OBJECTIVE: To evaluate the effectiveness in treatment of chronic neck pain with the direct moxibustion of small moxa cone and explore the dose-effect relationship in treatment of chronic neck pain with different small moxa cones. METHODS: A total of 120 patients with chronic neck pain were randomized into a 3-moxa-cone group, a 5-moxa-cone group, a 7-moxa-cone group and a sham-moxibustion group, 30 cases in each one. Fengchi (GB 20), Tianzhu (BL 10), Jingbailao (EX-HN 15), Jianzhongshu (SI 15) and Jianjing (GB 21) were selected in each of the groups. The direct moxibustion with 3, 5 and 7 moxa cones as well as the sham-moxibustion therapy were provided successively in each of the above groups. In the sham-moxibustion group, the lower 1/3 section of moxa cone (about 1.5 mm in length) was soaked in oil before used in treatment. In each group, the treatment was given twice a week, for 10 treatments totally. Separately, before treatment, after treatment and in 1-month follow-up, the scores of the Northwick Park neck pain questionnaire (NPQ), the scores of McGill pain questionnaire (MPQ) and the local pressure pain threshold (PPT) were observed in each group. After treatment and in 1-month follow-up, the therapeutic effects were evaluated in each group. RESULTS: After treatment and in 1-month follow-up, NPQ scores and MPQ scores in the 3-moxa-cone group, the 5-moxa-cone group and the 7-moxa-cone group were reduced as compared with those before treatment separately (all <0.01), PPT values were increased as compared with those before treatment (all <0.01). But the differences were not statistically significant in the sham-moxibustion group as compared with those before treatment (all >0.05). After treatment and in 1-month follow-up, NPQ scores and MPQ scores in the 3-moxa-cone group, the 5-moxa-cone group and the 7-moxa-cone group were lower as compared with the sham-moxibustion group separately (all <0.05), PPT values were higher as compared with the sham-moxibustion group (all <0.05). After treatment, the NPQ score and MPQ score in the 7-moxa-cone group were lower than the 3-moxa-cone group and PPT values was higher than the 3-moxa-cone group (all <0.05). After treatment and in 1-month follow-up, the therapeutic effects in the 3-moxa-cone group, the 5-moxa-cone group and the 7-moxa-cone group were better than the sham-moxibustion group separately (all <0.05). But, the therapeutic effects were not significantly different in comparison among the moxibusiton groups (>0.05). CONCLUSION The direct moxibustion therapy with different small-moxa-cones effectively relieves chronic neck pain. There is a trend of improvement of the therapeutic effects with increase of the numbers of moxa cones.

OBJECTIVE: To investigate the effect of SARI overexpression on the proliferation and apoptosis of core binding factor leukemia (CBFL) cells and explore the potential molecular mechanisms. METHODS: C-KIT N822K mutation status in Kasumi-1 cell line was detected by exon 17 sequencing. Then the SARI lentiviral vector (pGC-FU-SARI) was constructed, meanwhile Kasumi-1 cells were transfected with the SARI lentiviral vector. Quantitative PCR and Western blot were employed to identify efficacy of SARI overexpression after the transfection of cells. Cells were divided into three groups, including the cells infected with pGC-FU-SARI (OE group), the cells infected with pGC-FU-GFP (NC group) and the untreated cells (blank control group). Cell proliferative activity was tested by MTT assay, cell apoptosis was measured by flow cytometry (FCM) and the expression of apoptosis-related proteins: BCL-2,BAX,Cyto C,Caspase 9,Caspase 3,cleaved-Caspase 3,PARP and cleaved-PARP as well as PI3K/Akt pathway proteins: PI3K（p85）,p-PI3K（p85）,Akt and p-Akt were detected by Western blot. RESULTS: The Kasumi-1 cells were detected to bear c-KIT N822K (T>A) mutation. The Kasumi-1 cells with SARI was overexpression were construeted successfully. Compared with NC group, the cell proliferation was decreased and cell apoptosis was increased; BCL-2 expression was reduced, BAX expression was enharued; cyto C expression appeared; the expression of Caspase 9 and Caspase 3 was down-regulated, the expression of cleaved Caspase 3 was up-regulated; the PARP expression was decreased, cleaved PARP expression was increased; the phosphorylation level of PI3K/Akt pathway proteins: p-PI3K/PI3K, p-Akt/Akt was down-regulated in OE group (P<0.05). CONCLUSION SARI gene may suppress the proliferation of CBFL cells, and induce their apoptosis through the mitochondrial pathway, which may be related with the inhibition of PI3K/Akt pathway.

This study was to investigate the mechanism of safflower yellow injection for regulating inflammatory response against myocardial ischemia-reperfusion injury( MIRI) in rats. Male Wistar rats were randomly divided into sham operation group,model group,Hebeishuang group,safflower yellow injection high,medium and low dose groups. MIRI model was established by ligating left anterior descending coronary artery. Myocardial histopathological changes were observed by HE staining; myocardial infarct size was detected by TTC staining; content and changes of tumor necrosis factor-α( TNF-α) and interleukin-6( IL-6),serum creatine kinase( CK),aspartate aminotransferase( AST),and lactate dehydrogenase( LDH) were detected by biochemical method or enzyme-linked immunosorbent assay( ELISA). Western blot assay was used to detect the protein expression of Toll-like receptor 4( TLR4) and nuclear factor-κB( NF-κB p65) in myocardial tissues. The results showed that as compared with the sham operation group,the myocardial arrangement of the model group was disordered,with severe edemain the interstitial,significantly increased area of myocardial infarction,increased activities of AST,CK and LDH in serum,and significantly increased contents of TNF-α and IL-6; the expression levels of TLR4 and NF-κB( p65) protein in myocardial tissues were also increased. As compared with the model group,the myocardial tissues were arranged neatlyin the Hebeishuang group and safflower yellow injection high,medium and low dose groups; the edema was significantly reduced; the myocardial infarct size was significantly reduced; the serum AST,CK,LDH activity and TNF-α,IL-6 levels were significantly decreased,and the expression levels of TLR4 and NF-κB( p65) protein in myocardial tissues were decreased. As compared with the Hebeishuang group,the myocardial infarct size was larger in the safflower yellow injection high,medium and low dose groups; the activities of AST,CK and LDH in serum and the contents of TNF-α and IL-6 in serum were higher,but there was no statistically significant difference in the expression levels of TLR4 and NF-κB( p65) protein in tissues. It is suggested that safflower yellow injection has a significant anti-MIRI effect,and its mechanism may be related to the regulation of TLR-NF-κB pathway to inhibit inflammatory response.

OBJECTIVE: To study the clinical characteristics, drug sensitivity of isolated strains, and risk factors of drug resistance in children with invasive pneumococcal disease (IPD). METHODS: The clinical characteristics and drug sensitivity of the isolated strains of 246 hospitalized children with IPD in nine grade A tertiary children's hospitals from January 2016 to June 2018 were analyzed. RESULTS: Of the 246 children with IPD, there were 122 males and 124 females. Their ages ranged from 1 day to 14 years, and among them, 68 (27.6%) patients were less than 1 year old, 54 (22.0%) patients were 1 to 2 years old, 97 (39.4%) patients were 2 to 5 years old, and 27 (11.0%) patients were 5 to 14 years old. Pneumonia with sepsis was the most common infection type (58.5%, 144/246), followed by bloodstream infection without focus (19.9%, 49/246) and meningitis (15.0%, 37/246). Forty-nine (19.9%) patients had underlying diseases, and 160 (65.0%) had various risk factors for drug resistance. The isolated Streptococcus pneumoniae strains were 100% sensitive to vancomycin, linezolid, moxifloxacin, and levofloxacin, 90% sensitive to ertapenem, ofloxacin, and ceftriaxone, but had a low sensitivity to erythromycin (4.2%), clindamycin (7.9%), and tetracycline (6.3%). CONCLUSIONS IPD is more common in children under 5 years old, especially in those under 2 years old. Some children with IPD have underlying diseases, and most of the patients have various risk factors for drug resistance. Pneumonia with sepsis is the most common infection type. The isolated Streptococcus pneumoniae strains are highly sensitive to vancomycin, linezolid, moxifloxacin, levofloxacin, ertapenem, and ceftriaxone in children with IPD.

AIM:To investigate the effects of Chinese traditional medicine-selected recipe Q0409 on the ability of learning and memory in SAM-P/8 mice. METHODS:Total 91 mice (4-month-old SAM-P/8 mice, SAM-R/1 mice and Kunming mice) were used in the study, in which the male and female animals were labeled separately. According to the performance of Morris water maze test, the mice were divided into 5 groups randomly. The mice were fed with different drugs or distilled water for 60 d (from 4 months to 6 months). The mice were fed with the drugs from 61 d to 65 d, and 1 h later each time, the Morris water maze test was carried out. After this Morris test were finished at 65 d, the mice were killed immediately and their hippocampal tissues were isolated. Half of the hippocampal tissues were added with precooled normal saline and made into 10% (g/mL) homogenate for detecting the protein content and acetyl cholinesterase (AChE) activity. The other half was fixed with 4% paraformaldehyde and embedded with paraffin for immunohistochemical staining of amyloid β-protein (Aβ). RESULTS:Compared with model group, the results of navigation training and spatial probe training in Morris water maze test were significantly improved (P<0.05), and the activity of AChE in the hippocampal ho-mogenate was significantly decreased (P<0.05) in Q0409 treatment group. No difference in Q0409 group was observed compared with control group and positive drug (huperzine A) group. Immunohistochemical staining showed no typical "se-nile plaques" in the male mice of Q0409 group, while there was shallower and smaller brown staining in the hippocampus of the female mice of Q0409 group. The positive area of Aβ deposition decreased in the CA1 area of hippocampal tissues in Q0409 group. These results were similar to those in positive drug group. CONCLUSION:Q0409 improves the ability of learning and memory in SAM-P/8 mice, which is related to the inhibition of AChE activity and the reduction of Aβ protein deposition in the hippocampus. The effects is similar to those of huperzine A.
