Objective To study computed tomography (CT) in evaluating prognosis for hypoxic ischemic encephalopathy (HIE) in infants. Methods Eighty-five infants diagnosed as HIE underwent CT one week,two months,three to six months and one to one and a half years after birth,respectively. At the same time,neonatal behavior neurological assessment (NBNA) was made at 12 to 14 days after birth. Development quotient (DQ) was used to evaluate their prognosis at age of 1 to 1.5 years. Results Rate of poor prognosis was 40.9% (9/22) in the infants with severe HIE by CT and 5.7% (3/52) in those with moderate HIE within one week after birth. Rate of poor prognosis was 60.0% in the infants with abnormal CT at age of two months. There was no significant difference in their prognosis for infants of moderate HIE with NBNA scores greater than or equal to 35 and less than 35,12 to 14 days after birth. And,72.7% (8/11) of the infants with severe HIE by CT with NBNA less than 35 showed little recovery at 12th-14th days after birth. Conclusions Combination of CT and clinical follow-up with NBNA score one month after birth could play an important role in the evaluation for therapy regime,length of treatment and prognosis in the infants with HIE.

Objective Based on the published articles,this paper aims to study the pattern and probability of lymph nodes metastasis in nasopharyngeal carcinoma (NPC) and establish a radiotherapy standard for selecting and delineation of clinical target volume of neck lymphatics for NPC patients with N0 or N1.Methods Clinical trials about NPC by MRI as the main or only diagnostic imaging way were collected and extracted from database,such as WanFang,CBM,PubMed,Cochrane Library.Statistical analyses were performed using Stata software,version 12.0.Results Twenty-one clinical trials from 963 original articles were included in this analysis.The most commonly involved regions included retropharyngeal (67％) and level Ⅱ lymph nodes (71％).The overall probability of levels Ⅲ,Ⅳ and Ⅴnodal involvement were 37％,14％ and 21％,respectively.Low-risk node groups included levels ⅠA,ⅠB,Ⅵ nodes,and the rates of lymph node metastasis were 0,2％,2％ and 1％,respectively.Nodal metastases followed an orderly pattern of top-down,and the probability of skip metastasis between levels varied between 0.5％ ～7.9％.Conclusion Lymph node metastasis in NPC follows a predictable and orderly pattern.The rarity of metastasis in certain nodal groups andskip metastasis suggest that reduced treatment volume is feasible in conformal radiotherapy for NPC patients with No or N1.

Methods Effects of LAEPS on immunity were investigated by delayed type hypersensitivity reaction, haemolytic plaque assay and macrophage function assay in mice. Results LAEPS ip 7～8 day promoted delayed type hypersensitivity reaction, increased haemolytic plaque and enhanced macrophage function in a dose-dependent manner.Conclusion LAEPS is able to enhances immunity.

Objective: To compare the efficacy of different treatment protocols in treating transient synovitis of the hip (TSH) in children and to optimize the clinical treatment strategy for this condition. Methods: Ninety kids with TSH were divided into a control group, a chiropractic group and a chiropractic plus foot bath group using the random number table method, with 30 cases in each group. The control group was treated with conventional traction; the chiropractic group was given chiropractic treatment based on the control group; the chiropractic plus foot bath group was given Chinese medicine foot bath based on the chiropractic group. Traction and foot bath were conducted once daily while chiropractic was done once every other day, all with 14 d as a treatment course for a total of two courses. Changes in the visual analog scale (VAS) score and range of motion (ROM) of the hip joint in the three groups were observed, and the efficacy was compared. Results: The total effective rate was 93.3％ in the chiropractic plus foot bath group, versus 76.7％ in the chiropractic group and 66.7％ in the control group, and the total effective rate was notably higher in the chiropractic plus foot bath group than in the other two groups (both P<0.05). Respectively after the first and second treatment course, the VAS score decreased significantly in each of the three groups compared with that before treatment (all P<0.01), and the ROM of the hip joint in flexion increased significantly (all P<0.01). After two treatment courses, the VAS score was lower in the chiropractic plus foot bath group than in the other two groups (both P<0.05), and its ROM of the hip joint in flexion was larger than that in the other two groups (both P<0.05). Conclusion: Based on traction, chiropractic plus Chinese medicine foot bath can effectively reduce pain and improve motor function of the hip joint in treating TSH.

BACKGROUND:Semaphorin7A (Sema7A) is a kind of cel surface protein, which can promote the fusion of osteoclasts and the migration of osteoblasts at the same time, affecting the dynamic balance of the bone. It is speculated that Sema7A siRNA may inhibit osteoblast apoptosis induced by titanium particles. OBJECTIVE:To study the effect of Sema7A on the preosteoblast activity inhibited by titanium particles. METHODS:Mouse MC3T3-E1 preosteoblasts at passages 6 and 7 were divided into four groups: in blank control group, MC3T3-E1 cels were cultured alone; in standard control group, cel were cultured with titanium particles; in experimental groups 1 and 2, the cels were cultured with titanium particles+Sema7A overexpression plasmids and titanium particles+Sema7A siRNA, respectively. Apoptotic rate of MC3T3-E1 cels was detected by flow cytometry; the mRNA expression of bone sialoprotein, osteocalcin and type I colagen was detected by Q-PCR; western blot assay was adopted to detect the protein expression of bone sialoprotein, osteocalcin and type I colagen; alizarin red calcium nodule staining was taken to detect the degree of osteoblast mineralization. RESULTS AND CONCLUSION:The expressions of bone sialoprotein, osteocalcin and type I colagen were decreased in the standard control group and experimental group 1, but these expression were significantly increased in the experimental group 2 compared with the standard control group (P < 0.05). Flow cytometry results suggested that the apoptotic rate of osteoblasts in the experimental group 1 was significantly higher than that in the other groups (P < 0.05), and the apoptotic rate in the experimental group 2 was lower than that in the standard control group (P < 0.05). Alizarin red staining showed that there were no obvious mineralized nodules in the experimental group 1, but mineralized nodules formed in the experimental group 2. In brief, the genetic interference technique that inhibits the activity of Sema7A can interfere the process of mouse MC3T3-E1 preosteoblast differentiation inhibited by titanium particles, and thus provide a feasible way for the clinical treatment of wear particles-induced osteolysis using biotechnology.
