Objective: To explore the causal link of cumulative ecological risk and future orientation with health risk behaviors among higher vocational college students, so as to provide reference for reducing and preventing health risk behaviors among higher vocational college students. Methods: A longitudinal follow up study was conducted on 612 students using convenience sampling from 2 vocational colleges in Hunan Province. The Cumulative Ecological Risk Scale, Future Orientation Scale, and Health Risk Behavior Scale were used during three follow up visits (T1: September 2022, T2: June 2023, T3: March 2024), and a cross lagged panel model was constructed to examine the longitudinal causal relationship of cumulative ecological risk, future orientation and health risk behaviors. Analysis of longitudinal intermediary effect between variables by Bootstrap. Results: The cumulative ecological risk scores of T1, T2 and T3 among higher vocational college students were (2.94±1.44,2.99±1.63,3.02±1.54), future orientation scores (40.49±4.71,41.51±5.72,41.06±4.35) and health risk behavior scores (3.73±2.01,3.49±2.00,3.23±2.00). The results of repeated measures ANOVA showed that the future orientation score of T2 was higher than that of T1, and the main effect of measurement time was statistically significant ( F=5.09，P＜0.01,η 2=0.02). The health risk behavior score of T1 was higher than that of T2, and the health risk behavior score of T2 was higher than that of T3, and the main effect of measurement time was statistically significant ( F=10.12，P＜0.01,η 2=0.03).The cross lagged model showed good adaptability, with χ 2/df =7.20 ( P <0.01), relative fitting indicators GFI=0.98, CFI=0.99, TLI=0.96, IFI=0.99, NFI =0.99, and absolute fitting indicator RMSEA =0.06. Among them, the T1, T2 cumulative ecological risk showed negatively predictive effects on T2, T3 future orientation ( β =-0.24, -0.47 ), and T1, T2 cumulative ecological risk positively predicted T2, T3 health risk behavior ( β =0.20, 0.24), while T1, T2 future orientation negatively predicted T2, T3 health risk behavior ( β =-0.25, -0.18) ( P ＜0.01). Bootstrap test analysis found that T2 future orientation had a longitudinal mediating effect ( β=0.04, P ＜0.01) on the T1 cumulative ecological risk and T3 health risk behavior. Conclusions The accumulation of ecological risk among higher vocational college students can positively predict health risk behaviors, while future orientation can negatively predict healthrisk behaviors. Moreover, future orientation plays a longitudinal mediating role between accumulated ecological risks and health risk behaviors.

OBJECTIVE: The aim of this study is to explore the clinical efficacy and safety of endocrinotherapy combined with Shenqi Pills on hormone-sensitive prostate cancer (HSPC). METHODS: Eighty patients who were diagnosed with HSPC and renal-yang deficiency at the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine and the Hospital of Traditional Chinese Medicine of Mayang Miao Autonomous County from 1st April 2021 to 30th April 2024 were randomly divided into 2 groups. The patients in the control group were treated with androgen deprivation therapy (ADT). And the patients in treatment group were treated with Shenqi Pills orally on the basis of the control group. The baseline data of the two groups were analyzed. After 36 months of treatment, the differences between the two groups were compared in terms of overall survival (OS), prostate-specific antigen (PSA) level, PSA response rate, Functional Assessment Scale for Prostate Cancer Therapy (FACT-P), Chinese medicine evidence scores, testosterone level and safety. RESULTS: A total of 80 study subjects were included in this study, including 42 cases in the treatment group and 38 cases in the control group. There was no statistical difference in the baseline data between the two groups before treatment (P>0.05). At the end of the observation period, a statistically significant difference in OS was found in the treatment group compared to the control group in the subgroup of patients with a disease duration ranged of 0-6 months (P<0.05). There was no statistically significant difference in PSA levels in the treatment group at 3 months (P>0.05). And the differences in the proportion of PSA50 (98.1% vs 91.4%), PSA90 (92.9% vs 84.6%) and the proportion of decrease in PSA (56.7% vs 33.8%) in the treatment group were found compared to those in the control group after 6 months of tre atment. After 12 months of treatment, the scores of FACT-4 and renal-yang deficiency in the treatment group were (95.28±7.93) and (15.73±5.70) respectively, compared to the scores in the control group (［85.46±10.12］ and ［18.20±4.27］ (P<0.05). However, there was no significant difference in serum testosterone (［0.60±0.24］ nmol/L vs ［1.09±2.10］ nmol/L) between the two groups (P>0.05). After 24 months of treatment, there were significant differences in in the FACT-4 total score (［97.95±7.54］ vs ［80.33±8.58］), renal-yang deficiency syndrome score (［14.64±5.15］ vs ［24.94±8.75］) between the treatment group and the control group (P<0.05). However, there was no significant difference in serum testosterone ( ［0.73±1.01］ nmol/L vs ［0.59±0.25］ nmol/L) between the two groups (P> 0.05). Better therapeutic results were showed in the treatment group in terms of total FACT-P score, physical situation score, social and family situation score, emotional state score, functional state score, additional score and renal-yang deficiency symptom score (P<0.05). After treatment, there was no serious adverse reaction in the course of treatment, and no obvious abnormality was found in the liver and kidney function of the patients from two groups. CONCLUSION Endocrinotherapy combined with Shenqi Pills is safe and effective in HSPC and can reduce the risk of death in HSPC patients, and the earlier the intervention, the longer the overall survival of the patients. In addition, this treatment regimen can increase the PSA response rate, improve patients' quality of life, and reduce the renal-yang deficiency syndrome score without the risk of elevating serum testosterone levels.

BACKGROUND:Numerous scholars have previously researched certain greater tuberosity fractures and the procedures used to treat them.Few researchers,however,have studied the comminuted split fracture of the greater tuberosity of the humerus(Liu-Gang type IV)with rotator cuff tear in great detail. OBJECTIVE:To compare the clinical therapeutic effect of open repair position modified calcaneal plate combined with suture anchors and proximal humeral internal locking system(PHILOS)plate in the treatment of comminuted fracture of split-type greater tuberosity of humerus combined with rotator cuff tears(Liu-Gang type IV). METHODS:Case data of 30 patients with comminuted fracture of split-type greater tuberosity of humerus combined with rotator cuff tears(Liu-Gang type IV)from May 2012 to May 2022 were retrospectively analyzed.They were divided into the modified calcaneal plate combined with suture anchor group(group A)and the PHILOS with#2 Johnson group(group B),with 15 cases in each group.Intraoperative blood loss,surgical time,and incision length of all patients were recorded.Pain visual analog scale score,Constant-Murley score,as well as shoulder joint abduction,forward flexion,external rotation,and dorsal expansion activities during the last follow-up(>1 year)were evaluated. RESULTS AND CONCLUSION:(1)The surgical incision length and operation time were shorter,and blood loss was less in group A than those in group B(P<0.05).(2)No significant difference in visual analog scale score and Constant-Murley score was detected between the two groups(P>0.05).(3)During the last follow-up,forward flexion in group A was better than that in group B(P<0.05).No significant difference in abduction,external rotation,and dorsal expansion was determined between group A and group B(P>0.05).(4)In terms of complications,there was 1 case of shoulder joint pain and discomfort in group A(7%),2 cases of subacromial impingement syndrome,2 cases of upward movement of nodules,and 2 cases of shoulder joint pain(40%)in group B.There were significant differences in complication rates between the two groups(P=0.031).(5)In summary,the modified calcaneal plate combined with suture anchors in the treatment of comminuted fracture of split-type greater tuberosity of humerus combined with rotator cuff tears(Liu-Gang type IV)could better restore the forward flexion function of the shoulder joint and has a small incision,less blood loss,shorter operation time and fewer complications.

Objective To observe the effect of coronary reperfusion therapy on the differential ex-pression of plasma exosomal miRNAs in patients with acute myocardial infarction(AMI).Meth-ods Three elderly male AMI patients undergoing coronary reperfusion therapy in our hospital from October to November 2022 were recruited in this study.The venous blood samples were col-lected at admission and 2 and 24 h after recanalization.MiRNA-sequencing was used to screen the differentially expressed miRNAs which were commonly expressed in the plasma exosomes of the 3 patients.Bioinformatics analysis was performed on the target genes,and then the differentially expressed miR-499a-5p was verified by qPCR.Results Compared with the plasma exosomal miRNAs at admission,there were 418 up-regulated and 406 down-regulated miRNAs at 2 h after operation,and 320 up-regulated and 225 down-regulated miRNAs at 24 h after operation(P＜0.05);Compared with the miRNAs at 2 h after operation,there were 344 up-regulated and 350 down-regulated ones at 24 h after operation(P＜0.05).Kyoto Encyclopedia of Genes and Ge-nomes enrichment analysis showed that the differentially expressed miRNAs were enriched in phosphatidylinositol-3-kinase-protein kinase B,hypoxia-inducible factor 1,and vascular smooth muscle contraction pathways.Gene Ontology analysis indicated that the molecular functions of dif-ferentially expressed miRNA target genes were mainly enriched in protein binding and DNA bind-ing;cellular components were mainly enriched in cell membrane and cytoplasm;and biological processes were mainly enriched in signaling and transcription of DNA templates.The miR-499a-5p level was significantly lower at 2 h postoperatively than at admission[(0.577±0.020)vs(1.000± 0.023),P＜0.05],and at 24 h postoperatively than at 2 h postoperatively[(0.068±0.006)vs(0.577±0.020),P＜0.05].Conclusion Plasma exosomal miRNAs can be used as a biomarker for early diagnosis of elderly AMI patients and for predicting the efficacy of reperfusion therapy.

Objective:To observe the clinical effect of lower eyelid blepharoplasty combined with micro-autologous fat transplantation (MAFT) in the rejuvenation of the infraorbital regions.Method:A retrospective analysis was conducted on the clinical data of patients with lower eyelid pouch and tear trough treated with lower eyelid blepharoplasty combined with MAFT in the Department of Plastic Surgery of Affiliated Hospital of Nanjing University of Chinese Medicine from March 2020 to March 2022. Patients seeked medical attention due to lower eyelid pouch and tear trough, with or without skin laxity, and some patients had varying degrees of midface depression. After preoperative examination and evaluation of the patient’s infraorbital area and midfacial depression, appropriate individualized plans were developed.The patient underwent lower eyelid blepharoplasty by transconjunctival approach combined with tear trough MAFT. For patients with low or depressed midface, midface MAFT was also performed, and for patients with skin laxity, skin removal surgery was performed simultaneously. Complications were recorded after the operation. Preoperative and postoperative photos of more than 6 months were taken with the same postion and delivered to the same doctor to grade the patient’s Barton classification (0-3 grades, with higher grade indicating more obvious tear trough deformity). The improvement of tear trough deformity after surgery was assessed, and the global aesthetic improvement scale (GAIS) score was also assessed. The patients evaluated their improvement using the patients aesthetic improvement scale (PAIS) score (GAIS and PAIS are both 1-5 points, with higher scores indicating more significant postoperative improvement). Normal distribution metric data was represented by Mean±SD, and count data was represented by frequency and/or percentage; skewed distribution metric data was represented by M ( Q1, Q3), and compared by rank sum test. Results:A total of 69 patients were enrolled, including 9 males and 60 females, aged 25-45 years, with an average age of 36.7 years. Among them, 35 patients had midfacial depression, and 11 patients had skin laxity. (0.37±0.07) ml (0.2-0.6 ml) of micro-autologous fat was injected into the orbicularis oculi muscle on each side; (0.18±0.06) ml (0.1-0.2 ml) of micro-autologous fat was injected into the subcutaneous layer on each side; (3.80±0.98) ml (3-5 ml) of micro-autologous fat was injected into the deep medial cheek fat compartment and pyriform aperture fat compartment on each side. No serious complications occurred after the surgery. Postoperative follow-up lasted for 6-13 months, with an average of 8.7 months. The patient’s lower eyelid pouch, tear trough deformity, and depression in the midface have all improved, presenting a youthful and smooth appearance from the infraorbital area to the midface. The skin texture in the lower eyelid area had also improved. At the last follow-up, the Barton classification of the lacrimal groove decreased compared with that before surgery, and the difference was statistically significant [grade 0 (0, 1) vs. grade 2 (1, 2), Z=-7.62, P<0.001]. At the last follow-up, the PAIS score of 69 patients was 5 points in 49 cases (71%) and 4 points in 20 cases (29%); doctor’s GAIS score was 5 points in 38 cases (55%), 4 points in 27 cases (39%), and 3 points in 4 cases (6%) . Conclusion:For those patients with aging status of infraorbital region, like lower eyelid pouch and tear trough deformities, the combination of lower eyelid blepharoplasty through the transconjunctival approach and MAFT can achieve good therapeutic effects. This method is safe with a short recovery time.

Objective:To analyze the disease burden in middle-aged and elderly population aged ≥55 in Shenzhen from 2016 to 2030 and provide evidence for the development of healthy aging strategies.Methods:The years of life lost (YLL), years lost due to disability (YLD), and the disability-adjusted life year (DALY) in this population from 2016 to 2022 were calculated. Joinpoint log-linear regression model was used to analyze the time trend. Bayesian age-period-cohort model and grey system model were used to predict YLL, YLD, and DALY in this population in 2030.Results:From 2016 to 2022, the crude DALY rate showed a transient fluctuation in age group 55-74 years, but a pronounced increase in age group ≥85 years. The proportions of YLL and YLD due to non-communicable diseases in all age groups was considerably higher than those due to communicable and nutritional diseases and injuries. In 2022, in all age groups, the YLL due to neoplasms (55-74 years old) and cardiovascular disease (≥75 years old) ranked first, and the YLD due to musculoskeletal disorder ranked first. By 2030, the causes of YLL and YLD ranking first in each age group would be remained, while the ranks of some causes would increase.Conclusions:The age specific characteristics of current and predicted disease burden differed in individuals aged ≥55 years. Therefore, it is necessary to allocate social and medical resources according to the disease burden pattern.

OBJECTIVE To explore the effect of Tuoli Xiaodusan(MDX)on ischemia-reperfusion injury of rat skin flaps and its potential mechanism.METHODS Rats were randomly divided into sham operation group(Sham group),Model group,MDX high-dose group(MDX-H group)and MDX low-dose group(MDX-L group),with 10 rats in each group.After the rat back skin flap model was successfully constructed,the drug was administered by gavage immediately,once a day for 14 consecutive days.The changes of rat skin flaps in each group after surgery were observed,and the survival rate of rat skin flaps in each group was measured on the 14th day after surgery;the histopathological changes of rat skin flaps were observed by HE staining;the protein expression of p-p65 and p-IκBα in the rat skin flap tissue was detected by Western blot;ELISA method was used to detect the expression of TNF-α,IL-1β,and IL-6 cytokines;Ki67 and CD31 immunohistochemical staining were used to observe epidermal basal layer cell prolifera-tion and vascular regeneration.RESULTS Compared with Model group,MDX-H group and MDX-L group had a small amount of e-dema and inflammatory fluid exudation after surgery,and the scab removal time was advanced;the ischemic necrosis of the skin flap was significantly improved,the area of skin flap necrosis was significantly decreased,and the survival rate of rat skin flaps was signifi-cantly increased(P<0.01).In addition,MDX could significantly improve the pathological morphology of ischemia-reperfusion injury in rat back skin flaps,reduce the expression of p-p65 and p-IκBα proteins(P<0.001),and decrease the levels of TNF-α,IL-1β,IL-6 inflammatory factor levels(P<0.05,P<0.01,P<0.001,P<0.000 1).The differences in Ki67 and CD31 also suggested that treatment with MDX accelerate re-epithelialization and blood vessel formation after ischemic flap injury.CONCLUSION MDX plays a role in improving ischemia-reperfusion injury of skin flaps by regulating the NF-κB signaling pathway and accelerating epithelializa-tion and angiogenesis.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective To investigate the distribution and antimicrobial resistance profiles of the common pathogens isolated from urine from 2015 to 2021 in the CHINET Antimicrobial Resistance Surveillance Program.Methods The bacterial strains were isolated from urine and identified routinely in 51 hospitals across China in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Antimicrobial susceptibility was determined by Kirby-Bauer method,automatic microbiological analysis system and E-test according to the unified protocol.Results A total of 261 893 nonduplicate strains were isolated from urine specimen from 2015 to 2021,of which gram-positive bacteria accounted for 23.8％(62 219/261 893),and gram-negative bacteria 76.2％(199 674/261 893).The most common species were E.coli(46.7％),E.faecium(10.4％),K.pneumoniae(9.8％),E.faecalis(8.7％),P.mirabilis(3.5％),P.aeruginosa(3.4％),SS.agalactiae(2.6％),and E.cloacae(2.1％).The strains were more frequently isolated from inpatients versus outpatients and emergency patients,from females versus males,and from adults versus children.The prevalence of ESBLs-producing strains in E.coli,K.pneumoniae and P.mirabilis was 53.2％,52.8％and 37.0％,respectively.The prevalence of carbapenem-resistant strains in E.coli,K.pneumoniae,P.aeruginosa and A.baumannii was 1.7％,18.5％,16.4％,and 40.3％,respectively.Lower than 10％of the E.faecalis isolates were resistant to ampicillin,nitrofurantoin,linezolid,vancomycin,teicoplanin and fosfomycin.More than 90％of the E.faecium isolates were ressitant to ampicillin,levofloxacin and erythromycin.The percentage of strains resistant to vancomycin,linezolid or teicoplanin was＜2％.The E.coli,K.pneumoniae,P.aeruginosa and A.baumannii strains isolated from ICU inpatients showed significantly higher resistance rates than the corresponding strains isolated from outpatients and non-ICU inpatients.Conclusions E.coli,Enterococcus and K.pneumoniae are the most common pathogens in urinary tract infection.The bacterial species and antimicrobial resistance of urinary isolates vary with different populations.More attention should be paid to antimicrobial resistance surveillance and reduce the irrational use of antimicrobial agents.
