[Objective]To explore the surgical management and its results of intercondylar fracture of humerus through approach of osteotomy of olecranon(AOO) with dual anatomical steel plate DASP.[Method]From July 2002 to March 2006,26 patients of intercondylar fracture of humerus were treated surgically through AOO,and the fracture was reduced and fixed with DASP.The patients were 19 males and 7 females with a mean age of 35 years (range 15～46 years),According to Riseborough and Radin classification,type Ⅱ fracture was found in 6 cases,type Ⅲ in 18,type Ⅳ in 2.Early rehabilitation exercises was taken.[Result]Twenty-five fractures were satisfactory reduced but one not too good,none had incision infection,injuries of the ulnar nerve.Twenty-two patients were followed up from 6 months to 19 months(average 13.5 months),of these 22 patients,all the osteotomies healed in 17 weeks averagely(range 14～24 weeks) and the injuried ulnar nerve recovered completely.The function of the elbow(according to Cassbaum scale) showed excellent in 5 cases,good in 13,fair in 3 and poor in 1.the good-excellent rate was 81.8%.[Conclusion]The technique of DASP for the treatment intercondylar fracture of humerus through transolecranon approach offers many advantages,such as sufficient exposure easy to get anatomical reduction,stable fixation and earlier exercise.

Purpose: To evaluate the clinical efficacy of V AD regimen in the treatment of newly diagnosed stage III multiple myeloma (MM). Methods:26 patients with newly diagnosed stage Ⅲ multiple myel oma were treated with VAD regimen. VAD solution consisted of vincristine (VCR) , doxorubicin(ADR),dexamethasone (Dex).Three continuous treatments in one treatm ent course were considered evaluable.Evaluation included results of serum myelom a protein(M-protein); renal function; proteinuria of 24-hours; bone marrow ; per ipheral blood et al.The side reactions were recorded. The clinical efficacy eval uation was divide into complete response(CR),partial response(PR),minimal-respon se(MR), no change(NC) , plateau progression.Results:5 cases achieved CR(19.3%), 13 cases PR(50%),6 case s MR (23%), 2 cases no change (7.7%). Overall response rate was 92.3%, median su rvival duration was 7 to 84 months (29.6?17months). Conclusions:Achieved marked clinical efficacy with VAD agent in newly diagnosed stage III multiple myeloma. Especially,the patients with renal failure and serious clinical manifestation improved rapidly and significantly.

To explore the effect of high glucose on the NF-κB/IκB signal pathway in cultured rat glomerular mesangial cells. The results showed that high glucose increased the degradation of IκB-α and the translocation to nucleus of NF-κB. These changes could be reverted mostly by MG132, a proteasome inhibitor. It suggests that the activation of the NF-κB signal pathway by high glucose concentration may probably be via the ubiquitin-proteasome pathway.

ObjectiveTo investigate the characteristics of Kienbock's disease in patients older than 60 years of age.MethodsGender, age at onset, affected side, dominant hand, occupation, and clinical results in 7 wrist of 7 elderly patients with Kienbock's disease were investigated.ResultsKienbock's disease in elderly patients commonly was observed in the dominant hand of manual works and was found more often in women than in men. The age at onset was from 60 to 70. Although radiographic examination revealed development of carpal collapse in all patients.ConclusionThe etiologic factors different from conventional ones might have played a role in aged patients with Kienbock's disease, surgical and rehabilitation treatments are good or excellent.

Objective To investigate the safety of rituximab combination chemotherapy in the treatment of B-cell non-Hodgkin' s lymphoma (B-NHL) complicated with hepatitis B virus (HBV) infection,and assess the incidence of HBV reactivation reduced by prophylactic lamivudine.Methods A retrospective study of HBV-related markers,HBV-DNA and liver function was performed before and after rituximabcontaining treatment in B-NHL patients.Thirty nine B-NHL patients with HBcAb(+)/HBsAb(-) were divided into prophylactic group (14 cases) and control group (25 cases).The incidences of HBV reactivation,functional damage of liver were measured.Results Among the 108 B-NHL patients who received rituximab combinatio nchemotherapy,15 (13.89 ％) were HBsAg (+) and 39 (36.11％) HBsAg (-) / HBcAb (+).Of the 15 HBsAg (+)patients,2 (13.3 ％) experienced reactivation of HBV.The prevalence of HBV reactivation was 7.7 ％(1/13) in patients who received prophylactic antiviral treatment and 50 ％ (1/2) in those who did not receivelamivudine.Among the 39 HBsAg (-) / HBcAb (+) patients,3 cases (7.7 ％) experienced reactivation of HBV.The prevalence of HBV reactivation was 0 in patients who receivcd prophylactic lamivudine treatment and 12 ％ (3/25) in those who did not receive this antiviral drug.Conclusion Prophylactic lamivudine before rituximab combination chemotherapy can reduce HBV reactivation obviously.

Objective To analysis long-term effects and safety of arsenic trioxide (ATO)-based induction and maintenance therapy in newly diagnosed acute promyelocytic leukemia (APL). Methods Retrospective analysis induction remission and post-remission treatment of 62 newly diagnosed APL patients was performed. These cases were followed up for 5 and 7 years. Results The complete remission (CR) rate was similar in ATO/all-trans retinoic acid (ATRA) induction group and ATRA/chemotherapy induction group.However, the former group has the shorter time to CR. The negative rate of PML-RARα fusion gene after induction without ATO was less than that of ATO group (86.2 % vs 56.3 %, P ＜0.05). After CR, the 5-year overall survival (OS) between ATO-base rotation maintenance group and chemotherapy-base rotation maintenance group showed that the former was (94.4±5.4) %, the latter is (45.5±10.2) %; 7-year OS was (52.5±23.7) % and (27.3±9.3) %; 5-year disease free survivals (DFS) was (94.7±5,5) % and (41.3±10.1) %; 7-year DFS was (52.6±23.7) % and (27.5±9.4) %. There was significant different in 5-year or 7-year OS and DFS between two groups (P ＜0.05). The relapse rates of the two groups in post-remission treatment were 14.7 % and 37.0 % (P ＜0.05). Conclusion ATO combined ATRA induction therapy increased the negative rate of PML-RARα fusion gene. ATO-base rotation maintenance improved long-term outcome and decreased the rate of relapse. Furthermore, ATO appeared to be generally safe and well tolerated.

Objective To probe deficits in visuospatial attention using an attention network test (ANT) in patients with frontoparietal network lesions. Methods The ANT was used to measure the alertness, orienting and executive control abilities of 25 patients with local brain lesions, including 13 with frontal and 12 with parietal damage. Their results were compared with those of health adults. Results During ANT tasks, the patients' responses were significantly slower on each cue and target condition than controls', and showed deficits in their alerting and orienting networks. The efficiency of executive control was impaired in patients with frontal lesions, but increased with parietal lesions. Conclusions These findings suggest that the frontoparietal network is involved in alerting and orienting, but the executive control function may be selectively associated with the frontal lobe. ANT is an efficienttool for studying visual attention and cognition.

OBJECTIVETo explore the protection of high intensity microwave radiation on hypothalamo-pituitary-adrenal axis (HPAA) activity and hippocampal CA1 structure in rats and the protectiveeffect of Qindan Granule (QG) on radiation injured rats.

METHODSTotally 48 Wistar rats were randomlydivided into 8 groups, i.e., the normal control group, post-radiation day 1, 7, and 10 groups, 7 and 10days prevention groups, day 7 and 10 treatment groups, 6 in each group. Rats in prevention groups wererespectively administered with QG liquid (1 mL/100 g, 4. 75 g crude drugs) for 7 days and 10 days bygastrogavage and then microwave radiation. Then preventive effect for radiation injury was statisticallycalculated with the normal control group and the post-radiation day 1 group. Rats in treatment groupswere firstly irradiated, and then administered with QG liquid (1 mL/100 g, 4.75 g crude drugs). Finally preventive effect for radiation injury was statistically calculated with the normal control group, post-radiation day 7 and 10 groups. Contents of corticotrophin releasing hormone (CRH), beta endorphin (beta-EP), adrenocorticotropic hormone (ACTH), and heat shock protein 70 (HSP70) were detected. Morphological changes and structure of hippocampal CA1 region were observed under light microscope.

RESULTSCompared with the normal control group, contents of CRH and beta-EP significantly decreased in each radiation group. Serum contents of ACTH and beta-EP significantly increased in post-radiation day 1 and 7 groups (P < 0.05). Compared with radiation groups, beta-EP content in serum and pituitary significantly increased, and serum ACTH content significantly decreased in prevention groups (P < 0.05). Pituitary contents of CRH and beta-EP significantly increased in prevention groups. Serum contents of ACTH, beta-EP, and HSP70 were significantly lower in day 7 treatment group than post-radiation day 7 group (P < 0.05). Morphological results showed that pyramidal neurons in the hippocampal CA1 region arranged in disorder, with swollen cells, shrunken and condensed nucleus, dark dyeing cytoplasm, unclear structure. Vessels in partial regions were dilated with static blood; tissues were swollen and sparse. In prevention and treatment groups pathological damage of hippocampal CA1 region was obviously attenuated; neurons were arranged more regularly; swollen, pycnotic, or deleted neuron number were decreased; vascular dilatation and congestion was lessened.

CONCLUSIONQG could affect HPAA function and activity of high intensity microwave radiated rats, showing certain preventive and therapeutic effects of microwave radiated rats by adjusting synthesis and release of partial bioactive peptides and hormones in HPAA, improving pathological injury in hippocampal CA1 region.
