OBJECTIVETo explore the association between genetic polymorphisms of TGF-beta (TGF-beta) and susceptibility to pneumoconiosis.
METHODSOne hundred and seventeen patients with pneumoconiosis were selected as case. The control group was workers exposed to dust but without pneumoconiosis who had the same sex, nationality, and workshop or work site as case. The differences in the age and cumulative exposure time between the case and control group were not move than five years and two years, respectively. The case matched with the control according to 1:1. Polymerase chains reaction-restriction fragment length polymorphism was used to determine the frequencies of TGF-beta genes in the two groups.
RESULTSThe frequencies of this TGF-beta (-509) genotypes were CC (22.2%), CT (43.6%) and TT (34.2%) in cases, which was significantly different from the control group, respectively (OR = 1.390, P < 0.05). There was no significant difference for frequency of TGF-beta+869 genotypes and allelic between case and control (P > 0.05). The frequencies of the TGF-beta (+915) genotypes in case [GG (70.9%), GC (29.1%)] were significantly different from the control group (OR = 1.455, P < 0.05). The frequency of TGF-beta (+915) * C allele in the case and control was 14.5% and 8.5%, respectively (P < 0.05). The frequencies of carrying TGF-beta (-509) CC and (+915) GG genotypes were 12.8% and 29.9% in case and control. The frequencies of carrying TGF-beta (-509) * T and (+915) * C alleles were 9.8% and 5.1% in pneumoconiosis and control (P < 0.05).
CONCLUSIONSTGF-beta (-509)CC genotype may be the protective factor for the pneumoconiosis. TGF-beta (+915)GC genotype may be a susceptible factor for the pneumoconiosis. The workers of carrying TGF-beta (-509) * T and (+915) * C alleles are more susceptible to pneumoconiosis.

AIMTo observe effect of acute normovolemic hemodilution(ANH) with HAES-balanced solution as diluting agent on levels of cytokines including IL-1, IL-2, IL-6 and TNF-alpha in rabbit serum so as to provide theoretical basis for clinical application.
METHODSA total of 20 healthy adult rabbits were enrolled in the study and randomly divided into two groups (10 rabbits per group), i.e., control group (Group C) and HAES group (Group H). Under anesthesia of the rabbits, we performed incision of trachea, high-frequency jet ventilation and liberation of femoral artery and femoral veins. Group C was free from hemodilution. Group H was injected with dilution (2-fold of blood letting volume) via femoral veins during blood letting of the femoral artery. 6% HAES-steril plus compound solution of sodium lactate, with crystal/gel ratio of 2:1, blood letting volume = TBV x (Ho-Hf)/Hav. All blood was transfused back 60-120 min after blood letting. Venous blood was collected before blood letting (T0) and 30 min (T1), 60 min (T2), 120 min (T3) and 24 h(T4) after blood letting to detect Hb and Hct and measure level of IL-1, IL-2, IL-6 and TNF-alpha in serum.
RESULTSIn Group H, levels of IL-1, IL-2, IL-6 and TNF-alpha in serum were increased from T1 after ANH, reached peak at T3 but showed decrease at T4, with significant difference compared with Group C at T1, T2, T3 and T4 (P < 0.01) and significant difference compared with those before ANH (P <0.01). In Group C, there was no significant difference upon IL-1, IL-2, IL-6 and TNF-alpha in serum at different time points.
CONCLUSIONANH with HAES-balanced solution as diluting agent can up-regulate the levels of cytokines IL-1, IL-2, IL-6 and TNF-alpha in rabbit serum. In the meantime, ANH may arouse eustress with low intensity and short action time, which exerts effect of enhancing immune function of the organisms.

OBJECTIVETo study the significance of cytokine IL-1α and S100β expression in formation and evolution of different types of plaques in Alzheimer's disease.
METHODSThirty-four autopsy cases of Alzheimer's disease encountered during the period from 1982 to 2008 were retrieved from the archival files of Department of Pathology, Beijing Hospital. Tissue blocks were taken from hippocampus for dual immunostaining for IL-1α/Aβ and S100β/Aβ.
RESULTSImmunohistochemical studied for IL-1α/Aβ and S100β/Aβ delineated four different types of senile plaques: diffuse non-neuritic plaques, diffuse neuritic plaques, dense-core neuritic plaques and dense-core non-neuritic plaques. The numbers of IL-1α-positive microglias and S100β-positive astrocytes associated with diffuse neuritic plaques were (7.29 ± 3.04) per mm(2) and (6.49 ± 2.20) per mm(2), respectively. In contrast, the numbers of IL-1α-positive microglias and S100β-positive astrocytes associated with diffuse non-neuritic plaques, dense-core neuritic plaques and dense-core non-neuritic plaques were (3.24 ± 1.53) per mm(2) and (4.14 ± 1.77) per mm(2), (2.09 ± 1.37) per mm(2) and (2.25 ± 0.83) per mm(2), and (1.38 ± 0.90) per mm(2) and (0.58 ± 0.36) per mm(2), respectively. The numbers of IL-1α-positive microglias and S100β-positive astrocytes associated with diffuse neuritic plaques were significantly higher than those of the other three types of plaques (P < 0.05).
CONCLUSIONThe IL-1α-positive microglias and S100β-positive astrocytes may be of certain significance in transformation of diffuse non-neuritic plaques to diffuse neuritic plaques in Alzheimer's disease.

OBJECTIVETo evaluate the clinical value of radial endorectal ultrasound (ERUS) in the assessment of preoperative staging of rectal carcinoma.
METHODSOne hundred and ten patients with rectal cancer underwent preoperative endorectal ultrasound (ERUS) examination in our hospital from February 2010 to September 2011. ERUS was performed using a Hitachi 900, Hitachi HI Vision Preirus US scanner, with a 5 - 10 MHz rigid rotating radial transducer and a focal length of 2 - 5 cm. The size, shape, echo pattern, infiltration depth, degree of circumferential involvement, extra-rectal invasion of the lesions and lymph node involvement were observed. The results of ERUS staging were compared with histopathological findings of the surgical specimens.
RESULTSThe accuracy of ERUS for T staging was 91.4%. The accuracy of ERUS in diagnosing stage T1, T2, T3, T4 cancers was 92.7%, 88.2%, 88.2% and 96.4%, respectively. The sensitivity of ERUS in diagnosing stage T1, T2, T3, T4 cancers was 92.3%, 72.7%, 85.4% and 71.4%, respectively. The specificity of ERUS in diagnosing stage T1, T2, T3, T4 cancer was 92.9%, 92.0%, 90.3% and 100.0%, respectively. Comparing the consistency of preoperative T-staging and postoperative pathological results, the Kappa value was 0.75, with a considerable consistency. The sensitivity, specificity, and accuracy of ERUS in the assessment of lymph node metastasis were 74.2%, 89.9% and 85.5%, respectively. Comparing the consistency of preoperative N-staging and postoperative pathological results, the Kappa value was 0.64, with a considerable consistency.
CONCLUSIONSERUS is a practical and accurate tool in assessment of preoperative staging of rectal tumors in regard to tumor invasion depth (T) and regional lymph node status (N), with advantages of simple operation, less pain, and high accuracy.

OBJECTIVETo evaluate prognostic factors in patients with stage IB-IIA of cervical carcinoma treated by surgery.
METHODSBetween December 1992 and December 2001, 111 patients with stage IB-IIA cervical cancer surgically treated were analyzed. Median age 40 years. According to 1994 FIGO Staging System: IB 80 (IB1 40, IB2 40) and IIA 31. There were 93 cases of squamous cell carcinoma (83.5%), 17 cases of adenocarcinoma (15.3%) and one case of small cell carcinoma. All patients were treated by radical hysterectomy and pelvic lymphadenectomy, 74 patients had preoperative adjuvant radiotherapy, 24 patients had postoperative adjuvant treatment. Kaplan-Meier method was used to evaluate the survival, the related prognostic factors were assessed by Cox regression and chi(2) test.
RESULTSThe overall 5-year survival rate was 85.9%, being 89.1%, 90.7% and 78.4% for stage IB1, IB2 and IIA, respectively. Univariate analysis showed that tumor size (hazards ratio [HR] = 1.479, P = 0.152), tumor type (HR = 1.440, P = 0.264), clinical stage (HR = 1.380, P = 0.354), adjuvant treatment (HR = 1.210, P = 0.450), lymph node metastasis (HR = 1.432, P = 0.540), endocervical involvement (HR = 2.244, P = 0.036), depth of myometrial invasion (HR = 3.295, P = 0.06) and multiple sexual partners during pregnancy (HR = 10.172, P = 0.000) were of prognostic significance. The latter two were the most important factors indicative of poor prognosis.
CONCLUSIONThe depth of myometrial invasion and multi-partners combined with pregnancy are closely related to the prognosis while the pre- and/or postoperative adjuvant therapy should be considered for stage IB-IIA cervical cancer with deep myometrial invasion and in pregnant patients with multiple sexual partners.
