2.Predictors at nadir of severity on patients with Guillain-Barr? syndrome
Chinese Journal of Neurology 2001;0(02):-
Objective To explore the factors relating to the severity of Guillain-Barr? syndrome (GBS) (i.e. of being the mild form or in need of mechanical ventilation), and to find the predictors in early clinical presentations and laboratory investigations as to guiding the early management of GBS. Methods All 123 cases of patients with GBS admitted to Xuanwu Hospital from 1996-2002 were collected, and divided into two groups based on the international criteria for different severity of GBS. Mildly affected patients (i.e. able to walk unaided during the whole course or the Medical Research Council [MRC] muscle power grading scale≥4 in both lower limbs at nadir) and ventilated patients (i.e. in need of mechanical ventilation) were divided in this study. Characteristics of each group in early clinical presentations and laboratory investigations were analyzed in univariate conditional Logistic model in order to find out the predictors. Results In all 123 patients studied, 32 were having mild GBS; 29 severe GBS (i.e. in need of mechanical ventilation during the course). Men (P=0.047) and patients without bulbar dysfunction (P=0.002) were more likely to become mild GBS. The possibility of being mild form was 3.33∶1 between man and woman, 1∶20.17 between those with and without bulbar dysfunction. Patients with bulbar dysfunction (P

This paper aims to establish a method for the determination of sulfur dioxide in sulfur fumigation Chinese herbs. Sample powder and hydrochloric acid solution were isolated by paraffin layer in order to avoid early reactions, with the generation of sulfur dioxide, headspace with airtight needle was used to transfer sulfur dioxide into gas chromatograph, and detected with thermal conductivity detector. The analytical performance was demonstrated by the analysis of 12 herbs, spiked at four concentration levels. In general, the recoveries ranging from 70% to 110%, with relative standard deviations (RSDs) within 15%, were obtained. The limit of detection (LOD) was below 10 mg x kg(-1). Standard addition can be used for low recovery samples. The method is simple, less time-consuming, specific and sensitive. Methods comparison revealed that gas chromatography is better than traditional titration in terms of method operability, accuracy and specificity, showing good application value.

Objective:To report the clinical manifestations and management of infectious spondylitis following vertebroplasty or kyphoplasty.Methods:Six cases of infectious spondylitis following vertebroplasty or kyphoplasty were analyzed retrospectively which had been treated at Department of Spinal Surgery, Henan Provincial People's Hospital between January 2014 and June 2019. They were 2 males and 4 females, aged from 64 to 81 years. Their visual analogue scale (VAS) scores ranged from 6 to 8 points; their spinal cord function was graded as C in 2 cases and E in 4 according to the American Spinal Cord Injury Association (ASIA) grading. All the patients were treated by sub-total resection of the infected vertebra, long segmental pedicle screw fixation and corresponding antibiotics therapy. The therapeutic efficacy was assessed by the inflammation indexes, imaging examinations and clinical manifestations.Results:The 6 patients were followed up for 12 to 42 months(mean 20.4 months). Their operation time ranged from 295 to 455 min (mean 370.8 min) and blood loss from 760 to 2, 250 mL (mean 1 536.7 mL). There were no such serious complications as dural tear, worsening of neurological symptoms or death. The last follow-up revealed normal body temperature and fine incision healing in all patients. Their inflammatory indexes returned to normal. Imaging examinations at the last follow-up showed no displacement of internal implants, no screw loosening or breakage of screws or rods, good bony fusion at the grafting site, and no inflammatory signals from the infected vertebra. At the last follow-up, their VAS for back pain ranged from 2 to 4 points, the ASIA grading was improved from C to D in 2 patients and maintained E in 4. Eventually, 4 patients recovered independent normal walking but 2 required a walker.Conclusions:Infectious spondylitis following vertebroplasty or kyphoplasty can lead to back pain and neurological dysfunction. Sub-total resection of the infected vertebra, long segmental pedicle screw fixation and corresponding antibiotics therapy can result in fine therapeutic outcomes.

Chinese Journal of Cancer Biotherapy 2000;7(4):243-246
Objective: To study the cellular immune responses and the anti-tumor effects induced by peptides derived from onco-protein HER2/neu. Methods: Two HER2/neu peptides compatible with H-2Kd binding motif as tumor rejection antigens were synthesized. The ability of inducing peptide-specific CTLs and suppressing the tumor growth in BALB/c mice immunized by HER2/neu peptide was analyzed. Results: HER2/neu peptides could promote the proliferation of BALB/c lymphocytes both in vitro and in vivo. HER2/neu peptide-specific CTLs could be induced from peptide-immu-nized BALB/c mice, which showed specifically killing effects on HER2/neu positive SP2/OHER2 cells but not on HER2/neu negative SP2/O cells. Moreover, the growth of SP2/OHER2 tumor were significantly suppressed in BALB/c mice immunized with HER2/neu peptides. Conclusion: These results suggested that it was feasible to use MHC-I epitopes derived from tumor-specific antigens as vaccines for cancer immunotherapy.

Background Primary open angle glaucoma (POAG) is a major blindness-causing disease,characterized by elevated intraocular pressure due to an insufficient outflow of aqueous humor. The trabecular meshwork lining the aqueous outflow pathway modulates the aqueous outflow facility. To study the biological characteristics of the trabecular meshwork cells has important significance. Objective This study was to culture the trabecular cells from primary open-angle glaucomatous eye (POAG) and study the biologic characteristics of passaged cells. Methods The deep scleral tissue with trabecular meshwork was obtained during the trabeculectomy from 8 eyes with POAG. The trabecular cells were primarily cultured and passaged in vitro. The generation 3 cells were identified by immunochemistry with the laminin (LM), fibronectin (FN) and neuron specific endolase (NSE)monoclonal antibodies. The ultrastructure was examined to observe the biological characteristics of the cells under the transmission electronic microscope. The experimental results were compared among POAG group, normal control group and blank control group. Results The primarily cultured POAG trabecular cells migrated from the edge of tissue mass about 10 days. The cells of generation 3 presented the logarithmic phase in the first 4 days and fused in the 7th day. FN,LM and NSE were positively expressed in the generated cells in POAG group and normal control group rather than blank control group. The MOD values of the generation 3 cells for FN in POAG group and normal control group were 0. 35 ± 0.06 and 0. 26 ± 0. 01, and those for LM were 0. 34 ± 0. 03 and 0. 25 ± 0. 02 respectively, showing statistically significant difference between these two groups ( FN: t = 14. 446, P<0.001; LM: t = 9. 346, P<0. 001 ). The microvilli, cytolysosome and phagocytic vesicle were obviously decreased in the trabcular cells of POAG group compared with normal control group under the transmission electron microscope. Conclusion The trabecular meshwork cells from POAG can be successfully cultured and passaged in vitro. It provides a cytology basis for further glaucoma research.
