Objective To establish a diagnosis method for fungal infection using two-round PCR,and to evaluate its sensitivity in the detection of clinical specimens suspected to be infected with fungi.Methods A total of 29 specimens of clinical sputum and alveolar wash solution were collected from patients with suspicious fungal infection.All specimens uaderwent direct microscopy with 10%KOH,fungal culture,one-round PCR and two-round PCR.The fungal universal primer targeting ITS regions of rDNA was used in PCR.The detection rate for fungi was compared between these methods.Results The detection rate for fungi was 20.69%by direct microscopy,37.9%by fungal culture,17.2%by one-round PCR,and 48.3%by two-round PCR.More than one species of fungus were detected in 6.9%(2/29),3.4%(1/29)and 24.1%(7/29)of these specimens by fungal culture.one-round PCR and two-round PCR, respectively.There was a significant difference in the detection rate between two-and one-round PCR(x2=6.34,P＜0.05).With regard to the detection rate for more than one species of fungus,two-round PCR was significantly higher than one-round PCR and fungal culture(x2=4.09,6.30.bom P＜0.05).Conclusion Two-round PCR may help to improve the sensitivity of molecular diagnosis of fungus-infected specimens.

Objective To investigate the changes of inositol 1,4,5-triphosphate receptor typeⅠ(IP3RⅠ)expression in the myocardial tissue of rats with endotoxic shock and probe the possible mechanisms of myocardial depression.Methods Thirty-three male Wistar rats were divided into four groups:control group (n=6) were injected normal saline(4ml/kg),and the other 3 groups (n=9) were injected endotoxin via femoral vein with a different dose of 10mg/kg,5mg/kg,and the artificial sacrificed group(10mg/kg,the rats were sacrificed when the mean arterial pressure was first rapidly decreased,then gradually increased to the normal level).IP3RⅠexpression in the myocardial tissue of rats was detected by immunohistochemistry,Western blot and colloidal gold immunoelectron microscopy technique.Results IP3RⅠexpressions were increased significantly in each group of rats with endotoxic shock than in the control group (P<0.01),and most obviously enhanced in the the artificial sacrificed group.The expression of IP3RⅠwas related to the level of mean arterial pressure.Ectopic expression of IP3RⅠwas observed around the cell membrane of the cardiac myocytes.Conclusion (1)The expression of IP3RⅠenhances in the myocardial tissue of rats with endotoxic shock,and exists ectopic expression.(2) The expression of IP3RⅠwas related to the level of mean arterial pressure.(3) IP3RⅠ may be related to the cardiac contractility and involved in the regulation of mean arterial pressure.

OBJECTIVE: To investigate the clinical characteristics of ocular symptoms in patients with allergic rhinitis (AR) and the impact of the ocular symptoms on patients' quality of life. METHOD: AR patients' history and clinical data were collected and analyzed. One hundred cases were extracted from adult patients with and without ocular symptoms in each group and their quality of life were evaluated using rhino-conjunctivitis quality of life questionnaire (RQLQ). RESULT: Totally 1119 cases were collected and 859 cases had ocular symptoms. Of the patients with ocular symptoms, 582 cases were mild, 234 cases were moderate, 43 cases were severe. Eye itching was the most common symptom, followed by tears, hyperemia and swelling. Patients with ocular symptoms had longer disease history than non ocular symptom group (P < 0.05). There was a positive correlation between ocular and nasal symptoms (P < 0.01); patients with ocular symptoms had more severe nasal symptoms than patients without ocular problems; while patients with moderate to severe AR had more severe ocular symptoms than mild AR patients (P < 0.01). Female patients had higher incidence (P < 0.05) and ocular symptoms score (P < 0.05) than male. Children less than 10 years old had a relative lower incidence and score of ocular symptoms. While the incidence and score had an increasing trend for patients older than fifty. There was no difference regarding the type and number of allergen in the patients with and without ocular symptom. Moreover, patients with ocular symptoms had higher scores in the domains of non-nose/eye symptoms, practical problems, ocular symptoms, emotional function and total score in RQLQ than patients without ocular symptom. CONCLUSION It was common for the AR patients to have ocular symptoms, and ocular symptoms had obvious influence on the patients' quality of life. So controlling of the ocular symptoms should not be ignored during the diagnosis and treatment of AR.

BACKGROUND:Our preliminary studies have shown that basic fibroblast growth factor can induce the differentiation of bone marrow mesenchymal stem cells into disc cells of the temporomandibular joint, and for basic fibroblast growth factor, 10μg/L is superior to 5μg/L in col agen synthesis.
OBJECTIVE:To observe ultrastructural changes of bone marrow mesenchymal stem cells after being induced by different concentrations of basic fibroblast growth factor.
METHODS:We cultured primary sheep bone marrow mesenchymal stem cells and selected passage 3 and 4 cells at good growth state. Bone marrow mesenchymal stem cells were stimulated with 5 and 10μg/L basic fibroblast growth factor and their growth state was observed under inverted phase contrast microscope. Uninduced cells served as controls. The slides with cellcrawling pieces were stained with Safranin O, picrosirius and type I col agen immunohistochemistry at days 7, 14 and 21, respectively. Simultaneously we col ected the cells at day 21 to observe the ultrastructural changes of bone marrow mesenchymal stem cells.
RESULTS AND CONCLUSION:After being induced with different concentrations of basic fibroblast growth factor, bone marrow mesenchymal stem cells were able to differentiate into disc cells of the temporomandibular joint;and after being induced with 10μg/L basic fibroblast growth factor, cells were more like fibroblast-like cells of the temporomandibular joint disc. These findings indicate that bone marrow mesenchymal stem cells have morphological basis for differentiation to the fibroblast-like cells of the temporomandibular joint disc.

Objective To evaluate the clinical value of sentinel lymph nodes (SLN) in predicting pelvic lymph node status for early cervical squamous cell carcinoma,and approach the clinical significance of SLN detection for guiding radical abdominal trachelectomy (RAT).Outcomes of follow up and fertility were also observed.Methods A total of 31 patients with stage Ⅰ a2-Ⅰ bl squamous cell carcinoma planned to be given RAT and pelvic lymphadenectomy were enrolled.99mTe-labeled phytate was injected before surgery.Intraoperatively,SLN were identified,excised,and submitted to fast frozen section.Systematic bilateral pelvic lymphadenectomy was performed,and then RAT was performed in patients with negative SLN.All nodes were sent for routine pathological examination and immunostained with anti-cytokeratin antibody to detect micrometastases.Results SLN were detected in all patients (100％,31/31).A total of 109 SLN were identified with a mean number of 3.5 per patient.Of these,SLN of 2 patients were positive on frozen sections and proved to be metastasis by final pathologic examination and quitted the RAT.No missed micrometastasis was found using immunohistochemical staining in SLN and other lymph nodes using histologically node-negative cases.No false negative cases was found and the negative value was 100％ (31/31).The sensitivity,accuracy,and false negative rates were 100％,100％,and 0,respectively.Perioperative complications occured in 5 patients including 2 cases of bladder injury and 3 cases of uterine artery injury.No relapses occurred during follow-up.Five of 19 patients with procreative desire conceived pregnancies (4 spontaneous abortion and 1 premature birth) after surgery.Conclusions The identification of SLN using 99mTc-labeled phytate could predict the pelvic lymph node status in early stage cervical cancer.Under the guidance of SLN detection,RAT is a feasible operative modality with well prognosis and low complications for young patients who desire to preserve reproductive function.
