Objective To investigate the effect of comprehensive rehabilitation on the stroke.Methods 120 cases of stroke divided into rehabilitation group(60 cases)and control group(60 cases).They were assessed with Fugl-Meyer Assessment(FMA),Modified Barthel Index(MBI),and Satisfaction with Life Scale(SWLS)before and 1 month,3 months and 6 months after treatment respectively.Results The scores of FMA,MBI and SWLS were improved significantly in rehabilitation group,especially in the 1st month,while that of control group presented the tendency of decline.Conclusion Comprehensive rehabilitation is effective on motion function,activity of daily living and quality of life of stroke patients.

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 evaluate the efficacy of hydromorphone for patient-controlled intravenous analgesia (PCIA) after hip replacement in elderly patients.Methods Seventy patients, aged 65-75 yr, weighing 40-70 kg, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ , undergoing elective unilateral hip replacement, were randomly divided into either analgesia with hydromorphone group (group H, n =35) or analgesia with fentanyl group (group F, n=35).After a loading dose of 20 μg/kg of hydromorphone was injected at the beginning of skin closure, a PCA pump was connected, and the PCIA solution contained hydromorphone 0.25 mg/kg and tropisetron 10 mg in 120 ml of normal saline in group H.After a loading dose of 1 μg/kg of hydromorphone was injected at the beginning of skin closure, a PCA pump was connected, and the PCIA solution contained fentanyl 25 μg/kg and tropisetron 10 mg in 120 ml of normal saline in group F.The PCA pump was set up with a 0.5 ml bolus dose, a 15 min lockout interval and the background infusion at a rate of 2 ml/h in both groups.Tramadol 0.5 mg/kg was injects intravenously as rescue analgesic, and visual analogue scale score was maintained ≤ 3.The Ramsay sedation score,the number of attempts and the number of tramadol administration were recorded at 24 and 48 h after operation.The adverse effects within 48 h after operation and patient's satisfaction with analgesia were recorded.Results There was no significant difference in the Ramsay sedation score, the number of attempts and the number of Tramadol administration between H and F groups.Compared with group F, the incidence of adverse effects such as postoperative nausea, vomiting, respiratory depression, drowsiness, urinary retention, was significantly decreased, and the level of satisfaction with analgesia was increased in group H.Conclusion Hydromorphone provides accurate efficacy for PCIA after hip replacement in elderly patients, with fewer adverse effects and higher level of patient' s satisfaction.

Objective To investigate the relationship between androgen level and body adipose tissue content and distribution via a cross sectional survey in healthy women aged 40 to 60 years. Methods A total of 222 women were divided into 4 groups according menstruation status, i.e. reproductive stage, early perimenopausal stage, late perimenopausal stage and postmenopausal stage. Serum level of dehydroepiandrosterone (DHEA), total testosterone (TT) and sex hormone binding globulin (SHBG) were measured. Free androgen index (FAI) was calculated. Body adipose tissue content and distribution were measured by dual-energy X-ray absorptiometry. Results In women aged 40 to 60 years, DHEA, TT and FAI level of reproductive stage women was (12.3±4.1) nmol/L, (0.56±0.22) nmol/L and 1.15 (quartile:0.71 to 1.85), respectively. DHEA, TT and FAI level of early perimenopausal stage women was (12.0±3.4) nmol/L, (0.56 ± 0.24) nmol/L and 1.37 (quartile: 0.89 to 1.61), respectively. DHEA, TT and FAI level of late perimenopausal stage women was (14.2 ± 4.7) nmol/L, (0.62 ± 0.18) nmol/L and 1.38 (quartile:1.12 to 1.63). DHEA, TT and FAI level of postmenopausal stage women was (11.6±3.5) nmol/L, (0.45±0.22) nmol/L and 0.94 (quartile:0.47 to 1.49). DHEA, TT and FAI level of perimenopausal stage women was comparable with those of reproductive stage women (P>0.05), however, TT and FAI level of postmenopausal women was significantly lower than those of reproductive stage women (P=0.001, 0.014). The total adipose percentage of reproductive stage women, early perimenopausal stage women, late perimenopausal stage women and postmenopausal stage women were (35 ± 6)%, (35 ± 5)%, (37 ± 4)%and (37 ± 5)%. The adipose percentage in“android”area of reproductive stage women, early perimenopausal stage women, late perimenopausal stage women and postmenopausal stage women were (43±5)%, (43±4)%, (47±5)%and (46±5)%. The total adipose percentage was similar in 4 groups (P=0.312). Compared with reproductive stage women, adipose percentage of“android”area increased in late perimenopausal and postmenopausal women (P=0.026). Women with higher FAI level presented higher adipose tissue content and higher percentage of centrally distributed adipose tissue (r=0.28, P=0.003). Conclusions Body adipose tissue tends to distribute centrally from perimenopausal stage. Androgen level is related to body adipose tissue content and distribution, but may not be the main reason of changes of fat distribution in middle life women.

Objective To evaluate the clinical efficacy of Yinhe gargle on infected root canals. Methods Forty-seven cases of root canal infection ( involving 48 affected teeth) were randomly divided into two groups. The experimental group (22 cases involving 22 affected teeth) was given intracanal medicament with Yinhe gargle, and the control group ( 25 cases involving 26 affected teeth) was given root canal disinfection with camphor phenol. After intracanal medicament for one week, therapeutic effect and safety were evaluated in the two groups. Results ( 1) During root canal disinfection, none of the subjects had adverse reaction such as hypersensitiveness or cauterization of soft tissue. Canal obturation was available after the first intracanal medicament for the infected root canals. (2) After intracanal medicament for one week, the effective rate in the experimental group was 95.45%, and was 100.00%in the control group, the difference being in significant (P>0.05). Conclusion Yinhe gargle has similar disinfection effect to camphor phenol on infected root canals, and it can be used as disinfection medicament for root canals.

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.

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

Curriculum reform is very important to an university.In the Pharmaceutical Analysis Department,the principal for a curriculum plays a positive role not only in the teaching,but also in the scientific research and the service for the society.

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.
