BACKGROUND:Development of neural crest cels, which is regulated by various genes, plays an important role in the formation of central nervous system, heart, craniofacial organs and other tissues. However, the relationship among these genes is unclear. OBJECTIVE:To investigate the molecular regulatory networks involved in the process of neural crest cel development based on a bioinformatic analysis. METHODS:Totaly 500 differentialy expressed genes during the process ofneural crest cel development were obtained from the GEO on-line database. Then the DAVID and STRING on-line databases were used to evaluate the relationship among these genes. RESULTS AND CONCLUSION:Totaly 500 differentialy expressed genes during theprocess of neural crest cel development could be enriched into different subgroups based on the analysis of DAVID database, including “transforming growth factor β signal pathway”, “WNT signal pathway”, “homeobox gene” , “neural crest cel differentiation” and “neural tube development”. Additionaly, 12 genes molecular networks were built based on the analysis of STRING database, such as DLX5, MSX2, SNAIL2, PAX7, SHH, SOX9, NOG, GSC, KAL1, bone morphogenetic protein 5, fibroblast growth factor 8 and WNT3a.These genes exhibited interactions by co-expression, activation and antagonism. Therefore, many genes involved in the process of neural crest cel development were interacted and formed the networks. These findings imply that we should understand these neural crest-related diseases from a holistic view of the signaling pathway and molecular regulatory networks.

Objective To observe the expression of tumor necrosis factor-α(TNF-α)in acute lung injury caused by paraquat(PQ)in rats,and investigate the mechanism of the rhubarb in respect of pmteetive effects.Method PQ intragastrically poisoning at the dose of 50 mg/kg made a model of the acute lung injury in Sprague-Dawley(SD)rats.Totally 144 adult healthy SD rats(72 female,72male)were randomly divided into control group (group A,n=24),poisoned group(group B,n=48),rhubarb treated group(group C,n=48)and the shaln poisoning group(group D,n=24).Rats of group B and group C were poisoned intmgastrically with PQ(50 mg/kg).and rats of group C and group D were intervened intragastrieally with 300 mg/(kg·d)of rhubarb in 15 min-utes.The white blood cells and total cells in bronchoalveolar lavage fluid(BALF)were counted by using a blood cell counting plate and the protein content of BALF was measured by using the way of Lowry in order to calculate the neutmphiks pereentage and lung permeability index.A small portion of left lung was stained with HE to observe the pathological changes and the expression oftumor necrosis factor-α in the rest of the left lung was observed with immunohistochemistry.The data were handled by the analysis of variance and NK method using SPSS 14.0.Re-suits Compared with group A,the lungs of rats mainly showed congestion,edema and leukocytes infiltration in group B,and fibrosis was found onlyt in a few rats.And the rate neutrophils percentage,protein content and lung permeability index in BALF increased(P<0.01).The expression of TNF-α were obviously inereased at 12 hours after PQ poisoning,and immtmohistochemistry score (IHS)was higher,and peaked at 24 hours later(P<0.05),then remained on a high level for a while and sluggishly declined.Compared with group B,the changes of above mentioned were alleviated obviously,and the expression of TNF-α delayed with the less magnitude of increasing an an obvious tendency of less expression.Compared with group B,delayed,lower increasing extent,obviously re-ducing tendency in group C with statistical difference in IHS(P<0.05).Conclusions Rhubarb ameliorates a-cute lung injury caused by PQ poisoning in rats by means of inhibiting the expression of TNF-α in turn to alleviate inflammatory reaction.

Objective To explore the expressions and significances of p 53、bcl-2、Ki-67 and apopto-sis in keratoacanthoma(KA)and well differentiated squamous cell carcinoma (WDSCC).Methods The expres-sions of p53、bcl-2、Ki-67 were detected by immunohistochemical technique in 44 cases of KA and 20 cases of WDSCC.Apoptosis was identified by using terminal deoxynucleotidyl transfers ( TdT) -mediated dUTP -biotin nick and labelling(TUNEL)method.Results The positive expressive rates of p53 in proliferative、mature and re-gressive of KA were 22.23%、26.18% and 6.52%, which was lower than the positive rate of WDSCC (41.82%).Significant differences were found between every period of KA with WDSCC in p 53 expression;The intensity of expression and pattern were similar in KA of Ki -67 and p53.There were a positive correlation be-tween p53 and Ki-67 expression rate(r=0.986,P<0.001).The bcl-2 staining showed weak expression in 1 case in WDSCC and 2 cases in KA ,but only a few positive tumor cells was limited to basal cell layer in KA .The average apoptosis rate in KA was 21.72%,which was apparently higher than in WDSCC (9.925%).There were a negative correlation between the apoptosis rate and proliferation rate of Ki -67(r=-0.824,P<0.001).Con-clusion The proliferation and apoptosis in KA can coexist .However ,the apoptosis will occupy a dominance posi-tion in regressive phase ,which results in the regression of tumor .The expressions of p53、Ki-67 and apoptosis would be a certain significance in differentiated KA and WDSCC .

8. Analysis of effectiveness of greater trochanteric osteotomy approach and K-L posterior approach in patients with type Ⅳ Pipkin fracture
Chinese Journal of Reparative and Reconstructive Surgery 2020;34(10):1258-1262
Objective: To investigate the effectiveness of two surgical approaches in the treatment of type Ⅳ Pipkin fracture. Methods: The clinical data of 15 patients with type Ⅳ Pipkin fracture treated surgically between July 2013 and June 2018 were retrospectively analyzed. According to different surgical approaches, they were divided into group A (8 cases, using K-L posterior approach) and group B (7 cases, using greater trochanter osteotomy approach). There was no significant difference in gender, age, cause of injury, and interval from injury to operation between the two groups ( P>0.05). The incision length, operation time, intraoperative blood loss, hospital stay, fracture healing time, and complications of the two groups were recorded. Hip joint function recovery was evaluated according to Thompson-Epstein functional evaluation system. Results: All the 15 patients were followed up 1-5 years, with an average of 2.5 years. There was no significant difference in operation time between the two groups ( t=14.681, P=0.100); the incision length, intraoperative blood loss, and fracture healing time in group A were all greater than those in group B, and the hospital stay was shorter than that in group B, showing significant differences ( P<0.05). In group A, 1 patient presented hip pain, clasthenia, and limited mobility after operation, 1 patient presented ossifying myositis, 1 patient presented osteonecrosis of the femoral head, 1 patient presented fat liquefaction of incision, and 1 patient presented sciatica, with a complication incidence of 62.5%. Postoperative hip pain occurred in 1 patient and ossifying myositis in 2 patients in group B, with a complication incidence of 42.9%. There was no significant difference in the incidence of complications between the two groups ( χ2=-0.735, P=0.462). At last follow-up, according to Thompson-Epstein functional evaluation system, the results in group A were excellent in 3 cases, good in 2 cases, fair in 2 cases, and poor in 1 case, with an excellent and good rate of 62.5%; in group B, the results were excellent in 4 cases, good in 2 cases, and fair in 1 case, and the excellent and good rate was 85.7%. There was no significant difference in good and fair rate between the two groups ( χ2=-0.990, P=0.322). Conclusion: K-L posterior approach is more convenient in the fracture treatment during operation, but it has greater trauma, greater vascular damage, and more blood loss. The greater trochanter osteotomy approach can better protect the blood supply of femoral head, shorten the operation time, reduce intraoperative blood loss, and reduce postoperative complications. It is an ideal way in the surgical treatment of type Ⅳ Pipkin fracture.
