Objective To compare the cervical intervertebral movements produced by posteroanterior cervical mobilization and posteroanterior cervical mobilization combined with cervical traction by using the radiographic measurement.Methods The study recruited 12 normal volunteers (6 men,6 women),aged 18 to 25 years (22.9±4.7 years),heighted (164± 7)cm and weighed (54.7 ± 7.6)kg.All the subjects were administered with posteroanterior cervical mobilization followed by posteroanterior cervical mobilization while having cervical traction,or vice versa,with an interval of 2 days in between.The X-ray films were collected before and after the treatment,using 4 static cervical lateral views.The axial displacement of posterior and anterior intervertebral separation (IVS),and the shear displacement of vertebral body as well as the rotation and displacement rate of the motion segments in the sagittal plane before and after the treatment were measured on the radiographic images and compared.Results It was shown that the posteroanterior cervical mobilization produced greater C2-C7 rotation range of motion in the sagittal plane,as compared to that by the posteroanterior mobilization while having cervical traction (P ＜ 0.05).The posteroanterior mobilization produced a significantly greater increase of anterior IVS of the C5 segment and the summation of C2-C7 posterior IVS than those by posteroanterior mobilization while having cervical traction (P ＜ 0.05).However,the posterior IVS and the posterior zygapophysial joints separation of C2-C7 produced by the posteroanterior mobilization during traction were more prominent (P ＜ 0.05).There was no statistical difference between anteroposterior displacements of the vertebral body produced by the two interventions.Comparing with the baseline,the posteroanterior mobilization caused posterior movement of the vertebral bodies of C5 to C2,while the posteroanterior cervical mobilization during traction produced posterior movement of C5 to C2 vertebral bodies and anterior movement of C6 body.Conclusion The cervical posteroanterior mobilization significantly increased the lordosis from C3 to C7,and reduced posterior IVS and zygapophysial joints separation.However,the posteroanterior mobilization during traction changed the intervertebral movements.

Objective To study the intervention effect of montelukast on thymus and activation-regulated chemokine(TARC) in the children with asthma.Methods 100 children with asthma were randomly divided into montelukast (LTRA) group ( n = 50) and budesonide (BUD) group ( n = 50), the LTRA group was treated with montelukast, the BUD group was treated with budesonide,50 children without asthma as control group were inhaled NS.Before and after 7 days treatment,the asthma symptoms, FEV1,concentration of TARC were measured.Results Before treatment,the concentration of TARC in asthma group was significantly higher than control group (P < 0.05 ).After treatment, the concentration of TARC in BUD group and LTRA group was significandy decreased( P < 0.05 ), but the difference between these two groups was not significantl( P > 0.05 ), the concentration of TARC in control group was not significantly decreased(P > 0.05 ) ;the symptoms were better after treatment in BUD group and LTRA group,(P <0,05) ,and the pulmonary function was significantly improved after treatment in BUD group and LTRA group ( P < 0.05 ).Conclusion TARC was the important factor in children asthma.Montelukast could block the production of TARC ,and was more convenient and safe for children asthma.

Objective To evaluate the extremity function of patients with intracerebral hemorrhage (ICH)using short-latency somatosensory evoked potentials (SEPs) and a modified intracerebral hemorrhage (MICH) scale.Methods On admission, SEP was applied in the examination of 61 patients with ICH. P40 latency and the amplitude of posterior tibial nerve potentials in both the healthy and affected extremities were measured. Abnormalities were classified based on the margin of lower extremity SEP latency and the main waveform changes. MICH was measured simultaneously to prepare a prognosis. The modified Rankin scale (MRS) score was assessed 3 months after the attack as well.Results Compared with the healthy side, there were significant differences in posterior tibial nerve P40 latency and amplitude on the affected side among patients with ICH. P40 latency and MRS scores on the affected side 3 months after the attack were positively correlated. On the unaffected side, P40 amplitude and the MRS score 3 months after the attack were negatively correlated. The MICH score on admission and the MRS score 3 months after the attack were positively correlated. Based on MRS scores (MRS≥4 indicating a poor prognosis), the predictive sensitivities for a poor prognosis of SEP and the MICH scale in patients with ICH were 80.77% and 84.61% respectively, while the specificities were 62.68% and 88.57% respectively, and the accordance rates were 70.5% and 86.9% respectively. Conclusions SEP and the MICH scale are closely correlated with the prognosis for extremity function in patients with ICH.The combination of SEP with the MICH scale might be helpful in predicting the prognosis of the patients with ICH.

Objective To explore the efficacy and adverse reaction of nedaplatin (NDP)+gemcitabine (GEM)and cisplatin (DDP)+GEM for advanced lung squamous cell carcinoma.Methods A total of 1 01 cases advanced untreated patients from September 201 2 to December 201 3 were randomly divided into 2 groups using random number table method:69 patients in the observation group accepted NDP+GEM treatment and 32 patients in the control group received DDP +GEMtreatment.The objective response rate (RR),disease control rate (DCR ) and progression-free survival (PFS ) and adverse reaction were collected and evaluated. Results RR was 28.6%(1 8/63)in the observation group and 1 5.6%(5/32)in the control group,DCR was 81 .0%(51/63)in the observation group and 68.8%(22/32)in the control group (χ2 =1 .36,P=0.24;χ2 =1 .67,P=0.20).The median PFS was 4.52 months and 4.01 months in the observation group and control group (χ2 =0.09,P=0.73).The major adverse reaction was myelosuppression in both groups (33.3% vs.37.5%,χ2 =0.1 7,P=0.68).The incidence ofⅢ-Ⅳ grade nausea and vomiting was lower in the observation group, compared with the control group (1 4.5%vs.56.3%,χ2 =1 9.02,P=0.05).Conclusion NDP combined with GEM in advanced lung squamous cell carcinoma of the first-line treatment has equivalent efficacy to DDP+GEM, with lower incidence of adverse reaction,which is worthy of further dissemination of research.

Objective:The aims of this study were to compare the efficacy between salvage liver transplantation (sLT) and rehepatectomy (RR) basing on the propensity score matching (PSM), and to explore the prognositc factors of patients with recurrent hepatocellular carcinoma (HCC).Methods:124 patients with intrahepatic recurrence after hepatectomy in our center from January 2012 to August 2018 were divided into sLT group( n=46) and RR group( n=78). 34 patients were selected for data analysis base on 1∶1 propensity score matching (PSM). The advantages and disadvantages of the two surgical methods and the prognostic factors of the patients were discussed by comparing the basic clinical data, OS and DFS of the two groups before and after matching. Results:Before matching, the pre-operative serum total bilirubin, the occurrence of multiple tumors, the proportion of preoperative TACE and the proportion of patients within Milan criteria of the sLT group were higher than those of the RR group, and the maximum tumor diameter of the sLT group was shorter than that of the RR group ( P<0.05); the time of operation, the amount of intra-operative blood loss, the positive of MVI and the proportion of postoperative Clavien grade Ⅲ and above of RR group were higher than those of RR group ( P<0.05). After matching, the operation time, intra-operative blood loss and the proportion of postoperative complications of sLT group were higher than those of RR group; there was nosignificant difference between 1-, 3- and 5- years OS of sLT group and RR group( P>0.05), the 1-, 3- and 5-years DFS of sLT group were better than those of RR group( P<0.05); AFP≥100 μg/L was the independent risk factor of OS, and the type of operation and AFP≥100 μg/L were independent risk factors of DFS. Conclusions:The pre-operative condition of sLT group was more severe, and the operation time, intra-operative blood loss and post-operative severe complication rate of sLT group were higher than those of RR group, and the DFS time of sLT group was longer than that of RR group, but there was no significant difference in OS between the two groups.

Objective To develop and validate a simple and reliable HPLC method for the analysis of L-carnitine in human seminal plasma and to investigate its clinical significance as a potentially useful index of infertile.Methods After proteins in seminal plasma are precipitated with acetonitrile,L-carnitine in seminal plasma was derivatized to form its ester.HPLC separation of the sample solution was performed on a Lichrospher SiO_2 column and detected by ultraviolet absorbance at 260 nm.A mobile phase composed of acetonitrile-citrie acid buffer(containing 12 mmol/L triethanolamine,pH 5.0)was found to be the most suitable for this separation at a flow rate of 1.2 ml/min and enabled the baseline separation of the L-carnitine from interferences with isocratic elution.The L-carnitine levels in seminal plasma were studied in both 87 patients with infertility and 30 control subjects.Results Under the chromatographic conditions described, the L-carnitine derivative had a retention time of approximately 13 min.Good separation and detectability of L-carnitine in human seminal plasma sample were obtained.The method proved to be linear in the range of L-carnitine from 0 ?mol/L to 1000 ?mol/L.The relative standard deviations of within-and between-assay for L-carnitine analysis were 1.23% and 1.36%,respectively.The recoveries were 91.6% -96.5% for the human seminal plasma samples.L-carnitine concentrations in the populations were(392.7?107.2)?mol/L in the fertile group(n=30),(270.0?83.9)?mol/L in asthenozoospermia group(n=29),(187.9? 43.9)?mol/L in oligozoospermia group(n=19)and(175.7?67.1)?mol/L in oligoasthenozoospermia group(n=39).The large difference(P0.05).Conclusion The determination of L-carnitine level in seminal plasma may prove useful as a potentially biochemical marker of fertility and this is a useful guidance for the clinic therapy and the mechanismic study on the male reproduction.

Objective To investigate the MR features of pituitary abscess.Methods The MR features of 14 cases of pituitary abscess proved by surgical pathology and clinical treatments were analyzed retrospectively.Results Pre-contrast MR showed hypointense heterogeneous intensity on T_1 WI in 12 cases and iso-hyperintense on T_1 WI in 2 cases,hyperintense on T_2 WI in all cases.Post-gadolinium MR showed the ring-like enhancement around the uneven edge of abscess and the surrounding enhanced meninges connecting to the focus.The normal pituitary could not be identified in all 14 cases.The MR specific findings include the fluid-fluid level,nodule on the edge and the enhanced patchy shadow.Conclusions The pituitary abscess has specific findings on MR examination,which can be used to combine with clinical symptoms to achieve the diagnosis before operation,so that the cases could be treated with antibiotic without operation.
