Objective To detect the expressions of osteopontin (OPN) and inerleukin-18 in patients with bullous pemphigoid (BP),and to analyze their relationship with clinical and laboratory indices.Methods Enzyme linked immunosorbent assay (ELISA) was performed to quantify the serum levels of osteopontin (OPN) and inerleukin (IL)-18 in 30 patients with BP and 30 health controls.Results The serum level of OPN was statistically higher in the patients than in the healthy controls ((8.29 ± 2.76) vs.(3.88 ± 1.41 ) ng/ml,P ＜ 0.01 ),and was positively correlated with the severity of BP (r =0.658,P ＜ 0.01 ) and with some laboratory indices in the patients.Increased serum IL-18 level was observed in patients complicated by cardiovascular diseases compared with those without cardiovascular diseases ((37.49 ± 6.43) vs.(31.10 ± 5.40) pg/ml,P ＜ 0.01).Moreover,the BP patients with diabetes,tumor,hepatic and renal impairment displayed an enhanced level of serum OPN and IL-18 than those without (all P ＜ 0.05).Conclusions OPN may be positively correlated with the severity of BP,while IL-18 may be involved in the development of complications of BP.

Objective To explore the prevention and treatment of acute kidney injury (AKI) after gastrointestinal surgical procedures.Method We retrospectively analyzed the data of patients underwent gastrointestinal surgery in recent 2 years in the First Affiliated Hospital of Kunming Medical University and the First People's Hospital of Yunnan Province. Result The incidence of AK1 was 2.1%. Elderly patients with basic diseases had poorer prognosis than non-elderly patients. Conclusion In the patients after gastrointestinal Surgery, early rehydration, diuresis, ant-infection and preventive hemodialysis can achieve the goal of prevention and treatment of acute kidney injury in early stage.

To find a new preventive strategy for the infection of Schistosoma japonica, plasmid pIRES-Sj97-Sj14-Sj26 that contains fatty binding protein (Sj14), GST (Sj26) and paramyocin (Sj97) that are expressed on the membrane, was constructed. RT-PCR was used to detect the expression of Sj14 mRNA, Sj26 mRNA and Sj97 mRNA in the Hela cells, the indirect immunofluorescent test was employed for the detection of the expression of trans-membrane Sj26 after the plasmid was trans-fected into Hela cells. Fifty BALB/c mice were randomly divided into 5 groups and pIRES-Sj97-Sj14-Sj26 plasmid DNA, pIRES-Sj14-Sj26 plasmid DNA, plRES-Sj26 plasmid DNA,plRES blank vector and normal saline were respectively injected into the quadriceps muscles of thigh.Eight weeks after the immunization the mice were killed and significantly higher level of IgG was detected in the pIRES-Sj97-Sj14-Sj26 group as compared with the plRES blank vector, normal saline and pIRES-Sj26 groups (P<0.01) and the pIRES-Sj14-Sj26(P<0.05). Single splenocyte suspension was prepared to detected the level of IFN-γ by ELISA and the lymphocyte stimulating index (SI) by MTT SI was significantly higher of in the pIRES-Sj97-Sj14-Sj26 group than in other groups (P<0.01), while the IFN-γ, level was significantly higher the pIRES-Sj97-Sj14-Sj26 group than in pIRES blank vector and normal saline groups (P<0.01), but no significant differences were found when compared with pIRES-Sj14-Sj26 and pIRES-Sj26 groups. Flow cytometery showed that the percent-ages of CD4+ and CD8+ T cells were much higher in the pIRES-Sj97-Sj14-Sj26 group (P<0.01,P<0.05). It was concluded that pIRES-Sj97-Sj14-Sj26 vaccine may induce stronger immune response in BALB/c mice.

Objective? To explore effects of CoughAssist on sputum excretion efficacy among patients with intensive care unit-acquired weakness (ICU-AW). Methods? From January 2016 to December 2017, we selected 84 ICU-AW patients with mechanical ventilation of ICU in Hu'nan Provincial People's Hospital by convenience sampling. All of the patients were divided into control group and observation group with the random number table, 42 cases in each group. Two groups all received routine treatment and nursing. On this basis, observation group carried out CoughAssist therapy. We compared the sputum excretion effects, results of sputum smear/sputum culture, arterial blood gas indexes, respiratory mechanics indexes, the incidence of ventilator-associated pneumonia (VAP), time of mechanical ventilation, hospital days in ICU and the score of Medical Research Council (MRC) of patients between two groups. Results? There were no statistical difference in the volume of sputum excretion of patients in two groups before dividing groups (P＞0.05). One to three days after treatment, the volume of sputum excretion and number of effective sputum excretion patients in observation group were more than those in control group; the positive rate of sputum culture of patients in observation group was lower than that in control group; the differences were all statistical (P＜ 0.05). The partial pressure of oxygen (PaO2) of observation group was higher than that of control group; the partial pressure of carbon dioxide (PaCO2) of observation group was lower than that of control group; the differences were all statistical (P＜0.05). The pressure support/pressure control (PS/PC) and airway resistance of observation group were lower than those of control group;and the compliance and cough peak flow (PCF) were higher than those of control group with statistical differences (P＜ 0.01). The incidence of VAP, time of mechanical ventilation and hospital days in ICU of observation group were lower than those of control group (P＜0.05). There was no statistical difference in the scores of MRC between two groups (P＞0.05). Conclusions? The application of CoughAssist in ICU-AW patients with mechanical ventilation can improve the sputum excretion effects as well as respiratory function and shorten the time of mechanical ventilation and hospital days in ICU, and improve the clinical effects.

Objective:To investigate the effects of mixed probiotics on food allergy and the underlying mechanism.Methods:BALB/c mice on the 15 th day of pregnancy were randomly (random number table method) classified into the control group, food allergy model group and mixed probiotics group.Mice in the food allergy model and mixed pro-biotics group were subjected to ovalbumin (OVA) sensitization after birth, and those in the mixed probiotics group were then given probiotic solution by gavage from day 21 to day 35.Mice in control group were similarly given 9 g/L saline.Twenty-four hours after the last OVA sensitization, intestinal histopathological sections were prepared to observe intestinal pathological changes.Blood smears were prepared to detect eosinophil count.In addition, serum samples were collected to measure cytokine levels and OVA specific antibodies.The number of dendritic cells (DCs) and regulatory T cells (Tregs) in mouse mesenteric lymph nodes was calculated.Differences among 3 groups were compared by the One- Way ANOVA or Kruskal- Wallis H test. Results:Compared with those of food allergy model group, diarrhea score, the ratio of eosinophils and serum levels of interleukin(IL)-4, IL-5, IL-13, mast cell protease 1 (MCPT-1), and OVA specific antibodies IgE and IgG were significantly lower in mixed probiotics group[(2.00±0.71) points vs.(3.22±0.97) points, (2.28±1.61)% vs.(10.99±2.26)%, (413.68±22.81) ng/L vs.(708.78±27.66) ng/L, (36.64±3.74) ng/L vs.(46.05±4.95) ng/L, (201.37±65.61) ng/L vs.(495.22±96.66) ng/L, (31 924.15±1 177.77) ng/L vs.(36 175.77±618.29) ng/L, (9.10±8.08) ng/L vs.(19.69±0.84) ng/L, (30.50±8.81) ng/L vs.(190.32±6.40) ng/L], while IL-10 level was significantly higher[(164.12±3.88) ng/L vs.(123.90±7.31) ng/L] ( t=3.37, 8.72, 16.07, 3.90, 7.40, 7.95, 3.91, 44.00 and 7.76, respectively, all P<0.01). Compared with those of food allergy model group, programmed cell death ligand 1 (PD-L1) level on the surface of CD 103+ DCs and CD 103+ CD 80-CD 40-DCs, the proportion of Tregs in CD4 + T cells, and the level of programmed cell death 1 (PD-1) on the surface of Tregs were significantly higher in mixed probiotics group[(75.59±0.45)% vs.(45.60±4.73)%, (67.56±1.87)% vs.(37.12±6.07)%, (8.24±0.69)% vs.(6.20±0.66)%, (11.25±3.12)% vs.(4.08±2.33)%]( t=7.88, 4.48, 3.63 and 3.71, all P<0.01). Conclusions:Mixed probiotics can alleviate the symptoms of food allergy and inflammatory response of young rats through mediating Tregs via the PD-1/PD-L1 pathway.

Objective:To explore the early-stage language characteristics of children with autism spectrum disorder (ASD), global developmental delay (GDD), and developmental language disorder (DLD) at the same deve-lopmental level, thus providing references for their diagnosis.Methods:Clinical data of 719 children, involving 382 ASD patients, 198 DLD patients and 139 GDD patients presented to the Children′s Hospital Affiliated to Chongqing Medical University from January 2018 to January 2020 were retrospectively analyzed. Chi- square test was used to compare the developmental distribution of 3 groups.Variance analysis was used to analyze difference of developmental levels among 3 groups.Correlation analysis was used to analyse relationship between language and nonverbal abilities.At the same developmental, student′s t test was used to compare ASD with GDD, ASD with DLD in language ability, and difference of expression with receptive and visual related language. Results:The nonverbal developmental levels of ASD, GDD, DLD children were significantly different ( χ2=414.64, P<0.01). Language abilities were correlated with non-verbal developmental levels( r=0.60, P<0.05). The receptive and visual-related language abilities of ASD children with abnormal developmental level were more delayed compared with that of expressive language ( t=6.97, 3.58, 13.29, 6.85, 9.09, 7.27, all P<0.01). Expressive language of DLD children with normal developmental level was worse than visual-related and receptive language( t=-2.21, -3.61, all P<0.05). In GDD children with mild delayed development, receptive language was worse than expressive and visual-related language ( t=4.12, -4.24, all P<0.01), GDD children with moderate and worse development had worse visual-related and receptive language than the expression ( t=2.46, 2.68, all P<0.01). No significant differences in the expressive, receptive and visual-related language were detected in ASD and DLD children with normal development level and those with delayed development level (all P>0.05). Receptive and visual related language of ASD children with marginal delayed development level were significantly worse than those of DLD children ( t=-4.64, -4.60, all P<0.01), whereas no significant diffe-rence in the expression was detected ( P>0.05). In ASD children with mild delayed developmental level, the receptive and visual-related language were worse than those of GDD children( t=-4.11, -4.68, all P<0.01), whereas no significant difference in the expression was detected ( P>0.05). Conclusions:In early childhood, ASD children with abnormal developmental levels present severe delay in receptive and visual related language.DLD children with normal development have an obvious delay in expressive language.The language abilities of GDD children are globally delayed, especially the receptive language.In the marginal and mild delayed developmental level, ASD is featured by obvious delay of receptive and visual-related language.In normal and worse delayed development levels, the development of language in ASD, DLD and GDD children is similar.

Objective:To investigate the physical indices and growth status of preterm children aged 0 to 4 years with different birth weight.Methods:Following the real world research approach, the current study retrospectively collected e-chart information of 8 496 preterm children from the child health care system of the Children′s Hospital of Chongqing Medical University from December 2010 to December 2017, with 203 123 full-term children followed up during the same period as controls. Premature children were divided into normal birth weight (NBW) group, low birth weight (LBW) group, and very low birth weight (VLBW) group based on their birth weights. The weight and length development within 48 months of age of preterm boys and girls in each group were measured and recorded to establish a numerical table and analyze the growth levels, growth rate, and proportionality. The t-test or chi-square test was used for between-group comparison. Results:Of the 8 496 preterm children, 4 839 were girls and 3 657 boys, including 525 in the VLBW group, with an average birth weight of (1.28±0.14) kg, 3 862 in the LBW group, with an average birth weight of (2.07±0.28) kg, and 4 109 in the NBW group, with an average birth weight of (2.86±0.35) kg. The weight at the actual age of 2-<3 months ((5.61±0.96) vs. (5.64±0.78) kg in boys, (5.11±0.67) vs. (5.18±0.71) kg in girls) and the length at the actual age of 8-<10 months ((70.3±2.4) vs. (70.6±2.4) cm in boys, (68.9±2.2) vs. (68.9±2.4) cm in girls) in the NBW group reached the average weight and length of full-term children. The difference of physical growth before 24 months of age between LBW and control group decreased as children age, with that of LBW group approaches the average of full-term children after 24 months of age, with a weight difference of 0.64-0.95 kg and height difference of 1.3-1.7 cm. The weight and height of the VLBW group were lower than those of full-term infants (2.80-2.86 kg and 3.3-4.3 cm, respectively) at 48 months of age. During 2-12 months of age, the corresponding values of the VLBW group were higher than that of the LBW and NBW groups by 0.35 kg and 0.71 kg, respectively. However, the corresponding values of the VLBW group were lower than that of the LBW and NBW groups(0.64 kg and 0.76 kg at 0-2 months of age, 1.04 kg and 1.49 kg at 12-48 months of age, respectively). The rates of delayed development, underweight, and emaciation were the highest in the VLBW group (all P<0.01), while the rates of overweight and obesity were the highest in the NBW group, with that of the VLBW group being lower than LBW group ( P<0.01) at the age of 24-<36 months. Conclusions:Prior to 4 years of age, the time for preterm children to reach the average physical indices of full-term children differ by birth weights, hence warranting further examination of the corrected gestational age for preterm children. Normal birth weight preterm children present with the highest incidence of overweight and obesity and very low birth weight preterm children present with the highest incidence of growth disorders, marking both groups at high risks of malnutrition.

Objective:To explore the language characteristics of children with autism spectrum disorder (ASD) at different developmental levels.Methods:The clinical data of 103 children with ASD who attended the Children′s Hospital of Chongqing Medical University from January 2018 to December 2020 was analyzed retrospectively. They were divided into typical development and abnormal development (including mild and moderate or severe) groups based on developmental diagnostic scale results, and also devided into 2-3, 4-6, and 7-8 years of age groups based on age. The language characteristics of children with ASD at different developmental levels and different ages were compared by Pearson′s chi-square or Fisher′s exact probabilty test, t test, analysis of variance, or Kruskal-Wallis H test. The relationship between language ability and core symptoms of ASD was analyzed by Pearson correlation test. Results:Among 103 children with ASD, 86 were males and 17 were females, with an age of (5.5±1.5) years. A total of 61 children were charactered as typical development and 42 as abnormal (32 mild and 10 moderate or severe). There were no significant differences in developmental scale, overall language, receptive, expressive, syntax, and semantics scores among the three different age groups (all P>0.05). The detection rate of abnormal language ability in the typical development group was significantly lower than that in the abnormal development group (49.2% (30/61) vs. 100.0% (42/42), P<0.01). Receptive, expressive, semantics, and syntax scores of the typical development groups were significantly higher than those of the mildly and moderately or severely abnormal group (89±13 vs. 76±11 vs.71±8, F=18.61, P<0.01; 80±12 vs. 66±8 vs. 58±7, F=29.69, P<0.01; 92±14 vs.78±14 vs. 71±11, F=17.26, P<0.01; 83±10 vs. 71±8 vs. 64±5, F=29.35, P<0.01). Within the abnormal development group, there were no significant correlations between language ability and the core symptoms of ASD ( r=-0.02-0.58, all P>0.05). Within the typical development group, there were no significant correlations between language ability and social interaction, repetitive stereotypes, and limited interests ( r=0--0.22, all P>0.05). However, overall language, receptive, semantics, and expressive language abilities were negatively correlated with communication ( r=-0.28--0.36, all P<0.05), and there was no significant correlation between syntax and communication ( r=-0.24, P>0.05) in typical developmental group. Conclusions:The majority of children with ASD manifest language development disorders, mainly in the aspects of expressive and syntax language. Children with ASD with more delayed developmental level have more severe language disorder. About half children with ASD with normal development have language development disorders. The language ability of children with ASD is minimally correlated with ASD core symptoms.
