AIM: To study the action of NF-?B p65 in tubule-interstitium in rats with active Heymann nephritis(AHN). METHODS: Twenty female Wistar rats in 6-8 weeks of age were divided into two groups. The nephritis was induced with Fx1A/CFA by subcutaneous injection and with CFA as control. After rats were killed, the activation of NF-?B p65 in renal tissue was observed by immune histochemistry. RESULTS: The lesion score of renal interstitium and activation of NF-?B p65 of renal tubule in rats with AHN was higher than those of control group(P

Objective: To study the UPLC-MS fingerprint of Bupleurum marginatum DC. in northwest Hubei and establish the quality evaluation system for the herb. Methods:A UPLC-MS method was used to analyze 10 samples of B. marginatum DC with the following chromatographic conditions:an ACQUITY UPLC? RBEH C18 column (100 mm × 2. 1 mm, 1. 7 μm) was used, the mobile phase consisted of acetonitrile-0. 3% formic acid water with gradient elution, the flow rate was 0. 2 ml·min-1, and the detection wavelength was 203nm with ESI(-). Results:There were 8 common peaks in the UPLC-MS fingerprint of B. marginatum DC. Through analyzing the information of mass spectrometry and combining the references, 6 peaks were identified. Conclusion:The UPLC-MS fin-gerprint method is simple,rapid and feasible. The acquired UPLC-MS fingerprint of B. marginatum DC. and the evaluation indices can provide the scientific quality assessment of B. marginatum DC.

Objective:To evaluate the clinical value of Truview~(TM)EVO_2 optic laryngoscope by comparing it with the Macintosh laryngoscope in patients receiving cervical vertebral surgery.Methods:One hundred patients scheduled for elective cervical vertebral surgery were enrolled in this randomized crossover study.After induction,the patients'glottis in group A (n=50)was displayed by Macintosh laryngoscope and the Cormack-Lehane(C/L)grade was recorded,and then optic laryngoscope was employed to display the laryngeal structure.The order of laryngoscopy attempts was reversed in group B(n= 50).Parameters recorded included demographics,airway assessment feat ures(BMI,thyromental distance,mandibular size,mouth opening,mallampati oropharyngeal scale,and neck movement),C/L grade,laryngoscopic force applied,duration of intubation, difficulties of laryngeal view and injury of upper airway.Results:There were no significant difference in demographics,airway assessment features,C/L grade and duration of intubation between the 2 groups,whereas the laryngoscopic force in group A was significantly lower than that in group B(P

AIM:To investigate the surgical method and extent of reoperation in the concomitant strabismus patients with surgical under-correction and over-correction.
METHODS: Ninety - six concomitant strabismus patients with surgical under - correction and over -correction were recruited in this study, which included 41 males and 55 females, aged 21. 90±14. 70. All individuals underwent routine eye examinations for strabismus before the surgery. Among the cases with concomitant esotropia, there were over-correction in 23 cases, under-correction in 15 cases. Among the cases with concomitant exotropia, there were over-correction in 28 cases, under - correction in 30 cases. The method of reoperation were based on angle of deviation, the method of original operation and acute visual acuity of patients.
RESULTS:In over - correction cases with concomitant esotropia, medial rectus muscle of 9 cases were advanced, the corrective extent was (5. 51±2. 63) ? / mm;9 cases were performed advance of medial rectus muscle and recession of lateral rectus muscle, the corrective extent was (6. 25±1. 59) ? / mm; 3 cases were performed resection of medial rectus muscle and recession of lateral rectus muscle, the corrective extent was (4. 26±1. 04) ? /mm; only 2 cases were performed recession of lateral rectus muscle, the corrective extent was (4. 21±1. 91) ? /mm. In under - correction cases with concomitant esotropia, 6 cases were performed resection of lateral rectus muscle, the corrective extent was (4. 03±0. 98) ? /mm; 6 cases were performed resection of lateral rectus muscle and recession of medial rectus muscle, the corrective extent was (6. 86 ± 1. 32) ? / mm; 3 cases were performed recession of medial rectus muscle, the corrective extent was ( 4. 33 ± 0. 29 ) ? / mm. In over -correction cases with concomitant exotropia, 16 cases were performed advance of lateral rectus muscle, the corrective extent was (5. 37 ± 1. 56) ? / mm; 6 cases were performed recession of medial rectus muscle, the corrective extent was (6. 29 ± 3. 68) ? / mm; 5 cases were performed advance of lateral rectus muscle and recession of medial rectus muscle, the corrective extent was (5. 46±1. 78) ? / mm; 1 case were performed resection of lateral rectus muscle, the corrective extent was 5. 00? / mm. In under - correction cases with concomitant exotropia, 12 cases were performed resection of medial rectus muscle, the corrective extent was (4. 47 ± 0. 54) ? / mm; 16 cases were performed recession of lateral rectus muscle and resection of medial rectus muscle, the corrective extent was ( 5. 11 ± 0. 75 ) ? / mm; 2 cases were performed recession of lateral rectus muscle, the corrective extent was (2. 65±0. 42) ? / mm.
CONCLUSION: In reoperation of concomitant strabismus patients with over-correction, weakening or/and strengthening the horizontal muscle which were performed surgery before has a greater and more unstable surgical corrective extent. While In reoperation of concomitant strabismuspatients with under -correction, weakening or/ and strengthening the horizontal muscle which were not performed surgery has a normal corrective extent as usual.

Neuropathological, clinical epidemiology and animal models studies provide clear evidence for the activation of neuroinflammation in Alzheimer's disease (AD), and long-term use of non-steroidal anti-inflammatory drugs (NSAIDs) is linked with reduced risk to develop the disease. But the clinical trials got a negative outcome with traditional NSAIDs treating AD. The therapeutic effects of NSAIDs on Alzheimer's disease are still not clear based on the present research. Profound study for anti-inflammatory mechanisms and standardized clinical trials are needed. As cause and effect relationships between neuroinflammation and AD are being worked out, the challenge is how to realize the effect of traditional NSAIDs on treating AD.

Objective To investigate the apoptosis of T lymphocytes,the expression of Bcl-2, Fas on the peripheral blood T lymphocytes in end stage renal disease patients;and to explore the characteristics of Th1 /Th2 profile and the influence of dialysis membranes with different permeability on the apoptosis of T lymphocytes of maintenance hemodialysis patients.Methods The study included 10 non-dialyszed (ND)patients,45 maintenance hemodialysis patients with cellulose acetate (CA) membranes(13),low-flux polusulfone(PS-LF) membranes(16),high-flux polusulfone (PS-HF) membranes (16) and 8 healthy volunteers (C).The apoptosis of T lymphocytes,expression of Bcl-2,Fas on peripheral blood T lymphocytes cultured with phytohemagglutinin (PHA) stimulation for 24 hours were measured by flow cytometry and immunohistochemical.ELISA was performed for detecting the levels of IFN-?and IL-4 in culture supematants.Results In ESRD patients,the apoptosis of T lymphocytes was greater than that of group C.Group CA was greater than group PS-HF and group PS-LF (P＜0.05).The expression of Bcl-2 on T lymphocytes in ESRD patients was lower than that of group C (P＜0.05).There was negative correlation between the T lymphocytes apoptosis and Bcl-2. The expression of Fas on T lymphocytes in ESRD patients was greater than that of group C (P＜0.05), and it was positive correlated with T lymphocytes apoptosis.The level of IFN-?of ESRD patients was decreased significantly compared with that in group C (P＜0.05),and there was negative correlation between T lymphocytes apoptosis and IFN-?.IL-4 was increased in ESRD patients (P＜0.05) and it was positive correlated with T lymphocytes apoptosis.Conclusions The accelerated apoptosis of T lymphocytes in ESRD patients may be related to the expression of Bcl-2 and Fas of T lymphocytes.ESRD patients show a suppressed secretion of IFN-?and an increased secretion of IL-4. T lymphocytes apoptosis of maintenance hemodialysis patients is influenced not only by the biocompatibility but also by the permeability of the dialysis membrane.
