ABSTRACT

Objective:To survey the training requirements for doctoral candidates in general practice.Methods:A questionnaire survey was conducted to investigate the requirements for general practice doctorate training; the items included the training target, training objectives and training contents. A total of 130 stakeholders of general practice participated in the survey, including administrators in health committees, general practice educators of medical schools, general practitioners in hospital and community health service centers and students in general medicine. The participants were divided into training unit group ( n=42), employer group ( n=42) and doctor and student group ( n=46). Results:Among all training objectives, the training "general medicine scientific research ability" ranked the first (121, 93.1%); while 114 (87.7%) respondents believed that the training target should be the leading talents in general medicine. Regarding the content of clinical competence training, 86 (66.1%) respondents believed that there was a lack of medical care training for whole life-cycle and whole population currently. The training requirement for acute disease management and referral competence in employer group was significantly higher than the training unit group (χ2=25.73, P<0.01) and the doctor and student group (χ2=24.37, P<0.01). Most survey respondents believed that the doctorate candidates in general medicine should focus on scientific research training in community clinical medicine ( n=110, 84.6%), community preventive medicine and epidemiology ( n=114, 87.7%); 117 (90.0%) respondents believed that clinical research design and methodology training should be strengthened, and 125 (96.2%) respondents believed that clinical teaching thinking training should be strengthened; 108 (83.1%) survey respondents believed that it is necessary for their units to recruit personnel with doctoral degree in general medicine. Conclusion:The training of doctorate candidates in general medicine should aim at cultivating leading talents in general medicine, strengthen the training of clinical scientific research capabilities, and focus on cultivating their comprehensive abilities of "being able to research, be good at teaching, and understand management", so that they can truly become the leaders in this discipline.

ABSTRACT

Post-traumatic stress disorder(PTSD) caused by various natural disasters and man-made events has gradually become the highlight of neuroscientists. Sleep disorders after PTSD can impair the effect of treatment and affect the patient's prognosis. In addition, treatment for sleep problems can be effective in improving outcomes for people with PTSD, which indicates that it is significant to pay attention to sleep disorders after PTSD. However, current studies have focused more on the incidence of PTSD and severity of related symptoms after a traumatic event, and less on the occurrence and mechanism of sleep disorders after PTSD. A number of articles on stress and sleep disorders published in recent years provide reliable clues to understand the probable mechanisms of sleep disorders after PTSD. After summarizing the latest research results, this article finds that the occurrence of sleep disorder after PTSD may be related to the changes of connectivity between insula, hippocampus and medial-prefrontal cortex. Apart from that, decline in the mean phase difference of slow spindles in PTSD patients may reflect pathological changes in the thalamic cortical circuit, which may contribute to the objective diagnosis of PTSD and the development of sleep-focused interventions. This paper provides a systematic review of changes in sleep characteristics and possible neural circuitry mechanisms after PTSD from clinical and basic perspectives, which may provide potential directions for future researches on the pathological mechanism of sleep disorders after PTSD and screening novel intervention targets.

ABSTRACT

Objective:To evaluate the safety and effectiveness of the accurate puncture during sacral neuromodulation (SNM) guided with 3D printing navigation template based on reconstruction techniques using fusing sacral CT and MRI images.Methods:Totally 42 patients operated with SNM were selected in Renji Hospital, School of Medicine, Shanghai Jiaotong University from July 2016 to August 2017. The patients were randomly divided into control group ( n=22) and experimental group ( n=20) using random number table. The conventional cross-positioning technique under X-ray was used for puncture during SNM in the control group. While in the experimental group, the sacral CT and MRI images were fused for reconstruction and design of the navigation template, printed by 3D technique for the puncture in SNM. The times of punctures, the average time for puncture operation, the time of intraoperative testing of the stimulator device, the minimum onset voltage of the stimulator, the X-ray radiation dose, postoperative curative effect (rate of secondary transformation) and the incidence rate of complications were compared between the two methods using independent-simple t test or χ 2 test. Results:Compared to control group, fewer times of punctures, shorter time needed for puncture operation, shorter time of intraoperative testing of the stimulator, smaller radiation dose and minimum effective voltage were found in the experimental group ( P<0.05). There were 15 and 16 patients who completed the secondary transformation in the control group and experimental group, and there was no significant difference between the two groups (χ2=0.757, P=0.384). There were 3 cases of complications in the control group, including 2 cases of infection and 1 case of bleeding, while no complications in the experimental group. Conclusions:CT and MRI images fusion reconstruction-guided 3D printing navigation template can help perform accurate and safe punctures in SNM. Compared to conventional puncture positioned under X-ray, it can effectively improve the puncture efficiency, and reduce the radiation dose in the operation.

ABSTRACT

In medical follow-up studies, longitudinal data and survival data are often accompanied and associated with each other, thus respective analysis of longitudinal and survival data might lead to biased results. Joint model can correct deviations, improve the efficiency of parameter estimation and provide effective inferences by simultaneously processing longitudinal and survival data. It is a popular method in medical research. Joint model has made much progress, whereas the literature about the joint model and its application is limited in China. This paper summarizes the main idea, basic framework, parameter estimation methods of random effect joint model and introduces the analysis on AIDS data set based on the R software package 'JM’ to clarify the advantages of the joint model in processing medical follow-up data and promote the use of the joint model in clinical research.

ABSTRACT

BACKGROUND:Polysulfone membrane holds good anti-biodegradation ability, but how to use it to prepare hol ow fiber dialysis membrane and its blood compatibility have not been ful y understood. OBJECTIVE:To study the preparation, transfer property and biocompatibility of hol ow fiber dialysis membrane. METHODS:With polysulfone as the film material, diethylene glycol as the porogen, polyvinyl pyrrolidone as the modifier, N, N-dimethylacetamide as the solvent, and the hol ow fiber dialysis membrane was prepared using nonsolvent-induced phase separation. The performance was measured using scanning electron microscopy, ultra-depth three-dimensional microscope imaging and porosity test;the transfer parameters including reject rate and water flux were detected by ultrafiltration device;the blood compatibility was determined through hemolysis test, dynamic clotting time test and platelet adhesion test. Type II medical polyurethane material served as negative control. RESULTS AND CONCLUSION:The section of hol ow fiber dialysis membrane was asymmetric. 17%dialysis membrane showed a porous middle layer, while 19%, 21%and 23%membrane showed a sponge-like middle layer. Under the same membrane area, the density of fiber dialysis membrane was significantly lower than that of the negative control material, and the porosity of fiber dialysis membrane was significantly higher than that of the negative control material (P<0.05). The water volume and water flux of the hol ow fiber dialysis membrane were significantly higher than those of the negative control material (P<0.05). Results from three hemolytic tests showed that the average absorbance values and hemolysis rate of the hol ow fiber dialysis membrane were significantly higher than those of the negative control material (P<0.05). The dynamic clotting time test and the platelet adhesion test revealed that the dynamic clotting time of hol ow fiber dialysis membrane at 20, 40 and 70 minutes was significantly shorter than that of the negative control material (P<0.05). These results suggest that polysiloxane can be used as the membrane material to prepare hol ow fiber dialysis membrane using nonsolvent-induced phase separation, and holds a good biocompatibility, blood compatibility and transfer efficiency.

ABSTRACT

Tumor is a neoplasm formed by the abnormal proliferation of local tissue cells under the effects of different tumorigenic factors. Tumor-therapy has always been a difficult clinical issue, while regular cancer treatments, such as radiotherapy, chemotherapy and surgery, have obvious limitations. Earlier studies have shown that some obligate anaerobes or facultative anaerobes have anti-tumor effects, for example, Salmonella typhymurium as facultative anaerobic bacteria can selectively colonize tumors and inhibit their growth. Besides, Salmonella has many advantages in tumor-therapy. In the past decade or two, many researchers have carried out genetic manipulation to attenuate the virulence of Salmonella, to improve their specificity of tumor colonization and specially to use attenuated Salmonella as carriers to deliver a variety of anti-tumor therapeutic molecules, and these genetically modified Salmonella have shown good anti-tumor effects in many animal experiments. Along with further research of Salmonella-mediated antitumor treatment, applications of genetically modified Salmonella for more effective tumor-therapy are promising. We reviewed the anti-tumor mechanisms of Salmonella, the research progress in tumor-therapy using genetically modified Salmonella, and current problems and possible solutions.

ABSTRACT

Objective:To study the molecular composition of bismuth potassium citrate. Methods:The content of bismuth was de-termined using a volumetric method, the content of potassium was determined by atomic absorption spectrometry, and the content of cit-rate root was determined by ion chromatography. The structure was predicted using 1 HNMR and the crystal structure was studied using X-diffraction test and scanning electron microscopy. The changes in the percentage ratio of the three components were investigated by accelerated stability tests. Results:On the dried basis, the percentage of the three molecular components was bismuth of 35%-38%, potassium of 7%-11% and root citrate of 49%-52%. The NMR spectra and the data indicated that the product had three isomers with the molecular structure of bismuth∶potassium∶root citrate=2∶2∶2. The X-diffraction test and SEM showed that the three forms of amor-phous, monocrystalline and polycrystalline might exist. The percentage ratio of the three elements before and after the stability test was basically stable. Conclusion:Bismuth potassium citrate may have three crystal forms with the percentage of the three structure parts within a certain range, and the structure is relatively stable.

ABSTRACT

ObjectiveThe aim of this study is to investigate whether oral administration of collagen Ⅱ peptide (250-270)[C Ⅱ (250-270)]-cholera toxin B subunit (CTB)complex could effectively set up oral immune tolerance to collagen-induced arthritis (CIA) in mice. MethodsDBA/1 mice were divided into Ⅰ, Ⅱ, Ⅲ and Ⅳgroups. Group Ⅰ was normal control group. Collagen type Ⅱ emulsified in Freund's complete adjuvant were injected to mice of groups Ⅱ , Ⅲ and Ⅳ twice from the base of the tail. Mice of group Ⅲ were fed with C Ⅱ (250-270)-CTB covalent complex twice after the arthritis was developed. Mice of group Ⅳ were fed with C Ⅱ(250-270) and CTB mix at the 14th day after primary immunization. Visual scores and histopathologic scores of arthritis were recorded. The frequencies of arthritis between the groups were compared usingFisher's exact test. The clinical and histological severity of arthritis were analyzed by ANOVA.Results The frequencies of arthritis in groups Ⅰ , Ⅱ , Ⅲ and Ⅳ were 0, 100%, 100% and 25% respectively. Average accumulative scores of arthritis were 0, 5.0±1.7, 10.8±2.8 and 1.0±2.0 respectively. Average accum-ulative histopathological scores of arthritis were 0, 16±8, 32±13 and 7±6 respectively. Conclusion Oral administration of C Ⅱ (250-270) and CTB mix in arthritis mice after C Ⅱ immunization can suppress the onset and severity of arthritis. Oral administration of C Ⅱ (250-270)-CTB covalent complex in the acute stage of arthritis can accelerate arthritis.

ABSTRACT

OBJECTIVE: To analyze the utilization of traditional Chinese medicine (TCM) injections in our hospital in order to provide reference for clinical rational use of TCM injection. METHODS: The utilization of TCM injection in our hospital from 2006 to 2008 was statistically analyzed in terms of consumption sum, DDDs and its order. RESULTS: The consumption sum and DDDs of TCM injection in our hospital increased year by year, especially stasis-removing agents and antitumor drug. Over the 3 years the proportion of consumption sum of TCM injections in the total consumption sum were 57.3%, 59.4% and 55.9%, respectively. There was poor synchrony between consumption sum order and DDDs order. CONCLUSION: TCM injections are used rationally in our hospital. In addition, safety reevaluation of TCM injection should be improved.
