Correlation between different Chinese medicine syndromes and changes in microcirculation in septic shock patients / 中国结合医学杂志

<p><b>OBJECTIVE</b>To investigate the correlation between different Chinese medicine (CM) syndromes and variations in microcirculation in septic shock patients.</p><p><b>METHODS</b>seventy Septic shock patients were divided into four groups: heat damaging qi-yin group (HDQY, 23 cases); yin exhaustion and yang collapse group (YEYC, 26 cases); excessive heat in Fu organ group (EHFO, 10 cases); and heat damaging nutrient-blood group (HDNB, 11 cases). Sublingual microcirculation parameters were observed by sidestream dark-field (SDF) imaging and scored by Acute Physiology and Chronic Health Evaluation II (APACHE II) and the Sequential Organ Failure Assessment (SOFA), and parameters of microcirculation perfusion variations and prognoses were analyzed.</p><p><b>RESULTS</b>Compared with those with qi-yin heat damage, perfused vessel density (PVD) in other groups decreased dramatically (P<0.05), and APACHE II scores increased significantly (P<0.05). In addition, the recovery time was prolonged substantially (P<0.05), and the mixed venous oxygen saturation (SVO2) decreased (P<0.05). Blood lactic acid increased significantly (P<0.05), and the mixed SVO decreased (P<0.05), in the YEYC group. Compared with the thermal injury camp blood group, sublingual microcirculation parameter variations showed no obvious difference in the YEYC and EHFO groups (P>0.05). There were significant positive correlations between CM syndromes and APACHE II scoring in different groups (r=0.512, P<0.05). There were negative correlations between PVD and APACHE II scoring (r=-0.378, P=0.043), the proportion of perfused vessels (PPV) and APACHE II scoring (r=-0.472, P=0.008), as well as between the microvascular flow index (MFI) and APACHE II scoring (r=-0.424, P=0.023) in different patients.</p><p><b>CONCLUSION</b>Sublingual microcirculation may serve as a clinical diagnostic parameter of the patient condition, as well as being a prognostic indicator.</p>

Relationship between intrauterine infection and the gene polymorphism of DC-SIGN/DC-SIGNR in the pregnant women of HBV positive / 中华实验和临床病毒学杂志

<p><b>OBJECTIVE</b>To investigate the influence of the individual genotype differences of DC-SIGN and DC-SIGNR on the mother-to-neonate intrauterine infection of HBV.</p><p><b>METHODS</b>The genotypes of the gene DC-SIGN and DC-SIGNR in the pregnant women with HBV positive were detected by PCR and agarose gel electrophoresis. The significant difference of gene diversity of DC-SIGN and DC-SIGNR was analyzed by chi-square test.</p><p><b>RESULTS</b>(1) All of 29 cases in intrauterine infection group were 7/7 DC-SIGN genotype. In the non-intrauterine infection group, 7/5 genotype were observed in 2 of 54 cases, and the other 52 cases were 7/7 genotype. The two groups was no significant difference (P = 0.54). (2) 29 cases of intrauterine infection group was observed 4 genotypes of DC-SIGNR such as 7/7, 7/5, 9/7 and 6/5, the genotype frequencies were 0.3793, 0.3448, 0.2414 and 0.0345 respectively. 54 cases of non-intrauterine infection group was found 6 genotypes such as 7/7, 7/5, 9/5, 9/7, 7/6 and 6/5, genotype frequencies were 0.5186, 0.1481, 0.0926, 0.1852, 0.0370 and 0.0185 respectively. The distribution of 7/5 genotype in the intrauterine infection group (29 cases) and the non-intrauterine infection group (54 cases) was statistically significant (P = 0.038) , and no significant difference was found in other genotypes between the two groups (P > 0.05).</p><p><b>CONCLUSION</b>The gene DC-SIGN showed relatively little variation in the pregnant women infected with HBV. On the countrary, there were multiple genotypes of the gene DC-SIGNR in these women, and the genotype "7/5" of DC-SIGNR might be one of the susceptibility genes associated with intrauterine infection.</p>

Superselective renal artery embolization for traumatic renal hemorrhage: report of 38 cases / 介入放射学杂志

Objective To evaluate the clinical application of superselective renal artery embolization for the treatment of traumatic renal hemorrhage. Methods Thirty eight patients with traumatic renal hemorrhage were first demonstrated by renal arterigraphy under seldinger technique to ensure the rupture site and degree of renal artery and then followed by percutaneous cathetherized superselective renal arterial embolization through guidance of super slippery guide wire with gelfoam particles or steel coil. Results All 38 patients revealed occlusive abruption of bleeding arteries and disappearance of vextravasation staining after the superselective catheterized renal arterial embolization with gelfoam particles and steel spring coil under DSA. Clinically, all patients urine turned clear without macroscopic hematuria during 1 - 3 days after the procedure. Conclusions Superseclective renal arterial embolization is less aggressive and simultaneously with less complications, good hemostatic efficacy, maximal preservation of renal tissue and function for renal traumatic hemorrhage, which is worthy to be recommended.
