Objective:To analyze manifestation of spine tuberculosis in CT and MRI, compare two kinds of techniques respectively of diagnosis advantage. Methods: Retrospective analysis of 18 cases confirmed by the surgical operation and pathology imaging of CT and MRI Material of spine tuberculosis. Results: The CT can nicely show that the bone destruction, the bone increase osteoslerosis, sequester and new-born formation and narrow of intervertebral disc, swelling paraspinal soft tissue and psoas major muscle abscess, spinal canal of bone is narrow, calcification. Although CT can show intervertebral disc involvement and terminal plate of vertebral body destruction in sagittal reconstruction, not equal to MRI sensitive, Evaluating intervertebral disc involvement and area of paraspinal soft tissue swells, changed in early days spine tuberculosis of valuation, MRI had obvious advantage. Conclusion: Combining CT and MRI can reflect the image of spine tuberculosis to learn a characteristic completely and be advantageous to diagnosing and discriminate diagnosis of spinal tuberculosis.

Objective To observe the postoperative analgesic effects of perioperative intravenous parecoxib in gerontal patients undergoing laparoscopic cholecystectomy. Methods A prospective,randomized, double-blind, placebo-controlled, parallel group study was performed. The 40 American Society of Anesthesiologists (ASA) Ⅰ or Ⅱ patients (aged 60-80 years) undergoing elective laparoscopic cholecystectomy under general anesthesia were randomly allocated to 2 groups (n = 20,each): the parecoxib group received intravenous parecoxib 40 mg at 10 minutes before incision and 12 hours and 24 hours after incision; however, the placebo group received 5 ml normal saline instead of parecoxib at the same time. The intensity of algesia was measured using visual analogue scale (VAS)scores (1-10, 0 = no pain, 10 = worst pain), and was recorded at 2, 4, 6, 12, 24 hours after operation. The patients' global evaluation of postoperative analgesia was recorded and compared between the two groups. Results The VAS scores at the different time points were significantly less in parecoxib group than in placebo group (all P＜ 0.05). The patients' global evaluation of postoperative analgesia was higher in parecoxib group than in placebo group [(8. 1 ± 1.2) scores vs.(5.2± 0. 9 ) scores, t = 7. 402, P ＜ 0. 05]. Conclusions Intravenous parecoxib can effectively relieve postoperative algesia and improve postoperative analgesia after laparoscopic cholecystectomy.

Objective To investigate the effect of different time administration of parecoxib sodium on the postoperative analgesic efficacy in patients undergoing thoracic surgery. Methods This was a prospective,randomized, double-blind, placebo-controlled study. Sixty ASA Ⅰ orⅡ patients aged 17-83 yr undergoing pulmonary lobectomy were randomly allocated to one of 3 groups (n=20 each):A, B and C groups. Group A received normal saline 2 ml at 30 min before skin incision and the end of operation. Group B received iv parecoxib sodium 40 mg at 30 min before skin incision and normal saline 2 ml at 30 min before the end of operation. Group C received normal saline 2 ml at 30 min before skin incision and iv parecoxib sodium 40 mg at 30 min before the end of operation. All the patients received patient-controlled intravenous analgesia with morphine and VAS score was maintained≤3. The patients were followed up after operation.The morphine consumption, patients' global evaluation of the postoperative analgesia (0-100, 0=worst pain, 100=no pain), nausea and vomiting, body temperature , volume o chest drainage, hepatic, renal and blood coagulation function were recorded. Results Compared with group A, the morphine consumption was significantly reduced, the patient' s satisfaction score increased and body temperature decreased in B and C groups(P＜0.05 or 0.01). There was no significant difference in the morphine consumption, patient's satisfaction score and body temperature between B and C groups(P＞0.05). No significant difference was found in the parameters of hepatic, renal and blood coagulation function, volume of chest drainage and incidence of nausea and vomiting among the three groups(P＞0.05).Conclusion When postoperative analgesia is assisted with iv parecoxib sodium 40 mg given at 30 min before skin incision or at 30 min beforethe end of operation,the efficacy is similar,and both can improve the postoperative analgesic efficacy of morphine and reduce fever after operation in patients undergoing thoracic surgery.

Objective To investigate the safety and efficiency of a reinforced laryngeal mask airway(LMA) with drain tube in elderly patient undergoing endoscopic sinus surgery.Methods Sixty elderly patients were selected and randomly divided into two groups:a reinforced LMA group (group R,n=30)and a reinforced endotracheal tube group(group T,n=30).Observation items include the difficulty degree of device insertion,the time for successful insertion,the number of attempts required for successful insertion,fiberoptic view of glottis,the difficulty degree of gastric tube insertion,oropharyngeal leak pressure(OLP),ventilatory indicators at a certain time,haemodynamics during insertion,the blood stain on the mask were compared between the two group.The postoperative complications 1,6,24 hours after operation were recorded.Results There were no significant differences in general conditions,the successful insertion rate at first attempt,the total success insertion rate,airway quality and the anesthetic drug dosage between the two groups.The insertion time was shorter in group R than in group T [(34.1± 13.0 s)vs (45.4± 15.6 s),t =5.274,P=0.001].The incidence of cough during extubation was less in group R than in group T [0％ (0/30) vs.53.3％(16/30),x2 =21.222,P=0.000].Conclusions The reinforced LMA with drain tube is safe and effective for elderly patients during endoscopic sinus surgery.

Objective To study the genetic diversity of Fritillaria thunbergii,a traditional Chinese herb in Zhejiang Province in China.Methods The genetic diversity of six representational populations of F.thunbergii including 32 individuals was investigated by amplified fragment length polymorphism(AFLP) maker technique.Results The genetic diversity was revealed as follow: the Nei′s genetic diversity index(He) 0.169 0?0.175 7,Shannon′s information index(I) 0.269 8?0.245 3,percentage of polymorphic loci(PPB) was 76.85% at the species level;Ht 0.169 0?0.030 9,and Hs 0.150 8?0.024 0,I 0.233 3?0.261 9, PPB was 50.38% at population level.The genetic differentiation index(Gst) was 0.107 6,Nm 4.147 0.The result of dendrogram of six populations indicated that Dongyang and Yongkang populations shared the minimum genetic distance(0.015 0),they were classified into a group,and Xiangshan and Jinyun populations shared the maximum genetic distance(0.032 4).Conclusion The genetic diversity of F.thunbergii cultivated in Zhejiang Province is very rich,which could ensure the long-term survival of F.thunbergii.But the genetic diversity of F.thunbergii is relatively higher in population levels while lower at the species levels and the degree of genetic differentiation occured among the populations is not significant.The germplasm resources are relatively stable among these six populations.These populations could be used to breed the fine strains of F.thunbergii as the bases.

Objective To observe the genetic structure of cultivated Scrophularia ningpoensis in Zhejiang Province.Methods The genetic structures of six typical S.ningpoensis populations were analyzed by fluorescence AFLP marker.Results Bands(12 552) were generated by seven pairs of AFLP primer combinations,of which 8 808 were polymorphic,and the polymorphic rate was 70.17%.The variety ranges of PPB among different populations were 41.67%—55.56%,and 47.30% in average.I was between 0.190 8—0.238 3,and 0.221 8 in average.Ne was between 1.201 4—1.280 6,and 1.236 9 in average.Gst was 0.127 1,Nm was 3.432 4.UPGMA Cluster analysis showed that the six populations can be divided into two clusters,as that of Tiantai,Jinyun,and Jingning were one sub-cluster,and Dongyang,Pan′an,and Xianju were another one sub-cluster.Conclusion There is a relative high genetic diversity level in cultured S.ningpoensis of Zhejiang Province.Genetic differentiation exists among populations,but it exists in population mostly.There is a relative high genetic intercommunion among populations.The genetic distance is not related to the geographic environment.

Objective To study the association between human papillomavirus (HPV) genotypes and viral load and clinical features of verruca vulgaris.Methods Tissue samples were collected from 48 outpatients with verruca vulgaris,and DNA was extracted from these tissue samples.To determine the genotype of HPV,PCR was performed to amplify the L1 fragment of HPV with universal primers followed by bidirectional sequencing and BLAST.The genotyping results were validated by PCR with type-specific primers.Real-time fluorescence-based quantitative PCR was conducted to measure the viral load of HPV,and hematoxylin and eosin (HE) staining to observe histological changes in these tissue specimens.Results The L1 fragment of HPV was amplified from 35 out of the 48 tissue specimens.Of the 35 L1-positive specimens,32 harbored HPV 7,1 harbored HPV 57,and 2 harbored both HPV 2 and HPV 7.Multiple lesions were observed on extremities in the patient infected with HPV 57,but on the head,face and trunk in the patients coinfected with HPV 2 and HPV 7.There were no significant differences in HPV viral load or vacuolated cell number between patients with single lesions and those with multiple lesions,or between patients with a clinical course of ＜ 6 months and those with a clinical course of 6-12 months.However,HPV viral load tended to decrease one year after the onset,and there was pronounced hyperkeratosis and less vacuolated cells in lesions of long duration (more than 2 years) compared with those of short duration (less than 2 years).Conclusions HPV 7 appears to be the most common HPV genotype associated with verruca vulgaris,and HPV 7 infection usually occurs on the head and face.For verruca vulgaris of less than 1 year,neither HPV viral load nor vacuolated cell number is associated with the count or clinical course of warts.

Objective To explore the effect of transitional care model (TCM) on the prevention of complications in patients with severe cerebral infarction. Methods Sixty patients with severe cerebral infarction were randomly divided into the experiment group and the control group, 30 cases in each group. The control group was given conventional nursing and the observation group received TCM. The two groups were compared in terms of the incidence of complications and re-admission rate. Result The incidence of complications and the rate of re-admissions in the experiment group were significantly lower than those of the control group (P<0.05). Conclusion TCM can reduce the incidence of complications in patients with severe cerebral infarction, lower the incidence of hospital admission, relieve the pain of patients and improve the quality of life of patients.

Objective To investigate the neuromuscular block effect of intravenous injection of cisatracurium in myasthenia gravis patients with different ages.Methods Fifteen geriatric patients defined as geriatric group(≥ 65 years old)with ASA Ⅰ-Ⅱ scheduled for video-assisted thoracoscopic (VATS)thymectomy with Ⅱ b MG and fifteen young-middle aged Ⅱ b MG patients defined as youngmiddle aged group (20-50 years) with paired sex,clinical symptoms,duration of symptoms,preoperative treatment regimen,anesthesia management and surgical time were included.Neuromuscular block was monitored with TOF Watch acceleration instrument.After induction of intravenous anesthesia,0.05mg/kg Cisatracurium was administrated intravenously,followed by increments of 0.015 mg/kg until T1/T0 was less than 5％ for each patient.A double-lumen bronchial tube was intubated when T1/T0 was less than5％.0.015 mg/kg cisatracurium was injected during the operation when T4/T1 was achieved to 25％.The dose of cisatracurium,the duration of blockade maintenance,duration of clinical action and neuromuscular block recovery index were obtained.Results There were no significant differences in tracheal doses of cisatracurium [(0.058 ± 0.013)mg/kg vs.(0.053±0.009)mg/kg]and the duration of blockade [(31.5±9.6)min vs.(40.0±19.8)min] between geriatric group and young-middle age group (P＞0.05).The duration of clinical action of cisatracurium [(21.6±6.7)min vs.(33.7±13.4)min]and the time to achieve a TOFr of 25％ were significantly shorter in geriatric MG group than those in young-middle aged MG group (P=0.045,0.037).The geriatric MG group were administrated more increments of ciastracurium than the young middle aged MG group during surgery (P=0.025).There was no significant difference in the time to achieve a TOFr of 70％ [(49.3±16.4)min vs.(57.4±34.7)min] and 90％ [(61.6± 19.2)min vs.(64.3±35.9)min] between geriatric MG group and young-middle aged MG group (P＞ 0.05).Conclusions The duration of clinical action of cisatracurium in geriatric MG patients was shorted than that in young-middle aged MG patients which was different with neuromuscular block effect in normal patients.It is suggested to do more studies to estimate the influence of age on cisatracurium and other muscle relaxants in MG patients.
