ObjectiveTo investigate the effect of patient-controlled epidural analgesia(PCEA) with opioids on serous myelin basic protein(MBP) and somatosensory evoked potential(SEP) of lower limbs in puerperants.MethodsA total of 120 puerperants,after receiving cesarean section,were divided into four groups by random number table method as group B,BR,MR and R randomly,and each group included 30 cases.After surgery,each case received PCEA:group B received 0.008％ butrophanol;group BR received 0.008％ butrophanol + 0.2％ ropivacaine;group MR received 0.004％ morphine +0.2％ ropivacaine and group R received 0.2％ ropivacaine only.VAS score,OAA/S score,adverse effect occurrence,concentration changes of serous MBP,SEP of both lower limbs and neurological function were observed at 2h(T1 ),4h(T2),8 h(T3),12h(T4),24 h(T5) and 48h (T6) after surgery.ResultsVASscoresofgroupBR(1.64±0.38,1.86±0.62,1.93±0.67) and MR( 1.74 ±0.39,1.91±0.58,1.98 ±0.63) at T3,T4,T5 were lower than those of group B(4.6 ±0.5,4.6 ±0.3,4.7 ±0.3)and R(2.64 ±0.41,2.83 ±0.91,3.37 ±0.87) (P＜0.05).There was no significance in four groups in OAA/S score at each point (P ＞ 0.05 ).Incidence of nausea ( 6 cases),vomiting ( 2 cases) and abdominal distention ( 5cases) of group M was higher than that of other three groups(P＜0.05).There was no significant difference in concentrations of serous MBP,SEP and neurological function in all four groups between preoperative time and 48h after operation(P＞0.05).ConclusionLower-dose and lower- concentration opioids used for PCEA have no influence on serum MBP and SEP.

Objective To observe the effects of Zuogui Jiangtang Jieyu Formula (ZJJF) on the ability of learning and memory and the expressions of JNK, Bcl-2 and Bax in hippocampus in diabetic rats with depression; To explore the protective mechanism of hippocampal damage in diabetic rats with depression. Methods High-fat gavage combined with intravenous injection of STZ was used to establish the model of diabetic rats. 28 days of chronic stress was given continuously and diabetic rats complicated with depression were built successfully. Then rats were randomly divided into 6 groups, including normal, model, positive medicine, high-, medium-, and low-dose of ZJJF groups. After the last administration, Morris water maze was used to detect escape latency time;Western blot was used to disclose the protein expressions of JNK, Bcl-2 and Bax in rat hippocampaus;RT-PCR was used to test the gene expressions of JNK and Bcl-2 and Bax. Results Compared with the normal group, escape latency time in model rats was significant longer (P<0.01), the protein and gene expression of JNK and Bax in rat hippocampaus significantly increased, Bcl-2 was markedly decreased (P<0.05, P<0.01);Compared with the model group, escape latency time in positive medicine group and high-dose of ZJJF group was significant shorter (P<0.01), the protein and gene expressions of JNK and Bax significantly decreased, and Bcl-2 markedly increased (P<0.05, P<0.01). Conclusion ZJJF can significantly improve the ability of learning and memory in diabetic rats with depression, which might be associated with preventing neuronal apoptosis in hippocampus.

Objective To analyze the characteristics of blood transfusion consultation cases and establish the consulta-tion route,so as to provide reference for blood transfusion doctors to participate in blood transfusion consultation practice.Methods The cases involved in clinical transfusion consultation in the blood transfusion department of our hospital from 2020 to 2023 were collected from the hospital information system(HIS),and then classified by department and consultation type to summarize the main points of transfusion consultation,formulate transfusion consultation routes,and conduct typical cases analysis.Results There were 315 clinical transfusion consultations from 2020 to 2023,with an increasing trend year by year(26 in 2020,67 in 2021,81 in 2022,141 in 2023).The consultations involved 24 departments,including cardio-vascular medicine 14.0%(44/315),orthopedics 12.7%(40/315),intensive care medicine 8.9%(28/315),general medi-cine 8.3%(28/315),cardiopulmonary disease 6.0%(19/315),etc.There were 8 categories of consultations,including 35.6%(112/315)autologous ozonized blood transfusion,23.8%(75/315)plasma exchange,14.9%(47/315)perioperative mass blood preparation(transfusion),11.4%(36/315)platelet-rich plasma therapy and 6.3%(20/315)autologous blood collection,etc.The clinical blood transfusion consultation route was formulated according to the consultation points.Six pa-tients with various diseases were treated by blood transfusion department.With effective treatment measures taken,all of them improved and were discharged.Conclusion The summary of key points of clinical blood transfusion consultation and formulation of the blood transfusion consultation route by department of blood transfusion are conducive to the implementation of blood transfusion consultation and guarantee the safety of patients.
