Objective:To study the teeth of the ancients in Xia Dynasty,the first dynasty in Chinese history about 4 000 years ago,and acquaint ourselves with their incidences of periodontal disease,and the evolution of oral diseases.Methods:The teeth and jaws excavated in Erlitoou,Henan Province and Youyao,Shanxi Province were observed with clinical methods.The specimens totaled 56 individuals(male 38,and female 18),including 894 teeth,and 86 dental arches.The objects were all permanent teeth.The major observation items were periodontal disease.The prevalence of periodontal disease of the people in Chinese Xia Dynasty were outlined.Results:The prevalence rate of periodontal disease was 19.80% in the 894 teeth,while prevalence rate was about 42.86% among the individuals.The premortal tooth lossrate was 7.45% in the observed teeth.Conclusion:Periodontal disease is an aging-related disease without sex difference and commonly seen in the mandible,which is quite similar to the situation at present.The periodontal disease was the main reason for tooth loss in people of Xia Dynasty.

Objective To determine whether preoperative embolization is a valuable adjunct to surgical excision of hemangioblastoma. Methods Eleven cases of hemangioblastoma, involving 8 of cerebellum , 1 of medulla oblongata and 2 of spinal cord shown by CT, MR and DSA were embolized preoperatively. The feeding arteries were catheterized with microcatheter and devascularized with polyvinyl alchol particles. Results The blood supplies of the tumor in 6 cases were completely eliminated, and partial occlusion through embolization were undergone for the other 5 cases. Surgical operation was undergone 1-7 days later with all, the 11 tumors totally resected acompanied by minimal blood loss and shortening of the operation time. In addition, manipulation and removal of these embolized tumors were actually easier than expected. No complications occurred during the procedures of embolization and operation. Conclusions Preoperative embolization of hemangioblastoma is a useful and relatively safe to surgical complete resection of this hypervascular tumor with significant reduction of blood loss and operation time.

BACKGROUND:The Notch signaling pathway is evolutionarily highly conserved and mediated by cel-cel interactions, which is widely involved in cel differentiation, proliferation and apoptosis. This critical transduction system participates in coordinating various functions of vascular endothelial cels, thus playing a vital role in the formation and remodeling of vascular network. OBJECTIVE: To elucidate the components of Notch signaling pathway and its impact on angiogenesis. METHODS: A computer-based online search of PubMed and CBM databases was performed. High-quality articles related to mechanism of angiogenesis regulated by Notch signaling were included, and repetitive studies were excluded. RESULTS AND CONCLUSION:Totaly 31 literatures were selectively included in this review. Angiogenesis is a complicated and muti-stage biological event and has been delicately regulated. Notch signaling participates in the regulation of every stage of angiogenesis directly or indirectly via the crosstalk with vascular endothelial growth factor, BMP-SMAD signaling and extracelular matrix molecules. Furthermore, consistent output of Notch signaling is essential for maintaining the stability and integrity of adult vascular system. This review wil thoroughly clarify the latest progress on angiogenesis regulated by Notch signaling and provide theoretical basis and a potential target for designing therapeutic methods against vascular disease.

Objective To investigate the principles of diagnosis and treatment of postoperative intestinal obstruction.Methods The clinical datas of 89 cases of postoperative intestinal obstruction treated from 2001 to 2005 were analyzed retrospectively.Results All the 89 cases were cured without severe complications such as intestinal fistula and no death.The early postoperative inflammatory intestinal obstruction occurred in 2 cases.Recurrent intestinal obstruction occurred in 2 cases.Conclusions Intestinal obstruction can be caused by operation in abdomen.The diagnosis depends on the medical history,clinical manifestations,abdominal plain X-ray and computed tomography.Therapeutic procedure and operative opportunity play an important role in the treatment of postoperative intestinal obstruction.Non-operative approach should be the first choice for early postoperative inflammatory intestinal obstruction.Prompt surgery is clearly indicated and valuable for acute or being strangulative obstruction.Active operative treatment should be considered in recurrent chronic intestinal obstruction.

BACKGROUND: Without any external stimuli in natural environment, it is applicable to observe the infrared radiant track over human body surface that is in conformity basically with the running courses of ancient fourteen meridians.OBJECTIVE: To probe into the influence of electroacupuncture on infrared radiant track along meridian courses over human body surface.DESIGN: Self-controlled opening experiment.SETTING: Department of Meridian Research of Academy of Traditional Chinese Medicine in Fujian Province.PARTICIPANTS: The experiment was performed in Key Laboratory of Meridian Research of Fujian Province from January 2000 to December 2002. Totally 53 students from Department of Acupuncture and Massage of Fujian College of Chinese Medicine were observation, of which, 38 students were males, 15 students were females, aged varied from 19 to 23years.METHODS: The receptors exposed completely the body areas required and sat quietly for 20 to 30 minutes to adapt to the environmental temperature. In natural state, 6T67 infrared thermo tracer produced by Japanese San-Ei Company was used to observe 1 to 2 infrared radiant tracks in advance as the control before acupuncture (scanned once per second). Afterwards, acupuncture was done on Guangming (GB 37), Neiguan (PC 6) and Dazhui (GV 14). The stimulation was given by a pair of stainless filiform needles, 6.6 cm long. The frequency of effectric pulse was 2 Hz, and 0.2 ms in duration. The video record was taken once every 5 to 10 minutes during stimulation. After acupuncture, 1 to 2 infrared radiant tracks were scanned.MAIN OUTCOME MEASURES: Tracks of isothermal display and whole thermal display on infrared thermography.infrared radiant track along meridian courses over the human body surface high basic temperature, acupuncture decreased skin temperature on infrared radiant track along meridian courses over the human body surface in a part of subjects. The skin temperature of a part of subjects was decreased acupuncture increased skin temperature on infrared radiant track along though it did not great affect the skin temperature on infrared radiant track along meridian courses over the human body surface in a part of subjects,acupuncture induced infrared radiant track to be more continuous and human body surface, acupuncture stimulates the infrared radiant track displayed along the meridians over human body surface, too.CONCLUSION: Infrared radiant track along meridian courses over the human body surface is a kind of normal life phenomenon existed commonly among peoples. Acupuncture not only induces the infrared radiant track of the related meridian, but also alters the skin temperature of the displayed infrared radiant track along meridian courses and makes it become more continuous and regular. Changes in tissue temperature are relevant necessarily with altered energetic metabolism. It is suggested that infrared radiant track along meridian courses is closely contributed to functional regulation of the human body.

Objective To evaluate the efficacy of perioperative antibiotic prophylaxis for tension-free repair of inguinal hernia. Methods A randomized, prospective double-blind control trial was performed to evaluate the efficacy of perioperative antibiotic prophylaxis for tension-free mesh repair in 180 cases of inguinal hernia from March 2007 to March 2008. Intravenous cefuroxime ( 1.5 g ) was given immediately before the surgery in two groups followed by postoperative administration of cefuroxime 1.5 g twice a day for 3 days in test group compared with NS infusion in the control group. Postoperatively 16 patients (8. 89 per cent) could not be contacted at any point, giving a response rate of91. 11%. The total number of subjects for per- protocol (PP) analysis was 180, 84 cases in test group and 80 cases in control group. Results Complete data were available for 164 patients, 3 ( 1.83 per cent) developed surgical site infection (SSI) including 2 cases of surgical site infection in test group and 1 case of superficial incision surgical site infection in control group. The differences were not statistically significant. The time to follow up was 12 -29 months, the mean follow up time in test group was (15.6 ±2.2) months and (18 ±3)months in control group respectively. 93.33% patients in test group were followed up and 88. 89% patients in control group. There were not hernia recurrence and side effect of antibiotics reported in the two groups.Conclusions To prevent SSI, it is necessary to use preoperative antibiotics prophylaxis just one time for inguinal hernia repair.
