Expression pattern of MMP-12 in long-term optic nerve regeneration induced by lens injury / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the expression changes of MMP-12 during the long-term axon regeneration induced by the lens injury after the optic nerve clamp trauma in sprague-dawley(SD)rats.METHODS: The optic nerve injury model and lens injury model of SD rats were established, and the 24 experimental animals were divided into control group; lens injury group; optic nerve injury group; lens injury combined with optic nerve injury group, with 6 rats in each group. Reference transcriptome sequencing was used to analyze the expression changes of differentially expressed genes in the injured optic nerve region, and relevant differentially expressed genes with high expression were screened. Quantitative real-time polymerase chain reaction(qRT-PCR)and enzyme-linked immunosorbent assay(ELISA)were used to quantify the expression changes of matrix metalloproteinase-12(MMP-12)in the injured optic nerve region.RESULTS: The Principal Component Analysis of transcriptome sequencing indicated that lens injury combined with optic nerve injury was the principal component of gene expression change. Analysis of gene expression differences showed that the expression of MMP-12 gene was up-regulated in the lens injury combined with optic nerve injury group. The mRNA expression level of MMP-12 in the lens injury combined optic nerve injury group was up-regulated compared with the control group, the optic nerve injury group and the lens injury group at 14d and 21d after successful modeling(P<0.05). At 7, 28d, there was no difference in expression among all groups. The protein expression level of MMP-12 in the lens injury combined with optic nerve injury group was up-regulated compared with the control group and optic nerve injury group at 7, 14 and 21d after successful modeling(P<0.05), and it was up-regulated in the lens injury group combined with optic nerve injury group compared with optic nerve injury group at 21d(P<0.05). At 28d, there was no difference in expression among all groups.CONCLUSION: The up-regulated expression of MMP-12 may be involved in the long-term regeneration of the optic nerve after lens injury.

Juglone induces proliferation inhibition and apoptosis of cervical cancer cells via promoting c-Myc ubiquitination / 南方医科大学学报

OBJECTIVE@#To observe the expression of c-Myc protein in cervical cancer HeLa cells and explore the effect of juglone on the proliferation and apoptosis of HeLa cells by affecting c-Myc ubiquitination.@*METHODS@#HeLa cells treated with different concentrations (0, 10, 20, or 50 μmol/L) of juglone or with 20 μmol/L juglone for different time lengths were examined for expression of c-Myc protein with Western blotting. The half-life of c-Myc protein was determined using cycloheximide (CHX) and c-Myc protein degradation was detected using coimmunoprecipitation. We also assessed the effects of 20 μmol/L juglone combined with 0, 1.0 or 2.0 μmol/L MG132 (a proteasome inhibitor) on c-Myc expression. The effects of 20 μmol/L juglone on the proliferation and apoptosis of HeLa cells with RNA interference-mediated knockdown of c-Myc were evaluated with MTT assay and flow cytometry.@*RESULTS@#Treatment with juglone significantly lowered c-Myc protein expression in HeLa cells in a concentration-and time-dependent manner (P < 0.05). Juglone obviously shortened the half-life of c-Myc protein, and the addition of MG132 significantly up-regulated the expression level of c-Myc protein (P < 0.05). Juglone treatment also promoted ubiquitination of c-Myc protein in HeLa cells. Compared with the cells transfected with a negative control construct, the cells transfected with si-c-Myc showed significantly decreased proliferation inhibition and a lowered cell rate with early apoptosis after juglone treatment (P < 0.05).@*CONCLUSION@#Juglone inhibits proliferation and promotes apoptosis of HeLa cells by affecting the ubiquitination of c-Myc protein.

Molecular authentication of the medicinal species of Rhizoma et Radix Heraclei, Radix Angelicae Sinensis, Radix Angelicae Pubescentis and Rhizoma et Radix Notopterygii by integrating ITS2 and its secondary structure / 药学学报

This study is to identify Chinese medicinal materials Rhizoma et Radix Heraclei, Angelicae Sinensis, Radix Angelicae Pubescentis and Rhizoma et Radix Notopterygii based on ITS2 and its secondary structure. Total 26 ITS sequences of 7 species were downloaded from GenBank, the ITS2 sequences were annotated by HMMer method. The NJ phylogenetic tree was built by MEGA software, the intraspecific and interspecific K2P genetic distance were analyzed by MEGA as well. The ITS2 secondary structures of all taxa were predicted by ITS2 database. Sequence matrix of primary structure and secondary structure was aligned by 4Sale software. And the profile neighbor joining (PNJ) phylogenetic tree was constructed via the the ProfDistS software based on the distance method. The results show that, the average interspecific genetic distance was far greater than the average intraspecific genetic distance, an obvious barcoding gap was noted among all taxa; NJ tree showed that all species were clustered into seperate branches; each species had different secondary structures; the PNJ tree showed higher resolution than NJ tree. Therefore, ITS2 is suggested to be used as a barcode for distinguishing the original plants of Rhizoma et Radix Heraclei, Radix Angelicae Sinensis, Radix Angelicae Pubescentis and Rhizoma et Radix Notopterygii in this study, this provides some scientific basis for classification and accurate identification of these Chinese medicinal materials.

The role of SIRT6 in nonalcoholic steatohepatitis / 生理学报

SIRT6, a member of the silencing information regulatory protein family, is a nicotinamide adenine dinucleotide-dependent histone deacetylase and an ADP-ribose transferase enzyme. It plays an important role in fundamental physiological and pathological processes, including lipid metabolism, inflammation, oxidative stress and fibrosis, and is considered as a potential therapeutic target for metabolic syndrome. SIRT6 knockout mice displayed severe fatty liver, and the expression of SIRT6 in the liver of nonalcoholic steatohepatitis (NASH) mice was significantly lower than that of normal mice. Overexpression of SIRT6 significantly ameliorated NASH-induced liver damage. It is suggested that SIRT6 may play a key role in protecting against NASH. In this paper, we review the important regulatory functions of SIRT6 in the occurrence and development of NASH.

Up-Regulation of MiR-1915 Inhibits Proliferation, Invasion, and Migration of Helicobacter pylori-Infected Gastric Cancer Cells via Targeting RAGE

PURPOSE: Helicobacter pylori (HP)-infected gastric cancer (GC) is known to be a fatal malignant tumor, but the molecular mechanisms underlying its proliferation, invasion, and migration remain far from being completely understood. Our aim in this study was to explore miR-1915 expression and its molecular mechanisms in regulating proliferation, invasion, and migration of HP-infected GC cells. MATERIALS AND METHODS: Quantitative real-time PCR and western blot analysis were performed to determine miR-1915 and receptor for advanced glycation end product (RAGE) expression in HP-infected GC tissues and gastritis tissues, as well as human gastric mucosal cell line GES-1 and human GC cell lines SGC-7901 and MKN45. CCK8 assay and transwell assay were performed to detect the proliferation, invasion, and migration capabilities. MiR-1915 mimics and miR-1915 inhibitor were transfected into GC cells to determine the target relationship between miR-1915 and RAGE. RESULTS: MiR-1915 was under-expressed, while RAGE was over-expressed in HP-infected GC tissues and GC cells. Over-expressed miR-1915 could attenuate cellular proliferation, invasion, and migration capacities. RAGE was confirmed to be the target gene of miR-1915 by bioinformatics analysis and luciferase reporter assay. Moreover, HP-infected GC cellular proliferation, invasion, and migration were inhibited after treatment with pcDNA-RAGE. CONCLUSION: MiR-1915 exerted tumor-suppressive effects on cellular proliferation, invasion, and migration of HP-infected GC cells via targeting RAGE, which provided an innovative target candidate for treatment of HP-infected GC.

Diagnostic Effects and Influence Factors of Emergency Colonoscopy in Patients with Acute Lower Gastrointestinal Massive Hemorrhage / 昆明医科大学学报

Objective To analyze the diagnostic effects and influence factors of emergency colonoscopy in patients with acute lower gastrointestinal massive hemorrhage. Methods 56 cases of patients with acute lower gastrointestinal massive hemorrhage treated in our hospital from May 2016 to May 2017 were selected and treated with emergency colonoscopy. The causes of acute lower gastrointestinal massive hemorrhage were analyzed and the emergency colonoscopy completion conditions in patients with different bowel preparation methods and different degrees of bleeding were compared. According to the results of emergency colonoscopy, the patients were divided into the successful test group and the failed test group, and the clinical data of the two groups were compared, and the influencing factors of the emergency colonoscopy were analyzed. Results The causes of acute lower gastrointestinal massive hemorrhage were colon cancer, colonic polyps,colon diverticulum and so on. There was no significant difference in the rebleeding or bleeding aggravation rate of different intestinal preparation methods (P＞0.05), and the detection rate of active bleeding in the severe hemorrhage group was higher than that in the mild hemorrhage group and the moderate hemorrhage group (P＜0.05) . In the emergency colonoscopy group, the number of patients in the successful test group, who were females, aged more than 45 years old, with a appendectomy history, a short walking time during the medication, an inadequate intestine preparation, unfinished lustramentum before examination, intestinal anatomical abnormalities and a non-standard physician operation,were lower than those in the failed test group (P＜0.05) . Logistic regression analysis showed that being female, aged over 45, inadequate bowel preparation and intestinal anatomical abnormalities were the independent risk factors for emergency colonoscopy failure in patients with acute lower gastrointestinal massive hemorrhage (P＜0.05) .Conclusions Emergency colonoscopy has important diagnostic significance for acute lower gastrointestinal massive hemorrhage especially the moderate to severe hemorrhage. Female, aged more than 45 years old, inadequate intestinal preparation and intestinal anatomical abnormalities are the independent influencing risk factor for diagnostic effects.

Application of PET/CT combined with 4DCT in radiotherapy of esophageal carcinoma / 重庆医学

Objective To study the correlation of positron emission tomography/computed tomography (PET/CT) under different standardized uptake value (SUV) thresholds and full time four-dimensional computed tomography (4DCT) in esophageal carcinoma target delineation and explore the optimum SUV value that can accurately reflect the spatial movement of the target.Methods Eighty-two patients with esophageal cancer initial treatment in this hospital were respectively performed the scanning localization by PET/CT and 4DCT on the same day.Then different SUV thresholds (≥2.0,2.5,3.0,3.5) and the percentage of maximum SUV value (≥20％ SUV 30％ SUV 40％ SUVmax) were selected to delineate the internal gross target volume (IGTV) PET/CT in PET/CT,the ten phases of the 4DCT were collected to obtain the full time target IGTV10,the target center offset,volume ratio and conformity index (CI) were compared between the two images,the relatively good SUV value with the registration in 4DCT target was picked out,then the correlation between the target center offset,volume ratio and CI with the IGTV10 volume,long axial diameter of IGTV10,displacement of head-to-foot direction and spatial motion was analyzed.Results When the SUV threshold was 2.0 or 20 ％ SUV the spatial matching degree of 4DCT and PET/CT images was better.The head-to-foot direction displacement and special motion displacement in the target center offset of IGTVPET2.0,IGTVPET20％ and IGTV10 showed the positive correlation (P＜0.05);the volume ratio had no correlation with the IGTV10 volume,IGTV10 long axial diameter,head-to-foot direction displacement and special motion displacement (P＞0.05);CI had positive correlation with IGTV10 volume and IGTV10 long axial diameter,while had negative correlation with the head-to-foot direction displacement and special motion displacement (P＜0.05).Conclusion When SUV taking 2.0 or 20％ SUV the esophageal carcinoma target volume of PET/CT is similar to that of full time 4DCT,but there are still some deviations in the conformity index,therefore the PET/CT threshold value and 4DCT time phase selection should be further studied.

A three-dimensional finite element analysis of the tip mechanical capabilities of self-ligating brackets with double wires / 中国组织工程研究

BACKGROUND: At present, the using of self-ligating brackets is more and more extensive. But it is unclear about the rules and mechanisms underlying the tooth control by double wires in three dimensions, especially in tipping.OBJECTIVE: Using the finite element method to establish different three-dimensional finite models of DamonQ brackets and archwires with different sizes, and then to explore the tip mechanical properties when using double wire technique. METHODS: Different three-dimensional finite models of DamonQ brackets and archwires with different sizes were established by Pro/E Wildfire5.0. The models were assembled and imported to MSC.Marc.Mentat2005R3 followed by simulating the tip load, calculating torque moment and drawing the corresponding graph and histogram. RESULTS AND CONCLUSION: (1) With tipping movement of single wire, tipping moment of auxiliary single archwires was multiplied by the same size as main archwires. (2) With tipping movement of double wires, the tip moment value increased when the size of the main or auxiliary archwire increased, and the influence of the size of the auxiliary archwire was greater than that of the main archwire. (3) When the tilt angle is large, we can simply level the tooth using the main archwire first, and then precisely adjust the tooth position with double wires. And in the clinical pratice, orthodontists can choose the appropriate size of double wires according to their needs.

Patients Aged 80 Years or Older are Encountered More Potentially Inappropriate Medication Use / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Polypharmacy and potentially inappropriate medications (PIMs) are prominent prescribing issues in elderly patients. This study was to investigate the different prevalence of PIM use in elderly inpatients between 65-79 years of age and 80 years or older, who were discharged from Geriatric Department in West China Hospital.</p><p><b>METHODS</b>A large-scale cohort of 1796 inpatients aged 65 years or over was recruited. Respectively, 618 patients were 65-79 years and 1178 patients were 80 years or older. Updated 2012 Beers Criteria by the American Geriatric Society was applied to assess the use of PIM among the investigated samples.</p><p><b>RESULTS</b>A review of the prescribed medications identified 686 patients aged 80 years or older consumed at least one PIM giving a rate of 58.2%. Conversely, 268 (43.4%) patients aged 65-79 years consumed at least one PIM (χ2 = 40.18, P < 0.001). Patients aged 80 years or older had higher hospitalization expenses, length of stay, co-morbidities, medical prescription, and mortality than patients aged 65-79 years (all with P < 0.001). Patients aged 80 years or older were prescribed with more benzodiazepines, drugs with strong anticholinergic properties, megestrol, antipsychotics, theophylline, and aspirin. In multiple regression analysis, PIM use was significantly associated with female gender, age, number of diagnostic disease, and number of prescribed medication.</p><p><b>CONCLUSIONS</b>The finding from this study revealed that inpatients aged 80 years or older encountered more PIM use than those aged 65-79 years. Anticholinergic properties, megestrol, antipsychotics, theophylline, and aspirin are medications that often prescribed to inpatients aged 80 years or older. Doctors should carefully choose drugs for the elderly, especially the elderly aged 80 years or older.</p>

Anti-apoptotic effect of Astragalus Polysaccharide on myeloid cells / 中国实验血液学杂志

This study was aimed to assess the effect of Astragalus Polysaccharide (ASPS) on in-vitro hematopoiesis. CFU-GM assays were used to determine the effect of ASPS and thrombopoietin (TPO) on granulocytic-monocyte progenitor cells. The CFU assays were also used to investigate the effect of ASPS on the proliferation of HL-60 cells.HL-60 cells were cultured with serum-free RPMI 1640 medium and treated with or without of different concentrations of ASPS. After 72 h incubation, the number of cells were counted.In addition, the caspase-3 and JC-1 expression was determined by flow cytometry with Annexin V/PI double staining. The results showed that ASPS (100, 200 µg/ml) and TPO (100 ng/ml) significantly promoted CFU-GM formation in vitro. Various concentrations of ASPS and TPO also promoted the colony formation of HL-60 cells, the largest effect of ASPS was observed at a concentration of 100 µg/ml. There were no synergistic effects between TPO and ASPS on cellular proliferation. The results also showed that ASPS significantly protected HL-60 cells from apoptosis in condition of serum-free medium culture, suppressed caspase 3 activation, and reduced the cell apoptosis. It is concluded that ASPS can significantly promote the formation of bone marrow CFU-GM and the proliferation of HL-60 cells, the optimal concentration of ASPS is at 100 µg/ml. In the absence of serum inducing apoptosis, ASPS also significantly reduced the apoptosis of HL-60 cells via suppressing the activation of caspase-3.

Objective To investigate the infection status of HIV/AIDS patients complicated with pneumocystis Carinii Poneumonia(PCP),and the role of CD4+ T lymphocyte in PCP.Methods PC was detected by Giemsa's staining and CD4+ T lymphocyte was counted by flow cytometry.Meanwhile,this text calculated and compared a series of indexes about PC infection,such as the total positive rate,the average annual positive rate,the average monthly positive rate,the positive rate between female and male,the positive rate between sputum and BALF specimens,and the relationship between the positive rate and CD4+ T lymphocyte count.Results The total positive rate about PC infection of the 1 806 eases of sputum specimens was 46.8％,and the incidence mainly from April to July during a year,and the positive rates were 46.3％ and 50.2％ for males and females respectively.The results showed that there were no significant differences when compared with the average annual positive rate ( P ＞ 0.05 ),but there were significant differences when compared with the average monthly positive rate ( P ＜ 0.05 ),the positive rate between female and male(P＞0.05),and among 3 formerly defined ranges of CD4+count(P ＜0.05).Conclusion Giemsa's staining showed the total positive rate was 46.8％ of the HIV/AIDS patients infected by PC with sputum specimens,which represented a seasonal fluctuation tendency.The positive rate of BALF was higher than that in sputum,and it increased with CD4+ count decreasing.Giemsa's staining was an efficient,simple and feasible way for PC detection and easy for generalization.Meanwhile,it is strongly relied on the operator's experience and skill.

Detection and clinical analysis of EV71,CA16 and respiratory virus con-infection in patients with hand,foot and mouse disease / 中华检验医学杂志

Objective To explore the situation of respiratory virus co-infection with EV71 and CA16 in patients with hand,foot and mouse disease(HFMD) ,and analyze the influence of co-infection on clinical aspects.Methods From June to October of 2010,there were 348 patients enrolled in the study,with 248 hospitalization cases and 100 mild outpatients.All the patients were diagnosed as HFMD in Beijing You-an Hospital.The viral RNA from the pharynx swab samples were extracted and reversely transcribed by RT-PCR.All the samples were detected with the EV71 and CA16 by real-time fluorescence quantitative PCR.Twelve kinds of respiratory viruses were detected by a commercial multiplex-PCR method.The PCR products were confirmed by electrophoresis.Chi square test was used in the data analysis.Results Of the 348 HFMD patients,36 subjects were detected as positive for respiratory virus co-infection.In the 248 hospitalization cases,111 cases were positive for EV71 or CA16,with eight cases identified with respiratory virus co-infection(7.2%); the other 137 cases were negative for EV71 and CA16,with eleven cases identified with respiratory virus co-infection(7.4%).There was not significant difference between respiratory virus co-infection and the identification of EV71 /CA16(x2 = 0.059,P ＞ 0.05).In the 100 mild outpatients positive for EV71 or CA16,seventeen cases were identified with respiratory virus co-infection(17%).The rate of respiratory virus co-infection in the mild outpatients was much higher than in the severe hospitalization patients(x2 = 4.830,P＜ 0.05).Among the 111 EV71(+) or CA16(+) inpatients,there were 101 cases diagnosed as severe cases(91.0%); similarly,there were 132 cases diagnosed as severe cases(96.4%) among the 137 EV71(-) CA16(-) cases.There was not difference between the identification of EV71/ CA 16 and illness of HFMD(x2 = 3.099,P ＞ 0.05).The leading respiratory virus being identified were HRV A/B,PIV3 and FLU A in the 348 HFMD patients.Conclusions Co-infection with respiratory virus exists in the HFMD patients. However,the respiratory virus infection has no significant influence to the state of HFMD illness.

Taxonomic reappraisal of Antithamnion sparsum Tokida (Ceramiaceae, Rhodophyta).

The taxonomic criterion of Antithamnion sparsum was reappraised in comparison with A. densum and A. defectum based on crossing experiments, morphological observation, chromosome study and Random Amplified Polymorphic DNA (RAPD) analysis. These species had a very similar morphology but were sexually isolated. The chromosome number was n = ca. 24 for A. densum, n = ca. 21 for A. defectum, and n = ca. 44 for A. sparsum. All isolates of A. sparsum and A. densum showed polysiphonia-type life history Asexual reproduction was induced by favorable environmental conditions. In A. sparsum, 1-2% of male plants developed mitotic tetrasporangia together with spermatangia. In A. densum, 5-10% of tetraspores developed into asexual tetrasporophytes. Phylogenetic relationships between these species were examined using RAPD analysis, and A. glanduliferum was used as an outgroup. A total of 167 polymorphic RAPD markers amplified from 15 different primers were analyzed. Results suggested that these species were closely related, with A. defectum placed in the middle of A. sparsum and A. densum. Chromosome study and RAPD analysis implied that A. sparsum first separated from A. defectum through polyploidization and later A. densum evolved. These species may present another example of the narrow species concept in the genus Antithamnion.
