Objective To evaluate the results of operative treatment of acetabular fractures and to investigate its influence factors. Methods The cl inical data were analyzed retrospectively from 82 patients with acetabular fractures treated between September 2004 and June 2009. Of 82 patients, 65 were male and 17 were female, aged 26-72 years (mean, 38 years).Fractures were caused by traffic accident in 62 cases, by crush in 13 cases, and by fall ing from height in 7 cases. The time from injury to admission was 30 minutes to 12 days (median, 7.6 hours) in 70 cases, 12 cases were transferred because poor result after 34-67 days of conservative treatment. According to Judet classification, there were 24 cases of posterior wall fracture, 3 cases of posterior column fracture, 1 case of anterior wall fracture, 2 cases of anterior column fracture, 6 cases of transverse fracture, 16 cases of transverse and posterior wall fracture, 4 cases of posterior column and posterior wall fracture, 5 cases of T-type fracture, 3 cases of anterior and posterior hemitransverse fracture, and 18 cases of complete both-column fracture; 24 cases combined with dislocation of the hip. During operation, Kocher-Langenbeck approach was used in 49 cases, anterior il ioinguinal approach in 19 cases, and the combination of anterior and posterior approaches in 14 cases. Reconstructive plate (74 cases) and hollow lag screw (8 cases) internal fixation were used. The function of the hip was evaluated according to the modified Merled’Aubigne- Postel hip score system postoperatively. According to fracture type, age, lower extremity fracture before operation, qual ity of reduction, timing of surgery, hi p dislocation and time of reduction, operative approach, deep vein thrombosis (DVT), and heterotopic ossification (HO), the patients were divided into the groups and the results were compared. Results Accordancewith the Matta X-ray evaluation criteria, anatomic reduction was achieved in 21 cases, good reduction in 37 cases, fair reduction in 16 cases, and poor reduction in 8 cases, and the excellent and good rate was 71%. All the cases were followed up 12-52 months mean, 34 months). Iatrogenic sciatic nerve injury occurred in 8 cases, infection in 3 cases, HO in 16 cases, DVT in 3 cases, hip posttraumatic arthritis in 12 cases, and avascular necrosis of the femoral head in 9 cases. X-ray examination showed that 80 cases achieved fracture union at 10-24 weeks after operation (mean, 14 weeks) and 2 cases had fracture delayed union at 10 months and 12 months after operation. According to the modified Merled’Aubigne-Postel hip score system, the function of the hip was rated as excellent in 26 cases, good in 32, fair in 20, and poor in 4 at 6 months after operation; the excellent and good rate was 71%. The affecting factors of cl inical results of acetabular fractures were fracture type, age, lower extremity fracture before operation, qual ity of reduction, timing of surgery, hip dislocation and time of reduction (P lt; 0.05). However the operative approach, DVT, and HO were not affecting factor of the acetabular fractures (P gt; 0.05). Conclusion Operative treatment of acetabular fractures has a satisfying therapeutic effect. Fracture type, age, lower extremity fracture before operation, qual ity of reduction, timing of surgery, hip dislocation, and time of reduction are risk factors affecting postoperative results.
Objective To investigate the preparing procedures for the larger chemically acellular nerve allografts (CANA) and to establish an evaluation criteria and the preparation method.Methods The sciatic nerves ofthe dogs were exposed by a muscle-splitting incision and were isolated free of the underlying fascia. The 50-mm-long segments of the nerve were made. The proximal and distal ends of the nerve segments were labelled and stabilized by pinning the ends to a thin plastic support, and then they were treated according to the following decellularization processes: The nerve segments were rinsed with the distilled water for 9h, transferred in a 3% Triton-100 solution for 12 h, soaked in 7% sodium deoxycholate for 12 h, and washed in the distilled water for 6 h. All the decellularization steps were performed at room temperature. The nerve segments were divided into 5 subgroups. In Group Ⅰ, Group Ⅱ and Group Ⅲ, the nerve segments were decellularized for 2, 3 and 4 times, respectively. In Group Ⅳ and Group Ⅴ, the two ends of the nerve segments were ligated with a silk line and were decellularized for 2 and 3 times, respectively. Each nerve segment was subdivided into 5 portions from the proximal end to the distal end. The degrees of decellularization, activity of Laminin, degrees of demyelination, and integrity of the nerve fiber tube were observed under microscope and were assessed by a scoring system. Results In all the groups the activity of Laminin was present and the degrees of decellularization were complete. As for the demyelination of the nerve segments, the myelin sheath in Groups Ⅰ, Ⅱ and Ⅲ was partially preserved, but it completely disappeared in Groups Ⅳ and Ⅴ. The structure of the nerve fiber tube in Groups Ⅰ and Ⅳ was almost normal. The total score for the degrees of decellularization, demyelination, and structural integrity was the lowest in Group Ⅳ but the quality was the best. Conclusion The degrees of demyelination are not parallel to the times of decellularization processes. In the quality control of CANA, we should consider the following 4 factors: activity of Laminin, degrees of decellularization, demyelination, and structural integrity. For the larger CANA,ligation of the two ends of the nerve segments during the decellularization procedure may be a better method of ensuring the quality of the decellularization.

Operative procedure (RR=0.165), differentiated degree (RR=2.692), lymph node metastasis (RR=3.014), neural infiltration (RR=2.857), and vascular infiltration (RR=2.365) were found to be the statistically significant factors that influenced survival by multivariate factor analysis through the Cox proportional hazard model.
ConclusionsRadical resection is the best treatment for hilar cholangiocarcinoma. Skeletonized hepatoduodenal ligament, complete excision of infiltrated nerve and blood vessel are important influence factors to improve the prognosis of hilar cholangiocarcinoma.
ObjectiveTo discuss and analyze the sense of dignity and its influencing factors of maintenance hemodialysis (MHD) patients.MethodsPatients with MHD in hemodialysis center of West China Hospital of Sichuan University were selected from November 2019 to January 2020. Patients were selected by convenience sampling. The patients were investigated with Patient Dignity Inventory (PDI), Connor-Davidson Resilience Scale (CD-RISC) and Hospital Anxiety and Depression Scale.ResultsA total of 150 patients were included. The average scores of CD-RISC, anxiety, depression and PDI were 61.20±14.54, 4.97±1.38, 5.90±2.42 and 41.32±16.24, respectively. Among them, 121 cases (80.67%) had mild dignity impairment, 22 cases (14.67%) had moderate dignity impairment, 6 cases (4.00%) had severe dignity impairment, and 1 case (0.67%) had very serious dignity impairment. The results of multiple linear stepwise regression showed that depression, economic burden, social support, and vascular access were all positive predictors of esteem scores (P<0.001).ConclusionsClinical nurses can aim at the main factors affecting the sense of dignity of MHD patients. And individualized nursing plan and intervention measures can be formulated to improve the sense of dignity of patients and improve the quality of life of maintenance hemodialysis patients.
Objective To evaluate the results of operative treatment of complex acetabular fractures and to investigate its influence factors. Methods From June 2000 to August 2006, 54 patients with complex acetabular fractures were treated, including 44 males and 10 females aged 20-75 years old (average 39.1 years old). Fractures were due to traffic accidentin 40 cases, fall ing from high places in 8 cases and crush by heavy objects in 6 cases. All cases were fresh and close fractures and the time from injury to operation was 5-72 days. There were 5 cases of posterior column and posterior wall fracture, 25 of transverse and posterior wall fracture, 2 of T-type fracture, and 22 of double column fracture. During operation, Kocker- Lagenbach approach was used in 23 cases, anterior il ioinguinal approach was appl ied for 3 cases and the combination of anterior and posterior approaches was performed on 28 cases. AO reconstructive plate and screw internal fixation were used in all the cases. Results Fifty-two cases were followed up for 12-74 months (average 31.3 months). Anatomical reduction was achieved in 23 cases, satisfactory reduction in 19 cases, poor reduction in 10 cases, and the excellent and good rate reached 80.77%. During operation, 1 case suffered from a tear in the external il iac vein and healed after vein repair; 2 cases had sciatic nerve injury and took mecobalamin as oral administration, one of them fully recovered, and the other had incomplete recovery at 18-month follow-up. At the final follow-up, there were 6 cases of severe heterotopic ossification, one of them received heterotopic bone resection and the rest 5 patients received conservative treatment; there were 9 cases of traumatic osteoarthritis, one of them received total hip replacement and the rest 8 patients received conservative treatment; there were 5 cases of avascular necrosis of the femoral head, two of them received total hip replacement, 1 received no further treatment because the femoral head didn’ t collapse, and the rest 2 patients gave up total hip replacement; 75.00% patients were graded as excellent and good according to the modified Merled’Aubigné-Postel hip score system. Patients’ qual ity of l ife was compared with local population normsmatched for age and sex by using SF-36 scales, their overall score were below the local population norms, and their general health, vital ity, role l imitation due to emotional problems and mental health were comparable to the local population norms. Logistic regression analysis revealed the time to reduce hip dislocation, qual ity of fracture reduction nd traumatic arthritis were independent risk factors affecting postoperative functional outcomes. Conclusion Applying open reduction and internal fixation in the treatment of displaced complex acetabular fractures has a satisfying therapeutic effect. Time to reduce hip dislocation, qual ity of fracture reduction as well as traumatic arthritis are independent risk factors affecting postoperative functional outcomes.
ObjectiveTo observe the clinical effect of vitrectomy with internal limiting membrane peeling and air tamponade in the treatment of idiopathic macular hole (IMH).MethodsA prospective, non-randomized controlled case cohort study. Twenty eyes of 20 patients with IMH in Ophthamology Department of The Second Hospital of Jilin University from September 2016 to January 2017 were included in this study. There were 4 males (4 eyes) and 16 females (16 eyes), with the mean age of 60.60±9.50 years and the mean disease course of 9.55±15.5 months. The stage of macular hole ranged from Ⅱ to Ⅳ. All patients underwent BCVA, intraocular pressure, spectral-domain OCT (SD-OCT) and multifocal ERG examinations. The BCVA examination was performed using the international standard visual acuity chart, which was converted into logMAR visual acuity. The minimum diameter (MIN), bottom diameter (BD), height (H), the defective diameter of ellipsoid zone, the defective diameter of external limiting membrane (ELM) of the macular hole were measured by SD-OCT (German Heidelberg). Then the macular hole index (MHI=H/BD), hole traction index (THI=MD/BD) and hole diameter index (DHI=H/MD) were calculated. The response density in P1 wave was detected by mf-ERG. The logMAR BCVA was 1.18±0.54. There were 5 eyes with less than 400 μm MIN, 13 eyes with 400-700 μm MIN and 2 eyes with over than 700 μm MIN. All the patients were underwent vitrectomy with internal limiting membrane peeling and air tamponade. According to the SD-OCT image features after surgery, IMH closure was divided into type Ⅰ closed, type Ⅱ closed and unclosed. The follow-up was equal or greater than 3 months. The closure rate of IMH, BCVA and the changes of microstructure parameters of macular area were observed. Spearman correlation analysis was used to analyze the correlation between BCVA and the wave response density in P1 before surgery and the efficacy after IMH surgery.ResultsClosure rate of IMH: 18 eyes (90.0%) were completely closed (all type Ⅰ closed). The closure rate of macular hole with the MIN less than 400 μm was 100.0% (5/5), 400-700 μm was 92.3% (12/13), and over than 700 μm was 50% (1/2). BCVA: the mean logMAR BCVA at 1 week, 1 month, 3 months after surgery were 0.83±0.54, 0.65±0.41, 0.48±0.34, and there was statistically significant difference between preoperative and postoperative BCVA (t=3.382, 4.459, 5.250; P=0.003, 0.007, 0.004). The outcomes of SD-OCT at 3 months after surgery: 18 eyes (90.0%) with intact ELM. The defective diameter of ellipsoid zone was 260.34±272.08 μm, there was statistically significant difference between before and after surgery (t=13.545, P=0.002). The outcomes of mf-ERG: the P1 wave response density of the ring 1 and ring 2 after surgery were increased compared with before surgery (t=-16.748, -6.151; P＜0.01,＜0.01). The results of Spearman correlation analysis: there was a positive correlation between postoperative BCVA and preoperative MIN, the defective diameter of ellipsoid zone and ELM, and postoperative the defective diameter of ellipsoid zone (r=0.56, 0.59, 0.68, 0.52; P=0.010, 0.006, 0.001, 0.019). The postoperative BCVA was negatively correlated with the P1 wave response density of ring 1 and ring 2 of mf-ERG (r=－0.34, －0.16; P=0.006, 0.020). The IMH closure had a significant negative correlation with MIN and the defective diameter of ELM (r=－0.449, －0.449; P=0.047, 0.047). MHI and THI were positively correlated with the closure of the hole (r=0.474, 0.546; P=0.035, 0.013). Intraocular pressure increased in 2 eyes during the follow-up period, and returned to normal within 1 week after the administration of antihypertensive drugs. There were no complications during or after the operation.ConclusionsVitrectomy with internal limiting membrane peeling and air tamponade in the treatment of IMH is safe and effective. The MIN, MHI THI are significantly correlated with the curative effect after IMH surgery, which could be used as the index to predict and evaluate the curative effect. The response density of ring 1 and ring 2 in P1 wave of mf-ERG is signifi-cantly improved compared with before surgery, and which is negatively correlated with BCVA.
ObjectiveTo investigate the risk factors of postoperative portal vein thrombosis (PVT) after devascu-larization in patients with cirrhotic portal hypertension.
MethodsThe clinical data of 40 patients with cirrhotic portal hypertension treated with splenectomy and gastric pericardial devascularization were retrospectively analyzed to investigate the related risk factors.
ResultsA total of 12 of the 40 patients suffered from PVT (30.00%). The results of multivariate analysis showed that portal vein diameter, postoperative portal vein velocity, platelet count at 2 weeks postoperatively, and postoperative portal vein pressure were the factors influencing the incidence of PVT after devascularization. Patients with the greater portal vein diameter and platelet count at 2 weeks postoperatively, the lower postoperative portal vein velocity and postoperative portal vein pressure, had higher ratio of PVT (P < 0.05).
ConclusionPortal vein diameter, portal vein blood flow velocity, platelet count, and postoperative portal vein pressure were the main risk factors for PVT after surgery in patients with cirrhotic portal hypertension.
Objective
To investigate the medical charge of in-patients with diabetes and its influencing factors for effective hospital costs controlling.
Methods
The inpatients with diabetes (the first diagnosis was diabetes; the first three ICD-10 codes of which were between E10 to E14) in Fifth Peoples' Hospital of Chengdu during January to September of 2014 were analyzed for their hospital costs with descriptive statistical method, ANOVA and multiple linear regression method. Statistical analysis was conducted by using SPSS 18.0 software.
Results
A total of 1 389 cases of diabetes were included. The median of total medical costs and daily costs were 4 554.45 yuan and 446.46 yuan, respectively. The differences of total medical costs and daily costs between diabetes patients with different amount of complications were statistically significant (P<0.001). The factors including age, the way of the medical expense, the number of complications, with acute complications, CCI score and the hospital-stay length were proved to be significantly correlated to total medical costs of diabetes inpatients (P<0.05).
Conclusion
Age, the way of the medical expense, the number of complications, with acute complications, CCI score and the hospital-stay length are influence factors of medical costs of diabetes inpatients.
ObjectivesBased on the historical data of inpatients, a logistic regression model was established. It aimed to identify the influencing factors of patient's admission scheduling decisions and compare them with the actual scheduling rules, so as to discover the differences and deficiencies.MethodsWe extracted data of outpatients and inpatients in Department of Respiration in West China Hospital of Sichuan University from January 1st, 2016 to December 31st, 2016, and standardized the original dataset. We established the binary multivariate logistic regression model through R software and ‘glm’ package.ResultsThe analysis of multi-factor logistic regression showed that the effect of the five variables (type of medical insurance, time of registration, waiting time, type of disease and admission priority) on patient schedule was statistically significant.ConclusionsThe logistic regression model constructed in this study has a good effect on patient planning, which is helpful to provide decision support for admission schedule through identification factors.
