Objective To evaluate imaging diagnosis, differential diagnosis, surgery and interventional therapy of hepatic angiomyolipoma associated with tuberous sclerosis.Methods Clinical features, imaging appearances and interventional therapy for 2 cases of HAML in TS were retrospectrively analyzed. Results The features of HAML in TS are as following:(1) Two cases were female with no history of hepatitis and hepatocirrhosis, liver function test and alpha feto protein were normal. (2) the tumor was shown as a multiple hyperechoic mass with sharp margin on ultrasonography; well defined, fat density and intensity mass on computerized tomography (CT); hypervascular mass with early drainage of hepatic vein and tumor staining on angiography. (3) One case underwent interventional therapy. After 42 month follow up, the tumor was found to be diminished in size. Another case was under monitored with only the enucleating of left renal mass. The hepatic tumor showed no change after 10 months.Conclusions The imaging appearances of HAML in TS are relatively characteristic. Superselective arterial embolization is an effective treatment for HAML in TS.

Objective To develop a special ambulance for airfield rescue of pilots in danger or offering medical care for pilots in flight.Of course the ambulance can also be used to rescue the wounded daily or in the war.Methods The ambulance owned a cross-country motorcar chassis and bearing carriage.A luffing extension-jib was installed on top of the carriage with a telescopic nacelle.The medical carriage owned a generator,air-conditioner,launder & antisepsis facilities,telescopic medical table,Air Force medical facilities for first aid and so on.It could simultaneously treat 2 injured pilots in lying position.Oxygen outputs were equipped to sustain Persons in carriage.Result The maximal speed of the ambulance was 95 km/h.The time of simulated rescue was about 3 minutes in the maxium height.Conclusion Without new staff established,the ambulance can adapt to any road and is suitable to war field.It can arrive at the location of flight accident quickly and rescue the pilot rapidly.It meets the needs of medical support in flight,war-time medical care in airport and mobile accompanying support.

Background: It is unknown if medication-overuse headache, clinically similar to chronic tension-type headache, has pre-attentive problems which may be related to pain or substance abuse. Methods: Auditory frequency deviance elicited mismatch negativity was recorded from 22 patients with chronic tension-type headache, 26 with medication-overuse headache from underlying chronic tension-type headache and 41 healthy volunteers as controls. Their depression and anxiety scores were noted. Results: There were no signifi cant differences in the N1 latency or amplitude to both standard and deviant stimuli for the different groups. However, the latency and amplitude of mismatch negativity were signifi cantly shortened and reduced at Fz, Cz, and Pz in medication-overuse headache as compared to chronic tension-type headache and normal subjects. Anxiety levels were elevated in chronic tensiontype headache and medication-overuse headache subjects compared to healthy controls but were not correlated with mismatch negativity latency or amplitude in a given group. Conclusions: In medication-overuse headache subjects, the shortened mismatch negativity latency indicates quick involuntary attention switching to auditory change, while its reduced amplitude indicates poor accuracy in discriminating early stimuli, which may be related to medication overuse rather than to the head pain experienced.

OBJECTIVETo observe the clinical effect of Guilu Erxian Glue Cataplasm (GEGC) on carcinoma of the large intestine patients with myelosuppression after chemotherapy, and further to confirm its efficiency and safety.

METHODSTotally 60 patients with carcinoma of the large intestine were randomly assigned to two groups. Meanwhile, they all accepted FOLFIRI chemotherapy. Patients in the treatment group were additionally applied at Shenque (RN8), exchanging once per every other day, for 14 successive days. Patients in the control group took placebos with the same dose and dosage as the treatment group. The blood cell counts (WBC, NE, and PLT) were detected before chemotherapy, at day 7, 10, and 14. The TCM symptoms integrals, Karnofsky performance score (KPS), liver and kidney functions were observed before chemotherapy, at day 7 and day 14. Adverse skin reactions were observed each day. And the usage of hematopoietic growth factors was recorded.

RESULTS(1) The KPS score at day 7 was more stable in the treatment group than in the control group; the WBC and NE counts in the peripheral blood at day 14 were higher in the treatment group than in the control group; and TCM symptoms integrals at day 14 was lower in the treatment group than in the control group, all with statistical difference (P < 0.05). (2) Compared with the control group, the PLT count was higher in the treatment group than in the control group, the usage of rhG-CSF and antibiotics was less in the treatment group than in the control group, all with no statistical difference (P > 0.05). (3) No obvious adverse reactions such as liver injury, renal injury, or skin allergy were observed.

CONCLUSIONSAdjuvant treatment of GEGC could improve carcinoma of the large intestine patients with myelosuppression to some extent. No relevant adverse reactions were found.

OBJECTIVETo develop a method for the preparative separation of gentiopicrin from Radix Gentianae by high-speed counter-current chromatography (HSCCC).

METHODThe crude alcohol extracts were eluted on a macroporous resin column and then purified by high speed counter-current chromatography (HSCCC). A two-phase solvent system composed of ethyl acetate: n-butanol: water (2 : 1 : 3) was used, and the lower phase was used as the mobile phase at a flow rate of 1.5 mL x min(-1), while the apparatus rotated at 800 r x min(-1) and the eluate was detected at 254 nm.

RESULT136 mg gentiopicrin with purity of 99.6% determined by HPLC were obtained from 300 mg crude extraction only in one-step separation and less than 200 minutes.

CONCLUSIONThe established method is simple, high efficiency and suitable for large-scale separation of gentiopicrin.

ObjectiveTo explore the effects of ziprasidone and risperidone on cognitive inhibition function through visual pathway of patients with paranoid schizophrenia.MethodsIn the open-label,flexible-dosage trial,124 patients with paranoid schizophrenia were randomly divided into ziprasidone group (120-160 mg/d)and risperidone group(4-8 mg/d) for treatment of 8 weeks.They were assessed with computerized Color Word Test (CWT) and Continuous Performance Test(CPT) through visual pathway for cognitive inhibition function,Positive and Negative Syndrome Scale for efficacy on baseline and 8th weekend.ResultsAfter treatment with ziprasidone,the error number (3.12 ± 5.23 ),the time per correct answer( ( 1.92 ± 1.38 ) s) of CWT,as well as the doubledigit mistaken number (2.31 ± 3.76)and the three-figure mistaken number( 3.15 ±2.80) of CPT reduced more than those before medication ( (4.60 ± 6.80),( 2.74 ± 1.52 ) s,(3.85 ± 3.62 ),(4.42 ± 3.53 ) ) (P ＜ 0.05 ).In risperidone.group,the double-digit mistake number of CPT(3.39 ± 3.59) after pharmacotherapy reduced more than that before pharmacotherapy(4.23 ± 3.88) (P＜ 0.05).After treatment the time per correct answer of CWT and the mistaken numbers of CPT in ziprasidone group were less than those in risperidone group(P＜ 0.05 ),meanwhile,the scores of PANSS in two groups were significantly lower than those before treatment (P ＜ 0.01 ).ConclusionIt is effective for ziprasidone and risperidone to improve the function of cognitive inhibition on patients with paranoid schizophrenia,but there is more dramatic for ziprasidone in short-term treatment.

The trace chemical components in functional Monascus rice were studied to explore the potential bioactive substances. MCI column, Sephadex LH-20 gel, and preparative liquid chromatography were used to purified the ethyl acetate extract from functional Monascus rice. Two novel pyridine Monascus pigments were isolated and identified, named monascopyridine G (1) and monascopyridine H (2), respectively based on extensive mass spectrometry (MS), infrared radiation (IR), and nuclear magnetic resonance (NMR) analysis. The molecular docking experiments between compounds 1 and 2 and peroxisome proliferators-activated receptor-gamma (PPARγ) showed that they exhibited obvious binding force with the receptor protein. Besides, the biosynthetic pathways of the two compounds were proposed, which provide a valuable reference for the selective production of these potential bioactive substances.
