[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 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 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.

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.

OBJECTIVETo evaluate preliminarily the efficacy on functional constipation treated with electroacupuncture of different acupoint prescriptions.

METHODSOne hundred and four patients were randomized into a front-mu and back-shu points group (19 cases), a he-sea points group (34 cases), a he-sea, front-mu and back-shu points group (26 cases) and a western medication control group (25 cases). In the front-mu and back-shu points group, electroacupuncture was applied at bilateral Tianshu (ST 25) and Dachangshu (BL 25). In the he-sea points group, electroacupuncture was applied at bilateral Quchi (LI 11) and Shangjuxu (ST 37). In the he-sea, front-mu and back-shu points group, electroacupuncture was applied at unilateral Tianshu (ST 25), Dachangshu (BL 25), Quchi (LI 11) and Shangjuxu (ST 37). In the three groups above, the treatment was given 5 times a week in the first two weeks and 3 times a week in the next two weeks. In the western medication control group, mosapride citrate tablets were prescribed for oral administration, 1 table (5 mg) each time, 3 times a day, continuously for 4 weeks. The period of research was 9 weeks, including 1 week for baseline evaluation, 4 weeks for treatment and 4 weeks for follow-up. The weekly defecation frequency was taken as primary index, while the defecation difficulty and life quality score were taken as the secondary indices for the efficacy evaluation after treatment and in follow-up.

RESULTSAccording to the intention-to-treat (ITT) analytic principle, 104 cases were all enrolled in the final analysis. (1) After treatment, the weekly frequency of defecation was all increased significantly in the four groups (P < 0.05, P < 0.01). The efficacy of the three electroacupuncture groups was similar to that of western medication control group (P > 0.05). In follow-up, the increasing effect on the weekly frequency of defecation was maintained in the he-sea points group (P < 0.01), superior to the front-mu and back-shu points group and the western medication control group (P < 0.05, P < 0.01); the weekly frequency of defecation was not improved in the rest three groups (P > 0.05). (2) After treatment, defecation difficulty was relieved in the he-sea points group, the he-sea, front-mu and back-shu points group and the western medication control group (P < 0.05, P < 0.01). In follow-up, the improvements were still significant in the he-sea points group and the he-sea, front-mu and back-shu points group (both P < 0.01). (3) After treatment, the life quality score was significantly improved in the patients of the he-sea points group (P < 0.05). The difference was not significant in the rest three groups as compared with that before treatment (all P > 0.05).

CONCLUSIONThe weekly frequency of defecation is increased effectively after treatment in the three electroacupuncture groups and the efficacy is similar to mosapride citrate tablets. The bilateral Quchi (LI 11) and Shangjuxu (ST 37) in he-sea acupoints increase significantly the weekly frequency of defecation, relieve defecation difficulty and improve life quality. Acupuncture efficacy is sustained for 4 weeks. This acupoints prescription is the best in the treatment of functional constipation.

Objective To investigate the changes in the serum level of vascular endothelial growth factor (VEGF) in experimental Wistar rats with hepatic alveolar echinococcosis (HAE) after hepatic arterial infusion (HAI) of bevacizumab treatment, and to discuss the efficacy of HAI of bevacizumab for hepatic alveolar echinococcosis. Methods Forty Wistar rats with successfully established HAE were randomly and equally divided into two groups with 20 rats in each group: the control group and the study group. Hepatic arterial infusion of saline was performed in the rats of the control group , while hepatic arterial infusion of bevacizumab was carried out in the rats of the study group. Before and 7, 14, 21 and 28 days after the treatment peripheral blood samples were collected from the tail vein, and the serum levels of VEGF, apartate aminotransferase (AST) and alanine aminotransferase (ALT) were determined by the quantitative sandwich enzyme-linked immunosorbent assay (ELISA). All the rats were sacrificed 28 days after the treatment. HAE samples were examined to evaluate the effect of bevacizumab on HAE lesions. Results Seven days after hepatic arterial infusion of bevacizumab, serum VEGF expression level in the study group became gradually decreased, and the difference was statistically significant when compared with the preoperative level or with that in the control group (P = 0.019). Fourteen days after the treatment, the serum VEGF expression level kept going down to its lowest point, and the difference in serum VEGF expression level was statistically significant when compared with the preoperative level (P < 0.01). Twenty-one days after the treatment, serum VEGF expression level started to rise and it returned to normal level in 28 days after the treatment. In the control group no significant changes in serum VEGF expression levels was observed after hepatic arterial injection of saline (P > 0.05). Conclusion In treating hepatic alveolar echinococcosis, hepatic arterial infusion of bevacizumab has certain inhibitory effect on angiogenesis. This therapy is safe and effective.
