ObjectiveTo evaluate the feasibility of endoscopic thyroid adenoma excision. Methods Dogs were used to practice endoscopic thyroid surgery under anesthesia. On the basis of animal experiment, endoscopic technique was introduced into dissection of follicular nodule of the thyroid lobe. One male and 11 females, aging between 23～52, underwent endoscopic enucleation of thyroid tumors from March 2002 to October 2002. Results The procedure was successful in 11 cases with 1 case converted to open surgery. The average time of operation was 70*!min, and intraoperative blood loss was 5～20*!ml. The patients had minimal pain. The cosmetic result was excellent. The incisions were completely hidden even with open necked skirt. Conclusions The cosmetic result of endoscopic thyroidectomy is satisfactory.

Objective To evaluate the feasibility and effect of the treatment of hematopathy by laparoscopy plus small incision splenectomy. Methods Dissection and separation of the ligaments of the spleen with laparoscopy first. And then made a small abdominal incision to ligate and divid the pedicle of spleen to finish splenectomy. Sixteen cases of idiopathic thrombocytopenic purpura(ITP) and 4 cases of heriditary spherocytosis(HS), who were treated by medication but no effect or recurrence, were treated by this procedure. Results All the patients recovered smoothly without infection of the wound ,without fluid collection in the spleen fossa,and without great intraoperative blood loss.The operating time was 1.5～2.5h(average 2.2h), intraoperative blood loss was 30～85ml(average 65ml).Hospital stay was 4～7d( average 6d). No recurrence was found during the follow-up for 0.5 to 2.5 years in this series. Conclusions Laparoscopy plus small incision splenectomy in the treatment of some hematopathy has many advantages,such as less trauma, safety, effective and quick recovery.

Objective To observe whether recent sexual intercourse might cause microscopic hematuria, and investigate the cause of hematuria. Methods Eighty healthy volunteers (40 men and 40 women) consented to have intercourse with their married couples and provide samples of urine for testing before intercourse and the first day morning, noon, evening and the second day morning after intercourse. After appropriate instruction, volunteers tested their own urine for the presence of blood using standard dipsticks. Any volunteer with hematuria after intercourse was offered a comprehensive hematuria assessment and followed-up for two years. Results None of the volunteers had positive hematuria before sexual intercourse. 9 of the 40 women, but no men, had positive hematuria at the first day morning after intercourse, and 3 of the nine patients with hematuria still had positive hematuria at the noon of the first day. Five women of 9 patients with hematuria accepted two years follow-up and no abnormal was identified. Conclusion It suggested that recent sexual intercourse was a cause of asymptomatic microscopic hematuria in women, and a history of recent sexual intercourse should be considered when assessing the clinical significance of microscopic hematuria in women.

Objective To investigate the effect of purified haemadipsa yanyuanensis injection on promoting intracerebral hematoma in rats and its possible mechanism.Methods We set up the experimental intracerebral hemorrhage (ICH) model in rats by stereotaxically injecting quantitative collagenase into their left caudate nucleuses.The effects of haemadipsa yanyuannesis injection on hematoma volume,neurological function recovery,brain water content(BWC),as well as histopathological changes were observed. BWC was calculated by weighing method,local capillaries were observed by micrangium perfusion.Results The intracerebral hematoma of the rats was reduced significantly( P

Objective To observe the effect and safety of buflomedil hydrochloride injection to intra cerebral hemorrhage in rats. Methods We established the experimental intracerebral hemorrhage (ICH) model in rats by stereotactic injecting quantitative collagenase into their left caudate nucleuses.The effects of buflomedil hydrochloride injection on hematoma volume,the score of neurological function deficit signs, as well as histopathological changes were observed. Local capillaries were observed by micrangium perfusion.Results 5 days after buflomedil hydrochloride injection might alleviate Wister rats' neurological function deficit signs, 86% rats from Grade Ⅲ to Grade Ⅰ, 14% rats from Grade Ⅲ to Grade 0( P

Objective To study the effects of hirudo extract liquor(HEL) on the expressions of HSP70 and TGF?-1 in intracerebral perihematoma tissues of rats.Methods We established the experimental ICH models in Wistar rats by stereotaxical injecting quantitative collagenase(0.7 U collagenaseⅦ) into their left caudate nuclei.The rats continued to be treated with HEL(treatment group) or normal saline(control group) through intravenous injection by vena caudalis and the scores of neurologic impairment in two groups were evaluated every day.The slices of these samples at 3rd,6th and 10th day were stained by immunohistochemistry and the positive cells of HSP70 and TGF?-1 were counted by image analysis system,respectively.Results The scores of neurologic impairment in two groups were remarkably reduced with time going((P

ObjectiveTo evaluate the influence of laparoscopic operation on pH value, phagocytic function of neutrophil, immunoadhesion activity of RBC CR 1 (complement receptor typeⅠ) in abdominal cavity. Methods Determination of the pH value, phagocytic function of neutrophil, immunoadhesion of RBC CR 1 in abdominal exudatives during laparoscopic procedures was undertaken and results were compared with the relative indexes detected in peripheral vein blood. Results The average pH value was 7.41, the percentage of the phagocyte was 74.6%, phagocytic index 55.7, and immunoadhesion activity of RBC CR 1 was 58% in blood during laparoscopic operation. While the average pH value was 7.14, the percentage of the phagocyte 65.6%, phagocytic index 47.6,and immunoadhesion activity of RBC CR 1 50% in the abdominal exudatives. Conclusion Compared with the peripheral vein blood indexes, the intraabdominal pH value, phagocytic function of neutrophil and immunoadhesion activity of RBC CR 1 decreased significantly during laparoscopic operation. The intraabdominal inflammation may diffuse with the effect of CO 2 pneumoperitoneum when patients with serious inflammation receive laparoscopic operation.
