It has been indicated that the oncogene and anti-oncogene are closely related to the development and progression of cancer.With the development of molecular biology,detection of oncogene and anti-oncogene has become an important approach for clinical warning and diagnosing of cancer.Since the establishment of the molecular model of colon cancer by Fearon and Vogelstein in 1990,the genetics of colorectal cancer has gained major advances in early diagnosis.Early detection of related gene mutations is helpful for the early warning of colorectal cancer,especially for palients with hereditary cancer(the detection rate is fairly high).This review summarizes the progression of study on biomarkers of colorectal cancer.

Objective To introduce the procedure and the clinical experience of two lengthened vascular pedicled flaps in hands to repair soft tissue defect distal to the middle segment of finger. Methods From June 2002 to April 2004, 6 cases with skin and soft tissue defect distal to the middle segment of index and middle finger were treated by the dorsal hand U-I shaped vascular pedicled island flaps, the large area of the repair flap was 5.0 cm?2.8 cm, and the small area was 3.8 cm?2.5 cm, an average of the pedicle length was 8.0 cm. 10 cases with skin and soft tissue defect beyond the middle segment of 2 to 4 finger were treated by the digital artery reversed island flaps of adjacent digit, the large area of the repair flap was 4.6 cm?2.5 cm, and the small area was 2.5 cm?2.4 cm, an average of the pedicle length was 4.0 cm. There were 11 males and 5 females, aged from 18 to 42 years (average, 26 years). Results All flaps survived in 16 cases. After 8 to 24 months postoperative follow-up, with an average of 15 months, the blood supply and texture of the flaps were excellent, their outer aspect and function were satisfactory. Among 4 cases of the dorsal hand U-I shaped vascular pedicled island flaps with connecting nerves, the two-point discrimination was 9 to 11 mm, while in 9 cases of the digital artery reversed island flaps with connecting nerves, the two-point discrimination was 6 to 8 mm. Of the 3 cases that the nerves were disconnected, the sensation of the healed flaps only recovered to S2 or S3. Conclusion The dorsal hand U-I shaped vascular pedicled island flaps and the digital artery reversed island flaps of adjacent digit can form a longer vascular pedicle, to repair the skin and soft tissue defect distal to the middle segment of finger. They are the reliable flaps with good blood supply, and can recover the sensation through connecting nerves.

Objective:To compare the antihypertensive effects of tuina at Taichong (LR 3),Neiguan (PC 6) and Qiaogong (Extra) to screen the best tuina protocol for primary hypertension due to liver-fire flaming-up.Methods:A total of 102 patients with primary hypertension due to liver-fire flaming-up were randomly divided into a Taichong (LR 3) group,a Neiguan (PC 6) group and a Qiaogong (Extra) group according to the random number table,with 34 cases in each group.Patients in the three groups received 4-week tuina treatment with the corresponding acupoint respectively.The blood pressure was recorded by benchtop mercury sphygmomanometer before tuina,immediately after tuina treatment,30 min and 60 min after tuina treatment with the patient in a supine position in a quiet treatment room.The total effective rate was observed.Results:The systolic and diastolic blood pressures of the three groups all decreased after treatment (all P＜0.05).The decrease of systolic and diastolic blood pressure at different time points after treatment in the Qiaogong (Extra) group and the Taichong (LR 3) group were better than those in the Neiguan (PC 6) group (all P＜0.05).Qiaogong (Extra) group had the highest total effective rate though there was no statistical difference in the total effective rate among the three groups (P＞0.05).Conclusion:Treating primary hypertension due to liver-fire flaming-up with tuina at Taichong (LR 3),Neiguan (PC 6) and Qiaogong (Extra) can reduce systolic and diastolic blood pressure respectively,among which Qiaogong (Extra) has the highest total effective rate.

OBJECTIVE　To develop an HPLC method for the determination of floxuridine in human serum.METHODS　With metronidazole as the internal standard,200 μL of serum was extracted by n-propyl alcohol/methyl t-butyl ether in a two-step extraction.The organic layer was evaporated under nitrogen stream and the residual was reconstituted with the mobile plase.A Shim-Pack CLC-ODS column was selected and the mobile phase was consisted of acetonitrile-phosphate buffer-water (75∶100∶900) at a flow rate of 0.6 mL*min-1.The detection wavelength was 268 nm.RESULTS　A linearitywas obtained from 0.005 to 0.5 mg*L-1 of floxuridine in serum with a good correlation coefficient (r=0.9999,n=8).The intra-run and inter-run coefficients of variation were less than 4.09%.The mean recoveries were 103.00%,107.00% and 100.88% for the low,middle and high concentrations of check samples,respectively.The limit of detection was 0.001 mg*L-1.CONCLUSION　The method was sensitive,specific and simple.It is suitable for clinical pharmacokinetic study.

Objective To understand the perceptions of normal and ideal body size in registered nurses and nursing students,and to analyze the impacts of individual weight levels and misperception of body weight on their such cognitions.Methods A cross-sectional survey of 407 nursing students from two hospitals and 466 registered nurses from one hospital was conducted with the questionnaire survey.Sociodemographic information,actual weight,perceived weight levels and scores for figure rating scale were included.Results FRS scores for normal and ideal body size to male were significantly higher than to female either in registered nurses or in nursing students; FRS scores for ideal body size to both sexes were significantly lower than those for normal body size among registered nurses and nursing students.There were no statistically significant associations between FRS scores for normal and ideal body size and individuals' weight levels and misperceptions of body weight among registered nurses and nursing students.Conclusions There existed differences in rating female and male body size among registered nurses and nursing students,with “bigger” normal and ideal body sizes to male,Nurses preferred to “thinner” ideal body size in comparison to normal body size.

Objective To investigate the expressions of endogenous cystathionine-γ-1yase (CSE)/ hydrogen sulfide (H2S) and resolvin E1 (RvE1) in patients with ulcerative colitis (UC),and its effect on the pathogenesis of ulcerative colitis.Methods The distribution and expression of CSE proteins in the rectum mucosa in 60 cases of UC and 30 cases of normal control group were detected by Strept Avidin-Biotin Complex (SABC) immunohistochemistry.The average optical density value of CSE was analyzed with an Image Analyzing systems.The expression of CSE mRNA in the rectum mucosa was detected by real-time polymerase chain reaction (RT-PCR).The levels of H2S and RvE1 in sera were detected by spectrophotometry.Results The expressions of CSE proteins in three groups were detected in the rectum mucosa membrane epithelia.The average optical density value of CSE and the expression of CSE mRNA in patients with active UC were higher than that in normal group and remission of UC.The levels of H2S and RyE1 in patients with active UC were significantly higher than that in normal group and remission of UC.Conclusions The abnormal expressions of CSE/H2S and RyE1 in activity of the UC might play an important role in the pathogenesis of UC.

Objective To study the expression of endogenous cystathionine-β-synthase (CBS) and hydrogen sulfide in patients with ulcerative colitis (UC), and explore their possible role in the pathogenesis of UC. Methods Thirty patients with active period UC (active period UC group), 30 patients with remission period UC (remission period UC group) and 30 healthy controls (control group) were selected, and SABC method was used to observe the localization of CBS in rectal mucosal tissues. The optical density value of CBS was analyzed with image analysis systems. The relative expression of CBS mRNA in the rectal mucosa tissue was detected by reverse transcriptase-polymerase chain reaction (RT-PCR), and the expression of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) was detected as an internal reference. The expression level of mRNA was detected by semi quantitative analysis with gel imaging analysis system, and the results were expressed as the ratio of the target bands to the GAPDH absorbance. The serum level of hydrogen sulfide was detected. Results The serum level of hydrogen sulfide, optical density value of CBS and relative expression of CBS mRNA of rectal mucosal tissues in active period UC group were significantly higher than those in remission period UC group and control group: (90.13 ± 3.12) μmol/L vs. (50.34 ± 2.34) and (48.13 ± 2.75) μmol/L, 0.433 ± 0.037 vs. 0.295 ± 0.064 and 0.214 ± 0.026, 1.532 ± 0.134 vs. 1.031 ± 0.107 and 0.986 ± 0.067, and there were statistical differences (P < 0.01); but there were no statistical differences between remission period UC group and control group (P>0.05). Conclusions The abnomal expression of CBS and hydrogen sulfide in aactive period UC may play an important role in the pathogenesis of UC.

To explore the stability of Shenkang injection respectively in five different solutions to choose the best com-patibility program and improve the rational drug use. Methods:The pH value, insoluble particles and the content of protocatechuic al-dehyde in Shenkang injection were determined after mixed with five solutions. Results:In the 6-hour mixing, the change order of proto-catechuic aldehyde content was 0. 9% sodium chloride injection> 5% fructose injection> 10% invert sugar injection > 5% dextrose injection> 10% glucose injection, especially in 0. 9% sodium chloride injection, the content was decreased by 20%. The number of insoluble particles was increased after the 2-hour mixing except in 10% invert sugar injection solution, and the increase in the four so-lutions was beyond the requirement in the 2010 edition of Chinese Pharmacopoeia, and the number of insoluble particles in 0. 9% sodi-um chloride injection was the highest with the fastest change. During the experimental process, the pH value was stable. Conclusion:The five solutions show influence on stability of Shenkang injection in varying degrees. Shenkang injection in 0. 9% sodium chloride in-jection is the least stable, which should be used with caution in clinics, while invert sugar injection and glucose injection can be the best choice for Shenkang injection and the mixed solution should be used up in 2h.
