Objective To discuss the clinical characteristics and therapeutic strategy of contrecoup contusion and laceration in frontal lobe. Methods 48 cases with contrecoup contusion and laceration in frontal lobe were analysed retrospectively with their imaging feature. Results In accordance with the GOS,36 cases survived well, 8 suffered from moderate disability. One keept in persistent vegetative state and one was dead. Conclusion Contrecoup contusion and laceration in frontal lobe merged with occipital extradural hematoma and diffuse brain swelling. Early diagnosis and treatment for the delayed occipital extradural hematoma, and standard large trauma craniotomy in treatment of heavy contrecoup contusion and laceration with diffuse brain swelling in frontal lobe were the key measures to improve the rate of success rescue.

Objective To investigate the clinical characteristics and therapeutic strategy of acute subdural hematoma. Methods A restrospective study was carried out with a total of 94 consecutive ASDH patients who were confirmed through computed tomographic scan and obtained the clinical characteristics by experienced neurosurgeons.15 cases werepure acute subdural hematoma and the other 79 cases were acute compound subdural hematoma according to CT scan. Results In accordance with the GOS,36 cases had good recovery,19 cases had moderate disability,17 cases had severe disability and 22 cases dead. Conclusion The most important treatment for pure acute subdural hematom was to diagnose the source of bleeding, and acute compound subdural hematoma had poor prognosis than pure acute subdural hematoma since the traumatic severity. Early decraniuim by large bone flap to treat acute compound subdural hematoma could improve survival rate,reduce the fatality rate and decrease postoperative complications.

ObjectiveTo discuss the clinical characteristics and therapeutic strategy of acute epidural hematoma(EDH) with mixed density on CT.MethodsThe clinical data of 45 patients with acute EDH with mixed density on the first CT after trauma were analyzed retrospectively.Acute EDH form trauma with mixed density on CT images were compared with those which had homogenesis density on CT images at the same time.ResultsThe opportunity of increasing size of hematoma and the mortality was significantly higher in mixed density hematoma( 82.1％,16.2％ )than that of homogenesis density( 17.7％,2.3％ ) ( all P ＜ 0.01 ).ConclusionEDH with mixed density was a hyperacute EDH.The operation for acute EDH from trauma with mixed density on CT image should be prompt.

Objective:To investigate the relationship between criminal’s ability to recognize facial expressions and prosocial behavior tendency, and the possible mediating role of empathy and the moderating role of social support between them.Methods:Totally 200 male criminals were surveyed with facial expressions recognition ability test, prosocial tendencies measure, interpersonal reactivity index and perceived social support scale in August 2022.SPSS 20.0 and the PROCESS macroprogram written by Hayes were used for correlation analysis, mediating and moderating effect testing.Results:Prosocial behavior tendency(79.145±12.134) was significantly negatively related with times of imprisonment(1.555±1.045) ( r=-0.227, P<0.01). Ability to recognize facial expressions had a direct effect on criminal’s prosocial behavior tendency (total effect=0.338, P<0.01), and empathy played a mediating role between them (indirect effect=0.094, P<0.01). Social support moderated the relationship between ability of recognize facial expressions and criminal’s prosocial behavior tendency ( β=0.176, P<0.01) and empathy ( β=-0.291, P<0.01), and the relationship between empathy and criminal’s prosocial behavior tendency ( β=-0.270, P<0.01). Conclusion:Facial expression recognition ability has a significant positive effect on criminal’s prosocial behavior tendency, empathy and social support play mediating role and moderating role between them.

OBJECTIVETo evaluate the clinical application of carbon nanoparticles labeled lymph node staining in curative laparoscopic resection for colorectal carcinoma.

METHODSSixty-five patients undergoing curative laparoscopic resection for colorectal carcinoma in the Sun Yat-sen Memorial Hospital between September 2011 and June 2013 were prospectively enrolled and randomly divided into label group (with carbon nanoparticles, n=34) and control group (without carbon nanoparticles, n=31). Association between labeled lymph nodes and metastasis was analyzed. The total number of retrieved lymph nodes and lymph nodes metastatic ratio were compared between the two groups.

RESULTSMean number of retrieved lymph node of the label group was higher as compared to the control group (22.3±4.2 vs. 15.4±3.5, P<0.05). The total number of retrieved lymph node was 725 in the label group and 478 in the control group. Among them, lymph node < 5 mm accounted for 4.6% (33/725) in the label group, which was higher than 2.0% (10/478) (P=0.025) in the control group. The number of black stain label lymph node was 412, with black stain ratio 56.8% (412/725) in the label group. Metastatic ratio of black stain nodes was significantly higher than that of non-stain nodes [28.6% (118/412) vs. 19.5% (61/313), P=0.005].

CONCLUSIONSThe technique of carbon nanoparticles labeled lymph node staining in curative laparoscopic resection for colorectal carcinoma is easy and effective, which can increase the retrieved number of lymph nodes, especially for nodes < 5 mm. The black stain lymph nodes indicate higher risk of metastasis.

Objective To explore the analgesic initiation mechanism of"three-manipulations and three-acupoints"of tuina on minor chronic constriction injury(minor CCI)model rats.Methods According to the random number table method,35 SD rats were randomly divided into five groups:normal group,sham group,model group,tuina group,and tuina+MK-801 group.The model group,tuina group,and tuina+MK-801 group were subjected to ligation of the right sciatic nerve trunk to establish a minor CCI rat model.The sham group was only exposed to the right sciatic nerve without ligation,and the normal group was not subjected to any operation.The normal group was not subjected to any intervention measures.On the seventh day after modeling,the model group and the sham group underwent 9 minutes of grasping restraint,while the tuina group underwent one intervention of three-manipulations(point method,dialing method,and kneading method)and three-acupoints(right"Yinmen"(BL37),"Chengshan"(BL57),and"Yanglingquan"(GB34)acupoints)with each manipulation and acupoint intervention for 1 minute for a total of 9 minutes.The tuina+MK-801 group received intrathecal injection of MK-801 from the fifth to seventh days after modeling,with a dose of 6 μg(10 μL)per day,tuina intervention was performed 30 minutes after the last intrathecal injection,and the specific operation of tuina was the same as that of the tuina group.Before modeling,after modeling,and after intervention,each group of rats was subjected to cold sensitivity threshold(CST)and mechanical withdrawal threshold(MWT)testing.After intervention,immunohistochemistry was used to detect the positive expression of cyclic guanosine monophosphate(cGMP)in the spinal dorsal horn(SDH)at L4-6 segments;protein expressions of N-methyl-D-aspartate receptor 1(NMDAR1),neurogenic nitric oxide synthase(nNOS),soluble guanylyl cyclase β(sGCβ),and protein kinase G1(PKG1)in SDH at L4-6 segments were detected by Western blotting;mRNA expressions of NMDAR1,nNOS,sGCβ,cGMP,and PKG1 in SDH at L4-6 segments were detected by real-time PCR.Results Compared with the normal and sham groups,after modeling,CST increased and MWT decreased in the model group,tuina group and tuina+MK-801 group(P＜0.05);after intervention,the positive protein expression of cGMP was increased,the protein expressions of NMDAR1,nNOS,sGCβ,and PKG1 were increased,and mRNA expressions of NMDAR1,nNOS,sGCβ,cGMP,and PKG1 were increased in SDH at L4-6 segments in the model group(P＜0.05).Compared with the model group,after intervention,CST decreased and MWT increased in the tuina group and tuina+MK-801 group(P＜0.05);the positive protein expression of cGMP was decreased,the protein expressions of NMDAR1,nNOS,sGCβ,and PKG1 were decreased,and mRNA expressions of NMDAR1,nNOS,sGCβ,cGMP,and PKG1 were decreased in SDH at L4-6 segments in the tuina group and tuina+MK-801 group(P＜0.05).Conclusion One-time tuina intervention can effectively improve the symptoms of thermal and mechanical hyperalgesia induced by peripheral nerve injury,which may initiate analgesia through the NMDAR1/cGMP/protein kinase G signaling pathway,thereby exerting immediate analgesic effect.

Objective To explore the analgesic initiation mechanism of three-manipulation and three-acupoint tuina in model rats with minor chronic constriction injury(CCI).Methods Fifty-six SD rats were divided randomly into eight groups:normal group,sham group,model 1 group,model 2 group,tuina 1 group,tuina 2 group,tuina 1+transient receptor potential vanilloid-1(TRPV1)antagonist group,and tuina 2+transient receptor potential ankyrin 1(TRPA1)antagonist group.The model,tuina,and tuina+antagonist groups were established with minor CCI models.The tuina and tuina+antagonist groups received the three-method three-point intervention(point method,dial method,kneading method,Yinmen point,Chengshan point,Yanglingquan point)7 days after modeling.The model and sham groups were subjected to grasping restraint,and the normal group received no intervention.After the respective interventions,each group was tested for changes in mechanical withdrawal threshold(MWT)and thermal withdrawal latency(TWL)to detect different types of pain.The nitric oxide(NO)content of the dorsal root ganglion(DRG)was determined by the nitrate reductase method,and changes in protein and gene expression levels of components of the TRPV1/TRPA1-NO-cGMP-protein kinase G(PKG)signaling pathway in the DRG of each group were determined by enzyme-linked immunosorbent assay,Western blot,and qPCR.Results Compared with the model group,MWT and TWL were prolonged in the tuina 1 and tuina 2 groups.Expression levels of TRPV1,TRPA1,NO,soluble guanylate cyclase-β,cGMP,and PKG1 in the DRG were significantly decreased in the tuina 1,tuina 2,tuina 1+TRPV1 antagonist,and tuina 2+TRPA1 antagonist groups.Conclusions Tuina can effectively improve the symptoms of thermal and mechanical hyperalgesia caused by peripheral nerve injury after one-time intervention.Tuina can exert immediate and continuous analgesic effects via the TRPV1/TRPA1-NO-cGMP-PKG signaling pathway.

Objective By observing the effects of"three methods and three points"tuina technique on the expression of interleukin-17F(IL-17F),interleukin-17 receptor C(IL-17RC),activator 1 of nuclear transcription factor-κB(Act1),tumour necrosis factor receptor-associated factor 6(TRAF6)and M1 microglial cell expression in the spinal dorsal horn of rats with mild chronic compressive injury(minor CCI)model,we explored the immediate analgesic mechanism of tuina on peripheral neuropathic pain(pNP).Methods Thirty-six SD rats were divided into the sham group,the model group and the tuina group according to the random number method,twelve rats in each group,and the minor CCI model was replicated by ligating the right sciatic nerve.The rats in the tuina group were subjected to pointing,plucking and kneading at the BL37,BL57 and GB34 points on the affected side using a tuina simulator,while the sham group and the model group were only grasped and restrained,and were intervened for one time.The mechanical pain test and cold plate test were used to evaluate the response of rats to mechanical stimulation and cold stimulation after immediate intervention.The protein expression of IL-17F and TRAF6 in the spinal dorsal horn of rats in each group was detected by Western blotting.The mRNA expression of IL-17F,IL-17RC,Act1 and TRAF6 in the spinal dorsal horn of rats in each group was detected by real-time PCR.The average fluorescence intensity of M1 microglia in the spinal dorsal horn of rats in each group was detected by immunofluorescence.Results Behavioral results showed that before intervention,compared with the sham group,paw mechanical withdraw threshold(PMWT)decreased and cold sensitivity threshold(CST)increased in the model group and the tuina group;after tuina intervention,PMWT in the tuina group was increased,and CST was decreased compared with the model group;after intervention,PMWT in the tuina group was increased,while CST was decreased(P＜0.05).RT-PCR results showed that compared with the sham group,mRNA expression levels of IL-17F,IL-17RC,TRAF6 and Act1 in the spinal dorsal horn of the model group were increased;compared with model group,the mRNA expression levels of above indexes in the tuina group were decreased(P＜0.05).Western boltting results showed that compared with the sham group,the expression levels of IL-17F and TRAF6 protein in the spinal dorsal horn of the model group were increased;compared with the model group,the expression levels of IL-17F and TRAF6 protein in the tuina group decreased(P＜O.05).Immunofluorescence results showed that the mean fluorescence intensity of CD40 in the spinal dorsal horn of model group was enhanced compared with the sham group;compared with the model group,the mean fluorescence intensity of CD40 in the tuina group was decreased(P＜0.05).Conclusion The"three methods and three points"tuina technique can produce immediate analgesia by inhibiting the expression of IL-17F,IL-17RC,Act1,TRAF6 and the activation of M1 microglia in the dorsal horn of the spinal cord after one intervention.
