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.

Objective To analyze the effectiveness of chronic disease management among suburb residents to secure an optimal health management model. Methods Since 2002, physical examinations had been conducted for rural residents aged≥40. Hypertensive patients detected on health check received medical evaluation and risk factor intervention. Results The incidence of high blood pressure decreased from 26.57% in 2002 to 11.99% in 2007-2008. The mortality of cerebrovascular disease declined from 68.00% to 5.26%. The incidence, disability rate, and death rate of hypertension related-stroke were also significantly reduced. Conclusion Primary healthcare center-based chronic disease screening, along with the health management network, can largely decrease the incidence, disability rate, and mortality of stroke associated with high blood pressure.

Under the influence of Chinese medicine scientization, Chengjiang Acupuncture School, which was originated in the Republic of China (1912 - 1949), has also undergone a series of scientific practice. The Chengjiang School established scientific research, education and medical organizations such as the Research Society of China Acupuncture-Moxibustion, China Acupuncture-Moxibustion School, Training School of China Acupuncture-Moxibustion and Sanatorium of Acupuncture-Moxibustion. Zhenjiu Zazhi (Journal of Acupuncture-Moxibustion) was established, and monographs and textbooks such as Zhongguo Zhenjiu Zhiliaoxue (Therapeutics of Chinese Acupuncture-Moxibustion) and Zhongguo Zhenjiuxue Jiangyi (Lectures on Chinese Acupuncture-Moxibustion) were published. Meanwhile, based on clinical practice, large members of acupuncture personnel with scientific literacy emerged. Therefore, it is held that the scientization of Chengjiang School has performed a profound influence on the development of modern acupuncture-moxibustion.

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.

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 observed the immigration and proliferation of Schwann cells in acellular xe- no-nerve graft in rats.Methods The sciatic nerves on the right side of the rats were exposc.d and 0.8cm long segments of the nerves were removed from the mid-thigh level and replaced by 1.0cm long rabbit nerves made acellular through chemical extraction.After 4 months,the immigration and proliferation of Schwann cells in the graft were revealed by HE staining,S-100 immunohistochemieal staining and transmission electromicro- scope.Results In the rats repaired by acellular nerves,regenerated axons upgrow into the graft,and a- round regenerated axons there were abundant cells aligned,the cytoplasm of which were S-100 immunoreac- tive.Electromicroscope observing showed that regenerated axons were surrounded by myelin formed by the mi- grated cells reoccupied the acellular segments.Conclusion The host Schwann cells can immigrate into rab- bit nerve grafts made acellular through chemical extraction and form myelin enwrapping regenerated axons in rats.

OBJECTIVETo analyze effects of fracture of processus styloideus ulnae on prognosis in the treatment of distal radial fracture of type C according to AO classification.

METHODSThis was a retrospective case-control study, and the information was got ten through case evaluation and follow-up, including sex, age, patient satisfaction, Gartland & Werley score and radiographic score. There were 76 patient treated with open reduction and plate fixation in People's Hospital Affiliated to Peking University from July 2006 to July 2011. All the patients were divided into two groups: no combination with fracture of processus styloideus ulnae (group A, 56 cases), combination with fracture of processus styloideus ulnae (group B, 20 cases). The patients in group A and B were treated with open reduction and internal fixation; however the fracture of processus styloideus ulnae was not fixed. The indexes such as clinical data, bone grafting, joint movement, Gartland & Werley score and radiographic score were compared between two groups.

RESULTSThe ulnaris pain of patients in group B was more obvious than that in group A. The local VAS, palmar and dorsal flexion degree of wrist joint, motion VAS, patients satisfaction score, radial and ulnar deviation degree, pronation and supination of forearm degree, Gartland & Werley score and radiographic score were separately 0.1 ± 0.1, (51.1 ± 1.9)°, (60.2 ± 1.9)°, 0.6 ± 0.1 (23.1 ± 0.9)°, (28.7 ± 1.3)° (81.5 ± 2.6)°, (68.2 ± 2.7)° 1.9 ± 0.3, 89.6 ± 12.3 in group A; and separately 0.3 ± 0.3, (51.4 ± 2.3)°, (66.6 ± 1.7)°, 0.5 ± 0.2, (24.5 ± 2.0)°, (26.9 ± 1.8)°, (80.3 ± 2.5)°, (70.3 ± 3.7)°, 1.2 ± 0.4, 92.5 ± 7.5 in group B; there were no statistical differences in above indexes between two groups.

CONCLUSIONWhether the distal radial fracture with a concomitant unrepaired ulnar styloid fracture or not exerts no influence on mainly outcomes including function, radiography and motion of the wrist.
