We report a case of functional parathyroid cyst treated by ultrasound-guided anhydrous ethanol sclerotherapy and microwave ablation. The 63-year-old female patient was diagnosed to have functional parathyroid cyst with hypercalcemia, high PTH and cystic space-occupying lesions in the neck by ultrasound, radionuclide scanning and PTH measurement of the cystic fluid. The patient refused to receive cyst resection, and anhydrous ethanol sclerotherapy with microwave ablation was performed under ultrasound guidance. The procedure was completed smoothly without any complications either during or after the operation. Follow-up examination of the patient at 18 months after the operation showed a significant reduction of the mass and normal blood calcium and iPTH levels, demonstrating a clinical cure of the patient. Ablative treatment of functional parathyroid cyst has not been documented so far. This approach provides a minimally invasive treatment modality for such cases where surgical resection is not an option, but its efficacy and safety need to be evaluated in more cases with longer follow-up time.

OBJECTIVE: To explore the safe method with anhydrous ethanol injection in the treatment of venous malformation.
 METHODS: A total of 96 patients with venous malformation were conducted anhydrous ethanol injection for 245 times through percutaneous puncture by three-point method. The complications were observed. In animal experiment, according to the different concentrations of anhydrous ethanol injection, rats were divided into an anhydrous ethanol group, a 75% ethanol group, a 50% ethanol group and a 25% ethanol group (n=5 in each group), and the damage of vessels after ethanol injection was observed.
 RESULTS: The successful rate for three-point ethanol injection was 88%. The incidence for both skin ulcer and numbness was 0.9% without severe complications in lung and heart. In the animal experiments, the entire vessel wall including outer membrane was damaged in the anhydrous ethanol group. Part of vessel walls, including the inner membrane and muscle layer, were damaged in both the 75% ethanol group and the 50% ethanol group. However, there was no damage in the vessels in the 25% ethanol group.
 CONCLUSION With the decrease in ethanol concentration, the vascular damage is decreased and eventually disappeared. Three-point anhydrous ethanol injection is safe and effective.

OBJECTIVE: To explore the antitumor effects of ethanol extract from Ventilago leiocarpa Benth (EEVLB) on sarcoma 180 (S180) tumor-bearing mice and the potential mechanism. METHODS: Sixty mice were randomly assigned to 6 groups according to a random number table: normal group, model group, 5-fluorouracil (5-FU) group (0.02 g·kg RESULTS: EEVLB with different concentrations achieved inhibition of tumor growth in vivo, wherein the high-dose group showed the most significant reduction in tumor weight and increased apoptosis of tumor cells (P<0.05). In addition, both net weight gain and spleen index of mice showed uptrend in EEVLB treatment groups (P<0.05). Besides, serum levels of IL-2 and IL-6, percentages of CD3 CONCLUSIONS EEVLB exhibits promising antitumor activity in vivo. This effect might be due to activation of apoptotic signaling pathway, increase of cytokine levels and enhancement of immune function in tumor-bearing mice.

Previous studies of Dendrobium officinale on anti-hypertension effect always focused only on the blood pressure,while polysaccharides of D. officinale( DOP) have been traditionally considered as one of the main effective substances. This study aimed to evaluate the effect of ethanol extract from D. officinale( DOE) on blood pressure,Glu and lipid profile in metabolic hypertensive rats induced by comprehensive dietary factors,and elucidate the composition of effective fractions from DOE. A metabolic hypertension model of rat induced by high-sugar,high-fat diet and alcohol drinking was adopted to evaluate the effect of DOE on hypertension and other metabolic disorders. Blood pressure,Glu and lipid profile were detected to find the features and differences of DOE and DOP on metabolic hypertension. Furthermore,DOE was separated with three different common solvents according to the polarity. Along with blood pressure,Glu,UA and lipid profile,hemorheology,oxidative index and aortas structure changes were adopted to evaluate the comprehensive effects of the most effective fractions on metabolic hypertension. Finally,HPLC-DAD-MS was adopted to identify the components of the most effective fraction. The SBP and Glu of models were decreased significantly after administration of DOE and DOP for 6 weeks,while TG in DOE groups also reduced dramatically. The DOE was separated with ether,n-butanol respectively and named NAF,NBF and NCF. SBP,TG,Glu,UA of model rats were decreased significantly after 4 weeks administration with NBF. The level of MDA in serum was down-regulated,while GSH-Px and T-AOC were up-regulated obviously after 12 weeks.And the blood viscosity also obviously decreased,with less collagen deposition of aortas by Masson's trichrome staining. NBF was mainly composed of phenols and flavone C-glycosides,whose aglycone was apigenin,and monosaccharide was connected to C-6 and C-8. Ethanol extract from D.officinale has an positive effect in alleviating hypertension and metabolic disorders in metabolic hypertension. Medium polarity fraction was the effective fraction of alcohol extraction from D. officinale,and mainly composed of phenols and flavone C-glycosides.

OBJECTIVETo explore the curative effect of surgery and selerotherapy for massive venous malformations of the tongue.

METHODSFrom January 2005 to December 2014, subtotal resection or debulking for 15 cases of massive venous malformation in the tongue was undertaken with multiple sessions of pre- and post-operative injection therapy of pingyangmycin, lauromacrogol and absolute ethanol.

RESULTSAll signs associated with the lesions including eating, sleep and speech disorders disappeared after treatment. Complete or near complete resolution was achieved in 9 cases, and a significant reduction in size in a further 6 cases after surgical excision and peri-operative sclerotherapy.

CONCLUSIONSFor massive venous malformations of the tongue, surgical excision combined with multiple sessions of sclerotherapy is a good treatment option.

OBJECTIVETo investigate the safe and effective treatment for painful venous malformation (VM) in limbs.

METHOD(1) 97 cases with painful VM underwent MRI to detect the location of VM, as well as its size and structure, its relationship with the surrounding tissue. Statistical analysis was also performed. (2) The embolic agent (ethanol) was first injected to embolize the draining vessels of VM, then the Polidocanol plus Methotrexate (MTX) was followed to keep the embolization effect on VM. The therapeutic effect was observed and analyzed.

RESULTSFrom January 2010 to January 2012, 97 patients with painful VM were treated. A Spearman correlation analysis showed no significant correlation between symptoms of pain and lesion growth, volume, or MRI grades (P > 0.05). The lesions in the muscle space are more likely to have the symptoms of pain (P < 0.01), followed by the lesions in the muscle, then the lesions in the joint and subcutaneous tissue. The pain relieve percentage was 95.9% (93/97) after one time embolic sclerotherapy. No severe complication, such as distant embolization, nerve damage, or muscle atrophy happened. No pain reoccurrence happened after 0.5-1.5 years of follow-up period.

CONCLUSIONSThe treatment of embolic scleratherapy is minimal invasive, safe and effective for painful VM with stable results.

BACKGROUNDEffect of percutaneous transluminal septal ablation (PTSA) with ethanol injection on electromechanical remodeling of left ventricule still remains unknown. This study was conducted to assess the potential significance of cardiac electromechanical mapping (CEMM) in analyzing the left ventricular remodeling before and immediately after percutaneous transseptal myocardial ablation (PTSMA) in patients with hypertrophic obstructive cardiomyopathy (HOCM).

METHODSEight patients with drug-refractory HOCM and 6 patients with hypertrophic cardiopathy (HM) without increased left ventricular outtract gradien (LVOTG) were enrolled into the present study. CEMM was undergone in patients with HOCM before and immediately after PTSA procedure, and in patients with HM.

RESULTSPTSA was successful in all patients with HOCM, LVOTG significantly decreased from (62.87 +/- 21.16) mmHg to (12.73 +/- 3.05) mmHg immediately after ablation procedure. Value of UVP in septal-base segment in HM group was higher than that in HOCM group [(22.79 +/- 2.34) mV vs (18.54 +/- 1.76) mV]. In patients with HOCM, lateral-middle and -base segments had lowest value of UVP [(15.93 +/- 1.11) mV and (15.83 +/- 1.07) mV] before PTSA. Value of UVP at posterior-middle segment decreased from (23.58 +/- 2.21) mV pre-PTSA to (18.89 +/- 1.91) mV post-procedure, PTSA led to significant increase of UVP at lateral-middle segment. Septal region in patients with HM and septal-middle, septal-base, posterior-base segments in HOCM had lower value of local linear shortening (LLS) among all patients in both HOCM and HM groups. PTSA resulted in significant reduction of LLS in anterior region and at septal-apex segment. Anterior-base and septal-middle segments in patients with HM had lowest value of local active time (LAT), and significantly differentiated from that in patients with HOCM [(-8.57 +/- 0.68) ms vs (-18.61 +/- 1.02) ms, (-6.75 +/- 0.37)ms vs (-21.90 +/- 0.96) ms, respectively]. LAT at septal-middle and -base segments in patients with HOCM was decreased significantly [(-21.90 +/- 0.96) ms vs (-13.80 +/- 1.04) ms, P < 0.002; and (-15.20 +/- 1.06) ms vs (-6.33 +/- 0.52) ms, respectively] immediately after PTSA.

CONCLUSIONSPosterior-lateral and anterior region probably played important roles in electromechanical remodeling. Significant electromechanical remodeling disassociation (uncoupling) was detected in most left ventricular regions, which would be important in differentiating of HOCM from HM, and in predicting the prognosis in patients with HOCM after PTSA procedure.

Objective: To observe the therapeutic effects of alcohol septal ablation (ASA) in mildly symptomatic patients (NYHA class Ⅱ) with hypertrophic obstructive cardiomyopathy(HOCM). Methods: This retrospective study included 150 mildly symptomatic patients with HOCM hospitalized in Beijing Anzhen Hospital affiliated to Capital Medical University from March 2001 to December 2017, consisting of medical therapy group (n=102) and ASA group (n=48). Baseline clinical data were collected, patients were followed up to a mean of 6.0 (3.5, 8.1) years. Overall and HCM-related mortality events (including chronic heart failure, atrial fibrillation related stroke, sudden cardiac death) were observed in the two groups. Moreover, the improvement of NYHA function classification and left ventricular outflow tract gradient (LVOTG) were also evaluated. Survival analysis was performed by Kaplan-Meier method. Results: Age of this cohort was (52.9±14.5)years, 92 cases(61.3%) were male. In the follow-up, LVOTG was reduced from (85.8±35.4)mmHg (1 mmHg=0.133 kPa) to (27.7±19.8)mmHg (P<0.001) in the ASA group, and from (66.3±35.0)mmHg to (56.5±27.7)mmHg in medical therapy group(P<0.01). At the last clinical follow-up, there were 32 patients (66.7%) whose LVOTG were<30 mmHg, septal thickness decreased from (20.3±3.8)mm to (16.1±3.4)mm (P<0.001), NYHA classification was also remarkably improved (P<0.001). New-onset atrial fibrillation tended to be lower in the ASA group compared to medical therapy group (9.3%(4/43) vs. 20.8%(20/96),P=0.096). Eleven patients (10.8%) in the medical therapy group and 2 patients (4.2%) in the ASA group died during the follow-up. One patient received pacemaker during the peri-procedural period, 1 patient was implanted with two-chamber pacemaker due to Ⅲ° atrioventricular block at 10 years after operation in the ASA group. Survival free of all-cause mortality of ASA group at 5 and 10 years was 97.9% and 97.9%, respectively, which was comparable to the medical therapy group (P=0.231). Survival free of HCM-related mortality was similar between the two groups (P=0.397). Conclusions: Compared with medical therapy in mildly symptomatic patients with HOCM, long-term survival rate is similar after ASA. Meanwhile, ASA can remarkably reduce LVOTG and improve the clinical status of the patients. Therefore, ASA may be used as an alternative therapy for mildly symptomatic HOCM patients.
