Objective To investigate the difference between the self-evaluation of patients with dental and facial esthetics in skeletal malocclusion and normal persons.Methods The subjects were divided into three groups:62 patients with skeletal Class Ⅱ,84 patients with skeletal Class Ⅲ,as well as 130 persons in control group.There was no obvious difference in gender and age among the three groups.Happiness with dental and facial appearance was assessed using questionnaires.Analysis of variance,linear regression and logistic regression were used for statistical analysis.Results Skeletal malocclusion patients were less happy with their dental appearance than control group.Class Ⅱ patients and women had lower happiness scores for their dental appearance.Among skeletal malocclusion patients,the shape (44.5 ％) and prominence of their teeth (17.8 ％) were the most frequent causes of concern.Older subjects,women,and skeletal malocclusion patients were less happy with their facial appearance.Most of them were dissatisfied with the facial appearance focused on the chin (53 ％),facial contours (37 ％),and the position of the teeth when smiling (33 ％).A greater proportion of Class Ⅲ subjects than Class Ⅱ subjects wished to change their appearance.Conclusions The findings indicate that women and skeletal malocclusion patients have lower levels of happiness with their dentofacial appearance.Although Class Ⅱ patients exhibit the lowest levels of happiness with their dental appearance,there is some evidence that concerns and awareness about their facial profile are more pronounced among the Class Ⅲ patients.

[Method] FromLanshi Micang-Anal Fistulaof eight prescriptions for treatment of hemorrhoids and analysis, on the basis of combining the characteristics of compatibility with tumors inDongyuan effect testand the specific prescription, made analysis of anal fistula, diagnosis and treatment of anal fistula for the study of LI Dongyuan thought. [Results] LI Dongyuan from dampness, heat, wind, dryness four on the treatment of anal fistula, with angelica, Gentiana and blood dryness of medicine, to Shufeng pain, Xinrun and blood on regulation of syndrome treatment, paid attention to diet to restore the anal fistula. [Conclusion] LI DongyuanLanshi Micangis rich in content, the treatment of anal fistula has experience, as of today, the diagnosis and treatment on anorectal diseases of clinical thought still has important guiding significance.

Objective To explore the effect of oxymatrine o n the airway inflammation and the cytokine production in asthmatic mice. Methods Forty BALB/c mice were divided into four groups in cluding a control group (group A), an asthmatic model group (group B), a dexamet hasone treatment group (group C) and a oxymatrine treatment group (group D). Ast hma mouse models in group B, group C and group D were prepared by injecting oval bumin (OVA) into the abdominal cavity and inhalation of aerosol. Group C were in jected dexamethasone, and group D recceived oxymatrine on day 15 to 22 .The numb er of EOS and the concentration of IL-4 and IL-5 and IFN-? in th e mouse bronchoalveolar lavage fluids (BALF) were detected. Results Oxymatrine could significantly reduce the mumber of EOS and the concentration of IL-4 and IL-5, and increase the level of IFN-? in the BALF of asthmatic mice. Significant difference was fo und between group D and group A or B(P0.05). Conclusion Oxymatrine can remarkably reduce the mumber of i nflammation cells in the BALF, and influence the level of cytokines so as to imp rove airway inflammation in the patients with asthma.

Objective To explore the feasibility and safety of laparoscopic total colectomy for familial adenomatous polyposis. Methods All 9 patients with familial adenomatous polyposis received laparoscopic total colectomy were analyzed. Results Laparoscopic total colecto-my was successfully performed in all the 9 patients. The operative time,blood loss,flatus and hospitalization were respectively 230~310 min, 80~210 mL,2~3 days and 12~14 days. All patients were followed up for 6~36 months. The postoperative recovery was good. Conclusion Total colectomy can be successfully perfomed with laparoscopic assisted in treating familial adenomatous poliposis. It is a feasible and safe surgical procedure and can significantly improve the quality life.

Objective To development a cooling crystallization process that is suitable for industrial preparation of purified dihydromyricetin.Methods Screen design was used to investigate effects of process parameters such as,temperature,concentration ethanol aqueous,quantity of activated charcoal and adsorption time on yield and purity of dihydromyricetin.Purity was verified by high performance liquid chromatography and thin layer chromatography.The solubility of dihydromyricetin in water at viable temperature and ethanol proportion was also determined by UV spectrophotometry.The solid form was characterized by thermal analysis and powder X-ray diffractometry.Results When temperature was ＞ 85 ℃,ethanol concentration ＜ 10％,dosage of activated charcoal 0.1％-0.3％,and adsorption time 1-3 min,yield of dihydromyricetin was more than 70％,and the purity greater than 98％.The crystals,prepared by cooling crystallization from water and ethanol aqueous,had the same physical form and crystal habit.Conclusion Cooling crystallization from low concentration of ethanol aqueous gets higher yield and the process is more robust than crystallization from water.

Diffuse large B-cell lymphoma (DLBCL) is characterized by heterogeneity with respect to morphology, immune phenotype, molecular pathogenesis, clinical presentation and prognosis. With the development of genome and transcriptome sequencing, DLBCL was classified as four subtypes (EZB, BN2, MCD, and N1) or five subtypes (C1-C5). The new molecular pathological typing has a deeper understanding of DLBCL from the levels of genes and molecules which makes the judgment of prognosis more accurate and specific, and it is conducive to the clinical screening of more accurate targeted therapy.

AIM:To investigate the effects of Zhouluotong (Radix Astragali, Ramulus Cinnamomi, Radix Angelicae Sinensis, Radix Rchmannia, Herba Asari, etc.) on nerve function and polyol pathway in streptozotocin diabetic rats. METHODS: Streptozotocin diabetic rats were administrated with Zhouluotong for 8 weeks. Effects of drugs on sciatic never morphological alterations, sciatic never conduction velocity, aldose reductase activity, Na +,K + ATPase activity and sciatic nerve polyol contents were determined. RESULTS: Compared with diabetic group, sciatic never morphological alterations was improved, sciatic never conduction velocity was increased, aldose reductase activity was depressed and Na +,K + ATPase activity was increased in each administrated group. Sorbitol and gloucose contents were decreased in Zhouluotong groups. CONCLUSION: Zhouluotong could improve metabolism and function of peripheral nerve issue in streptozotocin diabetic rats. As a result of that, it could prevent diabetic peripheral neuropathy in streptozotocin diabetic rats.

OsRacD is a critical molecular switch involved in photoperiod fertility conversion of photoperiod sensitive genic male sterile rice.Taking OsRacD as bait,a new rice myosin heavy chain partial cDNA was isolated from the rice panicle by yeast two-hybrid,and designated OsMY1.The interaction between OsMY1 and OsRacD had been testified by yeast two-hybrid and pull down assay,it showed that OsMY1 could bind with OsRacD,suggested that OsMY1 maybe the target of OsRacD.The important evidence for further study on the functional relationship between OsMY1 and OsRacD in vivo are also provided.

Objective To observe the influence of ATP protection after brachial plexus injuries. Methods A total of 80 female Wistar rats,weighting 280～300 g,were randomly divided into ATP and con- trol groups.The right C_5～T_1 nerve roots were transected and then the intraperitoneal injection of 4m[ of ATP or normal saline was given immediately and once daily to the rats,respectively.The rats were sacrificed on postoperative days 14,28 and 42 respectively.The C_5-T_1 segments of the spinal cord were harvested.NT-3 activity was measured by enzymo-histochemistry method.Four weeks and 6 weeks postoperatively,ultrastruc- ture of the denervated skeletal muscles was observed.Results Compared to the control group,the expres- sions of NT-3 was increased in the treated groups with ATP injection (P
