Phenylketonuria,an autosomal recessive inherited disease characterized by amino acid metabolism abnormality,has been listed as a screening program for neonatal genetic metabolic diseases in China.Eearly screening and treatment can reduce or even avoid the disease,However,delayed intervention can influence social functioning and psychological development.The research of life quality including psychological and social functioning in phenylketonuria patients has atlracted the increasing attention along with the medical model transformation.In order to study quality of life in patients with phenylketonuria,life quality questionnaires have been developed.It reveals that early and long-term treatments can improve the quality of life.The assessment and present condition as well as the impact factors of quality of life in phenylketonuria patients have been reviewed in this article,which have important value to evaluate the quality of life and guide clinical treatments as well as judge the prognosis of patients with phenylketonuria.

OBJECTIVE: To prevent medication errors during drug subpackage and ensure patients' medication safety. METHODS: Healthcare failure mode and effect analysis (HFMEA) was applied to evaluate the potential failure modes and effects during drug repackaging and dispensing. Thereafter rectification measures was analyzed and carried out in order to prevent the recurrence of failure modes. Risk priority numbers (RPNs) before and after the implication of rectification measures were analyzed using paired t tests. RESULTS: After the application of healthcare failure mode and effect analysis, RPN was statistically significantly (P<0.05) reduced by 60% (P=0.000 2), which affecting the incidences of medication errors during drug unit-dose repackaging. CONCLUSION: The application of healthcare failure mode and effect analysis can effectively prevent medication errors during drug subpackage and improve patients' medication safety.

Objective To analyze the value of three-dimensional computed tomography (CT) reconstruction imaging for the diagnosis and treatment of congenital scoliosis. Methods 76 patients with congenital scoliosis were examined with X-ray of total spine and three-dimensional CT reconstruction, and the results were analyzed. Compared with X-ray film, the findings with the CT imaging were classified into three groups: Group Ⅰ, no supplementary useful information was obtained; Group Ⅱ, further confirmation of findings which were unclear or ambiguous on X-ray film, with improved visualization and comprehension of the type of the deformity; Group Ⅲ, substantial new information was obtained. Results Group Ⅰ: 11 (14.5%) patients, without supplementary useful information obtained with three-dimensional CT reconstruction imaging. The patients aged from 2 to 16 years(11.00?10.09 years), and the Cobb angle ranged from 28? to 102?(55.60??21.06?). Group Ⅱ: 49 (64.5%) patients, with confirmatory finding or improved visualization and comprehension of the previously identified deformities obtained with CT imaging. The 49 patients aged from 4 to 28 years (13.53?4.47 years), and the Cobb angle ranged from 20? to 115? (55.41??23.44?). Group Ⅲ: 16 (21%) patients, with substantial new information obtained with CT reconstruction images which was unrecognized with X-ray film. The patients aged from 6 to 16 years (12.88?2.68 years),and the Cobb angle ranged from 37? to 145?(73.19??28.18?). The difference of age of patients between 3 groups was of no significance (P=0.052), but the difference of Cobb angle between 3 groups was significant statistically (P=0.039). Conclusion Three-dimensional and multiplanar reformatted CT imaging allows better visualization and understanding of the deformities of scoliosis, and supplementary useful information may be obtained which was obscure or unrecognized with X-ray film, especially for patients with severe deformities. Its application in clinical practice may contribute to the diagnosis of the type of deformity and the segments involved, as well as the individualized operative planning.

ObjectiveTo evaluate the reasonableness of total mesorectal excision (TME) in the management of rectal cancer. Methods The carcinoembryonic antigen (CEA) level of surgically removed distal mesorectum (3?cm below the tumor),tumor tissue and normal mesocolon was detected by microparticle enzyme immunoassay in 26 rectal cancer patients. Results The CEA level in normal mesocolon was (1.6?1.0)?ng/g, and (62.5?85.2)?ng/g in distal mesorectum(P1?000?ng/g).ConclusionsIn patients with rectal cancer, much higher CEA level in distal mesorectum than in normal mesocolon might indicate distal mesorectal dissemination. It is necessary to routinely perform TME in the surgical management of middle and lower rectal cancer.

Objective: To optimize the preparation process of tetrandrine dropping pills (TDP) and investigate the in vitro dissolution rate. Methods: Plackett-Burman experimental design was used to screen the critical factors in the preparation process of TDP from the ratio of matrix, ratio of matrix to drug, dropping temperature, dropping rate, dropping distance, and condensate temperature. The forming rate and weight variation of TDP were used as the evaluation index, the parameters in the preparation process of TDP were optimized by using the Box-Behnken response surface method. Moreover, the in vitro dissolution rate of TDP was compared with tetrandrine tablets by rotating basket method. Results: The Plackett-Burman experimental design results showed that the ratio of matrix, dropping temperature and condensate temperature had a significant effect on the forming rate of TDP. The optimum preparation parameters by Box-Behnken response surface method were as follows: the ratio of matrix was 2.6∶1, dropping temperature was 82.4 ℃ and condensation temperature was 7.5 ℃ with high forming rate, good roundness, stable weight, and fast drug dissolution rate of TDP. Conclusion: The quality of TDP by experimental design method can meet the requirements and can be further amplified.

Aim To investigate the relationship be-tween the depression-like behaviors of rats induced by chronically unpredictable stress( CUS) and the protein expression of tumor necrosis factor alpha( TNF-α) , in-dole-2 , 3-dioxygenase ( IDO ) and 3-hydroxyl amino acid oxygenase( HAAO) . Methods Thirty male Spra-gue Dawley( SD) rats were randomly divided into con-trol group and model group. CUS plus solitary condi-tion were used to establish the depression model. The open field test ( OFT ) and the force swimming test ( FST ) were used to evaluate the depression-like behaviors of rats ;Western blot was used to determine the protein expressions of TNF-α, IDO and HAAO in the prefrontal cortex and hippocampus of rats. Results Model group rats showed obvious depression-like be-haviors with increasing immobile time in FST ( P <0. 01) and decreasing locomotive activity in OFT( P<0. 01 ) , and up-regulating the protein expression of TNF-α, IDO and HAAO in the prefrontal cortex and hippocampus significantly ( P <0. 05 ) , compared with control group rats. Conclusion The depression-like behaviors of rats induced by CUS may be associated with the activation of IDO-HAAO pathway mediated by TNF-α.

Platelet-rich plasma (PRP) is a concentrated source of autologous platelets after centrifugation, being used widely in plastic surgery and oral-maxillofacial surgery. Recent studies have showed that PRP can improve bone repair, vasculogenesis, and soft tissue repair. Composite of PRP and stem cells is applied in the field of orthopedics and tissue engineering. As a matter of fact, PRP has become a hot research topic. In addition, PRP plays an important role in the healing of chronic wound. This paper briefly introduces the main components of PRP and its clinical application, the mechanism for bone healing and soft tissue repair, as well as the latest research achievement and discussion in the shortcoming of PRP in clinical application.
