In order to investigate the mutation of HBV polymerase gene reverse transcription conserved region (P region) in chronic hepatitis B (CHB) patients, 212 CHB patients who took antiretroviral treatment with nucleotide analogues were chosen. The drug resistance mutations of HBV P region and HBV genotype were detected by Pyrosequencing. Sequence analysis showed that the drug resistance sites of HBV P region located at sites 173; 180; 181; 184; 204; 236 and 250. The main site of HBV P region drug resistance was 204 and 180, accounting for 35.8% and 23.5%, respectively. There were significant differences in the mutation rate of site 180 among different age groups. There were also significant differences in the mutation rate of site 204 among younger than 30 age group, 41 to 50 age group and 51 to 60 age group. (P < 0.05, P < 0.01). The mutation rate of site 180 combined with site 204 was 66.6%. The mutation rate of site 181 combined with site 236 was 23.3%. The age of C genotype infected patients was significantly older than B genotype infected patients (P < 0.01). M204V/I mutation mostly existed in the form of joint L180M mutation, the mutation rate was age-related. The detection of HBV genotypes and drug resistance sites of HBV P region have important clinical implications for the treatment and prognosis of patients with CHB.

Objective To analyze the effects of image quality and radiation dose of the patients with no heart rate control on different acquisition window settings.Methods A total of 75 patients underwent CTCA scan,with a median age of 55 years.All patients had no heart rate control.HR≤65 beats per minute acquisition phase setting was from 65%to 75%,65 beats per minute80 beats per minute acquisition phase setting was from 35%to 45%.Evaluated patients radiation dose and subjective image quality of coronary artery.Results 75 patients with ED was (2.44±1.21)mSv,group A was (1.54±0.41)mSv, group B was (3.57±0.53)mSv,group C was (1.64±0.27)mSv,group A vs group B(P=0.000),group A vs group C(P=0.854),group B vs group C(P=0.000).A total of 1 043 coronary artery segments of 75 patients were evaluated,with an average of 13.9 segments showed by every case,(3.66±0.51)scale.Group A was (3.75±0.44)scale,group B was (3.60±0.54)scale,group C was (3.38±0.67) scale,group A vs group B(P=0.000),group A vs group C(P=0.004),group B vs group C(P=0.032).Conclusion The prospective ECG gated sequence scan could obtain the image quality and avoid unnecessary radiation dose by adapting to the different heart rate.

Invasive pulmonary aspergillosis is valued in intensive care unit (ICU) patients, but in ICU patients, the diagnosis standard of the European Organization for Research on the Treatment of Cancer/Mycosis Study Group (EORTC/MSG) could easily lead to misdiagnosis and missed diagnosis. It’s imaging manifestations are diverse: halo sign, nodules or micro nodules, nodular shadow, pulmonary consolidation, wedge-shaped consolidation, voids, air crescent sign, ground glass shadow, and so on, and with the relative characteristic features. The sensitivity and specificity of galactomannan detection in bronchoalveolar lavage fluid (BALF) are high for diagnosis of invasive pulmonary aspergillosis in ICU patients, but the significance of the cultivation of lower respiratory tract specimens is limited.

Objective To review the research progress of functional magnetic resonance imaging in Self -referential Processing (SRP) of patients with Depression based on the papers published from 2004 to 2014 at abroad and domestic,with an attempted to explore the neuromechanism of depression and to provide reference for treatment of depression.Methods Major online database including PubMed,EBSCO,Ovid,Medline,Clinicalkey,Wan Fang,CNKI,Cqvip,and CBM date bases were searched in Octobor 2014.The key words we used are depressionor depressive disorder,Self-referential Processing or rumination orautobiographical memory or Self-face recognition, Functional Magnetic Resonance Inaging(tMRI)and so on.Results 28 studies were adopted in this study,findings from the study showed:①rumination,autobiographical memory (AM) retrieval,and self-face recognition(SFR) are SRP paradigms,the cortical midline structures (CMS)and default mode network (DMN) were involved in the SRP of depression.②Both medication and cognitive behavioral therapy could reduce the abnormal activation of CMS and DMN in patients with depression.Conclusioins ①Both CMS and DMN may be the neuromechanism of SRP of depression.②Both CMS and DMN may be used as objective indicators to evaluate the treatment response in patients with depression.

Objective: To observe the clinical effects of comprehensive treatmenton cutaneous region for low back pain.
Methods: One hundred and twenty outpatients with low back pain who met the diagnostic criteria were randomly divided into a cutaneous region group or a medication group, 60 cases in each group. The cases in the cutaneous region group were treated by Nie-pinching up the skin of the lumbosacral region, cupping and acupuncture. Those in the medication group were treated by oral administration of Celecoxib capsule. The visual analogue scale (VAS) and Oswestry disability index (ODI) were used to assess the therapeutic effects.
Results: After treatment, the VAS scores of both groups were different from those before treatment, showing statistical significances (allP<0.01). The D-valuse of VAS scores of both groups were different from those before treatment, showing statistical significances (allP<0.01). The D-value of OID scores in the cutaneous region group was significantly different from that in the medication group(P<0.01). After treatment, the total effective rate was 91.7% in the cutaneous region group versus 76.7% in the medication group, there was a significant difference in comparing the clinical effect (P<0.01).
Conclusion: Both comprehensive treatment on the cutaneous region and Celecoxib capsule can obviously relieve low back pain. But comprehensive treatment on the cutaneous region is better than Celecoxib capsule in the therapeutic effects.

BACKGROUND: Drug therapy can improve the clinical symptoms and extend the gestational age through the maternal way to treat intrahepatic cholestasis of pregnancy (ICP), however, fetal hypoxia and meconium-stained amniotic fluid can not clearly improved. OBJECTIVE: To explore the effect of replacement of amniotic fluid that contains high concentrations of bile acids by artificial amniotic fluid through amniocentesis in the rat model of ICP. DESIGN, TIME AND SETTING: Random control animal experiments were completed in the Laboratory (first-degree laboratory) of Animal Experimental Center in Chongqing Medical University from March to September 2008. MATERIALS: Forty SD pregnant rats with 15 days of pregnancy were randomly divided into intracavitary injection of S-Adenosyl-L-methionine (SAMe) (IUS), intracavitary injection of sodium chloride (IUN), intravenous injection of SAMe (IVS) and blank control (IC) groups, with 10 rats in each group. METHODS: On day 15 of pregnancy, ICP rat models were induced by daily injection of estradiol benzoate. On day 17 of pregnancy, 1 mg SAMe and 0.3 mL sodium chloride were injected into amniotic cavity of in the IUS and IUN groups through amniocentasis. Meanwhile, 30 mg SAMe were injected though tail veins in IVS group. No treatment was performed in the IC group. MAIN OUTCOME MEASURES: The meconium-stained amniotic fluid rate and the still birth rate were calculated. Total bile acid (TBA) level in amniotic fluid was measured. In addition, the expression of hypoxia-inducible factor 1 ?(HIF-1?) mRNA in the placenta of rats were examined by immunohistochemistry and reverse transcription PCR at the days 20 of pregnancy. RESULTS: The meconium-stained amniotic fluid rate in the experimental group was lower than that of the IC group (P
