Objective To investigate the level of benefit finding and positive psychological capital of stroke patients and their spouses,and to analyse the dyadic interaction between benefit finding and positive psychological capital of patients and their spouses.Methods From March to August 2023,235 stroke patients and their spouses were conveniently selected from the neurology wards of 3 tertiary hospitals in Henan Province,and were surveyed using a general information questionnaire,the positive psychological capital questionnaire,revised version of benefit finding scale,and caregiver benefit finding scale.Results The positive psychological capital scores of stroke patients and their spouses were(4.29±0.75)and(4.56±0.71);benefit finding scores of the dyads were(2.85±0.69)and(3.64±0.68).The results of actor-partner interdependence model showed that positive psychological capital of stroke patients and their spouses positively predicted their benefit finding;positive psychological capital of patients positively predicted benefit finding of spouses,and positive psychological capital of spouses positively predicted benefit finding of patients(all P＜0.05).In particular,spousal self-efficacy and resilience positively predicted their benefit finding;their optimism positively predicted the patient's benefit finding;their hopefulness negatively predicted the patient's benefit finding(all P＜0.05).Conclusion There was a dyadic interaction between benefit finding and positive psychological capital for stroke patients and their spouses.The role of spouses on patients'positive psychological capital should not be overlooked,and nurses should develop positive psychological capital intervention strategies centered on couples of stroke patients to enhance positive couple experiences.

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.

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.

The onset time of the first cry, the duration of crying, the onset time of the first painful face, the duration of the painful face in the experimental group were (41.55 ± 6.38), (22.05 ± 4.47), (35.08 ± 5.94), (24.65 ± 5.46) s, significantly shorter than those in the control group (46.58 ± 5.26), (29.50 ± 6.48), (44.68 ± 13.31), (30.65 ± 9.42) s, the differences were statistically significant (t values were 2.63-5.98, all P<0.05). Conclusions:Oral stimulation combined with maternal milk sucking can effectively relieve the pain caused by PICC in children with congenital digestive tract malformation, and reduce the physiological stress response of children.

OBJECTIVE：To study the mechanism of improvement effects of Fupi rougan granule （FRG）on hepatic fibrosis model rats. METHODS ：The rats were randomly divided into blank group ，model group ，Colchicine tablet group （chemical positive control ，0.2 mg/kg），Fuzheng huayu capsule group （TCM positive control ，0.415 g/kg），FRG low-dose ，medium-dose and high-dose groups （20，40，80 g/kg），with 10 rats in each group ，except for 11 rats in blank group and model group （one rat was used to judge whether the modeling was successful ）. Except for blank group ，other groups were given intraperitoneal injection of 50％ CCl4 olive oil solution and intragastric administration of 30％ ethanol to induce hepatic fibrosis model. After modeling ， administration groups were given relevant medicine intragastrically ；blank group and model group were given constant volume of normal saline intragastrically ，once a day ，for consecutive 4 weeks. After last administration ，morphology changes of liver tissue in rats were observed. The serum levels of HA ，LN，PCⅢ and Col Ⅳ in rats were detected ，and protein expression of Beclin- 1 and LC3-Ⅱin liver tissue were also determined. mRNA and protein expression of Akt ，AMPK，mTOR，p70S6K were detected in liver tissues of rats. RESULTS ：Compared with blank group ，the structure of hepatic lobules in the model group was disordered ，the proliferation of fibrous tissue was obvious ，and some pseudolobules were formed ；the serum levels of HA ，LN，PCⅢ and Col Ⅳ， the protein expression of Beclin- 1 and LC 3-Ⅱ in liver tissue as well as mRNA and protein expression of Akt ，AMPK，mTOR and p70S6K were increased significantly （P＜0.01）. Compared with model group ，the liver injury of rats in FRG groups was significantly relieved ，and the levels of the above indexes in serum and liver tissue （except for LN and PC Ⅲ in FRG low-dose group） were significantly reduced （P＜0.05 or P＜0.01）. CONCLUSIONS ：FRG can improve hepatic fibrosis in rats ，the mechanism of which may be associated with down-regulating the expression of autophagy associated protein and Akt/AMPK/mTOR/ p70S6K signaling pathway related protein.

Objective: To investigate the application of music intervention in combination with maternal voice during PICC placement procedures in malformation alimentary tract infants. Methods: A total of 60 malformation alimentary tract infants were enrolled in the present study in Hunan Children Hospital from January to December 2018, infants were randomly assigned to the intervention group (n=30) and the control group (n=30). Patients in the control group received conventional nursing, the intervention group received music and maternal voice intervention method. The level changes of heart rate, respiratory rate, blood pressure, blood oxygen saturation and cortisol concentration were compared between two groups, meanwhile, the pain rating were assessed by Neonatal Infant Pain Scale (NIPS). Results: Before procedure, no significant difference was found between the control and intervention group in heart rate, respiratory rate, systolic pressure, SpO₂ and NIPS score (P>0.05). During and after the procedure, the mean heart rate [(144.43±15.93), (142.43±20.42) times/min], respiratory rate [(44.70±4.51) and (43.50± 4.12) times/min], systolic pressure [(87.40±8.53) and (86.10±4.60) mmHg] and NIPS score (5.34±0.71 and 5.19±0.87) of the intervention group was statistically lower compared to the control group [(160.97±39.35) and (159.17±31.87) times/min, (53.13±7.85) and (50.47±7.70) times/min, (97.60±9.82) and (94.27±7.23) mmHg, 6.17±0.54 and 6.15±0.66; during procedure, the mean SpO₂ was statistically significantly higher, compared to the control group [(96.15±9.82)% versus (88.34±9.53)%]. The difference was statistically significantly (t=2.134-6.682, P<0.05). Before placement, the concentration of cortisol between the two groups showed no significant difference (P>0.05), and (208.91±21.07)ng/ml 5min after placement and (197.70±16.34) ng/ml immediately after placement, the cortisol concentration was statistically significantly lower, compared to the control group [(246.71±35.15), (230.95±21.81) ng/ml] (t=5.050-6.682, P<0.05). Compared with the control group, the time needed for PICC placement decreased remarkably in the intervention group [(15.62±3.30) min versus (24.63±4.26) min)](t=9.160, P<0.01). Conclusions Music in combination with maternal voice can significantly reduce stress levels, pain responses and time need for PICC placement, music and maternal voice is a potential intervention strategy in malformation alimentary tract infants undergoing PICC.

Conclusion Acupuncture plus medicine and function training can enhance the efficacy in treating post-stroke shoulder-hand syndrome, superior to pure function training.

OBJECTIVETo investigate the levels and influencing factors of phthalate internal exposure in pregnant women (gestation age ≤ 16 weeks).

METHODSDuring April to June in 2013, 1 020 pregnant women (gestation age ≤ 16 weeks) who had established the maternal care manual were recruited in maternal and child health hospital of Siming District, Xiamen city. Participators were asked to complete a questionnaire to obtain information on socio-demographic characteristics, lifestyle behaviors, and antenatal examination and to provide a urine sample. Finally, 998 pregnant women who provided a urine sample and completed the questionnaire were enrolled. Adopting systematic sampling method, 100 ones were selected randomly among 998 pregnant women. High performance liquid chromatography-electrospray ionization-tandern mass was used to determine the concentration of five phthalate monoesters in each urine, including mono-n-methyl phthalate (MMP), mono-ethyl phthalate (MEP), mono-butyl phthalate (MBP), mono-benzyl phthalate (MBzP), mono-ethylhexyl phthalate (MEHP). Based on the measurements and questionnaire data, multivariate logistic regression was used to analyze the association between the phthalate monoester levels and potential influential factors.

RESULTSThe detection rates of MMP, MEP, MBP, MBzP and MEHP in 100 pregnant urine samples were 94%, 93%, 87%, 83%, 99%, respectively. And the urinary median uncorrected concentrations of MMP, MEP, MBP, MBzP and MEHP in 100 urine samples were 20.56, 17.62, 10.15, 2.03, and 5.12 ng/ml, respectively. Specific gravity-corrected concentration were 20.81, 20.36, 12.88, 2.58, 5.00 ng/ml, respectively. The results of multivariate logistic regression analysis indicated that: education degree was negatively associated with urinary concentration of MMP, MEP, MBP, MBzP and MEHP, OR (95% CI) were 0.495 (0.253-0.966), 0.380 (0.191-0.755), 0.379 (0.186-0.774), 0.401 (0.196-0.819), 0.373(0.183-0.762), respectively. Participants who had hair permed and dyed during pregnancy had higher urinary level of MBP and MBzP, OR (95% CI) were 12.867 (1.240-133.525), 15.982 (1.367-186.911), respectively; Participants who use cosmetics during pregnancy had higher urinary level of MEP and MBP, OR (95% CI) were 2.977 (1.012-8.757), 4.440 (1.485-13.272), respectively; plastic bottled water consumption was positively associated with urinary concentrations of MEP and MEHP, OR (95% CI) were 3.780 (1.417-10.083), 2.699 (1.039-7.010), respectively; annual household income was negatively associated with urinary concentration of MMP, OR (95% CI) was 0.597 (0.372-0.959); individuals who took medications during pregnancy had higher urinary level of MEHP than non-takers, OR (95% CI) was 4.853 (1.084-21.732).
