Study of central venous oxygen saturation used in transfusion of hemorrhagic shock rabbits / 中国医师杂志

ObjectiveTo study central venous oxygen saturation (ScyO2) in controlled hemorrhagic shock rabbits resuscitation process as a transfusion trigger and traditional transfusion trigger of comparison.MethodsSelection New Zealand pure line of rabbit 32 only,simple randonly divided into 4 groups,groups A and B for the observation group,groups C and D as control group,groups of eight only.A,B,C,D four groups respectively by ScvO2 ≤70％,ScvO2 ≤75％,hemoglobin (Hb)≥8g/dl,blood loss for the whole blood volume≥30％ as transfusion trigger.From right femoral artery bloodletting 10 minute inside,made the MAP to about (40 ± 5 )mmHg,and maintained the blood pressure 60 minutes,established controlled hemorrhagic shock rabbits of animal model.And then started to resuscitate,with colloid and crystalloid infusion according to the proportion 1∶2,infusion rate of about 10 ～ 15ml/( kg · h),according to the blood pressure and heart rate,and proper adjustment according to the different requirements of each group conducted a blood transfusion.Monitoring based value,shock,shock treatment 30 minutes,60 minutes,120 minutes,180 minutes all time points,and various indexes of blood loss,blood transfusions,crystalloid and colloid fluid volume and so on.ResultsIn shock treatment observation group A late blood pressure,pH,BE,HCO3-,O2ER etc compared with the other three groups had obvious statistical differences ( P ＜ 0.05 ),group B with C and D two groups at the same time points each monitoring were no significant differences ( P ＞0.05 ).The volume of transfusion group C was most,compared with the other three groups were significant difference ( P ＜ 0.05 ),group D of blood transfusions than A,B two groups (P ＜ 0.05 ),groups A and B infused colloid fluid,crystal fluid volume than groups C and D ( P ＜ 0.05 ),each group blood lossed without significant difference.ConclusionScvO2 for controlled hemorrhagic shock rabbit resuscitation monitoring can guide controlled hemorrhagic shock rabbit of blood transfusions,according to ScvO2 ≤75％ transfusion with traditional according to Hb or blood loss transfusion trigger comparison,can achieve the same resuscitation effect,and can more accurately and individualized guide transfusion,reduce unnecessary blood transfusions,save resources.

Study on etiology of clinically diagnosed non A-E hepatitis / 中华实验和临床病毒学杂志

<p><b>BACKGROUND</b>To study etiology of clinically diagnosed non A-E hepatitis.</p><p><b>METHODS</b>HBV, TTV, human parvovirus B19, SENV DNA were detected by nested polymerase chain reactions (nPCR), while HGV, HCV RNA were tested by reverse transcription nested polymerase chain reactions (RT-nPCR).</p><p><b>RESULTS</b>Of 60 patients with clinically diagnosed non A-E hepatitis, 30 (50.0%) were HBV DNA positive alone, 10 (16.7%) HBV and TTV DNA positive, 6 (10.0%) HBV and B19 DNA positive; 1 (1.7%) HBV, SENV DNA and HCV RNA positive, 1 (1.7%) HCV RNA positive alone, 1 (1.7%) HCV RNA and B19 DNA positive, 2 (3.3%) B19 DNA positive alone, 1 (1.7%) TTV DNA positive alone, and the remaining 8 (13.3%) negative for all viruses. All the 60 patients were HGV RNA negative. There were no differences in serum biochemical markers of hepatitis B patients with or without TTV or B19 virus infection.</p><p><b>CONCLUSIONS</b>HBV is a major etiologic agent for the clinically diagnosed non A-E hepatitis. HGV, TTV, B19 and SEBV may not be associated with nonA-E hepatitis.</p>

Effect of Qizhu Oral Liquid on radiation injury in mice / 中成药

AIM: To observe the protective effect of Qizhu Oral Liquid on radiation injury in mice. METHODS: The model was made in mice by X-ray radiation. The white blood cells(WBC), bone marrow nucleated cells (BMNC) were measured. The weight of thymus and spleen were measured. RESULTS: Qizhu Oral Liquid could increase WBC and BMNC remarkably. It could increase the weight of thymus and spleen of mice signifcantly. CONCLUSION: Qizhu Oral Liquid is effective in protecting the X-radiation injury mice.

Study on pharmacodynamics of Wenjinghuayu Mixture / 中成药

Objective: To observe the therapeutic actions of Wenjinghuayu Mixture(Radix Angelicae Sinensis, Rhizoma Chuanxiong, Rhizoma Cyperi, Herba Leonur, etc.) on dysmenorrhea and irregular menstruation. Methods: The uterus and ovary of mice were weighted. The ear edema and writhing and isolated rat uterus were used for experiment models. Results: Wenjinghuayu Mixture could significantly increased the weight of uterus of mice. It had inhibitory effects on mice ear edema and could reduce the writhing of mice and rats. It had biphasic effect on rat's isolated uterine contraction. Conclusion: Wenjinghuayu Mixture has effects of analgesia and anti-inflammation and has biphasic effect on uterine contraction.
