Objective To compare the clinical therapeutic effects of combination therapy of Sanqitongshu capsule and prednisolone with prednisolone alone in the treatment of acute peripheral facial neuritis. Methods A total of 61 patients with facial paralysis were divided into the treatment group and the control group in the outpatient order. The control group used 20 mg oral prednisolone and accepted the non-specific anti-inflammatory treatment every other day. Medication would stop in a week. Oral administration of vitamin B1 and vitamin B12 was also performed for nerve metabolism improvement for 30 days. The therapy of the treatment group was based on the same treatment of the control group with Sanqitongshu capsule for 30 days. Results After 4 weeks, in the treatment group, 20 patients recovered, 5 markedly effective, and 2 effective, and the total effective rate was 90%. In the Control group, 10 patients recovered, 3 markedly effective, and 2 effective, and the total effective rate was 50.0%. There were significant differences between the two groups (Plt;0.05). Conclusion The clinical effectiveness of Sanqitongshu capsule plus prednisolone is better than that of prednisolone alone in the treatment of acute peripheral facial neuritis.
bjectiveTo observe the effecacy of immunosuppressive agents on modulation of the disorders of inflammatory and antiinflammatory cytokines in acute pancreatitis, and to investigate the mechanism of treatment of acute pancreatitis with immunosuppressive agents. MethodsSD male rats were divided into 6 groups: group 1, the normal control group (n=6); group 2, acute pancreatitis induced by ductual injection of 5%sodium cholate sulfur at the volume of 1.0 ml/kg without treatment (n=8). After the pancreatitis were induced, the rest rats were injected intravenously with 5Fu 40 mg/kg (group 3, n=6); or methylprednisolone 30 mg/kg (group 4, n=6); or cyclophosphamide 20 mg/kg (group 5, n=6); or methotrexate 1.2 mg/kg (group 6, n=6). Twentyfour hours afteroperation, the animals were killed, the blood samples were taken for measurement of TNFα, IL1, IL6 (by bioassay), and IL10, TGFβ (by ELISA) as well as amylase. ResultsThe inflammatory cytokines (TNFα,IL1,IL6 ) and the antiinflammatory cytokines (IL10 and TGFβ), in blood of acute pancreatitis were increased significantly. After treated with immunosuppressive agents, both the inflammatory and antiinflammatory cytokines were decreased in different degrees. Some indexes of the severity of acute pancreatitis, such as amylase and pancreatic weight were improved obviously.ConclusionImmunosuppressive agents can regulate inflammatoryassociated cytokines increased remarkably in the acute pancreatitis. Therefore, improvement of acute pancreatitis can be achieved through rectifying the abnormal immunity and relieving the pathophysiological disorders of the acute pancreatitis by immunosuppressive agents.
【Abstract】 Objective To establ ish a stable animal model for glucocorticoid-induced avascular necrosis of femoral head in rabbits. Methods Thirty-six adult New Zealand rabbits were randomly divided into four groups:ten were injected twice with l i popolysaccharide (group A), ten were treated with a combination of l i popolysaccharideand methylprednisolone (group B), ten were injected three times with methylprednisolone (group C), and six wereinjected normal sal ine as a control (group D). MR imaging was performed in the rabbits before the first injection ofl i popolysaccharide or methylprednisolone, and at 2, 4, and 6 weeks after the last injection of l i popolysaccharide ormethylprednisolone. Histopathological changes in the femoral heads were observed by l ight microscope and transmission electron microscope at the end of six weeks after the injection. Vascular infusion with Chinese ink was made to evaluate the morphological changes of blood vessels in the femoral head. The percentage of trabecular bone area and empty lacunae and microvascular density were measured. According to the histological and MR imaging appearance of the femoral heads in all groups, the incidence of osteonecrosis of every group was calculated. Results Listlessness, blepharal hyperemia,less activity and reduced diet were found in the rabbits of groups A and B after injected with l ipopolysaccharide. At 3 weeks after the final injection, the body weight of groups B and C was decreased. At 4 weeks after the final injection, the body weight of groups A and D was increased. No abnormal signal could be detected on MR images in rabbits of all groupsbefore injection and at 2 weeks after the injection. At 4 weeks and 6 weeks after the last injection, irregular low signal on T1-weighted images and irregular low or high signal on T2-weighted images could be detected on MR images in rabbits of groups B and C, no abnormal signal could be detected on MR images in rabbits of groups A and D. At 6 weeks after the last injection,the trabecular bone of group B became thin and sparse, some were broken. The percentages of empty lacunae were 11.8% ± 4.7%, 34.4% ± 6.2%, 20.0% ± 4.7% and 9.3% ± 4.6%; the percentages of trabecular bone area were 59.2% ± 6.8%, 40.1% ± 6.0%, 51.5% ± 5.6% and 63.2% ± 8.3%; and the microvascular densities were 14.3% ± 2.7%, 4.5% ± 2.1%, 10.2% ± 3.1% and 15.4% ± 4.1% in groups A, B, C and D respectively. There were statistically significant differences between group B and groups A, C, D (P lt;0.01). The fatty tamponade accumulated in the medullary cavity and intramedullary vascular sinusoids were pressed by the l ipocytes and became narrow. Limposomes were found in osteocytes and vascular endothel ia of group B and group C. Osteocytes of group B crimpled and pyknosis or karyolysis of chromatin were observed in these osteocytes, nuclearmembrane of the osteocytes was discontinous. Vascular endothel ia became swollen and the cell junctions widened or were destroyed in groups A and B. The incidence of osteonecrosis in group B (88.9%) was higher than that in group C (22.2%, P lt; 0.05). There was no osteonecrosis occurred in groups A and D . Conclusion Methylprednisolone combined with l ipopolysaccharide can induce typical rabbit model for early avascular necrosis of femoral head.
OBJECTIVE To assess the effect of sodium hyaluronate (HA) for degenerative disorders of the temporomandibular joint (TMJ). METHODS A prospective randomized controlled clinical trial was conducted. The experimental group received injections in the upper compartments of the involved TMJs with 1% HA 6 mg, whereas the control group received prednisolone (PS) 12.5 mg once a week. Three to four injections were as one course. Before and one week after the treatment courses, clinical symptoms, amount of interleukin-6 (IL-6) and total protein of synovial fluid were measured and compared. RESULTS Sixty-seven patients were included and 4 out of them were dropped out. There were 12 males and 51 females, among them, 14 cases with synovitis, 21 with anterior disc displacement without reduction and 28 with osteoarthritis of the TMJ. Thirty-five patients allocated in HA group and 28 in PS group. Both drugs could relieve the clinical symptoms of TMJ degenerative disorders. In HA group, marked improvement rate was 51.43% and failure rate was 2.86%, whereas marked improvement rate 39.29% and failure rate 17.86% in PS group. The declined levels of IL-6 in synovial fluid was notably greater in HA group than those in PS group. CONCLUSIONIntra-articular injection of HA is effective and safe to treat TMJ degenerative disorders with mild adverse reactions, better in terms of effective rate and declined level of IL-6 than PS.
OBJECTIVE To assess the treatment effect of sodium hyaluronate (HA) on experimental temporomandibular joint (TMJ) osteoarthritis of rabbits in comparison with prednisolone (PS). METHODS The upper compartments of both TMJs of 12 Japanese White Ear Rabbits were injected with 0.2 ml of 1.6% papain, 3 days after the right TMJs were injected again with same amount of papain to induce osteoarthritis with different severity levels. Except 1 rabbit was died accidentally. After one week from final injection of papain, the upper compartments of both TMJs of 6 rabbits were injected with HA 1.3 mg, 5 rabbits with PS 1.6 mg weekly for 4 times. At 3, 5 and 7 weeks after the final injection, the rabbits were sacrificed and the TMJs were pathologically examined. RESULTS The TMJs receiving PS showed predominant structural disorganization, and the right TMJs had much severe pathology. The manifestations were fibrillation, thinner or flaking of the articular cartilage of the temporal part of the joint, and the articular surface was covered with fibrous tissue. Whereas the TMJs receiving HA injections demonstrated limited changes of cartilage, less fibrillation, only local loss of cartilage on outside layer of the surface. In vicinity of the defect area, cluster of the chondrocytes appeared. Pathological scores of the TMJs receiving HA were significantly less than those of the TMJs revieving PS. CONCLUSION The results suggest that hyaluronate have effect of cartilaginous reparation and protection for the osteoarthritis of rabbit. While prednisolone has no help or worsened for articular cartilage reparation.
OBJECTIVE To discuss the methods selection on treatment of body surface hemangioma. METHODS From February 1983 to March 2001, 265 patients with different types of body surface hemangioma were treated with prednisone in 94 cases, laser in 102 cases, and plastic surgery operation in 69 cases respectively. RESULTS Followed up 6 months to 15 years, 70 cases with prednisone treatment were cured (74.5%), which meaned the hemangioma was totally removed and no recurrence in 6 months follow-up, 51 cases with laser treatment were cured (50%), while in the plastic surgery operation group, the cure rate was 98.6% (68 cases). CONCLUSION Treatment with prednisone, laser or plastic surgery operation are all effective to body surface hemangioma and proper treatment method should be selected according to different period and different type of hemangioma to improve the therapeutic effectiveness.
In order to study the prophylactic and therapeutic effect of methyl-prednisolone (MP) on traction injury of spinal cord, 48 rabbits were divided into four groups randomly. According to decreasing amount of the amplitude of P1-wave, 50% reduction lasted for 5 min and 10 min with MP as experimental group, and 50% 5 min and 10 min with NS as control, the changes of amplitudes were monitored by, and the function of the spinal cord was assessed. The amounts of MDA and SOD of the spinal cord tissue were determined and the pathomorphological changes of the spinal cord were observed. The results showed that in the experimental groups, the recovery of P1-wave was quicker, the Tarlov and Molt value were decreased, the density of gray matter of the anterior horn and the myelinated nerve fiber of white matter of 100 microns diameter were higher, the SOD and MDA was decreased and the degenerative and necrotic degree of neuron and nerve fiber were milder. Where in the control groups all the above items were just on the opposite. The conclusions list as follows: the application of MP before operation of spinal deformity might prevent traction injury of the spinal cord during operative correction of spinal deformity, and could also minimized the secondary damage to spinal cord from traction injury if MP was used in time. The action to MP were summarized as improving the microcirculation, inhibiting the hyperoxidation of lipid and accelerating the recovery of SCEP.

ObjectiveTo observe the clinical and imaging characteristics of radiation optic neuropathy (RION). MethodsA retrospective clinical study. A total of 43 patients (69 eyes) who were diagnosed with RION at the Chinese PLA General Hospital from 2010 to 2021 were included in this study. There were 23 males (36 eyes) and 20 females (33 eyes). The age of patients at the time of radiation therapy was 49.54±13.14 years. The main dose of radiotherapy for lesions was 59.83±14.12 Gy. Sixteen patients were treated with combined chemotherapeutic agents. The clinical details of best corrected visual acuity (BCVA) and color photography of the fundus were collected. Forty-six eyes underwent optical coherence tomography (OCT), visual field were examined in 30 eyes, magnetic resonance imaging (MRI) were performed in 40 eyes. The BCVA examination was performed using Snellen visual acuity chart, which was converted to minimum resolution angle logarithm (logMAR) visual acuity during recording. Hyperbaric oxygen therapy (HBOT) was performed in 10 patients (13 eyes), 9 patients (12 eyes) were treated with intravenous methylprednisolone (IVMP), 12 patients (23 eyes) were treated with HBOT combined with IVMP and control group of 12 patients (21 eyes) were only treated with basal treatment. And grouped accordingly. To observe the changes in onset, recovery, and final BCVA of the affected eye as well as thickness changes of the retinal nerve fiber layer (RNFL) of the optic disc and inner limiting membrane-retinal pigment epithelium (ILM-RPE) layer of the macular area, and final outcome of BCVA with different treatment modalities in affected eyes. The RNFL and ILM-RPE layer thicknesses were compared between patients with different disease duration as well as between treatment regimens using independent samples t-test. ResultsOf the 43 cases, vision loss was monocular in 17 patients (39.53%, 17/43) and binocular in 26 patients (60.47%, 26/43). The latency from radiotherapy to onset of visual loss was 36.33±30.48 months. The duration of RION ranged from 1 week to 10 years, in which the disease duration of 37 eyes ≤2 months. Subacute visual acuity loss was present in 41 eyes. logMAR BCVA＜1.0, 1.0-0.3, ＞0.3 were 45, 15, and 9 eyes, respectively. Optic disc pallor and optic disc edema were found in 10 (27.03%, 10/37), 3 (8.11%, 3/37) eyes, respectively, within 2 months. The superior RNFL [95% confidence interval (CI) 2.08-66.56, P=0.038] and the outer circle of the inner limiting membrane to retinal pigment epithelium (ILM-RPE) (95%CI 4.37-45.39, P=0.021) layer thinned significantly during the first month. The center of the ILM-RPE layer thickened (95%CI －32.95-－4.20, P=0.015) significantly during the first two months. The inner circle temporal quadrant of the ILM-RPE layer thickened (95%CI －42.22-－3.83, P=0.022) significantly from the third to sixth month, and the RNFL except for the temporal quadrants and the average RNFL, inner circle superior quadrant and outer circle of the ILM-RPE layer thinned significantly after 6 months (P＜0.05). Among the 40 eyes that underwent MRI examination, 33 eyes (82.50%, 33/40) were affected by T1 enhancement of optic nerve, including 23 eyes (69.70%, 23/33) in intracranial segment; 12 eyes with thickening and long T2 signal (36.36%, 12/33). After treatment, BCVA was restored in 17 eyes (24.6%, 17/69) and final BCVA improved in 9 eyes (13.0%, 9/69). There was no significant difference between HBOT, IVMP and HBOT combined with IVMP therapy in improving BCVA recovery or final BCVA compared with the control group, respectively (t=－1.04, 0.61, 1.31, －1.47, －0.42, 0.46; P＞0.05). ConclusionsThe structural damage of the RNFL and ILM-RPE layer occurred during the first month, the RNFL showed progressive thinning during the follow-up period, while the ILM-RPE layer showed thinning-thickening-thinning. MRI shows T1 enhancement of the optic chiasma and segments of the optic nerve, and the enhanced segments are usually accompanied by thickening and long T2. HBOT and IVMP have no obvious effect on RION.
