Acetabular fracture is an intra-articular fracture, and its treatment principle is also equivalent to that of intra-articular fracture, namely anatomical reduction of articular surface and firm fixation. Therefore, the choice of surgical approach is of great importance to the surgical exposure, reduction quality and fixation effect of acetabular fracture, which directly affects the surgical curative effect. Proper surgical approach is not only good for clear surgical exposure, easy operation, and ideal reduction quality and fixation effect, but also has great advantages in shortening the operation time, reducing intraoperative bleeding, reducing surgical trauma and avoiding surgical complications. The selection of surgical approach for acetabular fractures is closely related to the fracture injury mechanism, fracture classification, and clinical manifestations, etc.. The surgical efficacy depends on the fracture reduction quality, fixation effect, and surgical trauma degree, etc., which are closely related to the selection of surgical approach. At present, the alternative surgical approaches are generally divided into anterior approach and posterior approach. However, due to the complexity of acetabular fractures, no single surgical approach can fit all acetabular fractures, and each approach has its own indications, advantages and disadvantages.

BACKGROUND: It has become a hot issue to treat malignant tumors with retroviral mediated cytokines. But it remains a controversy whether retroviral mediated γ-interferon(IFN-γ) is valid in killing glioma cells and prolonging the survival of tumor carriers.OBJECTIVE: To observe the effect of retrovital mediated γ-interferon on the growth of glioma and the survival of tumor-carrying rats.DESIGN: Completely ramdomized trial based on animals.SETTING: Neurosurgery department of a hospital affiliated to a university.MATERIALS: The trial was conducted in the Neurosurgery Institute of Harbin Medical Unicersity from July 2002 to July 2004. The subjects were 60 male Wistar rats provided by the Animal Center of the First Affiliated Hospital of Harbin Medical Unicersity. They were randomly assigned into 3groups: C6 control group, C6/PA317neo control group and C6/PA317IFN-γ treatment group, 20 in each group.INTERVENTIONS: Retroviral vector containing murine IFN-γ gene was transferred into retroviral package cell PA317. A high titer PA317IFN-γ cell line was obtained after G418 resistance screening. In the right basal ganglion area 1 × 106 C6 cells was injected in each of the rats. The rats in C6groups received no more intervention. Those in C6/PA317neo control group received injection of 1 × 106 PA317IFN-γ cells in the right basal ganglion 4days after C6 injection. Those in C6/PA317IFN-γ treatment group received injection of 1 × 106 PA317IFN-γ cells in the right basal ganglion 4 days after selected from each group to be kill, and the brains were taken out to make frozen sections for SABC immunohistochemical staining. The CD4 and CD8 T was measured with imaging processing software under microscope.RESULTS: The mean survival time of rats in C6 and C6/PA317neo control groups was(27.10 ± 0.82) days and (26.60 ± 0.93) days respectively( P > 0.05), while that in treatment group was(49.30 ± 4. 17) days and there were five rats outlived beyond 60 days( P < 0.01 vs the two controls). The tumor volume in the two control groups was of no difference but the tumor volume in treatment was significantly smaller than that in control groups( P < 0. 01 ) . The CD4 and CD8 lymphocytes infiltration in treatment group was more than that in control groups( P < 0.01) and there was no difference between the two controls( P > 0.05) . It was also revealed through immunohistochemical examination that in treatment group there was Brdu positive cells on the 7th day and they disappeared on the 16th day. But there was no Brdu positive cells in the control groups.CONCLUSION: Intratumor injection of PA317IFN-γ induces anti-tumor immunal reaction in rats. Retroviral mediated IFN-γ inhibits tumor growth and prolongs rat survival.

Objective:Glucose-insulin-potassium(GIK) is clinically used for reducing mortality in acute myocardial infarction(MI). It is known that ventricular arrhythmia, left ventricular dysfunction and impaired baroreflex sensitivity(BRS) are the three major determinants for predicting the mortality after acute MI. The present work was designed to study the effects of GIK on BRS, ventricular arrhythmia, and left ventricular function in rats with coronary artery ligature. Sprague-Dawley rats were used and the myocardial infarction was produced by ligature of the left anterior descending artery. Five weeks after coronary artery ligation, BRS was measured in conscious state with a computerized blood pressure monitoring system and left ventricular function and electrocardiogram were determined in the anaesthetized state in the subacute phase of myocardial infarction. It was found that GIK did not affect the blood pressure and heart period in both conscious and anaesthetized rats. GIK did not enhance BRS, but reduced ventricular arrhythmia and improved left ventricular function by reducing left ventricular end diastolic pressure in anaesthetized rats with MI. It is proposed that reducing ventricular arrhythmia and improving left ventricular function contribute to the effect of GIK on reducing the mortality after MI.

Abstract: Objective To analyze and compare the differences in serum lipid metabolomics between patients with moderate to severe acne and healthy controls to understand the characteristics of serum lipid metabolism in acne patients. Methods Serum samples were collected from 30 patients with moderate to severe acne and 30 healthy controls matched for age, gender and body mass index in the Department of Dermatology, the Affiliated Hospital of Southwest Medical University
from May 2019 to Apr. 2020. Serum lipid metabolomics was analyzed by liquid chromatography-tandem mass spectrometry. Partial least squares discriminant analysis (PLS-DA) was used for multivariate statistical analysis of differentially expressed lipid metabolites. The metabolic pathways with significant differences between the two groups were screened by Kyoto Encyclopedia of Genes and Genomes (KEGG) database. Using Mann-Whitney U test to calculate differential metabolites. Spearman correlation analysis was used to analyze the correlation between serum PC (18: 2e/20: 2) concentration and acne severity. Results The PLS-DA results showed that the composition of serum lipid metabolites in acne patients was significantly separated from that in healthy controls. Of the top 30 lipid metabolites with the most significant differences, four kinds of triglycerides (TG), two kinds of diglycerides (DG), six kinds of phosphatidylcholine (PC), one kind of MePC, two kinds of sphingomyelin (SM), two kinds of phosphatidylinositol (PI), two kinds of ceramide (monohexosyl ceramide, Hex1Cer;dihexosyl ceramide, Hex2Cer), two cardiolipin (CL) were found to be increased in the acne group (P<0.05). The levels of one kind of DG, two kinds of lysophosphatidyl ethanolamines (LPE), one kind of dimethylphosphatidyl ethanolamine (dMePE), one kind of bismethyl phosphatidic acid (BisMePA), three kinds of phosphatidyl ethanolamine (PE) and one kind of ceramide were found to be decreased in the acne group (P<0.05), and most of them belonged to phospholipid metabolites. Spearman correlation analysis showed that serum PC (18:2e/20:2) concentration was positively correlated with acne severity (r=0.456, P=0.004). KEGG enrichment function analysis revealed that the differential lipid metabolites were primarily enriched in metabolic pathways such as sphingolipid signaling pathway, cholesterol metabolism, insulin resistance, glycerophospholipid metabolism, among which the sphingolipid signaling pathway may play an important role. Conclusion There are significant differences in serum lipid metabolism between acne patients and healthy controls. Lipid metabolism disorders may be related to the pathogenesis of acne, but it’s molecular mechanism still needs further experimental exploration.

Objective:Clonidine,by activating peripheral α-sbrenoceptors, produces transient pressor response after i.v.injection in anesthetized animals.Moxonidine, with at least 40-fold higher affinity to I1-imidazoline receptors than to α2-adrenoceptors,produces also a transient pressor response. This work was designed to investigate whether I1-imidazoline receptors are involved in this pressor effect of moxonidine. Methods:Female spontaneously hypertensive rats(SHRs,aged 14-16 weeks)were anesthetized with urethane.To observe the transient pressor responses,moxonidine 0.1,0.3,1.0mg/kg(intravenous,i.v),2.0μg(intracerebroventricular,i.c.v.)and 1.0,10.0mg/kg(intragastric,i.g.)were administrated in different groups of rats.To evaluate the roles of α1-adrenoceptors,α2-adrenoceptors and I1-imidazoline receptors in the transient pressor responses to moxonidine, prazosin(10.0μg/kg),yohimbine(2.0mg/kg),phentolamine(0.2mg/kg),idazoxan(1.0mg/kg)or yohimbine+idazoxan(2.0mg/kg+1.0mg/kg)were intravenously given to the animals before moxonidine 0.3mg/kg (i.v.).Results:It was found that i.v.moxonidine produced a greater pressor response than clonidine when producing a similar reduction of blood pressure.This effect of moxonidine was not influenced by prazosin, but was partly inhibited by yohimbine, phentolamine or idazoxan,and completely blocked by the combination of yohimbine and idzaxon.Neither i.c.v.injection nor i.g. administration of moxonidine induced transient pressor responses.Conclusion:The transient pressor response of i.v. moxonidine is mediated by both peripheral I1-imidazoline receptors and α2-adrenoceptors.
