Objective To study the clinical efficacy of digital music gastric electrical pacing for refractory functional dyspepsia concomitant with non-erosive reflux disease, and its effects on mental health and life-quality of the patients. Methods According to the Rome III criteria and Montreal consensus in diagnosis of gastroesophageal reflux disease, 50 patients with concomitant refractory functional dyspepsia and non-erosive reflux disease were recruited. The clinical efficacy of digital music gastric electrical pacing were evaluated using the score of clinical symptoms before treatment and 15 days after treatment, and the mental health and life-quality of patients were assessed using symptom checklist 90. Results Main symptoms, including upper abdominal pain, abdominal fullness, early satiety, belching, hiccup, nausea, heartburn, acid reflux (daytime), nocturnal acid reflux, loss of appetite and sleep, were significantly improved 15 days after treatment compared with those of pre-treatment, and there were statistically significant differences (all P<0.005). The significant response rate/response rate (efficacy rate) were 59.0%/100.0%, 59.3%/96.3%, 47.0%/94.1%, 61.3%/96.8%, 86.7%/100.0%, 80.0%/100.0%, 64.3%/92.9%, 73.7%/89.5%, 64.3%/85.7%, 90.0%/90.0%, 36.7%/93.3% respectively. After treatment for 15 days, the overall response rate of symptom relief was 94.4% in patients and the overall significant response rate was 65.7%. The symptom scores of somatization, obsessive-compulsiveness, depression, and anxiety were significantly improved, and the differences were statistically significant (all P<0.01). Conclusion The clinical efficacy of digital music gastric electrical pacing is significant for refractory functional dyspepsia concomitant with nonerosive reflux disease, and it is expected to be a new option for the treatment of this disease complex.

OBJECTIVETo investigate the specific antitumor immune response induced by idiotype protein (Id)-pulsed dendritic cells (DC) in vitro.

METHODSDC was generated from peripheral blood monocytes of the multiple myeloma (MM) patients using GM-CSF, IL-4, and TNF-alpha. The DCs were pulsed with idiotypic fragment, the F(ab')2 fragment of M protein from MM patient at the immature stage. The morphologic characteristics of the cells were observed with light and electron microscopes. The phenotypic features were analyzed with FACS, MTT assay was employed to evaluate the proliferation of autologous T cells and the inhibition rate of MM cells.

RESULTSDC precursors in peripheral blood could be induced to typical mature DC in medium containing GM-CSF, IL-4 and TNF-alpha. Mature DC with Id could increase the proliferation of the autologous T cells and activate naive T cells to become tumor specialized cytotoxic T lymphocytes (CTL). The CTL at different doses showed significant inhibition on or killing ability to autologous MM cells in vitro.

CONCLUSIONSIn a suitable cytokine environment, the DC precursors from peripheral blood of MM patients could be induced to functional DC, and vaccination of Id-pulsed DC could induce active antitumor immune response.

Objective To investigate the effect of percutaneous cardiac intervention (PCI) on the clinical prognosis in aged patients with coronary heart disease (CHD) involving multiple coronary arteries who obtained complete revascularization (CR) or incomplete revascularization (ICR) after PCI.Methods A total of consecutive 257 aged patients (＞75 years old) with confirmed CHD that involved multiple coronary arteries,who were admitted to authors' hospital during the period from January 2015 to September 2015 to receive PCI,were enrolled in this study.Based on the complete revascularization (CR) or incomplete revascularization (ICR) after PCI,the patients were divided into CR group and ICR group.The basic clinical data,PCI parameters and the occurrence of major adverse cardiovascular and cerebrovascular events (MACCE) in hospitalization days and in the follow-up period were compared between the two groups.Results CR group included 171 patients (66.53％) and ICR group included 86 patients (33.47％).The hypertension history,diabetes history,diagnosis of acute non-ST segment elevation myocardial infarction or myocardial occlusion disease at admission,chest tightness,palpitation and other discomfort symptoms occurring in one and 3 months after PCI,and re-hospitalization rate in ICR group were significantly higher than those in CR group (P＜0.05).No statistically significant differences in the incidence of MACCE during hospitalization days and at one,3 and 6 months after PCI existed between the two groups (P＞0.05).Conclusion In aged patients with CHD that affects multiple coronary arteries,ICR does not increase the risk of MACCE after PCI,although the re-hospitalization rate and the incidence of postoperative discomfort symptoms will be increased.The long-term prognosis needs to be further studied.

OBJECTIVE: To investigate the prognostic value of the serum calcium level corrected by serum albumin (cCA) and corrected serum lactate dehydrogenase (LDH) level for the risk stratification for newly diagnosed multiple myeloma (MM) patients. METHODS: The clinical data and survival of 186 newly diagnosed MM patients admitted to our hospital from June 1, 2015 to November 1, 2017 were collected. The patients's survival time was obtained by telephone and follow-up visits to patients and their families. The value of the prognostic system consisting of cCA levels and LDH levels in the survival time of MM patients was retrospectively analyzed. Moreover, the post-corrected hypercalcemia and high LDH as 2 factors were used for risk stratification, then according to these 2 factors, the MM patients were divided into 3 groups: group 1 (no risk factor), group 2 (1 risk factor) and group 3 (2 risk factors), and the effect of risk factors on the prognosis of MM patients was analyzed. RESULTS: The median follow-up time was 16 months. The cumulative OS rate of the post-corrected hypercalcemia group was lower than that of the non-hypercalcemia group. The 1-year cumulative OS rate in the 2 groups was 79.0%±6.7% and 88.6%±3.0%, the 3-year cumulative OS rate was 53.0%±10.5% and 74.6%±6.6% (P=0.016), respectively. The cumulative OS rate of the high LDH group [LDH ＞upper limit of normal (ULN), ULN=250 U/L] was lower than that in the normal LDH group. The 1-year cumulative OS rate in the 2 groups was 71.6%±8.6% and 90.0%±2.8%, the 2-year cumulative OS rate was 44.9%±12.1% and 83.1%±4.0%, respectively, and the median OS time was 19 months (95%CI: 15.32-23.34) and not reached (P=0.001). The risk stratification analysis showed that the median OS time of the 3 group was not reached (n=103, 57%), not reached (n=70, 39%) and 17 months (n=7, 4%, 95%CI: 5.19-28.41, P＜0.001). Patients with two risk factors had a prognosis worse than patients with 0-1 risk factor. CONCLUSION The prognostic combination of corrected serum calcium and LDH levels may provide a basis for risk stratification and prognosis in MM patients in clinical practice.

ObjectiveTo explore the material basis and mechanism of Nardostachyos Radix et Rhizoma （NRER）-Agrimoniae Herba （AH）， the herbal pair effective in regulating the liver， invigorating Qi， and calming palpitations， in the treatment of premature ventricular contractions （PVCs） by network pharmacology and molecular docking. MethodThe chemical components and targets of NRER and AH were collected from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） combined with relevant literature. GeneCards，Online Mendelian Inheritance in Man（OMIM），and DrugBank were used to predict the potential targets against PVCs. STRING platform was used for protein-protein interaction （PPI） analysis. Metascape platform was used for Gene Ontology（GO） and Kyoto Encyclopedia of Genes and Genomes（KEGG） enrichment analysis. Cytoscape 3.8.0 was used to construct the NRER-AH component-potential target-signaling pathway network. The main target proteins underwent molecular docking to the active components of NRER-AH by AutoDock 4.2.6. ResultThe targets of nine active components in NRER-AH （such as quercetin，kaempferol，and acacetin） against PVCs mainly involved tumor necrosis factor （TNF），mitogen-activated protein kinase 1（MAPK1），and protein kinase B1（Akt1）. The potential targets were mainly enriched in 26 signaling pathways，such as pathways in cancer and the advanced glycosylation end product （AGE）-receptor of advanced glycosylation end product（RAGE） signaling pathway. The results of molecular docking showed that the majority of the active components （92.59%） of NRER-AH had good binding activities with the main target proteins TNF，MAPK1，and Akt1. ConclusionThe active components of NRER-AH can regulate cardiac ion channels，resist inflammation， and combat oxidative stress to treat PVCs through multi-target and multi-pathway interventions. They can also improve symptoms related to depression and anxiety by inhibiting monoamine oxidase activity and protecting nerves from damage. This study is expected to provide research ideas and the theoretical basis for further exploring the material basis and mechanism of NRER-AH in the treatment of PVCs.

Indigo Naturalis( IN) is mainly composed of 10% organic matter and 90% inorganic matter,with a poor wettability and strong hydrophobicity. Indigo,indirubin and effective ingredients are almost insoluble in water. And how it exerts its effect after oral administration still needs to be revealed. For this reason,this study put forward the hypothesis that " Indigo Naturalis forms a slightly soluble calcium carbonate carrier in a strong acid environment of gastric fluid,and organic substances are solubilized in the bile environment of intestinal fluid",and then verified the hypothesis. First,the dissolution apparatus was used to simulate the change process of IN in different digestive fluid,and the effects of low-dose and normal bile on the dissolution of inorganic substances and the release of organic substances were compared. After the surface morphology and element changes of IN in different digestive fluid were observed,it was found that bile is the key to promoting the dissolution of organic and inorganic substances in IN. Furthermore,the rat fever model induced by 2,4-dinitrophenol was used to study the antipyretic effect of IN in normal rats and bile duct ligation rats. It was found that the antipyretic effect of IN on normal rats was better than that of bile duct ligation rats. The above results indicated that after oral administration of IN,the calcium carbonate carrier was transformed into a slightly soluble state in acidic gastric fluid,and a small amount of organic matter was released. When IN entered the intestinal fluid mixed with bile,the carrier dissolved in a large amount,and indigo and indirubin were dissolved in a large amount,so as to absorb the blood and exert the effect. This study has a certain significance for guiding clinical application of IN. For patients with insufficient bile secretion( such as bile duct resection),oral administration with IN may not be effective and shall be paid attention.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.
