Objective To evaluate the effectiveness of intervention for health risk factor in hospital employees. Methods This study was carried out among 339 employees of a hospital in Jinan, Shandong Province. Based on the results of Health Risk Appraisal for 14 health risk factors, we designed a 6-months intervention program for the most widely distributed and intervenable health risk factors; and then evaluated the changes of health risk factors after 6 months. Results After 6-month intervention the prevalence of 3 health risk factors decreased (P ＜ 0.05 ): physical inactivity decreased from 57.8% to 38.6%,hyperlipidemia from 9.4% to 5.3%, and unhealthy dietary from 28.9% to 14.8%. Compared with the baseline data, the average number of health risk factors were reduced from 3.10 to 2. 71 ( P ＜ 0. 01 ).Conclusion The intervention can reduce health risk factors effectively.

Objective:To investigate the effect of blocking the expression of receptor activity modifying protein 1 (RAMP1 )on calcito-nin gene-related peptide(CGRP)-induced MG-63 cell proliferation.Methods:RAMP1 siRNA was synthesized and screened by tran-scription in vitro.The subcultured MG-63 cells were divided into the following groups:RAMP1 siRNA interference group,empty vector group and blank control group.The mRNA expression and the membrane distribution changes of the calcitonin receptor-like receptor (CRLR)and the receptor component protein (RCP)in MG-63 cells were examined by real-time PCR and immunofluorescence method respectively.Results:RAMP1 and CRLR mRNA and the fluorescence intensity of MG-63 cells decreased after transfection by RAMP1 siRNA(P <0.05).In RAMP1 interference group,the expression of RCP mRNA and the fluorescence intensity were higher than those in the other two groups(P <0.05).After RAMP1 siRNA interference,the proliferation of MG-63 cells was inhibited(P <0.05). Conclusion:RAMP1 siRNA transfection may reduce CRLR expression and inhibite the proliferation of MG-63 cell.

Objective To apply the virtual reality in balance function training for Parkinson's Disease (PD). Methods From October, 2013 to January, 2016, 31 patients with balance disorders after PD were divided into two groups:the treatment group (n=17) received virtual reality balancing games training, while the control group (n=14) received routine balance training. They were assessed with Berg Balance Scale (BBS), Timed Up and Go Test (TUGT), static fall index (SFI), limits of stability (LOS), dynamic fall index (DFI) and modified Barth-el Index (MBI) before and four weeks after treatment. The frequency of falls in the next six weeks was recorded. Results The scores of BBS, TUGT, SFI, LOS, DFI and MBI improved significantly in both groups after treatment (P<0.05), and improved more in scores of BBS (t=2.095), TUGT (t=-2.091), DFI (t=-2.182), LOS scores (t=2.202) and MBI (t=3.036) in the treatment group than in the control group (P<0.05). There was positive correlation between scores of BBS and MBI (r=0.899, P<0.001). The frequency of falls was less in the treatment group than in the control group (P<0.05). Conclusion Virtual reality balance training can improve the balance function for PD.

Objective To determine the incidence of breast cancer?related lymphedema ( BCRL) in China and to analyze the associated risk factors. Methods A retrospective analysis was performed on the clinical data and the incidence of BCRL in 281 patients who were newly diagnosed with breast cancer and received surgery. The incidence of BCRL was evaluated using arm circumference measurement and Norman questionnaire. The risk factors for lymphedema were analyzed using chi?square test and logistic regression model. Results In all patients,the incidence rates of BCRL determined by arm circumference measurement and Norman questionnaire were 31?7% and 27?0%, respectively. The multivariate analysis showed that postoperative radiotherapy,a preoperative body mass index no less than 24 kg/m2 ,a large axillary lymph node dissection area,and a large number of positive axillary lymph nodes significantly increased the risk of BCRL (HR=2?87,P=0?042;HR=2?54,P=0?011;HR=1?97,P=0?037;HR=1?06,P=0?023). Moreover, patients with breast cancer and hypertension had 1?74?fold higher risk of BCRL than those with normal blood pressure. Conclusions The incidence of BCRL is still very high. However,most of patients only have mild edema. Postoperative radiotherapy, a large axillary lymph node dissection area, a large number of positive axillary lymph nodes,a high preoperative body mass index,and hypertension are risk factors for BCRL.

Objective:To discuss the clinic features and diagnosis of one case of hepatic angiomyolipoma (HAML) , and to analyze and summarize its diagnosis and treatment methods.Methods:The clinical materials of one case of HAML patient who was misdiagnosised as hepatocellcular carcinoma were analyzed retrospectively, and the related literatures were reviewed.Results:A middle-aged female patient visited our outpatient service because of low back discomfort.The upper abdominal CT and MRI suggested that a space occupying lesion located at the left lobe of liver inner lower segment, considering a high possibility of hepatocellular carcinoma.The patient underwent the left lobe of inner lower segmentectomy.The postoperative histopathological examination and immunohistochemical staining showed the tumour was HAML, After operation, the patient recovered well and the follow-up examination after hepatectomy found no tumor recurrence.Conclusion:HAML has no specific clinical characteristics or imaging features.The diagnosis of HAML mostly depend on the histopathological examination and hepatectomy is the effective treatment.

This paper described a rapid and se nsitive HPLC method to analyze (E)-3, 5,4'-trimethoxystilbene (BTM-0512) in rat plasma and tissues. The analysis used a BDS Hypersil C18 analytical column (250 mm×4.6 mm ID, 5 μm) and acetonitrile / water as the mobile phase. The UV detection wavelength was 319 nm. Proteins were precipitated with acetonitrile and diethylstilbestrol as internal standard. The method was validated according to State Food and Drug Administration of China and ICH of Technical Requirements for Registration of Pharmaceuticals for Human Use Guidelines. The limit of interday precision values (%RSD) were in the range of 2.6% -5.1% and 2.4% -4.8%, respectively.Mean accuracy and absolute recoveries of BTM-0512 ranged from 95.3% - 100. 1% and 95.9% -100.9% for plasma and tissues, respectively. This method can be quite useful for BTM-0512 pharmacokinetic and tissue distribution studies, for purpose which multiple plasma and tissue samples can be analyzed quickly with high reproducibility.

Objective:To investigate whether hepatitis B virus X protein (HBx) mediates the podocyte injury through reactive oxygen species (ROS) /nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) signaling pathway.Methods:HBx-overexpressing lentivirus was transfected into renal podocytes of mouse to mimic the pathogenesis of hepatitis B virus-associated glomerulonephritis. Podocytes were divided into the following five groups: blank control group (no special treatment), negative control group (transfected with control lentivirus), HBx overexpression group (transfected with HBx overexpression lentivirus), HBx overexpression+NLRP3 siRNA group (transfected with HBx overexpression lentivirus and NLRP3 siRNA), and HBx overexpression+ROS inhibitor group (transfected with HBx overexpression lentivirus and adding ROS inhibitor). The morphological changes of podocytes were observed with electron microscope. The generation of ROS was detected by dichlorodihydrofluorescein diacetate assay (DCFH-DA). Hoechst 33342 staining was used to observe the morphological and quantitative changes of podocyte nuclei. Enzyme-linked immunosorbent assay was used to detect caspase-1 activity, and the levels of lactate dehydrogenase, interleukin (IL)-1β and IL-18. Quantitative real-time polymerase chain reaction and Western blotting were used to detect the expression levels of mRNA and protein of pyroptosis-related protein, such as NLRP3, apoptosis-associated speck-like protein containing card (ASC), caspase-1, IL-1β and IL-18. TUNEL staining and flow cytometer were used to detect the number of pyroptosis cells. Immunofluorescence staining was used to detect the expression levels of desmin and nephrin.Results:After successful infection of podocytes with HBx-overexpressing lentivirus, pyroptosis-related morphological changes in the cells were observed under electron microscope. The level of ROS in the HBx overexpression group was significantly higher compared to the negative control group ( P<0.05). Hoechst 33342 staining revealed condensed nuclei in the HBx overexpression group. TUNEL staining and flow cytometer demonstrated that podocytes underwent increased pyroptosis in the HBx overexpression group. The mRNA and protein expression levels of pyroptosis-related proteins such as NLRP3, ASC, caspase-1, IL-1β and IL-18 were up-regulated upon HBx overexpression (all P<0.05). Caspase-1 enzyme activity, lactate dehydrogenase and desmin expression levels were enhanced after HBx overexpression (all P<0.05). However, NLRP3 knockdown or addition of ROS inhibitors attenuated the pyroptosis and increased expression levels of pyroptosis-related proteins caused by HBx overexpression (all P<0.05). Conclusion:ROS/NLRP3 pathway plays an important role in HBx-induced podocyte pyroptosis.

Objective To introduce the Chinese version of nurse competence scale ( NCS ) for evaluation of clinical nurse competence. Methods The NCS was translated and adapted according to the cross-cultural adaptation process being recommended by the American Association of Orthopaedic Surgeons ( AAOS) Outcomes Committee. Results The internal consistency coefficient of Chinese version scale was 0. 969. The I-CVI of each item was among 0. 83-1. 0. And the S-CVI/Ave was 0. 913. Conclusions The Chinese version of NCS demonstrates good reliability and content validity, but its psychometric properties need further tests.

Objective To explore the clinical effectiveness of emergency upper gastrointestinal bleeding channel for patients with acute upper gastrointestinal bleeding(AUGIB)by the inverse probability of treatment weighted(IPTW)method.Methods A retrospective study method was used.The clinical information was collected on 299 AUGIB patients who belonged to the First People's Hospital of Guiyang,where they were admitted from January 2018 to December 2021.AUGIB patients admitted before the establishment of emergency treatment channel(from January 2018 to December 2019)were selected as the routinel group(152 cases),while AUGIB patients admitted after the establishment of emergency treatment channel(from January 2020 to December 2021)were selected as the channel group(147 cases).IPTW was used to balance multiple confounding variables[gender,age,history of previous underlying diseases,history of non-steroidal anti-inflammatory drug(NSAID)administration,personal history,Glasgow-Blatchford score(GBS),different bleeding etiologies,etc.],a consistent distribution of confounding variables among the groups was achieved after IPTW treatment.The difference of clinical treatment effects between the routine group and the channel group was performed,including time to hemostasis,recurrent bleeding rate,volume of blood transfusions,length of hospital stay,hospitalization cost,intensive care unit(ICU)transfer rate,and mortality etc.were compared.Results After IPTW,the confounding variables were well-balanced between groups.The time to hemostasis[hours:7.90(5.36,11.42)vs.9.92(6.25,18.15)],recurrent bleeding rate[23.1%(34/147)vs.40.1%(61/152)],length of hospital stay[days:8.00(7.00,10.34)vs.9.00(7.00,13.00)],ICU transfer rate[8.8%(13/147)vs.17.7%(27/152)],and mortality[0.7%(1/147)vs.4.5%(7/152)]in channel group were significantly lower than those in the routine group(all P<0.05).There were no significant difference in transfusions volume and hospital cost between channel group and routine group[transfusions volume(U):2(0,4)vs.2(0,4),hospitalization cost(ten thousand yuan):1.35(1.03,2.00)vs.1.16(0.71,2.29),both P>0.05].Conclusion The emergency treatment channel can reduce the recurrent bleeding rate,ICU transfer rate,and mortality rate,shorten the time of hemostasis and length of hospital stay,and has a good treatment effect.
