Objective To observe the clinical efficacy of electroacupuncture plus needle-cupping in treating lumbar intervertebral disc herniation (LIDH). Method Eighty patients with LIDH were divided into an observation group and a control group by random number table, 40 in each group. The observation group was intervened by electroacupuncture plus needle-cupping, while the control group was by electroacupuncture plus cupping. The clinical efficacy, Modified Japanese Orthopaedic Association Scores (M-JOA) and Visual Analogue Scale (VAS) were observed and comparatively analyzed. Result The total effective rate was 95.0% in the observation group, significantly different from that of the control group (P＜0.05); the M-JOA scores increased significantly (P＜0.05) and VAS scores dropped significantly (P＜0.05) in both groups, and the changes of the scores were markedly different between the two groups (P＜0.05), indicating that the improvement in the observation group was more significant. Conclusion Electroacupuncture plus needle-cupping can produce a significant therapeutic efficacy in treating LIDH.

Objective To investigate the clinical features, therapy and prognosis of elderly patients with newly diagnosed acute promyelocytic leukemia (APL). Methods The clinical features of 21 elderly patients and 89 patients aged ＜60 with newly diagnosed APL were retrospectively analyzed. Additionally,elderly patients were divided into different groups according to the count of white blood cell (WBC). Results There were no significant differences between elderly patients and patients aged ＜60 in the aspect of sex (male/female: 11/10 vs 47/42), WBC count (high initial WBC: 23.8 % vs 16.9 %), the percentage of bone marrow blasts plus promyelocytes (0.83±0.11 vs 0.83±0.12), complete remission (CR) rate (71.4 % vs 84.3 %),the time of CR occurrence (35.7±10.1 vs 39.1±13.5), the occurrence of retinoic acid syndrome(RAS) (14.3 % vs 22.5 %), disseminated intravascular coagulation (DIC) (52.4 % vs 34.8 %) as well as 2 years overall survival rate (72.7 % vs 80.0 %) (P ＞0.05). Of the 21 elderly patients who received inductive treatment, 5 with high initial WBC and 16 without high initial WBC. The incidences of DIC, early death in high initial WBC group were 80 %, 60 % respectively, which were higher than the group without high initial WBC (43.8 %,18.8 % respectively), whereas CR rate for the group with high initial WBC (40.0 %) was lower than that for the group without high initial WBC (81.3 %). Conclusion Elderly patients with APL could have fine prognosis as well as patients aged ＜60. The results of inductive treatment of elderly patients in high initial WBC group were poor as compared with the group without high initial WBC.

objective To analyze the killer cell immunoglobulin-like receptors(KIR)gene polymorphism of pre-eclampsia patients and approach the correlation between KIR genes and pre-eclampsia.Methods The KIR gene polymorphisms of 71 pre-eclampsia patients and 100 healthy pregnant women were detected by PCR-SSP.The KIR2DL4 mRNA level in placentas from pre-eclampsia and gestational normal pregnancies were quantified by real time RT-PCR.Forty pre-eclampsia patients and 38 healthy pregnant women were detected for single nucleotide polymorphisms(SNP)in the gene coding and joint areas between introns and extrons by directly sequencing techniques of KIR2DL4 genomic DNA.Finally,all alleles and genotypes of KIR2DL4 gene were case-control studied.Result Distributions of some relatively activating KIR genotypes shewed a significant association with pre-eclampsia.Real-time RT-PCR showed that KIR2DL4 mRNA can be measured both in placenta of women with pre-eclampsia being of pre-eclampsia waft significantly lower than that of normal pregnancy.only as much as 0.276 times that of controls.We identified 18 polymorphisms,of which,7 were first reported.But no significant differences in genotype distributions or allele frequencies were observed in these SNPs between cases and controls.Conclusion The distributions of some relatively activating KIR genotypes showed a significant association with pre-eclampsia,which indicates that the polymorphism of KIR genes may be associated with the genetic predisposition to pre-eclampsia.And because the expression of KIR2DL4 mRNA in the placentas of cases wag significantly lower than control group,it is speculated that the decrease of KIR2DL4 expression in placenta may participate in the pathogenesis of pre-eclampsia.

Objective To explore the mechanism and effects of basic fibroblast growth factor( bFGF)on skin wound healing. Methods Fibroblasts( FB)were isolated from normal skin and hypertrophic scar and cultivated by direct adherence method. FB were then treated with different concentrations of bFGF(0,0. 1,1,10,100,1 000 ng·mL-1 )and cultivated with serum-free medium for 72 hours. The proliferation and apoptosis of FB in each group were detected by cell counting and trypan blue staining. Content and gene expression of typeⅠand type Ⅲ collagen and fibronectin were determined by ELISA and RT-PCR,respectively. Results bFGF promoted the proliferation of FB at low concentrations promoted apoptosis of FB at higher concentrations. The proliferation of FB from hypertrophic scar was slower than that from the normal skin. bFGF significantly inhibited type Ⅰ collagen production from hypertrophic scar FB but not from the normal skin. Moreover,bFGF up-regulated fibronectin expression in the normal fibroblasts,but not in the hypertrophic scar. No change in type Ⅲ collagen expression and production was observed in FB from either source. Conclusion bFGF has differential effects and mechanisms on FB of the normal skin and hypertrophic scar,suggesting that bFGF may play a role in early phase of skin wound healing and scar formation.

Objective To illustrate the clinical relevance of distinct PML-RARα fusion gene isoforms in acute promyelocytic leukemia (APL). Methods The nested reverse transcriptase polymerase chain reaction (RT-PCR) was used to detect the long (L) or short (S) PML-RARα fusion gene isoforms in 92 newly diagnosed APL so as to evaluate the clinical feature, therapeutic reaction and prognosis of the two fusion gene isoforms. Results PML-RARα fusion gene was positive in all 92 APL patients, of which 52(56.5 %) was L type and 40 (43.5 %) was S type. There were no significant differences between L type and S type in the aspect of sex, age, white blood cell count,the percentage of bone marrow blasts plus promyeloeytes and chromosome before treatment. And there were no significant differences between the two isoforms in complete remission (CR) rate, the time of getting CR as well as the occurrence of retinoic acid syndrome (RAS), disseminated intravascular coagulation (DIC), intraeranial hemorrhage. Also, there were no significant differences in overall survival rate (OS) and relapse-free survival rate (RFS) between the two isoforms. Conclusion PML-RARα fusion gene isoforms in APL were not correlated with clinical therapeutic effect or prognosis.

Objective To explore the effect of comprehensive nursing intervention on the rehabilitation of patients with schizophrenia,and to provide reference for clinical nursing.Methods Sixty-seven long-term hospitalized patients with schizophrenia received 6 months comprehensive nursing intervention.The instruments of the nurse observation scale for inpatient evaluation(NOSIE),insight and treatment attitude questionnaire (ITAQ),scale of social function in psychosis inpatients (SSPI) were administered both at the start and the end of intervention.Result After 6 months of treatment,the scores on mental disorder,recovery of social ability and treatment compliance and recovery or selfconcicousness increased as compared with pre-intervention (all P＜0.001).Conclusion The comprehensive nursing intervention can improve the mental symptoms and social function,alleviate their depression and promote mental rehabilitation of the patients with schizophrenia.

Objective To investigate the therapeutic effect of the ligustrazine injection on rats models of experimental high intraocular pressure induced by retina ischemia-reperfusion.Methods Thirty two SD rats were divided into four groups randomly:the ligustrazine group,the model group,the normal group and the vitamine E group.The ischemia-reperfusion model is established by increasing intraocular pressure to 110mmHg in rat eyes.The ligustrazine group was treated with the ligustrazine injection,the vitamine E group with gastric gavage of vitamine E,and the model and normal groups with distilled water.The period of treatment was 7 days.The histopathologic changes were observed under the optical microscope and the electron microscope,meanwhile the SOD and MDA were measured.Results After ischemia for 60 min and reperfusion for 48 h,the cells in retinal ganglion cell layer and inner nuclear layer were thinned under optical microscope,perinuclear karyopyknosis and apoptotic bodies appeared in retinal ganglion cell layer and inner nuclear layer under electron microscope,SOD activity decreased and MDA level increased.After treatment,the morphology of retinal ganglion cell layer and inner nuclear layer was improved obviously,SOD activity increased and MDA level decreased.It is suggested that ligustrazine injection exerts anti-ischemic and anti-hypoxic and cytomembrane stabilizing effects to a certain extent.Conclusion The ligustrazine injection is an effective traditional Chinese medicine in treating retinal ischemia.

The electronic structure of a Lindqvist type [Mo7O24]6- anion with 5 different types of counterion (K+, Na+, NH4+, [NH3Pr]+ and [NH3Pri]+) was calculated by using the Discrete Variational Method coupled with Density Functional Theory (DFT-DVM). It could be concluded through variance analysis to the calculated results that the type of counterion does not influence remarkably the electronic structure of [Mo7O24]6- anions. Perhaps it can be used to explain the experiment fact that the polyoxomolybdate structure of the Mo7O24 framework is apparently of critical significance to antitumor action. On these grounds we forecast that two other lindqvist type heptamolybadates(their counterions are Na+ and [NH3Pr]+ respectively) may also exhibit antitumor activities.
