ABSTRACT
The paper introduces professor WU Xu 's experience of sequential therapy for peripheral facial paralysis. The sequential therapy refers to a staging treatment, but not rigidly adheres to it. With this therapy, the acupuncture- moxibustion regimen is modified flexibly in line with the specific symptoms of illness. At the acute phase of peripheral facial paralysis, warm acupuncture at Wangu (GB 12) is predominated and electroacupuncture is not recommended at the acupoints on the face. At the recovery phase, warm acupuncture at Zusanli (ST 36) is the main therapy and electroacupuncture is applied to the acupoints on the face appropriately. Besides, for the intractable case, the tapping technique with plum-blossom needle or skin needle should be combined and exerted in the local affected region. At the sequelae phase, in order to shorten the duration of illness, depending on the different types of facial paralysis, i.e. stiffness type, spasmodic type and flaccid type, the corresponding needling techniques are provided, i.e. bloodletting and moxibustion, strong stimulation with contralateral acupuncture and the technique for promoting the governor vessel and warming up yang.

With the development of nanomaterials, fluorescent nanoprobes have attracted enormous attention in the fields of chemical sensing, optical materials, and biological detection. In this paper, the advantages of "off-on" fluorescent nanoprobes in disease detection, such as high sensitivity and short response time, are attentively highlighted. The characteristics, sensing mechanisms, and classifications of disease-related target substances, along with applications of these nanoprobes in cancer diagnosis and therapy are summarized systematically. In addition, the prospects of "off-on" fluorescent nanoprobe in disease detection are predicted. In this review, we presented information from all the papers published in the last 5 years discussing "off-on" fluorescent nanoprobes. This review was written in the hopes of being useful to researchers who are interested in further developing fluorescent nanoprobes. The characteristics of these nanoprobes are explained systematically, and data references and supports for biological analysis, clinical drug improvement, and disease detection have been provided appropriately.

OBJECTIVE: To compare the therapeutic effect of thunder-fire moxibustion combined with vibration training and simple vibration training on low back pain of primary osteoporosis by Young's modulus of ultrasonic wave, and seek an objective evaluating method. METHODS: A total of 60 patients were randomized into an observation group and a control group, 30 cases in each one. The patients in the two groups were treated with vibration training using whole body vibration treatment bed. In the observation group, thunder-fire moxibustion was applied at Yaoyangguan (GV 3), Mingmen (GV 4), Ganshu (BL 18), Shenshu (BL 23) and Dachangshu (BL 25). The treatment was given once every other day, 3 times a week for 4 weeks. The visual analogue score (VAS), real-time shear wave elastography (RTSWE) and medical outcomes study 36-item short-form hearth survey (SF-36) were used to evaluate pain intensity, multifidus muscle tone (Young's modulus) and quality of life before treatment, after 4-week treatment and 1 month after treatment. RESULTS: Compared before treatment, the VAS scores, Young's modulus of multifidus muscle and 5 dimensions of SF-36 (physical condition, body pain, general health, social function and mental health) after 4-week treatment and 1 month after treatment were significantly improved in the two groups (all P<0.05), the physiological role in the observation group after 4-week treatment and 1 month after treatment were improved (both P<0.05). In the observation group, the VAS scores, Young's modulus of multifidus muscle and 3 dimensions of SF-36 (physiological role, body pain and general health) after 4-week treatment and 1 month after treatment were superior to the control group (all P<0.05). CONCLUSION: The therapeutic effect of thunder-fire moxibustion combined with vibration training is superior to simple vibration training in relieving low back pain intensity and multifidus muscle tone, and improving quality of life for primary osteoporosis. RTSWE technique can be an objective examination method to evaluate pain.

BACKGROUND/AIMS: We aimed to investigate the correlation between a disintegrin and metalloprotease with thrombospondin motif 2 (ADAMTS-2) and transforming growth factor-ß1 (TGF-ß1) in clinical human cirrhotic tissues. METHODS: The liver tissues of 24 patients (16 cases with cirrhotic portal hypertension as the cirrhosis group and eight cases with healthy livers as the normal group) were collected. Immunohistochemistry and Western blots were performed to evaluate the protein expression levels of ADAMTS-2 and TGF-ß1. Western blots for other key mediators of cirrhotic progression, including SMAD2, SMAD3, TGF-ß receptor II (TGFßRII), matrix metalloproteinases 2 (MMP2), and tissue inhibitor of matrix metalloproteinases 2 (TIMP2), were also performed. RESULTS: Cirrhotic tissues showed higher percentages of collagen. The protein expression levels of ADAMTS-2 and TGF-ß1 were significantly higher in the cirrhotic group as compared to the matched normal group (p<0.05), and there was a positive correlation between these two proteins (r=0.862, p<0.01). The protein expressions of MMP2, TIMP2, and TGFßRII, as well as the phosphorylated forms of SMAD2 and SMAD3, were significant higher in the cirrhotic group (p<0.01 or p<0.05). CONCLUSIONS: These findings suggested that ADAMTS-2 and TGF-ß1 may play important roles in the pathogenesis of human cirrhosis; specifically, TGF-ß1 may induce the expression of ADAMTS-2 through the TGFß/SMAD pathway.
ABSTRACT
It is known that estrogen promotes the proliferation of breast cancer cells. Agonists to P2Y(2) receptors promote or suppress proliferation in different cancers. In the present study, the methods of methylthiazoltetrazolium (MTT) assay, real-time RT-PCR, Western blot and fluorescent calcium imaging analysis were used to investigate whether P2Y(2) receptors play a role in the effects of estrogen on the breast cancer cell lines, MCF-7 and MDA-MB-231. We found that P2Y(2) receptors were expressed in both the estrogen receptor alpha (ER(α))-positive breast cancer cell line MCF-7 and the ER(α)-negative breast cancer cell line MDA-MB-231. 17ß-Estradiol (17ß-E(2)) (1 pM to 1000 nM) promoted proliferation of MCF-7 cells, which was blocked by the ER antagonist ICI 182,780 (1 µM) and the ER(α) antagonist methyl-piperidino-pyrazole (MPP, 50 µM), but not by the ER(ß) antagonist 4-[2-phenyl-5,7-bis(trifluoromethyl)pyrazolo[1,5-a]pyrimidin-3-yl]phenol (PHTPP, 50 µM) or ER(ß) small interfering RNA. The P2Y(2) and P2Y(4) receptor agonist UTP (10-100 µM) suppressed the viability of breast cancer cells in both MCF-7 and MDA-MB-231 cells. The effect was blocked by suramin (10-100 µM), known to be an effective antagonist against P2Y(2), but not P2Y(4), receptor-mediated responses. 17ß-E(2) played a more positive role in promoting proliferation in MCF-7 cells when suramin blocked the functional P2Y(2) receptors. 17ß-E(2) (0.1-1000 nM) downregulated the expression of P2Y(2) receptors in terms of both mRNA and protein levels in MCF-7 cells. The effect was blocked by ICI 182,780 and MPP, but not PHTPP or ER(ß) small interfering RNA. 17ß-E(2) did not affect the expression of P2Y(2) receptors in MDA-MB-231. UTP (10-100 µM) led to a sharp increase in intracellular Ca(2+) in MCF-7 cells. Pre-incubation with 17ß-E(2) (0.1 µM) attenuated UTP-induced [Ca(2+)](i), which was blocked by ICI182,780 and MPP, but not PHTPP. It is suggested that estrogen, via ER(α) receptors, promotes proliferation of breast cancer cells by down-regulating P2Y(2) receptor expression and attenuating P2Y(2)-induced increase of [Ca(2+)](i).
