Objective To investigate the eyelid and orbital development of congenital microphthalmia. Design Prospective case se- ties. Participants 23 eyes of 23 patients with congenital microphthalmia aged from 6 months to 78 months. Methods The parameters of palpebral fissure length (PFL), palpebral fissure height(PFH) were measured in all patients. Also, combining the computer tomography (CT) imaging with the computer-aided design system, the anteroposterior axis of eyeball and orbital volumn were calculated automatically. To e- valuate the influence factor of eyelid and orbital growth, correlations between age, anteroposterior axis of eyeball and PFL, PFH, orbital volumn were analyzed. Main Outcome Measures PFL, PFH, anteroposterior axis of eyeball and orbital volumn. Results The PFL, PFH, anteroposterior axis of eyeball and orbital volumn in micro-side were (16.44?3.24) mm, (2.47?1.48) mm, (11.99?3.33) mm, (14.19?2.37) ml respectively. These parameters above were all significantly smaller than the unaffected side (all P=0.000). Moreover, orbital volume showed a strong linear correlation with the anteroposterior axis of eyeball and age(r=0.62, 0.63;p=0.037, 0.035). Both PFL and PFH were corelated with the anteroposterior axis of eyeball (r=0.54, 0.53; P=0.030,0.034), while showing no significant difference with age. According to the an- teroposterior axis of eyeball, two groups, including group less than or equal to 12 mm (10 cases) and group more than 12 mm (13cases), whose PFL,PFH and orbital volumn were (13.50?1.97) mm, (1.08?0.66) mm; (12.73?0.95) ml, (18.20?2.49) mm; (3.30?1.16) mm, (15.05?2.57) ml, respectively. They had statistically significant difference in PFL, PFH and orbital volumn (P=0.001, 0.003,0.024). Conclusion The development of eyelid and orbit with congenital microphthalmia is obviously retarded. The smaller the eyeball is, the much worse in- fluence in eyelid and orbital growth is. The intervention therapy in early stage as far as possible is fundamental approach in simulating the eyelid and orbital development, or preventing and reducing the incidence of orbital deformity.

Objective To explore the effect of prevention and treatment of external application of Algoplaque for controlling phlebitis caused by peripheral indewelling needle in vein for patients. Methods This research was divided into two parts,prevention and treatment. As for prevention research,patients were randomly divided into the experimental and the control groups,each group included 30 patients. In the experimental group,we applied directly external application of Algoplaque at the upper of needle puncture site of the vein and nearby the eye. In the control group,we applied the film directly to fix the indwelling needle. As for the treatment research, it was carried out in patients with occurred phlebitis, who were randomly divided into two groups,the experimental group included 30 cases of patients and the control group included 28 cases of patients. Observation time was one to five days. Results The incidence of phlebitis in the experimental group of prevention research was 23%, in the control group it was 90%. The incidence of phlebitis in the experimental group was significantly lower than that of the control group. The effective rate in the experimental group of treatment research was 96.7% and it was 67.9% in the control group. The difference was very significant. Conclusions External application of Algoplaque can effectively control phlebitis caused by peripheral indewelling needle in vein.

Objective To investigate the empathic abilities and the association between empathic abilities and executive function in schizophrenic patients. Methods Empathy with the Interpersonal Reactivity Index-C (IRI-C) and executive function with Wisconsin Card Sorting Test (WCST) , Stroop Color-Word Task (Stroop), Spatial n-back Task (n-back) were applied to 74 schizophrenic patients and 69 healthy controls. Results Compared with healthy controls, schizophrenic patients showed significantly lower total scores ((46. 8 ± 10. 0) vs (51.5 ±9.7), P<0.01),and subscores in Perspective Taking ((9.5 ±4.2) vs (12.2 ±3.9) , P<0. 01), Fantasy ((12.5 ±4.2) vs (15.5 ±3.8), P<0.01) and Empathic Concern((15. 9 ±4.2) vs (17. 3 ±3.4), P< 0.05) ,but higher subscore((8.8 ±5. 1) vs (6.5 ±3.7), P<0.01) in personal distress of IRI-C. A significant difference(P<0.01) were fund on the scores of WCST, Stroop task and n-back task between schizophrenic patients and healthy controls. Pearson correlation analysis showed that the total scores of IRI-C was negatively correlated with the response administered (Ra), the number of responses errors (Re) and non-perseverative errors (nRpe) of WCST (r= -0.293, r= -0.253, r= -0.272, P<0.05) respectively, that empathic concern sub-score of IRI-C was negatively correlated with Ra, Re, perseverative responses (Rp) and perseverative errors (Rpe) of WCST (r= -0.326, r= -0.300, r= -0.294, r= -0.287, P<0.01 -0.05) respectively , but positively correlated with Rfp. of WCST (r=0.279, P<0.05), and that the fantasy subscore of IRI-C was negatively correlated with the reaction time of B part(r= -0.299, P<0.01) and C part (r= -0.322, P<0.01) of the Stroop task. Conclusion Schizophrenics have a general impairment of empathy and executive function,and affective empathy is related to the executive function, suggesting that the impairment of executive function maybe the one of pathological mechanism for the empathic deficit of patients with schizophrenia.

OBJECTIVETo investigate the accumulation of advanced glycation end products (AGE) and the inflammatory response of skin and wound in diabetic patients, and to analyze their relationship in vitro.
METHODSHistological staining and immunohistochemical staining was respectively performed on skin and wound tissue specimens collected from 10 patients with Type II diabetes mellitus (diabetes group) and 12 non-diabetic patients with skin injury (control group) to observe the arrangement of collagen and the distribution of inflammatory cells, and to determine the expression levels of AGE and its receptor (RAGE). Malondialdehyde (MDA) levels in skin and wound tissue homogenates were assayed by enzyme-linked immunosorbent assay. In vitro, human neutrophils were isolated and treated with RPMI-1640 culture medium or that containing AGE-human serum albumin in the concentration of 0.315, 0.625, 1.250 mg/mL, and they were identified as normal control (NC) group, low concentration (L) group, moderate concentration (M) group, and high concentration (H) group. Cell viability in each group was determined by MTT colorimetric assay, and the reactive oxygen species (ROS) in cell was measured with 2', 7'-dichlorofluorescein-diacetate. Data were processed with t test.
RESULTSCompared with those of skin in control group, collagens of skin tissues in diabetes group atrophied and disorderly arranged. Inflammatory cells in wounds in diabetes group were dispersed, in which collagens arranged loosely and irregularly, as compared with those of wounds in control group. Expression levels of AGE and RAGE of skin in diabetes group were higher than those in control group. In diabetes and control groups, especially in diabetes group, the numbers of RAGE-positive cells in wound tissue were more than those in skin tissue. Large amount of inflammatory cells with positive expression of RAGE were observed in diabetes group. MDA level of skin and wound tissue in diabetes group was respectively (6.3 ± 1.0), (7.1 ± 2.4) nmol per milligram protein, which were obviously higher than those in control group [(2.9 ± 1.0), (3.6 ± 1.4) nmol per milligram protein, with t value respectively 8.017, 4.349, P < 0.05 or P < 0.01]. Cell viability and ROS levels in neutrophils were increased in L, M, and H groups [(59 ± 8)%, (77 ± 5)%, (67 ± 6)% and 1.67 ± 0.14, 2.13 ± 0.17, 3.48 ± 0.48] as compared with those in NC group [(34 ± 5)% and 0.58 ± 0.06, with t value respectively 7.195, 14.890, 11.130 and 20.195, 24.905, 16.864, P < 0.05 or P < 0.01].
CONCLUSIONSAbnormal oxidative stress in diabetic skin leads to an atypical origin of wound repair. AGE-RAGE effect is a critical mediator for oxidative stress in diabetic wound tissue during wound healing.

AIMTo assess whether exogenous estradiol has any effect on migration of primordial germ cells (PGCs) in the chick.
METHODSFertilized eggs were treated with 17beta-estradiol (E(2)) (80 microg/egg) at stage X (day 0 of incubation), stages 8-10 (incubation 30 h) and 13-15 (incubation 55 h). Controls received vehicle (emulsion) only. Changes in PGC number were measured on different days according to developmental stages.
RESULTSIn male right gonads, but not in female left gonads, at stages 28-30 (incubation 132 h) significant decreases in the mean number of PGCs aggregating were observed compared with the controls (P < 0.05) while the total PGC number in the right and left gonads at each stage did not change (P > 0.05).
CONCLUSIONThe present study provides evidence that E(2) has significant effects on the localization of PGCs in male right, but not female left, gonads of chicken embryos at stages 28-30, compared with controls.

BACKGROUNDMiR-34a dysregulation has been implicated in tumorigenesis and progression of gastric cancer, but its role in prognosis of patients with gastric cancer remains unknown. The aim of this study was to investigate the expression and prognostic significance of miR-34a in gastric cancer patients after radical gastrectomy.
METHODSQuantitative real-time polymerase chain reaction was performed to detect the expression of miR-34a in human gastric cancer cell lines and tissues in 76 patients with gastric adenocarcinoma from China. Results are assessed for association with clinical features and overall survival (OS) using Kaplan-Meier analysis. Prognostic values of miR-34a expression and clinical outcomes were evaluated by Cox regression analysis. A molecular prognostic stratification scheme incorporating miR-34a expression was determined using receiver operating characteristic analysis.
RESULTSThe results show that the expression level of miR-34a was decreased in human gastric cancer cell lines and tissues, and down-regulated expression of miR-34a was associated with Lauren classification (P = 0.034). Decreased miR-34a expression in gastric cancer tissues was positively correlated with poor OS of gastric cancer patients (P = 0.013). Further multivariate Cox regression analysis suggested that miR-34a expression was an independent prognostic indicator for gastric cancer (P = 0.027). Applying the prognostic value of miR-34a expression to tumor node metastasis (TNM) stage system showed a better prognostic value in patients with gastric cancer than miR-34a expression (P = 0.0435) or TNM stage (P = 0.0249) alone.
CONCLUSIONThe results reinforce the critical role for the down-regulated miR-34a expression in gastric cancer and suggest that miR-34a could be a prognostic indicator for this disease.

The Bacillus subtilis Sac B gene with the vacuolar targeting signal sequence driven by 35S promotor was transferred into Lespedeza thunbergii by Agrobacterium mediated method. Total 62 Kan-resistant plants were obtained, of which 5 plants were proved to be transgenic plants. The transgenic plants were characterized by PCR amplification, PCR-Southern hybridization and RT-PCR. The physiological assay results showed that the transgenic plants were more tolerant to stress than the controls under the condition of 200mmol/L NaCl and 5% PEG, respectively, and that the content of soluble sugar in trnsgenic plants was significantly higher than that of controls in the period of tests (5-15 days) under salt and PEG stress.

BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) and bone marrow mononuclear cells(BMMNCs) have been both used to treat spastic cerebral palsy. However, the differences in their therapeutic effects remain unknown. OBJECTIVE: To compare the therapeutic effects of BMMSCs and BMMNCs in cerebral palsy children as well as on fine motor function. METHODS: 105 children with spastic cerebral palsy were enrolled and randomly assigned to three groups: BMMSCs group, BMMNCs group and control group. Patients in the two transplantation groups received four intrathecal cell injections, and those in the control group received Bobath therapy, twice a day, for consecutive 3 weeks. The Gross Motor Function Measure (GMFM) and Fine Motor Function Measure (FMFM) were used to evaluate the therapeutic efficacy at 3, 6 and 12 months after transplantation. RESULTS AND CONCLUSION: At 3 months after cell transplantation, scores in A dimension of GMFM and in A, C dimensions of FMFM in BMMSC group were all superior to those of BMMNC group and control group (P < 0.05). At 6 months after cell transplantation, scores in A, B dimensions of GMFM and in A, B, C, D and E dimensions of FMFM in BMMSC group were better than those of BMMNC group and control group (P< 0.05), and total scores of GMFM and FMFM were also better in the BMMSC group (P < 0.05). At 12 months after cell transplantation, scores in A, B and C dimensions of GMFM and A, B, C, D and E dimensions of FMFM scores in BMMSC group were all superior to those of BMMNC group and control group (P < 0.05) as well as the total GMFM and FMFM scores. There were six cases of low intracranial pressure headache in BMMNC group and six cases of low-grade fever in BMMSC group. In summary, both BMMSCs transplantation and BMMNCs transplantation are safe, effective and feasible for the treatment of spastic cerebral palsy in children, and moreover, BMMSCs transplantation is a better method than BMMNCs transplantation to improve gross and fine motor functions of spastic cerebral palsy children.

Objective:To analyze the relationship between serum antibody titers, clinical characteristics, and prognosis in patients with encephalitis induced by anti leucine-rich glioma inactivated 1 (LGI1) antibody.Methods:Clinical data of 20 patients diagnosed with encephalitis in the Department of Neurology, First Hospital of Shanxi Medical University from February 2015 to February 2021 were collected and retrospectively analyzed. Patients were divided into 2 groups based on their serum anti LGI1 antibody titers, namely the high titer group (1∶100, 1∶320) and the low titer group (1∶10, 1∶32). The clinical characteristics, laboratory test results, and prognosis of the 2 groups of patients were compared. Relusts The age of the 20 patients with anti LGI1 antibody encephalitis ranged from 27 to 69 (53.5±11.2) years, with a male to female ratio of 1∶1. There were 9 patients in the low titer group and 11 patients in the high titer group. There was no statistically significant difference in the types and quantities of clinical symptoms between the 2 groups. Patients in the high titer group were more prone to abnormal lesions on cranial magnetic resonance imaging (10/11 vs 3/9, P=0.014). There was no statistically significant difference between the 2 groups in the presence or absence of cerebrospinal fluid anti LGI1 antibodies (9/11 vs 4/9, P=0.160). During the follow-up, it was found that 1/20 patient died of pulmonary embolism, 7/20 of patients were able to recover to their predisease state, and 9/20 of patients had residual memory impairment. In the high titer group, 3/11 of patients experienced recurrence, while there was no recurrence in the low titer group. There was no statistically significant difference in the neurological prognosis between the 2 groups at 3 months of discharge and follow-up (the number of patients whose modified Rankin Scale score≤2: 10/10 vs 8/9, P=0.474). Conclusions:Patients with high serum anti LGI1 antibody titers are more likely to develop intracerebral lesions. Higher antibody titers may be associated with a higher risk of disease recurrence. There was no significant correlation between serum antibody titers and neurological outcomes.

The clinical manifestations of anti- N-methyl-daspartate (NMDA) receptor encephalitis and viral encephalitis are similar but the treatments and prognoses are different, so the early differentiation of the two diseases is very important. Early diagnosis is affected by delayed antibody detection and false negative detection, while routine auxiliary tests lack specificity; therefore, they have limited value in identification. The 18F-fulorodeoxyglucose (FDG) marked positron emission computed tomography (PETCT) is highly sensitive to abnormal cerebral metabolism in the early stage of anti-NMDA receptor encephalitis, showing a characteristic metabolic pattern of frontal or temporal lobe increase metabolism and occipital decrease metabolism. The number of patients who underwent 18F FDG PETCT examination for viral encephalitis was small; different kinds of viral encephalitis show different brain metabolism, but there was no characteristic hypometabolism of the occipital lobe. This paper reviews the cerebral metabolic characteristics of 18F-FDG PETCT in anti-NMDA receptor encephalitis and viral encephalitis.
