[Objective] To observe the curative effects and the influence of activity of Superoxide dismutase(SOD) and contents of Maleic dialdehyde(MDA) of Qingchangyukui Gel in Rats with Experimental Ulcerative Colitis. [Method]Ulcerative Colitis model was established in Wistar rats by injecting trinitro-benzene-sulfonic acid (TNBS)into anus, and then treated with Qingchangyukui Gel and salisy-lazosulfa-pyridine(SASP) respectively. Isolating the colon and measuring the SOD and MDA after treating for two weeks. [Results]Colon mucous membrane in the model group had serious erosion, ulcer, damaging of glandular organ, high inflammation grade; activity of SOD in model group was significantly lower than in normal group and contents of MDA increased. The other groups, especially in Qingchangyukui Gel group, had different levels of inflammation repairing, ulcer healing, increasing of SOD and reducing of MDA. [Conclusion]TNBS can cause Colon mucous membrane inflammation and ulcer, reducing of SOD and increasing of MDA , which are the typical pathological change of Ulcerative Colitis; the Qingchangyukui Gel has the effects of increasing the activity of SOD and reducing contents of MDA, therefore it can effectively treat the UC rat.

Objective To study the effective evaluation of short peptide enteral nutrition powder in advanced digestive tract cancer. Methods 50 cases of advanced digestive tract cancer were randomly divided into two groups: experimental group(short peptide enteral nutrition powder) and control group(routine treatment). Results Data regarding to nutritional status and immune function (WT/IBW, TSF, MANC, ALB, TRF, PA, lgG, lgM, IgA, C3, CD3, CD4, CD8, CD4/CD8) showed a significant difference between experimental group and control group after two weeks's treatment,as well as between before and after two weeks's treatment in experimental group(P <0.05). Conclusion Short peptide enteral nutrition powder maintenance is beneficial to improve the nutritional status and the immune function of patients with advanced cancer and to promote their life quality.

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.

Objective To investigate the effects of mifepristone on apoptosis and expression of relative genes in early pregnant chorionic villi and decidua Methods The specimen of early pergnant chorionic villi and decidua obtained from 10 cases of requesting temination of pregnancy by curettage, 20 cases of mifepriston contragestation The paraffin sections were used to determine apoptotic cells by TdT mediated dUTP biotin nick end labeling method, to identify bcl 2, bax, fas, fasL and proliferating cell nuclear antigen (PCNA) by immunohistochemistry, to demonstrate fas and fasL mRNA by in situ hybridization Results In normal early pregnant specimens, apoptotic cells were mainly observed in syncytiotrophoblast, but not in cytotrophoblast cells, occationally seen in decidua cells The antigen of bax, fas, fasL were present in syncytiotrophoblast cells and decidua with lower amount While bcl 2 antigen staining was strong in cytotrophoblastic cells and in decidua PCNA protein was present in cytotrophoblastic and decidual cells only In the specimens treated with mifepristone, apoptotic cells were increased in syncytiotrophoblastic cells of villi and visualized in decidua cells The expression of fas, fasL and bax was also higher than that of nomal Conclusions Mifepristone increased apoptosis in syncytiotrophoblastic and decidua cells, but had no effect on the expression of bcl 2 and PCNA

Objective To investigate the levels of serum surfactant protein D (SP-D) and mannosebinding lectin (MBL) in infants with cytomegalovirus (CMV) pneumonia with the severity of disease.Methods A total of 101 hospitalized infants with CMV pneumonia were enrolled from January 2011 to December 2012.These patients were divided as the severe pneumonia group (n =48) and the mild pneumonia group (n =53) according to physical sign of lung and complication.Another 55 infants who were hospitalized in the same period with non-infectious diseases were used as the control group.Serum levels of SP-D and MBL were detected by enzyme-linked immunosorbent assay.Blood gas analyzer was used to measure arterial partial pressure of oxygen (PaO2) of the blood in severe patients.Results The mean serum SP-D levels in the severe pneumonia group [(150.08 ±52.59)ng/ml] and the mild pneumonia group [(109.67 ±31.39)ng/ml] were significantly higher than those in control group [(41.33 ± 16.42) ng/ml] (P ＜ 0.01), and higher in the severe pneumonia group than in the mild pneumonia group (P ＜ 0.01).However, there was no significant difference in serum MBL between all groups (P ＞ 0.05).In severe patients, serum SP-D levels were negatively correlated with PaO2 (r =-0.565, P ＜ 0.01).Conclusion Serum SP-D is associated with the severity of CMV pneumonia, but MBL shows no relation.The serum SP-D levels has an important clinical significance in judgment the sererity of infants with CMV pneumonia.

Objective To investigate the operational timing and manner for the digestive tract reconstruction after Hartmann procedure and the prevention for the postoperative complications in the patients with left colorectal cancer.Methods The data of twenty-four cases with digestive tract reconstruction were analysed retrospectively containing the cause of Hartmann procedure for left colorectal cancer,preoperative evaluation of the digestive tract reconstruction,operation timing,operation manner,postoperative complications and length of hospital stay and so on.Results Three of 24 patients gave up the digestive tract reconstruction due to the results of their distant metastasis detection in the preoperative evaluation.As a commonly manner of digestive tract reconstruction,rectum-sigmoid colon or sigmoid-descending colon end-end anastomosis was used for 17 patients.Meanwhile,ascending colon-sigmoid colon end-side anastomosis was used for 4 patients.The incidence of postoperative complications was 14.29 ％ (3/21),and the mean time of postoperative hospital stay was 10.5 days.Conclusions In patients undergoing Hartmann procedure for left colorectal cancer,adequate assessment of the tumor recurrence and metastasis is necessary.In addition,the optimal timing of surgery should be selected after completion of chemotherapy,and operational manner should be determined by the situation of intraoperative exploration.

ObjectiveTo assess malignant trophoblastic neoplasia with the standards of the clinical stage and prognostic factor scoring system. MethodsThrough assessing the high-risk factors except clinical stages for 223 patients before treatment according to International Federation of Gynecology and Obstetrics(FIGO) scoring system published in 2000, appropriate treatments were selected for the different patients. ResultsForty-three of 78 cases of choriocarcinomas were with high-risk factors, the other 35 cases were with low-risk factors; 7 of 145 cases of invasive moles were with high-risk factors and the others were with low-risk factors. The primary chemotherapy principle was that one agent was used for those patients with low-risk factors and two or multiple-agents were used for those patients with high-risk factors. Among all patients, the one-year, three-year and five-year survival rates were 98.6%,98.1% and 97.1% respectively. No patient died of drug toxicity or complication. ConclusionSelection of treatment approaches according to the prognostic assessment of malignant trophoblastic neoplasia could lead to promising survival rate with no uncurable complication and toxic effects.

OBJECTIVETo evaluate the results of Gynatron low dose rate (LDR) brachytherapy for cancer of uterine cervix.

METHODSFrom April 1980 to June 1986, 136 patients with uterine cervical carcinoma were given radical radiotherapy through LDR afterloading irradiation and (60)Co external irradiation, compared with those through radium and high dose rate (HDR) intracavitary therapy.

RESULTSAll patients except 5 were followed up for 15 years with a follow-up rate of 96.3% (131/136). The overall 10-year survival rate was 63.5%. The 10-year survival rates of stage II and III patients were 83.9% and 43.2%. The frequency of proctitis and cystitis were 12.5% (17/136) and 9.6% (13/136).

CONCLUSIONGynatron LDR system has achieved good results with tolerable complications including proctitis and cystitis which are more often than those of radium and less so than those of HDR.

OBJECTIVETo evaluate the feasibility of surgical management for patients with locally advanced carcinomas of uterine cervix after radical radiation therapy who were prone to develop central recurrence.

METHODSThese 40 patients were treated by combined pre-operative radiotherapy with dose at point A of > 70 Gy in 30 patients, 60 approximately 70 Gy in 7, 50 approximately 59 Gy in 2 and 44 Gy in 1. The interval between radiation and surgery was 1 - 6 weeks. Extrafascial hysterectomy was performed in 15 patients, subradical hysterectomy in 23 and radical hysterectomy with pelvic lymphadenectomy in 2 cases.

RESULTSThese patients have been followed up for 1 - 8 years with 2 died of other diseases and 12 died of cancer. Eighteen of the 26 survivors have been followed up for more than 5 years. The 3- and 5-year survival rates were 74.9% and 66.8%. Half of the death occurred within the first year after treatment. The 2-year death rate was 9/12 (75.0%). Three patients suffered from long term complications after the treatment, but all were cured by conservative management.

CONCLUSIONThe combination of hysterectomy performed shortly after radical radiotherapy, ie, for patients with locally poor prognostic cervical carcinoma is reasonable and feasible.
