OBJECTIVETo study clinical results of the manual reduction in treatment.

METHODSFrom October 2010 to April 2013,39 children with Monteggia fracture associated with anterior interosseous nerve injury were treated by manual reduction and fixation on buckling rotation backward,including 17 females and 22 males with an average age of 6.3 years old ranging from 3.2 to 11 years old. Among them, 15 cases were on the right side and 24 cases on the left. The course of disease was 40 minutes to 8 days (averaged 1.5 days). There were 7 cases with skateboard injured, 13 cases with stumble injured, 11 cases with falling injured,8 cases with air bed injured. According to Bado classification, 13 cases were type II, 22 cases were type III, 4 cases were type IV.

RESULTSThe distal forefinger showed exercise normally in 34 cases at 3 weeks after treatment, and the patients restored normal activities at 6 weeks after treatment. All patients were follow-up from 54 days to 6 months (averaged 67 days. According to Mayo elbow functional evaluation standard,the scoring result was 19.62±1.35 in activity, 45.00 ± 0.00 in pain, 9.87 ± 0.80 in stability, 25.00±0.00 in strength, 99.49 ±1.92 in total. The outcome of all patients was excellent and good evaluation results.

CONCLUSIONIf the anterior interosseous nerve injury could be identified early and treated timely, patients could gradually restore reasonable function and recover with satisfactory results. Raising understanding of anterior interosseous nerve injury can effectively reduce misdiagnosis.

Objective To study the preliminary effect of sartorius iliac flap in repair of acetabulum defect for developmental dysplasia of the hip (DDH) in elder children.Methods We retrospectively studied 17 elder children with acetabulum defect in DDH at the age＞6 years old who received acetabular repair with sartorius bone flap in this hospital from 2014 to 2016.All patients with acetabulum defect in DDH were treated with open reduction in general anesthesia.Three-dimensional osteotomy under the femur rotor was conducted to correct the femoral anteversion and neck-shaft angle.According to the height of femoral head dislocation lines,femur tuberosity was shorten and fixied with steel plates,joint capsule was reconstructed,The iliac sartorius musculocutaneous flap was took to the upper edge of the acetabular to repair the acetabular defect.The lower extremities were treated with plaster for 6 to 8 weeks after surgery.The hip joint function was trained and the function was evaluated with Mckay's criteria.The hip joint morphological evaluation was performed with reference to Severin's X-ray standard.Results Seventeen patients were followed up for 6 to 29 months.Postoperative reduction of the femoral head was good,the head mortar inclusive was satisfactory;there were no wound infection and femoral head necrosis.According to Mckay's criteria,2 patients got excellent,13 good,and 2 fair,with the fineness ratio at 88.2％;According to Severin's critera:11 patients excellent.Conclusion The overturned sartorius iliac flap can repair acetabulum defect,promote bone healing,and effectively improve acetabulum to cover head of femur.

Background When limbal stem cell deficiency (LSCD) occurs,not only the limbal stem cells (LSCs) were damaged,but also the LSCs matrix microenvironment was under destruction.The treatment of LSCD include both replenishing of stem cells and restoration of microenvironment.So far,the method to improve the microenvironment of LSCD still exist limitation and urgently need to establish more appropriate microenvironment for the LSCs growth in vitro.Objective This study was to investigate whether the human bone marrow-derived mesenchymal stem cells (BMSCs) can be used as the ideal cells to repair limbal microenvironment and its possible mechanism of repairing limbal microenvironment during the human LSCs amplification in vitro as feeder cells.Methods BMSCs were cultured and passaged in vitro,and flow cytometry was used to assay the expressions of CD45,CD71,CD90,CD105 and HLA-DR and directionally induced BMSCs to the osteoblasts and adipocytes.BMSCs were treated using mitomycin C (MMC) to use as the feeder cells.LSCs were separately co-cultured with BMSCs,Swiss-3T3 feeder cells and free-feeder cells,and colony-forming efficiency (CFE) of the LSCs was compared among different co-cultured groups.LSCs were then cultured sequentially and identified by flow cytometry.Expression of cytokines in BMSCs was confirmed by reverse transcriptional polymerase chain reaction (RT-PCR).Results Cultured BMSCs showed a good homogeneity,with a lot of expressions of interstitial cell markers such as CD71,CD90,CD105 and less expressions of hematopoietic cell markers including CD45 and HLA-DR.After separately cocultured with feeder cells for 12 days,the CFE of the LSCs co-cultured with BMSCs,Swiss-3T3 and no feeder cells was 3.67％ ±0.58％,4.30％ ± 1.54％ and 0.20％ ±0.10％,showing a statistical significant difference among the three groups(F =15.420,P =0.040).There was no statistically significant difference in the C FE of the LSCs between the BMSCs feeder group and the Swiss-3T3 feeder cells group(P =0.456),between the BMSCs feeder group and the free-feeder cells group or the Swiss-3T3 co-culture group and the free-feeder cells group (P =0.005,0.002).LSCs presented with a positive response for ABCG2 antigen in the co-cultured with BMSCs group.Basic fibroblast growth factor(bFGF),stem cell factor (SCF) and N-cadherin(N-cad) were positively expressed in the BMSCs as feeder cells.Conclusions Human BMSCs-derived feeder cells can improve the growth of the stromal microenvironment of the LSCs and enhance their proliferation ability.Human BMSCs are suitable for engineering of epithelial sheets.

OBJECTIVETo explore the effect of Bushen Huoxue Decoction (BHD) on the orphan receptor (Nurr1) and tyrosine hydroxylase (TH) in the brain of rats with Parkinson's disease (PD).

METHODSOne hundred and twenty SD rats were divided into 100 in the model group and 20 in the normal control group, fifty-eight SD rats from the model group, established into PD model successfully by injuring their substantia nigra (SSN) with 6-hydroxydopamine, were divided equally into the model group and the test group, and they were treated with saline and BHD, respectively, for eight successive weeks. The change in the rats' behavior before and after treatment was observed by counting the cycles of rotation induced by apomorphine injection; the pathology of neurons, level of Nurr1 mRNA expression, and amount of TH positive cells in SSN were observed after treatment.

RESULTSThe rats' behavior was improved in the tested group significantly, the rotation cycle after treatment being 84.0 ± 20.0 cycles/40 min, which was significantly lower than that in the model group (377.0 ± 62.3 cycles/40 min, P<0.01). Besides, the Nurr1 mRNA expression and TH positive cell in the test group were 0.97 ± 0.15 and 49.40 ± 14.72, respectively, which were significantly higher than those in the model group, 0.22 ± 0.03 and 5.45 ± 2.58, respectively (all P<0.01).

CONCLUSIONBHD could treat PD by enhancing the Nurr1 mRNA expression, increasing the TH content in brain, and promoting the repairing of injured neuron in cerebral SSN.

Fuzi is a medicine used for rescuing from collapse by restoring yang as well as a famous toxic traditional Chinese medicine. In order to ensure the efficacy and safe medication, Fuzi has mostly been applied after being processed. There have been different Fuzi processing methods recorded by doctors of previous generations. Besides, there have also been differences in Fuzi processing methods recorded in modern pharmacopeia and ancient medical books. In this study, the authors traced back to medical books between the Han Dynasty and the period of Republic of China, and summarized Fuzi processing methods collected in ancient and modern literatures. According to the results, Fuzi processing methods and using methods have changed along with the evolution of dynasties, with differences in ancient and modern processing methods. Before the Tang Dynasty, Fuzi had been mostly processed and soaked. From Tang to Ming Dynasties, Fuzi had been mostly processed, soaked and stir-fried. During the Qing Dynasty, Fuzi had been mostly soaked and boiled. In the modem times, Fuzi is mostly processed by being boiled and soaked. Before the Tang Dynasty, a whole piece of Fuzi herbs or their fragments had been applied in medicines; Whereas their fragments are primarily used in the modern times. Because different processing methods have great impacts on the toxicity of Fuzi, it is suggested to study Fuzi processing methods.

The fruit of Pandanus tectorius (PTF) has a long history of use as a folk medicine to treat hyperlipidemia in Hainan province, South China. Our previous studies have shown that the n-butanol extract of PTF is rich in caffeoylquinic acids and has an adequate therapeutic effect on dyslipidemic animals induced by high-fat diet. In this work, seven caffeoylquinic acids isolated from PTF were screened for the lipid-lowering activity in HepG2 hepatoma cells. Oil-Red O staining, microscopy and intracellular triglyceride (TG) and total cholesterol (TC) quantification showed that 3-O-caffeoylquinic acid (3-CQA), 3, 5-di-O-caffeoylquinic acid (3,5-CQA), and 3,4,5-tri-O-caffeoylquinic acid (3,4,5-CQA) significantly inhibited lipid accumulation induced by oleic acid and decreased intracellular levels of TC and TG in a dose-dependent manner. These three caffeoylquinic acids showed no significant cytotoxicity at concentrations of 1 -50 μmol x L(-1) as determined by MTT assay. Realtime quantitative PCR revealed that 3-CQA and 3, 5-CQA significantly increased the expression of lipid oxidation-related genes PPARα, CPT-1 and ACOX1 while 3-CQA, 3, 5-CQA and 3,4,5-CQA decreased the expression of lipogenic genes SREBP-1c, SREBP-2, HMGR, ACC, FAS. Overall, 3-CQA, 3, 5-CQA and 3, 4, 5-CQA may be the principal hypolipidemic components in PTF which can decrease intracellular lipid accumulation through up-regulating the expression of lipid oxidative genes and down-regulating the expression of lipogenic genes.
