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 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.

Objective To study the clinical features of acute pancreatitis (AP) in elderly patients. Methods The elderly AP patients from January 1993 to October 1999 in our hospital were studied retrospectively. Results There are 83 cases with a male to female ratio of 1 5∶1 and a median age of 72 7 years.AP was diagnosed in 83 cases for 107 times which included 80 times of mild AP and 27 times of severe AP 13 patien with APts were diagnosed for more than one times.Abdominal pain was the primary symptom in 94 4% patients. 6 patients had no pain 53 0%(44/83) and 84 6%(11/13) patients had cholelithiasis and recurrent AP respectively.60 5% and 72 6% patients were diagnosed by type B ultrasonic and CT respectively . Conclusions In elderly AP patients,abdominal pain was the primary symptom, but a part of patients had no typical symptoms.Cholelithiasis including biliary sludge was an inducement especially in recurrent AP patients. Type B ultrasonic and CT examination were important means in diagnosis.

Objective To introduce the operative procedure of prosthetic disc nucleus(PDN)re-placement and investigate its clinical effectiveness in the treatment of lumbar disc herniation.Methods Nine cases of lumbar disc herniation were treated with PDN replacement from March2002to April2002.There were6males and3females,the average age of the patients was33.4years ranging from22to48years.The interval between the onset of the symptoms and the diagnosis was averagely18.4months,ranging from8months to3.6years.All of the patients were evaluated by anteroposterior and lateral radiography,computer-ized tomography and,if necessary,magnetic resonance imaging.The low back pain was predomi nant in two patients,the low back pain associated with radicular leg pain in6patients.The height of disc space became narrowed in varying grade.The operated level was at L 4-5 in6patients,L 5 S 1 in3patients.The standard pos-terior approach was used in8patients;the anterior lateral retroperitoneal approach was adopted in1patient.8cases were implanted with a single PDN,and1case with a couple of PDNs.Results All patients were followed up12to13months(average12.3months).The estimated intraoperative blood loss ranged from50to150ml (mean120ml ),and the total operation time ranged from45to120min(mean60min).The patients wore a brace for the first6weeks.Based on Oswestry low back pain and dis ability scores,the clinical successful rate was88.9%.The average percentage of the postoperative to preoperative disc height was128%.The slight displacement of PDN was observed in2patients,however there was no change of lumbar spinal mo bility.1patient had a bad recovery of back and leg pain.Conclusion PDN re placement can improve clinic symptoms,increase disc height and restore the normal lumbar motion as well.Its clinical effectiveness is excellent in short-term observation.

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
