Objective To study the effect of CO 2 pneumoperitoneum and enteric disturbance on serum ?-endorphin (?-EP) in SD rats, in order to investigate their influence on peri-operative stress responses in SD rats. Methods A total of 120 SPF-grade male SD rats were randomly divided into four groups with 30 rats in each group. The four groups received CO 2 pneumoperitoneum (Group A), a 5 cm abdominal incision (Group B), a 5 cm abdominal incision with gastroenteric disturbance (Group C), and intraperitoneal anesthesia (Group D or Control Group), respectively. Concentrations of serum ?-EP of these groups were measured 10 min, 20 min, and 40 min after the beginning of surgery, respectively. Results Concentrations of serum ?-EP in the Group A 10 min, 20 min, and 40 min after the beginning of surgery were 274 7?66 6 pg/dl, 157 3?63 8 pg/dl, and 163 9?74 5 pg/dl, respectively, which were all extremely significantly higher than those in the Control Group ( P

Objective To analyse and conclude the MRI features of intracranial germ cell tumours so that to improve the diagnosis of this disease.Methods 15 cases of germ cell tumours verified by operation and pathology were reviewed and analyzed. All cases were undergone plain and contrast-enhanced MRI,the fat restrained sequence was performed if necessary. Results The location of tumors,six were in pineal region, six were in sellar region (germinoma, teratoma and choriocarcinoma in pineal and sellar region were all separately 3, 2 and 1), two were in basal ganglia (germinoma), and one was in right lateral ventricle (teratoma).Conclusion MRI is very valuable in the diagnosis and differential diagnosis of intracranial germ cell tumours.

OBJECTIVETo explore the molecular mechanisms of main active ingredients of Siwu decoction analogous formulae for treating primary dysmenorrhea of gynecology blood stasis syndrome by network pharmacology study, and to investigate the correlations between multi-compounds, multi targets and multi pathways.

METHODMajor active compounds from Siwu decoction analogous formulae, including ligustilide, butylidene phthalide, senkyunolide, ferulic acid, gallic acid, peoniflorin, jioglutin A, catalpol, transanethole, zingiberone, commiphoric acid, eugenol, isorhamnetin-3-O-neohesperidoside, wulingzhic acid, alpha-cyperone, cyperene, costunolide, costic acid, tetrahydropalmatine, protopine, amygdalin, 24-methylene cycloartanol, oleic acid, linoleic acid, 3-p-coumaroylquinic acid, hydroxysafflor yellow A, coptisine, berberine, jatrorrhizine, baicalein, baicalin, wogonin were collected to build component-protein networks based on PharmMapper database. The targets information access was used to construct and visualize components-targets-pathways network model using the kyoto encyclopedia of genes and genomes (KEGG) pathway database and Cytoscape software.

RESULT AND CONCLUSIONSerine threonine protein kinases play an important role in the process of cells. They were potential targets in the effect of Siwu decoction analogous formulae. The effect of main active ingredients involved 51 the pathway. Besides the same ones, Shaofu Zhuyu decoction had more effect on lipid metabolism, Xiangfu Siwu decoction on amino acid metabolism pathways, Taohong Siwu decoction on carbohydrate metabolism, while, Qinlian Siwu decoction on ErbB, VEGF signal transduction pathway. Siwu decoction and its derived formulae not only had common targets and pathways, but also had their own emphasis. This reflected the formulae effect mode of multi-ingredients, multi-targets and multi-pathways. It may provide clues to deeper study of molecular mechanism of Siwu decoction analogous formulae action.

Objective To design an auxiliary measurement device for anterior cruciate ligament injury in order to improve the accuracy of specialist examination and postoperative functional assessment.Methods The device consisted of a main frame and support pads,which was designed based on the principles of anatomopathology and mechanical mechanics.The frame was set above and paralleled to the tibia,and the measurement scale was put at the vertical direction of the frame.The support pads were fixed to the tibia and patella respectively to execute auxiliary measurement by providing opposite acting force.Results The success rate of preliminary diagnosis by the device was higher than that by traditional method.Conclusion The device gains advantages in convenience,practicality,low cost and etc,and is worthy promoting in the orthopedics department.

The heptadecatungstodiphosphate substituted by L a(Ⅲ) with the formula　α2-K7P2W17O61(La.OH2 ) (P2W 17La) was prepared by vacant refilling method. The anion of single substitu ted Dawson-type tungstophosphate salt was doped into the polypyrrole (PPY) film on a glassy carbon electrode (GC) by electrochemical method to prepare the chem ically modified electrode (P2W17La/PPY/GC). It maintains not only t he electrochemical activity and electrocatalytic property of P2W17L a, but also has good stability and sensitivity. In 0.50 mol/L HCl solution, th e first cathodic peak of P2W17La doping in polypyrrole film can cat alyze well the electroreduction of nitrite. The catalytic current was proporti onal to the concentration of nitrite between 6.0×10-5 and 1.0×10-2 　mol/L.

Objective To develop a cryogenic gripper for soft tissues used in tensile test for secure fixation of soft tissues without damages.Methods Based on the principle of coolant evaporator,we reconstructed copper pipes in novel architecture for fixing the soft tissues.Results This cryogenic gripper could firmly grip wet nylon thread of 3 mm in diameter and its holding force was(499.14?1.05)N and its temperature could be kept at(-20?1)℃.Conclusion The function of this gripper developed by coolant cryogenic technology is satisfactory and reliable,and its continuance is not concerned with time.

Objective To observe the effects of the Dachaihu decoction on intra-abdominal pressure in severe acute pancreatitis. Methods 70 patients with SAP from China-Japan Friendship Hospital were randomly divided into two groups. 35 patients in a conventional treatment group were treated with conventional treatment of severe acute pancreatitis, and 35 patients in a Dachaihu decoction treatment group were treated with the decoction through nasogastric tube based on conventional treatment. The changes of intra-abdominal pressure and the morbidity of IAH and ACS in both groups were observed in acute stage. Results The intra-abdominal pressure in both groups increased. But the pressure in the Dachaihu decoction treatment group (13.31 ± 4.42 mmHg, 13.02 ± 5.23 mmHg, 12.35 ± 3.34 mmHg, 11.26 ± 4.46 mmHg, 9.89 ± 3.44 mmHg) was lower than the conventional treatment group (16.89 ± 5.71 mmHg, 17.52 ± 3.37 mmHg, 16.21 ± 2.15 mmHg, 14.57 ± 5.56 mmHg, 12.11 ± 1.28 mmHg) from the third day on (P<0.05). And the morbidity of intra-abdominal hypertension and abdominal compartment syndrome in the Dachaihu decoction treatment group were lower than the conventional treatment group in the whole acut stage (40%vs. 8.75%).The differences between two groups were statistically significant (P<0.05). Conclusion The Dachaihu decoction may significantly reduce the intra-abdominal pressure and the morbidity of intra-abdominal hypertension and abdominal compartment syndrome among patients with severe acute pancreatitis.

Objective:To observe the clinical efficacy and safety of compound Bletilla Striata cream in the treatment of patients with second degree hand rhagadia. Methods: Totally 146 patients with second degree hand rhagadia were randomly divided into the treatment group and the control group with 73 cases in each. The treatment group was treated with compound Bletilla Striata cream, while the control group was treated with urea ointment. The treatment course was 10 days. The time of paln disappearance, keratoder-ma softening and rhagadia healing were compared between the two groups, and the efficacy and adverse drug reactions of the two groups were also observed and compared. Results:After the first treatment course, the curative rate of the treatment group was 94. 5%, which was higher than that of the control group (82. 2%) with statistical significance (P<0. 05). The total effective rate of the two groups was both 100% without statistical significance (P>0. 05). The time of keratoderma softening and rhagadia healing in the treatment group was significant shorter than that in the control group (P<0. 05), while the time of paln disappearance showed no significant difference between the two groups(P>0. 05). Conclusion: Compound Bletilla Striata cream in the treatment of second degree hand rhagadia is effective and safe, which shows good prospect for clinical application.
