OBJECTIVE: To investigate the expression of SOX2 in laryngeal carcinoma and analyze the relation of SOX2 and clinical factors. METHOD: We measured the expression of SOX2 protein in 45 laryngeal carcinoma fresh samples and 45 paracarcinoma tissues (cutting margin > 0.5 cm) with flow cytometer (Epics-XL II), 20 normal laryngeal mucosa samples were also studied as controls. RESULT: The quantitative and qualitative expression of SOX2 protein in laryngeal carcinoma tissues was obviously higher than those in paracarcinoma and in normal laryngeal mucosa tissues respectively (P < 0 05). There was no significant difference between the expression of paracarcinoma and normal laryngeal mucosa tissues. In laryngeal carcinoma, the expression of SOX2 protein wasn't significantly related to patients' clinical classification, tumor size, smoking history, patients' age and sex but related to metastasis, pathological grade and clinical stage. CONCLUSION The high expression of SOX2 may contribute to the carcinogenesis and development of laryngeal carcinoma. It is an important index of judging metastasis and staging and prognosis of laryngeal carcinoma to measure the expression of SOX2 protein.

Objective To explore the feasibility of using short-latency somatosensory evoked potentials (SLSEP) to quantitate Deqi.Methods A randomized crossover controlled trial was carried out. Healthy subjects were enrolled and allocated to treatment (thick needle, deep insertion and manipulation for Deqi) and control (thin needle, shallow insertion and no manipulation without Deqi) groups. Somatosensory evoked potentials were recorded before, during and after acupuncture. Deqi was assessed using the score scale in the subjets. The effects of Deqi and no Deqi at point Sanyinjiao (SP 6) on the potentials were observed.Results The preliminary exploration of the feasibility by the trial test showed that the effect of Deqi on short-latency somatosensory evoked potentials had certain regularity. It was worthy to be observed.Conclusion The plan is feasible. The formal test can be conducted.

Objective By using infrared thermal imager (Flir-SC620), to observe the effect of needling Sanyinjiao (SP6) on the skin temperature at Guanyuan (CV4) and Sanyinjiao in patients with primary dysmenorrhea (PD) of cold and dampness stagnation pattern, and to explore the probability of using infrared thermal imaging for diagnosis and as an objective index for evaluating the action and needling qi of acupuncture. Method Thirty-six subjects were recruited and divided into four group, a health control group (group A), a control group of PD of cold and dampness stagnation pattern (group B), a needling-qi-expected group (group C) and a needling-qi-unexpected group (group D). Group A and B were not given acupuncture treatment, while group C and D were treated with acupuncture at bilateral Sanyinjiao with needles retained for 30 min, and the needling sensations were recorded. The infrared thermal imager was used to detect the skin temperature at Guanyuan and bilateral Sanyinjiao for 40 min for each group, and the temperature was recorded every 10 min. The temperature during different periods of time, 0-10 min, 20-20 min, 20-30 min, 30-40 min, 0-30 min, and 0-40 min were then calculated. In group C, those obtained the needling qi sensation were further grouped into C-1 and those didn’t obtain the sensation were into C-2; in group D, those obtained needling qi sensation were further grouped into D-1 and those didn’t obtain the sensation were into D-2. SPSS 17.0 was adopted for data processing, and the data were analyzed by using MANOVA of repeated measuring. Result Compared to group A (6 cases), the temperature at Guanyuan in group B (6 cases) was significantly decreased during 0-30 min and 0-40 min (P<0.05), the temperature at the left Sanyinjiao during 0-40 min in group B was significantly decreased (P<0.05), and the temperatures at bilateral Sanyinjiao during 30-40 min in group B significantly dropped (P<0.05). Compared to group B, the temperatures at Guanyuan during 0-30 min and 0-40 min in group C1 (12 cases) and group D1 (11 cases) were significantly increased (P<0.05), the temperature at left Sanyinjiao during 0-40 min in group D1 was significantly increased (P<0.05), and the temperatures at bilateral Sanyinjiao during 30-40 min in group D1 were significantly increased (P<0.05). There was no case in group C2 and only 1 case in group D2, hence, the data were not enough for analysis. Conclusion Decrease of the infrared temperature at Guanyuan and Sanyinjiao can be taken as one of the diagnostic criteria for dysmenorrhea of cold stagnation pattern. Increase of the infrared temperature at Guanyuan can be regarded as one of the objective evidences for the along-meridian transmission characteristic in needling Sanyinjiao.

Objective:To investigate whether intestinal rehabilitation therapy (IRT)could optimize the effectiveness of IRT in patients with short bowel syndrome (SBS) caused by acute mesenteric ischemia (AMI) with chronic multivessel lesions.Methods:Clinical data of 18 hospitalized patients diagnosed with AMI leading to SBS and undergoing IRT at the Eastern Theater General Hospital of the People's Liberation Army from Jan 2012 to Oct 2023 was retrospectively analyzed.Result:Following IRT, the revascularization group showed significantly greater increases in ASMI and grip strength compared to the control group [(0.28±0.26) kg/m 2vs. (0.02±0.21) kg/m 2, P=0.033, and (0.97±0.33) kg vs. (0.48±0.34) kg, P=0.007, respectively]. Similarly, the increase in EN intake was significantly higher in the revascularization group compared to the control group [(572.5±93.6) ml/d vs. (375.2±176.3) ml/d, P=0.012], accompanied by a greater improvement in intestinal nitrogen absorption rate [(25.06±14.06)% vs. (13.84±4.62)%, P=0.034] and a more substantial decrease in GSRS scores [(-15.88±3.94) vs. (-6.33±5.13), P=0.030]. Moreover, there were significant differences in the composition of EN formulations between the two groups after IRT ( P=0.046). Additionally, SF-36 scores at discharge were significantly higher in the revascularization group than that in the control group for five indicators including BP, GH, VT, SF, and MH ( P<0.05). Conclusions:For patients with SBS resulting from AMI by chronic multivessel lesions, revascularization therapy may not leading to higher growth in weight and hematological nutritional indicators during IRT, but it is beneficial for improving muscle function, improving EN absorption, increasing the likelihood of PN independence, relieving gastrointestinal symptoms, and enhancing overall quality of life.

PURPOSE: Pralidoxime(2-PAM) is the mainstay of organophosphate intoxication management as an antidote. We investigated the usefulness of high-dose pralidoxime therapy. METHODS: From January 2000 to July 2003, 86 patients presented with organophosphate insecticide intoxication to the emergency medical center of Chonnam National University Hospital. They were randomized into two groups: Group I was given continuous IV infusion of pralidoxime in dose of 500 mg/hr after an initial bolus dose of 2 g and Group II was given continuous IV infusion of pralidoxime in dose of 1000 mg/hr after an initial bolus dose of 2 g. Both groups were given same therapeutic interventions, including the duration of atropine administration. The plasma cholinesterase activites were monitored at admission and at 24 hr and 48 hr after infusion of pralidoxime. The effectiveness of the two treatment modalities were gauged by comparing the durations of mechanical ventilation and intensive care unit (ICU) stay. RESULTS: The mean durations of mechanical ventilation were 9.82+/-6.45 days in group I and 6.51+/-4.50 days in group II. The mean durations of ICU stay were 12.82+/- 7.69 days in group I and 9.15+/-5.38 days in group II. group I showed that longer durations of mechanical ventilation (p=0.03) and ICU stay( p<0.001). The plasma cholinesterase reactivation rate were higher in group II than in group I. CONCLUSION: The results suggest that continuous high-dose pralidoxime therapy may be helpful in the treatment of organophosphate intoxication.

PURPOSE: As Gwangju Wide Regional Emergency Medical Center was newly opened during February 2001, a comparative analysis was performed of patients who had visited the emergency department before and after the opening in order to measure the difference and to provide basic data for its management. METHODS: The 9,995 patients who had visited between February 1, 1999, and July 31, 1999, before the opening and the 12,457 patients who visited between February 1, 2001, and July 31, 2001, after its opening were compared according to sex, age, non-trauma or trauma, means and form of visit, attending department, length of stay in the emergency department, form of discharge, and time of death verification (dead-on-arrival (D.O.A) versus deadafter-arrival (D.A.A)). RESULTS: The total number of patients increased by 24%. The admission rate was 31.8% before the opening and 40.6% after the opening; the mean length of stay in the emergency department was 15.7 hours before the opening and 12.2 hours after the opening. The mean length of stay of admitted patients decreased from 26.6 hours before the opening to 18.3 hours after the opening. CONCLUSION: The decrease in the mean length of stay in the emergency department from 15.7 hours before the opening to 12.2 hours after the opening is viewed as a positive result, but is still not satisfactory. Accordingly, it is considered urgent that every clinical department take an active part in improving circulation of patients both in the Emergency Intensive Care Unit (EICU) on the second floor and in the emergency ward on the fifth floor, as well as in providing rapid medical care and decisions on treatment strategies in the emergency department on the first floor.

PURPOSE: Hyponatremia is the most common electrolyte imbalance encountered in the hospital, there have been few studies about the clinical characteristics of hyponatremia in emergency patients. This study was performed to evaluate the causes and the initial symptoms of hyponatremia in emergency patients, the relationship between their ages and their initial symptoms and the relationship between the causes and the recovery time. METHODS: A total of 42 patients with hyponatremia, who were treated in the Emergency Department of Chonnam National University Hospital from 2000 to 2001, were studied by chart review. RESULTS: The initial symptoms were generalized weakness (33.3%), seizure (28.6%), mental change (21.6%), confusion (9.5%), dizziness (4.8%), and non-specific (2.4%). There was a significant difference in the initial symptoms between children and older. The initial symptom for younger patients was usually seizure. The most common causes of hyponatremia were dehydration and sodium loss (52.4%), other causes were hypothyroidism (11.9%), SIADH (7.1%), heart failure (7.1%), adrenal insufficiency (4.8%), polydypsia (4.8%), CRF (2.4%), nephrotic syndrome (2.4%) and unidentified causes (7.1%). There were significant differences in the recovery times among the causes of hyponatremia. CONCLUSION: The initial symptoms of hyponatremia in emergency patients were usually generalized weakness in older patients and seizure in the young. There were significant differences in the recovery times among the causes of hyponatremia. There were many more incidences of hypovolemic hyponatremia of emergency patients than normovolemic hyponatremia.

PURPOSE: Serum aspartate aminotransferase (AST) is an enzyme widly used in the diagnosis of acute liver disease. It is also highly sensitive in cases of myocardial infarction and muscular injury. This study is designed to ascertain the utility of AST for diagnosis in emergency room. METHODS: From July 2001 to September 2002, 98 patients with AST greater than ten times (400 U/L) the normal range were identified by the biochemistry laboratory in the Emergency Medical Center of Chonnam National University Hospital. The patients 'clinical records were studied to determine the diagnosis, the clinical course, the physical finding on arrival, the past history, other serological and imaging studies, etc. RESULTS: The most common cause of elevated AST level was hepatic in origin (74 cases, 75.5%). Other causes were soft tissue injury (13 cases, 13.3%) and myocardial infarction (11 cases, 11.2%). In group with hepatic causes for raised AST, 21 (28.3%) patients had pancreaticobiliary desease, 20 (27.0%) patients were in conditions producing hepatic ischemia, 18 (24.3%) patients had hepatocellular desease, 6 (8.1%) patients had traumatic liver injury, and 4 (5.4%) patients had malignancy. The hepatic ischemia was caused by sepsis (6 cases, 30.0%), heart failure (6 cases, 30.0%), hypoxia (5 cases, 25.0%), and prolonged hypotension (3 cases, 15.0%). CONCLUSION: The main cause of a notably increased serum AST level is known to be hepatocellular disease, but this study for emergency patients revealed that other causes, such as hepatic ischemia, traumatic liver injury, and muscular disease, were also remarkable. When the level of serum AST is abnormally high, the clinician must consider not only hepatocellular disease but also prolonged hypotension, circulatory collapse, hypoxia, traumatic liver injury, etc.

Hydatid disease is a parasitic infection caused by the Echinococcal species. Humans are intermediate hosts and become infected directly by contact with canines or indirectly by contact with food, water, and contaminated objects. This disease involves multiple organs, including liver, lung, heart, muscle, bone, kidney, and brain. Rupture of a hydatid cyst, which is the most common complication of this disease, can cause serious sequelae, including allergic reaction, secondary infection, biliary obstruction, and metastasis. The hydatid disease occurs principally in areas of cattle and sheep ranching. In Korea, this disease is rare, and only a few cases have been reported. We report a case of hydatid disease with anaphylactic shock and suggest that hydatid cyst complications must be kept in mind when dealing with patients who have a history associated with an endemic region.

Risk factors for infective endocarditis include injection drug abusers and patients with structural heart defects undergoing dental procedures. Infective endocarditis is clinically important because it is hard to diagnose it in its early stage owing to its various clinical manifestations, and because its morbidity and mortality increase when neurologic complications occur. This is a case of infective endocarditis in the course of treatment of which complicating cerebral hemorrhage and infarction progressed rapidly and prompted death.
