Objective To investigate value and effect of the bronchus was cut out and bronchoplasty for lung cancer. Methods Twenty-one patients with lung cancer which all invased out one bronchial orifice and precluded standard lobectomy. The present of endobronchial tumor was cut out according to the lesion region during operation, the bronchoplasty performed by health bronchial wall. Results There were squamous carcinoma in 15 patients; adenocarcinoma in 4; small cell lung cancer and carcinoid each one patient. Staging: stage Ⅰ in 3 patients; stage Ⅱ in 12, stage Ⅲa in 6. The 19 patients were uneventful after operation. The 2 cases died from acute pulmonary embolism or gastric irritable ulcer with large bleeding in perioperation. Respiratory failure in all patients had not occurred. Bronchoscopy performed immediately after operation in 16 patients and in the period of following up 6-36 months in 12 patients, the mucosa of bronchoplastic sites was smooth, no bronchial stenosis and no tumoral relapse.The period of following-up was 4-72 months, median survival 42 months after operation. Five patients died from the metastases or relapse. Life time in survival patients was well. Conclusion The bronchial resection by cut out and bronchoplasty for lung cancer had a good results in near future and long period, and proved individualized and adapted selective type of resection for bronchoplasty of lung cancer.

Objective To investigate the effects of adrenocorticotropic hormone (ACTH)combined with Huaiqihuang on hypothalamic pituitary adrenal (HPA) in rats. Methods Fifty rats were randomly divided into five groups according to the random number table method:normal control group (group A), prednisone group (group B), Huaiqihuang group (group C), ACTH group (group D) and combined treatment group (group E) with 10 rats in each group. Rats in group B, C, D and E were gavaged by acetic acid prednisone water solution 12.5 mg/(kg · d) for 4 weeks to establish HPA axis suppression model. Group A was given distilled water 10 mL/(kg·d) as control. Rats in group C and E were gavaged with Huaiqihuang 5 g/(kg·d) 30 minutes after intragastric administration of prednisone acetate. At the third week of the experiment, group D and E were subcutaneous injected with ACTH 200 μg/(kg·d). The serum cortisol levels were measured respectively at the start of the ex?periment, 2 weeks and 4 weeks of experiment. Animals were sacrificed at the end of the experiment, and then weights of the pituitary, adrenal glands and the viscera index were calculated. The pathological changes of the pituitary and adrenal glands were observed by HE stainning. Results After 2 weeks, the serum cortisol levels were significantly lower in group B, C, D and E than those of group A (P<0.05), suggesting that the model was successful. After 4 weeks, the serum cortisol levels were significantly higher in group C, D and E than those of group B (P<0.05), and between the treatment group the value was group E>group D>group C (P<0.05). At the same time, the weights of pituitary and adrenal gland and the viscera in?dex were higher in the three groups than those of B group (P<0.05). The HE staining showed that there were no significant changes in the distal part of the pituitary gland in five groups. The adrenal cortex zona was thinning and the structure was dis?ordered in group B. There were different degrees of hyperplasia in group C, group D, and group E, which was the most obvi?ous in group E. Conclusion ACTH combined with Huaiqihuang can promote adrenal cortex zona hyperplasia and cortisol secretion, which reduces the glucocorticoid induced inhibition of HPA axis in rats.

Objective To evaluate the effects of the right stellate ganglion block on the expression of β3adrenoceptor (β3-AR) in rabbits with heart failure.Methods Forty-eight Japanese white rabbits of both sexes,weighing 2.5-3.0 kg,were randomly divided into 3 groups (n =16 each):sham operation group (group S),heart failure group (group HF) and right stellate ganglion block group (group RSGB).Heart failure was induced by occlusion of left anterior descending branch of coronary artery and confirmed by ultrasonic cardiography 4 weeks later.A PE-10 catheter was inserted into the right stellate ganglion for administration of drugs.0.25％ bupivacaine 2 ml was injected through the catheter once a day for 2 weeks in group RSGB,while the equal volume of normal saline was injected instead of bupivacaine in S and HF groups.The left ventricular end-diastolic diameter (LVEDD),left ventricular end-systolic diameter (LVESD),ejection fraction (EF) and left ventricular fractional shortening (LVFS) were measured at 1 day before ligation (T0),before catheter insertion (T1),before 8th administration (T2),and 1 day after the last administration (T3).Eight rabbits were sacrificed at T1 and T3 in each group and myocardial specimens were obtained from the apex of the left ventricle for determination of the expression of β3-AR by Western blot.Results Compared with group S,the LVEDD and LVESD were significantly enlarged and LVEF and LVFS were decreased at T1-3,and the expression of β3-AR was up-regulated at T1,3 in groups HF and RSGB (P ＜ 0.05).Compared with group HF,the LVEDD and LVESD were significantly decreased,LVEF and LVFS were increased,and the expression of β3-AR was significantly down-regulated at T3 in group RSGB (P ＜ 0.05).Conclusion The right stellate ganglion block can improve the cardiac function of rabbits with heart failure through down-regulating the expression of β3-AR in myocardium.

Aim To explore inhibitory effects and mechanism of engineering endostatin on growth and metastasis of melanoma cells in mice. Methods Melanoma cells(2× 106/mouse)were inoculated sabcutaneously to C57BL/6 mice. After tumorigenesis,endostatin(8mg/kg.d)was administrated to tumor-bearing mice,once a day ,twenty-one in all.Dietetic state and weight change of the tumor-bearing mice were observed and tumorous sige was measured during administration of endostatin. On 26thday,the tumor-bearing mice were sacrificed,subcutaneously tumorous weight was weighed and brain,lung ,liver,spleen and kidney were excised and sections were made to supply the pathological examination. Results Area under curve in the endostatin-treated group was obviously less than that in tamor control group(P∨ 0.01). Pathological study revealed that lavge areal necrosis arose in tumor and newborn cappillaries around the tumor disapeared. Conclusion Endostatin possosses strongly inhibitory effects on growth and metastasis of mouse melanoma and formation of newborn capillaries around tumor.

Objective To observe the effects and safety of adrenocorticotropic hormone (ACTH) combined with Huaiqihuang on frequent relapse nephrotic syndrome (FRNS) in children. Methods Fifty-five child patients with FRNS were divided into control group, which was given glucocorticoid (GC) to maintain the treatment (group A, n=10), Huaiqihuang group (group B, n=17), ACTH group (group C, n=14) and ACTH combined with Huaiqihuang group (combined treatment group, group D, n=14). Continuous treatment was for 12 months. The GC treatment doses, the levels of basal secretion of adrenal cortex and adrenal cortex reserve were recorded at 6-month and 12-month respectively. And the recurrence rate and adverse reactions were observed in four groups. Results After 6-month treatment, the doses of GC were significantly lower in group C and group D than those in group A and group B (P<0.05). The levels of basal secretion of adrenal cortex were increased in turn in group A~D (P<0.05). After 12-month treatment, the doses of GC were significantly decreased in group C and group D than those in group A and group B, while the level of basal secretion of adrenal cortex and adrenal cortex reserve were increased (P<0.05). There were no significant differences in the doses of GC between group C and group D (P>0.05). After treatment for 6 months and 12 months, the recurrence rates of nephrotic syndrome were significantly lower in group C and group D than those of group A and group B (P<0.05). Conclusion The simple application of ACTH and the combination of Huaiqihuang can relieve the inhibition of long-term using GC on hypothalamic pituitary adrenal axis in FRNS patients.

Objective To identify the risk factors associated with cardiovascular and cerebrovascular disease (CCVD) in maintenance hemodialysis (MHD) patients. Methods We analyzed all of the patients undergoing maintenance hemodialysis in the dialysis center of the 3rd Affiliated Hospital of Sun Yat-sen University for at least 3 months from Jan 1st, 2009 to Dec 31st, 2014. Baseline and yearly interval clinical data were recorded and patients were followed up until morbidity or death of CCVD. Cox proportional hazard regression and time-dependent Cox regression were used to estimate the relative risk of outcomes associated with clinical measurements. Results There were 243 patients enrolled in the study, with a mean age of (53.2 ± 16.4) years old, and 138 of them were male (56.8%). The multivariate Cox proportional model revealed that age (HR=1.040, 95%CI:1.015-1.065, P=0.002), Erythropoietin (EPO) dose (HR=0.914, 95%CI: 0.846-0.987, P=0.022) and history of cardiovascular and cerebrovascular disease (HR=4.045, 95%CI: 2.074-7.890, P<0.001) were independent predictors of CCVD in MHD patients. After adjusting for baseline predictors, time-dependent serum phosphorus level (HR=1.722, 95%CI: 1.034-2.866, P=0.037) was significantly associated with CCVD. Conclusion Older age, decreases in EPO dose and history of cardiovascular and cerebrovascular disease were associated with increased risks of CCVD in MHD patients. Increase in serum phosphorus level was associated with increased risks of CCVD in a time-dependent manner.

Objective To study the imaging appearances of congenital splenorenal venous shunt,and to evaluate their clinical significances.Methods Of 127 283 patients who underwent upper abdominal CT scanning,6 patients were diagnosed to have congenital splenorenal venous shunt.The imagings were studied retrospectively.Plain scanning,enhanced CT and Doppler ultrasonography were performed on all these patients.Results The incidence was about 47/million.The six patients were all females,the age was between 32 to 67 years.The mean age was 48.8 years.Enhanced CT demonstrated that there were twisted and dilated shunting blood vessels between the splenic and renal veins.The diameters in four patients were larger than the splenic and portal veins.In the remaining two patients,they were smaller shunting blood vessels.One patient had an associated absence of right portal vein.Two patients had associated dysplasia of portal veins and splenic veins.MPR,CPR,MIP and VR could three-dimensionally depict the courses,the beginnings and the ends of the splenorenal shunts.Doppler ultrasonography showed counterflow between the portal and splenic veins,and showed the blood in the splenic vein to flow into the left renal vein.Conclusions A congenital splenorenal venous shunt is one of the rare form of congenital extrahepatic portosystemic venous shunts.Enhanced MSCT scan combining with its post-processing techniques could clearly demonstrate the shunt vessels and the associated lesions.Doppler ultrasonography could further demonstrate the shunt direction.
