OBJECTIVETo study the risks on acute cerebral stroke (ACS) inducing systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS).

METHODSData from 1751 patients with acute cerebral stroke were studied by prospective analysis.

RESULTSIn all of the ACS patients,the incidence rate (IR) of SIRS was 36.50% with 205 patients having ACS inducing MODS, to which the IR was 11.71%, and 93 deaths. The case fatality ratio (CFR) was 45.37%. The pathogeneses condition of patients and the MR after the occurrence of MODS had positive correlation with the numbers of dysfunction organs. Study on single factor analysis revealed that the incidence of MODS had some related risk factors in the ACS inducing MODS, including age, diseased region close to the mean line, GCS, level of blood sugar, blood white cell count and the chronic disease history etc. The IR of ACS inducing SIRS and MODS was much higher in the condition of the diseased region near the mean line and the ACS of the basilar artery system.

CONCLUSIONSIRS seemed the base for MODS while the probability and the development degree were not only involved ACS but also SIRS. MODS induced by ACS could be reduced through the second grade program of disease precaution. The detection of those risk factors in the early period of the ACS course could provide some prediction of the prognosis and turnover, thus some early use of intervention methods might be helpful in the treatment of the disease.

BACKGROUNDEndovascular therapy is a treatment option for localized occlusion of the subclavian artery. In this report the long-term experience with 59 patients is presented.

METHODSBetween June 1998 and September 2008, we used endovascular therapy to treat 61 subclavian arterial obstructive lesions in 59 patients (46 males and 13 females, 34 - 82 years of age with a mean age (61.9 + or - 11.0) years). Twenty patients (34%) had clinical symptoms due to vertebrobasilar insufficiency, 26 (44%) had disabling arm ischemia, and 13 (22%) had both symptoms. We performed all procedures under local anesthesia. The approaches were from the femoral artery (n = 47), brachial artery (n = 1, involving bilateral subclavian disease) or both (n = 11). Sixty stents were implanted. All patients were followed-up at 1, 3, 6, and 12 months post-procedure, and annually thereafter.

RESULTSWe achieved technical success in 58 (95.1%) arteries, all of which were stented. There were three technical failures; two were due to the inability to cross over an occlusion, necessitating the switch to an axillo-axillary bypass, and the third was due to shock after digital subtraction angiography and prior to stenting. Arterial stenosis pre- and post-stenting was (83.6 + or - 10.8)% and (2.5 + or - 12.5)% (P < 0.01). Clinical success was achieved in 55 of the 59 patients (93.4%). Of the four clinical failures, three were technical and the remaining patient had a stent thrombosis. Systolic blood pressure difference between the two brachial arteries was (44.7 + or - 18.5) vs. (2.2 + or - 3.9) mmHg (P < 0.01). Primary patency was 98% at 12 months, 93% at 24 months, and 82% at 5 years. Five patients were lost to follow-up by 12 months post-stenting. Significant recurrent obstruction developed in five patients with resumption of clinical symptoms. The overall survival rate was 98.2% at 12 months, 89.5% at 24 months, and 84.5% at 5 years.

CONCLUSIONSEndovascular therapy for proximal subclavian arterial obstructive lesions is effective and successful. This minimally invasive treatment may be the first choice of treatment for proximal subclavical arterial obstructive lesions.

OBJECTIVETo evaluate the safety and efficacy of endovascular therapy for renal artery stenosis.

METHODSPercutaneous transluminal renal angioplasty with stent (PTRAS) was performed on 33 consecutive patients with severe renal artery stenosis who suffered from poorly controlled hypertension or renal dysfunction. They were subsequently underwent 7 to 49 months clinical follow up for the effect of the procedure on renal function, blood pressure control, mortality.

RESULTSAngiographic success was obtained in 32 (97.0%) of the 33 patients. The mortality was 18.2%. After PTRAS, two (6.1%) died of myocardial infarction within 4 months. Four (12.1%) patients with preoperative serum creatinine (Scr) > or = 177 micromol/L died of uraemia within 17 approximately 28 months. Twelve and twenty-four months after the procedure, systolic and diastolic blood pressure of 26 (78.8%) cases with preoperative Scr < 177 micromol/L significantly decreased (P < 0.05), with less antihypertensive medications taken and satisfactory renal function.

CONCLUSIONFor patients without serious cardiorenal disease, PTRAS has a beneficial effect on blood pressure and renal function. For patients with serious cardiorenal disease or preoperative Scr > or = 177 micromol/L, the mortality is higher. PTRAS should be performed prudently. The preservation of renal function may be enhance by using renal protection device.

OBJECTIVETo investigate the effect of endovascular therapy and artery bypass for subclavian artery occlusion disease and to explore a suitable therapeutic procedure.

METHODSThirty-nine patients with subclavian artery occlusive disease received endovascular therapy or arterial bypass from June 1997 to May 2004. Twenty-seven endovascular stenting were performed on 26 patients through the femoral artery (n = 14) or combined brachial artery (n = 12). Retrograde endovascular balloon angioplasty and stent placement were performed on 12 patients. Eight subclavian arteries were punctured with ultrasound localization. On account of unsuccessful stenting, 13 cases received arterial bypass. In addition, endovascular stenting were performed on 9 cases with carotid or vertebrarterial stenoses.

RESULTSThe blood pressure difference was less than 10 mm Hg between the treated and the healthy arms in all 39 patients. The ratio of healthy/diseased side of the mean blood pressure index increased from 0.62 +/- 0.11 preoperatively to 0.98 +/- 0.04 postoperatively (P < 0.01). The mean patency time for endovascular therapy and arterial bypass was (57.6 +/- 3.7) and (60.2 +/- 7.2) months, respectively.

CONCLUSIONSBoth endovascular therapy and arterial bypass have good curative effect for subclavian artery occlusion. Endovascular therapy is the preferred treatment for subclavian artery occlusion with mini-trauma and safety.

Schistosomiasis was once heavily endemic in Jiangsu Province. Following the control efforts for several decades, schistosomiasis was almost eradicated in all endemic counties in Jiangsu Province in 1980, and transmission control was achieved in the province in 2011. According to the principle of “implementing the control measures with adaptation to local circumstances and guiding the control programs with classified interventions”, an integrated strategy with emphasis on the management of both infectious sources and snails has been recently employed for schitsosomiasis control in Jiangsu Province. In addition, a sensitive and highly effective surveillance system has been built and the application of novel techniques and information construction has been intensified to effectively interrupt the transmission of schistosomiasis in the Province. Transmission interruption of schistosomiasis was achieved in all endemic counties in Jiangsu Province. The paper summarizes the endemic situation of schistosomiasis, progress of schistosomiasis control, and major schistosomiasis control measures implemented during the stage of transmission interruption in Jiangsu Province.

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R² of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.
