Objective To study the association between serum free fatty acid (FFA) and ankylosing spondylitis (AS).Methods According to the classification criteria,a total of 90 newly diagnosed AS patients,223 healthy individuals and 82 patients with non-inflammatory diseases were divided into three groups,and biochemistry and immunology biomarks were measured in all individuals.One-Way analysis of variance (ANOVA) test was used to compare the difference between the three groups in the serum indexes,and Logistic regression analysis was used to identify AS risk factors associated with AS.Results There were no significant differences in gender,age,body mass index (BMI),white blood cells (WBC),high-level data link control (HDL-C),low-density lipoprotein control (LDL-C),lipoproteins [Lp (a)],alkaline phosphatase (ALP) and TG in the three groups,and our results showed that serum FFA was statistical different between the three groups (F=24.191,P＜0.01),the serum level of FFA in patients with AS was higher compared with patients with noninflammatory diseases and healthy controls [(0.48 ±0.18) mmol/L,(0.28 ±0.09) mmol/L,(0.29±0.16) mmol/L;t=-5.969,P＜0.01;t=5.106,P＜0.01].Seral IgA,IgG,IgM levels,ESR and CRP were statistically different between the three groups (F=14.870,P＜0.01;F=16.464,P＜0.01;F=4.124,P=0.018;F=97.002,P＜0.01;F=22.069,P＜0.01).Gender,age,BMI,serum IgA,IgM,ALP,HDL-C,LDL-C,Lp(a) and TG levels were not associated with AS by logistic regression analysis.However,serum IgG level,ESR and CRP were associated with AS [OR05％CI):1.659(1.032,2.660),P=0.037;OR05％CI):1.340(1.005,1.787),P=0.046;OR05％CI):1.820 (1.025,3.232),P=0.041],and there is an association between FFA and AS was observed in logistic regression analysis (OR=1.132,95％CI:1.014-1.421,P=0.033).Conclusion We suggest that incre-ased FFA is closely associated with AS,and may be an underlying risk factor for AS.

Objective:The effect of clotrimazole vaginal tablets combined with lactobacilli vaginal capsules on inflammatory response and oxidative stress in pregnant patients with candidal vaginitis.Methods:A prospective study of 126 patients with candidal vaginitis was randomly divided into control group and observation group, 63 cases in each group. The control group received clotrimazole vaginal tablets and the observation group received clotrimazole vaginal tablets combined with lactobacillus vaginal capsule treatment. The efficacy, inflammatory factor levels, oxidative stress and pregnancy outcomes of the two groups were observed.Results:The total clinical effective rate of the observation group was significantly higher than that of the control group (95.24% vs 80.95%, P<0.05). After treatment, the levels of tumor necrosis factor α, interleukin-6, and C-reactive protein inflammatory factors in the observation group were lower than those in the control group. The levels of superoxide dismutase and nitric oxide in the observation group were higher than those in the control group ( P<0.05), and the levels of malondialdehyde and plasma endothelin-1 were lower than those in the control group ( P<0.05). The incidence of premature delivery and premature rupture of membranes in the observation group was significantly lower than that in the control group ( P<0.05). Conclusions:Clotrimazole vaginal tablets combined with lactobacillus vaginal capsules for the treatment of pregnancy with candida vaginitis are effective and can reduce vaginal inflammation, improve oxidative stress, and reduce the occurrence of adverse pregnancy outcomes such as premature delivery and premature rupture of membranes.

OBJECTIVETo identify the differentially expressed proteins in the liver of Oncomelania snails induced by Eomecon chinanthe sanguinarine.

METHODSSanguinarine was extracted and purified from the dry powder of Eomecon chinanthe. Oncomelania snails were immersed in 5 mg/L sanguinarine (50 Oncomelania snails per 500 ml) or pure water for 36 h (25°C) and the livers were isolated from live snails. Total liver proteins were extracted and separated by two-dimensional gel electrophoresis. Electrophoretogram was analyzed by Image Master 2D 5.0 software. The differentially expressed proteins between sanguinarine group and pure water group were selected and analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and tandem mass spectrometry sequencing of tryptic peptides.

RESULTSIn terms of protein spots, 433 ± 14 and 385 ± 12 were observed in sanguinarine group and in water group respectively. The eleven identified differentially expressed proteins included tropomyosin, hypothetical protein XP_533132, actin 87E, keratin 6A, beta-tubulin, mitochondrial inner membrane protein isoform 4, keratin 2, allatostatin precursor, ENSANGP00000020184, actin-3 and ENSANGP00000013943. Among them, hypothetical protein XP_533132 and ENSANGP00000013943 were down-regulated and the other nine proteins were up-regulated in sanguinarine group.

CONCLUSIONSanguinarine could alter the expression of proteins in livers of Oncomelania snails.

OBJECTIVETo investigate the mechanism of tazarotene against active psoriasis vulgaris.

METHODSA randomized, controlled trial was conducted in 43 patients with active psoriasis vulgaris, who were divided into tazarotene and control groups. Promyelocytic leukemia (PML) mRNA in active psoriatic lesions before and 14 days after tazarotene treatment was detected by in situ hybridization.

RESULTSPML mRNA expression was detected not only in the basal layer (86.96%), but also in the suprabasal layers of the epidermis in the manner of focal expression (78.26%). After tazarotene treatment, virtually no PML mRNA expression could be detected in the psoriatic lesions (8.69% in the basal layer and 4.35% in the suprabasal layers). PML mRNA expression in the control group underwent no obvious changes during the observation.

CONCLUSIONSTazarotene may inhibit abnormal proliferation of keratinocytes through down-regulating PML gene expression in active psoriatic epidermis.

OBJECTIVETo establish WZS miniature swine model of beta-conglycinin (7 S) allergy for evaluating the potential allergenicity of genetically modified food.

METHODSTwelve 45-day-old WZS miniature swines from three litters were randomly divided into three groups (control group; 4% 7 S group and 8% 7 S group, n = 4), which were respectively gastric sensitized (day 0 - 10) and oral challenged (day 6 - 18, 31) to induce anaphylactic reactions. Clinical symptoms, skin prick reactions were recorded. At day 10, 19 and 32, serum IgG, IgE, histamine and cytokines levels were measured by ELISA.

RESULTSDiarrhea at different degrees were observed in 4% and 8% 7 S groups. The skin erythema reactions in grade "-", "+/-", "+", "++" of control group respectively were 2/4, 2/4, 0/4, 0/4, of 4% 7 S group were 0/4, 0/4, 2/4, 2/4 and of 8% 7 S group were 0/4, 0/4, 1/4, 3/4. The serum IgE and histamine levels of day 11, 19 and 32 were all significantly and positively correlated (Pearson coefficients = 1, P = 0.000). The serum IgG, IgE and histamine levels all reached the peak after 7 S groups were oral challenged at day 19.Compared with the control group, serum IgG (lg IgG: 2.95 +/- 0.31 vs 2.29 +/- 0.25, t = 3.19, P = 0.011), IgE (lg IgE: 2.45 +/- 0.30 vs 1.77 +/- 0.23, t = 3.31, P = 0.009) and histamine levels(lg histamine:2.13 +/- 0.30 vs 1.45 +/- 0.23, t = 3.34, P = 0.009) of 4% 7 S group at day 19 were all significantly higher, while the serum IFN-gamma content [(35.78 +/- 6.42) pg/ml vs (51.10 +/- 9.67) pg/ml, t = -2.33, P = 0.045] of 4%7 S group was significantly lower.

CONCLUSIONThe WZS miniature swine model orally induced by soybean beta-conglycinin is type I hypersensitivity mediated by IgE, which can be used to predict the potential allergenicity of genetically modified food.

Leigh syndrome is a genetically heterogeneous disease caused by defects in enzymes involved in aerobic energy metabolism and the Krebs', cycle. Mitonchondrial complex I deficiency is a main cause of Leigh syndrome. In this study, a Chinese child with Leigh syndrome caused by 13513G>A mutation was reported. The proband was the first child of his parents. The previously healthy boy presented with generalized epilepsy at 12 years of age. When he visited Peking University First Hospital at 13 years of age, he had subacute loss of vision in two eyes and temporal defect of visual field in the left eye. He walked with a spastic gait. His blood lactate and pyruvate levels were elevated. Muscle biopsy showed mild lipid accumulation in muscle fiber. An electrocardiogram showed incomplete right bundle branch block. Brain magnetic resonance imaging showed bilateral, symmetrical lesions in the basal ganglia, supporting the diagnosis of Leigh syndrome. 13513G>A mutation was identified by gene analysis in the patient, which led to mitochondrial respiratory chain complex I deficiency. Multivitamins and L-carnitine were administered. At present, the patient is 16 years old and has progressive deterioration with significant muscle weakness and body weight loss. He is absent from school. He has no obvious retardation in intelligence. 13513G>A mutation was first identified by gene analysis in Chinese population with Leigh syndrome. This may be helpful in genetic counseling.

OBJECTIVES: To assess the growth of preterm infants up to a corrected age of 24 months, and to understand the growth trend and pattern of preterm infants. METHODS: A preterm infant follow-up database was established based on the Internet Plus follow-up system. A total of 3 188 preterm infants who were born from April 2018 to April 2021 were enrolled. Their length, weight, and head circumference were recorded at birth and at the corrected ages of 1, 3, 6, 12, 18, and 24 months. The preterm infants were grouped by perinatal factors. The growth curves of these infants were plotted and compared with the International Fetal and Newborn Growth Consortium for the 21st Century (INTERGROWTH-21st) standard and World Health Organization (WHO) standard. RESULTS: The weight, length, and head circumference curves of each group of preterm infants grouped by various perinatal factors all rose rapidly within the corrected age of 6 months, but the growth rate slowed down after the corrected age of 6 months. Based on the actual age for the groups of preterm infants with different gestational ages (<28 weeks, 28-31 CONCLUSIONS The physical growth rate of preterm infants is faster within the corrected age of 6 months, and the growth rate slows down after the corrected age of 6 months. Preterm infants with a smaller gestational age need longer time to catch up in weight and head circumference. More attention should be paid to the physical growth of extremely preterm infants, extremely low birth weight infants, and small-for-gestational-age infants.

OBJECTIVE: To compare the assessment results of the Children Neuropsychological and Behavioral Scale-Revision 2016 (CNBS-R2016) between young children with autism spectrum disorder (ASD) and global developmental delay (GDD, without ASD) and to explore whether CNBS-R2016 could be helpful to early identification of ASD. METHODS: A total of 260 ASD and 371 GDD children aged 18-30 months were enrolled to finish the assessment of CNBS-R2016. The development quotients (DQs) of the five domains of CNBS-R2016 including gross motor, fine motor, adaptability, language and social behavior were compared between the two groups. The receiver operating characteristic (ROC) curve was used to evaluate the value of the autism-predicted domain in identifying ASD and GDD. RESULTS: The DQs of all the five domains in the ASD group were lower than those in the GDD group (P<0.05). The language DQ and total DQ of the ASD group had a negative correlation with the score of the autism-predicted domain (r=-0.566, -0.552 respectively, P<0.01). When the cut-off value of the autism-predicted domain was 10.5, the largest area under the ROC curve was 0.835, and the sensitivity and specificity for the diagnosis of ASD were 0.750 and 0.798 respectively. CONCLUSIONS The development of ASD children aged 18-30 months is worse than that of GDD children. CNBS-R2016 may be helpful to distinguish ASD from children with developmental delay.

This study reviews a case of mitochondrial respiratory chain complex I deficiency due to the 10191T>C mutation in mitochondrial ND3 gene. The previously healthy boy progressively presented with blepharoptosis, weakness, epilepsy and motor regression at age 6 years. Elevated blood lactate and pyruvate were observed. Brain magnetic resonance imaging showed symmetrical lesions in the basal ganglia. Leigh syndrome was thus confirmed. The protein from the mitochondria and genomic DNA of the boy and his parents was collected from peripheral blood leucocytes for the activity test for mitochondrial complex I to V and genetic analysis. The results showed the activity of complex I (33.1 nmol /min in 1 milligram mitochondrial protein) was lower than normal reference value (44.0±5.4 nmol /min in 1 milligram mitochondrial protein). The ratio of complex I to citrate synthase (19.8%) was also lower than normal reference value (48%±11%). The activities of complexes II to V were normal. 10191T>C mutation in ND3 gene of mitochondria was identified in the boy. 10191T>C mutation and complex I deficiency were not detected in his parents. At present, he is 16 years old, and of normal intelligence with spastic paralysis in both lower extremities after treatment. It is concluded that a Chinese boy with isolated complex I deficiency due to 10191T>C mutation in ND3 gene was firstly diagnosed by peripheral leukocytes mitochondrial respiratory chain enzyme assay and gene analysis. This study can provide clinical data for the nosogenesis of Leigh syndrome.

Menkes disease is a rare X-linked recessive disorder characterized by multi-systemic disorder of copper deficiency caused by ATP7A gene mutation. In this study, the clinical and laboratory features of three patients with Menkes disease were analyzed. Prenatal diagnosis had been performed for a fetus of a family. Three patients were admitted at the age of 8-9 months due to severe epilepsies and marked delayed psychomotor development. Significantly light complexion, pudgy cheeks and sparse fuzzy wooly hair were observed. On their cranial MR imaging, cortical atrophy, leukoencephalopathy, basal ganglia damage and tormesity of the intracranial vessels were found. Their plasma ceruloplasmin decreased to 70.2, 73.5 and 81 mg/L, significantly lower than normal range (210-530 mg/L). c.3914A>G (p. D1305G) was detected on ATP7A gene of case 1 and 2. A novel mutation, c.3265G>T (p.G1089X) was found in case 3. Both of them were firstly found in Chinese patients of Menkes disease. The mother of case 1 was tested at 20 weeks of pregnancy. Karyotype and ATP7A gene studies of the amniocytes were performed for the prenatal diagnosis of her fetus. Normal male karyotypes without c.3914A>G mutation on ATP7A gene was showed. Postnatal genetic analysis and normal development confirmed the prenatal diagnosis.
