OBJECTIVE To find out the clinic air disinfectant effect and the damage to human body between air aerosol sprayer of hydrogen peroxide and peracetic acid. METHODS New ninety eight sickrooms were randomly disported into two groups. The group of using peracetic acid was a control one. Then the clinic air disinfectant effect and the damage between two groups were observed. RESULTS After thirty minutes, to sample through flat exposure method. The total number of bacteria of two groups reached the third grade of environment eligible standard without pathogenic bacteria being checked. Hydrogen peroxide had not obvious mucous membrane stimulation and hypersusceptible reaction to human body. But peracetic acid had mucous membrane stimulation and hypersusceptible reaction to human body. CONCLUSIONS The air disinfection using aerosol sprayer is still an available method when there are no person in new sickrooms or extended sickrooms. At present, some chemical disinfectant methods that have strong poisonous reactions and pollute environment, such as peracetic acid, have been restricted to be used because of thrill, toxicity to human body and causticity to goods. But the method of dynamic air disinfectant machine that can be used in the situation of ventilation, dust catching, decontaminating, and ultraviolet irradiation, at the same time having someone has became a new idea of air disinfection.

Objective: To investigate the clinical effect of acupuncture therapy and Tuina therapy in treating cervicogenic headache. Method: Forty inpatients, were divided into acupuncture and Tuina group(experiment group, n= 20), and Tuina and acupoint injection group(controlled group, n = 20) with random number table. Patients in the experimental group were firstly needled Fengchi (GB 20, major acupoint), Taiyang (Ex-HN 5), Baihui (GV 20), Shuaigu (GB 8),and Jiaji (Ex-B 2) around the affected cervical vertebrae, and applied Tuina treatment.Patients in the controlled group were treated with Tuina treatment, and then injection in Fengchi (GB 20) with 500 μg of Methycobal. Before and after treatment, all patients in both groups were evaluated with Evaluation Scale for Cervicogenic Headache. Result: After treatment, score of each item of patients in both two groups were enhanced (P＜0.01), and compared with patients in the controlled group, patients in the experimental group had higher scores of headache(13.1±3.02 vs 10.8±2.36, P＜ 0.01), daily life and working (3.3±0.66 vs 2.6±0.79, P ＜ 0.01), mental state and social adjustment (3.1±0.85 vs 2.1±0.85, P＜ 0.05), and total points (24.6±4.36 vs 20.3± 2.53, P＜ 0.01). Conclusion: Acupuncture combining with Tuina had better effects than acupoint with Tuina, and could effectively relieve pain, and enhance quality of life and ability of social adjustment in patients with cervicogenic headache.

OBJECTIVE To discuss the reasons of causing mistakes in the nosocomial infection reports.METHODS We collected 183 cases with inaccurate reports and analyzed them by the prospective method.RESULTS The major reasons of causing the inaccurate nosocomial infection reports were the ill-defined infection time,inaccurate diagnostic standard,and the lack of clinic training.CONCLUSIONS It can reduce the inaccurate nosocomial infection reports,advance the level of nosocomical infection diagnosis,and improve the work efficiency through special training,in paralleling with the manager of nosocomial infection going deep into sickroom and communicating with clinicians.

OBJECTIVE To know the real condition of the prevalence of nosocomial infection(NI) in our hospital,in order to enhance the consciousness of nosocomial infection control in whole staff,so that this work will be done well.METHODS We got the data through bed-side examination and medical records and made a statistic analysis.RESULTS Among 926 investigated patients,59 patients(6.37%) had 60 cases(6.48%) NI.Departments with high risk were for hematology,neurosurgery,and Chinese-Western combination surgery.The common NI sites were the lower respiratory tract,urinary tract and surgical sites;Pseudomonas aeruginosa was a main pathogen for the lower respiratory tract.The antibiotic use rate was 40.39%.The high risk factors were patients with unconsciousness,undergoing tracheotomy or urethral catheterization and so on.The postoperative use appeared to be higher than usual.The antibiotics used included 42 kinds.CONCLUSIONS It is recommended that specific surveillance be conducted in Departments with high risk for nosocomial infection,the wide-spectrum antibiotics should be stressed in order to reduce drug resistance and nosocomial infection.

Objective To analyze the risks and related influencing factors of early screening for lung cancer,and to study prognostic factors based on survival conditions,in order to ultimately provide baseline data for the prevention and treatment of lung cancer.Methods A cluster sampling method was used to select 40 to 75 year old registered residence residents in 10 districts and 6 counties of Zhengzhou City in 2020 as screening objects.Through voluntary participation and filling in evaluation questionnaires,high-risk groups of lung cancer were evalu-ated,and then three screening tests(tumor markers,low-dose spiral CT and lung function)were performed on high-risk groups.Finally,we will adopt an active and passive follow-up approach to collect information on diag-nosed lung cancer patients.Statistically describe the screening data and describe the epidemiological results of different characteristic populations;Using multivariate logistic regression method for statistical analysis,compare the differences in various results of different factors.Results 50128 cases of early screening for lung cancer in Zhengzhou City were evaluated in 2020,with a completion rate of 100.26%.The average age of the survey was(59.86±17.67)years old,and the gender ratio was 0.81∶1.The high-risk detection rate is 30.15%.Multivariate logistic regression analysis showed that males(smoking)(OR=5.43,95%CI:5.20～5.67),individuals with a history of tobacco exposure(OR=3.82,95%CI:3.67～3.98),first-degree relatives who had previously suffered from lung cancer(OR=12.06,95%CI:11.02～13.20),and other populations were more susceptible to lung cancer(all P<0.05).Conclusion Male(smoking),exposure to secondhand smoke,cancer in first-degree relatives,previous diagnosis of other tumors,symptoms of lung infection,"chest tightness,shortness of breath,and difficulty breathing in daily life",and"significant psychological trauma in the past 3 years"are independent risk factors for lung cancer,which should be given special attention and effective intervention measures should be taken.

Yuhua91 is a new peanut variety with high oleic acid content bred by Qingdao Agricultural University. The crossing was conducted with Luhua11 as female parent and with Kainong1715, an F435-type variety with high oleic acid content as male parent. The real F1 hybrids were screened by sequencing on PCR amplification products, and those homozygotes with bb genotype in F2 populations were screened by the same sequencing method as above. The content of oleic and linoleic acid was measured on the kernels harvested from F2 single plants by near infrared ray method, and those kernels whose content of oleic was above 80%, oleic and linoleic acid ratio was above 10.0 were obtained and planted into a row, with pedigree method for subsequent selection breeding. Yuhua91 has some characters of small pod, light and obvious pod texture, 148.06 g per 100 pods, 63.31 g per 100 kernels, 75.15% shelling percentage, long elliptic seed kernel, pink seed coat, without crack, white endotesta. Its content of protein, oil, oleic acid, linoleic acid and palmitic acid was 26.57%, 52.72%, 80.40%, 2.50% and 5.57% respectively. Yuhua91 has other characters of strong seedlings, compact pod areas, and moderate resistance to leaf spot disease and bacterial wilt. Average pod yield is 215.79 kg per Mu, 15.27% higher than the control variety Huayu20. Average seed kernels yield is 157.33 kg per Mu, 21.64% higher than the control variety Huayu20. Yuhua 91 has been registered on department of agriculture in 2018, and the registration No. is GPD peanut (2018) 370210, fit for growing in Shandong Province.
