1.Rhabdomyolosis and its pathogenesis
World Journal of Emergency Medicine 2012;3(1):11-15
BACKGROUND: Rhabdomyolysis may cause severe damage to the human body because of acute renal failure, fatal heart rhythm disturbances, hypovolemic shock, disturbances of electrolyte balance, metabolic acidosis, hyperthermia, disseminated intravascular coagulation, etc. Drugs and toxins are the most common factors for the disease. This article aimed to review the prognosis of rhabdomyolysis. DATA SOURCES: Based on the reported studies of cell and molecular biology, we reviewed the clinical presentations, laboratory findings, and mechanisms of rhabdomyolysis in the Pubmed. RESULTS: The clinical symptoms of rhabdomyolysis were dependent on the severity of the condition and whether kidney failure develops. Since the necrosis and dissolution of muscle cells, entocytes such as myoglobin, creatine phosphokinase (CPK), electrolytes, proteins and non-protein substances were released into the plasma, the detection of the entocytes may contribute to the early diagnosis of rhabdomyolysis. CONCLUSION: Despite the etiology of the disease is multifactorial, the potential causes of rhabdomyolysis share the same pathophysiological pathway involving an increase in intracel ular calcium.

Neonatal respiratory distress syndrome(NRDS)is the most critical disease in neonatal pe-riod.Studies have proved that genetic factors play an important role in the pathogenesis of NRDS.More and more proteins and genes which are associated with NRDS are researched.This article mainly reviewed the re-search of surfactant protein,ATP-binding cassette transporters A3,mannose-binding lectin,thyroid transcrip-tion factor-1and NRDS.

Objective To investigate the relationship between single nucleotide polymorphisms of surfactant protein C(SP-C)gene and respiratory distress syndrome(RDS)in the Han nationality newborns in Inner Mongolia and whether there is a mutation occurs on SP-C gene exon 4 and 5.Methods One hundred newborns with RDS(case group)and 100 newborns without RDS(control group)were selected.PCR gene analysis was used to establish the genotype and allele frequencies of exon 4 (T138N)and 5 (S186N)on SP-C.Results In the Han nationality newborns of Inner Mongolia region,there was no mutation on SP-C gene exon 4 and 5.Exon 4(T138N)on SP-C could be checked out three genotypes:namely AA,AC and CC.The genetic polymorphisms of exon 4 on SP-C were not statistically different between the case group and the control group(χ2 ﹦0.744,P ﹦0.689).Besides,exon 5(S186N)on SP-C could also be checked out three genotypes:namely AA,AG and GG.The genetic polymorphisms of exon 5 on SP-C were also not statistically different between the case group and the control group(χ2 ﹦0.770,P ﹦0.681 ).Conclusion There is no mutation on SP-C gene exon 4 and 5.The genetic polymorphism of exon 4 and 5 on SP-C displays no signifi-cant correlation with RDS of the Han nationality newborns in Inner Mongolia.

In this study, three methods for identification of E.coli were compared. The conventional method was employed to select and identify the suspicious E.coli isolates from a fecal sample. PCR based ARDRA analysis was then carried out to distinguish these E.coli isolates, E.coli MG1655 and other bacterial species. All the potential E.coli isolates and E.coli MG1655 had the identical ARDRA banding pattern while the other bacterial species showed the different patterns.The result indicated that the ARDRA analysis was consistent with the traditional method for identification of E.coli and could be the practical method for distinguishing E.coli from other intestinal bacterial species. The ERIC-PCR analysis provided abundant polymorphism between different E.coli isolates, and might be a powerful approach for elucidating the genetic diversity among isolates of the same species.

Objective To investigate whether CD4~+CD25~(high)regulatory T cells(tregs)were increased in the tumor tissue and peripheral blood of prostate cancer patients.Methods The prevalence of CD4~+CD25~(high)regulatory T cells inside the prostate tumor was detected compared with benign tissue from the same prostate.Furthermore,the frequency of CD4~+CD25~(high)regulatory T cells in peripheral blood was detected in prostate cancer patients compared with normal donors.Results Moreover,CD4~+CD25~(high)regulatory T cells from blood and supernatants from cultured prostate tumor tissue samples exhibited immunosuppressive function in vitro.CD4~+CD25~(high)T normal peripheral blood cells were found for the ratio was(0.5?0.1)%.Lower than the proportion of T cells in peripheral blood of patients with CD4~+CD25~(high)was(2.3?0.7)%,P

ObjectiveTo demonstrate the effect of moderate hypothermia and doule carotid ice applied to acute intracerebral hemorrhage (ICH) and the best opportunity of treatment.Methods174 cases with ICH were randomly divided into treated group and control group, 87 cases for each group. Each case of both groups was treated by routine therapy, moreover, all cases in treated group were treated by moderate hypothermia (MHT).The clinical effect and prognosis between treated group and control group were contrasted,so to do between the cases in the treated group who were treated no more than 3 hours and more than 3 hours after attack.ResultsCompared with the control group, the neurological function improved in the treated group(P<0.05), as well as survival rate and recovery(P<0.05).Cases who treated no more than 3 hours after attack was better than that of more than 3 hours(P<0.05).ConclusionModerate hypothermia can effectively ease the neurologic deficits after ICH, decrease mortality and disable rate.The best therapy time is within 3 hours after ICH.

ObjectiveTo observe effect of head and body acupuncture and moxibustion on stroke.Methods183 stroke patients were randomly divided into 3 groups, head acupuncture and moxibustion, body acupuncture and moxibustion, and head body acupuncture and moxibustion. After two months treatment, effects of 3 groups were evaluated.ResultsThere were no differences between head group and body group, body group and head body group, but there was significantly difference between head body group and head group (P<0.05).ConclusionThe head body acupuncture and moxibustion can gain the best clinical effect on stroke patients compared with simply head or body acupuncture and moxibustion.
