BACKGROUND:Healing time and plaster used in fixed position and fixed time are different between distal radius fractures and scaphoid fracture. When both fractures occur simultaneously, you cannot choose a fixed position and determine a fixed time. One-stage internal fixation for the distal radial fractures and scaphoid fractures simultaneously can obtain a good function. OBJECTIVE:To retrospectively analyze the effects of titanium locking compression plate and Herbert screw fixation for fresh unstable distal radial fractures with scaphoid fracture. METHODS:A total of 12 patients with fresh unstable distal radial fractures combined with scaphoid fracture were treated in the Shanxi Dayi Hospital from November 2011 to June 2014. Al cases received open reduction and locking compression plate fixation of the distal radius, open reduction of scaphoid fracture or percutaneous Herbert screw fixation. Fracture healing was observed during folow-up. At 6 months after treatment, wrist joint function was evaluated with modified McBride score. Range of motion of palmar flexion, dorsiflexion, ulnar deviation, radial deviation, pronation and supination and grip strength were measured. The distal radial shortening (difference in height of styloid process of radius and ulna), and angles of ulnar deviation and palmar tilt were measured with X-ray films. The data of healthy side and affected side were compared. RESULTS AND CONCLUSION:(1) 12 cases were folowed up for 6-24 months. (2) The distal radius and scaphoid fractures healed. The healing time of distal radius was 6-12 weeks, with an average of seven weeks. Healing time of scaphoid fracture was 3-6 months, with an average of 4.2 months. (3) Wrist score was evaluated using modified McBride scoring criteria at 6 months after treatment. There were excelent in 5 cases, good in 6 cases, and average in 1 case, with the excelent and good rate of 92%. (4) No significant difference in range of motion of palmar flexion, dorsiflexion, ulnar deviation, radial deviation, pronation and supination and grip strength, angles of ulnar deviation and palmar tilt, difference in height of styloid process of radius and ulna and modified McBride score was detected between healthy side and affected side (P > 0.05). (5) The median nerve injury in two patients was recovered within 6 months after postoperative exploration decompression. No complications appeared, such as infection, dorsal muscle tendon irritation symptoms, carpal tunnel syndrome, and internal fixation failure. (6) These findings confirm that fresh unstable distal radial fractures with scaphoid fractures can be treated with open reduction of the distal radius and locking plate fixation, open reduction of scaphoid bone or percutaneous Herbert screw fixation, with reliable fixation, high fracture healing rate, and good wrist function recovery rate; the repair effect is satisfactory.

BACKGROUND:With the diversification of the choice of internal fixation for femoral intertrochanteric fracture, the fixation method for the same kind of fracture can be selected according to surgeon’s habit, and there is no unified standard. OBJECTIVE:To compare Gamma nail and proximal femoral locking plate fixation for repair of femoral intertrochanteric fractures. METHODS: A total of 94 elderly patients with unstable intertrochanteric fractures were treated in the Shanxi Armed Police Corps Hospital from April 2009 to September 2012. They were divided into two groups according to fixation methods. Gamma nail group contained 46 cases. Proximal femoral locking plate group contained 48 cases. The two fixation methods were compared and analyzed from the folowing aspects: incision length, intraoperative bleeding volume, operation time, postoperative hip function recovery, loading time and complications. RESULTS AND CONCLUSION:Incision length, intraoperative bleeding volume, loading time and complications were better in the Gamma nail group than in the proximal femoral locking plate group (P < 0.05). No significant difference in operation time was detected between the two groups (P > 0.05). The excelent and good rate of hip function was 96% (44/46) in the Gamma nail group and 92% (44/48) in the proximal femoral locking plate group at 1 year after treatment, and no significant difference was detectable between the two groups (P > 0.05). These findings suggest that Gamma nail and proximal femoral anatomic locking plate for the treatment of unstable intertrochanteric fractures can reach good recovery of hip function, but Gamma nail showed obvious advantages in incision length, intraoperative bleeding volume, loading time and complications.

BACKGROUND:Some scholars suggest that the nerve root palsy after cervical spinal stenosis treated with
decompression and implant internal fixation is related with the cervical stability and cervical lordosis, but there is controversial.
OBJECTIVE:To explore the C 5 nerve root palsy and stability after cervical spinal stenosis treated with posterior laminectomy lateral mass fixation and single-door decompression laminoplasty.
METHODS:Twenty-nine cervical spinal stenosis patients were selected and treated with posterior
decompression and implant internal fixation. Posterior laminectomy lateral mass fixation for the treatment of
cervical spinal stenosis:C3-6 lateral mass and C7 pedicel screw internal fixation was performed and caused rough surface on the facet joint;the unstable segment was confirmed according to the preoperative anteraposterior
plain film and dynamic radiographs combined with MRI and CT images, and then the corresponding segments were treated with lateral mass internal fixation, single-door decompression laminoplasty and laminoplasty.
RESULTS AND CONCLUSION:Al the 29 cervical spinal stenosis patients were fol owed-up for 8 months to 2.3 years. Among them, 14 cases were treated with posterior laminectomy lateral mass fixation, two cases had nerve root palsy in the early stage after implantation, three cases had incomplete paralysis after long-term symptom recurrence and treated with second surgery of scar remove and decompression;15 cases were treated with single-door decompression
laminoplasty, and one case had C 5 never root palsy and shoulder abduction dysfunctionafter treatment, no preoperative symptom recurrence. The nerve root palsy wil restored in 6 weeks for shortest and 9 months for longest. As the limitation of the case number, it is not clear whether there were significant differences in the correlation between C 5 nerve root
palsy and segmental stability, cervical lordosis, spinal decompression degree and the range for spinal cord shift, as wel as the nerve root palsy degree and the cervical spinal stenosis recurrence caused by forward scar between two
treatment methods, so accumulation observation of the cases and clinical experience are needed.

Objective To discuss the feasibility of Shuyisha as hemostasis and repair material for liver wound. Methods Hemolysis rate, acute toxicity and eytotoxicity of Shuyisha were measured. A hemorrhage model was established by making an open wound (5 mm× 3 nun ×2 mm) on the left liver lobe of mice. Hemostasis was performed with Shuyisha in experimental group and with Surgicel in control group, when the hemostatic time and total blood loss (TBL) were accurately recorded and regular macro-scopic and histological observation carried out. Results The hemolysis rate of Shuyisha was 2.33%, with maximum tolerance does of over 0.48 g/kg and the eytotoxicity at zero. The hemostatie time of Shuy-isha was (5.00 ±0.00) s, with total blood loss of (0.88±0.18) g/kg, better than Surgicel (P< 0.05). Shuyisha was degraded completely within 14 days, with the wound healed within 21 days in ex-perimental group, much better than Surgieel. Conclusions The hemolysis rate, acute toxicity and cy-totoxicity of Shuyisha are up to the requirement of biomedical materials. Shuyisha has effective hemosta-sis, which may be related to its molecular structure and adhesion.

Objective To evaluate the clinical efficacy and safety of tapering the dosage of recom-binant human tumor necrosis factor receptor-Fc fusion protein (rhTNFR-Fc) combined with DMARDs in the treatment of peripheral joints involvement of ankylosing spondylitis. Methods Sixty patients who met the classification criteria of ankyloding spondylitis were enrolled. Meanwhile, all patients had one or more of the following joint involvement: hip, knee, ankle, and shoulder. Their BASDAI was higher than 4, joint pain VAS≥4, ESR ≥30 mm/1 h and CRP≥8 mg/L. Tuberculosis, hepatitis B, hepatitis C infection or other microorgan-isms infections were excluded. All enrolled patients had no serious heart,liver,kidney, or other internal organ involvement. During the first stage (The first eight weeks patients were matched by age and, disease activity, then randomly divided into the rhTNFR-Fc (the control group) treatment group in which patients were treated with 25 mg rhTNFR-Fc subcutaneous injection twice per week for 4 months) and rhTNFR-Fc dosage tapering group in which 25 mg rhTNFR-Fc were subcutaneously injected once per week for 4 weeks and then followed by 12.5 mg per week for 4 weeks, then once every 10 days for 6 times. Then the dosage of rhTNFR-Fc dosage of the dosage tapering group (the experimental group) was changed to 12.5 mg subcutaneous injection once every 15 days for another 4 times combined with methotrexate 7.5 mg per week and Salfasalazine 2 g daily and thalidomide 100 mg per night. The second stage started from week 9 to 24. In addition to the 30 cases at the first stage, 42 cases were included based on the same inclusion criteria for stage one. Patients' clinical and laboratory parameters were evaluated at week 0, 4, 8, 16 and 24. Results During the first four weeks, all patients of both control group and experimental group reached ASAS20, 97% (29/30) patients reached ASAS50 in the control group, 83% (25/30) patients reached ASAS50 in the experimental group. At week 8, patients in both groups maintained at 100% ASAS20 improvement, 100% (13/13) patients in the control group reached ASAS50, and that of the experimental group was 97% (29/30), the differences between the two groups were not statistically significant (P>0.05). In the second stage, 72 cases (100%) could achieve ASAS20, 63 cases (88%) achieved ASASSO at week 16. At week 24, 72 cases (100%) remained to achieve ASAS20, 71 cases (99%) achieved ASAS50. The safety and compliance of the two groups were good. Two cases developed infection, one patient had mild elevation of serum transaminase. Conclusion Tapering the dosage combined with DMARDs is an effective and safe approach in the treatment of peripheral joints involvement of ankylosing spondylitis. The compliance of this strategy is good and only few patients have serum transaminase elevation. But attention should be paid to the increased rate of infection.

Objective To investigate the anti-inflammatory effect of Resveratrol on type Ⅱ collagen induced arthritis.Methods Collagen induced arthritis (CIA) animal model was established by subcutaneous injection of type Ⅱ collagen emulsified with incomplete and complete Freud's adjuvant to Wistar rats.Fortytwo rats were successfully induced and randomly divided into 7 groups:the experimental group (A),the leflunomide treatment group (B),the TGP treatment group (C),the methotrexate group (D),the low dose Resveratrol group (E),the medium dose Resveratral group (F) and high dose Resveratrol group (G) and the normal control group (H).Symptoms of arthritis were recorded and selalm levels of the anti-C Ⅱ antibody were detected by ELISA.Results For arthritis index.there was no significant difference between groups E and A,neither between groups C and F.The arthritis index was lower in group G than group C,but both of them were higher than groups B and D.② For serum anti-C Ⅱ antibody level,that of group A was higher than groups B,C,D,F and G.There was no difference between groups A and E,and groups C and F.That of Group G was lower than groups C and E.Conclusion High and medium dose of Resveratrol can relieve foot joints swelling in the CIA rats,but low dose does not have similar effect.The effect of medium dose of Resveratrol iS similar to TGP,but weaker than that of leflunomide.Resveratrol may conduct its anti-inflammatory effect via lowering the concentration of the anti-C Ⅱ antibody in the serum.

Objective To investigate the relationship between plasma homocysteine (Hey) level and ankylosing spondylitis (AS).To analyze the association between the NS,N10 methylenetetrahydrofolate reductase (MTFHR) gene polymorphism and AS.Methods One hundred patients with AS and 60 healthy controls were included in the study.The plasma Hey level was examined by enzyme-linked immunoadsorbent assay and MTHFR gene polymorphism was analyzed by the polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP).Results Compared with heahhy controls,the plasma Hey level in AS patients was significantly higher than that of the controls (P＜0.01).There was no significant difference in the frequen-cies of MTHFR genotype and alleles between AS and the controls (P＞0.05),But the ratio of T/T genotype mutation was different between AS and the controls (P＜0.05).The plasma Hey level of T/T genotype was significantly higher than that of C/T or C/C genotype in AS and the controls (P＜0.01).Logisticalregression analysis indicated that Hey was an independent risk factor for AS (P＜0.01,0R=4.582,95%CI=1.984～10.585).Conclusion The plasma homocysteine level is significantly increased in AS patients.Hyperhomo-cysteinemia is an independent risk factor for AS.MTHFR T/T genotype mutation is an important mechanism of hyperhomocysteinemia and may be related with AS.

Objective To explore the efficacy and safety of intravenous immunoglobulin and glucocorticoid treatment in elderly dermatomyositis patients. Methods Sixty elderly patients with dermatomyositis were randomly divided into two groups: prednisone alone (n= 30, PA) (first 1 mg per kilogram of body weight daily,then decrease the dose according to disease activity), and the combined treatment (n=30,CT,first 1 mg per kilogram of body weight daily, then decrease the dose according to disease activity, and intravenous immunoglobulin 0. 4 g per kilogram of body weight per month for three months). The improvement of clinical symptoms and the occurrence of side effects were observed at the end of month 3. Results The time of muscle strength recovery, remittences of myasthenia and myalgia visual analogue scale(VAS), the decreasing rates of creatine phospho kinase (CPK) level and the dose of prednisone at the end of month 3 were superior in CT group versus PA group (P<0. 05), while no significant differences in the improvement of rash, muscle strength,erythrocyte sedimentation rate(ESR),C-reactive protein (CRP) and side effects between two groups.Conclusions Combination with intravenous immunoglobulin and oral glucocorticoid is a safe and effective treatment for elderly patients with dermatomyositis, it can alleviate symptoms quickly,decrease CPK level and prednisone dose significantly.

objective:To evaluate the sensitivity and predictive value of grey scale and power Doppler ultrasound assessment of bone erosionin disease activity in patients with early rheumatoid arthritis (Ra).
Methods:Fifty-six patients with early Ra underwent blinded sequential clinical, laboratory and ultrasound assessments, and at the same time 20 of these patients underwent X-ray and enhanced MRi. For each patient, 28-joint disease activity score (DaS28), erythrocyte sedimentation rate (eSR), C reactive protein (CRP) and health assessment questionnaire (haQ) were recorded. The presence of bone erosion and synovitis was investigated in 28 joints by gray-scale and power Doppler ultrasonography. The ultrasound joint count and index for active synovitis with power Doppler signal were calculated.
Results:The number of bone erosions detected by ultrasonography was 5.7 times that of X-ray, while both MRi and ultrasonography were consistent (91.5%). The number of synovitis detected by ultrasonography was 1.6 times as much as by physical examination, and consistent MRi (95.7%). PDUS parameters demonstrated a highly significant correlation with DaS28, eSR and CRP, while a negative correlation with haQ.
Conclusion:Grey scale and power Doppler ultrasonography is a sensitive and reliable method to assess bone erosion and inflammatory activity in early Ra. PDUS findings may have a predictive value in disease activity.

Objective: This study was performed to analyze the feasibility of elective nodal irradiation (ENI) for early-stage esophageal carcinoma (EEC), evaluate the curative effect of radiation therapy for EEC, and determine the causes of treatment failure. Methods:Data were collected from 123 patients with esophageal squamous cell carcinoma of clinical T1-2 N0-1 M0 stage. Patients were divided into two groups based on different types of radiation therapy. Among the 123 patients, 102 underwent involved field irradiation (IFI), whereas 21 received ENI. A comparative analysis of patients in the two groups was conducted. Results:In 123 patients, the one-, three-, and five-year overall survival rates were 87.8%, 47.2%, and 36.6%, respectively. By contrast, the one-, three-, and five-year local control rates were 89.4%, 67.5%, and 48.8%, respectively. After comparing the one-, three-, and five-year survival rates in the ENI patients (i.e., 90.5%, 47.6%, and 42.9%, respectively) with those in the IFI patients (i.e., 86.3%, 49.0%, and 35.2%, respectively), no significant difference was found (χ2=0.290, P=0.588 8). The results indicate that ENI possibly decreased nodal metastases (χ2=5.778, P=0.016). Conclusion:Three-dimensional conformal radiotherapy is one of the best therapeutic regimens of radiation for EEC. ENI is possibly effective for preventing regional nodal metastasis. Whether ENI leads to an improved overall survival needs further investigation.
