We made studies on historical records on Li Jun and the features and contents of this book, and proved that Symptomatic Figures of Lip and Tongue was not written by him, but a Chinese medical book written by Japanese.

Objective To evaluate the effects of ethyl gallate (EG ) on sepsis-induced acute lung injury (ALI) in rats .Methods Forty-eight healthy male Wistar rats ,aged 10-12 weeks ,weighing 150-250 g ,were randomly divided into 3 groups (n=16 each) using a random number table :control group (group C) ,group ALI , and group EG .The animals were anesthetized with intraperitoneal pentobarbital sodium 50 mg/kg .Sepsis was induced by cecal ligation and puncture (CLP) .EG 1 ml/h (50 mg·kg-1 ·h-1 ) was infused intravenously via the femoral vein for 4 h starting from 6 h after CLP in group EG .The equal volume of normal saline was given instead in group ALI . The rats were sacrificed at 10 and 24 h after CLP (T1 ,2 ) , and the lungs were removed for determination of wet/dry lung weight ratio (W/D ratio ) , superoxide dismutase (SOD ) activity , contents of malondialdehyde (MDA ) and glutathione (GSH ) , and 3-NT expression (by immuno-histochemistry ) in lung tissues .The pathological changes of the lung were examined with light microscope .Results Compared with group C ,the W/D ratio ,MDA content and 3-NT expression were significantly increased and GSH content was decreased at T1 ,2 ,the SOD activity was significantly decreased at T2 in group ALI ,and the MDA content and 3-NT expression were increased at T1 ,and the W/D ratio ,MDA content and 3-NT expression were increased and GSH content was decreased at T2 in group EG ( P<0.05) .Compared with group ALI ,the MDA content was significantly decreased at T1 ,and the W/D ratio ,MDA content and 3-NT expression were decreased ,and GSH content and SOD activity were increased at T2 in group EG ( P<0.05) .The pathological changes of the lung were obvious in group ALI , and significantly attenuated in group EG .Conclusion EG can attenuate sepsis-induced ALI by antioxidative effects in rats .

Objective To explore the effect of diammonium glycyrrhizinate(DG) and astragalus membranaceus (AM) injection on the clinical comprehensive score in patients with acute lung injury (ALI). Methods According to the random number table method,a prospective random controlled study was conducted in which 60 cases of patients with ALI were divided into a study group and a control group(each,30 cases). Both groups received a comprehensive treatment based on the new guidelines,and the study group was additionally given DG and AM injection(DG 150 mg+AM 20 ml)one time per day for 7 days. The scores of lung injury,acute physiology and chronic health evaluationⅡ(APACHEⅡ)and systemic inflammatory response syndrome(SIRS)were measured at baseline,3rd and 7th day after treatment,and ventilation support time and final disease mortality rate were also calculated in all the patients. Results There were no statistically significant differences between the two groups in the scores of lung injury,APACHEⅡand SIRS before treatment and after treatment for 3 days(all P>0.05),with prolonged treatment,the above indexes were significantly reduced compared with those before treatment in the two groups,and the decreases in scores of indexes in study group was more significant than those in control group after treatment(lung injury score:1.31±0.99 vs. 2.29±1.08,APACHEⅡscore:18.43±8.17 vs. 24.23±6.98,SIRS score:1.69±0.89 vs. 2.60±1.04,all P<0.01). The time(hour)for ventilator support in study group was shorter than that in the control group(176.10±57.81 vs. 286.07 ± 156.27,P<0.01),but there was no statistically significant difference in mortality rate between the two groups(13.33%vs.16.67%,P>0.05). Conclusion The results suggest that DG and AM injection improve the scores of lung injury,APACHEⅡand SIRS,and alleviate the lung injury,so that the injection is beneficial to the early weaning from the ventilator to support treatment in patients with acute lung injury,and has certain therapeutic effect on ALI.

Objective To explore the effect of ginseng co?enzyme Q10 suncream on the skin damage caused by ul?traviolet ( UV) radiation in mice. Methods 36 mice were randomly assigned to four groups. The mice were shaved on the back and the left untreated side was taken as control group, or was treated with UV as model group. Before treated with UV, the mice were painted with suncream containing ginseng co?enzyme Q10 , or octyl methoxycinnamate as positive con?trols. The mice were treated for 8 weeks. At the end of the experiment, blood samples of all mice were collected from the eyes, then subjected to cell counting or biochemical measurements, and skin samples were cut for pathological examina?tion. Results Compared with the control group, there was a significant increase in white blood cell counts ( P<0?05 ) and MDA content ( P<0?05 ) , and declined serum levels of SOD ( P <0?05 ) and GSH?Px ( P <0?05 ) in the model group, and the skin was rough and wrinkled with stratum corneum exfoliation. Compared with the model group, the mice of ginseng co?enzyme Q10 suncream group had significantly lower white blood cell count ( P<0?05 ) and MDA content ( P<0?05), and increased serum levels of T?SOD(P<0?05) and red blood cell counts (P<0?05). The skin had no rough? ness and wrinkles and without stratum corneum exfoliation. Compared with the model group, the positive control group showed significantly decreased white blood cell count (P<0?05) and MDA content (P<0?05), and increased serum lev?els of GSH?Px(P<0?05). The skin had no roughness and wrinkles and no stratum corneum exfoliation. However, there was no significant difference between the ginseng co?enzyme Q10 suncream group and positive control group. Conclusions Ginseng co?enzyme Q10 suncream shows satisfactory preventive effects on the UV radiation?induced skin damage in mice, similar to the preventive effects of the octyl methoxycinnamate?containing sunsream.

Objective To introduce a new spinal surgery navigation system based on structured light scanning(structured light navigation system,SLNS),and to compare accuracy of pedicle screw placement using SLNS,CT based navigation system and free hand technique.Methods Thirty-two calf vertebral pedicles,40 and 32 were placed with pedicle screws using SLNS,CT navigation system,and free hand technique,respectively.The pedicle breakage ratio,transverse section angle (TSA),sagittal section angle (SSA),screw offset deviation of each screw were detected according to CT images.Results The pedicle breakage ratio of pedicle screws in SLNS group,CT navigation group and free hand group were 6%(2./32),5%(2/40),25%(8/32),respectively.The difference between each of the two navigation groups and free hand group were statistically significant regarding frequency of screw misplacement.The difference between the two navigation systems was not obvious.The average SSA error and TSA error in SLNS group were 2.58°±2.74° and 4.26°±5.20°.For CT navigation group,they were 2.95°±2.61° and 3.13°±-2.75°.There was no statistical difference between the two navigation methods for the SSA or TSA error.There was no statistical difference in offset deviation among SLNS group,CT navigation group and free hand group.Conclusion The SLNS is a new and practical navigation system,which has similar accuracy with CT navigation system.

Objective To examine the causes of high frequency sensorineural hearing loss caused by piston technique of stapes surgery.Methods The retrospective analysis involved in thirty cases(49 ears)with stapedectomy from February 2004 to 2009 at our hospital.Pure tone audiometry was performed for each patient who underwent stapedectomy both during the two days preoperation and 1,3,6 months postoperation.Results One month after operation at 8000 Hz,the air conduction hearing threshold was 8 dB less than that before,4 000 Hz average bone conduction hearing threshold was 10 dB less than that before(P < 0.01).The average high-frequency hearingthreshold of ≥40 years old group was noticeably declined than that of 40 years old group(P < 0.01).There was no association between the tinnitus and high frequency hearing loss.(P >0.05).Conclusion Transient high-frequency sensorineural hearing losses occurred to most patients under going stapedectomy,but showed significant improvement,3 months after the surgery.The average high-frequency hearing threshold of ≥40 years old group was seriously declined than that of 40 years old group.

This study investigated the changes of CD4(+) CD25(+) regulatory T cells (Tregs) in peripheral blood of patients with hepatocellular carcinoma before and after transcatheter arterial chemoembolization (TACE). The proportion of CD4(+) CD25(+) Tregs among CD4(+) T lymphocytes in peripheral blood of 33 patients with hepatocellular carcinoma was determined by flow cytometry before, 1 week and 1 month after TACE. And 25 healthy volunteers served as control. One month after TACE, the patients were divided into two groups: 22 in group A, who were in stable condition or getting better; and 10 in group B, who were deteriorating. One patient died and was excluded. The results showed that the percentage of CD4(+)CD25(+) Tregs among CD4(+) T lymphocytes did not significantly change in the 33 patients 1 week after TACE as compared with that before TACE, however, the difference was significant (P<0.01) between the patients with hepatocellular carcinoma and the healthy subjects. The percentage of CD4(+) CD25(+) Tregs among CD4(+) T lymphocytes in group A 1 month after TACE was decreased significantly in comparison with that before and 1 week after TACE (P<0.01), whereas, that in group B was increased significantly 1 month after TACE (P<0.01). It was concluded that patients with hepatocellular carcinoma had a higher proportion of CD4(+)CD25(+) Tregs in peripheral blood. TACE did not significantly affect the level of CD4(+) CD25(+) Tregs within short time (such as 1 week). The proportion of CD4(+)CD25(+) Tregs in peripheral blood 1 month after TACE was related to the prognosis of hepatocellular carcinoma.

Objective To investigate the regularity and predictors of weight loss during concurrent chemo-radiotherapy for nasopharyngeal carcinoma patients. Methods A retrospective study was carried out on 82 patients with nasopharyngeal carcinoma ,with average age of 45 years ,who received concurrent chemoradiotherapy at the Affiliated Cancer Hospital of Guangzhou Medical University. Paired t-test was used to analyze the weight loss pattern during chemoradiotherapy. The Spearman′s rank correlation analysis was used to investigate the correlation between high weight loss(HWL)and the clinical factors. Results The paired t-test showed that the weight of the patients decreased continuously every week during chemoradiotherapy(P < 0.05),and the value dropped most significantly during the 4th week. Among these 82 patients,32 were determined as HWL(weight loss > 10%). Spearman′s rank correlation analysis showed that HWL was associated with older age,female,higher T and TNM stage,3D-CRT technology,the higher dose of radiotherapy in nasopharynx and in neck lymph node,and decreases of leukopenia and hemoglobin over degree Ⅱ(P<0.05). Conlousions Weight may decrease continuously every week during chemoradiotherapy for nasopharyngeal carcinoma patients. Age,gender,T stage,TNM stage,radio-therapy dose,and leukopenia and hemoglobin decreases may be predictors for weight loss degree during concurrent chemoradiotherapy for nasopharyngeal carcinoma patients.

OBJECTIVETo investigate whether the growth hormone gene (GH) promotor polymorphism (rs2854184) is associated with the occurrence or curve severity of adolescent idiopathic scoliosis (AIS).

METHODSTwo hundred and sixty-five AIS patients and 193 normal controls were recruited. The maximum Cobb angles were recorded in AIS patients. PCR-RFLP was used for the genotyping.

RESULTSThe genotype frequency distribution were AA 38.3%, AT 50.3%, TT 11.4% in AIS patients and AA 39.6%, AT 50.2%, 10.1% TT in controls for the promotor polymorphism rs2854184 in GH gene. It was comparable between AIS and normal control. The allele frequency distribution was also comparable between AIS and normal control. It was 63.5% for allele A, 36.5% for allele T in AIS patients and 64.7% for allele A, 35.3% for allele T in normal control. The mean maximum Cobb angle in AIS patients with AA, AT, TT genotypes were 33.8 degrees +/- 10.0 degrees, 36.4 degrees +/- 15.0 degrees, 34.5 degrees +/- 9.1 degrees, respectively, it was similar with each other.

CONCLUSIONThe GH gene promoter polymorphism is neither associated with the occurrence nor the curve severity of AIS.
