Objective To introduce the Bernese periacetabular osteotomy through ilioinguinal approach for the treatment of adult acetabular dysplasia. Methods From October 1997 to April 2001, 51 patients(53 hips) with acetabular dysplasia were operated upon with Bernese periacetabular osteotomies through ilioinguinal approach. The mean age of the patients at the time of surgery was 30.6 years(range, 13-48 years). Male∶female= 1∶10. Preoperatively, the average duration of the symptoms was 3.4 years(3 months to 15 years), the range of motion(ROM) of the hip was normal in most patients. Average CE angle was 1.1?(?15?-15?); the Tonnis osteoarthritis grade was Ⅰto Ⅱ. Fifty three percent of the hips had Shentons line broken. Results Twenty four hips had 12 to 38 months followed up. Most patients were pain free; the hip ROM remained normal. Harris hip score increased from 79.8(64-83) pre operatively to 93.8(75-100) post operatively. CE angle increased to 40?(20?to 60?). Shentons line broken rate decreased to 33%. The complications include: 1 femoral nerve damage, 1 bladder malfunction and 2 skin incision hernia. Conclusion The Bernese periacetabular osteotomy through ilioinguinal approach is a safe and efficient procedure for the treatment of adult acetabular dysplasia. The deformities could be easily corrected, the anatomic relations could be restored nicely, the pelvic ring and the abductor muscles are reserved. The post operative recovery is fast, and it is efficient to prevent the development of osteoarthritis of the hip joint.

Abstract Objective:FSM-2117 and FS-5416 are two bivalent hybrid strains of S.flexneri and S.sonnei, constructed by this laboratory-The FS-5416 expresses four invassive plasmid antigens(IpaA、IpaB、IpaC and IpaD) and has a good contact heamolysis activity(CHA+ ), butFSM-2117 hasn' t. To observe the immunogenicity of Shigelk vaccines through three different mucosal administration rout, the changes of ASCin the spleen and Peyer's patch(PP) , mesenteric lymph nodes(MLN) lymphocytes are detected.Methods:BALB/c mice were divided intothree groups, 20 mice per group. Mice were immunized respectively with the Ipa+ or Ipa- vaccines(4 x 10~7 CFU) three times with an intervalof two weeks by intranasal、intragastric or intraintestinal administration routs. The spleen , PP , MLN lymphocytes were isolated of seventh dayat random after immunization. An BA-EIISASPOT was done to account the numbers of ASC.Results:The numbers of SIgA and SIgG ASC ofspleen , PP , MLN lymphocytes of intranasal and intraintestinal group were significantly increased . Significant difference were only observed inthe number of spleen lymphocytes SIgA and SIgG ASC of intranasal group between Ipa+ and Ipa- . Conclusion:Two bivalent Shigelk vaccinescan induce spleen and GALT immunity reaction by nasal or small intestinal mucosal in a low dosage compared with intragastric rout (about 1/20). Ipa can significantly increased the number of spleen lymphocytes SIgA and SIgG ASC of intranasal group.

Objective To evaluate the value of 18F-FDG PET/CT in assessing radiosensitivity enhancement by irisquinone (IR) on rabbit xenografted VX2 lung tumor models.Methods Twenty-four tumor-beating rabbits were randomly divided into 3 groups (8 rabbits/group):group A with radiotherapy alone,group B with combined radiotherapy and IR,and group C without radiotherapy (the control group).18F-FDG PET/CT imaging was performed before radiotherapy and 24 h and one week after radiotherapy.The tumor SUVmax on delayed imaging was calculated in all rabbits.Two rabbits in each group were sacrificed after PET/CT imaging.HE staining was used to assess the differences in cancer cells among groups.Paired t test,one-way analysis of variance and Kaplan-Meier analysis were performed to analyze the data using SPSS 13.0.Results Before radiotherapy,the tumor SUVmax of all the 24 rabbits on standard and delayed imaging were 2.200 ± 0.761 and 3.162 ± 0.833 (t =-5.582,P ＜ 0.01).At 24 h post-radiotherapy,the delayed SUVmax of groups A,B and C were 2.614 ± 0.654,2.349 ± 0.869 and 5.663 ± 1.144,respectively.The differences between pre-radiotherapy and 24 h post-radiotherapy were statistically significant in all three groups (t =2.527,3.620,11.011,all P ＜0.05).One week after radiotherapy,the delayed SUVmax of groups A,B and C were 3.625 ± 1.064,3.058 ±0.850 and 7.424 ± 1.751,respectively.The differences among groups A,B and C were statistically significant (tA∶ B =2.652,tA∶C =3.799,tB∶C =4.366,all P ＜0.05).The cancer cells of group B were fewer than those of groups A and C by pathological findings,which was consistent with 18F-FDG PET/CT results.The survival times of groups A,B and C were (62.375 ±4.534),(69.000 ±4.660) and (54.125 ±5.276) d,respectively.Kaplan-Meier survival curves revealed better survival of group B as compared to groups A and C,respectively (Log-rank,x2 =7.355,16.943,both P ＜ 0.01).Conclusion 18 F-FDG PET/CT is able to evaluate the effect of irisquinone on tumor radiosensitivity enhancement.

Objective To evaluate the reliability and validity of the Chinese-version Successful Aging Inventory (C-SAI).Methods The C-SAI was translated according to the Brislin translation model,and its reliability and validity was tested in 181 old adults.Results The content validity index for the scale (S-CVI/Ave) was 0.975.Five factors were extracted by principal components analysis which contributed 58.035％ to the variance.The Cronbach α and split-half reliability was respectively 0.832 and 0.871 for the total scale.Conclusions The C-SAI has good psychometric quality and can be used as a measurement tool for the successful aging.

Objective To observe the clinical effect on cervicogenic headache (CEH) of pulsed radiofrequency stimulation (PRF) applied to the C2 dorsal root ganglion combined with nerve block.Methods A total of 78 cases diagnosed as CEH were randomly divided into a combined treatment group,a PRF treatment group and a nerve block group.The combined treatment group was given both PRF applied to the C2 dorsal root ganglion and blocking therapy.The other two groups were given only one treatment or the other.All the treatments were once weekly for 3 weeks.Before treatment and 1,3 and 6 months after treatment,all of the patients' headaches were evaluated using a visual analogue scale (VAS).Results At 1,3 and 6 months after treatment,the average VAS scores of all three groups had decreased significantly.The VAS ratings dropped the most in the combined treatment group,followed by the PRF group and then the nerve block group.All the intergroup differences were statistically significant.The combined treatment group's cure rate (88％) was significantly better than that of the PRF group (81％),which was significantly better than that of the nerve block group (54％).Conclusion Combining PRF applied to the C2dorsal root ganglion with nerve block therapy has a synergistic effect on CEH.The curative effect of the combined treatment was better than either PRF or blocking alone.

This study is to observe the protection of gross saponins of Tribulus terrestris (GSTT) on cardiocytes impaired by adriamycin (ADR) and approach its mechanism of action. Cardiocytes of neonate rat were cultivated for 72 hours and divided into normal control group, model (ADR 2 mg?L-1) group, and GSTT (100, 30, and 10 mg?L-1) groups. MTT colorimetric method was deployed to detect cardiocyte survival rate, activities of CK, LDH, AST, SOD, MDA and NO were detected, and apoptosis was detected with flow cytometry. Effect of GSTT on caspase-3 was detected with Western blotting. Compared with control group, contents of CK, LDH, AST, MDA and NO were increased, and activity of SOD was reduced (P

Objective To compare the clinical outcomes of patients who underwent remnant-preserved anterior cruciate ligament (ACL) reconstruction with those who underwent conventional ACL reconstruction (ACLR).Methods From January 2010 to October 2012,93 eligible patients suffered from ACL injuries were randomly allocated into remnant-preserved group (ACLR with remnant preservation;n=48;Male/Female=34/14;Left/Right=25/23) and conventional group (ACLR without remnant preservation;n=45;Male/Female=33/12;Left/Right=22/23).The mean age of patients,time from injury to surgery,rates of combined meniscal injuries,and medial collateral ligament injury all showed no significant difference between the two groups preoperatively.All the patients underwent ACL reconstruction using 4-strand hamstring autografts.The postoperative assessments included knee functional scales (IKDC grade classification and Lysholm score),stability examinations (Lachman,pivot-shift,and KT-1000 arthometer),proprioceptive evaluations,and second-look arthroscopy.Results The average follow-up time was 25.4 months for the remnant-preserved group and 25.2 months for the conventional group.For IKDC grade classification,there were 32 patients with grade A,9 with grade B,1 with grade C in remnant-preserved group,whereas 30 with grade A,8 with grade B,2 with grade C in conventional group,which showed no significant difference between the two groups.Moreover,the Lysholm score (95.9±5.2 vs.95.4±1.7),Lachman test,pivot-shift test,KT-1000 arthometer (1.1±1.2 mm vs.1.2±0.9 mm),proprioceptive evaluations (joint position sense:3.6°± 1.8° vs.3.9°±2.2°) all showed no significant differences between the two groups.Additionally,the synovial coverage of grafted tendon under second-look arthroscopy was categorized as grade A in 11,grade B in 6,grade C in 2,grade D in 2 in remnant-preserved group,whereas grade A in 10,grade B in 5,grade C in 2,and grade D in 2 in conventional group,which still showed no significant difference.Conclusion In terms of the knee functional scales,stability examinations,joint position sense and graft synovial coverage,remnant-preserved ACLR group showed no superiority to the conventional ACLR group.

Objective To evaluate the feasibility of real time elastosonography in estimating the characteristic of nodules in resected hepatocirrhosis specimens.Methods Thirty-eight reseeted hepatocirrhosis specimens underwent elastosonography.The nodules that have drawn attention were performed elastosonography through rhythmic pressing and releasing the probe by manual form on the liver.The hepatic strain on the region of interest was shown by chromatic scale.To compare nodules rigidity with surrounding hepatic tissues, hepatocirrhosis nodules were classified into hard nodules, medium rigidity nodules, mixture of hard and soft nodules, and soft nodules.All nodules were confirmed by pathology.Results Forty-four nodules of 38 hepatocirrhosis exemplar received real time elastosonography.Of 44 nodules, hard nodules were 18,of which 12 (66.7%) were hepatoeellular carcinomas, 2 (11.1%) were dysplasia nodules, 4 (22.2%) were regenerative nodules.Medium rigidity nodules were 7,all were regenerative nodules.Mixture of hard and soft nodules were 11, of which 8 (72.7%) were hepatocellular carcinomas, including 4 accompanied necrotic tissue, 1 (9.1%) was dysplasia nodules accompanied necrotic tissue, the other 2 (18.2%) were regenerative nodules accompanied necrotic tissue.And soft nodules were 8, of which 4(50.0%) were necrotic nodules, 1 (12.5%) was dysplasia nodules accompanied canceration, 1 (12.5%) was hepatocellular carcinoma,2(25.0 %) were regenerative nodules.Conclusions Real time elastosonography can effectively evaluate the comparative rigidity on hepatoeirrhosis nodules,and thus may have potential usefulness on estimating the characteristic of hepatocirrhosis nodules.
