In control group, there obvious edema of cells, capillaries and sheaths in the marginal zone of cortex necrosis,and reduction of organelles of neuron. As well. In No. 3 and No. 4 medicated groups, the limits of cell membranes were clear, the structure was integral, the chondriosomes were rich and even in size,the medullated fibers were morphologically normal.And in No.1 and No.2 medicated groups the changes were between the twoCONCLUSION:① The scoring of dysneuria in rats was decreased after the blood-activating and stasis-resolving medicine was given,and it was lower in rats that were given a longer period of medication,indicating that the improved extent for dysneuria is related to prolonged medication.②The nitric oxide concentration of cerebral tissue in rats that recevied the blood-activating and stasis-resolving medicine was decreased, and the nitric oxide concentration of serum in the rats was increased,indicating that the blood-activating and stasis-resolving medicine can reverse the anomalies of nitric concentration in different tissues after ischemic reperfusion so as to reduce cerebralinjury.③ The levels of C3 and C4 of cerebral tissue and serum in rats that received the blood-activating andstasis-resolving medicine were obviously decreased,indicating that the medicine may reduce the cerebral injury through triggering complement system;and the CRP was also get decreased,further suggesting that the medicine can inhibiting infective reaction.④ The longer the period of medication,the milder the cerebral injury, and the dose of 2.5 g/L was better in effect.

BACKGROUND: It has been known that re-recovery of blood flow after cerebral ischema may aggravate brain injury. It has been verified in some researches that the components for activating blood circulation and removing stasis in Chinese herbs can resist cerebral ischemic reperfusion injury.OBJECTIVE: To observe 4 most basic Chinese herbs for activating blood circulation and resolving stasis [honghua (Flos Carthami), taoren (Semen Persicase), chuanxiong (Rhizoma ligustici Chuanxiong) and chishao (Radix Paeoniae Rubra)] as the exertive factors on their influences on immune index changes in IgG, C-reactive protein (CRP) and complements of serum and homogenate in brain tissue so as to verify their graded and time effects.DESIGN: Randomized control experiment and single blind method.SETTING: Guangzhou Red Cross Hospital and Department of Neurology of the Fourth Hospital Affiliated to Jina University.MATERIALS: The experiment was performed from January 2001 to Decemb er 2002 in Experimental Room of Traumatic Institute of Guangzhou Red Cross Hospital. Totally 138 SD female adult rats were employed, mass weighted varied from 280 to 300 g, provided from Experimental Animal Center of Guangzhou University of Chinese Medicine. Honghua (Flos Carthami), taoren (Semen Persicase), chuanxiong (Rhizoma ligustici Chuanxiong)and chishao (Radix Paeoniae Rubra)] were the concentrated granules individually. At the ratio of 1:1:1:2, they were prepared into 2.5 g/mL raw herbal decoction (huoxue huayu tang).INTERVENTIONS: Thread embolic method was used to prepare cerebral medium sized artery obstruction model in rats (reperfusion for 24 hours after cerebral medium sized artery obstruction for 2 hours). Totally 138 rats were randomized into 6 groups, 23 rats in each. Sham operation group: ligature was done in each vessel without blocking medium sized artery of cerebrum.First perfusion group: 30 minutes before operation, gastric peffusion was done with 2 g/kg huoxue huayu tang. Second peffusion group: 30 minutes before operation, gastric perfusion was done with 2.5 g/kg huoxue huayu tang. Third perfusion group: before operation, gastric perfusion was done with 2 g/kg huoxue huayu tang continuously for 7 days. Fourth perfusion group: before operation, gastric perfusion was done with 2.5 g/kg huoxue huayu tang continuously for 7 days. In the control, physiological saline of all of the groups, when rats woke up, after 24 hours reperfusion and 2 hours ischemia, neural functional deficits were evaluated (5-score system, 0-1:After 24 hours reperfusion, 10 rats were randomized from each group for determination of the contents of CRP in homogenate and serum, complehours reperfusion, 10 rats were randomized from each group. After anesthetized, they were sacrificed rapidly to collect brains. Dried over heat in oven at 110℃ till constant weight, the water content of brain tissue was domized from each group to observe ultrastructure of brain tissue under transmission electron microscope (TEM) of rats in each group.and homogenate, complement C3 and C4 as well as serum IgG in rats of of severe neural functional deficits after 24 hours ischemic reperfusion in rats of each peffusion group was lower remarkably than the control (P ＜ 0.01),in which, that in fourth peffusion group was lower than second group (13%,group and each perfusion group was lower than the control (P ＜ 0.05), in which, that in third peffusion group was lower than first group (P ＜ 0.01).ment C3: That in sham operation group and each perfusion group was lower sham operation group and each perfusion group was lower than the control ( P ＜ 0.01), in which, that in third perfusion group was lower than first group (P ＜ 0.01); That in fourth perfusion group was lower than second and group and each perfusion group was lower than the control (P ＜ 0.01), in which, that in fourth perfusion group was lower than second group(P ＜ 0.05).each perfusion group was lower than the control (t=5.626-17.929, P ＜ 0.01),in which, that in third perfusion group was lower than first group (P ＜ 0.01),complement C3 in brain homogenate: That in sham operation group and each perfusion group was lower than the control (P ＜ 0.05-0.01), in which, third perfusion group was lower than first group (P ＜ 0.01), that in fourth group brain homogenate: That in sham operation group and each perfusion group was lower than the control ( P＜ 0.05-0.01), in which, that in third perfusion group was lower than first group (P ＜ 0.01), that in fourth group was lower tissue: The inflammatory reaction in the control was obvious. Brain edema and pathological damage in perfusion groups were milder than the control.Ulztrastructure was normal in sham operation group. The edema was obvious in cells, capillaries and myelin sheath in cortical necrosis margin area and neuronal cell organs were decreased in the control. In third and fourth peffusion groups, cellular membrane was clear in boundary line,integrative in structure, rich in mitochondria and even in size and the morphology of medullated fibers was normal. The situation of first and second perfusion was between two of them.deficits in the evaluation of rats and the score with long medication was lower, suggesting that long medication can even better improve neural funcplement C3 and C4 in brain bomogenate and serum and decreases serum IgG content, explaining that the medicine alleviates brain tissue injury by startup complement system. The remarkable decrease of C-reactive protein further suggests the inhibition of such medicine on inflammatory reaction.jury is, and the better result is achieved at dosage of 2.5 g/L.

Four weeks after SD diabetic rats were induced by streptozotocin,skin thickness was obviously reduced with obscure multilayer epithelium features.Moreover,the thickness of epidermic layers in diabetic rat skin was significantly thinner than that ofnornlal rat skin at the eighth week[(0.016±0.006 vs 0.041±0.007)mm,P<0.01].The percentage of G2/M phase cells in epidermic layers of diabetic group was significantly lower than that in the normal group.At the twelfth week,skin microangiopathy was easily detected in the diabetic group.The blood levels of advanced glycation end products(AGEs)and malonialdehyde were significantly increased and glutathione decreased in diabetic rats compared with control rats(aU P<0.01),along with the increased contents of local glucose and AGEs in the skin of diabetic rats.These results suggest that the local accumulation of glucose and AGEs seems to be one of the important mechanisms in the pathogenesis of diabetic skin lesions.

Objective To study the significance of human rhinovirus C as a pathogen and the clini-cal features of human rhinovirus C infection in pediatric intensive care unit. Methods From November 2010 to April 2012,570 nasopharyngeal aspirates specimens were collected from children who were admitted to the pediatric intensive care unit with respiratory infections. Nest reverse transcription-polymerase chain reactions were applied to detect the human rhinovirus C. The other common respiratory viruses were detected by multi-plex polymerase chain reaction. The clinical data were collected. Results One hundred and seventy human rhinovirus positive samples ( 29. 8%) were detected in 570 nasopharyngeal aspirates specimens. The VP2/VP4 and 5′UTR region of the human rhinovirus genome was amplified from 170 human rhinovirus positive samples with 80. 6%(136/170) success. While 20. 0%(34/170) samples in total were unclassified to spe-cies. There were 85 single infected samples including 52 of type A,7 of type B,26 of type C. The nucleotide homology was 74. 0% to 99. 2% and the nucleotide variations was 3. 4% to 32. 3% in stains of human rhino-virus C. The late fall and early winter were the epidemic seasons of human rhinovirus C infection. Cough,fe-ver, polypnea and wheezing were the common symptoms. Conclusion Human rhinovirus C is the major cause of infectious disease in pediatric critical illnesses. Human rhinovirus C infections often cause cough, fever,polypnea and wheezing.

Juvenile myopia has become a serious public health problem in China, presenting rapidly increasing incidence and younger onset age.Refractive eye development is controlled by both genetic and environmental factors.In recent years, near work among environmental factors has become a hotspot in myopia risk factors research.However, the association between near work and myopia still remains controversial.In this article, the epidemiological studies on the relationship between near work content, total time spent on near work, intensity of near work and myopia, and its possible mechanisms (including near-work-induced transient myopia, accommodative lag and scleral hypoxia) were summarized, so as to provide reference for myopia epidemiology and etiology.

OBJECTIVETo detect putative suppressor loci involved in tumor progressing or metastases.

METHODSThirty microsatellite marker primers were employed to amply the corresponding loci of the genome DNA from 83 patients with sporadic colorectal cancer. The PCR products were electrophoresed on a 377 PRISM sequencer and the fluorescent signals were analyzed by Genotyper and Genescan software.

RESULTSThe data were obtained from 24 loci, with an average LOH frequency of 15.16%. The LOH at D2S206 and D2S364 was more frequent than 30%, and was less than 20% at the rest loci. Significant difference was observed between the percentage of LOH and tumor staging or differentiation at D2S142 (2q24.1), D2S126 (2q35), D2S2211 (2p24.2), D2S305 (2p23.3). Occarrence of deletion at the later two loci was correlative.

CONCLUSIONSFrequent LOH was not observed at the loci around known mismatch repair genes on chr. 2. The region between D2S305 (2p23.3) and D2S2211 (2p24.2) deleted holistically, and was correlated to the stage and differentiation of tumor attended by D2S142 (2q24.1) and D2S126 (2q35) on 2q. It is suggested that unknown genes associated with tumor progressing or metastases reside in the two loci on 2q or the region on 2p.

Objective To report a case of disseminated cryptococcosis with cutaneous manifestations and osteomyelitis. Methods and Results A 33 year old female was admitted due to multiple nodules and ulcers on the upper arms, shoulders, buttocks and thighs for one year. The patient was pregnant when admitted, and gave birth to a premature baby during her illness. The nodules increased half a month after delivery, which was suspected to be hematogenously disseminated pulmonary tuberculosis and was given anti tuberculous therapy for three months but failed. Physical examination showed there were 39 nodules or ulcers on the face, gum, trunk, buttocks and extre mities. The bone structure of the left tibia and fibula destroyed and a sinus developed on the left fibula. Microbiologic examination showed that lots of spores were seen in the smear of pus and necrotic tissues, which produced yeast like colonies in culture with positive urease and caffeic acid test. Cryptococcus neoformans, serotype A was identified by API yeast reaction band and serology. Inoculation with mice and rats showed that their brains, lungs and livers were involved easily. Further identification as C.neoformans var.neoformans was obtained based on sequence analysis of ribosomal internal transcribed spacer region 2. The anti tuberculous therapy was stopped and anti fungal therapy was initiated at once. Intravenous and topical amphotericin B in combination with fluconazole were chosen in the initial therapy and itraconazole for maintenance. The nodules disappeared after 30 days and the last ulcer in the left tibia healed completely after 200 days. The anti fungal therapy was discontinued after 277 days and the patient was completely cured.

OBJECTIVETo evaluate and map the putative tumor suppressor loci on chromosome 5 involved in tumor progress or metastasis.

METHODSChromosome 5 of 83 patients with sporadic colorectal cancer was systemically screened. Fifteen microsatellite marker primers labeled with 3 different fluorescents were used to amplify the corresponding loci of the genome DNA. The PCR products were electrophoresed on a 377 PRISM sequencer and the fluorescent signals were analyzed with Genotyper and Genescan software.

RESULTSThe highest loss of heterozygosity (LOH) ratio was found at D5S416 (48.15%) on 5p and at D5S471 (38.71%) on 5q. The region (5q13.3 - 31), where D5S471 and 3 neighboring loci (D5S428, D5S2027 and D5S2115) reside, presented high frequent LOH.

CONCLUSIONThe deletion of APC, MCC, CTNNA1 and IL cluster in the 5q 13.3 - 31.1 area play important role in the tumorogenesis of colorectal cancer, and the expected existence of another novel tumor suppressor gene on 5p is possible.
