ABSTRACT
Objective To compare the clinical effect of penehyclidine hydrochloride and atropine in the treatment of acute organophosphorus pesticide poisoning.Methods 86 patients with organophosphorus pesticide poisoning were selected and randomly assigned to the observation group and the control group according to the digital table,43 cases in each group.The two groups were given conventional treatment,while the control group was treated with atropine,the observation group was given penehyclidine hydrochloride.The disappearance time of main symptoms, rescue success rate and adverse reactions of the two groups were observed.Results After salvage treatment, the rescue success rate of the observation group was 97.8%,which of the control group was 88.4%,the difference was statistically significant (x2=1.433,P<0.05).The disappear time of M like symptoms,N like symptoms and central nervous system symptoms in the observation group was significantly shorter compared with the control group (all P<0.05).The number of drugs,dosage,cholinesterase recovery time and hospitalization time between the two groups had statistically significant differences (P<0.05).The incidence rates of blurred vision,restlessness,heart rate and urinary retention in the control group were significantly higher than those in the observation group (all P<0.05).Conclusion Penehyclidine hydrochloride for acute organophosphorus pesticide poisoning can significantly reduce the incidence of symptoms,shorten the disappearance time of symptoms,reduce hospitalization time,improve the efficacy of rescue,reduce the incidence of adverse reactions, it is safe,effective and has great clinical significance.
ABSTRACT
Objective To study the effect of laparoscopic myomectomy on the curative effect and postoperative rehabilitation of patients with uterine fibroids (UM).Methods From March 2014 to March 2016, selected 84 patients with UM in the people's hospital of Baoding Xushui district were divided into observation group (n=43) and control group(n=41) according to the different operation procedures, the observation group were treated with laparoscopic myomectomy and the control group were treated with open uterine fibroids.Serum T cell subsets (CD4+, CD8+, CD4+/ CD8+) between the two groups before and 1 day after operation were compared, and CA125, Cor, IL-1β levels, and surgery condition, postoperative recovery, complicationsand postoperative 12 months of recurrence were statistically compared.Results The serum CD4+, CD8+, CD4+/CD8+ levels in the observation group were significantly higher than those in the control group at 1 day after operation, the difference was statistically significant (P<0.05);the first exhaust time and hospitalization of the observation group were significantly shorter than those of the control group, and the intraoperative blood loss and postoperative pain score (VAS) were significantly lower than those in the control group (P<0.05);The incidence of postoperative complications in the observation group (6.98%, 3/43) was significantly lower than that in the control group (26.83%, 11/41), by follow-up, the recurrence rate (2.33%, 1/43) was lower than that of the control group (19.51%, 8/41), the difference was statistically significant (P<0.05).Conclusion Treatment of uterinemyoma using laparoscopic myomectomy gets a significant effect, and the body inflammation, stress response lighter and the effect of immune function is small, which can reduce the postoperative complications and recurrence rate and promote the rehabilitation of patients, and less impact on immune function.
ABSTRACT
Objective To analyze the complexity of molecular structure in porcine T cell receptor gene and its similarity compared to humans.Method Based on the gene of porcine T cell receptor alpha chain ( TCRα) from the Gen-Bank database, 93 swine T cell receptor alpha chain genes ( STA) were cloned by reverse transcription-polymerase chain reaction (RT-PCR) from porcine peripheral blood lymphocytes, lymph nodes and spleen.Result Sequence analysis showed that STA genes all contain a domain of variable signal peptide and V, hypervariable J and conservative C.Howev-er, nucleotide sequence of STA was not completely identical with only 68.4%to 98.7%homology among genes, and had extremely sophisticated polymorphism and diversity.This was accord with the genetic structure of TCRαchain.Molecular structure, genetic evolution and classification of these genes were carried out according to the homology of TCRαgene, which all have several sites and zones of mutation on the domain of signal peptide, FR1 and CDR1, FR2 and CDR2, FR3 and CDR3.Analysis of similarity and classification of TCRαV domain(STAV)and J domain (STAJ) of Hezuo minipig u-sing IMGT/V-QUEST tools compared with those of humans found the genetic evolution relationship that was closer, and each of TRAV and TRAJ also found to have a corresponding fragment of humans, ever in 92% of similarity of TRAV be-tween swine and humans.Conclusion Our results indicate that inbred Hezuo minipig possesses genetic diversity against complicated environment of microbes in healthy status, and Hezuo minipig is suitable as an animal model for research on human immunology and diseases.
ABSTRACT
OBJECTIVE:To establish a HPLC method for the determination of the principal agent in balsalazide tablets and detection of the related substances.METHODS:The determination was conducted on C18 column with column temperature at 40℃.The mobile phase was composed of 0.1 mol/L ammonium dihydrogen phosphate-acetonitrile(82∶18) with flow rate at 1.0ml/min and wavelength at 360nm.RESULTS:Balsalazide and its related substance could be absolutely separated through this method.The liner range of the balsalazide was 20.0～150.0?g/ml(r=0.9 999).The average recovery was 99.6%(RSD=1.19%).CONCLUSION:The method was simple,fast,accurate,specific,reproducible and free from the interference of excipients in the determination of principal agent,and which can be adopted for the determination of the principal agent in balsalazide tablets and detection of the related substances.
