Objective:To evaluate the efficacy and safety of combined cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) with lobaplatin and docetaxel for treatment of synchronous peritoneal carcinomatosis (PC) from gastric cancer. Methods:Fifty patients with synchronous PC from gastric cancer were treated by 52 CRS+HIPEC procedures with 100 mg of lobaplatin and 120 mg of docetaxel in 12000 mL of normal saline at (43 ± 0.5)℃for 60 min. The primary and secondary endpoints were overall survival (OS) and perioperative safety profiles, respectively. Results:At a median follow-up of 22.5 months, the median OS rate was 14.3 (95%CI:7.6-21.0) months, and the 1-, 2-, and 3-year survival rates were 58%, 40%, and 32%, respectively. No perioperative deaths or serious adverse events occurred in 12 cases (23.1%). Multivariate analysis indicated that completeness of cytoreduction, nor-mality of perioperative tumor markers, and adjuvant chemotherapy of more than six cycles were independent predictors for improved survival. Conclusions:CRS+HIPEC with lobaplatin and docetaxel could improve the OS and ensure perioperative safety of patients with synchronous PC from gastric cancer.

Objective:To investigate whether the omental-adipose stromal cells (O-ASCs) exposing to gastric cancer-conditioned medi-um (CM) could be inducted to differentiate into carcinoma-associated fibroblasts (CAFs) and the effect of ERK signaling pathway in the process. Methods: We identified O-ASCs by examining their ability to differentiate osteogenic and adipogenic lineages and through flow cytometry. O-ASCs were co-cultured with MGC803 and SGC7901CM. The expression of CAFs markers (α-SMA, FSP-1, and vimentin) and paracrine factors (VEGFA, TGF-β1, FAP, and SDF-1) were evaluated by RT-PCR and Western blot. In vitro cultures of O-ASCs were divided into three groups:the control, SGC7901-CM, and SGC7901-CM+U0126 groups. Cells were collected after 12 h. West-ern blot was performed to evaluate the expression ofα-SMA, FSP-1, ERK, and p-ERK1/2. Results:The primary cells were O-ASCs. The expression levels of CAFs markers (α-SMA, FSP-1, and vimentin) and O-ASC paracrine factors (VEGFA, TGF-β1, FAP, and SDF-1) clearly in-creased (P<0.05). In comparison with the control, the expression of ERK in SGC7901-CM group did not change (P>0.05), while the ex-pression of p-ERK1/2,α-SMA, and FSP-1 significantly improved (P<0.05). Comparison of SGC 7901-CM+U0126 and SGC 7901-CM groups showed that the expression levels of ERK had no statistical difference (P>0.05), while the expression levels of p-ERK1/2,α-SMA, and FSP-1 decreased (P<0.05). Conclusion:O-ASCs participate in the peritoneal metastasis of gastric cancer through differentiation by CAF and paracrine factors. The ERK signaling pathway is important in the differentiation of O-ASCs towards CAFs.

Objective:For cancer patients who underwent extensive surgery, drastic release of myoglobin (Mb) after surgery can cause hypermyoglobinemia and related problems. This retrospective cohort study aims to summarize our experience and outcomes of 60 pa-tients with hypermyoglobinemia after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), to investi-gate the changes in postoperative Mb levels, and to explore the clinical value of Mb. Methods:This retrospective study covered 60 pa-tients with peritoneal carcinomatosis who were treated with CRS and HIPEC. All patients developed hypermyoglobinemia after opera-tion. Immediately after CRS and HIPEC, the patients were placed in a comprehensive treatment regimen consisting of hemodynamic stabilization therapies, nutritional support, anti-sepsis therapies, and psycho-physical therapies. For the treatment of hypermyoglo-binemia, intravenous injection of sodium bicarbonate solution according to the Mb level was given to the patients. Moreover, the pre-and post-operative concentrations of Mb, blood urea nitrogen (BUN), and creatinine (Cr) were evaluated. Results:Serum Mb levels af-ter CRS and HIPEC were significantly elevated and peaked on the surgery day. Prompt treatment with intravenous infusion of sodium bicarbonate solution could help decrease the serum Mb levels and alleviate potential damage. Serum Mb levels returned to normal in approximately 3-4 days. The serum BUN levels increased after operation and peaked on the fourth postoperative day. On the other hand, serum Cr levels increased 2 days after operation and began to decrease on the third postoperative day. One patient developed renal failure and sepsis and died on postoperative day 26. The other patients recovered from the surgery without major adverse events. Conclusion:Hypermyoglobinemia is a common lab abnormality after CRS and HIPEC, and serum Mb levels could be an early and sensitive indicator for dramatic disturbances in the internal milieu after surgery. Adequate treatment with sodium bicarbonate could accelerate the reduction in serum Mb levels and reduce the risk for major organ damages.

ObjectiveTo establish a theoretical system of pharmacokinetic and spectrokinetic dose-time characterization of traditional Chinese medicine(TCM). By analyzing the pharmacokinetic and spectrokinetic behaviors of Lonicerae Flos, Houttuyniae Herba injection, Lonicerae Japonicae Flosand Buyang Huanwutang, this paper compared the similarities and differences of the three methods for characterizing the dose-time relationship, namely half-life, statistical moment and statistics, in order to find the most suitable method for characterizing the relationship. MethodTen mice were randomly selected from 100 Kunming mice as the blank group, and the remaining mice were coated with xylene in the auricle to establish the acute inflammation model of ear swelling. After successful modeling, the mice were gavaged with aqueous extract of Lonicerae Flos(30 g∙kg-1), and the blank group was gavaged with an equal volume of normal saline. The plasma of mice was collected at different time points to determine the content changes of components. At the same time, the pharmacokinetic results of Houttuyniae Herba injection, Lonicerae Japonicae Flos and Buyang Huanwutang were included, and the pharmacokinetic and spectrokinetic parameters were calculated. Then the difference in the time of calculating 95% total component content of metabolism by half-life method, statistical moment method and statistical method was compared. ResultOn the basis of the half-life method, the mathematical expressions of statistical moment method and statistical method suitable for the characterization of dose-time relationship of multi-component system of TCM were established. The results showed that the pharmacokinetic parameters of the individual components in Lonicerae Flos varied, with cryptochlorogenic acid and rutin showing a two-compartment model and the other components showing a one-compartment model. After calculation of spectrokinetic similarity, the metabolic patterns among the components contained in Houttuyniae Herba injection, Lonicerae Japonicae Flos, Lonicerae Flos and Buyang Huanwutang were different and varied greatly in vivo. The time to metabolize 95% of the total components of the four research subjects in vivo was calculated by the half-life method, statistical moment method and statistical method, and it was found that the difference between statistical moment method and half-life method was large, and the difference between statistical moment method and statistical method was small. ConclusionStatistical method not only reflects the characteristics of statistical moment method, characterizes the dispersion degree of each component, but also can be associated with fingerprint to form spectrokinetics, characterizing the dose-time relationship of 95% of drug components, which is a more desirable method to characterize the dose-time relationship of the component groups in TCM.
