ABSTRACT
Objective:To explore the changes of T follicular regulatory (T FR) cells/T follicular helper (T FH) cells and their related cytokines in peripheral blood of children with dust mite allergic asthma, and their clinical significance. Methods:A total of 25 children with acute dust mite allergic asthma (the asthma group) in Affiliated Hospital of Jiangnan University from January to December 2021 and 16 age- and sex-matched healthy volunteers (the healthy control group) at the same time were enrolled in the retrospective study.The percentages of peripheral T FR cells and T FH cells of the 2 groups were measured by flow cytometry.The plasma levels of cytokines[interleukin (IL)-10, IL-21] of the 2 groups were assessed by the flow cytometric microsphere-based array technology.The specific IgE (sIgE) levels of dust mites in 2 groups were detected by fluorescence enzyme immunoassay.The percentage of eosinophils in peripheral blood detected by blood cell analyzer.Data between groups were compared by t-test, and the correlation among indicators was analyzed by Spearman rank correlation analysis. Results:The asthma group had evident T FR cells/T FH cells immune imbalance.Compared with the healthy control group, the asthma group had a significantly lower T FR cells level[(0.11±0.03)% vs.(0.13±0.03)%], a significantly higher T FH cells level[(5.07±1.75)% vs.(3.80 ± 1.60)%], and a significantly lower ratio of T FR cells /T FH cells(0.02±0.01 vs.0.05±0.03) ( t=2.29, 2.30, 3.71; all P<0.05). Compared with the healthy control group, the asthma group had a significantly higher IL-21 level[(547.85±195.13) ng/L vs.(404.94±110.41) ng/L], and a significantly lower IL-10 level[(10.18±3.49) ng/L vs.(14.79±5.65) ng/L] ( t=2.60, 3.15; all P<0.05). The ratio of T FR cells/T FH cells in asthma group was negatively correlated with sIgE ( r=-0.444 2, P=0.026 1), but not related to the eosinophil percentage ( r=-0.135 2, P=0.519 3). Conclusions:Children with dust mite allergic asthma suffer from T FR cells/T FH cells subset imbalance.The imbalanced T FR cells, T FH cells and their related cytokines IL-10 and IL-21 may play a role in regulating the production of asthma sIgE.
ABSTRACT
Objective:To determine the effect of prolonging the interval of flushing on ports′ function and catheter related complications for cancer patients after completing chemotherapy.Methods:A prospective randomized controlled trial was conducted in 190 patients who undergoing ports-maintenance in outpatient clinical, the First Affiliated Hospital of Sun Yat-sen University, after they finished the chemotherapy from April 2017 to February 2018. According to the random number table, the patients were divided into 4-week group, 8-week group and 12-week group after completing chemotherapy, then returned to the hospital to maintain the port every 4 weeks, every 8 weeks and every 12 weeks, respectively. Then evaluated the function and complications of catheter among different groups.Results:After completion of chemotherapy, the rate of catheters′ patency of tumor patients in 12-week group was 98.5% (66/67), while that in 4-week group was 98.1% (53/54) and in 8-week group was 98.6% (68/69), there was no statistically significant difference on catheters′ patency among different groups ( χ 2=0.48, P>0.05). The rate of catheters′ asymptomatic thrombosis in 12-week group was 18.9% (10/53), which was not significantly different from that of 4-week group 27.0% (10/37) and 8-week group 14.0% (7/50) ( χ 2=2.33, P>0.05). Conclusions:Tumor patients maintaining port every 12 weeks after completion of chemotherapy can ensure the safety of patients using the port. It is favorable for application and promotion of port in cancer patients.
ABSTRACT
Objective To investigate the imaging features of peripheral schwannoma and analyze the relevant pathological basis to improve the preoperative diagnosis.Methods Fifty-one cases with schwannoma confirmed by pathological were analyzed retrospectively,and the CT and MRI findings were studied in correlation with pathological results.Results There were 24 cases in the neck,11 in the chest wall and 16 in the abdominal and pelvis.On the CT plain scan,12 cases showed slightly low and equal density,21 cases showed iso-density,5 cases showed low density.Most of the lesions showed mild to moderate homogenous enhancement and some lesions showed significantly heterogeneous enhancement on contrast-enhanced CT.On T1 WI,4 cases showed hypointense and isointense signal,and 1 case showed mixed signal.All cases showed hyperintense signal or mixed signal on T2 WI and heterogeneous marked enhancement on contrast-enhanced MRI.Conclusion Schwannomas in neck,chest wall,abdominal and pelvic have similar findings on CT and MRI. However,there are characteristic signs in different part.CT and MRI can accurately show the tumor shape,location,internal structure and relationship with adjacent structures,which has important value to diagnosis and differential diagnosis of peripheral schwannoma.
ABSTRACT
Objective To explore the function of soluble apoptosis inhibitive factor Fas (sFas) in pathogenesis of Graves ophthalmopathy (GO). Methods The subjects were enrolled in the Second Affiliated Hospital of Harbin Medical University from January 2014 to January 2017, and they were divided into three groups: GO accompanied with Graves disease (GD) group, GO without GD group and normal control group, with 30 patients in each group. Serum levels of sFas in three groups were investigated with enzyme-linked immunosorbent assay, and serum levels of freeing triiodothyronine (FT3), serum free thyroxine (FT4), thyrotrophin (TSH), thyroglobulin antibody (TGAb), thyroid peroxidase antibody (TPOAb) were measured by chemoluminescent technique, and compared. Results The serum level of sFas in GO accompanied with GD group was (0.76 ± 0.13)μg/L, which was higher than that in GO without GD group [(0.63 ± 0.08)μg/L] and normal control group [(0.52 ± 0.05)μg/L], and there was significant difference (P＜0.01). The serum level of sFas in GO without GD group and normal control group had significant difference (P＜0.05). The serum levels of FT3, FT4, TGAb, TPOAb in GO without GD group were lower than those in GO accompanied with GD group (P＜0.01).The serum level of TSH in GO without GD group was higher than that in GO accompanied with GD group (P＜0.01). The concentration of sFas were negatively correlated with FT3, FT4, TSH, TGAb and TPOAb (P > 0.05). Conclusions Abnormal serum concentration of sFas can be observed in patients with GD and GO which proves that sFas may play a role in the pathogenesis of GD and GO.
ABSTRACT
OBJECTIVE@#To observe the effects of a traditional Chinese medicine (TCM) capsule for replenishing qi, nourishing yin and activating blood on Notch/Hes1 signaling pathway in the renal tissue and vascular endothelial CD34 and CD144 expressions in a rat model of diabetic nephropathy.@*METHODS@#Rat models of early-stage diabetic nephropathy were established by left nephrectomy and high- fat and high- sugar feeding combined with intraperitoneal injection of STZ. The rats were randomized into model group, benazepril group, and high-, moderate-, and low-dose TCM capsule groups for corresponding treatments, with 6 normal rats as the control group. After 8 weeks of drug treatment, blood glucose and 24-h urinary albumin of the rats were measured, and the renal histopathology was observed with HE staining; Hes1 expression in the renal tissue was detected with immunohistochemical staining, and the renal expressions of CD34 and CD144 were detected using Western blotting.@*RESULTS@#Compared with the normal control group, the rat models of diabetic nephropathy showed obvious abnormalities in 24- h urinary albumin and expressions of Hes1, CD34 and CD144d. The TCM capsule at both the high and moderate doses significantly reduced 24-h urinary albumin in the rats; the renal expressions of Hes1 and CD34 was significantly reduced in all the dose groups, and the expression of CD144 was significantly reduced in the high- dose group. Compared with benazepril group, the TCM capsule obviously reduced CD34 expression at all the 3 doses and lowered CD144 expression at the low dose. Histopathologically, the rats in the model group showed glomerular hypertrophy, increased mesenteric matrix, thickening and widening of the mesenteric membrane, and nodular hyperplasia. These pathologies were obviously alleviated by treatment with the TCM capsule at the high and moderate doses.@*CONCLUSIONS@#The Traditional Chinese medicine (TCM) capsule for replenishing qi, nourishing yin and activating blood can reduce Hes1, CD34 and CD144 in kidney tissue of model rats, play a protective role on kidney function and delay the development of DN.

ABSTRACT
Objective To measure the prevalence and analyzed associated factors of medical adhesive-related skin injuries (MARSI) at PICC insertion site in patients with hematologic malignancies. Methods A cross- sectional observational study lasting two weeks was carried out in Department of Hematology. Skin assessment data and photographs of skin were collected during PICC maintenances by the same investigator. The related information was got out from the medical record. The observed skin injuries were classified by the dermatologist and PICC specialized nurse together. MARSI prevalence was calculated. The associated factors were analyzed statistically. Results All of the 153 patients with hematologic malignancies were included. The prevalence of total MARSI at PICC insertion site was 33.99%(52/153), including mechanical skin injury (22.87%,35/153), contact dermatitis (CD) ( 9.80%,15/153), moisture-associated skin damage (0.65%,1/153), folliculitis(0.65%,1/153), respectively. Multivariate analysis identified two independent risk factors for mechanical skin injury including age≥50 years old, P=0.016, odds ratio (OR)=5.919, 95%CI 1.389-25.220 and non-specialist nurses in PICC maintenance, P=0.013, OR=8.333,95%CI 1.566-44.360. History of skin allergies (P=0.000,OR=12.333,95%CI 3.669-41.454) and arsenic trioxide infusion through PICC(P=0.003,OR=4.565,95%CI 1.661-12.547) were associated with CD. Conclusions MARSI at PICC insertion site is a prevalent event in the patients with hematologic malignancies. Epidemiological data and independent risk factors are presented in our study, which provide a basis for future study in this area.
ABSTRACT

ABSTRACT
BACKGROUND:Apoptosis of islet cel s is closely related to the long-term hyperglycemia-and hyperlipemia-induced injuries. OBJECTIVE:To observe the effect of Shizidaiping formula on the apoptosis and insulin secretion in MIN6 cel s under the high glucose and lipid environment, and to explore the protective effect of Shizidaiping formula and the related apoptosis mechanism. METHODS:MIN6 cel s were divided into normal, model, melbine, low-, medium-and high-dose Shizidaiping formula groups. The cel activity was examined by cel counting kit-8, the insulin secretion was measured by ELISA, the rate of apoptosis was measured by Annexin V-FITC&PI and the expression levels of MEK1/2, ERK1/2 and p-ERK1/2 were examined by western blot assay. RESULTS AND CONCLUSION:Shizidaiping formula significantly improved MIN6 cel activity under high glucose and lipid condition (P<0.05), decreased early cel apoptosis, increased the level of insulin stimulated by low glucose in cel supernatant (P<0.05), and improved the expression levels of MEK1/2, ERK1/2 and p-ERK1/2 (P<0.05). These results suggest that Shizidaiping formula can protect islet cel s from hyperglycemia and hyperlipemia damage by improving the activity of MIN6 cel s, reducing the insulin secretion and inhibiting the apoptosis of pancreaticβcel s in MIN6 cel s.

ABSTRACT
Objective To investigate the characteristics and the risk factors of pulmonary function in patients with chronic obstructive pulmonary disease (COPD) for a 3 year follow-up.Methods Subjects diagnosed as COPD were followed up for 3 years in the Management Center of Chronic Respiratory Disease at XINQIAO Hospital from September 2009 to June 2012.This was a retrospective study.Parameters related to respiratory function mainly first second forced expiratory volume (FEV1),COPD assessment test (CAT),6 minutes walking distance (6MWD) and acute exacerbation were recorded during follow-up.Results Although the majority of patients were treated with drugs such as inhaled corticosteroid combined with longterm bronchial dilatation during the three years,FEV1 decreased progressively.The average annual decline of FEV1 was(31.80 ± 61.99) ml,translating into a mean annual decline of(3.74 ± 6.18) ％.However,there were significant differences in changes of FEV1.Approximately,FEV1 in 78.3％ (47/60) patients decreased,only 21.7％ (13/60) patients kept stable FEV1.There was a correlation between decrease of FEV1,FEV1 ％ predicted and the exacerbation (r =0.298,0.361,0.273;P ＜ 0.05).Logistic regression showed that the positive bronchodilator reversibility and the initial FEV1 were the independent factors associated with significant changes in FEV1 (respectively,OR =5.54,95％ CI 1.55-19.73;OR =8.28,95％ CI 1.42-48.32).Conclusion The changes of pulmonary function in patients with COPD are heterogeneous,although most patients are treated in a standard way.Nearly 80％ patients still represent deterioration of pulmonary function.Decline of FEV1 is closely related to the initial pulmonary function and bronchodilator reversibility.
ABSTRACT
ObjectiveTo study the clinical characteristics and laboratory ifndings ofMycoplasma pneumoniae (MP) and EBV infection in children and provide reference for clinical diagnosis and treatment.MethodsOne hundred and twenty two (122) hospitalized children with pathogen detection of MP and EBV double positive in hospitalized children with pneumonia from May 2013 to April 2014 (n=2213) were recruited as mixed infection group. In the mixed infection group, patients were further devided into high EBV mixed infection group if the EBV DNA copies were more than 1.0×104 copies/ml and the low EBV mixed infec-tion group when EBV DNA copies were less than 1.0×104 copies/ml. And another 45 hospitalized children with MP pneumonia were rectuited as control group. Clinical data and laboratory ifndings of all children were collected and analyzed.Results The mixed infection rate of MP and EBV was 5.51% (122/2213). As children getting older, the incidence of mixed infection was increased (χ2=84.08,P<0.001). And the mixed infection incidence in the lobar pneumonia group was signiifcantly higher than the bronchopneumonia group (χ2=37.44,P<0.001). The incidence of ALT and CK-MB elevated, lobar pneumonia, average fever days and hospitalization days in mixed infection with the high EBV copies group were signiifcantly higher than those in the low EBV copies group and the control group (bothP<0.05). The incidence of ALT and CK-MB elevated, average fever days and hos-pitalization days in mixed infection with the high EBV copies group were signiifcantly higher than those of the low EBV copies group and the control group (allP<0.05).ConclusionThe mixed infection of MP and EBV could aggravate the injury both in and out of the lung. Number of EBV copies plays an important role in the degree of injury both inside and outside the lung due to pneumonia with mixed infection of MP and EBV. When a patient with MP pneumonia complains with severe clinical symptoms and obvious injury outside the lung, EBV detection, especially quantitative detection of EBV DNA copies could be beneifcial for clinical diagnosis and treatment.
ABSTRACT
Objective To understand the implementation status and effect of prevention and control of malaria in Libo Coun?ty so as to provide the evidence for improving the malaria elimination working. Methods The data about malaria from the county CDC and county hospital were collected and 16 villages from 8 townships were randomly sampled and 10 villagers of each village were investigated. Other information about the prevention and control of malaria was also investigated. Results The inci?dence of malaria was decreasing annually from 5.75 per 10 000 in 2008 to zero in 2012. The malaria monitoring could be well conducted in the county and township levels. The infection source could be controlled in time. The utilization rate of anti?mosqui?to facilities in the residents was 93.25%and the awareness rate of knowledge about malaria prevention and control was 40.13%. Conclusions The implementation and effect of prevention and control of malaria are satisfactory in Libo County but the medi?um control is limited and the active protection consciousness of the residents is not strong. Therefore the task of malaria elimina?tion is still very arduous.
