Methods the APS group was compared withthe normal solution(NS)group by the incidence of diabetes, the serum C-peptide levels and GAD-Ab levels,the proportion of CD4 or CD8 T subsets in splencytes, pancreatic histopathology and immunocyto-chemistry.Results It shows that the APS group has lower incidence of diabetes, higher serum C-P levels, decreaseddegree of the lymphocytic inflammation of pancreatic islets, stronger proliferation of CD8 T subsets and lowerratio of CD4/CD8 subgroup in splencytes than those of the NS group. Conclusions It proves thepreventive effects of APS on the onset of type 1 diabetes in NOD mice.

Objective To investigate the role of ileocecal valve in children patients with intussus-ceptions by colonoscopy after pneumatic air enema reduction. Methods A total of 106 intussusceptions chil dren patients, who recovered with pneumatic air edema reduction, were recruited to the study. They underwent colonoscopy within 12 hours after reduction. The control group was composed of 103 children patients with both diarrhea and hematochezia. There was no significant difference in age, sex or weight between the two groups.Colonoscopic findings were recorded in terms of slack, swelling, prolapsus, lymphoid hyperplasia and mucosal lesions in ileocecal valve. Results In patients with intussusceptions, the rates of ileocecal valve slack, swelling including prolapsus, lymphoid hyperplasia and mucosal lesions were 61.3%, 33. 9%, 100. 0% and 31.1%, respectively, which were significantly different with those of the control group (P ＞ 0. 05 ). When further divided intussusceptions patients into groups with age more than 1 yr or less, significant differences were also observed in regarding of these features. Conclusion There is a close relationship between morphological and functional changes in ileocecal valve and intussusceptions in children. Ileocolic intussusceptions in patients younger than 1yr is more likely to be due to slack of ileocecal valve, while that in patients older than 1yr is mainly due to swelling or prolapse of ileocecal valve, represented by ileocecal intussuception.

Objective To investigate the mechanism of icariin regulating the NLRP3 inflammasome in the treatment of cerebral ischemia-reperfusion injury in rats.Methods A rat model of focal cerebral ischemia-reperfusion was induced using the thread embolism method.At 24 hours post-operation,the rats were randomly allocated into a sham operation group,model group,butylphthalide group(70 mg/kg),ICA-low dose(20 mg/kg),ICA-middle dose(40 mg/kg),and ICA-high dose(80 mg/kg)groups.The corresponding drugs were administered by gavage at 10 mL/kg once a day for 13 consecutive days.One hour after the last administration,neurological function was scored.The cerebral cortex was observed by hematoxylin-eosin(HE)staining.Expression of interleukin(IL)-1β and IL-18 in the cerebral cortex was determined by immunohistochemistry.Expression of NLRP3,ASC,and Caspase-1 in the cerebral cortex was determined by Western Blot.Results In contrast to the sham operation group,there was a notable increase in neural function scores within the model group.The ischemic area around the visible cerebral cortex showed neuron necrosis at various level or glial cell proliferation,and the number of intact neurons was significantly reduced.IL-1β and IL-18 positive cells were significantly increased.Expression of NLRP3,ASC,and Caspase-1 was significantly increased(P＜0.01,P＜0.05).After treatment with icariin,the neural function score was decreased significantly.The degree of neuronal necrosis in the peri-ischemic area was significantly reduced,and the number of intact neurons was significantly increased.IL-1 β and IL-18-positive cells were decreased significantly.Expressions of NLRP3,ASC,and Caspase-1 were significantly decreased(P＜0.01,P＜0.05).Conclusions Treatment of cerebral ischemia-reperfusion injury by icariin may be related to regulation of the NLRP3 inflammasome.

OBJECTIVETo evaluate its mechanism of inducing the maternal-fetal immune tolerance by studying the effects of Shoutai pills on the expression of Th1/Th2 cytokine and pregnancy in maternal-fetal interface of mice with recurrent spontaneous abortion (RSA).

METHODThe normal pregnancy and RSA model were respectively induced with CBA/J x BALB/c and CBA/J x DBA/2. The mice with RSA were randomly divided into model group and low, middle and high dose groups of Shoutai pills. The mice were killed in 14 days after administration and embryo resorption rate was counted and their decidual and placental tissues were co-cultured to detect the expressions of IL-4, IL-10, IFN-gamma and TNF-alpha with ELISA.

RESULTThe embryo resorption rate of the model group was significantly higher than the normal pregnancy, middle and high dose groups of Shoutai pills could decreased the embryo resorption rate of the mice with RSA (P < 0.05). All the doses in 3 groups of Shoutai pills could decreased the expression of IFN-gamma and TNF-alpha (P < 0. 05) and there was no obvious difference between normal pregnancy group and all groups of Shoutai pills. Middle and high doses of Shoutai pills could increased the expression of IL-4 and IL-10 (P < 0.05) and there was no obvious differences between normal pregnancy and high dose group of Shoutai pills.

CONCLUSIONThe mechanism about Shoutai pills can change Th1 /Th2 cytokine towards Th2 bias, which induced the maternal-fetal immune tolerance.

Objective:To explore the effects of different concentrations of ropivacaine ultrasound-guided transverse abdominis plane block on postoperative pain and stress response in patients undergoing laparoscopic sleeve gastrectomy.Methods:A prospective study was conducted on 120 obese patients who underwent laparoscopic sleeve gastrectomy at the Puren Hospital Affiliated to Wuhan University of Science and Technology from July 2020 to July 2022. According to the random number table method, all patients were divided into a control group, a low concentration group, and a high concentration group, with 40 cases in each group. All three groups underwent ultrasound-guided transverse abdominis plane block after general anesthesia induction. The control group was injected with physiological saline, while the low concentration group and high concentration group were injected with 0.25% and 0.50% ropivacaine, respectively. Stress response indicators before and after surgery in three groups [adrenaline (E), cortisol (Cor), free thyroxine (FT4), and C-reactive protein (CRP)], hemodynamic indicators [mean arterial pressure (MAP) and heart rate (HR)], glucose and lipid metabolism indicators [fasting blood glucose (FBG), 2-hour postprandial blood glucose (2-hour PBG), glycated hemoglobin (HbA 1c), total cholesterol (TC), and triglycerides (TG)] and Visual Analog Scale (VAS) score were compared before and after surgery. Results:On the 1st day after surgery, the levels of E, Cor, FT4, CRP, FBG, 2-hour PBG, HbA 1c, TC, and TG in the high concentration group were lower than those in the control group and low concentration group (all P<0.05); 15 minutes after anesthesia and 2 hours after surgery, the MAP and HR of the high concentration group were higher than those of the control group and the low concentration group (all P<0.05); At 6, 12, and 24 hours after surgery, the VAS score of the high concentration group was lower than that of the control group and the low concentration group (all P<0.05); There was no statistically significant difference in the incidence of airway reactions during anesthesia induction among the three groups ( P>0.05). Conclusions:In laparoscopic sleeve gastrectomy, administering 0.50% concentration of ropivacaine ultrasound-guided plane block of the transverse abdominis muscle has a strong postoperative analgesic effect, which can improve E, Cor, FT4, and CRP levels, and is worthy of clinical application.

Objective:To observe the dynamic of neurological severity scores (NSS) and the expressions of Wnt/β-catenin signaling pathway, brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in rats with severe traumatic brain injury (sTBI), and to explore the effect of Huoxue Huayu decoction.Methods:A total of 126 Sprague-Dawley (SD) rats were randomly divided into seven groups by random number table with 18 rats in each group, namely control group (normal saline 2 kg/L), model group (normal saline 2 kg/L), brain protolysate group (BP group, 5.6 g/kg), Taohong Siwu decoction group (TH group, 10.2 g/kg), Xuefu Zhuyu decoction group (XF group, 15.6 g/kg), Tongqiao Huoxue decoction group (TQ group, 9.6 g/kg) and Buyang Huanwu decoction group (BY group, 28.7 g/kg). The sTBI rat model was reproduced by modified Feeney free fall method, and the rats in the control group were not treated with trauma. The rats in each group were intragastrical administered with corresponding drugs at 6 hours after injury, and the NSS scores were evaluated on the 1st, 3rd and 7th days after injury. After the hippocampus was harvested, the mRNA expressions of Wnt3a and β-catenin were detected by reverse transcription-polymerase chain reaction (RT-PCR), and the positive expressions of BDNF and NGF were detected by immunohistochemistry.Results:Compared with the control group, the rats in the model group showed obvious symptoms of craniocerebral injury at 1 day after injury, which was manifested as significantly increased NSS score, up-regulated mRNA expressions of Wnt3a and β-catenin, and increased positive expressions of BDNF and NGF, which indicated that the sTBI rat model was successfully prepared and presented a certain self-repair ability with the extension of time. Compared with the model group, NSS scores in the XF group, TQ group and BY group significantly decreased at 1 day after injury (6.6±1.5, 6.1±2.0, 5.7±2.4 vs. 9.4±1.5, all P < 0.05); however, the NSS scores in the BP group and TH group decreased significantly at 7 days after injury, and the NSS scores in the TQ group and BY group decreased more significantly than those in other drug groups. Compared with the model group, mRNA expressions of Wnt3a and β-catenin in the hippocampus of the BP group increased significantly at 1 day and 3 days after injury, respectively, and continued to increase with the extension of time. The mRNA expression levels of Wnt3a and β-catenin in the four groups of Huoxue Huayu decoction fluctuated to varying degrees from 1 day to 3 days after injury, but they were significantly higher than those in the model group at 7 days after injury, and the increase was more significant in the BY group [Wnt3a mRNA (2 -ΔΔCt): 154.7±4.1 vs. 17.4±1.0, β-catenin mRNA (2 -ΔΔCt): 17.05±0.45 vs. 2.74±0.13, both P < 0.05], and the second was the TQ group [Wnt3a mRNA (2 -ΔΔCt): 126.6±2.8 vs. 17.4±1.0, β-catenin mRNA (2 -ΔΔCt): 8.70±1.19 vs. 2.74±0.13, both P < 0.05]. Compared with the model group, the positive expressions of BDNF and NGF in the BP group increased significantly at 1 day after injury, but decreased after 3 days after peak. The positive expressions of BDNF and NGF in the four Huoxue Huayu decoction groups fluctuated to varying degrees from 1 day to 3 days after injury, but they were significantly higher than those in the model group at 7 days after injury, among which, the positive expressions of BDNF and NGF in the TQ group and BY group were significantly higher than those in the model group at 1 day after injury [BDNF positive cells (cells/MP): 56.4±6.2, 61.6±7.0 vs. 37.4±2.0, NGF positive cells (cells/MP): 58.4±5.0, 62.4±4.4 vs. 53.4±3.6, all P < 0.05], the increase amplitude at 7 days after injury was more significant than those in the other groups. Conclusions:Taohong Siwu decoction, Xuefu Zhuyu decoction, Tongqiao Huoxue decoction and Buyang Huanwu decoction have curative effect on the nerve regeneration and repair of rats with sTBI at acute stage, but the intensity of the effect is different. Buyang Huanwu decoction and Tongqiao Huoxue decoction have a fast and better effect.

Undergraduate education started late in rehabilitation medicine in mainland China.At present,there are some shortcomings in current undergraduate education for rehabilitation medicine in mainland China,mainly due to the shortage of teachers,the poor pertinence of professional subjects,the broad and superficial knowledge,and the lack of close connection with the necessary professional knowledge of rehabilitation technologies.The Department of Rehabilitation in Taiwan starts its undergraduate education earlier.The curriculum has been sub-professionally oriented.Its subjects are highly targeted and detailed in content.At the same time,it emphasizes forward-looking education such as "statistics".In view of this,the mainland colleges and universities should standardize the undergraduate education of rehabilitation therapies,strengthen the training of professional teachers,pay attention to the cross-mutualism of theory and practice in the teaching plan,enrich the number of professional courses,the appropriate introduction of teaching methods of scientific research,standardize the teaching management system.
