ABSTRACT

Male reproductive infections are known to shape the immunological homeostasis of the testes, leading to male infertility. However, the specific pathogenesis of these changes remains poorly understood. Exosomes released in the inflammatory microenvironment are important in communication between the local microenvironment and recipient cells. Here, we aim to identify the immunomodulatory properties of inflammatory testes-derived exosomes (IT-exos) and explore their underlying mechanisms in orchitis. IT-exos were isolated using a uropathogenic Escherichia coli (UPEC)-induced orchitis model and confirmed that IT-exos promoted proinflammatory M1 activation with increasing expression of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in vitro. We further used small RNA sequencing to identify the differential miRNA profiles in exosomes and primary testicular macrophages (TMs) from normal and UPEC-infected testes, respectively, and identified that miR-155-5p was highly enriched in IT-exos and TMs from inflammatory testes. Further study of bone marrow derived macrophages (BMDMs) transfected with miR-155-5p mimic showed that macrophages polarized to proinflammatory phenotype. In addition, the mice that were administrated IT-exos showed remarkable activation of TM1-like macrophages; however, IT-exos with silencing miR-155-5p showed a decrease in proinflammatory responses. Overall, we demonstrate that miR-155-5p delivered by IT-exos plays an important role in the activation of TM1 in UPEC-induced orchitis. Our study provides a new perspective on the immunological mechanisms underlying inflammation-related male infertility.

ABSTRACT

Objective:To investigate the effects of Tiaogan Lifei Decoction on the level of symptom control in patients with bronchial asthma (asthma) treated with moderate and high dosage inhaled glucocorticoids (ICS).Methods:Randomized double-blind placebo controlled prospective study was used. Totally 90 patients with asthma (liver lung disharmony, wind phlegm blocking collateral syndrome) using moderate and high dosage ICS who met the inclusion criteria from January 2020 to December 2021 in Chaoyang District Hospital of Traditional Chinese Medicine in Beijing were divided into two groups according to random number table method, with 45 cases in each group. On the basis of using the original dosage of ICS, the treatment group used Tiaogan Lifei Decoction, while the control group used Tiaogan Lifei Decoction simulant. The course of treatment was 12 weeks. TCM symptom score of both group before and after the treatment was detected; asthma control test (ACT) was used to assess the effects of asthma on the patients; St George's Hospital Respiratory Questionnaire (SGRQ) was used to assess patients' quality of life; the peak expiratory flow rate (PEF) was measured with a peak expiratory flow meter. 2 ml of venous blood was collected for eosinophil (EOS) detection, and the serum allergen specific IgE level was determined by ELISA. The adverse reactions were observed during the treatment and the clinical efficacy was evaluated.Results:During the test, 3 cases and 2 cases in the treatment group and control group lost prevention respectively. 3 cases in the treatment group and 6 cases in the control group withdrew from the trial because of the aggravation of symptoms and the need to increase the dosage of ICS. The total effective rate in the treatment group was 78.6% (33/42), and that in the control group was 55.8% (24/43), with statistical significance ( χ2=4.98, P=0.026). After treatment, the scores of daily activities, early awakening, control and total scores in the treatment group were higher than those in the control group ( t values were 1.76, 1.99, 2.00, 2.69, respectively, P<0.01 or P<0.05); after treatment, the scores of cough, chest tightness, active wheezing, upset, pharyngeal itch and total score in the treatment group were lower than those in the control group ( t values were -5.89, -6.01, -5.66, -4.27, -6.67, -9.05, respectively, P<0.01); SGRQ score in the treatment group was lower than that of the control group ( t=-7.19, P<0.01). No serious adverse reactions occurred during treatment in the two groups. Conclusion:Tiaogan Lifei Decoction is helpful to improve the symptom control level of asthma patients who are using ICS, and effectively improve the quality of life of patients with asthma of liver lung disharmony and wind phlegm obstructing collaterals syndrome.

ABSTRACT

Objective: To summarize the clinical characteristics and gene variants of 2 pedigrees of non-muscle myosin heavy chain 9 related diseases (MYH9-RD) in children. Methods: The basic information, clinical features, gene variants and laboratory tests of MYH9-RD patients from 2 pedigrees confirmed in the First Affiliated Hospital of Zhengzhou University in November 2021 and July 2022 were analyzed retrospectively. "Non-muscle myosin heavy chain 9 related disease" "MYH9" and "children" were used as key words to search at Pubmed database, CNKI and Wanfang database up to February 2023. The MYH9-RD gene variant spectrum and clinical data were analyzed and summarized. Results: Proband 1 (male, 11 years old) sought medical attention due to epistaxis, the eldest sister and second sister of proband 1 only showed excessive menstrual bleeding, the skin and mucous membrane of the their mother were prone to ecchymosis after bumping, the uncle of proband 1 had kidney damage, and the maternal grandmother and maternal great-grandmother of proband 1 had a history of cataracts. There were 7 cases of phenotypic abnormalities in this pedigree. High-throughput sequencing showed that the proband 1 MYH9 gene had c.279C>G (p.N93K) missense variant, and family verification analysis showed that the variant was inherited from the mother. A total of 4 patients including proband 1 and family members were diagnosed with MYH9-RD. The proband 2 (female, 1 year old) sought medical attention duo to fever and cough, and the father's physical examination revealed thrombocytopenia. There were 2 cases of phenotypic abnormalities in this pedigree. High-throughput sequencing showed that there was a c.4270G>A (p.D1424N) missense variant in the proband 2 MYH9 gene, and family verification analysis showed that the variant was inherited from the father. A total of 2 patients including proband 2 and his father were diagnosed with MYH9-RD. A total of 99 articles were retrieved, including 32 domestic literatures and 67 foreign literatures. The MYH9-RD cases totaled 149 pedigrees and 197 sporadic patients, including 2 pedigrees in our study. There were 101 cases with complete clinical data, including 62 sporadic cases and 39 pedigrees. There were 56 males and 45 females, with an average age of 6.9 years old. The main clinical manifestations were thrombocytopenia, skin ecchymosis, and epistaxis. Most patients didn't receive special treatment after diagnosis. Six English literatures related to MYH9-RD caused by c.279C>G mutation in MYH9 gene were retrieved. Italy reported the highest number of cases (3 cases). Twelve literatures related to MYH9-RD caused by c.4270G>A mutation in MYH9 gene were retrieved. China reported the highest number of cases (9 cases). Conclusions: The clinical manifestations of patients in the MYH9-RD pedigrees varied greatly. MYH9 gene c.279C>G and c.4270G>A mutations are the cause of MYH9-RD.

ABSTRACT

Objective: To summarize the clinical data and prognosis of children with Philadelphia chromosome-like acute lymphoblastic leukemia (Ph-like ALL) common genes. Methods: This was a retrospective cohort study.Clinical data of 56 children with Ph-like ALL common gene cases (Ph-like ALL positive group) treated from January 2017 to January 2022 in the First Affiliated Hospital of Zhengzhou University, Henan Children's Hospital, Henan Cancer's Hospital and Henan Provincial People's Hospital were collected, 69 children with other high-risk B cell acute lymphoblastic leukemia (B-ALL) at the same time and the same age were selected as the negative group. The clinical characteristics and prognosis of two groups were analyzed retrospectively. Comparisons between groups were performed using Mann-Whitney U test and χ2 test. Kaplan-Meier method was used for survival curve, Log-Rank test was used for univariate analysis, and the Cox regression model was used for multivariate prognosis analysis. Results: Among 56 Ph-like ALL positive patients, there were 30 males and 26 females, and 15 cases were over 10 years old. There were 69 patients in Ph-like ALL negative group. Compared with the negative group, the children in positive group were older (6.4 (4.2, 11.2) vs. 4.7 (2.8, 8.4) years), and hyperleukocytosis (≥50×109/L) was more common (25% (14/56) vs. 9% (6/69)), the differences were statistically significant (both P<0.05). In the Ph-like ALL positive group, 32 cases were positive for IK6 (1 case was co-expressed with IK6 and EBF1-PDGFRB), 24 cases were IK6-negative, of which 9 cases were CRLF2 positive (including 2 cases with P2RY8-CRLF2, 7 cases with CRLF2 high expression), 5 cases were PDGFRB rearrangement, 4 cases were ABL1 rearrangement, 4 cases were JAK2 rearrangement, 1 case was ABL2 rearrangement and 1 case was EPOR rearrangement. The follow-up time of Ph-like ALL positive group was 22 (12, 40) months, and 32 (20, 45) months for negative group. The 3-year overall survival (OS) rate of positive group was significantly lower than the negative group ((72±7) % vs. (86±5) %, χ2=4.59, P<0.05). Compared with the 24 IK6-negative patients, the 3-year event free survival (EFS) rate of 32 IK6 positive patients was higher, the difference was statistically significant ((88±9) % vs. (65±14) %, χ2=5.37, P<0.05). Multivariate Cox regression analysis showed that the bone marrow minimal residual disease (MRD) not turning negative at the end of first induction (HR=4.12, 95%CI 1.13-15.03) independent prognostic risk factor for patient with Ph-like ALL common genes. Conclusions: Children with Ph-like ALL common genes were older than other high-risk B-ALL patients at diagnosis, with high white blood cells and lower survival rate. The bone marrow MRD not turning negative at the end of first induction were independent prognostic risk factor for children with Ph-like ALL common gene.

ABSTRACT

Cannabis sativa,with a long history of cultivation, is a traditional industrial crop widely used for food, textiles, and me-dicine. This study discussed industrial C. sativa and medicinal C. sativa. According to the characteristics of management policies of C. sativa in different periods, we divided the development stages of C. sativa into three stages and analyzed the changes in breeding and cultivation goals under the influence of policies. Meanwhile, a comprehensive analysis was carried out based on the breeding conditions of industrial C. sativa in China. Because of the vast territory of China, the differences in agricultural planting environment, economic development, and social development in the southern and northern areas result in different used parts of C. sativa. To be speci-fic, flowers and leaves are used in Yunnan, fiber in Heilongjiang, and seeds in Shanxi. The breeding of C. sativa varieties highlights fiber, seeds, or both of them. As the value of cannabidiol is explored, medicinal C. sativa has been approved in recent years. Based on the cultivation characteristics and value of industrial C. sativa, it is proposed that industrial C. sativa has a broad application prospect as an important industrial crop, and the existing products contain almost no tetrahydrocannabinol. The cultivation of C. sativa should be rationally guided to promote the development of the C. sativa industry. Moreover, it is recommended to actively apply advanced breeding techniques such as molecular breeding to overcome the problems of the uncertainty of the existing induced breeding and the excessively long hybrid breeding cycle, and develop high value-added applications such as medicinal products of C. sativa to enhance the exploitation of the economic value of C. sativa.

ABSTRACT

Objective: To investigate the clinical features, survival and prognostic risk factors of children with hepatoblastoma (HB). Methods: Clinical data of 83 children with newly treated HB at the Department of Hematology and Oncology, Children's Hospital, the First Affiliated Hospital of Zhengzhou University from January 2012 to October 2019 were analyzed retrospectively. The sex, age, first clinical manifestations, pretreatment extent of disease (PRETEXT) stages, pathological types, initial alpha-fetoprotein (AFP), treatment methods and treatment outcome of all patients were summarized. The children diagnosed before 2018 were treated with "Wuhan Protocol", and those who diagnosed after 2018 were treated with the "Expert Consensus for Multidisciplinary Management of Hepatoblastoma"(CCCG-HB-2016) protocol. Kaplan-Meier survival analysis was used to calculate the survival rate, Log-Rank test was used in univariate analysis, and the Cox regression model was used in multivariate prognosis analysis. Results: Among 83 cases, there were 51 males and 32 females. The age of onset was 25.2 (9.0, 34.0) months old, and 64 cases (77%) were under 3 years old. The most common first clinical manifestation was abdominal mass in 45 cases (54%). There were 8 cases of PRETEXT stage Ⅰ, 43 cases of stage Ⅱ, 20 cases of stage Ⅲ and 12 cases of stage Ⅳ. During the follow-up period of 40 (17, 63) months, the 1-year overall survival (OS) rate and event-free survival (EFS) rate were (84±4) % and (79±5) %, respectively, and 5-year OS rate and EFS rate were (78±5) % and (76±5) %, respectively. Fifty-five cases were treated with "Wuhan Protocol", and the 5-year OS and EFS rate were (73±6) % and (71±6) %, respectively. Twenty-eight cases were treated with CCCG-HB-2016 protocol, and the 5-year OS and EFS rate were (88±7) % and (82±9) %, respectively. Multivariate COX regression analysis showed that AFP did not turn negative after 3 courses of postoperative chemotherapy (HR=9.228, 95%CI 1.017-83.692) and PRETEXT stage Ⅳ (HR=6.587, 95%CI 1.687-25.723) were independent risk factors affecting the prognosis of children with HB. Conclusions: The "Wuhan Protocol" and CCCG-HB-2016 protocol were effective in the treatment of children with HB. AFP did not turn negative after 3 courses of postoperative chemotherapy and PRETEXT stage Ⅳ were independent risk factors affecting the prognosis of children with HB.

ABSTRACT

Objective:To realize the understanding level of cancer awareness of residents in Shanxi Province, and to provide a scientific basis for cancer prevention and treatment.Methods:In April 2020, 1 897 local residents in Shanxi Province were recruited to fill in the core knowledge questionnaire of cancer prevention and treatment. The basic demographic information and the core knowledge of cancer prevention and control were collected, and the influencing factors for the understanding of the core knowledge of cancer prevention and treatment were analyzed by using multivariate logistic regression model.Results:In the survey on the awareness rate of core knowledge of cancer prevention and control among residents in Shanxi Province, 37 940 items were answered, among which 29 396 items were known, and the awareness rate of the population was 77.48% (29 396/37 940). The single-factor results showed that there were statistically significant differences in awareness rates of core knowledge of cancer prevention and treatment among the population with different gender, household registration, ethnic groups, education degree, occupation and different frequency of the health examination were statistically significant (all P < 0.05); there were no statistically significant differences in awareness rates of core knowledge among the population with different age, and smokers or non-smokers (all P >0.05).Multivariate logistic regression analysis showed that education degree of junior middle school or above ( OR = 3.412-16.767, 95% CI 1.755-32.476) and receiving physical examination once a year ( OR = 2.291, 95% CI 1.154-4.549) were the favorable factors for knowing the core knowledge of cancer prevention and treatment. Household location in rural area ( OR = 0.522, 95% CI 0.378-0.722) and non-Han nationality ( OR = 0.369, 95% CI 0.151-0.904) were the unfavorable factors for knowing the core knowledge of cancer prevention and treatment. Conclusions:The awareness of core knowledge of cancer prevention and treatment among residents in Shanxi Province is good, so it is necessary to continue to strengthen the publicity of cancer prevention and control and improve the awareness of cancer prevention and control in the future.

ABSTRACT

Objective:To investigate clinical characteristics of bullous pemphigoid (BP) developing after the treatment with dipeptidyl peptidase-Ⅳ inhibitors (DPP4i) in patients with diabetes mellitus.Methods:A total of 116 inpatients with BP complicated by diabetes mellitus were collected from the Seventh People′s Hospital of Shenyang between January 2014 and December 2020, and divided into 2 groups: DPP4i-BP group treated with DPP4i before the onset of BP, and general BP group receiving no treatment with DPP4i. General clinical data, skin lesion area, laboratory indicators, treatment regimens, and prognosis were analyzed and compared between the above 2 groups, the time interval from the administration of DPP4i to the diagnosis of BP was recorded in the DPP4i-BP group. One-way analysis of variance was used to compare measurement data among multiple groups, two-independent-sample t test was used for comparisons between two groups, and paired t-test for intra-group comparisons before and after treatment; chi-square test was used to compare enumeration data between groups. Results:There were 32 patients aged 77.17 ± 15.32 years in the DPP4i-BP group, with a male-to-female ratio being 15∶17; there were 84 patients aged 76.65 ± 19.32 years in the general BP group, with a male-to-female ratio being 43∶41. The time interval from the administration of DPP4i to the diagnosis of BP was 14.61 ± 3.93 months in the DPP4i-BP group. The time interval for vildagliptin was the shortest (5.42 ± 2.84 months) , and there was a significant difference in the time interval among vildagliptin, sitagliptin, linagliptin and saxagliptin ( F= 8.93, P < 0.001) . The proportion of patients with severe BP was significantly higher in the DPP4i-BP group (16 cases, 50%) than in the general BP group (25 cases, 29.76%; Z= 2.63, P= 0.008) . There was no significant difference in the positivity rate of anti-BP180 antibody between the two groups ( χ2= 0.03, P= 0.870) . However, the level of anti-BP180 antibody was significantly higher in the DPP4i-BP group than in the general BP group before and after treatment ( P= 0.015, < 0.001, respectively) , and the decrease in the level of anti-BP180 antibody was significantly less in the DPP4i-BP group than in the general BP group after treatment ( t= 5.11, P < 0.001) . There was no significant difference in the average effective dose of glucocorticoids required to control the disease between the two groups ( t= 1.00, P= 0.322) . However, the DPP4i-BP group showed a significant increase in the average time required to control the disease and in the proportion of patients requiring combined treatment with immunosuppressants or other drugs compared with the general BP group ( t= 6.72, 10.05, P < 0.001,= 0.002, respectively) . Within 6 months after the start of systemic treatment, the recurrence rate was significantly higher in the general BP group (17 cases, 27.86%) than in the DPP4i-BP group (2 cases, 7.69%; χ2= 4.35, P= 0.037) ; at 6 months, the average dose of glucocorticoids was also significantly higher in the general BP group than in the DPP4i-BP group ( t= 7.04, P < 0.001) . Conclusions:Among the DPP4i hypoglycemic drugs, vildagliptin was the most common drug administrated by patients before the onset of BP, with the shortest interval from the administration to the onset of BP. DPP4i-BP may be difficult to control at the early stage, but the prognosis is good.

ABSTRACT

Objective:To explore the mechanism underlying microRNA (miR) -125a-mediated inhibition of proliferation of keratinocytes.Methods:After 24-hour pretreatment with interleukin (IL) -23, human HaCaT keratinocytes were divided into miR-125a group and miR-NC group transfected with a miR-125a overexpression plasmid and a control plasmid, respectively. Cell counting kit-8 (CCK8) assay was performed to evaluate the proliferative ability of HaCaT cells in the two groups at 0, 24, 48 and 72 hours after transfection, real-time fluorescence-based quantitative PCR to determine the mRNA expression of miR-125a and IL-23 receptors (IL-23R) in the two groups 24 hours after transfection, and Western blot analysis to determine the protein expression of IL-23R, Janus kinase 2 (JAK2) , protein kinase B (AKT) and phosphorylated AKT (p-AKT) in the two groups 48 hours after transfection. Dual-luciferase reporter assay was performed to verify the targeting relationship between miR-125a and IL-23R. Comparison of means between two groups was carried out by using t test, and changes in the proliferative ability of HaCaT cells over time were evaluated by using repeated measures analysis of variance. Results:After plasmid transfection, the relative expression of miR-125a was significantly higher in the miR-125a group (6.377 ± 0.745) than in the miR-NC group (0.700 ± 0.222; t=7.305, P=0.002) . At 0, 24 and 48 hours after transfection, there was no significant difference in cellular proliferative ability between the miR-125a group and the miR-NC group ( t=0.663, 0.623 and 1.930, respectively, all P > 0.05) ; at 72 hours after transfection, the cellular proliferative ability was significantly lower in the miR-125a group than in the miR-NC group ( t=4.407, P < 0.05) . The IL-23R mRNA expression was significantly lower in the miR-125a group than in the miR-NC group ( t=3.082, P < 0.05) . Compared with the miR-NC group, the miR-125a group showed significantly decreased protein expression of IL-23R, JAK2 and p-AKT ( t=11.715, 6.996, 12.424, P < 0.001,=0.002, < 0.001, respectively) . Dual-luciferase reporter assay showed targeted binding of miR-125a to IL-23R. Conclusion:MiR-125a may inhibit the proliferation of keratinocytes by negatively regulating the IL-23R/JAK2/AKT signaling pathway.

ABSTRACT

OBJECTIVE@#To investigate the expression and significance of B and T lymphocyte weakening factor (BTLA) in patients with chronic myelomonocytic leukemia (CMML).@*METHODS@#Real-time PCR was used to detect the expression of BTLA and its ligand HVEM mRNA in 11 patients with chronic myelomonocytic leukemia and 11 normal donors. Flow cytometry was used to detect expression of BTLA and its HVEM on the cell surface of peripheral blood T lymphocytes and γδ T cells.@*RESULTS@#The median values of BTLA and its ligand HVEM mRNA expression in peripheral blood of patients with CMML were 0.009% and 559.4%, respectively, which were significantly lower than those of normal controls (0.053% and 1031%)(P<0.001). The expression level of BTLA and HVEM on cell surface of peripheral lymphocytes was not significantly different from that in normal controls (P=0.3031 and 0.2576), however, the proportion of peripheral blood T lymphocytes in patients with CMML (median: 37.73%) was significantly lower than that in controls (median 69.23%)(P=0.0005). The expression of BTLA on the surface of γδ T cells in peripheral blood of patients with CMML (median: 23.26%) was significantly lower than that of the controls (median: 52.64%) (P<0.05), and there was no significant abnormality in HVEM expression (P=0.2791).@*CONCLUSION@#The expression of BTLA and its ligand HVEM, the proportion of T lymphocytes and the expression of BTLA on the surface of γδ T cells in patients with CMML are reduced. The effects of these abnormalities on T cell function and prognosis and efficacy of patients need to be further observed.

ABSTRACT

Objective To investigate the sexual behavior types, condom use and influencing factors of gonorrhea patients in Yunnan Province, and to provide evidence for the adjustment of sexually transmitted disease (STD) prevention and control strategy. Methods A cross-sectional study was carried out to investigate gonorrhea patients in 14 STD clinics in 7 more prevalent prefectures (cities) of Yunnan Province. A questionnaire survey was conducted to investigate the socio-demographic and sexual characteristics of the patients in a one-to-one way. Multiple Logistic regression model was used to analyze the influencing factors of sexual behavior. Results A total of 179 cases of gonorrhea were investigated. The average age was (29.01±8.93) years old. 95.53% (171/179) patients were 40 years old and 88.27% were male patients (158/179). Unmarried patients accounted for 55.31% (99/179). Service and self-employed patients accounted for 34.64% (62/179) and 23.46% (42/179) respectively. The rate of sexual intercourse with opposite sex was 98.32% (176/179), the rate of men who have sex with men was 1.68% (3/179) and the rate of having more than two sexual partners was 27.93% (50/179). The rate of sexual intercourse between temporary partners, spouses/fixed partners and commercial partners were 53.07% (95/179), 37.99% (68/179) and 8.94% (16/179) respectively. Recent sexual activity had lower condom use rate, 17.89% (17/95), 19.12% (13/68) and 18.75% (3/16) respectively. The main ways for gonorrhea patients to make temporary partners were friend introductions or gatherings, accounting for 66.32% (63/95). Condom use in male patients was worse than that in female patients (OR=0.234, 95% CI: 0.084-0.656, P=0.006). Conclusions The patients with gonorrhea were mainly unmarried young adults. The main risk behaviors were unprotected behaviors between heterosexual temporary and spouse/fixed sexual partners. The condom use consciousness was generally low. The promotion of safe sex education for young adults should be further strengthened, with special attention to the use of condoms for temporary sexual behavior and spouse/fixed sexual intercourse.

ABSTRACT

Objective:To investigate the correlation between microRNA-125a (miR-125a) expression and inflammatory cytokine levels in skin lesions of patients with psoriasis vulgaris, and to evaluate the effect of miR-125a on the proliferation of a human immortalized keratinocyte cell line HaCaT.Methods:Totally, lesional and adjacent non-lesional skin tissues were collected from 40 patients with psoriasis vulgaris in the Seventh People′s Hospital of Shenyang from 2017 to 2018, and real-time fluorescence-based quantitative reverse transcription PCR was performed to determine the expression of miR-125a in the skin tissues, as well as the mRNA expression of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6, and IL-17 in the lesional skin tissues. HaCaT cells were divided into 4 groups to be transfected with a miR-125a overexpression plasmid (miR-125a overexpression group), an overexpression control plasmid (overexpression control group), a miR-125a interference plasmid (miR-125a interference group) and an interference control plasmid (interference control group), respectively. Cell counting kit-8 (CCK8) assay was performed to assess the proliferative ability of HaCaT cells in the groups at 0, 24, 48, 72 hours after transfection, and double-antibody sandwich enzyme-linked immunosorbent assay (ELISA) to detect the levels of TNF-α, IL-1β, IL-6 and IL-17 in the culture supernatant of HaCaT cells. Spearman rank correlation test was used for correlation analysis, and t test for the comparison of means between two groups. Results:The relative expression of miR-125a was significantly lower in the lesional skin tissues (expressed as 2 -ΔΔCt, 0.389 ± 0.354) than in the non-lesional skin tissues (1.106 ± 0.396, t = 7.717, P < 0.001) in patients with psoriasis vulgaris. The expression of miR-125a was negatively correlated with the mRNA expression of TNF-α, IL-1β and IL-17 in psoriatic lesions ( r = -0.447, -0.424, -0.436, all P < 0.01). Immediately and 24 hours after transfection with the plasmids, there was no significant difference in the cell proliferative ability between the miR-125a overexpression group and overexpression control group ( t = 0.282, 1.445, respectively, both P > 0.05), or between the miR-125a interference group and interference control group ( t = 0.120, 1.543, respectively, both P > 0.05). Forty-eight and 72 hours after the transfection, the cell proliferative ability was significantly lower in the miR-125a overexpression group than in the overexpression control group ( t = 3.222, 4.563, respectively, both P < 0.05), but significantly higher in the miR-125a interference group than in the interference control group ( t = 3.036, 3.269, respectively, both P < 0.05). In addition, the miR-125a overexpression group showed significantly decreased levels of TNF-α and IL-1β compared with the overexpression control group ( t = 4.318, 3.813, respectively, both P < 0.05) . Conclusions:MiR-125a is lowly expressed in skin lesions of patients with psoriasis vulgaris. MiR-125a can inhibit the proliferation of keratinocytes, and may play a protective role in the occurrence and development of psoriasis.

ABSTRACT

@#Myasthenia gravis (MG) is a disease of neuromuscular junction and mainly autoimmune in aetiology. The state of thymus is a critical determinant for the prognosis. In this retrospective review study, we aimed at clarifying the relationship between the mode of clinical presentation of MG and the radiopathological classification of the thymus. We identified patients with MG from the database of our medical center from 1988 – 2017. The patients were classified into two groups according to their clinical presentation: those with a typical presentation with diurnal variation, and those with an atypical presentation of persistent weakness or respiratory failure from the beginning. The underlying thymic state was categorized into six groups: normal, abnormal by imaging (if no operation was performed), hyperplasia, benign thymoma, cortical type thymoma, and malignant thymoma. In total, 227 patients (133 females and 94 males) were included in the analysis, of whom 68% were classified into the typical presentation group. The atypical presentation correlated significantly with thymic categories (p = 0.014) and sex (p = 0.026) but not age at onset (p = 0.232). The atypical presentation was more common in the male patients and in those with thymic carcinoma.

ABSTRACT

Objective To observe the effects of apatinib in the treatment of advanced hepatocellular carcinoma associated with hepatitis B. Methods The clinical data of 72 patients with advanced hepatocellular carcinoma associated with hepatitis B admitted to the First Affiliated Hospital of Bengbu Medical College from January 2015 to May 2017 were retrospectively analyzed. Among them,37 patients were treated with apatinib once a day,as apatinib group;35 patients were treated with FOLFOX4(oxaliplatin + calcium folinate + 5-fluorouracil)palliative chemotherapy,as FOLFOX4 group. The objective response rate(ORR),disease con-trol rate(DCR),serum alpha fetal protein(AFP),improvement of clinical symptoms,Karnofsky functional status(KPS)score improvement rate,median progression-free survival(PFS),median overall survival(OS), and the incidence of adverse reactions from both groups were contrastively analyzed. Results The ORR of apa-tinib group(27. 03% ,10 / 37)was higher than that of FOLFOX4 group(17. 14% ,6 / 35),and DCR (64. 86% ,24 / 37)was also higher than that of FOLFOX4 group(48. 57% ,17 / 35). However,there were no significant difference in ORR and DCR between the two groups(χ2 = 1. 017,P = 0. 313;χ2 = 1. 948,P =0. 163). After 16 weeks of treatment,serum AFP of apatinib group[(280 ± 20)ng/ ml]was significantly lower than that in FOLFOX4 group[(450 ± 20)ng/ ml,t = 36. 049,P < 0. 001]. Improvement rate of KPS score(86. 49% ,32 / 37)was significantly more than that of FOLFOX4 group(57. 14% ,20 / 35;χ2 = 7. 720, P = 0. 006). Improvement rate of clinical symptoms(72. 97% ,27 / 37)was significantly more than that of FOLFOX4 group(42. 86% ,15 / 35;χ2 = 6. 712,P = 0. 010). The mean PFS of apatinib group was 6. 2 months,which was significantly longer than that of FOLFOX4 group(2. 8 months,χ2 = 4. 815,P = 0. 028). The mean OS of apatinib group was 10. 9 months,which was significantly longer than that of FOLFOX4 group (6. 6 months,χ2 = 26. 429,P < 0. 001). In apatinib group,the main adverse reactions were hypertension, proteinuria and hand-foot syndrome;and in FOLFOX4 group,the main adverse reactions were leukopenia,neu-rotoxicity and liver function damage. Moreover,the adverse reactions in both groups were mostly 1 or 2 grade, which could be relieved or improved through symptomatic treatment. Conclusion Apatinib is safe and effective in the treatment of advanced hepatocellular carcinoma associated with hepatitis B. It can significantly prolong the life of patients and improve the quality of life and the clinical symptoms of patients.

ABSTRACT

Objective: To investigate the effect of Liuwei Dihuangwan on connexin 32 (Cx32) in hepatoma cell line CBRH7919 and its gap junction intercellular communication (GJIC), and furthermore study its mechanism of enhancing the bystander killing effect of suicide gene therapy. Method: Liuwei Dihuangwan (32 g·kg·d-1) and the same volume of normal saline were given to the rats by intragastrical administration. Blood was taken to prepare the medicated serum of Liuwei Dihuangwan and blank control serum, respectively. The hepatoma cell line CBRH7919 were treated by control serum and medicated serum of Liuwei Dihuangwan in different concentrations. There were four groups in experiment:the blank control group (volume fraction of 10%), medicated serum high dose group of Liuwei Dihuangwan (the volume fraction of 10%), medicated serum middle dose group of Liuwei Dihuangwan (the volume fraction of 5%), and medicated serum low dose group of Liuwei Dihuangwan (the volume fraction of 2.5%). The expression levels of Cx32 protein and mRNA in hepatoma cell line CBRH7919 were detected by indirect immunofluorescence assay (ⅡA) and Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) assay. The fluorescence redistribution after photobleaching (FRAP) method was used to detect the function of GJIC of hepatoma cell line CBRH7919. Result: ① The indirect immunofluorescence assay (ⅡA) analysis indicated that as compared with the blank control group, the cx32 expression of CBRH7919 cells was up-regulated in a concentration-dependent manner in each dose group of the serum containing Liuwei Dihuangwan (PPPPConclusion: The mechanism of medicated serum of Liuwei Dihuangwan in enhancing the bystander killing effect of suicide geneis related to gap junction. Liuwei Dihuangwan may enhance the function of GJIC by increasing the localization of cx32 on the cell membrane of CBRH7919 cells and increasing the expression of cx32 mRNA and protein to achieve the synergistic action.

ABSTRACT

Objective To assess the prevalence of overweight and obesity among residents aged 35 years or older in Yuhuan county of Zhejiang Province and explore the associations of overweight and obesity with hypertension. Methods A cross-sectional study was conducted among 124 693 permanent residents aged 35 years or older, who were randomly selected using cluster sampling method from Yuhuan county. Results The prevalence of overweight and obesity was 34.53% and 10.18% among subjects, respectively. The overweight prevalence for male (35.56%) was higher than that for female (33.66%), whereas the obesity prevalence for female (11.26%) was higher than that for male (8.90%) (all P<0.05). The multivariate analysis showed that age, education, occupation, regular physical exercise, smoking, drinking and high-salt diet were possible factors for overweight and obesity (all P<0.05). After adjustment for covariates, compared to participants with normal weight, the multivariate logistic regression indicated that the adjusted odds ratio (OR) and their 95% confidential interval of overweight and obesity were 2.02 (95% CI:1.93-2.11) and 3.83 (95% CI:3.57-4.10) for hypertension in men, and were 1.94(95% CI:1.86-2.02)and 3.56(95% CI:3.35-3.77) in women, respectively. Conclusions The prevalence of overweight and obesity was high among residents aged 35 years or older in Yuhuan county, and they may relate to the increasing risk of hypertension.
