Objective To evaluate the efficacy and safety of transarterial chemoembolization (TACE)combined with sonographically guided percutaneous microwave coagulation therapy(PMCT)for hepatic carcinoma with diameter＞5.0 cm.Methods We retrospectively reviewed 68 cases of hepatic carcinoma with diameter＞5.0 cm under treatment of TACE combined with PMCT.CT,USG and correlated laboratory tests of hepatic carcinoma were carried out.Results Among 68 cases,complete ablation were 5 cases(5/68),tumor ablation area more than 50% or tumor shrinkage less than 30% were 59 cases(59/ 68),tumor ablation area less than 50% or tumor shrinkage more than 30% were 6 cases(6/68).Forty five cases with high AFP descended more than 50% after the procedure in 42 eases(93.33%).Thirty seven cases and 29 cases with increase of CEA and CA19-9 decreased to 28(75.97%)and 23(93.10%)cases with corresponding index decreasing more than 50% respectively.Survival time reached 4-6 months in 3 cases, more than 6 months for 31 cases,more than 12 months of 34 cases.Two cases among them showed no recurrence up to now after stoppage of treatment for 24 months and finally no correlative mortality occurred. Conclusion TACE combined with sonographically guided PMCT for hepatic carcinoma with diameter more than 5 cm is safe and effective.

Objective To discuss the clinical manifestations, imaging data and DSA findings of lacunar infarction (LI). Methods One hundred and thirty-three patients, admitted to our hospital from May 2002 to April 2008, were chosen in our study; these patients with first onset as LI were confirmed by Head CT or MR; the clinical manifestations and imaging data were retrospectively analyzed; DSA was also performed on these patients and DSA findings were concluded. Results One hundred and thirty-three patients were clinically manifested as pure motor hemiplegia (PMH, n=42, 31.6%) and sensorimotor stroke (SMS, n=36, 27.1%). Two hundred and eighty-three lesions were noted by CT/MR examinations, including 78 locating at the endocyst (27.6%) and 121 locating at the corona radiate+greater oval center (91.0%). Forty-four patients were noted as having 101 intracranial vessel lesions by DSA, including 38 patients with angiostenosis, 6 with Moyamoya and 1 with single intracranial aneurysm; of the patients with angiostenosis, 95 lesions (34 in the offending vessels and 61 in other vessels) were found. Among the DSA (+) patients, PMH (n=21) and SMS (n=10) were mainly noted with their lesions locating at the endocyst (n=23) and the corona radiate+greater oval center (n=31); At least 1 high-risk factor such as hypertension, diabete, hyperlipemia, coronary heart disease and arial fibrillation was found in 44 patients. Conclusion The pathogeneses of LI are various. Main artery infarction may co-exist in some cases. PMH and SMS are common with their lesions frequently locating at basal ganglia area and corona radiate of the cerebral hemisphere. High risk factor exists in most patients with cerebrovascular diseases.

HPLC analysis was performed to study the changes in chemical composition of ginseng extracts prepared from high quality ginseng with 0, 2, 4, 8 h of steamed times. An UFLC-MS/MS multiple-reaction monitoring (MRM) quantitative analysis was made to investigate the pharmacokinetic behavior differences of ginsenosides in mice ig administered of ginseng extracts with different steamed times in the negative ion mode, with Digoxin as the internal standard substance. The mice were injected with LPS to establish inflammation model after ig administration of ginseng for a week and the contents of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in mice plasma were detected by ELISA, in order to study on anti-inflammatory effects of ginseng with different steamed times. It was determined that levels of TNF-α and IL-1β were significantly decreased in inflammation model group ig administered of ginseng extracts with 8h of steamed time. The results showed that the chemical components in ginseng changed after steaming and the components into the blood changed, correspondingly. Ginseng with steamed 8 h contributes to anti-inflammatory effects. These results provided an experimental basis for revealing the active substance basis and dose-effect relationship of ginseng on anti-inflammatory effect.

Objective To explore the association between sleep quality and the increasing risk of type 2 diabetes mellitus (T2DM).Methods A total of 771 patients aged 25-70 years living in Xuzhou City of Jiangsu Province for at least 5 years were enrolled for the survey of risk factor related noninfectious chronic disease in 2013.In this investigation,those who suffered from other types of diabetes,neuropathy,other endocrine disease,cardiovascular,renal and hepatic dysfunction,dyspnea or cancer were excluded.To reduce the influence of confounding factors,another 771 participants were enrolled as controls.Each case was arranged to have a control who was matched in age (difference not more than 3 years),gender,residence and family history.All the participants were interviewed with self-designed questionnaire,and sleep quality was measured by Pittsburgh Sleep Quality Index (PSQI) questionnaire.Student's t test,Chi-square and multivariate logistic regression were used for data analysis.Results The PSQI score in the T2DM patients vs.the controls were 5.15±2.40 vs.2.71 ± 1.93 (t=21.96,P＜0.01).The scores of sleep-related factors,including subjective poor sleep quality,bedtime resistance,short sleep duration,sleep efficiency,sleep disturbance,use of sleep medication and daytime dysfunction,of the T2DM patients were higher than those of the controls.The proportion of sleep related behaviors of the T2DM patients was higher,except for early awakening,cold feeling and nightmare.Poor sleep quality was associated with the increasing risk of T2DM (odds ratio 2.06,95％ CI 1.69-2.52).In multivariate logistic regression,when adjusted for confounding factors,the risk of T2DM was still increased (odds ratio 1.72,95％ CI 1.62-1.83).Sleep-related factors (e.g.subjective poor sleep quality,bedtime resistance,short sleep duration,sleep efficiency and sleep disturbance) were correlated with the risk of T2DM (odds ratio was 3.34,1.63,1.10,1.87 and 3.89,respectively).Conclusion Low quality of sleep may be strongly associated with an increased risk of T2DM.

Objective To observe the expression of free Ca2+ and Angiotensin Ⅱ 1 type receptor(AT1 R)in vascular smooth muscle cells(VSMCs)of patients with hypertensive or normotensive coronary artery diseases(CAD).Methods During the coronary artery bypass graft operation,the surplus saphenous vein of patients who admitted to our Cardiac Surgery Department was collected and cultured.All patients were divided into hypertensive or normotensive group.Free Ca2+ in the cultured human VSMCs was determined by confocal laser scanning microscope(CLSM)after different kinds of AngiotensinⅡ being added,respectively.Total RNA was extracted from cultured VSMCs.Then RT-PCR was conducted for the observation of the expression of AT1R in both groups.Results Ca2+in human VSMCs rapidly increased when stimulated by Angtensin Ⅱ in two groups.After stimulated by Angiotensin Ⅱ,both free Ca2+ level and the expression of AT1R in VSMCs of hypertensive patients were higher than those of the normotensive patients(P＜0.05).Conclusion There are certain changes of free calcium in the cultured human vascular smooth muscle cells,when stimulated by Angiotensin Ⅱ.There are also difierences in AT1R expression between hypertensive CAD patients and normotensive CAD patients.
