Journal of Chinese Physician 2015;17(4):513-515,518
Objective To explore the correlation of urinary albumin/creatinine ratio (urinary albumin-to-creatinine ratio,UACR) and blood pressure in young people.Methods Totally 200 cases of hypertensive patients (aged 18 ~50 years old) from January 2012 to March 2014 and 200 healthy volunteers who had medical examination in our hospital were selected with a random sampling method for staff questionnaires,biochemical tests,and physical examinations.Biochemical tests included kidney function,blood glucose,blood lipids,blood uric acid,and UACR.First,400 cases were divided into four groups (1,2,3,and 4 groups) according to UACR quartiles from low to high.Second,400 cases were divided into three groups according to their blood pressure:normal blood pressure,prehypertension,and hypertension.The correlation of UACR and different groups of blood pressure was analyzed.Results For norm blood pressure group,prehypertension,hypertension,the corresponding UACR level (median:25% ~ 75% quartile) was 0.8 (0.6 ~ 1.2) mg/mmol,0.9 (0.7 ~ 1.4) mg/mmol,1.0 (0.8 ~ 1.7) mg/mmol;positive UACR rate was 0,2.6%,and 34.7%,three groups UACR levels and positive UACR rate index differences were statistically significant (P <0.05).After age factor was adjusted for 400 cases,both systolic and diastolic blood pressures were positively correlated with UACR levels.After body mass index,age,total cholesterol,and low-density lipoprotein cholesterol were adjusted for 400 cases,compared to group 1,the ratio of prehypertension to hypertension (95% confidence intervals) in groups 2,3,and 4 was 0.98 (0.80 ~ 1.20),1.29 (1.05 ~ 1.58),and 1.86 1.52 ~2.28).Conclusions Urinary albumin/creatinine ratio was positively correlated with prehypertension and hypertension in young people.
2.Network pharmacology: new opportunity for the modernization of traditional Chinese medicine.
Acta Pharmaceutica Sinica 2012;47(6):696-703
Traditional Chinese medicine (TCM) with the characteristics of holistic view and treatment based on syndrome differentiation, has rich clinical experience thousands of years and demonstrates promising effects to cure complex disease. However, due to the features of multi-component, multi-target and synergistic effect existed in TCM, the effective substances and mechanisms of action are not clear, the qualities of TCM are out of control, and scientific and correct assess system is waiting to be established. The network pharmacology is a novel subject based on the construction of multi-layer networks of disease-phenotype-gene-drug to predict the drug targets in a holistic view, and promote efficiency of drug discovery. Methodologically, network pharmacology integrated the notions of comprehensive research and systematic assessment which agree with the characteristics of holistic view and treatment based on syndrome differentiation in Chinese medicine. Our paper reviewed the challenge and chance within the modernization of TCM, the concept and technology of network pharmacology, and its preliminary application in investigation of TCM. The theoretical system of network pharmacology is emphasized, and the potential prospect of its application in modernization in TCM is focused.

Objective To investigate the effects of continuous spinal anesthesia with different concentrations and doses of ropivacaine on the ultrastructure of the spinal cord and nerve roots. Methods Twenty-four male SD rats weighing 220-280 g were anesthetized with intraperitoneal 10% chloral hydrate 300-350 mg/kg. A polyurethane microcatheter was inserted into the lumbar subarachnoid space according to the technique described by Yaksh. An 8-cm catheter segment was left in the subarachnoid space. The animals were randomized to receive normal saline, 0.5%, 0.75% or 1.0% ropivacaine 40 ? 1 intrathecally 3 times at 1.5 h interval. Six hours after the first intrathecal administration the animals were decapitated and L1 ,2 segment of the spinal cord and nerve roots were immediately removed for electron microscopic examination. Results Electron microscopic examination revealed that in animals which received intrathecal (i.t.) normal saline, 0.5% or 0.75% ropivacaine the neurolemma of the nerve roots and the mitochondria and endoplasmic reticulum of the neurons in the spinal cord were intact, while in animals which received i.t. 1.0% ropivacaine the neurolemma was stratified and partly disrupted and there were swelling of endoplasmic reticulum and vacuole degeneration. Conclusion Six hours continuous spinal anesthesia with 1.0% ropivacaine may be injurious to the spinal cord and nerve roots.
