[Objective]To discuss the outcome of acetabular protrusion after total hip arthroplasty. [Method]Fifteen patients(M=7,F=9) having painful acetabular protrusion received total hip arthroplasty with reinforcement of the acetabulum with bone grafts(autogenous or allogeneous bone).The results were reported at 1~4 years(mean,3 years) of follow-up.Of the 15 cases,5 were mild protrusion and 10 were moderate protrusion.The Harris hip-rating and radiographs were taken pre-and postoperatively. [Result]The average Harris hip-rating was improved from 45 points(range,39~60 points) preoperatively to 85 points(range,70~100 points) postoperatively.The average preoperative protrusion of the femoral head medial to the Kohler line was 8.8 mm(6~18 mm).The average postoperative placement of the prosthetic femoral head was 10 mm(6~13 mm) lateral to the Kohler line.None acetabulum prothesis failure or bone grafts absorption was seen.The grafts were well incorporated on radiograms in all patients one year after operation by radiographs. [Conclusion]Good results can be obtained in hips with acetabular protrusion after reconstructed with autogeneous or allogeneous bone grafting and total hip arthroplasty.

Objective To analyze the etiology of diabetes ketoacidosis(DKA) in children with type 1 diabetes.Methods Totally 850 person-time of type 1 diabetes children in recent 20 years in our hospital were selected as studied subjects. Two hundred and twenty-five person-time of them were hospitalized because of DKA.Fifty-six cases (131 person-time) were due to recurrent DKA.These patients were classified into 2 groups according to onset time: group 1(diagnosed from 1982 to 1991) and group 2(diagnosed from 1992 to 2001).Results The analysis of recurrent DKA suggested that 71.8 % of them was due to infection, 20.4 % of them did not obey diabetic diet and 9.2 % of them discontinued insulin injection. The etiology of DKA showed no difference in two groups. The number of recurrent DKA in two groups was significantly different (P

Objective To evaluate the associations of human leukocyte antigen(HLA)-DQ gene with autoimmune polyglandular syndrome(APS),type 1 diabetic mellitus(T1DM) and autoimmune thyroid disease(AITD).Methods Fifteen cases of APS,29 cases of T1DM and 40 cases of AITD were selected as research subjects,while 27 healthy children were selected as controls.The DQA1 and DQB1 alleles were determined by polymerase chain reaction(PCR) and sequence-based typing method.The difference of their frequency in children and adolescents was analyzed.Results Compared with controls,APS and T1DM patients had increased frequency of subjects with DQA1*0301,0501(all P

Objective To investigate the expression of growth arrest-specific protein 6 (Gas6) in the placenta and decidua tissues and its relationship with the pathogenesis of preeclampsia. Methods All the patients were recruited in Qilu Hospital of Shangdong University from October 2013 to June 2014. Among them, thirty-two women with early-onset severe preeclampsia who received cesarean section were assigned to the preeclampsia group, and thirty healthy pregnant women who received cesarean section were defined as the control group. Blood glucose, blood lipids, platelet count, D-dimer levels and other clinical indicators of the two groups were detected. Immunohistochemistry of SP was conducted to identify the localization of Gas6 protein in the placenta and decidua tissues. And reverse transcription (RT)-PCR was performed for quantitative analysis of Gas6 RNA expression in placentas. The correlations between placental Gas6 mRNA levels with clinical indicators were analyzed. Results (1) The gestational age at delivery, blood pressure, serum albumin, platelet count and birth weight of fetuses showed statistically significant differences between the two groups(P<0.05). (2) The Gas6 protein expressed in the cytoplasm and nucleus of the syncytiotrophoblasts and decidual cells in the placenta and decidual tissues of the two groups. (3) The Gas6 mRNA expression elevated significantly in the placenta of preeclampsia group (0.60 ± 0.38) when compared to that of the control group (0.34±0.22;P<0.05). (4) The expression of Gas6 mRNA was positively related with body mass index, diastolic blood pressure, systolic blood pressure, free fatty acids and creatinine (P<0.05), while it was negatively associated with serum albumin(P<0.05). Conclusion The high expression of Gas6 in the placenta and decidua tissues may be related to the pathogenesis of severe preeclampsia.

Objective To investigate the expression of interleukin-37 (IL-37) in placenta tissue and its relationship with the pathogenesis of severe preeclampsia. Methods All the patients were recruited in Qilu Hospital of Shangdong University from November 2012 to November 2013. Among them, thirty patients with severe preeclampsia were assigned to the preeclampsia group, and thirty-one healthy pregnant women were assigned to the control group. Immunohistochemistry of SP was used to detect the IL-37 protein expression in placenta tissue of the two groups. The expression level of IL-37 in placenta tissue of the two groups was detected by western blot. Besides, reverse transcription(RT)-PCR was used to detect the expression of IL-37 mRNA. The correlation between the expression of IL-37 mRNA and the delivery gestational age, body mass index(BMI)was analyzed. Results (1) IL-37 were detected in the placenta of both the preeclampsia group and the control group, and the expression site mainly located in the syncytiotrophoblast, with a small amount in cytotrophoblast.(2)The expression levels of IL-37 protein in the preeclampsia group and the control group were 0.59 ± 0.39 and 0.88 ± 0.22, respectively. The IL-37 mRNA levels in the preeclampsia group and the control group were 0.55 ± 0.17 and 1.11 ± 0.21, respectively. Both decreased significantly when compared to the control group (P<0.05). (3) Significant correlation between the expression of IL-37 mRNA and the delivery gestational weeks(r=0.209, P>0.05) was seen neither in the preeclampsia group nor in the control group(r=-0.053, P>0.05). In the severe preeclampsia group, the pregnant women′s BMI had no significant correlation with IL-37 mRNA expression of placenta tissue(r=0.102, P>0.05), neither did the control group(r=-0.115, P>0.05). Conclusion IL-37 expression is significantly lower in severe preeclampsia placenta tissue than that in the normal pregnant women, which may play a protective role in the course of severe preeclampsia.

OBJECTIVE:To study the effects of the compatibility of medicinal materials on the content of icariin in Gushuling granules formula. METHODS:The effects of the compatibility of medicinal materials on the content of icariin was investigated by orthogonal design with the compatibility of Astragalus membranaceus,Achyranthes bidentata and Concha ostreae as factors,using the content of icariin in decoction as index. The pH of mixture of Epimedium brevicornu and A. membranaceus,and the content of icariin in precipitation were determined. RESULTS:The effects of the compatibility of A. membranaceus on the content of icariin had statistical significance (P<0.05);the compatibility of A. bidentata and C. ostreae had no statistical significance (P>0.05);the interactions between two medicinal materials had not been found;the pH of the mixtures had no significant difference;the com-patibility of E. brevicornu and A. membranaceus produced precipitation,and the content of icariin in precipitation increased. CON-CLUSIONS:The compatibility of E. brevicornu and A. membranaceus can produce precipitation,so as to decrease the content of icariin in decoction,which is not influenced by pH value of decoction.

Objective To evaluate a combination of interventional treatment and surgical exploration for acute lower limb ischemic disease.Methods We reviewed 42 cases admitted from July 2007 to January 2010,all patients complained pain,paralysis,pulselessness,pallor and paresthesia.After Fogarty thrombectomy angiography was taken in DSA room.Patients with angiostenosis greater than 50％ were then managed by interventional treatment(CDT,PTA,Stenting).Results Lives were saved in all patients,40 lower limbs were saved,and 2 patients received below knee amputation.The amputation rate was 4.76％.Dorsal or(and)posterior tibial artery of foot was felt in 33 patients,symptoms significantly improved.The other 7 patients still had painful and paralysis on the diseased limb.Conclusions The interventional treatment and surgical operation in acute lower limb ischemic disease is safe and result is satisfactory,which can improve the long-term patency and salvage rate of the lower limb.

Objective To evaluate balloon angioplasty and stenting of the hepatic veins for the treatment of Budd-Chiari syndrome with long segmental inferior vena cava (IVC).Methods The hepatic veins were evaluated by colour Doppler,CT or MR.Epidiaphragmatic inferior vena cavography was performed to locate the stenused opening of the hepatic veins,in case of membrane occlusion of the hepatic veins,a puncture was attempted with Rups100 needle and then balloon dilation of the hepatic veins and stents implantation was carried out.Results In 40 cases of long segmental inferior vena cava ( IVC ) occlusive Budd-Chiari syndrome,membranous obstruction of the hepatic veins was found in 5 cases and short-segmental occlusion in 24 cases.28 cases were successfully treated with balloon dilation and stents implantation,including percutaneous transluminal angioplasty(PTA) of hepatic vein in 5 cases,and stent implantation in 23 cases,puncture procedure was failed in 1 case.Postoperative follow-up was made in 26 cases from 6 to 62 months ( mean,24.0 ± 1.3 months ).Symptoms recurred in 6 cases.Hepatic vein restenosis or occlusion were observed using color Doppler ultrasound in 6 cases.Conclusions Most lesions in hepatic veins were membranous obstruction or short-segmental occlusion among patients with long-segmental occlusion of IVC.Balloon angioplasty and stenting of hepatic veins for long segmental IVC occlusive Budd-Chiari syndrome through jugular vein can relieve hepatic venous obstruction and relieve portal hypertension.

Objective To evaluate the efficacy of endovascular interventional treatment for infrapopliteal arterial ischemic diseases. Methods Sixty patients(65 limbs)of infrapopliteal arterial isehernia of the lower extremities received pereutancotm transluminal angioplasty(PTA)and/or stents implantation from November 2004 to July 2007.The symptoms,changes of ankle/brachial index(ABI),limb salvage rate and immediate patent rate were observed.

Conclusions Endovascular interventional treatment for infrapopliteal arterial ischemic disease is safe and effective.

ObjectiveTo investigate the distribution of Kashin-Beck disease(KBD) in Tibet, and assess the disease status. Methods Between 2007 and 2008, a survey was done on KBDepidemiology which was carried out in four prefectures of 26 counties according to the east, south, west, north and center in Nakchu,Lhoca, Nyingtri and Shigatse districts of Tibet, with towns and villages as baseline survey points. According to the KBD e survey scheme, KBD clinical examination for adults was also carried out and at the same time clinical and right hand anteroposterior X-ray examinations were given to children aged 4 - 13. The partition of endemic area was based on the criteria of national standards for Kashin-Beck disease diagnoses《GB 16395-1996》. Slight KBD area:clinical prevalence of Kashin-Beck disease grade Ⅰ and above was less than 10％ or X-ray detection rate ＜ 10％ of children; the moderate prevalent KBD area: clinical prevalence of Kashin-Beck disease grade Ⅰ and above was between 10％ and 20％ or X-ray detection rate was between 10％ and 30％ of children; severe KBD area: clinical prevalence of KBD grade Ⅰ and above was more than 20％ or X-ray detection rate was higher than 30％ of children.ResultsA total of 108 townships of 26 counties were surveyed, 14 686 adults were clinically examined, cases detection of grade Ⅰ and above were 637 people, the prevalence was 4.34％, and no case of grade Ⅲ was detected.Of 5769 children's right anteroposterior X-ray film, 102 were detected positive; the prevalence rate was 1.77％.Metaphysis was affected in most of the child cases, which accounting for 89.2％ (91/102). Amongst all the counties, there were 10 counties, clinical detection rate of adult KBD was 0, and children's X-ray detection rate of KBD was also 0. In 1 county the clinical prevalence rate for adults KBD was 0 and X-ray detection rate for children was 3.66(7/191 ). In 12 counties the clinical prevalence rate for adults KBD was between 1.03％ and 7.54％, X-ray detection rate for children was between 0 and 7.76％, amongst all these counties surveyed there were 5 counties,the detection rate for children was 0. In 3 counties the clinical prevalence rate for adult KBD was between 10.69％and 13.88％, the X-ray detection rate for children was between 5.31％ and 7.76％. Conclusions According to the criteria for diagnoses of KBD, within the 26 counties surveyed, 10 counties are non-endemic areas, 13 counties are slight endemic areas, 3 counties are medium endemic areas. So far, KBD is prevalent in 52 counties of 7 prefectures (cities) in Tibet, the disease is widely distributed, the situation is still severe, and there is a need to continue to strengthen KBD surveillance.
