ObjectiveTo construct a group-based trajectory model (GBTM) for early medication adherence check-in, and to analyze the relationship between different trajectories and treatment outcomes in tuberculosis patients using data that were generated from smart tools for monitoring their medication adherence and check-in. MethodsFrom October 1, 2022 to September 30, 2023, a total of 163 pulmonary tuberculosis patients diagnosed in Fengxian District were selected as the study subjects. The GBTM was utilized to analyze the weekly active check-in trajectories of the subjects during the first 4 weeks and establish different trajectory groups. The χ² tests were employed to compare the differences between groups and logistic regression analysis was conducted to explore the relationship between different trajectory groups and treatment outcomes. ResultsA total of four groups were generated by GBTM analyses, of which a low level of punch card was maintained in group A, 6% of the drug users increased rapidly from a low level in group B, 17% of drug users increased gradually from a low level in group C, and 18% of drug users maintained a high level of punch card in group D. The trajectory group was divided into two groups according to homogeneity, namely the low level medication punch card group (group A) and the high level medication punch card group (group B, group C, and group D). The results of multivariate logistic regression analyses revealed that low-level medication check-in (OR=3.250, 95%CI: 1.089‒9.696), increasing age (OR=1.030, 95%CI: 1.004‒1.056), and not undergoing sputum examination at the end of the fifth month (OR=2.746, 95%CI: 1.090‒7.009) were significantly associated with poor treatment outcomes. ConclusionThe medication check-in trajectory of pulmonary tuberculosis patients within the first 4 weeks is correlated with adverse outcomes, or namely consistent low-level medication adherence check-ins are associated with poor treatment outcomes, while high-level medication adherence check-ins are associated with a lower incidence of adverse outcomes.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Objective To observe the effects of different frequencies of electroacupuncture on the degree of atrophy of quadriceps femoris in rabbits with anterior cruciate ligament(ACL)injury model;To explore the possible mechanisms of electroacupuncture in treating ACL injury.Methods Totally 24 New Zealand rabbits were randomly divided into blank group,model group,low-frequency electroacupuncture group and high-frequency electroacupuncture group,with 6 rabbits in each group.Except for the blank group,ACL injury models were established in the other groups.On the 7th day after modeling,the low-frequency electroacupuncture group and the high-frequency electroacupuncture group performed electroacupuncture treatment(continuous wave,frequency of 2 Hz and 100 Hz respectively,and left the needle in place for 20 min)at"Xuehai"and"Liangqiu"of the operation side,and the remaining groups were only grasped and immobilized,for 21 days.The mass ratio of the quadriceps femoris was calculated,the histopathological morphology of the quadriceps femoris tissue of the rabbits in each group was observed by HE staining,the expressions of NO,iNOS in quadriceps femoris tissue were detected by ELISA,the content of ROS in quadriceps femoris tissue was detected by fluorescent probe,the protein expressions of PERK,ATF6,IRE1,MuRF1,MAFbx in quadriceps femoris tissue were detected by Western blot.Results Compared with the blank group,the quadriceps femoris muscle mass ratio of the model group rabbits was significantly reduced(P<0.01),with irregular arrangement of muscle cells,accompanied by swelling and atrophy,significant interstitial edema,and extensive inflammatory infiltration,the contents of NO,iNOS and ROS in quadriceps femoris tissue significantly increased(P<0.01),while the expressions of PERK,ATF6,IRE1,MuRF1 and MAFbx proteins significantly increased(P<0.01).Compared with the model group,the quadriceps femoris muscle mass ratio in the low-frequency and high-frequency electroacupuncture groups significantly increased(P<0.01),with regular arrangement of muscle cells,improved swelling and atrophy of cells,and reduced interstitial edema and inflammation,the contents of NO,iNOS and ROS in quadriceps femoris tissue were significantly reduced(P<0.01),and the expressions of PERK,ATF6,IRE1,MuRF1 and MAFbx proteins significantly decreased(P<0.01).Moreover,the low-frequency electroacupuncture group had better effects than the high-frequency electroacupuncture group(P<0.05).Conclusion Different frequencies of electroacupuncture intervention in ACL injury rabbits can better delay the degree of quadriceps femoris atrophy,and its mechanism may be related to reducing the expressions of oxidative metabolites NO,iNOS,ROS,and reducing the expressions of endoplasmic reticulum stress-related proteins PERK,ATF6,IRE1 in quadriceps fermoris,which in turn inhibit the expressions of quadriceps atrophy factors MuRF1,MAFbx,and delaying the degradation of quadriceps muscle proteins.The effect of low-frequency electroacupuncture is superior to the high-frequency electroacupuncture.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Objective:To investigate the safety and efficacy of the TRIANGLE operation after neoadjuvant chemotherapy in locally advanced pancreatic cancer(LAPC).Methods:This study is a retrospective case series analysis. Between January 2020 and December 2022, a total of 103 patients were diagnosed as LAPC who underwent neoadjuvant chemotherapy at the Pancreas Center, the First Affiliated Hospital of Nanjing Medical University. Among them, 26 patients (25.2%) underwent the TRIANGLE operation. There were 15 males and 11 females,with a age of (59±7) years (range: 49 to 74 years). The pre-treatment serum CA19-9( M(IQR)) was 248.8(391.6)U/ml (range: 0 to 1 428 U/ml),and the serum carcinoembryonic antigen was 4.1(3.8)μg/L(range: 1.4 to 13.4 μg/L). The neoadjuvant chemotherapy regimens included: mFOLFIRINOX regimen in 6 cases(23.1%), GnP regimen in 14 cases(53.8%), and mFOLFIRINOX+GnP regimen in 6 cases(23.1%). The follow-up duration extended until June 2023 or until the occurrence of the patient′s death or loss to follow-up. The Kaplan-Meier method was employed to estimate the 1-year and 3-year overall survival rates. Results:After neoadjuvant chemotherapy,CA19-9 levels decreased by 92.3(40.1)%(range:2.1% to 97.7%). Evaluation of the response to treatment revealed 13 cases(50.0%) of stable disease,11 cases(42.3%) of partial response,and 2 cases(7.7%) of complete response. The surgical operation consisted of 12 cases(46.2%) of pancreaticoduodenectomy,12 cases(46.2%) of distal pancreatectomy,and 2 cases(7.7%) of total pancreatectomy. Margin determination was based on the “standardised pathology protocol” and the “1 mm” principle. No R2 and R1(direct) resections were observed,while the R0 resection rate was 61.5%(16/26), and the R1(1 mm) resection rate was 38.5%(10/26).The R1(1 mm) resection rates for the anterior margin,posterior margin,transected margin,portal vein groove margin,and uncinate margin were 23.1%(6/26),19.2%(5/26),12.5%(3/24),2/14, and 1/12, respectively. The overall postoperative complication rate was 57.8%(15/26),with major complications including grade B/C pancreatic fistula 25.0%(6/24,excluding 2 cases of total pancreatectomy),delayed gastric emptying in 23.1%(6/26),wound complications 11.5%(3/26),postoperative hemorrhage 7.7%(2/26), chylous fistula 7.7%(2/26) and bile fistula 3.8%(1/26). No reoperation was performed during the perioperative period(<90 days). One patient died on the 32 nd day postoperatively due to a ruptured pseudoaneurysm. A total of 25 patients were followed up,with a follow-up time of 21(24)months(range: 8 to 42 months). During the follow-up period,8 cases(32.0%) died due to tumor recurrence and metastasis,while 17 patients(68.0%) remained alive,including 11 cases of disease-free survival,5 cases of distant metastasis,and 1 case of local recurrence. The overall survival rates at 1- and 3-year after the initiation of neoadjuvant chemotherapy were 95.8% and 58.9%, respectively. The overall survival rates at 1- and 3-year after surgery were 77.7% and 57.8%, respectively. Conclusion:Performing pancreatoduodenectomy according to the Heidelberg triangle protocol in LAPC patients after neoadjuvant chemotherapy might increase the R0 resection rate without increasing perioperative mortality or the incidence of major postoperative complications.

Objective To establish a noninvasive diagnostic model for liver fibrosis in chronic hepatitis B(CHB)patients with normal alanine aminotransferase(ALT)and an age of≤30 years by selecting specific indicators from the commonly used noninvasive indicators such as clinical,biochemical,and imaging indicators,to avoid invasive liver biopsy in such patients to some extent,and to guide the timing of antiviral therapy.Methods A total of 251 CHB patients with normal ALT and an age of≤30 years who underwent liver biopsy in Shenzhen Third People's Hospital and The First Hospital of Changsha from January 2019 to January 2022 were enrolled,with 175 patients in the model group and 76 patients in the validation group,and commonly used clinical indicators were obtained based on clinical experience and related articles.The two-independent-samples t test or the two-independent-samples Mann-Whitney U rank sum test was used for comparison of continuous data between groups,and the chi-square test was used for comparison of categorical data between groups.A Spearman rank correlation analysis was used to investigate the correlation between each indicator and liver fibrosis and identify the indicators with correlation(P<0.01,r>0.200);a Logistic regression analysis was used to establish a noninvasive diagnostic model,and the receiver operating characteristic(ROC)curve was used to evaluate its performance and perform validation of the model;this model was then compared with the widely used models of aspartate aminotransferase-to-platelet ratio index(APRI)and fibrosis-4(FIB-4).The Kappa consistency test was used to investigate the consistency of pathological results.Results A total of 17 commonly used clinical indicators were obtained,among which 9 indicators(ALT,aspartate aminotransferase[AST],gamma-glutamyl transpeptidase[GGT],ferritin[FERR],platelet count[PLT],procollagen type Ⅲ amino-terminal peptide[PⅢP],collagen Ⅳ[CⅣ],HBV DNA,and spleen thickness)were correlated with liver fibrosis(P<0.01,r>0.232).Based on the above indicators,the predictive model was established as P=1/(1+e-γ),γ=-1.902+0.106×AST-0.011×PLT-0.265×HBV DNA+0.059×PⅢP,in which P was the probability for predicting≥S2 liver fibrosis and γ was the predictive index.The comparison between each indicator and the model showed that the model had the largest area under the ROC curve of 0.852,with a sensitivity of 92.7%and a specificity of 76.9%.The model was validated in 76 patients and showed an accuracy of 77.600%.The model was compared with APRI and FIB-4,and the results showed that the model has good accuracy.Conclusion Compared with the models of APRI and FIB-4 commonly used in the world,this model can more accurately judge the degree of liver fibrosis in such patients,thereby replacing liver biopsy to some extent and guiding the timing of antiviral therapy.

Lung cancer is the malignant tumor with the highest incidence and mortality rate worldwide.For lung adenocarcinoma,identifying specific gene mutations,fusions,and giving corresponding targeted drugs can greatly improve the survival time of the patients.Among them,anaplastic lymphoma kinase(ALK)fusion occurs in 3％-7％of non-small cell lung cancer(NSCLC).In clinical practice,a variety of detection methods can be used to determine the ALK fusion status,but false negative test results are possible.This paper retrospectively analyzed the diagnosis and treatment of a patient with lung adeno-carcinoma,judged the ALK fusion status by various detection methods.Among them,immunohistochemistry(IHC)(Ventana D5F3),RNA based next-generation sequencing(RNA-based NGS)confirmed positive echinoderm microtubule associated protein like 4(EML4)-ALK fusion,while DNA-based NGS was negative.This paper analyzed the detection methods of ALK fusion,in order to clarify which detection method is the most accurate and simple to choose in different clinical cases and guide the subsequent treatment.

  Objective  To evaluate the effect of intraoperative multimodal analgesia on the early postoperative quality of recovery in end-stage head and neck cancer patients undergoing open gastrostomy surgery.  Methods  This was a prospective, parallel, randomized controlled study. The research subjects were end-stage head and neck cancer patients who underwent elective open gastrostomy at Beijing Tongren Hospital affiliated to Capital Medical University from November 2022 to May 2023. The patients were randomly divided into local anesthesia group and multimodal analgesia group at a 1∶1 ratio. For local anesthesia group, 0.25% ropivacaine 20-30 mL was administered for local infiltration anesthesia. For multimodal analgesia group, the anesthesia method was nerve block + intravenous analgesia: ultrasound-guided left transverse abdominis plane block (0.25% ropivacaine 0.3 mL/kg)+bilateral rectus abdominis sheath block (0.25% ropivacaine 0.3 mL/kg per side)+intravenous injection of oxycodone 0.1 mg/kg, flurbiprofen 1 mg/kg, and dexamethasone 0.2 mg/kg. The primary outcome measure was the quality of requirements-15 (QoR-15) score at postoperative 24 h, while the secondary outcome measures were the QoR-15 score at postoperative 48 h, the numerical rating scale (NRS) and Bruggemann comfort scale (BCS) scores at different time points after the surgery, the first time of rescue analgesia, the first time of off-bed activity and intestinal exhaust, as well as the incidences of adverse reactions within postoperative 48 h.  Results  A total of 46 patients with end-stage head and neck cancer who underwent open gastrostomy and met the inclusion and exclusion criteria were ultimately enrolled, with 23 patients in multimodal analgesia group and 23 patients in local anesthesia group. There was no statistically significant difference in preoperative QoR-15 scores between the two groups (P > 0.05). Multimodal analgesia group had higher QoR-15 scores at 24 h postoperatively[(81.77±8.91) vs. (71.46±7.61), P < 0.05] and 48 h postoperatively[(86.26±7.92) vs. (80.13±6.98), P < 0.05], and the difference in QoR-15 scores at 24 h postoperatively was clinically significant. Compared with local anesthesia group, at 6 h and 24 h after surgery, the multimodal analgesia group showed a decrease in NRS scores at rest and during exercise, while the comfort BCS score increased (all P < 0.05). Multimodal analgesia group also had a delayed time for the first rescue analgesia, a reduced incidence of rescue analgesia within 48 h after surgery, an earlier time for first postoperative off-bed activity and intestinal exhaust (all P < 0.05). The incidence of adverse reactions in multimodal analgesia group and local anesthesia group was 8.70% and 13.04%, respectively, but the difference was not statistically significant (P > 0.05).  Conclusion  Intraoperative multimodal analgesia can effectively alleviate postoperative pain, increase the comfortable degree, shorten the first time of postoperative off-bed activity and intestinal exhaust, and accordingly improve the quality of early postoperative recovery in patients undergoing open gastrostomy.

Objective To observe the value of electron density map(EDM)from spectral CT combined with CT features in differentiating acute and chronic osteoporotic vertebral fractures(OVF).Methods Thoracic and/or lumbar spectral CT data of 48 patients with acute complicated chronic OVF were retrospectively analyzed.Totally 110 fractured vertebrae were enrolled,including 53 vertebrae with acute fractures(acute group)and 57 with chronic fractures(chronic group).The quantitative parameters of spectral CT,including CT values of conventional 120 kVp polyenergetic image(PI,i.e.routine CT images)and 40,70,100 keV virtual monoenergetic images(VMI),effective atomic number(Z-eff)and electron density(ED),as well as routine CT finding were compared between groups,and those being significantly different were included in multivariate logistic regression to screen the independent risk factors for acute OVF and construct a combined model.Receiver operating characteristic(ROC)curves were drawn to evaluate the efficacy of each single independent risk factor and the combination for differentiating acute and chronic OVF.Results Significant differences of all spectral CT quantitative parameters,also of routine CT findings including interruption of vertebral endplate,cortical folds,increased vertebral density,gas within vertebral body and vertebral compression degree were found between groups(all P＜0.05).Logistic regression analysis showed that CTPI(OR=0.855,P=0.005),ED(OR=16.432,P=0.005),cortical folds(OR=0.038,P=0.034)and increased vertebral density(OR=0.025,P=0.013)were all independent risk factors for acute OVF.The area under the curve(AUC)of the above single parameters for identifying acute and chronic OVF was 0.870,0.889,0.879 and 0.866,respectively,all lower than that of the combined model(0.977)(Z=3.47,3.73,2.95,2.71,all P＜0.05).Conclusion Spectral CT EDM combined with CT findings could effectively differentiate acute and chronic OVF.
