Objective:To explore the clinical characteristics, treatment and prognosis of primary cardiac tumors in infants and children.Methods:The clinical information for 21 patients with primary cardiac tumor in the Department of Pediatric Cardiology, Beijing Anzhen Hospital Affiliated to Capital Medical University from May 2010 to August 2018 were analyzed retrospectively.Their median age was 7 months (gestational age 26 weeks-15 years old, and 6 cases were found in fetal phase) and 10 cases of them were male, 11 cases were girl.The clinical features, treatment methods and prognosis were summarized.Results:Among the 21 patients, 8 cases had an atypical heart murmur, 2 cases with chest tightness and chest pain, 2 cases with congestive heart failure, 1 case with dizziness and amaurosis, 1 case with cerebral artery embolism, 1 case with higher inflammatory index, and 9 cases were asymptomatic.Totally, 13 cases underwent surgical resection.All of them were confirmed as benign tumors, including 4 cases of rhabdomyoma, 3 cases of myxoma, 3 cases of fibroma and 2 cases of inflammatory myofibroblastic tumor (IMT) and 1 case of teratomas.There was no death during perioperative period.Follow-ups were performed from 3 months to 7 years, and 3 cases had recu-rrence (2 cases with myxomas and 1 cases with IMT). There were 8 cases without treatment, of which 7 cases were clinically diagnosed as transverse leiomyoma.During the follow-up, 3 cases disappeared, 1 case became small, 2 cases had no obvious change, and 1 case was lost to follow-up.One case was considered to be malignant tumor, and died within half a year.Conclusions:Primary cardiac tumors in children are mostly benign, especially transverse leiomyoma, and their clinical manifestations are diverse.Pathological examination is the golden standard for diagnosis.Surgical treatment is a radical method for most cardiac tumors, some benign tumors can be treated with drug adjuvant therapy, while the prognosis is poor for malignant cardiac tumor patients.

OBJECTIVETo investigate the drug resistance of imipenem-resistant (IR) Gram-negative bacilli (GNB) in coal workers' pneumoconiosis (CWP)-chronic obstructive pulmonary disease (COPD) patients with lower respiratory tract infection (LRTI) and to provide a basis for clinical treatment.
METHODSSixty-six strains of IR-GNB were isolated from the sputum of CWP-COPD patients with LRTI, and the bacterial spectrum was investigated. The drug resistance of bacterial strains was studied by KB disk diffusion method.
RESULTSAmong the 66 strains of IR-GNB, 29 (43.9%) were Pseudomonas aeruginosa, 17 (25.8%) were Acinetobacter baumannii, and 11 (16.7%) were Stenotrophomonas maltophilia. The drug sensitivity test showed that all bacteria had high drug resistance; Pseudomonas aeruginosa had a susceptibility rate higher than 50% to ciprofloxacin, polymyxin B, fosfomycin, and amikacin, Acinetobacter baumannii had a susceptibility rate higher than 55% to fosfomycin, polymyxin B, and cefoperazone/sulbactam, Stenotrophomonas maltophilia had a susceptibility rate higher than 50% to cotrimoxazole, ciprofloxacin, piperacillin/tazobactam, levofloxacin, polymyxin B, and cefoperazone/sulbactam, and Pseudomonas cepacia had a susceptibility rate higher than 50% to piperacillin/tazobactam, ciprofloxacin, cefoperazone/sulbactam, and polymyxin B.
CONCLUSIONThe main species of IR-GNB are such non-fermentative bacteria as Pseudomonas aeruginosa, Acinetobacter baumannii, and Stenotrophomonas maltophilia in CWP-COPD patients with LRTI. These bacteria have high drug resistance and are sensitive to only a limited range of antibiotics.

OBJECTIVETo investigate the value of in vivo proton magnetic resonance spectroscopy (MRS) in the assessment of hepatocellular carcinoma (HCC) and monitor its metabolic change shortly after transcatheter arterial chemoembolization (TACE).
METHODSIn this prospective study, 28 consecutive patients with large HCC (> or = 3 cm in diameter) confirmed by fine needle aspiration biopsy were recruited. The 1H MRS of all hepatic lesions and some uninvolved liver parenchyma were performed with 1. 5T whole body MR scanner. Among them, 15 cases were evaluated again about one week after TACE. The main metabolites such as choline and lipid before and after interventional therapy were measured to assess the early response of the tumor.
RESULTSThe technical success rate of 1H MRS in liver was high (33/41, 80%), closely related to breath motion, location of lesion, and size of voxel. In spectra, the choline compound peak of HCC elevated compared with uninvolved liver parenchyma. After TACE, both the amplitude and the area of choline resonance peak significantly descended (choline-to-lipid ratios from 0.352 +/- 0.080 to 0.167 +/- 0.030, P = 0.026; from 0.205 +/- 0.060 to 0.070 +/-0.020, P = 0.042, respectively); yet lipid resonance peak ascended.
CONCLUSIONSIn vivo 1H MRS is technically feasible for the evaluation of large focal hepatic lesions, however, the reproducibility and stability are not as good as routine MR scan. 1H MRS can monitor the early stage metabolic changes of HCC after TACE but limitation like quantification still exists.

OBJECTIVETo evaluate the therapeutic effect of combined CT-guided percutaneous radio-frequency ablation (RFA) plus percutaneous ethanol injection (PEI) on nonresectable priminary hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE).
METHODSOne hundred fifty patients diagnosed as HCC either by pathology or by AFP combined with typical CT and angiographic image findings were studied, 99 men and 51 women, with an average of 51 years. Each patient had at least 3 lesions, ranging from 3.1 to 7.9 cm in diameter, average 5.0 cm. All patients were randomly divided into group A (control group) and group B (combination group) according to their check-in date (odd or even). In group A, 74 patients were treated with RFA alone two weeks after TACE. In group B, 76 patients were treated with RFA plus PEI two weeks after TACE.
RESULTSThe complete necrosis rate was 75.8% in group A and 89.5% in group B (P < 0.05).
CONCLUSIONThe clinical therapeutic effect of radiofrequency ablation (RFA) combined with percutaneous ethanol injection (PEI) is better than that of RFA alone after TACE in HCC.

OBJECTIVETo evaluate the clinical outcome of percutaneous endoscopic lumbar discectomy with target foraminoplasty in treating migrated lumbar disc herniation.
METHODSFrom June 2015 to January 2016, 25 patients with migrated lumbar disc herniation were treated with percutaneous endoscopic lumbar discectomy with target foraminoplasty. A total of 14 males and 11 females, aging from 23 to 52 years old (average: 37.6) were enrolled in this study. Discectomy occurred in L₂,₃ of 1 case, L₃,₄ of 3 cases, L₄,₅ of 12 cases, L₅S₁ of 9 cases. Preoperative, 1-week and 1-year postoperative visual analogue scale (VAS) scores were collected to evaluate lower back and leg pain; Oswestry Disability Index(ODI) was used to assess the lumbar function.
RESULTSAll the patients were followed up for 12 to 19 months with an average of 15.2 months. The mean operation time was 108.6 min. No injury of dura, nerve root, or wound infection were found. Preoperative, 1-week and 1-year postoperative visual analogue scale(VAS) scores of lower back pain were 5.8±0.5, 2.5±0.4, 0.9±0.2, respectively, with significant differences among each other(<0.05);VAS scores of leg pain were 7.1±0.6, 1.5±0.4, 0.7±0.6, respectively, with significant differences among each other(<0.05). Lumbar ODI scores were 69.2±1.8, 22.5±4.7, 10.2±2.4 at the above time points and showed significant differences among each other(<0.05).
CONCLUSIONSPercutaneous endoscopic lumbar discectomy with target foraminoplasty for migrated lumbar disc herniation showed advantages of less injuries, bleeding and complication. It also promotes rapid recovery, being curative safely and effectively.

Reference was made, respectively, to the national standards Determination of total α radioactivity concentration in water thick source method (EJ/T 1075-1998), Determination of total β radioactivity in water evaporation method (EJ/T 900-1994), Radiochemical analysis method of strontium-90 in water and biological samples ash (HJ 815-2016), radiochemical analysis of cesium-137 in the ash of water and biological samples (HJ 816-2016), Analysis and determination of radium-226 in water (GB 11214-1989), Analysis of trace uranium in environmental samples -3 laser fluorescence law (HJ 840-2017), and Food safety in the test of radioactive substances in food determination of natural thorium and uranium (GB 14883.7-2016). Results:The activity concentration ranges from 0.011 to 0.076 Bq/L for total alpha, 0.027 to 0.098 Bq/L for total beta, 0.21 to 0.45 mBq/L for 137Cs, 1.0 to 2.4 mBq/L for 90Sr, 6.1 to 16.0 mBq/L for 226Ra, 0.06 to 0.21 μg/L for Th, and 0.73 to 3.30 μg/L for U. There were no significant differences in the concentrations of total alpha, total beta, 90Sr, 137Cs, 226Ra, U and Th in different water sources and different years ( P>0.05). There were no significant differences in the concentrations of total alpha, total beta, 90Sr, 137Cs and 226Ra during different water periods ( P>0.05). There were statistical differences in U activity concentration in different water periods ( H=16.53, P<0.05), and statistical differences in Th activity concentration in different water periods ( H=15.61, P<0.05). Conclusions:The survey showed that the total alpha, total beta, 90Sr, 137Cs, 226Ra, U and Th radioactivity levels in drinking water sources in Chengdu, Yibin, Mianyang, Guangyuan and Leshan of Sichuan province were at the same level as the relevant data in the Natural environmental radioactivity level in China published by the State Environmental Protection Bureau in 1995. All of there values were within the data range released by the 2013-2021 National Radiation Environment Monitoring Quality Report issued by the Radiation Environment Monitoring Technology Center of the Ministry of Ecology and Environment. The radioactivity level in water sources in the five key cities was at a safe level.

OBJECTIVETo investigate the association between birth defects and dietary nutrient intake in a high risk area of China.
METHODSA dietary survey was performed and serum folic acid was measured in women whose pregnancy was affected by neural tube defects (NTDs) or unaffected by any birth defects (BDs) in Zhongyang and Jiaokou Counties in Shanxi Province of China.
RESULTSThe local average consumption of foods including dark green vegetables, fruits, fat and meat, and nutrient intake (e.g., energy, protein, retinol, riboflavin, vitamin E, and selenium) were lower than the national average level. In women of childbearing age, these regions, the intake of nutrients was much lower than the recommended nutrient intake (9%-77%). The case-control dietary nutrition study of women whose pregnancy was affected by BDs (including NTDs and congenital heart defects) demonstrated that, in early pregnancy, adequate nutrition (i.e., eating meat, fresh vegetables, fruit more than once a week) was a protective factor, while eating germinated potatoes was a risk factor. The geometrical mean (p5-p95) of serum folic acid in women with NTD birth defects was 9.6 nmol/L (3.6, 23.03), which was significantly lower than that in normal women (14.03 nmol/L).
CONCLUSIONWomen of childbearing age in the two counties of Shanxi Province, China, have a marked insufficient intake of some nutrients, especially folic acid, zinc, vitamins A and B12. This nutrient deficiency may be an important risk factor for the high prevalence of birth defects in these regions. Therefore, adequate dietary nutrition in early pregnancy can prevent BDs.
