Severe open tibiofibular fractures account for approximately 28.1% of all open fractures. Among them, Gustilo-Anderson type IIIB/C fractures present significant clinical challenges due to associated bone and soft tissue defects, high infection rates, and risk of amputation. Inadequate preoperative assessment may lead to suboptimal emergency surgical planning or intraoperative complications. Historically, external fixation was often preferred, but this approach has been associated with limitations such as restricted joint mobility, delayed bone union, joint stiffness, and disuse osteoporosis, resulting in poor functional recovery. With advancements of debridement techniques, standardization of antibiotic use, and popularization of early soft tissue coverage, early internal fixation has gained broader acceptance. Nevertheless, controversies persist regarding the choice of fixation method, timing of definitive fixation, use of reamed versus unreamed intramedullary nailing, and necessity of fibular fixation. To standardize the diagnosis and early management of severe open tibiofibular fractures, reduce complication rates, and improve functional recovery, the Society of Microsurgery of the Chinese Medical Association organized a panel of domestic experts to develop the Evidence-based guideline for the diagnosis and early fixation of severe open tibiofibular fractures ( version 2025), using evidence-based methodology. The guidelines provided 12 recommendations covering diagnostic and early fixation strategies of severe open tibiofibular fractures, aiming to provide clinicians with scientifically grounded and standardized guidance.

Objective:To construct an evaluation index system for rural order-oriented general practice residents based on Entrustable Professional Activities (EPAs) and conduct an empirical analysis. ?Methods:A mixed-methods study design was adopted (November 2022-April 2023). The preliminary draft of the index system was developed through literature review and group discussions, then refined and improved via two rounds of expert consultation using the Delphi method. The analytic hierarchy process (AHP) was applied to determine the weight of each index. Meanwhile, questionnaires were distributed to 181 participants, including general practitioners from general hospitals, general practitioners from community hospitals, and general practice residents. The scores of the three groups regarding the importance and feasibility of the indices were compared. Ten general practitioners of the above three types were selected for semi-structured interviews on their cognitive and practical aspects of the system. ?Results:The positive coefficients of the two rounds of expert consultation were 16/17 and 16/16, respectively. The expert authority degree was >0.70, and the test of coordination coefficient was statistically significant ( P<0.05). Finally, an index system consisting of 20 first-level indices and 56 second-level indices was established. In terms of weight, among the first-level indices,"EPA1: Information Acquisition"had the highest weight (0.11), while"EPA12: Clinical Research"had the lowest (0.02). Among the second-level indices, "Medical History Taking" and "Physical Examination" under EPA1 had the highest weight (both 0.056), while "Healthcare for Patients with Severe Mental Illness" and "Healthcare for Disabled and Handicapped Populations" under EPA15 had the lowest (both 0.003). The 181 participants gave scores ranging from 4.49 to 4.92 for the importance of the 20 first-level indices and from 4.16 to 4.81 for their feasibility. Only for" EPA19: Common Diseases in Primary Care and Health Management", the feasibility score given by general practitioners from community hospitals was higher than that from general hospitals ( t=2.157, P=0.032); no statistically significant differences were observed among the groups for the other indices ( P>0.05).The interview results showed that general practitioners have a relatively high level of recognition for this system, but there is still room for improvement in its practical application.? Conclusions:The evaluation index system for rural order-oriented general practice residents constructed based on EPAs has high reliability, and it is consistently recognized by different types of general practitioners. It can provide a reference for the cultivation of post competency of this group.?

The paper introduces Professor ZHAO Hong's clinical experience and the thinking of diagnosis and treatment for gynecological diseases based on spleen-stomach theories of TCM and explore the effects of the dysfunction of spleen and stomach on gynecological diseases. In clinical practice, Professor ZHAO proposes the "theory" for protecting the spleen and stomach, and in consideration of the other organs; focuses on the "principle" for strengthening the spleen, harmonizing the stomach, promoting qi circulation, removing stagnation and mutually-regulating the body, qi and mind; and adopts the "methods" of integrating acupuncture with medication and specially uses the warming and resolving techniques. She attaches importance to "acupoints" on the detection, and the selection of fewer but more effective ones; and delivers the "needling techniques" for releasing the stagnation and obstruction and inducing muscle jumping and sensation transmission. Professor ZHAO Hong integrates acupuncture with medication in views of spleen and stomach theories of TCM for ovarian insufficiency, polycystic ovary syndrome, endometriosis, thin endometrium and dysfunctional uterine bleeding, which provides the references for the treatment of gynecological diseases.

Objective To explore the molecular mechanism of circular RNA(circ)VAPA promoting the Hippo pathway to inhibit liver regeneration through the miR-101a-3p/TEAD3 axis.Methods A mouse model of 70％partial hepatectomy-induced liver regeneration was constructed,and the expressions of circVA-PA,miR-101a-3p,and TEAD3 were analyzed.Mouse embryonic hepatocyte BNL CL.2 cells were transfected with siRNA or overexpression plasmids and divided into the VAPA-NC group,the VAPA-NC+miR-101a-3p mimic group,the VAPA-NC+miR-101a-3p mimic-NC group,the VAPA-OE group,the VAPA-OE+miR-101a-3p mimic group and the VAPA-OE+miR-101a-3p mimic-NC group.CCK-8 method and flow cytometry were used to analyze the proliferation,apoptosis,and cell cycle changes of hepatocytes.Immunofluorescence staining was used to analyze the nuclear translocation of YAP1.Quantitative Reverse Transcription Real-Time PCR(qRT-PCR)was used to analyze the expressions of key genes in the Hippo pathway.The dual-lu-ciferase reporter gene assay was used to verify the targeting relationships between circVAPA and miR-101a-3p,as well as between miR-101a-3p and TEAD3.Results The level of circVAPA gradually increased during liver regeneration(P＜0.05),while the level of miR-101a-3p first increased and then decreased(P＜0.05).When miR-101a-3p was overexpressed alone,the cell proliferation rate was the highest(P＜0.05),but it had no effect on the cell apoptosis rate(P＞0.05).When circVAPA was overexpressed alone,it had no effect both on the cell proliferation rate and apoptosis(P＞0.05).After co-overexpression of circVAPA and miR-101a-3p,the cell proliferation rate significantly decreased,and the cell apoptosis significantly increased(P＜0.05).When miR-101a-3p was overexpressed alone,a large number of cells entered into the S phase.After co-overex-pression of circVAPA and miR-101a-3p,a large number of cells were blocked in the G2/M phase.The phos-phorylation level of the Hippo upstream gene YAP1 significantly increased at 6 hours after liver regeneration(P＜0.05)and then rapidly decreased.However,co-overexpression of circVAPA and miR-101a-3p did not af-fect the level of p-YAP1 and the nuclear translocation of YAP1(P＞0.05).The expression levels of the Hip-po downstream gene CTGF and the transcription factor TEAD3 first increased and then decreased during liver regeneration(P＜0.05),and there was no significant change in CYR61(P＞0.05).After co-overexpression of circVAPA and miR-101a-3p,the expression level of CTGF increased(P＜0.05).Knocking down or overex-pressing circVAPA did not affect the expression of TEAD3(P＞0.05),while overexpressing miR-101a-3p could significantly inhibit the expression level of TEAD3(P＜0.05).The dual-luciferase reporter gene assay confirmed the targeting relationships between circVAPA and miR-101a-3p,as well as between miR-101a-3p and TEAD3.Conclusion circVAPA promotes the Hippo pathway to inhibit liver regeneration through the miR-101a-3p/TEAD3 axis.

Objective:To investigate the related factors of pleasure loss in patients with human immunodefi-ciency virus(HIV)/acquired immune deficiency syndrome(AIDS).Methods:Totally 237 patients with HIV/AIDS from a certain infectious disease hospital were selected and surveyed with a self-designed general information ques-tionnaire,the Temporal Pleasure Experience Scale(TEPS),Self Acceptance Scale(SAQ),Discrimination Percep-tion Scale(SIS),and Perceived Social Support Scale(PSSS).Results:The patient's TEPS score was(73.4±16.1).Stepwise linear regression analysis showed that the PSSS total scores,education level,and personal monthly income were positively correlated with the TEPS total scores(β=0.41,5.17,4.63),and age was negatively corre-lated with the TEPS total scores(β=-0.30).Conclusion:It suggests that more attention should be paid to the lack of pleasure in patients with HIV/AIDS,and the lack of pleasure is related to personal monthly income,educa-tion level,age and perceived social support.

Objective:To assess the utility of whole-genome sequencing (WGS) in predicting Mycobacterium tuberculosis resistance to fluoroquinolones (FQs) and to establish a quantitative relationship between resistant gene mutations and resistance levels. Methods:A total of 296 drug-resistant tuberculosis surveillance strains with various resistance profiles, preserved by the National Tuberculosis Reference Laboratory of the Tuberculosis Prevention and Control Center at the Chinese Center for Disease Control and Prevention between 2013 and 2020, were included as study subjects. The Sensititre? MYCOTBI microplate method and WGS were used to assess the phenotypic and genotypic drug sensitivity of Mycobacterium tuberculosis to ofloxacin and moxifloxacin. Sensitivity, specificity, and concordance (Kappa value) of WGS in predicting fluoroquinolone sensitivity were calculated using phenotypic drug susceptibility testing (DST) results as the gold standard. A summary analysis was conducted on the distribution of drug resistance mutation sites and resistance levels. The paired χ 2 test was used to compare the detection rates between the two methods, with P<0.05 indicating statistical significance. Results:Among the 296 Mycobacterium tuberculosis strains with different resistance profiles, 196 were rifampicin-resistant, 50 were resistant to other drugs, and 50 were fully sensitive. WGS identified 81 strains carrying FQs resistance-related mutations, primarily at gyrA codons 94, 90, and 91. Sensitivity, specificity, and consistency (Kappa value) of WGS in predicting ofloxacin resistance were 86.5%, 98.1%, and 0.87, respectively. For moxifloxacin resistance prediction, these values were 80.0%, 99.5%, and 0.83, respectively. There was no statistically significant difference between the phenotypic DST and WGS detection rates for ofloxacin resistance (30.1% vs 27.4%, χ 2=3.06, P=0.08). However, the phenotypic DST detection rate for moxifloxacin resistance (33.8%, 100/296) was significantly higher than that of WGS (27.4%, 81/296) (χ 2=15.43, P<0.01). Analysis of the distribution of resistance mutation sites and resistance levels showed that different mutation sites corresponded to different minimum inhibitory concentrations (MICs). Multiple mutation combinations, including gyrA_D94G, gyrA_D94Y, and gyrA_D94N were mainly associated with high-level resistance, while gyrA_D94A, gyrA_A90V, and gyrA_S91P were primarily linked to low-level resistance. Conclusion:WGS demonstrates favorable sensitivity, specificity, and consistency in predicting FQs resistance and can partially predict resistance levels.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

β-thalassemia is a single-gene genetic disease caused by β globin gene mutations leading to the fact that red blood cells are unable to form normal adult hemoglobin, and then patients develop hemolytic anemia. Current treatment regimens mainly include allogenetic hematologic stem cell transplantation, symptomatic regular blood transfusions and the use of iron removers to reduce iron load. Some severe patients have quite poor prognoses and deadly consequences if not treated timely. Genetically modified autohematopoietic stem cells can provide a new treatment option for patients with β thalassemia, which may achieve a long-term and stable increase in hemoglobin level through a single dose, making one-time cure β-thalassemia possible. This paper reviews the key elements of clinical trial design for β-thalassemia gene therapy from the aspects of efficacy evaluation endpoints, clinical trial design, enrollment population, and subject monitoring in order to provide a reference for pharma-therapeutic research and development enterprises.
