Objective To investigate the expression of glucose transporter 3(GLUT 3) transcription level at different ischemic time in rats' focal cerebral ischemic penumbra and core of cortices.Methods Focal ischemic models of middle cerebral artery occlusion (MCAO) in rats were made by inserting nylon surgical thread. Brain samples were harvested from ischemic penumbra and core of cortices. The change of GLUT 3 mRNA was assessed by RT PCR.Results GLUT 3 mRNA in the penumbra regions slightly increased at 3 h after ischemia, and reached a peak at 24 h, in 96h following ischemia it came back to the normal level. As for ischemic core regions, GLUT 3 mRNA had a short time increase at 3 h after ischemia, and then rapidly decrease to the low level. Conclusion GLUT 3 mRNA expression was notably up regulated in the penumbra regions after focal cerebral ischemia,it may be a protective reaction against ischemic injury.

Objective To evaluate the clinic effects of perioperative psychological intervention combined appropriate sedation by target-controlled infusion of midazolam during operation via symptom check List 90 (SCL-90) and observers assessment of alertness/sedation scale (OAA/S) in patients undergoing thumb or finger reconstruction.Methods Eighty patients undergoing thumb or finger reconstruction were randomly divided into group A,B,C,and D (n =20 cases per group).All patients were received brachial plexus block and spinal-epidural combined anesthesia.Patients in group A were given perioperative psychological intervention combined appropriate sedation by target-controlled infusion of midazolam during operation; patients in group B were received routine treatment; patients in group C were given perioperative psychological intervention; and patients in group D were sedated with midazolam during operation.The vital signs and the scores of OAA/S were observed during operation.The scores of visual analogue scale (VAS) and SCL-90 were recorded after operation.Results The OAA/S grade in groups A and D were stability than that in groups B and C (P ＜ 0.05) ; the scores of VAS and the results of psychological status assessment by SCL-90 in group A were superior to groups B,C,and D (P ＜ 0.05).Conclusions Perioperative psychological intervention combined appropriate sedation in operation on thumb or finger reconstruction is a excellence anaesthesia processing method.It might have beneficial effects on postoperative recovery profile,and strengthen the tolerance to pain and improve the patient's psychological status during operative period.

Objective To evaluate subclavicular angiography with brachial-axillary artery externally and temporally occluded in depicting hemoptysis-related ectopic arteries originating from shoulder, neck and chest wall in the interventional treatment of hemoptysis. Methods A retrospective analysis of the medical records and angiograms of 103 patients who underwent transarterial procedures for hemoptysis was carried out. The arteries originating from the subclavicular arteries supplying the shoulder, the neck and the chest wall, ectopic bronchial arteries (EBA) as well as non bronchial systemic arteries (NBSA), were depicted by subclavicular angiography with brachial-axillary artery externally and temporally occluded. The number and distribution of the responsible aberrant arteries were investigated. Results Of the hemoptysis-related arteries(n=372) depicted and embolized in the studies, 51.9% was normally-originated bronchial arteries(n=193),6.7% was ectopic bronchial arteries (n=25),41.4% was NBSA(n=154).Both anomalous and NBSA arising from subclavicular-axillary area(n=80) were accounted for 21.5% (80/372) of all aberrant arteries, and 44.7%(80/179) of all anomalous and NBSA (n=25+154=179).Of those arising from subclavicular-axillary arteries,56.3%(45/80) were found to be originated from the internal thoracic artery (n=45),98.2%(112/114)of responsible internal thoracic arteries and their distal branches were well depicted by subclavicular angiography with brachial-axillary artery externally and temporally occluded. Conclusion Subclavicular-axillary artery is a very important vessel where EBA and NBSA originate. Subclavicular angiography with brachial-axillary artery externally and temporally occluded could help to determine the abnormal arteries in the region quickly. The method should be taken as a routine procedure for interventional treatment of hemoptysis.

Objective: To investigate whether insulin stimulates the translocation of glucose transporter-4 (GLUT4) and glucose uptak e in ischemic myocardium. Methods: Plasma concentration of gluc ose, lactate, free fatty acid and insulin were determined by autoanalyser, and G LUT4 was studied by Western blotting analysis. Results: Insulin increased GLUT4 significantly in sarcolemma of ischemic myocardium ［(25±4)% vs (40±6)%］, and GLUT4 content in intracellular membrane decreased proporti onally. The glucose uptake increased significantly in insulin-ischemic myocardi um. The uptake of insulin-ischemic myocardium was almost 2 times that of ischem ic myocardium. Conclusion: Insulin stimulation results in GLUT4 translocation and increases glucose uptake in ischemic myocardium. When myocardi al ischemia occurs, insulin is helpful in increasing myocardial glucose uptake a nd utilization.

Purpose To explore the CT manifestations and pathological features of pneumonia-type lung cancer, and to improve the diagnosis capability of pneumonia-type lung cancer. Materials and Methods CT and pathologic features of 33 cases of biopsy or surgical pathology confirmed pneumonia-type lung cancer patients were retrospectively analyzed and classified according to the new pulmonary adenocarcinoma classification. Results Among the 33 pneumonia-type lung cancer subjects, CT showed multiple distributions within both lungs in 22 cases, lateral lobe distribution in 9 cases, segmental distribution in 2 cases. Lung consolidation was found in all lesions, among them 21 cases appeared mainly as lower lobe consolidation, 32 cases as inflatable bronchial symptoms within the consolidation, including inflatable bronchoconstriction in 24 cases;consolidation with multiple pulmonary nodules found in 23 cases;ground glass shadowing around or distal to the consolidation found in 26 cases;combined with cysts or honeycomb lung symptom in 13 cases. Inhomogeneous mild enhancement of lung consolidation after enhancement found in 18 cases and inhomogeneous moderate enhancement in 15 cases;blood vessel branch shadow within the consolidation was visible in 21 cases. Pathology results revealed 26 cases of invasive mucinous adenocarcinoma, and 7 cases of invasive mucinous adenocarcinoma partial mixed with papillary or alveolar adenocarcinoma. Conclusion CT features of pneumonia-type lung cancer are single or multiple opacities, within which inflatable bronchial symptoms can be observed, with multiple nodules and ground glass shadowing, cysts or honeycomb symptom can also be found concomitant, the lesions expand, increase and spread to both lungs, taking its dynamic change features into consideration will also help to improve the diagnostic accuracy.

[ABSTRACT]OBJECTIVETo study of the relationship of age and climate with the nasal mucosa lesions.METHODSAll the patients met with the inclusive criteria were registered and followed-up once a month and their nasal mucosal lesions were observed through nasal speculum and/or nasal endoscope. The recording data was analyzed by SPSS17.0 software.RESULTSA total of 259 patients, 555 person-times and 957 lesion spots were observed. The nasal mucosa was injured by airflow with the highest incidence rate from October to next year April. Patients numbers gradually increased after August, and significantly increased at November, December (P<0.05). Children aged from 2 to 12 years old and the adults aged from 40 to 80 years old were susceptible population (P<0.05), the incidence rate had a negative relation with humidity (P<0.05). The susceptible spots of the lesion were ranked as follows: Little area, inferior turbinate, mucosa of the both side of the deviated nasal septum, inferior meatus, middle meatus, middle turbinate and olfactory area. CONCLUSIONNasal mucosal injury relates to age and seasons. The nasal cavity airflow may be a factor of these lesions.

Objective:To explore the clinical efficacy of double opposing rhomboid flap in repairing facial skin defects.Methods:From January 2020 to December 2020, 30 cases of facial skin lesions were removed in the Department of Plastic and Aesthetic Surgery, the Affiliated Hospital of Qingdao University, including 12 males and 18 females, aged 14-65 years, with an average age of 34.2 years. The diameter of the facial skin defect wound was 0.5-2.0 cm. The patients with facial skin defect were repaired with double opposing rhomboid flap. All patients were followed up for 3-12 months.Results:The incisions of 30 patients were healed in one stage, and double opposing rhomboid flaps survived. Following-up for 3 to 12 months showed that the operation area was flat, the incision scar was not obvious, the texture and color of the operation area and the surrounding skin matched well, the surrounding organs were not deformed, the lesions were not recurrent, and the cosmetic effect was satisfactory.Conclusions:The double opposing rhomboid flap is an effective method to repair quasi-circular facial skin defects, which is worthy of clinical application.

Objective:To compare the postoperative effects of double eyelid surgery with different exophthalmos to find its influence on the surgery and necessary changes in preoperative design and during operation.Methods:A total of 50 female patients with single eyelid seeking beauty from June 2021 to March 2022 were selected from the Department of Plastic Surgery, Affiliated Hospital of Qingdao University. The ocular protrusion was measured by HETEL ophthalmostatometer before surgery. Both eyes at 12-15 mm were taken as normal group ( n=26), both eyes at 16-18 mm as mild protrusion group ( n=14) and both eyes at 19-22 mm as severe protrusion group ( n=10). All the patients were treated with double-eyelid surgery by orbital septum and unified postoperative nursing. Results:After six months of follow-up, there was no difference in eyelid width with closed eyes (all P>0.05). The width of double eyelid with open eyes in normal group was smaller than that in mild protrusion group ( F=23.23, all P<0.05), and the width of double eyelid with open eyes in mild protrusion group was smaller than that in severe protrusion group ( F=47.70, all P<0.05). There was no difference in the improvement rate of facial aesthetics among the three groups ( P>0.05). The " feeling of meet" and scar formation in the normal group were less than those in the mild protrusion group ( F=16.92, F=33.45, all P<0.05), and the " feeling of meet" and scar formation in the mild protrusion group were less than those in the severe protrusion group ( F=27.93, F=28.53, all P<0.05). The improvement rate of normal group was higher than that of mild and severe protrusion group (χ 2=7.25, 7.89, all P<0.05). There was no difference in the improvement rate between the mild and severe protrusion groups ( P>0.05). Conclusions:In clinical practice, it is necessary to make corresponding changes in the preoperative design and operation of double eyelid surgery for patients with high eyeball protrusion.
