OBJECTIVE: To observe the effects of Tiaoshu Anshen (regulating the hinge and calming the mind) acupuncture on sleep quality and serum levels of 5-hydroxytryptamine (5-HT) and dopamine (DA) in patients with chronic insomnia. METHODS: A total of 58 patients with chronic insomnia were randomly divided into an acupuncture group and a medication group, 29 cases in each group. Tiaoshu Anshen acupuncture was applied at Baihui (GV20) and bilateral Shenmen (HT7), Sanyinjiao (SP6), Benshen (GB13) in the acupuncture group, once a day, 1-day interval was taken after 6 consecutive days of treatment. Estazolam tablet was given orally before bed in the medication group, 1 mg each time. The 4-week treatment was required in both groups. Before and after treatment, the sleep quality was assessed by Pittsburgh sleep quality index (PSQI) and polysomnography (PSG), the serum levels of 5-HT and DA were detected by ELISA. RESULTS: After treatment, the item scores and total scores of PSQI were decreased compared with those before treatment in the two groups (P<0.05); in the acupuncture group, the scores of sleep quality, sleep latency, sleep time, sleep efficiency, sleep disorders and total score of PSQI were lower than those in the medication group (P<0.05). After treatment, the total sleep time (TST) was prolonged (P<0.05), the sleep latency (SL) and wake after sleep onset (WASO) were shortened (P<0.05), the sleep efficiency (SE%), percentage of non-rapid eye movement stage 3 (N3%), percentage of rapid eye movement stage (REM%) and serum levels of 5-HT were increased (P<0.05) compared with those before treatment; the percentage of non-rapid eye movement stage 1 (N1%), percentage of non-rapid eye movement stage 2 (N2%) and serum levels of DA were decreased (P<0.05) compared with those before treatment in the two groups. After treatment, in the acupuncture group, TST was longer, while SL and WASO were shorter than those in the medication group (P<0.05), SE%, N3%, REM% and serum level of 5-HT were higher, while N1%, N2% and serum level of DA were lower than those in the medication group (P<0.05). CONCLUSION Tiaoshu Anshen acupuncture may improve the sleep quality by regulating the serum neurotransmitter levels i.e. 5-HT and DA in patients with chronic insomnia.

BACKGROUND:Sepsis is one of the main causes of mortality in intensive care units(ICUs).Early prediction is critical for reducing injury.As approximately 36%of sepsis occur within 24 h after emergency department(ED)admission in Medical Information Mart for Intensive Care(MIMIC-IV),a prediction system for the ED triage stage would be helpful.Previous methods such as the quick Sequential Organ Failure Assessment(qSOFA)are more suitable for screening than for prediction in the ED,and we aimed to find a light-weight,convenient prediction method through machine learning. METHODS:We accessed the MIMIC-IV for sepsis patient data in the EDs.Our dataset comprised demographic information,vital signs,and synthetic features.Extreme Gradient Boosting(XGBoost)was used to predict the risk of developing sepsis within 24 h after ED admission.Additionally,SHapley Additive exPlanations(SHAP)was employed to provide a comprehensive interpretation of the model's results.Ten percent of the patients were randomly selected as the testing set,while the remaining patients were used for training with 10-fold cross-validation. RESULTS:For 10-fold cross-validation on 14,957 samples,we reached an accuracy of 84.1%±0.3%and an area under the receiver operating characteristic(ROC)curve of 0.92±0.02.The model achieved similar performance on the testing set of 1,662 patients.SHAP values showed that the five most important features were acuity,arrival transportation,age,shock index,and respiratory rate. CONCLUSION:Machine learning models such as XGBoost may be used for sepsis prediction using only a small amount of data conveniently collected in the ED triage stage.This may help reduce workload in the ED and warn medical workers against the risk of sepsis in advance.

OBJECTIVE: To explore the genetic etiology of a child with D bifunctional protein deficiency (DBPD) born to a consanguineous pedigree. METHODS: A child with DBPD who was admitted to the First Affiliated Hospital of Hainan Medical College on January 6, 2022 due to hypotonia and global developmental delay was selected as the study subject. Clinical data of her pedigree members were collected. Peripheral blood samples of the child, her parents and elder sisters were collected and subjected to whole exome sequencing. Candidate variant was validated by Sanger sequencing and bioinformatic analysis. RESULTS: The child, a 2-year-and-9-month-old female, had featured hypotonia, growth retardation, unstable head lift, and sensorineural deafness. Serum long-chain fatty acids were elevated, and auditory brainstem evoked potentials had failed to elicit V waves in both ears with 90 dBnHL stimulation. Brain MRI revealed thinning of corpus callosum and white matter hypoplasia. The child's parents were secondary cousins. Their elder daughter had a normal phenotype and no clinical symptoms related to DBPD. Elder son had frequent convulsions, hypotonia and feeding difficulties after birth, and had died one and a half month later. Genetic testing revealed that the child had harbored homozygous c.483G>T (p.Gln161His) variants of the HSD17B4 gene, for which both of her parents and elder sisters were carriers. Based on the guidelines from the American College of Medical Genetics and Genomics, the c.483G>T (p.Gln161His) was rated as a pathogenic variant (PM1+PM2_Supporting+PP1+PP3+PP4). CONCLUSION The homozygous c.483G>T (p.Gln161His) variants of the HSD17B4 gene caused by the consanguineous marriage probably underlay the DBPD in this child.

Objective:To analyse the changes in color Doppler and contrast-enhanced ultrasound (CEUS) blood flow parameters in patients with septic acute kidney injury (AKI) from the perspective of macroscopic circulation and microscopic circulation perfusion, in order to explore the value of clinical application of ultrasound in this disease.Methods:A total of 53 ICU-admitted patients diagnosed with septic AKI at the Second Affiliated Hospital of Soochow University from January 2021 to May 2022 were selected.Patients with septic AKI were classified into stages 1-3 according to the 2012 Kidney Disease: Improving Global Outcomes (KDIGO) AKI diagnostic criteria, with stage 1 being the mild group(17 cases), stages 2 and 3 being the severe group(21 cases), and septic patients without AKI in the same period being the control group(15 cases). The ultrasound parameters such as the relative blood flow(RBF) and time-averaged velocity(TAV) of the renal artery as well as the cardiac output (CO) and cardiac index (CI) in the macroscopic circulation were measured, and the time-intensity curve was analysed by the CEUS analysis software to calculate the microscopic parameters such as time to peak(TTP), rise time(RT), fall half time(FHT) and mean transit time(MTT), and the cardiac output and cardiac index were also measured. The differences in ultrasound Doppler and CEUS parameters among the various groups were compared. The diagnostic effectiveness of each parameter for severe AKI was assessed using ROC curve analysis.Results:①In macrocirculation, the renal blood flow (RBF) and time-averaged velocity (TAV) gradually decreased ( P=0.004, P<0.001) as the disease progressed in AKI patients. But the difference of CO and CI among the three groups were not statistically significant in each group ( P=0.17, 0.12). ②In microcirculation, the renal interlobar artery Doppler parameters pulsatility index (PI), resistance index (RI), and systolic/diastolic flow ratio (S/D) gradually increase in patients with septic AKI ( P<0.05) and the CEUS parameters TTP, RT, FHT and MTT were prolonged ( P<0.001, P=0.003, P=0.004, P=0.009). ③The combined diagnosis of RI and TTP was more beneficial in diagnosing septic AKI in critically ill patients [AUC=0.93(0.85-1.00)]. Conclusions:Color Doppler ultrasound combined with CEUS can detect reduced macroscopic and microscopic circulation in patients with septic AKI, especially in those with severe AKI, and this is independent of changes in CO or CI.

A 77-years-old female patient presented gross hematuria for one week, and CT showed a mass in the left kidney. Ureteroscopy detected a left renal mass. Laparoscopic nephroureterectomy was performed and pathology showed the tumor was mainly located in the renal parenchyma, with glomeruli around the tumor cells. Urothelium showed no obvious dysplasia or clear migration of tumor cells. Considering both the clinical symptoms, and squamous cell carcinoma not detecting in other locations of the patient, primary renal parenchyma was confirmed. Three months after surgery, CT detected recurrence in the operating area, with metastasis to the adjacent abdominal cavity and aorta lymph node.

Objective:To investigate the effects of Bcl3 gene knockout on the composition of spleen immune cells and antitumor ability of mice.Methods:Bcl3 gene knockout mice (Bcl3 -/-) were established by CRISPR/Cas9 genome editing technology. Blood routine test and flow cytometry were used to detect the immune cell composition in Bcl3 -/- mice. Lung metastasis models were established by injecting mice with B16F10 melanoma cells. The number of tumor nodules in lung and the survival time of mice were used to assess the antitumor ability of wild-type (WT) and Bcl3 -/- mice. Results:Bcl3 -/- mice were successfully bred to a strain with normal growth rate and normal breeding performance. Furthermore, no embryonic death occurred. Compared with WT mice, Bcl3 -/- mice showed splenomegaly and a significant increase in the number of spleen immune cells ( P<0.05). The counts and percentages of platelets and neutrophils in Bcl3 -/- mice were significantly lower than those in WT mice. The proportion of CD19 + B cells showed no significant change, while the proportions of CD3 + T cells and T cell subsets (CD4 + , CD8 + , Treg) increased significantly ( P<0.05). The proportions of NK cells (NK1.1 + ) and neutrophils (Gr1 + ) decreased ( P<0.05), while no significant change in the proportion of DC (CD11b + ) was observed. There were a large number of tumor nodules formed by melanoma cells in the lung of Bcl3 -/- tumor bearing mice, and their survival time was shortened dramatically. Conclusions:Knockout of Bcl3 gene affected the development, differentiation and function of immune cells, thereby reducing the antitumor ability of mice.

Objective To investigate the clinicopathological characteristics and prognosis of patients with Borrmann type Ⅳ gastric cancer. Methods A cohort retrospective analysis of 2386 patients with gastric cancer who underwent radical surgery was used to screen out Borrmann type Ⅳ patients, and analyze their clinical features and prognostic factors. Results Among 2386 patients with gastric cancer, 363 cases (15.21%) were Borrmann type Ⅳ. Compared with non-Borrmann type Ⅳ gastric cancer patients, Borrmann type Ⅳ patients had higher rates of simultaneous liver metastasis, metachronous liver metastasis, lymph node metastasis and vascular infiltration. Moreover, the age of onset tended to be younger and the pathological type tended to be poorly differentiated-undifferentiated (all P < 0.05). The 5-year OS of the entire group was 49.32% and the 5-year DFS was 44.61%. There were significant differences in 5-year OS and DFS between Borrmann type Ⅳ and non-Borrmann type Ⅳpatients (all P < 0.001). The subgroup analyses showed that there were statistically significant differences in 5-year OS and DFS of gastric cancer patients between Borrmann type Ⅳ and non-Borrmann type Ⅳ in pT2-pT4a and pN0-pN3a stages (all P < 0.005). Multivariate analysis showed that the poorly differentiated-undifferentiated tumor, the T4a-pT4b stage of tumor invasion depth, lymph node metastasis, the ⅢA-ⅢC pTNM stage of the tumor, postoperative liver metastasis and peritoneal metastasis were independent risk factors affecting the prognosis of Borrmann type Ⅳ gastric cancer patients (all P < 0.05). Conclusion Borrmann type Ⅳ gastric cancer is prone to liver metastasis, lymph node metastasis, peritoneal metastasis and poor prognosis, and it's prognosis is affected by a variety of independent risk factors.
