BACKGROUND: Pdor findings have demonstrated that body mass of Minority students aged 18-22 years old in Guangxi Zhuang Autonomous Region of China is slightly lower than concurrent nationwide level.OBJECTIVE: To further investigate the information with respect to healthy status including somatotype and body mass of 2 645 Minority students in Guangxi Zhuang Autonomous Region of China and to search for correlated influencing factors.DESIGN, TIME AND SETTING: A follow-up investigation was performed in the Guangxi University for Nationalities between December 2004 and December 2007.PARTICIPANTS: A total of 2 645 college students consisting of 1 337 males and 1 308 females who received health examination between years 2003 and 2005 in Guangxi University for Nationalities were recruited into this study. They were aged 18-20 years and were from 15 nationalities.METHODS: According to Health Standard of Students' Constitution (Tdal Program) formulated by the Ministry of Education of China and General Administration of Sport of China, examination indices included somatotype, skills, and physical constitution.Physical functions and body mass index (BMI) of 2 645 Minority students were followed up. MAIN OUTCOME MEASURES: Body height, body mass, vital capacity, bending forward while in a sitting position, standing long jump, and BMI.RESULTS: ①The mean increase rate of body height and body mass across 3 years for male college students in Grade 2003 in Guangxi University for Nationalities was 2.45% higher than the concurrent nationwide mean level, and somatotype development was in the peak phase; in addition, female students presented with a little thin body shape, demonstrating slightly poor somatotype development. ②When newly recruited into university, the vital capacity of male and female students was very poor,which was greatly lower than the concurrent nationwide level. Three years later, the vital capacity was increased by 11.55% and 27.72% for male and female students, respectively, both of which was higher than corresponding concurrent nationwide level.③ The function of bending forward while in a sitting position of male and female students was higher than the corresponding concurrent nationwide level. The function of bending forward while in a sitting position of male students tended to increase year by year, while the concurrent nationwide level of male students was gradually decreased, and the concurrent nationwide level of rural female students was gradually increased.④The function of standing long jump was greatly improved. The mean increase rate across 3 years was 18.15%, which was 2.61% higher than the concurrent nationwide level. The general standing long jump function of female students was poorer compared to the corresponding concurrent nationwide level. ⑤The general BMI of male and female Minority students was a little lower than the corresponding concurrent nationwide level (P< 0.01).CONCLUSION: All recruited 2 645 Minority students were in the peak of development, and the function of vital capacity was poorer compared to the concurrent nationwide level. BMI distribution was different in female and male students, and there were more female students presenting with lower body mass than male students, demonstrating a general poor nutritional state of college students.

Objective To obserVe the effect of gyPenoside on liPid Peroxidation and hePatic lesion in rats with tyPe 2 diabetes mellitus and nonalcohol fatty liVer disease. Methods Totally,65 SPF male SD rats were randomly diVided into blank control grouP (grouP N),NAFLD model grouP (grouP NM),and NAFLD with T2DM model grouP. The NAFLD with T2DM model grouP was further diVided into three subgrouPs:JH grouP,Perfused with 1 g·kg-1 ·d-1 GPS;JL grouP,Perfused with 0. 5 g·kg-1 ·d-1 GPS;model control grouP,Perfused with the same Volume of water.

TG, malondialdehyde (MDA),and suPeroxide dismutase (SOD) in the liVer tissue were also tested. Results ADP leVel was (7. 46±1. 12),(3. 58±0. 98),(4. 89±1. 02),(4. 79±1. 01) and (4. 13±0. 89) ng·mL-1 in N,M,NM,JH and JL grouPs, resPectiVely. The ADP leVel was significantly higher in grouP JH and JL than in grouP M (P<0. 01),and significantly higher in grouP JH than in grouP JL (P<0. 05). MDA leVel was (2. 98±0. 09),(4. 22±0. 11),(3. 66±0. 10),(3. 72±0. 11),(3. 99±0. 13) nmol·mL_1 in N,M,NM,JH and JL grouPs,resPectiVely. The MDA leVel was significantly lower in grouP JH and JL than in grouP M (P<0. 01),and significantly lower in grouP JH than in grouP JL (P<0. 05). SOD leVel was (240. 8±17. 4), (149. 9±20. 6),(181. 6±19. 4),(209. 8±19. 2),(189. 4±18. 9) U·mL_1 in N,M,NM,JH,and JL grouPs,resPectiVely. SOD leVel was significantly higher in grouP JH and JL than in grouP M (P<0. 01),and significantly higher in grouP JH than in grouP JL (P<0. 05). TG leVel was (28. 98±1. 68),(214. 46±5. 44),(198. 46±6. 98),(142. 87±6. 64) and (164. 92±7. 56) mg·g-1 in N,M,NM,JH and JL grouPs,resPectiVely. TG leVel was significantly lower in grouP JH and JL than in grouP M ( P<0. 01),and significantly lower in grouP JH than in grouP JL (P<0. 05). ALT and AST were significantly lower in grouP JH and JL than in grouP M (P<0. 01),and significantly lower in grouP JH than in grouP JL (P<0. 05). Conclusion The liPid Peroxidation in the liVer of rats with T2DM comPlicated with NAFLD can be reduced by gyPenoside,and hePatic lesion may be alleViated through inhibition of liPid Peroxidation.

Objective Primitive neuroectodermal tumor ( PNET) is a small round cell tumor occurring mostly in children or young adults and categorized into the Ewing sarcoma family of tumors, the purpose of the study was to investigate the clinical features, treatment and prognosis of Children PNET. Methods A retrospective study was performed on clinical data of 13 children with PNET hospitalized in our hospital from March 2010 to Octorber 2014.In order to analyze the clinical effects and prognostic results, statistical analysis was made on their clinical manifestations, CT and ultrasonic results, therapeutic schemes, postoperative pathology and immu-nohistochemical staining results, along with telephone and outpaitient follow-up of average 19 months. Results Of the 13 patients, 4 cases were central nervous system PNET(CNS-PNET) and 9 cases were peripheral PNET(pPNET).The clinical manifestations of the former were headache, vomiting, convolsion, movement disorder or decreased muscle strength, while the latter mainly showed mas-ses and abdominal distention.3 cases with metastasis to lung, lymph nodes and bones respectively showed masses on surface or in cavi-ty in imaging.Homer-Wright pseudorosette textures were found in 12 patients.Immunohistochemical results showed 11 cases with CD99(+), 9 cases with VIM(+) and 8 cases Syn( +).Among 11 patients underwent chemotherapy, 2 cases were lost to follow-up, 7 cases were in stable condition without occurrence and the other 2 cases recurred 4-6 months after chemotherapy.3 of 4 cases with CNS-PNET survived with the sequelae of decreased muscle strength, convolsion and movement disorder.1 case with CNS-PNET and 1 case with pPNET died 7 months and 16 months after diagnosis respectively. Conclusion PNET in children is a very highly malignant tumor with low long-term survival rate.Immunohistochemi-cal examination including CD99 and VIM is of important diagnostic value and CNS-PNET is prone to sequelae.

OBJECTIVE:To observe the effect of ulinastatin on the serum inflammatory cytokines of patients with ulcerative colitis. METHODS:Totally 60 patients with ulcerative colitis were randomly divided into observation group and test group,and an-other 20 healthy volunteers were selected as normal control group. Test group were received routine treatment,including nutrition support and maintaining water,electrolyte balance and 5-amino salicylic acid (5-ASA),etc. Patients in observation group were treated by ulinastatin 200 000 U by intravenous infusion based on the treatment of test group,q12h. 7 d were as a course for the pa-tients,and it lasted for 2 courses. The clinical data in healthy control group and other 2 groups was observed,including tumor ne-crosis factor-α(TNF-α),interleukin-1β(IL-1β),IL-8,C-reactive protein(CRP)levels,colon peroxidase activity(MPO),clinical activity index(CAI)scores and the incidence of adverse reactions before and after treatment. RESULTS:Before and after treatment, the TNF-α,IL-1β,IL-8,CRP and MPO in other 2 groups were significantly higher than health control group,with significant dif-ferences(P<0.05). After treatment,the TNF-α and IL-1β in 2 groups and the IL-8 and CRP levels in observation group were low than before,and the TNF-α,IL-8 and CRP levels in observation group were significantly lower than test group,with significant dif-ferences(P<0.05). There were no obvious adverse reactions during treatment. CONCLUSIONS:Based on the routine treatment, ulinastatin can effectively inhibit the expression of inflammatory cytokines of patients with ulcerative colitis,and relieve the inflam-mation and injury of colon,with good safety.

MicroRNAs(miRNAs) are a class of highly conserved,endogenous,small,non-coding RNAs that reg-ulate RNAi and are key regulators of tumorigenesis and development.miR-338 is abnormally expressed in most tumors. Aberrant expression of miR-338 can affect the proliferation, invasion, metastasis, angiogenesis and other physiological activities of tumor cells and play a vital role in the regulation on one or more target-genes.
