[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 observe the effect of wheat-grain moxibustion at "Dazhui" (GV 14), "Zusanli" (ST 36) and "Sanyinjiao" (SP 6) on Wnt/β-catenin signaling pathway in bone marrow cell in mice with bone marrow inhibition, and to explore the possible mechanism of wheat-grain moxibustion in treating bone marrow inhibition.
METHODS:
Forty-five SPF male CD1(ICR) mice were randomly divided into a blank group, a model group and a wheat-grain moxibustion group, 15 mice in each group. The bone marrow inhibition model was established by intraperitoneal injection of 80 mg/kg of cyclophosphamide (CTX). The mice in the wheat-grain moxibustion group were treated with wheat-grain moxibustion at "Dazhui" (GV 14), "Zusanli" (ST 36) and "Sanyinjiao" (SP 6), 3 moxa cones per acupoint, 30 s per moxa cone, once a day, for 7 consecutive days. The white blood cell count (WBC) was measured before modeling, before intervention and 3, 5 d and 7 d into intervention. After intervention, the general situation of mice was observed; the number of nucleated cells in bone marrow was detected; the serum levels of interleukin-3 (IL-3), interleukin-6 (IL-6) and granulocyte macrophage colony stimulating factor (GM-CSF) were measured by ELISA; the protein and mRNA expression of β-catenin, cyclinD1 and C-Myc in bone marrow cells was measured by Western blot and real-time PCR method.
RESULTS:
Compared with the blank group, the mice in the model group showed sluggish reaction, unstable gait, decreased body weight, and the WBC, number of nucleated cells in bone marrow as well as serum levels of IL-3, IL-6, GM-CSF were decreased (P<0.01), and the protein and mRNA expression of β-catenin, cyclinD1 and C-Myc was decreased (P<0.01). Compared with the model group, the mice in the wheat-grain moxibustion group showed better general condition, and WBC, the number of nucleated cells in bone marrow as well as serum levels of IL-3, IL-6, GM-CSF were increased (P<0.01, P<0.05), and the protein and mRNA expression of β-catenin, cyclinD1 and C-Myc was increased (P<0.05).
CONCLUSION
Wheat-grain moxibustion shows therapeutic effect on bone marrow inhibition, and its mechanism may be related to activating Wnt/β-catenin signaling pathway in bone marrow cells, improving bone medullary hematopoiesis microenvironment and promoting bone marrow cell proliferation.

Objective To describe the surgical technique and outcomes of arthroscopic reconstruction anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) and repair of the injured posteromedial complex (PMC) or posterolateral complex (PLC) structures of the knee joint in treatment of multiple ligaments injuries of knee. Methods From March 2005 to May 2007, 43 patients with multiple ligaments injuries of knee underwent arthroscopic reconstruction. Twenty-four patients were treated with arthroscopic reconstruction of combined ACL and PCL with allograft tendons and augmentation of PMC. The other 19 patients were treated with repair the PLC in addition to reconstruction of ACL and PCL. The International Knee Documentation Committee (IKDC) and Lysholm knee score were used for function evaluation. Results All patients were followed up for 24 to 48 months with an average of 33.10±9.65 months. The stability recovered when stress was applied to the knee at 0° and 20° of flexion. According to IKDC there was a significant improvement from severely abnormal (graded D) in 43 cases before surgery to normal (graded A) in 29 cases (67%), nearly normal (graded B) 11 cases (26%) and abnormal (graded C) 3 cases (7%) at follow-up. The average Lysholm score of the all cases were 46.7±4.2 and 89.6±2.8 before operation and at final follow-up, respectively (t=8.563, P<0.01).

OBJECTIVES:
To explore the homogeneity level of four different functional mRNA (PUM2, TAB2, Cx45 and CHRNA1) expressions in rats with skeletal muscle contusion.
METHODS:
The relative expressions of PUM2, TAB2, Cx45 and CHRNA1 mRNAs were detected by quantitative real-time reverse transcription-polymerase chain reaction (RT-qPCR). The coefficient of variation (CV) of the relative expressions for different individuals in each injury group was calculated. The extreme value of CV, cumulative variability, and CVCV were compared.
RESULTS:
A high CV of PUM2 and TAB2 mRNAs appeared on several different time points. However, the CV of Cx45 and CHRNA1 mRNAs was relatively low. The cumulative variability from high to low was PUM2, CHRNA1, TAB2 and Cx45 mRNAs. The relative expression of PUM2 mRNA was significantly higher than that of TAB2, Cx45 and CHRNA1 mRNAs ( P<0.05). There was no statistical significance (P>0.05) in the CVCV of the relative expression of TAB2, CHRNA1 and Cx45 mRNAs.
CONCLUSIONS
As the mRNAs involving in biological process regulation, PUM2 and CHRNA1 mRNAs show a lowest individual homogeneity of the relative expression followed by TAB2 mRNA. As the mRNAs participating in the composition of cellular structure, Cx45 and CHRNA1 mRNAs show a high individual homogeneity of the relative expressions. The functional classification should be considered for the screening of the mRNA indicators used for wound age estimation.

The medication rules of high frequency herb-pairs containing Codonopsis pilosula (Dangshen) were analyzed with data mining tools, and the molecular mechanisms of these herb-pairs on the gastrointestinal diseases were predicted with the network pharmacology. The R language association rules were used to mine the high frequency herb-pairs from TCM formulae containing Dangshen, and these herb-pairs would be screened out, which satisfied the following requirements with support ≥ 0.3 and confidence ≥ 0.9 at the same time. Using the Integrated Pharmacology Platform of Traditional Chinese Medicine (TCMIP) to predict the key core targets of the high frequency herb-pairs, the network of Chinese medicine-compound-target-pathway related to Dangshen were built to explore the preventing and treating molecular mechanism on gastrointestinal diseases. At last, the relation of the main active components from Dangshen and its herbal pairs with target proteins were validated by Systems Dock Web Site. The 185 formulae were selected from 543 formulae containing Dangshen, and 6 herbal pairs with Dangshen, which includes Angelica (Danggui), Licorice (Gancao), Atractylodes macrocephala (Baizhu), Poria cocos (Fuling), dried tangerine peel (Chenpi) and Astragalus membranaceus (Huangqi), were discovered with Apriori algorithm. The combination of 6 herbal pairs is similar to Bu Zhong Yi Qi Decoction; 6 herbal pairs with Dangshen were related to the target of POMC, OPRM1, CCR9 and HTR2C in TCMIP. The known targets (HTR2C, POMC, OPRM1, CCR9, OPRD1) and potential drug-targets (GNB1, GCK, SDHD, SLC25A2, DHRS4) for gastrointestinal diseases were predicted about the high frequency pairs with Dangshen. The results of GO enrichment analysis showed that the biological function was mainly located in the mitochondria and myelin sheath, and involved in the biological processes of three carboxylic acid cycle, platelet activation, and aspartic acid metabolism. KEGG pathway enrichment analysis showed that the main metabolic pathways related with Dangshen pairs involved amino acid metabolism, energy metabolism and endocrine metabolism. The prediction results showed many targets of the frequency herbal pairs with Dangshen preventing and treating gastrointestinal diseases were related with nerve cells. These herbal pairs could prevent and treat the gastrointestinal diseases through the neuroendocrine system and the brain gut axis.
