Article Synopsis
- - Stand-level biomass carbon models are vital for assessing forest carbon storage in China, serving as a foundation for both national and international evaluations.
- - This research utilized data from 52,700 permanent plots to create accurate biomass and carbon storage models for 20 forest types, revealing a significant recovery in forest carbon storage from 4.90 Pg in the late 1970s to 8.69 Pg by the 9th National Forest Inventory.
- - The study highlights the importance of larger sample sizes in modeling, as comparisons with existing models showed biases, marking a significant advancement in monitoring China's forest carbon dynamics.

Article Synopsis
- A study was conducted to apply lidar technology for estimating standing stocks in conifer forests of Northeast China, using airborne lidar point cloud data and information from 800 ground plots.
- Two modeling approaches, stepwise regression and partial least squares, were employed, with partial least squares showing superior accuracy (RRMSE=2.6%-4.2%).
- The models ranked the accuracy of the forests as follows: best for Korean pine (R^2=0.79), followed by larch (R^2=0.76), spruce-fir (R^2=0.81), and var. mongolica forest (R^2=0.50), highlighting the significance of height variables in modeling.
[Surgical treatment for bronchioloalveolar carcinoma with ipsilateral intrapulmonary metastatic nodules].
Zhonghua Zhong Liu Za Zhi
August 2009
Objective: The staging and treatment of bronchioloalveolar carcinoma (BAC) with pulmonary metastasis are still controversial. This study aimed at evaluating the current staging of BAC with ipsilateral intrapulmonary metastatic nodules and the therapeutic effectiveness of surgical resection.
Methods: The clinicopathological data of 729 completely and surgically resected patients with non-small cell lung cancer (NSCLC) from December 1999 to December 2006 were retrospectively reviewed.
[Surgical treatment of ipsilateral multi-focal non-small cell lung cancer].
Zhonghua Wai Ke Za Zhi
July 2009
Objectives: The staging and treatment of multi-focal non-small cell lung cancer (NSCLC) are controversial. This study evaluated the effectiveness of surgical treatment for the ipsilateral multi-focal NSCLC.
Methods: Sixty-eight patients with multi-focal NSCLC underwent complete resection from December 1999 to December 2006.
Background: In order to reach a clear understanding of minimally invasive approaches in cardiac operations, the authors review clinical experience in using three such approaches: inferior partial median sternotomy, right anterolateral minor thoracotomy, and the right parasternal approach.
Material/methods: Sternotomy and the three different minimally invasive approaches were applied in and 2431 and 323 patients respectively. The approaches were selected according to the circumstances of the individual case.
[Evaluation of left parasternal approach for cardiac surgery].
Di Yi Jun Yi Da Xue Xue Bao
March 2002
Objective: To provide a systemic evaluation of left parasternal approach (LPSA) for its clinical application.
Methods: LPSA was performed in 6 randomly-chosen formalin-preserved adult cadavers and the excisions were evaluated in external light of the external appearance, extent of traumatic injury and exposure of the structures in the thoracic cavity.
Results: LPSA left only short and less obvious skin incisions, thus causing minimal exterior appearance impairment.
