BACKGROUND: Patients with osteoporotic compression fractures of the lumbar spine have varying degrees of changes in the sagittal parameters of the spine and pelvis, resulting in disequilibrium and rebalancing of the sagittal plane of the whole spine/lumbar spine. If the primary osteoporotic vertebral compression fracture is not treated promptly, it develops into an old osteoporotic vertebral compression fracture with nonunion over time. OBJECTIVE: To observe the effect of percutaneous vertebroplasty in nine patients with old osteoporotic lumbar compression fracture with nonunion. METHODS: A retrospective analysis was conducted on the clinical data of nine elderly patients with old osteoporotic lumbar compression fractures with nonunion treated in the Orthopedics Department of Shanghai Public Health Clinical Center from September 2018 to August 2022. All patients underwent revision treatment with percutaneous vertebroplasty and received regular anti-osteoporosis treatment and rehabilitation training. The lumbar spine X-ray plain film and three-dimensional CT test results were reviewed before discharge and during follow-up to evaluate the diffusion of bone cement. Visual analog scale score, lumbar Oswestry disability index score, and Roussouly classification were recorded before, after surgery and during follow-up. RESULTS AND CONCLUSION: (1) During postoperative follow-up, none of the 9 cases in this group experienced serious surgical complications such as nerve injury, infection, bone cement leakage, pulmonary embolism, and allergic shock, and no adverse reactions related to bone cement occurred. One patient died of respiratory failure due to COVID-19 infection 2 years after operation. (2) The visual analog scale score and Oswestry disability index score of postoperative pain in patients with recurrent vertebral fractures after percutaneous vertebroplasty were significantly lower than those before revision surgery. After the last follow-up percutaneous vertebroplasty revision surgery, the Roussouly classification of patients significantly improved. There was no statistically significant difference between the changes in vertebral body height during the last follow-up measurement and preoperative comparison. (3) These findings indicate that for patients with old osteoporotic lumbar compression fractures with nonunion, moderate injection of bone cement and effective dispersion of bone cement have a significant relieving effect on postoperative pain. Regular anti-osteoporosis and effective postoperative rehabilitation training can help patients improve their postoperative lumbar spine function. [ABSTRACT FROM AUTHOR]

In order to more fully exploit the effective information among multivariate load series and thus improve the prediction accuracy, a short-term load prediction model combining Bayesian optimization algorithm, long and short-term time series network with attention mechanism and error correction was proposed. First, the LSTNet-attention model based on Bayesian optimization was constructed for preliminary prediction, and the Bayesian algorithm was used to optimize multiple structural parameters of the model, reduce the randomness of manually set parameters, and reasonably assign feature weights through the attention mechanism. Then, an XGBoost error correction model based on Bayesian hyperparameter optimization was established to mine the potential, unused and effective information in the initial prediction error sequence, and make error prediction and correction, and then obtain the final prediction results. Through the empirical analysis using the real load data of a place in Australia, the experimental results show that the proposed prediction model has better prediction effect compared with other models, which provides a relevant reference for research work such as load prediction.

Since the 1930s, the new agricultural loan institutions of Shaanxi Provincial Bank began to be active in Shaanxi agricultural loan market. As a relatively modern agricultural financial system in Northwest China during the period of the Republic of China, it made important contributions to solving the difficulties of farmers’ capital turnover, making farmers get rid of the exploitation of usury, improving Shaanxi’s agricultural production conditions, reviving rural small handicraft and sideline, and representing the highest level of rural financial development of local banks in Northwest China in modern times. Compared with traditional lending organizations, the new agricultural loans carried out by Shaanxi Provincial Bank were more in line with the market environment at that time in terms of system construction and lending methods, and promoted the improvement and transformation of rural lending system and rural production concept, which had a positive impact on local economy and society.

Based on the complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) and temporal convolutional network-long short-term memory network(TCN-LSTM) hybrid model, a forecasting method was proposed for the problem that the short-term power load data are so stochastic that it is difficult to achieve accurate forecasting. Firstly, the proposed algorithm decomposed the load data into a number of relatively smooth subseries using the CEEMDAN algorithm. Secondly, in order to reduce the computational scale of the subsequent model, the series were recombined by using the permutation entropy algorithm. Then, the individual recombinant series were input into the TCN-LSTM hybrid model,and the TCN model was used to extract features and construct feature vectors of the series, which were then trained and predicted based on the LSTM model. Finally, all the obtained predicted values were summed to obtain the complete predictive value of power load values. By using the real load data from a European site for validation, the results justify the higher prediction accuracy compared with other common prediction algorithms, which provides a relevant reference for research work such as load prediction.

Objective To analyze the effect of multidisciplinary team intervention under mind mapping on postoperative weakness and despair in patients with primary liver cancer. Methods A total of 170 patients who underwent primary liver cancer surgery in the Third Department of Hepatobiliary Surgery, the First Af-filiated Hospital of Hunan Normal University from June 2020 to June 2021 were selected as the research ob-jects, and randomly divided into the observation group and the control group, with 85 cases in each group. The control group received routine postoperative nursing, and the observation group received multidisciplinary team intervention under mind mapping. The degrees of weakness and despair level, nutritional status and post-operative complications were compared between the two groups. Results Before the intervention, there was no significant difference in the scores of degrees of weakness between the two groups(P >O. 05). After the in-tervention, the scores of health status, social support, self-control and emotion in the observation group were lower than those in the control group, and the differences were statistically significant(P 0. 05). After the intervention, the scores of losses of motivation, feeling of the future and expectation of future in the observation group were lower than those in the control group, and the differences were statistically significant (P0. 05). After intervention, the levels of BMI and serum protein in the observation group were higher the differences were statistically significant( P <0. 05). The incidence of complications in the observation group was lower than that in the control group, and the difference was statistically significant(P<0. 05). Conclusion Multidisciplinary team intervention under mind mapping can effectively reduce the postoperative weakness and despair level of patients with primary liver cancer, improve the nutritional status of patients and reduce the incidence of complications.
