[Objective] The aims of this study are to explore the spatial variation characteristics of soil respiration and the accuracy of soil respiration prediction with Kriging method, so as to provide data reference for accurate prediction of soil carbon budget in different terrestrial ecosystems. [Methods] The typical farmland, grassland and forestland in the northern part of the Huang-Huai-Hai Plain were selected as sample areas, and the co-Kriging method was used to predict soil respiration based on the auxiliary indicators of soil physical and chemical properties, so as to evaluate the accuracy of prediction with the common Kriging method. [Results] Soil respiration showed moderate variation in different land use patterns, and the coefficients of variation were 33% (farmland), 24% (grassland) and 31% (forest land), respectively. The correlation distances of soil respiration space in descending order were forest land (15.12 m), farmland (3.83 m) and grassland (2.47 m) . Based on correlation analysis and co-Kriging simulation, the optimal auxiliary indexes of soil respiration space variation were determined, which were carbon/P ratio (C/P), nitrogen/P ratio (N/P) and pH value in farmland. In addition to soil moisture (SM) and soil temperature (ST5), pH value and temperature (TEMP) were the unique auxiliary indexes of grassland and forestland. Soil respiration spatial variation prediction showed that the interpolation accuracy of the collaborative Kriging method was higher than that of the ordinary Kriging method, and the improvement was most obvious in the grassland. The mean absolute error (MAE), mean relative error (MRE), root mean square error (RMSE) and mean standard error (MSE) increased by 10.14%, 9.82%, 9.10% and 10.87%, respectively. The improvement of each error accuracy was between 4.78% (MAE) and 12.09% (MRE) in forestland, and the improvement of prediction accuracy was the smallest in farmland, and the prediction accuracy of collaborative Kriging method was only 3.27% higher than that of ordinary Kriging method. [Conclusion] The co-Kriging method with the influence factors of soil respiration as auxiliary variables can more accurately predict the spatial variation characteristics of soil respiration in forestland, farmland and grassland.

Objective: To analyze the value of serum lactate dehydrogenase in evaluating severe pneumonia in patients undergoing craniocerebral surgery. Methods: 268 patients undergoing selective craniocerebral surgery in our hospital from July 2020 to June 2022 were selected. They were divided into non infection group (n=185) and pneumonia group (n=83) according to whether they were complicated with postoperative pneumonia. The pneumonia group was divided into severe pneumonia 31 cases and common pneumonia 52 cases according to the severity of pneumonia. Serum PCT and CRP levels were measured by ELISA; The serum LDH level was detected by enzyme colorimetry, and the correlation between the serum LDH, PCT, CRP levels and the severity of the disease in patients with pneumonia was analyzed by Pearson correlation test. ROC curve was used to analyze the clinical diagnostic value of serum LDH, PCT, CRP levels in patients with severe pneumonia after craniocerebral surgery, and the prognostic value of serum LDH, PCT, CRP levels in patients with severe pneumonia after craniocerebral surgery. Results: The levels of serum LDH, PCT and CRP in patients with common pneumonia were significantly higher than those in the uninfected group on the 1st, 3rd and 7th day after operation (P<0.05); Compared with the common pneumonia group, the serum LDH, PCT and CRP levels in the severe pneumonia group were significantly higher (P<0.05). Pearson correlation test showed that serum LDH, PCT, CRP levels were positively correlated with PSI scores in patients with craniocerebral surgery complicated with pneumonia (P<0.05). The ROC curve was established based on the serum LDH, PCT and CRP levels on the first day after operation. The results showed that the areas under the curve of serum LDH, PCT and CRP were 0.840, 0.825 and 0.746 respectively. The ROC curve was established based on the serum LDH, PCT and CRP levels 7 days after operation. The results showed that the areas under the curve of serum LDH, PCT and CRP were 0.819, 0.725 and 0.684 respectively. Conclusion: LDH is highly expressed in patients with craniocerebral operation complicated with pneumonia, which is positively related to the severity of pneumonia. LDH has good value in distinguishing non severe pneumonia patients from severe pneumonia patients and predicting the 28 day mortality of severe pneumonia patients. [ABSTRACT FROM AUTHOR]

BACKGROUND: Posterior single open-door laminoplasty (LAMP) and anterior cervical corpectomy fusion (ACCF) can effectively treat cervical spondylotic myelopathy. However, the two treatments have different effects on the postoperative cervical spine sagittal balance. OBJECTIVE: To compare the effects of LAMP and ACCF on cervical sagittal balance parameters in the treatment of multilevel cervical spondylotic myelopathy. METHODS: Seventy patients with multilevel cervical spondylotic myelopathy in First Affiliated Hospital of Bengbu Medical College from August 2017 to August 2020 were enrolled in this study. There were 40 cases in ACCF group and 30 cases in LAMP group. Lateral cervical X-ray films were taken before operation and during follow-up. C2-7 Cobb angle, C2-7 sagittal vertical axis, and T1 inclination angle were compared between the two groups. This study was approved by the Ethics Committee of First Affiliated Hospital of Bengbu Medical College. RESULTS AND CONCLUSION: (1) Compared with preoperatively, there was no significant change in the T1 inclination angle between the two groups at 10 months after surgery (P > 0.05). There was no significant difference between the two groups in the T1 inclination angle at the 10-month postoperative period (P > 0.05). (2) Compared with preoperatively, the C2-7 Cobb angle of patients in the ACCF group increased at 10 months after surgery (P < 0.05), and the C2-7 Cobb angle of patients in the LAMP group decreased at 10 months after surgery (P < 0.05). The C2-7 Cobb angle of patients in the ACCF group was greater than that of the LAMP group at 10 months after surgery (P < 0.05). (3) Compared with preoperatively, C2-7 sagittal vertical axis in the ACCF group decreased at 10 months after the operation (P < 0.05), and C2-7 sagittal vertical axis increased in the LAMP group at 10 months after the operation (P < 0.05). The C2-7 sagittal vertical axis of the ACCF group was smaller than that of the LAMP group at 10 months after surgery (P < 0.05). (4) In the ACCF group, the postoperative C2-7 Cobb angle and C2-7 sagittal vertical axis changes in patients with high T1 inclination angle were not significantly different from those in patients with low T1 inclination angle (P > 0.05). In the LAMP group, the changes of C2-7 Cobb angle and C2-7 sagittal vertical axis in patients with high T1 inclination angle were greater than those in patients with low T1 inclination angle (P < 0.05). (5) The findings showed that compared with LAMP, ACCF in the treatment of multilevel cervical spondylotic myelopathy can avoid cervical kyphosis, better maintain the physiological curvature of the cervical spine and improve the sagittal balance of the cervical spine. To avoid postoperative sagittal balance decompensation of cervical vertebra, ACCF is more suitable than LAMP for the treatment of cervical spondylotic myelopathy with high T1 inclination angle.
