Objective To investigate the effectiveness of cannulated lag screws combined with lateral supporting plates in the treatment of Hoffa fracture of Letenneur type I and type III. Methods Between May 2004 and April 2011, 11 patients with Hoffa fracture of Letenneur type I and type III were treated, including 6 males and 5 females with an average age of 36 years (range, 25-47 years). Factures were caused by traffic accident in 8 cases, by falling in 2 cases, and by the other in 1 case. Fracture involved the left knee in 7 patients and the right knee in 4 patients. According Letenneur’s classification criteria, there were 7 type I fractures (6 lateral condyle fractures and 1 medial condyle fracture) and 4 type III fractures (3 lateral condyle fractures and 1 medial condyle fracture). Of 11 fractures, 9 were fresh fractures and 2 were old fractures. Two 6.5 mm cannulated lag screws combined with lateral supporting plates were used to fix fractures by anterolateral or anteromedial incision. Results All incisions achieved primary healing with no early complication. All patients were followed up 12-26 months (mean, 15 months). X-ray films showed bone healing with an average healing time of 15 weeks (range, 10-18 weeks). No loosening or breaking of internal fixator was observed; the removal time of internal fixation was 9-15 months (mean, 12 months). Accoding to Letenneur’s functional assessment system, the results were excellent in 7 cases, good in 3 cases, and poor in 1 case at last follow-up. Conclusion Cannulated lag screws combined with lateral supporting plates fixation is effective in treatment of Hoffa fracture of Letenneur type I and type III with a high union rate; anterolateral or anteromedial approach is the first choice for Hoffa fracture of type I and type III, especially for complicating by tibial plateau fracture or patella fracture.

ObjectiveTo compare the outcomes of kidney transplantation (KT) between Tibetan and Han recipients.MethodsPatients greater than 18 years old, who had received the first ABO-compatible KT between April 2006 and March 2017, were retrospectively included. A propensity score matching (PSM) of Tibetans to Hans was performed by 1∶3 ratio. Survival, renal function and adverse events of the two groups were compared.ResultsOf the 1 820 patients who fit the screening criteria, 123 Tibetans and 357 Hans were included after PSM. The median follow-up time was 48 months. There was no statistically significant difference in death-censored grafts survival (P=0.061) or patients survival (P=0.440) between the two groups. The serum creatinine was higher in Tibetans than that in Hans within one year after KT (P<0.05), and the estimated glomerular filtration rate was lower in Tibetans than that in Hans within 5 years after KT (P<0.05), but no difference thereafter (P>0.05). The incidence of delayed graft function in Tibetan patients after operation was higher than that in Han patients (4.9% vs. 1.4%, P=0.037), but there was no significant difference in the incidence of acute rejection, infection, reoperation, or cancer between the two groups (P>0.05).ConclusionTibetans receiving KT achieve excellent and comparable long-term graft and patient survival to Hans, with similar long-term graft function.

【摘要】 目的 探讨肾移植术后药物（环孢素A和钙离子拮抗剂）、口腔卫生与牙龈增生的关系。 方法 随访2003年1月—2010年3月间321例肾移植患者，记录患者术后药物使用和口腔卫生情况，观察牙龈增生程度。结果 〖HTSS〗口腔卫生水平与牙龈增生程度之间存在统计学相关性（rs=0.344，P=0.000），口腔卫生水平越差，牙龈增生越严重。服用环孢素A和钙离子拮抗剂患者（A组）牙龈增生发生率为62.15%，高于单纯服用环孢素A患者（B组）23.40%，二者比较，差异有统计学意义（χ2=39.220，P=0.000）。结论 〖HTSS〗肾移植术后环孢素A和钙离子拮抗剂联合应用明显增加了牙龈增生的发病率。口腔卫生水平与牙龈增生程度之间存在重要关联，口腔卫生差是牙龈增生的危险因素。【Abstract】 Objective To investigate the correlation between drugs (cyclosporine A and calcium channel blocker), oral hygiene and gingival hyperplasia in patients after renal transplantation. Methods We continuously followed up 321 patients undergoing renal transplantation from January 2003 to July 2009 in our hospital. The levels of oral hygiene, medication and gingival hyperplasia were recorded. Results There was a close relationship between the level of oral hygiene and the degree of gingival hyperplasia (rs=0.344, P=0.000). Higher grades of gingival hyperplasia (grades Ⅱ and Ⅲ) were found exclusively in patients who did not have good oral hygiene. There was a higher tendency of developing gingival hyperplasia among patients who received cyclosporine A and calcium channel blocker than those who only received cyclosporine A (62.15% vs. 23.40%; χ2=39.220, P=0.000). Conclusion The prevalence of gingival hyperplasia is higher in renal transplant recipients taking cyclosporine A and calcium channel blockers. There is a significant relationship between the level of oral hygiene and the development of gingival hyperplasia. Poor oral hygiene is a risk factor of gingival hyperplasia.
Objective To explore the clinical value of pleura biopsy and partial pleura cryobiopsy via electronic bronchoscope in diagnosis of unknown exudative pleural effusion. Methods Diagnostic results of 563 patients with unknown exudative pleural effusion were analyzed retrospectively. Bronchoscope and routine pleura biopsy were performed in 187 patients. Bronchoscope and routine pleura biopsy plus partial pleura cryobiopsy were performed in 376 patients. Pathological positive rates of the two groups were compared. Results In the 187 patients examined by bronchoscope and routine pleura biopsy from 2006 to 2008, 161 patients obtained pathological positive results ( 86.1% ) . In the 376 patients examined by bronchoscope and routine pleura biopsy plus partial pleura cryobiopsy from 2009 to 2012, 354 patients acquired pathological diagnosis ( 94.1% ) . There was significant difference between the two groups ( P lt; 0.05) . The main complications were bleeding and local chest pain, and they can be controlled easily. Conclusions Electronic bronchoscope and pleura biopsy can obtain high detection rate of nearly 90% in diagnosis of unknown exudative pleural effusion especially when combined with cryobiopsy of partial pleura. Electronic bronchoscope combined with pleura biopsy or cryobiopsy is an alternative in clinical settings when thoracoscope is unavailable.
This paper proposes a novel metal artifact reduction (MAR) algorithm for dental implants in kilovoltage computed tomography (kVCT) using megavoltage cone-beam computer tomography (MVCBCT). Firstly, two CT images were derived by scanning patient with dental implants using kVCT and MVCBCT. Metal image was derived by thresholding segmentation in kVCT. MVCBCT and kVCT images were fused to generate prior image which was forward projected to get surrogate sinogram of metal trace. The corrected image was generated by filtered backprojection (FBP) reconstruction in corrected sinogram. The results of proposed algorithm were compared with other frequently-used metal artifact reduction algorithm, such as normalized MAR (NMAR), normalized MAR using MVCBCT prior images (NMAR-MV), and linear interpolation MAR (LIMAR). The normalized root mean square deviation (NRMSD) and mean absolute deviation (MAD) were computed. The experiment showed that the proposed method removed serious metal artifacts without introducing new artifacts. The values of NRMSD and MAD for proposed method were the minimum in all methods. The values of NRMSD for NMAR, NMAR-MV, LIMAR and the proposed method were 21.0%, 22.1%, 41.9% and 17.0% respectively. And MAD values of them were 232, 235, 553, 205 HU, respectively. In conclusion, the proposed metal artifact reduction algorithm can successfully suppress metal artifacts for dental implants, and greatly improve the quality of CT image.
ObjectiveTo summarize the perioperative management experience and the treatment strategy of hyperkalemia after simultaneous pancreas and kidney transplantation (SPK).MethodThe clinical data of patients with diabetes combined with end-stage renal disease who accepted SPK in the Organ Transplantation Center of West China Hospital of Sichuan University from November 2017 to November 2019 were retrospectively analyzed.ResultsA total of 6 patients accepted SPK totally. The cold ischemia time of all allografts was less than 8 h. The levels of fasting blood glucose and serum creatinine were normal in the 5 surviving patients, and the diabetic complications were relieved or improved, except for 1 patient who died of cardiac arrest due to acute left heart failure. There were 1 case of delayed primary renal function recovery, 2 cases of bleeding in the surgical area of pancreas transplantation, 1 case of gastrointestinal bleeding, 3 cases of microthrombosis in the blood vessels of pancreas transplantation, 2 cases of perirenal effusion infection, 2 cases of pulmonary infection, and 1 case of ureterobladder anastomotic leakage, all of which were cured after symptomatic treatment. Only 2 patients occurred hyperkalemia after SPK (the highest level was 6.49 mmol/L and 6.67 mmol/L respectively), and transfusion of 10% glucose injection contain insulin, emergency dialysis and oral fludrocortisone were successively performed on them to restore the potassium density in 1 month and 2 months after surgery. There were no complications of perioperative surgical technical hemorrhage, intestinal leakage, large arteriovenous thrombosis, necrotizing pancreatitis, etc.ConclusionsSPK is the most effective treatment for patients with diabetes combined with end-stage renal disease. Transfusion of 10% glucose injection contain insulin, emergency dialysis, and oral fludrocortisone are effective strategies in treating hyperkalemia after SPK.
ObjectiveTo explore the effect of donation after citizen death (DCD) kidney transplantations performed in Sichuan.MethodsThe data of 97 cases of DCD kidney transplantations performed in West China Hospital of Sichuan University between January 2012 and March 2016 was retrospectively reviewed. The 53 donors were aged from 7 months to 54 years (with a median of 28 years, and lower quartile of 15 years and upper quartile of 45 years), including 40 males and 13 females; the causes of death included craniocerebral trauma in 21 cases, craniocerebral tumor in 12 cases, cerebrovascular accident in 15 cases, hypoxic-ischemic encephalopathy in 4 cases, and hydrocephalus in 1 case. The 97 recipients were aged from 18 to 66 years (with a median of 39 years, and lower quartile of 30 years and upper quartile of 44 years), including 71 males and 26 females. The recipients were classified into C-Ⅰ (n=36) and C-Ⅲ (n=61) according to type of donation. The baseline and perioperative situation of the donors and recipients, and the postoperative kidney function, infection, recipient survival and kidney survival of the recipients were analyzed.ResultsAfter transplantation, none of primary graft nonfunction occurred but delayed graft function (DGF) occurred in 26 cases. There were no significant differences in creatinine level between C-Ⅰ and C-Ⅲ recipients at 1 week [(226.71±187.46) vs. (249.94±249.84) μmol/L, P=0.636], 1 month [(136.32±63.34) vs. (157.37±147.83) μmol/L, P=0.428], 3 months [(110.51±25.26) vs. (115.02±36.60) μmol/L, P=0.527] and 12 months [(103.42±21.57) vs. (104.18±39.36) μmol/L, P=0.911] after transplantation, as well as acute rejection [13.9% vs. 19.7%, P=0.469] and complications at early time after transplantation. There were no significant differences in 1-year recipient survival rate (91.7% vs. 93.4%) and 1-year kidney survival rate (100.0% vs. 91.8%) between C-Ⅰ and C-Ⅲ recipients.ConclusionDCD kidney transplantation has excellent short-term outcomes despite a high incidence of early DGF, and may represent another potential method to safely expand the donor pool.
