Objective To investigate the possible role of eukaryotic initiation factor 6(eIF6)in the development of kidney inter-stitial tissue fibrosis in a mouse model of unilateral ureteral obstruction(UUO).Methods (1)UUO model was set up in eIF6+/-and eIF6+/+ mice.(2)HE and Masson staining were used to histologically assess the interstitial deposition of collagen in mouse kidney.Immunohistochemistry and image analysis were applied to analyze the expression of α-SMA and TGF-β1 in mouse kidney as well as eIF6 in human kidney samples.Results 10 days after unilateral ureteral obstruction,more kidney interstitial fibrosis tissues were found in eIF6+/- mice than that in eIF6+/+ mice.TGF-β1 andα-SMA were expressed more intensive in tubular epithelial cells of eIF6+/- mice than that of eIF6+/+ mice in the UUO model.Expression of eIF6 is lower in the region of fibrosis than that in non-fibrotic area.Conclusion eIF6 might be involved in the development of kidney interstitial tissue fibrosis by regulating the expres-sion of TGF-β1 .

OBJECTIVE:To investigate the influence of sevoflurane inhalation anesthesia and propofol intravenous anesthesia on hemodynamics,stress reaction and anesthesia effects of pediatric hernia surgery. METHODS:Eight-six children underwent hernia surgery in Hubei Provincial Third People's Hospital from May 2011 to Sept. 2015 were selected as subjects and divided into tri-al group and control group according to random number table,with 43 cases in each group. Trial group was given Tirofiban hydro-chloride for injection 0.4 μg/(kg·min),ivgtt,Cisatracurium besilate for injection 0.1 mg/kg+Fentanyl citrate injection 1.0 μg/kg,iv, for anesthesia induction;given 2%-3% sevoflurane inhalation for anesthesia maintenance,and additionally given fentanyl citrate 0.5 μg/kg,iv if necessary. Control group was given Propofol emulsion injection 3 mg/kg+atracurium 0.1 mg/kg+ fentanyl citrate 1.0μg/kg,iv for anesthesia induction;given micro pump injection of propofol 3 mg/(kg·h)for anesthesia maintenance,and additional-ly given fentanyl citrate 0.5 μg/kg,iv if necessary. The onset time of anesthesia,hemodynamic parameters (SBP,DBP,HR), stress reaction indexes(NE,E,R),recovery situation and the occurrence of ADR were observed in 2 groups. RESULTS:The on-set time of anesthesia in trial group was(3.82±0.45)min,significantly shorter than control group(5.13±0.74)min,with statisti-cal significance(P<0.05). Before anesthesia induction,there was no statistical significance in SBP,DBP,HR,the serum levels of NE,E and R between 2 groups(P>0.05). The levels of SBP,DBP,HR of 2 groups at incision,5 min after incision,10 min after incision were significantly higher than before anesthesia,with statistical significance(P<0.05). Above indexes of trial group at incision,5 min after incision were significantly lower than control group,with statistical significance (P<0.05). At incision, the serum levels of NE,E and R in 2 groups were increased significantly compared to before anesthesia induction,but the trial group was significantly lower than the control group,with statistical significance (P<0.05). The postoperative eye opening time, awake time and orientation recovery time of trial group were significantly shorter than control group,while the PAED score was sig-nificantly lower than control group,with statistical significance(P<0.05). The incidence of ADR in trial group(0)was significant-ly lower than control group (11.6%),with statistical significance (P<0.05). CONCLUSIONS:Sevoflurane inhalation anesthesia has less effect than propofol intravenous anesthesia on hemodynamic indexes and is helpful to relieve stress reaction and promote postoperative revival with good safety.

Objective To investigate the curative efficacy of sodium phosphocreatine combined with amin-ophylline in the treatment of postpartum hypertensive heart failure.Methods 80 patients with postpartum hyperten-sive heart failure were randomly divided into the control group and the observation group equally by random number table method,40 cases in each group.The control group was given conventional treatment,such as oxygen inhalation, diuresis by furosemide,strengthening heart by cedilanid,vascular dilation by nitroglycerin,keeping water -electrolyte balance and so on.Besides that,the observation group was given sodium phosphocreatine in combination with amin-ophylline.Then,the curative efficacy,changes of blood pressure,indices of cardiac function and adverse reactions were compared.Results The total effective rate of the observation group was 95.0%,which was higher than 80.0% of the control group(χ2 =4.1 1 ,P <0.05).After treatment,SBP,DBP,LVEDD,LVESD,LVEF in the control group and the observation group were (1 25.7 ±6.5)mmHg vs (1 20.1 ±7.2)mmHg(t =3.651 ),(88.4 ±8.9)mmHg vs (81 .4 ± 9.0)mmHg(t =3.498),(64.0 ±6.8)mm vs (61 .3 ±6.2)mm(t =2.268),(53.7 ±6.3)mm vs (51 .0 ±5.6)mm (t =2.461 ),(38.6 ±9.0)% vs (42.5 ±8.7)%(t =2.476),respectively.In comparison with the control group, SBP[(1 25.7 ±6.5)mmHg vs.(1 20.1 ±7.2)mmHg],DBP[(88.4 ±8.9)mmHg vs.(81 .4 ±9.0)mmHg], LVEDD[(64.0 ±6.8)mm vs.(60.7 ±6.2)mm],LVESD[(53.2 ±5.3)mm vs.(50.2 ±5.6)mm]were signifi-cantly reduced and LVEF[(38.6 ±9.0)% vs.(42.5 ±8.7)%]was significantly increased in the observation group (t =3.651 ,3.498,2.268,2.461 ,2.476,all P <0.05).During the treatment,there was no severe adverse reaction. Conclusion Sodium phosphocreatine combined with aminophylline is effective for postpartum hypertensive heart fail-ure,which can significantly increase curative efficacy,decrease blood pressure and improve cardiac function with less adverse reactions.

Objective To perform a meta-analysis on the association of of genotype B/C and HBV DNA conversion of negative or HBeAg clearance to lamivudine therapy.Methods Several databases (PubMed, Web of Science, Science Direct, and CNKI Database) were searched from 1966 to 2012 for all publications on the association between genotype B/C and response to LAM therapy.The articles were selected according to the protocol previously designed.Meta analysis using Revman 5 software.Results Finally, 19 RCTs were retrieved involving 3148 patients for the subsequent meta-analysis. Among them, 10 articles (n=1860) look at HBV DNA and 9 (n=1288) at HbeAg clearance.For HBV DNA conversion of negative, the overall RR (95% CI) associated with genotype B/C was 1.07(0.98-1.17). Of the nine analyzed trials, HBeAg clearance was observed in genotype B group as compared with that genotype C group, the overall RR (95% CI) was 1.27 (0.94-1.71).Conclusion Meta-analysis indicates that genotype B/C is not associated with response to LAM therapy.Further mechanism researches are required to clarify.Large-scale population studies in multicountries are also necessary to evaluate the influence of HBV genotypes in hepatitis B progression and antiviral treatment.

OBJECTIVETo explore the maintenance effects of acupoint catgut embedding at early time on gastrointestinal function in patients with craniocerebral injury.

METHODSSixty craniocerebral injury patients with 5 to 12 points of Glasgow coma scale (GCS), according to treatment order, were alternately divided into an observation group and a control group, 30 cases in each one. Patients in the control group were treated with regular treatment and nursing care. Based on this, patients in the observation group, according to different pathogenesis and symptoms presented within 24 h into hospitalization, were additionally treated with acupoint catgut embedding. The recovery time of borborygmus, time of first anal aerofluxus, time of first defecation, abdominal pressure at different time points, the occurrence rate of complications (upper gastrointestinal hemorrhage, diarrhea, vomiting), time of enteral nutrition tolerance rate reaching 30 kcal/kg x d were observed and recorded.

RESULTSThe recovery time of borborygmus, time of first anal aerofluxus, time of first defecation and time of enteral nutrition tolerance rate reaching 30 kcal/kg x d in the observation group were all earlier to those in the control group (all P<0.01). At 48 h, 4 d and 7 d into hospitalization, the abdominal pressures in the observation group were all lower than those in the control group [(11.10 +/- 1.47) mmHg vs. (13.50 +/- 1.43) mmHg, (8.40 +/- 1.25) mmHg vs. (11.90 +/- 1.56) mmHg, (6.73 +/- 0.74) mmHg vs. (10.80 +/- 1.30) mmHg, all P<0.01]. There were 8 cases with complications of gastrointestinal hemorrhage, diarrhea and vomiting in the observation group with the occurrence rate o 27% (8/30), which was lower than those in the control group (70.0% (21/30), P<0.01.

CONCLUSIONThe acupoint catgut embedding at early time in craniocerebral injury patients could improve the recovery of gastrointestinal function, reduce intolerance of enteral nutrition and occurrence rate of various complications.

Objective To investigate the clinical characteristics of systemic lupus erythematosus (SLE) and the situation of diagnosis after onset. Methods Three hundred outpatients diagnosed with SLE were investigated in the People's Hospital, the Third Hospital of Peking University, Xinjiang People's Hospital and the Affiliated Hospital from May to July 2008, including gender, age of onset, clinical manifestations and the site of first hospitalization. Results ① In the cross-sectional study, 300 SLE patients were investigated. The male-to-female ratio was 1:13. ② The most common manifestations at onset were arthritis (46.3%), rash (34.%) and fever (32.7%). Lupus nephritis was found to occur in a significantly higher frequency in male patients than female as the initial manifestation. 60.9% patients had lupus nephritis in the first year after onset. ③ 99.1% of the patients were correctly diagnosed after visiting rheumatologists. 23.7% of the SLE patients were not correctly diagnosed for more than one year after disease onset. Conclusion Arthritis, rash and fever are the most common initial clinical manifestations of SLE. Lupus nephritis is more commonly seen in male SLE patients than female at the disease onset. The diagnosis of lupus is delayed in certain proportion of patients.

Objective To analyze the clinical data, including clinical features, treatment, and prognosis,in patients with different kinds of pituitary adenomas. Methods In this retrospective study, 746 cases were included. The characteristics of general epidemiology, clinical symptoms, pathology, imaging, treatment, and prognosis were analyzed. Results Clinical features were different among various pituitary adenomas. Symptoms caused by mass effect and hormone abnormality were expresssed in varying degrees. Serum prolactin>121.28 μg/L can differentiate the prolactin adenoma from the other huge tumor causing hyperprolactinemia due to the mass effect. There is significant relationship between the size and the various types of pituitary adenomas ( P<0.01 ),also between the size and the invasive capability ( P<0.01 ). Conclusions The pituitary adenomas may have their specific epidemiological, clinical, pathological, and imaging features, due to the distinct biological behavior. It is necessary to do the diagnosis, treatment, and prognosis evaluation individually.

Objective:To investigate the protein expression of GTPBP4 in human hepatocelluar carcinoma (HCC) tissues and the influ-ence of GTPBP4 silencing by siRNA on the proliferation and cell cycle of HCC cell line Hep G2. Methods:Western blot analysis was per-formed to observe the protein expression of GTPBP4 in 24 cases of HCC tissues compared with their adjacent noncancerous liver tis-sues. Lentivirus-mediated RNA interference (RNAi) was used to silence GTPBP4 expression in Hep G2, and the infection efficiency was observed under a fluorescence microscope. The silencing effect was tested by Western blot and real-time PCR. After silencing the GT-PBP4 gene, cell proliferation was detected using CCK-8 assay, and the cell cycle was observed using flow cytometry. Results:(1) GT-PBP4 was overexpressed in 21 cases (87.5%) of HCC tissues (P<0.000 1). (2) After the lentivirus with GFP reporter infected the Hep G2 cells, 90%of the cells showed green fluorescence. LV-GTPBP4-RNAi effectively inhibited the expression of GTPBP4 at both mRNA (70%) and protein (67%) levels. (3) The proliferation ability of the LV-GTPBP4-RNAi group significantly decreased after 96 h (inhibition rate:54.51%). Flow cytometry showed that the LV-GTPBP4-RNAi group significantly increased at the G0/G1 phase, whereas the S phase de-creased and arrested at the G0/G1 phase. Conclusion:GTPBP4 overexpression in HCC tissues was associated with hepatocarcinogenesis and promoted tumor cell proliferation, but the specific molecular mechanisms remain to be investigated.
