group was (1.20 ± 1.09),(1.09 ± 1.04), (0.86 ± 0.42), (1.89 ± 1.30) and that of the control group was (2.40 ± 1.87), (2.34 ± 1.71), (1.60 ± 1.33),(3.49 ± 1.72) respectively, which had statistical significance between the two groups (t=3.139-4.390, P<0.01). the Blood CRP values and CRP positive rate in the observation group, were (6.34±2.74) and 17.14%(6/35) respectively and which of the control group were (10.35±7.37) and 42.86%(15/35), the difference of the two groups was statistically significant (t=2.881, P<0.01 andχ2= 5.250, P < 0.05). Conclusions Topical treatment of acute cellulitis with honey can effectively improve the clinical symptoms, reduce the level of c-reactive protein, which is better than magnesium sulfate wet compress.

OBJECTIVE:To provide reference for rational use of antibiotics in clinic.METHODS:The quarterly information about the consumption of antibiotics in inpatients of our hospital during Jan.2012-Dec.2016 were collected from Center for Antibacterial Surveillance.DDDs of various antibiotics and Escherichia coli were analyzed statistically;the detection of E.coli,producing ESBLs and drug resistance during the same period were also analyzed statistically.The correlation between DDDs of antibiotics and resistance rate was investigated by Pearson test.RESULTS:During 2012-2016,DDDs of cephalosporins was the highest in inpatients of our hospital,followed by cephamicins and macrolides.Total DDDs of antibiotics showed a decreasing trend and a slight rebound in 2016.After 2013,DDDs of most antibiotics were basically same to the change of total DDDs.However,DDDs of compound preparations of penicillin and β-lactamase inhibitors,cephalomycm,carbapenems and glycopeptides showed an upward trend.In 2012,DDDs of second-generation cephalosporin was the highest among cephalosporins;since 2013,DDDs of first-generation cephalosporin was the highest in this category.Anti-E.coli drugs included piperacillin sodium and tazobactam sodium,ceftazidime,ceftriaxone,cefepime,cefoxitin,aztreonam,meropenem,gentamicin,levofloxacin.Among anti-E.coli drugs,DDDs of cefatriaxone was the highest in 2012,while that of cefoxitin was the highest in 2016;the consumption of aztreonam decreased most obviously.During 2012-2016,110,132,104,131,243 strains of E.coli were detected in our hospital respectively.The rate of producing ESBLs decreased to 56.6％,57.0％,50.6％,48.4％,45.0％.E.coli was highly resistant to ampicillin,cefazolin,ceftriaxone and compound sulfamethoxazole,while poorly resistant to piperacillin sodium and tazobactam sodium,cefoxitin,imipenem and amikacin.Resistance rate of piperacillin sodium and tazobactam sodium was positively correlated with DDDs of ceftriaxone,aztreonam,gentamicin,levofloxacin,cephalosporins (fast-,third-generation cephalosporins),tetracyclines,quinolones and total DDDs (r were 0.880 to 0.929,P＜0.05).Resistance rate of ceftazidime was positively correlated with DDDs of ceftriaxone,aztreonam,gentamicin,levofloxacin,cephalosporins (fast-,second-,third-generation cephalosporins),tetracyclines,quinolones and total DDDs (r were 0.888 to 0.991,P＜0.05).Resistance rate of cefepime was positively correlated with DDDs of aminoglycosides(r was 0.901,P＜0.05).Resistance rate of gentamicin was negatively correlated with DDDs of compound preparations of penicillin and β-lactamase inhibitors,cefepime (r were-0.914,-0.921,P＜0.05).Resistance rate of imipenem was negatively correlated with DDDs of ceftriaxone,aztreonam,gentamicin,levofloxacin,cephalosporins (fast-,second-,third-generation cephalosporins),aminoglycosides,tetracyclines,quinolones and total DDDs (r were-0.994 to-0.878,P＜0.05).Resistance rates of anti-E.coli drugs were all independent from their DDDs (P＞0.05).The rate of E.coli producing enzyme was positively correlated with resistance rate of gentamicin(r was 0.955,P＜0.05),while was independent from resistance rate or DDDs of other drugs (P＞0.05).CONCLUSIONS:After antibiotics special rectification,total consumption of antibiotics in inpatients of our hospital show a downward trend,and the varieties also change greatly.Although drug resistance is serious,the rate of producing enzyme is decreasing.Antibiotics should be selected carefully according to the monitoring data of bacterial resistance,drug sensitivity test results,the correlation between the consumption of antibiotics and resistance rate so as to reduce the occurrence of bacterial resistance.

OBJECTIVE: To present on a prenatally diagnosed case with complex structural rearrangements of chromosome 8. METHODS: Chromosome karyotyping, chromosomal microarray analysis (CMA) and fluorescence in situ hybridization (FISH) were carried out for a fetus with increased nuchal thickness. RESULTS: The karyotype of the amniotic fluid sample showed extra materials on 8p. FISH revealed a centromeric signal at the terminal of 8p with absence of telomeric signal. CMA revealed partial deletion of 8p23.3 [(208049_2256732)×1], partial duplication of 8p23.3p23.2 [(2259519_3016818)×3], and partial duplication of 8q [8q11.1q12.2(45951900_60989083)×3]. CONCLUSION The complex structural rearrangements of chromosome 8 in this case has differed from the commonly seen inv dup del(8p).

We report a complete genomic sequence of rare isolates (minor genotype) of the SARS-CoV from SARS patients in Guangdong, China, where the first few cases emerged. The most striking discovery from the isolate is an extra 29-nucleotide sequence located at the nucleotide positions between 27,863 and 27,864 (referred to the complete sequence of BJ01) within an overlapped region composed of BGI-PUP5 (BGI-postulated uncharacterized protein 5) and BGI-PUP6 upstream of the N (nucleocapsid) protein. The discovery of this minor genotype, GD-Ins29, suggests a significant genetic event and differentiates it from the previously reported genotype, the dominant form among all sequenced SARS-CoV isolates. A 17-nt segment of this extra sequence is identical to a segment of the same size in two human mRNA sequences that may interfere with viral replication and transcription in the cytosol of the infected cells. It provides a new avenue for the exploration of the virus-host interaction in viral evolution, host pathogenesis, and vaccine development.

ObjectiveTo explore the influence of the core symptoms of attention deficit hyperactivity disorder （ADHD） on behavioral problems of children with ADHD propensity， so as to provide references for early identification and targeted intervention for children with ADHD propensity. MethodsFrom July to August 2021， 25 children with ADHD propensity were screened as the ADHD propensity group， and 25 children matched for age， gender and grade were included as the normal group in an elementary school in Guangzhou. ADHD core symptoms were assessed by the Chinese version of the Swanson Nolan and Pelham， version IV-parent form for ADHD （SNAP-IV）， and behavioral problems were assessed by Questionnaire-Children with Difficulties （QCD） and Conners Parental Symptom Questionnaire （PSQ）. Spearman correlation analysis was used to examine the correlation between ADHD core symptoms and QCD and PSQ scores， and hierarchical linear regression analysis was used to explore the effect of ADHD core symptoms on behavioral problems. Results① The differences between the groups showed that both attention deficit and hyperactivity-impulsivity factor scores were higher in the ADHD propensity group than those in the normal group （t=7.771， 6.726， P<0.01）. ② Correlation analysis showed that the attention deficit factor score was negatively correlated with QCD total score （r=-0.440， P<0.05）， and positively correlated with the learning problem factor score of PSQ （r=0.457， P<0.05）. The score of hyperactivity-impulsivity was negatively correlated with score of anxiety factor in PSQ （r=-0.457， P<0.05）， and positively correlated with impulse-hyperactivity factor score （r=0.552， P<0.01）. ③ Hierarchical linear regression analysis showed that the attention deficit factor score negatively predicted the total score of QCD （B=-0.682， P<0.05， R²=0.468）. The hyperactivity-impulsivity factor score had a negative predictive effect on the anxiety factor score of PSQ （B=-0.048， P<0.05， R²=0.367）， and had a positive predictive effect on the impulsivity-hyperactivity factor score （B=0.077， P<0.01， R²=0.424）. ConclusionChildren with ADHD propensity have significant attention deficit symptoms， hyperactivity-impulsivity symptoms and behavioral problems， and the attention deficit may be the main cause of their daily behavioral problems， while hyperactivity-impulsivity may be the main cause of their impulsive-hyperactivity problems.
