OBJECTIVE: To explore the influence of hyperbaric oxygen (HBO) treatment on neural plasticity and it's mechanism in experimental rats with cerebral ischemia. METHODS: Ninety-healthy male adult Sprague-Dawley rats (3 to approximately 4 month old) were randomly divided into a pseudo-operative group, a model group, and an HBO therapy group. The middle cerebral artery occlusion model was duplicated with suture methods, then we used beam walking test (BWT) to determine the motor skill of the rats and immunohistochemistry method to detect the distribution and location of microtubule-associated protein-2 (MAP-2) and glial fibrillary acidic protein (GFAP). Quantitative real-time PCR was used to detect the expression of Map-2 mRNA and GFAP mRNA. RESULTS: Immunohistochemistry showed that the fluorescence gray scale value of Map-2 in the HBO group was the highest in 3 groups at 1st week and 2nd week (P<0.05).The value of GFAP was lower than that of the model group but higher than that of the sham operated group (P<0.05). Real-time fluorescence-quantitative PCR indicated that the Map-2 mRNA of HBO group was the highest in 3 groups at 1st week and 2nd week (P<0.05); but the value of GFAP mRNA in the HBO group is lower than that of the model group,but higher than that of the sham operated group at 1st week and 2nd week (P<0.05). CONCLUSION After cerebral infarction, giving hyperbaric oxygenation treatment can improve the limbs motor function, and hyperbaric oxygenation treatment can increase the expression of Map-2 and decrease the expression of GFAP, which promote neural plasticity.

OBJECTIVETo investigate the molecular mechanism of platycodin D showing the inhibitory effect on proliferation and induced apoptosis of humane long cancer cells A549.

METHODHumane long cancer cells A549 were cultured in vitro, with the final PD concentration of 5-20 micromol x L(-1). PD's inhibitory effect on cell proliferation was examined by MTT assay. Morphological changes in cells were observed with microscope. The cell apoptosis rate was detected by Annexin V-FITC/PI double staining. The change of mitochondrial membrane potential was detected by JC-1. The protein expressing of leaved Caspase-3, cleaved Caspase-9, cleaved PARP, Bcl-2, Bcl-xl, Bak and Bax were detected by Western blot analysis.

RESULTPD could inhibit the proliferation of A549 cells and show stronger effect with the increase of concentration and over time. Compared with the control group, PDs of different concentration showed significant increase in the cell apoptosis rate, decrease in mitochondrial membrane potential after 24 h. Protein electrophoresis inspection showed cut segments in both protein Caspase-3 and Caspase-9 and notable fractures with time. Further study found that PD decreased Bcl-2, Bcl-xl proteins and increased Bax, Bak proteins after processing A549 cells.

CONCLUSIONPD shows notable effect on cytotoxicity and can induce A549 cell apoptosis. It causes decrease in mitochondrial membrane potential by regulating Bax, Bak, Bcl-2 and Bcl-xl expressions, and thus activating caspase and finally causing long cancer cell apoptosis.

Objective To evaluate the effect of serum chromium on oral cancer after adjusting the covarite between groups based on propensity score matching (PSM). Methods We performed a case-control study in 395 cases of newly diagnosed primary oral cancer from the First Affiliated Hospital of Fujian Medical University and 1 240 controls from the same community from January 2010 to February 2018. Using the PSM to select 309 controls randomly which were matched with the cases by 1 ∶1 matching. Conditional Logistic regression model was used to explore the association between chromium and oral cancer. Results The level of serum chromium was 178.91 (121.83-284.19) μg/L in the case group, which was lower than 324.27 (264.82-397.69) μg/L in control group, the difference was statistically significant (P＜0.001). Dose-response analysis showed that the risk of oral cancer gradually decreased with the increase of serum chromium, which presented a negative correlation. There was a negative correlation between serum chromium level and the risk for oral cancer by conditional Logistic regression,the aOR of serum chromium in the Q2, Q3 and Q4 compared with the Q1 were 0.14 (0.08-0.26), 0.15 (0.08-0.28) and 0.10 (0.05-0.20),with significant trend (Ptrend＜0.001). Stratified analysis showed the negative correlation between serum chromium and oral cancer by smoking, drinking tea, not drinking alcohol status and fish, fruits and green vegetables intake frequencies. Conclusions The high level of serum chromium is a protective factor for the incidence of oral cancer, and the higher of serum chromium, the lower risk of developing oral cancer.

OBJECTIVETo explore the association between single nucleotide polymorphisms (SNPs) of KLK1 gene and cerebral hemorrhage in Changsha Han Chinese.

METHODSTwo hundred and seventy-three cerebral hemorrhage (CH) patients and 140 healthy controls were collected. The SNPs of rs5516 and rs5517 loci of KLK1 gene were analyzed by SNaPshot methods and direct sequencing.

RESULTS(1)Genotype and allele frequencies in rs5516 locus had no difference between the CH patients and controls (P> 0.05). However, the A allele frequency of the rs5517 locus in CH patients was higher than that in the control group (0.419, 0.321 respectively, P< 0.05). (2)In the control group,the levels of diastolic blood pressure (DBP) of the GA and AA genotype carriers of the rs5517 locus were significantly higher than those of the GG genotype (P< 0.05), while the levels of blood pressure were not significantly different among different genotypes of the rs5516 polymorphism in both CH patients and the control group(P> 0.05).

CONCLUSIONAuthor's preliminary results suggested that the rs5517 polymorphism was associated with cerebral hemorrhage, while the rs5516 polymorphism was not in Changsha Han Chinese.

The present study was aimed to evaluate the MDR reversal activity of bromotetrandrine (BrTet) in vitro and in vivo. The inhibitory effects of adriamycin (ADM) used alone or in combination with BrTet or Tet on the proliferation of K562 and K562/A02 cells were evaluated by MTT assay. The ADM accumulation and the protein levels of P-glycoprotein (P-gp) were detected by flow cytometry. The mRNA levels of P-gp were determined by RT-PCR. The in vivo effect of BrTet and Tet was investigated by using nude mice grafted with sensitive human leukemia cell line K562 and MDR cell line K562/A02. The results showed that BrTet at 0.25, 0.5 and 1 micromol/L reversed the resistance to ADM in MDR K562/A02 cells in a dose-dependent manner. Flow cytometry suggested that BrTet significantly increased the intracellular accumulation of ADM in K562/A02 cells in a dose-dependent manner. BrTet also inhibited the overexpression of P-gp in K562/A02 cells, and down-regulated mdr1 expression. In nude mice bearing K562 xenografts on the left flank and K562/A02 xenografts on the right flank, intraperitoneal injection of 10 mg/kg BrTet significantly enhanced the antitumor activity of ADM against K562/A02 xenografts with inhibitory rates of 26.1%, while ADM alone inhibited the growth of K562/A02 xenografts only by 5.8%. No enhancement effect by BrTet was seen in K562 xenografts. It is concluded that BrTet shows significant MDR reversal activity in vitro and in vivo. Its activity may be related to the inhibition of P-gp overexpression and the increase intracellular accumulation of anticancer drugs. BrTet may be a promising-MDR modulator for eventual assessment in the clinic.
