Objective To detect the levels of anti-gliadin IgA and anti-gliadin IgG antibodies in the plasma of the patients with schizophrenia, and to investigate the association between schizophrenia and anti-gliadin IgA, IgG bodies in a Chinese Han population, and to clarify the effect of gliadin on the occurrence of schizophrenia.Methods The plasma samples were collected from 428 patients with schizophrenia and 555 cases of normal control subjects in a Chinese Han population.The gliadin antibodies in plasma,including IgA and IgG,were tested using a native anti-gliadin ELISA test kit.The positive rates of plasma anti-gliadin IgA,and anti-gliadin IgG were tested by Chi-square test between the patients with schizophrenia and control subj ects. The differences of the levels of anti-gliadin IgA and anti-gliadin IgG were tested by Mann-Whitney U test between the patients with schizophrenia and control subjects.Results Compared with normal control group,the anti-gliadin IgA level and the positive rate of plasma anti-gliadin IgA in patient group were increased significantly(P<0.01),but there were no significant differences of the positive rate and the level of anti-gliadin IgG in plasma between patient and control groups (P>0.05).The anti-gliadin IgA levels in the patients with delusion of observation,delusion of being revealed,delusion of persecution, delusion of j ealousy, delusion of grandeur, incoherence of thinking, illogic thought, bizarre behavior,aggressive behavior,hallucination-delusion syndrome,poverty of thought,emotional blunting/apathy and aboulia were higher than that of the normal controls (P<0.05);the anti-gliadin IgG levels in the patients with delusion of being revealed and delusion of grandeur were higher than that of the normal controls (P<0.05 ). Conclusion Gliadin is associated with the onset of schizophrenia in Chinese Han population, and the plasma antibodies of gliadin maybe play an important rale in the onset of schizophrenia.

Recent studies have found that visfatin is involved in lipid metabolism in patients with nonalcoholic fatty liver disease (NAFLD), and about 25% of NAFLD patients have thyroid dysfunction. It has also been found that visfatin is involved in autoimmune regulation through the autocrine or paracrine pathways, which is associated with the involvement of the thyroid gland in autoimmune regulation of the body. This article preliminarily explores the association of visfatin with thyroid dysfunction in NAFLD patients and points out that the measurement of visfatin may help with the early identification of thyroid dysfunction in NAFLD patients.

Objective To evaluate specific clinical and imaging features of osteogenesis imperfecta V and to improve diagnostic accuracy of this disease. Methods Data of 15 patients with osteogenesis imperfecta type V were retrospectively analyzed for their clinical and imaging features. There were 10 males and 5 females, aged from 1 year and 30 years old (median age,12.5 years ). All 15 patients had plain X-ray, and 4 of 15 had CT. All data were analyzed by 3 experienced deputy chief doctors in OI according to OI V standard. Results X-ray:calcification of the interosseous membrane between radius-ulna was detected in all patients and calcification of the interosseous membrane between tibia-fibula was detected in 2 of 15 patients. Dislocation of the radial head was seen in 13 of 15 patients,bilateral in 9 and utilateral in 4.All patients showed restriction in the pronation and supination of the forearm and restricton in the flexion and extention of the elbow joint. Patients with dislocation of raidal head were associated with large coronoid process and olecranon of the ulna. Hyperplastic callus of the extremities were detected in 7 of 15 patients (7 at femur , 3 at humerus, 1 at tibia.In early stage, hyperplastic callus showed thin cortice, and clear boundares with the diaphysis showing and low density, irregular, mesh-like lamellation inside. In the later stage, there were dense calcification inside hyperplastic callus, and no difference in density with the diaphysis. Diaphysis surrounded by hyperplastic callus had clear boundaries with the hyperplastic callus. No cortical destruction was detected. CT:there were sparse needle-dot calcification inside hyperplastic callus, with the patterns of granular, ring-and-arch,irregular streaky mineralization. The cross section of proximal femoral shaft showed irregular shape , flat square shape and tiny medullary cavity, with no calcification on the edge of hyperplastic callus. CT value:-91 HU inside hyperplastic callus; 283 HU in femoral shaft. Conclusions Interosseous membrane between radius-ulna or tibia-fibula, hyperplastic callus ,dislocation of the radial head are specific features in osteogenesis imperfecta V. X-ray can make a definitive diagnosis of osteogenesis imperfecta V. CT scan is helpful in the differential diagnosis of osteogenesis imperfecta V from osteosarcoma.

Objective To investigate the effects of Xueshuantong injection on levels of inflammatory factors and homocysteine (Hcy) in patients with acute cerebral infarction.Methods 128 patients of acute cerebral infarction who received therapy in the hospital from January 2014 to May 2015 were collected as research objects to retrospectively analyze their clinical materials.According to therapeutic schemes, those patients were divided into control group (n=62) and observation group (n=66).The control group were given conventional treatments, such as anti-platelet aggregation, lipid regulation, maintaining balance of water-electrolyte and acid-base, controlling blood glucose, controlling blood pressure and so on.Besides that, the observation group were given Xueshuantong injection.After two weeks treatment, the curative efficacy, levels of inflammatory factors as high-sensitivity C reactive protein (hs-CRP), tumor necrosis factor α(TNF-α), interleukin 8 (IL-8), Hcy and adverse reactions were compared.Results The total efficacy of observation group was 93.9%, which was statistically higher than that of 80.6%in control group (χ2 =5.166,P=0.023).After treatment, hs-CRP, TNF-α, IL-8 levels in observation group were significantly lower than those in control group (all P<0.05).After one and two weeks treatment, The Hcy level in observation group was statistically lower than that in control group ( all P<0.05 ).The adverse reactions in observation group was 8 cases ( 12.1%), 6 cases ( 9.7%) in control group, with no significant difference between two groups (χ2 =0.196, P =0.658 ). Conclusion Xueshuantong injection is effective in treatment of acute cerebral infarction, which could significantly increase curative efficacy, alleviate inflammatory reaction and reduce level of Hcy with less adverse reactions.

Objective To investigate the safety of the occipital condylar screw with vertical position and evaluate the selection strategy of the posterior approach of the posterior occipital condylar screw in Chinese people.Methods The clinical imaging data of 60 outpatients from September 2013 to September 2015 were retrospectively analyzed,36 male and 24 female,the average age was 41.6±9.2 (range from 25-58),Excluded occipitocervical injury,tumor and deformity patients.We built a three-dimensional digital model and simulated placing screw by utilizing CT data on Mimics software,after that we took the occipital condyle posterior medial and lateral midpoint as the entry point,then made 2 points equidistantly to the midpoint in vertical direction.We put 3.5 mm diameter virtual screws in 4 different conditions:largest cranial angle,smallest cranial angle,longest screw path and shortest screw path.Then we assessed the anatomical relationship between the screw and the hypoglossal canal or the atlanto-occipital joint by a three-dimensional window and measured the cranial angle,medial angle and length of screw path,then calculated the safety angle of the cranial angle,the successful rate of setting screw,and compared the safety of different screw points by 3-Matic software.Results 120 occipital condyles were obtained from the CT data of 60 patients by Mimics software.There was no significant difference in the data of the cranial angle,medial angle,safety range and length between both left and right sides.The obtained safe cranial angle of each point respectively was 20.9°±6.0° (lowest point),17.0°±6.2° (middle point),and 11.6°±7.1°(top point),obviously the largest angle was in the lower point and the smallest was in the top point.The difference was statistically significant.We then acquired the successful rates of different cranial angle of each point,the highest successful rate was 99.17％,96.67％,74.17％ in lowest,middle and top point when cranial angle were 3°or 4°,3°and 0°respectively.The successful rates of lower point and niddle point were significantly higher than the top point,and the difference was statistically significant.The medial angle parameters obtained were 34.41°±2.59°on left and 34.06°±2.44°on right,and there was no significant difference.The length parameters of the longest screw path acquired were 23.09± 1.47 mm,22.84± 1.40 mm and 23.15± 1.45 mm at top,middle and lowest entry point.The average value of shortest screw path of each point was 21 mm,and there was no significant difference among every entry point.Conclusion Among the occipital condyle posterior screw entering points,selecting the lower point can improve the success rate and safety;the change of nail enter point in the vertical direction has little effect on the length of the nail.We can increase the safety and reduce the risk of occipital condylar screw placement as far as possible through the three-dimensional digital technology.

AIM: The effect of low dose radiation (LDR) with different doses of X-rays on apoptosis and its related gene P53 expression were studied in spermatogenic cells of male Kunming mouse testis. METHODS: The different kinds of spermatogenic cells were separated using density gradient centrifugation and their apoptosis was measured by flow cytometry. At meantime, P53 protein and P53 mRNA was measured with immunohistochemical SABC and in situ hybridization, respectively. RESULTS: The apoptosis in all kinds of spermatogenic cells induced by LDR had a remarkable regularity. When the doses were 0 025 and 0 05 Gy, spermatogone apoptosis was domaint. With the increase in irradiation dose (0 075-0 2 Gy), spermatocytes also showed an apoptotic change, but the apoptotic percentage of spermatogonia was significantly higher than that of spermatocytes. Moreover, the apoptosis of spermatids and spermatozoa scarely occurred after LDR. P53 protein expressed in spermatogonia and spermatocytes in varying degrees, and the former was significantly higher than that of the latter after LDR. With the increase in irradiation dose, P53 protein expression showed a upregulated tendency, but that of spermatids and spermatozoa scarcely occurred. P53 mRNA primarily expressed in spermatids and spermatocytes when the dose was 0 025 Gy. With the increase in irradiation doses (0 05-0 2 Gy), that of spermatogonia also showed an enhancement. P53 mRNA expression in spermatogonia and spermatocytes showed a remarkable dose-effect relationship. CONCLUSION: The apoptosis of spermatogenic cells was selectively induced by LDR of X-rays, which had remarkable the dose-effect and time-effect relationships. The mechanism of the selective apoptosis in spermatogenic cells by LDR is closely related to the upregulation of P53 .

Objective To evaluate the effect of nurse-led follow-up on medication adherence and quality of life for breast cancer patients receiving adjuvant hormonal therapy.Methods A randomized controlled trial was conducted with 157 patients in the intervention group and 154 in the control group.A self-design web-database medication monitoring platform was designed for managing patients such as texting,reminding and mailing.Participants were randomized to follow-up care as usual(yearly outpatient clinic visits) or nurse-led telephone follow-up(monthly consultation with structured intervention).Telephone follow-up was performed by four trained breast care nurses (BCN) and consisted of a semi-structured interview including managing the side-effects of endocrine therapy,compliance with hormonal therapy and an open discussion of these issues.Patients' medication adherence and quality of life were evaluated by Morisky Medication Adherence Questionnaire(MAQ) and FACT-B at baseline and 3,6 18 and 24 months,respectively.Results The Nurse-led telephone follow-up did not significantly improve the quality of life(P＞0.05).MAQ score in the intervention group was significantly greater than that in the control group(P＜0.05) at 3,6,18 and 24 months.Conclusion Nurse-led follow-up using computer-based monitoring system can improve patients' medication adherence,but there is no obvious increase in quality of life.
