Objective:To explore the clinical efficacy and influence on quality of life of Compound Kunshen Injection combined with SOX regimen (Tigio + Oxaliplatin) in the treatment of elderly patients with advanced gastric cancer.Methods:A total of 76 elderly patients with advanced gastric cancer admitted to Caidian District People's Hospital of Wuhan from May 2017 to December 2021 were retrospectively analyzed. Patients were divided into study group ( n=38) and control group ( n=38) according to different treatment methods. The study group was treated with Compound Kunshen Injection combined with SOX regimen, and the control group was treated with SOX regimen. All patients received at least 2 cycles of chemotherapy. The disease control rate (DCR) , the changes of serum carcinoembryonic antigen (CEA) and carbohydrate antigen 199 (CA199) before and after treatment of the two groups were compared. The occurrence of adverse reactions to chemotherapy and the improvement of quality of life related indicators before and after treatment were observed in the two groups. Results:The DCR of the study group was 84.2% (32/38) and that of the control group was 63.2% (24/38) , with a statistically significant difference ( χ2=4.34, P=0.037) . After treatment, CEA levels in both study group and control group were decreased compared with those before treatment [7.92 (5.00, 50.23) ng/ml vs. 40.08 (6.37, 68.18) ng/ml, Z=3.53, P<0.001; 40.24 (20.12, 53.69) ng/ml vs. 41.32 (11.50, 63.90) ng/ml, Z=2.06, P=0.044], and CEA level in the study group was decreased more significantly than that in the control group ( Z=1.99, P=0.048) . After treatment, CA199 levels in both study group and control group were decreased compared with those before treatment [20.23 (17.34, 71.31) U/ml vs. 70.14 (12.75, 96.95) U/ml, Z=2.70, P=0.007; 54.25 (30.54, 76.75) U/ml vs. 62.28 (23.00, 84.80) U/ml, Z=2.37, P=0.018], with no statistically significant difference in the reduction level of CA199 between the two groups ( Z=0.73, P=0.463) . Most of the adverse reactions in the two groups during chemotherapy were grade 1-2, which disappeared after symptomatic treatment. Compared with the control group, the study group had lower incidence of gastrointestinal reaction [26.3% (10/38) vs. 52.6% (20/38) , χ2=5.50, P=0.019], myelosuppression [18.4% (7/38) vs. 44.7% (17/38) , χ2=6.09, P=0.014] and peripheral neurotoxicity [21.1% (8/38) vs. 44.7% (17/38) , χ2=4.83, P=0.028]. The improvements of QOL score [78.9% (30/38) vs. 55.3% (21/38) , χ2=4.83, P=0.028], Karnofsky performance status score [71.1% (27/38) vs. 47.4% (18/38) , χ2=4.41, P=0.036], hemoglobin [73.7% (28/38) vs. 50.0% (19/38) , χ2=4.52, P=0.034] and pain control [65.8% (25/38) vs. 24.1% (16/38) , χ2=4.29, P=0.038] of the study group were better than those of the control group, with statistically significant differences. Conclusion:Compound Kunshen Injection combined with SOX regimen in the treatment of elderly patients with advanced gastric cancer can not only improve the DCR of patients, but also reduce the serum levels of tumor markers CEA and CA199, among which the CEA decline is more obvious, reduce the incidence of adverse reactions of chemotherapy and improve the quality of life of patients.

In this study, voltage was used as a disturbance factor to investigate the relationship between microbial community and methane (CH₄) production flux in a microbial electrolytic cell coupled anaerobic digestion (MEC-AD). Metabolic flux analysis (MFA) was used to explore the relationship between the CH₄ metabolic flux produced and the microbes. The results showed that both methane production flux and hydrogen production flux changed significantly upon voltage disturbance, while the voltage disturbance had little effect on acetic acid production flux. The maximum CH₄ production flux under 0.6 V disturbance was 0.522±0.051, which increased by 77% and 32%, respectively, compared with that of the control group under 1.0 V (0.295±0.013) and under 1.4 V (0.395±0.029). In addition, an average of 15.7%±2.9% of H₂ (flux) was used to reduce CO₂ to produce CH₄ and acetic acid, and an average of 27.7%±6.9% of acetic acid (flux) was converted to CH₄. Moreover, the abundance of Lachnospiraceae significantly affected the flux of acetic acid. The flux of CH₄ production is positively correlated with the abundances of Petrimonas, Syntrophomonas, Blvii28, and Acinetobacter, and negatively correlated with the abundances of Tuzzerella and Sphaerochaeta. The species that affected the flux of H₂ and CH₄ were similar, mostly belonging to Bacteroides, Clostridium, Pseudomonas and Firmicutes. Furthermore, the interspecies interaction is also an important factor affecting the MEC-AD methanogenesis flux.

Objective To explore the change and clinical significance of the serum carcinoembryonic antigen (CEA)and carbohydrate antigen 724(CA724)in patients with rectal cancer before and after neoadjuvant ra-diotherapy and chemotherapy.Methods The serum levels of CEA and CA724 of 30 patients with rectal carci-noma were detected by electrochemiluminescence method and were compared with those in 30 healthy people. Results The serum levels of CEA and CA724 in rectal carcinoma patients before neoadjuvant radiotherapy and chemotherapy were significantly higher than those in the healthy people,the difference was statistically significant(P<0.05).The serum levels in complete remission and partial remission patients after eight-week neoadjuvant radiotherapy and chemotherapy were significantly lower than those before treatment,the differ-ence was statistically significant(P<0.05),and the reduction levels were obviously higher than those in the stable group,the difference was statistically significant(P< 0.05).The CEA and CA724 levels in the stable treatment patients were also lower than those of before neoadjuvant radiotherapy and chemotherapy,the difference was statistically significant(P<0.05).The serum levels in the progression group were higher than those of before treatment(P<0.05).The serum levels of CEA and CA724 before neoadjuvant radiotherapy and chemotherapy existed a positive correlation(r=0.862,P=0.000).Conclusion The serum levels of CEA and CA724 in rectal cancer are highly expressed,suggesting that both of them are closely related to the occur-rence and development of rectal carcinoma,the measurement of the serum level changes of CEA and CA724 in patients with rectal cancer before and after treatment contributes to estimate the efficacy of neoadjuvant radio-therapy and chemotherapy and tumor progression.

OBJECTIVE: To investigate the effect of vitamin D3 on polarization of monocyte macrophages induced by serum from patients with ankylosing spondylitis (AS). METHODS: Twenty AS naïve patients and 20 healthy controls from Wenzhou People's Hospital during January 2016 and December 2017 were enrolled. The macrophages were differentiated from THP1 cells induced by phorbol 12-myristate 13-acetate (PMA), and then co-cultured with the serum from healthy subjects (control group) or AS patients. Vitamin D3 was added in the medium mixed with serum from AS patients. Flow cytometry was used to analyze the ratio of CD68 and CD206 positive cells, and RT-PCR was performed to detect the mRNA expression of inducible nitric oxide synthase(iNOS) and arginase-1(Arg-1). RESULTS: THP1 cells could be polarized into mononuclear-macrophages with the induction of PMA. The proportion of CD206 positive cells in AS-serum group was lower than that in the control group (=9.434, <0.05), while the proportion of CD68 positive cells was higher than that in the control group (=43.920, <0.05). The proportion of CD206 positive cells in vitamin D3 group was higher than that in AS-serum group (=8.895, <0.05), while the proportion of CD68 positive cells was lower than that in AS-serum group (=9.089, <0.05). mRNA expression of Arg-1 in AS-serum group was lower than that in the control group (=8.899, <0.05), while mRNA expression of iNOS was higher than that in the control group (=3.656, <0.05). mRNA expression of Arg-1 in vitamin D3 group was higher than that in AS-serum group (=6.219, <0.05), while mRNA expression of iNOS was lower than that in AS-serum group (=5.876, <0.05). CONCLUSIONS Vitamin D3 can regulate the polarization of mononuclear macrophages for immunoregulation in patients with AS.

Objective To investigate the expression of circulating tumor cells (CTC) in peripheral blood of patients with different stages of colorectal cancer (CRC), and to evaluate its significance in early diagnosis of colorectal cancer metastasis. Methods Sixty patients with CRC (42 inⅡ-Ⅲstage and 18 in IV stage ) and 30 patients with benign rectal disease were recruited from January 2014 to December 2015. The CTC in peripheral blood was purified with Immunomagnetic Separation Technologie, and detected by immunofluorescence in situ hybridization (imFISH). The serum levels of CEA were detected by electrochemiluminescence method meanwhile. The correlation between CTC and CEA was analyzed. Results CTC positive rates in CRC patients were significantly higher than those in benign rectal disease controls. CTC positive rates inⅣstage were significantly higher than those inⅡ-Ⅲ stage. The expression of CTC was significantly correlated with CEA (r = 0.6652, P < 0.01). Conclusions The expression of CTC in CRC patients is significantly higher than that in benign rectal disease control group. It is closely related to clinical stages. Detection of peripheral blood CTC has important clinical significance in the early diagnosis of CRC metastasis.

Objective To investigate the distribution and changing resistance proifle ofSalmonella isolates in hospitals across China during the period from January 2005 to December 2014.Methods Seventeen general hospitals and two children’s hospitals were involved in this program. Antimicrobial susceptibility testing was carried out by means of a unified protocol using Kirby-Bauer method or MIC determination. The results were analyzed according to CLSI 2014 breakpoints.Results The proportion ofSalmonella isolates increased with time from 0.2% in 2005 to 0.7% in 2014. A total of 3 478Salmonella strains were collected from 19 hospitals. The proportion ofSalmonella typhimurium andSalmonella enteritidis was 27.4% and 24.4%, respectively. During the 10-year period, theSalmonella strains showed highest resistance rate to ampicillin (33.3%-64.8%), but low resistance to cefoperazone-sulbactam (0-5.3%) and ciprofloxacin (2.4%-14.3%).S. typhimurium showed higher resistance rate thanS. typhi,S. paratyphi andS. enteritidis. About 76.8% and 50.5% ofS. typhimurium were resistant to ampicillin and trimethoprim-sulfamethoxazole. The average prevalence of multi-drug resistantSalmonellawas 3.9% in the ten-year period, the highest (7.5%) was in 2005, the lowest (1.5%) in 2013.Conclusions During the period from 2004 to 2015, majority of theSalmonella isolates in hospitals across China wasS. typhimurium andS. enteritidis. Ampicillin and trimethoprim-sulfamethoxazole are no longer appropriate for empirical treatment ofS. typhimurium infection due to high resistance rate.Salmonella isolates are relatively more susceptible to third-generation cephalosporins and quinolones. Ongoing monitoring is necessary to identify multi-drug resistant strains ofSalmonella.
