Fungi are widely present in the human environment and generally non-pathogenic.However,they may invade tissues and cause disease when host immunity is compromised or conditions conducive to fungal proliferation arise.A case of a 70-year-old woman with acute gastrointestinal perforation and secondary abdominal infection,admitted to the department of intensive care medicine(ICU)of the Affiliated Hospital of Qingdao University on August 17,2021 was enrolled.Following emergency exploratory laparotomy with gastric perforation repair,partial small bowel resection,peritoneal lavage drainage,and jejunal feeding jejunostomy,the patient received imipenem and cilastatin sodium antimicrobial therapy.Despite these interventions,clinical deterioration ensued with septic shock and multiple organ dysfunction syndrome.Prompt initiation of antifungal therapy alongside existing anti-infective treatment,anti-shock management,continuous renal replacement therapy(CRRT),and invasive mechanical ventilation led to rapid clinical improvement.Notably,blood cultures obtained at admission revealed Candida albicans after 5 days in ICU,while pathological examination of gastric pyloric perforation margins(8 days post-admission)demonstrated abundant Candida and small bowel ulcer sections showed extensive Mucor infiltration.This case highlights critical lessons in ICU management:Invasive fungal infection should be strongly suspected when gastrointestinal perforation patients deteriorate despite adequate surgical intervention and empirical antibacterial therapy;Timely fungal diagnostic workup should be initiated,utilizing validated fungal infection risk assessment tools to guide rapid diagnosis;Early empirical antifungal therapy proves crucial for improving outcomes in such critical scenarios.

Objective:To explore the mediating effect of sleep quality on the relationship between serum vitamin D3 level and depressive symptoms in community-dwelling elderly people with mild cognitive impairment(MCI).Methods:A total of 480 elderly people with MCI meeting inclusion criteria in a community health service center from Jan 2023 to Dec 2023 were selected as the research objects.The general information questionnaire,mini-mental state examination(MMSE),activity of daily living scale(ADL),Center for Epidemiological Studies Depression Scale(CES-D)and Pittsburgh sleep quality index(PSQI)were used to investigate the subjects.Serum vitamin D3 level was detected within 1 week.Spearson correlation analysis was used to explore the correlation between sleep quality,serum vitamin D3 level and depressive symptoms.The mediating effect model was tested by Model 4 in the Process plug-in.Results:Among the 480 MCI elderly,the average score of depression was(12.28±4.75),the average serum vitamin D3 level was(25.81±7.09)ng/ml,and the average score of sleep quality was(7.17±2.71).Depression severity was positively correlated with sleep quality score(r=0.294,P＜0.01),and negatively correlated with serum vitamin D3 level(r=-0.237,P＜0.01).Serum vitamin D3 level was negatively correlated with sleep quality score(r=-0.225,P＜0.01).Bootstrap analysis showed that the mediating effect of sleep quality between serum vitamin D3 level and depression level was-0.064(95%CI:-0.115--0.023),accounting for 26.57%of the total effect.Conclusion:Sleep quality partially mediates the relationship between serum vitamin D3 level and depressive symptoms in the elderly with MCI in the community.

【Objective】 To study the effect and mechanism of lncRNA XIST targeting miR-150 on LPS-induced apoptosis and secretion of inflammatory factors in MLE-12 cells. 【Methods】 Mouse lung epithelial MLE-12 cells were divided into control, LPS (LPS treatment), sh-NC+LPS (shRNA control transfection, LPS treatment), and sh-XIST+LPS (XIST shRNA transfection, LPS treatment) groups. We used qRT-PCR method to analyze and detect XIST expression level, Annexin V-FITC/PI double staining method to detect cell apoptosis, Western blotting method to analyze and detect the protein expressions of Bax and Bcl-2 in cells, TBA method to detect MDA content, Xanthine oxidation method to detect SOD activity, DCFH-DA method to detect ROS level, and ELISA method to analyze the levels of IL-1β and TNF-α in the culture supernatant. We used the bioinformatics software Starbase to analyze the possible target genes of XIST (miR-150), and then the luciferase reporter system to identify the target relationship between the two. In MLE-12 cells, XIST shRNA and miR-150 inhibitor were co-transfected, and then treated with LPS. We also measured apoptosis, oxidative damage indicators, and inflammatory factor secretion changes. 【Results】 Compared with control group, XIST level in MLE-12 cells of LPS group increased, apoptosis rate and Bax protein expression level increased, Bcl-2 protein expression level decreased, ROS and MDA level increased, SOD level decreased, and the secretion of IL-1β and TNF-α increased. Compared with the sh-NC+LPS group, the sh-XIST+LPSMLE-12 group had decreased XIST level, decreased apoptosis rate and Bax protein expression level, and increased Bcl-2 protein expression level, decreased ROS and MDA levels, increased SOD levels, and decreased IL-1β and TNF-α secreted by cells. Down-regulating XIST targeting promoted miR-150 expression. miR-150 inhibitor could reverse the effects of XIST shRNA on LPS-induced MLE-12 cell apoptosis, oxidative damage indicators, and inflammatory factor secretion. 【Conclusion】 Down-regulation of lncRNA XIST targeting miR-150 inhibits LPS-induced apoptosis and secretion of inflammatory factors in mouse lung epithelial MLE-12 cells.

Objective:To examine the surgical approach, practical cognition as well as clinical effect of the orthotopic resection for laparoscopic pancreatoduodenectomy(OLPD).Methods:From March 2019 to December 2019, 32 cases were treated with laparoscopic pancreatoduodenectomy (LPD) in a novel approach without mobilization of pancreatoduodenum in Pancreas Center of the Second Affiliated Hospital of Guangzhou University of Chinese Medicine.There were 16 male patients and 16 female patients.The mean age was (64.8±9.5) years old.Body mass index was 14.9 to 31.0 kg/m 2.All patients were diagnosed as ampullary or pancreatic head tumors and were not unresectable cases.In the surgical strategy, Kocher′s dissociation, turning and pulling of the pancreaticoduodenal region, was not performed first.Anatomy in situ, separation of vessels which enter and exit from pancreas, separation of lymphatics and isolation of tumors were carried out in priority through the combined middle and left posterior approaches.Finally, the pancreatic head and duodenum region was mobilized and the entire resection of pancreas in situ was carried out.Digestive tract reconstruction was performed through Child method. Results:Postoperative pathology showed that 27 cases were pancreatic or ampullary malignant tumors and five cases were benign tumors among 32 patients.The operative time was (357.3±64.3) minutes.The diameter of pancreatic ducts was (3.0±1.0) mm. The pancreas of 20 cases (62.5%) were soft. Five patients suffered from pancreatic fistula (Grade B) and one patient suffered from intra-abdominal hemorrhage postoperatively.No other complications like pancreatic fistula (Grade C) or biliary fistula delayed gastric emptying or mortality were encountered.The postoperative hospital day was (13.7±3.6) days.Conclusions:Combining the multi-angle of the laparoscopic approaches and excising the pancreaticoduodenal specimen in situ, OLPD is a kind of surgical method which can realize the concept of no touch tumor surgery.Patients who undergo the OLPD can receive better treatments and results.

Pancreaticoduodenectomy is one of the most difficult abdominal operations, and the difficulty in resection and complicated digestive tract reconstruction have brought great challenges for surgeons. At present, laparoscopic pancreaticoduodenectomy has been widely used in clinical practice, and compared with traditional 2D laparoscopy, 3D laparoscopy has the features of high magnification, high definition, and three-dimensional vision, which enables surgeons to see more clearly and operate more accurately, and thus it has great potential to be widely used in pancreaticoduodenectomy.

Objective To investigate the treatment effects of Kansui root on severe acute pancreatitis (SAP) with abdominal compartment syndrome (ACS).Methods 16 cases of SAP were randomly divided into kansui root treatment group and control group according to random number table.Patients in control group received routine treatment including fasting, anti-shock, antibiotics and nutritional support.And the patients in kansui root group received routine treatment plus kansui root therapy.The clinical and laboratory parameters were determined and compared between the two groups.Results The relieving time of abdominal pain, bowel sound, the recovery time of hyperamylasemia, body temperature and leukocyte count in treatment group was (7.6±2.3)d, (6.1 ±3.1)d, (5.9±3.3)d, (5.2 ±3.2) d, (6.3 ±2.1)d, which were significantly shorter than those in control group [ ( 11.7 ± 2.1 ) d, ( 11.2 ± 2.3d, ( 10.2 ± 2.7) d, (9.2 ± 3.5 ) d, ( 11.1 ±3.3)d, P＜0.01 ) ].At the 3rd, 4th and 5th day, the intra-abdominal pressure in treatment group were also significantly lower than those in control group[ ( 19.8 ±3.1 )cmH2O vs(23.7 ±2.9) cmH2O, ( 12.3 ±2.7) cmH2O vs (21.3±1.5)cmH2O,(8.2±3.1)cmH2O vs (17.3 ±2.3)cmH2O,P＜0.05].Conclusions Severe acute pancreatitis has close relationship with Jiexiong syndrome in traditional chinese medicine.Kansui root is an effective therapy for alleviating high intra-abdominal pressure.

Objective To investigate the expression of pro-irtilammatory mediator in peripheral blood of patients with severe sepsis treated by different therapeutic dose of high-volume hemofiltration (HVHF). Methods According to the standard of severe sepsis, 83 cases were randomly divided into three groups, A group [60 ml/(kg·h)], S group[80 ml/(kg·h)], C group[100 ml/(kg·h)], respectively. The levels of TNF-α, IL-1, IL-8 in plasma of patients were measured by enzyme-linked immunosorbent assay (ELISA) before treatment and at 2, 4, 6, 8, 10 h after treatment, and the grades of APACHEⅢ were evaluated at every time-point simultaneously. Results The grades of APACHEⅢ were lower after treatment than those before treatment (P<0.05), but the decreases between every group had no significant deviation (P>0.05). The levels of TNF-Ⅲ, IL-1, IL-8 in plasma of patients were all decreased gradually after treatment. Compared with those before treatment, the levels of TNF-α,IL-1 and IL-8 at 2, 4 and 6 h after HVHF were obviously decreased (P<0.05). The levels of TNF-α, IL-1 and IL-8 were lightly increases at 4 and 6 h after HVHF, but they were lower that those before treatment (P<0.05). At every time-point, the levels of TNF-α, IL-1, IL-8 trended to decrease following the increase, of displacement liquid volume, the mean levels of pro-inflammatory mediator in C group were markedly reduced compared with the levels in A group (P<0.05). Conclusion HVHF can decrease the levels of pro-inflammatory mediator in peripheral blood of patients with severe sepsis and the grades of APACHEⅢ, the more the therapeutic dose of HVHF, the lower the levels of pro-inflammatory mediator.
