SOMATIC EMBRYOGENSIS RECEPTOR KINASE （SERK） gene is known to function in SE. A homolog GhSERK2 （accession number： JF430801） was cloned from Upland cotton and characterized for its functions in SE. GhSERK2 expressed in different tissues and showed higher expression level in floral organs than vegetative ones with the highest levels in ovule and anther. GhSERK2 expressed during SE with a high level at globular embryos stage. Upon treatment with indole-3-butytic acid （IBA）, the transcription level of GhSERK2 was induced and promoted SE subsequently. A 2-day treatment of 2,4-dichlorophenoxyacetic acid （2,4-D） induced the expression of GhSERK2, but treatments of 2,4-D for longer periods sharply inhibited the GhSERK2 transcription level of embryogenic callus （EC）. The levels of hormones, including 3-indoleacetic acid （IAA）, abscisic acid （ABA）, and brassinosteroid （BR）, were increased in the initial calli induced from the over-expression of GhSERK2 cotton. Our results indicated that GhSERK2 expression was associated with induction of SE and closely related to hormone levels during tissue culture in Upland cotton, and the gene might play an important role in regeneration of cotton.展开更多

Kidney asthenia lasting for a long time will result in blood stasis. Also, the cause of VD may have relationships with endothelin (ET), nitric oxide (NO), homocysteine (HCY), estrogen (E2), and testosterone (T). OBJECTIVE: To observed clinical curative effect of the kidney tonic, pancreas tonic, and blood tonic with promoting blood circulation components in treating kidney asthenia with blood stasis syndrome of VD. DESIGN: Case controlled study. SETTING: Geriatric Institute of Integrated Medicine, Fujian College of Traditional Chinese Medicine. PARTICIPANTS: A total of 70 patients, including 39 males and 31 females aged 60-80 years, were selected from Department of Neurology, Pingshan Hospital from May 2000 to September 2002. Diagnostic criteria were used for probable VD of the American Psychiatric Association. Diagnostic and Statistical of Manual of Mental Disorder, 4th ed (DSM-Ⅳ), 1994 revised, mini-mental state examination (MMSE), and criteria of kidney asthenia with blood stasis with mixed weak and sthenia syndrome of Guidelines of Clinical Research of New Chinese Medicine in Treating Dementia. According to score of kidney asthenia with blood stasis syndrome, they were classified to three groups: mild (n =22), moderate (n =33) and severe (n =15). All of them with complete chest X-Ray, ECG, blood chemistry and other related examinations, exclusive of cardiovascular, liver, kidney diseases, homeopathy and psychiatry diseases. And hereby we also select 30 normal people as the comparing group, having no substantial diseases in heart, brain, kidney, liver, lung and other main organic systems after medical examination. Of this group, 11 were males and 19 were females, ranging from 62 years old to 78 years old. There were no obvious differences between the above two groups in sex, age, and education level after statistical analysis. All patients observed in Pingxi Hospital, Fuzhou, from May 2000 to September 2002. METHODS: ① According to the diagnoses standard of blood stasis syndrome: 0-89: The increase in score indicated that blood stasis syndrome was getting serious. ② According to MMSE: All the test samples were evaluated, those with scores of 0-30, in which the non-educated ≤ 17, primary school ≤ 20, above middle school ≤ 24 were categorized. ③ Testing all sample's ET, E2 and T by using radioimmunoassay, the RIA kits were provided by Scientific and Technological Development Center of General Hospital of PLA. ④ Testing the level of NO by using colorimetic method. ⑤ Testing the level of HCY by using Enzyme-linked Immunoassay. ⑥ Meanwhile, analyzing the blood stasis score by comparing with every standard. The differences of data were compared by using t test and F test. MAIN OUTCOME MEASURES: ① Blood plasma ET, blood serum NO, HCY, E2 and T. ② The analyzing results obtained from comparing score of blood stasis with every indicators. RESULTS: The result analysis was including of both the 70 patients of VD with kidney asthenia and blood stasis and compared group consist of 30 healthy people. ① ET, NO, HCY and ET/NO: The levels of ET, HCY and ET/NO were increasing with pathography, while the levels of ET, NO, HCY and ET/NO were decreasing with the pathography, and the difference in statistics was significant (P < 0.01). ② The level of E2 and T: The levels of both E2, T and E2/T for male VD patients were (67.72±12.18) pg/L and (351.58±155.02) ng/L, 0.24±0.12 respectively, which were higher than the compared group [(53.96±16.13) pg/L, (471.83±143.99) ng/L, 0.12±0.00, P < 0.05]. The level of E2 in the female VD patients was lower than the compared group [(34.23±10.99), (44.81±14.65) pg/L, P < 0.05]. ③ The relationship between the score of blood stasis and each indicators: The levels of ET, ET/NO and HCY had significant positive relationship with blood stasis mark (r = 0.352, 0.754, 0.347, P < 0.05-0.01), obvious negative relationship with NO (r =-0.528, P < 0.01) and no clear relationship with female E2/T and male E2/T (r = -0.210, 0.04, P > 0.05). CONCLUSION: ① The levels of ET, HCY and ET/NO are increasing with pathography, while the level of NO is decreasing, which may be the evidence that the possibility of VD pathography may have relationship with the indicators above. ② The level of E2 increase in male's VD patients, and decrease in male's. And the decrease of the female may have relationship with the VD.展开更多

In this study the effects of consumption of raw garlic on serum lipid level, blood sugar and a number of effective hormones on lipid and sugar metabolism (thyroid hormones and insulin) in individuals either with high level of blood sugar or lipid were investigated. Eighty five volunteers having following clinical history enrolled in the study: Group 1: having blood sugar more than 126 mg/dl (30 vo-lunteers);Group 2: having cholesterol higher than 245 mg/dl (30 volunteers);Group 3: having blood sugar over 126 mg/dl and cholesterol more than 245 mg/dl (25 volunteers). In group 1, there wasn’t a sig-nificant differences between biochemical factors be-fore and after garlic consumption, whereas, in the second group after 6 weeks of garlic consumption a decline in cholesterol (P < 0.001), FBS and TG (P < 0.01) was observed but HDL-C (P < 0.001) was in-creased. Six weeks after termination of garlic con-sumption, cholesterol (P < 0.001), FBS and TG (P < 0.05) were in- creased and HDL-C (P < 0.01) was de-creased. In the third group, total cholesterol (P < 0.001), FBS (P < 0.01) and HbA1c decreased while HDL-C was in- creased. Other factors, including thy-roid hormones (T3, T4), TSH and insulin showed no significant alte- ration. In conclusion our results shown that raw garlic consumption can reduce the FBS and Lipid in hyperglycemic and/or hyperlipidemic individuals.展开更多

And sex hormone level disorder has became a hot research topic in the pathogenesis of acne. Studies show that the biological clock disorder can result in the disorder of sex hormone levels which causes or aggravates acne. Biological clock disorder coincides naturally with "sleep rhythm disorder" in Traditional Chinese Medicine(TCM). In this paper, we will discuss the modern medical mechanism of the biological clock disorder resulting in acne from the angle of sex hormones, and analyze the TCM pathogenesis of the disease caused by the disorder of the biological clock.展开更多

It is currently involved in the appearance and worsening of several non-transmissible pathologies, making it an environmental, health, and societal problem. The objective of this work was to evaluate the effects of short-term exposure to air pollution on the level of sex hormones in mechanics. We conducted a cross-sectional, analytical, prospective case-control study in Brazzaville on 228 patients (76 cases and 152 controls) from June 2020 to December 2022, a period of 30 months. This study made it possible to evaluate, on the one hand, the level of sexual hormones in men exposed to automobile pollution according to the automated method (ELFA) on mini vidas and, on the other hand, the quality of the air by a colorimetric, punctual method on a Dräger tube coupled with a Dräger accuro pump. The results obtained made it possible to establish a statistically significant link between automobile pollutants (CO, CO<sub>2</sub>, NO<sub>2</sub>, SO<sub>2</sub>) and the increase in LH and FSH on the one hand and the decrease in testosterone on the other hand. We also noted that the concentrations of automotive pollutants during this study were all above the standards required by the WHO. Exposure to automobile pollutants affects the hypothalamic-pituitary axis and therefore disrupts the level of sex hormones.展开更多

文摘Somatic embryogenesis （SE） is one of the most important steps during regeneration of cotton, but the molecular mechanism of SE remains unclear. SOMATIC EMBRYOGENSIS RECEPTOR KINASE （SERK） gene is known to function in SE. A homolog GhSERK2 （accession number： JF430801） was cloned from Upland cotton and characterized for its functions in SE. GhSERK2 expressed in different tissues and showed higher expression level in floral organs than vegetative ones with the highest levels in ovule and anther. GhSERK2 expressed during SE with a high level at globular embryos stage. Upon treatment with indole-3-butytic acid （IBA）, the transcription level of GhSERK2 was induced and promoted SE subsequently. A 2-day treatment of 2,4-dichlorophenoxyacetic acid （2,4-D） induced the expression of GhSERK2, but treatments of 2,4-D for longer periods sharply inhibited the GhSERK2 transcription level of embryogenic callus （EC）. The levels of hormones, including 3-indoleacetic acid （IAA）, abscisic acid （ABA）, and brassinosteroid （BR）, were increased in the initial calli induced from the over-expression of GhSERK2 cotton. Our results indicated that GhSERK2 expression was associated with induction of SE and closely related to hormone levels during tissue culture in Upland cotton, and the gene might play an important role in regeneration of cotton.

The level of E2 in the female VD patients was lower than the compared group [(34.23±10.99), (44.81±14.65) pg/L, P < 0.05]. ③ The relationship between the score of blood stasis and each indicators: The levels of ET, ET/NO and HCY had significant positive relationship with blood stasis mark (r = 0.352, 0.754, 0.347, P < 0.05-0.01), obvious negative relationship with NO (r =-0.528, P < 0.01) and no clear relationship with female E2/T and male E2/T (r = -0.210, 0.04, P > 0.05). CONCLUSION: ① The levels of ET, HCY and ET/NO are increasing with pathography, while the level of NO is decreasing, which may be the evidence that the possibility of VD pathography may have relationship with the indicators above. ② The level of E2 increase in male's VD patients, and decrease in male's. And the decrease of the female may have relationship with the VD.
文摘Diabetes mellitus is one of the worldwide largest growing metabolic diseases. In this study the effects of consumption of raw garlic on serum lipid level, blood sugar and a number of effective hormones on lipid and sugar metabolism (thyroid hormones and insulin) in individuals either with high level of blood sugar or lipid were investigated. Eighty five volunteers having following clinical history enrolled in the study: Group 1: having blood sugar more than 126 mg/dl (30 vo-lunteers);Group 2: having cholesterol higher than 245 mg/dl (30 volunteers);Group 3: having blood sugar over 126 mg/dl and cholesterol more than 245 mg/dl (25 volunteers). In group 1, there wasn’t a sig-nificant differences between biochemical factors be-fore and after garlic consumption, whereas, in the second group after 6 weeks of garlic consumption a decline in cholesterol (P < 0.001), FBS and TG (P < 0.01) was observed but HDL-C (P < 0.001) was in-creased. Six weeks after termination of garlic con-sumption, cholesterol (P < 0.001), FBS and TG (P < 0.05) were in- creased and HDL-C (P < 0.01) was de-creased. In the third group, total cholesterol (P < 0.001), FBS (P < 0.01) and HbA1c decreased while HDL-C was in- creased. Other factors, including thy-roid hormones (T3, T4), TSH and insulin showed no significant alte- ration. In conclusion our results shown that raw garlic consumption can reduce the FBS and Lipid in hyperglycemic and/or hyperlipidemic individuals.
文摘Objective:To analyze the effect of thyroid-stimulating hormone(TSH)suppression therapy on sex hormone levels in patients undergoing postoperative treatment for thyroid cancer.Methods:A total of 40 patients undergoing postoperative thyroid cancer treatment were selected for data analysis.TSH suppression therapy was implemented during the postoperative period.Patients were grouped according to the TSH level:TSH<0.1,0.1≤TSH<0.5,and TSH≥0.5.Results:Among male patients,there were no significant differences in sex hormone levels at different dosing times and TSH levels(P>0.05).For female patients,testosterone levels at different dosing times showed no significant differences under the same circumstances(P>0.05).The comparison of testosterone levels at different TSH levels over 5 years of TSH suppression therapy did not yield significant differences(P>0.05).However,the comparison of testosterone levels within 5 years of TSH suppression therapy yielded significant differences(P<0.05),with the lowest levels observed at 0.1≤TSH<0.5.Conclusion:The use of TSH suppression therapy in postoperative thyroid cancer treatment minimally affects sex hormone levels in male patients.However,it has a significant impact on female patients.Therefore,preoperative sex hormone testing is recommended,and postoperative monitoring should include regular sex hormone testing.
文摘Acne vulgaris is a common chronic inflammatory disease of pilosebaceous units. And sex hormone level disorder has became a hot research topic in the pathogenesis of acne. Studies show that the biological clock disorder can result in the disorder of sex hormone levels which causes or aggravates acne. Biological clock disorder coincides naturally with "sleep rhythm disorder" in Traditional Chinese Medicine(TCM). In this paper, we will discuss the modern medical mechanism of the biological clock disorder resulting in acne from the angle of sex hormones, and analyze the TCM pathogenesis of the disease caused by the disorder of the biological clock.
文摘Air pollution is today a real concern across the world, responsible for around 7 million deaths per year around the world. It is currently involved in the appearance and worsening of several non-transmissible pathologies, making it an environmental, health, and societal problem. The objective of this work was to evaluate the effects of short-term exposure to air pollution on the level of sex hormones in mechanics. We conducted a cross-sectional, analytical, prospective case-control study in Brazzaville on 228 patients (76 cases and 152 controls) from June 2020 to December 2022, a period of 30 months. This study made it possible to evaluate, on the one hand, the level of sexual hormones in men exposed to automobile pollution according to the automated method (ELFA) on mini vidas and, on the other hand, the quality of the air by a colorimetric, punctual method on a Dräger tube coupled with a Dräger accuro pump. The results obtained made it possible to establish a statistically significant link between automobile pollutants (CO, CO<sub>2</sub>, NO<sub>2</sub>, SO<sub>2</sub>) and the increase in LH and FSH on the one hand and the decrease in testosterone on the other hand. We also noted that the concentrations of automotive pollutants during this study were all above the standards required by the WHO. Exposure to automobile pollutants affects the hypothalamic-pituitary axis and therefore disrupts the level of sex hormones.

文摘The objective of the study was to investigate the effects of dietary energy levels and sources on the blood metabolites,hormone secretion and the composition of follicular fluid in gilts.Fifty-four gilts with initial body weight of(59±4.2) kg were randomly allotted to six treatments.Treatments were low, normal,and high energy feeding levels,which were 87.5%,100%and 112.5%of recommendatory energy requirements by NRC(1998),respectively,and dietary energy sources(starch or fat).Blood samples and follicular fluids were collected on D18 and D19 of the second estrous cycle.The results showed that plasma concentrations of triglycerides and total cholesterol were higher in the fat group than that in the starch group(P【0.05),but those of glucose were similar between the two energy sources(P】0.05);dietary energy level exerted no effect on blood metabolites concentration(P】0.05).Gilts fed the high energy diet had a higher area under curve of plasma insulin(Insulin AUC),insulin-like growth factor-Ⅰ(IGF-Ⅰ) and leptin than did gilts fed the lower energy diet(P【0.05),but there was no significant difference between fat versus starch(P】0.05).Luteinizing hormone(LH) pulses were higher in gilts fed high energy rather than that in low energy diets(P】0.05),plasma concentration of estradiol(E<sub>2</sub>) was higher in the fat group than that in the starch group(P【0.05).The number of large follicles(diameter≥4 mm) and concentrations of IGF-Ⅰand E<sub>2</sub> in follicular fluid were increasing significant as the level of energy increased(P【0.05),but the numbers of large follicles and follicular fluid composition were not affected by the source of dietary energy(P】0.05).The results indicate that gilts fed high energy diets had elevated plasma concentrations of metabolic hormones,IGF-Ⅰand LH secretion,and increased follicular fluid concentrations of IGF-Ⅰ,E<sub>2</sub> and numbers of large follicles;gilts fed the dietary fat had a higher plasma concentration of cholesterol and E<sub>2</sub>.

文摘Specific primers for the MC1R gene of alpacas(GenBank EU1358800) were designed to amplify the cDNA sequence using RT-PCR to seek variation in the sequence and explore the relationship between the expression level of MC1R gene and alpaca coat color.The MC1R gene from white alpaca was cloned successfully and sequence analysis verified that the MC1R gene,encoding 317 amino acids,was 1081 bp in length.Compared with the existing sequence in GenBank,sequence identity was 99.9%and 7 mutations were found.Primers,designed from the sequence obtained,were used to assess the relative expression of MC1R in alpacas of different coat color using QRT-PCR and SPSS 13.0 software.Relative expression of MC1R in the skin of brown alpacas was 4.32 times higher than that in white alpacas after normalization with GAPDH(P【0.01),indicating that MC1R expression may be related to coat color of alpacas.
