Objective: To observe the clin. efficacy and mechanism of penehyclidine hydrochloride in reducing adverse reactions of carboprost tromethamine. Methods: 60 cases of parturients who received carboprost tromethamine injection during cesarean uterine contraction were divided into group A, group B, and group C. Three minutes before intrauterine infusion of carprost tromethamine, group C received i.v. infusion of normal saline, group A received i.v. infusion of penehyclidine hydrochloride 0.5 mg, and group B received i.v. infusion of penehyclidine hydrochloride 1 mg. Result: The incidence of adverse reactions in group A and group B was lower than that in group C, and there was no difference in the incidence of adverse reactions between group A and group B. The levels of motilin and angiotensin in group A and group B were significantly lower than those in group C. Conclusion: Penehyclidine hydrochloride can reduce the clin. adverse reactions of carprost tromethamine. The gastrointestinal adverse reactions may be inhibited by reducing motilin while the cardiovascular adverse reactions may be inhibited by reducing angiotensin II.

Li, Li published the artcileClinical effect of oxytocin combined with prostaglandins on prevention of postpartum hemorrhage of high-risk pregnancy puerpera with caesarean section, Synthetic Route of 58551-69-2, the publication is Xiandai Yaowu Yu Linchuang (2014), 29(6), 619-622, database is CAplus.

The aim of this paper is to investigate the clin. efficacy of oxytocin combined with prostaglandins in the prevention of postpartum hemorrhage of high-risk pregnancy puerpera with caesarean section. High-risk pregnancy puerpera(330 cases) with caesarean section in Affiliated Hospital of Yan’an University from Jan. 2012 to Dec. 2013 were randomly divided into 3 groups(110 cases in each group): carboprost tromethamine+oxytocin(CTO) group, carboprost methylate+oxytocin(CMO) group, and oxytocin group. And patients in the CTO group were i.m. given carboprost tromethamine 250 μg in the body of uterus following fetus expulsion, and then were iv oxytocin 10 U. The patients in the CMO group were sublingual administered with carboprost methylate 1 mg following fetus expulsion, and were iv oxytocin 10 U. The patients in the oxytocin group were iv oxytocin 10 U following fetus expulsion, and were i.m. given oxytocin 10 U in body of uterus. The quantity of bleeding was compared among the three groups during the operation, 2, and 2-4 h after operation. The postpartum hemorrhage, blood transfusion, and addnl. hemostatic measures after delivery were observed among the three groups. The side reaction was also observed among the three groups. During operation, 2, and 2-4 h after operation, the quantity of bleeding of maternal in the CTO group was less than that in the CMO group and oxytocin group, with the significant difference(P<0.05). During the operation, 2 h after operation, the quantity of bleeding of maternal in the CMO group was significantly less than that in the oxytocin group(P<0.05). While 2-4 h after the operation, there was no significant difference. The postpartum hemorrhage, blood transfusion rate, and addnl. intervention measures to stop bleeding in the CTO and CMO groups were significantly lower than those in the oxytocin group(P<0.05). The side effects of the three groups were 9.09%, 8.18%, and 6.36%, resp., and there was no significant difference. CTO is effective in preventing postpartum hemorrhage of high-risk pregnancy. CMO could reach a certain preventive effect, but the application of oxytocin simply showed poor efficacy.

Sinnett-Smith, James published the artcileCharacterization of a bombesin receptor on Swiss mouse 3T3 cells by affinity cross-linking, Quality Control of 70539-42-3, the publication is Journal of Cellular Biochemistry (1988), 38(4), 237-49, database is CAplus and MEDLINE.

A cell surface protein in Swiss 3T3 cells of apparent M_r 75,000-85,000 was identified previously by chem. crosslinking as a major component of the receptor for peptides of the bombesin family in these cells. Because bombesin-like peptides may interact with other cell surface mols., it was important to establish the correlation between receptor binding and functions of this complex and further characterize the M_r 75,000-85,000 cross-linked protein. Detailed time courses carried out at different temperatures demonstrated that the M_r 75,000-85,000 affinity-labeled band was the earliest cross-linked complex detected in Swiss 3T3 cells incubated with ¹²⁵I-labeled gastrin-releasing peptide (¹²⁵I-GRP). Furthermore, the ability of various nonradioactive bombesin agonists and antagonists to block the formation of the M_r 75,000-85,000 cross-linked complex correlated extremely well (r = 0.994) with the relative capacity of these peptides to inhibit ¹²⁵I-GRP specific binding. Pretreatment with unlabeled GRP for up to 6 h caused only a slight decrease in both specific ¹²⁵I-GRP binding and the affinity labeling of the M_r 75,000-85,000 protein. The cross-linked complex is a glycoprotein. First, solubilized affinity labeled M_r 75,000-85,000 complex applied to wheat germ lectin-Sepharose columns was eluted by addition of 0.3M N-acetyl-D-glucosamine. Second, treatment with endo-β-N-acetylglucosaminidase F reduced the apparent mol. weight of the affinity-labeled band from 75,000-85,000 to 43,000, indicating the presence of N-linked oligosaccharide groups.

Myers, Richard A. published the artcileα-Conotoxins, small peptide probes of nicotinic acetylcholine receptors, Application In Synthesis of 70539-42-3, the publication is Biochemistry (1991), 30(38), 9370-7, database is CAplus and MEDLINE.

α-Conotoxins, a family of small peptides from the venoms of the Conus marine molluscs, are selective, snake α-neurotoxin-competitive antagonists of the nicotinic acetylcholine receptor. A new α-conotoxin, SIA, has been purified, sequenced, and synthesized. Crosslinking with bivalent reagents and photoaffinity labeling of the acetylcholine receptor with α-conotoxin yield covalent adducts. Surprisingly, crosslinking to other subunits is considerably more efficient than to the α subunit. The relative efficiency of photoactivatable crosslinking to different subunits of the receptor is a function of placement of the photoactivatable group on the toxin. Since the structures of α-conotoxins can be solved by 2D NMR (Pardi, A. et al., 1989 and Kobayashi, Y. et al., 1989) this family of toxins should provide a set of new ligands for probing the acetylcholine receptor with considerable precision.

Jin, Yuanyuan published the artcileThe combination of C-Myc rearrangement and 1q21 gain is associated with poor prognosis in multiple myeloma, Name: 2-((4-(4-Bromophenylsulfonamido)-1-hydroxynaphthalen-2-yl)thio)acetic acid, the publication is Annals of Hematology (2021), 100(5), 1251-1260, database is CAplus and MEDLINE.

The prognostic value of chromosomal 1q21 gain in newly diagnosed multiple myeloma (NDMM) remains controversial. Add-on Myc aberrations may further worsen the outcome. To investigate whether specific genes located at the 1q21 region, such as myeloid cell leukemia 1 (Mcl-1), are involved in NDMM progression, we examined bone marrow cytogenetic abnormalities in 153 patients with NDMM by fluorescence in situ hybridization. Their response to treatment and survival was also analyzed. C-Myc and Mcl-1 expressions in bone marrow samples were analyzed by RT-PCR. The expression of Mcl-1 was evaluated in bone marrow sections by immunohistochem. MM cell lines were transfected with Mcl-1 siRNA. 1q21 gain was present in 55/153 (35.9%) patients and strongly associated with Myc rearrangement (31/153, 20.3%, P = 0.004). A pos. correlation was observed between Myc and Mcl-1 mRNA levels in bone marrow cells from 47 patients (r = 0.57, P < 0.001). The combination of 1q21 gain and Myc rearrangement was associated with poorer overall survival than Myc rearrangement alone (16.8 vs. 27.9 mo, P = 0.077) or 1q21 gain alone (16.8 vs. 60.7 mo, P < 0.01). High Mcl-1 protein expression in bone marrow plasma cells was associated with Myc rearrangement. Mcl-1 silencing by siRNA inhibited Myc protein expression in three myeloma cell lines. Treatment with the small-mol. Mcl-1 inhibitor, UMI-77, produced similar results. Overall, the combination of Myc rearrangement and 1q21 gain was associated with particularly poor prognosis in patients with MM. Furthermore, our data are consistent with Mcl-1-dependent Myc protein activation.

Peng, Hui published the artcileTherapeutic effect of hemabate on preventing and treating bleeding in cesarean section or post-operation of high-risk parturient women, Application of 2-Amino-2-(hydroxymethyl)propane-1,3-diol (Z)-7-((1R,2R,3R,5S)-3,5-dihydroxy-2-((S,E)-3-hydroxy-3-methyloct-1-en-1-yl)cyclopentyl)hept-5-enoic acid, the publication is Yixue Linchuang Yanjiu (2009), 26(7), 1335-1336, database is CAplus.

The aim of this paper is to investigate therapeutic effect of hemabate on preventing and treating bleeding in cesarean section or post-operation of high-risk parturient women, and its safety. 60 High-risk parturient women were divided into two groups: hemabate group (A group with 30 cases)and oxytocin+methyl carboprost suppository group (B group with 30 cases). The bleeding amount was recorded during operation and 24h post- operation. Bleeding incidence rate in group B was significantly higher than that in group A (16.7 vs 6.67%). The bleeding amounts during operation and 24h post-operation were 441.57±252.03 mL and 651.26±308.24 mL in B group, while those in group A were 317.31±162.47 mL and 512.26±251.54 mL, resp., with significant difference between the two groups (P<0.05). Hemabate can effectively reduce bleeding amount in cesarean section or post-operation of high-risk parturient women and has advantages of safety, high performance, quickness and convenience.

Ma, Xiuguang published the artcileThe Drosophila morphogenetic protein Bicoid binds DNA cooperatively, Formula: C18H20N2O12, the publication is Development (Cambridge, United Kingdom) (1996), 122(4), 1195-206, database is CAplus and MEDLINE.

The Drosophila morphogenetic protein Bicoid, encoded by the maternal gene bicoid, is required for the development of the anterior structures in the embryo. Bicoid, a transcriptional activator containing a homeodomain, is distributed in an anterior-to-posterior gradient in the embryo. In response to this gradient, the zygotic gene hunchback is expressed uniformly in the anterior half of the embryo in a nearly all-or-none manner. In this report we demonstrate that a recombinant Bicoid protein binds cooperatively to its sites within a hunchback enhancer element. A less than 4-fold increase in Bicoid concentration is sufficient to achieve an unbound/bound transition in DNA binding. Using various biochem. and genetic methods we further demonstrate that Bicoid mols. can interact with each other. Our results are consistent with previous studies performed in the embryo, and they suggest that one mechanism to achieve a sharp on/off switch of gene expression in response to a morphogenetic gradient is cooperative DNA binding facilitated by protein-protein interaction.

Ling, Zhang published the artcileEffect of carboprost tromethamine in prevention of postpartum hemorrhage in cesarean section., Recommanded Product: 2-Amino-2-(hydroxymethyl)propane-1,3-diol (Z)-7-((1R,2R,3R,5S)-3,5-dihydroxy-2-((S,E)-3-hydroxy-3-methyloct-1-en-1-yl)cyclopentyl)hept-5-enoic acid, the publication is Pakistan journal of pharmaceutical sciences (2018), 31(5(Special)), 2257-2262, database is MEDLINE.

Carboprost tromethamine is a synthetic prostaglandin derivative, which can effectively promote law contraction of the uterus and significantly reduce the amount of bleeding during and after delivery. In this study, we explored the effect of carboprost tromethamine on the prevention of postpartum hemorrhage after cesarean section and the effect on coagulation function and hemodynamics. At the same time, the effects of oxytocin and carboprost tromethamine were studied in different groups. The results showed that the amount of 2h bleeding (256.7±65.21) mL and the amount of 24h hemorrhage (308.3±78.3) after the operation were significantly decreased, and the difference was statistically significant (P<0.05). After the operation, the levels of APTT, TT and Fib in the two groups were significantly lower than those before the operation. The levels of SBP (119.4±8.24) mmHg and DBP (79.6±6.21) mmHg in the experimental group were significantly higher than those of the control group. In summary, carboprost tromethamine has a significant effect on the prevention of postpartum hemorrhage in cesarean section, and has a significant effect on improving the state of hypercoagulable blood and maintaining the stable hemodynamic state, which has clinical a value.

Objective: To investigate the effect of the combination of Ergometrine and Carboprost Tromethamine Injection in preventing postpartum hemorrhage in patients with scarred uterus re-cesarean section and its influence on glutathione peroxidase (GSH-px), superoxide dismutase (SOD), malondialdehyde (MDA) and postpartum lactation. Methods: A total of 92 patients with scarred uterus re-cesarean section in our hospital from Feb. 2018 to Apr. 2020 were selected as the research objects. They were divided into observation group and control group by simple randomization method, with 46 cases in each group. The control group was treated with Carboprost Tromethamine Injection to prevent postpartum hemorrhage, and the observation group was treated with Ergometrine combined with Carboprost Tromethamine Injection to prevent postpartum hemorrhage. The efficacy, postpartum hemorrhage, recovery, lactation, and adverse reactions, coagulation function indexes [activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen (FIB), D-dimer (DD)], serum GSH-px, SOD, MDA levels before and 24 h after the operation of the two groups were compared. Results: After treatment, the total effective rate of the observation group was 93.48% higher than that of the control group 76.09% (P<0.05). The bleeding volume and rate of postpartum hemorrhage at 2 h and 24 h in the observation group were lower than those in the control group, the duration of lochia and hospital stay were shorter than those in the control group, and the uterine fundus declined faster than the control group (P<0.05). The levels of APTT, PT, FIB, DD, and serum MDA in the two groups aT24 h after surgery were lower than those before the operation, and the observation group was lower than the control group, and the serum GSH-px and SOD levels were higher than those before operation, and the observation group was higher than the control group (P<0.05). The lactation initiation time of the observation group was shorter than that of the control group, and the lactation volume scores of the 1 and 2 d postpartum were higher than those of the control group (P<0.05); there was no significant difference in the incidence of adverse reactions between the two groups (P>0.05). Conclusion: The combined application of Ergometrine and Carboprost Tromethamine Injection to prevent postpartum hemorrhage in patients with scarred uterus re-cesarean section can significantly improve the preventive effect, reduce postpartum hemorrhage, and promote the recovery of patients, improve coagulation function and lactation, reduce serum GSH-px, SOD, MDA levels, reduce oxidative stress, and have good safety.
