Objective To observe the application of multiple fluorescent PCR (Polymerase Chain Reaction) in the diagnosis and clinical detection of bloodstream infection. Methods 256 blood cultures were collected by the Laboratory Department of Yinzhou People′s Hospital from January 2018 to May 2018, and were detected by multiplex fluorescent PCR. The results of the PCR were compared with the traditional blood culture bacteria identification instrument (traditional blood culture method). The number of positive and negative samples and the number of corresponding samples of the two methods were counted. Then, they analyzed the specificity and sensitivity of multiplex fluorescence PCR in the diagnosis of bloodstream flow infections. Results A total of 18 pathogenic microbes are detected through blood culture and PCR. Multiple fluorescent PCR detects 142 positive samples and 114 negative samples. Among them, 132 samples also show positive through blood culture, and 111 samples show negative. The consistency rate between multiple PCR and traditional blood cultures is 91.8% (235/256). The negative prediction rate of PCR is 97.4% (111/114), sensitivity rate 97.8% (132/135), specificity rate 91.7% (111/121). 10 samples show positive through multiple fluorescence PCR but negative for blood culture, 3 samples show positive through blood culture but negative for PCR. Besides, there are 3 types of pathogens that exceed the detection range of PCR. Conclusions Multiplex PCR method can detect 17 pathogens in blood culture specimens of patients, which can not only optimize the traditional blood culture process, but also greatly shorten the reporting time and improve the detection rate of blood culture methods. Especially for patients treated with antibiotics, it can reduce missed detection and improve the diagnostic rate of bloodstream infections.

Objective To compare the clinical efficacy of minimally invasive surgery and traditional surgery in the treatment of multiple benign mammary lumps.Methods A retrospective study was conducted to select 158 patients with multiple benign breast masses admitted to Yijishan Hospital of Wannan Medical College from July 2016 to February 2018,all of them were female,average age was (28.3 ± 6.6) years old,range from 19 to 51 years old.The patients were divided into minimally invasive group (n =122) and traditional group (n =36) according to different surgical methods.The minimally invasive group was treated by minimally invasive rotary excision,while the traditional group was treated by traditional surgery.The operation time,number of incisions,average length of incisions,cumulative length of incisions and healing time of incisions were compared between the two groups.The incidence of local hematoma,local infection,breast deformity and local residual were compared after operation,and the satisfaction of the two groups was aslo compared.Normal distribution measurements were expressed by mean ± standard deviation (Mean ± SD),independent sample t test was used for inter-group comparison;non-normal distribution measurements were expressed by median (quartile spacing) [M(P25,P75)],Mann-Whitney U test was used for inter-group comparison.Chi-square test or Fisher exact probability test was used to compare the count data between the two groups.Results As compared to the traditional group,the minimally invasive group had shorter operation time (20.0 min vs 40.0 min,Z =-8.590,P < 0.001),less number of incisions (1.0 vs 2.0,Z =-4.423,P <0.001),smaller average surgical incision length (3.8 mm vs 35.5 mm,Z =-9.211,P < 0.001),smaller cumulative surgical incision length (4.0 mm vs 67.2 mm,Z =-9.130,P < 0.001),quicker postoperative recovery (4.0 d vs 7.0 d,Z =-9.334,P < 0.001).There were no significant differences between the two groups in incidence of postoperative hematoma (4.1% vs 2.8%,x2 =0.000,P =1.000),incidence of infection (0 vs 2.8%,P =0.228),incidence of postoperative breast shape change (1.6% vs 2.8%,x2 =0.000,P =1.000),and incidence of residual (0.8% vs 0,P =1.000).Psychological satisfaction of patients in minimally invasive group (95.1%) was significantly higher than that in traditional group (58.3%),the difference was statistically significant (P < 0.001).Conclusions Compared with traditional surgery,the application of minimally invasive surgery in the treatment of multiple benign mammary lumps has many advantages,such as shorter operation time,less number of incisions,smaller surgical incision length,quicker postoperative recovery and higher satisfaction of patients after operation.It has not significantly increased postoperative complications.It is worthy of clinical application and promotion.

Rabdosia (Bl.) Hassk is a medicinal plant rich in enantiomers such as 15α-acetoxyl-6, 11α-epoxy-6α-hydroxy-20-oxo-6, 7-seco-ent-kaur-16-en-1, 7-olide and 15α-dihydroxy-6β-methoxy-6, 7-seco-6, 20-epoxy-1, 7-olide-ent-kaur-16-ene. It has high medicinal value and huge market potential, but the yield from wild Rabdosia (Bl.) Hassk species cannot meet the needs of marketization. Carrying out pollution-free cultivation of Rabdosia rubescens (Hemsl.) Hara and Rabdosia serra (Maxim.) Hara has become the most direct and effective measure to solve this problem in order to ensure the sustainable use of the resources of Rabdosia. This paper summarized a set of non- pollution cultivation system of R. rubescens and R. serra to achieve the"safe, effective, stable and controllable"target.

Moutan Cortex and Paeonia Radix are also traditional Chinese herbal medicines. The market is in great demand. However, the market sales of Moutan Cortex and Paeonia Radix have problems such as pesticide residues, excessive heavy metals and degraded quality, which affect their safety and effectiveness. The establishment of a pollution-free and planting system can effectively reduce the pesticide residue and heavy metal content and improve the quality of the medicinal materials while ensuring the production of Moutan Cortex and Paeonia Radix. The article uses field data which based on P.suffruticosa and P.lactiflora cultivation, combined with growth habits and distribution of origin, this research has developed a pollution-free and planting technology system for P.suffruticosa and P.lactiflora. The system includes planting base regionalization, field management, fertilization, pest control and so on, which provides reference for P.suffruticosa and P.lactiflora.

To assure the clinical quality and requirement of CT shelter used in field environment, the factors related with the practical application were studied. The evaluation indicators of CT equipment were investigated. Based on the technical modification of vehicle shelter CT, the scanning conditions of shelter CT were analyzed. Moreover, the comparative study was done between shelter CT and common CT in hospitals. In result, in order to meet maneuverability application in the field, vehicle shelter CT was restrictive by the field conditions, traffic impacts and running requirement. The application of vehicle shelter CT was affected by the factors, such as mechanical stabilization, moving precision, power fluctuations and variations of temperature and humidity, etc. The results were helpful to improve the clinical quality of vehicle shelter CT and made a base for the quality control study in the future.

Clinical experiments are always used to evaluate the safety and validity of medical devices. The experiments have two types of clinical trying and testing. Ethic review must be done by the ethics committee of the medical department with the qualification of clinical research, and the approval must be made before the experiments. In order to ensure the safety and validity of clinical experiments of medical devices in medical institutions, the contents, process and approval criterions of the ethic review were analyzed and discussed.

To improve the accuracy of finite element method used in medicine field, it is necessary to build the finite element model including real structural information of tissues in human body. In this study, an edge extracting method was introduced on CT image of human body, and the method of building the two-dimensional finite element model from the extracted edges was then raised. Using the above methods, a finite element model of human body containing real structural information can be successfully made. The methods were used for many CT images of hospitals and tested to be simple, fast and adaptable. The study makes a good foundation for further finite element analysis based on medicine images.
