Metal ion metabolism： New ideas for the traditional Chinese medicine prevention and treatment of chronic liver disease / 临床肝胆病杂志

Chronic liver disease （CLD） tends to have a high incidence rate and impose a serious burden on society and families. Studies have shown that metal ion metabolism is closely associated with CLD， and some Chinese herbal medicines can play a role in the prevention and treatment of CLD by regulating metal ion metabolism. At present， the synthetic drugs currently used for the treatment of CLD fail to achieve a satisfactory effect， and therefore， a variety of Chinese herbal medicines are being used as supplementary and alternative therapies for CLD. This article introduces the role of metal ion metabolism in CLD and the regulatory effect of Chinese herbal medicines and their active components on CLD， and the analysis shows that metal ion metabolism is expected to provide new ideas for the research on CLD and a theoretical basis for the clinical treatment of CLD. For the role of metal ion metabolism in the treatment of CLD， more prospective clinical study data are needed in the future to provide effective and safe treatment regimens for patients with CLD.

ObjectiveTo discuss the effect of modified Gegen Qinliantang （MGQT） on blood glucose and lipids and Takeda G protein-coupled receptor 5 （TGR5）-related pathways in pancreatic tissue of obese type 2 diabetes mellitus （T2DM） mice. MethodA total of 10 male specific pathogen free （SPF） m/m mice （7 weeks old） and 50 male SPF （7 weeks old） were adaptively fed for one week in SPF laboratory. The m/m mice were included in the blank group. T2DM was induce d in the 50 db/db mice. The model mice were randomized into the model group， metformin group （0.2 g·kg-1）， high-dose， medium-dose， and low-dose （31.9， 19.1， 6.4 g·kg-1） MGQT groups， with 10 in each group， and the drug dose was10 mL·kg-1. The model group and the blank group received distilled water of the same volume. The administration lasted 12 weeks （once/day）. Fasting blood glucose （FBG） was detected regularly. After 12 weeks of administration， serum levels of glycated serum protein （GSP）， serum glucose （GLU）， total cholesterol （TC）， triglycerides （TG）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C） were detected. Pathological changes in the pancreatic tissue were based on hematoxylin-eosin （HE） staining. Western blot was used to determine the protein expression of TGR5， protein kinase A （PKA）， phosphorylated （p）-PKA， cyclic-AMP response element binding protein （CREB）， p-CREB， proprotein convertase 1/3 （PC1/3）， and glucagon-like peptide-1 （GLP-1） in pancreatic tissues. The level of cyclic adenosine monophosphate （cAMP） in pancreatic tissue was determined by enzyme-linked immunosorbent assay （ELISA）. ResultCompared with the blank group， the model group had pathological changes in pancreatic tissue， high levels of FBG， GSP， GLU， TC， TG， and LDL-C （P<0.01）， low level of HDL-C （P<0.05）， low protein expression of TGR5， p-PKA （Thr197）/PKA， p-CREB （Ser133）/CREB， PC1/3， and GLP-1 in pancreatic tissue （P<0.01）， and low content of cAMP in the pancreas （P<0.01）. Pancreatic tissue lesion in the treatment groups were milder than that in the model group. Both the high-dose MGQT and metformin can reduce the levels of FBG， GSP， GLU， TC， TG， and LDL-C in db/db mice （P<0.05， P<0.01） and increase the level of HDL-C （P<0.01）. Except the GLP-1 protein in the medium-dose MGQT group， the protein expression of TGR5， p-PKA （Thr197）/PKA， p-CREB （Ser133）/CREB， PC1/3， and GLP-1 in the high-dose and medium-dose MGQT groups and the metformin group increased compared with that in the model group （P<0.05， P<0.01）. The content of cAMP in the pancreatic tissue of the high-dose and medium-dose MGQT groups and the metformin group was raised compared with that in model group （P<0.05， P<0.01）. ConclusionMGQT can improve the glucose homeostasis in db/db mice with T2DM by regulating TGR5/cAMP/GLP-1 signaling pathway-related protein expression.

Effect of hydroxysafflor yellow A on depressive-like behavior and expression of GABAAR protein in hippocampus of chronic restraint stress model mice / 中华行为医学与脑科学杂志

Objective:To investigate the effects of hydroxysafflor yellow A (HSYA) on depressive-like behavior and expression of type A γ-aminobutyric acid receptor(GABAAR)in hippocampus of chronic restraint stress model mice.Methods:The SPF grade male C57BL/6C mice were divided into Control group, HSYA group, Model group, Model + HSYA group and Model + fluoxetine group according to random number table method, with 12 mice in each group.Mice model of depression was established by chronic restraint stress.Mice in HSYA group and Model+ HSYA group were intraperitoneally injected with HSYA(20 mg/kg), mice in Model+ fluoxetine group were injected intraperitoneally with fluoxetine (10 mg/kg), and mice in Control group and Model group administered with 0.9% sodium chloride solution intraperitoneally once a day for 14 days.Then, the forced swimming test (FST) and tail suspension test (TST) were performed to evaluate the depressive-like behavior of mice, and the protein expression levels of different subtypes of GABAAR in the hippocampus of mice were determined by Western blot.SPSS 19.0 and GraphPad Prism 8.0 software were used for data statistical analysis and mapping.One-way ANOVA was used for comparison among groups, and Tukey-HSD test was used for further pairwise comparison.Results:(1) In the behavioral tests, there were significant differences in swimming immobility time of FST and tail suspension immobility time of TST among the five groups ( F=21.59, 20.81, both P<0.05). The swimming immobility time ((143.91±9.97) s) and tail suspension immobility time (( 107.00±6.54) s) in Model group were higher than those in Control group ((52.92±6.70) s, ( 43.50±5.96) s, both P<0.05). There were no significant difference in swimming immobility time and tail suspension immobility time between Model+ HSYA group ((26.17±7.69)s, ( 20.17±7.89)s) and Model+ fluoxetine group ((61.60±16.22)s, (34.14±10.74)s)(both P>0.05), but the swimming immobility time and tail suspension immobility time in these two groups were lower than those in Model group (both P<0.05). (2) The Western blot results showed that there were significant differences in the expression of GABAARβ1 and GABAARβ2 protein in hippocampus among the four groups ( F=12.21, 11.40, both P<0.05). The expression levels of GABAARβ1(45.60±10.76) and GABAARβ2 (46.27±4.82) protein in hippocampus of Model group were lower than those in Control group ((100.00±3.44), (100.00±3.26), both P<0.05). Compared to Model group, the expression of GABAARβ1 (79.91±5.00) and GABAARβ2 (79.08±5.53) protein in hippocampus of Model+ HSYA group were higher (both P<0.05). In addition, the expression of GABAARα1 and GABAARγ1 proteins in hippocampus were not significantly different among the four groups( F=0.23, 0.10, both P>0.05). Conclusion:HSYA can effectively alleviate depressive-like behavior in depression model mice, which may be related with the upregulation of GABAARβ1 and GABAARβ2 of hippocampus tissue.

Transcranial magnetic stimulation can enhance the effectiveness of motor imagery therapy after a stroke / 中华物理医学与康复杂志

Objective:To observe any effect of combining motor imagery therapy (MIT) with repeated transcranial magnetic stimulation (rTMS) for improving upper limb motor functioning after a stroke.Methods:Ninety stroke survivors were randomly divided into a control group, an MIT group and a combination group, each of 30. All received conventional rehabilitation therapy, while the MIT group additionally received MIT and the combination group received the MIT along with 1Hz rTMS applied over the M1 region of the contralateral cortex. Before and after 4 weeks of treatment, everyone′s upper limb functioning was quantified using the Fugl-Meyer assessment scale (FMA) and the Hong Kong version of the hemiplegia upper limb function test (FTHUE-HK). Motor evoked potentials (MEPs), cortical latency (CL) and central motor conduction time (CMCT) were also recorded.Results:After the treatment the average FMA and FTHUE-HK scores of all three groups had improved significantly. The average CL and CMCT were significantly shortened. Compared with the control group, the average upper limb FMA score and FTHUE-HK scores of the treatment group were significantly higher. The combination group showed a significant improvement in its average MEP cortical latency and CMCT values.Conclusions:MIT therapy alone can improve the upper limb motor functioning of stroke survivors, but it is more effective in combination with rTMS.

Rapid identification of pufferfish in roast fish fillet by real-time PCR.

The purpose of this study was to develop a rapid method based on a real-time PCR assay designed to identify the presence of pufferfish in roasted fish fillet. Specific primers and probes were designed targeting Takifugu spp. and Lagocephalus spp., the most common genera in China. Specificity and sensitivity of this assay design were tested by using artificially spikes of pufferfish mixed in with other fish, such as Gadus and Thamnaconus septentrionalis,among others. Fifteen samples of retail roasted fish fillet and six samples from a 1999 poisoning event that occurred in Fujian province China were analysed for pufferfish. When the assay design was validated, no cross-reaction was observed between pufferfish and other species of fish. The limit of detection (LOD) was determined to be 0.001 ng pufferfish template, and the sensitivity of the method was 1%. Lagocephalus lunari was detected in six samples assayed from 1999 and no pufferfish was detected in the 15 retail roasted fish fillet samples tested. These results showed that the method was efficient for screening for pufferfish contamination in the roasted fish fillet and it could benefit public health protection by reducing the risk of tetrodotoxin poisoning.

Prohibitin regulates mTOR pathway via interaction with FKBP8 / 医学前沿

The ability of tumor cells to sustain continuous proliferation is one of the major characteristics of cancer. The activation of oncogenes and the mutation or inactivation of tumor suppressor genes ensure the rapid proliferation of tumor cells. The PI3K-Akt-mTOR axis is one of the most frequently modified signaling pathways whose activation sustains cancer growth. Unsurprisingly, it is also one of the most commonly attempted targets for cancer therapy. FK506 binding protein 8 (FKBP8) is an intrinsic inhibitor of mTOR kinase that also exerts an anti-apoptotic function. We aimed to explain these contradictory aspects of FKBP8 in cancer by identifying a "switch" type regulator. We identified through immunoprecipitation-mass spectrometry-based proteomic analysis that the mitochondrial protein prohibitin 1 (PHB1) specifically interacts with FKBP8. Furthermore, the downregulation of PHB1 inhibited the proliferation of ovarian cancer cells and the mTOR signaling pathway, whereas the FKBP8 level in the mitochondria was substantially reduced. Moreover, concomitant with these changes, the interaction between FKBP8 and mTOR substantially increased in the absence of PHB1. Collectively, our finding highlights PHB1 as a potential regulator of FKBP8 because of its subcellular localization and mTOR regulating role.

AIM:To explore the effects of galectin-3 (GAL-3) on the viability, migration and inflammation of human umbilical vein endothelial cells (HUVECs) and the mechanisms.METHODS:The HUVECs were cultured in vitro and treated with GAL-3 recombinant protein at 2 mg/L or GAL-3 short hairpin RNA (shRNA).The HUVECs were divided into normal group, recombinant GAL-3 group, shControl group and GAL-3-shRNA group.The mRNA expression of GAL-3, monocyte chemotactic protein (MCP)-1, IL-6, matrix metalloproteinase (MMP)-9 and cyclin D1 was detected by real-time quantitative PCR,and the protein expression of GAL-3, IL-6 and MCP-1 was detected by Western blot.The secretion levels of MCP-1 and IL-6 in the culture medium were measured by ELISA.The viability and the ability of migration of the HUVECs were examined by CCK-8 assay and wound healing assay.The protein levels of heat shock protein 90 (HSP90), ERK1/2, p-ERK1/2, JNK and p-JNK were determined by Western blot.RESULTS:The expression of GAL-3, MCP-1 and IL-6 at mRNA and protein levels, the mRNA expression of MMP-9 and cyclin D1, and the secretion levels of MCP-1 and IL-6 in the culture medium were significantly higher than those in normal group (P<0.05) after the HUVECs were treated with GAL-3 recombinant protein.However, these molecules mentioned above in GAL-3-shRNA group were significantly lower than those in normal group and negative control group (P<0.05).Compared with normal group, the viability and migration ability of the HUVECs in recombinant GAL-3 group were significantly increased, but the viability and migration ability of the HUVECs in GAL-3-shRNA group were lower than those in normal group and shControl group (P<0.05).In addition, the protein levels of p-ERK1/2 and HSP90 in recombinant GAL-3 group were higher than those in normal group (P<0.05), but those in GAL-3-shRNA group were lower than those in normal group and shControl group (P<0.05).The protein level of p-JNK was not oviously changed among the 4 groups.CONCLUSION:GAL-3 is involved in regulating the cell growth, migration and the release of inflammatory cytokines in vascular endothelial cells, which may be mediated by HSP90-ERK1/2 signaling pathway.

Expression of AMH in the serum of patients with ovarian endometriosis cyst and its clinical significance / 中国综合临床

Objective To investigate the expression of anti mullerian hormone(AMH)in the serum of patients with ovarian endometriosis cyst and its clinical significance.Methods Fifty-one cases of ovarian endometriosis cyst from March 2014 to June 2016 in Maternal and Child Health Hospital Affiliated to Southern Medical University(observation group)and thirty-five cases of normal women who were diagnosed through physical examination(control group)were selected as the research objects.The observation group patients received laparoscopic ovarian endometriosis cystectomy treatment,enzyme-linked immunosorbent assay(ELISA) was applied to detect and analyze serum AMH in the control group at physical examination and in the observation group before surgery and at 1 month,3 months after surgery.Results (1)The preoperative serum AMH level of the observation group was significantly lower than that of the control group,the difference was statistically significant((2.45±0.68)μg/L vs.(3.75±0.80)μg/L,t=7.8604,P=0.0000).(2)Serum AMH level in the groups where the ages were above 35years was significantly lower than that of the age less than 35 group( (1.76±0.57)μg/L vs.(3.61±0.88)μg/L,t=9.1249,P=0.0000); the preoperative serum AMH level in the group where disease course was more than 12 months was significantly lower than that of the disease course less than 12 months group((2.03 ± 0.64)μg/L vs.(3.98 ± 0.91)μg/L,t=8.1408,P=0.0000); the preoperative serum AMH level in patients with dysmenorrhea was significantly lower than that of patients without dysmenorrhea((1.65±0.53)μg/L vs.(3.91±0.84)μg/L,t=11.7861,P=0.0000),the preoperative serum AMH level in the bilateral lesion group was significantly lower than that of the unilateral lesion((2.01±0.68) μg/L vs.(2.84±0.72)μg/L,t=4.2174,P=0.0001); there was no significant difference in the preoperative serum AMH level between patients with<5.0 cm diameter cyst and patients with smaller cyst((2.52 + 0.81)μg/L vs.(2.39 + 0.50)μg/L,t=0.8411,P=0.4029).The serum AMH level in the observation group at 3 months after surgery was significantly lower than that before surgery((2.45±0.68)μg/L vs.(1.81± 0.55) μg/L,t=24.3657,P=0.0000).Conclusion The expression of serum AMH level in patients with ovarian endometriosis is low,and it is closely related to the age,course of disease,history of dysmenorrhea and the location of the lesion.Laparoscopic ovarian cystectomy may reduce ovarian reserve capacity in patients with ovarian endometriosis.
