OBJECTIVE:To compare the clinical efficacy and safety of rivaroxaban and low molecular weight heparin calcium (LMWHA)in the prevention of deep venous thrombosis(DVT)after total hip arthroplasty(THA). METHODS:A total of 100 THA patients selected from orthopedics department of our hospital as research objects were divided into control group and observa-tion group according to random number table,with 50 cases in each group. Control group was treated with LMWHA injection 0.4 mL subcutaneously,qd;observation group was given Rivaroxaban tablet 10 mg orally,qd. Both groups received treatment on the first day after surgery,for consecutive 14 d. Coagulation indexes(PT,APTT,Fib,TT,D-D),VAS score,the incidence of DVT and PE were observed in 2 groups. The postoperative bleeding volume and ADR as hematoma and gastrointestinal bleeding were compared between 2 groups. RESULTS:Before treatment,there was no statistical significance in coagulation indexes or VAS scores between 2 groups(P>0.05). After treatment,PT,APTT,TT and D-D levels,VAS scores of 2 groups were decreased sig-nificantly,while Fib levels were increased significantly;VAS score of observation group was significantly lower than that of con-trol group,with statistical significance(P<0.05). There was no statistical significance in coagulation indexes between 2 groups (P>0.05). The incidence of DVT and PE in observation group were 8.00% and 7.50% ,which were significantly lower than 12.00% and 4.00% of control group,with no statistical significance(P>0.05). The postoperative bleeding volume of observation group was(298.31±52.18)mL,which was significantly lower than(327.40±54.20)mL of control group,with statistical signifi-cance(P<0.05). There was no statistical significance in the incidence of hematoma or gastrointestinal bleeding between 2 groups (P>0.05). CONCLUSIONS:Rivaroxaban and LMWHA can significantly improve coagulation state,prevent the generation of DVT after THA. While rivaroxaban is better in shortening pain time without increasing the risk of ADR.

OBJECTIVE:To explore the clinical effect and safety of Zoledronic acid injection combined with percutaneous ver-tebroplasty for osteoporotic vertebral compression fracture(OVCF). METHODS:A total of 130 OVCF patients selected from our hospital during Jan. 2014-Dec. 2015 were divided into observation group and control group according to random number table,with 65 cases in each group. Control group was given bone cement by percutaneous vertebroplasty. Observation group was additionally given Zoledronic acid injection 5 mg,ivgtt,once a year(dripping time ≥15 min),on the basis of control group. Both groups were given calcium and vitamin D orally after surgery. VAS scores,Oswestry disability index(ODI)and ADL scores were ob-served in 2 groups 1 week and 6 months after treatment. Bone density of lumbar vertebra L1-L4 and femoral neck were detected in 2 groups after one year of treatment. RESULTS:Before treatment,there was no statistical significance in VAS scores,ODI or ADL scores,bone density of lumbar vertebra LI-L4 and femoral neck between 2 groups(P>0.05). VAS scores and ODI of 2 groups were decreased significantly,while ADL scores were increased significantly 1 week and 6 months after treatment;obser-vation group were significantly better than control group,with statistical significance(P<0.05). One year after treatment,bone density of lumbar vertebra L1-L4 and femoral neck in observation group were significantly higher than control group,with statis-tical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups as fever,dizziness, bone and joint pain,muscle soft tissue pain and new fracture(P>0.05). CONCLUSIONS:Zoledronic acid combined with per-cutaneous vertebroplasty in the treatment of OVCF can significantly relieve pain,improve dysfunction and enhance bone density with good safety.

In gynecology, it is very important to obtain the parameters of women's uterine musculature, such as its deformation size and contraction frequency, etc. This paper proposes a type of sensor for measuring these parameters and also analyzes its force situation. The sensor is flexible, deformable, and can adjust itself to the shape of the uterus. It can be put into the women's uterine cavity easily. The experiment shows that the sensitivity of the left and right sets coils of the sample sensor achieves 22.38 nH/mm2, while that of the top set coils achieves 22.84 nH/mm2, and the reaction time of the sensor is less than 200 ms. These results can meet the requirements of sensitivity and reaction time for testing the contraction situation of uterine musculature. The sensor has been applied in some medical fields.

Objective:To explore the effect of moderate intensity physical exercise on depression, anxiety and cognitive function of schizophrenic patients and its possible biochemical mechanism.Methods:Totally 148 patients with schizophrenia who were hospitalized in hospital from March 2019 to March 2021 were randomly divided into control group ( n=75) and exercise group ( n=73). The patients of the two groups were given drug treatment and routine exercise according to clinical practice, and the patients in exercise group were given additional medium-intensity physical exercise.Self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to evaluate the poor mental state of the subjects.The verbal fluency task(VFT), digital span test(DST), trail making test-A(TMT-A) and the positive and negative symptom scale (PANSS) were used to evaluate cognitive function.The levels of endocannabinoids (eCBs) receptors were detected by high performance liquid chromatography, and the levels of monoamine neurotransmitters and eCBs in the patients' serum were determined by enzyme-linked immunosorbent assay (ELISA). SPSS 19.0 software was used for statistical analysis.The measurement data between the two groups were compared by t-test and the counting data between the two groups were compared by χ2 test. Results:(1) After effective intervention, the scores of SAS, SDS, TMT-A and PANSS of the two groups were significantly lower than those before intervention, and the difference before and after intervention between the two groups was statistically significant( t=6.00, 6.52, 25.79, 17.03, all P<0.01). The scores of SAS, SDS, TMT-A and PANSS after intervention in the exercise group were significantly lower than those in the control group( t=4.66, 20.88, 6.61, 8.95; all P<0.01). The number of VFT and DST in the two groups after intervention were significantly higher than those before intervention, and the differences before and after intervention between the two groups were statistically significant( t=13.78, 22.76, both P<0.01). After effective intervention, the number of VFT and DST in exercise group were significantly higher than those in the control group( t=5.02, 5.15, both P<0.01). (2) After effective intervention, the contents of monoamine neurotransmitters and eCBs in serum of the two groups were significantly higher than those before intervention, and HVA level ((63.68±6.99) pg/mL), MHPG level ((175.90±16.22) pg/mL), 5-HIAA level ((29.94±4.19) pg/mL) and CBR1 level ((6.70±1.40)μg/L), 2-AG level ((61.90±5.73)pmol/g) and AEA level ((76.48±6.59) pmol/g) in exercise group were significantly higher than those in the control group ((52.97±5.37)pg/mL, (138.50±11.52)pg/mL, (23.87±3.15)pg/mL, (5.71±1.29)μg/L, (52.13±5.14)pmol/g, (67.66±5.88)pmol/g)( t=10.43, 16.21, 10.91, 8.65, all P<0.01). Conclusion:Moderate intensity physical exercise can significantly improve their depression, anxiety and cognitive function, which may be related to regulating the levels of ECBS and their receptors in patients with chronic schizophrenia to increase monoamine neurotransmitters.
