Objective To observe the influence of optimized nursing process on the clinical effect and quality of life of patients with cerebral infarction received intravenous thrombolysis.Methods Sixty-two cerebral infarction patients with thrombolytic therapy in Panzhihua Central Hospital were treated as control group from January 2013 to June 2014,74 cases cerebral infarction patients with thrombolytic therapy as the observation group from July 2014 to October 2015.The control group received routine nursing,the observation group were given optimized nursing process on the basis of routine nursing.The clinical effect and quality of life were compared between the two groups.Results The triage time,referral time and hospital stay time of the observation group were significantly shorter than the control group,the differences were statistically significant (P ＜0.05).The effective rate in the control group was 70.97％,that of the observation group was 87.84％,the effective rate in observation group was significantly better than that of the control group,the difference was statistically significant (P ＜0.05).Compared with before treatment,the life quality of two groups were significantly improved after treatment,the difference was statistically significant (P＜0.05);after treatment,the quality of life in observation groups were better than that of the control groups,the difference is statistically significant (P＜0.05).Conclusion Nursing process optimization can effectively improve the therapeutic effect for the patients with cerebral infarction intravenous thrombolytic therapy,shorten the treatment time and hospitalization time,and can significantly improve the patient' s quality of life.It is valuable for clinical application.

Visual hallucination(VH)is a common symptom of schizophrenia,the underlying mechanism has not been fully elucidated.It has been found that the dysfunction of dopamine(DA)system,the overactivation of α-amino-3-hydroxy-5-methyl-4-isoxazole-propionate(AMPA)receptor in glutamate system and the dysfunction of γ-aminobutyric acid(GABA)ergic neurons can induce VH in patients with schizophrenia.In addition,abnormalities in brain structural and functional networks and visual networks are also closely related to the occurrence of VH.The purpose of this paper is to review the neurochemistry and nerve injury mechanism of VH in schizophrenic patients to deeply understand the characteristics of VH,and make more accurate judgment in the early diagnosis,condition evaluation and treatment plan of schizophrenic patients.

Objective: To investigate the timing of the laparoscopic cholecystectomy after percutaneous transhepatic gallbladder drainage for acute pyogenic cholecystitis in the advanced age. Methods: The clinical data for 56 advanced age patients with acute pyogenic cholecystitis in the Department of Hepatobiliary Surgery, the 900th Hospital of the Joint Logistics Support Force of People′s Liberation Army from January 2018 to February 2019 were retrospectively analyzed. There were 31 males and 25 females, aged from 70 to 86 years, with average age was (75.52±3.57) years. According to the percutaneous transhepatic gallbladder drainage(PTGD) after laparoscopic cholecystectomy(LC) time interval, all patients were divided into three groups. Patients in the group A(n=12), B(n=21), and C (n=23) performed LC were within 2 months, during 2-4 months, and during 4-6 months, retrospectively. Observation indicators: (1) Surgical situations. The operation and postoperative basic condition of the three groups were compared. (2) Follow-up situations. Patients were followed-up by outpatient examination or telephone interview to detect the postoperative complication in the postoperative three months up to June 2019. Measurement data with normal distribution were represented as (Mean±SD), and comparison multiple groups was done using single factor analysis of variance (AVONA test) , and comparison between groups was done using the t test, and comparison of multiple groups in pairs was done using the SNK-q test, and hierarchical data were analyzed using Kruskal-wallis H test. Count data were analyzed using the chi-square test or Fisher exact probability. Results: (1) Surgical situations: the thickness of gallbladder wall before LC, the rates of converting to laparotomy, the volume of intraoperative blood loss, the operation duration, and the duration of postoperative hospital stay were (0.57±0.04) cm, 50.0%, (95.83±11.45) ml, (107.50±21.90) min, (5.67±3.40) d in the group A, and (0.43±0.03) cm, 9.5%, (69.52±24.59) ml, (71.43±12.16) min, (3.76±2.61) d in the group B, and (0.43±0.05) cm, 39.1%, (68.64±21.89) ml, (77.95±12.88) min, (5.05±2.95) d in the group C, respectively, showing significant differences in the above indicators between the three groups (P<0.05). The thickness of gallbladder wall before LC, the volume of intraoperative blood loss, the operation duration, those in group A were higher than the group B and C (P<0.05), and with no statistically significant different between the group B and C (P>0.05). The rates of converting to laparotomy, the duration of postoperative hospital stay in group B were better than the group A and C (P<0.05), and with no statistically significant different between the group A and C (P>0.05). The thickness of gallbladder wall before LC, the volume of intraoperative blood loss, the operation duration, and the duration of postoperative hospital stay were (0.43±0.03) cm, (46.67±9.82) ml, (67.69±7.77) min, (2.64±0.58) d in the gallbladder wall thickness of successful LC patients, and (0.52±0.04) cm, (123.53±17.30) ml, (134.12±25.51) min, (8.47±0.80) d in the laparotomy patients, respectively, showing significant differences in the above indicators between the two groups (P<0.05). (2) Follow-up situations: 56 patients were followed up and without perioperative death. No complications occurred after 3 months of follow-up. Conclusion Elective surgery that is performed in 2-4 months after PTGD for patients with acute pyogenic cholecystitis in the advanced age can reduce the volume of intraoperative blood loss and the rates of converting to laparotomy, shorten the operation duration and the duration of postoperative hospital stay, which is beneficial to the recovery of patients.

Congenital hydrocephalus is a major neurological disorder with high rates of morbidity and mortality; however, the underlying cellular and molecular mechanisms remain largely unknown. Reproducible animal models mirroring both embryonic and postnatal hydrocephalus are also limited. Here, we describe a new mouse model of congenital hydrocephalus through knockout of β-catenin in Nkx2.1-expressing regional neural progenitors. Progressive ventriculomegaly and an enlarged brain were consistently observed in knockout mice from embryonic day 12.5 through to adulthood. Transcriptome profiling revealed severe dysfunctions in progenitor maintenance in the ventricular zone and therefore in cilium biogenesis after β-catenin knockout. Histological analyses also revealed an aberrant neuronal layout in both the ventral and dorsal telencephalon in hydrocephalic mice at both embryonic and postnatal stages. Thus, knockout of β-catenin in regional neural progenitors leads to congenital hydrocephalus and provides a reproducible animal model for studying pathological changes and developing therapeutic interventions for this devastating disease.
