ABSTRACT
With the improvement of people's living standards and the increasing aging population， the incidence of cardiovascular diseases has sharply risen， making it the leading cause of death and a major "killer" for humans. The prevention and treatment of cardiovascular diseases still face severe challenges. Shenmai injection （SMI）， a Chinese medicinal preparation， is widely used in the prevention and treatment of cardiovascular diseases because of its individualized advantages in syndrome differentiation and definite efficacy. Meanwhile， its pharmacological effects and related mechanism are becoming increasingly clear. Modern research shows that SMI can exert cardioprotective effects by reducing myocardial inflammatory response， alleviating oxidative stress， inhibiting myocardial cell apoptosis， improving microcirculatory dysfunction after myocardial ischemia-reperfusion， protecting mitochondrial structure and function， inhibiting ventricular remodeling， reducing drug-induced cardiotoxicity， and possessing antiviral properties. Additionally， it can produce cardiovascular protection by relaxing blood vessels， protecting endothelial cells， and promoting angiogenesis. Furthermore， SMI can lower blood viscosity and lipid levels， thus improving blood rheology. In the future， more clinical trials and basic research are needed to clarify its therapeutic efficacy and target mechanism to further confirm the effectiveness and safety of its clinical application.
ABSTRACT
Objective:To explore the effectiveness of autologous fat grafting in the treatment of undesirable skin expansion.Methods:Patients' data were reviewed from 2011 to 2016, including the expanded regions with early signs of skin complications in face and neck. The effects of fat grafting group and control group were evaluated by follow-up records of expansion volume, skin thickness, skin texture and local capillary reaction.Results:Fat grafting could increase the thickness of expanded skin. It also improved the texture of expanded skin, with 0.83± 0.71 points before treatment and 1.30±0.66 points after treatment ( P=0.04). The local capillary reaction was also improved from 1.06±0.54 points before treatment and 1.45±0.51 points after treatment ( P=0.03). The expansion in the fat grafting group was 2.21±0.57 times before treatment and 2.94±0.83 times after treatment. In the control group, the expansion was 2.19 times when it showed early signs, and no obvious changes were observed during the follow-up period. Conclusions:Autologous fat grafting can effectively treat complications of skin expansion, prolong expansion process and promote tissue regeneration.
ABSTRACT
Objective@#The study aimed to explore the recommended treatment for toxicosis of botulism toxin type A.@*Methods@#From January 2016 to August 2017, 8 patients with toxicosis of botulism toxin type A were hospitalized in Shanghai Ninth People's Hospital, Shanghai Jiaotong University School of Medicine. All patients were female, 21-33 years of age, with an average age of 26.4 years. All patients showed progressive myasthenia and abnormal electromyography. The clinical manifestations and treatment outcomes of 8 patients in antitoxin group or non-antitoxin group were retrospectively analyzed. Five patients treated in plastic and reconstructive surgery department were included in the antitoxin group. They received skin test before injection, followed by intramuscular injection of 10 000-20 000 U antitoxins once a day for 2-3 days. Three patients treated in neurology department were included in the non-antitoxin group. They received only intravenous drip of neurotrophic drugs. After treatment, the improvement of clinical symptoms such as myasthenia and blepharoptosis was observed, and the electromyogram was followed up.@*Results@#The symptoms of myasthenia of the 5 patients in antitoxin treatment group were significantly improved, and the electromyogram signal returned to normal. However, for the 3 patients in non-antitoxin group, the symptoms of myasthenia did not significantly improve, and their electromyogram signal did not return to normal, even after 5 days′continuous treatment.@*Conclusions@#To regulate the cosmetic medical market is the key to prevent the accident of toxicosis of botulism toxin type A. It is necessary to make a definite diagnosis and medical intervene in time for the toxicosis. Antitoxin has a better curative effect, but further research is needed, to verify its safety and effectiveness.
ABSTRACT
Amniotic fluid embolism (AFE) is a clinical syndrome caused by amniotic fluid suddenly going into the maternal blood circulation in the process of delivery, the incidence is extremely low, however, its mortality is relatively high; since its clinical manifestations lack specificities, misdiagnosis or overlook of its presence often occurs. In this article, 1 case of delayed amniotic fluid embolism complicated with pituitary crisis leading to difficulty in weaning mechanical ventilation was reported in order to improve the understanding of AFE.
ABSTRACT
Objective To optimize the preparation technology ofCangai volatile oil dextrin inclusion compound/ in situ nasal thermosensitive gel by the central composite design-response surface method.Methods In the design, the investigation factors were the amounts of poloxamer 407 and poloxamer 188, and the evaluation index was the gel temperature. Quadratic models were used to evaluate the mathematic relation between the evaluation index and two investigation indexes to identify the optimum prescription, and then the optimum prescription was verified. Results According to the quadratic models, it was found that there was reliable quantitative relation between the evaluation index and two investigation indexes, among which the optimum dosage was 19.37% for poloxamer 407 and 2.73% for poloxamer 188.Conclusion The optimum model ofCangai volatile oil dextrin inclusion compound/ nasal thermosensitive gel can be obtained from central composite design-response surface method based on quadratic models. This method is reliable and feasible, which can realize the prescription optimization of the in situ gel.
ABSTRACT
Objective To analyze the clinical characteristics of dengue fever (DF) in Guangzhou Higher Education Mega Center (HEMC) in the year of 2014. Methods A retrospective analysis was carried out in the clinical data of 487 cases of DF patients. Results The incidence of DF accounted for 27.18% ( 527/1939) of the total emergeney fever cases. In 487 DF cases with detailed data, 261 were male, and 226 were female; 312 were young aged, 88 were middle aged, and 87 were old aged. For the systemic symptoms, fever accounted for 87.5%, headache 48.3%, and muscular soreness 47.6%. Cough ( 16.6%) , pharynx pain ( 16.8%) and running nose ( 10.9%) were common in respiratory symptoms; poor appetite ( 14.4%) and nausea ( 10.3%) were common in gastrointestinal symptoms. The abnormal laboratory parameters were mainly shown as WBC count ( 48.25%) and PLT count ( 41.68%) , following by creatine kinase ( CK, 39.49%) , aspartate aminotransferase ( AST, 34.12%) , and lactate dehydrogenase ( LDH, 31.96%) . Less cases had abnormal renal function. The distribution of Chinese medical syndrome types was shown as damp-heat blockage (65.7%), syndrome involving Weifen and Qifen simultaneously (23.6%), and Qi-yin deficiency (10.7%). Conclusion In the year of 2014, DF in Guangzhou HEMC occurred mainly among the youth people, the incidence of male DF was similar to that of the female DF, and DF cases usually have the primary symptoms of fever, aversion to cold, headache and muscular soreness. Bleeding is seldom seen in the DF patients, a few cases are complicated with the damage in the blood, liver and myocardium, and most of them have good prognosis.
ABSTRACT
Knowledge management, as a new managerial concept, is the specific embodiment of knowledge based economy in the field of management while technological innovation, constituting the core of technological progress, is the effective extension and application of scientific and technological knowledge. Hospitals, which are knowledge based institutions, possess good foundations and advantages of implementing knowledge management and technological innovation. There is a close link between knowledge management and technological innovation in hospitals, the former being the basis and primary guarantee of the latter and the latter being the result and manifestation of the former. Hospital managers should take measures to promote the sound interaction between the two so as to enhance the core competency of their hospitals.
