ABSTRACT

OBJECTIVES@#To explore the optimal maintenance dose of caffeine citrate for preterm infants requiring assisted ventilation and caffeine citrate treatment.@*METHODS@#A retrospective analysis was performed on the medical data of 566 preterm infants (gestational age ≤34 weeks) who were treated and required assisted ventilation and caffeine citrate treatment in the neonatal intensive care unit of 30 tertiary hospitals in Jiangsu Province of China between January 1 and December 31, 2019. The 405 preterm infants receiving high-dose (10 mg/kg per day) caffeine citrate after a loading dose of 20 mg/kg within 24 hours after birth were enrolled as the high-dose group. The 161 preterm infants receiving low-dose (5 mg/kg per day) caffeine citrate were enrolled as the low-dose group.@*RESULTS@#Compared with the low-dose group, the high-dose group had significant reductions in the need for high-concentration oxygen during assisted ventilation (P=0.044), the duration of oxygen inhalation after weaning from noninvasive ventilation (P<0.01), total oxygen inhalation time during hospitalization (P<0.01), the proportion of preterm infants requiring noninvasive ventilation again (P<0.01), the rate of use of pulmonary surfactant and budesonide (P<0.05), and the incidence rates of apnea and bronchopulmonary dysplasia (P<0.01), but the high-dose group had a significantly increased incidence rate of feeding intolerance (P=0.032). There were no significant differences between the two groups in the body weight change, the incidence rates of retinopathy of prematurity, intraventricular hemorrhage or necrotizing enterocolitis, the mortality rate, and the duration of caffeine use (P>0.05).@*CONCLUSIONS@#This pilot multicenter study shows that the high maintenance dose (10 mg/kg per day) is generally beneficial to preterm infants in China and does not increase the incidence rate of common adverse reactions. For the risk of feeding intolerance, further research is needed to eliminate the interference of confounding factors as far as possible.

ABSTRACT

OBJECTIVE@#To observe clinical efficacy of chiropractic manipulation in the treatment of degenerative scoliosis (DS).@*METHODS@#From June 2017 to September 2019, 120 patients with degenerative scoliosis were randomly divided into treatment group (60 cases) and control group(60 cases). The patients in treatment group were treated with chiropractic manipulation once every other day for 4 weeks. The patients in control group were treated with eperisone hydrochloride tablets combined with thoracolumbar orthopedic(TSLO)brace, oral eperisone hydrochloride tablets 50 mg three times a day, wearing TSLO brace for not less than 8 hours a day. The course of treatment was 4 weeks. After the patients were selected into the group, visual analogue scale (VAS) and Oswestry Disability Index (ODI) were recorded before treatment, 1, 2, 3, 4 weeks after treatment and 1 month after treatment. The full length X-ray of the spine was taken before and 4 weeks after treatment, and the scoliosis Cobb angle, sagittal vertical axis (SVA) and lumbar lordosis (LL) were measured and compared. The adverse reactions during the treatment were recorded.@*RESULTS@#There were significant differences in VAS and ODI between two groups at each time point after treatment (P<0.001), VAS and ODI at 2 weeks after treatment (PVAS=0.025, PODI=0.032) and 3 weeks after treatment(PVAS=0.040, PODI=0.044) in treatment group were significantly different from those in control group, but there was no significant difference in VAS and ODI at other time points between treatment group and control group (P>0.05). There was significant difference in Cobb angle between treatment group(P=0.010) and control group(P=0.017) after treatment, but there was no significant difference in LL and SVA between treatment group and control group. There was no significant difference in Cobb angle, LL and SVA between two groups before and after treatment. During the treatment, there were 4 mild adverse reactions in the control group and no adverse reactions in the treatment group.@*CONCLUSION@#Chiropractic manipulation can effectively relieve pain and improve lumbar function in patients with degenerative scoliosis. The onset of action is faster than that oral eperisone hydrochloride tablets combined with TSLO brace, and it has better safety and can improve Cobb angle of patients with degenerative scoliosis.

ABSTRACT

Background/Aims@#We aimed to study the clinical characteristics, treatment modality, and the prognosis of synchronous multiple primary esophageal squamous cell carcinomas (SMPESCC). @*Methods@#A total of 117 SMPESCC cases were evaluated retrospectively from 2010 to 2015. @*Results@#The most common locations of SMPESCC were mid- and lower thoracic segments (n = 208, 84.9%). The 1-, 2-, and 3-year overall survival rates were 53.8%, 30.8%, and 15.4%, respectively; the median survival time (MST) was 12.5 months. With definitive radiotherapy and surgery, respectively, the MST of stage I/II patients were 34.2 and 26.7 months, of stage III patients were 8.3 and 13.2 months (p = 0.163), and of stage IV patients were and 8 and 12.6 months (p = 0.379). Clinical stage, family history of cancer, and Karnofsky performance status were independent prognostic factors for the whole cohort by Cox multivariate regression analysis (hazard ratio [HR] = 0.859, p < 0.001; HR = 0.579, p = 0.032; and HR = 0.586, p = 0.013). @*Conclusions@#Although the prognosis of SMPESCC is poor, stage I/II patients can achieve long-term survival with aggressive treatment, especially those with a Karnofsky performance score 90 or higher and who have no family history of cancer. Definitive radiotherapy could achieve a similar survival rate to definitive surgery at different clinical stages.

ABSTRACT

Objective:To establish a mouse model of the abdominal aortic aneurysm by elastase perfusion and to provide a reference for the study of the mechanism related to abdominal aortic aneurysm formation.Methods:AAAs were induced by porcine pancreatic elastase (PPE) infusion in male C57BL/6 mice. The control group was perfused with normal saline (Saline). The changes in abdominal aortic diameter were compared at 14 days after perfusion. The diameter of the abdominal aorta stained with HE was measured. The destruction of the elastic plate in the abdominal aortic wall was observed by elastic plate staining. TUNEL assay was used to evaluate the apoptosis in aneurysm tissues.Results:Porcine pancreatic elastase (PPE) perfusion successfully established the mouse model of abdominal aortic aneurysm, in which an aneurysm formation rate was 100% at 14 days after the operation. After modelling, the abdominal aorta diameter in the mouse was significantly increased, higher than that in the control group perfused with normal saline ( P<0.05). In the PPE group, the elastic plate of the aortic wall was straightened and thinned, and interrupted. The proportion of TUNEL-positive cells in the PPE group was significantly higher than that in the control group perfused with normal saline ( P<0.05). Conclusion:Elastase perfusion can stably establish the abdominal aortic aneurysm model, and we observe the destruction of the elastic plate in the medial layer of the abdominal aortic wall and the up-regulation of the apoptosis process in the model. It provides a reference to study the pathogenesis of abdominal aortic aneurysm further.

ABSTRACT

Coal miners are a high-risk occupational group of work-related musculoskeletal disorders(WMSDs). This disease not only causes a reduction in the quality of life of workers, loss work ability, and decline in work efficiency, but also becomes an important factor leading to increase social medical burden. At present, most of the evaluation of WMSDs of coal miners at home and abroad adopts the international general scale. Chinese scholars have developed a WMSDs questionnaire that meets the occupational characteristics of Chinese population based on the international general scale—the Chinese Musculoskeletal Disorders Questionnaire. The questionnaire has good reliability and validity, and is a reliable and effective tool for evaluating WMSDs. The prevalence of WMSDs in coal miners is relatively high. The occupational factors that affect WMSDs in coal miners are mainly physical load, postural load, mental load, work organization, and work environment. The individual factors are mainly age, working experience, and education level. It′s recommended to prevent and control the occurrence of coal miners′ WMSDs through multi-level intervention measures such as strengthening education, changing the working posture, and improving the working conditions of coal miners, and rationally arranging labor organizations.

ABSTRACT

Objective:To explore the effects of clinical characteristics and dosimetric factors on the survival and prognosis of patients with locally advanced thoracic esophageal squamous cell carcinoma after concurrent chemoradiotherapy (CCRT).Methods:A total of 158 patients with locally advanced thoracic esophageal squamous cell carcinoma undergoing CCRT in Shandong Cancer Hospital, Anyang Cancer Hospital of Henan Province, Tengzhou Central People′s Hospital of Shandong Province and the First Affiliated Hospital of China Medical University from August 2015 to October 2018 were selected as the research subjects. These patients were divided into standard-dose group (50.0-50.4 Gy, n=59) and high-dose group (>50.4 Gy, n=99) according to the radiotherapy dose. The overall survival (OS) and progression-free survival (PFS) of the two groups after treatment were compared. Kaplan-Meier method was used to calculate survival rate and survival comparison was performed by log-rank test. Cox proportional hazard regression model was used to analyze the adverse prognostic factors. The receiver operating characteristic (ROC) curve was used to analyze the predictive value of lung V 30 for patient prognosis. Results:In 158 patients with locally advanced esophageal squamous cell carcinoma, 19 cases (12.03%) had complete remission after CCRT, 103 cases (65.19%) had partial remission, 27 cases (17.09%) had stable disease, 9 cases (5.70%) had progression disease, and the total effective rate was 77.22%. The median OS of 158 patients was 41 months (95% CI: 25-57 months), and the 1- and 3-year OS rates were 76% and 51%, respectively. The median PFS was 24 months (95% CI: 13-35 months), and the 1- and 3-year PFS rates were 60% and 39%, respectively. The 1- and 3-year OS rates in the standard-dose group were 74% and 56%, and those in the high-dose group were 77% and 49%, with no statistically significant difference ( χ2=0.300, P=0.584). The 1- and 3-year PFS rates in the standard-dose group were 62% and 37%, and those in the high-dose group were 59% and 40%, with no statistically significant difference ( χ2<0.001, P=0.990). Univariate analysis showed that the length of the lesion, N stage, clinical stage, short-term efficacy of CCRT, planning target volume (PTV) D max, gross tumor volume (GTV) D mean, V 5, V 10, V 20, V 30, D mean of the left, right and bilateral lung were all the prognostic factors for OS and PFS (all P<0.05). Multivariate analysis showed that the length of the lesion ( HR=2.226, 95% CI: 1.244-3.985, P=0.007), N stage ( HR=2.819, 95% CI: 1.137-6.991, P=0.025), clinical stage ( HR=1.897, 95% CI: 1.079-3.334, P=0.026), short-term efficacy of CCRT ( HR=1.805, 95% CI: 1.250-2.606, P=0.002), left lung V 10 ( HR=0.811, 95% CI: 0.668-0.986, P=0.035), left lung V 30 ( HR=0.617, 95% CI: 0.408-0.933, P=0.022), right lung V 20 ( HR=2.067, 95% CI: 1.010-4.231, P=0.047), bilateral lung V 10 ( HR=1.299, 95% CI: 1.016-1.662, P=0.037) and bilateral lung V 30 ( HR=2.368, 95% CI: 1.142-4.910, P=0.021) were independent prognostic factors affecting OS. N stage ( HR=2.433, 95% CI: 1.201-4.931, P=0.014), short-term efficacy of CCRT ( HR=2.067, 95% CI: 1.391-3.071, P<0.001) and bilateral lung V 30 ( HR=0.113, 95% CI: 0.018-0.719, P=0.021) were independent prognostic factors affecting PFS. The ROC curve for predicting OS and PFS showed that the optimal cut-off value of bilateral lung V 30 was 9.5%. Conclusion:Compared with the standard-dose group, increasing the dose of radiotherapy fails to improve the long-term survival of patients with locally advanced thoracic squamous cell carcinoma. Lesion length, N stage, clinical stage, short-term efficacy of CCRT, left lung V 10 and V 30, right lung V 20 , bilateral lung V 10 and V 30 are independent prognostic factors for OS in patients with locally advanced thoracic squamous cell carcinoma. N stage, short-term efficacy of CCRT and bilateral lung V 30 are independent prognostic factors for PFS. When bilateral lung V 30≤9.5%, the patients′ OS and PFS will benefit from the treatment.

ABSTRACT

By systematically sorting out the ancient medical books and modern clinical literature of Yiguanjian, the historical evolution of this formula, including its source, composition, origin, processing, dosage, preparation and usage, functions and indications, evolution of prescription meaning, is textual so as to clarify the historical evolution and clinical application of Yiguanjian. On the basis of fully considering the actual demand of development of famous classical formula preparation and the usage habit of modern clinical practice, the feasible development suggestions were put forward. Yiguanjian is composed of six herbs, which is derived from Yifang Jiedu (《医方絜度》) . It is an ancient book of traditional Chinese medicine edited by QIAN Min-jie in Qing dynasty. The original medicinal plants and medicinal parts of the formula were basically the same as those recorded in the 2020 edition of Chinese Pharmacopoeia. The raw products should be selected for decoction pieces and processed according to the methods recorded in the 2020 edition of Chinese Pharmacopoeia. The reference dose of the medicine in this formula is set out in Yifang Jiedu. According to dosage of one Qian(钱)=3.73 g, the dosages of Glehniae Radix, Ophiopogonis Radix and Angelicae Sinensis Radix were 5.60 g, the dosages of Lycii Fructus and Rehmanniae Radix were 11.19 g, the dosage of Toosendan Fructus was 7.46 g. These decoction pieces were boiled and warm decoction was taken. According to ancient medical records, the formula always has the effect of nourishing Yin and relieving Qi of liver. It is used to treat syndrome of stagnation of liver-Qi and deficiency of liver-Yin and kidney-Yin, which can be seen with pain in chest, stomach and flank, acerbity and vomiting, dry throat and mouth, red tongue, weak pulse or deficiency of string and hernia. Here, the source, processing and others of Yiguanjian were clarified, providing a literature reference for the development and application of this famous classical formula.

ABSTRACT

Objective:Phthalates (PAEs) are common environmental endocrine disruptors. In this study, the effects of oxidative stress on liver and nutrient metabolism were determined in male diabetic rats exposed to di-2-ethylhexyl phthalate (DEHP), and the mechanism of DEHP toxicity was explored. Methods:Thirty-two SPF male Wistar rats aged five weeks, weighing 150-170 g, were fed adaptively for one week to establish the model of type 2 diabetes. The model was established by intraperitoneal injection of streptozotocin (STZ) (25 mg/kg) after feeding with high sugar and high fat diet for four weeks. Second STZ injection was given two days later. The model was considered to be established successfully when the random blood glucose level was found to be higher than 16.7 mmol/L in two separate tests. Twenty diabetic rats were then randomly divided into four groups, including control group (corn oil), 100, 300 and 900 mg/kg DEHP groups. The rats were treated with DEHP by gavage (5 mL/kg) once a day for 30 days. They were fed with normal diet during the treatment period. Caudal venous blood was collected on the 1st, 14th, and 28th days to measure the random blood glucose level. The changes of glucose tolerance were determined by oral glucose tolerance test on the 29th day. Fasting blood glucose (FPG) was measured on the next day of the last exposure. After the rats were anesthetized with pentobarbital and killed, the liver was weighed, the liver coefficient was calculated and the liver pathological section was made. Blood was taken from the abdominal aorta. The levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), triacylglycerol (TG) and albumin (ALB) in serum were measured by spectrophotometry, and the levels of insulin, glutathione (GSH), H2O2, malondialdehyde (MDA) and superoxide dismutase (SOD) in fasting serum were measured by radioimmunoassay. Results:There was no significant difference in body weight and random blood glucose in the type 2 diabetic rats exposed to different concentrations of DEHP (all P>0.05). At each time point of the glucose tolerance curve, the blood glucose value of the exposure groups was higher than that of the control group. A "false plateau period" appeared after the blood glucose value reached or exceeded the upper limit at 15 minutes, and the blood glucose level in each group was higher than that of the control group at 120 minutes. The liver organ coefficient of 300 and 900 mg/kg DEHP groups was higher than that of the control group (both P<0.01), and the liver organ coefficient was positively correlated with the exposure concentration of DEHP (r=0.80,P<0.000 1). Under the microscope, the liver cells in diabetic rats were swollen, the cytoplasm was light stained, and there were vacuoles in the cells. The serum ALP level in diabetic rats of 900 mg/kg DEHP group was significantly higher than that in the control group (P<0.01). The serum ALP level was positively correlated with the concentration of DEHP (r=0.75, P<0.01). The serum MDA level in diabetic rats of 300 mg/kg and 900 mg/kg DEHP groups was significantly higher than that of the control group (both P<0.01), and the serum MDA level was positively correlated with the concentration of DEHP (r=0.84, P<0.000 1). The serum SOD level of 900 mg/kg DEHP group was significantly higher than that of control group (P<0.01). Conclusion:DEHP exposure could lead to liver damage, abnormal glycolipid metabolism, and increase the level of oxidative stress and antioxidant level in male diabetic rats, but did not show a significant effect on insulin resistance.

ABSTRACT

Objective To investigate the effectiveness and cost of 50% and 80% wettable powder of niclosamide ethanolamine salt (NESWP) and 26% metaldehyde and niclosamide suspension concentrate (MNSC) in hilly schistosomiasis-endemic regions, so as to provide insights into the selection of chemical molluscicides in hilly regions. Methods In September 2020, a wasteland in Guanshanqiao Village, Yanrui Township, Yushan County of Jiangxi Province was selected as the experimental region, which was sectioned into five blocks and defined as four experimental groups (A1, A2, B, C) and a blank control group (D). 80% NESWP were given at doses of 1 g/m2 and 1.5 g/m2 in groups A1 and A2 using the spraying method, 50% NESWP was given at a dose of 2 g/m2 in Group B using the spraying method, and 26% MNSC was at a dose of 4 g/m2 in Group C using the spraying method, while no chemical treatment was given in Group D. Snail survey was performed using a systematic sampling method before chemical treatment and 1, 3, 7 d and 15 d post-treatment to examine the molluscicidal effect, and all molluscicidal costs were estimated to calculate the cost of chemical treatment per 1 m2 and the cost of the reduction in the mean density of living snails per 1%. Results The highest mortality of snails was 78.95% and the lowest density of living snails was 0.2388 snails/0.1 m2 in the experimental groups within 7 d of chemical treatment, and the highest mortality of snails was 94.74% and the lowest density of living snails was 0.058 0 snails/0.1 m2 7 d post-treatment. There were no significant differences in the snail mortality among the A1, A2, B and C groups 1 (χ2 = 2.250, P > 0.05), 3 (χ2 = 1.779, P > 0.05) or 15 d post-treatment (χ2 = 2.286, P > 0.05), while a significant difference was detected in the snail mortality among the four groups 7 d post-treatment (χ2 = 7.990, P = 0.046). In addition, there were no significant differences in the snail mortality between A1 and A2 groups 1 (χ2 = 0.724, P > 0.05), 3 (χ2 = 0.584, P > 0.05), 7 (χ2 = 0.400, P > 0.05) or 15 d post-treatment (χ2 = 0.251, P > 0.05). The costs of chemical treatment per 1 m2 were 0.58, 0.60, 0.64 Yuan and 0.73 Yuan in groups A1, A2, B and C, and the costs of the mean density of living snail per 1% reduction were 19.29, 20.44, 21.68 Yuan and 23.53 Yuan in groups A1, A2, B and C, respectively. Conclusion 80% NESWP shows a high molluscicidal efficacy and low cost in hilly schistosomiasis-endemic regions.

ABSTRACT

Objective:To study the association between metabolic syndrome (MS) and Chinese healthy eating index (CHEI), and to identify the beneficial or adverse effects of diets on MS in a community population of Shanghai. Methods:Based on the inclusion and exclusion criteria, the data of 4 856 subjects from a community in Shanghai was collected by interview. Total CHEI score and its component score were calculated based on the frequency of food consumption. Physical examination and blood biochemical tests were used to diagnose MS. The logistic regression model was used to analyze the relationship between MS or relative indexes and the total CHEI score or its component score. Results:The study showed the overall prevalence of MS was 24.71%. There were significant differences between MS group and controls (P<0.05) in age, BMI, waist circumference, fasting blood glucose, triglycerides, total cholesterol, systolic blood pressure, diastolic blood pressure, glycated hemoglobin, high-density lipoprotein and energy intake. After adjusting for potential confounders, it showed that the higher total CHEI score, the lower risk of central obesity, increased diastolic blood pressure, increased glycated hemoglobin, hyperglycemic and MS (P<0.05). The increase in component score of potatoes, milk, beans, dark vegetables, fruits, oil and sodium reduced risk of obesity, hypertension, hyperglycemia, dyslipidemia and MS (P<0.05). Conclusion:The quality of healthy diet (CHEI score more than 80) and increased intake of specific dietary components (potatoes, milk, beans, dark vegetables, fruits) reduce the risk of MS effectively.

ABSTRACT

Since July 2020, nucleic acids of novel coronavirus SARS-CoV-2 were frequently detected in cold chain food imported to China, making imported food being a potential risk to the COVID-19 outbreak. Based on the epidemiological characteristics of SARS-CoV-2, imported cold-chain food and their packaging may become the carriers of SARS-CoV-2 in long-distance cross-border transportation. In each aspect of stakeholders including governmental supervision, manufacturers and consumers, China should strengthen the risk management of imported cold-chain food to ensure the safety, especially pay attention to the health protection of industry workers in close contact with cold -chain food.

ABSTRACT

Natural product bufotenine (5) which could be isolated from Venenum Bufonis, has been widely used as a tool in central nervous system (CNS) studies. We present here its quaternary ammonium salt (6) which was synthesized with high yields using 5-benzyloxyindole as raw materials, and we firstly discover its analgesic effects in vivo. The analgesic evaluation showed that compounds 5 and 6 had stronger effects on the behavior of formalin induced pain in mice. Moreover, the combination of compound 6 and morphine has a synergistic effect. We intended to explain the molecular mechanism of this effect. Therefore, 36 analgesic-related targets (including 15 G protein-coupled receptors, 6 enzymes, 13 ion channels, and 2 others) were systemically evaluated using reverse docking. The results indicate that bufotenine and its derivatives are closely related to acetyl cholinesterase (AChE) or α

ABSTRACT

Femorotibial mechanical axis (FTMA) is one of important factors influencing clinical effect after total knee arthroplasty (TKA). It is generally believed that the range of lower limb alignment after TKA is controlled within neutral FTMA ± 3 °, which has more advantages in improving joint function, prolonging prosthesis survival rate and reducing revision rate, and obtain better clinical results. Therefore, neutral FTMA is also considered to be the gold standard for TKA. However, with the application of computer-assisted surgery and other technologies, the alignment of FTMA is more accurate than before, but the clinical effect after surgery has not significantly improved. Some scholars have begun to question the necessity of neutral alignment of FTMA, and proposed alignment methods such as kinematics and retained residual deformity, which could achieve better clinical effects. In recent years, it has been reported that FTMA might not be the most important factor influencing postoperative clinical effects, and it is suggested that the arrangement and measurement of lower limbs and the effects on adjacent joint functions could affect clinical effect after TKA. The paper reviews neutral FTMA alignment is still an important factor for success of TKA. After a thorough evaluation according to the patient's condition, it should be appropriately applied in the case of neutral FTMA alignment; the operator should explore other factors which affect clinical outcome after TKA, and improve it to achieve the best therapeutic effect.

Objective:To explore the effect of estrogen-related receptor α (ERRα) on lipopolysaccharide (LPS)-induced vascular endothelial cell apoptosis and tight junction protein degradation.Methods:RPMVECs transfected with shERRα were cultured in vitro and divided into four groups: Normal control group (Ctr group); shERRα knockdown group (shERRα group); normal cells + LPS treated group (LPS group): The cells in the six-well plates were cultured in serum-free medium for 12 h, and then treated with 20 μg/mL LPS for 12 h; and shERRα+LPS group: ERRα knockdown cells were treated as the LPS group. ROS fluorescence kit was used to detect the intracellular ROS levels . Apoptosis ratio was detected by TUNEL staining, AnnexinV-FITC and PI. Cell membrane ZO-1 expression was detected by cellular immunofluorescence, and the levels of apoptosis-related proteins Bcl-2, Bax, Smac, Cytochrome c, and tight junction protein ZO-1, as well as the expression of Occludin, JAM-A and E-Ca at molecular level were detected by Western blot.Results:Compared with the Ctr group and the shERRα group, the ROS level, apoptosis rate (TUNEL test: 16.44 ± 2.55; and flow cytometry test: 23.56 ± 2.22), the expression of pro-apoptotic proteins Bax, Smac and Cytochrome c were increased in the LPS group, while the expression of anti-apoptotic proteins Bcl-2 and tight junction protein were decreased. In the LPS group. Cellular immunofluorescence results showed that the ZO-1 was degraded in the cell membrane and the network structure was broken. Compared with the LPS group, inhibition of ERRα in the shERRα+LPS group increased cell damage.Conclusions:ERRα can negatively regulate the apoptosis and affect the function of pulmonary microvascular endothelial cells, thereby regulating sepsis-induced acute lung injury.

ABSTRACT

OBJECTIVE@#To screen the key Chinese Herbal Medicines (KCHMs) against breast cancer by data mining, and analyze the potential mechanism of KCHMs using network pharmacology method.@*METHODS@#Clinical prescriptions consisted of CHMs for treating breast cancer were screened, and then Traditional Chinese Medicine Inheritance Support System (TCMISS) was applied to obtain the KCHMs. Subsequently, active ingredients and corresponding target genes of KCHMs were searched by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) database, and target genes of breast cancer were collected using OMIM and MalaCards. After that, the overlapping target genes of KCHMs and breast cancer were screened, and the protein-protein interaction (PPI) network was built. In addition, a network of "KCHMs-active ingredients-breast cancer-targets" was constructed by Cytoscape 3.7.1. Finally, Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO) analysis were performed with Database for Annotation, Visualization and Integrated Discovery (DAVID) database to reveal the action mechanism of KCHMs.@*RESULTS@#A total of 7 KCHMs were identified, whose active ingredients include quercetin, luteolin, nobiletin, kaempferol, isorhamnetin, naringenin, and be-ta-sitosterol, etc. Based on protein-protein interaction analysis, core targets were ESR1, MYC, CCND1, EGFR, CASP3, ERBB2, etc. Several KEGG pathways (e.g, PI3K-Akt, p53, ErbB, and HIF-1 signaling pathways) were found.@*CONCLUSION@#Based on the combination of the data mining method and network pharmacology approach, the therapeutic effect of KCHMs on breast cancer may be realized by acting on target genes and signaling pathways related to the formation and progression of breast cancer.

ABSTRACT

BACKGROUND@#To regenerate tissue-engineered cartilage as a source of material for the restoration of cartilage defects, we used a human fetal cartilage progenitor cell pellet to improve chondrogenesis and modulation of the immune response in an In Vivo bioreactor (IVB) system. @*METHODS@#IVB was buried subcutaneously in the host and then implanted into a cartilage defect. The IVB was composed of a silicone tube and a cellulose nano pore-sized membrane. First, fetal cartilage progenitor cell pellets were cultured in vitro for 3 days, then cultured in vitro, subcutaneously, and in an IVB for 3 weeks. First, the components and liquidity of IVB fluid were evaluated, then the chondrogenesis and immunogenicity of the pellets were evaluated using gross observation, cell viability assays, histology, biochemical analysis, RT-PCR, and Western blots. Finally, cartilage repair and synovial inflammation were evaluated histologically. @*RESULTS@#The fluid color and transparency of the IVB were similar to synovial fluid (SF) and the components were closer to SF than serum. The IVB system not only promoted the synthesis of cartilage matrix and maintained the cartilage phenotype, it also delayed calcification compared to the subcutaneously implanted pellets. @*CONCLUSION@#The IVB adopted to study cell differentiation was effective in preventing host immune rejection.

ABSTRACT

Objective::To explore the clinical efficacy of modified Bushen Huoxuetang on kidney deficiency and blood stasis type early unexplained recurrent abortion and its effect on intestinal flora. Method::Totally 90 patients with kidney deficiency and blood stasis type early unexplained recurrent abortion were selected from March 2017 to October 2018.According to the random number table, they were divided into control group and observation group, with 45 cases in each group. The control group was given Bushen Huoxue capsule, while the observation group was given modified Bushen Huoxuetang. After treatment, the clinical efficacy, traditional Chinese medicine (TCM) syndrome scores and adverse reactions of two groups were compared, and the changes of serum inflammatory factors, coagulation function and intestinal flora were detected before and after treatment. Result::After treatment, the total effective rate of the observation group was 91.11%, which was higher than 77.78%of the control group (P<0.05). The scores of TCM syndromes in observation group were significantly lower than that in control group (P<0.05). The levels of C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and interleukin-8 (IL-8) in the observation group were significantly lower than those in control group (P<0.05). The thromboplastin time (APTT), thrombin time (TT) and prothrombin time (PT) in observation group were significantly higher than those in control group, while fibrinogen (FIB) was significantly lower than that in control group (P<0.05). The numbers of enterococcus, yeast and Enterobacter in observation group were significantly lower than those of control group, while the numbers of bifidobacteria and Lactobacillus in observation group were significantly higher than those of control group (P<0.05). The incidence of adverse reactions in observation group was 11.11%, which was lower than 28.89%of the control group (P<0.05). Conclusion::Modified Bushen Huoxuetang has a good clinical efficacy in treating kidney deficiency and blood stasis type early unexplained recurrent abortion, and can reduce the TCM syndrome score. Its mechanism may be related to the reduction of inflammation, and improvement of coagulation function and intestinal flora, with a good safety.
