Circulating tumor cells(CTCs)are essential for establishing metastasis and recurrence in non-small cell lung cancer(NSCLC). With the development of detection technique,results from recent studies suggest that CTC level could be a supplement for TNM staging system and a prediction marker of prognosis and therapeutic efficacy,and even could be applied for risk assessment of early NSCLC. Furthermore,as a non-invasiveliquid biopsy,detection of CTC can reflect the molecular biology and genetics characteristics of the primary tumor,and subsequently assist in selecting an optimal individualized treatment.

Objective: To evaluate the effect and safety of neoadjuvant chemotherapy combined with PA-MSHA injection for breast cancer patients. Methods: An open randomized controlled clinical trial was con-ducted. Fourty patients with breast cancer were randomly assigned to neoadjuvant chemotherapy group (the control group, n=20) and neoadjuvant chemotherapy combined with PA-MSHA injection group (the experi-ment group, n=20). The evaluation of therapeutic effect was carried out when the treatment was completed. Kamofsky score was recorded before and after therapy. Venous blood was drawn before and after therapy and immune function (IFN-γ, IL-2, IL-4, and IL-10) and other indicators (Caspase-3, VEGF, MMP-2 and MMP-9) were measured by double antibody ELISA test. Adverse effects of PA-MSHA during therapy were ob-served and recorded. Results: The overall response rate (RR) in the experiment group was significantly higher than that in the control group (P<0.05). No significant difference was found in the pathologic complete remis-sion (pCR) between the experiment group and the control group (P>0.05). In the experimental group, pCR was significantly different before and after therapy (P<0.01). The score in the experimental group was signifi-cantly higher than that in the control group after therapy (P<0.01). With the treatment of chemotherapy and PA-MSHA injection, IFN-γ and IL-2 levels were significantly higher while IL-4 and IL-10 levels were significant-ly lower in the experiment group (P<0.05). A significant increase in serum Caspase-3 and a significant de-crease in serum VEGF, MMP-2 and MMP-9 (P<0.05) after therapy were also observed in the experimental group. The level of serum MMP-9 was decreased significantly (P=<0.05) after therapy in the control group. Con-clusion: Neoadjuvant chemotherapy combined with PA-MSHA injection can significantly improve the RR of breast cancer patients, enhance their cellular immune function, induce the apoptosis and restrain the metasta-sis of breast cancer cells. The PA-MSHA has been proved to be an ideal supplementary therapy for breast cancer.

Objective Retrospective analysis of experience of distal upper limb autologous arteriovenous fistula for hemodialysis access and treatment of arteriovenous fistula occlusion was conducted.Methods To summarize the clinical data of 214 cases of initial autologous arteriovenous fistula and 22 cases of treatment of arteriovenous fistula occlusion were carried out from Aug.2007 to Mar.2011,comparing the success rate and long-term patency rate.Results Two hundred and fourteen cases of initial autologous arteriovenous fistula,in which 168 cases were cephalic vein-radial artery side-to-side anastomosis at snuffbox,46 cases were cephalic vein-radial artery end-toside anastomosis at proximal wrist,the success cases were 203 (94.8％),the failed cases were 11 (5.2％),limb edema in 82 cases and there was no steal syndrome and heart failure.The primary patency rate was 95.2％ at 1 year and 91.3％ at 2 years.There were 22 patients accepted treatment of arteriovenous fistula occlusion,in which,8 cases were embolectomy due to acute occlusion,8 cases were thrombectomy and balloon dilation because of anastomotic stricture and thrombosis and 1 failed,5 cases were proximal anastomosis again after chronic occlusion.Conclusions Autologous arteriovenous fistula of the distal upper limb,especially from the place of snuffbox which is the preferred method for autologous arteriovenous fistula.And deal with arteriovenous fistula occlusion actively can often extend the usage time of the autologous blood vessels and improve the life quality of patients.

Objective To observe the clinical efficacy of percutaneous vertebroplasty (PVP) with percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fracture(OVCF) by systematic review. Methods From September 2005 to March 2009,46 cases of fresh OVCF were treated. Patients were divided into 2 groups (A, B), according to Jikei grade, Genant semiquantitative method, injury vertebra number. Twenty-five cases(group A)were treated by PVP,8 males and 17 females with the age of 52 - 78 years (average 69). Vertebra segment of fracture was within T6 - L5 (14 in case thoracical vertebrae and 11 lumbar vertebrae). Twenty-one cases(group B)were treated by PKP,There were 6 males and 15 females with the age of 54 - 82 years (average 71). Vertebra segment of fracture was within T6 - L4 (12 in case thoracical vertebrae and 9 lumbar vertebrae). The clinical efficacy, incidence rate of complication, the anterior height of vertebrae body,visual analogue pain scale(VAS) ,ease of pain were measured preoperatively and at 6 weeks, 3 and 6 months and 1 year postoperatively between the two groups. Results All the patients were followed up for 12 -45 months with an average of 23.5 months. The average recovery of anterior height of vertebrae body was respectively(85.95 ± 4.31) % in group A and (93.64 ± 3.35) % in group B,which statistically difference in vertebral height between two groups (P ＜ 0.05). No statistical significant difference was seen in VAS, analgesic durg (AID) and ease of pain complication between two groups (P ＞0. 05). Statistical significant difference was noted in pre-postoperatively between intra-two groups (P ＜0. 05). Conclusions PVP and PKP can quickly relieve pain and enhance vertebral stability in treating thoracolumbar OVCF according to evaluation parameter, and have the similar therapeutic efficacy in treatment of OVCF with minimal invasion. However, PKP is superior in the recovery of vertebral height.

Objective To examine the changes in calcium currents in isolated dorsal root ganglion (DRG) neurons in rats with neuropathic pain.Methods The neuropathic pain model was established by modified spinal nerve ligation (SNL) 2 to 4 weeks before electrophysiologic recording. The rat DRG neurons were enzymatically dissociated. Whole -cell patch clamp technique was used to record Ca2+ current.Results In large DRG neurons the mean peak value of electric current-voltage ( Ⅰ - Ⅴ) curve was decreased significantly from ( - 105?13) pA/ pF in control group ( n = 9) to ( - 66?10) pA/pF in neuropathic pain group ( n = 11) (P 0.05) . Conclusion In neuropathic rat Ca2+ currents in large DRG neurons are decreased and the voltage dependence of the fast component of inactivation is shifted to more depolarized potentials. These changes may contribute to hyperalgesia and allodynia of neuropathic pain.
