ABSTRACT

This scoping review aimed to summarize the application information and clinical studies of oral Chinese patent medicines. The oral Chinese patent medicines in treating lung cancer were screened out by searching pf the drug directory, related guidelines, and medical information websites. The data including functions, application, ingredients, and prices of these medicines were collected. Six public databases were searched with the time interval of establishment to August 22, 2021 for collection of the clinical studies of oral Chinese patent medicines in the treatment of lung cancer. The expert consensuses, systematic reviews, randomized controlled trials, non-randomized controlled trials, and non-controlled trials were selected for analysis. A total of 104 oral Chinese patent medicines were screened out, including 31 capsules, 16 granules, 20 oral liquids, 17 tablets, 17 pills, and 3 ointments, in which altogether 198 herbal medicines were involved. The single-dose prices of 2, 36, and 66 medicines were > CNY 100, CNY 10-100, and < CNY 10, respectively. There were 410 clinical studies associated with 48 oral Chinese patent medicines, which were published from 1986 to 2021. These publications included 1 expert consensus, 21 systematic reviews, 277 randomized controlled trials, 87 non-randomized controlled trials, and 24 non-controlled trials. In the clinical studies, the Chinese patent medicines were usually applied in combination with radiotherapy and chemotherapy. The evaluation of primary outcomes focused on 9 indicators including clinical efficacy, quality of life, and incidence of side effects. In conclusion, the oral Chinese patent medicines demonstrated significant advantages in the treatment of lung cancer, and the relevant clinical trials were increasing year by year, with multiple outcome indicators being evaluated. More comprehensive and standardized clinical studies need to be designed for oral Chinese patent medicines in treating lung cancer in the future.

ABSTRACT

ObjectiveTo observe the effect of Xianlian Jiedu prescription (XLJDP) on the proliferation, apoptosis, and migration of cancer-relative endothelial (CRE) cells, and to decipher the mechanism of XLJDP in regulating angiopoietin2 (Ang2) to maintain CRE cell homeostasis and inhibit tumor neovascularization. MethodHuman umbilical vein endothelial cell line (HUVEC-c) was induced into CRE cells in the human colorectal cancer HCT-116 cell-conditioned medium. The CRE cells were assigned into the blank group, conditioned medium group, and XLJDP groups (1, 2, 3 g·L-1) and treated for 48 h. The proliferation of CRE cells was detected by methyl thiazolyl tetrazolium (MTT) colorimetry. The morphological changes of CRE cells were observed via an inverted microscope. The apoptosis rate was detected by flow cytometry. Wound healing test and Transwell migration assay were employed to detect the 2D/3D migration ability of CRE cells. The protein levels of vimentin, N-cadherin, matrix metalloproteinase-9 (MMP-9), and Ang2 in CRE cells were measured by Western blot. ResultThe MTT results showed that the cell viability was higher in the conditioned medium group than in the blank group (P<0.05). Compared with the conditioned medium group, XLJDP decreased the cell proliferation rate (P<0.01) and changed the cell morphology. The total apoptosis rates of all the XLJDP groups were higher than that of the conditioned medium group (P<0.01). The 2D and 3D migration abilities of the conditioned medium group were higher than those of the blank group (P<0.05, P<0.01). Compared with the conditioned medium group, XLJDP at all the concentrations weakened the 2D migration ability (P<0.01) and medium- and high-concentration XLJDP weakened the 3D migration ability (P<0.01). The protein levels of N-cadherin, Vimentin, MMP-9, and Ang2 were up-regulated in the conditioned medium group compared with those in the blank group (P<0.05, P<0.01). Compared with the conditioned medium group, XLJDP at all the concentrations down-regulated the protein level of Ang2 (P<0.05, P<0.01), and medium- and high-concentration XLJDP down-regulated those of N-cadherin, vimentin, and MMP-9 protein (P<0.01). ConclusionXLJDP may inhibit the proliferation, migration, differentiation, and apoptosis of CRE cells by down-regulating the expression of Ang2, inhibiting tumor neovascularization, and maintaining the cell homeostasis.

ABSTRACT

OBJECTIVE@#To compare the operation complexity and accuracy of traditional splint impression technique and impression technique with prefabricated rigid connecting bar system for full-arch implants-supported fixed protheses in vitro.@*METHODS@#Standard mandibular edentulous model with six implant analogs was prepared. The implants were placed at the bone level and multiunit abutments screwed into the implants. Two impression techniques were performed: the traditional splint impression technique was used in the control group, and the rigid connecting bar system was used in the test group. In the control group, impression copings were screwed into the multiunit abutments and connected with autopolymerizing acrylic resin. Open tray impression was fabricated with custom tray and polyether. In the test group, cylinders were screwed into the multiunit abutments. Prefabricated rigid bars with suitable length were selected and connected to the cylinders with small amount of autopolymerizing acrylic resin, and open tray impression was obtained. Impression procedures were repeated 6 times in each group. The working time of the two impression methods were recorded and compared. Analogs were screws into the impressions and gypsum casts were poured. The gypsum casts and the standard model were transferred to stereolithography (STL) files with model scanner. Comparative analysis of the STL files of the gypsum casts and the standard model was carried out and the root mean square (RMS) error value of the gypsum casts of the control and test groups compared with the standard model was recorded. The trueness of the two impression techniques was compared.@*RESULTS@#The work time in the test group was significantly lower than that in the control group and the difference was statistically significant [(984.5±63.3) s vs. (1 478.3±156.2) s, P < 0.05]. Compared with the standard model, the RMS error value of the implant abutments in the test group was (16.9±5.5) μm. The RMS value in the control group was (20.2±8.0) μm. The difference between the two groups was not significant (P>0.05).@*CONCLUSION@#The prefabricated rigid connecting bar can save the chair-side work time in implants immediate loading of edentulous jaw and simplify the impression process. The impression accuracy is not significantly different from the traditional impression technology. The impression technique with prefabricated rigid connecting bar system is worthy of clinical application.

ABSTRACT

Total mesorectal excision (TME) represents the gold standard for radical resection in rectal cancer. The development in radiology and laparoscopic surgical equipment and the advancement in technology have led to a deepened understanding of the mesorectum and its surrounding structures. Both the accuracy of preoperative staging and the preciseness of the planes of TME surgical dissection have been enhanced. The postoperative local recurrence rate is reduced and the long-term survival of rectal cancer patients is improved. The preservation of the pelvic autonomic nervous system maintains the patient's urinary and sexual functions to the greatest extent possible, which in turn improves the patient's postoperative quality of life. A thorough understanding of the anatomy of the mesorectum and its surrounding structures is a prerequisite for successful TME. Herein, we review the basic concepts and the anatomy of the mesorectum in the current literature. Some important clinical issues are also discussed systematically in terms of imaging, surgery, and pathology.

ABSTRACT

Objective: To analyze the clinical characteristics and treatment of critically ill children with acute chlorine poisoning and explore the risk factors and effective strategies. Methods: This retrospective study collected the clinical data, including general state, clinical characteristics, treatment and follow-up(till 1 year and 6 months after discharge), of 6 critically ill children who were hospitalized in the Pediatric Intensive Care Unit of Beijing Children's Hospital due to acute chlorine poisoning in August 2019. Results: There were 6 children characterized by severe dyspnea in this accident, among whom 4 were boys and two girls, aged 4-12 years. When the accident occurred, they were within 5 m of the chlorine source. These patients underwent tracheal intubation and mechanical ventilation in 3.5-7.0 h after poisoning. The child who was the closest to the chlorine source (1.5 m) and took the longest time (5 min) to evacuate was the most severe one. He suffered hypoxia which could not be corrected by conventional mechanical ventilation and severe shock, then had veno-arterial extracorporeal membrane oxygenation(ECMO) treatment started 10 h after the accident. All the 6 children in this study survived. Following-up found no growth and developmental abnormality. The pulmonary function tests were normal except for one case with increased small airway resistance due to previous suspected asthma, and the lung CT, electhoencephalogram, and brain magnetic resonance imaging were all normal. Conclusions: Severe chlorine poisoning is mainly characterized by respiratory failure. Mechanical ventilation is often required within a few hours after poisoning. When conventional mechanical ventilation is ineffective, ECMO could save live. Timely treatment could improve prognosis.

ABSTRACT

Objective:To investigate the therapeutic effect of dabrafenib in treatment of cutaneous melanoma (CMM) and its influence on the expression of pituitary homeobox 1 (PITX1) protein.Methods:A total of 86 patients with CMM admitted to Wuhan First Hospital from November 2016 to December 2017 were selected as the research objects, and all patients were divided into the observation group and the control group according to random number table, 43 cases in each group. The control group received chemotherapy regimen, and the observation group was added with dabrafenib on the basis of the control group. Immunohistochemistry method was used to detect the expressions of PITX1 protein in both groups. The treatment effect, recurrence rate, survival, PITX1 expression positive rate and adverse reactions were compared between the two groups.Results:The treatment effective rate in the observation group was higher than that in the control group [46.51% (20/43) vs. 25.58% (11/43)], and the difference was statistically significant ( χ2 = 3.23, P = 0.043); the disease control rate in the observation group was higher than that in the control group [93.02% (40/43) vs.72.09% (31/43)], and the difference was statistically significant ( χ2 = 5.17, P = 0.023). Compared with the control group, the observation group had better overall survival and progression-free survival, lower recurrence rate, and higher PITX1 positive rate (all P < 0.05); adverse reaction rate in the observation group was lower than that in the control group [11.63% (5/43) vs. 32.56% (14/43)], and the difference was statistically significant ( χ2 = 5.47, P < 0.05). Conclusions:Dabrafenib has a better effect in the treatment of CMM, which can increase the expression level of PITX1, reduce the recurrence rate and the incidence of adverse reactions, and prolong the survival time of patients.

ABSTRACT

Objective:To investigate the effect of interleukin (IL)-7 receptor α (IL-7Rα) antibody on the immune inflammation and renal injury in MRL/lpr lupus mice.Methods:Fifteen 3-4-week-old female MRL/lpr lupus mice (specific pathogen free) weighing 15-16 g were bred to 14-week-old and randomly divided into three groups: IL-7Rα antibody intervention group, isotype antibody (positive control) group and normal saline (negative control) group. The mice in the threc groups were intraperitoneally injected with IL-7Rα antibody, isotype antibody and normal saline respectively, with 100 μg three times a week for 4 weeks. At the age of 18-week old, the mice were sacrificed. Twenty-four-hour urinary protein was detected by Coomassie brilliant blue method, serum creatinine was detected by peroxidase method, and the expression of autoantibody (anti-double strand DNA antibody) and inflammatory factors such as tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ) and IL-21 was detected by enzyme-linked immunosorbent assay method. Renal pathology was detected by PAS and Sirius red staining, and CD3 and F4/80 in renal tissues were detected by immunohistochemistry method. Regulatory T cells, follicullar helper T cells (Tfh) and follicular regulatory T cells (Tfr) were detected by flow cytometry.Results:The 24-hour urinary protein, serum creatinine, serum anti-double strand DNA antibody and serum IFN-γ and IL-21 in the IL-7Rα antibody intervention group were significantly lower than those in the control groups (all P<0.01). However, there was no significant difference in serum TNF-α among the three groups ( F=0.39, P>0.05). The positive infiltrating cells of CD3 and F4/F80, and the ratio of type Ⅰ/Ⅲ collagen fibers ( F=41.11, P<0.01) of renal tissues in the IL-7Rα antibody intervention group were lower than those in the other two groups. Compared with the control groups, the ratio of regulatory T cells (CD4 +CD25 +Foxp3 +)/effector T cells (CD4 +CD25 +) in blood of IL-7Rα antibody intervention group increased ( F=21.64, P<0.01), while the ratio of Tfr (CD4 +CXCR5 +Foxp3 +)/Tfh (CD4 +CXCR5 +) in peripheral blood and spleen increased ( F=38.95, P<0.01; F=12.90, P<0.01). Conclusion:IL-7Rα antibody can reduce the production of autoantibodies such as anti-double strand DNA antibody and inflammatory factors by increasing the ratio of regulatory T cells and Tfr/Tfh, thus alleviating immune inflammation and renal damage in MRL/lpr lupus mice.

ABSTRACT

Objective:To study the correlation between peripheral blood eosinophils levels and clinical characteristics of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods:A retrospective study was conducted in 79 AECOPD patients admitted to the Department of Respiratory and Critical Care Medicine of Peking University Third Hospital from January 2015 to December 2016. Peripheral blood EOS level 100/μl, 300/μl, 2%, 3%, and sputum EOS level 3% were the cut-off values. Patients were divided into EOS≥100/μl group ( n=33), EOS<100/μl group ( n=46); EOS≥300/μl group ( n=10), EOS<300/μl group ( n=69); EOS%≥2% group ( n=27), EOS<2% group ( n=52); blood EOS≥3% group ( n=16), blood EOS<3% group ( n=63); sputum EOS≥3% group ( n=7), sputum EOS<3% group ( n=15) respectively. The study analyzed the differences of clinical features between each two groups of patients; According to the blood EOS level in the acute phase and the recovery phase, ≥100/μl was high and<100/μl was low, they were divided into high EOS in both acute and recovery phase group ( n=21), high EOS in the acute phase and low EOS in the recovery phase group ( n=4), low EOS in the acute phase and high EOS in the recovery phase group ( n=20) and low EOS in both acute and recovery phase group ( n=12). The differences of clinical characteristics in each group were analyzed. Results:The median duration of COPD, proportion of patients with forced expiratory volume in the first second (FEV 1) percentage of predicted value (FEV 1% predicted value)<50%, proportion of complicated with respiratory failure, median level of procalcitonin, proportion of systemic glucocorticoid therapy and median length of stay in the EOS≥100/μl group were all significantly lower than EOS<100/μl group (5 vs 13 years, 48.0% vs 81.8%, 21.9% vs 50.0%, 0.04 vs 0.09 μg/L, 21.2% vs 56.5%, 11 vs 14 d, all P<0.05). The proportion of re-acute exacerbation in the EOS≥300/μl group was significantly higher than EOS<300/μl group (60.0% vs 23.2%), while the median fibrinogen level and median procalcitonin level were significantly lower than EOS<300/μl group (3.38 vs 3.85 g/L, 0.03 vs 0.07 μg/L, all P<0.05). The median duration of COPD, proportion of FEV 1% predicted value<50%, proportion of complicated with respiratory failure, the modified British Medical Research Council′s dyspnea scale (mMRC) score, median fibrinogen level, median C-reactive protein level, median procalcitonin level, proportion of systemic glucocorticoid therapy, proportion of non-invasive ventilation during hospitalization and median length of stay in the EOS≥2% group were all significantly lower than EOS<2% group [5 vs 13 years, 40.9% vs 83.3%, 12.0% vs 51.0%, 3 (2, 3) vs 3 (3, 4) points, 3.37 vs 3.97 g/L, 3.6 vs 16.8 mg/L, 0.04 vs 0.09 μg/L, 14.8% vs 55.8%, 0 vs 19.2%, 9 vs 14 d] (all P<0.05). The median duration of COPD, proportion of complicated with respiratory failure, median level of C-reactive protein and proportion of systemic glucocorticoid therapy in the blood EOS≥3% group were significantly lower than blood EOS<3% group (5 vs 10 years, 6.7% vs 45.8%, 4.4 vs 12.9 mg/L, 12.5% vs 49.2%) (all P<0.05). The median duration of COPD and median length of stay in the sputum EOS≥3% group were significantly shorter than sputum EOS<3% group (2 vs 15 years, 10 vs 21 d), while the median blood EOS count and median blood EOS ratio were significantly higher than sputum EOS<3% group (0.20 vs 0.01×10 9/L, 2.4% vs 0.1%) (all P<0.05). The proportion of complicated with respiratory failure and received systemic glucocorticoid therapy in the high EOS in both acute and recovery phase group were significantly lower than the low EOS in the acute phase and high EOS in the recovery phase group (14.3% vs 75.0%, 14.3% vs 55.0%) (all P<0.05). The proportion of FEV 1% predicted value <50% in the high EOS in the acute phase and low EOS in the recovery phase group was significantly lower than the low EOS in the acute phase and high EOS in the recovery phase group (0 vs 82.4%) ( P<0.05). The median FEV1% predicted value level in the high EOS in the acute phase and low EOS in the recovery phase group was significantly higher than the low EOS in both acute and recovery phase group (59.5% vs 36.0%) ( P<0.05). Conclusions:High EOS AECOPD patients have a shorter duration of disease and fewer days of hospitalization. The proportion of patients complicated with respiratory failure is lower. It is easier to distinguish the differences in clinical characteristics of AECOPD patients with a blood EOS count of 100/μl as a cut-off value. EOS levels in the acute phase and the recovery phase are helpful to distinguish the clinical characteristics of AECOPD patients.

ABSTRACT

Objective:To analyze the influencing factors of short-term efficacy of 125I seed implantation for recurrent cervical metastatic lymph nodes of esophageal squamous cell carcinoma after external beam radiation therapy (RESCC). Methods:From January 2013 to March 2019, 47 patients (42 males, 5 females; age: 47-77 years) with RESCC who underwent CT guided 125I seed implantation in Hebei General Hospital were retrospectively analyzed. Patients were divided into effective group (complete remission (CR)+ partial remission (PR)) and ineffective group (stable disease (SD)+ progressive disease (PD)) according to response evaluation criteria in solid tumors (RECIST) at 3 months after implantation. Multivariate logistic regression was used to analyze the independent influencing factors of short-term efficacy. Cut-off values were determined by ROC curve. Results:Of 47 patients, 26 were effective (3 were CR and 23 were PR) and 21 were ineffective (7 were SD, 14 were PD). Multivariate regression analysis showed that tumor diameter, immediate postoperative dose delivered to 90% gross tumor volume ( D90), recurrence interval time were independent influencing factors of short-term efficacy (odds ratio ( OR; 95% CI): 4.240(1.220-14.737), 0.999(0.999-1.000), 0.989(0.979-1.000), Wald values: 5.163, 5.043, 3.956, all P<0.05). ROC curve showed that the AUC of tumor diameter, D90 and recurrence interval time were 0.782, 0.786 and 0.838 respectively, with cut-off values of 4.85 cm, 115.78 Gy and 297.5 d respectively. Conclusions:The short-term efficacy of 125I seed implantation for RESCC is mainly related to the tumor diameter, immediate postoperative D90 and recurrence interval time. Patients with tumor diameter <4.85 cm, immediate postoperative D90>115.78 Gy and recurrence interval time >297.5 d have better efficacy.

ABSTRACT

Objective:To investigate the efficacy of the Mini-Mental State Scale (MMSE) versus the Montreal Cognitive Assessment Scale (MoCA) in screening cognitive impairment in patients with a lacunar cerebral infarction. Methods:138 eligible patients who received treatment in the Affiliated Hospital of Shanxi Datong University from January 2018 to October 2019 were recruited for this study. They received cognitive function evaluation by the MMSE and MoCA. These patients were grouped according to the median number of age or the median number of years of education. The sensitivity and consistency of the MMSE versus MoCA in screening cognitive impairment in patients with a lacunar cerebral infarction were analyzed using the χ2 test. The total cognitive scores of the MMSE and MoCA, and the scores of each cognitive domain such as memory, execution, visual space, attention, language, and orientation, were compared between groups using multiple linear regression analysis. Results:The sensitivity of MoCA in screening for cognitive impairment in low-age, high-age, low-year-education, and high-year-education groups and the whole population of patients with a lacunar cerebral infarction was 76.5%, 75.7%, 74.2%, 77.8%, 76.1%, respectively, which were significantly higher than those of MMSE (44.1%, 65.7%, 60.6%, 50.0%, 55.1%, χ2 = 12.17, 13.13, 9.33, 15.75, 23.86, all P < 0.01). The Kappa coefficients of low-age, high-age, low-year-education and high-year-education groups were 0.336, 0.391, 0.358, 0.389, and 0.373, respectively, all of which were less than 0.4 (all P < 0.01). These findings suggest that the consistency of the two scales in screening cognitive impairment is poor. The cognitive impairment detection rate by the MMSE was significantly higher in the high-age group than in the low-age group (65.7% vs. 44.1%, χ2 = 6.50, P < 0.05). The total cognitive scores of MMSE and MoCA and the scores of memory, execution, visual space, attention, language, and orientation in patients with a lacunar cerebral infarction were significantly lower in the high-age group or low-year-education group than in the low-age group ( tMMSE = 3.61, 2.49, 3.12, 4.26, 1.70, 3.69, 2.24, all P < 0.01; tMoCA = 3.83, 1.75, 3.28, 3.80, 2.21, 4.08, 2.52, all P < 0.05) or high-year-education group ( tMMSE = -2.87, -2.32, -0.85, -2.54, -0.73, -2.57, -2.96, all P < 0.01; tMoCA = -2.95, -1.12, -3.39, -1.54, -1.52, -3.09, -3.02, all P < 0.05). Conclusion:Combined application of MMSE and MoCA has a high clinical value in screening cognitive impairment in patients with a lacunar cerebral infarction. High-age patients with a lacunar cerebral infarction who receive low-year education have memory, execution, visual space, attention, language, and orientation impairments.

ABSTRACT

Objective:To understand the sales characteristics and salt iodine content in urban and rural salt market of Guizhou Province.Methods:In accordance with the "Guizhou Province 2020 Iodine Deficiency Disorders Monitoring Field Technical Guidance Work Program", 14 counties (cities, districts) from 88 counties (cities, districts) of 9 cities (states) in Guizhou Province were selected in August 2020. Each county (city, district) selected the urban area and a representative township, and at least 2 supermarkets were selected from the urban area, and 5 supermarkets or retail stores from the townships as the investigation sites, to collect the label information of all commercially available salt within the scope of investigation. At the same time, salt samples were collected after excluding the same brand, variety, and specification, and salt iodine was detected by redox titration.Results:A total of 107 labels of commercially available salt were collected, involving 21 brands, of which Biyuan brand had the largest number (53 samples, 49.5%) and the widest sales range, involving 12 counties (cities, districts). Salt producing areas came from 13 provinces, and the salt produced in Sichuan Province was the most widely distributed in the surveyed area (36 samples), followed by Chongqing Municipality (17 samples) and Hubei Province (16 samples). There were 19 brands (75 samples) and 7 brands (32 samples) of salt sold in urban and rural areas, respectively, and the main brand was Biyuan, accounting for 38.7% (29/75) and 75.0% (24/32), respectively. There were 8 brands (27 samples) and 16 brands (80 samples) of salt sold in retail stores and supermarkets, respectively, and the main brand was Biyuan, accounting for 66.7% (18/27) and 43.8% (35/80), respectively. Among 107 salt samples, it was found that the labeled iodine content did not meet the Guizhou Province salt iodization implementation standard (21 - 39 mg/kg), and only 39 samples (36.4%) had electronic anti-counterfeiting traceability codes on their labels. After excluding the same brand, variety, and specification, the median salt iodine of the 51 salt samples was 23.6 mg/kg, ranging from 19.2 to 38.1 mg/kg, and 21 - 39 mg/kg accounted for 96.1% (49/51).Conclusions:There are many salt brands sold in urban and rural areas in Guizhou Province, and the electronic traceability platform needs to be improved. Salt iodine is mainly distributed in the low-value area of the standard range, which brings potential risks to the sustainable and effective prevention and control of iodine deficiency disorders.

ABSTRACT

We reviewed and developed an indicator system framework for assessing teaching effect of laparoscopic simulation training through literature research, expert consultation, analytic hierarchy process and factor analysis. We also made an empirical study on the constructed index system. The system included 3 domains (A1: evaluation of laparoscopic simulator; A2: operation evaluation of experimental animals; A3: evaluation of clinical practice), 10 second-level indicators and 23 third-level indicators for assessing teaching effect of laparoscopic simulation training. The indicator system framework has good internal consistency (Cronbach α= 0.968) and external consistency (>0.72). The empirical study found that: in the results of A1-A3 in the first level indicator, the score of the experienced group was significantly higher than that of the inexperienced group ( P<0.05). In the evaluation results of the 10 secondary indicators in the secondary indicators B1-B10, the score of the experienced group was significantly higher than that of the inexperienced group ( P<0.01). For the first time, we have established and evaluated a comprehensive evaluation indicator system which is reliable and effective and can be used for further evaluation of teaching effect of laparoscopic simulation training. The following empirical studies have verified the effectiveness and practicability of the evaluation system.

ABSTRACT

Objective:To investigate the relationship between dosimetric parameters and tumor volume change after 125I implantation for thyroid cancer and obtain better dosimetric parameters that predict the curative effect more accurately. Methods:A total of 22 consecutive patients with thyroid cancer (23 targets) who received 125I interstitial brachytherapy in Department of Oncology, Hebei General Hospital were retrospectively analyzed. All the patients received post-operative dose verification, and the D 90 (Minimum dose received by 90% target volume) was calculated. After a regular follow-up, the tumor volume reduction ratio after t months (R t) , actual absorbed dose (D 1m) , efficacy corrected absorbed dose (D 1e) , and sensitivity corrected absorbed dose (D 1s) of the first month were calculated according to the actual follow-up CT images. The statistical test was carried out by SPSS21.0. The Spearman linear analysis was applied to analyze the relationship between D 90, D 1m, D 1e, D 1s and R t, and the curve fitting was also completed.

ABSTRACT

@#Objective    To summarize our experience in the treatment of esophageal foreign bodies. Methods    A retrospective analysis of 149 patients of esophageal foreign bodies in the Second Affiliated Hospital of Air Force Military Medical University from December 2011 to May 2019 was carried out, including 75 (50.3%) females and 74 (49.7%) males with an average age of 57 (2-85) years. Results    There were 146 patients confirmed by endoscopy, and 3 patients were not found foreign body. Among the confirmed patients, 127 patients were removed by gastroscope and 19 patients were treated by operation. Esophageal foreign bodies are mainly related to the types of food. Jujube seed is the most common food foreign body in the northwest China. The injury rate of mucosal was 47.54% within 48 hours. The complication rate of taking out the foreign body after 48 hours was 100.0%. The success rate by endoscopy decreased (P=0.005), if the foreign body combined perforation. There was no statistical difference between the neck and other parts when using ultra-fine gastroscope (P=0.157). Conclusion    The sharper the foreign body is, the easier the perforation is. The earlier the foreign body is removed, the less complications are. The size of the foreign body determines the difficulty of endoscopic removal. Gastroscopy is the first choice for diagnosis and treatment, especially ultra-fine gastroscopy, and the foreign bodies that cannot be removed by endoscopy need surgical treatment.

ABSTRACT

OBJECTIVE To study the mechanism of curcumol inhibiting the pro liferation of breast cancer cells T 47D. METHODS MTT assay was used to detect the inhibitory effects of different doses of curcumol (0,6.25,12.5,25,50,100 μg/mL)on the proliferation of T 47D cells. After treated with curcumol (12.5,25,50,100 μg/mL),the morphology of T 47D cells was observed by inverted phase contrast microscope. The cell cycle and the levels of reactive oxygen species (ROS)were detected by flow cytometry. Quantitative real-time PCR (qRT-PCR)was used to detect the expressions of proliferating cell nuclear antigen (PCNA),cell cycle regular p 21 and cyclin-dependent kinase 2(CDK2)mRNA. Western blot assay was used to detect the protein expression of CDK 2,CDK6,Cyclin D ,PCNA,nucler transcription factor E 2-related factor (Nrf2)and Kelch-like ECH associated protein 1(Keap1). Breast cancer cells T 47D were divided into 2 groups,one group was given different doses of curcumol ,and another group was given curcumol 33 μg/mL for 6,12,24,48 h. After the optimal oxidation time and administration concentration were determined according to the results of the above two groups ,the blank control group ,N-acetylcysteine(NAC)group(ROS antioxidant NAC alone ),curcumol group (curcumol alone ),curcumol combined with NAC group (pretreatment with ROS antioxidant NAC ,and then adding into curcumol ). Cell cycle and fluorescence intensity of ROS were detected. RESULTS Curcumol could significantly increase the inhibitory rate of the proliferation of T 47D cells (P<0.05 or P<0.01),and showed a certain dose and time dependent trend. Curcumol blocked the , cycle in the G 1 phase and significantly increased the level of ROS (P<0.05 or P<0.01);ROS antioxidant NAC could significantly reverse above inductive effect of curcumol (P< 0.01). qRT-PCR showed that curcumol down-regulated the com expression of PCNA and CDK 2 mRNA and up-regulated the expression of p 21 mRNA(P<0.05 or P<0.01). Western blot assay showed that curcumol significantly down-regulated the edu.cn protein expression of Keap 1,Nrf2,CDK2,CDK6 and Cyclin D(P<0.05,P<0.01);ROS antioxidant NAC could reverse the down-regulation effects of curcumol on the expression of these proteins(P<0.05 or P<0.01). CONCLUSIONS Curcumol may induce oxidative stress and cell arrest in G 1 phase to inhibit the proliferation of T 47D cells.

ABSTRACT

OBJECTIVE@#To evaluate the value of high mobility group protein B1 (HMGB1) and soluble receptor for advanced glycation end products (sRAGE) in the diagnosis, efficacy monitoring and prognosis of newly diagnosed multiple myeloma (MM) patients.@*METHODS@#Fifty newly diagnosed MM patients before and after chemotherapy and 50 hematological outpatients from October 2018 to May 2020 were selected. Enzyme linked immunosorbent assay (ELISA) was used to detect the serum HMGB1 and sRAGE levels of the patients. ROC was used to further analyze the efficacy of serum HMGB1 and sRAGE levels on the diagnosis of MM. At the same time, the serum levels of HMGB1 and sRAGE before and after chemotherapy were compared, and their values in the evaluation of curative effect of MM patients were analyzed. According to the mean values of serum HMGB1 and sRAGE, all the patients were divided into different groups, the clinical characteristics and survival status of the patients were compared.@*RESULTS@#Before treatment the serum HMGB1 level of the patients in MM group was higher than that in control group, while sRAGE level was lower (t=11.363,6.127, P<0.001). The AUC of serum HMGB1 and sRAGE in the MM patients was 0.955 and 0.811, respectively. After 3 courses of chemotherapy, HMGB1 level of the patients in CR group was lower than before chemotherapy, while in PD group was higher, as well as sRAGE level of the patients in PR group (P<0.05). There were significant differences in R-ISS stage, HGB, CRP, ESR, CD56, CD117, D13S319 deletion between HMGB1 high expression group and HMGB1 low expression group (χ2=3.920, 6.522, 6.65, 4.16, 3.945, 6.65, 4.16, P<0.05), while there were significant differences in ISS stage, CRP and CD56 between sRAGE low expression group (28 cases) and sRAGE high expression group (22 cases) (χ2=4.565, 4.711, 5.547, P<0.05). Kaplan-Meier survival analysis showed that the patients in HMGB1 low expression group had better survival condition, for PFS Tlow>Thigh (χ2=9.470, P<0.05), and for OS Tlow>Thigh (χ2=7.808, P<0.05); there was no difference in the survival of sRAGE high expression group and low expression group, for PFS Tlow<Thigh (χ2=1.661, P>0.05), and for OS Tlow<Thigh (χ2=2.048, P>0.05). Cox analysis showed that LDH and HMGB1 were the factors affecting the prognosis of the patients, and both of them affected PFS (HR=2.771, 95% CI: 1.002-7.662, P=0.049; HR=6.022, 95% CI: 1.689-21.470, P=0.006), while HMGB1 also affected OS (HR=4.275, 95% CI: 1.183-15.451, P=0.027).@*CONCLUSION@#The serum HMGB1 and sRAGE have certain auxiliary value for the diagnosis and curative effect monitoring of newly diagnosed MM patients, and serum HMGB1 is expected to be an auxiliary detection index for the prognosis of MM.

ABSTRACT

OBJECTIVE@#To analyze the characteristics of gene mutation and overexpression in newly diagnosed multiple myeloma (NDMM) patients.@*METHODS@#Bone marrow cells from 208 NDMM patients were collected and analyzed. The gene mutation of 28 genes and overexpression of 6 genes was detected by DNA sequencing. Chromosome structure abnormalities were detected by fluorescence in situ hybridization (FISH).@*RESULTS@#Gene mutations were detected in 61 (29.33%) NDMM patients. Some mutations occurred in 5 or more cases, such as NRAS, PRDM1, FAM46C, MYC, CCND1, LTB, DIS3, KRAS, and CRBN. Overexpression of six genes (CCND1, CCND3, BCL-2, CCND2, FGFR3, and MYC) were detected in 83 (39.9%) patients, and cell cycle regulation gene was the most common. Single nucleotide polymorphisms (SNP) changes were detected in 169 (81.25%) patients, the TP53 P72R gene SNP (70.17%) was the most common. Abnormality in chromosome structure was correlated to gene overexpression. Compared to the patients with normal chromosome structure, patients with 14q32 deletion showed higher proportion of CCND1 overexpression. Similarly, patients with 13q14 deletion showed higher proportion of FGFR3 overexpression, whereas patients with 1q21 amplification showed higher proportion of CCND2, BCL-2 and FGFR3 overexpression.@*CONCLUSION@#There are multiple gene mutations and overexpression in NDMM. However, there is no dominated single mutation or overexpression of genes. The most common gene mutations are those in the RAS/MAPK pathway and the genes of cyclin family CCND are overexpression.

ABSTRACT

OBJECTIVES@#To study the efficacy and safety of early intratracheal administration of budesonide combined with pulmonary surfactant (PS) in preventing bronchopulmonary dysplasia (BPD).@*METHODS@#A prospective randomized controlled trial was designed. A total of 122 infants with a high risk of BPD who were admitted to the neonatal intensive care unit of the Third Affiliated Hospital of Zhengzhou University from January to July 2021 were enrolled. The infants were randomly divided into a conventional treatment group with 62 infants (treated with PS alone at an initial dose of 200 mg/kg, followed by a dose of 100 mg/kg according to the condition of the infant) and an observation group with 60 infants (treated with PS at the same dose as the conventional treatment group, with the addition of budesonide 0.25 mg/kg for intratracheal instillation at each time of PS application). The two groups were compared in terms of the times of PS use, ventilator parameters at different time points, oxygen inhalation, incidence rate and severity of BPD, incidence rate of complications, and tidal breathing pulmonary function at the corrected gestational age of 40 weeks.@*RESULTS@#Compared with the conventional treatment group, the observation group had a significantly lower proportion of infants using PS for two or three times (P<0.05). Compared with the conventional treatment group, the observation group had a significantly lower fraction of inspired oxygen at 24 and 48 hours and 3, 7, and 21 days after administration, significantly shorter durations of invasive ventilation, noninvasive ventilation, ventilator application, and oxygen therapy, a significantly lower incidence rate of BPD, and a significantly lower severity of BPD (P<0.05). There was no significant difference in the incidence rate of glucocorticoid-related complications between the two groups (P>0.05).@*CONCLUSIONS@#Compared with PS use alone in preterm infants with a high risk of BPD, budesonide combined with PS can reduce repeated use of PS, lower ventilator parameters, shorten the duration of respiratory support, and reduce the incidence rate and severity of BPD, without increasing the incidence rate of glucocorticoid-related complications.

ABSTRACT

This study aims to explore the toxicity mechanism of Rhododendri Mollis Flos(RMF) based on serum metabolomics and network toxicology. The toxic effect of RMF on normal rats was evaluated according to the symptoms, serum biochemical indexes, and histopathology. Serum metabolomics was combined with multivariate statistical analysis to search endogenous differential metabolites and related metabolic pathways. The toxic components, targets, and signaling pathways of RMF were screened by network toxicology technique, and the component-target-metabolite-metabolic pathway network was established with the help of serum metabolomics. The result suggested the neurotoxicity, hepatotoxicity, and cardiotoxicity of RMF. A total of 31 differential metabolites and 10 main metabolic pathways were identified by serum metabolomics, and 11 toxic components, 332 related target genes and 141 main signaling pathways were screened out by network toxicology. Further analysis yielded 7 key toxic components: grayanotoxin Ⅲ,grayanotoxinⅠ, rhodojaponin Ⅱ, rhodojaponin Ⅴ, rhodojaponin Ⅵ, rhodojaponin Ⅶ, and kalmanol, which acted on the following 12 key targets: androgen receptor(AR), albumin(ALB), estrogen receptor β(ESR2), sex-hormone binding globulin(SHBG), type 11 hydroxysteroid(17-beta) dehydrogenase(HSD17 B11), estrogen receptor α(ESR1), retinoic X receptor-gamma(RXRG), lactate dehydrogenase type C(LDHC), Aldo-keto reductase(AKR) 1 C family member 3(AKR1 C3), ATP binding cassette subfamily B member 1(ABCB1), UDP-glucuronosyltransferase 2 B7(UGT2 B7), and glutamate-ammonia ligase(GLUL). These targets interfered with the metabolism of gamma-aminobutyric acid, estriol, testosterone, retinoic acid, 2-oxobutyric acid, and affected 4 key metabolic pathways of alanine, aspartate and glutamate metabolism, cysteine and methionine metabolism, steroid hormone biosynthesis, and retinol metabolism. RMF exerts toxic effect on multiple systems through multiple components, targets, and pathways. Through the analysis of key toxic components, target genes, metabolites, and metabolic pathways, this study unveiled the mechanism of potential neurotoxicity, cardiotoxicity, and hepatotoxicity of RMF, which is expected to provide a clue for the basic research on toxic Chinese medicinals.
