ObjectiveTo study the neuron protection mechanism of Uncariae Ramulus Cum Uncis extract for the MPTP-induced PD mice.MethodsC57BL/6 mice were randomly divided into control group, model group, Uncariae Ramulus Cum Uncis extract group and madopar group, and injected with MPTP in abdominal cavity. Behavior test was used to detect grabbing capacity and body movement coordination capacity: three biochemical indexes (SOD, MDA, GSH-Px) were detected by biochemical process and the activity of two immune enzyme-linked indexes (IL-1β, IL-6) were detected by enzymelinked immunosorbent assay.ResultsCompared with the control group, the autonomic activity numbers of mice increased and climbing pole time decreased in the model group (P<0.05), enzymatic activity of SOD and GSH-Px decreased significantly and the contents of MDA, IL-1β and IL-6 increased obviously (P<0.01). Compared with model group, the autonomic activity numbers of mice increased and climbing pole time decreased in the Uncariae Ramulus Cum Uncis extract group and madopar group (P<0.05). Enzymatic activity of SOD and GSH-Px increased and the contents of MDA and IL-1β and IL-6 decreased (P<0.05,P<0.01).ConclusionUncariae Ramulus Cum Uncis extract can reduce neuronic apoptosis PD mice, whose therapeutic action may be realized through eliminating oxygen free radicals, improving oxidation resistance and reducing inflammatory reactions.

Objective To optimize the prescription ofBaichanting Tablets by the central composite design-response surface methodology.Methods The doses of MCC, cCMC-Na, SiO2, and magnesium stearate were set as investigation factors; disintegration time and moisture rate were set as indexes. Linear equation quadratic polynomial described mathematic relationship of disintegration time and moisture rate with other four influence factors. Response surface was described according to the optimal mathematic models; the optimal prescription was chosen; predictive analysis was conducted.ResultsThe relationship of disintegration time and moisture rate with other four influence factors could not be described by linear equation. When quadratic polynomial matching was used, correlation coefficients were 0.837 9 and 0.923 1, with relatively high reliability. Optimal prescription contained 30.6%MCC, 10%cCMC-Na, 0.30%SiO2, and 0.10% magnesium stearate. The theoretical value and predicted value deviations of the disintegration time limit and moisture absorption rate were within 5%.Conclusion The predictability of the established model is good. Application of central composite design-response surface methodology can precisely optimize the prescription ofBaichanting Tablets.

Objective To investigate the prognostic values of serum lactate dehydrogenase(LDH) and beta-2 microglobulin(?2-MG) levels in patients with acute myeloid leukemia(AML). Methods The associations of serum LDH and ?2-MG levels at diagnosis,remission and relapse with treatment and prognosis in 68 patients with AML were retrospectively analysed. Results There were no difference in LDH and ?2-MG between AML subtypes patients.The level of serum LDH and ?2-MG at diagnosis and relapse were much higher than those at remission.Patients with lower level of LDH and ?2-MG got higher CR rate and longer term overall survival and disease-free survival.Patients with higher level of both LDH and ?2-MG got lower CR rate,shorter term of overall survival and disease-free survival than those with higher level of LDH or ?2-MG or those with normal level of LDH and ?2-MG. Conclusion LDH and ?2-MG is a singificant prognostic indicator for AML.While combined LDH and ?2-MG are more definite for the treatment and diagnosis.

Objective To study the effective composition of Aster ageratoides Turcz for relieving asthma and its toxicity . Methods Seventy‐two qualified male guinea pigs ,body mass(300 ± 20)g ,were randomly divided into the control group ,aminophyl‐line group(0 .047 g/kg) and different ratio group of total saponins and total flavonoids (8∶1 ,4∶1 ,2∶1 ,1∶1 ,1∶2 ,1∶4 ,1∶8) . Every group received at dose of 0 .38 g/kg once a day for 3 days by intragastric administration .The effect of relieving asthma was taken as the indicators for the optimization of compositions ,which was detected by observing the latent period of asthma induced by acetylcholine‐histamine in guinea rats .The relaxation percentage of smooth muscle retracted by acetylcholine was detected by Pow‐erlab biological signal collecting system when aminophylline(1 .25 mg/mL) and different matching drugs(0 .02 g/mL) were added in Krebs′solution .The acute toxicities of total saponins ,total flavonoids and mixture of total saponins with total flavonoids (ratio of 1∶2) were detected by classical acute toxicity test of mice .Results Compared with the control group ,aminophylline group ,each group latent period of inducing asthma significantly or very significantly prolonged (P<0 .05) ,among them ,1∶1 ,1∶2 ,1∶4 group and other matching group were significantly different(P<0 .05) ,but 1∶2 group cited the longest incubation period .Aminophylline group and the ratio could significantly relaxe guinea pig tracheal smooth muscle retracted by acetylcholine .Aminophylline group di‐astolic percentage was the largest(24 .12 ± 1 .20)% ,all the groups were less than the percentage of diastolic aminophylline group (P<0 .05) ,but in 1∶2 group with the closest .Aster ageratoides Turcz ,tatarian aster total saponins ,total flavonoids and the ratio of 1∶2 to mice maximum tolerance was respectively 300 ,345 ,325 g/kg .Conclusion For the same total dosage ,the relieving asth‐ma effects of proportions of 1∶2 Aster ageratoides Turcz were obvious .There are no abnormal changes in the acute toxicity trila with total flavonoids ,total saponins ,as well as the ratio of 1∶2 ,safety is relatively good .

Abstract: Objective To understand the distribution and drug resistance of bacteria in clinical blood culture specimens in Ningxia in recent years, and to provide a basis for the prevention and treatment of bloodstream infection diseases. Methods The blood culture isolation bacteria and drug resistance of Ningxia bacterial resistance monitoring network hospitals from 2018 to 2020 were statistically analyzed by WHONET5.6 software. Results In the past three years, a total of 6 757 strains of bacteria were isolated from blood samples, including 3 697 strains (54.7%) of gram-negative bacteria and 3 060 (45.3%) of gram-positive bacteria. Among the gram-negative bacteria, Escherichia coli (2 074 strains,30.7%), Klebsiella pneumoniae (696 strains), Pseudomonas aeruginosa (139 strains), and Acinetobacter baumannii (121 strains). Among the gram-positive bacteria, coagulase-negative Staphylococcus (1 691 strains,25.0%), Staphylococcus aureus (442 strains), Streptococcus spp. (431 strains), Enterococcus spp. (379 strains). Resistance to Escherichia coli and Klebsiella pneumoniae was 56.6% and 22.6% against third-generation cephalosporins, and resistance to carbapenems was 1.0% and 3.7%, respectively. Pseudomonas aeruginosa and Acinetobacter baumannii were resistant to carbapenems at 9.0%(12/139) and 80.7%(71/121). Methicillin-resistant Staphylococcus aureus (MRSA) was detected at 26.8%, methicillin-resistant coagulase-negative Staphylococcus was detected at 70%, and no Staphylococcus bacteria resistant to vancomycin and linezolid were found. For three years, only 1 strain of vancomycin-resistant Enterococcus faecalis was detected, and no linezolid-resistant Staphylococcus and Enterococcus were detected. Conclusions Ningxia clinical blood specimen isolates of Escherichia coli, coagulase-negative Staphylococcus, and Klebsiella pneumoniae are more common. Among them, the resistance rate of Escherichia coli and Klebsiella pneumoniae to the third generation of cephalosporins is relatively stable, and the resistance rate to carbapenems is low. Acinetobacter baumannii is highly resistant to carbapenems, and methicillin-resistant Staphylococcus aureus detection rates are on the rise and should be closely monitored.
