Objective The aim of this study was to evaluate the clinical factors contributing to the operative effects in patients with acetabular fracture.Methods A total of 129 cases of patients with acetabular fracture were retrospectively analyzed from Jun 2006 to Jan 2011 in The Second Hospital of Shaoxing.Of the 129 acetabular fracture patients,96 cases were in the superior group and 33 patients in the inferior group according to Merled'Aubigne-Postel methods.The potential clinical factors related to the operative effects in acetabular fracture patients were evaluated by the method of logistic regression analysis.Results The superior rate was 74％ in this study.Single factor analysis demonstrated that the diaplastic quality(x2=21.53,P ＜0.01),the femoral cartilage defect(x2 =17.50,P ＜0.01),the inra-aticular free bone(x2=12.18,P =0.0005),the type of fracture (x2 =7.24,P =0.0071) and the timing of operation (x2 =4.36,P =0.037) were correlated with operative effects in acetabular fracture patients.The binary logistic regression analysis indicated that non-anatomic diaplastic (OR =4.17,P =0.01)and the femoral cartilage defect(OR =3.11,P =0.03) were independent risk factors for operative effects in patients with acetabular fracture.Conclusions The prognosis of patients with acetabular fracture,which was complex,was affected by multiple factors.And introperatively,the anatomic reestablishment should be performed in order not to affect the post operative hip function.

Objective To investigate the ultrasound imaging findings of anatomical relationship between femoral artery and vein in children of different ages.Methods Sixty-five children aged 4 months-7 years were enrolled in this study.The children were divided into 3 age groups: group Ⅰ＜ 1 yr;group Ⅱ 1-3 yr and group Ⅲ＞ 3,≤ 7 yr.A protable ultrasound machine was used.The probe was placed at the level of inguinal ligament and 2 and 4 cm below inguinal ligament.The children were placed in supine position.The legs were placed in 2 positions:(1)extended and in standard anatomical position and(2)flexed and 45° abducted and 45° laterally rotated.Results The examination showed that at the level of inguinal ligament,the femoral vein lay behind and lateral to femoral artery in 91% of children.At the level of 4 cm below inguinal ligament,the femoral vein lay posterior and lateral to the femoral artery in all children.When the leg was placed in abducted and laterally rotated,the depth of femoral vein was reduced and the vein was less overlapped by artery in all children,especially in preschool children.Conclusion At the level of 4 cm below inguinal ligament,the femoral vein lies posterior and lateral to the femoral artery in children.When the leg is placed in abducted and laterally rotated,the depth of femoral vein is reduced and the vein is less overlapped by artery.It is indicated that femoral vein puncture should be performed at the level of 4 cm below inguinal ligament with the leg flexed and abducted in all children,especially in preschool children.

OBJECTIVE: To explore the efficacy of Y-type anatomical plate in patients with distal humeral fracture. METHODS: Thirty three patients suffered from comminuted distal humeral fracture undertook the operation. Among them, 15 were supracondyle fracture, and the other 18 were intercondyle fracture. All patients were treated with middle post elbow incision, reposition, and fixed with Y-type anatomical steel plate. RESULTS: All patients were followed up for 16 months after the operation, and all fractures healed. The average healing time was 3. 5 months. The elbow joint function according to Aitken and Rombeck's elbow function rating system was evaluated, and the results were as follows: the function recovery was excellent in 29 patients, good in 2 and fair in the other 2 patients. The excellence rate was 93. 9%. CONCLUSION Y-type anatomical steel plate is excellent in the treatment of distal humeral fracture.

Aim To investigate the protective effects of total triterpenoid from Prunella vulgaris L. ( TTP) on CCl4-induced hepatic fibrosis in rats and its mecha-nism. Methods Rat liver fibrosis was induced by 50% CCl4 twice a week for 12 weeks. From the 5th week, all the therapeutic groups were treated with the TTP(25, 50, 100 mg·kg-1 ) and the colchicine (0. 1 mg· kg-1 ) respectively once a day for 8 weeks. At the end of the twelfth week, the levels of ALT, AST, HA, PCⅢ, CⅣ, MDA, SOD, GSH-Px, Hyp were measured . HE and Masson staining were used to evalu-late the degree of hepatic fibrosis. The mRNA expres-sion ofα-SMA, procollagen I, Smad2, Smad3, Smad7 in liver was detected by RT-PCR, and the p-ERK pro-tein expression was evaluated by Western blot. Results Compared with the model group, TTP(25, 50, 100 mg·kg-1 ) not only reduced serum content of ALT, AST, HA, PCⅢ, CⅣand Hyp, MDA in liver tissue, improved the morphologic changes of hepatic fibrosis, but also increased SOD and GSH-Px activity. Moreo-ver, it decreased the α-SMA, procollagen I, Smad2, Smad3 mRNA expression and increased Smad7 mRNA expression in liver tissues obviously. Furthermore, TTP reduced the protein expression of p-ERK. Conclusions TTP can protect rats from CCl4-induced liver fibro-sis. The mechanism of this process may involve inhibi-ting the expression of p-ERK and interference with TGF-β1/Smad signal transduction pathway.

ObjectiveTo investigate the effect of whole-period psychiatric rehabilitation on outpatients with schizophrenia.Methods90 outpatients with schizophrenia were randomly divided into the study group and control group with 45 cases in each group. All cases in two groups received pharmacotherapy, but cases of study group were added with whole-period psychiatric rehabilitation. Assessments were performed before and after study. All subjects were evaluated with the Brief Psychiatric Rating Scale (BPRS) and Social Disability Screening Schedule (SDSS).ResultsThe outcome of the study group was significantly superior to the control group on overall improvement according to the reductions of BPRS score, Anergia factor score, thought disturbance factor score, suspiciousness factor score and SDSS score(P<0.05-0.01).ConclusionThe whole-period psychiatric rehabilitation may play an important role in controlling symptoms and improving social function to outpatients with schizophrenia.

OBJECTIVETo observe clinical therapeutic effect of acupuncture kinetotherapy for acute simple laryngitis of wind-heat type and to probe the mechanism.

METHODSEighty cases were randomly divided into a test group and a control group, 40 cases in each group. The test group were treated with acupuncture kinetotherapy (Acupuncture was given at Kaiyin point No. 1 combined with deep respiratory movement of the glottis), once daily. The control group were treated with ultrasonic aerosol inhalation of 0.9% sodium chloride injection, gentamicin sulfate injection 80 000 U and Dexamethasone injection 5mg, twice a day. The treatment was given for 5 days for the 2 groups.

RESULTSThe cured and markedly effective rate was 90.0% in the test group and 82.5% in the control group with no significant difference between the two groups (P>0.05); in the test group there was a very significant difference before and after treatment in the cumulative score of symptoms and the acoustic parameters (P<0.01).

CONCLUSIONAcupuncture kinetotherapy has obvious therapeutic effect on acute simple laryngitis of wind heat type, with no toxic and adverse effects.

AIM:To investigate the efficiency of 2-methoxyestradiol (2-ME) as radiosensitizing agent for the treatment of lung cancer cells. METHODS:Cell line A549 and GLC-82 originated from human non-small cell lung cancer were cultured in vitro. Study group (2-ME in different concentrations) and control group without 2-ME were set up. Cell proliferation was measured by MTT assay that lung cancer cells were treated with 2-ME for 24 h,then the cells were exposed from 0 to 8Gy radiation,and the survival fraction was determined by clone forming test. Flow cytometry was used to measure the effects of 2-ME on cell cycle distribution. RESULTS:MTT assay showed minimum effective concentration value was 0.15625×10~(-6) mol/L in GLC-82 and 1.25×10~(-6) mol/L in A549 cells. Compared to control group,exposed GLC-82 cells or A549 cells to minimum effective concentration of 2-ME for 24 h before irradiation resulted in an enhancement of radiation. The protection enhancement factor was 1.98 and 2.06 in GLC-82 and A549 cells,respectively. Flow cytometry analysis of cell cycle progression demonstrated G_2/M phase arrest in both cells in a dose dependent manner. No obvious change of CDK2 activity in both GLC-82 cells and A549 cells was observed. CONCLUSION:2-ME enhances radiosensitivity by G_2/M phase arrest in the cell cycle.

Objective To study the effects of vascular endothelial growth factor(VEGF)on production of pulmonary surfactants.Method Fetal rat lungs were obtained at 19-day gestation.Primary culture of typeⅡalveolar epithelial cells(AECⅡ)was performed using IgG panning technique.The rats was divided into groups: VEGF,Dexamethasone,VEGF plus Dexamethasone and a control.Total phospholipids,phosphatidylcholine (PC),phosphatidyl glycerol(PG)and sphingornyelin(SM)were determined.Results expressed as mean?SEM. Comparison between groups were made with LSD-t test and one -way ANOVA.Result VEGF,Dexamethasone and VEGF plus Dexamethasone groups showed increased amount of total phospholipids and its compositions on the first day of culture.Conclusions VEGF-165 promotes the production and secretion of pulmonary surfactant. VEGF and Dexamethason may go through different mechanism for enhancement of synthesis of pulmonary surfactant,thereby improve biological function of AECⅡ.
