Objective To investigate the management of pseudomyxoma peritonei originated in the appendix.Methods The clinical data of 51 patients with pseudomyxoma peritonei originated in the appendix who were admitted to the Beijing Hospital from 1970 to 2010 were retrospectively analyzed.The results of operation,reoperation,adjuvant treatment and follow-up were analyzed.The time from pseudomyxoma peritonei recurrence to the reoperation between patients who did or did not receive chemotherapy was compared by two tailed t test.Results Of the 51 patients,48 received operation,and the operation time was (135 ± 72 )minutes.Tumor recurrence was observed in 34 patients,and 16 of them received cytoreduction procedure,and 33 cytoreduction procedures were performed in total.The median time of follow-up was 49.7 months (range,3-132 months).The disease-specific survival was observed in 25 patients and disease-free survival in 16 patients.Four patients died of tumor recurrence or progression.The results of postoperative pathological examination confirmed that 19 patients were with benign disseminated peritoneal adenomucinosis (DPAM),26 were with malignant peritoneal mucinous carcinomatosis (PMCA) and 6 were with intermediate subtype (PMCA-1).The 3-,5- and 10-year survival rates were 75％ (38/51),55％ (28/51) and 22％ ( 11/51 ),respectively.The survival time and reoperation time interval for patients who received postoperative chemotherapy were ( 21 ± 4) months and ( 10 ± 6 ) months,which were longer than (19 ±7 )months and (7 ±4)months of those who did not receive postoperative chemotherapy (t =1.027,0.361,P ＞ 0.05).The median survival time of patients with benign DPAM,PMCA-1 and malignant PMCA were 96,63,23 months,respectively.The tumor recurrence interval for patients with benign DPAM and those with malignant PMCA were ( 15 ± 5 ) months and (7 ± 4) months,with significant difference ( t =2.193,P ＜ 0.05 ).Conclusions An active cytoreduction surgery is feasible for patients with pseudomyxoma peritonei originated in the appendix in improving survival.Repeated cytoreduction is a treatment of strategy to prolong the recurrence time and improve the prognosis of selected patients.

Objective:To investigate the application of Xiyanping injections ( XYP) in the bone surgery department inpatients in a certain hospital to provide reference for the clinical rational medication. Methods:A retrospective investigation was adopted to randomly survey 180 hospitalized medical recorders with XYP from a certain hospital in 2013. The usage, dosage and medication purpose of XYP were analyzed. Results:The reasonable rate of usage and dosage of XYP was 97. 2%. Among the surgical patients, 82. 8% were giv-en XYP, and among them, 97. 3% was accordance with the medication purpose. Among the nonsurgical patients, 17. 2% were given XYP, and among them, 71. 0% was accordance with the medication purpose. The alone-use rate was 60. 0% and the rate of combina-tion with antibacterials was 40. 0%. The longest treatment course was 20d, the shortest one was 1 d, and the mean value was (7. 7 ± 5. 3) d. Conclusion:Irrational use of XYP exists in clinics, and the use should be strengthened and regulated.

OBJECTIVETo explore clinical significance of rotational axis of distal femur on Chinese adults in total knee arthroplasty (TKA).

METHODSThere were 86 Chinese adults (106 normal knees) including 47 males (53 knees) and 39 females (53 knees), 54 knees were on left and 52 on right. The CT scan was employed in the distal femur. The scan direction was aligned to be on the plane perpendicular to the mechanical axis of the femoral. The CT images of cross sections across lateral and medial femoral epicondyle were moved to personal computer,lateral angle between anterior posterior line (APL) and surgical transepicondylar axis (STEA) (ATA),lateral angle between posterior condylar line (PCL) and APL (APA), angle between perpendicularity of APL and PCL (A-PA), posterior condylar angle (PCA), condylar twist angle (CTA), angle between clinical transepicondylar axis (CTEA) and STEA (CSA) were measured. These values were divided into different groups according to gender and side, the values of CTA, PCA, A-PA, angle PT (varus of tibia plateau), constant 3, ATA, APA and constant 90° were compared by statistically. A-PA and PCA, and CTA were analysed statistically with the liner regression, the relationship among CTEA, STEA ,PCL, APL and PLP were performed to assess by liner regression.

RESULTSATA was (89.79 ± 1.22)°, APA was (84.84 ± 1.83)°, A-PA was (5.16 ± 1.83)°, PCA was (4.80 ± 1.23)°, CTA was (8.23 ± 1.40), CSA was (3.45 ± 0.68)°. All the parameters had no differences on sex and side,but CSA had difference on male and female. There was no difference among angle PT, PCA, A-PA. There was significant difference in CAT, constant 30 and angle PT, PCA,A-PA. There was no difference between ATA and constant 90°, but there was difference between APA and constant 90°. There was relativity between PCA and CTA, and also PCA and A-PA, CTA and A-PA. There was significant relativity between STEA and CTEA, between STEA and APL, between STEA and PCL, and also between APLP, APL and PCL, but there was no significant relativity between PCL and CTEA.

CONCLUSIONTKA for Chinese, the section of femoral posterior condyle should be external 5° to obtain the optimum rotational orientation. The property is different entirely between STEA and CTEA, the rotational alignment is not performed according to parallel to the CTEA in distal femur. Among STEA, APL, PCL, the STEA is the most reliable mark ofrotational alignment of the distal femur, and the PCL is the less reliable mark.

The endophytic bacteria of the mangroves were studied in this paper. The results show that there are 1.728 (0. 195 -4.225)?104cfu/g (fw) bacterial endophytes in the variety of mangroves, the most population of the endophytic bacteria was found in Rhizophora stylosa, the figure was4. 225?104cfu/g (fw) , the next was Bruguiera gymnorrhiza, Aegiceras corniculatum, Kandelia candel and Avicennia marina. In parts of the mangroves, the contents of the bacteria in stem was the most, the figure was 1. 649?10 cfu/g (fw) , then the root and the leaf. Of the bacteria, about 43. 53% strains expressed the antagonism against the growth of the plant pathogens, such as Fusarium oxyspontm f. sp. cubense , Colletotrichum sp. and Rahtonia solanaceance etc. and these bacteria were identified as Bacillus sp. . The results also showed that 9 of the 13 strains (69. 23% ) could promote the growth of the tomato, while 4 strains (30. 77% ) restrained the tomato's growth.

Objective To investigate the effect of arginase (Arg) inhibitor N-ω-Hydroxy-L norArginine (nor-NOHA) on high glucose cultured rhesus macaque retinal vascular endothelial cell line (RF/6A) in vitro.Methods The RF/6A cells were divided into the following 4 groups:normal control group (5.0 mmol/L of glucose,group A),high glucose group (25.0 mmol/L,group B),high glucose with 125 mg/L nor-NOHA group (group C),and high glucose with 1％ DMSO group (group D).The proliferation,migration ability and angiogenic ability of RF/6A cells were measured by Methyl thiazolyl tetrazolium (MTT),transwell chamber and tube assay respectively.The express of Arg Ⅰ,eNOS,iNOS mRNA of RF/6A cells were measured by real-time polymerase chain reaction (RT-PCR),Enzyme-linked immuno sorbent assay (ELISA) was used to detect the expression of NO and interleukine (IL)-1b of RF/6A cells.Results The proliferation,migration,and tube formation ability of group A (t=2.367,5.633,7.045;P＜0.05) and group C (t=5.260,6.952,8.875;P＜0.05)were significantly higher than group B.RT-PCR results showed the Arg Ⅰ and iNOS expression in group B was higher than that in group A (t=6.836,3.342;P＜0.05) and group C (t=4.904,7.192;P＜0.05).The eNOS expression in group B was lower than that in group A and group C (t=4.165,6.594;P＜0.05).ELISA results showed NO expression in group B was lower than that in group A and group C (t=4.925,5.368;P＜0.05).IL-1b expression in group B was higher than that in group A and group C (t=5.032,7.792;P＜0.05).Conclusions Nor-NOHA has a protective effect on cultured RF/6A cells in vitro and can enhance its proliferation,migration and tube formation.The mechanism may be inhibiting the oxidative stress by balancing the expression of Arg/NOS.

Objective To investigate the effects of exosomes from cultured human retinal pigment epithelium (ARPE-19) cells affected by oxidative stress on the proliferation and expression of vascular endothelial growth factor-A (VEGF-A) and Akt of ARPE-19 cells. Methods Culture ARPE-19 cells. The concentration of 2.5μmol/L rotenone was selected to simulate oxidative stress and isolated ARPE-19-exosome. Exosomes were isolated by ExoQuick exosome precipitation solution. Transmission electron microscopy was used to identify the morphology of exosomes. Western blot was used to detect exosomes’ surface-specific maker protein CD63. ARPE-19 cells affected by oxidative stress were cultured with exosome as experimental group, normal ARPE-19 cells were cultured with exosome as control group. The cell proliferation was examined by methyl thiazolyl tetrazolium assay. Western blot and immunofluorescence assay were used to detect the expression levels of VEGF-A and Akt protein. Real-time quantitative polymerase chain reaction (RT-PCR) was used to detect the levels of VEGF-A mRNA and Akt mRNA. Results The diameter of normal ARPE-19-exosomes ranged from 50 to 150 nm. The isolated exosomes expressed CD63. AREP-19 cells were cultured with ARPE-19 (affected by rotenone)-exosome, the cell viability in experimental group was significantly reduced than in the control group. Green fluorescence was observed in the cytoplasm under fluorescence microscope. Compared with the control group, VEGF-A was up-regulated expressed and Akt was down-regulated expressed. Western blot results showed that, VEGF-A protein expression in the experimental group were higher than the control group. Akt protein expression in the experimental group were less than the control group. The difference was statically significant (t=3.822, 6.527;P<0.05). RT-PCR results showed that VEGF-A mRNA expression levels was higher in the experimental group than the control group. Akt mRNA expression levels was lower in the experimental group than the control group. The difference was statically significant (t=8.805,?7.823;P<0.05). Conclusions Exosomes from ARPE-19 cells affected by oxidative stress inhibit the proliferation of normal ARPE-19 cells, increase the expression of VEGF-A and reduce the expression of Akt.

Background The situation of zonule is very important for determining the cataract surgery.Ultrasound biomicroscopy (UBM) is an important method to observe the situation of zonule before cataract surgery.Objective This study was to evaluate the accuracy and clinical significance of observing the zonule of cataract patients by UBM.Methods A series cases-observational study was performed.One hundred and thirty eyes of 130 cataract patients who were to receive extracapsular cataract enucleation were enrolled in Tianjin Eye Hospital from January to June 2015,including 59 eyes with cataract associated with primary angle-closure glaucoma (PACG) and 71 eyes with traumatic cataract.UBM examination was carried out before surgery,and the abnormalities of zonule were recorded and compared between UBM and surgery findings.This study was approved by the Ethic Committee of Tianjin Eye Hospital and informed consent was obtained from all subjects.Results A large space between lens and cilliary was exhibited and the echo of zonule was clear on the UBM image in the eyes with traumatic cataract.The typical anatomic findings of the anterior eye segment were displayed,and lens equator came into contact with cilliary on the UBM image,and the echo of zonule was blurry in the eyes with cataract associated with PACG.The eye number of abnormal zonule was consistent between UBM and surgery findings (Kappa=O.952),and no significant difference in the eye number of abnormal zonule between UBM and surgery findings (P =0.250).In 75 zonule abnormal eyes diagnosed by both UBM and surgery findings,zonule abnormal range could not be compared in 1 eye (1/130,0.77％),and exactly consistent in 8 eyes (8/130,6.15％) between the two methods.The difference of zonule abnormal range between the two methods was 1 clock in 35 eyes (35/130,26.92％),and 2 clock in 27 eyes (27/130,20.77％),3 clock in 4 eyes (4/130,3.08％).In 74 zonule abnormal eyes,the mean difference of zonule abnormal meridian between the two methods was (1.36 ± 1.29) clock,an those in 28 traumatic cataract eyes and 36 cataract with PACG eyes were (1.14±1.10) clock and (1.64-± 1.48) clock,respectively.Conclusions UBM is able to observe zonule accurately,the observation effectiveness of UBM for traumatic cataract is better than that of cataract combined with PACG.These results are of clinical valueable for surgical strategy of cataract and prediction of surgical complications.
