For promoting the quality evaluation of Gardenia resource,a UPLC method for the determination of 4 compounds (geniposidic acid,geniposide,crocin-1 and crocin-2) in Gardeniae Fructus was established.The UPLC separation was performed on an Waters Acquity UPLC BEH-C18 (2.1 mm× 100 mm,1.7 μm) column eluted with the mobile phases of acetonitrile-0.1％ formic acid solution in a gradient mode at a flow rate of 0.3 mL· min-1.The detection wavelengths were 240 nm and 440 nm,respectively.Under the optimum conditions,the calibration curves of four analysis were linear in the range of 0.0065-0.0096 μg· mL-1,with correlation coefficients more than 0.9995.The limits of detection (LODs) of four analysis were in the range of 0.0386-0.1875 μg· mL-1.As the results of determination of 4 compounds of 12 batches of Gardeniae Fructus showed,there was great differences between the contents of the 4 compounds,the contents of geniposide were 2.44％-6.96％,while the contents of crocin-1 were 1.26％-3.04％.In addition,fingerprints of 12 batches of Gardenia resources were built using ChemPattern software,and analysis and exploration over the detection results of several samples were carried out using multivariate statistical method (similarity analysis,principal component analysis and cluster analysis).The present study provided a reference to value the importance of this method in the quality evaluation and quality control of Gardeniae resources and slices.

Objective To analyse the kidney damage situation of the elderly health examination people,and identify its characteristic.Methods A cross-sectional study was held which enrolled 1088 elderly health examination people.Urine routine,random urine albumin/creatinine ratio (ACR),serum creatinine,urea nitrogen were detected by biochemical analyzer,and estimated glomerular filtration rate (GFR) with CKD-EPI formula.Kidney structure change was examined by Color doppler ultrasound detector.Results The prevalence of hypertension,hyperlipemia,diabetes mellitus was 61.5％,62.1％,11.6％,respectively.The abnormal detection rate of urine routine was 19.0％,including 2.6％ proteinuria,14.1％ hematuresis and 5.4％ leucocyturia.The abnormal detection rate in the people with was higher than those without (P＜0.01).However,the albuminuria detection rate with random urine ACR was 25.1％,obviously higher than that of urine routine (P＜0.01).The ultrasound results showed that 6.8％ of the total were examined with elderly characteristic kidney change,the proportion of renal cyst was the highest,accounted for 21.8％.70.7％ of all people were in the level of eGFR more than 60 ml· min-1 · 1.73 m-2.The level of eGFR＜60 ml· min-1 · 1.73m-2 in the people with was higher than those without (P＜0.01).eGFR was declined with age.When age increased every 10 years,eGFR was decreased 7 ml · min-1 · 1.73 m-2.Conclusions No matter in structure or function,the elderly people's kidney damage has its characteristic.We should make it clear to correctly diagnose and cure elderly kidney disease.

ObjectiveTo observe the effects of electroacupuncture on IL-1β in brain tissue of rats after total cerebral ischemia-reperfusion.MethodsThirty male Wistar rats were randomly divided into the sham operation group, model group and acupuncture group, in each group. In acupuncture group and model group, 4-vessel-occlusion method was used to make a rat model of cerebral ischemia reperfusion. Acupuncture group used electroacupuncture on points Quchi and Zusanli, 6 hours after reperfusion. The rats of each group were killed and ELISA was used for the measurement of IL-1β in brain tissues.ResultsIL-1β in brain tissue in model group increased significantly compared with sham operation group and acupuncture group(P<0-001). No significant differences were found between sham operation group and acupuncture group (P>0-05).ConclusionAcupuncture can lower IL-1β content of brain tissue of rats with brain ischemia/reperfusion injury.

Objective To explore whether IL-27 inhibited the pulmonary fibrosis through regulating the expression of TGF-β/Smad signaling pathway in the bleomycin-induced pulmonary fibrosis model. Methods Forty male C57/BL6 mice were randomly divided into normal control group(group A),bleomycin-induced pulmonary fibrosis group(group B),bleomycin+IL-27 group(group C)and bleomycin+IL-27 antibody group(group D) with 10 in each. Five mice in each group were sacrificed on days 7 and 28 after with intratracheal bleomycin. TGF-βR1,Smad1 and Smad3 in right lung tissue were measured by Western Blot. Results 1. In the bleomycin-induced pulmonary fibrosis model,the expression of TGF-βR1 was higher on days 7 and 28,which was inhibited by IL-27. 2. The expressions of p-Smad1 and p-Smad3 were highest in group D on days 7 and 28, but were lower in group C on day 7 than those in group B. Conclusion Exogenous IL-27 might alleviate pulmonary fibrosis through inhibiting the related protein phosphorylation in TGF-β/Smad signaling pathway.

Hyperparathyroidism is a common endocrine disease that seriously affects human health, depending on its etiology, which can be divided into three types: primary, secondary and tertiary. In clinical practice, we found that some primary hyperparathyroidism may be secondary or tertiary hyperparathyroidism caused by insufficient calcium intake and/or vitamin D deficiency/insufficiency, and become a common type of hyperparathyroidism. The daily calcium intake of Chinese people is generally insufficient. Vitamin D can promote the absorption of calcium, but vitamin D deficiency/insufficiency is also a worldwide public health problem. Long-term hypocalcemia will stimulate parathyroid hyperplasia and secrete excessive parathyroid hormone, resulting in parathyroid hyperfunction (pre-hyperparathyroidism) and then secondary hyperparathyroidism, both of which may damage bone and release calcium into blood, leading to diseases of multiple organs and tissues. The detection of bone metabolism indexes such as calcium, magnesium, phosphorus, parathyroid hormone and vitamin D may be helpful for the early diagnosis of pre-hyperparathyroidism and hyperparathyroidism. Supplementation of calcium and vitamin D in early stage can control the development of the disease and change "unpreventable and uncontrollable" into "preventable and controllable" . The health screening of bone metabolism indexes and parathyroid ultrasonography should be advocated, and the prevention and treatment of calcium and/or vitamin D insufficiency associated parathyroid hyperfunction and hyperparathyroidism should be strengthened, so as to greatly improve the bone health, urinary calculus, metastatic vascular calcification and systemic abnormal calcium migration and precipitation in the population.

Differentiated thyroid cancer is one of the most common endocrine malignant tumors, and thyroidectomy is its basic treatment measures. Insufficient attention is paid to its postoperative bone hungry syndrome and parathyroid hyperfunction or hyperparathyroidism, which will seriously affect the patient’s life quality and prognosis. This paper will explore the etiology, dangers, diagnosis, prevention, and treatment for hungry bone syndrome, parathyroid hyperfunction and hyperparathyroidism of thyroid cancer patients after thyroidectomy.

Metastatic vascular calcification and calcinosis universalis, as severe complications of parathyroid hyperfunction and hyperparathyroidism, have attracted more attention in patients with renal secondary hyperparathyroidism and primary hyperparathyroidism. But, they are of little concern in patients with long-term negative calcium balance related parathyroid hyperfunction or hyperparathyroidism caused by calcium and/or vitamin D insufficiency (CVI). CVI is common in the population. Relatively low level of serum calcium and negative calcium balance caused by long-term CVI result in parathyroid hyperfunction or hyperparathyroidism, which may cause secretion of PTH beyond the physiological level, leading to bone absorption and release of a large amount of bone calcium into the blood. It may not only cause bone loss and osteoporosis, but also form metastatic vascular calcification or calcinosis universalis presented by cardiovascular diseases and other multi-organ lesions. Early calcium deposition can gradually fade after reasonable treatment, but middle arterial calcification is not easy to fade once it occurs. Therefore, vascular calcification and calcium deposition should be actively prevented and early screened and diagnosed. The early prevention, diagnosis and treatment of parathyroid hyperfunction or hyperparathyroidism can prevent, delay, or even reverse the occurrence and development of metastatic vascular calcification and calcinosis universalis, which is significant for disease prevention and protecting the patients' health influenced by these diseases.
