Dysentery is one of the digestive system diseases, which has a higher incidence rate. The aim of present study was to further explore the incidence of dysentery and get the better prevention of this disease. The data were collected and statistically analyzed from Shaanxi Province for the monthly incidence of dysentery in 22 years. In addition, according to the Yunqi theory and related incidence of diseases, the correlation between the incidences of dysentery and Suiyun, Sitian, Zaiquan and Six-qi were summarized systematically. This study provides a reference for the incidence of dysentery.

Six cases of Paget′s disease of bone, including 5 males and 1 female, aged (57. 7 ±11. 8) years old, were recruited. Mean duration of disease was (7. 5±6. 5) years. Clinical manifestations were bone pain and bone deformity. The lesions mainly reside in the pelvis and femur. X-ray film showed typical lesion of Paget′s disease of bone, such as impaired bone trabecular structure with coarseness and disorder, cortical thickening, medullary cavity narrowing and skeletal deformation. Bone scan revealed abnormal radionuclide concentration in the involved bone. Serum alkaline phosphatase ( ALP) in 6 patients was increased ( median 235 U/ L). 5 patients received zoledronic acid sodium intravenous infusion therapy. Bone pain was relieved obviously in 5 patients after treatment for 2-3 months. Physical activity was greatly improved, and serum ALP levels significantly decreased.

A 47-year-old Chinese man with hypophosphatemic osteomalacia suffered from bone pain, difficulty in walking and pseudo-fractures. Biochemical examination showed a lowered serum phosphorus level and an elevated alkaline phosphatase level. The X-ray examination showed pseudo-fractures of multiple ribs, low bone density, biconcave deformities of the lumbar vertebrae, and pseudo-fracture of the right superior ramus of the pubis. A diagnosis of hypophosphatemic osteomalacia was made. The case was treated with oral neutral phosphate solution, calcitriol and Caltrate D. After treatment for two years, biochemical indicators were improved, and pseudo-fractures healed. Clinically, hypophosphatemic osteomalacia is often overlooked or misdiagnosed. In addition, the duration and dosage of these drugs should be appropriate, in order to avoid tertiary hyperparathyroidism or poor response to treatment.

Objective To study the prognostic value of left ventricular endocardial pacing in percutaneous transluminal septal myocardial ablation(PTSMA)in patients with hypertrophic obstructive cardiomyopathy(HOCM).Methods Fifteen HOCM patients with resting left ventricular outflow gradient(LVOTG)≥30 mmHg and/or stress LVOTG≥50 mmHg were included in this study.Left ventricular endocardial pacing was attempted in the patients 20 minutes before PTSMA.Heamodynamic parameters and LVOTG were monitored during operation and follow up echocardiography was performed 1 month after the operation.Results The mean chickness of the ventricular septals decreased from 22.07?7.85 mm before PTSMA to 17.39?5.79 mm 1 month afterwards(P

Objective To investigate the resistance of Salmonella enterica serotype Typhimurium (STM) to quinolone. Methods A total of 33 salmonella typhimurium resistant to Ciprofloxacin in stool of outpatients from July 1st. 2004 to Oct 31st was isolated. in four hospitals in Wuhan. Antimicrobial susceptibility test was conducted by the Agar Dilution method. All of the strains were studied for the occurrence of mutations in the genes coding for QRDR by PCR and REP-PCR. Results The sequencing of QRDR of these genes in highly quinolone-resistant mutants (MICs of 4 to 16?g/ml) of the 25 STM revealed the presence of gyrA mutation, and inserted base in the gyrB and parE genes were found only in 5 STM. With aid of REP-PCR, the 32 strains were divided into 9 profiles which were correlated to the antibiotic susceptibility spectrums. Conclusions The resistance of STM from community acquired infection in WuHan is very severe. The resistance mechanism was associated with mutations of the quinolone resistance-determining regions. It suggests an outbreak in the community.

Objective To explore the possible upstream signal transduction mechanisms responsible for the decrease of glucocorticoid receptor (GR)α/GRβ in chronic rhinosinusitis (CRS) in vitro. Methods The GRα/GRβ decrease cell model was established by IL-1β-induced human nasal epithelia (HNE) in vitro. Changes in the protein and mRNA expression of GRα, GRβ and the key enzymes in the p38MAPK and NF-κB pathways were measured respectively, before and after being induced with different doses of IL-1β and specific inhibitors of p38MAPK and NF-κB. Analysis of variance (ANOVA) was used to analyze the data. Results With IL-1β-induction, the GRα/GRβ ratio declined in both a time-dependent manner and a concentration-dependent manner in HNE, which demonstrated the successful establishment of a GRα/GRβ decrease model in vitro. After cultured HNE were induced with the same set of IL-1β, the p38MAPK and NF-κB signal pathways were also activated. Either a specific inhibitor (SB203580) of the p38MAPK pathway or a specific inhibitor (PDTC) of the NF-κB pathway increased the GRα/GRβ ratio at the meantime of inhibiting their pathways. The expressions of phospho-NF-κBp50 and phospho-NF-κBp65 were significantly decreased by SB203580. PDTC had no influence on the expression of the key enzymes in the p38MAPK. Conclusion The decrease of GRα/GRβ ratio in HNE induced by IL-1β in vitro is induced through the p38MAPK/NF-κB signal pathways.

Objective To identify the spatial distribution of stray radiation from mobile CT head scanning for the purpose of radiation protection.Methods The head series of CareTom mobile CT were scanned and the radiation dose was measured using TLD (LiF:Mg,Cu,P).The isodose maps of radiation dose field were plotted using Matlab software.Results Radiation dose in the front of the mobile CT was slightly higher than that in the back.The maximum value of 0.255 mGy was found to be at 0.5 m from the scanning hole center.Conclusions The stray radiation dose from mobile CT head scanning was relatively low.However in order to avoid the damage to the operators and other medical workers from long-term low dose exposure,it should keep 2 m away from mobile CT,beside or behind,when in operation.

Objective:To investigate the strategies and methods of pancreatic cancer immunotherapy adopt cytotoxic T lymphocytes activated by dendritic cells(DCs),which modified by heat shock protein 70 peptide complex(HSP70-PC).Methods:HSP70 peptide complex from lumps of tumor-bearing mouse innoculated with pancreas cancer cell(MPC83)were purified by ConA-Sepharose and ADP-Agarose affinity chromatography.Dendritic cells derived from normal murine bone marrow were induced by GM-CSF and IL-4.MTT method was applied to analyses the proliferation activities of DCs.To achieve the specific T lymphocyte cells,DCs modified with HSP70 peptide complex were coculture with murine spleen lymphocytes for 48 hours.Then these activated lymphocytes were cocultured with MPC83 at ratio of effect-target 10∶1 and 20∶1 in vitro and the killing activities were detected by MTT method.Results:High purify HSP70-PC was obtained;104 DCs need 50～100ng of HSP70-PC to modify,100?g of HSP70-PC peptide complex can be extracted from per 1g lump;T cells stimulated by HSP70-PC modify DCs showed more specific cytotoxic activity to MPC83 than lymphocytes activated by DCs without HSP70-PC in vitro.Conclusion:We can extract high purity HSP70-PC for clinical individual immunotherapy from pancreatic cancer lump by using hypobaric affinity chromatography;DCs vaccine modified with HSP70-PC has significant kill effect against pancreatic cancer cell in vitro.
