Background and purpose:This study aimed to explore the inlfuences on quality of life of patients with breast cancer in different stages undergone different styles of operations. Methods:During Apr. 2012 and Apr. 2013, a total number of 207 patients with breast cancer, including 61 patients undergone breast conserving surgery (BCS), 60 patients undergone immediate breast reconstruction (IBR) and 86 patients undergone modiifed radical mastectomy (MRM) reviewed or admitted in Beijing Tongren Hospital Afifliated to Capital Medical University were included in the research, in which FACT-B, SAS and SDS were used to assess the quality of life and negative emotions performing as the paired design. Results:The physical well-being, emotional well-being and the level of negative emotions such as anxiety and depression revealed signiifcant differences compared the patients who undergone BCS or IBR with those who undergone MRM in preoperative period (P<0.05), and there was no statistical difference in terms of other quality of life (P>0.05). At two and ifve years postoperatively, there was no signiifcant in the physical well-being, emotional well-being and negative emotions (P>0.05), whereas there was signiifcant differences in the other quality of life (P<0.05). Conclusion:BCS and IBR compared with MRM can obviously reduce the levels of preoperative negative emotions such as anxiety and depression, and improve the quality of life in long-term (two and ifve years postoperatively) to some degree.

With the aging of population, cerebral small vessel disease has attracted more and more attention. A growing body of literature has confirmed that retinal vascular changes can be used as a potential marker for the prediction of cerebral small vessel disease. The retina is recognized as a window into cerebrovascular and systemic vascular conditions. Combining traditional fundus photograph and fundus fluorescein angiography with optical coherence tomography angiography, the retinal vascular system of patients with cerebral small vessel disease can be comprehensively analyzed. This paper summarizes and analyzes the application of retinal angiography technology in different image types of cerebral small vessel disease and makes a review, in order to provide reference for the early diagnosis and prevention of cerebral small vessel disease.

OBJECTIVETo investigate the protective effects of adenovirus-mediated vascular endothelial growth factor (Ad-VEGF)165 gene transfer against hypoxic-ischemic brain damage (HIBD) in neonatal rats.

METHODSAd-VEGF recombinant adenovirus was constructed by bacterial homologous recombination technology. Seven-day-old Sprague-Dawley rats were randomly assigned to 4 groups: sham-operated (n=20), HIBD (n=25), buffer-treated (n=20), and Ad-VEGF-treated (n=25). The HIBD model was prepared by permanent occlusion of left common carotid artery, followed by exposure to 8% oxygen for 2 hrs. In the Ad-VEGF-treated and the Buffer-treated groups, 2 microL recombinant adenovirus suspension or buffer was injected into the left sensorimotor cortex of the rat brain 3 days after HIBD. Seven days after transplantation, VEGF165 mRNA expression was detected using RT-PCR. Neuronal apoptosis was detected by the terminal deoxynucleotidyl transferase-mediated biotinylated deoxyuridine triphosphate nickel end labeling (TUNEL). CD34 and VEGF protein were detected using immunohistochemistry. Microvascular density in the cerebral cortex was measured based on CD34 positive cells. A radial arm maze test was performed from 30 postnatal days to evaluate long-term learning and memory functions. At 35 postnatal days, the rats were sacrificed for cerebral histological examinations by hematoxylin and eosin.

RESULTSThe expression of VEGF165 mRNA increased in the Ad-VEGF-treated group more than in the untreated HIBD and the buffer-treated groups (p<0.05). The number of apoptotic neurons was less in the Ad-VEGF-treated group compared with that in the untreated HIBD and the buffer-treated groups (p<0.05). Microvascular density and VEGF positive cells increased in the Ad-VEGF-treated group compared with that in the untreated HIBD and the buffer-treated groups (p<0.05). In the radial arm maze test, the Ad-VEGF-treated group had more improved achievements than the HIBD and the buffer groups (p<0.05). Neuronal degeneration and necrosis were lessened in the Ad-VEGF-treated group compared with the HIBD and the buffer groups.

CONCLUSIONSAd-VEGF gene transfer can increase the expression of VEGF mRNA and VEGF protein, decrease neuronal apoptosis, and increase angiopoiesis in the brain. This attenuates brain damage and improves long-term learning and memory functions in neonatal rats after HIBD.

Objective To evaluate the efficacy of multimodal-antiemetic therapy on postoperative dizziness,headache,nausea and vomiting (PONV) in patients undergoing thyroidectomy.Methods One hundred patients (39 males and 61 females,ASA physical status Ⅰ or Ⅱ) scheduled for thyroidectomy were randomly divided into two groups according to random number table: control group (group C) and multimodal-antiemetic therapy group (group M).Two groups received total intravenous anesthesia (TIVA) with propofol and remifentanil.Prophylactic dexamethasone 10 mg were given after anesthesia induction and palonosetron hydrochloride 0.25 mg was used 30 min before the end of surgery in both groups.Mannitol 2 ml/kg in group M and the same amount of normal saline in group C were given 30 min before the end of surgery.The incidence of dizziness,headache and PONV were observed for 24 h in two groups.Results The incidence of headache was 5 cases (10%)and PONV was 5 cases (10%) in group M,which were respectively significantly lower than that of group C of 15 cases (30%) and 12 cases (24%) in 24 h after surgery (P<0.05).The additional antiemetic therapy for 24 h after surgery in group M of 2 cases (4%) was significantly lower than that of group C of 9 cases (18%) (P<0.05).Conclusion The multimodal-antiemetic therapy: prophylactic dexamethasone,palonosetron hydrochloride and mannitol were used 30 min before the end of surgery could significantly reduce the incidence of dizziness,headache and PONV after thyroidectomy.

Objective To investigate the relationship of high sensitivity C reactive protein (hs-CRP), interleukin-6 (IL-6)and soluble IL-6 receptor (sIL-6R)with the severity of clinical symptoms and coronary artery lesions in coronary heart disease (CHD)patients.Methods A total of 522 CHD patients were recruited and divided into three groups:stable angina pectoris (SAP),unstable angina pectoris (UAP)and acute myocardial infarction (AMI)groups.Another 102 healthy individuals served as normal controls (NCs).We calculated Gensini score according to the result of coronary angiography (CAG),collected clinical data and compared the groups. Multiple linear regression analysis was used to investigate the relationship of hs-CRP,IL-6 and sIL-6 R with Gensini score.Results The plasma hs-CRP,IL-6 levels were significantly higher and sIL-6R level was signficantly lower in SAP,UAP and AMI groups than in NC group (P<0 .0 5 ).There was a positive correlation between IL-6 level and Gensini score but a negative correlation between sIL-6 R and Gensini score presented by multiple linear regression analysis (P<0.05 ).Conclusion In CHD patients,plasma hs-CRP,IL-6 and sIL-6R levels are significantly related to the severity of clinical manifestations and coronary artery stenosis.These indicators may help predict the severity of CHD.

Aim To observe the effect of“Ying-nutrient and Wei-defense unblocking collaterals prescription”on the carotid sympathetic nerve in early atherosclero-sis. Methods The rabbits were randomly divided into 6 groups:Control group, high-fat group, Complex mod-el group, GSTL-H group, GSTL-L group and ATO group. The control group was fed with common food-stuffs, High-fat group with high-fat diet to build early atherosclerosis model, and all the other groups with high-fat diet combined with carotid artery cannula to build early atherosclerosis carotid artery injury rabbit model. All groups were given corresponding medicines intragastrically once a day for 4 weeks. The GSTL-H and GSTL-L group was given Guishaotongluo ultrafine powder 0. 6 g·kg-1·d-1, 0. 3 g·kg-1·d-1, and the ATO group was given suspension of atorvastain so-lution 2. 5 mg · kg-1 · d-1 . Biochemical method was used to detect blood lipid change. HE staining was ap-plied to observe the pathological morphology of intima-media, The content of NE in the carotid arterial was detected by ELISA. The immunohistochemical staining was used to detect the protein expression of NGF, TH around the carotid arterial. The expression of NGF, TH in the carotid artery adventitia was detected by Western blot. Results Compared with normal group, the levels of TC,TG and LDL-C in high-fat group and complex model group were significantly increased( P<0. 01). The degree of the intimal hyperplasia,the con-tent of NE and sympathetic density ( NGF, TH protein expression and distribution ) of the cartoid artery in complex model group were heavier compared with those in high-fat group; the lipid levels, degree of the inti-mal hyperplasia and sympathetic density ( NGF, TH protein expression and distribution ) in the GSTL-H, GSTL-L group were milder in varying degrees compa-ring with those in the complex model group(P<0. 05, P<0. 01 ) . Conclusion “Ying-nutrient and Wei-de-fense unblocking collaterals prescription” can reduce rabbit carotid atherosclerosis, and the mechanism may be related to regulating the sympathetic nerve of arterial wall.

BACKGROUND:Hip fracture has become one of the main reasons for morbidity, death and heavy medical costs in the elderly. With aging, the incidence of hip fractures in the elderly is increased day by day. OBJECTIVE:To investigate and analyze the incidence and distribution of hip fractures in middle-aged and old population from Changning District of Shanghai, China. METHODS:Medical records of patients with hip fracture ICD-9 CODE (femoral neck fracture and intertrochanteric fracture) admitted from July 2008 to June 2013 were col ected at the Changning District Public Health Information Center and Shanghai Shen Kang Medical Al iance Center. Population distributions of Changning District in 2010 and 2011 were provided by the Disease Control Center of Changning District. Then, the crude morbidity of hip fracture was calculated in terms of different ages and genders. For patients aged over 50 years, every 5 years served as an age group. RESULTS AND CONCLUSION:The incidence rate of hip fractures in the population aged over 50 years was 197.04/100 000, 88.51/100 000 in male and 304.73/100 000 in female. The annual standardized incidence rate of hip fracture was higher in female than male (P<0.05). The crude incidence rate of hip fracture was increased dramatical y in the population over 70 years, especial y in females. It indicates that the incidence rate of hip fractures is closed related to age, gender and osteoporosis.

Objective To summarize the first experience with ultrasound-guided percutaneous ab lation treatment (PAT) for recurrent hepatoblastoma (HB) after liver resection in children.Methods From August 2013 to April 2015,PAT was used to treat 6 children with a total of 9 recurrent HB,including 5 patients with 8 tumors in the liver and 1 patient with 1 tumor in the lung.The mean size of ablated tumors was (1.5 ± 0.8) cm,and the tumor size range was 0.7 cm to 3.1 cm.Results Four patients were performed percutaneous radiofrequency ablation (RFA) for recurrent HB;and 2 patients were performed percutaneous ethanol injection (PEI).Ablation success was achieved in all patients (6/6,100％).The complete ablation rate after the first ablation session was 88.9％ (8/9) on a tumor-by-tumor basis.Only 1 patient developed a fever with temperature ＞ 39 ℃;it was resolved by conservative therapy.During the follow-up period of 5-30 months,3 patients died to tumor progression.The 1-and 2-year overall survival rates after ablation were 83.3％ and 41.7％,respectively.Conclusions PAT is a safe and promising therapy for children with recurrent HB after liver resection,and further investigation in large-scale randomized clinical trials is required to determine its role in the treatment of this disease.

OBJECTIVETo compare the changes of nucleus pulposus after in vitro culture of rabbit whole intervertebral disc and spinal motion segment.

METHODSTwenty-one New Zealand white rabbits which were randomly divided into organ group with 8 rabbits and segment group with 13 rabbits. Fifty intervertebral discs and 50 spinal motion segments were harvested respectively under aseptic conditions from two groups. These specimens were maintained in organ culture with hyperosmotic media (410 mOsm/kg), then 10 discs of the two groups were observed respectively by HE staining, immunohistochemistry of collagen type III, proteoglycan content and cells viability of nucleus pulposus before culture and at 3, 7, 14, 21 days after culture.

RESULTSHE staining showed the intervertebral disc tissue structure remained intact after culture of 21 days organ group and 14 days segment group,but there was severely degenerated of 21 days segment group. The intensity value of type II collagen immunohistochemical staining in the nucleus pulposus were not changed significantly between 21 days organ group and 14 days segment group (P > 0.05), but the staining of segment group at 21 days became shallower, there was significant difference compared with before each time points and organ group at 21 days (P < 0.05). PAS/AB staining of proteoglycan of nucleus pulposus showed that there were not decrease of tinting strength of two groups within 7 days, but the strength weakened slightly of two groups at 14 days, and the tinting strength became weaker at 21 days segment group, the change is more obvious than the organ group. The intensity value of fluorescence staining of nucleus pulposus cells was not changed significantly within 7 days of two groups (P > 0.05), the intensity value decreased slightly at 21 days organ group and 14 days segment group, but there were no significant difference compared with before time points (P > 0.05) however at 21 days segment group the intensity decreased as cells viability of nucleus pulposus decreased,and there was a significant difference compared with before each time points and organ group at 21 days (P < 0.05).

CONCLUSIONIt is not obviously degenerated of the discs of organ group cultured within 21 days and segment group cultured within 14 days, but there was significant degeneration of the intervertebral disc of segment group after cultured 21 days, so the rabbit spinal motion segment can be used on research about the biomechanics of intervertebral disc as a vitro experimental model within 14 days.
