ABSTRACT

Nodular goiter has become increasingly prevalent in recent years. Clinically, there has been a burgeoning interest in nodular goiter due to the risk of progression to thyroid cancer. This review aims to provide a comprehensive summary of the mechanisms underlying the therapeutic effect of Chinese medicine (CM) in nodular goiter. Articles were systematically retrieved from databases, including PubMed, Web of Science and China National Knowledge Infrastructure. New evidence showed that CM exhibited multi-pathway and multi-target characteristics in the treatment of nodular goiter, involving hypothalamus-pituitary-thyroid axis, oxidative stress, blood rheology, cell proliferation, apoptosis, and autophagy, especially inhibition of cell proliferation and promotion of cell apoptosis, involving multiple signal pathways and a variety of cytokines. This review provides a scientific basis for the therapeutic use of CM against nodular goiter. Nonetheless, future studies are warranted to identify more regulatory genes and pathways to provide new approaches for the treatment of nodular goiter.

ABSTRACT

Objective:To explore the effects of Shenwei Ningyu pills (SNP), a new Chinese medicine for depression, on the immunoinflammatory response mediated by Toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88) signaling pathway in the hippocampus of rats exposed to chronic restraint stress (CRS). Method:Forty-four male Sprague Dawley rats were randomly enrolled into a normal group, a model group, an escitalopram group, and an SNP group. Except for the rats in the normal group, all rats were exposed to CRS and isolated rearing for 21 days continuously. Rats in the escitalopram group and the SNP group were administered with escitalopram (30 mg·kg<sup>-1</sup>) and SNP (18 mg·kg<sup>-1</sup>) one hour prior to CRS, respectively. The changes in body weight, sucrose preference index, horizontal movement scores, and vertical movement scores were observed by body weight assessment, sucrose preference test, and open field test. The expression of hippocampal TLR4 and MyD88 was detected by Western blot. The content of serum interleukin-1<italic>β</italic> (IL-1<italic>β</italic>), IL-10, and tumor necrosis factor-<italic>α</italic> (TNF-<italic>α</italic>) was detected by enzyme-linked immunosorbent assay (ELISA). Result:The results of the behavioral assessment showed that there was no significant difference in the changes of behavioral baselines among the groups before intervention. However, significant differences were found among the groups following different interventions. The body weight, sugar preference index, horizontal movement score, and vertical movement score of rats in the model group decreased after CRS for 21 days as compared with those in the normal group (<italic>P</italic><0.01). The above indicators in the SNP<italic> </italic>group and the escitalopram group were higher than those in the model group (<italic>P</italic><0.01), which indicated that SNP<italic> </italic>exerted an obvious antidepressant effect. The results of Western blot and ELISA showed that compared with the normal group, the model group showed elevated levels of hippocampal TLR4 and MyD88 and serum IL-1<italic>β</italic> and TNF-<italic>α </italic>(<italic>P</italic>˂0.01) and dwindled serum IL-10 (<italic>P</italic>˂0.01), while SNP<italic> </italic>and escitalopram reversed the conditions in the model group (<italic>P</italic>˂0.01) except for TNF-<italic>α</italic>. Conclusion:The present study indicated that the antidepressant effect of SNP was presumedly achieved by inhibiting the immunoinflammatory response mediated by the TLR4/Myd88 signaling pathway in CRS rats.

ABSTRACT

Objective To study the effects of Chinese medicinal compound Jinmaitong(JMT) on the expressions of nitrotyrosine (NT) and nerve growth factor (NGF) in dorsal root ganglia of diabetic rats. Methods Experimental rat diabetic models were established by the intraperitoneal injection of streptozotocin. Rat models were then randomly divided into four groups including normal control group (Con group),diabetes mellitus group (DM group),Jinmaitong group(JMT group)(treated with JMT similar to the fifteen-fold dose of adult recommended dosage),and taurine group(Tau group)(treated with Taurine similar to the fifteen-fold dose of adult recommended dosage),with 10 rats in each group. The Con and DM groups were treated with distilled water at a daily dose of 1 ml/100 g. All rats were given intragastric administration for 16 weeks and then killed. Body weight and blood glucose were detected before and at the 4th,8th,12th,and 16th week after treatment. The pain threshold to mechanical stimulation with von Frey filament were carried out before death. The expressions of NT and NGF in dorsal root ganglion were detected by immunohistochemistry and Western blot analysis,respectively. Results Immunohistochemistry showed that the average optical density (AOD) of NT expression in DM group were significantly higher than those in control group (P=0.000),and the AOD of NGF was significantly lower than the control group (P=0.006).The AOD of NT(P=0.000,P=0.000) in both treatment groups decreased significantly and the AOD of NGF(P=0.000, P=0.004)significantly increased compared with DM group. The AOD of NT in JMT group was significantly lower than Tau group (P=0.004). Western blot analysis showed that the protein level of NT in DM group was significantly higher than that in control group (P=0.000),and the protein level of NGF was significantly lower than that in control group (P=0.000). Compared with the DM group,the protein level of NT in both treatment groups significantly decreased (P=0.001,P=0.000),and the protein level of NGF increased significantly (P=0.000,P=0.001). Conclusion Traditional Chinese medicine JMT can obviously up-regulate the expressions of NGF and reduce the NT levels in dorsal root ganglia of diabetic rats.

ABSTRACT

OBJECTIVE: To explore an efficient modification strategy for conversion of antibacterial fluoroquinolones to antitumor ones. METHODS: An azole heterocyclic ring, s-triazole, as a bioisotere of the C-3 carboxylic acid for ofloxacin(1), functional acyl-hydrazones and hydrazones, was used as the modified side-chain for the C-3 bioisotere, then the C-3 s-triazole acylhydrazones and s-triazole hydrazone derivatives were designed and their in vitro antitumor activity was evaluated by MTT assay. RESULTS: Fourteen target compounds were synthesized, and they exhibited stronger antitumor activity than the parent ofloxacin. And most importantly, hydrazone derivatives had higher activity than their corresponding acylhydrazone compounds. CONCLUSION: s-Triazole-hydrazone moiety is warranted special attention as an efficient bioisosteric replacement of the C-3 carboxylic acid for further development of antitumor fluoroquinolone lead compounds.

ABSTRACT

To discover novel fluoroquinolone lead compounds as possible anti-infective or/and antitumor chemotherapies, combination principle of pharmacophore-based drug design, a series of novel tricyclic fluoroquinolone title compounds, [1,2,4]triazino[3,4-h][1,8]naphthyridine-8-one-7-carboxylic acid derivatives ( 5a-5p), were designed and synthesized with a fused [1,2,4]-triazine ring unit. Their structures were characterized by spectral data and elemental analysis and the in vitro antibacterial and anti-cell proliferation activities were also evaluated. The results showed that the titled compounds exhibited more significant inhibitory activities against drug-resistant bacteria (Methicillin-resistant Staphylococcus aureus and multi drug-resistant Escherichia coli strains) and three tested cancer cell lines (human hepatoma SMMC-7721, murine leukemia L1210 and human murine leukemia HL60 cells). Interestingly, SAR showed that compounds with electron-donating groups attached to benzene ring had stronger antibacterial activity than antitumor activity, but electron-withdrawing compounds displayed more potential antitumor activity than antibacterial activity, especially antitumor activity of nitro compounds was comparable to comparison doxorubicin. Thus, novel triazine-fused tricyclic fluoroquinolones as potent anti-infective or/and antitumor lead compounds are valuable to pay attention and for further development.

ABSTRACT

To discover novel antitumor rhodanine unsaturated ketones, a series of fluoroquinolone (rhodanine α, β-unsaturated ketone) amine derivatives (5a-5r) were designed and synthesized with fluoroquinolone amide scaffold as a carrier. The structures of eighteen title compounds were characterized by elemental analysis, 1H NMR and MS. The in vitro anti-proliferative activity against Hep-3B, Capan-1 and HL60 cells was evaluated by MTT assay. The results showed that the title compounds not only had more significant anti-proliferative activity against three tested cancer cell lines than that of the parent ciprofloxacin 1, but also exhibited the highest activity against Capan-1 cells. The SAR revealed that some compounds carrying aromatic heterocyclic rings or phenyl attached to an electron-withdrawing carboxyl or sulfonamide substituent were comparable to or better than comparison doxorubicin against Capan-1 cells. As such, it suggests that fluoroquinolone (rhodanine α, β-unsaturated ketone) amines are promising leads for the development of novel antitumor fluoroquinolones or rhodanine analogues.

ABSTRACT

To discover novel antitumor fluoroquinolone lead compounds from a rational modification for antibacterial fluoroquinolones, a fused heterocyclic ketone corresponding to thiazolo[2,3- b][1,2,4]triazolone used as a bioisosteric replacement of the C-3 carboxylic acid group of ciprofloxacin 1, and further modification by a Claisen condensation reaction with substituted benzaldehydes formed novel fluoroquinolone C-3 fuse heterocyclic α, β-unsaturated ketones as the title compounds (6a-6r), separately. The structures of eighteen title compounds were characterized by elemental analysis, 1H NMR and MS, and the in vitro anti-proliferative activity against human hepatoma Hep-3B cells, pancreatic Capan-1 cells and leukemia HL60 cells was evaluated by a MTT assay. The preliminary results showed that the title compounds not only had more significant anti-proliferative activity against three tested cancer cell lines than that of the parent ciprofloxacin 1, but also exhibited the highest activity against Capan-1 cells. In particular, compounds carrying an electron-withdrawing carboxyl (6k, 6m) or sulfonamide substituent (6q, 6r) attached to benzene ring were comparable to or better than constractive drug doxorubicin against Capan-1 cells. As such, it suggests that it is favorable for a fused heterocyclic α, β-unsaturated ketone scaffold instead of the C-3 carboxylic acid group to improve the antitumor activity of fluoroquinolones.

ABSTRACT

To discover an efficient strategy for the conversion of the antibacterial activity of fluoroquinolones into the antitumor activity, the three series of C-3 s-triazole-based derivatives including sulfide ketones (6a-6g), thiosemicarbazones (7a-7g) and fused heterocyclic thiazolotriazoles (8a-8g) were synthesized from ciprofloxacin (1), respectively. The structures were characterized by elemental analysis and spectral data. The antitumor activity was tested against three tumor cell lines (Hep-3B, Capan-1 and HL60) using the MTT assay. The three types of compounds all exhibited stronger anti-proliferative activities than ciprofloxacin in the test. The order of their activities was in compounds 7>8>6, and the order of selectivity against cancer cell lines was Capan-1, Hep-3B and HL60. Meanwhile, the SAR revealed that some compounds with electron-drawing group substituted such as fluoro- and nitro-phenyl compounds (6f, 7f, 8f) and (6g, 7g, 8g) displayed more significant activity than the control compounds, especially the IC50 values of thiosemicarbazone compounds 7f and 7g against Capan-1 was comparable to doxorubicin. Thus, a five-membered triazole as the C-3 bioisostere modified with the functionalized side-chain of sulfide-ketone thiosemicarbazone warrants special attention and further investigation.

ABSTRACT

To explore an efficient strategy for the conversion of antibacterial fluoroquinolones into antitumor fluoroquinolones, an azole heterocyclic ring of oxadiazole instead of the C-3 carboxylic acid group with a functionalized hydrazone group as a modified side-chain, fifteen novel 2-(fluoroquinolon-3-yl)-oxadiazole-5- sulfanylacetylhydrazone derivatives 7a-7o were designed and synthesized on the basis of the pharmacophore hybridization principle from pefloxacin, separately. The structures for fifteen title compounds were characterized by elemental analysis, 1H NMR and MS, and their in vitro antitumor activity against Hep-3B cell line was evaluated by a MTT assay. The results showed that the title compounds exhibited more significantly inhibitory activity than that of the parent pefloxacin, in which compounds with electron-withdrawing group attached on aryl ring had more potency than that of compounds with electron donating group, especially compounds with a carboxylic substituent were comparable to comparison doxorubicin. It suggests that it is favorable for an improvement of antitumor activity to remain a carboxylic acid unit at the aromatic ring.

ABSTRACT

<p><b>OBJECTIVE</b>To observe the inhibition of NK4 protein in the proliferation of human Raji lymphoma xenografts in nude mice, and to explore its molecular mechanism.</p><p><b>METHODS</b>Models of human Raji lymphoma xenograft transfected with HGF gene were established by subcutaneous inoculation in nude mice. After establishment of the models, the mice received continuous NK4 protein via tail vein for 4 weeks, and the weight and tumor growth were monitored every week. After 8 weeks, the expression of HGF mRNA and c-Met mRNA of tumor tissues was measured by real-time fluorescent quantitation PCR. The apoptotic index (AI) and microvessel density (MVD) were evaluated by terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) and immunohistochemistry, respectively.</p><p><b>RESULTS</b>The models of human Raji lymphoma xenograft were successfully established. Although the animal weights of all groups declined, especially in the groups with NK4 protein injection, there was no statistical significance (P > 0.05). The tumor volume in HGF gene transfected group was larger than those of the control groups (P < 0.01), and there was no statistical significance among the control groups (P > 0.05). However, the tumor volume of the NK4 protein injection group decreased significantly (P < 0.01). Expression of HGF mRNA and c-Met mRNA in HGF gene transfected group increased significantly after injection of NK4 protein (P < 0.01). AI in HGF gene transfected group (33.5% ± 12.3%) was significantly lower than that of control groups (89.1% ± 22.3% vs. 81.9% ± 27.0%, P < 0.05), but became significantly higher (119.1% ± 18.9%) after NK4 protein injection (P < 0.01). MVD in HGF gene transfected group (28.5 ± 2.0) was higher than that of control groups (12.2 ± 1.4, 13.8 ± 1.3, P < 0.01), although declined (15.5 ± 2.5) after NK4 protein injection (P < 0.01).</p><p><b>CONCLUSIONS</b>NK4 protein suppresses significantly the growth of human Raji lymphoma xenografts transfected with HGF gene. The pathogenesis may be involved in promoting tumor cell apoptosis and restraining tumor angiogenesis through competitive interrupting HGF/Met signal pathway.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical efficacy of acupuncture combined single photon emission computed tomography (SPECT) in treating coronary heart disease (CHD) and its effect on the myocardial ischemia/perfusion and the recovery of heart functions.</p><p><b>METHODS</b>Totally fifty-nine patients with confirmed CHD were randomly assigned to two groups, the acupuncture group (32 cases) and the nitroglycerine group (27 cases). Patients in the acupuncture group were electro-acupunctured at bilateral Neiguan (PC6) and Xinshu (BL15) for 30 min with the frequency of 2/15 Hz and the current strength 9 - 18 mA after myocardial imaging induced by routine exercises or drug load. 99mTc-MIBI 370 MBq was injected 15 min after needling. The myocardial perfusion imaging was performed immediately after needling. 99mTc-MIBI740 MBq was injected to those in the nitroglycerine group during routine exercises or drug load. The myocardial perfusion imaging was performed 5 min after injection. Patients were asked to sublingual administration of nitroglycerine 1 mg after the myocardial perfusion imaging was completed. 99mTc-MIBI 370 MBq was intravenously injected 5 min later, and myocardial perfusion imaging was performed 5 min after injection.</p><p><b>RESULTS</b>There was statistical difference in changes of radioactive uptake between before and after treatment in the two groups (P < 0.05, P < 0.01). Both acupuncture and buccal administration of nitroglycerine could increase the blood perfusion of ischemic myocardium. But there was no statistical difference in the improvement of ischemic myocardial cells (t = 1.57, P > 0.05).</p><p><b>CONCLUSION</b>Using SPECT could clearly display therapeutic effects of acupuncture on CHD, thus providing a new visible research method for CHD studies.</p>

ABSTRACT

<p><b>OBJECTIVE</b>The study was designed to investigate the impact of non-dilated coronary artery wall lesion on myocardial perfusion.</p><p><b>METHODS</b>Doppler tissue image (DTI) was used to measure regional ventricular wall motion in 43 Kawasaki children with non-dilated coronary arterial wall echocardiographic abnormalities (rough intima and arterial wall thickening) detected by two-dimensional echocardiography (2DE) at acute phase. A total of 31 cases who had both non-dilated coronary lesion and lowered ventricular wall motion velocity at subacute and convalescence phase underwent submaximal exercise single photon emitting computerized tomography (SPECT) for the evaluation of myocardial perfusion.</p><p><b>RESULTS</b>In 43 cases of Kawasaki disease with non-dilated coronary arterial wall abnormalities, 36 cases (83.7%) still had such lesions at subacute phase and 32 (74.4%)at convalescence. At the same time, lowered regional ventricular wall motion (RVWM) was found in 34 cases at subacute phase and in 31 cases at convalescence. DTI and 2DE had a very good correlation in the detection of such abnormalities (chi(c)2 = 9.64, P < 0.01 in subacute period, and chi(c)2 = 7.14, P < 0.01 in convalescence). In 31 cases accepting SPECT, 17 were positive. A total of 22 ischemic regions were detected. Eighteen out of 22 cases having ischemic regions had abnormal RVWM on DTI. SPECT ischemic regions were significantly in accordance with lowered RVWM in ventricular septum and anterior wall (chi(c)2=5.07 and 7.48, P < 0.05 and P < 0.01, respectively) noted in DTI.</p><p><b>CONCLUSION</b>Non-dilated coronary arterial wall abnormality is one of the forms of coronary artery wall lesions which could reduce myocardial flow perfusion. Its clinical significance is worthy of attention.</p>
