Objective To study the effects of rehabilitation(RT)on cardiac function in cerebral infarct (CIF)patients with cardiac insufficiency(CIS).Methods Fifty-nine CIF patients with CIS were randomly divid- ed into a treatment group(T group,n=29)and a control group(n=30),and all patients were treated with routine pharmacotherapy for 2 months.In addition,RT was administrated in the T group at the same time.The grading of the New York Heart Association(NYHA)and the changes in cardiac function associated index were observed in both groups before and after treatment.Results Compared with the control group,NYHA grades,left ventricle ejection fraction(LVEF),the levels of brain natriuretic peptide(BNP)in the blood plasma,and the 6min walking range of the T group patients were all significantly improved after treatment(P＜0.05).Conclusion RT can improve car- diac function in CIF patients with CIS.

Objective To analyze the impact of multiple factors on the incidence of pneumothorax associated with CT-guided transthoracic needle aspiration biopsy.Methods The sign of pneumothorax after 162 cases(lesion diameter from 1cm to 6cm)CT-guided transthoracic needle aspiration biopsy was observed and its relationship with multivariate factors were analyzed by multivariate logistic regression model.Results Thirty-two cases presented pneumothorax accounting for 19.8%.Single variate analysis showed that the sign of pneumothorax ralated to intercurrent COPD,distance from lesion and chest wall,needle dwelling time and lesion diameter.67 patients of intercurrent COPD with postoperative pneumothorax occurred in 22 cases (32.8%);With respect to those having lesions close to the chest wall(48 cases),and the cases with the distance between the chest wall and lesions less than 2cm(55 cases)and greater than 2cm(59 cases), the postoperative pneumothorax occurred in 0,14(25.5%),18(30.5%)cases respectively;For those patients with needle in the chest residence time of less than 10 minutes(82 cases),10—20 minutes (51 cases),more than 20 minutes(28 cases)after the occurrence of pneumothorax were 8(9.6%), 10(19.6%),14(50%)cases respectively;In contrast,those with lesion diameter less than 2 cm (65 cases),2—4cm(52 cases),more than 4cm(45 cases)were 19(29.2%),8(15.4%) and 5(11.1%)respectively.The multivariate logistic regression analysis showed that the prior three factors were risk factors of pneumothorax(OR=4.652,4.030,2.855 respectively).Conclusions To avoid the pneumothorax,caution must be taken with respect to CT-guided transthoracic needle aspiration biopsy, patients with intercurrent COPD,long distance between lesion and chest wall,and smaller lesion diameter. For operation the needle dwell time within thorax should be minimized.

OBJECTIVETo investigate the effect of allogeneic leukocyte immunization combined with in vitro fertilization-embryo transfer (IVF-ET) for treatment of infertility induced by habitual abortion.

METHODSAllogeneic leukocyte immunization was performed in 9 patients with infertility induced by habitual abortion, with another 9 patients undergoing IVF-ET without habitual abortion as the control group. All the patients were treated with long GnRH-a protocols. The infertility patients with recurrent spontaneous abortion history were immunized with lymphocytes from the husband for before IVF-ET and after clinical pregnancy.

RESULTSThe fertilization rates of the immunotherapy group and control group were 81.3% and 82.2%, respectively, showing no significant difference (P>0.05). Five patients in each group had clinical pregnancy, and a twin pregnancy occurred in the control group. The embryo implantation rates were also comparable between the two groups (22.7% vs 28.6%, P>0.05). All the fetuses resulted from IVF-ET developed normally and were healthily delivered.

CONCLUSIONAllogeneic leukocyte immunotherapy along with IVF-ET is effective for treatment of infertility resulting from recurrent spontaneous abortion.

OBJECTIVETo investigate the effects of electromagnetic radiation on the physiological indices and immune function of operators.

METHODSThe general conditions and electromagnetic radiation awareness rate of 205 operators under electromagnetic radiation were evaluated using a self-designed questionnaire. Physical examination, electrocardiography, and routine urine test were performed in these operators. Peripheral blood was collected from the operators under electromagnetic radiation for blood cell counting and biochemical testing, and their peripheral blood lymphocytes were cultured for determination of chromosomal aberrant frequency and micronucleus frequency. The data from these operators (exposure group) were compared with those of 95 ordinary individuals (control group).

RESULTSThe chief complaint of giddiness, tiredness, dizziness, and amnesia showed significant differences between the exposure group and control group (P < 0.01), and the difference in headache became larger with an increase in working years. The awareness rate of electromagnetic radiation damage was significantly higher in the exposure group than in the control group. The difference in bradycardia was significant between the two groups (P <0.01), and the incidence was higher with longer working years. Significant differences between the two groups were also found in the numbers of individuals with elevated alanine aminotransferase, total bilirubin, and direct bilirubin (P < 0.01), populations with increased lymphocyte ratio and decreased neutrophil ratio (P < 0.01), populations with positive occult blood, urobilinogen, and bilirubin tests, and the number of individuals with increased micronucleus frequency of cultured peripheral blood lymphocytes (P < 0.01). In addition, the exposure group had significantly increased complement C3 and C4 (P < 0.01), significantly increased IgG (P < 0.05), and significantly decreased IgM (P < 0.01), as compared with the control group.

CONCLUSIONElectromagnetic radiation may lead to the changes in physiological indices, genetic effects, and immune function and affect the health and immune function in operators. The adverse effects are increased as the working years increase. So it is important to strengthen occupational protection of operators under electromagnetic radiation.

OBJECTIVETo study clinical features, treatment and curative effects in children with acute clenbuterol poisoning, in order to provide a basis for early diagnosis and treatment.

METHODSClinical data of 28 hospitalized children with acute clenbuterol poisoning in April 2011 were retrospectively studied.

RESULTSOf the 28 patients, there were 15 males and 13 females, aged 1 to 13 years (mean age 6.5±4.8 years). Vomiting, palpitations and limb shaking were found as main clinical manifestations in the patients. Main changes of blood biochemical included hypokalemia, lactic acidosis, hyperglycemia, hypsocreatinkinase. Snus tachycardia and S-T segment depression were observed on ECG. Patients' symptoms were gradually alleviated after 12-78 hours by use of beta blockers, potassium supplement, protecting the heart and other symptomatic and supportive treatment. Blood biochemical indexes were improved after 48 hours of admission. All of the patients were cured after 5 days. The symptoms of the patients do not longer occur during a follow up of half a month.

CONCLUSIONSAcute clenbuterol poisoning is characterized by vomiting, palpitations, limb shaking, hypokalemia, lactic acidosis and tachycardia in children. An early effective treatment of this disease can improve prognosis in children.

OBJECTIVETo investigate the causes of unintentional injuries in children and to provide reference for reducing the incidence of unintentional injuries in children.

METHODSA retrospective analysis was performed on the clinical data of 924 children with unintentional injuries who were hospitalized in Zhongshan Boai Hospital from January 2008 to December 2010.

RESULTSOf the 924 cases, 26.4% suffered falls, which was the most common cause of injuries, 15.7% suffered burns and scalds, 14.0% were injured by foreign bodies, and 13.1% were injured in traffic accidents. Unintentional injuries occurred mainly among children aged 0-3 years (67%). The proportion of cases in summer (July to September) was significantly higher than in any other season (P < 0.05), and burns were the common causes of injuries in summer. Home was the most common place where unintentional injuries occurred (36.9%). The incidence of traffic accidents was significantly higher in non-local children than in local children (P < 0.001). As for the parents' educational levels, the children whose parents had an education level below junior middle school accounted for the highest proportion of all cases of unintentional injury (45.5%). Injuried cases in rural areas accounted for a significantly higher percentage than in urban areas (P < 0.05).

CONCLUSIONSFalls are the principal cause of unintentional injuries in children. Young children (0-3 years) are most vulnerable to unintentional injuries. Unintentional injuries mostly occur at home. The incidence of traffic accidents is higher in non-local children than in local children. Parents' education levels are associated with the incidence of unintentional injuries. In order to reduce the incidence of unintentional injuries in children, preventive measures must be carried out, and safety education should be enhanced in consideration of children's age, sex and family background.

This study was aimed to investigate the expression characteristics of two transcriptional factors in Ikaros family, Ikaros and Helios isoforms and their mechanism, as well as their correlation with clinical parameters, which play important roles in transcriptional regulation of hematopoiesis. Expression of Ikaros and Helios isoforms in a total of 163 patients with leukemia and correlations between Ikaros and Helios isoforms were analyzed by PCR. The results showed that different expression patters of Ikaros and Helios isoforms existed in leukemia patients, that is, Ikaros isoform (Ik-6) was predominantly expressed in acute lymphoblastic leukemia (ALL) with BCR/ABL fusion gene, while Helios isoform (He-i) was overexpressed in T-cell ALL patients. The results of cloning and sequencing demonstrated that the isoforms of Ikaros and Helios had different genetic alterations. The statistical correlation between these two isoforms not was found in this study, although interaction between Ikaros and Helios has been reported. It is concluded that although Ikaros and Helios belong to the same family with similar structure of zinc fingers, their isoforms have different expression profile, specific genetic alterations, and different clinical relevance in patients with leukemia. The connection and interaction between Ik-6 and He-i needs further research.

To investigate the cell-killing effect and its possible mechanism of rClone30-hDR5 in combination with TRAIL on human hepatic carcinoma (HCC) cell line, first of all, recombinant plasmid pee12.4-hDR5 was introduced into HepG2 cells by liposome transfection. After five rounds of screening by flow cytometry, HepG2 cells expressing high levels of DR5 on cell surface were isolated. The cytotoxicity of TRAIL to selected cells was higher than that of TRAIL to HepG2 cells by MTT method (P < 0.01). The result suggested that the cloned hDR5 gene had biological activity. MTT assay showed that, rClone30- hDR5 in combination with TRAIL more efficiently inhibited the tumor growth of HepG2 cells compared to rClone30-hDR5 or TRAIL in vitro. The results of Annexin V-FITC/PI staining and Quantitative Real-time PCR indicated that rClone30-hDR5 in combination with TRAIL significantly increased the mRNA levels of caspase 3 and caspase 8, and induced the apoptosis of tumor cells. HepG2 cells were infected with rClone30-hDR5 or rClone30 at MOI of 1. The expression of hDR5 on tumor surface increased significantly by rClone30-hDR5 compared to that by rClone30, which contributed to the sensitivity to TRAIL. In conclusion, rClone30-hDR5 in combination with TRAIL has potential application value in cancer treatment.
