Objective To observe the diffusion and aggregation of the microtubule associated protein tau(MAPT)modu?lated by phosphatase and tensin homolog deleted on chromosome ten(PTEN)during the nerve cell differentiation by human bone marrow stem cells(BMSC)in vitro, and to analyse the signification. Methods Adult bone marrow stem cells were iso?lated and induced into nerve-like cells by some cytokines in vitro. The mRNA expression of MAPT was detected by semi-quantitative RT-PCR and Western blot assay. The patterns of diffusion and aggregation of the MAPT association of the actin were indicated by Phalloidin-fluoresceineisothioeyanate (FITC) and immunofluorescence (IF) cyto-chemistry, and observed by the laser-confocal microscopy. Results The MAPT mRNA levels were 0.24 ± 0.04 and 0.52 ± 0.04 at 1 week and 2 weeks after the induction,which were significantly higher compared with those of BMSC (0.04 ± 0.02) after the induction (P<0.05). The MAPT protein levels were 0.18 ± 0.03 and 0.44 ± 0.05 at 1 week and 2 weeks after the induction, which were significantly higher compared those of BMSC (0.06 ± 0.04, P<0.05). The distribution patterns of MAPT were changed from the diffusion to the aggregation in cells after treatment by BPV. The nerve-like cells appeared the characteristic of po?larization. Conclusion When the nerve cells derived from bone marrow stem cells obtain the mature differentiation, PTEN may possess the ability of modulating the diffusion and aggregation of MAPT in vitro, also may provide a kind of material ba?sis for the growth of the nerve axon.

Objective To investigate the effect of hyperbaric oxygen( HBO) in craniotomy for traumatic brain injury. Methods The 90 patients with traumatic brain injury who received craniotomy in our hospital from March 2012 to September 2014 were divided into the obser-vation group(51 cases) which received HBO therapy additionally and the control group(39 cases). The remission rate of brain edema,GCS score,incidence of lung infection,infarction incidence and subdural effusion incidence at the same course of HBO treatment between the two groups were observed and compared. Rsults The remission rate of cerebral edema of observation group was higher than that of control group after a course of HBO treatment. And 6 days,9 days,12 days and 15 days after the course of HBO treatment,the GCS scores of observation group/control group were 8. 2/7. 8,9. 8/9. 0,11. 2/10. 3 and 12. 2/12. 0,respectively. The lung infection incidence of study group was lower than that of control group. Conclusion HBO treatment can improve the remission rate of brain edema and GCS scores, and it can reduce lung infection incidence in craniotomy for traumatic brain injury.

Objective To evaluate the association between R353Q polymorphism of the coagulation factor Ⅶ gene and cerebral infarction in Chinese Han people. Methods Restriction fragment length polymorphism(PCR-RFLP) methods was adopted to detect FⅦR353Q genotype and R、Q allelomorphie gone frequency of 100 cerebral infarction(CI) patients and 106 healthy people. Results There was FⅦR353Q polymorphism in the CI patients and healthy subjects. RR and RQ genotype could be found in the control group and CI group. RR and RQ genotype dis-position consistented with Hardy-weinberg equilibrium. In CI group,RR genotype was in 91 cases,RQ was in 9 cases and QQ in 0 case(the distribution frequencies were 91.00% ,9.00% and 0), and in the healthy subjects, those are 94 cases, 12 cases and 0 case(88.70% ,11.30% and 0). In the control group and CI group,R allele genotype fre-quencies were 94.33% and 95.50%, and Q were 5.67% and 4.50%. There was not significantly different in the R353Q polymorphism (χ20.3027, P=0.5822);Q allele genotype was not significantly different between the cases of control group and CI patients(χ20.2865, P=0.5925). Conclusion There are the FⅦR353Q polymorphism in Han population,however,the idea that the Q allele is a protective factor in CI is not supported.

Objective To investigate the effects of Kangpa bolus on behaviors, dopamine and its metabolites of striatum in animals with Parkinson' s disease (PD). Methods The mice models of muscle tremor and rigor were established to observe the antagonism of Kangpa bolus. Step-down and step-through tests were used to evaluate the effects of Kangpa bolus on learning and memory function in mice. The rat model of PD was established to observe the effects of Kangpa bolus on rotation behaviors. The contents of DA and homovanillic acid( HVA) in the injured side of striatum were detected by ELISA. Results Compared with model group(723. 1 ±79.3) s,the duration of tremor in mice shortened significantly (P < 0. 01) in Kangpa bolus high dose and middle dose group ((548.0±27.0)s,(590.9 ±28.7)s). Compared with model group(3194.5 ±251.7)s,the duration of rigor in mice shortened significantly(P<0.01) in Kangpa bolus all dose group((2300.1 ±352.5)s,(2478.2 ±276.6)s, (2559.3 ±207.6) s). In step-down test, compared with model group (3. 10 ±0.74), the number of errors decreased significantly(P<0.01) in Kangpa bolus high dose and middle dose group (1.60 ±0. 97,1. 80 ±0.63). In step-through test, compared with model group( 2.30 ± 0. 68), the number of errors decreased significantly (P < 0.01) in Kangpa bolus high dose and middle dose group(0.80 ±0.79,1.10 ±0.74). Compared with model group (340.6 ±18.8) , the number of rotations of PD rats in thirty minutes reduced significantly (P< 0.01) in Kangpa bolus high dose and middle dose group(286.5 ± 12.1,296.6 ± 12.7) after three weeks treatment. Compared with model group(9.43 ±1.79,0. 87 ±0.12) nmol/L,the contents of DA and HVA in the injured side of striatum increased significantly(P<0. 01 ) in Kangpa bolus high dose( 18. 9 ±4. 01,1. 50 ± 1. 39) nmol/L and middle dose group (17.3±3.01,1.39±0.53)nmol/L Conclusion Kangpa bolus has some therapeutic effects on the animals of PD.

OBJECTIVETo investigate the characteristic changes in the infrared thermogram of chronic prostatitis (CP) patients and find some evidence for the auxiliary diagnosis and therapeutic evaluation of the disease.
METHODSFifty CP patients and 20 healthy male volunteers were included in this clinical trial. The infrared thermograms of the subjects were compared between the two groups for characteristic changes. The values obtained were used for the auxiliary diagnosis and therapeutic evaluation of the disease.
RESULTSCompared with the healthy males in the same age group, the CP patients showed extremely significant abnormal changes in the average temperature value in the hypogastrium (H), pubis (P), scrotum (S), and groin (G) (P < 0.01). The average H temperature value of the CP patients was correlated negatively with the CP symptom index (CPSI) (P < 0.01, Pearsons correlation coefficient = -0.519), while the S temperature positively with CPSI (P < 0.01, Pearsons correlation coefficient = 0.446). In addition to the H value, the P, S, and G values were all correlated in different degrees with CPSI (P < 0.01), which the S value exhibited the most significantly negative correlation (Pearson's correlation coefficient = -0.898).
CONCLUSIONThere are some characteristic changes in the hypogastrium temperature of CP patients in the infrared thermogram, which has a potential application value for the auxiliary diagnosis, symptom assessment, and therapeutic evaluation of CP.

AIM: To study the change of intercellular adhesion molecule-1(ICAM-1) expression in intestine tissues of mice induced by LPS and regulatory effect of p38 mitogen-activated protein kinase (p38 MAPK) on ICAM-1 expression. METHODS: Protein and mRNA of ICAM-1 were measured using Western blotting and RT-PCR respectively in intestine tissue of BALB/c mice treated by lipopolysaccharide(LPS) or LPS plus SB203580, a specific inhibitor of p38 MAPK. RESULTS: Compared with control group, the expression of ICAM-1 protein and mRNA was increased significantly by LPS stimulation in dose- and time-dependent manner. ICAM-1 expression reached peak value at 12-36 h after LPS stimulation. 20.0 mg/kg of LPS could induce the maximum of ICAM-1 expression. Pretreatment of mice with SB203580 for 30 min could inhibit significantly LPS-induced expression of ICAM-1 protein and mRNA expression in mouse intestine tissues. CONCLUSIONS: These data highlight that LPS could up-regulate ICAM-1 protein and mRNA expression in intestine tissue of mice in dose- and time-dependent manner, and p38 MAPK signal pathway plays an important role in ICAM-1 expression induced by LPS. It suggests that inhibition of p38 MAPK might be a useful principle for the prevention and treatment of intestine damage of endotoxic shock.
