Purpose:To investigate the rational choice of adjuvant treatment and its clinical value for stage Ⅰb, Ⅱa cervical cancinoma after radical hysterectomy and pelvic lymphadenectomy.Methods:126 patients with stage Ⅰb and Ⅱa cervical cancer received adjuvant radiotherapy and/or chemotherapy after radical hysterectomy and pelvic lymphadenectomy .Of these patients, 64 received radiotherapy only, 26 chemotherapy only, 36 had both. The prognostic factors and treatment results were analyzed.Results:The overall 5-year survival rate for the 126 patients was 73%(92/126). For the radiotherapy only, chemotherapy only, and the radio-chemotherapy groups, the 5-year survival rates were 76.6%(49/64), 69.2%(18/26), and 69.4%(25/36) respectively. The clinical stages and the number of pelvic lymphnodes metastases were the most important prognostic factors. Conclusions:The value of adjuvant treatment for early stage cervical cancer after radical surgery was limited, but for patients who had more than two high risk factors, adjuvant treatment should be given, and at the same time, we should emphasis the importance of thoroughness of radical hysterectomy and pelvic lymphadenectomy.

Objective To prepare 60 mer oligo microarray chips for detecting human immunodeficiency virus (HIV) and for the clinical application in the detection of AIDS patient. Methods Oligonucleotide probes were designed according to the sequence information of two types of HIV. Oligo microarray was prepared by using Cartesian Microarrayer. Products of the restrictive display PCR were labeled with Cy3. Furthermore, the PCR products were sequenced. Results Using the oligo microarray, HIV infection could be detected in laboratory as well as in clinical assays. Results of hybridization indicated that 1 AIDS patient was positive and 20 health people were negative. The results obtained by sequencing confirmed the results obtained by oligo microarray studies. Conclusion The HIV 60 mer oligo microarray could be used in detecting patient HIV infection and analyzing its genotypes.

It is necessary to determine the position of break points in order to study the structure rearrangement of chromosomes and gene mapping. Therefore it is indispensable to set up region, banded idiogram and nomenclature system. Nesbitt and Franke reported an idiogram and a nomenclature system for band patterns of mouse chromosomes which thereafter was accepted by the Committee on Standardized Genetic Nomenclture. Nevertheless, there are few data of systematical contrast studies in this domain. There are still difficulties for distinguishing between some chromosomes because they are similar and variability. In this paper, we compared our G-banding karyotypes with the banding patterns of Nesbitt's idiogram. Our 400 karyotypes come from bone marrow cells and fibroblasts of several normal inbred and outbred mice. Each banding obtained from each well banded chromosomes of different cells were contrasted to that of Nesbitt's idiogram. The results are as follows: 1. we have not found so many bands in one metaphase chromosome banded with trypsin-Giemsa technique as reported by Nesbitt. 2. The banding numbers and positions on each well banding chromosome picked out from different metaphase plates were consistent with those of Nesbitt's idiogrom. But some bands such as 1E1 and 1E2; 2E5-2F5; 4A3-4A5; 5C1-5C3 can't usually be distinguished in our data. 3. We observed that the major banding structure of each karyotype remains stability, but the minor banding structure appears to be variablitity in inbred mice. In addition, 6 variant pictures and region idiograms in the G-banding structure of each chromosome were showed and some notices for correct analysis of mouse karyotype were discussed.

Objective To investigate the effects and the possible mechanisms of nerve growth factor (NGF) on serum levels of vascular endothelial growth factor (VEGF) and stromal cell-derived factor 1 (SDF-1) protein expression in rats with focal cerebral ischemia.Methods Male Sprague-Dawley rats weighting 200 ～ 250 g were subjected to middle cerebral occlusion (MCAO).MCAO rats were randomly divided into NGF group,saline control group and NGF+PI3K antagonist group (n =12).The neurological function was evaluated on the 4th,7th day after MCAO,and the serum levels of VEGF and SDF-1 protein were measured by ELISA.Results The neurological function was better in rats of the NGF group than those of the saline control group and NGF+PI3K antagonist on the 4th,7th day after MCAO (P ＜ 0.05).The serum levels of VEGF and SDF-1 protein of the NGF group was significantly higher than that of the saline control group and NGF+PI3K antagonist group on the 4th day after MCAO (P ＜ 0.05).Conclusions Treatment with NGF may improve neurological function of rats with focal cerebral ischemia,and upregulate serum levels of VEGF and SDF-1 protein expression.PI3K/AKT signal pathway may have attended the above regulation.

Objective To present the status of smoking control in the Health and Family Planning System in Hubei Province, and to provide scientific basis for smoking control through secret investigations. Methods During the period from July to August in 2015, 168 sanitary Health and Family Planning institutions were chosen by stratified selection to make questionnaires based on Evaluation Standards for Smoke-free Health and Family Planning Institutions issued by the National Health and Family Planning Commission of the People's Republic of China. Secret investigations were conducted in 165 sampled institutions and comparisons were made between smoke-free environment establishment as well as execution processes according to the fraction after converting into centesimal system (actual score/reserved portion × 100). Results The overall score for smoking control in Health and Family Planning System of Hubei Province has climbed to 79.29 ± 12.40.compared to that of 2011 has increased, but 1.6 lower than the national comprehensive evaluated score of 2014. The score of the city (82.14 ± 10.51) proved to be higher than that of the province (66.51±19.69) and the county, (75.35±13.40);disease control institutions (84.77± 9.45) enjoyed a higher score that the others with lowest scores in medical institutions (72.80 ± 14.95);Xianning won the highest score (88.52±5.12);Jingmen (69.81±5.16) and Xiaogan (67.92±7.98) proved to be the lowest in their scores. Nine regions in 17 embraced a lowest discrepancy of over 30 scores and the highest discrepancy of 50.94 scores between the highest score and the lowest among different institutions;12.73% (21/165) medical institutions had no publicity materials; 5/17 municipal institutions and 3/10 county level institutions were still found selling cigarettes, with only 46.06%(76/165) institutions reaching the standard of banning smoking in indoor places, 21.21%(35/165) institutions still have indoor smoking in non-working places, 1.82%(3/165) institutions have indoor smoking in working places. Only 18 (32.14%) institutions out of 56 medical institutions investigated have established smoking cessation clinics. Conclusions Banning-smoking work is less optimistic in general for Health and Family Planning System in Hubei Province, especially for substratum health and family planning institutions. All kinds of departments should take drastic measures to guaranttee the establishment of smoking-free environment.

Objective To investigate the effects of ketogenic amino acid ( KAA) replacement diet on insulin resistance in mice fed with high fat diet(HFD) and to analyze the possible mechanism. Methods C57BL mice were fed with a control diet, HFD, and KAA-fortified HFD(HFDKAAR)from the age of 8 weeks, and 8 weeks after HFD initiation, the HFD-fed mice were divided into two groups:one group of mice were fed the same HFD, the other group were fed HFDKAAR ( HFD→HFDKAAR ) . The metabolic evaluations were performed at the end of 16 weeks. Blood glucose levels were measured at 0, 15, 30, 60, 90, and 120 min after the injection of glucose ( 1 g/kg BW intraperitoneal glucose tolerance test, ipGTT) . The insulin,β-hydroxybutyrate, and acetoacetate levels in the plasma were measured via ELISA. The insulin resistance index ( IRI) and area under curve ( AUC) were calculated. The expression of hepatic LKB1 ( liver kinase B1 ) , AMP-activated protein kinase ( AMPK ) , and mTOR ( Mammalian target of rapamycin ) protein, and mcp-1 mRNA were measured by western blot and real-time PCR respectively. Results HFD-fed group of mice displayed significantly heavier body weight,heavier intra-abdominal fat weight, and significant deterioration of glucose tolerance at the end of 16 weeks in addition to higher insulin levels( all P<0. 05), HFDKAAR-fed mice exhibited significantly ameliorated high fat diet-induced obesity and glucose intolerance compared to the HFD-fed mice, which was associated with decreased insulin levels, IRI, AUC, and mcp-1 mRNA expression (all P<0. 05). HFD suppressed hepatic LKB1 and AMPK phosphorylation expression, and increased mTOR phosphorylation levels compared to the control diet-fed mice(all P<0. 05). In contrast, treatment with the HFDKAAR diet increased LKB1and p-AMPK expression, which was associated with suppressed p-mTOR levels compared to the HFD-fed mice(all P<0. 05). Conclusion KAA may ameliorate high fat diet-induced obesity, glucose intolerance, via normalizing the hepatic LKB1-AMPK-mTOR nutritional signal passageway. KAA replacement diet seems to be a potential nutritional intervention for the treatment for patients with metabolic defects, such as obesity, glucose intolerance, as well as metabolic syndrome.

Objective To calculate the incidence of pathology-proved bilateral well-differentiated thyroid carcinoma (BWDTC) in patients undergoing total or near total thyroidectomy.Methods Clinical data were retrospectively reviewed in 121 patients who underwent total or near total thyroidectomy.Thirteen indexes selected from both the unilateral thyroid carcinoma group and the bilateral thyroid carcinoma group were adopted to undergo a univariate analysis and Logistic regression analysis.Results BWDTC was found in 33.06％ patients after total or near total thyroidectomy.Logistic regression analysis showed that patient's age ＜ 50,bilateral nodules based on ultrasound and the diameter of the tirst nodule ＞ 2 cm were independent risk factors for BWDTC (P ＜ 0.05).Conclusions In the premise of a malignant first nodule found in the preoperative examinations,BWDTC should be highly suspected if the patient is under 50 years old,has bilateral nodules found by preoperative ultrasound and the diameter of the first malignant nodule is over 2 cm.

Objective To observe the changing levels of serum sFas before and after intravenous i mmunoglobulin (IVIG) treatment of incomplete Kawasaki disease (IKD),to explore the roles of sFas in the pathogenesis of IKD and IVIG treatment mechanism.Methods Thirty eight cases of IKD children were selected as experimental group and 20 examples of the same age of children as the control group.The IKD children were treated by IVIG in combination with aspirin (ASP) ; and blood test was performed before treatment,3 days after treatment,and 14 days after treatment,respectively.Dual-resistant sandwich enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of serum sFas,plasma Fibrinogen (PT-D),d-dimer (D-D),and c-reactive protein (CRP).Results The levels of serum sFas,PT-D,D-D,and CRP were significantly higher than the control group for IKD children before treatment[(0.55 ± 0.14)ng/L vs (0.24 ±0.04) ng/L,(552.3 ± 147.2) mg/dl vs (277.3 ±82.5)mg/dl,(649.0 ±201.6) μg/L vs (315.4 ±91.8)μg/L,and(72.2 ±28.7)mg/L vs (7.2 ±2.9)mg/L; t' =12.41,9.11,8.64,13.82;All P ＜ 0.05] ;3 days after treatment,compared with those before treatment and control group,the sFas level of IKD children at the third day after treatment was significantly decreased compared to that before treatment and control groups,respectively [(0.43 ± 0.09) ng/L vs (0.55 ± 0.14) ng/L,(0.24 ± 0.04) ng/L,F =47.624,All P ＜0.05] ;For the level of sFas at the 14th day after treatment,no statistical significance was found between IKD children and the control group[(0.24 ±0.05) ng/L vs (0.24 ±0.04) ng/L,t =0.596,P ＞ 0.05].Conclusions The abnormally increased serum sFas level before IVIG treatment suggests that dysfunction of apoptosis be involved in the pathogenesis of the IKD.Intravenous immunoglobulin treatment may be involved in the apoptosis process.

Objectives To explore the change of interleukin-17 (IL-17) in Kawasaki disease (KD). Methods Fourty KD pediatric patients, among them 12 patients with echocardiographic abnormalities in acute phase, 25 age-matched non-KD patients were enrolled. The level of serum IL-17 was measured by enzyme linked immunosorbent assay in acute and convalescent phase of KD patients and non-KD patients. At the same time, C-reactive protein (CRP), globulin, albumin were detected. Results In acute phase of KD patients, the level of serum IL-17 were signiifcantly higher than that in convalescent phase of KD patients and non-KD patients (P<0.05). The level of serum IL-17 was no signiifcant differences in convalescent phase of KD patients and non-KD patients (P>0.05). In acute phase of KD patients with echocardiography abnormalities, the level of serum IL-17 was signiifcantly higher than that with non-echocardiography abnormalities (P<0.05). The level of serum IL-17 in acute phase of KD patients were positively correlated with CRP and globulin (r=0.750, 0.750, P<0.05), and negatively correlated with albumin (r=-0.779, P<0.05). Conclusions IL-17 may be involved in KD immune pathogenesis. Serum IL-17 is one of the activity index of KD, which associ-ated with cardiovascular damages.
