Objective To explore the protective effects of 10-HDA combined with AA-2G on UVA-induced photodamage in fibroblasts. Methods The primary cultured human skin fibroblasts were divided into three groups: blank control group, UVA irradiation group and 10-HDA+AA-2G group. The cell viability and cellular senescent state were analyzed using CCK-8 and senescence associated-β-galactosidase (SA-β-gal) staining, respectively. Fluorometric assays were performed to detect the formation of reactive oxygen species (ROS) in the cells. Results Compared with those in control group, the cell viability was decreased (P < 0.05), and the SA-β-gal positive cells and ROS level were significantly increased (P<0.01 for both) in UVA-irradiated group. Compared with those in UVA-irradiated group, the cell viability was significantly increased (P < 0.01), and the SA-β-gal positive cells and ROS level were significantly reduced (P < 0.05, P < 0.01, respectively) in the 10-HDA combined with AA-2G group. Conclusion Fibroblasts treated with 10-HDA and AA-2G are significantly protected from UVA-induced cytotoxicity, cellular senescence and ROS, indicating that 10-HDA combined with AA-2G has photoprotective effects. Therefore, 10-HDA combined with AA-2G may be a potential combination for the prevention and treatment of skin photoaging.

OBJECTIVETo investigate the therapeutic effect of alar rotation flap for severe alar retraction.
METHODSPatients with severely retracted alar underwent ala reconstruction using alar rotation flaps and autogenous cartilage batten grafts. First, costal cartilage was used to reshape the nasal tip and nasal dorsum. Then cartilage patch was used to extend and thicken the retracted alar. Then the alar rotation flap was transferred to correct retracted alar.
RESULTSFourteen patients with severe alar retraction underwent alar reconstruction with alar rotation flap and alar batten grafts. The alar retraction was corrected in all cases, with improvements functionally and aesthetically. No recurrence of alar retraction was noted. The incision healed with acceptable cosmetic results, with obvious scar in only one patient (one side).
CONCLUSIONSThe alar rotation flap is an effective and reliable surgical option to correct severe alar retraction. Scar can be kept inconspicuous by precise placement of the incision within the junction of the ala and the nasal dorsum, following principles of the aesthetic nasal subunits.

BACKGROUND: The angiotensin-converting enzyme (ACE) is the important component of the renin-angiotensin-aldosterone system (RAS). The ACE gene has, in fact,insertion/deletion polymorphism in intron 16, consisting of a 287-base pair Alu repeat sequence. ACE gene heterozygotes insertion/deletion (I/D) polymorphism is correlated with cardiovascular disease and IgA nephropathy and other diseases. OBJECTIVE: To investigate the distribution of ACE gene I/D polymor-phism in Chinese Han population in comparison with other known ethnic populations. DESIGN: Observation study on healthy individuals of Han nationality. SETTING: Key Laboratory of Clinical Immunology of Jiangsu Province; Department of Laboratory Medicine, First Hospital Affiliated to Soochow University; Department of aboratory Medicine, College of Medical Technology of Jiangsu University PARTICIPANTS: Totally 241 healthy individuals who received the healthy examination in the First Hospital of Soochow University between December 2005 and January 2006 were recruited in the experiment. They were 152 male and 89 female , with mean age of (27±8)years. All the participants without blood relationship were Han nationality from Suzhou region in China, free from disorder of hepatic, renal, endocrine and cardio- cerebrovascular diseases which were confirmed by clinical and experimen- tal examination. METHODS: Genotype of ACE gene I/D polymorphism allele of 241 healthy individuals of Han nationality was detected with polymerase chain reaction (PCR). PCR purified products with genotype of deletion/deletion (DD) and insertion/insertion (Ⅱ) polymorphism were performed DNA sequencing with fluorescence-labeled end termination method. MAIN OUTCOME MEASURES: Genotype and allele frequency of ACE gene I/D, as well as the comparison between them and those of other ethnic population. RESULTS: All the 241 subjects participated in final result analysis. ① The genotypes of ACE were DD, Ⅱ and ID. Compared with allele Ⅰ, allele D lost 287-base pair Alu repeat sequence. ②The frequencies of genotype Ⅱ, ID and DD were 46.1%, 41.5% and 12.4% respectively, with an allelic frequency of 66.8% for allele Ⅰ and 33.2% for allele D. ③The distribution of ACE genotype was similar between Japanese and Han nationality crowd, both presenting that type Ⅱ was commonly seen and type DD was the least; ID was mostly found in European and American crowd, but Ⅱ was little found. There was racial diversify of frequency of the distribution of ACE genotype among individuals of Han nationality and Japanese as well as Europeans and Americans. Compared with other nationalities, allele Ⅰ of individuals of Han nationality was significantly higher than that of above nationalities (χ2=105.55,P < 0.01), but allele D was obviously lower (χ2=87.54,P < 0.01). CONCLUSION: ACE gene polymorphism has racial diversify. To know genetic features of ACE gene polymorphism of individuals of different na tionalities is the basis and prerequisite to study the correlation of ACE gene I/D polymorphism with diseases.

Objective To analyze the clinical effect of nutritional support for postoperative patients with esophageal cancer with fat emulsion and amino acids (17) and glucose (11%) injection (Calvin injection). Methods A total of 68 patients with esophageal cancer treated in the chest surgery in our hospital from December 2014 to December 2016 were selected and randomly divided into two groups with 34 cases in each group. All patients were treated with surgery for esophageal cancer. The patients in the study group were treated with Calvin injection after operation while patients in the control group were treated with conventional fluid replacement therapy. Subjective comprehensive assessment (SGA) was used to assess the nutritional status of the patients and the weight, serum total protein (TSP), serum albumin (Alb), transferrin (TF) content, urea nitrogen content in on one week, malnutrition improvement and complications of the patients in two groups were recorded and compared. Results The weight of the patients with esophageal cancer in the two groups after operation was decreased, and the weight loss of the patients in the study group was lower than that of the control group and the difference was statistically significant (P<0.01). The decrease degree of TSP, Alb and TF in the study group was lower than that in the control group, and the difference was statistically significant (P<0.05). The negative nitrogen balance of the two groups was improved, and the improvement of the negative nitrogen balance in the study group was better than that in the control group, and the difference was statistically significant (P<0.01). The postoperative malnutrition in the patients with esophageal cancer was improved. The improvement degree of malnutrition in the study group was better than that in the control group, and the difference was statistically significant (P<0.05). The incidence of complications in the study group was lower than that in the control group, and the difference was statistically significant (P<0.05). Conclusion Compared with the traditional method of postoperative fluid replacement, Calvin injection can improve the recovery of the body function of the patients with esophageal cancer after operation, improve the patient's negative nitrogen balance and nutritional status, reduce the incidence of complications, and improve the clinical prognosis. This treatment is safer and more effective and it is worth popularizing in clinical practice.
