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.

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

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 evaluate the effect of repeated intranasal insulin on postoperative delirium (POD) in elderly patients undergoing general anesthesia.Methods:Seventy elderly patients, aged ≥65 yr, with body mass index ≤28 kg/m 2, of American Society of Anesthesiologists physical statusⅠ-Ⅲ, undergoing elective radical gastrectomy for gastric cancer under general anesthesia, were divided into 2 groups ( n=35 each) according to the random number table method: control group (group C) and insulin group (group I). In group C, normal saline 0.5 ml was administered intranasally twice a day from 2 days before surgery until the day of surgery.In group I, insulin 20 U (0.5 ml) was administered intranasally twice a day from 2 days before surgery until the day of surgery.The regional tissue oxygen saturation (rSO 2) was measured after entering the operating room (T 0), at intubation (T 1), at 1, 2 and 3 h after the start of operation (T 2-4), at the end of surgery (T 5) and at extubation (T 6). The insulin allergic reactions, nasal irritation and hypoglycemic reactions were recorded after intranasal administration of insulin or normal saline within 2 days before operation.The blood glucose concentrations were measured at T 0, T 3 and T 5.The occurrence of POD within 3 days after operation was recorded. Results:Compared with group C, the incidence of POD was significantly decreased within 3 days after operation, and the rSO 2 was increased at T 1-6 in group I ( P<0.05). The rSO 2 was significantly higher at T 1-6 than at T 0 in two groups ( P<0.05). There were no significant changes in blood glucose concentrations at T 0, T 3 and T 5 between the two groups ( P>0.05). No insulin allergic reactions, nasal irritation and hypoglycemic reactions occurred in two groups ( P>0.05). Conclusion:Repeated intranasal administration of insulin can increase the rSO 2 during operation and decrease the occurrence of POD in elderly patients undergoing radical gastrectomy for gastric cancer.
