OBJECTIVETo explore the correlation between pathological characteristics of target organs and excess evil syndrome in IgA nephropathy.

METHODSData were collected in multicenter cooperation. Totally 266 IgA nephropathy patients were typed into exogenous wind-heat affection syndrome (49 cases), lower energizer damp-heat syndrome (100 cases), damp-phlegm syndrome (43 cases), and blood stasis syndrome (74 cases). Meanwhile, percutaneous renal biopsy was performed in all patients for Hass classification, Oxford classification, Katafuchi integral, and Jiang's classification methods. The correlation between excess evil syndrome and pathological index was analyzed.

RESULTSFour syndrome types were correlated with their Hass levels (r = 0. 341, P <0. 01). Affection of exogenous wind-heat syndrome was correlated with segmental proliferation of endothelial cells and damaged active lesions of segmental capillary loops. Lower-energizer damp-heat syndrome was associated with Hass III level, destroying active lesions of capillary loops, segmental proliferation of endothelial cells, glomerular segmental lesions, focal interstitial infiltration of inflammatory cells, focal interstitial fibrosis and tubular atrophy. Blood stasis syndrome was associated with Hass IV level, glomerular sclerosis, segmental glomerulosclerosis (S)/adhesion, mesangial hypercellularity (M), angiohyalinosis, multi-foci interstitial infiltration of inflammatory cells, multi-foci interstitial fibrosis and tubular atrophy. Phlegm-damp syndrome had higher proportions of Hass I and III levels, but with no association with other pathological parameters.

CONCLUSIONSExcess evil syndrome was associated with partial pathological characteristics of IgA nephropathy. It could reflect pathological damage degree of target organs, activities, chronic lesions, and prognosis of IgA nephropathy to certain extent. Correlated pathological characteristics and its evolution could indicate excess evil syndrome types and their evolution rules.

OBJECTIVETo investigate the absorption characteristics and transportation mechanism Yangyin Tongnao granules in main effective fractions in Caco-2 cell model.

METHODThe safety concentrations of Yangyin Tongnao granules in main effective fractions in Caco-2 cells. A Caco-2 cell model was established to study the transport situations after the compatibility of Yangyin Tongnao granules in main effective fractions, and the content was determined by high performance liquid chromatography (HPLC).

RESULTP(app) of puerarin, ligustrazine and astragaloside were less than 1.0 x 10(-6) cm x s(-1), and their P(app) were hard to be close to atenolol. The oral absorption in descending order is shown as the following: puerarin, ligustrazine, astragaloside. After the compatibility between saponins and flavonoids, P(app) of astragaloside was improved obviously, which promoted the transport from apical (AP) to basolateral (BL); the compatibility of puerarin, ligustrazine and astragaloside showed a significant effect in the efflux of astragaloside and no change in the absorption transport of ligustrazine and puerarin at the same time. There is a great difference in bidirectional transport of representative component of each effective fraction, and P(app)(B --> A) was significantly greater than Papp(A --> B), which suggested that the efflux transport from BL side to AP side had an advantage in the three representative components of the three effective fractions in Caco-2 cell monolayer model.

CONCLUSIONAstragaloside, ligustrazine and puerarin may be malabsorptive compounds, and the three compounds may be discharged by the transport protein in small intestine membrane.

Objective The proportion of multiple drugs and the irrational use of drugs increased significantly in the elderly patients (over 80 years). This study aimed to investigate the occurrence of potentially inappropriate medication (PIM) and analyzed the possible reasons related to PIM in elderly patients. Methods In this study,918 cases from Cadre Ward I of Research Center for Geriatrics of Nanjing General Hospital of Nanjing Military Region were selected from January to December in 2016. According to the Beers Criteria (Version 2015),we evaluated PIM in four subtypes,type 1 that is not related to the state of disease in elderly patients, type 2 that is related to the state of disease in elderly patients,type 3 which should be used carefully,and type 4 which is the inappropriate combination of non-anti-infective Drugs. The PIM influence factors were analyzed by logistic regression analysis. Results There are 521 cases (56.75%) of type 1 PIM. The first 3 drugs are Short and medium acting benzodiazepams,PPI and long acting benzodiazepams. There are 206 cases (22.4%) of type 2 PIM. The first 2 drugs are drugs associated with insomnia (oral hyperemia, stimulants, theo-phylline and caffeine) and drugs associated with dementia or cognitive impairment (anti-cholinergic drugs and H2 receptor antago-nists). There are 834 cases (90.85%) of type 3 PIM,which should be used carefully and 45 cases(4.90%) of type 4 PIM.45 cases (4.90%) of non-anti-infective drugs should be avoid or reduced as much as possible in consideration of renal function. The number of combined drug use(OR=5.331,95% CI:3.549-8.009),the age(OR=1.171,95% CI:1.093-1.249),the Chalson's comorbidity index (OR=1.964,95% CI:1.477-2.450) are risk factors of PIM. Conclusion The incidence of potentially inappropriate use of drugs is high among the elderly patients. Reducing the number of combined drugs is an important measure to avoid the occurrence of PIM in elderly patients.

Pancreatic cancer is a highly malignant tumor with a poor prognosis. It is very hard to treat pancreatic cancers for their high heterogeneity, complex tumor microenvironment, and drug resistance. Currently, gemcitabine plus nab-paclitaxel, capecitabine and FOLFIRINOX are standard chemotherapy for resectable or advanced metastatic pancreatic cancer. Considering the limited efficacy and toxic side effects of chemotherapy, targeted and immune drugs have gradually attracted attention and made some progress. In this article, we systematically reviewed the chemotherapeutic drugs, targets and related targeted drugs, and immunotherapy drugs for pancreatic cancer.

OBJECTIVE: To study the difference of Han female adolescent bone development in Henan and Zhejiang province. METHODS: All radiography including sternal end of clavicle and six main bone joints were taken from 599 female adolescents with age between 12 to 19 in Henan and Zhejiang province. Twenty four skeletal development indexes were analyzed based on "The Grading Standards" of skeletal growth of teenagers and then the bone age were calculated using mathematical model functions. The ratios of the bone age and the chronological age were analyzed by statistical software. RESULTS: The development of Henan female adolescents' skeleton was about 0.39 years earlier than that in Zhejiang at the age of 14-15 years old. The development of Henan female adolescents' skeleton was about 0.37 years later than that in Zhejiang at the age of 15-16 years old. The development of Henan female adolescents' skeleton was about 0.38 years later than that in Zhejiang at the age of 18-19 years old. There was no statistics significance in other age group. CONCLUSION The female adolescent bone development in Henan province is faster at earlier stage and then slower than that in Zhejiang province. The results provide potential value for the forensic medicine, anthropology and clinical medicine.

Long non-coding RNA (lncRNA) refer to transcripts longer than 200 nucleotides that have a low coding potential. Autophagy,a unique life phenomenon of eukaryotic cells,removes excess or damaged organelles during cell growth and development and plays a key role in maintaining homeostasis. As a key regulator of cellular metabolism,lncRNA are involved in disease treatment by regulating autophagy. This article summarizes the role of lncRNA in the treatment of cancer,cardiovascular and cerebrovascular diseases,neurodegenerative diseases,and bacterial infections and analyzes the molecular mechanisms of lncRNA in regulating autophagy,along with prospects of its applications in other areas.

Aim To investigate the effect of microinjection of EX527, a selective SIRT1 antagonist, into the ventrolateral orbital cortex (VLO) on morphine-induced conditioned place preference (CPP), and to explore the role of CREB/BDNF in it. Methods The cannulas were implanted bilaterally in the VLO of rats by brain stereotaxis surgery, and the model of morphine-induced CPP was established. The behavioral experiment consisted of four stages:habituation (d 1), pre-test (d 2-4), conditioning training (d 5-14) and test (d 15). At the stage of conditioning training, EX527 (1 μL, 5 g·L

Objective: To establish a method for the induction of peripheral blood mononuclear cells to hepatocyte-like cells, and preliminarily investigate cell response to injury under the effect of acetaminophen (APAP). Methods: The surface marker CD45 of peripheral blood mononuclear cells wase detected cells by using flow cytometry and immunofluorescence methods. The cellular morphology of induced hepatocyte-like cells was observed under an inverted microscope. Real-time fluorescent quantitative PCR (RT-PCR) was used to detect the expression level of hepatocyte-specific genes, such as cytochrome (CY) P1A2, CYP3A4, CYP2C9, albumin (ALB), alpha-fetoprotein (AFP), and hepatocyte nuclear factor (HNF)4α mRNA. Immunofluorescence method was used to detect intracellular hepatocyte markers AFP, HNF4α, and ALB expression at the protein level. Biochemical analyzer was used to detect hepatocyte-specific secretory functions of AFP, ALB, and urea. Luciferase chemiluminescence method was used to detect the activity of key drug metabolizing enzyme CYP3A4. Colorimetric assay was used to detect the effect of the drug acetaminophen on hepatocyte-like cells, and alanine aminotransferase (ALT) was used as an indicator of liver cell injury. The statistical differences between the data were compared with t-test and rank-sum test. Results: The positive expression rate of CD45 cell surface markers isolated from peripheral blood mononuclear cells was about 98%, and hepatocyte-like cell morphology changes appeared on 15th day of induction. Compared with isolated mononuclear cells, CYP1A2, CYP3A4, CYP2C9, ALB, AFP and HNF4α mRNA was markedly elevated. The expression level of AFP, ALB and HNF4α protein were equally increased, and the secretory function of AFP, ALB and urea were enhanced. Compared with primary hepatocytes, CYP1A2, CYP2C9, AFP, HNF4α mRNA, and CYP3A4 mRNA did not decrease. The expression levels of AFP, ALB, and HNF4α proteins in the cells did not decrease, and the secretory function of AFP, ALB, and urea did not decrease. In addition, the CYP3A4 enzyme activity produced by hepatocyte-like cells was similar to that of primary hepatocytes. Compared with hepatocyte-like cells incubated without APAP, hepatocyte-like cells incubated with APAP had higher ALT level. Under the effect of APAP, the ALT level of hepatocyte-like cells was higher than isolated mononuclear cells. Conclusion: Peripheral blood mononuclear cells can be induced into hepatocyte-like cells with partial characteristics of hepatocytes, including the activity of CYP3A4, a key enzyme of hepatocyte drug metabolism. Additionally, preliminarily ALT secretory features reflect the hepatocytes injury under the effect of acetaminophen.
