Objective The study aimed to observe the clinical effects and the adverse reactions of recombinant mutant human tumor necrosis factor-alpha ( rhu-TNF) on the treatment of malignant pleural effusion ( MPE) induced by lung adenocarcinoma . Methods 70 patients with MPE caused by lung adenocarcinoma hospitalized in our department were chosen as the research objects . After conventional drainage of pleural effusion , the patients were divided into two groups according to the weight , respectively receiving intra pleural injection of 2 000 000 units and 3 000 000 units of rhu-TNF, followed by the observation of clinical effects and adverse reac-tions.A further retrospective analysis were made on the effects of dexamethasone injected before operation on clinical effects and ad -verse events. Results The effective rates of 2 000 000 unit group and 3 000 000 unit group were respectively 75.68%and 87.88%(P=0.23), with no statistical difference.The adverse reactions in the group of patients being injected dexamethasone before operation significantly reduced(P=0.021) and the use of dexamethasone had no influence on the efficacy of rhu-TNF ( P=0 .486 ) . Conclusion Rhu-TNF is a safe drug with high efficiency in the treatment of MPE induced by lung adenocarcinoma , and the efficacy and safety of re-peated application in clinic still need more supporting data .

OBJECTIVETo evaluate percutaneous reduction by Kirschner pin and internal fixation with cancellous screw and plate through minimal incision at the lateral side of heel for the treatment of intra-articular displacement fracture of calcaneus.
METHODSFrom September 2009 to June 2012, 80 patients with close intra-articular displacement fractures of calcaneus were divided into treatment group and control group. There were 40 patients in the control group, including 21 males and 19 females, ranging in age from 23 to 64 years old, averaged (39.1 +/-11.7) years old; and the patients were treated with fixation by compress screws and plates of self-broken type. There were 40 patients in the treatment group, including 24 males and 16 females,ranging in age from 21 to 67 years old, averaged (39.6+/-14.3) years old;and the patients were treated with full thread cancellous screws and plates fixation. The fixation time,intra-operative blood loss and the number of injured medial plntar nerve were compared between the two groups. The Böhler angle, Gissane angle and the correction degree of calcaneal width were measured at 1 year after operation. The internal fixators were taken out after 1 year. The AOFAS ankle-hindfoot score was used to evaluate therapeutic effects.
RESULTSAll the patients were followed up,and the duration ranged from 9 to 32 months, with a mean of 16 months. There were shorter operation time, less injury, satisfactory postoperative Böhler angle and calcaneal width in treatment group compared with control group,which reduced the medial neurovascular injuries, and the plate was easily removed after fracture healing.
CONCLUSIONFull thread cancellous screws and plate fixation for the treatment of calcaneal fractures could get same therapeutic effects as compress screws and plate of self-broken type fixation, and also has follow advantages: shortening the operation time, reducing blood loss, easily to be removed, avoiding the medial neurovascular damage, reducing the incidence of complications.

Objective To evaluate the expression of alpha-methylacyl-coenzyme-A racemase (AMACR,P504s) with immunohistochemical staining in diagnosis of prostate carcinoma. Methods A total of 133 specimens were taken from the patients (mean age,71 years),including 46 cases of prostate carcinoma (PCa) (1 case of stage A,19 cases of stage B,14 cases of stage C,12 cases of stage D;4 cases of gradeⅠ,14 cases of gradeⅡ,28 cases of grade Ⅲ),53 cases of benign prostate hyperplasia (BPH),13 cases of prostate intraepithelial tumor (PIN),9 cases of normal prostate,6 cases of prostatitis,3 cases of metastatic prostate cancer.Two sections of each specimen were made,with 1 stained by hematoxylin and eosin,and the other stained immunohistochemically by a rabbit monoclonal antibody to AMACR (P504s).AMACR staining expression was characterized as negative (score,1), weak (positive) (2), moderate (3) or strong (4). Results In 46 cases of PCa,AMACR staining expression was negative in 2 cases,weak in 1,moderate in 25 and strong in 18,with a mean staining intensity of 3.28 [95% confidence interval (CI), 3.07-3.50]. In 53 cases of BPH, the staining expression was negative in 47 cases, weak in 6, with a mean intensity of 1.11 (95% CI, 1.02-1.20).In 13 cases of PIN, the staining expression was negative in 12, weak in 1, with a mean intensity of 1.08 (95% CI, 0.91-1.24).The score of PCa group was significantly different from those of the latter 2 groups (P

Primary testicular lymphoma comprises 1% to 9% of testicular neoplasms and represents 1% to 2% of all non-Hodg-kin lymphomas. Histologically, the majority of the tumor consists of diffuse large B-cell non-Hodgkin lymphomas that are of intermedi-ate- or high-grade neoplasm. Clinically, the disease typically presents as a painless testicular swelling that develops over a span of weeks to months. B symptoms such as fever, weight loss, and anorexia are present in 25% to 41% of the patients. This tumor is an ag-gressive type, with frequent invasion of the epididymis, spermatic cord, and scrotum, as well as a marked tendency to relapse, especial-ly in the CNS. The treatment is mainly based on orchiectomy (mostly in stages ⅠE and ⅡE) regardless of its association with prophy-lactic irradiation of the scrotum and administration of intrathecal chemotherapy, cyclophosphamide, doxorubicin, vincristine, and pred-nisone regimen chemotherapy plus rituximab (R-CHOP) (stages ⅢE and ⅣE) and radiotherapy. The multi-modality treatment marked-ly improved progression-free and overall survival. We introduce as reference one case that received a multidisciplinary comprehensive discussion in the Department Lymphoma, Tianjin Medical University Cancer Hospital.
