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

In the paper, we used the culture medium for L-form of gonococcus and dryg sensitivity test to iso late 18 strains of L-form of gonococcus from 84 patients susoected of gonorrhea in clinical practice. Conventional culture medium for gonocuccus were used as control. The result showed that the culture of L-form of gonococcus increased foe rate of detection of gonococcus and decreased under diagnosis. It is helpful in guiding the treatment.

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.

The ancient literature on Taiyuan (LU 9) was collected to summarize the application laws of this acupoint. One thousand TCM ancient works collected in Chinese Medical Dictionary (fourth edition) were retrieved. The literature on the indications of Taiyuan (LU 9), the indications of Taiyuan (LU 9) combined prescriptions, the laws of acupoints combination and the techniques of acupuncture and moxibustion was collected systematically and the database was set up. It is found that there are 333 provisions in compliance with the inclusive standard of Taiyuan (LU 9), 306 provisions for the treatment of disorders and 66 relevant ancient works. There are 119 provisions relevant with the indication of single Taiyuan (LU 9) , 187 provisions for the applications of the combined prescriptions and 143 acupoints for the combined acupoints. Taiyuan (LU 9) and the combined prescriptions are applied to every department in clinic, especially for the disorders of TCM internal medicine department. The combined acupoints are distributed among the fourteen meridians and extra points and had been used totally for 1142 times. Of these points, there are 9 acupoints from the lung meridian of hand-taiyin and 25 acupoints from the bladder meridian of foot-taiyang, with the highest use frequency, 195 times and 141 times respectively, accounting for 17.08% and 12.35% of the total frequency. The common pairs of combination are Taiyuan (LU 9) and Yuji (LU 10), Taiyuan (LU 9) and Lieque (LU 7) and Taiyuan (LU 9) and Taibai (SP 3). The common dose of moxibustion at the acupoint is 3 cones. The depth of insertion is 0.2 cun and the acupuncture time is two breathes.

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.

Clinical medicine professional degree education focuses on cultivating students' ability to engage in clinical practice, but the aim of medical postgraduate education program is to cultivate high-leveled clinical and research personnel. In the light of the problems that professional degree postgraduates majoring in obstetrics and gynecology are faced with such as unreasonable energy distribution in scientific research, the weak foundation of scientific research, the emergence of new trend of obstetrical and gynecological dis-eases, we have explored how to improve obstetrics and gynecology professional students' scientific research ability from several aspects such as the guidance of mentors, transferring learning and thinking and strength-ening the communication between various disciplines, to adapt to the requirements of the scientific develop-ment of modern obstetrics and gynecology.

Objective To assess prevalence and risk factors of illness within the past 2 weeks among rural residents in Menglian,under the background of essential public health service implemented generally. Methods In February 2012, the questionnaire method was employed to investigate the two-week morbidity in 2011 rural residents sampled by multistage stratified random sampling from Menglian population. Results The prevalence, that of illness within two-week among 2011 rural residents in Menglian, was 97.5‰ (95%CI 84.5‰-110.5‰) . It was lower than that of the rural region IV in China (149.6‰, <0.05) .Its age trend was the same as that of the rural region IV in China,the prevalence in 0-14 years old children,however,was higher than the counterpart in the rural region IV in China. The diseases, which two-week morbidity ranked the top five, were acute upper respiratory infection, acute gastroenteritis, hyperostosis, acute tracheobronchitis and rheumatoid arthritis. The results of multilevel logistic regression model fitted by group-level explanatory variable mountainous area, individual-level random slopes variable gender and other individual background variables indicated that there were across-level interactions between mountainous area and gender ( <0.05), the family income lower than RMB 15000 (odds ration 3.2378, 95%CI 1.9014-5.5130) and age (odds ration 1.0163, 95%CI 1.0002-1.0327) had a positive effect to two-week morbidity, and contrasting to unmarried, married had a negative effect to two-week morbidity (odds ratio 0.4727, 95%CI 0.2534-0.8819) . Conclusions Comparing with that of the rural region IV in China before implementing essential public health service, the two-week morbidity in Menglian was lower. For further elevating the health level of population, the strategies, such as intensifying material and child hygiene in the mountain area, improving sanitary conditions of low income family, and updating health consciousness in single population,would be implemented.

Objective To investigate the relationship between alexithymia and event-related potential P300 in patients with somatoform disorders.Methods Forty-two patients aged 18 to 65 years fulfilling ICD-10 diagnosis criteria for somatoform disorders were recruited as experiment group.Forty normal healthy persons were selected as control group.The Toronto alexthymia scale-20 (TAS-20) was employed to investigate the alexithymia of the subjects.P300 potentials was employed to investigate the cognitive ability of the subjects.A comparison was made between the patients and the healthy subjects.Results The latencies of N1,P2,N2 and P3 were significantly longer in patients with somatoform disorder than those in the normal controls (P ＜ 0.05 or 0.01),the amplitudes of N2 and P3 were significantly lower in the patients (P ＜ 0.05 or 0.01).The three factors scores and the total score of TAS-20 test in patients with somatoform disorder were significantly lower than those in the normal controls (P ＜ 0.05 or 0.01).There was significant correlation between the latency and the three factors scores and the total score of TAS-20 as well as between the amplitude of P300 and the three factors scores and the total score of TAS-20:the latencies of N1,P2,N2 and P3 recorded at Pz was positively correlated with the factors scores (r =0.32 ～ 0.48,P ＜ 0.05 or 0.01),and the amplitudes of N1,P2,N2 and P3 recorded at Pz was negatively correlated with theTAS-20 scores (r=-0.31 ～-0.51,P＜0.05 or0.01).Conclusions There existed significant correlation between the alexithymia and cognitive impairment in patients with somatoform disorders.Both alexithymia and event-related potential P300 can be used as a clinical evaluation index for patients with somatoform disorder.
