OBJECTIVE To investigate the clinical efficacy of integrating pharmacists into family health teams （FHTs） for long-term medication therapeutical management （MTM） in stroke patients， and empirically evaluate the service model. METHODS A pharmacist team， jointly established by clinical and community pharmacists from the Affiliated Suzhou Hospital of Nanjing Medical University （hereinafter referred to as “our hospital”）， developed a pharmacist-supported MTM model integrated into FHTs. Using a prospective randomized controlled design， 170 stroke patients discharged from our hospital （July 2022-December 2023） and enrolled in FHTs at Suzhou Runda Community Hospital were randomly divided into trial group （88 cases） and control group （82 cases） according to random number table. The control group received routine FHTs care （without pharmacist involvement in the team collaboration）， while the trial group xhz8405@126.com received 12-month MTM services supported by pharmacists via an information platform. These services specifically included innovative interventions such as personalized medication regimen optimization based on the MTM framework， dynamic medication adherence management， medication safety monitoring， a home medication assessment system， and distinctive service offerings. Outcomes of the 2 grousp were compared before and after intervention， involving medication adherence （adherence rate， adherence score）， compliance rates for stroke recurrence risk factors [blood pressure， low-density lipoprotein cholesterol （LDL-C）]， and incidence of adverse drug reactions （ADR）. RESULTS After 12 months， the trial group exhibited significantly higher medication adherence rates， improved adherence scores， higher compliance rates for blood pressure and LDL-C targets compared to the control group （P＜0.05）. The incidence of ADR in the trial group （4.55%） was significantly lower than that in the control group （8.11%）， though the difference was not statistically significant （P＞ 0.05）. CONCLUSIONS Pharmacist involvement in FHTs to deliver MTM services significantly enhances medication adherence and optimizes risk factor for stroke recurrence， offering practical evidence for advancing pharmaceutical care in chronic disease management under the family doctor system.

Alzheimer's disease (AD) is regarded as a neurodegenerative disease, and it has been proposed that AD may be a systemic disease. Studies have reported associations between non-neurological diseases and AD. The correlations between AD pathology and systemic (non-neurological) pathological changes are intricate, and the mechanisms underlying these correlations and their causality are unclear. In this article, we review the association between AD and disorders of other systems. In addition, we summarize the possible mechanisms associated with AD and disorders of other systems, mainly from the perspective of AD pathology. Regarding the relationship between AD and systemic pathological changes, we aim to provide a new outlook on the early warning signs and treatment of AD, such as establishing a diagnostic and screening system based on more accessible peripheral samples.

Objective:To explore the status of cancer health literacy of female patients with breast cancer and analyze its influencing factors, in order to provide a reference for formulating targeted interventions to promote the cancer health literacy of female breast cancer patients.Methods:A cross-sectional survey was conducted. From December 2021 to July 2022, 200 female breast cancer patients hospitalized in Hunan Cancer Hospital were investigated with general information questionnaire, chronic disease patients ′ Health Literacy Management Scale (HeLMS), Strategies Used by People to Promote Health (SUPPH) and Spiritual Attitude and Involvement List (SAIL). Results:The total score of cancer health literacy, self-management self-efficacy and spiritual attitude among female breast patients in this group was 84.63 (75.00, 97.00), 97.30(85.25, 112.00) and 105.00(96.00, 118.00) points. There was a positive correlation between cancer health literacy and self-management efficacy ( r=0.524, P<0.01) and spiritual attitude ( r=0.501, P<0.01). Multiple linear regression analysis showed that education level, average monthly family income, self-management efficacy and spiritual attitude were the influencing factors of cancer health literacy of female breast cancer patients ( t values were 2.86 to 5.91, all P<0.05), which explained 45.7% of the total variation. Conclusions:The cancer health literacy of female patients with breast cancer is at a medium level. Nursing staff can improve the self-management efficacy and spiritual attitude of female patients with breast cancer, so as to improve the level of cancer health literacy and quality of life of patients, and then alleviate the pain of patients.

Objective:To investigate the association between relative mitochondrial DNA copy number (mtDNA-CN) and coal-burning-borne endemic fluorosis (abbreviated as coal-burning-borne fluorosis).Methods:From June 2018 to March 2019, using cross-sectional study, 482 patients with coal-burning-borne fluorosis were selected as the case group in Bijie City, a typical coal-burning-borne fluorosis area of Guizhou Province; meanwhile, 212 healthy individuals from Changshun County, a non-coal-burning-borne fluorosis area in Guizhou Province, were selected as the control group. Questionnaire survey and physical examination were used to collect general condition such as basic information and living habits of the two groups, peripheral venous blood samples were collected, and real-time fluorescence quantitative PCR was used to detect the relative mtDNA-CN in peripheral blood. The correlation between relative mtDNA-CN and coal-burning-borne fluorosis was analyzed by binary and unordered multi-class logistic regression.Results:There were significant differences in the body mass index (BMI), and the distribution of gender rario, marital status and education level between the control group and the case group ( t = 7.91, χ 2 = 5.11, 13.33, 34.32, P < 0.05). The relative mtDNA-CN in the control group was higher than that in the case group [median (quartile): 202 (138, 292) vs 131 (96, 217), Z = - 7.80, P < 0.001]. The results of binary logistic regression analysis [odds ratio (95% confidence interval)] showed that educational level [primary school: 0.572 (0.377 - 0.868), junior high school and above: 0.292 (0.174 - 0.493)], relative mtDNA-CN [131 - < 217: 0.265 (0.144 - 0.488), ≥217: 0.183 (0.100 - 0.335)] and BMI [1.222 (1.142 - 1.307)] were the influencing factors for the risk of coal-burning-borne fluorosis( P < 0.05). In subgroups with different BMI and educational levels, the relative mtDNA-CN was significantly negatively correlated with the risk of coal-burning-borne fluorosis( Ptrend < 0.05), and there was no interaction between mtDNA-CN and BMI and educational levels ( Pinteraction > 0.05). The results of unordered multi-class logistic regression analysis showed that the relative mtDNA-CN were significantly negatively correlated with the risk of dental fluorosis and skeletal fluorosis ( Ptrend < 0.05). Conclusion:The higher the relative mtDNA-CN, the lower the risk of coal-burning-borne fluorosis, suggesting that mtDNA-CN may be a potential biomarker of coal-burning fluorosis.

Objective:To explore the relationship between children's intelligence and urinary fluoride in Suojia Township of Miao, Yi and Hui Nationalities (referred to as Suojia Township), a coal-burning-borne endemic fluorosis area in Guizhou Province.Methods:In April 2019, 173 children aged 10 to 13 years old were selected from three schools in Suojia Township. According to whether they had dental fluorosis, the children were divided into case group ( n = 104) and control group ( n = 69). Middle segment urine samples of the children were collected and urinary fluoride level was determined by the method of ion-selective electrode. Combined Raven's Test-the Rural in China (CRT-RC2) was used for children's intelligence quotient (IQ) test. Linear regression analysis was used to observe the association between urinary fluoride and IQ, and the results were expressed by regression coefficient ( β) and 95% confidence interval ( CI). Results:Urinary fluoride level of case group was higher than that of control group [(2.14 ± 1.78) vs (1.53 ± 0.98) mg/L], and IQ was lower than that of control group [(92.33 ± 11.68) vs (100.38 ± 11.87) points], and the differences were statistically significant ( t = 2.58, 4.41, P < 0.05). The linear regression equation of urinary fluoride ( X) and IQ ( Y) of case group was Y = 96.99 - 2.86 X. For every 1 mg/L increase in urinary fluoride level, IQ decreased by 2.86 points ( β = - 2.86, 95% CI: - 5.48 - - 0.24). Conclusion:Long-term exposure to fluoride pollution from coal burning may damage children's intelligence, and children's IQ decreases with increase of fluoride level in urine.

Objective:To investigate the relationship between gene polymorphism of osteoprotegerin (OPG) and coal-burning endemic fluorosis in Guizhou Province.Methods:In 2018 and 2019, a case-control study was conducted in Bijie City, a typical coal-burning endemic fluorosis area in Guizhou Province, and 260 cases of coal-burning endemic fluorosis patients were selected as case group. According to the "Diagnostic Criteria for Endemic Skeletal Fluorosis" (WS 192-2008), the case group was divided into severe group (130 cases) and mild group (130 cases). At the same time, 130 cases without dental fluorosis and skeletal fluorosis symptoms were chosen as control group in Changshun County, a non-coal-burning endemic fluorosis area in Guizhou Province. Whole blood genomic DNA was extracted, and real-time fluorescence quantitative PCR with TaqMan-MGB probe was utilized to type the OPG gene rs2460985, rs2073618, rs6469804 and rs6993813 four single nucleotide polymorphism (SNP) loci of all samples, and genetic model analysis was performed to compare the frequency distribution of its alleles, genotypes and constructed haplotypes in control, mild and severe groups. Results:By Hardy-Weinberg equilibrium test, the genotype frequencies of the four SNP loci all reached genetic balance in control, mild and severe groups ( P > 0.05). There was a statistically significant difference in the genotype frequency of OPG gene rs6469804 locus among the three groups (χ 2 = 10.615, P < 0.05), and the difference in the genotype frequency of this locus between the control group and the severe group was statistically significant (χ 2 = 6.784, P < 0.05). The results of genetic model analysis showed that in comparison between the control group and the severe group, the optimal genetic model of rs6469804 locus was the overdominant genetic model, the frequency distribution of genotypes AA + GG and AG in the control group and the severe group was statistically significant [odds ratio ( OR) = 1.94, 95% confidence interval ( CI): 1.16 - 3.23, P < 0.05], genotype AG was a risk factor for coal-burning endemic fluorosis. In comparison between the control group and the mild group, the optimal genetic model of rs2073618 locus was the recessive genetic model, the frequency distribution of genotypes GG + GC and CC in the control group and the mild group was statistically significant ( OR = 3.17, 95% CI: 1.08 - 9.30, P < 0.05), genotype CC was a risk factor for coal-burning endemic fluorosis. In comparison between the control group and the mild group, haplotypes C-C-G-T and T-G-A-C were risk factors for coal-burning endemic fluorosis (adjusted OR = 2.41, 1.98, 95% CI: 1.29 - 4.50, 1.22 - 3.23, P < 0.05); in comparison between the control group and the severe group, haplotype T-G-A-C was a risk factor for coal-burning endemic fluorosis (adjusted OR = 1.87, 95% CI: 1.14 - 3.07, P < 0.05). Conclusion:OPG gene rs6469804 locus genotype AG and rs2073618 locus genotype CC may be risk factors for coal-burning endemic fluorosis.

Objective To compare the antibacterial activity in vitro of Haizhengmeite and Mepem. Methods Four hundreds and eighteen bacteria isolated were collected from clinical settings in different area,including 104 strains of Escherichia coli(52 strains of ESBLs +and 52 strains of ESBLs -), 104 strains of Klebsiella pneumonia(52 strains of ESBLs +and 52 strains of ESBLs -),56 strains of Proteus spp. (28 strains of ESBLs +and 28 strains of ESBLs -), 52 strains of other Enterobacteriaceae, 51 strains of Acinetobacter baumanii and 51 strains of Pseudomonas aeruginosa.Two pharmaceutical products of meropenem injection were Mepem from Japan Sumitomo Pharmaceuticals Co., Ltd and Haizhengmeite from Zhejiang Haizheng Pfizer pharmaceuticals Co.Ltd in China, respectively.Minimum inhibitory concentrations(MIC)of two products of meropenem were determined by broth microdilution method and agar dilution method according to the Clinical and Laboratory Standards Institute(CLSI,2016).Results The sensitive rates of Escherichia coli, Klebsiella pneumoniae, and Proteus spp.to Haizhengmeite and Mepem were >85%,while the rates of the sensitivity to Acinetobacter baumanii and Pseudomonas aeruginosa were lower,with the rates of 33.3%,31.4% and 58.8%,52.9%,respectively.Conclusions Haizhengmeite and Mepem both show good antibacterial activity against Enterobacteriaceae, but lower activity against Acinetobacter baumanii and Pseudomonas aeruginosa.Both products are stable to ESBLs,and no significant difference is observed between the two products in antibacterial activity in vitro.

Objective To investigate the mechanism and epidemiological characteristics of carbap-enem-resistant Proteus mirabilis ( PM) strains deficient in swarming motility. Methods PM strains were isolated from Hangzhou General Hospital of CAPF ( Chinese People′s Armed Police Forces) during January 2013 to December 2014. Bacterial motility and flagella of the PM strains were observed through semi-solid agar culture and flagella staining. Pulsed-field gel electrophoresis ( PFGE) was performed for homology anal-ysis. Antimicrobial susceptibility test and phenotypic confirmatory test were also carried out. PCR analysis and DNA sequencing were performed to confirm the genotype of resistant genes. Plasmid electroporation and S1-PFGE in combination with Southern blot hybridization were used to determine the location of the carbap-enem-resistant genes. Genetic structure of the blaKPC-2 gene was obtained by PCR mapping. Results A total of 42 PM isolates deficient in swarming motility were screened out and the resistance rates to imipenem and meropenem were 57. 1% and 52. 4%, respectively. PCR analysis and DNA sequencing confirmed that 24 carbapenem-resistant PM isolates deficient in swarming motility carried blaKPC-2 gene and belonged to three clones as indicated by the results of PFGE. Southern blot hybridization indicated that the blaKPC-2 gene was located on plasmids varying in size (26 kb, 55 kb and 139 kb). In addition, some of the strains harbored several resistant genes, such as blaTEM-1 , blaCTX-M-65 and rmtB. The genetic structures of strains carrying blaKPC-2 gene were ISKpn8, blaKPC-2 and ISKpn6-like from upstream to downstream. Conclusion Compared with the PM strains with swarming motility, the carbapenem-resistance rate was significantly higher in these PM strains deficient in swarming motility. Carbapenemases KPC-2 played an important role in the carbapen-em-resistant PM strains deficient in swarming motility. There was a cloning spread trend for carbapenem-re-sistant PM strains in our hospital. Clinicians should pay more attention to the risk of spreading.

Objective To investigate the possible pathological role of mitochondrial apoptosis pathways and its factors in fluorosis-induced apoptosis of human hepatocellular carcinoma cell strain (HepG2).Methods Under the stimulation of 1,3,6 and 9 mmol/L concentrations of NaF in vitro for 24 h (n =5),while normal control group was cultured under normal condition,the cytotoxicity was measured with MTT.The mitochondrial apoptosis inducing factor (AIF) was measured at both mRNA (n =5) and protein levels (n =6),respectively,by real-time PCR and Western blotting.The mitochondrial apoptosis related factors,such as B-cells lymphoma-2 (Bcl-2),Bcl-associated X protein (Bax),cytochrome C,caspase-9 and caspase-3 were measured at protein levels (n =6).Results After treated with 0,1,3,6 and 9 mmol/L NaF for 24 h,the cell absorbance of HepG2 cells was 0.307 ± 0.031,0.333 ± 0.028,0.230 ± 0.011,0.178 ± 0.001 and 0.152 ± 0.003,respectively,and the differences were statistically significant among groups (F =82.224,P ＜ 0.01).After treated with 3 mol/L NaF for 24 h,the mRNA level of AIF was [(153.14 ± 5.41)％] which was increased compared to the control group [(100.00 ± 4.70)％,t =-4.73,P ＜0.05].Under the same condition,the protein levels of AIF,Bcl-2,cytochrome C in cytoplasm,caspase-9 and caspase-3 were (152.16 ± 47.30)％,(171.90 ± 51.52)％,(458.00 ± 19.48)％,(527.17 ± 200.67)％ and (432.70 ±64.27)％,which were increased compared to those of the control groups [(100.00 ± 48.86)％,(100.00 ± 34.44)％,(100.00 ± 116.59)％,(100.00 ± 19.58)％ and (100.00 ± 137.16)％,t =-3.80,-3.96,-15.76,-4.64,-5.06,all P ＜ 0.05],while the protein levels of Bax and cytochrome C in mitochondrion were (24.66 ± 26.04)％,(72.99 ±45.34)％,which were decreased compared to those of the control groups [(100.00 ± 44.01)％,(100.00 ± 34.14)％,t =6.35,0.68,all P ＜ 0.05].Conclusion The mitochondrial apoptosis pathway and related factors may be involved in NaF-induced cell death in HepG2 cells.

Objective To analyze the colistin heteroresistance in Pseudomonas aeruginosa strains and their in vitro susceptibility to antibiotics used in combination.Methods Two hundred and ninety-seven carbapenem-resistant Pseudomonas aeruginosa strains were selected for this study.Broth microdilution method was used to determine the minimum inhibitory concentrations of colistin and other antimicrobials against the Pseudomonas aeruginosa strains.The colistin heterogeneity of 20 colistin sensitive strains was analyzed by using population analysis profiles.The time-kill curves of 3 randomly selected colistin heteroresistant strains were used to determine the bacteriostatic activity of colistin.Chequer-board method was used to measure the combination efficacy of colistin with other antimicrobials including imipenem,meropenem,biapenem,ceftazidime,levofloxcin,piperacillin/tazobactam and cefoperazone/sulbactam.Results The colistin sensitive Pseudomonas aeruginosa strains accounted for 99.66％ of the 297 isolates.Population analysis profiles displayed that 35％ of the 20 isolates were colistin heteroresistant and 20％ of the 20 isolates were heterogeneous.It showed that when colistin was used in combination with other drugs,they mainly had synergistic and additive effects on heteroresistant isolates,but additive and indifferent effects on non-heterogeneous isolates.Conclusion Multidrug resistant Pseudomonas aeruginosa strains were highly susceptible to colistin,but heteroresistant and heterogeneous strains were common.The efficacy of colistin against heteroresistant isolates could be enhanced by using in combination with other drugs.
