OBJECTIVETo study the effect of Astragali Radix on the denervated tibial muscle atrophy in rats, and discuss its mechanism.

METHODTotally 60 SPF-grade Sprague-Dawley rats were selected in the common peroneal nerve crush model, and then randomly divided into 6 groups: Astragali Radix high-dose, medium-dose, low-dose groups, the Mecobalamin group, the model group, and the sham operation group. They were administered with drugs after the operation. At 18 d, the pathological section staining and morphological analysis were performed. The wet-weight ratio and section area of tibial muscles were also measured. The real-time fluorescence quantification was adopted to detect the differential expression between Angptl4 and PI3K genes.

RESULT(1) Wet-weight ratio: The wet-weight ratio in Astragali Radix high-dose, medium-dose groups was much higher than that in the model group (P < 0.05 or P < 0.01). (2) Section area: The sham operation group was higher, with regular morphology; Whereas the model group showed significant decrease, with chaotic structure and obvious connective tissue proliferation; Astragali Radix groups and the mecobalamin group showed relatively small section areas, with chaotic structure and unobvious connective tissue proliferation. Compared with the model group, Astragali Radix groups showed significant increase (P < 0.01). (3) Motor end plate: The sham operation group was in uniform brownish black color and oval or round shape; Astragali Radix medium-dose and high-dose group and the mecobalamin group showed rough line edges; Astragali Radix medium-dose and low-dose groups and the model group showed decline in the number, with irregular morphology, rough line edges and a light color. (4) Angptl4 and PI3K: Compared with the model group, the Astragali Radix high-dose group showed significant increase (P < 0.05).

CONCLUSIONAstragali Radix has a significant effect in preventing and treating denervated tibial muscle atrophy. It may delay the muscle atrophy by increasing Angptl4 and PI3K gene expressions.

AIM: To evaluate the effect of flavored Siwu granules in the clinical adjuvant treatment for phlegm and blood stasis mutual junction retinal vein occlusion.
METHODS: Sixty patients (60 eyes) were randomly divided into treatment group and control group, both with retinal laser photocoagulation and intravitreal injection of triamcinolone acetonide, but the treatment group used flavored siwu granules. Vision, fundus change, fundus fluorescein angiography, clinical syndrome of traditional Chinese medicine ( TCM ), hemorheology examination and safety assessment were evaluated before and 8wk after treatment.
RESULTS: At 8wk after treatment, there were differences on vision improvement, retinal circulation time, whole blood low shear viscosity and total efficient rate of clinical syndrome of TCM, compared with control group(P<0. 05).
CONCLUSION: Flavored siwu granules adjuvant for phlegm and blood stasis mutual junction retinal vein occlusion can improve visual acuity and reduce the eye complications.

Objective To explore the relationships between serum adiponectin,IL-6 and hypoxic-ischemic encephalopathy(HIE) degree in newborn infant.Methods Enzyme-linked immunoabsorbent assay was used to detect the serum adiponectin and IL-6 in 58 neonatal HIE and 26 neonates without HIE.And all the data were processed by SPSS 10.0 software.Results The level of serum adiponectin in moderate and severe HIE at acute stage were significantly lower than that of mild and control groups(Pa0.05).The level of serum IL-6 in moderate and severe HIE at acute stage were significantly higher than that of the mild and control groups(Pa0.05).The level of adiponectin were significant negative correlation with IL-6(r=-0.852 P

Objective To explore the diagnosis and curative effect of phenylketonuria(PKU) in Gansu.Methods Fifty-nine thousand nine hundred infants and 118 borderline cases were screened from Oct.1999 to Dec.2006.Three drops of venous blood was collected from the exterior or interior part in the heel,and trickled the venous blood onto the specialized filter paper,which could be formed into 3 bloodstains with the diameter of 0.8-1.0 cm.Phenylalanine(phe) was detected by chemiluminescence method,and PKU was screened by the PKU standard of diagnosis.Infants with PKU had been given low phe food.During the treatment,phe level,physical development and intellectual development were measured regularly.Patients′ body weight,height and head circumference were measured once 1 month.Patients′ intellectual quotient(IQ) were measured every half year(IQ was analyzed by Gesell test).Results were analyzed by SPSS 11.0 software for t test.Results In total,93 patients with PKU were diagnosed and treated.Thirty-six cases were identified by neonatal screening before 3 mouths old.Mental retardation was found in 57 cases before 6 years old.After treatment with low-phe diet,the follow-up for early-treated patients revealed that their physical and mental development were normal,and height,weight and head circumference were in the normal amplitude,and the results of IQ was(92?12)scores.In later treated patients,abnormal behaviors were significantly improved and their developmental quotients were elevated.Before treatment,Gesell value was(57?20)scores;after 12-18 months treatment Gesell value was(70?20)scores.The difference was significant(t=1.705 P
