Objective To explore the possible role of vitamin D in the pathogenesis of IgA nephropathy (IgAN). Me-thods After the IgAN model was successfully induced at 12 weeks, the BALB/C mice were randomly divided into IgAN group (n=15) and IgAN+VitD group (n=15). The nephrosis mice were administrated with 100 μl/d propylene glycol or propyl-ene glycol+1,25(OH)2D, 3 ng/(100g?d), for 6 weeks. The control group was setted (n=15). The level of 24 hour urine protein was determined at week 0, 12 and 18. At week 18, the levels of serum 25(OH)D, ifbroblast growth factor 23 (FGF23) and galactose-deifcient IgA1 (Gd-IgA1) were detected. The mRNA and protein expressions of interleukin-21 (IL-21) in Peyer’s patches (PPs) were detected by lfuorescent quantitative reverse transcription-polymerase chain reaction and western blot respectively. The protein expression of Bcl-6 was detected by western blot. The percentages of Tfh cells/T lymphocytes, B220+IgM+/B lympho-cytes, B220+IgA+/B lymphocytes, B220-IgA+/B lymphocytes in PPs were determined by lfow cytometry. Results Compared with control group, the levels of 24 hour urine protein, FGF23 and Gd-IgA1 were increased, serum 25(OH)D was decreased, the mRNA and protein expressions of IL-21 and the protein level of Bcl-6 were increased, the percentages of Tfh cells/T lym-phocytes, B220+IgM+/B lymphocytes, B220+IgA+/B lymphocytes, B220-IgA+/B lymphocytes were elevated in IgAN group (P<0.05). These indicators were improved in IgAN+VitD group. Compared with the IgAN group, the differences were statisti-cally signiifcant (P<0.05), however compared with control group, some indicators showed no signiifcant differences (P>0.05). Conclusions 1,25(OH)2D may protect the microenvironment of PPs in IgAN through inhibiting the differentiation of Tfh cells and B cells and the generation of Gd-IgA1.

Objective To investigate the impact of pelvic muscle training (PFMT) on the quality of life (QOL) and incidence of postoperative complications in stress urinary incontinence (SUI) patients after tension-free vaginal tape surgery (TVT). In order to provide evidence for clinical nurses taking measures to promote rehabilitation of postoperative patients. Methods A total of 101 female SUI patients who underwent TVT surgery were included in this study. 50 patients in the trial group received pelvic muscle training guidance by one-to-one for 3months while 51 patients in the control group were instructed to the routine discharge guidance. All patients were asked to finish the Incontinence-specific Quality of Life questionnaire (I-QOL) at the day before surgery and 3 months after the surgery, respectively. And incidence of postoperative complications were evaluated at 3 months after the surgery. Results A total of 94 participants completed all questionnaires, including 48 patients of the trial group and 46 patients of the control group. The postoperative score of I-QOL in the trial group were higher than that of control group (94.32 vs. 90.34, Z=3.863, P<0.01). Further analysis found that avoidance and limiting behaviors domain score (90.63 vs.87.50, Z=3.227, P<0.01) and psychosocial impacts domain score (97.22 vs. 90.28, Z=4.186, P<0.01) in the trial group were higher than that of control group. The incidence of postoperative urgency urinary incontinence was significantly difference between the two groups (χ2=4.953,P=0.026), the proportion were 16.67% (8/48) in the trial group and 36.96% (17/46) in the control group, respectively. According to the results, the patients′overall quality of life of the trial group was better than that of control group after surgery. Conclusions Postoperative SUI patients′implementation of pelvic muscle training can significantly increase their quality of life and can decrease the incidence of urgency urinary incontinence.

Objective To investigate whether ultrasonic coupling agent (UCA)can produce shielding or antago-nistic effect on iodine disinfectant for preoperative skin disinfection.Methods Shielding or antagonistic effect of UCA on iodine disinfectant were detected by laboratory carrier immersion killing test and on-the-spot skin disinfec-tion test.Results Antagonistic effect:after the mixing of iodophor with UCA,the average killing rate of iodophor containing available iodine 2 500mg/L and 625 mg/L to Staphylococcus aureus decreased from 100.00% to 99.67%-99.78% and 96.85 % - 98.25 %,respectively;the average killing rate to Escherichia coli decreased from 100.00% to 99.71 %-99.82% and 95 .93 %-98.56%,respectively.Shielding effect:after smearing with UCA, the average killing rate of iodophor and iodine tincture + alcohol to Escherichia coli decreased from 100.00% to 30.76% and 100.00% to 94.48%,respectively;the average killing rate to Staphylococcus aureus decreased from 99.99% to 55 .55 % and 100.00% to 98.22%,respectively.On-the-spot skin disinfection test:the killing rate of io-dophor and iodine tincture +alcohol to natural bacteria on skin surface were both 99.99%,after skin was smeared with UCA,the killing rate decreased to 92.62% and 93 .57%,respectively.Conclusion UCA remained on the oper-ative field has shielding and antagonistic effect on iodine disinfectant.

Objective:To investigate whether thymic stromal lymphopoietin ( TSLP) participate in asthmatic airway remodeling partially by promoting myofibroblast accumulating in the lung. Methods:Twelve mice evenly were randomly divided into four groups:a saline group;an HDM-exposed group;an IgG isotype-treated group and an anti-TSLP-treated group. The supernatant of bronchoalveolar lavage fluid ( BALF) was used to analyze the levels of TSLP,IL-25 and IL-33 by ELISA. Fluorescence-labeled collagenⅠ( ColⅠ)/α-smooth muscle actin (α-SMA) -dual-positive myofibroblasts were examined by confocal microscopy. Results:Chronic allergen exposure induced obviously abnormal airway structural changes,which were inhibited by blocking TSLP. We detected a highly increased number of myofibroblasts in the sub-epithelial zone in mice from HDM-challenged group. However, TSLP neutralization significantly reduced myofibroblasts recruitment. Moreover,blocking TSLP not only decreased the level of TSLP,but also inhibited the expression levels of TGF-β1 and IL-33 in BAL fluid. Conclusion:The results suggest that orchestrating myofibroblasts recruiting into the lungs is one of the main pathogenesis that TSLP involves in airway remodeling in asthmatic mice.

Objective To evaluate the values of continuous subcutaneous insulin/rapid insulin analoguc infusion in desensitization for allergy to recombinant human insulin. Methods Two patients allergic to recombinant human insulin received desensitization therapy by continuous subcutaneous insulin lispro infusion. The diluted insulin lispro solution was pumped with initial basal rate of O. O1 U/h, and the basal rate and insulin lispro concentration increased gradually until the insulin dosage for clinical treatment was reached. After that, continuous subcutaneous insulin lispro infusion was replaced by regimen of insulin lispro subcutaneous injection plus oral hypoglycemic agents. Results Local wheals were not observed in both two patients during continuous subcutaneous insulin lispro infusion or during bolus subcutaneous injection of insulin lispro after desensitization. Conclusion The desensitization therapy by continuous subcutaneous insulin/rapid insulin analogue infusion can be applied for allergy to recombinant human insulin.

Objective:To understand the iodine content of edible salt in residents of Xinjiang Production and Construction Corps (referred to as Corps), and provide scientific evidence for prevention and treatment of iodine deficiency disorders.Methods:According to the requirements of the "National Iodine Deficiency Disorders Surveillance Program" form 2015 to 2019, in accordance with the principle of random sampling, one regiment from each of the five directions of east, west, south, north and center in the Corps was selected, and four companies were selected from each regiment. Edible salt samples from the homes of 15 residents in each company were collected, and salt iodine content was quantitatively tested and the test results were analyzed.Results:From 2015 to 2019, 21 028 household salt samples were collected, qualified iodized salt were 20 204, non-qualified iodized salt were 712, non-iodized salt were 112, iodized salt coverage rate was 99.47% (20 916/21 028), iodized salt qualified rate was 96.60% (20 204/20 916), qualified iodized salt consumption rate was 96.08% (20 204/21 028). The average salt iodine content was (27.72 ± 4.81) mg/kg. From 2015 to 2019, the iodized salt coverage rates in the whole Corps were all > 95%, and the iodized salt qualified rates and the qualified iodized salt consumption rate were all > 90%. Among the 14 divisions of the Corps, iodized salt coverage rates were all > 95%, except for the 12th and 14th divisions, where the iodized salt qualified rates and qualified iodized salt consumption rates were < 90%, all other divisions were > 90%.Conclusions:Iodized salt coverage rate, iodized salt qualified rate and qualified iodized salt consumption rate have all reached the national standard for eliminating iodine deficiency disorders from 2015 to 2019, however, non-iodized salt exists in some areas, and the qualified iodized salt consumption rate is low. We should strengthen monitoring of iodized salt in key areas and promote health education, consolidate and maintain achievements in eliminating iodine deficiency disorders.

Objective To assess the value of serum amyloid A (SAA) in patients with acute asthma attack. Methods Sixty-four asthmatic patients in acute phase and 20 healthy individuals were included. The asthmatic patients were divided into bacterial infection-induced group and non-bacterial infection-induced group. Lung function test and chest X-rays test were conducted And inflammatory cell counts , serum SAA and CRP levels were measured. SAA were compared among subgroups of asthmatic patients and healthy controls and the diagnostic value of SAA to distinguish bacterial infection-induced asthma was estimated. Results SAA of both asthma subgroups were significantly higher when compared with the healthy individuals, and it was higher in bacterial infection-induced group than that in non-bacterial infection-induced group. In terms of ROC curve , AUC was 0.966 for SAA to distinguish merging bacterium infection, and the cut-off value was 36.67mg/L with sensitivity of 92.3% and specificity of 88.2%. Conclusions SAA increases in patients during acute asthma attack, and particularlymore obviously in bacterial infection-induced patients. It may be used as a reliable biomarker to distinguish merging bacterium infection during acute asthma attack.
