After intervention, the self-care ability score and life quality score of observation group were significantly higher than that in control group (P < 0.01). Conclusion The personalized intervention can reduce the complications, significantly improve the patients' life quality score and self-care ability, and effectively alleviate the negative situation, improve the patients intervention satisfaction, with a higher development value, it is worth of clinical promoting.

OBJECTIVETo evaluate the effects and safety of penetrating needling on head acupoints for perennial allergic rhinitis (PAR).

METHODSEighty-one cases of PAR were randomly divided into an acupuncture group (41 cases) and a medication group (40 cases). Penetrating needling at head acupoints was adopted from Baihui (GV 20) to Qianding (GV 21) and from Shangxing (GV 23) to Shenting (GV 24) in the acupuncture group. A to tal 4-week treatment was given to the patients with 3 treatments a week. Loratadine tablet and azelastine hydrochloride nasal spray were given to the medication group continuously for 12 days. A follow-up was carried out 3 months after the treatment. The efficacy, symptom score and physical sign score, and side accidents were observed in both groups.

RESULTSThe total effective rate was 95.1% (39/41) in the acupuncture group, which was better than 82.5% (33/40) in the medication group (P < 0.05). The total scores of clinical symptoms and each partial scores after the treatment, and total scores of clinical symptoms in follow-up were obviously decreased in both groups (all P < 0.01), the nasal obstruction score and the total scores of clinical symptoms in the acupuncture group were better than those in the medication group (P < 0.01, P < 0.05). Obvious side-effect had not been found during the treatment.

CONCLUSIONPenetrating needling at head acupoints is a safe therapy for patients with PAR, and favorable effects can be found in both short term and long term.

BACKGROUND: Platelet-rich plasma (PRP) and naringin can both promote proliferation and induce osteogenic differentiation of mesenchymal stem cells. However, their combined use is rarely reported. OBJECTIVE: To observe the effect of PRP combined with naringin on the osteogenic differentiation of human bone marrow mesenchymal stem cells(hBMSCs)in vitro. METHODS: BMSCs at passage 3 were divided into four groups: (1) blank control group, cells were cultured in α-MEM; (2) PRP group, cells were cultured in α-MEM containing PRP; (3) naringin group, cells were cultured in α-MEM containing naringin; and (4) combined group, cells were cultured in α-MEM containing PRP and naringin. The contents of used PRP and naringin were 12.5% and 50 μg/L respectively. Cell proliferation was detected by MTT assay. Expression of related genes in hBMSCs was detected by RT-PCR. Alkaline phosphatase staining, collagen type I immunohistochemical staining, and alizarin red staining were used to analyze the osteogenic differentiation of hBMSCs. RESULTS AND CONCLUSION: The proliferation of hBMSCs was increased in each group, especially in the combined group. Cells in all the groups except the blank control group were positive for alkaline phosphatase staining, collagen type I immunohistochemical staining, and alizarin red staining, and the positive effect was more obvious in the combined group. However, negative or weakly positive response was found in the blank control group. At 7 and 14 days, the expression of alkaline phosphatase and collagen type I was significantly higher in the PRP, naringin and combined groups than the blank control group (P < 0.05); at 14 days, the expression of alkaline phosphatase and collagen type I was significantly higher in the combined group than the PRP and naringin groups (P < 0.05). To conclude, PRP combined with naringin can promote the proliferation of hBMSCs and induce the osteogenic differentiation of hBMSCs. Moreover, there is a synergistic effect between PRP and naringin.

OBJECTIVETo prepare monoclonal antibodies (mAbs) against enoyl-CoA hydratase 1 (ECH1).

METHODSNormal human liver tissues were homogenized, and the mitochondria were isolated by differential centrifugation. The total mitochondrial proteins were used to immunize BALB/c mice to prepare mAbs by routine hybridoma technique. The mAbs were characterized by ELISA, Western blotting and immunohistochemistry. The specificity of the antibody was identified by mass spectrometry (MS) following immunoprecipitation (IP) and confirmed by Uni-ZAP expression library screening.

RESULTSOne clone of the hybridoma BGB095 secreting specific mAb against ECH1 was obtained. The mAb was identified to belong to Ig subclass IgG1 and could be used in ELISA, Western blotting, immunohistochemistry, and immunoprecipitation.

CONCLUSIONA hybridoma cell line stably secreting specific mAb against ECH1 has been established. The specific mAb against ECH1 can be of great value for functional and distribution studies of ECH1.

OBJECTIVETo study possible impairment mechanisms of learning and memory abilities from unsaturated fatty acids in hippocampus of mice exposed to lead.

METHODSForty-eight healthy mice were divided into 4 groups: low dose (0.625 g/L), middle dose (1.250 g/L) and high dose (2.500 g/L) of lead solution in diet and control group (distilled water). The mice in treatment groups were fed with lead solution every day while the mice in control group were fed with distilled water for 50 days. After learning and memory abilities were measured, the mice were killed and contents of oleic acid (C18:1), linoleic acid (C18:2), linolenic acid (C18:3), arachidonic acid (AA,C20:4), eicosapentaenoic acid (EPA,C20:5) and docosahexaenoic acid (DHA, C22:6 ) in hippocampus of mice were determined by high performance liquid chromatography (HPLC).

RESULTS(1) In the four training days, the mice treated with lead in the middle dose group and high dose group significantly increased the escape latencies compared with the mice treated with distilled water (P<0.05), and on the 4th day, the low dosage mice's escape latencies were delayed (P<0.05). The escape latencies of the 1st, 2nd, 3rd and 4th day had significantly positive linear relation with lead dose. Their relative coefficient in turn is r=0.973, 0.985, 0.929 and 0.936, indicating that lead harmed spatial memory of mice in Morris water maze (MWM). (2) The contents of C18:2 and AA were obviously enhanced in hippocampus of middle and high dosage (P<0.05); while there was evident decrease in the contents of C18:3, EPA and DHA (P<0.05); the content of C18:1 was decreased significantly in high dosage group (P<0.01). The mice's escape latencies had significantly negative linear relation with contents of C18:1, C18:3, EPA and DHA, while there was positive linear relation significantly with contents of C18:2 and AA. Their relative coefficient in turn was r=-0.901, -0.914, -0.893, -0.855, 0.936, 0.727.

CONCLUSIONLead interferes with the metabolism of hippocampus fatty acids and affects membrane function in hippocampus of mice, which might contribute to change of the synthesis, metabolism and release of central neurotransmitter and decrease of the learning and memory abilities.
