Objective To study the feasibility and indication of liver injury in children treated nonoperatively.Methods Ninteen(cases) with liver injury who underwent nonoperative management(NOM) were analyzed retrospectively.Patients with obvious trauma were reviewed.The main cause of trauma was due to traffic accident.Eleven cases(57.9%) had subcapsular hematoma and 8 cases(42.1%)had intrapararenchymatous hematoma.The treatment procedure included blood transfusion,hemostasis and monitoring the hemodynamic parameters.Results Seventeen cases(89.5%)were cured nonoperatively;2 cases underwent the operation later.Followed up for 10-24 months,patients were well recovered.Conclusions Most of cases with liver injury in children can be cured by NOM due to the physicalogical and anatomic features of children.During treatment,it is very important for the doctors to observe the vital signs closely,and(mana)-ge the combined injuries effectively and take regular imaging measurement.

Objective To assess the association between glutathione S-transferase T1 (GSTT1 )gene and the susceptibility of colorectal cancer among Chinese population.Methods Clinical controlled trials of the association between GSTT1 and the susceptibility of colorectal cancer among Chinese population were searched in PubMed,EMBase,Cochrane Library,China Biology Medicine disc,VIP database,China National Knowledge Infrastructure and Wanfang database.According to the inclusion and exclusion criteria,data extraction and quali-ty assessment were done by two researchers independently.Outcomes were pooled with RevMan 5.1 .Results 326 studies were found and 10 clinical controlled trails including 2 983 cases of colorectal cancer and 4 386 cases of healthy objects were included in this analysis.The results of Meta-analysis showed that the lack of GSTT1 gene is associated with colorectal cancer susceptibility (RR =1 .11 ,95%CI:1 .06-1 .17,Z =4.26,P <0.000 1 ). Conclusion The loss of GSTT1 increase the risk of colorectal cancer among Chinese population.

OBJECTIVE: To study the expressions of focal adhesion kinase (FAK) and phospho-FAK( p-FAK) during skin incised wound healing and the applicability of time-dependent expressions of FAK and p-FAK. METHODS: The expression of FAK and p-FAK in cutaneous incised wound in mouse were investigated by immunohistochmeistry and Western blotting. RESULTS: FAK and p-FAK expression were detected in polymorphonuclear cells (PMNs) in the wound and adjacent regions 3 hours post-injury. The expressions of FAK and p-FAK were detected in a large number of infiltrating PMNs and some of mononuclear cells (MNCs) from 6 to 24 hours after injury. The MNCs and fibroblastic cells (FBCs) accounted for most part of the FAK and p-FAK positive cells from 3 to 14 days after injury. The numbers of FAK-positive cells increased continuously, reaching a peak at post-injury day 3, and then started to decrease from post-injury day 5 to 14. The changes of p-FAK-positive cells were similar to that of the FAKs, and reached a peak at 12 hours after injury. CONCLUSION Both FAK and p-FAK displayed a time-dependent expression during skin incised wound healing in mouse, with p-FAK being superior to FAK. Both FAK and p-FAK may potentially be used as new markers for determination of the wound interval.

Objective To evaluate the efficacy of moxifloxacin-based triple therapy combined with rebamipide for Helicobacter pylori (Hp) eradication in type 2 diabetic patients.Methods Two-hundred age and sex matched type 2 diabetic patients with Hp infection and accompanied by gastrointestinal symptoms were assigned into rebamipide group (n =100) and placebo group (n =100).Both groups received moxifloxacin-based triple therapy for 10 d to eradicate Hp.Rebamipide was administrated in rebamipide group and placebo was administrated in placebo group for 30 d.All patients proceeded 14C-urea breath test (14C-UBT) hefore and 7-8 weeks after eradication therapy.The blood sugar indices,gastrointestinal symptom scores and Hp eradication rates were measured and compared.Those who had gained successful Hp eradication in both groups proceeded 14 C-UBT again 12 months after eradication therapy,and the re-infection rates of both groups were compared.Results There were no significant differences in the average fasting glucose,postprandial glucose and HbAlc levels between the rebamipide group and the placebo group before and after therapy (P ＞ 0.05),the gastrointestinal symptoms of the rebamipide group were improved more markedly than those of the placebo group after therapy (Rome Ⅲ Criteria,2.1 ± 0.9 vs.4.4 ± 0.7,P ＜ 0.01).The Hp eradication rate with both intention-to-treat (ITT) and per protocol (PP) analysis of the rebamipide group were higher than that of the placebo group [86.0％ (86/100) vs.73.0％ (73/100),P ＜ 0.05 and 92.5％ (86/93) vs.76.8％ (73/95),P ＜ 0.01].The re-infection rates with both ITT and PP analysis of those who had successful eradication in rebamipide group were lower than that in placebo group [19.8％ (17/86) vs.35.6％ (26/73),P＜0.05and20.5％ (17/83) vs.36.6％ (26/71),P＜0.05].Conclusions Moxifloxacin-based triple therapy combined with rebamipide has a more beneficial effect on Hp related symptoms,a higher Hp eradication rate and a lower Hp re-infection rate for type 2 diabetic patients.

Objective To compare the efficacy and safety between postoperative chemoradiotherapy and postoperative chemotherapy alone in patients with gastric cancer by a meta-analysis of randomized controlled trials (RCTs).Methods Chinese Scientific Journal Full-Text Database (January 1979-June 2013),VIP (January 1989-June 2013),Chinese Biomedical Literature Database (January 1978-June 2013),Cochrane Library (Issue 6,2013),PubMed (January 1966-June 2013),and EMBASE (January 1974-June 2013) were searched to identify RCTs of postoperative chemoradiotherapy versus chemotherapy alone in patients with gastric cancer.The obtained data were analyzed using RevMan 5.2 and Stata 12.The difference between two groups was estimated by calculating the risk ratio (RR) with 95％ confidence interval (CI).Results A total of 1 143 patients from 11 RCTs were included in the meta-analysis according to the inclusion and exclusion criteria.Our results showed that postoperative chemoradiotherapy significantly increased 1-,2-,and 3-year overall survival rates (RR =1.20,95％ CI=1.10-1.30,P=0.00; RR =1.34,95％ CI=1.16-1.56,P=0.00; RR =2.62,95％ CI=1.72-3.97,P=0.00) and 3-and 5-year disease-free survival rates (RR =1.10,95 ％ CI =1.00-1.21,P =0.04; RR =1.27,95％ CI =1.02-1.60,P =0.04).The incidence of grade 3 or 4 gastrointestinal tract reactions,liver function impairment,bone marrow suppression,and hand-foot syndrome was low and showed little difference between two groups (P =0.03-0.78).Conclusions Postoperative chemoradiotherapy can prolong the survival of patients with gastric cancer,and the patients have good tolerance to chemotherapy drugs.

Objective To investigate the effect of gastrodin on rat vascular smooth muscle cell (VSMC) migration induced by platelet-derived growth factor-BB (PDGF-BB) and its possible mechanisms.Methods Enzyme digestion method wasused to obtain rataorticVSMCs and be purified bypassage.Immunofluorescence staining was used to identify VSMC marker proteins.A PDGF-BB induced cell migration model was established.Transwell chamber assay was used to evaluate the effect of gastrodin on PDGF-BB induced VSMC migration.Western blots were performed to detect the phosphohorylation levels of c-jun N-terminal kinase (JNK).Results The purity of primary cultured VSMC was more than 99％.The VSMC migrated number in the PDGF-BB group was 85.2 ± 3.486 per field.It was significantly more than 42.5 ± 1.927 per field in the control group (t =9.981,P＜0.001),and gastrodin was enable to make PDGF-BB induced the number of VSMC migration significantly reduce to 71.3 ± 1.783 per filed (t=3.550,P =0.002).Western blots analysis showed that gastrodin inhibited PDGF-BB induced JNK phosphorylation (0.190 ± 0.015 vs.0.190 ± 0.015; t =14.548,P =0.000).Conclusions Gastrodin inhibits PDGF-BB induced VSMC migration,its mechanisms may be associated with the inhibition of the JNK signaling pathway activation.

OBJECTIVETo evaluate the feasibility and efficacy of unilateral pedicle screw fixation in treating thoracolumbar fractures through paraspinal approach.

METHODSFrom January 2006 to January 2009,21 patients with single level thoracolumbar fracture without neurological symptoms were treated with unilateral pedicle screw fixation through paraspinal approach. There were 14 males and 7 females,aged from 21 to 65 years old with a mean of 36.4 years. The duration from injury to operation ranged from 6 h to 5 d with an average of 3 d. According to the classification of Denis fracture, compression fractures happedned in 12 cases and burst fractures happened in 9 cases,including 1 case with T5 fracture, 2 cases with T7 fracture, 2 cases with T10 fracture, 3 cases with T11 fracture, 8 cases with T12 fracture, and 5 cases with L1 fracture. Based on the Flankel grade, all patients were classified as grade E. Anterior vertebral body height ratio, sagittal Cobb angle, condition of internal fixation failure, visual analogue score (VAS) were evaluated.

RESULTSAll patients were followed up from 12 to 36 months with an average of 20.5 months. No internal fixation failure was found. Anterior vertebral body height ratios at preoperative 3 days after operation and last follow-up were 54.3 +/- 2.8, 92.9 +/- 1.5, 93.8 +/- 1.7, respectively;sagittal Cobb angle at the three timepoints were (27.8 +/- 2.5) degrees, (5.3 +/- 0.8) degrees, (6.3 +/- 1.4) degrees, respectively; the difference was statistical significant (P < 0.05). VAS was (1.2 +/- 0.4) points at last follow-up and had obviously improved (P < 0.05).

CONCLUSIONTreatment of thoracolumbar fractures with unilateral pedicle screw fixation through paraspinal approach is safe with the advantages of micro-trauma and less blood loss,which can not only completely retain the posterior spinal complex structure, reinforce the spinal stability, raise the reductional quality, but also improve the strength of fixation and the distribution of stress force.
