OBJECTIVETo explore the therapeutic effects of internal fixation with Herbert screws for the treatment of Pipkin type I and type II femoral head fractures.

METHODSFrom January 2008 to December 2012, 23 patients with Pipkin type I and type II femoral head fractures were treated with open reduction and internal fixation by Herbert screws through Kocher-Langenbeck approach. Twenty-three patients (aged 18 to 52 years with a mean of 35.5 years, including 18 males and 5 females patients, 8 left hips and 15 right hips) with femoral head fractures and posterior hip dislocation. The fracture was classified according to Pipkin classification based on the radiographic findings, 5 patients had type I and 18 had type II fractures. The duration time from admission to the operation ranged from 6 to 72 h (averaged 32 h). The clinical and radiographic outcomes of the patients were measured using Thompson-Epstein scoring scale. The Harris hip score(HHS) was used to evaluate and compare hip functions at the latest follow-up between affected and healthy sides.

RESULTSAll the patients were followed up, and the duration ranged from 20 to 48 months (averaged 30 months). According to Thompson-Epstein system, 12 patients got an excellent result, 6 good, 4 fair and 1 poor. The average HHS at the finial follow-up was 87.80 ± 8.46 (ranged from 66 to 95), which is similar to that in the healthy side 90.10 ± 6.35 (ranged from 72 to 98) (t = 1.044, P = 0.302). The complications such as deep infection, and deep vein thrombosis were not found. At the 3rd year during follow-up,4 patients had avascular necrosis of femoral head. At the 1st year of follow-up, 1 patient had hip pain after walking,screws loosening and shift after trauma,and serious complications of traumatic arthritis. All the 5 patients were treated with total hip arthroplasties.

CONCLUSIONThe treatment of internal fixation with Herbert screws through the Kocher-Langenbeck approach is effective for Pipkin type I and type II femoral head fracture. The method is reliable and valuable for recommendation. However, such fracture may have avascular necrosis of femoral head and complication of traumatic arthritis, which should be observed carefully in clinic with preparation of the prevention and treatment measures.

OBJECTIVETo study the impacts of exposure to electromagnetic radiation (EMR) on liver function in rats.

METHODSTwenty adult male Sprague-Dawley rats were randomly divided into normal group and radiated group. The rats in normal group were not radiated, those in radiated group were exposed to EMR 4 h/ d for 18 consecutive days. Rats were sacrificed immediately after the end of the experiment. The serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), and those of malondialdehyde (MDA) and glutathione (GSH) in liver tissue were evaluated by colorimetric method. The liver histopathological changes were observed by hematoxylin and eosin staining and the protein expression of bax and bcl- 2 in liver tissue were detected by immunohistochemical method. Terminal-deoxynucleotidyl transferase mediated nick and labelling (TUNEL) method was used for analysis of apoptosis in liver.

RESULTSCompared with the normal rats, the serum levels of ALT and AST in the radiated group had no obvious changes (P>0.05), while the contents of MDA increased (P < 0.01) and those of GSH decreased (P < 0.01) in liver tissues. The histopathology examination showed diffuse hepatocyte swelling and vacuolation, small pieces and focal necrosis. The immunohistochemical results displayed that the expression of the bax protein was higher and that of bcl-2 protein was lower in radiated group. The hepatocyte apoptosis rates in radiated group was higher than that in normal group (all P < 0.01).

CONCLUSIONThe exposure to 900 MHz mobile phone 4 h/d for 18 days could induce the liver histological changes, which may be partly due to the apoptosis and oxidative stress induced in liver tissue by electromagnetic radiation.

OBJECTIVETo investigate the clinical outcomes of surgical treatment of fracture of the fifth metatarsal base combined with degree III lateral ligament injury of ankle.

METHODSFrom January 2008 to December 2011, 32 patients with fracture of the fifth metatarsal base combined with degree III lateral ligament injury of ankle were treated with surgery. Fractures were fixed with compressed canulated screw and ligaments were repaired with suture anchors. After operation, ankle joints were fixed in neutral position and slightly valgus position by plaster slab. Taking out stitch was performed at 2 weeks after operation and non-weight loading walking by double crutches support started; after the 6 weeks, remove the gypsum and part-weight loading walking by brace protection; at the 8 weeks after operation, completely weight loading walking was permitted. American Orthopaedic Foot and Ankle Society (AOFAS) was used to evaluate the clinical effect.

RESULTSThirty-two patients were followed up from 8 to 18 months with an average of 12 months. All fractures obtained healing with an average time of 12.5 weeks (ranged, 8 to 24 weeks). According to the standard of AOFAS, 18 cases got excellent results and 14 good.

CONCLUSIONThe method that fracture fixation with compressed canulated screw and ligament repair with suture anchors can obtain satisfactory effects in treating fracture of the fifth metatarsal base and degree III lateral ligament injury of ankle.

The present study evaluated the effect of non-thermal plasma on skin wound healing in BalB/c mice. Two 6-mm wounds along the both sides of the spine were created on the back of each mouse (n=80) by using a punch biopsy. The mice were assigned randomly into two groups, with 40 animals in each group: a non-thermal plasma group in which the mice were treated with the non-thermal plasma; a control group in which the mice were left to heal naturally. Wound healing was evaluated on postoperative days (POD) 4, 7, 10 and 14 (n=5 per group in each POD) by percentage of wound closure. The mice was euthanized on POD 1, 4, 7, 10, 14, 21, 28 and 35 (n=1 in each POD). The wounds were removed, routinely fixed, paraffin-embedded, sectioned and HE-stained. A modified scoring system was used to evaluate the wounds. The results showed that acute inflammation peaked on POD 4 in non-thermal plasma group, earlier than in control group in which acute inflammation reached a peak on POD 7, and the acute inflammation scores were much lower in non-thermal group than in control group on POD 7 (P<0.05). The amount of granular tissue was greater on POD 4 and 7 in non-thermal group than in control group (P<0.05). The re-epithelialization score and the neovasularization score were increased significantly in non-thermal group when compared with control group on POD 7 and 10 (P<0.05 for all). The count of bacterial colonies was 10(3) CFU/mL on POD 4 and <20 CFU/mL on POD 7, significantly lower than that in control group (10(9) CFU/mL on POD 4 and >10(12) CFU/mL on the POD 7) (P<0.05). It was suggested that the non-thermal plasma facilitates the wound healing by suppressing bacterial colonization.

Professor DONG Gui-rong's theoretical principle and manipulation points for peripheral facial paralysis were introduced in details from the angels of syndrome differentiation, timing, acupoint prescription and needling methods. For the syndrome differentiation and timing, the professor emphasized to check the treatment timing and follow the symptoms, which should be treated by stages, besides, it was necessary to find and distinguish the reason and nature of diseases to have a combined treatment of tendons and muscles. For the acupoint prescription and needling methods, he has proposed that the acupoints selection should be compatible of distal and lacal, and made a best of Baihui (GV 20) to regulate the whole yang qi, also he has paid much attention to the needling methods and staging treatment. Under the consideration of late stage of peripheral facial paralysis, based on syndrome differentiation Back-shu points have been selected to regulate zang-fu function, should achieve much better therapeutic effect.
