Objective To investigate the correlation between p21-actived kinase 1(PAK1) gene polymorphism and prognosis of endocrine therapy for breast cancer. Methods Polymerase chain reaction-restriction fragment length polymorphism was employed to analyze the genotype of PAK1 gene rs2298793 T→C polymorphism and rs2844327 C→T polymorphism of 105 patients with breast cancer accepting endocrine therapy. Prognostic factors such as age, state of menses, magnitude of tumor, pathological type, condition of operation, clinical stage, estrogen receptor, progesteron receptor, Her-2 and endocrine therapy drug were comprehensively considered, and Cox model was employed to analyze the relation of PAK1 genotype with the time-to-tumor progression (TTP). Results As to rs2298793C→T polymorphism, the TTP of CT genotype was shorter than TT genotype (P

OBJECTIVE: To evaluate the therapeutic effect of multi-plane operations in treating obstructive sleep apnea-hypopnea syndrome (OSAHS). METHOD: One hundred and fifteen patients with OSAHS diagnosed by polysomnography were treated with uvuplopalatopharyngoplasty. Eighteen of them were treated combining with nasal septal construction. Twenty six patients also received nasal septal construction and partial inferior turbinectomy. One patients also received Genioglossus advancement and partial resection of corpus linguae. Five patients also received partial resection of corpus linguae. Some patients with the nasal disease and/or the lingual hypertrophy; AHI > 40 and/or BMI > 30 are received tracheotomy before general anaesthesia. RESULT: According to the postoperative follow-up 43 patients, were cured, 46 patients were improved, 26 patients were invalid, the effective power was 77.4%. CONCLUSION The operative effective power were increased by multi-plane operations in OSAHS patients. The serious complication were prevented through tracheotomy before general anaesthesia in multi-plane operations of severe OSAHS.

OBJECTIVETo investigate the effect of Actinidia chinensis Planch polysaccharide (ACPS) on the growth and apoptosis of human gastric cancer SGC-7901 cells, and to explore the effect of SGC-7901 cells on p-p38 expression.

METHODSThe inhibition rates at different concentrations of ACPS on SGC-7901 cells at 24, 48, and 72 h were detected using CCK-8 method. Apoptosis ratios in SGC-7901 were determined by flow cytometry after 48-h treatment of different concentrations of ACPS. The expression of pro-caspase-9, PARP, and p-p38 in SGC-7901 cells after treated by different concentrations of ACPS was detected using Western blot. The expression of pro-caspase-9, PARP, and p-p38 was detected after SGC-7901 cells were pre-treated by p38 specific inhibitor.

RESULTSCompared with the control group, the optical density of SGC-7901 cells decreased after treated by 1, 2.5, 5, and 10 mg/mL ACPS (P < 0.05). Meanwhile, the longer the acting time, the lower the optic density (P < 0.01). IC50 was 7.43 mg/mL at 24 h; 3.88 mg/mL at 48 h, and 1.32 mg/mL at 72 h respectively. ACPS suppressed the protein expression of pro-caspase-9 (P < 0.01) and up-regulated the expression of PARP (89KD) (both P < 0.01). Further study showed that the protein expression of p-p38 was up-regulated in SGC-7901 cells treated by ACPS of different concentrations at 24 h (P < 0.05). The expression of phosphorylation p38 and the ACPS induced apoptosis of SGC-7901 cells could be inhibited after treated by specific inhibitor for 2 h.

CONCLUSIONSACPS could inhibit the growth of SGC-7901 cells and induce apoptosis. The underlying mechanism of inducing apoptosis was partially due to activating the p38MAPK path and further activating Caspase9 and PARP, finally leading to cell death.

Objective To discuss the pulmonary function change in infants with human bocavirus (HBoV) pneumonia or mycoplasma pneumonia (MP) and its clinical signiifcance. Methods One hundred and forty infants under 3 years old who were admitted due to pulmonary infection were recruited from January, 2013 to October, 2013. Among them, HBoV-DNA was detected in 64 cases, and MP-DNA was detected in 76 cases. Thirty eight normal age-matched infants were selected as controls. The shape of tidal breathing lfow-volume loops (TBFVLs) and change of every index were measured with a Pulmonary Testing System (Jaeger MasterScope). Results The ratio of time to peak tidal expiratory lfow (PTEF) to total expiratory time (TPTEF/TE), the ratio of VPTEF to expiratory volume (VPTEF/VE), tidal expiratory lfow at 25%of the remaining tidal volume (TEF25%) and the ratio of TEF25%to PTEF (25/PF) were signiifcantly decreased in infants with HBoV and MP infection as compared with healthy infants (P<0.05). However, there was no signiifcant difference of the above indices between infants with HBoV and MP infection (P>0.05). The shape of TBFVLs in infants with HBoV and MP pneumonia was changed and characterized by left-shifted PTEF and trough-like concave in descending limb. The PTEF was decreased in infants with pulmonary infection. Conclusions HBoV or MP infection results in impaired pulmonary function with manifestations of obstruction in small airway. The shape of TBFVLs in infants with HBoV and MP pneumonia is characterized by left-shifted PTEF and trough-like concave in descending limb.

OBJECTIVETo investigate the effect of baicalein on the gap junction intercellular communication (GJIC) in the TM4 Sertoli cells of the mouse testis and its related mechanism.

METHODSWe measured the cytotoxicity of different concentrations of baicalein on the TM4 Sertoli cells in the mouse testis by MTT, detected the fluorescence transfer of the TM4 Sertoli cells by parachute assay, and determined the expression of the protein connexin 43 ( Cx43) in the baicalein-treated cells by Western blot and immunofluorescence assay.

RESULTSBaicalein produced no obvious cytotoxicity on the TM4 Sertoli cells at the concentration below 60 µmol/L but significantly increased their GJIC at 0-20 µmol/L (P < 0.01). Western blot and immunofluorescence assay showed that 0-20 µmol/L baicalein remarkably elevated the expression of Cx43 in the TM4 cells (P < 0.01) and on the membrane of the TM4 cells.

CONCLUSIONBaicalein at the concentration of 0-20 µmol/L can significantly enhance GJIC in mouse TM4 Sertoli cells by increasing the expression of the Cx43 protein.

Objective To explore the clinical value and safety of early enteral nutrition support in patients after liver transplantation.Methods We retrospectively analyzed the clinical data of 86 cases who used early enteral nutrition support therapy after liver transplantation between January 2008and October 2011.All of patients were uproot the gastric tube at the first day after the operation,and gradual to the normal diet.The patients who used parenteral nutrition support therapy were as the control group(n＝112).Then we compared the data of patients in the two groups.Results The early enteral nutrition is more useful to the patients after liver transplantation than intravenous nutrition [In the seventh day after the operation,the control group's ALT was (45.2 ± 12.9) U/L,AST was (40.2±9.4) U/L,ALBwas (35.6±2.5) g/L,P＜0.05].The early enteral nutrition also can decrease hospital stay and hospital costs [(14.2±3.4) d,P＜0.05].Conclusion The early enteral nutrition is useful and safe to the patients after liver transplantation.

Objective To investigate the relationship between the level of serum uric acid(SUA) and carotid atherosclerosis in male patients with type 2 diabetes mellitus(T2DM). Methods A collection of 579 male T2DM patients with or without carotid atherosclerosis were grouped based on quartiles of SUA. Age, SUA, smokers, duration, body mass index(BMI), blood pressure, total cholesterol(TC), triglyceride(TG), high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol(LDL-C), blood urea nitrogen(BUN), creatinine(Cr), and HbA1C were determined in all subjects. The plaques in carotid arteries and intima-media thickness(IMT) were measured with high-resolution ultrasound. Results BMI, systolic and diastolic blood pressures, TG, and Cr showed a gradual increase, while HDL-C and HbA1C showed a gradual decrease according to the higher SUA quartiles in male T2DM(P＜0.05). Nevertheless, the detectable rates of smokers, duration, age, TC, LDL-C, and BUN had no relationships with the SUA quartiles(P＞0.05). The detectable rate of carotid atherosclerosis and the thickness of carotid plaque were positively associated with the levels of SUA in male patients with T2DM(P＜0.05). However, intima-media thickness of carotid arteries did not illustrate the correlation with the levels of SUA in male T2DM patients(P＞0.05). Age, HbA1C, and SUA were independent factors of carotid atherosclerosis in these patients by logistic regression(P＜0.05). Conclusion The levels of SUA seems to be associated with the occurrence and development of carotid atherosclerosis in male patients with T2DM.
