Objective To observe and evaluate the clinical effects of thymosin ?1 on gastrointestinal carcinoma in elderly patients.Methods Ninety-six aged patients with gastrointestinal carcinoma in the General Hospital of PLA,who had received chemotherapy,were randomly divided into two groups(n=48 for each group): control group and treatment group.Patients in the treatment group received thymosin ?1 by subcutaneous injection in a dose of 1.6mg,the treatment was given once every other day and the whole course lasted for 8 weeks;while patients in the control group received physiological saline solution in the same amount only instead of thymosin.For the patients in both groups,the activities of peripheral blood T cell subsets,such as CD4+,CD4+/CD8+ and natural killer(NK),were measured by flow cytometry before the treatment and in the 2nd,4th,8th week of chemotherapy.The life quality of every patient was evaluated by Karnofsky scores at the same time.Results After the treatment,the Karnofsky scores in the treatment group were much higher than that in the control group(P

The necessity to carry out student-oriented teaching of Medical information retrieval and use course in medical postgraduate was analyzed according to its theory followed by an elaboration on its module setting, course management methods, course examination forms and teachers.

Even though closed treatment of Colles' fracture leads to satisfactory clinical results, many patients who have had such a fracture are found to have permanent disability and poor function of hand and wrist. Malunion occurs frequently following Colles' fracture and there is considerable disability, pain and deformity associated with this lesion. Such deformity of wrist can usually be prevented by proper treatment, but if deformity developes, better function and a normal appearing wrist can be restored by a corrective osteotomy. The authors experienced 6 cases of malunited Colles' fracture which had been treated by corrective osteotomy, Darrach resection, and osteoclasis, etc.

Objective To study the clinical discrepancy between patients with post infectious irritable bowel syndrome(PI-IBS) and non post infectious irritable bowel syndrome(NPI-IBS),and assess the value of serum intestinal fatty acid binding protein (I-FABP) for differential diagnosis.Methods A total of 117 patients with PI-IBS,201 patients with NPI-IBS and 31 healthy controls were prospectively recruited in General Liberation Army Hospital from 2010 to 2013.Plasma samples and clinical data were collected.Serum I-FABP level was measured by an enzyme-linked immunosorbent assay.Results The median age of patients with PI-IBS was 36 years.The median time to diagnosis in PI-IBS group was significantly longer than that in NPI-IBS group [(19.7 ± 10.3) months vs (11.4 ± 5.3) months,P ＜ 0.05].Similarly,the proportion of anxiety [58.1％ (68/117) vs 28.9％ (58/201),P ＜ 0.05] and the value of I-FABP[(42.6 ± 14.8) μg/L vs (17.3 ± 11.5) μg/L,P ＜ 0.05] in PI-IBS group were significant higher than NPI-IBS patients.The level of I-FABP of healthy controls [(10.6 ± 8.2) μg/L] was also significantly lower than that of PI-IBS patients (P ＜ 0.05),yet no difference from that of NPI-IBS group.The I-FABP value of subgroup PI-IBS patients with diarrhoea (IBS-D) was significant higher than that of NPI-IBS group [(54.8 ± 9.3) μg/L vs (12.3 ± 6.2) μg/L,P ＜ 0.05].However,other parameters including gender,age,GSRS score,and I-FABP value of subgroup constipation (IBS-C) and mix (IBS-M),were not different between PI-IBS group and NPI-IBS group (all P ＞ 0.05).Conclusion PI-IBS is an occult intestinal inflammation disease with mucosa injury.I-FABP might be a potential testing marker for the diagnosis of PI-IBS.

We analyzed 27 cases of Legg-Calve-Perthes disease that were treated by operative methods at the Department of Orthopedic Surgery, Yonsei University College of Medicine from 1975 to 1981. The modalities of treatment were innominate osteotomy in 17 patients; subtrochanteric osteotomy of femur in 4 patients; and adductor-iliopsoas tenotomies in 6 patients. Most of the cases were in Catterall group III or IV diseases with two or more of “head at risk”signs in the preoperative roentgenogram. All but one case were aged more than 7 years at the time of surgery. In all cases clinical and radiological evaluations were performed until the affected femoral head had been fully regenerated. The average period of follow-up was 2 years and 11 months. Final result by Catterall's criteria was good in 15 cases (56%), fair in 7 cases (26%) and poor in only 5 cases (18%). Among 17 cases treated by innominate osteotomy, 13 cases (76%) were in good result and there was no poor result; 15 cases (86%) showed normal containment at the last follow-up x-ray. To compare these end results with those of noncontainment treatment reported by many authors, we were encouraged to proceed our current policy of early definitive containment surgery especially in patients with poor prognostic factors. In cases of estabilshed femoral head deformities that can be confirmed by preoperative arthrography, adductor-iliopsoas tenotomies were useful to restore normal range of motion of hip joint and to prevent further subluxation of the femoral head. The significant prognostic factors at the time of surgery were the patients age; stage of disease; involvement of femoral head; and finally early established irregularities of the femoral head. In every cases of Legg-Calve-Perthes disease these factors should be carefully assessed to make proper decision for the choice of the most effective modality of treatment.

Calcaneal fractures involving subtalar joint can be associated with prolonged and severe disability. Many different methods have been tried for the treatment in order to search for better results. From March 1983 to December 1985, 8 cases of calcaneal fractures involving subtalar joint were treated by open rcduction and internal fixation. and the results were as follows: 1. Satisfactory results were obtained from 7 cases out of 8. 2. Anatomic reduction was obtained by open reduction and internal fixation. 3. When medial approach failed, combined lateral and medial approaches gave better visualization of articular fecets and ensured anatomic reduction.

Soft tissues, which are widespread in body, are derived from a common primitive mesenchyme and the tumors arising from them tend to closely resemble the prototype tissue in varying degree. Some soft tissue tumors have benign course, which can be cured by local excision and the other have malignant course being resistant to therapy and resulting in recurrence to other organ of tissues. The authors reviewed 279cases of soft tissue tumors which had been treated at Department of Orthopedic Surgery in Severance Hospital, Yonsei University College of Medicine from January 1983 to December 1987. 1. Among 279cases of soft tissue tumors, 257(92.1%) were benign and 22(7.9%) were malignant. 2. Benign soft tissue tumors were common two times in female, and malignant tumors were relatively common in male. 3. Common sites of soft tissue tumors were 92 csses about the knee, 69 csses in the hand and wrist, 44 cases in the foot, 26 cases in the leg, 15 cases in the thigh, 14 cases about the elbow, 10 cases in the arm and foresrm. 4. The most common benign tumors was ganglion which was followed by Baker's cyst, hemangioma, fibromatosis, lipoma, epidermal cyst in decreasing order of incidence. Among malignant tumors, fibrosarcoma, malignant fibrous histiocytoma, malignant schwannoma, synovial sarcoma, leiomyosarcoma were common. 5. Most of the benign tumors was taken by locsl excision, and malignant tumors were were trested by wide resection with combination of chemotherapy. 6. Local recurrences of benign tumors were developed in 26(10.1%) out of 257cases, especially in fibromatosis and hemangioma.

The back pain is increasingly becoming a major problem in the elderly people. The cause of back pain in the elderly patient is quite different from in the young subject. And relationship of the occurrence of osteoporosis with the incidence of fractures in general is currently regarded as a major factor. The authors performed clinical observation on 194 elderly patients who were treated for back pain during 5 years period from April, 1983 to April, 1988 at the Department of Orthopaedic Surgery, Severance Hospital and relationship between osteoporosis and compression fracture of spine was reviewed. The results were as follows : l. Among the 194 cases of back pain(28.3% of total admission cases), whose age were over 50: 142 cases were female and 52 cases were male, being more common in female. 2. Most common cause of back pain was the compression fracture of spine : 86 cases(44.3 %). Osteoporosis was associated with 66 cases(76.7%) out of 86 cases. 3. The number of compression fracture in same patient was more frequent in osteoporotic patient and thoracolumber junction (T12, Ll) was the major site of fracture (45.6%). Compression fracture of spine caused by osteoporosis occured at multiple level in 60.6%. 4. Twenty three cases(34.8%) of compression fracture of spine with osteoporosis were found to have previous history of fractures of spine and/or extremities by radiological examination. Regarding this results, compression fractures of spine was not infrequent cause of back pain in the elderly. It was thought that re-fracture of spine should be prevented by vigorous approach against osteoporosis along with the treatment of presenting fracture in these patients.

Since 1952, Ilizarov external fixator has been developed and used for more than 30 years in Russia and world-wide interest on it has been prevalent during last 2-3 years. The fixation of the tension applied thin wires to the metal frame resist flexional and translational deformity just like other extenal fixators. But, it allows cyclic axial micro-motion at the fracture site without loss of reduction so that it can provide good environment for the fracture healing biologically and biomechanically. Another advantage of Ilizarov external fixator is that it permits mobilization of the adjacent joints and weight bearing of the fractured limb during the application of it and shortens the duration of administration. Since 1988, We applied the Ilizarov external fixator for the treatment of diffcult tibial fractures (open comminuted, segmented and comminuted fractures, nonunion, maunion) and obtained good results in 7 cases. So we report our results even if we had limited cases and experiences.

Osteoporosis is a skeletal condition that is characterized by reduction in bone volume and an increased vulnerability to fracture, practically of the proximal femur and vertebrae. Unfortunately, osteoporosis does not usually become obvious until a patient presents with a fracture. For this reason, it has been referred to as the silent epidemic. While radiological examination remains the mainstay of diagnosis, there are certain disadvantages associated with this technique. Almost one third of the skeletal mass must be lost before osteoporosis becomes apparent on a plain radiograph and radiological artifacts are not uncommon. Many methods have been developed for quantitative assessment. of the skeleton. So osteoporosis can be detected early and its progression and response to therapy can be carefully monitored. Recently, quantitative computed tomography(QCT) has been investigated as a means for non-invasive quantitative determination of bone mineral density of the spine. Highly signifcant correlation have been found between vertebral trabecular mineral amount and quantity determined by QCT. Furthermore vertebral strength and failure load have been found to correlate well with trabecular density determined by QCT. Authors has analysed bone mineral density(BMD) of 213 patients who visited Severance Hospital, Yonsei University College of Medicine from Jan. 1988 to Sept. 1989. The aims of this study is to compare BMD of osteoporosis group with that of mormal group, to investigate correlation between BMD and age distribution, and to estimate fracture threshold in osteoporosis group. Following results were obtained:l. After 20 years of age, men lose an average of 0.83 per cent of bone per year, and women lose an average of 0.96 per cent per year. Such lost in women seems to be accelerated during and after menopause. 2. The bone mineral densities for the osteoporosis group are lower than those for the normal group by 28.4% for male and 29.7% for female. There was little difference between sex. 3. It is suggested that 90mg/cm3 of BMD is the fracture threshold for the osteoporosis group. 4. The compression fracture rate among post-menopausal women is 38.8%.
