Chinese Journal of Biochemical Pharmaceutics 2017;37(8):257-258,261
Objective To observe the effect of cefoperazone sulbactam on the efficacy inflammatory factors in patients with sepsis. Methods 80 cases of sepsis patients from January 2014 to April 2015, were double-blindly, randomized divided into control group(41 cases) and observation group(39 cases). The control group was treated with conventional treatment methods, the observation group was treated with cefoperazone sulbactam. After treatment, Leukocyte IL-6, IL-10, IL-1 and C- reactive protein (CRP) levels of interleukin and curative effect in the two groups were analyzed. Results After treatment, the levels of IL-6, IL-10, IL-1, CRP in the observation group were lower than those in the control group (t=15.555;t=11.122; t=9.379; t=34.782), the difference was statistically significant (P<0.05); The total effective rate in the observation group was 95.12%, which was significantly higher than that in the control group (76.93%), and the difference was statistically significant (P<0.05); The proportion of painless and severe pain in the observation group was significantly lower than that in the control group(76.93%), and the difference was statistically significant (P<0.05). Conclusion Cefoperazone sulbactam is effective in the treatment of sepsis, can improve the efficacy of treatment, it is a safe and effective treatment, should be promoted and used in clinical.

Objective To evaluate the accuracy of ultrasonographic measurement of the transverse diameter of the cricoid cartilage in selecting the cuffed endotracheal tube (ETT) size for pediatric patients.Methods A total of 120 pediatric patients of both sexes,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,aged 1 month-6 yr,with body mass index of 10.9-31.2 kg/m2,undergoing endotracheal intubation and general anesthesia,were divided into group A and group B,with 60 pediatric patients in each group.The pediatric patients were intubated with a cuffed ETT in two groups.The ETT size was selected based on the transverse diameter of the cricoid cartilage measured by ultrasonography in group A.The ETT size was selected according to the age-based formula in group B.A tracheal leak was detected after intubation to determine whether or not the ETT size selected was appropriate.ETTs were replaced when the actually selected ones were not appropriate,and the number of replacement was recorded.The development of intubation-related complications was also recorded.Results The accurate rate of cuffed ETT size selected at the first time was 95% in group A,and it was significantly higher than that in group B (60%) (P< 0.05).There was no significant difference in the incidence of intubation-related complications between the two groups (P>0.05).Conclusion Uhrasonographic measurement of the transverse diameter of the cricoid cartilage produces higher accuracy in selecting the cuffed ETT size for pediatric patients and is worthy of clinical application.

Background and purpose:Breast cancer is one of the most common carcinoma among female patients with high mortalities. Drug-resistance is the major reason that leads to chemotherapy failure in clinical practice. MCF-7/ADR is a multi-drug resistant cell line that was established on the basis of breast cancer cell line MCF-7. This research aimed to investigate the anti-apoptotic effect of c-fos in resistant breast cancer cell MCF-7/ADR, and to compare with its sensitive counterpart MCF-7.Methods:Doxorubicin with various concentrations was used to treat MCF-7 as well as its MDR- counterpart MCF-7/ADR. The growth inhibitory rate of MCF-7 and MCF-7/ADR wasdetermined by MTT assay. Additionally, RT-PCR was used to test the expression of P-gp and c-fos mRNA in MCF-7 and MCF-7/ADR; The expression of c-fos mRNA was detected by RT-PCR after 3 μmol doxorubicin treatment;We further established cell lines that stably interfered with c-fos, named MCF-7/ADR/si-fos-8B, MCF-7/ADR/si-fos-3D. Flow cytometry and MTT assay were used to investigate the apoptosis rate and inhibitory rate in these above cells under the treatment of 5-FU, CDDP or γ-radiation. At last, RT-PCR and Western blot analysis were used to detect the expression of bax, bcl-2, puma, p53.Results:The expression of c-fos and P-gp (MDR-1) was up-regulated in MCF-7/ADR, compared with its sensitive counterpart MCF-7. Additionally, the resistant fold of MCF-7/ADR to doxorubicin was nearly 40; The expression of c-fos was gradually up-regulated after 3 μmol doxorubicin treatment; The sensitivity to drugs (5-FU and CDDP) was increased after c-fos interference while the apoptosis rate was also increased after 5-FU, CDDP and γ-radiation treatment. RT-PCR and Western blot analysis indicated that up-regulation ofbax,puma,p53 after c-fos interference while the expression of bcl-2 was down-regulated.Conclusion:c-fos may act as an anti-apoptotic protein in resistant breast cancer cell line MCF-7/ADR by regulating the expression of apoptosis related proteins, and may play a vital role in the formation of multi-drug resistance phenotype.

Objective:To investigate the clinical phenotypes, imaging features and pathogenic variants of ANO10 gene related autosomal recessive spinocerebellar ataxia-10 (SCAR10).Methods:A cohort of 30 probands of autosomal recessive cerebellar ataxia pedigrees from China-Japan Friendship Hospital from 2018 to 2020 were collected. Friedreich ataxia and other causes of acquired ataxia were excluded, then probands were detected by whole-exome sequencing (WES), and potential pathogenic variants were confirmed by Sanger sequencing and validated in all family members. Clinical phenotypes and auxiliary examinations of the patients were analyzed in detail.Results:A pedigree of SCAR10 caused by ANO10 gene mutations was identified through WES. The 40-year-old male proband of this pedigree carried compound heterozygous mutations: c.1219-2A>C and c.1163-2A>G of the ANO10 gene, both of which were novel mutations, and Sanger sequencing revealed these two mutations were respectively inherited from his healthy parents. Bioinformatic analysis predicted these two mutations were pathogenic. The proband exhibited progressive unsteady walk, dysarthria, mild cognitive impairment. His plasma total coenzyme Q 10 was decreased (0.76 μg/ml). Brain magnetic resonance imaging showed remarkable cerebellar atrophy. Conclusions:Through WES, a SCAR10 patient caused by novel compound heterozygous mutations of ANO10 gene was identified, which is rare in China. The main clinical manifestation was progressive cerebellar ataxia and cognitive decline, and brain image showed remarkable cerebellar atrophy.
