Objective:To analyze the detection of gallbladder polyps among shift nurses in Shengjing Hospital of China Medical University in physical examination and its related influencing factors, so as to provide scientific basis for shift nurses to prevent gallbladder polyps.Methods:A total of 1 119 shift nurses who had physical examination in Shengjing Hospital of China Medical University from January 1 to March 31, 2018 were selected. The patients with gallbladder polyps diagnosed by ultrasound were included in the case group, and those without gallbladder polyps were taken as the control group. Age, gender, body mass index (BMI), night shift frequency, education level, Department, meal regularity, drinking history, smoking history, serum triglyceride, serum total cholesterol, hepatitis B surface antigen, serum alanine aminotransferase and serum aspartate aminotransferase levels were compared between the two groups.Results:Univariate analysis showed that age ( P<0.001), gender ( P=0.028), BMI ( P=0.005), night shift frequency ( P=0.021) were the factors with statistically significant difference between the case group and the control group. There were no statistically significant differences between the case group and the control group in terms of education level, department, dining regularity, drinking history, smoking history, hepatitis B surface antigen, serum triacylglycerol, serum total cholesterol, serum alanine aminotransferase, serum aspartate aminotransferase levels ( P>0.05). Logistic regression analysis showed that age, BMI and night shift frequency were the influencing factors in the regression equation ( P<0.05). Conclusion:Age, BMI and night shift frequency may be related risk factors of gallbladder polyps in shift nurses.

Objective To determine the effect of high-intensity physical activity on bone mineral density(BMD). Methods Thirty-six female soccer players (19.56±1.46 years) with more than two years training history and at least ten months soccer training annually were recruited as experiment group. Thirty-three female sedentary college students, whose physical activities were limited to the compulsory physical education curriculum,were assigned to the control group. BMD of lumbar spine and femoral neck were obtained before and after 24 months research,using dual energy X-ray absorptiometry. Results After 24 months research, increased BMD were found in both groups. Soccer players had 2.25% increase of lumbar spine BMD(P<0.05) and 4.90% increase of femoral neck BMD(P<0.05). Sedentary college students had 0.89% increase of lumbar spine BMD(P>0.05) and 2.03% increase of femoral neck BMD(P>0.05). Compared with sedentary college students,Lumbar spine and femoral neck BMD in soccer players were significantly higher(P<0.05) after 24 months research. Conclusion Long-term soccer training had the effect of greater acquisition of BMD.

OBJECTIVE: To develop a method for simultaneous determination of gentiopicroside, prim-O-glucosylcimifugin, calycosin-7-O-β-D-glucoside, paeonol, magnolin, imperatorin and isoimperatorin in Fangzhi nasopharyngeal granules by HPLC.

Objective • To investigate the clinical and genetic characteristics of nevoid basal cell carcinoma syndrome (NBCCS) combined with epilepsy. Methods • The clinical data of a proband with the symptom of epileptic seizures in Department of Neurology, Tongren Hospital, Shanghai Jiao Tong University School of Medicine was retrospectively analyzed. Facial nevoid was resected and hematoxylin-eosin (H-E) staining was examined. Wholeexome sequencing was performed on the blood DNA of the proband and his family members. Sanger sequencing was used for co-segregation analysis. Results • The proband was highly suspected of having NBCCS according to the clinical diagnostic criteria of NBCCS. H-E staining showed typical pathological features of basal cell carcinoma. Heterozygous deletion at c.3364_3365del base in the exon 20 of patched 1 (PTCH1) gene was found in this family. Conclusion • The heterozygous deletion in the exon 20 of PTCH1 gene (c.3364_3365del) may be a potential hot spot mutation for NBCCS, especially in patients combined with neurological manifestations, such as epilepsy.

OBJECTIVETo investigate the effects of granulocyte colony-stimulating factor (G-CSF) on peripheral endothelial progenitor cells (EPC) and atherosclerosis (AS) in cholesterol-fed rabbits.

METHODSMale New Zealand white rabbits were randomly divided into control group, G group (Recombinant Human Granulocyte Colony Stimulating Factor Injection rhG-CSF 50 microg/d), AS group (high cholesterol diet) and G + AS group (rhG-CSF 50 microg/d plus high cholesterol diet, n = 8 per group). Peripheral blood was collected at baseline and at 1, 4, 8 and 12 weeks, total mononuclear cells (MNCs) were isolated from peripheral blood by Ficoll density gradient centrifugation, and then the cells were plated on fibronectin-coated culture dishes. After being cultured for 7 days, EPCs were characterized as adherent cells double positive for DiLDL uptake and lectin binding by direct fluorescent staining under a laser scanning confocal microscope. After being cultured for 3 days, the number of EPC (PE-CD34/FITC-CD133 double-stained positive cells) was quantified by flow cytometric analysis. Serum NO was measured and aortic plaque area analyzed at 12 weeks.

RESULTSEPC number was low in control and AS groups and EPC number was significantly increased ( approximately 13-fold, P < 0.001) compared to baseline at 1 week in G and G + AS groups and remained at this level throughout the study period in G group while decreased gradually in G + AS group and returned to baseline level at 12 weeks. Aortic atherosclerotic plaque was visible in both AS and G + AS groups, however, the aortic atherosclerotic plaque area was smaller in G + AS group than that of in As group (59.8 mm(2) +/- 26.9 mm(2) vs. 251.5 mm(2) +/- 83.4 mm(2), P < 0.01). Serum NO was similar between AS and G + AS groups and significantly higher than that in control and G groups.

CONCLUSIONCSF could attenuate atherosclerosis in cholesterol-fed rabbits by increasing circulating EPC.

OBJECTIVETo evaluate the time course of granulocyte-colony-stimulating-factor (G-CSF), estrogen and various doses of atorvastatin on endothelial progenitor cells (EPCs) mobilization.

METHODA total of 48 male New Zealand White rabbits were treated with placebo, estrogen (0.25 mg.k(-1).d(-1)), Atorvastatin (2.5, 5, or 10 mg) and G-CSF (50 microg/rabbit/d), respectively. Peripheral EPCs number was surveyed weekly for 4 weeks by FACS analysis (double-positive for PE-CD34/FITC-CD133) and under fluorescent microscope (double-positive for FITC-UEA-1/Dil-acLDL). Serum nitric oxide (NO) and lipids were also measured at the third week.

RESULTSPeripheral EPCs was significantly increased in G-CSF treated animals and remained constant for 4 weeks compared to placebo treated animals. Atorvastatin increased peripheral EPCs dose-dependently from 2.5 to 5 mg and peaked at the third week while peripheral EPCs number was not affected by 10 mg.k(-1).d(-1) atorvastatin during the first 3 weeks and was significantly higher only in the fourth week compared to placebo group. Estrogen also significantly increased peripheral EPCs at the third and fourth week compared to placebo group. At the third week, serum NO was similar in G-CSF group, significantly higher in atorvastatin 5 mg.k(-1).d(-1) and estrogen groups while significantly lower in atorvastatin 10 mg.k(-1).d(-1) group compared to placebo group. Serum lipids were similar among various groups.

CONCLUSIONAtorvastatin, estrogen and G-CSF could mobilize EPCs. The mobilization efficacy is as follows: G-CSF > atorvastatin 5 mg.k(-1).d(-1) > estrogen > atorvastatin 2.5 mg.k(-1).d(-1) > atorvastatin 10 mg.k(-1).d(-1). NO might partly contribute to the mobilizing effect of estrogen and atorvastatin.

OBJECTIVETo investigate the incidence and clinical features of mixed infections in children with Mycoplasma pneumoniae (MP) pneumonia.

METHODA total of 201 cases diagnosed as MP pneumonia were investigated for mixed infections by sputum bacterial culture, respiratory virus antigen detection and serum Chlamydia pneumoniae antibody test. For those with the indications for bronchoscopy, we also did bronchoalveolar lavage and lavage bacterial culture.

RESULTA high incidence (103/201, 51.2%) of mixed infections in children with MP pneumonia was revealed. The most frequent co-infected pathogen was Chlamydia pneumoniae (52, 25.9%), followed by viruses (29, 14.4%), and bacteria (22, 10.9%). Among viruses, respiratory syncytial virus was the most common (17, 8.5%), followed by adenovirus (6, 3.0%), parainfluenza virus type III (4, 2.0%) and influenza virus type B (2, 1.0%). Sputum bacterial culture was positive in 14/201 (7.0%) cases, Streptococcus pneumonia being most common (6, 3.0%). BALF culture yielded positive results in 11.6% (8/69), Streptococcus pneumonia was also common (5, 7.3%). Among 29 cases with MP and virus coinfection, 26 were younger than 3 years (89.7%), while for MP and Chlamydia pneumoniae coinfection, most of them were older than 3 years (40/52, 76.9%). Compared with non-mixed infections, those with mixed infections had longer fever duration (24.5% and 40.8% longer than 10 d), more frequently developed pleural effusion (11.2%, 23.3%) and large area of shadow in chest imaging (35.7%, 51.5%). White blood cell [(14.28 ± 4.99) × 10(9)/L], C-reactive protein (CRP) [69(32.5 - 99.5) mg/L] and neutrophil ratio in BALF [0.86 (0.63 - 0.91)] were much higher in children with mixed bacterial infections than that in non-mixed infections [(9.06 ± 3.47) × 10(9)/L, 3 (0 - 31.0) mg/L, 0.44 (0.03 - 0.88)]. But no significant difference was found in peripheral blood neutrophil proportion between mixed bacterial infections (0.38 ± 0.25) and non-mixed infections (0.51 ± 0.19).

CONCLUSIONMore than half of cases with MP pneumonia had mixed infections, most commonly caused by Chlamydia pneumonia followed by viruses. The incidence of mixed infections with bacteria was low. Mixed infections with virus were more common in young children, while mixed infection with Chlamydia pneumoniae was more common in older ones. Bacterial infections should be paid more attention, especially those caused by Streptococcus pneumoniae, for those with high peripheral white blood cell counts, high CRP levels and high proportion of neutrophils in BALF.

OBJECTIVETo investigate the biocompatibility of new bone tissue engineering scaffolds, A:D, L-polylactic acid (PDLLA)/polylactic acid-polyethylene glycol-polylactic acid-polylactic acid (PLA-PEG-PLA)/Tricalcium phosphate and B: PDLLA/PLA-PEG-PLA in vivo, compared with PDLLA in repair of a rabbit mandibular body defect.

METHODS24 New Zealand adult rabbits were divided into 4 groups randomly. 15 mm x 6 mm defects were made surgically in the bilateral mandibular bodies and each hemi-mandible was assigned as an experimental unit. The defects were randomly repaired with scaffold materials in each group. Specimens obtained were evaluated with general observation, X-ray, histomorphology and computerized graphical analysis at 2, 4 , 8, 12 weeks after surgery.

RESULTSCompared with PDLLA, the new scaffold materials B showed biocompatibility. At the same time the quantity of new bone produced was much more than that in control group (P<0.05). The new scaffold materials A showed the clear chronic granulomatous inflammation.

CONCLUSIONNew scaffold material B had sound biocompatibility. It was much better than PDLLA. So it may be an ideal bone tissue engineering scaffold material. A is not adapted to be used as scaffold material.

OBJECTIVETo study the effects of angiotensin II receptor blockers (ARB), losartan and irbesartan, on blood pressure and serum uric acid (SUA) level in mild to moderate essential hypertensive patients complicating hyperuricaemia.

METHODSA total of 351 eligible patients were recruited in this multi-center, randomized, double-blind parallel clinical trial. After 1 week screening and a 2 week single-blinded placebo wash-out period, patients were randomly assigned to receive losartan 50 mg (n=76) or irbesartan 150 mg (n=175) once daily for 4 weeks, followed by a double-dose for another 4 weeks in patients whose seated DBP were >or=90 mm Hg or SBP>or=140 mm Hg at the end of 4 weeks. The SUA concentration and blood pressure were measured at baseline, 4 and 8 weeks post therapy.

RESULTSThree hundred and twenty-five patients completed the study (162 in the losartan group and 163 in the irbesartan group). Both groups were well matched for baseline clinical characteristics and demographics. SUA was significant reduced in losartan group (430.93 micromol/L vs 372.35 micromol/L, P<0.0001), but not in Irbesartan group (430.46 micromol/L vs 420.67 micromol/L, P>0.05) 8 weeks post therapy compared to baseline level. Blood pressure was significantly and equally reduced in both groups after 8 weeks treatment compared to baseline level (P<0.0001).

CONCLUSIONLosartan is an optimum choice of medication for patients with mild-to-moderate hypertension complicating hyperuricemia.
