Objective To discuss the method of raising the rate of cut healing by first intention with electrized copper needles and removal of the angioma.Methods Analysis of the clinical history of 68 cases of angiomatous therapy by using the method of electrized copper needles and removal, and the investigation of the connection between the therapy method and the cut healing.Results The healing rate of the cut by first intention is 100% in the total resection of tumor, each 33.33% in the partial resection of tumor and the resection under skin flap, 0% in the resection of tumor and the skin grafting on the surface of wound. When the voltage controlled at 6V is compared with others, remarkably there is the difference (P

Objective: To evaluate an innovative surgical approach for submandibular gland resection with minimal invasive incision. Methods:With cutaneous incision of 30 mm in the submandibular area, six patients with chronic sialadenitis of submandibular gland were treated with this approach. Anterior facial vein and facial artery were maintained without ligation. Results:The operation time is ranged from 40 to 80 minutes. There were no facial nerve injuries. Furthermore, the surgical stigmata was minimized. Conclusion:The modified minimal incision for submandibular gland resection has less wound and better cosmesis.

Objective:Study on the possibility that human follicular dendritic cells(FDC) can increase HIV infection and to investigate the related mechanisms.Methods:Human FDC was isolated from tonsils and cultured with infected heterogenous pheripheral lymphocytes or cultured with infected hemogenous tonsilar T lymphocytes.HIV P24 antigen,HIV 1 env DNA and HIV 1 nef RNA were determined respectively with ELISA method,PCR or RT PCR method.Results:FDCs were cultured with infected heterogenous lymphocytes,the P24 antigen is 6 7 times higher than the control group(P

Objective To study the clinical pathological significance and relationship of placental glutathione-s-transferase(GST-?) and p53 protein expression in the tissues of human lung carcinomas. Methods The expressions of GST-? and p53 in 60 cases of lung carcinomas were detected by the LSAB immunohistochemical method. Results The positive rates of GST-? and p53 protein expression in lung carcinomas were 56 67% and 31 67% respectively. The expressions of both GST-? and p53 had obvious relationship with the differential degree of the tumors(P

Objective To discuss the illness mechanism and the reason of defective energy of the stomach and intestines with acute panereatitis.Method 43 cases of acute pancreatitis was studied which had the stomach and intestinal insufficiency to determine lesion degree of the stomach and intestines acording to the change of abdomen signs.Results The data found that the patient of light acute pancreatitis had light abdominal distention,cirumscribed abdominal tenderness and rebounding pain,weaken gurgling sound;most advanced acute pancreatitis had severe abdominal distention,abdominal tenderness and rebounding pain,almost no gurgling sound.Conclusion Abdominal sign could be a indicator to determine patient's condition of acute pancreatitis and a standard to diagnose acute pancreatitis.

Objective By detecting microsatellite instability(MSI) and loss of heterozygosity(LOH) in FHIT gene in sputum specimen,we intended to evaluate the sensitivity of FHIT gene detection to early diagnosis of lung cancer and explore effective method to screen lung cancer.Methods Based on liquid-based cytology,we collected and isolated sputum specimens in high risk group,abstracted DNA,and detected MSI and LOH in FHIT gene.Results The positive rate of MSI or LOH at single locus was between 41.6% and 49.5%;the site D3S1300 was the highest and it was 49.5%.At least 1 site out of 3 sites that had abnormal microsatellite accounted for 72.3% in lung cancer patients,two sites that appeared to change accounted for 45.5%,which was significantly different compared to non-lung cancer patients(P

Objective To evaluate the in vivo behaviour of the pulsed tablet in six scintigraphic studies.Methods The lag time and the anatomical position at the time of release were detected by scintigraphic evaluation.Results The different types pulsed release tablets all can achieve the lag time in vivo.Conclusion Scintigraphic study is the first considered method to evaluate the in vivo behaviour of the new formulation.

The article analyzed the phenomenon of changing names of Chinese medical journal in recent years,together with the influence of this changing,and put forward some relative management measures.

Hydroxypropyl-chitosan with substitution degree of 0.56 is prepared by the reaction of chitosan and epoxypropane by controlling condition. The water solubility of modified hydroxypropyl-chitosan is enhanced. When suitable concentration of hydroxypropyl-chitosan water solution responds to certain concentration of sodium polyphosphate based on ion gel method, the hydroxypropyl-chitosan nano-spheres with particle size of 500-700nm are obtained. Transmission electron micrograph shows that the shape of prepared hydroxypropyl-chitosan nano-sphere is uniform.

Objective To learn the academic level and scientific impact of the Chinese Journal of Dermatology by using bihliometric methods. Methods Citation frequencies, first authors and their affiliation, citing journals of cited articles published in the Chinese Journal of Dermatology from 2002 to 2007 were statistically analyzed according to the database of Chinese Medical Citation Index (CMCI) by using bibliometric methods. Results From 2002 to 2007, a total of 2259 original papers were published in the Chinese Journal of Dermatology. Of them, 1224 were cited with a total citation frequency of 3963, citation rate of 54.1%, average citation frequency per paper of 3.2 and top citation frequency of 204. The number of first authors of cited papers amounted to 893, and 61 (6.63%) authors published 3 or more cited papers during this period. These authors were distributed in 30 provinces, municipalities, autonomous regions and 1 foreign country; Jiangsu, Beijing, Zhejiang, Guangdong, Shanghai and Shandong ranked in the top 6 regions with high total citation frequencies. There were 517 journals citing articles published in the Chinese Journal of Dermatology from 2002 to 2007;the top citing frequencies were observed in the Chinese Journal of Dermatology, China Journal of Leprosy and Skin Diseases, The Chinese Journal of Dermatovenereology, Journal of Clinical Dermatology and Southern China Journal of Dermato-Venereology, etc. Conclusions The articles in the Chinese Journal of Dermatology have a high academic quality and citation frequency. Chinese Journal of Dermatology is an important publication in the dermato- venereology field as well as a core periodical in medical field of China.
