OBJECTIVETo study the curative effect of postural reduction with instrumental reduction in treatment of flexion-distraction thoracolumbar fractures.

METHODSA retrospective study was performed on 43 patients with single thoracolumbar flexion-distraction fractures admitted from August 2009 to August 2011, included 28 males and 15 females with an average age of 44 years old (34 to 56 years old). All patients were treated with postural reduction with instrumental reduction. The kyphosis (Cobb angle) recovery of injured vertebral height and complication were analyzed. The visual analogue scale(VAS) and com-plications were followed up and recorded.

RESULTSThere was no difference in recovery of injured vertebral posterior height among preoperative, 1 week and 1 year after operation (P > 0.05). There were significantly difference in kyphosis (Cobb angle) and recovery of injured vertebral anterior height between preoperative and postoperative at 1 week (P < 0.05). There was no difference in kyphosis (Cobb angle) and recovery of injured vertebral anterior height between 1 week and 1 year after operation (P > 0.05). VAS significantly improved from preoperative (7.2 +/- 1.2) to (0.8 +/- 0.7) at 1 year after operation (t = 18.47, P < 0.001).

CONCLUSIONPostural reduction with instrumental reduction is effective for thoracolumbar flexion-distraction fractures and it is beneficial to the recovery of vertebral height and saggital alignment.

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.

OBJECTIVETo explore the clinical and physical factors that might give rise to radiation-induced esophagitis in three-dimensional conformal radiotherapy for non-small cell lung cancer.

METHODSTo collect the clinical and physical records and follow-up information of 106 NSCLC patients without undergoing surgery in our hospital. χ(2) test, linear tendency test and analysis of variance were employed to analyze the relationship between occurrence of radiation-induced esophagitis and clinical and physical treatment. Logistic analysis was also used for multivariate analysis.

RESULTSAmong the 47 cases of radiation-induced esophagitis, 31 cases were of grade I, 11 of grade II, 5 of grade III, and with a total occurrence rate of 44.3% (47/106). Radiation-induced esophagitis was correlated with Karnofsky scores, radiation sensitization and tumor location (χ(2) = 11.30, 8.45, 7.67, P < 0.05). Radiation-induced esophagitis was correlated with the length of irradiated esophagus and average dose of irradiated esophagus (F = 20.82, 83.08, P < 0.001). With the increase of the irradiated volume percentage from V20, V30, V40 up to V50, the occurrence rate of radiation-induced esophagitis was also increased, almost with a linear trend (P < 0.05). Application of all the above factors to logistic model indicated that radiation sensitization,length of irradiated esophagus, average dose and V50 were all statistically significant foactors in the occurrence of radiation-induced esophagitis (OR = 0.321, 2.850, 7.307 and 8.558, P < 0.05).

CONCLUSIONSRadiation sensitization,length of irradiated esophagus, average dose of irradiated esophagus and V50 are independent factors in the occurrence of radiation-induced esophagitis. V50 is of greater importance in the judgement of occurrence of radiation-induced esophagitis.

BACKGROUNDThis study was undertaken to obtain differentially expressed genes related to human glioma by cDNA microarray and the characterization of a novel full-length gene.

METHODSTotal RNA was extracted form human glioma and normal brain tissue, and mRNA was used as a probe. The results of hybridization procedure were scanned with the computer system. The gene named 507E08 cone was subsequently analyzed by northern blot, bioinformatic approach, and protein expression.

RESULTSFifteen differentially expressed genes were obtained from human glioma by hybridization and scanning for four times. Northern blot analysis confirmed that the 507E08 clone was low expressed in human brain tissue and over expressed in human glioma tissues. The analysis of BLASTn and BLASTx showed that the 507E08 clone was a novel full-length gene, which codes 203 amino acid of protein and is called human ribosomal protein 14.22 gene. The nucleotide sequence had been submitted to the GenBank with the accession number of AF329277. After expression in E. coli., protein yielded a major band of apparent molecular mass 22 kDa on an SDS-PAGE gel.

CONCLUSIONScDNA microarray technology can be successfully used to identify differentially expressed genes. The novel full-length gene of human ribosomal protein 13.22 may be correlated with the development of human glioma.

In order to compare the differences of 35 Menthae Herba samples collected on the market and at producing areas, the contents of six total terpenoids, the essential oil and chromatographic fingerprints were analyzed, which provided evidences for drawing up the commodity specifications and grading criteria of Menthae Herba. GC-MS method was used to analyze the chemical constituents of 35 different samples. The chromatographic fingerprints obtained by using GC were then evaluated by similarity analysis, hierarchical clustering analysis and principal component analysis. The relativity between the content of six terpenoids and the essential oil were studied. In this study, the chemical profiles of 35 samples from different producing areas had significant disparity. All samples collected in the report could be categorized into four chemical types, L-menthol, pulegone, carvone and L-menthone, but the chemical profiles had no relationship with the areas. The chromatographic fingerprints of the samples from different types were dissimilar, while the different producing areas were difficult to be separated. It was indicated that the content of volatile oil was positively correlated with the content of L-menthol and the sum of six total terpenoids. The content of the essential oil, L-menthol and the sum of six total terpenoids of Menthae Herba were considered as one of the commercial specifications and grading criteria. These results in the research could be helpful to draw up the commercial specification and grading criteria of Menthae Herba from a view of chemical information.

OBJECTIVETo observe the effect of Yanggan Yishui Granule (YGYSG) on collagen protein I, III, and IV, as well as fibronection (EN) in spontaneously hypertensive rats (SHR), and to explore its possible renal protective mechanisms.

METHODSFourty SHR were randomly divided into four groups, i.e., the model group, the Benazepril group, the low dose YGYSG group, and the high dose YGYSG group, 10 in each group. A normal control group was set up with recruited Wistar-Kyoto (WKY) rats. After 6 weeks of treatment, the expression of collagen protein I, III, and IV, as well as FN in the 5.1 image analysis system.

RESULTSIn the WKY-control group, there was only a small amount of brown particles in the mesenchymal region, the glomerular basement membrane, or the mesangial region. The expression of collagen I, Ill, and IV, as well as EN significantly increased more in the model group than in the normal control group (P < 0.01). After treatment, the expression of collagen I, III, and IV, as well as FN significantly decreased in each treated group, showing statistical difference when compared with the model group (P < 0.01). Besides, decresed expression of collagen I, III, and IV was shown in the low dose YGYSG group and the Benazepril group (P > 0.05). The expression of collagen I, III, and IV could be further reduced in the high dose YGYSG group, showing statistical difference when compared with the Benazepril group and the low dose YGYSG group (P < 0.05, P < 0.01).

CONCLUSIONYGYSG might play an important role in the renal protective effect through reducing the synthesis of renal collagen I, III, and IV, as well as FN, increasing the degradation of renal collagen I, III, and IV, as well as FN, thereby reducing excessive deposition of renal extracellular matrix (ECM).
