OBJECTIVETo investigate the effect of Actinidia chinensis Planch polysaccharide (ACPS) on the growth and apoptosis of human gastric cancer SGC-7901 cells, and to explore the effect of SGC-7901 cells on p-p38 expression.

METHODSThe inhibition rates at different concentrations of ACPS on SGC-7901 cells at 24, 48, and 72 h were detected using CCK-8 method. Apoptosis ratios in SGC-7901 were determined by flow cytometry after 48-h treatment of different concentrations of ACPS. The expression of pro-caspase-9, PARP, and p-p38 in SGC-7901 cells after treated by different concentrations of ACPS was detected using Western blot. The expression of pro-caspase-9, PARP, and p-p38 was detected after SGC-7901 cells were pre-treated by p38 specific inhibitor.

RESULTSCompared with the control group, the optical density of SGC-7901 cells decreased after treated by 1, 2.5, 5, and 10 mg/mL ACPS (P < 0.05). Meanwhile, the longer the acting time, the lower the optic density (P < 0.01). IC50 was 7.43 mg/mL at 24 h; 3.88 mg/mL at 48 h, and 1.32 mg/mL at 72 h respectively. ACPS suppressed the protein expression of pro-caspase-9 (P < 0.01) and up-regulated the expression of PARP (89KD) (both P < 0.01). Further study showed that the protein expression of p-p38 was up-regulated in SGC-7901 cells treated by ACPS of different concentrations at 24 h (P < 0.05). The expression of phosphorylation p38 and the ACPS induced apoptosis of SGC-7901 cells could be inhibited after treated by specific inhibitor for 2 h.

CONCLUSIONSACPS could inhibit the growth of SGC-7901 cells and induce apoptosis. The underlying mechanism of inducing apoptosis was partially due to activating the p38MAPK path and further activating Caspase9 and PARP, finally leading to cell death.

Objective To discuss the pulmonary function change in infants with human bocavirus (HBoV) pneumonia or mycoplasma pneumonia (MP) and its clinical signiifcance. Methods One hundred and forty infants under 3 years old who were admitted due to pulmonary infection were recruited from January, 2013 to October, 2013. Among them, HBoV-DNA was detected in 64 cases, and MP-DNA was detected in 76 cases. Thirty eight normal age-matched infants were selected as controls. The shape of tidal breathing lfow-volume loops (TBFVLs) and change of every index were measured with a Pulmonary Testing System (Jaeger MasterScope). Results The ratio of time to peak tidal expiratory lfow (PTEF) to total expiratory time (TPTEF/TE), the ratio of VPTEF to expiratory volume (VPTEF/VE), tidal expiratory lfow at 25%of the remaining tidal volume (TEF25%) and the ratio of TEF25%to PTEF (25/PF) were signiifcantly decreased in infants with HBoV and MP infection as compared with healthy infants (P<0.05). However, there was no signiifcant difference of the above indices between infants with HBoV and MP infection (P>0.05). The shape of TBFVLs in infants with HBoV and MP pneumonia was changed and characterized by left-shifted PTEF and trough-like concave in descending limb. The PTEF was decreased in infants with pulmonary infection. Conclusions HBoV or MP infection results in impaired pulmonary function with manifestations of obstruction in small airway. The shape of TBFVLs in infants with HBoV and MP pneumonia is characterized by left-shifted PTEF and trough-like concave in descending limb.

OBJECTIVETo investigate the effect of baicalein on the gap junction intercellular communication (GJIC) in the TM4 Sertoli cells of the mouse testis and its related mechanism.

METHODSWe measured the cytotoxicity of different concentrations of baicalein on the TM4 Sertoli cells in the mouse testis by MTT, detected the fluorescence transfer of the TM4 Sertoli cells by parachute assay, and determined the expression of the protein connexin 43 ( Cx43) in the baicalein-treated cells by Western blot and immunofluorescence assay.

RESULTSBaicalein produced no obvious cytotoxicity on the TM4 Sertoli cells at the concentration below 60 µmol/L but significantly increased their GJIC at 0-20 µmol/L (P < 0.01). Western blot and immunofluorescence assay showed that 0-20 µmol/L baicalein remarkably elevated the expression of Cx43 in the TM4 cells (P < 0.01) and on the membrane of the TM4 cells.

CONCLUSIONBaicalein at the concentration of 0-20 µmol/L can significantly enhance GJIC in mouse TM4 Sertoli cells by increasing the expression of the Cx43 protein.

Objective To explore the predictive value of brain lobe location of stroke lesion to development of long-term post-stroke depression(PSD)in the first-episode ischemic stroke patients for providing evidence for early intervention.Methods In the prospective study,158 patients aged 60 and over with first-episode ischemic stroke were continuously admitted into Department of Neurology of Shangqiu First People's Hospital from January 2013 to July 2013.The 2 to 3 years follow-up after stroke episode was performed in 126 cases for inquiring into correlation between brain lobe location of stroke lesion and development of PSD.The diagnosis of depression was in accordance with Mental Disorders Diagnostic and Statistical Manual 4(DSM-Ⅳ)standard,and divided into groups of stroke with depression(n=52)and stroke without depression(n=74).The degree of depression was evaluated by 17-item Hamilton Rating Scale for Depression(HAMD17).The location,number and volume of stroke lesions were determined by head MRI.The relationship between PSD and pathogenetic loci was analyzed by unconditional Logistic regression analysis.A difference in hemisphere commensalism.Results The morbidity of PSD was 41.3%(52/126),with 21.4%(27/126),12.7%(16/126),7.1%(9/126)in mild,moderate and severe PSD respectively.The frontal lobe(OR=2.824,95%CI=1.189-6.706)and the temporal lobe(OR=3.579,95%CI=1.233-10.393)cerebral infarction were correlated with the occurrence of PSD.The long-term PSD severity was more in frontal lobe than in temporal lobe(χ2=6.399,P<0.05).The average volume of cerebral infarction was larger in PSD group than in non-PSD group(t=3.271,P<0.05),and the average number of cerebral infarction loci was more in PSD group than in non-PSD group(t=3.176,P<0.05).The more severe the degree of depression according to HAMD17,the larger the average volume of cerebral infarction(F=6.280,P<0.05)and the more the average number of lesions(F=6.132,P<0.05).Conclusions The development of long-term PSD in the first-episode elderly patients is affected by the invasion site.The frontal lobe and temporal lobe infarction are independent risk factors for long-term PSD in patients with ischemic stroke,and the PSD was more severe in frontal lobe infarction than in temporal lobe infarction.

Objective To investigate the activity concentration of 90St in tea produced in Chinese typical regions,enrich the baseline data for 90Sr level in Chinese tea,and evaluate possible exposure doses to people.Methods Samples were carbonized,ashed,digested and leached,and then extraction chromatography method was used to separate 90Sr and 90y.After preparation of sample source,radioactivity of 90Y was measured using low-level α/β counter.Results Twenty six kinds of tea produced in 16 typical regions from 26 cities of 16 provinces were collected in 2016,and their 90Sr activity concentrations were analyzed using the separation method of di (2-ethylhexyl) phosphate (HDEHP) extraction chromatography.The results revealed that the activity concentrations in 26 kinds of tea samples ranged from 0.28 to 3.78 Bq/kg,and contributed possible exposure doses of 0.44 × 10-2-6.00 × 10-2 μSv to each people.Conclusions These doses were far less than the ICRP annual dose limit of 1 mSv for the public,suggesting less impact on people's health.

Objective To investigate the correlation between retinal deformation degree and retina thickness (RT) detected by optic coherent tomography (OTC) in patients with idiopathic macular epiretinal membrane (IMEM). Methods The 66 eyes (56 patients) with IMEM diagnosed by OCT were retrospectively analyzed in this study. After best corrected visual acuity (BCVA), ocular fundus and OCT examination, patients were divided into three groups (mild, medium and severe) according to retinal deformation degrees. The RT value was measured manually. Results There were significant differences in RT values between mild, moderate and severe groups:(311.95 ±51.78) μm, (447.13±41.95) μm and (560.00± 58.23) μm (P<0.05). The values of BCVA were 0.78±0.16, 0.38±0.12 and 0.27±0.14 for mild, moderate and severe groups, there were significant differences between them (P<0.05). There was no significant correlation between RT and BCVA in mild group (r=-0.352,P=0.128). There was negative correlation between RT and BCVA in medium group and serious group (r=-0.768 and-0.482,P<0.05). Conclusion The retinal deformation degree and RT are two objective indicators to assess visual performance in patients of IMEM. When RT is more than 400 μm, it can be used as objective criteria for surgical intervention.
