OBJECTIVETo investigate the clinical and pathologic characteristics of anti-glomerular basement membrane(GBM) disease with normal renal function.

METHODSThe clinical and pathologic data of 6 patients with anti-GBM disease and normal renal function in Peking Union Medical College Hospital were reviewed retrospectively. Furthermore, 29 patients with anti-GBM disease and impaired renal function in the same period in the same hospital were enrolled as the control group. Factors that may influence the prognosis were analyzed.

RESULTSSix (17.1%) of all 35 patients maintained normal renal function for 12-133 months during follow-up. Five patients had microhematuria and proteinuria, one had pulmonary hemorrhage only, and three manifested as Goodpasture syndrome. Renal biopsies from 4 patients revealed linear deposition of IgG 2+-3+ along the glomerular capillary walls by immunofluorescence. As shown by normal light microscopy, mild mesangial proliferation and crescentic glomerulonephritis with a large amount of fibrinoid necrosis of glomerular capillary walls were observed in different patients; however, most pathological changes were mild. Five of these six patients were treated with immunosuppressive drugs and/or plasma exchange. Compared with the control group, the 6 patients with normal renal function had significantly higher hemoglobin[(77.97±20.62 vs.(99.67±19.80 g/L P=0.024], lower titers of anti-GBM antibody[(224.34 ± 145.79 vs.(80.23 ± 85.73 EU/ml P=0.027], and lower ratio of glomeruli with crescents[(0.58±0.29 vs.(0.17±0.27 ,P=0.005]. These 6 patients with normal renal function were followed up for 12-133 months, among whom 4 patients achieved complete remission and 2 had mild proteinuria and microhematuria.

CONCLUSIONAnti-GBM disease with normal renal function is not uncommon. Most patients have mild pathologic changes and good prognosis.

OBJECTIVETo investigate the influence of lead exposure in rats during the developmental stage on the expression of leptin in plasma, cerebrospinal fluid, and hippocampus, as well as investigating whether leptin is associated with the mechanism of cognitive impairment induced by lead exposure.

METHODSThe rat model of cognitive impairment after chronic lead exposure was established by adding lead acetate into drinking water. According to the concentration of lead acetate in drinking water, the rats were divided into control (0 ppm), low-lead (50 ppm), medium-lead (200 ppm), and high-lead groups (1 000 ppm), with 16 rats in each group. Atomic absorption spectrometry was used to measure the content of lead in the plasma, cerebrospinal fluid and hippocampus. ELISA was used to measure the level of leptin in the plasma and cerebrospinal fluid. Immunohistochemistry was used to observe the distribution of leptin protein in the hippocampus. Western blot was used for relative quantification of leptin proteins in the hippocampus.

RESULTSCompared with the control group, the lead exposure groups showed significant increases in the content of lead in blood, cerebrospinal fluid, and hippocampus (P<0.01), as well as significant reductions in the levels of leptin in plasma and cerebrospinal fluid (P<0.05). The results of immunohistochemical staining showed that leptin was mainly distributed in the cytoplasm of pyramidal neurons in the hippocampal CA region. The results of Western blot showed that compared with the control group, the three lead exposure groups showed a slight increase in the protein expression of leptin in the hippocampus (P>0.05).

CONCLUSIONSLead exposure can reduce the levels of leptin in plasma and cerebrospinal fluid in rats, which may be associated with the mechanism of cognitive impairment induced by lead exposure.

OBJECTIVETo evaluate the acceptability of self-management project for patients with hypertension and the short term result, and provide the evidence of preventing and controlling hypertension using chronic disease self-management.

METHODSVoluntary patients with hypertension were grouped into the control and experimental groups after matching age, sex, education levels and the number of chronic diseases between the two groups. Data collected through questionnaire after intervention were compared with the baseline data through analysis of covariance and chi(2) test.

RESULTSRate of awareness for the diagnostic criteria of hypertension, risk factors and associated diseases increased by 56.4%, 50.4% and 37.6% respectively, and the rate of high salt diet intake, body mass index and the times of visiting doctors decreased by 27.1%, 0.8 kg/m(2) and 2.7 times on average in experimental group, as compared with control group. The health status (energy, fatigue, shortness of breathe, pain) improved (P < 0.05). In the similar comparison, the rate in which the hypertensive patients took antihypertensive medicine increased by 20%, and the scores of cognitive symptoms management and of patient communication with physician increased by 3.9 and 1.1 points respectively. The rate of compliance to medication increased by 21.5% compared with themselves.

CONCLUSIONThe awareness rate of hypertensive patients on knowledge and on unhealthy life style improved after implementing the self-management program. Their emotion, healthy behavior, health status and symptoms related to hypertension improved. Data showed that it was effective for hypertensive patients to use chronic diseases self-management.

AIM:To investigate the role of peroxisome proliferator-activated receptors(PPARs)-inflammation signaling pathways in diabetic hepatopathy.METHODS:Diabetic mouse model was established by feeding the mice with a high-energy diet for 4 weeks combined with intraperitoneal injection of streptozotocin(STZ;40 mg· kg-1· d-1for 5 d). The hepatopathy model was confirmed by histopathological observation and the indexes of liver function, such as alanine aminotransferase(ALT),aspartate aminotransferase(AST)and alkaline phosphatase(ALP),after another 4 weeks.Mo-reover,fasting blood glucose(FBG), and serum levels of total cholesterol(TC), triglyceride(TG)and insulin were measured,and the HOMA insulin resistance index(HOMA-IR)was calculated.The mRNA and protein expression levels of PPARs and inflammation-related factors were measured by qPCR and Western blot, respectively.RESULTS: After treatment with STZ for 7 d,the FBG of mice exceeded 11.1 mmol/L,suggesting that the diabetic model was established. After 4 weeks,the structural deformation of the hepatocytes(including hepatocytes containing abundant fat vacuoles, and inflammatory cell infiltration),and the increases in the serum levels of insulin,HOMA-IR,TC,TG,ALT,AST and ALP were observed(P<0.01), indicating the occurrence and progression of hepatopathy in diabetic mice.Meanwhile, com-pared with the control group,the mRNA and protein expression of PPARα,PPARβand PPARγdecreased,but the expres-sion of nuclear factor-κB(NF-κB),cyclooxygenase 2(COX-2)and inducible nitric oxide synthase(iNOS)significantly increased in the diabetic hepatopathy mice(P <0.01).CONCLUSION: Down-regulation of PPARα, PPARβand PPARγand activation of NF-κB-COX-2/iNOS signaling pathways may be involved in the diabetic hepatopathy in mice in-duced by long-term high-energy diet feeding combined with intraperitoneal injection of STZ.

To evaluate the effect of Alpinia officinarum Hance (A. officinarum) extract on lung injury caused by particulate matter (PM). Methods: The Kunming mice were intranasally instilled with PM and treated with A. officinarum extract for 3 weeks. Bronchoalveolar lavage fluid, blood and lung samples were collected for biochemical, serological and histopathological studies. Results: Serological analysis showed that albumin levels, lactate dehydrogenase and alkaline phosphatase activities in bronchoalveolar lavage fluid were significantly reduced after administrations of 50, 100 and 200 mg/kg of A. officinarum extracts to the PM injured mice. Markers of oxidative stress, nitric oxide, malondialdehyde levels and nitric oxide synthase activities, were significantly decreased. Correspondingly, total superoxide dismutase activity was improved dramatically. The expressions of interleukin-6 and tumor necrosis factor alpha were also down-regulated obviously. In addition, pathological sections of lung tissue showed that A. officinarum could reduce the infiltration of inflammatory cells, pulmonary edema and pulmonary fibrosis. These results showed that A. officinarum extract could alleviate PM-induced lung injury via reducing the permeability of cell membranes in lung tissue, eliminating oxidative stress and relieving inflammatory response. Conclusions: A. officinarum extract was an efficient treatment for PM-induced lung injury ir mice, and it may be a promising therapeutic agent in future.

OBJECTIVETo study the effect of extraneous p53 gene with deletion of c-terminal 356 - 393 amino acids on inhibition of malignant phenotype of human lung cancer cell line.

METHODSRecombinant plasmid pEGFP-p53 (del) with codon deletion of c-terminal 37 amino acids from 393 to 356 region and pEGFP-p53 (wild type) were constructed. The human lung cancer cell line 801D served as a receipt cell had p53 deletion and mutation at 248 codon. 801D cells, having been transfected by pEGFP-p53 (wild type), pEGFP-p53 (del) or pEGFP, were selected by G418. Growing transfected cells were cloned respectively by method of dilution. Presence of extraneous gene was detected by PCR, their expression in cells was examined by fluorescence microscopy. Cloning efficiency was in vitro tested to examine the cellular proliferating ability. The xenograft in nude mice was performed and xenograft tumors were weighed one month later. Expression of GFP in tumor and transplanted cellular mass were detected by blot slices.

RESULTSpEGFP-p53 (del)-801D, pEGFP-p53-801D and pEGFP-801D were established. Extraneous p53 gene and expression of GFP were found in pEGFP-p53 (del)-801D and pEGFP-p53-801D. Inhibitory rate of colony was 99.6% for pEGFP-p53 (del)-801D and 81.0% for pEGFP-p53-801D. Inhibition of malignant proliferation of extraneous p53 (del) was higher than that of p53 (wild type) (P < 0.01). Even when inhibition of malignant proliferation extraneous pEGFP-p53 (del) was obvious, 0.2% colonies were formed, extraneous p53 and expression of GFP were observed. Animal test showed that tumor on the nude mice was positive (4/4, 4/4) in the control group (801D and pEGFP-801D), but negative (0/4, 0/4) in the experiment group [pEGFP-p53 (del) 801D and pEGFP-p53 (wild type) 801D]. Expression of GFP in the cells of cellular mass transplanted by pEGFP-p53 (del) 801D or pEGFP-p53 (wild type) 801D was observed.

CONCLUSIONIn vitro inhibitory effect of extraneous p53 gene with deletion of C-terminal 356 - 393 amino acids on malignant growth of lung cancer cell with p53 mutation or deletion at 248 codon is marked. Inhibitory action of p53 on malignant proliferation of cancer cells is heterogeneous.

OBJECTIVETo explore a more optimal therapy for intractable insomnia.

METHODSSeven hundred cases of intractable insomnia that were in accordance with the criteria were randomly divided into an observation group (368 cases) and a control group (332 cases). The acupuncture prescription of regulating yin-yang and five viscera was applied in the observation group, where Dazhui (GV 14), Shenmai (BL 62), Guanyuan (CV 4), Zhaohai (KI 6), Geshu (BL 17), etc. were selected. The acupuncture prescription of tranquilizing mind was applied in the control group, where Baihui (GV 20), Sishencong (EX-HN 1), Anmian (Extra), Shenmen (HT 7), Sanyin jiao (SP 6) were selected. The treatment was given once a day, ten times of which made a session. After the treatment for 4 sessions, the clinical efficacy and Pittsburgh sleep quality index (PSQI) were compared between two groups.

RESULTSThe total effective rate was 92.6% (338/365) in the observation group, which was superior to 73.1% (242/331) in the control group (P < 0.05). The PSQI score was obviously decreased in two groups after the treatment (both P < 0.05), in which the decreasing in the observation group was superior to that in the control group (P < 0.05).

CONCLUSIONThe acupuncture prescription of regulating yin-yang and five viscera has better effect for intractable insomnia, which could be considered as a more optimal therapy.

OBJECTIVEAssess the clinical implication of microvasculopathy detected by endomyocardial biopsy samples in patients post heart transplantation.

METHODSLight microscopic evaluations were performed in 278 endomyocardial biopsies harvested from 64 patients post heart transplantation for more than one year, microvasculopathy was defined as stenotic endothelial and/or medial disease.

RESULTSThe patients with stenotic microvasculopathy were younger than those without microvasculopathy (40.7 ± 15.9 vs. 49.4 ± 8.7, P < 0.05). The mean score of acute cellular rejection (0.83 ± 0.39 vs. 0.37 ± 0.32, P < 0.01) and the numbers of ≥ grade II acute rejection (0.84 ± 0.16 vs. 0.23 ± 0.10, P < 0.01) were significantly greater in stenotic microvasculopathy group compared to those of non-stenotic group. Multivariate regression analysis confirmed that stenotic microvasculopathy is the independent risk factor for the mean acute rejection score (OR = 3.40, 95%CI, 4.62 - 193.07, P < 0.01), but not for the Quilty lesion, coronary heart disease of donor, diabetes mellitus. Angiographically confirmed coronary vasculopathy and cardiac dysfunction (χ(2) = 0.94, P > 0.05 and χ(2) = 2.90, P > 0.05) were similar between microvasculopathy group and non-microvasculopathy group.

CONCLUSIONPost heart transplantation microvasculopathy is an immune-mediated phenomenon and associated with higher mean score of acute cellular rejection and higher numbers of ≥ grade II acute rejection but was not the prognostic risk factor for coronary vasculopathy and function reduction after heart transplantation.
