Objective To compare the surgical outcomes between laparoscopic and open surgeries in treatment of ectopic oviduct pregnancy, and investigate the clinical value of laparoscopic surgery. Methods Two hundred and forty-six patients with ectopic oviduct pregnancy in our hospital from June 2009 to March 2013 were retrospectively analyzed. 134 cases were treated with laparoscopic operation and 112 with open surgery. Some parameters such as operative time, blood loss, usage of pain-killer, hospital stay were compared between both groups. Results All operations were successful. Laparoscopic surgery was shown to be superior to open operation in the parameters of operative time, blood loss, usage of pain-killer and hospital stay ( < 0.05) . Conclusion Compared with open operation, laparoscopic surgery has the advantages of less trauma and rapid postoperative rehabilitation. It may become the first line treatment for ectopic oviduct pregnancy.

Objective: To investigate the factors affecting macular degeneration (MD) in middle-aged and elderly populations, so as to provide the reference for prevention and treatment of MD. Methods: People at ages of 50 years and older who were admitted to ophthalmology department of Hangzhou First People's Hospital and received MD screening were selected as the study subjects. General information including age, gender, eye-using habits and family history of MD were collected by questionnaire surveys. MD was diagnosed by ophthalmological examination, and the prevalence of MD in middle-aged and elderly people was analyzed. A multivariable logistic regression model was used to identify the influencing factors of MD. Results: A total of 2 832 people were investigated, including 1 527 males (53.92%) and 1 305 females (46.08%), and 1 878 people (66.31%) aged 70 years and older. There were 498 people (17.58%) with good eye-using habits, 1 180 (41.67%) with general eye-using habits and 1 154 (40.75%) with poor eye-using habits. There were 1 817 people with family history of MD (64.16%). Multivariable logistic regression analysis showed that people at ages of 70 years and older (OR=2.815, 95%CI: 1.350-5.871), with poor eye-using habits (OR=2.354, 95%CI: 1.373-4.035), with family history of MD (OR=2.782, 95%CI: 1.138-6.799), with cataract (OR=2.593, 95%CI: 1.157-5.815) and with visual central defect (OR=2.601, 95%CI: 1.252-5.404) had a higher risk of MD. Conclusion Age, eye-using habits, family history of MD, cataract and visual central defect are influencing factors for MD in middle-aged and elderly populations.

Background and purpose:This study investigated the value of cervical ultrasound and TSH-sup-pressed thyroglobulin in the diagnosis of recurrence or metastasis of differentiated thyroid carcinoma (DTC).Methods:This study analyzed the data on 196 thyroid carcinoma patients who underwent neck dissection after clinically sus-pecious recurrence of DTC in Peking Union Medical College Hospital from Aug. 2010 to Dec. 2014. Among the 196 patients, 62 patients sonographically suspecious recurrence after total thyroidectomy and/or radioactive iodine ablation therapy were enrolled in this study. The ultrasonic features of lymph node involvement were retrospectively analyzed. The value of the ultrasonic features in the diagnosis of lymph node involvement and a TSH-suppressed serum Tg level in the diagnosis of recurrence or metastasis of DTC was also evaluated.Results:Of the 62 patients, 59 were pathologi-cally conifrmed with lymph node involvement, 1 case with local recurrence and 2 cases without recurrence or metasta-sis. There were 121 ultrasonographically suspected lymph nodes, conifrmed by pathology, 92 were metastatic ltsions, 25 were non-metastatic, 3 were ifbrous tissue and 1 was striated muscle. The positive predictive rate of cyst, calciifcation or hyper-echogenicity in cortex was 100% in the diagnosis of lymph node involvement. There was a signiifcant difference in disordered vascularity and cyst in cortex between metastatic and non-metastatic lymph nodes. Forty-nine patients were positive for Tg, whereas 13 were negative. The accuracy, sensitivity and speciifcity of TSH-suppressed serum Tg in the diagnosis of recurrence or metastasis of DTC were 82.3%, 81.7% and 100%.Conclusion:The disordered vascularity and cyst in cortex of the lymph node are highly speciifc indexes in diagnosing lymph node involvement. TSH-suppressed serum Tg level has high diagnostic value for detection of recurrence or metastasis of DTC. Cervical ultrasound can identify recurrent or metastatic lesions in both Tg-positive and Tg-negative patients.

Objective To test the hypothese that extreme low estrogen level will lead to elevation of blood pressure.Methods Thirty-two adult male SD rats were submitted to following approaches:control(n=8),orchi- ectomy(n=8),orchieetomy plus letrozole,an inhibitor of estrogen synthese [5 mg/(kg?d)by gavage,n=8], letrozole treatment in intact testis rats(n=8).Four weeks after treatment,SBP,serum testosterone(T),estradiol (E_2),nitric oxide(NO),endotheline(ET),thromboxane(TXB_2),prostacyelin(6-Keto-PGF_(1?)),atrial naturetic pep- tide(ANP),C type natriuretic peptide(CNP)were determined.Results SBP was increased significantly after or- chiectomy compared with control rats(orehiectomy:171?17 vs control:156?14 mmHg,P

Objective To investigate the apoptosis of T lymphocytes,the expression of Bcl-2, Fas on the peripheral blood T lymphocytes in end stage renal disease patients;and to explore the characteristics of Th1 /Th2 profile and the influence of dialysis membranes with different permeability on the apoptosis of T lymphocytes of maintenance hemodialysis patients.Methods The study included 10 non-dialyszed (ND)patients,45 maintenance hemodialysis patients with cellulose acetate (CA) membranes(13),low-flux polusulfone(PS-LF) membranes(16),high-flux polusulfone (PS-HF) membranes (16) and 8 healthy volunteers (C).The apoptosis of T lymphocytes,expression of Bcl-2,Fas on peripheral blood T lymphocytes cultured with phytohemagglutinin (PHA) stimulation for 24 hours were measured by flow cytometry and immunohistochemical.ELISA was performed for detecting the levels of IFN-?and IL-4 in culture supematants.Results In ESRD patients,the apoptosis of T lymphocytes was greater than that of group C.Group CA was greater than group PS-HF and group PS-LF (P＜0.05).The expression of Bcl-2 on T lymphocytes in ESRD patients was lower than that of group C (P＜0.05).There was negative correlation between the T lymphocytes apoptosis and Bcl-2. The expression of Fas on T lymphocytes in ESRD patients was greater than that of group C (P＜0.05), and it was positive correlated with T lymphocytes apoptosis.The level of IFN-?of ESRD patients was decreased significantly compared with that in group C (P＜0.05),and there was negative correlation between T lymphocytes apoptosis and IFN-?.IL-4 was increased in ESRD patients (P＜0.05) and it was positive correlated with T lymphocytes apoptosis.Conclusions The accelerated apoptosis of T lymphocytes in ESRD patients may be related to the expression of Bcl-2 and Fas of T lymphocytes.ESRD patients show a suppressed secretion of IFN-?and an increased secretion of IL-4. T lymphocytes apoptosis of maintenance hemodialysis patients is influenced not only by the biocompatibility but also by the permeability of the dialysis membrane.

Objective To investigate the predictive value of the whole nodule size and solid component size of lung adenocarcinoma manifesting as subsolid nodule(SSN) in three different dimensions for pathologic grade.Methods We evaluated retrospectively preoperative chest HRCT data of 125 patients with 127 SSNs surgically resected and pathologically conformed lung adenocarcinomas.All specimens were divided into two groups: a total of 69 SSNs in group A, including 22 AIS and 47 MIA;a total of 58 SSNs in group B, only including IAC.Computer aided diagnosis software were used to measure the one dimension maximum diameter of solid component with lung window setting(1D-SCLW),two dimension maximum diameter of solid component with lung window setting(2D-SCLW),one dimension maximum diameter of solid component with mediastinal window setting(1D-SCMW),two dimension maximum diameter of solid component with mediastinal window setting(2D-SCMW),one dimension maximum diameter of whole nodule with lung window setting (1D-WNLW), two dimension maximum diameter of whole nodule with lung window setting (2D-WNLW), and volume of solid component with threshold of-300 HU (SCT) of all SSNs.Results 1D-SCLW, 2D-SCLW,1D-SCMW,2D-SCMW,1D-WNLW,2D-WNLW and SCT of the group B were significantly larger than those of the group A(P=0.000).ROC analyses indicated that the diagnostic efficiency of SCT for the pathologic grade was the highest among 7 CT features(AUC=0.887, sensitivity:81%,specificity:93%);The cut-off values of 1D-SCLW,2D-SCLW,1D-SCMW,2D-SCMW,1D-WNLW, 2D-WNLW and SCT were 17.50 mm,14.75 mm,9.50 mm,7.75 mm,0.50 mm,1.25 mm and 139.00 mm3.Multiple Logistic regression analysis revealed that SCT was the independent predictor of pathologic grade(OR=4.978,95%CI=1.430-17.331,P=0.012).SCT of 139.00 mm3 or greater was a significant indicator of IAC.Conclusion Among the whole nodule size and solid component size of SSN in three different dimensions on preoperative HRCT, SCT is found to be the independent predictor of pathologic grade, which may provide reference for surgery.

Objective To analyze the clinical value of continuous veno-venous hemofiltration (CVVH) treatment in children with severe hand-foot-and-mouth disease(HFMD) complicated with cardiopulmonary failure,via the prognostic comparison of the general comprehensive treatment and CVVH add-on treatment.Methods Fifty-one cases of severe HFMD with cardiopulmonary failure were divided into a CVVH group (n =19) and a control group(n =32) based on whether CVVH add-on or not.Their physiological and biochemical indicators were recorded and pediatric critical illness score (PCIS) and pediatric risk of mortality score (PRISM Ⅲ) were calculated within 24 hours,when they were diagnosed with neurogenic pulmonary edema (NPE)/pulmonary hemorrhage.Both groups were treated with endotracheal intubation,mechanical ventilation with high PEEP,corticosteroids,ulinastatin,actively lowering the intracranial pressure,fluid resuscitation,milrinone,dopamine and other vasoactive drugs,high-dose intravenous gamma globulin,the CVVH group were added with CVVH treatment(duration ＞ 12 h).Prognosis difference of CVVH add-on treatment after diagnosed with NPE/pulmonary hemorrhage by tracking indicators of the third day.Survival analysis between two groups were compared by 3-day survival rates,7-day survival rates,28-day survival rates and the finally survival rates.Results (1) The overall conditions of two groups were comparable when diagnosed with NPE/pulmonary hemorrhage.PCIS,PRISM Ⅲ,WBC counting,lactic acid,micro-blood sugar,myocardial enzymes and liver enzymes showed no significant difference between two groups.Three days after treatment,WBC and lactic acid decreased,but there was no significant difference (P ＞ 0.05),the remaining indicators had significantly improved in the CVVH group than those in the control group (P ＜ 0.05).(2) The 3-day survival rate,7-day survival rate,28-day survival rate and the finally survival rates in control group and CVVH group were 40.63 ％ vs.84.21％,37.50％ vs.73.68％,25.00％ vs.63.16％,18.75％vs.52.63％,the survival rate in CVVH group were significantly higher(P ＜0.05).(3)The survival curve indicated that the survival time of CVVH group was significantly longer than that of the control group,the median survival time were 17 d and 2 d,respectively,and the difference was statistically significant (P ＜ 0.05).(4)In the CVVH group,15 cases received CVVH after diagnosed with NPE/pulmonary hemorrhage within 12 hours,of which 10 cases(66.67％) ultimately survived,while the other 4 cases received CVVH after 12 h were all end to death,the difference was statistically significant(P ＜ 0.05).Further analysis of the impact of the timing of blood purification on the prognosis of children showed that the mortality rates of children received CVVH within 6 hours,6 to 12 hours,after 12 hours of diagnosis of NPE/pulmonary hemorrhage,were 2/8,3/7,4/4,respectively.Conclusion Continuous hemofiltration can significantly improve the prognosis of children with severe HFMD,and may be preferable to perform in early stage.

To study the chemo-preventive effect of the supercritical extracts from Angelica sinensis (SFE-AS) on induced colorectal carcinoma in mice by using the AOM/DSS-induced male mice colorectal carcinoma model, and discuss its possible action mechanism. Male Balb/c mice were subcutaneously injected with single dose of azoxymethane (AOM, 10 mg x kg(-1) body weight). One week later, they were given 2% dextran sodium sulfate (DSS) in drinking water for 7 days to induce colorectal carcinoma. Each drug group was orally administered with supercritical extracts from Angelica sinensis at 15, 30, 60 mg x kg(-1) until the 17th week. The tumor incidence rate of the SFE-AS group, mice tumor-bearing quantity and tumor-bearing volume of the SFE-AS group were lower than that of the AOM/DSS model control group, which may be related with the significant reduction of PCNA, COX-2, iNOS in the AOM/DSS-induced mouse colorectal carcinoma model associated with inflammation by SFE-AS. According to the results of this study, SFE-AS showed an intervention effect in the incidence and development of AOM/DSS-induced mouse colorectal carcinoma associated with inflammation, and could be further used in chemo-preventive studies on human colorectal carcinoma.

Objective To quantitatively assess the cardiopulmonary exercise function of spinal cord injury (SCI) patients and observe the effect of aerobic exercise on cardiopulmonary function, motor function and activities of daily living. Methods From December, 2014 to June, 2016, 34 incomplete SCI patients (ASIA C and D) and 23 healthy controls received cardiopulmonary exercise test (CPET). SCI pa-tients were randomly divided into conventional rehabilitation group (n=17) and aerobic exercise group (n=17). The aerobic exercise group received aerobic exercise for four weeks. They were assessed with CPET, motor and sensory function, walking index for spinal cord injury II (WISCI II) and spinal cord independence measure (SCIM) before and four weeks after training. Results Oxygen uptake (VO2)peak, anaerobic threshold (AT), metabolic equivalent of energy (METpeak), VO2/heart rate (HR)peak, respiratory exchange rate (RER)peak, minute ventilation (VE)peak, work rate (WR)peak and systolic blood pressure (SBP)peak were lower in the patients than in the controls (t>2.714, P<0.05). VO2peak、AT、METpeak、VO2/HRpeak、WRpeak increased in the aerobic exercise group after training (t>2.431, P<0.05). METpeak and WRpeak improved in the conventional rehabilitation group after training (t>3.282, P<0.01). The scores of motor in ASIA and SCIM improved in both groups after training (t>2.985, P<0.05). Conclusion The cardiopulmonary function decreased in incomplete SCI patients, which could be improved by moderate intensity aerobic exercise.
