The promulgation of the Technical Specifications for Clinical Use of Blood (2025 Edition) signifies that China's clinical blood transfusion management has transitioned from mere technical operations to a new stage centered on patient blood management (PBM). Through an in-depth comparison of the new and old specifications, this paper analyzes the core transformations regarding conceptual reconstruction, legal alignment, technological upgrades, and closed-loop management. The new specifications establish PBM principles, reinforce legal safeguards for informed consent and emergency treatment, and construct a comprehensive, refined quality control system by specifying compatibility testing standards and introducing a post-transfusion evaluation system. Medical institutions should seize this opportunity to update management protocols and information systems, deepen multidisciplinary collaboration, and drive the profound transformation of clinical blood use from focusing solely on safety assurance to placing equal emphasis on science and value.

Objective:To compare the clinical efficacy of endoscopic posterior transforaminal lumbar interbody fusion (Endo-PTLIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in the treatment of single-segment lumbar degenerative diseases.Methods:A retrospective analysis was conducted on the clinical data of 56 patients with single-segment lumbar degenerative diseases treated at Xiuzhou District People's Hospital between September 2020 and March 2023. Patients were divided into two groups based on the surgical approach: the Endo-PTLIF group (24 cases, 11 males and 13 females; mean age: 56.5±8.4 years, range: 43-72 years) and the MIS-TLIF group (32 cases, 10 males and 22 females; mean age: 54.5±10.4 years, range: 37-73 years). Perioperative parameters, visual analog scale (VAS) scores for pain, Oswestry disability index (ODI), lumbar lordosis (LL), disc height (DH), and dural sac cross-sectional area (DSCA) were compared between the two groups.Results:No significant differences were observed between the two groups in baseline characteristics, preoperative VAS, ODI, LL, DH, or DSCA ( P>0.05). However, the operative time in the Endo-PTLIF group (173.9±12.3 minutes) was significantly longer than in the MIS-TLIF group (136.5±19.5 minutes, P<0.05). Similarly, the Endo-PTLIF group required more fluoroscopy exposures (15.9±1.8) than the MIS-TLIF group (13.0±1.6, P<0.05). In contrast, intraoperative blood loss in the Endo-PTLIF group (68.9± 12.9 ml) was significantly lower than in the MIS-TLIF group (126.7±35.4 ml, P<0.05). Additionally, the Endo-PTLIF group had a shorter hospital stay [7.00 (6.25, 7.75) days] compared to the MIS-TLIF group [10.00 (9.25, 11.00) days, P<0.05]. At one week and one month postoperatively, the Endo-PTLIF group had significantly lower back pain VAS scores [2.00 (2.00, 3.00) and 2.00 (2.00, 2.00), respectively] and a lower ODI (25.83%±3.83%) compared to the MIS-TLIF group [3.00 (2.25, 4.00), 2.50 (2.00, 3.00), and 30.09%±4.02%, respectively; P<0.05]. Beyond one month postoperatively, there were no significant differences in leg pain VAS scores between the groups, and back pain VAS and ODI showed no significant differences after six months ( P>0.05). At the final follow-up, the excellent and good rates, according to MacNab criteria, were 95.8% in the Endo-PTLIF group and 93.8% in the MIS-TLIF group, with no significant difference ( P>0.05). At 12 months postoperatively, both groups showed significant improvements in LL, DH, and DSCA compared to preoperative values ( P<0.05), but there were no significant differences between the two groups ( P>0.05). The fusion rates were 96% in the Endo-PTLIF group and 94% in the MIS-TLIF group, with no significant difference ( P>0.05). Complications included one case of dural tear in the Endo-PTLIF group, and one case of dural tear and one case of incision infection in the MIS-TLIF group. Conclusion:Endo-PTLIF achieves comparable clinical efficacy to MIS-TLIF in the treatment of single-segment lumbar degenerative diseases, with the added advantages of reduced intraoperative blood loss and faster postoperative recovery.

Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.

Objective:To investigate the early clinical characteristics of elderly patients with severe burns and the risk factors on prognosis.Methods:This study was a retrospective case series study. Clinical data of 124 elderly patients with severe burns who met the inclusion criteria and were admitted to the 12 hospitals from January 2015 to December 2020 were collected, including 4 patients from the Fourth People's Hospital of Dalian, 5 patients from Fujian Medical University Union Hospital, 22 patients from Guangzhou Red Cross Hospital of Jinan University, 5 patients from Heilongjiang Provincial Hospital, 27 patients from the First Affiliated Hospital of Naval Medical University, 9 patients from the First Affiliated Hospital of Nanchang University, 10 patients from Affiliated Hospital of Nantong University, 9 patients from Tongren Hospital of Wuhan University & Wuhan Third Hospital, 12 patients from the 924 th Hospital of PLA, 6 patients from Zhangjiagang First People's Hospital, 4 patients from Taizhou Hospital of Zhejiang Province, and 11 patients from Zhengzhou First People's Hospital. The patients' overall clinical characteristics, such as gender, age, body mass index, total burn area, full-thickness burn area, inhalation injury, causative factors, whether combined with underlying medical diseases, and admission time after injury were recorded. According to the survival outcome within 28 days after injury, the patients were divided into survival group (89 cases) and death group (35 cases). The following data of patients were compared between the two groups, including the basic data and injuries (the same as the overall clinical characteristics ahead); the coagulation indexes within the first 24 hours of injury such as prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time, D-dimer, fibrinogen degradation product (FDP), international normalized ratio (INR), and fibrinogen; the blood routine indexes within the first 24 hours of injury such as white blood cell count, platelet count, neutrophil-to-lymphocyte ratio, monocyte count, red blood cell count, hemoglobin, and hematocrit; the organ function indexes within the first 24 hours of injury such as direct bilirubin, total bilirubin, urea, serum creatinine, aspartate aminotransferase, alanine aminotransferase, total protein, albumin, globulin, blood glucose, triglyceride, total cholesterol, alkaline phosphatase, creatine kinase, electrolyte indexes (potassium, sodium, chlorine, calcium, magnesium, and phosphorus in blood), uric acid, myoglobin, and brain natriuretic peptide; the infection and blood gas indexes within the first 24 hours of injury such as procalcitonin, C-reactive protein, pH value, oxygenation index, base excess, and lactate; treatment such as whether conducted with mechanical ventilation, whether conducted with continuous renal replacement therapy, whether conducted with anticoagulation therapy, whether applied with vasoactive drugs, and fluid resuscitation. The analysis was conducted to screen the independent risk factors for the mortality within 28 days after injury in elderly patients with severe burns. Results:Among 124 patients, there were 82 males and 42 females, aged 60-97 years, with body mass index of 23.44 (21.09, 25.95) kg/m 2, total burn area of 54.00% (42.00%, 75.00%) total body surface area (TBSA), and full-thickness burn area of 25.00% (10.00%, 40.00%) TBSA. The patients were mainly combined with moderate to severe inhalation injury and caused by flame burns. There were 43 cases with underlying medical diseases. The majority of patients were admitted to the hospital within 8 hours after injury. There were statistically significant differences between patients in the 2 groups in terms of age, total burn area, full-thickness burn area, and inhalation injury, and PT, APTT, D-dimer, FDP, INR, white blood cell count, platelet count, urea, serum creatinine, blood glucose, blood sodium, uric acid, myoglobin, and urine volume within the first 24 hours of injury (with Z values of 2.37, 5.49, 5.26, 5.97, 2.18, 1.95, 2.68, 2.68, 2.51, 2.82, 2.14, 3.40, 5.31, 3.41, 2.35, 3.81, 2.16, and -3.82, respectively, P<0.05); there were statistically significant differences between two groups of patients in whether conducted with mechanical ventilation and whether applied with vasoactive drugs (with χ2 values of 9.44 and 28.50, respectively, P<0.05). Age, total burn area, full-thickness burn area, serum creatinine within the first 24 hours of injury, and APTT within the first 24 hours of injury were the independent risk factors for the mortality within 28 days after injury in elderly patients with severe burns (with odds ratios of 1.17, 1.10, 1.10, 1.09, and 1.27, 95% confidence intervals of 1.03-1.40, 1.04-1.21, 1.05-1.19, 1.05-1.17, and 1.07-1.69, respectively, P<0.05). Conclusions:The elderly patients with severe burns had the injuries mainly from flame burns, often accompanied by moderate to severe inhalation injury and enhanced inflammatory response, elevated blood glucose levels, activated fibrinolysis, and impaired organ function in the early stage, which are associated with their prognosis. Age, total burn area, full-thickness burn area, and serum creatinine and APTT within the first 24 hours of injury are the independent risk factors for death within 28 days after injury in this population.

Epilepsies are a group of chronic neurological disorders characterized by spontaneous recurrent seizures caused by abnormal synchronous firing of neurons and transient brain dysfunction. The underlying mechanisms are complex and not yet fully understood. Endoplasmic reticulum (ER) stress, as a condition of excessive accumulation of unfolded and/or misfolded proteins in the ER lumen, has been considered as a pathophysiological mechanism of epilepsy in recent years. ER stress can enhance the protein processing capacity of the ER to restore protein homeostasis through unfolded protein response, which may inhibit protein translation and promote misfolded protein degradation through the ubiquitin-proteasome system. However, persistent ER stress can also cause neuronal apoptosis and loss, which may aggravate the brain damage and epilepsy. This review has summarized the role of ER stress in the pathogenesis of genetic epilepsy.

Objective:To analyze long-term outcomes of inoperable non-metastatic pancreatic cancer patients treated with definitive radiotherapy-based comprehensive treatment.Methods:Clinical data of 168 patients with medically unfit, refusal to surgery or inoperable non-metastatic pancreatic cancer treated with radiotherapy-based comprehensive treatment in PLA General Hospital between January 2016 and December 2020 were retrospectively analyzed. Survival outcomes,prognostic factors and patterns of treatment failure were analyzed in the radiotherapy ( n=95) and combined chemoradiotherapy ( n=73) groups. The survival analysis was conducted by Kaplan-Meier method. The survival curve was compared by log-rank test. Independent prognostic factors were identified by Cox proportional harzard model. Results:With a median follow-up of 20.2 months in the entire group, the median overall survival (OS) and median progression-free survival (PFS) were 18.0 and 12.3 months. The corresponding median OS and median PFS after receiving radiotherapy were 14.3 and 7.7 months. The 1-, 2-and 3-year OS rates were 72.1%, 36.6% and 21.5%, and the 1- and 2-year local control rates were 82.6% and 64.3%, respectively. The median OS for stage Ⅰ, stage Ⅱ and stage III were 27.1, 18.0 and 17.0 months, respectively. There was no significant difference in the median OS of patients with localized disease (stage Ⅰ-Ⅱ) between the radiotherapy and combined chemoradiotherapy groups (21.1 vs. 20.4 months, P=0.470). In patients with locally advanced disease (stage Ⅲ), combined chemoradiotherapy group showed better median OS compared with radiotherapy group (19.2 vs. 13.8 months, P=0.004). Clinical stage, CA19-9 before radiotherapy, comprehensive treatment and biological effective dose (BED 10) were identified as the independent prognostic factors for OS ( P=0.032, 0.011, 0.003 and 0.014). The cumulative 1- and 2-year actuarial rates of treatment failure, local-regional recurrence and distant metastasis were 48% and 74.4%, 15.0% and 27.4%, 23.6% and 33.1%, respectively. Liver metastasis (16.1%, 27/168) and local recurrence (11.9%, 20/168) were the primary patterns of treatment failure. Conclusions:Definitive radiotherapy-based comprehensive treatment effectively prolongs long-term survival in patients with inoperable non-metastatic pancreatic cancer. Definitive radiotherapy can be an alternative treatment option with curative intent for patients with localized pancreatic cancer who are medically unfit or refuse to undergo surgery. The combination of radiotherapy and chemotherapy remains an effective treatment choice for locally advanced unresectable pancreatic cancer.

OBJECTIVE:To investigate the effects of different doses of tanshinone ⅡAon hemodynamics in patients underwent non-extracorporeal circulation coronary artery bypass grafting(NECCABG). METHODS:A total of 66 patients underwent selective NECCABG during Nov. 2016-Apr. 2017 were selected and divided into control group(33 cases)and observation group(33 cases) according to random number tablet. Both groups were given Tanshinone ⅡAsodium sulfonate injection with loading dose of 0.4 μg/kg for 10 min at the beginning of surgery. Control group was given Tanshinone ⅡAsodium sulfonate injection 0.2 μg/(kg·h) continuously till the end of surgery;observation group was given 0.4 μg/(kg·h)continuously till the end of surgery. HR,MAP, central venous pressure(CVP),mean pulmonary arterial pressure(MPAP),pulmonary capillary wedge pressure(PCWP),cardiac index(CI),systemic vascular resistance index(SVRI),pulmonary circulation resistance index(PVRI)and the occurrence of ADR were observed in 2 groups before anesthesia induction(T0),5 min after tracheal intubation(T1),at the moment of sternum cut(T2),at the end of anastomosis of anterior descending branch(T3),at the end of anastomosis of right coronary artery(T4),at the end of operation(T5). RESULTS:At T0,there was no statistical significance in HR,MAP,CVP,MPAP,PCWP, CI,SVRI or PVRI between 2 groups(P>0.05). At T1-T5, HR,MAP,CVP,MPAP,PCWP,SVRI and PVRI of control group were significantly higher than at T0,with statistical significance(P<0.05). There was no statistical significance in CI of control group among at T1-T5and with at T0;there was no statistical significance in HR,MAP,CVP,MPAP,PCWP,SVRI or PVRI of observation group between at T1-T5with at T0 (P>0.05). At T1-T5,CI of observation group was significantly higher than at T0and than control group;HR,MAP,CVP, MPAP,PCWP,SVRI and PVRI were significantly lower than control group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups during medication. CONCLUSIONS:Tanshinone ⅡA0.4 μg/(kg·h)is helpful to keep hemodynamics stable and improve heart function in patients with NECCABG with good safety.
