Objective To investigate the effect of reinforcing spleen and kidney method on adriamycin-induced CKD in rats and to explore its possible mechanism.Methods Totally 36 Sprague-Dawley rats were randomly divided into a Adriamycin-induced model group and a control group.The model group was further divided into five groups:the Adriamycin-induced model control group,bennazepril-treated group,and TCM treated low,moderate,and high dose groups.The level of serum creatinine,urea nitrogen,24hours urine protein and urine creatinine were measured at 14,28,42 days after establishing the model rats.And the protein expression of transforming growth factor-β1 (TGF-β1) and cyclin-dependent kinase inhibitor p21cip1 (p21)were detected by immunohistochemistry.Results The proteinuria was observed on the seventh day after injection of adriamycin in adriamycin nephropathy model group,and reached summit on the fourteenth day.Both TCM treated groups and benazepril group reduced the level of urine protein within 24 hours (P＜0.05),the reduction was most remarkable in the TCM high dose group.The expression of p21 and TGF-β1 (p21 288627.66±97021.65,TGF-β1 98405.14± 19216.89) in kidney increased in the model groups,while the TCM treated high dose group (p21 518886.35±6810.89,TGF-β1 222012.95± 50484.73) was significantly lower than the model control group (P＜ 0.05).Conclusion Reinforcing spleen and kidney method could decrease the level of urine protein within 24 hours by regulating the expression of p21 and TGF-β1,so thus to protect renal function and delay progress of kidney disease.

30 sexually mature, virgin female SD rats, weighed 200-270 g were mated and used for the study of the teratogenic effect of N, N-methylene-bis (2-amino-1,3,4-thiadiazole) (Bis-A-TDA) on fetal neural tube formation and to explore the possible morphological mechanism of neural tube defects (NTD). In the morning of day 10 of gestation, the experimental group was administered with 10mg/kg body weight Bis-A-TDA mixed in peanut oil, and the control group with the same amount of peanut oil only. The results Showed that the incidence of NTD was 52.9% and the majority of NTD were excencephaly and encephalocele in the experimental group. In the early stage of NTD formation, some neuroepithelial cells showed vacuolated degeneration and necrosis, and the mitochondria became swollen and with indistinct or even disappeared crista. The intercellular spaces widened, and some cells escaped into the lumen of neural tube. The mitotic index of neuroepitbelial cells were sharply decreased. In the closure region of the telencephalon, similar changes of the neuroepithelium were present also, and decreased migration of mesodermal cells was noted. We consider the failure of cranial neural folds to approximate and closure was caused mainly by the damage of neuroepithelial cells, inhibition of cell proliferation, alteration of intercellular junctions and the changes of topographical arrangement of the neuroepithelium. The damage and delayed migration of mesodermal cells might also be involved in this event.

OBJECTIVE To detect the condition of bacteria of the air in wards of our hospital in order to reduce the possibility of air spread. METHODS Ten tuberculosis wards were chosen at random for study.Detected the bacteria content of the air in wards used before and after respectively and analysed the results. RESULTS The average of backgroud bacteria was 164 CFU/m 3 before the wards were used.Two years later,the average of bacteria increased to 682 CFU/m 3.The ratio was 1∶3:2 on average.There were significant differences between them. CONCLUSIONS Humen are the main facters that make the air polluted in these wards.The bacteria content will decline by good environment cleaning sanitation,ventilation and strengthening steriling management.Infection will decline in the hospital.

ObjectiveTo investigate the effect of out-patient training combined with family training under doctor's instructions on children with cerebral palsy (CP).Methods80 CP children were selected as treatment group and trained one to three months by therapists at out-patient department, then continually trained at family by parents who received doctor's instructions 30 min once every two or three months. 60 CP children in hospital were selected as control group. Rehabilitative effects of two groups were compared.ResultsIn the first and third month after training completed, movement growth of treatment group was not different from that of control group (P>0.05), but in the sixth month, was significant different from that of control group (P<0.05). The effect of treatment group was better than that of control group.ConclusionOut-patient training combined with family training under doctor's instructions can decrease treatment expenses, and is convenient and effective for CP children.

Plasma concentrations of ?-endorphin (?-EP), leucine enkephalin (L-EK), neurotensin (NT), arginine vasopressin (AVP), renin activity (PRA) and angiotensin Ⅱ (AT Ⅱ ) were measured by radioimmunoassay in 60 normal persons and 120 hypertensive patients. There were lower levels of ?-EP and L-EK (P

Objective A surface feedback-stimulation gastric-pacing device was designed to extract gastric surface information,determine the status of gastric and surface stimulation.Methods The characteristic parameters of gastric electrical formed by processing signal and extracting parameter.By that,the state of stomach could be confirmed,and stimulus signal of stomach pace-making in different frequency and intensity could be decided as needed.During the processes of the stimulation,the variations of gastric electrical parameters can be analyzed in real-time and the stimulation parameters could be modified to achieve the self-feedback mode.Results Self-feedback model in different gastric motility analog environment could be realized.Conclusion The preliminary validation of experimental results proved the effectiveness of self-feedback of gastric pacing devices and its application prospects in some areas.

Objective To observe the changes and clinical significance of procalcitonin(PCT) level in children with bacterial pneumonia.Methods The levels of PCT,hs-CRP and WBC were detected in 31 pneumonia children pre and post antibiotic treatment,and the changes were observed.Results The PCT levels of the 31 patients were all increased before treatment.After cured,PCT level of 28 cases returned to normal.But in the 28 normal cases,WBC level increased in 10 cases(35.7％),and hs-CRP level elevated in 4 cases(14.3％).In the other 3 cases,the PCT levels decreased from 5.69ng/mL,1.25ng/mL and 0.83ng/mL at admission to 0.51ng/mL,0.55ng/mL and 0.52ng/mL,respectively.And in these 3 cases,there was one case with the levels of WBC and hs-CRP respectively ascended,in which WBC level descended from 13.1 × 109/L to 12.1 × 109/L and hs-CRP level reduced from 20.92mg/L to 7.38mg/L.Conclusion The sensitivity of the index PCT is the highest at the accurate time phase of bacterial pneumonia,which can guide the reasonable use of antibiotics.

OBJECTIVE To re-evaluate systematic review/meta-analysis of escitalopram in the treatment of depression， and to provide reference for clinical use of escitalopram. METHODS Retrieved from CNKI， Wanfang database， VIP， SinoMed， PubMed and the Cochrane Library， etc.， systematic review/meta-analysis of escitalopram in the treatment of depression were collected from the construction of the database to May 17， 2022. The literatures were screened according to the inclusion and exclusion criteria， the basic information of the included literatures was extracted， and the methodological quality， reporting quality and evidence quality of the included literatures were evaluated by using AMSTAR 2 scale， PRISMA statement， and GRADE system， respectively. RESULTS A total of 16 systematic reviews/meta-analyses were included. The results of efficacy comparison showed that escitalopram in the treatment of depression was superior to sertraline in improving the total effective rate， and was comparable to paroxetine， duloxetine and fluoxetine in improving cure rate. The results of safety comparison showed that the safety of escitalopram was higher than that of paroxetine and venlafaxine. The overall methodological quality evaluation of AMSTAR 2 scale was low， and all of them were rated as extremely low； main reason was the lack of many key items. PRISMA score was between 12 and 23 points. Among them， there were 5 literatures with scores ＞21 points， and the reports were relatively complete， 10 literatures with scores between 15 and 21 points， and the reports had certain defects， and 1 literature with scores ≤15 points， with serious information missing. The results of the grading of GRADE evidence showed that， of the 160 included outcome indicators， 69 were moderate evidence， 64 were low-level evidence， and 27 were very low-level evidence. CONCLUSIONS The total effective rate of escitalopram in improving depressive patients is not inferior to that of sertraline； compared with paroxetine， escitalopram is safer. However， the evidence level of the above conclusions is low.

Objective This paper investigates the effect of a multi-physical field fusion intervention based on transcranial direct current stimulation(tDCS),transcranial magnetic stimulation(TMS)and music on mental fatigue.Methods After fatigue induction,10 subjects received blank group stimulation,music group stimulation and tDCS-TMS-Music stimulation,respectively.tDCS stimulation sites were located in the bilateral frontal regions of the subjects,and TMS stimulation sites were located in the bilateral occipital regions of the hindbrain.Heart rate variability and reaction performance were measured before and after each intervention to determine the elimination effect of different intervention programs on mental fatigue.Results Compared with the control group,the tDCS-TMS-Music group showed significantly greater improvements in subjective mental workload,response performance,and heart rate variability.Conclusion The results of this study support that tDCS-TMS-Music can effectively alleviate mental fatigue induced by long-term cognitive performance tasks,and the intervention effect is better than music intervention and resting-state relief at the same time.
