Objective To investigate the short and long term effects of Sunmax injection for the rhytidoplasty on different parts of the fa-cial wrinkles. Methods 1 028 face lift patients were collected from January 2007 to December 2011 who admitted to our plastic surgery de-partment,236 cases of male,792 cases of female,with an average age of 48. 7 (21~72)years old. According to different drug injection sites, all the patients were divided into 5 groups:wrinkles between eyebrows,the forehead wrinkles,nasolabial fold wrinkles, crow's feet,nose wrin-kles. The rhytidoplasty effects of 5 groups a day,1 month,3 months,6 months,9 months after injection were observed and compared. Further-more,the short and long term effects of the Sunmax injections were integrated to analyze. Results After Sunmax injection,a variety of skin wrinkles and sags disappeared;1 month after injection,wrinkles did not appear;3~6 months after injection,the effects was still as the same as the day after injection. 9 months after injection,the effects for the forehead wrinkles and crow's feet was slightly diminished. Conclusion Sunmax injection is an emerging technology to remove facial wrinkles,which has been widelymused inmour department for severalmyears and got patients' postoperative satisfaction. It is worth spreading for rhytidoplasty.

Tobacco mosaic virus (TMV) causes significant yield loss in susceptible crops irrigated with contaminated water. However, detection of TMV in water is difficult owing to extremely low concentrations of the virus. Here, we developed a simple method for the detection and quantiifcation of TMV in irrigation water. TMV was reliably detected at concentrations as low as 10 viral copies/μL with real-time PCR. The sensitivity of detection was further improved using polyethylene glycol 6000 (PEG6000, MW 6000) to concentrate TMV from water samples. Among the 28 samples from Shaanxi Province examined with our method, 17 were tested positive after virus concentration. Infectivity of TMV in the original water sample as well as after concentration was conifrmed using PCR. The limiting concentration of TMV in water to re-infect plants was determined as 102 viral copies/mL. The method developed in this study offers a novel approach to detect TMV in irrigation water, and may provide an effective tool to control crop infection.

OBJECTIVETo analyze the status of acute upper respiratory infection and influenza-like illness (ILI) among community residents in Jinan in 2015, and to make a understand of the patient's medical treatment behavior and influenza vaccination coverage status in 2014.
METHODSBalloting method and convenient sampling method were used to launch a household survey. The residents who had been in Jinan for more than 3 months were selected, to investigate the residents' attack ratio of acute upper respiratory and influenza-like from Jan. 8 to Feb. 7, 2015. Totally, 1 300 persons from 410 families were involved in this survey which recovered 1 241 valid questionnaires with the efficiency of 95.5%. Based on the national age-urban demographic statistics in 2010, the attack rates of acute respiratory infections, influenza-like illness were estimated by the direct standardization method, and the influenza vaccination rates were also calculated in this study. χ(2)-test method was used to compare the different status of incidence and vaccination among residents with different features.
RESULTSThe attack rate of acute upper respiratory infection and influenza-like illness in Jinan from January 8, 2015 to February 7, 2015 were 30.2% (375 cases), and 6.1% (76 cases), respectively, with a standardized rate of 29.1% and 5.4%. 5.3% (66 cases) of the residents have vaccinated with the influenza vaccine inoculation, with an adjusted rate of 3.8%. The attack rate difference of acute upper respiratory tract infections was statistically significant between each age group (χ(2)=17.121, P= 0.002). The 0-4 age group had a highest attack rate (45.4%) of acute respiratory infection, while the 15-24 age group got the lowest (26.5%). 38.9% (146 cases) of patients went for a treatment in hospital. Among them, 37.7% (55 cases) of them selected the county level hospitals for treatment, 37.7% (55 cases) selected the community level hospitals, and 24.6% (36 cases) selected the individual clinic. Significant differences of influenza-like illness attack rate between each age group were also found in this study (χ(2)=76.79, P<0.001). 0-4 age group had the highest attack rate (22.7%). 81.6% (62 cases) of the ILI sought treatment in the hospital, of which 53.2% (33 cases) selected county level hospital or above, and 33.9% (21 cases) selected community hospital, and 12.9% (8 cases) selected the individual clinic.
CONCLUSIONThe attack rate of acute upper respiratory infections among the residents of Jinan was high, whereas that of influenza-like illness was relatively low. 0-4 age group had a higher risk of ILI than other age groups. Most of the cases were likely to take the treatment in large hospitals. In general, the coverage rate of influenza vaccination was relatively low.

Objective:
To understand the viral spectrum of influenza-like illness (ILI), Shandong province during 2013-2014.
Methods:
The data of 36 ILI outbreaks were collected and analyzed. Multiple respiratory pathogens were detected with RT-PCR in pharynx swab specimens.
Results:
Totally, 35 outbreaks occurred in winter and spring, and dispersed in 12 cities; 27 outbreaks happened in primary and secondary schools. Many of the outbreaks, 17 (47.2%), were caused by influenza virus type B (FluB), followed by FluA H1 and H3, 5 (13.8%) outbreaks, respectively. Mixed infection caused 7 outbreaks. Totally 437 samples were collected, with 235 (53.8%) positive specimens, in which FluB was mostly detected, 142 (32.5%). Except Flu, parainfluenza virus type 2 (PIV2) was the most frequently detected, followed by coronavirus (CoV). The constituent ratio of FluB under 15 years of age was the highest, such as CoV in 25-59 years old group and FluA H1 in others groups.
Conclusions
ILI outbreaks occurred mostly in primary and secondary schools. Virus was the main pathogen, with the dominant strains of FluB. However, the dominant strain in different age groups was different.
