Results The cartilaginous spine column began to form at E13.5.The primary ossification center was observed at E15.5,then the osteogenesis expanded and extended to both sides.HIF-1? mRNA began to express at E13.5,and more significantly at E14.5(P

Objective: To explore the clinicopathologic features of non-Hodgkin' s lymphoma (NHL) patients seen in our hospital in the recent ten years and to discuss the relationship between clinical data and the prognostic factors. Methods: The clinical and pathological features of 1,012 NHL cases were retrospectively analyzed. Results: The main pathological subtypes included 346 (34.1%) cases of diffuse large B-cell lymphoma (DLBCL), 185 (18.3%) cases of peripheral T-cell lymphoma (PTCL), 97 (9.6%) cases of follicular lymphoma (FL), 94 (9.3%) cases of extranodal mucosa-associated lymphoid tissue (MALT), 62 (6.1%) cases of nasal NK/T-cell lymphoma and 47 (4.6%) cases of T-lymphoblastic lymphoma. There were 619 (61.2%) cases classified as nodal lymphoma and 393 (38.8%) cases classified as extranodal lymphoma. For the whole group, the 5-year overall survival (OS) rate was 45.8%. The univariate analysis showed that the clinical stage, performance status (PS), B-symptom, age, tumor size, the serum lactate dehydrogenase (LDH) level, the number of extranodal involvement and IPI were correlated with prognosis of NHL(P＜0.05). The multivariate analysis showed that the source of T cells, Ⅲ/Ⅳ clinical stage, IPI (3～5) and increased LDH were correlated with poor prognosis (P＜0.05). Conclusion: The incidence of NHL in middle-aged people is relatively higher. Extranodal lymphoma and B-cell lymphoma are more frequent in Xinjiang. Immunophenotypes, clinical stages, IPI and the level of LDH expression are closely correlated with prognosis of NHL.

Objective To investigate the efficacy of ambroxol combined with penehyclidine hydrochloride for prevention of pulmonary complications after surgery due to acute abdomen in pediatric patients with upper respiratory tract infection.Methods Fifty pediatric patients with acute abdomen complicated with respiratory infection,of ASA physical status Ⅰ or Ⅱ,aged 6 months-5 yr,were randomly divided into test group (group A) and control group (group B),with 25 cases in each group.Immediately after admission to the operating room,ambroxol 1 mg/kg and penehyclidine hydrochloride 0.02 mg/kg were injected intravenously in group A,and atropine 0.02 mg/kg was given in group B.Extubation time and development of laryngospasm,bronchospasm and hypoxemia were recorded.The patients were followed up for 72 h after surgery and the development of postoperative pulmonary complications was recorded.Results Compared with group B,the incidence of hypoxemia and pulmonary complications was significantly decreased,and extubation time was shortened in group A.Conclusion Ambroxol combined with penehyclidine hydrochloride can prevent pulmonary complications after surgery due to acute abdomen and is helpful for prognosis in pediatric patients with upper respiratory tract infection.

The aerolysin genes (aerA) of BZ and NK isolates were cloned and sequenced. The sequence analysis showed that the partial aerA of BZ and NK isolates consisted of 1393 bp, encoding a protein of 464 amino acids. The similarity of nucleotide and amino acid sequences of aerA between BZ and NK isolates was 97.6% and 98.3% respectively. The nucleotide sequence of aerA of BZ strain exhibited 71.6% to 97.5% homology with other Aeromonas isolates, and the amino acid sequence exhibited 68.0% to 98.9% homology. The phylogenetic tree based on aerA nucleotide sequences from Aeromonas isolates was constructed with neighbor-joining method. It showed that there were three branches of aerolysin genes, and a close relation- ship among Aeromonas hydrophila isolates which were clustered into the same branch.

Objective: To observe the clinical efficacy of spleen-invigorating and qi-benefiting pediatric massage (tuina) for treating recurrent respiratory tract infection in children with cerebral palsy due to qi deficiency of spleen and lung. Methods: A total of 70 children with cerebral palsy who suffered from recurrent respiratory tract infection due to qi deficiency of spleen and lung were randomized into an observation group and a control group by the random number table method, with 35 cases in each group. Both groups were treated with conventional rehabilitation training, while the observation group was given additional spleen-invigorating and qi-benefiting pediatric massage, and the control group additionally took oral Yu Ping Feng granule. The clinical efficacy was evaluated by the total effective rate, traditional Chinese medicine (TCM) symptom score, and serum levels of immunoglobulin (Ig) A, IgM and IgG. Results: The difference in total effective rate between the two groups after treatment was statistically significant (P<0.05). After treatment, the TCM symptom scores in both groups decreased to varying degrees than those before treatment, and the intra-group differences were statistically significant (all P<0.01); the differences in the scores of various TCM symptoms between the two groups were statistically significant (all P<0.05). After treatment, the levels of IgA, IgM and IgG of the children in both groups increased to varying degrees, and the intra-group differences were statistically significant (all P<0.05). The between-group differences in the IgA, IgM and IgG levels after treatment were statistically significant (all P<0.05). Conclusion: Spleen-invigorating and qi-benefiting pediatric massage can effectively treat recurrent respiratory tract infection due to qi deficiency of spleen and lung in children with cerebral palsy, relieve the clinical symptoms and improve immune function, and thus is worthy of clinical promotion and application.

Objective:To investigate the clinical significance of Bcl-6, c-myc gene abnormalities in Xinjiang Uygur and Han dif-fused large B-cell lymphoma (DLBCL) subtypes. Methods:Bcl-6, c-myc gene was detected by fluorescence in situ hybridization in 233 patients with DLBCL . A relationship was observed among Bcl-6, c-myc gene translocation, and clinical data in DLBCL patients. In addition, a difference was observed among Bcl-6, c-myc gene translocation, and different ethnic groups in different subtypes of DLB-CL. Results:Among the 233 patients, 51 cases (21.89%) had rearranged Bcl 6 gene, and 39 cases (16.74%) had rearranged c-myc gene. Bcl-6 gene translocation and expression was related with age, gender, disease location, clinical stage, and LDH levels (P>0.05), but was not related with nationality , international prognostic index score, extranodal involvement, B symptoms, DLBCL subtypes, and recent efficacy (P<0.05);c-myc gene translocation and expression was related with age, gender, disease location, clinical stage LDH levels, and DLBCL subtypes (P>0.05), but was not related with nationality, IPI score, extranodal involvement, B symptoms, and recent effica-cy (P<0.05). In the Uygur and Han GCB groups, Bcl-6, c-myc gene translocation showed no significant difference (P>0.05). By con-trast, in the Uygur and Han non-GCB groups, Bcl-6, c-myc gene translocation showed significant difference (P>0.05). Conclusion:Bcl-6, C-myc gene translocation was related with age, gender, disease location, clinical stage, and LDH levels. Bcl-6 gene translocation was also correlated with different subtypes of DLBCL.
