Objective To study the clinical characteristics of lymphatic malformation(LM).Methods Clinical data of 14 cases with LM were analysed and literatures were reviewed.Results ①Among the 14 cases,6 were diagnosed as primary intestinal lymphangiectasia(PIL)and 8 as primary lymphedema(PL);②The major manifestations of PIL are symmetry edema,diarrhea,lymphocytopenia,hypoproteinemia and chylopericardium.The manifestations of PL included asymmetry edema of lower limbs and respiratory symptoms;③Directed oil-contrast lymphography and isotope techniques demonstrated absence of contrast in some lymphatic segments and blockage of chylous reflux;④White opaque spots were found on the duodenal and intestinal mucosa in the endoscopy of 6 cases of PIL indicating lacteal vessels dilation.Pathological examinations revealed intestinal lymphangiectasia;⑤Six cases of 14 patients were treated with surgical therapy and 8 cases were treated with conservative therapy including medium chain triglyceride(MCT).Conclusion LM should be diagnosed on the bases of typical clinical manifestations specific laboratory findings and by lymphography and pathology.Combination of surgical therapy and conservative therapy is recommended to treat the LM patients.

Objective To investigate the CT features of pulmonary sarcoidosis.Methods Ninety patients with histologically proved pulmonary sarcoidosis were retrospectively studied by using CT scans and clinical recording.Results The main CT findings of pulmonary sarcoidosis were nodules which were seen in 69 cases(76.7%),and the nodules mostly distributed around the bronchovascular bundle(n=37, 41.1%).Other abnormalities included consolidation(n=31,34.4%),ground-grass(n=39,43.3 %), thickening of bronchovascular bundle(n=30,33.3%),interlobular septal lines(n=58,64.4%), fibrosis(n=17,18.9%)including bronchial distortion(n=8,8.9%),linear shadow(n=5,5.6%), and honeycombing shadow(n=4,4.4%),air-trapping(n=3,5.3%),bronchial straitness(n=8, 8.9%),pleural thickening(n=42,46.7%),and hilar and mediastinal adenopathy(n=76,84.4%). Two or more abnormal findings co-existed in 83 cases.The pulmonary lesions co-existed with hilar and mediastinal adenopathy in 76 cases.The nodules(n=25),consolidation(n=9),ground-grass(n=11), thickening of bronehovascular bundle(n=10)were improved after therapy.Ten cases of the interlobular septal(10/22),0 of bronchial distortion(0/4),1 case of diffuse linear(1/3),and 0 case of honeycombing(0/2)were improved.Conclusion CT manifestations of pulmonary sarcoidosis are varied, but has some specific radiographic features.A correct diagnosis can be made.combined with hilar and mediastinal adenopathy.

Animal models with kidney disease are generally divided into two types. One belongs to the models which imitate human kidney disease by the artificial operations, such as anti-glomerular basement membrane antibody nephritis, Heymann nephritis, anti-Thyl. 1 antibody nephritis, BSA nephritis and puromycin nephropathy. The other one pertains to the models which make themselves kidney disease, and appear the pathological characteristics naturally as like as human, such as HIGA mice with IgA nephropathy and NZB/WF1 and MRL/1pr mice with lupus nephritis. In addition,the transgenic animal models with kidney disease can also be established by the modern molecular biologic techniques including gene knockout and siRNA transfection. As for the studies related with kidney disease in pharmacodynamics and pharmacology of Chinese herbal medicine (CHM), it is important to understand deeply the features of each animal model with kidney disease, and select accurately the proper models according to the different experimental objectives, and then, build the special models provided with the combination of disease with syndrome in traditional Chinese medicine (TCM). Therefore,it is the developmental direction for the further study to establish animal models with kidney disease, which should possess the characteristics of syndrome in TCM.

Objective To evaluate the molluscicidal effect of niclosamide ethanolamine salt clustable powder (DP). Methods A comparative molluscicidal experiment was carried out by spraying method with niclosamide ethanolamine salt 4% DP. The experiments were respectively done in the labatory and field. The spraying with niclosamide ethanolamine salt 50% wettable power (WP) was used as the control. Results The molluscicidal effects of niclosamide ethanolamine salt 4% DP and 50% WP were similar in the laboratory. In the field, the effect of niclosamide ethanolamine salt 4% DP was lower than that of 50% WP in 3 d. However, the molluscicidal effects of the two formulations had not significant difference after 7 d. Conclusion The molluscicidal effects of niclosamide ethanolamine salt 4% DP and 50% WP were almost the same. DP is suitable for some areas where water are lack, or the water level are difficult to control.

OBJECTIVETo evaluate the effect of capsule endoscopic examination in the diagnosis of vascular malformation of small intestine and discuss the operative method of this disease.

METHODSThe clinical data of 11 cases of vascular malformation of small intestine by the capsule endoscopic diagnosis were analyzed retrospectively.

RESULTSAll of the 11 cases received operation with the assistance of intra-operative endoscopic examination, and 10 cases were confirmed to suffer from vascular malformation of small intestine postoperatively. The methods of operation included dot-resection, wedge-shaped resection and segmental resection.

CONCLUSIONSThe capsule endoscopic examination is optimal for the diagnosis of vascular malformation of small intestine. Dot-resection, wedge-shaped resection and segmental resection with the assistance of intra-operative endoscopic examination for the surgical intervention of this disease are recommendable.

Objective To observe the clinical efficacy of Tiao Shen Jie Jing needling (regulating the mind and release spasm) in treating post-stroke upper-limb spastic palsy. Method Ninety patients with post-stroke upper-limb spastic palsy were randomized into an observation group and a control group, 45 cases each. The observation group was intervened by Tiao Shen Jie Jing needling, while the control group was given ordinary acupuncture. The Modified Ashworth Scale (MAS), short-form Fugl-Meyer Assessment (SFMA) and Barthel Index (BI) were evaluated and recorded prior to the treatment, after 2-week and 4-week treatment and 3 months later after the intervention; the serumγ-aminobutyric acid (GABA) was detected before and after the treatment. Result The total effective rate was 83.3% in the observation group versus 61.0% in the control group, and the efficacy of the observation group was superior to that of the control group (P<0.05). The scores of each scale showed improvements after the treatment in both groups (P<0.05), and the improvements in the observation group were more significant (P < 0.05). The follow-up showed continuing improvements in the scales in the observation group, which were superior to those in the control group (P<0.05); after the treatment, the content of GABA in the observation group was significantly higher than that in the control group (P<0.05). Conclusion Tiao Shen Jie Jing needling can effectively ameliorate the upper-limb spasm,as well as the motor function of the upper extremities, improve the activities of daily living and maintain a long-term efficacy, better than ordinary acupuncture. The action mechanism is related to the regulation of GABA content in serum.

OBJECTIVEAfter performed symptom-limited maximum cardiopulmonary exercise testing (CPET) before and after acute alkalized blood, we repeated CPET with pure oxygen.

METHODSFive volunteers, 3hr after alkalizing blood room air CPET, re-performed CPET inhaling from Douglas bag connected with pure oxygen tank. We compared with those of room air CPETs before and after alkalized blood.

RESULTSAfter alkalized blood oxygen CPET had a similar response pattern as those of CPETs before and after blood alkalization. During the CPET, all breath frequency, minute ventilation and tidal volume at each stage were similar to those of CPETs before and after alkalized blood (P > 0.05),except there was a lower peak tidal volume than those of both CPETs and a slightly higher resting minute ventilation only than CPET after alkalized blood (P > 0.05). After alkalized blood, oxygen CPET, all PaO2 and SaO2 and most Hb were lower than those of both CPETs (P < 0.05). The pHa and [HCO3-]a were higher than those of CPET before alkalized blood (P < 0.05); but were not CPET after alkalized blood (P > 0.05). PaCO2 was similar to that of CPET before alkalized blood (P > 0.05), but was lower than that of CPET after alkalized blood at resting and warm-up (P < 0.05); then was similar to both CPETs at anaerobic threshold (P > 0.05); but was higher at peak exercise higher than those of both CPETs (P < 0.01). Oxygen increased 2,3 volunteers' workload and time at AT and peak exercises.

CONCLUSIONRespiratory response pattern to oxygen CPET after alkalized blood is similar to those of both CPETs before and after alkalized blood. The CPET response is dominantly depended upon metabolic rate, but not levels of pHa, PaCO2 and PaO2.

OBJECTIVETo demonstrate the effects and mechanisms of Huangkui capsule (HKC) on renal fibrosis in rats with diabetic nephropathy (DN).

METHODRats were randomly divided into 5 groups, the sham-operated group (Sham group, n = 5), the vehicle-given group (Vehicle group, n = 7), the low dose of HKC-treated group (L-HKC group, n = 7), the high dose of HKC-treated group (H-HKC group, n = 7) and the lipoic acid (LA)-treated group (LA group, n = 7). DN models were induced by intraperitoneal injection of streptozotocin (STZ,35 mg x kg(-1)) twice and unilateral nephrectomy. After models were successfully established, the rats in HKC and LA groups were daily administrated with HKC suspensions (0.75, 2 g x kg(-1)) or LA suspensions (60 mg x kg(-1)) respectively, and at the same time, the rats in Vehicle group were daily administrated with distilled water (2 mL) for 8 weeks. All rats were sacrificed at the end of week 8 to collect blood and renal tissues. UAlb, renal function, renal fibrotic morphologic characteristics, as well as oxidative stress (OS)-related markers, the protein expressions of the key signaling molecules in p38 mitogen-activated protein kinase (p38MAPK) signaling pathway, fibrogenic cytokines and inflammatory factors were examined respectively.

RESULTHKC, similar to LA, improved the general state of health, body weight, UAlb, BUN, UA and Alb in DN model rats. Of note, renal fibrosis was ameliorated in HKC groups,especially in H-HKC group which was better than that in LA group. In addition, HKC not only improved the main indexes of OS in the kidney like LA, but also down-regulated the protein expressions of phosphorylated-p38MAPK (p-p38MAPK), transforming growth factor (TGF)-β1 and tumor necrosis factor(TNF)-α in the kidney, whereas, LA only decreased the protein expression of TNF-α in the kidney in DN model rats.

CONCLUSIONHKC, similar to LA, has the actions of anti-OS in vivo. Moreover, HKC could attenuate renal fibrosis by suppressing the activation of p38MAPK signaling pathway and the protein expressions of fibrogenic cytokines and inflammatory factors in the kidney in DN model rats, which is different from LA.
