OBJECTIVETo investigate the result of hip arthroplasty for failed internal fixation of femoral neck fractures.

METHODSFrom June 2007 to January 2014, 29 cases who underwent hip arthroplasty for failed of internal fixation of femoral neck fractures were reviewed. There were 12 males and 17 females. The mean age was 60.3 years (ranged 43 to 83 years) at the time of the fracture. Left hip was in 16 cases, right hip was in 13 cases. The average interval from fracture to arthroplasty was 23.3 months (ranged, 3 to 48 months).

RESULTSAll of 29 cases were performed total hip arthroplasty. There were 20 cases of cementless cup,7 cases of cementless cup with bone graft, 2 cases of cemented cup with bone graft; 13 cases of cementless stem, 16 cases of cemented stem. There were no complications occurred such as intraoperative fracture of the greater trochanter. The average operative time was (115 ± 38) minutes,the mean intraoperative blood loss was (420 ± 175) ml, the average postoperative drainage volume (240 ± 119) ml, intraoperative blood transfusion was (200 ± 220) ml, intraoperative fluid volume was (2,200 ± 400) ml, the average postoperative blood transfusion was (300 ± 200) ml. There was 1 case get postoperative dislocation. All patients were followed up for 14.7 months in average (ranged, 5 to 24 months). There was no revision for mechanical failure. Harris Hip Score significantly was improved from 51.1 ± 7.5 before the conversion to 88.5 ± 6.4 points at the final follow-up.

CONCLUSIONThe effect of the hip replacement for patients with failed internal fixation of femoral neck fractures was confirmed. This method can shorten the time on the bed and reduce the complications. It benefits the patients earlier functional recovery, but it must control operation indication. The long term efficacy is necessary to further observation.

Objective To construct a eukaryotic vector which contains avian H5N1 influenza virus hemagglutinin (HA) antigen and the cholera toxin B subunit (CTB) and to investigate its expression in COS7 cells,and the ability to induce specific immune responses in vivo in different periods.Methods After cloned by polymerase chain reaction (PCR),CTB and HA genes were digested with BamH Ⅰ and connected into CTB-HA gene with T4 ligase.The connected gene was referred to as CH.After double digestion,CH gene was inserted into a eukaryotic recombinant plasmid pCI-neo.The pCI-CH plasmid was then transfected into COS7 cells.Western blot was used to detect the expression of HA antigen.After New Zealand white rabbits were immunized,the titer of HA antigen-specific antibody in serum and its specificity with other strains such as H1N1,H9N1,H3N2 and influenza B virus were determined by indirect enzyme-linked immunosorbent assay.Results The pCI-CH vector (DNA vaccine) was successfully constructed,which could be efficiently expressed in COS7 cells and induce specific antibodies against pCI-CH in rabbits.Cross reactions indicated that DNA vaccine pCI-CH specific antisera could not only react with H5N1 strain (P/N＞2.1),but also H1N1,H9N1 and H3N2 strains,but did not cross react with influenza B virus.Conclusion The newly constructed avian H5N1 influenza virus nucleic acid vaccine has good immunogenicity.

Objective To improve the recognition of nervous system symptoms of inborn errors.Methods Five patients with organic acidemias were screened by urine organic acid analysis(gas chromotography-mass spectrometry,GC/MS),3 cases of methylmalolic acidemias(MMA) and 2 cases of propionic acidemias(PA) were confirmed.They were treated with special diet and medicine after diagnosis.Result The improvement of mental development was observed after treatment.Conclusions Most of organic acidemias involve nervous systems,causing non-specific symptoms of nervous system as lethergy,seizures,mental retardation.Inborn errors of metabolism shall be kept in mind when causes of the symtoms of acidosis,seisures,mental retardation and lethergy are investigated.GC/MS is a very important method in diagnosis of organic acidemias.Early diagnosis and early treatment can improve the mental prognosis.

Objective To undemtand the rhythm of urinary iodine level of children aged 8-10 in Chongqing city.Methods In April 2008,using the stratified random sampling method,we sampled 60 children aged 8-10 in a lodging primary school in Chongqing(20 per age group,half male and half female),the urine samples were collected in the morning and at 10:00,12:30,16:00,iodine in urine was detected by method of Ce and arsenic catalytic speetrophotometry(WS/T 107-2006).The difference of the urinary iodine level was compared by age,sex and time of day.Results The median urinary iodine of 60 children was 265.07μg/L on the overall.Irrespective of the stratification factors,excluding morning urinary iodine(366.75μg/L)and urinary iodine at 10:00(338.30 μg/L),the urinary iodine between 12:30(235.15μg/L)and 16:00(251.50μg/L)was not significant(all P>0.05),statistically significant differences(all P<0.05)were found between any two.The urinary iodine of 8-year-old group at different times of the day was significantly different(all P<0.05),except between morning urinary iodine (298.90 μg/L)and at 10:00,16:00(279.00,286.59 μg/L),between urinary iodine at 10:00 and 16:00(all P>0.05).The 9-year-old group's urinary iodine were not significantly different between morning urine(366.15μg/L)and 10:00(368.10 μg/L),and between 12:30(244.00 μg/L)and 16:00(186.30 μg/L,all P>0.05),significant differences were faund at other times of the day(all P<0.05).The 10-year-old group of urinary iodine changed very little before 12:30 (382.85,449.60,337.00 μg/L, all P > 0.05 ), followed by rapid decline to 16: 00 (269.35 μg/L), and compared with the morning urine and 10:00, there was significant difference(all P < 0.05).Regardless boys or girls, the urinary iodine at different times qf the day was significantly different (all P < 0.05),except between morning urinary iodine(337.32,309.28 μg/L) and at 10:00(316.15,288.27 μg/L), between urinary iodine at 12:30(251.18,211.45 μg/L) and 16:00(235.02,211.45 μg/L, all P > 0.05). Conclusions The change of urinary iodine level in children aged 8 - 10 was not obvious before noon, changes can be seen in the afternoon.Urinary iodine level before 10:00 is indicative.

OBJECTIVETo establish a new method for simultaneous determination of shanzhiside methyl ester, chlorogenic acid, 8-O-acetyl shanzhiside methylester, forsythiaside B, rutin, acteoside and galuteolin in Lamiophlomis rotata.

METHODSeparation was performed on a Welchrom-C18 chromatographic column with acetonitrile-0.1% orthophosphoric acid as mobile phasewith gradient elution. The flow rate was 1.0 mL x min(-1). The column temperature was 30 degrees C, and the detection wavelength was set at 238 nm, 330 nm and 350 nm.

RESULTThe seven compounds were well separated with good linear correlations. The mean recoveries of seven compounds were 96.47%-102.2% (RSD 0.70%-2.2%).

CONCLUSIONThere were good correlations among the seven compounds in the samples of aerial parts. The mean sum of shanzhiside methyl ester and 8-O-acetyl shanzhiside methylester in samples of aerial parts is 1.44%. The aerial parts have more kinds of composition and with higher content than that of underground parts in L. rotata, which was reasonable for the resonable use of the aerial part as medicinal part. The method was simple, repeatable and stable, which could be used for identification and quality evaluation of L. rotata.

BACKGROUND: Early reperfusion can effectively treat acute myocardial infarction (AMI) and reduce the mortality significantly. This study aimed to compare the role of plasma microRNA-1 (miR-1) and cardiac troponin T (cTnT) in early diagnosis of AMI patients. METHODS: From May 2011 to May 2012, plasma samples were collected from 56 AMI patients and 28 non-AMI controls. The expression of plasma miR-1 was measured by quantitative reverse transcription-polymerase chain reaction (qRT-PCR), and the level of plasma cTnT was measured using electrochemiluminescence-based methods on an Elecsys 2010 Immunoassay Analyzer. SPSS 16.0 was used for the statistical analysis of the results. Data were expressed as mean±standard deviation unless otherwise described. The differences about clinical characteristics between the AMI patients and controls were tested using Student'st test or Fisher's exact test. The Mann-WhitneyU test was conducted to compare the expression of microRNAs between the AMI patients and controls. MicroRNAs expression between different intervals of the AMI patients was compared using Wilcoxon's signed-rank test. The receiver operating characteristic (ROC) curve was established to discriminate the AMI patients from the controls. RESULTS: In the present study, the expression of plasma miR-1 was significantly increased in the AMI patients compared with the healthy controls (P<0.01). The plasma miR-1 in the AMI patients decreased to the normal level at 14 days (P>0.05). The expression of plasma miR-1 was not related to the clinical characteristics of the study population (P>0.05). ROC curve analyses demonstrated that miR-1 was specific and sensitive for the early diagnosis of AMI, but not superior to cTnT. CONCLUSION: Plasma miR-1 could be used in the early diagnosis of AMI, but it is similar to cTnT.

BACKGROUND:To invent a novel cardiopulmonary resuscitation (CPR) time point recorder to synchronously and automatically record the time and to identify its effectiveness in humans. METHODS:A CPR time point recorder was invented after the doctors were familiar with the traditional Utstein recovery registration mode and mastered the registration time points required. The progress of CPR was simulated. The standard and correct times were recorded, and the doctors performing the recovery collected the data about the times using our CPR time point recorder or the memory registration mode. RESULTS:The deviation times were 21.4±24.7 seconds for the memory group and 3.57±4.58 seconds for CPR time point recorder group. The deviation of times increased significantly depending on the increase of the operation items in the memory group. A similar phenomenon was found in the timer group but with a smaller difference (P<0.01). CONCLUSION: A CPR time point recorder could reduce the deviation of operate-time, especially after a long-time operation, and for procedures with more operating items, compared with the memory mode. It was a more advantageous and accurate method for the Utstein registration.

OBJECTIVE: The aim of the study was to compare transcatheter arterial chemoembolization (TACE) plus ¹³¹I-labelled metuximab with TACE alone for hepatocellular carcinoma (HCC). MATERIALS AND METHODS: A comprehensive search was conducted in PubMed, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Chinese BioMedical Literature Database with published date from the earliest to February 29th, 2016. No language restrictions were applied, but only prospective randomized controlled trials (RCTs) or non-RCTs were eligible for a full-text review. The primary outcome was the overall survival (OS) and effective rate (the rate of partial atrophy or complete clearance of the tumor lesion). The odds ratios (ORs) were combined using either the fixed-effects model or random-effects model. RESULTS: Eight trials (3 RCTs and 5 non-RCTs) were included, involving a total of 1121 patients. Patients receiving combined therapy of TACE plus ¹³¹I-labelled metuximab showed significant improvement in effective rate {OR = 4.00, (95% confidence interval [CI]: 2.40–6.66), p < 0.001}, 1-year OS (OR = 2.03 [95% CI: 1.55–2.67], p < 0.001) and 2-year OS (OR = 2.57 [95% CI: 1.41–4.66], p = 0.002]. CONCLUSION: TACE plus ¹³¹I-labelled metuximab is more beneficial for treating advanced HCCs than TACE alone in terms of tumor response and OS. Large, multi-center, and blinded randomized trials are required to confirm these findings.
