Thiopurine S-methyltransferase (TPMT) is an important and key cytoplasmic enzyme in the metabolism of thiopurine drugs,whose activity can directly determine the amount of thiopurine drugs metabolized to cytotoxic 6-thioguanine nucleotides and consequently influence clinical efficacy and adverse drug reactions of thiopurine drugs.In order to deepen knowledge and role of genetic polymorphism of tpmt in the individualized thiopurine drug treatment,this present review mainly covered the following three frequently concerned aspects,including i) whether or not to determine the activity of TPMT priot to treatment of thiopurine drugs;ii) to genotype or to phenotype;iii) how to choose genotype methods.

Objective To investigate the cognition and behaviors of sun-protection and the facial photoaging in a Nanjing population, and to analyze the relationships between them. Methods The objects being investigated in Nanjing (n=974) were divided into 10 groups according to age. The ordinary information, knowledge and behavior of sun-protection and Glogau photoageing type of face were studied by questionnaires. The results were analyzed by a logistic regression model to select the related factors to photoageing. Results The risk of skin photoageing increased with age. Most of the 46-65 years old crowds were type Ⅲ photoageing. Most of the objects being investigated had some knowledge and active awareness of sun-protection and could use some ways to protect themselves from sun. However, most people did not use the sunscreen correctly. Those who had higher level awareness and knowledge of sunprotection suffered less risk from skin photoageing. Sunbath without sunscreen for a long time outside activity was a high risk factor of development to skin photoageing. Shade, broad-brimmed hat and sun-protection in autumn were the protective factors. Conclusion Active awareness and correct methods could help prevent skin photoageing. In order to avoid the damages to skin from ultraviolet efficiently, the accurate ways of using sunscreens should be well understood.

Objective: To optimize the ultrahigh pressure extraction ( UPE) process for forsythoside from Forsythia suspensa by Box-Behnken experimental design. Methods:On the basis of single factor screening, a three-factor and three-level Box-Behnken ex-perimental design was employed with liquid/material ratio( X1 ) , extraction pressure ( X2 ) and extraction time ( X3 ) as the independent variables. The response variable was the extraction yield of forsythoside. Results:The optimal UPE conditions for forsythoside were as follows:the ratio of solvent to material (ml·g-1) was 70, the extraction pressure was 151 MPa, and the extraction time was 114 s. With the optimal extraction process, the extraction yield of forsythoside was 13. 15 mg·g-1 . Conclusion:As a novel extraction tech-nology for Chinese herbal medicines, UPE procedure has higher extraction yield, lower extraction temperature, shorter extraction time and less power consumption, which provides a brand-new method for the extraction of forsythoside from Forsythia suspensa.

Objective To evaluate the value and clinical application of cardiac structure Z scores in children with preoperative tetralogy of Fallot (TOF) by echocardiography. Methods Considering the result of 31 patients who underwent echocardiography in Shenzhen Children’s Hospital before TOF repair from January 2011 to September 2013, the median age was 10 months (range:3 days to 14 years). Other 31 normal children were selected as normal control group with age-and sex-matched, the median age was 10 months (range: 6 days to 13 years). Echocardiographic measurements included the diameter of right ventricular outflow tract (RVOT), pulmonary valve diameter (PVD), left pulmonary artery diameter (LPAD), right pulmonary artery diameter (RPAD), pulmonary valve peak velocity (PV-Vmax), tricuspid annulus diameter (TVD), mitral annulus diameter (MAD), left ventricular end-diastolic volume (LVEDV) and left ventricular mass (LVmass). Shenzhen Children’s Hospital pediatric echocardiography normal reference values and the regression equation are applied to obtain the forecast average, and using the Z-score formula into the standard value (Z=[M-y]/ MSE ). Results There was no significant difference in body surface area between the TOF group and control group (P>0.05). Compared with control group, the true value of RVOT reduced significantly in TOF group, its Z-score showed negative values increase (-4.87±1.86 vs 0.33±0.93, t=-13.90, P<0.05). PVD, LPAD and RPAD reduced significantly in TOF group, those Z scores showed a negative value increase (-4.15±2.93 vs 0.11±0.85, t=-7.76;-1.35±2.38 vs 0.66±1.17, t=-4.24;-1.47±2.03 vs 0.59±1.04, t=-4.94;all P<0.05). While PV-Vmax increased significantly, and it’s Z score showed a positive value increase (8.38±0.19 vs 0.24±0.98, t=29.50, P<0.05). TVD of TOF patients was slightly larger than the control group (P=0.10), but the Z score was significant greater than the control group (1.00±1.17 vs 0.29±0.52, t=3.06, P<0.05). MV-D, LVEDV and LVmass of TOF patients were slightly decreased than the control group (all P>0.05), but the Z scores of TOF were significantly reduced than the control group (0.25±0.78 vs 0.76±0.65, t=-2.75;-0.92±1.94 vs 0.03±1.01, t=-2.41;-0.83±1.59 vs 0.67±0.69, t=-4.71; all P<0.05). The Z scores of RVOT, PVD, LPAD and RPAD had no significant difference between transannular patch surgery and pulmonary valve-sparing repair patients (-4.89±2.03 vs -4.84±1.67, t=-0.08; -4.73±3.49 vs -3.34±1.75, t=-1.31; -1.88±2.54 vs -0.62±2.00, t=-1.49;-1.89±1.90 vs-0.84±2.15, t=-1.41;all P>0.05). For the Z scores of PV-Vmax, there were no significant difference between transannular patch surgery and pulmonary valve-sparing repair (8.58±1.20 vs 8.12±1.16, t=1.07, P>0.05). Conclusions The Z scores value of cardiac structure can be used in quantitative analysis of RVOT obstruction and development of left ventricular backward of TOF. The Z score of transannular patch surgery is more lower than pulmonary valve-sparing repair patients. The normalized Z score by body surface area correction is important for the preoperative diagnosis and the surgical planning.
