ABSTRACT

Rubi Fructus is a commonly used traditional Chinese medicine. The origin of Rubi Fructus is the dried fruit of Rubus chingii, a plant of the family Rosaceae, according to the 2015 edition of Chinese pharmacopoeia. There are some differences in the plant origin of Rubi Fructus in ancient herbal literature, to trace back its sources, we conducted a textual research on its origin, producing areas, quality evaluation, processing and concocting, properties, tastes and efficacy etc. based on the records of ancient herbal literatures and combined with plant morphology and related investigation. RESULTS:: showed that the variety of Rubi Fructus was more complex among ancient herbal literature, including R. coreanus, R. hirsutus, R. corchorifolius, R. foliolosus and other mixed varieties. Most scholars believe that the R. chingii has not been recorded in ancient herbal literature, while R. chingii was recorded as early as the Ming Dynasty in Compendium of materia medica through our textual research. Ancient Chinese herbs recorded that Rubi Fructus was mostly produced in Hubei, Shandong, Shanxi and Jiangsu provinces, while R. chingii mainly produced in Anhui, Jiangsu, Zhejiang, Jiangxi, Fujian and other provinces nowadays. Also, it was recorded that Rubi Fructus harvested in wheat field during May were the best. Besides, R. chingii with big, full, grain integrate, firm, yellow and green color, sour taste and impurity free possess the best quality in the contemporary. The ancient records of processing and concocting, properties, tastes and efficacy were basically the same as modern ones.These results provide the basis for the correct utilization and further development of Rubi Fructus.

ABSTRACT

BACKGROUND: Quizalofop-p-ethyl (QPE), a unitary R configuration aromatic oxyphenoxypropionic acid ester (AOPP) herbicide, was widely used and had led to detrimental environmental effects. For finding the QPEdegrading bacteria and promoting the biodegradation of QPE, a series of studies were carried out. RESULTS: A QPE-degrading bacterial strain YC-XJ1 was isolated from desert soil and identified as Methylobacterium populi, which could degrade QPE with methanol by cometabolism. Ninety-seven percent of QPE (50 mg/L) could be degraded within 72 h under optimum biodegradation condition of 35°C and pH 8.0. The maximum degradation rate of QPE was 1.4 mg/L/h, and the strain YC-XJ1 exhibited some certain salinity tolerance. Two novel metabolites, 2-hydroxy-6-chloroquinoxaline and quinoxaline, were found by high-performance liquid chromatography/mass spectroscopy analysis. The metabolic pathway of QPE was predicted. The catalytic efficiency of strain YC-XJ1 toward different AOPPs herbicides in descending order was as follows: haloxyfop-pmethyl ≈ diclofop-methyl ≈ fluazifop-p-butyl N clodinafop-propargyl N cyhalofop-butyl N quizalofop-p-ethyl N fenoxaprop-p-ethyl N propaquizafop N quizalofop-p-tefuryl. The genome of strain YC-XJ1 was sequenced using a combination of PacBio RS II and Illumina platforms. According to the annotation result, one α/ß hydrolase gene was selected and named qpeh1, for which QPE-degrading function has obtained validation. Based on the phylogenetic analysis and multiple sequence alignment with other QPE-degrading esterases reported previously, the QPEH1 was clustered with esterase family V. CONCLUSION: M. populi YC-XJ1 could degrade QPE with a novel pathway, and the qpeh1 gene was identified as one of QPE-degrading esterase gene.

ABSTRACT

OBJECTIVE@#To explore the changes in bone height of the maxillary sinus floor at different sinus ridge heights after transcrestal sinus floor elevation (tSFE) with the simultaneous implantation of short implants.@*METHODS@#A total of 74 Bicon short implants were implanted into 37 patients during the same period of maxillary sinus elevation. The residual bone height (RBH)<4 mm group has 43 sites, and the RBH≥4 mm group has 31 sites. After 5 years of follow-up observation, the implant survival rate and the change in bone height achieved in the maxillary sinus over time were measured and analyzed via clinical examination and X-ray imaging.@*RESULTS@#In the 74 implantation sites, the elevation height of the sinus floor was (6.64±1.32) mm and the bone height of the sinus floor was (3.35±1.29) mm 5 years after loading. No statistical difference was observed in the bone resorption of the implant neck between the RBH<4 mm and RBH≥4 mm groups. Meanwhile, a statistical difference was noted in the bone height obtained in the maxillary sinus between the two groups.@*CONCLUSIONS@#When RBH in the maxillary posterior tooth area was <4 mm, the simultaneous implantation of Bicon short implants with tSFE can achieve a high implant survival rate and bone gain in the maxillary sinus, but does not increase the absorption of the alveolar ridge bone.

ABSTRACT

@#[Abstract] Objective: To investigate the effect and mechanism of sevoflurane on the proliferation and invasion of colon cancer SW480 cells and the growth of transplanted tumor in nude mice by regulating the phosphorylation of PI3K. Methods: Colon cancer SW480 cells were treated with sevoflurane and randomly divided into control group, 0.5% sevoflurane group, 1.0% sevoflurane group and 2.0% sevoflurane group for subsequent experiments. The proliferation ability of SW480 cells was detected by Clone formation assay, mRNA expression levels of MDM2 and survivin in cells were detected by RT-PCR, invasion ability of cells was detected by Transwell assay, and protein expression levels of MDM2, survivin, VEGF, PI3K, p-PI3K, AKT and p-AKT were detected by Western blotting. PI3K activator 740Y-P was added for verification. SW480 cell transplanted tumor model was constructed on nude mice, and the tumor mass was weighed. The positive expression rates of MDM2 and VEGF in the transplanted tumor tissues were detected by Immunohistochemistry. Results: As compared with the control group and the low-dose group, the clone formation rate of SW480 cells and the number of invaded cells in the 1.0% and 2.0% sevoflurane groups were significantly decreased (all P<0.01), the mRNA and protein levels of MDM2 in the cells were significantly increased (all P<0.01), while the mRNA and protein levels of survivin were significantly decreased (all P<0.01); and the protein levels of VEGF, p-PI3K/PI3K and p-AKT/AKT were significantly decreased (all P<0.01). 740Y-P could reverse the effect of sevoflurane on the proliferation, invasion and expression of proteins associated with the PI3K/AKT signaling pathway in SW480 cells. The mass of transplanted tumor in 2.0% sevoflurane group was significantly decreased (P<0.01), and the positive MDM2 expression rate in tumor tissues was significantly increased (P<0.01), while the positive VEGF expression rate was significantly decreased (P<0.01). Conclusion: Sevoflurane inhibits the proliferation and invasion of colon cancer SW480 cells and the growth of xenografts in nude mice possibly by inhibiting PI3K phosphorylation.

ABSTRACT

SUMMARY OBJECTIVE Lung cancer is the leading cause of cancer-related death. To reduce lung cancer mortality and detect lung cancer in early stages, low dose CT screening is required. A meta-analysis was conducted to verify whether screening could reduce lung cancer mortality and to determine the optimal screening program. METHODS We searched PubMed, Web of Science, Cochrane library, ScienceDirect, and relevant Chinese databases. Randomized controlled trial studies with participants that were smokers older than 49 years (smoking >15 years or quit smoking 10 or 15 years ago) were included. RESULTS Nine RCT studies met the criteria. LDCT screening could find more lung cancer cases (RR=1.58, 95%CI=1.25-1.99, P<0.001) and more stage I lung cancers (RR=3.45, 95%CI=2.08-5.72, P<0.001) compared to chest-X ray or the no screening group. This indicated a statistically significant reduction in lung-cancer-specific mortality (RR=0.84, 95%CI=0.75-0.95, P=0.004), but without a statistically reduction in mortality due to all causes (RR=1.26, 95%CI=0.89-1.78, P=0.193). Annually, LDCT screening was sensitive in finding more lung cancers. CONCLUSIONS Low-dose CT screening is effective in finding more lung cancer cases and decreasing the deaths from lung cancer. Annual low-dose CT screening may be better than a biennial screening to detect more early-stage lung cancer cases.


RESUMO OBJETIVO O câncer de pulmão é a principal causa de mortes relacionadas ao câncer. Para reduzir a mortalidade por câncer de pulmão e encontrar câncer de pulmão em um estágio inicial, é necessária uma triagem por tomografia de baixa dose. Uma meta-análise foi emitida para testemunhar se a triagem poderia reduzir a mortalidade por câncer de pulmão e investigar o melhor programa de triagem. MÉTODOS Pesquisamos PubMed, Web of Science, biblioteca Cochrane, ScienceDirect e relevante banco de dados chinês. Ensaios clínicos controlados aleatórios, em que os participantes eram fumantes com mais de 49 anos (tabagismo >15 anos ou parar de fumar 10 ou 15 anos atrás) foram incluídos. RESULTADOS Nove estudos RCT preencheram os critérios. O rastreamento de LDCT pôde encontrar mais cânceres de pulmão (RR=1,58, IC 95%=1,25-1,99, P<0,001) e mais cânceres de estágio I do pulmão (RR=3,45, IC 95%=2,08-5,72, P<0,001) em comparação com raio X do tórax ou nenhum grupo de triagem. Ele indicou uma redução estatisticamente significativa na mortalidade específica do câncer de pulmão (RR=0,84, IC 95%=0,75-0,95, P=0,004), mas sem uma redução estatisticamente significativa na mortalidade por todas as causas (RR=1,26, IC 95%=0,89-1,78, P=0,193). Anualmente, o rastreamento de LDCT foi sensível em encontrar mais cânceres de pulmão. CONCLUSÕES A triagem de TC de baixa dose é eficaz para encontrar mais cânceres de pulmão e diminuir as mortes por câncer de pulmão. Para encontrar mais cânceres de pulmão em estágio inicial, a triagem anual de tomografia de baixa dose pode ser melhor do que a triagem bianual.

ABSTRACT

Abstract Purpose: To investigate the protective effects of Polygonatum sibiricum polysaccharide (PSP) on acute heart failure (AHF) in rats. Methods: Sixty rats were randomly divided into control, model, and low-, middle- and high-dose PSP groups, 12 rats in each group. The low-, medium- and high-dose PSP groups were intragastrically administrated with 100, 200 and 400 mg/kg PSP for 5 days, respectively. On the sixth day, the AHF model was established by intraperitoneal injection of adriamycin. After 24h, the cardiac function, serum biochemical indexes, myocardial ATPase and succinate dehydrogenase levels and apoptosis related protein expressions were determined. Results: Compared with model group, in high-dose PSP group the heart rate, left ventricular systolic pressure, ±dp/dtmax, serum superoxide dismutase level, myocardial Na+-K+-ATPase, Ca2+-Mg2+-ATPase and succinate dehydrogenase levels and myocardial Bcl-2 and Caspase-3 protein expression levels were significantly increased (P<0.05), the left ventricular end diastolic pressure, serum cTnI, CK-MB, TNF-α, IL-6, malondialdehyde and nitric oxide levels and myocardial Bax and cleaved Caspase-3 protein expression levels were significantly decreased (P<0.05). Conclusions: Polysaccharide can prevent the acute heart failure induced by adriamycin. The mechanism may be related to its anti-oxidative stress, anti-inflammation and inhibition of cardiac myocyte apoptosis.

ABSTRACT

Gene networks have been broadly used to predict gene functions based on guilt by association (GBA) principle. Thus, in order to better understand the molecular mechanisms of esophageal squamous cell carcinoma (ESCC), our study was designed to use a network-based GBA method to identify the optimal gene functions for ESCC. To identify genomic bio-signatures for ESCC, microarray data of GSE20347 were first downloaded from a public functional genomics data repository of Gene Expression Omnibus database. Then, differentially expressed genes (DEGs) between ESCC patients and controls were identified using the LIMMA method. Afterwards, construction of differential co-expression network (DCN) was performed relying on DEGs, followed by gene ontology (GO) enrichment analysis based on a known confirmed database and DEGs. Eventually, the optimal gene functions were predicted using GBA algorithm based on the area under the curve (AUC) for each GO term. Overall, 43 DEGs and 67 GO terms were gained for subsequent analysis. GBA predictions demonstrated that 13 GO functions with AUC>0.7 had a good classification ability. Significantly, 6 out of 13 GO terms yielded AUC>0.8, which were determined as the optimal gene functions. Interestingly, there were two GO categories with AUC>0.9, which included cell cycle checkpoint (AUC=0.91648), and mitotic sister chromatid segregation (AUC=0.91597). Our findings highlight the clinical implications of cell cycle checkpoint and mitotic sister chromatid segregation in ESCC progression and provide the molecular foundation for developing therapeutic targets.

ABSTRACT

Cancer is the first cause of death in China. From traditional treatment to targeted therapy and again to immunotherapy, each step forward has brought us a new hope and some challenges as well. Effective antitumor immunotherapy relies on two aspects, breakdown of immunotolerance and maintenance of system immune homeostasis. Oncolytic viruses (OVs) are capable of selective replication in malignant cells and induction of their lysis and death. With a characterization of OVs, this review introduces the mechanisms of oncolytic immunotherapy and the Results of related studies.

ABSTRACT

<p><b>BACKGROUND</b>Acute minor ischemic stroke (AMIS) or transient ischemic attack (TIA) is a common cerebrovascular event with a considerable high recurrence. Prior research demonstrated the effectiveness of regular long-term remote ischemic conditioning (RIC) in secondary stroke prevention in patients with intracranial stenosis. We hypothesized that RIC can serve as an effective adjunctive therapy to pharmacotherapy in preventing ischemic events in patients with AMIS/TIA. This study aimed to investigate the feasibility, safety, and preliminary efficacy of daily RIC in inhibiting cerebrovascular/cardiovascular events after AMIS/TIA.</p><p><b>METHODS</b>This is a single-arm, open-label, multicenter Phase IIa futility study with a sample size of 165. Patients with AMIS/TIA receive RIC as an additional therapy to secondary stroke prevention regimen. RIC consists of five cycles of 5-min inflation (200 mmHg) and 5-min deflation of cuffs on bilateral upper limbs twice a day for 90 days. The antiplatelet strategy is based on individual physician's best practice: aspirin alone, clopidogrel alone, or combination of aspirin and clopidogrel. We will assess the recurrence rate of ischemic stroke/TIA within 3 months as the primary outcomes.</p><p><b>CONCLUSIONS</b>The data gathered from the study will be used to determine whether a further large-scale, multicenter randomized controlled Phase II trial is warranted in patients with AMIS/TIA.</p><p><b>TRIAL REGISTRATION</b>ClinicalTrials.gov, NCT03004820; https://www.clinicaltrials.gov/ct2/show/NCT03004820.</p>

ABSTRACT

OBJECTIVE To investigate the underlying mechanism of drug resistance to cisplatin and increasing the sensitivity to therapeutic drugs are key steps towards the improved treatment of patients with ovarian cancer. Gap junction (GJ) and connexin (Cx) are closely related to tumor formation, but the relationship between cisplatin resistance and GJ or Cx are undetermined. METHODS We established the cisplatin-resistant human ovarian cancer cell line A2780-CDDP over an 11-month period, with the concentration of cisplatin gradually increasing from 0.5 g·L-1 to 16 g·L-1. To explore the effect of GJ in the process of cisplatin resistance, we investigated GJ using a parachute dyecoupling assay in A2780- RI(1.2), A2780- RI(1.7), A2780- RI(2.9), A2780- RI(4.3) and A2780- CDDP cells. We further explored whether the Cxs responsible for GJ were related to cisplatin resistance. In A2780- RI(1.2), A2780-RI(1.7), A2780-RI(2.9), A2780-RI(4.3) and A2780-CDDP, we used q-PCR to analyze the levels of Cx43, Cx40, Cx37, and Cx32. To confirm the effect of Cx32 on cisplatin resistance, we knocked down Cx32 in A2780-CDDP cells with siRNA-Cx32. As GJ was decreased whereas Cx32 expression was elevated during the cisplatin resistance process, it drove us to explore the underlying mechanism. To resolve this issue, we extracted membrane-bound and cytoplasmic proteins from A2780 and A2780-CDDP cells. RESULTS Here we showed that cisplatin resistance was correlated to the loss of GJ and the upregulation of Cx32 expression. Enhancing GJ in A2780-CDDP cells could increase the apoptotic response to cisplatin treatment. Furthermore, although Cx32 expression was increased in A2780-CDDP cells, it was more localized to the cytoplasm rather than in the membrane, and knockdown of Cx32 in A2780-CDDP cells sensitized them to cisplatin treatment.

ABSTRACT

Objective To compare the clinical effects between sodium hyaluronate injection and absorbable medical film implantation with arthroscopic release in treatment of frozen shoulder. Methods 40 cases of frozen shoulder patients from September 2015 to December 2016, 20 cases of sodium hyaluronate injection with arthroscopic release (SH group), 20 cases of absorbable medical film implantation with arthroscopic release (Medical Film group), the visual analogue scale (VAS), the shoulder joint function scores of American Shoulder and Elbow Surgeons (ASES), and University of California at Los Angeles (UCLA) between the two groups were compared. Results After 6 months follow-up, the VAS score, ASES score and UCLA score of the two groups were significantly improved (P < 0.05), the difference of VAS score, ASES score and UCLA score between the two groups were not statistically significant. Conclusion The sodium hyaluronate injection and absorbable medical film implantation with arthroscopic release can improve the shoulder function, and there is no significant difference between them.

ABSTRACT

Objective @#To investigate the effectiveness of fluoride varnish in preventing first permanent molars caries inschool-age children and provide necessary information for oral health instruction. @*Methods@#378 children aged 6-7 years old in the first grade of primary school in dahua country, hechi city, Guangxi province (1 053 first permanent molars) were randomly recruited into 2 groups. The test group (542 first permanent molars in 191 children) was treated with fluoride varnish one time in a half year and given oral hygiene instruction 3 times; The control group (511 first permanent molars in 187 children) was only given oral hygiene instruction 3 times. All first permanent molars were checked after 18 months later for caries. @*Results@#After intervention, the caries prevalence rate in the test group raised from 21.99% to 27.75% compared with the control group from 24.60% to 37.43%. The caries incidence rate in test and control group was 5.76% and 12.83% respectively. There was a significant difference between 2 groups regardless of caries prevalence, caries incidence, the DMFT reduction, the DMFs reduction, the occlusal caries prevalence, the pit and fissure caries prevalence, the proximal caries prevalence. @*Conclusion @#Semi-annual application of fluoride varnish is effective in the prevention of dental caries in first permanent molars , which was worth of being popularized in clinic.

ABSTRACT

·AIM: To evaluate the effect of bupivacaine in non-catheter infiltration anesthesia during vitretomy operation.·METHODS:Fifty-eight patients (58 eyes) with vitreous retinal surgery were selected. Patients were randomly divided into observation group ( 28 eyes ) and control group ( 30 eyes ) . The observation group were received non-catheter infiltration anesthesia. The control group were received traditional Sub- Tenon's block ( STB ) . Degree of pain, basic vital signs, the duration of anesthesia and analgesia grade were recorded and compared between two groups.·RESULTS: No significant difference was found in the 11-point numeric rating scale ( NRS - 11 scoring ) of anesthesia process, sclera incision, intraocular operation and the end of operation between two groups (P>0. 05). The difference were not significant in heart rate and blood pressure between two groups(P>0. 05). There was statistically significant difference in the duration of anesthesia between two groups (P<0. 05).·CONCLUSION: Both groups can provide the same anesthetic effect. Compared to STB, non - catheter infiltration anesthesia takes short time, and it is a safe and effective anesthesia methods. In addition, compare to the mixture of bupivacaine and lidocaine injection, bupivacaine injection can provide the same anesthetic effect.
