Objective To investigate the public health issues associated with the follow-up outcomes of mental health in elderly community residents with a focus on mild cognitive impairment （MCI） and emotional problems （anxiety and depression）， as the burden of various diseases increases with global population growth and aging. Methods In this study， Patient Health Questionnaire-9， Early Dementia Screening Scale， Montreal Cognitive Assessment， Generalized Anxiety Disorder Scale， Geriatric Depression Scale， and Activities of Daily Living scale were used to analyze the data on MCI and emotional problems among the elderly in a district of Shanghai， China. The t-test， Spearman correlation analysis， and linear regression analysis were used to identify related protective factors and evaluate the effectiveness of comprehensive intervention measures. Results The first session of intervention led to an improvement in cognitive impairment （P<0.001）. During the first session of intervention， exercise and skill training were very effective in improving cognitive impairment （r=0.71 and 0.68， P<0.001）， while group instruction and the distribution of educational materials failed to achieve an ideal effectiveness. The second session of intervention also had a significant effect on cognitive impairment （P<0.05）； however， the second session of intervention lacked a significant overall effect， and skill training remained the most effective intervention method （Pr=0.0344， P<0.05）. The research findings showed that the two sessions of community intervention were protective factors against MCI and depression， while they could not alleviate anxiety. Conclusion This study validates the effectiveness of follow-up intervention measures in improving cognitive function in elderly patients with MCI， which provide scientific prediction and reference for early screening， prediction， and follow-up intervention of elderly dementia and MCI at the community level.

OBJECTIVE: Surgical wounds that can’t complete primary healing three weeks after surgery are called postoperative refractory wounds. Postoperative refractory wounds would bring great physical and life burdens to the patients and seriously affect their quality of life. To investigate the effect of platelet fibrin plasma (PFP) on postoperative refractory wound healing.APPROACH: The composition of PFP was analyzed using blood routine and blood biochemicals. Clinical data were collected that met the inclusion criteria after treatment with PFP, and the efficacy of PFP was evaluated by wound healing rate and days to healing. Next, growth factor content in PFP, PRP, and PPP was analyzed using ELISA, and PFP-treated cells were applied to investigate the effect of PFP on fibroblast and endothelial cell function. RESULTS: PFP component analysis revealed no statistical difference between platelet concentration in PFP and physiological concentration. Clinical statistics showed that PFP treatment was effective in the postoperative refractory wound (four-week wound healing rate [ 90%), significantly better than continuous wound dressing. Meanwhile, our result also proved that PFP treatment significantly enhanced vascularization by upregulated the expression level of CD31 and improved granulation tissue thickness. Activated PFP, PRP, and PPP could continuously release growth factors in vitro and the amount of growth factors released by PRP and PFP was significantly higher than PPP. In vitro studies demonstrated that active PFP could improve cell proliferation, migration, adhesion, and angiogenesis in fibroblasts and endothelial cells.INNOVATION: Physiologically concentrated platelet plasma promoted wound healing and improved related cellular functions. The modified PFP (responsible for accelerating wound healing and enhancing the migration and proliferation of fibroblasts and endothelial cells) was prepared and analyzed for its clinical effectiveness in postoperative refractory wounds. CONCLUSION Physiologically concentrated platelet plasma promoted wound healing and improved related cellular functions. The preparation of PFP could significantly reduce the amount of prepared blood, with a good application value for postoperative wounds. PFP can be considered a treatment option, especially for postoperative refractory wounds.

OBJECTIVE To explore the pharmaceutical care of reactivating anthracycline chemotherapy in patients with advanced breast cancer complicated with thyroid cancer. METHODS Clinical pharmacists participated in the whole treatment process of a patient with advanced breast cancer complicated with thyroid cancer and provided personalized medication recommendations. Considering that the patient currently has multiple primary anti-tumor drug resistance， clinical pharmacists recommend reactivating the EC rescue protocol （intravenous infusion of epirubicin hydrochloride 140 mg+cyclophosphamide 1 g， d1， 21 days for a cycle）. The cumulative lifetime dose of epirubicin and the optimal course of chemotherapy was estimated according to the body weight change of the patient. Given the issue that abnormal fluctuation of thyroid stimulating hormone （TSH） level during chemotherapy may increase the risk of cardiac toxicity， clinical pharmacists suggest adopting a dose adjustment strategy of “fast first and slow later” for Levothyroxine sodium tablet according to the target range of TSH and test results. RESULTS The doctors adopted the pharmacists’ suggestion； the clinical pharmacists assisted the doctors in reactivating the anthracycline-based 7-cycle combination regimen， during which the patient had no significant cardiac adverse events and was repeatedly evaluated as stable. TSH decreased steadily after Levothyroxine sodium tablets were added， and no adverse reaction related to TSH inhibition was observed. CONCLUSIONS Patients with primary drug-resistant breast cancer complicated with thyroid cancer may be reactived anthracyclines if necessary， but baseline cardiac function and thyroid hormone levels should be tested before initiation， and cardiac toxicity risk assessment should be performed in combination with the patient’s history. Clinical pharmacists should actively exert their professional advantages to carry out whole-process pharmaceutical care for such patients， so as to ensure the safety of drug use for patients.

The aim of this study was to prepare a high drug-carrying capacity micellar drug delivery system(CTD@Sol)of the polymer zebra tetracycline and to preliminarily investigate the feasibility of this drug delivery system for the treatment of breast cancer.Firstly,CTD@Sol was prepared using sol as the carrier material and CTD as the model drug,and its pharmacological properties such as appearance and morphology,particle size,potential and in vitro release were evaluated.The growth inhibitory and apoptotic effects of CTD@Sol on breast cancer(4T1)cells were investigated by MTT assay and Annexin V-FITC/PI double staining assay;the uptake efficiency of 4T1 to this delivery system was investigated by flow cytometry;and the in vivo tissue distribution of the delivery system and the targeting of tumour tissues were investigated by small animal in vivo imaging technique.The results showed that CTD@Sol appeared as a light pale blue creamy white colour,with an average particle size of(159.73±1.96)nm,a PDI of 0.198±0.006,Zeta potential of-(47.60±1.77)mV,an encapsulation rate of(90.29±1.69)%and a drug loading capacity of(45.00±0.84)%;the in vitro release and haemolysis experiments showed that the drug release rate of CTD@Sol in acidic environment(pH 5.5)was significantly faster than that in neutral environment(pH 7.4),suggesting that the system is acid-sensitive and has good biosafety under endocytosed pH conditions.Cellular uptake,cytotoxicity and apoptosis experiments showed that CTD@Sol was more lethal to 4T1 cells,and the sol-gel polymer micelles as a drug delivery vehicle could significantly improve the cellular uptake efficiency of the drug;in vivo experiments showed that the delivery system had a significant targeting effect on tumour tissues.In conclusion,this study has successfully produced a CTD@Sol drug delivery system with high drug loading capacity(>45%),good pharmacological performance,strong targeting and biosafety,which has the potential to be used in the treatment of breast cancer.

Objective:To explore the application value of four-dimensional automatic left ventricular quantitation(4D Auto LVQ) technology, in evaluating the myocardial mechanics in patients with different risk stratifications of hypertrophic cardiomyopathy(HCM).Methods:A total of 88 HCM patients and 20 healthy volunteers were selected from February 2020 to February 2022 in the First Affiliated Hospital of Zhengzhou University. According to the HCM Risk-SCD score, HCM patients were divided into 3 groups: low-risk group( n=49), intermediate-risk group( n=21), and high-risk group( n=18). Conventional ultrasound parameters were collected, and 4D Auto LVQ technology was used to obtain the mechanical parameters of left ventricular myocardium, including global longitudinal strain(GLS) , global circumferential strain(GCS), global area strain(GAS), global radial strain(GRS), twist and torsion. The differences in these parameters among the four groups were compared. The predictive values of conventional ultrasound parameters and myocardial mechanical parameters in patients with intermediate- and high-risk HCM patients were analyzed by ROC curve. Results:①Left ventricular end-diastolic diameter, left ventricular end-diastolic volume, left ventricular end-systolic volume, and peak systolic velocity of mitral annulus in the low-, intermediate-, and high-risk groups were lower than those in the control group while left ventricular maximal wall thickness(LVMWT) and early diastolic peak velocity of mitral value orifice/early diastolic peak velocity of mitral annulus(E/e′) were higher, left atrial diameter(LAD) and left ventricular outflow tract gradients(LVOTG) in the intermediate- and high-risk groups were higher than the low-risk group(all P<0.05). ②Compared with the control group, the GLS of HCM patients was lower, and the GLS of the intermediate- and high-risk groups was lower than the low-risk group. GCS and GRS in the intermediate- and high-risk groups were lower than those in the low-risk group. GAS in the high-risk group was lower than the low-risk and the control group, but higher than the intermediate-risk group(all P<0.05). Compared with the control group, the twist and torsion in the intermediate- and high-risk groups were higher, but lower than the low-risk group, and the differences were statistically significant(all P<0.05). ③The ROC results showed that the area under the curve(AUC) of the model containing conventional ultrasound parameters(LVWMT, LAD, and LVOTG) for predicting intermediate- and high-risk HCM patients was 0.811, with a sensitivity of 0.769 and a specificity of 0.755. The AUC of the conventional ultrasound parameters combined with myocardial mechanical parameters was 0.904, as the sensitivity was 0.667 and the specificity was 0.980. Conclusions:4D Auto LVQ can evaluate the mechanical characteristics of LV myocardium in HCM patients with different risk stratifications. Myocardial mechanical parameters combined with conventional ultrasound parameters can improve the diagnostic performance of patients with intermediate- and high-risk HCM.

Objective To investigate the expression of Member RAS Oncogene Family(RAB10)in pancreatic cancer(PAAD)and its effects on the proliferation,migration,invasion and apoptosis of SW1990 cells(human pancreatic cancer cells).Methods The expression of RAB1 0 mRNA in PAAD tissues wasanalyzed by the cancer gene database GEPIA(Gene Expression Profiling Interactive Analysis)and TCGA(The Cancer Genome Atlas).Cox regression analysis was used to detect relationship between RAB10 mRNA expression and the prognosis of pan-creatic cancer patients.We targeted small interfering RNA(R4B10-siRNA)targeting RAB10 as the silence group,and constructed an overexpression plasmid(RAB10-OE)for overexpression of RAB10 as the overexpression group.The effects of silencing and overexpressionweredetected by Q-PCR;protein expression levelsweredetected by West-ern blot.EdUcellproliferation test,wound healing test,Transwelltestand flow cytometry test were used to determine the effects of RAB10 on the proliferation,migration,invasion and apoptosis of SW1990 pancreatic cancer cells.Re-sults RAB10 mRNA expression in PAAD tissues was higher than that innormal pancreatic tissues(P＜0.05).The results of EdUcellproliferation testshowed that the proliferation rate of SW1990 cells in the RAB10-OE group was higher thanthat in the control group,and the proliferation rate of SW1990 cells in the RAB10-siRNA group was lower than that inthe control group(P＜0.05).The results of the Transwell test and wound healing test showed that the invasion rate and mobility rate of RAB10-OE group were higher thanthose of the control group,and the mobility and invasion rate of RAB10-siRNA group were lower than those of the control group(P＜0.05).The re-sults of flow cytometry test showed that the apoptosis rate was lower in the RAB10-OE group than the control group,and the apoptosis rate in the RAB10-siRNA group was higher than the control group(P＜0.05).The median sur-vival time of RAB10 high expression group was significantly lower than that of RAB10 low expression group(P＜0.05).Cox regression analysis showed that clinical grade,T stage,M stage and RAB10 mRNA expression were re-lated to survival and prognosis of pancreatic cancerpatients(P＜0.05).Multivariate Cox regression analysis showed that the expression level of RAB10 mRNA was the independent risk factor affecting the prognosis of pancre-atic cancer patients(P＜0.05).Conclusion RAB10 is highly expressed in PAAD tissues and RAB10 can pro-mote the proliferation of pancreatic cancer cells,accelerate the ability to invade and migrate,and inhibit the apop-tosis of pancreatic cancer cells.RAB10 is an independent risk factor for survival prognosis in patients with pancreat-ic cancer.
