To observe the influence of acupuncture on the expression of pivotal molecules of Nod-like receptor protein 3(NLRP3) inflammasome signal pathway in the prefrontal cortex of rats with depression, so as to explore the underlying mechanism of acupuncture on treatment of depression.

SD rats were randomly divided into 4 groups (8 rats/group)，namely control, model, acupuncture and fluoxetine groups. The depression model was established by using chronic unpredictable mild stress for 6 weeks. During modeling, acupuncture (10 min)was applied to "Baihui"(GV20) and "Yintang"(EX-HN3) for rats of the acupuncture group once a day, with 1 day interval after consecutive 6 day-period for 36 days. Fluoxetine was given (10 mg/kg，1 mg/mL) by gavage to rats of the fluoxetine group every day during modeling for 42 days. The novelty-suppressed feeding test was used to observe feeding behavior of rats. The expressions of NLRP3 and apoptosis associated speck like protein containing a CARD (ASC), Caspase-1, and contents of IL-1β il cortex, and reduce the inflammation in the brain, which may mediate the anti-depressant effect of acupuncture.

To observe the effects of mild moxibustion on the expression of autophagy and apoptosis factors Beclin-1, Bcl-2 mRNA and protein in spinal cord (including nerve root tissues) of cervical spondylotic radiculopathy (CSR) rats, so as to explore the analgesic mechanism of mild moxibustion at "Dazhui" (GV14) on CSR.

SD rats were randomly divided into blank group, model group, mild moxibustion group and mild moxibustion+3-methyladenine(3-MA) group, with 10 rats in each group. CSR model was established by inserting the wire into the cervical nerve root. The rats in the blank group were only fed normally without any intervention.The rats in the mild moxibustion group and mild moxibustion+3-MA group were given mild moxibustion at GV14 for 10 min each time,and intraperitoneal injection of 1 mL 0.9% normal saline and 1 mL 3-MA(15 mg/kg)separately. Rats in the model group were given 0.9% normal saline every day. All the three interventions were started from the 3rd day after modeling for 7 days. The rat's behavioral f the above indicators as more significant in the mild moxibustion group than that in the mild moxibustion+3-MA group (

<0.05). After modeling, the organelles in the spinal nerve root tissue cells of the model group were damaged and there were a small amount of autophagosomes. Compared with the model group, the ultrastructure of the spinal nerve root tissue cells in the mild moxibustion group were relatively complete, and the number of autophagosomes increased.

Mild moxibustion at GV14 has a good analgesic effect on CSR rats, which may be related to its effects in up-regulation of Beclin-1 and Bcl-2 expressions and activation of autophagy and inhibition of apoptosis.

To observe the effect of moxibustion on expression of autophagy related gene(Atg), serine/threonine protein kinase-uncoordinated 51 like kinase-1 (ULK1), Beclin1 and microtubule associated proteins light chain 3 (LC3) and ultrastructure of synovium in rheumatoid arthritis (RA) rats, so as to explore its mechanisms underlying improvement of RA.

Forty SD rats were randomly divided into normal control, RA model, moxibustion, cigarette-roasting and medication groups (

=8 rats in each group). The RA model was established by keeping the rats in wind, cold and wet environment for 12 h, once a day for 20 days and subcutaneous injection of Freund's adjuvant complete into the sole of the left hind paw. Moxibustion was applied to the left "Zusanli" (ST36) for 20 min, once a day for 15 days. Rats of the cigarette-roasting group was treated by ignited cigarettes instead of moxa strips. Rats of the medication group was treated by gavage of Tripterygium wilfordii polyglycoside tablet suspension (0.8 mg/100 g) once a da tissue in RA rats, which may be related to its effects in up-regulating Atg3, Atg5, Atg12 and ULK1 mRNAs, and LC3-Ⅱ and Beclin-1 proteins to enhance the cellular autophagy. The therapeutic effect of moxibustion is obviously superior to that of cigarette-roasting and medication in relieving swelling.

Moxibustion can reduce the paw edema and inflammatory injury of the plantar synovial tissue in RA rats, which may be related to its effects in up-regulating Atg3, Atg5, Atg12 and ULK1 mRNAs, and LC3-Ⅱ and Beclin-1 proteins to enhance the cellular autophagy. The therapeutic effect of moxibustion is obviously superior to that of cigarette-roasting and medication in relieving swelling.

To observe the effect of electroacupuncture (EA) on the expression of soluble guanylate cyclase (sGC), cyclic guanosine phosphate (cGMP) and protein kinase G (PKG) of cerebral vascular smooth muscle in cerebral infarction (CI) rats, so as to study its dynamic regulation mechanism.

Male Wistar rats were randomly divided into normal control (

=10), sham operation (

=40), model (

=40), and EA (

=40) groups, and the latter three groups were further di-vided into 3, 6, 12 and 24 h subgroups (

=10 in each subgroup). The CI model was established by occlusion of the middle cerebral artery (MCAO). EA(15 Hz, 2 mA)was applied to "Shuigou" (GV26) for 20 min. The cGMP, sGC and PKG activity and expression levels in the vascular smooth muscle of cerebral artery were detected using ELISA and Western blot, respectively.

After modeling, the immunoactivity and activities of sGC at 3 h, PKG at 3 and 6 h and cGMP from 3 h to 24 h were ob-viously decreased in the model group relevant to the normal control and sham-operaHowever, acupuncture effect has a certain time-effectiveness.

To observe the effect of moxibustion on learning-memory ability and expression of hippocampal inflammatory factors and microtubule-associated protein doublecortin (DCX, a marker of neuronal regeneration) in vascular dementia (VD) rats, so as to explore its mechanisms underlying improvement of VD.

SD rats were randomly divided into normal control, sham operation, VD model, moxibustion and medication groups (

=15 rats in each group). https://www.selleckchem.com/products/tdi-011536.html The VD model was established by repeated occlusion of the bilateral common carotid arteries and reperfusion. Moxibustion was applied to "Guanyuan" (CV4), "Mingmen" (GV4) and "Dazhui"(GV14) for 15 min, once a day, 6 days a week for 4 weeks. Rats of the medication group were treated by gavage of Nimodipine (2mg·kg

·d

) 3 times daily for 4 weeks. Morris water maze test was used to detect the average escape latency of location navigation tasks for assessing the rats' learning-memory ability. H.E. staining was used to detect histopathological changes of the hippocampus tissue. The number of DCX-positive neurons (DCX/NeuN co-expression) in the dentate gyrus (DG) region of hippocampus was counted under microscope after immunofluorescence double staining, the immunoactivity of hippocampal DCX detected by using immunohistochemistry stain and the expression of DCX, TNF-α, IL-1β, MPO, NF-κB p65 and IL-6 proteins in the hippocampus tissue detected using Western blot.
