Physical performance is an ability with which the sufferers of lumbar disc herniation(LDH) achieve daily work and basic physical activity,including daily activities(such as the diverting movement from standing to sitting),functioning state of nerves and muscles,dailyworking ability and walking gait,etc.;abilities of body performance relative to pains,such as walking ten meters with loads,sit-stand test and Tread mill walk,etc.Most of current rehabilitation evaluation may be influenced by the subjective factors of the examinee or the examiner,but intelligent device for energy expenditure and activity(IDEEA) may be helpful to evaluate physical performance of the LDH patients in a complete,quantity-fixing,systematic and dynamic way.

Objective To investigate the cavernous nerves innervation from prostate apex to glans penis and the relation between cavernous nerves and surrounding tissues and organs. Methods The urethra and penises of three formalin preserved adult cadavers were removed from prostate apex to glans penis.The sections underwent hematoxylin-eosin staining and Bielschowsky nerve staining.The course and distribution of cavernous nerves and relationship between the cavernous nerves and surrounding tissues and organs was observed microscopically and photographed from prostate apex to glans penis. Results From serial sections we found when nerve fibres run along prostate apex,while surrounding the lateral and dorsal aspects of prostate apex and urethra.from 30'clock to 9 0'clock.Most fibres went through smooth muscle and some of them went through the periphery striated muscle and urogenital diaphragm.The distance to urethra lumen was only 3-5 mm.After the nerve fibres went distally and anteriorly,they accompanied closely with cavernous vein plexus and then went into corpora cavernosa.At the distal end of corpora cavernosa,there were"windows"through which the neurovascular bundles communicated between corpora cavernosa and glans penis just like doors to glans penis. Conclusions When nerve fibres run from prostate apex to urogenital diaphragm,along dorsal lateral aspect of prostate and urethra,there are only 3-5 mm to the urethra lumen,so it is very easy to be injured in traumas or operations.In the urethral bulb fragment,the nerves run anteriorly and laterally.out of the periphary muscle,so the cavernous nerves will not be i~ured when dissect urethra bulb from surrounding muscles.Dissect glans penis from distal end of penis in operation would be avoided in order to protect the cavernous nerves between corpora cavernosa and glans penis.

Aim To investigate the activation of prote-ase-activated receptor 2 ( PAR2 ) in regulation of the expression of epidermal growth factor receptor ( EGFR) and apoptosis of lung cancer ( LC) cells. Methods LC cells A549 and its EGFR-silenced counterpart were incubated in the medium added with tryptase. Quanti-tative RT-PCR and Western blotting were used to de-tect the expression of EGFR in A 5 4 9 cells . The apop-tosis and Bax/Bcl-xL of cells were also recorded. Re-sults Treating A549 cells with tryptase in the culture for 48 hrs resulted in a marked increase in the expres-sion of EGFR in A549 cells. Marked decreases in a tryptase dose-dependent manner in apoptotic A549 cells were detected in the presence of tryptase. Expo-sure to tryptase markedly decreased the levels of Bax and increased the levels of Bcl-xL in A549 cells, which were not shown in EGFR-deficient A549 cells. Conclusion Tryptase can increase the expression of EGFR in LC cell line, A549 cells, which protects A549 cells from apoptosis, increases Bcl-xL, and sup-presses Bax in A549 cells.

OBJECTIVE: To establish a HPLC - UV method for determination of hydroxycamptothecin(HCPT) in rabbit tissues (liver, kidney, stomach, lung, spleen, heart, intestine) .METHODS: After homogenization, tissue samples and internal standard, eamptothecine, were precipitated with CH3OH-CH3CN( 1 : 1) and then centrifugalized.20?l of supernatant was injected and measured by HPLC - UV method.The chromatographic column was Lichrospher C18 column: (250mm ? 4.6mm, 5?m), CH3CN - 0.075mol/L NH4AC buffer(pH6.4) (30 : 70, contain 5mol/L tyiethylamine) served as mobile phase with flow rate of 1.0ml/ min .Detection wavelength was 384nm .RESULTS: The retention time of hydroxyeamptothecin was 4.5min.A good linearity was shown in the concentration range of (40- 1 600)ng/ml .The recovery was between 95.24% and 107.58% . The intra day RSD was less than 7.70% and the inter - day RSD was less than 6.69% .CONCLUSION: This method is simple,pratical and accurate.It could be applied to pharmacokinetic study of hydroxyeamptothecin.

Fura—2 was used as a Ca~(2+) indicator to determine the intracellular calcium ion concentra-tion(〔Ca~(2+)〕i)of rat peritoneal macrophages(RPM?s),and APAAP enzyme immnoassay was ap-plied to detect the expression of Ia antigens on RPM?s.The results showed that norepinephrine(NE,10~(-9)mol/L)could markedly increase the〔Ca~(2+)〕i of the RPM?s(p

Objective To investigate the environmental quality and water quality of bathing beach in Haikou,Hainan province and the effects on human health.Methods The investigation of the bathing beach environment and the water quality were conducted according to Bathing Beach Monitoring Regulations(2002).The water samples were collected at PM 3:00-5.00 on May 28th to June 3th in 2007 from three sampling sites,No.1(easily be polluted),No.2(crowded),No.3(less pollution).The questionnaire survey was conducted on the present day and 7 days later,the items included the respiratory,digestive systems infection and eye,ear,nose and skin inflammation,the survey was completed in two days.Results The environment survey of bathing beach suggested that non-point source pollution caused by domestic wastewater emerged on raining days,the salinity was 31‰-33‰,clarity exceeded 30 centimeter and no heat pollution was found.The pH value,chroma,dissolved oxygen,nitrate nitrogen,chemical oxygen demand,inorganic nitrogen,fecal coli group was 8.01-8.10,11.42-15.00 NTU,5.60-6.71 mg/L,0.16- 0.17mg/L,2.70-3.40mg/L,0.19-0.21 mg/L and 35.0-36.0/L respectively.Four hundred and eight questionnaires were eligible, the response rate was over 90%.The results demonstrated that the swimmers were facing to the increased illness risk from the water quality,such as skin pruritus,gastrointestinal allergies,throat sore,eye and ear and nose infections.There was distinct higher proportion in the participants with water contact and complained one or more symptoms than those without water contact(P

Objective To study the prediction value of C-reactive protein (CRP) level to ankylosing spondylitis disease activity score (ASDAS),the most widely used activity score in ankylosing spondylitis (AS).Methods A total of 386 patients with AS were enrolled and divided into 2 groups by CRP≥3.5 mg/L (n =266) and CRP ＜ 3.5 mg/L(n =120).ASDAS-CRP was evaluated in patients with CRP below the normal range (3.5 mg/L) in different subgroups.Three methods were used to test the consistency between ASDAS-CRP and ASDAS-erythrocyte sedimentation rate (ESR).Results The ASDAS-CRP showed a good correlation with the ASDAS-ESR when CRP level was ≥ 3.5 mg/L (r =0.899,P =0.000).In the group of CRP ＜ 3.5 mg/L,ASDAS-ESR showed better consistency with ASDAS-CRP when CRP level was below 1.5 mg/L(intra-class correlation coefficient 0.902;kappa coefficient 0.70).By the evaluation of variant gradient matrix,CRP 1.5 mg/L coincided with disease activity states.Conclusion There is good consistency between ASDAS-CRP and ASDAS-ESR.When CRP level is below the normal range,1.5 mg/L could be a cut-off value to calculate the optimal ASDAS-CRP score.
