Objective To investigate the relationship between vaginal and intestinal Candida in patients with vulvovaginal candidiasis by using microbiological and molecular methods. Methods The samples of vaginal discharge and anal swabs were collected from 148 cases with vulvovaginal candidiasis,followed by fungal culture, identification, purification and genome DNA extraction. The genome sequences from respective locations were aligned and typed according to their homology analyzed by internal transcribed spacer (ITS) PCR and random amplified polymorphic DNA (RAPD) PCR. Patients with vulvovaginal infection or those with infections in intestine and vulvovagina were pooled respectively, while the recurrent incidences after local anti-fungal treatments were analyzed. Results Candida albicans is the dominant pathogen in 148 cases with vulvovaginal candidiasis (91.9% , 136/148) ; 33. 1% (49/148) of patients with vulvovaginal candidiasis were infected in both intestine and vulvovagina. While 92% (22/24) of patients with intestinal and vaginal Candida infection showed high homology. The recurrent rate of patients with vulvovaginal candidiasis complicated with concurrent intestinal Candida infection (7/14) was significantly higher than that of solo vaginal infected patients [21% (6/29)] after vaginal treatment (P < 0. 05) . Conclusions The infection of vulvovaginal candidiasis is highly associated with the concurrent infection of intestinal Candida. The recurrent rate is high in patients with vulvovaginal candidiasis with concurrent infection of intestinal Candida after vaginal treatment. The general management to those patients infected by both vulvovaginal and intestinal Candida is necessary in reducing the recurrence of the disease.

Objective To investigate the expression of insulin-like growth factor-Ⅱ( IGF-II ) and its mRNA in human placenta and to evaluate its role in the pathogenesis pregnancy induced hypertension (PIH). Methods The cellular distribution of IGF-Ⅱin normal and PIH placenta was determined by immunohistochemistry. Trophoblasts were digested,separated,and purified from placenta. IGF-ⅡmRNA expression in trophoblasts was detected by RT-PCR. The mean density was determined by image analysis technique. Results (1) IGF-Ⅱwas mostly found in syncytiotrophoblast,cytotrophoblast and amnio-chorion. The strongest immunoreactivity was observed in the syncytiotrophoblast and cytotrophoblast. (2)The mean density of PIH placenta (0.324?0.042) was significantly lower than that of normotensives (0.360?0.072,P

OBJECTIVE To investigate the expression profile of inflammation related genes in laryngeal squamous cell carcinoma by functional gene chip technique and to probe into the role of correlative genes in pathogenesis of the laryngeal squamous cell cancer and in tumor immunity. METHODS The total RNAs were respectively extracted from two pair samples of laryngeal tumor and the normal tissue around the tumor, and then were reversely transcribed to cDNAs, then synthesized to cRNAs. The cRNAs were labeled with the hybridization probes. The probes were then hybridized with four pieces of inflammation related genes chip. It was chemiluminescently detected and the acquired image was analyzed with special software. RESULTS Forty genes were differently expressed in inflammation related gene profile of laryngeal tumor, among which 22 genes were upregulated and 18 genes were down regulated. Thirteen genes were shown differential expression in both chips with 10 upregulated genes and 3 downregulated genes. CONCLUSION The differently expressed genes in inflammation related gene chips will provide clues and theoretical foundation for the investigation of the relationship between tumor and inflammation, and also the immune pathogenesis of laryngeal tumor. Furthermore CCL-7 may have an important role in the occurrence of laryngeal cancer, and the role of immunity of the pathogenesis of laryngeal tumor needs further studied.

Objective To establish a mathematical model for describing and predicting the effectiveness of physical therapy on lumbar disc hernation(LDH).Methods Daily comprehensive physical therapy interventions including lumbar traction,mobilization and physical agents were administered to 31 LDH patients for 10 sessions.A visual analogue scale was used to measure the pain intensity before each session.The logistic curve model was used in the regression analysis.The first 2 to 9 pain measurements were involved in different predictive models,and the predictive results were compared among different models.Results In regression analysis,the global R2 was 0.719.In predicting analysis,the more measurements involved in the predictive model,the more effective the prediction.The predictive power was low when the model included less than 4 measurements.the prediction power was high when more than 5 measurements were used in the model.Conclusion The logistic model can describe and predict the effectiveness of multiple physical therapy on LDH patients.

Objective To investigate the expression of activating receptors (NKG2D and NKp46), inhibitory receptors (NKG2A and KIR) as well as costimulatory molecules (OX40, 4-1BB and ICOS) on peripheral blood natural killer (NK) cells from patients with recurrent genital herpes (RGH). Methods Four-color immunofluorescence staining with flow cytometry was used to detect the expression of NKG2D, NKG2A, KIR and NKp46 in 44 patients with RGH and 40 normal human controls, and to detect the expression of OX40, 4-1BB and ICOS in 29 patients with RGH and 29 normal human controls. Results The proportions of NKG2D-positive and NKp46-positive NK cells significantly decreased in patients with RGH than those in the normal human controls [(93.3 ± 5.4)% vs (96.9 ± 2.5)%, (88.9 ± 8.7)% vs(93.4 ± 4.1)%, respectively, both P < 0.01]. Between the patients and controls, no significant difference was observed in the expression of NK cell inhibitory receptors, NKG2A [(41.8 ± 14.4)% vs (46.0 ± 14.7)%, P > 0.05] or KIR [(68.3 ± 19.1)% vs (69.1 ± 17.6)%, P > 0.05]. A lower expression of costimulatory molecule OX40 was noted in NK cells from patients with RGH compared with those in normal controls [(1.0 ± 1.1)% vs (1.8 ± 1.7)%, P < 0.05]. Conclusions Herpes simplex virus infection could down-regulate the expression of NK cell activating receptors and costimulatory molecules, subsequently suppress the activation of NK cells, and lead to the escape of virus-infected cells from the killing of NK cells.

Simplified interspecies nuclear transfer in mouse and bovine and the possibilities of the embryos reprogramming were developed. The zona and nucleus of the bovine oocyte were removed by pronase and bisection method respectively. When the skin fibroblast of mouse was fused with the nucleus-free oocyte of the bovine using 40?s and 1. 5 kv/cm direct current pulse, the rates of fusion and cleavage were 67. 44% and 30.23% respectively. Reconstructed heterogenous embryos finally developed to 8-cell stage when they were previously activated by ionomycin and 6-DMAP and subsequently cultured in press-made micro-well in the drop of the medium. Zona-free bisection method could be used for mouse heterogenous embryos cloning, and the micro well culture method could be used to avoid zona-free embryos aggregation.

AIM:To discuss the related factors that affected the stability of posterior corneal surface after laser in situ keratomileusis ( LASIK) .
METHODS:About 64 patients (64 eyes) were enrolled. The correlation among the changes in posterior corneal surface 6 month after LASIK, surgery method, corneal flap thickness ( FT ) , ablation thickness ( AT ) , postoperative residual corneal stroma thickness ( RCST ) , preoperative thinnest corneal thickness ( CT ) , flap thickness/preoperative thinnest corneal thickness ( FT/CT ) , ablation thickness/preoperative thinnest corneal thickness ( AT/CT) , postoperative residual corneal stroma thickness/preoperative thinnest corneal thickness ( RCST/CT) , anterior and posterior preoperative corneal height, the difference of the forward shift in posterior corneal surface ( diff value ) of preoperative and preoperative intraocular pressure were analyzed.
RESULTS: The changes of diff value between preoperative and postoperative were related with diopter (r=0.419, P=0.014), AT (r=0.394, P=0.023), AT/CT (r=0.501, P=0.004), Diff value of preoperative (r=0.501, P=0. 004), RCST (r=-0. 385, P=0. 033) and RCST/CT (r=-0. 401, P=0. 025). The changes of height value from posterior corneal surface between preoperative and postoperative were related with diopter (r=0. 520, P=0. 002), AT (r=0.504, P=0. 003), AT/CT (r=0. 442, P=0. 013), Diff value of preoperative (r=0. 624, P=0. 000) and RCST/CT (r=-0. 394, P=0. 028).
CONCLUSION: AT, RCST, AT/CT, RCST/CT and diff value of preoperative should be the key index that predicted the stability of posterior corneal surface after LASIK,the further research will give the range of safety value.

Sleep disorders are commonly occurred among patients with Parkinson's disease,such as difficulties in the initiation of sleep,fragmented sleep,sleep behavior disorder and excessive daytime sleepiness.The mechanism of sleep disorders associated with Parkinson's disease is not clear,which may be associated with the injury of brain stem,nuclei of median raphe,nuclei fasciculi solitarii,thalamencephalon and the changes of neurotransmitters as dopamine,hypocretin(orexin) and melatonin.This article gives an overview of the mechanism of sleep disorders associated with Parkinson's disease.

OBJECTIVE: To investigate whether the allergic factors impact the severity of chronic rhinosinusitis or not, further more, to explore the relationship between allergic rhinitis and chronic rhinosinusitis. METHOD: A retrospective review was done on 103 patients. All of these patients were under functional intranasal endoscopic sinus surgery after expectant treatment is ineffective. We devided the patients into different groups according to the result of skin prick and specific IgE and if there is difference in VAS score, Lund and Kennedy endoscopic score, Lund-Mackay CT score between the groups. We also analysed the symptoms in different chronic rhinosinusitis patients allerged to variant kinds of allergen. The SPSS 17.0 software was used to analyze the data. Statistical analysis was performed by t-test, rank order test or χ2 test. RESULT: The duration of the disease, VAS score of nasal blockage, score of Lund-Mackay CT and Lund and Kennedy endoscopic before the operation were in no statistical sense after when compared with the two groups of patients with chronic rhiriosinusitis who grouped according the result of skin prick and specific IgE. The VAS score of facial pressure and loss of smell was higher in patients with chronic rhinosinusitis which the skin prick and specific IgE were positive. The VAS score of nasal discharge was higher in patients with chronic rhinosinusitis who got negative skin prick and specific IgE result. The symptoms of chronic rhinosinusitis improved with operation no matter the group of skin prick and specific IgE positive or negative and VAS score of nasal blockage improved significantly in negative group. The symptoms of sneezing, rhinorrhoea and rhinocnesmus improved after operation among the chronic rhinosinusitis patients with skin prick and specific IgE. The number of cockroach allergy is larger among the patients with chronic rhinosinusitis without polyps than the one among the patients with chronic rhinosinusitis with polyps. CONCLUSION Allergic factor didn't impact much the severity of chronic rhinosinusitis patients who were failed in expectant treatment, besidesthe postoperative outcomes showed that only influence the severity of nasal discharge, facial pressure and loss of smell. Different kinds of allergen were found between the patients of chronic rhinosinusitis with or without polyps. No significantly functional endoscopic sinusitis sugrery outcome were related to the allergic factor. But the allergic factor may interfere the remission of nasal discharge after surgery.
