Retrospective analyses were performed for the clinical data of 67 patients with biliary calculi.Among them,laparocholedochoscopy plus holmium laser lithotripsy (n =31) and laparocholedochoscopy (n =36) were performed.As compared with laparocholedochoscopy,early postoperative serum inflammatory mediators of holmium laser lithotripsy were obviously lower,biliary pressure dropped faster and less volatile[(8.5±1.5)-(12.2±4.1) vs.(8.1 ±1.6)-(16.5±4.7) mmHg(1 mmHg=0.133 kPa)],operative duration [(93.5 ± 13.4) vs.(127.6 ± 34.5) min],conversion into laparotomy rate[3％ (1/31) vs.11％ (4/36)],postoperation SIRS rate[23％ (7/31) vs.42％ (15/36)],length of hospital stay [(8.5 ± 3.5) vs.(12.6 ± 3.9) days] and postoperative biliary residual stones rate [0％ (0/31) vs.8％ (3/36)]were also better than.

Objective To compare the clinical effects of 3 kinds of early nutrition channels to the postoperative neonatal congenital esophageal atresia.Methods Nutritional support in different ways,81 cases of congenital esophageal atresia were divided into enteral nutrition group (group A),parenteral nutrition group (group B) and enteral-parenteral nutrition group (group AB).Analysis was conducted according to the general situation and postoperative biochemical parameters.Results There were statistically differences in all conditions (P ＜ 0.01 ) excepted fasting time [ (7.2 ± 9.8 ),(7.1 ± 9.3 ),(7.4 ±9.6) d ] in group A,B,AB,advantages and disadvantages:group AB ＞ group A ＞ group B,the difference was statistically significant (P ＜ 0.05).In group A,B,AB,in addition to C-reactive protein [ (7.0 ± 2.4),(6.4 ± 1.8 ),(6.2 ± 1.3 ) mg/L ],the other of the biochemical differences were statistically significant (P ＜0.01),advantages and disadvantages:group AB ＞group A ＞group B,the difference was statistically significant (P ＜ 0.05).Conclusions Enteral and parenteral nutrition in postoperative neonatal congenital esophageal atresia is more sutiable for food digestion and absorption.It is worth in clinical promotion.

Objective To investigate the expressions of vascular endothelial growth factor-C (VEGF-C) and vascular endothelial growth factor-D (VEGF-D) and their relationship with lymph node metastasis in gastric cancer. Methods Eighty patients with gastric cancer had been admitted to our department from January 2005 to December 2005, including 48 with local lymph node metastasis and 32 without local lymph node metastasis. Ten specimens of normal gastric mucosa from patients with gastric ulcer were used as control. The expression of VEGF-C and VEGF-D in serum and tissues were detected. Results The senun levels of VEGF-C and VEGF-D in patients with gastric cancer were significantly higher than those in the control group (χ2= 8.39, P < 0.05). The positive rate of the VEGF-C expression in the sermn of patients with gastric cancer was influenced by the lymph node metastasis (χ2 = 7.01, P < 0.05). The positive rates of the expressions of VEGF-C and VEGF-D in the gastric cancer tissue were 53% (42/80) and 63% (50/80), which were significantly higher than those in the normal gastric mucosa (χ2 =6.44, 6.58, P <0.05). The positive rate of the VEGF-C expression in the tissue of patients with gastric cancer was influenced by the lymph node metastasis (χ2=11.25, P <0.05). Conclusions The expression of VEGF-C is closely related to lymph node metastasis of gastric cancer. The serum levels of VEGF-C can be used as biologic markers in detecting lymph node metastasis of gastric cancer preoperatively.

Aim To study the molecular mechanism of Raptor in the migration and invasion of breast cancer cells and provide the clinical theory basis for prevention of breast cancer invasion and metastasis.Methods Western blot was used to detect the expression of Raptor protein in MCF-7 cells and MDA231 cells.The siRNA plasmids were used to transfect MDA231 cells.At the same time,the plasmid pcDNA3.1-Raptor was transfected into MCF-7 breast cancer cells.And Western blot was used to analyze the protein expression level of E-cadherin and Vimentin.Transwell was used to test the ability of invasion.Nucleus mass separation experiment was used to test the expression of Snail.Results The expression of Raptor protein in MDA231 cells was higher than in the MCF-7 cell.When the control group of Scr/MDA231 cells compared with siRaptor/MDA231,Raptor protein expression was decreased obviously after plasmid transfection interference,accompanied by reduction of Vimentin protein expression and increase of E-cadherin protein expression.Compared with MCF-7/Con,Raptor protein expression significantly increased in MCF-7/Raptor,accompanied by increase of Vimentin protein expression and reduction of E-cadherin protein expression.The number of cells through the artificial basilemma Transwell in siRaptor/MDA231 cells was significantly reduced(P<0.05),and the number of cells through the Transwell chambers artificial basilemma was significantly increased in MCF-7/Raptor(P<0.05).Nucleus mass separation experiment results showed that the expression of Snail decreased obviously in the siRaptor/MDA231 than in the Scr/MDA231,however,the expression of Snail was obviously higher in the MCF-7/Raptor.Conclusions Raptor can promote the occurrence of EMT in breast cancer,thus it promotes invasion and metastasis of breast cancer.

Objective : To explore the association of dietary niacin intake and metabolic syndrome ( MS ) and its components among adults in Zhejiang Province, so as to provide the reference for dietary intervention of MS. Methods: Using the multi-stage cluster random sampling method, the permanent residents aged 18 years and above were selected and investigated by a questionnaire developed by China Center for Disease Control and Prevention. Their waist circumference, blood pressure, glucose and lipid were measured. The daily dietary niacin intake of each person were calculated by "24-hour dietary review for 3 consecutive days", and divided into Q1, Q2, Q3 and Q4 groups according to quartiles. The multivariate logistic regression model was used to analyze the association of niacin intake with the risks of MS and its components. Results: Among 2 438 participants, 871 cases with MS were detected, with a detection rate of 35.73%. The multivariate logistic regression analysis showed that compared with niacin intake Q1 group, Q2 ( OR=0.741, 95%CI: 0.561-0.978 ) and Q4 group ( OR=0.679, 95%CI: 0.487-0.947 ) had a lower risk of MS, Q2 ( OR=0.688, 95%CI: 0.516-0.919 ) and Q4 group ( OR=0.678, 95%CI: 0.479-0.960 ) had a lower risk of abdominal obesity, Q4 group ( OR=0.721, 95%CI: 0.536-0.969 ) had a lower risk of hyperglycemia. Further stratificating by gender, compared with niacin intake Q1 group, Q2 ( OR=0.664, 95%CI: 0.453-0.972 ) and Q3 group ( OR=0.646, 95%CI: 0.432-0.965 ) in women had a lower risk of MS, Q2 (OR=0.667, 95%CI: 0.460-0.967) and Q3 group ( OR=0.607, 95%CI: 0.408-0.902 ) had a lower risk of abdominal obesity; Q2 group ( OR=1.836, 95%CI: 1.202-2.805 ) in men had a higher risk of low high-density lipoprotein cholesterol. Conclusion Niacin intake is associated with an increased risk of MS, abdominal obesity and hyperglycemia.

Objective:To observe the therapeutic effect of microwave ablation combined with anhydrous ethanol for cystic thyroid nodules.Methods:From Jan. 2019 to Dec. 2019, 56 patients with thyroid cystic nodules (≥2cm) underwent ultrasound guided thyroid cystic nodule ablation in Department of Thyroid and Breast Surgery, Nanjing Hospital of Traditional Chinese Medicine. According to different ablation methods, the patients were divided into microwave ablation combined with anhydrous ethanol group and microwave ablation group. There were 36 cases in microwave ablation combined with anhydrous ethanol group and 20 cases in microwave ablation group. The volume reduction rate of thyroid nodules, the incidence of postoperative complications and the changes of thyroid function were compared between the two groups after treatment. Statistical analysis were performed using SPSS, version 21.0, the mean±SD deviation ( ± s) was used to describe the statistics, t-test was performed, and the adoption rate of counting data (%) was expressed by χ 2 test. The difference was statistically significant with P<0.05. Results:The nodule volume reduction rates of the microwave ablation combined with anhydrous ethanol group and microwave ablation group were (49.86±6.78) % vs (22.84±1.88) %, (67.57±5.84) % vs (47.25±7.09) % and (75.70±4.51) % vs (71.14±4.65) % at 3 months, 6 months and 12 months after operation, respectively. There was significant difference between the two groups ( P<0.001) . The incidence of postoperative complications in the two groups was 38.89% and 45.00% respectively, and there was no significant difference between the two groups ( P>0.05) , and all complications were cured within 2 months. There was no significant difference in thyroid function (T3, T4, FT3, FT4, TSH) between the two groups before and 12 months after operation ( P>0.05) . Conclusions:Microwave ablation combined with anhydrous ethanol is more effective in treatment of cystic thyroid nodules (≥2cm) than microwave ablation alone. It can significantly improve patients’symptoms and nodule volume reduction, and does not affect thyroid function. It can be used as a recommended option for treatment of cysticthyroid nodules.
