Objective To evaluate the diagnosis and treatment procedures for malignant pheochromocytoma. Methods 12 cases of malignant pheochromocytoma surgically treated were reviewed.This series comprised of 4 male and 8 female patients.All the tumors were confirmed on surgery and pathological studies. Results All the cases were operated.One died of hypotension after surgery.11 cases have been followed up for 2.5～13.0 years.4 died of recurrence and complication of hypertension.3 died of extensive metastases more then one year after operation.One died of pulmonary infection 4 years after operation and the others have been surviving. Conclusions Imaging procedures are important for the diagnosis of malignant pheochromocytoma.Recurrent tumors greater than 5 cm in diameter and uneven density in the tumor denote malignancy.Prompt radical extirpation of the tumor is the only means to achieve a long survival.

OBJECTIVE To investigate the antimicrobial-resistant profile of aminoglycosides-resistant Klebsiella pneumoniae isolated from Wenzhou.METHODS Between Jan 2006 and Sep 2007,non-replicate clinical isolates of K.pneumoniae were consecutively collected from inpatients in a teaching hospital in Wenzhou,China.Antibiotic susceptibility test was determined by the disc diffusion method recommended by CLSI.Sixty-four gentamicin-resistant isolates were investigated for the presence of ESBLs by the CLSI-recommended confirmatory tests.RESULTS Of the 64 gentamicin-resistant isolates,the resistant rates to ciprofloxacin,levofloxacin cefoxitin,tetracycline,trimethoprim/sulfamethoxazole,ceftazidime and cefotaxime were 7.5%,29.7%,39.1%,85.9%,76.6%,67.2%,and 73.4%,respectively.All isolates were susceptible to imipenem.73.4% of gentamicin-resistant isolates produced ESBLs.CONCLUSIONS Gentamicin-resistant K.pneumoniae is multi-resistant to antibiotics.

Objective To investigate the feasibility and safety of modified percutaneous left atrial appendage occlusion (PLAAO) under transthoracic echocardiographic (TTE) guidance without general anesthesia instead of transesophageal echocardiographic guidance.Methods A total of 14 patients who met the inclusion criteria underwent modified PLAAO guided by TTE instead of TEE without general anesthesia.Regular clinical follow-up observations of PLAAO-related major adverse events were done in the perioperative period.Results All patients were successfully implanted with left atrial appendage occluder device (Watchman) without device-related serious complications.Immediately occlusion success rate was 100％.No major adverse events occurred during hospitalization and follow-up.The mean operation time was 108 ± 22 min(range 75-150 min)and the mean radiation exposure time was 15.8 ± 7.6 min(range 8-32 min).Conclusion Modified PLAAO guided by TTE instead of TEE without general anesthesia may be safe and effective.This method simplifies the operation process and is favorable for PLAAO application.But this modified PLAAO is still needed to be validated in more patients.

Objective To evaluate the significance of contrast medium (CM) volume and estimated glomerular filtration rate (CM/eGFR) in predicting contrast-induced nephropathy (CIN) after PCI. Methods A total of 307 patients after PCI were enrolled from Nanfang Hospital from May 2014 to October 2015. The patients were divided into the CIN group(n = 29) and the non-CIN group(n = 278) according to whether CIN within 72 hours after PCI. The baseline renal function was assessed by the sCr and CyC, respectively. Results Twenty-nine patients (9.4%, 29/307) developed CIN. There were significant differences in Age, CM、NTpro-BNP、IABP、 Periprocedural Hypotension、Preprocedural sCr/CyC between two groups (P < 0.05, respectively). The result of multivariate logistic regression analysis showed that Age, Cardiac function ≥Ⅲ level, IABP, use CCB, CM/eGFRMDRD, CM/eGFRCyC were independent risk predictors for CIN, respectively. Receiver Operating Characteristic (ROC) curve analysis showed that the area under the curve of CM/eGFRMDRD(AUC = 0.838) was superior to CM/eGFRCyC (AUC = 0.805) without significant difference. The sensitivity and specificity were 79.3%and 76.3%(Cut-off Point = 2.094), respectively. Conclusion Both the CM/eGFRMDRD and CM/eGFRCyC may be good methods to determine maximum CM before PCI and to predict CIN after PCI currently, without significant differences between these two predictors.

Objective To assess the causal relationship between coffee intake and prostate cancer risk by using the two-sample Mendel randomization (MR) method. Methods The genome-wide association study (GWAS) data on coffee intake (exposure) and prostate cancer (outcome) were obtained from two independent data sets in UK Biobank. The inverse variance weighted method (IVW), weighted median estimator method (WME), and MR-Egger method were used for MR analyses. The OR value and 95%CI were used to represent the association between coffee intake and prostate cancer. In addition, the MR-Egger method was performed for pleiotropic and heterogeneity tests, and the leave-one-out method was used for sensitivity analysis. Results A total of 38 SNP were selected as instrumental variables. The IVW method showed that coffee intake might reduce the risk of prostate cancer (OR=0.994; 95%CI: 0.990-0.999; P=0.009). The WME method obtained the same conclusions (OR=0.991; 95%CI: 0.985-0.999; P=0.018), but MR-Egger regression did not find a causal relationship between coffee intake and prostate cancer (OR=0.992; 95%CI: 0.983-1.000; P=0.084). The MR-Egger method showed no pleiotropy (intercept=4.2E-5; P=0.581) or heterogeneity (Q=27.20; P=0.854) among the instrumental variables. The sensitivity analysis indicated that the conclusion was robust. Conclusion Two-sample Mendel randomization analysis reveals that coffee consumption might reduce the risk of prostate cancer.

Objective To evaluate the imaging methods for cardiovascular malformations in Williams syndrome(WS).Methods Thirteen cases of WS(7 males and 6 females)aged 10 months to 13 years were involved in this study.All patients underwent chest X-ray radiography,electrocardiography.echocardiography and physical examination.3 cases underwent electronic beam computed tomography (EBCT),cardiac catheterization and angiography were performed in 8 cases.Results Twelve patients were referred to our hespital for cardiac murmur and 1 cnse for cyanosis after birth.7 patients were found with "elfin-like"facial features.6 patients with pulmonary arterial stenosis.2 Cases with patent ductus arteriosus.2 case8 with 8evere pulmonary hypertension and 1 case with total endocardial cushion defect.Sudden death occurred in 2 patients during and after catlleterization.respectively. Conclusions Conventional angiography is the golden standard for the diagnosis of cardiovascular malformations in WS.Noninvnsive methods such as MSCT and MRI should be suggested because of the risk of sudden death in conventional angiography.

OBJECTIVETo summarize the features of clinical manifestations, laboratory tests and imaging findings of patients with cardiac amyloidosis (CA).

METHODSA total of 60 CA patients (including 41 male and 19 female patients) from 4 centers admitted between May, 2012 and November, 2013 were included in the study. The demographic data, medical history, clinical manifestations, laboratory test data, ECG, cardiac ultrasound, and cardiac magnetic resonance (CMR) imaging of the patients were analyzed.

RESULTSTwo-thirds of the 60 CA patients, were middle-aged or elderly men, and 47% of the patients had AL-CA. The clinical manifestations included exertional dyspnea (73%), pedal edema (47%), hypotension (47%), and hypertrophy of the tongue (22%); abnormal laboratory test results included albuminuria (53%) and liver (15%) and kidney (28%) dysfunction; blood routine, urine and serum immunoglobulin quantification and immunofixation electrophoresis could help the screening of AL-CA. Kidney (53%) and liver (15%) involvement was common, and 86% of AL-CA patients had kidney involvement. Typical ECG characteristics included poor R wave progression (35%), low voltage in limb leads (33%), and a pseudo infarct Q wave (30%); the latter two were more frequent in AL-CA. The characteristics of ultrasound findings included left ventricle thickening (100%), left atrial enlargement (87%) and enhanced echo of the myocardial granules(92%), and diastolic dysfunction was obvious in all the CA patients regardless of the systolic function. The DT and E/e' of the mitral annulus could be used as an index to evaluate diastolic dysfunction in early stage of the disease. Left ventricular (LV) global subendocardial late gadolinium enhancement (LGE, 81%) accompanied by right ventricular (RV) and atrial LGE was the typical characteristic of CMR, and the range of LGE in the RV and the two atria was wider in AL-CA than in non-AL-CA. NT-proBNP (97%) and cardiac troponin (53%) in CA patients were both elevated, which helped in diagnosing and assessing the severity of cardiac involvement, according to which 50% of the patients were found to be at a high risk, 43% at an intermediate risk, and 7% at a low risk.

CONCLUSIONThe combination of the features of clinical, laboratory tests and imaging findings of CA have important diagnostic and prognostic value for CA.

Objective:To investigate the association between hepatic echinococcus granulosus infection and necrosis with gene polymorphism of interleukin-10 (IL-10) and tumor necrosis factor-α (TNF-α), and to identify the related factors at the gene level.Methods:A total of 106 patients with hepatic echinococcosis who underwent surgical treatment in the department of hepatobiliary surgery, People′s Hospital of Xinjiang Uygur Autonomous Region from January 2018 to December 2020 were selected. Patients with necrosis caused by hepatic echinococcus granulosus infection were selected as the observation group, and patients without necrosis caused by hepatic echinococcus granulosus infection were selected as the control group, with 53 cases in each group. The serum levels of IL-10 and TNF-α were detected by enzyme-linked immunosorbent assay (ELISA). The polymorphisms of IL-10 (-592, -1082) and TNF-α (rsl800630) were detected by polymerase chain reaction (PCR). The levels of IL-10 and TNF-α and their gene polymorphisms were analyzed.Results:The levels of serum IL-10 and TNF-α in the observation group were significantly higher than those in the control group (all P<0.05); There was significant difference in genotype and allele frequency of IL-10 (-592, -1082) and TNF-α (rsl800630) (all P<0.05). The serum IL-10 level of CC genotype patients with IL-10 gene -592C/A locus in the observation group was higher than that of CA+ AA genotype patients, with statistically significant difference ( P<0.05). The serum IL-10 level in patients with TT genotype at -1082T>A of IL-10 gene in the observation group was higher than that in patients with TA+ AA genotype, with statistically significant difference ( P<0.05). The serum TNF-α level in patients with CC genotype at rsl800630C/A locus of TNF-α gene in the observation group was higher than that in patients with CA+ AA genotype, with statistically significant difference ( P<0.05). Conclusions:The changes of IL-10 (-592, -1082) and TNF-α (rsl800630) gene polymorphisms may be associated with hepatic echinococcus granulosus infection and necrosis.
