Objective To observe changes of luteinizing hormone (LH), follicle-stimulating hormone (FSH) and testosterone (T) in umbilical vein blood between male and female neonates, and assess the effect of serum LH, FSH and T on fetal growth.Methods Umbilical vein blood was obtained from 130 neonates (64 females and 66 males) in the second hospital of changshu city. According to birth weight, 130 neonates were divided into 3 groups: macrosomia (n=28), intrauterine growth restriction (IUGR) (n=31) and normal neonates (n=71). The serum levels of LH, FSH and T were measured by radioimmunoassay.Results 1.The levels of LH, FSH and T in umbilical vein blood were significantly higher in male neonates than those in females (P

Objective To investigate the imaging manifestations of lung neoplasms in pre- and post- treatment with CT-guided Argon-Helium cryoablation.Methods All the lung neoplasms in 96 patients have been treated with CT-guided percutaneous Argon-Helium targeted cryoablation.All patients have pre- and post-treatment CT scanning in measurement of lesion size and CT value.The CT scanning has been rerpeated afterl,3,6,12 months of treatment.Results Among total 96 cases,there are 82 cases of lung cancer and 14 cases of metastasis with 110 lesions(89 cases with single lesion,7 cases with multiple lesions).The Ar-He cryoablation has been given 103 times in total.The size of each lesion ranged from 1.2 cm to 15.0 cm in diameter with mean value of(4.0?2.5)cm,including 12 lesions less than 2 cm,51 lesions between 2— 4 cm,24 lesions between 4—6 cm,23 lesions over 6 cm.There are 25 patients whose lesions covered by iceball with 1 cm of overloaping it's margin.There are 63 lesions with diameter less than 4 cm gained 100% ablation rate,24 lesions with 4—6 cm diameter gained 95.8% ablation rate,and 23 lesions with over 6 cm diameter gained 69.6% ablation rate.The post-treatment CT show a progressively enlarged round,low density refrigerant area which clearly demarked with non- refrigerant area.The center of each refrigerant area has negative CT value,the mean decreased CT value of lesion instantly after the treatment are about 30— 50 HU with P

Objective:To develop a novel regulable sutureless aortic arch prosthesis and to apply it in an animal experimental study.Methods:The arch skeleton of the prosthesis was made of tandem Z-shape NiTiNOL wire;the branch skeleton was made of laser-cut NiTiNOL tube;and the whole skeleton was coated with thin ePTFE film.The blood vessel was anastomosed by di- rect ligature,needing no manual suturing.The prosthesis was applied in swine aortic arch operations under the bypass condi- tion.The practicality for surgery and the feasibility of anastomosis of the prosthesis were assessed.Results:Aortic arch opera- tions were successfully performed in 6 of the 8 experimental animals.The prostheses were easy to use,and the mean bypass time was only 10 min.The blood loss of the anastomoses was less than 100 ml within 8 h postoperatively in 5 animals;one had more blood loss due to prosthesis mismatch.Conclusion:The novel regulable sutureless aortic arch prosthesis has satisfactory practicality for surgery and reliable anastomosis,making it promising in future clinical application.

Phosphodiesterase 4 (PDE4) is an important member of the phosphodiesterase enzyme family that specifically catalyzes the hydrolysis of cyclic adenosine monophosphate (cAMP), activates the downstream phosphorylation cascade pathway by altering cAMP concentration, and is strongly associated with multiple diseases. Inhibition of PDE4 is clinically investigated as a therapeutic strategy in a broad range of disease areas, including respiratory system diseases, autoimmune disorders, central nervous system diseases, and dermatological conditions. However, the incidence of adverse reactions such as nausea and vomiting is relatively high in the marketed PDE4 inhibitors, which has stalled their clinical development. In this review, we provide an overview of the clinical progression and safety issues of the marketed PDE4 inhibitors. We also review the main causes underlying PDE4-mediated adverse effects by combining the structural analysis of the PDE4 protein, the mechanism of action of PDE4 inhibitors, and the related side effect mechanism research, aiming to provide a reference for the development of safe and effective PDE4 inhibitors.

OBJECTIVETo study and compare the accuracy and sensitivity of endoscopic ultrasonography (EUS) and CT scaning in determination of preoperative stage and vascular invasion by pancreatic and ampullary cancers.

METHODSFourty-two pancreatic cancer patients and 18 ampullary cancer patients were studied. With patients prepared according to conventional endoscopy, Olympus EUM-30 scope 1 set with a side view and 360 degrees rotate and switchable scanning probe [ultrasound frequency (7.5/12 MHz)], was introduced to the descending duodenum through the esophagus. Gas within the duodenum and stomach was aspirated. Then, in order to to facilitate ultrasound transmission, 200 ml deaerated water was injected into the duodenum and 500 ml into the stomach to distend it. The structures of each part of pancreatic head and ampullary together with surrounding vessels were scanned. Then, the scope was withdrawn to the gastric antrum, body and fundus gradually, while the pancreatic body and tail were scanned.

RESULTSBetween Apr. 1996 to May 2004, a total of 42 pancreatic cancer patients and 18 ampullary cancer patients were examined by EUS. Meanwhile, all these 58 patients received preoperative CT scaning. The results of stage and vascular invasion determined by EUS in this series were as following; pancreatic cancer group (n = 42): accuracy in T2-4 stage was 100.0% (5/5), 75.0% (9/12) and 48.0% (12/25), respectively; ampullary cancer group (n = 18): T1-4 stage was 75.0% (3/4), 66.7% (2/3), 75.0% (6/8) and 33.3% (1/3), respectively; the accuracy in N stage: P-group: 80.0% in N1 (4/5), 90.0% in N0 (9/10); A-group: 50.0% in N1 (3/6), 91.0% in N0 (10/11). The sensitivity, specificity of vascular invasion, resectability and unresectablilty determined by EUS and CT as compared with surgical findings during operation was 52.9% (9/17), 93.1% (27/29), 77.1% (27/35) and 81.8% (9/11) for EUS (n = 60), respectively; and 11.8% (2/17), 92.6% (25/27), 62.5% (25/40) and 50.0% (2/4) for CT (n = 58), respectively.

CONCLUSIONEndoscopic ultrosonography being one of the best image examinations to determine the stage and vascular invasion for pancreatic and ampullary cancer paitients is able to detect small pancreatic or ampullary cancer less than 2.0 cm in diameter due to its high resolution; but can not detect the secondary multiple distal metastases such as spread into the liver, peritonium or hepatoduodenal ligament, etc. due to its ultrasound depth limitation.

Two new MAR segments (M14 and M17) were cloned from tobacco genome. Both of the sequences contained several typical consensus sequences of MARs, which were different from the original MAR sequence, such as 90%AT-box, A-box, T-box, the base unpairing regions (BUR), autonomously replicating sequences (ARS), the consensus sequence for topoisomerase II, MAR recognition sequence (MRS), origin of replication (ORI), curved DNA motifs and ATATTT et al. To investigate the effects of these two sequences on gene expression in transgenic plants, 3 plant expression vectors were constructed with uidA gene coding beta-glucuronidase (GUS) which were flanked on one side and on both sides by the MARs we obtained. These plant expression vectors with one or two MARs were transformed into tobaccos via Agrobacterium-mediated transformation method, with the plant expression vector pCAMBIA2301 without MAR and wild type tobacco as controls. GUS histochemical staining results showed that the uidA gene expressed stably in transgenic tobaccos. Quantitative detection of GUS activity showed that the MARs could increase GUS expression levels in vivo in contrast to the controls, wherever they were flanked on one side or both sides of uidA gene. The vector ligated with MARs in the same direction on both sides of uidA could increase the GUS expression level much better than both vectors which just ligated with single MARs on one side. The former one increased the average GUS activity for 3.14 folds, but 1.56 and 2.43 folds for the latter two vectors with single MARs respectively contrasting to the pCAMBIA2301 control. But the expression differences among individual transformants were still obvious. Therefore, it was concluded that the DNA sequences we obtained in this experiment were two novel MARs and could enhance gene expression in vivo. In the meanwhile, although the numbers of the MARs typical motifs in M14 were more than in M17, especially the 90% AT box which had been considered to be the highest correlative motif with binding strength in vitro, the enhancement of gene expression was lower yet, which implied no correlation between improvement of gene expression and binding strength between MARs and nuclear matrix in vitro.

OBJECTIVETo explore the clinical presentation, pathologic characteristics, diagnosis and treatment of cutaneous T-cell lymphoma of the penis.

METHODSA 49-year-old man presented with painful swelling and inflammation of the foreskin, failed to respond to antibiotic treatment and dorsal incision, and was instead complicated by Fournier gangrene. Then he underwent debridement and pathological examination.

RESULTSPathological results indicated cutaneous T-cell lymphoma of the penis. Immunohistochemistry showed CD3 and CD45 RO to be positive, but CD30, CD79a, CD20 and HMB negative. The patient was treated by interferon alpha and ultraviolet B for 2 weeks, followed by total removal of the external genitalia because of necrosis of the corpus spongiosum, which involved the scrotum and right testis on pathological examination.

CONCLUSIONCutaneous T-cell lymphoma of the penis is a rare condition and easily mis diagnosed in the early phase. Definitive diagnosis depends on pathological study.

OBJECTIVETo study the accumulated toxic action to bandicoot of aqueous extract of crude and processed Radix Aristolochice and the pharmacodynamic action of aqueous and alcoholic extract of crude and processed Radix Aristolochice.

METHODThe LD50 of acute toxicity to mice and chronic accumulated toxicity to bandicoots of crude and processed Radix Aristolochice were observated. Intestinal and myokinetic influence of normal and revulsive hyperactive gastrointestinal motility of mice induced by neostigmine were observated by giving aqueous extract and alcoholic extract of crude and processed Radix Aristolochice. Relieving pain and eliminating inflammation to mice also were observated.

RESULTThe LD50 of aqueous extract of crude and processed Radix Aristolochice were 146. 45, 846.06 g X kg(-1) (equivalently to crude drug) respectively by intragastric administration. Bandicoot' general condition, peripheral blood, serum, organic coefficient, histopathologic examination weren't obvious changes after 1 month administrating aqueous extract of crude and processed drug in three dose. Serum indicators-urea nitrogen, cholesterol total, alkaline phosphatase manifestly were heightened and some animals'hepatic cells, nephric tubules and mucosa emerged differently damage at histomorphology by giving crude high dose after 2 months. Above organs emerged different damage in crude middle and high dose and processed high dose after 3 months and serum indicators- creatinine, urea nitrogen manifestly were increased, the coefficients of liver, kidney and gaster manifestly were heightened. However, the toxicity of identical dose processed product was lower than that of crude one. Aqueous extract and alcoholic extract of crude and processed Radix Aristolochice could obviously inhibite normal and revulsive hyperactive gastrointestinal motility by neostigmine of mice, relieve pain in mouse, stretching and heat stimulation models and inhibite dimethyl benzene-induc mouse, auricle inflammation. Pharmacodynamic action wasnt obvious difference in same dose of crude product and processed one.

CONCLUSIONAcute toxicity and chronic accumulated toxicity are stepped down after giving processed Radix Aristolochice, but pharmacodynamic effect wasn t lower. In pharmacodynamic effect, aqueous extract can't compare with alcoholic extract in same dose.
