Objective: To elucidate the effect of sulfur fumigation on the content of chemical composition and quality of Panacis Quinquefolii Radix, and to discuss the identification method of sulfur fumigated Panacis Quinquefolii Radix. Method: The content changes of ginsenoside Rb₁, Re, Rg₁ in Panacis Quinquefolii Radix were determined by HPLC-DAD before and after sulfur fumigation. The content changes of 11 inorganic elements in Panacis Quinquefolii Radix before and after sulfur fumigation were detected by microwave digestion method and inductively coupled plasma emission spectrometry tandem mass spectrometry (ICP-MS). The quality difference of Panacis Quinquefolii Radix before and after sulfur fumigation was qualitatively distinguished combined with the principal component analysis. Result: Three ginsenosides were well separated and showed good linearity with R² ≥ 0.999.Before sulfur fumigation, the contents of ginsenoside Rg₁, Re and Rb₁ in Panacis Quinquefolii Radix were (0.897±0.045), (13.092±0.639), (12.896±0.430) g ·kg^-1, respectively. After sulfur fumigation, the contents of these three components in Panacis Quinquefolii Radix were (0.807±0.032), (11.968±0.627), (11.752±0.696) g ·kg^-1, respectively. After fumigation, the contents of inorganic elements (Cr, Mn, Co, Cu, As, Se, Ag, Cd, Sb, Pb and Fe) from Panacis Quinquefolii Radix increased in varying degrees. According to the distribution results of three-dimensional (3D) scattered points, sulfur and non-sulfur fumigation products of Panacis Quinquefolii Radix could be effectively distinguished. Conclusion: After sulfur fumigation, the contents of ginsenoside Re and Rb₁ in Panacis Quinquefolii Radix decrease significantly, but the contents of 11 inorganic elements increase, suggesting that sulfur fumigation may have a great influence on the quality of Panacis Quinquefolii Radix.

OBJECTIVETo compare the therapeutic effects of high-frequency oscillatory ventilation+pulmonary surfactant (HFOV+PS), conventional mechanical ventilation+pulmonary surfactant (CMV+PS), and conventional mechanical ventilation (CMV) alone for acute lung injury/acute respiratory distress syndrome (ALI/ARDS) in neonates.

METHODSA total of 136 neonates with ALI/ARDS were enrolled, among whom 73 had ALI and 63 had ARDS. They were divided into HFOV+PS group (n=45), CMV+PS group (n=53), and CMV group (n=38). The neonates in the first two groups were given PS at a dose of 70-100 mg/kg. The partial pressure of oxygen (PaO), partial pressure of carbon dioxide (PaCO), PaO/fraction of inspired oxygen (FiO), oxygenation index (OI), and respiratory index (RI) were measured at 0, 12, 24, 48, and 72 hours of mechanical ventilation.

RESULTSAt 12, 24, and 48 hours of mechanical ventilation, the HFOV+PS group had higher PaOand lower PaCOthan the CMV+PS and CMV groups (P<0.05). At 12, 24, 48, and 72 hours of mechanical ventilation, the HFOV+PS group had higher PaO/FiOand lower OI and RI than the CMV+PS and CMV groups (P<0.05). The HFOV+PS group had shorter durations of mechanical ventilation and oxygen use than the CMV+PS and CMV groups (P<0.05). There were no significant differences in the incidence rates of air leakage and intracranial hemorrhage and cure rate between the three groups.

CONCLUSIONSIn neonates with ALI/ARDS, HFOV combined with PS can improve pulmonary function more effectively and shorten the durations of mechanical ventilation and oxygen use compared with CMV+PS and CMV alone. It does not increase the incidence of complications.

Objective To investigate the relationship between peripheral blood mtDNA content and acute coronary syndrome. Methods A total of 244 patients who received coronary angiography(CAG)was enrolled in this study. They were divided into acute coronary syndrome(ACS)group(n=183)and control group(n=61)ac-cording to the CAG results. A quantitative real-time PCR-based method was used to measure relative content of mtDNA in peripheral blood. According to lesion blood vessel counts ,ACS patients were divided into single lesion group,double lesion group and three lesions group. Gensini score was used to quantitatively evaluate the severity of coronary stenotic lesions. Then we analyzed the relationship of mitochondrial DNA content with the lesion counts and the Gensini score. Results The ACS group had a lower mtDNA content ,as compared to controls (P <0.001).The lesion blood vessel count and mtDNA content in the single ,double and three vascular lesions group were all significanlty lower than that of the control group(P<0.05)and that of the double,three vascular lesions group were both significantly lower than that of the single vascular lesion group(P<0.05). According to the Gensi-ni score,all patients were divided into four groups,where with mtDNA content was decreased with the increase of the Gensini score(P < 0.01). The linear regression analysis showed that Gensini score was negatively correlated with mtDNA content(r=-0.644,P<0.001). ROC curve analysis showed that the area under the curve of mtDNA content for ACS diagnosis was 0.855(P<0.001),with the sensitivity and specificity of 0.756 and 0.833,respec-tively. Conclusion MtDNA content is closely associated with ACS and the Gensini score ,the latter indicating the severity of coronary stenotic lesions. MtDNA content detection has its value in the diagnosis of ACS.

Objective To understand the detection rate of hashimoto's thyroiditis (HT) and the occurrence of abnormal thyroid function in medical examination population in Huanghua City,Hebei Province.Methods Using the retrospective analysis method,the thyroid examination data of residents of Huanghua City who were examined in the Cangzhou Hospital of Traditional Chinese and Western Medicine in Hebei Province from 2014 to 2016 were collected,the detection rate of HT and the occurrence of abnormal thyroid function were analyzed.Results A total of 4 413 people were examined,aged (45.76 ± 10.13) years old;including 2 099 males and 2 314 females.The HT detection rate of the medical examination population in Huanghua City was 6.55％ (289/4 413),and there was a trend of increasing year by year (x2trend =7.126,P ＜ 0.05).The difference in HT detection rates between different genders (male:2.86％,famale:9.90％) was statistically significant (x2 =89.077,P ＜ 0.05);there was a statistically significant difference in the HT detection rates among women of different age groups (x2 =18.541,P ＜ 0.05),and there was no significant difference in the detection rates of HT among men of different age groups (x2 =8.424,P ＞ 0.05).The incidence of abnormal thyroid function in HT patients was 25.61％ (74/289),of which the highest detection rate was 34.74％ (33/95) in the 40-＜ 50 years old group;the detection rates of HT with hyperthyroidism,hypothyroidism and subclinical hypothyroidism were 3.11％ (9/289),6.57％ (19/289) and 15.92％ (46/289),respectively.The detection rate of HT with subclinical hypothyroidism was higher.Conclusions The HT detection rate of the population in Huanghua City has increased year by year,and some HT patients are associated with abnormal thyroid function,and their detection rate of HT with subclinical hypothyroidism is the highest.Early diagnosis of HT should be strengthened,and appropriate prevention and treatment measures should be taken in time to reduce the occurrence of HT with abnormal thyroid function.
