Objective To study the influence factors of surgical site infection (SSI) after hepatobiliary and pancreatic surgery. Methods Fifty patients suffered from SSI after hepatobiliary and pancreatic surgery who treated in Feng,nan District Hospital of Tangshan City from April 2010 and April 2015 were retrospectively collected as observation group, and 102 patients who didn’t suffered from SSI after hepatobiliary and pancreatic surgery at the same time period were retrospectively collected as control group. Then logistic regression was performed to explore the influence factors of SSI. Results Results of univariate analysis showed that, the ratios of patients older than 60 years, combined with cardiovascular and cerebrovascular diseases, had abdominal surgery history, had smoking history, suffered from the increased level of preoperative blood glucose , suffered from preoperative infection, operative time was longer than 180 minutes, American Societyof Anesthesiologists (ASA) score were 3-5, indwelled drainage tube, without dressing changes within 48 hours after surgery, and new injury severity score (NISS) were 2-3 were higher in observation group (P＜0.05). Results of logistic regression analysis showed that, patients had history of abdominal surgery (OR=1.92), without dressing changes within 48 hours after surgery (OR=2.07), and NISS were 2-3 (OR=2.27) had higher incidence of SSI (P＜0.05). Conclusion We should pay more attention on the patient with abdominal surgery history and with NISS of 2-3, and give dressing changes within 48 hours after surgery, to reduce the incidence of SSI.
ObjectiveTo evaluate the pattern and predictive factors of regional lymph node metastasis in papillay thyroid carcinoma (PTC). MethodsThe clinical data of 223 patients with PTC whom suffered operation from Dec.2008 to Dec.2011 in our hospital were retrospective analyzed.The relationship among the lymph node metastasis of different area of the neck and patient's sex, age, preoperative TSH level, tumor size, multifocality, extracapsular spread, Hashimoto thyroiditis, nodular goiter, and the T classification of the tumors were analyzed. ResultsThe univariate analysis results showed that patient's age≥45 years old and associated with nodular goiter were statistically significantly related to central lymph node metastasis (P < 0.05), for lateral lymph node metastases, the multifocality were statistically significant (P < 0.05).The multivariate analysis results showed that patient's age≥45 years old and associated with nodular goiter were protective factors for central lymph node metastasis (P < 0.05), for lateral lymph node metastasis, the multifocality was risk factor (P < 0.05).Most of the lateral lymph node metastases were confined to levels Ⅱ-Ⅳ, and the incidence of level Ⅲ was as highest as 100%.When the skip metastasis, the levels Ⅱ-Ⅳ were the transfer of high incidence areas. ConclusionsWhen age < 45 years old of patients with PTC, the central neck dissection should be routine performed.The incidence of central lymph node metastasis will decrease if associated with nodular goiter.Because multifocality is a risk factor for lateral lymph node metastasis, careful inspection levels Ⅱ-Ⅳ should be performed during operation, espe-cially level Ⅲ lymph nodes.If skip metastasis is present, levels Ⅱ-Ⅳ dissection would be a proper treatment option.
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.
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 clinical and pathological factors associated with simultaneity peritoneal metastasis of colorectal cancer. Methods Clinical data of 1 593 patients with simultaneity peritoneal metastasis of colorectal cancer who treated in Suqian People’s Hospital and Nanjing Drum Tower Hospital from 2010-2014 were collected to analyze the risk factors of simultaneity peritoneal metastasis of colorectal cancer. Results There were 40 patients (2.5%) suffered form simultaneity peritoneal metastasis of the 1 593 patients with colorectal cancer. The result of univariate analysis showed that, age, diameter of tumor, level of carcino-embryonic antigen (CEA), level of CA19-9, level of CA-125, T staging, differentiation, pathological type, and combining with diabetes were risk factors of simultaneity peritoneal metastasis of colorectal cancer, that incidence rates of simultaneity peritoneal metastasis in patients with ≥ 65 years old, diameter ≥ 5 cm, increase of CEA, CA19-9, and CA-125, later staging of T staging, poorly differentiated, signet ring cell carcinoma/mucinous adenocarcinoma, and combining with diabetes were higher (P<0.05). The result of logistic regression showed that, level of CA19-9, level of CA-125, T staging, combining with diabetes, differentiation, and pathological type were the risk factors of simultaneity peritoneal metastasis of colorectal cancer, that incidence rates of simultaneity peritoneal metastasis in patients with increase of CEA and CA-125, later staging of T staging, poorly differentiated (compared with well differentiated), mucinous adenocarcinoma (compared with adenocarcinoma), and combining with diabetes were higher (P<0.05). Conclusion Increase of CEA and CA-125, T staging, poorly differentiated, mucinous adenocarcinoma, and combining with diabetes are independent risk factors for simultaneity peritoneal metastasis of colorectal cancer.
ObjectiveTo analyze the influence factors of the stable angina pectoris patients' medication compliance based on health belief model. MethodsFrom January to December, 2013, 107 patients with stable angina pectoris were interviewed using the self-design questionnaires, and multiple stepwise linear regression statistical was used to analyze. ResultsThe influence factors of increasing medication compliance were as follows:"myocardial infarction can lead to death", "patients with stable angina pectoris may suffer a sudden myocardial infarction", "over the past year the number of the angina pectoris", "standard treatment is good for prevention of myocardial infarction", "suffering myocardial infarction, even if not dying, there is no more chance to live", "take medicine on time can get family's praise", and "among the people that I know there are patients who die of myocardial infarction". The partial regression coefficients were 0.245, 0.251, 0.248, 0.099, 0.234, 0.162, 0.095, respectively; while "worry about side effects of the drugs", "can't afford the medicine", the partial regression coefficients were -0.164 and -0.114. ConclusionHealth belief model is helpful for general practitioners to evaluate the effect factors of medication compliance on stable angina pectoris.
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.
ObjectiveTo observe the effect of health education on hand, foot and mouth disease knowledge of the parents and their psychological status, in order to provide a reference for regulating clinical intervention measures. MethodsBetween October 2011 and February 2013, self-made questionnaire was used to survey the parents of 286 children with hand, foot and mouth disease for their knowledge about the disease. We promoted health education including distributing pamphlets, holding lectures, and carrying out psychological counseling. Then, parents' knowledge and their psychological status were compared before and after the implementation of health education. ResultsAfter health education, parents' suspicion, anxiety, fear, indulgence in children and other negative psychological scores were significantly lower than those before intervention (P<0.05). Their knowledge on the disease was also significantly enhanced (P<0.05). Gender, age and educational background were the main influence factors for health education. ConclusionMulti-form comprehensive health education can enhance parents' knowledge on hand, foot and mouth disease effectively and alleviate various negative psychological situations, which assists them to participate in the treatment work actively, thus greatly promotes early rehabilitation of the child patients.
ObjectiveTo explore the risk factors of intraabdominal complications (IACs), pancreatic fistula (PF), and operative death after pancreatoduodenectomy (PD), and to provide a theoretical basis in reducing the rates of them. MethodsClinical data of 78 patients who underwent standard PD surgery in The Third People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from Jun. 2003 to Nov. 2011 were collected to analyze the influence factors of IACs, PF, and operative death. ResultsThere were 29 cases suffered IACs (13 cases of PF included), and 6 case died during 1 month after operation. Univariate analysis results showed that IACs and PF occurred more often in patients with soft friable pancreas, diameter of main pancreatic duct less than 3 mm, preoperative biliary drainage, no pancreatic duct stenting, and without employment of somatostatin (P < 0.05), no influence factor was found to be related to operative death. Multivariate analysis results showed that patients with no pancreatic duct stenting (OR=1.867, P=0.000), soft texture of remnant stump (OR=1.356, P=0.046), and diameter of main pancreatic duct less than 3 mm (OR=2.874, P=0.015) suffered more IACs; PF was more frequent in patient with no pancreatic duct stenting (OR=1.672, P=0.030), soft texture of remnant stump (OR=1.946, P=0.042), and diameter of main pancreatic duct less than 3 mm (OR=1.782, P=0.002);no independent factor was found to have relationship with operative death. ConclusionsSoft texture of remnant stump, diameter of main pancreatic duct less than 3 mm, and no pancreatic duct stenting are independent risk factors that should be considered in indications for PD surgery.
ObjectiveTo explore the influence factors of the surgical effectiveness for solitary enchondroma of the hand with pathologic fracture. MethodsA retrospective analysis was made on the clinical data of 65 patients with solitary enchondroma of the hand with pathologic fracture who were treated with operation and were accorded with selective standard between March 2010 and June 2013.There were 26 males and 39 females,aged 17 to 63 years (mean,36 years).The left hands were involved in 32 cases and the right hands in 33 cases.The tumor located at the metacarpus in 18 cases,and at the phalanx in 47 cases (at the proximal phalanx in 30 cases,at the middle phalanx in 9 cases,and at the distal phalanx in 8 cases).The duration from fracture to operation was 2 days to 2 years (mean,56 days).The operative methods were curettage and bone grafting.The ratios of the total active range of motion (ROM) of the metacarpophalangeal joint and interphalangeal joint between ipsilateral and contralateral fingers were used to evaluate the ipsilateral fingers'function.The time of returning to work was recorded.The multiple linear regressions were performed to analyze the risk factors of the effectiveness. ResultsA total of 65 cases were followed up 5-44 months (mean,24 months).All incisions achieved primary healing.No infection,re-fracture,or recurrence occurred.The X-ray films showed fracture healing,the healing time was 5-10 weeks (mean,6.5 weeks).All the bone grafts healed well.At last follow-up,the ROM ratio of the fingers was 0.46-1.00(mean,0.90).The time of returning to work was 92-180 days (mean,130 days).Multiple linear regressions showed that internal fixation was risk factor for the ROM ratio of the fingers (P=0.013).The duration from fracture to operation,internal fixation,and the tumor site were risk factors for the time of returning to work (P<0.05). ConclusionTo obtain good effectiveness for patients with solitary enchondroma of the hand with pathologic fracture,it is suggested that immediate operative treatment including tumor curettage,open reduction,and internal fixation with plate and screws of the fracture.
