Objective: To analyze the information of patients with acute myocardial infarction (AMI) in a single center during last 6 years, and to distinguish the clinical differences of patients between TakoSTubo cardiomyopathy (TTC) and ST-segment elevation myocardial infarction (STEMI). Methods: A total of 1042 consecutive patients with primarily diagnosed acute anterior ST-segment elevation (STEMI) admitted in our hospital from 2008-01 to 2014-04 were retrospectively enrolled. The relevant patients were studied in 2 groups:TTC group, the patients with coronary angiography (CAG) and the contrast study of left ventricle corrected TTC diagnosis, n=10, and STEMI group, the patients received CAG within 6 hours of on set with conifrmed left anterior descending singlevessel disease at the same period of time as TTC patients,n=32. The basic clinical characteristics, levels of blood lipids, MI related biomarkers, the incidence rate of pathological Q wave, QTc interval and negative T wave in 12-lead ECG were compared between 2 groups. Results: The percentage of corrected TTC diagnosis in patients with primarily diagnosed STEMI was 1.06%. The female gender in TTC group and STEMI group was 100% vs 9%,P<0.01, TTC group had more patients with stress history before on set than that in STEMI group (70% vs 22%,P=0.02), lower levels of MI related biomarkers as CK (486 ± 249) U/L vs (716 ± 132) U/L, CK-MB (13.5 ± 17.1) mg/L vs (47.5 ± 21.9) mg/L, cTnI (22.8 ± 16.3) ng/mL vs (56.4 ± 24.0) ng/mL, allP<0.01. The age of morbidity, the ratios of hypertension, diabetes mellitus and blood lipids were similar between 2 groups. The frequency of abnormal Q-wave in ECG was similar between 2 groups, while the QTc interval was different in TTC group and STEMI group (630 ± 117) ms vs (540 ± 62) ms,P=0.001, the negative T waves in ECG leads II, III, aVF, aVR and V6 were as (100.00% vs 3.13%), (60.00% vs 6.25%), (90.00% vs 3.13%), (100.00% vs 21.88%), (100.00% vs 46.88%), allP<0.05. Conclusion: TTC patients with the main presentation as ST-segment elevation are usually having emotional or physical stress before on set, with obviously prolonged QTc interval and more frequency of negative T waves in ECG.

OBJECTVE:To investigate the clinical effect and safety of pregabalin combined with gabapentin in the treatment of central pain after cerebral infarction.METHODS:One hundred and fifty patients with central pain after cerebral infarction in our hospital from Jan.2010 to Dec.2015 in our department were randomly divided into group A,B,C,with 50 cases in each group.Group A was given Pregabalin capsule 75 mg,bid combined with Gabapentin capsule 0.1 g,tid;group B was given Pregabalin capsule 75 mg,bid;group C was given Gabapentin capsule 0.1 g,tid;3 groups were treated for 4 weeks.VAS score,NRS score,PSQI and SF-36 score were observed among 3 groups before and after treatment to evaluate clinical efficacies of 3 groups;the occurrence of ADR were recorded in 3 groups.RESULTS:The clinical total response rate of group A,B,C were separately 94.00％,74.00％,70.00％.The clinical total response rate of group A was significantly better than that of group B and C,with statistical significance (P＜0.05).After treatment,VAS score of group A,B,C were separately(3.87 ± 0.74),(5.10 ± 1.26),(5.03 ± 1.23);NRS score were separately (3.91 ± 0.88),(5.29 ± 1.25),(5.37 ± 1.30);VAS score and NRS score of group A were signifi cantly lower than group B,C and before treatment,with statistical significance (P＜0.05);PSQI score of group A,B,C were separately(4.03 ± 0.85),(5.92 ± 1.16),(5.83 ± 1.11);SF-36 score were separately (372.84 ± 73.25),(348.07 ± 60.54),(345.67 ± 59.72);PSQI score and SF-36 score of group A were significantly better than group B,C and before treatment,with statistical sig nificance (P＜0.05).There was no statistical significance in the incidence of ADR among 3 groups (P＞0.05).CONCLUSIONS:Compared with pregabalin and gabapentin alone,pregabalin combined with gabapentin in the treatment of central pain after cerebral infarction can efficiently relieve the perceived pain,improve sleep quality and daily life quality and not increase the risk of ADR;therefore,drug combination plan is recommended for patient with central pain after cerebral infarction,especially with poor effect of two single drug.

Objective To study on the difference of plasma renin activity ( PRA),angiotensin Ⅱ (Ang Ⅱ ),and aldosterone levels in patients with essential hypertension (EH) or primary aldosteronism (PA) or pheochromocytoma (PHEO),and to analyze the sensitivity and specificity on the diagnosis of PA among patients with hypertension with aldosterone/PRA ratio (ARR).Methods The plasma aldosterone,Ang Ⅱ and PRA concentrations in supine and upright positions were measured by radioimmunoassay from 413 patients including idiopathic hyperaldosteronism (IHA,n =111 ),aldosterone-producing adenoma (APA,n=l18),PHEO (n=98) and EH (n=86).ARR was calculated.Results Plasma aldosterone concentrations in both of supine and upright positions in PHEO group [ 374 (294,465 ) pmol/L and 629 (449,997) pmol/L] and PA group [471 (346,632) pmol/L and 673(499,825) pmol/L] were higher than those in EH group [ 277 (224,332) pmol/L and 427 (341,501 ) pmol/L ] (P ＜ 0.01 ).They were also higher in APA group [576 (416,731 ) pmol/L and 726 (554,906 )pmol/L ] than those in IHA group [399(313,504) pmol/L and 609(485,776)pmol/L ] (P ＜0.01).Ang Ⅱ levels in both positions were lower in PA group [43.2(26.4,74.4) ng/L and 60.1(38.5,103.6) ng/L] than in EH group [56.7 (43.3,78.9) ng/L and 84.3(61.3,108.4) ng/L] or PHEO group [54.3(29.9,101.5) ng/L and 102.8 (49.9,167.0) ng/L] (all P values ＜ 0.01 ),and there was no difference between IHA and APA group (P ＞ 0.05 ).The PRA level in both positions of each group were PHEO group [ 0.3 (0.2,1.0) μg ·L-1 · h-1 and 1.4(0.6,3.4) μg · L-1 · h-1] ＞EH group [0.2(0.1,0.4)μg · L-1 · h-1 and 0.6(0.4,1.0)μg· L-1 ·h-1] (P＜0.01) ＞PAgroup [0.1(0.1,0.1)μg· L-1 · h-1 and 0.2(0.1,0.3)μg·L-1 · h-1] (P＜0.01),and APA group [0.1(0.1,0.1)μg · L-1 · h-1 and0.1(0.1,0.3)μg · L-1 ·h - 1 ] ＜ IHA group [ 0.1 ( 0.1,0.2 ) μg · L - 1 · h - 1 and 0.2 (0.1,0.3 ) μg · L-1 · h - 1 ] ( supine P ＜0.01 ; upright P ＜ 0.05 ).APA was divided into 2 types with renin-Ang Ⅱ -responsive APA ( n =26) and unresponsive APA (n =92).The plasma aldosterone concentration was lower in supine position but higher in upright position in renin-Ang Ⅱ-responsive APA than in unresponsive APA patients.ARR in upright was higher in PA group ( P ＜ 0.01 ) but lower in PHEO group ( P ＜ 0.05 ) compared with EH.ARR was higher in APA than in IHA (P ＜0.01 ).The sensitivity and specificity of ARR as 40 (aldosterone unit:ng/dl;PRA unit:μg · L-1 · h-1; its value should multiply 27.7 when transferred to pmol/L,simili) were 93％ and 76％,respectively.Conclusion The levels of PRA,Ang Ⅱ and aldosterone from patients with EH,PA and PHEO are significant different.ARR as 40 in upright position could be used for PA screening cutoff point.

Fibroblast growth factor 23 (FGF23) is a bone-derived hormone that plays a central role in the regulation of calcium, phosphorus and active vitamin D levels. Recent studies have shown that high FGF23 is associated with cardiocerebrovascular diseases. This article reviews the correlation between FGF23 and cerebrovascular diseases.

OBJECTIVETo explore the clinical characteristics, and the effect of paroxysmal nocturnal hemoglobinuria (PNH) clone size and its evolution on response and survival in aplastic anemia (AA) patients.

METHODSThe clinical data of 90 AA cases with PNH clones from 316 AA patients between January 2011 and September 2014 were retrospectively reviewed, their clinical characteristics were analyzed, and the influence of PNH clone evolution and size on response and survival were explored.

RESULTS① Of 316 patients, 90 cases (28.5%) with PNH clones. Of 83 cases with long-term follow-up data available, the complete (CR) and partial response (PR) rates were 43.4% and 33.7% respectively, with the overall responsive rate of 77.1%. The 3-year and 5-year overall survival (OS)rates were 79.4% and 76.1% respectively. ② After immunosuppressive therapy (IST), the PNH clone changed from negative to positive in 24 cases, persistently positive PNH clones were observed in 22 cases, disappeared in 10 cases. There were no significant differences in terms of overall responsive rates, survival rates, absolute reticulocyte value, TBIL, IBIL and LDH among the three groups (P >0.05). Ten cases became AA-PNH after a median time of 15.6 months, no significant differences were found in overall responsive and survival rates between the 10 cases and the other 46 cases who were monitored for PNH clones (P values were 0.896, 0.688, respectively). ③ According to univariate analysis, age≥55, infection, VSAA, ANC <0.5 × 10(9)/L and absolute reticulocyte value <0.012 × 10(12)/L had significant influence on survival (P values were 0.026, 0.000, 0.001, 0.000 and 0.010, respectively). Cox regression model analysis identified that age, infection and ANC were independent prognostic factors affecting survival (P values were 0.050, 0.012 and 0.050, respectively). The PNH clone size had no significant influence on response and survival based on univariate and Cox analyses.

CONCLUSIONThe PNH clone size and its evolution had no significant influence on response and survival.

Objective: To analyze clonal evolution and clinical significance of trisomy 8 in patients with acquired bone marrow failure. Methods: The clinical data of 63 patients with acquired bone marrow failure accompanied with isolated trisomy 8 (+8) from June 2011 to September 2018 were analyzed retrospectively, the clonal evolution patterns and relationship with immmunosuppressive therapy were summarized. Results: Totally 24 male and 39 female patients were enrolled, including 39 patients with aplastic anemia (AA) and 24 patients with relatively low-risk myelodysplastic syndrome (MDS) . Mean size of+8 clone in MDS patients[65% (15%-100%) ]was higher than that of AA patients[25% (4.8%-100%) , z=3.48, P=0.001]. The patients were was divided into three groups (<30%, 30%-<50%,and ≥50%) according to the proportion of+8 clone. There was significant difference among the three groups between AA[<30%:55.6% (20/36) ; 30-50%: 22.2% (8/36) ; ≥50%22.2% (8/36) ]and MDS patients[<30%:19.0% (4/21) ; 30%-<50%:19.0% (4/21) ; ≥50%61.9% (13/21) ] (P=0.007) . The proportion of AA patients with+8 clone <30% was significantly higher than that of MDS patients (P=0.002) ; and the proportion of AA patients with+8 clone ≥50%was significantly lower than that of MDS patients (P=0.002) . The median age of AA and MDS patients was respectively 28 (7-61) years old and 48.5 (16-72) years old. Moreover, there was no correlation between age and+8 clone size in AA or MDS (r_s=0.109, P=0.125; r_s=-0.022, P=0.924, respectively) . There was statistical difference in total iron binding capacity, transferrin and erythropoietin between high and low clone group of AA patients (P=0.016, P=0.046, P=0.012, respectively) , but no significant difference in MDS patients. The immunosuppressive therapy (IST) efficacy of AA and MDS patients was respectively 66.7% and 43.8% (P=0.125) . Comparing with initial clone size (27.3%) , the +8 clone size (45%) of AA patients was increased 1-2 year after IST, but no statistical difference (z=0.83, P=0.272) . Consistently, there was no significant change between initial clone size (72.5%) and 1-2 year clone size (70.5%) after IST in MDS patients. There was no significant difference in IST efficient rate between +8 clone size expansion and decline group of in AA patients at 0.5-<1, 1-2 and>2 years after IST. We found four dynamic evolution patterns of +8 clone, which were clone persistence (45%) , clone disappearance (30%) , clone emergence (10%) and clone recurrence (15%) . Conclusions AA patients had a low clone burden, while MDS patients had a high burden of +8 clone. The +8 clone of AA patients didn’t significantly expanded after IST, and the changes of +8 clone also had no effect on IST response.

Objective: To determine the valuable hemolytic characteristics in differential diagnosis of paroxysmal nocturnal hemoglobinuria (PNH), autoimmune hemolytic anemia (AIHA) and hereditary spherocytosis (HS). Method: The clinical and hemolytic characteristics of 108 PNH patients, 127 AIHA patients and 172 HS patients diagnosed from January 1998 to April 2017 were compared. Results: ①Reticulocyte percentage (Ret%) of PNH patients [6.70% (0.14%-22.82%)] was significantly lower than that of AIHA [14.00%(0.10%-55.95%), P<0.001] and HS patients [11.83%(0.60%-57.39%), P<0.001]. The Ret% in PNH patients were significantly lower than those in AIHA and HS patients at the same levels of anemia, except for in mild anemia between PNH and AIHA patients. However, when comparing the Ret% between AIHA and HS patients, there was significant difference only in mild anemia [7.63%(1.87%-29.20%)% vs 11.20%(3.31%-22.44%), z=-2.165, P=0.030]. ②The level of TBIL in HS patients was significantly higher than that in AIHA and PNH patients [79.3 (11.2-244.0) μmol/L vs 57.6 (7.6-265.0) μmol/L, z=5.469, P<0.001; 79.3(11.2-244.0) μmol/L vs 26.2(4.6-217.7) μmol/L, z=-2.165, P<0.001], and the proportion of HS patients with TBIL more than 4 times the upper limit of normal (ULN) (64.1%) was significantly higher than that of AIHA (37.7%, χ²=19.896, P<0.001) and PNH patients (4.6%, P<0.001). ③The LDH level of PNH patients was significantly higher than that of AIHA and HS [1 500 (216-5 144) U/L vs 487 (29-3 516) U/L, z=-9.556, P<0.001; 1 500 (216-5 144) U/L vs 252 (132-663) U/L, z=-11.518, P<0.001], and the proportion of PNH patients with LDH more than 1 000 U/L (79.1%) was significantly higher than that of AIHA patients (13.0%, χ²=93.748, P<0.001) and HS patients (0, P<0.001). ④Splenomegaly occurred in 43.5% of PNH patients, including 16.0% with severe splenomegaly. In contrast, the occurrence of splenomegaly was 98.6% in AIHA patients and 100.0% in HS patients (P<0.001), and 63.0% of AIHA patients (P<0.001) and 90.4% of HS patients (P<0.001) were with severe splenomegaly. ⑤The prevalence of cholelithiasis in HS patients was up to 43.1%, significantly higher than that in AIHA patients (10.5%, P<0.001) and PNH patients (2.9%, P<0.001). Conclusion The comprehensive assessment of the five hemolytic characteristics is simplified, practical and efficient, with great clinical significance, providing specific indicators for differential diagnosis and efficient approach for making further work-up.
