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 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.
