Mechanism and prevention of liver failure complicated by acute pancreatitis / 临床肝胆病杂志

Liver failure often has rapid progression， multiple complications， and dangerous conditions. Acute pancreatitis is a common comorbidity during the progression of liver failure， and since acute pancreatitis has extremely similar clinical symptoms and signs to liver failure complicated by spontaneous peritonitis， it is often neglected in clinical practice. This article elaborates on the mechanisms of liver failure complicated by acute pancreatitis from the five aspects of inflammatory response， duodenal papillary dysfunction， gut microbiota dysbiosis， oxidative stress， and microcirculatory disturbance and proposes corresponding preventive measures based on these mechanisms.

Clinical phenotypic and genotypic analysis of 5 pediatric patients with β-ketothiolase deficiency / 中华儿科杂志

Objective: To summarize the clinical and genetic characteristics of children with β-ketothiolase deficiency (BKTD). Methods: The clinical characteristics, biochemical, markers detected by tandem mass spectrometry (MS/MS) and gas chromatography-mass spectrometry (GC/MS), as well as the variants in ACAT1 gene among 5 children with BKTD in Children's Hospital of Chongqing Medical University between October 2018 and December 2022 were retrospectively analyzed. Results: The onset age of the disease in 5 patients (4 males and 1 female) ranged from 9.7 to 28.0 months. During the acute phase, severe metabolic acidosis was observed with a pH of 6.9-7.1, as well as hypoglycaemia (2.3-3.4 mmol/L) and positive urinary ketone bodies (+-++++). Blood levels of methylcrotonyl carnitine, methylmalonyl carnitine and malonyl carnitine were 0.03-0.42, 0.34-1.43 and 0.83-3.53 μmol/L respectively and were significantly elevated. Urinary 2-methyl-3-hydroxybutyric acid was 22-202 and 3-hydroxybutyric acid was 4-6 066, both were higher than the normal levels. Methylcrotonylglycine was mild elevated (0-29). The metabolites detected by MS/MS and GC/MS were significantly reduced after treatment. Analysis of ACAT1 gene mutation was performed in 5 children. Most variants were missense (8/9). Four previously unreported variants were identified: c.678G>T (p.Trp226Cys), c.302A>G (p.Gln101Arg), c.627_629dupTGA (p.Asn209_Glu210insAsp) and c.316C>T (p.Gln106Ter), the first 2 variants were predicted to be damaging by SIFT, PolyPhen-2 and Mutation Taster software. c.316C>T (p.Gln106Ter) is a nonsense variant. Conclusions: β-ketothiolase deficiency is relatively rare, lacks specific clinical manifestations, however severe metabolic acidosis, hypoglycemia, and ketosis during the acute onset were consistent findings. Missense mutations in the ACAT1 gene are common genetic causes of β-ketothiolase deficiency.

Xinjia Congrong Tusizi Decoction Regulates Ferroptosis of Granulosa Cells in Rat Model of Premature Ovarian Insufficiency via p53/Nrf2 Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo investigate the effects of Xinjia Congrong Tusizi decoction （XJCTD） on ovarian functions in the rat model of premature ovarian insufficiency （POI） and decipher the mechanism of regulating the tumor suppressor protein （p53）/nuclear factor E2-related factor 2 （Nrf2） pathway to attenuate granulosa cell ferroptosis. MethodForty-eight SPF-grade female SD rats were randomized into control， model， low-， medium-， and high-dose （1.1， 2.2， 4.4 g·kg-1） XJCTD， and Western medicine （coenzyme Q10， 0.002 7 g·kg-1） groups， with eight rats in each group. The rat model of POI was established by gavage of triptolide （TP）， and after successful modeling， each group was administrated with the corresponding drugs by gavage for 14 d. The body weight and ovarian weight of each rat were weighed and the ovarian index was calculated. The morphology of the ovarian tissue was observed by hematoxylin-eosin staining， and the proportions of growing follicles and atretic follicles were calculated. The serum levels of anti-Müllerian hormone （AMM）， estradiol （E2）， and follicle-stimulating hormone （FSH） were measured by enzyme-linked immunosorbent assay （ELISA）. The DCFH-DA fluorescent probe was used to measure the reactive oxygen species （ROS） content in granulosa cells. The content of cellular Ferrous ion （Fe2+）， lipid peroxide （LPO）， malondialdehyde （MDA）， glutathione （GSH）， and superoxide dismutase （SOD） was detected by colorimetry. The expression of the tumor suppressor protein p53，Nrf2， solute carrier family 7 member 11 （SLC7A11）， and glutathione peroxidase 4 （GPX4） was determined by immunohistochemistry and Western blot. ResultCompared with the control group， the model group showed decreased ovarian weight， body weight， and ovarian index （P<0.01）， reduced ovarian tissue volume and proportion of growing follicles （P<0.01）， increased proportion of atretic follicles （P<0.01）， lowered AMH and E2 levels and elevated FSH level in the serum （P<0.01）， and elevated levels of Fe2+， ROS， LPO， and MDA （P<0.01） and lowered levels of GSH and SOD in granulosa cells （P<0.01）. Moreover， the modeling up-regulated the expression of p53 （P<0.01） and down-regulated the expression of Nrf2， SLC7A11， and GPX4 （P<0.05， P<0.01） in the ovarian tissue. Compared with the model group， XJCTD increased the body weight， ovarian weight， and ovarian index （P<0.01）， alleviated the pathological changes in the ovarian tissue， increased the proportion of growing follicles （P<0.01）， decreased the proportion of atretic follicles （P<0.01）， and reduced the content of ROS in granulosa cells （P<0.05， P<0.01）. In addition， medium- and high-dose XJCTD lowered the FSH level （P<0.01） and raised E2 and AMH levels （P<0.01） in the serum， reduced the Fe2+ content （P<0.05， P<0.01）， and increased the SOD content （P<0.01） in granulosa cells. High-dose XJCTD reduced the LPO and MDA content （P<0.01） and increased the SOD content （P<0.01） in the granulosa cells， down-regulated the expression of p53 （P<0.05）， and up-regulated the expression of Nrf2， SLC7A11， and GPX4 in the ovarian tissue （P<0.05， P<0.01）. ConclusionXJCTD may protect the ovarian function in the rat model of POI by regulating the p53/Nrf2 signaling pathway to attenuate the ferroptosis of ovarian granulosa cells.

A novel predictor of unsustained return of spontaneous circulation in cardiac arrest patients through a combination of capnography and pulse oximetry: a multicenter observational study / 世界急诊医学杂志（英文）

@#BACKGROUND: Unsustained return of spontaneous circulation (ROSC) is a critical barrier to survival in cardiac arrest patients. This study examined whether end-tidal carbon dioxide (ETCO2) and pulse oximetry photoplethysmogram (POP) parameters can be used to identify unsustained ROSC. METHODS: We conducted a multicenter observational prospective cohort study of consecutive patients with cardiac arrest from 2013 to 2014. Patients’ general information, ETCO2, and POP parameters were collected and statistically analyzed. RESULTS: The included 105 ROSC episodes (from 80 cardiac arrest patients) comprised 51 sustained ROSC episodes and 54 unsustained ROSC episodes. The 24-hour survival rate was significantly higher in the sustained ROSC group than in the unsustained ROSC group (29.2% vs. 9.4%, P<0.05). The logistic regression analysis showed that the difference between after and before ROSC in ETCO2 (ΔETCO2) and the difference between after and before ROCS in area under the curve of POP (ΔAUCp) were independently associated with sustained ROSC (odds ratio [OR]=0.931, 95% confidence interval [95% CI] 0.881-0.984, P=0.011 and OR=0.998, 95% CI 0.997-0.999, P<0.001). The area under the receiver operating characteristic curve of ΔETCO2, ΔAUCp, and the combination of both to predict unsustained ROSC were 0.752 (95% CI 0.660-0.844), 0.883 (95% CI 0.818-0.948), and 0.902 (95% CI 0.842-0.962), respectively. CONCLUSION: Patients with unsustained ROSC have a poor prognosis. The combination of ΔETCO2 and ΔAUCp showed significant predictive value for unsustained ROSC.

Cinobufagin Combined with Thalidomide/Dexamethasone Regimen in the Treatment of Patients with Newly Diagnosed Multiple Myeloma of Phlegm and Stasis Obstruction： A Retrospective Study / 中医杂志

ObjectiveTo investigate the efficacy and safety of cinobufagin tablets combined with thalidomide/dexamethasone （TD） regimen in the treatment of newly diagnosed multiple myeloma （NDMM） with phlegm and stasis obstruction. MethodsThe clinical data of 50 patients with NDMM of phlegm and stasis obstruction who were hospitalized at the Jiangsu Province Hospital of Chinese Medicine from June 1st， 2015 to July 31th， 2019 were retrospectively analyzed， and they were divided into a control group （bortezomib/dexamethasone-containing regimen， 27 cases） and an observation group （cinobufagin tablets combined with TD regimen， 23 cases）. The clinical efficacy and safety were compared between the two groups after two or three courses of treatment. The primary outcomes were clinical remission rate including overall response rate and deep remission rate， one-year and two-year overall survival rate， and adverse effects. The secondary outcomes were the proportion of plasma cells in bone marrow， hemoglobin， β2-microglobulin， lactate dehydrogenase， serum creatinine， blood urea nitrogen， bone pain score， and KPS functional status score （KPS score） before and after treatment. ResultsIn terms of clinical efficacy， there was no statistically significant difference （P＞0.05） in the overall response rate ［the observation group 69.57%（16/23） vs the control group 70.37% （19/27）］ and deep remission rate ［the observation group 56.52% （13/23） vs the control group 55.56% （15/27）］ between groups after the treatment. The one-year overall survival rates of the observation group and the control group were 90.9% and 92.4%， and the two-year overall survival rates were 81.8% and 80.9% respectively， with no statistically significant differences between groups （P＞0.05）. During the treatment， no renal function injury occurred in both groups. The incidence of peripheral nerve injury in the observation group was 8.70%， which was lower than 48.15% in the control group （P＜0.01）. After the treatment， the proportion of myeloma plasma cells， β2-microglobulin， serum creatinine level， and bone pain score decreased， while the hemoglobin level and KPS score increased in both groups （P＜0.05 or P＜0.01）. Compared between groups after treatment， the bone pain score of the observation group was lower than that of the control group， while the KPS score was higher than that of the control group （P＜0.05）. ConclusionThe clinical efficacy of cinobufagin tablets combined with TD in the treatment of NDMM is equivalent to bortezomib/dexamethasone-containing regimen， but the former is more helpful in relieving the pain and improving the quality of life， and has better safety.

Traditional Chinese Medicine Against Fibrotic Diseases： A Review / 中国实验方剂学杂志

Fibrosis can occur in diverse tissue and organs and is the common outcome as multiple chronic diseases progress. It is characterized by over-activation of fibroblasts and excessive deposition of extracellular matrix. Targeting transforming growth factor-β （TGF-β）， a classical signaling molecule in fibrosis， is currently a routine strategy for drug therapy of this disease. The use of traditional Chinese medicine （TCM） in the treatment of fibrotic diseases has been supported by mature theories. The theories emphasize that the internally-accumulated pathogens and mixed deficiency-excess underlie the shared pathology of fibrotic diseases. Qi stagnation， blood stasis， phlegm turbidity， and mass accumulation are key pathological factors. "Yin suppression by Yang" is the core thought for treatment with TCM of the disease. Pharmacological investigations reveal the scientific nature of TCM in treating fibrotic diseases， namely multilevelled and multitargeted. In other words， it refers to networked regulation of signaling activities of fibrosis-related molecules such as TGF-β/Drosophila protein homolog （Smad）， phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）， Hedgehog， Wnt/β-catenin， and inflammatory cytokines， so as to inhibit fibroblast function and provide a promising insight into novel anti-fibrotic drug. This paper summarized the conventional understanding of fibrotic disease treatment with TCM and its mechanism of action by reviewing ancient literature and modern research reports， which offers an idea for follow-up research in this field.

Malignant gastrointestinal neuroectodermal tumor: a clinicopathological analysis of three cases / 中华病理学杂志

Objective: To investigate the clinicopathological characteristics of malignant gastrointestinal neuroectodermal tumors (GNET), and to describe their clinical, histological, immunophenotypic, ultrastructural, and molecular features, diagnosis and differential diagnosis. Methods: Three cases of malignant GNET were collected at Xijing Hospital of the Fourth Military Medical University, from 2013 to 2022. All patients underwent surgical resection of the tumor. Histological, immunohistochemical (IHC), ultrastructural and molecular genetic analyses were performed, and the patients were followed up for six months, three years and five years. Results: There were two males and one female patients. The tumors were located in the ileum, descending colon, and rectum, respectively. Grossly, the tumors were solid, firm, and poorly circumscribed, measured in size from 2 to 4 cm in greatest dimension, and had a greyish-white cut surface. These tumors were histologically characterized by a sheet-like or nested population of oval to spindled cells or epithelioid cells with weakly eosinophilic or clear cytoplasm, small nucleoli and scattered mitoses. Electron microscopy showed neuroendocrine differentiation, and no evidence of melanogenesis. IHC staining showed that the tumor cells were diffusely positive for S-100 protein, SOX10, CD56, synaptophysin and vimentin. They were negative for melanocytic markers, HMB45 and Melan A. All three cases showed split EWSR1 signals consistent with a chromosomal translocation involving EWSR1. Next-generation sequencing in one case confirmed the presence of EWSR1-ATF1 fusion. These patients were followed up for 6 months, 3 years and 5 years, respectively, and all of them developed possible lung or liver metastases, and one of them died of multiple pulmonary metastases. Conclusion: Malignant GNET has distinctive morphological, IHC, and molecular genetic features and it should be differentiated from other malignancies of the gastrointestinal tract, especially clear cell sarcoma and melanoma.

Gastrointestinal ALK-positive anaplastic large cell lymphoma: a clinicopathological analysis of five cases / 中华病理学杂志

Objective: To investigate the clinicpathological characteristics of ALK-positive anaplastic large cell lymphoma (ALCL) of the gastrointestinal tract, and to discuss its diagnosis and differential diagnosis. Methods: Five cases of gastrointestinal ALK-positive ALCL diagnosed and treated in Xijing Hospital of the Fourth Military Medical University, between 2011 and 2019 were collected. There were three male and two female patients, aged 5-42 years (mean 25 years). These patients clinically presented with fever and night sweats, weight loss, abdominal pain, abdominal mass, ulcers, bleeding, or intestinal obstruction, and underwent surgical resection of the tumors or endoscopic biopsy. The clinical manifestations, auxiliary examinations, histopathological characteristics, immunophenotypes and genetic alterations were analyzed. Results: In this cohort, one case was common type, two cases were monomorphic variant of common type, and two cases were small cell variant. The tumor cells in all cases expressed ALK, CD30, and one or more T lymphocyte markers, while all the markers of B lymphocyte and plasmacyte were negative. Clonality analysis showed that two cases had clonal T cell receptor (TCR) and immunoglobulin (Ig) gene rearrangement, one case had no clonal TCR but Ig gene rearrangement, and one case had no clonal TCR and Ig gene rearrangements. During the 4 to 67 months' follow-up, two patients died of the disease, two were alive with free of disease and one had a relapse. Conclusions: ALK-positive ALCL of the gastrointestinal tract is extremely rare, and has poor prognosis. Lymphoma originating from this site with CD30 and ALK-positive phenotypes may be considered to be ALCL; however differentiation from other tumors that had anaplastic features, expressed CD30 and or ALK, in particular, ALK positive large B-cell lymphoma is necessary.

Relationships between hypertensive disorders in pregnancy and obstructive sleep apnea syndrome / 中华妇产科杂志

Objective: To investigate the impact of obstructive sleep apnea syndrome (OSAS) on pregnancy outcomes, especially the relationship between OSAS and hypertensive disorders in pregnancy (HDP). Methods: A total of 228 pregnant women with high risk of OSAS who underwent sleep monitoring during pregnancy in Peking University People's Hospital from January 2021 to April 2022 were collected by reviewing their medical records for retrospective analysis. According to the diagnosis of OSAS, the pregnant women were divided into OSAS group (105 cases) and non-OSAS group (123 cases). The non-parametric Mann-Whitney U test, χ2 test or Fisher's exact test were used to compare the general data and maternal and fetal outcomes between the two groups, and the occurrence of each type of HDP was further compared. Results: (1) Compared with the non-OSAS group, the median pre-pregnancy body mass index (23.6 vs 27.6 kg/m2) and the proportion of snoring [28.9% (33/114) vs 59.2% (61/103)] in the OSAS group were higher, and the differences were both statistically significant (both P<0.001). (2) The incidence of HDP [67.6% (71/105) vs 39.0% (48/123)] and gestational diabetes mellitus [GDM; 40.0% (42/105) vs 26.8% (33/123)] of pregnant women in the OSAS group were higher than those in the non-OSAS group, and the median delivery week was shorter than that in the non-OSAS group (38.4 vs 39.0 weeks). The differences were all statistically significant (all P<0.05). Between-group differences for the delivery way, postpartum hemorrhage, the rate of intensive care unit admission, preterm birth, small for gestational age infants, neonatal asphyxia, the rate of neonatal intensive care unit admission, newborn birth weight and the proportion of umbilical artery blood pH<7.00 were not statistically significant (all P>0.05). (3) Compared with the non-OSAS group, the incidence of chronic hypertension [11.4% (14/123) vs 22.9% (24/105)] and chronic hypertension with superimposed pre-eclampsia [11.4% (14/123) vs 30.5% (32/105)] were higher in the OSAS group, and the differences were both statistically significant (both P<0.01). Conclusion: OSAS is related to HDP (especially chronic hypertension and chronic hypertension with superimposed pre-eclampsia) and GDM, which could provide a practical basis for the screening, diagnosis and treatment of OSAS in pregnant women at high risk.

Clinical study of mature B-cell lymphoma in 11 children with chromosome 11 long-arm abnormalities / 中华血液学杂志

Objective: To explore the clinical, pathological, diagnostic, treatment, and prognostic features of children with mature B-cell lymphoma (MBCL) . Methods: This retrospective study included pediatric patients with MBCL with chromosome 11 long-arm abnormalities who were diagnosed and treated at our hospital from December 2018 to February 2023. Results: Among the 11 pediatric patients with MBCL, nine were male and two were female, with a median age of 9 (2-13) years and a median disease course of 1.8 (0.5-24) months. The clinical manifestations were cervical lymph node enlargement in four patients, nasal congestion and snoring in four patients, abdominal pain in two patients, and difficulty breathing in one patient. There were seven cases of Burkitt's lymphoma, two of follicular lymphoma, and two of advanced B-cell lymphoma according to the pathological morphology examination. No patients had central nervous system or bone marrow involvement, and no extensive metastasis was observed on B-ultrasound or positron emission tomography-computed tomography (PET/CT). One patient had a huge tumor lesion. The Revised International Pediatric Non-Hodgkin Lymphoma Staging System classified four patients as stage Ⅱ, five as stage Ⅲ, and two as stage Ⅳ. 11q probe detection showed five cases of 11q gain, three of 11q loss, and three of both gain and loss. FISH showed positive MYC expression in three patients, including eight with advanced B-cell lymphoma with 11q abnormalities and three with Burkitt's lymphoma with 11q abnormalities. According to the 2019 edition of the National Health Commission's diagnostic and treatment guidelines for invasive MBCL in children, one patient was classified as Group A, two as Group B, and eight as Group C. Early evaluation of the efficacy showed complete remission. After mid-term evaluation, the intensity of chemotherapy was reduced in Group B and Group C. Among two cases of chemotherapy, the remaining nine cases had a median follow-up of 32 (6-45) months, and none had event-related survival. Conclusion: The incidence of MBCL with 11q abnormalities in children is low, clinical symptoms are mild, and progression is slow. The absence of MYC, BCL2, BCL6 rearrangements, C-MYC negative and 11q abnormalities on FISH is an important diagnostic indicator, and reducing the intensity of chemotherapy can improve prognosis.

KCTD4 interacts with CLIC1 to disrupt calcium homeostasis and promote metastasis in esophageal cancer

Increasing evidences suggest the important role of calcium homeostasis in hallmarks of cancer, but its function and regulatory network in metastasis remain unclear. A comprehensive investigation of key regulators in cancer metastasis is urgently needed. Transcriptome sequencing (RNA-seq) of primary esophageal squamous cell carcinoma (ESCC) and matched metastatic tissues and a series of gain/loss-of-function experiments identified potassium channel tetramerization domain containing 4 (KCTD4) as a driver of cancer metastasis. KCTD4 expression was found upregulated in metastatic ESCC. High KCTD4 expression is associated with poor prognosis in patients with ESCC and contributes to cancer metastasis in vitro and in vivo. Mechanistically, KCTD4 binds to CLIC1 and disrupts its dimerization, thus increasing intracellular Ca2+ level to enhance NFATc1-dependent fibronectin transcription. KCTD4-induced fibronectin secretion activates fibroblasts in a paracrine manner, which in turn promotes cancer cell invasion via MMP24 signaling as positive feedback. Furthermore, a lead compound K279-0738 significantly suppresses cancer metastasis by targeting the KCTD4‒CLIC1 interaction, providing a potential therapeutic strategy. Taken together, our study not only uncovers KCTD4 as a regulator of calcium homeostasis, but also reveals KCTD4/CLIC1-Ca2+-NFATc1-fibronectin signaling as a novel mechanism of cancer metastasis. These findings validate KCTD4 as a potential prognostic biomarker and therapeutic target for ESCC.

Analysis of emotional and behavioral problems and related factors in children with diurnal urinary incontinence / 现代泌尿外科杂志

【Objective】 To investigate the current situation and related factors of emotional and behavioral problems in children with diurnal urinary incontinence (DUI), in order to provide reference for clinical treatment and psychological intervention. 【Methods】 During Sep.2019 and Mar.2020, a survey was conducted in six primary schools in a county of Henan Province using the method of cluster sampling. The survey included general data and current DUI and urination-related problems, Strengths and Difficulties Scale (SDQ), and Pittsburgh Sleep Quality Index (PSQI). 【Results】 Of the 4 500 questionnaires distributed, 4 120 were collected, and 3 912 were qualified for statistical analysis. The overall prevalence of DUI was 3.6%. The detection rate of abnormal emotion and behavior in the DUI group was 48.2%, which was significantly higher than that in the non-DUI group (12.6%) (P<0.05). The scores of emotional symptoms, conduct problems, hyperactivity, peer communication problems and SDQ were significantly higher in the DUI group than in the control group (P<0.05). The results of multivariate analysis showed that gender, academic achievement, DUI times, caregivers, caregivers’ education level, family education style and sleep disorder were influencing factors of emotional and behavioral problems in DUI children (P<0.05). The total score of SDQ was positively correlated with the total score of PSQI (P<0.05). 【Conclusion】 The detection rate of emotional and behavioral abnormalities is high in DUI children, which is related to gender, academic achievement, DUI times, caregivers, education level of caregivers, family education style and sleep disorders.

Analysis of related factors of emotional and behavioral abnormalities in children with overactivity of bladder / 现代泌尿外科杂志

【Objective】 To analyze the related factors of emotional and behavioral abnormalities in children with overactive bladder (OAB). 【Methods】 OAB children (aged 6 to 16 years) in a survey of 5 032 children from a county in Henan Province during Sep.2022 and Dec.2022 were identified and surveyed with Overactive Bladder Symptom Score (OABSS), Strength and Difficulties Questionnaire (SDQ) and Pediatric Sleep Questionnaire (PSQ). According to the SDQ score, they were divided into abnormal group (SDQ≥20) and normal group. 【Results】 There were 35.7%(137/385) cases in the abnormal group and 64.3% (248/385) in the normal group. Gender, education level of caregivers, body mass index (BMI), age, constipation, enuresis and severity of OAB were significantly associated with emotional and behavioral abnormalities (P<0.05). Children in the abnormal group showed significant differences in emotional symptoms, conduct problems, hyperactivity symptoms, peer interaction and sleep (P<0.001). Multivariate regression analysis revealed significant differences in gender, educational level of caregi-vers, BMI, age, constipation, enuresis, severity of OAB and PSQI between the two groups (P<0.05). 【Conclusion】 The prevalence of emotional and behavioral abnormalities is high in children with OAB, which is related to female gender, high BMI, puberty, constipation, enuresis and severity of OAB.

【Objective】 To investigate the possibility of using voiding diary (VD) to predict desmopressin diacetate arginine vasopressin (DDAVP) and enuresis alarm (EA) in the treatment of primary monosymptomatic nocturnal enuresis (PMNE). 【Methods】 A total of 100 children (aged 6 to 14 years) with PMNE treated during Jan.2018 and Oct.2022 were involved. Bladder type was classified with two-week VD. Pseudo-randomization was performed using the Danish REDCap system to group patients into the randomized group and VD group. All patients were treated for 8 weeks. 【Results】 A total of 82 cases met the inclusive criteria. The effective rate was 82.50% (33/40) and 59.52% (25/42) in the VD and randomized groups, respectively, with significant difference (χ2=5.224, P=0.022). In the randomized group, if VD was not considered, the effective rate in the DDAVP and EA subgroups was 81.82% (18/22) and 25.00% (5/20), respectively, with significant difference (χ2=13.625, P=0.000). 【Conclusion】 VD can predict the therapeutic effects of PMNE. It is necessary to record VD for two weeks before selecting appropriate treatment methods. For patients who choose treatment without reference to VD, DDAVP shows better response than EA, but the recurrence rate after discontinuation of treatment requires further follow-up.

Clinical features of bone mass loss in liver cirrhosis and its association with sarcopenia / 临床肝胆病杂志

ObjectiveTo investigate the influence of sarcopenia on bone mass loss， the risk factors for bone mass loss in liver cirrhosis， and the correlation between body composition and bone mineral density （BMD） by comparing the clinical features of bone mass loss in patients with liver cirrhosis. MethodsA total of 92 patients who were hospitalized and diagnosed with liver cirrhosis in Department of Gastroenterology， The Second Affiliated Hospital of Kunming Medical University， from April to December of 2022 were enrolled， and based on the results of dual-energy X-ray absorptiometry， they were divided into bone mass loss group （osteopenia/osteoporosis） with 57 patients and normal bone mass group with 35 patients. The two groups were compared in terms of general data， laboratory examination， imaging data， and body composition analysis. The independent samples t-test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the continuity correction chi-square test was used for comparison of categorical data between two groups； Pearson correlation analysis and Spearman correlation analysis were used to investigate correlation； a binary logistic regression analysis was used to investigate the risk factors for bone mass loss in liver cirrhosis. ResultsCompared with the normal bone mass group， the bone mass loss group had significantly higher age （t=-3.597， P<0.05）， proportion of female patients （χ2=8.393， P<0.05）， N-terminal middle molecular fragment of osteocalcin （N-MID） （Z=-3.068， P<0.05）， β isomer of C-terminal telopeptide of type I collagen （β-CTX） （t=-2.784， P<0.05）， and proportion of patients with sarcopenia （χ2=13.884， P<0.05） and significantly lower calcitonin （CT） （Z=-2.340， P<0.05） and L3 skeletal muscle index （L3-SMI） （t=4.621， P<0.05）. Compared with the normal bone mass group， the bone mass loss group had significantly lower total muscle mass （Z=-2.952， P<0.05）， right upper limb muscle mass （Z=-2.929， P<0.05）， left upper limb muscle mass （Z=-2.680， P<0.05）， right lower limb muscle mass （Z=-3.366， P<0.05）， left lower limb muscle mass （Z=-3.374， P<0.05）， presumed bone mass （t=2.842， P<0.05）， body water mass （Z=-2.779， P<0.05）， basal metabolic rate （BMR） （Z=-3.153， P<0.05）， and BMD of L1— L4 and femoral neck （t=9.789， t=10.280， t=10.832， Z=-7.298， t=8.945， all P<0.05）. Total muscle mass， muscle mass of trunk and limbs， presumed bone mass， BMR， and body water mass in body component analysis were positively correlated with L1 — L4 BMD and femoral neck BMD （all P<0.05）， and fat mass was positively correlated with L1 — L4 BMD （all P<0.05）. Sarcopenia （odds ratio ［OR］=8.737， 95% confidence interval ［CI］： 2.237 — 34.129， P=0.002）， age （OR=1.094， 95%CI： 1.019 — 1.175， P=0.013）， and N-MID （OR=1.095， 95%CI： 1.019 — 1.176， P=0.014） were independent risk factors for bone mass loss in patients with liver cirrhosis. ConclusionOld age， female sex， sarcopenia， elevated N-MID， elevated β-CTX， reduction in CT， low muscle mass， low presumed bone mass， low BMR， and low body water mass are the features of bone mass loss in patients with liver cirrhosis， and sarcopenia， age， and N-MID are independent risk factors for bone mass loss in patients with liver cirrhosis. Detailed assessment of body composition changes can help to identify abnormal BMD in patients with liver cirrhosis.
