Objective To study the effect of nucha electroacupuncture (NEA) on 5-hydroxytryptamine (5-HT) in cerebrospinal fluid (CSF) and blood of acute cerebral infarction (ACI) patients. Methods 72 cases with first ACI were randomly divided into NEA group (n= 38) and control group (n=34). Their 5-HT levels in CSF and blood were determined before and 4 weeks after treatment. Results Before treatment, the 5-HT in the CSF was (0.67±0.13) μmol/L in the NEA group and (0.71±0.11) μmol/L in the control group (P>0.05), while that in the blood was (0.44±0.19) μmol/L in the NEA group and (0.41±0.10) μmol/L in the control group (P>0.05). After treatment, the 5-HT in the CSF was (1.12±0.32) μmol/L in the NEA group and (0.83±0.15) μmol/L in the control group (P<0.05), while that in the blood was (0.87± 0.14) μmol/L in the NEA group and (0.63±0.07) μmol/L in the control group (P<0.05). Conclusion NEA can increase the 5-HT in both CSF and blood after ACI, which may facilitate to reduce post-stroke depression.

Objective To approach the methods and effects of internal fixation for Hoffa fracture. Methods A total of 26 patients with 26 condylar Hoffa fractures ( medial condylar fractures in 13patients and lateral condylar fractures in 13) treated from August 1993 to February 2010 were retrospectively analyzed.According to the Letenneur classification,there were 16 patients with type Ⅰ fractures,four with type Ⅱ fractures and six with type Ⅲ fractures.Among them,two patients were with open fractures and 24 with closed fractures.Surgical approaches including screw fixation in 21 patients and lateral support plate fixation in five were selected based on the fracture types and affected sides. Results All patients were followed up for 12.5-48 months (average 18 months),which showed fracture healing in all the patients within 3-4 months (average 3.5 months).Two patients had slight shift together with knee joint pain,ie,one patient had ROM of knee for 95 °,and one failed the functional exercise because of pain and had ROM of knee for 60° during follow up.No complications including infection,delayed union or bone necrosis occurred.According to Letenneur' s functional assessment system,the postoperative outcomes were excellent and good in 24 condyles,fair in one and poor in one. Conclusions Surgical treatment for Hoffa fractures is safe and effective,but the key point is to choose correct screw fixation position and orientation according to the fracture types and fracture fragment size.

Objective To investigate the clinical effects of surgical treatment of lower lumbar fracture with mini-incision via retroperitoneal anterior approach. Methods The data of 21 cases with serious lower lumbar burst fracture were analyzed retrospectively. There were 15 males and 6 females with an average age of 35.9 years (ranged, 19-65 years). The lesion was located in L3 in 10 cases, L4 in 8 and L5 in 3cases. According to Magerl classification, there was type A (burst in 12 cases, type B (distraction) in 2 and type C (retortion) in 7 cases. All the 21 cases were treated with anterior decompression, bone graft fusion and internal fixation with mini-incision via retroperitoneal anterior approach. The changes of radiograph and neurologic status were recorded respectively. Results All the cases had been followed up for an average of 41.9 months (12-86 months). The radiograph showed obvious improvement on the injured body height (from 42.62％ preoperatively to 94.33％ postoperatively, P＜0.01) and the canal encroachment index (from 2.67 preoperatively to 0.14 postoperatively, P＜0.01). Significant improvement in neurological function were achieved in all patients with the improvement of one grade except for 1 case with L3, T11 fracture and complete paraplegia. No failure of implants was found during the follow-up period. Conclusion Anterior decompression and internal fixation with mini-incision via retroperitoneal anterior approach are successful in treating serious lower lumbar burst fractures.

Methods Fifteen patients with AMVT who diagnosed by imageology were treated by interventional procedures. Eight patients were treated by transcatheter superior mesenteric artery thrombolysis with urokinase, 5 cases by percutaneous transhepatic treatment, 2 cases by transjugular intrahepatic portosystemic shunt approach. Results The technical success was achieved in all the 15 cases without complications. The majority of the thrombus was cleared by interventional procedures and flow restorated on the angiograms. All the patients with follow-up from 10 to 22 months showed no recurrence. Conclusion The minimally invasive interventional techniques are safe and effective in the treatment of mesenteric venous thrombosis without necrosis.

Objective? To explore the effects of motivational interviewing rehabilitation transitional care based on action research on rehabilitation and functional recovery among stroke patients. Methods? From January 2017 to December 2017, we selected 80 stroke patients treated in Xinyang Central Hospital as subjects by convenience sampling. All the patients were divided into control group (n=40, routine discharge nursing for 12 months) and observation group (n=40, motivational interviewing rehabilitation transitional care based on action research for 12 months) with the random number table. The National Institutes of Health Stroke Scale (NIHSS), Fugl-Meyer Assessment (FMA), Activity of Daily Living (ADL) and Hamilton Depression Scale (HAMD) were used to evaluate the recovery of nerve function, motor function, ADL and depression of patients at discharge and 6 months after discharge, and we also compared the satisfaction with nursing between two groups. Results? At discharge, there were no statistical differences in the scores of NIHSS, FMA, ADL and HAMD of patients between two groups (P＞0.05). Six months after discharge, the scores of NIHSS, ADL and HAMD of patients in observation group were lower than those in control group;the score of FMA in observation group was higher than that in control group all with statistical differences (P＜0.01),and the satisfaction rate of the observation group was higher than that of control group with statistical difference (P＜0.01). Conclusions? The motivational interviewing rehabilitation transitional care based on action research can accelerate the process of rehabilitation of stroke patients, relieve depression, improve their ADL, quality of life and satisfaction with nursing.

Non-lethal electric shock devices such as Taser have been widely used by military and police agencies worldwide. Taser can temporarily incapacitate human body mainly through discharge on skeletal muscle, while causing injuries to the tissues and organs such as the heart, skeletal muscle, blood vessel, eyeball, brain, bone and neuropsychiatric behavioral disorders through direct or indirect effects of electrical discharge, mechanical puncture, burning and infection. Though Taser has been introduced into China, there have been few studies about the damage to human body caused by Taser and no relevant systematic medical reviews have been found. However, an overall understanding of the characteristics of Taser injuries to human body is of great significance in reducing the disability and mortality rates caused by Taser as well as treating the injuries. To this end, the authors reviewed the research progress on human body injuries caused by Taser from the characteristics of Taser and the types and features of Taser injuries, aiming to provide references for the diagnosis and treatment of injuries caused by Taser.
