Objective:To give the test in cases of changing the conditions of measurement and reference value, compare the test results, and detect the capacity of QuickCheck, so as to offer reference for the daily morning check of accelerator and the evaluation of test results. Methods:Change the output dose, field size, SSD, angle of collimator and gantry angle of the accelerator, and then evaluate QuickCheck’s capacity of monitoring accelerator accordingly. Compare the field parameters measured by QuickCheck with the data from the 3D water tank. Results:When the output dose was 1 cGy higher than the reference value or 6 cGy lower than it, the field size expanded or contracted more than 2 cm simutaneouly, SSD was 2 cm higher or 1 cm lower than reference value, the collimator rotated more than 2 °, the gantry angle rotated more than 6 °, and then the test results of QuickCheck surpassed threshold. Comparing the measuring results of QuickCheck with 3D water tank, the difference between the flatness of the two was 3.84%, symmetry (G/T) 0.67%, symmetry (L/R) 0.47%and dose rate 1.2 MU/min. Conclusion:QuickCheck is rather accurate in testing the output dose, field size, angle of collimator, flatness, symmetry and dose rate, so it could meet the requirement of accelerator’s daily QA. However, its capability is relatively poor on examining SSD and the deviation of gantry angle.

Objective To investigate the effect of Shuanghuanglian injection parafornix-injecting in treating uterine tube obstruct (UTO) and explore its mechanism. Methods Clinic study included 386 uterine tubes of 200 patients, which were randomly divided into treatment group (50 cases, treated with Shuanghuanglian injection parafornix-injecting) and three control groups - group one (50 cases, treated with Lincocin vial parafornix-injecting), group two (50 cases, treated with hydrotubation) and group three (50 cases, treated with transvaginal catheter dilation). The changes of UTO condition and blood rheology, IL-2, IgA, IgG and IgM were observed before and after treatment. Results The total effective rate of Shuanghuanglian injection in treating UTO was 97.76%. It was characterized by regulating the blood stasis and hyperviscosity, improving the immune function of human body. Conclusions Shuanghuanglian injection parafornix-injecting has obvious therapeutic effect on UTO. The effect may be related with rectifying the body pyrotoxin and blood stasis, improving pelvic blood circulation and immune function.

1. Microsurgical relationships of the arteries at the base of the brain and the trigeminal nerve were studied bilaterally on 30 brains. Twenty seven trigeminal nerves made contact with the arteries 33 times which represents 55 percent of the cases. Six of 27 trigeminal nerves had double contact.2. Of 33 arteries in contact with 27 nerves, seventeen involved the superior cerebellar arteries (SCA) (28.33?5.82%), seven the anterior inferior cerebellar arteries (AICA) (11.67?4.15%) and nine the middle inferior cerebellar arteries (MICA) (15.0?4.61%).3. The outer diameter of the superior cerebellar artery is the largest averaging 1.41?0.20 mm; the anterior inferior cerebellar artery comes next averaging 1.06?0.36 mm and the middle inferior cerebellar artery the smallest, averaging 0.62?0.14 mm.4. 27 trigeminal arteries arising from the upper or middle segement of the basal artery were found on the ventral surface of the trigeminal nerves in 17 brains, and 16 trigeminal branches arising from the AICA. MICA. and PICA were also found at the roots of 16 trigeminal nerves. Anastomoses were noted between the trigeminal arteries and the trigeminal branches in four cases of 16 trigeminal nerves.5. The association between the neurovascular contact and the trigeminal neuralgia are discussed. It is suggested that the neurovascular contact either from dorsal or ventral aspects may be the anatomical cause of the trigeminal neuralgia.6. The neurovascular contact of the trigeminal nerve with the SCA was usually on the dorsal or dorsalmedial aspect of the nerve, but the point of contact with AICA or MICA was mainly on the ventral aspect of the nerve. Besides, there are trigeminal arteries and trigeminal branches at the ventral surface of the nerve. All these topographic observations provide microsurgical information for neurosugeons.

Aiming at the problem of high-quality image reconstruction from projection data at sparse angular views, we proposed an improved fast iterative reconstruction algorithm based on the minimization of selective image total variation (TV). The new reconstruction scheme consists of two components. Firstly, the algebraic reconstruction technique (ART) algorithm was adopted to reconstruct image that met the identity and non-negativity of projection data, and then, secondly, the selective TV minimization was used to modify the above image. Two phases were alternated until it met the convergence criteria. In order to further speed up the convergence of the algorithm, we applied a fast convergence technology in the iterative process. Experiments on simulated Shepp-Logan phantom were carried out. The results demonstrated that the new method not only improved image reconstruction quality and protected the edge of the image characteristics, but also improved the convergence speed of the iterative reconstruction significantly.

Objective To compare the operation modes of AP-960 full automated ELISA system.Methods Two models were tested: beginning with adding specimens(model 1) and beginning with adding enzymes(model 2).The following factors were compared: the consumption of suckers,usage of time,result of test and the usual alarm during the test.Results The consumptions of suckers were 564 and 84 respectively.The needing time of the former mode was 125 minutes and that of the latter mode was 90 minutes.Conclusion The mode beginning with adding enzymes(model 2) is better for the current status of our clinical laboratory.

BACKGROUND:Cataract is not the necessary symptom for myotonic dystrophy(DM).But it may be the early and even only clinical symptom of DM.Molecular diagnosis can provide the important evidence for the diagnosis of DM.OBJECTIVE:To explore the characteristics of cataract in 26 patients with myotonic dystrophy of 3 pedigrees from Shanghai Songjiang area.DESIGN:Analysis on the Genealogy of Pedigree.SETTING:Department of Neurology,Shanghai Changhai Hospital.PARTICIPANTS:Twenty-six patients of 3 pedigrees,aged 7 to 71 years old,which were preliminarily diagnosed as DM patients or were suspicious DM patients,admitted to Department of Neurology,Shanghai Changhai Hospital between May 2001 and August 2003,were recruited in this study.Among the involved patients,13 corresponded to the clinical diagnosis standard from Practical Neurology,and the other 13 patients have adverse symptoms and (or) body signs of partial or mild DM,suspecting with DM patients.METHODS:①Peripheral blood of 1 mL was taken and genome DNA was extracted.By using a thermocycler,a polymerase chain reaction (PCR) was carried out to examine the CTG repeats according to criteria of molecular diagnosis (CTG repeats from 80-3350).②In addition,slit-lamp examination for specific lens opacity was carried out and the association between DM and cataract was analyzed.MAIN OUTCOME MEASURES:①CTG trinucleotide repeat numbers.②Association between DM and cataract.RESULTS:Of the 26 patients,25 participated in the final analysis except 1 who suffered from sterility clinically.①25 patients were consistent with the molecular diagnostic criteria of DM (CTG repeats from 80-3 350).The remaining 1 with CTG repeats of 13 was clinically sterility and therefore belonged to the normal individual.The (CTG)n triplet repeats of 17 patients with cataract were 2380±80,while 8 patients with cataract were 2298±105(P＞0.05).②Cataract was characterized as iridescent lens opacity or blue posterior cortical lens opacity in 17 patients.Among the 17 patients,cataract in 8 patients was the only early clinical sign whose(CTG) n triplet repeats were higher than the normal ones.CONCLUSION:In the pedigrees with DM patients,characteristic cataract,as a main and even only early clinical sign,will provide important clinical evidence for the early diagnosis of DM.
