Objective:To investigate the factors influencing the prognosis of patients with estrogen receptor (ER)-positive de novo stage Ⅳ breast cancer.Methods:The clinical data of 339 patients with ER-positive de novo stage Ⅳ breast cancer treated in Tianjin Medical University Cancer Hospital and Cangzhou Hospital of Integrated TCM-WM from February 2010 to December 2017 were retrospectively analyzed. Related factors such as age, time of chief complaint, the clinical T/N stage, site of metastasis, expressions of molecular markers and treatment mode were included. Univariate log-rank test and multivariate Cox regression model were used to analyze the effects of prognostic factors on patients' overall survival (OS).Results:Univariate analysis showed that there were statistically significant differences in the OS of patients stratified by clinical N stage at first diagnosis, metastasis sites at first diagnosis, ER expression, progesterone receptor (PR) expression, Ki-67 positive index and p53 expression, endocrine therapy, chemotherapy at first diagnosis, surgery and radiotherapy of the primary lesions (all P < 0.01). Multivariate Cox regression analysis results showed that metastasis sites at first diagnosis, Ki-67 positive index, surgery and radiotherapy of the primary lesions were all independent influencing factors of OS for breast cancer patients (all P < 0.01). Conclusions:Patients with ER-positive de novo stage Ⅳ breast cancer have a good prognosis when they have oligometastasis, Ki-67 positive index ≤ 20%, and they receive surgery and radiotherapy of the primary lesions.

OBJECTIVE: To explore the genetic etiology for a Chinese pedigree affected with Alazami syndrome. METHODS: Genomic DNA was extracted for 2 patients and 2 unaffected members from the pedigree. Whole exome sequencing was carried out to detect potential variant in the proband, and the result was verified by Sanger sequencing. RESULTS: The proband and her sister were both found to harbor compound heterozygous variants of LARP7 gene, namely c.94A>T (p.Lys32*) and c.1141A>G (p.Lys381Glu), which were inherited from their father and mother, respectively. Both variants were predicted to be pathogenic based on bioinformatic analysis. CONCLUSION The two variants of the LARP7 gene, both were unreported previously, probably underlay the Alazami syndrome in this pedigree. Above finding has expanded the mutational spectrum of the LARP7 gene.

OBJECTIVE: To determine the effect of lung protection mechanical ventilation on respiratory function in the elderly undergoing spinal fusion. METHODS: Sixty 70-85 year old patients, ASA class II or III, undergoing spinal fusion were randomly assigned into 2 groups (30 in each group): a protection mechanical ventilation group (group P) and a conventional mechanical ventilation group (group C). Low VT and low level positive end expiratory pressure (PEEP) mechanical ventilation were applied in group P (VT=6mL/kg, RR=12-18 b/min, I:E=1:2, PEEP=10 cmH2O, alveolar recruitment performed once every 15 min), while traditional ventilation was used in group C ( VT=10-12 mL/kg, RR=12 b/min, I:E=1:2). Arterial blood samples were taken and pH, PaO2, PaCO2, PaO2/FiO2, A-aDO2, HR, SBP, DBP and CVP were recorded before the operation (T0), 1 h after tracheal intubation (T1), tracheal extubation immediately (T2), 1 h after tracheal extubation (T3), 1 d, 2 d, and 3 d after the operation (T4, T5, and T6). The pulmonary complication was also examined 1 d after the operation. RESULTS: At T1, T2, T3, T4 and T5, PaO2 and PaO2/FiO2 in group P were higher than those in group C, but A-aDO2 in group P was lower than that in group C. Five patients had bronchitis, 5 had hyoxemia, and 3 had atelectasis in group C, but 2 bronchitis in group P. The incidence of pulmonary complication was 43.3% in group C and 6.6% in group P. There was no significant difference in HR, SBP, DBP and CVP between the 2 groups. CONCLUSION Lung protection mechanical ventilation improves the arterial oxygenation and accelerates the recovery of respiratory functions in elderly patients after spinal fusion operation, with no influence on hemodynamics.

Objective To explore the association of CD22 gene T＞A locus (SNPrs2267574) with the development of systemic lupus erythematosus (SLE) and SLE phenotypes in Southern Chinese Han people.Methods Two hundreds fifteen cases and 216 normal controls were enrolled with the aim of case-control design,and the genotype was determined by PCR-RFLP.We calculated X2 and ORs for association study.Results In CD22 gene T＞A locus,there was significant difference of genotypes distribution between cases and controls (X2=6.086,P＜0.05).The frequency of AT genotype was higher in cases than in controls (OR=1.68,95%CI:1.08～2.60,P=0.021 ),and A allele had a higher proportion in cases (OR=1.58,95%CI:1.09～2.29,P=0.015).Meanwhile,the frequency of A allele in patients with positive anti-SSA was higher than in patients with negative anti-SSA (OR=3.69,95%CI:2.08～6.52,P＜0.01 ).Conclusion In Southern Chinese Han population,CD22 gene T＞A locus is associated with the development of SLE and the A allele has positive association with anti-SSA.

Objective To evaluate the value of echocardiography method for diagnosis of the downward displacement of the posterior leaflet of tricuspid valve with apical right heart two chamber view (AP-RH-2CV). Methods Rotating the probe clockwise from apical four chamber view(AP-4CV) to AP-RH-2CV at the septial and posterior leaflet of tricuspid valve, the shape, moving and position of the posterior leaflet of the tricuspid valve were observed by displaying the degree of downward displacement of the septial and posterior leaflet of tricuspid valve. The location of the orifice of tricuspid regurgitation was examined by color Doppler flow imaging(CDFI). Results In 15 patients with Ebstein's anomaly from the AP-RH-2CV, the downward displacement of posterior leaflet of tricuspid valve was clearly observed at the AP-RH-2CV. These results of echocardiography were confirmed by surgery except one ease missing out mild downward displacement of the anterior leaflet of tricuspid valve. Moreover, all 15 patients showed the obvious downward displacement of the location of the orifice of tricuspid regurgitation from AP-RH-2CV by CDFI. Conclusions The AP-RH-2CV is an ideal view in diagnosis of the downward displacement of the posterior leaflet of tricuspid valve by echocardiography. The downward displacement of the location of the orifice of tricuspid regurgitation is a critical character for diagnosis of the downward displacement of the posterior leaflet of tricuspid valve by CDFI.

OBJECTIVE:To investigate the effect of the correlation between the use density of carbapenems and the bacterial drug-resistance.METHODS:The data including the use density of carbapenems in the ICU ward of a hospital,the categories of the related pathogenic bacteria and monitoring results on drug resistances in 5 consecutive years were collected for an analysis of the quantitative change in a corresponding stage.RESULTS:Non-fermentative Gram-negative bacilli(NFGNB) were prone resistant to carbapenems and the resistant rate fluctuated in relation to the use density of carbapenems.The Enterobacter had low resistance to carbapenems and was independent of the use density of carbapenems.CONCLUSION:The use density of carbapenems has a positive correlation with the resistance of NFGNB.Reasonable drug use density may slow down or reduce bacterial drug-resistance.

OBJECTIVE To evaluate the clinical features of tumors primarily in the pterygopalatine fossa, and the efficiency of surgical management for these lesions. METHODS The clinical data of 7 cases with tumors primarily in the pterygopalatine fossa were retrospectively studied. Three of them were primary diseases, i.e. fibrous histiocytoma, neurofibroma and cholesteatoma. The other 4 cases were secondary tumors mainly located in pterygopalatine fossa. There were 1 case with epithelial-myoepithelial carcinoma, 1 case with adenoid cystic carcinoma , 1 case with recurrent inverted nasal papilloma, 1 case with recurrent malignant fibrous histiocytoma. Approaches to tumors in pterygopalatine fossa lesions included lateral rhinotomy, and transnasal or transantrum approaches under the nasal endoscope. RESULTS The patient suffered from adenoid cystic carcinoma developed local recurrence 4 months after operation, and extended resection of the recurrent tumor with laser was performed again. No further recurrence was found after following-up for 3 years. Neither local recurrence nor regional metastasis was found in the remaining 6 cases with a follow-up period of 2 to 4 years. The main complication was oronasal fistula. CONCLUSION CT scan or MRI is the main method to the early diagnosis of pterygopalatine fossa tumors. Lateral rhinotomy, endoscopic trasnnasal or transantrum approaches are feasible procedures to resect the tumors.
