Objective To evaluate the prediction value on distant metastases of fib bone marrow micrometastases (BMM) of patients with non-small lung cancer ( NSCLC ). Methods From January 2003 to March 2006, 168 patients undergoing surgical treatment for NSCLC were prospectively investigated for the presence of BMM by using immnnohistochemistry. The sensitivity and specificity of the rib bone marrow micrometastases technique were also calculated. Receiver operating characteristic curve (ROC curve)was drawn according to data. Results Occult BMM were detected in 29.76 %(50/168) of patients with NSCLC. 15(29.76 %) patients developed metastases in the 50 patients with BMM and 15 (12.71%) patients developed metastases in the 118 patients without BMM. The sensitivity and the specificity of the technique was 61.54 % and 79.84 %. The false negative rate was 38.46 % and the false positive rate was 20.16 %. The positive predictive value, negative predictive value and Youden' s index were 87.5 %, 93.33 %, 74.33 % respectively. Conclusion The detection of BMM could predict the distant metastases of non-small lung cancer patients through receiver operating characteristic curve evaluation, however, the detecting sensitivity should be improved.

Objective To evaluate the prognostic value of intraoperalive detection in rib bone marrow micmmetastasis(BMMs)of patients with non-small-cell lung cancer(NSCLC)and the relationship between the micROmetast ases and clinicopathologic factors.Method From April 2004 to May 2007,146 patients undergoing surgical treatment for NSCLC were prospectively investigated for the presence of BMMs by the immunohistochemisury method.Remits 30.82%(45/146)of NSCLC patients were detected with BMMs,15(33.33%)patients developed remote metastases of the 45 patients with BMMs,14(13.86%)patients developed metastases of the 101 patients without BMMs.Patients with BMMs demonstrated an earlier metastasis and a lower survival rate compared with patients without BMMs(P＜0.05).There Was trend for ahigher frequency and the occurrence of BMMs changed with tumor stages and the histologic differentiation of the tumor.No relationship was found between BMMs and age,T grade,as well as tumor dimension.Conclusions The detection of BMMs can predict the prognosis of NSCLC patients and identifies patients withNSCLC who are at significantly increased risk for metastasis and survival,which may be useful in evalnatingpatients for adjuvant treatment

Objective To compare the effect of postoperative intercostal nerves cryoanalgesia and patient controlled epidural analgesia (PCEA) in patients undergoing thoracic surgery. Methods From April 2006 to May 2008,89 patients undergoing thoracic surgery were randomly divided into intercostal nerves cryoanalgesia group (group A,47 cases) and PCEA group (group B,42 cases). The scores of pain, use of pain medication and time of out-of-bed activity after the operation were used to evaluate the effect of pain between two groups. Results The scores of pain in group A and group B were (1.49 ± 0.80) and (2.43 ± 1.21) scores respectively. There were significant differences in the scores of pain. The use of pain medication [(1.28 ± 0.62) times vs (2.02 ± 1.05) times]and time of out-of-bed activity after the operation [(43.15 ± 12.22) h vs (64.10 ± 14.25) hi were significant difference between the two groups(P< 0.05). Conclusions For reducing the post- thoracotomy pain,intercostal nerves cryoanalgesia is superior to PCEA. Intercostal nerves cryoanalgesia can provide satisfactory analgesia after thoracic surgery.

Nutritional support therapy includes three main components:nutritional screening,nutritional assessment,and nutritional intervention.It is important to emphasize that nutritional screening and nutritional assessment are two different concepts and definitions,which are often confusing for many physicians,nurses,and dietitians.In this review,we present an overview on the main concepts about nutritional screening and nutritional assessment,highlight their features and complementarity,and discuss the future perspectives in the clinical practice.

The bovine jugular veins were divided into two groups and treated with 4% EX-313 and 0.5% glutaraldehyde respectively, and then they were examined with naked-eye, microscope and scanning electron microscope. Biomechnics test and dorsal implantation in rats were performed. The aquired data were processed and subjected to t-test. The EX-313 fixed material was more pliable than the glutaraldehyde treated material, and the former had higher anticalcification than the latter. In conclusion, the hydrophilia crosslinking agent EX-313 is superior to glutaraldehyde in treating biomaterials, and the bovine jugular vein tanned with EX-313 should be a promising material for repairing in cardiovascular surgery.

The three steps of nutritional care in Europe, the United States and China were basically same as [Nutritional screening-assessment-intervention]. This review article discussed the second step of GLIM for diagnosis of malnutrition, when the diagnosis of malnutrition being needed. No normal range in healthy volunteer and no cut-off point based on clinical studies for FFMI in China now.

In the 42 nd and 44 th workshops of CSPEN-nutritional risk-undernutrition-support-outcome-cost effectiveness ratio (NUSOC) multi-center database collaboration group, Jens Kondrup and Henrik Rasmussen described again the application of NRS 2002, the evidence-based basis of NRS 2002 development and the methodology for prospective validation of clinical effectiveness. There is no gold standard for validation. They both considered that malnutrition could be identified as a score of 3 or more for impaired nutritional status in NRS 2002. Although NRS 2002 is simple and easy to be applied, it is not comprehensive enough for malnutrition diagnosis. ASPEN and ESPEN on-line published the Global Leadership (nutritional) Initiative on Malnutrition(GLIM)diagnosis criteria in September 2018. With the gradual implementation of medicare payment based on diagnosis related groups(DRG)in China, the nutritional risk and the malnutrition diagnosis with Chinese version of ICD-10 (2016) code should be recorded in the first page of the medical records. In this terminology interpretations, the terms of nutritional risk screening(NRS 2002.01.016)and malnutrition diagnosis (GLIM-phenotypic criteria 01.028, etiologic criteria 01.029) published in Parenteral and Enteral Nutrition Terminology 2019 are discussed based on the reports given by Kondrup and Rasmussen in Beijing and Zhengzhou.

The ultimate goal of the development of parenteral and enteral nutrition is to achieve T3 transfer of translational medicine in this field. This study is an international cooperative, multicenter and observational clinical study conducted by CSPEN-NUSOC cooperative group for 15 years which is aimed to observe the effect of standardized nutritional support on clinical outcome and cost/effect and verify the clinical value parenteral and enteral nutrition through investigating the prevalence of nutritional risk and malnutrition and the application of nutritional support in adult in-patients.

Stroke is one of the most common cerebrovascular diseases， including hemorrhagic stroke and ischemic stroke. From a modern medical perspective， stroke is caused by cerebrovascular damage or embolism leading to impaired blood circulation. From the traditional Chinese medicine （TCM） perspective， the pathogenesis of this disease is mainly due to the disorder of Qi and blood， which ascend to the brain， causing either blood extravasation or blockage of brain collaterals. Stasis is a pathological factor that runs throughout the entire course of stroke， and the method of promoting blood circulation and resolving stasis has been a core treatment for stroke for a long time. Hirudo， as a traditional insect drug， has shown good effects in promoting blood circulation and resolving stasis. Modern pharmacological research has confirmed that Hirudo contains anticoagulant components， which provide significant advantages in dissolving thrombi in ischemic stroke and facilitating hematoma absorption in hemorrhagic stroke. Hirudo and its related preparations have been proven to exert an anti-stroke effect through anticoagulation， anti-thrombosis， and protection of vascular endothelium. As a result， they have been widely used in the treatment of stroke. This article explored the theoretical basis and research status of using Hirudo for treating stroke based on its main active components and hemostatic properties and summarized the current research status of commonly used Hirudo-based formulations and preparations， aiming to provide references for the involvement of Hirudo in stroke treatment.

It is well known that parenteral and enteral nutrition support is helpful to improve clinical outcomes in patients with malnutrition or nutritional risk, and surgical nutrition has been used in China for 40 years. However, there is still insufficient awareness of malnutrition among clinical workers. There were different opinions from many experts after the publications of the European Society for Parenteral and Enteral Nutrition (ESPEN) consensus of malnutrition assessment 2015 and ESPEN guidelines on definitions and terminology of clinical nutrition 2017. Global Leadership Initiative on Malnutrition (GLIM) criteria for the diagnosis of malnutrition has also been published in 2018. Though it is lack of clinical validation, it is a big step forward. In order to achieve better prevention and treatment of malnutrition in clinical work, this present paper analyzes and compares the core contents of malnutrition assessment (diagnosis) in recent years, proposes current practical strategy for Chinese clinical workers, emphasizes that GLIM criteria cannot replace the three steps named "screening-assessment-intervention" .
