Objective To summarize and analyze the efficacy and influencing factors of second allogeneic hematopoietic stem cell transplantation (allo-HSCT) for acute leukemia relapsing after the first allo-HSCT. Methods Clinical data of 17 patients with acute leukemia who underwent second allo-HSCT at Peking University First Hospital from January 2005 to December 2024 were retrospectively analyzed. Results Among the 17 patients, 7 achieved long-term disease-free survival after second transplantation. The median progression-free survival after successful second transplantation was 7 months (range 8 days to 69 months). The relapse fatality was 24%, and the transplant-related fatality was 35%. Conclusions Second transplantation is an effective treatment for relapsed and refractory acute leukemia, but the relapse fatality and transplant-related fatality remain high. Patient age, time of relapse after the first transplantation and disease status before second transplantation are all factors that affect the efficacy of second transplantation. Younger age, late relapse and complete remission of disease before second transplantation are all beneficial for long-term disease-free survival after second transplantation.

This paper systematically reviewed the concept of authentication studies on traditional Chinese medicine （TCM） classics and the research achievements of scholars across historical and contemporary periods. We categorized the authentication studies on TCM classics into four types， including work-oriented authentication research， metho-dological studies on authentication， extended authentication research， and single-book authentication. Multiple methods were applied comprehensively， including investigating bibliographic documents of successive dynasties， analyzing the academic contents of medical books， studying the textual characteristics of medical books， examining the cited references in medical books， verifying the biographies of authors， and analyzing the interpolations and accretions in medical books， to distinguish the authenticity of TCM classics. The academic value of authenticity identification of TCM classics is concluded in three aspects，i.e. it serves as an important means to distinguish authenticity from falsehood in TCM classics， an important guarantee for inheriting the essence of TCM literature， and a key to unlocking the academic treasure trove of TCM classics and achieving inheritance-based innovation， which will lay a solid documentary foundation for constructing identification methodologies and standardized systems.

AIM: To investigate the abnormal conditions and change patterns of accommodative facility in patients with different refractive states before and after small incision lenticule extraction(SMILE)surgery.METHODS:A prospective clinical cohort study was conducted. A total of 59 patients(118 eyes)who underwent SMILE surgery and had visual function files established in our hospital from June to December 2023 were randomly selected, including 37 males and 22 females, aged 18-35 years(with an average age of 25.19±5.65 years). According to the preoperative spherical equivalent(SE), they were divided into two groups: the low-to-moderate myopia group(SE≥-6.00 DS)with 40 patients(80 eyes), and the high myopia group(SE<-6.00 DS)with 19 patients(38 eyes). The monocular and binocular accommodative facility before surgery and at 1 wk and 1 mo after surgery were compared, and the changes in accommodative facility before and after SMILE surgery in the two groups of patients were analyzed.RESULTS:All surgeries were completed successfully. In the low-to-moderate myopia group, 33 cases(66 eyes)completed the 1-month follow-up after surgery, with a loss to follow-up rate of 17.5%(7/40). In the high myopia group, 15 patients(30 eyes)completed the 1-month follow-up after surgery, with a loss to follow-up rate of 21.1%(4/19). After SMILE surgery, the uncorrected visual acuity and SE of both low-to-moderate myopia and high myopia were significantly improved(all P<0.05). The accommodative facility of the right eyes in all the patients at 1 mo after surgery was better than that before surgery and at 1 wk after surgery(P=0.002, 0.006), the accommodative facility of the left eyes was significantly increased at 1 mo after surgery than that at 1 wk after surgery(P=0.005), and the binocular accommodative facility at 1 mo after surgery was significantly increased compared with that before surgery(P<0.017). Furthermore, there were statistical significance in accommodative facility of the right eyes in the low-to-moderate group at 1 mo compared with that before surgery and at 1 wk after surgery(P=0.011, 0.004); it was significantly increased in the left eyes at 1 mo after surgery compared with that at 1 wk after surgery(P=0.001), and binocular accommodative facility at 1 mo after surgery was significantly better than that before surgery(P<0.001). Furthermore, there was no statistical significance in the right, left and binocular accommodative facility of patients in the high myopia group(all P>0.017).CONCLUSION: After SMILE surgery, the monocular accommodative facility shows a transient decrease and then exceeds the preoperative level at 1 mo after surgery, and the binocular accommodative facility gradually improves after surgery. SMILE surgery has a positive impact on the monocular and binocular accommodative facility in patients with low-to-moderate myopia, but has no significant impact on the accommodative facility in patients with high myopia. It is of clinical significance to strengthen the detection of monocular and binocular accommodative facility before and after SMILE surgery.

AIM: To analyze the changes in binocular visual function before and after small incision lenticule extraction(SMILE)in patients with different degrees of myopia.METHODS:A prospective non-randomized controlled study was conducted. A total of 94 patients(188 eyes)who visited the refractive outpatient department of the ophthalmology department of the General Hospital of the PLA from June 2022 to June 2023 and voluntarily chose SMILE were consecutively included. They were grouped according to the degree of myopia, including 24 cases(48 eyes)in the low myopia group(-3.00 D

Hypercoagulable state (HCS) after kidney transplantation is one of the common and serious complications in kidney transplant recipients, which has attracted increasing attention in recent years. HCS refers to the abnormal and excessive activation of blood coagulation function, leading to the increased risk of thrombosis. After kidney transplantation, the combined effects of hemodynamic changes, surgical trauma and severe rejection increase the incidence of HCS, not only raising the risk of thrombosis but also potentially causing graft failure and affecting the postoperative survival rate of patients. This article reviews the influencing factors, clinical manifestations, diagnostic methods and preventive strategies of HCS after kidney transplantation, aiming to provide a theoretical basis for optimizing perioperative management and improving the prognosis of patients.

Objective To investigate the alterations in skeletal muscle function and mass in an experimental mouse model of high-intensity exercise in a hot and humid environment.Methods Twenty-four male C57BL/6J mice(7～8 weeks old,weighing 21.30±0.67 g)were randomly assigned to a control group(CON group),a normal temperature and humidity exercise group(NE group),and a high temperature and humidity exercise group(HE group),with 8 mice in each group.The HE group was subjected to a high-temperature simulation chamber,maintaining a temperature of 37～39℃and humidity of 70%～80%,for a 60-minute exercise intervention at a 10° incline and 80%of maximum velocity(12 min of exercise followed by 8 min of rest,for 3 cycles).The CON group did not exercise,while the NE group exercised in the same manner in a normal temperature and humidity environment.The overall condition of the mice was evaluated by monitoring their body weight and analyzing their body composition.Their serum creatinine and urea levels were detected using an automated biochemical analyzer.After exercise,skeletal muscle function in the mice of each group was assessed by measuring their grip strength and exhaustion time.The skeletal muscle contractility and resistance to fatigue were evaluated using an in situ/in vivo/ex vivo muscle testing system.HE staining was employed to observe the morphological and structural changes in the skeletal muscles,and the average cross-sectional area and diameter of the muscle fibers were analyzed.Genes related to protein synthesis(Eif4ebp1,p70S6k)and breakdown(Foxo3,Fbxo32,Trim63)and heat stress-related genes(Hsf-1,Hspa1a,Hsp90aa)were quantified using RT-qPCR.Results ① Compared with the CON and NE groups,the HE group exhibited significant decreases in body weight(P<0.01)and lean body mass(P<0.05),an upward trend of creatinine level(P<0.05),and increases in the urea content(P<0.01).② The mice in the HE group had notably reduced grip strength(P<0.001),diminished skeletal muscle contraction,and weakened resistance to fatigue(P<0.05)than the CON and NE groups.③ The HE group demonstrated a reduction in the average cross-sectional area of muscle fibers(P<0.05)and a decrease in average fiber diameter(P<0.05),with particular up-regulation of Fbxo32,Trim63 and Eif4ebp1(P<0.01)and down-regulation of p70S6k(P<0.05)in comparison to the NE and CON groups.④ The expression levels of heat stress-related genes were higher in the HE group than the CON and NE groups(P<0.05).Conclusion High-intensity exercise in a hot and humid environment can lead to a decline in skeletal muscle function and mass in mice,potentially due to the disturbance of skeletal muscle protein synthesis and degradation triggered by excessive heat stress.

Objective To analyze the main epidemiological characteristics of fungal infection in this hospital in the past 7 years,and to provide reference for clinical treatment and prevention and control strategies of fun-gal infection.Methods The fungal data and clinical data of related patients isolated from clinical samples in Peking Union Medical College Hospital from early January 2018 to the end of May 2024 were selected,and the main epidemiological characteristics of fungal infection in this hospital were identified and described through multi-angle statistical analysis.Results A total of 4 479 patients with filamentous fungal infection were en-rolled.The proportion of male patients[57.5％(2 576/4 479)]was higher than that of female patients[42.5％(1 903/4 143)],mainly distributed in internal medicine,Intensive Care Unit(ICU)and emergency de-partment,among which internal medicine accounted for the highest proportion[50.0％(2 241/4 479)].About 90.0％of the specimens were from the lower respiratory tract,in addition to specimens from skin and soft tis-sue,tissue,ear and blood culture.In terms of seasonal distribution,there are more patients in winter.The fun-gi were mainly composed of Aspergillus,Mucor,Cerdosporium,Fusarium and Penicillium,among which As-pergillus was the most abundant,accounting for 74.6％of the total.Aspergillus fumigatus was the most a-bundant Aspergillus,accounting for 42.5％of the total Aspergillus(1 418/3 340).Among the related infec-tions caused by mold,Aspergillus was the most common in the lower respiratory tract,accounting for 76.8％.Among them,Aspergillus fumigatus accounted for the highest proportion(33.6％).98.6％of the molds infected the ear were Aspergillus,of which Aspergillus niger and Aspergillus terreus were the most common.Skin infections are mainly caused by Sporothrix schenckii,Trichophyton rubrum,Microsporum ca-nis.The results of in vitro drug sensitivity test showed that the four common Aspergillus isolated in this hos-pital were sensitive to voriconazole,and amphotericin B had better antifungal activity against Mucorales in vitro.Conclusion Based on the main epidemiological characteristics of fungal infections in this hospital,it is recommended that special attention be paid to the admission of patients in the respiratory department during the peak infection period in autumn and winter.In the treatment of fungal infections in different regions and on different body parts,attention should be paid to the differences in the distribution of bacterial species.

OBJECTIVE To provide reference for constructing scientific and reasonable pharmaceutical service mode for hospitalized patients with chronic airway diseases. METHODS From October 2023 to March 2024， 250 patients with chronic obstructive pulmonary disease and acute exacerbation of asthma who were hospitalized in the respiratory department of Hebei General Hospital and received pharmaceutical care （PC） were randomly divided into control group （125 cases） and observation group （125 cases）. The control group received general pharmaceutical services throughout their hospitalization， while the observation group received standardized and graded pharmaceutical services throughout their hospitalization. The differences in clinical value indicators， humanistic value indicators， and quality management indicators were compared among different PC service models. RESULTS Among clinical value evaluation indicators， the observation group had better achievement rate of disease treatment goals， correct use score of inhalation devices， the incidence of adverse drug reactions， and the number of drug-related problems solved than the control group （P＜0.05）. Among the humanistic evaluation indicators， compared with the control group， the observation group had better medication compliance scores， pharmacist intervention success rates， and patient satisfaction scores （P＜0.05）. Among quality management evaluation indicators， the proportion of drug costs， the proportion of intravenous medication， the use rate of antibiotics， the intensity of antibiotic use， and the number of pharmaceutical services in the observation group were significantly better than the control group （P＜0.05）. CONCLUSIONS Standardized and graded pharmaceutical care services have improved the efficiency of pharmacists and service effectiveness， making it a new pharmaceutical service model worth promoting.

Objective:To summarize and analyze the acupoint selection law of acupuncture and moxibustion for the treatment of schizophrenia using data mining techniques and network visualization technology.Methods:The literature related to the treatment of schizophrenia through acupuncture and moxibustion was retrieved from CNKI, Wanfang, VIP, SinoMed, Chinese Medical Journal Full-text Database, PubMed and Web of Science from the establishment of the databases to December 31, 2022. A database was established using Excel 2013 software and frequency analysis of acupoints was conducted; the Apriori algorithm was used to analyze the association law of acupoints; SPSS Statistics 25.0 and SPSS Modeler 18.0 software were used for acupoint clustering analysis to explore the acupoint selection law.Results:A total of 133 articles were included, involving 133 acupuncture prescriptions and 158 acupoints, with a total frequency of 1131 times. The most frequently used acupoints were Baihui (GV20) (71 times), Zusanli (ST36) (51 times), Neiguan (PC6) (45 times). Commonly used meridians were Governor Vessel, and stomach meridian, etc. According to the analysis of association rules, 108 association rules of acupoints were obtained, and common compatibility of acupoints was Baihui (GV20)-Yintang (GV24)-Zusanli (ST36), Baihui (GV20)-Shenting (GV24), Baihui (GV20)-Yintang (GV24), Daling (PC7)-Laogong (PC8), etc. Four major clusters were obtained through clustering analysis of commonly used acupoints.Conclusion:Modern acupuncture and moxibustion is mainly used to regulate yin and yang and balance qi and blood in the treatment of schizophrenia. The acupoint selection is based on Baihui-Yintang-Neiguan-Hegu acupoint prescription, and other acupoints are added according to concurrent syndromes, which can not only give full play to the synergistic effect of acupoints, but also promote the recovery of motor and sensory functions.
