To evaluate the effectiveness of applying visual electrophysiological examination, including flash visual evoked potentials ( FVEP ) , flash electroretinogram ( FERG ) , pattrn electroretinogram ( PERG ) , fundus photography, eye B-type ultrasound, optical coherence tomography ( OCT ) , on visual function assessment and retinal disease detection before cataract surgery. METHODS: Visual elctrophysiological examination, fundus photography, eye B-type ultrasound and OCT were applied in 148 cases ( 196 eyes ) . The positive rate was analyzed according to the results of FVEP, FERG ( or PERG ) , fundus photography, eye B - type ultrasound and OCT.RESULTS: ln 148 cases ( 196 eyes ) , vitreous opacities was showed in 165 eyes ( 84. 2%) by eye B - type ultrasound examination, 31 eyes (15. 8%) without access to B-type ultrasound image; success for fundus camera images in 161 eyes (80. 6%), and unable to get image in 35 eyes (19. 4%); the VEP and ERG in 58 eyes (29. 6%) were get valuable, and the VEP and ERG were saw no obvious abnormal in 138 eyes ( 70. 4%); success for OCT image in 167 eyes (85. 2%), without access to OCT image in 29 eyes (14. 8%). CONCLUSlON: Visual elctrophysiological detection, fundus photography, eye B-type ultrasound and OCT can predict the preoperative visual acuity of cataractous patients. A variety of inspection methods complement each other, can further improve detection rate of retinal diseases and other eye disease before cataract surgery.

Objective:To compare the effect of misoprostol respectively with sublingual administration and rectal administration in the treatment of postpartum hemorrhage. Methods:Totally 72 pregnant women were randomly divided into two groups with 36 cases in each. The sublingual group was given misoprostol 600 μg under the tongue immediately after the front shoulder of baby was delivered, while the rectal group was given misoprostol 600μg into rectum deeply. The amount of blood loss in 2 hours and 24 hours after the de-livery and the adverse reactions were compared between the two groups. Results: The postpartum hemorrhageon in 2 hours and 24 hours of the sublingual group was significantly less than that of the rectal group, and the incidence of postpartum hemorrhage in the sub-lingual group was significantly lower than that of the rectal group, and the difference was statistically significant (P<0. 05). After the treatment, the incidence of adverse reactions between the two groups had no significant difference (P>0. 05). However, the incidence of shiver in the sublingual group was significantly higher than that in the rectal group, and the difference was statistically significant ( P<0. 05). Conclusion:The preventive effect of misoprostol with sublingual administration on postpartum hemorrhage after natural vagi-nal delivery is better than that with rectal administration, which is safe and convenient, and worthy of promoted application in clinics.

Objective To compare the diagnostic values of the detection of urine exfoliated cells by FISH and cytology technolo‐gy in bladder urothelial tumor .Methods The combination probes of CSP3/CSP7 and GLPp16/CSP17 were both used in the FISH detection of urine exfoliated cells from suspected patients with bladder urothelial tumor .The urine exfoliated cells were detected by cytology technology at the same time .The sensitivity and the specificity of the two methods were compared .Results The sensitivi‐ty and specificity of FISH for bladder urothelial tumor screening were 92 .5% and 85 .0% respectively ,and those of cytology tech‐nology were 27 .5% and 90 .0% respectively .The sensitivity of FISH was significantly higher than that of cytology technology (P<0 .05) ,however ,the specificity differences between FISH and cytology technology were not statistically significant (P>0 .05) .Conclusion FISH is expected to become a new method for the screening of bladder urothelial tumor .

Objective To observe the clinical effect by using insulin detemir therapy in children and adolescents with type 1 diabetes mellitus(T1DM).Methods Thirty children and adolescents with T1DM were divided into 2 groups to receive Humulin R and Determir(observation group,n =15) or Humulin R and neutral protamine hagedorn (NPH) (control group,n =15)insulin therapy.Daily insulin dose,glycemic variability,incidence of non-severe and severe hypoglycemia events after the institution of insulin therapy were collected.Results The daily doses of insulin were (1.16 ± 0.30) U/kg in the observation group and(1.21 ± 0.35) U/kg in the control group,respectively.There was no clinically important change between 2 groups(t =0.526,P ＞ 0.05).Within-subject variation in fasting plasma glucose was significantly lower in observation group(29％)than that in control group(65％) (t =5.296,P ＜0.01).One case of severe hypoglycemia event occurred in the observation group,but 5 cases occurred in the control group(t =4.863,P ＜ 0.0l).Two cases of nocturnal hypoglycaemia(22:00-7:00) events occurred in the observation group,7 cases occurred in the control group(t =4.506,P ＜ 0.01).Conclusions Institution of insulin detemir therapy is associated with low within-subject variation in fasting plasma glucose and decreased rates of severe and nocturnal hypoglycemia while dose of insulin did not increase.This makes insulin detemir a valuable new tool for the treatment of children and adolescents with T1 DM.

Objective To investigate the molecular mechanisms of cross-resistance to azoles in a clinical isolate of Aspergillus fumigatus. Methods A. fumigatus was isolated from a patient with invasive aspergillosis.Clinical Laboratory Standard Institute M38-A2 broth microdilution method and E-test method were used to determine the minimum inhibitory concentrations (MICs) or minimum effective concentration (MEC) of itraconazole, voriconazole, amphotericin B, posaconazole and caspofungin for the A. fumigatus isolate. DNA was extracted from the isolate and subjected to the amplification of cyp51A gene encoding the target enzyme of azole antifungal agents followed by sequence analysis. Results The broth microdilution test showed that the MEC of caspofungin was 0.5 mg/L, and MICs of itraconazole, voriconazole and amphotericin B were ≥ 16 mg/L,8 mg/L and 1 mg/L, respectively, for this isolate; while E-test assay revealed that the MICs of caspofungin,itraconazole, voriconazole, amphotericin B and posaconazole were 0.047 mg/L, ≥32 mg/L,≥32 mg/L, 12 mg/L and ≥32 mg/L, respectively. Sequence analysis showed an insertion of a 34-bp tandem sequence in the promoter region of the cyp51A gene as well as a T364A point mutation causing the substitution of leucine 98 (L98H). In addition, there were some other mutations in the cyp51A gene of this isolate, such as A137T,G585A, C814A, G836C, T991C and A1350G, which could result in corresponding amino acid substitutions.Conclusions An A. fumigatus strain with cross-resistance to azole antifungal agents is isolated. There is an insertion of a 34-bp tandem sequence into the promoter region as well as a T364A point mutation in the cyp51A gene, which contribute to the cross resistance to azole antifungal agents including itraconazole, voriconazole,and posaconazole. In addition, other mutations causing amino acid substitutions have also been detected in the cyp51 A gene of this isolate.

Objective To investigate the in vitro susceptibility of 16 strains of Exophiala dermatitidis to 6 commonly used antifungal agents. Methods The Glinical and Laboratory Standards Institute (CLSI)M27-A2 protocol was carried out to determine the MIGs of terbinafine (TRB), itraconazole (ITC), amphotericin B (AMB), fluconazole (FLC), voriconazole (VRC), and caspofungin (GAS) to 16 strains of E. dermatitidis, and E-test was performed to determine those of VRG, ITC and AMB. Besides, the minimal fungicidal concentrations (MFGs) of the above antifungal agents to the 16 strains of E. dermatitidis were further assessed.The activity of TRB in combination with ITC and VRG against E. dermatitidis was also estimated. Results The MIC ranges of TRB, VRC, ITC, AMB, FLC, and CAS were 0.125 - 0.25 mg/L, 0.25 - 0.5 mg/L, 2.0 mg/L,2.0 mg/L, 16 - 32 mg/L and 16 - 64 mg/L respectively as shown by M27-A2 microdilution assay, while the MIC ranges of VRG, ITG and AMB, as determined by E-test, were 0.032 - 0.094 mg/L, 0.047 - 0.5 mg/L and 0.125 - 3.0 mg/L, respectively. The MFC ranges of TRB, VRC, ITG, AMB and FLG were 0.125 - 0.5 mg/L,0.25 - 0.5 mg/L, 2.0 - 4.0 mg/L, 2.0 - 4.0 mg/L and 16 - 64 mg/L, respectively. No synergism in the acitivity against E. dermatitidis was observed for the combination of TBR with ITC or VRC. Conclusion E. dermatitidis is susceptible to TRB, ITC, AMB, and VRC, but less sensitive to both FLC and GAS.
