Objective The aim of this research is to evaluate the influence of nursing intervention on the compliance of patients with dysfunctional uterine bleeding in climacteric period. Methods We divided 96 patients with dysfunctional uterine bleeding in climacteric period from February to December in 2006 into the intervention group and the control group with 48 cases in each group.The control group was given medication instruction simply by the doctors and no nursing intervention.The intervention group was given health education and follow-up supervision.The general information and medical history of patients were registered at the first visit. The medication, adverse effect and effect of drugs were also registered at every visit. All patients were given follow-up visit 3 months later.The medication and visiting compliance and the treatment effect were observed. Results One patients missed follow-up visit in the intervention group and 11 patients missed in the control group.The medication compliance was 87.2% and the visit compliance was 93.6% in the intervention group,which was superior to those of the control group (67.6%,56.8%).The effect of hormone treatment was also better than that of the control group,P ＜ 0.05. Conclusions Nursing intervention couhl improve the compliance and medication effect of patients with dysfunctional uterine bleeding in climacteric period.

OBJECTIVE: To study the therapeutic mechanism of salvianolic acid B (SA-B) in treating hepatic fibrosis. METHODS: Twenty-four Wistar rats were randomly divided into 3 groups: normal control group, untreated group and SA-B-treated group. Rats in the untreated and SA-B-treated groups were injected intraperitoneally with 0.5% dimethylnitrosamine (DMN) for 4 weeks, daily for 3 days each week at a dose of 10 microg/kg, to induce hepatic fibrosis. Then, rats in the SA-B-treated group were given SA-B orally for another 4 weeks. Hydroxyproline (Hyp) contents in liver tissue of the rats in 3 groups were determined with HCl hydrolysis, and collagen type I, transforming growth factor-beta 1 (TGF-beta1), transforming growth factor-beta receptor type I (TbetaRI) and transforming growth factor-beta receptor type II (TbetaRII) were detected by Western blotting. RESULTS: The Hyp content and the expressions of collagen type I, TGF-beta1, TbetaRI and TbetaRII in the liver tissue of rats in the untreated group increased significantly as compared with those in the normal control group, while those in SA-B-treated group decreased significantly as compared with those in the untreated group. CONCLUSION: The therapeutic mechanism of SA-B in treating hepatic fibrosis may be related to inhibiting the expressions of TGF-beta1 and its receptors.

Policy background and stakeholder theory were elaborated.It could be concluded that the key stakeholders of the policy were residents,training hospitals,healthcare administrators,primary healthcare institutions and patients of such institutions.Through analysis of these stakeholders,effects on the interests of all parties were investigated and strategies to improve feasibility of the policy were put forward.Two key points were suggested for such policy goals.First,top-level policies should be designed and be effectively implemented.Second,conversion of the residents from permanent hospital employees to “contractors”or“ freelancers”.

Objective To analyze the feasibility of the policy that “Residents service or employment at primary care institutions after standardized training”.Methods Analyzing the feasibility of this policy by using questionnaire survey and in-depth interview.Results Constituent ratios of overall feasibility were 58.3％ (532/912)and 66.1％(603/912)for specialist and general practitioner respectively; percentage of feasibility of in-depth interview was 46.7％ (7/15).Conclusion The policy has feasibility,if government formulates and implements perfect complement policies effectively,and makes this policy to be impassable stage to resident.

Objective To compare the outcomes of homeopathic bidirectional-traction reduction device and traction table in surgical treatment of femoral intertrochanteric fractures.Methods A retrospective case control study was made on 94 cases of femoral intertrochanteric fractures treated from July 2015 to December 2015.There were 26 males and 68 females,aged 60-75 years.According to the Evans classification,the fractures were type Ⅱ in 24 cases,type Ⅲ in 32 and type Ⅳ in 38.Fifty-seven cases sustained chronic diseases.According to the random number table,the subjects were assigned to receive homeopathic bidirectional-traction reduction (homeopathic reduction group,48 cases) and traction table reduction (control group,46 cases).All fractures were fixed with proximal femoral nail antirotation.Operation time,reduction time,tluoroscopy time,blood loss and rate of closed reduced cases were recorded.Fracture union and rotation of the affected femur to the tibia were detected after operation.Functional outcome was evaluated using the Harris score at the final follow-up.Results All fractures were reduced closely in homeopathic reduction group,while 15 fractures in control group were reduced via a small-incision anterior approach.Operation time,reduction time and fluoroscopy time in homeopathic reduction group were (62.9 ± 12.1) min,(6.8 ± 1.5) min and (11.3 ± 5.6) s respectively,significantly less than the corresponding data in control group (all P ＜ 0.05).One month after operation,rotation of the affected femur to the tibia was (2.8 ± 1.2) ° in homeopathic reduction group,significantly less than that in control group [(11.5 ± 4.7) °] (P ＜ 0.05).Bone union was observed in all cases.At the final follow-up,Harris hip score was (92.6 ± 7.6)points in homeopathic reduction group,significantly higher than that in control group [(87.3 ± 6.5) points] (P ＜ 0.05).Conclusion For the elderly patients with intertrochanteric fractures,homeopathic bidirectional-traction device has advantages of high rate of closed reduction,shorter operation time,less radiological exposure and satisfactory function recovery of the affected hip joint.

Predicting the protein binding rate of drugs in plasma is helpful to us in understanding the pharmacokinetic characteristics of drugs, with much value of reference for early research on drug discovery. In this study, plasma protein binding rate information of 2 452 clinical drugs were collected.Two pieces of software, Molecular Operating Environment (MOE) and Mordred, were used to calculate molecular descriptors, which were used as input features of the model.Extreme gradient boosting (XGBoost) algorithm and random forest (RF) algorithm were then used to build a machine learning model.The results showed that, compared with MOE, the prediction performance of the constructed model was better using the molecular descriptor calculated by Mordred as the input of the model.The prediction performance results of the model constructed using the XGBoost algorithm and the RF algorithm were similar, and the R2 of the optimal model were both 0.715.According to the research results, it can be concluded that the drug plasma protein binding rate is closely related to some physical and chemical properties of the drug molecule, such as water solubility, octanol/water partition coefficient and conjugated double bonds.Using these parameters to predict the plasma protein binding rate of drugs has the advantages of convenience and efficiency, which can provide reference for related pharmacokinetic studies.

ObjectiveTo study the effect of Bushen Huoxuetang on the apoptosis and the expression of B-cell lymphoma （Bcl-2）-associated X protein （Bax）/ Bcl-2 and cleaved cysteine-containing aspartate proteolytic enzyme-3 （cleaved Caspase-3） in the nude mouse model of bone metastasis of breast cancer， and explore the mechanism of Bushen Huoxuetang in inhibiting bone destruction. MethodThirty BALB/c female nude mice were randomly assigned into blank group （n=6） and model group （n=24）. The suspension of 4T1 breast cancer cells was injected into the tibia of mouse right lower limb to establish model of bone metastasis of breast cancer. The successfully modeled nude mice were randomly assigned into model group， Bushen Huoxuetang group， zoledronic acid group， and combined drug group， with 6 mice in each group. Bushen Huoxuetang was administrated at a dose of 36.67 g·kg^-1， once a day， and zoledronic acid was administrated by subcutaneous injection at a dose of 100 μg·kg^-1， twice a week. The combined drug group was administrated with the same doses of Bushen Huoxuetang group by gavage and zoledronic acid by subcutaneous injection. The mice in the blank group and the model group were administrated with the same volume of distilled water by gavage for 14 days. On the next day at the end of drug administration， the mice were sacrificed by cervical dislocation. The general situation and weight changes of the mice were examined. The right lower limb was collected， and X-ray scanning and hematoxylin-eosin （HE） staining methods were used for observation of pathological changes in the bone. The terminal deoxynucleotidyl transferase dUTP nick-end labeling （TUNEL） was employed to detect the apoptosis of bone tissue in nude mice， and Western blot to determine the expression of Bax/Bcl-2 and cleaved Caspase-3 in the bone tissue. ResultCompared with the blank group， the modeling reduced the body weight （P<0.01） and increased the right lower limb weight of the nude mice （P<0.01）. Compared with the model group， Bushen Huoxuetang， zoledronic acid， and their combination increased the body weight （P<0.01） and decreased the right lower limb weight （P<0.01）. Compared with the blank group， the other groups showed obvious tumor cell atypia， deep nuclear staining， and clear bone metastasis， and the model group showed obvious osteolytic damage in right lower limb and loss of proximal tibia and knee joint. Compared with the model group， Bushen Huoxuetang， zoledronic acid， and their combination reduced the osteolytic lesions in the right lower limb and recovered part of the bone structure， demonstrating an inhibitory effect on bone destruction. The TUNEL assay showed that the model group had lower apoptosis rate of bone metastatic tumor cells than the blank group， Bushen Huoxuetang group， zoledronic acid group， and combined drug group （P<0.01）. Compared with the blank group， the modeling down-regulated the expression of Bax and cleaved Caspase-3 （P<0.01） and up-regulated the expression of Bcl-2 （P<0.01）. Compared with the model group， Bushen Huoxuetang， zoledronic acid， and their combination up-regulated the expression of Bax （P<0.01） and cleaved Caspase-3 （P<0.05， P<0.01） and down-regulated the expression of Bcl-2 （P<0.05， P<0.01）. ConclusionBushen Huoxuetang may inhibit bone destruction in the nude mouse model of bone metastasis of breast cancer by up-regulating the expression of Bax， down-regulating the expression of Bcl-2， activating cleaved Caspase-3， and further inducing apoptosis.

Objective: To construct and determine the weight of Index System for Assessing Parent s Ability on Child Injury Prevention, and to provide the basis for childhood injury intervention in family. Methods: Twenty four experts majored in related fields were invited to participate in Delphi consultation. The final index system was constructed according to the consulting results and the weight of primary and secondary indicators were calculated. Results: The final index system consisted of 5 subscales corresponding to 5 age groups: 0,1-2,3-5,6-11 and 12-17 years old. Each scale included 4 primary indicators and 11 secondary indicators. The weight of primary indicators obtained by analytic hierarchy process is 0.28 for "environment", 0.16 for "product", 0.31 for "behaviors and skills", and 0.25 for "psychology". The highest weight of secondary indicators for "environment", "product" and "behaviors and skills" was "water area", while the top secondary indicators for "psychology" included "parental style""emotional control" "family atmosphere", with all indicators weighted higher than 0.2. Conclusion The Index System for Assessing Parent s Ability on Child Injury Prevention by Delphi consultation is comprehensive in content, and with the focus on parental behaviors and skills on injury prevention.

Objective: To investigate child injury prevention practice and associated factors among parents of primary school students. Methods: Parents of 2 577 students were selected from three primary schools in three administrative regions of Shanghai by multi stage sampling method between May and June in 2021. Questionnaire survey was administered to parents based on the Index System for Assessing Parent s Ability on Child Injury Prevention, which was developed previously by the present research group. Results were converted into standardized scores for descriptive analysis, and the original scores were analyzed by multiple linear regression model. Results: The standardized scores of parents on environment safety, product safety, behaviors and skills and psychological safety were (0.91±0.08)(0.93±0.08)(0.97±0.04)(0.95±0.05), respectively. The standardized score of general ability was (0.95±0.04). The standardized scores on knowledge, attitude and practice of injury prevention were (0.99±0.03)( 0.97± 0.05)(0.89±0.10), respectively. Mothers performances were generally better than fathers . Parents with higher education performed better than those with lower education. Parents with "being a parent" in mind performed better on child injury prevention. Conclusion There is a gap between practice with the knowledge as well as attitude towards child injury prevention among parents of primary school students. Parenting role, educational background and parental awareness of the importance of parental role are primary factors that affect child injury prevention practice.
