OBJECTIVETo evaluate the abnormal state of liver function and plasma lipid levels of obese schoolchildren who were screened by weight-for-height criterion and new body mass index criterion respectively.

METHODS280 obese children were screened by weight-for-height criterion and 125 obese children were screened by body mass index criterion in a routine school check-up program. All of the latter subjects was included in the former one. One obese child and 1 non-obese child were matched for gender and age. 14 items related to liver functions and plasma lipids were measured.

RESULTSOf the abnormal items,7 items in 125 obese children screened by new BMI criterion and 5 items in 155 "obese children" excluded by BMI criterion, were significantly higher than those children among controlled group. The abnormal rates were 10.4%-22.9% in the former and 3.2%-13.0% in the latter.

CONCLUSIONSThe new BMI criterion seemed to be more stringent than weight-for-height. Less than a half of the obese children screened by weight-for-height were taken on obese children by new BMI criterion. The overweight children who were screened by BMI criterion also had abnormal liver functions and plasma lipids.

OBJECTIVETo investigate the signal patterns of dual color dual fusion (DCDF) probe and extra signal (ES) probe in the detection of BCR/ABL fusion gene, and illustrate the relation between the fluorescence in situ hybridization (FISH) pattern and the karyotype.

METHODSSixty-five cases of chronic myelocytic leukemia (CML) and 50 cases of acute lymphoblastic leukemia (ALL) were detected by FISH with DCDF probe, the BCR/ABL positive samples were detected by FISH with ES probe. Among these cases, 47 cases of CML and 40 cases of ALL perform conventional cytogenetics simultaneously.

RESULTSAll 65 cases of CML were all BCR/ABL positive by FISH. 17 cases showed the atypical pattern by DCDF-FISH, and 12 cases showed the atypical pattern by ES-FISH. There were 7 cases of BCR/ABL positive in 50 cases of ALL by FISH. By ES-FISH, there were 5 cases in which the break-point of BCR gene was located in m-bcr, 2 cases in which the break-point of BCR gene was located in M-bcr. Conventional cytogenetics demonstrated that 43/44(98%) cases of CML and 7/32(22%) cases of ALL were Ph positive.

CONCLUSIONThe features of DCDF-FISH, ES-FISH and conventional cytogenetic are different from each other. According to the features of these method, it can increase the precision of the adjustment of genetic feature to analyze these results comprehensively.

To investigate the urination-reducing effect and mechanism of Zhuangyao Jianshen Wan (ZYJCW). In this study, SI rats were subcutaneously injected with 150 mg · kg(-1) dose of D-galactose to prepare the sub-acute aging model and randomly divided into the model group, the Suoquan Wan group (1.17 g · kg(-1) · d(-1)), and ZYJCW high, medium and low dose groups (2.39, 1.20, 0.60 g · kg(-1) · d(-1)) , with normal rats in the blank group. They were continuously administered with drugs for eight weeks. The metabolic cage method was adopted to measure the 24 h urine volume and 5 h water load urine volume in rats. The automatic biochemistry analyzer was adopted to detect urine concentrations of Na+, Cl-, K+. The ELISA method was used to determine serum aldosterone (ALD) and antidiuretic hormone (ADH). The changes in P2X1 and P2X3 mRNA expressions in bladder tissues of rats were detected by RT-PCR. According to the results, both ZYJCW high and medium dose groups showed significant down-regulations in 24 h urine volume and 5 h water load urine volume in (P <0.05, P <0.01), declines in Na+ and Cl- concentrations in urine (P <0.01), notable rises in plasma ALD and ADH contents (P <0.05, P <0.01) and remarkable down-regulations in the P2X1 and P2X3 mRNA expressions in bladder tissues (P <0.01). The ZYJCW low dose group revealed obvious reductions in Na+ and Cl- concentrations in urine (P <0.01). The results indicated that ZYJCW may show the urination-reducing effect by down-regulating the P2X1 and P2X3 mRNA expressions in bladder tissues of rats with diuresis caused by kidney deficiency.

Objective Using gradient-echo sampling of spin-echo (GESSE) sequence to study the change of oxygen extraction fraction (OEF) in patients with unilateral cerebral vessel stenosis and the relationship between OEF and cerebral blood flow (CBF). Methods Eight normal volunteers and 16 patients with unilateral cerebral vessel stenosis were enrolled in this study. Written informed consents were obtained from all subjects. Routine MRI, GESSE and arterial spin labeling (ASL) sequences were performed for all patients. Raw data from GESSE and VE-ASL sequences were transferred to PC to conduct postprocessing. To obtain quantitative OEF and CBF of the brain parenchyma, 6 ROIs were placed respectively in the anterior, middle and posterior part of both hemispheres. The relative CBF (rCBF) was defined as the ratio of CBF of ischemic hemisphere to that of contralateral hemisphere. T test was used for statistics. Results The mean value and normal range of OEF in the volunteers were 0. 318 ± 0. 023 and 0. 272-0. 364, respectively. In the 16 patients with unilateral cerebral vessel stenosis, 8 patients had ROIs with greater OEF in unilateral hemisphere than those in contralateral hemisphere. These cases presented multiple intracranial main arterial stenoses in digital subtraction angiography (DSA) or MR angiography (MRA) examination. The other 8 patients had normal OEF in all ROIs. And they only had single arterial stenosis in DSA or MRA. Set rCBF = 0. 50 as a dividing point, the mean OEF value was 0. 397 ±0. 010 in the patients with rCBF ＜ 0. 50. In the patients with rCBF ≥ 0. 5, the mean OEF value was 0. 325 ±0. 028. The difference between the two groups was statistically significant (t = - 8. 840, P = 0. 000).Conclusion Patients with chronic cerebral ischemia may present with various hemodynamic impairment.The more CBF decreases, the more OEF increases. Those with increased OEF tended to have more than one lesion in the major intracranial arteries.

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.
