Neurological paroxysmal disease is a large group of clinical syndrome with a characteristic of sudden, recurrent, self-limiting. Clinically, routine biochemical or imaging examinations are usually with no significant abnormalities in the interictal period. However, magnetoencephalography (MEG), as an important electrophysiological tool in studying brain magnetic signals and monitoring brain electric activity, has highly temporal and spatial resolution for its noninvasive measurement of human brain with superconducting quantum interference. Therefore, it has been gradually used in researching for functional activities and mechanisms of the neuropsychiatric disorders and the advanced brain activity. There mainly reviewed the application and studies of MEG in epilepsy, paroxysmal kinesigenic dyskinesias and migraine.

OBJECTIVETo explore the effects of integrative medicine (IM) rehabilitation protocolon motor function, activity of daily living, and quality of life (QOL) in hemiplegia patients after stroke.

METHODSTotally 120 patients with post-stroke hemiplegia were allocated to four groups using sealed envalope drawing, i.e., the rehabilitation group, the Chinese medical treatment group, the acupuncture group, and the comprehensive rehabilitation group, 30 cases in each group. Based on routine rehabilitative training, patients in the Chinese medical treatment group, the acupuncture group, and the compre-hensive rehabilitation group received standardized treatment based on syndrome typing, Shi's Consciousness-Restoring Resuscitation acupuncture, Chinese herbs + acupuncture comprehensive rehabilitatino protocol, respectively. The treatmet cycle consisted of 4 weeks with 24-week follow-ups. Fugl-Meyer motor assessment (FMA), Modified Barthel Index (MBI), and Stroke-Specific Quality of Life Scale(SS-QQL), and safety assessment were taken as main effect indices before treatment, at week 4 of treatment, at week 12 and 24 of follow-ups, respectively.

RESULTSThere was no statistical difference in FMA score, MBI score, SS-QOL score among the four groups before treatment (P > 0.05). These scores were significantly improved in the four groups at week 4 of treatment, week 12 and 24 of follow-ups, respectively (P < 0.05). Besides, FMA score and SS-QOL score were significantly improved in the comprehensive rehabilitation group at each corresponding time point, as compared with other treatment groups (P < 0.05).

CONCLUSIONSThe comprehensive protocol could significantly improve motor function, activity of daily living in hemiplegia patients after stroke, and further improve their QOL. Its effect was better than other single treatment.

Hereditary spastic paraplegia (HSP) is a group of significantly clinically and genetically heterogeneous neurodegenerative disorders, which are predominantly characterized by progressive lower limbs weakness and spasticity inducing gait abnormalities or disorders. In practice, based on the modes of inheritance, it can be divided into autosomal dominant, autosomal recessive, X-linked and mitochondrial maternal inheritance. According to whether the clinical manifestations complicated or not, HSP can be divided into pure and complex form. To date, mutations in 78 distinct loci and 59 mutated gene products have been identified or reported in patients with HSP; among them 20 distinct loci and 13 mutated gene products have been found in autosomal dominant spastic paraplegia. This is a review about the genetic characteristics and research progress of autosomal dominant HSP.

Hereditary spastic paraplegia (HSP) is a group of significantly clinically and genetically heterogeneous neurodegenerative disorders, which are predominantly characterized by progressive lower limbs weakness and spasticity, and spastic paraplegia type 4 (SPG4) is the most common type among them. So far, mutations in 78 distinct loci and 59 mutated genes have been identified in patients with HSP. The protein spastin coded by the SPAST gene plays a critical role in regulating length, number and activity of microtubules, as well as the occurrence and development of various organelles. It is generally believed that the mutated spastin leads to partial or total loss of the function, which is the main pathogenetic mechanism. While recent studies have also suggested that there may exist acquired neurotoxic effects of mutant proteins by the two isoforms (M1, M87) coded by the SPAST gene, which is also one of the critical mechanisms. In this paper, the pathogenesis of SPG4 was reviewed.

57 rubella virus strains were isolated using Vero cell line or Vero/SLAM cell line from patients' throat swabs during rubella outbreaks and sporadics in 10 provinces of China from 2003 to 2007. Fragments of 1107 nucleotides of E1 genes of the isolates were amplified by RT-PCR, the PCR products were directly sequenced and analyzed. The phylogenetic analysis based on 739 nucleotides showed that out of 57 Chinese rubella virus strains, 55 belong to a distinguish branch of 1E genotype when comparing with 1E genotype rubella strains from other countries, and the other 2 Chinese rubella virus strains belong to 2B genotype. Most of the nucleotide mutations of 57 rubella viruses were silent mutations, and the amino acid sequences were highly conserved. Except one amino acid change (Thr212 --> Ser212) in two rubella viruses at the hemagglutination inhibition and neutralization epitopes, there had no change found at the important antigenic epitope sites of the other rubella viruses. 1E genotype rubella viruses isolated from 10 provinces of China from 2003 to 2007, and two imported 2B genotype rubella viruses from Vietnam suggested that 1E genotype was the predominant genotype in this period of time. The rubella virus genotypes circulated during 2003 to 2007 were different from that circulating during 1979 to 1984 and 1999 to 2002, the rubella prevailed in recent years was mainly caused by 1E genotype rubella viruses with multi-transmission routes.

OBJECTIVELyme disease and Human granulocytic anaplasmosis are tick-borne diseases caused by Borrelia burgdorferi and Anaplasma phagocytophilum respectively. We have investigated infection and co-infection of the two diseases in the population of forest areas of eight provinces in China by measuring seroprevalence of antibodies against B. burgdorferi and A. phagocytophilum.

METHODSForest areas in 8 provinces were chosen for investigation using whole sampling and questionnaire survey methods. 3 669 serum samples from people in the forest areas were tested for the presence of antibodies by indirect immunofluorescent assay (IFA).

RESULTSSeroprevalence against B. burgdorferi was 3% to 15% and against A. phagocytophilum was 2% to 18% in the study sites in the 8 provinces in China. We also found co-infection of B. burgdorferi and A. phagocytophilum in 7 of the 8 provinces (the exception being the Miyun area in Beijing). The seroprevalence for both B. burgdorferi and A. phagocytophilum was significantly higher among people exposed to ticks than among people who were not exposed to ticks.

CONCLUSIONWe conclude that both pathogens are endemic in the forest areas in the eight provinces, but the prevalence of B. burgdorferi and A. phagocytophilum differs between the provinces.

OBJECTIVEThe aim of this study is to analyse the efficacy and toxicity of CEOP regimen in the treatment of non-Hodgkin's lymphoma (NHL).

METHODSFrom January 1995 to December 2000, 121 patients with NHL were treated by CEOP regimen with or without radiotherapy for the involved field. The clinical characteristics, response, toxicity and long-term survival results were analysed retrospectively.

RESULTSOf these 121 patients, 83 (68.6%) had B-cell NHL and 38(31.4%) peripheral T or NK-cell NHL; 55. 4% (67/121) had early disease (stage I or II), and 89.3% (108/121) had IPI score 0-2. The median age was 53 years (range: 7-79 yr). All patients were treated by CEOP regimen (totally, 471 cycles) with or without radiotherapy. The overall response (OR) rate in this series was 90.9% (110/121) with a complete remission (CR) rate of 71.9% (87/121); whereas the response rate of chemotherapy alone was 88.4% (107/121) with a CR rate of 67.8% (82/121). Major toxicity consisted of grade III-IV myelosuppression (11.9%), neutropenia (1.9%) and thrombocytopenia and anemia (1.1%). Alopecia was observed in 46.3%. However, cardiotoxicity was mild and reversible. Median follow-up duration in this series was 63 months (range: 2-116 months). The overall 1-, 3- and 5-year survival rate was 84.8%, 62.7% and 55.9%, respectively, with a median survival time of 85 months (2-118 months).

CONCLUSIONOur data show that CEOP regimen combined with or without radiotherapy for the involved field is effective and well tolerated by the patients with non-Hodgkin's lymphoma.

Aim To investigate the effect of Medi- coscab Tincture could increase the healing rate of burn coscab Tincture on the wound repair of deep partial thickness burn in rats and its possible mechanism. Methods SD100 rats were used to make a rat model of deep partial thickness burn. The rats were randomly divided into five groups; normal, model control, positive control, Medicoscab Tincture high-dose, and Medicoscab Tincture low-dose. The dosing group was changed daily for 14 consecutive days. The healing rate and water content of wound were measured at 3 d, 7 d and 14 d after burn. The activities of superoxide dismutase (SOD) and catalase (CAT) and the content of malondialdehyde ( MDA) were determined by bio-chemical analysis. Serum levels of tumor necrosis fac- tor-a (TNF-a), interleukin-1 (3 (IL-1(3) and interleu- kin-6 (IL-6) in rats were determined. Results Medi- wound and decrease the water content of burn wound tissue in rats ( P < 0. 05 ). The activity of SOD significantly increased, the content of MDA decreased (P < 0. 05), and the contents of TNF-a, IL-1 (3 and IL-6 in serum of burned rats decreased ( P < 0. 05, P < 0.01). Conclusions Medicoscab Tincture can improve the wound healing rate, reduce the wound water content, increase SOD activity, reduce the content of MDA in the wound, and reduce the serum levels of inflammatory factors TNF-a, IL-1 (3 and IL-6. Therefore, Medicoscab Tincture has a protective effect on deep partial thickness burn in rats.

This study was purposed to investigate the expression of latent membrane protein 1 (LMP-1) and CD68 in Hodgkin's lymphoma (HL) patients with EB virus infection and to analyze the relation of LMP-1 expression and CD68(+) tumor-associated macrophage count with clinical features and prognosis of HL patients. The expression of LMP1 and count of CD68(+) TAM were detected by immunohistochemical staining in tissue specimens of 72 HL patients; their correlation with clinical features and prognosis of HL patients was analyzed by using statistical method. The results showed that among tissue specimens of 72 HL patients, the positive rate of LMP-1 expression was 18.1% (13/72), the CD68(+) TAM count was more higher in LMP-1 positive expression [250 of CD68(+) TAM/high power field (hpf) is used as demarcation point] (P = 0.003). The statistical analysis showed that the LMP-1 positive expression was more observed in mixed type HL patients (P = 0.000); the positive rate of LMP-1 expression was much high in HL patients with albumin <40 g/L and age ≥ 45 years (P < 0.05). There was no relation of LMP-1 expression and CD68(+) TAM count with the short term therapeutic efficacy of HL patients, but the overall survival time of LMP-1 positive patients among patients followed-up for ≥ 5 years was short (P < 0.05). Moveover, no correlation of CD68(+) TAM count with the overall survival time of HL patients was found. It is concluded that the high count of CD68(+) TAM is more observed in LMP-1 positive expression of HL tissue, the LMP-1 expression states relates both with the pathological types, age and albumin level of patient with HL. The HL patients with LMP-1 positive expression have poor prognosis, suggesting that LMP-1 may be a new prognostic marker for HL patients.

OBJECTIVES: To develop a new Chinese medicine (CM)-based drug and to evaluate its safety and effect for suppressing acute respiratory distress syndrome (ARDS) in COVID-19 patients. METHODS: A putative ARDS-suppressing drug Keguan-1 was first developed and then evaluated by a randomized, controlled two-arm trial. The two arms of the trial consist of a control therapy (alpha interferon inhalation, 50 µg twice daily; and lopinavir/ritonavir, 400 and 100 mg twice daily, respectively) and a testing therapy (control therapy plus Keguan-1 19.4 g twice daily) by random number table at 1:1 ratio with 24 cases each group. After 2-week treatment, adverse events, time to fever resolution, ARDS development, and lung injury on newly diagnosed COVID-19 patients were assessed. RESULTS: An analysis of the data from the first 30 participants showed that the control arm and the testing arm did not exhibit any significant differences in terms of adverse events. Based on this result, the study was expanded to include a total of 48 participants (24 cases each arm). The results show that compared with the control arm, the testing arm exhibited a significant improvement in time to fever resolution (P=0.035), and a significant reduction in the development of ARDS (P=0.048). CONCLUSIONS Keguan-1-based integrative therapy was safe and superior to the standard therapy in suppressing the development of ARDS in COVID-19 patients.
