Chinese Journal of cardiovascular Rehabilitation Medicine 2014;23(3):292-294
Objective:To compare the level of low density lipoprotein cholesterol (LDL-C)before and after treat-ment between Uygur and Kazak nationality patients diagnosed as coronary heart disease (CHD).Methods:A total of 191 Uygur nationality patients and 184 Kazak nationality patients,who received coronary angiography and were diagnosed as CHD first time, and received measurement of LDL-C concentration.They received CHD secondary preventive treatment for 8~12 months,LDL-C concentration was measured again after treatment,and it's com-pared and analyzed between two nationalities.Results:After treatment,there were significant reductions in levels of total cholesterol (TC)and LDL-C in Uygur and Kazak nationality CHD patients.Compared with Kazak nationality pa-tients,there were significant reductions in levels of LDL-C [(2.74±0.13)mmol/L vs.(2.21±0.17)mmol/L]in Uygur nationality CHD patients (t=3.141,P<0.01).Conclusion:Effect lowering in Uygur nationality patients with coronary heart disease ,especially low density lipoprotein cholesterol is better than that of Kazak nationality.

Objective To verify whether the X brand air purifier could adsorb the formaldehyde in indoor air. Method An purifying test was carried out in a purified laboratory that had a volume of 30 m3, with an air leakage rate less than 0.05 m3/h, and was equipped with medium and high effective filters, air circulating ventilation system, gas sample generating system,etc. Results Significanly negative correlation was observed between the values of natural logarithm of formaldehyde concentration (lnCt) and time variables with a correlation coefficient r values of-0.995 0 ~-0.999 7. After the running of the air purifiers, the concentrations of formaldehyde in air significantly decreased with the prolongation of the running duration of air purifiers compared with its original concentration (P0.05). Conclusion This kind of air purifier could effectively adsorb formaldehyde in indoor air.

Objective: By high performance liquid chromatography determination of metronidazole content of different sterilization parameters metronidazole injection, selection of the optimal sterilization parameters. Methods: The Agilent Extend-C18 analytical column (250 mm×4.6 mm, 5μm) was adopted with the mobile phase of water:Alcohol (80:20) at a flow rate of 1.5 mL/min; The column temperature was at 30℃; The detection wavelength was at 320 nm, 121℃ 15 min, the content of effective components metronidazole injection in 115℃ 30 min sterilization parameters. Results:The average content of metronidazole determination before sterilization liquid is divided into 101.57%, with excessive killing sterilization after liquid content is 101.47%, determined by the probability of survival after sterilization liquid content of 101.60%. The content of active component of different sterilization parameters of metronidazole and before sterilization contrast difference. Conclusion: The method is fast rapid, convenient, in accordance with the level of risk decision trees screened Metronidazole injection sterilization using terminal over kill sterilization accurate and can be used for the metronidazole in metronidazole injection.

Objective To study the prognosis of neonatal hyperthyrotropinemia (HT). Methods Children with HT were followed up regularly to evaluate the growth index, thyroid function and effectiveness of treatment. Results One hundred and ninety-one neonates with serum TSH level of 5.6~10 mU/L at the screening were followed up until 24 months old. Serum TSH gradually returned to normal range in 182 cases. Serum TSH increased to be>10 mU/L in 5 cases who were treated with levothy-roxine sodium. Serum TSH lfuctuated between 5.6 and 10 mU/L in 4 cases who were continually followed up. Among 44 cases of serum TSH at 10~20mU/L, serum TSH gradually returned to normal range after levothyroxine sodium treatment in 38 cases;se-rum TSH increased to>20 mU/L in 7 cases for whom continuous treatment with levothyroxine sodium was required. In 242 cases of HT neonates, 18 cases had received continuous levothyroxine sodium replacement treatment for 2 years and were followed-up continuously. Conclusions Most of the newborns with HT recover within 2 years, while a few develop thyroid dysfunction and require follow-ups.

Objective To study the correlation between serum homocysteine (Hcy) levels and chronic heart failure (CHF) with ultrasound cardiac function patients.Methods The subjects were 88 cases of CHF (CHF group) in our hospital between April 2014 to June 2015 between patients,selected 65 cases of healthy people as a control group over the same period in our hospital,using color Doppler ultrasound measurement of two groups patients of the left ventricular ejection fraction of patients groups (LVEF) and left ventricular end-diastolic diameter (LVEDd),and compared serum Hcy and NT-proBNP levels,LVEF and LVEDd in different NYHA classification patients,analysis of serum Hcy and NT-proBNP levels and LVEF,LVEDd between correlation of serum Hcy levels on cardiovascular incident.Results CHF group of the Hcy,NT-proBNP levels and LVEDd were significantly higher than control group (P < 0.01),LVEF was significantly lower than the control group (t =31.78,P =0.00);different NYHA functional class (Ⅱ ~ Ⅳ level) of Hcy,NT-proBNP,LVEDd and LVEF compared were statistically difference (P < 0.01);Pearson correlation analysis showed,CHF patients with LVEF serum Hcy levels were negatively correlated (r2 =0.974,P < 0.01),with LVEDd was positively correlated (r2 =0.896,P < 0.05),and higher serum Hcy levels,the higher the rate of cardiovascular happened in patients with CHF.Conclusion The serum Hcy and NT-proBNP levels in patients with CHF were significantly higher than healthy,and with the deterioration of heart function and increased while the LVEF was negatively correlated positively with LVEDd,cardiovascular events in high Hcy levels may also increase the incidence risk,so Hcy levels is expected as a new diagnostic marker CHF conditions change.
