BACKGROUND:The most effective method for the treatment of acetabular fracture is open reduction and internal fixation, however, this treatment for some special types of acetabular fracture cannot get satisfactory prognosis, and is prone to complications, such as traumatic coxarthrosis and avascular necrosis of femoral head. OBJECTIVE:To evaluate the curative effect of open reduction and internal fixation and total hip arthroplasty in the treatment of special acetabular fracture. METHODS:Twelve cases of acetabular fracture were included, including seven cases of traffic accident wound, three cases of crush injury, and two cases of fal ing injury. The type of bone fracture:two cases of posterior wal fracture, two cases of posterior column and posterior wal fracture, one case of T shaped fracture, five cases of transverse and posterior wal fracture, and two cases of acetabular roof sexual fracture. Complications:one case was femoral head centric dislocation, five cases were latter dislocation, and three cases were caput femoris fractures. Before injury, three cases had coxarthrosis, and two cases were avascular necrosis of femoral head. Al the cases were treated with open reduction internal fixation and total hip arthroplasty, of which nine cases were treated with biological prosthesis, and three cases were treated with bone cement prosthesis. The time from hospitalization to surgery was 3-15 days, and average was 6 days. The patients were fol owed-up once every 2 months in 1 year after replacement, and the Harris score was used to evaluate the hip function recovery. RESULTS AND CONCLUSION:No surgical site and deep wound infection, joint dislocation, lower limb deep vein thrombosis, and death were found in these 12 cases. Among them, 11 cases were fol owed-up for a longtime;the fol ow-up was lasted for 6-82 months. The acetabular fracture was healed at 6-16 months after reduction without prosthesis loosening and sinking. The hip function was evaluated during final fol ow-up according to the Harris score:excellent in eight cases, good in two cases, poor in one case, and the excellent and good rate was 91%. Open reduction internal fixation and one-stage total hip arthroplasty can avoid long-term bed, get out of bed as soon as possible, and reduce complications, thus reconstruct the hip joint painlessly and good functional y.

Objective To investigate the effect of prosthetic replacement for senior patients with unstable intertrochanteric fractures of the femur.Methods Fifty-three senior patients with comminuted intertrochanteric fracture of the femur were subjected to total hip arthroplasty (n =23) and bipolar artificial femoral head replacement (n =30).Uncemented long-stem prostheses were used in 50 patients and cemented long-stem prostheses in 3.Time interval between admission and surgery was 3-13 days (mean 6 days).Results The total hip arthroplasty had the operation time for mean 90 minutes (range,80-110 minutes) and blood loss for mean 350 ml (range,260-410 ml).While the hemiarthroplasty had operation time for mean 65 minutes (range,50-90 minutes) and blood loss for mean 230 ml (range,180-290 ml).Fifty-one patients were available to mean 49.6-month follow-up (range,13-65 months).Four patients presented with frequent hip pain at a tolerable level after hemiarthroplasty and the symptom was relieved after oral non-steroidal anti-inflammatory drug therapy.One patient with postoperative infection was cured by timely debridement.Seven patients were died of heart and brain disorders in 5 years,with no relation to surgical complications.The period for fracture healing was mean 10 months,with excellence rate of 96％ for hip function but with no acetabulum abrasion,implant loosening or submersion.Conclusion Early prosthetic replacement is an effective treatment for unstable intertrochanteric femoral fractures in the elderly.

OBJECTIVETo explore efficacy enhancing and detoxification roles of Jiedu Quyu Zishen Recipe (JQZR) in treating systemic lupus erythematosus (SLE) by studying its effect on Toll like receptor 9 (TLR9) signal pathway of murine macrophage cells after JQZR stimulated CpG oligodeoxynucletide (CpG ODN).

METHODSMurine macrophage cells in vitro cultured were randomly divided into 4 groups, i.e., the blank serum group, the CpG ODN stimulus group, the CpG ODN + dexamethasone group, the CpG ODN + medicated serum group. Murine macrophage cells were collected after 24-h intervention. The expression of TLR9, myeloid differentiation factor 88 (MyD88), NF-KB, IFN-α mRNA were analyzed by RT-PCR. The expression of TLR9 and NF-κB protein were analyzed by Western blot. Changes of the NF-KB transcriptional activity were assayed by Dual-Luciferase reporter assay system.

RESULTSmRNA expressions of TLR9, MyD88, NF-κB, and IFN-α, protein expressions of TLR9 and NF-κB, and NF-κB transcriptional activities were enhanced, showing statistical difference when compared with those of the blank serum group (P <0. 05, P <0. 01). Compared with the CpG ODN stimulus group, mRNA expressions of MyD88, NF-κB, and IFN-α, the protein expression of NF-κB and the NF-κB transcriptional activities decreased in the CpG ODN + dexamethasone group with statistical difference (P <0. 01). Compared with the CpG ODN stimulus group, mRNA expressions of TLR9, MyD88, NF-κB, and IFN-α, protein expressions of TLR9 and NF-κB, and NF-κB transcriptional activities were decreased in CpG ODN+ medicated serum group with statistical difference (P <0. 01).

CONCLUSIONEfficacy enhancing and detoxification roles of JQZR in treatment of SLE might be realized through regulating TLR9 signal pathways.

Objective:Position emission tomography/computed tomography(PET/CT) is a new bio-imaging system which is combined metabolic with anatomic imaging.This study was to compare the accuracy of conventional staging methods(including computed tomography,ultrasound,magnetic resonance imaging,and detection of bone marrow) with that of PET/CT for lymphoma staging and re-staging. Methods:A total of 42 patients with lymphoma diagnosed by operation or biopsy,received conventional and PET/CT staging.The accuracy of these two methods and their impact on lymphoma staging were compared.Results:The accuracy of PET/CT scan was 95.2%(40/42),and that of conventional staging was 78.6%(33/42).The detection rates of internal lymph node were 97.1%(66/68) and 88.2%(60/68),respectively.The detection rates of outer lymph node were 91.7%(22/24) and 58.3%(14/24),respectively.Compared with conventional staging methods,7 cases were up-staged and 2 cases were down-staged by PET/CT,which led to the change of therapy in 8 cases.Conclusion:PET/CT scan is more sensitive and accurate than conventional staging methods in staging and restaging of lymphoma.

OBJECTIVETo investigate the mRNA expression of monocarboxylate transporter 8 (MCT8), a thyroid hormone transport protein, in the lateral ventricle of rats with cerebral ischemia.

METHODSImmunofluorescence staining was used to observe the expression of MCT8 in the lateral ventricle of 5 normal SD rats. Another 20 adult male SD rats were randomized into 4 groups and subject to permanent ligation of both the common carotid arteries (2-vessel occlusion, 2VO) for 3 days, 2 weeks, or 5 weeks, or no ligation (control). At the end of the experiment, the transcriptional level of MCT8 in the brain tissue of the rats were detected using fluorescent quantitative PCR.

RESULTSMCT8 mRNA levels in 3-day and 2-week 2VO groups were comparable with that in the control group (P=0.909; P=0.694), but increased significantly in 5-week 2VO group compared with that in the control and 3-day 2VO groups (P=0.029; P=0.023). No significance was found in MCT8 mRNA between the 2-week and 5-week 2VO groups (P=0.065).

CONCLUSIONProlonged cerebral ischemia causes compensatory increase of MCT8 mRNA expression on the capillary endothelial cell membranes in the lateral ventricle of rats.

OBJECTIVETo evaluate the efficacy and safety of using Jiangzhi Tongluo Soft Capsule (JTSC) combined with Atorvastatin Calcium Tablet (ACT) or ACT alone in treatment of combined hyperlipidemia.

METHODSA randomized, double blinded, parallel control, and multi-center clinical research design was adopted. Totally 138 combined hyperlipidemia patients were randomly assigned to the combined treatment group (A) and the atorvastatin treatment group (B) by random digit table, 69 in each group. All patients took ACT 20 mg per day. Patients in the A group took JTSC 100 mg each time, 3 times per day. Those in the B group took JTSC simulated agent, 100 mg each time, 3 times per day. The treatment period for all was 8 weeks. Serum levels of triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C) were observed before treatment, at week 4 and 8 after treatment; and safety was assessed as well.

RESULTSAt week 4 and 8 after treatment serum TG decreased by 26.69% and 33.29% respectively in the A group (both P < 0.01), while it was decreased by 25.7% and 22.98% respectively in the B group (both P < 0.01). At week 8 decreased serum TG was obviously higher in the A group than in the B group (P < 0.05). Compared with before treatment, serum levels of LDL-C and TC levels decreased significantly in the two groups (all P < 0.01). There was no statistical difference in the drop-out value and the drop-out rate of serum LDL-C and TC levels (P > 0.05). At week 8 the serum HDL-C level showed an increasing tendency in the two groups. No obvious increase in peptase or creatase occurred in the two groups after treatment.

CONCLUSIONJTSC combined with ACT could lower the serum TG level of combined hyperlipidemia patients with safety.

This study was aimed to investigate the changes of the hypothalamic-pituitary-adrenal axis (HPAA) activity and the cytokines system in the hypothalamus of the depressive rats which were exposed to chronic unpredictable mild stressors (CUMS) after middle cerebral artery occlusion (MCAO). By means of qRT-PCR, ELISA and Western blot, mRNA and/or protein expressions of corticotropin releasing factor (CRF), tumor necrosis factors-α (TNF-α), suppressor of cytokines signaling 3 (SOCS3), phosphorylation of signal transducers and activators of transcription 3 (pSTAT3) were measured in the hypothalamus of rats. The results showed that, compared with control group, CUMS+MCAO group exhibited increased mRNA levels of CRF, TNF-α, SOCS3, as well as up-regulated CRF, TNF-α, SOCS3 and pSTAT3 protein expressions. Furthermore, there were correlations between CRF and TNF-α, TNF-α and SOCS3, SOCS3 and pSTAT3, respectively. These observations indicated the CRF system was activated in the post stroke depression (PSD) status. The TNF-α and its signaling pathway, STAT3/SOCS3, were up-regulated in mRNA and protein levels. In conclusion, this study presents the evidence which supports the hypothesis of signaling cross-talk between the CRF system and TNF-α signaling pathway after ischemic stroke and CUMS.

Objective To explore the relationship between self-reported chronic disease and smoking behavior among adult males in Jiangsu Province. Methods In 2007, 2010, and 2013 respectively, a multistage stratified cluster sampling method was used to select residents from 14 adult chronic diseases and their risk factor surveillance sites in Jiangsu Province to investigate the relationship between the prevalence of chronic diseases, smoking and smoking cessation behaviors among men aged 18 to 69 years. Results A total of 8 313 men aged 18 to 69 years had a self-reported prevalence of 1.5%, 1.1%, 1.5%, and 2.8% for cardiovascular and cerebrovascular diseases, malignancies, asthma, and chronic obstructive pulmonary disease (COPD), respectively.The self-reported prevalence of all four chronic diseases was higher in ex-smokers than in current smokers and non-smokers (all P<0.05).Multivariate analysis showed that the quit rate was of those suffering from cardiovascular and cerebrovascular diseases, malignancies, asthma, and COPD, respectively 3.356 times (95% CI: 1.966-5.728), 3.864 times (95% CI: 2.277-6.555), 2.103 times (95% CI: 1.321-3.345), and 2.586 times (95% CI: 1.872-3.573) higher, than those without. Conclusion Smoking cessation rates were significantly higher of those with chronic disease than those without, suggesting that illness would promote smoking cessation behaviors among smokers.
