RESUMEN
Objective To explore the correlation of nerve function and prognosis with serum uric acid(UA),homocysteine(Hcy)and low-density lipoprotein cholesterol(LDL-C)in patients with acute cerebral infarction(ACI)after alteplase intravenous thrombolysis.Methods A total of 220 ACI patients undergoing thrombolysis in Changsha First Hospital ICU between January 2020 and December 2022 were enrolled,and according to mRS score at 3 months after thrombolysis,they were divided into poor prognosis group(mRS score＞2,91 cases)and good prognosis group(mRS score ≤2,129 cases).The serum levels of UA,Hcy and LDL-C were compared between the two groups.The correlation between the three indexes and score of National Institutes of Health Stroke Scale(NIHSS),and their predictive value for poor prognosis were analyzed.Results At 1 and 3 d after thrombolysis,the serum levels of UA,Hcy and LDL-C and NIHSS score were sig-nificantly decreased in both groups,and the serum levels of UA and Hcy and NIHSS score at 3 d after thrombolysis were significantly lower than those at 1 d(P＜0.05).The poor prognosis group had obviously higher serum levels of UA,Hcy and LDL-C and NIHSS score at 1 and 3 d after thrombolysis than the good prognosis group(P＜0.05,P＜0.01).Pearson correlation analysis showed that the serum levels of UA,Hcy and LDL-C were positively correlated with NIHSS score at 1 and 3 d after thrombolysis(P＜0.01).ROC curve analysis indicated that the AUC values of UA,Hcy and LDL-C at 1 d after thrombolysis for predicting poor prognosis were 0.707(95％CI:0.639-0.776),0.800(95％CI:0.739-0.860)and 0.624(95％CI:0.550-0.698),respectively,while the values of them at 3 d after thrombolysis were 0.655(95％CI:0.583-0.726),0.730(95％CI:0.664-0.795)and 0.573(95％CI:0.497-0.649),respectively.Conclusion In ACI patients after thrombolysis,the serum levels of UA,Hcy and LDL-C are increased in those with poor prognosis,and are associated with the severity of nerve injury.The levels at 1 d after throm-bolysis have good predictive value for poor prognosis.
RESUMEN
Fluid resuscitation has been recognized as a main supportive treatment in the early management of acute pancreatitis. Early fluid resuscitation can alleviate local complications and improve prognosis in patients with AP. However, for severe AP, especially for patients with hemodynamic instability, the treatment strategy under the guidance of reasonable and appropriate liquid evaluation indicators is significantly related to the improvement of prognosis. There is still a lack of high quality clinical research evidence on the evaluation of fluid resuscitation. This paper summarizes the latest progress in the evaluation of early fluid resuscitation in severe AP, in order to provide reference for clinical practice.
RESUMEN
Objective:To investigate the Repetitive transcranial magnetic stimulation combined with biofeedback non motor symptoms on clinical effects and serum levels of IL-6,CRP and TNF-α of Parkinson's disease.Methods:84 cases of Parkinson's disease in our hospital were randomly divided into experimental group and control group,with 42 cases in each group.The control group were treated with EMG and EEG biofeedback,while the experimental group were treated with repetitive transcranial magnetic stimulation on the basis of the control group.Then the serum levels of C reactive protein (CRP) and interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α),the non motor symptoms questionnaire (NMSQuest),Parkinson's disease Sleep Scale (PDSS) and Hamilton Depression Scale (HAMD) score in the two groups were observed and compared before and after the treatment.Results:Compared with before treatment,the serum levels of CRP,IL-6 and TNF-α,the NMSQuest and HAMD in the two groups decreased after the treatment,while the PDSS score increased,and the differences were statistically significant (P＜0.05);Compared with the control group,the serum levels of CRP,IL-6 and TNF-α,NMSQuest and HAMD in the experimental group were lower,while the PDSS score was higher,and the differences were statistically significant (P＜0.05).Conclusion:Repetitive transcranial magnetic stimulation combined with biofeedback can reduce the serum levels of IL-6,CRP and TNF-α in patients with Parkinson's disease,which has better clinical effect on the non motor symptoms.

RESUMEN
Objective To investigate the relationship between heme oxygenase-1 (HO-1),glutathione S-transferase (GST) and cerebral atherosclerosis.Methods Cerebralvascular status was assessed with color flow Doppler sonography,transcranial Doppler (TCD),magnetic resonance angiography (MRA)or/and digital subtraction angiography (DSA) in patients with cerebral atherosclerosis (mild,moderate,and severity).Serum HO-1 and GST were measured with enzyme-linked immunosorbent assay (ELISA).Results In comparison between case and control groups,there was significant difference in age,hypertension,cerebral infarction,uric acid,and HO-1 (P =0.041,0.008,0.000,0.036,and 0.001).The level of serum HO-1 in the severe atherosclerosis was lower than that in the mild and moderate atherosclerosis (P =0.000 and 0.002).Logistic regression was used to find the association of HO-1 and the degree of cerebral atherosclerosis (P =0.000).Conclusions HO-1 might be related to cerebral atherosclerosis.
RESUMEN
Objective To evaluate the efficacy of continuous lumbar plexus block (CLPB) combined with a bolus dose added at night for postoperative analgesia in patients undergoing hip arthroplasty.Methods Sixty ASA Ⅰ or Ⅱ patients of both sexes,aged 51-75 yr,weighing 47-77 kg,with body height 150-180 cm,scheduled for hip arthroplasty,were randomized to receive either CLPB (group CLPB) or patient-controlled intravenous analgesia (PCIA) (PCIA group) for postoperative analgesia (n =30 each).Spinal anesthesia was performed at L3,4 interspace.Postoperative analgesia was performed at 30 min before the end of surgery.PCIA solution contained morphine 100 mg in 100 ml of normal saline.The PCA pump was set up with a 2 mg bolus dose and a 5 min lockout interval.CLPB solution contained 0.125 ％ ropivacaine hydrochloride 200 ml.CLPB pump was set up to deliver a 4 ml bolus dose with a 30-min lockout interval and background infusion at 8 ml/h after a loading dose of 0.125％ ropivacaine 30 ml.In addition the patients received 0.25％ ropivacaine 30 ml at 8 o' clock every night after surgery in group CLPB.VAS scores at rest and during activity were recorded at 6,12,18,24,30,36,42 and 48h after operation.The side effect such as nausea and vomiting,pruritus and urinary retention were recorded within 48 h after operation.The patient' s satisfaction was assessed.The maximal hip flexion and abduction ranges of motion were recorded at 12,24,36 and 48 h after operation.The times of sleep interruption resulted from pain during nighttime were also recorded.Results Compared with group PCIA,the VAS scores during activity,severity of nausea and vomiting,pruritus and urinary retention,and times of sleep interruption resulted from pain during nighttime were significantly decreased,and the overall satisfaction score and maximal hip flexion and abduction ranges of motion were increased in group CLPB (P ＜ 0.05).Conclusion CLPB combined with a bolus dose added at night can provide better efficacy for postoperative analgesia in patients undergoing hip arthroplasty than PCIA,with fewer complications.

Objective Linkage analysis were performed in 2 pure Chinese paroxysmal kinesigenic dyskinesia families to localize the locus of them. Method Microsatellites markers corresponding to pericentrometric region of chromosome 16 were used in parametric and nonparametrie linkage analysis for 27 members in the 2 pedigrees, haplotypes were constructed subsequently. Result The maximum LOD score and NPL score in the 2 families were all negative, P values were significantly larger than 0.05.No haplotype segregated with PKD phenotype was found. It showed no evidence of association with known PKD loci in both pedigrees, providing evidence for a novel PKD locus. Conclusion PKD is heterogeneous, a novel PKD locus may be in pure Chinese pedigrees.
