Immunohistochemical method was used to investigate the morphology and distribution of the oxytocin immunoreactive (OXT-ir) neurons and their dendrites in the subependymal plexus (SEP) around the third ventricle (OXT-SEP). The OXT-ir neurons were of magnocellular neurosecretory type which often intercalated between the ependymal cells, their dendrites were generally long and straight and mostly paralleled to or traveled within the ependyma,some of them could protrude into the ventricle, and most of them appeared heavily vacuous and have a strong tendency of grouping into fascicles. The plexus was composed of dorsal and ventral parts, the former corresponding to the extent of the magnocellular paraventricular nuclei and was extensive and dense, the dendrites were well organized; the latter was more sparse. The cell bodies and dendrites within and between different parts might mix or contact with each other. The functional significance of the plexus is discussed.

Using immunohistochemical method in the present study we examined the changes of the CGRP-LI nerve fibers in the anterior pituitary (AP) of the rat after adrenalectomy. 60 male adult rats were divided into 5 groups at random, i.e., normal, sham-operated, adrenalectomized (AdX) plus hydrocortisone, normal plus hydrocortisone and AdX groups. There were some of CGRP-LI nerve fibers sparsely and unevenly distributed in the normal rat AP. The fibers which had some varicosities and varied in their thickness could occurred either individually or in plexus. The quantity of CGRP-LI nerve fibers increased in number, length, branches and the density of the varicosities. The extent of their distribution was also enlarged. With a Leitz computer-assisted image analyzer the quantity of the CGRP-LI nerve fibers in the 5 groups was measured and the results showed that the amount of CGRP-LI nerve fibers in AdX group was significantly higher than those in all the other groups (P

OBJECTIVETo investigate the correlation between age and Gleason score (GS) in patients with prostate adenocarcinoma.

METHODSThis study included 674 patients with pathologically confirmed prostate adenocarcinoma. We determined the GS, primary grade, and secondary grade of the cases, and compared them among different age groups.

RESULTSThe mean age of the patients was (70.22 ± 8.26) yr, ranging from 25 to 96 years, (69.06 ± 8.35) yr in those with GS 6, (70.55 ± 8.16) yr in GS 7, (70.99 ± 6.54) yr in GS 8, (71.56 ± 9.18) yr in GS 9, and (72.79 ± 11.36) in GS 10. The mean GS, primary grade, and secondary grade were 7.08 ± 1.09, 3.54 ± 0.72, and 3.53 ± 0.66, respectively, and the mean GSs in the < 60 yr, 60-69 yr, 70-79 yr, and ≥ 80 yr groups were 6.86 ± 1.10, 6.99 ± 1.10, 7.08 ± 1.04, and 7.38 ± 1.23, respectively. Those with GS 6, 7, and ≥ 8 accounted for 37.7%, 34.3%, and 28.0%, respectively. The patients aged < 60, 60-69, 70-79, and ≥ 80 years constituted 10.5% (71/674), 30.6% (206/674), 47.6% (321/674), and 11.3% (76/674), respectively. The age of the patients was significantly correlated with GS (r2 = 0.013, P = 0.003) and the primary grade (r2 = 0.014, P = 0.002), but not the secondary grade (r2 = 0.005, P = 0.055).

CONCLUSIONOf the prostate adenocarcinoma patients, those aged ≥ 70 years form a larger proportion, and those with GS ≥ 7 comprise a higher percentage. The age of the patient is correlated with Gleason score but has a limited value in its prediction.

OBJECTIVETo explore the basic features of the prostate carcinoma Gleason grading system of the International Society of Urological Pathology (ISUP).

METHODSWe analyzed the means and proportions of the Gleason score (GS), primary grade (PG), secondary grade (SG) and third grade (TG) of 667 cases of prostate carcinoma.

RESULTSThe means of GS, PG, SG and TG were 7.06 +/- 1.10, 3.53 +/- 0.66, 3.53 +/- 0.72 and 4.30 +/- 0.96, respectively. The cases with GS 5, 6, 7, 8, 9 and 10 accounted for 0.4% (3/677), 37.2% (252/677), 34.4% (233/677), 13.7% (93/677), 12.0% (81/677) and 2.2% (15/677), respectively; those with GS < or = 6 and > or = 7 constituted 37.7% (255/677) and 62.3% (422/677); those with GS3 + 3, 4 + 3 and 3 + 4 made up 37.2% (252/677), 19.2% (130/677) and 15.2% (103/677); and the TG cases held 10.3% (70/677), including 30.0% (21/70) of grade 3, 10% (7/70) of grade 4 and 60.0% (42/70) of grade 5.

CONCLUSIONOur study showed a high proportion of GS, a low proportion of GS < or = 6, and a high proportion of GS > or = 7 in the ISUP prostate carcinoma Gleason grading system. TG of GS needs to be further understood.

Objective: To determine asperosaponin VI, psoralen, and angelicin in Xianling Gubao Capsules (XGC) via multi- wavelength HPLC method. Methods: Separation was carried out on Welch Ultimate® XB-C18 column. The mobile phase was acetonitrile-water system and a linear gradient elution was used. The column temperature was 30℃. The detection wavelength for asperosaponin VI was set at 212 nm, those for psoralen and angelicin were set at 246 nm. Results: Three components reached baseline separation, the linearity was good when sample volumes were in the ranges of 144.1-5 764.0 for asperosaponin VI (r = 0.999 6), 5.4-215.2 (r = 0.998 0) for psoralen, and 6.6-265.6 ng (r = 0.998 5) for angelicin. The average recoveries of asperosaponin VI, psoralen, and psoralen were 98.11%, 97.86%, and 98.22%, respectively. The RSDs of recoveries were all less than 2.0%. Conclusion: The method is simple and accurate and has good separation, with high sensitivity and good efficiency for the determination of more-index components in XGC.

Objective To discuss the remedy and clinical effect of traumatic splentic rupture.Methods Clinical data of 32 cases of traumatic splentic rupture were retrospective analyzed.Results No dead cases,6 cases were cured by conservative treatment,18 cases were explored by laparoscope,and 14 cases remained spleen,4 cases were converted to traditionary splenectomy.Traditionary splenectomy was done on 8 cases directly.Conclusions Ⅰ,Ⅱ grade of traumatic splentic rupture may choose conservation treatment or remain spleen by laparoscope operation.Splenectomy should be done on Ⅲ,Ⅳ grade of traumatic splentic rupture in time.

Objective To evaluate the influence of pressing technique on the malposition of catheter dur- ing the operation of peripherally inserted central catheter (PICC). Methods Totally, 169 patients with lung cancer were randomly divided into treatment group (n = 88), in which the external and internal jugular veins were pressed at the supraclavicular fossa by the assistant when the catheter was navigated in 25 cm, and control group (n = 81), in which the patients were called to turn their angle of mandible to supraclavicular fossa when the cathe- ter was sent in. Results There were only one patient whose catheter was sent in external jugular vein in treatment group and nine patients whose catheters were sent in external and internal jugular vein in control group. The inci- dence of malposition of catheter was significantly different between two groups (1.1% vs. 11. 1% , X2 =7. 3636, P < 0. 01). Conclusion The pressing technique can reduce the incidence of malposition of catheter into external and internal jugular vein during the operation of PICC.

Objective:To evaluate the specificity and sensitivity of ABI 7000,7300 and 7500 real-time PCR instruments.Methods:Random,double-blind clinical trial;We selected 30 patients with HBsAg and HBV DNA positive for positive group and 30 health volunteers with HBsAg and HBV DNA negative for negative group.We also selected three of HBV DNA positive and negative samples for repeat test.Results:The 30 samples of positive group were detected HBV DNA.The 30 samples of negative group were not detected HBV DNA.However,in positive group,the HBV DNA levels were different.The related index of ABI 7000 with ABI 7300,ABI 7500 and ABI 7300 with ABI 7500 was 0.89,0.89 and 0.98,respectively.The HBV DNA level was highest detected with ABI 7300 instrument,and then with ABI 7000 instrument.The lowest level was detected with ABI 7500 instrument.There was significance among these instruments(p
