1.Bronchial asthma with rhinitis,sinusitis and nasal polyps.
Chinese Journal of Practical Internal Medicine 2001;0(04):-
Rhinitis,sinusitis,nasal polyps and bronchial asthma are common respiratory diseases,and they have some similarities in etiology,pathogenesis,histopathology and pathophysiology.Many patients suffer from these diseases in succession,or at the same time.Many domestic and international clinical and fundamental studies have aroused widespread concern about the relevance of these diseases,with the correlations between nasal polyps-sinusitis and asthma that attribute to much attention.However,the relevance of extent on the study of these diseases,as well as diagnosis,treatment,and concept is not very clear yet.The main target of this article is to discuss the above issues and remind our clinicians to pay more attention to understand the comprehensive relationships of rhinitis,sinusitis,nasal polyps and bronchial asthma,and provide references for the strategy of rational and effective treatment options.

Tumor 2012;32(3):149-158
Objective: To investigate the effects of gene silencing and overexpression of RACK 1 (receptor for activated C kinase 1) on the proliferation of large-cell lung cancer H460 cells and lung adenocarcinoma A549 cells, and to explore the possible mechanism. Methods: The RACK1 siRNA (small interfering RNA) targeting RACK 1 gene and recombinant vector pCMV-sport6-RACK1 were transfected into both of H460 cells and A549 cells, respectively. MTT method and colony formation assay were used to detect the effect of RACK 1 gene expression on the proliferation of lung cancer cells. Flow cytometry was used to examine the change of cell cycle. The association and interaction of RACK 1 gene expression with the proliferation of lung cancer cells were analyzed by yeast two-hybrid system, co-immunoprecipitation, laser scanning confocal microscopy and co-immunoprecipitation of phosphoproteins. Results: The expression levels of RACK1 protein in the H460 cells and A549 cells were both decreased after transfection with RACK1 siRNA, and the abilities of proliferation and colony-formation were also weakened. The proportion of lung cancer cells arrested at phase S was significantly declined (P <0.01). Meanwhile, the expression level of RACK1 protein was increased after transfection with pCMV-sport6-RACK1, and the abilities of proliferation and colony-formation of lung cancer cells were both strengthened with a prolonged doubling time. The proportion of lung cancer cells arrested at phase S was significantly increased (P <0.01). The results of yeast two-hybrid system and co-immunoprecipitation revealed that RACK1 could directly interact with MCM7 (minichromosome maintenance protein 7). The phosphorylation of MCM7 protein was strengthened through binding to RACK1 which translocated into the cell nucleus. Conclusion: RACK1 promotes the proliferation of lung cancer cells through activating the phosphorylation of MCM7 binding to RACK1. Copyright© 2012 by TUMOR.
5. Effects of autophagy on quercetin-induced death of SMMC-7721 cell
Chinese Pharmaceutical Journal 2012;47(13):1052-1056
OBJECTIVE: A im To investigate the role of qercetin(Que) -induced autophagy in the death of hepatocellular carcinoma cell line SMMC-7721 cells. METHODS: After treatment with different concentration of Que, the growth inhibition of the SMMC-7721 cells were assessed by MTT colorimetric assay. The fluorescent staining was applied to identify the autophagy after Que treatment. Lactate dehydrogenase (LDH) leakage and Western blot analysis were used to study the autophagic mechanisms involved in death of SMMC-7721 cells. RESULTS: The proliferation of SMMC-7721 cells were significantly inhibited in a dose and time-dependent manner after Que treatment. Autophagy was also induced in MCF-7 cells as detected by MDC staining and Fluorescent staining in the early phase. The autophagy specific inhibitor 3-MA or chloroquine potentiated Que's cytotoxicitiy in SMMC-7721 cells when administered 1h before Que; The expression of cathepsin B increased after Que treatment. CONCLUSION: Que can significantly inhibit the growth of the SMMC-7721 cells by inducing the autophagy, which is a protection mechanism that can reduce the cytotoxicity induced by Que in SMMC-7721 cells. The activation of Cathepsin B is considerable in autophagy process.

Objective To investigate the clinical effects of retroperitoneal laparoscopic surgery in the management of diseases of adrenal glands, kidneys and ureters. Methods By using a closed puncture into retroperitoneal space to establish a surgical access ,87 patients with diseases of adrenal glands, renal cysts, ureteral calculi and ureteral deformities were operated on by means of retroperitoneal laparoscopic surgery. Results The surgery was successfully accomplished in 83 patients with an excellent therapeutic effect, whereas a conversion to open surgery was required in 4 patients. There were no blood transfusions or serious complications in the study. Conclusions Retroperitoneal laparoscopic operations of adrenalectomy, cyst unroofing, ureterolithotomy, ureterolysis and ureteroplasty has the advantages of minimal invasion, less blood loss and fewer complications, being an effective and practical procedure .

The sample introduction system of a cool vapor atomic fluorescence spectrometer made domestically was modified for taking the mercury vapor which was pre-concentrated in a capture mercury gold cartridge as gold amalgam generated on-line by pyrolyzing atmospheric particulate collected from an air conditioner. The temperatures that applied) to sample pyrolyzer to generate elemental mercury and capture mercury gold cartridge to release mercury from amalgam were 700-750 ℃ and 550 ℃, respectively. The carrier Ar flow rate was 120 mL/min. The method detection limit was 1 pg, mercury content showed a linear relationship in 0-1.5 ng), and RSD was 2.2%. The method was validated by determining mercury in the national soil standards) GBW07410. The method was Applied to determine the mercury content in the atmospheric particulate from a hospital air conditioner.

Radiotherapy (RT) is the primary treatment for nasopharyngeal carcinoma (NPC). In order to achieve tumor control, nearby normal brain tissues, especially the temporal lobes, often receive unnecessary radiation. Patients with NPC treated by RT may occur cognitive impairments, which significantly compromises the quality of life. The symptoms of cognitive dysfunction induced by RT in NPC patients can exhibit at the early or later stage after RT, which may be related to temporal lobe injury or brain damage induced by radiation. However, the relationship between the cognitive declines induced by RT and the radiation dose or volume of the temporal lobe (or the dosimetry to treat NPC) has not yet been definitively established, and few reports have focused on cognitive impairment following intensity modulated RT. Therefore, this paper will review the progress in radiation-induced cognitive decline of NPC patients in order to provide the basis for preventing side effects of RT and improving the quality of life after RT.

Journal of Clinical Neurology 1993;0(03):-
Objective To explore the clinical effect of mobilization and harvesting by autologous peripheral blood stem cell transplantation (APBSCT) on treating myasthenia gravis (MG).Methods One patient with MG was enrolled in the study. Autologous peripheral blood stem cells(APBSCs) were mobilized with cyclophosphamide(CTX) and granulocyte colony-stimulating factor(G-CSF). PBSCs harvesting was performed by continuous flow leukapheresis using a CS-3000 plus blood separator.CD +_ 34 cells were analyzed by flow cytometer and granulocyte-macrophage progenitors (GM-CFU) was detected by semisolid methlcelluose after mobilization. The clinical effect was evaluated by a relative score system.Results The numbers of mononuclear cells (MNC),GM-CFU and CD +_ 34 cells were 8.08?10 8/kg,7?10 5/kg or 81/10 5/MNC and 1.09?10 6/kg after mobilization in graft respectively. The clinic relative score of the patient was 7/8.Conclusion CTX and G-CSF can mobilize effectively and provide enough peripheral blood stem cells for transplantation in treating MG.
