Objective To investigate the effect of a three-tier delirium care management process in patients with acute stroke in neurology intensive care unit(NICU).Methods A total of 50 patients with acute stroke admitted to the NICU of the Fourth Hospital of Changsha from May to September 2021 were assigned to the control group.The patients in the control group received routine NICU nursing care to prevent delirium.Another 50 patients with acute stroke admitted to the NICU from December 2021 to April 2022 were assigned to the trial group.They were managed with the three-tier delirium nursing management process on top of the routine NICU nursing care for the control group.The incidence of ICU delirium(DICU),duration of DICU,length of stay in NICU and the incidence of delirium-related adverse events were compared between the two groups.The degree of delirium and cognitive function before and after the intervention were compared between the two groups as well.Results The trial group had significantly shorter duration of DICU and NICU stay(both P<0.05)and lower incidence rate of delirium-related adverse events(P<0.05)compared to the control group.After the intervention,the trial group showed significantly lower scores on the intensive care delirium screening checklist(ICDSC)and significantly higher scores of cognitive function compared to those of the control group(both P<0.05).Conclusion The three-tier delirium nursing management process can lower the occurrence of delirium in NICU patients with acute stroke,shorten the NICU stay,reduce the safety risk in nursing,and improve the cognitive function.

Glyceryl phenylbutyrate(GPB)serves as a long-term management medication for Ornithine transcarbamylase deficiency(OTCD),effectively controlling hyperammonemia,but there is a lack of experience in using this medicine in China.This article retrospectively analyzes the case of a child diagnosed with OTCD at Shanghai Children's Medical Center,Shanghai Jiao Tong University School of Medicine,including a review of related literature.After diagnosis,the patient was treated with GPB,followed by efficacy follow-up and pharmacological monitoring.The 6-year and 6-month-old male patient exhibited poor speech development,disobedience,temper tantrums,and aggressive behavior.Blood ammonia levels peaked at 327 μmol/L;urine organic acid analysis indicated elevated uracil levels;cranial MRI showed extensive abnormal signals in both cerebral hemispheres.Genetic testing revealed de novo mutation in the OTC gene(c.241T＞C,p.S81P).Blood ammonia levels were approximately 43,80,and 56 μmol/L at 1,2,and 3 months after starting GPB treatment,respectively.During treatment,blood ammonia was well-controlled without drug-related adverse effects.The patient showed improvement in developmental delays,obedience,temperament,and absence of aggressive behavior.

Objective To establish an ideal modeling method for diarrhea predominant irritable bowel syndrome(IBS-D)with anxiely and depression in rats,and to provide a basis for the clinical study of IBS-D.Methods 60 rats were used in this study.(1)At first,20 rats were randomly divided into blank,3%acetic acid enema,4%acetic acid enema,and 5%acetic acid enema groups.After the modeling and observation period,the diarrhea status and the degree of colon injury caused by different modeling concentrations were observed by diarrhea related index and colon histopathology.(2)After the optimal modeling concentration was assessed,40 rats were randomly divided into control(a),acetic acid enema(b),acetic acid+binding(c),and acetic acid+binding+tail clip(d)groups and correspondingly treated for 8 days.After the treatments,the general condition,diarrhea-related index,open field test(OFT)score,and colonic histopathology of rats were evaluated.Results(1)Compared with the blank group,the fecal trait score of 4%acetic acid enema group was increased on days 1 to 3 after intervention(P＜0.001),and gradually decreased on days 4 to 7 after intervention.After 1 week,there was no significant difference between the fecal trait score and that of the blank group(P＞0.05).Body weight was lower(P＜0.01),fecal water content was higher(P＜0.001).Compared with blank group,body weight of the 5%acetic acid enema group was decreased(P＜0.001),the fecal trait score and diarrhea index were increased(P＜0.01).No significant difference was found between 3%acetic acid enema and blank groups.The pathological colon tissue showed that,compared with the blank group,the mucosal structure of the 4%acetic acid enema group was complete with a small amount of inflammatory cell infiltration,and the pathological tissue score showed no significant difference(P＞0.05),whereas the 5%acetic acid enema had a medium to large amount of inflammatory cell infiltration,and the pathological tissue score was increased(P＜0.01).(2)Compared with group a,group b had lower body weight(P＜0.001),and higher fecal trait score,fecal water content and diarrhea index(P＜0.01).Compared with a and b groups,the body weight of c and d groups was lower(P＜0.001),the fecal traits score,fecal water content,and diarrhea index were increased(P＜0.01),and the colon running time was decreased(P＜0.01).Compared with group c,Fecal water content in group D was higher(P＜0.001).In the OFT score,compared with a and b groups,the OFT distance,standing times,and upright times in c and d groups were lower(P＜0.05).Compared with c,the OFT distance,standing times,and upright times in d group were lower(P＜0.05).The pathological tissue of colon showed that the mucosal structure of the four groups was complete,and there were different degrees of inflammatory cell infiltration.The pathological tissue scores of groups c and d were higher than those of groups a and b(P＜0.05).Conclusions The 4%acetic acid concentration is appropriate for IBS-D modeling.After superposition and binding,the IBS-D diarrhea and internal hypersensitivity characteristic state can be better simulated.After superposition of a tail clip,the IBS-D model of liver stagnation and spleen deficiency can be established successfully.

OBJECTIVES: To explore the effect of acupuncture and moxibustion on intestinal flora in the rats with diarrhea-predominant irritable bowel syndrome (IBS-D) based on 16S rDNA technique. METHODS: Ten rats were randomized from 58 SPF-grade male SD rats to be the blank group. The remained 48 rats were prepared to be IBS-D models by the modified method of acetic acid enema combined with binding tail-clip stress. Forty successfully-modeled rats were randomly divided into a model group, an acupuncture group, a moxibustion group and a western medication group, with 10 rats in each one. In the acupuncture group, the needle was inserted at bilateral "Zusanli" (ST 36) and remained for 15 min in each rat. In the moxibustion group, the suspending moxibustion was delivered at bilateral "Zusanli" (ST 36) for 15 min. The rats in the western medication group were given pinaverium bromide suspension (10 mL/kg) by intragastric administration. The above interventions were performed once daily for consecutive 14 days. The body mass and the score of fecal trait were compared before and after modeling, as well as after intervention in each group. Fecal water content, diarrhea index and colon transit time (CTT) were measured after modeling and intervention in the rats of each group separately. After intervention, the colonic morphology of rats in each group was observed, and using 16S rDNA technique, the intestinal flora was detected. RESULTS: After modeling, compared with the blank group, the body mass and CTT were reduced (P<0.01); fecal trait scores, fecal water contents and diarrhea index increased (P<0.01) in the other 4 groups. After intervention, the body mass and CTT of the rats decreased (P<0.01), and fecal trait score, fecal water content and diarrhea index increased (P<0.01) in the model group compared with those in the blank group. In the acupuncture group, the moxibustion group and the western medication group, when compared with the model group, the body mass and CTT were elevated (P<0.01), while fecal trait scores, fecal water contents and diarrhea index declined (P<0.01). Compared with the western medication group, fecal water content decreased in the acupuncture group and the moxibustion group (P<0.05), while CTT increased in the acupuncture group (P<0.01), the body mass increased and fecal trait score was dropped in the moxibustion group (P<0.05). The colonic mucosa structure was clear and complete, and there was no obvious inflammatory cell infiltration in the blank group. The mild interstitial edema of intestinal mucosa was presented with the infiltration of few inflammatory cells in the model group. There was the infiltration of few inflammatory cells in the mucosa of the acupuncture group, the moxibustion group and the western medication group. Compared with the blank group, the indexes of Richness, Chao1, ACE and Shannon decreased in the model group (P<0.05). Indexes of Richness, Chao1 and ACE increased in the acupuncture group and the moxibustion group (P<0.05), and the Richness index in the western medication group increased (P<0.05) when compared with those in the model group. The relative abundance of Bacteroidetes, Proteobacteria and Prevotella increased (P<0.05), and that of Firmicutes and Muribaculaceae decreased (P<0.05) in the model group compared with those in the blank group. When compared with the model group, the relative abundance of Bacteroidetes, Proteobacteria and Prevotella was reduced (P<0.05), while that of Firmicutes and Muribaculaceae increased (P<0.05) in the acupuncture group, the moxibustion group and the western medication group; and that of Actinobacteria and Bifidobacterium increased in the acupuncture group and the moxibustion group (P<0.05). Compared with the blank group, the relative abundance of lipopolysaccharide (LPS) biosynthesis was elevated (P<0.05), and that of folate biosynthesis, lipoic acid metabolism, zeatin biosynthesis, ubiquinone and other terpenoid quinone biosynthesis decreased (P<0.05) in the model group. The relative abundance of LPS biosynthesis was dropped (P<0.05), and that of folate biosynthesis, lipoic acid metabolism, zeatin biosynthesis, ubiquinone and other terpenoid quinone biosynthesis increased (P<0.05) in the acupuncture group, the moxibustion group and the western medication group compared with those of the model group. CONCLUSIONS Either acupuncture or moxibustion can relieve the symptoms of IBS-D and protect intestinal mucosa, which may be associated with regulating the structure of intestinal flora and promoting nutrient metabolism and biosynthesis.

OBJECTIVE: To compare the short-term clinical efficacy of SuperCap approach and direct anterior approach in total hip arthroplasty. METHODS: Clinical data of 70 patients who underwent minimally invasive SuperCap approach and DAA THA in January 2016 to June 2017 were retrospective analyzed. These patients were divided into two groups:SuperCap approach group(SuperCap group) and direct anterior approach group(DAA group). There were 15 males and 15 females in SuperCap group, aged from 45 to 71 years old, and the follow-up time ranged from 24 to 30 months. There were 24 males and 16 females in Group B, aged from 51 to 76 years and the follow-up time ranged from 24 to 36 months. Hemoglobin level of the 3rd day after operation, transfusion rate, acetabular abduction angle, anteversion angle and creatine kinase level of the 3rd day after operation, Harris score of 3 months and the last time, VAS score of 1 week and the last time were recorded and compared. Complications were recorded at the final follow-up. RESULTS: All patients were followed up, the follow-up time of SuperCap group ranged from 24 to 30 months, that of DAA group ranged from 24 to 36 months. No significant differences were found in hemoglobin level on the 3rd day after operation, transfusion rate, Harris score or VAS score between two group (P>0.05). There was no significant difference in Harris score between 3 months after operation and the final follow-up in both groups (P>0.05). There were no significant difference in VAS scores of 6 weeks after operation and on the final follow-up neither(P>0.05). The level of creatine kinase in SuperCap group was significant lower than that in DAA group(P<0.05). Until the final follow-up, there was no significant difference in the incidence of complications between the two groups(P>0.05). CONCLUSION The clinical effect of minimally invasive SuperCap approach after total hip arthroplasty is comparable to that of DAA approach with less soft tissue injury. Patients can recover rapidly after operation and it is a safe and effective surgical approach for surgeons with short learning curve.

Aim To explore the effects of putative receptor protein related to ATI (APJ) homodimer on the behaviors-the proliferation, migration and tube formation of human umbilical vein endothelial cells (HU-VECs). Methods HUVECs at logarithmic growth stage were randomly divided into PBS, Apelin-13 + TM1 (APJ monomer group) and Apelin-13 + PBS group (APJ homodimer group). Western blot and Matrix-Assisted Laser Desorption/Ionization Time of Fligh Mass Spectrometry (MALDI-TOF MS) were used to detect the expression of APJ and APJ homodimer in HUVECs, respectively. Real-Time Cell Analyzers (RT-CA) was used to detect the concentration of the maximum effect of Apelin-13. Cell viability was detected by CCK-8. The cell migration ability was detected by scratch test, and the number of tubes formed on matri-gel that made artificial basement membrane was counted. Results Western blot and MALDI-TOF MS showed that APJ and APJ homodimer were expressed in HUVECs. The EC50 of Apelin-13 was 2.26 x 10

Objective: To investigate the clinicopathological and molecular characteristics of hepatic fibrinogen storage disease (FSD) in children. Methods: The clinical, histopathologic, immunophenotypic, ultrastructural and gene sequencing data of 4 FSD cases were collected from September 2019 to January 2021 in the Children's Hospital of Fudan University, Shanghai, China. Retrospective analysis and literature review were conducted. Results: There were 4 cases of FSD, 3 males and 1 female, aged 3 years and 3 months to 6 years (median age, 3 years and 4 months). The clinical manifestations were abnormal liver function and abnormal blood coagulation function, for which 2 cases had family genetic history. Liver biopsies revealed that, besides liver steatosis, fibrosis and inflammation, there were single or multiple eosinophilic inclusion bodies of various sizes and surrounding transparent pale halo in hepatocytes. Immunohistochemistry showed that the inclusion bodies were positive for anti-fibrinogen. Under the electron microscope, they corresponded to the dilated cisternae of the rough endoplasmic reticulum, which were occupied by compactly packed tubular structures and arranged into a fingerprint-like pattern with curved bundles. Gene sequencing revealed that the 2 cases of FGG mutation were located in exon 8 c.1106A>G (p.His369Arg) and c.905T>C (p.Leu302Pro), and 1 case was located in exon 9 c.1201C>T (p.Arg401Trp). No pathogenic variant was detected in the other case. Conclusions: FSD is a rare genetic metabolic disease and clinically manifests as abnormal liver function with hypofibrinogenemia. In the background of liver steatosis, fibrosis and inflammation, there are eosinophilic inclusions with pale halo in the hepatocytic cytoplasm, which can be identified by anti-fibrinogen immunohistochemical staining. The fingerprint-like structures under electron microscope are helpful for the diagnosis, while FGG sequencing detects the pathogenic mutation of exon 8 or 9 that can clearly explain the phenotype. However, the diagnosis of FSD cannot be completely ruled out if the relevant mutations are not detected.

Accurately predicting the risk of mediastinal lymph node metastasis before surgery is of great significance for tumor staging, treatment plan decision, and prognosis evaluation in patients with non-small cell lung cancer(NSCLC). Traditional imaging methods such as CT, MRI and PET/CT are currently the most commonly used clinical methods in clinical evaluation of lymph node status. However, it is subjective to judge lymph node metastasis only by the change of image morphological characteristics, and inflammatory lymphadenopathy will also lead to a high false positive rate. The clinicopathological characteristics obtained by analyzing the clinical data of patients with NSCLC can improve the accuracy of lymph node metastasis prediction to a certain extent. The clinical prediction model based on medical images combined with the clinical characteristics of patients can provide more intuitive and rational information for doctors and patients, but the performance and applicability of the model will inevitably decrease due to changes in disease risk factors and treatment measures. In recent years, with the significant improvement of image analysis technology and computing ability, radiomics models based on medical images can deeply dig into the data in radiological images for quantitative analysis, providing new ideas for predicting mediastinal lymph node metastasis in NSCLC patients, which has attracted extensive attention at home and abroad. This article reviews the progress and makes prospects of the above methods in the prediction of mediastinal lymph node metastasis in NSCLC.

Lung cancer is the most common cancer and the leading cause of cancer-related death in China. Early screening of lung cancer proves to be effective in improving its prognosis. The National Comprehensive Cancer Network (NCCN) has updated and released version 2, 2022 NCCN clinical practice guidelines for lung cancer screening in July, 2022. Based on high-quality clinical evidence and the latest research progress, the guidelines have developed and updated criteria for lung cancer screening which have been widely recognized by clinicians around the world. Compared with Chinese lung cancer screening guidelines, this article will interpret the updated content of the brand new 2022 NCCN screening guidelines, providing some reference for the current lung cancer screening practice in our country.

This paper established the identification technology of the main root origin of three-year-old spring Panax notoginseng aiming at providing theoretical basis for the protection and traceability of geographical indication products of P. notoginseng. Forty-four samples of three-year-old spring P. notoginseng from Guangxi Baise, Yunnan Wenshan, Yunnan new cultivating regions. The stable isotopic ratios of carbon, nitrogen, hydrogen and oxygen were determined by elemental analysis and stable isotope mass spectrometer. Combined with Duncan multiple comparative analysis, fisher discriminant analysis and sequential discriminant analysis, a origin discriminant model for the main root of three-year-old spring P. notoginseng was established for 3 production areas of P. notoginseng. The geographical climate and environment of three production areas of P. notoginseng are obviously different. From Guangxi Baise-Yunnan Wenshan-Yunnan new cultivating regions, the longitude, average annual temperature and annual precipitation gradually decrease, and the elevation and latitude are increasing. The results of multiple comparative analysis showed that there were significant or very signi-ficant differences in the δ~(13)C,δ~(15)N,δ~2H,δ~(18)O of the main roots of P. notoginseng in three regions. The results of fisher's discriminant analysis and sequential discriminant analysis showed that the correct discriminant rates of the main roots of P. notoginseng for three regions were 80.05%,76.47% and 90.91%, respectively, based on four stable isotope ratios, with an average of 84.09%. Using stable isotope fingerprint and chemometrics method, we can distinguish the origin of the main raw materials and products of P. notoginseng.
