Objective To determine the analgesic effects of flurbiprofen axetil injection on orthopedic surgery patients.Methods Seventy-eight orthopedic surgery patients were randomly divided into control group ( n=39 ) and test group ( n=39 ).Patients in control group were given intravenous administration of parecoxib 20 mg at 15 min before anaesthe-sia induced by propofol 1-2 mg · kg -1 and maintained by isoflurane in operation; after operation , 60 mg of parecoxib dissolved in 100 mL 0.9%NaCl was intravenously dripped.Patients in test group were given the same treatment beside the 20 mg of parecoxib was changed to 50 mg of flurbiprofen axetil.Average artery pressure ( MAP ) and heart rate (HR), visual analogue score ( VAS), Ramsay sedation score ( RSS), levels of serum C reactive protein ( CRP ) , prostaglandin E 2 ( PGE2 ) and incidence of adverse drug reactions of the two groups were observed.Results The MAP and HR, VAS, RSS of two groups showed no statisti-cal significance expect the VAS at moment post surgery; the content of serum CRP in test group at postoperative 24 h was ( 16.77 ±5.52 ) mg · L-1 , significantly lower than that of control group of ( 20.68 ±7.76 ) mg · L-1 ( P<0.05 ); the PGE2 content in test group had no significant difference with control group ( 135.1 vs 141.6 pg · mL -1 , P >0.05 ).The incidence of adverse drug reaction in test group was significantly lower than that in control group (7.7%vs 20.5%, P<0.05 ).Conclusion Flurbiprofen axetil injection can reduce the stress reaction of orthopedic surgery patients , the incidence of side effect was also lower.

OBJECTIVETo investigate the effect of vascular bundle implantation in autogenous bone graft on angiogenesis.

METHODSThirty-six New Zealand white rabbits were evaluated in this study. A portion of bilateral radial bones of a rabbit were removed as free bone grafts, whose periostea were peeled off. In test group, the external maxillary artery bundle was passed through the marrow cavity of the bone. In control group, there was no vascular bundle implantation. Each bone was placed in masseter muscle separately. The rabbits were sacrificed and the specimens were procured at 3 days, 1, 2, 3, 4 and 6 weeks after surgery for histological observation, Chinese ink perfusion and CD34 immunohistochemistry. Microvessel density (MVD) was assessed in order to evaluate angiogenesis of autogenous bone grafts.

RESULTSThe bone grafts were found revascularization in 3 days after surgery in the test group, whereas at 2 weeks in the control group. In 3 days, 1 week, 2 weeks, 3 weeks and 4 weeks after surgery, the MVD of test group was significantly higher than that of control group. In 4 weeks after surgery, angiogenesis of test group reached to peak.

CONCLUSIONVascular bundle implantation improved angiogenesis in non-vascularized autogenous bone graft in this study.

The metabolism, distribution and excretion profiles of recombinant human thrombopoietin (rhTPO) in mice were studied by means of (125)I-labeled rhTPO ((125)I-rhTPO) combined with size exclusive high performance liquid chromatography (SHPLC) or trichloroacetic acid (TCA) precipitation analysis. (125)I-rhTPO was prepared by iodogen method. Purification was performed on Sephacryl S-200 HR gel. Radioactive-purity of (125)I-rhTPO identified by SHPLC was (96.9 +/- 1.5)% (n = 3). The proliferation effect of TPO dependent cell line (TD-3) and the increase of peripheral platelet counts in mouse by (125)I-rhTPO demonstrated that (125)I-labeled protein maintained the biological activities of TPO both in vitro and in vivo. SHPLC analysis of serum and urine samples taken after sc 1 micro g/mouse (345 kBq/mouse) of (125)I-rhTPO revealed that there were two lower molecular weight (125)I-degradation metabolites ((125)I-MI and (125)I-MII) other than parent molecule. (125)I-MI was mainly found in urine, and (125)I-MII was detected both in serum and in urine. The maximal concentration of (125)I-rhTPO was reached at 2 hours after injection. The terminal half-life was 10.8 hours, which was much longer than those of other peptides. TCA precipitable radioactivity in tissue showed that the radioactivity in bone marrow was rather high. The highest level was found in urinary system. Levels in adrenals, lymph nodes, and fat were near to that in serum. Lowest was found in brain. The main excretion route was urinary system and (98 +/- 5.6)% of (125)I-rhTPO was excreted within 72 hours after dosing.

This article provides an overview of metastases to jaws (MJ), mainly concerning the differences between American and Chinese patients, and exploring the relationship between the primary tumors' prevalence (PTP) and constituent ratio of MJ. Information concerning of 399 MJ cases in 215 papers, including one new case in our hospital, was subjected to statistic analysis. The main clinical features of MJ, such as constituent ratio of PTP and that of MJ, metastatic sites, treatments, and prognosis were summarized. Breast, lung, kidney, prostate and thyroid (in descending order) were the leading primary sites of MJ. Furthermore, the constituent ratio of MJ was found to be correlated with that of PTP in all subjects including American and Chinese subjects in our study. As to metastatic sites in the mandible, a specific "M" shaped pattern appeared regardless of the tumor type or constituent ratios of MJ were in all subjects. Almost all subjects received traditionally palliative treatments, and the prognosis was quite poor. The PTP had a significant impact on the constituent ratio of MJ. However, it was the properties of the microenvironment rather than characteristics or constituent ratios of tumor cells, that decided the metastatic sites in various tumor subjects.

OBJECTIVETo assess the risk factors for vulvar dystrophy.

METHODSAn epidemiological study was carried out. Data on 100 cases with vulvar dystrophy was reviewed and face to face interviewed with a uniform questionnaire including the manner of work, environmental temperature, habit of eating, mood, underwear wearing, autoimmune diseases, marriage, menstrual age, the quantity of menses, orders of pregnancy, and labor trauma of vulvar during delivery, vulvitis and urethritis ect. Univariable analysis and multivariate logistic regression analysis were carried out with 1:1 case-control methodology.

RESULTSMultiple conditional logistic regression analysis showed that vulvar dystrophy was positively associated with hot food (OR = 2.55, 95% CI: 1.24 - 5.25), mood (OR = 4.27, 95% CI: 1.96 - 9.29), order of pregnancy (OR = 3.37, 95% CI: 2.11 - 5.40), vulvitis (OR = 6.74, 95% CI: 2.66 - 17.09) and urethritis (OR = 11.02, 95% CI: 1.01 - 120.19). Vulviitis or urethritis increased 6.74 or 11.02 times the incidence of vulva dystrophy. Anger or nervous state contributed to the incidence of vulva dystrophy (OR = 4.27). Addict to hot food and order of labor also increased risk ratio for 2.55 and 3.37 times, respectively.

CONCLUSIONThe risk factors of vulvar dystrophy were: addict to hot food, often holding a angry or nervous state, increase of labors, having vulvitis and urethritis.

Objective To explore the significance of modified pediatric early warning score (MPEWS) in emergency early warning triage and classification. Method Selecting ill children who came to emergency department from February of 2017 to January of 2018 as objects of study, and triage nurses of emergency department gave MPEWS to the sick children under the demand of the filed data collection. Furthermore, according to the five levels of disease severity classification, doctors gave the disease assessment and classification to the sick children, finding the relevance between the MPEWS and the severity of the disease.Result Consequently, there is a relevance between the MPEWS scores and the severity of the disease indeed (rs=-0.630, P ＜ 0.001). The data show that the higher of the scores, the lower disease level, and the higher severity of the disease. ROC areas under the curve of the subjects is 0.996, and the confidence interval is 0.993-0.999 (P ＜0.05). That indicates that MPEWS exists statistical significance of emergency children judgement. The optimal number is 4.5, the sensitivity is 96％, and the specificity is 99.9％.Conclusions MPEWS is valuable in emergency early warning triage, children emergency severity assessment and identifying critical ill children in time.

BACKGROUNDSix provinces in China accounted for 70% - 80% of all reported HIV/AIDS cases in the country in 2009 and five provinces accounted for 78% of all reported mother-to-child transmission (MTCT) of HIV cases. Because Guangxi belonged to both groups, the Prevention of Mother-to-Child Transmission (PMTCT) Plus program was established there to understand better low birth weight (LBW) and preterm delivery (PD) birth outcomes and their associated risk factors better.

METHODSPregnancy outcomes were examined among HIV-infected pregnant women who enrolled in the PMTCT Plus program from June 2006 to February 2009 in Guangxi, China. Multivariate Logistic regression analysis was used to explore the risk factors associated with LBW (< 2500 g) and PD (gestational age < 37 weeks).

RESULTSThe prevalence of LBW and PD among 194 HIV-positive mothers was 19.6% (38/194) and 9.8% (19/194), respectively. Multivariate Logistic regression analysis showed that CD4 cell count < 100 cell/µl (multivariate-adjusted odds ratio (AOR) 5.52; 95%CI 1.11 - 25.55) and CD4 cell count 100 - 199 cells/µl (AOR 3.40; 95%CI 1.03 - 11.25, compared to CD4 cell count ≥ 350 cells/µl), gestational age < 37 weeks (AOR 4.38; 95%CI 1.29 - 14.82, compared to ≥ 37 weeks), maternal weight < 45 kg (AOR 5.64; 95%CI 1.09 - 29.07) and maternal weight 45 - 54 kg (AOR 3.55; 95%CI 1.31 - 9.60, compared to ≥ 55 kg) at enrollment, and HIV RNA ≥ 100 000 copies/ml at enrollment (AOR 4.22; 95%CI 1.24 - 14.32) and 20 000 - 99 999 (AOR 2.77; 95%CI 1.01 - 7.77, compared to < 20 000 copies/ml) were associated with a higher risk of LBW. For PD, only maternal injection drug use as the route of HIV transmission (AOR 5.30; 95%CI 1.33 - 21.14, compared to those infected with HIV through sexual transmission) was significantly associated with a higher risk of PD.

CONCLUSIONSLower CD4 cell count and higher HIV RNA viral load at enrollment were associated with LBW. Optimal antenatal care, including earlier antenatal screening and HIV diagnosis, is critical to earlier PMTCT prophylaxis and/or HIV treatment to prevent transmission of HIV to the infant and also to prevent LBW pregnancy outcomes.

OBJECTIVETo screen the sensitive chemotherapeutic agents to human endometrial carcinoma cell line-1 (HECCL-1) and study its mechanism.

METHODSMTT method was used to examine the relative inhibition ratios (RIRs) of various concentrations of 18 chemotherapeutic agents to HECCL-1. Cell cycle, apoptosis and expression of MDR1 protein were detected by FCM.

RESULTSNine of the chemotherapeutic agents studied obviously inhibited the proliferative activity of HECCL-1 in a dose-dependent manner. The order of sensitivity was as follows: adriamycin (ADM), oxaliplatin (L-OHP), carboplatin (CBP), cisplatin (DDP), taxol (TAL), epirubicin (EPI), mitoxantrone (MIT), dactomycin (ACTD) and 5-fluorouracil (5-Fu). FCM showed these agents could significantly reduce the proportion of cells in G0-G1 phase, and increase the proportion of cells in S and G2-M phase (P < 0.05). Cell apoptosis was observed in 11 chemotherapeutic agents at their peak concentration. MDR expression was induced after using EPI, 5-Fu, hydroxycamptothecin (HCPT) and MIT.

CONCLUSIONHECCL-1 is sensitive to a number of the chemotherapeutic agents studied. Induced apoptosis may be the major mechanism of drug sensitivity, and acquired drug-resistance may be the critical reason against continued administration.

OBJECTIVETo study the role of carbamyl phosphate I (CPS-I)and ornithine transcarbamoylase (OCT) levels in cirrhosis patients with and without hepatic encephalopathy, and to analyze the correlations between CPS-Iand OCT with the development of hepatic encephalopathy.

METHODSCPS-I, OCT, plasma ammonia and liver function of 95 cirrhosis patients with hepatic encephalopathy and 25 cirrhosis patients without hepatic encephalopathy in our hospital from January 2008 to December 2009 were analyzed. 60 healthy controls were recruited in the control group. The differences of serum CPS-I, OCT levels among the cirrhosis patients with and without hepatic encephalopathy and the healthy controls were analyzed; the correlations of CPS-I, OCT levels with plasma ammonia and total protein in cirrhosis patients,and the correlations of CPS-I, OCT levels with Child-Pugh classification of cirrhosis symptom severity in cirrhosis were analyzed. the clinical characteristics between patients who had HE and no HE with chi-square tests were compared. Comparisons of CPS-I, OCT levels across patients based on the Child-Pugh classification were performed with One-Way ANOVA and Student-Newman-Keuls, correlation of CPS-I, OCT with other indicators were performed with Pearson correlation analysis.

RESULTSSerum CPS-I and OCT levels in cirrhosis patients with hepatic encephalopathy were (143.3+/-48.5) U/L, (297.0+/-102.6) is multiplied by 10 U/L, which were lower than that in cirrhosis patients without hepatic encephalopathy (180.3+/-51.5) U/L, (351.8+/-109.0) is multiplied by 10 U/L (t = 2.53, t = 2.78, P < 0.01). Compared with healthy controls, serum CPS-I and OCT levels in cirrhosis patients with and without hepatic encephalopathy were all lower (t = 3.21, t = 4.16, t = 2.12, t = 3.15, P < 0.05). CPS-I was correlated with OCT, (r = 0.946, P < 0.05); CPS-I and OCT were negatively correlated with ALT and AST (r = -0.284, r = -0.239, r = -0.303, r = -0.322, P < 0.05). Additionally, CPS-I and OCT levels were negatively correlated with the Child-Pugh classification in Cirrhosis (F = 10.13, F = 20.28, P < 0.01).

CONCLUSIONThe serum CPS-I and COT levels were important factors affecting plasma ammonia in patients with cirrhosis and played an important role in the development of hepatic encephalopathy.

BACKGROUNDChronic heart failure (CHF) is associated with calcium transients and calcium handling proteins. Angiotensin converting enzyme (ACE) inhibitor has been demonstrated to have beneficial effect on CHF. Yet studies addressed to the relationship between ACE inhibitor and calcium transients in CHF are rare. The aim of this study was to investigate the influence of ACE inhibitor (perindopril) on the contractility and calcium transients and calcium handling proteins in ventricular myocytes from rats with experimental heart failure.

METHODSMale Wistar rats were randomized to heart failure group treated with perindopril [CHF-T, 3 mg.kg(-1).d(-1)], heart failure group without treatment (CHF-C) and sham-operated group (PS). Heart failure was induced by abdominal aortic constriction. All groups were further followed up for 12 weeks. Left ventricular myocytes were then isolated. Single cell shortening fraction and [Ca(2+)]i were simultaneously measured by laser scanning confocal microscope under the field stimulation (1.0 Hz). Reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blot were performed to evaluate the changes of mRNA and protein of Na(+)-Ca(2+) exchanger (NCX1), sarcoplasmic reticulum Ca(2+)-ATPase (SERCA2) and phospholamban (PLB).

RESULTSThe fraction of cell shortening (FS%) and [Ca(2+)]imax (nmol/L) were significantly reduced in group CHF-C compared with group PS (FS%: 7.51 +/- 1.15 vs 13.21 +/- 1.49; [Ca(2+)]i max: 330.85 +/- 50.05 vs 498.16 +/- 14.07; both P < 0.01), and restored at least partially in CHF-T group. In CHF-C group, the left ventricular mRNA of NCX1 and PLB were significantly upregulated in comparing with PS group (RNCX1/beta-Actin: 0.51 +/- 0.12 vs 0.19 +/- 0.06, P < 0.01; RPLB/beta-Actin: 0.26 +/- 0.12 vs 0.20 +/- 0.08, P < 0.05), while SERCA2 mRNA was downregulated (0.48 +/- 0.10 vs 0.80 +/- 0.11, P < 0.01). The mRNA levels of NCX1 and SERCA2 in CHF-T group were between the CHF-C and PS group, and the differences of the latter two groups were significant (all P < 0.05). In CHF-C and CHF-T groups, the protein expression of NCX1 were 1.141 +/- 0.047 and 1.074 +/- 0.081 times of that in PS group respectively (both P < 0.05), and SERCA2 protein levels were 0.803 +/- 0.100 and 0.893 +/- 0.084 times of that in PS group respectively (both P < 0.05). The protein expression of NCX1 and SERCA2 in the CHF-C and CHF-T groups is significantly different (both P < 0.05).

CONCLUSIONACE inhibitor could improve cardiac function of failing heart through directly enhancing the contractility of single cardiomyocyte, and these effects are probably mediated by its roles in preventing the deleterious changes of calcium transients and calcium handling proteins in CHF.
