The characteristics and rules of acupoint selection of acupuncture for trigeminal neuralgia were analyzed. By searching CNKI, VIP, WF, literature regarding acupuncture for trigeminal neuralgia from 1980 to 2013 was collected to establish an acupuncture prescription database. The data mining technology was applied to analyze the characteristics and rules of the acupoint selection. As a result, a total of 180 papers were included, involving 148 acupoints. It was found that the acupoints that had high frequency of selection included Hegu (LI 4), Xiaguan (ST 7), Fengchi (GB 20) and trigger points. The acupoints selected were distributed in 14 meridians, in which yangming meridian of hand-foot had a frequency of 41. 58%. The special acupoints including crossing points, yuan-primary points and five-shu points were widely used, accounting for 65. 9%. As for the branch of trigeminal nerve, the top-3 selected acupoints were Yangbai (GB 14), Yuyao (EX-HN 4), Cuanzhu (BL 2) in the first branch, Sibai (ST 2), Quanlian (SI 18), Yingxiang (LI 20) in the second branch, Jiache (ST 6), Xiaguan (ST 7), Dicang (ST 4) in the third branch. In conclusion, it is believed that the clinical treatment of trigeminal neural gia focuses on local acupoints in combination with nerve distribution-based acupoints and distal acupoints, also the special acupoints are emphasized.

Objective To study the cell vitality and ultra-structure of in vitro cultured fetus chondrocytes exposed to different doses of fluoride.Methods Primary chondrocytes were obtained from articular cartilage of the 24-27 weeks,aborted and dead fetuses.The third generation of primary cultured chondmcytes were exposed to concentrations of 0,10-2,5 × 10-3,10-3,10-4,10-5,10-6,10-7 and 10-8 mol/L fluoride for 24,48 and 72 h.Cell vitality was detected with Cell Counting Kit-8 (CCK-8) and ultra-structure of chondrocytes was observed by transmission electron microscope.Results The cell vitalities of chondrocytes exposed to doses of fluoride (10-2,5 ×10-3,10-3,10-4,10-5,10-6,10-7 and 10-8 moL/L) for 24,48 and 72 h were(15.04 ± 0.55)％,(62.53 ± 1.03)％,(100.34 ± 5.19)％,(111.40 ± 3.69)％,(121.47 + 6.09)％,(129.95 ± 4.96)％,(121.81 ± 4.97)％,(111.00 ± 1.63)％;(10.35 ± 0.64)％,(35.23 ± 2.41)％,(110.30 ± 2.07)％,(113.66 ± 6.98)％,(120.36 ± 6.23)％,(133.40 ± 5.80)％,(126.06 ± 5.40)％,(115.62 ± 7.33)％; (6.19 ± 0.16)％,(18.44 ± 0.21)％,(120.83 ± 4.93)％,(123.77 ± 4.82)％,(129.09 ± 5.21)％,(140.44 + 4.18)％,(131.99 ± 7.00)％,(124.10 ± 3.68)％,respectively.The cell vitalities of 10-2,5 × 10-3 mol/L fluoride groups were significantly lower than that of the control group (all P ＜ 0.05).The cell vitality of 10-2 mol/L group was significantly lower than that of the 5 × 10-3 mol/L group (P ＜ 0.05).Doses of fluoride (10-2,5 × 10-3 mol/L) could inhibit the cell vitality and promote the apoptosis of chondrocytes in vitro with increasing doses and prolonged time.The cell vitalities of 10-3,10-4,10-5,10-6,10-7,10-8 mol/L of fluoride groups were significantly higher than that of the control group (except the 24 h 10-3 mol/L,P ＜ 0.05).Between 10-4 and 10-3 mol/L groups(the vitalities of 48 h and 72 h were higher,but not significantly); 10-5 and 10-4 mol/L groups (the vitality of 72 h was higher,but not significantly); 10-6 and 10-5 mol/L groups,the cell vitalities were significantly higher than that of the control group(all P ＜ 0.05).Between 10-7 and 10-6 mol/L groups,10-8 and 10-7 mol/L groups (the vitality of 72 h was lower,but not significantly),the cell vitalities were significantly lower than that of the control group(all P ＜ 0.05).Doses of fluoride(10-3-10-8 mol/L) could promote the cell vitality of chondrocytes in vitro with prolonged time.The optimal concentration for the promotion was 10-6 mol/L.The cells of the control group were characterized as regular morphology,the abnormal surface microvillis,abundant cytoplasm and mitochondrial,abundant and slightly expanded rough endoplasmic reticulums and low electron-dense materials.The cells of 10-6 mol/L fluoride group had the following changes,increased and swell mitochondrial,hypertrophy and expanded rough endoplasmic reticulums.The cells of 5 × 10-3 mol/L fluoride group had the following changes,decreased microvillis,invaginated cell membrane,pyknosis and apoptotic body.Conclusion Doses of fluoride (10-3-10-8 mol/L) can promote the proliferation of human chondrocytes cultured in vitro.Doses of fluoride (10-2,5 × 10-3 mol/L) can promote the apoptosis of human chondrocytes cultured in vitro.

OBJECTIVETo investigate, from cytoprotein and molecular levels, the action mechanism of astragalus injection (ASI) on the signal conduction of human renal tubular cells (HK-2) injury induced by neonatal postasphyxial-serum (NPS), whether it is through activating the nuclear factor kappaB (NF-kappaB) signaling pathway.

METHODSTaking HK-2 as the target cell and the 20% NPS as the attacking factor, the experiment was conducted by dividing the target cells into two groups before attacking, the blank control group and the ASI pretreated group. The nuclear translocation of NF-kappaB was detected by confocal microscopy with indirect immunofluorescence stain, and the amount of NF-kappaB inhibitor subunit (I-kappaBalpha) was detected by Western blot before attacking. The detections were repeated at various time points in the experiment, i.e., 15 min, 1 h and 2 h after attacking, respectively.

RESULTSBefore attacking, the nuclear translocation of NF-kappaB and the amount of I-kappaBalpha were not different in the two groups. But the former increased and the latter decreased significantly in the ASI group at all the time points after attacking with the topmost changes presented at 1 h after attacking, and significantly different to those in the control group at corresponding time

CONCLUSIONASI pretreatment could inhibit the activation of NF-kappaB induced by postasphyxial-serum.

Induced pluripotent stem cells (iPSCs) can be propagated indefinitely, while maintaining the capacity to differentiate into all cell types in the body except for the extra-embryonic tissues. This iPSC technology not only represents a new way to use individual-specific stem cells for regenerative medicine but also constitutes a novel method to obtain large numbers of disease-specific cells for biomedical research. However, the low efficiency of reprogramming and genomic integration of oncogenes and viral vectors limit the potential application of iPSCs. Chemical-induced reprogramming offers a novel approach to generating iPSCs. In this study, a new combination of small-molecule compounds (SMs) (sodium butyrate, A-83-01, CHIR99021, Y-27632) under conditions of transient folate deprivation was used to generate iPSC. It was found that transient folate deprivation combined with SMs was sufficient to permit reprogramming from mouse embryonic fibroblasts (MEFs) in the presence of transcription factors, Oct4 and Klf4, within 25 days, replacing Sox2 and c-Myc, and accelerated the generation of mouse iPSCs. The resulting cell lines resembled mouse embryonic stem (ES) cells with respect to proliferation rate, morphology, pluripotency-associated markers and gene expressions. Deprivation of folic acid, combined with treating MEFs with SMs, can improve the inducing efficiency of iPSCs and reduce their carcinogenicity and the use of exogenous reprogramming factors.
