ObjectiveTo explore the effect of Buzhong Yiqitang on the immune imbalance of helper T cell 17 （Th17）/regulatory T cell （Treg） and Notch1 signaling pathway in mice with autoimmune thyroiditis （AIT）. MethodA total of 60 8-week-old NOD.H-2^h4 mice were randomly divided into the normal group， model group， western medicine group （selenium yeast tablet， 32.5 mg·kg^-1）， and low-dose （4.78 g·kg^-1·d^-1）， middle-dose （9.56 g·kg^-1·d^-1）， and high-dose （19 g·kg^-1·d^-1） Buzhong Yiqitang groups， with 10 mice in each group. The normal group was fed with distilled water， and the other groups were fed with water containing 0.05% sodium iodide for eight weeks. After the animal model of AIT was formed spontaneously， the mice were killed under anesthesia after intragastric administration for eight weeks. Serum anti-thyroglobulin antibodies （TGAb）， thyroid-stimulating hormone （TSH）， free triiodothyronine （FT3）， and free thyroid hormone （FT4） were detected by enzyme-linked immunosorbent assay （ELISA）， and thyroid tissue changes were observed by hematoxylin-eosin （HE） staining. The mRNA and protein expressions of retinoid-related orphan receptor-γt （RORγt）， interleukin （IL）-17， forkhead box P3 （FoxP3）， IL-10， Notch1， and hair division-related enhancer 1 （Hes1） in thyroid tissue were detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. ResultCompared with the normal group， the thyroid structure of the model group was severely damaged， and lymphocytes were infiltrated obviously. The levels of serum TGAb， FT3， and FT4 contents were significantly increased， and TSH content was significantly decreased （P<0.01）. The mRNA and protein expression levels of RORγt， IL-17， Notch1， and Hes1 were significantly increased， while those of FoxP3 and IL10 were significantly decreased in the model group （P<0.01）. Compared with the model group， thyroid structural damage and lymphocyte infiltration were improved in the treatment groups， and serum TGAb， FT3， and FT4 contents were significantly decreased. TSH content was increased， and mRNA and protein expression levels of RORγt， IL-17， Notch1， and Hes1 were decreased. mRNA and protein expression levels of FoxP3 and IL-10 were increased to different degrees （P<0.05， P<0.01）， and the middle-dose Buzhong Yiqitang group had the most significant intervention effect. ConclusionBuzhong Yiqitang can alleviate the thyroid structural damage in AIT mice， and its mechanism may be related to improving the abnormal differentiation of Th17/Treg immune cells and inhibiting the activation of the Notch1 signaling pathway.

Objective To explore the clinical efficacy and prognostic factors of YL-1 type hard channel trepanation and drainage combined with stereotactic treatment for hypertensive intracerebral hemorrhage.Methods A retrospective study was conducted on 110 patients with hypertensive intracerebral hemorrhage at the Cerebrovascular Disease Center of the First People's Hospital of Suzhou from August 2019 to October 2022.The observation group(55 cases)received YL-1 type hard channel drilling and drainage combined with stereotactic treatment,while the control group(55 cases)received simple YL-1 type hard channel drilling and drainage.The perioperative indicators,neurological damage,and prognosis of the two groups of patients were compared;Using multiple Logistic regression analysis to identify the prognostic factors affecting patients.Results The perioperative indicators,neurological damage,and prognosis of the observation group were better than those of the control group(P＜0.05);The admission NIHSS score(OR=2.504,P＜0.05),simple minimally invasive drilling and drainage(OR=1.881,P＜0.05),disease duration＞24 hours(OR=2.782,P＜0.001),and ventricular rupture(OR=2.252,P＜0.05)are risk factors for poor prognosis in patients.Conclusion The prolongation of the patient's disease course,ventricular rupture,and severe neurological damage are associated with poor prognosis.Combining stereotactic minimally invasive surgery has a positive significance for improving the prognosis of patients with cerebral hemorrhage.

OBJECTIVE To investigate the effects of total glucosides of paeony （TGP） on enhancing efficacy and reducing toxicity of Tripterygium wilfordii polyglycoside （TWP） in the treatment of eczema. METHODS Totally 50 SD male rats were collected to establish eczema model by sensitizing with 2，4-dinitrofluorobenzene-acetone olive oil solution （volume ratio was 4∶1） on the abdominal area and provoking on the back and ear. Model rats were randomly divided into model group， loratadine group （0.9 mg/kg）， TWP group （9.45 mg/kg）， TGP group （162 mg/kg） and compatibility group （TWP 9.45 mg/kg+TGP 162 mg/kg）， with 10 rats in each group. Other 10 rats were collected to set as normal group. Three days after the first sensitization， administration groups were given relevant medicine intragastrically， and normal group and model group were given constant volume of 0.1% CMC-Na solution intragastrically， once a day， for consecutive 21 d. Twenty-four hours later after the final administration， the general condition of rats in each group was observed， and the eczema area and severity index （EASI） were scored； ear swelling degree of rats was measured， and the skinhistomorphology observation and pathological score were performed； protein expressions of p38 mitogen-activated 13938427612@126.com protein kinase （p38 MAPK）， phosphorylated p38 MAPK （p- MAPK） and phosphorylation level of p38 MAPK in rat skin tissue were detected； the levels of inflammatory indexes （interleukin-4， interferon- γ）， liver and kidney function indexes [glutamic-pyruvic transaminase （GPT）， glutamic-oxaloacetic transaminase （GOT）， serum creatinine （SCr） and blood urea nitrogen （BUN）] and oxidant stress indexes [total superoxide dismutase （T-SOD） and malondialdehyde （MDA）] were measured. RESULTS Compared with normal group， EASI score， ear swelling degree， pathological score， protein expressions of p38 MAPK and p-p38 MAPK， phosphorylation level of p38 MAPK， the levels of inflammatory indexes and BUN were all increased significantly in model group （P＜0.05）. Compared with model group， EASI scores， ear swelling degree， pathological scores， protein expressions of p38 MAPK and p-p38 MAPK， phosphorylation levels of p38 MAPK and levels of inflammatory indexes were all improved significantly in administration groups （P＜0.05）. The levels of GPT， GOT， SCr and BUN were increased significantly in TWP group， while the serum levels of GOT and SCr in TGP group and serum level of SCr in loratadine group were all decreased significantly （P＜0.05）. The levels of T-SOD in liver and kidney tissue were all decreased significantly in TWP group and compatibility group， while the levels of MDA were increased significantly （P＜0.05）. The compatibility group showed more obvious effect in improving the ear swelling degree， pathological score， p38 MAPK expression and its phosphorylation level and levels of inflammatory indexes， and could reverse the abnormality of liver and kidney indexes caused by TWP （P＜0.05）. CONCLUSIONS The combination of TGP and TWP has the effects of anti-inflammatory， synergistic and hepatorenal detoxification in eczema model rats. Its mechanism may be associated with down-regulating the expression of serum proinflammatory indexes and inhibiting the activation of p38 MAPK pathway.

Objective:Extracorporeal carbon dioxide removal(ECCO 2R) is a technique that aims to decarboxylate the blood and thus to correct hypercapnia and respiratory acidosis in acute respiratory failure, but is rarely used in children.We successfully completed the ECCO 2R treatment for a pediatric case with adenovirus pneumonia, severe acute respiratory distress syndrome(ARDS) and hypercapnia in PICU, which provided clinical references for the use of ECCO 2R in acute respiratory failure for children. Methods:A patient with adenovirus pneumonia and severe ARDS was successfully treated with ECCO 2R-continuous renal replacement therapy(CRRT)combined system after weaning from extracorporeal membrane oxygenation(ECMO). We reported the treatment process, ECCO 2R treatment effect and side effects, so as to provide clinical reference for ECCO 2R treatment of children with ARDS. Results:One-year and four-month-old boy was treated with mechanical ventilation and venous-arterial ECMO due to adenovirus pneumonia and severe ARDS.After ECMO treatment for 25 days, he developed severe hypercapnia after weaning from ECMO.ECCO 2R was initiated.The pH value increased by 11.2%(from 7.222 to 7.303) 1 hour after ECCO 2R treatment, partial pressure of blood carbon dioxide(PCO 2)decreased by 29.1%(from 72.6 mmHg to 51.5 mmHg, 1 mmHg=0.133 kPa) and the average airway pressure of high-frequency ventilation decreased by 5 cmH 2O(from 20 cmH 2O to 15 cmH 2O, 1 cmH 2O=0.098 kPa) after 6 hours of ECCO 2R.The CO 2 removal rate of ECCO 2R system was 29.1 mL/min.It was stopped because of ECCO 2R-membrane clotting after 72 h. There was no increase of PCO 2.Extubation was successfully after undergoing invasive mechanical ventilation for 39 days and with noninvasive ventilation for 5 days.The boy was hospitalized in PICU for 54 days, improved and discharged from the hospital.Followed up for 2 years after discharge, the growth and development were good, but the strenuous exercise endurance was still poor. Conclusion:ECCO 2R is effective in improving gas exchange, reducing PCO 2 and lowering ventilator pressure in children with ARDS and hypercapnia, which allow more protective ventilation.ECCO 2R provide transitional treatment for ECMO weaning and provide meaningful clinical reference for the use of ECCO 2R as part of respiratory support in children with respiratory failure.

【Objective】 To study the annual financial expenditure in blood stations with different scales, and to establish the regression equation between blood collection units and total expenditure. 【Methods】 The annual total expenditure, the per capita cost of serving population, as well as the collection units of whole blood and apheresis platelet of 24 blood stations were collected. The financial expenditure required for collecting 10 000U blood was calculated.The statistical analysis was carried out with SPSS statistical software. 【Results】 From 2017 to 2020, the total annual financial expenditure of 24 blood stations showed an upward trend. The total expenditure among blood stations was different. The per capita cost of servicing population in the areas where the 24 blood stations were located had been increasing year by year. The 24 blood stations were divided into two grades according to the blood collection volume as 50 000 U, and the relationship equation between the blood collection volume and the annual total expenditure had been established. After testing, each equation was effective(P<0.05); There was no difference in the financial expenditure required for collecting 10 000U blood among blood stations with different scales. 【Conclusion】 From 2017 to 2020, the blood stations with an annual collection volume more than 50 000 U demonstrated a higher financial expenditure and the per capita cost of serving population than those <50 000 U. The blood collection volume of blood stations is significantly correlated with the annual total expenditure and the per capita cost of serving population.

Objective: To explore the association between dietary pattern which benefit for normal kidney function and the risk of cognitive decline or impairment in the elderly. Methods: In 2015, subjects aged 60 and over from four counties in the Nutrition and Chronic Disease Family Cohort project, were followed up in 2017. Cognitive function was repeatedly assessed, using the Mini Mental State Evaluation (MMSE) scale. Dietary pattern that benefit for normal kidney function was extracted, using the reduced rank regression method and followed by logistic regression models to explore the associations between scores that showing the kidney function on dietary patterns and the risk of cognitive deterioration and impairment in two years among those who were with normal cognition in 2015. Results: Dietary pattern that benefit for normal kidney function, was characterized by high consumption of cereal, vegetables, legume and fruits but with less meat and soy products. Comparing with the group with lowest score quartile on this dietary pattern, the risk of cognitive deterioration in the highest quartile group was significantly low (P<0.01) in two years, with an odds ratio as 0.57 (95%CI: 0.37-0.85). Linear trend was also obviously visible (P=0.007) in this group. The ones at the highest quartile group among the normal cognition ones in 2015, the risk of cognitive impairment also significantly reduced (P<0.05) in two years time, with an odds ratio as 0.52 (95%CI: 0.29-0.93). Also, linear trend could obviously be seen (P=0.01). Conclusion Dietary pattern that benefit for normal kidney function was both inversely associated with cognitive deterioration and impairment, in two years.

Objective: To assess the relationship between body mass index (BMI) and mortality in adults of Shanxi, China. Methods: Baseline data were from the '2002 China Nutrition and Health Survey’ in Shanxi province. All the death-related investigation and follow-up visits were carried out from December 2015 to March 2016. The follow-up program covered 5 360 people from all the 7 007 participants aged 18 years and over that having complete core information, with a rate as 76.5%. Participants of this study were divided into eight groups, according to the appearance of BMI. Taking the group with the lowest mortality density as the reference group, Cox regression model was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) of deaths by the whole population, gender and age groups (≥60 years, <60 years). Results were then adjusted by age, gender, smoking, alcohol use and education level from the baseline survey. Sensitivity analysis was also conducted. Results: Results from the study showed that among the total number of 67 129 person- years from the average period of 12.5 years, there were 615 deaths occurred, with the mortality density as 916 per 100 000 person-years. Taking the BMI range of 26.0-27.9 kg/m² as the reference, the aHRs of death increased to 1.90 (95%CI: 1.26-2.86), 1.68 (95%CI: 1.15-2.45), 1.49 (95%CI: 1.08-2.06) and 1.72 (95%CI: 1.07-2.76) after the multivariate adjustment, in these four groups (BMI<18.5, 18.5-19.9, 22.0-23.9 and ≥30.0 kg/m²), respectively. Low body weight (BMI<18.5 kg/m²) was associated with higher risks of death in the elderly of ≥60 years, with the aHR of death as 1.94 (95%CI: 1.20-3.15). Conclusions When BMI appeared as ≤19.9 kg/m², 22.0-23.9 kg/m² and ≥30.0 kg/m², the risks of death would increase. In addition to programs that focusing on obesity, special attention should be paid to the high risk of mortality which was caused by low-weight and malnutrition in the elderly.
