OBJECTIVE: To establish a multiplex genotyping system of mtDNA SNP. METHODS: A multiplex analysis system of 16-plex mtDNA SNP loci was established with allele specific PCR and capillary electrophoresis genotyping technology. Fifty samples from unrelated Chinese Han individuals were typed with the multiplex system. The multiplex assay was validated by comparing with the direct sequencing method. RESULTS: The genotypes of all 50 samples were correctly determined by the multiplex system. The optimal genotypic graphs were obtained with an input DNA of 0.5-10 pg, and the typing results were completely consistent with those by direct sequencing method. CONCLUSION The established multiplex system by allele specific PCR has high sensitivity, operational simplicity and high accuracy. It provides an effective and high output method for mtDNA SNP typing.

BACKGROUND: This study aimed to observe the effect of hemoperfusion (HP) cartridge on different internal environment indicators at different time points in patients with acute blood poisoning and to find alternative indicators for the detection of blood poisoning. METHODS: The levels of internal environment indicators (blood pH, PvCO2, PvO2, blood lactate, potassium, free calcium, bicarbonate, and blood glucose) before and after HP treatment were recorded for patients with acute poisoning at time points of 30 minutes and 120 minutes. After calculating the difference value δ, the statistical software was used to analyze the statistical difference of the influencea-v caused by HP cartridge at two time points. According to the formula, adsorption rate %= —— ×100, thea adsorption rate of each indicator was calculated respectively. RESULTS: The difference of indicators at different time points in inlet and outlet such as blood glucose, free-calcium, and lactate was statistically significant (P<0.05), but the difference in indicators such as pH, PvCO2, PvO2, potassium, sodium, and bicarbonate was not statistical y significant (P>0.05). CONCLUSION: During HP treatment, the indicators of blood glucose, free-calcium and lactate were significantly affected by HP cartridge, and the effect varies with time.

Objective To explore the changing trend of Ia on monocyte, lymphocyte apoptosis rate, TNF-α and IL-6 in abdominal aorta of burned rats with delayed resuscitation and the influence of application of carbachol on them. Methods Adult male Wistar rats were randomly divided into normal control group(n =8), scald group(n =48) and scald with carbachol treatment group(n =48). In latter two groups, rats were inflicted with 30% total body surface area (TBSA) full-thickness scald and delayed fluid resuscitation. All scald rats were sacrificed at the 6th hours or 1st, 2nd, 3rd, 7th, 14th day after scald, with 8 rats at each time point. Expression of Ia antigen on monocyte and lymphocyte apoptosis rate were determined by direct immunofluorescence on a flow cytometer, and TNF-α and IL-6 was measured by ELISA. Results Expression of la on monocyte was obviously lower than that of controls. The lowest levels were recorded on the 6th hours and 1st day after scald. Subsequently, Ia was elevated gradually, but still lower than that of normal rats(P <0. 01). After administration of carbachol, Ia expression was obviously promoted, compared with the simple scald group (P <0. 01). Lymphocyte apoptosis rate, TNF-α and IL-6 was higher than that of controls(P <0. 01). After administration of cavachol, , lymphocyte apoptosis rate and TNF-α and IL-6 was obviously down-regulated on the 6th hours, 1st day, 2nd day and 3rd day after scald injury, compared with the simple scald group (P < 0. 01 or 0. 05). Conclusion After severe burn with delayed fluid resuscitation, there is a low la expression, high lymphocyte apoptosis rate and increased releasing of proinflammatory cytokine. Immune function was suppressed. Carbacho] could improve the immune function of scald rats with delayed fluid resuscitation.

The results of open-field test,step-through passive avoidance task and radial-arm maze experiment showed that changes of locomotor activity,anxiety-related behaviour and ability of learning and memory were associated with the increased apoptosis of neurons in hippocampus in rats with perinatal hypothyroidism.

Sepsis is a systemic inflammatory response syndrome resulting from a host response to infection. The early stage of sepsis is characterized by excessive inflammatory response, accompanied by immune dysfunction characterized by aggravating cellular immunosuppression. The vast majority of patients with sepsis survive the initial excessive inflammatory response, but die of hospital-acquired infection, opportunistic pathogenic bacteria infection, latent virus reactivation, and multiple organ dysfunction syndrome. These facts indicate that immunosuppression may be a significant cause of exacerbation of the illness even death of the septic patients. The primary cellular mechanisms in inducing immune dysfunction include immune dysfunction of T lymphocytes, negative regulation of regulatory T lymphocytes and dendritic cells, and damage of intestinal mucosa associated lymphoid tissue. Xuebijing injection is a complex Chinese patent medicine, which is widely used in the treatment of sepsis. It has a potential immunoregulation ability, as well as effects on bacteriostasis, anti-endotoxin and anti-inflammation. Its target and mechanism of action need to be explored further.
