OBJECTIVETo observe the clinical significance of nitric oxide (NO) and 8-isoprostane (8-isoPG) changes in exhaled breath condensate ( EBC) of acute respiratory distress syndrome (ARDS) patients after treated by Qingfei Decoction (QD).
METHODSTotally 48 ARDS patients receiving mechanical ventilation were equally assigned to the QD treatment group and the control group by random digit table. EBC specimens were collected by modified Ecoscreen breath condensate collector (German JAEGER Company) on the first day and the fifth day after confirmed diagnosis of ARDS. Concentrations of NO and 8-isoPG in EBC were measured by ELISA. The oxygenation index and APACHE II scores were recorded at the same time.
RESULTS(1) The fatality rate in the QD treatment group was lower than that in the control group (8.3% vs 37.5%, P < 0.05). (2) After treatment NO and 8-isoPG concentrations in EBC were lower in the QD treatment group (34.49 ± 5.67 µmol/L, 30.09 ± 7.89 ng/L) than in the control group (39.78 ± 9.27 µmol/L, 35.65 ± 8.90 ng/L; P < 0.05). (3) After treatment improved oxygenation index value was higher in the QD treatment group than in the control group (120.88 ± 35.16 vs 101.50 ± 37.70, P < 0.05). After treatment APACHEII scores was lower in the QD treatment group than in the control group (6.21 ± 3.51 vs 10. 26 ± 4.33, P < 0.05).
CONCLUSIONTreatment of ARDS patients by QD was favorable in controlling inflammation, alleviating lung injury, and improving clinical efficacy.

OBJECTIVENoninvasive method for estimating the pulmonary vascular resistance (PVR) was used in patients waiting for two staged Fontan procedure to observe the relationship between estimated PVR and surgical results.
METHODSThirty-three candidate patients for two staged Fontan procedures were randomly selected for this trial. Preoperative hemoglobin (HGB), hematocrit (HCT) and pulse oxygen saturation (SpO2) were measured. Estimated PVRs were then calculated by the regression equations. The cases were divided into three groups of low risk group with PVR less than 2.4 wood, high risk group with PVR between 2.4 to 3.2 wood, and extremely high risk group with PVR more than 3.2 wood. The incidences of postoperative low cardiac output and multi-organ failure were compared. Simultaneously, the cases without or with postoperative severe low cardiac output and multi-organ failure after operation were divided into two groups. The preoperative HGB, HCT and estimated PVR among the groups were analyzed.
RESULTSThe rates of postoperative severe low cardiac output and multi-organ failure were 10.0%, 32.4% and 63.6% for the patients of low, high and extremely high risk groups respectively. The difference was significant (P < 0.01). The preoperative HGB, HCT, SpO2 and PVR were all significantly different between the patients without or with postoperative severe low cardiac output and multi-organ failure. The PVR (HGB) were (2.53 +/- 0.56) wood and (3.24 +/- 0.58) wood respectively. The PVR (HCT) were (2.59 +/- 0.58) wood and (3.21 +/- 0.79) wood respectively. The PVR (SpO2) were (2.22 +/- 0.55) wood and (2.93 +/- 0.58) wood, respectively. The differences were all significant (t = 3.25, 2.52 and 3.33 respectively, P < 0.01 or 0.05).
CONCLUSIONSPreoperative estimated PVRs calculated by HGB, HCT and SpO2 were comparable with the postoperative results. Thus, the invasive preoperative estimation of pulmonary vascular resistance could be a method in estimating the surgical indication and predicting the surgical result for two stage Fontan procedure.

The study was purposed to explore the efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) combined with Imatinib for treatment of Philadelphia chromosome positive acute lymphoblastic leukemia (Ph(+)ALL) patients. From 2007 to 2008, 3 patients with Ph(+)ALL were treated with allogeneic hematopoietic stem cell transplantation and Imatinib, and the follow-up ended at Oct 21(st) 2009. 1 patient received HSCT from matched sibling donor and 2 patients from haploidentical related donors. All 3 patients achieved complete remission before transplantation and were treated with Imatinib for distinct time at different periods before and/or after transplantation. The level of bcr/abl mRNA was monitored using real-time PCR. The results showed that all 3 patients achieved stable engraftments without severe transplantation related complications. The level of bcr/abl mRNA declined and achieved zero level finally. In conclusion, the allo-HSCT combined with Imatinib is an effective therapy regimen for Ph(+)ALL patients.

OBJECTIVETo compare the diagnostic accuracy of (99)Tc(m)-MIBI SPECT/CT and (18)F-FDG coincidence SPECT/CT for solitary pulmonary nodules.
METHODSA total of 88 cases suspected of solitary pulmonary nodules were analyzed retrospectively, of whom 36 were examined with (18)F-FDG coincidence SPECT/CT and 52 with (99)Tc(m)-MIBI SPECT/CT. The nature of the solitary pulmonary nodules (malignant or benign) were determined according to the pathological or follow-up (>2 years) results. The diagnostic accuracy of the two modalities for solitary pulmonary nodules was evaluated by ROC curve. The correlation of the lesion size and pathological grade determined by the two modalities with the L/N ratio was assessed using Spearman correlation analysis.
RESULTS(18)F-FDG coincidence SPECT/CT and (99)Tc(m)-MIBI SPECT/CT showed a similar area under curve (AUC) of the L/N ratio (0.92 vs 0.88, P=0.565) with diagnostic sensitivities of 76.92% (20/26) and 80.77% (21/26) and specificities of 100% (10/10) and 88.46% (23/26), respectively. For solitary pulmonary nodules with lesion diameter ≤2 cm, the AUC was 1.00 with (18)F-FDG coincidence SPECT/CT and 0.90 with (99)Tc(m)-MIBI SPECT/CT (P=0.746), while for nodules beyond 2 cm but below 3 cm, the AUCs were 0.79 and 0.89, respectively (P<0.001). In either of the two modalities, correlation analysis revealed no correlation of the L/N ratio with the pathological grade of the malignant lesions (P=0.771 and 0.077, respectively). The L/N ratio was not correlated with the size of the malignant lesion detected by (99)Tc(m)-MIBI SPECT/CT (P=0.516) but was significantly correlated with the size of the malignant lesions detected by (18)F-FDG coincidence SPECT/CT (P=0.016).
CONCLUSION(99)Tc(m)-MIBI SPECT/CT has a greater diagnostic accuracy than (18)F-FDG coincidence SPECT/CT for solitary pulmonary nodules with lesion a diameter beyond 2 cm, and is therefore the primary choice for low-income patients.

OBJECTIVETo evaluate the expression of interleukin-6 (IL-6) and its clinicopathological significance in Castleman's disease (CD).
METHODSClinical data and paraffin blocks of 92 CD patients and 20 cases of lymph node reactive hyperplasia (LRH) as a control group were collected from department of pathology of Peking University Health Science Center. The expression of IL-6 was detected by using immunohistochemical method.
RESULTSThe 92 patients were composed of 42 multicentric variant (MCDs) and 50 unicentric variant (UCDs) clinically, and 30 hyaline-vascular variant (HV-CDs) and 62 plasma cell variant (PC-CDs) morphologically. None of them was positive for HIV tests. There were 56 males and 36 females, and their ages ranged from 4 years to 90 years with the median 41 years. IL-6 was expressed in 77 (83.7%) of 92 CD cases and 1 (5.0%) of 20 LRH cases. The expression rate of IL-6 was 90.5% in MCDs, 78.0% in UCDs, 93.6% in PC-CDs and 63.4% in HV-CDs, respectively. PC-CD cases showed a significantly higher expression rate of IL-6 than HV-CD cases (P = 0.001). All cases with positive IL-6 expression in plasmacytes were PC-CDs, showing obviously higher expression in MCDs than that in UCDs (P = 0.003). Compared with HV-CD cases, much more PC-CD cases showed IL-6 positivity in endothelial cells (P = 0.008). However, IL-6 was rarely expressed by both FDCs and macrophages, with only 3.3% and 10.9% positive cases, respectively. There are 53.2% (41/77) of the IL-6 positive cases and 20.0% (3/15) of IL-6 negative cases suffered from systemic symptoms, showing a significant difference between the two groups (P = 0.018). Cases with IL-6 expression in plasmacytes and macrophages were more likely to suffer from systemic symptoms, especially B type symptoms (P < 0.05).
CONCLUSIONThere is a high expression rate of IL-6 in CD, which is different from LRH. The expression of IL-6 has close relationship with CD subtypes and the presence of systemic symptoms. In all, the evaluation of interleukin-6 is of great value to guide the diagnosis and therapy of CD.

OBJECTIVEShen Yan Ling Tablet is an innovative compound of traditional Chinese medicine, scientifically prepared with Tripterygium wilfordii, Radix Astragali, and others, with precise efficacy on renal diseases and reduced adverse effects of Tripterygium wilfordii. Based on the Guiding Principles for New Drug Toxicity Research Before Clinical Application, we investigated the long-term toxicity of Shen Yan Ling Tablet and its effect on the reproductive function in rats.
METHODSAccording to the clinical therapeutic dose and the results of the acute toxicity test of Shen Yan Ling Tablet, we equally divided 80 rats (males and females half-and-half) into a low-dose (1.25 g/kg body wt), a medium-dose (2.50 g/kg body wt), a high-dose (5.00 g/kg body wt) and a control group. After a 3-month medication, we conducted standardized long-term toxicity tests and observed the effects of Shen Yan Ling on the serum sexual hormones and epididymal sperm count.
RESULTSAfter 3 months of treatment with Shen Yan Ling, no death occurred, the general status remained unchanged, and the parameters of blood cytology and biochemistry fluctuated within the normal range, without any significant changes (P > 0.05). Some blood parameters, RBC, WBC, HGB, AST and TBIL, showed statistic changes (P < 0.05), but with no clinical significance. There were no significant differences in the mass coefficients of the main organs between the medication and control groups. The high-dose group exhibited slight hepatic and pulmonary pathological changes and significantly reduced sperm counts in the epididymis, but no significant changes in serum sexual hormones (P < 0.05).
CONCLUSIONThree-month medication of Shen Yan Ling at 1.25 - 5.00 g/kg produced no significant accumulated toxicity on rats, but it had a negative effect on their reproductive function at a higher dose of > or = 5.00 g/kg.

OBJECTIVETo investigate the efficacy and safety of diisopropylamine dichloroacetate in the treatment of nonalcoholic fatty liver diseases (NAFLD).
METHODSA randomized, double-blind, dose-paralleled control trial was carried out with NAFLD patients. The patients were randomly assigned to 2 groups treated with either a high dosage (120 mg/d) or a low dosage (60 mg/d) of diisopropylamine dichloroacetate for 8 weeks and the efficacy and safety of the drug were examined.
RESULTS127 cases were recruited for the trial, 63 in the high dosage group, and 64 in the low dosage group. No case dropped out in the trial but four cases were eliminated (4/127, 3.1%). The final number in this trial was 123, with 61 in the high dosage group and 62 in the low dosage group. After 8 weeks of treatment, the overall improvement of clinical symptoms in the high dosage and in the low dosage group was 87.8% and 79.6%, respectively. ALT normalization was found in 55.7% and 69.4% of the cases in the two groups, serum lipids were lowered in 67.2% and 67.7% and ultrasound grading of the liver alteration severity was lowered in 51.7% and 43.5% in the two groups. The differences found between the two groups were of no statistical significance. One case from each group was found having an adverse drug reaction of dryness of the mouth (1.6%). No severe adverse drug reactions were found.
CONCLUSIONDiisopropylamine dichloroacetate could be used as a safe and effective drug in the treatment of nonalcoholic fatty liver diseases.

OBJECTIVE:
To study the value of fast spin-echo diffusion weighted imaging (TSE-DWI) apparent diffusion coefficient (ADC) in children aged 2-12 years with intellectual disability (ID)/global developmental delay (GDD) who have normal conventional brain MRI findings.
METHODS:
A total of 578 children with normal conventional brain MRI findings who met the diagnostic criteria for ID/GDD and 375 normal children were enrolled. Their imaging and clinical data were collected. All children underwent scanning with brain TSE-DWI sequence and routine sequence. ADC values of each brain region were compared between normal children with different ages, as well as between children with different degrees of ID/GDD in each age group. The influence of Adaptive Behavior Assessment System-II (ABAS-II) score on ADC values of each brain region was analyzed.
RESULTS:
For the normal children, the ADC values of the frontal and temporal white matter, the corpus callosum, the inner capsule, the centrum semiovale, the cerebellar dentate nucleus, the optic radiation, the thalamus, the lenticular nucleus, and the caudate nucleus gradually decreased with age (P<0.05). ADC values of the deep white matter, the shallow white matter, the deep gray matter nuclei, and the shallow gray matter increased with the increase in the degree of ID/GDD in the ID/GDD children aged 4-6 years (P<0.05). In the children with ID/GDD, the ADC values of the deep white matter, the shallow white matter, and the deep gray matter nuclei decreased with age (P<0.05). The ADC values of the children with ID/GDD decreased with the increase in ABAS-II score (P<0.05).
CONCLUSIONS
ADC can reflect the subtle structural changes of brain regions in children with ID/GDD who have normal conventional brain MRI findings. It may be associated with social adaptation. It can provide an objective basis for the quantitative diagnosis of ID/GDD in children.

OBJECTIVETo explore the effects of ischemia postconditioning (IPC) on ischemia-reperfusion (I/R) injury and associated reperfusion injury salvage kinase (RISK) signal transduction pathways changes in isolated mouse hearts.
METHODSLangendorff perfused C57/BL mouse hearts were divided to 6 groups: (1) control: 30 min global ischemia and 2 h reperfusion (I/R); (2) IPC with 3 episodes, IPC with 3 episodes of 10 s of ischemia and 10 s reperfusion after 30 min ischemia and before 2 h reperfusion; (3) IPC with 6 episodes, IPC with six episodes of 10 s of ischemia and 10 s reperfusion after 30 min ischemia and before 2 h reperfusion; (4) delayed IPC, IPC with 3 episodes of 10 s of ischemia and 10 s reperfusion after 30 min ischemia and at one minute after reperfusion; (5) IPC + ERK1/2 inhibitor PD98059 (10(-5) mol/L for 15 min); (6) I/R + ERK1/2 inhibitor PD98059 (10(-5) mol/L for 15 min). The effects of IPC on hemodynamics, coronary artery flow, creatine kinase (CK) and lactate dehydrogenase (LDH) release, myocardial SOD, MDA, phospho-protein kinase (P-ERK1/2) and phospho-protein kinase B (P-Akt) as well as myocardial infarction size were measured.
RESULTSIPC with 3 episodes and IPC with 6 episodes significantly and equally improved myocardial function, increased myocardial SOD, reduced CK and LDH release and myocardial infarction size compared with IR group (all P < 0.01) while these parameters were similar between I/R hearts and delayed IPC hearts. IPC significantly increased myocardial ERK1/2 phosphorylation, PD98059 inhibited the phosphorylation of ERK1/2 and abolished the cardioprotective effects induced by IPC.
CONCLUSIONSIPC obviously attenuated I/R injury in isolated mouse hearts, the cardioprotection of IPC was not enhanced because of increasing of IPC episodes and disappeared in delayed IPC. The cardioprotective effects of IPC were mediated through ERK1/2-MAPK signal transduction pathway.
