OBJECTIVE@#To investigate the role of relationship between the expression of miRNA181a-5p and imbalance of Treg/Th17 in the pathogenesis of primary immune thrombocytopenia(ITP), which contributes to clarify the mechanism of T cell immune imbalance in ITP patients.@*METHODS@#Peripheral blood was collected from 37 ITP patients, concluding 21 untreated patients and 16 effectively treated patients, and 19 healthy controls; Peripheral blood mononuclear cells (PBMC) were isolated and the expression of miRNA181a-5p and Notch1 was analyzed by RT-PCR. The proportion of Th17 subsets and Treg cells in the peripheral circulation was detected by flow cytometer (FCM). Clinical data of ITP group was collected, including age, platelet count and disease course.@*RESULTS@#The expression of miR-181a-5p was significantly decreased in ITP group than that of healthy control group (P＜0.01). After effective treatment, the expression of miR-181a-5p was significantly higher than that of ITP group (P＜0.05), but still significantly lower than that of healthy control group (P＜0.01); The expression of Notch1 was significantly increased in ITP group and effectively treated group than that of healthy control group (P＜0.01). There was no significant difference in proportion of Treg cells in ITP group, effectively treated group and healthy control group (P＞0.05). The proportion of Th17 subsets in ITP group was significantly increased than that of healthy control group (P＜0.05), while the ratio of Treg/Th17 was significantly decreased (P＜0.05). There was a positive correlation between the expression of miR-181a-5p and ratio of Treg/Th17 in ITP group (r=0.555).@*CONCLUSION@#The expression of miR-181a-5p is significantly decreased in ITP patients, which is closely related to the imbalance of Treg/Th17 cells. After effective treatment, the expression of miR-181a-5p can be significantly corrected, but still failed to reach the level of healthy people. While the expression of Notch1 is significantly increased in ITP patients, and could not reach the level of healthy people after effective treatment.

Research progress on the regulation and mechanism of reactive oxygen species on tumor immune checkpoints / 药学学报

Immune checkpoints (ICs) are immunosuppressive molecules expressed on immune cells, which can regulate immune cells' activation. Immune checkpoint inhibitors (ICIs) which can block the interaction of immune checkpoints and their ligands, improve the cytotoxic effect of the immune system on tumor cells. Immunotherapy such as employing ICIs has gradually become a conventional therapeutic strategy for cancer treatment. However, the low response rate and the emergence of drug resistance have seriously affected the clinical efficacy of ICIs. Reactive oxygen species (ROS) are electronic reduction products of active oxygen, as well as natural by-products of cell metabolism, which can be used as regulators of intercellular signals. Tumor microenvironment (TME) is often in the state of oxidative stress (OS), which is the imbalance between oxidative system and antioxidant system. ROS can affect the interaction with its ligands by regulating the expression and activity of immune checkpoints in TME, thus affecting the anti-tumor effect of immune cells. Accumulating studies have shown that ROS could regulate tumor immune checkpoints through several pathways. Due to different types and stages of tumor, it would be clinical beneficial to understand the mechanistic link of ROS on tumor immune checkpoint, and choose appropriate ROS regulators combined with immune checkpoint inhibitors to maximize anti-tumor effects. This article reviews the common metabolic sources and characteristics of ROS, the regulatory effect and mechanism of ROS on tumor immune checkpoints and its therapeutic application.

Mechanism of tanshinone IIA to prevent spontaneous breast cancer in mice / 药学学报

To explore the effect of tanshinone IIA (TanIIA) on the occurrence and development of breast cancer, we employed the mouse mammary tumor virus-polyomavirus middle T antigen (MMTV-PyMT) transgenic mice as a spontaneous breast cancer mouse model. Animal welfare and experimental procedures were in accordance with the regulations of the Animal Ethics Committee of Nanjing University of Chinese Medicine. The animals were divided into control group, low-dose TanIIA treatment group (30 mg·kg-1·day-1), and high-dose TanIIA treatment group (60 mg·kg-1·day-1). The treatment was administered orally and daily for 5 weeks. The mice were sacrificed after final treatment. Mammary gland and lung were collected for histopathology studies. We evaluated the chemoprophylaxis effect of TanIIA on breast cancer in mice according to the pathological characteristics of breast cancer at different stages of development. Immunofluorescence staining were employed for blood vessel analysis. The expression levels of E-cadherin, proliferating nuclear antigen (PCNA), and oncogene c-Myc were detected by immunohistochemistry. Flow cytometry was used to analyze cell cycle and Cytoscape was used to construct drug-disease protein-protein interaction (PPI) network. Our results showed that TanIIA inhibits breast tumor progression by delaying malignancy from adenoma to early carcinoma, and inhibits blood vessel formation during tumor development. TanIIA (60 mg·kg-1·day-1) inhibits the expression levels of PCNA and c-Myc, upregulates the expression of E-cadherin. In addition, cell cycle experiments showed that the cell cycle of PyMT primary mammary cells in the high-dose TanIIA group was arrested in the G0/G1 phase. Our study demonstrated that TanIIA can significantly inhibit breast tumor progression in MMTV-PyMT mouse model, which may be related to the inhibition of angiogenic switch and cell cycle arrest.

OBJECTIVE@#To study the effect of astragaloside IV (AS-IV) on NOD-like receptor protein 3 (NLRP3) inflammasome in neonatal rats with hypoxic-ischemic brain damage (HIBD).@*METHODS@#A total of 24 Sprague-Dawley rats, aged 7 days, were randomly divided into a sham-operation group, an HIBD group, and an AS-IV treatment group, with 8 rats in each group. After 24 hours of modeling, brain tissue was collected for hematoxylin-eosin staining, yo-PRO-1 staining, and EthD-2 immunofluorescent staining in order to observe the cerebral protection effect of AS-IV in vivo. HT22 cells were used to prepare a model of oxygen-glycogen deprivation (OGD), and a concentration gradient (50-400 μmol/L) was established for AS-IV. CCK-8 assay was used to measure the viability of HT22 cells. RT-PCR and Western blot were used to observe the effect of different concentrations of AS-IV on the mRNA and protein expression of NLRP3, gasdermin D (GSDMD), caspase-1, and interleukin-1β (IL-1β).@*RESULTS@#Yo-Pro-1 and EthD-2 staining showed that compared with the sham-operation group, the HIBD group had an increase in pyroptotic cells with a small number of necrotic cells, and the AS-IV group had reductions in both pyroptotic and necrotic cells. Compared with the sham-operation group, the HIBD group had significantly higher protein expression levels of NLRP3, IL-1β, caspase-1, and GSDMD (@*CONCLUSIONS@#AS-IV may alleviate HIBD in neonatal rats by inhibiting the expression of NLRP3, GSDMD, caspase-1, and IL-1β.

Effects of electroacupuncture of different frequencies on electromyography, NOS and ICC of colon in rats with slow transit constipation / 针灸推拿医学（英文版）

Objective: To observe the effects of electroacupuncture (EA) of different frequencies on transmission function, electromyography, nitric oxide synthase (NOS) content and interstitial cells of Cajal (ICC) expression of colon in rat models with slow transit constipation (STC). Methods: Of the 50 healthy male Wistar rats, 10 were randomly selected as a normal group and fed with ordinary diet, and the remaining 40 rats were fed with the diet added with the compound diphenoxylate at a dose of 8 mg/(kg·bw) each day for continuous 120 d. The 40 successfully established STC rat models were randomly divided into a model group, a low-frequency EA group (2 Hz), a high-frequency EA group (100 Hz), and a variable-frequency EA group (2 Hz/100 Hz), with 10 rats in each group. Rats in the normal and the model groups were not given any treatment; the low-frequency EA and the high-frequency EA groups were given EA at Tianshu (ST 25), Zusanli (ST 36) and Zhigou (TE 6) with continuous wave at the designated frequency, and the variable-frequency EA group received sparse-dense wave (2 Hz/100 Hz) EA at the same acupoints, once a day for a total of 15 d. After treatment, the colonic transmission function, electromyography, NOS content and ICC expression (calculated by the difference in the area of the C-kit positive cells) of the rats in each group were measured. Results: For the colonic transmission function, compared with the normal group, the first black stool excretion durations of rats in the other groups were significantly prolonged (all P<0.05); compared with the model group, the first black stool excretion durations of rats in the three EA groups were significantly shortened (all P<0.05), which was significantly shorter in the variable-frequency EA group than in the low-frequency EA and high-frequency EA groups (both P<0.05). For the colonic electromyography, compared with the normal group, the amplitude was significantly increased and the frequency was accelerated in rats of the other groups (all P<0.05); compared with the model group, the amplitude was significantly reduced and the frequency was slowed down in the three EA groups (both P<0.05); compared with the low-frequency EA and the high-frequency EA groups, the amplitude was reduced and the frequency was significantly reduced in rats of the variable-frequency EA group (both P<0.05). Compared with the normal group, the colonic NOS contents were significantly increased in the other groups (all P<0.05); compared with the model group, the NOS contents were significantly reduced in the three EA groups (all P<0.05); compared with the low-frequency EA and the high-frequency EA groups, the content was significantly reduced in the variable-frequency EA group (all P<0.05). For the area of rat colonic C-kit-positive cells, compared with the normal group, the areas were significantly reduced in rats of other groups (all P<0.05); compared with the model group, the areas were increased significantly in the three EA groups (all P<0.05); compared with the low-frequency EA group, the area was increased significantly in the variable-frequency EA group (P<0.05). Conclusion: EA, especially EA at the 2 Hz/100 Hz variable-frequency, has a positive treatment effect on the STC model rats. It may improve rats' colonic function by regulating the electromyography, NOS content and ICC expression of colon.

Effects of ER Stress and PUMA on 5-FU-induced Liver Cell Injury and Apoptosis / 中山大学学报(医学科学版)

@#【Objective】To investigate the role of ER stress and PUMA in 5-FU-induced liver cells injury and apoptosis.【Methods】We established 5-FU-induced liver injury models by intraperitoneally injecting the isodose 5-FU to 10 PUMA knockout mice(PUMA-KO)and 20 PUMA Wild type mice(PUMA-WT). Meanwhile,10 WT mice were intraperitoneally injected with 4-Phenylbutyric acid,the ER stress inhibitor. In the control group,10 KO mice and 20 WT mice were given the same amount of normal saline.After the modeling,serum and liver tissues of the mice were collected to assess the degree of liver pathological injury,measure the expression levels of ALT and AST in serum,and detect the expression levels of PUMA and GRP78 in liver tissues. The changes of these indicators in different treatment groups were observed and compared.【Results】Compared with the WT control group,serum ALT and AST levels were significantly increased in the 5-FU group,H&E staining showed punctate focal necrosis,accompanied by hemorrhage and inflammation. TUNEL staining showed apoptotic cells were markedly added(Z = 3.78,P < 0.001),and expressions of PUMA and GRP78 were obviously augmented,suggesting that both PUMA and ER stress were involved in 5-FU-induced liver cells injury and apoptosis. Then,in the 4-PBA group,we found that the expression levels of GRP78 and PUMA were down-regulated,and apoptosis of liver cells was reduced under the same dose of 5-FU(χ~2= 32.99,Z = 3.78,P <0.001),further confirming that both PUMA and ER stress were involved in this process. Subsequently,it was found that,when induced by the same dose of 5-FU,cleaved caspase-3 staining showed that the liver apoptosis signal of the PUMA knockout mice was lower than the WT mice(χ~2= 33.99,Z = 3.78,P < 0.001),but the difference in the expression of GRP78 between the two groups was not statistically significant. In summary,the expression of PUMA was reduced and the apoptosis of liver cells was attenuated after the inhibition of ER stress;PUMA knockdown could not influence the activation of ER stress but alleviated apoptosis of liver cells.【Conclusions】PUMA mediates ER stress-up-regulated liver cells apoptosis in 5-FU-induced Chemotherapeutic liver injury.

Family history of rheumatic diseases in patients with rheumatoid arthritis: a large scale cross-sectional study / 北京大学学报(医学版)

OBJECTIVE@#To determine the associations between the family history of rheumatic diseases and clinical features in patients with rheumatoid arthritis (RA).@*METHODS@#In total, eight hundred and ninety patients with RA were enrolled. The demographic and clinical data were collected, including gender, age, height, body weight, age of disease onset, history of smoking and drinking, family history of rheumatic diseases, clinical and laboratory features, pain and global visual analogue scale (VAS), and multi-dimensional health assessment questionnaire (MDHAQ). Finally, 803 patients were completed the dataset and were included in the study.@*RESULTS@#In this cohort, the male/female ratio was 1:3.5, and the age of onset was (45.09±14.50) years. A total of 123 (15.32%) patients were accompanied with family history of rheumatic diseases, including RA, spondyloarthritis, Sjögren's syndrome, systemic lupus erythematosus and systemic sclerosis. The percentages of first degree, second degree and both first and second degree relatives were 91 (73.98%), 22 (17.89%), and 10 (8.13%) respectively. The most common disease was RA (70.73%), followed by other rheumatic diseases (21.95%), and RA combined with other rheumatic diseases (7.32%). The clinical and laboratory characteristics were compared between the patients with and without family history. The onset-age of the subjects was significantly different between those with and without family history of rheumatic diseases (39.97 ±13.68 vs. 46.01±14.46; P<0.01), which meant that the onset-age in patients with family history was 6.04 years earlier than that in patients without family history. The patients with family history had higher positive rate of rheumatoid factor (RF) compared with those without family history (78.48% vs. 66.67%, P<0.05). By adjusting with gender, body mass index (BMI), smoking and alcohol drinking, anti-cyclic citrullinated peptide (CCP) antibody and RF level, the age at disease onset in the patients with family history was 4.54 years earlier than that in the patients without family history (β=-4.54; 95%CI:-8.70, -0.38; P<0.05). Further hierarchical regression analysis showed that, the age at onset of the RA patients with family history was 10.02 years earlier than that without family history among the smoking patients (β= -10.02; 95%CI:-17.60, -2.43; P=0.01), while the age at onset of the RA patients with family history was 3.27 years earlier than that without family history among the never smoking patients (β=-3.27; 95%CI:-8.37, 1.82; P=0.21).@*CONCLUSION@#The family history of rheumatic diseases is a risk factor for early onset of RA, and may interact with smoking.

Platelet-rich plasma combined with naringin induces osteogenic differentiation of human bone marrow mesenchymal stem cells in vitro / 中国组织工程研究

BACKGROUND: Platelet-rich plasma (PRP) and naringin can both promote proliferation and induce osteogenic differentiation of mesenchymal stem cells. However, their combined use is rarely reported. OBJECTIVE: To observe the effect of PRP combined with naringin on the osteogenic differentiation of human bone marrow mesenchymal stem cells(hBMSCs)in vitro. METHODS: BMSCs at passage 3 were divided into four groups: (1) blank control group, cells were cultured in α-MEM; (2) PRP group, cells were cultured in α-MEM containing PRP; (3) naringin group, cells were cultured in α-MEM containing naringin; and (4) combined group, cells were cultured in α-MEM containing PRP and naringin. The contents of used PRP and naringin were 12.5% and 50 μg/L respectively. Cell proliferation was detected by MTT assay. Expression of related genes in hBMSCs was detected by RT-PCR. Alkaline phosphatase staining, collagen type I immunohistochemical staining, and alizarin red staining were used to analyze the osteogenic differentiation of hBMSCs. RESULTS AND CONCLUSION: The proliferation of hBMSCs was increased in each group, especially in the combined group. Cells in all the groups except the blank control group were positive for alkaline phosphatase staining, collagen type I immunohistochemical staining, and alizarin red staining, and the positive effect was more obvious in the combined group. However, negative or weakly positive response was found in the blank control group. At 7 and 14 days, the expression of alkaline phosphatase and collagen type I was significantly higher in the PRP, naringin and combined groups than the blank control group (P < 0.05); at 14 days, the expression of alkaline phosphatase and collagen type I was significantly higher in the combined group than the PRP and naringin groups (P < 0.05). To conclude, PRP combined with naringin can promote the proliferation of hBMSCs and induce the osteogenic differentiation of hBMSCs. Moreover, there is a synergistic effect between PRP and naringin.

OBJECTIVE: To investigate the potential effect of relaxin family peptide receptor 1( RXFP1) in the process of silica-induced silicosis. METHODS: Sixty-four specific pathogen free male Wistar rats were randomly divided into control group and experimental group. By one time intratracheal infusion,rats in experimental group were treated with 0. 1 m L 500 g / L silica dust suspension while the control group was treated with 0. 1 m L sodium chloride physiological solution. Eight rats from each group were sacrificed on day 1,7,14 and 28 after exposure. Histopathologic changes of the lung tissue were performed with hematoxylin-eosin staining. The expressions of Rxfp1 mRNA and RXFP1 protein in rat lungs were detected by real-time polymerase chain reaction and immunohistochemical staining,respectively. RESULTS: After 28 days of exposure,the grey nodules were observed by naked eye in the lung of the experimental group. The fracture and silicotic nodules could be seen in alveolar interval with light microscope. Compared with the control group,the Rxfp1 mRNA relative expression level in the lungs of experimental group was increased to 145% after 1 day of exposure( P < 0. 01),followed by a decrease on day 7 and 14 and reached similar level of control group( P > 0. 05). By day 28,it dropped to45% of control group( P < 0. 01). The RXFP1 protein relative expression in experimental group was significantly up-regulated since the 7th day compared to that of the control group( P < 0. 01). And it reached to the highest level on the28 th day( P < 0. 01). CONCLUSION: The RXFP1 might play an important role in inhibiting silicosis.

Expressions of FOXC1 and MMP-7 in molecular subtypes of breast cancer and their association with clinicopathological characteristics / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To investigate the expressions of FOXC1 and matrix metalloproteinase 7 (MMP-7) in different molecular subtypes of breast cancer and their association with clinicopathological characteristics of the disease.</p><p><b>METHODS</b>Based on immunohistochemical results of ER, PR, HER2, CK5/6, CK14 and EGFR, 105 breast cancer patients were classified as 4 subtypes: luminal, HER2 positive, basal-like subtype (BLs) and normal breast-like subtype (NBLs). The association of FOXC1 and MMP-7 expressions with clinicopathological parameters in different molecular subtypes was analyzed.</p><p><b>RESULTS</b>Out of 105 patients with breast cancer, the subtypes of luminal, HER2 positive, BLs and NBLs accounted for 52.4% (55/105), 16.2% (17/105), 17.1%(18/105) and 14.3% (15/105), respectively. Patients with luminal and/or NBLs subtypes had significantly higher 5-year survival rate than those with HER2 positive and/or BLs did (log-rank=22.161, P<0.01). The overall positive expression rate of FOXC1 was 26.7% (28/105) and the expression was higher in BLs patients than that in other subgroups (χ²=30.108, P<0.01). The expression of FOXC1 was correlated with histological grade, tumor size, distant metastasis and 5-year survival rate of breast cancer. The overall positive expression rate of MMP-7 was 67.6% (71/105) and the expression of MMP-7 was also higher in BLs patients than that in other molecular subtypes (χ²=11.328, P<0.05). The positive expression of MMP-7 was correlated with metastasis in ipsilateral axillary lymph nodes, distant metastasis and 5-year survival rate of the patients. FOXC1 was correlated with MMP-7 (r=0.325, P<0.01).</p><p><b>CONCLUSION</b>Patients with luminal and/or NBLs breast cancer have more favorable prognosis than those with HER2 positive and/or BLs subtypes. The expressions of FOXC1 and MMP-7 are closely correlated with the clinicopathological features of breast cancer patients.</p>

Comparison of different moxibustion techniques in clinical treatment of diseases based on data mining / 中国针灸

<p><b>OBJECTIVE</b>To explore the specific efficacy of different moxibustion techniques in treatment of common diseases and clinical indications, and compare the specificity in clinical indications and efficacy among different moxibustion techniques so as to guide clinical practice better.</p><p><b>METHODS</b>The modern computerization and data mining technology were adopted to set up moxibustion literature database. The relevant literature of moxibustion techniques in recent 60 years were collected, screened, examined, extracted and analyzed statistically so as to explore the advantages of different moxibustion techniques in clinical treatment.</p><p><b>RESULTS</b>(1) Of 2,516 literature, moxa stick, moxe cone and moxa device were used in the highest frequency in internal medicine department, for 730 times, 278 times and 102 times respectively. The warm needling technique was used in the highest frequency, for 70 times in the surgical department. (2) In the dermatology department, the curative rate with moxa cone was the highest, 75%. In the ear-nose-throat department, the warm needing technique and moxa device achieved the highest curative rate, 49% for both of them. In the internal medicine department and surgical department, the curative rate of warm needling technique was 53% and 58% respectively. In the gynecology department, the curative rate of moxa device was the highest, 59%. In the pediatrics department, the curative rate of moxa cone was the highest, 80%. (3) The numbers of priority disorders, frequency ≥20 times: 24 kinds of disease for moxa stick, five kinds of disease for moxa cone, 2 kinds of disease for warm needling technqiue and one disorder for moxa device. Facial paralysis, diarrhea, lumbar and leg pain and elbow and knee swelling pain were of the highest priority, treated with these 4 moxibustion techniques, with a certain of literature research values. (4) The warm needling technique achieved the better efficacy on elbow and knee swelling pain, lumbar and leg pain and diarrhea compared with the other three techniques and the curative rate was higher. The moxa device tecnique achieved the higher curative rate for facial paralysis compared with the other three techniques.</p><p><b>CONCLUSION</b>Through the comparison of application frequency, curative rate, clinical application frequency in disorders and the efficacy of priority disorders in the treatment with different moxibustion techniques, it is found that moxa stick, moxa cone and moxa device are simple in manipulation, safe and effective. Hence, they can be extensively used in the treatment of common disorders in every department in clinic. The warm needling technique acts on the body by the co-work of needling and warming stimulation of mugwort. It achieves the particular effect on the disorders with complicated etiologies compared with the other three techniques. It can be chosen in priority for the disorders caused by blockage in meridian and collateral and stagnation of qi and blood.</p>

Research of bleeding volume and method in blood-letting acupuncture therapy based on data mining / 中国针灸

Through computer-based technology and data mining method, with treatment in cases of bloodletting acupuncture therapy in collected literature as sample data, the association rule in data mining was applied. According to self-built database platform, the data was input, arranged and summarized, and eventually required data was acquired to perform the data mining of bleeding volume and method in blood-letting acupuncture therapy, which summarized its application rules and clinical values to provide better guide for clinical practice. There were 9 kinds of blood-letting tools in the literature, in which the frequency of three-edge needle was the highest, accounting for 84.4% (1239/1468). The bleeding volume was classified into six levels, in which less volume (less than 0.1 mL) had the highest frequency (401 times). According to the results of the data mining, blood-letting acupuncture therapy was widely applied in clinical practice of acupuncture, in which use of three-edge needle and less volume (less than 0.1 mL) of blood were the most common, however, there was no central tendency in general.
