Diabetic kidney disease (DKD) is a serious long-term complication and major death cause of patients who have suffered from diabetes mellitus (DM),which is a serious threat to the health of human being.Professor Zhao Zongjiang first came up with the of DKD "consumptive kidney disease" scientific theory,and led the scientific research team for DKD research.Our team had achieved some results,which were mainly focused on the animal experiments and cell culture experiment.And the research fields covered pharmacodynamics,oxidative stress levels and signal transduction pathways.Focusing on the reduction of extracellular matrix in the glomerular mesangial area and tubulointerstitial deposition,inhibition of podocyte injury,inhibition of podocyte apoptosis,inhibition and reversal of podocyte transdifferentiation,inhibition of renal tubular epithelial cell transdifferentiation and other scientific issues,this paper systematically explored the biological mechanism of DKD "consumptive kidney disease" scientific theory.This paper explained how "consumptive kidney disease" scientific theory was proposed and summarized related research results of our research team and developed traditional Chinese medicine (TCM) theory by supplying the TCM "consumptive organ disease" theory.

This study was aimed to explore the renoprotective effects of Tang-Shen-Ping (TSP) on RhoA/ROCK signaling pathway in KKAy mice with diabetic kidney disease (DKD).A total of 60 female 10-week SPF degree KKAy mice,which were fed with KK special food for 10 weeks,were made into DKD model.Mice were randomly divided in the model group,irbesartan group,low-,medium-and high-dose TSP group (0.525 g· kg-1,1.05 g· kg-1,and 2.1 g· kg-1).Ten female C57BL/6J mice were used as the normal control group.Mice of each group were intragastrically administered with corresponding medicine,respectively,while mice of the control group and the model group were given deionized water of the equal volume.The body weight was measured and the 24-hour urine protein quantification was detected every 4 weeks.At the end of the 26th week,all mice were sacrificed and the biochemical indicators,such as fasting blood glucose (FBG),serum blood urea nitrogen (BUN),serum creatinine (Scr),and triglyceride (TG) were measured.HE staining,Mallory staining and PAS staining were used to observe the pathological morphology of kidney tissues.Immunohistochemistry (IHC) and in situ hybridization (ISH) were used in the detection of transforming growth factor-β1 (TGF-β1),Ras homolog gene family member A (RhoA),Rho-associated coiled-coil-containing protein kinase 1 (ROCK1),α-smooth muscle actin (α-SMA),E-Cadherin (E-Cad) mRNA and protein expression.The results showed that compared with the model group,there were significant differences on body weight,the ratio of kidney weight to body weight,and urinary protein in the middle-and high-dose TSP group (P ＜ 0.01);the renal pathological damage was obviously decreased;contents of FBG,BUN,Scr and TG decreased (P ＜ 0.01);mRNA and protein expression of E-Cadherin increased;mRNA and protein expression of TGF-β1,RhoA,ROCK1 and α-SMA decreased with significant difference in the middle-and high-dosc TSP group (P ＜ 0.01).It was concluded that the renoprotective effects and epithelial-mesenchymal transdifferentiation (EMT) of renal tubular epithelial cells of TSP on DKD KKAy mice may be related to the regulation of RhoA/ROCK signaling pathway.

Based on analyzing the connotation and essence of the Westward Relocation Spirit and its unique expression and value in the medical field,through strengthening the professional identity and sense of honor of medical staff,this research optimizes the working environment and treatment of medical staff,enhances the training of their professional literacy and skills,boosts measures including the mental health and care of medical staff,so as to develop the sense of gain of medical staff to enable them to better perform their duties,and make contribution to the improvement of people's health and sharing of good doctor-patient relations.

Objective: To explore the association between the frequency of prenatal care in childbearing aged women and risk of small for gestational age (SGA) among neonatal twins in Shaanxi Province. Methods: From July to December 2013, a total of 30 027 childbearing aged women, who were pregnant from January 2010 to November 2013 and had definite outcomes, were selected from 30 districts (counties) of Shaanxi Province by using the multi-stage random sampling method. The questionnaires with a face-to-face survey method were used to retrospectively collect demographic information, pregnancy history, lifestyle during pregnancy, disease history, nutritional supplements, and health care during pregnancy. Information on the gestational age and birth weight of the newborn were obtained by consulting the medical certificate of birth and were registered as twin A and twin B by birth order. Finally, 356 childbearing aged women and their twin babies with complete data were included in the analysis. A generalized estimation equation model was used to analyze the association between the frequency of prenatal care and the risk of SGA among neonatal twins. Results: The age of childbearing aged women was (27.44±4.68) years old, of which 79.49% (283 women) were rural residents and 44.38% (158 women) had seven or more times prenatal care. The gestational age and birth weight were (37.64±2.51) weeks and (2 510±497) g, respectively. The prevalence of SGA was 51.40% (183/356) for twin A and 53.37% (190/356) for twin B, respectively. The prevalence of SGA was 44.30% (70/158) for twin A with seven or more times prenatal care and 42.41% (67/158) for twin B with seven or more times prenatal care, which was lower than that for twins with less than seven times prenatal care, respectively [57.07% (113/198) and 62.12% (123/198)] (P values were 0.017 and <0.001). The results of generalized estimation equation model suggested that compared to those with less than seven times prenatal care, after adjusting for parity, birth order, place of residence, maternal age, occupation, education, family wealth index, passive smoking, pregnancy-induced hypertension syndrome, folic acid, and iron supplement during perinatal period, and gender of the newborn, the OR (95%CI) of risk of SGA among childbearing aged women with seven or more times prenatal care was 0.60 (0.40-0.91). Conclusion Seven or more times prenatal care could reduce the risk of SGA among neonatal twins in Shanxi Province.
