Objective To compare the effect of different intensity of neuromuscular training(NMT)on muscle strength and knee joint function of patients after anterior cruciate ligament reconstruction(ACLR).Methods From January,2023 to January,2024,60 ACLR patients in Changhai Hospital were selected,and they received the same intensity of NMT from one to eight weeks after surgery.Eight weeks after surgery,they were randomly divided into low intensity group(n=30)and high intensity group(n=30),and then they received different inten-sities of NMT from nine to 16 weeks after surgery,each training session lasted one hour,with three sessions per week,totaly 48 sessions.The Lysholm score,knee flexor and extensor muscle strength and muscle endurance-were compared at eight weeks and 16 weeks after surgery.Results After group training,the Lysholm score significantly increased in both groups(|t|>13.739,P<0.001),and was higher in the high intensity group than in the low intensity group(t=-2.574,P<0.05);in the high intensity group,the relative peak torque and endurance of the extensor and flexor muscles improved at angular velocities of 60°/s,120°/s and 180 °/s(|t|>2.320,P<0.05);in the low intensity group,the flexor peak torque improved at all the three angular velocities(t>2.177,P<0.05),the extensor peak torque improved at angular velocities of 60°/s and 180°/s(|t|>1.715,P<0.05),and the extensor endurance improved at angular velocity of 60°/s(t=-2.293,P<0.05).However,there was no significant difference in the relative peak torque and endurance of the extensor and flexor muscles at all the three angular velocities(P>0.05).Conclusion Both high and low intensity NMT could improve the muscle strength,muscle endurance and knee joint func-tion.Maybe,high intensity is superior to low intensity.Further verification is still needed.

"Tendency of disease" is an important concept in the theory of traditional Chinese medicine （TCM）. It was born out of and rooted in the thinking of "conducting by tendency" of ancient Chinese philosophy， meaning that the development and change of humans and nature have their own inevitable laws and dynamic tendencies. Based on the concept of holism and constant motion， the basic definition of "tendency"， the origin of the idea， the influence factors and related concepts were analysed， to grasp the overall connection in the dynamic changes in space and time， and to find a scientific and comprehensive objective law of development. The "tendency" was regarded as dynamic forces in the complex system， when yin and yang harmonized， called normal tendency； when fail to keep normal， called disease tendency； the season have sequential tendency， the earth has geographical tendency， people have body tendency， medications have medical tendency， and pulse has pulse tendency. Then the "eight methods of treating tendency" were summed up as observing tendency， evaluating tendency， waiting for tendency， accumulating tendency， favoring tendency， counteracting tendency， preventing tendency， and borrowing tendency， and condenses the methodo-logical thinking of "treatment according to disease tendency"， with a view to re-understanding the internal logic of TCM diagnosis and treatment， and providing metaphysical contemplation and exploration for the construction of a new paradigm of TCM syndrome differentiation and treatment.

Objective : To investigate the effects of D ⁃allose on the restoration of neurological function , Galectin⁃3 (Gal⁃3) , adenosine monophosphate⁃activated protein kinase/mammalian target of rapamycin (AMPK/mTOR) and the expression of some inflammatory factors in ischemia⁃reperfusion injury ( CIRI) mice . Methods : A total of 50 male mice were randomly divided into control group (Con group) , sham group (Sham group) , cerebral ischemia⁃reperfusion injury group (MCAO group) , cerebral ischemia⁃reperfusion injury + D ⁃alolose group (MCAO + D ⁃allose group) and cerebral ischemia⁃reperfusion injury + modified citrus pectin group (MCAO + MCP group) . The middle cerebral artery occlusion/reperfusion (MCAO/R) model (reperfusion after 2 hours of MCA ischemia) was established by thread embolism . After successful modeling , the neurological function of mice was evaluated Longa score and rotated rod walking . TTC staining was used to observe the volume of cerebral infarction foci . The expression levels of Gal⁃3 and autophagy⁃related molecules were detected by Western blot and RT⁃PCR . Immunofluorescence was applied to detect the distribution of Gal⁃3 in brain tissue , and TNF⁃α , IL⁃8 secretion was detected with ELISA KIT . Results : Compared with Con group and Sham group , the MCAO model represented significant increase in the Longa neurofunction score (P < 0. 01) , cerebral infarction volume ( P < 0. 01) , Gal⁃3 expression and manifasted enhanced autophagy (P < 0. 01) . After treatment with D ⁃allose , it could significantly improve neurological dysfunction , reduce cerebral infarction volume (P < 0. 01) , reduce the expression of Gal⁃3 ( P < 0. 01) , inhibit AMPK phosphorylation , promote mTOR phosphorylation , and inhibit autophagy (P < 0. 01) . The use of the Gal⁃3 inhibitor MCP alone could also achieve the effect of inhibiting autophagy . Conclusion D ⁃allose can effectively promote the recovery of neurological function and reduce the volume of infarct foci in CIRI mice . The mechanism may involve inhibiting excessive cell autophagy by downregulating the expression of Gal⁃3 , and reducing the release of inflammatory factors such as TNF⁃α and IL⁃8 , thereby exerting neuroprotective effects .

Objective To evaluate the diagnostic value of multi-slice spiral CT (MSCT)for traumatic spleen and liver rupture.Methods We made a retrospective analysis of 140 cases of liver and spleen injury with clinical manifestations confirmed by operation.MSCT examination results and clinical data were compared.Results Of the 140 cases,male patients outnumbered female ones,and the peak age was 10 - 30 years old.The injuries were most commonly attributed to traffic accident and falling.There were 69 (49%)cases of spleen injury,5 1 (36%) cases of liver injury,and 20 (14%)cases of both.Liver and spleen injuries showed on MSCT examination were liver and spleen laceration, hematoma within the liver and spleen as well as hematoma beneath the envelop. Conclusion MSCT has an important diagnostic value for traumatic liver and spleen rupture and thus can guide clinical treatment choice.

Cultivating Clinical thinking ability is an important tache of clinical medical education. Teachers'guidance, the charateristics that suit teaching, the organic combination of the active methods which can mobilize clinical medical interns' learning enthusiasm, such as problem-based learning, and humanity education are effective approaches to enhancing interns' clinical thinking ability.

Objective As estrogen increases visceral hypersensitivity induced by water avoidance stress in female rats,further experiment was designed to determine whether the influence of estrogen involves NR2B.Methods Healthy adult female Wistar rats were bilaterally ovariectomized,and then housed individually.Implantation of cannula into lateral cerebroventricle and electrodes into the abdominal muscle had been done.After 5 days recovery,rats with abnormal behavior and ehctromyography were excluded,finally a total of 48 rats were eligible,and were equipped for abdominal muscle electromyography and submitted to water avoidance stress(WAS).Visceromotor response(VMR)to 20,40,60 and 80 mmHg colorectal distension(CRD)was recorded in rats intracerebroventricular-infused with either 17β-estradiol,normal saline,AP5(NMDA receptor-antagonist)or Ro25-6981(NR2B antagonist).NR2B mRNA in anterior cingulate cortex or dorsal root ganglia were compared by real-time PCR between the rats treated with 17β-estradioI and that with normal saline.Results Bilaterally ovarieetomized rats treated with 17β-estradiol,exhibited more visceral hypersensitivity after WAS than that with normal saline on 40,60 and 80 mmHg CRD(P=0.039,P=0.033,P=O.001).The VMR on 40 and 60 mmHg CRD in 17β-estradiol treated group was not significantly different from that in 17β-estradiol plus Ro25-6981 treated group.Whilst,significant differences of VMR were noted between 17β-estradiol treated group and 17β-estradiol plus Ro25-6981 treated group on 80 mmHg CRD,17β-estradiol treated group and 17β-estradiol plus AP5 treated group on 60,80 nmmHg CRD,respectively.17β-estradiol increased NR2BmRNA in anterior cingulate cortex(0.57±0.41 vs 0.21±0.13,P=0.048),but not in dorsal root ganglia(0.35±0.45 vs 0.38±0.31,P=0.465). Stress-induced visceral hypersensitivity in the hormonally-restored visceral hyper-responsiveness of bilaterally ovariectomized rats was antagonized by AP5 or Ro25-6981.Conclusions Estrogen may be mediated through NR2B activation to enhance visceral sensitivity in female stressed rats,that probably related with the increased expression of NR2B mRNA in anterior cingulate cortex.

Objective:To perform trans-peritoneal laparoscopic adrenalectomy via a single incision in treatment of adrenal tumors,and to discuss its clinical outcome and safety.Methods:Single incision trans-peritoneal laparoscopic adrenalectomy was used in treatment of three patients with adrenal tumors.The incision was made 3 cm below the costal margin of anterior axillary line; three Tocars were placed in the cut.The instruments used included single port access,CUSA,Hem-o-lok,etc..Results:The three operations were all successful,and there were no conversion to open procedure or a need for extra Ttrocars.The operating time periods were 75,116,and 135 min,with a mean of (108.7?30.7)min.The perioperative blood losses were 10,20,and 30 ml,with a mean of (20?10)ml.The gastric canal and ureteral catheter were withdrew one day after operation,and the drainage tube was withdrew 3 d after operation.The mean postoperative hospital stay was 4 d.Conclusion:Single incision trans-peritoneal laparoscopic adrenalectomy has the advantage of little trauma,less blood loss,satisfactory safety,and prompt postoperative recovery,but is difficult to manage.
