BACKGROUND:Thyroid cancer stem cells are one of the reasons for tumor resistance that promotes tumor development. The research of thyroid cancer stem cells has provides a new clinic means for the diagnosis and treatment of thyroid cancer. OBJECTIVE:To overview the discovery, identification, and correlation of thyroid cancer stem cells with thyroid cancer. METHODS:A computer-based online search of PubMed database and Wan Fang database between 1995-01/2014-01 was performed to search related articles with the key words of“thyroid cancer, cancer stem cell, stem cell, cancer suppressor gene”in English and Chinese, respectively. Literatures related to thyroid cancer stem cells were selected;in the same field, the articles published lately in authoritative journals were preferred. RESULTS AND CONCLUSION:A total of 561 literatures were primarily selected, and 57 documents were involved for result analysis according to inclusion criteria. Cancer stem cells have become a focus in the study of carcinogenesis. Stem cells also exist in the thyroid gland and its tumor. At present, there are several ways to isolate and identify thyroid cancer stem cells. The tumor thyroid stem cells are closely related to the occurrence, transfer and treatment of tumors. But whether we can cure thyroid cancer through restraining or eliminating thyroid cancer stem cells is stil unknown that needs further studies.

Objective To observe the clinical efficacy of self made Qinchai Kangdu mixture for treatment of infantile EB virus (EBV) infectious mononucleosis and explore its potential mechanism. Methods A prospective study was conducted. One hundred and twenty children with pediatric EBV infectious mononucleosis and traditional Chinese medicine (TCM) syndrome of flaring heat in Qifen and Yingfen in Wuhan Children Hospital were randomly divided into observation group and control group (each, 60 cases). Conventional western medical treatment was given to the two groups for 7-10 days;the observation group was additionally given Qinchai Kangdu mixture which included the following ingredients:Scutellariae Radix 10 g, Bupleuri Radix 10 g, Artemisiae Annuae Herba 10 g, Forsythiae Fructus 20 g, Arctii Fructus 10 g, Paeoniae Radix Rubra 10 g, Cinnamomi Ramulus 6 g, Moutan Cortex 10 g, Trionycis Carapax 10 g, Isatidis Radix 20 g, Citri Reticulatae Pericarpium 10 g, Glycyrrhizae Radix 10 g, orally, once daily for 7-10 days. The times of returning to normal for clinical symptoms and signs, white blood cell count (WBC), peripheral blood abnormal lymphocyte ratio and the level of alanine aminotransferase (ALT) were observed in the two groups. And the clinical efficacy, changes in score of TCM syndrome and adverse reactions were also investigated in the two groups. Results The total effective rate in the observation group was significantly higher than that in the control group [93.33%(56/60) vs. 76.67%(46/60), P<0.05]. In observation group, the duration of fever (days:6.9±2.3 vs. 7.7±3.4), and the recovery times to normal for body temperature (days:2.9±1.4 vs. 4.8±1.7), angina (days:7.2±3.3 vs. 8.0±3.2), lymph node reduction in size (days: 6.6±2.1 vs. 10.2±2.0), enlarged liver bounce back in size (days: 7.8±1.7 vs. 9.6±2.0), WBC (days:7.22±1.78 vs. 10.67±1.97), peripheral blood abnormal lymphocyte ratio (days:7.24±1.86 vs. 11.15±1.65), and ALT (days:8.44±1.83 vs. 11.43±2.65) were all significantly shorter than those in the control group (all P < 0.05). No adverse reactions occurred in the therapeutic course in the two groups. Conclusions Qinchai Kangdu mixture can effectively improve the clinical symptoms of infantile EBV infectious mononucleosis with TCM syndrome of flaring heat in Qifen and Yingfen. The mixture may also promote the enlarged liver and spleen to contract in size at early stage and peripheral blood abnormal lymphocyte ratio and other laboratory indexes return to normal in time.

Objective:To observe the efficacy of acupuncture at points of Shaoyang meridians plus moving cupping on neck and shoulder for migraine. Methods:A total of 64 migraine cases were randomly allocated into an observation group and a control group, 32 cases in each group. Random number table method was used in allocation. Acupuncture at points of Shaoyang meridians and cupping on neck and shoulder were used for cases in the observation group, which contain acupuncture 5 times a week and cupping once a week. Oral flunarizine hydrochloride capsules were used for cases in the control group, 10 mg for each dose, 1 dose a day. 2 weeks constitutes a course of treatment. The patients were treated for two courses of treatment in both groups. After that, the changes of visual analogue scale (VAS) and the migraine disability assessment questionnaire (MIDAS) were observed, as well as the clinical efficacy. Results:The total effective rate and recovery and marked effective rate in the observation group were 93.8% and 71.0% respectively, versus 78.1% and 43.8% in the control group, showing statistical significant differences (both P<0.05). There were significant decreases in VAS and MIDAS scores after treatments in both groups (both P<0.05). VAS and MIDAS scores in the observation group were significantly different from those in the control group (both P<0.05). Conclusion: Combining acupuncture at points of Shaoyang meridians and cupping on neck and shoulder can relieve headache and reduce influence of migraine on life. It can produce a better efficacy than oral flunarizine hydrochloride capsules in treating migraine patients.

Objective To compare the efficacy of liposuction and open surgery for patients with accessory breast.MethodsA total of 73 patients with accessory breast,who were treated in our hospital from June 2000 to December 2007,were enrolled in this study and divided into open surgery(June 2000 to June 2004,43 patients with accessory breast at 80 sides)and liposuction(April 2004 to December 2007,30 cases with accessory breast at 58 sides)groups.The outcomes of the patients,operation time,and intraoperative blood loss in the two groups were compared.Results The curative rate of the both groups were 100%.However,the open surgery group had more blood loss [(49.6?13.3)ml vs(28.9?6.9)ml,t=10.836,P=0.000] and longer operation time[(57.4?11.1)min vs(27.3?4.3)min,t=19.597,P=0.000].Conclusions Compared with open surgery,liposuction leads to quicker recovery and less trauma without leaving scars,and thus is more acceptable to the patients.

The ecological balance of intestinal microbiota plays an important role in digestion,absorp-tion,metabolism,immunity and protection against pathogens.Intestinal microbiota can not only regulate the innate immunity of the body,but also can stimulate the immune response by the bacteria itself and its metabo-lites.The imbalance intestinal microbiota may lead to abnormal immune mechanism,and then participate in the occurrence and development of the tumor,especially colorectal cancer.

Objective To explore the prognostic role of nutritional benefit assessment (NUTRIC score), nutritional risk screening 2002 (NRS 2002), traditional nutritional laboratory indicators albumin (ALB) and prealbumin (PA) in critically ill patients. Methods A historical-prospective cohort study was conducted. The data of 427 patients admitted to Department of Critical Care Medicine of the Affiliated Hospital of Guizhou Medical University from February 2014 to October 2014 were retrospectively analyzed, and thereafter a follow-up of 275 critically ill patients from November 2014 to April 2015 prospectively enrolled was performed. 261 patients were enrolled finally. Patients were divided into death group and survival group according to 28-day and 90-day outcome, the baseline data, acute physiology and chronic health evaluationⅡ (APACHE Ⅱ) score, sequential organ failure assessment (SOFA) score, NRS 2002, NUTRIC score, ALB and PA were compared between the two groups. Logistic regression analysis was used to find risk factors for 28-day and 90-day prognosis. Results ① NRS 2002 score of all the 261 patients were greater than or equal to 3 with 100% nutritional risk. The patients in NUTRIC score 5-9 group had lower ALB and PA, higher NRS 2002 score, longer mechanical ventilation time and length of intensive care unit (ICU) stay, which indicated they were more serious. ② Twenty eight-day mortality was 20.7% (54 died from 261). Compared with survival group, the patients in death group had higher APACHE Ⅱ, SOFA, and NUTRIC scores [29.00 (22.75, 34.25) vs. 24.00 (20.00, 28.00), 10.0 (8.0, 13.0) vs. 9.0 (7.0, 11.0), 6.37±1.84 vs. 5.59±1.64, all P < 0.01], and longer days from hospital to ICU admission and mechanical ventilation time in ICU [1.5 (0, 9.2) days vs. 0 (0, 4.0) days, 6.0 (4.0, 11.0) days vs. 4.2 (2.5, 7.8) days, both P < 0.05]. It was revealed by logistic regression analysis that APACHE Ⅱ score [odds ratio (OR) = 1.089, 95% confidence interval (95%CI) = 1.039-1.141, P = 0.000] and days from hospital to ICU admission (OR = 1.042, 95%CI = 1.014-1.071, P = 0.003) were the independent risk factors for 28-day death in critically ill patients. ③ Ninety-day mortality was 42.5% (111 died from 261). Compared with the survival group, the death group patients were older with higher APACHE Ⅱ, SOFA, NRS 2002, and NUTRIC scores [age (years): 64.44±18.11 vs. 54.25±19.66, APACHE Ⅱ: 27.00 (23.00, 31.00) vs. 23.00 (20.00, 27.00), SOFA: 10.0 (8.0, 12.0) vs. 9.0 (7.0, 11.0), NRS 2002: 5.08±1.47 vs. 4.67±1.41, NUTRIC: 6.32±1.58 vs. 5.33±1.68], ALB was significantly reduced [g/L: 27.70 (23.05, 32.00) vs. 30.73 (26.90, 34.20)], and mechanical ventilation time in ICU was extended obviously [days: 5.7 (3.6, 11.0) vs. 3.9 (2.4, 7.0), all P < 0.05]. It was revealed by logistic regression analysis that old age (OR = 1.019, 95%CI = 1.002-1.037, P = 0.029) and NUTRIC score (OR = 1.211, 95%CI = 0.983-1.491, P = 0.072) were the independent risk factors for 90-day death probability, and ALB probability was the protect factor for 90-day death (OR = 0.954, 95%CI = 0.916-0.994, P = 0.024). Conclusion It was NUTRIC score but not NRS 2002, ALB and PA predicted 90-day mortality in critically ill patients.
