Objective To explore the value of combined measurement of urine N-acetyl-beta-D-glucosaminidase (NAG) activity and serum Cystatin C in diagnosing diabetic nephropathy (DN) in early phase. Methods Sixty-two cases with type 2 diabetes (diabetic group) were divided into three groups according to their 24 hours urinary albumin excretion (24hUAE) : group A (normal albuminuria, 20 cases), group B (microalbuminuria, 22 cases) and group C (macroalbuminuria, 20 cases). Furthermore, 30 healthy people were involved in control group. 24hUAE,NAG,serum creatinine (SCr) and serum Cystatin C were measured, and endogenous creatinine clearance rate (Ccr) was calculated by Cockcroft-Gault formula. All these indexes among three groups were compared. Results The levels of urinary NAG activity and serum Cystafin C in diabetic group was significantly higher and Ccr was significantly lower than those in control group(P < 0.01). The levels of urinary NAG activity and serum cystatin C gradually increased in group A, B and C(P< 0.05 or < 0.01). While no significant difference was observed between group A and group B in the level of SCr (P > 0.05). There were significant positive correlations among the levels of urinary NAG activity, serum Cystatin C,24hUAE and SCr (P< 0.01),and all above showed negative correlations with Ccr (P<0.01). Co-detection of urinary NAG activity and serum Cystatin C had significantly higher positive rate [80.6%(50/62)] than single one [58.1%(36/62),61.3%(38/62)](P<0.05). Conclusion Co-detection of urinary NAG activity and serum Cystatin C may indicate early renal damage in DN, and it is valuable in diagnosing DN in early phase.

Objective: To explore the expression of epidermal growth factor receptor(EGFR) protein during benzo(a)pyrene (BaP) induced carcinogenesis. Methods: This study, we firstly utilized immunofluorescence assay and Western-blot to examine EGFR expression of the BaP which was constructed previously by project team induced malignant transformation human bronchial epithelial cell (BTC) and the control (16HBE cell). Then, we selected 36 healthy SD rats, divided into two groups according to simple random method, 18 rats each group. The constructed rat lung neoplasm model induced by pulmonary injection of BaP (10 mg/ml of BaP solution in 0.2 ml corn oil), contrast group use 0.2 ml corn oil, lung tissue was collected and the EGFR expression of lung tissue was detected by immunofluorescence assay and Western blot. T analysis was used to test the different of EGFR between two groups. Results: Immunofluorescence analysis showed that the EGFR expression in BTC was significantly higher than 16HBE cell. Meanwhile, Western blot also was used to confirmed this result, the relative expression of EGFR protein in the rats of the model group the control group were 1.04±0.13 and 2.32±0.12, respectively, and the difference was statistically significance (t=12.39, P<0.001). In vivo, well-defined tumor was found in the rat with pulmonary injection of BaP, and the lung showed diffuse alveolar septal thickening, alveolar wall destruction and pulmonary alveoli fusion, which suggested that the rat lung neoplasm model was constructive successfully. Furthermore, we found the EGFR expression of lung was increased dramatically in the rat lung neoplasm model by immunofluorescence detection and Western blot. The relative expression of EGFR protein in the rats of the model group the control group were 0.21±0.03 and 1.30±0.07, respectively, and the difference was statistically significance (t=12.84, P<0.001). Conclusion Expression of EGFR protein was increased during BaP carcinogenesis, and EGFR may play an important role in the carcinogenesis of BaP.

Objective:To explore the application and effect of artificial intelligence technology in perinatal management of gestational diabetes mellitus.Methods:240 pregnant women with gestational diabetes diagnosed during 24-26 weeks of pregnancy in Changsha Maternal and Child Health Hospital were prospectively selected and randomly divided into control group (120 cases) and observation group (120 cases). The control group used the traditional management mode for nutritional management, and the observation group used AI technology for nutritional management. The weight gain, blood glucose control level, insulin use, pregnancy complications, pregnancy outcome and other indicators of the two groups were compared.Results:(1) Monitoring indicators during pregnancy: there was no significant difference in weight gain between the two groups ( P>0.05). The proportion of weight gain in the appropriate range in the observation group was significantly higher than that in the control group ( P<0.05); The prevalence of full-term anemia, insulin use rate and the incidence of blood glucose exceeding the control standard in the observation group were significantly higher than those in the control group (all P<0.05). (2) Pregnancy outcome: there was no significant difference in the incidence of gestational hypertension, cesarean section, fetal growth restriction, premature delivery and neonatal hypoglycemia between the two groups (all P>0.05); The incidence of conversion to cesarean section, macrosomia, neonatal blood glucose <2.6 mmol/L, mild asphyxia and admission to neurosurgical intensive care unit (NICU) in the observation group were significantly higher than those in the control group (all P<0.05). Conclusions:Application of AI technology to nutritional management of gestational diabetes can better control the maternal perinatal weight gain and blood glucose level, reduce the incidence of anemia in the third trimester of pregnancy, the incidence of macrosomia, the use of insulin and the rate of conversion to cesarean section, and improve the neonatal outcome.
