Background and purpose:As a minimally invasive procedure, video-assisted thoracospic surgery for definitive resection of lung cancer is the focus of thoracic surgeons controversy.We studied the application of video-assisted thoracospic surgery and conventional thoracotomy for definitive resection of lung cancer from viewpoint of lymphadenectomy. Methods:From January 2001 to December 2005,549 patients with lung cancer underwent video-assisted thoracospic surgery lobectomy or pneumonectomy with systematic thoracic lymphadenectomy. The total number and average of dissected lymph nodes were recorded. Some studies on VAT and conventional lobectomy or pneumonectomy with systematic thoracic lymphadenectomy for lung cancer were compared.Results:In all 549 cases,7360 lymph nodes were dissected. The average of dissected lymph nodes was 13.41. There were no significant difference between video-assisted thoracospic surgery and conventional thoracotomy.Conclusions:Video-assisted thoracospic surgery should fulfill the same quality of lymphadenectomy WT5"and lung cancer radical resection.

Objective To investigate the changes of B type natriuretic peptide(BNP) and interleukin(IL)-33 levels and their clinical diagnostic values in different heart function classification of patients with heart failure.MethodsFrom January 2016 to January 2017,286 patients with heart failure in our hospital were selected as the heart failure group,while 106 healthy people were selected as the control group.The heart failure group was divided into New York Heart Association(NYHA)Ⅰ(n=76), NYHA Ⅱ(n=129), NYHA Ⅲ(n=61) and NYHA Ⅳ(n=20) according to the NYHA heart function classification criteria.The BNP and IL-33 levels were compared between heart failure group and control group,as so as the different heart function classification groups.And analyzed the factors related to heart failure by single factor and multivariate logistic regression.The diagnostic value of BNP and IL-33 in heart failure were analyzed by receiver operating characteristic(ROC) curve.ResultsThe level of BNP in heart failure group was significantly higher than that in control group(P<0.05),while IL-33 level was significantly lower than that in control group (P<0.05).The BNP levels in heart function classification groups had significant difference(P<0.05),but there was no significant difference in IL-33 level among them.Univariate analysis showed that both BNP and IL-33 were associated factors of heart failure, but multivariate logistic analysis showed that only BNP was an independent factor of heart failure.ROC curve showed that the area under the curve(AUC) of heart failure diagnosed of BNP was bigger than that of IL-33,the difference was statistically significant (P<0.05).ConclusionBNP and IL-33 can both effectively diagnose heart failure, but BNP is more diagnostic value.Besides, BNP can effectively reflect the cardiac function, the degree of disease and prognosis, witch can more scientifically guide the clinical treatment.

Aim:To predict ability of self-care at discharge of inpatients with first-ever cerebral infarction. Method: 346 stroke patients with first-ever cerebral infarction admitted to our hospital were analyzed,male 187,female 159,the average age was 63. 90± 11. 40 years and the average length of stay 36. 53±27.03days. Patients were divided into two groups, self-care and non self-care according to discharged outcome.Nineteen factors were selected from casenote and reports of laboratory and special exam such as EKG,CT or/and MRI. All material were analyzed (t test and X2 test,multiple regression). Result:The age in single factor analysis (P<0. 01)and six factors in regression analysis were significant differences in predicting discharged outcome between two groups. Conclusion:Main factors to predict the ability of self-care at discharge of inpatients were infarction of 1eft brain, large area, multiple focus, and accepted aphasia, arrhythmia as well as hemipareses, This research could be used for clinician to set a discharge plan and a guideline to select patients in early rehabilitation programs.

Ninety- five cases(49 male .46 female)with first heamorrhagic cerebral apoplexy. fromOct.1 . 1992 to Dec.31 .1993. were analyzed.The Average age was58.9. Patients were divided intotwo groups. the self care and the non- self care. Ninteen variables which were supposed likely to be relatedto functional outcome were chosed from the admitted record of each patient and analyzed with mutltiple lo-gistic regression. Results showed that the major predictors of poor outcome are coma. incontinent and hemi-plegia at onset and abnormal blood urea nitrogen. pulmonary infection and bleeding amount more than 3 0ml at admitted.Cases older than 70 years.high blood presure longer than 20 years have a tendency of moredependence in functional abilities.Factors that do not predict outcome after heamorrhagic stroke are sex.days in the hospital,cormorbidities. as well as level of blood surgar and cholestral.EKG changes at admitted time.

Objective To retrospectively explore the incidence and causes of apnea after operation for retinopathy of prematurity(ROP). Methods The clinical data of 17 premature infants with operation for ROP(ROP group)and the other 23 premature infants without ROP(control group)were collected.The occurrence of apnea(time of onset and remission and original diseases) was recorded after operation in ROP group and at adjusted 37 weeks of gestational age in control group.Follow-up was conducted for 4 weeks,and the prevalences of apnea were compared between these two groups.Results There was significant difference in prevalenees of apnea between ROP group and control group ( 52.9%vs 21.7%,P<0.05).In ROP group,time of occurrence of apnea was (38±40)h after operation,and time of remission was (126±145)h after onset.Among the infants with apnea,there were 3 cases of pneumonia(33.3%),1 case of hypoglycemia(11.1%)and 5 cases with unexplained causes(55.5%). Conclusion Infants after operation for ROP are more prone to apnea,and pediatricians and ophthalmologists are required to collaborate in the perioperative care.

Aim To discuss the effectsof extract from fermented buckwheat flower and leaf(EFBFL) on myocardial injury in spontaneously obese type Ⅱ diabetic db/db mice and its mechanism.Methods 9-week-old male db/db mice were randomly divided into high level EFBFL dose group(EFBFL-H, 0.1 g·kg-1), low level EFBFL dose group(EFBFL-L, 0.05 g·kg-1),metformin hydrochloridecontrol group, model control group, and normal control group, with 10 mice in each group.All groups were treated with 8 wks of drugs by gastric perfusion.The random blood glucose(RBG) was tested respectively at the end of 2nd, 4th, 6th, and 8th wk.Finally, the levels of creatine kinase(CK) creatine kinase MB(CK-MB), andadvanced glycosylation endproducts(AGEs) were detected after 8 wks.The morphological changes of myocardium were observed under light microscope by HE staining, and the ultrastructure of myocardium was observed under electron microscope.Immunohistochemical method and Western blot were used to detect myocardial tissue glucose transporter-4(Glut-4).Results EFBFLcould repress patho-proceeding of myocardial fibrosis efficiently, and significantly decrease the level of blood glucose, CK,CK-MB, and AGEs in db/db mice.Meanwhile, it could increase the expression of Glut-4 in myocardial tissues of mice.Conclusions EFBFL can prevent myocardial injury in spontaneously obese type Ⅱ diabetic db/db mice.The possible mechanism may be related to lowering the level of blood glucose and serum AGEs and up-regulating Glut4of cardiac muscle.

[ ABSTRACT] AIM:To observe the effect of oleanolic acid ( OA) on the expression of Tumor necrosis factor-α( TNF-α) and collagen in silicotic rats in vivo and its possible mechanism.METHODS:Male Wistar rats were divided in-to 4 groups according to the randomized block design:control group, model group, OA group and solvent control group (20 rats in each group) .Except control group, the rats in other groups were induced by intratracheal instillation of silicon di-oxide (SiO2;250 mg/kg).The rats in OA group were intragastrically administered with OA (60 mg/kg) from the second day of giving SiO2 .The rats in solvent control group were gavaged daily with 0.6%sodium carboxymethyl cellulose solution (10 mL/kg).The rats in control group were given normal saline under the same condition for 56 consecutive days.All rats were killed at the 7th, 14th, 28th and 56th days.The lung coefficient was detected and the morphological changes were ob-served.The serum contents of TNF-αwere detected by ELISA.The content of total collagen in the lung tissue was meas-ured.The protein level of nuclear factor-κB ( NF-κB) in the lung tissue was determined by immunohistochemical method. RESULTS:(1) According to the morphological changes, the silicosis model was successfully established.Compared with control group, the lung coefficient and total collagen increased obviously in model group and solvent control group.The lung coefficient and total collagen content in OA group at each time point reduced compared with those in model group and sol-
vent group, and increased compared with those in control group at the corresponding time points.(2) The serum contents of TNF-αin model group and solvent control group significantly increased, peaking at the 14th day, slightly decreasing af-terward, and showing statistically significant difference at each time point compared with those in control group.No signifi-cant difference between model group and solvent group at different time points was observed.OA had inhibitory effect on the contents of TNF-αcompared with model group and solvent group at the corresponding time points.(3) NF-κB in model group and solvent control group significantly increased, peaking at the 28th day, and showing statistically significant differ-ence at each time point compared with those in control group.The NF-κB expression in OA group was similar to model group, but significantly decreased compared with control group at each time point.CONCLUSION: OA inhibits the ex-pression of TNF-αand collagen and attenuates the silicosis fibrosis, which may be related to the NF-κB pathway.

OBJECTIVETo explore the long-term effects of the uvulopalatopharyngoplasty (UPPP) combined with oral appliance (OA) in the treatment of obstructive sleep apnea hypopnea syndrome (OSAHS).

METHODSThirty patients with severe OSAHS confirmed by polysomnography (PSG) according to their apnea hypopnea index (AHI) and lowest SaO2 during sleep were selected using random permutation table and divided into only UPPP group(U group, n = 15) and UPPP with OA group (UA group, n = 15). The follow-up period was 2 years. PSG was performed in 0.5 year and 2 years after operation. AHI, lowest SaO2 and Tmax were tested and evaluated.

RESULTSThe effectiveness of two groups was the same after 0.5 year. Two years after operation, the values [AHI: (18.06 ± 2.24) times/h; lowest SaO2: (88.64 ± 10.37)% and Tmax: (20.5 ± 17.6) s] in UA group were better than that [AHI: (49.73 ± 3.35) times/h; lowest SaO2: (79.56 ± 4.87)% and Tmax: (41.3 ± 19.7) s] in U group. The number of effectiveness was 9 and the number of ineffectiveness was 6 in U group, while in UA group, the number of effectiveness was 14 and the number of ineffectiveness was 1(P < 0.05).

CONCLUSIONSLong-term result of combined treatment was better than that of UPPP only.
