AIM: To evaluate the clinical outcomes of management in younger patients with primary chronic angle-closure glaucoma (PCACG).METHODS: Thirty-eight patients (50 eyes) aged 40 or younger with confirmed diagnosis of PCACG in advanced or late stage who received surgical treatment in Zhongshan Ophthalmic Center from January 2000 to December 2005were retrospectively investigated. All patients underwent trabeculectomy. The mean follow-up was 23.6±7.5 months.Full ophthalmic examinations were performed. The clinical outcomes including clinical presentations, surgical results and complications were evaluated.RESULTS: The mean age of patients was 33.5±6.1 years old. There was a female preponderance (60.5%). The mean axial length was 22.4±3.5mm with 18.0% short axis of eyeball and 14% nanophthalmos. There was 60.0% fiat anterior chamber depth (＜1.9mm). Ultrasonic Biomicroscopy identified that plateau iris was the most common underlying etiology (80.6%). There was a statistically significant difference in intraocular pressure (IOP) reduction postoperativelyvs preoperatively (P＜0.001). Four eyes failed to control IOP and received second filtration surgery. The main postoperative complications included shallow anterior chamber (20.0%) and malignant glaucoma (12.0%).CONCLUSION: The younger PCACG patients in advanced or late stage can be effectively managed by trabeculectomy.They have more frequency of postoperative sustained shallow anterior chamber and malignant glaucoma. Careful ophthalmic examinations, delicate surgical procedures and well-managed technique of complications were suggested on younger PCACG patients.

Objective To investigate the improvement of postpartum pelvic floor by rehabilitation training assessed with three-dimensional transperineal ultrasound . Methods One hundred cases of healthy postpartum women were randomly divided into two groups :control group and training group .The control group received the customary education ,and the training group received pelvic floor rehabilitation training . At 6 and 12 weeks postpartum ,levator hiatus area ,thickness of the levator ani muscle ,bladder neck mobility ,and bladder posterior horn were measured with three-dimensional transperineal ultrasound in all the subjects . Meanwhile ,the muscle strength situations were tested . Results At 12 weeks postpartum ,the anal levator hiatal area ,bladder neck mobility and bladder posterior horn in the training group were lower than those of the control group[ ( 21 .6 ± 3 .2) cm 2 vs ( 25 .6 ± 2 .4 ) cm 2 ,( 27 .9 ± 5 .3) mm vs ( 31 .5 ± 5 .9) mm ,( 126 .3 ± 21 .2)° vs (135 .3 ± 11 .6)°] ( P < 0 .05) . Compared with control group ,the thickness of the levator ani muscle increased in training group [ ( 13 .6 ± 2 .3) mm vs ( 15 .3 ± 2 .5) mm ] ( P < 0 .05) . The incidence of stress urinary incontinence in the training group ( 5% ) was significantly lower than the control group ( 12 .5% ) at 12 weeks postpartum ( χ2 = 5 .487 , P = 0 .025) . The muscle strength had no significant difference at 6 weeks postpartum . At 12 weeks postpartum ,the pass rate of class Ⅰ muscle fiber was 78 .5% ,and that of class Ⅱ muscle fiber was 83 .3% in the training group ;the pass rate of class Ⅰ muscle fiber was 28 .5% ,and class Ⅱ muscle fiber was 37 .3% in the control group , the improvement was significant at 12 weeks postpartum . Conclusions The result of the transperineal real-time ultrasonographic evaluation of post-natal pelvic floor rehabilitation training has high consistency with the measurement of muscle strength . The ultrasound examination is simple and accurate ,and has highly applicable value in evaluating the effect of post-pelvic rehabilitation training .

OBJECTIVEConditioned taste preference (CTP) is a taste learning reflex by which an animal learns to prefer a substance which tastes not well and has been studied with much interest in recent years. However, the neural substrates of CTP are less known. This study aimed to determine the possible neural path- ways of CTP and whether serum leptin level and the leptin receptor (OB-Rb) in the hind brain are involved following CTP formation.

METHODSWe established CTP of quinine in rats with a 2-bottle preference test. The serum leptin concentrations were detected, the expression of c-fos in the rat brain was tested to determine the nuclei in relation with establishment of CTR Finally, the OB-Rb mRNA expression was examined by RT-qPCR assay in parabrachial nucleus (PBN) and the nucleus of the solitary tract (NST) of the hind brain.

RESULTSCompared with control group, the level of serum leptin was higher in the CTP group (4.58 ± 0.52 vs 1.67 ± 0.25 µg/L, P < 0.01); increased c-fos positive cells were found in the anterior hypothalamus (AH, 221.75 ± 4.96 vs. 178.50 ± 6.63 cells/mm², P < 0.05), the basal lateral amygdala (BLA, 70.75 ± 6.17 vs 56.50 ± 3.62 cells/ mm², P < 0.05) and the nucleus of the solitary tract (NST, 41.25 ± 1.32 vs 32.50 ± 1.02 cells/mm², P < 0.05). But in ventromedial nucleus of the hypothalamus (VMH, 20.75 ± 2.73 vs 38.5 ± 1.54 per 1 mm², P < 005), PBN (21.50 ± 2.24 vs 36.25 ± 1.49 cells/mm², P < 0.05) and the central nucleus of the amygdala (CeA, 22.25 ± 1.53 vs 35.50 ± 2.11 cells/mm², P < 0.05), the number of c-fos positive cells was decreased in the CTP group. In addition, we found OB-Rb mRNA expression in PBN of CTP group rats was higher than that of control group (0.95 ± 0.055 vs 0.57 ± 0.034, P < 0.05), while there was no significant difference of OB-Rb mRNA expression in NST between the two groups.

CONCLUSIONNuclei AH, BLA, NST, VMH, PBN and CeA participate in the formation of CTP. Leptin and its receptor in PBN may be involved in the formation and maintenance of CTP.

OBJECTIVETo make a comparison between the single and combined use of Monkshood Root and Peony Root to observe the anti-inflammation effect in the experimental animals.

METHODThe experimental inflammatory models were adopted, i.e. adjuvant-induced polyarthritis carrageenan-induced or formaldehyde-induced rat paw edema, and cotton pellet-induced granuloma formation in rats xylene-induced mouse ear edema, exudation of abdominal blood capillaries of mice, etc.

RESULTThe anti-inflammafion effect of Monkshood Root was weaker than that of Peony Root or Peony Root combined with Monkshood Root. It was found that anti-inflammation effect with the drug-cooperation was enhanced more significantly in the formaldehyde-induced or adjuvant-induceed arthritis models than in the carrageenan-induced rat paw edema and other inflammatory models either in the large dosage of 1:1 proportion or in the small dosage of 1:2 proportion.

CONCLUSIONThe drug-cooperation has a good selective and synergic effect on anti-inflammation.

Objective:To investigate the correlation between the location and volume of cerebral microbleeds (CMBs) and lacunar infarction (LI) in patients with cerebral small vessel disease (CSVD).Methods:Participants from the CSVD cohort in the Department of Neurology, Nanjing Drum Tower Hospital, the Affiliated Hospital of Medical School of Nanjing University from February 2017 to March 2019 were enrolled retrospectively. All participants underwent magnetic resonance imaging scans, standardized clinical assessment and diagnosis. AccuBrain, an automatic brain segmentation and quantification software developed by the Chinese University of Hong Kong, was used to quantitatively analyze the volume of CMBs and white matter hyperintensities (WMHs). Ordered multi-class logistic regression analysis was used to determine the independent influencing factors of LI, and then multiple linear regression analysis was used to investigate the correlation between the volume of deep or infratentorial CMBs (DI-CMBs) and the number of LI. Results:A total of 317 patients with CSVD were included in the analysis, including 214 (67.5%) in the non-LI group, 43 (13.6%) in the single LI group, and 60 (18.9%) in the multiple LI group. The comparison of the three groups showed that older age, male, smoking, drinking, history of previous stroke or transient ischemic attack (TIA), lower levels of high-density lipoprotein cholesterol, larger CMBs and WMHs volume, higher enlarged perivascular spaces (EPVS) grade might be the risk factors for LI. Ordinal multivariable logistic regression analysis showed that male (odds ratio [ OR] 2.058, 95% confidence interval [ CI] 1.084-3.909; P=0.027), previous stroke or TIA history ( OR 1.962, 95% CI 1.089-3.535; P=0.025), larger WMH volume ( OR 8.716, 95% CI 4.034-18.832; P<0.001), higher EPVS grade ( OR 1.915, 95% CI 1.292-2.839; P=0.001), larger DI-CMB volume ( OR 1.022, 95% CI 1.006-1.038; P=0.008) or more DI-CMB number ( OR 1.187, 95% CI 1.005-1.403; P=0.044) were the independent related factors of LI. Multiple linear regression analysis showed that there was a significant correlation between the volume of DI-CMB and the number of LI ( r=0.330, P<0.001). Conclusion:In patients with CSVD, there is a significant correlation between DI-CMBs and LI.
