Researches have demonstrated that gradually increased morbidity and mortality of cardiovascular disease may be related to vitamin D deficiency.But there are few randomized controlled studies about preventing cardiovas-cular events via vitamin D supplementation.This article summarizes investigate progress for related matter recently.

[Objectives]To probe into the nursing effects of comprehensive psychological nursing intervention for modified radical mastectomy in breast cancer patients. [Methods]160 breast cancer patients were randomly divided into Group A, control group B, experimental group(n=80). Group A was conventional y nursed as required, while to Group B, a supplement of comprehensive psychological nursing intervention was added, which concerned with pre-surgery cognition, emotion and attitude. [Results] Group B showed a notable improvement in their anxiety state after the nursing intervention, compared with Group A(P<0.05). In addition, the rate of satisfaction was far increased, and the average number of hospitalizing days was sharply decreased compared with Group A(P<0.05).[Conclusions]Comprehensive psychological nursing intervention for modified radical mastectomy in breast cancer patients can ease the pre-surgery anxiety, decrease the average number of hospitalizing days and increase the rate of hospitalizing satisfaction. It is proved to be an effective nursing intervention.

Patients receiving long-term anticoagulation therapy of vitamin K antagonist (VKA)may face risk of bleeding when receive surgery or invasive operation,and perioperative interruption of VKA may increase risk of thromboembolism.Bridging anticoagulation therapy with therapeutic dose of heparin group drugs may avoid throm-boembolic events induced by temporary interruption of VKA therapy during perioperative period.This article made a relative discussion.

Objective To study the dose-and time-effect relationship between lipopolysaccharide(LPS) and CD14 expression in the cell line J774A.1 of mouse macrophages. Methods The cell line J774A.1 was stimulated with different doses of LPS,and the CD14 surface-positive cells from the cell line J774A.1 were detected by flow cytometry(FCM)45 min after stained with FITC-CD14 monoclonal antibody. The changes of CD14 surface expression in the cell line J774A.1 at different time(1,2,4,8 and 16 h)after stimulated with LPS were observed.After the best stimulant time was selected,the cell line J774A.1 was treated with different doses(1,10,50,100,500 and 1 000 ?g?L~(-1))of LPS and the changes of CD14 surface expression were observed.(Results In view) of time-effect,compared with control group(the positive rate was 12.50?3.71),LPS significantly enhanced the CD14 expression at 1,2 and 4 h after stimulation(the positive rates were 23.80?5.07,(23.04?)2.88 and 28.22?1.54,respectively) when the dose of LPS was 1 ?g?L~(-1)(P

OBJECTIVE:To provide reference for the sustainable development of pharmaceutical enterprises in Guizhou prov-ince. METHODS:A questionnaire was conducted for 55 pharmaceutical enterprises in Guizhou province,the basic situation of en-terprises,familiarity of related directors to Good Manufacture Practice of Drugs(GMP)and relevant policy,the current situation of implementing the new version GMP were investigated and statistically analyzed,problems were found,and corresponding coun-termeasures were put forward. RESULTS & CONCLUSIONS:Totally 55 questionnaires were sent out,49 valid ones were received with effectively recovery of 85.1%. The results showed 43 enterprises(87.8%)had passed the GMP authentication;only 13 enter-prises(26.5%)directors were very familiar with the new version GMP. In terms of personnel management,the head of production management and quality management and the authorized person of quality and personnel had not yet met related requirements of the new version GMP fully;in terms of equipment and production management,production area transformation(clean areas,lounges, warehouses,water use) and air purification system design in most enterprises met related requirements of the new version GMP, 23 enterprises (46.9%) still can not conduct fully inspection to products and materials;in terms of document management,there were still some enterprises not meeting the new version GMP standards fully,enterprises'documents(health area layout,air purifi-cation layout,management procedures,operating procedures,etc.) of production site were imperfect. According to the investiga-tion,the main existing problems included lack of funds in implementing the new version GMP reform,not enough understanding or familiarity with the new version GMP,relevant personnel management not reaching the designated position,equipment and pro-duction management needing to be strengthened,document management systemic being poor,risk management being not sound, etc. It is suggested that government should give all forms of capital policy and strengthen the training of the new version GMP;en-terprises should attach great importance to the relevant personnel management,strengthen the equipment and production manage-ment,set up perfect document management system and a sound system of risk management.

Objective To compare clinical and laboratory characteristics between systemic lupus erythematosus (SLE) patients with and without cutaneous vasculitis,and to investigate the correlation of cutaneous vasculitis with severe visceral involvement and laboratory biomarkers.Methods A total of 152 SLE patients with various skin manifestations were enrolled from Department of Dermatology of Huashan Hospital affiliated to Fudan University from July 2011 to October 2014.The clinical and laboratory data were collected and retrospectively analyzed.SLE patients with cutaneous vasculitis were divided into upper/lower extremity vasculitis group and livedo reticularis group.A logistic regression model was used to analyze the correlation between cutaneous vasculitis and various clinical and laboratory variables.Results Of 152 SLE patients,62 (41％) presented with cutaneous vasculitis,including 55 with upper/lower extremity vasculitis and 7 with livedo reticularis,and 90 (59％) did not have cutaneous vasculitis.Patients with upper/lower extremity vasculitis showed significantly younger age (30.54 ± 12.67 years vs.37.77 ± 12.17 years),and lower prevalence of aberrantly elevated 24-hour protein excretion (39.39％ vs.64.00％) and serum urea level (2.08％ vs.16.43％),but significantly higher percentage of females (98.18％ vs.84.44％),higher proportions of patients with abnormal brain MRI (37.5％ vs.12.19％),anemia (87.03％ vs.70.93％) and positive antiribosomal P protein antibodies (77.77％ vs.53.65％),and higher SLE disease activity index (SLEDAI) (14.71 ± 7.75 vs.10.68 ± 5.61) than those without vasculitis (all P ＜ 0.05).The proportion of patients with decreased C3 level did not differ between patients with upper/lower extremity vasculitis and those without cutaneous vasculitis (P =0.362),but was significantly lower in the patients with livedo reticularis than in those without cutaneous vasculitis (28.57％ vs.79.76％,P =0.008).However,no significant differences in the other variables were observed between patients with livedo reticularis and those without cutaneous vasculitis (all P ＞ 0.05).Additionally,body mass index (BMI),abnormal lung function and other laboratory variables all did not differ among patients with upper/lower extremity vasculitis,patients with livedo reticularis and patients without cutaneous vasculitis (all P ＞ 0.05).Logistic regression analysis revealed that after exclusion of potential effects of age and gender,cutaneous vasculitis was significantly positively correlated with abnormal brain MRI (OR =4.24,95％ CI:1.17-16.13,P =0.028),and positive anti-ribosomal P protein antibodies (OR =3.97,95％ CI:1.86-8.47,P =0.0004),but negatively correlated with abnormally elevated 24-hour protein excretion (OR =0.25,95％ CI:0.09-0.69,P =0.009).Furthermore,cutaneous vasculitis showed no significant associations with abnormal serum urea level (OR =0.12,95％ CI:0.01-1.06),decreased C3 level (OR =0.93,95％ CI:0.38-2.28),anemia (OR =1.38,95％ CI:0.56-3.40) or SLEDAI (OR =1.05,95％ CI:0.98-1.14).Conclusions Cutaneous vasculitis is closely associated with central nervous system damage and emergence of anti-ribosomal P protein antibodies,so SLE patients with cutaneous vasculitis should be closely monitored for central nervous system damage.SLE patients without cutaneous vasculitis are more liable to kidney injury,so they also need to be closely monitored.

Aim To investigate the effect of small inter-ference RNA-mediated silcencing of the Bmi-1 gene on cell invasion and metastasis in human nasopharyngeal carcinoma cell line CNE-1 . Methods Chemically syn-thesized siRNA targeting the Bmi-1 gene was transfect-ed into CNE-1 cells, which had high invasive and me-tastatic potential. The expression of Bmi-1 mRNA and protein were detected by quantative Real-time PCR and Western blot, respectively. The effects of Bmi-1 knockdown on CNE-1 cells migration and invasion were analysied by Transwell migration assay and Matrigel in-vasion assay. Results Transfected with Bmi-1 siRNA significantly down-regulated the expression of Bmi-1 mRNA and protein as compared with the control group. CNE-1 cells transfected with Bmi-1 siRNA had lower levels of invasion and migration capacity than cells in the control group. Conclusion SiRNA-media-ted silencing of the Bmi-1 gene could significantly in-hibit cell migration and invasion in human nasopharyn-geal carcinoma cell line CNE-1 .

Objective To explore the operation points of the steps offront-typehypospadias operation in oral mucosa urethroplasty and scrubbed shaped urethra with meat membrane covering.Methods After correction of chordee of penis of 40 patients with Front -type hypospadias, oral mucosa was transplanted and fixed on albuginea surface at the one-third of ventral penile for all the patients to increase the width of the urethra and form the urethra with the selected appropriate size ureter. The skin of dorsal penile was transferred to ventral penile. After clearing the pedicled skin flap, the subcutaneous layer of meat was kept down, and stamped wholly on forming place of urethral reel (including both sides inferior of cut-off cavernous body of glans penis),forming the glans again.Results There was no ankylo-urethria among the 40 front-type hypospadias operation, ureteroscopy examination after two months of the operation showed that all the transplanted oral mucosa survived, and the stamped subcutaneous layer of meat located at both sides inferior of cut-off cavernous body of glans penis adhered with satisfaction,no glans incision dehiscence,there occurred 2 cases of urinary fistula which had been cured by neoplasty,there was 1 case of transferred flap necrosis which had been cured after dressing change.40 patients were satisfied with penis appearance after operation.Conclusion Following up the operation points of “front-type”hyospadias operation,the success rate of operation can be improverd obviously,the plastic effect is good,and the complications after operation can be reduced.stamped wholly on formed urethra.There is a small probability of incidence of urethral stenosis and urinary fistula after operation.

Objective Based on middle cerebral artery occlusion (MCAO) model,to investigate the effects of melatonin (MT) on DWI and expression of Fas,FasL and cleaved Caspase-3 proteins in rat model with focal cerebral ischemia.Methods Eighty SD rats were randomly divided into Sham group (n=16),MCAO group (n=32) and MT group (n=32).The rats in sham group were treated with sham-operation.And the rats in MCAO and MT groups were peritoneally injected with saline and MT respectively.The behavioral scores were assessed in the three groups.The rats in MCAO and MT group with the behavioral scores of 1 3 points were selected in the study.The DWI relative signal intensity (rDWI-SI),Fas,FasL and cleaved Caspase-3 proteins were respectively examined by MR scaning and immunohistochemical staining in all rats of each group at 6 h,24 h,72 h and 7 days after ischemia reperfusion (IR) or sham-operation.And the DWI and immunohistochemical results for each group were compared.Results At last,there were 16 rats in sham group,29 rats in MCAO group and 30 rats in MT group,respectively.There was significant difference of the behavioral scores among the three groups (x2 =50.125,P＜0.01).The behavioral scores of MT and MCAO groups were higher than those of sham group (all P ＜0.05).And the behavior scores of the MT group were lower compared with MCAO group after IR.Compared with the rDWI-SI values measured at 6 h,24 h and 72 h,7 days in sham group,the rDWLSI values of MT and MCAO groups were significantly higher (all P＜0.01).And the rDWI-SI was higher in MCAO group than those in MT group at 6 h,24 h and 72 h after IR (all P＜0.01).And there was no significant difference of rDWI-SI at 7 days after IR between MT and MCAO groups (P＞0.05).The immunohistochemical staining results showed that the number of Fas,FasL and cleaved Caspase-3 positive cells in MCAO and MT groups were significantly higher than those in sham group (all P＜0.01).And there were less Fas,FasL and cleaved Caspase-3 positive cells in MT groups compared with MCAO group (all P＜0.05) at 6 h,24 h and 72 h after IR.There was no significant difference of Fas,FasL and cleaved Caspase-3 positive cells among the three groups at 7 days after IR (P＞0.05).Conclusion MT can effectively alleviate the rDWI-SI value and inhibit the expression of Fas,FasL and cleaved Caspase-3 proteins in rats of focal cerebral ischemia.

Background and purpose: Three-incision esophagectomy for patients with esophageal cancer has been increasingly used, but the incidence of either postoperative anastomotic leak or stricture is higher than that in intrathoracic gastroesophageal anastomosis. The purpose of this study was to investigate the clinical effects of the side-to-side stapled cervical gastroesophageal anastomosis in preventing anastomotic leak and stricture after three-incision esophagectomy. Methods: One hundred and twenty-seven patients undergoing three-incision esophagectomy for esophageal cancer with gastric replacement were reviewed. A side-to-side stapled cervical gastroesophageal anastomosis was performed in 71 cases and manually sewn anastomosis in 56 cases. The incidence of postoperative anastomotic leak and stricture was compared between these two groups and the results were statistically analyzed using SPSS11.0 soft.Results: Anastomotic leakage was noted in seven patients (9.9%) in the stapler group and fourteen patients (25.0%) in the manually sewn group (P=0.04). After the operation two patients (2.8%) in the stapler group and nine patients (16.1%) in the manually sewn group developed a benign esophageal stricture (P=0.02).The incidence of either postoperative anastomotic leak or stricture in cases of the stapler group was significantly lower than that in the manually sewn group (P<0.05). Conclusion: Construction of the cervical esophagogastric anastomosis with a side-to-side stapled technique provides a larger luminal diameter which significantly reduces the incidence of postoperative anastomotic strictures. The surgery also greatly reduces the incidence of anastomotic leaks and strictures, so it could be used as an alternative strategy for cervical esophagogastric anastomosis after esophagectomy for esophageal cancer
