Its dis-regulation in the kidney leads to or is associated with certain renal diseases or disorders, most notably the urinary concentration defect. Hypertonicity, which the kidney medulla is normally exposed to,activates NFAT5 through phosphorylation of a signaling molecule or NFAT5 itself. Hypotonicity inhibits NFAT5 through a similar mechanism. More than a dozen of protein and lipid kinases have been identified to contribute to tonicity-dependent regulation of NFAT5. Hypertonicity activates NFAT5 by increasing its nuclear localization and transactivating activity in the early phase and protein abundance in the late phase. The known mechanism for inhibition of NFAT5 by hypotonicity is a decrease of nuclear NFAT5. The present article reviews the effect of each kinase on NFAT5 nuclear localization, transactivation and protein abundance, and the relationship among these kinases, if known. Cyclosporine A and tacrolimus suppress immune reactions by inhibiting the phosphatase calcineurin-dependent activation of NFAT1. It is hoped that this review would stimulate the interest to seek explanations from the NFAT5 regulatory pathways for certain clinical presentations and to explore novel therapeutic approaches based on the pathways. On the basic science front, this review raises two interesting questions. The first one is how these kinases can specifcally signal to NFAT5 in the context of hypertonicity or hypotonicity, because they also regulate other cellular activities and even opposite activities in some cases. The second one is why these many kinases, some of which might have redundant functions, are needed to regulate NFAT5 activity. This review reiterates the concept of signaling through cooperation. Cells need these kinases working in a coordinated way to provide the signaling specificity that is lacking in the individual one. Redundancy in regulation of NFAT5 is a critical strategy for cells to maintain robustness against hypertonic or hypotonic stress.展开更多

In this paper, a new monotonic constraint model is proposed to represent a type of common domain knowledge. And then, the monotonic constraint estimation algorithm is proposed to learn the parameters with the monotonic constraint model. In order to demonstrate the superiority of the proposed algorithm, series of experiments are carried out. The experiment results show that the proposed algorithm is able to obtain more accurate parameters compared to some existing algorithms while the complexity is not the highest.展开更多

Control mice received vehicle(phosphate-buffered saline). All mice were killed 2mo after injections, and the extent of cell death and the protein expression levels of Ton EBP and aldose reductase(AR) were examined.RESULTS: The Ton EBP and AR protein levels and the death of RGC were significantly increased in the retinas of diabetic mice compared with controls 2mo after the induction of diabetes. Terminal deoxynucleotidyl transferase(Td T)-mediated d UTP nick end labeling(TUNEL)-positive signals co-localized with Ton EBP immunoreactive RGC. These changes were increased in the diabetic retinas compared with controls.CONCLUSION: The present data show that AR and Ton EBP are upregulated in the DR and Ton EBP may contribute to apoptosis of RGC in the DR.展开更多

The experimental rats were divided into 4 groups. With exception of group D in which the rats were only administered with DENA, the rats in the groups A, B, C were previously, simultaneously and subsequently fed with A L tonic capsule respectively while they were administered with DENA. The DNA content of all rat livers was measured using automatic image analysis technique 20 weeks after administration of DENA. The results showed that the highest and lowest DNA contents were respectively seen in the groups D and A. There was significant difference in DNA contents between the groups A or B or C and D, and also between the groups A and B or C (both P <0.01). 4 components (4C) and ≥5C cells were predominant in the group D, while 2C cells were the minority. The number of 2C cells in the groups A, B, C was significantly higher than that in the group D, and the number of ≥5C cells in the groups A, B, C was markedly lower than that in the group D ( P <0.01). Also, there was very significant difference in the number of 2C and ≥5C cells between group A and B or C ( P <0.01). It was concluded that A L tonic capsule could effectively inhibit the increase of DNA content of hepatocytes and improve the distribution of DNA content in rat hepatocarcinogenesis, especially in group A.展开更多

Methods: The related case reports published in periodicals published from 1949 to 2006 were analyzed with the bibliometrics method. Possibility on safety assessment of Chinese materia medica was discussed as well with the method of link analysis. Results: The total number of the tonics selected for the present study was 101, including 44 single drugs and 46 set prescriptions with adverse drug reactions (ADR) found in these tonics. It was found that ADR of 10 single drugs and 29 preparations were not specified in authoritative Chinese materia medica monographs. Among all the set prescriptions, the problem of injection has been standing on the top. Statistical analysis on single factor demonstrates that the most frequently referred ADR come from drug abuse (accounting for 29.20%), and overdose (24.54%). Conclusion: The safety problem of injection remains in a trend of robust growth at least for a period of time, thus reappraisal of the safety issue for the tonics of injection is imperative. It is essential for the public to take doctor’s advice to guarantee safe administration of the tonics, especially for the patients with allergic constitution or those suffering from the liver and heart diseases.展开更多

Understanding the protection mechanism against excessive airway narrowing and how it breaks down is fundamental to solving the problem of asthma. In this paper we have proposed a stochastic modeling the airway smooth muscle bundle for reproducing AHR such as an increased sensitivity of the airways to an inhaled constrictor agonist, a steeper slope of the dose-response curve, and a greater maximal response to agonist. A large number N of contractile muscle cells was assumed to repeat themselves in between contraction and relaxation asynchronously. Dynamic equilibrium of statistic physics was applied to the system of ASM bundle. Thus, the relation of dose to response of a piece of ASM bundle was described by Φ=tanh(βH) , where β was Boltzman factor and H represented energy of contraction induced by constrictor agents. Each of adjacent pair contractile cells was assumed to have Ising-type of antimagnetic interactions of preference energy J (for the condition of contraction-relaxation) between them. A motion equation for a piece of ASM bundle was described by Φ=N(H-zJΦ , which explained existence of combined tonic and phasic contractions. Based on observations of Venegas et al. [4], airway responsiveness was assumed to be assessable by total volume of the ventilation defects (TVD) of 13NN PET-CT images. Interactions via propagation of Ca ion waves between ASM bundles would cause percolation probability by PΦ=(1+tanh(βH))2/4 along the tree, then the relation of dose βH to TVD was described by TVD=PΦ[1-(1-PΦ)3/PΦ3]-TVD0. TVD0 represented the protection mechanism against excessive airway narrowing, which was determined by the ratio of amplitudes between tonic and phasic contractions, thus the balance of amplitudes between tonic and phasic contractions of peripheral lobular smooth muscles would be the determinant of AHR.展开更多

Goal: The objective was to assess immediate maternal and neonatal outcomes in women who reported having used the traditional pharmacopoeia for utero-tonic purposes. Methodology: We conducted a multi-centric cross- sectional study with prospective data collection in the maternities of the Laquintinie Hospital, Bonassama District and Nylon Hospitals. It took place over a period of seven months, from 1st October 2016 to 31st April 2017. This included all women who reported having used the unconventional pharmacopoeia for utero-tonic purposes before or after contractions started. The student and Chi-square tests were interpreted at the statistical threshold of 5% and the 95% confidence intervals. Results: We recruited 168 cases, 68.5% of the 245 women interviewed. The mean age was 27.1 ± 0.41 years;55% of our respondents had a secondary level of education;80% of them were admitted at term and 43% were multiparous. Nulliparity predisposed to traditional pharmacopoeia use (RR = 1.55, CI = 0.79 - 3.03) but primiparity reduced this risk (RR = 0.4, CI = 0.24 - 0.926). Stimulation of labor was the first indication in 85% of women, the rectal evacuation enema was the main route used (67%). The majority of plants used were those of the families Asteraceae, Anthericaceae, and Malvaceae. In per partum, 42% had a brilliant dilatation;there was a statistically significant association between the occurrence of dynamic dystocia (CI = 0.28 - 1.54, p = 0.006) and the risk of perineal tear (RR = 3.13, CI = 1.68 - 5.85;p = 0.007). The APGAR score at 5 min of life was less than 7 in 64% of cases (p = 0.027). The caesarean section rate was 69%. Conclusion: Traditional products with uterotonic effects are frequently used and unregulated with its corollary of materno-fetal complications.展开更多

文摘NFAT5 plays a critical role in maintaining the renal functions. Its dis-regulation in the kidney leads to or is associated with certain renal diseases or disorders, most notably the urinary concentration defect. Hypertonicity, which the kidney medulla is normally exposed to,activates NFAT5 through phosphorylation of a signaling molecule or NFAT5 itself. Hypotonicity inhibits NFAT5 through a similar mechanism. More than a dozen of protein and lipid kinases have been identified to contribute to tonicity-dependent regulation of NFAT5. Hypertonicity activates NFAT5 by increasing its nuclear localization and transactivating activity in the early phase and protein abundance in the late phase. The known mechanism for inhibition of NFAT5 by hypotonicity is a decrease of nuclear NFAT5. The present article reviews the effect of each kinase on NFAT5 nuclear localization, transactivation and protein abundance, and the relationship among these kinases, if known. Cyclosporine A and tacrolimus suppress immune reactions by inhibiting the phosphatase calcineurin-dependent activation of NFAT1. It is hoped that this review would stimulate the interest to seek explanations from the NFAT5 regulatory pathways for certain clinical presentations and to explore novel therapeutic approaches based on the pathways. On the basic science front, this review raises two interesting questions. The first one is how these kinases can specifcally signal to NFAT5 in the context of hypertonicity or hypotonicity, because they also regulate other cellular activities and even opposite activities in some cases. The second one is why these many kinases, some of which might have redundant functions, are needed to regulate NFAT5 activity. This review reiterates the concept of signaling through cooperation. Cells need these kinases working in a coordinated way to provide the signaling specificity that is lacking in the individual one. Redundancy in regulation of NFAT5 is a critical strategy for cells to maintain robustness against hypertonic or hypotonic stress.

文摘The detrital modes of the sandstones from the south basin of Dabie（大别） orogenic belt during the Early-Middle Jurassic are complex due to multiple supplying.Detrital compositions of medium-coarse sandstones from the Lower-Middle Jurassic,Huangshi（黄石）,show three main provenances：recycled ororgen,volcanic arc（arc orogen）,and continental block on the bases of the Dickinson discriminating diagrams of modal composition and analysis of sandstone petrofacies.Combined with sparse published paleocurrent data,geotectonic setting of the study area,and the unpublished detrital zircon age data,the positions of the main provenances are inferred as follows：coastal orogenic belt（COB） in the East China provided detritus as the recycled orogen provenance;Dabie orogenic belt（DOB） to the north was the source of volcanic arc（arc orogen） materials;and the continental block clasts were likely from the uplift of the Yangtze basement（UYB）（Jiangnan（江南） uplift）.Six sedimentary cycles are recognized in the studied section,one in Wuchang（武昌） Formation,and five in Huajiahu（花家湖） Formation.During the deposition,the three main provenances play different roles.The quantitative petrofacies analysis revealed distinct changes of the effect from each source,that is,61.9%（Cycle Ⅰ）→54.5%（Cycle Ⅲ）→50%（Cycle Ⅳ）→57.9%（Cycle Ⅴ）→14.3%（Cycle Ⅵ）,14.3%（Cycle Ⅰ）→21.2%（ Cycle Ⅲ）→40%（Cycle Ⅳ）→36.8%（Cycle Ⅴ）→14.3%（Cycle Ⅵ）,and 23.8%（Cycle Ⅰ）→24.2%（Cycle Ⅲ）→10%（Cycle Ⅳ）→5.3%（Cycle Ⅴ）→71.4%（Cycle Ⅵ） from COB,DOB,and UYB,respectively.The results show that（1） COB behaved in considerable activation during the EarlyJurassic but weakened in the Middle Jurassic;（2） the vigorous tectonic uplift of DOB initiated in Middle Jurassic;and（3） UYB was in stabilization basically from the Early to Middle Jurassic.

文摘The effects of A L tonic capsule on DNA content in rat experimental hepatocarcinogenesis induced by diethylnitrosamine (DENA) were observed. The experimental rats were divided into 4 groups. With exception of group D in which the rats were only administered with DENA, the rats in the groups A, B, C were previously, simultaneously and subsequently fed with A L tonic capsule respectively while they were administered with DENA. The DNA content of all rat livers was measured using automatic image analysis technique 20 weeks after administration of DENA. The results showed that the highest and lowest DNA contents were respectively seen in the groups D and A. There was significant difference in DNA contents between the groups A or B or C and D, and also between the groups A and B or C (both P <0.01). 4 components (4C) and ≥5C cells were predominant in the group D, while 2C cells were the minority. The number of 2C cells in the groups A, B, C was significantly higher than that in the group D, and the number of ≥5C cells in the groups A, B, C was markedly lower than that in the group D ( P <0.01). Also, there was very significant difference in the number of 2C and ≥5C cells between group A and B or C ( P <0.01). It was concluded that A L tonic capsule could effectively inhibit the increase of DNA content of hepatocytes and improve the distribution of DNA content in rat hepatocarcinogenesis, especially in group A.

Understanding the protection mechanism against excessive airway narrowing and how it breaks down is fundamental to solving the problem of asthma. In this paper we have proposed a stochastic modeling the airway smooth muscle bundle for reproducing AHR such as an increased sensitivity of the airways to an inhaled constrictor agonist, a steeper slope of the dose-response curve, and a greater maximal response to agonist. A large number N of contractile muscle cells was assumed to repeat themselves in between contraction and relaxation asynchronously. Dynamic equilibrium of statistic physics was applied to the system of ASM bundle. Thus, the relation of dose to response of a piece of ASM bundle was described by Φ=tanh(βH) , where β was Boltzman factor and H represented energy of contraction induced by constrictor agents. Each of adjacent pair contractile cells was assumed to have Ising-type of antimagnetic interactions of preference energy J (for the condition of contraction-relaxation) between them. A motion equation for a piece of ASM bundle was described by Φ=N(H-zJΦ , which explained existence of combined tonic and phasic contractions. Based on observations of Venegas et al. [4], airway responsiveness was assumed to be assessable by total volume of the ventilation defects (TVD) of 13NN PET-CT images. Interactions via propagation of Ca ion waves between ASM bundles would cause percolation probability by PΦ=(1+tanh(βH))2/4 along the tree, then the relation of dose βH to TVD was described by TVD=PΦ[1-(1-PΦ)3/PΦ3]-TVD0. TVD0 represented the protection mechanism against excessive airway narrowing, which was determined by the ratio of amplitudes between tonic and phasic contractions, thus the balance of amplitudes between tonic and phasic contractions of peripheral lobular smooth muscles would be the determinant of AHR.

Medical specialists think that hair loss is caused by: 1.overwork, insufficient sleep, low spirits or malnutrition thathinder the blood circulation and hurt the hair; 2. over secretionof male hormones, reducing ATP; and 3. irregular metabolism,
文摘The Chinese soft-shell turtle is regarded as a traditional Chinese corroborant and valuable Chinese medicine. It is of high nutrition, containing many elements necessary for health such as polypeptide, holoside, amino-acid and vitamin A, D, E and other trace elements. When they are extracted through the traditionalprocessing method under high temperature, all these elements are easily dissolved and broken down, losing their biological activation.
文摘Introduction: The use of traditional preparations for the induction or acceleration of labor remains a common practice in our country in particular and in Africa in general with sometimes derogatory outcomes for the mother and the fetus. Goal: The objective was to assess immediate maternal and neonatal outcomes in women who reported having used the traditional pharmacopoeia for utero-tonic purposes. Methodology: We conducted a multi-centric cross- sectional study with prospective data collection in the maternities of the Laquintinie Hospital, Bonassama District and Nylon Hospitals. It took place over a period of seven months, from 1st October 2016 to 31st April 2017. This included all women who reported having used the unconventional pharmacopoeia for utero-tonic purposes before or after contractions started. The student and Chi-square tests were interpreted at the statistical threshold of 5% and the 95% confidence intervals. Results: We recruited 168 cases, 68.5% of the 245 women interviewed. The mean age was 27.1 ± 0.41 years;55% of our respondents had a secondary level of education;80% of them were admitted at term and 43% were multiparous. Nulliparity predisposed to traditional pharmacopoeia use (RR = 1.55, CI = 0.79 - 3.03) but primiparity reduced this risk (RR = 0.4, CI = 0.24 - 0.926). Stimulation of labor was the first indication in 85% of women, the rectal evacuation enema was the main route used (67%). The majority of plants used were those of the families Asteraceae, Anthericaceae, and Malvaceae. In per partum, 42% had a brilliant dilatation;there was a statistically significant association between the occurrence of dynamic dystocia (CI = 0.28 - 1.54, p = 0.006) and the risk of perineal tear (RR = 3.13, CI = 1.68 - 5.85;p = 0.007). The APGAR score at 5 min of life was less than 7 in 64% of cases (p = 0.027). The caesarean section rate was 69%. Conclusion: Traditional products with uterotonic effects are frequently used and unregulated with its corollary of materno-fetal complications.
文摘In Zhangbaling Tectonic Belt,two types of mineralization,auriferous quartz veins and alter- ation halos,can observed within many deposits.The pressure of metallogenesis of auriferous al- teration halos ismuch higher than thatof quartz vein,thetemperatures ofmetallogeneses ofthese two types of orebodies are don’tthe same Geochemistry study indicates thatboth ofthem are mi- cro- mesothermal deposits related to Yanshanian granites.The results of proton microprobe analy- sis of sulphides from the gold deposits in the area show that the“invisible” gold existed in sul- phides is in the form ofmicro inclusions,and the concentration of“invisible” gold in sulphidemin- erals within quartz vein is poorerthan thatfrom alteration halos.Field observation shows thatthe structural modality of the fractures controlling the orebodies of auriferous quartz vein is different from thatof the auriferous alteration zones.The fracture controlling the orebodies of auriferous alteration halos is compress- shearfracture,auriferous quartzvein is controlled by extensive fault. The alteration halos crosscut by auriferous quartz vein.The wallrocks of the former altered strongly and developed alteration zones well.The wallrocks of auriferous quartz vein altered slightly.The results of tectonogeochemical study shows that the concentration of associated met- allogenesis elements and intensity of alteration are positively correlated with tectonic deformation strength for auriferous alteration halos.Itindicates that it is probably a general character for mi- cro- mesothermal gold deposits due to the multistages of metallogeneses took place.The tectonic environmentis the most important fact determining the mechanism of fluid flow and precipitationof gold,and then the types of mineralization and modes of gold.
