Objective     To explore the efficacy of prone positioning ventilation in patients with acute respiratory distress syndrome (ARDS) after acute Stanford type A aortic dissection (STAAD) surgery. Methods     From November 2019 to September 2021, patients with ARDS who was placed prone position after STAAD surgery in the Xiamen Cardiovascular Hospital of Xiamen University were collected. Data such as the changes of blood gas, respiratory mechanics and hemodynamic indexes before and after prone positioning, complications and prognosis were collected for statistical analysis. Results    A total of 264 STAAD patients had surgical treatment, of whom 40 patients with postoperative ARDS were placed prone position. There were 37 males and 3 females with an average age of 49.88±11.46 years. The oxygen partial pressure, oxygenation index and peripheral blood oxygen saturation 4 hours and 12 hours after the prone positioning, and 2 hours and 6 hours after the end of the prone positioning were significantly improved compared with those before prone positioning ventilation (P<0.05). The oxygenation index 2 hours after the end of prone positioning which was less than 131.42 mm Hg, indicated that the patient might need ventilation two or more times of prone position. Conclusion     Prone position ventilation for patients with moderate to severe ARDS after STAAD surgery is a safe and effective way to improve the oxygenation.

Objective To explore the clinical value of endoscopic ultrasonography(EUS)combined with serum serine protease inhibitor Kazal 1(SPINK1)and secretory phosphoprotein 1(SPP1)in early diagnosis of esophageal cancer.Methods 276 patients from June 2021 to May 2023 were selected as the study objects.92 cases of esophageal cancer diagnosed by operation and pathology were esophageal cancer group,another 89 patients diagnosed as benign esophageal lesions through tissue biopsy were selected as the benign lesion group,and 95 healthy individuals who underwent physical examinations were collected as the healthy control group,general information such as age and gender of subjects in three groups were collected and organized;using pathological results as the gold standard,the accuracy of EUS in diagnosing esophageal cancer was verified;the expression of serum SPINK1 and SPP1 was compared among the esophageal cancer group,benign lesion group,and healthy control group;the relationship between the expression of serum SPINK1 and SPP1 in esophageal cancer patients and their clinical and pathological characteristics was explored;efficacy of EUS combined with serum SPINK1,SPP1 levels for early diagnosis of esophageal cancer was analyzed using receiver operator characteristic curve(ROC curve).Results Compared with the gold standard,the results of EUS examination showed that 81 cases were diagnosed with esophageal cancer,79 cases were diagnosed with benign lesions,11 cases were missed diagnosed,and 10 cases were misdiagnosed,with an accuracy rate of 88.40%(160/181);Compared with the healthy control group and the benign lesion group,the expression levels of serum SPINK1 and SPP1 in the esophageal cancer group were obviously increased,the expression levels of serum SPINK1 and SPP1 in the benign lesion group were significantly higher than those in the healthy control group,the differences were statistically significant(P<0.05);Serum SPINK1 expression was linked to tumor diameter>2 cm,presence of lymph node metastasis,lymph node positivity,and tissue grading level 3 in patients(P<0.05).Serum SPP1 expression level was related to tumor diameter>2 cm,presence of lymph node metastasis,lymph node positivity,and estrogen receptor positivity of patients(P<0.05);ROC curve showed that the area under the curve(AUC)of EUS,serum SPINK1,SPP1 levels,and their combination in the early diagnosis of esophageal cancer was 0.862,0.834,0.782,and 0.926,respectively,the clinical efficacy of the combination of the three in the early diagnosis of esophageal cancer was superior to that of EUS,serum SPINK1,and SPP1 alone(Z=2.30,Z=3.70,Z=4.23,P=0.022,P=0.000,P=0.000).Conclusion The expression levels of serum SPINK1 and SPP1 in esophageal cancer patients are abnormally up-regulated.The combination of EUS and serum SPINK1 and SPP1 has high clinical value in early diagnosis of esophageal cancer.

Outpatient humanistic care refered to providing a full process of caring medical services to outpatients. In order to standardize the human caring services for outpatients in medical institutions, promote the comprehensive service level of outpatient services, and improve the patient′s medical experience, Chinese Association for Life Care issued the group standard of Management Norms for Human caring of Outpatients in April 2023. This standard clarified the relevant terms and definitions of human caring for outpatients, specified the basic requirements for human caring, the humanistic quality and care responsibilities of outpatient staff, the outpatient care environment and facilities, the outpatient care process and measures, and quality management. It designed standardized and personalized full process care service norms, providing references for medical institutions at all levels to promote the development of human caring for outpatients.

Background/Aims: Four-week treatment of linvencorvir (RO7049389) was generally safe and well tolerated, and showed anti-viral activity in chronic hepatitis B (CHB) patients. This study evaluated the efficacy, safety, and pharmacokinetics of 48-week treatment with linvencorvir plus standard of care (SoC) in CHB patients. Methods: This was a multicentre, non-randomized, non-controlled, open-label phase 2 study enrolling three cohorts: nucleos(t)ide analogue (NUC)-suppressed patients received linvencorvir plus NUC (Cohort A, n=32); treatment-naïve patients received linvencorvir plus NUC without (Cohort B, n=10) or with (Cohort C, n=30) pegylated interferon-α (Peg-IFN-α). Treatment duration was 48 weeks, followed by NUC alone for 24 weeks. Results: 68 patients completed the study. No patient achieved functional cure (sustained HBsAg loss and unquantifiable HBV DNA). By Week 48, 89% of treatment-naïve patients (10/10 Cohort B; 24/28 Cohort C) reached unquantifiable HBV DNA. Unquantifiable HBV RNA was achieved in 92% of patients with quantifiable baseline HBV RNA (14/15 Cohort A, 8/8 Cohort B, 22/25 Cohort C) at Week 48 along with partially sustained HBV RNA responses in treatment-naïve patients during follow-up period. Pronounced reductions in HBeAg and HBcrAg were observed in treatment-naïve patients, while HBsAg decline was only observed in Cohort C. Most adverse events were grade 1–2, and no linvencorvir-related serious adverse events were reported. Conclusions 48-week linvencorvir plus SoC was generally safe and well tolerated, and resulted in potent HBV DNA and RNA suppression. However, 48-week linvencorvir plus NUC with or without Peg-IFN did not result in the achievement of functional cure in any patient.

Objective: Autism spectrum disorder (ASD) is a neurodevelopmental disorder with onset in infancy. Early intervention is critical to improve the prognosis for these children. E-health interventions have tremendous potential. This review aimed to determine the status and effectiveness of family interventions for parents of children aged 0–6 years with ASD in the context of e-health. Methods: The review methodology was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. PubMed, Web of Science, and China National Knowledge Infrastructure were searched from inception to June 2022. The searches were limited to children with ASD of the age range between 0 and 6 years. We collated the available information and used descriptive statistics to analyze the synthesized data. Results: Our initial search identified 3,672 articles, of which 30 studies met the inclusion criteria. The 30 articles selected were released between 2012 and 2022. All articles are in English. Most articles reviewed were from high-income countries (27/30, 90.0%), especially from the United States (16/30, 53.3%). Four major themes emerged from the 30 studies that matched the inclusion criteria, as follows: 1) type of e-health interventions, 2) duration of interventions, 3) clinical aspects of e-health interventions, and 4) evidence for intervention effectiveness, looking into the positive, negative, and mixed findings of previous studies. Conclusion These findings suggest that a wide variety of e-health interventions may actually help support both children with ASD aged 0–6 years and their parents.

To report a case of Noonan-like syndrome with loose anagen hair, and to detect gene mutations in the family. A 3-year-old female patient presented with a special facial appearance, short stature, deep palmar and plantar creases, and dark skin. The scalp hair was sparse and thin, dermoscopy showed black spot sign, single-hair follicular units, hair shafts varying in the diameter, upright hair and new vellus hair, and constriction of hair shafts and nodular hair were occasionally observed. Peripheral blood samples were collected from the proband and her parents, and the genomic DNA was extracted for whole-exome sequencing. A heterozygous missense mutation c.4A>G was identified in exon 2 of the SHOC2 gene in the proband, resulting in the substitution of serine by glycine at amino acid position 2 (p.S2G) . The mutation was not identified in either of her parents. Combined with the clinical phenotype and gene mutation, the diagnosis of Noonan-like syndrome with loose anagen hair was confirmed.

Matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) is a new imaging technique with label-free, rapid, and high throughput features. It has bloomed in the analysis on the spatial distribution of biomolecules such as drugs, metabolites, peptides and proteins on the tissue surface in virtue of providing high data throughput from non-targeted full analysis and high accuracy from targeted analysis. The acquisition of MSI signal response with high sensitivity, high spatial resolution, and good stability is directly depended on the appropriate sample preparation approaches, and flexible and various data processing tools will help the non-target data mining to meet the demands of visualization, spatial distribution and multiple index applications so as to reveal the scientific rules beneath the data. This review briefly summarizes the key advances in MALDI-MSI from aspects of sample preparation procedures, data processing and visualization. It also illustrates the characteristics, difficulties and probable solutions derived from these key techniques.

The objective of present study was to develop a simple and reliable voiding spot assay (VSA) system to evaluate the lower urinary tract function of mice, and to establish it as a standardized protocol. Ultraviolet (UV) light was used to screen out the filter paper without autofluorescence and with optimal urine diffusion properties. Next, the appropriate wavelength of UV was determined based on the quality of the photographic image of urine spots on the filter paper. To confirm that the urine stain area on the filter paper was correlated with the amount of urine, a volume-area standard curve was constructed. The utility of this VSA system was validated using female wild-type C57BL/6J mice aged 12-13 weeks, and the data generated under identical procedural settings were compared among laboratories. Furthermore, this VSA system was employed to analyze the changes in voiding patterns in mice with urinary tract infections or transportation stress. No. 4 filter paper with a thickness of 0.7 mm was identified as the most suitable material for VSA, exhibiting no autofluorescence and facilitating optimal urine diffusion. The filter paper retained its integrity during the assay, and there was a linear correlation between urine volume and stained area under 365 nm UV light. Utilizing this VSA system, we determined that female wild-type C57BL/6J mice produced approximately 695.8 μL total urine and 5.5 primary voiding spots (PVS) with an average size of 126.4 μL/spot within 4-h period. Over 84% of PVS volumes ranged from 20 to 200 μL. Notably, PVS volumes of mice were similar across different laboratories. Mice with urinary tract infections or transportation stress exhibited significant changes in VSA parameters, including increased voiding frequency, PVS number, and decreased PVS volume. Therefore, this VSA system can be used to evaluate the urinary function of normal mice, as well as those with urinary tract infection or transportation stress.

Objective:To study the safety and efficacy of laparoscopic subtotal distal pancreatectomy using the arterial first approach in treatment of patients with pancreatic neck-body cancer after neoadjuvant chemotherapy.Methods:The clinical data of patients who underwent laparoscopic subtotal distal pancreatectomy after neoadjuvant chemotherapy at the Department of Pancreatic Surgery, Hunan Provincial People's Hospital from January 2019 to June 2021 were analyzed retrospectively. Seven patients were included in this study. There were 3 males and 4 females, aged 55(46, 67) years old. The clinical data analysed included chemotherapy, preoperative, intraoperative, postoperative and follow-up data. Follow up was done by outpatient visits, or contact using wechat or telephone.Results:Five borderline staged patients were treated with the AG chemotherapy regimen (gemcitabine+ albumin-bound paclitaxel), and two patients with locally advanced stage were treated with the mFOLFIRINOX chemotherapy regimen (oxaliplatin+ irinotecan+ calcium folate+ fluorouracil). All the 7 patients underwent portal vein/superior mesenteric vein resection and reconstruction using the superior mesenteric artery priority approach. The operation time was 400(350, 440) min, and the intraoperative blood loss was 300(150, 400) ml. Postoperative complications occurred in 2 patients with grade B pancreatic fistula and refractory ascites in 1 patient each. The postoperative hospital stay was 11(10, 14) days. All 7 patients underwent R 0 resection. During a follow-up period of 9 to 33 months, 5 patients were still alive without tumor, 1 patient survived with tumor, and 1 patient had died of recurrence. Conclusion:In selected cases, laparoscopic subtotal distal pancreatectomy for pancreatic neck-body cancer after neoadjuvant chemotherapy was safe and feasible.

Objective: To investigate the brain function and their correlation with sleep beliefs and attitudes in adolescents with drug naive insomnia by using fractional amplitude of low frequency fluctuation, so as to provide a reference for the mechanism and treatment of insomnia. Methods: An insomnia group ( n =21) recruited first episode, drug naive, adolescents with insomnia who met the diagnostic criteria of the American Diagnostic and Statistical Manual of Mental Disorders(DSM-V). Healthy subjects matched with age, gender, and educational background were selected as the control group ( n =20). Pittsburgh Sleep Quality Index Scale (PSQI), Brief Version of Dysfunctional Beliefs and Attitudes about Sleep (DBAS-16), 24 Items Hamilton Depression Scale (HAMD-24), 14 Items Hamilton Anxiety Scale (HAMA-14) were evaluated. Fractional amplitude of low frequency fluctuation was used for analysis, and Pearson correlation analysis was employed to quantify the correlation between peak values of brain regions with significant differences and the clinical scale scores of the two groups. Results: Compared with the control group, ractional amplitude of low frequency fluctuation(fALFF) values in the insomnia group were significantly decreased ( P <0.01, Alphaism corrected) in the left dorsolateral prefrontal lobe (L-DLPFC, MNI coordinates: -12, 60, 21, t =-3.85, K =495) and the left precuneus (MNI coordinates: -3, -54, 51, t =-4.29, K =417). The fALFF value of L-DLPFC in the insomnia group was positively correlated with DBAS-16 score ( r= 0.47 , P = 0.04 ). Conclusion Abnormalities in the L-DLPFC region suggest that adolescents with insomnia may suffer from impaired regulation of emotional and cognitive activities related to sleep.
