ObjectiveTo study effect of rehabilitation on the sequelae of encephalitis. Methods 41 patients were divided into two groups, Group A( only treated with traditional Chinese medicine)and group B ( treated with both traditional Chinese medicine and rehabilitation). Each patient was evaluated before and after the treatment. Result The treatment in the group B was significantly better than that in the group A (P<0.05), especially in motor function. Conclusion Comprehensive rehabilitation is an effective therapy on the sequelae of encephalitis, which shortens the course of the sequelae and improves the motor function and speech.

Objective To evaluate and compare the presence of the nerve root sedimentation sign in patients with lumbar spondylolisthesis (LS) and lumbar disc herniation(LDH). Methods One hundred and fifty-one patients with degen?erative lumbar spinal disease treated by surgery from July 2012 to March 2014 were reviewed retrospectively in Tianjin Hos?pital. All the patients were divided into two groups:LS group (48 cases) and LDH group (103 cases). The clinical outcomes were evaluated by Japanese Orthopedic Association (JOA). The probability of positive sedimentation sign was compared be?tween LS group and LDH group. Correlation between the JOA score and nerve root sedimentation sign were analysed in two groups. Results There was no statistical difference in JOA score between LS group and LDH group (15.83±3.57 vs 16.76± 3.10, t=1.624, P=0.107). A positive sedimentation sign was identified in 39 patients in the LS group (81.25%) but in 65 pa?tients in the LDH group (63.11%). The difference between LS group and LDH group was statistically significant(χ2=5.028, P=0.031). In LS group, JOA scores of patients with positive nerve root sedimentation sign were lower than those of patients with negative nerve root sedimentation sign(15.33±3.50 vs 18.00±3.20, t=2.092,P=0.042);but in LDH group, there was no statistical difference in JOA scores of patients between positive nerve root sedimentation sign and negative nerve root sedi?mentation sign (16.40±3.13 vs 17.37±2.99, t=1.539, P=0.127). Conclusion A positive sedimentation sign also occurs in pa?tients with LDH, but positive nerve root sedimentation sign are more likely to appear in patients with lumbar spondylolisthe?sis who have worse clinical symptoms.

This article was aimed to study anti-inflammatory effects of petroleum ether extract from Citrullus lanatus vine (PEECLV) and explore the mechanism. The methods of ear swelling with xylene, increasing of peritoneal capil-lary permeability, and paw edema with egg albumin were used in the establishment of mice models, respectively. Granuloma with cotton pellet, and paw edema with carrageenan were used in the establishment of rat models, re-spectively. Observation was made on anti-inflammatory effects of PEECLV. The content of nitrous oxide (NO) and nitric oxide synthase (NOS), as well as the level of TNF-α and IL-1β in blood serum were measured among granu-loma with cotton pellet rat models. Contents of malondialdehyde (MDA), prostaglandin E2 (PGE2), 5-HT, histamine (His), and protein in inflammatory exudates from the paw edema with carrageenan rat model, as well as contents of NO and NOS in blood serum, and activity of superoxide dismutase (SOD) were measured in order to study the possi-ble anti-inflammatory effects. The results showed that PEECLV can suppress the ear swelling with xylene, the in-creasing of peritoneal capillary permeability, and the paw edema with egg albumin in mice, as well as granuloma with cotton pellet, paw edema with carrageenan in rats. It had anti-inflammatory effects at different degrees. The content of NO and NOS, as well as the level of TNF-α and IL-1β in blood serum were reduced in granuloma with cotton pellet rat models. The content of MDA, PGE2, 5-HT, His, and protein content were reduced in inflammatory exudates from the paw edema with carrageenan rat model. The increasing of NO and NOS in blood serum was inhib-ited. And the activity of SOD was increased. It was concluded that PEECLV had certain anti-inflammatory effects. Its mechanism may be related to the influence of the production of inflammatory mediators and antioxidant.

Objective To observe changes in bone mass and symptom duration in patients with lumbar disc herniation(LDH) and explore the relationship between osteoporosis and clinical features of LDH. Methods 83 LDH patients undergoing surgery were enrolled in the study from November 2008 to September 2009. Before surgery, dual-energy X-ray absorptiometry was used to detect bone mineral density of lumbar spine and hip, and calculate T score. The patients were divided into three groups according to the T score: group A (normal bone mass group, n=27), group B (osteopenia group, n=31) and group C (osteoporosis group, n=25). The differences in the duration of symptoms and pathological types were compared between the groups. The relationship between BMI and lumbar spine T-score was explored. Results There were no significant differences in the pathological types among the three groups. The symptom duration in group C was significantly shorter than in group A (P < 0.05). There was no correlation between BMI and lumbar spine T-score (r=0.20, P=0.070). There was positive correlation between BMI and Hip T-score (r=0.263, P=0.016). Conclusion Osteoporosis may affect the symptom duration of LDH patients. We should attach great importance to patients with osteoporosis and LDH.

Objective To explore the application value of minimally invasive surgery in the treatment of lumbar spinal tuberculosis, and to provide reference for clinical treatment of spinal tuberculosis. Methods Data of 252 cases of patients with lumbar spinal tuberculosis treated by conservative treatment in our hospital from January 2005 to December 2014 were retrospectively analyzed. Patients were divided into four groups on the basis of systemic application of antituberculosis chemotherapy. A total of 154 patients were given simple local chemotherapy of percutaneous placement of focus catheter (group A), 48 patients were received percutaneous perfusion drainage and local chemotherapy (group B), 32 patients underwent percutaneous puncture catheter debridement combined with local chemotherapy (group C), and 18 patients were given percutaneous debridement and internal fixation combined with local chemotherapy catheter (group D). Data of erythrocyte sedimentation rate (ESR), visual analogue scale (VAS), Oswestry disability index (ODI) score and the modified MacNab criteria were recorded before operation and at the end of the follow-up in four groups of patients. Results Of the 252 patients, 228 were followed up and 214 patients achieved clinical cure. The lost access were15 cases in group A, 5 cases in group B, 2 cases in group C and 2 cases in group D. The total rate of lost visit was 9.52%. The follow up duration ranged from 25-126 months. The mean duration of follow-up was 68(60, 76) months. A total 214 cases reached the standard of clinical cure. No complications (retrograde infection and cross infection) were found in all patients during treatment. ESR was statistically decreased to (7.26 ± 3.43) mm/1 h at the last follow-up (t=35.06, P=0.023) compared with that (44.96 ± 12.42) mm/1 h before operation. The VAS and ODI were 1.5(1, 3) and 30(25, 35)% at the last follow-up, which were significantly improved than those [7.5(7.0, 8.0) and 60(55, 65)%] before operation (Z=13.641 and 6.806, P<0.05). According to the improved MacNab criteria, the overall excellent and good rates for patients were 86.4%(197/228) at the last follow-up. Conclusion According to the stepped care and personalized treatment, patients of lumbar tuberculosis are preoperative comprehensive evaluated, and most patients can achieve long-term stability and a better clinical efficacy after interventional and minimally invasive treatment.

Objective To investigate the effects of different cyclic tensile strains on the proliferation and expression of bone marrow stromal cells (BMSCs)-cocultured human degenerated anulus fibrosus (AF) cells. Methods AF cells were isolated from a patient with degenerated intervertebral disc degeneration (IVD), which were co-cultured with BMSCs. The solely cultured AF cells were used as control group. The two groups of cells were expanded in monolayer, and cyclically strained for 3 hours, which were applied 0, 5%, 10%, 15%and 20%strains at a frequency of 0.25 Hz using BioDynamic test instrument. A flow cytometry method was used to examine the AF cell proliferation at 24 hours followed the application of cyclic tensile strains. After the total RNA was extracted, real-time PCR technology was used to detect the gene expression of collagenⅠand aggrecan. Results Under the same appropriate stress, the proliferative index (PI), the proportion of cells in the period of DNA synthesis, the expression of collagenⅠand aggrecan were significantly higher in the co-cultured group than those of control group (P<0.05). However, the best mechanical stimulation was different in the two groups. For the AF cells, the peaks of PI, the proportion of cells in the period of S period, the expression of collagenⅠand aggrecan were found in the 10% strain group, while for the co-cultured cells, they were found in the 15% strain group. Conclusion Co-culturing with BMSCs has a positive effect on the proliferation and expression of human degenerative fibrous ring cells, which can protect AF cells from bad stress stimulation.

Objective To assess the effect of repetitive transcranial magnetic stimulation (rTMS) on motor and ambulatory function in incomplete spinal cord injury (SCI) patients. Methods 18 incomplete SCI patients (AIS D) were randomized to treatment group (n=10) and control group (n=8). The treatment group received rTMS while the control group received sham stimulation for 2 weeks. All the patients received routine rehabilitation. They were assessed with Lower Extremity Motor Score (LEMS), 10 m Walking Test for Walking Speed, modified Ashworth scale (MAS), Walking Index for SCI Scale II(WISCI II), and Spinal Cord Independence Measure (SCIM) before and after treatment, and followed up for 2 weeks after treatment. Results The treatment group significantly improved in LEMS, walking speed, and SCIM after treatment and during follow up (P<0.05), while the control group improved only in SCIM (P<0.05). There was more significant improvement in LEMS in the treatment group than in the control group (P<0.05) after treantment and during follow up. There was no difference between two groups in MAS, walking speed, WISCI II and SCIM. Conclusion rTMS can further improve the motor of lowere limbs for incomplete SCI patients.

Objective To explore the best therapeutic methods for acute mesenteric venous thromboses(AMVT)with different degrees of intestinal ischemic lesions. Methods 6 cases of acute abdomen were preoperatively diagnosed as AMVT with imaging. After laparotomy, patients were classified as congestive lesion(n=3)and necrotic lesion(n=3)according to the degree of intestinal sichemia and were treated with mesenteric thrombectomy and bowel resection, respeetively. All cases received heparin and urokinase perioperatively. Results Of the 3 patients receiving mesenteric thrombectomy, 2 were cured and the other one with ischemic ascending colon was cured after right hemicolectomy due to the complication of colic dynamic ileus and perforation 10 days after thrombectomy. The other 3 patients recovered after bowel resection. Follow-up from 8 months to 6 years showed no recurrence. Conclusion Combined with anti-coagulation therapy, thrombectomy and bowel resection are rational and effective protocol for congestive lesion and necrotic lesion, respectively in AMVT patients.

Objective To explore the status of infection, biotype and resistant background of epi-demic strains of Haemophilus influenza ( Hi ) in neonates, and the clinical features of neonatal pneumonia caused by Hi. Methods The multicenter prospective epidemiological cross-sectional design was used; four hospitals in west Sichuan China were chosen as research field,sputum bacterial culture was done and biologi-cal typing,PCR identification and drug sensitivity test of Hi epidemic strains were carried out among 0 to 28 days hospitalized neonates with infectious pneumonia in four hospitals located in west Sichuan China. The ca-ses with discharge diagnosis of neonatal infectious pneumonia with Hi positive separation were assumed as case group,and the same number of cases with Hi negative separation were assumed as control group accord-ing to 1∶1 extraction at the same time. Results Totally 757 cases with admitting diagnosis of neonatal infec-tious pneumonia in four hospitals were investigated in west Sichuan from November 2014 to October 2015, and the rate of sputum culture was 95. 51%(723/757). The total pathogenic bacteria positive rate of sputum culture was 15. 63%(113/723),and Hi positive rate was 1. 94%(14/723),Hi accounting for 12. 39%(14/113) of the pathogenic bacteria in respiratory system. All the Hi strains(100%) were non-typeable Hae-mophilus influenzae( NTHi) indentified by PCR. The main biotypes of 14 Hi strains were typeⅠwith 57. 1%(8/14),type Ⅲ with 14. 3%(2/14) and type Ⅳ with 28. 6%(4/14). The total of 35. 7%(5/14) bacterial strains of β-lactamase distributed in four hospitals,7. 1%(1/14) bacterial strains of β-lactamase-nonproduc-ing-ampicillin-resistant,and 35. 7%(5/14) bacterial strains of β-lactamase-positive-ampicillin-resistant were found in four hospitals. The rate of resistance and mediation to cefuroxime were 14. 2%(2/14) respectively, the resistance rate to cefaclor was 35. 7%( 5/14 ) , and 21. 4%( 3/14 ) to ofloxacin. None of the 14 strains was resistant to amoxicillin clavulanic acid and cefotaxime. The 1∶1 matching analysis had been done for 10 cases with discharge diagnosis of neonatal pneumonia caused by Hi. There were no statistical differences in general conditions,main symptoms, lung signs, X-ray appearance, classification of leukocyte and C-reactive protein levels between case group and control group(P>0. 05). Conclusion All the Hi isolated from spu-tum were NTHi among 0 to 28 days inpatients with neonatal pneumonia and the main biotype were typeⅠ, type Ⅲand typeⅣin west Sichuan China. There were no significant differences in the clinical manifestations of neonatal pneumonia with NTHi infection and other infectious pneumonia.

Objective Infliximab is a kind of recombinant human mouse chimeric anti-tumor necrosis factor monoclonal antibody. Here we aimed to examine the impact of infliximab therapy on RANK/RANKL/OPG system in the peripheral blood of rheumatoid arthritis (RA) patients. Methods Fifty patients with RA were rigorously screened and randomly divided into 2 groups. One group was treated with infliximab (3 mg/kg)and methotrexate (MTX). As control, the other group was treated with MTX alone. Infliximab was administered at weeks 0, 2, 6 and 14. The expression of RANK, RANKL mRNA in the peripheral blood, serum OPG and clinical indicators changes at week 0 and 18 were compared.x2-test or t-test were used for statistical analysis.Results After treated with infliximab, bone damage of joints were slowed down when examined by radiography in RA patients compared with the control group. And the ratio of OPG/RANKL was also decreased in RA peripheral blood (w0: 80.25;w 18: 63.2); (control group w0: 83.37; w18: 30.87)(P＞0.05). Although after the treatment with either MTX alone [w0: (238±15) pg/ml; w18: (118±10) pg/ml] or infliximab combined with MTX [(w0: (223.1±6.2) pg/ml; w18:(162.4±5.5) pg/ml], the serum levels of OPG were all decreased (P＞0.05), the level of OPG in infliximab treatment group was declined slower than those in the control group. Conclusion RA bone destruction can be inhibited by the combination therapy of infliximab and MTX. The mechanism may be partly through the RANK/RANKL/OPG system.
