Abstract
目的 比较评估初诊时血清游离轻链比值(rFLC)及差值(dFLC)对多发性骨髓瘤(MM)患者预后的价值。 方法 收集整理2012年1月至2016年3月有FLC检测记录的479例初治MM患者的相关临床资料,采用四分位间距法将rFLC、dFLC进行分组。将rFLC分别为3组:≤14.828、14.828~364.597、≥364.597。将dFLC分为3组:≤112.85 mg/L、112.85~2 891.83 mg/L、≥2 891.83 mg/L。随后分别对不同分组进行预后分析比较。使用Kaplan-Meier进行无进展生存(PFS)和总生存期(OS)比较,使用Cox回归进行单因素、多因素预后相关性分析。 结果 不同截断范围rFLC或dFLC患者的OS及PFS差异均有统计学意义。rFLC≤14.828组OS明显优于其他两组(未达到对61个月对47个月,P=0.019);PFS与rFLC 14.828~364.597组相比,差异无统计学意义(P=0.227),与rFLC≥364.597相比,差异有统计学意义(P=0.024)。dFLC≤112.85 mg/L组与其他两组相比PFS、OS差异均有统计学意义。单因素、多因素分析显示rFLC仅与患者OS显著相关,而dFLC与患者OS、PFS均显著相关。4年OS率比较,rFLC≤14.828组4年OS率达90.84%,明显高于其他两组(59.29%、62.26%);dFLC≤112.85 mg/L组4年OS率达89.97%,明显高于其他两组(41.32%、71.95%)(P<0.05)。 结论 对于初治MM患者,不同截断范围的rFLC、dFLC对患者生存预后影响不同。其中rFLC≤14.828或dFLC≤112.85 mg/L,其生存预后差异更为明显,且具有更低的死亡风险,危险比也更低。以此截断值判断患者预后较为理想。

Abstract
Aryl-hydrocarbon receptor interacting protein-like 1 (AIPL1) is essential to stabilize cGMP phosphodiesterase 6 (PDE6) in rod photoreceptors. Mutation of AIPL1 leads to loss of PDE6, accumulation of intracellular cGMP, and rapid degeneration of rods. To understand the metabolic basis for the photoreceptor degeneration caused by excessive cGMP, we performed proteomics and phosphoproteomics analyses on retinas from AIPL1-/- mice at the onset of rod cell death. AIPL1-/- retinas have about 18 times less than normal PDE6a and no detectable PDE6b. We identified twelve other proteins and thirty-nine phosphorylated proteins related to cell metabolism that are significantly altered preceding the massive degeneration of rods. They include transporters, kinases, phosphatases, transferases, and proteins involved in mitochondrial bioenergetics and metabolism of glucose, lipids, amino acids, nucleotides, and RNA. In AIPLI-/- retinas mTOR and proteins involved in mitochondrial energy production and lipid synthesis are more dephosphorylated, but glycolysis proteins and proteins involved in leucine catabolism are more phosphorylated than in normal retinas. Our findings indicate that elevating cGMP rewires cellular metabolism prior to photoreceptor degeneration and that targeting metabolism may be a productive strategy to prevent or slow retinal degeneration.

Abstract
The human macula is more susceptible than the peripheral retina to developing blinding conditions such as age-related macular degeneration, diabetic retinopathy. A key difference between them may be the nature of their Müller cells. We found primary cultured Müller cells from macula and peripheral retina display significant morphological and transcriptomic differences. Macular Müller cells expressed more phosphoglycerate dehydrogenase (PHGDH, a rate-limiting enzyme in serine synthesis) than peripheral Müller cells. The serine synthesis, glycolytic and mitochondrial function were more activated in macular than peripheral Müller cells. Serine biosynthesis is critical in defending against oxidative stress. Intracellular reactive oxygen species and glutathione levels were increased in primary cultured macular Müller cells which were more susceptible to oxidative stress after inhibition of PHGDH. Our findings indicate serine biosynthesis is a critical part of the macular defence against oxidative stress and suggest dysregulation of this pathway as a potential cause of macular pathology.

Abstract
Objective: To investigate the role and related mechanism of resolvin D1 (RvD1) in lung ischemia-reperfusion injury (LIRI) in rats. Methods: Forty male Sprague-Dawley rats, 7-8 weeks, weighing 220-280 g, were divided into 4 groups using a random number table method: sham operation group, lung ischemia reperfusion control group, normal saline group, and RvD1 group. The rat model of LIRI was produced by 45 min of occlusion of the left hilum of lungs followed by 150 min reperfusion. In sham group, no blocking of the left hilum of lung after thoracotomy; Normal saline 2 ml/kg and RvD1 100 μg/kg were injected respectively at 10 min of reperfusion in normal saline group and RvD1 group. Blood samples were collected from the femoral vein for determination of interleukin (IL)-6, tumor necrosis factor (TNF)-α, soluble inter-cell adhesion molecules (sICAM-1) concentrations at 150 min of reperfusion. The rats were sacrificed after collection of blood samples and then lung tissues were taken for observation of the pathological changes and for measurement of lung wet/dry weight ratio (W/D). The the contents of malondialdehyde (MDA), monocyte chemoattractant protein (MCP)-1, macrophage inflammatory protein (MIP)-2 and the activity of myeloperoxidase (MPO) in lung tissues were determined. The protein relative expression of nuclear factor (NF)-κB in lung tissues was detected by Western blot. Lung tissue cell apoptosis was detected with TUNEL method. Results: The plasma level of IL-6, TNF-α, sICAM-1 in normal saline group and RvD1 group were significantly higher than those in the Sham group [(110±7), (100±4) vs (72±3) ng/L, (151±8), (153±6) vs (104±5) ng/L, (2 690±133), (2 760±167) vs (1 953±125) ng/L]. Besides, NF-κB protein relative expression level of lung tissues up-regulated [(0.681±0.033), (0.664±0.024) vs (0.292±0.011)] (all P<0.05). The W/D, apoptosis index, MDA, MCP-1, MIP-2 contents and MPO activity in lung ischemia reperfusion control group, normal saline group and RvD1 group were significantly higher than those in the Sham group [(5.92±0.31), (5.85±0.24), (5.06±0.08) vs (4.14±0.10), (32.9±1.5)%, (31.9±1.3)%, (17.7±1.8)% vs (8.1±0.6)%, (72.1±2.3), (66.7±3.7), (34.0±1.4) vs (22.0±0.8) nmol/mg, (3.99±0.28), (3.86±0.25), (2.66±0.16) vs (1.47±0.17) pg/mg, (9.45±0.53), (9.68±0.62), (7.62±0.22) vs (4.70±0.41) pg/mg, (3.01±0.18), (2.92±0.19), (1.58±0.11) vs (0.98±0.07) U/g] (all P<0.05). The plasma levels of the cytokines mentioned above, the W/D, the apoptosis index, MDA, MCP-1, MIP-2 contents and MPO activity in RvD1 group were significantly lower than those in the lung ischemia reperfusion control group [(63±4) vs (110±7) ng/L, (90±8) vs (151±8) ng/L, (1 835±182) vs (2 690±133) ng/L, (5.06±0.08) vs (5.92±0.31), (17.7±1.8)% vs (32.9±1.5)%, (34.0±1.4) vs (72.1±2.3) nmol/mg, (2.66±0.16) vs (3.99±0.28) pg/mg, (7.62±0.22) vs (9.45±0.53) pg/mg, (1.58±0.11) vs (3.01±0.18) U/g]. Besides, NF-κB protein relative expression level of lung tissues down-regulated [(0.313±0.012) vs (0.681±0.033)] (all P<0.05). Inflammatory cell infiltration in LIRI groups increased significantly, while it was significantly reduced in RvD1 group. Conclusion: RvD1 can effectively alleviate the tissue damage caused by lung ischemia-reperfusion through down-regulating NF-κB expression, relieving inflammatory reaction and oxidative stress, reducing apoptosis in rats.

Abstract
Objective: To investigate the influence of family integrated care (FICare) on the intestinal microbiome of preterm infants in neonatal intensive care unit (NICU). Methods: This was a prospective observational pilot study. A total of 44 preterm infants (23 boys, 52%) admitted to NICU of the Third Xiangya Hospital of Central South University from July, 2015 to June, 2017 were enrolled and divided into FICare, non-FICare groups. Totally 20 term infants (11 boys, 55%) were enrolled into control group, who were sent to the Pediatric Healthcare Clinic for regular health check on postnatal 28-31 days. All infants were free from probiotics after birth and on full enteral feeding. Clinical data of all infants were collected. Two fresh stool specimens of infants in FICare group were collected after 2 weeks of FICare implementation, without use of antibiotics during the prior 1 week. Stool specimens of infants in non-FICare group were collected at the meantime;while for the infants in control group, stool samples were collected at 4 weeks of age. All specimens were stored in-80 ℃ freezer, subsequently investigated by 16 S rRNA sequencing. The results were filtered by paired-end reads software based on RNA overlapping-splicing and tags calculation. Operational taxonomic units (OTU) were analyzed for intestinal microbiome richness. Intestinal microbiome diversity was measured with Shannon index. One-way ANOVA or Kruskal-Wallis H statistic analysis or Chi-square test was used for statistical analysis. Results: There were no significant differences among FICare, non-FICare and control groups in male proportion (52% (11/21) vs. 52% (12/23) vs. 55% (11/20), χ(2)=0.041, P=0.980), in-born ratio (90% (19/21) vs. 87% (20/23) vs. 85% (17/20), χ(2)=0.000, P=1.000), and percentage of infants with Apgar scores<7 at 5 minutes after birth (14% (3/21) vs. 9% (2/23) vs. 5% (1/20), χ(2)=0.120, P=0.729). Similarly, no significant differences were found between FICare and non-FICare groups in terms of gestational age ((29.7±1.8) vs. (29.9±1.7) weeks, t=0.378, P=0.707), birth weight ((1 266±310) vs. (1 326±318) g, t=0.631, P=0.531), median age of initiating feeds (4 vs. 4 days old, Z=0.666, P=0.505), and median age of achieving feeding volume of 120 ml/(kg·d)(13 vs. 11 days old, Z=1.014, P=0.310). However, the breast-feeding rate in FICare group (18/21, 86%) was significantly higher than that in non-FICare group (8/23, 35%) (t=11.780, P=0.001). The medium Shannon index was 0.72 (0.27,2.66), 0.61 (0.18,1.83), and 0.52 (0.08,1.71) in control, FICare, and non-FICare groups, respectively, without significant difference (H=1.823, P=0.402). The domain flora was Lactobacillus Firmicutes in all three groups, which was of the highest percentage in FICare group (71.6±5.4)%, followed by control group (65.4±6.6)% and non-FICare group (55.6±8.8)%, with a significant difference (F=27.919, P=0.000). Conclusions: FICare can improve the richness and diversity of intestinal microbiome, stimulate the establishment of flora close to those of normal breast-feeding infants in preemies in NICU, making its establishment being more similar to normal term breast-feeding infants. This effect might be caused by the increased skin-to-skin contact and increased fresh breast-milk-feeding in FICare.

Abstract
Objective: To analyze the influence of different thyroid stimulating hormone (TSH) cut-offs to diagnose subclinical hypothyroidism (SCH) in the first trimester of gestation. Methods: A total of 896 pregnant women were enrolled in Peking University International Hospital between October 2016 and March 2018. Among them, 421 pregnant women with single fetus who were conformed to the criteria of National Academy of Clinical Biochemistry (NACB), without adverse pregnancy outcomes and obstetric complications, were selected to establish their self-sequential longitudinal reference ranges of thyroid function. Then, SCH was diagnosed in the first trimester, using different TSH cutoffs, such as the upper limit of the first trimester-specific reference range, 4.0 mU/L recommended by the 2017 Guidelines of American Thyroid Association (ATA), 5.17 mU/L (Roche reagent) recommended by 2012 Guidelines of Chinese Society of Endocrinology and Chinese Society of Perinatal Medicine, and 2.5 mU/L recommended by 2011 Guidelines of ATA, respectively. Results: The TSH reference range was 0.12-4.16 mU/L in the first trimester. Using TSH>4.16, 4.0, 5.17 and 2.5 mU/L to diagnose SCH in the first trimester, the prevalence rates were 4.35% (39/896), 5.92% (53/896), 1.56% (14/896) and 20.87% (187/896), respectively. There was no statistically significant difference between the prevalence rates of SCH using the TSH upper reference limit of 4.0 mU/L and 4.16 mU/L (P=0.134). When TSH was defined as>4.0 mU/L to diagnose SCH, the sensitivity, specificity and Youden index was 97.4%, 98.2%, and 0.956, respectively. Conclusions: The TSH upper reference limit of 4.0 mU/L recommended by 2017 Guidelines of ATA can be used as a cut-off to diagnose SCH in first trimester for the areas without trimester-specific reference ranges for TSH in China.

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

Abstract
Objective: To evaluate the efficacy and safety of Saccharomyces boulardii Sachets combined with bismuth quadruple therapy for initial Helicobacter pylori(H.pylori) eradication. Methods: From March 2014 to March 2015, 240 participants from the third hospital of Hebei medical university with H. pylori infection were recruited and randomized into three groups: Quadruple therapy group received bismuth potassium citrate 220 mg bid + Rabeprazole 10 mg bid + amoxicillin 1 000 mg bid+ furazolidone 100 mg bid for 10 days. Short-term group and long-term group received the same quadruple therapy for 10 days as above, as well as Saccharomyces boulardii Sachets 500 mg bid for 14 days and 28 days, respectively. H. pylori eradication was confirmed by (13)C/(14)C-UBT at least 4 weeks after completion of therapy. And side effects were investigated during the therapy. Results: The H. pylori eradication rates in quadruple therapy, short-term and long-term group were 80%, 87.5% and 87.5% by ITT analysis (P=0.321) and 92.8%, 94.6% and 95.9% by PP analysis (P=0.717), respectively. The overall side effect rate and occurrence of diarrhea and abdominal distension were significantly lower in short-term or long-term group as compared with quadruple therapy group(P=0.007, 0.003, 0.004), but there was no significant difference between the two probiotics groups. Conclusions: Both short and long-term Saccharomyces boulardii Sachets reduced the overall side effect rate and occurrence of diarrhea or abdominal distension when combined with bismuth quadruple therapy for initial H. pylori eradication and no difference was observed in efficacy or safety between the two groups.

Abstract
Tuberculosis, smoking, and alcohol drinking are major public health and social issues worldwide. We investigated the joint effect of smoking plus alcohol drinking on TB treatment. Retrospective study was conducted among TB patients in 49 units from eight provinces in China. All patients enrolled were classified into four groups according to their smoking and/or alcohol status. Current smokers plus drinkers belonged to group 1; ex-smokers plus ex-drinkers were in group 2; current smokers and ex-drinkers, current smokers and never drinkers, ex-smokers and current drinkers, ex-smokers and never drinkers, never smokers and current drinkers, and never smokers and ex-drinkers belonged to group 3; while the never smokers plus never drinkers were in group 4. We used a chi-square test to compare adverse drug reaction, lesions absorption and cavities of lung, sputum culture at the end of the second month, and treatment outcomes among the four groups. Among the 1256 participants enrolled in the study, 6.1% (76/1256) were current smokers plus drinkers; 25.9% (325/1256) were ex-smokers plus drinkers; 29.1% (366/1256) were current/never/ex-smokers and/or drinkers, and 38.9% (489/1256) were never smokers plus drinkers, respectively. Compared to the never smokers and drinkers, smoker plus drinker TB patients were more likely to experience adverse drug reaction (x2 = 8.480, P = 0.037), less proportion of lesions absorption in lungs (x2 = 10.330, P = 0.016), lower proportion of culture conversion (x2 = 18.83, P = 0.04), and more unfavorable outcomes. Smoking plus alcohol drinking adversely affect response against TB treatment, which increase adverse drug reactions, sputum culture-positive rate at the end of the second month, and failure rate of pulmonary tuberculosis patients.

Abstract
Objective: To analyze and evaluate the effectiveness of individualized treatment regimen in the therapy of smear-positive retreatment pulmonary tuberculosis with mono-and poly-drug resistance, and therefor to provide information on how to develop rational individualized regimen for retreatment tuberculosis cases with drug resistance. Methods: This was a multi-centered, prospective cohort study. Totally 254 cases of sputum positive tuberculosis with previous treatment history during the period from July 1, 2009 to August 30, 2016 were included in the analysis. All the cases were randomly divided into 3 groups and received therapy after randomization into treatment groups. After 3 months, cases with multidrug resistant tuberculosis, extensively drug-resistant tuberculosis, non-tuberculosis mycobacterial infection and those with smear-positive but culture-negative tuberculosis were excluded according to result of sputum culture and drug susceptibility test (DST). In treatment group A (individualized treatment group), 86 cases with an average age of (42.1±13.7) years for men and (38.5±12.8) years for women, were treated with individualized regimen, which allowed drug replacement on the basis of standard regimen (2SHRZE/6HRE) according to DST result. Treatment duration was recalculated after drug replacement and the total length should be 12 months or more. If the DST result did not show drug resistance, the patients would continue the 8 months' standard treatment. In treatment group B (intensified retreatment regimen group), 86 cases with an average age of (43.2±14.2) years for man and (37.9±14.1) years for women, received intensified retreatment regimen (2HL(2)EZS/2HL(2)EZS(3)/4HL(2)E). The dose for H was 0.3 g/d for patients with body weight <50 kg, and 0.4~0.5 g/d for higher body weight (≥50 kg); The doses for L(2,)E and Z were 0.6 g, 2/w; 0.75, 1/d and 0.5g, 3/d. In treatment group C (standard treatment group), 82 cases with an average of (42.5±11.9) years for man and (38.6±12.8) years for women, were treated with standardized regimen recommended by national tuberculosis program (2HREZS/6HRE). In both group B and C, the total treatment duration was 8 months and the drugs were not replaced for mono-and poly-drug resistance. Treatment outcomes of the 3 groups were analyzed, the status of drug replacement in group A was analyzed, and the adjustment of dose of H and R according to patients' body weight was observed. SPSS 19.0 was used for data analysis. Results: The treatment cure rates for group A, B and C were 73.3%(63/86), 76.7%(66/86) and 50%(41/82), and the treatment success rates were 80.2%(69/86), 84.9%(73/86) and 62.2%(51/82) respectively. Treatment failure was 8.1%(7/86), 4.7%(4/86) and 19.5%(16/82) in 3 groups. There were significant differences in the above indicators for group A and B in comparison with group C(χ(2)=13.127, P=0.001). However, there was no difference observed between group A and B(χ(2)=0.646, P=0.422). In group A, tuberculosis specialized hospitals using regular doses for R was only 38.7%(12/31). After 3 years' follow-up, no-relapse-success for group A was 66.7% (10/15). Conclusions: Inappropriate individualized treatment would increase treatment failure for retreatment tuberculosis. Higher doses of H and R and prolonged extensive therapy phase could contribute to increased treatment success.

Abstract
Retinal pigment epithelial (RPE) degeneration is potentially involved in the pathogenesis of several retinal degenerative diseases. mTORC1 signaling is shown as a crucial regulator of many biological processes and disease progression. In this study, we aimed at investigating the role of mTORC1 signaling in RPE degeneration. Methods: Western blots were conducted to detect mTORC1 expression pattern during RPE degeneration. Cre-loxP system was used to generate RPE-specific mTORC1 activation mice. Fundus, immunofluorescence staining, transmission electron microscopy, and targeted metabolomic analysis were conducted to determine the effects of mTORC1 activation on RPE degeneration in vivo. Electroretinography, spectral-domain optical coherence tomography, and histological experiments were conducted to determine the effects of mTORC1 activation on choroidal and retinal function in vivo. Results: RPE-specific activation of mTORC1 led to RPE degeneration as shown by the loss of RPE-specific marker, compromised cell junction integrity, and intracellular accumulation of lipid droplets. RPE degeneration further led to abnormal choroidal and retinal function. The inhibition of mTORC1 signaling with rapamycin could partially reverse RPE degeneration. Targeted metabolomics analysis further revealed that mTORC1 activation affected the metabolism of purine, carboxylic acid, and niacin in RPE. Conclusion: This study revealed that abnormal activation of mTORC1 signaling leads to RPE degeneration, which could provide a promising target for the treatment of RPE dysfunction-related diseases.

Abstract
Involvement of flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN) in cellular homeostasis has been well established for tissues other than the retina. Here, we present an optimized method to effectively extract and quantify FAD and FMN from a single neural retina and its corresponding retinal pigment epithelium (RPE). Optimizations led to detection efficiency of 0.1 pmol for FAD and FMN while 0.01 pmol for riboflavin. Interestingly, levels of FAD and FMN in the RPE were found to be 1.7- and 12.5-fold higher than their levels in the retina, respectively. Both FAD and FMN levels in the RPE and retina gradually decline with age and preceded the age-dependent drop in the functional competence of the retina as measured by electroretinography. Further, quantifications of retinal levels of FAD and FMN in different mouse models of retinal degeneration revealed differential metabolic requirements of these two factors in relation to the rate and degree of photoreceptor degeneration. We also found twofold reductions in retinal levels of FAD and FMN in two mouse models of diabetic retinopathy. Altogether, our results suggest that retinal levels of FAD and FMN can be used as potential markers to determine state of health of the retina in general and more specifically the photoreceptors.

Abstract
The retina is one of the most metabolically active tissues in the body and utilizes glucose to produce energy and intermediates required for daily renewal of photoreceptor cell outer segments. Glucose transporter 1 (GLUT1) facilitates glucose transport across outer blood retinal barrier (BRB) formed by the retinal pigment epithelium (RPE) and the inner BRB formed by the endothelium. We used conditional knockout mice to study the impact of reducing glucose transport across the RPE on photoreceptor and Müller glial cells. Transgenic mice expressing Cre recombinase under control of the Bestrophin1 ( Best1) promoter were bred with Glut1flox/flox mice to generate Tg-Best1-Cre:Glut1flox/flox mice ( RPEΔGlut1). The RPEΔGlut1 mice displayed a mosaic pattern of Cre expression within the RPE that allowed us to analyze mice with ~50% ( RPEΔGlut1m) recombination and mice with >70% ( RPEΔGlut1h) recombination separately. Deletion of GLUT1 from the RPE did not affect its carrier or barrier functions, indicating that the RPE utilizes other substrates to support its metabolic needs thereby sparing glucose for the outer retina. RPEΔGlut1m mice had normal retinal morphology, function, and no cell death; however, where GLUT1 was absent from a span of RPE greater than 100 µm, there was shortening of the photoreceptor cell outer segments. RPEΔGlut1h mice showed outer segment shortening, cell death of photoreceptors, and activation of Müller glial cells. The severe phenotype seen in RPEΔGlut1h mice indicates that glucose transport via the GLUT1 transporter in the RPE is required to meet the anabolic and catabolic requirements of photoreceptors and maintain Müller glial cells in a quiescent state.

Abstract
Objective: The main purpose of this paper is to evaluate the level of serum 25-hydroxyvitamin D (25-OH-D) and clinical significance in patients with Takayasu's Arteritis (TA). Methods: A total of 62 untreated TA patients (TA group) and 60 healthy people (control group) were enrolled. The level of serum 25-OH-D were measured and compared between groups. The correlations of 25-OH-D level with related indicators were analyzed. Results: Lower concentrations of serum 25-OH-D were detected in TA patients compared with healthy subjects[(11.8±4.7) μg/L versus (23.2±8.3) μg/L](P<0.001). In active stage group, the 25-(OH)-D level of TA were significantly lower than that in remission stage group[(10.5±4.3) μg/L vs (13.3±4.9) μg/L](P=0.021). In all patients with TA, serum 25-OH-D correlated negatively with interleukin (IL)-6 (r=-0.296, P=0.023). There was no correlation between serum 25-OH-D level and C-reactive protein , erythrocyte sedimentation rate , National Institutes of Health Score, Indian Takayasu Clinical Activity Score 2010, and anti-tumor necrosis factor (TNF)-alpha antibody. Conclusion: A high prevalence of vitamin D deficiency was observed in patients with TA. The serum 25-OH-D level were negatively correlated with IL-6.

Abstract
Objective: To discuss the affect of glycosylated hemoglobin (HbA1c) level for the onset of nonalcoholic fatty liver disease (NAFLD) in cohort population. Methods: An epidemiological survey of the relationship between HbA1c and NAFLD conducted in 2012 was based at cohort baseline, and three follow-up sessions conducted in 2013, 2014 and 2015. In total 2 811 subjects were included in the study after exclusion of NAFLD patients at baseline and those who lost their lives due to relocation, and death. The Cox proportional hazard model was used to analyze the relationship between glycosylated hemoglobin and other risk factors of NAFLD. Continuous variables were compared using the t-test or the Mann-Whitney test. χ (2)-test was used for the measurement of categorical data. Results: A total of 2 811 subjects with mean age of 59 (58.2±9.8) years old, including 1 664 males and 1 147 females. Age, waist circumference, body mass index, systolic blood pressure, γ-glutamyltransferase and fasting blood glucose level of HbA1c abnormal group were higher than normal group. The incidence of NAFLD in the abnormal HbA1c level group (25.4%) was higher than normal group (14.9 %), and diastolic blood pressure, high-density lipoprotein cholesterol was lower than normal group and the differences were statistically significant. During the three follow-up intervals, there were 440 new cases of NAFLD, consisting 285 males and 155 females with cumulative incidence of 15.7% (440/2 811). Multivariate Cox regression analysis showed that patients with elevated HbA1c had a higher risk of developing NAFLD (HR 1.796; 95% CI 1.335~2.418; P < 0.01), and the increased HbA1c level after adjustment for gender, age, and metabolic syndrome-related factors remained an independent risk factors for NAFLD (HR 1.580; 95.0% CI 1.161-2.152; P < 0.01). Conclusion: An elevated HbA1c levels have a positive predictive value for the onset of NAFLD.

Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyps (CRSwNP) remains a challenging clinical problem due to its propensity for recurrence. However, data on the frequency of CRSwNP recurrence after surgery in China are rare. METHODS 78 CRSwNP patients undergoing functional endoscopic sinus surgery were followed-up for 8 years and classified into recurrent and non-recurrent groups. A cluster analysis of the CRSwNP based on inflammatory endotypes was performed, and the endotypes were secondarily matched with clinical phenotypes. RESULTS The recurrence rate of CRSwNP in Southwest China was 21.8% over 8 years post-surgery. The CRSwNP was classified into 4 clusters: cluster 1 (higher expression of IL-5, IgE, and ECP and high positivity rate for SE-IgE); cluster 2 (higher concentrations of IL-6, IL-8 and MPO); cluster 3 (higher concentrations of TNF-alpha; and IFN-gamma); and cluster 4 (higher expression of IL-17). Cluster 1 (type-2 inflammation) exhibited the highest recurrence rate, co-morbid asthma and atopy. Notably, the ECP/MPO ratio increased significantly in patients with non-type-2 recurrent CRSwNP 8 years after the first surgery. CONCLUSION Different inflammatory endotypes of CRSwNP exhibited clearly different prognoses. The type-2 subgroup had high recurrence and co-morbid asthma rates comparable to the rates reported in Western countries.

Abstract
Purpose: Urbanization is causing an increasingly negative effect on public health in China. This study was established to examine the associations between socio-economic and environmental exposures and the potential impact of gene-environment interactions and cancer risk of urban population in Chongqing, China. Participants: The cohort was established in Beibei District of Chongqing in southwest China. Between March 2016 and December 2016, we enrolled 57,332 adults who were 40-69 years of age, and collected baseline data on demographic information, socio-economic status, lifestyle, family and personal disease histories through face-to-face interviews using a standardized questionnaire. Regular follow-up including face-to-face interviews will take place every 5 years. Findings to date: Ninety-nine percent (56658/57332) of the participants completed the baseline assessment. The eligible participants had a mean age of 54.8 years, and 51.42% were females. Nearly three-fifths of participants having a normal BMI (18.5 to 23.9 kg/m2) and one-third being overweight (24.0 to 27.9 kg/m2). Among males, 29.58% were smokers and 21.08% were alcohol users. Among females, 1.49% were smokers and 1.66% were alcohol users. Among all participants, 7.03% of males and 9.08% of females reported their family history of cancer. Future plans: The relationships of modifiable risk factors with the cancer risk will be analyzed. Meanwhile, participants will be closely tracked to minimize loss to follow-up. We plan to construct a risk prediction model on cancer and verify the prediction model by genome-wide association studies (GWAS). The successful completion of this cohort study will allow for better targeting of cancer screening to those at highest risk in urban population of China and provide clinicians and policymakers with a practical predication rule.

Abstract
Aging is a major risk factor for age-related ocular diseases including age-related macular degeneration in the retina and retinal pigment epithelium (RPE), cataracts in the lens, glaucoma in the optic nerve, and dry eye syndrome in the cornea. We used targeted metabolomics to analyze metabolites from young (6 weeks) and old (73 weeks) eyes in C57 BL6/J mice. Old mice had diminished electroretinogram responses and decreased number of photoreceptors in their retinas. Among the 297 detected metabolites, 45-114 metabolites are significantly altered in aged eye tissues, mostly in the neuronal tissues (retina and optic nerve) and less in cornea, RPE/choroid, and lens. We noted that changes of metabolites in mitochondrial metabolism and glucose metabolism are common features in the aged retina, RPE/choroid, and optic nerve. The aging retina, cornea, and optic nerve also share similar changes in Nicotinamide adenine dinucleotide (NAD), 1-methylnicotinamides, 3-methylhistidine, and other methylated metabolites. Metabolites in taurine metabolism are strikingly influenced by aging in the cornea and lens. In conclusion, the aging eye has both common and tissue-specific metabolic signatures. These changes may be attributed to dysregulated mitochondrial metabolism, reprogrammed glucose metabolism and impaired methylation in the aging eye. Our findings provide biochemical insights into the mechanisms of age-related ocular changes.

Abstract
Critical ultrasonography(CUS) is different from the traditional diagnostic ultrasound, the examiner and interpreter of the image are critical care medicine physicians. The core content of CUS is to evaluate the pathophysiological changes of organs and systems and etiology changes. With the idea of critical care medicine as the soul, it can integrate the above information and clinical information, bedside real-time diagnosis and titration treatment, and evaluate the therapeutic effect so as to improve the outcome. CUS is a traditional technique which is applied as a new application method. The consensus of experts on critical ultrasonography in China released in 2016 put forward consensus suggestions on the concept, implementation and application of CUS. It should be further emphasized that the accurate and objective assessment and implementation of CUS requires the standardization of ultrasound image acquisition and the need to establish a CUS procedure. At the same time, the standardized training for CUS accepted by critical care medicine physicians requires the application of technical specifications, and the establishment of technical specifications is the basis for the quality control and continuous improvement of CUS. Chinese Critical Ultrasound Study Group and Critical Hemodynamic Therapy Collabration Group, based on the rich experience of clinical practice in critical care and research, combined with the essence of CUS, to learn the traditional ultrasonic essence, established the clinical application technical specifications of CUS, including in five parts: basic view and relevant indicators to obtain in CUS; basic norms for viscera organ assessment and special assessment; standardized processes and systematic inspection programs; examples of CUS applications; CUS training and the application of qualification certification. The establishment of applied technology standard is helpful for standardized training and clinical correct implementation. It is helpful for clinical evaluation and correct guidance treatment, and is also helpful for quality control and continuous improvement of CUS application.

Abstract
Objective: To investigate the efficacy and safety of Compound Lactobacillus Tablets or Saccharomyces boulardii Sachets combining with bismuth quadruple therapy for Helicobacter pylori(H.pylori) eradication. Methods: A total of 360 H. pylori- infected patients were enrolled and randomly assigned into three groups. Group A received esomeprazole 20 mg bid+ bismuth potassium citrate 220 mg bid+ amoxicillin 1 000 mg bid+ furazolidone 100 mg bid for 10 days. Group B or group C received the same quadruple therapy for 10 days as group A, as well as Compound Lactobacillus Tablets 1 000 mg tid or Saccharomyces boulardii Sachets 500 mg bid for 14 days. Drug-related side effects and adverse reactions were collected during the therapy, and H. pylori eradication results were confirmed by (13)C/(14)C-UBT at least 4 weeks after cessation of therapy. Results: The H. pylori eradication rates in group A, B and C were 81.7%, 84.2% and 85.0% by ITT analysis (P=0.768) and 92.5%, 90.1% and 93.6% by PP analysis (P=0.770), respectively. The overall side effects and adverse reactions rates (P=0.008) and occurrence of diarrhea (P<0.001) were significantly lower in group B than group A. The overall side effect rates (P=0.003) and occurrence of diarrhea (P<0.001), abdominal distension (P=0.004) and constipation(P=0.002) were significantly lower in group C than group A. There was no significant difference in side effects and adverse reactions rates between the two probiotics groups. Conclusions: Both Compound Lactobacillus Tablets and Saccharomyces boulardii Sachets, combining with bismuth quadruple therapy, reduced the overall side effects and adverse reactions rates for H. pylori eradication. Moreover, the former can reduce the incidence of diarrhea, and the latter can reduce the incidence of diarrhea, abdominal distension and constipation.

Abstract
Objective: To study the relationship between the weight change trend of initial treatment patients with pulmonary tuberculosis and the dose change trend of isoniazid, and therefore to analyze the appropriate dose of isoniazid. Methods: Data of initial treatment inpatients with pulmonary tuberculosis from May 1955 to December 2012 were retrospectively analyzed. Elderly patients with pulmonary tuberculosis, patients with drug-resistant tuberculosis, extrapulmonary tuberculosis and those with complications were excluded from the study. The time period was separated as 20th century 1950s to 1960s, 1970s, 1980s, 1990s, 21th century 2000s and 2010s. Samples were selected in each year and month between 1950s to 1960s and 1970s. After 1980s, samples of 1 year were taken from each 5 years. The sex, age and weight for every patient were collected, as well as the dose of isoniazid of every inpatient on a day in therapeutic regimen. Meanwhile, the weight change trend of the patients in different ages and the dose change trend of isoniazid were compared. The total number of cases was 1 398, with 924 males and 474 females, averaging (36.7±14.4) years old. Results: The weight of the patients increased when it was compared between that in 1950s to 1960s, 1970s or 1980s and that in 2000s, with a increasing weight of 3 kg, 3.5 kg and 3 kg respectively. The difference showed statistical significance (P<0.003). The difference was also significant when the weight in 70s was compared with that in 2010s (P=0.002). The therapeutic dose of isoniazid remained invariable regardless of the weight change. At 1990s, 2000s and 2010s, the dose of isoniazid per kilogram of body weight would reduce to 0.005 4 g, 0.005 2 g and 0.0054 g relative to patients' weight increase, and the difference was statistically significant (P<0.001). Conclusions: The weight of pulmonary tuberculosis inpatients increased in recent 60 years. The weight has a close relation with the dose of isoniazid. A fixed dose of isoniazid (0.3 g/d) regardless of the weight change could result in low blood drug concentration . To avoid tolerance of isoniazid and increase the cure rates of pulmonary tuberculosis, the dosage of isoniazid should be increased based on the weight increase of patients.

Abstract
The primary energy substrate of the lens is glucose and uptake of glucose from the aqueous humor is dependent on glucose transporters. GLUT1, the facilitated glucose transporter encoded by Slc2a1 is expressed in the epithelium of bovine, human and rat lenses. In the current study, we examined the expression of GLUT1 in the mouse lens and determined its role in maintaining lens transparency by studying effects of postnatal deletion of Slc2a1. In situ hybridization and immunofluorescence labeling were used to determine the expression and subcellular distribution of GLUT1 in the lens. Slc2a1 was knocked out of the lens epithelium by crossing transgenic mice expressing Cre recombinase under control of the GFAP promoter with Slc2a1loxP/loxP mice to generate Slc2a1loxP/loxP;GFAP-Cre+/0 (LensΔGlut1) mice. LensΔGlut1 mice developed visible lens opacities by around 3 months of age, which corresponded temporally with the total loss of detectable GLUT1 expression in the lens. Spectral domain optical coherence tomography (SD-OCT) imaging was used to monitor the formation of cataracts over time. SD-OCT imaging revealed that small nuclear cataracts were first apparent in the lenses of LensΔGlut1 mice beginning at about 2.7 months of age. Longitudinal SD-OCT imaging of LensΔGlut1 mice revealed disruption of mature secondary fiber cells after 3 months of age. Histological sections of eyes from LensΔGlut1 mice confirmed the disruption of the secondary fiber cells. The structural changes were most pronounced in fiber cells that had lost their organelles. In contrast, the histology of the lens epithelium in these mice appeared normal. Lactate and ATP were measured in lenses from LensΔGlut1 and control mice at 2 and 3 months of age. At 2 months of age, when GLUT1 was still detectable in the lens epithelium, albeit at low levels, the amount of lactate and ATP were not significantly different from controls. However, in lenses isolated from 3-month-old LensΔGlut1 mice, when GLUT1 was no longer detectable, levels of lactate and ATP were 50% lower than controls. Our findings demonstrate that in vivo, the transparency of mature lens fiber cells was dependent on glycolysis for ATP and the loss of GLUT1 transporters led to cataract formation. In contrast, lens epithelium and cortical fiber cells have mitochondria and could utilize other substrates to support their anabolic and catabolic needs.

Abstract
Objective: To evaluate the impact of KIT D816 mutation on the salvage therapy in relapsed acute myeloid leukemia (AML) with t(8;21) translocation. Method: The characteristics of the first relapsed AML with t(8;21) translocation from 10 hospitals were retrospectively collected, complete remission (CR(2)) rate after one course salvage chemotherapy and the relationship between KIT mutation and CR(2) rate was analyzed. Results: 68 cases were enrolled in this study, and 30 cases (44.1%) achieved CR(2). All patients received KIT mutation detection, and KIT D816 mutation was identified in 26 cases. The KIT D816 positive group had significantly lower CR(2) compared with non-KIT D816 group (23.1% vs 57.1%, χ(2)=7.559, P=0.006), and patients with longer CR(1) duration achieved significantly higher CR(2) than those with CR(1) duration less than 12 months (74.1% vs 31.9%, χ(2)=9.192, P=0.002). KIT D816 mutation was tightly related to shorter CR(1) duration. No significant difference of 2 years post relapse survival was observed between KIT D816 mutation and non-KIT D816 mutation group. Conclusion: KIT D816 mutation at diagnosis was an adverse factor on the salvage therapy in relapsed AML with t(8;21) translocation, significantly related to shorter CR1 duration, and can be used for prediction of salvage therapy response. KIT D816 mutation could guide the decision-making of salvage therapy in relapsed AML with t(8;21) translocation.

Abstract
Feed represents two-thirds of the total costs of poultry production, especially in developing countries. Improvement in feed efficiency would reduce the amount of feed required for production (growth or laying), the production cost, and the amount of nitrogenous waste. The most commonly used measures for feed efficiency are feed conversion ratio (FCR) and residual feed intake (RFI). As a more suitable indicator assessing feed efficiency, RFI is defined as the difference between observed and expected feed intake based on maintenance and growth or laying. However, the genetic and biological mechanisms regulating RFI are largely unknown. Identifying molecular mechanisms explaining divergence in RFI in laying ducks would lead to the development of early detection methods for the selection of more efficient breeding poultry. The objective of this study was to identify duodenum genes and pathways through transcriptional profiling in 2 extreme RFI phenotypes (HRFI and LRFI) of the duck population. Phenotypic aspects of feed efficiency showed that RFI was strongly positive with FCR and feed intake (FI). Transcriptomic analysis identified 35 differentially expressed genes between LRFI and HRFI ducks. These genes play an important role in metabolism, digestibility, secretion, and innate immunity including (), (), (), β (), and (). These results improve our knowledge of the biological basis underlying RFI, which would be useful for further investigations of key candidate genes for RFI and for the development of biomarkers.

Abstract
Metabolomics studies in the retina and retinal pigment epithelium (RPE) in animal models or postmortem donors are essential to understanding the retinal metabolism and to revealing the underlying mechanisms of retinal degenerative diseases. We have studied how different methods of euthanasia (CO2 or cervical dislocation) different isolation procedures and postmortem delay affect metabolites in mouse retina and RPE/choroid using LC MS/MS and GC MS. Compared with cervical dislocation, CO2 exposure for 5 min dramatically degrades ATP and GTP into purine metabolites in the retina while raising intermediates in glucose metabolism and amino acids in the RPE/choroid. Isolation in cold buffer containing glucose has the least change in metabolites. Postmortem delay time-dependently and differentially impacts metabolites in the retina and RPE/choroid. In the postmortem retina, 18% of metabolites were changed at 0.5 h (h), 41% at 4 h and 51% at 8 h. However, only 6% of metabolites were changed in the postmortem RPE/choroid and it steadily increased to 20% at 8 h. Notably, both postmortem retina and RPE/choroid tissue showed increased purine metabolites. Storage of eyes in cold nutrient-rich medium substantially blocked the postmortem change in the retina and RPE/choroid. In conclusion, our study provides optimized methods to prepare fresh or postmortem retina and RPE/choroid tissue for metabolomics studies.

Abstract
BACKGROUND Traumatic brain injury (TBI) is a common occurrence following gastrointestinal dysfunction. Recently, more and more attentions are being focused on gut microbiota in brain and behavior. Glucagon-like peptide-1 (GLP-1) is considered as a mediator that links the gut-brain axis. The aim of this study was to explore the neuroprotective effects of Clostridium butyricum (Cb) on brain damage in a mouse model of TBI. METHODS Male C57BL/6 mice were subjected to a model of TBI-induced by weight-drop impact head injury and were treated intragastrically with Cb. The cognitive deficits, brain water content, neuronal death, and blood-brain barrier (BBB) permeability were evaluated. The expression of tight junction (TJ) proteins, Bcl-2, Bax, GLP-1 receptor (GLP-1R), and phosphorylation of Akt (p-Akt) in the brain were also measured. Moreover, the intestinal barrier permeability, the expression of TJ protein and GLP-1, and IL-6 level in the intestine were detected. RESULTS Cb treatment significantly improved neurological dysfunction, brain edema, neurodegeneration, and BBB impairment. Meanwhile, Cb treatment also significantly increased the expression of TJ proteins (occludin and zonula occluden-1), p-Akt and Bcl-2, but decreased expression of Bax. Moreover, Cb treatment exhibited more prominent effects on decreasing the levels of plasma d-lactate and colonic IL-6, upregulating expression of Occludin, and protecting intestinal barrier integrity. Furthermore, Cb-treated mice showed increased the secretion of intestinal GLP-1 and upregulated expression of cerebral GLP-1R. CONCLUSIONS Our findings demonstrated the neuroprotective effect of Cb in TBI mice and the involved mechanisms were partially attributed to the elevating GLP-1 secretion through the gut-brain axis.

Abstract
Essentials The best imaging modality for joint blood detection in hemophilia is unknown. Blood appearance and detection thresholds were studied with ultrasound and conventional MRI. Ultrasound is sensitive to low volume and concentration of blood, whereas conventional MRI is not. The findings establish the validity of ultrasound for rapid bleed detection in hemophilia care. SUMMARY Background There is increasing demand for musculoskeletal ultrasound (MSKUS) to detect hemophilic joint bleeding, but there is uncertainty regarding blood detection concentration thresholds or if magnetic resonance imaging (MRI) is more accurate. Aims Compare the sensitivity of blood detection by MSKUS and MRI. Methods Increasing blood concentrations in plasma were imaged with MSKUS and MRI 1-2 h, 3-4 days and 7 days after blood withdrawal in vitro, and after injection into cadaveric pig joints. Additionally, effusions in the joints of two patients with hemophilia joints were imaged, followed by aspiration. MSKUS was performed using an 8-18-MHz linear transducer; MRI was performed at 3T using T1-weighted and T2-weighted fat-suppressed sequences. Images were reviewed by a hematologist certified in MSKUS and a musculoskeletal radiologist. Results MSKUS permitted the detection of blood in vitro and in pig joint spaces at concentrations as low as 5%, demonstrated by the presence of echogenic signals that were absent with plasma alone. In contrast, no differences between fluids were discernible on the T1-weighted or T2-weighted MRI images. Results were confirmed in the two patients with hemophilia. Blood clots demonstrated varying and dynamic echogenicity patterns over time and, using MRI, were visualized best with T2 sequences. Conclusion MSKUS is extremely sensitive in detecting low concentrations of intra-articular blood and in discriminating between bloody and non-bloody fluid, whereas conventional MRI is not. These observations demonstrate the advantages of MSKUS over MRI in detecting intra-articular blood, and show that MSKUS is ideal for rapid bleed detection in the clinic.

Abstract
We demonstrate that a bipolar non-volatile resistive switching behaviour with negative differential resistance (NDR) effect is realized in a Cu/BaTiO3/Ag device, which was deposited on a Si substrate via magnetron sputtering equipment. We suggest that the bipolar resistive switching is dominated by the trapping/detrapping of electrons at the BaTiO3-Cu interface. In addition, we demonstrate that the device exhibits good performance, including a large on/off ratio, high reliability and long retention time. Therefore, BaTiO3 may become a good candidate for application in resistive switching random access memory (RRAM) devices.

Abstract
AIM MICAL2, a cytoskeleton dynamics regulator, is identified associated with survival and metastasis of several types of cancers recently. This study was designed to investigate the role of MICAL2 in breast cancer cell migration as well as its underlying mechanisms. METHODS The relationship between MICAL2 and EGF/EGFR signalling was analysed by gene overexpression and knock-down techniques. Cell migration was measured by wound-healing assays. Activation of EGF/EGFR signalling pathways were evaluated by immunofluorescence, qPCR, Western blotting and zymography techniques. Rac1 activity was assessed by pull-down assay. Correlation of MICAL2 and EGFR in breast cancer specimens was examined by immunohistochemical analysis. RESULTS Ectopic expression of MICAL2 in MCF-7 cells augmented EGFR protein level, accompanied by the promotion of cell migration. Silencing MICAL2 in MDA-MB-231 cells destabilized EGFR and inhibited cell migration. In mechanism, the maintaining effect of MICAL2 on EGFR protein content was due to a delay in EGFR degradation. Expression of MICAL2 was also shown positively correlated with the activation of P38/HSP27 and P38/MMP9 signallings, which are the main downstream signalling cascades of EGF/EGFR involved in cell migration. Further analysis indicated that Rac1 activation contributed to the maintaining effect of MICAL2 on EGFR stability. In addition, analysis of breast cancer specimens revealed a positive correlation between MICAL2 and EGFR levels and an association between MICAL2 expression and worse prognosis. CONCLUSION MICAL2 is a major regulator of breast cancer cell migration, maintaining EGFR stability and subsequent EGFR/P38 signalling activation through inhibiting EGFR degradation in a Rac1-dependent manner.

Abstract
De novo serine synthesis plays important roles in normal mitochondrial function and cellular anti-oxidative capacity. It is reported to be mainly activated in glial cells of the central nervous system, but its role in retinal Müller glia remains unclear. In this study, we inhibited de novo serine synthesis using CBR-5884, a specific inhibitor of phosphoglycerate dehydrogenase (PHGDH, a rate limiting enzyme in de novo serine metabolism) in MIO-M1 cells (immortalized human Müller cells) and huPMCs (human primary Müller cells) under mild oxidative stress. Alamar blue and LDH (lactate dehydrogenase) assays showed significantly reduced metabolic activities and increased cellular damage of Müller cells, when exposed to CBR-5884 accompanied by mild oxidative stress; however, CBR-5884 alone had little effect. The increased cellular damage was partially reversed by supplementation with exogenous serine/glycine. HSP72 (an oxidative stress marker) and reactive oxygen species (ROS) levels were significantly increased; glutathione and NADPH/NADP+ levels were pronouncedly reduced under PHGDH inhibition accompanied by oxidative stress. JC-1 staining and Seahorse respiration experiments showed that inhibition of de novo serine synthesis in Müller cells can also increase mitochondrial stress and decrease mitochondrial ATP production. qPCR and Western blot demonstrated an increased expression of HSP60 (a key mitochondrial stress-related gene), and this was further validated in human retinal explants. Our study suggests that de novo serine synthesis is important for Müller cell survival, particularly when they are exposed to mild oxidative stress, possibly by maintaining mitochondrial function and generating glutathione and NADPH to counteract ROS.

Abstract
Objective: To evaluate the consistency in detection of T790M mutation of epidermal growth factor receptor gene (EGFR) in plasma and tumor samples of patients with lung adenocarcinoma. Methods: The tumor tissues or cytological specimens of 12 patients with operable lung adenocarcinoma(stage Ⅰ-ⅢA) and 100 patients with advanced stage ⅢB-Ⅳ lung adenocarcinoma were collected, among which 11 patients showed acquired resistance for gefitinib (11/100). In the same period, peripheral blood samples were collected from all patients and 50 healthy volunteers. Amplification refractory mutation system (ARMS) was used to detect EGFR mutations in tumor specimens. Next Generation Sequencing(NGS) based circulating single-molecule amplification and resequencing technology (cSMART)was performed to quantitatively detect the EGFR mutations in circulating tumor DNA (ctDNA) from plasma specimens. Results: The sensitivity, specificity and concordance rate of EGFR T790M mutation between plasma and tissue specimens from 100 advanced stage patients were 50.0%, 72.9% and 72.0%, respectively. For L858R mutation and exon 19 deletion mutations, the above mentioned sensitivity, specificity and concordance rate were 91.7%, 100.0%, and 98.0%, as well as 79.2%, 100.0% and 95.0%, respectively. The L858R mutation and exon 19 deletion mutations were not detected in plasma of 50 healthy volunteers, whereasT790M mutation(1.0±0.0 copies) was found in 7 individuals(7/50, 14.0%). Similarly, in 12 resectable patients, 4 (4/12, 33.3%) T790M mutations were found in plasma (1.2±0.2 copies), but no L858R mutation and 19 exon deletion mutations. In comparison, 28.0% of patients with advanced lung adenocarcinoma (28/100)had detectable T790M mutation in plasma with copy numbers (34.0±22.7 copies). Furthermore, the copy numbers of T790M were 268.2±119.9 in plasma of 5 cases with acquired gefitinib-resistance. Conclusions: In patients with advanced stages of lung adenocarcinoma, the detection of T790M mutation in plasma and tumor specimens is low. The T790M mutation also exists in the plasma of some healthy controls, suggesting that T790M mutation participates in EGFR signaling pathway and it might function in healthy population.

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
Setting: Three projects of the Fund for Innovative DOTS Expansion through Local Initiatives to Stop TB. Objectives: To assess unfavourable treatment outcomes (UTOs), including failure, died, loss to follow-up (LTFU), transferred out and unknown outcome, and to identify risk factors associated with UTOs. Design: This was a cross-sectional study using routine programme data. Results: Of 30 277 new smear-positive tuberculosis (TB) patients, 4261 (14.1%) had UTOs: 2048 (6.8%) LTFU, 1418 (4.7%) transferred out, 390 (1.3%) died, 340 (1.1%) failed and 65 (0.2%) had an unknown outcome. Risk factors for LTFU (including LTFU, transfer out and unknown outcome) were residing in Anhui, age > 55 years, service delay > 10 days, patient delay < 30 days, directly observed treatment (DOT) provided by a family member or others and unknown DOT provider. The outcome of 'died' was associated with residing in Shaanxi, age > 55 years, male sex, patient delay > 30 days and unknown DOT provider. 'Failed' was associated with having unlimited access to health services, patient delay of >30 days and unknown DOT provider. Conclusion: This study highlights the predominance of lost patients among UTOs. Patients with family members or other non-medical DOT providers or unknown DOT providers had a high risk of a UTO. There is an urgent need to address these service-related factors.

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.
