OBJECTIVETo explore the intervention of Huayu Qutan Recipe (HQR) on liver SREBP-2 signal pathway of hyperlipidemia rats of Pi deficiency syndrome (PDS).

METHODSTotally 100 SPF grade SD rats were randomly divided into the blank control group, the hyperlipidemia group, the hyperlipidemia treatment group, the PDS hyperlipidemia group, and the PDS hyperlipidemia treatment group, 20 in each group. Common granular forage was fed to rats in the blank control group. High fat forage was fed to rats in the hyperlipidemia group and the hyperlipidemia treatment group. Rats in the PDS hyperlipidemia group and the PDS hyperlipidemia treatment group were treated with excessive labor and improper diet for modeling. They were administered refined lard by gastrogavage (3 mL each time, twice per day) and fed with high fat forage on the odd days, and fed with wild cabbage freely on even days. The modeling lasted for 30 days. Rats in the hyperlipidemia treatment group and PDS hyperlipidemia treatment group were administered with Huayu Qutan Recipe (20 mL/kg) by gastrogavage, once a day, for 30 successive days. Levels of serum cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), and serum amylase (AMY) were detected by automatic biochemical analyzer. D-xylose excretion rate was determined using phloroglucinol method. Morphological changes of liver and the lipid deposition in liver were observed using HE stain and oil red O stain respectively, mRNA and protein expression levels of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR), cholesterol 7α-hydroxylase 1 (CYP7A1), LDL-R, and sterol regulatory element binding protein-2 (SREBP-2) were detected using real time RT-PCR and Western blotting.

RESULTSCompared with the blank control group, serum levels of TC (1.84 ± 0.19 mmol/L, 2.23 ± 0.43 mmol/L) and LDL-C (0.99 ± 0.24 mmol/L, 1.13 ± 0.56 mmol/L) were higher in the hyperlipidemia group and the PDS hyperlipidemia group, serum levels of HDL-C (0.41 ± 0.66 mmol/L, 0.41 ± 0.11 mmol/L) and AMY activities (351 ± 45 mmol/L, 153 ± 30 mmol/L) were lower, and urinary D-xylose excretion rates were lower (26.9 ± 2.1 ng/mL, 15.0 ± 1.7 ng/mL) (all P < 0.05). Lipid deposition occurred in liver cells. Much fat vacuoles occurred in the cytoplasm. Expression levels of HMGCR, CYP7A1, LDL-R, and SREBP-2 mRNA and proteins in liver significantly decreased (P < 0.01). Compared with the hyperlipidemia group, serum levels of TC and LDL-C significantly increased (P < 0. 05), AMY activities and urinary D-xylose excre- tion rates significantly decreased in the PDS hyperlipidemia group (P < 0.01). A large amount of lipid deposition occurred in liver. The atrophy of liver cells was obviously seen. Expression levels of CYP7A1, LDL-R, and SREBP-2 mRNA and proteins in liver were significantly lower (P < 0.01, P < 0.05). Serum levels of TC and LDL-C significantly decreased (P < 0.05), AMY activities and urinary D-xylose excretion rates significantly increased in the hyperlipidemia treatment group (P < 0.01). Expression levels of CYP7A1, LDL-R, and SREBP-2 mRNA and proteins in liver were significantly increased (P < 0.01, P < 0.05). Compared with the PDS hyperlipidemia group, serum level of TC significantly decreased (P < 0.05), HDL-C levels, AMY activities and urinary D-xylose excretion rates significantly increased in the PDS hyperlipidemia treatment group (P < 0.01),expression levels of CYP7A1, LDL-R, and SREBP-2 mRNA and proteins in liver were significantly increased (P < 0.01). Similar changes occurred in the two treatment groups.

CONCLUSIONSPi deficiency exacerbates abnormal serum TC level and the lipid deposition in liver. These might be related to regulating expression levels of LDL-R, HMGCR, and CYP7A1 genes in the SREBP-2 signal pathway. HQR could regulate this pathway to intervene abnormal metabolism of TC.

OBJECTIVETo investigate the DNA and chromosome damage in peripheral blood lymphocyte of workers occupationally exposed to formaldehyde (FA).

METHODSAll 151 workers occupationally exposed to FA from two plywood factories and 112 workers without occupational FA exposure working in a machine manufactory were recruited into this study. Comet assay and cytokinesis-block micronucleus technique was used to evaluate the DNA and chromosomal damage of peripheral blood lymphocyte. The air FA samples were collected with SKC 224-PCXR8 air samplers. Gas chromatography was used to analyze the FA level. Personal information including occupational history, age, sex, smoking and drinking status was collected by the questionnaire.

RESULTSThe time weighted average concentration (TWA) of FA in the working environment of FA-exposed workers (range 0.10 - 7.88 mg/m(3)) was higher than those in controls (< 0.01 mg/m(3)). The olive tail moment (Olive TM) in low FA-exposed workers [3.03 (2.49 - 3.67)] was lower than that in high FA-exposed workers [3.95 (3.53 - 4.43)], but higher than that in controls [0.93 (0.78 - 1.10)], the differences were statistical significant (P < 0.05). Comet trail length in FA-exposed workers were significantly higher than that in controls [6.78 (6.05 - 7.60)], but no significant differences ware found between the high FA-exposed workers [12.59 (11.80 - 13.43)] and the low FA-exposed workers [11.25 (10.12 - 12.50)]. The frequency of micronuclei per 100 binucleated cells in low FA-exposed workers (0.41 +/- 0.25) was lower than that in high FA-exposed workers (0.65 +/- 0.36), but higher than that in controls (0.27 +/- 0.13), the differences were statistical significant (P < 0.05). The increased tendencies with the exposure levels were found in those three indices. In stratification analysis, the same results were found.

CONCLUSIONIn the current FA exposure levels, the DNA and chromosomal damage in peripheral blood lymphocyte might be induced by FA exposure, and be increased with the levels of exposure.

Objective: To observe the bone marrow signals of acetabulum and proximal femur of asymptomatic non-professional marathoners by 3.0 T magnetic resonance imaging (MRI) T₁WI, and evaluate the bone marrow transformation, so as to obtain the effect of Marathon exercise on bone marrow composition and function. Methods: The study group was randomly selected to participate in and complete the whole marathon at least once a year in the past two years. The training mileage of long-distance running was not less than 1 600 kilometers per year. There were no symptoms such as hip pain. There were no abnormalities in hip joint physical examination. The age of 22-53 years old. A total of 31 and 62 hips were evaluated. The control group was randomly selected 29 healthy persons (58 hip joints), aged 23-53 years, without hip pain and regular exercise. All subjects underwent hip joint MRI scan, and the hip joint MRI showed normal. At least 12 hours before MR scan, he did not engage in long-distance running or other sports. The bone marrow signal intensity of acetabulum and proximal femur in T₁WI was compared with that of surrounding muscles and fat. The signal intensity was graded from low to high and evaluated by grade. The research group was divided into two groups according to the training years of marathon (running age). The running age of group A was more than 4 years and group B was less than 4 years. The distribution of bone marrow signal in proximal femur was also evaluated by a more intuitive 3-4 classification method. Mann-Whitney U test was used for statistical analysis. Results: Bone marrow signal grading evaluation showed that there were significant differences in bone marrow signal grade distribution between the two groups (Z=-6.828, -4.779, -3.046, -5.266, -3.490, - 5.053, P<0.05). In the study group, there were 14, 28 hips and 168 parts in group A, 17, 34 hips and 204 parts in group B, bone marrow signals were graded. There were significant differences in acetabulum, femoral neck and upper femoral shaft bone (Z=-2.202, -2.214, -2.730, P<0.05), but no significant differences in femoral head, trochanter and trochanter bone (Z=-0.886, -1.642, -0.711, P>0.05). To evaluate the classification of bone marrow signals in proximal femur, 62 cases of bone marrow signals in the study group were classified as follows: 10 cases with type 1a, 24 cases with type 1b, 17 cases with type 2 and 11 cases with type 3. In the control group, 58 cases of bone marrow signals in proximal femur were classified as follows: 2 cases with type 1a, 13 cases with type 1b, 26 cases with type 2 and 17 cases with type 3. There were significant differences between the two groups (Z=-4.003, P<0.05). Conclusion The T₁WI signal intensity of asymptomatic non-professional marathoners′ acetabulum and proximal femur bone marrow is lower than that of non-marathoners; the T₁WI signal intensity of acetabulum, femoral neck and upper femoral shaft bone marrow of the elderly runners is lower; that is, marathon exercise has certain influence on the bone marrow signal of acetabulum and proximal femur, that is, the change of bone marrow signal in weight-bearing area has a certain phase with the amount of exercise.

OBJECTIVETo investigate the clinicopathological characteristics of primary Burkitt's lymphoma (BL) in the spermatic cord.

METHODSA case of BL of the spermatic cord was studied by histopathology and immunohistochemical techniques. The clinical data and the related literature were reviewed.

RESULTSThe patient was a 4-year-old boy, who was accidentally found with a bump in the scrotum. Surgery showed it to be a tumor located in the left spermatic cord and 5 cm x 3 cm x 2 cm in size, gray and fish-like on cross-sectional imaging. Histologically, it was characterized by monotonous infiltration of medium-sized cells with round nuclei, coarse chromatin, 2-5 basophilic nucleoli, and an appreciable rim of basophilic cytoplasm, in a typically starry-sky pattern imparted by interspersed tangible-body macrophages. Immunohistochemically, the tumor cells were diffused, positive for CD20 and CD79, some for CD10 and about 95% with the nuclear expression of Ki-67, but negative for CD3, CD43, bcl-2 and TdT as well as for EBER in situ hybridization.

CONCLUSIONPrimary spermatic cord BL is extremely rare, highly aggressive and with poor prognosis. Diagnosis of the tumor relies on its pathological characteristics and immunohistochemical staining. It is essential to differentiate BL from other types of lymphomas and malignant small-cell tumors of the non-lymphatic system.
