Objective To study the morbidity of cough variant asthma (CVA) among patients with chronic cough syndrome and its relative risk factors. Methods Patients were recruited with detailed history on their illness. Data were collected on physical examination, chest X-ray, eosinophil cell counts, pulmonary ventilation with histamine stimulating test and bronchi dilation test. According to available data, diagnosis of CVA was confirmed and the relative factors Questionnaire form was completed for each patient. Results Among 473 patients with chronic cough, 95 (44 male and 51 female) were confirmed to be CVA (20.08%). Analysis of the relative factors suggested that CVA was associated with multiple factors. Morbidity of CVA was associated with season, personal histories on allergy and family history on asthma, CVA could be induced by upper respiratory tract infection, inhale of oil vapor, acrimony air, over-burdened physical exercises etc. Conclusion For patients with chronic cough symptom, clear diagnosis of CVA, avoid of passable risk factors and timely medical intervention when necessary, would be helpful in controlling clinical courses and improving the prognosis of the disease.

OBJECTIVETo discuss the reasonable choice of the surgical approach to petroclvial tumors.

METHODSThe clinical data of consecutive 53 patients with the petroclival tumors, treated from June 2002 to June 2004, were reviewed to compare the different surgical approaches to pertroclival region.

RESULTSubtemporal transtentorial approach were used in 11 patients, suboccipital retrosigmoid approach in 12 patients, (transzygomatic or orbitozygomatic) frontotemporal (pterional) approach in 12 patients, presigmoid sinus approach in 2 patients, subtemporal and retrosigmoid sinus combined approach in 7 patients, subtemporal anterior petrosal extradural approach in 7 patients and extended transfrontal base extradural approach in 2 patients. Of all patients in this group, total tumor removal was achieved in 32 patients, subtotal in 9, largely partial in 12. The new cranial nerve deficit took place in 16 patients postoperatively, two patients died from coma and serious pneumonia.

CONCLUSIONSUsing perfect microsurgical technique, conventional surgical approaches on petroclival region such as suboccipital retrosigmoid approach, subtemporal transtentorial approach can be suitable for most petroclival tumor with the help of neuro-navigation and neuro-endoscopy. To the epidural tumor on petroclival region, the epidural approach should be used with less invasion to the brain tissue. And to the giant petroclival tumor, the combined-tentorial approach can provide an excellent access and exposure to the tumor.

Objective To explore the effect of long noncoding RNA-ATB (LncRNA-ATB) on phenotypic transition and proliferation of human peritoneal mesothelial cells (HPMCs) induced by high glucose.Methods HPMCs used in experiment were divided into three groups:control group,mannitol group and hypertonic glucose group.HPMCs in control group received no treatment,and in hypertonic glucose group and mannitol group were treated with 50mmol/L D-glucose and isotonic mannitol for 72 hours,respectively.Real-time PCR was employed to detect the mRNA expression of LncRNA-ATB,E-cadherin,α-smooth muscle actin (α-SMA),connective tissue growth factor (CTGF),Cyclin D1,cyclin dependent kinase inhibitor 4 (CDK4),protein 27 (p27)and proliferating cell nuclear antigen (PCNA).Western blotting was performed to detect the proteins expression of E-cadherin,α-SMA,CTGF,Cyclin D1,CDK4,p27 and PCNA,and flow cytometry was used to test the cell cycle.Lentivirus artifice was used to up-or down-regulate the expression of LncRNA-ATB in untreated HPMCs.Real-time PCR was employed to detect the mRNA expression of E-cadherin,α-SMA and CTGF,Western blotting was performed to detect the proteins expression of E-cadherin,α-SMA and CTGF,and flow cytometry was used to test the cell cycle.Results It is revealed by Real-time PCR,Western blotting and flow cytometry that the expressions increased of LncRNA-ATB,α-SMA,CTGF,Cyclin D1,CDK4 and PCNA induced by hypertonic glucose,and decreased of E-cadherin and p27 (P＜0.05).Up-regulation of LncRNA-ATB promoted HPMCs phenotypic transition and proliferation,while down-regulation alleviated HPMCs phenotypic transition and proliferation.Conclusion Hypertonic glucose may accelerate HPMCs phenotypic transition and proliferation by up-regulating the expression of LncRNA-ATB.

OBJECTIVETo investigate the expression of heparin-binding epidermal growth factor-like growth factor (HB-EGF) in patients with gastric carcinoma in different stages.

METHODSThe expressions of HB-EGF protein and mRNA in normal gastric tissues, metaplasic intestinal mucosa, early-stage gastric cancer and advanced-stage gastric cancer tissues were detected by immunohistochemistry and in situ hybridization.

RESULTSHB-EGF expression was only detected in the parietal cells of the gastric fundic glands and in gastrin cells of the pyloric glands in normal gastric tissues. Weak HB-EGF expression was detected in the epithelial cells of the gastric mucosa in intestinal metaplasic mucosa, and the expression increased in all layers of the gastric mucosa in early-stage gastric cancer. Intense HB-EGF expression was observed in advanced gastric cancer.

CONCLUSIONIncreased HB-EGF expression may be implicated in the pathogenesis and development of gastric carcinoma.

OBJECTIVETo observe the anti-renal fibrosis effect of Paidu Baoshen Pill (PBP) on 5/6 nephrectomized rats and to explore its mechanism.

METHODSTotally 50 SD male healthy rats were randomly divided into the normal control group (n = 10), the sham-operation group (n = 10), and the nephrectomy model group (n = 30) according to the proportion of 1:1:3. Rats in the sham-operation group had their renal capsule isolated without nephrectomy. Rats in the nephrectomy model group had their kidneys 5/6 nephrectomized. Then 24 h urine was collected and 24 h urinary protein (24 h UP) detected. Serum blood urea nitrogen (BUN) and serum creatitine (SCr) were also tested. According to the SCr level 30 rats of the model group were further randomly divided into the model group, the PBP group, and the Niaoduqing Granule (NG) group, 10 in each group. Rats in the PBP group and the NG group were respectively administered with PBP (at the daily dose of 1.0 g/kg) and NG (at the daily dose of 3.33 g/kg) by gastrogavage (they were dissolved in distilled water). At the same time, 2 mL distilled water was administered by gastrogavage to rats in the normal control group, the sham-operation group, and the nephrectomy model group, once daily for 4 successive weeks. Mental conditions, activities, hair color, shape of stool, and the body weight were observed during administration. After 4 weeks, urine was collected to detect 24 h UP. Blood was sampled to detect SCr, BUN, transforming growth factor β1 (TGF-β1), type III procollagen (PC III), collagen type IV (Col IV), laminin (LN), and fibronectin (FN). After rats were killed, their left remnant renal tissues were collected for pathological examinations. The protein expression quantity of TGF-β1 and FN was detected by immunohistochemical method. mRNA expression levels of TGF-β1 and FN were detected using real time fluorescent quantitative PCR.

RESULTSThere was no statistical difference in the above indices between the normal control group and the sham-operation group (P > 0.05). Compared with the sham-operation group, rats' general condition was poorer in the model group, their body weight grew slower, and 24 h UP increased; serum levels of BUN, SCr, TGF-β1, PC III, Col IV, LN, and FN increased; the residual renal pathological lesion was serious; expression levels of TGF-β1, TGF-β1, mRNA, FN, and FN mRNA increased in the renal tissue (all P < 0.01). Compared with the model group, rats' general condition was better, their body weight grew faster, 24 h UP reduced (P < 0.05), blood levels of BUN and SCr decreased significantly (P < 0.01), serum levels of TGF-β1, PC III, CoL IV, LN, and FN decreased (P < 0.05, P < 0.01); the residual renal pathological lesion was attenuated in the PBP group and the NG group; expression levels of TGF-β1, TGF-β1, mRNA, FN, and FN mRNA decreased (P < 0.01). Compared with the NG group, blood levels of SCr and FN, and expression levels of FN and FN mRNA decreased more in the PBP group (P < 0.05).

CONCLUSIONSPBP had the effect of anti-renal fibro- sis in 5/6 nephrectomized rats. Down-regulating expression levels of TGF-β1, and FN from gene transcription and protein translation levels might be one of its mechanisms.

Butyrate, normally produced by probiotics in the gut, not only provides energy for cells, but also changes the phosphorylation, acetylation and methylation levels of many proteins in cells. As a result, it affects the expression of many genes and the transmission of cell signals. Through G protein-coupled receptors, butyrate promotes the secretion of intestinal mucus and the formation of epithelial barriers, and attenuates the impacts of the pathogenic bacteria and their metabolites on human body. The Toll-like receptors (TLRs) are a group of pattern recognition receptors, and their activation causes the translocation of nuclear factor κB (NF-κB) from the cytoplasm to the nucleus and eventually leads to expression and secretion of various pro-inflammatory factors and chemokines. The expression of TLRs is also involved in the pathogenesis of some inflammatory diseases and tumors. The purpose of this review is to summarize the effects of butyrate on TLRs and their downstream signaling pathways. We not only summarized the production of butyrate, the expression of TLRs and the influence of their interaction on the body under the conditions of inflammation and tumor, but also discussed the potential role of butyrate as a bacterial metabolite in the treatments of some human diseases.
