Objective To observe the efficacy and safety of trimetazidine/coenzyme Q10 combination in the treatment of the elderly patients with chronic heart failure(CHF).Methods Sixty-two male patients aged over 80 years with CHF were randomly divided into intervention group and control group.Patients in control group received optimal conventional CHF therapy according to the guideline for CHF,while patients in intervention group received trimetazidine of 20 mg,3 times per day,coenzyme Q10 20 mg,3 times per day,additionally for 6 weeks.Left ventricular ejection fraction (LVEF),left ventricular end diastolic diameter (LVEDD),plasma brain natriuretic peptide (BNP),6 min walking distance (6MWT) and NYHA cardiac function classification of two groups before and after treatment were observed.Results Before treatmen,the NYHA function class of patients in intervention and control groups were 2.8±0.7,2.7±0.7 respectively,after treatment were 2.1± 0.6,2.4 ± 0.7 respectively,the differences were significant before and after treatment (t=6.808,2.249;P＜0.01,P＜0.05).Before treatment,BNP of intervention and control groups were (540±351)ng/L,(483 ± 351) ng/L respectively,after treatment were (219± 172) ng/L,(316 ± 202) ng/L respectively,the differences were significant before and after treatment (Z =-4.927,-4.042;P ＜ 0.01).Moreover,after treatment,NYHA function class and plasma BNP in intervention group were significantly better than those in control group (t =-2.109,P ＜ 0.05;Z =-2.219,P ＜ 0.05).Before treatment,LVEF,LVEDD and 6MWT of intervention group were (44.3 ± 3.1) ％,(54.0 ± 4.7) mm and (217.0 ± 60.9) m respectively,after treatment were (46.8±3.9) ％,(53.2±4.3) mm and (267.0±91.1) m respectively,the differences were significant before and after treatment(t=-8.313,2.254,-4.561;P＜0.01 or P＜0.05).Moreover,after treatment,LVEF and 6MWT in intervention group were significantly better than those in control group ((44.9± 3.5)％,(213.2 ±78.1) m;t =2.000,2.186;P ＜ 0.05).No significant adverse events were detected in the intervention group.Conclusion Combination of trimetazidine and coenzyme Q10 on the basis of the conventional treatment in the elderly with CHF,can further improve cardiac dysfunction and have a good safety.

Objective To investigate the effects of Furong-Tongmai capsules on the expressions of interleukin-1 (IL-1) and tumor necrosis factor-α (TNF-α) in the sciatic nerve in diabetic rats.Methods A total of 50 rats were randomly divided into the normal control group,model group,and low-,medium-,and high-dose of Furong-Tongmai groups,10 rats in each group.Diabetes mellitus in rats were induced by intraperitoneal streptozotocin injection (60 mg/kg).The rats in the low-,medium-,and high-dose of Furong-Tongmai groups were intragastric administrated with Furong-Tongmai suspension 0.7,1.4 and 2.8 g/kg daily for 8 weeks,respectively.The rots in the normal control group and model group were intragastric administrated with equal-volume normal saline daily for 8 weeks.The expression levels of IL-1 and TNF-α in the sciatic nerve were detected with immunohistochemistry staining.Results The expression levels of IL-1 (1.43％ ± 0.17％ vs.0.21％ ± 0.09％;P＜0.05) and TNF-α (1.98％ ± 0.12％ vs.0.35％ ± 0.03％;P＜0.05) in the model group were significantly increased than those in the normal control group.The expression levels of IL-1 (0.54％ ± 0.14％,0.51％ ± 0.13％ vs.1.43％ ± 0.17％;all P＜0.05) and TNF-α (0.57％ ± 0.17％,0.49％ ± 0.15％ vs.1.98％ ± 0.12％;all P＜0.05) in the medium-,and high-dose of Furong-Tongmai groups were significantly decreased than those in the model group and low-dose of Furong-Tongmai group (1.08％ ± 0.18％ in IL-1,1.11％ ± 0.09％ in TNF-α;all P＜0.05).Conclusion Furong-Tongmai capsules can reduce the expressions of IL-1 and TNF-α in sciatic nerve in diabetic rats.

Objective To explore the the influence ofFurong-Tongmai capsules on myocardial expression of LN and CollagenⅢ in diabetes mellitus (DM) rats.Methods A total of 60 rats were randomly divided into the control group, the model group, the low-, middle- high-dosageFurong-Tongmai capsules group (n=10). The low-, middle-high-dosageFurong-Tongmai group was given 1.4, 0.7, 2.8 g/(kg body weight) Furong-Tongmai capsules. The other two groups were given the same dose of purified water. After 8 weeks treatment, the myocardial was taken to make pathology slice with SP immunohistochemistry staining. The expression of LN and CollagenⅢ were detected.Results Compared with model group, the expression of LN (0.67% ± 0.04%,0.65% ± 0.09%vs. 1.08% ± 0.13%) and CollagenⅢ (0.67% ± 0.15%, 0.69% ± 0.13%vs. 1.17% ± 0.12%) in the middle-high-dosageFurong-Tongmai groups significantly decreased (P<0.05). However, there were no statistical differences between the low-, middle- high-dosageFurong-Tongmai groups and the model group (P>0.05).Conclusions TheFurong-Tongmai capsules could inhibit the expression of LN and CollagenⅢ in DM rats.

SUMMARY To investigate the effect and feasibility of total laparoscopy to treat hepatolithiasis using gall-bladder-hepatic duct subcutaneous tunnel.Retrospective analysis was conducted of the case data of 11 pa-tients with hepatolithiasis who underwent total laparoscopic treatment using gallbladder-hepatic duct sub-cutaneous tunnel from January 2010 to October 2014.The operation time,blood loss,postoperative com-plications and recurrence of stones were recorded.All the cases completed the operation.The average hos-pital-stay was 9.2 days (range:3 -29 d).The average operation time was 298 min (range:225 -480 min).The average blood loss was 253 mL (range:50 -700 mL),and the average blood loss of liver re-section groups was 325 mL (range:200 -700 mL).The average discharge time was 3.3 days (range:3 -5 d).The rate of postoperative residual stones was 36.4% (4 /11).We extracted stones with chole-dochofiberscope via T-tube sinus six weeks after operation.One case developed biliary leakage,and healed through adequate drainage and the T-tube was pulled out after one month.There was no periopera-tive mortality.All the cases were followed up and the mean follow-up was 22 months (range:2 -51 months).The anastomotic stenosis of gallbladder-hepatic duct was found in one case.But we got a good therapeutic result with performed gallbladder chemical ablation with 95% ethanol.No recurrence of hepa-tolithiasis was found.As a choice for minimally invasive method to hepatolithiasis using gallbladder-he-patic duct subcutaneous tunnel,total laparoscopy is a safe and feasible procedure.

Objective Percheron artery is an uncommon anatomic variant. Percheron artery infarction with unilateral embryonic posterior cerebral artery ( PCA ) was rarely reported.The aim of this study was to characterize the clinical and imaging patterns of Percheron artery infarction with the unilateral embryonic PCA for early diagnosis and treatment.MethodsClinical and imaging data of 2 patients with Percheron artery infarction were reviewed retrospectively.ResultsTwo patients presented acute coma and one had paroxysmal blurred before coma.On neurological examinations,one patient had vertical gaze palsy besides two were unconsciousness. MRI showed symmetrical high signal intensity on diffusion weighed imaging (DWI)in bilateral paramedian thalami in two patients and a distinct pattern of V-shaped hyperintensity on DWI andFLAIR was present on the midbrain in one patient. Digital subtraction angiography and magnetic resonance angiography demonstrated unilateral embryonic PCA in two patients.ConclusionsThe classical clinical symptoms,symmetrical high signal in bilateral paramedian thalami and V-shaped sign in midbrain on DWI can improve recognition,evaluation and management of Percheron artery infarction.The unilateral embryonic PCA may be underlying risk factor of Percheron artery infarction.

Objective To investigate the value of CT in localization diagnosis of the neoplasm of the transverse mesocolon.Methods 26 cases of neoplasm of the transverse mesocolon proved by surgical pathology or pathology from May 1998 to Dec.2007 were retrospectivley studied.All cases underwent CT scan.Image analysis was focused on the relation between neoplasm and SMA,SMV,middle colonic vessels,duodenum,and the small bowel.Readipose sarcoma (n=1),transverse colonic carcinoma invaded the transverse melocolon (n=2),pancreatic carcinoduodenum in 22 cases.Superior mesenteric artery and vein were displaced in 21 cases;middle colonic vessels were showed different CT manifestation.Conclusion The relation between neoplasm and adjacent structure is helpful for the localizing neoplasm of the transverse mesocolon.

Objective To examine the recurrent ischemic stroke(RIS)in hospitalized patients predicted by Essen Stroke Risk Score(ESRS)and investigate the effect of intensive antiplatelet therapy in patients with high risk of RIS. Methods Retrospective analysis of patients with acute noncardioembolic ischemic stroke consecutively admitted to Peking Union Medical College Hospital(PUMCH)during 2001-2008. All 1008 patients were included in this study, 377 hospitalized in 2001-2002, 315 in 2005 and 316 in 2008. High risk of RIS was defined as ESRS ≥3. The average ESRS score in three groups and percentage of patients with high risk of RIS in each group were calculated. Risk of RIS was evaluated by comparing the average ESRS score in these three groups. Patients with high risk and taking clopidogrel treatment were also evaluated. Results Average ESRS score was 2. 67 ± 1.47,3.55 ± 1.40 and 3.93 ± 1.48(F= 150. 85,P=0.000)in groups of patients hospitalized in 2001-2002, 2005 and 2008 respectively. A significant difference was shown in percentage of high risk patients with ESRS ≥3 in three groups: as 51.64% in 2001-2002,77. 19% in 2005 and 85. 45% in 2008(X2=98.30,P=0. 000),showing a trend of increasing risk of RIS. Except for patients age, rates of having the risk factors in patients increased significantly, including hypertension, diabetes, myocardial infarction, myocardial diseases, smoking,vascular disease and stroke history. Clopidogrel usage has been increasing to 25.63% in 2008, but was far behind high ratio of high risk RIS patients(85.45%). Conclusions This retrospective study showd an increasing trend in RIS risk during 2001-2008. Identifying high risk patients and applying intensified antiplatelet therapy might play an important role in reducing the risk of RIS.

Objective To assess the relationship of serum prealbumin level with the severity of acute ischemic stroke (AIS).Methods The clinical data of 2522 AIS patients who were admitted in Peking Union Medical College Hospital from 2000 to 2008 were retrospectively analyzed.The serum prealbumin and hypersensitive C-reactive protein (hs-CRP) levels were evaluated by immunoturbidimetric assay within 24 hours after admission.The AIS severity was evaluated at admission using modified Rankin Scale (mRS).Patients were divided into mild AIS group (mRS score ≤ 3 ) and severe AIS group (mRS score ＞ 3 ).The levels of serum prealbumin and hs-CRP were compared between these two groups,and the relationship between praalbumin and hs-CRP was also analyzed.Results There were 1697 patients in the mild group (average mRS score:1.67) and 825 patients in the severe group ( average mRS score:4.53 ).The severe group had significantly lower prealbumin level [ ( 191.20,82.00)versus (219.18,72.00) mg/L,P =0.000] and higher hs-CRP level [ (6.01,8.22) versus (4.15,6.93) mg/L,P =0.000 ] than the mild group,respectively.Partial regression analysis showed that the stroke severity was negatively correlated with serum prealbumin level (r =-0.115,P =0.000) and positively correlated with hs-CRP level (r =0.098,P =0.000).Serum prealbumin level was inversely correlated with hs-CRP level ( r =- 0.396,P =0.000).Conclusion The prealbumin level is relevant with the severity of AIS and inflammation.

Objective To investigate the prevalence of hyperuricemia in health check-up population of Beijing suburb.Methods Total 1 336 rural residents in Nankou Township of Beijing received health check-up from July to Aug 2014,including 686 subjects aged 20-59 years (young/middle-aged group) and 650 subjects aged 60-96 years (elderly group).The blood pressure and body mass index (BMI) were measured;serum uric acid (SUA),fasting blood glucose (FBG) and blood lipids (TG,TC,HDL-C,LDL-C) were determined.The SUA levels ＞ 420 μmol/L for male and ＞ 360 μmol/L for female were defined as hyperuricemia.Results The four quartiles of SUA levels were 27.00-254.59 μmol/L (Q1),254.60-302.35 μmol/L (Q2),302.36-359.78 μmol/L(Q3) and 359.79-702.0 μmol/L (Q4).The prevalence of hyperuricemia was significantly higher in young/middle-aged group than that in elderly group [20.41％ (140/686) vs.13.85％ (90/650),x2 =10.08,P =0.001 5],the systolic blood pressure [SBP,(126.8±15.7) vs.(116.7±12.0)mmHg(1 mmHg=0.133 kPa),t=2.76,P=0.008],FBG [(7.40±4.10) vs.(6.11 ±2.03)mmol/L,t=2.12,P=0.036],TC [(5.52±1.10) vs.(5.23±1.00)mmol/L,t =2.04,P =0.045],LDL-C [(3.5 ±0.7) vs.(2.4 ±0.9)mmol/L,t =2.21,P =0.029]in young/middle-aged group were significantly higher than those in elderly group.BMI,FBG were significantly higher in Q4 than those in other quartiles [BMI:(26.44 ± 3.88) vs.(24.19 ± 3.37),(25.49±3.42) and (25.61 ±3.49)kg/m2,t =2.78,P=0.008;FBG:(8.19 ±1.52) vs.(6.34±1.34),(6.09 ± 1.51) and (6.40 ± 1.98) mmol/L,t =2.80,P =0.007].The triglyceride (TG) levels in group Q3 and Q4 [(1.85 ± 0.90) and (1.92 ± 0.44) mmol/L] were higher than those in Q1 and Q2 [(1.37 ±0.76) and (1.70 ±0.84) mmol/L,t =2.1,P =0.035].Only 9.57％ subjects (22/230)with hyperuricemia was not combined with metabolic disorder;subjects combined with one and two metabolic disorders accounted for 20.87％ (48/230) and 69.57％ (160/230),respectively.Conclusion Screening for hyperuricemia is important for comprehensiye treatment and management of hyperuricemia in rural residents,especially in the young and middle-aged population.

Objective To investigate the clinical feactures of patients with numerous dilated Virchow-Robin space in basal gangalia.Methods Eight patients with cribriform state in striatum in brain MRI at Peking Union Medical College Hospital from March 2013 to October 2013 were enrolled.The clinical data including age,gender,common vascular risk factors and clinical manifestations were analyzed.Cognitive functions,balance and gait disturbance,as well as activity of daily living were assessed.Results All of the eight patients are male,aged from 69 to 80.All the patients had a history of hyperlipidemia,while 7 of them had hypertension.The primary complaint was either gradual motor function decline or memory impairments (3/8),or dizziness (1/8).The other 4 of them were diagnosed as stroke or transient ischemic attack.Among the 8 patients,four had mild deterioration in activity of daily living function (Barthel index 65-85).Cognitive impairment was common (8/8,the Montreal Cognitive Assessment scores 19-27),while word recall was the mostly affected cognitive domain (8/8).Gait and balance dysfunction were found in three patients (3/8,Tinetti scores ≤ 24).Conclusions Man is more likely to have predisposition to cribriform state in striatum.Mild cognitive impairments and gait abnormality are common clinical manifestations of the disease.
