Objective:To evaluate the skin development and repair process of X-ray radiation damage in rat with non-invasive two-photon excitation fluorescence (TPEF) imaging technology in vivo. Methods:Totally 24 SD rats were randomly divided into four groups including X-ray irradiated group (25, 35 and 45 Gy) and non-irradiation control group. At different times after irradiation, the degree of skin injury was evaluated, and the pathological changes of nicotinamide adenine dinucleotide (phosphate) [NAD(P)H] and collagen fiber fluorescence signals in epidermal cells were detected in vivo by TPEF imaging technology. Results:At 10 d post-irradiation, the skin of irradiation groups showed erythema and desquamation. At 15-20 d post-irradiation, the skin of radiation groups developed progressive exudation, edema and ulcers with increasing radiation dose. On day 25, the skin began to repair in the 25 Gy group, however, the skin of other groups still had exudation and ulcers. On day 10, NAD(P)H fluorescence signal in epidermal cells of irradiation groups decreased and the fluorescence signal of collagen fibers in papillary layer and reticular layer of irradiation groups reduced, which were significantly lower than that of normal control group ( t=24.145, 28.303, 26.989, 6.654, 7.510, 7.997, P<0.05). On day 30, fluorescence signal of NAD(P)H and collagen fibers in epidermal cells and dermis began to repair, the cell from stratum granulosum, stratum spinosum, and stratum basale in the 25 Gy group showed fluorescence signal, the other groups did not show. The fluorescence signal of collagen fibers in the 25 Gy group were gradually increased in papillary layer and reticular layer, however, they were significantly lower than normal control group ( t=115.133, 17.431, P<0.05), the skin of 45 Gy group did not show fluorescence signal of collagen fibers. Conclusions:The damage and repair process of epidermal cells and dermal collagen fiber can be detected noninvasively by TPEF imaging technology after X-ray irradiation in vivo.

OBJECTIVE To explore the application effects of the multi-disciplinary treatment (MDT)-based continuous pharmaceutical care system in patients undergoing anti-infection treatment. METHODS This research team innovatively developed an MDT continuous pharmaceutical care system, which was applied to cases of anti-infection treatment following MDT due to infection, aiming to innovate the continuous medication supervision model. A retrospective analysis method was used to collect data from 150 patients in the intensive care unit who underwent conventional anti-infection MDT consultations from January to October 2021 in Banan Hospital Affiliated to Chongqing Medical University, serving as the control group, and 130 patients in the intensive care unit who were under the MDT continuous pharmaceutical care system from January to October 2022 were selected as the intervention group. The general information of the patients, the information continuous tracking management, the outcomes of anti- infection treatment, adverse drug reactions, antibacterial drug management indicators, and the degree of satisfaction of relevant medical staff with the clinical pharmacists’ pharmaceutical services were compared between the two groups. RESULTS Comparison of general information between the two groups showed no statistically significant differences (P>0.05). The proportion of continuous tracking management in the intervention group was significantly higher than in the control group (P<0.01), and the differences in the initiators and reasons for continuous tracking management between the two groups were statistically significant (P<0.05). The intervention group had better outcomes in anti-infection treatment compared to the control group (P<0.05). The antibacterial drug management indicators (total length of hospital stay, duration of antibacterial drug use, total drug costs, and amount of antibacterial drugs used) in the intervention group were significantly lower than in the control group, while overall degree of satisfaction among medical staff was significantly higher in the intervention group than in the control group (P<0.05). No statistically significant differences were found in adverse reaction occurrence and antibacterial drug costs between the two groups (P>0.05). CONCLUSIONS The application of this system in patients who underwent anti-infection treatment after MDT can achieve continuous multi-disciplinary tracking management with clinical pharmacists at the core, which is beneficial for promoting the follow-up efficiency of the MDT team, raising the quality of clinical pharmacists’ pharmaceutical services, strengthening treatment outcomes, and promoting the rational use of antibacterial drugs in clinical practice.

OBJE CTIVE To investigate the clinical characteristics of a dverse drug reactions of asparaginase-associated pancreatitis(AAP),so as to provide reference for clinical safe medication. METHODS Analysis and identification were performed on a severe adverse reaction case of acute pancreatitis complicated with diabetic ketoacidosis and liver injury in a patient with acute lymphoblastic leukemia in our hospital after using pegaspargase. Retrieved from Wanfang database ,CNKI,PubMed and Embase database,case reports of AAP were collected and summarized in terms of patient demographics ,drug use ,incubation period and adverse reaction outcome. Combined with this case ,the disease characteristics and potential risk factors of AAP were analyzed and discussed. RESULTS After analysis and identification ,it was determined that AAP occurred in this patient. A total of 47 case reports were retrieved from the database ,and a total of 52 patients(including this patient )were included in the analysis ,including 29 males and 23 females,mainly minors (65.4%). L-asparaginase was the main asparaginase preparation that causes AAP (80.8%). Gastrointestinal symptoms were the main prodromal symptoms (92.3%),which could be accompanied by other asparaginase related adverse reactions. AAP could occur after 1-33 times of administration ,and the median latency was 14 days after administration;compared with children ,median latency of AAP in adult patients was shortened significantly (11 d vs. 16 d,P= 0.049);the median latency of AAP had longer tendency in patients treated with pegaspargase than that of L-asparaginase (17 d vs. 12.5 d,P=0.490). Of the cases included in the analysis ,8 patients died due to AAP ,1 of which was related to re-exposure to asparaginase preparations. CONCLUSIONS Acute pancreatitis is a serious and potentially fatal adverse drug reaction of ; asparaginase preparations. Clinical medical staff should pay attention to the characteristics of AAP ,consider the possibility : of AAP when the patients have gastrointestinal symptoms and do a good job in patient education and pharmaceutical care to minimize the damage caused by AAP to patients.

Pharmacy active consultation refers to the spontaneous activity that clinical pharmacists take the initiative to go to clinical departments to help doctors solve problems related to drug use in clinical practice ,put forward drug treatment suggestions or provide pharmaceutical services ,and form medical documents . The difference between pharmacy active consultation and pharmacy consultation is that the latter is generally proposed by the clinician ,who sends a consultation invitation to the pharmacy department in the hospital information system ,and the clinical pharmacist will go to the consultation after receiving it ,while the former is a pharmaceutical service mode that the clinical pharmacist takes the initiative to carry out in the clinical department . On the basis of routine pharmacy active consultation ,clinical pharmacists in our hospital also further carried out a special active consultation mode (including prompt special active consultation for patients with multidrug resistance bacteria positive ,active monitoring and intervention for patients with drug -induced liver injury ),and patient pharmaceutical supervision in the form of return visit of pharmacy active consultation . Pharmacy active consultation and its special active consultation possess the characteristics of initiative , early and extensive coverage ,as a supplement to resident clinical pharmacy services . Pharmacy active consultation could help the pharmacy department to improve service efficiency ,provide a new perspective for medical institutions to carry out efficient pharmaceutical services ,and supply new ideas for the reform of pharmaceutical services in China .
