Objective To evaluate the clinical outcome of total hip arthroplasty (THA) for protrusio acetabuli. Methods Between 2003 to 2008, 31 patients(35 hips) with protrusio acetabuli were treated with THA, including 16 males (18 hips) and 15 females (17 hips). The age ranged from 36 to 71 years (average age 52.2 years). The femoral heads were moved out with retrograde method when necessary via posterior-lateral hip incision. The acetabular loops and bottoms were prepared respectively. Auto-bone grafting was used to repair acetabular defects and cementless prostheses were planted with press-fit skills. At follow-up visit,the hip functions were evaluated by Harris score. The loosening, re-protrusion and the union of graft bone was judged by X-ray. Results The mean follow-up was 46.5 months (19-152 months). One patient developed DVT on the second day post-operatively who recovered well after anticoagulation treatment. One patient complained of gentle thigh pain which disappeared at 6 months. No other complication was found. The mean Harris scores had improved from 48.9±6.5 pre-operatively to 91.2±5.7 post-operatively. All prostheses acquired bone stabilization with no sign of loosening and re-protrusion and the grafts bone were healed at a mean 6 months according to X-ray. Conclusion THA with acetabular bone grafting and cementless component for protrusio acetabuli have acquired excellent results and prevented loosening and re-protrusio effectively.

Objective:To explore the clinical outcomes of anatomical double-bundle medial patellofemoral ligament (MPFL) reconstruction with double suture anchor technique in treating patellofemoral instability in adolescent.Methods:Twenty-five young people with patellofemoral instability (25 knees) in our department from January 2013 to December 2014 were enrolled for this study.All patients were performed anatomical double-bundle MPFL reconstruction with arthroscopic-assisted suture anchors technique in the patella,and fixed in the femoral socket with absorbable interference screw.All patients are evaluated by different methods,including patient's satisfaction,patellar apprehension test,recurrent subluxation/dislocation,CT assessment of bone tunnel and patellar tilt angle.Lysholm scores,Tegner scores and Kujala scores were recorded at the final follow-up.Results:The mean follow-up was 24 (range 20-40) months.All cases were observed in negative patellar apprehension test.Infection,recurrent subluxation/dislocation and patellar fracture were not found at the last follow-up.CT results demonstrated that the tunnel position were good.The patellar tilt angle was decreased from 21.6°±2.3° to 10.5°±1.6° (P＜0.05);the Lysholm scores was increased from 51.7±5.3 to 93.8±6.5 (P＜0.05).Tegner scores was increased from 4.1± 1.1 to 5.5±0.6 (P＜0.05).Kujala scores was increased from 53.5±6.4 to 94.6±4.3 (P＜0.05).Conclusion:Arthroscopic-assisted anatomical double-bundle MPFL reconstruction with the suture anchors technique is a safe,minimal invasive and effective surgical option for treating patellofemoral instability in adolescent.

Objective To investigate the immunoregulatory effects of bone marrow-derived mesenehy-real stem ceils (BMSCs) combined with leflunomide (LEF) on mice T-lymphocytes in vitro. Methods BMSCs from BALB/c mice were isolated and expanded. The purity of BMSCs was identified by flow cytometry (FCM). The BALB/c mice's spleen lymphocytes were isolated by using EZ-Sep<'TM> Mouse 1X. Under ConA stimulation, spleen lymphocytes were pretreated with LEF, then washed and co-cuhured with BMSCs. We set up four groups to investigate in this study: group A, spleen lymphocytes alone; group B, spleen lymphocytes with BM- SCs; group C, LEF-pretreated spleen lymphocytes alone and the group D, LEF-pretreated spleen lymphocytes with BMSCs. T-lymphocytes proliferation was assessed by MTT. FCM was used to analysis T-lymphocytes apoptosis and surface markers of CD69 and CD28. The mRNA expression of interleukin (IL)-2, IL-10 were detected by real-time RT-PCR. Results In vitro, the T-lymphocytes'values of A570 nm were significantly lower in group B and group C, compared with group A (group B vs group C vs group A, 0.578±0.042 vs 0.502± 0.040 vs 0.778±0.035, P<0.01), while the value of A<,570 nm>in group D was 0.218±0.033, which was also obviously lower than that in group B and group C (P<0.01). There were no suppressing effects on T-lympho-cytes'activation and expression of IL-2 had been observed. The proportion of apoptotic T-lymphocytes in group B and group D were (2.29±0.32)％ and (4.22±0.98)％, which was significandy lower than that in group A (8.08±1.20) (P<0.01). The expression of IL-10 in group B and C were also lower than that in group A (group B vs group C vs group A, 0.098±0.039 vs 0.054±0.022 vs 1.000, P<0.01 ). Either, the expression of IL-10 in group D was 0.023±0.015, which was obviously lower than that in group B and group C (P<0.01). Conclusion BMSCs combined with LEF show synergistic immunoregulatary effects on mice's T-lymphoeytes.

Objective To provide experimental evidence for the development of multi-epitope-baseded marker vaccines through investigating the humoral and cellular immune responses in BALB/c mice induced by the multiple antigen peptides (MAPs) with the mimic epitope.Methods Three types of MAPs in eight branched forms containing the mimic epitope of Mycoplasma genitalium adhesion protein (MgPa) were prepared using poly-lysine as the core matrix.The purity of MAPs was analyzed by reverse phase high performance liquid chromatography (RP-HPLC).The molecular weights of MAPs were characterized by Mass Spectrometry.The BALB/c mice were immunized intramuscularly for four times with single or mixed MAPs.The specific IgG antibody and the subtype of IgG antibody in serum of the immunized mice were detected by indirect ELISA.The proliferative responses of the spleen lymphocytes were detected using MTT assay.The ELISA were used to detect IFN-γ and IL-4 levels in the cultured supematant of spleen lymphocytes.Results The three types of MAPs containing the mimic epitopes were successfully prepared with high purity.They,could stimulate mice to produce specific IgG antibodies,of which,the major antibody isotype was Th1 immune response-associated IgG2a.Compared with the single MAP immunization group,the mixed-MAPs immunized mice produced more IgG,IgG1 and IgG2a antibody (P＜0.05).Furthermore,these MAPs could enhance the specific proliferation of spleen lymphocytes in immunized mice and induce the production of IFN-γ and IL-4.The levels of IFN-γand IL-4 in mixed-MAPs group were significantly higher than those of the single MAPs group (P＜0.01).Conclusion The three types of MAPs could induce strong specific cellular and humoral immune responses.The immunological competence of the mixed-MAPs was stronger than those of the single MAP.

Objective To isolate and culture sweat gland epithelial cells in vitro,and to study the effects of acetylcholine (ACh) on intracellular flee calcium concentration ([Ca~(2+)]i) of cultured sweat gland epithelial cells.Methods Sweat glands epithelial cells were collected by enzymatic digestion.After ACh was added to the primary and first passage cells,[Ca~(2+)]i was examined using confocal laser scanning microscopy (CLSM) and the Ca~(2+) sensitive dye Fura 3/AM.Results The primary and first passage epithe- lial cells grew well.After ACh was added,opening of the calcium channel and significant [Ca~(2+)]i increase were observed when the primary and first passage cells were incubated with high concentration of calcium (2 mmol/L);no significant [Ca~(2+)]i increase was observed in those cultured without calcium.Conclusion Upon stimulation with ACh,calcium channels of cultured primary and first passage sweat gland epithelial cells would open,influx of extracellular Ca~(2+) occurred,which resulted in an increase of [Ca~(2+)]i.Extracellular bound calcium was therefore converted into intracellular free calcium.

Objective To investigate the clinical value of proximal femoral nail antirotation ( PFNA) in treatment of intertrochanteric fractures.Methods From April 2007 to July 2009,112 patients with intertrochanteric fractures were treated by using PFNA.There were 34 males and 78 females,at mean age of 76 years.Of all,80 patients were with type 31-A2 fracture and 32 with type 31-A3 fractures according to AO classification.According to Singh index classification,there were 4 patients at grade Ⅰ,21 at grade Ⅱ,70 at grade Ⅲ and 15 at grade Ⅳ.The fracture was caused by low-energy injury in 97 patients and by high-energy injury in 15.The Salvati-Wilson score was used to evaluate the hip function postoperatively.Results Ninety patients received 12-24 months follow-up (average 18.6 months).The Salvati-Wilson score was (29.98 ± 5.18 ) points.The result was excellent in 41 patients,good in 40,fair in 6 and poor in 3,with excellenct rate of 90％.The introduction of the nail in operation was difficult in 22 patients,of which 3 patients suffered femoral cortex rupture.Displacement or separation of the fracture segments occurred in 34 patients and distal locking difficulty in nine during the screw blade tapping process.Local complications included hip pain in 21 patients,thigh pain in 4,apparent coxa vara in 2 and delayed healing in 7.There were no cutting-out or femoral shaft fractures no matter what type of Singh index was.The systemic complications included cardiovascular and cerebrovascular disease in one patient,pulmonary infection in four,deep vein embolism in one and perineum congestion or swelling in seventeen.Conclusion PFNA is effective in treating intertrochanteric fractures especially osteoporotic fractures,but delayed healing of the fractures and the mismatch between the intramedullary nail and the proximal femoral morphology remain to be addressed.

BACKGROUNDTo evaluate the activity and toxicity of paclitaxel as second-line treatment for advanced non-small cell lung cancer (NSCLC).

METHODSForty patients with recurrent advanced NSCLC were enrolled. Thirty-six patients were managed with regular regimen. Paclitaxel 135 mg/m², 3 h, on day 1; DDP 75 mg/m² or carboplatin 300-350 mg/m² on day 2. Four patients were managed with weekly regimen. Paclitaxel 60 mg/m²,3 h, on days 1,8,15; DDP 75 mg/m² on day 2. It was repeated every three or four weeks, up to two to four cycles.

RESULTSThirty-six cases were evaluated for response and 27 for survival. The objective response rate was 13.9% (5/36). At least one tumor-related symptom relief was observed in 21 patients (58.3%). The median survival duration was 26.4 weeks and 1-year survival rate was 8% (4/36). The main toxicities included myelosuppression, fatigue and myalgia-arthralgia neuropathy.

CONCLUSIONSPaclitaxel has advantage to be well-tolerated and improve tumor-related symptom. Further studies with standardization of dose and regimen will be needed to clarify its role in the second-line treatment.

BACKGROUNDTenidap is a liposoluble non-steroidal anti-inflammatory drug that is easily distributed in the central nervous system and also inhibits the production and activity of cyclooxygenase-2 (COX-2) and cytokines in vitro. This study aimed to evaluate the neuroprotective effect of tenidap in a pilocarpine rat model of temporal lobe epilepsy (TLE).

METHODSTenidap was administered daily at 10 mg/kg for 10 days following pilocarpine-induced status epilepticus (SE) in male Wistar rats after which prolonged generalized seizures resulted in TLE. After tenidap treatment, spontaneous recurrent seizures (SRSs) were recorded by video monitoring (for 7 hours per day for 14 days). The frequency and severity of the SRSs were observed. Histological and immunocytochemical analyses were used to evaluate the neuroprotective effect of tenidap and detect COX-2 expression, which may be associated with neuronal death.

RESULTSThere were 46.88 ± 10.70 survival neurons in tenidap-SE group, while there were 27.60 ± 5.18 survival neurons in saline-SE group at -2.4 mm field in the CA3 area. There were 37.75 ± 8.78 survival neurons in tenidap-SE group, while there were 33.40 ± 8.14 survival neurons in saline-SE group at -2.4 mm field in the CA1 area. Tenidap treatment significantly reduced neuronal damage in the CA3 area (P < 0.05) and slightly reduced damage in the CA1 area. Tenidap markedly inhibited COX-2 expression in the hippocampus, especially in the CA3 area.

CONCLUSIONTenidap conferred neuroprotection to the CA3 area in a pilocarpine-induced rat model of TLE by inhibiting COX-2 expression.

BACKGROUNDTo investigate the prevalence of anti-HEV among swine, sheep and chickens.

METHODSTotally 498 sera of swine, sheep and chickens collected from Xingjiang, Guangxi, Guangdong, Beijing and Hebei were detected for the anti-HEV by an enzyme linked immunoassay.

RESULTSThe anti-HEV positive rate of swine was 67.53%(104/154), in pigs between 4-5 months of age the rate was 100.00%(9/9) from Xingjiang. The rate in pigs under 3 months of age from Guangxi was 36.00%(9/25) and in pigs older than six months of age was 71.67% (86/120), respectively. The 108 sera of sheep collected from Xingjiang were all negative. The positive rate of chickens was only 1.27% (3/236). The anti-HEV prevalence rates of chickens from Luoding, Shenzhen, Liuzhou, Beijing and Hebei were 4.00%, 1.49%, 1.49%, 0, 0 respectively.

CONCLUSIONHEV infection does exist among swine and chickens. The anti-HEV prevalence of swine was the highest among domestic animals. The role of swine and chickens in transmission of HEV needs to be further studied.
