Objectives To observe the changes of magnetic resonance imaging(MRI) during the course of treatment in hepatolen-ticular degeneration (HLD) and to evaluate its related factors.Methods Sixty - three patients with HLD received routine SE sequence MRI of brain and liver.Twenty - two patients with abnormal MRI in 42 patients and each of them had 2-4 times of serial MRI ex-aminations at interval of 1.0- 1.5 year.Results Ten patients had lesion in both brain and liver in 22 patients. Nine patients only in brain, 3 patients in liver.The major lesions disappear or decrease after rational treatments. There were only slight or no changes of MRI abnormalities in patients receiving treatments or age of patients was over 15 year old. Abnormal MRI findings shown again after stopped treatments over 2 months. In such cases, the clinical and MRI improvements were slow.The rate of clinical and MRI improvement in patients with adequate treatment were markedly higher than patients with inadequate treatment.Conclusions Liver and brain lesion will show in MRI disappear after adequate treatment;There are only slight or no change or showing again in MRI abnormalities in pa-tients with inadequate treatments compared with poor clinical improvement. MRI is beneficial to understanding therapeutic effect and prognosis of HLD.

Persicae Semen (PS), a traditional Chinese medicine, has been widely used for the syndrome of blood stasis in China since the Eastern Han Dynasty. In the present study, we developed an HPLC-UV fingerprint analysis method for the quality control of PS. The HPLC fingerprint was performed on Shimadzu Inertsil C18 column (4.6 mm x 250 mm, 5 microm) at 35 degrees C. The mobile phases were composed of acetonitrile and water using a gradient elution. The flow rate was 1.0 mL x min(-1), and the detection wavelength was set at 210 nm. The fingerprint method was validated according to the Guidelines for Traditional Chinese Medicine Injection Fingerprint, and applied to determine 41 batches representative herbs collected from Xinjiang of China. The chromatographic peaks were characterized by UPLC-Q-TOF-MS, and nine of them were identified by comparison with the literature and/or reference standards. In order to classify and assess the samples, hierarchical clustering analysis and partial least square discriminant analysis were performed based on the common chromatographic peaks, and the samples were geographically classified into two classes, with six chemical compounds as classification markers which were significantly different between the two classes (P < 0.05).

The tail suspension test (TST), forced swimming test (FST) and chronic unpredictable mild stress (CUMS) model were used to evaluate the anti-depressant effect of supercritical CO2 extract from Compound Chaigui Fang (FFCGF). A nuclear magnetic resonance (NMR)-based metabonomics combined with multivariate statistical analysis was performed to explore the mechanism of FFCGF. Rats were conducted by CUMS procedure for 28 days and drugs were administrated at the same time. The body weight, sucrose preference, crossings and rearings in open-field tests were evaluated and the urine was collected simultaneously. The metabonomic profiles of rats' urine were analyzed by NMR and potential biomarkers were searched by multivariate statistical analysis. The results showed that administration of FFCGF significantly decreasing the immobility time in FST and TST and improving rats' body weight, sucrose preference, crossings and rearings in CUMS, which were indication that the anti-depressant effect of FFCGF was abvious. Significant differences in the metabolic profile of the CUMS treated group and the control group were observed, which were consistent with the results of behavioral tests. Decreased levels of acetic acid, succinic acid, 2-oxidation glutaric acid and citric acid and increased glycine and pyruvic acid in urine were significantly affected by the CUMS procedure and the 6 biomarkers were reversed evidently after administration of FFCGF. These changes were suggestion that the anti-depressant mechanism of FFCGF was associated with energy metabolism, lipid metabolism and amino acid metabolism.

This study examined the effect of cholic acid (CA) on cultured cardiac myocytes (CMs) from neonatal rats with an attempt to explore the possible mechanism of sudden fetal death in intrahepatic cholestasis of pregnancy (ICP). Inverted microscopy was performed to detect the impact of CA on the beating rates of rat CMs. MTT method was used to study the effect of CA on the viability of CMs. CMs cultured in vitro were incubated with 10 μmol/L Ca(2+)-sensitive fluorescence indicator fluo-3/AM. The fluorescence signals of free calcium induced by CA were measured under a laser scanning confocal microscope. The results showed that CA decreased the beating rates of the CMs in a dose-dependent manner. CA could suppress the activities of CMs in a time- and dose-dependent manner. CA increased the concentration of intracellular free calcium in a dose-dependent manner. Our study suggested that CA could inhibit the activity of CMs by causing calcium overload, thereby leading to the sudden fetal death in ICP.

Objective To observe the effect of intensive scapular control training on pain, upper limb motor function and activities of daily living (ADL) in patients with post-stroke shoulder pain. Methods 58 patients with hemiplegia after stroke were randomly assigned into routine exercise group (group A, n=27) and intensive scapular control training group (group B, n=31). They were assessed with visual analogue scale for pain, simplified Fugl-Meyer Assessment and modified Bathel Index before and 8 weeks after treatment. Results All the assessment appeared better in group B than in group A after treatment (P<0.05). Conclusion Intensive scapular control training can promote the recovery of motor function and ADL, relieve the pain in patients with post-stroke shoulder pain.

Objective To explore the influence of pelvis obliquity in lateral position to acetabular component orientation during total hip arthroplasty (THA),and the method to correct.Methods Fifty patients (62 hips) were performed THA with posterolateral incision in lateral position by the same team.The patients were randomized and divided into experimental group (EX,with 25 cases,34 hips) and control group (CON,with 25 cases,28 hips).In EX group,the acetabular components were placed by means of the gradienter and plumb correcting technique during THA.While in CON group,the acetabular components were placed by traditional method during THA.The acetabular abduction angles were measured postoperatively,and compared between the two groups.Results The average obliquity of pelvis was-1.647°±4.512°in EX group when putting the patient in lateral position before correcting.Through the application of gradienter and plumb,the average abduction angle of acetabular component was 42.685°±3.355° postoperatively,with the difference of 1.962°±1.515° compared with the preoperative angles.And in CON group,the average abduction angle of acetabular component was 44.534°±4.844° postoperatively,with the difference of 4.244°±3.042°.The difference of abduction angle in CON group was much higher than that in EX group (P＜0.05).Conclusion The pelvic obliquity when putting the patient under lateral position will affect the surgeons'judgments of placing acetabular component during THA,furthermore,lead to inconsistency among the abduction angles obtained preoperatively,intraoperatively and postoperatively.By applying the correcting method with gradienter and plumb,the discrepancy can reduce obviously between the abduction angle measured postoperatively and that of measured during operation comparing with traditional method.
