Objective: To investigate the use of new types of drugs among HIV/AIDS patients in Ningbo City, Zhejiang Province, so as to provide insights into surveillance and interventions for use of new types of drugs among HIV/AIDS patients. Methods: The HIV/AIDS patients in Ningbo City were randomly sampled from the HIV/AIDS Prevention and Control Information System of Chinese Disease Prevention and Control Information System. Patients' demographics, use of new types of drugs and sexual behaviors were collected using questionnaire surveys. Patients' hair samples were collected, and new types of drugs were determined in hair using liquid chromatography-mass spectrometry (LC-MS). In addition, factors affecting the use of new types of drugs were identified using a multivariable logistic regression model. Results: A total of 254 HIV/AIDS patients were enrolled, including 214 men (84.25%), 31 cases aged under 25 years (12.20%), 66 cases aged 25 to 30 years (25.98%), and 157 cases aged 31 to 75 years (61.81%). There were 30 cases reported previous use of new drugs (11.81%), including 27 cases reported previous use of methamphetamine (90.00%). There were 48 cases tested positive of new types of drugs, with a positive rate of 18.90%, including 44 cases tested positive for methamphetamine (91.67%). Multivariable logistic regression analysis identified age (25 to 30 years, OR=6.926, 95%CI: 1.412-33.969), occupation (students/teachers/cadres/employees/retirees, OR=6.971, 95%CI: 2.123-22.889; housekeeping and housework servants/unemployed, OR=3.356, 95%CI: 1.289-8.739; business/public place servants, OR=2.447, 95%CI: 1.033-4.448) and syphilis infection during recent six months (OR=3.491, 95%CI: 1.664-7.326) as factors affecting the use of new types drugs among HIV/AIDS patients. Conclusions The use of new types of drugs exists in HIV/AIDS patients in Ningbo City. Age, occupation and syphilis infection were associated with the use of new types of drugs among HIV/AIDS patients.

Objective To investigate the value of two-dimensional speckle tracking imaging (STI) in assessing regional myocardial dysfunction and myocardial fibrosis in a mouse model of myocardial infarction.Methods Twenty C57/B6 mice were randomly divided into two groups:myocardial infarction (MI) group (n =10) and sham-operation (SO) group (n =10).Echocardiography was performed four weeks after surgery.High frame rate two dimensional images were recorded in the left ventricular short axis views at the papillary muscle level and analysised at EchoPac workstation.Peak radical strain (PRS) and peak radical strain rate (PRSR) of each segment were measured at systolic period.Percent segmental fibrosis (PSF) was assessed from histological left ventricular cross sections stained by Masson trichrome.Results Compared with SO group,PRS and PRSR decreased significantly in all segments of MI group (P ＜ 0.01),especially in anterosepetal,anterior and lateral segments (P ＜0.05).PSF of anterosepetal,anterior,lateral and posterior segments in MI group increased significantly than those in SO group(P ＜0.01),and were negatively correlated with PRS and PRSR of these segments(r =-0.88,P ＜0.001 ; r =-0.77,P ＜0.001).Conclusions STI could accurately quantify regional myocardial function in a mouse model of myocardial infarction.Segmental radial strain and strain rate measured by STI were significantly correlated with PSF,which can be a non-invasive tool for monitoring myocardial fibrosis after myocardial infarction.

OBJECTIVETo systematically assess the efficacy and safety of Rhodiola in treating chronic stable angina pectoris.

METHODSOur group searched the Cochrane library, PubMed, Embase, Chinese biomedical literature database (CBM), VIP database (VIP), Chinese Journal Full-text Database (CNKI) for the literature published in English and Chinese till April 2013. Randomized controlled trials (RCTs) were included on the therapeutic effect of Rhodiola or Rhodiola plus conventional Western medicine in comparison with the conventional Western medicine treatment on stable angina. Data were extracted according the data extraction form. The literature methodological quality was assessed by using the Cochrane handbook, and data analyzed by Rev-Man 5.2 Software for Meta-analysis. The effect indicators of outcomes was expressed by odds ratio (OR) and 95% CI.

RESULTSA total of 7 randomized controlled trials, 662 cases of stable angina pectoris patients met the inclusion criteria and all published in Chinese, without one scientific design and high quality literature. Compared with the conventional Western medicine treatment, combined with oral administration of Rhodiola could improve the efficiency of anti-angina (OR = 2.49, 95% CI: 1.02 - 6.09). Combined with intravenous infusion of Rhodiola could also improve the efficacy of angina pectoris (OR = 4.86, 95% CI: 2.4 - 9.82). Oral administration of Rhodiola couldn't improve ECG efficacy (OR = 1.25, 95% CI: 0.67 - 2.34). Intravenous infusion of Rhodiola could improve the clinical efficacy (OR = 2.94, 95% CI: 1.61 - 5.35). Combined with the conventional treatment, intravenous infusion of Rhodiola could improve the whole blood viscosity (low and high shear rates) and inverse variance (IV) (-1.36 and -0.99, 95% CI: -1.65 - 1.07 and -1.26 - 0.71), but could not reduce serum fibrinogen and D-dimer level. The incidence rate of adverse reactions was higher than that of the conventional treatment combined with Rhodiola (OR = 0.1, 95% CI: 0.02 - 0.51).

CONCLUSIONSOn the basis of routine treatment, Rhodiola could further improve patients' symptoms. Combined with intravenous medication, Rhodiola could increase the ECG improvement rate, and reduce adverse reactions. But the methodological quality of included studies was poor, the number of samples was small, and influence factors such as the intervention period was short. This conclusion needs scientific and rational design in a larger sample, multicenter clinical trial to verify.

OBJECTIVETo analyze the clinicopathological features and prognosis of colorectal cancer patients with preoperative cancer-related anemia.

METHODSClinical data of 354 patients with colorectal cancer in the Second Affiliated Hospital of Guangzhou Medical College from January 2003 to July 2009 were analyzed retrospectively. Those with hemoglobin(Hb)<120 g/L before surgery were defined as cancer-related anemia.

RESULTSOf the 354 colorectal cancer cases, 195 were males and 159 were females. The median age was 65(range 22-92) years. Preoperative cancer-related anemia tended to be occurred in female(P<0.01) and those with preoperative albumin ≤35 g/L (P<0.01), right colon cancer(P<0.01) and full-thickness invasion(P<0.05). Cox regression analysis showed preoperative cancer-related anemia was an independent unfavorable factor for overall survival (HR=1.60, 95% CI:1.05-2.44; P<0.05), but not for disease-free survival (HR=1.43, 95% CI:0.97-2.12; P>0.05) in colorectal cancer.

CONCLUSIONSPreoperative cancer-related anemia plays an important role in the development and prognosis of colorectal cancer and great attention should be paid to clinical practice.

OBJECTIVETo investigate the effects and mechanisms of high glucose on the phenotype transformation of rat vascular smooth muscle cells (VSMCs).

METHODSVSMCs ere isolated from rat thoracic aorta and the 3rd-5th VSMCs were incubated with normal glucose (5.5 mmol/L), high glucose (25 mmol/L), or high glucose (25 mmol/L) + P38 inhibitor (25 mmol/L +SB203580) for another 24 hours. Then the gene expression of osteopontin (OPN), alpha smooth-actin (alpha-SMA), matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9(MMP-9) were assayed by real time RT-PCR, the protein expression of P38 were assayed by Western blot.

RESULTS(1) High glucose promoted the phenotype transformation of VSMCs and up-regulated the expression of MMP-2 and MMP-9. (2) High glucose promoted the phosphorylation of P38. (3) SB203580, the inhibitor of P38/MAPK signal pathway, inhibited the effects of high glucose on phenotype transformation and expression of MMP-2 and MMP-9.

CONCLUSIONHigh glucose may promote phenotype transformation of VSMCs via the signal pathway of P38/MAPK.

As the lymphocytes of immuno-mediated aplastic anemia (IMAA) are in active state, and the hematopoietic stem cells are in silence, this study was aimed to design a new strategy to treat IMAA. To utilize the difference of radiosensitivity between active lymphocytes and silent hematopoietic stem cells, the animals suffered from IMAA were treated with a single low dose of irradiation, killing the active lymphocytes to release its suppression to hematopoietic stem cells without injuring the hematopoietic stem cells. Therefore, the hematopoiesis can be restored. Experiments were completed in IMAA mouse model. At day 4 after making IMAA, the model mice were giren total body irradiation of 150 cGy, the non-treated model mice and normal mice irradiated with 150 cGy were used as control. The survive time and survive rate of mice, blood picture, the account of nucleated cell of bone marrow, and pathological changes of bone marrow and lymphoid tissues of each group mice were observed. The results were as follows: (1) Survive rate of IMAA mice in non-treated group was 12.5%, the average survive time was 27.4 +/- 13.4 days. 100% of IMAA mice in irradiation-treated group survived over 60 days. The mice of irradiation control group all survived. (2) The account of WBC of IMAA mice in non-treated group dramatically decreased until to die, and in the irradiation-treated group it was gradually increased since the 10th day after treatment and close to normal level at the 28th day. (3) The RBC hematocrit of IMAA mice in non-treated group progressively decreased at day 14, and IMAA mice of irradiation-treated group gradually recovered closely to normal level after slightly fall at day 14, similar to the mice of irradiation control group. (4) The account of nucleated cells of bone marrow in non-treated IMAA mice dramatically decreased, and in the IMAA mice of the irradiation-treated group it was rapidly increased following transient fall, and restored to normal. (5) Pathological observations showed that the bone marrow and spleen of non-treated IMAA mice demonstrated typical aplastic anemia pattern, including bone marrow failure, marked splenatrophy, but the bone marrow and lymphoid tissues in the IMAA mice of irradiation-treated group were recovered to normal at day 28 after treatment. It is concluded that the low dose of irradiation displayed a significant therapeutic effect to IMAA mice, their hematopoisis could be completely restored to normal. The mechanism of therapeutic effect may contribute to low dose of irradiation killing the immunocompetent lymphocytes, therefore, suppressing hematopoiesis. The experiment results not only set up a new strategy for IMAA treatment, but also provided a clue to study the mechanism of IMAA.
