OBJECTIVETo study the correlation between noise and blood pressure and/or hypertension, and its age characteristic.

METHODSThe pure tone audiometric and blood pressure examinations were performed in 14537 workers from 157 factories. Hearing impairment was used as a surrogate indicator of cumulated noise exposure. The associations of hearing impairment and duration of noise exposure with blood pressure and hypertension were analyzed respectively after age and gender stratification.

RESULTSMost of the objects were males (81.2%), younger than 35 years old (77.8%), and the duration of exposure to noise was less than 5 years (73.6%). The prevalence of hearing impairment in males was significantly higher than that in males, and increased with age and duration of noise exposure. Only in males with age younger than 35 years old, the systolic and diastolic blood pressures of subjects with sensorineural hearing loss significantly enhanced, and the diastolic blood pressure and prevalence of hypertension increased with duration of noise exposure. The risk of hypertension in males with sensorineural hearing loss significantly increased, the odds ratios in subjects with age younger than 35 years old and with age older than 35 years old were 3.0 (95%CI: 1.5 ∼ 6.1) and 2.1 (95%CI: 1.2 ∼ 3.4), respectively.

CONCLUSIONThe severe hearing impairment induced by noise was associated with hypertension. It is suggested that people should pay attention to the effects of noise on hypertension in young workers.

OBJECTIVETo investigate the effect of early intervention by pravastatin with two different dosage on inflammatory factors and endothelial vasodilator function in patients with unstable angina (UA).

METHODS108 patients with UA were investigated consecutively and divided randomly into three groups (group 20 mg, n = 37; group 10 mg, n = 37; group control, n = 34). Blood samples were examined at admission and 4, 8 weeks after the therapy of pravastatin. Fourty patients of UA were chosen from those three groups (15, 15 and 10 cases respectively). The endothelium-dependent vasodilation and the function of vascular endothelium of them were measured. In the dosage of 20 mg pravastatin group non-endothelium-dependent vasodilation in brachial artery was also tested by ultrasound before and 8 weeks after the therapy. Cardiac events were followed up for 2 months.

RESULTS(1) The use of pravastatin in early admission period of UA could significantly reduce inflammatory factors and improve vascular endothelium function, which was more obviously in the group of 20 mg/d than in group of 10 mg/d. These benefits occurred in 4th week and more obviously in 8th week after the therapy. (2) The lipid lowering therapy in the early stage of admission (24 - 48 h) resulted in the reduction of cardiac events in the hospital.

CONCLUSIONThe use of pravastatin 20 mg/d seems better than that of 10 mg/d in all the fields as above in early admission period of UA patients.

OBJECTIVETo investigate the role and significance of Wnt/beta-catenin signaling pathway regulating GSK-3beta, STAT3, Smad3 and TERT in hepatocellular carcinoma (HCC).

METHODSThe HCC cell line HepG2 was transfected with small interfering RNA (siRNA) directed against beta-catenin. Proteins were extracted and the expressions of beta-catenin, GSK-3beta, p-GSK-3beta, STAT3, Smad3 and TERT were detected by Western blot at 72 h and 96 h respectively after transfection.

RESULTSbeta-catenin expression was inhibited at both time points and the expression at 96 h was higher than that at 72 h (t = 4.43, P < 0.05). Interestingly, GSK-3beta and p-GSK-3beta expressions increased gradually at 72 and 96 h (tGSK-3beta= 4.98, tp-GSK-3beta= 29.83, P < 0.05) respectively, and STAT3 expression showed no alteration after transfection (F = 0.49, P > 0.05). Smad3 expression was increased at 72 h (t = 10.67, P < 0.05) and decreased to normal at 96 h (t = 1.26, P < 0.05), while TERT expression decreased at 72 h (t = 4.18, P is less than 0.05) and increased to normal at 96 h (t = 1.26, P > 0.05).

CONCLUSIONSWnt/beta-catenin signaling pathway is related to the expressions of GSK-3beta, Smad3 and TERT, but perhaps not related to STAT3 protein expression in HCC. It suggested that Wnt/beta-catenin signaling pathway might participate in HCC genesis and development through regulating the above three factors.

BACKGROUND: Proximal femoral nail anti-rotation is widely used to treat various intertrochanteric fractures. Although its operation trauma is small, and the blood loss of perioperative period is still large. Tranexamic acid has been gradually used to reduce the bleeding of intertrochanteric fracture. The effectiveness and safety of reducing blood loss during perioperative period were not reported. OBJECTIVE: To explore the safety and efficacy of tranexamic acid on perioperative blood loss in patients with intertrochanteric fracture undergoing proximal femoral nail anti-rotation. METHODS: One hundred and eight patients with intertrochanteric fracture undergoing proximal femoral nail anti-rotation were selected from First Affiliated Hospital, Guangzhou University of Chinese Medicine between January 2015 and January 2017. Among all the subjects, 52 patients who received the operation before January 2016 served as the control group and 56 patients who received the operation after January 2016 were selected as the treatment group. Half an hour before operation, patients in the treatment group received 1 g tranexamic acid dissolved in 250 mL normal saline by intravenous dropping; patients in the control group just received 250 mL normal saline by intravenous dropping. The bleeding volume, blood transfusion volume, hemoglobin, hematocrit, coagulation index, D-dimer levels and complications were compared between the two groups. RESULTS AND CONCLUSION: (1) During perioperative period, actual blood loss, intraoperative blood loss, dominant blood loss, recessive blood loss, volume of drainage, blood transfusion volume and blood transfusion rate were lower in the treatment group than in the control group (P < 0.05). (2) There was no statistically significant difference in the hemoglobin and hematocrit between the two groups before operation (P > 0.05). The hemoglobin and hematocrit of the two groups gradually decreased after the operation, and there was a slight improvement in the fifth day after surgery. At postoperative 2 hours, 1, 3 and 5 days, the hemoglobin and hematocrit of the treatment group were higher than in the control group (P < 0.05). At preoperation and each time point postoperation, prothrombin time, activated partial thromboplastin time, and fibrinogen levels were not statistically significant between the two groups (P > 0.05). Postoperative D-dimer levels in the two groups were significantly higher than preoperation, and there was a return on the fifth day. There was no statistically significant difference between groups at preoperation and each time point of postoperation (P > 0.05). (3) The results suggest that the tranexamic acid can effectively reduce the dominant and recessive blood loss in patients with the intertrochanteric fracture, and it is safe and effective.

The aim of this study was to establish an efficient method for expansion in vitro of natural killer (NK) cells highly purified from human peripheral blood. The CD3-CD56+CD16+ NK cells purified by the negative sorting method of MACS (magnetic microbeads activated cells sorting) were expanded with the different combinations of IL-2, SCF, IL-15 in SCGM (stem cell growth medium) supplemented with 10% human AB serum for 18 days. Cultures were fed with fresh medium and cytokines every 3 days. The sum of cells was counted for evaluating the efficiency of expansion. Then the purity of the CD3-CD56+CD16+ NK cells were determined by flow cytometry and the cytotoxicity to K562 targets was detected by CCK-8 assay in the end. Furthermore, the same way was used to explore the relationship between the efficiency of expansion, cytotoxicity to K562 targets of NK cells and the dose of IL-2. The results showed that after peripheral blood mononuclear cells (PBMNC) were purified by the negative sorting method of MACS, the purity of CD3-CD56+CD16+ NK cells increased from (12.70±2.66)% to (93.03±1.72)%. The CD3-CD56+CD16+ NK cells purified by MACS were expanded with the different combinations of IL-2, SCF, IL-15 in SCGM supplemented with 10% human AB serum for 18 days. The expanding multiple of IL-2/IL-15/SCF group was significantly higher than other groups (p<0.05). The purity of NK cells in the groups with cytokines was not significantly lower than that before expansion (p>0.05). The cytotoxicity of the groups with cytokines was significantly higher than that before expansion. Especially, the cytotoxicity (%) of NK cells in IL-2/IL-15 group and IL-2/IL-15/SCF group was more than 90%. The expanding multiples of low-dose group, medium-dose group and high-dose group were significantly higher than that of zero-dose group (p<0.05), but no significant difference was found between themselves (p>0.05). The cytotoxicity of the groups with IL-2 was significantly higher than that before expansion. Cytotoxicity to K562 cells in high-dose group was significantly higher than that in others (p<0.05); there was no significant difference between low-dose group and medium-dose group (p>0.05). It is concluded that cytokines in the 4 groups were efficient for expansion and the cytotoxicity of highly purified NK cells in vitro. IL-2/SCF/IL-15 combination is the most efficient one among different combinations, and enhanced significantly the cytotoxicity of NK cells against K562 targets. The efficiency of expansion and the cytotoxicity in vitro of NK cells are not related with the dose of IL-2, when IL-2<1,000 U/ml. It is indicated that IL-2 of high-dose (≥1,000 U/ml) may enhance the cytotoxicity of NK cells in vitro more efficiently.
