Study the serum level of HGF, Cys C and TGF-beta1 in type 2 diabetic nephropathy (DN), the infect of Pingshen decoction on those index. Selected 69 cases of 2 type DN and randomly divided into therapy group (36 cases) and control group (33 cases). The therapy group were treated with Pingshen decoction 1 dose/d, bid po. The control group were treated with NephritisShu tablet, 6 tablet, tid po. 8 weeks was a course. Before and after treatment, we examine the serum level of HGF, Cys C and TGF-beta1 by ELISA and immunonephelometry, and compare with 30 cases of healthy control group. The study demonstrates that before treatment, the serum level of HGF in both groups were significantly lower than healthy control group (P < 0.01), but Cys C, TGF-beta1 were significantly higher (P < 0.01). After treatment, the serum level of HGF of both groups were increased. The serum level of HGF of therapy group were significantly higher than of control group (P < 0.01), but the serum level of Cys C and TGF-beta1 were significantly lower than control group (P < 0.01). The serum level of HGF was correlated negatively with Cys C,TGF-beta1. In control group, the UAER, urine beta2-MG and quantity of 24-hour urine protein were significantly decreased after treatment (P < 0.01). The index of urine of therapy group were significantly lower than control group (P < 0.01). Results indicate that test of serum level of HGF and Cys C,TGF-beta1 of diabetic nephropathy have important clinical significance. Pingshen decoction can effectively intervene in the serum level of HGF and Cys C, TGF-beta1 and index of urine.

Objective: To evaluate the quality of Pneumoconiosis Network Direct Report in Sichuan Province in 2006-2016. Methods: download all the pneumoconiosis report cards from the Network Direct Report system. Screen out cards based on the diagnosis time that is between January 1st 2006 and December 31st 2016. Using R 3.4.0 software to analysis the number of missing or repeated cards, time-logical error rates, timeliness, reporting year, reporting intervals to evaluate the quality of Pneumoconiosis Network Direct Report and location distribution. Results: there are 38 855 pieces of Pneumoconiosis report card in total in 2006-2016. 352 pieces of cards were reported twice. 224 cards were missing. 229 cards have time-logical error. The rate of timely reporting for 2006-2016 years was 66.41% (2 5453/38 326) , 67.14% (24 658/36 726) for new cases, 58.87% (783/1 330) for promoting cases and 4.44% (12/270) for deaths. 87.38% (33 490/38 326) patients was reported in the same year. 10 days was needed to finish one report, confirming-filling cost much more time than filling-report (9.865/49.019) . Conclusion the records of pneumoconiosis report cards are much more complete, logical errors are less, and the timeliness was a little bit higher than the average level in China. But it also should be improved. The death cases are difficult to report. It takes longer to diagnose and fill in cards. Improving the timeliness rate can significantly improve the quality of network direct reporting.

OBJECTIVETo analyze the clinical characteristics, image findings, laboratory examination, the therapeutic methods and clinical outcomes of bronchiolitis obliterans (BO) in pediatric patients.

METHODTwenty-six pediatric patients with BO were reported. All data were collected from cases who were hospitalized in the Department of Pediatrics, First Affiliated Hospital of Guangzhou Medical College from June 1(st), 2009 to the April 30(th), 2011, and infectious agents, clinical manifestations, risk factors, changes in imageology, laboratory examination, therapeutic methods and treatment responses were analyzed.

RESULTThe ranges of age at onset was 4.5 months-8 years in 26 cases (18 boys and 8 girls). The course of disease was (6.2 ± 3.5) months. The period of followed-up ranged from 2 to 24 months. The common clinical characteristics were persistent wheezing of different severity (26 cases, 100%), cough (24 cases, 92%), intolerance to exercise (22 cases, 85%), short of breath (21 cases, 81%), retraction (20 cases, 77%), wheezy phlegm (16 cases, 62%), keeping with crackles (10 cases, 38%), cyanosis around the mouth (3 cases, 12%) and no clubbed fingers (toes). In 18 cases the etiology was detected, mycoplasma (11 cases, 42%), respiratory syncytial virus (4 cases, 15%), parainfluenza virus (2 cases, 8%), influenza virus A (2 cases, 8%) and influenza virus B (2 cases, 8%), human bocavirus (HBoV) (1 case, 4%). There were 8 cases (31%) with combined infection. Chest X-ray in 10 cases indicated changes suggestive of bronchopneumonia (38%), in only 1 case there was an image of interstitial pneumonia disease (4%). All the patients were diagnosed by high-resolution computerized tomography (HRCT). All cases were demonstrated to have air retention, poor blood perfusion in lung, just like "Westemark sign" with HRCT. In 19 cases antineutrophil cytoplasmic antibody (ANCA) was determined and 10 patients (53%) were positive for P-ANCA, and 8 cases (42%) were positive for C-ANCA. All patients received oral corticosteroid and low doses azithromycin. In 13 cases (50%) the treatment effectively reduced the severity of disease and the frequency of cough and wheezing. The average number of days for symptom improvement was (7.1 ± 4.8) days.

CONCLUSIONRespiratory infection plays an important role in BO in children. The chronic and persistent wheezing, cough, intolerance to exercises, short breath, retraction were the main clinical manifestations. But these symptoms are non-specific. Chest X-ray can not provide enough information for diagnosis. Classical "Westemark sign" with HRCT is an important sign. ANCA with a high positive rate (approximately 50%) suppose immuno-lesion in BO. Oral corticosteroid and methotrexate may relieve clinical symptoms.

OBJECTIVEDiscussing the natural history and the influencing factors of HIV infection among former commercial blood and plasma donors engaged in unsafe blood donation practices in China.

METHODSUsing ambispective cohort study, with data obtained from ten counties (districts) from six provinces in the National AIDS Control Demonstration Area. HIV/AIDS cases were found and confirmed prior to July 24, 2006 being former commercial blood. Plasma donors were selected and data regarding infection, incidence, death, and influencing factors was collected. Analysis was performed using SPSS 12.0 statistical analysis software.

RESULTS(1) In 7551 cases of HIV infection, there were 6533 typical progressors (86.52%, 4757 cases of AIDS), 108 rapid progressors (1.43%), 910 long-term non-progressors (12.05%) with 4865 cases progressed to AIDS (64.43%). The median incubation period for HIV progression to AIDS was nine years (95% CI:8.96-9.04). (2) According to data, from a total of 1157 AIDS cases without ARV therapy (23.78% of total AIDS cases), there were 283 confirmed AIDS-related deaths, of which the median survival time was 6 months (95% CI:4-7) and the two and three year fatality rates were 95% and 99%, respectively. (3) The duration of HIV incubation period was irrespective to gender and age at the time of HIV infection (P > 0.05). Length of survival for untreated AIDS showed correlation to gender (P < 0.05) but no correlation with culture, marital status or age at the time of diagnosis of AIDS (P > 0.05).

CONCLUSIONCompared with the UNAIDS theory regarding slow disease progressors among adults, our study showed a longer AIDS incubation period and shorter outlook for untreated survival, but a similar incubation period for other routes of HIV infection.

Background/Aims: Accumulating evidence indicates that L-carnitine (LC) protects against multiorgan damage through its antioxidant properties and preservation of the mitochondria. Little information is available about the effects of LC on renal fibrosis. This study examined whether LC treatment would provide renoprotection in a rat model of unilateral ureteral obstruction (UUO) and in vitro. Methods: Sprague-Dawley rats that underwent UUO were treated daily with LC for 7 or 14 days. The influence of LC on renal injury caused by UUO was evaluated by histopathology, and analysis of gene expression, oxidative stress, mitochondrial function, programmed cell death, and phosphatidylinositol 3-kinase (PI3K)/ AKT/forkhead box protein O 1a (FoxO1a) signaling. In addition, H2O2-exposed human kidney cells (HK-2) were treated with LC. Results: LC treatment inhibited expression of proinflammatory and profibrotic cytokines, and was followed by a significant attenuation of tubulointerstitial inflammation and fibrosis. The increased oxidative stress caused by UUO was associated with mitochondrial dysfunction and excessive apoptosis and autophagy via PI3K/AKT/FoxO1a-dependent signaling, and this was abrogated by administration of LC. In H2O2-exposed HK-2 cells, LC decreased intracellular production of reactive oxygen species, and suppressed expression of profibrotic cytokines and reduced the number of apoptotic cells. Conclusions LC protects against the progression of tubulointerstitial fibrosis in an obstructed kidney.

BACKGROUNDErythromycin-resistant Streptococcus pneumoniae isolates that causing invasive pneumococcal diseases (IPD) in Chinese children remain uncharacterized. This study aims to identify the resistance genes associated with erythromycin resistance and to determine the genetic relationships of IPD isolates in Chinese children.

METHODSA total of 171 S. pneumoniae strains were isolated from 11 medical centers in China from 2006 to 2008. All the isolates were characterized via serotyping and antibiotic susceptibility determination. The erythromycin-resistant isolates were further characterized via ermB and mefA gene detection, multi-locus sequence typing analysis, and pulsed-field gel electrophoresis.

RESULTSA total of 164 (95.9%) isolates showed resistance to erythromycin, of which 162 strains with high high-level resistance (MIC ≥ 256 µg/ml). A total of 104 (63.4%) isolates carry the ermB gene alone, whereas 59 (36.0%) harbor both ermB and mefA genes. Of the 59 strains, 54 were of serotypes 19A and 19F and were identified as highly clonal and related to the Taiwan(19F)-14 clone.

CONCLUSIONSThe erythromycin resistance rate in IPD isolates is significantly high and is predominantly mediated by the ermB gene. Isolates that carry both ermB and mefA genes are predominantly of serotypes 19A and 19F.
