Objective To investigate the clinical application of early postoperative enteral nutrition in patients undergoing colon cancer operation.Methods 90 patients suffering from colon cancer were randomly divided into the enteral nutrition group,indwelling stomach tube group and the control group.The control group was given conventional treatment and the indwelling gastric tube group was received postoperative intermittent clamping of stomach tube and enteral nutrition.Moreover,patients in the enteral nutrition group were pulled out the tube on the first postoperative day while giving enteral nutrition.All patients were observed for exhaust defecation time,length of hospital stay postoperative and nutrition indicators.Results Exhaust defecation time,length of hospital stay postoperative had significant difference among three groups.Indwelling stomach tube group set minimum length of stay and first passage of flatus and defecation in the three groups [the enteral nutrition group:(50.07±11.59) h,(76.75±27.37) h,(10.1 1±1.57) d,the control group:(62.03±12.31) h,(90.67±25.64) h,(11.80±1.83) d,indwelling stomach tube group:(43.53±11.94) h,(61.17± 22.67) h,(8.70±1.53) d (P ＜ 0.05)].The levels of hemoglobin and plasma albumin one week after operation were statistically lower than pre-operation,while that the level of these nutrition indicators were higher in indwelling stomach tube group compare to control group (all P ＜ 0.05).The same result was observed between enteral nutrition group and control group.Whereas,the change of nutrition indicators between the enteral nutrition group and the control group was not statistical significant (P ＞ 0.05).Conclusion Indwelling stomach tube combined with enteral nutrition is a reasonable choice for patients after colonic cancer surgery.

This paper presents the results of the gross dissection and the histologic observation on the thyroid and parathyroid glands of Rhinopithecus. Specimens used in the studies are composed of R. roxellanae (1 (?), subad.), R. bieti (2 ♀♀, ad.; 1 ♀,juv.) and R. brelichi(2(?)(?),ad.). Besides the position and shape of the gross anatomy of the thyroid and parathyroid glands, attention was paid to the cellular types of the parathyroid glands. Material used for the histologic investigation is stained with HE and the modified Mallory-Azan methods and observed under the light microscopy. The principal results are summarized as follows:1. The thyroid gland consists of two lateral obes. The dimension of the gland measured 18.0?9.0, 15.0?8.0 and 14.0?6.0 mm. in bieti;23.0?9.0 mm. in roxellanae; 25.0?9.0 and 30.0?1.0 mm in brelichi; and one isthmus measures 3.0?10.0, 2.0?10.0 and 2.0?6.0 mm. in bieti; 4.0?6.0 mm. in roxellanae; 5.0?12.0 and 5.0?14.0 mm. in brelichi.The total weight of the gland is 1.0, 0.5 and 0.3g in bieti; 0.9g in roxellanae; 0.9 and 1.8g in brelichi.The isthmus connects the lower edges of two lateral lobes. There is no pyramidal lobe.2. The blood supply is derived from the superior thyroid arteries. There are no inferior thyroid arteries in three kinds. The thyroid venous drainage is by the superior and inferior thyroid veins, there is no median thyroid vein.3. The sizes and shapes of the thyroid vary with species. Each animal possesses two parathyroid glands, one of each side, but their position is also variable in the different animals.4. The follicular epithelium of the thyroid contains two cellular types, viz. the typical follicular epithelial cells and C cells.5. The parathyroid gland of Rhinopithecus is histologically similar to that of Macaca mulatta and man, which contains four basic cellular elements. There is an intermediary cellular type probably a variant of the oxyphil cells.6. Grey blue granules are present in the pale oxyphil cells of the parathyroid glands of both brelichi and bieti.7. There are less oxyphil cells among the parenchymal cells of the parathyroid gland in the subadult roxellanae than in both bieti and brelichi.

Objective To investigate the safety and clinical outcome of laparoscopic resection of rectal cancer. Methods The clinical data of 347 patients with rectal cancer who were admitted to the Shanxi Tumor Hospital from May 2004 to July 2008 were prospectively analyzed. Of all the patients, 343 met the inclusion criteria,and they were randomly allocated to laparoscope group (n = 169) and open group (n= 174). The diameter of the tumors, number of lymph node dissected, length of rectum resected, morbidity, the mean operation time, number of patients receiving blood transfusion, time to out-of-bed activity, first flatus, bowel movement and liquid diet were observed. All data were analyzed using the t test and chi-square test. The survival rate was calculated using the Kaplan-Meier method. Results The diameter of the tumors, number of lymph node dissected, length of rectum resected and number of patients receiving blood transfusion in the laparoscope group were (4.3 ± 1.3 ) cm, 7 ± 5,(19.1±2.2)cm and 4, and they were (4.2±1.3)cm, 7 ±5, (19.0±2.3)cm and 8 in the open group,respectively, with no significant difference between the two groups ( t = 0. 629, - 0. 726, 0. 562, x2 = 1. 264,P ＞0.05). The mean operation time in the laparoscope group was 19 minutes longer than that in the open group (t = 7. 904, P ＜ 0.05 ). The time to out-of-bed activity, first flatus, bowel movement and liquid diet in the laparoscope group were 0.6, 0.3, 0.3 and 0.6 days earlier than those in open group( t = - 6. 392, - 3.581, - 3. 802,- 3. 493, P ＜ 0.05 ). There were no significant differences in postoperative infection, anastomotic leakage, intestinal obstruction and deep vein thrombosis between the two groups ( x2 = 0. 236, 0. 354, 0. 000, 0. 000, P ＞0.05). A total of 167 patients in the laparoscope group and 172 patients in the open group had been followed upuntil 1 may, 2010. The 1-, 2-year survival rates were 94.0% and 82.6% in the laparoscope group and 95.3% and 91.2% in the open group. There was no significant difference in the 2-year survival between the two groups (x2 =0.541, P ＞0.05). The survival time of the patients in the laparoscope group and open group were 55.9 and 57.9 months, respectively. Conclusions Laparoscopic surgery is safe and feasible for patients with rectal cancer, with quick recovery after the operation.

A methodology for preparing and certifying the reference material of 3-amino-2-oxazolidinone(AOZ) in eel muscle lyophilisates was presented. Furazolidone was accessed to eel by dipping fish in pond with furazolidone solution at a dosage of ca 0.16 mg/L. With the metabolism of furazolidone in eel, the muscles contain a certain concentration of AOZ as furazolidone metabolite was obtained. Lyophilization of the muscles was performed in one batch and 400 bags of samples were obtained by the procedure of homogenation, cryodesiccation and irradiation. The homogeneity and stability of the sample was examined. The value of the chemical constituent of the sample was certified through the collaborative analysis program participated by 11 laboratories using isotope dilution liquid chromatography-tandem mass spectrometry, and the uncertainty assessment was performed. The reference materials have been approved as certified reference materials by AQSIQ, China (State General Administration of the People′s Republic of China for Quality Supervision and Inspection and Quarantine) in 2009 after one year of trial period. The serial numbers is GBW(E)100180.

Objective To investigate the diagnosis and treatment of anorectal malignant melanoma,in order to regulate surgical methods and explore multi-modality treatment.Methods Clinical pathological features,diagnosis and treatment procedures of 38 patients with anorectal melanoma were reviewed,and their correlation with prognosis were analyzed.Results In 38 patients,10 of them were male and 28 were female,with the mean age of 58.7 years old (ranged 28-75 years old).28 patients underwent abdominoperineal resection,10 patients underwent wide local excision.The 1-,3-,and 5-year disease-free survival rates were 64.9 ％,18.5 ％ and 5.7 ％,respectively.The 1-,3-,and 5-year overall survival rates were 85.8 ％,24.1％ and 6.4 ％,respectively.Tumor thickness (≥ 1.51 rm) and tumor diameter (≥3 cm) were associated with lymph metastases (x2 =13.093,4.449,P =0.011,0.020),tumor thickness was also associated with distant metastases (x2 =11.965,P =0.018).According to the Kaplan-Meier method,comprehensive treatment after surgery had significant effects on disease-free survival (x2 =7.441,P =0.006).Tumor thickness,lymph metastases,and clinical staging had significant effects on overall survival (x2 =16.741,16.474,16.775,P =0.002,0.000,0.000).Cox proportional hazards model indicated that comprehensive treatment after surgery was the independent prognostic risk factors of disease-free survival (95 ％ CI 1.420-17.621,P =0.012).Tumor thickness and lymph metastases were the independent prognostic risk factors of overall survival (95 ％ CI 0.250-0.949,1.033-2.573,P =0.035,0.036).Conclusion Early detection,reasonable surgical procedure,generalized systemic focus on immunotherapy treatment are the key to improve quality of life and prolong the survival time of anorectal malignant melanoma patients.

Objective To investigate maternal risk factors for fetal congenital heart diseases (CHD). Methods A case-control study was conducted on 16 645 pregnant women who underwent cardiovascular malformation screening for fetal cardiovascular system,whose pregnancy outcomes were recorded,and whose newborns were scanned by an echocardiography in Peking University People's Hospital,Haidian,Changping,Mentougou and Daxing Maternal and Child Health Hospital from Nov.2006 to Oct.2009.One hundred and twelve pregnant women whose babies were found to be CHD (40 severe CHD and 72 simple CHD) before or after delivery were taken as study group.Women in control group (n =304) were randomly selected from those pregnant women who had infants without CHD.Logistic regression analysis and x2 test were used to analyze the maternal risk factors for fetal CHD. Results (1) The average age of women whose infants had severe CHD was 28.3 years (21-40 years),and it was 29.9 years (22-39 years) for women whose infants had simple CHD.There were no significant differences between the control group (29.5 years,20-44 years) and the above two groups (t=1.511 and -0.826,P=0.138 and 0.410 respectively).(2) Single factor analysis:during first trimester,the rate of upper respiratory infection (18/39,46.2 ％) and exposure to certain chemicals (13/40,32.5％) of severe CHD group were higher than those of control group [(14.9％ (45/303) and 2.0％ (6/304)] (x2 =22.399 and 62.678,OR=4.895 and 23.753,95％CI:2.419-9.905 and 8.358-67.506,P =0.000 respectively).Compared with control group (0.0％,0/304),the rate of pregnant women with CHD family history in simple CHD group was significantly higher (4.2％,3/72)(Fisher exact test,P=0.007).(3) Logistic regression analysis:maternal upper respiratory infections (OR =5.120,95％CI:2.340-11.206,P =0.000) and exposure to certain chemicals (f)R=23.030,95％CI:7.506-70.665,P=0.000) during first trimester were risk factors for fetal severe CHD. Conclusions Upper respiratory infection and exposure to certain chemicals during first trimester might play important roles in the occurrence of fetal severe CHD.Maternal family history of CHD might associate with fetal simple CHD.
