Objective To explore the cognitive function of the theory of mind(TOM) in early-onset schizophrenia from faux pas recognition and belief understanding dimensions.Methods 41 early-onset schizophrenias (EOS) and 40 normal adolescents were interviewed by the Chinese version of faux pas recognition task and theory of mind picture-sequencing task(ToM-PST),then early-onset schizophrenias cognitive features were analyzed.Results ①In faux pas recognition task,compared with healthy subjects,EOS showed significantly less total scores (16.11±6.34 vs 20.86±7.79,P＜0.05)and subscores of understanding faux pas questions (9.88±4.11 vs 13.27± 6.07,P＜0.05).In faux pas recognition scores(6.72±2.60vs 7.58±2.20) and control questions(9.83±0.44vs 9.97± 0.16) had no statistically significant difference (P＞0.05).②In ToM-PST task,early-onset schizophrenic patients also had significantly less total score(17.29±3.38 vs 21.48± 1.73,P＜0.01),subscores of understanding first order belief,first order error belief,second order belief,second order error belief,third order error belief,sense of reality,reciprocity,fraud,detecting fraud compared to normal controls had significant difference (all P＜ 0.05 or 0.01).③ The correlation between clinical course time and PANSS score and its subscores of the theory of mind picture-sequencing and faux pas task was non-significant(P＞0.05)except the subscores of understanding the first order belief (P＜0.01).Conclusion The theory of mind is apparent damage in early onset schizophrenia and non-significant correlation is found with psychiatric symptoms.

Objective To explore the theory of mind (TOM) between adolescent with schizophrenia and normal adolescent from hot TOM and cool TOM.Methods 37 adolescent schizophrenias and 25 normal adolescents were interviewed with the Chinese version of YONI task, Reading the Mind in the eyes test and series of tests,then analyzed with adolescent schizophrenias cognitive features.Results ① Compared with the control group (83.16± 10.07),the scores of YONI task in the adolescents with schizophrenia (74.30 ± 11.44) had statistically significant difference (t=-2.983,P＜0.05),mainly the statistically significant difference existed in the groups in cool and hot TOM.②The differences between positive subtype (69.85± 12.66) and negative subtype (78.18±8.92) in scores were significant(t=-2.104,P＜0.05),especially in the hot TOM.③In Reading the Mind in the eyes test,there was no statistically significant difference in scores(t=0.982,P＞0.05) between the control group (17.59±3.13) and the group of adolescents with schizophrenia(18.42±2.98).Conclusion The adolescents with schizophrenia damage in hot TOM and cool TOM.The adolescents with schizophrenia in positive subtype are worse than the negative subtype,especially in the hot TOM.

Conjunctiva goblet cells are spread out within a stratified epithelium, and keep ocular surface homeostasis by secreting mucin.Previous research has shown conjunctiva goblet cells can secret mucin, remove debris and modulate ocular surface immune function.In this review, we will focus on biological characteristics of conjunctiva goblet cells and the effect of key factors SAM pointed domain Ets factor(SPDEF) on differentiation and function of conjunctiva goblet cells, and further understand relationship between goblet cells and eye health.

To evaluate the automated segmentation algorithm for detection of intra - retinal layers to process images obtained from ultra- high resolution optical coherence tomography ( OCT ) . Graph theory and the shortest path search based on dynamic programming were applied to automatically segment the 8 intra - retinal layers. We experimentally verified the accuracy and reliability of the algorithm. The results showed that the intra-retinal layer boundaries between automated and manual segmentations matched well. The algorithm successfully segmented the intra- retinal layers in glaucoma, high myopia, and retinitis pigmentosa patients. The proposed automatic segmentation for intra-retinal layers provides a promising tool for quantitative analysis in clinical diagnosis and treatment.

Objective:To explore the effect of group psychotherapy on damage of theory of mind (TOM) in patients with early-onset schizophrenia.Methods:Totally 60 patients with early-onset schizophrenia were included and divided into the intervention group (n ＝ 30) and the health education group (n ＝ 30).The patients in the intervention group were offered 10 twice a week 2-hour sessions of group psychotherapy,and those in the control were offered group health education twice a week.All participants completed baseline measures and post-intervention measures with the Eye Emotion Recognition and Theory of mind Picture-sequencing Task (TOM-PST).Results:Totally 23 patients in the intervention group and 29 patients in the health education group finished the post-intervention measures.After 5-week intervention,subscores of sad and fear and total score of emotion recognition,total score of TOM-PST,understanding first order error belief,second order error belief,third order error belief,sense of reality,detecting fraud compared to baseline had statistically significant difference in intervention group.In health education group,subscores of joy emotion recognition,understanding first order error belief,third order error belief,total score of TOM-PST compared to baseline had statstically significant difference.The patients with group psychotherapy got higher scores of total score of TOM-PST and understanding second order error belief and third order error belief than the health education group after 5-week intervention (P ＜ 0.05).Conclusion:This study suggests the group psychotherapy could partially improve theory of mind with early-onset schizophrenia,and promote the recovery of social cognition.

OBJECTIVETo observe the effect of Yiqi Huoxue Qingre Huashi Recipe (YHQHR, a recipe capable of supplementing qi, activating blood, clearing heat, and dissipating dampness) on ulcer healing and Helicobacter pylori (Hp) eradication rate in Hp positive peptic ulcer patients, and to explore coccoid Hp occurrence in the eradication.

METHODSTotally 80 Hp positive peptic ulcer patients were assigned to the treatment group and the control groups by random digit table, 40 in each group. All patients received standard triple therapy of Western medicine for 2 successive weeks. Those in the control group additionally took omeprazole enteric coated tablet, 20 mg each time, once per day for 4 successive weeks. Those in the treatment group additionally took YHQHR, twice per day for 6 successive weeks. The ulcer healing was observed and recorded by gastroscope after discontinued medication of 14 days. The effective rate of ulcer healing under endoscope was statistically calculated. Rapid urease test (RUT) was performed in one small piece of tissue from corpora ventriculi and sinuses ventriculi using 14C breathe test (UBT). Gastric juice was collected from the stomach. Hp urease gene amplification test (urea A-PCR) was performed in living tissue from gastric antrum. Results obtained from the above three test methods were recorded and assessed to decide the final eradiation rate. Gastric mucosa tissue was observed under electron microscope,attempting to find non-eradicated Hp, which was further observed.

RESULTSThe total curative effect under gastroscope was 97.5% (39/40 cases) in the treatment group, obviously higher than that in the control group (80.0%, 32/40 cases) (P < 0.05). The eradication rate of Hp was 75.0% (30/40 cases), obviously better than that of the control group (52.5%, 21/40 cases) (P < 0.05). The total positive Hp numbers after treatment was 14C UBT (12), RUT (8), and urea A-PCR (27), respectively. The Hp positive rate detected by 14C UBT and RUT was lower than the Hp positive rate detected by urea A-PCR (P < 0.05). Rod-like and coccoid Hp bacteria could be observed under electron microscope.

CONCLUSIONYHQHR combined standard triple therapy was more effective than standard triple therapy alone in promoting ulcer healing and elevating the eradication rate of Hp.

OBJECTIVEThe influence of processing methods on chemical constituents in Radix Paeoniae Alba was observed.

METHODA HPLC method was used for analyzing the changes of eight major constituents, namely gallic acid, paeoniflorin sulfonate, catechin, paeoniflorin sulfonate, albiflorin, paeoniflorin, benzoic acid, pentagalloylglucose and benzoylpaeoniflorin, with the three processing procedures of decorticating, boiling and fumigating by burning of sulphur. Analysis was performed using a Zorbax SB-C18 column (4.6 mm x 250 mm, 5 microm) with the mixture of acetonitrile (A) and 0.015% phosphoric acid solution as mobile phase in gradient mode. The detection wavelength was set at 230 nm and the column temperature was at 30 degrees C.

RESULTExcept for gallic acid and pentagalloylglucose, the other constituents decreased during procedure of decorticating and boiling. Fumigating by burning of sulphur would produce a new compound, paeoniflorin sulfonate, which was a byproduct from the reaction of paeoniflorin with SO2.

CONCLUSIONThe significant changes were produced in chemical constituents of Radix Paeoniae Alba during three processing procedures. Therefore, the processing of Radix Paeoniae Alba should be strictly controlled and standardized.

OBJECTIVETo study the effect of vascularized fibular graft on large defects of long bones and the monitoring method for the vascular status of the grafted fibula.

METHODSFrom March 1988 to February 1998, 30 patients with long bone defects over 6 cm in length received vascularized fibular graft including a monitoring island flap in our department to monitor the blood circulation of the fibulae.

RESULTSMonitoring island abnormalities were indicated in 6 flaps, which accurately gave the alarm of the circulation crisis of the fibular graft. Surgical exploration was performed timely and the blood supply was recovered instantaneously. All the bone defects were healed at 6 months postoperatively. After 4 years of follow-up, all the grafted fibulae were thickened and were just like tibiae.

CONCLUSIONSA monitoring island flap is a satisfactory method for repairing large defects of the long bones and a reliable method for assessing the vascular status of the grafted fibulae.

UNLABELLEDTo screen and analyze the apoptosis- and proliferation-related genes in human nasopharyngeal carcinoma (NPC).

METHODSAccording to gene ontology classification, the abnormal expressions of the genes related to cell apoptosis and proliferation were identified in the NPC gene chip data. The cell apoptosis- and proliferation-related genes expressed in each of the 3 stages, as defined by the tree model for the pathogenesis and progression of NPC, were screened, and with literature review, their distribution in the tree model were analyzed.

RESULTSNineteen genes related to cell apoptosis were found in NPC, among which 9 were down-regulated (such as DNASE1L3) and located in the chromosome deletion regions, and 10 were up-regulated (such as DEDD) in the chromosome amplification regions. Twenty-one cell proliferation-related genes were identified, including 8 down-regulated genes (such as TUSC2) in the chromosome deletion regions and 13 up-regulated ones (such as EMP1) in the chromosome amplification regions. In the chromosome deletion regions, the down-regulated cell apoptosis-related genes participated mostly in inducing and regulating cell apoptosis, and the up-regulated cell proliferation-related genes in the chromosome amplification regions were mostly associated with the positive regulation of cell proliferation.

CONCLUSIONNPC occurs possibly through two pathways by inhibiting cell apoptosis or by promoting excessive cell proliferation.
