1.The diagnosis and treatment of critical illness-related corticosteroid insufficiency
Chinese Pediatric Emergency Medicine 2011;18(5):460-462
In recent years,relative adrenal insufficiency in critical patients has become a hot issue.With progression of studies,this definition is insufficient in accuracy.Thus a new definition of critical illnessrelated corticosteroid insufficiency(CIRCI)is developed.Now CIRCI have not had consentaneous diagnostic criteria.Moreover,the benefits of this diagnose to corticosteroid treatment in critical patients remains unclear.This article will review on the diagnosis of CIRCI and current situation of corticosteroid treatment.

Objective To assess nutritional status of critically ill children,and to investigate the correlation of nutritional status with illness severity and clinical outcomes,so as to provide a theoretical basis for rational nutrition support of critically ill children.Methods All patients hospitalized in the pediatric intensive care unit of Beijing Children's Hospital from November,2010 to January 2011 were enrolled and studied prospectively.We collected anthropometric parameters (body length/height,body weight,head circumference,etc) for nutritional assessment,as well as their clinical data such as underlying diseases,pediatric risk of mortality scores (PRISM),length of hospital stay and mechanical ventilation duration.Results tn 196 cases,the prevalence of malnutrition was 21.9% (43/196).Malnutrition group had greater PRISM scores,higher mechanical ventilation rate and a lower 28-day survival rate than normal nutritional status group (all P < 0.05).Conclusions The prevalence of malnutrition on admission to the PICU was high and poor nutritional status indicated greater illness severity and adverse clinical outcomes

Objective To investigate the prevalence of vitamin D deficiency and to examine its relationship with the severity and prognosis in the critically ill children. Methods A total of 83 critically ill children admitted from November 1,2010 to December 9,2010 to Pediatric Intensive Care Unit in Beijing Children's Hospital,Capital Medical University were enrolled in the study. Serum 1,25 - Dihydroxyvitamin D concentration was measured by using an en-zyme - linked immunosorbent assay(ELISA). Anthropometric parameters such as height/ length and weight of the chil-dren were measured. Data collection also included primary disease,Pediatric Critical Illness Score(PCIS),the Pediatric Risk of Mortality Ⅲ(PRISM Ⅲ)score,multiple organ dysfunction syndrome( MODS)rate,mechanical ventilation rate,time of hospital of stay and the 28 - day survival rate. Results There were 32 cases with vitamin D deficiency on admission,vitamin D deficiency rate on admission was 38. 6% ,and there was no statistically significant difference among different primary disease groups(P = 0. 815). Vitamin D deficiency rate of malnutrition group was lower than that of the normal group[60. 0%(12 / 20 cases)vs 40. 0%(8 / 20 cases),χ2 = 5. 989,P = 0. 014]. PCIS scores of those with a normal vitamin D status was higher than those of the vitamin D deficiency group,showing a significant difference [(80. 47 ± 6. 18)scores vs(77. 16 ± 7. 59)scores,P = 0. 022]. PCIS score was positively correlated with the vitamin D level(r = 0. 267,P = 0. 015). There was no statistically significant difference among the PRISM score,MODS rate, mechanical ventilation rate,hospital stay length and the 28th day survival rate between the normal vitamin D group and the vitamin D deficiency group(all P ﹥ 0. 05). Conclusions A high prevalence of vitamin D deficiency is found in the critically ill children. The prevalence of vitamin D deficiency in children with malnutrition is higher. Vitamin D status may be correlated to the severity of the critically ill children,but the association with the prognosis is not obvious.

Patients with radioactive enteritis generally have certain intestinal microecological imbalance. Traditional Chinese Medicine (TCM) has showed good advantage in regulating intestinal microbial flora. In clinical practice, patients are treated based on syndrome differentiation of heat toxin damaging collaterals, cold-heat mixed syndrome, spleen deficiency and dampness stagnation, spleen and kidney yang deficiency, yin deficiency and body fluid deficiency. The Baitouweng Decoction, Wumei Pill, Sijunzi Decoction are the common prescriptions. TCM can promote the balance of intestinal microecology and treat digestive diseases such as radioactive enteritis, by improving the abundance of intestinal flora, inhibiting the level of inflammatory cytokines, and playing the role of probiotics and immune regulation.

To construct, express and purify Exendin-4 analogue and detect its biological activity in vivo. Insert gene sequence into fusion partner ofpED plasmid which is helped to purification, entitled the new recombinant plasmid 5 Exendin-4 analogue polypeptide gene and fusion partner gene was linked by acid hydrolysisgene, transformed to E. coli BL21 and the fusion protein was induced by lactose. After acid hydrolysis, the Exendin-4 analogue polypeptide separated from fusion chaperon. Anion charge chromatography were used to further purification. 6 to 8 week-old ICR mice were injected (s.c) with Exendin-4 analogue, blood glucose and plasma insulin level was detected in different period after oral glucose tolerance test. The results show that high expression of inclusion body was induced by lactose, which accounted for 40% of germ proteins, the Exendin-4 analogue was obtained with the purity of 91.8% after being purified by anion charge chromatography. Bioactivity assay showed that the level of blood glucose of mouse which treated with exendin-4 analogue was obviously decreased to normal (P < 0.01), and the level of plasma insulin was increased obviously (P < 0.01).

ObjectiveTo investigate the impact of yang deficiency syndrome on the progression to end-point events of diabetic kidney disease (DKD). MethodsA retrospective study among patients with stage Ⅳ DKD admitted to Dongzhimen Hospital of Beijing University of Chinese Medicine from September 1st, 2016 to September 30th, 2021 was conducted. Data on the patients' general information, clinical indicators including duration of diabetes, duration of proteinuria, history of smoking and drinking, hemoglobin (HGB), fasting blood glucose (FBG), albumin (ALB), serum creatinine (Scr), urea nitrogen (BUN), uric acid (UA), cholesterol (TC) , triglycerides (TG), low-density lipoprotein (LDL), 24-hour urine protein quantification (24h-UTP) and estimated glomerular filtration rate (eGFR), and TCM syndromes including symptoms, tongue and pulse, and syndrome scores were collected. The patients were divided into exposure group (yang-deficiency group) and non-exposure group (non-yang-deficiency group). The general information, clinical indicators and incidence rates of end-point events were compared, and the impact of yang deficiency syndrome on the end-point events of stage Ⅳ DKD was analyzed. Survival analysis was performed using Kaplan-Meier method, and multivariate Cox proportional risk models were used to identify independent predictors of end-point events. ResultsA total of 160 patients with stage Ⅳ DKD were included in the study, including 43 cases of yang deficiency syndrome and 117 cases of non-yang deficiency syndrome. Compared to those in the non-yang deficiency group, the waist circumference, BUN and the incidence of end-point events in the yang deficiency group were significantly higher (P<0.05 or P<0.01). Spearman correlation analysis showed that yang deficiency syndrome was positively correlated with incidence of end-point events of stage Ⅳ DKD (r = 0.167, P = 0.035). Furthermore, 24h-UTP and BUN levels were also positively correlated with end-point events in stage Ⅳ DKD patients (P<0.01), while ALB and HGB levels were negatively correlated (P<0.01). Kaplan-Meier survival curves showed that yang deficiency syndrome was associated with an increased risk of end-point events (Log Rank P = 0.011). Moreover, 24h-UTP levels ≥3500 mg, BUN level ≥8 mmol/L, ALB level <30 g and HGB level <11 g were all associated with the increase of the risk of end-point events (P<0.05 or P<0.01). Multivariate Cox regression analysis showed that yang deficiency syndrome was an independent risk factor for patients with stage Ⅳ DKD to progress into end-point events (HR = 2.36, 1.32 to 4.21; P = 0.004), as well as 24h-UTP ≥ 3500 mg, BUN ≥ 8 mmol/L, HGB<11 g and ALB<30 g (P<0.05 or P<0.01). ConclusionsFor stage Ⅳ DKD, patients with yang deficiency syndrome are more likely to have end-point events, which is an independent risk factor for the progression into end-point events.
