Objective To find the correlative factors which induce breath failure in acute tetramine poisoning cases, and to work out a right treatment scheme for these cases. Methods 47 cases were clinically diagnosed as slight, middling and severe poisoning, separately. The tetramine concentration in blood was compared between the three groups to reveal the relationship between blood concentration of tetramine and breath failure. Patients with breath failure were treated with muscle relaxant plus mechanical ventilation. Repeated hemoperfusions were given to the severe poisoning patients. Results No breath failure occured in both slight and middling groups, while in severe poisoning group, breath failure happened in 33.3% (4/12) patients aged below 15, and in 31.8% (7/22) adult patients aged above 15. Repeated hemoperfusion declined the tetramine concentration in blood, and gave a better effect than with CVVH or CVVHD treatment. muscle relaxant plus mechanical ventilation may control the symptom of twitching completely, and prevent from breath failure effectively. Conclusion Breath failure in acute tetramine poisoning cases was induced by systemic twitching and high blood tetramine concentration. It is very important to grade the poisoning cases according to poisoning degree. Repeated hemoperfusion is the best for blood purification. muscle relaxant plus mechanical ventilation may reduce the mortality effectively.

Objective To explore the common pathogens distribution and the drug resistance pattern in vitro from cerebrospinal lfuid culture in children. Methods The results of cerebrospinal lfuid culture in hospitalized children from January 2007 to December 2014 were retrospectively analyzed. Bacteria identiifcation and antimicrobial susceptibility were assayed by Vitek system from Bio Mrieux Company. Some bacterial strains were tested by disk diffusion method. Results Cerebrospinal lfuid from 23099 patients were tested at least one time during research period. 671 strains of bacteria were isolated with positive rate of 2 . 9%, among which there were 579 strains of gram positive bacteria ( 86 . 3%) and 92 strains of gram negative bacteria ( 13 . 7%). The top ifve bacteria were coagulase negative Staphylococcus ( 399 strains, 58 . 9%), Micrococcus ( 37 strains, 5 . 5%), Streptococcus pneumoniae (34 strains, 5.1%), Escherichia coli (32 strains, 4.8%), and Enterococcus faecium (26 strains, 3.9%). The positive rates of cerebrospinal lfuid culture in 8 consecutive years showed a downward trend (χ2?=?10 . 410 , P=?0 . 001 ). The positive rates of coagulase negative Staphylococci showed annual decline trend (χ2?=?31 . 200 , P

AIM:To study the purified factors of Guanxinning for Injection(Radix et Rhizoma salviae miltiorrhizae,Rhizoma Chuanxiong,etc). METHODS: The total of salvianolic acid B、protocatchuci aldehyde and ferulic acid were used to evaluate for the study of type of macroporous adsorption resin,sample volume,the ratio of diameter to height,pH value and sample consistency etc. RESULTS: pH value Guanxinning extract was adjusted to 3.0,through D101 resin finally reached the ratio of diameter to height 1∶2,4 times of water was applied to elution and then 3 times of 70% ethanol for re-elution and collected. CONCLUSION: These factors are approprite for purifying Guanxinning for Injection.

Objective To study the inhibit effect of survivin short hairpin RNA on the survivin mRNA and protein expression of gallbladder carcinoma cells.Methods Human gallbladder carcinoma cells(GBC-SD) were transfected with recombinant plasmid.RT-PCR and Western blot were used to analyze the changes in(expression) levels of survivinmRNA and protein.Results The size of the PCR product was 350bp.DNA(sequencing) showed that the sequence of recombinant vector pshRNA-survivin was successfully constructed and suppressed the expression of(GBC-SD) survivinmRNA.Conclusions The recombinant plasmid constructed can inhibit the expression of survivinmRNA in transfected cells.This provides a new method and material for the biological therapy of cancer.

OBJECTIVE:To discuss the median effective concentration(EC50)of ropivacaine caudal motor block. METHODS: The EC50 of ropivacaine caudal epidural block was determined with sequential experimental method. RESULTS:The EC50 of ropivacaine caudal block was 0.22%(95%CI ranged from 0.216% to 0.235%). CONCLUSION:Canales sacralis injected with 0.20%～ 0.22% ropivacaine is suitable for bladder endoscopic examination in out-patient.

Objective To investigat the relationship between PON_1 192 Gln-Arg gene polymorphisms and coronary artery lesions in Shaanxi Han Chinese.Methods A total of 222 cases with one or more than two branches narrow(≥50%) and 164 cases with no coronary artery narrow(0.05).Conclusion There was no relationship between PON_(1) 192 Gln-Arg gene polymorphisms and Shaanxi Han patients with coronary heart disease.

Objective To evaluate the possibility and reliability of laparoscopic management of cholelithiasis merging extrahepatic and acalculous and benign obstructive jaundice. Methods Eleven patients with cholelithiasis merging extrahepatic and acalculous and benign obstructive jaundice who underwent laparoscopic management were retrospectively studied.Results Ten cases were successful with laparoscopic management,among the total,4 patients were underwent laparoscopic cholecystectomy (LC),6 cases were experienced LC and laparoscopic common bile duct exploration (LCBDE).One case was converted to open operation.No serious complications were observed.All the patients were cured after the operative treatment.None of the complications could be traced after follow-up for 6 months. Conclusions Cholelithiasis merging extrahepatic and acalculous and benign obstructive jaundice is a challenge to laparoscopic surgeons.Intraoperative diagnosis is very difficultly,but very important.It is better prognosis by careful and skilled operators and reasonable operative method to be chose.

Objective To elucidate the clinical and pathological characteristics of patients with mercury poisoning-associated glomerulonephropathy. Methods Seven patients with mercury poisoning-associated glomerulonephropathy were enrolled in this study. The pattern of mercury exposure, feature of mercury toxicity, and clinicopathological presentation of the kidneys were investigated. Results They were all female, averaged (28.9 ±8.1) years old. Skin-whitening cream was the only cause of mercury poisoning. Proteinuria occurred 5 to 8 months after exposure. Serum mercury were 27.0 to 98.0 μg/L, and spot urinary mercury were 34.4 to 204.0 μg/L. The presentation of all the patients was mild to moderate edema with proteinuria and decreased serum albumin level. Five patients (5/7) were diagnosed as nephrotic syndrome. Six patients underwent renal biopsy: 3 cases with minimal change disease, 2 cases with membranous nephropathy and 1 case with focal segmental glomerular sclerosis. All the patients were administrated chelation therapy with sodium dimercaptopropanal sulfonate or sodium dimercaptosuccinic acid for 3 to 7 courses. They got complete remission by 3 to 5 weeks treatment. Conclusions Patients in this study with glomerulonephropathy induced by mercury poisoning are all from skin-whitening cream exposure. Mild to moderate edema and proteinuria are the common clinical pattern. Minimal change disease, membranous nephropathy and focal segmental glomerular sclerosis are found pathologically. Chelation therapy is effective.
