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 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 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

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

@#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 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.

ABSTRACT

Objective@#To evaluate the efficacy and safety of Yupingfeng powder in conjunction treatment of western medicine on cough variant asthma (CVA).@*Methods@#We searched CNKI, Wanfang database, VIP database and PubMed through computer from the database building to October 31st 2017. The randomized controlled trails (RCT) with the comparison in the treatment of CVA with Yupingfeng powder and western medicinal were identified and included. The quality of RCTs was assessed by Jadad scores, and meta-analyses were performed by Review Manager 5.3 software.@*Results@#Totally 15 RCTs involving 1 318 patients were included into the study, which all belonged to the low methodological quality. The meta-analysis results showed that compared with the western medicine alone, the treatment in conjunction of Yupingfeng powder can significantly improve the clinical effective rate [OR=3.45, 95% CI (2.38-5.02), P<0.01], reduce the recurrence rate [OR=0.25, 95% CI (0.16-0.38), P<0.01]. There were no statistical significant differences with untoward effect between above two treatment groups [OR=0.70, 95% CI (0.34-1.46), P=0.35].@*Conclusions@#The Yupingfeng powder combined with the routine therapy may improve the clinical effective rate, and reduce the recurrence rate for CVA patients. However, we need more high-quality RCTs to comfirm such results.

ABSTRACT

Objective@#To explore the method of extracting chaperone antigen peptide complexes from gastric cancer stem cells and its immune function.@*Methods@#Gastric cancer stem cells and gastric cancer cells were screened by low temperature ultrasonic lysis. After salting out and dialysis, the lysate supernatant was processed with SDS-PAGE to analyze the expression of chaperone antigen peptide complexes, and then was separated and purified with CNBr-activated SepharoseTM 4B. Reverse high pressure liquid chromatography (HPLC), SDS-PAGE and Western blotting were used to analyze the purity and nature of the acquired albumen. Lymphocyte proliferation assay and lymphocytotoxicity assay were used to ditermine the immunological activity of the chaperone-antigen peptide complexes.@*Results@#The chaperone antigen peptide complexes of gastric cancer stem cells were prepared and identified successfully, of which the main components were the antigen peptides of HSP60, HSP70, HSP90 and HSP110. 0.75 μg and 1.00 μg HSP70-antigen peptide and 1.00 μg HSP90-antigen peptide activated lymphocytes significantly. Their A490 values were 0.26±0.03, 0.45±0.05 and 0.32±0.04, respectively, while the corresponding doses of HSP60-antigen peptide and HSP110-antigen peptide did not activate lymphocytes. The killing rates of 1.00 μg HSP70-antigen peptide and 1.00 μg HSP70 were (45.0±2.0)% and (16.0±2.0)%, respectively, showing a significant difference (P=0.012). Similarly, the killing rates of 1.00 μg HSP90-antigen peptide and 1.00 μg HSP90 were (36.0±5.0)% and (13.0±4.0)%, respectively, also showing a significant difference (P=0.048).@*Conclusions@#The amount of chaperone antigen peptide complexes in gastric cancer cells is extremely low, but it is obviously increased in gastric cancer stem cells. After purification, the chaperone antigen peptide complexes with high purity can be prepared. The extracted chaperone antigen peptide complexes have stronger immunogenicity, and can be used to make tumor vaccine in vitro, which may have a good application value in the targeted therapy of gastric cancer.

ABSTRACT

Objective To evaluate the diagnostic accuracy and efficacy on cervical precancerous lesions and cervical cancer by HPV 16/18 E6 protein detection. Methods A total of 439 females with sexual activities were selected from Department of Gynaecology in Shanxi Cancer Hospital from May 2014 to January 2015, including 299 cases of cervical intraepithelial neoplasia (CIN)Ⅱ, CINⅢ or cervical cancer (the case group), and the other 140 cases (the control group). All the patients accepted the thinprep cytology test (TCT), HPV DNA and HPV 16/18 E6 oncoprotein tests and colposcope examination. Results The positive rates of the TCT, HPV DNA, HPV 16/18 E6 oncoprotein in the case group were 97.0 % (290/299), 94.3 % (282/299) and 66.9 % (200/299), respectively, and those in the control group were 44.3 % (62/140), 21.4 % (30/140) and 2.9%(4/140), respectively, and there were significant differences between both groups (all P<0.05). The sensitivity and specificity of the HPV 16/18 E6 oncoprotein test in detecting CINⅡ and above were 66.9 %and 97.1 %, respectively, and both of HPV DNA test were 94.3 % and 78.6 %, respectively; The consistent rate between HPV 16/18 E6 and HPV DNA was 71.9 % (κ= 0.21). In the case group, when TCT was associated with HPV DNA test, the sensitivity, specificity and accuracy were 98.9%, 82.8%and 81.7%, respectively, and when TCT was combined with HPV 16/18 E6 oncoprotein test, those were up to 97.9 %, 97.1 % and 95.0 %. Conclusion HPV 16/18 E6 oncoprotein test can improve the specificity of cervical cancer screening, so it may be used as a primary screening method in the less developed areas where HPV DNA test is difficult to be carried out, or as a shunt method for HPV DNA positive patients, which will allocate the limited health resources rationally.
