Objective To investigate the correlation between self-injurious and suicidal behavior in adolescents with depressive disorder and their non-enzymatic antioxidants and thyroid hormones.Methods A total of 93 adolescent patients with depressive disorder who were hospitalized at the Qingdao Mental Health Center from August 2023 to May 2024 were selected as the research subjects.The patients were divided into three groups:depression group(n=33),self-injurious behavior group(n=30)and a suicidal behavior.Plasma levels of non-enzymatic antioxidants and thyroid hormones were measured at admission and after 8 weeks of treatment,and their clinical symptoms were assessed by the Hamilton depression scale(HAMD)and the Hamilton anxiety scale(HAMA).Differences in plasma non-enzymatic antioxidants and thyroid function levels and scale scores were compared among three groups.Results Compared with depression group,baseline UA levels were lower in self-injurious and suicidal behavior groups.After 8 weeks of treatment,FT3 levels were higher in self-injurious group than in the suicidal behavior group,and both HAMD and HAMA scores decreased in all patients.After correction,HAMA scores were higher in suicidal behavior group than in depression group(P=0.047).Compared to baseline levels,TSH levels increased,and HAMD and HAMA scores decreased in all groups after treatment(P＜0.001).In suicidal behavior group,TBIL and FT3 levels decreased,and UA levels increased after treatment,while in depression group,FT4 levels decreased after treatment.Conclusion Non-enzymatic antioxidants may serve as potential biological markers for adolescents with depressive disorder who exhibit self-injurious and suicidal behavior.

Pancreaticoduodenectomy (PD) is a primary surgical approach for treating mali-gnant tumors of the pancreatic head and the periampullary region. With the advance in medical technology in recent years, the long-term survival rate of patients undergoing PD has significantly improved, and the incidence of early perioperative complications has markedly decreased. However, current researches predominantly focuse on early postoperative complications, while, limited studies addressing long-term complications. Long-term complications after PD have a significant impact on patients′ quality of life and long-term survival. This authors systematically summarize the common long-term complications following PD, and explore their mechanisms, clinical manifestations, dia-gnostic methods, and treatment strategies, aiming to provide a reference for clinical practice.

Objective To evaluates the impact of early application of neuromuscular electrical stimulation(NMES)on muscle strength,clinical outcomes,and long-term quality of life improvements in patients with severe acute pancreatitis(SAP)complicated with acute respiratory distress syndrome(ARDS).Methods A total of 75 patients diagnosed with SAP and ARDS admitted in Department of Critical Care Medicine of our hospital from September 2022 to August 2023 were recruited and then randomly divided into NMES group(n=37)and control group(n=38).After 16 patients were excluded,including 8 died during treatment,3 discharged and 5 received palliative care,there were finally 29 patients in the NMES group and 30 in the control group.Within 48 h after ICU admission,the NMES group received NMES 1 h per day,for 7 d in addition to standard rehabilitation intervention.While,the control group were given conventional interventions for rehabilitation.Assessments at baseline and post-treatment included the incidence of ICU-acquired weakness(ICU-AW),Medical Research Council(MRC)score,duration of mechanical ventilation,lengths of ICU and total hospital stays,and activity,thickness and thickening fraction of the diaphragm.Mortality rates and Barthel index(BI)for self-care ability in 1,3 and 6 months after discharge were recorded for follow-up assessments.Results The NMES group had significantly lower incidence of ICU-AW(P＜0.05),higher upper and lower limb MRC scores and overall MRC score at ICU discharge(P＜0.05),shorter durations of mechanical ventilation,ICU stay,and total hospital stay when compared with the control group(P＜0.05).There was no statistical difference in the BI at 1 month post-discharge between the 2 groups,but the indexes at 3 and 6 months were notably higher in the NMES group than the control group(P＜0.05).No obvious differences were observed between the 2 groups in terms of diaphragm activity,thickness,or thickening scores at enrollment,ICU discharge,or hospital discharge,nor in mortality rates at 1,3,and 6 months after discharge.Conclusion Combined NMES and early rehabilitation therapy can improve muscle strength and reduce length of hospital stay in SAP patients complicated with ARDS,and may enhance long-term quality of life.However,it does not significantly affect diaphragm function or mortality rates.

Pancreatic cancer is one of the most common tumors in digestive system, which is characterized by insidious clinical symptoms, strong invasion, easy metastasis and high mortality. In recent years, immunotherapy is a new direction to the treatment of solid tumors, but its applica-tion in pancreatic cancer is limited by tumor microenvironment of pancreatic cancer. The authors systematically analyze the tumor microenvironment of pancreatic cancer, summarize the clinical researches related to pancreatic cancer immunotherapy, and discuss the prospect of pancreatic cancer immunotherapy.

【Objective】 To reveal possible mechanisms of miRNA in diabetic hepatopathy through bioinformatics method. 【Methods】 Subset data of miRNA and their matched mRNAs in the liver of STZ-induced diabetic mice and the normal liver tissues of congenial mice by detecting on microarrays were collected from GEO database； information from the database and bioinformatics analysis were applied to mine a batch of miRNAs in diabetic hepatopathy and targeted mRNAs regulated. Then qRT-PCR was used to verify the expressions of miRNAs in diabetic liver from 20 STZ-treated Kunming mice and 10 normal homologous mice. 【Results】 Via detection and analysis， miRNAs differentially expressed （including 96 up-regulated and 77 down-regulated） were significantly obtained. Groups of miRNAs and their effectors （mRNAs） that may be related to the pathological process of diabetic liver disease in mice were screened by GO and KEGG enrichment analyses， combined with relevant protein annotations in the databases and references. The expressions of miR-200a-3p， miR-200b-3p and miR-222-3p in the mice’s liver tissue detected by qRT-PCR were significantly down-regulated. In addition， the expressions of related effector genes CERS6， MYBL1， SCD2， SLCO1A4 and PLK2 were up-regulated， while the expressions of ACSS2， BCL6 and SLC10A2 were down-regulated. 【Conclusion】 The variation trend of those candidate miRNAs in mouse diabetic liver compared with that in control livers was consistent with that of the previous studies and prediction， which revealed their potential molecular regulation in this disease process.

Objective:To investigate the safety and feasibility of modified pararectus abdominis approach in the anterior plate fixation of sacral fractures.Methods:In 5 fresh adult cadavers (3 males and 2 females), gross anatomy was performed on one pelvic side using a modified pararectus abdominis approach to clarify the anatomical structures around the approach. On the other side of the pelvis, the anterior structures of the sacrum were exposed in simulated anterior plate fixation of sacral fracture via the modified pararectus abdominis approach. The exposed anatomic range of the approach, and the locations and courses of lumbosacral trunk nerve and iliac vessels were observed and recorded.Results:(1) The modified pararectus abdominis approach exposed the whole S1 vertebral body from the sacroiliac joint to the medial side, the L5 vertebral body cephalally, the S1 foramina in the true pelvis, and the same structures laterally as a traditional pararectus abdominis approach did. (2) Via the modified pararectus abdominis approach, exploration and decompression of the lumbosacral plexus (from L4 to S1) (including S1 foraminoplasty) were performed under direct vision to decompress the nerve entrapment from anterior compressed fracture fragments and hyperplastic callus. (3) There was a safe surgical area in anterior L5 and S1 where a plate could be safely fixed to the S1 vertebral body. (4) Since the maximum vertical distance from the lumbosacral trunk nerve lifted above the periost to the sacral ala was 1.4 cm (range, from 1.2 to 1.5 cm), a plate could be safely placed from the subperiosteum to the S1 vertebral body to fix the fracture.Conclusions:The modified pararectus abdominis approach is safe and feasible for exploration and decompression of lumbosacral nerves in the anterior sacral region (from L4 to S1) because it has significant advantages in vision and operation. It also broadens the range of anterior sacral plate fixation because a sacral fracture displacement can be reduced under direct vision and a plate can be fixated to the S1 vertebral body along the alae sacralis and across the sacroiliac joint to the iliac bone.
