OBJECTIVETo study the synergistic effects of electroacupuncture on the treatment of knee osteoarthritis after arthroscopic debridement.

METHODSFrom May 2008 to July 2010, 78 patients with knee osteoarthritis were randomly divided into two groups. There were 42 patients in the experimental group, including 16 males and 26 females, ranging in age from 41 to 63 years, with an average of (53.62 +/- 6.53) years; the disease course ranged from 8 to 24 months, with an average of (10.35 +/- 6.42) months. The patients were treated with arthroscopic debridement combined with electroacupuncture after operation. There were 36 patients in the control group, including 14 males and 22 females, ranging in age from 40 to 62 years, with an average of (54.34 +/- 7.67) years; the disease course ranged from 6 to 25 months, with an average of (11.94 +/- 5.13) months. Those patients were treated only with arthroscopic debridment. All the patients performed isometric quadriceps femoris contraction exercise and knee flexion and extension activities after operation. The visual analog scale(VAS) score and Lysholm knee score were used to evaluate the therapeutic effects.

RESULTSAll the patients were followed up, and the duration ranged from 12 to 30 months, with an average of 15.6 months. At the final follow-up, VAS score was significantly decreased, and the Lysholm score, except for the item demanding for support, significantly increased, compared with those before surgery respectively in both groups. There was significant difference in VAS score between two groups after treatment. As to Lysholm score, there were significant differences in limp, pain, swelling, stair activity and squat, but there were no significant differences in items of interlocking and instability between two groups after treatment.

CONCLUSIONElectroacupuncture can effectively improve the clinical symptoms and knee joint's motor function of knee joints in patients with knee osteoarthritis, as well as the synergistic effects on the treatment of knee osteoarthritis after arthroscopic debridement, leading to a much better long-term therapeutic effect with respect of improving the function of knee joint. This therapy, combined with traditional Chinese medicine and Western Medicine,is worth of clinical application in the treatment of knee osteoarthritis.

OBJECTIVETo retrospectively analyze therapy comparison between hinged external fixator combining with internal fixation, soft tissue repair and plaster fixation after routine surgery for terrible triad of the elbow.

METHODSFrom January 2003 to June 2011,26 patients with terrible triad of the elbow (posterior dislocation associated with fracture of both the radial head and the ulnar coronoid process) were treated respectively by unilateral hinged external fixator and plaster fixation. Fourteen patients were treated with external fixator combining with internal fixation, soft tissue repair and reconstruction, including 8 males and 6 females,ranging in age from 20 to 62 years with an average of (33.60 +/- 8.53) years. The mean time of fixation was 7.5 weeks (ranged, 6 to 8 weeks), and forearm rotation exercise was performed after the first day of operation, elbow flexion and extension activities after 4 to 6 days. Twelve patients were treated with plaster external fixation combining with open reduction and internal fixation,including 8 males and 4 females,ranging in age from 21 to 63 years with an average of (34.80 +/- 7.41) years. The mean time of plaster fixation was 30.4 days, and functional exercise was carried out after 4 to 6 weeks of plaster removal. JOA assessment score were used to evaluate the elbow joint function.

RESULTSAll the patients were followed up, and the duration ranged from 12 to 36 months,with an average of 18.6 months. The mean time of fracture healing was (8.6 +/- 3.1) weeks in plaster group and (9.0 +/- 2.7) weeks in fixator group, with no statistical difference between the two groups (t =1.47, P > 0.05). The function and are of motion in plaster group and fixator group showed significant difference. While the pain, articular instability and deformity showed no statistical difference. The total assessment score between two groups indicated markedly difference (t = -2.66, P < 0.01).

CONCLUSIONHinged external fixator can enhance lateral stability of elbows,benefit the reduction of fracture dislocation, guarantee early and safe functional exercise, prevent elbow stiffness, and reduce heterotopic ossification. In treating terrible triad of the elbow, the hinged external fixator is superior to other therapies with respect of improving the function of elbow joint.

The dislocation of acromioclavicular joint is a common type of dislocation in clinic. Non- operative therapy has usually been the main traditional method to deal with it. However, with research on its mechanism and classification going further and further, more and more scholars have been inclined to apply surgical methods in recent years. In this article, we discuss briefly the non- operative and operative methods for dislocation of acromioclavicular joint

To explore the application of fetal DNA in maternal plasma for noninvasive prenatal diagnosis, the DNA template was extracted by hydroxybenzene-chloroform from 44 maternal (7-41 weeks) plasma. The Fetus-derived Y sequence DYZ-1 gene (149bp) was chosen to be amplified by PCR. The fragment was identified in all the plasma of male bearing pregnant women with the diagnostic accordance rate being 100.00%. Two of the 22 female bearing pregnant women had false positive results. Among the 44 pregnant women, the diagnostic accordance rate was 88.89% at early pregnant stage, 100.00% at medium pregnant stage, and 96.55% at late stage respectively. The final accuracy of 95.45% was obtained in all cases. It was concluded that by means of hydroxybenzene-chloroform extraction the authors of this article promoted the concentration and purity of the DNA template, and diagnosed more accurately. The results showed that free fetal DNA in the maternal plasma could be regarded as the gene resource for noninvasive prenatal diagnosis.

Objective To investigate the relatiouship between obsessive-compulsive symptoms and schizophreuia symptoms in schizo-obsessive patients, and to address the feature of insight. Methods Fifty-two cases of schizophrenia with obsessive-compulsive symptoms were assessed by Yale-Brown obsessive-compulsive scale( YBOCS) and positive and negative syndrome scale(PANSS). Results The Y-BOCS overall severity score(26.7 ±4.78)was not correlated with the PANSS total score(86.9 ± 13.4)( r=0. 191 , P＞0.05), there was significant association between the insight score( 2.65 ±0.81 )and the PANSS total score( 86. 9 ± 13.4 ) ( r = 0. 416, P＜0. 01 ),and the same between the insight score( 2.65 ± 0. 81 )and the Y-BOCS overall severity score(26.7 ±4.78 ) ( r = 0. 387, P ＜ 0. 01 ). Conclusion Obsessive-compulsive symptoms and schizophrenia symptoms in schizo-obsessive patients are not correlated, obsessive-compulsive symptoms are not inherent symptoms of schizophrenia. As insight is correlated with both obsessive-compulsive symptoms and schizophrenia symptoms, anti-psychotic along with anti-compulsive treatment should be able to effectively improve the insight of schizo-obsessive patients.

Objective To evaluate the diagnostic value of CT manifestations of the lung in localized Wegener′s granulomatosis(LWG). Methods CT findings of the lung in 11 patients with LWG verified by pathology were retrospectively analyzed. Results All the cases presented with multiple nodules of soft dense varying from 0.5 cm to 3.0 cm in diameter which distributed in the lung. Cavities were commonly seen in the larger nodules. Seven cases showed the wedge-shaped lesions with their bases situated externally on the pleural surface and with their convex apices directed at the hilum. The massive shadow with blurred margins was found in 4 cases. The nodules and wedge-shaped lesions demonstrated peripheral enhancement. Some of them presented with “vascular sign”. Conclusion The CT features of LWG were multiple nodules and cavities within nodules coexisting with wedge-shaped lesions, peripheral enhancement of nodules, and “vascular sign”. The law of change and the features of enhancement were relatively characteristic to the diagnosis of LWG.

Objective To study the variable number tandem repeats (VNTR) polymorphism in intron 4 of the endothelial nitric-oxide synthase (eNOS) gene and its relationship with plasma NO in pregnancy induced hypertension (PIH). Method The VNTR polymorphism in intron 4 of the eNOS genes of PIH and healthy control pregnant women were detected by PCR. The plasma level of NO~(3-)/NO~(2-) was measured by spectrophotometer, which was used as the index of NO synthesis.Data were analyzed according to the different type of genotypes and allelic gene frequency. Results The PIH group showed significant higher frequency of VNTR 4a allele and 4a/4b+4a/4a genotype than those of the control (16.00% vs 7.50%,P
