Objective To explore the differences of coronary computed tomography-derived fractional flow reserve(CT-FFR)and dynamic stress computed tomography myocardial perfusion imaging(CT-MPI)parameters in obstructive coronary artery disease(CAD),and their correlation with coronary computed tomography angiography(CCTA)vessel stenosis.Methods A retrospective analysis was conducted on 37 patients with obstructive CAD who underwent combined CCTA and dynamic stress CT-MPI scans.Based on the CCTA results,the patients were divided into moderate CAD group(22 cases)and severe CAD group(15 cases).The lowest CT-FFR value and perfusion parameter values between the two groups were analyzed.A total of 111 vessels including the left anterior descending branch(LAD),left circumflex branch(LCX),and right coronary artery(RCA)were classified into the mild vessel stenosis group(＜25％)with 42 vessels,moderate vessel stenosis group(25％-69％)with 49 vessels,and severe vessel stenosis group(≥70％)with 20 vessels.The lowest CT-FFR value and lowest perfusion parameter value among these three groups were analyzed.The correlation between CT-FFR value and CT-MPI perfusion parameter values and their diagnostic efficacy were analyzed.Results At the patient level,the relative myocardial blood flow(rMBF),myocardial blood flow(MBF),myocardial blood volume(MBV),flow extraction product(FEP)in the severe CAD group were significantly lower than those in the moderate CAD group(P＜0.05),while there was no significance in CT-FFR and perfusion capillary blood volume(PCBV)between these two groups(P=0.061,0.098).At the vascular level,there were significant differences in rMBF and MBV among mild,moderate,and severe vessel stenosis groups(P＜0.05).CT-FFR showed significant difference between mild vs moderate vessel stenosis groups and mild vs severe vessel stenosis groups(P＜0.001),and no significant difference between moderate and severe vessel stenosis groups(P=0.355).rMBF had the highest correlation with the degree of vessel stenosis(r=-0.674).CT-MPI combined with CT-FFR had a high efficacy in diagnosing CCTA vessel stenosis,area under the curve(AUC)≥0.90.Conclusion rMBF is more effective than CT-FFR in evaluating the degree of vessel stenosis in CCTA.CT-FFR combined with CT-MPI is helpful to evaluate functional vascular stenosis.

Objective:To analyze the effects of parenting care map of premature infants on parenting competence and parenting stress of primipara, with a view to providing a theoretical basis for the development, implementation and modification of clinical interventions.Methods:Convenient sampling method was used to select primigravid women who gave birth in Lishui Maternal and Child Health Hospital from January 2023 to January 2024 for randomized controlled study, which was divided into the observation group and the control group according to the random number table. The control group received routine nursing, and the observation group guided the parents of premature infants to draw the child care map together on the basis of the control group. The scores of Chinese version of parenting sense of competence scale ( C-PSOC ) and Chinese version of Simplified Parenting Stress Index ( PSI-SF ) before and after intervention were compared.Results:A total of 120 cases of primiparous women who met the inclusion and exclusion criteria were enrolled, 60 cases in the control group and 60 cases in the observation group. The age of the control group was (26.25 ± 3.93) years, and the age of the observation group was (25.86 ± 4.22) years. Before the intervention, the difference between the C-PSOC dimension scores and total scores, PSI-SF dimension scores and total scores of the 2 groups was not statistically significant (all P>0.05). After the intervention, the maternal C-PSOC efficacy, satisfaction dimension scores and total scores of primiparous women in the observation group were (32.05 ± 6.27), (40.29 ± 8.19), and (72.23 ± 9.39) points, respectively, which were higher than those of the control group, which were (28.46 ± 6.47), (37.08 ± 8.06), and (65.53 ± 10.24) points, and the differences between the 2 groups were all statistically significant ( t = 3.09, 2.16, 3.74, all P<0.05). After the intervention, the PSI-SF scores and total scores of primiparous women in the observation group on the dimensions of parental distress, personal interaction disorder, and difficult child were (24.43 ± 5.44), (27.51 ± 6.53), (29.47 ± 5.82), and (81.54 ± 10.38) points, respectively, which were lower than those of the control group (28.57 ± 5.52), (30.19 ± 7.02), (32.78 ± 5.37), and (90.97 ± 10.12) points, and the differences between the 2 groups were all statistically significant ( t = 4.41, 2.17, 3.23, 5.04, all P<0.05). Conclusions:Premature child care map can effectively improve the parenting sense of competence of primiparas and reduce their parenting pressure. It is a convenient and effective nursing intervention tool.

P21-activated kinase 5 (PAK5) belongs to the PAK-II subfamily, which is an important regulator of cell survival, adhesion, and motility. However, the functions of PAK5 in endometriosis remain unclear. Here, PAK5 is strikingly upregulated in endometriosis. Furthermore, the knockdown of PAK5 or its inhibitor GNE 2861 blocks the development of endometriosis, which is equally demonstrated in PAK5-knockout mice. In addition, PAK5 promotes glycolysis by enhancing the protein stability of pyruvate kinase 2 (PKM2) in endometriotic cells, which is a key enzyme for glucose metabolism. Moreover, the phosphorylation of PKM2 at Ser519 by PAK5 mediates endometriosis cell proliferation and metastasis. Collectively, PAK5 plays an indispensable role in endometriosis. Our findings demonstrate that PAK5 is an important target for the treatment of endometriosis.

Objective: This article investigated the clinical characteristics and distribution of drug resistance mutation sites in HBV RT region of hepatitis B infected patients. Methods: Retrospective analysis was made on 1 948 patients with HBV infection, who had been tested for NAs resistance mutation and had a medical history of NAs in the Laboratory Department of the Fifth Medical Center of the PLA General Hospital from January 2020 to December 2021. Basic clinical information and drug resistance related mutation information were recorded. Meanwhile, the serological index data of hepatitis B were collected. Drug resistance gene mutant group and non-mutated group were grouped according to whether the drug resistance genes had a mutation in HBV RT region, and the clinical characteristics and genotype distribution of the two groups were statistically analyzed. The pattern of drug resistance gene mutation, number of mutation sites, drug resistance type and mutation of NAs resistance-related sites were analyzed in 917 patients with drug resistance gene mutation in HBV RT region. χ² Inspection was used for counting data. Meanwhile, two independent samples t-test and Wilcoxon rank sum test were used for measurement data. Results: Among the 1 948 patients with chronic HBV infection, 917 patients had drug resistance gene mutation in RT region (47.07%). The proportion of patients with acute hepatitis B and CHB in HBV RT resistance gene mutant group was lower than that in the non-mutated group, while the proportion of patients with HBV-related cirrhosis was higher than that in the non-mutated group, these differences were statistically significant. Compared with the non-mutated group in HBV RT region, the age, the positive rates of HBeAg and HBV DNA, and HBV DNA load of these patients were increased in drug resistance gene mutant group, these differences were statistically significant. Genotypes of patients in both groups were dominated by C, followed by B and D. The proportion of patients with genotype C in HBV RT drug resistance gene mutant group was higher than that of non-mutated group, the difference was statistically significant. There were 53 gene mutation patterns in 917 patients with drug resistance gene mutation in HBV RT region, and the main pattern was rtL180M+rtM204V+rtS202G (9.70%). The mutation sites were dominated by 3 (20.74%). There were 5 types of drug resistance, LAM+Ldt (21.25%) was the most. Among the 18 sites that were clearly associated with LAM, ADV, ETV and Ldt resistance in the HBV RT region, 14 sites were mutated, and the most common mutation sites were rtL180M, rtM204V, rtM204 and rtS202G. what's more, the proportion of patients with NAs drug resistance was LAM>Ldt>ETV>ADV. Conclusion: In order to prevent adverse consequences of this study such as disease recurrence or disease progression caused by HBV drug resistance, HBV infected patients, who have long-term use of NAs antiviral therapy, should monitor the level of HBV DNA and drug resistance genes in HBV RT region in order to optimize the treatment plan in time or guide individualized treatment.

OBJECTIVE: To compare the curative effect of panlong needling at Jiaji (EX-B 2) combined with western medication and western medication alone on motor dysfunction in patients with Parkinson's disease (PD) of liver and kidney deficiency. METHODS: A total of 98 patients with PD were randomly divided into an acupuncture and medication group (49 cases, 1 case dropped off) and a western medication group (49 cases,1 case was removed). The patients in the western medication group were given oral of levodopa and benserazide hydrochloride tablets, 125 mg each time, three times a day in the 1st week, and the dose was increased according to the needs of the patients' condition from the 2nd week until 250 mg each time, three times a day, for 16 consecutive weeks. On the basis of the same western medication treatment as the western medication group, panlong needling was applied at Jiaji (EX-B 2) from C₂ to L₅ in the acupuncture and medication group, once a day, 20 times as a course of treatment, for 4 consecutive courses. The scores of unified Parkinson's disease rating scale (UPDRS-Ⅲ, UPDRS-Ⅳ), TCM symptoms score, and 39-item Parkinson's disease questionnaire (PDQ-39) score were evaluated before treatment, after treatment and during follow-up of 1 month after treatment, respectively. The safety of the two groups was compared. RESULTS: After treatment and during follow-up, except the PDQ-39 score of the western medication group, the scores of UPDRS-Ⅲ, UPDRS-Ⅳ, TCM syndrome and PDQ-39 were lower than those before treatment in the two groups (P<0.05), and the scores of above indexes in the acupuncture and medication group were lower than those of the western medication group (P<0.05). The total incidence of adverse reactions in the acupuncture and medication group was 10.4% (5/48), which was lower than 29.2% (14/48) in the western medication group (P<0.05). CONCLUSION Panlong needling at Jiaji (EX-B 2) combined with western medication could significantly improve the motor dysfunction and clinical symptoms, improve the quality of life and has high safety, and the efficacy is superior to western medication alone.
