Objective To investigate signal transduction and cytokine gene expression pattern in peripheral blood mononuclear cell (PBMC) between primary Sjogren syndrome patients and healthy controls. Methods The PBMC of 3 patients with Sjogren syndrome and 3 healthy volunteers with consistent age were collected. The total RNA extracted from the PBMC was carried the reverse transcription and in vitro transcription (IVT), then labeled with Cy5/Cy3 and hybridized on the gene chips. After scanning and data extraction with LuxScan 3.0, differentially expressed genes were analyzed with SAM method. The online tools of molecule analysis system (MAS) was used for biological knowledge mining. The difference of signal transduction and cytokine gene expression of each patient and control were compared. Results Statistical difference was calculated between the patient and control group in the following four pathway: the chemokine-cytokine receptor interaction pathway[(FASLG(Fas ligand), CCL5, CCR3, IL-4R, CXCL10 (CXC chemokine ligand 10), TNFRSF19L (tumor necrosis factor supeffamily 19 ligand), CX3CR1 (CX3C chemokine receptor 1)], adhension molecule pathway [interleukin adhesion molecules-1 (ICAM-1)], Jak-STAT signal pathway [STAT4 (signal transducer and activation of transcription 4), CISH (chromogenic in situ hybridization), IL-4R], Toll-like receptor signal pathway(CCL5, CXCL10). Among these, 4 genes were up-regulated and 6 genes were down-regulated. Conclusion Understanding of differently expressed genes should help us disclose the potential molecular mechanism underlying the development process of pathogenesis of primary Sjogren syndrome.

Aim To investigate the effects of starfish saponins(Sfs) on insulin signaling pathway in orotic acid-induced NAFLD rats.Methods 1% orotic acid was used to establish NAFLD model in male Wistar rats for six weeks.The NAFLD rats were randomly divided into two groups(eight rats in each group) and then fed with the corresponding diets: Model group(1% orotic acid)and Sfs group(1% orotic acid containing 0.04% starfish saponins).After starfish saponins feeding for 8 weeks, hepatic lipids content, liver function indices and relevant protein expression in muscle insulin signaling pathway were measured.Results Compared with model group, starfish saponins reduced hepatic lipids content and improved liver functions.In addition, it effectively ameliorated insulin resistance by improving insulin signaling pathway and improved glucose uptake in muscle.Conclusion The amelioration effect of starfish saponins on impaired insulin signaling pathway in muscle is observed in orotic acid-induced NAFLD rats.

OBJECTIVE: To study the correlation between the bacterial biofilm formation and bacterial culture in chronic otitis media. METHOD: As a prospective reserch, we used scanning electron microscopy to examinate patients samples which collected from 32 cases of patients with chronic suppurative otitis media and middle ear cholesteatoma in the operations, and performed the middle ear secretions bacterial culture. According to the different types of chronic otitis media group, we analysised the relationship between chronic otitis media bacterial biofilm formation and the bacterial culture results. RESULT: Chronic suppurative otitis media (activity) and middle ear cholesteatoma bacterial biofilm formation rate were 87.5%, 81.3%, chi-square (P > 0.05). Compared bacterial biofilm results with the results of bacterial cultured in chronic otitis media, sensitivity was 70.37%, specificity was 60.00%, the misdiagnosis rate was 40.00%, the missed diagnosis was 29.63%, positive predictive value was 90. 46%, negative predictive value was 27.27%, accuracy was 68.75%. Youden index was 30. 37%, and Pearson correlation coefficient was 0.232 (P > 0.05). CONCLUSION Chronic suppurative otitis media (activity) and middle ear cholesteatoma bacteria had a higher biofilm formation rate. The routine bacterial culture results can't reflecte bacterial biofilm formation in chronic otitis media. We need to explore more reliable experimental methods to accurately reveal the infection status of chronic otitis media.

Objective To analyze the efficacy and cosmetic results of intensity modulate radiation therapy (IMRT) for breast cancer after breast-conserving surgery.Methods From 2003 to 2006, 117 patients with breast cancer, after breast-conserving surgery followed by 4 - 6 cycles of chemotherapy,received intensity modulated radiotherapy (IMRT) or three-dimensional conformal radiotherapy (3DCRT).The radiation dose was 50 Gy in 25 fractions to the whole breast and 10 Gy boost to the tumor bed.Patients with positive hormone receptors then received endocrine treatment.Results The follow-up rate was 94.0% until September 2009.114 and 91 patients were followed up to 3 and 5 years, respectively.The 3-and 5-year overall survival rates were 99.1% and 96%.The 5-year disease free survival and local recurrence rates were 88% and 3.6%.Cosmetic results were satisfied.Severe radiation toxicities, such as radiation pneumonitis, pulmonary fibrosis and heart injury were not found.Conclusions Patients treated with IMRT after breast-conserving surgery have a satisfied prognosis as well as cosmetic results.

Neonatal encephalopathy (NE) is one of the major causes of neonatal death and severe disability in childhood.The etiology of NE is complex, which can occur in prenatal or delivery, and some neonates may even have high risk factors in both prenatal and delivery.Prenatal maternal diseases, hereditary diseases and genetic predisposition, hypoxic-ischemic encephalopathy, infections, placental abnormalities, thrombosis, abnormal blood coagulation, and metabolic diseases can all directly cause NE.Some patients of NE have comorbidities such as neuromuscular diseases, congenital heart disease, severe anemia, and severe pulmonary diseases, which lead to the disturbance of extrauterine adjustment during delivery, and the occurrence of hypoxic-ischemia leading to NE.NE is a heterogeneous disease, and the selection of appropriate assessment based on the medical history and examination, identification of the etiology of NE and treatment for the etiology can improve the prognosis.

Objective To analyze the effects of Hual qi huang granules on children with mycoplasma pneumoniae pneumonia.Methods A randomized,multicenter parallel controlled clinical trial was carried out.A total of 3 000 cases of hospitalized children with mycoplasma pneumoniae pneumonia were selected.All of them were given treatment for mycoplasma pneumoniae pneumonia with macrolide antibiotics and symptomatic treatment.They were randomly divided into 2 groups:research group and control group.The children of research group were give oral Huai qi huang granules for three months.According to the classification of pneumonia,these two groups were divided into:lobar pneumonia research group,lobar pneumonia control group,lobular pneumonia research group,lobular pneumonia control group.The hospitalization duration of fever,length of hospital stay,the absorption area of lung inflammation and pneumonia severity sores were observed.The frequency of upper respiratory infections,bronchitis,pneumonia were observed in 3 months after discharge.Results 2 378 cases were investigated.The hospitalization duration of fever,length of hospital stay of research group were significantly shorter than that of in control group (P ＜ 0.001).The children with lobar pneumonia,2 weeks after treatment,the absorption of consolidation of the lobar pneumonia research group is significantly better than lobar pneumonia control group (P ＜0.001).After two weeks treatment,the pneumonia scores of lobar pneumonia research group is lower than lobar pneumonia control group (P ＜ 0.05).Followup of 3 months after hospital discharge,frequency of upper respiratory infection and bronchitis of research group,were significantly lower than that of control.In addition,appetite increased significantly in research group than control (P ＜ 0.001).There are 21 cases with drug associated adverse reactions (mild diarrhea),including 12 cases of research group,9 cases of control group,and there was no statistical significance (P ＞0.05).Conclusion Standard treatment combined with oral Huai qi huang granules in the treatment of mycoplasma pneumoniae pneumonia,can significantly shorten hospitalization duration of fever,length of hospital stay and reduce the severity score of pneumonia.Three months oral Huai qi huang granules can significant reduce the frequency of respiratory infections and bronchitis,also can increase patients appetite,and be safe.

We report a complete genomic sequence of rare isolates (minor genotype) of the SARS-CoV from SARS patients in Guangdong, China, where the first few cases emerged. The most striking discovery from the isolate is an extra 29-nucleotide sequence located at the nucleotide positions between 27,863 and 27,864 (referred to the complete sequence of BJ01) within an overlapped region composed of BGI-PUP5 (BGI-postulated uncharacterized protein 5) and BGI-PUP6 upstream of the N (nucleocapsid) protein. The discovery of this minor genotype, GD-Ins29, suggests a significant genetic event and differentiates it from the previously reported genotype, the dominant form among all sequenced SARS-CoV isolates. A 17-nt segment of this extra sequence is identical to a segment of the same size in two human mRNA sequences that may interfere with viral replication and transcription in the cytosol of the infected cells. It provides a new avenue for the exploration of the virus-host interaction in viral evolution, host pathogenesis, and vaccine development.
