ObjectiveTo investigate the influence of transverse and longitudinal lower segment caesarean section on the outcome of newborn, postpartum haemorrhage and ratio of complications in placenta previa. MethodsPlacenta previa with lower segment transverse caesarean section( 117 cases) were taken as control group, meanwhile, the lower segment with longitudinal section (142 cases ) as experimental group. Their operational complications, amount of bleeding during and after operation and outcome of the perinatal period were analysed.Results No significant difference in age, parities, gestational weeks, the types of the placenta praevia and the locus of placenta between the two groups were found( P>0.05), while there were significant difference in the amount of bleeding during and after operation, the need of using gauze ribbon to stop bleeding, section splitting and rate of hysterectomy after caesarean section(P<0.01). ConelusionLower segment longitudinal caesarean section in placenta praevia not only shows less bleeding during operation and lower rate of postpartum haemorrhage, but also avoids using gauzes to stop bleeding and causes lower rate of hysterectomy after caesarean section, so it can be the first choice when determining the style of section in placenta praevia.

Objective To observe the effects of low dose irradiation (LDI) on autoiogous CIK cell proliferation, phenotype and killing activity in tumor patients, and to provide the evidence for clinical application of adoptive immunotherapy with CIK cells. Methods Peripheral blood mononuclear cells (PBMC) were separated from 10 patients with malignant tumor, and CIK cells were cultured with different cytokines. (1) After 10 d culture, C1K cells were irradiated with different doses as 30, 50, 80, 100 and 200 Gy of X-rays was also detected. The CIK cell proliferation and killing activity were measured with 3H-TdR incorporation assay and 3H-TdR release assay, respectively and the percentage variation of CD3 +CD56 + were measured with flow cytometry after 24 h. ( 1 ) Autologous CIK cells were irradiated with 80 mGy X-rays. At different culture time ( 12, 24, 48, 72 h) after irradiation, the killing activity was measured with 3H-TdR release assay. (3) The effect of 3d low dose irradiation of 80 mGy X-rays on thekilling activity of CIK cells was also detected. Results After the CIK cells were irradiated with different doses as 50, 80, 100, 200 mGy of X-rays, the CPM values were 20 048.6 ± 2332. 2 ( t = 2.2, P <0.05), 21 832.2 ±2975.9 (t=3.5, P<0.01), 21 000.3 ±2451.1 (t=3.3, P<0.01), 19908.1 ±2051.0 ( t = 2.2, P < 0.05 ), respectively and the proliferation of CIK cells were significantly higher than that of control group. The CD3 + CD56 + cell percentage of 50, 80, 100 mGy groups were ( 30.3 ±3.8)% (t=2.3, P<0.05), (32.3±3.4)% (t=4.2, P<0.01), (29.742.9)% (t = 2.4, P<0.05 ), respectively. The killing activity of CIK cells of 80, 100 mGy groups were 55.2 ± 5.0 ( t = 3.3, P < 0.01 ), 52.8 ± 4.1 ( t = 2.3, P < 0.05 ), respectively. The killing activity of CIK cells up-regulated significantly at 24 h, dropped to normal levels at 48 h and 72 h. After 80 mGy X-ray irradiation for 3 consecutive days, the killing activity of CIK cells at different time points were 55.2 ± 5.3 (t = 2.6, P <0.05),61.9 ± 4.4 (t = 4.7, P <0.01), 67.2 ±5.7 (t = 5.7, P <0.01) for 24, 48, 72 h,respectively. Conclusions LDI might have the hormesis effect on CIK cells.

Bacteria isolated from rotten hides,one identified as Pseudomonas aeraginosa later, were shown to decompose fresh hides completely in 48 hours at room temperature. Strongly collagenolytic activity was detected when native collagen from calfskin was used as substrate. The optimal reaction pH value and temperature of the collagenace produced by P.aeraginosa are 7.5 and 32℃ respectively. EDTA and EGTA inhabit the collagenolytic activity severely while PMSF has little effect on it. Not only media components but also fermentation conditions have differents effect on the production of this collagenolyic enzyme.

Objective: To observe the clinical effect of Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method versus ordinary acupuncture on superficial fascia for treating neck type cervical spondylopathy in Kyrgyz. Methods:A total of 64 Kyrgyz patients conforming to the diagnostic criteria of neck type cervical spondylopathy were included. The patients were randomized into a Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture group and a conventional acupuncture group, with 32 cases in each group. Patients in the Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture group were treated with Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method to stimulate the superficial fascia, the stimulation sites were primarily located at bilateral sides of the cervical vertebra as well as the trigger points in shoulder-neck region; patients in the conventional acupuncture group were punctured at the same acupoints, with twirling reducing method, and the depth of insertion was determined by the treated region. Patients in both groups received treatment every day for a succession of 5 d as a course, with a 2-day interval between 2 courses, and the whole treatment lasted for 3 courses. After 3 courses of treatment, the McGill pain questionnaire (MPQ) and neck disability index (NDI) were measured to compare the clinical effect between the two groups. Results: After treatment, scores of MPQ and NDI scale dropped when compared with those before treatment, and the differences showed statistical significance (allP<0.05); scores of MPQ and NDI in the Jin Gou Diao Yu (gold-hook-fishing) acupuncture group were substantially lower than those in the conventional acupuncture group, and the differences showed statistical significance (allP<0.05). The total effective rate was 96.9% in the Jin Gou Diao Yu (gold-hook-fishing) acupuncture group and the cured rate was 78.1%, which were higher than 81.3% and 40.6% in the conventional acupuncture group, and the differences showed statistical significance (bothP<0.05). Conclusion: Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method by stimulating superficial fascia to treat cervical spondylopathy in Kyrgyz can produce a better clinical effect than conventional acupuncture treatment, and is effective in improving pain and stiffness in patients, and thus is worth clinical popularization.
