Methods Seventy patients with colorectal cancer treated in Shanghai Jiao Tong University Affiliated Sixth People′s Hospital South Campus from January 2010 to December 2013 were involved in this survey. They were divided into the control group and the observation group randomly,each group had 35 cases,the control group was treated with chemotherapy only, the observation group was treated with compound matrine injection combine with chemotherapy. The curative effect,life quality and immune function in the two groups were compared. Results The number of complete remission patients in the observation group was 8 cases ( 22. 86%) ,the number of partial remission cases was 16 cases ( 45. 71%) , the effective rate was 68. 57%, while the control group had 4 cases of complete remission (11. 43%),11 cases of partial remission (31. 43%),the effective rate was 42. 86% (Z=-2. 259,P=0. 024) . In the observation group,life quality was significantly improved in 10 cases (28. 57%),improved in 19 cases ( 54. 29%) ,the effective rate was 82. 86%,while in the control group,life quality was significantly improved in 4 cases ( 11. 43%) ,and improved in 10 cases ( 28. 57%) ,the effective rate was only 40%. The improvement rate of the two groups was statistically significant ( Z=-3. 497,P=0. 000) . Before treatment,the immune function indexes of patients in the two groups were close ( P>0. 05) ,after treatment,the immune function in both groups were significantly improved,CD3+,CD4+,CD4+/CD8+ levels of patients in the observation group were higher than those in the control group,while the CD8+ level in the observation group was lower than that of the control group ( t=-3. 968,P=0. 000;t=-5. 351,P=0. 000;t=-5. 474,P=0. 000;t=6. 407,P=0. 000) . The follow?up time of the two groups was 36 months. After 36 months,the survival rates of the observation group and the control group were 85. 7% (30/35) and 80. 0% (28/35) respectively,and the difference was not statistically significant (χ2=0. 402,P=0. 526) . Conclusion Compound matrine injection combined with chemotherapy can significantly improve the clinical efficacy of elderly patients with colorectal cancer,improve the immune function and quality of life,it is worthy of clinical application.

Objective To observe the implementation of national food safety standard for “Iodine Concentration in Edible Salt”(GB 26878-2011) and its effectiveness on iodine nutritional status of key populations. Methods Information of iodine concentration in edible iodized salt of various provinces (autonomous regions and municipalities, including Xinjiang Production and Construction Corps) was collected using Baidu Searching Engine through the establishment of key words. Sal t samples were collected in Tianjin City and Aksu Region of Xinjiang , and the salt iodine concentration in both places was 30 mg/kg. In Tianjin, Hongqiao, Tanggu and Hangu, Beichen were selected as representatives of the downtown areas, the coastal areas and the suburbs, respectively and counties of Baodi and Ji were iodine deficiency areas in history. Sampling work was carried out from August 2012 to March 2013 in Tianjin. In Aksu, Yatuoer Township and Charqi Town in Baicheng County, Aotebeixi and Aketuohai Townships in Wushen County were chosen as iodine deficiency areas, and the survey was carried out from January to September 2013 . Random urine samples of school-age children ( 8 - 10 years old ) , pregnant women and lactating women were collected; urinary iodine was measured following the Method for Determination of Iodine in Urine by As3+-Ce4+ Catalytic Spectrophotometry(WS/T 107-2006) and iodine in edible iodized salt was measured following the General Test Method in Salt Industry Determination of Iodideion ( GB/T 13025 . 7-1999 ) . Results Fourteen of the provinces(autonomous regions and municipalities, including the Corps of Xinjiang) chose 25 mg/kg as their iodine concentration in edible iodized salt and 13 provinces chose 30 mg/kg. Besides, there were another 5 provinces providing 30 mg/kg particularly for pregnant women and lactating women while 25 mg/kg for other populations. In Tianjin, the medians of iodine concentration in edible iodized salt were ranged from 24.4 - 32.1 mg/kg in retail stores and 26.4 mg/kg at households. The household coverage rate of iodized salt and the proportion of households using adequately iodized salt were 78.5%(168/214) and 62.6%(134/214), respectively. The median ranges of urinary iodine were 178.2 - 183.9 μg/L in school children, 124.3 - 130.9 μg/L in pregnant women and 72.7 - 109.5 μg/L in lactating women. In Aksu, the medians of iodine concentration in edible iodized salt were 27.1 and 26.5 mg/kg in retail stores and households, respectively. The household coverage rate of iodized salt and the proportion of households using adequately iodized salt were 100.0% (363/363) and 98.9%(359/363), respectively. The median ranges of urinary iodine were 174.8 - 293.0, 154.9 - 230.0 and 135.8 - 239.3 μg/L among school children, pregnant women and lactating women, respectively. The median of iodine concentration in a special edible iodized salt sample reached 49.1 mg/kg, and qualified rate was 0(0/11) in Aksu. Conclusions All provinces , municipalities and autonomous regions ( including the Corps of Xingjiang ) in China have adjusted the iodine content in edible iodized salt in accordance with GB 26878-2011. However, in Tianjin the household iodine concentration in edible salt is lower than the local standards; the household coverage rate of iodized salt and the proportion of households using adequately iodized salt are lower than the national standards; pregnant women and lactating women are at risk of mild iodine deficiency.

Objective:To analyze the feasibility, safety and clinical efficacy of laparoscopic side-to-side jejunoileal anastomosis in the treatment of non-obese type 2 diabetes patients (BMI≤32.5 kg/m 2). Methods:The clinical data of 135 patients who underwent laparoscopic side-to-side jejunoileal anastomosis at our hospital from Jan 2018 to Oct 2018 were retrospectively analyzed. They were followed up for 12 months until the end of Oct 2019. SPSS software was used to compare patients′ fasting blood glucose, glycosylated hemoglobin, c-peptide, insulin, body weight, BMI with the values after 12 months of the surgery, and then evaluate factors affecting the prognosis.Results:135 patients successfully completed laparoscopic side-to-side jejunoileal anastomosis without conversion to open surgery. After 12 months of the operation, the patients′ fasting blood glucose was (5.80±0.18)mmol/L, glycosylated hemoglobin was 5.9%±0.4%, fasting c-peptide was(1.32±0.21) nmol/L, and fasting insulin was (42±54) mU/L ( t=10.654, 12.657, 11.214, 10.698, all P<0.05). The body weight was (72.4±9.9)kg, BMI was( 25.6±2.8)kg/m 2, and the difference was not statistically significant ( t=7.658, 6.958, P>0.05). In patients with preoperative glycosylated hemoglobin controlled below 8% and the duration of T2DM less than 10 years, the chances being cured was better than that of those with glycosylated hemoglobin>8% and the medical history >10 years. Conclusion:Laparoscopic side-to-side jejunoileal anastomosis in the treatment of non-obese type 2 diabetes is effective, safe and reliable.

OBJECTIVETo evaluate the association of colorectal adenoma with metabolic syndrome (MS) and relevant parameters.

METHODSClinical data of 289 subjects who underwent screening colonoscopy in the University of Hong Kong-Shenzhen Hospital from January 2014 to June 2015 were retrospectively analyzed, including 130 normal subjects (normal group) and 159 cases with colorectal adenoma confirmed by pathology(adenoma group). Levels of MS-associated parameters were compared between the two groups, and the association of metabolic diseases with colorectal adenoma was examined.

RESULTSThe gender, smoking and drinking habit, regular physical activity, family history of colorectal cancer, and consumption history of long-term non-steroidal anti-inflammatory drugs were not significantly different between two groups (all P>0.05). As compared to normal group, adenoma group had higher body mass index (BMI) [(23.5±3.2) kg/m(2) vs. (22.7±2.8) kg/m(2), t=1.97, P=0.050], larger abdominal circumference [(83.4±10.3) cm vs. (79.6±13.8) cm, t=2.46, P=0.015], higher serum high-density lipoprotein level [(1.3±0.3) mmol/L vs. (1.2±0.3) mmol/L, t=2.03, P=0.044], and higher serum cholesterol [(5.4±1.0) mmol/L vs. (5.0±1.1) mmol/L, t=2.39, P=0.018]. No significant difference was demonstrated in comparing hip circumference and waist-hip ratio, as well as serum fasting glucose and triglyceride(all P>0.05). Higher incidence of colorectal adenoma was found in subjects with MS [69.8%(37/53) vs. 1.7%(122/236), P=0.017], overweight or obesity [65.1% (56/86) vs. 50.7%(103/203), P=0.025], hypertension [67.3%(37/55) vs. 52.1%(122/234), P=0.046] and hypercholesterolemia [66.7%(64/96) vs. 49.2%(95/193), P=0.005].

CONCLUSIONSMetabolic syndrome increased the risk of developing colorectal adenoma. The mechanism may be related to higher serum cholesterol and high density lipoprotein, which may lead to the elevated catabolism of serum cholesterol. Screening colonoscopy should be performed for patients diagnosed as metabolic syndrome, especially for those with central obesity and hypercholesterolemia, thus early diagnosis and treatment of colorectal adenoma may be available.
