Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

Objective:To investigate the detection rate of motoric cognitive risk(MCR)syndrome and explore the possible risk factors at different age groups.Methods:A total of 561 patients from geriatric outpatient clinic of Hubei Provincial Hospital of Traditional Chinese Medicine from November 2018 to December 2019 were divided into two age groups under 70 years old(n=241)and 70 years old and above(n=320). The general information, Pittsburgh Sleep Quality Index, Geriatric Depression Scale-15(GDS-15), 4-meter walking test, Mini-Mental State Examination and Morse Fall Scale were collected.Patients with MCR were screened out according to the MCR diagnostic criteria.Logistic multiple regression analysis was used to analyze the associated risk factors.Results:7 cases(7/241, 2.9%)met the MCR diagnostic criteria in age<70 years group, and 34 cases(34/320, 10.7%)in age ≥ 70 years group.The proportion of hearing impairment complaints and GDS-15 scores of MCR patients were higher than those of the non-MCR group in age<70 years group, and the Morse Fall Scale of MCR patients was higher than that of the non-MCR group in age ≥70 years old group( P<0.05). After adjusting for associated confounding factors, multiple logistic regression analysis showed that hearing impairment complaints( OR=26.394, P<0.05)and GDS-15( OR=1.385, P<0.05)were independent risk factors for MCR in age<70 years group.And female( OR=0.445, P<0.05)was a protective factor for MCR in age ≥70 years old group. Conclusions:Motoric cognitive risk syndrome has different risk factors in different age groups, which may indicate that the causes and predictive significance of MCR in these two different age groups are different.

Objective The dynamic detection of endotoxin is of great significance for the early diagnosis and treatment of prosthesis loosening after joint replacement. This study aimed to explore and analyze the clinical significance and efficacy of endotoxin detection in prosthetic joint loosening after joint replacement.Methods Fifty-eight patients who underwent arthroplasty in the department of orthopedics in Nanjing General Hospital from January 2015 to June 2016 were selected for prospective study. The patients were divided into the infection loosening group (patients with infectious loosening after arthroplasty, n=15), the aseptic loosening group (patients with aseptic loosening of after arthroplasty, n=23) and the control group (patients were normal after arthroplasty, n=20) according to the postoperative complications. Endotoxin was detected with MB-80 microbial dynamic rapid detection system. We compared the endotoxin level and the ROC curve was made to acquire the sensitivity and specificity under the different cut-off values. Eventually find the best diagnostic threshold.Results The levels of endotoxin in the infection loosening group and the aseptic loosening group \[(0.56±0.11, 0.49±0.08) ng/mL\] were significantly higher than that in the control group \[(0.24±0.06) ng/mL\]. The difference was statistically significant (P<0.01). The difference was not statistically significant between the infection loosening group and the sterile loosening group (P>0.05). ROC curve analysis showed that when the serum endotoxin concentration was 0.36 ng/mL, the Youden index was the highest, which could be the best cut-off value for diagnosis. It had the best accuracy to judge the prosthesis loosening with a sensitivity of 66.7% and specificity of 88.2%.Conclusion The endotoxin can be a good indicator for early diagnosis of prosthesis looseness. It is helpful to the diagnosis of the prosthesis loosening after arthroplasty.

Objective To investigate the performance of MicroScan WalkAway 96 Plus (MSW) system in detection of carbapenem-resistant Enterobacteriaceae (CRE).Methods A total of 81 stock CRE strains were used in this study. Bacterial identification and antimicrobial susceptibility test were performed by MSW system. Beta-lactamases genes blaKPC,blaIMP,blaVIM, blaOXA-48 and blaNDM were amplified by PCR and subjected to sequencing analysis. Disk diffusion method and PCR were used as gold standard to evaluate the performance and reliability of MSW system in identifying carbapenem-resistant and carbapenemase-producing Enterobacteriaceae.Results Overall, 69.1 % (56/81) of the Enterobacteriaceae strains were identified as CRE by the MSW system. The results of PCR showed that 48 strains were carbapenemase-producing Enterobacteriaceae. When carbapenemase-producing Enterobacteriaceae strains were identified by the instrument using an advanced expert system, the sensitivity was 93.8 % and specificity was 42.4 %. The positive predictive value was 70.3 %, the negative predictive value was 82.4 % and the predictive accuracy value was 72.8 %.Conclusions The MicroScan WalkAway 96 Plus system has shown good performance in detection of CRE.

OBJECTIVE:To observe clinical efficacy and safety of exenatide combined with clomiphene citrate in the treatment of polycystic ovary syndrome with insulin resistance. METHODS:98 patients with polycystic ovary syndrome complicated with in-sulin resistance were randomly divided into control group (49 cases) and observation group (49 cases). Control group was given Clomiphene citrate capsule 50 mg orally,once a day,for 5 d+Metformin enteric-coated tablet with initial dose of 0.25 g orally, twice a day,adjusted to 0.50-0.75 g orally,twice a day,for 3 menstrual cycles. Observation group was given Clomiphene citrate capsule(usage and dosage same as control group)+Exenatide injection 5 μg subcutaneously,twice a day,adjusted to 10 μg subcu-taneously,twice a day,for 2 months. Clinical efficacies of 2 groups were observed as well as the levels of LH,FSH,LH/FSH and IR before and after treatment,ovulation and pregnancy of infertility patients after treatment. The occurrence of ADR was record-ed. RESULTS:Total response rate,ovulation rate and pregnancy rate of observation group were significantly higher than that of con-trol group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in the levels of LH,FSH, LH/FSH and IR between 2 groups (P>0.05). After treatment,the levels of LH,LH/FSH and IR in 2 groups were significantly lower than before,and the observation group was significantly lower than the control group,the levels of FSH in 2 groups was sig-nificantly higher than before,and the observation group was significantly higher than the control group,with statistical significance (P<0.05). There was no statistical significance in incidence of ADR between 2 groups(P>0.05). CONCUSIONS:Exenatide com-bined with clomiphene citrate shows significant therapeutic efficacy for polycystic ovary syndrome complicated with insulin resis-tance and can increase ovulation rate and pregnancy rate through improving insulin resistance,but doesn't increase the occurrence of ADR.

Pulmonary drug delivery has become a research focus in recent years, while the action between particles and pulmonary macrophages after particles transportation to lung tissue was paid little attention. Therapeutic efficacy can be enhanced by regulating the particles uptake action of pulmonary macrophages according to different diseases. Referring to a lot of articles, the relationship between common diseases and macrophages was reviewed and the influencing factors in the particles uptake of alveolar macrophages were sum-marized. The review laid foundation for the development of preparations and clinical application of pulmonary drug delivery systems.

Objective: The therapeutic effect of acid fibroblast growth factor 1(FGF1) on rats with diabetic cardiomyopathy (DCM) was evaluated by using nano-liposomes combined with ultrasound-targeted microbubble destruction technique (UTMD). Methods: The FGF1-loaded nano-liposomes were prepared by water-in-water emulsion method combined with lyophilization technique.TypeⅠdiabetes model was induced by intraperitoneal injection of streptozotocin (STZ, 70 mg/kg) in 60 male SD rats.Sixteen weeks later, diabetic rats were randomly divided into: placebo group (saline treatment), FGF1 group, FGF1-loaded nano-liposomes group, and FGF1-loaded nano-liposomes plus UTMD group (n=15 each). After two weeks of intervention followed by 2 weeks intervention stop, all rats underwent cardiac catheterization, and the left ventricular end-systolic pressure (LVESP), left ventricular end-diastolic pressure (LVEDP) and the maximal increase/decrease rate of left ventricular pressure (LV±dp/dtmax) were measured.Then, the rats were sacrificed and myocardial tissue were obtained for Masson trichrome staining, TUNEL apoptotic staining and CD31 immunohistochemistry staining to quantify myocardial collagen fraction (CVF), cardiac myocyte apoptotic index and myocardial microvascular density (MVD). Results: (1)Scanning electron microscope results revealed good morphology and FGF1 encapsulation efficiency (84.3±2.8)% with high stability and dispensability of FGF1 loaded nano-liposomes.(2)The hemodynamic evaluation showed that LVESP, LV + dp/dt_max and LV -dp/dt_max were all significantly higher, while LVEDP was significantly lower in the FGF1-loaded nano-liposome+ UTMD group than in DCM group, FGF1 solution group, and FGF1 nano-liposome group(all P<0.05). (3)The Masson trichrome staining demonstrated that CVF was significantly higher in all DCM groups than in control group and was significantly lower in the FGF1-loaded nano-liposome+ UTMD group than in DCM group, FGF1 solution group, and FGF1 nano-liposome group (all P<0.05). (4)The CD31 immunohistochemical staining results showed that MVD was significantly lower in all DCM groups than in control group and was significantly higher in the FGF1-loaded nano-liposome+ UTMD group than in DCM group, FGF1 solution group, and FGF1 nano-liposome group (all P<0.05). (5)The TUNEL results showed that apoptotic index was significantly higher in all DCM groups than in control group and was significantly lower in the FGF1-loaded nano-liposome + UTMD group than in DCM group, FGF1 solution group, and FGF1 nano-liposome group (all P<0.05). Conclusion FGF1 nano-liposomes combining with UTMD technique can significantly improve cardiac functions and attenuate myocardial CVF and apoptosis and enhance myocardial MVD in DCM rats.

Curcumin is the main active component in turmeric, which possesses many pharmacologic effects, including anti-in-flammatory, antioxidant, anti-tumor, anti-atherosclerosis, liver and kidney protection and so on. However, due to its poor bioavail-ability, its clinical application is limited. Therefore, the methods for improving the bioavailability of curcumin were reviewed by refer-ring to a large number of literatures. The bioavailability of curcumin can be improved by different administration routes and various dos-age forms. The review provides theoretical basis and research ideas for the development of new drugs.
