A simple and sensitive high performance liquid chromatography with fluorescence detection (HPLC–FD) has been developed for simultaneous quantification of doxorubicin (DOX) and its dipeptide conjugate prodrug (PDOX) in mice plasma. The chromatographic separation was carried out on an Amethyst C18–H column with gradient mobile phase of 0.1%formic acid and 0.1%formic acid in acetonitrile at a flow rate of 1.0 mL/min. The excitation and emission wavelengths were set at 490 and 550 nm, respectively. The method was comprehensively validated. The limits of detection were low up to 5.0 ng/mL for DOX and 25.0 ng/mL for PDOX. And the limits of quantification were low up to 12.5 ng/mL for DOX and 50 ng/mL for PDOX, which were lower than those for most of the current methods. The calibration curves showed good linearity (R2 4 0.999) over the concentration ranges. The extraction recoveries ranged from 84.0%to 88.2% for DOX and from 85.4% to 89.2% for PDOX. Satisfactory intra-day and inter-day precisions were achieved with RSDs less than 9.1%. The results show that the developed HPLC–FD method is accurate, reliable and will be helpful for preclinical pharmacokinetic study of DOX and PDOX.

Objective To assess the effectiveness of a novel mobile health patient management system involving doctors, nurses, and patients ( TRIO mode) on glycemic control and self-monitoring of blood glucose (SMBG) compliance among the type 2 diabetes mellitus ( T2DM) patients using basal insulin standardization treatment in China. Methods From April 2014 to April 2015, 416 hospitals in 110 cities of 30 provinces, municipalities, and autonomous regions across China were selected to participate in the program. A Online-to-Offline ( O2O) integrated mobile health patients management system with mobile terminals for the doctors, nurses, and patients was applied in the program for patient education, follow-up, and data collection. For all the newly recruited patients, the baseline information was collected and a first-day patient education program were provided by a designated nurse. In the 12-week follow-up period, data of basal insulin doses and fasting plasma glucose ( FPG) values were collected from the patients by text messages or tracking phone call by the nurse. The patients also received timely standardized patients health education and glycemic control guidance by participating in thepatient education forum anddoctors' hotline in order to help them achieve the glycemic control goals. Results A total of 102 524 patients using basal insulin treatment were eligible and enrolled in the program. 64 420 patients completed the 12 weeks follow-up and provided at least one FPG value at all five follow-ups. In total, 62. 6% (40 334 / 64 420) of the patients reached the FPG control target(FPG≤7. 0 mmol/ L) at the end of follow-up period. The weekly average FPG for patients with complete SMBG data decreased from 10. 58 mmol/ L to 6. 91 mmol/ L while the FPG control rates increased from 13. 4% to 69. 2% . The weekly average FPG for the patients provided incomplete SMBG data decreased from 10. 54 mmol/ L to 7. 13 mmol/ L while the FPG control rates increased from 13. 6% to 62. 2% . The FPG control rates for the patients provided complete SMBG were 1. 74 times higher than those patients provided incomplete SMBG. Based on a GEE model, the average decline of the FPG and the increase of the FPG control rates were significantly better for patients who provided complete SMBG as compared to the patients with incomplete SMBG data. The results of the multivariate logistic regression analysis showed that factors such as receiving the first-day education, participating in the follow-up patient education forum, and the doctors' hotline were significantly associated with the improvement of the SMBG compliance, the treatment adherence, and the FPG control rates. The SMBG compliance and the treatment adherence for patients who completed first-day education were 1. 68 times and 1. 22 times higher, respectively. For the patients who participated in follow-up education activities, their SMBG compliance and treatment adherence were 3. 17 times and 3. 36 times higher, respectively. Conclusion The innovativeTRIOmobile health patient management mode was feasible and effective for better managing the type 2 diabetes patients initiated on basal insulin treatment in China. Active participation in the first-day education program and the follow-up patient education activities can effectively improve the SMBG compliance and the treatment adherence, and therefore play an important role in helping patient achieving FPG control in a faster manner.

Objective:To investigate the efficacy and safety of nerve decompression surgery through the lateral-rectus approach for sacral plexus nerve injury after sacral fracture fixation.Methods:A retrospective study was conducted to analyze the 10 patients with combined sacral plexus nerve injury after sacral fracture fixation who had been admitted to Department of Orthopedics, Xiangya Hospital between May 2022 and May 2023. There were 2 males and 8 females with an age of 16.5 (15.0, 26.3) years. At the time of injury, the patients had been clearly diagnosed as sacral fracture combined with sacral plexus nerve injury. By the Denis classification of sacral fractures: 7 cases of type Ⅱ and 3 cases of type Ⅲ; sacral plexus nerve injury sites: 1 case of L 4, 8 cases of L 5, 7 cases of S 1, and 2 cases of S 2. All of them were treated with reduction and internal fixation via the posterior approach within 2 weeks after injury, but after surgery their manifestations of sacral plexus nerve injury still persisted which were confirmed by CT, magnetic resonance imaging and neuromuscular electromyography. Therefore, at (4.0±2.3) months after internal fixation, all patients were treated with nerve decompression surgery through the lateral-rectus approach. The operative time, intraoperative bleeding, length of hospitalization, Gibbons nerve damage score and neurological recovery at the last follow-up were recorded. Results:In the 10 patients, the operative time was (112.0±21.5) min, intraoperative bleeding (215.0±91.3) mL, and length of hospitalization 7.0 (6.0, 8.5) d. Intraoperatively, sacral plexus nerve compression was found in 9 cases (6 cases of nerve compression and pulling due to fracture displacement, 3 cases of nerve entrapment due to soft tissue scar adhesion), and 1 case of nerve root avulsion injury. No other intraoperative complications occurred. The 10 patients were followed up for (9.2±2.3) months after surgery. At the last follow-up, the Gibbons score for the 10 patients improved from preoperative 3.0 (3.0, 3.3) points to 1.0 (1.0, 2.0) point, and their British Medical Research Council (BMRC) nerve injury grading was improved from the preoperative grade 0.0 (0.0, 1.3) to grade 3.5 (2.8, 4.0) (1 case of M5, 4 cases of M4, 4 cases of M3, and 1 case of M2).Conclusion:The lateral-rectus approach is effective and safe for exploration and decompression of the sacral plexus nerve in patients combined with sacral plexus nerve injury despite sacral fracture fixation.

Objective To gain insights into the supportive care needs of liver transplant recipients,in order to provide references for the formulation of effective and targeted intervention strategies.Methods Phenomenological research method was employed to conduct semi-structural in-depth interviews with 16 liver transplant recipients in the liver transplant center of a tertiary hospital in Shanghai from November 2021 to April 2022.Colaizzi 7-step analysis method and Nvivo software were used to analyze and extract the themes.Results 5 themes were extracted,including symptom management needs,longing for the perception and avoidance of recurrence risk,disease information management needs,emotional and psychological support and the return to social roles.Conclusion The physical distress and burden of liver transplantation recipients coexist.Although the initiative to seek medical treatment is high,the perception level of disease recurrence risk is not high.In order to meet the needs of liver transplant recipients and improve their quality of life,it is necessary to strengthen the health education of disease symptom management and related risk factors,pay attention to psychological counseling and strengthen social support,and provide targeted treatment care.

Hepatic ischemia-reperfusion injury(HIRI) is a kind of liver injury caused by reperfusion after ischemic injury, which is clinically manifested by a series of deterioration phenomena such as liver function impairment, jaundice and even multi-organ failure after restoration of blood supply to the liver. HIRI seriously affects the patient's regression and prognosis. The essence of HIRI is a sterile inflammatory response. High mobility histone 1 (HMGB1) is an important intermediate mediator of HIRI and is a multiple cell type effector involved in HIRI. The receptor for glycosylated end products(RAGE) signaling axis of HMGB1 plays a key role in HIRI, but its mechanism is unclear. In this paper, the recent studies related to the pro-inflammatory mechanism of HMGB1-RAGE signaling axis in HIRI were summarized, and the relationship between HMGB1-RAGE signaling pathway and HIRI was discussed. The research progress of preventing and treating HIRI with surgical operation, ischemic preconditioning, drug and gene therapy using HMGB1-RAGE signaling axis as the target was reviewed.

Objective:To study the effectiveness of a strategy for detecting early gastric cancer using high-definition gastroscopy.Methods:A total of 849 patients over 35 years old who underwent gastroscopy in the Seventh Medical Center of PLA General Hospital from December 2018 to January 2019 were enrolled to a prospective study. During gastroscopy, biopsies were taken at any suspicious lesions in patients who had never been infected with Helicobacter pylori. In ulcer-type lesions, biopsies were taken at the edge of the ulcer. Outside the atrophic area, biopsies were taken at lesions in the cardia which were reddish under white light, or lesions in the non-cardiac area which were white or showed clear borders under white light. Inside the atrophic area, biopsies were taken at elevated lesions with clear borders or irregular depressions on the top, or flat/depressed lesions with irregular borders or being ocherous under narrow band imaging. In addition, biopsies were performed on any lesion that did not meet the above standard but was considered necessary. The high-risk patients were followed up by gastroscopy to observe the detection and missed diagnosis of neoplasm that meet the above standard, and to determine the sensitivity and positive predictive value of the strategy. Results:A total of 548 patients were biopsied (781 lesions). Among the 327 lesions that met the above standard, 16 lesions (4.9%) were diagnosed as epithelial neoplasm, of which 10 (3.1%) were high-grade neoplasm. Among the 454 lesions that did not meet the standard, only 1 (0.2%) epithelial neoplasm was diagnosed, and there was no high-grade neoplasm. The positive predictive value of this screening strategy for gastric epithelial neoplasm and high-grade neoplasm was higher than those who did not meet the standard (4.9% VS 0.2%, χ2=19.49, P<0.01; 3.1% VS 0, P<0.001). There were 146 patients (17.2%, 146/849) followed up by gastroscopy. During the follow-up, 2 high-grade intramucosal neoplasms were found. 84.2% (16/19) of epithelial tumors and 83.3% (10/12) of high-grade neoplasm were detected during the initial gastroscopy. Conclusion:This screening strategy can efficiently detect early gastric cancer under high-definition gastroscopy.

Objective:To explore the change in cerebral blood flow when healthy subjects swallow hot and ice water, and to verify the sensitivity of functional near-infrared spectroscopy (fNIRS) in identifying liquid temperatures while swallowing as a basis for applying it in diagnosis and intervention.Methods:Sixteen healthy subjects swallowed hot and ice water in randomized order while the process was recorded using fNIRS. The activation at rest and when swallowing hot and ice water was compared pairwise.Results:Compared with the resting state, 19 channels were activated during the swallowing of the hot and ice water. The common activated areas were S1, M1, PMC, SMA, Wernicke′s area, the somatosensory association cortex, the visual association cortex and the frontal eye field. However, the dorsal lateral prefrontal cortex was activated only when swallowing hot water, and the subcentral area was activated only when swallowing ice water. The SMA and PMC were significantly more activated when swallowing hot water than ice water.Conclusions:Multiple brain regions are activated and participate in regulating swallowing. The PMC and SMA areas can distinguish hot water from ice water swallowing.
