AIM: To study the effect of garlicin on protecting nonalcoholic fat liver in rats induced by high fat diet and explore the pathogenesis involved. METHODS: According to the dosage of garlicin and diet, fifty SD rats were randomly divided into five equal groups: normal control group, model control group and garlicin (10, 20, 30 mg/kg) groups. Apart from the rats in normal control group, the rats were all fed with high fat and high cholesterol diet. After 12 weeks, the levels of serum endotoxin (ETX), total cholesterols (TC), triglyceride (TG), superoxide dismutase (SOD), malondialdehyde (MDA), transaminase and free fatty acids (FFA) were detected. The levels of MDA, SOD, glutathione hormone (GSH) in hepatic tissue were also detected. Then the features of live pathology were observed. RESULTS: The levels of ETX, TC and TG in garlicin groups were significantly lower than those in model control group (P

Objective:To study the effect of natural antioxidant ?-carotene(?-C) combined with vitamin E and C supplement on cellular oxidative damage in aged people. Method:Three hundred subjects aged from 60 to 75y,128 males and 172 females were randomized into 5 groups:group 1(VE 200mg/d+VC 300 mg/d+?-C 16.7 mg/d) ,group 2(VE 200 mg/d+VC 300 mg/d+?-C 8.4 mg/d) ,group 3(VE 200 mg/d+VC 300 mg/d+?-C 5.6 mg/d) ,group 4(VE 200mg/d+VC 300mg/d) ,group 5(VE 5 mg/d) . The trial lasted 16 weeks. All subjects were asked to record the nutrients intake daily. The investigators followed-up and supervised the subjects irregularly. The samples of blood and urine were collected at the beginning and end of the trial. The proliferation of lymphocytes was detected by MTT and H2O2-induced erythrocyte hemolytic degrees were measured before and after the trial. Thefluidity of erythrocyte membrane was evaluated by fluorescence polarization(?) and microviscosity(?) . O6-MeG was analyzed by high performance capillary zone electrophoresis. Results:The proliferation of lymphocytes was increased and H2O2-induced erythrocyte hemolytic degrees were decreased from group 1 to group 4 at the end of trial with significant difference compared with control group 5. The ? and ? values were lower in 1 to 4 groups at the end of trial. O6-MeG was significantly lower in group 1 to 4 group at the end of trial,and group 1 lower than group 4. Conclusion:Different doses of natural antioxidant ?-carotene supplement combined with vitamin E and C could improve the function of erythrocyte and the proliferation of lymphocytes,and decrease DNA alkylating damage.

OBJECTIVE: To explore the effects of different analgesia methods after UPPP. METHOD: Ninety cases of patients uvulopalatopharyngoplasty were divided into 3 groups randomly, and 30 cases in each group. The group A was the blank control group without any analgesia measures. The cases in group B were treated with intramuscular injection of parecoxib sodium 40 mg after surgery immediately, and continued injecting 40 mg after 12 hours, 24 hours and 36 hours respectively. 100 mg tramadol replaced 40 mg parecoxib sodium in group C. The VAS scoring was performed after surgery 12, 24, 36, 48, 72, 96 hours in 3 groups, and we observed adverse reaction such as lethargy, nausea, vomiting, dizziness, skin rash and so on. RESULT: The group B and C reduced the pain significantly compared with blank control group. The pain scores in group B were significantly decreased than that in group C (P<. 05). CONCLUSION The analgesic effect of parecoxib sodium after UPPP is significant and better than tramadol. It is worthy to use widely in clinical due to its better effect and less side effect.

OBJECTIVETo evaluate the long-term survival of multidisciplinary treatment based on thoracic surgery for cervical esophageal squamous cell carcinoma.

METHODSThe clinical characters and follow-up data of forty-one cervical esophageal cancer patients who accepted multidisciplinary treatment based on surgery with preservation of pharynx and larynx were retrospectively reviewed, and the long-term survival was compared with 480 non-cervical esophageal cancers who accepted surgery in the same period done by the same surgical team.

RESULTSThere were 28 males and 13 females with a mean age of 62 years old. In the cervical esophageal cancer group, 30 patients accepted neoadjuvant chemotherapy, 25 patients accepted adjuvant chemotherapy, and 21 patients accepted both. Six patients received postoperative radiation. Four patients underwent exploratory surgery alone, and 37 cases underwent radical surgery and cervical anastomosis. One case died during the perioperative period. The 1-, 3-, 5- and 8-year survival rates were 96.8%, 52.6%, 35.1%, and 35.1% in the 36 patients with cervical esophageal cancer who underwent radical surgery, and were 85.0%, 54.3%, 45.0%, and 36.7% respectively in the 457 non-cervical esophageal cancer patients. There was no significant difference between the cervical group and non-cervical group(P=0.91).

CONCLUSIONCervical esophageal cancer should be treated in a multidisciplinary approach to obtain satisfactory long-term outcomes.

OBJECTIVETo summarize the surgical outcome of patients with small cell esophageal carcinoma(SCEC).

METHODSClinical data of patients with esophageal carcinoma were retrospectively collected from March 2000 to March 2011 at the Thoracic Surgery Department of the Peking University Cancer Hospital. Data included tumor characteristics, staging, treatment, response, short-term outcome, and long-term survival.

RESULTSA total of 546 patients with esophageal carcinoma were identified, among whom there were 15 patients with SCEC(2.7%). Fourteen cases received multimodality treatment based on operation and one underwent operation alone. Four patients had preoperative chemotherapy and 10 had postoperative chemotherapy. Four patients had postoperative radiation. After excluding one case of postoperative death within 3 months, the median overall survival was 14.3 months(range, 4 to 99 months), significantly worse than those with non-SCEC(42.2 months, P<0.05).

CONCLUSIONSCEC is rare and the outcomes are poor. It should be considered as a systematic disease.

BackgroundThe influence of glaucoma on the quality of life in patients is of increasing concern for ophthalmologists in recent years. However,some studies demonstrated that different types of questionnaires about quality of life have various disadvantages. Therefore, to accurately and fully assess the influencing factors of quality of life in glaucoma patients is very important. ObjectiveThe present study was to survey the self-reported visionrelated quality of life(QOL) in glaucoma patients by means of utility analysis and to tentatively analyze its influencing factors. Methods Patients with glaucoma were recruited from a single tertiary ophthalmic department. Standard face-to-face interviews were conducted. Utility values of linear rating scale ( RS ) and time trade-off ( TTO ) were calculated to evaluate the self-reported vision-related QOL of the patients. The correlations of the utility values with the patients' general and ophthalmologic characteristics were also analyzed. This survey was approved by the Ethic Committee of Beijing Tongren Hospital. Oral informed consent was obtained from the subjects before the study.ResultsA cross-sectional study was designed. A total of 86 glaucoma patients were enrolled in this study with 62 male and 24 female, with a mean age of 44. 67 years old. The mean utility values measured by RS and TTO were 0. 62± 0. 19 and 0. 77 ± 0. 12, respectively, and no evidential correlation was found between these two values ( r =0. 074, P=0. 499 ). The RS value was associated with daily visual acuity,mean deviation(MD) of visual field and the history of trabeculectomy. Neither daily visual acuity nor MD showed a significant correlation with the TTO value. Age, work status and educational background contributed to higher utility value for the TTO method. After adjusting for age, work status and educational level,patients with visual acuity in the worse-seeing eye better than 0. 3 showed a higher TTO value than those with less than 0. 3. Conclusions Utility analysis possesses the advantages of convenience and sensitivity. RS utility value is easily affected by the Objective visual status and surgery history in glaucomatous patients,which reflects the subjective assessment of patients'visual quality. However, TTO value is primarily associated with age,work status and education level rather than visual function in glaucoma patients,which is therefore subjective assessment of the disease-related quality of life. These Results indicate that visual function impairment is not a determining factor for the QOL of glaucoma patients.

OBJECTIVETo understand antibody responses to and RNA sequences of Hantavirus in patients with hemorrhagic fever renal syndrome (HFRS) in Yantai areas and to demonstrate the type of the prevalent viruses caused HFRS.

METHODSSerum specimens collected at acute and convalescent stages from 90 patients with HFRS and IgM and IgG antibodies against Hantavirus were detected with ELISA, and cross plaque reduction neutralizing tests were performed to detect neutralizing antibody. Viral RNA was extracted from the patients? sera by using Trizol method and nested PCR was utilized to amplify the specific segments of the viral cDNA and the products of the PCR were TA cloned and then the nucleotide sequences were determined.

RESULTSThe IgM antibody was positive in 82.2% (88/107) of the patients while the IgG antibody was positive in 85.7% (66/77) of the patients. Both the serologic and sequence analyses demonstrated that the epidemic of HFRS in Yantai areas was caused by mixed types of Hantavirus. The prevalent strains of Hantavirus had higher homology with the strains isolated in Korea than with those isolated previously in China.

CONCLUSIONSThe serologic and sequencing analyses indicated that the epidemic of HFRS in Yantai areas was caused by mixed types of Hantavirus dominated by type SEO.

OBJECTIVETo assess the clinical efficacy on post-stroke speech disorder treated with acupuncture and psychological intervention combined with rehabilitation training.

METHODSThe multi-central randomized controlled study was adopted. One hundred and twenty cases of brain stroke were divided into a speech rehabilitation group (control group), a speech rehabilitation plus acupuncture group (observation group 1) and a speech rehabilitation plus acupuncture combined with psychotherapy group (observation group 2), 40 cases in each one. The rehabilitation training was conducted by a professional speech trainer. In acupuncture treatment, speech function area in scalp acupuncture, Jinjin (EX-HN 12) and Yuye (EX-HN 13) in tongue acupuncture and Lianquan (CV 23) were the basic points. The supplementary points were selected according to syndrome differentiation. Bloodletting method was used in combination with acupuncture. Psychotherapy was applied by the physician in psychiatric department of the hospital. The corresponding programs were used in each group. Examination of Aphasia of Chinese of Beijing Hospital was adopted to observe the oral speech expression, listening comprehension and reading and writing ability.

RESULTSAfter 21-day treatment, the total effective rate was 92.5% (37/40) in observation group 1, 97.5% (39/40) in observation group 2 and 87.5% (35/40) in control group. The efficacies were similar in comparison among 3 groups. The remarkable effective rate was 15.0% (6/40) in observation group 1, 50.0% (20/40) in observation group 2 and 2.5% (1/40) in control group. The result in observation group 2 was superior to the other two groups (P<0.01, P<0.001). In comparison of the improvements of oral expression, listening comprehension, reading and writing ability, all of the 3 groups had achieved the improvements to different extents after treatment (P<0.01, P<0.001). The results in observation group 2 were better than those in observation group 1 and control group.

CONCLUSIONAcupuncture and psychological intervention combined with rehabilitation training is obviously advantageous in the treatment of post-stroke speech disorder.

To identify HLA novel allele in Chinese Han individuals, an unknown HLA-A allele was detected by PCR-SSP and FLOW-SSO in Chinese Han individuals. Heterozygous sequence-based typing (SBT) showed that there were 3 differences compared with database in exon 2. Its anomalous patterns suggested the possible presence of either a novel A * 30 or a novel A * 24. To separate the two alleles and to determine whether the allele is novel, the HLA-A * 30 and HLA-A * 24 alleles were amplified separately by using a commercial kit for the single allele-specific sequencing strategy, and both alleles for exons 2 - 4 were sequenced according to the manufacturer' protocol. To prepare B-lymphoblastoid cell line of the novel HLA allele by using Epstein-Barr virus-infected B-lymphoblastoid cells in the peripheral blood. The results indicated that the sequencing results showed HLA-A alleles of the sample to be HLA-A * 240201 and a new A * 30 allele. The sequences of the new A*30 were identical to those of HLA-A * 300101 except for three nucleotide changes in exon 2: at nt 121 (A-->C), nt 123 (T-->C) and nt 126 (A-->G), resulting in an amino acid residue substitution from S (AGT) to R (CGC) at codon 17 and a synonymous substitution from G (GGA) to G (GGG) at codon 18. Immortalized B-lymphoblastoid cell line of the novel HLA-A * 3018 allele was achieved, the sequence of HLA-A * 3018 allele was submitted to GenBank and its accession number was DQ872509. In conclusion, the HLA-A * 3018 is a novel HLA-A allele and has been officially named HLA-A * 3018 by the WHO Nomenclature committee in August 2006 (HWS10004039).

OBJECTIVETo describe the characteristics of child pedestrian traffic injuries among aged 0-14 years old in Guangzhou city and to provide information on road, vehicle and human injuries in pedestrian.

METHODSA database of all motor vehicle crashes involving child pedestrian traffic injury cases over a five-year period (2000-2004), was from the police department.

RESULTSThe annual pedestrian traffic injury rates on incidence, mortality and case fatality were 17.63/ 1,100,000, 1.78/ 100,000 and 10.07% respectively. Both incidence rate and mortality peaked in the 5-9 age group were 26.80/ 100,000 and 2.57/ 100,000, with case fatality peaked in the 0-4 age group (13.29%). For males, the incidence (20.98/ 100,000) and mortality (2.00/ 100,000) were higher than that in females (13.83/ 100,000, and 1.52/ 100,000). The main injured parts of body would include multi-areas (40.34%), head (26.75%) and lower limbs (21.53%). 10.07% of the cases died and 66.18% and 23.75% of them having had severe and slight injures. The major causes were due to drivers (57.50%) and pedestrians (33.47%) faults with top three responsible vehicles were cars (40.14%), two-wheeled motorcycles (34.38%) and vans (22.15%).

CONCLUSIONData from pediatric pedestrian injury poses a threat to children and adolescents, data suggesting that it is important to change behaviors of both drivers and pedestrians.
