Objective To explore the value of combined detection of lipoprotein-associated phospholipase A2(Lp-PLA2),neuron specific enolase(NSE)and S-100 calcium binding protein β(S-100β)in the diagnosis and prognosis evaluation of acute cerebral infarction(ACI)in patients with carbon monoxide poisoning(CMP).Methods A total of 102 patients with CMP complicated with ACI admitted to the hospital from Jan-uary 2020 to November 2021 were selected as the study group,meanwhile,102 patients with simple CMP were enrolled as the control group.Patients in the study group were followed up for 6 months after discharge,ac-cording to the follow-up results,they were grouped into good prognosis group(60 cases)and poor prognosis group(42 cases).The serum levels of Lp-PLA2,NSE and S-100β were detected by enzyme-linked immunosor-bent assay(ELISA).The receiver operating characteristic(ROC)curve was applied to analyze the value of the combination of serum Lp-PLA2,NSE and S-100β in the early diagnosis and prognosis evaluation of patients with CMP and ACI.Results Compared with the control group,the levels of Lp-PLA2,NSE and S-100β in the study group were obviously higher(P<0.05).The ROC curve analysis results showed that the area under the curve(AUC)of the combined detection of serum Lp-PLA2、NSE、S-100β for the diagnosis of CMP complicat-ed with ACI was greater than the AUC of single detection of each indicator(P<0.001).Compared with the good prognosis group,the levels of Lp-PLA2,NSE and S-100β in the poor prognosis group were obviously higher(P<0.05).The results of ROC curve analysis showed that the AUC of the combined detection of ser-um Lp-PLA2、NSE、S-100β for the prognosis of patients with CMP complicated with ACI was greater than the AUC of single detection of each indicator(P<0.05).Conclusion The expression of Lp-PLA2,NSE and S-100β in serum of patients with CMP complicated with ACI is high,and the combined detection of the three has certain value in the diagnosis and prognosis evaluation for patients with CMP complicated with ACI.

Objective:To investigate the prevalence and mortality of dementia and assess the impact of geriatric syndromes (GS) on the risk for dementia and death in elderly population in Beijing.Methods:A cross-sectional survey was conducted in the elderly population aged ≥65 years and selected by a multi-stage sampling in Beijing during 2013-2015. Cognitive function was screened using the Chinese Revised Version of the Mini-Mental State Examination (MMSE). Then, neurological examination and psychiatric assessment were performed for those with the MMSE score lower than the cut-off value. The information about GS prevalence was also collected. The study also collected death records for all individuals from baseline until December 31, 2019. Based on the age and gender distribution from Beijing data of the 2010 Six th National Population Census, the dementia prevalence in the study population was directly standardized. Logistic regression analysis was used to evaluate the association of different forms of dementia with GS, and Cox proportional hazards regression model was used to estimate the hazard ratio ( HR) and 95% CI of death. Results:During 2013-2015, a total of 2 935 individuals completed dementia assessments, of which 167 were diagnosed with dementia. The standardized prevalence of dementia was 5.9% (95% CI: 5.0%-17.4%). The individuals with Alzheimer's disease (AD) and vascular dementia (VaD) accounted for 58.7% and 28.1% of total individuals with dementia, respectively. Aging, lower education level, urinary incontinence, and fall were risk factors for AD, while disability of activity of daily life dependence, hypertension, and stroke were found to be risk factors for VaD. After a median follow-up of 5.44 person-years, 399 deaths were recorded. The 5-year mortality risk was 2.87 (95% CI: 1.92-4.17) times and 4.93 (95% CI: 3.23-7.53) times higher for the elderly individuals with AD and VaD, respectively, compared to non-demented individuals. After adjusting for demographic, GS, and cardiovascular risk factors, the mortality risk in the elderly individuals with AD showed no significant difference compared with non-demented individuals ( HR=1.32, 95% CI: 0.89-1.97), while the mortality risk in those with VaD was 2.46 (95% CI: 1.49-4.05) times higher than that in non-demented individuals. Conclusions:The prevalence of dementia in Beijing increased significantly in the context of population aging, especially the prevalence of AD. The presence of GS increased the risks for AD and VaD, as well as the risk for death. Close attention needs to be paid to GS management in dementia prevention in elderly population.

Background and purpose:Currently,for patients with mid-to-low locally advanced rectal cancer and potentially resectable T4bM0 colon cancer,guidelines recommend neoadjuvant therapy strategies to enhance the response rate and increase the likelihood of conversion surgery.Among these patients,ypⅢ stage colorectal cancer(CRC)is assessed using the Union for International Cancer Control(UICC)/American Joint Committee on Cancer(AJCC)TNM staging system for postoperative pathological features.However,neoadjuvant therapy can lead to lymph node regression in the surgical area,resulting in an insufficient number of detected lymph nodes(less than 12),preventing classification according to conventional TNM staging.Thus,TNM staging often fails to predict the prognosis of ypⅢ patients who have undergone neoadjuvant therapy.This study aimed to evaluate the prognostic value of the positive lymph node ratio(LNR)in ypⅢ stage CRC patients treated with neoadjuvant therapy.Methods:Retrospective data was collected from ypⅢ stage CRC patients who received neoadjuvant therapy and underwent radical surgery at Fudan University Shanghai Cancer Center between 2008 and 2018.Collect clinical pathological characteristics such as age,gender,primary tumor location,tumor differentiation grade,pathological staging,and whether the patient has relapsed or died during follow-up at the time of surgery.Inclusion criteria:CRC patients who have received neoadjuvant therapy and surgery and have been confirmed to be stage Ⅲ by postoperative pathological examination.Exclusion criteria:① Preoperative imaging examination or intraoperative exploration reveals distant organ metastasis;② History of malignant tumors in the past;③ Multiple primary CRC.This study was approved by the medical ethics committee of Fudan University Shanghai Cancer Center(ethics number:050432-4-2108*).The R software survminer package(surv_cutpoint algorithm)was used to calculate the optimal cutoff value for LNR relative to disease-free survival(DFS),and patients were divided into low and high LNR groups accordingly.Clinical pathological characteristics and DFS were compared between the two groups.COX proportional hazards regression models were employed to identify adverse pathological features,and survival plots along with prediction models for DFS were generated using the survival and rms packages.Results:A total of 489 patients were included,comprising 289 males and 200 females,with a median age of 56 years(23-80 years)and a median follow-up time of 1 062 d.During the follow-up period,164 patients(33.5%)died.In the entire cohort,204(41.7%)patients had fewer than 12 lymph nodes detected.The optimal cutoff value for LNR was 0.29,classifying 317 patients into the low LNR group(LNR≤0.29)and 172 patients into the high LNR group(LNR＞0.29).The high LNR group exhibited shorter DFS compared to the low LNR group[hazard ratio(HR)=2.103,95%CI:1.582-2.796,P＜0.000 1].Multivariate COX regression indicated that LNR was an independent prognostic factor for DFS(HR=1.825,95%CI:1.391-2.394,P＜0.001).The inclusion of LNR in a multicategory DFS nomogram prediction model effectively assessed DFS in stage Ⅲ CRC patients who had undergone neoadjuvant therapy.Conclusion:LNR is an independent prognostic factor for ypⅢ stage CRC patients,showing good predictive power for DFS when combined with other adverse pathological features.Therefore,incorporating LNR as a supplement to TNM staging can improve the accuracy of CRC prognosis assessment.

OBJECTIVE To explore the potential targets and mechanisms of the modified Baihe dihuang decoction （MBD/ BDD） applied in post-stroke depression （PSD）. METHODS Network pharmacology was used to mine the potential targets and key pathways of MBD/BDD in the treatment of PSD. PSD model rats were induced by focal cerebral ischemia surgery combined with chronic unforeseen mild stress， and then were randomly divided into PSD model group， MBD/BDD group （12.6 g/kg， by raw drug）， and fluoxetine hydrochloride （FLX） group （positive control， 2.3 mg/kg）； a blank control group was also set up， with 8 rats in each group. Each administration group was given a corresponding medication solution by gavage once a day for 21 consecutive days. The intervention effect of MBD/BDD on depression-like symptoms in model rats was evaluated by open field and forced swimming tests. The brain tissues of rats in each group were dissected and total RNA was extracted for transcriptome sequencing and bioinformatics analysis. The mRNA and protein expressions of genes with significant changes and common neurotrophic factors were verified based on the above results. RESULTS A total of 131 MBD/BDD antidepressant-related target genes were obtained （such as IL1B and AKT1， etc.）， which were closely related to neural active ligand-receptor interactions and cyclic adenosine monophosphate signaling pathway. MBD/BDD could significantly prolong or increase the total time spent and distance traveled in the central grid of qiangzhe@cqtcm.edu.cn PSD model rats， and significantly shorten the cumulative immobility time （P＜0.05）. After treatment with MBD/BDD， the number of genes that changed in rat brain tissue was much higher than that in the FLX group， and there were significant differences in gene profiles among the PSD model group， MBD/BDD group， and FLX group. There were 1 351 differentially expressed genes （DEGs） between the MBD/BDD group and the PSD model group， of which 178 were significantly down-regulated and 1 173 were significantly up-regulated （P＜0.05）. Above 1 351 DEGs were involved in neuronal differentiation， chemical synaptic transmission regulation. They were significantly enriched in axonal guidance， cholinergic synapses and neuroactive ligand-receptor interactions. The top 30 genes in terms of up-regulation in the brain tissue of rats of MBD/BDD group were all associated with neuronal proliferation， development， differentiation， and migration. After MBD/BDD intervention， the expressions of Fezf2， Arx， Ostn， Nrgn genes， brain-derived neurotrophic factor and tyrosine kinase receptor B protein in brain tissue of rats were significantly increased （P＜0.05）. CONCLUSIONS The anti-PSD effect of MBD/BDD may be related to the up-regulation of the expression of genes related to neuronal proliferation， development， differentiation and migration， as well as the promotion of neural structural and functional repair.

Objective:To analyze the efficacy and safety of enzyme therapy in late-onset Pompe disease (LOPD) patients, so as to provide reference for the treatment and prognosis of LOPD.Methods:The effect of α-glucosidase (GAA) on a patient diagnosed with LOPD in the Affiliated Hospital of Jining Medical University was observed and analyzed. Besides, literature related to enzyme therapy in LOPD patients were searched in PubMed, Web of Science, Medline databases. Twenty-one studies containing clinical data from 910 LOPD patients related to enzyme therapy were finally included for analysis.Results:The patient developed muscle weakness since he was 16 years old. The GAA activity in peripheral blood was 0. Electromyography suggested myogenic lesions in both lower extremities. Compound heterozygous mutations of GAA gene were found by next- generation sequencing. Muscle biopsy revealed characteristic vacuolar changes. After eight years of diagnosis, the patient was given enzyme therapy for 18.5 months, 20 times in total. The symptoms of muscle weakness were slightly improved in the early stages of treatment without obvious adverse reactions. Most of the 910 LOPD patients were stabilized or had improved muscular and (or) respiratory function following treatment with GAA.Conclusion:GAA treatment is effective and well tolerated. In patients with advanced severe LOPD, enzyme replacement therapy remains effective even years after onset.

OBJECTIVE: To explore the genetic basis for an infant with neonatal diabetes (NDM) and multiple malformations. METHODS: Genetic variants were detected by next generation sequencing (NGS). Suspected variant was verified by Sanger sequencing. RESULTS: A de novo heterozygous variant, c.1454_1455del(p.K485Rfs), was detected in exon 5 of the GATA6 gene. The variant was undetected in his parents and unreported previously. Bioinformatic analysis predicted the variant to be pathogenic. CONCLUSION The heterozygous variant of c.1454_1455del(p.K485Rfs) of the GATA6 gene probably underlies the disease in this child. Genetic testing can facilitate diagnosis and genetic counseling for NDM.

Objective:To evaluate the efficacy of proximal humerus internal locking system (PHILOS) via the minimally invasive plate osteosynthesis (MIPO) in the treatment of proximal humeral fractures.Methods:This retrospective study analyzed 30 elderly patients with proximal humeral fracture who had been treated by PHILOS via MIPO from September 2016 to March 2020 at Department of Orthopedic Surgery, People’s Hospital of Zhuxi County. They were 19 females and 11 males with an average age of 60.96 years (from 45 to 80 years). All patients were treated by closed reduction. After fracture reduction was confirmed by fluoroscopy, a minimally invasive incision was made below the acromion, with a couple of suture wires reserved at the rotator cuff attachments. A PHILOS plate was inserted at 4 mm lateral to the intertubercular sulcus, with the suture wires passing through the proximal suture holes on the PHILOS. After a lag screw was first screwed up into the compression hole on the PHILOS plate, the crossing suture wires were tightened up to resist the rotator cuff stress and maintain the internal inclination of the humeral head. Kirschner wires were used to temporarily stabilize the reduction. After satisfactory reduction and fine plate positions were confirmed by fluoroscopy, locking nails were screwed up. The internal inclination of the affected humeral head was compared between preoperation and the last follow-up. The therapeutic efficacy was evaluated by the shoulder Neer scoring system, and the visual analogue scale (VAS) pain scores and complications were recorded at the last follow-up.Results:All the 30 patients were followed for 6 to 18 months (average, 12 months). There was no incision infection, neurovascular injury, or internal fixation failure. Anatomical reduction was achieved in 25 patients and functional reduction in 5. The inclination of the humeral head was significantly improved. The VAS scores at the last follow-up averaged 1.9. Follow-up X-ray examination showed that bony union was achieved after 6 to 18 months (average, 9 months) for all patients. At the last follow-up, the inclination angle of the affected humeral head was 130°±5°, significantly improved compared with the preoperative 90°±11.2° ( P<0.05). All patients had good functional recovery of the shoulder. The efficacy was, according to the Neer shoulder scores at the last follow-up, excellent in 22, good in 6 and fair in 2 cases. Conclusions:Treatment of proximal humeral fractures using PHILOS via MIPO technique is suitable for patients with osteoporotic fracture, and may lead to fine therapeutic efficacy.

Objective:To explore the effects of behavior intervention on patients with ischemic cerebrovascular disease recurrence, carotid artery stenosis recurrence, and quality of life after carotid artery stenting implantation.Methods:Sixty patients with carotid stenosis who underwent stenting surgery between January 2017 and July 2018 in Affiliated Hospital of Jining Medical University were recruited.The subjects were randomly divided into behavioral intervention group and control group.The control group was routinely followed up after carotid artery stenting implantation.The behavioral intervention group added home visit, education, guidance of the control and detection of risk factors for cerebrovascular disease of stent implantation.Results:After 12 months of intervention, the incidence of ischemic cerebrovascular disease and the recurrence rate of carotid restenosis in the behavioral intervention group(6.7%, 3.3%) were significantly lower than those in the control group(30.0%, 20.0%) (both P<0.05). Six months after the intervention and 12 months after the intervention, the self-management ability score (intervention group: six months after the intervention (171.20±18.43), 12 months after the intervention (179.90±14.34); control group: six months after the intervention (160.77±13.43); 12 months after the intervention (164.27±14.85)) and quality of SS-QOL score (intervention group: 6 months after intervention (188.47±16.25), 12 months after intervention (203.17±13.84); control group: 6 months after intervention (170.67±15.82); 12 months after intervention (183.80±18.19)of the intervention group were higher than that of the control group, the difference is statistically significant (all P<0.05). Conclusion:Behavioral intervention after carotid artery stenting implantation can effectively reduce the incidence of stroke and the recurrence rate of carotid stenosis and improve the prognosis of patients.The mechanism may be related with that the behavioral intervention can improve the self-management ability and the quality of life of patients with carotid stenosis.
