Objective To evaluate the PDCA cycle on the rehabilitation of postoperative patients with anal fistula, aiming at improving the recovery of patients and preventing recurrence. Methods 144 postoperative patients of anal fistula were randomly divided into the observation group and the control group with 72 cases in each group. The observation group received intervention based upon the PDCA cy-cle, and the control group was given the traditional oral propaganda. The recovery time, recurrence rate, mastering of education content and self-control ability were compared in the two groups using t test and χ2 test. Results The mastering level of education content and the self-management skills in the observation group were superior to those of the control group. After 3 to 24 months of follow-up, the observation group showed shorter recovery time and less recurrence rate than that of the control group. Conclusions Nurs-ing intervention based upon PDCA cycle can strengthen the patients' mastering of related knowledge, pro-mote the recovery, reduce recurrence rate and improve the patients' quality of life.

Objective:To report 2 young infants of sodium channel related epilepsy with SCN2A gene mutation, and to discuss the clinical characteristics of the disease and the efficacy and safety of lacosamide combined with the literature.Methods:Corresponding information of 2 children hospitalized in the Department of Neurology of Hunan Children′s Hospital in July 2021 and October 2021 was collected, including the symptoms, comprehensive physical examination, blood, cerebrospinal fluid, imaging, electrophysiological examination, diagnosis and treatment process, response to treatment and other clinical data, as well as the sequencing results of the whole exome of the children. The efficacy and safety of lacosamide were analyzed, and the related literatures of the Biomedical Literature Database, Wanfang Data Knowledge Service Platform and Chinese Knowledge Infrastructure Database were searched and reviewed.Results:Both of the 2 cases were girl. Their onset age was within 3 months. The initial symptoms were frequent convulsions and backward development. There was no structural abnormality in the head image. The convulsions could not be controlled according to conventional multidrug treatment. The seizures were quickly controlled with lacosamide. Now they have been followed up for 6 months. No obvious adverse reactions were found. Case 1 gene test results showed the SCN2A gene (chr2:166152333-166246334) heterozygous deletion, SCN1A gene (chr2:166847754-16693013) heterozygous deletion, the deletion size being about 5.72 Mb. Case 2 gene test results showed new missense mutation of SCN2A (c.1285G>A, p.Glu429Lys). There were dozens of seizures every day. They were treated with valproic acid, oxcarbazepine and levetiracetam successively. The seizures could not be controlled. Three focal seizures originated in the left temporal region were detected by electroencephalogram. There was no recurrence on the third day after adding lacosamide, and there was no attack after 5 months of follow-up. No obvious adverse reactions were found during follow-up.Conclusions:Sodium channel related epileptic encephalopathy often starts early, has frequent seizures, and can be accompanied by backward psychomotor development at the same time. The slow sodium channel blocker lacosamide has good efficacy and safety in the treatment of sodium channel-related epilepsy with SCN2A gene mutation or combined SCN1A gene mutation.

Objective To assess the effect and safety of tranexamic acid used in spinal surgery by means of a systematic review and Meta-analysis.Methods Literatures were retrieved from Ovid (1999 March to 2017 March),PubMed (1999 March to 2017 March),Sciencedirect(1999 March to 2017 March),CNKI,VIP and Wangfang.All the related literatures were checked on the selection criters.Only the retrospective randomized controlled trails (RCTs) with high quality (Jadad score ≥ 3) and with double-blind process were enrolled.The relevant data were analyzed using RevMan 5.0 to compare about difference of intraoperative and postoperative blood loss,transfusion rate,postoperative activated partial thromboplastin time (APTT),postoperative hematocrit (Hct),postoperative hemoglobin (Hb) and thrombotic complications between tranexamic acid group and placebo group.Results Only 8 high quality RCTs met the inclusion criteria.The use of tranexamic acid in spinal surgery significantly reduced the intraoperative blood loss(SMD =-0.33,95％ CI-0.12,0.54,P ＜0.01),and reduced the rate of transfusion(OR =0.55,95％ CI0.37,0.82,P ＜0.01).TXA group had a significant decrease of APTT at 24 h after surgery(MD =1.45,95％ CI-2.92,0.01,P ＞ 0.05),a significant increase of postoperative Hct (MD =1.55,95％ CI 0.45,2.65,P ＜ 0.01) and an enhancement of Hb (MD =0.49,95％ CI 0.20,2.65,P ＜ 0.01) compared with placebo group.The difference of thrombotic complication rates risks between tranexamic acid group and placebo group was not statistically significant(OR =1.01,95％ CI 0.06,16.52,P ＞ 0.05).Conclusion The use of tranexamic acid can significantly reduce intraoperative blood loss and the rate of transfusion during spinal surgery,without increase of postoperative deep vein thrombosis or pulmonary embolism.

Objective:To study the efficacy of laparoscopic limited anatomical hepatectomy (LLAH) for hepatocellular carcinoma (HCC) within the right anterior section.Methods:The clinical data of 144 patients with HCC confined in the right anterior section undergoing hepatectomy at the First Affiliated Hospital of Army Medical University from January 2015 to December 2022 were retrospectively analyzed, including 122 males and 22 females, aged (54.5±9.7) years. Patients were divided into LLAH ( n=27), laparoscopic anatomical hepatectomy (LAH, n=69), and laparoscopic non-anatomical hepatectomy (LNAH, n=48). Propensity score matching was used to compare the operative time, postoperative hospital stay, postoperative complications, serum total bilirubin and albumin, and the prognostic indicators such as tumor-free survival (DFS) rate and cumulative survival rate between the groups. Results:After propensity score matching, there were 26 cases each in LLAH and LNAH group. There was no significant difference in operative time, intraoperative blood loss and postoperative hospital stay between LLAH group and LNAH group (all P<0.05). The total bilirubin and albumin in LLAH on the third day after operation were [ M( Q1, Q3)] 24.1(20.9, 29.1) μmol/L and (35.8±2.9) g/L, better than those in LNAH group 39.3(33.2, 57.0) μmol/L and (33.9±2.5) g/L, respectively. The 1- and 3-year DFS rates in LLAH group were 92.3% and 57.7%, higher than those in LNAH group (80.8% and 19.2%) (all P<0.05). After propensity score matching, there were 25 patients each in LLAH and LAH group. The operative time, postoperative hospital stay and postoperative complications of LLAH group were lower than those of LAH group, and the liver function parameters of LLAH group was also better than those of LAH group (all P<0.05). There was no significant difference in DSF rate between the two groups LLAH group and LAH group ( χ2=0.10, P=0.800). Conclusions:The perioperative outcome of LLAH for HCC within the right anterior section are similar to that of LNAH and better than that of LAH. The DFS of LLAH were better than that of LNAH and similar to that of LAH.

Objective To investigate the effect of bone marrow mesenchymal stem cells(BMSCs)on the inflamma-tory response of lipopolysaccharide(LPS)induced acute lung injury(ALI)in mice.Methods 32 SPF KM mice,aged 4 weeks were randomly divided into four groups,control group,LPS group,dexamethasone treatment group(LPS+DEX)and BMSCs treatment group(LPS+BMSCs).The latter three groups were injected with LPS by tra-cheal puncture to establish mouse ALI model 24 h after modeling,BMSCs isolated from the femur of mice were in-jected into the caudal vein,and DEX were injected into caudal vein at the same time in LPS+DEX group for 3 consecutive days.On the 4th day after cell transplantation or 24 h after DEX injection,the survival quantity of mice was recorded,lung function was detected,and the wet/dry weight ratio(W/D)of lung was measured.Then in-flammatory cells in bronchoalveolar lavage fluid(BALF),lung pathological changes and serum inflammatory cyto-kines were collected.Green fluorescent protein(GFP)staining was used to observe the homing of BMSCs in lung tissues.The mRNA and protein expression of TLR4,MyD88 and NF-κB in lung tissues were detected by RT-PCR and Western blot assay respectively.Results Compared with the control group,LPS model group showed de-creased lung function,significantly increase in the W/D weight ratio of lung,inflammatory cytokines in serum and inflammatory cells in BALF,and severe damage in lung tissue.Compared with LPS group,LPS+DEX group and LPS+BMSCs group showed improved lung function,reduced lung tissue damage,significantly decrease in the W/D weight ratio of lung,inflammatory cytokines in serum and inflammatory cells in BALF.And the expression of TLR4-MyD88-NF-κB signaling pathway-related genes and proteins decreased,the survival quantity increased.Conclusion Homologous BMSCs transplantation can effectively treat LPS-induced acute lung injury,and the mechanism may be related to the regulation of TLR4-MyD88-NF-κB signaling pathway and the reduction of inflam-matory response.These findings provide the experimental basis for BMSCs homologous transplantation for ALI.
