Chinese Journal of Pathophysiology 1989;0(06):-
AIM:In order to study the effects of retinal glial cells on glaucomatous retinal ganglion cells damage,expression of TNF-? and TNF-R1 in retinal glial cells was observed in rat model with chronic elevated intraocular pressure glaucoma.METHODS:(1)Rats were rendered elevated intraocular pressure by ligating 2 episcleral veins with subconjunctival injection of 5-Fu.(2)Four weeks after operation,immuno-histological assays were carried out on cryostat sections.The co-expressions of TNF-?-GFAP,TNF-?-OX42,TNFR-1-GFAP,and TNFR-1-NeuN were observed via a confocal laser scanning microscope,respectively.RESULTS:(1)Elevated intraocular pressure was consistently maintained for up to 4 weeks in model group.(2)The co-expressions of TNF-? and GFAP,TNF-? and OX42 were detected in retina in treatment group,respectively.(3)The co-expressions of TNFR-1 and GFAP were also detected in retina,but the co-expressions of TNFR-1 and NeuN were not detected in retina in treatment group.CONCLUSION:TNF-? that activated retinal glial cells may play an important role in glaucomatous retinal ganglion cell damage.

Objective To compare the glycemic control of different management approaches in type 1 diabetic mellitus (T1 DM) children,and to evaluate the influence factors associated with glycemic control.Methods This survey included 68 T1DM children from January 2012 to December 2014 in the Affiliated Hospital of Qingdao University of more than 1 year management.Hemoglobin A1c (HbA1c) levels were detected to assess glycemic control.Twenty-three T1DM children who participated in the World Diabetes Foundation(WDF) management program (group A) were compared with 45 T1DM children who were managed by themselves (group B).The clinical data were analyzed to explore the correlations with glycemic control.Results The HbA1c of 68 children was (8.86 ± 2.00)%,and only 21 cases (30.9%) had optimal HbAlc (HbAlc < 7.5%).The level of HbA1 c of group A (7.60 ± 1.57)% was significantly lower than that of group B[(9.40 ± 1.91) %] (t =-4.045,P =0.001).Group A had less fluctuation in blood glucose than group B,which the duration more than 3 years.Duration (F =2.277,P =0.004),frequency of self-monitoring blood glucose (F =9.375,P =0.001),diabetic education (F =3.276,P =0.002),and diabetic diet (t =-2.046,P =0.025) were associated with glycemic control.Conclusions The glycemic control of T1 DM children at the Affiliated Hospital of Qingdao University was at the medium level,most of them haven't reached the target levels.The WDF management program could significantly and continuously monitor the glycemic level.Diabetic education and more frequent self-monitoring blood glucose and diabetic diet are associated with better glycemic control.

Aim To develop a sensitive, rapid and ac-curate LC-MSn method for determination of midazolam/1′-hydroxymidazolam and their pharmacokinetic char-acteristics in rat brain. Methods SD rats received in-travenous injection of midazolam ( 5 mg · kg-1 ) via femoral vein, a probe drug of cytochrome P450 3A. The microdialysis ( MD ) samples in situ brain were collected every 8 mins at 2. 0μl·min-1 in 2. 4 hours. Analytes in brain dialysate were quantified by the pro-posed LC-MSn method. Gradient elution was performed on an Agilent Eclipse Plus-C18 column ( 2 . 1 × 50 mm, 3. 5 μm). The mobile phase consisted of 2 mmol ·L-1 ammonium acetate and acetonitrile. The analyte was detected using electrospray ionization ( ESI ) in multiple reaction monitoring ( MRM) modes. The reac-tion selected ions were 326 . 1/291 . 1 m/z for midazo-lam, 342. 1/324. 1 m/z for 1′-hydroxymidazolam and 285. 1/154. 0 m/z for diazepam as internal standard. Result The linear ranges of midazolam and 1′-hydroxymidazolam were 0 . 78~100 and 0 . 195 ~12 . 5μg·L-1 respectively. The lower limit of quantification was 0 . 2 μg · L-1 . The RSD of intra- and inter-batch precisions was less than 7 %. The RSD of accuracy was from -1 . 34 to -8 %. Conclusion This sensi-tive and rapid LC-MSn method is suitable for determi-nation of midazolam/1′-hydroxymidazolam in rat brain dialysate. MD combined with LC-MSn method may give assistance to deep and further studies of drug metabo-lism and CYP3A enzyme in brain.

Objective To investigate the value of multi-slice spiral computed tomography (MSCT) in diagnosing gastric cancer. Methods The MSCT signs of 48 gastric cancers proved histologically were evaluated retrospectively. Results The main CT signs included thickening of gastric wall and mass.The lesion showed marked enhancement in the arterial and portal venous phases, and 35 cases showed marked enhancement in the portal venous phase compared with the arterial phase. 12 cases had tumor invasion in the adjacent organs and lymph mode metastasis, and 11 cases had tumor distant metastasis. The accurate rate of enhancement staging was 87 5%. Conclusions MSCT enhancement scan can help us evaluate the lesion more perfectly, and also is helpful in diagnosing and staging of gastric cancer.

Objective To assess the efficacy of dorsal vein complex(DVC)ligation free in laparoscopic radical prostatectomy. Methods The data of 25 patients underwent laparoscopic radical prostatectomy that performed by the same surgeon in our hospital from January 2012 to January 2014 were retrospectively analyzed. Among them,14 cases underwent sutured DVC,11 cases received sutured DVC. Results All the operations were completed with laparoscope and without convert to open surgery. The mean operation time was 246±24.7 min and 236±26.1 min in DVC liga?tion and DVC ligation free,the blood loss was 337.5±120.2 mL and 322.2±104.9 mL in DVC ligation and DVC ligation free,the blood transfusion rate was 14.3%and 18.2%in DVC ligation and DVC ligation free ,the urinary incontinence rate of 6 months after operation was 21.4%and 9.1%in DVC ligation and DVC ligation free,no significant difference was found in the operation time,blood loss,blood transfusion rate and urinary in?continence rate among the two groups(P>0.05). Conclusion DVC ligation free is a safe and effective technique during laparoscopic radical prostatectomy and may simplify the operative procedure and without increase of the risk of bleeding ,which can be more conducive to the early re?covery of postoperative urinary control.
