Objective To study the feasibility of endoscopic thyroidectomy with bipolar electrocoagulation. Methods Endoscopic partial thyroidectomy via precordial approach, mainly by using bipolar electrocoagulation and scissors, was accomplished in 21 patients with thyroid tumors with a diameter of 0.7～5.5 cm. Results The operation was accomplished endoscopically in 20 patients, whereas a conversion to open thyroidectomy was conducted in 1 patient. The mean incision length was 22 mm, the operation time was 69?47 min, and the blood loss was 55?41 ml. Postoperative analgesic treatment was required in 2 patients and no serious complications happened. Conclusions Endoscopic thyroidectomy with bipolar electrocoagulation is feasible in the absence of ultrasonic scalpel.

Objective To evaluate the feasibility of hand-assisted laparoscopic colorectal resection. Methods Clinical data of 21 cases of hand-assisted laparoscopic colorectal resection in this hospital from October 2003 to August 2004 were retrospectively reviewed. Results The hand-assisted laparoscopic resection was accomplished in 20 cases. The mean operation time was 144 min, the mean blood loss was 120 ml, the mean number of dissected lymph nodes was 8.5, and the mean time to intestinal function recovery, 69 h. Postoperative abdominal bleeding was found in 1 case, which was cured with conservative therapy. A conversion to open surgery was needed in 1 case. Conclusions Hand-assisted laparoscopic colorectal resection safe, feasible, and radical, with advantages of fewer complications and simplicity of performance.

Objective Onto investigate the indoor quality control method for qualitatively detecting the laboratory indicators of TORCH infection (rubella virus IgG ,cytomegalovirus IgG and IgM ,toxoplasma IgG and IgM ) .Methods The statistical method , normal distribution data ,ratio and standard deviation of positive rate detected by the ELISA method were adopted ,1+2s was set as the out of control rules ,the semi Lerey‐Jennings quality control chart was drawn;the direct probability calculation method was a‐dopted for the non‐normal distribution data and small probability event .The testing data of 57 batches were retrospectively ana‐lyzed .Results The positive rate of rubella virus IgG was 86 .66% ,cytomegalovirus IgG/IgM positive rates were 98 .87% and 0 .13% ,toxoplasma gondii IgG/IgM positive rates were 2 .43% and 1 .71% ,the data of 151 ,3 ,5 ,176 ,27 samples had the critical value range of five indicators .The number of out of control was once for cytomegalovirus IgG ,once and 4 times for Toxoplasma gondii IgG/IgM .Conclusion The indoor quality control for the ELISA qualitative detection of TORCH infection can adopt the data of daily detection positive rate or negative rate for monitoring the false positive .The critical value range of specimens should be fur‐ther conducted the recheck or confirmation experiment .

To analyze the incidence,clinical manifestations and causes of 42 in patients with anaphylaxis from 1990 and follow its change before and after 2005 retrospectively.The mean age was (39 ± 16) years.The ratio of male and female was 1:2.2.The incidence increased obviously after 2005 (30 vs.12).A majority of patients were females after 2005 (24 vs.5).The proportions of patients with impaired nerve system,circulatory system and hypotension decreased after 2005 (P ＜ 0.01,P ＜ 0.05,P ＜ 0.01).Anaphylaxis attacked more often intra-operatively after 2005 (43.3 ％ vs.1 / 12).The most common cause was drug(35/42),especially antibiotics(14/35).

Objective To study the relationship between ultrasonography of arteria dorsalis pedis and Hemorheology in patient with diabetic foot.Methods According to with or without frank anabrosis,51 patients were devided into two sub-groups:anabrosis group (23 patients) and no-anabrosis group (28 patients).The correlativity was analysed between the parameters of ultrasonography in arteria dorsalis pedis and hemorheological indices on patients with diabetic foot.Results When compared to patients without ulcers,vascular inner diameter (D),peak systolic velocity (PSV),resistent index (RI) and pulsatility index (PI) on patients with frank anabrosis were decreased significantly,but whole blood viscosity at high shear rate (BVH),whole blood viscosity at low shear rate (BVL),plasma viscosity (PV),fibrinogen (Fib) were increased.Multiple regression analyses indicated that the relationship between BVH,BVL and D was presence,partial regression coefficient (r) was -0.004 and -0.009 ; the relationship between PSV and BVH,PV was intimate,r was -0.957 and -25.655 ; the relationship between RI and BVH,PI and BVH,PV,Fib were relatively intimate,r was -0.009 , -0.141 , -2.666 , -0.383 ,respectively.Conclusions The changes of hemorheology can aggravate the abnormality of hemodynamics and the degree of vascular lesion in small vessels of lower limb,so it is one of influencing factor leading to lower limb arterial ischaemia and diabetic foot deterioration.

OBJECTIVE: To establish a RP-HPLC method for the determination of the content of hesperidin in Yangweishu tablets.METHODS: The samples were separated on octadecyl silane bonded gel silica column(150 mm?4.6 mm,5 ?m) with the mobile phase consisted of methanol-7% acetic acid solution(32∶68) under a detection wavelength of 283nm.RESULTS: The linear range of hesperidin was 49.6～892.8 ng(r=0.999 9) with an average recovery rate of 99.02%(RSD=0.45%,n=9).CONCLUSION:The method is simple,accurate,reproducible and applicable for the quality control of Yangweishu tablets.

Objective To investigate the value of ultrasound examination in the diagnosis of acute appendicitis. Methods Emergency abdominal ultrasound examination was performed on 152 children who had clinically suspected acute appendicitis. Results Sixty-three children were diagnosed as acute appendicitis by ultrasound . Among them, fifty-nine children had emergency appendectomy; the other 4 had delayed appendectomy six months after conservative therapy for appendiceal mass. All of the diagnoses were confirmed to be correct by pathologis examination . Among the other 89 children, the diagnosis was luteinic rupture in 4, choledochal cyst in 2, omental cyst in 1, hydronephrosis in 1, and nephrolithiasis in 1. Eighty of them were diagnosed as mesenteric lymphadenitis and treated conservatively. Seventy-six of these eighty children recovered , and appendectomy was performed on four patients. In two of them the diagnosis was suppurative appendicitis, and in two, the diagnosis was simple appendicitis. Conclusions Combined with consideration of the symptoms and signs, ultrasound is valuable in the diagnosis of appendicitis.

AIM: To study the effects of dietary factor on liver gene expression profile in apoE~(-/-)/LDLR~(-/-)/Lepr~(db/db) mice and atherogenesis. METHODS: The gene expression profile was determined by using cDNA microarray. Total plasma TC and TG level were measured with COD-PAP and GPO-PAP methods respectively. The morphological characters of the aorta were also observed. RESULTS: Among the 4000 target genes, 78 and 114 genes were up-and down-regulated, respectively, in treble genes mutants fed with high fat high cholesterol diet compared with that of regular chow littermates, including lipid metabolism, carbohydrate, cell skeleton and immune related genes. Atherogenic diet induced severe plasma hyperlipidemia even in the early stage and also accelerated atherogenesis in the treble genes mutant mice. CONCLUSION: The data suggest that atherogenic diet aggravates abnormal plasma lipid metabolism and induces severe hyperlipidemia, and atherogenesis in the treble genes mutant mice as well.
