Objective To study the effects of the multi-model analgesia for the old patients who received total hip replacement surgery.Methods Thiry-four patients who would received total hip replacement surgery were randomly divided into 2 group:Group E was the epidural analgesia group and Group M was the multi-model analgesia group.15min before the end of surgery,the load doses were given to the patients in both groups and the electric pumps for postoperative analgesia were connected.The multi-model analgesia was used for Group M:30min before the end of surgery,ropivacaine 7.5mg and morphine 1mg were given via epidural catheter,and at the end of surgery the catheter was pulled out.Intravenous analgesic pumb were used for Group M.Record the following data at different time point (T1 to T5):(1)the pain scores.(2)the scores of sedation and HR,MAP,RR and SpO2.(3)the numbers of the patients who suffered from adverse effects,such as nausea and vomiting and the numbers of patients who needed the rescue medicine were recorded in 48h after surgery.Results Compared to Group E,the scores of pain when the patients turned over in Group M,were lower significantly at T2.At T1 and T2 time point,the sedation scores of Group M were higher than those of Group E significantly.There was significant difference in the SpO2 change between groups at T1.Conclusion The multi-model analgesia of using long-acting local anesthetics and opioids for epidural analgesia once,then using sufentanil and tramadal for intravenous analgesia continuously,was safe and sufficient for the old patients.

Objective To observe the effect of 3R therapy on quality of life and subjective well-being in older patients with mild cognitive impairment (MCI). Methods 158 patients with MCI were collected from 8 communities in Ningbo city with Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV as the diagnostic criteria, and assessed by Montreal Cognitive Assessment (MoCA). The experimental group (n=79) was intervened by 3R (Reminiscence, Reality Orientation, Remotivation) for 12 weeks, and the control group (n=79) received no intervention. Their quality of life was assessed with WHO Quality of Life-BREF (WHOQOL-BREF) and the subjective well-being was assessed with Philadelphia Geriatric Center Morale Scale (PGC). Results Their quality of life and subjective well-being improved after intervention in the experimental group (P<0.05), and were better in the experimental group than in the control group (P<0.05). Conclusion 3R therapy could effectively improve the quality of life and subjective well-being in patients with MCI.

In aged patients, acute kidney injury (AKI) is a common clinical complication after percutaneous coronary intervention (PCI), highlighting the need for timely and certain diagnosis of this disease. A single centre, nested case-control study was conducted, which assessed the usefulness of urinary liver-type fatty acid-binding protein (uL-FABP), neutrophil gelatinase-associated lipocalin (uNGAL), and kidney injury molecule-1 (uKIM-1) for early detection of AKI. One hundred and thirty-two patients at or over 60 years old undergoing PCI were included. Serum creatinine (SCr) was measured before PCI, 24 and 48 h after PCI; uL-FABP, uNGAL, and uKIM-1 were measured before PCI, 6, 24, and 48 h after PCI. We identified 16 AKI patients and selected 32 control patients matched by admission time (<1 week), age (±5 years), and gender. In the receiver operating characteristic (ROC) curve analysis, the areas under the curve (AUCs) for the relative measurements of uL-FABP, uNGAL, and uKIM-1 were 0.809, 0.867, and 0.512 at 6 h after PCI, and 0.888, 0.840, and 0.676 at 24 h after PCI, respectively. AUC for the combination of uL-FABP and uNGAL was 0.899 at 6 h after PCI, and 0.917 at 24 h after PCI. Thus, measurement of uL-FABP and uNGAL levels at 6 and 24 h after PCI may be useful in detecting AKI in aged patients. Measurement of uKIM-1 levels provides inferior predictive power for early diagnosis of AKI.

【Objective】 To explore the predictive value of preoperative liver function for massive blood transfusion (MBT) in patients undergoing ascending aorta surgery. 【Methods】 Data from 238 patients undergoing ascending aorta surgery in the Department of Cardiovascular Surgery at The Affiliated Lihuili Hospital of Ningbo University were collected. Preoperative liver function tests were performed for all patients. Based on the perioperative transfusion volumes of red blood cell suspension, patients were divided into the MBT group, non-MBT group, and no blood transfusion (NBT) group. Clinical data during the perioperative period were compared among different groups. Receiver operating characteristic curve (ROC curve) analysis was used to assess the predictive value of liver function indicators for MBT and determine cut-off values. 【Results】 Compared with the non-MBT group and NBT group, the MBT group showed statistically significant differences in preoperative levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), direct bilirubin (DBIL), and serum albumin (SA) (P<0.05). ROC curve analysis revealed that AST had the largest area under the curve (AUC) for predicting MBT, with a value of 0.723. ALT had the highest specificity for predicting MBT at 86.7%, and SA had the highest sensitivity at 89.7%. When AST >28.50 U/L, ALT >40.00 U/L, SA ≤34.55 g/L, and DBIL >4.25 μmol/L, there was a significant increase in the transfusion volume of various blood components and the incidence of MBT. 【Conclusion】 Preoperative liver function indicators (AST, ALT, SA, DBIL) have a moderate predictive value for MBT in patients undergoing ascending aorta surgery.

Objective: To compare the clinical efficacy of posterior atlantoaxial screw-rod fixation combined with spinous process muscle-vessel complex bone graft or iliac bone graft for atlantoaxial instability. Methods: A retrospective case-control study was conducted to analyze the clinical data of 56 patients with atlantoaxial instability admitted to the Sixth Hospital of Ningbo from September 2014 to October 2016. There were 35 males and 21 females, with the age range from 9 to 59 years [(50.3±3.2)years]. A total of 26 patients were treated with posterior atlantoaxial screw-rod fixation combined with spinous process muscle-vessel complex bone graft (complex group), while 30 patients were treated with iliac bone graft (ilium group). Patients showed different degrees of neck pain and limited neck activity preoperatively. X-ray films and three-dimensional CT examination of the cervical spine were taken before and after operation for evaluating the atlantoaxial reduction, bone graft fusion and internal fixation. The operation time, intraoperative bleeding, bone fusion time, visual analogue scale (VAS), Japanese Orthopaedic Association (JOA) score, atlantodental interval (ADI) and axial symptoms were compared between the two groups, and the complications were recorded. Results: Both groups were followed up for 24-30 months, with an average of 27.4 months. In the complex group and the ilium group, the operation time was (2.21±0.25)hours and (2.72±0.26)hours (P<0.01); the intraoperative blood loss was (227.3±45.4)ml and (277.7±43.4)ml, respectively (P<0.05); the bone fusion time was (6.9±0.5)months and (8.1±1.8)months (P>0.05), respectively. In the complex group, the VAS was (5.45±0.69)points before operation, (2.64±0.51)points at the follow-up one month after operation, (0.91±0.7)points at the follow-up 12 months after operation, and (0.45±0.16)points at the follow-up 24 months after operation; and in the ilium group, the VAS was (5.18±0.75)points, (2.45±0.52)points, (1.27±0.19)points and (0.41±0.18)points correspondingly. In terms of VAS, there were significant differences before and after operation within each group (P<0.01), while there were no significant differences between the two groups at different time points (P>0.05). In the complex group, the JOA score was (10.82±0.35)points before operation, (12.73±0.65)points at the follow-up one month after operation, (15.18±0.61)points at the follow-up 12 months after operation, and (15.64±0.15)points at the follow-up 24 months after operation; and in the ilium group, the JOA score was (10.73±1.19)points, (13.01±0.63)points, (14.73±0.91)points and (15.55±0.51)points correspondingly. In terms of JOA score, there were significant differences between before and after operation within each group (P<0.01), while there were no significant differences between the two groups at different time points (P>0.05). In the complex group, the ADI was (2.28±0.59)mm before operation, (1.83±0.56)mm at the follow-up one month after operation, (1.71±0.56)mm at the follow-up 12 months after operation, and (1.59±0.67)mm at the follow-up 24 months after operation; and in the ilium group, the ADI was (2.23±0.60)mm, (1.80±0.18)mm, (1.67±0.69)mm and (1.62±0.53)mm correspondingly. In terms of ADI, there were significant differences between before and after operation within each group (P<0.01), while there were no significant differences between the two groups at different time points (P>0.05). The axial symptom scores were graded as excellent in 23 patients and good in three patients of the complex group while excellent in 21 patients and good in nine patients in the ilium group (P>0.05). There were no patients with spinal nerve injury caused by pedicle screw placement after operation. One patient in the ilium group had incision errhysis and recovered after dressing change, and other patients had no incision infection. Conclusions For atlantoaxial instability, posterior atlantoaxial screw-rod fixation combined with spinous process muscle-vessel complex bone graft or autogenous iliac bone graft can both achieve satisfactory clinical results. The spinous process-muscle-vascellum complex graft has less operation time and intraoperative bleeding than the autogenous iliac bone graft, which can be a feasible alternative operation.

OBJECTIVETo determine the detection rate and distribution characteristics of colorectal adenomas in Ningbo area of China, and to identify the risk factors for colorectal adenoma, in order to provide reference for colorectal cancer screening.

METHODSA cross-sectional study was performed among 8660 subjects undergoing colonoscopy in the Ningbo No.2 Hospital between January and December 2016, using a questionnaire, including demographic data (age, gender, height and weight), history of diseases (diabetes, hypertension, hyperlipidemia, and family history of malignant neoplasm), lifestyle (smoking, alcohol, dietary bias on red meat, dietary bias on fruit and vegetables, dietary frequency of pickled food and physical activities), and intestinal early warning symptoms. All colonoscopically detected polyps were removed for histological examination. Polyps were histologically divided into non-adenomatous (hyperplastic polyps and inflammatory polyps) and adenomatous polyps (tubular, villous, tubulovillous and serrated adenomas). Pathologic features were analyzed according to anatomical site. Multivariate logistic regression analysis was used to identify the risk factors for colorectal adenoma.

RESULTSA total of 7077 subjects who received colonoscopic examination and completed the questionnaire survey were enrolled in this study. There were 3633 males and 3444 females with a median age of 53 (ranged 17 to 83) years. Adenoma detection rate was 15.6% (1103/7077) in all cases, 21.0%(762/3633) for males, and 9.9%(341/3444) for females(P=0.000). Detection rate of 6.2%(29/469) was recorded in individuals aged less than 30 years, 8.0%(87/1086) in those from 30 to 39 years, 12.1%(148/1222) in those from 40 to 49 years, 16.8%(272/1623) in those from 50 to 59 years, 20.4%(326/1601) in those from 60 to 69 years, and 22.4%(241/1076) in those ≥70 years. The detection rate increased according to age(P=0.000). A total of 1521 adenomas were detected in 1103 cases, including 1455 tubular adenomas, 33 tubulovillous adenomas, 9 villous adenomas and 24 serrated adenomas. Among 1521 adenomas, 44.1%(n=671) located in the right hemicolon, 39.0%(n=593) in the left hemicolon, and 16.9%(n=257) in the rectum. Significantly larger number of serrated adenomas and advanced adenomas (advanced adenoma was defined as any adenoma with high-grade intraepithelial neoplasia, diameter ≥10 mm or with villous component) was observed in the right hemicolon compared to left hemicolon and rectum [serrated adenomas: 2.5%(17/671) vs. 0.8% (5/593) and 0.8% (2/257), P=0.029; advanced adenoma: 9.2% (62/671) vs. 5.2% (31/953) and 6.6% (17/257), P=0.021]. Multivariate analysis showed that malely (P=0.003), elderly (P=0.000), obesity (P=0.014), smoking (P=0.001), alcohol (P=0.032), and family history of malignancy (P=0.000) were independent risk factors of colorectal adenoma.

CONCLUSIONSIn view of a higher detection rate of colorectal adenoma in population aged 40 to 49 years especially in male individuals, the starting age of colonoscopy screening may be advanced to 40 years old. People with family history of malignancy, obesity, and habit of smoking or drinking should be regarded as important subjects for colonoscopy screening. During colonoscopy screening, special emphasis should be given to right hemicolon.

Objective: To explore the correlation of genetic mutations and clinical features of myelodysplastic syndromes (MDS) with scores of Revised International Prognostic Scoring System (IPSS-R). Methods: Eighty-seven patients with de novo MDS were enrolled. Mutations of MDS-related genes and clinical features were used to determine the incidence and subtype of mutations. Clinical features and IPSS-R scores of the patients with high frequency mutations involving TET2, TP53, ASXL1, RUNX1 and SF3B1 genes were compared. Results: Fifty-four patients (62.1%) harbored at least one point mutation. The incidences of various mutations were significantly different, with the incidence of MDS-EB-2 being 100% and MDS-SLD being only 38.9%. Compared with the wild types, patients harboring mutations had higher lactate dehydrogenase, higher β2 microglobulin, higher percentage of bone marrow blast cells and lower hemoglobin levels (P=0.027, <0.01, <0.01, 0.046, respectively). The IPSS-R scores of MDS patients with mutations were significantly higher than the wild types (P<0.01). The IPSS-R scores of the TP53 mutation groups were 7.82±1.83, which was significantly higher than the control group (3.77±1.66, P<0.01). No difference was found between the IPSS-R between patients carrying TET2, ASXL1, RUNX1, and SF3B1 mutations or the wild types (P>0.05). Conclusion Genetic mutations are commonly found in MDS. MDS patients with mutations have unique clinical laboratory characteristics. Although the prognostic value of most genes is controversial, TP53 is an definite indicator of poor prognosis.

OBJECTIVETo compare the stability of subaxial cervical anterior transpedicular screw(ATPS) fixation and three traditional fixations for three-column injury.

METHODSSix specimens of cervical spine were prepared. After measurememt of the range of motion(ROM) in intact state, the specimens were made into three-column injury models. The models were reconstructed with an anterior cervical cage, and stabilized by ATPS, anterior plate(AP), anterior plate + lateral mass screw(AP+LMS) and posterior transpedicular screw(PTPS). The ROM of the models in the four states were measured, and the results of data were compared after standardization.

RESULTSThe normalized ROM of ATPS state in flexion-extension, lateral bending, axial rotation were(77.17±4.75)%, (82.00±2.61)%, (83.17±2.23)%, which were significant small than those in intact state(<0.05). The normalized ROM of AP state in flexion-extension, lateral bending, axial rotation were(119.67±7.42)%, (116.33±7.53)%, (112.67±5.99)% , which were significant larger than those in intact state(<0.05). The normalized ROM of AP in all directions were significant larger than those of ATPS(<0.05). There was no significant difference between normalized ROM of PTPS state and those of ATPS state in flexion-extension and lateral bending(>0.05). The normalized ROM of PTPS state in axial rotation was(6.83±2.48)% and was significant larger than that of ATPS state(=0.009). The normalized ROM of AP+LMS state in flexion-extension was(68.50±2.43)%, which was significant smaller than that of ATPS state(=0.003). There was no significant difference between the normalized ROM of AP+LMS state and those of ATPS state in lateral bending and axial rotation(>0.05).

CONCLUSIONSSubaxial cervical three-column injury model reconstruction by ATPS can provide the adequate primary stability, of which biomechanics property is superior compared to AP and PTPS, and is similar to that of AP+LMS. It can be applied to the patients with no need to decompression and reduction through posterior approach.

Astragaloside Ⅳ(AS-Ⅳ) has protective effects against ischemia-reperfusion injury(IRI), but its mechanism of action has not yet been determined. This study aims to investigate the protective effects and mechanism of AS-Ⅳ on H9c2 cardiomyocyte injury induced by hypoxia-reoxygenation(H/R). The H/R model of myocardial cells was established by hypoxic culture for 12 hours and then reoxygenation culture for 8 hours. After AS-Ⅳ treatment, cell viability, the reactive oxygen species(ROS) levels, as well as the content or activity of superoxide dismutase(SOD), malondialdehyde(MDA), interleukin 6(IL-6), and tumor necrosis factor alpha(TNF-α), were measured to evaluate the effect of AS-Ⅳ treatment. The effect of AS-Ⅳ on HO-1 protein expression and nuclear Nrf2 and Bach1 protein expression was determined by Western blot. Finally, siRNA was used to knock down HO-1 gene expression to observe its reversal effect on AS-Ⅳ intervention. The results showed that as compared with the H/R model group, the cell viability was significantly increased(P<0.01), ROS level in the cells, MDA, hs-CRP and TNF-α in cell supernatant and nuclear protein Bach1 expression in the cells were significantly decreased(P<0.01), while SOD content, HO-1 protein expression in cells and expression of nuclear protein Nrf2 were significantly increased(P<0.01) in H/R+AS-Ⅳ group. However, pre-transfection of HO-1 siRNA into H9c2 cells by liposome could partly reverse the above effects of AS-Ⅳ after knocking down the expression of HO-1. This study suggests that AS-Ⅳ has significant protective effect on H/R injury of H9c2 cardiomyocytes, and Nrf2/Bach1/HO-1 signaling pathway may be a key signaling pathway for the effect.

Objective:To explore the effect of vocal training based on International Classification of Functioning, Disability and Health (ICF) and International Classification of Health Interventions (ICHI) on vocal function after vocal cord polyps. Methods:A framework of rehabilitation was developed with joint use of ICF and ICHI. From January, 2017 to December, 2018, 30 patients with vocal cord polyps and vocal dysfunction post operation were sampled. They accepted the therapy for a month, and assessed with Grade, Roughness, Breathiness, Asthenia and Strain scale (GRBAS), and measured acoustic parameters before and after operation, and after training, respectively. Results:The scores of GRBAS decreased after training, compared with those both before and after operation (F > 6.214, P < 0.05), as well as the acoustic parameters of fundamental frequency, fundamental frequency perturbation, normalized noise energy and amplitude perturbation (F > 9.655, P < 0.05). Conclusion:Vocal training based on ICF and ICHI is effective on vocal function after operation for vocal cord polyps.
