Clinical Efficacy of Modified Yigongsan Combined with Multi-enzyme Tablets and Bifidobacterium Triple Live Powder in Treatment of Infantile Anorexia with Spleen-Stomach Qi Deficiency Syndrome / 中国实验方剂学杂志

ObjectiveTo observe the clinical efficacy of modified Yigongsan combined with multi-enzyme tablets and bifidobacterium triple live powder on infantile anorexia with spleen-stomach Qi deficiency syndrome. MethodA total of 112 infantile patients anorexia with spleen-stomach Qi deficiency syndrome treated at Hebei Provincial Hospital of Traditional Chinese Medicine from January 2022 to June 2023 were enrolled and divided into a control group and an observation group， with 56 cases in each group， according to a random number table. Children in the control group were treated with multi-enzyme tablets and Bifidobacterium triple live powder， while those in the observation group were treated with modified Yigongsan in addition to the treatment in the control group. During the study， one case dropped out in the control group and two cases dropped out in the observation group. The clinical efficacy of the two groups of children was compared， including changes in traditional Chinese medicine （TCM） syndrome scores （main symptoms， secondary symptoms， tongue， and pulse）， time to restore normal food intake， and increase in body weight. Changes in calcium， iron， zinc levels， hemoglobin， and albumin levels before and after treatment， as well as changes in gastrointestinal hormones such as gastrin and motilin， vasoactive intestinal peptide， somatostatin， neuropeptide Y， orexin， and leptin， were observed. The occurrence of adverse reactions in the two groups of children during the study was also recorded. ResultThe total effective rate of children in the control group after treatment was 85.19% （46/54）， while that in the observation group was 98.15% （53/54） （χ2 =5.939， P<0.05）. Compared with the control group， the time for food intake to return to normal in the observation group was shorter， and the increase in body weight was greater （P<0.05）. Compared with the results before treatment， the TCM syndrome scores （main symptoms， secondary symptoms， tongue， and pulse） in both groups of children significantly decreased， while the levels of calcium， iron， zinc， hemoglobin， albumin， gastrin， motilin， neuropeptide Y， and orexin increased， and the levels of vasoactive intestinal peptide， somatostatin， and leptin decreased （P< 0.01）. Compared with the control group after treatment， the improvement in the above indicators in the observation group was more significant （P<0.01）. The incidence of adverse reactions in the two groups of children during the treatment period was similar， and the difference was not statistically significant. ConclusionModified Yigongsan combined with multi-enzyme tablets and Bifidobacterium triple live powder is highly effective in treating infantile anorexia （spleen-stomach Qi deficiency syndrome）. After treatment， symptoms of the children were improved，appetite and food intake increased， gastrointestinal function was improved， body weight increased， and adverse reactions were few， indicating that the treatment was safe and reliable.

Clinical value of serum TgAb and TPOAb in diagnosis and treatment of papillary thyroid microcarcinoma / 重庆医学

Objective To investigate the clinical value of thyroid globulin antibody(TgAb)and thyroid peroxidase antibody(TPOAb)in the diagnosis and treatment of papillary thyroid microcarcinoma(PTMC).Methods A total of 346 patients with thyroid nodules who underwent surgical treatment in the hospital from August 2012 to October 2021 were selected as the research objects.According to the postoperative pathologi-cal results,the patients were divided into the benign nodule group,PTMC group and non-micro papillary thy-roid carcinoma(PTC)group.The general data of the patients and thyroid function indexes[free triiodothyro-nine(FT3),free tetraiodothyronine(FT4),thyroid stimulating hormone(TSH),TgAb and TPOAb]before and after operation were collected,the tumor recurrence or lymph node metastasis after operation were ob-served,and the relationship between serum TgAb and TPOAb and the risk and prognosis of PTMC was ana-lyzed.Results The positivity rate of TgAb in the PTMC and non-micro PTC groups was significantly higher than that in the benign nodule group(P<0.05).The TPOAb positivity rate was not significantly different among the three groups(P>0.05).Only the TSH level in the PTMC group was higher than that in the non-micro PTC group(P<0.05).Multivariate logistic analysis showed that younger age,higher TSH and positive TgAb were independent risk factors for PTMC and non-micro PTC(P<0.05).However,the risk of PTC didn't increase with increasing TgAb titres.The positivity rate of TgAb in the PTMC and non-micro PTC groups didn't change significantly within one month after operation,but decreased in one year after operation(P<0.05).The TPOAb positivity rate decreased after operation,but the difference was not statistically sig-nificant(P>0.05).In the PTMC group,four cases had tumor recurrence or lymph node metastasis,and the TgAb level increased by 88.4%,49.5%,5.7%and 84.0%respectively when the tumor recurred or metasta-sized.Among them,the TPOAb level increased by 51.6%,30.0%and 2.9%respectively in three cases and decreased by 53.9%in one case.In the PTMC group,there were 11 patients with cervical lymph node enlarge-ment,and there was no statistical difference in TgAb and TPOAb levels when the condition changed(P>0.05).Conclusion TgAb is a risk factor for PTMC,and can be followed up regularly during the diagnosis and treatment of PTMC.The specificity of TPOAb is not as good as that of TgAb,and appropriate follow-up can be chosen during the course of the disease.

Identification of Dalbergia odorifera and Its Counterfeits by HS-GC-MS / 中国实验方剂学杂志

ObjectiveTo screen the differential markers by analyzing volatile components in Dalbergia odorifera and its counterfeits， in order to provide reference for authentication of D. odorifera. MethodThe volatile components in D. odorifera and its counterfeits were detected by headspace gas chromatography-mass spectrometry（HS-GC-MS）， and the GC conditions were heated by procedure（the initial temperature of the column was 50 ℃， the retention time was 1 min， and then the temperature was raised to 300 ℃ at 10 ℃ for 10 min）， the carrier gas was helium， and the flow rate was 1.0 mL·min-1， the split ratio was 10∶1， and the injection volume was 1 mL. The MS conditions used electron bombardment ionization（EI） with the scanning range of m/z 35-550. The compound species were identified by database matching， the relative content of each component was calculated by the peak area normalization method， and principal component analysis（PCA）， orthogonal partial least squares-discrimination analysis（OPLS-DA） and cluster analysis were performed on the detection results by SIMCA 14.1 software， and the differential components of D. odorifera and its counterfeits were screened out according to the variable importance in the projection（VIP） value>2 and P<0.05. ResultA total of 26， 17， 8， 22， 24 and 7 volatile components were identified from D. odorifera， D. bariensis， D. latifolia， D. benthamii， D. pinnata and D. cochinchinensis， respectively. Among them， there were 11 unique volatile components of D. odorifera， 6 unique volatile components of D. bariensis， 3 unique volatile components of D. latifolia， 6 unique volatile components of D. benthamii， 8 unique volatile components of D. pinnata， 4 unique volatile components of D. cochinchinensis. The PCA results showed that， except for D. latifolia and D. cochinchinensis， which could not be clearly distinguished， D. odorifera and other counterfeits could be distributed in a certain area， respectively. The OPLS-DA results showed that D. odorifera and its five counterfeits were clustered into one group each， indicating significant differences in volatile components between D. odorifera and its counterfeits. Finally， a total of 31 differential markers of volatile components between D. odoriferae and its counterfeits were screened. ConclusionHS-GC-MS combined with SIMCA 14.1 software can systematically elucidate the volatile differential components between D. odorifera and its counterfeits， which is suitable for rapid identification of them.

Research advances in liver cancer organoids / 临床肝胆病杂志

Organoids are a novel disease model that is self-assembled from stem cells or malignant tumors and is used in clinical research. They are similar to tissues and organs in the body and have partially functional 3D cell structures. There are two types of traditional models for liver cancer research， i.e.， in vivo models （animal models of liver cancer established by induction） and in vitro cell experiments using corresponding cell lines. Organoids have the advantages of the two types of traditional models and show unique advantages in tumor research. Traditional models cannot fully reflect the microenvironment of cells， which often leads to the inconsistency with clinical research findings， and the emergence of new research models provides a new direction for the research on liver cancer. This article reviews the research advances in liver cancer organoids， in order to provide a new perspective for future research on liver cancer.

Efficacy of aripiprazole combined with olanzapine for hospitalized male patients with schizophrenia and its effect on metabolic syndrome / 四川精神卫生

BackgroundSchizophrenia and the use of antipsychotic medications are identified to be the likely contributors to the development of metabolic syndrome （MS） and cardiovascular disease， and jeopardize the prognosis of schizophrenia. Therefore， effectively preventing or reducing the risk of developing MS in patients with schizophrenia is critical. ObjectiveTo explore the efficacy of aripiprazole combined with olanzapine for male schizophrenia patients and its effect on MS， so as to provide a certain reference for the selection of antipsychotic drugs for schizophrenia patients. MethodsMale patients （n=80） who were hospitalized in The Third People's Hospital of Meizhou from February to June 2023 and fulfilling the International Classification of Diseases， tenth edition （ICD-10） diagnostic criteria for the schizophrenia were enrolled， and grouped using random number table method， each with 40 cases. Study group was treated with aripiprazole combined with olanzapine， while control group was given aripiprazole monotherapy. The treatment lasted for 6 continuous weeks in both groups. At the baseline， Positive and Negative Symptom Scale （PANSS） score， MS-related indices ［fasting plasma glucose （FPG）， hemoglobin A1c （HbA1c）， body mass index （BMI）， waist-to-hip ratio （WHR）， lipid profile］， S100 calcium-binding protein B （S100B） and high sensitivity C-reactive protein （hs-CRP） were recorded. Then the PANSS scores at the end of the 2nd， 4th and 6th week of treatment， the Clinical Global Impression （CGI） scores at the end of the 2nd and 6th week of treatment， as well as the MS-related indices， S100B， hs-CRP， Treatment Emergent Symptom Scale （TESS） score and Rating Scale for Extrapyramidal Side Effects （RSESE） score at the end of the 6th week of treatment were recorded in all participants. ResultsAnalysis on PANSS score revealed a significant group effect， time effect and group×time interaction effect （F=18.092， 634.780， 2.917， P<0.05 or 0.01）. Analysis on CGI score revealed a significant group effect and time effect （F=20.492， 99.190， P<0.01）. At the end of the 6th week of treatment， study group detected lower serum concentrations of HbA1c and triglyceride （TG） compared with control group （t=-3.495， -3.293， P<0.05）. The post-treatment hs-CRP level was lower in study group than that in control group （t=-3.916， P<0.05）. Study group scored lower on TESS compared with control group （t=-4.684， P<0.01）. ConclusionAripiprazole combined with olanzapine can effectively alleviate psychotic states in male schizophrenia patients， and the combination therapy yields less impact on MS-related indices than olanzapine monotherapy. ［Funded by Meizhou Science and Technology Plan Project （number， 2022B116）］

Expression and role of triggering receptor expressed on myeloid cells 2 in high glucose-treated microglia / 基础医学与临床

Objective To explore the expression of triggering receptor expressed on myeloid cells 2(TREM2)in high-glucose microglia and to investigate the role of TREM2 in the proliferation,migration and phagocytosis of high-glucose microglia.Methods Microglia cells were divided into control group and high-glucose treatment group(67.5 mmol/L glucose,24 h).The microglia cells were counted and the expression of Iba1 and TREM2 was de-tected.TREM2 siRNA was transfected to detect the proliferation and migration of microglia.The amyloid β-peptide(Aβ)with a fluorescent tag was added to observe the phagocytosis of Aβ by microglia.Results Compared to normal microglia,the number of microglia significantly decreased after high-glucose treatment(P＜0.001),while the ex-pression of TREM2 and Iba1 markedly increased(P＜0.001).High glucose and TREM2 did not affect the prolifer-ation of microglia.Compared to the normal group,the migration of microglia significantly decreased after high-glu-cose treatment(P＜0.05)and TREM2 did not affect the migration ability of high-glucose microglia.Compared to the normal group,the phagocytosis of Aβ by microglia significantly decreased in the high-glucose treated group(P＜0.001).Furthermore,TREM2 knockdown further decreased the phagocytosis of Aβ by high-glucose microglia(P＜0.001).Conclusions The expression of TREM2 in microglia significantly increases after high-glucose treat-ment,which significantly affects phagocytosis of Aβ by microglia.

Analysis of influencing factors and pathway of self-regulatory fatigue in maintenance hemodialysis patients / 中华护理杂志

Objective Based on the process theory of stress effect,the structural equation model of the influencing factors of self-regulatory fatigue in maintenance hemodialysis patients is constructed,which provides theoretical bases and references for the formulation of intervention programs to relieve self-regulatory fatigue in patients.Method A total of 420 maintenance hemodialysis patients were surveyed using General Information Questionnaire,Self-Regulatory Fatigue Scale,Dialysis Symptom Index,Life Orientation Test-Revised,Perceived Social Support Scale,Brief Illness Perception Questionnaire and Medical Coping Styles Questionnaire.Results Total score of self-regulatory fatigue in maintenance hemodialysis patients was(49.52±10.93),and self-regulatory fatigue showed significant positive correlation with symptom distress,the illness perception,avoidance coping style,yieldly coping(r=0.476,0.428,0.303,0.611,all P＜0.01);self-regulatory fatigue showed significant negative correlation with perceived social support and dispositional optimism(r=-0.410,-0.652,all P＜0.01);it showed no significant correlation with facing coping(r=-0.032,P＞0.05).The Bootstrap analysis revealed that the mediation effect of yielding coping,dispositional optimism,perceived social support,and illness perception between symptom distress and self-regulatory fatigue was significant(95％CI:0.027～0.203).The overall effect of symptom distress on self-regulatory fatigue was(P＜0.001,95％CI:0.576～0.751);the direct effect was(P＜0.001,95％CI:0.170～0.357);the indirect effect was(P＜0.001,95％CI:0.332～0.485);the mediation effect accounted for 61.1％of the total effect value.Conclusion Maintenance hemodialysis patients have a high degree of self-regulatory fatigue,which needs to be further improved.Medical staff should timely identify and evaluate the symptom distress of patients,focus on guiding patients to adjust optimistic disease,provide patients with psychological guidance and stress coping strategies,reduce the negative coping behavior tendency,guide the patients correctly perceive support and care in social relations,help patients set up the correct disease cognition,thus reducing the patient's self-regulatory fatigue.

Association between telomere length in the DNA of peripheral blood leukocytes and the propofol dose in anesthesia induction: an observational study

Abstract Introduction: Propofol is a widely used anesthetic and its dose is closely related to aging. Telomere length (TL) is a unique heritable trait, and emerging as a biomarker of aging, health and disease. Telomerase RNA component (TERC) plays an important role in maintaining TL. We proposed a hypothesis that propofol dose in general anesthesia can be predicted by measuring TL before operation, which greatly reduced the risk of anesthesia, especially the elderly. Methods: The association between the propofol dose in anesthesia induction and: TL in the DNA of peripheral blood leukocytes; body weight; sex; difference of the Bispectral Index (BIS) before and after anesthesia induction in patients was evaluated by multivariable linear regression analyses. The mutation at the 5'end or 3'end of TERC was detected. We recruited 100 patients of elective surgery. Results: We found that propofol dose in anesthesia induction was clearly correlated significantly with TL (r = 0.78, p < 0.001), body weight (r = 0.84, p = 0.004), sex (r = 0.83, p= 0.84, p = 0.004), sex (r = 0.83, p = 0.004), and difference of BIS before and after anesthesia induction (r = 0.85, p = 0.029). By comparing the absolute values of standardized regression coefficients (0.58, 0.21, 0.19, and 0.12) of the four variables, it can be seen that TL contributes the most to the propofol dose in anesthesia induction. However, the mutation at the 5' end or 3' end of TERC was not found. Conclusions: These findings provide preliminary evidence that the propofol dose in anesthesia induction was clearly correlated with genetically determined TL. TL may be a promising predictor of the propofol dose, which is beneficial to improve the safety of anesthesia and reduce perioperative complications.

Association between serum alkaline phosphatase and type 2 diabetes mellitus with nonalcoholic fatty liver disease / 临床肝胆病杂志

Objective To investigate the association between serum alkaline phosphatase (ALP) and type 2 diabetes mellitus (T2DM) with nonalcoholic fatty liver disease (NAFLD). Methods A total of 599 patients with T2DM who were hospitalized in Department of Endocrinology, Affiliated Hospital of Jiangsu University, from July 2016 to December 2018 were enrolled as subjects. According to the presence or absence of NAFLD, the patients were divided into NAFLD group with 286 patients and non-NAFLD group with 313 patients, and according to the results of abdominal ultrasound, the patients with NAFLD were divided into mild group with 111 patients, moderate group with 105 patients, and severe group with 70 patients. General clinical data were compared between groups. The independent samples t - test was used for comparison of normally distributed continuous data between two groups, and an analysis of variance was used for comparison between three groups; the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the Kruskal-Wallis H test was used for comparison between three groups; the chi-square test was used for comparison of categorical data between groups. Pearson correlation analysis and Spearman correlation analysis were used to investigate the correlation between ALP and clinical indices, and a logistic regression analysis was used to investigate the influencing factors for NAFLD. Results Compared with the non-NAFLD group, the NAFLD group had significantly higher proportion of patients with history of hypertension ( χ 2 =7.864, P < 0.05), systolic blood pressure ( t =-2.226, P < 0.05), diastolic blood pressure ( t =-3.800, P < 0.05), body mass index (BMI) ( t =-11.842, P < 0.05), waist circumference (WC) ( t =-9.150, P < 0.05), fasting insulin (FINS) ( Z =-6.173, P < 0.05), fasting C-peptide ( t =-5.419, P < 0.05), serum uric acid ( t =-4.957, P < 0.05), low-density lipoprotein cholesterol ( t =-2.702, P < 0.05), triglyceride ( Z =-9.376, P < 0.05), total cholesterol (TC) ( t =-3.016, P < 0.05), Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) ( Z =-5.794, P < 0.05), alanine aminotransferase (ALT) ( Z =-6.737, P < 0.05), aspartate aminotransferase (AST) ( Z =-4.389, P < 0.05), gamma-glutamyl transpeptidase (GGT) ( Z =-7.764, P < 0.05), and ALP ( t =-2.833, P < 0.05), as well as significantly lower age ( t =2.184, P < 0.05) and high-density lipoprotein cholesterol ( Z =-5.273, P < 0.05). The severity of NAFLD (mild, moderate or severe) was positively correlated with age ( r s =0.140, P < 0.05), BMI ( r s =0.239, P < 0.05), WC ( r s =0.222, P < 0.05), FINS ( r s =0.191, P < 0.05), HOMA-IR ( r s =0.218, P < 0.05), ALT ( r s =0.188, P < 0.05), AST ( r s =0.279, P < 0.05), GGT ( r s =0.202, P < 0.05), and ALP ( r s =0.361, P < 0.05). In the patients with T2DM and NAFLD, ALP was positively correlated with HbAlc ( r =0.149, P < 0.05), fasting plasma glucose ( r =0.146, P < 0.05), HOMA-IR ( r s =0.132, P < 0.05), TC ( r =0.151, P < 0.05), ALT ( r s =0.210, P < 0.05), AST ( r s =0.192, P < 0.05), and GGT ( r s =0.297, P < 0.05). The logistic regression analysis showed that ALP was an influencing factor for NAFLD in patients with T2DM (odds ratio=1.013, 95% confidence interval: 1.004-1.023, P < 0.05). Conclusion Elevated serum ALP is a risk factor for T2DM with NAFLD and is closely associated with hyperglycemia, insulin resistance, and hyperlipemia, and ALP may play a role in the development and progression of T2DM and NAFLD.

Mechanism of M2 macrophage-derived exosomes in promoting the migration of glioblastoma via transferring miR-1260b / 中国药科大学学报

@#Tumor-associated macrophage promotes the progression of glioblastoma (GBM) by infiltrating into tumor tissue, yet its mechanism has not been fully elucidated.This paper aimed to investigate the mechanism of M2 macrophages in affecting the migratory capacity of GBM via secreting exosomes.Ultracentrifugation was used to extract exosomes; RNA sequencing was carried out to screen differentially expressed miRNAs; target prediction database was used to predict the possible target proteins of miRNA; Dual-luciferase reporter assay was performed to verify the interaction between miRNA and target genes; and the proliferation ability of tumor cells was detected by subcutaneous xenograft model in nude mice.Results showed that tumor-related macrophages were mainly M2 macrophages, and that exosomes secreted by M2 macrophages could promote the migration of glioma cells.Meanwhile, exosomes secreted by M2 macrophages transported miR-1260b and affected the migration of glioma cells through directly targeted AJAP1, suggesting that exosomes secreted by macrophages could affect the migration ability of GBM through transporting miR-1260b.

Endoscopic treatment of gastric adenocarcinoma of the fundic gland: a report of three cases and a literature review / 中华老年医学杂志

Objective:To analyze and summarize the clinical characteristics, endoscopic manifestations, pathology and treatment of gastric adenocarcinoma of the fundic gland(GA-FD)to promote clinicians' understanding of this disease.Methods:The clinical data of 3 patients with GA-FD admitted to Beijing Hospital from May 2020 to January 2022 were retrospectively analyzed.Among them, 2 presented with abdominal distension or abdominal pain.The other case was diagnosed during follow-up endoscopy after gastrectomy for gastric cancer.A diagnosis of GA-FD was made based on the results of white light imaging, magnifying endoscopy, pathology and immunohistochemistry.In addition, we reviewed the literature about GA-FD between January 1990 and April 2021 from both national and international reports of 195 cases.We analyzed and summarized the endoscopic and pathological characteristics of the disease and insights on its diagnosis and treatment.Results:Of all 198 cases, patients had a male/female ratio of 1.6/1.0 and an average age of 65.3 years(range: 39-87 years).79.82%(91/114)of the patients were negative for Helicobacter pylori.Gastroscopy showed that the average diameter was 8.97 mm, and 89.9%(178/198)of the patients had lesions infiltrating into the submucosa.91.98%(149/162)of the patients had gastric chief cells as the predominant cell type, 98.86%(130/140)had no lymphovascular invasion, and 97.6%(162/166)had no recurrence or metastasis.Conclusions:GA-FD is a rare gastric cancer, with low-grade atypia and highly differentiated tissues.The mechanisms of GA-FD are not clear and the disease is more commonly seen in the elderly.There is no obvious correlation between Helicobacter pylori infections and GA-FD.Gastric chief cells make up the predominant cell type.The results of endoscopy, pathology and immunohistochemistry can help confirm the diagnosis.The prognosis of most cases is good.

Clinical management of hyperthyroidism complicated with liver failure / 中华内分泌代谢杂志

Clinical data from 11 previously diagnosed and treated patients with hyperthyroidism(Graves′ disease) complicated by liver failure were collected. Among them, 4 cases were drug-induced liver injury leading to liver failure, 1 case had a history of schistosomal liver cirrhosis combined with hyperthyroidism, and 6 cases had hyperthyroidism-induced liver injury(HILI) leading to liver failure. During hospitalization, all patients received supportive therapy and symptomatic treatment with β-blockers. Nine patients were treated with glucocorticoids and artificial liver support therapy. Among the 11 patients, 2 died, 8 patients achieved normal thyroid and liver function within 1-12 months after treatment, and 1 patient with liver cirrhosis had stable liver function in the later stage. After improvement in liver function, 7 patients received isotope therapy, 1 patient underwent total thyroidectomy, and 1 patient received medication. These results indicate that the clinical characteristics differ for drug-induced liver injury and HILI-related liver failure. Early initiation of artificial liver support therapy, in addition to β-blockers and glucocorticoids, is important in alleviating thyroid toxicity and liver damage, thus creating an opportunity for subsequent radioactive iodine or surgical treatment.

Effect of sugammadex on postoperative nausea and vomiting after surgery for intracranial aneurysm / 中华外科杂志

Objective: To investigate the effect of sugammadex on postoperative nausea and vomiting(PONV) after intracranial aneurysm surgery. Methods: Data from intracranial aneurysms patients who met the inclusion and exclusion criteria and underwent interventional surgery in the Department of Neurosurgery, Peking University International Hospital from January 2020 to March 2021 were prospectively included. According to the random number table method, the patients were divided by 1∶1 into the neostigmine+atropine group (group N) and the sugammadex group (group S). Use an acceleration muscle relaxation monitor for muscle relaxation monitoring, and administer neostigmine+atropine and sugammadex to block residual muscle relaxation drugs after surgery. The incidence rates of PONV and severity, the appearance of anesthesia, and the correlation between PONV and postoperative complications were recorded in both groups during five periods after surgery: 0-0.5 hours (T1),>0.5-2.0 hours(T2),>2.0-6.0 hours (T3),>6.0-12.0 hours (T4) and >12.0-24.0 hours (T5). Group comparisons of quantitative data were performed by the independent sample t-test, and categorical data was performed by the χ2 or rank sum test. Results: A total of 66 patients were included in the study, including 37 males and 29 female, aged (59.3±15.4) years (range: 18 to 77 years). The incidence rates of PONV of 33 patients in group S at different time periods of T1, T2, T3, T4, and T5 after surgery were respectively 27.3%(9/33),30.3%(10/33),12.1%(4/33),3.0%(1/33),0(0/33),and the incidence rates of PONV of 33 patients in the group N at different time periods of T1, T2, T3, T4 and T5 after surgery were respectively 36.4%(12/33),36.4%(12/33),33.3%(11/33),6.1%(2/33) and 0(0/33).The incidence of PONV was lower in the group S only in the T3 period after reversal than in the group N (χ2=4.227, P=0.040).However, there was no statistically significant difference in the incidence of PONV between the two groups of patients in other periods (all P>0.05). The recovery time for spontaneous breathing in patients in group S was (7.7±1.4) minutes, the extubation time was (12.4±5.3) minutes, and the safe exit time for anesthesia recovery was (12.3±3.4) minutes; the N groups were (13.9±2.0) minutes, (18.2±6.0) minutes, and (18.6±5.2) minutes, respectively; three time periods in group S were shorter than those in group N, and the differences were statistically significant (all P<0.05). The results regarding the occurrence of complications in patients with different levels of PONV at different time intervals after surgery in the two groups were as follows: in the T3 time period of group N, a significant difference was observed only in the occurrence of postoperative complications among patients with different levels of PONV (χ2=24.786, P<0.01). However, in the T4 time period, significant differences were found in the occurrence of postoperative complications among both the same level and different level PONV patients (χ2=15.435, 15.435, both P<0.01). Significant differences were also observed in the occurrence of postoperative complications among the same level and different level PONV patients in both the T3 and T4 time periods of group S (all P<0.01). Conclusion: Sugammadex can be used to reverse muscle relaxation in patients undergoing intracranial aneurysm intervention surgery,and it does not have a significant impact on the incidence of PONV, it can also optimize the quality of anesthesia recovery and reduce the incidence of complications after intracranial aneurysm embolization surgery.

Analysis of characteristics of drug resistance gene mutation in HBV RT region of hepatitis B infected patients / 中华预防医学杂志

Objective: This article investigated the clinical characteristics and distribution of drug resistance mutation sites in HBV RT region of hepatitis B infected patients. Methods: Retrospective analysis was made on 1 948 patients with HBV infection, who had been tested for NAs resistance mutation and had a medical history of NAs in the Laboratory Department of the Fifth Medical Center of the PLA General Hospital from January 2020 to December 2021. Basic clinical information and drug resistance related mutation information were recorded. Meanwhile, the serological index data of hepatitis B were collected. Drug resistance gene mutant group and non-mutated group were grouped according to whether the drug resistance genes had a mutation in HBV RT region, and the clinical characteristics and genotype distribution of the two groups were statistically analyzed. The pattern of drug resistance gene mutation, number of mutation sites, drug resistance type and mutation of NAs resistance-related sites were analyzed in 917 patients with drug resistance gene mutation in HBV RT region. χ2 Inspection was used for counting data. Meanwhile, two independent samples t-test and Wilcoxon rank sum test were used for measurement data. Results: Among the 1 948 patients with chronic HBV infection, 917 patients had drug resistance gene mutation in RT region (47.07%). The proportion of patients with acute hepatitis B and CHB in HBV RT resistance gene mutant group was lower than that in the non-mutated group, while the proportion of patients with HBV-related cirrhosis was higher than that in the non-mutated group, these differences were statistically significant. Compared with the non-mutated group in HBV RT region, the age, the positive rates of HBeAg and HBV DNA, and HBV DNA load of these patients were increased in drug resistance gene mutant group, these differences were statistically significant. Genotypes of patients in both groups were dominated by C, followed by B and D. The proportion of patients with genotype C in HBV RT drug resistance gene mutant group was higher than that of non-mutated group, the difference was statistically significant. There were 53 gene mutation patterns in 917 patients with drug resistance gene mutation in HBV RT region, and the main pattern was rtL180M+rtM204V+rtS202G (9.70%). The mutation sites were dominated by 3 (20.74%). There were 5 types of drug resistance, LAM+Ldt (21.25%) was the most. Among the 18 sites that were clearly associated with LAM, ADV, ETV and Ldt resistance in the HBV RT region, 14 sites were mutated, and the most common mutation sites were rtL180M, rtM204V, rtM204 and rtS202G. what's more, the proportion of patients with NAs drug resistance was LAM>Ldt>ETV>ADV. Conclusion: In order to prevent adverse consequences of this study such as disease recurrence or disease progression caused by HBV drug resistance, HBV infected patients, who have long-term use of NAs antiviral therapy, should monitor the level of HBV DNA and drug resistance genes in HBV RT region in order to optimize the treatment plan in time or guide individualized treatment.
