ObjectiveTo study the impact of stroke on elderly's mental status.Methods71 elderly inpatients aged between 60 to 90 who suffered stroke(31 cases) or not(40 cases) were assessed the mental status as a whole, the evaluation of comprehension of linguistic information,and non-verbal reasoning abilities using Mini Mental State Examination(MMSE), Token Test and Raven Test.The relationships between these cognitive aspects and stroke was also analysed.ResultsThere were 68% of elderly suffering dementia symptoms in stroke group which was much higher than Non-stroke group (15%).The correlation between MMSE and Token is more close than the correlation between MMSE and Raven in stroke group. The correlations among MMSE, Token and Raven were significant different between stroke and Non-stroke groups. There is a positive correlation coefficient between age and Token scores in dementing patients; whereas a closer relationship between age, education level and Raven in Non-stroke group was found. This implied the impacts of stroke on the time-course of mental degeneration.Conclusions stroke can interrupt normal mental structure and speed up the process of degeneration of cognitive functions. Semantic dysfunction might manifestation earlier than non-linguistic functions. Token is more sensitive than Raven in detecting dementia symptoms of stroke type.

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.

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

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.

[Objective] To establish a method for the determination of geniposide in Jinzhi Jieyin Gargle by RP- HPLC. [ Methods ] SupelcosilTM LC - 18 (150 mm ?4.6 mm, 5?m) was used as the analytical column, methanol - water -phosphoric acid (25∶75∶0.12 ) as mobile phase and the detection wave - length at 240 run. [Results] Within the range of 0.175-1.84?g, geniposide showed a good linearity ( r = 0.9999 ). The average recovery was 99.93%(n=5, RSD = 1.16%). [Conclusion] This method can be used for the quality control of Jinzhi Jieyin Gargle.

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

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.

After acute myocardial infarction, how realizes revasculadzation of the infarct area as well as prolongs the postponement left ventricle reconstruction and restores heart normal contraction function has been the hot spot. The research demonstrated that the transplanted stem cells may be in field planting of the heart infarct region, simultaneously through nutrition effects of secreting vascular endothelial cells and differentiation into myocardial cells, vascular endothelial calls, and can improve ventricle reconstitution and recovery cardiac function. However, stem call effects on myocardial infarction have close correlation to stem call tissue source. Various preconditioning also can affect repair of stem cells. Meanwhile, choice of suitable stem cell donors and recipients, correction of transplanted window and pathway are key factors for obtaining good clinical curative effects.
