Objective To observe and analyze curative efficacy of Desloratadine Citrate Disodium in combination with endoscopic sinus surgery and its effects on serum TIgE, ECP and inlfammatory factors in patients with chronic sinusitis.Methods 90 patients with chronic sinusitis who received therapy in our hospital from January 2015 to June 2016 were collected as research objects to be randomly divided into the control group and the observation group equally. The control group was given endoscopic sinus surgery, and the observation group was given Desloratadine Citrate Disodium in combination with endoscopic sinus surgery. Then, visual analogue scale (VAS) was applied to assess the severity of subjective symptoms of the disease. Three months after the surgery, the curative efifcacy, scores of visual analogue scale (VAS) relfecting clinical symptoms, levels of serum TIgE, ECP and inlfammatory factors were compared between the two groups.Results All patients undergone successful surgery. The observation group had a total therapeutic efifciency ratio of 95.6%, which was signiifcantly higher than that of 82.2% in the control group (P < 0.05). In comparison with the control group, the observation group had lower VAS scores of nasal discharge, nasal obstruction, cheek pain, headache, hyposmia [(1.84 ± 0.89) vs (3.12 ± 1.03) points, (1.87 ± 0.81) vs (2.55 ± 1.14) points, (1.24 ± 0.86) vs (1.88 ± 0.79) points, (1.15 ± 0.54) vs (1.97 ± 0.83) points, (1.84 ± 0.73) vs (2.18 ± 0.84) points], lower levels of serum TIgE, ECP [(58.62 ± 7.36) vs (64.39 ± 7.18) kU/L, (4.25 ± 0.84) vs (5.01 ± 1.07) ng/L)] and inflammatory factors of TNF-α, IL-6, IL-8 [(1.27 ± 0.46) vs (2.62 ± 0.53) ng/ml, (5.13 ± 1.24) vs (9.54 ± 2.23) pg/ml, (282.63 ± 32.42) vs (315.84 ± 35.89) ng/L)] with statistical differences (allP < 0.05).Conclusion Desloratadine Citrate Disodium in combination with endoscopic sinus surgery is effective for chronic sinusitis, which can signiifcantly relieve clinical symptoms, reduce levels of serum TIgE, ECP and alleviate inlfammatory reaction.

Interferon (IFN) is one of the commonly used anti-HBV drug in clinic,in which IFN-λ is a new type of IFN,including IFN-λ1,IFN-λ2 and IFN-λ3 (also called IL-29,IL-28A and IL-28B,respectively).Researches in recent years show that IFN-λ3 (IL-28B) polymorphism seems to be involved in the onset of hepatitis B,the response to antiviral therapy and the outcome of HBV infection.This paper reviews the correlations between IL-28B polymorphism and the spontaneous clearance of HBV,the progression of HBV infection,the occurrence of liver cancer and the therapeutic effect of IFN treatment.

Objective To explore the similarities and differences in amplitude of low frequency fluctuation ( ALLF) between patients with first-episode drug-naive schizophrenia and offspring of schizophrenia patients.Methods ALFF values were estimated by measuring the Blood Oxygen Level-Dependent ( BOLD) signal using resting state function-al magnetic resonance imaging ( rs-fMRI) .The fMRI date were acquired from 23 patients with first-episode drug-naive schizophrenia (SZ), 25 offsprings of schizophrenia patients (OS) and 29 age -and gender -matched health controls ( HC) .The ALFF value of each subject was calculated by MATLAB-based DPARSF software.Results Compared with HC, the ALFF values of SZ and OS were significantly different in the left posterior part of the inferior temporal gyrus, left parahippocampal gyrus, left hippocampus, right postcentral gyrus and bilateral precuneus.The ALFF values were not signif-icantly different between these two groups in the aforementioned regions.Compared with OS and HC, the ALFF values of SZ were significantly different in the left anterior part of the inferior temporal gyrus, left temporal pole and bilateral calcarine cortex.But there was no significant difference between OS and HC.Conclusions The brain function is abnormal in pa-tients with early schizophrenia and offspring of schizophrenia patients.The significant difference of ALFF in the left posterior part of the inferior temporal gyrus, left parahippocampal gyrus, left hippocampus, right postcentral gyrus and bilateral pre-cuneus may suggest the heredodiathesis-related brain functional alterations.Significant difference of ALFF in the left ante-rior part of the inferior temporal gyrus and the left temporal pole bilateral calcarine cortex may suggest the disease-related brain alterations.

Objective To analyze complications of carotid artery stenting (CAS) and preventions.Methods Clinical data and treatment outcomes of 72 consecutive patients ( 80 stents ) from July 2006 to January 2012 with carotid stenosis were analyzed.Asprin 100 mg and clopedigrel 75 mg were given orally 5 days before CAS.Distal embolic protection device were implanted in all patients,pre-dilatation was done for those with carotid stenosis ＞ 90％ and post-dilatation was done for those of residual stenesis ＞ 30％.Severe complications of CAS mean death,myocardial infarction (MI) and stroke.Other minom included transient ischemic attack ( TIA ),hyperperfusion and intracranial hemorrhage ( ICH ),bradycardia and/or hypotension,hypertension,access hematoma or bleeding.Results In 72 patients a total of 80 self-expandable bare stents were successfully implanted.Distal embolic protection devices were used in all cases.Combined procedure was taken in 5 cases including OPCABG in 2 cases,left subclavain artery stenting in 2 cases and renal artery stenting in 1 case.The overall in-hospital complications was 37.5％ (27 of 72).Of these events,1 case had minor strokes defined as a modified Rankin Scale score less than 3 at 1-year follow-up,2 patients (2.78％ ) experienced a hemispheric TIA (neurological symptoms that resolved within 24 hours),1 patient experienced hyperperfusion syndrome.The overall mortality rate was 0,21 cases (29.2％ ) experienced hemodynamic instability (hypotension in 15 cases,bradycardia in 5 cases and hypertension in 1 case) and 2 others had access hematoms.The 30-day death/stroke/myocardial infarction risk was 1.39％ (1 minor stroke).Conclusions Hemedynamic instability (hypotension and bredycardia) is main complications of carotid artery stenting in patients with carotid artery stenosis,severe complications are rare.

Objective To investigate the effects of preemptive analgesia with parecoxib sodium on postoperative analgesia and delirium after nerve injury-free surgery for fracture of thoracic and lumbar vertebrae and to promote the postoperative rehabilitation of the patients. Method 80 patients meeting the criteria were selected. and randomly divided into observation group and control group.40 patients each group. The observation group used parecoxib sodium for preemptive analgesia. while the control group used sufentanil. and the analgesia effects and the incidences of delirium were observed. Results The differences in operative time and intra-operative blood loss between the patients of the two groups were statistically insignificant. In 2 h. 6 h. 12 h.24 h and 48 h after the surgery.the VAS score and the accumulative time of intravenous self-controlled analgesia pump being pressed of the observation group were significantly lower than those of the control group. and the differences were statistically significant (P<0.05). The first time for the patients of the observation group to press the intravenous self-controlled analgesia pump is (3.84±0.62) h after the surgery, is significantly later than that of the control group (1.05±0.47)h.and the difference is statistically significant (P<0.05). The incidence of delirium in 7 days after the surgery in the patients of the observation group was 10.00%. and is significantly lower than that of the control group (25.00%) (P<0.05). Conclusion Using parecoxib sodium for preemptive analgesia before nerve injury-free surgery for fracture of thoracic and lumbar vertebrae can elevate the postoperative analgesia effects of the patients.decrease the incidence of postoperative delirium, and is highly safe and consequently worthy of clinical application.

BACKGROUND: Insulin-like growth factor-1 (IGF-1) is a peptide hormone, it has been proved a promotion role on the proliferation of precursor cells. OBJECTIVE: To explore the intravenous injection of IGF-1 on the proliferation, migration and differentiation of neural stem cells in rats after cerebral ischemia. METHODS: Eight adult male SD rats were randomly divided into control group and experimental group, with 40 rats in each group. The rats in two groups were used to prepare models of focal cerebral ischemia using modified suture method, the rats in the experimental group were treated with tail vein injection of IGF-1, according to 100 μg/kg computation, the injection was given for 6 continuous days; in the control group, rats were given equal volume of saline. The rats were decapitated at 7, 14, 21, 28 days following intervention, respectively, and rats in each group were given intraperitoneal injection of the BrdU at 1 day before death. Immunohistochemistry and double staining were applied to detect the expressions of BrdU-positive cells, PSA-NCAM-positive cells, BrdU + PSA-NCAM double-positive cells, and BrdU + MAP2 double-positive cells. RESULTS AND CONCLUSION: The number of BrdU-positive cells and PSA-NCAM positive cells reached the peak at 7 days after ischemia; BrdU + PSA-NCAM double-labeled-positive cells could be detected in ischemic bilateral subependymal zone and dentate gyrus, the number was the most at 7 days, then followed by a gradual decrease; the BrdU + MAP2 double-positive cells began to increase from 14 days, and then gradually increased along with the decrease of BrdU + PSA-NCAM double-positive expression, showing a reverse trend. Intravenous injection of IGF-1 can induce the proliferation, differentiation and migration of neural stem cells in rats following ischemic brain injury.

Objective To summarize the efficacy of cervical pedicle screw fixation in the treatment of cervical spinal cord injury without fracture and dislocation.Methods From September 2007 to March 2010,21 patients with cervical spinal cord injury without fracture and dislocation combined with developmental cervical stenosis were managed by pedicle screw fixation in unstable segments,and then single open-door laminoplasty in stenosis segments.The clinical outcomes were reviewed and summarized.Results All the patients received follow-up of 1-3 years.Two patients had superficial wound infection,which was cured by dressing change.One presented intra-incisional hematoma one week post-operatively and was cured by hemostasis and drainage.One had door-reclosing without symptom aggravation.There was neither perforation of pedicle screws nor breakage,loosening or displacement of internal fixation.The curvature of cervical lordosis at follow-up had significant rectification in comparison with that at preoperation,but showed unobvious change as compared with that immediately after operation.According to the modified Japanese Orthopedic Association (JOA) score,the neurological score improved from preoperative 4-15 points to 9-17 points at the final follow-up,which revealed more than 80％ of recovery in 13 patients,50％ -80％ of recovery in six and 5％ -50％ of recovery in two,with the average recovery rate of 75％.Conclusion For unstable segments in patients with cervical spinal cord injury without fracture and dislocation combined with developmental spinal stenosis,posterior pedicle screw fixation can avoid the risk of further spinal cord injury in single open-door laminoplasty and restore the physiological curvature of cervical vertebrae,which provides solid foundation for backward drift of spinal cord and creates favorable condition for recovery of spinal cord function.

BACKGROUND: During thoracolumbar anterior operation, implant collapse is an important factor for affecting outcome in patients with thoracolumbar fracture. In particular, osteoporotic patients commonly developed implant collapse, nail channel loose, bone disunion, kyphosis deformation. Bioactive artificial vertebrae of nano-hydroxyapatite and polyamide 66 (n-HA/PA66) has good biocompatibility and biological safety and is an ideal substitute for vertebral body bone graft. OBJECTIVE: To investigate the efficacy of the bioactive artificial verteificial vertebrae of nano-hydroxyapatite and polyamide 66 (n-HA/PA66) for osteoporotic thoracolumbar burst fracture. DESIGN, TIME AND SETTING: A retrospective case analysis was conducted at the Department of Spinal Surgery, Affiliated Hospital of Luzhou Medical College from January 2004 to January 2008. PARTICIPANTS: A total of 20 patients with moderate and severe osteoporotic thoracolumbar fracture (6 males and 14 females) aged 51 -82 years, with an average of 69 years were enrolled in this study. There were 17 cases of fresh fracture and 3 cases of old fracture. n-HAyPA66 was produced by the Sichuan Guona Science and Technology Co., Ltd. This artificial vertebral body was in 10-35 mm diameter, 30-100 mm length, circular cylinder shape, 3-12 mm midheaven diameter, 2.5-6.5 mm tubal wall thickness, with the presence of 2 mm holes surrounding the vertebral body. The contact area of the vertebral body was 78.5-176.7 mm2. Fixity was anterior nail plate system (titanium alloy material) produced by Foshan Shitaibao Company. METHODS: Following conventional tracheal intubation and general anesthesia, at right arm recumbent, according to various fracture-involved segments, different regions were incised and treated with anterior decompression, implanted with artificial vertebrae with the bioactive artificial verteificial vertebrae n-HA/PA66 and fixed with steel plate. MAIN OUTCOME MEASURES: Fracture healing and implant loose were observed by radiograph. Cobb angle, the height of damaged vertebral body and spinal cord function score were compared prior to surgery, 3 months following surgery and the last follow-up. RESULTS: All the patients were successfully operated. Bleeding 200-800 mL during surgery and operation time ranged from 2.0 to 3.0 hours. There were 1 case of pulmonary infection and 1 case of delayed wound healing. A total of 20 patients were followed up for 6-42 months (averagely 18 months). Postoperative radiograph review demonstrated that closed vertebral body was healed three to four months. No significant displacement of implant was found. There was less loss of reestablished vertebral body height. Internal fixation position was good, without nail breakdown or internal fixation loose/displacement. At 3 months following surgery, significant differences in Cobb angle, the height of damaged vertebral body and spinal cord function score were detected compared with that before surgery (P < 0.05). No significant difference in postoperative two follow-up was detected (P > 0.05). CONCLUSION: The bioactive artificial vertebrae of n-HA/PA66 can increase the fusion area, reduce local pressure and prevent loosening of implants and sinking into the vertebrae, finally resulting in restoration of vertebral body height.
