With the low-dose spiral computed tomography (LDCT) widely applied in screening for early-stage lung cancers recently, positive rates of Ground-Glass Opacity (GGO) are gradually increased. Many professional researchers believe GGO has a close relationship with the early-stage lung adenocarcinoma, consequently, qualitative diagnosis and early treatment of GGO plays a signiifcant role in improving the diagnostic and survival rates of patients with early-stage lung cancer. Since relative imaging diagnosis, location methods and surgical approaches of GGO have been reported a lot by domestic and overseas researchers, our reviews would mainly focus on the diverse research progress of molecular biology of GGO in the past several years.

Objective:To explore the establishment of an animal model of abdominal aortic aneurysm(AAA),and elaborate the role of iNOS inhibitor in the smooth muscle apoptosis of abdominal aortio aneurysm in rats,to find a new theoretical basis for the clinical treatment of small drugs AAA.Methods:SD rats underwent intra-aortic elastase (25U/mL) perfusion to induce AAAs,the positive control group (30) and experiment group (30) use elastase perfusion while the negative control group(30) gives the saline perfusion.After operation the positive and negative control groups were treated with intraperitoneal injections of saline,experimental group injects the iNOS inhibitor Aminoguanidi hydrochloride;Postoperative second,7,and 14 days,The NO content in the serum and specimen of abdominal aortic aneurysm was detected by iNOS Immuno histochemistry and Terminal Transferase-mediated dUTP Nick End-Labeling (TUNEL) to evaluate distribution of smooth muscle apoptosis in abdominal aortic aneurysm.Results:Underwent intra-aortic elastase perfusion to induce AAAs have a high-success-rate.Rate of AAA formation in positive control group 10％,60％,80％,respectively.The treatment group was 0％,10％,20％,and the negative control group was not formed.The treatment group and the negative control group were lower than the positive control group,there were significant differences.In the positive control group,NO content increased gradually from second days,7 days to reach the peak and maintained at a higher level,the treatment group serum NO content was lower than the other two groups,there was significant difference (P＜0.05),iNOS was strong expression in the positive control group,in the other two groups of mild expression.TUNEL results showed that a lot of apoptotic cells in the positive control group,after 7 days showed a significant increase trend,to observe the end (2 weeks) gradually increased.,The positive control group was higher than the negative control group and the negative control group,there was significant difference(P＜0.05).Conclusion:iNOS inhibitors significantly decreased the content of NO in serum,reduced the apoptosis of smooth muscle cells,and inhibited the formation of abdominal aortic aneurysm.To provide theoretical basis for clinical application of iNOS inhibitors in the treatment and control of AAA.

Apoptosis is an organized suicide program which is evolutionally conserved from yeast to mammals. Research on yeast apoptosis has made rapid progress, though it remained unrecognized until recent years. Initial observations show that yeast can be induced to undergo apoptosis and a number of conserved pro- and antiapoptotic proteins have been identified in Saccharomyces cerevisiae. Yeast has been validated as a model organism to investigate mechanisms of apoptosis. Recently, yeast has also been used as a model to study apoptosis-related disease, such as Huntington's disease and Parkinson′s disease. The feasibility, the advantages and the perspectives of yeast model for apoptosis research are reviewed.

As the actual clinical reflecting of transform Chinese medicine special curative effect, Chinese medicine preparation not only satisfies the need of hospital clinic, scientific research and teaching, but also plays an important role in deepening medical and health system reform, improving people's health level and contributing to the economic growth. However, some problems about administration and approval (tending to western medicine), contraction of the scale, lack of synchronization for clinic and scientific research, and the imbalance of regional development make Chinese medicine preparation move forwards slowly in contradiction. It has not only reduced the effectiveness of the Chinese medicine preparation in hospital clinic, but also brought bad effect on modernized development of Chinese medicine preparation. Research shows that main influencing factors of status quo of Chinese medicine preparation in medical institution include imperfect laws and regulations, high cost than income, and shortage of talents in preparation research. The analysis indicated that the necessary measures to break the contradiction, improve clinical effect of Chinese medicine, and promote the modernization development of Chinese drugs preparation were as follows: government and related departments should strengthen the supporting force in policy by adjusting the examination and approval policy, speeding up dispensing use, reforming pricing system, including into medicare reimbursement, integrating advantage resources and so on; medical institution should actively carry out research and development of traditional Chinese Medicine through drawing the traditional and modern essence, reserving professional talents, and developing characteristic preparation; companies cooperate with hospitals for complementary advantages, which can rapidly transform Chinese medicine preparation into clinical practice.

Objective To explore the clinical significance of osteopontin (OPN) in systemic lupus erythematosus (SLE) and its pathogenic role in SLE by studying the correlation between OPN and clinical manifestations,laboratory parameters and disease activity.Methods The enzyme-linked immunosorbent assay(ELISA)was used to measure the level of OPN in serum of 68 SLE patients and 20 healthy controls.the clin-ical data and laboratory parameters were recorded.Results The positive rate of OPN was 79.41%in 68 SLEpatients and could not be detected in healthy controls.Compared with healthy controls.the positive rate and level of OPN in SLE patients was significantly higher(P＜0.01).There was no significant difference in age.gender and disease duration between OPN positive and negative lupus patients(P＞0.05).The Drevalence of fever,hair loss,WBC decrease,liver damage,serum C4 decrease,proteinuria and anti-dsDNA antibody in OPN positive SLE were significantly higher than those of OPN negative SLE(P＜0.05).The positive rate of serum OPN in SLE patients was significantly higher than that of anti-dsDNA antibody and anti-Sm antibody (P＜0.01).The level of plasma OPN was associated with systemic lupus erythematosus disease activity index (SLEDAI)(r=0.292,P＜0.05).The positive rate and level of OPN in active SLE patients was significantly higher than that of inactive SLE patients(P＜O.05).Conclusion The level of plasma OPN has a close rela-tionship with the activity of SLE.It may serve as an active disease marker of SLE.

Objective To analyze the clinical characteristics of systemic lupus erythematosus (SLE) patients with septic arthritis.Methods Twelve SLE patients with septic arthritis admitted to Peking Union Medical College Hospital from January 1990 to December 2012 were retrospectively analyzed.Results The median duration from onset of SLE to septic arthritis was 8.5 months (ranged from 1 to 120 months).All patients had received higher doses of steroid therapy (equal to prednisolone 1 mg ·kg-1 ·d-1) and immunosuppressant,and 5 of them had received methylprednisolone pulse therapy.The infectious manifestations included joint pain (all cases),swelling (5 cases),reduced joint function (8 cases) and fever (10 cases).All patients were oligo-arthritis.The hip and knee joints were most commonly involved.Three patients were infected by Salmonella,4 patients were infected by S.aureus,and 3 patients were infected by tuber culosis.Conclusion When SLE patients with long term steroid and immunosuppressant therapy developedacute joint pain and swelling,septic arthritis should be considered.Synovial fluid Gram stain,culture,blood culture and arthroscopy should be performed promptly.Appropriate antibiotics should be administered,and early treatment can improve the outcomes.

Objective To evaluate endoscopic ultrasonography (EUS) in preoperative staging of gastric carcinoma,and to study the molecular biologic basis of its ultrasonic manifestation.Methods Sev-enty-four patients with gastric carcinoma were referred to EUS and staged preoperatively.The staging esults of EUS were compared with the histopathological staging and the expression of PTEN.Results The verall accuracy rate of EUS for determination of T staging was 82.4%(61/74),for T1,T2,T3 and T4 were 100.0%,72.7％,85.O％ and 78.9％,respectively.For N staging,EUS had the overall accuracy rate of 74.3%(55/74),with sensitivity and specificity of 80.8％ and 59.1％,respectively.The preoperative EUS for T and N staging of gastric carcinoma was of inverse correlation with the expression of PTEN.Conclusions EUS is an accurate staging modality in determining carcinoma invasive depth and lymph node involved,with a few exceptions of overstaging and understaging.However,EUS criteria to differentiate benign from malignant nodes still need to be further defined by future studies.The preoperative EUS for T and N staging could well display the molecular pathologic basis of gastric carcinoma.
