Objective: To explore the influence of comprehensive mental intervention on anxiety of women undergoing artificial abortion.Methods:A total of 100 cases of women undergoing artificial abortion first time were selected, who have got pregnant for 6~10 weeks and were appling for termination of pregnancy and without any contraindications in outpatient clinic. They were numbered according to their visiting sequence and were divided into intervention and control group with 50 cases each based on random principle. Comprehensive mental interventions were carried out for women in the intervention group before and during operation but not for women in control group. Then BP, Pulse rate and anxiety (SAS, self-rate anxiety scale) of all cases were measured and pain degree and artificial abortion syndrome of them were evaluated either.Results:There was no statistic significant difference in general data, BP, P and SAS score between the intervention and control group women before intervention. After the intervention, it showed that: ① Incidence (18%)of moderate and severe pain during artificial abortion of pregnant women in intervention group was apparently lower than that of control group (44%,?2=7.9,P

ACEI,ACEII and Xyr1 are transcriptional factors that regulate cellulase gene expression in Trichoderma koningii.In vitro experiments have shown that ACEI and Xyr1 bind to the cbh1 promoter fragment(-304 to-18) and regulate the gene transcription.However,whether ACEII binds to this 287bp fragment is still unclear.To further elucidate the regulatory mechanism of ACEII for cellulase,DNA-binding domains of ACEII from T.Koningii were expressed in E.coli.It could not show binding to the cbh1 promoter fragment(-304 to-18) by electrophoresis mobility shift assays,suggesting that it is Xyr1 but not ACEII binds playing an essential role during induction of cbh1 gene transcription.

Objective To identify the risk factors for early postoperative cognitive dysfunction (POCD) in the elderly patients undergoing spinal surgery.Methods One hundred and fifty ASA Ⅱ or Ⅲ patients,aged ≥65 yr,undergoing elective spinal surgery under general anesthesia,were studied.Venous blood samples were taken at 1 day before operation and 7 days after operation to determine the concentration of serum S-100B protein.Cognitive function was assessed by Mini-Mental State Examination (MMSE) at 1 day before operation and 7 days after operation.The patients were diagnosed as having POCD if MMSEpre-MMSEpost ≥ 3.The patients were divided into POCD group and non-POCD group.Age,body weight,sex,education,type of operations,complications,preoperative TCM syndrome type,MMSE score at 1 day before operation and 7 days after operation,duration of operation,emergence time,and intraoperative blood loss,cardiovascular events,and amount of fluid infused per hour were recorded.The risk factors for POCD were analyzed using multivariate logistic regression analysis.Results Thirty-eight patients developed early POCD (25.3％).The resuhs of logistic regression analysis showed that age ≥ 70 yr,elementary education or below,duration of operation ≥5 b,and the number of hypotension occurred during operation≥3 were the risk factors for early POCD.Conclusion Age≥70 yr,elementary education or below,duration of operation ≥ 5 h,and the number of hypotension occurred during operation ≥ 3 are the risk factors for early POCD in the elderly patients undergoing spinal surgery.

Background Staphylococcus aureus,Staphylococcus epidermidis and Pseudomonas aeruginosa are common pathogenic bacteria in ophthalmology.To seek an optimal antimicrobial method is critical for the prevention of infection.Objective This study was to investigate the antimicrobial efficacy of riboflavin-ultraviolet A (UVA) on Staphylococcus aureus,Staphylococcus epidermidis and Pseudomonas aeruginosa.Methods Ten strains of frozen Staphylococcus aureus,Staphylococcus epidermidis and Pseudomonas aeruginosa were incubated to culture dishes and resuscitated for 2 times.The bacteria were put into bacterial dilution to prepare the suspension of 0.5 Mclntosh concentration and then the suspension was diluted 10-folds.UVA was used to irradiate the culture dishes added 0,0.1％,0.5％ riboflavin for 10,20,30 minutes with the exposure intensities of 1,2,3 mW/cm2,and the optimal bacteriostatic condition was evaluated by measuring the diameters of inhibition zone.Staphylococcus aureus,Staphylococcus epidermidis and Pseudomonas aeruginosa were divided into normal control group,riboflavin group,UVA group and photodynamic therapy (PDT) group (riboflavin+UVA),and colony forming unit was compared among the groups.Results The optional experimental conditions of PDT inactivating microorganisms were determined as UVA wavelength 370 nm,UVA exposure rate 3 mW/cn2,UVA exposure time 30 minutes and riboflavin 0.1％.The colony forming units were decreased in turn in the normal control group,riboflavin group,UVA group and PDT group (F =110.990,190.841,118.197,all at P =0.000).Compared with the normal control group,the colony forming units were significantly decreased in the UVA group (t =14.640,7.550,5.320,all at P＜0.05),and the colony forming units were significantly decreased in the PDT group (t =25.480,14.750,12.920,all at P＜0.05).The colony forming units decreased by 46.4％-50.2％ in the UVA group and 91.6％-96.7％ in the PDT group.There was no significant difference in colony forming units between the normal control group and the riboflavin group(t =0.660,0.470,0.510,all at P＞0.05).Conclusions PDT can effectively inactivate common bacteria in ophthalmology.This result suggests that PDT has a potential in the treatment of microbial keratitis.

Background The study on the classification of fungi is very important for the diagnosis and treatment of fungal keratitis.Identifying the different species of filamentous fungi is a critical factor for the application of anti-fungal drug in treating keratitis.ObjectiveThis report studies the relationship between the genotype of filamentous fungi and the clinical factors.MethodsFifty-two patients with filamentous fungal keratitis determined by clinical and laboratory examination were recruited in Tongren Hospital from January 2006-December 2006.The lesions were graded on the severity of the corneal ulcer and the presence of hypopyon.The filamentous fungal keratitis was treated with topical and systemic administration of anti-fungal drugs or corneal transplantation.The isolates were cultured in potato culture and identified by morphological characteristics based on the Nelson criterion and genotyped by the rDNA ITS method.The clinical data was retrospectively analyzed.ResultsForty-eight species (eubacteria are bacteria,not fungi)of fungus were identified by morphological characteristics,and the filamentous fungi were divided into 4 types based on the phylogenetic relationships within the rDNA ITS of the 52 filamentous fungi.The morphological characteristics and genotype were confirmed in 48 strains of eubacteria and 31 strains of 52 filamentous fungi (90.3%).The 4 groups of fungi were classified by genotype as follows:group 1 represents 22 strains including 20 strains of Fusarium solani and 2 strains of Fusarium oxysporum;group 2 represents 12 strains including 8 strains of Fusarium moniliformis,3 strains of Fusarium proliferatum and 1 strain of Fusarium incarnatum;group 3 represents 5 strains including 1 strain of Fusarium moniliformis and 4 unknown strains;group 4 represents 13 strains including 10 strains of Aspergillus spp.and 3 strains of Alternaria spp.Significant differences were found in the disease duration (P=0.00),inducing cause (P=0.03),ulcer grade (P=0.01)and outcome of the anti-fungal treatment (P=0.035)when compared between group 1 and 2 with group 3 and 4.Conclusion Filamentous fungi that cause keratitis could be correctly identified by sequencing the internal tanscribed spacer of rDNA.There are significant clinical differences among the groups classified by genotype.

ACEI and Xyr1 are two regulators that potentially involve in regulation of cellulases and xylanases formation in Trichoderma reesei, they compete for a binding site in the xyn1 (Xylanase1-encoding) gene promoter. To further investigate the mechanism for the transcriptional regulation of cellulases, DNA-binding domains of both ACEI and Xyr1 in T. Koningii were expressed from E. coli. They both showed bindings to the cbh1 promoter fragment (-304 bp to -18 bp) by electrophoresis mobility shift assays, suggesting ACEI and Xyr1 not only compete for binding to xyn1 promoter but also to cbh1 promoter.

A case of cirrhosis with spontaneous spinal cord hemorrhage is reported. The patient was a 57-year-old male, whose main clinical symptoms were acute onset, sudden progressive decline of lower limb muscle strength, and incontinence. Magnetic resonance imaging+magnetic resonance angiography+susceptibility-weighted imaging of thoracic spinal cord showed that thin strip like equal and slightly high signal could be seen in the spinal cord of T 1WI sequence, a few low signal foci could be seen in the corresponding part of T 2WI sequence, and there was no obvious change in enhanced scanning. Obvious long strip like low signal foci were shown in the spinal cord of susceptibility-weighted imaging, and the range was significantly larger than that of T 2WI sequence. Spinal cord hemorrhage was diagnosed before operation, and no obvious improvement was found after drug treatment. Spontaneous spinal cord hemorrhage was diagnosed after surgical incision.
