Ulcerative colitis （UC）， a chronic， non-specific inflammatory bowel disease with typical symptoms such as abdominal pain， diarrhea， and bloody stools， demonstrates a high relapse rate and difficulty in curing. Sishenwan， first recorded in Internal Medicine Abstract （Nei Ke Zhai Yao）， are a classic prescription for treating diarrhea caused by deficiency of the spleen and kidney Yang. The core therapeutic principle of Sishenwan is warming and tonifying the spleen and kidney， and astringing the intestine and stopping diarrhea. In recent years， Sishenwan have demonstrated distinct advantages in the clinical treatment of UC. The pathogenesis of UC involves multiple factors， including immune dysregulation and gut microbiota imbalance. Although Western medicine is effective in the short term， its side effects， high relapse rate， and resistance associated with long-term use pose substantial challenges. Sishenwan have shown excellent clinical outcomes in the treatment of UC due to deficiency of the spleen and kidney Yang. Modern clinical studies indicate that Sishenwan， used alone or in combination with Western medicine or other Chinese medicine compound prescriptions， significantly improve the clinical efficacy in treating UC due to deficiency of the spleen and kidney Yang. Sishenwan effectively alleviate core symptoms such as mucus， pus， and blood in stools， and persistent abdominal pain， reduce Mayo scores and the relapse rate， and improve patients' quality of life. Research on the material basis reveals that Sishenwan contain multiple active ingredients such as psoralen， isopsoralen， and evodiamine. Mechanism studies indicate that Sishenwan inhibit the inflammatory cascade reactions by regulating the signal network through multiple targets. Sishenwan regulate cellular immunity and restore intestinal immune homeostasis. At the microecological level， Sishenwan promote the intestinal barrier repair through the "microbiota-metabolism-immunity" axis. The current research still needs to be deepened in aspects such as the mining of specific biomarkers for syndromes and the exploration of the collaborative mechanism of traditional Chinese and Western medicine. In the future， a full-chain system covering syndrome differentiation， targeting， and monitoring needs to be constructed for promoting the paradigm transformation of Sishenwan into precision drugs. This review systematically explains the treatment mechanism of Sishenwan regarding the combination of disease and syndrome and its multi-target regulatory characteristics， providing a theoretical basis and transformation direction for the treatment of UC with integrated traditional Chinese and Western medicine.

Objective:To evaluate preoperative high-resolution thin-layer cervical enhanced CT used to predict the venous route of the submental flap reflux vein and its relationship with adjacent structures in order to guide the anatomical understanding and protection of submental flap in pharyngeal cancer surgery.Methods:Sixty consecutive patients with pharyngeal cancer who underwent submental flap repair surgery in our department from March 2022 to December 2024, as well as 60 patients who were accepted neck dissection suffering other cancers, were selected. Before surgery, high-resolution cervical enhanced CT scans were performed, and the position of the transverse section of the facial vein in the venous phase horizontal image gradually variation tendency was focused layer by layer. The direction and adjacent relationship of the submental flap reflux veins were determined and recorded. Combined with 60 patients with other head and neck tumors who underwent neck dissection in our department during the same period (a total of 120 cases, 240 sides), the classification and management of the draining veins of Fang′s mental flap were conducted. Type Ⅰ mainly drains into the internal jugular vein; Type Ⅱ mainly drains into the external jugular vein and Type Ⅲ mainly drains into the anterior jugular vein (often accompanied by an external jugular draining branch). The status and proportion of venous drainage were analyzed.Results:Vascular predictive coincidence rate was 98.3% (59/60) among the 60 patients with pharyngeal cancer. Only one patient was predicted to have a simple return to the external jugular vein. However, during the operation, in addition to the main return to the external jugular vein, a small portion also returned to the internal jugular vein. Submental flap reflux vessels were classified into three types based on intraoperative submental flap venous return in 60 cases of laryngopharyngeal cancer, in conjunction with the analysis of venous return patterns from 240 cervical CT scans. Type Ⅰ mainly refluxed to the internal jugular vein, accounting for 42.1%. Type Ⅱ mainly refluxed to the external jugular vein (47.9%). Type Ⅲ mainly refluxed to the anterior jugular vein (10.0%). The total detection rate of CT reading of 240 venous reflux was 98.7% (237/240). Vascular predictive coincidence rate was 97.9%(235/240).Conclusion:The detailed analysis of submental venous return vessels can accurately predict the direction of reflux veins and its surrounding areas by preoperative high-resolution enhanced CT scan. This provides reliable guidance for the anatomy and protection of the submental flap reflux veins during surgery.

Objective:To investigate the clinical efficacy of posterior midline incision combined with anteromedial approach in the treatment of complex olecranon fracture-dislocation.Methods:A retrospective analysis was performed on 26 patients (15 males and 11 females) with olecranon fracture-dislocation who were admitted from January 2020 to January 2024, including 5 cases of anterior transolecranon fracture-dislocation (2 cases of upper ulnar-radial joint dislocation), 21 cases of posterior transolecranon fracture-dislocation (5 cases of them were accompanied by upper ulnar-radial joint dislocation). Among them, there were 13 cases of traffic accidents, 7 cases of falling from heights, and 6 cases of walking falls. The average age is 45.1±15.3 years old (21-84 years old).Results:The operation time was 151.2±41.9 minutes, average tourniquet time was 93.7±22.6 minutes, and the intraoperative blood loss was 76.2±20.2 ml. The average follow-up was 16(12, 23) months, and the VAS score decreased significantly and the MEPS score increased significantly over time. At the last follow-up, the VAS score was 2(1, 2), and the MEPS score was 86.5±10.3, with 16 cases excellent, 7 cases good, and 3 cases medium, with an excellent rate of 89%. The range of motion of flexion-extension and pronation-supination were 119.3°±13.5°and 138.6°±15.2° respectively. Complications included 16 cases of ectopic ossification, of which 4 patients with significant effects on elbow function underwent surgical release 3-6 months after surgery. 1 case of ulnar nerve injury symptoms improved after emergency ulnar nerve release, and 1 case of elbow subluxation due to inaccurate coronoid process reduction and fixation. There were no serious complications such as vascular injury, internal fixation failure, fracture nonunion, and incision infection.Conclusion:The posterior midline incision combined with anteromedial approach can effectively treat complex olecranon fracture-dislocation and meet the requirements of early postoperative elbow rehabilitation.

Objective To investigate alterations in interhemispheric functional connectivity(FC)in the cerebral cortices connected via the corpus callosum in patients with Alzheimer's disease(AD),and to explore their relationships with cognitive function and activities of daily living.Methods Resting-state functional magnetic resonance imaging data were collected from 28 patients with Alzheimer's dementia(d-AD),47 patients with mild cognitive impairment(MCI),and 37 healthy controls(HC).Using a trancallosal tract template,32 pairs of homologous cortical brain regions directly connected to 32 subregions of the corpus callosum were selected as regions of interest for interhemispheric FC analysis.Further correlation analyses were performed between FC values in patient groups and their scores on the Montreal Cognitive Assessment-Basic(MoCA-B)Scale and the Activities of Daily Living(ADL)Scale.Results Compared with HC group,both MCI and d-AD groups exhibited hyperconnectivity(significantly increased FC)in interhemispheric non-homologous brain regions.Specifically,hyperconnectivity in the MCI group was scattered across the frontal,parietal,temporal,and occipital lobes,while in the d-AD group,it was concentrated within the precentral and postcentral gyri.Notably,hyperconnectivity involving the prefrontal and occipital lobes in the MCI group showed significant declines in the d-AD group.The interhemispheric homologous FC in the d-AD group reduced more significantly than the MCI group.Additionally,in the d-AD group,2 interhemispheric FC within the prefrontal lobe(between the bilateral orbital parts of the inferior frontal gyrus,and between the left medial frontal gyrus and the right middle frontal gyrus)were correlated with MoCA-B scores,and 2 FC(between the bilateral middle occipital gyri,and between the left inferior parietal lobule and the right middle frontal gyrus)were correlated with ADL scores.Conclusion MCI and d-AD exhibit distinct patterns of interhemispheric FC alterations,and the interhemispheric FC changes in AD patients are non-progressive.The close relationships between interhemispheric homologous/non-homologous FC and MoCA-B/ADL scores in d-AD patients provide an objective basis and reference for clinical neuromodulation.

Objective:To investigate the characteristics of resting-state mirror homotopic connectivity and the gray matter volume of brain in patients with neuropsychiatric systemic lupus erythematosus (NPSLE).Methods:From June 2020 to March 2023, a total of 35 NPSLE patients (NPSLE group) and 30 non-NPSLE patients (non-NPSLE group) were selected from Taizhou People's Hospital Affiliated to Nanjing Medical University, another 31 healthy volunteers were recruited as the healthy controls(HC group). All participants underwent resting-state functional magnetic resonance imaging (rs-fMRI) and mini-mental state examination (MMSE) assessments. The patients in NPSLE and non-NPSLE groups were additionally assessed using the fatigue scale for motor and cognitive functions (FSMC) and the hospital anxiety and depression scale (HADS).The DPABI V7.0 toolkit based on the MATLAB platform was used to preprocess the rs-fMRI data and calculate the voxel-mirrored homotopic connectivity(VMHC) indexes, and the differences in VMHC between groups were evaluated by covariance analysis in SPM12.0 software, and the VMHC values of brain regions with significant differences were extracted for further comparison between the two groups.Partial correlation analysis was performed to investigate the association between VMHC values and clinical parameters in NPSLE patients.The brain regions with significant differences between NPSLE patients and non-NPSLE patients were used as region of interest (ROI), and gray matter volumes within these ROIs were then calculated by VBM8 toolbox.Results:(1)There were statistically significant differences in the VMHC values of bilateral precentral gyrus, bilateral dorsolateral superior frontal gyrus, bilateral medial and paracingulate gyrus, bilateral parahippocampal gyrus, bilateral middle occipital gyrus, bilateral postcentral gyrus, and bilateral superior temporal gyrus among the 3 groups( F=11.246-14.102, all P<0.05). The NPSLE group exhibited significantly lower VMHC values in these regions compared to both the non-NPSLE group and HC group (all P<0.05), but there were no significant differences in these regions between the non-NPSLE group and HC group (all P>0.05).(2) The gray matter volumes of bilateral dorsolateral superior frontal gyrus(right: (0.57±0.11)mm 3, (0.65±0.08)mm 3, t=-3.409, P=0.001; left: (0.53±0.10)mm 3, (0.60±0.07)mm 3, t=-3.082, P=0.003), bilateral precentral gyrus(right: (0.32±0.06)mm 3, (0.35±0.04)mm 3, t=-2.044, P=0.045; left: (0.39±0.06)mm 3, (0.42±0.04)mm 3, t=-2.505, P=0.015), right medial and paracingulate gyrus((0.66±0.08)mm 3, (0.70±0.07)mm 3, t=-2.491, P=0.015) and left superior temporal gyrus((0.57±0.09)mm 3, (0.61±0.06)mm 3, t=- 2.344, P=0.022) in the NPSLE group were smaller than those of non-NPSLE group.(3)Correlation analysis showed that the VMHC value of dorsolateral superior frontal gyrus was positively correlated with IgA level in NPSLE patients ( r=0.353, P=0.047). Conclusion:Patients with NPSLE generally have decreased mirror homotopy functional connectivity in the cerebral hemispheres, accompanied by a decrease in gray matter volume in some brain regions, which can provide a certain neuroimaging basis for the pathogenesis of brain injury.

Objective:To analyze the biological parameters of the anterior segment of age-related cataracts patients with or without zonular weakness with the new generation of sweep-source anterior optical coherence tomography (OCT) device CASIA2 to provide a basis for the diagnosis of zonular weakness.Methods:A case-control study was conducted.A total of 158 cases (186 eyes) of patients with age-related cataracts having zonular weakness as a zonular weakness group, and 80 cases (80 eyes) of cataract with age-related cataracts without zonular weakness as a normal zonule group were enroll from June 2022 to June 2023 at Beijing Tongren Hospital.All patients underwent routine preoperative ophthalmological examination including slit lamp microsopy, IOLMaster 700, ocular B-ultrasound and OCT.The anterior chamber depth (ACD), anterior chamber volume (ACV), lens thickness (LT), lens vault (LV), anterior chamber angle opening distance at 750 μm (AOD750), lens decentration and tilt, radius of curvature of the anterior lens surface (RAL), and radius of curvature of the posterior lens surface (RPL) of patients were measured with CASIA2 and compared between the two groups.The relationship between zonular weakness and anterior chamber parameters and lens parameters was evaluated by logistic regression analysis.This study followed the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Beijing Tongren Hospital (No.TRECKY2018-049), and all enrolled patients signed the informed consent form.Results:In the zonular weakness group, ACD, ACV, RAL, and AOD750 were (2.34±0.56)mm, (85.05±40.19)mm 3, 7.52 (7.13, 8.08)mm, and 0.27 (0.07, 0.30)mm, respectively, which were smaller than (3.13±0.38)mm, (127.75±38.15)mm 3, 9.28(8.51, 9.76)mm, and 0.52 (0.31, 0.65)mm in the normal zonule group, with statistically significant differences (all P<0.05).LT and LV in the zonular weakness group were (5.14±0.45)mm and (1.22±0.53)mm, respectively, which were larger than (4.27±0.52)mm and (0.32±0.30)mm in the normal zonule group, and the differences were statistically significant (both P<0.05).Magnitude of lens decentration and tilt in the zonular weakness were 0.34 (0.13, 0.45)mm and 6.44 (3.67, 7.32)°, respectively, which were significantly larger than 0.19 (0.12, 0.25)mm and 4.88 (3.85, 5.65)° in the normal zonule group (both P<0.05).No obvious pattern was found in the direction of decentration and tilt.Logistic regression analysis showed that LV and lens decentration were risk factors of zonular weakness (odds ratios [ OR]=706.170, 335.339; both P<0.05), and RAL was a protective factor of zonular weakness ( OR=0.239, P<0.05). Conclusions:Age-related cataract patients with zonular weakness often present with a decrease in ACV due to increased anterior convexity of the lens.Decreased RAL, increased lens decentration and elevated LV are risk factors for zonular weakness.

Objective:To observe the effect of intravenous human immunoglobulin (pH4) (IVIg) on total immunoglobulin (Ig) levels in patients with B-cell non-Hodgkin lymphoma (NHL) and to evaluate its clinical efficacy in ameliorating hypogammaglobulinemia following CD20 monoclonal antibody therapy.Methods:Clinical data of 98 patients with B-cell NHL who developed hypogammaglobulinemia after CD20 monoclonal antibody therapy and were hospitalized in the Department of Hematology, The First Affiliated Hospital of Soochow University, from January 2018 to June 2022, were retrospectively analyzed. Patients were divided into the IVIg group ( n=70) and the conventional treatment group ( n=28). To exclude the interference of plasma transfusion on total Ig levels, statistical analysis was performed on the IVIg group without plasma transfusion ( n=53) and the conventional treatment group ( n=25). The therapeutic efficacy of IVIg was analyzed by observing its effect on elevating total Ig levels and the duration of this effect. The infection control efficacy of IVIg was assessed by comparing other blood biochemical parameters. The safety of IVIg in clinical application was also evaluated. Results:In the IVIg group, the mean total Ig level within 1-3 days after IVIg treatment was (20.67±4.17) g/L, significantly higher than the pre-treatment level of (17.16±1.76) g/L ( P<0.001). In 22 patients from the IVIg group, total Ig levels at 1-7 days, 8-14 days, and 15-30 days post-treatment were all significantly different compared to pre-treatment levels (all P<0.001). In the conventional treatment group, the mean total Ig level within 1-3 days after hospitalization showed no significant difference compared to the level at admission [ (18.12±1.84) g/L vs (18.43±1.79) g/L, P>0.05]. The proportion of patients in the IVIg group whose total Ig level reached 20 g/L within 1-3 days post-IVIg treatment was significantly higher than that in the conventional treatment group within 1-3 days after admission (57.69% vs 0, P<0.001). In 12 patients from the IVIg group with baseline neutrophil levels below normal, neutrophil levels at 1-3 days, 4-7 days, and 8-14 days post-treatment were significantly increased compared to pre-treatment levels (all P<0.05). The proportion of patients with new-onset infections post-treatment was lower in the IVIg group (22.64%, 12/53) than in the conventional treatment group (36.00%, 9/25), although the difference was not statistically significant ( P>0.05). Among 70 patients in the IVIg group, 8 patients experienced grade 1-2 adverse reactions, including nausea and vomiting in 5 patients, rash in 2 patients, and muscle/joint pain in 1 patient. No grade 3 or higher adverse reactions were observed. Conclusion:IVIg increased Ig and neutrophil levels in patients with B-cell NHL after CD20 monoclonal antibody therapy and may play a role in controlling new-onset infections. IVIg is effective and safe for treating hypogammaglobulinemia secondary to CD20 monoclonal antibody therapy in patients with B-cell NHL.

Objective:To investigate the diagnostic potential of serum Dickkopf-related protein 3(Dkk3)as a novel biomarker for sarcopenia in an elderly Chinese population by examining its correlation with muscle mass, muscle strength, and physical function.Methods:The study included elderly individuals aged ≥60 years from the Health Examination Center of Jiangsu Provincial Hospital between 2021 and 2022, who had independent mobility and were free from acute diseases.Fat and muscle mass were measured using Dual-energy X-ray Absorptiometry(DXA). Grip strength and chair stand test times were employed to assess upper and lower limb muscle strength, respectively.Physical function was evaluated using the Short Physical Performance Battery(SPPB). Serum Dkk3 concentration was measured using a human Dkk3 enzyme-linked immunosorbent assay(ELISA)kit.Results:A total of 108 elderly participants(83 males)were included in the study, with an age range of 60 to 97 years(mean age: 70.6±10.8). Serum Dkk3 concentration was found to be negatively correlated with the skeletal muscle mass index(SMI)( R=-0.292, P=0.002), lower limb muscle mass( R=-0.320, P<0.001), upper limb muscle mass( R=-0.222, P=0.020), and hip muscle mass( R=-0.261, P=0.006). Functional assessments revealed negative correlations with grip strength( R=-0.204, P=0.035), 4-meter walking speed( R=-0.195, P=0.043), the three-position balance test( R=-0.245, P=0.011), and the SPPB score( R=-0.196, P=0.043). Regression analysis indicated that, after adjusting for age, sex, body mass index(BMI), and comorbidities, Dkk3 remained negatively associated with lower limb muscle mass( β=-0.197, P=0.012), hip muscle mass( β=-0.156, P=0.029), and the SPPB score( β=-0.001, P=0.013). The sarcopenia group exhibited a 55.6% higher serum Dkk3 level compared to the control group(76.68±37.62 ng/ml vs.49.27±25.88 ng/ml, P<0.001). Receiver Operating Characteristic(ROC)curve analysis determined the optimal diagnostic threshold to be 80.08 ng/ml, with an area under the curve of 0.726, a sensitivity of 41.98%, and a specificity of 96.30% for detecting sarcopenia. Conclusions:Serum Dkk3 is closely associated with reduced muscle mass in the lower limbs and hips, as well as a decline in physical function, in elderly individuals with sarcopenia.Given its cost-effectiveness and clinical utility, serum Dkk3 shows potential as a meaningful biomarker for diagnosing sarcopenia in the elderly.
