Objective To observe the changes of systolic time interval after neonatal asphyxia and explore its relationship with clinical manifestation and prognosis. Methods Tow-dimensional and Doppler echocardiography were employed to detect tow - dimension parameters and left and right ventricular STI in 27 mild and 18 severe asphyxiated neonates as well as 14 normal controls and its relationship with clinical manifestation and prognosis was analyzed. Results There was no difference in cavity and thickness of heart and great arteries between normal and asphyxiated neonates. In acute stage mild and severe asphyxiated neonates had a shorter right ventricular ejection time (RVET) than normal neonates and a longer right ventricular prejection period (RPEP) was found in severe neonates than that in normal and mild asphyxiated neonates. Left ventricular preejection time (LPEP) was prolonged in comparison with normal neonates in acute stage and convalescence. There were more cases with increased RPEP/RVET in severe asphyxiaed group than those in mild and normal group in acute stage. The incidence of heart failure in acute stage and disability in late period was higher in cases with increased RPEP/RVET than that with normal RPEP/RVET. Conclusion Asphyxia has more severe damage to right ventricle than that to left ventricle. Cases with increased RPEP/RVET are prone to suffering from heart failure in acute stage and more likely to undergo disability in late period.

OBJECTIVETo explore the effect of Salvianolate on myosin heavy chain (MHC) in cardiomyocytes of congestive heart failure (CHF) rats.
METHODSSixty male SD rats were divided into 6 groups according to random digit table, i.e., the normal control group (NCG), the model group, the Captopril group (CAG), the low dose Salvianolate group (LSG), the high dose Salvianolate group (HSG), the Captopril and high dose Salvianolate group (CSG), 10 in each group. CHF rat model was established with peritoneal injection of adriamycin in all rats except those in the NCG. Equal volume of normal saline was peritoneally injected to rats in the NCG, once per week for 6 successive weeks. Corresponding medication was started from the 5th week of injecting adriamycin. Rats in the CAG were administered with Captopril solution at the daily dose of 10 mg/kg by gastrogavage. Rats in the LSG and the HSG were administered with Salvianolate solution at the daily dose of 24.219 mg/kg and 48.438 mg/kg respectively by gastrogavage. Salvianolate was dissolved in 2 mL 5% glucose solution and administered by peritoneal injection. Rats in the CSG were peritoneally injected with high dose Salvianolate solution and administered with Captopril solution by gastrogavage. Two mL normal saline was peritoneally injected to rats in the model group, once per day for 8 successive weeks. Eight weeks later, the cardiac function and myocardial hypertrophy indices were detected by biological signal collecting and processing system. mRNA expression levels of alpha-MHC and beta-MHC in cardiac muscle were detected by fluorescence quantitative PCR. Expressions of protein kinase C (PKC) in cardiac muscle were detected by Western blot.
RESULTSCompared with the normal control group, heart mass index (HMI) and left ventricular mass index (LVMI) obviously increased in the model group (P < 0.01). Compared with the model group, HMI and LVMI decreased in HSG, CAG, and CSG groups (P < 0.05, P < 0.01). It was more obviously lowered in the CSG group than in the CAG group (P < 0.05). Compared with the NCG, the mRNA expression level of alpha-MHC in cardiac muscle decreased, the mRNA expression level of p-MHC and the expression of PKC in cardiac muscle increased in the model group (P < 0.01). Compared with the model group, the mRNA expression level of alpha-MHC in cardiac muscle was increased, and the mRNA expression level of beta-MHC and the expression of PKC in cardiac muscle were decreased in HSG, CAG, and CSG groups (P < 0.05, P < 0.01). There was statistical difference between the CSG group and the CAG group (P < 0.05).
CONCLUSIONSSalvianolate could up-regulate the mRNA expression level of alpha-MHC, and down-regulate the mRNA expression level of beta-MHC in cardiac muscle. Its mechanism might be related to decreasing the expression of PKC.

There are few articles or reports collecting evidence about Kudiezi injection from premarketing and postmarketing research or studies systematically. This article is an exact miniature of a systematical report about Kudiezi injection. We analyzed information from four aspects, such as quality control reports, non-clinical premarketing safety experiments, postmarketing research (efficacy studies, hospital information system data and national spontaneous reporting system data), and literature analysis. All the four aspects build an evidence body for Kudiezi injection in order to inform its safety use in clinical practice and further study.

Objective To investigate the effects of donor-specific regulatory T cells (Treg) transfusion on islet allograft survival. Methods Allogeneic fresh islets from Balb/c mice were transplanted to streptozotocin-induced diabetic C57 mice. The survival of islet allografts was observed. The experiment was divided into 3 groups: control group, nothing had been done to the recipients; simple islet transplantation group, the recipients received the islet transplantation only; experimental group, the recipients were given 1 ×106 Treg, then received islet transplantation. Results Blood glucose (BG) was above 16. 7 mmol/L after islet transplantation in control group; In simple islet transplantation group,BG level returned to normal level 1 to 2 days after transplantation, and hyperglycemia appeared 7 to 11 days after transplantation and maintained as the same as that before transplantation; In experimental group, BG level returned to normal level 2 days after transplantation and maintained at a low level,and at the 21st day after transplantation BG level was over 16. 7mmol/L in some recipients. Islet allograft survival in experimental group was significantly prolonged as compared with simple islet transplantation group. Conclusion Donor-specific Treg transfusion could prolong the islet allograft survival,and maybe have positive effect on tolerance induction of islet transplantation.

Objective To estimate the impact of universal salt iodization on child intelligence quotient (IQ) development in Hainan province. Methods In this is a cross-section study from September in 2008 to April in 2009,the observation group was historical iodine deficiency ward which includes 2 counties and 6 townships,and the control group was non-historical ward which includes 6 counties and 9 townships. Comparison of child IQ distribution according to different geographical housing position(plain,mountainous area,coast),age and sex based on the result of urine iodine examination and the IQ test of children between 8 and 10 years old. Results The median of urinary iodine of children in the observation group was 196.2μg/L which was 2.13 times of the urinary iodine median in the control group(91.9μg/L). The average IQ of children in the observation group was 94.7 which was 8.5 higher than the control group(86.2) ; IQ≤69 rate in this group was 7.7%(91/1179),and it was 8.9 percentage point lower than the control group[16.6%(253/1520)]; IQ≥ 110 rate of the group was 18.3%(216/1179),and it was 10.0 percentage point higher than the control group[8.3%(126/1520)]. The average IQ of children living in mountainous area(83.1) was the lowest in the control group. It was 3.5 and 5.1 lower than that of the children living in the plain(86.6) and coastal area(88.2) respectively; the IQ≤69 rate of children living in mountainous area [20.5%(91/443)]was the highest,and it was 3.8 and 7.1 percentage point higher than that of the children living in the plain [16.7% (89/533)]and coastal areas [13.4% (73/544)]respectively. The average IQ of children aged 8 (97.4) was similar to those aged 9(95.9) in the observation group which was 6.8 and 5.3 higher than that of the children aged 10(90.6) in the same group respectively; However,the average IQ of children aged 8,9 and 10 was close in the control group(86.8,86.3 and 85.6). The average IQ of boys(96.2) was 3.1 higher than that of the girls(93.1),and their IQ≤69 rate[6.3%(37/590)]was 2.9 percentage point lower than that of the girls[9.2% (54/589)]in the observation group. On the other hand,the average IQ(87.2) of boys was 2.1 higher than that of the girls(85.1),and IQ≤69 rate[14.5%(114/787)]was 4.5 percentage point lower than that of the girls [19.0%(139/733)]in the control group. The average IQ of children with different housing geographical position,age and sex in observation group was 5.0-12.4 higher than that of the control group; their IQ≤69 rate was 7.7-13.2 percentage point lower than that of the control group; their IQ≥110 rate was 5.6-13.0 percentage point higher than that of the control group. Conclusions Supplementing salt iodization can improve child intelligence. Supplementing iodine can increase the child IQ and reduce the child mental retardation.
