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.

Color is an important indicator for evaluating the ornamental traits of horticultural plants, and plant pigments is a key factor affecting the color phenotype of plants. Plant pigments and their metabolites play important roles in color formation of ornamental organs, regulation of plant growth and development, and response to adversity stress. It has therefore became a hot topic in the field of plant research. Virus-induced gene silencing (VIGS) is a vital genomics tool that specifically reduces host endogenous gene expression utilizing plant homology-dependent defense mechanisms. In addition, VIGS enables characterization of gene function by rapidly inducing the gene-silencing phenotypes in plants. It provides an efficient and feasible alternative for verifying gene function in plant species lacking genetic transformation systems. This paper reviews the current status of the application of VIGS technology in the biosynthesis, degradation and regulatory mechanisms of plant pigments. Moreover, this review discusses the potential and future prospects of VIGS technology in exploring the regulatory mechanisms of plant pigments, with the aim to further our understandings of the metabolic processes and regulatory mechanisms of different plant pigments as well as improving plant color traits.

Objective To summarize the current status and trend of hypoglycemic agents of diabetic inpatients in different departments of Chinese PLA General Hospital.Methods The clinical data of diabetic patients admitted to Chinese PLA General Hospital from January 2000 to May 2014 were collected(those hospitalized in the department of endocrinology were excluded).A total of 10 041 patients were selected by stratified random sampling.The type of hypoglycemic agents in different departments and the variation on anti-hyperglycemic drugs with time were retrospectively analyzed.Results Of all the patients in non-endocrinological wards, 50.2% were treated with insulin, 36.9% with metformin, 21.3% with α-glycosidase inhibitor, and 18.9% with sulfonylureas.Metformin, α-glucosidase inhibitors, pre-mixed 30R, and insulin glargine were more commonly used than other anti-hyperglycemic agents, accounting for 36.9%, 21.0%, 14.0%, 8.7%, respectively.Metformin, sulfonylureas, α-glucosidase inhibitor, and different types of insulin were more widely applied in internal medicine while insulin therapy was more frequently used in surgical department.During the past 15 years, the proportions of insulin, glinides, α-glucosidase inhibitor, and thiazolidinediones application were gradually increased, while the proportions of sulfonylureas and metformin treatment were on the decline trend.Conclusion Most of the inpatients were treated with oral antidiabetic drugs.Metformin, α-glucosidase inhibitor, pre-mixed 30R, and insulin glargine were the most frequently prescribed agents for the inpatients.

Objective To screen microRNAs(miRNAs)related to early mycosis fungoides(MF). Methods A high?throughput miRNA PCR array was used to determine miRNA expression profiles in skin lesions of 6 patients with early MF (early MF group) and 6 patients with lichen planus (control group), followed by screening of differentially expressed miRNAs between the two groups. Then, real?time fluorescence?based quantitative PCR(RT?qPCR)was performed to verify the differentially expressed miRNAs in lesional specimens from 13 patients with early MF and 13 patients with eczema or lichen planus, as well as in Myla cells and normal human T?lymphocytes. Results The high?throughput miRNA PCR array showed that the expressions of hsa?miR?378a?5p, hsa?miR?107 and hsa?miR?302c?3p were significantly higher in the early MF group than in the control group(all P<0.05). For skin lesions, the results from RT?qPCR were similar to those from the miRNA array assay. Compared with normal human peripheral blood T?lymphocytes, Myla cells showed significantly increased expressions of hsa?miR?378a?5p and hsa?miR?107, which was consistent with the results from the miRNA array assay. However, no significant difference was observed in the expression of hsa?miR?302c?3p between the two kinds of cells. Conclusion MiRNA expression profiles in early MF are different from those in inflammatory skin diseases.

Objective To investigate the diagnosis and differential diagnosis of dermatofibrosarcoma protuberans (DFSP). Methods Totally, 50 patients with DFSP visiting the Institute of Dermatology, Chinese Academy of Medical Sciences from 1998 to 2014 were enrolled. The clinical manifestations, histopathological and immunohistochemical features, treatment and prognosis of DFSP were retrospectively reviewed. Results The average age at onset of DFSP was (29.5 ± 15.9)years in the 50 patients, with a mean disease duration of 9.57 years. Skin lesions most frequently occurred on the trunk(n = 33, 66.0%), followed by the extremities, head and neck. DFSP was characterized by atrophic patches or plaques in 13 cases (26.0%), multiple nodules varying in size and arising on atrophic plaques or patches in 30 cases (60.0%), single or multiple nodules arising on normal skin in 7 cases (14.0%). Histologically, the tumor consisted of uniform infiltrative spindle cells arranged in a storiform or cartwheel pattern. In addition, the tumor cells expressed CD34 and vimentin. Twenty patients experienced recurrence at the primary site after resection of skin lesions with a recurrence rate of 43.5%. No distant metastasis or death occurred in these patients. Conclusions DFSP usually has various skin manifestations, is easily misdiagnosed, and can be confirmed based on histopathological and immunohistochemical findings. Local recurrence of DFSP is common, and may occur for many times after surgical excision, but lymphatic and distant metastases are rare.
