To observe the effect of electroacupuncture (EA) combined with Zhuang-medicine-thread moxibustion on expression of apoptosis-related factors in gastric antrum of diabetic gastroparesis (DGP) rats, so as to explore its mechanism underlying improvement of DGP.

Male SD rats were randomly divided into normal, model, medication, EA, Zhuang-medicine-thread moxibustion (moxibustion) and EA+moxibustion (combination) groups (12 rats in each group). The DGP model was established by intraperitoneal injection of streptozotocin (STZ). Rats of the medication group were treated by gavage of 0.15 mg/mL mosapride citrate suspension （10 mL/kg）. EA (10 Hz/50 Hz, 2 mA, 20 min) or Zhuang-medicine-thread moxibustion (3 cones) was applied to "Zhongwan" (CV12), bilateral "Neiguan" (PC6) and bilateral "Sanyinjiao" (SP6) of the related groups, once a day for 3 weeks. The blood glucose, gastric emptying rate and intestinal propulsion rate of rats were measured. The apoptosis index of gastric antrum cells were observed by TUNEL staiy be related to its effect in regulating of Caspase-3, Bax and Bcl-2 expression.

EA combined with Zhuang-medicine-thread moxibustion can reduce blood glucose and improve gastrointestinal motility in DGP rats, which may be related to its effect in regulating of Caspase-3, Bax and Bcl-2 expression.

To explore the protective effect and molecular mechanism of electroacupuncture (EA) preconditioning on renal injury in type 2 diabetic rats.

Fifty male Wistar rats were randomly divided into control, model, EA, EA+inhibitor, and inhibitor groups, with 10 rats in each group. Diabetes model was established by high fat and high glucose diet and intraperitoneal injection of streptozotocin (40 mg/kg). EA (2 Hz, 1 mA) preconditioning was applied to "Guanyuan" (CV4), "Zhongwan" (CV12), bilateral "Zusanli" (ST36) and "Fenglong" (ST40) for 15 min, once every other day for 8 weeks. Rats of the inhibitor and EA+inhibitor groups were given intraperitoneal injection of 3-TYP (50 mg/kg) once every other day for a total of 3 times. The body weight, kidney mass, and renal index were recorded. The contents of urine microalbumin (ALB), 24 h urine 8-hydroxydeoxyguanosine (8-OHdG) and activities of reactive oxygen species (ROS), superoxide dismutase (SOD), catalase (CAT), glutathione glycine peroxidase (GSH-Px) in kidney werCCⅡ activities, Sirt3 and MnSOD expression levels (

<0.01,

<0.05).

EA preconditioning can increase the expressions of renal Sirt3 and MnSOD in type 2 diabetic rats, thereby reducing the oxidative stress response and protecting the kidneys.

To observe the effect of electroacupuncture (EA) at "Tianshu" (ST25) on nitrergic neurons in jejunum and distal colon in type 2 diabetic rats, so as to explore its mechanism of regulating different intestinal segments.

Twenty-four SD rats were randomly divided into control, model and EA groups (

=8 in each group). The diabetes model was established by intraperitoneal injection of streptozotocin (35 mg/kg) and high-sugar and high-fat diet for 2 weeks. EA (2 Hz/15 Hz, 2 mA) was applied to bilateral ST25 for 20 min, once a day, 6 days a week for 4 weeks. The intestinal motility was evaluated by observing the first red stool excretion time and the distal colon bead excretion time. HE staining was used to observe the histological changes of jejunum and distal colon. The positive expression and protein expression of intestinal total neuronal marker protein gene product 9.5（PGP9.5） and neuronal nitric oxide synthase (nNOS) in jejunum and distal colon were detected by immunofluorescence staining and Western blot related to its function in regulating the number of nitrergic neurons in the intestinal nervous system.

EA can effectively improve the intestinal mucosal damage and restore intestinal motor function in type 2 diabetic rats, which may be related to its function in regulating the number of nitrergic neurons in the intestinal nervous system.

To observe the effect of acupuncture preconditioning combined with PI3K blocker LY294002 on the expression of PI3K and Akt proteins and genes in the lung tissue and the contents of serum IL-12 and IL-13 in asthmatic rats, so as to explore its preprotective mechanism underlying improving asthma.

Sixty male Wistar rats were randomly divided into blank control, model, acupuncture pretreatment + blank, acupuncture pretreatment, acupuncture pretreatment + LY294002 and LY294002 groups (

=10 in each group). The asthma model was established by intraperitoneal injection of mixture solution of OVA and Al(OH)3 and followed inhalation of 1%OVA for 30 min, once daily for 7 days. Rats of the blocker groups received inhalation of atomized LY294002 solution for 30 min before inhalation of 1% OVA, and acupuncture was applied to "Feishu"(BL13), "Dazhui"(GV14) and "Fengmen"(BL12) for 20 min, once daily for 7 days before modeling. H.E. staining was used to assess histopathological changes of the lung tissue, and ELISA was un in asthmatic rats, which may be associated with its functions in down-regulating the levels of pulmonary PI3K and Akt and serum IL-13 and up-regulating the content of serum IL-12. Acupuncture preconditioning combined with LY294002 has the best effect.

To observe the effect of heat-reinforcing needling on the expression of serum inflammatory factors and autophagy of knee synovial tissue in rheumatoid arthritis (RA) rabbits with cold syndrome, so as to explore its mechanism of anti-inflammatory in the treatment of RA.

Fifty rabbits were randomly divided into normal, model, heat-reinforcing needling, inhibitor and agonist groups (

=10 rabbits in each group). The model of RA with cold syndrome was established by Freund's adjuvant and ovalbumin mixed solution injection combined with freezing and wind-cold dampness method. Heat-reinforcing needling was applied at "Zusanli" (ST36) for 30 min, once a day for 14 days. Rabbits of the inhibitor and agonist groups were given intraperitoneally injected with autophagy inhibitor 3-methyladenine (3-MA) or autophagy agonist rapamycin, once every 2 days for 7 days. The knee circumference and skin temperature of the rabbits in each group were measured. Color doppler ultrasonography was applied to examine the synovial med CRP.

Heat-reinforcing needling can alleviate the inflammatory response of the knee joint synovium in RA rabbits with cold syndrome, which may be related to its function in enhancing the autophagy activity of synovial cells and inhibiting the synthesis and release of inflammatory factors TNF-α, IL-1β, IL-6 and CRP.

To study the protective effect of electroacupuncture (EA) at "Biao"-acupoints, "Fenglong"(ST40) and "Zhongwan"(CV12), used for treating symptoms of the disease, and "Ben"-acupoints, "Zusanli"(ST36) and "Guanyuan"(CV4), for treating the root cause of the disease on oxidative stress injury of renal mitochondria through SIRT1/PGC-1α signal pathway in rats with diabetic nephropathy (DN).

A total of 33 male Wistar rats were randomized into normal (

=10), model (

=12) and EA (

=11) groups.The DN model was established by feeding the rats with high-sugar and high-fat diet for 6 weeks combined with streptozotocin (STZ, 35 mg/kg, i.p.). EA (4 Hz/60 Hz, 1 mA)was applied to ST36-ST40 and CV4-CV12 for 15 min, once every other day for 8 weeks. The rats' body weight was recorded, urine in 24 hours (24-h UP) was collected to measure the urine protein level, and the fasting blood glucose (FBG) level detected by using a glucometer. CCT251545 cost The levels of serum glycosylated hemoglobin (HbA1c), creatinine (Scr) and urea nitrogen (ngial matrix accumulation; PAS staining showed an increase of the glomerular extracellular matrix deposition; and Masson staining displayed an enhancement of glomerular fibrosis and interstitial space expansion; and electron microscope revealed foot process fusion, basement membrane thickening and organelle injury in the rat's kidney of the model group, which were relatively milder in the EA group.

EA of ST36-ST40 and CV4-CV12, "Biao-Ben" acupoints combination, can alleviate oxidative stress and mitochondrial dysfunction in DN rats, which may be associated with its functions in up-regulating SIRT1/PGC-1α signaling, and decreasing renal fibrosis.

To observe the effect of electroacupuncture (EA) on miRNA-126-3p and mammalian target of rapamycin (mTOR)/hypoxia-inducible factor-1α (HIF-1α) signaling pathway in rats with cerebral ischemia (CI), so as to explore the underlying mechanism of EA on angiogenesis.

Male SD rats were randomly divided into control group, model group, EA group and EA+inhibitor group (inhibitor group), which were further divided into 3, 7 and 14 d subgroups, with 12 rats in each sub-group. The CI model was established by occlusion of the middle cerebral artery. EA (2 Hz/20 Hz, 0.5 mA) was applied to "Dazhui" (GV14), "Baihui" (GV20) for 20 min, once daily for 14 days at most. Rats of the inhibitor group were given an intraperitoneally injection of mTOR inhibitor (0.1 mg/mL, 0.3 mg/kg) before daily EA. The neurological function was evaluated by modified neurological severity score (mNSS). The ultrastructure of cortical neurons and microvascular endothelial cells in ischemic penumbra was observed by transmission electron microscopetself at day 3, the mRNA expressions of mTOR and HIF-1α were increased at day 7 and day 14 (

<0.01,

<0.05) in the inhibitor group.

EA at GV14 and GV20 can alleviate neurological deficit and improve angiogenesis in rats with CI, which may be related with its effect in up-regulating the expression of mTOR and HIF-1α, improving activation of miR-126-3p in the cortex of ischemic penumbra.

The COVID-19 pandemic resulted in a particularly adverse and stressful environment for expecting mothers, possibly enhancing feelings of anxiety and parenting stress. The present work assesses mothers' anxiety levels at delivery and parenting stress after 3months as moderated by home-visiting sessions.

Women (n = 177) in their second or third trimester of pregnancy during the COVID-19 lockdown were enrolled in northern Italy and split into those who did and did not receive home visits. After 3months, the association between anxiety at delivery and parenting stress was assessed with bivariate correlations in the whole sample and comparing the two groups.

Higher anxiety at birth correlated with greater perceived stress after 3months. Mothers who received at least one home-visiting session reported lower parenting stress at 3months than counterparts who did not receive home visits. CONCLUSIONSFOR PRACTICE The perinatal period is a sensitive time window for mother-infant health, especially during a critical time like the COVID-19 pandemic.
