Objective: To investigate the efficacy，safety and feasibility of regional lymph node dissection in laparoscopic radical surgery for bladder cancer under the guidance of indocyanine green fluorescence imaging. Methods: A total of 30 patients with muscle invasive bladder cancer (T2/T3NxM0) who volunteered to enter the clinical trial were randomly divided into the indocyanine green imaging guided laparoscopic regional lymph node dissection group (n=15) and the standard pelvic lymph node dissection group (n=15).The number of positive lymph nodes，operation time，intraoperative bleeding volume，incidence of lymph leakage，and tumor recurrence and metastasis rate 2-year after surgery were collected. Results: The number of positive lymph nodes was (4.20±1.66) and (4.60±1.72) respectively in the indocyanine green and standard groups，with no statistically significant difference (P>0.05).There were no statistically significant difference in the tumor recurrence and metastasis rates 2-year after surgery between the two groups (P>0.05).However，the indocyanine green group had shorter operation time，less intraoperative bleeding volume，and lower incidence of lymphatic leakage than the standard group (P<0.05). Conclusion: Indocyanine green fluorescence imaging guided laparoscopic lymph node dissection has comparable clinical efficacy to standard lymph node dissection，but with fewer complications.

Osteosarcopenia is a geriatric syndrome referring to the co-existence of osteoporosis and sarcopenia.Its pathogenesis involves factors such as genetics, mechanics of the musculoskeletal system, endocrine regulatory mechanisms and molecular signaling pathways.In clinical practice, aside from comprehensive assessment of risk factors, screening of bone density, muscle strength, muscle mass and the overall body function must also be undertaken.Intervention measures primarily include therapeutic exercise, nutritional support and drugs.

Adenosine has been proved to have immunosuppressive effect in many different diseases, and the activity of ecto-5’-nucleotidase(CD73) on the cell surface is the rate-limiting step of extracellular adenosine production. CD73 has a profound and lasting impact on tumor immune regulation of regulatory T cells, B cells, macrophages and natural killer cells. CD73-mediated adenosine pathway is significant in signal transduction during cancer progression in tumor microenvironment, making CD73 a novel immune checkpoint. Therefore, CD73 inhibition is a emergent and promising strategy for cancer immunotherapy. At present, a variety of monoclonal antibodies and small molecule inhibitors have been in clinical development. This review comprehensively summarizes the frontier research progress of reported small molecule CD73 inhibitors, which can provide guidance for the investigation of novel CD73 inhibitors for cancer therapy.

OBJECTIVE To evaluate the quality and existing problems of Compound Paracetamol and Chlorphenamine Tablets for Infant. METHODS Using legal standards to inspect sampled samples, and several analytical methods were subsequently established or improved for the exploratory research on related substances, assay, dissolution, subdivision characteristics of scored tablets, and genotoxic impurities. RESULTS All samples met the regulatory specification, and the pass rate was 100%. However, the control for related substances was lacking, and the method for assay and content uniformity was defective. The exploratory studies showed that the assay and content uniformity met the requirements, and the risk of related substances and genotoxic impurities was acceptable. As a divisible tablet, the subdivision characteristics could not meet the requirements of the scored tablet, and the dissolution performance of some enterprise samples could not meet the requirements of similar products in foreign pharmacopoeias. CONCLUSION The overall quality of this product is adequate. However, due to the early time on the market, some quality attributes no longer meet the requirements of current regulations or relevant guidelines. The manufacturers should further optimize the prescription and production process, referring to foreign similar products. The current specification needs to be revised and improved.

Objective To compare the clinical efficacy of peritoneolaparoscopic single position nephreteral total length resection(PSPNTLR)and posterior laparoscopic subabdominal incision technique(PLSIT)in the treatment of upper urothelial carcinoma(UTUC).Methods A total of 82 UTUC patients treated in our hospital during Jan.2018 and Feb.2021 were divided into the observation group(n=41,treated with PSPNTLR)and control group(n=41,treated with PLSIT)according to the random number table method.Perioperative indicators,pain degree,inflammatory factors,bladder recurrence and distant metastasis were compared between the two groups.Results The operation time[(122.15±15.14)min vs.(160.88±17.26)min],hospitalization time[(10.07±2.14)d vs.(12.22±3.13)d]and postoperative exhaust time[(1.46±0.57)d vs.(3.10±0.88)d]were significantly shorter,the intraoperative blood loss[(42.85±4.88)mL vs.(78.22±8.17)mL]and drainage volume[(53.61±9.74)mL vs.(81.56±11.06)mL]were significantly less in the observation group than in the control group(P＜0.05).The visual analogue score(VAS)of the observation group at 6,12 and 24 h after operation was significantly lower than that of the control group(P＜0.05).The levels of interleukin-6(IL-6)and C-reactive protein(CRP)were increased in both groups one day after surgery,but the indexes were increased more significantly in the control group(P＜0.05).During the 2-year follow-up after surgery,there were no statistical difference in bladder recurrence(12.20％vs.14.63％)and distant metastasis(9.76％vs.4.88％)between the two groups(P＞0.05).Conclusion Both PSPNTLR and PLSIT have good therapeutic safety,but PSPNTLR is more effective in improving perioperative indicators,reducing postoperative pain,and inhibiting inflammatory factors.

Objective To investigate the efficacy,safety and feasibility of laparoscopic lymph node dissection guided by indocyanine green(ICG)fluorescence imaging.Methods A total of 30 patients with muscle-invasive bladder cancer(MIBC,T2/T3NxM0)who were admitled to the Cangzhou People's Hospital during Mar.2018 and Jun.2022 were included.The lymph nodes were cleared with ICG fluorescence imaging first,and then the remaining lymph nodes were cleared according to the standard pelvic lymph node range.The lymph node positive rate of ICG fluorescence imaging guided laparoscopic lymph node precise dissection and standard pelvic lymph node dissection was analyzed by self-comparison.Results ICG fluorescence imaging guided laparoscopic lymph node precise dissection needed shorter operation time than standard pelvic lymph node dissection[(21.80±6.80)min vs.(47.70±10.73)min,P＜0.05].There was no significant difference in the lymph node positive rate between the two approaches[(11.34±9.06)％vs.(12.36±9.43)％,P＞0.05],but the former approach caused less damage on blood vessels and nerves.Conclusion Indocyanine green fluorescence imaging guided laparoscopic lymph node dissection has comparable efficacy to standard pelvic lymph node dissection,which can reduce ineffective lymph node dissection,shorten the operation time,and reduce the risk of complications.

Objective:To explore the diagnostic value of serum C-C chemokine ligand 5 (CCL5) in assessing the degree of liver fibrosis in patients with metabolic-associated fatty liver disease (MAFLD).Methods:71 MAFLD patients who visited the Department of Integrated Traditional and Western Medical Hepatology, Third Hospital of Hebei Medical University, and underwent liver biopsy histopathology examinations between October 2021 and June 2023 were selected for diagnostic testing. Simultaneously, 71 healthy subjects who underwent physical examinations at the physical examination center of the hospital were selected as the control group. Serum CCL5 levels were detected using an enzyme-linked immunosorbent assay (ELISA). Routine blood tests, liver and kidney function tests, and other tests were conducted to analyze the expression level of CCL5 and its correlation with the above indicators. The aspartate aminotransferase/platelet ratio index (APRI) and fibrosis 4 index (FIB-4) were calculated. SPSS 26.0 software was used for statistical analysis. The area under the receiver operating characteristic curve (ROC) was used to evaluate the diagnostic efficacy of CCL5 for the degree of liver fibrosis in MAFLD. The combined diagnostic efficacy of APRI and FIB-4 was further analyzed for the degree of liver fibrosis in MAFLD.Results:The expression level of serum CCL5 gradually increased with the increase in liver fibrosis stage in patients with MAFLD, and the difference was statistically significant ( P<0.05). The AUC value of serum CCL5 for diagnosing significant liver fibrosis in MAFLD patients was 0.775, with a sensitivity of 65.7%, a specificity of 80.6%, and an optimal cutoff value of 49.845 ng/ml. The CCL5 and FIB-4 combination had the highest diagnostic value for significant liver fibrosis in patients with MAFLD, with an AUC of 0.802, a sensitivity of 91.4%, and a specificity of 61.1%. Conclusion:CCL5 has a high diagnostic value for significant liver fibrosis in MAFLD patients. Therefore, it is expected to become a non-invasive diagnostic marker for assessing the degree of liver fibrosis in MAFLD patients.

Objective:To investigate the therapeutic impact of combining vitamin D supplementation with dietary adjustments on elderly male patients with diabetes and osteosarcopenia.Methods:From January 2021 to May 2023, a total of 108 male patients diagnosed with diabetes and osteosarcopenia were admitted to Beijing hospital for research purposes.The patients were randomly assigned to either a control group( n=54)or a trial group( n=54).The control group received conventional dietary adjustments, while the trial group received vitamin D supplementation in addition to dietary adjustments.Various parameters including 25-(OH)-VitD 3 levels, blood glucose levels, appendicular skeletal muscle mass index(ASMI), bone mineral density, and bone metabolism indexes were measured before and after the treatment in both groups. Results:Compared to the pre-treatment period, the levels of 25-(OH)-VitD 3, grip strength, 6 m step speed, and ASMI increased in both groups, while fasting blood glucose and 2 h postprandial blood glucose decreased significantly(all P<0.05).Additionally, the experimental group showed higher levels of 25-(OH)-VitD 3, grip strength, 6 m step speed, and ASMI compared to the control group post-treatment, with lower levels of fasting blood glucose and 2 h postprandial blood glucose(all P<0.05).Compared with the pre-treatment period (bone density values in the lumbar spine: 0.41±0.09, the hip: 0.42±0.12 in the control group; bone density values in the lumbar spine: 0.43±0.07, the hip: 0.44±0.09 in the experimental group), the bone density values of the lumbar spine and the hip were higher in both groups after treatment(bone density values in the lumbar spine: 0.76±0.12, the hip: 0.78±0.12 in the control group; bone density values in the lumbar spine: 0.95±0.22, the hip: 0.97±0.28 in the experimental group). The bone density values of the lumbar spine and the hip in the experimental group were higher than those of the control group after treatment(all P<0.05).Furthermore, serum concentrations of parathyroid hormone(PTH)and osteoclast differentiation factor(RANKL)were significantly lower, while serum osteocalcin(OCN)was significantly higher in both groups post-treatment(all P<0.05).In the experimental group, serum PTH and RANKL concentrations were significantly lower and serum OCN was significantly higher compared to the control group post-treatment(all P<0.05). Conclusions:The results show that incorporating vitamin D into dietary changes can effectively regulate blood glucose levels, decrease bone loss, enhance bone density, and improve muscle quality in this patient population.

Mild traumatic brain injury (mTBI) is a traumatic disease that has transient impairment of consciousness and memory function after an external force to the head with basically normal neurological function and neuroimaging examination results. At present, research on mTBI is insufficient, resulting from early diagnosed difficulty of mTBI patients (due to mild clinical manifestations) and not suitable traditional diagnosis and treatment evaluation methods. This article reviews the research progress in the pathogenesis, auxiliary examinations, treatment principles and related diseases of mTBI, aiming to provide new theoretical basis for diagnosis and treatment of mTBI.
