Objective To explore the effect of early systemic phased exercise post mastectomy on the recovery of activities of daily living. Methods 100 patients who received modified radical mastectomy were assigned to the experimental group and control group with 50 patients in each group. They all accepted routine nursing, and the experimental group accepted early systemic phased exercise in addition. They were assessed with range of motion (ROM) of shoulder and modified Barthel Index (MBI). Results ROM of shoulder improved in 90% of the experimental group and 70% of the control group (P<0.05). MBI was (84.5±18.2) in the experimental group and (51.8±16.6) in control group (P<0.05) . Conclusion Early systemic phased exercises may promote the recovery of the affected arm for the patients post mastectomy.

Objective To evaluate the effect of rocuronium on entropy to endotracheal intubation during anesthesia induction with propofol. Methods Forty patients anesthetized induction with propofol using a target-controlled infusion were randomly divided into two groups: rocuronium group (R group, 20 cases) received 0.6 mg/kg rocuronium or saline group (S group, 20 cases) received saline. 2-3 min later, endotracheal intubation was performed. Response entropy(RE) and state entropy(SE) were recorded during baseline(Ta), at steady state(Tb), 2 min after rocuro nium or saline administration (Tc) and 0, 1, 2 and 3 min after endotracheal intubation (T0, T1, T2, T3). Results At T2, the RE-SE was higher in S group than that in R group. Endotracheal intubation induced increasing in RE and SE. Comparing T2 and T0 values in R group and S group, SE increased from 42 ± 7 to 50 ± 8 and 43 ± 13 to 55 ± 12, and RE increased from 45 ± 6 to 54 ± 9 and 48 ± 16 to 66 ± 15, respectively. At T0, RE and RE-SE were higher in S group. Conclusion Rocuronium affects RE-SE and RE and RE-SE responses to endotracheal intubation and may confound interpretation of entropy monitoring.

Objective To evaluate the efficacy of fexofenadine hydrochloride tablets at tapering doses for the treatment of chronic spontaneous urticaria. Methods After receiving evaluation of medical history and undergoing autologous serum skin test (ASST), 80 patients with chronic spontaneous urticaria were randomly divided into two groups:conventional dose group administrating fexofenadine hydrochloride tablets 120 mg/d for 12 consecutive weeks, tapering dose group administrating fexofenadine hydrochloride tablets 120 mg/d for the first 4 weeks followed by dose tapering of fexofenadine hydrochloride tablets by 30 mg at the 5th and 9th weeks. The urticaria activity score(UAS) and dermatology life quality index(DLQI)were evaluated before the treatment(baseline)as well as after 4?, 8?and 12?week treatment, and the total dose of fexofenadine hydrochloride was calculated. Results A total of 76 patients completed the 12?week treatment, including 37 patients in the conventional dose group and 39 patients in the tapering dose group. After 4?, 8?and 12?week treatment, a significant decrease was observed in the UAS in the conventional dose group(0.64 ± 0.82, 0.37 ± 0.68 and 0.27 ± 0.56 vs. 4.08 ± 0.79, all P<0.01)and tapering dose group(0.61 ± 0.87, 0.48 ± 0.72 and 0.28 ± 0.61 vs. 4.07 ± 0.81, all P<0.01)compared with that at baseline in the corresponding groups. DLQI scores also significantly decreased after 4, 8 and 12 weeks of treatment in the conventional dose group(3.62 ± 1.82, 2.81 ± 1.65 and 1.37 ± 1.14 vs. 16.19 ± 3.79, all P<0.01)and tapering dose group(3.79 ± 2.57, 2.74 ± 2.11 and 1.15 ± 1.47 vs. 15.92 ± 4.2, all P < 0.01) compared with those at baseline. However, there were no significant differences in the UAS or DLQI scores between the conventional dose group and tapering dose group at any of the post?treatment time points(all P>0.05). After 8?and 12?week treatment, symptoms were controlled in 71.79%(28/39)and 82.05%(32/39)of patients in the tapering dose group, respectively, with the total dose of fexofenadine hydrochloride being significantly lower in the tapering dose group than in the conventional dose group (both P<0.001). Conclusion After 4- 8 weeks of treatment with fexofenadine hydrochloride, the tapering dose regimen and conventional dose regimen show similar clinical efficacy in patients with chronic spontaneous urticaria.

Objective To investigate the effects of three external nasogastric tube fixations on unplanned nasogastric tube removal after radical esophagectomy for esophageal cancer.Methods Two hundred and thirty four esophageal cancer patients who underwent radical esophagectomy with nasogastric intubation were assigned into conventional group I(n=74),conventional group II (n=79)and experiment group(n=81)using random number table.For external fixation of the nasogastric tube,the traditional group I used“3M”silk tape,the traditional group II used a white flat strap with two knots and the experiment group used anI-shaped nasal fixation tape combined with a flapping cheek fixation tape.The three groups were compared in terms of displacement of the indwelling nasogastric tube and slippage of the tube.Results The displacement rate of nasogastric tube and the rate of slippage in the experiment group were both significantly lower than those in both conventional groups I and II(all P<0.05).Conclusion TheI-shaped nasal fixation tape combined with a flapping cheek fixation tape in fixing the nasogastric tube can effectively reduce the incidence of unplanned removal of nasogastric tube and meanwhile the patients may feel comfort and satisfactory.

Objective To explore the prognostic value of N-terminal pro-brain natriuretic peptide ( NT-pro-BNP) levels in critically ill infants. Methods Eighty-one critically ill infants were enrolled from January 2013 to January 2014 in pediatric intensive care unit. The minimum of pediatric critical illness score ( PCIS) and the number of dysfunction organs were calculated within 24 hour after admission. According to PCIS,the critically ill infants were divided into extremely critical group(PCIS≤70,n=25),critical group (PCIS 71-80,n=30)and non-critical group(PCIS>80,n=26). According to the prognosis,the critically ill infants were divided into survival group (n=68)and death group(n=13). The serum NT-pro-BNP levels were determined on the first day,third day and convalescent phase. The relationships of serum NT-pro-BNP levels with PCIS and the number of dysfunction organs and prognosis were observed. Results The study showed statistical significances of serum NT-pro-BNP levels among the extremely critical group, critical group and non-critical group,whether on the first day,or on the third day and convalescent phase(P<0. 01). There were statistical significances of serum NT-pro-BNP levels among different stages of the disease in each group(P<0. 01). Compared with survival group,PCIS was significantly lower and the serum NT-pro-BNP levels and the number of dysfunction organs were significantly higher in death group. The serum NT-pro-BNP level on the third day was higher than that on the first day in death group ( P<0. 01 ) , while no significant difference was found in survival group. The serum NT-pro-BNP levels on the first day and the third day and PCIS were negatively correlated(r= -0. 59,P<0. 01;r= -0. 66,P<0. 01). The serum NT-pro-BNP levels on the first day and the third day and the number of dysfunction organs were positively correlated(r=0. 40,P<0. 05;r=0. 57,P<0. 01). Conclusion The serum NT-pro-BNP levels of the critically ill infants are correlated with disease severity,and can be useful for assessing the severity of critical illness.

OBJECTIVE To investigate theradiosensitization of combined inhibition of signal transducer and activator of transcription 3(STAT3) and hypoxia-inducible factor-1α(HIF-1α)on laryngeal squamous carcinoma of xenograft mice and its underlying mechanisms.METHODS Xenograft mice were divided into 5 groups randomly: control group(A), irradiation group(B), irradiation and AG490 group(C), irradiation and PX478 group(D), irradiation combined AG490 and PX478 group(E). The size of xenograft tumor was measured and calculated. The expression of Ki67 and HIF-1α was detected by immunohistochemical method. Western blot was used to detect the expression of PARP1.RESULTS The size of xenograft tumor in group E was smaller compared with that in group C and group D. There were significantly difference between them respectively (t=12.367,11.598,P=0.000). The expression of HIF-1α in group E was lower than that in group C and group D respectively, and there were significantly difference respectively(t=5.422, 3.000,P<0.05). Ki67 index in group E was lower compared with that in group C and group D respectively and there were significantly difference respectively (t=4.479, 4.352,P<0.05). The level of cleaved PARP-1 in group E was higher than that in group C and group D respectively and there were significantly difference respectively (t=5.507, 7.102,P<0.05). CONCLUSION Combined inhibition of STAT3 and HIF-1α can increase the radiosensitivity of human laryngeal squamous carcinoma in the xenograft mice.

Aim To investigate the effects of isoliquiri-tigenin ( ISL) on anti-angiogenesis both in vitro and in vivo and its mechanisms. Methods We assessed the antiangiogenic activities of ISL on proliferation viabili-ty, migration and tube formation of human microvascu-lar endothelial cell line-1 (HMEC-1) in vitro. The cell proliferation viability was assessed using the Sulforho-damine B ( SRB ) assay. Modified Boyden Transwell chamber assay was done to study the effect of ISL on HMEC-1 cells migration. 2′, 7′-dichlorofluorescein di-acetate ( DCFH-DA) was used to measure the levels of intracellular reactive oxygen species ( ROS ) , which was induced by VEGF. Metalloproteinase-2 ( MMP-2 ) and metalloproteinase-9 ( MMP-9 ) expressions by HMEC-1 cells were assessed through gelatin zymogra-phy assay. HMEC-1 cells cycle was detected by flow cytometry. Moreover, we investigated the in vivo anti-angiogenic activity of ISL on chicken embryos nap al-lantoic membrane model ( CAM ) . Results ISL con-centration-dependently inhibited the growth of HMEC-1 cells as well as SW620 and A549 cells. ISL signifi-cantly and concentration-dependently suppressed the migration activity of HMEC-1 cells. Tube sample struc-ture formation further confirmed the effect of ISL on an-ti-angiogenesis. Moreover, ISL also inhibited intracel-lular ROS level, MMP-2 and MMP-9 expression by HMEC-1 cells. ISL induced endothelial cell apoptosis at a low concentration ( ISL 12 . 5 μmol · L-1 ) and blocked the cells in S phase of mitosis at higher con-centrations ( ISL 25~100 μmol·L-1 ) . Furthermore, ISL distinctly inhibited the angiogenesis of chick em-bryos in vivo. Conclusions ISL has anti-tumor and angiogenesis effects on HMEC-1 cells. The mechanism may be related to intracellular ROS scavenging and ap-optosis induction of HMEC-1 cells.

BACKGROUND: The principal deterrent to the success for hematopoietic stem cell transplantation (HSCT) is the complications after transplantation. The complications are associates with the conditioning regimens in the early stage. The highly-effective preparative regimens of proper dose and low-toxicity are the key to the successful HSCT.OBJECTIVE: To evaluate the curative effects and regimen related toxicity (RRT) of high-dose alkylating-agent-based chemotherapy as conditioning regimens for HSCT in the patients with hematological malignancies.DESIGN: Controlled study with observation.SETTING: Department of Hematology, Affiliated Hospital of Xuzhou Medical College.PARTICIPANTS: A total of 45 patients with leukemia and lymphoma hospitalized at Affiliated Hospital of Xuzhou Medical College from July 1997 to February 2006 were enrolled, including 31 males and 14 females. The median age was 31 years (from 7 to 52 years). The median course was 8 months (from 5 to 17 months) until transplantation.METHODS: Totally 45 patients with leukemia and lymphoma approached or got complete remission were treated by bone marrow transplantation and peripheral blood stem cell transplantation with preparative regimens of high-dose alkylating-agent-based chemotherapy. RRT was graded according to Bearman proposal, from grade 0 (no toxicity) to grade Ⅳ (fatal toxicity). The period of hematopoietic reconstitution, the rates of complete remission and relapse and disease-free survival were statistically observed in transplant recipients.MAIN OUTCOME MEASURES: Occurrence of RRT as conditioning regimens.RESULTS: ①Five patients did not show any toxicity. The greatest toxicity of grade Ⅲ was uncommon (13%, 6/45). Most of the cases with RRT were in grade Ⅰ - Ⅱ and severe oases in grade Ⅲ were rare. In grade Ⅰ - Ⅱ, stomatocace and gastrointestinal toxicity were common respectively of 73% (33/45) and 51% (23/45) which were recovered in short time after treatment; Heart toxicity was rare and only in grade Ⅰ, most of which were tachyoardia and changes of ST-T shape. The increase of transaminase was common in the clinical manifestations of liver RRT except two cases of HVOD.There were four oases of HC, in which one was delayed. RRT on kidney, lungs and CNS was uncommon. ②Totally 43 patients engrafted gained hematopoietic reconstitution, 2 patients died of implant failure (4%). Within the median follow-up period of 37 (8-102) months, 10 patients relapsed, 5 patients died of transplantation-related complications and 28 patients were alive in a disease-free situation (62.2%). The cause of death within 100 days after transplantation was ordinal as acute graft-versus-host disease (GVHD), cytomegalovirus (CMV) interstitial pneumonia, disseminated infections,multiple organ failure and early relapses.CONCLUSION: Alkylating-agent-based conditioning regimens may be well tolerated with low toxicities for HSCT in leukemia and lymphoma.

Objective To determine the polymorphism in CXC chemokine SDF-1α transcript and its effects on HIV infection.Methods Three groups of study subjects lived in Hang Kong were recruited:278 HIV-heahhy donors of Chinese origin.49 HIV+Caucasians and 13 Chinese with high risk behavior to HIV but kept uninfected.Genomic DNA and RNA were extracted from eripheral blood mononucleal cell. The PCR and RT-PCR reaction were set up accordingly.Sequence of the SDF-1α promoter,the open reading frame(ORF)and the 3'untranslate region(3'UTR)were analyzed.Two steps PCR reaction using two reverseprimers with mismatched nucleic acid were employed to screen the frequency of a novel mutation. Results equencing analysis from 100 subjects indicated that non mutation happened in tlle promoter and ORF of SDF-1α.A novel mutation Was detected from 3'UTR of SDF-1α.It is a "GA" insertion in "G" rich region near the stop code of SDF-1α.The mutation Was named as SDF-1-3’GA+and submitted to GenBank (AY874118).The mutation happened in three roups.with allele frequency of 15.1% in the healthy Chinese.of 30.7% in the high risk Chinese group.Conclusions our results confirm that SDF-1 genes arerelatively conserved.None noteworthy mutation is identified in the promoter and ORF regions of SDF-1α However.a novel mutation is identified from the 3'UTR of SDF-1α. It would be worthwhile to etermine effect of the novel mutation on HIV infection.
