Objective To investigate the clinical value of combined test of prealbumin (PA),total bile acid(TBA)and liver bi-opsy in chronic hepatitis.Methods 172 patients hospitalized with chronic hepatitis in the Affiliated Hospital of Yan’an Uni-versity Medical College from October,2013 to March,2014 was collected as the chronic hepatitis group;and 45 cases of nor-mal healthy control of the corresponding period was collected as the control group.Prealbumin,TBA was detected respec-tively in the two groups.Immunoturbidimetry was adopted in PA,Enzymatic cycling assay was employed in TBA,and at the same time percutaneous puncture of liver histology was detected in the chronic hepatitis group.Results The PA in the chro-nic hepatitis group (179.12±8.46 mg/L)was lower than the control group (257.34±6.38 mg/L),and the difference was statistically significant (P <0.05).The TBA in the chronic hepatitis group (30.58±9.37 μmol/L)was higher than the con-trol group (8.16±1.59 μmol/L)and also the difference was statistically significant (P <0.05).PA was negatively correla-ted with the pathological grades (rs =-0.617,P <0.05),and TBA was positively correlated with pathological grades (rs =0.724,P <0.05).The separate diagnostic positive rate of PA was 58.7% (101/172),while the TBA was 93.6% (161/172).The combined diagnostic positive rate of the two was 93.6% (161/172),it was higher than the separate rate and was statistically significant (P <0.05).Conclusion The serum levels of PA and TBA can reflect the extent and degree of hypo-hepatia and hepatic inflammation,and the combined detection of the two will be much sensitive to the diagnosis of chronic hepatitis,and compared with histological detection,it is convenient,simple,and easy to operate.

Objective To investigate the CT and MRI features of desmoid-type fibromatoses(DF).Methods The images of 29 ca-ses with DF proved by pathology were reviewed retrospectively.CT and MRI examinations were performed in 1 5 cases respectively, and both in 1 case.Results The median age was 33.0 years with a male-to-female sex ratio of 1 ︰ 2.2.36 lesions were discovered,among which 26 cases were solitary while 3 cases had multiple focus.1 9 lesions were extra-abdominal,14 ones in the abdominal wall and 3 ones intra-abdominal.The largest diameter of tumors was 13 -1 75 mm.27 lesions displayed ovoid or elongated shape while 9 ones were irregular .The boundary could be clear or unclear.25 lesions extended along muscle planes with consistent long axis.23 focuses grew aggressively,1 6 of which crossed the muscle clearance,while 13 lesions grew expansively.On CT,20 lesions appeared iso-den-sity or slightly hypo-density compared with normal muscles,mostly homogeneous(1 5/20).Most lesions exhibited gadually moderate or obvious enhancement on post-contrast CT,and the enhancement was homogeneous or heterogeneous.1 7 lesions were found on MRI,which presented signal intensity similar to or slightly higher than that of muscles on T1 WI and most were homogeneous(12/1 7);on T2 WI,all were heterogenous with slightly high or high intensity.All lesions demonstrated obvious enhancement on MRI after contrast administration ,and most were heterogeneous(12/1 7).Sheets or bands of low signal were detected within 1 1 lesions with no enhancement.Conclusion DF has some characteristics on CT and MRI,which are valuable for accurate pre-operative diagnosis,and for evaluation of the lesion extent and involvement of adjacent structures.

Objective To study the change of chromosomal centrimeric dots(Cd)aberration of patents infected by CMV after anti-virus treatment.Methods 22 cases who had spontaneous abortion early and infected by CMV(PCR detection)were studied.We analyzed their blood Cd by simultaneous silver attaining technique before and after treatment by anti-virus medicines respectively.Results The rate of Cd aberration of patients infected by CMV was higher.But after treatment by anti-virus drugs,the rate would decrease gradually(P

AIM: To explore the changes of myocardial energy metabolism and adenine nucleotide translocase (ANT) activity in mitochondria in rats exposed to hypoxia. METHODS: Adult male Wistar rats were exposed to simulated high altitude at 5 000 m for control (0 d), 1 d, 5 d, 15 d, 30 d in hypobaric chamber. Myocardial mitochondria were isolated by centrifugation. Mitochondria respiratory function was measured by Clark oxygen electrode. The size of adenine nucleotides pool (ATP, ADP, AMP) in mitochondria were separated and measured by HPLC. ANT activity was measured by [3H]-ADP incorporation. RESULTS: Compared to control, mitochondria state Ⅲ respiratory (ST_3) and RCR decreased and ST_4 increased sharply at 1 d, 5 d and 15 d, ST_3 still lower than that in control at 30 d, while RCR level restored. ATP contents and ANT activity decreased at 1 d and 5 d, then restored to control level at 15 d, then decreased again at 30 d. CONCLUSION: The inhibition of mitochondria respiratory function is the main reason that makes ATP contents decrease during hypoxic exposure. ANT activity and ATP content change cooperatively.

OBJECTIVE To investigate the distribution and the resistance rate of Shigella in Anhui Province to guide the choice of antibacterials. METHODS Ninety one strains of Shigella were cultured in Sep 2005.The groups were identified by biochemical and serologic tests.Susceptibility of 91 strains of Shigella in Anhui to various antibiotics was tested using standardized custom dilution MIC panels according to CLSI(2005) guidelines. RESULTS There were 57 strains of Shigella flexneri,31 strains of S.sonnei and 2 strains ofS.boydii among 91 strains of Shigella.The resistance rates of Shigella to cefoperazone/sulbactam and piperacillin/tazobactam were remarkably lower than to other third generation cephalosporins.The susceptible rates to carbopenems were 100%.The resistance rates to ciprofloxacin lactate and pazufloxacin mesilate were 27.47% and 32.97%,respectively. CONCLUSIONS There is a certain resistance rate of the Shigella to fluoroquinolones and the third generation cephalosporins.More attention should be paid to the surveillance and control of such resistance.

Objective To explore the effect of insulin subcutaneous pump combined with psychological intervention on gestational diabetes mellitus.Methods A total of 118 patients were enrolled in this study from November 2015 to October 2016 in Lishui central hospital.The patients were randomly divided into the experimental group and the control group according to the time of hospitalization.The experimental group was given insulin subcutaneous pump combined with psychological intervention.The control group was given insulin subcutaneous pump.Results After intervention, the degree of complete compliance in the experimental group was 86.44% and 28.81% before intervention, the difference was statistically significant(P<0.05).Compared with before treatment, blood glucose and glycosylated hemoglobin were decreased after treatment(P<0.05).The incidence of complications in the two groups include: pregnant women with excessive amniotic, neonatal hypoglycemia, pregnancy induced hypertension syndrome and so on.The difference of complication rate between the two groups was statistically significant(P<0.05).Conclusion The timely and accurate psychological guidance of pregnant women with diabetes mellitus can control the blood glucose in the normal range, reduce the occurrence and development of maternal and child complications, and ensure the safe and healthy mother and child health.

Objective To investigate the correlation between recurrent spontaneous abortion and karyotype correlation,and provide reference for clinical diagnosis and treatment of spontaneous abortion.Methods 51 couples peripheral blood lymphocyte were collected and cultured from March 2010 to March 2013 in the region.Karyotype analysis were performed to observe the distribution of the rate of chromosomal abnormalities situation.Meanwhile the correlation between the number of abortions and chromosomes were compared.Results Among the 102 subjects,32 cases(31.37％)of them were found chromosomal abnormalities in RSA.The ratio of polymorphic mutation accounted for 56.25 ％ of the chromosome abnormality.accounting for 17.65 ％ the total.Which was significantly higher than other chromosomal abnormalities(P＜0.05).Among the RSA and chromosomal karyotype cases,females accounted for 68.75 ％,which was significantly higher than males (31.25 ％)(P＜0.05).46XY(Y≥18)has the highest incidence in chromosome polymorphism,accounting for 33.33 ％,while abortions accounting for 30.77 ％.RSA number and incidence of chromosomal abnormalities to miscarriages three times the highest rate of abnormal,accounting for 43.48％.Conclusion Chromosomal abnormalities is an important factor in recurrent spontaneous abortion.Recurrent abortion is not only related to the structure of chromosomes,but also has a certain relationship with the variation of chromosome polymorphism.

Objectives This study was conducted to detect and analyze the presence of plasmidmediated quinolone resistance (PMQR) determinants [qnr,aac-(6′)-Ib-cr and qepA] among clinical isolates of Citrobacter freundii strains isolated from patients in Anhui,China,and to understand the susceptibility of PMQR positive strains to commonly used antimicrobial agents.Methods During the year 2009,31 Citrobacter strains were collected from the First Affiliated Hospital of Anhui Medical University.Polymerase chain reaction (PCR) was used to detect PMQR genes.Amplicons were purified,sequenced and compared with data from the GenBank.Conjugation experiments were conducted to determine whether the qnr-carrying plasmids were self-transferable.The susceptibility of the positive isolates and transconjugants were tested by agar dilution method according to Clinical and Laboratory Standards Institute (CLSI) guidelines.The minimum inhibitory concentrations (MIC) of ciprofloxacin and levofloxacin were determined by E-test strips.Results Among the 31 Citrobacter strains,the qnr genes were detected in 8 isolates (25.8％),among which,6 carried qnrB.Aac-(6′)-Ib-cr and qepA were not identified in these isolates.The qnr genes were transferred from four clinical isolates to their transconjugants.Sequence analysis identified one novel qnrB variant (qnrB24).The resistant rate of qnr-positive clinical isolates to quinolone was 87.5 ％.Most of them were also resistant to various other antibiotics,including cefotaxime (75.0 ％),amikacin (7.5 ％),ceftazidime (62.5 ％),cefapime (37.5 ％),and gentamycin (87.5 ％).All qnr positive strains were susceptible to imipenem.MIC of all transconjugants showed reduced susceptibility to fluoroquinolones,with MIC increased by 10-23 folds.Conclusions Our study shows that qnr gene has occurred in Citrobacter freundii isolates from Anhui Province,China.QnrB is most prevalent in these isolates.Most qnr positive isolates are resistant to commonly used antimicrobial agents.
