Objective To summarize the experiences of microsurgery for treatment of middle cerebral artery aneurysms (MCAA). Methods The clinical data of 35 patients with MCAA treated by microsurgery in General Hospital of PLA from 2004 to 2008 were retrospectively reviewed. Of them there were 20 males and 15 females, aged 18 to 72 years with a mean of 40 years. Of the 35 patients, subarachnoid hemorrhage occurred formerly in 22, intracerebral hemorrhage occurred in 11 and subdural hematoma in one patient. The MCAA located in the middle cerebral artery trunk in 10 patients, at the bifurcation in 20 patients (including one patient with 2 MCAAs), and in the distal segment in 5 patients. MCAA located on the left side in 13 and on right side in 22 patients. There were 7 patients with giant aneurysms, 11 with large aneurysms and 17 with small aneurysms. Microneurosurgery was performed in all cases, and different approaches were taken according to the locations of aneurysms. Superior temporal gyrus approach was conducted in 3 patients with giant intracerebral hematoma. Bypass of superficial temporal artery to middle cerebral artery was performed before occlusion of the afferent artery in one patient with giant aneurysm. Bypass with saphenous vein to middle cerebral artery was performed in another patient with giant aneurysm. Results The giant and large MCAAs consisted of 51.4% of all cases. Excellent outcomes were achieved in 20 patients, no marked change in 12 patients, and post-operative complications were observed in 3 patients. No perioperative death occurred. Conclusions Giant and large aneurysms are more common in middle cerebral artery aneurysms. Proper surgical approaches based on different situations during operation should be considered to achieve satisfactory outcome.

Objective To evaluate the diagnostic performance of Xpert MTB/RIF for the diagnosis of tuberculous meningitis (TBM).Methods This was a prospective, single center clinical trial.A total of 116 consecutive patients with suspected meningitis who were admitted to Xijing Hospital from October 2013 to June 2015 were recruited.Mycobacterium tuberculosis ( MTB) and rifampicin ( RIF) resistance mutations in 1 ml cerebrospinal fluid ( CSF) were detected with Xpert MTB/RIF and the remaining sample was tested by Ziehl-Neelsen staining , MGIT960 liquid culture and other laboratory tests .And the enrolled patients were grouped according to the 2010 South African expert consensus .The diagnostic performance of Xpert MTB/RIF was evaluated by comparing against clinical score >5 points and MGIT960 liquid culture as reference standards respectively .The comparison was performed using a χ2 test or Fisher′s exact test for categorical variables and a nonparametric rank sum test for continuous variables .Results Among the enrolled 116 subjects, 23 subjects were diagnosed as definite-TBM by MGIT960 liquid culture, 16 subjects were classified as probable TBM , 27 subjects were classified as possible TBM , and 50 subjects were classified as non-TBM.When clinical score >5 points was used as a reference standard , the sensitivity of Xpert MTB/RIF (39.4%) was comparable with that of MGIT960 liquid culture (34.8%) (χ2 =0.292, P=0.589), and significantly better than that of Ziehl-Neelsen staining (9.9%) (χ2 =16.500, 12.771, P<0.001). No significant differences were found among the specificities of Xpert MTB /RIF, MGIT960 liquid culture and Ziehl-Neelsen staining ( 98.0%, 100.0% vs 98.0%, χ2 =1.014, P=0.602 ) .When tested against MGIT960 liquid culture as a reference standard , the sensitivity of Xpert MTB/RIF was 91.3%. Conclusions Xpert MTB/RIF is a rapid and specific method to detect MTB and RIF resistance in CSF .It exhibits a good rule in value for the diagnosis of TBM and a comparable sensitivity with MGIT 960 liquid culture, thus it can be used as the initial method for the diagnosis of tuberculous meningitis .

Objective To investigate the effects of intrathecal administration of Maresin 1 on pain behavior and glial cells activation in spinal dorsal horn of mice with bone cancer pain(BCP).Methods Experiment Ⅰ,twenty-eight clean male C57BL/6 mice,aged 4-6 weeks,weighing 18-22 g,were ran-domly divided into two groups:sham 1 group(group S1)and BCP 1 group(group B1),14 mice in each group.BCP model was established in group B1 by injecting PBS 20 μl containing 2 × 105 lewis lung carcino-ma cells into the intramedullary space.Group S,received PBS 20 μl without tumor cells.Six mice in each group were randomly selected to determine the mechanical withdrawal threshold(MWT)and thermal with-drawal latency(TWL)1 day before implantation,3,7,14,21 days after implantation.Four mice were randomly sacrificed on days 7,14 and 21 in group S,and group B1.The expressions of spinal glial fibrillary acidic protein(GFAP)and ionized calcium-binding adapter molecule 1(Iba1)were detected by Western blot.Experiment Ⅱ,thirty-six clean male C57BL/6 mice were randomly divided into three groups:sham 2 group(group S2),BCP 2 group(group B2),and Maresin 1 group(group M),12 mice in each group.BCP models were established in groups B2 and M while group S2 received PBS 20 μl without tumor cells.Maresin 1 50 ng/5 μl were intrathecally injected from days 14 to 16 after tumor cells implantation.Six mice in each group were randomly selected to determine the MWT and TWL on days 14 to 18 after implantation.Mice were sacrificed on day 18 after pain behavior tests.The expressions of spinal GFAP and Iba1 were de-tected by Western blot and immunofluorescence staining.The levels of spinal IL-1 β,IL-6,and TNF-α were detected by ELISA.Results Experiment Ⅰ:compared with group S1,the MWT and TWL were significantly lower on days 7,10,14,and 21 after implantation in group B,(P＜0.05),the expressions of spinal GFAP and Iba1 were upregulated on days 7,14,and 21 after implantation in group B1(P＜0.05).Experiment Ⅱ:compared with group S2,the levels of spinal GFAP,Iba1,IL-1β,IL-6,and TNF-α were increased on day 18 after implantation in group B2(P＜0.05).Compared with group B2,the MWT and TWL were significantly higher on days 15-18 after implantation while levels of spinal GFAP,Iba1,IL-1β,IL-6,and TNF-α on day 18 were decreased in group M(P＜0.05).Conclusion Intrathecal administra-tion of Maresin 1 attenuates BCP maybe by inhibiting the glial cells activation and neuroinflammation in the spinal cord.

OBJECTIVETo study the ethylene responsive element binding protein genes of Salvia miltiorrhiza through bioinformatics and characterization of its tissue expression in regenerated plantlets.

METHODThe ethylene responsive element binding protein genes were obtained by cDNA microarray analyze. BLAST was used for alignment, ORF finder software was used to find open reading frame, Prosite database was used to analyze the protein. Semi-quantitative RT- PCR method was used to detect the gene expression level.

RESULTOne ethylene responsive element binding protein was obtained, named as SmERF. SmERF had an open reading frame of 699 bp with 5'-URT 87 bp and 3'-URT 166 bp. The putative protein SmERF contains a highly conserved ERF/AP2 domain. Semiquantitative RT- PCR illustrated that SmERF was expressed in all tissues such as root, stem and leaf in regenerated shoots, while the expression level was higher in root than in stem and leaf.

CONCLUSIONIt was the first time to obtain ERF gene in S. miltiorrhiza and set a good foundation for its further functional study.

Objective To observe the effect of low-dose remifentanil combined with propofol on the blood pressure(BP),heart rate(HR)and neonatal Apgar score in parturients undergoing cesarean section. Methods Forty-two parturients undergoing cesarean section were placed in two groups:low-dose remifentanil combined with propofol general anesthesia group(group GA,n=20)and neuraxial anesthesia group(group RA, n=22).BP and HR at the basis line(T0),pre-incision(T1),instant incision(T2),1 min(T3),3 min(T4),5 min(T5)after incision,cutting the umbilical cord(T6)were recorded,and neonatal Apgar scores at 1 min and 5 min after birth were also recorded. Results In group GA,the systolic blood pressure(SBP)and the diastolic blood pressure(DBP)remained unchanged at any time(P > 0.05). Compared with T0,HRs at T1~ T4were de-creased significantly(P<0.05).In group RA,compared with T0,the levels of SBP,DBP,HR at T1~T4were de-creased significantly(P<0.05).The levels of SBP and DBP at T1~T4in group GA were significantly higher than those in group RA(P<0.05),but there was no significant difference in HR between the two groups(P>0.05). The number of cases of ephedrine in group RA was significantly larger than that in the group GA(P<0.05).Neo-natal Apgar scores at 1 min and 5 min after birth were similar between the two groups(P > 0.05). Conclusion The application of low-doseremifentanil and propofol can be safely used in cesarean section,for the stability of par-turient BP and HR and no risk of neonatal respiratory depression.

To explore the method of identifying nursing-related patient safety events,types,contributing factors and evaluate consequences of these events in hospitals of China,incident report program was established and implemented in 15 patient units in two teaching hospitals of China to get the relevant information.Among 2935 hospitalized patients,141 nursing-related patient safety events were reported by nurses.Theses events were categorized into 15 types.Various factors contributed to the events and the consequence varied from no harm to patient death.Most of the events were preventable.It is concluded that incident reporting can provide more information about patient safety,and establishment of a program of voluntary incident reporting in hospitals of China is not only urgent but also feasible.
