BackgroundNarrative exposure therapy (NET), an integration of narrative therapy and exposure therapy, has been shown to be effective in relieving the symptoms of post-traumatic stress disorder (PTSD), which can help patients gain a deeper understanding of their trauma and is also considered to be quite safe. PTSD is highly prevalent in children and adolescents, while the effectiveness of NET intervention varies among the subjects. ObjectiveTo systematically evaluate the effectiveness of NET for PTSD in children and adolescents, so as to provide references for the clinical application of NET. MethodsOn August 1, 2022, the Cochrane Library, PubMed, Web of Science, CINAHL, China National Knowledge Infrastructure (CNKI), SinoMed, VIP and Wanfang database were searched from their inception to June 2022. Search was conducted with the use of a combination of medical subject heading and free text terms, and randomized controlled trials relevant to NET for PTSD in children and adolescents were collected. Then the quality of the controlled trials was evaluated according to the Cochrane Collaboration's tool for assessing risk of bias (2011), and Meta-analysis was performed using RevMan 5.4 software. ResultsNine randomized controlled trials involving 394 children and adolescents with PTSD were included. Meta-analysis showed that NET and relaxation therapy reported comparable symptom relief in PTSD patients within 1 to 3 months after intervention (SMD=0.22, 95% CI: -0.84~1.28) and at 6 months after intervention (SMD=0.21, 95% CI: -0.75~1.17), while NET provided greater PTSD symptom relief than routine therapy both within 1 to 3 months after intervention (SMD=-0.66, 95% CI: -1.04~-0.27) and at 6 months after intervention (SMD=-0.77, 95% CI: -1.36~-0.19), with statistically significant differences. Regarding the alleviation of depressive symptoms, the effect was similar between NET and routine therapy within 1 to 3 months after intervention (SMD=-0.39, 95% CI: -0.98~0.21) and at 6 months after intervention (SMD=-0.74, 95% CI: -2.23~0.75). No statistical difference was demonstrated between NET and routine therapy in relieving psychological distress (SMD=-0.54, 95% CI: -2.14~1.07) and suppressing hyperorexia (SMD=-0.17, 95% CI: -0.54~0.19) 1 to 3 months after intervention. ConclusionNET yields a better outcome and a medium- and long-term effectiveness in alleviating symptoms of PTSD in children and adolescents compared with routine therapy, while it does not offer any significant advantages in improving depression symptoms, psychological distress and hyperorexia.

Objective:To explore the urodynamic characteristics of bladder function in patients with abnormal urination after radical hysterectomy of cervical cancer.Methods:In a prospective self-controlled study, a total of 84 patients with cervical cancer and clinical stage of ⅠB to ⅡA, meeting the preoperative inclusion criteria in our hospital from January 2016 to June 2018 were enrolled.All patients were tested for urodynamic testing 1 week before and 6 months after surgery.Patient bladder function status was observed and evaluated before and after surgery and urodynamic examination results were analyzed.Results:Of 84 study cases, the 58 patients developed abnormal urination after radical surgery, there were no urination abnormalities in 26 cases.There was no significant difference in age, clinical stage and pathological diagnosis between patients with and without urination abnormalities.Abnormal urination after radical surgery included difficulty in urinating(55%), frequent urination with a feeling of urination not complete(34%), stress urinary incontinence(7%), and urinary incontinence(4%). Among the 26 patients without urination abnormalities after radical surgery, only one case showed an abnormal urodynamic examination(abnormal bladder sensation). In patients without abnormal urination after surgery, differences in the urodynamic examination findings between pre-and post-surgery were not statistically significant(all P> 0.05). At the same time, in all cases of abnormal urination after radical hysterectomy of cervical cancer, 43 patients(74%)with bladder dysfunction had normal urination pattern before operation, but after operation, the urination abnormality required abdominal pressure.Of the patients with bladder dysfunction after surgery, the maximum flow rate(Qmax)was(12.9±10.3)ml/s, the average flow rate(Qave)was(6.0±4.2)ml/s, the voided volume was(148.0±36.8)ml, voiding time was(32.9±22.1)s, maximum flow time was(11.4±5.0)s, postvoid residual urine was(260.2±219.2)ml, maximal detrusor pressure was(12.1±8.9)cmH 2O, bladder compliance was(16.1±4.3)ml/cmH 2O, normal desire to void was(354.5±204.3)ml, maximal capacity was(587.4±152.5)ml, maximum urethral pressure was(97.6±33.1)cmH 2O, maximum urethral closure pressure was(89.9±36.4)cmH 2O, and function urethral length was(29.6±6.5)mm; In comparison, the above indexes-corresponding values at 1 week before surgery were respectively as follows: the Qmax was(25.1±11.4)ml/s, the Qave was(11.4±6.6)ml/s, the voided volume was(318.6±96.4)ml, voiding time was(29.2±18.5)s, maximum flow time was(6.7±3.9)s, postvoid residual urine was(29.9±21.5)ml, maximal detrusor pressure was(31.9±21.4)cmH 2O, bladder compliance was(78.1±33.9)ml/cmH 2O, normal desire to void was(258.2±185.5)ml, maximal capacity was(335.1±124.9)ml, maximum urethral pressure was(96.4±33.9)cm H 2O, maximum urethral closure pressure was(88.5±35.2)cmH 2O, and function urethral length was(37.2±7.2)mm.It can be seen that Qmax, Qave, voided volume, maximum detrusor pressure, bladder compliance, and functional urethral length in patients with abnormal urination are significantly lower after radical hysterectomy of cervical cancer than before the surgery.While, normal desire to void, maximum capacity, maximum flow time, and postvoid residual urine volume were higher after radical hysterectomy than before surgery( P<0.05). In addition, there was no significant difference in voiding time, maximum urethral pressure and maximum urethral closure pressure between pre-and post-operation.Besides, it is worth noting that there was no significant difference in preoperative urodynamic test results between patients without abnormal urination versus patients with abnormal urination( P>0.05), and the difference in urodynamic test results between the two groups is statistically significant( P<0.05). There was no statistically significant difference in abnormal urination and in urodynamic test results between different clinical stages and between different pathological types( P>0.05). Conclusions:The characteristics of urinary dynamics in patients with abnormal urination after radical hysterectomy of cervical cancer are mainly manifested as decreased bladder sensory function and abnormal detrusor function.And the urodynamic test can provide objective clinical indicators for early diagnosis.

BACKGROUND@#Intra-articular injection is a classic strategy for the treatment of early osteoarthritis (OA). However, the local delivery of traditional therapeutic agents has limited benefits for alleviating OA. Exosomes, an important type of extracellular nanovesicle, show great potential for suppressing cartilage destruction in OA to replace drugs and stem cellbased administration. @*METHODS@#In this study, we developed a thermosensitive, injectable hydrogel by in situ crosslinking of Pluronic F-127 and hyaluronic acid, which can be used as a slow-release carrier to durably retain primary chondrocyte-derived exosomes at damaged cartilage sites to effectively magnify their reparative effect. @*RESULTS@#It was found that the hydrogel can sustainedly release exosomes, positively regulate chondrocytes on the proliferation, migration and differentiation, as well as efficiently induce polarization of M1 to M2 macrophages. Intraarticular injection of this exosomes-incorporated hydrogel significantly prevented cartilage destruction by promoting cartilage matrix formation. This strategy also displayed a regenerative immune phenotype characterized by a higher infiltration of CD163+ regenerative M2 macrophages over CD86+ M1 macrophages in synovial and chondral tissue, with a concomitant reduction in pro-inflammatory cytokines (TNF-a, IL-1b, and IL-6) and increase in anti-inflammatory cytokine (IL-10) in synovial fluid. @*CONCLUSION@#Our results demonstrated that local sustained-release primary chondrocyte-derived exosomes may relieve OA by promoting the phenotypic transformation of macrophages from M1 to M2, which suggesting a great potential for the application in OA.

@#Objective To explore the clinical effect of dl-3-N-butylphthalide(NBP)injection combined with antiplatelet drug therapy and the influence on stroke recurrence of minor stroke patients. Methods A retrospective analysis was performed on 95 patients with minor stroke that admitted to the stoke center of the second affiliated hospital of Harbin Medical University from January to July 2019.It included 45 patients in the combined treatment group (NBP plus antiplatelet treatment group) and 50 patients in the control group (antiplatelet treatment group). The mRS score,NIHSS score and BI of the two groups were analyzed at 14 days,1 month,3 months and 6 months after treatment. The stroke recurrence events at 1 month,3 months,and 6 months after treatment in both groups will be recorded too. We used multivariate analysis to analyze the factors that might influence stroke recurrence in minor stroke patients. Results ①There was no significant difference in baseline information between the two groups(P>0.05),which was comparable. ②At 14 days,1 month,3 months and 6 months after treatment,the mRS scores and NIHSS scores of the patients in the two groups were significantly lower than that at admission,while the Barthel index were significantly higher than that at admission (P<0.01). ③In the combined treatment group at 1 month,3 months and 6 months after treatment,the mRS scores were significantly lower than those in the control group (P=0.033,0.031,0.013). ④The number of the combined treatment group patients with stroke recurrence at 3 months and 6 months after treatment was significantly lower than that in the control group(P=0.033,0.039). ⑤The results of multivariate analysis showed that using NBP was an independent protective factor in stroke recurrence at 3 months (OR=0.060,95%CI 0.005~0.778,P=0.031) and 6 months (OR=0.163,95%CI 0.028~0.968,P=0.028) for minor stroke. Conclusion NBP combined with antiplatelet drugs can significantly improve the neurological function and reduce the stroke recurrence of minor stroke patients.

Objective To investigate the expression level of thymus microRNA-27a-3p in patients with myasthenia gravis (MG) and to explore the pathogenesis of MG.Methods Thymus tissue samples from 36 cases were collected from December 2014 to February 2015 in the Second Affiliated Hospital of Harbin Medical University.Nineteen thymus tissue samples of MG group were collected from department of chest surgery,17 thymus tissue samples of control group were collected from department of chest surgery or congenital heart disease patients from department of cardiac surgery.The expression of microRNA-27a-3p in the thymus from 36 patients was determined by quantitative reverse transcription polymerase chain reaction (qRT-PCR),using U6 as housekeeping control.The Wilcoxon Rank-Sum test was used to analyze the relative expression of microRNA-27a-3p of the two groups.Spearman rank correlation was used to determine the correlation coefficient between microRNA-27a-3p and Quantitative Myasthenia Gravis Score (QMGS).Results (1) The expression level of microRNA-27a-3p in thymus was significantly higher in MG group (0.195(0.049,0.714)) compared with control group (0.045(0.004,0.088),Z =-2.646,P =0.008).(2) Nineteen MG patients were included in the study,out of which 7 were ocular myasthenia gravis (OMG) patients and 12 were generalized myasthenia gravis (GMG) patients.The expression of microRNA-27a-3p in GMG patients (0.493 (0.157,1.123)) was significantly higher than that in OMG patients (0.035 (0.008,0.103),Z =-2.620,P =0.009).(3) There was a positive correlation between the expression of microRNA-27a-3p and QMGS (r =0.576,P =0.010).Conclusions The expression of microRNA-27a-3p in thymus is significantly up-regulated in the patients with MG.MicroRNA-27a-3p may be associated with MG severity and significantly elevated in GMG patients compared with OMG patients.

Objective To investigate the association between myasthenia gravis (MG) and single nucleotide polymorphisms (SNPs) of PTPN22 + 1858C/T,CTLA-4 (+ 49A/G;-1772C/T;-1661A/G),KRAS(rs9226),BCL2(rs4987855) and IGF-1R(rs34804698) genes.Methods Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was adopted to detect the gene types of SNPs in 76 MG patients who were enrolled in the Second Affiliated Hospital of Harbin Medical University from July 2011 to June 2015 and 59 healthy blood donors.Results In MG patients,the frequences of CTLA-4 +49A/G(rs231775) (57.9%) and-1772C/T (rs733618) (43.4%) were higher than that in the healthy controls (22.1%) (x2 =35.252,P =0.000; x2 =4.098,P =0.043).The frequence of CTLA-4 +49A/G in MG patients combined with thymoma (25.6%) was higher than other subgroups (thymic hyperplasia group:13.8%; normal thymus group:18.4%)(x2 =7.564,P=0.006; x2 =7.155,P=0.007).Meanwhile,the frequence of the C-1772 allele was higher in thymoma group (19.7%) compared with other two groups (thymic hyperplasia group:9.86% ; normal thymus group:13.8%) (x2 =5.331,P =0.021 ;x2 =4.411,P =0.036).However,the other SNPs were not associated with the risk of MG.Conclusion There are associations of MG with CTLA-4 + 49A/G and-1772C/T SNPs,but not with PTPN,KRAS,BC12 and IGF-1R SNPs.

<p><b>OBJECTIVE</b>To compare the associated anastomotic complication of cervical esophagogastric anastomosis between stapled and hand-sewn anastomosis in minimally invasive esophagectomy(MIE).</p><p><b>METHODS</b>Clinical data of 203 patients with esophageal cancer receiving combined thoracoscopic and laparoscopic esophagectomy with anastomosis in the neck in our hospital from January 2010 to November 2013 were retrospectively analyzed. All the patients were divided into stapled group(104 patients) and hand-sewn group(99 patients). The incidence of anastomotic leakage and anastomotic stricture between these two groups were compared.</p><p><b>RESULTS</b>There were no significant differences between two groups in gender, age, body mass index, total protein, albumin, and neoadjuvant chemotherapy(all P>0.05). There was no significant difference between the two groups in the incidence of anastomotic leakage [6/104(5.77%) vs. 3/99(3.03%), P>0.05], while the difference in the incidence of anastomotic stricture was significant [10/104(9.62%) vs. 2/99(2.02%), P<0.05]. The time of anastomosis, dieting and hospital stay was (15.5±5.0) min, (5.0±2.8) d and (18.3±5.9) d in stapled group, which was significantly shorter than (28.0±4.5) min, (5.9±1.2) d and (21.8±4.2) d in hand-sewn group(all P<0.05).</p><p><b>CONCLUSION</b>In the minimally invasive esophagectomy, stapled cervical esophagogastric anastomosis is simple and precise, but it is associated with increased risk of anastomotic stricture, therefore the type of anastomosis should be chosen based on the conditions of the patient.</p>
