Objective:To analyse the curative effect and immune indices of tripterygium glycosides on glomerulonephritis rats . Methods:Aged Wistar rats were randomly divided into 3 groups , Group A:glomerulonephritis model rats received tripterygium glyco-sides treatment;Group B:healthy Wistar rats received no treatment; Group C: glomerulonephritis model rats received no treatment . Results:12 weeks after experiment , Group A and Group C had higher levels of 24-hour urine protein than Group B and these of pre-experiment(P<0.05).Group A had a lower level of 24-hour urine protein than Group C(P<0.05).Group A and Group C had high-er levels of TG, TC than Group B, with lower levels of ALB than Group B (P<0.05).Group A had lower levels of TG, TC than Group C, but a higher level of ALB than Group C (P<0.05).Group A had a higher rate of 0-1 grades in pathology grade than group C(χ2 =6.667,P=0.010).Group C had higher levels of TNF-αand IL-6 than Group B and Group A (P<0.05).Conclusion:Tripterygium glycosides can reduce the urine protein excretion of rats that with mesangial proliferative glomerulonephritis , rectify dyslip-idosis, raise plasma-albumin, decrease the protein expression of TNF-αand IL-6 in glomerulus.

Objective To investigate the effect of sevoflurane on blood pressure in patients with different ages and the optimal concen-tration of sevoflurane. Methods 60 patients underwent selective LC operation with conventional induction and sevoflurane maintenance were divided into three groups:the youth group (34 patients), the middle age group (20 patients) and the older age group (6 patients). The SBP, DBP, MAP, CETsev, number of patients, age of patients before induction and 10 min(T1), 20 min(T2), 30 min (T3), 60 min (T4) after induction were recorded. Results Fluctuate of blood pressure were in the normal range after anesthesia maintenance, and MAP were fluctuated within the range of ± 20% before induction. The age under different CETsev were of no significant difference in each time point (P>0. 05). The age composition ratio in different CETsev were of no significant difference in each time point (P>0. 05). As the time of anesthesia extended, the number of patients under 0% ~1%CETsev decreased from 35 to 11; the number of patients under 1% ~2%CETsev increased from 10 to 20;and the number of patients under 2% ~3%CETsev maintened in 14 approximately. Conclusion The effect of sevoflurane on blood pressure of different ages is approximate. 2% ~3% CETsev is the most optimal concentration during the main-tenance of anesthesia.

OBJECTIVE:To reduce the error rate of inventory in the automated pharmacy of our hospital. METHODS:Activi-ties were designed and implemented by the management method of quality control circles(QCC)-PDCA(Plan,Do,Check and Ac-tion)cycle. The reasons for the errors of inventory in the automated pharmacy were analyzed to investigate and implement counter-measures. Visible and invisible achievements were evaluated,and then standardized processes were made. RESULTS:The errors of inventory in the automated pharmacy mainly included those of drug dispensing,drug shelving,drug return sheet,automatic medi-cine dispensing machine and system. In view of the above reasons,relevant standards were formulated and performed,including the process of warehouse-out check and shelving of drugs,drug dispensing process for the automated pharmacy,the process of sec-ondary check,etc. After the implementation of the activities,the error rate of inventory in the automated pharmacy reduced from 9.17% to 3.77%,which was visible achievement;and the above-mentioned standardized processes could ensure continuous run-ning of PDCA cycle. The practice,sense of responsibility,communication and coordination of management members in PDCA cy-cle namely invisible achievements were improved to some extent. CONCLUSIONS:The management method of QCC-PDCA cycle is feasible in reduction of the error rate of inventory in the automated pharmacy,which can provide a reference for automated phar-macy management.

This study investigated the effects of hyperoxia on dynamic changes of thioredoxin-1 (Trx1) and thioredoxin reductase-1 (TrxR1) in alveolar type II epithelial cells (AECII) of premature rats. Pregnant Sprague-Dawley rats were sacrificed on day 19 of gestation. AECII were isolated and purified from the lungs of premature rats. When cultured to 80% confluence, in vitro cells were randomly divided into air group and hyperoxia group. Cells in the hyperoxia group were continuously exposed to 95% O(2)/5% CO(2) and those in the air group to 95% air/5% CO(2). After 12, 24 and 48 h, cells in the two groups were harvested to detect their reactive oxygen species (ROS), apoptosis, TrxR1 activity and the expressions of Trx1 and TrxR1 by corresponding protocols, respectively. The results showed that AEC II exposed to hyperoxia generated excessive ROS and the apoptosis percentage in the hyperoxia group was increased significantly at each time points as compared with that in the air group (P<0.001). Moreover, TrxR1 activity was found to be markedly depressed in the hyperoxia group in comparison to that in the air group (P<0.001). RT-PCR showed the expressions of both Trx1 and TrxR1 mRNA were significantly increased in AECII exposed to hyperoxia for 12 and 24 h (P<0.01), respectively. At 48 h, the level of Trx1 mRNA as well as that of TrxR1 mRNA in the hyperoxia group was reduced and showed no significant difference from that in the air group (P>0.05). Western blotting showed the changes of Trx1 protein expressions in the hyperoxia group paralleled those of Trx1 mRNA expressions revealed by RT-PCR. It was concluded that hyperoxia can up-regulate the protective Trx1/TrxR1 expressed by AECII in a certain period, however, also cause dysfunction of the cytoplasmic thioredoxin system by decreasing TrxR1 activity, which may contribute to the progression of oxidative stress and cell apoptosis and finally result in lung injury.

Alzheimer's disease is a common central neurodegenerative disease， mainly manifested by cognitive impairment and non-cognitive neuropsychiatric symptoms that severely affect patients' daily life and behavioral functioning. The pathogenesis of Alzheimer's disease is still unclear， and the western medicine currently used to treat Alzheimer's disease is only symptomatic， with a single pathway， limited efficacy， and many side effects. In recent years， with the deepening of research on Alzheimer's disease， the study and application of traditional Chinese medicine （TCM） in the treatment of Alzheimer's disease have gradually increased. Several studies have shown that TCM and its effective components can exert anti-Alzheimer's disease effects by regulating molecular mechanisms such as pathological protein production and aggregation， oxidative stress， neuroinflammation， ferroptosis， mitochondrial dysfunction， neurogenesis and neurotransmission， and brain-gut axis. This paper summarized the research progress of TCM in the treatment of Alzheimer's disease in recent years， so as to provide a reference for further study of the specific mechanism of TCM in the prevention and treatment of Alzheimer's disease and the discovery of effective components of TCM.

Formins are widely distributed in eukaryotes such as fungi, plants and animals. They play crucial roles in regulating the polymerization of actin, coordinating the synergistic interactions between actin and microtubules, and determining cell growth and morphology. Unlike formins from fungi and animals, plant formins have been evolved into two plant-specific types. Generally, type Ⅱ formins are believed to regulate the polarized growth of cells, and type Ⅰ formins may regulate the cell expansion and division processes. Recent studies on the function of plant formins suggest it is inappropriate to classify the function of formins purely based on their structures. This review summarizes the domain organization of formins and their corresponding functions, as well as the underpinning mechanisms. Furthermore, the unsolved or unexplored issues along with future perspectives on plant formins are proposed and discussed.
