Objective To study the features of anatomical delamination of the posterior renal fascia in CT images.Methods Clinical datas and CT images of 85 patients with acute pancreatitis were collected,the anatomical delamination features of the adult posterior renal fascia were observed and recorded.Results (1) 23 cases showed anatomical delamination of the left posterior renal fascia, 9 cases showed anatomical delamination of the right posterior renal fascia, and 8 cases showed anatomical delamination of bilateral posterior renal fascia.(2) The features of anatomical delamination of the posterior renal fascia were detected in the whole posterior renal fascia or in the lateral part of the posterior renal fascia.Anatomical delamination was detected in the whole left posterior renal fascia in 6 cases, and was detected in the lateral part of the left posterior renal fascia in 17 cases.Anatomical delamination was detected in the whole right posterior renal fascia in 4 cases and in the lateral part of the right posterior renal fascia in 5 cases.Anatomical delamination of the whole part in the bilateral posterior renal fascia were detected in 4 cases and pure delamination of the lateral part in the both sides were 4 cases.Conclusion CT images can show the anatomical delamination of the posterior renal fascia which has two types.The anatomical delamination of bilateral posterior renal fascia is not always the same.

As a basic amino acid, histidine has a pK_a close to the acidity of the tumor microenvironment, thus the charge and solubility of histidine are able to vary as the pH changes. Under a neutral environment, histidine is not charged and exhibits hydrophobic properties, while it can be protonated and becomes hydrophilic when exposed to mildly acidic pH, such as tumor microenvironment. Therefore, histidine is widely used in the design of drug delivery systems to target the mildly acidic pH of tumor microenvironment. This article reviews the recent progresses of histidine-based tumor-targeting drug delivery systems, and summarizes the principles on promoting internalization and tuning drug release by taking advantage of histidine. Finally, we point out the common issues on histidine application and illustrate its future prospects.

Objective: To unveil the efficacy of Shaolin internal qigong exercise in treating capsulitis of the shoulder (CS) and explore objective outcome measures by observing the changes in the surface electromyography (sEMG) signals of shoulder muscle groups after regular practice of Shaolin internal qigong exercise in CS patients. Methods: Sixty CS patients were randomized into two groups by the random number table method, with 30 cases in each group. Patients in the qigong group practiced Shaolin internal qigong exercise on a regular basis, while patients in the electroacupuncture (EA) group received EA treatment. Before and after treatment, the sEMG signals of six muscles, i.e. biceps brachii, triceps brachii, deltoid, pectoralis major, latissimus dorsi and trapezius muscles, of the affected side were recorded at 45° abduction of the shoulder, 60° forward flexion and 90° internal rotation with the elbow flexed during maximal isometric contraction, and the integrated electromyography (iEMG) of each muscle was calculated. Results: The total effective rate was 93.3％ in the qigong group, higher than 83.3％ in the EA group (P<0.05). Intra-group comparison showed that the iEMG of biceps brachii, triceps brachii, pectoralis major and deltoid muscles in the qigong group increased significantly after intervention at 45° abduction of the shoulder, 60° forward flexion and 90° internal rotation with the elbow flexed (all P<0.05), and the iEMG of trapezius and latissimus dorsi muscles decreased (both P<0.05); in the EA group, the iEMG of biceps brachii, pectoralis major and deltoid muscles increased significantly during contraction (all P<0.05), while the iEMG of triceps brachii, trapezius and latissimus dorsi muscles had no significant changes (all P>0.05). After intervention, there were significant differences in the iEMG of most of muscles between the two groups (all P<0.05), except for the iEMG of deltoid muscle at 45° of abduction of the shoulder joint during isometric contraction (P>0.05). Conclusion: Shaolin internal qigong exercise can effectively increase the motion intensity of the biceps brachii, triceps brachii, pectoralis major and deltoid muscles and reduce the compensation of the latissimus dorsi and trapezius muscles in CS patients; compared with EA, it produces a better result in improving the coordination and stability in shoulder joint movements.

OBJECTIVETo observe the effect of Yangfei Ziyin Decoction (YZD) on symptoms, serum levels of TNF-alpha, IL-6, and aquaporin-5 (AQP-5), and pathology of Sj6gren's syndrome (SS) model mice.

METHODSTotally 60 mice were divided into 6 groups according to random digit table, i.e., the model group, the normal control group, the high, medium, low dose YZD groups (administered with YZD at 36.7, 18.4, 9.2 g/kg, 0.2 mL/10 g), the Chinese patent medicine group [CPM, administered with total glucosides of paeony at 0.6 g/kg], 10 mice in each group. All intervention was performed for six successive days in a week, with an interval of one day, a total of 50 days. Body weight, salivary secretion, food and water intake were measured at day10, 20, 30, 40, and 50, respectively. At day 50 blood was collected. Submandibular gland, thymus, and spleen were weighed. Serum levels of TNF-alpha, IL-6, and AQP-5 were detected by ELISA. Pathological changes of submandibular gland were observed. Results Compared with the normal control group, there was no change in water intake of mice in the model group, but with reduced salivary secretion (P < 0.01, P < 0.05). Thymus/spleen/submandibular gland weight and index increased in the model group (P < 0.01, P < 0.05). Compared with the model group at the same time point, salivary secretion increased in the CPM group and 3 YZD groups (P < 0.01 , P < 0.05). Compared with the model group, thymus/spleen/submandibular gland weight and index decreased in the CPM group (P < 0.01, P < 0.05). Thymus/submandibular gland weight and index decreased in the low dose YZD group (P < 0.01, P < 0.05). Thymus/submandibular gland weight and index, and spleen index decreased in high and medium dose YZD groups (P < 0.01 , P < 0.05). Levels of TNF-alpha and IL-6 decreased, but AQP-5 level increased in the CPM group (P < 0.05). AQP-5 level increased in high and medium dose YZD groups (P < 0.01 , P < 0.05). In the model group alveoli and duct of salivary gland were destroyed, alveoli and duct were irregular, epithelial cells were degenerated, necrotic, and desquamated. Mild-to-moderate lymphocytic infiltration occurred around submandibular gland. Pathological changes were alleviated in the CPM group and 3 YZD groups.

CONCLUSIONYZD could improve clinical symptoms, serum levels of TNF-alpha, IL-6, AQP-5, and pathological changes of SS model mice.

Objective To establish the linear regression equation between body height and com bined length of manubrium and mesosternum of sternum m easured by CTvolum e rendering technique (CT-VRT) in southw est H an population. Methods One hundred and sixty subjects, including 80 m ales and 80 fem ales w ere selected from southw est H an population for routine CT-VRT(reconstruction thickness 1 m m ) ex-am ination. The lengths of both manubrium and mesosternum w ere recorded, and the com bined length of manubrium and mesosternum was equal to the algebraic sum of them . The sex-specific linear regression equations between the com bined length of manubrium and mesosternum and the real body height of each subject w ere deduced. Results The sex-specific sim ple linear regression equations between the com bined length of manubrium and mesosternum (x3) and body height (y) w ere established (m ale:y=135.000+2.118x3 and fem ale:y=120.790+2.808x3).Both equations show ed statisticalsignificance (P<0.05) w ith a 100% predictive accuracy. Conclusion CT-VRTis an effective m ethod for m easurem ent of the index of sternum . The com bined length of manubrium and mesosternum from CT-VRTcan be used for body height estim ation in southw est H an population.

OBJECTIVE:To provide reference for rational drug use in the clinic. METHODS:The cases of disulfiram-like reac-tion collected from the First Affiliated Hospital of Guangzhou University of TCM from July 1st in 2012 to June 30st in 2014,were analyzed and compared retrospectively. The epidemiological characteristics,causes,clinical characteristics and treatment methods were summarized. RESULTS:Disulfiram-like reaction mainly occurred in male(86.59%),mainly in young and middle-aged men aged 21-50 years old (78.05%). It might be induced by using cephalosporin antibiotics (as cefoperazone,cefperazone/sulbactam, etc.),nitroimidazole (as metronidazole,tinidazole,etc.),drinking or contacting beverage,food or drug containing ethanol. This reaction involved the skin and its accessories system,circulatory system,digestive system,nervous system,respiratory system, etc. Its clinical manifestations mainly were skin flush,chest tightness,shortness of breath,palpitation,nausea,vomiting,dizzi-ness,headache,etc.,occasional confusion,drowsiness,xerostomia,etc. Response to the severe disulfiram-like reaction,the foun-dation treatment combined with symptomatic treatment showed a good effect with remission of symptoms in 1 to 3 hours and no deaths. CONCLUSIONS:When the drugs with mercapto-1-methyltetrazole perssad as cephalosporin antibiotics,nitro imidazoles, etc.,are used,we should avoid drinking or taking drugs or food containing ethanol,to prevent the occurrence of disulfiram-like re-action.

Clinical laboratory undergraduate program was switched from medicine to medical technology,the changes of personnel training program compel universities to adjust the curriculum system.Six domestic known as 211 universities who have laboratory and biology undergraduate programs were scrutinized and compared.Overall,the proportion of general courses covers 30％ of the credit hours in both clinical laboratory and biology programs.Ratio of these general education curriculums to professional core courses is as high as 1.90∶1 in clinical laboratory program.Also,there were very strong medical features and very weak medical technology characteristics in the basic course in clinical laboratory program.It suggested that the curriculum system nowadays cant conform to the new personnel training objective.A novel system from abroad should be adopted to optimize clinical laboratory program accord with the principles and concepts of wide caliber training model.
