Peritoneal metastasis in gastric cancer is associated with rapid disease progression. Hyperthermic intraoperative peritoneal chemotherapy (HIPEC) done immediately after cytoreductive surgery (CRS) has become an important treatment for peritoneal metastasis in gastric cancer patients. However, different treatment options for HIPEC exist with potential influence on survival rates and prognosis in patients, exist. These treatment options include open or closed abdomen technique, perfusion solution, number of catheters, temperature, duration, and drug regimens. This paper aims to provide more evidence on standardization of HIPEC treatment options and technologies by systematically reviewing different drug regimens and technical approaches. The study included 2 randomized controlled trials, 3 phase I/II clinical trials, 2 prospective cohort studies, and 34 retrospective cohort studies, involving 1511 patients. The most common HIPEC option is to dissolve 50-75 mg/m 2 of Cisplatin and 30-40 mg/m 2 of Mitomycin C in 3-4 L saline solution at 42-43℃. After gastrointestinal anastomosis, 2-3 catheters are used in the HIPEC system with a perfusion flow rate of 500 ml/min. The duration is 60-90 minutes. Anastomotic leakage was low in studies where HIPEC was performed after gastrointestinal anastomosis. The utilization of open HIPEC and a two-drug regimen resulted in improved overall survival rates. The future development of HIPEC aims to enhance tumor-specific therapy by optimizing various aspects, such as identifying the safest and most effective chemotherapy regimens, refining patient selection criteria, and improving perioperative care.

OBJECTIVE Alzheimer's disease(AD)and vascular dementia(VD)are the primary causes of dementia in elderly individuals,and therapeutic options for both conditions are limited.Overactivation of N-methyl-D-aspartate(NMDA)receptors,decreased cerebral blood flow,and subsequent pathological events,play signifi-cant roles in the progression of AD and VD.METHODS In this study,we investigated the therapeutic effects and underlying mechanisms of MN-08,a novel memantine nitrate,in mouse models of AD and rats with VD.RESULTS MN-08 was found to inhibit Aβ accumulation,prevent neuronal and dendritic spine loss,and attenuate cognitive deficits in 2-month-old APP/PS1 transgenic mice(following a 6-month preventative course)and in 8-month-old triple-transgenic(3×Tg-AD)mice(following a 4-month therapeutic course),as well as in rat models of VD with preventive and therapeutic treatments.In vitro,MN-08 was shown to bind to and antagonize NMDA receptors,inhibit calcium influx,and reverse dysregula-tions of the ERK and PI3K/Akt/GSK3β pathway,subse-quently preventing glutamate-induced neuronal loss.Additionally,MN-08 exhibited favorable pharmacokinet-ics,blood-brain barrier penetration,and safety profiles in rats and beagle dogs.CONCLUSION These findings suggest that the novel memantine nitrate MN-08 may be a useful therapeutic agent for AD and VD.

Thanks to the process reengineering of appointment registration, outpatient doctor′s advice, payment and mobile Internet application system, multiple payment queues in outpatient service have been replaced by automatic book keeping of the information system. This reform, based on short message reminders and the credit mechanism, has effectively reduced queuing time in convenience of the outpatients.

OBJECTIVE: To identify potential mutations of the CLS gene in a Chinese pedigree affected with Coffin-Lowry syndrome. METHODS: Whole exome sequencing was applied to detect potential mutation in the proband, and the result was verified by Sanger sequencing. RESULTS: The proband was found to carry a c.966_967delAA (p.Arg323Thr fs*11) deletional mutation in the RPS6KA3 gene. The same mutation was also found in his mother. CONCLUSION The c.966_967delAA (p.Arg323Thr fs*11) deletional mutation of the RPS6KA3 gene probably underlies the disorder in this pedigree.

These efforts can meet the long-term drug demands of such patients during their stable conditions, providing technology support for sustainable management and service for chronic disease patients.

BACKGROUND:Sodium butyrate, a histone deacetylase inhibitor, can inhibit cell proliferation, and induce apoptosis and differentiation of various cancer cells. However, the role of sodium butyrate combined with tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) on lung cancer stem cells remains unclear. OBJECTIVE:To explore the effect of sodium butyrate combined with TRAIL on biological behaviors of lung cancer stem cells. METHODS:Magnetic bead separation was used to separate lung cancer stem cells (CD133+) from human lung adenocarcinoma A549 cells. After the lung cancer stem cells were treated with simple DMEM/F12, DMEM/F12 containing sodium butyrate (5 mmol/L), TRAIL (50 μg/L) or sodium butyrate combined with TRAIL, the cell proliferation within 96 hours of culture was determined by MTT assay; the apoptosis within 24 hours of culture was measured by flow cytometry; the cell migration within 48 hours of culture was detected by cell scratch test; the expression levels of pluripotent transcription factors (Oct4, Sox2 and Nanog) within 48 hours of culture were detected using western blot analysis. RESULTS AND CONCLUSION:The CD133+ lung cancer stem cells were successfully enriched from human lung adenocarcinoma A549 cells. MTT assay showed that sodium butyrate and TRAIL significantly inhibited the proliferation of lung cancer stem cells (P< 0.05), and the combination effect was even stronger (P < 0.05). Results from flow cytometry analysis and scratch test showed that sodium butyrate or TRAIL induced apoptosis and inhibited cell migration of lung cancer stem cells (P < 0.05), and the combination of sodium butyrate and TRAIL showed a stronger effect (P < 0.05). In addition, the expression levels of Oct4, Sox2 and Nanog were significantly down-regulated by sodium butyrate (P < 0.05), TRAIL or sodium butyrate combined with TRAIL, and the combination effect was stronger (P < 0.05). In conclusion, sodium butyrate and TRAIL have synergistic effects on lung cancer stem cells, indicating a new way for treatment of lung cancer.

Objective To explore the changes of deceleration capacity of rate (DC) and analyze its correlation with heart rate variability (HRV) and other factors in patients with coronary heart disease. Methods One hundred and twenty-nine patients with coronary heart disease (coronary heart disease group) and 109 healthy people (control group) were enrolled in this study. DC and HRV parameters were measured by using digitized 24 h Holter. The correlation between DC and HRV parameters, other factors were analyzed. Results The levels of DC, SDNN, SDANN, SDNNi, PNN50, TP, LF, HF, AC in coronary heart disease group were significantly lower than those in control group:(5.64±1.67) ms vs. (6.71±1.47) ms, (106.60±20.53) ms vs. (138.82±31.22) ms, (96.94±20.06) ms vs. (127.47±31.87) ms,(28.53±14.75) ms vs. (52.24±14.65) ms, 87.72%vs. 103.86%,(1 967.10±966.16) ms2/Hz vs. (2 846.70±1 443.41) ms2/Hz,(326.43±195.35) ms2/Hz vs.(457.64±254.30) ms2/Hz, 85.88 vs. 106.39, (-6.18±2.15) ms vs. (-7.00±2.51) ms, P<0.05 or<0.01. DC was correlated with SDNNi, PNN50,TP,LF, HF, AC both in total population or in coronary heart disease group and control group by using multiple linear correlation analysis ( r=0.586, 0.356, 0.531, 0.563, 0.435,-0.433, P<0.01). After removing confounders, DC was correlated with age, SDNNi, rMSSD, PNN50 and AC (P<0.01). Conclusions DC decreases in patients with coronary heart disease and is strong correlativity with HRV parameters. DC could be used for quantitative detection of autonomic nervous function.
