ObjectiveTo explore the role of ssomatosensory evoked potential (SEP) in evaluating and predicting the lower limb motor function of patients with acute cerebral infarction.Methods19 patients (13 male, 6 female) with acute cerebral infarction diagnosed according to the standard of Chinese Classifications of the Cerebral Vascular Disease were chosen as the case group and 18 patients (11 male, 7 female) with non-nerve system injury were taken as the control group. All patients of two groups were received SEP test within 7 days after onset and latency and amplitude values of SEP of two groups were compared. To the case group, SEP was tested again at 30th day after admission, the Fugl-Meyer assessment (FMA) was also carried out at same times of two SEP tests, and the correlation of SEP and FMA scores was analyzed.ResultsThe difference of latency and amplitude value of SEP test between the case group and control group was significantly (P<0.01). The latency value of SEP in lower limb was correlated with FMA scores (P<0.01). But the amplitude value was no difference between the onset and 30th day after admission in the case group.ConclusionSEP is sensitive in the acute stage of stroke. SEP has significant value for predicting the prognosis of patients with acute cerebral infarction and correlates with the clinical FMA scores. The value of amplitude is not sensitive.

Objective To investigate the adverse effects of taurine on rabbit corneal endothelial cells. Methods Six rabbits (12 eyes) were selected, and 6 histologic sections were prepared from each of the eyes. Rabbit corneal endothelial cells were cultured by explant culture method. Cells were innoculated on a 12-well tissue culture plate, 2%, 4%, 6%, 8% and 10% taurine solutions were added respectively (cells from the right and left eyes of the same rabbit were added the same concentration of taurine solution), and blank control was established. The growth of corneal endothelial cells was observed by inverted microscopy, and cell morphology on the 1st, 2nd, 4th, 6th and 8th day of culture was observed with Wright staining. Results Corneal endothelial cells cultured with 2%, 4% and 6% taurine solutions and those of blank control formed endothelial cell layers after culture for one week, and the cells exhibited hexagonal or round-like morphology. Corneal endothelial cells cultured with 8% taurine solution appeared to be undergrowth with small cell body on the 4th day, and cell death occurred on the 8th day. Corneal endothelial cells cultured with 10% taurine solution turned out to be undergrowth with small cell body on the 2nd day, and cell death had occurred. The same growth velocity and cell morphology were observed in the corneal endothelial cells from the right and left eyes of the same rabbit. Conclusion Taurine with concentration between 2% and 6% has no adverse effects on the growth of rabbit corneal endothelial cells.

Objective To study the immunophenotypic features of NK/T cell lymphoma in children and its association with Epstein-Barr virus (EBV) infection. Methods Five cases of children′s NK/T cell lymphoma were studied. CD45RO, CD3?, CD56, CD20, TIA-1 and granzyme B were detected by immunohistochemistry staining for investigating immunophenotype. The expression of EBV-latent membrane protein (LMP-1) were detected by immunohistochemistry. EBV-encoded RNA (EBER1/2) were detected by in situ hybridization (ISH). Results CD45RO, CD3?, TIA-1 and granzyme B were positive in 5 cases, CD56 was positive in 2 cases, while CD20 negative in 5 cases.EBER1/2 positive in 4 cases and LMP-1 positive in 3 cases.Conclusions NK/T cell lymphoma in children is strong associated with EBV infection,and EBV infection may play an important role in the pathogenesis of children NK/T cell lymphoma.

In temporomandibular disorders (TMD), pain takes place when neuropeptides stimulate synovial tissue to produce several cytokines such as interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α, which activate neurons and glia of synovial membrane at the bilaminar regions of temporomandibular joint (TMJ). It has been reported that, after neurogenic differentiation, the synovial mesenchymal stem cells (SMSCs), deriving from TMJ, possess the same cytological features as the neuronal cells. This study examined the ability of substance P (SP) and calcitonin gene-related peptide (CGRP) to stimulate SMSCs and neurogenic SMSCs secreting inflammatory cytokines during TMD, evaluated the mutual effects of inflammatory cytokines and neuropeptides and tested the analgesic effect of hyaluronic acid (HA). The levels of IL-1β, IL-6 and TNF-α in SMSCs and neurogenic SMSCs in the presence of neuropeptides were measured by ELISA. SP and CGRP produced by SMSCs and neurogenic SMSCs were determined by RT-PCR and Western blotting. The results showed that the expression of SP and CGRP was significantly enhanced in the neurogenic SMSCs in response to IL-1β, IL-6 and TNF-α, and the effect was remarkably inhibited by HA. IL-1β, IL-6 and TNF-α, in return, could be enhanced in the neurogenic SMSCs upon stimulation by SP and CGRP. Neuropeptides and inflammatory cytokines might work mutually on the TMD pain. The HA-mediated analgesic effect may be implicated in the inhibition of SP and CGRP expression in neurogenic SMSCs.

This study aims to assess if adverse drug reactions (ADRs) to parenterally administered salvianolate are allergic in origin. Hospital information system (HIS) data from 20 hospitals in China were used to carry out a retrospective nested case control design study. Included were patients who received dexamethasone for suspected allergic reactions after receiving parenterally administered salvianolate. These were compared with non-allergic reaction people. Single factor logistic regression and multiple factor logistic regression were used to analyze data. Condition on admission, allergic history, dosage, disease status and drug combinations were taken into account in cases of suspected allergic reactions. After analysis in two subgroups we found that the condition on admission had a significant effect, P values was < 0.000 1 on suspected cases of allergic reactions in the first subgroup analysis. For the second subgroup analysis, we found condition on solvents had a significant effects, P values was 0.005 1 on suspected cases of allergic reactions. We also found that using other four injections at the same time as parenterally administered salvianolate could be risky factors in suspected cases of allergic reactions. For the second subgroup analysis combining using three injections could increase risks. However, further research for verification is required. This study can provide guidance for safe clinical practice in using parenterally administered salvianolate.

To investigate the clinical course and management of congenital vaginal atresia.This retrospective analysis included patients with congenital vaginal atresia treated from March 2004 to August 2014 at the Obstetrics and Gynecology Hospital of Fudan University.Thirty-nine patients were included in this study.Their average age was 16.87±2.2 years when they came to our hospital.Totally,51％ of the patients had isolated congenital vaginal atresia with a normal cervix,whereas the others had either cervical atresia or imperforate hymen.The primary presenting signs and symptoms included primary amenorrhea (71.8％),periodic abdominalgia (41.0％),abdominal pain (36.0％),dyspareunia (10.3％),menstrual disorders (5.1％),and pelvic mass (5.1％).Ultrasound and magnetic resonance imaging (MRI) were effective inspection methods for the screening of urogenital tract-associated anomalies.Vaginoplasty mainly included simple vagina reconstruction with insertion of a mold (n=22) and split-thickness skin grafting (n=4).In 64％ of surgical patients,normal menstrual bleeding was achieved.Four of the patients subsequently became pregnant and delivered at term.Primary amenorrhea,periodic abdominalgia and abdominal pain are the main reasons for the post pubertal patients to visit doctors.Surgical methods can successfully provide these patients an opportunity for subsequent conservative management,can result in normal menstrual bleeding,resolve cyclic pelvic pain,and provide some potential for fertility.

Ergosterol is the important component of the fungal membrane, and having stable structure. This makes it a suitable indicator for growth of fungi. In the paper, isolation and determination techniques of ergosterol as the indicator of the fungal biomass were reviewed. The methods of extracting ergosterol include traditional saponification and refluxing, rapid physical disruption, rapid ultrasonication, supercritical fluid extraction and so on. The ergosterol determination methods are high performance liquid chromatography, gas chromatography-mass spectrometry, liquid chromatography-mass spectrometry, and thin-layer chromatography, et al. The application of these techniques was also introduced. Finally, the paper prospected the feasibility of applying the ergosterol as the indicator of fungal biomass in composting.
