2.Research involved with 5-Fu metabolize and resistance mechanism
Cancer Research and Clinic 2009;21(1):67-69
5-fluorouracil (5-Fu) as an antimetabolite drug,has been widely used in the treatment of various solid tumors.However, due to the heterogeneity of tumor and the impact of the individual, some patients still have drug resistance or serious lethal toxicity reaction.The text focuses on the research progress of pharmacogenomics and pharmacogenetics of some forecast elements which affect the efficacy and toxicity of 5-Fu,and discussed their guiding role on the choice of chemotherapy drugs.
3.Analysis of central corneal thickness in different degrees of diabetic retinopathy
International Eye Science 2014;(6):1061-1063
AIM: To study central corneal thickness ( CCT ) and correlation in different degrees of diabetic retinopathy ( DR) .
METHODS:A total of 65 cases (130 eyes) with different degrees of DR and 35 normal cases (70 eyes) as the age-and gender-matched control group were examined by corneal endothelial microscope, to measure CCT and statistics
RESULTS: Compared to control group, there were no significant difference of CCT both mild and medium nonproliferative diabetic retinopathy ( NPDR) groups ( P>0. 05 ). While the CCT of severe NPDR group and proliferative diabetic retinopathy ( PDR ) group were thicker than control group, and the differences were statistically significant (P<0. 05); Pairwise comparison in different degrees of DR groups: the CCT of severe NPDR and mild NPDR groups were thicker than PDR group, and the differences were statistically significant ( P<0. 05 );compared to medium NPDR, the CCT of PDR was thicker (P<0. 05);The thickness of CCT increases with severity of DR, there was positive linear correlation ( r=0. 173, P<0-05).
CONCLUSION: The CCT increases with severity of DR. Taking care of protecting corneal endothelium is very important in the time of therapeutic measure, especially intraocular operation, to decrease complication.

Journal of Shanghai Jiaotong University(Medical Science) 2006;0(02):-
Objective To observe the hemodynamic effects of open-loop target controlled infusion (OLTCI) and closed-loop target controlled infusion (CLTCI) of propofol and fentanyl for general anesthesia induction. Methods Twenty-four female patients with ASA grade I-II who were performed thyroidectomy were randomly allocated into two groups: OLTCI group and CLTCI group(n=12). In OLTCI group, anesthesia induction and maintenance were performed with propofol and fentanyl at the target concentrations of 3 ?g/mL and 3 ng/mL, respectively. In CLTCI group, double CLTCI were performed. Titrations of propofol and fentanyl were guided with bispectral index (BIS) and product of systolic pressure and heart rate (HR). Initiative concentrations of this closed-loop system were 3 ?g/mL and 3 ng/mL, step-up or step-down concentrations were 0.5 ?g/mL and 0.5 ng/mL, and the highest concentrations were 6 ?g/mL and 5 ng/mL, respectively. HR, mean arterial pressure (MAP), HR variability, BIS value and the dosages of propofol and fentanyl in various time of the two groups were recorded. Results One min after intubation and simulative incision stimulation, BIS value of both groups were increased, but the BIS value in CLTCI group was less increased than OLTCI group(P

Objective:To develop an HPLC-DAD method for the simultaneous determination of seven alkaloid constitutents, so-phoranholN-oxide, oxymatrine, sophoridine, oxysophocarpine, sophoranol, matrine and sophocarpine in Sophora flavescens Ait. Meth-ods:The chromatographic separation was performed on an Agilent Zorbax C18 column (150 mm × 4. 6 mm, 5μm) with 10 mmol·L-1 NH4Ac(0.1% ammonia, pH=9.0)(A)-acetonitrile-methanol(1 ∶22) containing 20 mmol·L-1NH4Ac(B) as the mobile phase with gradient elution at the flow rate of 1 ml·min-1 . The detection wavelength was set at 220 nm,and the column temperature was maintained at 30 ℃. Results: SophoranholN-oxide, oxymatrine, sophoridine, oxysoph-ocarpine, sophoranol, matrine and sopho-carpine was linear within the range of 0.093-1.860 μg(r =0.999 6) , 0.530-10.600 μg (r =0.999 7), 0.062-1.240 μg (r =0. 999 8), 0. 281-5. 620 μg (r=0. 999 9), 0. 026-0. 520 μg (r=0. 999 8) ,0. 036-0. 720 μg (r=0. 999 7) and 0. 032-0. 640 μg (r=0. 999 6), respectively. The average recovery was 97. 5%, 98. 2%, 99. 0%, 99. 4%, 99. 2%, 98. 2% and 98. 7%, and RSD was 1. 18%, 0. 92%, 1. 43%, 1. 04%, 0. 81%, 0. 43% and 0. 88%(n =6), respectively. Conclusion:The method is convenient, accurate and reproducible in the quality control of multicomponents in Sophora flavescens Ait.

Objective:To investigate the expression of metabolic enzymes of fluoropyrimidines in primary colorectal cancer. Methods: Sixty-one cases of pathological confirmed primary colorectal cancer were collected in Beijing Cancer Hospital from August 2003 to February 2004. The expressions of thymidylate synthase (TS), dihydropyrimidine dehydrogenase (DPD) and orotate phosphoribosyl transferase (OPRT) were detected in paired tumor tissues and non-cancerous tissues by RT-PCR. Results: Expression of each enzyme in tumor tissues was positively correlated with that in paired non-cancerous tissues respectively. Compared with the expression of each enzyme in cancer with that in non-cancer, OPRT was higher in cancer while that of DPD and TS was comparable. The expression of OPRT was approximately 4.38-folds higher in colorectal cancer tissues than that in non-cancerous tissues (P0.000). The lowest expression of OPRT was found in mucinous carcinoma while the highest levels in poorly-differentiated adenocarcinoma. There were correlations between the ratio of tumor tissues / non-cancerous tissues OPRT expression (T/N) and metastasis to the lymph nodes (r0.36; P0.005), small vessel invasion (r0.26; P0.041) and differentiation (r-0.33; P0.009). Conclusion: The detection of three enzymes by means of RT-PCR is practical and can be used in clinical application. Our results also suggest that OPRT is a potential biomarker in predicating prognosis of colorectal cancer.

Objective To investigate the effect of cognitive intervention on language function and quality of life (QOL) in elderly patients with post-stroke aphasia.Methods Fifty-five elderly patients with post-stroke aphasia were randomly divided into the control group (n =27) and the experimental group (n=28).The control group received comprehensive treatment including speech-language therapy (SLT),while the experimental group was subjected to additional cognitive intervention.All patients were enrolled in an eight-week rehabilitation program.The mini-mental state examination (MMSE) was used to assess cognitive function,a device for diagnosis and treatment of language disorders,ZM 2.1,was used to evaluate language function,and the 36-item short-form health survey (SF-36) (Chinese version) was used to assess quality of life (QOL),before and after treatment.Results After treatment,MMSE scores,language function scores in all categories and QOL scores in all dimensions improved in both groups (P<0.05 for both).Furthermore,after treatment,there were significant differences between the two groups in MMSE scores of orientation,recall,attention and calculation,and in scores of overall language ability and the individual categories (P<0.05 for all).Scores of the experimental group vs.the control group for the individual categories of language function were as follows:simple instructions (76.6 ± 14.1 vs.67.4± 19.3),complex instructions (66.1±12.8 vs.58.2±14.9),yes or no (72.5±12.1 vs.63.0±14.1),naming (55.0 19.5 vs.43.3±22.2),simple comprehension (67.5±21.4 vs.55.620.6),complex comprehension (44.8±17.0 vs.35.0±18.9),listening and reading words (65.4±16.7 vs.53.7±19.3),calculation (39.3±25.8 vs.25.9±19.2),memory (36.4±18.7 vs.26.3±17.8),matching (75.9±18.6 vs.65.3±17.1),simple general knowledge (68.3±18.2 vs.58.0±19.5),complex general knowledge (58.7±17.4 vs.50.0±13.3),orientation (70.7±19.6 vs.60.5±17.2) and comparison (59.9± 14.6 vs.50.2±17.5) (P<0.05 for all).There were significant differences between the two groups in emotional function (66.7±18.2 vs.53.1±21.2),general health (67.2±12.6 vs.60.7±9.8),mental health (71.0±5.6 vs.63.1±4.2),social functioning (64.7±9.0 vs.59.3±10.2) and vitality (55.4±14.8 vs.46.9±15.6) (P<0.05 for all).Conclusions Cognitive intervention combined with SLT can contribute to the recovery of language function and the improvement of QOL in elderly patients with post-stroke aphasia.
