Objective To evaluate the relationship between damages of visual field and retinal nerve fibre layer(RNFL)thickness in primary open angle glaucoma(POAG)with high myopia.Design Retrospective,case-controlled study.Participants POAG group with high myopia(21 eyes of 17 cases),POAG group with non-high myopia(17 eyes of 16 cases),high myopia group without POAG(25 eyes of 20 cases)and normal control group(19 eyes of 17 cases).Methods The static central visual fields were tested with Humphrey 750 automated perimetry and thickness of RNFL was measured with optical coherent tomography(OCT).Main Outcome Measures Mean deviation(MD),pattern standard deviation(PSD)and mean sensitivity at upper,lower,nasal and temporal quadrants in total deviation probability plots.Thickness of RNFL at upper,lower,nasal and temporal quadrants.Results There were more obvious general depression of sensitivity in total deviation probability plots of the early POAG with high myopia than those of POAG without high myopia,and the early visual field defects of glaucoma in pattern deviation probability plots of this group.MD of POAG with high myopia was more than those of others(P＜0.05).The differences of MD,PSD and mean sensitivity between POAG with high myopia and others were significant(P＜0.05).Mean sensitivities in each quadrant of POAG without high myopia were similar to those of high myopia(P＞0.05).The thickness of RNFL of POAG with high myopia was thinner than those of others and the thickness of RNFL of normality was thicker than that of others.The correlationship between mean sensitivity and the thickness of RNFL in each quadrant was significant(P＜0.05).Conclusion Pattern deviation probability plots is an important favor for judgement of the visual field changes in POAG with high myopia.The relationship between RNFL thickness with OCT and visual field damage may provide clinically relevant information in diagnosis of POAG with high myopia

Water soluble extract (WSE) is an important index for the quality evaluation of Astragali Radix (AR). In this study, the WSE of the wild AR from Shanxi province (SX) and the cultivated AR from Gansu Province (GS) were compared. The WSEs of two types of AR were determined according to the appendix of Chinese pharmacopoeia. Then the WSEs were subjected to NMR analysis, and the obtained data were analyzed using HCA, PCA, OPLS-DA, microarray analysis, and Spearman rank analysis. In addition, the Pearson correlation of differential metabolites were also calculated. The results showed that the WSE content of GS-AR (37.80%) was higher than that of SX-AR (32.13%). The main constituent of WSE was sucrose, and other 18 compounds, including amino acids, organic acids, were also detected. Multivariate analysis revealed that SX-AR contained more choline, succinic acid, citric acid, glutamate, taurine and aspartate, while GS samples contained more sucrose, arginine and fumaric acid. In addition, the Pearson correlations between different metabolites of the two types of AR also showed apparent differences. The results suggested that the WSE of two types of AR differs not only in the content, but also in the chemical compositions. Thus, the cultivation way is important to the quality of AR. This study supplied a new method for the comparison of extract of herbal drugs.

OBJECTIVE: To observe the effects of intermedin preconditioning on hypoxic injury in rat's cardiac myocytes and to provide the hypothetical mechanism of sudden cardiac death in the field of forensic pathology. METHODS: The H9c2 cultured rat cardiac myocytes were randomly divided into control group, hypoxia group and IMD group. The myocardial cell viability, cellular ultrastructure, intracellular calcium concentration and apoptosis rate were determined by MTT assay, transmission electron microscopy, laser scanning confocal microscope and flow cytometry, respectively. RESULTS: Compared with the control group, cell viability obviously decreased with inner ultrastructure injury in the hypoxia group (P<0.05), while cell viability significantly increased in the IMD group by reducing the hypoxia injury of cardiac myocytes (P<0.05). Compared with the control group, [Ca2+]i (fluorescence intensity) and apoptosis rate significantly increased in the hypoxia group, but decreased in the IMD group (P<0.05). CONCLUSION IMD increases the cell survival rate and decreases the cell apoptosis inhibited by intracellular calcium overload from hypoxia. This finding may reveal the mechanism of protective effects of myocardial hypoxia, and provide a scientific basis for the identification sudden cardiac death.

Objective To observe the effects of comprehensive measures of changing grain,selenium supplementation,off-site education and resettlement on prevention of children's Kashin-Beck disease in Aba state.Methods Fifty eight villages in Aba Kashin-Beck disease areas were chosen as intervention points in Aba state Sichuan province from 2007 to 2011.Based on the implementation of prevention and control measures,the villages were divided into off-site education + changing grain + selenium supplementation group and resettlement + off-site education + changing grain + selenium supplementation group,Geletuo town of Seda county,Ganzi state was selected as a control point,and right-hand anteroposterior X-ray examination(including the wrist) was carried out on children aged 6-13 from 2007 to 2011 annually.Clinical and X-ray diagnosis of Kashin-Beck disease was made in accordance with the Diagnostic Criteria of Kaschin-Beck Disease(GB 16003-1995).The effects of prevention and control measures were evaluated by comparing the child X-ray detection rate before and after the implementation of the measures.Results The average X-ray positive detectable rate of children in the intervention points was 2.07％(66/3181),2.72％ (69/2540),1.16％ (35/3017),0.56％ (19/3397) and 0.56％ (24/4273),respectively from 2007 to 2011,with a downward trend (x2trend =66.74,P ＜ 0.01).There was a downward trend in the average X-ray positive detectable rate of children in off-site education + changing grain + selenium supplementation group [1.60％(29/1809),2.63％ (39/1484),1.29％ (25/1941),0.64％ (15/2332),0.42％ (10/2379)] and resettlement + off-site education + changing grain + selenium supplementation group [2.70％ (37/1372),2.84％ (30/1056),0.93％(10/1076),0.38％ (4/1065),0.74％(14/1894)] (x2trend=30.97,35.19,all P ＜ 0.01).The average X-ray positive detectable rate of children in the intervention group was 0 from 2007 to 2010,and was 1.61％ (1/62) in 2011.The difference of X-ray positive detectable rate was not statistically significant in the control group in the 5 years from 2007 to 2011.The difference of children's X-ray positive detectable rate was not statistically significant between control group and intervention group.Conclusions The effect of taking changing grain,selenium supplementation,off-site education and resettlement comprehensive measures to prevent children's Kashin-Beck disease is not significant in those places where the state of Kaschin-Beck disease is not active.

OBJECTIVETo compare the therapeutic effects between the Hwato neuro and muscle stimulator (SXDZ-100) and the regular electronic stimulator (SDZ-II) on chronic functional constipation.

METHODSSixty-four cases of chronic functional constipation were randomly divided into a (SXDZ-100) observation group (n = 33) and SDZ-II control group (n = 31). For the SXDZ-100 group, under the considerations of patients' endurance, Zhigou(TE 6) and Tianshu (ST 25), Zusanli (ST 36) and Shangjuxu (ST 37) were punctured and then the courle of acupoints on the same side were connected with SXDZ-100 apparatus in reinforcing and reducing by twirling and rotating manipulation wave for 30 min, while in the control group SDZ-II apparatus was applied in the same way mentioned above with disperse-dense wave at frequency of 1Hz/20Hz for 30 min. By means of clinical therapeutic effect evaluation and clinical symptom score, the contrast between two groups can be made.

RESULTSAlthough the total effective rates were both 100.0%, the rate of short term effects in SXDZ-100 group (54.6%, 18/33) is significantly higher than that in SDZ-II group (29.0%, 9/31) (P < 0.05). After the treatment, the clinical symptom scores in both groups decreased significantly (both P < 0.05). And the therapeutic effective indices of the SXDZ-100 group were significantly higher than those of the SDZ- II group (P < 0.05).

CONCLUSIONThe therapeutic effect of Hwato neuro and muscle stimulator (SXDZ-100) on chronic functional constipation is superior to that of a regular electronic stimulator (SDZ-II).

ObjectiveTo explore the characteristics and rehabilitation of dysarthria patients who speak mandarin. Methods18 patients were rehabilitated with physiologic approach for 40 d. Before and after rehabilitation, maximum phonation time (MPT), frequency, tone and expiratory rate were tested with phonolaryngeal graph, while forced vital capacity (FVC), forced expiratory volume in one second (FEV1), maximum midexpiratory flow (MMF), peak expiratory flow rate (PEFR) were tested with Microspiro; Articulation and intelligibility were tested with mandarin words table and rate of sentence and paragraph. ResultsCompared with that before intervention, MPT of the patients were longer after intervention (P<0.05). The FVC was lower than normal rate before intervention and it was remarkable higher after intervention(P<0.01).Correct rate of sentence and paragraph was remarkable higher(P<0.01). ConclusionTests of Phono-laryngograph, Microspiro and correct rate of sentence are good comprehensive evaluation methods to speech and phonation of dysarthria. Physiologic approach to rehabilitation can remarkably improve patient's communication ability.

OBJECTIVETo compare curative effects of various surgical procedures of bile duct stones.

METHODSTwo thousand nine hundred and fifty-five patients with intrahepatic bile duct lithiasis who had undergone various surgical procedures were analysed with Meta-analysis. Some of these cases were reported in Chinese Medical Journals from January 1990 to March 2001 and others were from Tongji Hospital.

RESULTSThere was a significant difference between curative effects of non-hepatectomy and that of hepatectomy (chi(2) = 62.945, P < 0.01), and the outcomes of hepatectomy were much better than those of non-hepatectomy with OR(S) equalled to 0.303 (0.222 - 0.413). There was not a significant difference between curative effect of interposed jejunum and that of hepatectomy (95% CI of RR from 0.98 to 1.04). All the other operation, effects were worse than hepatectomy (upper limit of 95% CI of RR < 1).

CONCLUSIONSHepatectomy is the most ideal surgery for intrahepatic bile duct stones and operation methods should be diversified since good effect could also be obtained when other operations are performed on suitable cases.

BACKGROUNDIt was still rare for the quantitative magnetic resonance imaging (MRI) research of regional changes in hippocampus sclerosis (HS) in Chinese patients with epilepsy. This study aimed to study the hippocampal volumes (HVs) with quantitative MRI measurement in Chinese patients with epilepsy.

METHODSForty-six Chinese patients with epilepsy (intractable epilepsy (IE), n = 21; non-intractable epilepsy (NIE), n = 25) and 25 normal controls were collected between July 2007 and March 2008. All of the subjects underwent a 3T high-resolution MRI with oblique coronal thin sections oriented perpendicular to the hippocampal long axis. Hippocampal structures were assessed by visual detection, and HVs were quantitatively studied with a Picture Archiving and Communication System (PACS).

RESULTSOur study suggested that there was no significant difference in gender (P > 0.05) while the right hippocampal head volume (HHV), hippocampal body volume (HBV), and the whole hippocampal volume (HCV) were greater than the left one (P < 0.05), but no significant difference was found in bilateral hippocampal tail volume (HTV) (P > 0.05) in normal controls. That unilateral/diffuse (64%/21%) and bilateral/focal (86%/20%) hippocampal atrophy (HA) were significant in IE and NIE patients, respectively. Anterior hippocampus, especially HHV (26% in IE and 20% in NIE) and HBV (29% in IE and 12% in NIE), had more significant atrophy than the HTV (5% in IE and 0% in NIE) in patients with epilepsy.

CONCLUSIONBy assessing the volumes of the regional hippocampus with 3T MRI, we could better define the range and distribution of HS, since regional or subtle changes in HVs could be detected earlier with 3T MRI.
