OBJECTIVE@#To observe preventive effect of Caprini based thrombosis risk evaluation model on venous thromboembolism (VTE) after total knee replacement (TKA).@*METHODS@#Totally 257 TKA patients were admitted from May 2017 to December 2021 were selected. They were divided into conventional intervention strategies (121 patients in control group) and intervention strategies based on Caprini thrombosis risk evaluation model (136 patients in observation group), based on whether Caprini thrombosis risk evaluation model was introduced in May 2019. In normal gourp, there were 79 males and 42 females aged from 50 to 78 years old with an average of (63.10±11.86) years old;body mass index (BMI) ranged from 19 to 32 with an average of (25.21±4.95) kg/m2;55 patients on the left side and 66 on the right side. In observation group, there were 81 males and 55 females aged from 50 to 78 years old with an average of (64.35±10.54) years old;BMI ranged from 19 to 32 with an average of (24.43±5.18) kg/m2;87 patients on the left side and 49 on the right side. The incidence of VTE, visual analogue scale (VAS), Hospital for Special Surgery (HSS) score, affected limb swelling, mean velocity(Vm), peak velocity (PV), D-dimer (D-D), prothrombin time(PT), and incidence of complications were analyzed and compared.@*RESULTS@#The incidence of VTE in observation group was 1.47%(2/136), and 9.09%(11/121) in control group, and there was statistically difference between two groups (χ2=6.976, P=0.008). At 7 days after operation, VAS, HSS score and the difference in circumference of the affected limb in observation group were significantly better than those in control group, and had statistically differences (P<0.05). Blood flow Vm and PV levels between two groups were significantly increased (P<0.001), and blood flow Vm and PV levels in observation group were significantly higher than those in control group on the 7th day after operation, and had differences (P<0.001). The serum D-D level in observation group was significantly lower than that of in control group on the 7th day after operation, and PT level was significantly higher than that of in control group, and had difference(P<0.05). There was no difference in total incidence of complications between two groups (χ2=4.488, P=0.034).@*CONCLUSION@#Intervention strategy based on caprini thrombus risk evluation model could effectively reduce incidence of VTE and complications in TKA patients, improve swelling, hemodynamics and coagulation function of the affected limbs, and contribute to recovery of knee joint function.

It is commonly accepted that females and males differ in their experience of pain. Gender differences have been found in the prevalence and severity of pain in both clinical and animal studies. Sex-related hormones are found to be involved in pain transmission and have critical effects on visceral pain sensitivity. Studies have pointed out the idea that serum estrogen is closely related to visceral nociceptive sensitivity. This review aims to summarize the literature relating to the role of estrogen in modulating visceral pain with emphasis on deciphering the potential central and peripheral mechanisms.

Objective:To investigate the effect of moxibustion at Shenque (CV 8) on free radical metabolism in rat's hippocampus after different degrees of exhaustive exercise.Methods:A total of 72 male Sprague-Dawley (SD) rats were randomly divided into a normal group (n=8),a model group (n=32) and a moxibustion group (n=32).According to the times of modeling or treatment,the model group was further randomly divided into different subgroups of a 1-time model subgroup,a 4-time model subgroup,a 7-time model subgroup and a 10-time model subgroup (n=8);the moxibustion group was also further randomly divided into different subgroups of a 1-time moxibustion subgroup,a 4-time moxibustion subgroup,a 7-time moxibustion subgroup and a 10-time moxibustion subgroup (n=8).Rats in both model and moxibustion subgroups were subjected to establishing the swimming exhaustive model.Rats in each moxibustion subgroup received mild moxibustion at Shenque (CV 8) for 15 min immediately after modeling,once every other day.The concentration of malic dialdehyde (MDA),as well as the activities of superoxide dismutase (SOD),glutathione peroxidase (GSH-Px) and total antioxidant capacity (T-AOC) in rat's hippocampus in each group were detected 24 h after the exhaustive exercise.Results:Compared with the 1-time model subgroup,the exhaustive swimming time of rats was significantly prolonged in the 4-time model subgroup (P<0.01),while it was significantly shortened in the 7-time and 10-time model subgroups (both P<0.01).Compared with the matched model subgroup,the exhaustive swimming time of rats in the 7-time and 10-time moxibustion subgroups was significantly prolonged (both P<0.01).Compared with the normal group,the MDA concentration was increased significantly (P<0.01),and the activities stress response of SOD and T-AOC were increased in the 1-time model subgroup (both P<0.05);the MDA concentration was increased (all P<0.01),and the activities of SOD,GSH-Px and T-AOC were decreased differently (P<0.05 or P<0.01) in the 4-time,7-time and 10-time model subgroups.Compared with the matched model subgroup,the concentration of MDA was significantly reduced (P<0.05 or P<0.01),and the activities of SOD,GSH-Px and T-AOC were significantly increased in the 4-time,7-time and 10-time moxibustion subgroups (all P<0.01).Conclusion:Moxibustion at Shenque (CV 8) can improve the fatigue status of the body after long-term exhaustive exercise by regulating free radical metabolism in rat's hippocampus.To some extent,this provides an experimental basis for moxibustion at Shenque (CV 8) against exercise-induced fatigue.

This study was purposed to investigate the effect of rapamycin on proliferation, apoptosis, cell cycle progression and the regulation of chemokine receptor CXCR4 on RPMI8226 cells. Different concentrations of rapamycin were used to treat the multiple myeloma cell line RPMI8226 for different times. The proliferation of the cells was detected by MTT assay; the apoptosis rate and cell cycle were determined by flow cytometry (FCM); apoptosis of cells was observed by inverted microscopy; the cylin D1, CXCR4 and mTOR mRNA expressions were detected by RT-PCR or FQ-PCR after treating RPMI8226 cells with different concentrations of rapamycin. The results indicated that the rapamycin could inhibit the proliferation of RPMI8226 cells and induce their apoptosis. The cell cycle was arrested at the G(0)/G(1) phase. PCR results showed the down-regulation of mTOR, cyclin D1 and mTOR mRNA expressions after treating RPMI8226 cells with different concentrations of rapamycin for 24 hours. It is concluded that the rapamycin significantly inhibits the growth of RPMI8226 cells in a dose-and time-dependent mannes and induce cell apoptosis. Cell cycle arrests at the G(0)/G(1) phase, may be due to the down-regulation of the mTOR and cyclin D1 expressions. In additions, the down-regulation of CXCR4 mRNA expression is correlated with the reduction of adhesion between myeloma cells and stromal cells.

<p><b>OBJECTIVE</b>To assess the efficacy of a nasally inhaled corticosteroid (ICS) through a spacer with mask aiming at simultaneous treatment of allergic rhinitis and asthma in children and make an analysis on the costs.</p><p><b>METHOD</b>A total of 72 children with allergic rhinitis (AR) and asthma were randomized into two groups. Experimental group received budesonide inhaler (400 microg/d) through the nose using a spacer attached to a face mask, control group children orally inhaled budesonide dry powder (400 microg/d) plus a nasal spray of budesonide aquae (256 microg/d).</p><p><b>RESULT</b>The patients were observed for 12 weeks. The symptom scores of rhinitis of both experimental group and control group declined (F=6.529 and 7.014, all P<0.01), symptom scores of asthma in both group were also reduced (F=4.132 and 4.950, P<0.01). The pulmonary function PEF (L/min) in both groups continuously increased (F=2.750 and 3.282, P<0.05). But the clinical scores, PEF value and FEV1 all did not differ between the two groups at admission or at nearly all follow-up visits (P>0.05 for all). The proportion of dry nose was lower in experimental group than in the control group (5.6% vs. 19.4%), but the difference was not statistically significant. The cost in the experimental group was lower than that in the control group (P<0.01).</p><p><b>CONCLUSION</b>Nasal inhalation of ICS provides a therapeutic strategy for controlling AR and asthma in children, especially it result in higher compliance, lower costs, and fewer side effects.</p>

<p><b>OBJECTIVE</b>To compare the effects of inhaled corticosteroids (ICS) and oral leukotriene modifier (LTM) montelukast on the prognosis of children with cough variant asthma (CVA), and to identify the related risk factors for the development of classic asthma in children with CVA.</p><p><b>METHODS</b>Eighty-four children with CVA (2 - 6 yrs) were randomized to receive inhaled beclomethasone dipropionate 200 microg/d through pressurized metered-dose inhaler (MDI) plus spacer with mask or oral montelukast 5 mg, once at bedtime for 6 months, then followed by 18 months observation period after the end of the study medication.</p><p><b>RESULTS</b>There was no significant difference in antitussive days between the two groups (ICS group: 14 +/- 9 days, LTM group: 13 +/- 9 days, Z = 1.12, P = 0.25). Wheezing developed in 7.1% of the children in ICS group during 24 months follow-up period, which was significantly lower than that in LTM group (33.3%, chi2 = 8.92, P = 0.003). The prevalence of eczema or allergic rhinitis was higher in children who developed wheezing than those who did not develop wheezing (eczema: 47.1% vs. 19.4%, chi(2) = 4.16, P = 0.042; allergic rhinitis: 58.8% vs. 31.3%, chi2 = 4.40, P = 0.036). Logistic regression analysis confirmed that eczema and allergic rhinitis were risk factors for wheezing development in children with CVA, the odds ratio was 7.668 and 3.855 respectively (P < 0.05 for all). But administration of ICS was negatively correlated with the development of wheezing by an odds ratio of 0.128 (P = 0.008).</p><p><b>CONCLUSIONS</b>Children with CVA may progress to classic asthma; eczema and allergic rhinitis are two risk factors for wheezing development in children with CVA. Both ICS and LTM are effective antitussive treatment, but ICS may be more effective than LTM on preventing the progression of CVA to classic asthma.</p>

<p><b>OBJECTIVE</b>To observe the effect of artemisinin on the ischemia/reperfusion injury of the iisolated rat myocardium and to preliminarily study the possible mechanism.</p><p><b>METHOD</b>Fifty Wistar rats were randomly divided into 5 groups: a control group, an ischemia/reperfusion (I/R) group, and 3 artemisinin (AS) groups (10, 100, 1000 micromol x L(-1)), 10 rats in each group. Ischemia/reperfusion injury of the isolated rat myocardium was induced by a Langendorff system. The electrocardiogram, the cardiac functional parameters, coronary flow, and the activities of LDH (lactate dehydrogenase), CPK (creatine phosphokinase), SOD (superoxide dis-mutase) and the level of malondiadehyde (MDA) in myocardial tissue, and the myocardial ultrastructures were investigated.</p><p><b>RESULT</b>AS (10,100 micromol x L(-1)) could significantly improve the index of the myocardial function (+/- dp/dt(max), LVSP) after the ischemia/reperfusion, increase the coronary flow, decrease the leakage of LDH and CPK, and increase the SOD activity and decrease the MDA level in cardiac tissues, and alleviate the myocardial ultrastructure injury. But, AS (1000 micromo x L(-1)) did not have the above effects.</p><p><b>CONCLUSION</b>AS (10, 100 micromol x L(-1)) alleviate the myocardial ischemia/reperfusion injury in rats. The mechanism may be related to its functions of antioxidation and scavenging free radicals.</p>
