Objective:To observe the efficacy and safety of combined lienal polypeptide injection therapy in the treatment of Mycoplasma pneumoniae pneumonia（MPP）in children aged 3 to 14 years old in multiple clinical centers.Methods:A randomized，controlled，multi-center clinical study design was adopted.A total of 240 hospitalized children aged 3 to 14 years old with MPP from 7 hospitals from September 1，2023 to January 31，2024 were included.According to the severity of pneumonia，they were divided into the mild MPP group with 80 cases and the severe MPP/refractory MPP（SMPP/RMPP）group with 160 cases，and then randomly divided into the control group and the experimental group at a ratio of 1 ∶1，using the random number table method.After screening，subjects entered a treatment period of 5 to 7 days.The control group was treated with azithromycin，while the experimental group was treated with azithromycin plus lienal polypeptide injection .The recovery of lung CT，length of hospital stay，duration of fever，cough score，whether mild cases developed into severe or refractory cases，duration of hormone use，use of intravenous immunoglobulin（IVIG），bronchoscopy treatment，and immune function were observed between the two groups to evaluate the efficacy of lienal polypeptide injection.Adverse events after medication，vital signs，blood routine，urine routine，liver function，myocardial enzymes，renal function，and electrocardiogram were observed to evaluate the safety. Results:A total of 231 subjects have completed the trial in the 7 hospitals，including 118 cases in the experimental group and 113 cases in the control group.Main observation index：the rate of lung CT aggravation in the experimental group was lower than that in the control group（2.6% vs 15.3%， P<0.01），and the difference was statistically significant.Secondary indexes：there were no statistically significant differences in the length of hospital stay，duration of fever，cough score，duration of hormone use，whether IVIG treatment was used，the number of bronchoscopy treatment cases，and immunoglobulin between the two groups（all P>0.05）.However，the rate of cases of plastic bronchitis（PB）found under bronchoscopy in the experimental group was lower than that in the control group（0 vs 18.8%， P=0.03），and the difference was statistically significant.Among the mild MPP（72 cases），there were no statistically significant differences in the length of hospital stay，duration of fever，cough score，duration of hormone use，whether IVIG treatment was used，the number of bronchoscopy treatment cases，and the improvement rate of lung CT between the two groups（all P>0.05）.However，compared with the control group，the rate of cases developing into SMPP/RMPP in the experimental group was less（24.3% vs 48.6%， P=0.03），and the difference in IgG before and after treatment was small［0.53（-0.04，1.18）g/L vs 1.33（0.48，2.25）g/L， P=0.01］.Among the SMPP/RMPP cases（159 cases），the rate of cases of PB found under bronchoscopy in the experimental group was less than that in the control group（0 vs 20%， P=0.04），and the rate of cases with aggravated lung CT in the experimental group was less than that in the control group（1.3% vs 19.5%， P<0.01），and the improvement rate of lung CT in the experimental group was higher than that in the control group（88.8% vs 75.3%， P=0.03），with statistically significant differences.There were no statistically significant differences in the length of hospital stay，duration of fever，cough score，duration of hormone use，whether IVIG treatment was used，the number of bronchoscopy treatment cases，and immunoglobulin between the two groups（all P>0.05）.Two cases in the experimental group developed rashes，which improved after the drug was discontinued.There were no serious adverse reactions such as abnormal vital signs like dyspnea and cyanosis due to the use of lienal polypeptide injection.There were no obvious changes in blood routine，liver function，myocardial enzymes，renal function，electrocardiogram，and urine routine values before and after medication compared with the baseline. Conclusion:The combined use of lienal polypeptide injection in the treatment of MPP in children can reduce the probability of the transformation from mild cases to SMPP/RMPP，reduce the rate of aggravation of the image findings，promote the absorption of lung inflammation，reduce the rate of PB found under bronchoscopy，and has good safety.

With the rapid development of information technology， research on ancient TCM books has shifted from the traditional collation and digitization into intelligent knowledge service， thereby achieving the deep integration of ancient TCM books collation and clinical needs. Based on the clinical problem and knowledge element theory， we implemented in-depth indexing and knowledge mining for 600 kinds of ancient TCM books， built a knowledge sharing service platform for ancient TCM books by integrating database， cloud platform， knowledge graph and other technologies， and carried out the thematic literature research and developed databases for four major diseases including stroke， heart failure， liver cirrhosis， and diabetes. The digital intelligence products have been applied in hundreds of hospitals for evaluation and feedback. Finally， through "digital processing plus intelligent application"， the two-way interaction between ancient TCM books and current clinical practice is realized， and the path and paradigm of ancient TCM books knowledge serving the modern prevention and control of major diseases is formed， providing reference for the innovative utilization of ancient TCM books.

Objective:To explore the effect of comprehensive moxibustion with Huolong cupping in patients with lung-spleen qi deficiency type allergic rhinitis.Methods:This study was a randomized controlled trial. From October 2022 to April 2023, convenience sampling was used to select 66 patients with lung-spleen qi deficiency type allergic rhinitis who visited the Otolaryngology Head and Neck Clinic of Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine as the research subject. The patients were randomly divided into an experimental group ( n=33) and a control group ( n=33). Both groups received routine oral Chinese medicine treatment. On the basis of routine treatment, the experimental group performed comprehensive moxibustion with Huolong cupping on the meridians of the Du meridian and bladder meridian. This study compared the scores of Nasal Airway Resistance (NAR), Total Nasal Symptom Score (TNSS), Visual Analogue Scale (VAS), and Chinese version of Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) between two groups of patients before and after intervention. Results:Eventually 30 patients in each of the experimental group and control group completed the study. After intervention, the NAR score of the experimental group was lower than that of the control group, and the difference was statistically significant ( P<0.05). Repeated measures analysis of variance showed that with the increase of treatment time, the TNSS, VAS, and RQLQ scores of the experimental group were lower than those of the control group with statistical differences ( P<0.05), and the time effect, inter group effect, and interaction effect were statistically significant ( P<0.05) . Conclusions:Huolong cupping comprehensive moxibustion can reduce nasal resistance, meliorate nasal symptoms and accompanying nasal symptoms, and improve the quality of life of patients.

Objective:To investigate the application value of peri-gastric devasculariza-tion without dissociation of esophagus for portal hypertension.Methods:The retrospective and descriptive study was conducted. The clinical data of 94 patients with portal hypertension who were admitted to three medical centers, including 75 cases in the People′s Hospital of Ningxia Hui Autonomous Region, 12 cases in the People′s Hospital of Wuhai and 7 cases in the People′s Hospital of Wuzhong, from July 2018 to December 2022 were collected. There were 68 males and 26 females, aged 46(range, 21-70)years. All 94 patients underwent peri-gastric devascularization without dissociation of esophagus. Observation indicators: (1) intraoperative condition; (2) postoperative complications; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and measure-ment data with skewed distribution were represented as M(range). Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Results:(1) Intraoperative condition. All 94 patients underwent surgery success-fully without operation death, including 82 cases receiving open surgery and 12 cases receiving laparoscopic surgery. The operation time and volume of intraoperative blood loss were (183±85)minutes and 289(range, 158-560)mL, respectively, for the 94 patients. (2) Postoperative complications. Of 94 patients, early portal vein thrombosis occurred in 24 cases, intra-abdominal infection occurred in 2 cases, hepatic encephalopathy occurred in 1 case, pulmonary embolism occurred in 1 case, intra-abdominal hemorrhage requiring operation to stop bleeding occurred in 1 case and pleural effusion requiring drainage occurred in 1 case. All patients with postoperative complications were cured after treatment. None of the 94 patient had postoperative esophageal complications such as odynophagia or dysphagia. (3) Follow-up. All 94 patients were followed up for 38(range, 6-60)months. Of the 45 patients with paraesophageal vein, there were 36 cases of thinner and 9 cases of occlusion of the distal subphrenic paraesophageal vein after surgery, respectively. Cases with esophageal varices disappearance, cases with mild and moderate residual of esophageal varices, cases with severe residual of esophageal varices, cases with recurrence of esophageal varices, cases with esophageal varices bleeding were 7, 70, 9, 4, 4 in the 94 patients after surgery. Cases with esophageal varices disappearance was 7 in the 45 patients with paraesophageal vein, versus 0 in the 49 patients without paraesophageal vein, showing a significant difference between them ( P<0.05). Of 94 patients, 17 cases developed postoperative late portal vein thrombosis and cavernous transformation, 7 cases developed liver cancer, 1 case had hepatic encephalopathy, and 6 cases died. Conclusion:Peri-gastric devascularization without dissociation of esophagus is safe and feasible for the treatment of portal hypertension.

Objective:To carry out prenatal screening and diagnosis for a woman with advanced maternal age.Methods:Non-invasive prenatal testing (NIPT) was carried out to determine the risk of fetal chromosome aneuploidy. Aminiocentesis was proceeded for fetal chromosomal karyotyping and copy number variation sequencing (CNV-seq). The fetus was subjected to systematic ultrasound screening in the second trimester.Results:NIPT has indicated there was a loss of fetal sex chromosome. Karotyping of the amniocyte showed a mosaic sex chromosome abnormality 45, X[53]/46, X, + mar[7]. The result of fetal DNA CNV-seq was seq[GRCh37]del(Yq11.1q12) chrY: g. 13 104 553-28 819 361del, seq[GRCh37]del(Yp11.32p11.2) chrY: g. 10 001-9 873 915del (mosaic ratio: 30%). Ultrasonography discovered that the fetus had renal dysplasia and male external genitalia. The karyotypes of the couple were both normal.Conclusion:Multiple genetic tests should be carried out for fetus with a high risk for chromosome aneuploidies signaled by NIPT. It is difficult to predict the post-natal phenotype for fetuses with mosaic sex chromosomal aneuploidies. The couple should be carefully counseled upon genetic counseling.

Their efforts aimed at reducing the stress faced by front-line medical workers, and assisting the patients to achieve body-mind balance for better treatment outcomes." Online+ offline" and" in-cabin+ out-of-cabin" service teams were organized to assist these medical staff, provide social support, and integrate resources. The study analyzed the problems and challenges in the process of practice, and provided a reference for further improving the management of public health emergency services.

Objective To summarize the prenatal diagnosis and genetic counseling of Turner syndrome fetuses with 46,X,i(X)(q10).Methods Two gravidas admitted to the Obstetrics and Gynecology Hospital of Dalian were enrolled in this study.One gravida,who was admitted in October 2016,was classified as high risk of Down syndrome based on prenatal serologic screening and systematic ultrasonography,which found remarkably shorter humeri and femora than fetus of the same gestations.The other was suggested to be monosomy X after non-invasive prenatal testing and admitted in November 2017.Fluorescence in situ hybridization (FISH) and karyotyping were performed for prenatal diagnosis.Peripheral blood karyotyping was also offered to the two women and their partners.Results FISH test for amniotic fluid did not find numerical abnormality in 13,18,21,and sex chromosomes in these two fetuses.Karyotype analysis showed that the two fetuses were both 46,X,i(X) (q10),while their parents were normal.Both cases were terminated after genetic counseling.Conclusions Prenatal serological screening,systematic ultrasonography and non-invasive prenatal testing may help to identify Turner syndrome fetus of 46,X,i(X) (q10).Timely and accurate prenatal diagnosis may prevent the affected fetus from being born.

OBJECTIVETo delineate the nature and origin of chromosomal copy number variants (CNVs) in a boy with mental retardation and multiple congenital malformation.

METHODSThe karyotypes of the patient and his parents were analyzed with routine G-banded chromosomal analysis. Genome DNA was analyzed by next generation sequencing (NGS).

RESULTSThe patient was found to harbor a structural aberration involving chromosome 3p. The karyotype of his father was 46,XY,t(3;7)(p26;q31), while his mother was found to be normal. NGS analysis of the patient revealed a 2.16 Mb microdeletion at 3p26.3-pter and a duplication at 7q31.33-qter.

CONCLUSIONThe structural aberration of 3p carried by the patient has derived from his father whom carried a balanced translocation of t(3;7), and his karyotype was finally determined as 46,XY,der(3) t(3;7)(p26.3;q31.33)pat. The abnormal phenotype of the patient can probably be attributed to the presence of 3p26.3-pter microdeletion and 7q31.33-qter duplication.
