China Journal of Orthopaedics and Traumatology 2015;28(5):399-403
OBJECTIVETo discuss the clinical effects of damage control resuscitation (DCR) in treating severe multiple trauma in the pelvic fractures.
METHODSFrom March 2009 to September 2013, a restrospective analysis was conducted on the clinical data of 28 patients with multiple trauma in the pelvic fractures, including 19 males and 9 females, ranging in age from 21 to 51 years old with an average of 32.5 years old. According to Tile classification of pelvic fractures, 16 cases were type B and 12 cases were type C. Injury severity score (ISS) averaged 32.0±3.4. All cases were treated with damage contral orthopaedics and DCR strategy, namely that used immediately with small capacity of balanced salt solution on admission so as to maintain the blood pressure between 80 to 90 mmHg. At the same time, emergency phase I simple debridement plus external fixator or bundled with fixed pelvic was done, and the chest or abdomen combined injury was treated at first. And limbs fracture was temporary dealing with bone traction or plaster external fixation, etc. After bleeding was controlled by operation, fluid resuscitation was done as fast as possible and the plasma was transfused early according to the proportion of plasma and red cell suspension (2 U:1 U-3 U:2 U). Dosage of balanced salt solution and blood before remedy shock was recorded, and the removal of time of lactic acid and coagulation were observed.
RESULTSFive cases were died after 4 to 15 hours into hospital (3 cases died for severe trauma-hemorrhagic shock and 2 cases for acute respiratory distress syndrome). Twenty-three cases were remedy shock at 1.6 to 4.3 hours after injury with an average of 2.4 hours. Period I operation duration was (78.2±10.3) minutes. Dosage of balanced salt solution was (3,798±340) ml and red cell suspension was 14 to 18 U, fresh frozen plasma (FFP) was (1,267±58) ml (1U FFP=100 ml), blood platelet was 8 to 12 U for 9 patients. The removal time of lactic acid and PT-APTT was (11.4±2.1) hours and (4.3±0.8) hours. Measures were taken to correct electrolyte and acid-base imbalance was normal. The success rat of recovery was 82.2% (23/28).
CONCLUSIONDamage control resuscitation (DCR) integrates the main links such as damage control operation and allowable low blood pressure (or limited liquid resuscitation) and hemostatic control resuscitation, was early effective treatment measures for the patients with severe multiple trauma in the pelvic fractures.

China Journal of Orthopaedics and Traumatology 2014;27(6):518-521
OBJECTIVETo investigate clinical effects of damage contral resuscitation (DCR) in rescue multiple fracture with hemorrhagic shock.
METHODSFrom January 2009 to May 2013, clinical data of 24 patients suffered from multiple fracture with hemorrhagic shock were retrospectively reviewed. Among them, 18 cases were male and 6 cases were female, aged from 21 to 48 years old with an average of (32.5 +/- 4.5). Small capacity of balanced salt solution were used to maintain systolic, pressure (80-90) mmHg before operation. After control of bleeding with operation, sufficient amount of liquid were rapidly use, and plasma were supplied according to proportion of plasma and red cell suspension (1 U:2 U-1 U:1 U). After remedy of shock, fluid infusion were sustained negative balance slightly and keep acid-base equilibrium of electrolyte. Dosage of balanced salt solution and blood transfusion before remedy shock were recorded, removal time of lactic acid, coagulation function, incidence and case fatality of DIC were observed.
RESULTSFour patients were died after 6-18 h into hospital (2 cases died for acute respiratory distress syndrome and 2 cases for irreversible shock). Twenty patients with shock were corrected at 2-6 h after injury. Dosage of balanced salt solution was(4,259 +/- 268) ml,red cell suspension was (14 +/- 2) U, fresh frozen plasma was (800-1,600) ml (FFP: 1 U = 100 ml) averaged (900 + 300) ml, blood platelet was 4-6 U. Coagulation function and electrolyte were normal. Lactic acid was less than 2 mmol/L within 24 h,the success rate of recovery was 83.3% (20/24).
CONCLUSIONPerforming DCR can obvious improve success rate of remedy serious fracture combined with uncontrolled hemorrhagic shock. Supplementing FFP when correcting coagulation function should be carry out promptly in fluid resuscitation.

The epitope-G1 gene of Bovine ephemeral fever virus (BEFV) glycoprotein was synthesised by PCR and cloned into expression vector pPIC9K to construct recombinant plasmid pPIC9K-G1. Then the pPIC9K-G1 was linearized and transformed into Pichia pastoris GS 115. The recombinant P. pastoris strains were selected by a G418 transformation screen and confirmed by PCR. After being induced with methanol, an expressed protein with 26 kDa molecular weight was obtained, which was much bigger than the predicted size (15.54 kDa). Deglycosylation analysis indicated the recombinant G1 was glycosylated. Western blot and ELISA tests, as well as rabbit immunization and specificity experiments indicated that the target protein had both higher reaction activity and higher immunocompetence and specificity. The recombinant G1 protein could be used as a coating antigen to develop an ELISA kit for bovine ephemeral fever diagnosis.

OBJECTIVETo explore the clinical effects of delayed open reduction and locking compressing plate (LCP) plus bone-grafting in medullary cavity for the distal comminuted fractures of tibia.
METHODSTwenty-nine patients with the distal comminuted fractures of tibia were treated between March 2006 and September 2008, including 19 males and 10 females, ranging in age from 27 to 58 years with an average of 42.5 years. From wounded to hospital, the time was from 2 to 4 hours. According to AO classification, type 43-A1 were in 3 cases, type A5 in 12 cases, type A3 in 9 cases and type 43-C1 in 5 cases. Among them, there were 11 cases with open fracture (type Gustilo I in 5 cases, type Gustilo II in 6 cases) and 18 cases with closed fracture. Calcaneal traction was done in earlier stage (plaster external fixation in 5 cases), keeping the nagative liquid balance and electrolyte balance and improving the microcirculation. After the swolen limbs relieved markedly in 8 to 12 days,operating was done by open reduction and LCP internal fixation plus bone-grafting with own ilium in medullary cavity. Functional exercise was undergone in earlier stage and the wounded limbs loading weight on 10 to12 weeks after operation when the X-ray revealed the callus formed markedly.
RESULTSThe incision healed well without severe complication. All patients were followed up for from 6 to 14 months with an average of 12 months. All cases obtained bone union. According to the Mazur's evaluation standard, the results were excellent in 25 cases, good in 3 cases, and fair in 1 case.
CONCLUSIONThe above treatment can reduce the damage of periosteum and medullary cavity, shorten the time of bone healing and decrease the rate of bone nounion markedly. The internal fixation was reliable and less complacation after surgery, but it is very important for the right preoperation assessment to soft tissue injuries and the good operation timing choice.

Aim To investigate the inhibitory effects of gossypol on migration in gastric carcinoma cell lines and its mechanisms. Methods Gastric carcinoma cells were treated with gossypol at different concentra-tions. The effects of gossypol on cells proliferation were measured using the MTT assay. The migration of gas-tric carcinoma cells was detected by transwell assay. The activation of Akt/β-catenin pathway and the ex-pressions of pathway related proteins ( p-Akt,β-cate-nin, cyclin D1, MMP-2, E-cadherin and vimentin ) were detected by Western blot. Results Gossypol treatment could significantly inhibit the proliferation of gastric carcinoma cells in a dose-dependent manner. Transwell assay showed that the migration ability of
gastric carcinoma cells was significantly decreased. The inhibitory effect of gossypol on cells migration was more significant than the effect of gossypol on cells prolifera-tion. Compared with the control group, treatment with gossypol significantly suppressed the expressions of p-Akt,β-catenin, cyclin D1, MMP-2 and vimentin pro-tein, whereas the expression of E-cadherin was signifi-cantly up-regulated in gastric carcinoma cells in a dose-dependent manner. Conclusion These results demonstrate that gossypol represses cell migration of gastric carcinoma cells through the down-regulation of the activity of Akt/β-catenin pathway.
