Objective:To investigate the training effect of order-oriented medical students in Yunnan Province of China and related influencing factors and targeted suggestions, and to improve the training effect of order-oriented medical students in residency training bases in Yunnan Province.Methods:The stratified cluster sampling method was used to select 8 general residency training bases, and a questionnaire survey was performed among the 621 order-oriented students in these training bases. Finally, 616 valid questionnaires were collected. SPSS 26.0 was used to perform the two-sample rank sum test, the K-W test, and the ordered multinomial logistic regression analysis.Results:The training effect of the "5+3" order-oriented medical students in Yunnan Province was between generally good (48.29%) and good (45.37%). The effect of the provincial general training base is better than that of the municipal general training base, and most training students at the province level (167, 59.64%) thought that the training effect was good, while most of the training students at the prefecture or municipal level (194, 57.91%) thought that the training effect was generally good. When the teaching level of the teachers can meet the teaching work, the residential training effect of the order-oriented residential training students is well evaluated (197,68.17%). When skill training was carried out by the base at least once a month, most of the order-oriented trainees (96, 48.73%) thought that the training effect was good. The ordered multinomial logistic regression analysis showed that the nature of the base, sex, attitude towards policy, psychological state, teaching competency of teachers, perfection of the fund guarantee system, consistency of training plan with requirements, consistency of training process with requirements, and consistency of teaching activities with requirements were influencing factors for the training effect of "5+3" order-oriented medical students in residency training bases of Yunnan Province ( P<0.05). Conclusions:The training effect of "5+3" order-oriented medical students in residency training bases of Yunnan Province was between generally good and good. The training effect of bases can be improved by strengthening the construction of infrastructure, giving full play to the role of base linkage, perfecting the training plan, improving implementation and execution, building up a perfect fund guarantee system, enhancing the construction of general teaching team, emphasizing skill practice training, and implementing diversified training activities.

OBJECTIVE：To study the current situation of pharmacovigilance work in large ，medium and small-scale pharmaceutical manufacturers in Jiangsu Province ，and to provide reference for the pharmacovigilance development of drug manufacturers with different scales. METHODS ：The situation of pharmacovigilance work in 108 manufacturers in Jiangsu province was investigated through a questionnaire survey and related websites. The pharmacovigilance work （organization，personnel and training，document，computer system ），drug safety monitoring （case report ，regular safety update report ，post-marketing safety research） and drug risk management （signal management ， risk management plan ， risk control measures ， drug safety communication）of different manufacturers were investigated to put forward the suggestions. RESULTS & CONCLUSIONS ：There was no significant difference in the organizational structure （independently established specialized agencies ）among manufacturers of different scales （P＝0.60）. Most of the manufacturers had less than 50％ of the proportion in the independent establishment of specialized institutions for pharmacovigilance. There was significant difference in personnel and training （situation and number of full-time staff in charge ，medical and clinical pharmacy personnel number ），document（formulating training management system ， entrusted management and key monitoring procedures ），computer system （P＜0.05）. There was no difference in the main collection ways of case reports among manufacturers of different scales ；however，the number of independent reports in 2019（P＜ 0.01），the proportion of quality control process for regular safety update reports （P＝0.01），and the proportion of carrying out post-marketing safety research in recent five years （P＜0.01）in large-scale manufacturers were all significantly higher than small- and medium-scale manufacturers. The proportions of large-scale manufacturers （70.00％） and medium-scale manufacturers （84.38％），which considered “lack of technical guidelines ”as an important factor affecting signal management ，were higher than that of small-scale manufacturers （53.57％）（P＝0.01）；the proportions of large-scale manufacturers （60.00％）and medium-scale manufacturers（50.00％），which had carried out risk management plans in the past five years ，were higher than that of small-scale manufacturers（30.36％）（P＝0.04）；the proportion of large-scale manufacturers （50.00％），which adopted the measures in recent 5 year，was higher than medium-scale manufacturers （37.50％）and small-scale manufacturers （25.00％）；the proportions of large-scale manufacturers （70.00％ ） and medium-scale manufacturers （59.38％ ）， which carried out communication for pharmacists，were higher than small-scale manufacturers （32.14％）（P＜0.01）. Large-scale manufacturers outperformed small- and medium-scale manufacturers in terms of pharmacovigilance system ，drug safety monitoring and drug risk management. Large-scale manufacturers had a certain degree of lack of initiative on performing risk management plans ，medium-scale manufacturers on full-time staffs in charge ，and small-scale manufacturers on pharmacovigilance system. So ，it is recommended that large-scale manufacturers take effective control of variety risk as the goal and actively risk management ；medium-scale manufacturers should continuously enhance the awareness of responsibility and improve the investment of resources on pharmacovigilance work ； small-scale manufacturers should pay more attention to improving the pharmacovigilance system and the compliance of specific work.

Objective: To investigate the effect of the lower extremitas abduction brace pads which is designed by our team in helping patient turnover after orthopedic femoral neck fracture, intertrochanteric fracture, femoral head replacement. Methods: Using prospective cohort study to facilitate sampling From October 2016 to August 2017, in an upper third-class hospital of Jiangsu province, we selected 100 patients in Orthopedics dept. No.1 at random as the experimental group and 80 patients in dept. No.2 as the control group. Lower extremitas abduction brace pads were used in experimental group and pillows, backrests and clothes were used in control group. Comfort level, incidence of skin pressure injury, joint dislocation rate and the compliance of the two groups were compared. Results: The number of patients in experimental group who rated the comfort up to 3 (feel a little pain and uncomfortable) was much higher than that in control group (OD value was 5.801, P<0.01), while which rated 1 (feel painful, unbearable and extremely uncomfortable) was lower than that of control group (OD value was 0.168 ,P<0.01) . The ratio of stress injury and dislocation were lower in experimental group (OD value was 0.126, P=0.046). There was no significant difference between two groups in the ratio of dislocation after femoral head replacement (OD value was 0.000, P=0.444) and leg deep vein thrombosis (OD value was 0.000, P=1.000). Conclusion Lower extremitas abduction brace pads can effectively improve the comfort of the patients and reduce the ratio of stress injury.

Ackerman's pattern analysis is an epoch-making leap in the diagnosis of dermatopathology,which embodies a profound understanding of the whole dermatovenereology.To improve the teaching quality of Dermatovenereology for five year clinical medical students,pattern analysis is introduced into course educational practice,and the diseases that scattered throughout the whole textbook and listed in various chapters or sections are reclassified according to its pathological features.Thus the organic connection of related knowledge points and the lateral contrast network between different diseases is constructed by the central tache of dermatopathology,and therefore makes the course more logical and be more beneficial for the undergraduate students to learn and to remember.By the way,the thinking method of pattern analysis will also be an implicit teaching content and imperceptibly instilled to the undergraduate students,and inspired potential and motivation and aroused learning interest,expanded thought train ability to pursue advanced and further studies.

Objective To survey the current situation and influencing factors of willingness to attend assistant general practitioner training among junior medical college students in Yunnan Province.Methods A questionnaire survey and interview on the willingness to attend the training of assistant general practitioner was conducted from May 2017 to June 2017 in Yunnan Province,1 800 students from 6 junior medical colleges were selected as participants by stratified cluster sampling method.Results A total of 1 800 questionnaires were distributed and 1 710 were collected,of which 1 634 were valid with a recovery rate of 95.00％ and an effective rate of 95.56％.The results showed that 43.21％ (706/1 634) participants were not aware of the relevant training policies,while there were significant differences among participants in the different grades and types of college (public or private) (Z=-0.899,8.658,-13.954;P＜0.05);83.17％ (1 379 / 1 634) participants were willing to sign up for an assistant general practitioner training after graduation,while there were significant differences among participants in different ethnic groups,grades,household register sites,types of college,and family income (P＜0.05).Total of 1 300 (79.56％) chose to work as a general practitioner in rural grassroots institutions after graduation,and 984 (60.22％) chose to become a specialist after graduation.Unconditional logistic regression analysis showed that the types of medical college,attitude towards the training policy,the intension to work in grassroots level or to work in private hospitals were influencing factors for willingness to attend the assistant general practitioner training among medical students(B=1.654,3.764,1.361,-0.569;P＜0.05).Conclusion The survey shows that the policy awareness and the willingness to attend assistant general practitioner training for student in junior medical college in Yunnan Province are not high,and the policy publicity and the career guidance need to be strengthened.

Because of the nanometre resolution, piconewton force sensitivity, label-free technique and the ability to operate in liquid environments, atomic force microscopy (AFM) has emerged as a powerful tool to explore the biofilm development processes. AFM provides three-dimensional topography and structural details of biofilm surfaces under in-situ conditions. It also helps to generate key information on the mechanical properties of biofilm surfaces, such as elasticity and stickiness. Additionally, single-molecule and single-cell force spectroscopies can be applied to measure the strength of adhesion, attraction, and repulsion forces between cell-solid and cell-cell surfaces. This paper outlined the basic principle of AFM technique and introduced recent advances in the application of AFM for the investigation of ultra-morphological, mechanical and interactive properties of biofilms. Furthermore, the existing problems and future prospects were discussed.

Objective To investigate the effects of hospital-community-family continuing nursing in patients with type 2 diabetes mellitus on the control of blood glucose and diet.Methods A total of 118 patients with type 2 diabetes in the endocrinology department of Jiangsu Province Hospital of TCM from March 2015 to March 2016 were selected using convenience sampling methods and divided into control group and experimental group using random number table, with 59 cases in each group. Patients in the control group were given endocrinology specialist nursing and routine discharge guidance, while patients in the experimental group were given endocrinology specialist nursing and hospital-community-family continuing nursing discharge guidance. The control effects of blood glucose and diet of patients were compared between the two groups.Results After the intervention for six months, the control level of blood glucose of patients in the experimental group was significantly better than that in the control group (t=3.98,P<0.05). The food intake compliance of the patients in the experimental group were better than that in the control group, with a statistically significant difference between the two groups (P<0.05).Conclusions The implementation of hospital-community-family continuing nursing in the patients with type 2 diabetes mellitus is beneficial to the blood glucose control and improvement of diet of patients.

Objective To analyze the status of quality of life and influencing factors in patients with chronic gastritis. Methods 124 chronic gastritis patients were measured by the Chronic Gastritis scale of Quality of Life Instruments for Chronic Disease (QLICD-CG) before and after treatments. The scores were compared by paired t-test,and the influencing factors were analyzed by independent sample t-test and One-Way ANOVA. Results There were significant differences in all domains and total scores between the before and after treatments. The quality of life of chronic gastritis patients were influenced by treatments,gender,marital status,occupation and economic conditions ( <0.05) . Conclusion While reasonable treatment is very important to improve quality of life of the chronic gastritis patients, some influencing factors should be addressed, and mental health education and psychological service should be strengthened.

Through this research a lentiviral vector expressing the gene of folate-binding protein-1 (FOLR1) was constructed and the corrsponding expression products were identified. Firstly, full-length of the FORL1 gene was amplified by PCR and cloned into the plasmid pWPI. Then it was further confirmed by PCR and sequencing. Secondly, after the recombinant pWPI and its helper plasmid co-transfected the virus packaging 293T cells, SKOV3 cells were infected with the virus particles and sorted by flow cytometry. Thirdly, the FOLR1 gene was detected by RT-PCR and its protein expression was detected by Western blot. Finally, the recombinant expression vector was successfully constructed, and lentiviruses were successfully packaged by the 293T cells. A great quantity of green fluorescent cells could be seen after the SKOV3 cells were effectively infected with the lentiviruses carrying the FOLR1 gene. The sorting could be done and detected by cytometrying the FORL1 gene and its stable expression by the two methods above, which laid experimental foundation for exploring its biological function in ovarian cancers.
