Objective To investigate the effect of left lateral segmentectomy combined with fiber choledochoscope for hepatobiliary calculus.Methods Eighty-seven patients with hepatobiliary calculus who underwent hepatectomy from December,1998 to December,2008 were reviewed retrospectively.Forty-six patients underwent the section of common bile duct to remove calculus combined with left lateral segmentectomy and fiber choledochoscope( Group A),41 patients underwent left hepatectomy and section of common bile duct to remove calculus( Group B).The postoperative stone residual rate,complications and long-term outcome were compared between the two groups.Results The postoperative stone residual rate of either group was zero.Intraoperative bleeding ( 401.1 ± 180.4ml) ,operative times ( 202.5 ±36.6 rmin) of group A were significantly lower than those of the group B (515.9 ± 200.6ml and 257.3 ± 42.9min) ( P ＜ 0.001 and 0.01,respectively) .Hospital stays of group A was lower than that of group B,but this is no statistical significance ( P ＞ 0.05 ) .The incidence of postoperative complications were similar in the two groups( 15.2% v.s.24.4% ,P ＞ 0.05 ).The effective rates of the two groups were similar (91.3 % VS 92.7 %,P ＞ 0.05 ).Conclusions The long-term and short-term outcome of left lateral segmentectomy combined with fiber choledochoscope for hepatobiliary calculus is similar to that of left hepatectomy ,and can successfully shorten the hospital stay and reduce the hospital fee.

Objective:To investigate the effects of nitric oxide(NO) and inducible nitric oxide synthase (iNOS) in the experimental abdominal aortic aneurysm (AAA) rat model.Methods:An intra-aortic elastase infusion model was used.Control rats received intra-aortic saline infusion.In the remaining groups,intra-aortic elastase infusion was used to induce aneurysm formation.These rats were treated with intraperitoneal injections of saline postoperatively(experimental group),aminoguanidine postoperatively(medicine group).Serum NO and aortic diameter were measured,Changes of histology,iNOS and MMP-9 were observed in the aortic wall.Results:Experimental group produced AAAs with significant production of iNOS,MMPs and serum NO compared with controls.In medicine group reduced aneurysm size and displayed suppression of MMPs expression,inflammatory infiltrates and serum NO production were detected.Conclusion:Expression of iNOS and MMP-9 are induced and serum NO levels are increased in experimental AAA,iNOS and NO production by iNOS play an important role with detrimental effects during experimental aneurysm development.

Objective To investigate the value of treadmill exercise test and dipyridamole electrocardiography stress test (DP T) in diagnosis of coronary heart diseases (CHD), with an attemp of developing a safe, effective and simple diagnostic method for patients intolerable to the exercise. Methods Fifty two male patients aged from 41 to 75 years, averaged 58.44?8.79 years and with suspected or confirmed CHD were recruited to perform the treadmill exercise test, DP T and coronary angiography, respectively, within one month. Results The sensitivity and specificity of the treadmill exercise test for diagnosing CHD were 100% and 78.95%, respectively, while those of DP T for diagnosing CHD were 79.31% and 65.22%, respectively.As corresponded to the number of sites of coronary artery lesions,the numbers of cases with positive results revealed were 0, 2, 10 and 17 by the treadmill exercise tests and 0, 6, 11 and 15 by DP T, respectively.Based on the criteria of DP T, the sensitivity and specificity symptom, the changes in electrocardiography (ECG) and the combination of the two, for diagnosing CHD were 72.41%, 65.22%; 65.52%, 82.61%;and 79.31%, 65.22%, respectively. Conclusion The sensitivity and specificity of the treadmill exercise test and the DP T in the diagnosis of CHD were similar. More positive cases were revealed in above mentioned tests as the sites and degree of coronary artery lesion increased. DP T was particularly suitable for helping diagnose CHD in patients intolerable to exercise.

Because of the particularity and the complexity of integrated management of food, government regulators must perform the whole process of quality control and trace to evaluate and judge the merits of food instead of only depending on product standards.Quality metrics is a new concept for the food industry, and can be regarded as the comprehensive evaluation and measurement for product quality and the standard for judging the quality of food products.Request for Quality Metrics Guidance for Industry was issued, which not only established a new model for the quality control of pharmaceutical industry, but also provided a new way of quality management for the inspection organization.By introducing the contents of Request for Quality Metrics Guidance for Industry issued by the US FDA, on the basis of summarization and thought, the quality management and evaluation of pharmaceutical industry was compared, and the feasibility and applicability of quality metrics management in inspection and testing field, especially in food testing field was evaluated.In this paper, the concept of quality metrics was extended to the level of food inspection laboratory management with hope to provide ideas for the future development of food quality management model.

Objective To detect the serum growth hormone(GH),insulin-like growth factor-I(IGF-Ⅰ),insulin-like growth factor binging protein-3(IGFBP-3) levels in children with hypothyroidism and explore the change regulation of GH-IGF axis and thyroxine.Methods Fifty-six hypothyroidism children were divided into congonital hypothyroidism(CH)(14 cases) and Hashimoto's thyroiditis(32 cases).Serum GH,IGF-Ⅰ,IGFBP-3 levels of 56 hypothyroidism children before and after luothyroxine sodium L-T4 treatment and 50 normal children were detected with radioimmunoassay or enzyme-linked immunosorbent assay methods.Results Serum IGF-I,IGFBP-3 levels in 9 CH newborn group were lower,and they were normal after thyroxine substitute therapy.But those of 5 children with CH and 32 cases with Hashimoto's thyroiditis were not significantly changed.Conclusions The GH-IGF axis is inordinate in the CH children,which is an important reason of stature short.Early thyroxine substitute therapy is very helpful to maintain normal growth and development of children with CH.

Objective:To evaluate the clinical efficacy of acupuncture plus tuina in treating cervical vertigo (CV).Methods:One hundred CV patients were randomized into an observation group and an acupuncture group by the random number table,with 50 cases in each group.The acupuncture group received acupuncture at Xiang Ba Zhen (eight acupoints on the nape);the observation group received tuina treatment in addition to the Xiang Ba Zhen acupuncture.The two groups were both treated once every other day for 10 sessions in total.The two groups were examined by transcranial cerebral Doppler (TCD) before and after the treatment,and their therapeutic efficacies were evaluated.Results:After the treatment,the mean velocity (Vm) of vertebral artery (VA) and basilar artery (BA) showed significant improvement in both groups (all P＜0.001);there were significant differences in the Vm of VA and BA between the two groups (both P＜0.05).The total effective rate was 100.0％ in the observation group versus 82.0％ in the acupuncture group,and the difference was statistically significant (P＜0.01).Conclusion:Xiang Ba Zhen acupuncture as a monotherapy or used together with tuina can improve CV,but Xiang Ba Zhen plus tuina can produce a more significant efficacy.

Objective To explore the methods and the effect of the surgical treatment of patients with chronic ischemia of extremities.Methods In recent 6 years,the clinical data of 75 patients,including 7 upper(extremities) and 71 lower extremities with chronic ischemia,treated surgically were reviewed retrospectively.The surgical treatment included: traditional operation in 65 cases,interventional surgery in 4 cases and stem cell transplantation in 6 cases.Results Sixty-three patients(66 extremities) were followed up from 2 to 56 months after the surgical treatment,and the result showed that 9 extremities of 8 patients were amputated(within) 1 year(13.6%).In the other cases(83.3%),the ischemic symptoms were relieved or(disappeared),the ulcer healed or the amputating level had lowered(3.0%).The effective rate of the surgical treatment was 86.3%.Conclusions The appropriate surgical treatment of chronic ischemia limbs should be choiced based on the ischemic state of the limb,and a satisfactory result can be obtained in most patients.
