Objective To analyze the pathogenic epidemiological characteristics of acute lower respiratory tract infection(ALRTI) in children in Gansu Province from 2012 to 2015. Methods The surveillance data of 458 children infected with ALRTI in 10 sentinel hospitals in Gansu province from 2012 to 2015 were collected, and infection status and epidemiological characteristics of each virus and bacteria were analyzed by descriptive study methods. Results The male to female ratio of the 458 children with ALRTI was 1.81:1, and the positive detection rate of the virus was 33.62%（95% CI：29.28%-37.97%), among which the positive detection rate of respiratory syncytial virus was the highest (12.23%).The positive detection rate of bacteria was 24.84%（95% CI：20.04%-29.65%),among which the positive detection rate of streptococcus pneumoniae was the highest (18.47%).There was significant no difference in the positive detection rate of virus and bacteria between children of different genders (P>0.05).There was significant no difference in the positive detection rate of virus among children of different age groups ( 2=5.980,P=0.050), but the positive detection rate of bacteria was different ( 2=12.078,P=0.002).Positive detection rates of virus infection and bacterial infection were different in distinct seasons (all P<0.05). By using logistics regression analysis, season, age and sentinel hospital were the influencing factors of ALRTI virus infection in children (all P<0.05), and sentinel hospital and years were the influencing factors of ALRTI bacterial infection in children (all P<0.05). Conclusion Respiratory syncytial virus, influenza virus and parainfluenza were the main causes of ALRTI virus infection in children aged 0-14 years in Gansu province, and the main bacterial infections were streptococcus pneumoniae and haemophilus influenzae, the number of virus infection was more than that of bacterial infection. Viral and bacterial infection had the same peak incidence.

Objective To understand the main serotypes, antibiotic resistance profiles and molecular typing characteristics of Listeria monocytogenes（LM) isolated from foods in Shandong Province from 2013 to 2016. Methods The antibiotic sensitivity of LM was tested by broth microdilution method. The serotypes were determined by slide agglutination and PCR, and the molecular typing was carried out by pulsed field gel electrophoresis (PFGE) and multilocus sequence typing(MLST) . Results Most of 191 LM strains were sensitive to the eight antibiotics tested. Tetracycline resistance was most prevalent (15/191, 7.85%). There was no significant difference in the 8 antibiotic resistance monitored for 4 years (P=1.000). The serotype 1/2a, 1/2b and 1/2c accounted for 38.82% (66/170), 18.82% (32/170), and 42.36% (72/170), respectively. The patterns of SDSRZXDZ016, S2014L031 and SDSRZX030, totally accounted for 33.78%, were the dominant types. The main ST types were ST9, ST8 and ST121, which accounted for 81.18% (69/85). The clinical common types, ST3, ST7 and ST87 accounted for 8.23% (7/85), mainwhile new ST type was not found. Conclusion The LM strains isolated in Shandong Province from 2013 to 2016 were sensitive to most antibiotics, but some strains were resistant to tetracycline and erythromycin. The dominant serotypes were 1/2c and 1/2a. Serotype 4b, prone to outbreaks of listeriosis, was not found. The main PFGE types were SDSRZXDZ016, S2014L031 and SDSRZX030, which were continuously found from 2013 to 2016. The main ST types were ST8, ST9 and ST121. The clinical types, ST3, ST7 and ST87 were isolated from food and should be paid seriously attention to.

One hundred and nine consecutive coronary heart disease (CHD) patients with obstructive sleep apnea (OSA) undergoing percutaneous coronary intervention (PCI) during February 2016 to August 2018 were enrolled in the study. After treatment the quality of sleep was improved in 35 cases (observation group) and was not improved in 74 patients (control group). The basic characteristics, coronary lesions of patients were compared between two groups. Compared with the control group, patients in observation group had significant higher proportion of males [80.0%(28/35) vs. 59.5%(44/74), χ²=4.471, P=0.035], smoking history [85.7% (30/35) vs. 63.5% (47/74), χ²=5.647, P=0.018], lower body mass index [(25.8±3.1) kg/m² vs. (27.4±3.2) kg/m², t=2.461, P=0.033]. Compared with control group, the observation group had lower coronary Gensini score[(35.4±5.7) vs. (38.7±6.5), t=2.571, P=0.011], less number of stent[ (1.4±0.4) vs. (1.6±0.4), t=2.427, P=0.016]. And the lesions were mostly distributed in the right coronary artery in observation group (61.9%, 26/35) (χ²=11.759, P=0.003).Conclusion The improvement of sleep quality by PCI depends on the clinical features and coronary artery lesions of CHD patients with OSA.

Professor Shao Jing-ming had practiced Chinese medicine for more than 80 years with rich clinical experience and exquisite acupuncture techniques. From his clinical experience, Professor Shao's clinical features can be summarized as the followings: attaching importance to the theory of meridians and collaterals, combining pattern identification and disease identification, using fewer acupoints for treatment, and using Ashi point and Hegu (LI 4) to treat goiter. He emphasized the priority and sequence in acupoint-selection and manipulation. In treatment of epilepsy, he proposed to treat it according to the situation and paid great attention to the special function of the extraordinary acupoints. During the onset, it should be managed by calming the mind and controlling the symptoms; during the remission period, acupuncture and drugs should be applied simultaneously to regulate qi-blood and yin-yang, so as to reduce the frequency of attacks. He believed that acupuncture manipulation be one of the key factors in achieving the efficacy. In treatment of the motive diseases, such as convulsions and cramps, acupuncture with static and longer needle-retaining time should be adopted to control the limb movement, to strengthen the stimulation and to obtain a long-term efficacy. Professor Shao Jing-ming's medical records range from internal medicine, external medicine, gynecology and pediatrics, listing various refractory diseases effectively treated by him. Professor Shao was a moral and erudite Chinese medicine master, and his clinical experience is worthy of inheritance and development.

Objective To analyze the prognostic impact of Ikaros family zinc finger 1(IKZF1)mutation on adult Philadelphia chromosome (Ph1) positive acute lymphoblastic leukemia (ALL) patients.Methods IKZF1 mutation was detected in 63 adult Phi positive ALL patients at diagnosis using capillary electrophoresis.Recruited patients were treated in our center and other three hospitals in Ningbo from January 2014 to January 2017.Clinical data were collected and retrospectively analyzed.Results Thirty-nine (61.9％) patients were positive IKZF1 mutation in this cohort.The white blood cell (WBC) count in IKZF1 mutation group was significantly higher than that of mutation negative group [(64.6±11.3)× 109/L vs.(33.7±5.6)×109/L,P＜0.05].Patients with WBC count over 30×109/L accounted for 56.4％ in IKZF1 mutation group.Complete remission (CR) rate in the IKZF1 mutation group was also lower than that of negative group after induction chemotherapy (64.1％ vs.75.0％,P＞0.05).IKZF1 was a negative prognostic factor but not independent factor for survival by univariate and multivariate analyses.Patients were divided into chemotherapy and allogeneic transplantation groups.The 3-year overall survival (OS) rate and 3-year leukemia-free survival (LFS) rate in IKZF1 mutation group were significantly lower than those of negative group in both transplantation group (42.3％ vs.59.3％;31.2％ vs.50.0％;respectively,both P＜0.05) and chemotherapy group (24.8％ vs.40.0％;19.0％ vs.34.3％;respectively,both P＜0.05).Conclusion IKZF1 mutation is a poor prognostic factor for adult Ph1 positive ALL patients.

Objective To investigate the safety and short-term outcomes of laparoscopic abdominoperineal resection with pelvic peritoneum closure (LARP-PPC) for low rectal cancer.Methods The retrospective cohort study was conducted.The clinicopathological data of 132 patients with low rectal cancer who were admitted to Ruijin Hospital of Shanghai JiaoTong University School of Medicine from January 2014 to December 2017 were collected.There were 81 males and 51 females,aged from 45 to 83 years,with an average age of 62 years.Among the 132 patients,60 undergoing LARP-PPC were allocated into LARP-PPC group,and 72 patients undergoing conventional LARP were allocated into LARP group.All the patients received standardized preoperative and postoperative treatments.Observation indicators:(1) surgical and postoperative conditions;(2) postoperative pathological examination;(3) postoperative complications.The measurement data with normal distribution were expressed as Mean±SD,and the t test was used for comparison between groups.The measurement data with skewed distribution were expressed as M (range),and the Mann-Whitney U test was used for comparison between groups.The count data were expressed as absolute numbers,and the chi-square test or the Fisher exact probability was used for comparison between groups.Mann-Whitney U test was used for comparison of ordinal data between groups.Results (1) Surgery and postoperative conditions:all the patients in the two groups underwent successful surgery without conversion to open surgery.The operation time,volume of intraoperative blood loss,time to first flatus,and time to first liquid intake of the LARP-PPC group were (163±45) minutes,168 mL(range,85-280 mL),2 days(range,1-5 days),3 days(range,2-6 days),versus (155±39) minutes,160 mL(range,100-305 mL),3 days(range,1-7 days),4 days(range,2-7 days) of the LARP group;there was no differencebetween the two group (t =1.113,Z =-1.623,-1.468,-0.321,P＞0.05).The duration of postoperative hospital stay in the LARP-PPC group and the LARP group were 16 days (range,11-21 days) and 19 days (14-24 days),respectively,with a significant difference between the two groups (Z =-5.888,P＜0.05)].In the LARP-PPC group,time of PPC was (13± 3) minutes.(2) Postoperative pathological examination:the length of specimen,the number of lymph node dissection,tumor diameter,cases with high-,middle-,and low-differentiated tumor in the LARP-PPC group was (18±4)cm,16±t5,(3.7±1.4)cm,10,34,16 in the LARP-PPC group,and (18±4)cm,16±5,(3.9±1.5) cm,13,41,18 in the LARP group,showing no significant difference between the two groups (t =0.779,0.390,0.703,Z=-0.267,P＞0.05).(3) Postoperative complications:cases with perineal wound infection,delayed perineal wound healing,intestinal obstruction,and perineal hernia were 2,1,1,0 in the LARP-PPC group,and 12,10,8,6 in the LARP group,showing significant differences between the two groups (x2 =6.137,6.400,P＜0.05).There were 2 and 4 patients with urinary tract infection in the LARP-PPC group and the LARP group,respectively,showing no significant difference between the two groups (P ＞ 0.05).Conclusion LARP-PPC is safe and feasible for the treatment of low rectal cancer,which can significantly reduce postoperative perineal-related complications and consequently shorten postoperative hospital stay.

Four controversial types of simplex reinforcing-reducing manipulation of acupuncture and their possible meanings were summarized to explore several key elements of reinforcing-reducing manipulation of acupuncture, in addition, the simplex reinforcing-reducing manipulation of acupuncture was classified by single factor. It is concluded that the definition of simplex reinforcing-reducing manipulation of acupuncture should try not to include other non-manipulative elements. According to single factor, it can be divided into: needle-oriented reinforcing-reducing manipulation, twisting reinforcing-reducing manipulation, lifting and interpolating reinforcing-reducing manipulation, fast and slow reinforcing-reducing manipulation, breathing reinforcing-reducing manipulation, opening and closing reinforcing-reducing manipulation. In addition, after considering the effect and principle of number reinforcing-reducing manipulation, it can be considered.
