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.

BACKGROUND:Anterior cervical discectomy and intervertebral disc replacement have been extensively used in treatment of cervical degenerative disease. Its short-term therapeutic effects are encouraging, but it lacks of long-term and comprehensive evaluation.
OBJECTIVE:To observe the folow-up results of a group of cases of anterior cervical discectomy and Mobi-C intervertebral disc replacement for more than 5 years.
METHODS:A total of 25 cases of cervical spondylosis were treated in the 309 Hospital of Chinese PLA from January to September 2009. 19 of them were folowed up. Al patients received anterior cervical discectomy and Mobi-C intervertebral disc replacement. Twenty-three Mobi-C intervertebral disc prostheses were implanted. The range of motion was measured using lateral X-ray films during extension and flexion. Ectopic ossification was assessed by McAfee method. According to the cervical vertebra MRI images, the degeneration of adjacent segments was determined using Pearce classification. NDI score was used to evaluate the function of cervical spine. Pain improvement was evaluated using visual analogue scale score.
RESULTS AND CONCLUSION: A total of 19 patients were folowed up for 59-65 months, averagely 62 months. No significant difference in range of motion was detected before surgery and during final folow-up (P > 0.05). Ectopic ossification in two cases and the degeneration of adjacent segments in one case were found during final folow-up. No prosthesis loosening or displacement appeared. Visual analogue scale score and NDI score were significantly lower during final folow-up compared with that before surgery (P < 0.05). These results indicate that under the premise of reasonable choice of indications, the therapeutic effect of Mobi-C intervertebral disc replacement for degenerative cervical spondylosis was satisfactory in five-year folow-up. The range of motion was good, and the incidences of ectopic ossification and the degeneration of adjacent segments were low.

Objective To investigate the correlations between the level of blood lactic acid (Lac),lactate clearance rate (LCR) and emergency stratification Ⅰ or Ⅱ as well as the prognosis in patients.Methods A retrospective analysis was conducted.The clinical data of 370 critically ill patients with emergency stratification Ⅰ or Ⅱ accompanying with hyperlactacidemia admitted to emergency center of People's Hospital of Wuwei City during January 2013 to April 2015 were analyzed.The patients were allocated into two groups:Lac ≥ 10 mmol/L (n =181) and Lac 4-10 mmol/L (n =189).Base excess (BE),acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score and hospital mortality were compared between the two groups.The differences in initial Lac,6-hour LCR and APACHE Ⅱ score were compared between survival group and death group as well as emergency stratification Ⅰ and Ⅱ groups.The correlation between initial Lac,6-hour LCR and APACHE]Ⅱ score was analyzed by Pearson correlation method.Results ① With the increase in Lac level,the negative deviation extent of BE and APACHE Ⅱ score in critical patients were gradually increased [BE (mmol/L):-16.74 ± 8.21 vs.-5.98 ± 8.43,APACHE Ⅱ score:27.6 ± 5.6 vs.20.1 ± 4.8],and hospital mortality was increased [76.79％ (139/181) vs.43.39％ (82/189),all P ＜ 0.01].② The initial Lac and APACHE Ⅱ score of the death group were significantly higher than those of the survival group [initial Lac (mmol/L):8.81 ± 4.71 vs.4.43 ± 2.82,APACHE Ⅱ score:23.6 ± 5.6 vs.17.3 ± 3.7],and 6-hour LCR was significantly decreased [(12.26 ± 6.47)％ vs.(35.16± 10.63)％,all P ＜ 0.01].③ Patients in emergency stratification Ⅰ group had a higher initial Lac and a higher APACHE Ⅱ score but a lower 6-hour LCR level than those in emergency stratification Ⅱ group [initial Lac (mmol/L):8.7±2.6 vs.6.8±2.0,APACHE Ⅱ score:25.2±6.3 vs.16.3±4.7,6-hour LCR:(14.8±4.7)％ vs.(33.5±5.8)％,both P ＜ 0.01].④ It was shown by correlation analysis that initial Lac was significantly positively correlated with APACHE Ⅱ score (r =0.731,P =0.017) in 370 emergency critical ill patients,while 6-hour LCR was negatively correlated with APACHE Ⅱ score (r =-0.694,P =0.010).Conclusions The early arterial blood Lac of patients with emergency stratification Ⅰ was significantly higher than emergency stratification Ⅱ,and the 6-hour LCR in patients with emergency stratification Ⅱ was significantly higher than emergency stratification Ⅰ.Furthermore,the Lac level and LCR were simple and easy to implement as compared with APACHE Ⅱ score in emergency critical ill patients.

Objective To investigate T cell-mediated anti-HBV effects of dendritic cells (DCs) sensitized by HBsAg in patients with HBV infection in vitro. Methods DCs isolated from peripheral blood mononuclear cells of HBV patients were cultured and proliferated in vitro, and then were stimulated with pure HBsAg before DCs maturation, and co-cultured with auto-T lymphocytes after DCs maturation. The T lymphocytes were then harvested 5 days later and added into the supernatant of 2.2.15 cell cultures. The supernatants were collected on 1st, 3rd, 5th and 7th day, respectively. ELISA was employed to detect HBeAg and the secretion of HBsAg, as well as to measure the concentration of IFN-? and IL-12 in culture supernatents. Results The proliferation and cytotoxicity of auto-T cells were markedly enhanced in the antigen stimulated DCs group compared with that of DCs without loaded antigen and only T lymphocyte group (P

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.
