RESUMO
This article uses the "behavioural and social drivers of vaccination" model released by the World Health Organization (WHO) in 2022 to analyze influenza vaccine policy documents issued by the state and governments. This indicates that the current influenza vaccination policy in China has paid some attention to "publicity and mobilization", but it still pays insufficient attention to "vaccination convenience". It is recommended to continue to strengthen publicity and mobilization, explore ways to improve the convenience of vaccination, formulate corresponding plans to improve the convenience of vaccination, scientifically set vaccination rate targets, and encourage areas with conditions to carry out free vaccination projects for key populations.

RESUMO
<p><b>OBJECTIVE</b>To study the effects of intrahippocampal injection of cellular prion protein (PrP) antibody on cognitive deficits of APPswe/PSEN1 transgenic mice.</p><p><b>METHODS</b>Eight-month-old male APPswe/PSEN1 transgenic mice were subjected to bilateral intrahippocampal injection of a single dose (2 µL) of anti-PrP monoclonal antibody (EP1802Y) or PBS, with wild-type C57Bl/6J mice serving as the control group. After two months, the mice were tested for cognitive behaviors using open filed (OF) test, Morris water maze (MWM) test, fear conditioning (FC) test, and novel object recognition (NOR) test, and immunohistochemistry was used to examine the changes in hippocampal expression of Aβ.</p><p><b>RESULTS</b>The EP1802Y-treated and PBS-treated mice showed no significantly differences in the performance in OF test in terms of central activity time or total distance of activity (P>0.05), nor in NOR test in terms of novel object recognition index (P>0.05). In MWM test, the EP1802Y-treated and PBS-treated mice showed significantly reduced crossings of the hidden platform as compared with the wild-type mice (P<0.05), but EP1802Y-treated mice had a significantly shorter swimming distance to find the platform than PBS-treated mice (P<0.05). No significant differences were found in the results of FC test among the 3 groups. Immunohistochemistry revealed a significantly reduced expression of Aβ in the hippocampus of EP1802Y-treated mice.</p><p><b>CONCLUSION</b>Intrahippocampal injection of PrP antibody can improve cognitive deficits of APPswe/PSEN1 transgenic mice, which sheds light on a novel therapeutic approach for Alzheimer's disease that targets PrP to lower the toxicity of Aβ oligomer.</p>
RESUMO

RESUMO
<p><b>BACKGROUND</b>Urolithiasis in pediatric population is a serious problem with the incidence increased these years. In the management of larger stones (diameters >2 cm), percutaneous nephrolithotomy (PCNL) is considered to be the gold standard. This study aimed to investigate the efficacy and safety of mini-PCNL under total ultrasonography in patients aged <3 years.</p><p><b>METHODS</b>We reviewed 68 patients (80 renal units) aged <3 years between August 2006 and December 2014 in Peking University People's Hospital and Beijing Tsinghua Changung Hospital, including 36 renal units with a single stone, 6 with staghorn stones, 14 with upper ureteral stones, and 24 with multiple stones. The mean age of the patients was 24.2 months (range 6-36 months), and the mean maximum stone diameter was 19.2 mm (range 10-35 mm). The puncture site selection and tract dilation were guided by Doppler ultrasonography solely. All procedures were performed using 12-16 Fr tracts. Stones were fragmented using pneumatic lithotripsy and a holmium laser with an 8/9.8 Fr rigid ureteroscope.</p><p><b>RESULTS</b>Fifty-six patients with unilateral stones underwent a single session procedure, and 12 patients with bilateral stones underwent two procedures. The mean time to establish access was 2.8 min (range 1.8-5.0 min), the mean operative time was 36.5 min (range 20-88 min), the mean decrease in hemoglobin concentration was 8.9 g/L (2-15 g/L), and the stone-free rate (SFR) at hospital discharge was 94.0%. The mean postoperative hospital stay was 7.1 days (range 3-13 days). Postprocedure complications included fever (>38.5°C) in five patients and reactive pleural effusion in one patient. Blood loss requiring transfusion, sepsis, adjacent organ injury, and kidney loss were not observed.</p><p><b>CONCLUSIONS</b>This study indicated that ultrasound-guided mini-PCNL is feasible and safe in patients aged <3 years, without major complications or radiation exposure.</p>

<p><b>OBJECTIVES</b>To analyze the pathogenic bacterial's distribution and the drug resistance in the upper urinary tract stones, and to provide the information for choosing suitable antibiotics.</p><p><b>METHODS</b>Stone samples were taken for culture and for drug sensitivity test in 146 patients undergoing percutaneous nephrolithotomy between April 2007 and October 2008, and the results were analyzed.</p><p><b>RESULTS</b>Pathogens presented in 72 (49.3%) patients. There were 70 (86.4%) Gram-negative bacteria strains. Escherichia coli, Pseudomonas aeruginosa and Enterobacter cloacae were the predominant bacteria, accounted for 30.9%(25 strains), 23.5% (19 strains) and 12.3% (10 strains), respectively. There were 10 (12.3%) Gram-positive bacteria strains, the predominant bacteria was Staphylococcus epidermidis (6 strains), accounting for 7.4%. And there was 1 fungi strain (1.2%). Resistance to ampicillin/sulbactam (88.7%), ceftriaxone (81.3%) and ciprofloxacin (67.5%) was most commonly found in pathogen, and the rate of resistance to amikacin, imipenem and piperacillin/tazobactam were 8.6%, 10.0%, 10.0%, respectively. Erythromycylamine, teicoplanin, SMZ-TMP, nitrofurantoin were sensitive to Gram-positive bacteria.</p><p><b>CONCLUSIONS</b>Bacterial's distribution of upper urinary tract stones are multiple, and the majority pathogen is Gram-negative bacteria. A big variant resistance is found among different bacterium. The suitable antibiotics should be chosen according to the different bacterium in the patients who underwent percutaneous nephrolithotomy.</p>

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of management of renal stone in non-dilated collecting system by percutaneous nephrolithotripsy (PCNL) under ultrasound guidance.</p><p><b>METHOD</b>From September 2003 to April 2005, 132 cases of renal stone in non-dilated collecting system were performed by percutaneous nephrolithotripsy. A stent was first inserted into the pelvis through cystoscope, and saline was instilled to dilate collecting system. Antegrade percutaneous access was obtained by B-type ultrasound guidance. A combination pneumatic and ultrasonic lithotrite were used to disintegrate and remove stone under direct vision. Clinical data including operation time, complications and stone free rate were analyzed retrospectively.</p><p><b>RESULTS</b>The percutaneous renal access was successfully established under B-type ultrasound guidance in all patients, immediate phase I lithotripsy was performed in 129 cases and delayed phase II lithotripsy in 3 cases. Operation time ranged from 70 to 130 minutes, average time was (89 +/- 11) minutes, 3 cases were supported by blood transfusion, severe complications did not occur during nephrolithotripsy. Stones were cleared in 114 out of 132 cases (86.4%) during immediate phase I lithotripsy, residual stone fragment was found in 18 cases who received second PCNL or adjuvant extracorporeal shock wave lithotripsy.</p><p><b>CONCLUSION</b>The management of renal stone in non-dilated collecting system using PCNL appears to be efficacious and safe under B-type ultrasound guidance.</p>
