Objective To investigate the effect of methylprednisolone pulse therapy on spinal nerve functions in patients with acute spinal cord injury (ASCI) and evaluate its safety. Methods 200 patients with ASCI treated in our hospital from January 2010 to December 2016 were selected and were randomly divided into two groups,with 100 cases each group. The patients in control group were treated with routine basic treatment while patients in the study group were treated with methylprednisolone pulse therapy. On the basis of the American spinal cord injury Society scoring criteria (ASIA), the neurological functional recovery scores were performed were scored before and 6 weeks after treatment between the two groups and the adverse reactions were recorded. Results The scores of sensory and motor function of the patients in the two groups were higher than those before the treatment and there was statistical difference (P<0.05), and the scores in the study group was significantly higher than those in the control group, and the difference between the two grouPs was statistically significant (P<0.05). The incidence of adverse reactions in the study group (25.00％) was significantly higher than that in the control group (10.00％), and the difference was statistically significant (P<0.05). The incidence of lung infection and gastrointestinal reaction in the study group were significantly higher than those in the control group and there were statistical difference (P<0.05). Conclusion Methylprednisolone pulse therapy has significant effect on the recovery of neurological function in patients with ASCI, but the incidence of adverse reactions is high, so it is necessary to strengthen the monitoring and intervention in clinic.

Objective To explore the clinical effect of laparoscopic colorectal radical resection combined with simultaneous laparoscopic or open major hepatectomy for synchronous colorectal liver metastases (SCRLM).Methods The retrospective cohort study was adopted.The clinical data of 14 patients with SCRLM who were admitted to the Peking University Third Hospital from July 2010 to September 2015 were collected.Seven patients undergoing total laparoscopic colorectal radical resection combined with major hepatectomy (TLCRMH) were allocated into the TLCRMH group and 7 patients undergoing laparoscopic colorectal radical resection combined with open major hepatectomy (LCROMH) were allocated into the LCROMH group.The statuses of colorectal cancer and metastatic lesions were detected by endoscopy and imaging examination,and diagnostic and therapeutic plans were confirmed through the consultation of muhidisciplinary team.During the hepatectomy,total liver ultrasonography was performed and the extent of liver resection was above 3 hepatic segments.The follow-up of outpatient reexamination was applied to all the patients once every 3 months within postoperative year 2 and once every 6 months after 2 years till December 2015.(1) During operation,method of liver resection,radiofrequency ablation (RFA),operation time,volumes of intraoperative blood loss and blood transfusion,pathological results of primary lesions (T stage,N stage,nerve invasion and canalis haemalis invasion) were collected.(2) After operation,duration of intensive care unit (ICU) care,time for fluid diet intake,postoperative alanine transaminase (ALT),total bilirubin (TBil),complications and duration of hospital stay were collected.(3) Survival of patients and recurrence of tumor were followed up.Count data were analyzed by the chi-sqaure test.Measurement data with normal distribution were presented as x ± s and analyzed using the t test.Measurement data with skewed distribution were described as M(Qn) and M(range) and analyzed using the Mann-Whitney U test.The survival curve was drawn by the Kaplan-Meier method,and overall survival rate and tumor-free survival rate were calculated.The survival analysis was done using the Log-rank test.Results (1) The status of operation:1 and 6 patients in the TLCRMH group underwent respectively left and right hemihepatectomies and 7 patients in the LCROMH group underwent right hemihepatectomy.Four and 6 patients in the TLCRMH and LCROMH groups received local resection of liver metastatic lesions or RFA at segment Ⅱ,Ⅲ or Ⅳ of liver,respectively.The operation time,volumes of intraoperative blood loss and blood transfusion were (651 ± 218)minutes,(1 387 ± 871)mL,(914 ±641)mL in the TLCRMH group and (535 ± 83) minutes,(1 357 ±991)mL,(857 ± 360) mL in the LCROMH group,respectively,with no significant difference between the 2 groups (t =1.320,0.060,0.206,P ＞ 0.05).The numbers of patients in T2,T3,T4,N0,N1,N2 stages,with nerve invasion and canalis haemalis invasion were 1,5,1,3,4,0,3,2 in the TLCRMH group and 0,4,3,1,4,2,2,3 in the LCROMH group,respectively,showing no significant difference between the 2 groups (x2=2.111,3.000,0.311,0.311,P ＞ 0.05).(2) After operation,time for fluid diet intake,ALT,TBil,number of patients with complications and duration of hospital stay were (4.3 ± 1.0) days,(105 ± 47) U/L,(34 ± 25) μmol/L,3 (Ⅲ a,Ⅲ b and Ⅳ a grades of Dindo-Clavien grade),(27 ± 21)days in the TLCRMH group and (4.3 ± 1.1)days,(113 ± 57)U/L,(26 ± 11) μmol/L,4 (Ⅰ,Ⅰ,Ⅱ and Ⅳ a grades of Dindo-Clavien grade),(19 ± 9)days,respectively,showing no significant difference between the 2 groups (t =0.079,-0.286,0.806,X2 =0.286,t =0.856,P ＞ 0.05).The duration of ICU care in the TLCRMH and LCROMH groups were (2.1 ± 1.6) days and (1.0 ± 0.6) days,with a significant difference between the 2 groups (t =1.804,P ＜ 0.05).(3) The status of follow-up:all the patients were followed up for 3-54 months,and the median follow-up time was 15 months (range,3-39 months) in the TLCRMH group and 30 months (range,11-54 months) in the LCROMH group.The 1-,3-year overall survival rates were 100.0％ and 100.0％ in the TLCRMH group and 85.7％ and 64.3％ in the LCROMH group,respectively,showing no significant difference between the 2 groups (x2 =0.676,P ＞ 0.05).The postoperative 1-,2-year cumulative tumor-free survival rates and overage cumulative tumor-free survival time were 64.3％,64.3％ and 20.5 months in the TLCRMH group and 42.9％,14.3％ and 10.9 months in the LCROMH group,respectively,showing no significant difference between the 2 groups (x2=3.160,P ＞ 0.05).Conclusion TLCRMH is safe and feasible for patients with SCLM,and it is comparable with LCROMH in the incidence of postoperative complication and long-term outcomes.

AIM: To observe the clinical effect of amniotic membrane transplantation and penetrating keratoplasty in the treatment of atheromatous corneal ulcer.
METHODS: Thirteen patients ( 13 eyes ) diagnosed atheromatous corneal ulcer from February 2009 to May 2014 in our hospital were retrospectively analyzed. Surgical treatment including amniotic membrane transplantation and penetrating keratoplasty were used to deal the patients with no effects of drugs. All patients were followed up for 4mo to 2a ( mean 8mo ) after surgery. Visual acuity, healing and recipient of ulcer were examined.
RESULTS:There patients were treated conservatively with corneal ulcer slowly healing, healing time was 14~35 ( 21±12. 1 ) d. Seven cases were treated with amniotic membrane transplantation, 2 cases were treated with penetrating keratoplasty, 1 case of corneal ulcer perforation and lost light perception received enucleation of eyeball. Corneal ulcer were cured in patients performed amniotic membrane transplantation and penetrating keratoplasty. All patients had no recurrence during the follow-up period.
CONCLUSION:Atheromatous corneal ulcer is difficult to be cured by conservative treatment. Most patients need operation treatment. Amniotic membrane transplantation and penetrating keratoplasty can be performed to deal with atheromatous corneal ulcer and abtain satisfactory effect. But amniotic membrane transplantation is relatively simple and easy, and it is suitable for promotion in primary hospitals.

AIM: To investigate the preliminary clinical observation of excimer laser phototherapeutic keratectomy ( PTK ) assisted by anterior segment optical coherence tomography ( OCT ) in the treatment of non II type granular corneal dystrophy.
METHODS: A retrospective case series were studied. Totally 8 patients ( 12 eyes ) who were diagnosed as granular corneal dystrophy underwent PTK from April 2011 to January 2013 in our hospital. All patients were excluded from the II type granular corneal dystrophy ( Avellino corneal dystrophy ) by the Avellino corneal dystrophy rapid diagnostic kit and underwent preoperative anterior segment OCT examination, so as to determine the lesion morphology and depth, and used to guide the setting of PTK parameters. They were followed up for the complications after operation, postoperative recurrence, the recovery of visual acuity.
RESULTS: All patients were followed up for 6-12mo, average 9mo after operation. All patients' best corrected visual acuity were significantly improved, superficial corneal opacity lesions were effectively removed, and the corneal opacity recurrence or serious Haze were not found during the follow-up period after operation.
CONCLUSION: In patients with non type II granular corneal dystrophy, PTK assisted by anterior segment OCT can be accurate, effective removal of corneal lesions, obtain good effect after operation.

Objective To investigate the effects of penehyclidine (PHCD) pretreatment on nuclear factor kappa B ( NF-kB ) activity during lipopolysaccharide ( LPS )-induced acute lung injury ( ALl ) in neonate rats.Methods Thirty 7-day old Wistar rats of both sexes weighing 18-21 g were randomly divided into 3 groups ( n =10 each): group Ⅰ control (group C); group Ⅱ LPS; group Ⅲ PHCD. Group Ⅱ and Ⅲ received intraperitoneal ( group IP) LPS 3 mg/kg. In group Ⅲ PHCD 5 mg/kg was administered IP at 30 min before LPS respectively. The animals were killed at 4 h after LPS administration. The lungs were immediately removed. The W/D lung weight ratio was measured. The TNF-α, IL-1 βand IL-10 content in the lung were detected by ELISA and expression of NF-kB p65 was detected by immuno-histochemical staining.Results LPS significantly increased W/D lung weight ratio, TNF-α, IL-1 β, IL-10 content and NF-kB p65 expression in the lung as compared with control group. PHCD administered before LPS significantly attenuated the LPS-induced changes. Electron microscopy showed that PHCD before LPS significandy ameliorated the LPS-induced histological damages. Conclusion Pretreatment with PHCD can attenuate LPS-induced acute lung injury though inhibition of NF-kB activation and inflammatory response of lung tissue in neonate rats.

Objective To investigate the effects of lappaconitine on the perioperative immune function.Methods Twenty-four ASA I or II patients aged 23-64 yr undergoing elective radical mastectomy (8 patients),iaminectomy and vertebral canal decompression (8 patients) or femoral head replacement (8 patients ) were randomly divided into 2 groups (n=12 each): control group (C) and lappaconitine group (L).In group L ondansetron 4 mg was given IV and lappaconitine 8 mg was infused IV over 30 rain before induction of anesthesia.In group C equal volume of normal saline was infused instead of lappaconitine.Anesthesia was induced and maintained with propofol,remifentanil and rocuronium.Lappaconitine 0.28 mg/ml was continuously infused at 2 ml/h after induction of anesthesia in group L.When the patients recovered from anesthesia after operation,PCA with 0.28 mg/ml lappaconitine was started (background infusion 2 ml/h,bolus dose 0.5 ml and lockout interval 15 min).In group C pethidine 50 mg and droperidol 2.5 mg were given IM on demand.Venous blood samples were taken at 30 rain before induction of anesthesia(T1,baseline),immediately (T2) and at 24 h(T3) and 48 h (T4)after operation for determination of TNF-α,IL-2,IFN-γ and sIL-6R concentration by ELISA.CD3,CD4,CD8 and NK cell expression was determined using flow cytometry and the ratio of CD4/CD8 was calculated.The concentrations of IgA,IgM,IgG,CD3 and CD4 were determined by radioimmunoassay.Results Plasma SIL-6R and TNF-α concentrations were significantly lower while IL-2,IgA,IgG,IgM concentrations and CD4/CD8 ratio were significantly higher after operation in group L than in group C.Conclusion Lappaconitine can improve perioperafive humoral immune function thus contributing to its analgesic and anfi-inflammatory effects.

Objective To study the correlation of the level of high-sensitivity C-reactive protein (Hs-CRP) in the acute phase of ischemic stroke and progressive stroke. Methods 101 patients with acute ischemic stroke were collected. Serum Hs-CRP of all patients were measured at 24 hours after admission , the onset of 48 hours, the onset of 72 hours by latex enhanced immune turbidity method. According to their serum Hs-CRP lev-els, the patients were divided into the group of Hs-CRP sustained growth (n = 35) and the group of non Hs-CRP sustained growth (n = 66). The NIHSS scores were assessed on two groups of patients , Logistic regression analysis was made to screen the related factors of Hs-CRP increase and the possible risky factors for progressive ischemic stroke. Results There was a significant difference of serum Hs-CRP level between the two groups (P <0.001). The incidence of progressive stroke in the group of Hs-CRP sustained growth was significantly higher than that in the group of non Hs-CRP sustained growth (χ2 = 32.710, P < 0.001). Logistic regression analysis showed blood glucose , white blood cell count , triglyceride level and NIHSS scores at admission were associated with sustained growth of Hs-CRP and the factors that they included Hs-CRP sustained growth , admission NIHSS scores, diabetes mellitus and pulmonary infection were regarded as independent risk factors. Conclusion The sustained growth of Hs-CRP in the acute phase of ischemic stroke is an independent predictor of progressive stroke.
