AIM: To compare the effects of total intravenous anesthesia and balanced anesthesia on stress response on suspensive laryngoscope vocal cords surgery. METHODS: Thirty patients undergone microlaryngeal surgery were randomly divided into two groups(n=15). Analgesia and amnesia slow induction was used in all patiens with nosal incubation. During maintenance of anesthesia, propofol, remifentanil and scopolamine were used in total intravenous anesthesia group(group TIVA); fentanyl, scopolamine and isoflurane were used in balanced anesthesia group(group BAL). Record the data of each group,including base data, after induction, end of tracheal intubation,3 min after intubation, setting the suspensive laryngosopy, 3 min after setting the suspensive laryngosopy, removing the trachea, MAP, HR of each time, the time of recovery. The blood concentrations of epinephrine (E), noradrenalin(NE),cortisol,IL-6 were measured at each time point of base data, end of tracheal intubation, setting the suspensive laryngosopy, 3 min after setting the suspensive laryngosopy. RESULTS: There is no significant difference of HR, MAP, blood concentration of E,NE, cortisol, IL-6 at end of tracheal intubation compared with base data. AT setting the suspensive laryngosopy,3 min after setting the suspensive laryngosopy, HR, MAP, blood concentrations of E, NE, cortisol, IL-6 in group BAL were all higher than that of base data,and were also higher than group TIVA at the same time. The recovery time of group TIVA was shorter than that of group BAL. CONCLUSION: Analgesia and amnesia slow induction with nosal intubaion and maintenance with remifentanil, propofol can inhibit sudden change of hemodynamics and stress response of intubation and setting the suspensive laryngoscope, with quicker recovery .It is an ideal anesthesia method for suspensive laryngoscope vocal cords surgery.

and indexes of the ROI which had significant difference between the groups. Results In the white matter regions, MD, D∥and D⊥in many regions of AD group were increased significantly than the control group, and the differences were statistically significant. MD and D ⊥ showed more abnormalities, including the SCC, PCB, and FWM. Meanwhile, MK, K∥and K⊥in many regions of AD were decreased, and the differences were statistically significant. K ⊥ showed more abnormalities, including the SCC, FWM and TWM. In the gray matter regions, MD, D∥and D⊥of hippocampal of the AD group were all increased than the control group. However, it showed that MK and K⊥of the thalamus in AD group were 0.99 ± 0.10, 1.00 ± 0.11, respectively, and both increased than the control group (the value of MK and K⊥were 0.90±0.06, 0.90±0.07, respectively), and the differences were statistically significant (t values was 3.31, 3.57 respectively, and both P values were<0.01). The indexes of different ROI had correlations with the MMSE scores. There were more regions in kurtosis indexes correlated with the MMSE scores than the diffusion indexes. The strongest correlation among the analyses was MK of the SCC (r=0.73, P<0.05). Conclusions This study based on DKI found the complex alterations aroused by microstructural changes were not only in the white matter but also the gray matter of the AD patients, especially the increased kurtosis of the thalamus, and this suggested that the microstructural complexity of it was increased. Moreover, it also suggested that indexes of DKI had varied sensitivity in detecting different diffusion alterations.

OBJECTIVE:To provide reference for improving the level of pediatric drug supply and guarantee. METHODS:Questionnaire survey about the situation and causes of pediatric drug shortage was conducted in 13 third-level hospitals of Jiangsu province [directors of pharmacy department(or drug purchasers)and clinical pharmacists of each surveyed hospital]. The survey da-ta were analyzed statistically so as to provide suggestions. RESULTS:A total of 26 questionnaires were distributed,and 26 effec-tive questionnaires were collected with effective recovery rate of 100%. In 13 hospitals,special drugs for children were mostly less than 5% of hospital drug list. There were 82 kinds of special drugs for children(containing hospital preparation),mainly including Chinese patent medicine(35.37%),drugs for respiratory system(12.20%),vitamin,mineral substance and enteral and parenteral nutrient solution(10.98%). The most types of anti-infective drugs,antineoplastics,nervous system drugs and psychotropic drugs, digestive system drugs were in shortage among 126 pediatric drugs in shortage(8.73%). The reasons for pediatric drug shortage mainly included price(38.10%),production break(32.54%),failure to bid or no supply(13.49%). The shortage of cheap drugs with price of 0.01-10.00 was the most serious,accounting for 57.94% of the varieties in shortage supply. Respondents thought that special drug shortage most affected clinical treatment(38.46%),followed by poisoning rescue drugs(30.77%)and orphan drugs(15.38%). CONCLUSIONS:Special drugs for children account for a very small proportion in the hospital drugs list. Pediatric drug shortage is affected by many factors. Cheap drug shortage is the most serious. The shortage of special drugs for children and poison-ing rescue drugs is considered to have a great impact on clinical treatment. It is suggested to establish special drugs for children pro-tective policy,improve drug circulation,promote pediatric drug clinical trial and intensify the research and development of special drugs for children so as to guarantee pediatric drug supply.

Objective:To investigate the bacterial composition and antimicrobial resistance profile of clinical isolates from bloodstream infections in China.Methods:The clinical bacterial strains isolated from blood culture were collected during January 2020 to December 2020 in member hospitals of Blood Bacterial Resistant Investigation Collaborative System (BRICS). Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical Laboratory Standards Institute(CLSI, USA). WHONET 5.6 was used to analyze data.Results:During the study period, 10 043 bacterial strains were collected from 54 hospitals, of which 2 664 (26.5%) were Gram-positive bacteria and 7 379 (73.5%) were Gram-negative bacteria. The top 10 bacterial species were Escherichia coli (38.6%), Klebsiella pneumoniae (18.4%), Staphylococcus aureus (9.9%), coagulase-negative Staphylococci (7.5%), Pseudomonas aeruginosa (3.9%), Enterococcus faecium (3.3%), Enterobacter cloacae (2.8%), Enterococcus faecalis (2.6%), Acinetobacter baumannii (2.4%) and Klebsiella spp (1.8%). The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant coagulase-negative Staphylococcus aureus were 27.6% and 74.4%, respectively. No glycopeptide- and daptomycin-resistant Staphylococci were detected. More than 95% of Staphylococcus aureus were sensitive to rifampicin and SMZco. No vancomycin-resistant Enterococci strains were detected. Extended spectrum β-lactamase (ESBL) producing Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis were 48.4%, 23.6% and 36.1%, respectively. The prevalence rates of carbapenem-resistance in Escherichia coli and Klebsiella pneumoniae were 2.3% and 16.1%, respectively; 9.6% of carbapenem-resistant Klebsiella pneumoniae strains were resistant to ceftazidime/avibactam combination. The prevalence rate of carbapenem-resistance in Acinetobacter baumannii was 60.0%, while polymyxin and tigecycline showed good activity against Acinetobacter baumannii. The prevalence rate of carbapenem-resistance of Pseudomonas aeruginosa was 23.2%. Conclusions:The surveillance results in 2020 showed that the main pathogens of bloodstream infection in China were gram-negative bacteria, while Escherichia coli was the most common pathogen, and ESBL-producing strains declined while carbapenem-resistant Klebsiella pneumoniae kept on high level. The proportion and the prevalence of carbapenem-resistant Pseudomonas aeruginosa were on the rise slowly. On the other side, the MRSA incidence got lower in China, while the overall prevalence of vancomycin-resistant Enterococci was low.
