MethodsThe related literatures in recent years of living donor liver transplantation (LDLT) postoperative complications, quality of life, and liver regeneration were reviewed, and the donors postoperative survival situation were investigated. ResultsLDLT has become an option, It is safe and feasible for healthy adults to donate partial liver for LDLT. ConclusionsDonor postoperative survival situation is very important, and it affect the development of LDLT.To improve donors postoperative survival situation, we still need more efforts.
Objective To systematically review the efficacy and safety of CoenzymeQ10 for Parkinson’s disease. Methods Databases including PubMed, The Cochrane Library (Issue 1, 2015), EMbase, CBM, CNKI, WanFang Data and VIP were searched from inception to August 2015, to collect randomized controlled trials (RCTs) about CoenzymeQ10 for Parkinson’s disease. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed using RevMan 5.3 software. Results A total of 5 RCTs involving 981 patients were included. The results of meta-analysis showed that, a) As for recently effectiveness, CoenzymeQ10 2 400 mg group was superior to the placebo group in total UPDRS score change (MD=1.09, 95%CI 0.94 to 1.24, P < 0.000 01), UPDRS-I score change (MD=0.19, 95%CI 0.17 to 0.21, P < 0.000 01), UPDRS-II score change (MD=0.27, 95%CI 0.21 to 0.32, P < 0.000 01), UPDRS-III score change (MD=0.65, 95%CI 0.54 to 0.76, P < 0.000 01), Hoehn & Yahr score change (MD=0.05, 95%CI 0.04 to 0.06, P < 0.000 01), and Schwab England score change (MD= –0.87, 95%CI –1.02 to –0.72, P < 0.000 01). b) As for long-term effectiveness, there were no differences between two groups, except that the UPDRS-II score change of CoenzymeQ10 1 200 mg group was superior to the placebo group. c) As for adverse reactions, there were no statistical differences between two groups except that the incidence of cholesterol of the CoenzymeQ10 600 mg group and incidence of diarrhea of the CoenzymeQ10 2 400 mg group were lower than that of the placebo group. Conclusion Current evidence shows that, the dosage of 2 400 mg/d CoenzymeQ10 is effective and safe for early Parkinson’s disease. Due to the limited quality and quantity of included studies, more higher quality studies are needed to verify the above conclusion.
ObjectiveTo evaluate the effectiveness of intra-articular radioulnar ligament reconstruction in the treatment of chronic instability of the distal radioulnar joint. MethodsBetween January 2006 and June 2012, the intra-articular radioulnar ligament reconstruction was used to treat chronic instability of the distal radioulnar joint in 12 patients. Of 12 cases, 8 were males and 4 were females with an average age of 37.3 years (range, 22-54 years). The causes of injury were tumble in 9 patients, traffic accident in 2 patients, and sprain in 1 patient. The average time from initial injury to operation was 6.2 months (range, 2-13 months). The pain and function of the wrists were assessed with Patient-Rated Wrist Evaluation (PRWE) (27.5±4.7). Broadening of the distal radioulnar joint space was seen on the anteroposterior radiograph in all the patients. Lateral view showed dorsal instability in 10 patients and palmar instability in 2 patients. There was no radial fracture, ulnar fractures or degeneration of the distal radioulnar joint. ResultsAll patients achieved primary healing of incision. No complication of deep infection or nerve injury occurred. They were followed up from 12 to 30 months (mean, 20.6 months). Pain and the clicking sound of the wrists disappeared; grip strength increased; the range of motion values of the wrist and forearm were restored. PRWE score was 5.8±2.1 at last follow-up, showing significant difference when compared with preoperative score (t=14.215, P=0.000). Imaging examination showed good appositions of the distal radioulnar joint, with no dislocation or subluxation. ConclusionIntra-articular radioulnar ligament reconstruction can rebuild the anatomic stability of the distal radioulnar joint, which does not damage the adjacent structures of the joints and can obtain satisfactory function of the reconstructed joint. It is a good choice for chronic instability of the distal radioulnar joint without articular degeneration.
Objective To investigate the feasibility of bacterial cellulose patch to repair and reconstruct rabbit tracheal defect, so as to lay the foundation for the development of bacterial cellulose artificial trachea. Methods Thirty adult rabbits (weighing, 2.5-3.5 kg) were selected to establish full-thickness defect of the cervical trachea (1.0 cm×0.6 cm in size) which involved the anterior and side walls and 2-3 rings. Defect was repaired with sheet bacterial cellulose (1.2 cm in diameter and 6 layers) in experimental group (n=15), and with autologous cervical fascia in control group (n=15). The general condition of the animals was observed after operation; after 4, 8, and 12 weeks, the samples were obtained for measuring the tracheal stenosis degree, counting new microvessels, and observing lumen reconstruction situation by scanning electron microscope. Results Three rabbits died of infection, tracheal stenosis, or asphyxia caused by airway secretions retention in 2 groups respectively, and the other rabbits survived to the end of experiment. Gross observation showed that reconstruction materials gradually adhered to adjacent tissue and were enwrapped by connective tissue, small blood vessels like nutrient vessel were seen in 2 groups; no significant difference was found in the tracheal lumen stenosis degree between 2 groups (P > 0.05). Histological observation showed that the continuous growth of mucosal epithelial cells was observed near patch and anastomosis site with time, and cell morphology gradually turned mature in experimental group; while mucosal epithelial cells arranged loosely in control group. At each time point, new capillaries of experimental group were significantly more than those of control group (P < 0.05). Scanning electron microscope observation showed the continuous epithelioid cells were observed at anastomosis site with time, and gradually grew into the middle of the patch in experimental group; while less and discontinuous epithelioid cells were observed in control group. Conclusion Bacterial cellulose patch is feasible to reconstruct cervical tracheal defect in rabbits, and the new mucosa is formed early and completely, so it is expected to be used as artificial trachea material.
ObjectiveTo explore the possible association between early injury assessment indexes and the length of stay (LOS) in first-line hospitals, in order to help the hospitals take advantage of resource effectively and transfer victims reasonably during earthquakes. MethodWe retrospectively analyzed the medical information of 3 576 traumatic patients injured in the Wenchuan Earthquake who were transferred to 242 first-line medical institutes between 14:28, May 12th and 14:30, May 19th in 2008. Three kinds of 15 variables were extracted for the analysis, including gender, age, heart or lung disease, pre-hospital time, head injury, trunk injury, open injury, crush injury, asphyxia, body temperature, heart rate, respiration, systolic blood pressure, diastolic blood pressure, and Glasgow coma score. Multiple stepwise linear regression analysis was performed to identify the factors associated with LOS. ResultsThe multiple linear regression analysis showed that age as well as other six factors affected LOS significantly (P<0.05). The partial regression coefficients of age, pre-hospital time, head injury, trunk injury, crush injury, complication of cardiac or pulmonary disease, and Glasgow coma score were -0.062, 0.157, 3.703, 4.111, 12.602, 14.762 and -1.312, respectively. ConclusionsEarthquake trauma patients with older age, long pre-hospital time, head injury, trunk injury, heart or lung disease, crush injury, and lower Glasgow coma score are at increased risk for extended LOS.
ObjectiveTo investigate the effectiveness of pedicle screw internal fixation for the atlantoaxial instability of children. MethodsBetween July 2005 and January 2012, 19 cases of atlantoaxial instability were treated, included 10 boys and 9 girls with an average age of 7.5 years (range, 4-15 years). The X-ray films, CT, and MRI examinations of the cervical spine showed craniocervical malformation in 9 cases, congenital os odontoideum in 3 cases, odontoid fracture (type Ⅱ) in 1 case, disruption of transverse ligament in 2 cases, atlantoaxial fracture and dislocation in 4 cases; and spinal cord injury in 8 cases, according to the American Spinal Cord Injury Association (ASIA) impairment scale, 1 case was rated as grade B, 2 as grade C, and 5 as grade D. Preoperative skull traction was performed routinely on all cases, and complete reduction was achieved in 17 cases, no reduction in 2 cases. In 17 patients who achieved complete reduction, pedicle screw internal fixation was used through posterior approach, including occipitocervical fusion and fixation in 5 cases, and atlantoaxial fusion and fixation in 12 cases; in 2 patients with no reduction, pedicle screw internal fixation was used through posterior approach (atlantoaxial fusion and fixation) after release by transoral approach. ResultsThe operation was successfully performed in all patients. The mean operation time was 89 minutes; the mean intraoperative blood loss was 95 mL; the mean postoperative drainage volume was 73 mL; and the mean hospitalization days were 14 days. The patients were followed up 6-27 months (mean, 18.3 months). Satisfactory atlantoaxial fusion was obtained, and bone fusion was obtained at 3-7 months after operation (mean, 4.5 months). No breakage of screw or rods and re-dislocation occurred during follow-up. At last follow-up, the cervical range of motion (CROM) of the left and right rotation were (62.0±5.9)°and (63.9±3.8)°respectively in 5 patients receiving occipitocervical fusion and fixation, showing significant difference when compared with the values of normal children[(72.3±7.0)°and (74.1±7.6)°, respectively] at the same age (t=-3.915, P=0.018; t=-5.954, P=0.004). The CROM of the left and right rotation were (70.5±5.8)°and (72.7±4.9)°respectively in 14 patients receiving atlantoaxial fusion and fixation, showing no significant difference when compared with normal children at the same age (t=-1.417, P=0.180; t=-1.021, P=0.323). The visual analogue scale (VAS) score was significantly decreased from 7.8±1.1 at pre-operation to 3.5±0.8 at last follow-up (t=17.267, P=0.000). In 8 cases having spinal cord injury, 2 cases were rated as grade C, 1 case as grade D, and 5 cases as grade E according to ASIA impairment scale. ConclusionTechnique of pedicle screw internal fixation has been proven to be an effective treatment for the atlantoaxial instability of children. It plays an important part in relieving pain and limitation of the cervical region.
ObjectiveTo evaluate the short-term effectiveness of unicompartmental knee arthroplasty (UKA) for medial compartmental osteoarthritis of the knee. MethodsBetween January 2008 and October 2013, 18 patients with medial compartmental osteoarthritis of the knee were treated by UKA, including 11 males and 7 females with an average age of 67.2 years (range, 60-72 years). The disease duration ranged from 3 to 5 years (mean, 3.7 years). All patients had loading pain and walk-associated pain of the medial compartmental knee. The preoperative visual analogue scale (VAS) score was 6.8±1.4. The full-length radiograph of lower limb and anteroposterior and lateral radiographs of the knee showed medial compartmental osteoarthritis of the knee. According to Ahlback staging, 8 knees were at stageⅡand 10 knees at stageⅢ. The knee range of motion (ROM) was (112.3±11.3)°, and the angle of genu varus was (13.2±1.3)°. The American Hospital for Special Surgery (HSS) score was 59.0±6.4. ResultsPrimary healing of incision was obtained in all patients, and no infection or lower limb deep venous thrombosis occurred. All of the patients were followed up 6-50 months (mean, 28 months). No prosthetic loosening and dislocation or lesions of contralateral compartment and patellofemoral joint developed. At 6 months after operation, the VAS score was significantly reduced to 2.8±1.2 (t=9.20, P=0.00); most of patients achieved significant relief of pain. The HSS score was significantly increased to 92.0±3.1 (t=19.69, P=0.00); and the results were excellent in 12 cases, good in 5 cases, and poor in 1 case, with an excellent and good rate of 94.4%. The knee ROM was (115.2±10.2)°, showing no significant difference when compared with preoperative one (t=-0.81, P=0.23). The alignment of limbs showed that the angle of genu varus was significantly reduced to (6.8±2.1)° (t=10.99, P=0.00). ConclusionUKA has satisfactory short-term effectiveness in the treatment of medial compartmental knee osteoarthritis, however, long-term effectiveness need further studies.
ObjectiveTo investigate the feasibility, safety and effectiveness of video-assisted thoracic surgery (VATS) sympathectomy under monitored anesthesia care (MAC) and local anesthesia (LA) without endotracheal intubation as a new fast track recovery surgical strategy for the treatment of palmar hyperhidrosis. MethodsA total of 124 patients with intermediate or severe hyperhidrosis who were admitted to Guangdong General Hospital were enrolled in this study. With SPSS18 random number generator, all the patients were divided into MAC+LA group and general anesthesia (GA) group with 62 patients in each group. There were 43 males and 19 females in MAC+LA group with their age of 22.25±6.22 years, and 42 males and 20 females in GA group with their age of 23.98±6.67 years. During the surgery, MAC+LA group patients received MAC and oxygen via nasal tube or face mask instead of endotracheal intubation, and GA group patients received GA, endotracheal intubation and controlled ventilation. Clinical outcomes were compared between the 2 groups. ResultsAll the patients received their operations safely. None of MAC+LA group patients received conversion to GA and controlled ventilation. There was statistical difference in operation time (47.18±12.06 minutes vs. 39.33±13.21 minutes, P=0.002) and length of theatre stay 84.52±22.56 minutes vs. 134.68±26.12 minutes, P=0.000) between MAC+LA and GA group patients. There was no statistical difference in blood loss, incidence of intraoperative SpO2 lower than 95% (2 patients vs. 0 patient), postoperative hospital stay, incidence of postoperative compensatory sweating (86.5% vs. 89.0%) and patient satisfaction rate (94.59% vs.95.12%) between the 2 groups. No intraoperative pain, postoperative complication or symptom recurrence was observed in either group. There was statistical difference in anesthetic preparation time (20.52±10.55 minutes vs. 36.47±12.16 minutes), duration between operation finish and returning to ward (11.26±7.09 minutes vs. 59.39±19.89) minutes and hospitalization cost (RMB 6 376.86±746.00 yuan vs. RMB 8 812.04±867.93 yuan) between the 2 groups. The incidence of postoperative sore throat (0% vs. 100%), monitor time (4 hours vs. 12 hours) and time to resume oral intake (2 hours vs. 6 hours) of MAC+LA group were significantly lower or shorter than those of GA group. ConclusionVATS sympathectomy under MAC and LA can avoid complications of GA and endotracheal intubation, and provide a safe, feasible, effective and more minimally invasive fast track alternative for the treatment of palmar hyperhidrosis.
