Bronchiectasis has the characteristics of long course,gradual aggravation,easy recurrence and difficult to treat.The characteristics are similar to those arouse by incubative pathogenic factors.Based on the theory of incubative pathogenic factors,this disease is often related to the incubative pathogenic factors in the body's areas with deficient healthy qi,which occur at regular times.The etiology can be external,congenital,or internal.Treatment should focus on different characteristics of incubative pathogenic factors.Attention should be paid to clearing and dispersing in external pathogenic factors,while attention should be paid to supporting and promoting healthy qi in congenital pathogenic factors,and do not forget to remove internal pathogenic factors.

Objective:To explore the curative efficacy of Dingke Decoction in the treatment of post infectious cough based on the the real-world clinical data.Methods:Retrospective cohort study was conducted. 245 patients with cough after infection in the hospital of Jingan Chinese Medical Hospital from July 2021 to July 2022 were set as study objects. The fact that whether the patients with Dingke Decoction or not were divided into control group (90 cases, without Dingke Decoction) and treatment group (155 cases, with Dingke Decoction). By using propensity nearest neighbor 1:1 matching to balance the confounding factors before treatment, 56 cases were successfully matched in both groups. The control group was treated symptomatically according to the actual clinical situation, while the treatment group was treated with modified Dingke Decoction on the basis of symptomatic treatment in the control group. The treatment for both groups lasted for 2 weeks. TCM symptom scores and cough severity score were evaluated using the Leicester Cough Quality of Life Questionnaire (LCQ) before and after treatment. Levels of tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) were detected through ELISA; adverse reactions during the treatment were recorded, and the clinical efficacy was evaluated.Results:The total effective rate of the treatment group was 91.07% (51/56), while that of the control group was 76.79% (43/56), with a statistically significant difference between the two groups ( χ2=4.24, P=0.040). The daytime cough symptom score (1.03 ± 0.67 vs. 1.20 ± 0.66, t=7.40) and nighttime cough symptom score (0.74 ± 0.62 vs. 1.26 ± 0.54, t=6.27) in the treatment group were lower than those in the control group after treatment ( P<0.001). After treatment, the LCQ physiological (5.30 ± 0.79 vs. 4.78 ± 1.09, t=-2.44), psychological (5.33 ± 0.92 vs. 4.70 ± 1.12, t=-2.39), and social (5.23 ± 0.94 vs. 4.60 ± 0.81, t=-2.86) scores in the treatment group were higher than those in the control group ( P<0.05). After treatment, he treatment group serum IL-6 [(14.29 ± 3.94) ng/L vs. (19.99 ± 5.17) ng/L, t=4.80] and TNF-α [(36.23 ± 7.83) ng/L vs. (42.44 ± 7.63) ng/L, t=3.11] were lower than those in the control group ( P<0.01). The incidence of adverse reactions in the control group was 8.92% (5/56) and 5.36% (3/56), respectively, without statistical significance ( χ2=0.54, P=0.716). Conclusion:Based on the real-world research method, medicine Dingke Decoction can improve the clinical efficacy and the quality life of post infectious cough patients, and the mechanism may be related to reducing airway inflammation response.

Osteoporosis can be induced by various factors including prolonged glucocorticoid usage, diminished estrogen levels, secondary hyperparathyroidism, and alterations in the microenvironment of bone tissue. The bone metabolism imbalance(osteogenic-lipogenic imbalance) plays a crucial role in the development of osteoporosis. This imbalance is primarily driven by an increase in the differentiation of bone marrow mesenchymal stem cells into adipocytes and a decrease in their differentiation into osteoblasts, thus forming the core of the osteogenic-lipogenic imbalance observed in osteoporosis. The bone morphogenesis protein(BMP) plays a crucial role in the regulation of the osteogenic-lipid balance in osteoporosis. This regulatory function is accomplished through both the Smad-dependent and Smad-independent pathways. This review centers on the Smad-dependent and Smad-independent pathways facilitated by BMP, offering a comprehensive overview of the potential mechanisms through which BMP-2, 4, 6, 7, and 9 contribute to the regulation of osteogenesis and lipid metabolism in osteoporosis via these pathways. In order to present novel insights for the identification of efficacious targets for clinical anti-osteoporosis medications.

Objective:To analyze the genus, drug resistance/virulence and phylogenetic characteristics of Brucella strains isolated from brucellosis surveillance sentinels in Henan Province from 2013 to 2022, and provide baseline data for the surveillance, early warning and outbreak tracing of brucellosis. Methods:Blood samples were collected from patients with Brucella infection for strain isolation, culture and species identification, drug susceptibility test, whole genome sequencing, splicing and assembly, functional/virulence/resistance gene prediction analysis and phylogenetic tree drawing based on single nucleotide polymorphism (SNP). Results:In 36 brucellosis patients, the majority were men (86.11%, 31/36), young adults aged 18-50 (88.89%, 32/36) and farmers/herdsmen (72.22%, 26/36). A total of 36 strains of Brucella melitensis were isolated, and average 1 305 functional proteins of 21 categories were predicted by strain genome; all the strains carried four main virulence factors (pmm, VirB group, BtpA/BtpB, BvrS/BvrR). The drug sensitivity rate was 100.00% to six types of antibiotics including levofloxacin, rifampicin, doxycycline, streptomycin, tetracycline and gentamicin, they showed different resistances to three antibiotics including compound trimethoprim-sulfamethoxazole, ciprofloxacin and ampicillin. The strains carried four types of resistance genes and two clusters of resistance genes, with four combinations of genotypes, the resistance mechanisms included antibiotic degradation/modification enzymes, resistant nodular cell differentiation (RND) efflux pumps, 16S/23S ribosomal rRNA binding site mutations, etc. The number of SNP differed in the genomes of 36 Brucellamelitensis strains ranged from 0 to 454 and phylogenetic tree was divided into three major branches, with relative branch distances between 0.000 0 and 0.498 6 for each strain. Conclusions:Human Brucellamelitensis strains isolated from surveillance sentinels in Henan from 2013 to 2022 carried multiple virulence and antibiotic resistance genes and had different drug resistance phenotypes. Single nucleotide polymorphism analysis and phylogenetic tree analysis showed significant differences in phylogenetic relationships among different strains.

【Objective】 To investigate the effect of isoliquiritigenin on inflammatory response of vascular endothelial cells and whether the regulatory effect of isoliquiritigenin on inflammation is mediated by histone deacetylase 3 (HDAC3). 【Methods】 Human umbilical vein endothelial cells (HUVECs) were cultured in vitro and treated with LPS, different concentrations of isoliquiritigenin and HDAC3 specific inhibitor, respectively. Real-time PCR and Western blotting were used to detect the mRNA and protein expressions of inflammatory cytokines and HDAC3. Male C57BL/6J mice were randomly divided into vehicle group and isoliquiritigenin treatment group. The vascular inflammation model of C57BL/6J mice was established by ligation of the left carotid arteries. The mRNA expressions of inflammatory cytokines and HDAC3 in the carotid arteries of mice were detected by Real-time PCR. A molecular docking study was performed to investigate the interaction between isoliquiritigenin and HDAC3. 【Results】 Compared with the vehicle group, isoliquiritigenin reduced the mRNA expressions of inflammatory cytokines NLRP3, IL-1β, IL-18, MCP-1 and ICAM-1 and decreased the expression of HDAC3 mRNA and protein in HUVECs stimulated with LPS. In addition, isoliquiritigenin also decreased the mRNA expressions of NLRP3, IL-1β and HDAC3 in carotid arteries of ligated C57BL/6J mice. The docking of isoliquiritigenin in the active site of HDAC3 showed that isoliquiritigenin might act through HDAC3. Furthermore, HDAC3 specific inhibitor RGFP966 further promoted the inhibitory effect of isoliquiritigenin on the expression of inflammatory cytokines in vascular endothelial cells. 【Conclusion】 These results suggest that isoliquiritigenin suppresses the inflammatory response of vascular endothelial cells via HDAC3.

Enteropathy-associated T cell lymphoma(EATL)is a rare subtype of mature T cell lymphoma,formerly known as EATL type Ⅰ.EATL is closely linked to celiac disease.Risk factors for EATL include a history of celiac disease,human leukocyte antigen-DQ2(HLA-DQ2)gene susceptibility,aberrant intestinal intraepithelial lymphocytes(IELs)accumulation and ulcerative jejunitis.The pathogenesis is related to HLA-DQ2 allele variation,mutational events of Janus kinase(JAK)-signal transducer and activator of transcription(STAT)pathway and nuclear factor kappa-B(NF-κ B),as well as functional changes of microRNA(miRNA).Commonly involved sites in EATL are the small intestine,followed by the stomach and colon.EATL usually presents with dyspepsia,gluten-insensitive malabsorption,intestinal obstruction,hemorrhage and perforation.EATL is an aggressive disease,with a poor prognosis.Misdiagnosis is common during the early stage of the disease.Anthracycline-based combination chemotherapy is the dominant treatment for EATL.Surgical resection is used to alleviate obstruction,hemorrhage,or perforation in some patients.Stem cell transplantation for consolidation after remission of first-line chemotherapy can prolong patients'survival time.Monoclonal antibody brentuximab vedotin targeting CD30,anti-CD52 antibody alemtuzumab,immune checkpoint inhibitors,and drugs used to treat refractory celiac disease(RCD)type Ⅱ and peripheral T cell lymphomas(PTCL)may be effective against EATL.This paper summarizes the epidemiology,genetic and molecular characteristics,clinicopathological characteristics,immunophenotypic characteristics and new advances in the treatment of EATL.

Objective:To explore the risk factors of chronic postoperative inguinal pain for laparoscopic trans-abdominal preperitoneal hernia repair and establish a nomogram prediction model for it.Methods:The clinical data of 576 patients who underwent laparoscopic trans-abdominal preperitoneal hernia repair for inguinal pain at the First Hospital of Lanzhou University from January 2015 to December 2020 were analyzed retrospectively. According to different postoperative outcomes, patients were divided into chronic pain group ( n=54) and non-chronic pain group ( n=522), compared two groups of patients in the material, including gender, age, BMI, smoking history, history of drinking, hypertension, diabetes, chronic bronchitis, abdominal surgery history, history of inguinal hernia, hernia type, the hernial sac size, prophylactic use of antibiotics, VAS score, mesh fixation techniques, operation time, length of stay. Measurement data with normal distribution were expressed as ( ± s) and independent sample t test was used for comparison between groups. Measurement data with skewed distribution were expressed as M( Q1, Q3), and the Mann-Whitney U test was used for comparision between groups. Chi-square test was used to compare the measurement data of counting data.Multivariate logistic regression was used to analyze the independent risk factors for chronic postoperative inguinal pain. R software was used to establish the drawing of the nomogram prediction model, and the consistency index, calibration chart and area under the receiver operating characteristic curve was used to evaluate the predictive ability of the nomogram prediction model. Results:According to the results of the Logistic regression analysis, age≤45 years ( OR=2.202, 95% CI: 1.080-4.491), BMI≥24 kg/m 2 ( OR=2.231, 95% CI: 1.204-4.134), hernial sac≤5 cm ( OR=2.623, 95% CI: 1.309-5.257), recurrent hernia ( OR=2.769, 95% CI: 1.118-6.860), preoperative pain ( OR=4.121, 95% CI: 2.004-8.476), suture fixation ( OR=2.204, 95% CI: 1.151-4.219)and Postoperative acute pain (VAS>3) ( OR=5.814, 95% CI: 2.532-13.350) were independent risk factors for chronic postoperative inguinal pain ( P<0.05). Based upon the above independent risk factors, the nomogram prediction model was established and verified. The area under the curve of the nomogram prediction model was 0.779 (95% CI: 0.718-0.840, P<0.01). After internal verification, the concordance index value of the prediction model was 0.779. Conclusion:age≤45 years, BMI ≥24 kg/m 2, hernial sac≤5 cm, recurrent hernia, preoperative pain, suture fixation and Postoperative acute pain (VAS>3) are independent risk factors for chronic postoperative inguinal pain for laparoscopic trans-abdominal preperitoneal hernia repair, the nomogram prediction model has a good accuracy and discrimination with a high value of clinical application.

The internal organs and meridians were associated with Yin and Yang, five elements, six qi, and time and space, based on the holistic view of heaven, earth and human, according to Huangdi Neijing. The syndrome differentiation system of six meridians and Zang Fu meridians were established by Shanghan Zabing Lun, on the basis of the three Yin, three Yang, six meridians, and five Zang system in Huangdi Neijing. We put forward the concept of the six meridians syndrome differentiation system of circular motion, considering that the six meridians syndrome differentiation system actually implies the theory of circular motion. The syndrome differentiation system was constructed with the circular model of one qi circulating around the road, rising left and falling right, corresponding up and down, and maintaining conservation in the middle as the core, integrating Yin and Yang, five elements, six qi, Zang Fu and meridians, qi, blood and body fluid, and the integration of heaven, earth and human, focusing on "disease location and disease nature", taking classical prescriptions as the main treatments, and cooperating with external treatments such as acupuncture and moxibustion. We organically combined the circular motion with the syndrome differentiation of the six meridians, systematically interpreted the physiological bases, pathological changes, progressive patterns, and the treatments, based on syndrome differentiation, by inheriting the classical thinking mode of Hetu, Luoshu,Zhouyi, Huangdi Neijing, ShennongHerbal Classic, and Shanghan Zabing Lun.

Objective:To explore and compare the reference ranges of four coagulation tests in normal pregnant women during early and late pregnancy and the influence of age.Methods:Values of four coagulation tests from 4 974 pregnant women, who gave single birth at Peking University First Hospital, Obstetrics and Gynecology Hospital of Fudan University, West China Second University Hospital, Peking University Third Hospital and Shengjing Hospital of China Medical University from February 2017 to July 2020, were measured and analyzed in this study, including prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib) and thrombin time (TT). The four normal reference ranges of coagulation during early and late pregnancy phases were expressed as P2.5- P97.5. The difference of two pregnancy phases was compared by non-parametric test of two related samples. And the difference between pregnant women of advanced and non-advanced age in the same pregnancy phase was compared by independent sample non-parametric test. Chi-square test was used to compare the incidence of pregnancy complications in different coagulation reference ranges. Results:The reference ranges of PT of normal pregnant women′s early and late pregnancy were 10.0-13.9 s and 9.6-12.3 s, the reference ranges of APTT were 22.6-35.3 s and 22.4-30.9 s, the reference ranges of Fib were 2.4-5.0 g/L and 3.0-5.7 g/L, the reference ranges of TT were 12.0-19.0 s and 11.5-18.4 s. Compared with early pregnancy, PT, APTT and TT shortened significantly, while the Fib significantly increased in late pregnancy (all P<0.001). PT, APTT and TT of advanced and non-advanced age pregnant women were significantly different (all P<0.01). Compared with the ranges of non-pregnant population, more pregnant women were included in the normal pregnant reference ranges of PT in early pregnancy and APTT in the early and late pregnancy, while the incidence of pregnancy complications had no significant differences (all P>0.05). The incidence of fetal distress was higher and the incidence of preterm birth was lower in the reference range of PT in late pregnancy. The incidence of gestational diabetes mellitus was higher in the early and late gestational Fib reference ranges, and the incidence of hypertensive disorders in pregnancy was higher in the late gestational Fib reference range (all P<0.05). Conclusions:The coagulation function of pregnant women increases significantly with the growth of pregnancy, and there is a significant difference between advanced significantly and non-advanced age pregnant women. The recommended ranges of normal pregnant women′s early and late pregnancy PT are 10.0-13.9 s and 9.6-12.3 s, the recommended ranges of APTT are 22.6-35.3 s and 22.4-30.9 s, the recommended ranges of TT are 12.0-19.0 s and 11.5-18.4 s. The appropriate ranges of normal pregnant women′s early and late pregnancy Fib still need further exploration.
