Objective To investigate the relationship between p53,COX-2,Bax,c-myc genes and colorectal carcinoma complicated with chronic schistosomiasis. Methods One hundred and sixty patients with colorectal carcinoma were selected and divided into two groups;a schistosomiasis group(colorectal carcinoma complicated with chronic schistosomiasis,n=80)and a non-schistosomiasis group(colorectal carcinoma uncomplicated with chronic schistosomiasis,n=80). The tissue microarray tech-niques and immunohistochemistry method were used in all the patients to detect the expressions of p53,COX-2,Bax and c-myc proteins. Results The positive rate and level of p53 protein expression in the schistosomiasis group were lower than those in the non-schistosomiasis group,but there were no significant differences between the two groups(both P>0.05). The COX-2 protein in both groups was positive,but the positive expression level of COX-2 in the schistosomiasis group was higher than that in the non-schistosomiasis group,and there was a significant difference between the two groups(P<0.01). The positive rate and level of Bax protein expression were not significantly different between the two groups(both P>0.05). The positive rate of c-myc expression in the schistosomiasis group was higher than that in the non-schistosomiasis group,with a significant difference(P<0.01),but the positive expression level was lower than that in the non-schistosomiasis group,and there was a significant difference between the two groups(P<0.01). Conclusions Schistosome infection may impact on the deficiency of p53 of human colorectal cancer cells. It may promote the excessive expression of COX-2 protein,which is an indirect carcinogenic factor. The expression of Bax gene has no correlation with schistosome infection. The schistosome chronic infection may cause a persistent low level expression of c-myc gene.

Objective To investigate the level of finger systolic blood pressure (FSBP) in healthy young adults. Methods A total of 28 healthy young adults were selected as the study subjects by convenient sampling method. The FSBP of the study subjects was detected at 30 and 10 ℃, and the FSBP index (F_i) was calculated. Results The FSBP of the study subjects at 30 and 10 ℃ were (102.0±16.5) and (104.4±15.2) mmHg, respectively. The FSBP in male group at 30 and 10 ℃ was (99.6±18.6) and (107.2±17.0) mmHg, respectively. The FSBP in female group at 30 and 10 ℃ was (104.4±13.9) and (101.5±2.8) mmHg, respectively. The results of factorial analysis showed that the interaction between gender and temperature on FSBP was statistically significant (P<0.05). FSBP in male group was higher at 10 than 30 ℃ (P<0.05) and higher than female group at 10 ℃ (P<0.05). There was no statistical significance for the main effect of gender, temperature, finger, or the interaction effect of gender and finger, temperature and finger for FSBP (all P>0.05). The average F_i of the study subjects was (98.0±16.6)%, with males and females having the average F_i of (100.7±20.7) % and (95.2±10.6) % respectively. The results of factorial analysis of variance showed that there was no significant difference on F_i in the main effect gender and fingers or the interaction effect between them(all P>0.05). Conclusion The FSBP test could be used as a detection method for assessing peripheral microcirculation function in Chinese population. However, further research is needed to establish reference ranges and influencing factors.

OBJECTIVETo observe the clinical efficacy differences between modified lateral position and prone position in patients treated with electroacupuncture (EA) for lumbar herniated disc (LHD).

METHODSSeventy-six patients with LHD were randomly divided into a lateral position group and a prone position group, 38 cases in each one. The acupoint selection and treatment method were identical in the two groups except the position. Mingmen (GV 4), Yaoyangguan (GV 3), Dachangshu (BL 25), Xiaochangshu (BL 27), Zhibian (BL 54) and Huantiao (GB 30) were selected. EA was given three times a week, ten times were taken as one course and totally 20 times were given. The visual analogue scale (VAS) and Japanese orthopaedic association (JOA) scale were taken as efficacy criteria, which were evaluated before and after treatment as well as one month after treatment.

RESULTSAfter treatment, VAS and JOA were significantly improved in the two groups (lateral position group:JOA 10.60±2.60 vs 18.92±3.87, VAS 8.13±0.99 vs 2.34±0.81; prone position group:JOA 10.94±2.06 vs 17.02±3.96, VAS 8.02±1.05 vs 2.86±0.96, all<0.01); the VAS and JOA in the lateral position group were higher than those in the prone position group (both<0.05). One month after treatment, VAS and JOA were significantly improved in the two groups (all<0.01), which was more significant in the lateral position group (both<0.05).

CONCLUSIONSThe treatment position could influence the efficacy of EA for LHD, and lateral position pre-sents certain advantages to prone position group.
