Objective To observe the role of dried tangerine peel in Yigong Powder improves iron metabolism and promotes red blood cell generation in anemia of chronic disease (ACD).Methods With a two-by-two factorial design,the Yigong Powder was divided into dried tangerine peel and Chenpi absent Decoction. According to the random number table method,32 zymosan-induced generalized inflammation (ZIGI) mice were randomly divided into the model group,the dried tangerine peel group,the Chenpi absent Decoction group,and the Yigong Powder group. The dried tangerine peel group,Chenpi absent Decoction group and the Yigong Powder group were given dried tangerine peel(3.083 g/kg),Chenpi absent Decoction(12.33g/kg),and Yigong Powder(15.413g/kg)by gavage to the corresponding group of mice. The model group was given an equal amount of physiological saline by gavage,and treated continuously for 7 days. After the completion of administration,the body weight of each group of mice was recorded. The hemoglobin content of each group of mice was detected using a fully automatic cell counter,the serum iron content was detected using colorimetry,the serum ferritin content was detected using enzyme-linked immunosorbent assay (ELISA),and the spleen index was calculated. The liver tissue inflammatory factors interleukin-1β (IL-1β),interleukin-6 (IL-6),tumor necrosis factor-α (TNF-α),interferon-γ (IFN-γ),interleukin-4 (IL-4),and interleukin-10 (IL-10) levels were detected using Luminex method. The mRNA expressions of liver tissue hepcidin gene (HAMP) and membrane iron transporter ( Fpn) were detected using real-time fluorescence PCR method. Results Dried tangerine peel and Chenpi absent Decoction both showed interactive effects in regulating hemoglobin,serum iron,serum ferritin content,improving spleen index,and regulating the mRNA expressions of HAMP,Fpn,as well as IL-1β and IFN-γ (P<0.05). Compared with the model group,dried tangerine peel significantly increased hemoglobin,serum iron content,and Fpn mRNA expression in ZIGI model mice,while decreasing ferritin content,spleen index,HAMP mRNA expression,and the levels of IL-1β,IL-6,TNF-α,and IFN-γ (P<0.05). Chenpi absent Decoction significantly increased serum iron content and Fpn mRNA expression in ZIGI model mice,while reducing spleen index,ferritin content,HAMP mRNA expression,and the levels of IL-1β and IFN-γ、IL-4 (P<0.05). Conclusion The effects of dried tangerine peel on inflammatory factors (IL-6 and TNF-α) and Fpn may play a key role in the improvement effects of Yigong Powder on ACD and iron metabolism.

Objective:To evaluate the efficacy and safety of oliceridine for treatment of moderate to severe pain after surgery with general anesthesia in patients.Methods:The patients with moderate to severe pain (numeric pain rating scale ≥4) after abdominal surgery with general anesthesia from 14 hospitals between July 6, 2021 and November 9, 2021 were included in this study. The patients were assigned to either experiment group or control group using a random number table method. Experiment group received oliceridine, while control group received morphine, and both groups were treated with a loading dose plus patient-controlled analgesia and supplemental doses for 24 h. The primary efficacy endpoint was the drug response rate within 24 h after giving the loading dose. Secondary efficacy endpoints included early (within 1 h after giving the loading dose) drug response rates and use of rescue medication. Safety endpoints encompassed the development of respiratory depression and other adverse reactions during treatment.Results:After randomization, both the full analysis set and safety analysis set comprised 180 cases, with 92 in experiment group and 88 in control group. The per-protocol set included 170 cases, with 86 in experiment group and 84 in control group. There were no statistically significant differences between the two groups in 24-h drug response rates, rescue analgesia rates, respiratory depression, and incidence of other adverse reactions ( P>0.05). The analysis of full analysis set showed that the experiment group had a higher drug response rate at 5-30 min after giving the loading dose compared to control group ( P<0.05). The per-protocol set analysis indicated that experiment group had a higher drug response rate at 5-15 min after giving the loading dose than control group ( P<0.05). Conclusions:When used for treatment of moderate to severe pain after surgery with general anesthesia in patients, oliceridine provides comparable analgesic efficacy to morphine, with a faster onset.

Objective:To establish of a newmethod:for the rapid detection of H5N1-Avian Influenza virus by combining reverse transcription (RT), multiple cross displacement amplification (MCDA) and nanoparticle-based lateral flow biosensor (LFB).Methods:MCDA primers were designed based on gene sequences specific to Hemagglutinin (HA) and Neuraminidase (NA) in H5N1 avian influenza virus. The target genes HA and NA were amplified through reverse transcription and MCDA in one reaction system. Results were displayed by LFB. The assay was named as H5N1-mRT-MCDA-LFB. The reaction conditions of the H5N1-RT-MCDA-LFB method were optimized, and the sensitivity and specificity were also assessed.Results:The H5N1-RT-MCDA-LFB assay could achieve good amplification effect at a constant temperature of 65 ℃ for 40 minutes. The method had a lower limit of detection of 100 fg per reaction with 100-fold higher sensitivity than that of the RT-qPCR (lower limit of detection 10 pg per reaction). The assay was negative in detecting 28 common viruses, mycoplasmas, chlamydias, bacterias and funguses, except for H5N1. In addition, the H5N1-RT-MCDA-LFB method showed better validation in simulated clinical samples with a lower limit of detection at 1×10 2 copies/ml. Conclusion:The H5N1-RT-MCDA-LFB assay is a valuable molecular diagnostic technique for detecting H5N1 avian influenza virus due to its simplicity, rapidity, sensitivity and specificity.

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.

In order to better apply this indicator for the clinical management of patients with chronic HBV infection, recommendations on quantitative detection target regions, detection results, and clinical applications are put forward.

Clinical data of a case with early-onset epileptic encephalopathy admitted in the Department of Neuroendocrinology, Jinan Children′s Hospital in April 2020 were retrospectively analyzed.A 1-month-old male patient was hospitalized for convulsion for 4 days.The child had repeated seizures in the form of tonic and tonic-spasm seizures, accompanied by feeding difficulties, slow weight gain, and overall developmental delay.Electroencephalogram showed multifocal discharge, atypical hypsarrhythmia, and brain magnetic resonance imaging showed delayed myelination.The whole exome sequencing showed compound heterozygous mutation of the WWOX gene.Topiramate, Levetiracetam and Valporate were ineffective to this case.Genetic testing should be performed timely in patients with early-onset epileptic encephalopathy and overall developmental delay to make a clear etiology and prognosis, thus guiding prenatal diagnostics and genetic counseling.

A retrospective analysis was performed on the clinical data of a case of intellectual developmental disorders with dysmorphic facies and behavioral abnormalities admitted in the Department of Neurology and Endocrinology, Children′s Hospital Affiliated to Shandong University in February 2020.The proband was a 3 years and 6 months old boy, who was hospitalized because of " convulsions for more than 1 year" . Physical examination revealed facial deformities.Gesell developmental schedule showed that adaptive and gross motor behavior development was severely retarded, and fine motor, language and personal-social behavior development was moderately retarded.Brain magnetic resonance imaging suggested schizencephaly.Electroencephalogram results indicated extensive discharges mainly in bilateral anterior head areas, and one myoclonic seizure was detected.Gene detection results disclosed the pathogenic variation of the proband, which was a heterozygote mutation (c.2480_2484del) in FBXO11 gene.High-throughput sequencing technology increases the possibility of identifying potential genetic mutations as the cause of disease.Patients with recurrent seizures, multi-malformation and general developmental delays should undergo gene detection in time to clarify the etiology.This technique can guide prenatal diagnosis and genetic counseling.

[Abstract] Objective: To detect the expression of CD39 in head and neck squamous cell carcinoma (HNSCC) tisseus, and to analyze its correlation with patients’clinicopathological features and its prognostic significance. Methods: Tissue specimens and case data of 85 patients with HNSCC underwent surgery at Cancer Hospital of Tianjin from May 2012 to December 2013 were collected for this study. Gene chips were obtained from Oncomine database, and HNSCC cell lines SCC15, UM1, and Cal25 were selected for this study. Online analysis was performed to compare the differential expression of CD39 in buccal mucosa (BM) tissues and HNSCC tissues, Western blotting and Immunohistochemistry (IHC) were used to detect the protein expression of CD39 in HNSCC tissues. Spearman’ s correlation analysis was used to study the correlation between the expressions of CD39 and clinicopathological features of HNSCC patients. Both Kaplan-Meier curve analysis and Log rank test were used to analyze the association between the expression of CD39 in HNSCC tissues and the survival of patients, and Cox risk proportional regression model was used to evaluate the relationship between CD39 expression and the risk of relapse. Results: The transcription level of CD39 was obviously up-regulated in HNSCC tissues than in BM tissues (P<0.01), and CD39 expression was detected in HNSCC cell lines SCC15, UM1 and Cal25. Dexamethasone (DXM) could enhance the expression of CD39 in UM1 cells in dose-dependent manner. CD39 was highly expressed in 53 (62.4%) HNSCC patients, which was positively correlated with preoperative chemotherapy (r=0.234, P<0.05). The recurrence-free survival (RFS) of patients with high CD39 expression was significantly shortened (P<0.05), and high CD39 expression was an independent relapse risk factor (HR=2.328, 95%CI=1.091-4.967; P<0.05) for patients with HNSCC. Conclusion: CD39 is DXM-inducively and constitutively expressed in HNSCC. And over-expression of CD39 is an independent predictor of poor prognosis in HNSCC patients, indicating its important role in the progression of HNSCC.
