Hyperphenylalaninemia is a common group of inherited metabolic diseases.It is characterized by the increased concentration of plasma phenylalanine.The metabolism of phenylalanine requires phenylalanine hydroxylase and coenzyme tetrahydrobiopterin.These enzymes cannot function normally if there is any mutation in their encoding genes.Children suffering from hyperphenylalaninemia without promptly treatment may present mental development delay and other serious nervous system sequelae.With the technical improvement of molecular genetics,there have been many progresses in the study of genetic diagnosis,genotype-phenotype correlation and gene therapy of hyperphenylalaninemia.This article reviews the history and classification of hyperphenylalaninemia,the characteristics of gene mutation,the methods of genetic diagnosis,the genotype-phenotype correlation,and the progress of new therapy.

Objective:To study the effect of synthetic antimicrobial peptides on Escherichia coli biofilm.Methods:The test tube method was used to establish the model of Escherichia coli biofilm.The samples were randomly divided into four groups:group A,by adding 4?MIC antimicrobial peptides to the samples,group B,by adding 1?MIC gentamicin to the samples,group C,by adding 4?MIC antimicrobial peptides and 1?MIC gentamicin to the samples,and group D,by adding phosphate buffered saline to the samples as a control.After 6 h the viable bacteria in the biofilm were counted following the method of colony count.The different changes in the biofilm were compared between the treated groups and the control group with scanning electron microscope.Results:The viable bacteria in group C were significantly decreased compared with the other three groups(P≤0.05).While compared with group D,the viable bacteria were decreased in group A and group B(P≤0.05).From the graph of scanning electron microscope the integrity of the Escherichia coli cell membrane was disrupted in group A and C.Conclusion:The results suggest that the killing effect of combination of antimicrobial peptides with gentamicin is significantly increased.

Sonic Hedgehog (SHH) signaling pathway not only plays key roles in embryonic development,but also functions in postnatal development and maintenance of tissue/organ integrity and function.In recent years,it has been found that the SHH signaling pathway was abnormally activated in some lung diseases,which suggested that the SHH signaling pathway may play a part in the development of some lung diseases.This article reviewed the potential role of SHH signaling pathway on the embryonic lung development and lung diseases.

BACKGROUND:Several studies have demonstrated that the physiological process of the ovary, including folicle development, maturity, ovulation, corpus luteum formation and regression, is related to the formation of extracelular matrix. However, matrix metaloproteinase 9 and connective tissue growth factors had a close relationship with the formation of extracelular matrix. OBJECTIVE:To investigate the relationship between the expression of connective tissue growth factor and matrix metaloproteinase 9 and polycystic ovary syndrome. METHODS:The female SD rats with regular estrous cycle were randomly divided into control and model groups. The rats in the model group were intragastricaly with letrozole to establish the model of polycystic ovary syndrome, while the rats in the control group were intragastricaly with the same amount of carboxymethyl celulose. When the natural law of estrous cycle of rats in the model group did not exist and consecutive interval appeared, rat serum and ovarian tissues were colected. Rats in the control group were detected by colecting specimen in the interval. RESULTS AND CONCLUSION:Radioimmunoassay and immunohistochemical staining results showed that compared with the control group, the expression of serum luteinizing hormone, serum prolactin levels, connective tissue growth factor in preantral folicles theca cytoplasm, connective tissue growth factors in folicular basement membrane cytoplasm, connective tissue growth factors in albuginea and matrix metaloproteinase 9 in corpus luteum significantly increased (P < 0.05). The contents of folicle stimulating hormone and serum estradiol, and expression of matrix metaloproteinase 9 in folicular basement membrane significantly decreased (P < 0.05). The results indicate that connective tissue growth factors may be related to the excessive growth of smal folicles and ovulation disorders in polycystic ovary syndrome, while matrix metaloproteinase 9 may be related to ovulation disorders in polycystic ovary syndrome.

Objective To compare the efficacy and safety in patients received paravertebral block and epi-dural block for postoperative rehabilitation pain after unilateral ureterolithotomy.Methods 120 ASA Ⅰor Ⅱ patients were randomly allocated into research group (n =60)and control group (n =60).After operation,the research group received paravertebral block performed with peripheral nerve stimulator,the control group received epidural block.All patients received patient -controlled intravenous analgesia (PCIA)in the same time.The operation time,amount of bleeding,postoperative hospitalization time,operation completion,number of press PCIA,occurrence rate of postopera-tive adverse reaction in 48 h,and visual analog scores (VAS)at 4,8,16 and 24 h after surgery were recorded. Results The patients of the two groups were completed the stone surgery,there was no cases of conversion to open surgery.There was no significant difference in operation time,bleeding volume,postoperative hospital stay between the two groups (all P >0.05).But the PCIA times of the research group was (2.14 ±0.45)times,which of the control group was (4.20 ±0.68)times,the difference was statistically significant (t =4.27,P =0.029).The postoperative VAS scores of the research group[4 h (2.68 ±0.480)points,8 h (2.68 ±0.48)points,16 h (2.81 ±0.43) points,24 h (2.88 ±0.49)points]were significantly lower than those of the control group[(3.12 ±0.53)points, (3.37 ±0.58)points,(3.42 ±0.52)points,(3.39 ±0.55)points],the differences were statistically significant (t =2.68,3.13,306,311,all P <0.05).Of the research group,the nausea and vomiting occurred rate (23.33%), hypotension rate (0.00%),skin itching (5.00%),the incidence of decreased muscle strength (0.00%)were significantly lower than the control group(43.3%,31.6%,28.33% and 8.33%),the differences were statistically significant(χ2 =5.40,22.57,11.76,522,all P <0.05 ).Conclusion Nerve stimulator guidance for thoracic paravertebral nerve block for upper ureter incision to take stone surgery patients can significantly reduce postoperative pain and the PCIA analgesia drug dosage and the incidence of adverse reactions.
