ABSTRACT

Thoracic outlet syndrome(TOS) are constellation of symptoms caused by compression of the neurovascular bundle including the brachial plexus, the subclavian artery and the subclavian vein at the thoracic outlet region. It includes neurogenic TOS, venus TOS, arterial TOS, and neurogenic TOS is the most common type. TOS has varied manifestations and lack of confirmatory testing, therefore, the diagnosis should be conbination with thorough history, physical examination and associated supplementary examinations. Conservative and surgical treatment can be choosed for TOS and the outcomes are generally good. Conservative management is the initial treatment strategy for neurogenic TOS. In cases of symptomatic vascular TOS and neurovascular TOS, which has been failed by conservative treatment, surgery should be considered more promptly.

ABSTRACT

Objective To observe the effect of Juncus effuses on osteoclasts differentiation from bone marrow macrophages (BMMs) induced by receptor activator for nuclear factor-κ B ligand (RANKL), and its mechanism thereof. Methods BMMs were isolated from whole bone marrow of 8-week-old C57/BL6 mice, and CCK-8 was used to detect the effect of Juncus on BMMs cell proliferation. Tartrate resistant acid phosphatase (TRAP) staining was used to show that 50 μg/L RANKL and 30 μg/L macrophage colony stimulating factor (M-CSF) stimulated the BMMs differentiation into osteoclasts, but the process was inhibited by Juncus (0, 6.25, 12.5 and 25 μmol/L). RT-PCR was used to detect the expressions of osteoclast-specific genes including calcitonin receptor (CTR), vacuolated H+triphosphate transporter -d2 (V-ATPase-d2) and -a3 (V-ATPase-a3), activated T nuclear factor 1 (NFATC1) and C-FOS. Results There was no inhibition in the proliferation of BMMs cells treated with Juncus less than 12.5 μmol/L detected by CCK-8. The 50 μg/L RANKL can induce BMMs differentiated into positive multinuclear giant cells detected by TRAP staining, but Juncus significantly inhibited osteoclast formation with a concentration dependence. The results of RT-PCR experiment showed that Juncus inhibited the expression of specific genes in osteoclast differentiation in concentration-dependent manner. Conclusion Juncus can inhibit osteoclast formation in concentration-dependent manner, resulting from the inhibitory effect on osteoclast specific gene expression.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the traumatic mechanism and the effectiveness of conservative and operative therapy for intra-articular fracture of calcaneus.</p><p><b>METHODS</b>Forty-eight patients (52 feet) with intra-articular fractures were divided into two groups named as conservative group and operative group. There were 30 patients in the conservative group, including 26 males and 4 females, ranging in age from 2 to 73 years, with an average of (49.2 +/- 8.5) years. The patients in conservative group were treated with manual reduction, external fixation and functional exercise at early time. Among 18 patients in the operative group, 14 patients were male and 4 patients were female, ranging in age from 26 to 66 years,with an average of (50.1 +/- 19.3) years. The patients in the operative group were treated with open reduction and internal fixation. The height and width of calcaneus, Böhler and Gissane angles were measured before and after treatment. The assessment in the function of ankle joints was scored according to AOFAS scoring system.</p><p><b>RESULTS</b>All the patients were followed up, and the duration ranged from 8 to 18 months,with a mean of 12 months. The time of weight-bearing ranged from 3 to 6 months, averaged 4 months. The fractures were fused completely on average of 12 months. The height and width of calcaneus, Böhler and Gissane angles had no statistically significance between two groups. According to AOFAS criteria,in the conservative group, 18 patients reached an excellent result, 6 good, 5 poor and 1 bad; in operative group, 4 patients reached an excellent result, 7 good, 6 poor and 1 bad. The therapeutic effect of conservative group was better than that of operative group.</p><p><b>CONCLUSION</b>Operative therapy in intra-articular fracture of calcaneus with steel plate can directly perceive the restoration (or roughly restoration sometimes) of the anatomical shapes of calcaneus, while conservative therapy has advantages such as restoration of the anatomical shapes of calcaneus, early functional practice, early healing, and avoiding operational complications as well.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To compare the differences between external fixator and volar T-shaped plate in the treatment of complicated fractures of the distal radius and ulna, and evaluate the appropriate operation method for the fractures.</p><p><b>METHODS</b>From July 2005 to July 2007, forty-eight cases of complicated fractures of the distal radius and ulna were treated with operation. There were 21 males and 9 females in the internal fixator group, ranged from 22 to 52 years old (with an average of 38.4 +/- 1.5 years). There were 10 mals and 8 femals in the external fixator group,ranged from 25 to 56 years old (with an average of 40.5 +/- 2.3 years). The X-ray films were measured to acquire radial length, palmar tilt and radial inclination after operations. The functional evaluation were scored with a modified Gartland and Werley's (GW) scoring system at 6 and 12 months after operation.</p><p><b>RESULTS</b>The patients were followed up for 12 to 18 months with an average of 14.2 months. The radial length was (8.82 +/- 0.55) mm, palmar tilt (9.23 +/- 0.86) degrees, radial inclination (19.66 +/- 1.38) degrees in the internal fixator group, while those were (8.25 +/- 0.36) mm, (8.56 +/- 0.72) degrees, (18.82 +/- 1.42) degrees in the external fixator group. The film parameter of internal fixator group was better than the external fixator group, but with no statistical significance (P > 0.05). In the internal fixator group, 16 cases obtained excellent, 7 good, 5 fair, 2 poor, while in the external fixator group, 4 cases obtained excellent, 2 good, 8 fair, 4 poor in 6 months. The GW scores of internal fixator group were lower than that of the external fixator group (P < 0.05). At 12 months after surgery, in the internal fixator group, 17 cases obtained excellent, 7 good, 5 fair, 1 poor; while in the external fixator group, 5 cases obtained excellent, 9 good, 2 fair, 2 poor. The GW score was similar between the two groups (P > 0.05).</p><p><b>CONCLUSION</b>The volar T-shaped plate fixation may offer effective stability,the short-term outcome is better than the external fixator group,and there are relatively fewer complications. But the treatment outcome of the two operation methods are similar for the long time follow up.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the different therapeutic effects of comminuted clavicular fracture with acromioclavicular external fixtatior and DCP internal fixation.</p><p><b>METHODS</b>There were 768 cases of comminuted clavicular fracture involved in the study. Among them, 528 patients (321 male and 207 female, aged from 15 to 82 years) treated with acromioclavicular external fixator, in which there were 165 cases of three parts fracture and 363 cases of more than three parts fracture; 240 patients (152 males and 88 females, aged from 17 to 64 years) treated with the internal fixation, in which there were 178 cases of three parts fracture and 62 cases of more than three parts fracture. The time between injury and treatment was 1.3 days (range, 2 h to 8 days). The results were evaluated according to Neer scoring system.</p><p><b>RESULTS</b>All the cases were followed up from 8 to 24 months. For treatment of fracture more than three parts, there was significant difference between acromioclavicular external fixation group and internal fixation group in nonunion rate (chi2=44.17, P<0.05) and in Neer scores (t=5.284, P<0.05).</p><p><b>CONCLUSION</b>Treatment with DCP internal fixation which matching the AO principles can obtain anatomic reduction, firm fixation and early functional exercise; however, treatment with self-designed acromioclavicular external fixator is an ideal therapeutic method as it has, early union of the fracture and good functional outcome with seldom complications.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate systematically Schwann cell apoptosis in Wallerian-degenerated sciatic nerve of the rat, and evaluate its time-related feature.</p><p><b>METHODS</b>Ninety-five SD rats were divided randomly into one normal group (8 rats) and 11 experimental groups (66 rats, 6 in each). Both hind legs of each rat in experimental groups were randomly divided into test leg (sciatic nerve transected) and control one (nerve uninjured). All test legs constituted a test group and all control legs constituted a control one. After operation, all rats were respectively sacrificed at 1 h, 6 h, 12 h, 24 h, 2 d, 3 d, 4 d, 8 d, 14 d, 21 d, and 30 d. We analyzed the specimens of mid-distal sciatic nerve, especially the morphological changes of the nerve, the different expression levels of S-100 protein and apoptosis-related proteins such as Bcl-2, Bax, and Fas in Schwann cells. The TUNEL method was used to detect the apoptotic rate of Schwann cells.</p><p><b>RESULTS</b>(1) The test group showed Wallerian degeneration. The number of Schwann cells began to decrease at 24 h, obviously decreased on day 3 and 4, then began to increase from day 8 and formed Bungner belt after 14 days. (2) Schwann cells generally expressed S-100 at a low level in all groups. The control group was not significantly different from the normal group. The test group had statistical significance at 1 h and day 21. (3) As an inhibitory gene protein of Schwann cell apoptosis, Bcl-2 positive rates in the control and test groups apparently elevated and were statistically different from the normal group. (4) As a promotive gene protein of Schwann cell apoptosis, the control and test groups expressed Bax at a high level and were statistically different from the normal group. (5) As a promotive gene protein of Schwann cell apoptosis, Fas positive rate in control group was slightly elevated, but had no statistical significance compared with the normal group. Fas positive rate in test group continuously elevated in a fluctuant way, with highly statistical significance compared with the normal group. (6) TUNEL detection further proved that Schwann cell apoptosis rarely existed in the normal group, and the left sciatic nerve had no statistical significance compared with the right sciatic nerve. While the test group showed lots of apoptotic nuclei at 6 h, 2 d, 4 d, and 21 d. It had highly statistical significance compared with the normal group.</p><p><b>CONCLUSIONS</b>Schwann cell apoptosis does exist in Wallerian-degenerated sciatic nerve of the rat after transection. Schwann cell apoptosis and its apoptotic genes expression have a time-related feature.</p>
