ObjectiveTo analysis the clinical efficacy of using lateral homodigital flaps based on digital artery perforator to repair the fingertip defects. MethodsFrom October 2008 to August 2010,nine patients with twelve fingertip defects,including 5 thumbs,2 index fingers,3 middle fingers,2 ring fingers,underwent repair with lateral homodigital flaps based on digital artery perforator.The size of the flaps ranged from 2.7 cm× 1.4 cm to 3.1 cm× 1.8 cm.The donor site were covered by skin graft. ResultsEleven flaps survived.One case met with partial necrosis.The follow-up time ranged from 3 to 6 months(average of 4.5 months).The finges had good appearance.Ten cases had gained full postoperative sensory recovery and the two-point discrimination was 4-Smm at 3 months after operation.ConclusionUsing the flaps pedicled with digital artery perforator is a feasible solution for treatment of fingertip defects.

Objective To explore the impact of genetic background on pancreatic p-cell first-phase secretion function with L-arginine (L-ARG) stimulation test.Methods Plasma insulin level was detected in 201 cases before and after L-ARG stimulation test.Among them, 61 cases were newly diagnosed type 2 diabetic patients with family history of diabetes ( FH + DM ) , 55 newly diagnosed type 2 diabetic patients without family history of diabetes ( FH - DM) ,31 with normal glucose tolerance and family history of diabetes ( FH + ) 54 with normal glucose tolerance but without family history of diabetes ( FH - ).Homeostasis model assessment ( HOMA) was used to estimate insulin resistance (HOMA-IR).Results It was premised that gender, age and BMI were similar among the 4 groups.(1)TC,TG,fasting plasma glucose,2h plasma glucose,fasting insulin and HOMA-IR in the two groups of newly diagnosed type 2 diabetic patients with or without family history of diabetes were significantly higher than those in the two groups of normal glucose tolerance with or without family history of diabetes.The multiples of the peak level and the base level of insulin secretion in the groups of newly diagnosed diabetes were significantly lower than those in the groups of normal glucose tolerance with and without family history(P <0.05).(2) Insulin secretion reached a peak in 2 minutes and started to decline in 4 minutes in all the four groups.( 3 ) The multiples of the peak level and the base level of insulin secretion in normal glucose tolerance group with family history of diabetes were 20.8% lower than those in the group without family history, being 7.27 and 9.18 respectively ( P < 0.05 ).(4)Two-minute peak insulin secretion, HOMA-IR and age in the newly diagnosed type 2 diabetic group with family history of diabetes was significantly lower than these in the group without family history ( P < 0.05 ).The multiples of the peak level and the base level of insulin secretion in the newly diagnosed type 2 diabetic group with family history of diabetes and that group without family history were 5.18 and 5.31 respectively and there was no significant difference between the two groups( P >0.05).(5) When the normal glucose tolerance subjects with family history of diabetes progressed to suffer from diabetes, the multiples of the peak level and the base level of insulin secretion declined 43.6% (P < 0.05) more than those in the subjects still with normal glucose tolerance without family history.Conclusion In the early course of diabetes, insulin resistance dose not function significantly, but genetic background make the first-phase secretory function of the p-cell to decline gradually and type 2 diabetes occurs easily.In the absence of genetic background, insulin resistance makes first-phase the secretion of insulin to decline relatively slow.

Objective To explore the expressions of survivin and Ki-67 in breast cancer tissues after neo-adjuvant chemotherapy and their clinical significance.Methods The expressions of survivin and Ki-67 in 60 cases of breast cancer with neo-adjuvant chemotherapy(NACT) with CTF regimen and 60 cases without NACT were detected by SABC immunohistochemical technique.ResultsThe positive rates of survivin(36.7%)and Ki-67(38.3%) in neo-adjuvant chemotherapy group were significantly lower than those in control group(71.7%,61.7%)(P0.05).ConclusionsThe therapeutic effect of neo-adjuvant chemotherapy with CTF regimen can increase the remission rate of breast cancer.Neo-adjuvant chemotherapy could inhibit the expression of survivin protein,and thus further inhibit proliferation of tumor cell.

Objective:To conduct health economic evaluation of Chinese population-based screening and opportunistic testing strategies for the prevention of Helicobacter pylori ( H. pylori)-related diseases. Methods:The Markov models of H.pylori infection caused non-ulcer dyspepsia, peptic ulcer (PU) and gastric cancer were established. The cost and effects of the population-based screening, opportunistic testing, and non-intervention strategies in 100 000 population of our country were simulation calculated. Wilcoxon signed rank test was used for statistic analysis. Single factor sensitivity analysis was performed to analyze the impact of single parameter uncertainty on cost-effectiveness. Probability sensitivity was used to analyze the impact of common uncertainty of all parameters on cost-effectiveness. Results:Compared with opportunistic testing strategy and non-intervention strategy, the total cost of population-based screening strategy was reduced by 0.43 million yuan(-6.63 million yuan to 7.19 million yuan) and 4.45 million yuan(-8.60 million yuan to 27.93 million yuan), quality adjusted life years (QALY), life years and asmptomatic months were prolonged by 888.00 (479.86 to 1 574.10) and 3 032.78 (1 756.04 to 5 007.84), 651.82 (294.73 to 1 211.94) and 1 868.64 (1 045.88 to 3 148.34), 28 381.91 (19 109.54 to 43 736.72)and 102 537.13 (58 649.18 to 176 868.77) respectively, gastric cancer, deaths from gastric cancer, deaths from PU and deaths from various causes were reduced by 115 cases(52 cases to 232 cases) and 464 cases(266 cases to 803 cases), 74 cases(33 cases to 148 cases) and 260 cases(149 cases to 453 cases), 46 cases(25 cases to 72 cases) and 369 cases(210 cases to 710 cases), 80 cases(42 cases to 126 cases) and 501 cases(331 cases to 772 cases) respectively, and the differences were statistically significant ( Z=1.99, 10.54, 27.39, 27.39, 27.37, 27.39, 27.39, 27.39, 27.21, 27.28, 27.22, 27.28, 27.38, 27.39, 27.39 and 27.39, all P<0.05). Compared with the non-intervention strategy, the opportunistic testing strategy reduced the total cost by 3.89 million yuan(-2.79 million yuan to 18.18 million yuan), QALY, life years and asymptomatic months were prolonged by 1 764.77 (888.70 to 3 406.62), 1 044.16 (524.46 to 1 912.75) and 62 568.69 (30 054.07 to 129 892.76) respectively, gastric cancer, deaths from gastric cancer, deaths from PU and deaths from various causes were reduced by 311 cases(164 cases to 563 cases), 164 cases (87 cases to 301 cases), 325 cases(162 cases to 644 cases) and 399 cases(234 cases to 684 cases) respectively, and the differences were statistically significant ( Z=14.20, 27.39, 27.38, 27.39, 27.25, 27.25, 27.39 and 27.39, all P<0.01). The results of singlefactor sensitivity analysis showed that the uncertainty of any parameter did not affect the cost-effectiveness of three strategies. The results of probability sensitivity analysis indicated that the probability of cost-effectiveness advantage of the population-based screening strategy was 100% and the common uncertainty of all parameters had no effect on cost-effectiveness. Conclusions:For preventing H.pylori-related diseases, the population-based screening strategy has the lowest average cost and the best average effect. However, non-intervention strategy has the highest average cost and the worst average effect. Population-based screening strategy is worthy of promotion throughout China, and opportunistic testing strategy has a higher clinical practical value.

Objective To investigate the status quo of nutrition knowledge,attitude and practice(KAP) among elite female small ball athletes of Guangdong province and its influencing factors.Their serum ferritin was also observed to explore its correlation with their KAP,so as to provide evidences for formulating and implementing scientific and reasonable nutrition education schemes.Methods Fifty-four female small ball athletes,including 20 handball,20 hockey and 14 softball players,were selected to complete a self-designed diet questionnaire based on KAP education mode and their serum ferritin indicators were analyzed at the same time.Results (1)The average scores(all out of 100)of nutrition knowledge (K),attitude (A) and practice (P) were 43.64 ± 11.66 (with a failure rate of 90.7％),78.37 ± 10.21 (with the rate of excellence of 59.3％)and 63.10 ± 10.17(with a passing rate of 37.0％),and the average KAP score was 185.10 ± 23.01,with a passing rate of 44.4％.(2)The one-way ANOVA found that there were significant differences in the average A score and the total KAP score (P＜0.05) among the athletes of different small ball teams.The correlation analysis results showed that the average A score was of significant positive correlation to the average P score.Moreover,the average KAP total score was of significant correlation with sports events (P＜0.05) and the education level (P＜0.05),but not with the age,training period and exercise level(P＞0.05).The multiple stepwise regression analysis results showed that training period(P＜0.05) and sports events(P＜0.05) was the influencing factor of nutrition knowledge and attitude respectively,and that education level (P＜0.01) was the influencing factor of both nutrition practice and KAP.(3)Significant differences were found in the serum ferritin among athletes of different sports events(P＜0.05)the serum ferritin was of significant positive correlation with the nutrition knowledge(P＜0.05).Conclusion (1)The lack of sports nutrition knowledge and the unbalance of nutrition behavior are common in elite female small ball athletes,but they had a positive attitude.It is necessary to carry out a series of effective nutrition education programs to improve their sports nutrition knowledge,cultivate their good nutrition attitudes and finally formulate rational and effective nutritional intervention measures to promote the formation of healthy nutrition behavior of athletes.(2) The sport event is the key influencing factor of the nutrition attitude and dietary behaviors,which suggests that more more attention should be paid to athletes' dietary management and focus should be put on their diary behavior on no-training days and on their energy ratios control of each meal,especially breakfast and extra meals,and rational intake of snacks.(3)The incidence of iron deficiency is consistent with KAP questionnaire survey results,which indicates that it may be an effective measure to prevent iron deficiency anemia through strengthening athletes' dietary nutrition education.

Background The pathogenesis of dry eye has not been clearly established.There are more and more evidences to suggest that it is associated with ocular surface inflammation mediated by immunity.But how T helper cell 17 (Th17) plays its role in dry eye remains unclear.Objective The aim of this study was to investigate the expressions of Th17 related cytokines in ocular surface with dry eye.Methods A prospective cohortl study was designed.This protocol was approved by Ethic Commission of Peking University Third Hospital,and written informed consent was obtained from each subject prior to entering this cohort.Twenty female patients with Sjigren syndrome (SS group),20 patients with non-SS dry eyes and 20 normal volunteers were recruited in Peking University Third Hospital during 2011-2012 duration and all the subjects were menopausal female with the age 50 years old or more.The ocular surface disease index (OSDI)questionnaire designed by Schiffman was performed firstly,and then tear breakup time (BUT),corneal fluorescein staining and Schirmer Ⅰ test (S Ⅰ t) were carried out in the subjects.Expression of Th17 related cytokines mRNA were measured using PCR-Array.The correlation between IL-17A and ocular surface parameters was analyzed.Results The OSDI scores of the SS dry eye group,non-SS dry eye group and normal control group were 50.00 (33.50,66.50),45.00 (35.50,55.00) and 3.00 (0.00,5.00),the S Ⅰ t values were 2.50 (1.00,4.00),5.00 (2.00,5.00) and 15.50 (10.00,18.50),the BUT were 2.00 (1.00,4.00),4.00 (3.00,5.00) and 10.00 (10.00,12.00),the corneal fluorescein staining score were 8.50 (6.00,12.00),5.50 (4.00,7.00)and 0.00 (0.00,0.00),respectively,and significant differences were seen among the SS group,non-SS dry eye group and normal control group (x2=34.11,28.13,93.66,92.25,all at P＜0.01).The relative expression values of IL-17A mRNA,IL-6 mRNA,IL-8 mRNA,IL-22 mRNA and IL-23 mRNA in the ocular surface were 1.98±0.16,11.64±1.32,6.67±1.12,1.88±0.18 and 1.78±0.17 in the SS group patients,and 1.45±0.17,1.32±0.14,1.12 ±0.13,1.23 ±0.15 and 1.23 ±0.13 in the non-SS dry eye group patients,respectively,with significant differences between the two groups (all at P＜0.01).IL-17A level on the ocular surface was significantly negative correlated with BUT (r =-0.56,P＜0.01) and positive correlation with corneal fluorescein staining scores (r=0.44,P=0.01).Conclusions Expressions of Th17 related cytokines in the ocular surface increased in patients with dry eye,especially in those with SS.IL-17A level in ocular surface is associated with BUT and corneal fluorescein staining scores,suggesting that immune is involved in the pathogenesis and devlopment of dry eye.

Objective To investigate the incidence rate, high risk factors and hemodynamic changes of patent ductus arteriosus (PDA) in premature infants, and to give suggestions abo ut clinical monitoring and management of PDA in premature infants. Methods Echocardiography was performed on 86 non-ventilated or weaned from ventilator-pr emature infants at 2 to 5 days of age,whose gestational age was 28 to 36 weeks. All premature infants diagnosed as PDA were followed up clinically and by Echoc ardiography until discharged. Results Twenty-two infants diagnosed as PDA at mean 3 days of age, mean gestational age was (33.l?2.0) weeks. Ductus in 16 infants (out of 20 infants) closed spontaneo usly when repeated echocardiography at mean 8.5 days of age. For 4 remaining PDA infants, ductus closed in 2 cases (l treated with indomethacin). One ductus reo pened because of sepsis, and 3 infants discharged with opened ductus at their 2l , 40 and 47 days of age respectively. Single and multiple Logistic analysis indi cated that the lower the birth-weight ,the higher the incidence of PDA (?2=2. 8907 P=0.0891); neonatal asphyxia and suffered from severe diseases (neonat al respiratory distress syndrome, sepsis) were high risk factors of PDA (?2= 4.3729 P=0.0365;?2=11.6590 P=0.0006). Premature infants with PDA h ad good heart function,although their LA/AO ratio increased slightly (1.0810?0. 18 vs 1.00?0.07,P= 0.048).Conclusions PDA incidence at 3 days of life in 33 weeks premature infants is 25.6%, 85% PDA disappeares spontaneously during follow-up. Low birth-weight asphyxia, severe diseases and symptomatic PDA are high risk factors of PDA. Ductus can reopen in premature infants. J Appl Clin Pediatr,2005,20(2):129-131
