Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To observe the effect of auricular pressure beans(APN)combined with Compound Tung-Leaf Burn Oil(CTBO)on perioperative anxiety and pain in patients undergoing circumcision.Methods:This study included 100 patients undergo-ing circumcision with the disposable circumcision anastomosis stapler in our hospital from August 2023 to November 2023,of whom 50 received routine circumcision nursing care(the control group)and other 50 APN combined with compound CTBO in addition(the ob-servation group).We compared between the two groups the anxiety scores before any intervention,30 minutes before and 24 hours and 10 days after operation,the pain scores 24 hours postoperatively and at the first change of wound dressing,the frequency of 3-day post-operative sleep awakenings,the incidence of complications,and the satisfaction of the patients.Results:Totally,94 patients com-pleted the study,46 in the observation and 48 in the control group.The anxiety scores exhibited no statistically significant difference between the two groups of patients before any intervention(P>0.05),but were markedly lower in the observation than in the control group at 30 minutes before and 24 hours and 10 days after surgery(P<0.05),and so were the pain scores24 hours after surgery and at the first change of wound dressing(P<0.05),and the frequency of 3-day postoperative sleep awakenings(P<0.05).The satis-faction rate of the patients was remarkably higher(P<0.05)while the incidence of complications significantly lower in the observation group than in the control(P<0.05).Conclusion:Auricular pressure beans combined with Compound Tung-Leaf Burn Oil can ef-fectively alleviate perioperative anxiety,reduce postoperative pain and improve satisfaction of the patients undergoing circumcision.

OBJECTIVE: This study was conducted to explore the mechanism of intestinal inflammation and barrier repair in Crohn's disease (CD) regulated by moxibustion through bile acid (BA) enterohepatic circulation and intestinal farnesoid X receptor (FXR). METHODS: Sprague-Dawley rats were randomly divided into control group, CD model group, mild moxibustion group and herb-partitioned moxibustion group. CD model rats induced by 2,4,6-trinitrobenzene sulfonic acid were treated with mild moxibustion or herb-partitioned moxibustion at Tianshu (ST25) and Qihai (CV6). The changes in CD symptoms were rated according to the disease activity index score, the serum and colon tissues of rats were collected, and the pathological changes in colon tissues were observed via histopathology. Western blot, immunohistochemistry (IHC) and immunofluorescence were used to evaluate the improvement of moxibustion on intestinal inflammation and mucosal barrier in CD by the BA-FXR pathway. RESULTS: Mild moxibustion and herb-partitioned moxibustion improved the symptoms of CD, inhibited inflammation and repaired mucosal damage to the colon in CD rats. Meanwhile, moxibustion could improve the abnormal expression of BA in the colon, liver and serum, downregulate the expression of interferon-γ and upregulate the expression of FXR mRNA, and inhibit Toll-like receptor 4 (TLR4) and myeloid differentiation factor 88 (MyD88) mRNA. The IHC results showed that moxibustion could upregulate the expression of FXR and mucin2 and inhibit TLR4 expression. Western blot showed that moxibustion inhibited the protein expression of TLR4 and MyD88 and upregulated the expression of FXR. Immunofluorescence image analysis showed that moxibustion increased the colocalization sites and intensity of FXR with TLR4 or nuclear factor-κB p65. In particular, herb-partitioned moxibustion has more advantages in improving BA and upregulating FXR and TLR4 in the colon. CONCLUSION Mild moxibustion and herb-partitioned moxibustion can improve CD by regulating the enterohepatic circulation stability of BA, activating colonic FXR, regulating the TLR4/MyD88 pathway, inhibiting intestinal inflammation and repairing the intestinal mucosal barrier. Herb-partitioned moxibustion seems to have more advantages in regulating BA enterohepatic circulation and FXR activation.

Background and purpose:It has been demonstrated that radical prostatectomy for patients with oligometastatic prostate cancer may contribute to improving local control of prostate cancer and overall survival by several retrospective studies. Perioperative complications play an important role in determining whether radical prostatectomy is appropriate for patients with oligometastatic prostate cancer. This study aimed to discuss the recurrence rate and the sever-ity of perioperative complications, and the primary curative effect of radical prostatectomy on oligometastatic prostate can-cer patients.Methods:A total number of 247 patients who received radical prostatectomy were recruited in the study from Jul. 2015 to Jan. 2016, including 25 patients with oligometastatic prostate cancer and 222 patients with localized prostate cancer. Patients with perioperative complications in both groups were graded with the Clavien-Dindo grading system. The proportion of PSA decline and the rates and severity of perioperative complications were analyzed in both groups.Results:The cases of prostate specific antigen (PSA) decline in the oligometastatic group were 21 (84.0%), lower than the localized group with 212 cases (95.5%). There were 6 cases (24.0%) with postoperative complications in the oligometastatic group, including serious complications (Ⅲ or above) 1 case (4.0%), and 49 cases (22.1%) with postoperative complications in the localized group, including serious complications (Ⅲ or above) 7 cases (3.2%). The differences between the groups reached no statistical significance (P>0.05).Conclusion:Radical prostatectomy for patients with oligometastatic prostate cancer could be safe, effective, and appropriate, the risk of perioperative complications should not be one of the limiting factors.

AIM:To investigate the effect of bone marrow mesenchymal stem cell(BMSC) transplantation on learning and memory abilities and pathological changes of Alzheimer disease (AD) mice and the molecular mechanisms. METHODS:C57/BL6 wild-type (WT) and transgenic(Tg) mice were randomly divided into 4 groups:WT/PBS group, WT/BMSCs group,Tg/PBS group and Tg/BMSCs group. The mice were administered with PBS or BMSCs via intracere-broventricular injection. Spatial learning and memory abilities of the mice were evaluated by Morris water maze test on the 3rd day after surgery. Real-time PCR was applied to detect the mRNA expression of CX3C chemokine ligand 1 (CX3CL1),CX3C chemokine receptor 1 (CX3CR1), IL-1β, TNF-α, Nurr1, YM1, insulin-degrading enzyme (IDE) and matrix metalloproteinase 9(MMP9). The protein levels of CX3CL1 and Aβ42 were measured by ELISA. Western blot was used to detect the protein expression of postsynaptic density protein 95 (PSD95) and synaptophysin (SYP). RE-SULTS:The transplanted BMSCs were observed near the hippocampus of APP/PS1 mice on the 10th postoperative day. The escape latency of the mice in Tg/PBS group was significantly longer than that in the WT/PBS mice(P<0.05). Com-pared with Tg/PBS group,the escape latency of Tg/BMSCs group was significantly shorter (P<0.05), and the mRNA and protein levels of CX3CL1 in Tg/BMSCs group were significantly higher than those in Tg/PBS group (P<0.01). The results of immunohistofluorescence staining showed that BMSC transplantation promoted the activation of microglia in the brain of WT and Tg mice. The mRNA expression of YM1 was up-regulated in WT/BMSCs group and Tg/BMSCs group (P<0.05). Compared with WT/PBS mice, the mRNA expression of TNF-α in the cortex and hippocampus of Tg/PBS group was significantly increased (P<0.05),and the mRNA expression of Nurr1 in the cortex was significantly decreased (P<0.01). Meanwhile,the mRNA expression of TNF-α in the cortex of Tg/BMSCs mice was decreased(P<0.01) and the mRNA expression of CX3CR1 and Nurr1 was up-regulated compared with Tg/PBS group (P<0.05). The results of Western blot showed that the protein levels of PSD95,p85,p110 and p-Akt in Tg/BMSCs group were significantly higher than those in Tg/PBS group (P<0.05). Finally, BMSC transplantation reduced the protein level of Aβ42 in APP/PS1 mice(P<0.05), and increased the mRNA expression of IDE and MMP9 in the hippocampus (P <0.05). CONCLU-SION:BMSC transplantation modulates neuroinflammatory responses and promotes neuroprotective factor and synaptic pro-tein expression,thus improving the learning and memory abilities in the APP/PS1 mice,which may be achieved by up-reg-ulating the expression of CX3CL1.

Objective To investigate the effect of asymmetric lumbar discectomy on facet joint force and stability of lumbar spine. Methods Seven human cadaver specimens (L2-3 segment) were selected to make intact, 1/4 discectomy and 1/2 discectomy status and applied with pure moment of 7.5 N•m. The range of motion (ROM) and facet joint force of L2-3 segment during flexion/extension, lateral bending and axial rotation were recorded, respectively. Results During extension, a significant increase in facet joint force was found under 1/4 discectomy status at the remained side. During lateral bending, the facet joint force at both sides under 1/2 discectomy status increased significantly than that under intact status. During axial rotation, facet joint force increased significantly only at the side without discectomy under 1/2 discectomy status. Except flexion, ROM under 1/4 discectomy and 1/2 discectomy status were larger than that under intact status in all the other motion directions (P<0.05). There was no significant difference in ROM between both sides during lateral bending and axial rotation direction. Conclusions The asymmetric lumbar discectomy can increase the ROM in all motion directions except flexion, and can enlarge the facet joint force asymmetrically, which indicate that instability of lumbar spine and facet joint force increasing resulted from asymmetric degeneration of the disc might lead to backache.

OBJECTIVETo observe the anti-renal fibrosis effect of Paidu Baoshen Pill (PBP) on 5/6 nephrectomized rats and to explore its mechanism.

METHODSTotally 50 SD male healthy rats were randomly divided into the normal control group (n = 10), the sham-operation group (n = 10), and the nephrectomy model group (n = 30) according to the proportion of 1:1:3. Rats in the sham-operation group had their renal capsule isolated without nephrectomy. Rats in the nephrectomy model group had their kidneys 5/6 nephrectomized. Then 24 h urine was collected and 24 h urinary protein (24 h UP) detected. Serum blood urea nitrogen (BUN) and serum creatitine (SCr) were also tested. According to the SCr level 30 rats of the model group were further randomly divided into the model group, the PBP group, and the Niaoduqing Granule (NG) group, 10 in each group. Rats in the PBP group and the NG group were respectively administered with PBP (at the daily dose of 1.0 g/kg) and NG (at the daily dose of 3.33 g/kg) by gastrogavage (they were dissolved in distilled water). At the same time, 2 mL distilled water was administered by gastrogavage to rats in the normal control group, the sham-operation group, and the nephrectomy model group, once daily for 4 successive weeks. Mental conditions, activities, hair color, shape of stool, and the body weight were observed during administration. After 4 weeks, urine was collected to detect 24 h UP. Blood was sampled to detect SCr, BUN, transforming growth factor β1 (TGF-β1), type III procollagen (PC III), collagen type IV (Col IV), laminin (LN), and fibronectin (FN). After rats were killed, their left remnant renal tissues were collected for pathological examinations. The protein expression quantity of TGF-β1 and FN was detected by immunohistochemical method. mRNA expression levels of TGF-β1 and FN were detected using real time fluorescent quantitative PCR.

RESULTSThere was no statistical difference in the above indices between the normal control group and the sham-operation group (P > 0.05). Compared with the sham-operation group, rats' general condition was poorer in the model group, their body weight grew slower, and 24 h UP increased; serum levels of BUN, SCr, TGF-β1, PC III, Col IV, LN, and FN increased; the residual renal pathological lesion was serious; expression levels of TGF-β1, TGF-β1, mRNA, FN, and FN mRNA increased in the renal tissue (all P < 0.01). Compared with the model group, rats' general condition was better, their body weight grew faster, 24 h UP reduced (P < 0.05), blood levels of BUN and SCr decreased significantly (P < 0.01), serum levels of TGF-β1, PC III, CoL IV, LN, and FN decreased (P < 0.05, P < 0.01); the residual renal pathological lesion was attenuated in the PBP group and the NG group; expression levels of TGF-β1, TGF-β1, mRNA, FN, and FN mRNA decreased (P < 0.01). Compared with the NG group, blood levels of SCr and FN, and expression levels of FN and FN mRNA decreased more in the PBP group (P < 0.05).

CONCLUSIONSPBP had the effect of anti-renal fibro- sis in 5/6 nephrectomized rats. Down-regulating expression levels of TGF-β1, and FN from gene transcription and protein translation levels might be one of its mechanisms.
