RESUMO
Objective:To treat the mixed and deeper infantile hemangioma with ladder dosage propranolol, and to explore its efficacy and safety.Methods:A total of 98 infants with hemangioma were treated by ladder treatment of propranolol.Before treatment,comprehensive assessments of electrocardiogram(ECG),heart color ultrasound, blood glucose,liver function,kidney function,myocardial enzymes and blood routine were conducted.After excluding contraindications,the dose of propranolol incrementally doubled from 0.5 mg·kg-1·d-1 to 4.0 mg·kg-1·d-1.Propranolol was taken 3 times a day.Before and after medication for 1 and 2 h,ECG was monitored.The changes of tumor size,texture,color and other changes or an onset of adverse reactions were dynamicly observed.The infants were visited every month.The efficacy was evaluated using Achauer system.Results: After medication,98 cases had different degrees of color changes or tumor consistency softening.After the dosage of propranolol was increased to 4.0 mg·kg-1·d-1,the change of tumor was the fastest.According to the 4-grade method, there were 84 cases(85.71%) as gradeⅣ (excellent),2 cases (2.04%) as grade Ⅲ (good),4 cases (4.08%) as gradeⅡ (medium)and 8 cases (8.16%) as gradeⅠ (poor).The curative effect of mixed hemangioma was better than that of deeper hemangioma(P<0.05).The recovery time of 74 cases of hemangiomas was 6 months.The major adverse reactions were heart rate decline(5/98,5.10%),drowsiness(3/98,3.06%),diarrhea(7/98,7.14%),loss of appetite (1/98,1.02%), and convulsions (2/98,2.04%).After treatment,all adverse reactions disappeared.Two months after drug withdrawal there were 4 cases of recurrence,and they were continously treated with propranolol.Conclusion: The efficacy of oral ladder dosage propranolol in treatment of mixed and deeper infantile hemangioma is increased significantly and there are no significant adverse reactions.
RESUMO
BACKGROUND:At present, it remains unclear whether delayed functional exercises after arthroscopic rotator cuff repairs could elevate the healing rate of tendon. The opportunity of functional exercises after rotator cuff repairs is stil controversial, and there is no relevant system evaluation. OBJECTIVE:To systematical y evaluate the differences in curative effects of early and delayed functional exercises after arthroscopic rotator cuff repairs. METHODS:We searched the Pubmed, EMBASE, Cochrane Central Register of Control ed Clinical Trials, Chinese Biomedical Literature Database, Wanfang Data, China National Knowledge Infrastructure, and Chongqing VIP Database. The key words were“arthroscopy, rotator cuff, rehabilitation”. The references of the included literatures were re-retrieved. The deadline of retrieval was August 15, 2012. The included literatures were randomized control ed trials on early and delayed functional exercises after arthroscopic rotator cuff repairs. Methodological quality evaluation, screening and heterogeneous test were conducted. REVMAN5.1 software was utilized to analyze the extracted data. RESULTS AND CONCLUSION:We included three randomized control ed trials, including 237 patients:119 in the early movement group and 118 in the delayed movement group. During fol ow-up at 1 year after operation, no significant differences in range of motion, pain degree, American Shoulder and Elbow Surgeons Scale, Simple Should Test scores and re-tear rate of rotator cuff were detected between the two groups. Results confirmed that compared with delayed functional exercises, early functional exercises after arthroscopic rotator cuff repair did not have advantages on the improvement of joint function and range of motion, but also did not negatively affect cuff healing. Postoperative rehabilitation can be modified to ensure patient’s compliance.
RESUMO
BACKGROUND:Most of lumbar degenerative diseases, such as lumbar instability, lumbar disc herniation and discogenic lumbago, need lumbar spinal fusion for the spine stability, but the choice of internal fixation approaches is controversial. OBJECTIVE:To compare the effectiveness between lateral lumbar interbody fusion with single cage and single cage combined with unilateral pedicle screw fixation for the 4th and 5th single-level lumbar degenerative disease. METHODS:The clinical data of patients with single-level lumbar degenerative diseases (L4 and L5) undergoing lateral lumbar interbody fusion with single cage in 30 cases (experimental group) and single cage combined with unilateral pedicle screw fixation in 45 cases (control group) were analyzed retrospectively, and the curative effects were compared between the two groups. RESULTS AND CONCLUSION:Al patients in the two groups were fol owed up for 13 months on average (ranged from 10 to 37 months). The incisions in the two groups were stage I healing. One case in the experimental group occurred cage displacement, but no obvious syndromes were detected. No significant difference in the effective rate after operation, hospital stay, and volume of drainage was detected (P>0.05). The operative time and bleeding volume in experimental group were better than those in the control group (P0.05). The effectiveness of lateral lumbar interbody fusion with single cage and single cage combined with unilateral pedicle screw fixation for single-level degenerative lumbar diseases was similar. However, the former has the advantages of less invasion and quick recovery.
RESUMO
Objective To investigate the effect of ellagic acid extracted from gallnut on multiple myeloma SP2 / 0 cell line and related mechanisms. Methods Multiple myeloma SP2 / 0 cell line was treated for 48 h with different concentrations of ellagic acid in vitro. Cell morphology,proliferation,apoptosis and cell cycle were analyzed with microscope,MTT experiment and flow cytometry,respectively. Tumor cell proliferation and apoptosis-related gene expression of COX-2 were detected by Western blotting. Results Cell cycle was arrested at the G1 phase 48 h after treatment with ellagic acid, the cell in G1 were (55. 21±3. 01)% , (64. 48 ± 0. 43)% , (75. 10 ± 2. 46)% , respectively, with significant difference as compared with control group [(34. 04±1. 74)% ,P<0. 01]. Cell suppression rate (21. 18±5. 92)% ,(44. 58±3. 43)% and (70. 15±2. 90)% ,respectively, in 20,40 and 60 μg·mL-1 ellagic acid treatment groups. Compared with the control group,the differences were significant (P<0. 01). Cell apoptosis rate was (9. 60 ± 0. 56)% , (19. 30 ± 1. 51)% and (35. 10 ± 5. 26)% , respectively, in 20,40 and 60 μg·mL-1 ellagic acid treatment groups,with significant differences as compared with the control group[(3. 23±0. 85)% ,P<0. 01]. With the increase of drug concentration,COX-2 expression was decreased. Conclusion Ellagic acid can inhibit myeloma SP2 / 0 cell proliferation and promote apoptosis.
RESUMO
Objective Inflammatory response is an important part in pathological change of traumatic arthritis(TA).Studies show that hydrogen has antioxidate and anti-inflammatory properties, however, there are few reports on treating TA with it.So this research aimed to investigate curative effects of curing traumatic arthritis in rabbits with intraperitoneal injection of saturated hydrogen saline solution . Methods A total of 26 New Zealand white rabbits were divided into three groups:normal control group (n=6), model experimental group (n=10), and model control group (n=10).Rabbits in model experimental group were intraperitoneally injected with 8 ml /kg saturated hy-drogen saline, once every three day;equivalent saline was injected in rabbits of model control group;while no treatment was done on normal control group.The treatment lasted for 6 weeks.Before and after the treatment, the serum and joint fluid of the rabbits in the three groups were respectively taken to determine the content of nitric oxide (NO) and hyaluronic acid (HA), which was used to evaluate therapeutic effect in combination with the behavioral performance of the rabbits . Results Significant improvement in behavior was found in model ex-perimental group after the treatment (P0.05), but model experimental group was superior to model control group in knee swelling scores after the treatment (P0.05).The content of serum HA in model experimental group declined dramatically (P<0.05) and the joint fluid increased after the treatment ([1.72 ±0.37] vs [2.47 ±0.62],P<0.05), while no significant changes were found in model control group before and after the treatment. Conclusion The intraperitoneal injec-tion of saturated hydrogen saline may be effective in the treatment of trau-matic arthritis.
RESUMO
In this paper,we study on turbidity-toxin from the connotation,the pathological characteristics and process of diabetes,and explored the relationship of type 2diabetes with abnormal lipid metabolism and lipid toxicity.We found that insulin resistance,apoptosis of Islet,cell and various complications caused by abnormal lipid metabolism and lipid toxicity had signifi cant correlation with the process of the generation and variation of turbidity-toxin:it was argued that blood turbidity and its subsequent toxin accumulation were the pathogenic basis of the formation,combing with the turbidity-toxin,phlegm and blood stasis,then various complications occurred.So it provided a good theoretical and practical foundation for further treatment of type 2 diabetes associated with abnormal lipid metabolism by removing turbidity and detoxication.
