Objective To observe the curative effect of botulinum toxin A(BTX-A)repeated intramuscular injection for treatment of serious spastic cerebral palsy.Methods Thirty cases with serious spastic cerebral palsy received local repeated intramuscular injection. The interval time was 3 months. The dose of BTX-A was 4 U/kg.The muscle tone was assessed with the modified ashworth scale and range of motion with physical rating scale(PRS).The indexes were evaluated before injection and 3 months after the second injection. Paired-samples t-test was used in the statistic analysis.Result The muscle tone and PRS had remarkable improvement after second therapy with BTX-A(P

Objective To produce a hybridoma secreting stable monoclonal antibodies against Aβ22-35 and to develop a detection method for the assay of Aβ. Methods Spleen cells from Balb/cmice immunized with Aβ22-35-KLH were fused with mouse myeloma cells SP2/0. The techniques of immunoprecipitation and western blotting plus ECL were used to investigate the levels of Aβ in the rat brain. Results Two strains of hybridomas (3A8 and 3B2) secreting stable monoclonal antibodies raised against Aβ22-35 were obtained. The subtypes of Aβ22-35 were IgG3. The levels of Aβ in young and older rat brain were 9.8±2.8 and 13.36±2.65 (pmol/12mg brain tissues, x±s), respectively. Conclusion The Aβ22-35 mAb obtained had high titres and specificity. The levels of Aβ in the older rat brain were significantly increased as compared with the young one (P<0.05).

The tools used for the literature quality evaluation are introduced. The common evaluation tools that are publicly and extensively used for the evaluation of clinical trial literature quality in the world are analyzed, including Jadad scale, Consolidated Standards of Reporting Trials (CONSORT) statement and Grades of Recommendations Assessment, Development and Evaluation (GRADE) system and the others. Additionally, the present development, updates and applications of these tools are involved in analysis.

Objective To study the rationality and possibility of 64 slice spiral CT in the examination of the temporal bone at low dose.Methods The same CT technique and temporal bone mode as those for clinical CT were used,two cranium specimens(four ears)were scanned with Somatom Sensation 64-slice spiral CT at different mA(380,300,200,160,120,80),and muhi-planar reformation was performed.The CT dose index at different mA groups were measured by 10 cm pencil ionization chamber and head dose phantom.Four anatomic structures on axial images(subarcuate fossa,tendon of tensor tympani, facial recess,etc),four anatomic structures on coronal images(scute,crista transversa,fenestra cochleae, etc)and six anatomic structures on double oblique images(malleus,incus,stirrup bone,upper bony semicircular,etc)were chosen to evaluate and grade the reformation images among different mA groups,and to determine the minimum mA value.Ten ears of five patients were used to test the validity of the minimum mA value.Results CT radiation dose was significantly reduced from(47.8?2.7)to(20.1?2.0)raCy (P

OBJECTIVESTo explore whether the angiotensin I -converting enzyme (ACE) I/D (insertion/ deletion) polymorphism is associated with the susceptibility to high altitude pulmonary edema (HAPE) in the Han Chinese.
METHODSOne hundred and forty-seven HAPE-p (HAPE patients) and 193 HAPE-r (HAPE resistants) were enrolled from the Yushu earthquake reconstruction workers in Qinghai province where the altitude is over 3 500 m above sea level. Blood samples were collected from each of the HAPE-p and HAPE-r groups. Information about physiological phenotypes was obtained via fieldwork investigation. The ACE-I/D polymorphism in HAPE-p and HAPE-r was detected by polymerase chain reaction (PCR).
RESULTSThe SaO2 was significantly lower while HR was significantly higher in HAPE-p group than those in HAPE-r group. The genotype frequencies of ACE-I/D for II, ID, DD in HAPE-r and HAPE-p groups were 0.430, 0.446, 0.124 and 0.435, 0.469, 0.095, respectively, the allelic frequencies of I and D were 0.650, 0.350 and 0.670, 0.330, respectively. The OR of ID, DD and D alleles relative to II for HAPE was 0.961 (0.610-1.514), 1.322 (0.634-2.758) and 1.080 (0.783-1.489). There was no significant difference of the genotypic and the allelic frequencies in ACE-I/D polymorphism between HAPE-p and HAPE-r groups.
CONCLUSIONSThere is no relation between ACE-I/D polymorphism and HAPE in the Han Chinese.

Investigation of simvastatin and its related substances was carried out using a reversed phase ultra performance liquid chromatography/tandem mass spectrometry method. The identification of impurities in simvastatin was performed with a triple-quadrupole mass spectrometer, with an electrospray ionization (ESI) source in the negative/positive ion mode. A total of 12 compounds were characterized in commercial samples, among which 2 impurities had never been reported. All the impurities were deduced based on the MS fragment pathways of simvastatin and the biosynthetic pathway of lovastatin. This work provides very useful information for quality control of simvastatin.

Endophytic fungi played an important role in the growth of its host plant. To investigate the mycorrhizal characteristics and the distribution of fungi in the root, an endangered wild plant-Dysosma versipellis was collected and observed by electron microscope. The results showed that the host was closely associated with endophytic fungi. The fungi were mainly distributed in the epidermis and cortex. The aseptate and septate fungi with swollen hyphae were observed in some cell of the cortex. The result provides a reference for the study of mycorrhizal structure of Dysosma genus and the interaction between the fungi and its host.

ObjectiveTo analyze the clinical characteristics and treatment of severe acute respiratory syndrome (SARS).MethodsDuring epidemic period of SARS,all suspected patients were isolated and treated at very early stage. Clinical symptoms, signs and changes of the chest film were observed carefully to make early diagnosis and begin early intervention. 14 SARS cases with definite diagnosis were treated by Western Medicine combined with Chinese Traditional Medicine.3 cases of them with severe type were treated by timely technical ventilation,which was nasotracheal intubition guided with fibronchoscope,with the principle of low tide volume and high PEEP to improve oxygen combination.ResultsAll patients were cured to discharge. Only two cases of mild pulmonary fibrosis were found after 2 months' follow-up. None of the medical workers taking part in rescuing and treating SARS patients and none of the family members of the patients were infected.ConclusionDuring SARS epidemic period,early isolation,early diagnosis,early combined treatment of Western Medicine and Chinese Traditional Medicine,and prompt technical ventilation intervention on severe cases are important factors to successfully rescue and treat SARS patients.
