Based on the theory of "shaoyang（少阳） resembling the pivot" and collateral diseases， this article proposes that pulmonary fibrosis （PF） can be divided into three stages including wind bi （痹）， constraint bi， and atrophy bi. The core pathogenesis of PF is the obstruction of the pivot and pulmonary collateral obstruction. In terms of treatment， the basic principles are to harmonize and regulate the pivot， and to promote the circulation of the lung collaterals. Depending on the different characteristics of the "essence-attribute-function"， treatment methods such as harmonizing and regulating the pivot， resolving phlegm and removing stasis， supplementing deficiency and harmonizing collaterals are suggested. This approach ensures the regulation of the pivot， smooth circulation of qi and blood， unblocking of the lung collaterals and nourishing the lung body， achieving the goals of balancing the ascending and descending of qi， removing phlegm and stasis， and relieving cough and wheezing.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

This paper summarized the characteristics of constitution， disease， and syndrome of five different phenotypes of bronchial asthma including allergic asthma， cough variant asthma， chest tightness variant asthma， psychological stress asthma， and hormone-dependent asthma， and systematically expounds the application of three-dimensional diagnosis and treatment pattern， that is differentiation of constitution， disease and syndromes in the five phenotypes of bronchial asthma. It is considered that the allergic constitution is the main one of bronchial asthma， which is usually combined with the constitutions of qi-deficiency， yin-deficiency， yang-deficiency， qi-stagnation and others. In the treatment of bronchial asthma， constitution， disease and syndromes should all be taken into account but applied flexibly according to the order of the urgency and priority. The three-dimensional diagnosis and treatment pattern can reflect the essential characteristics and clinical panorama of bronchial asthma more comprehensively and objectively and provide effective intervention measures and management programs for the prevention and treatment by traditional Chinese medicine.

OBJECTIVETo analyze the efficacy and toxicity of concurrent chemoradiotherapy (CCRT) for patients with locally advanced non-small-cell lung cancer (LA-NSCLC).

METHODSClinical data of 251 patients with stage III (76 IIIA and 175 IIIB) NSCLC who received CCRT as initial treatment between Jan 2001 and Dec 2010 in our hospital were reviewed. A median total radiotherapy dose of 60 Gy (range, 50-74 Gy) were delivered. 174 patients were treated with IMRT, 51 with 3D-CRT and 26 with 2D-radiotherapy. EP chemotherapy regimen was administered in 112 patients, PC regimen in 99 patients, topotecan regimen in 18 patients and other regimens in the remaining 22 patients. The efficacy and toxicity of CCRT were retrospectively analyzed.

RESULTS244 patients were assessable for response, including 6 (2.5%) patients with CR, 183 (75.0%) with PR, 42 (17.2%) with SD and 13 (5.3%) with PD. At a median follow-up period of 20 months, the 1-, 3-, 5- year OS were 69.2%, 31.2%, 23.2%, respectively, and the median OS was 21 months. The 1-, 3-, 5- year PFS were 40.9%, 22.1%, 17.7%, respectively, and the median PFS was 10 months. Patients with stage IIIA NSCLC achieved better 5-year OS than that with IIIB NSCLC (29.2% vs. 20.7%, χ2=2.254, P=0.133). Failure pattern was assessable in 244 patients, including 61 (25.0%) locoregional progression alone, 55 (22.5%) distant metastasis alone and 77 (31.6%) with both. The rates of grade≥3 radiation pneumonitis, esophagitis and hematologic toxicity were 4.4%, 11.2% and 26.4%, respectively.

CONCLUSIONSCCRT provide stage III NSCLC patients favorable outcome with acceptable toxicity. CCRT is standard therapeutic approach for patients with unresectable locally advanced NSCLC.

OBJECTIVETo investigate the differences between clinicopathological features and prognosis of alpha-fetoprotein (AFP) negative (AFP < 20 ng/ml) and positive (AFP ≥ 20 ng/ml) hepatocellular carcinoma (HCC) patients.

METHODSClinicopathological data of 142 AFP-negative and 109 AFP-positive HCC patients who underwent RO radical hepatectomy in the Cancer Hospital of Chinese Academy of Medical Sciences between January 2006 and December 2011 were retrospectively reviewed and analyzed in this study.

RESULTSCompared with the AFP-negative patients, a higher female to male sex ratio, the later Barcelona Clinic Liver Cancer ( BCLC) stage, more liver capsule invasion and poorer Edmondson-Steiner grade were in the AFP-positive cases (P < 0.05 for all). Furthermore, the 1-, 3-, and 5- year overall survival rates were 94.4%, 82.4% and 61.0% in the AFP-negative group and 87.2%, 61.1% and 40.2%, respectively, in the AFP-positive group (P < 0.001). The multivariate analysis with Cox's proportional hazards model showed that AFP status, tumor size and Edmondson-Steiner grade are independent risk factors for survival of all the patients (P < 0.05) , and large tumor and Edmondson-Steiner grades III/IV are independent risk factors for worse survival in AFP-negative patients (P < 0.05). However, large tumor diameter was proved to be an independent risk factor leading to poor prognosis of AFP-positive cases (P < 0.05).

CONCLUSIONHigh levels of AFP indicate that the tumors are more malignant and with unfavorable prognosis.

Objective To explore the incidence and related predictive factors for acute symptomatic esophagitis in patients with locally advanced non?small cell lung cancer ( NSCLC ) treated with intensity?modulated radiation therapy ( IMRT) . Methods Data were collected retrospectively from 256 patients with inoperable or unresectable stage Ⅲ NSCLC treated in our hospital between January 2007 and December 2011. The radiotherapy target volume included primary lung cancer and lymphatic drainage area involved,with a median dose of 60 Gy in 30 fractions (50-70 Gy).Of all the patients,109 patients (42.6%) received concurrent chemotherapy. Grade ≥2 acute esophagitis ( AE ) ( symptomatic esophagitis ) which occurred during radiotherapy and within 3 months after completion of radiotherapy served as the outcome event. National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0( NCI?CTCAE3.0) was used to evaluate the grade of AE. The logistic regression model was used to analyze the predictive factors. Results A total of 174 patients ( 68%) had treatment?related grade ≥2 AE;154 patients ( 60. 2%) had grade 2 AE and 20 patients (7.8%) had grade 3 AE.The median dose when grade≥2 AE occurred was 30 Gy (11?68 Gy).For grade≥2 AE,multivariate analysis showed that esophageal V5?V60,mean dose,and age were independent predictive factors (P=0.021,0,0.010).For grade ≥3 AE,multivariate analysis showed that esophageal V50?V60 ,concurrent chemotherapy,and body mass index ( BMI) were independent predictive factors ( P= 0.010,0.003,0.019 ) . Old age and higher BMI were the protective factors for grade≥2 and ≥3 AE, respectively. Conclusions For patients with locally advanced NSCLC treated with IMRT, esophageal V50—V60 and concurrent chemotherapy are predictive factors for grade ≥3 AE,and esophageal V50 has a high predictive value for both grade ≥2 and ≥3 AE.
