The aim of this study was to investigate the in vitro effect of interleukin-24 (IL-24) on apoptosis of bone marrow mononuclear cells (BMMNC) in children with acute leukemia. Every group of acute lymphocytic leukemia (ALL) and acute myeloid leukemia (ANLL) had 20 children who did not receive any therapy. The bone marrow was taken from patients and controls, the MNC were isolated from bone marrow, DNA was detected by glucose electrophoresis. Apoptosis of BMMNC was assayed by flow cytometry with propidium iodine staining. RT-PCR was used to detect the expression level of bcl-2, caspase-3 mRNA, and to analyze the effect of IL-24 on them. The results showed that the IL-24 induced apoptosis of BMMNC in children with acute leukemia. After acute leukemia BMMNC were exposed to IL-24 for 48 hours, DNA ladder fragment appeared, and the apoptotic rate of the group treated with IL-24 of 50 ng/ml was obviously higher than that of the control group (0 ng/ml). IL-24 decreased the bcl-2 mRNA expression level, enhanced caspase-3 mRNA expression level of BMMNC from AL patients. It is concluded that the IL-24 can induce apoptosis of AL BMMNC in vitro, which may be due to decreasing of bcl-2 mRNA level and enhancing of caspase-3 mRNA level.

Objective To explore the clinical effects of Yikou mouth-wash liquid on oral lavage of coma patients with tracheotomy.Methods 120 coma patients with tracheotomy accompanying with oral complications were randomly divided into observation group ( n =60) and control group (n =60).The observation group was administered with Yikou mouth-wash liquid to lavage oral cavity,while the control group was used with isotonic saline solution.The effects of both groups with respect to oral stench,swollen bleeding gums and oral ulcers were compared.Results The observation group got a higher effective rate than the control group regarding oral stench ( x2 =18.950,P ＜ 0.05 ),swollen bleeding gums ( x2 =17.635,P ＜ 0.05 ) and oral ulcers ( x2 =9.000,P ＜ 0.05 ).Conclusions Yikou mouth-wash liquid is superior to isotonic saline solution with respect to clinical effects while applied to coma patients with tracheotomy,so it has clinical significance to some extent.

Objective To observe the effects of Xingbi Wenmin Gel on serum levels of IL-4, TGF-β1 and nasal mucosa eosinophils (EOS) in allergic rhinitis (AR) rats; To discuss its mechanism of action. Methods Intraperitoneal injection of egg albumin and aluminum hydroxide based sensitized to ovalbumin challenge 2％ local AR model was established successfully. The experimental rats were randomly divided into normal group, model group, positive control group, and Xingbi Gel low-, medium-, and high-dosage groups. Each medication group was given relevant medicine for intervention. The rat symptom scores in each group were compared, and serum IL-4, TGF-β1, and nasal mucosa EOS counts were detected. Results Compared with the normal group, the serum levels of IL-4 and TGF-β1 in model group increased significantly (P<0.01), and the nasal mucosa EOS counts increased significantly (P<0.05). Compared with model group, the serum levels of IL-4 and TGF-β1 in Xingbi Gel medium-dosage group and positive control group decreased significantly (P<0.01), and the nasal mucosa EOS counts decreased significantly (P<0.05). Conclusion Xingbi Wenmin Gel may be effective through down-regulation of IL-4, TGF-β1 levels of inflammatory factors, and reduction of EOS infiltration in nasal mucosa.

OBJECTIVETo evaluate the quality and consistency of recommendations in the clinical practice guidelines (CPGs) for hypertension in Chinese medicine (CM).

METHODSCM CPGs were identified from 5 electronic databases and hand searches through related handbooks published from January 1990 to December 2013. Three reviewers independently appraised the CPGs based on the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument, and compared the CPGs' recommendations on CM syndrome pattern classification and treatment.

RESULTSFive CM CPGs for hypertension were included. The quality score of the evidence-based (EB) guideline was higher than those of the consensus-based with no explicit consideration of evidence-based (CB-EB) and the consensus-based (CB) guidelines. Three out of five patterns in the CPGs were recommended by the EB guideline. Tianma Gouteng Formula () in the EB guideline was recommended mostly for hypertension patients with pattern of ascendant hyperactivity of Gan (Liver)-yang and pattern of yin deficiency with yang hyperactivity in the CPGs. Acupuncture and massage were recommended for Grade I and Grade II hypertension with severe symptoms weakening the quality of life in the EB guideline. For Grade I and Grade II hypertension, CM could be used alone, while for Grade III hypertension, they should be used in combination with Western medicines.

CONCLUSIONThe quality of EB guideline was higher than those of CB and CB-EB CPGs in CM for hypertension and CM should be prescribed alone or combined with Western medicines based on the grade of hypertension.

OBJECTIVE: To explore the distribution characteristics of main antigen gene frequencies of Duffy,Diego,Kidd,Dombrock,MNS,Lutheran,Kell,Colton,Scianna,Yt,Knops and Indian in red blood cell blood group system of Li nationality in Hainan Province. METHODS: Antigens in twelve rare blood group systems of 214 Li people in Hainan Province were genotyped and analyzed by polymerase chain reaction-sequence specific primers (PCR-SSP). RESULTS: The gene frequency of antigens in twelve rare blood group systems of 214 Li people in Hainan Province including: the gene frequency of Duffy blood group system: fy CONCLUSION The genetic distribution and genetic status in twelve rare blood group systems of Li nationality in Hainan Province are relatively stable. The gene distribution of Duffy, Diego, Kidd, Drombrock, MNS and Lutheran blood group systems are polymorphic and show unique distribution characteristics compared with other regions and different nationalities. The gene frequency distribution of Kell、Colton、Scianna、Yt、Knops、Indian blood group systems are monomorphic.

Objective To investigate the distribution and antimicrobial resistance profiles of the common pathogens isolated from urine from 2015 to 2021 in the CHINET Antimicrobial Resistance Surveillance Program.Methods The bacterial strains were isolated from urine and identified routinely in 51 hospitals across China in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Antimicrobial susceptibility was determined by Kirby-Bauer method,automatic microbiological analysis system and E-test according to the unified protocol.Results A total of 261 893 nonduplicate strains were isolated from urine specimen from 2015 to 2021,of which gram-positive bacteria accounted for 23.8％(62 219/261 893),and gram-negative bacteria 76.2％(199 674/261 893).The most common species were E.coli(46.7％),E.faecium(10.4％),K.pneumoniae(9.8％),E.faecalis(8.7％),P.mirabilis(3.5％),P.aeruginosa(3.4％),SS.agalactiae(2.6％),and E.cloacae(2.1％).The strains were more frequently isolated from inpatients versus outpatients and emergency patients,from females versus males,and from adults versus children.The prevalence of ESBLs-producing strains in E.coli,K.pneumoniae and P.mirabilis was 53.2％,52.8％and 37.0％,respectively.The prevalence of carbapenem-resistant strains in E.coli,K.pneumoniae,P.aeruginosa and A.baumannii was 1.7％,18.5％,16.4％,and 40.3％,respectively.Lower than 10％of the E.faecalis isolates were resistant to ampicillin,nitrofurantoin,linezolid,vancomycin,teicoplanin and fosfomycin.More than 90％of the E.faecium isolates were ressitant to ampicillin,levofloxacin and erythromycin.The percentage of strains resistant to vancomycin,linezolid or teicoplanin was＜2％.The E.coli,K.pneumoniae,P.aeruginosa and A.baumannii strains isolated from ICU inpatients showed significantly higher resistance rates than the corresponding strains isolated from outpatients and non-ICU inpatients.Conclusions E.coli,Enterococcus and K.pneumoniae are the most common pathogens in urinary tract infection.The bacterial species and antimicrobial resistance of urinary isolates vary with different populations.More attention should be paid to antimicrobial resistance surveillance and reduce the irrational use of antimicrobial agents.
