Objective:To investigate parents′ knowledge and attitude toward post-operative pain management in pediatric orthopedics and analyze influencing factors.Methods:A total of 170 parents of 6 to 16 years old children who underwent selective surgeries and were hospitalized because of limb fracture were conveniently selected in Children′s Hospital of Soochow University from April to December in 2019, They were investigated using the general data questionnaire, Pain Management Knowledge and Attitudes Questionnaire.Results:There were 167 parents completed questionnaires in our study. The mean score of parents′ knowledge, general attitude and negative attitude to pain medication were 15.0(3.00), 24.0(4.00) and 17.0(3.00) respectively. There were statistical differences between different educational levels of parents′ knowledge ( χ2 value was11.599, P=0.021), as well as different age of parent′s general attitude ( χ2 value was 7.053, P=0.029). Spearman-related results showed that parents′ cognition was positively correlated with general attitudes ( r value was 0.394, P<0.01). Conclusions:The majority of parents are at moderate to high level of knowledge, general attitude and negative attitude to pain medication. Pediatric nurses should pay more attention to parents′ knowledge deficit of and negative attitude toward pain assessment tools and pain-drugs to develop targeted educational intervention programs for promoting parental involvement.

Background and purpose:Along with the development of diagnosis and treatment technology, the disease free survival and overall survival of breast cancer have been extended. In order to improve the quality of life after mastectomy, more and more breast reconstructions were applied in breast cancer patients. We retrospectively reviewed 118 cases of free abdominal lfaps for breast reconstruction performed in Fudan University Shanghai Cancer Center. Clinical outcomes, reconstructive techniques and experiences are discussed. Methods:From November, 2006 to June, 2013, we used free abdominal lfaps to perform 118 cases of breast reconstruction on 117 female patients after mastectomy. We observed the surgery, complications and safety of this technic. Results:We performed 118 cases of lfaps based on deep inferior epigastric vessels. The average operation time was 7.72 h. The average time of ischemia was 78.74min. The average anastomosis time was 60.83min. The average number of perforators included in the lfap was 3. The internal thoracic vessels were preferred recipient vessels. Ten cases of vessel crisis occurred and 6 of them were venous thrombosis and 4 cases were venous kink. Seven of them were salvaged, and the other 3 failed, the success rate was 97.46%. Postoperative infection rate was 7.00%. Abdominal bulge occurred in 3.50%of patients. None of the patients developed abdominal hernia. The median interval between surgery and the ifrst cycle of adjuvant chemotherapy was 19 days. The median follow-up time was 12 months. One case of distant metastasis, but no local recurrence was observed. Conclusion: Although free abdominal flap breast reconstruction requires complicated microsurgical techniques, and the learning curve does exist, free abdominal lfap breast reconstruction has a high success rate with oncological safety and few complications.

Objective:To investigate the risk factors of postoperative continuous renal replacement therapy application in Stanford type A acute aortic dissection.Methods:This retrospective study included 527 patients with Stanford type A acute aortic dissection from November 2015 to February 2018 in Beijing Anzhen Hospital. They were divided into 2 groups according to whether or not needed postoperative continuous renal replacement therapy, group CRRT(78 cases) and group None CRRT(449 cases). Binary logistic regression analysis was used to analyze the risk factors of continuous renal replacement therapy. Results:Of all the patients, the percentage of using continuous renal replacement therapy was 14.8%(78/527), and the mortality of 30 days after surgery was 8.5%(45/527). The independent risk factors associated with CRRT were preoperative serum creatinine(sCr)( OR=1.012, 95% CI: 1.005-1.019, P<0.001), transfusion of red blood cell in surgery( OR=1.141, 95% CI: 1.071-1.216, P<0.001), transfusion of platelet in surgery( OR=1.307, 95% CI: 1.084-1.576, P=0.005), the total amount of drainage( OR=1.000, 95% CI: 1.000-1.000, P=0.036), and the time of extubation after surgery( OR=1.004, 95% CI: 1.001-1.008, P=0.013). Conclusion:The risk factors of CRRT after emergency surgery of Stanford type A acute aortic dissection are preoperative serum creatinine, transfusion of red blood cell in surgery, transfusion of platelet in surgery, the total amount of drainage and the time of tracheal extubation after surgery. We need to focus on those risk factors in our daily job and manage them timely and properly, in order to improve patients’ prognosis.

Objective:To investigate the relationship of glycated hemoglobin(HbA1c)and brain natriuretic peptide(BNP)levels with clinical prognosis of acute myocardial infarction.Methods:A total of 108 patients with acute myocardial infarction combined with diabetes mellitus, who underwent percutaneous coronary intervention(PCI)from March 2016 to June 2017 in our hospital, were enrolled.According to the HbA1c level, patients were divided into three groups: Group A(HbA1c≤6.9%, n=36), Group B(7%≤HbA1c≤7.9%, n=31)and Group C(HbA1c≥8%, n=41). HbA1c and NT-proBNP levels, cardiac function classification at admission and discharge, the incidence of adverse cardiac events during hospitalization and left ventricular ejection fraction(LVEF)at admission, discharge and 3 months after discharge were analyzed.Results:Among the three groups, plasma NT-proBNP levels were higher in Group C than in Group B and Group A( P<0.05), and there was no significant difference between Group B and Group C( P<0.05). Furthermore, HbA1c levels were positively correlated with NT-proBNP levels in Group C( P<0.05). Cardiac function grading was better in Group A and Group B than in Group C at discharge.During hospitalization, the incidence of adverse cardiac events in Group C was 29.3%, which was higher than in Group A(8.3%)and Group B(9.7%)( P<0.05). LVEF levels were significantly improved in Group A and Group B at discharge and 3 months after discharge, compared with those at admission, while Group C had no significant improvement in LVEF levels and had lower LVEF than Group A and Group B( P<0.05). Conclusions:HbA1c and NT proBNP levels can be used as a joint monitoring indicator in patients with acute myocardial infarctions after PCI, to help prevent and reduce the incidence of complications and mortality in patients with acute myocardial infarction after PCI and improve clinical prognosis.

Objective:To evaluate the 3-year survival outcomes and late injury between the self-designed patent single-channel applicator, which was modified from the traditional tandem applicator and wrapped with a oval-shield alloy around the source channel and standard Fletcher-type applicator in the high-dose-rate brachytherapy for cervical cancer.Methods:Patients initially diagnosed with cervical cancer in the Affiliated Hospital of Southwest Medical University from December 2011 to April 2017 were enrolled and randomly assigned into the external beam radiotherapy (EBRT)+ single-channel intracavitary applicator group (the patent single-channel group) and EBRT+ the Fletcher applicator group. The whole pelvis irradiation was delivered with 6-MV photons via a four-field box variant or anterior and posterior parallel fields. Five to six fractions of intracavitary brachytherapy were performed at a dose of 7 Gy at point A once a week after 30 Gy (Equivalent Dose in 2 Gy at point A: 80-90 Gy). Chemotherapy was given with intravenous injection of cisplatin at a dose of 40 mg/m 2 once weekly during EBRT. Clinical efficacy and safety were evaluated after corresponding treatment. Results:In total, 150 eligible cases were assigned into the Fletcher applicator group and 149 cases into the patent single-channel group. Up to December 2020, all patients had been followed up for 3 years, and the median duration of follow-up was 61 months. In the Fletcher group, the 3-year overall survival, progression-free survival and locoregional failure-free survival was 76.3%, 78.1% and 75.4%, and 83.8%, 80.3% and 85.5% in the single-channel group, respectively. In the Fletcher group, the cumulative rate of grade 3-4 late rectal complications was 3.3% and 6.7% in the single-channel group ( P=0.122). The cumulative rate of grade 3-4 bladder complications was 1.3% in the Fletcher group and 0.7% in the single-channel group ( P=1.000). Conclusion:The self-designed patent single-channel intracavitary applicator yields equivalent long-term clinical efficacy and safety to the standard Fletcher-type three-channel applicator in the HDR brachytherapy for uterine cervical cancer.

Objective:To investigate whether the antibacterial copper sulfide (CuS)/graphene oxide (GO) nanosheets composite film can promote angiogenesis and osteogenesis in vitro. Methods:GO and CuS/GO nanosheets were synthesized and mixed into polyvinyl alcohol (PVA)/carboxymethyl cellulose (CMC) hydrogel films. The study was conducted in 4 groups: PVA/CMC/GO, PVA/CMC/CuS/GO, PVA/CMC (only PVA/CMC-based film) and blank control (no material). The PVA/CMC, PVA/CMC/GO and PVA/CMC/CuS/GO films were characterized by electron scanning microscopy and energy dispersive spectrometer. The biocompatibility of different films (PVA/CMC/CuS/GO films with concentrations of CuS/GO nanotablets of 0, 50, 100, 200, 400, and 800 μ g/mL) was evaluated by CCK-8, live/dead cell staining, and hemolysis test. The angiogenesis was evaluated by cell migration and tube forming test in vitro. Alkaline phosphatase and alizarin red staining were used to evaluate osteogenesis in vitro, and the expression of osteogenic genes was measured by immunofluorescence staining and RT-qPCR. In addition, the bacterial plate counting method and bacteriostatic circle method were used to evaluate the antibacterial activity of films. Results:In the PVA/CMC/GO and PVA/CMC/CuS/GO groups, the surface of the PVA/CMC-based film was smooth and flat whereas the nanosheets composite films were irregularly flaky and convex. The biosafety experiments showed that the PVA/CMC-based film composited with GO or CuS/GO nanosheets at the concentration of 100 μg/mL had good biocompatibility. The results of angiogenesis in vitro showed that the migration ratio of HUVEC cells in the PVA/CMC/CuS/GO group was significantly better than those in the PVA/CMC/GO, PVA/CMC and control groups ( P<0.001). In the experiment of tube forming area and length, the PVA/CMC/CuS/GO group was significantly better than the PVA/CMC/GO, PVA/CMC and control groups ( P<0.001). The osteogenic differentiation in vitro displayed that the alkaline phosphatase and alizarin red staining of MC3T3-E1 cells in the PVA/CMC/CuS/GO group were significantly better than those in the PVA/CMC/GO, PVA/CMC and control groups ( P<0.001). In addition, the fluorescence intensity of immunofluorescence staining in alkaline phosphatase and type Ⅰcollagen on MC3T3-E1 cells, and the mRNA expression levels of osteogenic related genes including alkaline phosphatase, bone morphogenetic protein 2, osteocalcin and osteopontin in the PVA/CMC/CuS/GO group were significantly higher than those in the PVA/CMC/GO, PVA/CMC and control groups ( P<0.001). The antibacterial assay showed that the PVA/CMC/CuS/GO group had a significantly greater antibacterial activity and a significantly larger inhibition zone against Gram-positive bacteria and Gram-negative bacteria than the PVA/CMC/GO, PVA/CMC and control groups ( P< 0.001). Conclusions:PVA/CMC films composited with GO or CuS/GO nanosheets demonstrate ideal biocompatibility and antibacterial properties which promote angiogenesis and osteogenic differentiation in vitro. In particular, antibacterial PVA/CMC/CuS/GO composite films with the coupling function of angiogenesis and osteogenesis are expected to provide a new strategy for infectious bone defects.

OBJECTIVETo explore the clinicopathological characteristics, efficacy, and prognostic factors for patients with rectal gastrointestinal stromal tumor(GIST).
METHODSClinicopathological and follow-up data of 61 patients with rectal GIST in our department from January 1990 to October 2012 were analyzed retrospectively and pathology specimens were reviewed. Kaplan-Meier method was used to calculate the survival. Univariate analysis and multivariate analysis were performed to investigate the influencing factors of prognosis with Log-rank test and Cox regression model.
RESULTSThere were 42 male and 19 female patients with a median age of 59 years old. Eighteen cases(29.5%) were confirmed preoperatively as GIST by biopsy and 46 cases were diagnosed as GIST by first pathological examination. Fifteen cases(24.6%) were revised as GIST after re-examination of specimes among whom 14 cases had been diagnosed as leiomyoma or sarcoma, and 1 as neurolemmoma. Tumor location was above peritoneal reflection in 12 cases(19.7%) and below peritoneal reflection in 49(80.3%). Fifty-two patients underwent surgery, including 21 extended resections(lymph nodes clearance and combined organs resection simultaneously) and 31 local resections(tumor rejection or partial resection of rectal wall). Eleven patients received preoperative imatinib(400 mg/d). Forty-one cases received imatinib therapy after operation or biopsy diagnosis, including 25 cases who received palliative treatment for postoperative recurrence. Median follow-up time was 55(6 to 391) months and follow-up longer than 2 years was carried out in 46 patients. Overall survival rates of 1-, 2-, 3- , 5-year were 98%, 95.6%, 86.0% and 73.7% respectively. There were no significant differences between local resection group(96.4%, 92%, 83.3% and 77.3%) and extended resection group (100%, 94.7%, 89.50% and 82.6%)(χ(2)=0.004, P=0.947). Univariate analysis showed that survival was only associated with recurrence and metastasis (χ(2)=4.292, P=0.038). Multivariate Cox analysis showed postoperative survival was not associated with any factors(all P>0.05). The 3-year survival rate of patients with postoperative recurrence or metastasis receiving imatinib therapy was better as compared to those who did not received imatinib(82.7% vs. 71.4%).
CONCLUSIONSRectal GIST are more common in the lower rectum. Surgery is the main treatment for rectal GIST. Local complete resection is the mainstay treatment. Extensive resection and lymph node clearance may not improve survival. Imatinib can improve the prognosis of patients with recurrence or metastasis.

OBJECTIVETo explore the current trends of breast reconstruction (BR) for breast cancer patients in China.
METHODSA questionnaire was designed for this study, and it included questions on surgeon demographics, number of mastectomy and BR, type and timing of BR, reconstructive choices in the setting of preoperative or postoperative radiotherapy or chemotherapy, etc. All data were collected until December 2012. Questionnaires were sent to 52 members of the Committee of Breast Cancer Society by e-mail or mail.
RESULTSBy July 2013, 41 questionnaires had been returned. Among all, 5 were excluded for not performing BR. These 36 hospitals covered 22 provinces and municipalities in China. A total of 538 surgeons working in the general surgery or oncological surgery department, but only 123 (22.9%) were qualified to perform BR. In 2012, except for 4 missing data, 24, 763 mastectomies were performed in 32 hospitals; among them, 1120 (4.5%) received BR. According to these 36 respondents, 32 (88.9%) performed prosthetic (1, 843 cases in all) while 4 (11.1%) performed prosthetic BR with acellular dermal matrix (17 cases in all) from the time of their first BR operation to the end of 2012. During the same period, 965 latissimus dorsi myocutaneous flaps with implant were performed in 23 (63.9%) hospitals while 738 latissimus dorsi myocutaneous flaps without implant were performed in 32 (88.9%) hospitals. At the same time, 366 pedicled transverse rectus abdominis myocutaneous flap BRs were performed in 28 (77.8%) hospitals, while 155 abdominal free flap BRs were carried out in 9 (25.0%) hospitals. The overall complication rate was 18.2%. Postoperative radiotherapy had some effect on influencing the esthetic outcomes of BR, so the autologous BR was recommended, but the timing remained controversial. Regarding chemotherapy, most respondents concluded that it had no effect or only a mild effect. The overall cosmetic outcomes of the reconstructed breasts satisfied the majority of physicians and patients.
CONCLUSIONSWith more attention paid to the quality of life after mastectomy, more and more BRs are needed, but the ratio is still low in China. To improve this situation, more efforts are needed, including the improvement of the intrahospital framework of multi-disciplinary service, the training for doctors and the educational program for patients, etc.
