C erbB 2 is overexpressed in 20%～30% of human breast cancers,this oncoprotein plays an important role in predicting response to chemotherapy in breast cancer.Overexpression of c erbB 2 in breast cancer is associated with resistance or sensitivity to certain chemo therapeutic drugs, c erbB 2 can be expected to be a biological marker to direct chemotherapy in the treatment of breast cancer.

Objective We investigated urinary incontinence (UI) among patients of the Gynecological Department of Renmin Hospital of Wuhan University,to observe characteristics of women with UI in our province,and to analyze preliminary factors affecting their treatment.Methods We evaluated 15 300 patients treated for UI from August 2009 to April 2011,using site information and questionnaires.We also compared them to 66 825 other gynecology outpatients at our hospital over the same period.Results We found that the incidence of UI tended to increase with age,and was associated with body mass index,parturition,and surgery history.But 54.63％ (8358/15 300) of them refused surgical treatment.Of these 8358 patients,29.78％ (2489/8358) because of economic factors,25.83％ (2159/8358) because of mental stress,and 24.30％ (2031/8358) because of lack of faith in the efficacy of surgical treatment,20.09％ (1679/8358) did so because of knowing little of the disease.Conclusions UI is inconvenient to patients,and seriously affects their physical and mental health. Many patients refuse surgical treatment.Medical staff should attempt to educate patients better with regard to treatment,and to offer them help to improve the quality of their lives.

Objective To define urban community public health service programs by classification so as to better the mechanism of compensation for community health services. Mothods A preliminary classification of community health service programs was made in accordance with public product theories, which was then further improved by means of interviews with focal groups. Results At present a total of 99 community health service programs were offered in the cities under investigation, of which 45 were public health service programs, 21 para-public health service programs, and 33 private health service programs. Conclusion On condition that basic public health service is guaranteed, the government can make corresponding adjustments in compensation for public and para-public health service programs in light of economic development.

Objective To evaluate the video-assisted thoracoscopic surgery(VATS) in the diagnosis and treatment of open thoracic traumas. Methods From July 2003 to July 2008,video-assisted thoracoscopic surgeries,including thoracic exploration,repair of the pulmonary laceration,parietal pericardium and diaphragm,hemostasis,evacuation of the clotted hemothorax,and mini-incision thoracotomy,were carried out in 64 selected patients with open thoracic traumas. Results Via VATS,all the 64 patients were diagnosed accurately: pulmonary laceration in 43(56 lesions),pericardiac rupture in 7(one of them showed right ventricular rupture),diaphragmatic rupture in 9(5 of them were complicated with spleen rupture,1 with hepatic rupture,and 1 with gastric rupture perforation),single intercostal vessel injury in 5,and combined intercoastal vessel injury in 3.The procedures involved VATS pulmonary laceration repair in 24(combined with thoracic wall hemostasis in 2),VATS combined mini-incision thoracotomy pulmonary laceration repair with Endo-GIA in 11(silk suture was employed in 6,and pulmonary wedge resection in 2).Through VATS procedure,hemostasis and repair were completed for pericardiac repair in 3,and diaphragmatic repair in 5.Thirteen cases were converted to open thoracic surgery.The duration of VATS procedure ranged from 32 to 124 minutes with a mean of 65.8 minutes.After the procedure,6 patients developed pneumothorax,4 showed mild subcutaneous emphysema,and 9 had slight hemoptysis in 1 to 12 days after the treatment.The patients were followed up for 2 to 60 months(mean,28.5 months).Chest X-ray performed during the period showed no pleural effusion,pneumothorax or other trauma-related complications.Conclusion VATS is effective for the diagnosis and treatment of open thoracic traumas with less surgical injuries and good outcomes.

Background Medical refraction after cycloplegia is the preferable choice for precise measurement of degree of refractive error.Drugs used in China for cycloplegia include atropine and tropicamide,and the use of cyclopentolate is an alternative for ophthalmologist.However,the data for the evaluation and comparison of efficacy of the available drugs in cycloplegia is still lacking.Objective This system analysis was to evaluate the difference between atropine and cyclopentolate in cycloplegia in children.Methods A systematic literature retrieval was conducted in MEDLINE,EMbase,Google residual accommodation after cycloplegia by atropine and cyclopentolate were compared.Statistical analysis was performed using the RevMan 5.1.0 software.Results A total of 7 studies were included in this meta analysis,including 6 cohort study design and 1 randomized,doubleblinded clinical trial and 1232 eyes.For retinoscopic evaluation after cycloplegia,no significant differences were found between cyclopentolate and atropine in children with hyperopia and myopia (WMD =-0.21,95％ CI:-0.47-0.06,P=0.13 ; WMD =-0.10,95％ CI:-0.36-0.15,P =0.43).For residual accommodation after cycloplegia,no significant difference was seen between cyclopentolate and atropine in ammetropic children (WMD =0.30,95％ CI:-0.10-0.71,P =0.15).Conclusions Cyclopentolate shows the same effect on the cycloplegia as atropine in children,and it can take the place of atropine in cycloplegia in childhood.

Objective To detect the steroid sulfatase (STS) gene mutation in a Chinese pedigree with X-linked ichthyosis (XLI). Methods Genomic DNA was extracted from the peripheral blood of 3 affected patients and unaffected members in this family and 50 unrelated healthy volunteers followed by the amplification of the exon 1 and exon 10 of STS gene by PCR. Results Complete deletion of the exon 1 to 10 of STS gene was detected in all the patients in this pedigree with XLI, while no mutation was found in this gene in unaffected members of this family or normal human controls. Conclusion The complete deletion of STS gene is likely to be the main cause of the phenotype of XLI in this family.

Objective:To investigate the calcium-phosphate metabolic condition in maintenance hemodialysis patients with chronic kidney disease (CKD), and to observe the effect of large dose calcitriol on secondary hyperparathyroidism (SHPT).
Methods:We tested and compared the serum levels of calcium, phosphate, intact parathyroid hormone (iPTH), and alkaline phosphatase (AKP) in hemodialysis patients at different hemodialysis time (Group A with hemodialysis period≤3 years and Group B with hemodialysis period>3 years). We also detected those indexes before and after treating SHPT with large dose calcitriol. Twenty SHPT patients were divided into Group I (enlargement of parathyroid gland or nodule detected by color Doppler ultrasound) and Group II (normal parathyroid gland detected by color Doppler ultrasound).
Results:In the maintenance hemodialysis patients, the serum phosphate was (2.11±0.38) mmol/L and iPTH was (581.11±487.75) pg/mL. The serum level of iPTH in Group B was higher than that in Group A [(828.13±690.39) pg/mL vs (477.94±324.73) pg/mL, P<0.001]. In Group I, the serum level of iPTH [before vs after:(2471.7±898.3) pg/mL vs (2510.4±825.7) pg/mL] and AKP [before vs after:(524.2±18.8)U/L vs (511.3±19.3)U/L] did not change after the treatment of large dose calcitriol (P>0.05). In Group II, the serum level of iPTH [before vs after:(1358.5±302.8) pg/mL vs (369.3±43.4) pg/mL, P<0.001] and AKP [before vs after:(565.9±23.9)U/L vs (234.8±21.1)U/L, P<0.001] decreased signiifcantly after the treatment of large dose calcitriol.
Conclusion:Patients with longer time of hemodialysis have a higher level of iPTH. Large dose calcitriol can improve the clinical syndrome of SHPT, and decrease the level of iPTH and AKP in SHPT patients with normal parathyroid gland.
