Objective To explore the effects and feasibility of minimal local analgesic dose of hyperbaric levobupivacaine in elderly patients undergoing unilateral spinal anesthesia during lower limb orthopedic surgery.Methods Seven hundred and fifty-six elderly patients who scheduled lower limb orthopedic surgery were assigned to levobupivacaine group (383 patients) and bupivacaine group (373 patients) by random digits table method.Haemodynamic change were monitored before,during and after anesthesia.The level and duration of sensory and motor block in each group were evaluated.Results Compared with bupivacaine group,the sensory block and motor block onset time was significantly longer in levobupivacaine group [(5.9 ± 1.4) min vs.(4.2 ± 0.3) min,(11.7 ± 3.0) min vs.(9.1 ± 3.3) min] (P ＜0.05),but the motor block duration was shorter [(152.8 ± 17.5) min vs.(195.4 ± 18.7) min] (P ＜ 0.05).The scores of maximum motor block in levobupivacaine group was significantly lower than that in bupivacaine group[(1.1 ±0.3) min vs.(2.3 ±0.6) min](P＜ 0.05).There was no significant difference in peak sensory block and haemodynamic between two groups (P ＞ 0.05).Conclusions Although levobupivacaine may be less potent than bupivacaine,it may be preferred for elderly patients with lower limb surgery because of satisfactory spinal anesthesia,good hsemodynamic stability and fast motor block regression.

Tumor stage and lymph node involvement are the most important prognostic factors for patients with locally advanced cervical cancer. For cervical cancer, gynecologic oncologists generally apply the criteria of the International Federation of Gynecology and Obstetrics(FIGO). However, in the current FIGO 2018 staging system, stage ⅢC is based only on the anatomical location of metastatic lymph nodes, without considering local tumor factors and other lymphatic status parameters, which limits its prognostic significance to a certain extent. The aim of this article is to summarize the influence of local tumor factors and different lymphatic status parameters on prognosis and treatment options for stage ⅢC cervical cancer.

Objective To study the changes and roles of serum anticardiolipin antibodies (ACA) and plasma TXB_2, 6-K-PGF_ 1? in acute cerebral infarction (ACI).Methods Serum ACA and plasma TXB_2, 6-K-PGF_ 1? levels were measured by enzyme linked immunosorbent assay (ELISA) in 143 patients with ACI and were compared with 59 healthy controls. The patients with ACA positive in ACI group were further divided into subgroupⅠwith stroke risk factors and subgroup Ⅱ without stroke risk factors. The levels of TXB_2 and 6-K-PGF_ 1? in the two groups were compared.Results The positive rate of ACA in ACI group (46.85%) was significantly higher than that in control group (11.63%)( P

Objective To establish a three-dimensional finite element model and make mechanical analysis of "V"-type atlantoaxial reduction and internal fixation. Methods According to "V"-type atlantoaxial and internal fixation,based on screw-type Ⅱ design parameters,and using Pro/E 2001 and MSC.Patran 2005 software,we set up a finite element model and calculated the region containing the node scope of the force as the sites binding and 100N mechanics adding. Results The model looked realistic,geometric similarity.The deformation stress field mainly concentrated in the reset device V-tip arm bending and stability.The strength of its maximum stress was 4.78MPa,and the scope had 2794 nodes.V-type wing of the acute angle point of convergence of the premises to bear the stress intensity followed.It was 0.31MPa,and the scope had 1953 nodes.V-type wing by the end of edge was the smallest for the 1.22?10-3MPa,and there was the scope of 1730 nodes. Ⅱ-shaped fixed nail stress concentrated at the central parts of tooth and the art on both sides of teeth,with maximum stress intensity of 1.68?10-2MPa,and there was the scope of 1146 nodes. Conclusion The reduction and fixation devices to load at the time of recovery deformation forces and mechanical characteristics adapted to Ni-Ti shape memory alloy material functions and super-elasticity completely,which meets the clinical needs.

Objective: To study the super high-dose chemotherapy in drug-resistance Ⅲ B osteasarcoma with autologous bone marrow transplantation. Methods: The chemotherapy was carried out in 4 patients with drug-resistance Ⅲ B osteosarcoma. The autologous bone marrow was harvested before chemotherapy and reinfused after chemotherapy when the serum concentration of methotrexate reduced to 1.0?10~(-7) mol/L. The chemotherapy included ,methotrexate 500 mg/kg , adriamycin 25 - 75 mg/m~2 and vincristine 1.5 mg/m~2 with low dose citrovorum factor rescue. Results: Four patients tolerated the chemotherapy well and felt better than before. The pulmonary metastases had various degrees of reduction in 2 patient and calcified in 1 patient, but progressed in 1 patient. Conclusion: Super high-dose chemotherapy has good response in drug-resistance ⅢB osteosarcoma and is safe with autologous bone marrow transplantation. This regimen is worth to be further studied and be used in ⅡB osteosarcoma.

Objective To determine the applicability of locally continuo u s application of alendronate for the prevention of prosthesis aseptic loosening. Methods Using the method of in vitro cell culture to detect the influence of a lendronate with different concentrations(1?10－11mol/L,1?10－9mol/L,1?10－7mo l/L,1?10－6mol/L,1?10－5mol/L) on the proliferation, secretion and osteogenesi s of human osteoblasts as well as the effect of the motility, respiration, phago cytosis and bactericidal ability. Results Higher concentration of alendronate(1 ?10－6mol/L,1?10－5mol/L) improved local antiinfection ability, but inhibited osteogenesis (1?10－5mol/L). Lower concentration(1?10－11mol/L,1?10－9mol/L,1 ?10－7mol/L) inhibited the bactericidal effect of neutrophils, but stimulated o steogenesis(1?10－11mol/L,1?10－9mol/L). Conclusion Locally continuously usin g alendronate around prosthesis to prevent and treat aseptic loosening must be h andled with discretion. Its concentration should not be below 1?10－6mol/L in the early period after arthroplasty operation, but the concentration should be 1?10－11mol/L or 1?10－9mol/L in the late period.

Objective To investigate the expression of nerve tissue protein S-100(S-100)and gap junctional protein connexin 43(Cx43) in rat adenohypophyseal folliculo stellate cells(FSCs) under the influence of ovariectomized osteoporosis(OVX-OP) and estrogen replacement therapy(ERT). Methods Sixty 10 month old female rats were randomly divided into sham operation control group(Sham), ovariectomy group (OVX) and ovariectomy+ERT group (OVX+ERT). L4-6 bone mineral density(BMD) of the animals in Sham group and OVX group were measured by dual energy X-ray absorptiometry(DEXA) at the end of 6 weeks after operation. From 7th week, rats in OVX+ERT group were treated with nilestriol(1 mg?kg -1?week-1) for 6 weeks. Rat L4-6 BMD in OVX+ERT group were measured at the end of 12 weeks after operation. Expression of S-100 and Cx43 in FSCs was detected using immunofluorescent histochemistry and laser scanning confocal microscopy(LSCM). Results L4-6 BMD was significantly lower in OVX group (0.193?0.006) g/cm2 than in Sham group(0.211?0.013) g/cm2 and in OVX+ERT group (0.204?0.010) g/cm2 (P

Objective To evaluate the result of anterolateral interbody fusion combined with transpedicle fixation for patients with kyphosis due to tuberculosis of the thoracic spine. Methods There were totally 17 patients, 11 male and 6 female in this study. The average age was 36.4 years, ranging from 23 to 56 years old. All tuberculous lesions were located in low thoracic spine, two vertebral bodies were involved in 9 patients and three vertebral bodies involved in 8 patients. The average kyphosis angle was 25 degrees, ranging from 15 to 34 degrees. Mild neurological function deficiency (Frankel Grade C or D) were present in 5 patients. All patients were treated with one stage posterior transpedicle fixation and anterolateral interbody fusion combined with 9 month antituberculous medication. Results All patients were followed up for 2 to 4 years postoperatively. All incisions were healed up primarily. Interbody fusion was achieved in all patients from 4 to 6 months after operation. All patients were cured and there was no recurrence within follow up period. The average kyphosic angle was 7 degree postoperatively, and the average correction of kyphosis angle was 18 degree, which was maintained well within follow up period. Patients with neurological function deficiency achieved complete recovery one year after operation. Conclusion Anterolateral interbody fusion combined with transpedicle fixation provides rigid fixation and good stability for early fusion and facilitates tuberculous kyphosis correction. This one stage procedure is effective in decreasing duration of antituberculous medication and increasing curing rate of spinal tuberculosis.
