Exploring the mechanism of Chaihujia Longgu Muli decoction in the treatment of epilepsy in rats based on the RhoA/ROCK signaling pathway.

BACKGROUND: The Chinese herbal formula Chaihujia Longgu Muli Decoction (CD) has a good antiepileptic effect, but its mechanisms remain unclear. Therefore, in this study we explored the molecular mechanisms of CD against epilepsy. METHODS: Twelve-day-old SD rats were randomly divided into a normal group, model group, valproic acid group, and CD high, medium, and low groups. Except for the normal group, the other groups were given an intraperitoneal injection of pentylenetetrazol (PTZ) to establish epilepsy models, and the Racine score was applied for model judgment. After 14 consecutive days of dosing, the Morris water maze test was performed. Then, hippocampal Nissl staining and immunofluorescence staining were performed, and synaptic ultrastructure was observed by transmission electron microscopy (TEM). RhoA/ROCK signaling pathway proteins were detected. RESULTS: In PTZ model rats, the passing times were reduced, and the escape latency was prolonged in the Morris water maze test. Nissl staining showed that some hippocampal neurons swelled and ruptured, Nissl bodies in the cytoplasm were significantly reduced, and neurons were lost. Immunofluorescence detection revealed that the expression of PSD95 and SYP was significantly reduced. Electron microscopy results revealed that the number of synapses in hippocampal neurons was significantly reduced and the postsynaptic membrane length was significantly reduced. Western blot analysis showed that the RhoA/ROCK signaling pathway was activated, while SYP, SPD95, and PTEN expression was significantly decreased. After treatment with CD, neurobehavioral abnormalities and neuronal damage caused by epileptic seizures were improved. CONCLUSION: CD exerted an antiepileptic effect by inhibiting the activation of the RhoA/ROCK signaling pathway.

Systematic review of clinical trials of acupuncture-related therapies for primary dysmenorrhea.

BACKGROUND: Acupuncture-related therapies might be an effective intervention for primary dysmenorrhea. OBJECTIVE: To evaluate the effects of acupuncture-related therapies for treating primary dysmenorrhea. SEARCH STRATEGY: A specified literature search was performed of the Cochrane Library, MEDLINE, EMBASE, CNKI, and CBM databases. SELECTION CRITERIA: All clinical controlled trials pertaining to acupuncture-related therapies for primary dysmenorrhea were included, and the quality of the trials was assessed. DATA COLLECTION AND ANALYSIS: Two independent reviewers were responsible for data extraction and assessment. The original data of each trial were analyzed with software (Revman 4.2), but a meta-analysis could not be carried out because of the heterogeneity of the trials. MAIN RESULTS: Thirty randomized controlled trails (RCTs) and two controlled clinical trials (CCTs) were identified. Most of the trials were of low methodologic quality (six trials were Grade B and 26 trials were Grade C). Data analysis indicated that there were conflicting results regarding whether acupuncture-related therapies were more effective than control treatments. However, there was a small, methodologic sound trial of acupuncture which suggested that acupuncture was more effective than control groups (placebo acupuncture: WMD=-0.57 and 95% CI=-0.76-0.38; standard control: WMD=-.19 and 95% CI=-0.37-0.01; visitation control: WMD=-1.04 and 95% CI=-1.28-0.80). CONCLUSIONS: Because of low methodologic quality and small sample size, there is no convincing evidence for acupuncture in the treatment of primary dysmenorrhea. There is an urgent need for randomized, blinded, placebo-controlled trials to assess the effects of acupuncture.

Beta1- and beta2-adrenoceptors in basolateral nucleus of amygdala and their roles in consolidation of fear memory in rats.

It is known that beta-adrenoceptor (AR) in the basolateral nucleus of amygdala (BLA) plays an essential role in fear memory formation. However, the cellular and subcellular distributions of beta1- and beta2-ARs in the BLA and their roles in fear memory formation are poorly understood. Here, we report that both beta1- and beta2-ARs are predominantly expressed in BLA neurons but not in astrocytes. beta1-AR is distributed in the cell membrane and cytoplasm of neurons, whereas beta2-AR is localized not only in the cell membrane and cytoplasm but also in the nucleus. Intra-BLA infusion of the beta1-AR antagonist metoprolol and atenolol or the beta2-AR antagonist ICI118551 and butoxamine produces a severe deficit in 24-h auditory fear memory, leaving 1-h memory intact. Western-blot analysis reveals that the protein level of cytoplasmic beta1-AR significantly increases 2- and 4-h postconditioning, whereas that of cytoplasmic or nuclear beta2-AR is unchanged. The present results indicate that beta1- and beta2-ARs in the BLA have differential subcellular localizations and both are required for the consolidation of auditory fear memory.

[Clinical study on the indications of 33 acupoints].

Multi-central randomized controlled method was used to scientifically verify indications of 33 acupoints and provide definite clinical basis for the indications of single acupoint. Of the 52 studies, 40 studies showed that the therapeutic effect in acupuncture observation groups were better than the control group; 11 studies showed similar therapeutic effect of the two groups, and 1 study showed the acupuncture observation group was worse than the control group. Therefore, results indicate that in a certain observation cycle, acupuncture at single acupoint have different effects on diseases.

[Review on clinical application of needling techniques in chapter Guan Zhen (Official Needling Techniques) of Ling Shu (Spiritual Pivot)].

In the present paper, more than 380 theses related with clinical application of "nine needling techniques", "twelve needling techniques" and "five needling techniques" recorded in chapter Guan Zhen (Official Needling Techniques) of Ling Shu (Spiritual Pivot) were found through retrieving the data in the internet in latest 10 years. Among the 130 theses about clinical application of "nine needling techniques", 108 involve the application of opposing needling. Of the 180 theses about clinical application of "twelve needling techniques", 95 involve the application of triple needling. Out of the 60 theses on clinical application of "five needling techniques", 37 involve the application of Hegu needling (multi-direction needling). To sum up, the above-mentioned needling techniques were mainly applied to the treatment of diseases of dermatology, surgery, pediatrics, traumatology, five sense organs, etc.. It indicates that these needling techniques are widely being used in clinical practice now. Therefore, researchers should lay the stress on the scientific methodology, rigorous research process, as well as objective analysis of the results so as to make an objective conclusion and improve the level of the research.
