Integrative molecular characterization of Chinese prostate cancer specimens / 亚洲男科学杂志(英文版)

Prostate cancer (PCa) exhibits epidemiological and molecular heterogeneity. Despite extensive studies of its phenotypic and genetic properties in Western populations, its molecular basis is not clear in Chinese patients. To determine critical molecular characteristics and explore correlations between genomic markers and clinical parameters in Chinese populations, we applied an integrative genetic/transcriptomic assay that combines targeted next-generation sequencing and quantitative real-time PCR (qRT-PCR) on samples from 46 Chinese patients with PCa. Lysine (K)-specific methyltransferase 2D (KMT2D), zinc finger homeobox 3 (ZFHX3), A-kinase anchoring protein 9 (AKAP9), and GLI family zinc finger 1 (GLI1) were frequently mutated in our cohort. Moreover, a clinicopathological analysis showed that RB transcriptional corepressor 1 (RB1) deletion was common in patients with a high risk of disease progression. Remarkably, four genomic events, MYC proto-oncogene (MYC) amplification, RB1 deletion, APC regulator of WNT signaling pathway (APC) mutation or deletion, and cyclin-dependent kinase 12 (CDK12) mutation, were correlated with poor disease-free survival. In addition, a close link between KMT2D expression and the androgen receptor (AR) signaling pathway was observed both in our cohort and in The Cancer Genome Atlas Prostate Adenocarcinoma (TCGA-PRAD) data. In summary, our results demonstrate the feasibility and benefits of integrative molecular characterization of PCa samples in disease pathology research and personalized medicine.

Research of mechanism jinxueyuan granules increased saliva secretion of xerostomia model rats / 中国中药杂志

To analyze the specific mechanism of Jinxueyuan granules, the relationship between the Jinxueyuan granules increased the saliva secretion of xerostomia model SD rats and excitement of receptors were studied in this experiment. In the study, three groups of xerostomia model rats were successfully established by using M-receptor blockers-4-diphenyl-acetoxy-N-methyl-piperidine (4-DAMP) and atropine, or adrenergic receptor blocker phentolamine; after the modeling, the medicine Jinxueyuan granules were gavaged. According to the clinical dose of Jinxueyuan granules and SD rats body surface area, the rats in atropine group were divided three dose groups respectively, namely low, medium and high dose of Jinxueyuan granules groups. The 4-DAMP group and phentolamine group were gavaged medium dose of Jinxueyuan granules. And the amount of salivary secretion for 150 minutes in all groups continuously were measured, and the effect of Jinxueyuan granules increased salivation and the relationship between characteristics and the receptors were observed; and submandibular gland tissue of the rats was isolated, then the effect of Jinxueyuan Granules for expression of the water channel protein aquaporin-5 (AQP5) in submandibular gland cells was analyzed by the Western blot technology. It was found that the saliva secretion of Jinxueyuan Granules groups was increased significantly, and compared with the saline control group, phentolamine group, 4-DAMP group and atropine group, difference was significant, P < 0.05. There was no significant difference between the low-dose of Jinxueyuan granules group and the saline group, but the medium dose of Jinxueyuan granules group had a significant difference, compared with the saline group (P < 0.05). In the time distribution of increasing saliva secretion, there was a significant difference between the saline and Jinxueyuan granules group in the saliva secretion (P < 0.05). After administration of Jinxueyuan granules, the expression of AQP5 protein in the submandibular gland cells expressing of treatment groups was increased, and compared with the blocker groups, there was a significant difference, P < 0.05. Except the atropine group, there was no significant difference in Jinxueyuan granules relieving the inhibition induced by blocks in phentolamine group and 4-DAMP group, compared with the saline group. Compared the AQP5 expression in three blockers groups, there was no significant difference in the efficacy of Jinxueyuan granules between phentolamine group and 4-DAMP group; but there was a significant difference between the atropine group and other groups (P < 0.05). Therefore, it was considered that the mechanism of Jinxueyuan granules increasing saliva secretion (effectiveness of nourishing Yin and generating body fluid ) possibly through the pathway mediated by muscarinic M receptor, especially M3 receptor, or adrenergic receptor, and increased expression of salivary gland AQP5 membrane, and then stimulate saliva production.

Effect of aliskiren on arterial stiffness, compared with ramipril in patients with mild to moderate essential hypertension / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Aliskiren is a novel blood pressure-lowering agent acting as an oral direct renin inhibitor. The aim of this study was to assess the effect of aliskiren on arterial stiffness, compared with that of ramipril in mild to moderate essential hypertensive patients.</p><p><b>METHODS</b>Following a two week placebo run-in period, patients with a mean sitting diastolic blood pressure (ms-DBP) ≥ 95 and < 110 mmHg (1 mmHg = 0.133 kPa), and a mean sitting systolic blood pressure (ms-SBP) < 180 mmHg were randomly allocated to treatment with aliskiren (150 mg/d, n = 20) or ramipril (5 mg/d, n = 20) for eight weeks. Blood pressure, plasma renin activity, and the brachial-ankle pulse wave velocity (ba-PWV) were measured before and after eight weeks of treatment.</p><p><b>RESULTS</b>Eight weeks of treatment significantly decreased systolic blood pressure and diastolic blood pressure in both the aliskiren group and ramipril group. The hypotensive effect did not differ between the two groups. Plasma renin activity decreased after aliskiren treatment and increased after ramipril treatment. There was no significant difference in baseline ba-PWV between the aliskiren and ramipril groups (P = 0.892). The ba-PWV was significantly reduced in both the aliskiren group (1535 (1405 - 1666) vs. 1464 (1360 - 1506) cm/s) (P < 0.01) and the ramipril group (1544 (1433 - 1673) vs. 1447 (1327 - 1549) cm/s) (P < 0.01). No statistically significant difference was found in the decline of ba-PWV between the two groups (P = 0.766).</p><p><b>CONCLUSIONS</b>The current study revealed that aliskiren (150 mg/d) could ameliorate arterial stiffness and its effect was similar to ramipril (5 mg/d) in mild to moderate hypertensive patients, indicating that in addition to lowering blood pressure, aliskiren had beneficial effect on vascular protection.</p>

Recombinant human thrombopoietin in combination with cyclosporin A as a novel therapy in corticosteroid-resistant primary immune thrombocytopenia / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The management of patients with refractory immune thrombocytopenia (ITP) is challenging, as there is no standard treatment option. The aim of this study was to investigate the efficacy of recombinant human thrombopoietin (rhTPO) in combination with cyclosporin A (CsA) for the management of patients with corticosteroid-resistant primary ITP.</p><p><b>METHODS</b>Thirty-six patients with corticosteroid-resistant ITP were randomly divided into an observation group and control group. In the observation group, 19 patients received subcutaneous injection of rhTPO at a dose of 1 µg/kg (300 U/kg) once daily up to day 14. Simultaneously they also received oral CsA at a dose of 1.5-2.0 mg/kg twice daily for three months. In the control group, rhTPO alone was administered subcutaneously at 1 µg/kg once daily in the other 17 ITP patients for 14 consecutive days and then the treatment was withdrawn.</p><p><b>RESULTS</b>There was no significant difference in the response rate at the end of the first week after treatment initiation between the observation group and the control group (63.2% vs. 58.8%, P > 0.05), neither was there at the end of the second week (89.5% vs. 94.1%, P > 0.05). However, the relapse rate in the observation group was significantly lower than that in control group at the end of the first (17.7% vs. 50.0%, P < 0.05), second (29.4% vs. 68.8%, P < 0.05) and the third month (29.4% vs. 87.5%, P < 0.01). In addition, rhTPO plus CsA were well tolerated and adverse events recorded were mild.</p><p><b>CONCLUSIONS</b>Combination therapy with rhTPO and CsA was effective in the management of patients with corticosteroidresistant ITP, with a relatively short time to response and low recurrence rate. It might be considered as a potential secondline treatment regimen for ITP.</p>

Status of glucose metabolism in Chinese essential hypertensive patients / 中华心血管病杂志

<p><b>OBJECTIVE</b>To investigate glucose metabolism status and its relationship with blood pressure, obesity, renal function and cardio-cerebral vascular events in Chinese essential hypertensive patients.</p><p><b>METHODS</b>Essential hypertensive patients without diabetic history were enrolled in this cross-sectional survey. All patients filled in questionnaires and received physical examination and laboratory tests. Oral glucose tolerance test (OGTT, fasting and 2 hours glucose level after drinking the 75 g glucose solution) was performed in patients who signed the informed consent.</p><p><b>RESULTS</b>(1) The control rate of systolic BP was lower in patients with dysglycemia than in patients without dysglycemia (41.0% vs. 46.4%, P = 0.000). (2) The albuminuria detection rate and the abnormal rate of estimated glumerular filtration rate (eGFR) increased significantly with the deterioration of glucose metabolism. (3) Multifactor-analysis showed that abnormal waist circumference, decreased eGFR and presence of albuminuria were independent risk factors for abnormal glucose metabolism. Cardiovascular events was significantly higher in patients with abnormal glucose metabolism than patients with normal glucose metabolism.</p><p><b>CONCLUSION</b>Abnormal glucose metabolism is common in Chinese essential hypertensive patients. When complicated with abnormal glucose metabolism, essential hypertensive patients had poor blood pressure control rate and were related to higher cardiovascular risk.</p>

Changes of platelet α-particle membrane protein, platelet activating factor and platelet parameters in patients with hyperuricemia / 中国实验血液学杂志

This study was aimed to investigate the changes of the platelet particle membrane protein (GMP-140), platelet activating factor (PAF) and platelet parametes in the patients with hyperuricemia (HUA), ELISA was used to detect the levels of GMP-140 and PAF in 55 patients with HUA and 30 healthy individuals. Platelet parameters were measured with automatic blood cell analyzer, and the biochemical indexes were detected at the same time. The results showed that the levels of serum uric acid, triglycerides (TG) and low density lipoprotein cholesterol (LDL-C) in HUA patients were higher than that in the normal group (P < 0.01). Serum uric acid level of HUA group was higher in men than that in women. The levels of GMP-140 and PAF in HUA patients were much higher than that in the normal group (P < 0.01), the indexes of platelet distribution width (PDW) and platelet-large cell ratio (P-LCR) in HUA patients were higher than that in the normal group (P < 0.01), there was no statistically significant difference in platelet count, plateletcrit (PCT), mean platelet volume (MPV) between the two groups. There was positive correlation between serum uric acid and levels of GMP-140, PAF, P-LCR and PDW, respectively (r = 0.667, 0.879, 0.310, 0.460, P < 0.01 or P < 0.05). Multivariate stepwise regression analysis revealed that serum uric acid, creatinine, P-LCR, urea nitrogen contributed to GMP-140 level (adjusted R(2) = 0.822). Serum uric acid and LDL-C also contributed to PAF level (adjusted R(2) = 0.451). It is concluded that a close relationship exists between HUA and the change of platelet function, and HUA plays a certain role in cardiovascular disease thrombosis complications.

This study was aimed to explore the expression of erythropoietin receptor (EPOR) on acute leukemia cells and its clinical significance. Bone marrow of 40 patients with acute leukemia (AL) and 24 patients with normal bone marrow as control group were collected. Samples came from outpatients and inpatients in our hospital. EPOR mRNA was detected by reverse transcription-PCR. The results showed that there was EPOR expression on AL cells, the expression rate was 57.5%, and the average expression level (Gray value) was 0.3549 ± 0.2800, but both were lower than that in control group (p < 0.05). There was no significant statistic difference of expression rate between acute myelogenous leukemia (AML) and acute lymphoblastic leukemia (ALL) (p > 0.05), and expression level of AML EPOR was higher than that of ALL (p < 0.05). It is concluded that there is EPOR expression on AL cells, while the expression rate and expression level are lower than those in control group (p < 0.05). There is no significant statistic difference of the expression rate between AML and ALL (p > 0.05), and the expression level of AML EPOR is higher than that of ALL (p < 0.05).

Plasma suPAR level in patients with multiple myeloma / 中国实验血液学杂志

To investigate the changes of plasma suPAR level in patients with multiple myeloma, ELISA was used to detect plasma suPAR level, and routine examination was performed for other clinical indexes in 26 multiple myeloma patients. The results showed that plasma suPAR level in patients was 4.31+/-1.67 ng/ml, which was obviously higher than that in control group (1.87+/-0.27 ng/ml) (p<0.01). Plasma suPAR level in IgM subtype patients was 6.18+/-3.61 ng/ml, which was highest among all the subtypes; the plasma suPAR levels in non-secretion subtype, IgG and IgA subtype were 4.43+/-1.55 ng/ml, 4.00+/-0.95 ng/ml and 3.50+/-1.60 ng/ml respectively. The plasma suPAR levels in all subtypes were higher than that in control group, but there was no differences between these subtypes. SuPAR level was correlated with the blood sedimentation rate, creatinine level and hemoglobin level, plasma cell ratio and M protein level. It is concluded that the change of plasma suPAR level in multiple myeloma contributes to predict the development and prognosis of the disease.

At the end of the single-blind run-in period, those patients with DBP >or= 95 mm Hg (n = 864) were randomized in 1:1 ratio to Valsartan and Valsartan 80 mg (n = 429)/HCTZ80/12.5 mg (n = 435) treatment o.d. for 8 weeks. Safety and efficacy was assessed every 4 weeks during double blind phase.</p><p><b>RESULTS</b>At the end of study, valsartan/HCTZ 80/12.5 mg combination treatment further reduced systolic (-3.5 mm Hg) and diastolic (-2.2 mm Hg) pressures and increased the rate of patients reaching goal BP level (53.9% vs. 40.9%) compared to valsartan 80 mg o.d. monotherapy. Incidence of side effects was similar between the combination therapy and monotherapy groups (8.9% vs. 5.1%, P > 0.05).</p><p><b>CONCLUSION</b>Efficacy of Valsartan 80 mg/HCTZ 12.5 mg compound was superior to valsartan 80 mg on BP reduction and goal BP control rate in Chinese patients with mild to moderate essential hypertension. The combination of Valsartan 80 mg/hydrochlorothiazide (HCTZ) 12.5 mg provides a suitable treatment for Chinese patients who are not adequately controlled by valsartan 80 mg o.d. monotherapy.</p>

Retrospective survey on clinical characteristics and therapy management for hospitalized patients with essential hypertension in Beijing / 中华心血管病杂志

<p><b>OBJECTIVE</b>To evaluate the clinical characteristics and therapy conditions in hospitalized patients with essential hypertension in Beijing.</p><p><b>METHODS</b>Patients with essential hypertension hospitalized in 20 Beijing hospitals in recent 2 years were included in this epidemiologic retrospective survey. Data on age, blood pressure level, risk factors and complicated diseases, antihypertensive medication and heart structural and functional characteristics measured by echocardiography were collected.</p><p><b>RESULTS</b>Total 5106 hospitalized patients (mean age 63.78 years) with essential hypertension were recorded. Mean blood pressure was 145.97/84.23 mm Hg (1 mm Hg = 0.133 kPa). Among them, 75.5% complicated with at least one risk factor, 30% suffered from heart failure. The atria enlargement and left ventricular diastolic dysfunction were the two most common echocardiographic pathological changes. Left ventricular hypertrophy is positively correlated with blood pressure. Logistic regression analysis showed that increased systolic blood pressure, diastolic blood pressure and plasma creatinine, old age and decreased HDL-cholesterol were risk factors of left ventricular hypertrophy. Only 32.1% patients achieved the goal blood pressure level (<140/90 mm Hg) and 38.1% patients were treated with monotherapy. The most commonly used antihypertensive drugs were calcium channel blockers and diuretics.</p><p><b>CONCLUSIONS</b>It is of importance to strictly follow the therapy guidelines on hypertension treatment and use combined drug therapy to increase the rate of patients reaching goal blood pressure level and reduce hypertensive complications.</p>

Expression of CD133 in bone marrow cells of patients with leukemia and myelodysplastic syndrome / 中国实验血液学杂志

To explore the relationship between the expression of CD133 and pathogenesis of leukemia and MDS, immunocytochemistry method was used to examine the expression of CD133 in bone marrow cells of patients with leukemia and MDS. The results showed that the positive rate of CD133 in 41 acute leukemia patients was 51.2%. The expression of CD133 in AML patients (16/29, 55.2%) was significantly higher than that in control group (2/15, 13.3%). There was no significant difference in CD133 expression between CML and control group. The positive rate of CD133 in 9 patients with MDS was 55.56% (5/9). There was no significant difference between MDS and normal control. The expression of CD133 in all leukemia cells with CD34(+) was higher than that in leukemia cells with CD34(-), and there was significant difference in expression of CD133 between them (P < 0.05). The expression of CD133 had no relationship with the clinical prognostic factors such as sex, age, the percentage of leukemic cells in peripheral blood and in bone marrow, WBC counts, hemoglobin concentration, platelet counts and LDH level. It is concluded that the expression of CD133 in bone marrow cells of patients with AML is higher than that in control group. The expression of CD133 is significantly correlated with the expression of CD34. The high expression of CD133 may be an adverse prognostic factor in acute leukemia.

Prognostic analysis of surgical resection for patients with liver metastases from gastric cancer / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To assess the indication and efficacy of surgical treatment for patients with hepatic metastases from gastric cancer.</p><p><b>METHODS</b>Clinical data of 43 patients with hepatic metastases from gastric cancer undergoing surgery from September 1995 to May 2002 were analyzed retrospectively.</p><p><b>RESULTS</b>No relationships were found between the number of hepatic metastases and patient's gender, age, tumor invasion depth, lymphatic node metastases and differentiation P> 0.05. All of 43 patients underwent surgery. Four cases undergoing hepatic resection for metachronous hepatic metastases had a higher survival rate than those who had curative resections for synchronous hepatic metastases (median survival 35 months vs. 10 months) (P=0.0233). 39 patients had synchronous hepatic metastases, of whom 32 patients received gastric resection only and 7 patients received both gastric and hepatic resections, there was significant difference of median survival between synchronous group and metachronous group(median survival 6.0 vs. median survival 10.0 months)(P=0.2799). There was significant difference of the postoperative survival rate among H (1) (7.5 months), H (2) (6 months) and H (3) (4 months) in the patients with palliative gastric resections (P=0.0007).</p><p><b>CONCLUSION</b>Hepatic resection for metachronous hepatic metastases from gastric cancer has a better prognosis. Resections of gastric and hepatic lesions at the same time may not benefit the patients with liver metastases from gastric cancer. H(3) is not feasible for palliative gastric resections.</p>

Expression and clinical significance of PTTG and b-FGF in acute leukemia / 中国实验血液学杂志

To investigate the expression of pituitary tumor-transforming gene (PTTG) and basic fibroblast growth factor (b-FGF) in acute leukemia, as well as the relationship of their expression with prognosis in acute leukemia, expressions of PTTG and b-FGF in acute leukemia (AL) specimens were detected by immunocytochemical technique. The results showed that the expressions of PTTG and b-FGF in AL group were higher than that in the control group significantly (P < 0.01). In AL group, after chemotherapy, the expression of PTTG and b-FGF in de novo patients group was higher than in the complete remission patient group significantly (P < 0.01). The expressions of PTTG and b-FGF showed positive correlation (r = 0.61, P < 0.01). It is concluded that Up-regulation of PTTG and b-FGF expression may be involved in the progression of acute leukemia and correlated closely with therapeutic effect. Associated detection of PTTG and b-FGF may help to judge the malignancy degree and prognosis of acute leukemia.
