Objective:To analyze the effects of shared decision-making in patients with type 2 diabetic mellitus.Methods:Databases including PubMed, Web of Science, Embase, Cochrane Library, CNKI, Wanfang Datebase, COVIP and SinoMed, for randomized controlled trials (RCTs) on the application of shared decision-making in patients with type 2 diabetic mellitus from inception to July 22, 2023, used R Studio software for meta-analysis.Results:A total of 14 RCTs and 2 606 patients with type 2 diabetic mellitus were included. The results of meta-analysis showed that the shared decision-making can alleviate the decision-making conflict of type 2 diabetic mellitus patients ( MD=-3.18, 95% CI -5.36 to -0.99, P<0.05), improve the decision-making self-efficacy ( MD=5.82, 95% CI 2.34 to 9.30, P<0.05), medication compliance ( RR=1.08, 95% CI 1.01 to 1.16, P<0.05), and diabetes-related knowledge ( SMD=0.46, 95% CI 0.16 to 0.75, P<0.05), reduce BMI ( MD=-0.75, 95% CI-1.33 to -0.17, P<0.05) and the HbA1c level ( MD=-0.45, 95% CI -0.65 to -0.24, P<0.05) in the 3-month follow-up. Conclusions:The shared decision-making improves the self-management in patients with type 2 diabetic mellitus. However, the long-term effect and potential risks of this model still need to be further studied. It is suggested that the application of shared decision-making in type 2 diabetic mellitus patients should be optimized in the future, and research on the long-term effects and potential risks of this model should be increased.

Objective To investigate the effect of tissue-resident memory T cells(TRM)on imiquimod-induced psoriatic-like skin lesions in mice,and to elucidate the underlying mechanisms of TRM involvement in this process.Methods Forty female BALB/c mice were procured and randomly allocated into four groups:ten in the blank control group,and thirty for the establishment of a psoriasis mouse model.Following successful modeling,the thirty mice were further randomized into three groups:the model control group,the methotrexate-treated group,and the imiquimod-treated group,with ten mice in each group.Mice in the blank control group and model control group were uniformly treated with Vaseline for intervention.The methotrexate group and the imiquimod group were treated with 62.5mg of 5％imiquimod cream.The methotrexate group was administered by gavage at a dose of 1 mg/kg,and the gavage volume of each group was 10 mL/kg.The model control group,blank group and imiquimod group were gavaged with the same volume of normal saline.Treatment was conducted over six consecutive days.Subsequently,comparisons were made across groups regarding the psoriasis area and severity index(PASI),histopathological findings,inflammatory cytokine levels,and TRM cell levels.Results(1)The imiquimod group exhibited signifi-cantly lower scores for erythema(2.54±0.32),skin thickening(2.59±0.25),and scaling(2.52±0.29)compared to the methotrexate group,model control group,and blank control group(P<0.05).Additionally,the methotrexate group demonstrated reduced scores for erythema,skin thickening,and scaling compared to the model control group(P<0.05).(2)Hematoxylin-eosin(HE)staining revealed that the epidermis in the methotrexate group became thin-ner,with fewer parakeratotic cells and increased hair follicles.Conversely,the imiquimod group displayed abnor-mal cell morphology and relatively thicker white skin after modeling.(3)The imiquimod group showed significantly lower levels of TNF-α(51.63±4.39 pg/mL),IL-1β(35.53±4.15 pg/mL),IFN-γ(23.43±3.41 pg/mL),and IL-23(15.24±2.95 pg/mL)compared to the methotrexate and model control groups(P<0.05).Similarly,the methotrexate group exhibited reduced levels of TNF-α,IL-1β,IFN-γ,and IL-23 compared to the model control group(P<0.05).(4)The imiquimod group had significantly lower levels of CD8+CD103+cells(15.39±2.31)than the methotrexate and model control groups(P<0.05).Furthermore,the methotrexate group demonstrated lower levels of CD8+CD103+cells compared to the model control group(P<0.05).Conclusion Miquimod induces heavier skin lesions,faster response,and more epidermal thickening in psoriasis like mice.CD8+CD103+TRM cells and inflammatory factors may be involved in the recurrence of psoriasis.

With the intensification of population aging, type 2 diabetes has emerged as a significant global public health concern, particularly in developing countries.Epidemiological data indicate that the elderly population faces a higher risk of diabetes, accompanied by an increasing incidence rate.Due to the unique pathological characteristics and comorbid chronic diseases prevalent among elderly diabetes patients, polypharmacy is both common and often unavoidable.Inappropriate polypharmacy poses heightened health risks for patients and complicates clinical management, underscoring the urgent need to optimize intervention strategies.Effective approaches include regular medication reviews, adjustments to blood glucose control targets, and the development of personalized deprescribing plans informed by comprehensive geriatric assessments.While some interventions have demonstrated positive effects in reducing potentially inappropriate medications, addressing prescription omissions, and enhancing medication adherence, their capacity to yield significant clinical improvements requires further validation.Future research should prioritize the identification of the most effective interventions for high-risk populations.

Objective:To observe the long-term effect of superficial temporal fascia flap combined with severed auricle reimplantation in emergency repair of partial auricle of complete separation.Methods:The data of patients with partial auricle of complete separation admitted to Emergency Clinic of Burn and Plastic Surgery of General Hospital of Northern Theater Command from June 2014 to August 2023 were retrospectively analyzed. All of them were repaired with a superficial temporal fascia flap combined with amputating auricle reimplantation. During the operation, the superficial temporal fascia flap was harvested, and the pedicle was preserved. Then the detached auricular cartilage was removed and used as a replantation scaffold. Then the remaining skin was thinned to create a full-thickness skin graft after cartilage detachment. Referring to the position and angle of the contralateral auricle, the cartilage scaffold was sutured and fixed at the stump of the ear cartilage. The wound was covered with a superficial temporal fascia flap and a full-thickness skin graft, and then packed and sutured. The postoperative observation indicators mainly confirm whether the surgery was successful, the healing condition of the replanted ear, and whether there were problems such as skin flap necrosis, infection, hematoma, etc. The shape, color, texture and tactile recovery of the reconstructed auricle were evaluated by long-term follow-up for more than 1 year. The Vancouver scar scale (VSS) was used to assess scarring in both donor and recipient sites (total score of 0-15 points, higher scores indicated more severe scarring). The Likert 5-level scoring method was used to evaluate the patients’ satisfaction with the surgical results (total score of 30 points, ≥27 points were very satisfied, 24-26 points were somewhat satisfied, 18-23 points were indifferent, 15-17 points were somewhat dissatisfied, ≤14 points were very dissatisfied).Results:A total of 8 patients were enrolled, including 5 males and 3 females. Their ages ranged from 26 to 65 years, with an average of 41 years. All patients had unilateral ear defects, with 3 cases in the left ear and 5 cases in the right ear. The defect areas ranged from 1.5 cm × 2.5 cm to 5.0 cm × 4.0 cm. During the surgery, the harvested superficial temporoparietal fascia flaps ranged from 4.5 cm × 6.5 cm to 15.0 cm × 10.0 cm. After surgery, both the flaps and full-thickness skin graft healed satisfactorily, with primary healing observed in both the donor and recipient sites. There were no complications such as necrosis, infection, or hematoma were observed. The follow-up period ranged from 3 to 9 years, with an average of approximately 6.3 years. Except for one case that required a defatted surgery at the second stage, the reconstructed auricles of the remaining patients were basically consistent with the healthy side, with smooth contour lines, skin color and texture close to the surrounding tissues, and improved tactile sensitivity. In the final follow-up, the VSS scores for both the donor and recipient sites were ≤3 for all patients. All patients rated the surgical outcome as very satisfied.Conclusion:For the partial auricle of complete separation that has no chance of replantation, the use of superficial temporal fascia flap and detached ear composite graft to repair is a reliable and effective surgical method. Patients have good postoperative long-term effects and high levels of satisfaction.

Objective:To study positive rates and typing of oligoclonal bands (OCB) in patients with neurological disorders, and to reveal the clinical significance and applicational value of OCB test.Methods:A retrospective analysis was performed on the detection results of 3 217 patients with neurological disorders who undertook both serum and cerebrospinal fluid OCBs in the First Hospital of Peking University from January 2012 to August 2022. According to the final diagnosis, the patients were divided into 13 groups including multiple sclerosis (479 cases), neuromyelitis optica spectrum disorders (935 cases), autoimmune encephalitis (192 cases), viral encephalitis (94 cases), nervous system complication after HSCT (232 cases), Guillain-Barré syndrome (644 cases), chronic inflammatory demyelinating polyneuropathy (157 cases), etc. Cerebrospinal fluid and serum OCBs were detected using isoelectric focusing electrophoresis combining immunofixation, then classified into Ⅰ-Ⅴ types according to the morphology. Consequently, positive rates and types were analyzed for each group. χ2 test was used for comparison between groups. Results:The positive rates of cerebrospinal fluid OCB in multiple sclerosis, nervous system complication after hematopoietic stem cell transplantation (HSCT), autoimmune encephalitis, viral encephalitis, neuromyelitis optica spectrum disorders, Guillain-Barré syndrome and chronic inflammatory demyelinating polyneuropathy were respectively 66.8% (320/479), 48.7% (113/232), 46.4%(89/192), 19.1% (18/94), 17.6% (165/935), 9.9% (64/644), 5.1% (8/157). For patients with multiple sclerosis, neuromyelitis optica spectrum disorders, viral encephalitis, and autoimmune encephalitis, Type Ⅱ bands took the majority of cerebrospinal fluid OCB-positive cases with the rates of 94.1% (301/320), 78.7% (70/89), 77.8% (14/18), and 77.6% (128/165) respectively, indicating intrathecal IgG synthesis; for patients with nervous system complication after HSCT, Guillain-Barré syndrome and chronic inflammatory demyelinating polyneuropathy, type Ⅳ bands took the majority of cerebrospinal fluid OCB-positive cases with the rates of 94.7% (107/113), 82.8% (53/64) and 100% (8/8), indicating no obvious intrathecal IgG synthesis. The positive rates of cerebrospinal fluid oligoclonal bands were significantly different among all groups (χ 2=1 268.31, P<0.001). Conclusion:The positive rates of cerebrospinal fluid oligoclonal bands are different among different neurological disorders, in which the positive rate of cerebrospinal fluid OCB is higher with type Ⅱ bands as the majority type in multiple sclerosis, which indicates that the detection and typing of cerebrospinal fluid OCB are helpful for the diagnosis of various neurological diseases, especially for multiple sclerosis.

Objective:To investigate the correlation between liver stiffness and histopathological changes in a rat model of acute hepatitis using virtual touch tissue imaging quantification (VTIQ) technology.Methods:A total of 100 SPF-grade SD rats were randomly divided into 3 groups: control ( n=30), low-dose ( n=35), and high-dose ( n=35) groups. Acute hepatitis models were induced in the low-dose and high-dose groups using 400 mg/kg and 600 mg/kg of Thioacetamide (TAA), respectively. Liver stiffness parameters of the right median lobe and right lobe were measured using VTIQ technology, Mean-H and Mean-L represent the liver lobes with higher and lower liver stiffness measurments, respectively, while Mean represent the average of the measurements from both liver lobes. Comparative analyses of liver stiffness parameters were performed across three groups and between the two lobes of the liver. The correlations between the Mean values of liver stiffness and semi-quantitative histopathological data were investigated. Ten rats were randomly selected from each of the 3 groups to test the repeatability of VTIQ values before and after euthanasia with intraperitoneal anesthesia. Subsequently, 10 rats after euthanasia from each 3 group were randomly chosen to assess the repeatability of VTIQ measurements for inter-observer and intra-observer variabilities. Results:VTIQ results showed statistically significant differences in Mean, Mean-H, and Mean-L among the 3 groups (all P<0.01). The high-dose group had higher measurements compared to the low-dose and control groups, with significant intergroup differences (all P<0.01). Significant differences in Mean-H and Mean-L were observed between the two liver lobes in both low and high-dose groups (all P<0.01). The Mean value showed significant positive correlations with semi-quantitative histopathological data of hepatocellular edema, periportal inflammatory cell infiltration, macrophage proliferation, and bile duct proliferation ( r=0.391, 0.648, 0.577, 0.542; all P<0.01). Multivariate linear regression analysis indicated that hepatocellular edema, eosinophilic change, and bile duct proliferation significantly and positively predicted the Mean value (β=-0.278, -0.196, -0.333; all P<0.05). There were no significant differences of VTIQ measurements befor and after euthanasia (all P>0.05), with repeatability coefficients of 0.166, 0.182, 0.185 for Mean, Mean-H, and Mean-L, respectively. Post-euthanasia, inter- and intra-observer VTIQ differences remained non-significant (all P>0.05), with Mean, Mean-H, Mean-L coefficients of 0.114, 0.194, 0.165 and 0.206, 0.322, 0.268, respectively. Conclusions:VTIQ technology demonstrates potential clinical value in assessing a rat model of acute hepatitis, offering a new perspective for non-invasive evaluation of acute hepatitis. However, its clinical application requires further validation.
