OBJECTS: Sanjoin, the seeds of Zizyphus vulgaris var. spinosus has been used as the most important hypnotic agent in chinese medicine to treat insomnia. This research was performed in order to examine the effect of betulinic acid and sanjoinine-A which are components of Sanjoin. METHOD: Sleeping time, sleep recordings of EEG, serum serotonin level, and locomotor activity were measured in rats which received betulinic acid and sanjoinine-A as sleep induction material extracted from Sanjoin. RESULTS: 1) Groups received betulinic acid, sanjoinine-A, and lorazepam showed increased sleep time than control group with saline. 2) Groups with betulinic acid, sanjoinine-A, lorazepam and saline recorded beta-wave in sleep recording of EEG. In there was no significant difference among all groups. 3) No significant difference in serum serotonin level among all groups was found. 4) In autonomic activity testing, groups of betulinic acid, sanjoinine-A, and lorazepam showed significantly more decreased in activity than saline group. In comparison of groups of betulinic acid and sanjoinine-A with a group of lorazepam, there was no significant difference. CONCLUSION: These results suggests that betulinic acid and sanjoinine-A have the sedative effect like lorazepam rather than sleep effect.

PURPOSE: To analyze serum markers in proximal femur fracture patients, which are known to be accompanied with osteophorosis or metabolic diseases, and consider it as predictive factor and to study how it affects on the fracture form. MATERIALS AND METHODS: Vit. D3 known as serum marker of Vit. D, 25(OH)D, and 1,25(OH)2D of 152 patients from April, 2013 to March, 2014 who visited our hospital and diagnosed as proximal femur fracture(Femur neck fracture 73, Intertrochanteric fracture 79) were analyzed. Also, serum calcium level corrected by serum protein, phosphate, creatinine, alkaline phosphatase, estradiol, IGF-1, and PTH were compared and analyzed. RESULTS: Femur neck fracture group showed significantly low value of D3, 25(OH)D, and 1,25(OH)2D (P-value<0.05) as the values were 37.72+/-7.21 pg/mL, 27.05+/-8.43 ng/mL, 25.05+/-6.78 pg/mL in femur neck fracture group, and 40.36+/-6.97 pg/mL, 29.54+/-9.12 ng/mL, 28.87+/-7.43 pg/mL in intertrochanteric fracture group respectively. The number of patients who were diagnosed as hypovitaminosis D. due to serum 25(OH)D value lower than 30ng/ml were significantly high in femur neck fracture group as the numbers were 56 in femur neck fracture, and 44 in intertrochanteric fracture. Serum calcium level corrected by serum protein, phosphate, creatinine, alkaline phosphatase, estradiol, IGF-1 and PTH level showed no significant difference between two groups. CONCLUSION: Serum 25(OH)D level was decreased in proximal femur fracture patiens, and was lower as the patient was older and BMD was lower. Therefore it is thought that proximal femur fracture is affected by vitamin D metabolism.

Over the past few decades, interest in minimally invasive spine surgery (MISS) has increased tremendously due to its core principle of minimizing approach-related injury while providing outcomes similar to traditional open spine procedures. With technical and technological advancements, MISS has expanded its utility not only to simple spinal stenosis, but also to complex spinal pathologies such as metastasis, trauma, or adult spinal deformity. In this article, we review the techniques and technology in MISS and discuss the indications, benefits, and limitations of MISS.

Objectives: Little is known about the platforms and functionalities of mobile-based personal health record (PHR) applications. The objective of this study was to investigate these two features of PHR systems. Methods: The unit of analysis was general hospitals with more than 100 beds. This study was based on a PHR survey conducted from May 1 to June 30, 2020 and the National Health Insurance administrative data as of March 31, 2020. The study considered the platform, Android and iPhone operation system (iOS), and types of functionalities of PHR systems. Among the 316 target hospitals, 103 hospitals had adopted PHR systems. A logistic regression analysis was used. Results: This study found that 103 hospitals had adopted mobile-based PHR systems for their patients. Sixty-four hospitals (62.1%) were adopting both Android and iOS, but 36 (35.0%) and 3 (2.9%) hospitals were adopting Android only or iOS only, respectively. The PHR systems of hospitals adopting both platforms were more likely to have functions for viewing prescriptions, clinical diagnostic test results, and upcoming appointment status compared to those adopting a single platform (p < 0.001). The number of beds (odds ratio [OR] = 1.004; confidence interval [CI], 1.001–1.007; p = 0.0029) and the number of computed tomography systems (CTs) per 100 beds (OR = 6.350; CI, 1.006–40.084; p = 0.0493) were significantly associated with the adoption of both platforms. Conclusions More than 60% of hospitals had adopted both Android and iOS platforms for their patients in Korea. Hospitals adopting both platforms had additional functionalities and significant association with the number of beds and CTs.

PURPOSE: Pancretojejunostomy leakage is the most dreaded complication after a pancratoduodenectomy. However, little is known about what causes the leakage and how to prevent it. The aim of this study was to dentify the risk factors for pancreatic leakage. This paper describes our experience of its management. METHODS: Between Aug. 1996 and Aug. 2003, 75 consecutive patients with periampullary cancer or benign disease received a pancreatoduodenectomy. The patients' clinical characterisitcs, pathological features and surgical findings were retrospectively evaluated. The patients were classified into those with major complication and rhose with no complications and the risk factors were analyzed. Pancreatic leakage, intraabdomnial fluid collection and abscess, intraabdomnial bleeding were categorized as major complications related to a pancreatic fistula. RESULTS: The postoperative mortality and morbidity rate was 2.6% and 36%, respectively. Univariate analysis showed that the pancreatic texture, pathologic diagnoses and comorbidity were significant risk factors for major complications (P= 0.003, 0.045, 0.02). Multivariate analyses revealed that the, pancreatic texture was the only significant risk factor (P=0.003). The preoperative serum albumin level and pancreatic texture were significant risk factors for pancreatic leakage (p=0.03, 0.025) and multivariate analysis showed that the pancreatic texture was also the most significant risk factor. CONCLUSION: Considering that the pancreatic texture is the most significant risk factor for a pancreatic fistula, the technical skill and experience of the surgeon appears to be important for its prevention.

BACKGROUND: First of all, this study was performed to assess the result of curative radiotherapy and to evaluate different possible prognostic factors for squamous cell carcinoma of the supraglottic larynx treated at the Pusan National University Hospital. The second goal of this study was by comparing our data with those of other study groups, to determine the better treatment policy of supraglottic cancer in future. METHODS AND MATERIALS: Thirty-two patients with squamous cell carcinoma of the supraglottic larynx were treated with radiotherapy at Pusan National University Hospital, from August 1985 to December 1996. Minimum follow-up period was 29 months. Twenty-seven patients (84.4%) were followed up over 5 years. Radiotherapy was delivered with 6 MV photons to the primary laryngeal tumor and regional lymphatics with shrinking field technique. All patients received radiotherapy under conventional fractionated schedule (once a day). Median total tumor dose was 70.2 Gy (range, 55.8 to 75.6 Gy) on primary or gross tumor lesion. Thirteen patients had induction chemotherapy with cisplatin and 5-fluorouracil (1-3 cycles). Patient distribution, according to the different stages, were as follows: stage I, 5/32 (15.6%); stage II, 10/32 (31.3%); stage III, 8/32 (25%); stage IV, 9/32 (28.1%). RESULTS: The 5-year overall survival rate of the whole series (32 patients) was 51.7%. The overall survival rate at 5-years was 80% in stage I, 66.7% in stage II, 42.9% in stage III, 25% in stage IV ( p= 0.0958). The 5-year local control rates after radiotherapy were as follows: stage I, 100%; stage II, 60%; stage III, 62.5%; stage IV, 44.4% ( p=0.233). Overall vocal preservation rates was 65.6%, 100% in stage I, 70% in stage II, 62.5% in stage III, 44.4% in stage IV ( p=0.210). There was no statistical significance in survival and local control rate between neoadjuvant chemotherapy followed by radiotherapy group and radiotherapy alone group. Severe laryngeal edema was found in 2 cases after radiotherapy, emergent tracheostomy was done. Four patients were died from distant metastsis, : three in lung, one in brain. Double primary tumor was found in 2 cases, one in lung (metachronous), another in thyroid (synchronous). Ulcerative lesions were revealed as unfavorable prognostic factor ( p=0.0215), and radiation dose (more or less than 70.2 Gy) was an important factor on survival ( p=0.0302). CONCLUSIONS: The role of radiotherapy in the treatment of supraglottic carcinoma is to improve the survival and to preserve the laryngeal function. Based on our data and other studies, early and moderately advanced supraglottic carcinomas could be successfully treated with either conservative surgery or radiotherapy alone. Both modalities showed similar results in survival and vocal preservation. For the advanced cases, radiotherapy alone is inadequate for curative aim and surgery combined with radiotherapy should be done in operable patients. When patients refuse operation or want to preserve vocal function, or for the patients with inoperable medical conditions, combined chemoradiotherapy (concurrent) or altered fractionated radiotherapy with or without radiosensitizer should be taken into consideration in future.

OBJECTIVE: Detection of focal non-hemorrhagic lesion (NHL) has become more efficient in diffuse axonal injury (DAI) patients using an MRI. The aims of this study are to find out the radiological distribution, progress of NHL and its clinical significance. METHODS: Between September 2005 and October 2011, 32 individuals with NHLs on brain MRI were enrolled. NHLs were classified by brain location into 4 major districts and 13 detailed locations including cortical and subcortical, corpus callosum, deep nuclei and adjacent area, and brainstem. The severity of NHL was scored from grades 1 to 4, according to the number of districts involved. Fourteen patients with NHL were available for MRI follow-up and an investigation of the changes was conducted. RESULTS: Thirty-two patients had 59 NHLs. The most common district of NHL was cortical and subcortical area; 15 patients had 20 NHSs. However the most common specific location was the splenium of the corpus callosum; 14 patients had 14 lesions. The more lesions patients had, the lower the GCS, however, this was not a statistically meaningful difference. On follow-up MRI in 14 patients, out of 24 lesions, 13 NHLs resolved, 5 showed cystic change, and 6 showed atrophic changes. CONCLUSION: NHLs were located most commonly in the splenium and occur frequently in the thalamus and the mesial temporal lobe. Because most NHS occur concomitantly with hemorrhagic lesions, it was difficult to determine their effects on prognosis. Since most NHLs resolve completely, they are probably less significant to prognosis than hemorrhagic lesions.
