Diabetes mellitus is a worldwide public health problem,which is a serious threat to human health.WHO released the global diabetes report shows Chinese incidence of type 2 diabetes was explosive growth in the past few decades,but public awareness of diabetes is generally inadequate,especially at the grassroots level.Therefore,it is imperative to regulate the basic level of diabetes diagnosis and treatment.As one of the basic measures of diabetes treatment in our country,education and management of diabetes' foundation is weak,mainly for the lack of national basic medical and health institutions,dull form of education and lack of target,shortages of specialized diabetes staff.So in order to safeguards the success of primary diabetes education and management and improve the prevention of primary diabetes,it is necessary to establish a sound mechanism of reward system,make full use of various payment platform,strengthen the basic management of diabetes monitoring information construction and carry out the Internet education measures.This article reviews the current situation of education and management of primary diabetes.

Objective To explore the clinical characteristics in patients with histiocytic necrotizing lymphadenitis (also called Kikuchi-Fujimoto' s disease,KD) and meningitis.Methods We reported a patient who developed meningitis preceding the other presentations of KD with abnormal serum autoimmune phenomena,and systematically reviewed 19 cases of KD with meningitis that had been reported worldwide,and analyzed the clinical parameters and treatments.Results The present case was a 25-year-old female subject with serum antinuclear factor antibody and anti-ribonucleoprotein antibody positive.The patient recovered after treatment with steroid and no recurrence was appeared.Among the 19 patients,the average age was 20.2 years,sex ratio was 10:9 (10 female:9 male),7 patients had abnormal serum autoimmune phenomena,7 patients'initial symptom was meningitis and 5 patients were administrated with steroid.Conclusions The onset age in KD with meningitis is earlier than the common KD,and sex ratio in KD with meningitis is close to 1∶ 1.A definitive diagnosis of the disease is determined by a lymph node biopsy at present.

Objective:To evaluate the clinical effectiveness and safety of combined face and neck injections of botulinum toxin type A to improve face and neck aging.Methods:From January 2020 to January 2023, 30 female patients with age of 29-66 years, average (42.2±8.8) years, underwent face and neck combined injection of A-type botulinum toxin in the Department of Dermatology, Henan Provincial People′s Hospital. The injection sites included the forehead, between the eyebrows, around the eyes, the dorsum of the nose, and the mandibular margin, etc. The efficacy was assessed by the wrinkle severity scale (FWS) and the AB value of the distance from the lowest point of the mandibular margin on the midline of the hemiface to the level of the medial canthus at 4 and 24 weeks after the injection, as well as the subjective degree of improvement by the Global Aesthetic Improvement of the Face Scale (GAIS) and the Self-perception of Age (SPA), and the satisfaction of the patients and post-injection adverse reactions.Results:At 4 weeks after the injection, the total effective rate of improvement of wrinkles in all parts of the upper face was 100% (30/30), and there was a statistically significant difference in the improvement of AB ( t=28.35, P<0.05). At 24 weeks after the injection, the total effective rate of improvement of wrinkles in all parts of the upper face ranged from 16.7% (5/30) to 36.7% (11/30), and the improvement of AB still showed a statistically significant difference ( t=3.98, P<0.05). 100% (30/30) and 66.7% (20/30) of patients assessed their facial status as improved on GAIS at 4 and 24 weeks after the injection, respectively, and 100% (30/30) and 63.3% (19/30) of patients perceived themselves as younger. Patient satisfaction was 100% (30/30). After injection, there were 5 cases of slight ecchymosis at the injection site and 1 case of weakness in eyebrow elevation in the 30 patients, which disappeared on their own within 1 to 2 weeks. Conclusions:The therapeutic effect of face and neck combined injection of botulinum toxin type A on facial rejuvenation is obvious, with high patient′s satisfaction and no serious adverse reactions.

Objective To investigate the relationship of lacunar infarction (LI) and white matter lesion with cognitive impairment in patients with subcortical ischemic vascular disease (SIVD) Methods Fifty-three patients were diagnosed as SIVD according to the criteria of Erkinjuntti. The symptoms and signs were recorded by an interview and examination, and neuropsychological assessment and magnetic resonance imaging (MRI) were performed. A semi-automated MRI quantitative method was used to measure the volume of white matter hyperintensity (WMH) and the number of LI was counted. Correlation and the partial correlation analysis were performed to examine the relationship of general cognitive function with the volume of WMH and the number of LI. Results The pseudobulbar paralysis symptom and the upper motoneuron injury sign were the most common in these patients (18.9% and 37.7%). Correlation analysis showed that there was positive correlation between the volume of WMH and age (r = 0. 518, P < 0. 05), and there was negative correlcction between mini-metal state examination (MMSE) scures and the volume of WMH (r=-0.514, P<0. 05), After controlling confounding factors, only age was positively correlated with the volume of WMH (r=0. 400, P=0. 004). There were negative correlation between the number of LI, the volume of WMH and MMSE scores(r=-0. 456,-0. 514,-0. 385,-0. 382;all P<0. 05), and the years of education was positively correlated with MMSE scores (r= 0. 518, P< 0. 001). Conclusions Age may not be the main risk factor for cognitive impairment in patients with SIVD. The volume of WMH and the number of LI are independent risk factors for cognitive impairment in patients with SIVD. Patients with severer SIVD or more LI show poorer performance on cognitive function.
