Objective To observe the clinical effects of anterior plates with titanium mesh and bone graft (auto and allo) in treatment of cervical spine fractures. Methods 42 cases of fractures of cervical spine treated with anterior plates with titanium mesh. Results The bone graft (auto and allo) were followed up for 4 to 28 months (mean 17 months). The preoperative and postoperative nerve functions were evaluated according to JOA criteria. The cervical curvatures, sink or shift of the mesh and bone fusion were evaluated by X rays. There were no significant complications during perioperative periods. The functions of spinal cord were improved, the cervical curvatures were restored, and no sinking or shifting of the mesh was observed. There was also no loosening of plate or screw. The fusion began 3.5 months postoperatively, and a good fusion could be observed 1 year postoperatively. Conclusion By application of anterior plates with titanium mesh and bone graft (auto and allo) in treatment of cervical spine fractures, the cervical curvature and stability can be restored, the iliac lesion and long operation duration caused by the harvest from ilium can be avoided, better fusion and quicker recovery can be obtained.

There was a statistically significant post-treatment difference in the VAS score between the treatment and control groups (P<0.05). The total efficacy rate was 95.8% in the treatment group and 83.3% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Xi-Cleft point acupuncture plus surrounding electroacupuncture is an effective way to treat occipital neuralgia.

Objective To explore a biodegradable drug?loaded composite scaffold and determine its bone regeneration and local long?term drug release ability. Methods In this study, RFP?loaded a novel poly (caprolactone)?b?poly (lactide?co?gly?colide)/β?TCP composite scaffold was produced using particle?leaching/freeze?drying technique. And the obtained composite scaffold was characterized by SEM, TGA, UV spectrophotometer, universal testing machine and so on. New Zealand rabbits were used to prepare bone defects, which was treated by the implantation of active artificial bone loaded with or without RFP. The blank group was untreated. Then the repairing effects of the materials were examined. Results The obtained porous scaf?fold has inter?connected and uniformly distributed pores, and the diameters of pores range from 200 μm to 300 μm. Many mi?cropores (10 μm to 50 μm) can be observed on the wall of macropores. The total porosity of the porous composite scaffold can reach as high as 83.4%; the β?TCP content of the scaffolds is 51.2%. Meanwhile, the addition of β?TCP avoided volume shrinkage compared with b?PLGC scaffold; Additionally, the porous composite scaffold has good compressive strength ( 240 kPa) and compressive modulus (1.0 MPa); And the drug loading of the scaffold was 3.2%,which could smoothly release drug for 63 days after a period of burst release for a week. All defects in the experimental groups were radiographically repaired. There were significant differences between the experimental groups and the control group. Conclusion RFP?loaded poly (cap?rolactone)?b?poly (lactide?co?glycolide)/β?TCP composite scaffold is expected to benefit in drug therapy and bone repair in the treatment of bone tuberculosis.

Objective To observe the clinical efficacy of electroacupuncture in treating herpes zoster.Method Ninety patients with herpes zoster were randomized into treatment group 1, treatment group 2, and a control group, 30 cases in each group. Treatment group 1 was intervened by surround needling at Ashi points (deep needling, by 33 mm) plus electroacupuncture; treatment group 2 was by surround needling at Ashi points (superficial needling by 16 mm) plus electroacupuncture; the control group was by oral administration of Valacyclovir Hydrochloride tablets plus Vitamin B1. After 10-day treatment, the blister-breaking time, crust-forming time, and the time of falling-off of the crust, and Visual Analogue Scale (VAS) were observed, and the clinical efficacies were compared.Result The recovery rate and total effective rate were respectively 73.3% and 93.3% in treatment group 1, versus 46.7% and 86.7% in treatment group 2, and 33.3% and 63.3% in the control group. The recovery rate of treatment group 1 was significantly different from that of treatment group 2 and the control group (P<0.01,P<0.05). The total effective rates of treatment group 1 and 2 were both significantly different from that of the control group (P<0.01,P<0.05). The blister-breaking time, crust-forming time, and crust falling-off time of treatment group 1 were significantly different from that of treatment group 2 and the control group (P<0.01,P<0.05). The crust-forming time and falling-off time of treatment group 2 were significantly different from that of the control group (P<0.05). The VAS scores were markedly changed after the intervention in the three groups (P<0.01). After the treatment, the VAS scores of treatment group 1 and 2 were significantly different from that of the control group (P<0.01). The VAS score of treatment group 1 was markedly different from that of treatment group 2 after the treatment (P<0.05).Conclusion Electroacupuncture is an effective method in treating herpes zoster, while deep surround needling at Ashi points plus electroacupuncture can effectively inhibit the development of blisters, promote crust-forming, release the neural pain, and reduce the incidence of postherpetic neuralgia.

From January 2005 to January 2008, 23 cases of fractures and dislocations of cervical spine treated with anterior decompression, reconstruction of bone graft with titanium mesh, and titanium locking plates fixation in Department of Orthopaedics, the 309 Hospital of Chinese PLA were retrospectively analyzed, including 16 males and 7 females, aged 41.9 years (ranging 25 ?65 years). The clinical effect and application value of this treatment was evaluated; the conditions at preoperative, immediate postoperative and follow-up were evaluated by JOA grade, and these radiographs were taken. Lordosis (kyphosis) of the fusion segment with Cobb's angle, and lordosis (kyphosis) of cervical spine with D value were measured to evaluate effect of reconstruction and cervical spine physiological curve. All cases were followed-up for 20.5 months (ranging 1-3 years). Clinical stability was reached in all cases during the follow-up. There were significant differences between preoperative and immediate postoperative, between preoperative and follow-up groups in terms of JOA grade, Cobb's angle and D value (P < 0.05). The JOA grade of immediate postoperative was improved compared with that during follow-up (P < 0.05). The mean improvement rate was 63% at 1 year of follow up. A good curative effect was obtained by using anterior locking plate with titanium mesh systems in treatment of cervical fractures and dislocations and a good effect of restoring and maintaining the lordosis of cervical spine can be also obtained.
