Objective To evaluate the standardization of diagnosis and therapy for stage I epithelial ovarian cancer.Methods Retrospective study of 146 cases of ovarian cancer admitted in our hospital. All of cases had postoperative pathological diagnosis.Results 146 cases of epithelial ovarian cancer from Jan 1980 to Jun 2002. 32 of them were stage I cases (21 92%). The average age was 45 32. The first four symptom were self touching the mass, abdomen bulge,abdomen pain and oppress symptoms. All of 29 cases accepted surgery and chemotherapy in our hospitalexcept that 3 cases.4/32 lost touch ,3/32 died of other diseases, 5/32 recurrence, 3/32 died of cancer.Five-year survival rates were 92 87%, ten-year survival rates were 83 90%. Conclusions Prognosis between early and advanced ovarian cancer is obvious difference. If the diagnosis and therapy for epithelial ovarian cancer is early,and survival rates is highly.

OBJECTIVE To investigate the prevalence of strains producing extended-spectrum ?-lactamases (ESBLs) and AmpC ?-lactamases in Pseudomonas aeruginosa,and to supply the laboratory evidence for antibiotic rational application in clinic. METHODS Totally 105 clinical isolates of P. aeruginosa were identified with VITEK-32. Drug sensitivities were determined by Kirby-Bauer methods. ESBLs were detected by double-disc synergy test,and cefoxitin three dimensional test was applied to filter AmpC positive strains. RESULTS Among 105 strains of P. aeruginosa,28 strains (26.7%) were AmpC enzymes positive,20 strains (19.0%) were ESBLs positive,and 5 strains(4.8%)were AmpC+ESBLs positive. The detective rate of producing AmpC ?-lactamases strains was higher than that of producing ESBLs strains. There was significant difference between them. CONCLUSIONS ESBLs and AmpC ?-lactamases are two main enzyme types conferring resistance to ?-lactam antibiotics in clinical isolates of P. aeruginosa. Imipenem can be the first choice for treating infections caused by P. aeruginosa producing ESBLs or AmpC ?-lactamases.

OBJECTIVE To study resistance of Enterococcus in clinical isolates to high-level gentamicin(HLG) and investigate drug resistance of these Enterococcus.METHODS Totally 140 strains of Enterococcus were detected resistance to antibiotics by Kirby-Bauer test and agar-screening test.Data were analyzed using WHONET5.3 software.RESULTS Same result was obtained by two kinds of detecting methods,there were 73 strains of high level gentamicin resistance(HLGR,52.1%) and 67 strains of non-HLGR(47.9%),the resistance rate of HLGR was higher than that of non-HLGR,the isolation rate of vancomycin resistanct Enterococcus was 3.6%.CONCLUSIONS The most common enterococci causing hospital infection are E.faecalis and E.faecium.The drug resistance rate of E.faecium is higher than that of E.faecalis.It is imperative to select the proper method to detect HLGR of Enterococcus,and select proper antibiotic in terms of antibiotic susceptibility test during clinical therapy.

Glycogen synthase kinase-3β( GSK-3β) is a serine-threonine kinase,which was originally identified as a key regula-tor of glycogen metabolism. In nervous system, GSK-3β partici-pates in many central and peripheral nervous system physiological processes through transcription,cell proliferation and differentia-tion. The abnormal activity of GSK-3βinduces downstream signa-ling molecules and gene expression abnormalities,which are in-volved in some neuropsychiatric disorders such as schizophrenia, bipolar disorder,Alzheimer's disease,and pain. In recent years, lots of basic and clinic researches focus on GSK-3β,which might gradually become critical theraptic target of many diseases. The article mainly reviews the mechanisms involved in abnormal acti-vation of GSK-3β related neuropsychiatric disorders.

Objective To study the expression and signiifcance of phospholipid transfer protein (PLTP) and macrophage migration inhibitory factor (MIF) in mice with bronchopulmonary dysplasia (BPD). Methods Ninety-six 4-day-old mice were randomly divided into oxygen group and air group. Mice in oxygen group were exposed to a FiO2 of 65%, and mice in air group were exposed to air. On day 7, 14, 21 and 28, blood and lung tissue samples from 12 randomly selected mice in each group were obtained. The serum levels of MIF and PLTP were measured by ELISA assay. The morphological changes of lung tissue were ob-served with HE staining. Results The mice in oxygen group showed thickened lung parenchyma and obvious pulmonary ifbrosis. The radioactive alveolar count was signiifcantly lower in oxygen group than that in air group (P<0.01). PLTP level in air group was increased gradually from day 7 to day 21, and began to decrease on day 28. PLTP level in oxygen group was increased from day 7 to day 14, and decreased on day 21 and day 28. MIF level in air group did not change during the experiment. MIF level in oxygen group was signiifcantly increased from day 7 to day 21, and began to decrease on day 28. Conclusions MIF and PLTP may be good biomarkers for the diagnosis of BPD.

OBJECTIVE:To study the compatible stability of Cefmenoxime for injection with Ganciclovir for injection in 0.9% Sodium chloride injection and 5% Glucose injection. METHODS:At room temperature,the appearance and pH of the mix-tures were observed after Cefmenoxime for injection was compatible with Ganciclovir for injection. HPLC method was adopted to determine the content of them. RESULTS:No significant change was noted for the mixture in appearance and pH value. The con-tent of ganciclovir was more than 98%,but that of cefmenoxime decreased to 75.33%. CONCLUSIONS:Cefmenoxime for injec-tion can not be mixed with Ganciclovir for injection in 0.9%Sodium chloride injection and 5%Glucose injection .

Objective:To investigate the polymorphism of the (MTHFR) C677T and its correlation with the severity of hypertension in Shanxi Province.Methods:A total of 306 patients with essential hypertension from the Second Hospital of Shanxi Medical University from January 2017 to January 2018 were selected as subjects. The clinical data of these patients were extracted from the hospital information system. The biochemistry index, including homocysteine (Hcy) were collected from the hospital laboratory test system and the polymorphism of MTHFR C677T gene was analyzed by polymerase chain reaction (PCR). Logistic regression analysis was used to estimate the severity of hypertension.Results:The frequencies of CC, CT and TT genotypes in patients with essential hypertension in Shanxi were 22.22%, 47.06% and 30.72. The C677T genotype and allele frequency revealed no signifcant departures from Hardy-Weinberg equilibrium in the population from the Shanxi region. Compared with MTHFR 677CC, MTHFR 677CT and MTHFR 677TT genotypes could increase the severity of hypertension by 2.29-fold and 2.24-fold. Smoking, family history of hypertension , Hcy and TG were independent risk factors for increasing the severity of essential hypertension ( OR=2.04, 1.81, 1.04, 1.26). Conclusions:MTHFR C677T genotype, smoking, family history of hypertension, Hcy and triglycerides could be important genetic and high-risk factors for development of severe hypertension , which will help to identify populations at high-risk of hypertension and may facilitate the development of hypertension control strategies.

Objective To observe left ventricular transmural peak radial strain and strain time-to-peak of peri-infarct different layers myocardium using tissue Doppler strain imaging, to assess its mechanical pattern during acute myocardial ischemia.Methods Left anterior descending coronary artery (LAD) were ligated in experimental open-chest Beagle dog models (n = 9),the two-dimensional apical short-axis views of left ventricle in three complete cardiac cycles were acquired and stored in TDI-Q workstation at baseline(the control group of peri-infarc myocardium) and during acute myocardial ischemia respectively.Sampling volume was uesd to measure the peak radial strain and the strain time-to-peak consesquently on the derived M -mode tissue Doppler velocity images at peri-infarct myocardium before and after ischemic segments and different layers(subendocardium, medium, subepicardium).Statistical analies was performed using student's t- test or Pearson's correlations.Results Peak radial strain decreased at peri-infarct subendoeardium (P<0.05) with no significant difference between those at baseline and at peri-infarct medium (P >0.05), the peak radial strain increasd at peri-infarct subepieardium (P < 0.05) ,and the strain time-to-peak at different layers of peri-infarct myoeardium was significantly postponed (P< 0.05).There was a good correlationship of peak radial strain between subendocardium and segment as well as between the medium and segment (r = 0.617, P<0.01 ; r = 0.556, P<0.01).This correlationship disappeared at peri-infarct myocardial segment (r = 0.287, P > 0.05, r = 0.243, P > 0.05).Conclusions The left ventricular transmural mechanical remodeling at peri-infarct myocardium is the integrant of result of mechanical interactions between ischemic and nonischemic myocardium,which might be one of the trigger the structural and fundational remodeling processes involving in the pathophysiological foundation of ischemie cardiomyopathy.

Objective To examine the levels of serum adipaneetin in patients with incipient chronic kidney disease (CKD, GFR≥ 60ml/min, and identify the relationship between serum adiponectin and albumin (ALB), urinary protein excretion amount, blood lipid and renal function. Methods Forty-two CKD patients and twenty normal healthy persons were involved in this study. These patients were divid- ed into two groups: nephrotic syndrome and non-nephrotic syndrome. The level of serum adiponectin, serum ALB, urinary protein excretion amount, blood lipid, renal function were measured and compared. Results The level of serum adiponectin in nephritic syndrome patients [(21.9±11.3) mg/L] and non-nephrotic syndrome patients [ ( 11.0±7.0) mg/L] was significantly higher than that in normal healthy per- sons[ (5.6±3.3) mg/L] ( P<0.01 ), and the level of serum adiponectin in nephritic syndrome patients was higher than that in non-ne- phrotic syndrome patients( P <0.01 ). Correlative analyses revealed a negatively correlation between serum adiponectin and serum total pro- tein(TP, ALB, BMI( r=-0.5680, r = -0.6241, r = -0.4083,respectively), and a positive correlation between serum adiponectin and urinary protein excretion amount ( r =0.4083). Stepwise regression analyses showed that serum adiponoctin was highly influenced by BMI, ALB and urinary protein excretion amount. Conclusion Serum adipanectin was markedly increased in incipient CKD, especially in patients with macroalbuminura. The effect of high level adiponectin in CKD was still not clear.

Objective To characterize the growth curve of Brucella in Bact/Alert blood culture system which may be helpful to predict the growth of Brucella strain for earlier clinical diagnosis of brucellosis.Methods The epidemiological,clinical and labo-ratory data including growth curve of Brucella were reviewed and analyzed retrospectively for 15 cases of brucellosis as con-firmed by positive serological test and brucellosis agglutination test.Results All the 15 patients had irregular fever and history of animal exposure,even though their clinical feature and signs varied greatly.The growth curve of Brucella in blood culture showed the same chracteristics in the 15 patients,including:the time to positive alarm was about 72 hours,a longer lag phase, shorter logarithmic phase,a shorter vertical axis corresponding to the logarithmic phase,and a flat stable phase.Conclusions The clinical manifestation of brucellosis is variable and non-specific.Lack of awareness of this disease makes the clinicians mis-diagnose it easily.Therefore,blood culture is critical for clarifying the etiology in febrile patients.The growth curve of bacteria during blood culture is useful for early diagnosis of brucellosis and prevention of laboratory infections.
