Objective:To explore the application value of dynamic monitoring of serum soluble interleukin-2 receptor (sIL-2R) and stromal cell-derived factor 1 α (SDF-1α) in patients with acute leukemia (AL).Methods:A total of 187 patients with AL admitted to the Second Hospital of Shanxi Medical University from March 2017 to August 2018 were selected and 90 healthy subjects at the same period were selected as the healthy controls. The levels of serum sIL-2R and SDF-1α were detected at the initial diagnosis, remission phase and relapse phase, respectively. The clinical value of dynamic monitoring of sIL-2R and SDF-1α was analyzed.Results:Among 187 patients with AL, 135 patients (72.19%) had complete remission (CR) after chemotherapy, 52 patients (27.81%) had partial remission, and 43 patients (31.85%) relapsed. The level of serum sIL-2R at the AL initial diagnosis period was (533±32) U/ml, which was higher than that in the healthy controls [(247±30) U/ml], and the difference was statistically significant ( t = 71.976, P < 0.01); the level of serum SDF-1α at the AL initial diagnosis was (2 968±305) pg/ml, which was higher than that in the healthy controls [(1 358±160) pg/ml], and the difference was statistically significant ( t = 47.043, P < 0.01). The levels of serum sIL-2R [(308±30) U/ml] and SDF-1α [(1 576±184) pg/ml] in the CR phase were lower than those in the initial diagnosis of patients with AL; and the levels of sIL-2R [(599±36) U/ml] and SDF-1α [(2 894±301) pg/ml] in the relapse phase were higher than those in the CR phase of patients with AL (all P < 0.01). Conclusions:The levels of serum sIL-2R and SDF-1α in patients with AL are increased, and there are big differences in the levels of sIL-2R and SDF-1α at the initial diagnosis, remission phase, and relapse phase. Dynamic monitoring of both can provide the data support for early clinical intervention.

Study on the effects of different vitamin A levels on thyroid cell apoptosis and related gene expression of mice taking excessive iodine / 中国地方病学杂志

Objective To explore the effects of different vitamin A(VA) levels on thyroid cells apoptosis and its gene expression of mice taking excessive iodine. Methods Kunming mice were randomly divided into 6 groups according to body weight 3 weeks after born: normal control(NI) group, high iodine(HI) group, low vitamin (LVA) group, high iodine plus low vitamin A(HI+LVA) group, high iodine plus vitamin A1 (HI+VA1) group, high iodine plus vitamin A2(HI+VA2) group. The VA was given in food(4000,4000,0,0,8000,16 000 U/kg), and the iodine was given as potassium iodate in water (I-:50,3000,50,3000,3000,3000 μg/L). The apoptosis was tested using in situ end labehng(TUNEL) method. Reverse transcription polymerase chain reaction (RT-PCR) were used to measure the level of mRNA of apoptosis gene(Fas, FasL, Bcl-2) in tissues. Results Apoptotic index measured by TUNEL method was rising along with the mice age. Compared to NI group[(14.09±5.68)%], apoptotic index was significantly increased in HI[(20.91±9.57)%], HI+LVA[(20.29±9.90)%]and HI+VA2 [(19.51±8.25)%]groups in the three months(P < 0.05). Compared to NI group[(16.80±9.90)%], apoptotic index was significantly increased(P < 0.05) in HI[(23.22±8.58)%],LVA[(22.56±6.17)%],HI+LVA [(25.99±9.62)%],HI+VA1 [(21.65±7.74)%]groups in the six months. Compared with the NI group(Fas: 1.29±0.25,1.27±0.26; FasL: 1.60±0.13,1.65±0.13), the mRNA levels of Fas and FasL in HI group(Fas: 1.57±0.36,1.49±0.35; FasL: 1.85±0.46,1.84±0.32) were increased, but the differences were not remarkable(P > 0.05) in the three and six months. Compared with the HI group, the mRNA levels of Fas in HI+ VA1, HI+VA2(1.33±0.35, 1.30±0.26) groups were decreased to the level in NI group in the six months. The mRNA levels of Fas and FasL were not different (P > 0.05) between HI+LVA(I.60±0.27,1.88±0.46) and HI groups in the three months. The mRNA levels of Bcl-2 were not remarkably differences in the three months (1.05±0.19,0.96±0.33,0.95±0.26,1.18±0.27,1.10±0.19,0.98±0.36, all P > 0.05), and in the six months (1.35±0.28,1.60±0.25,1.48±0.18,1.71±0.26,1.66±0.29,1.56±0.35, all P > 0.05). Conclusions Excessive iodine can cause thyroid cells apoptosis in mice. Supplementation of suitable amount of VA can regulate the levels of the apoptosis-related genes expression, and partly antagonize the apoptosis caused by high iodine.

The effect of fluid shear stress on the NO synthesis of rat osteoblast-like cells / 生物医学工程学杂志

This study sought to elucidate the function of NO during the signal transduction wherein fluid shear stress regulates the proliferation and differentiation of osteoblast cells. The isolated rat osteoblast-like cells were exposed to fluid shear stress 12 dyn/cm2 for 5, 10, 15, 30, 60 and 120 min respectively with the use of a flow chamber. The NO release was examined. After the exposure to fluid shear stress, the NO synthesis of rat primary osteoblast-like cells increased significantly (P<0.05) when compared with the control. After 60 minutes of exposure, the release of NO began to increase significantly (P<0.05), but no significant increase as such was seen in the control (P>0.05). NO synthesis may be one of the signal transduction pathways which transduce the fluid shear stress into osteoblast cells. In early stage, it may be induced by cNOS and in late stage by iNOS.
