Based on spleen deficiency-phlegm dampness as the core pathogenesis of obesity， and integrating recent advances in modern medicine regarding the key role of immune inflammation in obesity， this paper proposes a multidimensional pathogenic network of "obesity-spleen deficiency-phlegm dampness-immune imbalance". Various traditional Chinese medicine （TCM） herbs that strengthen the spleen， regulate qi， and resolve phlegm and dampness can treat obesity by improving spleen-stomach transport and transformation， promoting water-damp metabolism， and regulating immune homeostasis. This highlights immune inflammation as an important entry point to elucidate the TCM concepts of "spleen deficiency-phlegm dampness" and the therapeutic principle of "strengthening the spleen and eliminating dampness to treat obesity". By systematically analyzing the intrinsic connection between "spleen deficiency generating dampness， internal accumulation of phlegm dampness" and immune dysregulation in obesity， this paper aims to provide theoretical support for TCM treatment of obesity based on dampness.

Sleep disorders have a high incidence rate in patients with end-stage renal disease(ESRD)and severely affect their quality of life.As the most effective treatment for ESRD,kidney transplantation can significantly improve renal function and prolong survival of patients.However,clinical observations have found that 19.3%to 78.0%of kidney transplant recipients still experience persistent various sleep disorders,such as insomnia,sleep-related breathing disorders and sleep-related movement disorders after surgery.These sleep disorders not only lead to impaired daytime function but are also closely related to adverse outcomes such as cardiovascular complications and increased infection risks.Currently,research on the pathogenesis of sleep disorders in kidney transplant recipients is still insufficient,and clinical diagnosis and treatment face many challenges.This article systematically reviews the epidemiological characteristics,pathophysiological mechanisms,clinical impacts,and new developments in the diagnosis and treatment of sleep disorders in kidney transplant recipients.It aims to provide evidence-based support for clinicians and promote the establishment of more comprehensive early screening and individualized treatment plans to improve the long-term prognosis of recipients.

Objective:To explore the clinical characteristics and prognostic factors of primary bladder adenocarcinoma（ACB）.Methods:The clinical data of 33 patients with primary ACB who underwent surgical treatment in the Department of Urology of Peking University Third Hospital from July 2003 to January 2024 were retrospectively analyzed. There were 5 females and 28 males，with an average age of（61.3 ± 11.5）years. Twelve patients had comorbidities（6 hypertension，2 coronary heart disease，5 diabetes mellitus，and 3 cerebrovascular diseases）and 12 had a smoking history. The mean body mass index（BMI）was（24.8 ± 3.2）kg/m 2. The maximum tumor diameter measured by enhanced computed tomography（CT）was（29.7 ± 12.7）mm. The preoperative neutrophil-to-lymphocyte ratio（NLR）was 3.4 ± 3.2，and the systemic immune-inflammation index（SII）was（582 ± 496）× 10 9/L.Patients were divided into two groups according to the surgical approach：the radical cystectomy group（ n = 23）and the bladder-sparing group（ n = 10）. For the radical cystectomy group，there were 19 males and 4 females，with a mean age of（59.9 ± 12.6）years. Five patients had comorbidities（3 hypertension，1 coronary heart disease，1 diabetes mellitus，and 2 cerebrovascular diseases）. Eight patients had a smoking history，with a mean BMI of（25.2 ± 3.5）kg/m 2. The maximum tumor diameter was（33.6 ± 10.9）mm，the preoperative NLR was 3.5 ± 3.5，and the SII was（618 ± 558）× 10 9/L. For the bladder-sparing group，there were 9 males and 1 female，with a mean age of（64.5 ± 8.2）years. Seven patients had comorbidities（3 hypertension，1 coronary heart disease，4 diabetes mellitus，and 1 cerebrovascular diseases）. Four patients had a smoking history，with a mean BMI of（23.5 ± 2.3）kg/m 2. The maximum tumor diameter was（20.7 ± 12.5）mm，the preoperative NLR was 3.1 ± 2.2，and the SII was（501 ± 323）× 10 9/L. Statistically significant differences were observed between the two groups in terms of comorbidities（ P = 0.008）and maximum tumor diameter（ P = 0.006），while no significant differences were found in other data（ P > 0.05）. The Kaplan-Meier survival curve was drawn，and Cox regression was used to analyze the prognostic factors of progression-free survival（PFS）and overall survival（OS）of patients. Results:Among the 33 patients，low-grade adenocarcinoma and high-grade adenocarcinoma accounted for 60.6% and 39.4% respectively according to the postoperative pathology，and 3 patients had positive surgical margins. There were 22 cases of muscle-invasive bladder adenocarcinoma，5 cases of lymph node metastasis，and 1 case of distant metastasis. The patients in tumor stages Ⅰ—Ⅳ were 9 cases（27.3%），8 cases（24.2%），7 cases（21.2%），and 9 cases（27.3%）respectively. Nine patients received postoperative adjuvant therapy，including 6 with adjuvant chemotherapy，2 with adjuvant chemotherapy combined with radiotherapy，and 1 with adjuvant immunotherapy. In the radical cystectomy group（ n = 23），there were 13 cases of low-grade and 10 cases of high-grade pathological grading，2 cases with positive margins，19 cases of muscle-invasive bladder adenocarcinoma，5 cases of lymph node metastasis，1 case of distant metastasis，and 5 patients received adjuvant therapy（4 cases of adjuvant chemotherapy，and 1 case of adjuvant immunotherapy）. In the bladder-sparing group（ n = 10），there were 7 cases of low-grade，3 cases of high-grade pathological grading，1 case with positive margins，3 cases of muscle-invasive bladder adenocarcinoma，zero lymph node or distant metastasis，and 4 patients received adjuvant therapy（2 cases of adjuvant chemotherapy，and 2 cases of combined adjuvant chemotherapy and radiotherapy）. A statistically significant difference was found in the proportion of muscle-invasive bladder adenocarcinoma between the two groups（ P = 0.006），while no significant differences were observed in other data（ P > 0.05）.The median follow-up duration of the patients was 28.0 months，the median PFS was 86.0 months，and the median OS was 90.0 months. The 2-year PFS and OS were 65.4% and 73.1% respectively. The 5-year PFS and OS were 54.2% and 56.5% respectively. The Kaplan-Meier survival analysis showed that there were no significant differences in PFS（ P = 0.777）and OS（ P = 0.585）between the radical cystectomy group and the bladder-preserving group. Female（ P = 0.011），BMI < 25 kg/m2（ P = 0.038），and positive surgical margins（ P < 0.01）were associated with poorer PFS. Aged ≥ 70 years（ P = 0.003），lymph node metastasis（ P = 0.041），and positive surgical margins（ P = 0.025）were associated with poorer OS，and patients in the adjuvant therapy group had better OS（ P = 0.005）. Multivariate Cox regression analysis indicated that positive surgical margins（HR 10.2， P = 0.012）were an independent impact factor for PFS，and positive surgical margins（HR 39.8， P = 0.001）and adjuvant therapy（HR 0.12， P = 0.021）were independent impact factors for OS. Conclusions:Positive surgical margins and adjuvant therapy are independent impact factors for the prognosis of patients with primary ACB.

Objective:To investigate the effects of repetitive transcranial magnetic stimulation(rTMS) on learning memory and abnormal Aβ deposition in cerebral amyloid angiopathy(CAA) model mice, and further to investigate whether the mechanism involves the transport function of glymphatic system.Methods:Eight-month-old SPF grade Tg-SWDI mice were randomly divided into the CAA group and the rTMS group according to the random number table method with 7 in each group.Seven wild-type mice of the same genetic background and age served as the control group. The mice in rTMS group received two weeks of high-frequency rTMS intervention, and the mice in CAA group and control group were only restrained without rTMS intervention.Learning and memory functions were evaluated using the Morris water maze test.Amyloid-beta deposition, glymphatic system clearance, and aquaporin-4(AQP4) polarization were assessed using immunofluorescence, and AQP4 expression levels were measured by Western blot.Statistical analysis of the data was conducted using SPSS 25.0 and GraphPad Prism 9.5 softwares.Repeated-measures ANOVA was used for data on escape latency, and one-way ANOVA was used for comparisons between multiple groups for other data.Results:(1)In the novel object recognition test, there were statistically significant differences in recognition indices among the three groups of mice ( F=22.59, P<0.05). Compared with the control group, the mice in the CAA group showed a significant decrease in the new object recognition index ( P<0.05).Compared with the CAA group, the mice in the rTMS group showed a significant increase in the new object recognition index ( P<0.05).(2)In the Y-maze, there were statistical differences in the spontaneous alternation rates among the three groups ( F=5.00, P<0.05). Compared with the control group, the spontaneous alternation rate in the CAA group was significantly lower ( P<0.05).And compared with the CAA group, the spontaneous alternation rate in the rTMS group was significantly higher ( P<0.05).(3)In the Morris water maze test, there were significant interactions in escape latency among the three groups ( F=4.05, P=0.02), significant main effects of time ( F=713.22, P<0.01), and significant main effects of group ( F=421.55, P<0.01). There was no significant statistical difference in swimming speed among the three groups ( F=0.19, P>0.05), while the difference of the number of entries into the inner zone and the proportion of time spent were statistically significant( F=71.67, 294.14, both P<0.05).Compared with the control group, the CAA group mice significantly decreased in the number of entries into the inner zone and the proportion of time spent in the middle zone (both P<0.01).(4)Compared with the CAA group, the rTMS group significantly increased in the number of entries into the inner zone and the proportion of time spent in the middle zone (both P<0.01).The result of immunofluorescence test showed that there was a statistically significant difference in the levels of Aβ in the cerebral vessels among the three groups( F=385.76, P<0.01).The levels of Aβ in the cerebral vessels of the CAA group (62.00±2.65) were significantly higher than those in the control group (9.00±1.00, P<0.01).The levels in the rTMS group (51.33±3.21) were significantly lower than those in the CAA group (62.00±2.65, P<0.01). Using the residual fluorescence tracer levels of the control group as a baseline, there were statistically significant differences in the tracer intensities in the corpus callosum and cerebral cortex( F=258.97, 46.44, both P<0.05), the tracer intensities in the corpus callosum (3.57±0.21) and cerebral cortex (4.96±0.79) of the CAA group mice were significantly higher than those in the rTMS group (1.45±0.14, 1.78±0.47, P<0.01). The polarization of AQP4 in the cerebral cortex of rTMS group (0.51±0.07) was significantly higher than that in the CAA group (0.30±0.02, P<0.01). Conclusion:rTMS can alleviate learning memory and abnormal Aβ deposition in CAA model mice by modulating AQP4 polarisation and promoting transport function of glymphatic system.

In traditional Chinese medicine(TCM)clinical practice,nocturia is usually treated from the perspective of regulating the kidney and bladder.After analyzing the zang-fu organ extraordinary connection theory proposed by Li Chan,an physician in Ming Dynasty,which highlights the extraordinary connection of qi between the kidney and triple energizer as well as the lung and bladder,this article proposes that the pathogenesis of nocturia can be summarized accordingly as"deficiency-cold of lung qi failing in warming and then leading to the disordered opening and closing of bladder,"and"decline of vital gate fire in the kidney resulting in the disordered qi transformation of the triple energizer".The treatment of nocturia can be conducted by warming lung and transforming qi to regulate bladder function with the modified use of Gancao Ganjiang Decoction plus Suoquan Pills,or by tonifying kidney and warming yang to promote triple-energizer qi transformation with the modified use of Jingui Shenqi Pills.The differentiation and treatment of nocturia guided by the zang-fu organ extraordinary connection theory expands the understanding of its pathogenesis and treatment approaches,and will provide new ideas for its clinical practice.

Renal cell carcinoma(RCC)is a highly aggressive malignant tumor,for which traditional 18F-FDG positron emission computed tomography/computed tomography(PET/CT)exhibits insufficient sensitivity in diagnosing primary lesions.This article reviews the recent advances in novel PET/CT tracers for the diagnosis and treatment of RCC,focusing on tracers targeting carbonic anhydrase Ⅸ(CAⅨ),prostate-specific membrane antigen(PSMA),fibroblast activation protein(FAP),somatostatin receptor(SSTR),and C-methionine(c-MET).This article aims to provide reference for the early diagnosis and optimization of treatment strategies for RCC,so as to drive innovations in the field of oncologic imaging.These novel tracers demonstrate significant advantages in improving the sensitivity and specificity of detecting primary and metastatic RCC lesions,as well as in assessing treatment response,thereby addressing the limitations of traditional 18F-FDG PET/CT.Although these novel PET/CT tracers show great potential in the diagnosis and treatment of RCC,their efficacy and safety require further validation through large-scale trials.In the future,the development of multi-target tracers combined with artificial intelligence is expected to achieve precise diagnosis and individualized treatment of RCC.

The polarization of AQP4 in the cerebral cortex of rTMS group (0.51±0.07) was significantly higher than that in the CAA group (0.30±0.02, P<0.01). Conclusion:rTMS can alleviate learning memory and abnormal Aβ deposition in CAA model mice by modulating AQP4 polarisation and promoting transport function of glymphatic system.

Objective To establish a combined model of spectral CT multi-parameters and clinical features to distinguish between gastric poorly cohesive carcinoma and tubular adenocarcinoma.Methods A total of 87 patients with gastric cancer confirmed by postoperative pathology were retrospectively selected,including 26 patients with poorly cohesive carcinoma and 61 patients with tubular adenocarcinoma.Predictors were identified by univariate and multivariate logistic regression analyses,and a combined model was established.The area under the curve(AUC)of receiver operating characteristic(ROC)curve was used to evaluate the differential diagnostic efficiency of the parameters and the model.The AUC was compared by DeLong method.Results The gender[odds ratio(OR)5.124,P=0.004],normalized iodine density in the arterial phase(nIoDAP)(OR 5.789,P=0.017),arterial enhancement fraction(AEF)(OR 7.007,P=0.002)and ΔIoD(OR 0.025,P=0.021)were identified as independent predictors for poorly cohesive carcinoma by logistic regression analysis.The AUC of combined model established by four variables in distinguishing poorly cohesive carcinoma and tubular adenocarcinoma was 0.837[95％confidence interval(CI)0.716-0.907],which was significantly higher than that of single tumor spectral CT parameters(P＜0.01).Conclusion The combined model based on patients'gender and tumor spectral CT parameters(nIoDAP,AEF and ΔIoD)can effectively distinguish gastric poorly cohesive carcinoma and tubular adenocarcinoma,providing a basis for gastric cancer patients'individualized treatment strategy.

Objective:To explore the clinical characteristics and prognostic factors of primary bladder adenocarcinoma（ACB）.Methods:The clinical data of 33 patients with primary ACB who underwent surgical treatment in the Department of Urology of Peking University Third Hospital from July 2003 to January 2024 were retrospectively analyzed. There were 5 females and 28 males，with an average age of（61.3 ± 11.5）years. Twelve patients had comorbidities（6 hypertension，2 coronary heart disease，5 diabetes mellitus，and 3 cerebrovascular diseases）and 12 had a smoking history. The mean body mass index（BMI）was（24.8 ± 3.2）kg/m 2. The maximum tumor diameter measured by enhanced computed tomography（CT）was（29.7 ± 12.7）mm. The preoperative neutrophil-to-lymphocyte ratio（NLR）was 3.4 ± 3.2，and the systemic immune-inflammation index（SII）was（582 ± 496）× 10 9/L.Patients were divided into two groups according to the surgical approach：the radical cystectomy group（ n = 23）and the bladder-sparing group（ n = 10）. For the radical cystectomy group，there were 19 males and 4 females，with a mean age of（59.9 ± 12.6）years. Five patients had comorbidities（3 hypertension，1 coronary heart disease，1 diabetes mellitus，and 2 cerebrovascular diseases）. Eight patients had a smoking history，with a mean BMI of（25.2 ± 3.5）kg/m 2. The maximum tumor diameter was（33.6 ± 10.9）mm，the preoperative NLR was 3.5 ± 3.5，and the SII was（618 ± 558）× 10 9/L. For the bladder-sparing group，there were 9 males and 1 female，with a mean age of（64.5 ± 8.2）years. Seven patients had comorbidities（3 hypertension，1 coronary heart disease，4 diabetes mellitus，and 1 cerebrovascular diseases）. Four patients had a smoking history，with a mean BMI of（23.5 ± 2.3）kg/m 2. The maximum tumor diameter was（20.7 ± 12.5）mm，the preoperative NLR was 3.1 ± 2.2，and the SII was（501 ± 323）× 10 9/L. Statistically significant differences were observed between the two groups in terms of comorbidities（ P = 0.008）and maximum tumor diameter（ P = 0.006），while no significant differences were found in other data（ P > 0.05）. The Kaplan-Meier survival curve was drawn，and Cox regression was used to analyze the prognostic factors of progression-free survival（PFS）and overall survival（OS）of patients. Results:Among the 33 patients，low-grade adenocarcinoma and high-grade adenocarcinoma accounted for 60.6% and 39.4% respectively according to the postoperative pathology，and 3 patients had positive surgical margins. There were 22 cases of muscle-invasive bladder adenocarcinoma，5 cases of lymph node metastasis，and 1 case of distant metastasis. The patients in tumor stages Ⅰ—Ⅳ were 9 cases（27.3%），8 cases（24.2%），7 cases（21.2%），and 9 cases（27.3%）respectively. Nine patients received postoperative adjuvant therapy，including 6 with adjuvant chemotherapy，2 with adjuvant chemotherapy combined with radiotherapy，and 1 with adjuvant immunotherapy. In the radical cystectomy group（ n = 23），there were 13 cases of low-grade and 10 cases of high-grade pathological grading，2 cases with positive margins，19 cases of muscle-invasive bladder adenocarcinoma，5 cases of lymph node metastasis，1 case of distant metastasis，and 5 patients received adjuvant therapy（4 cases of adjuvant chemotherapy，and 1 case of adjuvant immunotherapy）. In the bladder-sparing group（ n = 10），there were 7 cases of low-grade，3 cases of high-grade pathological grading，1 case with positive margins，3 cases of muscle-invasive bladder adenocarcinoma，zero lymph node or distant metastasis，and 4 patients received adjuvant therapy（2 cases of adjuvant chemotherapy，and 2 cases of combined adjuvant chemotherapy and radiotherapy）. A statistically significant difference was found in the proportion of muscle-invasive bladder adenocarcinoma between the two groups（ P = 0.006），while no significant differences were observed in other data（ P > 0.05）.The median follow-up duration of the patients was 28.0 months，the median PFS was 86.0 months，and the median OS was 90.0 months. The 2-year PFS and OS were 65.4% and 73.1% respectively. The 5-year PFS and OS were 54.2% and 56.5% respectively. The Kaplan-Meier survival analysis showed that there were no significant differences in PFS（ P = 0.777）and OS（ P = 0.585）between the radical cystectomy group and the bladder-preserving group. Female（ P = 0.011），BMI < 25 kg/m2（ P = 0.038），and positive surgical margins（ P < 0.01）were associated with poorer PFS. Aged ≥ 70 years（ P = 0.003），lymph node metastasis（ P = 0.041），and positive surgical margins（ P = 0.025）were associated with poorer OS，and patients in the adjuvant therapy group had better OS（ P = 0.005）. Multivariate Cox regression analysis indicated that positive surgical margins（HR 10.2， P = 0.012）were an independent impact factor for PFS，and positive surgical margins（HR 39.8， P = 0.001）and adjuvant therapy（HR 0.12， P = 0.021）were independent impact factors for OS. Conclusions:Positive surgical margins and adjuvant therapy are independent impact factors for the prognosis of patients with primary ACB.
