There are 13 members of the Let -7 miRNAs family which is regarded as tumor suppressor gene, locating in nine different chromosome loci. Lin28 acts as negative regulatory factor of miRNA biological recurrence. By selectively blocking the processing synthesis of the Let-7 miRNAs family, Lin28 block the inhibition effect of miRNA of proto-oncogenes and interact with RNA helicase to enhance gene translation at the same time. By not quite clear mechanism, an up-regulation of Let-7 inhibits the expression and function of Lin28. In more and more studies of human tumor, Lin28/Let-7 axsis was proved to be important significance of the tumor's occurrence and development. In this paper, we research briefly the recent progress of the molecular mechanism and related influence factors of ILin28/Let-7 axsis.

AIM: To test the effects of FTY720 on mouse intestinal allografts.METHODS: C_3H mice(H-2~k)were used as donor and C57BL/6 mice(H-2~b) as recipients.FTY720 group,allogeneic control group and isogeneic control group were set up.6 and 14 days after transplantation,murine intestinal grafts were harvested for histologic assessment.Lymphocytes were collected from mesenteric lymph nodes(MLN),Peyer's patch(PP),lamina propria lymphocytes(LPL) and intraepithelial lymphocytes(IEL) in the graft,then were analyzed by cytometry.RESULTS: Rejection was inhibited in FTY720 group at the 6th post-transplant day,although not at the 14th day.Recipient CD4~+ and CD8~+ T cells,CD19~+ B cells,as well as ?? TCR lymphocytes,were greatly reduced by FTY720 therapy.The similar action of FTY720 was also revealed in Gr1~+CD11b~+ monocytes.CONCLUSION: FTY720 is efficient on alleviating allo-immune response by reducing the infiltration of both lymphocytes and monocytes into the graft in a mouse intestinal transplantation model.

ObjectiveUsing large sample clinical study to reevaluate the safety and efficacy of recombinant human growth hormone(ANSOMONE) in treating pediatric growth hormone deficiency(GHD).Methods1012 cases were administered with ANSOMONE at a dose of 0.1 IU · kg-1 · d -1 in bedtime for 6 months.The alteration of mean height,growth rate,height standard deviation scores,bone age,and anti-GH antibody and occurrence of adverse effects were observed.ResultsThe growth rate was promoted from ( 2.50 ± 0.85 ) cm/year to ( 13.44 ± 4.27 ) cm/year,the net growth rate was( 10.94 ±3.69)cm/year.There was significant difference between the pre-treatment and post-treatment patients ( P ＜ 0.01 ).The post-treatment anti-GH antibody positive rate was 13.34％,which had no obvious effect on the efficacy.Few patients exert transient inflammation reactions,which disappeared with any treatment.ConclusionANSOMONE had significant efficacy,and could promote the height increase obviously.It had good safety without any obvious side effect and early-maturing effect.

Objective To investigate the relationship between isolated nocturnal hypertension and left ventricular hypertrophy. Methods In the inhabitants of 14 villages in Jingning County, Zhejiang Province, we performed 24-hour ambulatory blood pressure monitoring with SpaceLab monitors and measured 12-lead resting electrocardiogram using an electronic recording system of GE company, Left ventrieular hypertrophy was diagnosed with the criteria of Sokolow-Lyon voltage amplitude and Cornell product. Isolated nocturnal hypertension was defined as a nighttime ( from 22:00 to 4:00) blood pressure of ≥ 120/70 mm Hg( 1 mm Hg = 0. 133 kPa). Isolated daytime ( from 8:00 to 18:00) hypertension was a diurnal blood pressure of ≥ 135/85 nun Hg. When both conditions were present or absent, subjects were classified either as having combined day-night hypertension or as normotensive on ambulatory measurement. Analysis of variance and multiple regressions were used for statistical analysis. Results 647 participants (53.9% being female,average age 47. 8 years) included 72 patients with isolated nocturnal hypertension, 33 with isolated daytime hypertension and 248 with day-night sustained hypertension. Compared with normotensive subjects, patients with isolated nocturnal hypertension and day-night sustained hypertension had a higher Sokoiow-Lyon voltage amplitude and Comell product. However, after adjustment for sex, age, body mass index, drinking and smoking habits, serum total cholesterol, fasting blood glucose and the use of antihypertensive drugs, only day-night hypertensive patients had a significantly higher Sokolow-Lyon voltage (32. 8 mV, P =0. 0003 ) and Cornell product (1371 mV×ms, P =0.0004) than normotensive subjects (29.0 mV, 1114 mV×ms).Regardless of whether Sokolow-Lyon or Cornell criteria were used, both nighttime and daytime systolic and diastolic blood pressure were independent risk factors of left ventricular hypertrophy (P < 0. 01 ). However,the prevalence of left ventricular hypertrophy in patients with isolated nocturnal hypertension ( 23.6% ) study was not statistically different from that in normotensives ( 17.4%, P = 0. 24). Conclusion In our current cross-sectional study, isolated nocturnal hypertension was not independently related to left ventricular hypertrophy diagnosed with ECG criteria.

There are actually no sufficient data for lifting technique assessment. A laboratory study was undertaken to determine the effect of 3 regular lifting techniques on erector muscle activation, cardiovascular strain and subjective response. Thirty student volunteers participated in the study, and were required to lift a weight with different techniques. Stoop-, squat-, semi-squat-lifting resulted in 3, 2 and 1 time of the highest percentage of the maximum voluntary electrical activation (MVE%) respectively. In the same order, the lowest median frequency (MF) existed 1, 1 and 2 times. Muscle fatigue was 4 times in squat, 36 in semi-squat and 43 in stoop lifting. Heart rate was the highest in squat and lowest in stoop respectively, with a middle level in semi-squat lifting. It may be recommended to adopt mainly the semi-squat technique for daily lifting works. For heavy lifting, it should use the squat technique. Stoop lifting may also be used alternatively but for light things.

The overall satisfaction of the students was more than 97%, and 99% participants said that the training helped them enhance their confidence in clinical treatment, and 98% participants said that the training should be promoted among medical staff.Conclusion:The course of "oriental airway simulation training" which is made up of the combination of airway technical training, correct clinical decision-making and reality simulation, has significantly improved the airway management skills, enhanced the self-confidence of low-seniority medical staffs and improved patients' safety.

Objective To analyze the correlation between ≥grade 2 radiation pneumonitis (RP) and dose volume parameters of elderly patients with esophageal cancer after three-dimensional conformal radiotherapy. Methods We collected the data of 250 elderly patients with esophageal cancer who received three-dimensional conformal radiotherapy from different medical centers. The clinical features of patients were analyzed by Chi-square test while dose volume parameters were analyzed by Logistic univariate and multivariate analyses. ROC curve was used to determine the best cut-off value. Results After three-dimensional conformal radiotherapy, 20% of patients developed ≥grade 2 RP. Univariate analysis showed that bilateral pulmonary V5, V10, V20, V30 and mean lung dose were associated with ≥grade 2 RP but multivariate analysis revealed that only V5 and V20 were independent relevant factors of RP. ROC curve indicated that the best cut-off value was V5 < 52.9% and V20 < 23.2%. Conclusion Bilateral pulmonary V5 and V20 are independently related to ≥grade 2 RP in elderly patients with esophageal cancer after 3-D conformal radiotherapy.

Objective To compare the analgesic effect ofHuamoyan Keli(HMYKL) between Kunming mice and BALB/c mice.Methods Eighty Kunming mice and eighty BALB/c mice were randomly divided into five groups, respectively: a control group, a ibuprofen group, a HMYKL high-dose group(13.98 g crude dru g/kg), HMYKL middle-dose group(6.99 g crude drug/kg)and a HMYKL low-dose group(3.50 g crude dru g/kg). There were 16 mice in each group with 8 male mice and 8 female mice. Drugs were administered intragastrically daily for 5 days. After 1 h of drug treatment on day 4, the latency of tail-flick response was evaluated using illuminated pain measurement instrument. After the last drug treatment, pain model was established by i.p. acetic acid, writhing latency and writhing times were recorded to evaluate the analgesic effect of HMYKL.Results In tail-flick test, there was no statistical difference among male and female Kunming mice in the HMYKL groups. Among male BALB/c mice, the latency in HMYKL middle-dose group was significantly longer than that in the control group(4.84±1.16 minvs. 3.93±0.76 min,P<0.05). In writhing test, compared with control group(19.06±6.34), the writhing times among BALB/c mice were decreased in HMYKL high-dose group(8.56±6.19), HMYKL middle-dose group(5.73±3.17), HMYKL low-dose group(6.88±4.59)(allP<0.01).Conclusion All dose groups of HMYKL showed good analgesic effect on the pain induced by chemical stimulation and there was no sex difference. Kunming mice were not suitable for the evaluation of the analgesic pharmacodynamics because of their large individual difference. On contrast, BALB/c mice which had less individual difference could be used to produce the model of pain.

OBJECTIVETo investigate injury to epidermal melanocyte by Q-switched Alexandrite laser.

METHODSMultiple biopsies were performed on 5 patients with nevus of Ota from before irradiation to 1 year after irradiation. Fourteen specimens were obtained for light microscopy, and 17 for transmission electron microscopy.

RESULTSMelanosomes in epidermal melanocytes were both smaller in size and fewer in number than those in dermal melanocytes. Immediately after irradiation, focal extracellular vacuoles of the basal layer could be observed under light microscopy. Most epidermal melanocytes underwent mild or moderate injury in the form of vacuolated melanosomes, swollen mitochondria, dilation of endoplasmic reticulum, and expansion of extracellular space, retaining intact cell membranes. Normal structures were restored 5 months to 1 year after irradiation, with no depigmentation or hyperpigmentation as seen by light microscopy.

CONCLUSIONInjury of melanosomes in epidermal melanocytes is reversible.
