OBJECTIVE To investigate the improvement effects of glycyrrhizin （GL） on Helicobacter pylori （HP）-associated gastritis in rats and its mechanism. METHODS HP-associated gastritis rat model was induced by inoculating with 1×109 cfu/mL HP. The model rats were randomly divided into model group， positive control group （HP standard quadruple group）， GL low-dose， medium-dose and high-dose groups （5， 20， 50 mg/kg）， with 12 rats in each group. Another 12 healthy rats were selected as normal control group. Except the normal control group and model group were given constant volume of normal saline intragastrically， the other groups were given corresponding drugs intragastrically， once a day， for 30 consecutive days. After administration， rats received 13C urea breath test， and delta-over-baseline （DOB） was recorded； the pathological and cellular morphological changes of gastric mucosa in rats were observed， and pathological scoring was performed； the levels of interleukin-8 （IL-8）， IL-1β， tumor necrosis factor-α （TNF-α）， reactive oxygen species （ROS） and malondialdehyde （MDA） were detected in gastric mucosa of rats； mRNA expressions of high mobility group box-1 protein （HMGB1） and nuclear factor-κ-B （NF-κB）， relative expressions of nitric oxide synthases （iNOS） and HMGB1， the phosphorylation level of NF- κBp65 were also detected in rats. RESULTS Compared with normal control group， the DOB value， histopathological score of gastric mucosa， the levels of IL-8， IL-1β， TNF-α， ROS and MDA， relative expressions of HMGB1 and NF- κB mRNA， relative expressions of iNOS and HMGB1 protein and the phosphorylation level of NF-κB p65 were all increased significantly in model group （P＜0.05）； the epithelial cells of gastric mucosa in rats were incomplete in structure and decreased in the number， with an increase in cell fragments and vacuoles， and significant cell pyknosis. Compared with model group， the changes of the above indexes in GL groups and positive control group were significantly reversed （P＜0.05）； the changes in the above indicators in the GL high-dose group were more significant than GL low-dose and medium-dose groups （P＜0.05）； the pathological changes of gastric mucosal cells in rats had all improved. CONCLUSIONS GL may inhibit inflammation and oxidative stress by inhibiting the activation of HMGB1/NF-κB pathway， thus relieving HP-induced gastric mucosal injury.

Objective To investigate radiation doses to examinees undergoing computed tomography (CT) scanning of different body parts (the head, chest, and abdomen) in medical institutions of Shijiazhuang, China, and to provide a reference for optimizing radiation protection for examinees in medical institutions. Methods March 2021 to March 2022, eleven medical institutions of radiation monitoring in Shijiazhuang were surveyed for the basic information, scanning parameters, and dosimetric data of a total of 930 adults and children who received CT examinations. The dosimetric data of the subjects were analyzed and compared with the domestic and international diagnostic reference levels and the results of other cities in China. Results In the above hospitals, the CTDI_vol(P₅₀) of CT subjects in children's group were 17.42-50.45 mGy, 2.13-14.01 mGy and 3.58-28.20 mGy, respectively. DLP(P₅₀) ranges from 228.87 to 966.97 mGy·cm, 33.20 to 296.03 mGy·cm, and 74.90 to 926.53 mGy·cm, respectively. In the adult group, the CTDI_vol(P₅₀) in the head, chest and abdomen of CT subjects were 37.28-54.05 mGy, 6.43-14.99 mGy and 8.28-18.75 mGy, respectively. DLP(P₅₀) ranges from 372.81 to 630.56 mGy·cm, from 219.77 to 467.93 mGy·cm, and from 313.86 to 689.87 mGy·cm, respectively. The distribution of radiation doses in different-grade hospitals varied greatly. The abdomen dose of the children's hospital was higher than other hospitals. Especially the primary hospitals were significantly higher than the recommended diagnostic reference level (DRL). Conclusion In some secondary and primary hospitals, the setting of CT scanning parameters was simplified, not specific to the subjects’ age and body types. They should strictly comply with the principal of optimizing radiation protection to strengthen radiation dose optimization and supervision, reducing the radiation dose of examinees in future examinations .

ObjectiveTo investigate the effects of Asari Radix et Rhizoma-Zingiberis Rhizoma herb pair （XGHP） on lung and liver lipid metabolism in rats with chronic obstructive pulmonary disease （COPD）. MethodForty SD male rats were divided into a normal group （10 rats） and a model group （30 rats）. The method of cigarette smoke + tracheal injection of lipopolysaccharide（LPS） + cold stimulation was used to replicate COPD model with the syndrome of cold phlegm obstruction in lung. A COPD group， a XGHP group （5.4 g·kg^-1·d^-1）， and an aminophylline group （0.5 g·kg^-1·d^-1） were established after successfully inducing the model， with 10 rats in each group. After treatment， the serum triglyceride （TG）， total cholesterol （TC）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C） levels of rats in each group were measured. Gas chromatography-mass spectrometer （GC-MS） was used to detect the differential metabolites in the lung and liver tissues of rats in each group， and the relevant targets of the differential metabolites were predicted by network pharmacology. Molecular docking was used to verify the binding ability of key components in XGHP to the relevant targets in network pharmacology. The mRNA and protein expression levels of peroxisome proliferator-activated receptor α （PPARα） and fatty acid binding protein 4 （FABP4） in lung and liver tissues of rats in each group were detected by real-time polymerase chain reaction （PCR） and Western blot. ResultXGHP significantly increased the levels of TG， TC， and LDL-C in serum （P<0.05）， and decreased the level of HDL-C （P<0.05） in rats with COPD. GC-MS results showed that there were 8 lung differential metabolites and 17 liver differential metabolites in the COPD group and XGHP group. Network pharmacology predicted 59 common targets for the two differential metabolites， mainly enriched in the PPAR signaling pathway. Molecular docking results showed that the main components in XGHP were well combined with both PPARα and FABP4. Real-time PCR showed that XGHP effectively up-regulated the expression levels of PPARα and FABP4 mRNA （P<0.05）， and Western blot showed that XGHP effectively up-regulated the expression levels of PPARα and FABP4 proteins （P<0.05） in lung and liver tissues of rats with COPD. ConclusionXGHP effectively improves the blood lipid levels of rats with COPD， which may be related to the increase of the expression levels of PPARα and FABP4 mRNA and proteins in the PPAR signaling pathway， thus regulating lung and liver lipid metabolism.

OBJECTIVEOn the basic therapy, to assess the clinical effects of dynamic scalp acupuncture, scalp acupuncture combined with proprioceptive neuromuscular facilitation (PNF) therapy and simple PNF therapy for upper limb motor impairment in ischemic post-stroke spastic hemiplegia.

METHODSA total of 90 cases were randomly assigned into a PNF group, a dynamic scalp acupuncture group and a scalp acupuncture group, 30 cases in each group. Basic therapy and PNF therapy were applied in the three groups. PNF therapy was used during scalp acupuncture in the dynamic scalp acupuncture group. PNF therapy was applied after scalp acupuncture in the scalp acupuncture group. The points were the upper 1/5 and middle 2/5 of (MS 6) and (MS 7) at the lesion side, the hemiparalysis contralateral side. The treatment was given for 6 months, once a day and 1 month as a course. The modified Ashworth scale (MAS), the Fugl-Meyer motor assessment (FMA) and Barthel index (BI) were observed before treatment and 2 weeks, 1 month, 3 months, and 6 months after treatment.

RESULTSThe MAS 1 month, 3 months and 6 months after treatment were improved compared with those before treatment in the three groups ( all <0.05), and the MAS results in the dynamic scalp acupuncture group were better than those in the PNF and scalp acupuncture group (all <0.05). The FMA and BI scores 1 month, 3 months and 6 months after treatment were higher than those before treatment (all <0.05). The FMA Scores in the 3 time points and after treatment in the dynamic scalp acupuncture group were higher than those in the other two groups (all <0.05).

CONCLUSIONPNF therapy during scalp acupuncture can relieve the spasmodic condition of patients with upper limb motor impairment in ischemic post-stroke spasmodic hemiplegia, and improve the limb function and life activity, which is better than PNF therapy after scalp acupuncture and simple PNF therapy.
