Bronchial asthma(asthma for short) is a chronic inflammatory disease of the lung,which is involved with various cells and cytokines.Now,the related genes of asthma is not well-known yet.But research shows that there are related genes to airway hyperreactivity,IgE regulation and atopic reaction.These genes play an important role in asthma.In recent years,it is recognized that STAT family plays an important role in inflammatory and immunological diseases.In this article the role of STAT family played in asthma pathogenesis will be reviewed.

BACKGROUND:In recent decades, total knee arthroplasty is widely used in the treatment of terminal knee joint diseases, such as osteoarthritis, rheumatoid arthritis, traumatic arthritis and other bone diseases. The methods of osteotomy, soft tissue balance and prosthesis rotation positioning have always been debated and discussed in total knee arthroplasty. OBJECTIVE:To explore the repair effect of total knee arthroplasty for terminal knee disease. METHODS:Total knee arthroplasty was performed for treating terminal knee disease in 31 cases (31 knees), including 26 cases of osteoarthritis (26 knees) and 5 cases of rheumatoid arthritis (5 knees). Al cases accompanied flexion contracture deformity to different degrees. The maximum angle of flexion deformity was < 25°. Al patients were scored by hospital for special surgery knee score before and after replacement. Al 31 knees were treated with fixed platform posterior-stabilized prostheses. RESULTS AND CONCLUSION:No complications, such as early infection and prosthesis dislocation, were found after surgery. Joint pain apparently lessened, flexion and varus deformity obviously improved after replacement. Postoperative X-ray films showed good prosthesis position and low limb alignment. Al cases were folowed up for 6-12 months. The hospital for special surgery knee score improved significantly from preoperatively 46.4±5.3 to postoperatively 84.6±10.5 after 6 months of folow-up. Excelent and good rate was 84%. Results indicate that total knee arthroplasty for treating terminal knee disease has a good clinical effect. However, the operation is complex and precise technique is required.

Objective:To investigate the characteristics of blood glucose fluctuation and risk factors in type 2 diabetic patients with asymptomatic hypoglycemia.Methods:From September 2018 to July 2021, 342 patients with type 2 diabete mellitus who were hospitalized in the Department of Endocrinology of Hefei Hospital Affilitated to Anhui Medical University were enrolled for a retrospective study. The mean amplitude of glycemic excursions(MAGE), coefficient of variation (CV), 24 hour mean blood glucose level (MG), and time in range (TIR) were obtained by continuous glucose monitoring (CGM). According to the results of CGM and whether the patients have hypoglycemia symptoms, they were divided into three groups: no hypoglycemia group, symptomatic hypoglycemia group, and asymptomatic hypoglycemia group. The differences in blood glucose fluctuations were compared among the three groups. Multivariate logistic regression analysis was used to evaluate the risk factors in type 2 diabete mellitus patients with asymptomatic hypoglycemia. The predictive value of MAGE for asymptomatic hypoglycemia was analyzed by receiver operating characteristic (ROC) curve.Results:Compared with the non-hypoglycemia group, the TIR in asymptomatic hypoglycemia group was higher ( Z=-2.042, P=0.041). The asymptomatic hypoglycemia group had lower MG, higher MAGE and CV compared with the other two groups(all P<0.05). Multivariate logistic regression analysis showed that urinary albumin/creatinine ratio (UACR), MAGE, and CV were the risk factors for asymptomatic hypoglycemia, while MG was the protective factor. After adjustment for other risk factors, MAGE was still associated with asymptomatic hypoglycemia ( OR=1.111, 95% CI 0.999-1.235, P=0.049). The sensitivity and specificity of MAGE in predicting asymptomatic hypoglycemia were 0.769 and 0.776, respectively. Conclusions:Patients with asymptomatic hypoglycemia present with larger TIR and MAGE. MAGE, UACR, and CV were risk factors for asymptomatic hypoglycemia. Moreover, MAGE has some predictive value for the occurrence of asymptomatic hypoglycemia.
