Living systematic review (LSR) is a systematic review methodology that incorporates regular updates to integrate new evidence, aiming to rapidly reflect the latest research findings. Although LSRs are increasingly adopted in clinical fields, their reporting quality remains inconsistent and lack of standardized guidelines. To standardize LSR reporting, the PRISMA 2020 statement has released an extension checklist (PRISMA-LSR). This paper describes the background of PRISMA-LSR release and main revisions, and interprets it with examples, with the goal of guiding future LSR research and enhancing reporting quality.

Objective To investigate the efficacy and safety of cognitive behavioral therapy （CBT） in the treatment of functional seizures （FS）. Methods Databases including PubMed （MEDLINE）， EMBASE， and the Cochrane Library were searched for randomized controlled trials （RCTs） on CBT in the treatment of FS published from January 2001 to October 2024. Jadad score was used to assess the quality of studies， and stata16 software was used to perform the meta-analysis. Results Four RCTs involving 463 patients were included in this meta-analysis. The analysis showed that CBT could reduce the frequency of FS by ≥50% （OR=0.57， 95%CI 0.36~0.78， P<0.001）， achieve complete remission of seizures （OR=1.83， 95% CI 1.09~3.05， P=0.021）， improve the degree of satisfaction among patients （MD=1.12， 95%CI -2.28~0.04， P=0.050）， and enhance the quality of life and work （OR=0.50， 95%CI 0.47~0.52， P<0.001）. Conclusions While CBT can help achieve full remission in FS， more research is needed to confirm its effectiveness in reducing episodes by over 50% and improving patients’ quality of life， family functioning， social adaptability， and psychological well-being.

Objective To explore the molecular mechanism of Atractylodes macrocephala in the treatment of Ulcerative colitis(UC)based on network pharmacology,and verify it with animal experiments.Methods The active components of Atractylodes macrocephala was screened from the TCMSP database,the TCM-ID database,and in combination with relevant references,and the corresponding targets were obtained through Swiss database.The relevant targets of UC were obtained from GeneCards database,construct the"drug-component-target-disease"network diagram and"pathway-active ingredient-target"network diagram and draw PPI network diagram;GO function enrichment analysis and KEGG signal pathway annotation analysis were carried out.Autodock software is used for molecular docking of active components and targets.Then,the experimental validation of the network pharmacology prediction was carried out.The mouse UC model was induced by dextran sodium sulfate(DSS).The pathological changes of the colon tissue,the number of goblet cells,and the positive expression of inflammatory factorswere detected by HE staining,AB-PAS staining and immunohistochemistry in colon tissue of UC mice.Results The results have shown 30 active ingredients including atractylolactone I,II and III were screened,and 591 corresponding targets were obtained,of which the key target was IL-1β、TNF-α and so on.Molecular docking show that the core components had good binding affinity with the key targets.And the results of animal experiments showed that the alcohol extract of Atractylodes macrocephala could significantly increase the colon length,reduce the DAI score,improve the pathological changes of colon tissue of UC mice,increase the number of goblet cells,and inhibit the expression of IL-1β,TNF-α in colon tissue.Conclusion This study indicated that Atractylodes macrocephala could regulate the release of inflammatory factors through multiple components,multi-target and multi-channel,which could inhibit inflammatory reaction and play a role in improving UC.

Objective To evaluate the long-term safety of related kidney donors after unilateral nephrectomy.Methods A total of 91 related donors who received nephrectomy in our hospital from 2006 to 2011 were followed up for at least 10 years by outpatient,telephone,or WeChat.During the follow-up period,the serum creatinine,serum uric acid,blood urea nitrogen,estimated glomerular filtration rate(eGFR),hematuria,urinary protein,blood pressure,blood glucose and blood lipids of the donors were detected,and the changes before and after nephrectomy were analyzed.Results At 1 month after operation,the levels of serum creatinine,blood urea nitrogen and serum uric acid of the donor were significantly higher than those before operation(all P＜0.05),but still within the normal range.The patients were followed up for 1,3,5 and 10 years after operation.Compared with 1 month after operation,the serum creatinine,blood urea nitrogen and serum uric acid were relatively stable(all P＞0.05).The eGFR of donors of different ages remained relatively stable for a long time after operation.There were 3 cases of endoscopic hematuria and 4 cases of proteinuria after surgery,and these symptoms were relieved after rest and symptomatic treatment.Ten(11.0%)donors developed hypertension 5(5.5%)developed hyperlipidemia,and 5(5.5%)developed diabetes mellitus.No patient died.Conclusion Nephrectomy is safe and feasible for healthy related donors.To ensure the safety of the donors,comprehensive evaluation before nephrectomy and regular follow-up after nephrectomy are essential.

Objective To investigate the effects of dexmedetomidine used to supplement analgesia on sleep quality in elderly patients after abdominal surgery.Methods Ninety-eight elderly patients,56 males and 42 females,aged 65-80 years,BMI 18.5-25.0 kg/m2,ASA physical status Ⅱ or Ⅲ,who un-derwent elective abdominal surgery under general anesthesia were selected and divided into two groups using the random number table method:dexmedetomidine group(group D)and control group(group C),49 pa-tients in each group.The two groups were used the same drugs for induction and maintenance of anesthesia,with different analgesic formulas after surgery.Analgesia formula in group C was sufentanil 2 μg/kg,tropi-setron 4 mg,and normal saline to 100 ml,and in group D was sufentanil 2 μg/kg,dexmedetomidine 5μg/kg,tropisetron 4 mg,and normal saline to 100 ml.In the form of questionnaire survey,consensus sleep diary(CSD)was used to record the patient's sleep latency,number of awakenings and duration of waking after sleep 1 day before surgery and 1 day,3,and 7 days after surgery,and then the actual sleep time and sleep efficiency were calculated.The patient's venous blood was collected at 5:00 to 7:00 in the morning to detect serum melatonin,interleukin-6(IL-6),interleukin-1β(IL-1β)and tumor necrosis factor(TNF-α)concentration.Extubation time,the incidence of cough,agitation,respiratory depression,postoperative bradycardia,nausea and vomiting,lethargy,urinary retention,and other adverse reactions were recorded.Results Compared with group C,the sleep latency was significantly reduced,the actual sleep time and the sleep efficiency were significantly increased 1 day,3,and 7 days after surgery(P＜0.05).Compared with group C,the concentration of postoperative melatonin in group D were significantly increased 1 day,3,and 7 days after surgery(P＜0.05),the concentration of IL-6,IL-1β and TNF-α in group D were significantly reduced 1 and 3 days after surgery(P＜0.05).There was no significant difference in the incidence of ad-verse reactions between the two groups.Conclusion Patient-controlled intravenous analgesia with dexme-detomidine assisted in elderly patients after abdominal surgery can improve sleep efficiency,increase sleep time and postoperative sleep quality,which may be related to the changes of melatonin and inflammatory factors after surgery.

Objective:To explore the clinical characteristics and risk factors of pediatric kidney transplantation (KT).Methods:From January 1, 2010 to September 30, 2022, retrospective analysis was performed for the relevant clinical data of 81 pediatric recipients of primary KT at Organ Transplant Center of Shanghai Changzheng Hospital. The occurrences of acute rejection (AR) ,delayed graft function (DGF), infection, myelosuppression, tumor and other complications were observed within 1 year post-KT. They were grouped according to whether or not AR/DGF occurred. Univariate analysis speculated the effect of AR and DGF on renal function at 1 year after transplantation. Binary Logistic regression was employed for examining the risk factors related to AR/DGF.Results:During follow-ups, transplanted kidney was removed due to an embolization of renal vessels and dialysis resumed (n= 5). One child had failed graft due to the recurrence of original disease and dialysis resumed. The remaining 75 children had an excellent recovery of graft function. At the end of follow-ups, survival for transplant recipients and transplanted kidneys was 100% (81/81 ) and 92.6% (75/81) respectively. 23 patients (28.4%) developed DGF, including 20 child recipients of C-I donors. Among DGF recipients, 21 (91.3%) were immune induced with anti-CD25 humanized monoclonal antibody and 2 (8.7 %) with porcine antihuman lymphocyte immunoglobulin (pALG). Within the first year post-KT, 13 patients (16.1%) developed AR, including 11 child recipients of C-I donors. Induction was made with anti-CD25 humanized monoclonal antibody (n=8), pALG (n=4) and anti-human T lymphocyte rabbit immunoglobulin (n=1). And 12 cases were reversed with MP (methylprednisolone) shock therapy while another ineffective case was rescued by an intravenous infusion of rATG (rabbit anti-human thymocyte immunoglobulin). During postoperative follow-ups, 14 (17.3 %) KT recipients had an onset of pulmonary infection (n=7), upper respiratory tract infection (n=3), urinary tract infection (n=5), gastrointestinal infection (n=2) and abdominal cavity infection (n=1). The causative pathogens were bacteria (n=14) and viruses (n=4). Among 7 cases (8.6%) of myelosuppression, there were leukopenia (n=6) and thrombocytopenia (n=1 ). During 1-year follow-ups, no malignancy occurred. At the last follow-up, blood creatinine was (72.79±21.07) μmol/L in non-AR/DGF recipients. For AR/DGF recipients, blood creatinine levels were (68.83±10.78) and (74.20±18.70) μmol/L. There was no significant inter-group difference ( F=0.14, P=0.87). In groups with and without DGF, the incidence of bone marrow suppression in the children with DGF was significantly higher (21. 74 %) than that in the untreated group (3.45%), with a statistically significant difference ( P=0.02). However, there was no statistically significant difference in the age, sex, donor source, infection, and types of immune-induced drugs in AR, DGF occurrence and no occurrence group. logistic Regression analysis showed that immunoinduction therapy with lymphocyte inhibitor ( OR=0.074, 95 %CI: 0.009-0.0643, P=0.018) and bone marrow suppression ( OR=0.045, 95%CI: 0.004-0.515, P=0.013) were risk factors for DGF. Conclusion:KT in children may obtain decent outcomes. Immunoinduction therapy with lymphocyte inhibitors and occurrence of myelosuppression are risk factors for postoperative DGF. The occurrence of AR/DGF in early postoperative period does not affect the level of kidney function in children at 1 year post-KT. It is recommended to closely follow up and accumulate experiences for optimizing long-term outcomes.

Objective:To investigate the effects and significance of acute and chronic trauma on brain degree centrality (DC) in patients with post-traumatic stress disorder (PTSD) who lost their only child at resting state.Methods:Retrospectively, the study enrolled a total of 51 parents with PTSD, including 35 PTSD parents whose children was lost in emergencies (acute bereaved PTSD group) and 16 PTSD parents whose children was lost of chronic causes such as diseases (chronic bereaved PTSD group). Fifty local adults were also included as healthy controls (HC group). The clinical administered PTSD scale(CAPS) was used to evaluate the severity of the subjects' clinical symptoms.Resting-state functional magnetic resonance imaging(fMRI) data of all subjects were collected and DC values were calculated.SPSS 22.0 software was used for statistical analysis.Covariance analysis was performed among three groups, while post hoc was performed between any two groups.What's more, correlation analyses were utilized between abnormal brain regions and the scores of CAPS.Results:Significant group effects were found in multiple regions, including the right inferior temporal gyrus (MNI: x, y, z=66, -27, -21), right temporal pole (MNI: x, y, z=54, 15, -9), right orbital inferior frontal gyrus (MNI: x, y, z=42, 21, -15), bilateral medial superior frontal gyri (MNI: right x, y, z=6, 63, 12; left x, y, z=-3, 60, 18), left inferior parietal angular gyrus (MNI: x, y, z=-45, -36, 51) and left postcentral gyrus (MNI: x, y, z=-45, -33, 51). Compared with HC group, the DC of two patient groups increased in the right inferior temporal gyrus (MNI: acute x, y, z=63, -27, -21; chronic x, y, z=63, -21, -27); the DC of acute bereaved PTSD group decreased in the right temporal pole (MNI: x, y, z=45, 21, -15) and the right orbital inferior frontal gyrus (MNI: x, y, z=48, 24, -12), while the DC of chronic bereaved PTSD group decreased in the left inferior parietal angular gyrus (MNI: x, y, z=-45, -36, 51) and left postcentral gyrus (MNI: x, y, z=-45, -33, 51). Compared with chronic bereaved PTSD group, the DC of acute bereaved PTSD group increased in the left inferior parietal angular gyrus (MNI: x, y, z=-33, -39, 42) and left postcentral gyrus (MNI: x, y, z=-45, -33, 51), while decreased in the right temporal pole (MNI: x, y, z=51, 12, -9), right orbital inferior frontal gyrus (MNI: x, y, z=42, 21, -15) and bilateral medial superior frontal gyri (MNI: left x, y, z=0, 57, 15; right x, y, z=3, 57, 15). In chronic bereaved PTSD group, the DC of the left postcentral gyrus was negatively correlated with C1 (avoid trauma-related thoughts, feelings) score in CAPS ( r=-0.606, P=0.028). In acute bereaved PTSD group, the DC of the left medial superior frontal gyrus was negatively correlated with D4 (high vigilance) score ( r=-0.416, P=0.020). Conclusion:There exist functional abnormalities of multiple brain regions in acute and chronic bereaved parents with PTSD.The high arousal symptoms of the former may be related with the abnormalities of prefrontal-amygdala neural circuit, while the latter show higher avoidance which may be associated with the dysfunction of somatosensory brain regions such as postcentral gyrus.

Objective:To investigate the effect of coping style on the gray matter volume in patients with post-traumatic stress disorder (PTSD) who lost their only child, and the mediating role of gray matter volume in evaluating the influence of coping style in clinical symptoms of these parents.Methods:A total of 57 parents with PTSD (PTSD group) and 162 parents without PTSD (non-PTSD group) who lost their only child from September 2016 to March 2017 were enrolled from Jiangsu Province, China. Brain MRI data at resting state were collected. Voxel-based multiple regression analysis was performed to confirm the brain areas in which coping style main effect, diagnosis main effect and their interaction had significant influences in gray matter volumes. Correlations among gray matter volume of brain areas related to coping style, coping style scale scores, and clinician-administered PTSD scale (CAPS) scores were analyzed. Structural equation modeling was used to analyze the mediating role of gray matter volume in the influence of coping style in clinical symptoms of parents lost their only child.Results:(1) The coping style main effect did not significantly influence the gray matter volume in all subjects, and the diagnosis main effect had significant influence in gray matter volume in the right lingual gyrus; their interaction had significant influence in gray matter volume in the right peritalar fissure cortex and lingual gyrus. The positive coping style in the PTSD group had significant influence in the gray matter volumes of the right peritalar fissure cortex and lingual gyrus. (2) In the PTSD group, the scores of positive coping style were positively correlated with the gray matter volumes of the right talus fissure and the lingual gyrus ( P<0.05); the scores of positive coping style, and the gray matter volumes of the right talus fissure and the lingual gyrus were negatively correlated with scores of CAPS-C 5 and CAPS-C ( P<0.05). (3) In the PTSD group, positive coping style can positively predict the gray matter volumes of the right talus fissure and the lingual gyrus; the gray matter volumes of the right talus fissure and the lingual gyrus can negatively predict the avoidance-related symptoms. Conclusion:Positive coping style has influence in the gray matter volumes of the right talar fissure and lingual gyrus of PTSD patients lost their only child; and less positive coping style may affect the brain areas related to visual information processing, thus aggravating avoidance-related symptoms of PTSD patients.

【Objective】 To analyze the cause of single-ELISA reactive of four blood screening items in 18 blood stations in Henan, so as to provide the basis for improving the quality of blood screening. 【Methods】 The single-ELISA reactive rate of HBsAg, anti-HCV, HIV Ag/Ab and anti-TP of 18 blood station laboratories in Henan throughout 2019 was calculated, and the causes were analyzed according to different ELISA reagent combinations and gray area settings in each laboratory. 【Results】 The overall single-ELISA reactive rates of HBsAg, anti-HCV, HIV Ag/Ab and anti-TP were 1.740(2 154/1 237 789), 0.564‰(698/1 237 789), 1.421‰(1 759/1 237 789) and 1.561‰(1 932/1 237 789), respectively, showing significant differences by detection items (P <0.05). Person correlation analysis showed that the single-ELISA reactive rate was independent of the gray area settings.but dependent on laboratories and reagent combinations. The single-ELISA reactive rate of HBsAg, anti-HCV, HIV Ag/Ab and anti-TP in D laboratory was the highest and higher than that in other labs using the same reagent.The laboratories with high HBsAg single-ELISA reactive rate were mostly those using a combination of imported reagents and domestic reagents, including the top 6 laboratories. The laboratories with high anti-HCV single-ELISA reactive rate were mostly those using certain domestic reagents. No obvious rules was noticed by single-ELISA reactive for anti-HIV. Laboratories with high anti-TP single-ELISA reactive rate were mostly those using combination 4. 【Conclusion】 The HBsAg single-ELISA reactive rate was the highest in the four blood screening items of blood station laboratories in Henan. The single-ELISA reactive rate is related to the laboratory itself and the reagent manufacturer, suggesting that laboratory quality control should be strengthened and proper reagent combination should be selected to reduce the waste of blood.

【Objective】 To analyze the HIV-, HCV- and HBV- NAT yield rate in different areas of Henan province, so as to provide the basis for disease prevention and control as well as the establishment of a unified quality control standard for nucleic acid testing(NAT) in the Henan province. 【Methods】 The number and prevalence of NAT yielding samples with isolated infectious virus, namely HIV, HCV and HBV, in 18 blood stations in Henan province from 2017~2019, as well as the trends were analyzed. The NAT quality of each laboratory and each testing system was analyzed according to the ratio of reactive individual donation(ID) results to reactive minipools(MP). 【Results】 The HBV, HCV and HIV ID-NAT yield numbers in 3 501 251 blood donations were HBV 2 606(74/100 000), HCV 21 (0.63/100 000), and HIV 34(1.00/100 000). The HBV ID-NAT yield rate showed an upward trend in the whole province from 2017 to 2019, while the prevalence of HIV and HCV ID-NAT yield didn′t differ significantly during three years. 5 kinds of NAT detection systems were applied in 18 blood centers. among which Ⅰ, Ⅱ, Ⅳ and Ⅴ were triplex detection systems. 2661 ID-reactive samples were implicated in 5 595 MP-reactive samples, with a resolution rate of 47.56%. The resolution rate of triplex NAT system Ⅰ, Ⅱ, Ⅳ and Ⅳ was 39.63%~47.95%, 40.43%~54.36%, 51.61% and 70.00%~45.45%, respectively. An upward trend in triplex NAT resolution rate was observed in 8 laboratories, i. e.B, D, E, F, I, K, L and Q, and an descending trend in A and C. The NAT system Ⅲ, a ID-NAT system, was used only by laboratory C, presenting a NAT-yield rate of 0.19% (282/145 474) and resolution rate of 46.45% (131/282). 【Conclusion】 The majority of NAT-yield of one infectious virus in Henan province is HBV, presenting annual increasing trend. The quality management of NAT laboratories should be strengthened as the divergence was seen in the performance of different NAT laboratories.
