In order to find new cephalosporin with more and more potent antibacterial activity, nine new fourth-generation cephalosporins (N1-N9) were synthesized from ethyl 2-(2-aminothiazol-4-yl)-(Z)-2-methoxyiminoacetate (1) via acylation, substitution, hydrolysis, active esterification, condensation and salt formation. The structures of compounds (N1-N9) were confirmed by IR, MS, 1H NMR and elemental analysis. The target compounds possess different antimicrobial activities against Gram-positive and Gram-negative bacteria. The preliminary results of antibacterial activities revealed that they showed better antibacterial activities against Gram-positive bacteria than cefpirome sulfate. In particular, their activities against Staphylococcus aureus and Streptococcus albus are better.

BACKGROUND:The risk of lower extremity deep venous thrombosis was high in patients with bone metastases. Major surgery is a major risk factor for thrombosis. There was no standard prophylactic regimen available.
OBJECTIVE:To investigate the efficacy and safety of low molecular weight heparins versus rivaroxaban in the postoperative prevention of lower extremity deep venous thrombosis in patients with bone metastases.
METHODS:From January 2010 to December 2013, a total of 73 patients with bone metastasis in spine, pelvis and lower extremities, who underwent open surgery in the Department of Musculoskeletal Tumor, Third Hospital, Hebei Medical University, China, were retrospectively analyzed. The patients were divided into low molecular weight heparins group (n=41) and rivaroxaban group (n=32) according to the prophylactic drugs after surgery.
RESULTS AND CONCLUSION:Nine cases (22%) in the low molecular weight heparins group were found lower extremity deep venous thrombosis, and six cases (19%) in the rivaroxaban group suffered from lower extremity deep venous thrombosis, showing no significant differences (χ2=0.11, P=0.74). The incidences of bleeding events in both groups were respectively 7.32%and 6.25%, showing no significant differences (correctionχ2=0.083, P>0.05). There were no significant differences regarding the levels of platelet, activated partial thromboplastin time and prothrombin time between both groups preoperatively or postoperatively (P>0.05). Therefore, the efficacy and safety of low molecular weight heparins and rivaroxaban in the postoperative prevention of lower extremity deep venous thrombosis were similar. Both could effectively reduce the incidence of deep venous thrombosis, with a relative low risk of bleeding.

To study photosynthetic characteristics and its influencing factors in leaves of medicinal plant Mirabilis himalaica, and provide an evidence for guiding artificial planting and improving the quantity. The light-response and diurnal photosynthesis course of leaves at the booting stages of 1-3 year old M. himalaica were measured with LI-6400 system. The Results showed that the light response curves were fitted well by non rectangle hyperbola equation (R2 > or = 0.98). The values of the maximum photosynthetic rate (Pmax) and light use efficiency of three-year old M. himalaica leaves were higher than those of 1-2 year old individuals. The diurnal variation of net photosynthetic rate (Pn) and stomatal conductance (Gs) of 2-3 year old M. himalaica were typical double-peak curves determinately regulated by stomatal conductance. However, transpiration rate (Tr) of 1-3 year old plants leaves were single-peak curve, which was self-protection of harm reduction caused by the higher temperature at noontime. Correlation analysis showed that the changes between photosynthetic active radiation (PFD), air temperature (T ) and Pn, were significant positive related. Therefore, M. himalaica is a typical sun plant, which should be planted under the sufficient sunshine field and prolong the growing ages suitably in order to improve the yield.

Objective: To observe the clinical effects of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) in the treatment of shoulder and arm pain. Methods: A total of 90 patients with shoulder and arm pain were randomly divided into an observation group and a control group, 45 cases in each group. The treatment of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) was adopted in the observation group, routine acupuncture was used in the control group. The two groups were treated once every day, with 5 treatments as one course, and a 2-day rest between two courses. After 3 courses, pain was assessed by visual analog scale (VAS), and the clinical effects were compared between the two groups. Results: After the treatment, VAS scores were significantly changed in both groups (both P<0.01). The VAS score was lower in the observation group than that in the control group, with a statistical difference between the two groups (P<0.05). The total effective rate was 100% in the observation group, versus 91.1% in the control group, the difference was statistically significant (P<0.05). Conclusion: The therapeutic effect of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) is better than that of routine acupuncture in treating shoulder and arm pain.

Objective To discuss the frequent etiology of spontaneous sub-cortical hemorrhage and its diag- nosis.Methods The clinical materials of 79 cases of spontaneous sub-cortical hemorrhage were analyzed.Results 56% of the hemorrhage was caused by arterial-venous malformation.48% of the hemorrhage was caused by occult AVM.Conclusion AVM is the most frequent etiology of spontaneous sub-cortical hemorrhage.CTA plays a special role in its diagnosis.

Objective:To investigate the predictive value of circulating miR-143 and miR-182 for the short-term clinical outcomes in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to Danzhou People's Hospital from January 2018 to June 2020 were included prospectively. The modified Rankin Scale was used to evaluate the short-term clinical outcome at 14 d after onset or at discharge. 0-2 was defined as good outcome, and >2 was defined as poor outcome. Multivariate logistic regression analysis was used to identify the independent risk factors for poor short-term clinical outcomes in patients with AIS. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of miR-143 and miR-182 for the short-term clinical outcomes in patients with AIS. Results:A total of 158 patients with AIS, aged 65.80±12.36 years, were enrolled, including 105 males (66.46%), 95 patients with good outcome (60.1%) and 63 with poor outcome (39.9%). The age, total cholesterol, triglyceride, low-density lipoprotein cholesterol, baseline National Institutes of Health Stroke Scale (NIHSS) score, serum miR-143 and miR-182 level in the poor outcome group were significantly higher than those in the good outcome group (all P<0.05). Multivariate logistic regression analysis showed that age (odds ratio [ OR] 1.984, 95% confidence interval [ CI] 1.315-3.617; P=0.036), low-density lipoprotein cholesterol ( OR 2.108, 95% CI 1.406-4.103; P=0.013), baseline NIHSS score ( OR 2.584, 95% CI 1.675-4.505; P=0.005), miR-143 ( OR 3.205, 95% CI 2.370-6.180; P<0.001) and miR-182 ( OR 2.802, 95% CI 1.905-5.516; P<0.001) were the independent risk factors for poor outcomes in patients with AIS. ROC curve analysis showed that the combined area under the curve of miR-143 and miR-182 to predict the poor outcome in patients with AIS was 0.935 (95% CI 0.873-0.992), the sensitivity and specificity were 96.5% and 87.0% respectively. Conclusions:The increase of serum miR-143 and miR-182 was closely associated with the poor short-term outcomes in patients with AIS. The combination of the two has a good predictive value for the poor short-term outcomes in patients with AIS.
