Objective To evaluate cerebral autoregulation in cerebral vascular disease using transeranial Doppler(TCD)-CO_2 test and head-upright tilt test(HUTT).Methods Thirty-two patients with occlusive cerebral vascular disease (group A),28 cerebral infarction patients without stenosis (group B), and 26 controls were included.Cerebrovascular reactivity was calculated in terms of the breath-holding index (BHI) and vascular motor reactivity (VMR) by TCD-CO_2 test.Changes of cerebral blood flow velocity (CBFV),blood pressure (BP) and heart rate (HR) were detected during HUTT to assess the cerebral pressure-autoregulation.Results Compared with controls,VMR decreased in group A and B,being 0.18?0.02,0.26?0.04 respectively,and so did BHI,being 0.76?0.15,1.05?0.15 respectively with significance(P

Objective To assess the efficacy of functional magnetic stimulation (FMS) in treatment of neurogenic dysfunction of bladder and urethra in patients with spinal cord injury. Methods A total of 12 patients accepted FMS to the sacral nerves at S 3 and bladder area. The study variables included urodynamic parameters,the quality of life and international lower urinary tract syndrome (LUTS)symptoms. Results There were significant improvements in 10 patients with respect to the number of voiding,volume voided and degree of frequency,urgency and incontinence. Only 2 patients were failed to make any progress. Conclusion FMS is an effective,safe therapy for the spinal cord injury patients complicated with neurogenic dysfunction of bladder and urethra and improve the patients' quality of life.

Objective To evaluate the effectiveness of "dispersing lung-qi and relieving asthma, warming Yang to induce diuresis" method on CPHD patients during acute period with peripheral edema and observe the effect on ADH. Methods The CPHD patients during acute period with peripheral edema were randomly divided into treatment group and control group. The treatment group received Chinese medicine adding to regular western medicine, the principle is dispersing lung-qi and relieving asthma, resolving phlegm to stop coughing, warming Yang to induce diuresis. The control group received placebo adding to regular western medicine. Both of the groups were treated for 14 days. The effect observed indexes were as follows:general curative effect, integral of main symptoms of TCM, integral of western medical signs, serum electrolyte, etc. Mechanism index was about ADH. Results The treatment group had better effects than the control group on the general curative effect, reducing integral of symptoms and signs, rectifying electrolyte and acid-alkaline-balance disturbances, etc. The safety analysis of two groups had no significant abnormality. Meanwhile, the treatment group had more superiority than the control group on reducing serum ADH. Conclusion The comprehensive treatment of traditional Chinese and western medicine probably has more advantage in increasing the general effect, improving symptoms and signs, rectifying electrolyte and acid-alkaline-balance disturbances, etc. This therapeutic method can restrain secretion of ADH. It indicates that restraining secretion of ADH maybe part of the mechanism of using "dispersing lung-qi and relieving asthma, warming Yang to induce diuresis" method to treat CPHD patient during acute period with peripheral edema.

Objective To observe the clinical therapeutic effects of Chushihuayu Decoction on the level of serum uric acid and triglycerides in patients with hyperuricemia and hypertriglyceridemia. Methods Fifty cases of hyperuricemia and hypertriglyceridemia with damp-heat syndrome (DHS) were randomly divided into Chushihuayu Decoction-treated group and benzbromarone-treated group. The course of the treatment was 30 days. The serum levels of uric acid and triglycerides before and after treatment were analyzed. Results The serum level of uric acid was reduced in Chushihuayu Decoction-treated group. The DHS was relieved in Chushihuayu Decoction-treated group. The serum level of triglycerides was lowered in Chushihuayu Decoction-treated group. Conclusion Chushihuayu Decoction can decrease serum uric acid and triglycerides, and improve the DHS.

Objectives To express human TFPI-2 gene in E.coli and get the recombinant protein;to investigate the recombinant activities of antiplasmin and antitumor.Methods (1) Encoding region of mature protein of human TFPI-2 was amplified by PCR.The 645 bp PCR product was cloned into expression vector pET28a and transformed into BL21 strain to get expression.(2)Identifying the DNA segment of TFPI-2 with enzyme digestion and colony PCR and the TFPI-2 fusion protein with western blot respectively.(3)To establish the kinetics assay for detecting the TFPI-2 and test it′s inhibiting plasmin activities.(4)To assess ovarian tumor cell migratory and invasive behaviors with the Boyden chamber in vitro.Results (1)Expression plasmid of recombinant TFPI-2 was constructed and high-level expression of TFPI-2 was produced as fusion protein. (2) The TFPI-2 fusion protein was identified by western blot. (3) Antiplasmin activity of the TFPI-2 was confirmed in the fluid and on the cell surface. (4) In invasion assay, the number of the A2780 and A2780-TFPI-2 groups transferred the Matriged matrix-coated PVPF membrane was obvious decreased compared with that of A2780 group(P0.05).Conclusion (1) Prokaryotic expression of TFPI-2 gene was got, which can provide the rich experimental material for investigating the role of TFPI-2 in relative fields; (2)Recombinant TFPI-2 has antiplasmin activity, which provides the experiment basis for investigating the role of recombinant TFPI-2 in human ovarian tumor migration and invasion in vitro; (3) The recombinant TFPI-2 inhibits the invasive ability of human ovarian tumor cells in vitro, but has no effect on the migration, which may provide a target basis for treating human ovarian tumor with TFPI-2 protein therapy.

Objective To explore the diagnostic value of CT-guided percutaneous lung biopsy for pulmonary solid lesions.Methods CT-guided percutaneous lung biopsy was performed in 97 cases of pulmonary solid lesions. The lesions were 2~10 cm (mean, 4.2 cm) in diameter, and the distance to the pleura was 0~8 cm (mean, 3.4 cm). Results Confirmative diagnoses were achieved in 73 cases of lung cancer and 21 cases of benign lesions (inflammation, tuberculosis, or sarcoidosis). The diagnostic rate was 96.9% (94/97). The biopsy could not indicate the accurate diagnosis in 3 cases, 2 of which were identified as having squamous cell carcinoma by operation, and 1 of which was followed for 2 years with no changes. Postoperative complications included 8 cases of pneumothorax, 2 cases of hemothorax, and 2 cases of emptysis. Conclusions CT-guided percutaneous lung biopsy is safe and offers a high diagnostic rate, especially suitable for lesions near the pleura.
