Objective: To discuss the methods of treatment patients with aortic valve lesions associated with ascending aortic dilation. Methods: From 1996 to 2002, 32 patients were underwent Wheat procedure. The mean age of patients was (48 6?8 9) years. The pathology of aortic valve was bicuspid valve (19 cases,59%). The mean diameter of ascend aorta was (52 2?4 5) mm (45~60 mm). All patients received aortic valve and ascend aorta replacement. Results: All patients survived. The mean duration of follow up was 22 months. There was no postoperative death and no pseudoaneurysm. All patients were in NYHA class I~II after surgery. Conclusion: Wheat procedure is a simple and effective treatment for patients with ascending aorta dilation who need aortic valve replacement.

From August 2007 to January 2009 a total of 95 patients with complex renal calculi were treated with CT ( n = 32 ), X-ray ( n = 33 ) or ultrasound ( n = 30 ) guided percutaneous nephrostomy and ureteroscopic holmium laser lithotripsy respectively. The CT guided procedure had lower positioning time,positioning failure rate, complication rate and residual stone rate than those of X-ray and ultrasound localization, particularly had advantages in the stone clearance rate and complications rate ( all P < 0. 05 ).CT guided localization can be chosen in the following conditions: higher kidney position, large staghorn calculi or renal pelvis stones without hydronephrosis, with congenital renal malformations or failure of ultrasound or X-ray localization.

Objective To evaluate the expression levels of peptidylarginine deiminase 4 (PADI4)and B-cells pecific Moloney leukemia virus insert site-1 (BMI-1 )in esophageal squamous cell carcinoma (ESCC) tissues and pericarcinous tissues.To explore the function and clinical significance in the development of ESCC and their association.Methods The expression levels of PADI4 and BMI-1 were measured by immunohisto-chemistry,Western blotting and quantitative real time PCR in ESCC tissues and pericarcinous tissues from 86 patients.The relationships between the expressions of PADI4 and BMI-1 and the clinicopathologic characte-ristics were analyzed.Results The immunohistochemistry showed that the expressions of PADI4 and BMI-1 in ESCC tissues (68.6% and 73.3%)were significantly higher than those in pericarcinous tissues (37.2% and 30.2%,χ2 =1 7.01 1 ,P =0.000;χ2 =31 .876,P =0.000).Western blotting indicated that the levels of PADI4 and BMI-1 were higher than those in pericarcinous tissues (0.91 9 ±0.098 vs.0.71 8 ±0.1 03,t =2.462,P =0.021 ;0.975 ±0.074 vs.0.71 7 ±0.071 ,t =2.640,P =0.01 4).The expressions of BMI-1 and PADI4 mRNA in ESCC tissues were higher than those in pericarcinous tissues,but the differences were not sta-tistically significant (0.091 ±0.005 vs.0.038 ±0.002,t =1 .701 ,P =0.1 01 ;0.1 1 4 ±0.075 vs.0.048 ± 0.003,t =1 .499,P =0.1 46)by the quantitative real time PCR.The expression of PADI4 was correlated with lymph node metastasis (χ2 =5.771 ,P =0.01 6),depth of invasion (χ2 =6.672,P =0.01 0)and clinical stage (χ2 =5.771 ,P =0.01 6).The BMI-1 gene expression had a correlation with lymph node metastasis (χ2 =7.1 76,P =0.007),the differentiation degree (χ2 =1 3.787,P =0.001 )and clinical stage (χ2 =7.1 76,P =0.007).In addition,there was a positive correlation between PADI4 and BMI-1 expression in ESCC by immunohistochemistry and quantitative real time PCR (r =0.21 4,P =0.047;r =0.534,P =0.005).Conclusion The expression levels of PADI4 and BMI-1 are significantly higher in ESCC compared to pericarcinous tissues.PADI4 and BMI-1 are positively correlated and may contribute to the diagnosis and prog-nosis of the ESCC.

Endogenously eliminating the hematoma is a favorable strategy in addressing intracerebral hemorrhage (ICH). This study sought to determine the role of retinoid X receptor-α (RXR-α) in the context of hematoma absorption after ICH. Our results showed that pharmacologically activating RXR-α with bexarotene significantly accelerated hematoma clearance and alleviated neurological dysfunction after ICH. RXR-α was expressed in microglia/macrophages, neurons, and astrocytes. Mechanistically, bexarotene promoted the nuclear translocation of RXR-α and PPAR-γ, as well as reducing neuroinflammation by modulating microglia/macrophage reprograming from the M1 into the M2 phenotype. Furthermore, all the beneficial effects of RXR-α in ICH were reversed by the PPAR-γ inhibitor GW9662. In conclusion, the pharmacological activation of RXR-α confers robust neuroprotection against ICH by accelerating hematoma clearance and repolarizing microglia/macrophages towards the M2 phenotype through PPAR-γ-related mechanisms. Our data support the notion that RXR-α might be a promising therapeutic target for ICH.

Polymyxin B, which is a last-line antibiotic for extensively drug-resistant Gram-negative bacterial infections, became available in China in Dec. 2017. As dose adjustments are based solely on clinical experience of risk toxicity, treatment failure, and emergence of resistance, there is an urgent clinical need to perform therapeutic drug monitoring (TDM) to optimize the use of polymyxin B. It is thus necessary to standardize operating procedures to ensure the accuracy of TDM and provide evidence for their rational use. We report a consensus on TDM guidelines for polymyxin B, as endorsed by the Infection and Chemotherapy Committee of the Shanghai Medical Association and the Therapeutic Drug Monitoring Committee of the Chinese Pharmacological Society. The consensus panel was composed of clinicians, pharmacists, and microbiologists from different provinces in China and Australia who made recommendations regarding target concentrations, sample collection, reporting, and explanation of TDM results. The guidelines provide the first-ever consensus on conducting TDM of polymyxin B, and are intended to guide optimal clinical use.
