BACKGROUND: We have previously reported that marine algae polysaccharide derivant can significantly promote bone cell growth.OBJECTIVE: To observe the effect of marin algae polysaccharide derivant in treatment of osteoporosis.METHODS: Sixty female Wistar rats were randomly divided into control group, treatment group and model group. There were 20 rats in each group. The rats in treatment group and model group were respectively treated with retinoic acid to induce osteoporosis. The rats in treatment group were gavaged the marine algae polysaccharide derivant 10 mg/kg, and the rats in model group were gavaged the glucose 10 mg/kg orally for 14 days. Changes of rat femur bone histological examination and histomorphometry parameters were observed.RESULTS AND CONCLUSION: The mean Trabecular Number (Tb.N), the mean Trabecular Thickness (Tb.Th) and the percent Trabecular Area (Tb.Ar%) were significantly decreased in the model group compared with control group. The mean trabecular separation (Tb.Sp) was greatly increased. After intake of marine algae polysaccharide derivant, Tb.N, Tb.Th and Tb.Ar% of the treatment group were significantly more than that of the model group. The Tb.Sp was obviously reduced. These indicate that marine algae polysaccharide derivant can increase bone mass and have a therapeutic and preventional effect on the osteoporosis.

Objective To evaluate the effects of a single preoperative dose of gabapentin on buprenorphine patient controlled intravenous analgesia after modified radical mastectorny. Methods Sixty female patients,ASA physical starus Ⅰ and Ⅱ undergoing modified radical mastectomy under general anesthesia were divided into two groups of 30 each group by random digits table to receive either gabapentin 1200 mg (gabapentin group) or a matching placebo (control group), administered orally 2 h before the induction of anesthesia. Subjects received patient controlled intravenous buprenorphi(n)e analgesia during thepostoperative period. Fifty-three patients finished this study, 28 cases in control group,25 cases in gabapentin group. Postoperative pain (static and dynamic),postoperative nausea and vomiting,anxiety,sedation were assessed by pain visual analogue scale(VAS), four-point ordinal scale, anxiety visual analogue scale, Ramsay sedation scale respectively. Postoperative buprenorphine consumption and time to first patient controlled analgesia were observed. Results Postoperative VAS (static and dynamic) was lower in gabapentin group than that in control group (P ＜0.05). Postoperative buprenorphine consumption was (506.1 ±37.9)μg , time to first patient controlled analgesia was (21.1 ±2.3)min,incidence rate of postoperative nausea and vomiting was 40.0% (10/25), antemetic rate was 12.0% (3/25), grade of anxiety was (28.5 ± 12.1) scores in gabapentin group, (699.8 ± 87.8)μ g, (4.3 ±0.8) min,64.3% (18/28),32.1%(9/28) and (66.3±15.7) scores in control group respectively. There were significant differences between two groups (P ＜ 0.05). Conclusion A single preoperative oral dose of gabapentin 1200 mg can effectively attenuate postoperative pain,reduce the consumption of buprenorphine,decrease the incidence rate of postoperative nausea and vomiting,improve patients' anxiety in patients undergoing modified radical mastectomy under general anesthesia.

Objective To explore the clinical effects of pedicled omentum in preventing anastomotic leakage after resection of colorcctal cancer complicated with intestinal obstruction.Methods The clinicopathologic data and anastomotic leakage rate of 102 patients with colorectal cancer undergoing resection from Dec.2012 to Dec.2015 were analyzed.Results Seven patients in the control group developed anastomotic leakage.Only 1 patient in the experimental group developed anastomotic leakage.The incidence of anastomotic leakage in the control group was 12％,while that in the experimental group was 2％ (x2 =4.250,P =0.039).Of the 7 patients complicating anastomotic leakage in control group,1 died of multiple organ failure,1 was cured with conservative treatment,and 5 were done with diverting stoma.The one leakage in experimental group was cured by conservative treatment.Conclusion Pedicled omentum is useful in the prevention of anastomotic leakage after resection of colorectal cancer in settings of intestinal obstruction.

Objective: To establish a scoring system to predict the risk of anastomotic leakage in patients with rectal cancer older than 60 years. Methods: The study included 995 patients (≥ 60 years) with rectal cancer locating 3-12 cm from the anal verge who underwent anterior resection or intersphincteric resection at the Department of General Surgery, Henan Cancer Hospital from January 2012 to December 2016. Potential risk factors for leakage were subjected to univariate analysis. Multivariate logistic regression analysis was used to identify the independent risk factors for anastomotic leakage. The scoring system was developed based on regression coefficient for each significant risk factor. One point was allocated to the risk factor with a regression coefficient β < 1, and two points were allocated to the risk factor with β > 1. The proposed scoring system was tested by the area under curve (AUC) of the receiver operating characteristic curve (ROC) . Results: Surgery was successfully performed in all 995 patients. The incidence of anastomotic fistula was 4.6% (46/995) . Among these 46 patients, 31 recovered after conventional treatment, and 13 patients underwent transverse colostomy, and 2 died of multiple organ failure. Independent risk factors included age (β = 0.643, OR = 1.902, 95%CI: 1.020 - 3.614, P = 0.048) , body mass index (BMI) (β = 1.218, OR = 3.379, 95%CI: 1.607 - 7.105, P = 0.001) , albumin levels (β = 0.986, OR = 2.681, 95%CI: 1.432-5.021, P = 0.002) , and level of anastomosis from the anal verge (β = 1.395, OR = 4.034, 95%CI: 2.086-7.801, P = 0.000) . The scoring system was created base on coefficient β of the independent risk factors (age≥70 years for 1, BMI≥25 kg/m² for 2, albumin levels < 35 g/L for 1, level of anastomosis from anal verge < 4.0 cm for 2) . All the scores were added up, and all patients were divided into the high-risk group (4-6 points, n=71) and intermediate-low-risk group (0-3 points, n=924) based on the scoring system. The incidence of anastomotic leakage in the two groups was 23.9% (17/71) and 3.1% (29/924) , respectively (χ² = 60.092, P = 0.000) . The AUC of age, BMI, albumin levels, and level of anastomosis from the anal verge were 0.598, 0.591, 0.622, and 0.635 respectively. The AUC of the scoring system was 0.656, which was higher than above parameters with a sensitivety of 0.37 and specificity of 0.94. Conclusions The scoring system is effective and accurate for identifying a subgroup at high risk for postoperative anastomotic leakage in rectal cancer patients over 60 years old.

Objective: To assess the clinical value of neutrophil-to-lymphocyte ratio (NLR) in predicting anastomotic leak of postoperative rectal cancer patients. Methods: The clinical data of 787 rectal cancer patients who underwent anterior resection from January 2014 to December 2017 in Affiliated Tumor Hospital of Zhengzhou University were collected. The postoperative numbers of white blood cell (WBS) on postoperative day (POD)1, 3 and 5 were detected, and the NLR was calculated. The relationship of NLR and the incidence of anastomotic leak was analyzed, and the area under the receiver-operating characteristic (ROC) curves was calculated. The accuracy of postoperative NLR in predicting the incidence of anastomotic leak was evaluated. Results: WBC counts of patients with leak on POD1, POD3 and POD5 were 13.2×10⁹/L, 9.1×10⁹/L and 8.9×10⁹/L, respectively, while those of patients without leak were 12.9×10⁹/L, 9.0×10⁹/L and 8.8×10⁹/L. The WBC count was not significantly different between patients with or without leak (P>0.05). The average NLR values of patients with or without leak were 13.3 and 11.6 on POD1, 10.9 and 7.6 on POD3, 9.3 and 5.3 on POD5, respectively. The NLR values of patients with leak on POD3 and POD5 were significantly higher than those of patients without leak (P<0.05). The cutoff value of NLR on POD3 was 8.6, the sensitivity and specificity of detecting the leakage was 73.2% and 75.6%, respectively, and the area under curve (AUC) was 0.744. The cutoff value of NLR on POD5 was 5.5, the sensitivity and specificity was 69.6% and 75.5%, the AUC was 0.726. The multivariate analysis result showed that NLR >8.6 was an independent factor for anastomotic leak prediction. Conclusion Postoperative NLR on day 3 is useful in predicting anastomotic leak and can decrease the incidence of complication in rectal cancer patients who underwent anterior resection.
