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.

To explore the pharmacogenomic markers that affect the platinum-based chemotherapy response in non-small-cell lung carcinoma (NSCLC), we performed a two-cohort of genome-wide association studies (GWAS), including 34 for WES-based and 433 for microarray-based analyses, as well as two independent validation cohorts. After integrating the results of two studies, the genetic variations related to the platinum-based chemotherapy response were further determined by fine-mapping in 838 samples, and their potential functional impact were investigated by eQTL analysis and in vitro cell experiments. We found that a total of 68 variations were significant at P < 1 × 10^-3 in cohort 1 discovery stage, of which 3 SNPs were verified in 262 independent samples. A total of 541 SNPs were significant at P < 1 × 10^-4 in cohort 2 discovery stage, of which 8 SNPs were verified in 347 independent samples. Comparing the validated SNPs in two GWAS, ADCY1 gene was verified in both independent studies. The results of fine-mapping showed that the G allele carriers of ADCY1 rs2280496 and C allele carriers of rs189178649 were more likely to be resistant to platinum-based chemotherapy. In conclusion, our study found that rs2280496 and rs189178649 in ADCY1 gene were associated the sensitivity of platinum-based chemotherapy in NSCLC patients.

Objective:To investigate the clinical characteristics of children with Kawasaki disease (KD) complicated with atlantoaxial rotatory subluxation (AARS).Methods:Clinical characteristics of 60 AARS patients complicated with KD (the atlantoaxial rotatory subluxation group) and 60 patients with KD only diagnosed (the control group)in the Children′s Hospital of Chongqing Medical University from December 2010 to December 2019 were retrospectively analyzed.Differences between groups were compared by the Chi- square test and the t test. Results:A total of 8 365 KD patients were diagnosed during the study period, involving 60 cases (0.72%) complicated with AARS.which usually occurred in the acute phase with the onset ages of 3 to 6 years ( P<0.001). Initial clinical symptoms of KD complicated with AARS included fever with restricted neck movement (100.00%), neck mass (66.67%), torticollis (21.67%) and neck pain (11.67%). CT or X-ray exa-mination of the neck indicated AARS, with thickening and swelling of the cervical soft tissues in some cases.Compared with those of control group, red, dry, cracked lips ( P=0.01) and cervical lymph node swollen ( P<0.001) were significantly pronounced in KD patients complicated with AARS.The absolute and relative count of neutrophils were significantly higher in KD patients complicated with AARS (all P< 0.05). Cervical soft tissue swelling and thickening in B-ultrasound were more obvious than those in the control group( P<0.05). However, there were no significant differences in coronary artery lesions and the response to intravenous immunoglobulin (IVIG) combined with Aspirin between groups ( P>0.05). Head traction could relieve neck symptoms to a certain extent, but there was no significant difference between groups ( P>0.05). Conclusions:Cervical lymphadenopathy, red, dry, cracked lips, increase of absolute and relative count of neutrophils, and swelling and thicke-ning of cervical soft tissues were the high-risk factors of KD complicated with AARS.The complication of AARS in KD patients did not increase the risk of coronary artery injury and IVIG resistance.IVIG combined with aspirin achieved a good prognosis in the majority of KD patients complicated with AARS.

As an important carrier of cultivating people with virtue, curriculum aesthetic education combines aesthetic education with professional courses and general courses, and brings it into the whole process of professional talent cultivation. As the core course of medical humanistic education, Medical Ethics not only has natural affinity with aesthetic education, but also has the functions of emotional aesthetic education, rational aesthetic education and human aesthetic education. Through the analysis of aesthetic education points in Medical Ethics, this paper put forward the implementation path to realize the function of the curriculum aesthetic education: exert aesthetic influence on medical students with the help of aesthetic media, guide medical students’ aesthetic attitude, and then make medical students learn to feel, appreciate beauty through practice and sharing ideas, before or after class, online or offline, so as to contribute to the cultivation of high-quality medical talents with lofty aesthetic pursuit and noble-personality cultivation.

Objective:To investigate the anticoagulant causes, hemorrhagic susceptibility factors and clinical characteristics of patients with warfarin-related major bleeding in the emergency department of a general hospital.Methods:In a registry study from January 2017 to February 2020, 114 cases of warfarin-related major bleeding patients admitted to Department of Emergency Medicine, the First Affiliated Hospital of Wenzhou Medical University were enrolled. The descriptive methods were used to analyze anticoagulant causes, hemorrhagic susceptibility factors and clinical characteristics. Patients were divided into the international normalized ratio (INR) overrange group and the INR non-overrange group according to INR value during bleeding. The Chi-square test, Student’s t test, and Wilcoxon rank sum test were used to compare the differences between the INR overrange group and the INR non-overrange group. The Wilcoxon rank sum test and Student’s t test were used to analyze the characteristics of gastrointestinal tract bleeding and cerebral hemorrhage. Results:Warfarin-related major bleeding accounted for 0.36% (114/32 040) of first aid cases and 9.84% (114/1 158) of warfarin-taking cases, respectively. Seventy-seven cases (67.5%) of anticoagulant causes were related to atrial fibrillation (AF) and 32 cases (28.1%) were related to post-operative cardiac valve replacement. Of the bleeding susceptibility factors, HAS-BLED scored at 4.0 (3.0, 5.0), 84 cases (73.7%) had a history of drug use, 77 cases (67.5%) aged older than 65 years old, 65 cases (57.0%) had irregular INR monitoring, and 29 cases (25.4%) had recent increase in dose. Forty cases (35.1%) were gastrointestinal tract bleeding with the lowest hemoglobin (Hb) value and the highest score of HAS-BLED. Twenty-one cases (18.4%) were cerebral hemorrhage with the shortest prothrombin time (PT), the lowest INR value, the highest Hb, and the lowest score of HAS-BLED. Twelve cases (10.5%) died or gave up treatment in critical condition, including 6 cases of cerebral hemorrhage, 5 cases of gastrointestinal tract bleeding, and 1 case of hemoptysis. There were statistically significant differences in previous history of antiplatelet therapy, recent increase in dose, HAS-BLED score and bleeding site between the INR overrange group and the INR non-overrange group (all P<0.05). Conclusions:Among patients with warfarin-related major bleeding, AF and post-operative cardiac valve replacement are the main causes of warfarin anticoagulation. INR overrange is related to the previous history of antiplatelet therapy, recent increase in dose, and the high score of HAS-BLED. The gastrointestinal tract bleeding is the most common, with the lowest Hb value and the highest score of HAS-BLED. Cerebral hemorrhage is the second common, with the shortest PT, the lowest INR value, and the highest Hb. The incidence and mortality rates of warfarin-related major bleeding are relatively high.

Antipsychotic-induced weight gain (AIWG) is a common adverse effect of this treatment, particularly with second-generation antipsychotics, and it is a major health problem around the world. We aimed to review the progress of pharmacogenetic studies on AIWG in the Chinese population to compare the results for Chinese with other ethnic populations, identify the limitations and problems of current studies, and provide future research directions in China. Both English and Chinese electronic databases were searched to identify eligible studies. We determined that > 25 single-nucleotide polymorphisms in 19 genes have been investigated in association with AIWG in Chinese patients over the past few decades. HTR2C rs3813929 is the most frequently studied single-nucleotide polymorphism, and it seems to be the most strongly associated with AIWG in the Chinese population. However, many genes that have been reported to be associated with AIWG in other ethnic populations have not been included in Chinese studies. To explain the pharmacogenetic reasons for AIWG in the Chinese population, genome-wide association studies and multiple-center, standard, unified, and large samples are needed.

Objective: To analyze the effect to the prognosis of tumor site on the patients of colorectal cancer after curative resection with different stage. Methods: Clinicopathological and follow-up data of 2 097 colorectal carcinoma cases undergoing resection at Fourth Hospital of Hebei Medical University from January 2008 to March 2015 were retrospectively analyzed. There were 421 patients in left-sided colorectal cancer (LCC) group (including carcinoma in cecum, ascending colon , hepatic flexure, and transvers colon) , 386 in right-sided colorectal cancer (RCC) group (including carcinoma in splenic flexure, descending colon and sigmoid colon) and 1 290 in rectal cancer (RECC) group. Clinicopathologic features in patients with different tumor location were compared. 5-year overall survival rate were compared among the 3 groups. Patients were stratified by different stage to analyze the effect of tumor location on the prognosis. χ²test and Kruskal-Wallis rank-sum test were used to compare the clinicopathological features among the 3 groups, Kaplan-Meier curve and Log-rank test were used to analyze prognosis, respectively. Results: No significant differences were identified between the three groups in age, family history, N stage and intestinal obstruction. Significant difference were found in gender among LCC, RCC and RECC group (male were 62.5% vs. 54.9% vs.56.3%, χ²=6.040, P=0.049) . Compared with LCC group and RCC group, RECC group had more well and moderately differentiated adenocarcinoma patients (89.7% vs. 86.0% vs. 82.4%, χ²=10.712 and 17.385, P=0.013 and 0.001) , more stage Ⅰ patients (17.1% vs. 6.9% vs. 6.5%, χ²=37.459 and 37.208, P=0.000 and 0.000) , and less likely to be stage T4 (44.7% vs. 76.7% vs.78.5%, χ²=128.015 and 133.704, P=0.000 and 0.000), metastasis (2.6% vs. 5.7% vs. 3.6%, χ²=1 417.167 and 1 424.217, P=0.000 and 0.000) and intestinal obstruction (11.3% vs. 21.1% vs. 24.4%, χ²=25.846 and 41.141, P=0.000 and 0.000). Five-year survival rate reduced in turn in the patients with RECC, LCC and RCC(70.9%, 59.8%, 58.9%, χ²=11.577, P=0.009). In the subgroup of stage Ⅲ, patients with different tumor location had different overall survival (χ²=9.878, P=0.007). Compared to right-sided colon cancer patients, rectal ones had significantly better overall survival (χ²=9.271, P=0.002); but in the subgroup of stage Ⅰ, Ⅱ and stage Ⅳ, patients with different tumor location had similar overall survival (P were 0.124, 0.888, 0.263, respectively). Conclusions Colorectal cancer patients with tumor location had different clinicopathologic features. Patients with rectal cancer had better five-year survival rate than those with left located and right located colon cancer. Tumor location had different effects on the prognosis according to the different TNM stage-subgroups.

AIM:To observe the expression of tyrosine hydroxylase (TH), ionized calcium binding adapter molecule 1 (Iba1) and pro-opiomelanocortin (POMC) in rat arcuate nucleus (Arc) of hypothalamus induced by substantia nigra (SN) lesion with 6-hydroxydopamine (6-OHDA).METHODS:According to the random number table, 20 SD rats were randomly divided into 6-OHDA group and control group.6-OHDA was injected into the bilateral SN of the rats in 6-OHDA group, and the same volume of saline was injected into the same position of the rats in control group.After 6 weeks, the rats were sacrificed and the brains were obtained.Immunofluorescence staining and Western blot were used to detect TH expression in the SN, and TH, Iba1 and POMC expression in the Arc.RESULTS:Compared with control group, no significant change of body weight in 6-OHDA group was observed, but the weight of retroperitoneal fat decreased from (7.550±0.670) g to (3.895±0.465) g (P<0.01).The number of TH immunoreactive neurons in SN decreased from 56±5 to 14±2 (P<0.05), and the TH protein level decreased from 0.75±0.11 to 0.41±0.09 (P<0.01).In the Arc, the number of TH immunoreactive neurons decreased from 21±2 to 10±3 (P<0.05), the number of Iba1 immunoreactive neurons increased from 12±2 to 30±5 (P<0.05), and the number of POMC immunoreactive neurons increased from 16±4 to 31±2 (P<0.05).In the hypothalamus, the TH protein level decreased from 0.35±0.05 to 0.21±0.02 (P<0.01), the Iba1 protein level increased from 0.23±0.06 to 0.51±0.04 (P<0.01), and the POMC protein level increased from 0.37±0.05 to 0.65±0.03 (P<0.01).CONCLUSION:The changes of TH, Iba1 and POMC expression in Arc of 6-OHDA-treated rats may involved in the fat loss in Parkinson's disease.
