Objective To evaluate the blood supply features and effectiveness of arterial chemoembolization for pedunculated hepatocellular carcinoma.Methods Angiography and chemoembolization via supplying blood arteries of tumor were performed in five patients with pedunculated hepatocellular carcinoma.Interventional procedure was carried out with tumor vascular infusion of 350 mg hot elemene emulsion and tumor embolization by cisplantin-lipidol emulsion(cisplantin 60-80 mg+lipidol 8-15 ml)and glutin.Results Ten interventional procedures(TACE)were undertaken in 5 patients.Angiography showed that tumor blood supply mainly coming from collateral circulation adjacent to the tumors,but partially from hepatic artery.Tumor sizes decreased from 30% to 50% in 5 cases,and AFP declined in 4 cases after the treatment. Conclusion Pedunculated hepatocellular carcinoma possessing different blood supply features from intrahepatocellular carcinomas.But transarterial ehemoembolization is still an effective method of choice for this treatment.

Interaction of salinity (NaCl) and cadmium (Cd) on growth, mineral nutrients, Na and Cd accumulation in four barley genotypes differing in salt tolerance was studied in a hydroponic experiment. Cd, NaCl and their combined stresses reduced Ca and Mg concentrations in roots and shoots, K concentration in shoots, increased K and Cu concentrations in roots relative to control, but had non-significant effect on micronutrients Cu, Fe and Mn concentrations in shoot. The three stresses reduced accumulation of most tested nutrients in both roots and shoots, except NaCl and NaCl+Cd stresses for root K and shoot Cu accumulation in salt tolerant genotypes. The salt tolerant genotypes did not have higher nutrient concentration and accumulation than the sensitive ones when exposed to Cd and NaCl stresses. In conclusion, the affecting mechanism of Cd stress on nutrients was to some extent different from salinity stress, and the NaCl+Cd stress was not equal to additional Cd and NaCl stresses, probably due to the different valence and competitive site of Na(+) and Cd(2+). NaCl addition in the Cd-containing medium caused remarkable reductions in both Cd concentration and accumulation, with the extent of reduction being also dependent on genotypes. The salt-tolerant genotypes had lower Na concentration than sensitive ones.

Objective: To investigate the effects of pravastatin o n atherosclerotic plaque and cardiovascular events. Methods: Fifty- seven patients with coronary artery disease (44 male and 13 female, 58.4±11.3 y ears) were randommized into pravastatin and control groups. The patients in prav astatin group were administered 10 mg of pravastatin from the night of coronary angiography day. After 7.3 months (mean) of follow-up, plasma lipid parameters and coronary angiograph were repeated. Results: (1) A favorable effect on plasma lipid parameters was found. After administration, total choles terol(TC), low density lipoprotein cholesterol (LDL-C) and triglyceride(TG) red uced by 15.0% (P<0.01), 18.0% (P<0.01) and 6.0%, respectively. High den s ity lipoprotein cholesterol(HDL-C) increased by 10.6%. However, in control grou p, TC and LDL-C showed a tendency to reduce, but no significant difference was found between those of pre- and post-administration. (2)There was no significa nt difference in luminal diameter between pre- and post-administration in both groups. (3) Cardiovascular events in pravastatin group was significantly lower than those in control (P<0.05). (4) Pravastatin had no significant effect on HR, BP and left ventricular ejection fraction in both groups. Conclusio n: Pravastatin can stabilize coronary atherosclerostic plaque and reduce the incidence of cardiovascular events by improving plasma lipid parameters.

OBJECTIVEWe observed the therapeutic effectiveness and safety of different antidepressants as well as the correlation between symptomatic improvement of depression and improvement of chest pain in patients with susceptible "angina pectoris" and negative coronary angiogram complicating comorbid depression.

METHODSIn this double-blinded randomized study, a total of 123 eligible patients were allocated into three groups: (1) Group F: fluoxetine 20 mg QN (n = 41); (2) Group P: Placebo 1 tablet QN (n = 40); (3) Group F + O: fluoxetine 20 mg + olanzapine 2.5 mg QN for the former 2 weeks and only fluoxetine 20 mg QN for the latter 2 weeks (n = 42). The total therapy duration was 4 weeks. HAMD, HAMA and self-evaluation table of chest pain were obtained before therapy, at the end of 1 and 2 weeks after therapy.

RESULTSBaseline HAMD and HAMA scores and self-evaluation score of chest pain were similar among 3 groups and all scores were significantly improved post various therapies in the order of group F + O > group F > group P. The rate of score decrease were seen after 1 week treatment in group F + O and after 2 week treatment in group F. There was a significant positive correlation between the rates of self-evaluation chest pain score decrease and HAMD (r = 0.867, P < 0.001) and HAMA (r = 0.854, P < 0.001) score decreases after 4 weeks therapies (P < 0.05). During the whole course of treatment, no serious adverse reaction was found in all patients.

CONCLUSIONIn patients with suspected "angina pectoris" and negative coronary angiogram complicating comorbid depression, the antidepressants were safe and significantly improved the symptoms of depression and anxiety and chest pain. Low dose fluoxetine plus short term olanzapine regimen was superior to fluoxetine alone regimen in terms of stronger and quicker symptom improvement.

Objective:Lung ultrasound (LUS) has been used in the diagnosis of neonatal respiratory distress syndrome(RDS) successfully, but there have been no multicenter prospective studies to verify its reliability or determine how to grade RDS with LUS findings.This study aimed to discuss the necessity and feasibility of using LUS findings to determine RDS grades through a multicenter prospective study.Methods:Every researcher participated in the National Neonatal Lung Ultrasound Training Course and receiving 3-6 months of lung ultrasound system training at the National Neonatal Lung Ultrasound Training Center.Patients between June 2018 and May 2020 who met the RDS ultrasound diagnostic criteria and had full available clinical data were included in this study.The LUS examination was completed immediately after the patients were admitted to the hospital.Some of them also underwent chest X-ray examination.Arterial blood gas analysis was completed immediately before or after the LUS ultrasound examination.RDS grading was performed according to the LUS findings and whether the patient had serious complications.Results:A total of 275 qualifying cases were included in this study, which included 220 premature infants and 55 full-term infants, and the primary RDS occurred in 117 cases (42.5%), and secondary RDS occurred in 158 cases (57.5%). LUS manifestations of RDS patients can be divided into three categories: (1)A ground-glass opacity sign: which could be found among 50 infants when they were admitted to the hospital (that was, at their first LUS examination). Twenty-eight of these infants were considered to have wet lungs and were not sent for special management on admission, but LUS showed typical snowflake-like lung consolidation within 0.5 to 4 hours.Twenty-two of them were given mechanical ventilation with exogenous pulmonary surfactant; Eighteen cases were controlled within 6-12 hours, but the lung lesions became more severe in the other 4 infants (due to severe intrauterine infection). (2)Snowflake-like lung consolidations: the first LUS on admission showed typical snowflake-like lung consolidation involving areas ranging from 1-2 intercostal spaces to 12 lung divisions in 204 cases.Thirty-eight infants among them the lung consolidation only had involvement of 1-2 intercostal spaces at the time of admission; Fifteen of them received invasive respiratory support and recovered within 4-12 hours.Twelve patients received noninvasive respiratory support; Seven of them recovered, while five cases developed severe lung illness.The remaining 11 patients who were not given any form of ventilator support developed severe conditions within 1-4 hours.Thirty of them showed snowflake signs involving 12 lung regions at admission.The remaining 136 patients had lung consolidation degree between the two degree above condition.(3)Snowflake-like sign with complications: Twenty-one patients had severe complications such as pneumothorax, pulmonary hemorrhage or/and persistent pulmonary hypertension of the newborn or large area atelectasis, etc, although snowflake lung consolidation did not involve all lung regions.Conclusion:(1) LUS is reliable and accurate for diagnosing RDS.RDS has the same characteristics on ultrasound for both preterm and full-term infants, both primary and secondary RDS.(2) To facilitate the management of RDS, it is necessary to classify RDS according to the ultrasound findings and the presence of severe complications.(3) Based on the results of this study, it is recommended that RDS can be divided into mild, moderate and severe degrees.The exact standards for grading are as follows: Mild RDS: the early stage of RDS, in which lung consolidation shows as a ground-glass opacity sign on ultrasound; Moderate RDS: lung consolidation shows a snowflake sign on ultrasound, not all of the lung fields are involved; Severe RDS meets one or more of the following criteria: lung consolidation shows as a snowflake sign on ultrasound and all lung regions are involved, or regardless of its degree and extent, lung consolidation has caused serious complications, such as pulmonary hemorrhage, pneumothorax, persistent pulmonary hypertension of the newborn, or/and a large area of pulmonary atelectasis.
