Objective To evaluate the effect of digital subtraction angiography and transcatheter embolization for gastrointestinal hemorrhage.Methods Twenty patients with gastrointestinal hemorrhage received celiac arteries,superior mesenteric arteries and inferior mesenteric arteries angiography. Superselective angiography were performed when the arteries were suspicious by clinic or angiogrraphy.Ten patients with definite diagnosis and manifestation of hemorrhagic arteries by angiography were embolized after superseleetive catheterization with gelfoam particles,gelfoam particles and coils,polyvinyl alcohol particles. Results The positive signs were observed in 13 cases.The DSA features including contrast medium accumulation in the gastrointestinal tract outside vascular,aneurysm,tumorous vascularization and staining, artery affect and local vasospasm.The bleedings were stopped immediately in 8 patients.No rebleeding and intestinal ischaemia or necrosis were observed in 30 days.One patient died in the second day after embolization from multiple organ failure.Rebleeding occurred 3 days after embolization in another patient, and was recovered after surgical operation.Conclusion DSA is more effective for the diagnosis of gastrointestinal vascular malformation and tumors complicating acute bleeding.Transcatheter embolization is effective and safe to control the hemorrhage.

In this paper, we focus on the characteristics of LUS in diagnosing childhood pulmonary disease. LUS is convenient, noninvasive, and free of radiation. It helps in the differentiation of lung diseases. Therefore, LUS has the potential to become a reference instrument for bedside dynamic respiratory monitoring. We hope that this review will help clinicians become acquainted with LUS and will accelerate the extensive application of LUS in children.

OBJECTIVETo evaluate the effects of policosanol on serum lipid and heme oxygenase-1 (HO-1) in patients with hyperlipidemia.

METHODSThis randomized, open study included 72 patients with hyperlipidemia. The patients were randomly assigned to treatment group (policosanol, 20 mg/d, n = 36) or placebo group (placebo, two tablets/d, n = 36). The levels of serum lipids, hypersensitive C-reactive protein (hs-CRP), HO-1 were assessed before and after 16 weeks treatment. Drug-induced adverse effects and events were recorded during the observation period. The serum HO-1 was measured by ELISA.

RESULTS(1) After 16 weeks, all parameters remained unchanged in the placebo group; the level of TC decreased from (7.01 ± 1.03) mmol/L to (5.66 ± 0.83) mmol/L (-19.4%, P < 0.01), the level of LDL-C decreased from (4.78 ± 0.72) mmol/L to (3.70 ± 0.69) mmol/L (-22.5%, P < 0.01) in the treatment group. TG and HDL-C levels remained unchanged (P > 0.05) while the level of HO-1 significantly decreased from (1.82 ± 1.08) µg/L to (1.45 ± 0.81) µg/L (P < 0.01) and the level of hs-CRP decreased from (3.40 ± 3.64) mg/L to (1.86 ± 2.02) mg/L (P < 0.01) in the treatment group. (2) Safety index was similar between placebo and treatment groups (P > 0.05) and there was no adverse events including allergic reaction, muscle pain in all subjects during the observation period.

CONCLUSIONThe short-term data obtained from this small hyperlipidemia patient cohort suggest that policosanol is a safe lipid-lowering and anti-inflammatory agent for hyperlipidemia patients.

OBJECTIVETo investigate the efficacy of endoscopic nasal cavity enlarging surgery for the alleviation of nasal obstruction.

METHODSOne hundred and eight patients with deviation of the nasal septum (DNS) and chronic hypertrophic rhinitis (CHR) were included in this study. Individualized operations were performed. DNS patients were treated by three line tension relaxing correction or nasal septum plasty. CHR patients were treated by inferior turbinate out fracture in combination with plasma radiofrequency ablation for reducing the volume of nasal soft tissue, sub-mucoperiosteal partial resection of the inferior turbinate or partial inferior turbinectomy.

RESULTSAll patients were followed for 3-12 months after surgery with an effective improvement in 97.2%. Symptoms of headache or complications of rhinitis sicca were not found.

CONCLUSIONSBeing careful to keep the physiological function of nasal mucosa, the integrity of the nasal septum, appropriate expansion of the nasal cavity volume, and restore ventilation with bilateral symmetry of the nasal cavity, satisfactory relief of nasal obstruction can be achieved.

Cytisine (CYT), a partial agonist of α4β2-nicotinic receptors, has been used for antidepressant efficacy in several tests. Nicotinic receptors have been shown to be closely associated with depression. However, little is known about the effects of CYT on the depression. In the present study, a mouse model of depression, the unpredictable chronic mild stress (UCMS), was used to evaluate the activities of CYT. UCMS caused significant depression-like behaviors, as shown by the decrease of total distances in open field test, and the prolonged duration of immobility in tail suspension test and forced swimming test. Treatment with CYT for two weeks notably relieved the depression-like behaviors in the UCMS mice. Next, proteins related to depressive disorder in the brain region of hippocampus and amygdala were analyzed to elucidate the underlying mechanisms of CYT. CYT significantly reversed the decreases of 5-HT1A, BDNF, and mTOR levels in the hippocampus and amygdala. These results imply that CYT may act as a potential anti-depressant in the animals under chronic stress.

BACKGROUND AND OBJECTIVEConcurrent chemoradiotherapy for cervical carcinoma develops rapidly and has become a common and standard therapy in recent years. Both the local control rate and survival rate of patients were increased and the risk of death fell by 30%-50%. This study aimed to explore the efficacy of concurrent chemoradiotherapy plus adjuvant chemotherapy on and the treatment compliance of the patients with advanced cervical squamous cell carcinoma.

METHODSA total of 156 patients with stage IIa-IIIb cervical squamous cell carcinoma were randomly divided into the concurrent chemoradiotherapy group (experimental group) and radiotherapy group (control group). Intracavity and external beam radiation therapy were administered. At point A, 40-48 Gy were given by 10-12 fractions; at point B, 46-50 Gy were given by 23-25 fractions. In the same time, experimental group was treated by cisplatin (DDP, 40 mg) on day 1, repeated every week. Ten days after radiation therapy, TP regimen was administered as adjuvant chemotherapy.

RESULTSFor the experimental and control groups, the objective response rates were 88.61% and 75.32%, 1-year survival rates were 88.57% and 70.77%, 1-year local control rates were 81.43% and 64.62%, 3-year survival rates were 82.14% and 57.69%, and 3-year local control rates were 75.00% and 46.15%, with significant differences (P<0.05). Quality of life of all patients were significantly improved after treatment (P<0.05).

CONCLUSIONConcurrent chemoradiotherapy plus adjuvant chemotherapy for advanced cervical cancer can improve short-term and long-term survival and local control rates of patients, improve the quality of life, and the toxicity can be tolerated.

As an extension of proteomics, peptidomics has been widely used in medical and biological researches. However, the effect of reproducibility of identification method on peptidomics is not yet clear. In this work, the urine sample of a healthy people was analyzed for seven times in parallel by nano-liquid chromatography-high-resolution tandem mass spectrometry. To illustrate the variability and stability among these experiments, the number of spectra, the utilization of total spectra, the number of identified peptides, the number of proteins, and the ionic strength and retention time of peptides were counted and compared. The average number of peptides was 208 and the standard deviation was 38. 7. After all of data were combined, 426 peptides belonging to 114 proteins were obtained, while only 109 peptides coming from 35 proteins were identified in each experiment, indicating that there were both an randomness and a relative stability for LC-MS analysis. Increasing the number of parallel experiments would expand the data set of peptidomics, but the rate of increase would decrease over 3 or more measurements. Compared with peptides, the results of peptidomics were more stable at protein level, indicating that proteins were more robustly peptidomics biomarker than the peptides.

Objective To investigate the distribution and antimicrobial resistance of Pseudomonas aeruginosa (P.aeruginosa) from intensive care units(ICUs) and general wards of a hospital,and provide scientific basis for rational use of antimicrobial agents in clinic.Methods Identification and antimicrobial susceptibility testing of clinically isolated bacteria in this hospital in 2016 were performed by VITEK 2 Compact automatic microbial analysis system,difference in antimicrobial resistance of P.aeruginosa between ICUs and general wards was compared.Results The tested specimens were mainly sputum in both ICUs and general wards,accounting for 78.7％ and 66.5％ respectively.There was no significant difference in the isolation rate of P.aeruginosa between ICUs and general wards (11.7％ vs 11.0％,P＞0.05).P.aeruginosa isolated from ICUs had the highest resistance rate to aztreonam (73.8％),resistance rates to piperacillin/tazobactam,cefoperazone/sulbactam,ceftazidime,imipenem,and meropenem were all up to more than 50％;P.aeruginosa detected in general wards had the highest resistance rate to aztreonam(59.6 ％),followed by piperacillin/tazobactam and imipenem,accounting for 48.0 ％ and 44.3 ％ respectively;resistance rates of P.aeruginosa isolated from ICUs to 12 kinds of antimicrobial agents were all higher thanthose of general wards(P＜0.05).Conclusion Resistance rate of P.aeruginosa from ICUs is higher than that in general wards,which should be paid attention,antimicrobial agents should be selected for clinical treatment of infection according to the results of antimicrobial susceptibility testing result.
