RESUMEN

Background: Within Diagnosis Related Groups, based on service capability, efficiency, and quality safety assessment, clinical pharmacists contribute to promoting rational drug utilisation in healthcare institutions. However, a deficiency of pharmacist involvement has been observed in the total parenteral nutrition support to patients following haematopoietic cell transplantation (HCT) within DRGs. Methods: This study involved 146 patients who underwent HCT at the Department of Haematology, the Second Affiliated Hospital of Dalian Medical University, spanning from January 2020 to December 2022. Results: Patients were allocated equally, with 73 in the control group and 73 in the pharmacist-involved group: baseline characteristics showed no statistics significance, including age, body mass index, nutrition risk screening-2002 score, liver and kidney function, etc. Albumin levels, prealbumin levels were significantly improved after a 7-day TPN support (34.92 ± 4.24 vs 36.25 ± 3.65, P = 0.044; 251.30 ± 95.72 vs 284.73 ± 83.15, P = 0.026). The body weight was increased after a 7-day support and before discharge (58.77 ± 12.47 vs 63.82 ± 11.70, P = 0.013; 57.61 ± 11.85 vs 64.92 ± 11.71, P < 0.001). The length of hospital stay, costs and the rate of re-admissions were significantly shortened (51.10 ± 1.42 vs 46.41 ± 1.86, P = 0.048; 360,162.67 ± 91,831.34 vs 324,070.16 ± 112,315.51, P = 0.035; 61.64% vs 43.84%, P = 0.046). Conclusions: Pharmacist-joint TPN support enhances the service efficiency score of medical units, ensuring the fulfilment of orders and rational medication.

RESUMEN

In order to decrease the toxicity of paclitaxel (PTX) and increase the efficiency, we developed an amphiphilic PTX injection system using a biodegradable and biocompatible polymer synthesized by folic acid, cholesterol, and chitosan (FACC). This FACC-based polymer had a low critical concentration (64.13µg/ml) and could self-assemble in aqueous condition to form nanoscale micelles. The particle sizes of FACC-PTX micelles were 253.2±0.56 nm, the encapsulation efficiency and loading capacity of these FACC-PTX micelles were 65.1±0.23% and 9.1±0.16%, respectively. The cumulative release rate was about 85% at pH 5.0 which was higher than that at pH 7.4 (76%). This pH-dependent release behavior was highly suggesting that PTX release from FACC-PTX micelles might be higher in a weak acidic tumor microenvironment and lower toxic for normal cells. The anti-cancer effectiveness of FACC-PTX micelles was investigated by in vitro cytotoxicity and targeting study. The results revealed that FACC micelles have non-toxic on cells as evidenced by high cell viability found (86% to 100%) in the cells cultured with various concentrations of FACC micelles (1 to 500 µg/ml). Targeting study indicated that the cytotoxic efficacy of FACC-PTX micelles was significantly higher than that with Taxol® in the Hela cells (folate receptor-positive cells). These findings indicated that the anticancer efficiency of PTX can be enhanced by adding some cancer cell positive receptor into drug carrier and the FACC micelle was a potential tumor targeting carrier for PXT delivery.

RESUMEN

OBJECTIVE: To develop a risk scoring model for screening for undiagnosed type 2 diabetes in Chinese population. METHODS: A total of 5348 subjects from two districts of Jinan City, Shandong Province, China were enrolled. Group A (2985) included individuals from east of the city and Group B (2363) from west of the city. Screening questionnaires and a standard oral glucose tolerance test (OGTT) were completed by all subjects. Based on the stepwise logistic regression analysis of Group A, variables were selected to establish the risk scoring model. The validity and effectiveness of this model were evaluated in Group B. RESULTS: Based on stepwise logistic regression analysis performed with data of Group A, variables including age, body mass index (BMI), waist-to-hip ratio (WHR), systolic pressure, diastolic pressure, heart rate, family history of diabetes, and history of high glucose were accepted into the risk scoring model. The risk for having diabetes increased along with aggregate scores. When Youden index was closest to 1, the optimal cutoff value was set up at 51. At this point, the diabetes risk scoring model could identify diabetes patients with a sensitivity of 83.3% and a specificity of 66.5%, making the positive predictive value 12.83% and negative predictive value 98.53%. We compared our model with the Finnish and Danish model and concluded that our model has superior validity in Chinese population. CONCLUSIONS: Our diabetes risk scoring model has satisfactory sensitivity and specificity for identifying undiagnosed diabetes in our population, which might be a simple and practical tool suitable for massive diabetes screening.

RESUMEN

OBJECTIVE: To investigate the relationship between coxsackievirus infection and type 1 diabetes mellitus (T1DM), and observe the changes of T lymphocyte subsets in the development of T1DM. METHODS: We detected Coxsackievirus RNA by reverse transcription PCR, and measured the change in T-lymphocyte subsets by flow cytometry in 22 cases of newly diagnosed T1DM (group I), 30 patients with diabetes for some time (group II), and 30 healthy subjects (group III). RESULTS: The positivity rate of coxsackie virus RNA in groups I, II, and III was 55.55%, 23.33%, and 6.67%, respectively, showing a significant difference among the 3 groups (P<0.01). Patients with upper respiratory tract infection had a higher positivity rate for coxsackie virus RNA than those without upper respiratory tract infection in group I (P<0.05). Compared with the control group, the percentage of CD3, CD4 and CD4/CD8 ratio decreased significantly in groups I and II (P<0.01 or P<0.05). CD3, CD4 and CD4/CD8 tended to increase in group II in comparison with group I, and there was an significant difference in CD3 and CD4 between the two groups (P<0.01 or P<0.05). Compared with the control group and CVBRNA-negative group, CVBRNA-positive group showed significantly lowered CD3, CD4, CD8 and CD4/CD8 (P<0.01 or P<0.05). CONCLUSION: The occurrence and development of type 1 diabetes is closely related to coxsackie virus infection, and the changes in T lymphocyte subsets serves as a probable mechanism of its pathogenicity.

RESUMEN

BACKGROUND: Few studies have given suggestions on appropriate initiation insulin dosage when combined with oral antidiabetic drugs (OADs). This research was to investigate appropriate initiation insulin doses for insulin-naive type 2 diabetes patients with different combinations and the relationship between insulin dosage and relevant factors. METHODS: This was a randomized, open-label, treat to target study. The target was 20% decrease of both fasting plasma glucose (FPG) and 2 hours post-breakfast blood glucose (P2hBG). One hundred and forty-seven insulin-naive Chinese patients recruited were randomly assigned to 3 groups: group A, patients received insulin monotherapy; group B, received insulin plus metformin (0.5 g, tid) and group C, received insulin plus metformin (0.5 g, tid) and pioglitazone (15 mg, qd). Insulin doses were initiated with a dose of 0.3 U×kg(-1)×d(-1) and titrated according to FPG and P2hBG till reached the targets. RESULTS: Both the time of getting 20% reduction of FPG and P2hBG showed significant differences among the three groups. The time was shortest in Group C. The insulin doses needed to achieve glucose reduction of 20% in three treatment groups were (0.40 ± 0.04) U×kg(-1)×d(-1) for Group A, (0.37 ± 0.04) U×kg(-1)×d(-1) for Group B, and (0.35 ± 0.03) U×kg(-1)×d(-1) for Group C, respectively. Multiple linear stepwise regression analysis showed that insulin doses correlated with body weight, FPG, diabetes duration, age and history of sulfonylurea treatment. The standardized regression coefficients were 0.871, 0.322, 0.089, 0.067 and 0.063 (with all P < 0.05). CONCLUSIONS: To achieve blood glucose's reduction of 20% within safety context, initial insulin doses were recommended as the following: 0.40 U×kg(-1)×d(-1) for insulin mono-therapy, 0.37 U×kg(-1)×d(-1) for insulin plus metformin treatment, and 0.35 U×kg(-1)×d(-1) for insulin plus metformin and pioglitazone treatment in Chinese type 2 diabetes outpatients. Body weight is found the most closely related factor to the insulin dosage.

RESUMEN

Salvia plebeia R. Br is a traditional Chinese herb which has been considered as an inflammatory mediator used for treatment of many infectious diseases including hepatitis. Previously, the compound homoplantaginin was isolated in our group. Hence, we evaluated the protective effects of homoplantaginin on hepatocyte injury. Homoplantaginin displayed an antioxidant property in a cell-free system and showed IC(50) of reduction level of DPPH radical at 0.35 microg/ml. In human hepatocyte HL-7702 cells exposed to H(2)O(2), the addition of 0.1-100 microg/ml of homoplantaginin, which did not have a toxic effect on cell viability, significantly reduced lactate dehydrogenase (LDH) leakage, and increased glutathione (GSH), glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) in supernatant. In vivo assay, we employed the model of Bacillus Calmette-Guérin (BCG)/lipopolysaccharide (LPS)-induced hepatic injury mice to evaluate efficacy of homoplantaginin. Homoplantaginin (25-100mg/kg) significantly reduced the increase in serum alanine aminotranseferase (ALT) and aspartate aminotransferase (AST), decreased the levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 (IL-1). The same treatment also reduced the content of thiobarbituric acid-reactive substances (TBARS), elevated the levels of GSH, GSH-Px and SOD in hepatic homogenate. The histopathological analysis showed that the grade of liver injury was ameliorated with reduction of inflammatory cells and necrosis of liver cells in homoplantaginin treatment mice. These results suggest that homoplantaginin has a protective and therapeutic effect on hepatocyte injury, which might be associated with its antioxidant properties.
