Objective To investigate the effects of Mycobacterium vaccae vaccine on immunological function and clinical character in elderly patients with stable chronic obstructive pulmonary disease (COPD). MethodsA total of 100 elderly patients with stable COPD were randomly divided into immunotherapy group (group A, n= 50) and non-immunotherapy group (group B, n= 50), and normal control group (group C, n = 50). The levels of peripheral blood T-lymphocyte subsets (CD3+ , CD4+, CD8+ , CD4+/CD8+ ratio), natural killer cells (NK cells), immunoglobulins (IgG, IgA, IgM) and cytokines (IL-6, IL-8, TNF-a) were measured respectively before and after therapy. Group A and B were followed up for 1 year, then the times of acute outbreak and hospitalization of patients in the two groups were also compared. Results The levels of CD4 + ,CD4+/CD8+ ratio and NK cells in group A, B were significantly lower before therapy (P<0. 05~0. 01=, and the levels of IL-6, IL -8, TNF-a and IgA were significantly higher than in group C (P<0. 01=. After treatment with Mycobacterium vaccae vaccine in group A, the levels of CD4+ , CD4+/CD8+ ratio and NK cells were significantly higher (P<0. 05-0. 01= and IL-6, IL-8, TNF-a and IgA were significantly lower than before treatment (all P<0. 01=. These levels showed no significant changes in group B after treatment (P>0. 05). After 1-year follow-up, the times of acute outbreak and hospitalization on patients were statistically lower in group A than in group B (P< 0. 01 ).ConclusionsMycobacterium vaccae vaccine can improve cellular immunity function and reduce the times of acute outbreak and hospitalization in patients with stable COPD, so it has a higher clinical application value.

OBJECTIVETo explore the feasibility and therapeutic effect of thinned posterior tibial artery free perforator flap for the reconstruction of soft tissue defects at dorsum of hands.
METHODSSix fresh adult lower limbs specimens were injected with red latex via arterial cannula and dissected. The number, distribution, branches, and outer diameter of posterior tibia artery perforators were observed. Based on the anatomic study, the perforator flaps were designed to reconstruct soft tissue defects at dorsum of hands and wrists. The redundant fat on the flaps was removed, but preserving the nutrient vascular system. 11 flaps were used with the size ranging from 2 cm x 5 cm to 10 cm x 14 cm.
RESULTS43 skin perforators of posterior tibial artery were observed in six lower limbs, 29 perforators with the outer diameter is greater than 0.5 mm when they threading over the deep fascia plane, on average every 4.8 bundles of sides. The mean outside diameter of perforating artery is (1.8 +/- 0.5) mm, and the length is (44 +/- 15) mm. 6 perforators were founded both in the second and fifth zone which could be used for anastomosis for its better diameters. All flaps survived completely without any complication at donor sites. 7 cases were followed up for 3-12 months. Both satisfactory functional and cosmetic results were achieved with a soft and thinned appearance.
CONCLUSIONSThe thinned posterior tibial artery free perforator flap has a reliable blood supply and good appearance. It is very suitable for the reconstruction of small or medium-sized defects at the dorsum of hands and wrists.

BACKGROUNDTumor involving the septum pellucidum is uncommon. Surgery as the main therapeutic procedure for this lesion is a challenge to neurosurgeons. We analyzed the clinical characteristics and pathological features of septum pellucidum tumor in 41 patients and compared the curative effects of frontal transcortical, trans-sulcal and interhemispheric transcallosal approaches.
METHODSClinical characteristics and the pathological features of septum pellucidum tumor were investigated retrospectively in 41 patients. The differences in postoperative residual rates, extents of tumors and resection of normal brain tissues after use of the three approaches in these patients were analyzed statistically.
RESULTSSeptum pellucidum tumor is more likely to attack young or middle-aged persons. The tumor mainly presents itself as a central neurocytoma or cerebral low-grade glioma in pathology and manifests as intracranial hypertension clinically. No difference was found in the extent of tumor resection but significant difference in the extent of normal brain tissue resection and in postoperative disability rate among the three approaches. The transcortical approach brought about the most serious injury to brain tissue and the highest disability rate, Whereas the frontal transcallosal approach the lightest injury and the lowest disability rate. The injury to brain tissue and the disability rate brought about by the front trans-sulcus approach were between the above two approaches.
CONCLUSIONSOperation is still regarded the major treatment for septum pellucidum tumor. Transcallosal and trans-sulcus approaches are fit with the concept of minimally invasive surgery, and transcallosal approach is the first choice for septum pellucidum tumor.

OBJECTIVETo investigate the association of interleukin 6 gene (IL-6) promoter region 634C/G (rs1800796) single nucleotide polymorphism (SNP) with the genetic susceptibility to endometriosis (Ems) in south Han Chinese women.
METHODSA case-control study was performed in 432 Ems patients and 499 control women to evaluate the SNP of IL-6 634C/G by using a fluorescent quantitative PCR-based high resolution melting (HRM) method.
RESULTSThere were statistical significances in the IL-6 634C/G alleles, whether or not to carry allele G and genotype distributions between Ems patients and control women (P=0.032, 0.014 and 0.045, respectively). Allele C enhanced the risk of Ems 1.057 times while allele G reduced the risk of Ems 0.835 time. Carrying allele G reduced the risk of Ems 0.822 time, whereas not carrying allele G enhanced the risk of Ems 1.143 times. Compared with genotype CC, the risk of Ems with genotype CG reduced 0.704 time (95% CI: 0.533-0.931). There was no significant difference in whether or not carrying allele G distribution between Ems patients and control women (P=0.729).
CONCLUSIONThe present study demonstrated significant association between the SNP of IL-6 634C/G and genetic susceptibility to Ems in south Han Chinese women.
