Serum Cardiac troponin Ⅰ (cTn Ⅰ) and lactic acid were measured in 128 neonatal patients with hypoxic-ischemic encephalopathy and 38 healthy neonates (control group). Serum cTn Ⅰ and lactic acid levels were higher in neonates with hypoxic-ischemic encephalopathy than those in healthy neonates (P < 0. 05 ); and the differences of these values were also statistically significant between the serious patients and the mild patients (P<0.05). Serum cTn Ⅰ and lactic acid are two sensitive markers for degree of myocardial injury and hypoxia in neonatal patients with hypoxic-ischemic encephalopathy.

OBJECTIVE:To explore the necessity of developing therapeutic drug monitoring of vancomycin in our hospital and its existing problems,and provide a reasonable basis for the clinical rational use of vancomycin. METHODS:The cross-sectional survey was designed to collect the clinical data of 92 patients with therapeutic drug monitoring of vancomycin and statistically ana-lyze 192 cases of plasma concentration monitoring data. RESULTS:The average plasma trough concentration was (15.96 ± 8.06) mg/L;with the increase of age,the plasma trough concentration was increasing,there was no significant difference in the plasma trough concentration among different age groups (P=0.000);there were only 13 cases (6.77%) that obtained the plasma trough concentration within 30 min before the fourth dose;after using wancomycin,clearance rates of Cr and the endogenous creatinine were slightly higher than before,but there was no significant difference(P=0.722);36 cases(39.13%)showed vancomycin sus-ceptible gram positive cocci;after using wancomycin,the body temperature,white blood cell count and neutrophil percentage were lower than before,the differences were statistically significant (P=0.006,P=0.000,P=0.000);48 cases (52.17%) in treatment received initial loading dose,and only 15 cases (16.30%) did not use in combination with other anti infective drugs. CONCLU-SIONS:The results showed there are still a lot of problems in the treatment of vancomycin in our hospital,for example,the stan-dard rate of the plasma trough concentration is about 50%;most of the time of blood sampling is not reasonable;the detection rate of the pathogen is low;only about half of the cases are given the loading dose,etc. Therefore clinical pharmacists’intervention for blood sampling is an important part to promote rational drug therapy monitoring. Meanwhile,data interpretation of the monitoring results of serum drug concentration of vancomycin is a basic method for clinical pharmacists in clinical monitoring to correct the un-reasonable operations,and also the necessary measures for preventing the drug renal toxicity,it is a very important significance for the medication safety and effectiveness especially in severe infection patients,the elderly,the children and the people with renal function insufficiency.

OBJECTIVE: To construct short hairpin RNA interfering expression vector of TDRG1,and detect the specific interfering effect of TDRG1-shRNA expression vector on NTERA-2 cells. METHODS: Oligos for short hairpin RNA targefing for TDRG1 were designed and connected to the expression vector pGPU6/GFP/Neo to construct the TDRG1 shRNA expression vector. The recombinant plasmid TDRG1-shRNA486, TDRG1-shRNA738, TDRG1-shRNA921 and lipofectamine ™2000 were used to generate and transfect shRNA into NTERA-2 cells. Expression of TDRG1 mRNA was assayed by RT-PCR. RESULTS: TDRG1-shRNA expression vector was successfully constructed. TDRG1-shRNA486 was more effective in the suppression of TDRG1 with significant reduction of TDRG1 mRNA. CONCLUSION TDRG1-shRNA can interfere the expression of TDRG1 in NTERA-2 cells.

Objective To investigate the application and effect of bundle nursing intervention combining with ventilator pipeline disinfection in the prevention of ventilator-associated pneumonia (VAP). Methods A total of 100 cases who had not received bundle nursing intervention combining with ventilator pipeline disinfection in ICU ward,Cangzhou Central Hospital between February 2012 to January 2014 were treated as control group,while another 100 cases who had received bundle nursing intervention combining with ventilator pipeline disinfection in the same ward from February 2014 to January 2016 were treated as observation group. Incidence of VAP,length of mechanical ventilation time and ICU stay of two groups were compared. Results In different models of nursing care,incidence rate of VAP of the observation group and the control group were 9.0% and 24.0%(χ2=3.52,P < 0.05);length of mechanical ventilation time and ICU stay of the observation group were (4.62±2.10) d and (7.30±1.30) d which were shorter than those of the control group (t=2.40,19.30;P < 0.05). Conclusions Bundle nursing intervention combining with ventilator pipeline disinfection could lower the incidence of VAP,shorten the duration of mechanical ventilation time,ICU stay and improve patients' satisfication which is worthy of application in clinic.

Objective To investigate the level and its influencing factors of quality of life for burn patients undergoing amputation,and take treatment measures for clinical nursing. Methods The single factor analysis method was taken on the burn patients undergoing amputation in different social demographic characteristics from January 2013 to July 2016.

OBJECTIVE To provide a reference for the dose adjustment of tacrolimus in patients who underwent lung transplantation after combined use of voriconazole. METHODS The clinical data of lung transplantation patients who used voriconazole and tacrolimus in our hospital from January 2020 to December 2022 were collected retrospectively. The effects of voriconazole on the valley concentration， daily dose and standardized blood concentration of tacrolimus were analyzed by using SPSS 21.0 software； multiple linear regression analysis was conducted for the factors that may affect the standardized blood concentration of tacrolimus. RESULTS A total of 153 lung transplantation patients were included. After the combination of voriconazole， the average daily dose of tacrolimus decreased from 3.37 mg to 0.76 mg， and valley concentration and standardized blood concentration were increased significantly （P＜0.000 1）. The average daily dose of voriconazole was negatively correlated with the standardized blood drug concentration of tacrolimus （P＝0.000 1，r＝－0.224）. The valley concentration of voriconazole was positively correlated with valley concentration （P＜0.000 1，r＝0.316） and standardized blood concentration （P＜0.000 1，r＝ 0.249） of tacrolimus. After combination with voriconazole， the standardized blood drug concentration of patients who underwent single lung transplantation was significantly higher than those who underwent double lung transplantation， and the standardized blood concentration of tacrolimus after oral administration of voriconazole was significantly higher than after intravenous drip of voriconazole （P＜0.05）. Most liver and kidney function indicators showed no significant changes. The results of multiple factor regression analysis showed that the valley concentration of voriconazole had a significant impact on the standardized blood concentration of tacrolimus （P＜0.001）. CONCLUSIONS The valley concentration of voriconazole has greatest influence on the blood concentration and dose adjustment of tacrolimus， which is an independent influencing factor. In clinical practice， the dose of tacrolimus should be reduced in combination with voriconazole， and therapeutic drug monitoring should be conducted for both drugs.

Skin ulcers are the most prevalent consequence of diabetes mellitus, and people with diabetic ulcers have a substantially greater death risk than those who do not have ulcers. Herbal medications have gained wide concern in recent years due to their multi-component, multi-target, and multi-pathway synergistic therapeutic effects. Clinical trials have demonstrated the safety and efficacy of herbal treatments in diabetic refractory ulcers. To systematically evaluate the healing effect of herbs on diabetic wounds, a literature search was conducted, the mechanism of action of 15 herbal extracts in promoting diabetic wound healing were reviewed, and the classification based on traditional Chinese medicine theory was discussed, which could provide a reference for the precise treatment and exploitation of herbal medicines for diabetic ulcers.
