Objective To investigate the current status of medication compliance of patients with anky-losing spondylifis and analyze its related factors. Methods Seventy-four patients with ankylosing spondylitis were investigated about their general conditions,medication compliance and its related factors.The results were analyzed. Results Thirty-nine patients(52.7%) had good medication compliance while the rest 35 cases has poor medication compliance among which 24 patients with drug withdrawal exceeded 1 month.The medication compliance for patients with disease process of lower than 0.5 year,0.5 to 1.0 year,1 to 2 years and above 2 years was 82.0%,60.0%,25.0%and 31.0%.The logistic regression analysis showed that the disease process,dis-ease knowledge and media advertisement were the main influencing factor for medication compliance,while the age,sex,marital status,education background,adverse reaction,satisfaction degree with medication effect, economic conditions and depression were not major influencing factors. Conclusions About half of patients with anky-losing spondylitis had poor medication compliance,especialy with disease process of above 1 year.The main in-fluencing factors include disease process,disease knowledge and media advertisement.

Objective To evaluate the accuracy and feasibility of 64-slice spiral CT (64SCT) in assessing coronary artery disease.Methods A total of 30 suspected patients (male 21 cases, female 9 cases, and mean age of 54.6 years) were undergone both 64SCT and selective coronary angiography (SCA). Volume redering (VR) ,multiplanar reconstruction (MPR), maximum intensity projection (MIP) and transverse section were reconstructed. The results of coronary reconstructions were compared with SCA to analyze the accuracy of the 64SCT in detecting coronary artery stenoses.Results In the 396 segments of coronary artery(diameter≥2 mm)of 30 patients, 385 were judged to be evaluable by 64SCT. The evaluable rate was 97.2%. The sensitivity, specificity, positive predictive value and negative predictive value of the 64SCT in detecting coronary artery stenoses(≥50% of stenosis) were 96.22%, 94.56%, 89.44% and 96.88%. The accuracy rate of 64SCT in detecting ≥50% stenosis of coronary artery was 95.90%.Conclusion 64SCT has high accuracy in detecting coronary artery stenoses, as a noninvasive method,it can be used for screening patients with known or coronary artery diseases.

BACKGROUND:The adhesion between muscle tendon and surrounding tissue after tendon restoration is one hot topic in clinic.
OBJECTIVE:To construct a deep flexor tendon transection model in the third toe of female Leghorn chicken and to explore the effect of peritenon transplantation on the prevention of tendon adhesions.
METHODS:After the transection models were successful y established, the third toe of left claw was taken as experimental group A. The transected tendon was sutured, the tendon anastomosis end was wrapped with the peritenon of the deep flexor tendon from the ipsilateral fourth toe (experimental group B). The third toe of right claw served as control group A, the transfected tendon was sutured and restored with the peritenon. The fourth toe of right claw was taken as control group B. Gross observation and histological observation of the tendon were performed.
RESULTS AND CONCLUSION:At 28 days postoperatively, gross observation and histological observation of Leghorn chicken were performed and compared using the Kruskal-Wal isH and Nemenyi test, respectively. The results showed that, the therapeutic effect was better in experimental group A than in control group A (P<0.05), but slightly poorer compared with control group B and experimental group B (P<0.05). The postoperative effect was better in experimental group B than in control group A (P<0.05) and showed no significant difference between experimental group B and control group B (P>0.05). The flexor function was evaluated and compared with the least significant difference t-test. The results showed that the postoperative effect was better in experimental group A than in control group A (P<0.05), but slightly poorer compared with control group B and experimental group B (P<0.05). The postoperative effect was better in experimental group B than in control group A (P<0.05) and showed no significant difference compared with control group B (P>0.05). Peritenon transplantation can effectively prevent tendon adhesions and has little impact on normal tendon sliding.

OBJECTIVEThis study aims to evaluate the quality of life (QOL) of patients who underwent resection of oral cancer and reconstruction by free anierolateral thigh perforator flaps (ALTF).

METHODSA total of 32 patients with oral and maxillofacial malignancies who had undergone the resection of oral cancer and reconstruction by ALTF were retrospectively analyzed. At 12 months postoperatively, the QOL of these patients was assessed by using the 14-item oral health impact profile (OHIP-14) and the medical outcome study short form-36 (SF-36) questionnaires.

RESULTSA total of 32 questionnaires were collected. In SF-36, the highest scoring domains were bodily pain (78.58 ± 14.82), physical functioning (72.08 ± 27.86), and the role of physical (60.00 ± 42.63), whereas the lowest scoring domains were role-emotional (41.67 ± 39.62), followed by mental health (50.75 ± 13.07) and health transition (54.17 ± 21.75). In OHIP-14, the lowest scoring domains were social disability (34.50 ± 11.32) and handicap (36.04 ± 12.05), indicating the functional recovery was better; and the highest scoring domains were physical pain (73.50 ± 18.96) and psychological discomfort (60.17 ± 20.66), indicating the functional recovery was worse.

CONCLUSIONThe ALTF is an ideal selection for the reconstruction of oral defects after cancer resection. In using this flap, the basic social need of patients after surgery can be satisfied. Moreover, the appearance and the functions of chewing, deglutition, and speech can be restored in varying degrees. Thus, ALTF can improve the patients' QOL.

A case of porokeratoma is reported.A 35-year-old man presented with asymptomatic verrucous nodules on both buttocks for more than 1 year.Skin examination at the first visit revealed two pea-sized verrucous nodules on bilateral buttocks.The lesions recurred at the primary site 3 months after surgical resection.At the second visit,there were 4 verrucous nodules,including 1 on the left buttock and 3 on the right buttock.Histopathological examination showed a well-defined lesion characterized by acanthosis and compact,thick orthokeratosis with seveal broad cornoid lamellae.A diagnosis of porokeratoma was made.The lesion was resected again followed by oral acitretin treatment.No recurrence was observed during 15 months of follow up.

Objective To investigate the effects of UDP glucuronosyltransferase (UGT) 1A9 I399 C ＞ T single nucleotide polymorphism on postoperative sedation with propofol in patients undergoing breast surgery.Methods One hundred and fifty-two ASA Ⅰ or Ⅱ female patients,aged 20-50 yr,weighing 50-70 kg,scheduled for elective benign breast tumor excision under general anesthesia,were enrolled in this study.The polymorphic sites of the UGT1A9 I399 C ＞ T allele were analyzed by polymerase chain reaction-restriction fragment length polymorphism.The patients were assigned to one of 3 groups according to their genotypes:wild homozygote (C/C) group,mutation heterozygote (C/T) group and mutation homozygote (T/T) group.During induction and maintenance of anesthesia,propofol was given by target-controlled infusion with the plasma concentration (Cp) of 3μg/ml.Blood samples were taken at 60 min after target-controlled infusion of propofol was started for determination of the Cp of propofol using high-performance liquid chromatography.The time when OAAS was 4 after stopping the infusion of propofol was recorded and the BIS value and effect-site concentration of propofol were also recorded at this time.The time when BIS value was 80 was recorded and the effect-site concentration of propofol was also recorded at this time.Results Genotyping analysis revealed that genotype distribution of UGT1A9 I399 C ＞ T polymorphism was C/C 24 cases,C/T 96 cases and T/T 32 cases.The T allele frequency was 53％.The C allele frequency was 47.4％.There was no significant difference in the Cp of propofol,time when OAAS was 4,BIS value and effectsite concentration of propofol when OAAS was 4,time when BIS value was 80 and effect-site concentration of propofol when BIS value was 80 among the three groups (P ＞ 0.05).Conclusion UGT1 A9 I399C ＞ T single nucleotide polymorphism is not the genetic factor contributing to the individual variation in the patient' s response to postoperative analgesia with propofol in patients undergoing breast surgery.

OBJECTIVE: To determine the sensitivity of cetuximab induced apoptosis in laryngeal squamous carcinoma cells Hep-2, and to evaluate the synergistic killing effects and regulation mechanism of cetuximab alone or cetuximab in combination with chemotherapeutic agents (cisplatin) or radiation means on Hep-2 cells. METHOD: To investigate the cytotoxicities of cetuximab, cisplatin and radiation, cell counting kit-8 (CCK-8) assay was used for the detection of cell growth inhibition ratio, and fluorescence activated cell sorter FACS for the apoptotic rate and cell cycle distribution. RESULT: Cetuximab had inhibitive effect on Hep-2 cells within a certain range of concentration in a time- and dose-dependence manner. The inhibition concentration 50% (IC50) of cetuximab on Hep-2 cells for 24 h was 1 036.84 microg/ml. For application of cisplatin and radiation, the apoptotic rate of Hep-2 cell was higher by combining with cetuximab than their single or combined administration. Moreover, the cell cycle arrested at G0/G1 phase. CONCLUSION Laryngeal cancer Hep-2 cells was sensitive to the cetuximab induced apoptosis. Cetuximab combined with cisplatin and/or radiation can increase the antiproliferative effects on Hep-2 cells. These findings suggest the synergistic combination of cetuximab and cytotoxic agents was sequence depended.

Objective To explore the protective effcets of Schisandra chinensis extract (SCE) in paraquat (PQ)-induced pulmonary fibrosis in mice ,and its intrinsic molecular mechanisms thereof. Methods A total of 108 mice were randomly allocated into six groups (n=18):control group, model group, low concentration of SCE group (200 mg/kg), medium concentration of SCE group (400 mg/kg), high concentration of SCE group (800 mg/kg) and vitamin C group (100 mg/kg). Except control group, mice were given by intragastric administration with PQ (100 mg/kg) and administered with SCE and Vitamin C once per 24 h after PQ modeling. Mice were sacrificed at 7, 14 and 21 d after modeling. Six mice were executed at different time points. The degree of lung tissue inflammation and fibrosis were observed by HE staining and Masson staining. The mRNA and protein expression levels of transforming growth (TGF)-β1, interleukin (IL)-6 and IL-17 in lung tissue were determined by RT-PCR and ELISA respectively. Results (1) Compared with control group, the lung tissue of model group showed a large number of inflammatory cell infiltration, space congestion, and its inflammation scores increased at 7 and 14 days after modeling (P<0.05). At the same time, compared with model group and vitamin C group, inflammation scores were significantly decreased in medium concentration of SCE group and high concentration of SCE group (P<0.05). (2) Compared with control group, collagen fibers and the degree of fibrosis were significantly increased in model group ,while pulmonary fibrosis were decreased in medium concentration of SCE group and high concentration of SCE group at 14 and 21 days after modeling (P<0.05). (3) With the extension of modeling time, both mRNA and protein expressions of TGF-β1 were obviously elevated, IL-6 decreased and IL-17 reduced after the first increase in PQ group. Compared with PQ group, levels of three cytokines mRNA and protein expression in medium concentration of SCE group and high concentration of SCE group changed as follows:IL-6 level was markedly decreased at 7 and 14 days after modeling;TGF-β1 level was markedly increased at 14 and 21 days after modeling. However, IL-17 level was markedly decrease at three time points(P<0.05). Conclusion SCE can relieve PQ-induced lung inflammation and fibrosis by suppressing TGF-β1, IL-6, and IL-17 expressions.
