ABSTRACT
Objective:To preliminarily investigate dermoscopic characteristics of trichoblastoma, and to provide ideas for clinical diagnosis of trichoblastoma.Methods:Clinical data were collected from 5 patients with trichoblastoma who underwent both dermoscopic and histopathological examinations in Wuhan No.1 Hospital from November 2018 to July 2021, and dermoscopic features were analyzed retrospectively.Results:According to the presence or absence of pigments, trichoblastoma was divided into 2 subtypes: pigmented trichoblastoma (3 cases) and non-pigmented trichoblastoma (2 cases) . Dermoscopic examination of the 3 cases of pigmented trichoblastoma showed blue-gray ovoid nests (3 cases) , arborizing vessels (2 cases) , blue-gray globules (2 cases) , bright white structureless areas (2 cases) , concentric structures (1 case) and ulcers (1 case) ; no yellow-whitish homogenous structure was found. As for non-pigmented trichoblastoma, dermoscopic features included arborizing vessels (2 cases) , yellow-whitish homogenous structures (2 cases) , bright white structureless areas (2 cases) and blue-gray globules (1 case) ; no ulcers or blue-gray ovoid nests were observed in either case.Conclusion:Dermoscopic patterns differ between pigmented and non-pigmented trichoblastoma, so dermoscopy can provide preliminary diagnostic clues for trichoblastoma.
ABSTRACT
A novel coronavirus pneumonia (NCP) epidemic has occurred in Wuhan, Hubei Province since December 2019, caused by a novel coronavirus (2019-nCoV) never been seen previously in human. China has imposed the strictest quarantine and closed management measures in history to control the spreading of the disease. However, severe trauma can still occur in the NCP patients. In order to standardize the emergency treatment and the infection prevention and control of severe trauma patients with hidden infection, suspected or confirmed infection of 2019-nCoV, Trauma Surgery Branch of Chinese Medical Doctors' Association organized this expert consensus. The consensus illustrated the classification of the NCP patients, severe trauma patients in need of emergency surgery, emergency surgery type, hierarchical protection for medical personnel and treatment places. Meanwhile, the consensus standardized the screening, injury severity evaluation, emergency surgical treatment strategy and postoperative management strategy of severe trauma patients during the epidemic period of NCP, providing a basis for the clinical treatment of such kind of patients.

ABSTRACT
BACKGROUND:In perioperative period of total knee replacement in elderly patients, it is crucial to maintain the normal function of blood coagulation. However, many factors may influence coagulation function of patients in perioperative period. Of them, anesthesia is an important factor. Different anesthesia methods wil produce different effects on blood coagulation. Appropriate anesthesia methods should be selected in the clinic to maintain the stability of coagulation function. OBJECTIVE:To explore the effect of application of general anesthesia and epidural anesthesia in elderly knee replacement and the effects on the function of blood coagulation. METHODS:A retrospective analysis was performed on clinical data of 135 elderly patients after total knee replacement in Dongying Hospital of Shandong Provincial Hospital Group from September 2012 to September 2013. Al patients were divided into control group (67 cases;general anesthesia) and observation group (68 cases;epidural anesthesia) according to the mode of anesthesia. Coagulation indexes and D-dimer levels were observed before anesthesia, 6 hours after anesthesia, and 1 day after replacement in both groups. The incidence of deep venous thrombosis was measured and compared between the two groups in 12-month fol ow-up. RESULTS AND CONCLUSION:Through the statistics and comparison, no significant difference was detected in blood coagulation indexes at different time points in the two groups (al P>0.05). However, significant differences in D-dimer levels were detectable between the two groups at 6 hours after anesthesia and in the morning at 1 day after replacement. D-dimer levels were significantly lower in the observation group than in the control group (al P<0.05). The incidences of deep venous thrombosis were 3%and 21%in the observation and control groups, respectively, showing significant differences (P<0.05). These results suggest that epidural anesthesia during elderly totak knee replacement obtained good effects, and could maintain stable coagulation function.
ABSTRACT
[Summary] Glucose-dependent insulinotropic polypeptide ( GIP) is known to promote the release of insulin fromβcells, but this function suffers from a defect in obese patients. More and more evidences suggest that GIP is the bridge between a high-fat diet, obesity, insulin resistance, and type 2 diabetes. With the deepening of research in GIP in type 2 diabetes and obesity, GIP may provide new ideas for the treatment of type 2 diabetes and obesity.
ABSTRACT
First aid skills are very important in the process of disaster medical rescue methods. Some first aid skills is rarely applied in clinical work at ordinary times, resulting in relevant medical personnel grasp of these skills being not enough skilled. This training method combined with the sim-ulator, has the characteristics and advantages of being close to the real, operational and repeatable. The main training program consists of 6 basic skills such as ventilation, hemostasis, bandaging, fixing, handling, basic life support. By simulating the real disaster scenario and simulation cases, we have targeted a single first aid skills training and multiple comprehensive ability training of first aid skills to trainees. To evaluate the training effect we have examined the individual skills of our trainees, with excellent performance as the goal, and in the comprehensive skills ability assessment we have paid attention to the emergency team's team cooperation ability. By the application of comprehensive simu-lation training and evaluation, the trainees can master all kinds of first aid skills in a short period of time.
ABSTRACT
Objective To enhance the management in identifying the surgical sites to comply with national standards.Methods A nurse-physician collaboration management team was set up to investigate the current identification of surgical sites in every operating room which violates regulations,with the causes analyzed and countermeasures proposed.Working hand in hand,doctors and nurses figured out the management details for preoperatively identifying the surgical sites and reengineering of the surgical process.With the responsibilities clarified and training enhanced,the surgeons,anesthesiologists,ward nurses and operating room nurses were held responsible for the process and improvements of identifying the surgical sites.The number of patients with unreasonable identification of surgical sites was calculated before and after establishment of nurse-physician collaboration management team.Results The reasonable identification rates of surgical sites were 37.94% before the reform and 80.94% after;incorrect use of all types of the surgical site identification can be minimized in the reform.Conclusion The management of nurse-physician collaboration is conducive to enhancing the reasonable identification rate of surgical sites,thus improving the quality of care and correctness of operations.
ABSTRACT
Chronic and heavy alcohol consumption is one of the causes of heart diseases. However, the effects of ethanol on insulin sensitivity in myocardium has been unclear. To investigate the effects of ethanol on the expression of AMP-activated protein kinase (AMPK), myocyte enhancer factor 2 (MEF2) and glucose transporter 4 (GLUT4), all of which are involved in the regulation of insulin sensitivity, in the myocardium, we performed three parts of experiments in vivo and in vitro. I: Rats were injected with 5-amino-4-imidazolecarboxamide ribonucleotide (AICAR, 0.8 mg.kg(-1)) for 2 h. II: Rats received different dose (0.5, 2.5 or 5 g.kg(-1).d(-1)) of ethanol for 22-week. III: Primary neonatal rat cardiomyocytes were isolated and treated with or without 100 mM ethanol or 1 mM AICAR for 4 h. The cardiac protein and mRNA expression of AMPKalpha subunits, MEF2 and GLUT4 were observed by western-blotting and RT-PCR, respectively. Serum TNFalpha levels were assessed by ELISA. The results showed chronic ethanol exposure induced insulin resistance. Ethanol decreased the mRNA levels of AMPKalpha1 and alpha2, the protein levels of total- and phospho-AMPKalpha in cardiomyocytes. Similarly, ethanol showed inhibitory effects on both the mRNA and protein levels of MEF2A and 2D, and GLUT4 in a dose-response-like fashion. Correlation analysis implied an association between phospho-AMPKalpha and MEF2A or MEF2D, and between the levels of MEF2 protein and GLUT4 transcription. In addition, ethanol elevated serum TNFalpha level. Taken together, chronic ethanol exposure decreases the expression of AMPKalpha and MEF2, and is associated with GLUT4 decline in rat myocardium.

Objective To analyze the anesthetic methods and surgical procedures in the treatment of inpatients in N 2 People' s Hospital of Deyang after Wenchuan earthquake. Methods More than 900 patients were sorted for injury triage, among whom 83 patients received emergency surgery within 72 hours after earthquake, and 21 received surgery after 72 hours. After 10 days of the earthquake, the hospitalized patients needing further surgery have been transferred to hospitals in safe regions. Of all patients, 89 (85.58%) were with injuries of extremities, 11 (10.6%) with cerebral trauma, 3 with thoracic injury, and 1 (1.0%) with abdominal trauma. Perioperative noninvasive blood pressure, electrocardiogram, pulse and oxygen saturation were detected during the surgery. All patients were cured except that one patient with traumatic flail chest died 12 hours after the surgery. Results Of all patients undergone surgeries, 35 patients (33.7%) received combined spinal-epidural anesthesia (CSEA), 33 (31.7%) received nerve plexus block (NPB), 5 (4.8%) had CSEA plus NPB, 28 were under general anesthesia (GA) [17 (16.3%) were intubated and 11(10.6%) were non-intubated] and 3 (2.8%) received monitored anesthesia care (MAC). The average ratios of operation time to time for patients stayed in operation room were (51.29±12.38)% in GA group, (53.24±11.39)% in NPB group, (58.43±9.26)% in CSEA group and (77.15±9.27)% in CSEA plus NPB group. There was a significant difference between CSEA + NPB group and the other three groups (P<0.01), and there was no significant difference among GA group, NPB group and CSEA group (P > 0.05). Conclusions During the initial period of rescue, the most common type of injuries are fractures. CSEA plus NPB is encouraged to use as they have the advantages of shorter operation time, higher operation throughput, safety and faster convalescence of the victims.

ABSTRACT
Objective To investigate the effect of cardiopulmonary bypass (CPB) on vascular endothelial cell injury and plasma endothelin-1 and nitric oxide equilibrium in patients undergoing cardiovascular operation with CPB. Methods A total of 20 patients with congenital heart disease (Group Ⅰ) and 20 with valvular problem (group Ⅱ) were operated on under CPB respectively. Blood samples were collected from central vein before skin incision, before CPB, 30 min after CPB, at the end of CPB, and end of operation, the first morning and third morning after operation. The levels of plasma thrombomodulin(TM), endothelin-1(ET-1) and nitric oxide(NO) were measured. Results The plasma TM level was significantly elevated during CPB (P<0.01, P<0.05) and 1 d after operation, reached its peak as (4.88±1.12) ng/ml in Group Ⅰand (8.34±1.84) ng/ml in group Ⅱ at the end of surgery and came back to the level as before operation. The plasma level of ET-1 was also increased significantly after CPB and reached peak as (129.04±22.29) in Group Ⅰ and (156.62±29.66) in Group Ⅱ at the end of operation. And the level was still higher than before operation in 2 groups 3 d after operation. No change was found on the level of NO in 2 groups. Conclusion CPB may cause extensive acute endothelial cells damage for about 24-48 h and recovered about 72 h and it may also cause an imbalance of ET-1 and NO.
