Objective To analyze the trend of influenza epidemic intensity in Urumqi City, Xinjiang, in early 2023, and to provide a reference basis for influenza surveillance, prevention and control. Methods Based on the daily number of influenza cases in Urumqi from January 1, 2023 to March 26, 2023, a generalized linear model was established to correlate the cumulative number of cases with the number of days of illness, and the corresponding doubling time was calculated. Results A total of 9 243 influenza cases were included in this study, including 7733 confirmed cases and 1510 suspected cases. The peak incidence of influenza occurred in March, and 6039 positive cases were detected, with a positivity rate of 78.09%. The age group of 3-6 years old had the highest proportion of influenza positive cases, accounting for 32.20%. The longest doubling time among confirmed cases was 13.49 (95% CI:11.95-15.47) in stage 2 (January 22 to February 13), and the shortest was in stage 3 (February 14 to March 26), which was 9.41 (95% CI:8.24-10.91). Conclusion The shorter the doubling time, the faster the speed of influenza transmission, and it is necessary to strengthen the prevention and control of influenza in winter and spring.

Based on the principle of molecular hybridization, fifteen compounds were designed and synthesized through the combination of aminothiazoloxime and phosphonate fragment. The results showed that these compounds had better inhibitory effects on the tested bacteria. In particular, the activities of compounds Ⅲf and Ⅲi against S. aureus, E. coli, methicillin-resistant S. aureus (MRSA) and fluoroquinolone-resistant E. coli (FREC) were the most significant, the minimal inhibitory concentration (MIC) of Ⅲf was 1, 8, 4, 16 μg·mL^-1 respectively, and the MIC of Ⅲi was 4, 4, 16, 8 μg·mL^-1 respectively, which were slightly lower than that of the control drug oxacillin, and their anti-E. coli, MRSA and FREC activities were superior to that of the control drug oxacillin. Their activities to S. aureus were close to that of oxacillin, and to E. coli, MRSA and FREC were superior to that of oxacillin, which is worthy of further study.

Objective:To investigate the clinical efficacy of five-element music therapy in the treatment of bipolar disorder.Methods:Eighty patients with bipolar disorder admitted to Shandong Mental Health Center from January 2018 to December 2019 were included in this study. They were randomly divided into a study group and a control group ( n = 40/group). The control group was treated with conventional drug treatment. The study group was treated with five-element music therapy based on conventional drug treatment. Before, during and after treatment, mania and depression were evaluated. Symptom self-evaluation scale and the Traditional Chinese Medicine Five State Emotion Questionnaire were completed to evaluate the curative effect. Patients were followed up by telephone call. Recurrence at 3, 6 and 12 months was recorded. Results:Before treatment, there were no significant differences in the scores of the Bech-Rafaelsen Mania Rating Scale (BRMs), Hamilton Depression Rating Scale (HAMD), Traditional Chinese Medicine Five State Emotion Questionnaire, Symptom Checklist-90 (SCL-90) between the two groups (all P > 0.05). During and after treatment, BRMs, HAMD, Traditional Chinese Medicine Five State Emotion Questionnaire, and SCL-90 scores were significantly decreased in each group compared with before treatment [Control group: BRMs score during and after treatment: (11.52 ± 1.57) points, (9.43 ± 1.05) points; HAMD score during and after treatment: (16.75 ± 3.05) points, (13.61 ± 2.51) points; Traditional Chinese Medicine Five State Emotion Questionnaire: emotional vocabulary (67.25 ± 5.7) points, (56.38 ± 4.97) points, physical symptoms (29.52 ± 3.94) points, (24.19 ± 3.05) points, SCL-90 score: (100.52 ± 10.26) points, (68.85 ± 7.33) points. Study group: BRMs score during and after treatment: (9.33 ± 1.09) points, (7.85 ± 0.82) points; HAMD score: (13.74 ± 2.54) points, (10.17 ± 1.97) points; Traditional Chinese Medicine Five State Emotion Questionnaire: emotional vocabulary: (58.19 ± 5.06) points, (46.85 ± 4.06) points, physical symptoms (25.14 ± 3.54) points, (20.11 ± 2.57) points; SCL-90 scores: (90.85 ± 8.97) points, (56.87 ± 5.81) points]. During and after treatment, scores of BRMs, HAMD, Traditional Chinese Medicine Five State Emotion Questionnaire and SCL-90 in the study group were significantly lower than those in the control group ( t = 3.77, 7.01, 4.48, 6.99, 8.78, 4.89, 6.05, 4.19, 7.57, all P < 0.05). Total response rate in the study group was significantly higher than that in the control group (90.0% vs. 72.5%, χ2 = 4.02, P < 0.05). At 3, 6 and 12 months after treatment, recurrence rate in the study group was 2.5%, 15.0% and 30.0%, respectively, which were significantly lower than 17.5%, 35.0%, and 52.5% in the control group ( χ2 = 5.00, 4.26, 4.17, all P < 0.05). Conclusion:Five-element music therapy for the treatment of bipolar disorder can markedly alleviate depression and mania, restore patient's emotional state, improve clinical efficacy, and decrease recurrence rate.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.

Background There is a lack of research evidence on the association between sugar-sweetened beverage (SSB) consumption and gestational diabetes mellitus (GDM) in China. Objective To explore the association between frequency of SSB consumption before pregnancy and risk of GDM in pregnant women in Shaanxi Province, and to provide a scientific basis for targeted interventions to control maternal blood glucose. Methods The recruitment to the China Birth Cohort study started in October 2020. Pregnant women at 6-16 weeks who had their first prenatal examination at five hospitals in Shaanxi Province were recruited. A maternal health questionnaire was used to collect basic information about pregnant women. A semi-quantitative food frequency questionnaire was used to collect the consumption of carbonated beverages, fruit and vegetable juice beverages, coffee beverages, and milk tea beverages in one year before pregnancy, which were summed to obtain the SSB consumption. Pregnant women were divided into three groups according to SSB consumption, namely <1 serving·week⁻¹, 1-4 servings·week⁻¹, and ≥5 servings·week⁻¹. GDM was confirmed by oral glucose tolerance test (OGTT) between 24-28 weeks of gestation. A binary logistic regression model was applied to explore the association between SSB consumption and risk of GDM. Multiple linear regression was applied to investigate the associations between SSB consumption (per 1-serving·d⁻¹ increase) and OGTT fasting plasma glucose, 1-hour glucose, and 2-hour glucose. Results A total of 3811 pregnant women were finally enrolled in this study, of which 752 developed GDM, with an incidence rate of 19.7%. The incidence rates of GDM in pregnant women with SSB consumption frequency of <1 serving·week⁻¹, 1-4 servings·week⁻¹, and ≥5 servings·week⁻¹ were 18.0%, 21.1%, and 26.8%, respectively. After adjusting for maternal age, pre-pregnancy body mass index (BMI), education, number of children born, family history of diabetes, smoking, alcohol consumption, physical activity level, and total energy intake, the risk of GDM increased by 26% (OR=1.26, 95%CI: 1.05, 1.50) in the 1-4 servings·week⁻¹ group and by 76% (OR=1.76, 95%CI: 1.31, 2.38) in the ≥5 servings·week⁻¹ group compared to the <1 serving·week⁻¹ SSB consumption group, respectively. Further stratified analysis revealed no interaction effect (P_interaction>0.05) between SSB consumption and maternal age, pre-pregnancy BMI, or first labor or not. For each additional SSB consumption per day, the risk of GDM increased by 94% (OR=1.94, 95%CI: 1.37, 2.75); and the maternal OGTT 1-hour glucose and 2-hour glucose increased by 0.33 mmol·L⁻¹ and 0.18 mmol·L⁻¹, respectively (P<0.05), and no significant increase in fasting plasma glucose was found (P>0.05). Conclusion Higher SSB consumption before pregnancy increases the risk of GDM in pregnant women.

Objective:To investigate the clinical, pathological and genetic characteristics of myopathy-type very long chain acyl-coenzyme A dehydrogenase deficiency (VLCADD).Methods:The detailed clinical data, muscle biopsy pathology and molecular results of 4 patients with genetically confirmed myopathy-type VLCADD admitted to Henan Provincial People′s Hospital and Xuanwu Hospital, Capital Medical University from June 2014 to November 2019 were retrospectively analyzed.Results:All of the 4 patients were late-onset myopathy-type VLCADD. The onset age ranged from 13 to 16 years, with a mean age of 14.5 years. The age at diagnosis ranged from 21 to 54 years, with a mean age of 42.5 years. The main clinical manifestation was repeated rhabdomyolysis, including myalgia, weakness and dark urine. Obvious somnolence was observerd in 1 patient. Muscle biopsy pathology revealed mild lipid accumulation, without vacuoles. Six ACADVL variations were detected in the 4 patients, including c.1283G>A (p.R428H), c.1532G>A (p.R511Q), c.833_835delAGA (p.K278del), c.1843C>T (p.R615 *), c.1748C>T (p.S583L) and c.1391C>T (p.T464I),among which c.1391C>T (p.T464I) was a novel variation, predicted to be likely pathogenic. Other 5 variations were reported pathogenic variations. Conclusions:Myopathy-type VLCADD is characterized by paroxysmal rhabdomyolysis and can be associated with somnolence. There is no specificity in muscle pathology. There are ACADVL variations, among which c.1391C>T is a novel variation.

OBJECTIVE: To investigate the effect of phorbol-12-myristate-13-ace-tate (TPA) on the proliferation and apoptosis of acute promyelocytic leukemia cell line NB4 and its molecular mechanism. METHODS: The effect of different concentrations of TPA on the proliferation of NB4 cells at different time points was detected by CCK-8 assay. The morphological changes of NB4 cells were observed by Wright-Giemsa staining. The cell cycle and apoptosis of NB4 cells after TPA treatment were detected by flow cytometry. The mRNA expressions of NB4 cells after TPA treatment were analyzed by high-throughput microarray analysis and real-time quantitative PCR. Western blot was used to detect the protein expression of CDKN1A, CDKN1B, CCND1, MYC, Bax, Bcl-2, c-Caspase 3, c-Caspase 9, PIK3R6, AKT and p-AKT. RESULTS: Compared with the control group, TPA could inhibit the proliferation of NB4 cells, induce the cells to become mature granulocyte-monocyte differentiation, and also induce cell G₁ phase arrest and apoptosis. Differentially expressed mRNAs were significantly enriched in PI3K/AKT pathway. TPA treatment could increase the mRNA levels of CCND1, CCNA1, and CDKN1A, while decrease the mRNA level of MYC. It could also up-regulate the protein levels of CDKN1A, CDKN1B, CCND1, Bax, c-Caspase 3, c-Caspase 9, and PIK3R6, while down-regulate MYC, Bcl-2, and p-AKT in NB4 cells. CONCLUSION TPA induces NB4 cell cycle arrest in G₁ phase and promotes its apoptosis by regulating PIK3/AKT signaling pathway.

This study aimed to elucidate the effect and underlying mechanism of Bovis Calculus in the treatment of ulcerative colitis(UC) through network pharmacological prediction and animal experimental verification. Databases such as BATMAN-TCM were used to mine the potential targets of Bovis Calculus against UC, and the pathway enrichment analysis was conducted. Seventy healthy C57BL/6J mice were randomly divided into a blank group, a model group, a solvent model(2% polysorbate 80) group, a salazosulfapyridine(SASP, 0.40 g·kg~(-1)) group, and high-, medium-, and low-dose Bovis Calculus Sativus(BCS, 0.20, 0.10, and 0.05 g·kg~(-1)) groups according to the body weight. The UC model was established in mice by drinking 3% dextran sulfate sodium(DSS) solution for 7 days. The mice in the groups with drug intervention received corresponding drugs for 3 days before modeling by gavage, and continued to take drugs for 7 days while modeling(continuous administration for 10 days). During the experiment, the body weight of mice was observed, and the disease activity index(DAI) score was recorded. After 7 days of modeling, the colon length was mea-sured, and the pathological changes in colon tissues were observed by hematoxylin-eosin(HE) staining. The levels of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), interleukin-6(IL-6), and interleukin-17(IL-17) in colon tissues of mice were detected by enzyme-linked immunosorbent assay(ELISA). The mRNA expression of IL-17, IL-17RA, Act1, TRAF2, TRAF5, TNF-α, IL-6, IL-1β, CXCL1, CXCL2, and CXCL10 was evaluated by real-time polymerase chain reaction(RT-PCR). The protein expression of IL-17, IL-17RA, Act1, p-p38 MAPK, and p-ERK1/2 was investigated by Western blot. The results of network pharmacological prediction showed that Bovis Calculus might play a therapeutic role through the IL-17 signaling pathway and the TNF signaling pathway. As revealed by the results of animal experiments, on the 10th day of drug administration, compared with the solvent model group, all the BCS groups showed significantly increased body weight, decreased DAI score, increased colon length, improved pathological damage of colon mucosa, and significantly inhibited expression of TNF-α,IL-6,IL-1β, and IL-17 in colon tissues. The high-dose BCS(0.20 g·kg~(-1)) could significantly reduce the mRNA expression levels of IL-17, Act1, TRAF2, TRAF5, TNF-α, IL-6, IL-1β, CXCL1, and CXCL2 in colon tissues of UC model mice, tend to down-regulate mRNA expression levels of IL-17RA and CXCL10, significantly inhibit the protein expression of IL-17RA,Act1,and p-ERK1/2, and tend to decrease the protein expression of IL-17 and p-p38 MAPK. This study, for the first time from the whole-organ-tissue-molecular level, reveals that BCS may reduce the expression of pro-inflammatory cytokines and chemokines by inhibiting the IL-17/IL-17RA/Act1 signaling pathway, thereby improving the inflammatory injury of colon tissues in DSS-induced UC mice and exerting the effect of clearing heat and removing toxins.

Objective: To investigate the molecular characteristics of ciprofloxacin-cefotaxime-azithromycin co-resistant Salmonella enterica serovar Thompson (S. Thompson) isolates from sporadic cases of foodborne diseases and aquatic foods in Hunan province. Methods: Ciprofloxacin-cefotaxime-azithromycin co-resistant S. Thompson isolates were selected from samples, and broth microdilution method was used to determine the resistance to 11 antibiotics of these isolates in vitro. Whole genome sequencing was used for investigating antimicrobial resistance gene patterns and phylogenetic relationships of strains. Results: Nine ciprofloxacin-cefotaxime-azithromycin co-resistant isolates were recovered from 19 S. Thompson isolates. Among nine ciprofloxacin-cefotaxime-azithromycin co-resistant isolates, eight of them harbored IncC plasmids, simultaneously carrying plasmid-mediated quinolone resistance (PMQR) genes qepA and qnrS1, β-lactamase resistance gene bla_CMY-2, azithromycin resistance gene mph(A), and one isolate harbored IncR plasmid, and carried PMQR genes qnrB4 and aac(6')-Ib-cr, bla_OXA-10 and mph(A). Genetic environment analysis showed that qnrS1, qepA, mph(A) and bla_CMY-2 genes might be integrated on genomes of strains by ISKra4, IS91, IS6100 and ISEcp1, respectively. Phylogenetic core genome comparisons demonstrated that ciprofloxacin-cefotaxime-azithromycin co-resistant isolates from patients and aquatic foods were genetically similar and clustered together. Conclusion: Ciprofloxacin-cefotaxime-azithromycin co-resistant S. Thompson isolates have been isolated from both human and aquatic food samples, suggesting that the spread of multidrug resistant Salmonella between human and aquatic animals.
