Nutrition support includes three parts: supplementation, support, and therapy. When? and how? to use nutrition support which should be related with clinical outcome of the patients. Parenteral nutrition became widely accepted in the States since the presentation at American College of Surgeons Congress 1967 by Dudrick et al. More detail study of baby growth and development receiving all nutrients exclusively by vein from Wilmore et al 1968. In China, it was Jiang et al reported the clinical applications of parenteral nutrition at Surgical Congress of Chinese Medical Association 1978. Enteral elemental diet and parenteral nutrition for intestinal fistulae illness by Jiang et al 1979 which enrolled by Medline. Although nutrition support has become a standardized technology in China, but evidences on improving the patients' outcomes were still insufficient. After Kondrup et al estsblished Nutritional Risk Screening 2002 tool, the nutrition support could use an evidence-based approaching with outcome. One prospective cohort study based on hospitals in Baltimore and Beijing, using Nutrition Risk Screening 2002 as the tool, have evaluated the impact of nutritional support (both parenteral and enteral nutrition) on the infective complications among patients at nutritional risk and demonstrated that the overall incidence of complications was significantly lower in patients who had received nutritional support, which was achieved mainly due to the decline of the incidence of infective complications. Therefore, support with appropriate nutrients being necessary for patients at nutritional risks or already with malnutrition. However, more cohort studies and randomized controlled studies with larger samples are still required.

Objective To analyze the treatment effect and factors affecting the prognosis in young people of papillary thyroid carcinoma (PTC).Methods A total of 69 PTC patients were reviewed retrospectively in Sun Yatsen University Cancer Center from Dec 1996 to Oct 2005.The prognostic status were compared using the Kaplan-Meier methods,the factors were analyzed by Log-rank test and the multiple factors were estimated by the Cox regression models.Results There were 26 males and 43 females.The median age was 24 years (mean:23.1 years).The average follow-up time was 113 months ranging from 73 to 174 months.20.3％ patients (14/69) experienced recurrence during follow-up time and 1.4％ patient (1/69) died.All the patients received levothyroxine after operation.The 10 year disease-free survival (DFS) rate of patients with or without extra thyroidal extension (ETE) of PTC was 29.6％ and 80.1％,respectively (P ＜ 0.01).Multivariate analysis showed that young PTC people with ETE had a worse prognosis (P =0.004).Conclusions Young papillary thyroid carcinoma patients had a favorable outcome.Surgical procedure was the first choice for this kind of patients.ETE was an independent factor for the recurrence of young PTC patients.

From August 6 to 8, 2010, the 23 rd "Nutritional risk, malnutrition, nutritional support, outcome, and cost-effective" workshop was held in Beijing. There were 30 participants from Beijing, Tianjin,Chongqing, Chengdu, Kunming, Guiyang, Guangzhou, Songyuan, Weifang, Guilin, Urumqi, Qingdao, Yueyang, and Qinhuangdao. The workshop has 2 sections.

Section 2: Discuss two protocols for cohort study and for randomized clinical trial (RCT). The cohort study is to continue the investigations of the impact of nutritional support for inflammatory bowel disease (IBD) on outcome and cost/effectiveness, and the RCT protocol is to plan a new protocol about the impact of fish oil on postoperative outcome and cost/effectiveness. The second protocol also asked Professor Kondrup to join with as the co-principal investigator. At the pilot period, the fish oil study is an open RCT because the costs of nutrients need to be paid by patients himself (herself). To apply the support for nutrients is on the schedule. The 24th workshop will bo held on December 17-19, 2010 in Beijing.

Objective To establish the methods for controlling quality of Yiqi Congming Pills, and to improve the quality standard for the pills. Methods Yiqi Congming Pills were sampled from the products of 3 mainpharmaceutical companies in China market, 2 batched from each company. Radix Puerariae, Radix Astragali, Fructus Viticis, Cortex Phellodendri Chinensis, Radix Codonopsis in Yiqi Congming Pills were observed under microscope for microscopic identification. Radix Astragali, Rhizoma Cimicifugae, Radix Paeoniae Alba, and Cortex Phellodendri Chinensis were identified by thin-layer chromatography (TLC) for qualitative differentiation. The contents of puerarin and paeoniflorin in Yiqi Congming Pills were determined by high performance liquid chromatography(HPLC). Results The microscopic characteristics of Radix Puerariae, Radix Astragali, Fructus Viticis, Cortex Phellodendri Chinensis, Radix Codonopsis in the pills were obvious and were easy for discrimination. The spots in thin-layer chromatography (TLC) chromatograms of Radix Astragali, Rhizoma Cimicifugae, Radix Paeoniae Alba, and Cortex Phellodendri Chinensis were clear without interference of negative reference. Puerarin had a good linearity in the range of 0.00112~3.50676μg, and the average recovery rate was 98.2%(sR=1.4%, N=9 ). Paeoniflorin had a good linearity in the range of 0.00333 ~ 3.328 μg, and the average recovery rate was 98.4%(sR = 1.8%, N = 9). Great differences existed in the contents of puerarin and paeoniflorin of Yiqi Congming Pills from the three pharmaceutical companies. Conclusion The established qualitative and quantitative methods are of accuracy, credibility and repeatability, and are effective for controling the quality of Yiqi Congming Pills.

Objective To evaluate the impact of fish oil (ω-3 fatty acids) parenteral nutrition (PN) on outcomes for non-ICU postoperative patients.Methods PubMed,Embase,Cochrane,China National Knowledge Infrastructure (CNKI) and Wanfang Database etc.were searched to retrieve the eligible studies published from January 2010 to June 2016.The studies included were randomized controlled trials (RCTs) that evaluated the effects of supplementation of fish oil (Omegawen) in PN regimens for postoperative patients on clinical outcomes.The methodological quality assessment was based on Jadad scale and Schulz allocation concealment tool.Meta-analysis was conducted by RevMan 5.3 software.Results 19 RCTs,1 170 surgical patients,were included.Meta-analysis indicated that short-term fish oil supplementation significantly reduced the incidence of infectious complications [RR =0.44,95％ CI (0.31,0.64),P ＜0.000 1] and shortened the length of hospital stay [MD =-0.85,95％ CI (-1.67,-0.03),P=0.04],while with no significant effect on mortality [RR =0.42,95％ CI (0.07,2.63),P =0.36] and total expenditure of hospitalization [MD =-216.60,95％ CI (-718.94,285.75),P =0.40].Sensitivity analysis showed similar results.Conclusion According to existing evidence,fish oil in PN for surgical patients could reduce the incidence of postoperative infectious com-plications and shorten the length of hospital stay.

Objective To study the effects of the monoclonal anti idiotypic antibody NP30 active immunization on egg granuloma formation and hepatic fibrosis in Schistosoma japonicum infection. Methods ICR mice were actively immunized with NP30 100 ?g ?3 ip. every 10 days while the mice in control group were injected with SP2/0 ascites ip. simultaneously. After cercariae challenging,the mice were killed at the 4th, 8th,12th, 16th, 20th and 24th week, respectively.Mouse livers were removed and stained histochemically with VG and subjected to immunohistochemical assay of collagen type Ⅰ,Ⅲ and fibronectin(FN).The volume of egg granulomas and the content of collagen type Ⅰ,Ⅲ and FN were determined quantitatively by NYD 1000 Image Analysis System. Results The volume of egg granulomas in NP30 immunized group was much smaller than that of control group from the 12th week after cercariae challenge. The cellular components of egg granulomas in NP30 immunized group were significantly different from those of the control group,exhibiting two types of atypical egg granulomas were found.VG stain revealed that the average optical density of collagen in hepatic granulomas of experimental group was lower than that of control group.Immunohistochemical assay revealed that the contents of collagen type Ⅰ,Ⅲ and fibronectin in egg granulomas of experimental group were lower than those of control group. Conclusion NP30 vaccination may induce both cellular and humoral protective immunity to modulate egg granulomas and suppress liver fibrosis of schistosomiasis japonica.

Objective To investigate the predictive value of abnormal multiples of the median (MoM) of second trimester maternal serum triple screening (STMSTS) markers for adverse pregnancy outcomes.Methods 16 000 singleton pregnancies at 15+0 to 20+6 weeks' gestation who underwent STMSTS between July 2010 and January 2013 in the First Hospital of Jilin University were recruited.Maternal serum AFP,free β-hCG (F-β-hCG) and unconjugated estriol (uE3) levels were measured using time-resolved fluoroimmunoassay,and then convened to MoM.LifeCycle 3.2 software was used to calculate risk,and a risk value greater than 1 in 270 or 1 in 350 was considered as high risk for trisomy 21 syndrome (Down syndrome,DS) and trisomy 18 syndrome (Edwards syndrome,ES),respectively.MoM of AFP more than 2.5was considered high risk for open neural tube defect (ONTD).Amniocentesis and karyotyping,ultrasound screening were advised for high risk women.AFP,F-β-hCG higher than 2.0 MoM or uE3 lower than 0.5MoM was considered as abnormal,respectively.The MoM of STMSTS marker between women with adverse pregnancy outcome and with normal outcome was compared.Results (1) The median MoM of AFP,F-β-hCG and uE3 was 0.91 MoM,0.94 MoM and 1.05 MoM,respectively.Of the 16 000 pregnant women,there was no statistical difference in the median MoM of triple screening marker at different weeks of gestation (P＞0.05).The positive rate of DS,ES and ONTD in women ≤35 years old (n=14 972) was 4.03％ (603/14 972),0.36％(54/14 972) and 0.29％(44/14 972) respectively.And in women＞35 years old(n=1 028),the positive rate was 24.51％ (252/1 028),1.95％ (20/1 028) and 0.78％ (8/1 028),respectively.There was a statistically significant difference of positive rate between the two groups(P＜0.05).(2) 9 cases of DS,1 case of ES and 1 ease of ONTD were found in the high risk group,and 2 cases of DS in the low risk group.The detection rate of DS,ES and ONTD was 9/11,1/1 and 1/1 respectively; and the positive predictive value was 1.05％(9/855),1.35％(1/74) and 1.92％(1/52),respectively.(3)The incidence of adverse outcome (group 1) was 1.49 ％(239/16 000).7 760 pregnant women in this study were healthy during pregnancy,so were their fetuses (group 2).There were significant differences in the age at delivery,body weight and markers' MoM of STMSTS between the two groups(P＜0.01).(4) In group 1,the rate of abnormal MoM of AFP or F-β-hCG was 7.95％(19/239) and 23.85％ (57/239),and the abnormal rate of MoM of uE3 was 4.18％(10/239).The rate of two abnormal MoM of markers was 5.02％(12/239); the rate that all three MoM were abnormal was 0.84％(2/ 239).However,in group 2,the rate of two abnormal MoM of markers was 0.14 ％(11/7 760); and the rate that all three MoM were abnormal was 0.There was a significant difference of abnormal MoM of maternal serum marker between the two groups (P＜0.01).Conclusions There is a relationship between abnormal marker of STMSTS and adverse outcomes.STMSTS show a high value in the detection of DS,ES and ONTD.

Objective To evaluate the prognostic value of intraoperalive detection in rib bone marrow micmmetastasis(BMMs)of patients with non-small-cell lung cancer(NSCLC)and the relationship between the micROmetast ases and clinicopathologic factors.Method From April 2004 to May 2007,146 patients undergoing surgical treatment for NSCLC were prospectively investigated for the presence of BMMs by the immunohistochemisury method.Remits 30.82%(45/146)of NSCLC patients were detected with BMMs,15(33.33%)patients developed remote metastases of the 45 patients with BMMs,14(13.86%)patients developed metastases of the 101 patients without BMMs.Patients with BMMs demonstrated an earlier metastasis and a lower survival rate compared with patients without BMMs(P＜0.05).There Was trend for ahigher frequency and the occurrence of BMMs changed with tumor stages and the histologic differentiation of the tumor.No relationship was found between BMMs and age,T grade,as well as tumor dimension.Conclusions The detection of BMMs can predict the prognosis of NSCLC patients and identifies patients withNSCLC who are at significantly increased risk for metastasis and survival,which may be useful in evalnatingpatients for adjuvant treatment

Objective To explore the effective methods of increasing the symmetry of blepharoplas-ty. Methods The two eyelids were synchronously incised, and equal amount of musculi dormitator and fat tissues removed. Firstly, suture at the golden point of intersection for one eyelid, then suture the same point on the other one, and carefully compare the symmetry of both eyelids. Results All the 31 patients, except 1, were satisfied with the results of the symmetry with same height and length. Conclusion Syn-chronously incising the two eyelids and suturing at the symmetrical points by comparison can evidently in-crease the symmetry of blepharoplasty.

Objective To evaluate the prediction value on distant metastases of fib bone marrow micrometastases (BMM) of patients with non-small lung cancer ( NSCLC ). Methods From January 2003 to March 2006, 168 patients undergoing surgical treatment for NSCLC were prospectively investigated for the presence of BMM by using immnnohistochemistry. The sensitivity and specificity of the rib bone marrow micrometastases technique were also calculated. Receiver operating characteristic curve (ROC curve)was drawn according to data. Results Occult BMM were detected in 29.76 %(50/168) of patients with NSCLC. 15(29.76 %) patients developed metastases in the 50 patients with BMM and 15 (12.71%) patients developed metastases in the 118 patients without BMM. The sensitivity and the specificity of the technique was 61.54 % and 79.84 %. The false negative rate was 38.46 % and the false positive rate was 20.16 %. The positive predictive value, negative predictive value and Youden' s index were 87.5 %, 93.33 %, 74.33 % respectively. Conclusion The detection of BMM could predict the distant metastases of non-small lung cancer patients through receiver operating characteristic curve evaluation, however, the detecting sensitivity should be improved.
