Objective To investigate the impact factors for temperature of cornea(TOC) and analyse the relationship between TOC and evaporative dry eye. Methods Two hundred and fifty-seven patients(405 eyes) with normal lacrimal secretion received dry eye tests.Patients were divided into positive group and negative group according to the results,and were randomly subdivided into 4 groups with different environment temperature(T) and relative humidity(RH).For all eyes,TOC,body surface temperature(TBS) of forehead and center corneal thickness(CCT) were measured right after blinking.The impact factors for TOC and the differences in TOC between positive group and negative group were analysed.Results TOC was positively correlated with TBS(r=0.89),T(r=0.75) and RH(r=0.60)(P

Objective To evaluate the clinical application of contrast-enhanced digital subtraction MRI in musculoskeletal malignant tumors.Methods Fifty patients with musculoskeletal malignant tumors were scanned by contrast enhanced T 1WI with an injection of Gd-DTPA (0.1 mmol/kg), and digital subtraction was performed between post-contrast-enhanced images and pre-contrast-enhanced images. Musculoskeletal malignant tumors were evaluated by means of a contrast-to-noise ratio (C/Ns). Imaging sign of the musculoskeletal malignant tumors were compared between subtraction MR images and conventional contrast enhanced MR images.Results Contrast-enhanced digital subtraction MR images were better than conventional contrast enhanced MR images. All cases were confirmed by operation or pathology. All the lesions had higher C/Ns on subtraction MR imaging than on conventional contrast enhanced MR images. C/Ns was 109.74?5.10 (?s) for subtraction MR imaging and 23.61?3.16 for conventional contrast enhanced MR images (t=101.51, P

Objective To investigate the incidence and the drug-sensitivity results of mycoplasma infection in genital tract from the gynecological outpatients,in order to provide a laboratory evidence for clinical rational use of drug.Methods The drug sensitiv-ity kit was used for isolation and culture of mycoplasma,reproductive tract secretions samples of 1 067 cases of gynecological pa-tients were collected to do mycoplasma identification and drug sensitivity test.Results In 1 067 samples,the positive rate of myco-plasma were 659 samples,including ureaplasma urealyticum(Uu)positive rate was 72.99%(481/659),mycoplasma hominis (Mh) positive rate was 3.79%(25/659),Uu and Mh positive rate accounted for 23.22%(1 53/659).The drug sensitivity results of 12 kinds of antimicrobial agents showed that single infection Uu was more sensitive to josamycin,doxycycline,minocycline,tetracy-cline,clarithromycin,azithromycin and roxithromycin.Single infection Mh was more sensitive to doxycycline,josamycin,minocycline and tetracycline.Mixed infection of Uu and Mh was more sensitive to josamycin,minocycline and doxycycline.Conclusion The main pathogen isolated from patients infected with plasma in our hospital is Uu,whether single Uu or Uu,Mh mixed infection,there are differences in the sensitivity of antimicrobial,clinicians should use drug rationally according to the conditions of patients and drug sensitivity results to reduce drug resistance rate.

The growth-propagation and decolorization-degradation systems for the model dy e Biebrich Scarlet by Trametes hirsuta were established preliminar ily. It was showed that 30℃ and the static culture were better; the effects of compo nents in culture media on the efficiencies of decolorization and degradation wer e not significant; considering the convenience of observing the changes of dye c o lors and shortenig the culture period, the potato liquid medium had the advantag e of others as a preferable medium for reaction systems of Trametes hirsuta . The decolorization and degradation of all dyes Biebrich Scarlet and Direct Deep Blu e L-3RB, Reactive Blue X-BR, Basic Violet 5BN, and Methylene Blue by Tramete s hirsuta were better.

Objective To investigate the complications of different enteral nutrition in patients after surgery for massive cerebellar infarction,so as to guide rational application of enteral nutrition in patients.Methods Forty-nine patients with massive cerebellar infarction were divided into three groups randomly:conventional nasogastric tube feeding group (group A,n =12),nasogastric tube feeding plus gastric motor drug group (group B,n =18),and nasojejunal tube feeding group (group C,n =19).The incidences of diarrhea,reflux,aspiration,upper gastrointestinal bleeding and aspiration pneumonia within 3 weeks after initiation of enteral nutrition were observed and compared among the groups.Results The incidence of diarrhea showed no statistically significant difference among the 3 groups (x2 =0.092,P =0.955).Compared with group A,the incidences of reflux,aspiration and aspirafion pneumonia were significantly lower in group B and group C (P ＜ 0.05),and lower in group C compared with group B (P ＜ 0.05).Compared with group C,the incidence of upper gastrointestinal bleeding was significantly lower in group C than in group A and group B (x22 =4.748,P2 =0.029;x23 =4.284,P3 =0.038),but the difference between group A and group B was not significant (x21 =0.000,P1 =1.000).Conclusions Because of the unique pathophysiological features in patients after surgery for massive cerebellar infarction,early enteral nutrition by conventional nasogastric tube feeding may be inappropriate.Nasogastric tube feeding plus gastric motor drug may be applied in mild case with short course of disease.Nasojejunal tube feeding may be the approach of choice for enteral nutrition in critical patients with massive cerebellar infarction for its association with lower incidence of complications.

The effects of E-cadherin-transfected neural stem cells (NSCs) transplantation for spinal cord injury (SCI) in rats were investigated. Sixty SD rats were randomly divided into model control group, NSCs group, empty plasmid group and E-cadherin overexpression group (n=15 each). The animal SCI model was established by using the modified Allen's method. NSCs were cultured. Rats in NSCs group were subjected to NSCs transplantation. E-cadherin gene eucaryotic expression vector and pcDNA3.1-E-cadherin were respectively transfected into cultured NSCs, serving as empty plasmid group and E-cadherin overexpression group respectively. At 7th day after transplantation, neurological function of all rats was assessed by Tarlov score. After rats were sacrificed in each group, the number of BrdU and Nestin positive cells was counted by immunohistochemistry. Immumofluorescence method was used to detect the expression of neurofilament protein (NF) and glial fibrillary acidic protein (GFAP). As compared with model control group, the Tarlov score and the number of of BrdU and Nestin positive cells, and the expression of NF and GFAP in NSCs group, empty plasmid group, and E-cadherin overexpression group were increased significantly (P<0.05), and those in the E-cadherin overexpression group were increased more significantly than the other transplantation groups (P<0.05). It was suggested that E-cadherin could be conductive to nerve regeneration and repair probably by promoting the proliferation and differentiation of NSCs.

As the dressings currently used in clinic settings unflat shape in general, they can't be fitted completely on occiput, heel, elbow, knee and other body parts unflat. This paper developed one kind of foam dressing of special shape based on local anatomy. The foam dressing is waterproof and air permeable, it can cover the wound closely enough to prevent bacteria from invasion and infection. With a saturated absorption ratio of 1: 8 or higher, it can keep the wound clean and moisture by absorbing large amounts of wound inflammatory secretions and is almost completely permeable to oxygen and carbon dioxide. Assuring safety and effect meanwhile, it has better outcomes than common dressings in the same application settings.
