ABSTRACT
Objective:To investigate the protective effect of racanisodamine on lung injury in mice exposed to irradiation.Methods:C57BL/6 mice were randomly divided into control group, racanisodamine group, 18 Gy irradiation group (model group) and racanisodamine combined with 18 Gy irradiation group (treatment group), with 5 mice in each group. The mice in the treatment group received racanisodamine (5 mg/kg) intraperitoneally 3 d before irradiation and contained the whole experiments. Then, single chest irradiation of 18 Gy X-rays was performed both in the model and treatment groups. The racanisodamine group and treatment group received racanisodamine intraperitoneally once a day until 6 weeks after irradiation. The mice were killed at 6 weeks after irradiation. The lung histopathology was observed by HE staining. Serum and bronchial alveolar lavage fluid (BALF) inflammatory cytokines such as TNF-α, IL-1β and IL-6 were determined by ELISA method. Cell senescence was detected by SA-β-Gal staining. The expressions of Nrf2, p-Nrf2 and p62 in lung tissue were performed by immunehistochemistry and Western blot assays.Results:Compared with the model group, the scores of HE staining were decreased ( t=8.66, P<0.01), the number of infiltrated inflammatory cells in BALF were decreased ( t=10.70, P<0.01), and protein concentration in BALF had lower levels ( t=6.75, P<0.01), the serum TNF-α, IL-1β and IL-6 were decreased significantly ( t=8.17, 4.58, 6.54, P<0.01), the activity of SA-β-gal was decreased, and the expressions of Nrf2, p-Nrf2 were enhanced ( t=6.42, 7.30, P<0.01), while the expression of p62 was reduced ( t=4.62, P<0.01) in the treatment group. Conclusions:Racanisodamine plays the protective effect of radiation-induced lung injury by alleviating inflammation associating with the activating of Nrf2-related pathway, which reversed radiation-induced cell senescence.
ABSTRACT
ObjectiveTo explore the related factors of troublemaking behaviors among patients with mental disorders induced by amphetamine-type stimulants （ATS）， and to provide references for the formulation of relevant intervention measures for ATS-induced mental disorders. MethodsA total of 105 patients who met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） for ATS-induced mental disorders were included， and classified into troublemaking group and non-troublemaking group. The general demographic data and clinical data of the selected individuals were collected， and all patients were assessed using Social Support Rating Scale （SSRS）. Then univariate analysis and multivariate Logistic regression model were used to screen the related factors of troublemaking behaviors. ResultsThe scores of SSRS， objective support dimension and social support utilization dimension were significantly lower in troublemaking group than those in non-troublemaking group， with statistical differences ［（24.10±6.59） vs. （28.94±5.59）， t=3.364， P=0.001； （5.50±1.96） vs. （8.20±2.13）， t=5.183， P<0.01； （4.60±2.26） vs. （6.28±1.90）， t=3.435， P=0.001］. Multivariate Logistic regression analysis showed that male （OR=6.061， P=0.014） was a risk factor， while high social support level （OR=0.873， P=0.018） was the protective factor for troublemaking behaviors among patients with ATS-induced mental disorders. ConclusionPatients with ATS-induced mental disorders of the males and with low social support level are at high risk of troublemaking behaviors.
ABSTRACT
Colorectal cancer (CRC) is the most lethal gastrointestinal cancer in both males and females worldwide (Sung et al., 2021). Because of the high heterogeneity of tumors, robust prognostic biomarkers are urgently needed in CRC management (Koncina et al., 2020). Chemokine signaling is a well-known pivotal player in immunity, inflammation, and cancer metastasis (Lacalle et al., 2017; Poeta et al., 2019; Do et al., 2020), and multiple genes involved in chemokine signaling have been demonstrated as potential prognostic biomarkers for CRC (Cabrero-De Las Heras and Martínez-Balibrea, 2018; Ottaiano et al., 2020; Yu et al., 2020). Therefore, the aim of our study was to develop a chemokine signaling-based multigene signature (CSbMgSig) that could effectively predict overall survival (OS) and therapeutic response for patients with CRC.
ABSTRACT
Purpose@#Whether craniospinal irradiation (CSI) could be replaced by limited-field radiation in non-metastatic bifocal germinoma remains controversial. We addressed the issue based on the data from our series and the literature. @*Methods@#Data from 49 patients diagnosed with non-metastatic bifocal germinoma at our hospital during the last 10 years were collected. The Pediatric Quality of Life Inventory 4.0 was used to evaluate health-related quality of life (HRQOL). Additionally, 81 patients identified from the literature were also analyzed independently. @*Results@#In our cohort, 34 patients had tumors in the sellar/suprasellar (S/SS) plus pineal gland (PG) regions and 15 in the S/SS plus basal ganglia/thalamus (BG/T) regions. The median follow-up period was 52 months (range, 10 to 134 months). Our survival analysis showed that patients treated with CSI (n=12) or whole-brain radiotherapy (WBRT; n=34) had comparable disease-free survival (DFS; p=0.540), but better DFS than those treated with focal radiotherapy (FR; n=3, p=0.016). All 81 patients from the literature had tumors in the S/SS+PG regions. Relapses were documented in 4/45 patients treated with FR, 2/17 treated with whole-ventricle irradiation, 0/4 treated with WBRT, and 1/15 treated with CSI. Survival analysis did not reveal DFS differences between the types of radiation field (p=0.785). HRQOL analysis (n=44) in our cohort found that, compared with S/SS+PG germinoma, patients with BG/T involvement had significantly lower scores in social and school domains. However, HRQOL difference between patients treated with CSI and those not treated with CSI was not significant. @*Conclusion@#In patients with non-metastatic bifocal germinoma, it is rational that CSI could be replaced by limited-field radiation. HRQOL in patients with BG/T involvement was poorer.
ABSTRACT
Objective:To explore the effect of Dachengqi Decoction on the postoperative recovery of laparoscopic gastrectomy under general anesthesia.Methods:From March 2015 to May 2018, 96 patients with gastric cancer undergoing laparoscopic gastrectomy under general anesthesia in our hospital were selected as the study objects and divided into two groups according to the random number table method. The control group received routine nursing. The observation group received the intervention of Dachengqi Decoction with ultrasonic conductivity on the basis of the control group. The recovery of gastrointestinal function, the levels of gas (serum gastrin), MTL (plasma motilin) and Quality of Recovery 40 (QoR40) were compared between the two groups.Results:The gastrointestinal function indexes of the observation group were better than those of the control group ( P<0.05). Compared with one day before operation, the levels of gas and MTL in the two groups were lower 24 hours after operation, but the levels of GAS and MTL in the observation group were (92.56±5.12), (258.58±5.59) ng/L, which were higher than (52.12±3.15), (185.63±4.12) ng/L in the control group ( t values were 46.608, 72.782, P<0.01). Compared with the pre intervention group, QoR40 scores of the two groups were improved after intervention, and the observation group was (198.56±5.58) points, which was higher than (152.12±2.63) points of the control group ( t value was 52.157, P<0.01). Conclusion:Dachengqi Decoction can promote the recovery of patients after laparoscopic gastrectomy under general anesthesia.
ABSTRACT
Objective@#To explore the relationship between protease-chymase secreted by mast cells, and activated transforming growth factor-β1(TGF-β1), in skin with secondary lymphedema(SLE)in lower extremity, so as toidentify the key factors in fibrosis of lymphedema.@*Methods@#In this study, the affected limb skin of 7 SLE patients was includedas the experimental group, and normal skin tissue of the lower limb of 7 volunteers was used as controls. The skin samples were assayed by Masson staining, and the expressions of chymase and TGF-β1 were assayed by immunohistochemistry, immunofluorescent staining and enzyme-linked immunosorbent assay.@*Results@#There was obvious fibrosis in the skin of lower extremity in patients with lymphedema. The number of MCs andthe expressions of chymase, latency-associated peptide TGF-β1 (LAP TGF-β1) and TGF-β1 were all significantly increased in fibrotic skin in lymphedema, compared with those in normal skin. At the same time, the chymase-containing mast cells accumulated in the lymphatic vessels, with higher expression of TGF-β1.@*Conclusions@#The expression of chymase and TGF-β1 was significantly increased in the fibrotic skin insecondary lower extremity lymphedema. The increased expression of chymase in the skin may activate more TGF-β1 expression, and the increased TGF-β1 may promote skin fibrosis in SLE.

AAT can be performed with auricular acupoints and pain points corresponding to auricular points. The seed is not kept as a pressed bean material, and the adult patient himself is pressed to take the patient′s "getting gas". The duration of AAT is related to the type of pain. Although there is no uniform data on the number of auricular compressions/d and the length of each compression, there is a certain tendency.
ABSTRACT
Objective@#To analyze the clinicopathological features of type 2 diabetes mellitus complicated with colorectal cancer (DCRC).@*Methods@#A case-control study was conducted. Inclusion criteria: (1) hospitalized patients receiving fibrocolonoscopy; (2) adenocarcinoma and mucinous adenocarcinoma diagnosed by pathology; (3) with preoperative cTNM clinical staging; (4) colorectal cancer patients undergoing surgical treatment; (5) with postoperative pTNM staging; (6) no smoking or drinking habits. Exclusion criteria: (1) familial adenomatous polyposis (FAP); (2) Lynch syndrome; (3) carcinoma of anal canal and perianal carcinoma; (4) multiple primary cancer; (5) with serious cardiocerebrovascular diseases or multiple organ failure. Clinicopathlogical data of 32 DCRC patients who were diagnosed and treated in Peking University Shougang Hospital from December 2017 to December 2018 were retrospectively collected and analyzed. Forty nondiabetic colorectal cancer (CRC) patients during the same period were selected as control group according to the sex ratio and the age difference less than 5 years. Student′s t test and χ2 test were used to compare the difference between the two groups in baseline clinicopathological data, clinical test results, tumor markers and infiltration status of T cells in tumor immune microenvironment.@*Results@#Among 32 DCRC patients, 24 were males and 8 were females with a mean age of (63.0±1.7) years; among 40 CRC patients, 30 were males and 10 were females with a mean age of (60.5±1.6) years. The duration of diabetes mellitus in DCRC patients (from the diagnosis of diabetes mellitus to the diagnosis of colorectal cancer) was (9.2±1.3) years. The body mass index (BMI) of DCRC group was significantly higher than that of CRC group [(24.8±0.6) kg/m2 vs. (23.2±0.4) kg/m2, t=2.372, P=0.020]. There were no significant differences in other baseline data (sex, age, primary site of tumor, R0 resection rate, pathological stage, pathological type, differentiation degree of tumor, preoperative intestinal obstruction) between the two groups (all P>0.05). Serum triglyceride level in DCRC group was higher than that in CRC group [(2.1±0.2) mmol/L vs. (1.5±0.1) mmol/L, t=3.085, P=0.003], while hemoglobin [(120.3±5.2) g/L vs. (132.7±2.8) g/L, t=-2.224, P=0.029], anti- thrombin III [(94.2±3.7)% vs. (103.5±2.4)%, t=-2.197, P=0.031], and red blood cell count [(4.2±0.1)×1012/L vs. (4.5±0.1)×1012L, t=-2.055, P=0.044] were all lower than those in CRC group. The preoperative carcinoembryonic antigen (CEA) level in DCRC group was higher than that in CRC group [(50.3±21.8) μg/L vs. (5.6±1.0) μg/L, t=2.339, P=0.022]. There were no significant differences in preoperative levels of other four tumor molecular markers (CA199, CA242, CA724 and CA125) between the two groups (all P>0.05). The expression of Foxp3 [specific markers of CD4+, CD25+ regulatory T cells (Treg)] in DCRC group was higher than that in CRC group [(82.7±6.2) cell/HPF vs. (62.6±4.9) cell/HPF, t=2.586, P=0.012]. There were no significant differences in the infiltration of CD4, CD8, PD-1 and PD-L1 positive cells between two groups (all P>0.05).@*Conclusions@#The average diabetic history of DCRC patients is nearly 10 years. They have higher BMI and serum CEA level, and more Treg cell infiltration in the tumor. Close attention should be paid to these patients in clinical practice.

ABSTRACT
Objective@#To explore the appropriate treatment cycle of complex decongestive Therapy (CDT) for extremity lymphedema, which is the summary of the relationship between treatment time and curative effect.@*Methods@#From January to December 2015, 203 patients with limb lymphedema were divided into four stages according to the degree of edema and the degree of fibrosis, that is, four groups. All patients were given CDT treatment for a course of treatment (4 weeks). During the treatment period, the multi frequency bioelectrical resistance body composition analyzer was used to monitor the change of tissue moisture and the tape diameter was used to measure the circumference of the affected limb. SPSS software is used to analyze the data.@*Results@#203 cases were treated with CDT therapy. Water in limb tissue and limb circumference of affected side was decreased significantly (P<0.01). To the tissues water dynamic changes, in the first group there was a significant difference (P<0.01) in the first week and second week. There was no obvious difference in 2-4 weeks; In the 2, 3 and 4 groups, there was significant difference in the first week and the second week, as well as the second week and the third week (P<0.05). And there was no difference in the third and fourth week. To the circumference dynamic change, in the first group there was no significant difference in patients in the first and the second week; In the third group, there was significant difference in the first week and the second week, as well as the second week and the third week (P<0.05). There was no significant difference in the last two weeks; In the fourth group, there was significant difference in the first week and the second week, as well as the third week and the fourth week(P<0.01). There was no difference in the second week and the third week. There is a correlation between the tissue water and the circumferential diameter (r=0.643). The patient has a good subjective feeling.@*Conclusions@#CDT therapy is effective in the treatment of lymphedema. For the first stage of edema, the therapy lasted two-week at least; For the second and the third stage edema, a 3 week therapy was suitable; For the fourth stage therapy, a four-week therapy is appropriate. It is suggested that CDT therapy should be maintained for at least half a year or so.
ABSTRACT
Objective@#To evaluate the diagnostic value of indocyanine green(ICG)lymphography in primary lymphedema of extremities.@*Methods@#61 patients with limb lymphedema were enrolled in the study. The contralateral healthy limbs were used as controls. After intradermal injection of Indocyanine Green, dynamic observation of lymphatic vessels and lymph flow was performed using PDE near-infrared fluorescent instrument. The frequency of lymphatic contraction was calculated.@*Results@#Lymphatic vessel images were clearly visualized in healthy limbs. Inguinal or axillary lymph nodes can be visualized when examined 30 minutes after injection. Lymphatic contraction frequency was 1(0.33-5.00)time per minute. 94.8% lymphedematous limb demonstrated delayed lymphatic vessel or lymph nodes. "Dermal backflow" and diffused shadow pattern can be observed in all affected limbs. Abnormal lymphatic vasculature and contraction can be visualized. The frequency of lymphatic contraction in the affected limb was higher compared to controls: 2.5(0.5-7.0) times per minute.@*Conclusions@#ICG lymphography possess high sensitivity for lymphedema diagnosis. ICG lymphography furthers our understanding of pathophysiological alterations of lymphatic disorders.
ABSTRACT
This study was to investigate the inhibitory effects of artemether in combination with etoposide on the proliferation and invasion ability of human small cell lung cancer cell line H446.H446 cells were treated with different concentrations of artemether or etoposide alone or their combination.The inhibitory effects on proliferation were detected by MTT assay,while cell cycle and apoptosis of H446 cells in each group were analyzed by flow cytometry using PI and Annexin V/PI-staining,respectively.The invasion capability of H446 cells in different groups was tested with matrigel-coated transwell.The results implicated that artemether or etoposide or their combination does inhibit proliferation of H446 cells dose-dependently.Artemether alone had little effect on the apoptosis of H446 cells while its combination with etoposide resulted in significantly apoptosis of H446 cells comparing with other groups (P ＜ 0.05).Etoposide blocked H446 progression markedly by arresting cell cycle in G2 phase with percentage of cells in G1 phase decreasing significantly while artemether alone or in combination with etoposide had little synergetic effect on cell cycle.Artemether or etoposite alone or their combination could dramatically inhibit the invasion ability of H446 cells.
ABSTRACT
A 2-month-and-20-day-old girl was hospitalized because of slow weight gain for 20 days.The patient was diagnosed as anemia,pneumonia and neutrophils firstly,and showed no improvement during anti-infective therapy,blood transfusion,and leukopenia drugs.The urinary organic acid spectrum of the patient showed increased methylmalonic acid slightly,but the normal value was found by 4 tests,which was inconsistent with the typical methylmalonic aciduria.By analyzing clinical manifestations and plasma homocysteine,folic acid and vitamin B12 levels,she was considered to have intracellular cobalamin metabolic disorder.Then,normal diet,intramuscular injection of vitamin B12,and feeding calcium,betaine,and L-carnitine were given,and the girl's symptoms were improved significantly.Latter gene analysis further showed that the patient had methylmalonic aciduria CblC type.Clinical manifestations of methylmalonic aciduria are complex and individually various,different therapies showed be applied to different causes.The value of urinary methylmalonic acid level alone cannot judge etiology;diagnosis should be based on blood amino acids and carnitine spectrum,homocysteine level and vitamin B12 level.

ABSTRACT
Objective To investigate the diagnostic value of dual-energy CT virtual non-contrast (VNC) technology for osteoporosis(OP). Methods Dual-energy CT images of 50 patients with lumbar traumas were collected prospectively.Patients who suffer from vertebral bodies fractures between lumbar 1 to 4, have internal metal fixations or underwent percutaneous vertebroplasty, or presented tumors or compromised bone metabolism induced by diseases or medications were excluded.The scanning range was from the upper edge of the 12th thoracic vertebral body to the lower edge of the first sacral vertebral body. The voltages of tubes A and B were 90 kV and Sn 150 kV,and the reference tubes currents were 220 mAs and 138 mAs. Image reconstruction was performed using Advanced Modeled Iterative Reconstruction (ADMIRE)with iterative strength of 3 and convolution kernel of Qr 40.The default parameters of the virtual non-contrast software were corrected by the standard recommended by the Bone Marrow software of the post-processing platform Syngo.via,and the CT value of calcium(contrast media CM),the CT value of mixed energy images(regular CT value,rCT),the calcium density(CaD)and the fat fraction(Fat)were measured. The bone mineral density (BMD) and T score of each lumbar vertebra from lumbar 1 to lumbar 4 were measured by dual energy X-ray absorptiometry(DXA).With T score less than or equal to the 2.5 standard deviation as the gold standard for the diagnosis of OP,correlations between CT measurements and vertebral BMDs were analyzed using Pearson correlation analysis and linear regression and the diagnostic values of different CT measurements for OP were compared using receiver operating characteristic curve. Results Each of the vertebral bodies was analyzed as a single unit.Fifty of them were osteoporotic and the rest 116 were non-osteoporotic.Except for Fat,the CT measurement parameters of the osteoporotic vertebral bodies were lower than those of the ones without osteoporosis, and the difference was statistically significant (P<0.01).CM,rCT and CaD were significantly correlated with BMD(r were 0.75,0.65,0.71,all P<0.01)and there was a linear relationship(F were 209.91,120.24,167.69,all P<0.01).Meanwhile,CM,rCT,CaD and T score were also significantly correlated (r were 0.74, 0.65, 0.70, all P<0.01) with a linear relationship (F were 195.04,120.29,156.37,all P<0.01).CM,rCT and CaD had relatively high concordance rates against the OP diagnosis gold standard (respectively 81.9%, 62.2% and 81.9%). CM and CaD had higher concordance rates than rCT,the difference being statistically significant(P<0.01),and by the CM less than 239.5 HU or CaD less than 10.9 mg/cm3standard, their sensitivities of diagnosing osteoporosis were respectively 86.0% and 84.0%,while the specificities,80.2% and 81.0%.After superimposing CM and CaD, the results did not improve the diagnosis efficiency of OP (pre-superposition diagnostic performance better than post-superposition (P<0.05). Conclusion The VNC technology on DECT can do both vertebral fractures diagnosis and osteoporosis assessment at the same time, thus optimizing the clinical examination process.
