ObjectiveTo explore the influence of electroacupuncture combined with point bloodletting and cupping for facial nerve function recovery in acute stage of idiopathic facial palsy （IFP）. MethodsEighty patients with IFP in the acute stage were randomly divided into 40 cases each in the treatment group and the control group. In the control group， oral prednisone acetate tablets were administered during the acute stage when the disease duration was less than 10 days； and electroacupuncture and flash cupping were provided during the recovery stage when the disease duration was more than 10 days， five times a week. For treatment group in acute stage， the stellate ganglion， vagus nerve stimulation point in the auricular cavity， Yifeng （TE 17） and Tinghui （GB 2） were needled on the affected side on the basis of the treatment of control group， with Yifeng and Tinghui connecting to electroacupuncture apparatus， once a day； point bloodletting and then cupping in Yifeng 2 times a week； in recovery stage， the treatment was the same as that of the control group. Both groups were treated until the 45th day from onset. The primary outcome was the Toronto facial grading system （SFGS）， and the secondary outcomes included house-brackmann （H-B） grade， facial disability index （FDI） score， and number of H-B grade-Ⅰ cases. Adverse events were recorded in both groups. ResultsThe SFGS scores of the patients in both groups were higher on the 10th， 30th and 45th days after onset of disease compared with those before the treatment （P＜0.05）； the H-B grade was lower on the 30th and 45th days after the onset of the disease compared with those before the treatment （P＜0.05）； and the facial disability index physical function （FDIP） and facial disability index social function （FDIS） scores were higher on the 30th and 45th days after onset of disease （P＜0.05）. SFGS scores of patients in the treatment group were significantly higher than those of the control group on the 30th and 45th days after onset （P＜0.05）； H-B grade was significantly lower than that of the control group on the 30th and 45th days after onset （P＜0.05）； and FDIP scores on the 45th day after onset， and FDIS scores on the 30th and 45th days after onset were significantly higher than those of the control group （P＜0.05）. At the end of treatment， 77.50% （31 cases） achieved H-B grade-Ⅰ in the treatment group， which was more than 55.00% （22 cases） in the control group （P＜0.05）. No adverse events occurred in either group. ConclusionElectroacupuncture combined with point bloodletting and cupping for IFP in acute stage can improve the recovery degree of facial nerve function， improve effectiveness， and show a high degree of safety.

Objective To investigate whether a stable and reliable hyperuricemia model can be established in mice with an ICR background via a triple-modeling method(combined potassium oxazine,hypoxanthine,and 30％yeast paste),and to evaluate the effect of the positive drug febuxostat on the model.Methods A hyperuricemia model of ICR mice was established using a single drug or double-or triple-drug combinations.Serum uric acid and creatinine concentrations,xanthine oxidase(XOD)and urate oxidase(UOX)activity,and uric acid transporter(URAT)1,glucose transporter(Glut)9,anion transporter(OAT)1,and ATP-binding box subfamily G member(ABCG)2 mRNA levels were detected to evaluate whether the hyperuricemia model was formed successfully.Results The serum uric acid levels of ICR mice were not significantly changed by potassium oxazine alone,as they showed an increase but were not significantly different to those of the 30％yeast paste diet or hypoxanthine combined groups.Serum uric acid levels in the triple administration group were significantly increased at 7 days(P＜0.01),while XOD enzyme activity had increased(P＜0.01)and UOX enzyme activity decreased(P＜0.001)at the same timepoint.There were increased expression levels of URAT1 and Glut9(P＜0.05,P＜0.001),and decreased expression levels of OAT1 and ABCG2(P＜0.001).During dynamic monitoring,the blood uric acid levels of triple administration-induced ICR mice peaked at 7 days.In addition,triple administration-induced hyperuricemia in ICR mice was sensitive to the positive drug febuxostat,which caused a significant decrease in blood uric acid levels(P＜0.001).Conclusions A hyperuricemia model in ICR mice can be stably induced by triple administration for 7 days.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

OBJECTIVES: Hereditary spherocytosis (HS) is the most common hereditary defect of the red cell membrane, mainly characterized by anemia, jaundice, and splenomegaly. Due to the atypical clinical manifestations and negative family history of some patients, as well as the low sensitivity and specificity of traditional laboratory examinations, it is easy for it to escape diagnosis or be misdiagnosed. At present, it has been confirmed that the mutation of ANK1, SPTB, SPTA1, SLC4A1 and EPB42 genes can cause the deletion of their corresponding coding proteins, and thus lead to the defect of erythrocyte membrane. This study aims to analyze the feasibility and clinical application value of HS gene diagnosis. METHODS: Data of 26 patients from Hunan, China with HS admitted to the Department of Hematology, Second Xiangya Hospital of Central South University from January 2018 to September 2021 were retrospectively collected, and their clinical manifestations and results of laboratory examinations were analyzed. Next-generation sequencing (NGS) combined with Sanger sequencing were applied. The mutation of HS pathogenic gene and the variation of uridine diphosphate-glucuronosyl transferase 1 family polypeptide A1 (UGT1A1), a key enzyme in the regulation of bilirubin metabolism, were detected. The results of pathogenic gene variations were interpreted pathogenic gene variations in accordance with the Standards and guidelines for the interpretation of sequence variants published by the American College of Medical Genetics and Genomics (ACMG). The clinical characteristics of patients with different gene variants were analyzed, and the clinical diagnosis and genetic diagnosis were compared. RESULTS: Among the 26 patients with HS, there were 23 cases of anemia, 25 cases of jaundice, 24 cases of splenomegaly, and 14 cases of cholelithiasis. There were 16 cases with family history and 10 cases without family history. The results of HS mutation test were positive in 25 cases and negative in 1 case. A total of 18 heterozygous mutations of HS pathogenic genes were detected in 19 families, among which 14 were pathogenic, 1 was likely pathogenic and 3 were of unknown significance. SPTB mutations (12) and ANK1 mutations (4) were the most common. The main variation types were nonsense mutation (9). There were no significant differences in peripheral blood cell parameters and hemolysis indicators between the SPTB mutant group and the ANK1 mutant group (all P>0.05). The rate of splenectomy in ANK1 mutation group was higher than that in SPTB mutation group, and the difference was statistically significant (χ²=6.970, P=0.014). There were no significant differences in peripheral blood cell parameters and hemolysis indicators among different mutation types (nonsense mutation, frameshift mutation, splice site mutation and missense mutation) (all P>0.05). Among the 18 clinically confirmedpatients, there were 17 cases whose diagnosis is consistent with the genetic diagnosis. Eight patients were clinically suspected, and all of them were confirmed by detection of HS gene mutation. Twenty-four patients with HS underwent UGT1A1 mutation detection, among which 5 patients carried UGT1A1 mutation resulting in a decrease in enzyme activity, and 19 patients had normal enzyme activity. The level of total bilirubin (TBIL) in the group with reduced enzyme activity was higher than that in the group with normal enzyme activity, and the difference was statistically significant (U=22, P=0.038). CONCLUSIONS Most patients with HS have anemia, jaundice and splenomegaly, often accompanied by cholelithiasis. SPTB and ANK1 mutations are the most common mutations in HS pathogenic genes among patients in Hunan, China, and there was no significant correlation between genotype and clinical phenotype. Genetic diagnosis is highly consistent with clinical diagnosis. The decrease of UGT1A1 enzyme activity can lead to the aggravation of jaundice in HS patients. Clinical combined gene diagnosis is beneficial for the rapid and precision diagnosis of HS. The detection of UGT1A1 enzyme activity related gene variation plays an important role in evaluation of HS jaundice.

Objective: To investigate the affecting factors of type 1 diabetes mellitus(T1DM) in children, and to provide reference for the prevention and treatment measures in the future. Methods: A case-control study was carried out among 106 children diagnosed with T1DM in a hospital in Shenyang. At the same time, 106 healthy children were selected as the control group by 1∶1 matching of age, gender and living area. The early life-related factors that may affect the development of T1DM in two groups were investigated by questionnaire. Results: The average age of diagnosis in 106 cases with T1DM was(8.02±3.49) years, girls accounted for 60.4% and boys 39.6%. Multi-factor Logistic regression analysis showed that high family socioeconomic status and higher education of fathers were associated with lower odds of development of T1DM. Family member smoking(OR=2.51, 95%CI=1.19-5.29), family history of diabetes(OR=2.56, 95%CI=1.18-5.55), maternal obesity(OR=5.42, 95%CI=2.49-11.83) and infection during pregnancy(OR=3.45, 95%CI=1.04-11.46) were associated with higher risk of T1DM(P<0.05). Conclusion The occurrence of T1DM in children is affected by many factors including heredity, maternal health during pregnancy and family economy,highlighting the importance of early life prevention of T1DM.

Objective: To understand the prevalence of overweight and obesity, dietary habits and main food intake frequency among primary school students in Shenyang, so as to provide a reference for exploring the effect of diet related factors on the development of overweight and obesity in children. Methods: A total of 2 041 students from two primary schools in a certain district of Shenyang were selected by convenience sampling in May 2017, with height and weight measured, meanwhile the questionnaire survey regarding dietary habits and the frequency of main food intake were administered. Results: The rates of overweight and obesity were 18.4% and 22.1% respectively, and the rate of overweight and obesity in boys (21.0%，27.8%) were significantly higher than that in girls (15.8%,16.2%)(χ 2=22.45,53.40，P<0.01). The results of univariate analysis showed that frequency of eating breakfast, eating speed, appetite, picky eaters or not, and the frequency of fruit, seafood and canned food intake were associated with overweight and obesity in primary school students (χ 2=7.67，97.92，229.70，95.88，6.40，6.58，7.96，P<0.05). Multivariate Logistic regression analysis showed that slow eating speed (OR=0.46, 95%CI=0.29-0.69) and normal eating speed (OR=0.47, 95%CI=0.32-0.69) were associated with lower rates of overweight and obesity; good appetite (OR=43.73, 95%CI=5.88-325.36) was associated with higher rates of overweight and obesity in primary school students (P<0.01). Conclusion The detection rate of overweight and obesity is relatively high among primary school students in Shenyang, and the rate of obesity is already higher than that of overweight; The frequency of common food intake has little impact on the development of overweight and obesity in primary school students, but fast eating speed and good appetite are the risks of overweight and obesity among them.

Objective:A retrospective analysis was performed on clinical characteristics and deoxyguanosine kinase DGUOK gene mutations in a family with hepatocerebral mitochondrial DNA depletion syndrome (MTDPS). Methods:The clinical data, treatment process and gene detection results of a child with MTDPS in the second hospital of Hebei Medical University in April 2019 were analyzed and summarized.Results:Proband was a girl.From the first week of infantile, she suffered from recurrent hypoglycemia, hyperlactic acid, progressive cholestatic liver dysfunction, coagulopathy, difficult feeding, slow growth of body mass, microcephaly, hypotonia, and gradul intermittent binocular tremors, and eventually failed to thrive.Gene testing identified two compound heterozygous mutations c. 42-c.43insTTCA(p.F15fs129X)/c.808-1(IVS6)G>A in DGUOK gene.The former was a frame-shift mutation resulted in truncated protein and the later was a splicing mutation resulted in abnormal splicing.Each parent was a heterozygous carrier, and there were no mutations in the two sites with her elder sister. Conclusions:Both mutations were first reported worldwide. DGUOK gene mutations with MTDPS are important causes of infant liver failure.When hypoglycemia, hyperlactic acidemia and liver dysfunction occur in newborn and infant, MTDPS related gene DGUOK gene sequencing screening should be considered for early definitive diagnosis, or, when acute liver failure happen in infant and childhood, neuromuscular involvement is insufficient.

Objective:To investigate the "V" -shaped anatomical approach in the prevention of bile duct injury during laparoscopic complex cholecystectomy and its clinical application value.Methods:The patients with complex gallbladder from June 2020 to June 2021 in the First Affiliated Hospital of Baotou Medical College, Inner Mongolia University of Science and Technology were selected as the research objects, and they were randomly divided into observation group and control group, with 60 cases in each group. All patients underwent laparoscopic cholecystectomy. The observation group underwent laparoscopic cholecystectomy through the triangle "V" shape of the gallbladder, and the control group did not use the "V" shape anatomy. The operation status, complications and postoperative recovery of the two groups of patients were compared.The measurement data of normal distribution were expressed by ( Mean± SD), and t test was used for comparison between groups, and chi-square test was used for comparison between groups of count data. Results:The conversion rate to laparotomy, intraoperative bleeding and operation time of observation group were 3.33%, (97.31±13.27) mL, (65.27±13.82) min, which were significantly lower than those in the control group[8.33%, (111.27±25.18) mL, (81.35±12.12) min], the differences between the two groups were statistically significant( P<0.05). The incidence of biliary injury, total incidence of complications of the observation group were 0, 8.33%, which were significantly lower than those in the control group(6.67%, 28.33%), the differences between the two groups were statistically significant( P<0.05). The postoperative exhaust time, drainage tube retention time, hospitalization cost and hospitalization time of the observation group were (9.89±3.58) h, (32.58±5.17) h, (3 142.92±137.93) yuan, (4.73±1.42) d, and significantly lower than those in the control group [(11.65±2.45) h, (46.18±6.49) h, (3 424.29±156.34) yuan, (5.38±1.25) d], the differences between the two groups were statistically significant ( P<0.05). Conclusions:For laparoscopic complex cholecystectomy, the use of the triangular "V" -shaped gallbladder anatomical approach is more conducive to the operation, can reduce the patient's operation time and intraoperative blood loss, reduce the rate of intraoperative conversion to laparotomy, and reduce biliary tract injury and bile leakage. Such as the incidence of complications, prompting patients to recover as soon as possible, it is worthy of clinical application and promotion.

Objective: To investigate the prevalence and associated factors of eczema in children in order provide reference for the prevention and treatment of eczema. Methods: Two primary schools in a district of Shenyang were randomly selected to conduct a questionnaire survey on 2 240 students in May 2017. Children with eczema need to be diagnosed by a doctor. Results: There were 838 cases of eczema with a reported rate of 37.4%, 38.7% in boys and 36.1% in girls. The age of 6 to 12 months was the peak period of first eczema in children, and the proportion of eczema within 1 year was up to about 70%. Children who have had eczema in the past were now more likely to catch a cold, and the reported rates of allergic rhinitis, asthma and food allergies were also significantly higher. The Logistic regression analysis showed that the mother was unhappy during pregnancy(OR=1.32,95%CI=1.03-1.69), the parents were more educated (OR=1.60, 95%CI=1.19-2.16), and the parents were allergic (OR=1.58,95%CI=1.07-2.33；OR=1.41, 95%CI=1.02-1.94), family history of diabetes(OR=1.95, 95%CI=1.41-2.68), and cesarean(OR=1.33, 95%CI=1.07-1.65) were risk factors of eczema in children. Conclusion The incidence of children eczema is affected by maternal mood during pregnancy, family factors and delivery mode. It is of practical significance to prevent children eczema in early development for reducing the incidence of other allergic diseases in the future.
