OBJECTIVE To investigate the effects of dexmedetomidine （DEX）-assisted general anesthesia on hemodynamics and cognitive function in elderly patients undergoing painless enteroscopy. METHODS From July 2020 to February 2022， 180 elderly patients undergoing painless enteroscopy in the outpatient operating room of the Second People’s Hospital of Jiaozuo were selected and divided into a control group （n＝90） and an observation group （n＝90） according to the random number table method. The control group was given routine general anesthesia （induced with sufentanil and propofol anesthesia， maintained with propofol anesthesia）， while the observation group was given DEX-assisted general anesthesia after preoperative preparation. The hemodynamic indexes [mean arterial pressure （MAP）， heart rate （HR）]， dosage of general anesthesia， awakening time， cognitive function [minimized mental status examination （MMSE）]， and the incidence of adverse drug reactions were compared between the two groups. RESULTS There was no significant difference in various indicators before anesthesia （T0） between 2 groups （P＞ 0.05）. Compared with T0， MAP and HR of the two groups were reduced significantly 10 minutes after anesthesia （T1）， at the time of enteroscope reaching the ileum and cecum （T2）， enteroscope withdrawal after the examination （T3）， and 10 minutes after surgery （T4）； but MAP and HR of the observation group at T1， T2， T3， and T4 were all higher than those of the control group （P＜0.05）. Compared with the control group， the dosage of general anesthesia and the recovery time in the observation group were significantly reduced or shortened， the MMSE scores at 1， 2 and 3 days after the operation were significantly increased， while the incidence of cognitive dysfunction and adverse reactions were significantly reduced （P＜0.05）. CONCLUSIONS DEX can effectively improve the hemodynamics and cognitive function of elderly patients undergoing painless enteroscopy， which is beneficial to reduce the dosage of general anesthesia， shorten recovery time， and has better safety.

BACKGROUND:Postoperative delirium is one of the serious complications after total knee arthroplasty,usually occurring 1-5 days after surgery,with confusion and cognitive impairment as the main manifestations,which is not conducive to the recovery of joint function in elderly patients.At present,the risk factors affecting delirium after total knee arthroplasty in the elderly are not clear,and there is a lack of clinical prediction studies to directly present them for promotion and application. OBJECTIVE:To explore the risk factors of delirium after total knee arthroplasty in elderly patients and establish a prediction model of nomogram. METHODS:Medical record data of 116 elderly patients receiving total knee arthroplasty treated in Ganzhou Hospital of Traditional Chinese Medicine,Jiangxi University of Chinese Medicine from January 2019 to December 2021 were retrospectively analyzed,of which 29 elderly patients with delirium after total knee arthroplasty were selected as the observation group,and the remaining 87 elderly patients without delirium after total knee arthroplasty were selected as the control group.Preoperative general clinical data,laboratory examination results,and surgical data were compared between the two groups.Multivariate Logistic regression analysis was used to analyze risk factors for delirium after total knee arthroplasty in elderly patients.The receiver operating characteristic curve was used to analyze the independent risk factors and obtain the best cut-off value.The nomogram model was constructed by R software. RESULTS AND CONCLUSION:(1)There were significant differences in age,cerebrovascular accident history,preoperative hospital stay,preoperative albumin,hemoglobin,American Society of Anesthesiologists classification,operation time,anesthesia time,and intraoperative blood transfusion volume between the two groups(P<0.05).(2)Multivariate Logistic regression analysis showed that old age,long hospital stay before surgery,high American Society of Anesthesiologists classification grade,and long operation time were risk factors for postoperative delirium in elderly knee arthroplasty patients,while high albumin and high hemoglobin were protective factors for postoperative delirium in elderly knee arthroplasty patients.(3)The areas under the curve of age,preoperative hospital stay,albumin,hemoglobin,American Society of Anesthesiologists classification grade,and operation time were 0.784,0.706,0.853,0.762,0.617,and 0.542,respectively.The optimal cut-off values were 75 years,7 days,40 g/L,125 g/L,3 and 200 minutes,respectively.(4)After internal data for verification,the consistency index was 0.974.The actual curve of the model was in good agreement with the ideal curve.(5)These results indicate that this nomogram model based on old age,long hospital stay,high American Society of Anesthesiologists classification grade,low albumin,low hemoglobin,and long operation time has far-reaching clinical significance for early identification,early warning and diagnosis of delirium risk in elderly patients after total knee arthroplasty.

ObjectiveTo explore the risk factors and survival analysis of chemotherapy compliance in ≥65 years old patients with non-small cell lung cancer. MethodsFrom December 2018 to August 2020， 110 patients with non-small cell lung cancer ≥65 years old in our hospital were selected for study. According to their chemotherapy compliance， the patients were divided into untreated （25 cases）， partial chemotherapy （30 cases） and full chemotherapy （55 cases）. Multivariate Cox regression was used to analyze the independent risk factors affecting the compliance of chemotherapy among the three groups， and constructed a column chart prediction model and evaluated the diagnostic effectiveness of the model using receiver operating characteristic （ROC） curves， calibration curves， and clinical decision curves. The patients were followed up until August 2023. Kaplan-Meyer survival curve and Log-rank test were used to compare the differences in survival time between the groups. ResultsThere were significant differences among the three groups in gender， long-term smoking history， education level， Charlson complication index， toxic and side effects of chemotherapy drugs and dosage， pathological type， operation mode， place of residence， payment mode， chemotherapy stage， white blood cell count and neutrophils （P<0.05）. Multivariate Cox analysis showed that patients' education level， pathological TNM stage， toxic and side effects of chemotherapy drugs and dosage， operation mode， residence， payment mode and chemotherapy stage were independent risk factors affecting chemotherapy compliance of patients with non-small cell lung cancer （all P<0.05）. There were significant differences in the survival rates between the non-chemotherapy group and the full chemotherapy group， and between the partial chemotherapy group and the full chemotherapy group （P<0.05）， but there was no significant difference between the non-chemotherapy group and the partial chemotherapy group （P>0.05）. And based on this， a prediction model was constructed， and the ROC curve was drawn to show that the AUC of the model was 0.758 （95%CI： 0.743‒0.855）， the sensitivity was 0.788， and the specificity was 0.853， indicating that the model had high discrimination， the calibration curve indicated that the prediction model had good accuracy， the clinical decision curve indicated that the predictive model had strong clinical practicality. ConclusionNSCLC tends to occur in the elderly. We should focus on the patients with low educational level， late pathological TNM stage， severe toxicity and side effects， high dose of chemotherapy drugs， having undergone open chest surgery， living in rural areas， without medical insurance， and in the period of chemotherapy consolidation and refractory relapse， so as to improve their compliance with chemotherapy.

BACKGROUND:At present,wrist protection products designed in and outside China have not solved the contradiction between protecting the wrist joint from injury and maintaining the flexible movement of the wrist joint. OBJECTIVE:To investigate the biomechanical mechanism of dorsiflexion injury of the wrist joint in elderly people after falls,and to provide a biomechanical basis for the prevention and treatment of wrist injury in elderly people after falls. METHODS:A 65-year-old man was selected to obtain the original data by uninterrupted CT scan of the middle and lower 2/3 of his left forearm up to the end of the finger.A finite element model of wrist dorsiflexion was established using ANSYS 12.0 finite element software.The palm surface of the model was constrained,and the model at a velocity load of 2 m/s in the direction of vertical downward was given to simulate the injury state of the palm when the elderly fall.The stress distribution of the soft tissues and bones of the wrist joint and the change of the stress with time were observed after the load was applied. RESULTS AND CONCLUSION:(1)A realistic and effective finite element model of the dorsal extension position of the wrist joint of the elderly was established.The soft tissue stresses were mainly concentrated in the small fissure of the palm and the dorsal side of the wrist after loading.The skeletal stresses were mainly concentrated in the lower end of the ulnar radius dorsally.The stresses in the lower end of the radius were the greatest.The palmar stresses were mainly concentrated in the middle and lower 1/3 of the radius and the hook bone.The stress distribution of the ulnar radius was asymmetric,and the stresses in the radius were more concentrated.(2)The results of the study are consistent with the clinical situation of a fallen wrist injury in elderly people,and can be used to explain the mechanism of wrist dorsiflexion injury,which can provide the biomechanical basis for the design of wrist protection devices that can be used to prevent wrist injury induced by falling and the treatment of wrist injury in elderly people.

OBJECTIVE To analyze influential factors for dabigatran exposure in elderly patients with non-valvular atrial fibrillation. METHODS The clinical information of 75 elderly patients diagnosed with non-valvular atrial fibrillation was collected from our hospital in Jan. 2019-Jun. 2020. One or two steady-state blood drug concentration samples were collected from each patient. NONMEM 7.2.0 software was used to establish a population pharmacokinetics model of dabigatran； the effects of different covariates on the apparent clearance of dabigatran were investigated， and the final model was verified by goodness of fit and Bootstrap method； NONMEM 7.2.0 software was used to analyze the drug exposure of ordinary elderly patients and elderly patients after taking dabigatran ester in different disease states. RESULTS Totally 122 blood concentration samples of dabigatran were collected. Advanced age， creatinine clearance and history of chronic heart failure were screened out as three significant covariates that influenced the clearance of dabigatran in elderly patients. The exposure of population with advanced age increased by about 50% compared with the general elderly， the exposure of population with history of chronic heart failure increased by nearly 30% compared with population without， and the exposure of population with moderate and severe renal injury increased by about 30% and 80% compared with mild. CONCLUSIONS Advanced age， renal injury and history of chronic heart failure are influential factors for elevated systemic exposure of dabigatran.

【Objective】 To explore the effects of acute normovolemic hemodilution (ANH) combined with intraoperative recycled autotransfusion on blood transfusion volume and coagulation function in elderly patients undergoing cardiac surgery. 【Methods】 A total of 94 elderly patients undergoing cardiac surgery in the hospital were enrolled and randomly divided into observation group (n=47) and control group (n=47) between March 2020 and March 2022. The observation group was given ANH combined with intraoperative recycled autotransfusion, while control group was given routine allogeneic transfusion. The blood transfusion volume, oxygenation status, immune function, inflammatory indexes and adverse reactions in the two groups were compared. 【Results】 The banked blood transfusion volume was less in observation group than control group [(1.73±0.43) U vs (5.71±1.71) U, P<0.05]. At 6 h after surgery, blood oxygen saturation (SvO2) level was higher [(74.59±7.20) % vs (67.22±6.19) %], while oxygen uptake rate (ERO2) level was lower[(0.29±0.06) % vs (0.34±0.05) %] in observation group than control group (P<0.05). At day 1 after surgery, levels of CD3+, CD4+, CD4+ /CD8+ and natural killer cells (NK) were higher [(65.11±5.14) %, (46.93±5.17) %, (1.86±0.30), (8.35±1.23) % vs (57.45±7.24) %, (43.58±4.85) %, (1.47±0.36)%, (7.34±1.38) %], while CD8+ was lower [(25.17±4.01) % vs (30.39±5.06) %] in observation group than control group (P<0.05). At day 1 after surgery, levels of serum interleukin 6/8 (IL-6/8) and tumor necrosis factor-α (TNF-α) were lower in observation group than control group [(104.51±12.55) ng/L vs (125.81±14.96) ng/L, (351.42±52.86) ng/L vs (394.27±55.78) ng/L, (254.93±49.94) ng/L vs (323.60±52.63) ng/L, P<0.05]. The incidence of adverse reactions was lower in observation group than control group (4.26% vs 17.02%), P<0.05. 【Conclusion】 Recycled autotransfusion can reduce allogeneic transfusion volume in elderly patients undergoing cardiac surgery. There is no difference in the effects on blood routine or coagulation function between recycled autotransfusion and allogeneic transfusion. Compared with allogeneic transfusion, recycled autotransfusion can significantly improve oxygenation status, relieve immunosuppression and inflammation response, and reduce the risk of adverse reactions.

Objective:To introduce a surgical method and clinical effect of using Masquelet technique combined with skin graft to cover chronic refractory wounds in elderly patients.Methods:From September 2020 to September 2022, 20 elderly patients with wounds of bone or tendon exposure in lower limbs were treated in the Department of Wound Repair, the Second Affiliated Hospital of Wenzhou Medical University. Due to the age and poor general condition of the patients, flap transfer for wound coverage were not allowed. Masquelet technique was therefore applied in the treatment of chronic wounds of such patients. Sizes of wounds were found at 4.5 cm×3.0 cm to 15.0 cm×6.0 cm and all accompanied with tendon and bone exposure, after thorough debridement. Wounds were then sealed with antibiotic bone cement several times. After having induced formation of membrane in wounds, free mesh skin graft was used to cover the refractory wounds. The patients were entered in follow up regularly after surgery at outpatient service, and telephone or video reviews. The wound healing of patients and whether there were related complications in the skin donor area were observed. The number of operation times in the first stage was 1-4 with an average of 1.3 times ± 0.7 times. Lower Extremity Function Scale (LEFS) was used to evaluate the recovery of lower limb function.Results:All 20 wounds healed well. The follow-up time was 3-12 months, with an average of 7.6 months. The appearance and texture of the skin in the wounds area were satisfactory. The mean LEFS was 69.83 point ± 10.82 point.Conclusion:Using Masquelet technique combined with free skin grafting to treat refractory wounds in the elderly patients can achieve satisfactory clinical outcomes. It is a simple and reliable supplement to the wound repair, and can reduce the surgical risk.

Objective:To compare the perioperative outcomes between robotic pancreaticoduodenectomy(RPD)and laparoscopic pancreaticoduode-nectomy(LPD)in patients aged ≥65 years. Methods:The clinical data of 130 patients aged ≥65 years who received minimally invasive pancreaticoduodenectomy(MIPD)at Department of Gastrointestinal and Pancreatic Surgery,Zhejiang Provincial People's Hospital from January 2019 to December 2022 were retrospectively analyzed.The patients were divided into the RPD group(n=66)and the LPD group(n=64)according to the operation method,and the perioperative clinical data were compared between the 2 groups. Results:Compared with the LPD group,the average age of patients in the RPD group was higher than that of the LPD group[(71.95±4.73)years vs(70.39±3.9)years,P＜0.05];the RPD group had more patients with diabetes(39.4％vs 18.8％,P＜0.05)and cardiopulmonary diseases(37.9％vs 17.2％,P＜0.05);the RPD group had shorter operation time[(272.91± 68.38)min vs(362.81±78.24)min,P＜0.05]and less intraoperative blood loss[median(range):1 00 mL(50-200 mL)vs 1 50 mL(1 00-200 mL),P＜0.05)];the RPD group had higher incidence of chylous fistula(1 2.1％vs 1.6％,P＜0.05)but lower incidence of surgical morbidity(37.9％vs 46.9％),serious complications(19.7％vs 34.4％),postoperative pancreatic fistula(12.1％vs 17.2％),biliary fistula(3.0％vs 3.1％),abdominal infection(10.6％vs 14.1％),postoperative bleeding(4.5％vs 4.5％),and postoperative cardiopulmonary complications(1 2.1％vs 20.3％)with no statistically significant difference(P＞0.05);the RPD group waited shorter time before restarting diet[(3.97±1.59)d vs(5.34±2.56)d,P＜0.05]. Conclusion:MIPD is safe and feasible in patients aged ≥65 years.The incidence of perioperative complications is similar between the 2 groups.Compared with LPD,RPD has shorter operation time,less intraoperative blood loss,and shorter duration before restarting diet after operation,which has certain clinical advantages.

Objective To explore the risk factors of clopidogrel resistance (CR) in the elderly patients with atherosclerotic cardiovascular disease and to provide evidence for the antiplatelet therapy. Methods A total of 223 elderly patients (≥80 years old) with atherosclerotic cardiovascular disease treated in the Department of Geriatrics in the Peking University People's Hospital from January 18,2013 to November 30,2019 and meeting the inclusion criteria were enrolled in this study.The clinical data and laboratory test results were collected,including clinical disease,drug use,physical examination,complete blood cell analysis,biochemical indicators,and thromboelastogram (TEG).The rate of platelet inhibition induced by adenosine diphosphate was calculated according to the TEG.We assigned the patients into a CR group (n=84) and a control group (n=139) to analyze the incidence and influence factors of CR in the elderly patients with atherosclerotic cardiovascular disease. Results The incidence of CR was 37.7% in the elderly patients with atherosclerotic cardiovascular disease.The CR group had lower hemoglobin (t=3.533,P=0.001) and higher hypertension prevalence rate (χ2=6.581,P=0.006),proportion of multiple drugs (χ2=3.332,P=0.048),body mass index (BMI) (t=-2.181,P=0.030),total cholesterol (t=-2.264,P=0.025),triglycerides (Z=-2.937,P=0.003),low-density lipoprotein cholesterol (LDL-C) (t=-2.347,P=0.020),and proportion of women (χ2=5.562,P=0.014) than the control group.The results of multivariate Logistic regression showed that hemoglobin (OR=0.962,P<0.001),BMI (OR=1.154,P=0.003),and LDL-C (OR=1.688,P=0.018) were the factors influencing CR in the elderly patients with atherosclerotic cardiovascular disease. Conclusion Hemoglobin,BMI,and LDL-C may be independent factors associated with the occurrence of CR in the elderly patients with atherosclerotic cardiovascular disease.

OBJECTIVES@#With the rapid development of aging population, the number of elderly patients undergoing posterior lumbar spine surgery continues to increase. Lumbar spine surgery could cause moderate to severe postoperative pain, and the conventional opioid-based analgesia techniques have many side effects, which are barriers to the recovery after surgery of the elderly. Previous studies have demonstrated that erector spinae plane block (ESPB) could bring about favorable analgesia in spinal surgery. As far as the elderly are concerned, the analgesic and recovery effects of ESPB on posterior lumbar spine surgery are not completely clear. This study aims to observe the effects of bilateral ESPB on elderly patients undergoing posterior lumbar spine surgery, and to improve the anesthesia techniques.@*METHODS@#A total of 70 elderly patients of both sex, who were selected from May 2020 to November 2021, scheduled for elective posterior lumbar spine surgery, and in the age of 60-79 years, with American Society of Anesthesiologists class Ⅱ-Ⅲ, were divided into a ESPB group and a control (C) group using a random number table method, with 35 patients each. Before general anesthesia induction, 20 mL 0.4% ropivacaine was injected to the transverse process of L3 or L4 bilaterally in the ESPB group and only saline in the C group. The score of Numerical Rating Scale (NRS) indicating pain at rest and on movement within 48 h after operation, time of first patient control analgesia (PCA), cumulative consumptions of sufentanil within 48 hours, Leeds Sleep Evaluation Questionnaire (LSEQ) scores on the morning of day 1 and day 2 after operation, Quality of Recovery-15 (QoR-15) scores at 24 and 48 h after operation, full diet intake times, perioperative adverse reactions such as intraoperative hypotension, postoperative dizziness, nausea, vomiting, and constipation were compared between the 2 groups.@*RESULTS@#A total of 70 patients were enrolled and 62 subjects completed the study, including 32 in the ESPB group and 30 in the C group. Compared with the C group, the postoperative NRS scores at rest at 2, 4, 6, and 12 h and on movementat at 2, 4, and 6 h were lower, time of first PCA was later, sufentanil consumptions were significantly decreased during 0-12 h and 12-24 h after operation, LSEQ scores on the morning of day 1 and QoR-15 scores at 24 and 48 h after operation were higher, full diet intakes achieved earlier in the ESPB group (all P<0.05). There were no significant differences in the incidences of intraoperative hypotension, postoperative dizziness, nausea, vomiting, and constipation between the 2 groups (all P>0.05).@*CONCLUSIONS@#Providing favorable analgesic effects with reduced opioids consumption, bilateral ESPB for posterior lumbar spine surgery in the elderly patients could also improve postoperative sleep quality, promote gastrointestinal functional restoration, and enhance recovery with few adverse reactions.

OBJECTIVE@#To review the research progress of rapid surgery for hip fracture in elderly patients.@*METHODS@#The published studies, expert consensus, and guidelines at home and abroad were systematically summarized from the aspects of the characteristics of aging population, the benefits of rapid surgery, the disadvantages of delayed surgery, and the recommendations of current guidelines, so as to further guide clinical practice.@*RESULTS@#Hip fracture is a common fracture type in the elderly population. As elderly patients generally have poor physique and often have a variety of underlying diseases, such as hypostatic pneumonia, bedsore, lower limb vein thrombosis, and other complications in conservative treatment, its disability rate and mortality are high, so surgical treatment is the first choice. At present, most relevant studies and expert consensus and guidelines at home and abroad support rapid surgery, that is, preoperative examination should be started immediately after admission, and adverse factors such as taking anticoagulant drugs, serious cardiovascular diseases, and severe anemia should be clearly and actively corrected, and surgery should be completed within 48 hours after admission as far as possible. Rapid surgery can not only significantly reduce the mortality of patients, but also reduce the length of hospital stay and the incidence of perioperative cognitive impairment, which is conducive to the recovery of patients with pain during hospitalization and postoperative function, and improve the prognosis of patients.@*CONCLUSION@#In order to avoid many problems caused by delayed surgery, the elderly patients with hip fracture should be operated as soon as possible under the condition of actively correcting the adverse factors. Comprehensive evaluation and preparation, the development of an individualized surgical plan, and the formation of a multidisciplinary medical team can reduce surgical risks and improve effectiveness.

Objective Dexmedetomidine is a highly selective alpha-2 adrenergic receptor agonist with sedative and analgesic properties but without respiratory depression effect and has been widely used in perioperative anesthesia. Here we performed a systematic review and meta-analysis to evaluate the effect of dexmedetomidine on maintaining perioperative hemodynamic stability in elderly patients.Methods PubMed, Web of Science, the Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wanfang Data were searched for randomized-controlled trials (RCTs) on the application of dexmedetomidine in maintaining perioperative hemodynamic stability in elderly patients from their inception to September, 2021. The standardized mean differences (SMD) with 95% confidence interval (CI) were employed to analyze the data. The random-effect model was used for the potential clinical inconsistency.Results A total of 12 RCTs with 833 elderly patients (dexmedetomidine group, 546 patients; control group, 287 patients) were included. There was no significant increase in perioperative heart rate (HR), mean arterial pressure (MAP), and diastolic blood pressure (DBP) in the dexmedetomidine group before and during the operation. In addition, the variations of hemodynamic indexes including HR, MAP, SBP (systolic blood pressure), and DBP were significantly lower in the dexmedetomidine group compared with the control group (HR: SMD = -0.87, 95% CI: -1.13 to -0.62; MAP: SMD = -1.12, 95% CI: -1.60 to -0.63; SBP: SMD = -1.27, 95% CI: -2.26 to -0.27; DBP: SMD = -0.96, 95% CI: -1.33 to -0.59). Subgroup analysis found that with the prolongation of 1.0 μg/kg dexmedetomidine infusion, the patient's heart rate declined in a time-dependent way.Conclusion Dexmedetomidine provides more stable hemodynamics during perioperative period in elderly patients. However, further well-conducted trials are required to assess the effective and safer doses of dexmedetomidine in elderly patients.

OBJECTIVE@#To evaluate the clinical outcomes of reverse total shoulder arthroplasty as a revision procedure for the failed fixation of proximal humeral fractures in the elderly patients.@*METHODS@#A retrospective analysis was performed on 8 patients with failed internal fixation of proximal humeral fractures from May 2014 to March 2020, including 3 males and 5 females, aged from 65 to 75 years old. All 8 patients underwent reverse total shoulder arthroplasty, and the mean time between initial fixation and reverse total shoulder arthroplasty ranged from 8 to 16 months. Range of motion(ROM), University of California at Los Angeles(UCLA) shoulder score, visual analogue scale (VAS), self-rating anxiety scale(SAS), and Constant-Murley score of shoulder function were assessed pre-operatively and at the last follow-up. Complications relating to the surgery were recorded.@*RESULTS@#All 8 patients successfully followed up. The mean follow-up after reverse total shoulder arhroplasty ranged from 16 to 28 months. The range of motion (forward flexion, external rotation, abduction and internal rotation) of the affected shoulder was significantly improved after surgery, and the post-operative VAS, SAS and UCLA scores were also significantly improved. For the Constant-Murley score of shoulder joint function, the total scores and the subscores of pain, daily activities, range of motion and strength test at the last follow-up were all significantly improved. Scapular glenoid notch was observed in patient, which was evaluated as grade 1 on imaging. All the other patients did not develop specific or non-specific complications.@*CONCLUSION@#Reverse total shoulder arhroplasty is an appropriate treatment as a revision surgery for failed fixation of proximal humeral fractures. It has shown satisfactory clinical outcomes, accelerating the rehabilitation of shoulder function and improving the quality of life.

OBJECTIVE To explore the pharmaceutical care model for elderly patients with drug-related problems （DRPs） based on the comprehensive medication management review （CMMR）， and to observe the effect of pharmaceutical care under the model. METHODS The pharmaceutical care new model for elderly patients was established by concerning CMMR guidelines in Australia. In other words， clinical pharmacists receive medical care through referral by health practitioners and active consultation by patients or their caregivers. Visits were made by a combination of face-to-face and telephone interviews. Follow-up was carried out in the form of outpatient follow-up， telephone follow-up， appointment， and home guidance to know about the treatment of DRPs by healthcare practitioners or patients.Under this model， the occurrence status and classification of DRPs in elderly patients were studied through cross-sectional investigation. The effect of pharmaceutical care was evaluated from the aspects of hospitalization rate， adverse drug reaction （ADR） incidence，medication compliance， the number of medications， blood lipid level， etc.， through self-before-after comparison. RESULTS In this study， a patient-centered， evaluation-intervention-reevaluation closed-loop pharmaceutical care model was formed. Among 317 study subjects， the average number of DRPs was 1.03 （0-7） cases. Compared before and after the intervention， the number of drug types increased from 2.00（0.00，3.00） to 2.00（1.00，3.00）， but the level of low-density lipoprotein cholesterin in patients decreased from 3.48 （2.58， 4.29） mmol/L to 3.11 （2.29，3.81） mmol/L （P＜0.05）. There was no statistical significance in hospitalization rate， ADR incidence within or medication compliance. CONCLUSIONS CMMR-based pharmaceutical care model can effectively identify and manage the patients’ DRPs and reduce the level of blood lipid.

Objective:To analyze the clinical characteristics of PHPT in elderly patients, as well as the safety and effectiveness of surgical treatment.Methods:179 patients with PHPT treated from Jan. 2000 to Dec. 2020 were analyzed retrospectively. They were divided into elderly group ( n=51) and non-elderly group ( n=128) according to whether they were over 60 years old at the time of operation. The clinical data of symptoms, complications, preoperative and postoperative blood calcium, phosphorus, ALP, PTH, surgical cure rate and complication rate of the two groups were analyzed retrospectively. T-test was used for measurement data comparison. χ2 test was used for enumeration data comparison and single factor analysis. Logistic regression analysis (forward method) was used for multivariate analysis. Results:The proportion of non-specific symptoms in the elderly group, including fatigue, dizziness, loss of appetite, memory decline, was higher than that in the non-elderly group (21.6% vs 8.6%, P=0.019) . Elderly patients had lower blood ALP level[ (163.4±229.8) U/L vs (325.9±449.2) U/L, P=0.016], higher proportion of preoperative hypertension (47.1% vs 21.1%, P=0.001) , diabetes (31.4% vs 10.9%, P=0.001) , coronary heart disease (13.7% vs 3.1%, P=0.013) and tumor (13.7% vs 3.9%, P=0.025) . High proportion of non-specific symptoms was related to higher blood calcium [ OR=4.936 (95% CI 1.126-21.637) , P=0.034] and lower blood phosphorus[ OR=0.011 (95% CI 0.000-0.650) , P=0.030]. Between the two groups there was no significant difference in cure rate (94.1% vs 96.1%, P=0.564) or complication rate (27.5% vs 44.5%, P=0.127) . Conclusions:The surgical treatment of elderly patients with PHPT also has high effectiveness and safety. More attention should be paid to surgical diagnosis and treatment of elderly patients.

Objective:To establish a prediction model of acute upper gastrointestinal rebleeding (AUGIRB) for elderly patients by combining and applying multiple indicators.Methods:A retrospective observational study was conducted. The clinical data of 161 elderly patients (age ≥ 65 years old) who suffered from acute upper gastrointestinal bleeding (AUGIB) and who were hospitalized in Shanghai General Hospital from July 2018 to December 2020 were recorded. The patients were divided into the rebleeding group (31 cases) and the non-rebleeding group (130 cases) according to whether gastrointestinal rebleeding occurred. Univariate analysis was adopted to screen AUGIRB-related risk factors and Logistic regression analysis was used to screen independent predictors of AUGIRB so that a predictive model was constructed. Based on the area under the curve (AUC) of the receiver operator characteristic curve (ROC curve), the predictive ability of the prediction model for AUGIRB was evaluated, the optimal cut-off value was determined, and the odds ratio ( OR) and its 95% confidence interval (95% CI) were calculated. Bootstrap resampling technology was used to validate the predictive ability of the model. Results:Univariate Logistic analysis showed that oral anticoagulant drugs, oral antiplatelet drugs, albumin (ALB), platelet count (PLT), Glasgow-Blatchford bleeding score (GBS), D-dimer, fibrinogen (FIB), and international normalized ratio (INR) all had a significant effect on the occurrence of AUGIRB among elderly patients. Multivariate Logistic regression analysis showed that the oral antiplatelet drugs ( OR = 11.150, 95% CI was 1.888-65.852, P < 0.05) and GBS score ( OR = 2.503, 95% CI was 1.523-4.114, P < 0.05) were the independent risk factors of AUGIRB among elderly patients, while the ALB ( OR = 0.764, 95% CI was 0.626-0.932, P < 0.05) and FIB ( OR = 0.065, 95% CI was 0.011-0.370, P < 0.05) were the protective factors of AUGIRB among elderly patients. The AUC of the above four indexes joint prediction model was 0.979. The verification results of the model showed that the consistency index (C-index) of the model was 0.986. Conclusion:The prediction model fitted in this research has a high prediction accuracy and it also has a certain reference value for the judgment of elderly patients who suffer from AUGIRB.
