Chinese Journal of Cerebrovascular Diseases 2009;6(9):471-474
Objective: To identify the risk factors of fever in critically ill patients with acute stroke in a neurological intensive care unit (NICU). Methods: The frequency of risk factors of fever in 137 stroked patients during the first 7. days after admission were retrospectively studied. Fever was defined as a patient's axillary temperature ≥37.5°C in two separate determinations or >37.8°C in one determination. We categorized the fever into 4 kinds: Circled digit oneany fever, Circled digit twoexplained infectious fever, Circled digit threeexplained noninfectious fever and Circled digit fourunexplained fever based on Commichau's methods. Then logistic regression analysis was used to ascertain the risk factors of the 4 kinds of fever. Results: Any fever, explained infectious fever, unexplained fever and explained noninfectious fever occurred in 65%, 48.9%, 15.3% and 0.7% respectively. Multivariable logistic regression analysis demonstrated that patients older than 65 years, impaired consciousness, large area cerebral infarction/cerebral hemorrhage volume ≥30 ml, and deep vein catheterization used were involved into regression equation for any fever. In addition to these variables, length of NICU stay was also involved into regression equation for explained infectious fever. Brain midline shift, initial peripheral leucocytes count more than 12.0 × 10 9/L were involved into regression equation for unexplained fever. Conclusion: The risk factors differ in various kinds of fever in critically ill patients with acute stroke. Effective measures should be taken for different types of febrility.

Objective: To investigate the application of the calculated electrophysiological parameters in early
diagnosis of carpal tunnel syndrome (CTS). Methods: 44 patients (60 hands) with a diagnosis of
CTS and 31 healthy volunteers (44 hands) were enrolled. Acquired indicators include median nerve
distal motor latency (DML), complex muscle action potential (CMAP) amplitude, conduction velocity
(MCV), median nerve sensory nerve action potential (SNAP) amplitude, and conduction velocity
(SCV). Then the terminal latency index (TLI), the residual latency (RL), and the difference in peak
sensory latencies between the median and ulnar nerves (ΔPSL) were calculated. Results: The two
groups were matched in age and gender distribution. The CTS group showed significant difference
in SCV, DML, SNAP, and CMAP compared with the control group. The sensitivity, specificity, cutoff value, Youden index, and area under the curve of each indicator are respectively as follows: TLI
(0.733, 0.932, 0.622, 0.629, and 0.877), RL (0.750, 0.977, 1.334, 0.727, and 0.907), ΔPSL (0.950,
0.841, 0.150, 0.791, and 0.942), SCV (0.950, 0.796, 56.5, 0.746, and 0.946), DML (0.867, 0.932,
3.55, 0.799, and 0.930), SNAP (0.683, 0.932, 21.68, 0.615, and 0.844), and CMAP (0.683, 0.773,
8.76, 0.456, and 0.758).
Conclusion: The calculated electrophysiological parameters have higher sensitivities and specificities
relative to a single electrophysiological parameter, which could greatly improve the accuracy of early
diagnosis of CTS.

AIM:To investigate the effects of amnion epithelial cell ( AEC) suspension liquid on the biological behavior of the rabbit's corneal epithelium, combined with the in vitro and in vivo experiments. · METHODS: The rabbit's corneal epithelium were cultured in the lower chamber of transwell, and AEC suspension liquid was dropwised in the upper chamber. There was only culture medium in the upper chamber of the control group. The proliferation of rabbit's corneal epithelium was observed with CCK-8 automated colorimetry and the expression of PCNA was detected by immunocytochemistry. We used the scratch wound assay to detect the migration of corneal epithelial cell ( CEC ) . The in vivo models were established by placing a 10mm diameter corneal trephine in the center of the cornea, within 1mol/L NaOH for 1min. We divided those into three groups: treatment group of AEC suspension liquid eye drop, AEC suspension liquid subconjunctival injection and the control group without any treatment. Using the slit- lamp biomicroscope and fluorescence staining to observe the cornea per week. After 28d we took the eyeballs with the HE staining. The expression of VEGF was detected by immunohistochemistry. ·RESULTS: The activity of CEC with AEC treatment was much higher than the control group ( P< 0. 05 ). The expression of PCNA increased in AEC group (P<0. 05). And the migration of CEC in the AEC group was faster than the control one. In vivo, the inflammation of the corneal and the CNV of the AEC group were all significantly reduced compared with the control group (P<0. 05 ). There were less invasive cells and more ordered organization arrangement in ACE group observed by the HE staining. The expression of VEGF and mcp-1 in these two AEC treatment groups all significantly decreased compared with the control group (P<0. 05). ·CONCLUSION: AEC suspension liquid can promote the proliferation and migration of the rabbit's corneal epithelium. The potential of AEC suspension liquid as a therapy for acute corneal alkali burn.

OBJECTIVETo observe improved effects of Jingjin acupuncture on fine activity of hemiplegic hand in recovery period of stroke.
METHODSFifty cases were randomly divided into an observation group and a control group, 25 cases in each one. Regular western medicine treatment, rehabilitation training and regular acupuncture (in which Shuigou (GV 26), Baihui (GV 20), Neiguan (PC 6), etc. were selected) were applied in both groups. Additionally, muscles in palm side of affected hand, dorsal metacarpophalangeal joints and proximal interphalangeal joints were treated with acupuncture in the observation group, once every other day and electroacupuncture was applied when arrival of qi was acquired. Baxie (EX-UE 9) in the affected hand were needled in the control group, and electroacupuncture was added when arrival of qi was acquired. Ten days of treatment was considered a treatment course, and after two courses Lindmark score, Brunnstrom movement function grade, joint range of hand and Barthel index (BI) were observed in two groups.
RESULTSCompared before the treatment, the Lindmark score in two groups were both improved after the treatment (both P < 0.01). Compared with the control group, the motor coordination ability, sensory function and total score of Lindmark in observation group were obviously improved (differences before and after treatment: 8.24 +/- 3.07 vs 6.84 +/- 2.43, 3.52 +/- 2.33 vs 2.16 +/- 2.12, 11.76 +/- 3.55 vs 9.00 +/- 3.62, all P < 0.05). The Brunnstrom movement function grade was significantly improved in both groups after treatment (both P < 0.01), which was more obvious in the observation group (P < 0.05). The joint range of hemiplegic hand was improved in both groups after treatment (both P < 0.01), which was more obvious in the observation group [differences before and after treatment: (25.35 +/- 10.91) degrees vs (18.65 +/- 7.86) degrees, p < 0.05]. The score of BI was also significantly improved after treatment in two groups (both P < 0.01).
CONCLUSIONThe Jingjin acupuncture could effectively improve fine activity of hemiplegic hand in recovery period of stroke prove daily life ability.

The study aims to develop an LC-MS/MS method for the simultaneous determination of amygdalin and paeoniflorin in urine samples, and to investigate their urinary excretion characteristics in healthy volunteers after intravenous infusion administration of Huoxue-Tongluo lyophilized powder for injection (HTLPI). The urine samples were extracted by methanol, and then separated on a Hedera ODS-2 column with a mobile phase of acetonitrile and 5 mmol · L(-1) ammonium acetate buffer solution containing 0.05% formic acid (20:80). Electrospray ionization source was applied and operated in the positive ion mode using MRM. The method exhibited good linearity over the concentration range of 0.03 -40 µg · mL(-1). The values on both the occasions (intra- and inter-day) were all within 15% at three concentration levels. No matrix effect and carry-over effect were observed. Amygdalin and paeoniflorin were stable in human urine under different storage conditions. Approximately 79.6% of the administered amount of amygdalin was excreted unchanged in urine within 24 h and which was 48.4% for paeoniflorin. The developed LC-MS/MS method can be applied to evaluate the urinary excretion of amygdalin and paeoniflorin.
