Objective To explore the diagnostic value of magnetic resonance DKI parameters and serum levels of tumor necrosis factor-alpha(TNF-α)and interleukin-1α(IL-1α)in Alzheimer's disease(AD).Methods From July 2020 to July 2022,60 patients with Alzheimer's disease in our hospital were selected as the observation group and 60 healthy elderly people over 60 years old as the control group.All patients underwent routine MRI sequence examination,measured DKI parameters,and detected serum TNF-α and IL-1α levels by ELISA.Results The MD value of each brain area was significantly increased in alzheimer's disease patients.FA of white matter,hippocampus and substantia nigra decreased in temporal and parietal cortex,while FA of caudate nucleus,red nucleus and dentate nucleus increased.RK of white matter,hippocampus and thalamus in temporal and parietal cortex decreased significantly,while RK in substantia nigra increased significantly.AK of white matter,thalamus,dentate nucleus and substantia nigra in temporal and parietal cortex were significantly decreased.The MK in white matter,hippocampus and thalamus of temporal and parietal cortex decreased significantly,while the MK in caudate nucleus and substantia nigra increased significantly.The serum levels of homotype hemisoline and acetylcholinesterase increased significantly.Conclusion Combined magnetic resonance DKI parameters and detection of serum TNF-α and IL-1α levels have certain diagnostic and predictive value for the occurrence of Alzheimer's disease.

Objective To summarize the clinical phenotype and gene mutation characteristics of early epileptic encephalopathy caused by STXBP1 gene mutation and the application of second-generation gene sequencing in etiological diagnosis.Methods Retrospective analysis of clinical characteristics,gene test results,treatment and efficacy of 19 children with epileptic encephalopathy with genetic diagnosis of STXBP1 gene mutation who were seen in the Department of Pediatrics of the Second Hospital of Zhejiang University School of Medicine from January 2017 to January 2021.Results The disease started within 1 month after birth in 15 children(78.9%).All 19 children had significant electro-encephalo gram(EEG)changes:13 cases of burst suppression(68.4%)and high arrhythmia in 12 cases(63.2%).A total of 18 pathogenic variants were detected in 19 children,all of them new,of which 7 loci have not been reported so far.Five children were diagnosed with Otahara syndrome,five with infantile spasms,and nine with an epileptic syndrome that could not be classified.At a follow-up of 6 months to 4 years and 5 months,1 case was discontinued,5 cases had complete remission of seizures,6 cases had partial remission,and 7 cases were ineffective.8 of the 12 children with seizure remission or control were treated effectively with combination levetiracetam,4 of the 6 children with spasms responded with the addition of vigabatrin,and 7 presented with drug refractory epilepsy.All 19 children had varying degrees of developmental delay.Conclusion Mental-motor retardation and recurrent seizures are the main,independent phenotypic features of STXBP1-encephalopathy,STXBP1 gene variants are predominantly de novo variants,second-generation gene sequencing diagnosis helps in the early diagnosis of STXBP1-encephalopathy,levetiracetam and aminocaproic acid may be partially effective in controlling seizures in STXBP1-encephalopathy,and ketogenic diet provides new ideas for early-onset epileptic encephalopathy treatment provides a new idea.

Objective To analyze the clinical effect of ultrasound-guided quadratus lumborum block(QLB)and erector spinae plane block(ESPB)in elderly patients with laparoscopic colorectal cancer surgery.Methods A total of 75 elderly patients who underwent elective laparoscopic radical resection of colorectal cancer in wenzhou central hospital,from August 2021 to March 2022 were selected and divided into quadratus lumborum group(group Q,n=25),erector spinae muscle group(group E,n=25)and group C(n=25).Group Q received QLB combined with general anesthesia,group E received ESPB combined with general anesthesia,the group C was given tracheal intubation with total intravenous general anesthesia.The perioperative anesthesia and analgesic dosage,postoperative recovery quality,resting and cough visual analogue scale(VAS)scores were compared among the groups.Results In contrast to the group C,the number of effective PCIA compressions,the dose of sufentanil,and the analgesic rescue rate were significantly decreased in groups Q and E(P<0.05);In contrast to the the group C,the spontaneous breathing,eye opening and tracheal extubation time of patients in group Q and group E were apparently shortened(P<0.05),and patients in group Q and group E recovered indoor nausea and vomiting,lethargy,restlessness and respiratory depression The number of cases was apparently reduced(P<0.05);at each time point from 2 to 48 hours after operation,compared with the group C,the VAS scores at rest and cough in groups Q and E were apparently decreased(P<0.05).However,there was no significant difference in the above indicators between the group Q and the group E(all P>0.05).Conclusion Ultrasound-guided QLB and ESPB for laparoscopic colorectal cancer surgery can both improve the quality of recovery and achieve satisfactory analgesia in elderly patients.

Objective This study focused on the low voltage and low concentration contrast agent technology in vascular imaging of stroke patients.Methods Totally144 patients of ischemic stroke confirmed from January 2022 to January 2023 were enrolled.They were divided into four groups according to different imaging methods:conventional group(tube voltage 120kV,iodine concentration 370mgI/ml),low voltage group(tube voltage 80kV,iodine concentration 370mgI/ml),low concentration group(tube voltage 120kV,iodine concentration 320mgI/ml)and dual-low group(tube voltage 80kV,iodine concentration 320mgI/ml),the post-processing technology adopted ASiR algorithm for 3D reconstruction.Then to compare contrast signal-to-noise ratio(CNR)and signal-to-noise ratio(SNR)of the reconstructed image,image quality score,CT values of internal carotid artery(ICA),anterior cerebral artery(AA)A1,middle cerebral artery(MA)M1,posterior cerebral artery(PA)P1,vertebral artery(VA)and basilar artery(BA),mean iodine intake and radiation dose parameters including volume CT dose index(CTDIvol)and dose length product(DLP).Results The CNR and SNR values in dual-low group were significantly less than the other three groups(P<0.05),while image quality score and CT value of each artery were no differences among the four groups(P>0.05).What's more,CTDIvol,DLP and iodine intake volume in dual-low group were significantly less than the others(P<0.05).Conclusion The dual-low technology scanning could obtain satisfactory head and neck CT angiography for stroke patients.

Objective To observe the effect of high-frequency repetitive transcranial magnetic stimulation on hemiplegic shoulder pain during convalescence of stroke.Methods A total of 40 patients with hemiplegic shoulder pain during convalescing stroke who were hospitalized in Rehabilitation Medicine Department of Jiaxing Second Hospital from January 2021 to June 2022 were selected and randomly divided into treatment group(rTMS group)and control group(sham rTMS group),with 20 cases in each group.Both groups were given anti-inflammatory and analgesic drugs and conventional rehabilitation treatment.On this basis,the treatment group was combined with rTMS treatment(stimulation frequency was 10.0Hz,stimulation intensity was 80%resting motor threshold,stimulation time was 10s,interval was 50s,total treatment time was 20 minutes,once a day from Monday to Friday,continued treatment 2 days apart,20 times as a course of treatment,a total of 4 weeks),while the control group received sham rTMS.Before treatment,2 and 4 weeks after treatment,numerical pain rating scale(NPRS)was used to assess the degree of shoulder pain,passive shoulder range of motion was measured by protractor,upper limb motor function of hemiplegic side was assessed by Fugl Meyer assessment upper extremity(FMA-UE),and the ability of daily living activities was assessed by modified Barthel index(MBI).Results After treatment,NPRS score of shoulder pain in 2 groups was significantly decreased compared with before treatment(P<0.001),passive shoulder motion and Fugl-Meyer upper limb motor function were significantly improved compared with before treatment(P<0.001),and the treatment group was significantly better than the control group,the difference between groups was statistically significant(P<0.05).The modified Barthel index in 2 groups was significantly improved compared with before treatment(P<0.001),but there was no statistical significance between 2 groups(P>0.05).Conclusion 10.0Hz high-frequency repetitive transcranial magnetic stimulation can significantly relieve hemiplegic shoulder pain during the convalession of stroke,improve the passive range of motion of the affected shoulder,and improve the upper limb motor function of the affected side,but the effect is not significant in improving the ability of daily living activities.

Objective To explore the effect of endoscopic hemostasis combined with octreotide on hemodynamics and clinical outcome of patients with acute upper gastrointestinal bleeding.Methods From January 2019 to June 2022,80 patients with acute upper gastrointestinal bleeding in Xinyu Yinhe Hospital of Jiangxi Province,and according to random number table method,40 cases each in the control group and 40 cases in the observation group.The control group was treated with conventional endoscopic,while the observation group was treated with octreotide on this basis.The clinical efficacy,high sensitivity C-reactive protein(hs-CRP),cortisol(Cor)levels and hemodynamic changes[cardiac output(CO),heart rate(HR),mean arterial pressure(MAP)]were compared between the two groups.Results The total effective rate of the observation group was significantly higher(P<0.05).After treatment,hs-CRP and Cor levels in 2 groups were lower than before,and hs-CRP and Cor levels in observation group were significantly lower(P<0.05).After treatment,the levels of CO,HR and MAP in the two groups were decreased,and the levels of CO,HR and MAP in the observation group were significantly lower(P<0.05).Conclusion Endoscopic hemostasis combined with octreotide can promote the hemodynamic indexes of patients with acute upper gastrointestinal bleeding to return to normal,improve the levels of hs-CRP and Cor,and improve clinical efficacy.

Objective To explore the effect of different types of helicobacter pylori(Hp)on carotid atherosclerosis(CAS)and the efficacy of rosuvastatin.Methods Totally 346 subjects were examined in the physical examination center of our hospital from February 2020 to June 2022.According to the results of 14C urea breath test and Hp antibody typing,they were divided into 102 cases of type Ⅰ Hp infection group,79 cases of type Ⅱ Hp infection group and 165 cases of Hp negative group,inflammatory factors,blood lipids and carotid artery ultrasound were also examined.All subjects with carotid atherosclerosis were instructed to treat with rosuvastatin 10mg/d,and the level of low density lipoprotein cholesterol(LDL-C)was rechecked after 4 weeks.Results There were significant differences in high sensitivity C-reactive protein(hs-CRP),IL-6 and tumor necrosis factor-α(TNF-α)between the three groups(P<0.05).Compared with Hp negative group,cholesterol(TC)and LDL-C in type Ⅰ and type Ⅱ Hp infection groups were significantly increased,while high density lipoprotein cholesterol(HDL-C)in type Ⅰ Hp infection group was significantly decreased;compared with type Ⅱ Hp infection group,LDL-C in type Ⅰ Hp infection group was significantly increased,and HDL-C was significantly decreased(P<0.05).The detection rate of stable plaque and unstable plaque in Hp positive subjects was significantly higher than that in Hp negative subjects(P<0.05);the detection rate of stable plaque and unstable plaque in type Ⅰ Hp infected subjects was significantly higher than that in type Ⅱ Hp infected subjects(P<0.05);after adjusting for age,hypertension,diabetes and other risk factors,it was still an independent risk factor of carotid atherosclerotic plaque vulnerability.After 4 weeks,the LDL-C level of CAS subjects in the three groups before and after treatment was significantly different(P<0.05).Compared with the type Ⅰ Hp group,the LDL-C level of CAS subjects in the Hp-negative group was significantly lower(P<0.05).Conclusion Hp infection,especially type Ⅰ Hp infection,is related to dyslipidemia,stimulation of inflammatory reaction and instability of carotid plaque,affecting the efficacy of lipid-lowering drugs.
