Objective·To observe the impact of hip synovitis on the long-term outcomes of free vascularized fibular grafting(FVFG)for osteonecrosis of femoral head(ONFH).Methods·Between October 2001 and December 2013,370 patients diagnosed with ONFH(556 hips)underwent FVFG.Preoperative synovitis was assessed using magnetic resonance imaging(MRI)and quantified with the Hip Inflammation MRI Scoring System(HIMRISS).Patients were divided into no synovitis group,moderate synovitis group,and severe synovitis group.Harris hip scores and the incidence of total hip arthroplasty were collected with an average follow-up duration of 90.5 months(range:5-215 months).Hip survival failure(defined as a Harris hip score lower than 80 at the final follow-up or the occurrence of total hip arthroplasty)was calculated.Multivariable Cox regression analysis was adopted to compare the influence of different degrees of synovial inflammation on long-term prognosis.Results·The proportion of hip survival failure was 28.0％in patients without synovitis and 28.5％in those with moderate synovitis,whereas it was significantly higher(60.4％)in patients with severe synovitis.The results of multivariable Cox regression analysis showed that severe synovitis was an independent risk factor for poor prognosis(HR 2.06,95％CI 1.21-3.53)after adjusting for age,gender,education level,marital status,ONFH type,affected side of ONFH,smoking history,baseline Harris hip score and other hip MRI-based covariates(collapse,bone marrow edema,and degeneration).Conclusion·Severe synovitis in patients with ONFH significantly increases the failure rate of hip preservation after FVFG,and the severity of synovitis should be considered in surgical decision-making.

Objective To investigate the effects of hypoxia on the transcriptional phenotype and ultrastructure of tumor-associated macrophages(TAMs)in glioma.Methods CD14+monocytes were isolated from healthy human peripheral blood samples collected from the Blood Bank of the First Affiliated Hospital of Army Medical University,and the cells were induced to differentiate into TAMs through co-culture with glioma cell-conditioned medium.Hypoxic TAM models were established using varying concentrations of cobalt chloride hexahydrate(CoCl2,50～400 μmol/L)or hypoxic conditions(1%,5%,10%O2)for 48 h,while normoxic TAM models(21%O2)served as controls.RT-qPCR and transcriptome sequencing were employed to analyze transcriptional changes in TAMs under normoxic and hypoxic conditions.Gene set enrichment analysis(GSEA)was applied to compare the differences in angiogenesis,glycolysis and other hypoxia-responsive pathways between the 2 conditions.Transmission electron microscopy(TEM)or immunofluorescence staining was conducted to assess the ultrastructural alterations in cytoskeleton,endoplasmic reticulum(ER),and mitochondria in normoxic and hypoxic TAMs(1%O2).Results Hypoxic TAMs exhibited up-regulated transcription of hypoxia-responsive markers(oxygen transport,glycolysis,pro-angiogenesis),with the effects correlating with hypoxia severity(P<0.05).GSEA revealed significant up-regulation of hypoxia,angiogenesis regulation,glycolysis and gluconeogenesis,and starvation stress pathways,alongside down-regulation of innate immunity,macrophage activation,cytoskeleton,and protein maturation pathways in hypoxic TAMs(P<0.05).TEM and immunofluorescence staining demonstrated obvious ultrastructure changes,including disrupted cytoskeletal organization,shortened rough ER with reduced ribosomes,mitochondrial swelling with cristae damage,and diminished ER-mitochondria contacts in hypoxic TAMs.Conclusion CoCl2 and hypoxia induce a hypoxic transcriptional phenotype in TAMs,which may potentially associated with ultrastructural remodeling of the cytoskeleton,ER,and mitochondria.

The key symptom of Shaoyin syndrome,"only wanting to sleep",aligns with the core symptoms of depression,such as"low mood and loss of interest in daily activities".Additionally,the timing of symptom resolution in Shaoyin syndrome,"from 11 PM to 3 AM",corresponds to the pattern of symptom changes in depression.Therefore,depression can be treated from the perspective of Shaoyin syndrome.The fundamental pathogenesis of depression involves Shaoyin heart-kidney yang deficiency.On one hand,heart-kidney yang deficiency leads to spleen yang deficiency,resulting in a lack of nourishment for the spirit.On the other hand,yang deficiency generates dampness,leading to the stagnation of yang qi and a lack of vitality in the spirit.Mahuang Fuzi Gancao Decoction is the primary formula for treating depression based on Shaoyin syndrome.This formula works by supplementing and warming yang,invigorating the heart and kidneys,warming the spleen to dispel cold,and nourishing the spirit to alleviate depression.Additionally,it promotes lung qi,drains water,and expels pathogens to invigorate the spirit.In clinical application,attention should be paid to the preparation of the herbs,dosage,method of decoction,and administration.The formula can also be adjusted with other classic formulas based on the patients'specific symptoms for optimal effectiveness.

This study aimed to clarify the appropriate disease coding for coronary heart disease(CHD)and procedure coding for coronary stent implantation through an in-depth analysis of the I20-I25 classification for ischemic heart disease in the International Classification of Diseases,Tenth Revision(ICD-10),and the 36.06-36.07 procedure codes for coronary stents in the International Classification of Diseases,Ninth Revision,Clinical Modification(ICD-9-CM-3),2011 revision.Representative cases from a tertiary general hospital were analyzed to illustrate and validate accurate coding practices.Based on coding guidelines and case analyses,a set of correct codes for CHD and coronary stent procedures was compiled.This work provides guidelines for standardizing medical information documentation and provides a reference for medical insurance payment reform in CHD patients undergoing coronary stent implantation.

Objective:To explore the relationship between irritable bowel syndrome (IBS) and premature ejaculation (PE) from 5-HT; To predict the natural drugs with therapeutic effect.Methods:Targets related to IBS and PE were screened in the GeneCards, DisGeNET, TTD, OMIM, DrugBank databases. After removing duplicates, the two disease targets were intersected and imported into STRING platform, and the protein interaction network between IBS and PE targets related to 5-HT receptor was obtained. GO enrichment analysis was carried out on the intersected targets by R language, and Coremine Medical platform was used for predicting natural drugs.Results:5-HT1A, 5-HT1B, 5-HT2A, 5-HT2C and 5-HT3A were the common targets related to 5-HT in IBS and PE. GO function enrichment yielded 250 gene function related information, mainly enriched in serotonin receptor signaling pathways, cell response to dopamine, and response to dopamine. The prediction of natural drugs obtained 14 kinds of Chinese materia medica, including Nelumbinis Semen, Nelumbinis Rhizomatis Nodus, Nelumbinis Receptaculum, Nelumbinis Stamen, Nelumbinis Folium, Nelumbinis Plumula, Ginkgo Semen, and Ginkgo Folium.Conclusions:Abnormal 5-HT levels can affect gastrointestinal motility, ejaculation latency, and glans sensitivity. Elevated central 5-HT levels are a common pathogenesis of IBS and PE. The interaction between receptors such as 5-HT1A and 5-HT3A and 5-HT can regulate gastrointestinal motility and secretion activities, intestinal nervous system, and reduce intestinal hypersensitivity; increasing the sensitivity of the 5-HT1A receptor can reduce the ejaculation threshold and promote ejaculation, while increasing the sensitivity of the 5-HT2C receptor can increase the ejaculation threshold.

Objective:To evaluate the effect of electroacupuncture preconditioning on emergence agitation in the patients undergoing total laparoscopic hysterectomy.Methods:This was a randomized controlled trial. Ninety American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ patients, aged 40-60 yr, with a body mass index of 50-70 kg, scheduled for elective total laparoscopic hysterectomy, were divided into control group (C group) and electroacupuncture preconditioning group (E group) using a random number table method, with 45 patients in each group. At 30 min before anesthesia induction, Zusanli and Neiguan acupoints were stimulated for 30 min with disperse-dense waves at a frequency of 2 Hz/100 Hz, an intensity of 3 mA, in group E. Group C did not receive electroacupuncture treatment. The occurrence of emergence agitation, usage of vasoactive drugs and rescue analgesia were recorded in two groups. Peripheral venous blood samples from the upper extremity were obtained before electroacupuncture stimulation (T 0) and at 2 h after operation (T 1) for determination of the plasma concentrations of C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α) and interleukin-10 (IL-10) by enzyme-linked immunosorbent assay. Results:The plasma CRP and TNF-α concentrations in group C and plasma IL-10 concentrations in group E were significantly higher at T 1 than at T 0 ( P<0.05). Compared with group C, the usage rate of vasoactive drugs, rate of rescue analgesia, and incidence of emergence agitation were significantly decreased, and the plasma concentrations of CRP and TNF-α were decreased and the plasma IL-10 concentrations were increased at T 1 in group E ( P<0.05). Conclusions:Electroacupuncture preconditioning can decrease the occurrence of emergence agitation in the patients undergoing total laparoscopic hysterectomy, which may be related to inhibiting inflammatory responses.

Objective:To evaluate the effect of electroacupuncture preconditioning on cellular immune function in the patients undergoing thyroid surgery.Methods:Sixty-six patients of either sex, aged 30-55 yr, with body mass index of 18.5-23.9 kg/m 2, of American Society of Anesthesiologists Physical Status classification ⅠorⅡ, were selected and divided into electroacupuncture preconditioning group (group D) and control group (group C) by a random number table method, with 33 cases in each group. Patients in both groups received combined intravenous-inhalational anesthesia. Before anesthesia induction, both Hegu and Neiguan acupoints were stimulated for 30 min using a continuous wave at a frequency of 2/100 Hz, and the stimulation intensity was subjected to patient tolerance in group D. Group C received sham electroacupuncture for 30 min without stimulation. Venous blood samples were collected at 30 min before anesthesia induction (T 0) and 12, 24 and 48 h after anesthesia (T 1-3). The percentages of T lymphocyte subsets (CD3 +, CD4 +, CD8 +, CD4 + /CD8 + ) and natural killer cells and concentrations of interleukin-6 and tumor necrosis factor-alpha in the serum were measured by flow cytometry. Results:Compared with group C, the percentage of CD3 +, CD4 + and natural killer cells and ratio of CD4 + /CD8 + were significantly increased at T 1, 2, and the concentrations of interleukin-6 and tumor necrosis factor-alpha in the serum were decreased at T 1-3 in group D ( P<0.05). Conclusions:Electroacupuncture preconditioning can improve cellular immune function in the patients undergoing thyroid surgery.
