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 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 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 clarify the association between chondroitin-4-O-sulfotransferase-3 (CHST13) and hepatoma metastasis by the research of differential expression of CHST13 in MHCC97-H and MHCC97-L human hepatocarcinoma cell lines,which have high and low metastatic potential,respectively,and to confirm novel target of hepatoma metastasis and anti-tumor therapy.Methods The differential expressions of CHST13 in MHCC97-H and MHCC97-L human hepatocarcinoma cell lines were analyzed by real-time PCR,Western blot.CHST13 was silenced using RNA interference approach to detect the invasive ability in vitro and tumorigenicity in vivo in MHCC97-L cells.Results The expression of CHST13 was different in MHCC97-L cells,as compared to those in MHCC97-H cells.Knockdown of CHST13 expression enhanced MHCC97-L cells invasion and tumorigenicity both in vitro (t =2.8,P =0.005) and in vivo (t =2.5,P =0.01).The quantity of cells which crossed basement membrane increased [(30 ± 3):(14 ± 2)],and the average weight of tumor increased [(0.9 ± 0.10) g:(0.5 ± 0.06) g].Conclusion The differential expressions of CHST13 in human hepatocarcinoma cell lines correlate with tumor invasion and tumorigenicity,and it is expected to be a novel target for the treatment of hepatocellular carcinoma.

Objective To compare the influence of the continuous airway humidification with microp-ump and the discontinuous dripping technique on patients. Methods Randomized grouping method was adopted, 25 cases with tracheotomy in the observation group used continuous airway humidification with micro-pump, 24 cases in the control group used dripping technique via airway for airway humidification. The two groups were compared retrospectively. Results The oxygen saturation rate in the observation group increased compared with that of the control group, sputum callus formation, irritating cough, airway bleeding and pul-monary infection was significantly lower than those of the control group. Condusious The effect of continu-ous airway humidification with micro- pump is superior to the traditional method of inconsistent endotracheal dripping, the former can also decrease nursing workload of airway humidification.

Objective To investigate the influence of cognitive training on patients with Alzheimer's disease. Methods 30 patients received cognitive function training based upon drug treat-ment. Patients were assessed with mini- mental state examination (MMSE) and functional independence measure(FIM) before and after treatment, the results went through t test. Results After training, cog-nitive function and self- care ability after treatment greatly alleviated compared with those before train-ing. Conclusions Cognitive training can improve cognitive function and self- care ability of patients with Alzheimer's disease and facilitate their life quality.

Objective To investigate the application of dual volume reconstruction translucent imaging in performing stent- assisted coil embolization for intracranial aneurysm embolization treatment. Methods During the period from Nov. 2011 to Sep. 2012, a total of 30 patients with intracranial aneurysm were admitted to authors’ hospital. Stent-assisted coil embolization was carried out in all patients. The number of all the stent point-marks visualized on routine 2D-DSA, on rotational angiography (3D-RA) and on dual volume reconstruction translucent images were determined, and the results were compared between each other of the three imaging methods. Results A total of 34 stents (206 stent point-marks in total) were implanted in the 30 patients. Of the 206 stent point-marks, 2D-DSA, 3D-RA and dual volume reconstruction translucent image could clearly display 146 (70.8%), 123 (59.7%) and 190 (92.2%), respectively. Statistically significant difference in the displaying rate of the stent point-marks existed between each other among the three imaging methods (P < 0.05). Conclusion Dual volume reconstruction translucent imaging can distinctly display the location of the stent marks, which is of great value in guiding the performance of intracranial stent implantation surgery.

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 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.
