Objective: To investigate the effect of Tanreqing injections combined with azithromycin in the treatment of children bronchial pneumonia. Methods:Totally 56 cases of pediatric bronchial pneumonia were selected in our hospital from September 2012 to September 2013 and randomly divided into the observation group and the control group with 28 cases in each. The control group was with azithromycin treatment, and the observation group was with Tanreqing injections additionally. The effect and adverse reactions of the two groups were studied and compared. Results:In the observation group, the effective rate was 92. 9%, which was significantly higher than that in the control group(P<0. 05). The hospitalization time and the symptoms disappearance time in the observation group were significantly shorter than those in the control group (P<0. 05). The adverse reactions showed no significant difference be-tween the two groups. Conclusion:Tanreqing injections in the treatment of children bronchial pneumonia is rapid, effective and safe.

Objective To observe continuous venous-venous hemofiltration (CVVH) for treatments and cares of severe acute pancreatitis(SAP). Methods From August 2004 to August 2006, 15 cases with SAP were in conventional treatment (the control group), from September 2006 to August 2010, 20 cases with SAP were nursed with CVVH(the observation group). We surveyed patients' vital signs (including body temperature, heart rate, breathing and blood pressure),mental symptoms, abdominal signs and monitored liver and kidney functions. Additionally we executed APACHE Ⅱ scores. We analyzed them retrospectively. Results The afore - mentioned indexes of two groups were significant in statistics, the observation group had lower incidence of MODS、MOF than the control group after 10 days caring. Conclusions The CVVH could correct systemic inflammatory reaction of SAP and prevent complications. Standard technical operation and intensive nursing can ensure smooth process of CVVH and decrease complications caused by CVVH.

Background The fibrosis of filtering area caused by proliferation of human Tenon fibroblasts (HTFs) is one of failure causes following glaucoma surgery.Researches revealed that hydroxycamptothecin can induce the apoptosis of HTFs,but its influence on autophagy of HTFs is unclear.Objective This study attempted to investigate whether hydroxycamptothecin can cause an alteration of autophagic activity in HTFs.Methods Human Tenon capsular tissue was obtained from 3 patients during strabismus correction surgery under the informed consent of patients and their parents for the primary culture and passaged of HTFs in DMEM containing 10％ fetal bovine serum.The generation 3 to 6 cells then were incubated with 0.0,0.5,1.0,4.0,10.0 mg/L hydroxycamptothecin for 24 hours,respectively.A cell counting kit-8 (CCK-8) was used to detect the cell viability in different treated groups.The autophagic activity of HTFs was evaluated by a Cyto-ID autophagy detection kit,and then the autophagic flux was evaluated by counting the Cyto-ID positive cells under a fluorescence microscope,and the green fluorescence intensity was determined by flow cytometry.Quantitative reverse transcriptase PCR (qRT-PCR) and Western blot analysis were employed to assay the relative expressions of autophagic-associated genes and their proteins in HTFs,including Beclin-1,autophagy related gene 5 (ATG-5) and light chain 3 (LC-3).Results The cell viability of HTFs in the 0.0,0.5,1.0,4.0 and 10.0 mg/L hydroxycamptothecin groups were (100.00 ± 6.44) ％,(91.70 ± 6.36) ％,(81.47 ± 6.00) ％,(68.43 ± 6.69) ％ and (59.97 ± 6.98) ％ respectively,showing a gradually declining trend with the increase of hydroxycamptothecin doses,with a significant difference among them (F=19.040,P＜0.001),and the viability of HTFs in the 1.0,4.0 and 10.0 mg/L hydroxycamptothecin groups were significantly decreased than the control group (P＜0.05,P＜0.01,P＜0.01).qRT-PCR analysis revealed that the relative expression levels of Beclin-1 mRNA,ATG-5 mRNA and LC-3 mRNA in 4.0 mg/L hydroxycamptothecin group were (3.225 ±0.346),(2.839 ±0.418) and (3.761±0.224) folds higher than those of the control group.The expressions of Beclin-1 and ATG-5 proteins were significantly increased in the 4.0 mg/L hydroxycamptothecin group in comparison with the control group,and the expression intensity ratio of LC-3-Ⅱ/Ⅰ was 0.965±0.159 in the hydroxycamptothecin group,which was significantly higher than 0.275 ±0.860 of the control group (P =0.003).Cyto-ID staining showed that the percentage of autophagic cells increased dramatically from (11.333±4.010) ％ to (55.000±9.013) ％ upon the exposure of HTFs to 4.0 mg/L hydroxycamptothecin (P=0.002).Flow cytometry analysis showed that the green fluorescence intensity in the 4.0 mg/L hydroxycamptothecin group was (3.037 ±0.513) fold relative to that in the control group,showing a significant difference between the two groups (P =0.003).Conclusions Hydroxycamptothecin can induce autophagy in HTFs in vitro.

OBJECTIVE Toinvestigatethedifferenceofcytotoxiceffectsofhydroxycamptothecin(HCPT)onhuman lungcancercelsA549andhumanembryolungfibroblastcelsMRC-5.METHODS A549celsandMRC-5celswere treated with HCPT 20-200 μmol·L-1 for 24,48 and 72 h,or pulse treated with HCPT 50-400 μmol·L-1 for 24 h along with 5 d release.cellsurvival was detected by MTT assay.Morphological changes for both types of cells were observed under an inverted phase-contrast microscope.cellcycle and apoptosis in both cells treated with HCPT 50 μmol·L-1 for 48 h weredeterminedbyflowcytometry.RESULTS HCPT20-200μmol·L-1inhibitedthesurvivalofbothcelsinaconcen-tration-dependent manner and more cytotoxicity was observed in A549 cells for 48 h.The concentration-effect correlation coefficient(r)of HCPT in A549 and MRC-5 cells for 48 h was 0.898 (P=0.015)and 0.996 (P=2.56E-5)respectively. The inhibition rates were significantly different between A549 and MRC-5 cells with treatment of HCPT 20,50,80,1 00, 1 60 and 200 μmol·L-1 for 48 h (P<0.05).The IC50 of HCPT on A549 and MRC-5 cells was (24.00 ±0.69)μmol·L-1 and (1 23.63 ±3.89)μmol·L-1 respectively,indicating that A549 cells were 5-fold more sensitive to HCPT than MRC-5 cells at 48 h.After exposure to HCPT 50 μmol·L-1 for 48 h,some A549 cells were rounded up and shrank dramatical y, and some cells underwent membrane blebbing or lysing while MRC-5 cells had no obvious changes.cellcycle and apop-tosis analysis showed that A549 cells were arrested at both S and G2/M phases and apoptosis occurred but MRC-5 cells were just arrested at S phase.In the recovery growth curve,the growth of A549 cells was inhibited to a larger extent than MRC-5 cells and the growth retardation stil existed for 24 h in both cells.The survival of MRC-5 cells was faster than that ofA549cels,althoughtherewasnocompleterecoveryineithercel.CONCLUSION A549celsaremoresensitiveto HCPT than MRC-5 cells due to the fact that HCPT induces cellcycle arrest at both S and G2/M phases and apoptosis in A549 cells,but only triggers S phase arrest in the MRC-5 cells.

Objective · To investigate the status of depression and anxiety in patients with recurrent spontaneous abortion (RSA) and the possible influence factors and to provide theoretical support for further psychological intervention. Methods · RSA patients and women with no history of RSA were invited to complete a questionnaire, including basic information, Self-Rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS). All data were analyzed by SPSS. Results · Of all 1064 cases included in this study, 725 were RSA cases, 217 cases with one spontaneous abortion and 122 in control group with no history of spontaneous abortion. Our results showed that both RSA patients and patients with one spontaneous abortion have significantly higher SDS and SAS scores than control group. Furthermore, non-pregnant RSA patients with lower education level, lower household income and 3-5 years of marriage have significantly higher levels of depression and anxiety. Patients with multiple miscarriages (≥4), history of induced abortion and no live birth, score significantly higher in SDS. Conclusion · Whether pregnant or not, RSA patients are much easier to become depressive and anxious, which may be associated with education level, household income, length of marriage, numbers of pregnancy losses and previous live birth. Women with one spontaneous abortion also show a significant higher tendency of depression and anxiety. These patients should be given proper psychological intervention if necessary.

Objective·To study the hemodynamic parameters of uterine at midluteal phase in patients with early recurrent spontaneous abortion (ERSA) and the effect of aspirin on them. Methods·Transvaginal color Doppler ultrasonography was used to measure the parameters of uterine blood flow and the endometrial thickness at midluteal phase of 271 women with ERSA (ERSA group) and 66 women without a history of recurrent spontaneous abortion (control group). Then ERSA group were administered with aspirin 50 mg/d orally for 2 months and other individualized treatment, and the effect of aspirin on parameters of uterine blood flow and the early pregnancy outcome of them were observed. Results·At midluteal phase, the endometrium was significantly thinner in ERSA group than that in control group. Pulsatility index (PI) of endometrial blood flow and mean PI (mPI), mean resistance index (mRI), and mean systolic/diastolic ratio value (mS/D) of uterine arteries were statistically significantly higher in ERSA group in comparison to control group (P<0.05). Following aspirin treatment, resistance to uterine blood flow reduced significantly in ERSA group (P=0.000), and the endometrial thickness increased in the patients with endometrial thickness less than 7 mm (P=0.000). Only 163 ERSA patients were re-examined by transvaginal color Doppler ultrasonography after aspirin treatment, among whom 136 women was pregnant after individualized treatment. Among these pregnant patients, 97 cases were pregnant for more than or equal to 12 weeks, while 10 cases aborted during the first 12 weeks, and the early pregnancy outcomes of the other 29 cases were still unclear. Conclusion·In comparison with normal fertile women, ERSA patients have significantly higher resistance to uterine blood flow and thinner endometrium. Aspirin can improve uterine blood perfusion, which improves early pregnancy outcome.
