Objective To analyze the incidence and risk factors for regional nodal failure(RNF) and chest wall recurrence(CWR) in T1 or T2 breast cancer patients(median age 44 year-range 26-72) with 1-3 positive axillary nodes treated with postmastectomy radiotherapy limited to the regional nodes.Methods From 1990 to 1999,320 patients were treated with postmastectomy(radical or modified radical) radiother- apy confined to the supraclavicular and internal mammary nodes with a median dose of 50 Gy in 25 fractions over 5 weeks.The median number of nodes examined was 8 (range 1-24).The median lymph nods rate (LNR) was 25% (range 5%-100%).Results The 5-year overall survival rate and disease free survival rate was 89.7% and 83.4%,respectively.The 5-year RNF and CWR was 7.9% and 5.7%,respectively. The 5-year RNF in patients with LNR＜30% and≥30% was 4.4% and 14.0% (P=0.002).The 5-year CWR in the subgroups with LNR＜30% and≥30% was 3.5% and 9.6% (P=0.018).In age≤35 year eld patients with LNR≥30%,the 5-year RNF and CWR was 40.0% and 20.0%.In T2 patients with LNR≥30%,the 5-year RNF and CWR was 15.8% and 12.2%.Age and LNR were independent prognostic factors for RNF+CWR,LNR was the only independent prognostic factor for CWR by multivariate analysis. Conclusions In T1 or T2 breast cancer patients with 1-3 positive axiliary nodes treated with radical or modified radical mastectomy,a relatively high incidence of chest wall recurrence is observed in the subgroup of patients with lymph nods rate of 30% or greater accompanied by a T2 primary tumor or age≤35 years old. Lymph nodes rate is the only significant prognostic factor of chest wall recurrence.For these patients,post- operative lymphatic drainage area and chest wall irradiation should be considered.

To explore the application value of low-dose CT in lung cancer after operation in a short-term review by comparing conventional and low-dose CT. Methods:In 83 cases of lung cancer during the immediate postoperative period review, 50 cases (group A) underwent conventional CT scanning, whereas 33 cases (group B) underwent low-dose CT scanning. All CT scans were scored on the basis of image quality and clinical needs. The radiation dose indexes CTDIvol and DLP were recorded for each case. A comparison of the score and radiation dose between the two groups helped determine the existence of significant differences. Results:The average image quality scores of the two groups were 3.705±0.314 and 3.311±0.442, those for clinical demand were 2.670±0.373 and 2.561±0.410, those for CTDIvol were (19.248±1.532) mGy and (10.138±1.113) mGy, and those for DLP were (170.180±19.259) mGy*cm and (99.061±14.504) mGy*cm. The two groups exhibited significant differences in image quality, CTDIvol, and DLP but revealed no significant dissimilarity in clinical demand. Conclusion:Low-dose CT completely meets the clinical requirements for short-term follow-up after resection of lung cancer and significant reduction in radiation dose.

Objective To research the resilience and influencing factors of the plateau soldiers.Methods Resilience Scale for Adult (RSA),Symptom Checklist (SCL-90),Eysenck Personality Questionnaire (EPQ) and General Self-Efficacy Scale (GSES) was used in this study to 756 plateau soldiers.Results ①The high resilience has been found in plateau soldiers (2.78 ± 0.47 ).There were significantly differences in three education levels of the plateau soldiers in planned of future (F =3.261,P =0.039 ),family cohesion (F =6.428,P =0.002 ),structure style(F=4.135,P=0.016) and RSA scores(F=4.162,P=0.016),and college ＞ senior high school ＞ junior high school.②Compared to the lower group in the RSA,the higher group scored significantly higher in extraversion ( t =13.004,P =0.000) and self-efficacy ( t =12.956,P =0.000 ),while lower in SCL-90 ( t =10.308,P =0.000) and neuroticism( t =11.297,P =0.000).③Resilience had significantly positive relation with self-efficacy ( r =0.48 ) and extraversion ( r =0.46 ),and negative relation with neuroticism ( r =- 0.42 ) andSCL-90( r =-0.41 ).The self-efficacy extraversion and neuroticism have nice predictive ability (42％).Conclusion The Resilience of plateau soldiers are good condition,self-efficacy,extraversion,and neuroticism are important influencing factors for plateau soldiers.

AIM:To explore the association of the mutation in PPP2R3A exons and retinoblastoma.METHODS:Hospital-based case control study was taken.Retinoblastoma patients (15 cases, as case group) and matched controls (30 controls, as control group) were recruited in this study.Genomic DNA obtained from formalin fixed paraffin embedded (FFPE) and peripheral blood were used as template.PPP2R3A gene exon sequences were detected by PCR-sequencing.Homology analysis was performed using blastn in GenBank.RESULTS:Analyzing PPP2R3A DNA sequences (1001bp) from 15 cases, two reported SNPs had been detected, including rs34629706 and rs144802055.Rs34629706 also occurred in the control group.Rs144802055 appeared only in the case group.CONCLUSION:PPP2R3A gene SNPs of rs34629706 is unrelated to the incidence of retinoblastoma.Relations between rs144802055 and RB needs to be further explored.

The such solution with 1 ml/d was intragastrically administered to each rat in thyroid hormone-induced diardleic group.After three weeks,blood was sampled from vena caudalis of each rat.FT4 were then detected in blood semm.Fourty-two thyroid hormone-induced diarrheic rats were screened based on FT3 and FT4 level in blood serum, wet stool and body weisht.Fourty thyroid hormone-induced diarrheic rats were stochastically re-divided into 5 groups with 8 in each.The physiological saline with 1 ml/d was given to blank group,1.94 g·-kg-1·d-1 Berberine capsule to positive control group,and 0.63,1.26,2.52 g·kg-1·d-1 to low-dose,moderate-dose and high-dose groups respectivelv. Intragastric administration of each group continued for 7 days.Venous blood was centrifuged before and after administration and underwent radioimmunoassay to observe the effect of Ashi-antidiarrheal capsule on motillty (MTL),gastrin(GAS),somatostatin(SS),vasoactive intestinal polypeptide(VlP)in blood plasma of thyroid homlone- induced diarrheic rats.Results①Weight of thyroid hormone-induced diarrheic rats decreased[(344.0±12.9)g], FT3[(4,58 ±0.70)mol/L]and FT4[(23.44±4.40)mol/L]increased,and weight of wet stool[(17.4±3.2)g] increased.Compared to control group[(386.0±1.8)g,(2.08±0.10)mol/L,(10.18±2.00)mol/L,(9.1±0.6)g], there was a statistical significance(t=6.85,9.80,7.66,7.18,P<0.01).②After treatment,high-dose Ashi-antidiarrheal group[(80.54 ±3.80)ng/L]and positive control group[(90.63 ±9.99)ng/L]blood plasma MTL, compared to pre-therapy[(204.27±17.69),(187.79±13.32)ng/L]was decreased,there wag a statistical significance (t=8.60,4.57,P<0.01)③GAS contentshad respectively decreased comparedtopre-therapy[(192.75±11.80), (193.09±3.81),(190.60±9.31),(196.33±18.13)ng/L]in positive control group[(56.06 ±6.36)ng/L],low- dose group[(90.88±4.18)ng/L],midst-dose group[(75.64±7.09)ng/L]and hish-dose group[(44.32±3.72) ng/L],except for blank group.There Wag a statistical significance(t=15.27,7.62,13.43,13.22,all P<0.01).The intm-group difference of MTL,GAS and VIP level had statistic signifieances before and after the treatment(F= 166.68,1503.53,216.68,P<0.01).Conclusion Ashi-antidiarrheal capsule Can significantly lower the level of MTL and GAS in blood plasma。And raise the level of VIP.

Objective To study the effect of Asi-antidiarrheal capsule on gastrointestinal goblet cell of thyroid hormone-induced diarrhea.Methods Total of 120 SD male rats aged about 8 weeks were randomly divided into 2 groups:control group(10 rats)and thyroid hormone-induced diarrheic group(110 rats).Rats in control group were lavaged with normal saline 1 ml/d.Thyroid tablets were partly desolved into normal saline forming a 40 mg/ml suspension.Rats in thyroid hormone-induced diarrheic group were given the thyroid suspension 1 ml/d to make thyroid hormone-induced diarrheic model.Serum FT3 and FT4 were tested.Fourty thyroid hormone-induced diarrheic rats were screened out according to serum FT3 and FT4 levels,body weight and wet stool.The fourty rats were randomly divided into 5 groups,8 rats in each group:positive control group,berberine group,low-dose,mediandose and high-dose groups.Normal saline of 1 ml/d was admnistered to diarrhea control group,1.94 g·kg-1·d-1 Berberine capsule was given to positive control group,and 0.63,1.26,2.52 g·kg-1·d-1 Asi-antidiarrheal capsule to low-dose,mediandose and high-dose groups,respectively.After sever days treatment,rats are executed.Duodenum,jejunum,ileum and colon were dissected,respectively.Histology observation and cell counting were carried out under light micmscopo on HE coloration.Cell counting unit was defined as:cell/high power field of vision (cells/hpf).Results In jejunum,the number of goblet cells in berberine group,mediandose group and high-dose group[(15.32±2.53),(20.24±1.24),(14.98±1.10)cells/hpf,respectively],were all lower than that of the diarrhea control group[(25.73±4.55)cells/hpf,all P<0.05]with an exception of low-dose group[(23.98±2.28)cells/hpf].The numbers of goblet cells in berberine control group,low-dose group,mediandose group and highdose group[(18.29±1.33),(20.61±2.12),(19.38±2.01),(16.34±1.55)cells/hpf,respectively]were all less than that of the control group[(23.36±3.10)cells/hpf,all P<0.05].The numbers of goblet cells of diarrhea control group and high-dose group were obviously lower than that of the low-dose group(all P<0.05)in jejunum and colon.The numbers of goblet cells of Duodenum and ileum were not significantly different between groups(F=2.81,2.67,all P>0.05).The numbers of goblet cells in the diarrhea control group increased markedly observed under microscope,but decreased following therapeutic treatment.Conclusions The numbers of goblet cells from jejunum and colon in thyroid hormone-induced diarrheic rats are increased significantly.Asi-antidiarrheal capsule can remarkably decrease the number of goblet cells in jejunum and colon,and reduce mucus secretion.

BackgroundPterygia is a clinical common disease.A lot of surgical methods are developed to decrease the recurrence rate.Resent years,the application of fibrin glue is receiving more and more attention.Objective This study was to explore the effects of fibrin glue in decreasing inflammatory irritation and its mechanism. Methods Pterygia models were created in 12 clean rabbits by exsection of limbal tissue and topical administration of 1.25％ diluted hydrochloric acid,and then the conjunctival autograft surgery was performed in the experimental rabbits.The conjunctival flap was sutured in the left eyes,and the conjunctival wound was closed using fibrin glue in the right eyes.The operation duration for each group was documented and compared.The irritation sign was examined under the slit lamp in all the rabbits 1 week and 4 weeks respectively.The expressions of vascular endothelial growth factor (VFGF) and basic fibroblast growth factor (bFGF) proteins in the conjunctiva tissue were detected by immunochemistry,and the expressions of VFGF mRNA and bFGF mRNA in the conjunctival tissue were determined by reverse transcription polymerase chain reaction (RT-PCR).Results The operative duration was (21.3±0.2) minutes in suture group and( 10.1 ±0.1 )minutes in the fibrin glue group with a significant difference between two groups( t =102.242,P＜0.05 ).From 1 week through 4 weeks,the hyperemiain degree was obviously slight in fibrin glue group compared with suture group.Immunochemistry showed that VEGF and bFGF proteins were expressed mainly in the cytoplasm of conjunctival epithelium layer.The positive response intensity was weaker in the fibrin glue group than in suture group 1 week and 4 weeks after operation.RT-PCR revealed that the expression level of VEGF mRNA was significantly lower in fibrin glue group than in suture group,and the VEGF mRNA was gradually decreased with the time lapse ( Fgroup =174.443,P =0.000 ; Ftime =231.459,P =0.000 ).The similar outcomes were found in the expression of bFGF mRNA(Fgroup=41.727,P=0.000;Ftime=55.417,P=0.000). ConclusionsThe use of fibringluecanshortentheoperationdurationandreducepostoperationinflammatoryreaction.The downregulation of VEGF and bFGF in tissue is the possible mechanism of remitting irritation sign,which allows a reduce of the recurrence rate of pterygia.
