OBJECTIVETo observe the clinical efficacy of comprehensive Western medical treatment plus Compound Yindan Decoction (CYD) in treatment of acute cholestatic hepatitis (ACH).
METHODSUsing randomized controlled study, 60 ACH patients in line with inclusive criteria were randomly assigned to the treatment group (treated by comprehensive Western medical treatment plus CYD) and the control group (treated by comprehensive Western medical treatment alone), 30 in each group. Scores for symptoms and levels of liver functions [total bilirubin (TBIL), direct bilirubin (DBIL), alkaline phosphatase (ALP), glutamyl transpeptidase (GGT), total biliary acid (TBA)] were observed before and after treatment.
RESULTSCompared with before treatment in the same group, total scores for symptoms decreased in the treatment group and the control group at the end of the 1st and the 4th week after treatment (all P < 0.05). Compared with the control group, total scores for symptoms decreased in the treatment group at the end of the 1st week (P < 0.05). Compared with before treatment, serum levels of TBIL, DBIL, ALP, GGT, and TBA all decreased in the two groups at the end of the 4th week after treat- ment (P < 0.01). Compared with the control group, serum levels of TBIL, DBIL, ALP, GGT, and TBA all decreased in the treatment group at the end of the 1st and the 2nd week after treatment (P < 0.05). Compared with the control group, the average time for TBIL and DBIL decreasing to the level less than five times the normal value was significantly shorter in the treatment group (P < 0.05).
CONCLUSIONCYD could significantly improve clinical symptoms of ACH patients, decrease serum levels of TBIL and DBIL, reduce serum levels of ALP, GGT, and TBA, obviously improve cholestasis, and promote the recovery.

Objective To demonstrate the value of eombined application of prenatal ultrasonography with fetal magnetic resonance imaging(MRI) in the diagnosis of monochorionic muhifetal realformations. Methods Fourteen cases of muhifetal malformations,detected by prenatal ultrasonography,received MRI within 48 h afterwards.All diagnosis were confirmed after delivery or mid-term termination.All imaging results of the 14 cases were retrospectively reviewed. Results Among the 14 cases,there were 7 acardias,5 Conjoined twins and 2 demise of multifetuses.Comparing ultrasound with MRI,we found that:(1)In cases with acardia and demise of multifetusea,ultrasound could diagnose correctly and be an important tool for follow-up,while MRI could demonstrate organs and structures of the acardiac recipient more clearly and detect the secondary changes of brain in the donor and survived fetus.(2)In Conjoined twins,ultrasound was superior to MRI in demonstrating the structure and function of cardiovascular system : and equivalent to MRI in identifying stomach,kidney,bladder and limbs;but inferior to MRI in identifying esophagus,lung,liver and intestinal,especially in the brain. And MRI could demonstrate two fetuses and the relationship between them in COnjoined twins simultaneously. Conclusions Prenatal ultrasonography and MRI have their own advantages and disadvantages in diagnosing monochorionic multifetal malformations.But the combination of prenatal ultrasonography and fetal MRI may be more valuable.

OBJECTIV:
e To find the correlation between real best corrected visual acuity (BCVA) and testing results of microperimetry and visual evoked potential (VEP) and to explore a new method in recording BCVA in macular disease.
METHODS:
Sixty-two patients with macular disease (macular disease group, 62 eyes) and eighteen healthy volunteers (control group, 36 eyes) had BCVA, microperimetry and VEP recorded.
RESULTS:
(1) By microperimetry, the values of retinal mean sensitivity and fixation percentage in macular disease group were lower than that in control group. The bicurve ellipse area in macular disease group was higher than that in control group. By VEP, P100 amplitude under 0.5 cpd and 2 cpd in macular disease group were significantly higher than that in control group and the latency was prolonged (P < 0.05). (2) In macular disease group, BCVA had significant positive correlation with retinal mean sensitivity, bicurve ellipse area, macular central 2 degrees and 4 degrees fixation percentage, respectively (P < 0.05). There was a significant correlation between retinal mean sensitivity and P100 amplitude (P < 0.05). (3) Multiple linear regression equation was y = 0.053 x1+0.008 x3+3.897 (y was BCVA, while x1 was retinal mean sensitivity and x3 was P100 amplitude under 2 cpd).
CONCLUSION
Combined use of microperimetry and VEP is useful in the assessment of BCVA in macular disease.

Objective To investigate the distribution and antimicrobial resistance profile of clinical gram-negative bacterial isolates in the First Afifliated Hospital of Nanjing Medical University during 2014.Methods Bacteria identiifcation was performed by API system or the VITEK-2 Compact automatic identiifcation system. Disk diffusion susceptibility testing or VITEK-2 Compact automatic identification system was used to determine the susceptibility to antimicrobial agents. All data were analyzed using WHONET 5.6 software.Results Among the total 7 931 clinical isolates in 2014, gram-negative bacteria accounted for 64.2% (5 088/7 931). The top three pathogens wereE. coli,A. baumannii andK. pneumoniae. Notably, during the year 2014, 195 strains of carbapenem-resistantEnterobacteriaceaewere isolated, about 6.9% of all theEnterobacteriaceae isolates. Meanwhile, 613 (66.5%) strains of multiple drug resistantA. baumannii and 197 (28.7%) strains of multiple drug resistantP. aeruginosa were isolated.Conclusion During the year 2014, the resistance of the gram-negative bacteria in this hospital is mainly characterized by carbapenem-resistantEnterobacteriaceae, multiple drug resistant A. baumanniiand multiple drug resistantP. aeruginosa. Surveillance of antimicrobial resistance is beneifcial for rational use of antibiotics.
