Chinese medicine showed many treatments with clinical efficacy. Therefore, Chinese medicine has been widely used in clinics. This paper was to review the research progress of Chinese medicine treatment for chest contusion.

Objective To analyze the reliability and reproducibility of three different classification systems of Tile,Young Burgess and AO in pelvic fracture.Methods One hundred cases of pelvic fractures conforming to the inclusion standard and with intact imaging data were selected and classified according to these 3 classification methods by the orthopedic surgeons.The retyping was performed at 8 weeks after disorganizing the order.Then reliability and reproducibility analysis was performed by using the Kappa values and typing consistency.Results The reliability Kappa values during the two periods before and after the Tile classification were 0.743 and 0.745 respectively,and the reproducibility Kappa value was 0.771;the reliability Kappa values during the two periods before and after the Young-Burgess classification were 0.587 and 0.590 respectively,and the reproducibility Kappa value was 0.691;the reliability of Kappa values during the two periods before and after the OA classification were 0.402 and 0.406 respectively,and the reproducibility Kappa value was 0.498.Conclusion the Tile classification has better reliability and reproducibility than the other two classifications in pelvic fracture,which is easy to master and apply.

Intracranial infection is a common and serious complication of acute severe traumatic brain injury, with high mortality and disability rates, which significantly affects the prognosis. In recent years, with the widespread use of antibiotics, antibiotic-resistance rates of pathogens have risen year by year, and the choice of sensitive antibiotics is less and less, sometimes even in difficulties of no drugs available. This paper reviewed the treatment process of 1 case with intracranial infection caused by multi drug-resistant Klebsiella pneumonia after severe traumatic brain injury . The aim is to summarize the clinical experience.

AIM To investigate the preventive effects of Shangke Huangshui Gauze (Scutellariae Radix,Coptidis Rhizoma,Phellodendri chinensis Cortex,etc.) on vascular crisis after digital replantation.METHODS Sixty-eight cases of patients with amputated digits meeting the inclusion criteria were randomly divided into observation group (36 cases with 57 fingers) and control group (32 cases with 54 fingers),the former was wet-dressed with Shangke Huangshui Gauze,the latter was bandaged with sterile dry gauze.The observation and comparison were made between the two groups on four coagulation indexes,visual analog scores (VAS),improvement of swelling degrees,the occurrence rates and survival rates of vascular crisis after operation,together with the evaluation of efficacy and adverse reaction.RESULTS In the observation group,the 7th day after operation,the prothrombin time,activated partial thromboplastin time,international normalized ratio,thrombin time and swelling improvement rate were higher than those in the control group;but the fibrinogen and postoperative 4 days' VAS pain score were lower than those in the control group.The incidence rates of vascular crisis and adverse reaction in the observation group were lower than those in the control group,and the survival rate of replanted fingers was higher than that in the control group.CONCLUSION Shangke Huangshui Gauze can prevent the occurrence of vascular crisis after digital replantation to a certain extent without obvious adverse reaction.

AIM To investigate the effects of Sanqi Huayu Oral Liquid (Notoginseng Radix et Rhizoma,Corydalis Rhizoma) on femoral shaft comminuted fracture caused by trauma in perioperative period of high-risk groups.METHODS One hundred and twenty patients meeting the inclusion criteria were randomly and equally divided into treatment group and control group.The control group was treated by low molecular weight heparin calcium injection,while the treatment group was additionally given Sanqi Huayu Oral Liquid.Two groups' levels of serum IL-6,TNF-α and D-D were detected on pre-operation and the 1 st,3rd,7th after operation,respectively.Additionally,the adverse drug reactions were also observed.RESULTS There were no statistically significant differences in the levels of serum IL-6,TNF-α and D-D between the two groups before operation.The first day after operation,the levels of serum IL-6,TNF-α and D-D between the two groups showed increasing trends,which had similar elevated levels without statistically significant differences.The third day after operation,the levels of serum IL-6,TNF-α and D-D between the two groups presented downward trends,but those in the treatment group were decreased more markedly with statistically significant differences.Furthermore,the seventh day after operation,the levels of serum IL-6,TNF-α and D-D between the two groups were lower than those before the operation,and these indices in the treatment group were lower than those in the control group with statistically significant differences.CONCLUSION Sanqi Huayu Oral Liquid can not only effectively reduce the levels of serum IL-6,TNF-α and D-D in perioperative period of high-risk groups,but also prevent the formation of deep vein thrombosis.

Objective To investigate the protective effect of umbilical cord mesenchymal stem cells (UCMSCs) on traumatic brain injury (TBI) in rats.Methods Thirty healthy Sprague-Dawley rats (10 rats for each group) were randomly divided into normal control group (normal),model group (injection of saline after TBI) and UCMSCs transplantation group (injection of UCMSCs after TBI).The rats in experimental groups were sacrificed on the 10th day after UCMSCs transplantation.The percentage of UCMSCs in brain tissue was detected by flow cytometry.The pathological changes of brain tissue were observed by hematoxylin-eosin (HE) staining method.The expressions of vascular endothelial growth factor (VEGF),glial fibrillary acidic protein (GFAP) and brain-derived neurotrophic factor (BDNF) in brain tissue were measured by immunohistochemistry and immunofluorescence double staining.The neurological deficit was evaluated by neurological deficit degree.Results The percentage of CD90,CD73 and CD105 cells in the UCMSCs transplantation group was significandtly higher than that in the model group (0.4％ vs 0.1％,P＜0.05).The results of HE staining showed that the brain injury of the transplanted group was alleviated compared with the model group (P＜0.05).The VEGF of the brain tissue in injury area in the UCMSCs transplantation group was higher than that in the model group (P＜0.05).The number of GFAP and BDNF positive cells in the UCMSCs transplantation group was higher than that in the model group (P＜0.05),and the neurological deficit score was also higher than that in the model group (P＜0.05).Conclusions UCMSCs transplantation for the treatment of TBI rats can effectively reduce the vascular damage in the injury area and promote nerve recovery.

Objective: To compare the clinical efficacy between arthroscopic riveting with line and lateral retinacular release plus medial patellofemoral ligament reconstruction in the treatment of habitual patellar dislocation. Methods: A retrospective study was conducted of the 40 children with habitual patellar dislocation who had been treated at Department of Pediatric Orthopaedics, Foshan Hospital of Traditional Chinese Medicine from January 2016 to December 2016. They were divided evenly into an observation group and a control group according to the treatment methods (n=20). In the observation group which was treated by lateral retinacular release plus medial patellofemoral ligament reconstruction, there were 14 boys and 6 girls, with an age of 14.2±1.2 years and an average number of dislocations of 5.3±1.1 times. In the control group which was treated by arthroscopic riveting with line, there were 13 boys and 7 girls, with an age of 13.8±1.3 years and an average number of dislocations of 5.5±1.2 times. The 2 groups were compared in terms of visual analogue score (VAS), Q-angle, knee motion, Lysholm score and Kujala score of the knee at the last follow-ups. Results: The 2 groups were comparable due to insignificant differences in preoperative general data between them (P>0.05). The observation and control groups were followed up for 13.3±1.2 months and 12.9±1.2 months, respectively, showing no significant difference between them(P>0.05). At the last follow-ups, the observation group had a significantly lower VAS score (2.2±0.8 pints), a significantly smaller Q-angle (14.5°±1.2°), significantly larger knee motion (30.3°±3.8°), and significantly higher Lysholm (91.6±5.3 points) and Kujala scores (93.2±2.8 points) than the control group (4.3±1.1 points, 17.8°±1.6°, 23.4°±3.4°, 81.4±4.4 points and 82.0±5.4 points, respectively) (all P<0.05). Conclusion In the treatment of habitual patellar dislocation, lateral retinacular release plus medial patellofemoral ligament reconstruction can lead to improvements in knee function and clinical symptoms and better clinical outcomes than arthroscopic riveting with line.

Objective To investigate the effects of human umbilical cord mesenchymal stem cells (UC-MSCs ) on vascular endothelial growth factor ( VEGF ) and monocyte chemoattractant protein-1 ( MCP-1 ) of acute myocardial ischemia-reperfusion (AMI-R) injury in rats. Methods 24 Sprague-Dawley rats were randomly divided into sham group, AMI-R group and UCMSCs treatment groups on average. The rats were sacrificed on the 10th day after UCMSCs transplantation, and the myocardial tissues below the ligature were taken. The mRNA and protein expressions of MCP-1 of the tissue were detected by RT-PCR and Western Blot respectively, and the expression of VEGF protein was detected by immunohistochemistry. Results The relative expression levels of MCP-1 mRNA and the protein in UCMSCs group were significantly lower than those in sham group and AMI-R group (all P<0.05). The expression of VEGF protein in UCMSCs group was significantly higher than that in sham group and AMI-R group, the differences were statistically significant(all P<0.05). Conclusion UCMSCs transplantation can promote the angiogenesis and decrease the inflammation reaction in the treatment of acute myocardial ischemia-reperfusion injury.
