Objective To evaluate the stimulative role of the enhanced recovery program after surgery (ERAS) protocol in patients undergoing radical resection for gastric cancer.Methods A total of 102 consecutive patients undergoing elective gastric resection were included in either the ERAS (n =35,received ERAS perioperative treatment from June 2013 to June 2014) or the control group (n =67,received conventional perioperative treatment from June 2011 to June 2013).Outcomes related to nutrition index,stress index,and recovery index were measured.Results The nutritional index of patients (total lymphocyte count,serum albumin and prealbumin) in the ERAS group was improved on postoperative day (POD) 1 compared with that in the control group [(1.25±0.65) × 109/L vs (1.09±0.71) × 109/L,(36.4±5.2) g/L vs (31.3±4.1) g/L,(0.19±0.08) g/L vs (0.17±0.05) g/L,P ＜ 0.05,respectively].The level of negative nitrogen balance on POD 1 in the ERAS group was slightly lower than that in the control group (P ＞ 0.05),and the level of negative nitrogen balance on POD 7 in the ERAS group was higher than that in the control group (-0.93±2.17 vs -3.87±4.45,P ＜ 0.05).The postoperative cortisol level in the control group was elevated on both POD 1 (P ＜ 0.05) and POD 7 (P ＜ 0.05) compared to the preoperative level [(5.06±1.87) mg/L vs (3.60±1.5) mg/L],(5.15±1.33) mg/L vs (3.60±1.51) mg/L,P ＜ 0.05,respectively].However,the cortisol level was not increased until POD 7 in the ERAS group [(5.08±1.18) mg/L vs (3.20±1.43) mg/L,P ＜ 0.05].The level of IL-6 was elevated in postoperative period compared to preoperative period both in two groups (P ＜ 0.05).And the level of IFN-γin the ERAS group on POD 1 was reduced compared to the preoperative level (P ＜ 0.05).Whether in preoperative or postoperative,the level of IL-1β and TNF-α showed no statistical significance change.In addition,the postoperative recovery conditions (day of oral all-liquid recovery,first day of defecation,hospital stay,maximum pain on visual analogue scale) in the ERAS group were better than those in the control group (P ＜ 0.05).The incidence rates of complications between the two groups were 13.4 ％ (9/67) and 17.1％ (6/35) respectively (P ＞ 0.05).Conclusion ERAS protocol can alleviate surgical stress response and accelerate postoperative recovery without compromising patients' safety.

Objective To study the factors related to the infection induced by internal jugular catheterization and femoral vein catheterization.Methods Bacterial culture was conducted for samples collected from the outer section of catheters,the skin around the catheters and the puncture sites during different stages of the catheterization as well as the cathetor blood before removal and the catheter tips after removal in 75 cages after deep vein catheterization from March to August,2008.Statistic analysis was made on positive results.Results The positive rate of the bacterial culture in femoral vein group was obviously higher than the internal jugular group.Rank correlation analysis indicated:the positive rate of the bacterial culture for the puncture site was highly correlated with that for the outer section of the catheters and the skin around the catheters;and the catheter blood(at the tip)was in low positive correlation with that ofthe puncture site and the skin around catheters.And the positive rate apparently rose on the 3～7th days after the catheterization.Conclusions The catheter-related infection after CVC was closely correlated with the outer section of the catheters,the bacterial pollution to the akin around the catheters and different stages of the catheterization in addition to catheterizing location.It is suggested that nurses should choose proper catheterizing position according to different purposes while paying attention to the nursing work for the puncturing part and during the stage with hish risk of infection so as to reduce the occurrence of catheter-related infection.

Advanced gastric cancer without distant metastasis remains a potentially curable disease, but the prognosis is poor in this condition because of the high unresectability rate at presentation and the high recurrence rate after radical surgery. Administration of neoadjuvant chemotherapy has several potential benefits for advanced gastric cancer. This treatment can decrease tumor stage and improve R0 resection rate. Neoadjuvant chemotherapy has higher patient tolerability and a higher rate of chemotherapy completion than adjuvant chemotherapy. In vivo drug sensitivity tests can also be conducted to avoid unnecessary surgeries. Although high-intensi-ty chemotherapy results in a high overall response rate, a few advanced gastric patients can achieve a pathologically complete re-sponse. However, no standardized treatment has been achieved. This article introduces five cases of advanced gastric cancer treated with neoadjuvant chemotherapy in the Affiliated Tumor Hospital of Guangxi Medical University. The five cases achieved a pathological complete response. This article also aims to explore the clinicopathological characteristics of these patients, proper cooperative treat-ment practices, and prognostic factors for the benefit of future patients.

Objeetive To investigate the effectiveness and safety of agomelatine for the treatment of elderly patients with post-stroke depression.Methods A total 80 elderly patients with post-stroke depression were randomly divided into either an agomelatine group or a sertraline group.The Hamilton Depression Scale (HAMD),National Institutes of Health Stroke Scale (NIHSS) and Barthel Index were used to evaluate the patients before and after 1,2,4,and 6 weeks,respectively.Results HAMD,NIHSS,and Barthel index scores were improved significantly after treatment in the agomelatine group (n =38) and the sertraline group (n =42).There were significant improvement in the scores of HAMD,NIHSS and Barthel Index with time in both groups (all P ＜0.001).There were no significant difference in the scores of HAMD and NIHSS at different time points after treatment between the agomelatine group and the sertraline group,and the Barthel Index scores began to have significance difference from the fourth week after treatment (all P ＜ 0.05).Conclusions The efficacy of agomelatine for the treatment of PSD is almost the same as sertraline,and the effect of improving activities of daily living is better than sertraline.The safety of both agomelatine and sertraline is good.

The etiology and pathogenesis of depression is complex, the regulation of serotonin signaling pathway is one of the most important mechanisms for commercially available antidepressants. In addition to serotonin transporter, recent studies have shown many other serotonin receptor subtypes also play an important role in the treatment of depression, which has become one of the hot topics of antidepressants. Therefore, the progress of serotonin receptors and new structure with the activity of regulating serotonin receptors as well as part of the structure-activity relationships are reviewed in this paper in order to provide reference for the further research and development of antidepressants.

Objective To compare the clinical efficacy and safety of agomelatine and paroxetine for the senile depression. Methods A total of 98 cases of elderly patients diagnozed with depression were randomly divided into two groups, one group were treated with agomelatine,the other group were treated with paroxetine,treated for 6 weeks, using Hamilton depression scale(HAMD), adverse reaction scale(TESS) to evaluate the efficacy and adverse reactions. Results After 6 weeks of treatment, the HAMD scores showed that there were no significant differences in clinical efficacy of two groups, and the TESS showed the agomelatine had less adverse reaction than the paroxetine. Conclusion Agomelatine is a safe and effective antidepressant , suitable for elderly patients.

In recent years, the genome editing technologies based on the clustered regularly interspaced short palindromic repeats/CRISPR-associated protein (CRISPR/Cas) have developed rapidly. The system can use homologous directed recombination (HDR) to achieve precise editing that it medicated, but the efficiency is extremely low, which limits its application in agriculture and biomedical fields. As an emerging genome editing technology, the CRISPR/Cas-mediated DNA base editing technologies can achieve targeted mutations of bases without generating double-strand breaks, and has higher editing efficiency and specificity compared with CRISPR/Cas-mediated HDR editing. At present, cytidine base editors (CBEs) that can mutate C to T, adenine base editors (ABEs) that can mutate A to G, and prime editors (PEs) that enable arbitrary base conversion and precise insertion and deletion of small fragments, have been developed. In addition, glycosylase base editors (GBEs) capable of transitioning from C to G and double base editors capable of editing both A and C simultaneously, have been developed. This review summarizes the development, advances, advantages and limitations of several DNA base editors. The successful applications of DNA base editing technology in biomedicine and agriculture, together with the prospects for further optimization and selection of DNA base editors, are discussed.
