The supramolecular inclusion properties of beta-cyclodextrin (beta-CD) and resveratrol (Res) were investigated using drug-protein interaction spectroscopy method. The differences between the results of interaction spectroscopy method and the results of classical method were compared. The total energy of the stable inclusion of cyclodextrin-resveratrol was calculated by Gaussian theory calculation. The stable inclusions in the process of interaction between resveratrol/inclusion complex and bovine lactgoferrin (BLF) were studied by molecular modeling. The results showed that the interaction spectroscopy method could explain the property of the inclusion in a more sensitive manner, it also interpreted the conveying mechanism of BLF binding with inclusion complex. The molecular modeling result showed consistent results with Gaussian theory calculation; both of the two methods obtained the stable configuration of beta-CD-Res inclusion. The relevant result provided an experimental consequence for the pharmacology research of beta-cyclodextrin-resveratrol inclusion complex as well as offering a new reference to the future research of supramolecular inclusion compound.

Objective:To explore the optimal postpartum nursing intervention method of elderly second-birth parturient based on the best evidence and evaluate its effect so as to improve the quality of clinical nursing.Methods:Based on the best evidence obtained from the previous study, the optimal nursing examination index of the elderly second parturient was established, and the evidence of best practice was obtained by using the evidence-based nursing method, and the 2017 revised version (the third edition of) Johns Hopkins evidence-based nursing practice model) was used to guide nurses to apply the evidence to clinical practice. During the period from March to May 2019, the baseline review was completed, including 82 pregnant women and 43 nurses. The evidence was incorporated into clinical practice in June 2019. From July to October 2019, the same indicators and inclusion and exclusion criteria were used to evaluate the effectiveness of evidence application in 43 nurses (including midwives) and 85 elderly second-child parturients in obstetric wards (including baby-friendly areas). The anxiety, depression, maternal satisfaction and nurses' correct implementation rate of the best evidence were compared before and after the application of evidence.Results:After the use of evidence-based intervention, the implementation rate of nurses was above 80%. The anxiety score of parturient decreased from 55.29±10.11 to 41.74±10.35, the difference was statistically significant ( t value was 8.55, P<0.001), and the depression score decreased from 57.77 ±8.32 to 47.86 ±9.33, the difference was statistically significant ( t value was 7.23, P<0.001). Maternal satisfaction increased from 92.68% (76/82) to 98.82% (84/85), the difference was statistically significant ( χ2 value was 3.92, P< 0.05). Conclusion:The result of practice shows that through evidence-based nursing intervention, we can further standardize the postpartum optimal nursing paradigm of elderly second-child parturients in China. Reduce postpartum anxiety and depression and improve maternal satisfaction. And quality review still needs to be continuously promoted and implemented in clinical practice in order to continuously improve the quality of nursing and ensure sustainability.

OBJECTIVE: To investigate the clinical effect of a modified arthroscopic outside-in suture technique in the treatment of meniscus tear using a spinal needle. METHODS: From January 2015 to October 2017, 95 patients treated with this method were followed-up. Among these cases, there were 36 males and 59 females. The age of the patients ranged from 16 to 77 years, (46.79±18.07) years in average. Among them, there were 28 patieats aged 16-35, 53 patients aged 36-65, and 14 patients aged over 65 years old. 28 cases were diagnosed with medial meniscus tear, 43 cases with lateral meniscus tear and 24 cases with both medial and lateral meniscus tear. Causes of the injury included sports, sprain, etc. According to Barrett standard, the clinical healing of meniscus tear was judged. Lysholm score, knee range of motion, visual simulation score (VAS) and magnetic resonance imaging (MRI) were used to evaluate the postoperative knee function and recovery of the patients. RESULTS: The 95 patients were followed up for 22 to 36 months, with an average of (28.32±3.98) months. According to Barrett standard, 90 patients (94.7%) obtained meniscus clinical healing. Meniscal healing rates were 96.43%, 96.23% and 85.71% in the three age groups, respectively. The meniscal healing rate was lower in the elderly group, but there was no significant difference in statistical results (P=0.262). Five patients had deep tenderness in the joint space of the injured side, and the overstretch test was positive. The preoperative and postoperative VAS scores, Lysholm scores and knee motion were compared in each group, and the differences were statistically significant (P < 0.01). At the end of the last follow-up, there were no cases of knee joint effusion, swelling and interlocking, and the joint function was effectively improved in most patients. No surgical site infection, periarticular vascular/nerve injury or knotting reaction was found during the follow-up. CONCLUSION This modified arthroscopic outside-in suture technique using a spinal needle has the characteristics of simple operation, small trauma and rapid recovery, and the mid-term follow-up results were satisfactory. Therefore, we consider this method to be a safe and efficient method for the treatment of meniscus anterior horn and body tear.

OBJECTIVE: To evaluate the surgical technique and clinical effect of less invasive intrame-dullary nail fixation combined with titanium cable cerclage in the treatment of subtrochanteric fractures. METHODS: A retrospective study was performed in 46 cases of subtrochanteric fractures in Peking University People's Hospital from January 2015 to December 2017. Among them, there were 14 males and 32 females, with an average age of (77.83±10.66) years (44-92 years); 17 cases on the left side and 29 cases on the right side. The causes of injury included crash from a height, traffic accident and accidental fall. According to Seinsheimer classification, there were 26 cases of type Ⅱ, 11 cases of type Ⅲ, 9 cases of type Ⅳ, and these cases were all closed injury. After admission, these patients underwent continuous tibial tuberosity bone traction to maintain the length and force line of the lower extremity, so as to reduce the difficulty of intraoperative fracture reduction. Anticoagulant therapy was given before operation to reduce perioperative thrombotic complications. All the patients were treated with less invasive intramedullary nail fixation combined with titanium cable cerclage. Operation time, blood loss during surgery, time of fracture healing were recorded, Harris and Sanders scoring system were used to assess hip function after operation at each follow-up time point. RESULTS: All the included patients underwent surgery successfully. Average operative time and intraoperative blood loss of these patients were (131.09 ± 20.06) min and (191.96±111.03) mL, respectively. All the patients were followed up satisfactorily, with an average follow-up time of 28 months. The fractures received bone healing within 3-6 months, average hospital stay was (10.61±2.85) days. The Sanders score was excellent in 3 cases, good in 37 cases and common in 6 cases, with an excellent and good rate of 86.96%. The Harris score was excellent in 6 cases, good in 36 cases, with an excellent and good rate of 91.30%. There were no cases of wound infection, loss of reduction, nonunion of fracture or internal fixation failure. Hip pain symptoms were effectively relieved in most patients. CONCLUSION Less invasive intramedullary nail fixation combined with titanium cable cerclage can obtain good alignment and stability of fracture ends, which is an effective method for the treatment of subtrochanteric fractures.
