Objective:To evaluate the effectiveness of splenic circulation control technology in minimally invasive radical resection surgery for pancreatic neck/body cancer.Methods:This is a retrospective case series study. Retrospective analysis of clinical data of 12 patients who underwent laparoscopic or robotic radical resection for pancreatic neck/body cancer at the Department of Gastrointestinal and Pancreatic Surgery,Zhejiang Provincial People′s Hospital between January 2024 and January 2025. There were 7 males and 5 females,with mean age of 68 years (range: 52 to 79 years). Clinical data including preoperative,intra-operative and postoperative outcomes were analyzed. Postoperative follow-up was conducted via outpatient visits and telephone interviews,with the follow-up ending on April 1,2025.Results:All 12 patients underwent minimally invasive radical resection of pancreatic neck/body cancer using splenic circulation control technology,consisted of 3 laparoscopic and 9 robotic procedures. The mean operative time was 185 minutes (range: 140 to 315 minutes),and the average blood loss was 100 ml (range: 30 to 300 ml). Two cases involved combined organ resection.There was no conversion to open surgery. Postoperative complications were observed in 2 patients. One patient developed grade B pancreatic leakage,managed by ultrasound-guided puncture.The patient was discharged with drainage tube. The other patient experienced chylous leakage,recovered with conservative treatment. No delayed gastric emptying,hemorrhage or reoperations were observed. The median postoperative hospital stay was 13 days (range: 8 to 20 days).Conclusion:The splenic circulation control technique is simple and safe,and shows certain application prospects in minimally invasive radical resection of pancreatic neck and body cancer.

【Objective】 The two databases，GEO（gene expression omnibus，GEO）and TCGA（the cancer genome alas ，TCGA），were analyzed using bioinformatics methods to screen differentially expressed genes associated and their related regulatory networks in prostate carcinoma. 【Methods】 The prostate carcinoma gene expression chip data （GSE46602 ，GSE55945） downloaded from the GEO database were integrated into the RNA- seq data of the TCGA database. And the differentially expressed genes analysis was performed using GEO2R and the edgeR package of R software to extract common significant differentially expressed genes. The clusterProfiler package of R software was used to enrich the GO（gene ontology ，GO）function enrichment analysis and KEGG（kyoto encyclopedia of genes and genomes， KEGG）pathway analysis. Differentially expressed genes were further constructed into a protein-protein interaction（PPI） network to screen out key genes for regulatory protein expression in prostate carcinoma. Gene analysis results were combined with TCGA clinical follow-up data to analyze the clinical prognostic value of key node genes. 【Results】A total of 278 significant differentially expressed genes were extracted，of which 178 genes were down- regulated and 100 genes were up-regulated. These genes were closely associated with the function and pathway enrichment such as the regulation of proliferation of epithelial cells，metabolism of benzene- containing compounds，the glutathione metabolism，and focal adhesion. The protein-protein interaction network analysis revealed three key protein expression modules and 12 key node genes. Among these key genes，EDN3（endothelin-3），EDNRB（endothelin receptor B）and AMACR（alpha-methylacyl- coa racemase）were closely related to the survival rate of prostate cancer patients. 【Conclusion】Through bioinformatics analysis of gene chip and RNA-seq data in prostate carcinoma，we found that EDN3，EDNRB and AMACR may play an important role in the occurrence and development of prostate carcinoma.

PURPOSE: This study differentiates patient and care delays of breast cancer and explores the related factors as well as the associations with the prognosis in Guangzhou, a southern city of China. METHODS: A cohort of female incident breast cancer patients (n=1,551) was recruited from October 2008 to March 2012 and followed up until January 1, 2016 (n=1,374) in the affiliated hospitals of Sun Yat-sen University. The factors associated with patient and care delays were analyzed with multivariable logistic models. Cox proportional hazards regression models were constructed to estimate the impacts of the delays on the prognosis. RESULTS: There were 40.4% patient delay (≥3 months) and 15.5% care delay (≥1 month). The patient delay, but not the care delay, was significantly related to the clinical stage and consequently worsened the prognosis of breast cancer (hazard ratio, 1.45; 95% confidence interval, 1.09 to 1.91 for progression-free survival). The factors related to an increased patient delay included premenopausal status, history of benign breast disease, and less physical examination. CONCLUSION: Patient delay was the main type of delay in Guangzhou and resulted in higher clinical stage and poor prognosis of breast cancer. Screening for breast cancer among premenopausal women may be an effective way to reduce this delay.

OBJECTIVETo evaluate efficacy and advantages of the Traditional Chinese Medicine (TCM) synthetic rehabilitation therapy in the treatment of wrist dysfunction after distal radius fractures.

METHODSFrom May 2014 to October 2015, 72 patients with distal radius fracture meeting standards were treated using central randomization system for clinical research. All the patients were divided into two groups: 36 patients in test group and 36 in control group. Sixty-nine cases were finished treatment and followed up in the end. The test group fell off 1 case, and the control group fell off 2 cases. The test group was given TCM synthetic rehabilitation (manipulative therapy, joint mobilization, soaking-washing with Chinese medicinal herbs, functional exercise), and the control group was given functional exercise as well as soaking-washing with Chinese medicinal herbs, 3 weeks for both. Five evaluation standards were used in this research, which were grip strength, patient-rated wrist evaluation (PRWE), Gartland and Werley wrist score, self-rating anxiety scale(SAS) and the overall curative effect evaluation. Before treatment(baseline), after 3 weeks of treatment and 3 months after fracture were the three points in time when collected the data.

RESULTSAfter 3 weeks of treatment and 3 months after fracture, the test group had a significantly better results than those of control group in the PRWE, G-W wrist score and the overall curative effect evaluation(<0.05). In terms of grip strength recovery, after 3 weeks of treatment, the intergroup difference between the test group and the control group were statistically significant relative to the baseline regarding grip strength of ipsilateral wrist by group t-test(<0.05). However, the test group and the control group had no statistically significant relative to the baseline at 3 months after fracture in grip strength(<0.05). For the anxiety of patients, compared with the test group and control group at before and after rehabilitation treatment, the anxiety of both test group and control group cases was eased(<0.05). However, The degree of anxiety relief in test group and control group cases had no difference(>0.05).

CONCLUSIONSThe TCM synthetic rehabilitation therapy has better curative effects on the treatment of functional disability of wrist joints after distal radius fractures than the general therapy of soaking-washing with Chinese medicinal herbs and functional exercise.

OBJECTIVETo explore the clinical efficacy and toxicity of CLAT protocol (cladribine, cytarabine and topotecan) for treating patients with refractory acute myeloid leukemia (R-AML).

METHODSA total of 18 patients with R-AML (median age 37 years, range 18 to 58 years; male n = 16, female n = 2) were treated with CLAT protocol, which consisted of cladribine 5 mg/m(2)/d, i.v. on days 1-5, cytarabine 1.5 g/m(2)/d, i.v. on days 1-5, topotecan 1.25 mg/m(2)/d, i.v. on days 1-5 and G-CSF 300 µg/d subcutaneous injection on day 6 until neutrophile granulocyte recovery.

RESULTSOut of 18 patients 2 died of severe infection before the assessment. Among 16 evaluated patients, 10 (55.6%) achieved complete remission (CR), and 2 (11.1%) achieved partial remission (PR), the overall response rate was 66.7%, the rest 4 patients did not respond (NR). The median overall survival time and DFS for the CR patients was 9.5 months (95%CI: 6.7-16.64) and 9.5 months (95%CI: 6.1-16.7) respectively. The 1 year OS and DFS rates were 45% and 46.9%, respectively. All patients developed grade 4 of granulocytopenia and thrombocytopenia, the median duration was 13 (range 2 to 21) days and 12 days (range 2 to 21), respectively, all patients developed infection, 2 patients died of severe infection. The most common non-hematological side effects included nausea, vomiting, diarrhoea, rash, aminotransferase or bilirubin elevation and were grade 1 to 2.

CONCLUSIONThe CLAT protocol seems to have promising for the treatment of refractory AML patients, and patients well tolerated. This CLAT protocol offers an alternative treatment for R-AML patients who received severe intensive treatment, especially with anthracycline-containing chemotherapy.

OBJECTIVETo measure the content of silica in C1 bituminous coal and its combustion products in the high-incidence area of lung cancer in Xuanwei, Yunnan Province, China and to investigate the relationship between high incidence of lung cancer among non-smoking women and silica produced naturally in C1 bituminous coal in Xuan Wei.

METHODSThe C1 bituminous coal widely used in the high-incidence area of lung cancer in Xuanwei was selected as experiment group, while the C2+1, K7, and M30 bituminous coal that was mined and used in the low-incidence area of lung cancer in Xuanwei for more than 10 years were selected as control group. Fourteen paraffin-embedded cancer tissue samples from the non-smoking women with non-small cell lung cancer who were born in Xuanwei and were at least the 3rd generation of the family living there were collected from the department of pathology, the third affiliated hospital of kunming medical university (tumor hospital of yunnan province). Titrimetric potassium silicofluoride method was used to measure the content of silica in raw coal and its bottom ashes in 20 samples from the experimental group and control group. Scanning electron microscopy (SEM) was used to observe the morphology of silica particles in C1 bituminous coal and its bottom ashes, and scanning electron microscopy coupled with energy dispersive X-ray analyzer (SEM-EDX) was used to analyze the microscopic composition. Transmission electron microscope (TEM) was used to observe the morphology of silica particles in the bottom ashes and coal soot of C1 bituminous coal as well as the lung cancer tissue from the non-smoking women in Xuanwei, and transmission electron microscope coupled with energy dispersive X-ray analyzer (TEM-EDX) was used to analyze the microscopic composition. The silica particles were separated from the coal soot and bottom ashes and characterized by physical method.

RESULTSThe silica content in C1 bituminous coal and its bottom ashes was significantly higher than that in C2+1, K7, and M30 bituminous coal (P < 0.05). The bottom ashes of C1 bituminous coal contained a large quantity of silica particles, mostly with microscale sizes. Silica particles were found in the soot of C1 bituminous coal and the lung cancer tissue from non-smoking women in Xuanwei. The silica particles in the bottom ashes were mostly 120 ∼ 500 nm in diameter, had various shapes, and contained such elements as iron, aluminium, calcium, and potassium; the silica particles in the coal soot were mostly nanoscale, ranging from 37 nm to 80 nm in diameter, had various shapes, with some in fibrous form, had non smooth surfaces, and contained such elements as iron, potassium, calcium, aluminium, and sulfur.

CONCLUSIONIn Xuanwei, the incidence of lung cancer among non-smoking women is high in the area where silica-rich C1 bituminous coal is produced. There are silica particles enriched in both the combustion products (coal soot and bottom ashes) of C1 bituminous coal and the cancer tissue from the non-smoking women with non-small cell lung cancer, with similar morphology and microscopic composition. We hypothesize that the silica particles from combusted C1 bituminous coal in Xuanwei are mixed with indoor air and inhaled along with other suspended particles.
