Objective To explore exenatide in the treatment of metformin(MET)alone,sulfonylurea (SU)alone or MET + SU combination therapy with poor glycemic control in type 2 diabetic pa-tients and to find effective nursing measures.Methods 24 patients were randomly divided into the con-trol group and the exenatide group with 12 patients in each group.In the exenatide group,exenatide 5μg twice a day for 4weeks,then 10μg twice a day for 12 weeks.Changes of HbAlc,body weight,BMI,FBG,P2hBG,and rate of adverse reaction were compared between two groups.Results Glycosylated hemoglobin (HbAlc),body weight,BMI,FBG,P2hBG in the control group before and after treatment showed no significant difference,while the exenatide group showed better results compared with those before treatment and the control group.Nursing intervention played evident effect on reducing adverse effect such as nausea,vomiting,diarrhea,low blood sugar,headache.Conclusions For patients with type 2 diabetes,using MET,SU alone or MET + SU combination therapy showed poor results of blood sugar control,addition of exenatide therapy can effectively control blood sugar,nursing intervention can significantly alleviate the adverse effects of patients.

OBJECTIVETo investigate the effects of Morina Officinalis How (MOH) on the abnormal levels of serum luteotrophic hormone (LH) and LH receptor (LHR) in the testis tissue induced by cellphone radiation (CPR) in rats.

METHODSFifty adult male SD rats were randomly divided into five groups of equal number: sham CPR, untreated CPR, negative double distilled water (DDW) control, aqueous MOH extract, and alcohol MOH extract. All the animals were exposed to mobile phone radiation except those of the sham CPR group. Then, the rats of the latter two groups were treated intragastrically with MOH at 20 g per kg of the body weight per day in water and alcohol, respectively. After 2. weeks of treatment, all the rats were sacrificed for measurement of the levels of serum LH and LHR in the testis tissue.

RESULTSThe levels of serum LH and LHR were 30.15 ± 8.71 and 33.28 ± 6.61 in the aqueous MOH group and 0.96 ± 0.06 and 0.94 ± 0.08 in the alcohol MOH group, both significantly decreased as compared with the negative DDW controls (P < 0.05), but with no remarkable difference between the two MOH groups (P > 0.05).

CONCLUSIONMOH can improve CPR-induced abnormality of LH and LHR in adult male rats.

OBJECTIVETo summarize the clinical features of idiopathic premature ovarian failure (POF) and explore the early diagnosis and intervention.

METHODSA retrospective study was conducted in 39 women with idiopathic POF treated between February, 2009 and January, 2010. The clinical data of the patients including the menstrual feature, POF incidence, vaginal ultrasound and pregnancy outcomes were investigated.

RESULTSOne patient had primary amenorrhea and 38 had secondary amenorrhea with an average duration of amenorrhea of 5.82 years. Abrupt cessation occurred after 1-2 menstruations following the menarche in 2 cases (5.1%) and without identifiable preceding signs in 9 cases (23%). The mean uterine and ovarian volume was significantly smaller in POF group than in the control group. Antral follicle count (AFC) was also significantly lower in POF group. Vaginal ultrasound detected at least one ovary in 89.7% and follicular activity in 79.5% of the POF patients. Evidence of ovulation was found in 12 patients, and spontaneous pregnancy occurred in 2 patients with a pregnancy rate of 5.1%.

CONCLUSIONPatients with menstrual disturbance, polymenorrhea and oligomenorrhea are at risk of developing POF, in which case regular detection of the mean uterine volume, ovarian volume and AFC by vaginal ultrasound may help in early POF detection. Close monitoring can be necessary in the course of hormone replacement therapy, and timely intervention with assisted reproductive techniques may increase the chance of pregnancy.

In order to investigate the effect of rapamycin on the proliferation of human acute myeloid leukemia (AML) cells, the sensitive cells HL-60 and multidrug-resistant HL-60/VCR cells were chosen as research objects. The proliferation of cells was detected by growth curve method. The flow cytometer was used to analyze cell cycle. The expression of P-glycoprotein (Pgp) was determined by Western blot. The results demonstrated that there was a significant difference of cell growth inhibition rate between control group and rapamycin group (p < 0.05). The cell growth inhibition rate was dose- and time- dependent (p < 0.05). Flow cytometry detection showed that the cell percentage of G(1) phase in rapamycin group was higher than that in group without rapamycin, and that of S phase was lower. The cell growth inhibition rate in 50 nmol/L and 100 nmol/L rapamycin plus daunorubicin (DNR) group was more than that in DNR alone group (p < 0.05), especially when DNR was added at 24 hours interval after RAP. The expression of Pgp of HL-60/VCR cells was inhibited by rapamycin. It is concluded that the rapamycin can inhibit the proliferation of sensitive HL-60 and multidrug resistant HL-60/VCR cells. It can also increase sensitivity of HL-60 and HL-60/VCR cells to DNR, which provides new strategy for the therapy of refractory AML.

OBJECTIVETo observe the effect of Schisandra chinensis lignans (SCL) on neuronal apoptosis and PI3K/AKT signaling pathway of rats in the cerebral ischemia injury model, and study its possible mechanism.

METHODRats were orally administered SCL high, middle and low dose groups (100, 50, 25 mg x kg(-1)) for 14 days. The cerebral ischemia injury model was established by using the suture-occluded method to rate the neurological functions. The cerebral infarction area was observed by TTC staining. The pathological changes in brain tissues were determined by HE staining. Bcl-2 and Bax expressions were detected by immunohistochemical assay. The protein expressions of p-AKT and AKT were assayed by Western blotting.

RESULTCompared with the model group, SCL high, middle and low dose groups showed reduction in the cerebral infarction area to varying degrees, improve the pathological changes in brain tissues, promote the expression of apoptin Bcl-2 and p-AKT, and inhibit the expression of apoptin Bax.

CONCLUSIONSCL shows a protective effect on rats with cerebral ischemia injury. Its mechanism may be related to the increase in p-AKT ability and antiischemic brain injury capacity and the inhibition of nerve cells.

OBJECTIVEThe expression of C/EBPalpha protein and mRNA during automatically activation process in primary cultures of HSCs were observed in order to explore its possible association with the proliferation and activation of HSCs.

METHODSImmunocytochemistry, Western blot and RT-PCR were used to evaluated the expression of C/EBPalpha protein and mRNA; as well as the expression of alpha-SMA, Desmin, MMP2, type I procollagen (alpha1). The eukaryotic vector harboring the full length cDNA of C/EBPalpha was transfected into activated HSC, then immunocytochemistry was applied to confirm the transfection and evaluate the effect of transfection on the proliferation of HSC by calculating the PCNA-positive cells. The morphological changes of HSC were observed by use of phase-contrast microscope.

RESULTSConstitutive expression of mRNA and protein of C/EBPalpha were detected in primarily cultured HSCs, and the protein was seen in both nuclei and cytoplasm with the latter being dominant. Their expression levels reached highest at day 2 of the culture, then decreased gradually when continually cultured to the day 4, 7, 10, on the other hand, the expression of alpha-SMA, MMP2 and ColI(alpha1) increased steadily. Transient transfection was verified by the fact that much more and stronger C/EBPalpha stain was observed in transfected HSCs than in void-vector transfected cells. In C/EBPalpha gene transfected HSCs, the number of PCNA-positive cells dramatically decreased compared with the void-vector transfected cells 24h after transfection. In addition, the C/EBPalpha gene transfected HSCs died 36 h after transfection, a few surviving cells became longer and thinner in morphology, however the void-vector transfected cells almost all remained alive.

CONCLUSIONSC/EBPalpha was likely involved in the HSCs activation, and over-expressed C/EBPalpha by transfection had inhibitory influence on the proliferation of cultured rat HSCs.

OBJECTIVETo evaluate the value of ascitic bacterial 16S rRNA gene determination in the rapid diagnosis of spontaneous bacterial peritonitis (SBP).

METHODS16S rRNA gene from bacterial DNA in ascites was determined by quantitative fluorescent polymerase chain reaction (PCR) in 76 patients with suspected SBP and 6 patients with non-infectious ascites. The results were compared with those obtained from bacterial culture.

RESULTSThe positive rate of SBP was 22.4% among patients detected with ascitic bacterial 16S rRNA gene determination-based quantitative fluorescent PCR, which was significantly higher than that (7.9%) in patients only received bacterial culture (P<0.05). In addition,in 6 patients with non-infectious ascites,both the 16S rRNA gene determination-based quantitative fluorescent PCR and bacterial culture showed negative results.

CONCLUSIONS16S rRNA gene determination-based quantitative fluorescent PCR can be an effective tool for the rapid diagnosis of SBP. It is more sensitive than the bacterial culture.

OBJECTIVETo evaluate the significance of determining ascitic bacterial 16S rRNA by quantitative PCR combined with microarray (PCR-microarray) in the diagnosis of spontaneous bacterial peritonitis (SBP).

METHODSAscitic bacterial 16SrRNA was determined by real time fluorescent quantitative PCR-microarray in 76 cases of suspected SBP and 6 cases of non-infectious ascites with chronic liver diseases. The results were compared with ascitic bacterial culture simultaneously.

RESULTSOf 76 ascitic samples, 17 were detected bacteria positive by PCR-microarray, including 8 Grams positive(G+) and 9 Grams negative(G-), which was higher than that by bacterial culture which had only 6 ascitic samples detected positive (all G-); the positive rates were 22.4% vs 7.9%, respectively (P < 0.01). The bacterial strains detected by both methods in 6 cases had a consistency with each other. No bacteria were detected in another 6 cases of non-infectious ascites with chronic liver diseases.

CONCLUSIONSDetermination of ascitic bacteria 16S rRNA by PCR-microarray has a higher specificity and sensitivity in the diagnosis of SBP as compared with the bacteria culture. Application of this novel method can not only accelerate SBP diagnosis but also stratify the different pathogens.
