High dose chemoradiotherapy increases chance of organ preservation with satisfactory functional outcome for rectal cancer.

BACKGROUND: High dose chemoradiotherapy offers a curative chance for patients with rectal cancer that are unfit or unwilling to undergo surgical resection, yet its long-term survival and functional outcomes have been rarely investigated. METHODS: Patients with non-metastatic rectal adenocarcinoma who received pelvic radiation for curative intent from April 2006 to July 2017 were retrospectively investigated. Survival rates were analyzed using the Kaplan-Meier method. Quality of life and functional outcomes were evaluated using the EORTC quality of life questionnaire. RESULTS: A total of 57 patients were included, with a median age of 59.0 (range, 29-84) years. The numbers of patients who were diagnosed as stage I, II and III were 5 (8.8%), 16 (28.1%) and 36 (63.2%), respectively. 53 (93.0%) patients had tumor located within 5 cm from the anal verge. All patients received fluorouracil-based concurrent chemoradiotherapy with a median radiation dose of 80 (range, 60-86) Gy. All kinds of grade 3-4 adverse events occurred in 18 (31.6%) patients. 42 (73.7%) patients achieved a clinical complete response after chemoradiotherapy. After a median follow-up of 43.5 (range 14.9-163.2) months, 12 (21.1%) patients had local progression and 11 (19.3%) developed distant metastasis. The 3-year local recurrence-free survival and distant metastasis-free survival were 77.3% (95% CI, 65.7-88.8%) and 79.2% (95% CI, 68.2-90.2%), while the 3-year progression-free survival, cancer-specific survival, overall survival were 61.9% (95% CI, 48.8-75.0%), 93.1% (95% CI, 85.8-100.0%) and 91.4% (95% CI, 83.6-99.2%), respectively. For patients who had tumor located within 3 cm from the anal verge, the sphincter preservation rate was 85.3% at last follow-up. Long-term adverse events mainly were anal blood loss. 21 patients completed the quality-of-life questionnaire and had a score of the global health status of 78.57 ± 17.59. Of them, 95.2% reported no urinary incontinence and 85.7% reported no fecal incontinence. CONCLUSIONS: High dose chemoradiation demonstrated promising survival outcomes with acceptable short-term and long-term side effects, and satisfying long-term functional outcomes and quality of life. It could be considered as a non-invasive alternative for rectal cancer patients who refuse surgery.

Neoadjuvant chemoradiotherapy for patients with unresectable radically locally advanced colon cancer: a potential improvement to overall survival and decrease to multivisceral resection.

BACKGROUND: The management of unresectable locally advanced colon cancer (LACC) remains controversial, as resection is not feasible. The goal of this study was to evaluate the treatment outcomes and toxicity of neoadjuvant chemoradiotherapy (NACRT) followed with surgery and adjuvant chemotherapy in patients with unresectable radically LACC. METHODS: We included patients who were diagnosed at our institution, 2010-2018. The neoadjuvant regimen consisted of radiotherapy and capecitabine/ 5-fluorouracil-based chemotherapy. RESULTS: One hundred patients were identified. The median follow-up time was 32 months. The R0 resection rate, adjusted nonmultivisceral resection rate and bladder preservation rate were 83.0, 43.0 and 83.3%, respectively. The pCR and clinical-downstaging rates were 18, and 81.0%%, respectively. The 3-year PFS and OS rates for all patients were 68.6 and 82.1%, respectively. Seventeen patients developed grade 3-4 myelosuppression, which was the most common adverse event observed after NACRT. Tumor perforation occurred in 3 patients during NACRT. The incidence of grade 3-4 surgery-related complications was 7.0%. Postoperative anastomotic leakage was observed in 3 patients. CONCLUSIONS: NACRT followed by surgery was feasible and safe for selected patients with LACC, and can be used as a conversion treatment to achieve satisfactory downstaging, long-term survival and quality of life, with acceptable toxicities.

Enzyme-treated soy protein supplementation in low protein diet enhanced immune function of immune organs in on-growing grass carp.

A 56 days feeding trial was conducted to investigate the effects of enzyme-treated soy protein (ETSP) supplementation in low protein diets on immune function of immune organs (head kidney, spleen and skin) in on-growing grass carp. A total of 540 on-growing grass carp (initial average weight: 325.72 ± 0.60 g) were fed six diets, which included a normal protein diet (28% crude protein) and five low protein diets (26% crude protein) supplemented with graded levels of ETSP (0.0, 0.8, 1.2, 1.6 and 2.0%). At the end of feeding period, a challenge test was performed by infection with Aeromonas hydrophila for two weeks. The results indicated that (1) reducing dietary protein content from 28 to 26% decreased antibacterial substances and aggravated inflammatory responses of above three immune organs; (2) under the condition of reducing protein level in diet, 0.8-1.2% ETSP supplementation reversed these above adverse effects on immune function of above three immune organs; (3) suitable ETSP supplementation-decreased inflammatory responses were partly associated with [IκB kinase ß (IKKß)/inhibitor of κBα (IκBα)/nuclear factor kappa B (NF-κB) p65 and p52 or NF-κB p65] signaling and [target of rapamycin (TOR)/(S6K1, 4E-BP)] signaling in above three immune organs. (4) On the basis of C3 content (head kidney), C4 content (spleen) and skin hemorrhage and lesion, the optimal ETSP supplementation levels in low protein diets were estimated to be 1.48%, 1.61% and 1.03%, respectively. In summary, ETSP supplementation in low protein diets improved immune function of head kidney, spleen and skin in on-growing grass carp.

Effect of enzymatic hydrolysate of cottonseed protein supplementation on growth performance and intestinal health of nursery pigs in Thailand.

This study investigated the effects of enzymatic hydrolysate of cottonseed protein (EHCP) supplementation on the growth performance and intestinal health of nursery pigs in Thailand. A total of 180 newly weaned piglets were randomly allocated to 3 groups with 6 replicates in each group and 10 piglets per replicate. Nursery pigs were fed three diets containing 0, 1%, and 1.5% EHCP for 28-63 days of age. The results indicated that 1% EHCP supplementation increased average daily feed intake (ADFI) and average daily gain (ADG) and decreased feed conversion rate (FCR) in the numerical, suggesting that appropriate EHCP supplementation could numerically improve growth performance of nursery pigs in Thailand. Moreover, 1% EHCP supplementation significantly decreased intestinal crypt depth and diarrhea incidence and increased intestinal villus height to crypt depth ratio and fecal consistency, suggesting that optimum EHCP supplementation could improve intestinal morphology and decreased diarrhea incidence of nursery pigs in Thailand. Furthermore, 1% EHCP supplementation significantly improved intestinal glutathione (GSH) level and superoxide dismutase (SOD) activity and indicated that optimal EHCP supplementation could improve intestinal antioxidant capacity of nursery pigs in Thailand. Optimum EHCP supplementation numerically increased growth, significantly decreased diarrhea incidence, significantly improved intestinal morphology and antioxidant capacity of nursery pig in Thailand.

Effects of graded levels of dietary methionine hydroxy analogue on immune response and antioxidant status of immune organs in juvenile Jian carp (Cyprinus carpio var. Jian).

Immune response and antioxidant status of immune organs in juvenile Jian carp (Cyprinus carpio var. Jian) fed graded levels of methionine hydroxy analogue (MHA) (0, 5.1, 7.6, 10.2, 12.7, 15.3 g kg(-1) diet) for 60 days were investigated. Results indicated that head kidney index, spleen index, red and white blood cell counts significantly increased with increasing MHA levels up to a point (P < 0.05), whereupon decreased (P < 0.05). Glutathione reductase activity in head kidney and spleen, anti-hydroxy radical and glutathione-S-transferase activities in spleen, catalase activity and GSH content in head kidney significantly increased by MHA supplement, while malondialdehyde content, anti-superoxide anion, superoxide dismutase, glutathione peroxidase activities in head kidney and spleen, protein carbonyl content and catalase activity in spleen, anti-hydroxy radical activity in head kidney significantly decreased by MHA supplement. However, protein carbonyl content and glutathione-S-transferase activity in head kidney, GSH content in spleen remained unaffected. After 60-day feeding trial, a challenge study was conducted by injection of Aeromonas hydrophila for 17 days. Results showed that survival rate, leukocytes phagocytic activity, lysozyme activity, acid phosphatase activity, total iron-binding capacity, haemagglutination titre, complement 3, 4 and immunoglobulin M contents significantly increased by optimal dietary MHA supplement (P < 0.05). These data suggested that MHA affected antioxidant status of immune organs and promoted immune response in juvenile Jian carp.

Therapeutic effects of combined enteral nutrition with Tripterygium Wilfordii poly-glycoside in remission induction of active adult Crohn's disease / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the potential role of enteral nutrition (EN) combined with Tripterygium Wilfordii Poly-glycoside (TWP) for remission induction of active adult Crohn's disease (CD).</p><p><b>METHODS</b>Clinical data of 62 adult patients with active CD treated with EN and TWP in combination (n = 42) or TWP alone (n = 20) from March 2001 to September 2008 were retrospectively analyzed. All the patients had a Crohn's Disease Activity Index (CDAI) > 150 and < 450. In TWP group, subjects received TWP tablets (1.0 - 1.5 mg x kg(-1) x d(-1)) with uncontrolled diets; while in the group of combination therapy, the patients were given total enteral nutrition (TEN) through tube feeding in addition to TWP tablets. Clinical response was defined by a decrease of at least 70 points in the CDAI from baseline after treatment, and clinical remission was defined as the absolute value of CDAI (less than 150). Patients' nutritional and disease activity index, such as CDAI score, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), were determined at 0, 4, and 12 weeks after treatment.</p><p><b>RESULTS</b>The ratio of clinical response (78.6% vs. 40.0%, P = 0.003) and clinical remission (69.1% vs. 30.0%, P = 0.004) were both significantly higher in the combined treatment group than in those the TWP group at week 4. At week 12, the clinical response ratio was significantly higher in the combined treatment group (90.5% vs. 65.0%, P = 0.014); the remission ratio was also higher in the combined treatment group (76.2% vs. 55.0%, P = 0.091). The nutritional parameters improved from baseline at week 4 and 12 in the combined treatment group but not in TWP group. At week 4, blood albumin, prealbumin, and transferrin levels was higher in the combined treatment group than those in TWP group (P < 0.05); at week 12, patients in combined treatment group also had significantly higher body mass index (BMI), blood albumin, prealbumin, transferrin and hemoglobin levels (P < 0.05).</p><p><b>CONCLUSIONS</b>Treatment with enteral nutrition and TWP in combination are superior to TWP alone for induction of clinical response and remission in adult Crohn's Disease. This strategy also improves patient's nutritional status and avoids the adverse effects of traditional therapy.</p>
