Objective: To investigate the effects of morphine,tramadol and lornoxicam on the secretion of inflammatory mediators by rats'peripheral blood mononuclear cells(PBMC) at their analgesic concentrations. Methods: Mononuclear cells were isolated from peripheral blood of male SD rats by the Ficoll-Hypaque method,and treated with Morphine(50 ng/ml),Tramadol(500 ng/ml) or Lornoxicam(300(ng/ml)) respectively with or without stimulation by Lipopolysaccharide(LPS) 2 ?g/ml.After incubation for 24 h,concentrations of TNF-?,IL-6 and IL-10 were determined in the cell culture supernatants by ELISA. Results: Levels of TNF-?,IL-6 and IL-10 were reduced significantly in morphine groups with or without LPS;Tramadol reduced levels of these inflammatory mediators significantly in the groups stimulated with LPS,while it had no effects on the cells cultured in normal conditions;Lornoxicam reduced IL-6 and increased IL-10 levels in either groups. Conclusion: Morphine nonselectively suppressed mediator secretions either under inflammatory or physiological conditions;Tramadol reduced inflammatory mediator secretion in LPS stimulating group,thus could benefit patients with potential sepsis;Lornoxicam significantly reduced proinflammatory cytokine IL-6 secretion and increased anti-inflammatory cytokine IL-10 secretion,and may be a choice for postoperative hyperinflammation.

Objective To explore the effect of mon-suturing peritoneum in perforating purulent infection of incisional wound of appendicitis. Methods907 patients suffered purulent perforating and gangrenous appendicitis were divided randomly into two groups:the non-suturing group of 355 patients and the control group of 552 patients.Of the non-suturing group,peritoneum was not sutured when his/her abdominal cavity was closed.It was just on the contrary to the control group.Then examined whether eoncotic rythrogenic or tender incision occurred,or whether purulent secretion flowed outside from the operative incision.These items below were also been recorded carefully:the average number of days when the temperature was abnormal,the grades of healing of incision and the average hospital stay. ResultsIn the non-suturing group,21(5.9%)patients suffered postoperative infection,the number of days of abnormal temperature was(3.8 ± 1)d on average,and the average hospital stay was(7.5 ± 1)d;in the control group,119(21.6%)patients suffered postoperative infection,the number of days of abnormal temperature was(4.3 ± 1)d on average,and the average hospital stay was(12.9 ± 1)d.First rate healing of incision in the non-suturing group was far higher than that in the control group(P＜0.05). ConclusionNon-suturing peritoneum could help internal drainage peritoneum,which was an efficient way to guard against the postoperative infection.And non-suturing was also of great significance to reduce the average number of days of abnormal temperature and hospital stay.Meanwhile,the probability of ankylenteron and incisional hernia was not increased.

Methods A cluster random sampling method was used to select left-behind students in Grade 3 to 6 in 5 primary schools in the southern rural area of Ningxia Hui Autonomous Region. Their general information were collected, their social anxiety and loneliness were evaluated by the Child Social Anxiety Scale ( SASC ) and Children's Loneliness Scale ( CLS ). The multivariate linear regression model was used to analyze the influencing factors for the social anxiety of left-behind children.

Objective The purpose of this study is to evaluate the relevance of the recovery of proprioception function and the reservation of residual torn ligamentous fiber in the anterior cruciate ligament (ACL)reconstruction.Methods A retrospective study was carried out in 65 cases of ACL injury,who were treated with double-bundle ACL reconstruction and tibial remnant preservation and tensioning.All the patients were divided into four groups according to the degree of tibial residual fiber observed in the operation,no residual fiber was found(Group A),the length of the residual fiber was less than one third of the normal ACL(Group B),the length of the residual fiber was more than one third less than two thirds of the normal (Group C),the length of the residual fiber was more than two thirds of the normal(Group D).After one year follow-up,the passive angle reproduction test was performed with magnetic angle instrument in 3 flexion ranges(flexion of 90°-60°,60°-30°,and 30°-0°).All the results were contrasted among the four groups by statistical methods.Results In the passive angle reproduction test of the 3 flexion ranges,Group A and B showed a significant difference between the test side and control side(P＜0.05),and Group C showed a significant difference between the test side and control side at the flexion of 30°-0°(P＜0.05),but Group D showed no significant difference at the 3 flexion ranges(P＞0.05).Conclusion During double-bundle ACL reconstruction,with the reservation of tibial residual tom ligamentous and tensioning may have a good effect on the recovery of proprioception function of the knees,which ensure a better functional outcome in the reconstructed knee.

With the development of minimally invasive management,laparoscopic operation has become more and more prevalent.As a surgical procedure,a serial of events,such as psychological damage,fasting,bleeding,hypothermia,pain,introduce of cathartic,gastric tube,urinary catheter and aggressive resuscitation of crystal fluid,can produce stress and delay the rehabilitation. Evidence-based medicine has demonstrated that during the laparoscopic surgery,alleviating these events is associated with milder stress reaction and fast recovery.The focus of minimally invasive surgery should be shifted from the local injury to the stress of the whole body,from the wound size to the psychological,physiological and pathological changes of the whole body,from the technique of operation to the comprehensive management during perioperative period.In summary,the minimally invasive surgery focuses more and more on minimizing the stress influence on the whole body rather than merely on the minimal incision.It is reasonable to conclude that this kind of research will bring significant innovation in minimally invasive surgery in the future.

Perioperative stroke refers to acute ischemic or hemorrhagic stroke that occurs before operation,during operation and within 30 days after operation.Although the levels of anesthesia and surgical treatment have improved in recent years,there is no significant decrease in the incidence of perioperative stroke.The traditional vascular risk factors,such as advanced age,hypertension,and diabetes,are also the risk factors for stroke onset.In addition,perioperative stroke is closely associated with the operation site,operation mode,anesthesia,and other perioperative events.The treatment and prevention of perioperative stroke is attracting more and more attention,including surgery,anesthesia,neurology and other clinicians.This article reviews the risk assessment,prevention,and treatment of perioperative stroke.

ObjectiveTo explore the application value and techniques of vaginal hysterectomy of non-prolapsed uterus lesion in primary hospital. Methods140 cases who suffered from uterine fibroid without adhesion,glandular fibroids,functional bleeding without uterine prolapse and malignant disease were selected and divided into observation group(80 cases with vaginal hysterectomy)and control group(60 cases with routine abdominal hysterectomy).Then the clinical treatment effect was analyzed. ResultsCompared with control group,peri-operative bleeding (150 ±23)ml vs(243 ±41)ml,operation time(65 ± 14.0)min vs(90 ± 27.0)min,body temperature recovery time (3 ±0.5)d vs(4 ±0.8)d,anus exhaust time(14 ± 1.8)h vs(26 ±2.7)h,the length of time(5 ±0.8)d vs(11 ±2.9)d in observation group were all reduced,differences were significant(all P＜0.01)and no case was transferred to opening appendectomy. ConclusionFor these disease including uterine fibroids with no adhesion,glandular fibroid uterine bleeding,the vaginal hysterectomy was safe and feasible,and had the advantage of smaller trauma,less bleeding,shorter hospitalization time,faster recovery etc.It was worthy to be popularized in primary hospital.

BACKGROUND:Studies have shown that neural stem cel transplantation has a certain effect on neuropathic pain, but the efficacy of transplanted cel number on neuropathic pain is not exactly understood. OBJECTIVE:To observe the effect of different amount of neural stem cels administered intrathecaly on the neuropathic pain and expression of glial-derived neurotrophic factor in the spinal cord dorsal horn and dorsal root ganglion in rats after partial sciatic nerve transaction. METHODS:A Sprague-Dawley rat at 14-16 days of pregnancy was used to prepare neural stem cel suspensions that were injected intrathecaly into rat models of partial sciatic nerve transaction at doses of 1×103, 1×104, 1×105, 1×106, 1×107cels per 30 μL, respectively. Additionaly, model group and sham-operated group were set up. Threshold values of mechanical and thermal pain were recorded 1 day before operation, 1, 3, 7, 14, 21 days after operation. Expressions of glial-derived neurotrophic factor protein and mRNA in the ipsilateral spinal cord dorsal horn and dorsal root ganglion were detected by immunohistochemistry and RT-PCR, respectively, at 7 and 21 days after partial sciatic nerve transaction. RESULTS AND CONCLUSION: Pain threshold values were decreased in al the groups except the sham-operated group at 1 day after operation, and reached the peak at 7 and 14 days after operation (P < 0.05). Compared with the model group, the pain threshold values and the expression of glial-derived neurotrophic factor protein and mRNA in the ipsilateral spinal cord dorsal horn and dorsal root ganglion were increased gradualy in a dose-dependent manner in the 1×104, 1×105, 1×106, 1×107 groups at 7 days after operation (P < 0.05). At 21 days post-operation, the pain threshold values showed no differences from the preoperative findings in the 1×105, 1×106, 1×107 groups, but the expression of glial-derived neurotrophic factor was significantly higher in the 1×105 group than the other groups (P < 0.05). Taken together, intrathecal transplantation of neural stem cels at a dose of 1×105 is the most effective in aleviating partial sciatic nerve transaction-induced neuropathic pain in rats.
