RESUMEN

Translation is a crucial process during plant growth and morphogenesis. In grapevine (Vitis vinifera L.), many transcripts can be detected by RNA sequencing; however, their translational regulation is still largely unknown, and a great number of translation products have not yet been identified. Here, ribosome footprint sequencing was carried out to reveal the translational profile of RNAs in grapevine. A total of 8291 detected transcripts were divided into four parts, including the coding, untranslated regions (UTR), intron, and intergenic regions, and the 26 nt ribosome-protected fragments (RPFs) showed a 3 nt periodic distribution. Furthermore, the predicted proteins were identified and classified by GO analysis. More importantly, 7 heat shock-binding proteins were found to be involved in molecular chaperone DNA J families participating in abiotic stress responses. These 7 proteins have different expression patterns in grape tissues; one of them was significantly upregulated by heat stress according to bioinformatics research and was identified as DNA JA6. The subcellular localization results showed that VvDNA JA6 and VvHSP70 were both localized on the cell membrane. Therefore, we speculate that DNA JA6 may interact with HSP70. In addition, overexpression of VvDNA JA6 and VvHSP70, reduced the malondialdehyde (MDA) content, improved the antioxidant enzyme activity of superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD), increased the content of proline, an osmolyte substance, and affected the expression of the high-temperature marker genes VvHsfB1, VvHsfB2A, VvHsfC and VvHSP100. In summary, our study proved that VvDNA JA6 and the heat shock protein VvHSP70 play a positive role in the response to heat stress. This study lays a foundation for further exploring the balance between gene expression and protein translation in grapevine under heat stress.

RESUMEN

OBJECTIVE@#To investigate the development present situation of the department of critical care medicine in Inner Mongolia Autonomous Region (hereinafter referred to as Inner Mongolia), in order to promote the standardized and homogeneous development of critical care medicine in Inner Mongolia, and also provide a reference for discipline construction and resource allocation.@*METHODS@#A survey study was conducted in comprehensive intensive care unit (ICU) of tertiary and secondary hospitals in Inner Mongolia by online questionnaire survey and telephone data verification. The questionnaire was based on the Guidelines for the Construction and Management of Intensive Care Units (Trial) (hereinafter referred to as the Guidelines) issued by the National Health Commission in 2009 and the development trend of the discipline. The questionnaire covered six aspects, including hospital basic information, ICU basic information, personnel allocation, medical quality management, technical skill and equipment configuration. The questionnaire was distributed in September 2022, and it was filled out by the discipline leaders or department heads of each hospital.@*RESULTS@#As of October 24, 2022, a total of 101 questionnaires had been distributed, 85 questionnaires had been recovered, and the questionnaire recovery rate had reached 84.16%, of which 71 valid questionnaires had been collected in a total of 71 comprehensive ICU. (1) There were noticeable regional differences in the distribution of comprehensive ICU in Inner Mongolia, with a relatively weak distribution in the east and west, and the overall distribution was uneven. The development of critical care medicine in Inner Mongolia was still lacking. (2) Basic information of hospitals: the population and economy restricted the development of ICU. The average number of comprehensive ICU beds in the western region was only half of that in the central region (beds: 39.0 vs. 86.0), and the average number of ICU beds in the eastern region was in the middle (83.6 beds), which was relatively uneven. (3) Basic information of ICU: among the 71 comprehensive ICU surveyed, there were 44 tertiary hospitals and 27 secondary hospitals. The ratio of ICU beds to total beds in tertiary hospitals was significantly lower than that in secondary hospitals [(1.59±0.81)% vs. (2.11±1.07)%, P < 0.05], which were significantly lower than the requirements of the Guidelines of 2%-8%. The utilization rate of ICU in tertiary and secondary hospitals [(63.63±22.40)% and (44.65±20.66)%, P < 0.01] were both lower than the bed utilization rate required by the Guidelines (75% should be appropriate). (4) Staffing of ICU: there were 376 doctors and 1 117 nurses in tertiary hospitals, while secondary hospitals had 122 doctors and 331 nurses. There were significant differences in the composition ratio of the titles of doctors, the degree of doctors, and the titles of nurses between tertiary and secondary hospitals (all P < 0.05). Most of the doctors in tertiary hospitals had intermediate titles (attending physicians accounted for 41.49%), while most of the doctors in secondary hospitals had junior titles (resident physicians accounted for 43.44%). The education level of doctors in tertiary hospitals was generally higher than that in secondary hospitals (doctors: 2.13% vs. 0, masters: 37.24% vs. 8.20%). The proportion of nurses in tertiary hospitals was significantly lower than that in secondary hospitals (17.01% vs. 24.47%). The ratio of ICU doctors/ICU beds [(0.64±0.27)%, (0.59±0.34)%] and ICU nurses/ICU beds [(1.76±0.56)%, (1.51±0.48)%] in tertiary and secondary hospitals all failed to meet the requirements above 0.8 : 1 and 3 : 1 of the Guidelines. (5) Medical quality management of ICU: compared with secondary hospitals, the proportion of one-to-one drug-resistant bacteria care in tertiary hospitals (65.91% vs. 40.74%), multimodal analgesia and sedation (90.91% vs. 66.67%), and personal digital assistant (PDA) barcode scanning (43.18% vs. 14.81%) were significantly higher (all P < 0.05). (6) Technical skills of ICU: in terms of technical skills, the proportion of bronchoscopy, blood purification, jejunal nutrition tube placement and bedside ultrasound projects carried out in tertiary hospitals were higher than those in secondary hospitals (84.09% vs. 48.15%, 88.64% vs. 48.15%, 61.36% vs. 55.56%, 88.64% vs. 70.37%, all P < 0.05). Among them, the placement of jejunal nutrition tube, bedside ultrasound and extracorporeal membrane oxygenation were mainly completed independently in tertiary hospitals, while those in secondary hospitals tended to be completed in cooperation. (7) Equipment configuration of ICU: in terms of basic equipment, the ratio of the total number of ventilators/ICU beds in tertiary and secondary hospitals [0.77% (0.53%, 1.07%), 0.88% (0.63%, 1.38%)], and the ratio of injection pump/ICU beds [1.70% (1.00%, 2.56%), 1.25% (0.75%, 1.88%)] didn't meet the requirements of the Guidelines. The equipment ratio was insuffcient, which means that the basic needs of development had not been met yet.@*CONCLUSIONS@#The development of comprehensive ICU in Inner Mongolia has tended to mature, but there is still a certain gap in the development scale, personnel ratio and instruments and equipment compared with the Guidelines. Moreover, the comprehensive ICU appears the characteristics of relatively weak eastern and western regions, and the overall distribution is uneven. Therefore, it is necessary to increase efforts to invest in the construction of the department of critical care medicine.

RESUMEN

The brain-computer interface (BCI) systems used in practical applications require as few electroencephalogram (EEG) acquisition channels as possible. However, when it is reduced to one channel, it is difficult to remove the electrooculogram (EOG) artifacts. Therefore, this paper proposed an EOG artifact removal algorithm based on wavelet transform and ensemble empirical mode decomposition. Firstly, the single channel EEG signal is subjected to wavelet transform, and the wavelet components which involve EOG artifact are decomposed by ensemble empirical mode decomposition. Then the predefined autocorrelation coefficient threshold is used to automatically select and remove the intrinsic modal functions which mainly composed of EOG components. And finally the 'clean' EEG signal is reconstructed. The comparative experiments on the simulation data and the real data show that the algorithm proposed in this paper solves the problem of automatic removal of EOG artifacts in single-channel EEG signals. It can effectively remove the EOG artifacts when causes less EEG distortion and has less algorithm complexity at the same time. It helps to promote the BCI technology out of the laboratory and toward commercial application.

RESUMEN

The main pathophysiological changes of acute respiratory distress syndrome (ARDS) are massive destruction of pulmonary vascular endothelial barrier, pulmonary edema, infiltration of inflammatory cells, and refractory hypoxemia in severe cases. Pyroptosis is programmed cell necrosis, triggered by caspase and mediated by proteins in a member of conserved protein family Gasdermin D (GSDMD), which manifests as continuous cell expansion until cell membrane rupture, leading to release of cell contents and activation of a strong inflammatory response. Pyroptosis plays a key role in the development of septic ARDS. In this paper, the molecular mechanism of pyroptosis and the related researches on pyroptosis and ARDS are reviewed.

RESUMEN

Objective To investigate the factors influencing hepatitis B virus (HBV) reactivation in patients with HBV-related liver cancer after receiving transarterial chemoembolization (TACE) in order to prevent HBV reactivation and liver function damage, and to improve the clinical ways and means of TACE to provide reliable basis for the further improvement of curative effect. Methods A total of 80 patients with HBV-related liver cancer, who were admitted to authors' hospital during the period from January 2015 to August 2016, were collected. The gender, age, preoperative liver function classification, preoperative HBV DNA load, portal vein tumor thrombus, number of tumor lesions, the amount of used gelatin sponge, the amount of used microsphere, and the amount of lipiodol used in operation, etc. were recorded, and the results were statistically analyzed. Results Single factor analysis showed that higher preoperative HBV DNA load, the large amount of lipiodol used in operation and the presence of portal vein tumor thrombus were significantly related to the reactivation of HBV, but other factors had no significant relationship with the reactivation of HBV. Multivariate analysis indicated that higher preoperative HBV DNA load and the used dosage of lipiodol in operation >10 ml were the greatest risk factors for reactivation of HBV. Conclusion Reactivation of HBV in patients with HBV-related liver cancer can be induced by TACE, especially in the patients who have higher preoperative HBV DNA load and portal vein tumor thrombus, and also in whom the dosage of lipiodol used in operation is larger. Therefore, in order to prevent HBV reactivation and liver function injury the indications and contraindications of TACE should be strictly observed, the active antiviral therapy should be adopted before and after TACE, and the amount of lipiodol should be strictly controlled during the operation.

RESUMEN

Severe acute pancreatitis (SAP) is still with a high incidence and mortality. Early onset is usually non-infectious inflammation caused by systemic inflammatory response syndrome (SIRS), with the further progress into pancreatic necrosis, which is the main cause of death. The occurrence of infection can induce or aggravate multiple organ failure (MOF), leading to death. Therefore, whether early use of antibiotics to prevent the occurrence of pancreatic infection and how to identify early pancreatic infection, how to choose the start of antibiotic therapy is the hot and difficult point of current study. Although multiple versions of the acute pancreatitis (AP) treatment guidelines don't recommend to prevent the use of antibiotics, its compliance in clinical practice is not high, which is explored in clinical research. This paper summarized the progress on research status of antibiotics for AP, to provide basis for the establishment of treatment of AP.

RESUMEN

Aim To investigate whether ulinastatin has a beneficial effect on lipopolysaccharide( LPS) induced acute respiratory distress syndrome ( ARDS ) in rats, and to explore the possible underlying mechanisms. Methods Fifty-six Wistar rats were randomly as-signed into control group, model group( LPS 6,12,24 h groups), ulinastatin group(UTI 6,12,24 h groups), with 8 in each group. ARDS rat model was reproduced by intraperitoneal injection of LPS ( 10 mg · kg-1 ) , The rats in UTI groups were injected ulinastatin (20 000 u·kg-1), The rats in the control group re-ceived an equal volume of normal saline at the same time, rats in each group were sacrificed at 6,12,24 hours after LPS challenge. Plasma and lung tissue sam-ples were collected, Histopathological evaluation, lung wet/dry (W/D) ratio, Tumor necrosis factor-a(TNF-α) , Interleukin-18 ( IL-18 ) , surfactant protein A ( SPA) , malondialdehyde ( MDA ) , nitric oxide ( NO ) and superoxide dismutase( SOD) were analyzed. Immu-nohistochemical method was performed to detect the protein expression of p38MAPK and ERK. Western blot method was used to detect lung phosphorylated p38 MAPK ( p-p38 MAPK ) and pERK protein expres-sion changes. Result In the control groups, lung tis-sue showed a normal structure and clear pulmonary al-veoli under a light microscope. In the model group, ARDS characters such as extensive thickening of the alveolar wall, significant infiltration of inflammatory cells, demolished structure of pulmonary alveoli, and hemorrhage were found. In the all UTI treatment groups, these pathological changes in lung were markedly alleviated compared with those of LPS-in-duced ARDS group. Compared with control groups, lung W/D ratio, tumor necrosis factor-a ( TNF-α) , in-terleukin-18 ( IL-18 ) and surfactant protein A ( SPA ) in plasma ,and lung MDA,NO levels in lung homogenates in the LPS group were increased significantly, while the lung SOD levels in the LPS group were decreased. Compared with the LPS group, lung W/D ratio, TNF-aIL-18 and ( SPAin plasma , and lung MDA levels in lung homogenates in the UTI groups were decreased significantly, while the lung SOD levels in the UTI groups were increased. Immunohistochemistry showed that positive expressions of p38 MAPK and ERK in cy-toplasm and nucleus in the ulinastatin treatment groups were significantly lower than those in the model group. Western blot showed that compared with the control group, the p-p38MAPK and pERK protein expression in LPS group were significantly increased, and the uli-nastatin could inhibit the protein expressions compared with model group. Conclusion Ulinastatin can signifi-cantly ameliorate the lung injury induced by LPS in rats via the intervention of p38 MAPK and ERK signa-ling pathway and reducing inflammation and antioxidant effect.

RESUMEN

BACKGROUND:Reduction quality is essential for the healing and function of limb. Traditional X-ray and CT scans have some limitationsin quantitatively and visualy observing the reduction quality of the remnant fracture in three-dimensional displacements. Mimics have advantages in bone rapid modeling and three-dimensional measurement, which offers the chance in quantifying the reduction quality of the displacement in three-dimensional methods. OBJECTIVE:To measure residual displacement in femoral neck fracture patients with satisfactory reduction by using three-dimensional measurement method, and to evaluate the association between residual displacement and femoral head necrosis. METHODS:We enroled 141 patients with femoral neck fracture, who were treated in the Third Department of Joint, Affiliated Hospital of Logistics University of People’s Armed Police Force from January 2012 to December 2013. Al patients were divided into undisplaced fracture group (n=44; Garden1&2) and displaced fracture group (n=97; Garden3&4). Based on DICOM data of CT files, three-dimensional models were constructed in each patient. Three parameters were measured: displacement of femoral head’s center, fossa capitis femoris and rotational displacement. Femoral head necrosis was folowed up. The correlation between residual displacement and femoral head necrosis was explored. RESULTS AND CONCLUSION:(1) The duration of folow-up in those patients ranged from 25 to 43 months. Femoral head necrosis occurred in 7 cases from the undisplaced fracture group and 21 cases from the displaced fracture group. (2) The three parameters (displacement of femoral head’s center, fossa capitis femoris and rotational displacement) were respectively (7.44±2.84) mm, (11.75±4.12) mm and (17.68±8.99)° in the undisplaced group, and (6.51±3.75) mm, (9.34±5.27) mm and (14.67±7.43)° in the displaced group. Except displacement of femoral head’s center, significant differences in the other two parameters were detected between the two groups (P< 0.05). (3) These findings suggest that poor reduction quality is the main factor causing femoral head necrosis. X ray is insufficient to describe the spatial shift and the angle, and has limitations in assessing the reductionquality of femoral neck fracture. Three-dimensional measurement has certain advantages to assess quality of fracture reduction.

RESUMEN

Aim To investigate the molecular mecha-nism for the inhibitory effect of puerarin on IL-6 secre-tion in human osteoblast-likeMG-63 cells. Methods According to our previous studies, human osteoblast-like MG-63 cells containing two estrogen receptor ( ER) isoforms are a suitable model for this study. En-zyme-linked immnosorbent assay (ELISA), RT-PCR, luciferase reporter assay and small interfering RNA were performed to investigate the effect of puerarin on IL-6 expression in osteoblast-derived cells and underly-ing molecular mechanism. Results Puerarin could obviously inhibit IL-6 expression and IL-6 promoter ac-tivity by human osteoblastic MG-63 cells. Treatment with the ER antagonist ICI 182,780 abrogates the a-bove actions of puerarin on osteoblast-derived cells. U-sing siRNA technology, we further demonstrated that the effects of puerarin on IL-6 production were media-ted by ERα. Conclusion The effect of puerarin on IL-6 production in osteoblast is mediated by ERα.

RESUMEN

AIM:To observe the change of nitric oxide(NO)and hydrogen sulfide(H_2S)in blood and lung homogenate of hypoxic pulmonary hypertension(HPH)rat model,and to discuss the meaning of inhalation sodium nitrite and these factors in the treatment of HPH. METHODS:Fifty healthy male Wistar rats were assigned randomly into 5 groups(10 rats each):normoxia control group(NC),normoxia sodium nitrite group(NNI),hypoxic control group(HC),hypoxic normal saline group(HNS)and hypoxic sodium nitrite group(HNI). The mean pulmonary arterial pressure(mPAP),weight of right ventricle,weight of left ventricle plus septum,and the ratio of the weight of right ventricle to that of left ventricle plus septum(right ventricle hypertrophy index,RVHI)were also determined. The serum level of NO and plasma level of H_2S were measured,and at the same time the levels of NO in the lung homogenate were detected. The structures in pulmonary arteries were examined using optical microscope. RESULTS:After model established,compared to that in the normoxia groups,the body weight decreased significantly in hypoxia groups(P<0.05),although no difference of body weight in five groups before producing model was observed. Compared to that in normoxia groups,the levels of mPAP and RVHI increased significantly in hypoxia groups,and compared to that in hypoxia control groups and hypoxia normal saline group,mPAP and RVHI levels decreased significantly in hypoxia sodium nitrite group(P<0.05). Compared to that in normoxia groups,the serum level of NO decreased significantly in hypoxia groups(P<0.05). NO level in lung homogenate decreased significantly in hypoxia control group and hypoxia normal saline group as compared to that in normoxia groups(P<0.05),and no obvious difference between hypoxic sodium nitrite group and normoxia groups was found. The plasma level of H_2S was decreased significantly in hypoxia groups(P<0.05)as compared to that in normoxia groups. H_2S level increased significantly in hypoxia sodium nitrite group as compared to that in hypoxia control groups and hypoxia normal saline group(P<0.05). Observation under optical microscope,the lumen structure of lung in normoxia control group was normal. No significant change in normoxia sodium nitrite group was found. The proliferation of smooth muscle cells(SMCs),the collagen fiber deposition in the vessel wall and every caliber thickening was observed in hypoxic control group. The same changes were also observed in hypoxic normal saline group. The thickened caliber was relieved significantly in hypoxic nitrite group. CONCLUSION:Pulmonary hypertension and right ventricle reconstitution can be relieved by inhalation of sodium nitrite,and can be regulated by the level of NO and H_2S in rats. Above all,inhalation of sodium nitrite may degrade HPH directly or by affecting the externalization and synthesizing of gas signaling molecule indirectly.
