ObjectiveTo investigate the efficiency of autologous transplantation of peripheral blood stem cells for treatment of patients with diabetic lower limb ischemia.MethodsEighteen patients of type 2 diabetes with diabetic lower limb ischemia (30 legs) were treated by autologous transplantation of peripheral blood stem cells.ResultsThe limb pain, cool feeling and numbness feeling improved significantly after PBSC transplantation,the improvement rate were 96.7％, 100.0％ and 95.8％ respectively.Intermittent claudication was also relieved significantly, total remission rate was 76.9％.The ABI and TcPO2 of patients increased significantly at 3 months after transplantation.After the transplantation ABI raised from 0.60 ± 0.11 to 0.71 ±0.12(t =-6.882, P ＜ 0.01) .93.3％ of patients' TcPO2 raised in different degrees.The foot infections were well controlled.Ulcer or toes gangrene got better or healed.No obvious complications or adverse reaction were observed after the transplantation.ConclusionAutologous transplantation of peripheral blood stem cells shows to be a simple, safe and effective method in treating patients with diabetic lower limb ischemia.

[Objective]To explore the relationship between peripheral arterial disease(PAD)and diabetic retinopathy(DR)in type 2 diabetes patients.[Methods]A total of 99 patients diagnosed with PAD were classified into grade 1-3 by their total scores of peripheral arterial stenosis assessed by color doppler ultrasound examinations,where the degree of stenosis 30% ~ 49% scored 0, 50%~99%scored 1,lumen occlusion(i.e. degree of stenosis 100%)scored 2,and therefore the total score 0-2 was categorized into Grade 1 ,3~4 into Grade 2 ,5~12 into Grade 3. The bilateral anterior tibial artery ,posterior tibial artery and dorsalis pedis artery of these patients were analyzed. The presence of diabetic retinopathy(DR)was graded from retinal photographs using a standard protocol.[Results]Among 99 cases of type 2 diabetic patients with peripheral arterial disease ,58.6%of them were male with average age of 67.3 ± 7.9 years old. Patients of Grade 1,Grade2,Grade 3 lesion accounted for 45.4%,30.3%,24.2%,respectively. Age, gender,smoking history,SBP,DBP,BMI,FBG,TC,TG,LDL-C,HDL-C,HbA1C among 3 groups were not statistically signifi-cant. The associations of DM duration and HbA1C value were significantly larger in DR than in PAD. The proportion of DR patients increased with the severity degree of PAD(p for trend=0.004). Degree of stenosis Grade 2 and Grade 3 could be predictive for DR.[Conclusions]DR is associated with the severity degree of PAD in type 2 diabetes patients as evaluated by duplex ultrasonography.Degree of stenosis Grade 2 and 3 could be used for screening or finding DR. Strategies for optimum treatment and early prevention are needed.

Most drugs taste bitter and irritating, resulting in poor compliance of patients, and the bad odor affects the therapeutic effect. The successful research and development of a drug should not only conform to the five quality characteristics of effectiveness, stability, safety, uniformity and economy, but also the compliance of patients to drugs with bad odor. The development of taste masking techniques is critical for bitter drugs.This review describes the principles, advantages and drawbacks of traditional taste masking techniques, and introduces the mechanism and application of novel taste masking techniques, such as melt granulation, hot melt extrusion, 3D printing, drug complex preparation, and bitter taste inhibitors. The in vitro evaluation methods of drug taste masking effect, such as functional magnetic resonance imaging, in vitro dissolution, and electronic tongue technology, are described. And introduce in vivo evaluation methods, such as animal and human taste, in the field of taste masking effect. A new strategy of BP neural network prediction model for drug taste evaluation is proposed, with a view to providing theoretical reference for the future research on drug taste masking.

Objective:To understand the attitude of clinical nurses in a ClassⅢ Grade A hospital in Shanghai towards the implementation of the advance fixed scheduling model and to explore the influencing factors of whether nurses are willing to try the advance fixed scheduling model, so as to lay the foundation for later development in clinical practice.Methods:Mixed design was used to study. In the quantitative study, a cross-sectional survey of 1 326 nurses in a comprehensive Class Ⅲ Grade A hospital in Shanghai was conducted with a self-made questionnaire from September to October 2018 with cluster sampling method. And multivariate Logistic regression was used to analyze the influencing factors of the willingness of nurses to try the advance fixed scheduling model. A total of 1 326 questionnaires were distributed and 1 326 were effectively collected, with an effective recovery rate of 100.0%. In the qualitative study, 12 nurses from a comprehensive Class Ⅲ Grade A hospital in Shanghai from September to December 2018 were selected for semi-structured in-depth interviews with the purposive sampling method, so as to deeply understand the attitude and reasons of clinical nurses towards the implementation of the advance fixed scheduling model. And Colaizzi phenomenological analysis method was used to collate and analyze the interview data.Results:A total of 49.2% (653/1 326) of the nurses heard of the advance fixed scheduling model and 67.5% (896/1 326) of the nurses expressed their willingness to try the advance fixed scheduling model. The results of multivariate Logistic regression analysis showed that non-emergency department, whether they had children, whether they heard of the advance scheduling model and whether they believed that shifts had a great effect on life were influencing factors of the willingness of nurses to try the advance fixed scheduling model ( P<0.05) . The results of qualitative interviews showed that some nurses supported the advance fixed scheduling model and looked forward to a more reasonable arrangement of their study and life under the new work model, while some nurses feared change, and worried about their competence, fairness issues and non-support from their family members. Conclusions:Clinical nurses have a general attitude towards the advanced fixed scheduling model. In clinical practice in the future, some nurses who are willing to try can be recruited to implement the advance fixed scheduling model and their working status, satisfaction and quality of work can be dynamically monitored to provide an empirical basis for the new nursing manpower management model.

Objective:To explore the knowledge and attitude of cardiopulmonary resuscitation (CPR) in community residents in Shanghai and analyze the influencing factors.Methods:The residents in 16 communities in Shanghai were selected by convenient sampling and investigated from November 2018 to June 2019, and a total of 714 valid questionnaires were recovered. The residents' CPR knowledge and attitude were analyzed descriptively, and multiple linear regression was used to analyze the influencing factors.Results:The total score of CPR knowledge among the 714 community residents in Shanghai was (24.58±7.80) , with a passing rate of 36.13% (258/714) , and the passing rate of "artificial respiration knowledge" was the lowest, which was 38.66% (276/714) . The total score of the residents' CPR attitude was (40.95±5.18) , and the average scores of "attitude to learning CPR" and "attitude to implementing CPR" were (3.60±0.45) and (3.22±0.50) , respectively. Analysis of the influencing factors showed that gender, age, education level, conscious health status, whether they have heard of CPR, whether they have received CPR training, and whether they have encountered emergency rescue communities were the influencing factors to the community residents' CPR knowledge and attitude ( P < 0.05) . Conclusions:The overall CPR knowledge level of the community residents in Shanghai is relatively low, and the residents prefer to learn CPR and implement CPR for their relatives and friends, rather than strangers. Younger, better conscious health status, and having heard of CPR can help the residents improve their CPR knowledge and attitude, while women, higher education level, and residents who have encountered emergency rescue communities have better CPR knowledge. The CPR training has a positive effect on the residents' attitude to learning and implementing CPR. Future CPR training needs to increase the training intensity and duration, and help the residents to improve the level of CPR knowledge and attitude.

Objective: To investigate the effects of sinomenine on brain edema and the expression of aquaporin 4 (AQP-4) and aquaporin 5 (AQP-5) in rats with acute brain injury. Methods: According to random number table method, rats were divided into sham operation group, model group, low-dose sinomenine group, high-dose sinomenine group, 20 in each group. In addition to the sham operation group, the rat brain injury model was established by Feeney free falling impact method. Rats in low and high dose of sinomenine group were given sinomenine 30, 60 mg/kg by intraperitoneal injection, and the sham operation group and model group were injected intraperitoneally with the same volume of normal saline, once per day for 7 days. Histopathological changes in each group were observed by HE staining and electron microscope. Western blot and RT-PCR were used to detect AQP-4 and AQP-5 protein and gene expression in brain tissue. Results: The pathological results showed that the nerve cells in the model group were loosely arranged, disordered in hierarchy, some cells appear to have degenerated. The degeneration and necrosis of nerve cells in the low and high dose sinomenine group were less than those in the model group. Compared to the model group, the expression of AQP-4 (0.74 ± 0.13, 0.49 ± 0.11 vs. 1.30 ± 0.21), AQP-5 (0.98 ± 0.07, 0.45 ± 0.10 vs. 1.47 ± 0.18) in the low dose and high dose sinomenine group significantly decreased (P<0.05). The expression of AQP-4 (1.48 ± 0.18, 1.26 ± 0.12 vs. 2.04 ± 0.14), AQP-5 (1.31 ± 0.17, 1.20 ± 0.11 vs. 1.87 ± 0.15) mRNA in the low dose and high dose sinomenine group significantly decreased (P<0.05). Conclusions Sinomenine could alleviate cerebral injury by lowering the expression of AQP-4 and AQP-5.

Objective:To standardize the management of auditory hallucination symptoms in inpatients with mental illness and develop an expert consensus on the management of auditory hallucinations in hospitalized psychiatric patients.Methods:From March 2023 to July 2023, the Mental Health Committee of the Chinese Nursing Association focused on the key issues in the management of auditory hallucinations symptoms in inpatients with mental illness, based on clinical practice, using literature analysis combined with the work experience of mental health experts, and formed the first draft of the expert consensus on the management of auditory hallucinations in inpatients with mental illness (hereinafter referred to as the consensus). Through 3 rounds of expert consultation and 3 rounds of expert demonstration meeting, the draft was adjusted, revised, and improved.Results:37 experts were included in the Delphi expert consultation, 1 male and 36 females with 39-67(51.48 ± 6.61) years old. The positive coefficients of experts in 3 rounds of Delphi expert consultations were all 100%, and the degrees of expert authority were 0.924, 0.938 and 0.949, respectively. The average importance value of each item was higher than 4.00, the variation coefficient of each item was less than 0.25. The Kendall harmony coefficient of the experts were 0.179, 0.195 and 0.198, respectively (all P<0.05). There were 15, 12, 12 experts in the first, seeond, third rounds of expert demonstration meeting. Finally, a consensus was reached on the recommendation of 4 parts, included auditory hallucination assessment, management format, symptom management implementation, and precautions. Conclusions:The consensus covers all parts of the management of auditory hallucination symptoms in hospitalized patients with mental disorders, which is practical and scientific. It is helpful to guide mental health professionals to standardize the management of auditory hallucination symptoms, improve the quality of nursing and ensure the safety of patients.

Objective:To investigate the treatment options for multiple myeloma patients with central nervous system involvement (CNS-MM) , as well as their clinical characteristics and prognostic factors.Methods:Between January 2011 and January 2022 our center diagnosed 18 people with CNS-MM. A retrospective analysis was done on the clinical information from the initial diagnosis and central nervous system involvement, and it was compared to 1∶3 matched newly diagnosed MM from the same period. Analysis was done on the clinical characteristics and survival rates of the two groups.Results:In patients with CNS-MM, the median time of onset was 14.2 (0.9-79.6) months and the median overall survival (OS) was 30.5 months from initial diagnosis and only 3.8 months in patients after CNS involvement. The CNS-MM patients showed more IgD type ( P=0.010) , severer anemia ( P=0.014) , a higher proportion of bone marrow plasma cells ( P=0.013) , more extramedullary lesions ( P=0.001) , and increased lactic dehydrogenase (LDH) ( P=0.009) when compared to the control group. Lenalidomide or pomalidomide-based combinations had higher rates of hematology and CNS remission than bortezomib or daratumumab-based regimens (75.0% vs 16.7% , P=0.019) . Patients who received IMiD-based regimens and had 2 high-risk factors at initial diagnosis (high LDH and extramedullary lesions) had a significantly lower incidence of CNS-MM ( P=0.026) . At the initial diagnosis, LDH ( P=0.008, HR=7.319, 95% CI 1.663-32.219) and extramedullary lesions ( P=0.006, HR=8.054, 95% CI 1.828-35.486) were independent risk factors for the occurrence of CNS-MM. Conclusion:Patients with CNS-MM had a poor prognosis. Patients with high LDH or extramedullary lesions at the time of the initial diagnosis are more likely to have CNS-MM. The prognosis of this patient may be improved by immunoregulator-based therapy.
