Objective To investigate the clinical effectiveness and safety of Chinese medicine fumigation-washing therapy in treating talipes equinus denervated ulcer induced by tethered cord syndrome(TCS) . Methods A total of 21 qualified patients were randomized into fumigation-washing group (N=12) and antibiotics group (N=9). Patients of fumigation-washing group were given fumigation-washing therapy with the self-prescribed Chinese medicine, and antibiotics group was given intravenous dripping of sensitive antibiotics. The treatment lasted for 7 continuous days. The clinical efficiency of the two groups was evaluated after treatment, and the period of preparing for surgery was recorded. The changes of ulcer area and ulcer surface exudate volume in the two groups were observed before and after treatment. And the changes in blood routine examination, hepatic and renal function, and immune function of the fumigation-washing group were monitored. Results(1) The total effective rate of fumigation-washing group was 83.3％, and that of the antibiotics group was 77.8％, the difference being insignificant (P>0.05). (2) The ulcer area and ulcer surface exudate volume in both groups were significantly decreased after treatment (P<0.05 compared with those before treatment), and the decrease in the fumigation-washing group was superior to that of the antibiotics group(P < 0.05).(3) The period of preparing for surgery in the fumigation-washing group was(7.75 ± 1.71)d, shorter than(11.56 ± 4.39) d in the antibiotics group, the difference being significant(P < 0.05).(4) There were no statistically significant differences in the hepatic and renal function, and immunoglobulin and complement levels in the fumigation-washing group before and after treatment (P > 0.05). (5) The average daily hospitalization fee in the fumigation-washing group was (47.98 ± 5.17) yuan, less than (227.88 ± 43.24) yuan in the antibiotics group, and the difference was significant between the two groups (P < 0.05). Conclusion Chinese medicine fumigation-washing therapy is effective, safe and practical in treating talipes equinus denervated ulcer induced by TCS, and the therapy has the advantages of decreasing exudation, promoting ulcer healing, reducing hospitalization fee, shortening the period of preparing for surgery, and decreasing the incidence of infection.

Objective To discuss the techniques and the prevention and cure of preoperative complications of the endovascular embolization in managing the intracranial aneurysms. Methods A total of 90 aneurysms in 88 patients were treated by detachable coils embolization. The clinical results and the management of complications were reported. Results Seventy aneurysms were occluded at 100%, 13 aneurysms at 90% to 95% and 5 aneurysms at only 80. The perioperative complications occurred in 9 patients, including the coil escaping from the aneurysm sac into its parent artery in 3 patients, re-rupturing of aneurysm in 4 patients during operation and serious vasospasm in 2 patients. Two patients died. Conclusion The endovascular embolization is a safe, effective and micro invasive method in managing intracranial aneurysms. The exact embolizing techniques chosen are very important to improve the curative results and decrease the complications of embolization of intracranial aneurysms.

Objective To investigate the effects of total flavonoids of Herba Epimedii(HEF)on the metabolism of typeⅠcollagen and the expression of cathepsin K in the bone of ovariectomized(OVX)rats. Methods Fifty-four female SD rats were allocated into 6 groups;OVX group,sham operation group,OVX rats followed by three doses of HEF(40,80 and 160 mg?kg~(-1)?d~(-1))and nilestriol(0.1 mg?kg~(-1)?d~(-1))for 12 weeks respectively.Bone mineral density(BMD)of whole body was determined by dual-energy X-ray absoptiometry.The level of cross-linked N-telopeptide of typeⅠcollagen(NTx)in the urine were determined by ELISA.The amounts of typeⅠcollagen protein and cathepsin K protein in bone tissue were detected by immunohistochemical method and Western blotting.Results Compared with OVX group,the total BMD values in the HEF treated groups were increased(all P＜0.05),and the expression levels of typeⅠcollagen in three HEF treated groups rose significantly in a dose-dependent manner after 12 week,and simultaneously,both the expression of cathepsin K in bone and the level of NTx/Cr were reduced markedly(P＜0.05),being most significant(P＜0.01)in the group treated with the highest dose of HEF(160 mg?kg~(-1)?d~(-1)).Conclusion HEF seems to be able to elevate BMD and improve bone quality of rats via promoting synthesis and inhibiting proteolysis and absorption of typeⅠcollagen in the bone.

Objective To investigate the effect and significance of microglia/macrophage activation prior to cerebral ischemic preconditioning (CIP) in regulating toll-like receptors 2 (TLR2)/nuclear factor-kappa B (NF-κB) inflammatory signaling pathway in early stage after ischemic brain injury in rats.Methods Thirty healthy male SD rats were selected and divided into normal control group,sham operation group,ischemia group,intervention group and treatment group according to random number table,with six rats per group.A rat model of focal permanent cerebral infarct was established by occlusion of middle cerebral artery (MCAO).CIP was performed by local ischemia-reperfusion.Minocycline was used to inhibit microglia/macrophage activation after CIP.Features of microglia/macrophage activation after CIP were detected by immunofluorescence; mRNA expressions of predominant factors (NF-κB inhibitor α,IκB-α;tumor necrosis factor α,TNF-α) of TLR2/NF-κB inflammatory signaling pathway in parietal cerebral cortex by in situ hybridization method; death rate by Kaplan-meier survival curves; neurological deficits by a 5-point neurological scale; brain infarct size by triphenyl tetrazolium chloride (TTC) staining.Results Microglia/macrophage started activation at one hour after cerebral ischemic injury in preconditioning group and presented a significant increase at 12 hours.Speed and range of activation were higher in preconditioning group than in ischemic group.IκB-α mRNA in preconditioning group started expression at one hour.TNF-α mRNA in preconditioning group remained a low expression in 12 hours and had a significantly lower peak value as compared with that in ischemic group (P ＜ 0.05).CIP increased rat survival rate significantly,improved nerve function and reduced infarction size when compared with the ischemia group (P ＜ 0.05).Minocycline inhibited nerve protection by CIP significantly (P ＜0.05).Conclusion CIP induces rapid activation of microglia/macrophage in early period of rat cerebral ischemic injury and provides brain protection probably via inhibition of TLR2/NF-κB activity and inflammatory overreaction to cerebral ischemia.

Objective To investigate the angiographic manifestation of the proper esophageal artery (PEA),the hish risk factom for the presence of the anomalous PEA in hemoptysis and to evaluate the safety of transcatheter aaefial embolization(TAE) of the PEA using gelatin sponge(GS).Methods Selective esophageal arteriography WSS performed in forty-three patients with hemoptysis,including 15 cases of pulmonary tuberculosis,18 cases of bmnchiectasis,7 cases of posttuberculous bronchiectasis and three cases of lung cancer. One case experienced failure of bronchial arterial embolization. The angiographic manifestation of the PEAs Was studied.The complications of the procedure and clinical results were observed in the patients who underwent TAE using GS.Results Thirty-nine PEAs were catheterized selectively in 37 patients(86.0%).Eighteen anomalous PEAs(46.2%)were catheterized selectively in 17 patients (45.9%).The anomalous PEAs showed tortuosity,dilatation,hyperplasia,shunting with pulmonary artery and anastomosis with the bronchial artery.All lesions involved basal segment of inferior pulmonary lobar. Bronchiectasis Was the most frequent disease for PEA abnormality. No complications occurred and satisfactory curative effect Was achieved with TAE of the anomalous PEAs.Conclusions It is necessary to perform selective proper esophageal arteriography when the lesion involves basal segment of inferior pulmonary lobar in hemoptysis.Supplemental TAE of the anomalous PEA using GS is safe and valuable in the management of hemoptysis.

Objective To explore the effect of wild type or mutant parkin gene expression on the growth of human hepatocellular carcinoma cell line Huh-7. Methods The parkin (wild type or mutant) expression vector and empty vector were transferred into Huh-7 cell lines with LipofectAMINE 2000 reagents. The positive clones that expressed parkin gene stably were chosen by G418 and checked by reverse transcription-polymerase chain reaction (RT-PCR) to check the DNA sequences. The cytobiological behaviors of those positive clones were analyzed by cell proliferation assay and tumorigenesis in nude mice. Results Huh-7 cell lines that expressed wild type or mutant parkin gene stably were successfully established. The growth of wild type parkin-expressed cells was obviously inhibited compared with the control cells transfected with empty vectors(t= 3. 875, P= 0. 031).The volume of tumor formed by wild type parkin-expressing cells in nude mice was also significantly reduced (t=8. 228,P=-0. 003). Mutant parkin gene expression had a slight effect on the growth of Huh-7 cells in vitro and in vivo (P＞0.05). Conclusion The re-expression of wild type parkin gene can favor the malignant phenotype revision of Huh-7 cells. Therefore, it might be a good candidate for tumor suppressor gene associated with HCC.

OBJECTIVETo investigate therapeutic strategy on septic arthritis after arthroscopic anterior cruciate ligament reconstruction.

METHODSThe clinical data of 6 cases of septic arthritis after arthroscopic anterior cruciate ligament reconstruction in our department from March 2005 to February 2014 were analyzed. All the patients were male,ranging in age from 18 to 36 years old. After operation, the knee joint became painful and swollen, and ESR and CRP were both increased. Culture of joint fluid allowed the recovery of staphylococcus epidermidis. The patients were dealt with arthroscopic debridement and infusion-drainage. The clinical results were evaluated by Lysholm rating system and range of motion.

RESULTSThe infection of all the patients was controlled. The ESR and CRP both recovered to normal level. The score of Lysholm rating system ranged from 85 to 95,and the range of motion was 120 to 135 degree.

OBJECTIVETo study the correlationship between TCM Syndrome type with changes of neutrophil surface intercellular adhesion molecule-1 (ICAM-1) and platelet membrane P selectin (CD62P) in patients with ischemic stroke for exploring the pathogenesis of the disease.

METHODSSeventy-two patients with ischemic stroke were dividcd into 3 typing groups according to TCM syndrome-differentiation, the Meridian-phlegm stagnancy group (MPS), the visceral phlegm-heat accumulation group (VPHA) and the qi-deficiency with blood stasis group (QDBS), 24 in each group. Besides, a control group consisted of 24 healthy subjects was set up. Blood levels of ICAM-1 and CDP62 expression were monitored by flow cytometry.

RESULTSBlood levels of ICAM-1 and CD62P expression in ischemic stroke patients were significantly higher than those in healthy subjects (P < 0.01). Among the three type groups, ICAM-1 expression was significantly higher in MPS than that in the VPHA and the QDBS group (P<0.01), and CD62P expression in the MPS and the QDBS group was significantly higher than that in the VPHA (P <0.01).

CONCLUSIONBlood levels of ICAM-1 and CD62P expression in different typing of patients with ischemic stroke are different. ICAM-1 expression reflects the pathological state of phlegm retention or phlegm-stasis mutual bindings, CD62P expression reflected the blood stasis state in organism, these evidences suggest that MPS may be the key pathogenic factor of ischemic stroke.
