in the circadian rhythm also altered milk composition. These results provide evidence to support the strategic use and classification of day milk and night milk.

Abstract
Abatement of odour emissions in poultry production is important to ensure the quality and safety in the poultry industry as well as for the benefit of the environment. This study was conducted to compare the effects of supplementation with different amounts of dietary soybean oligosaccharides (SBO) and chlortetracycline (CHL) on the major odour-causing compounds in the excreta and on the caecal microbiota in broiler chickens. One-day-old broiler chickens were subjected to a 42-day experiment involving 6 treatments with 6 replicates per treatment (10 birds/cage). The treatments were as follows: negative control (NC; basal diet), positive control (PC; basal diet supplemented with CHL) and basal diet supplemented with 0.5, 2.0, 3.5 and 5.0 g/kg SBO (0.5SBO, 2.0SBO, 3.5SBO and 5.0SBO, respectively). Fresh excreta were sampled for the analysis of odour compounds by HPLC. Caecum content was collected for the caecal microbiota analysis through 16S rRNA sequencing. Results showed that on day 42, the excreta indole concentration in the broilers fed with 2.0SBO, 3.5SBO and 5.0SBO and PC was significantly decreased (P < 0.01) compared with that in the NC-fed broilers. The excreta skatole concentration (P < 0.001) and pH (P < 0.05) were also decreased by SBO and CHL, and they were lowest in birds fed with 3.5SBO. The formate concentrations in birds fed with 3.5SBO and 5.0SBO were higher than those in birds fed with the other diets (P < 0.001). Similarly, acetate concentration (P = 0.003) was increased in birds fed with 3.5SBO. Deep sequencing of 16S rRNA revealed that the composition of the caecal microbial digesta was slightly or significantly changed by the SBO or by the CHL supplementation, respectively. The SBO supplementation decreased the abundance of Bacteroides, Bilophilaand Escherichia, which were associated with the skatole and indole concentrations in the excreta. By contrast, the CHL supplementation demonstrated a strong tendency to enrich Ruminococcus and to reduce the abundance of Rikenella. These results indicated that supplementation with dietary SBO is beneficial in attenuating the concentration of odour-causing compounds and that it modulates the composition of caecal microbiota in broiler chickens.

Abstract
Objective: To analyze clinical features, diagnosis, treatment and prognosis of pregnancy-related lymphocytic hypophysitis (LyH). Methods: The clinical data of 16 cases diagnosed as pregnancy-related LyH at Chinese PLA General Hospital between October 2010 and November 2019 were reviewed. Results: Sixteen patients were included (aged 20-40 years). All patients' symptoms occurred from the last 2 months of pregnancy to 12 months postpartum, with 6 cases in the third trimester and 10 cases during postpartum, and all the patients were diagnosed after delivery. Six patients had lymphocytic adenohypophysitis (LAH), 4 patients had lymphocytic infundibuloneurohypophysitis (LINH), 4 patients had lymphocytic panhypophysitis (LPH), and 2 had lymphocytic hypothalamitis. Eight patients presented with symptoms of intracranial space-occupying lesions, 14 patients had symptoms of anteriorpituitary hormone deficiencies, 9 patients had central diabetes insipidus (CDI), and 2 had hyperprolactinemia. Pituitary MRI showed that the pituitary presented with diffuse enlargement, pituitary stalk thickening, disappearing of high-intensity signals in posterior pituitary and space-occupying lesions in the infundibulum of hypothalamus. Nine patients were treated with immunosuppressive agent, 3 patients alleviated the space-occupying effects after surgery, and 4 patients recovered spontaneously. Fourteen patients were followed up with a period of 3-98 months. Four patients had a relapse, 2 patients had a complete remission, and 12 patients needed long-term hormone replacement therapy. Conclusions: Clinical manifestations of pregnancy-related LyH are diverse. LyH should be suspected in pregnant or postpartum women with a sellar mass to avoid missed diagnosis or misdiagnosis. Immunosuppressant therapy is effective. Overall, LyH patients have a favorable prognosis.

Abstract
OBJECTIVE Human blood plasma is a complex that communicates with most parts of the body and reflects the changes in the state of an organism. Identifying age-related biomarkers can help predict and monitor age-related physiological decline and diseases and identify new treatments for diseases. METHODS AND PARTICIPANTS In this study, TMT-LC-MS/MS was utilized to screen differentially expressed plasma proteins in 118 healthy adults of different ages. Participants were divided into three groups: 21-30 years of age (Young), 41-50 years of age (Middle) and ≥60 years of age (Old). RESULTS The number of differentially expressed proteins in the comparisons of Young vs Middle, Middle vs Old and Young vs Old were 82, 22 and 99, respectively. These proteins were involved in numerous physiological processes, such as "negative regulation of smooth muscle cell proliferation" and "blood coagulation". Moreover, when Young was compared with Middle or Old, "complement and coagulation cascades" was the top enriched pathway by KEGG pathway enrichment analysis. Functional phenotyping of the proteome demonstrated that the plasma proteomic profiles of young adults were strikingly dissimilar to those of the middle-aged or older adults. CONCLUSIONS The results of this study mapped the variation in the expression of plasma proteins and provided information about possible biomarkers/treatments for different age-related functional disorders.

Abstract
The standard of care trimodality therapy for resectable locally advanced esophageal adenocarcinoma is complex and necessitates multidisciplinary care and expertise. In this work, it is hypothesized that facility clinical volume and utilization of intensity-modulated radiotherapy (IMRT) may influence outcomes. The National Cancer Data Base was queried for patients with cT1-4-N0-3 M0 esophageal adenocarcinoma undergoing trimodality therapy from 2004 to 2013 (n = 2445). All patients received chemoradiation followed by esophagectomy at a Commission on Cancer facility. The facility volume was categorized into tertiles: high-volume centers (HVCs) in the highest 25th percentile of cases per year, intermediate-volume centers (IVCs) with the next highest 25th percentile of cases, and low- and very low-volume centers (LVCs) in the lowest 50th percentile. Overall survival (OS) was estimated using Kaplan-Meier methods and Cox proportional hazard regression. Propensity score matching to balance patient characteristics between volume centers was performed. Subgroup analysis was done comparing IMRT versus 3D conformal radiotherapy. The median follow-up was 26 months. Treatment at an HVC (hazard ratio 0.63, 95% CI 0.49-0.81, P < 0.001) was found to be independently associated with improved overall survival in multivariable analysis. Three-year OS was 58.4%, 46.2%, and 47.5% for HVCs, IVCs, and LVCs, respectively (P < 0.001). Patients at HVCs were more likely to receive IMRT over 3D chemoradiation (CRT; OR 3.45, 95% CI 2.4-5.0, P < 0.001). Patients treated using IMRT at HVCs had improved OS compared to those treated at IVCs or LVCs (HR 0.68, 95% CI 0.52-0.90, P < 0.01), while patients treated with 3D CRT at HVCs had no survival advantage over those at IVCs or LVCs (P = 0.28). Patients with locally advanced esophageal adenocarcinoma treated with IMRT and at HVCs appear to have improved survival.

Abstract
The experiment was conducted to investigate the in vitro effects of inulin and soya bean oligosaccharide (SBO) on the metabolism of L-tryptophan (L-try) to skatole production, and the intestinal microbiota in broilers. Treatments were as follows: caecal microbiota control (Cc), Cc + inulin, Cc + SBO, rectal microbiota control (Rc), Rc + inulin and Rc + SBO. Microbial suspensions were anaerobically incubated at 38°C for 24 hr. The results showed that concentrations of skatole and acetic acid were significantly lower in caecal microbiota fermentation broth (MFB) than those in rectal MFB (p < .05). Addition of inulin or SBO significantly decreased the concentrations of indole and skatole and rate of L-try degradation (p < .05). Inulin groups had lower indole than SBO groups (p < .05). PCR-DGGE analysis revealed that addition of inulin or SBO decreased the microbiota richness (p < .05), but no significant differences in Shannon index (p > .05). Four distinct bands were detected in inulin and SBO groups, which were related to two of Bacteroides, one of Firmicutes and Bifidobacteria. Six bands were detected only in control groups, which represented uncultured Rikenellaceae, Roseburia, Escherichia/Shigella dysenteriae, Bacteroides uniformis (T), Parabacteroides distasonis and Enterobacter aerogenes. Populations of Lactobacilli, Bifidobacteria and total bacteria in inulin groups were higher than those in control groups (p < .05). For SBO groups, only population of total bacteria increased (p < .05). However, there were no significant differences in Escherichia coli population among treatments (p > .05). These results suggest that reduced concentrations of skatole and indole in the presence of inulin and SBO may be caused by decrease in L-try degradation rate, which were caused by change in microbial ecosystem and pH value. Uncultured B. uniformis (T) and E. aerogenes may be responsible for degradation of L-try to skatole.

Abstract
Objective: To analyze clinical features, prognosis and treatment of lymphocytic hypophysitis (LYH). Methods: The clinical data, treatments and outcomes of 18 cases diagnosed as LYH at Chinese PLA General Hospital between January 2001 and July 2017 was respectively reviewed. Results: Eighteen patients with histology-proven LYH (13 females and 5 males ) were identified. All lymphocytic adenohypophysitis (LAH) were females(n=6), two of whom were associated with pregnancy. Eleven patients (6 females and 5 males) had lymphocytic panhypophysitis (LPH) and one(female) had hypothalamitis. Pre-treatment evaluation revealed that 11 patients presented with symptoms of intracranial space-occupying lesions, 12 patients had symptoms of anterior pituitary hormone deficiencies, and 12 patients had central diabetes insipidus (CDI). All patients had space-occupying lesions on magnetic resonance imaging (MRI), which were symmetrically enlarged and homogenously enhanced with or without pituitary stalk thickening. Before or after surgery, 11 patients received immunosuppressant therapy or radiotherapy to alleviate space-occupying effect. After 4-204 months follow-up, 5 patients had a relapse and received immunosuppressants, radiotherapy or surgery to achieve remission. Full recovery (both symptomatic and radiographic) was seen in 6 patients, and 11 patients maintained stable replacement therapy. Conclusions: LYH presents with acute space-occupying effects such as headache, visual disturbances, hypopituitarism, CDI and mild hyperprolactinemia, especially with characteristic radiographic manifestations. Usually, surgery reliably establishes diagnosis, and immunosuppressant therapy is a necessity. On the whole, LYH has a good prognosis.

Abstract
Objective: To evaluate the efficacy of 24 h urinary free cortisol (24 h UFC) in the diagnosis of subclinical Cushing's syndrome (SCS), and explore the best diagnostic cut-off value. Methods: The clinical data of patients with adrenal incidentaloma in Chinese PLA General Hospital between January 2008 and December 2016 was retrospectively reviewed and analyzed. All SCS patients were diagnosed based on the current Cushing's syndrome (CS) guidelines and confirmed by histopathology and then treated as study group, and additional patients with non-functional adrenal adenoma (NFA) were enrolled as control group. ROC curve was used to evaluate efficacy of 24 h UFC and 24 h UFC to creatinine ratio (UFCCR), and explore their best cut-off values. Results: There were 161 patients with NFA, of which contained 84 males and 77 females, with a mean age of (51.02±10.49) years old. There were 88 patients with SCS, of which contained 26 males and 62 females, with a mean age of (51.74±10.29) years old. The 24 h UFC and UFCCR levels were significant higher in SCS group than those in NFA group[510 (363, 698) nmol vs 335 (209, 467) nmol for 24 h UFC, and 7.82(4.79, 12.13) ml vs 4.82(2.41, 6.57)ml for UFCCR, both P<0.05]. ROC analysis showed that the optimal cut-off for 24 h UFC was 480 nmol (AUC 0.716, 95% CI: 0.648-0.784, with a sensitivity of 58.0% and a specificity of 79.4%) and the optimal cut-off for UFCCR was 6.84 ml (AUC 0.729, 95% CI: 0.662-0.796, with a sensitivity of 59.1% and a specificity of 78.7%). Conclusions: The recommended cut-off points of 24 h UFC and UFCCR for diagnosing SCS in AI patients were 480 nmol and 6.84 ml, respectively.

Abstract
Objective: To summarize and analyze the clinical features and etiologies in hospitalized patients with syndrome of inappropriate antidiuretics (SIAD) during the past 25 years. Methods: All data of 128 patients with SIAD admitted to Chinese PLA General Hospital since January 1991 to January 2016 were collected. SIAD was diagnosed based on the 1957 criterion. Results: (1) The most frequent causes of increased inappropriate secretion of vasopressin were malignant tumors, lung diseases (e. g. pneumonia), and central nervous system diseases, in which malignant tumors accounted for 38.28% of the SIAD. (2) During the past 25 years, the proportion of malignant diseases declined from 4/7 to 35.29%, while, the proportion of pulmonary infection increased from 1/7 to 35.29% (P<0.05). (3) The patients with malignant tumors had the lowest serum sodium and serum osmolality among all SIAD patients. (4) CT scan had a high diagnostic value for chest and brain detection. (5) Among three SIAD subjects with unknown reasons at onset, two were diagnosed with small cell lung cancer and one with gastric cancer during follow-up. Conclusion: The etiology of SIAD is complex and it could be attributed to multifarious etiological factors. Malignant tumors account for the largest proportion of all patients, and pulmonary infection was ranked in second place. Cautions on tumors have to be taken when serum sodium of a SIAD patient is below 118.1 mmol/L.

Abstract
Objective: To determine the effect of the surgical and conservative approaches on the metabolic profiles in patients with subclinical Cushing's syndrome (SCS) in adrenal incidentalomas (AI). Methods: A hundred and thirty AI patients with SCS in Department of Endocrinology, PLA General Hospital between January 2008 and December 2016 were studied, surgery was performed in 88 patients (surgical group), and the rest received conservative approach (conservative group). The improvement/worsening of blood pressure, blood glucose, lipid profiles and body weight after a duration of >18 months follow-up were analyzed, respectively. Results: Baseline demographics, clinical characteristics were similar between surgical and conservative groups. In the surgical group, blood pressure, blood glucose, lipid profiles and body weight improved more frequently than that in conservative group (29.69% vs 3.12%, P=0.003; 10.94% vs 3.12%, P=0.262; 7.81% vs 3.12%, P=0.660; 39.06% vs 9.38%, P=0.004, respectively). In conservative group, blood pressure, blood glucose, lipid profiles and body weight worsened more frequently than that in surgical group (28.13% vs 0, P<0.001; 25.0% vs 0, P<0.001; 18.75% vs 0, P=0.003; 40.62% vs 20.31%, P=0.051, respectively). Logistic regression analysis indicated surgical treatment was associated with improvement of blood pressure (OR=10.687, 95%CI: 1.279-89.299) and weight loss (OR=5.541, 95%CI: 1.404-21.872) independently of gender, age, duration of follow-up, serum cortisol level after 1 mg-dexamethasone suppression test and the mass size. Conclusion: In AI patients with SCS, surgery was beneficial in the aspect of metabolic profiles.

Abstract
To improve the differential diagnosis of sellar region mass, 4 cases with sellar mass and misdiagnosed as lymphocytic hypophysitis (LYH) were reviewed retrospectively.The 4 patients (2 male and 2 female) aged 20-60 years old were all presented with symptoms of headache, polydipsia and polyuria.Biochemical studies confirmed the diagnoses of central diabetes insipidus and hypopituitarism.Head MRI scans showed LYH like image for all the cases, and, thus, high dose methylprednisolone pulse therapy (HDMPT) was applied to the patients.Their symptoms deteriorated and the sellar mass enlarged after a short period of partial improvement.Operations were performed in all the patients.Histology study showed craniopharyngioma with abscess, primary abscess, secondary hypophysitis caused by Wegener's granulomatosis, and germinoma with secondary hypophysitis, respectively.In conclusion, surgery or biopsy is necessary for those who presented with sellar region mass and was suspected to be with LYH, but with poor response or even worse after HDMPT.

Abstract
OBJECTIVE To summarize ultrasound features associated with medullary thyroid carcinoma (MTC) and investigate the predictive value of ultrasonography in preoperative diagnosis of MTC. METHODS The sonographic and clinical data were studied in a series of nodules histologically proven as MTC collected from January 1993 to January 2013. RESULTS A total of 86 patients (92 nodules proven as MTC) were enrolled in the study with an average age of (47±12) years.Among the MTCs, 21.7%(20/92) were excluded because of missing data and the remained 78.3%(72/92) had complete data with the average diameter of (2.1±1.3) cm.The common US findings for MTC were solid, hypoechogenicity, regular sharp, well-defined margin, AP/ TR<1 and calcification (mostly microcalcification). Calcification and vascularization were more common in MTC nodules(48.6% vs 5.6%, P=0.001). Nodules with enlargement of cervical lymph node tended to be undergone FNAB(76.0% vs 55.3%, P=0.084), and ill-defined margin was more common in MTC nodules with cervical lymph node metastasis(36.4% vs 12.8%, P=0.009). CONCLUSION Despite having a few US features closely linked to the malignant nodules such as solid, hypoechogenicity and with microcalcification, the MTC nodules also have specific US imaging characteristics as regular sharp, well-defined margin and AP/ TR<1.

Abstract
Objective: To analyze the clinical features and outcomes of congenital adrenal hyperplasia (CAH) with adenomatoid adrenal gland. Methods: Nineteen patients clinically confirmed as CAH with adenomatoid adrenal gland, from 2008 to 2015 in Deparment of Endocrinology of Chinese PLA General Hospital, were retrospectively analyzed, and the outcomes of the treatment were followed up. Results: Seventy-six patients were clinically confirmed as CAH, from 2008 to 2015 in PLA hospital. Nineteen of them have accompanied with adenomatoid adrenal gland. Of the 19 confirmed cases, 7 were male, and 12 were female. The mean age was (33.3±14.8) years old. Nineteen confirmed cases were consisted of 10 cases of 21-hydroxylase deficiency (OHD), 6 cases of 17α-OHD, and 3 cases of 11β-OHD. Of the 19 cases, 5 cases presented with adrenal hyperplasia with left side adenomatoid solid lesion, 2 cases presented with adrenal hyperplasia with right side adenomatoid solid lesion, and 8 cases presented with double side adenomatoid solid lesion. The proportion of adrenal hyperplasia with unilateral cystic or calcified changes was 21.1%. Nine of the 19 patients underwent operation or fine needle biopsy. The pathology showed 7 adenomas (21-OHD/17α-OHD 5/2) and 2 myelolipomas (21-OHD/17α-OHD 1/1). Four patients were admitted into hospital because of the incidentaloma, while others because of the clinical symptoms. The average follow-up time was 31 months. CT images were rechecked among 7 patients. After the treatment, 1 patient's tumor shrunk, 4 cases had no recurrence, 1 case's tumor disappeared, and the other one case had no change. Symtoms of eleven followed-up patients relieved. Conclusions: The image of adrenal of CAH with adenomatoid adrenal gland is various. It may occur in each type of CAH presented as unilateral or bilateral, adenoma or myelolipoma.

Abstract
OBJECTIVE To investigate the diagnostic value of plasma aldosterone-to-active-renin ratio(ARR)in combination with plasma aldosterone concentration(PAC)in the predication of aldosteronoma(APA). METHODS A total of 85 APA and 155 essential hypertension(EH)patients from January 2012 to December 2014 in Chinese PLA General Hospital were enrolled. The ROC curve was applied to calculate the optimal cut-off points of ARR for APA. RESULTS (1)The optimal cut-off point of supine ARR was 1 707.4(pmol/L)/(μg·L(-1)·h(-1))[61.64(ng/dl)/(μg·L(-1)·h(-1))] with the sensitivity, specificity and accuracy of 89.41%, 80.65% and 83.75%, respectively. The specificity and accuracy of the diagnostic value for APA increased (89.03% and 87.5% respectively) when supine ARR cut-off point were used in combination with supine PAC over 329.4 pmol/L. (2) The optimal cut-off point of upright ARR was 741.5 (pmol/L)/(μg·L(-1)·h(-1))[26.77(ng/dl)/(μg·L(-1)·h(-1) )]with the sensitivity, specificity and accuracy of 85.88%, 91.61% and 89.58%, respectively. Similarly, the specificity and accuracy greatly improved (94.84% and 91.67%, respectively) when upright ARR were applied together with upright PAC over 323.1 pmol/L. CONCLUSIONS Both spine and upright ARR can be used in screening for APA. Moreover, the specificity and accuracy could be improved when ARR and PAC were used together both in the supine and upright position.

Abstract
This study investigated the effects of dietary supplementation with 4 types of oligosaccharides on the growth performance, concentrations of the major odor-causing compounds in excreta and cecal microflora of broilers. Three hundred 21-day-old Archer Abor broilers with an average initial live weight of 702.3 g were randomly divided into 5 dietary treatments: basal diet, basal diet + 5 g/kg of mannan-oligosaccharide (MOS), basal diet + 1.2 g/kg of inulin, basal diet + 1.5 g/kg of fructo-oligosaccharide (FOS), and basal diet +1.25 g/kg of soybean oligosaccharide (SBOS), respectively. Each diet was fed to 6 replicates of 10 birds from d 21 to 42, and body weight and feed intake were recorded. Fresh excreta were sampled from each replicate on d 40, 41, and 42 and stored at -20 °C until further analysis. On d 42, the ceca of killed birds were aseptically removed, and the cecal contents were collected into sterile containers and stored at -80 °C until further analysis. Results showed that feeding inulin, FOS, and SBOS diets resulted in an improvement in daily gain (P < 0.05). Broilers fed the SBOS diet showed lower feed:gain ratio (1.84g:g) than the other groups (P > 0.05). Broilers fed the FOS diet showed the lowest volatile basic nitrogen, pH value, and indole and skatole contents in excreta, and broilers fed the SBOS diet had higher total volatile fatty acids concentrations than control (P < 0.05). The cecal microbial community was measured using the PCR-DGGE, which indicated that the cecal microflora Shannon-wiener index and richness of SBOS-fed broilers were significantly higher than that of the control (P < 0.05). The lowest evenness was recorded in the FOS group, which was significantly lower than the other groups (P < 0.05) except the SBOS group. Based on the sequences of the corresponding 16S rDNA of the DGGE bands, in combination with the contents of the major odor-causing compounds in excreta, it is suggested that uncultured Lachnospiraceae bacterium and Bacteroides sp. were associated with the production of major odor-causing compounds in excreta.

Abstract
Wheat (Triticum aestivum L.), the most widely grown winter cereal crop in China, was grown on 24.3 million hectares in 2012. There was an outbreak of Fusarium head blight in 2012, and it was prevalent in 2013 in North China Plain, the largest area producing winter wheat in China. In 2013, a total of 213 Fusarium graminearum-like isolates were collected from diseased wheat heads in 33 fields in 17 counties in Henan province. The pathogen was isolated from the base of Fusarium-damaged spikelets on potato dextrose agar (PDA) after being surface-sterilized (70% EtOH for 30 s and 3% NaClO for 1.5 min) and rinsed three times in sterilized distilled water. After 3 days, the mycelia were transferred to fresh PDA and purified by the single-spore isolation method. Species were identified based on morphological characteristics (2), and sequence analysis of the translation elongation factor-1α (TEF) and trichothecene 3-O-acetyltransferase (Tri 101) gene (3). The results indicated that F. graminearum species complex (97.2%) is the main causal agent of Fusarium head blight in this region. However, four strains (2%) from the two fields in Jiao Zuo and Xin Xiang counties were found to be identical to F. pseudograminearum. The four (13JZ3-1, 13JZ3-2, 13XX1-2, and 13XX1-6) isolates of F. pseudograminearum were transferred onto carnation leaf agar (CLA) and incubated at 20°C under black light blue illumination. On CLA, macroconidia were abundant, relatively slender, curved to almost straight, commonly six- to seven-septate, and averaged 49.7 × 5.0 μm. Microconidia were not observed. Chlamydospores were observed after 4 weeks. The fungus was initially identified as F. graminearum on the basis of morphology of the asexual stage (2). However, the TEF sequences (Accession nos. KJ863322 to KJ863325) showed 99 to 100% similarity with several F. pseudograminearum sequences (e.g., AF212468, AF212469, and AF212470); the Tri 101 sequences (KJ863326 to KJ863329) showed 99 to 100% similarity with accession nos. AF212615 and AF212616 of F. pseudograminearum. The identification was further confirmed by the F. pseudograminearum species-specific PCR primers (Fp1-1: CGGGGTAGTTTCACATTTCCG and Fp1-2: GAGAATGTGATGACGACAATA) (1). To complete Koch's postulates, the pathogenicity of the fungus was tested by spraying five healthy inflorescences (average of 19 spikelets per spike) of wheat cultivar Zhoumai 18 with a 5-ml suspension (5 × 104 conidia per milliliter). Another five healthy inflorescences were sprayed with sterile distilled water. Plants were placed in a growth chamber with a 12-h photoperiod at 22°C, covered with polyethylene bags that were removed after 2 days. Seven days later, while control inflorescences were asymptomatic, inoculated inflorescences showed a mean of 10 bleached spikelets per spike. By using the methodology described above, the fungus was re-isolated from infected spikelets of inoculated wheat heads but not from the controls. To our knowledge, this is the first report of F. pseudograminearum from diseased wheat heads in China. Further investigation is needed to gain a better understanding of the spatial and temporal dynamics of this new pathogen. References: (1) T. Aoki and K. O'Donnell. Mycologia 91:597, 1999. (2) J. F.

Abstract
The reversed-phase ion pair high performance liquid chromatographic determination of scandium, tin and aluminum with diammonium stilbene-4,4'-bis(1-azo)-3,4-dihydroxybenzene-2,2'-disulfate as precolumn chelating reagent on Spherex C18 column has been investigated with the detection wavelength of 500 nm. Various parameters such as pH, reagent concentration, ion pair reagents, interference of foreign ions have been studied. The mobile phase was methanol-water (40:60, V/V) containing 20 mmol/L acetate buffer of pH 6.0 and 10 mmol/L sodium dodecyl sulfonate. Three complexes could be completely separated within 17 min. The method has been successfully used for the determination of the three metals in mineral samples, with recoveries of 98%, 101%, 103% respectively, and RSD was less than 3.6%. Beer's Law was obeyed over the concentration range 0.01 mg/L-3.80 mg/L, 0.06 mg/L-4.50 mg/L and 0.04 mg/L-3.40 mg/L respectively. The detection limits were 0.9 microgram/L, 1.0 microgram/L and 1.2 micrograms/L for scandium, tin and aluminum when the ratio of signal to noise was 3. Most of other metals did not interfere with the determination. The present method is sensitive and selective.

Abstract
OBJECTIVE Tuberculosis in the abdominal lymph nodes may be difficult to distinguish from lymphomas. This study evaluated specific CT imaging criteria for differentiating these entities. MATERIALS AND METHODS We retrospectively reviewed the anatomic distribution and CT enhancement patterns of disease in 69 patients, 26 (38%) with tuberculosis and 43 (62%) with untreated lymphomas involving abdominal lymph nodes. Of the patients with tuberculosis, five (19%) had disseminated disease and 21 (81%) had nondisseminated disease. Of the patients with lymphomas, 16 (37%) had Hodgkin's disease and 27 (63%) had non-Hodgkin's lymphoma. RESULTS Disseminated and nondisseminated tuberculosis involved predominantly lesser omental, mesenteric, anterior pararenal, and upper paraaortic lymph nodes. Lower paraaortic lymph nodes were involved more often in Hodgkin's disease (15 patients [94%]), non-Hodgkin's lymphoma (24 patients [89%]), and disseminated tuberculosis (five patients [100%]) than in nondisseminated tuberculosis (one patient [5%]). Mesenteric lymph nodes were involved more often in disseminated tuberculosis (four patients [80%]) and nondisseminated tuberculosis (11 patients [52%]) than in Hodgkin's disease (one patient [6%]) (p < .01). Anatomic distribution was not different between disseminated tuberculosis and non-Hodgkin's lymphoma. Tuberculous lymphadenopathy commonly showed peripheral enhancement, frequently with a multilocular appearance, whereas lymphomatous adenopathy characteristically showed homogeneous attenuation (14 patients [87.5%] with Hodgkin's disease and 19 patients [70%] with non-Hodgkin's lymphoma [p < .01]). CONCLUSION Our findings indicate that the anatomic distribution and specific enhancement patterns of lymphadenopathy seen on contrast-enhanced CT can be useful in differentiating between tuberculosis and untreated lymphomas of the abdominal lymph nodes.

Abstract
The human dietary selenium requirement in China has been estimated by various methods. The minimum dietary selenium requirement for the prevention of Keshan disease (KD) was found to be around 17 micrograms/d. On the other hand, an intake of 40 micrograms/d is required to maintain the plasma glutathione peroxidase (GPx) activity at plateau. Hence 40 micrograms/d is considered as the adequate dietary selenium requirement. Studies conducted in a chronic selenosis area indicate that the toxic dietary selenium intake (adverse effect level), which would maintain the characteristic fingernail changes, was approximately 1600 micrograms/d. The mean value of dietary selenium intakes, which enabled the five patients to recover from fingernail lesions, was found to be 819 +/- 126 micrograms/d. At a 95% confidence limit, the lower limit is around 600 micrograms/d. Therefore, 600 and 400 micrograms/d were suggested as the individual daily maximum safe selenium intake and the safe dietary selenium intake, respectively. The results were used in the prevention of Se-related endemic KD and Kashin-Beck disease (KBD).

Abstract
Acute organophosphorus insecticides poisoning (AOIP) is a common medical emergency. There is, at present, a tendency to use high-dose atropine treatment (HDAT). This study aims to test if, during AOIP, HDAT would cause upregulation of muscarinic receptor (M-R). Male mice of the same batch and strain were raised, randomly divided into 3 groups and orally fed with DDVP of the same dose. HDAT for 7 days was given to group A, HDAT for 36 hours was given to group B and low-dose atropine treatment for 36 hours was given to group C. Then radionuclide assay was employed to measure the M-R in the brain and atrium of the mice in each group. The results were that, compared with a control group, the Bmax values (fmol.mg protein-1) of M-R in groups A and B were increased significantly (P < 0.01), while that in group C showed no evident change (P > 0.05). These results indicate that HDAT leads to some physiological change in the body, which may be responsible for the development of poisoning rebound and atropine dependence.

Abstract
In treating patients with acute organophosphorus pesticides poisoning, clinicians pay more attention to poisoning counterattack, while atropine dependence, which resembles counterattack, is not yet fully recognized. The authors analysed 1,039 patients with this kind of poisoning treated in 7 years. Among these cases 157 were dependent on atropine, consisting of 15.1% of the total. The clinical manifestations of the dependence were described. The diagnostic criteria of the dependence and its differential points from counterattack were suggested. It was found that higher occurrence rate of the dependence was seen in patients of younger age, with more severe poisoning and with longer duration and higher total dose of atropine treatment (P < 0.005 respectively). It is considered that its mechanism might be related to increased number of M-receptor and excessive accumulation of acetylcholine. It is suggested that quantitative analysis of relevant receptor be developed.

Abstract
An endemic disease was discovered in 1961 in parts of the population of Enshi County, Hubei Province of the People's Republic of China. During the years of the highest prevalence, from 1961 to 1964, the morbidity was almost 50% in the 248 inhabitants of the five most heavily affected villages; its cause was determined to be selenium intoxication. The most common sign of the poisoning was loss of hair and nails. In areas of high incidence, lesions of the skin, nervous system, and possibly teeth may have been involved. A case is reported of a middle-aged, female hemiplegic, whose illness and death apparently were related to selenosis. Daily dietary intakes of selenium, estimated after the peak prevalence had subsided, averaged 4.99 (range 3.20 to 6.69) mg and hair and blood selenium levels averaged 32.2 and 3.2 micrograms/ml, respectively. Up to 1000x differences occurred when selenium contents of vegetables, cereals, scalp hair, blood, and urine from the selenosis areas were compared with those from Keshan disease (selenium deficiency) areas. The ultimate environmental source of selenium was a stony coal of very high selenium content (average more than 300 micrograms/g; one sample exceeded 80,000 micrograms/g). Selenium from the coal entered the soil by weathering and was available for uptake by crops because of the traditional use of lime as fertilizer in that region. This particular outbreak of human selenosis was due to a drought that caused failure of the rice crop, forcing the villagers to eat more high-selenium vegetables and maize and fewer protein foods.
