ABSTRACT

Polyphyllin I (PPI) purified from Polyphyllarhizomes displays puissant cytotoxicity in many kinds of cancers. Several researches investigated its anti-cancer activity. But novel mechanisms are still worth investigation. This study aimed to explore PPI-induced endoplasmic reticulum (ER) stress as well as the underlying mechanism in non-small cell lung cancer (NSCLC). Cell viability or colony-forming was detected by MTT or crystal violet respectively. Cell cycle, apoptosis, reactive oxygen species (ROS) and mitochondrial membrane potential were assessed by flow cytometry. Gene and protein levels were evaluated by qRT-PCR and immunoblotting respectively. Protein interaction was determined by immunoprecipitation or immunofluorescence assay. Gene overexpression or silencing was carried out by transient transfection with plasmids or small interfering RNAs. The Cancer Genome Atlas (TCGA) database was used for Gene Set Enrichment Analysis (GSEA), survival analysis, gene expression statistics or pathway enrichment assay. PPI inhibited the propagation of NSCLC cells, increased non-viable apoptotic cells, arrested cell cycle at G2/M phase, induced ROS levels but failed to decrease mitochondrial membrane potential. High levels of GRP78 indicates poor prognosis in NSCLC patients. PPI selectively suppressed unfolded protein response (UPR)-induced GRP78 expression, subsequently protected CHOP from GRP78-mediated ubiquitination and degradation. We demonstrated that the natural product PPI, obtained from traditional herbal medicine, deserves for further study as a valuable candidate for lead compound in the chemotherapy of NSCLC.

ABSTRACT

Nonalcoholic steatohepatitis (NASH) is a common clinical condition that can lead to advanced liver diseases. The mechanism of the diaease progression, which is lacking effective therapy, remains obsure. Therefore, there is a need to understand the pathogenic mechanisms responsible for disease development and progression in order to develop innovative therapies. To accomplish this goal, experimental animal models that recapitulate the human disease are necessary. Currently, an increasing number of studies have focused on natural constituents from medicinal plants which have been emerged as a new hope for NASH. This review summarized the pathogenesis of NASH, animal models commonly used, and the promising targets for therapeutics. We also reviewed the natural constituents as potential NASH therapeutic agents.

ABSTRACT

Dermatomyositis (DM) is a kind of idiopathic inflammatory myopathy characterized by chronic proximal skeletal muscle weakness and unique skin lesions. However, DM with exfoliation of esophageal mucosa is rare. A 36-year-old male patient complained of muscular soreness of extremities, dysphagia, and pharyngalgia was diagnosed with DM with exfoliation of esophageal mucosa. After treatment with glucocorticoid, immunosuppressant, acupuncture, and endoscopic submucosal dissection (ESD), the above symptoms were disappeared. During the 3-year follow-up period, the results of routine physical examination, laboratory examination, gastroscopy, and imaging examination were normal. High-dose of corticosteroid is needed in the initial treatment, but it must be reduced regularly to avoid adverse reactions. Acupuncture and ESD are also effective as adjuvant therapy.

ABSTRACT

To explore the mechanism of Shouhui Tongbian Capsules in treating constipation by means of network pharmacology and molecular docking approach. Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and Bioinfoematics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine(BATMAN) were applied to obtain chemical components and potential targets of eight herbs in Shouhui Tongbian Capsules according to the screening principles of oral availability(OB)≥30% and drug-like property(DL)≥0.18. Disease targets relating to constipation were screened out through GeneCards, PharmGkb and other databases, drug targets were integrated with disease targets, and intersection targets were exactly the potential action targets of Shouhui Tongbian Capsules for treating constipation; PPI network of potential targets was constructed using STRING platform, and GO(gene ontology) analysis and KEGG(Kyoto encyclopedia of genes and genomes) pathway data were obtained to conduct enrichment analysis and predict its mechanism of action. Cytoscape 3.6.1 was used to construct a network of "medicinal materials-chemical components-drug targets", and the network topology analysis was carried out on the PPI network to obtain its main components and key targets. Molecular docking between components and key targets of Shouhui Tongbian Capsules verified the accuracy of network pharmacological analysis results. The PPI network analysis showed 92 chemical components, including quercetin, stigmaste-rol, aloe-emodin, rhein, and key targets for instance AKT1, MAPK1, IL6, JUN, TNF and TP53. The enrichment analysis of KEGG screened out 157 signal pathways(P<0.01), mainly involving interleukin 17 signaling pathway, AGE-RAGE signaling pathway in diabetic complications, thyroid hormone signaling pathway. Quercetin, resveratrol and lysine with top degree value had a rational conformation in docking site of protein crystal complexes. This study preliminarily showed that various active ingredients in Shouhui Tongbian Capsules could regulate multiple signaling pathways, increase intestinal smoothness and peristalsis function, ensure smooth intestinal lumen, and play a role in treating constipation by acting on key targets, such as AKT1, MAPK1, IL6 and JUN.

ABSTRACT

Dyslipidemia is a disease of lipid metabolism. At present, the prevalence of dyslipidemia in adults in China is as high as 40.40%. In the United States, there are more than 100 million individuals with abnormal low-density lipoprotein cholesterol (LDL-C), and the incidence rate is increasing year by year and showing a trend of becoming younger. Dyslipidemia is closely related to a variety of diseases such as fatty liver, atherosclerosis , hypertension, coronary heart disease, diabetes, and stroke. It has now developed into a global public health problem that seriously threatens human life and health. Modern medicine believes that its pathogenesis is complicated and is related to abnormal glucose and lipid metabolism, insulin resistance (IR) and other factors. Chinese medicine ascribes it to primary asthenia-secondary sthenia syndrome, which is closely related to the liver, spleen, and kidney. It is believed that excessive fat and grease can cause phlegm and cause many diseases. In terms of its treatment, western medicine mainly uses statin chemical synthesis preparations, with stable therapeutic effect, but many adverse reactions such as myalgia, myositis, rhabdomyolysis and acute renal injury are the main factors restricting its clinical application. Traditional Chinese medicine (TCM) has a long history, and multi-pathway, multi-target, multi-level regulation of dyslipidemia, few adverse reactions and low drug dependence are the principal advantages of TCM in treating dyslipidemia. At present, there are more and more researches on the prevention and treatment of dyslipidemia by TCM, but they are mainly focused on the observation of curative effect and the summary of prescription, and there are relatively few in-depth discussion and summary of the mechanism of TCM. Through comprehensively retrieving and collating the relevant domestic and foreign literatures in the past five years, we reviews from the perspective of effective ingredients, therapeutic pathways, and targets of action, and comprehensively introduces the latest research progress of TCM on the mechanism of regulating dyslipidemia, and put forward some suggestions for the possible research direction in the future, in order to provide new ideas and theoretical basis for TCM in clinical prevention and treatment of this disease.

ABSTRACT

Resuscitative endovascular balloon occlusion of the aorta(REBOA) is an important technical method for early anti-shock. It can quickly achieve effective hemostasis, maintain basic blood pressure, ensure blood supply to important organs such as the brain, and improve the success rate of anti-shock treatment. However, the use of REBOA is limited because it can cause complications such as severe distal ischemia. With the improvement of clinical awareness and the continuous improvement of anti-shock treatment concept, REBOA has made significant progress, including the use of pREBOA and iREBOA, and the use in cardiac arrest. In order to make better use of REBOA, further in-depth research is needed to establish a comprehensive medical treatment system and training system to maximize its role.

ABSTRACT

Objective:To observe the epidemiological characteristics of spinal metastases by retrospectively analyzing the medical records of multicenter spinal metastases in China.Methods:Patients with spinal metastases were identified from several clinical centers between January 2007 and July 2019. A total of 1 976 patients were included in this study, including 1 129 males (57.14%) and 847 females (42.86%). The mean age was 58.6±11.6 years (range 13-92 years). The demographic characteristics, primary tumor types, spinal involvement of each patient were summarized and their clinical indicators were obtained by consulting medical records, including: Frankel grade, visual analog scale (VAS), metastatic spinal cord compression (MSCC), Tokuhashi revised score, the spinal instability neoplastic score (SINS), Karnofsky performance status (KPS), and history of malignant tumors. Finally, the intervention influencing factors of patients undergoing surgical treatment were statistically analyzed.Results:The ratio of male to female in 1 976 spinal metastases was 1.33∶1. The median age was 59.0, and most patients (63.71%) were in the ages range of 50-69. The average age of female was younger than male, and the difference was statistically significant. The proportion of male patients over 60 years old was higher than females, and the difference was statistically significant. The most common primary tumor was lung cancer (n=730, 36.94%), followed by unknown origin (n=326, 16.50%), breast cancer (n=159, 8.05%), kidney cancer (n=120, 6.07%), gastrointestinal cancer (n=109, 5.52%), etc. The most common primary tumor was lung cancer in both males and females, followed by unknown origin in males and breast cancer in females. In the past 10 years, the proportion of unknown origin has decreased, and the proportion of breast cancer has increased. According to the Tomita score, 1 284 patients (64.98%) were rapid growth tumors, 211 patients (10.68%) were moderate growth tumors, and 481 patients (24.34%) were slow growth tumors. There were 730 patients (57.14%) in the subgroup of the number<3, the most level of which was lumbar vertebrae, with 368 patients (32.60%). The remaining 847 patients (42.86%) were included in the subgroup of the number≥3, the most level of which was multiple-level of spine, with 617 patients (72.85%). Among the 1 976 patients, spinal cord injury occurred in 50.76% of patients, in which 77.18% of patients developed moderate and above pain, 14.02% of patients appeared metastatic spinal cord compression, and only 28.95% of patients had a clear history of primary tumor. In terms of treatment, 34.92% of patients underwent surgery, 5.97% underwent radiotherapy on spinal metastases, 6.02% underwent chemotherapy, and 1.77% underwent targeted therapy. Preoperative Frankel grade, SINS, and Tokuhashi revised score were important factors affecting the surgical treatment of patients.Conclusion:This study describes the epidemiological characteristics of multicenter spinal metastases in detail, which could assist orthopedic surgeons to understand the clinical characteristics of spinal metastases and was of great significance on guiding the clinical diagnoses and scientific researches.

ABSTRACT

Objective:To determine the gender and age differences in anatomical parameters of proximal femur in middle-aged and elderly patients with femoral intertrochanteric fracture so as to provide theoretical evidence for development of internal fixation devices.Methods:The clinical and CT data of 375 patients with intertrochanteric fracture were analyzed retrospectively who had been treated at Department of Orthopedics, The First Medical Center, General Hospital of Chinese PLA from September 2009 to March 2017. The patients were divided into 4 age groups. The middle-aged group (from 45 to 59 years old) had 22 cases, 16 males and 6 females; the early elderly group (from 60 to 74 years old) had 87 cases, 37 males and 50 females; the elderly group (from 75 to 89 years old) had 238 cases, 76 males and 162 females; the late elderly group (≥90 years old) had 28 cases, 6 males and 22 females. The anteversion angle of femoral neck, femoral neck-shaft angle, femoral head diameter, femoral neck length, femoral neck offset and femoral neck width were measured on their images. The anatomical parameters of proximal femur were compared between genders in the same age group and between groups of the same gender.Results:There were no significant differences between male and female patients with femoral intertrochanteric fracture in body mass index or AO classification, showing comparability( P>0.05). The anteversion angle of femoral neck (8.33°±5.00°) of the male middle-aged and elderly patients with intertrochanteric fracture was significantly smaller than that of the female ones (11.28°±6.15°), but their femoral head diameter, femoral neck length, femoral neck offset and femoral neck width (49.10 mm±2.48 mm, 99.70 mm±5.22 mm, 7.18 mm±2.20 mm and 39.10 mm±4.92 mm) were significantly larger than those of the female ones (43.46 mm±2.79 mm, 90.00 mm ± 4.75 mm, 6.29 mm±2.07 mm and 33.49 mm±4.87 mm) (all P<0.05). The femoral head diameter, femoral neck length and femoral neck width of the male patients in all the 4 age groups were significantly larger than those of the female ones ( P< 0.05). The anteversion angles of femoral neck of the male patients in the early elderly, elderly and late elderly groups were significantly smaller than those of the female ones ( P< 0.05). The femoral neck offset of male patients in the elderly group was significantly greater than that of female ones ( P< 0.05). There were no statistically significant differences in anteversion angle of femoral neck, femoral neck-shaft angle, femoral head diameter, femoral neck length, femoral neck offset or femoral neck width between groups of the same gender ( P>0.05). Conclusions:Compared with the middle-aged and elderly male patients with femoral intertrochanteric fracture, the middle-aged and elderly female ones have a larger anteversion angle of femoral neck, smaller offset, width and length of femoral neck, and a smaller femoral head diameter. There are no significant age differences in anatomical parameters of the proximal femur in middle-aged and elderly patients with femoral intertrochanteric fracture.

ABSTRACT

Objective:To compare the effect and reproductive prognosis of hysteroscopic electroresection of intrauterine adhesions and mechanical separation in the treatment of moderate and severe intrauterine adhesions (IUA).Methods:A retrospective case-control study was conducted to analyze the clinical data of 116 cases of moderate and severe intrauterine adhesions treated by transcervical resection of adhesions(TCRA) in Guangzhou First People′s Hospital from February 2015 to January 2017.According to the different operation methods and condition of the patients, 116 patients were divided into mechanical group (54 cases) and treated with hysteroscopic mechanical separation, including 41 cases of American Fertility Society (AFS) classification of moderate and 13 cases of severe; ; 62 cases of electric resection group were treated with electrosurgical separation, including 47 cases of moderate AFS classification and 15 cases of severe AFS.The operation time, intraoperative bleeding volume, one-time success rate, postoperative cervical morphology, menstrual recovery and pregnancy outcome were compared between the two groups.Results:The operation time of severe patients in mechanical group ((31.56±4.37) min), electrotomy group ((23.73±4.27) min) was longer than that of moderate patients ((27.56±4.37) min and (20.35±4.11) min). The intraoperative bleeding volume in mechanical group ((16.24±4.74) ml) and electrotomy group ((12.56±4.26) ml) was higher than that of moderate patients ((13.87±4.42) ml and (9.57±4.35) ml), the difference was statistically significant (t values were 2.981, 3.214, 3.014, 4.011, P values were 0.005, 0.006, 0.005, <0.001). Meanwhile, the moderate and severe operation time of mechanical group was longer than that of electrosurgical group, and the intraoperative blood output was more than that of electrosurgical group (t values were 5.245, 4.742, 4.591, 4.347, all P<0.001). The total effective rate of uterine cavity morphology was 100% (41/41, 47/47) in the two groups, which was higher than that in the severe group (9 cases in the mechanical group, 10 cases in the electrotomy group, χ 2=12.304, χ 2=15.615, all P<0.001). The total effective rate of menstrual recovery in the mechanical group was 95.12% (39/41) higher than that in the severe group (4 cases), and 78.72% (37/47) in the electrotomy group, (χ 2=14.347, χ 2=5.100, P<0.001, P=0.025). In the electrotomy group, the effect of menstrual recovery was 78.72% (37/45) higher than that in the severe group(5 cases), (χ 2=11.554, P<0.001). The required fertility rate (95.12% (39/41) in the mechanical group, 95.74% (45/47) in the electrosurgical group), the successful pregnancy rate(69.23% (27/41) in the mechanical group, 68.89% (31/47) in the electrosurgical group), the live birth rate (70.37% (19/41) in the mechanical group, 70.97% (22/47) in the electrosurgical group) and the full-term birth rate (51.85% (14/27) in the mechanical group and 51.61% (16/31) in the electrosurgical group) were higher than those in the severe patients (the mechanical group: 10 cases, 4 cases, 1 case, 0 case; the electrotomy group: 11 cases, 4 cases, 1 case, 0 case, χ 2 values were 4.087, 5.332, 4.111, 3.996, 4.334, 4.658, P values were 0.047, 0.015, 0.042, 0.046, 0.033, 0.027, 0.044, 0.042). The placental adhesion rate during labor (22.22% (6/27) in mechanical group, 22.58% (7/31) in electrosurgical group) and placental implantation rate (7.41 (2/31) in mechanical group and 6.45% (2/35) in electrosurgical group) were lower than those in severe patients (2 cases and 1 case in mechanical group, 2 cases and 1 case in electrosurgical group, P values were 0.043, 0.037, 0.045, 0.04). Conclusion:Hysteroscopic resection of moderate and severe intrauterine adhesions and mechanical separation have good curative effect on moderate and severe IUA patients.The operation mode can be reasonably selected according to the actual situation of the hospital and patients.

Objective:To investigate the normal range of exhaled nitric oxide (FeNO) in 6-18-year-old children in China, so as to provide a data base for the establishment of FeNO standards for Chinese children.Methods:A multi-center study was conducted on 5 949 children aged 6-18 (3 101 males and 2 848 females) in 16 pro-vinces of 7 administrative districts in China.According to the technical standard recommended by American Thoracic Society/European Respiratory Association, FeNO was measured, and the relationship of FeNO with the sex, age, height, weight, body mass index and region was discussed.Results:The geometric mean FeNO value of Chinese children aged 6-18 was 14.1 ppb, and its 95% confidence interval (skewness distribution) was 1.0-38.2 ppb.The geometric mean FeNO values of children aged 6-11 and 12-18 were 13.1 ppb and 15.7 ppb, respectively, and their 95% confidence intervals (skewness distribution) were 1.0-38.1 ppb and 2.0-38.2 ppb.For children at and under 11 years old, FeNO decreased with age, with a mean decline of 1 ppb per year.The multiple linear regression results suggested that there was a significant correlation between FeNO and age for children aged 6-11, and FeNO of children aged 12-18 was significantly correlated with the gender, height, and region(all P<0.01). Conclusions:FeNO values of Chinese children and adolescents in this study are higher than those obtained by the previous study conducted from 2010 to 2012.For children aged 12-18, 16 ppb is recommended as the clinical cut-off point.For children at or under 11 years old, the influence of age on FeNO should be considered, and the cut-off point of FeNO decreases by 1 ppb as the age is reduced by one year.

ABSTRACT

ObjectiveTo investigate the effect of kaempferol on the proliferation, migration, invasion, and apoptosis of human hepatoma Bel-7402 cells and related molecular mechanism. MethodsHepatoma Bel-7402 cells cultured in vitro were randomly divided into control group and low-, middle-, and high-concentration experimental groups. The experimental groups were treated with low-, middle-, and high-concentration kaempferol (25, 50, and 100 μmol/L), and the control group was treated with an equal volume of dimethyl sulfoxide. CCK-8 assay was used to observe the effect of kaempferol on the viability of Bel-7402 cells; plate colony formation assay was used to evaluate the effect of kaempferol on cell colony formation ability; wound healing assay and Transwell chamber were used to observe the effect of kaempferol on cell migration and invasion; Western blot was used to measure the expression of apoptosis- and cycle-related proteins. A one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsAfter 24 hours of treatment, the cell viability was 100.00%±2.72% in the control group and 75.70%±2.42%, 62.79%±2.45%, and 43.41%±2.11%, respectively, in the low-, middle-, and high-concentration experimental groups, and compared with the control group, the experimental groups had a significant reduction in cell viability (all P<0.05). The number of cell colonies was 923.3±35.2 in the control group and 682.7±24.4, 464.0±22.0, and 327.3±14.0, respectively, in the low-, middle-, and high-concentration experimental groups, and compared with the control group, the experimental groups had a significant reduction in cell colony formation ability (all P<0.05). After 24 hours of treatment, the relative migration rate was 100.00%±1.11% in the control group and 63.33%±1.16%, 51.72%±3.23%, and 37.18%±2.71%, respectively, in the low-, middle-, and high-concentration experimental groups, and the number of transmembrane cells was 212.0±3.0 in the control group and 134.0±2.0, 71.0±2.0, and 34.0±1.0, respectively, in the low-, middle-, and high-concentration experimental groups; compared with the control group, the experimental groups had significant reductions in relative migration rate and number of transmembrane cells (all P<0.05). After 48 hours of treatment, compared with the control group, the low-, middle-, and high-concentration experimental groups had a significant reduction in the expression of the anti-apoptotic protein Bcl-2 (all P<0.05), a significant increase in the expression of the pro-apoptotic protein Bax (all P<0.05), and a significant reduction in the expression of C<italic/>yclinD1 (all P<005). ConclusionKaempferol can inhibit the proliferation, migration, and invasion of human hepatoma Bel-7402 cells and promote the apoptosis of such cells, possibly by regulating the apoptosis proteins Bax and Bcl-2 and downregulating the expression of CyclinD1.
