[Objective] To observe the clinical effects of resvised wu pi decoction on mild and moderate ovarian hyperstimulation syndrome. [Method]To 30 of such cases ,take resvised wu pi decoction to strengthen spleen and tonify kidney, remove dampness and prevent miscarriage, observe patient chest dis-tress, abdominal distension and liquid intake and output volume of 24 hours etc.;Then estimate the clinical effect,and analyze one typical case.[Result]The marked effective rate was 60.00%, with total effective rate 96.67%. [Conclusion] The clinical application of resvised wu pi decoction treating mild and moderate OHSS by strengthening spleen and tonifying kidney,removing dampness and preventing miscarriage has excellent curative effect.

In recent years, much attention has been paid to arterial stiffness detection,but the relation between arterial stiffness and cerebrovascular disease has not been fully elucidated.This article reviews the detective methods of arterial stiffness and its relationship between the risk factors for cerebrovascular disease, ischemic stroke (including asymptomatic cerebral infarction) and cerebral hemorrhage.

Objective: To establish a method for the determination of related substances in dexmetomidine hy- drochloride gels,and investigate the compatibility of dexmedetomidine hydrochloride and excipients in the dexmetomi- dine hydrochloride gels. Methods: HPLC was performed on an octadecylsilane bonded silica gel column by a gradient elution with acetonitrile/0.008 mol/L NaH2PO4 solution as mobile phase. Flow rate was 1.0 ml/min. Column temperature was 30℃. Injection volume was 50 μl. Detection wavelength was 210 nm. According to the Basic Technical Guidelines for the Research of Chemical Drug Preparations,dexmetomidine hydrochloride was mixed with excipients in a certain propor- tion,and the mixtures were treated as test sample at the conditions of high temperature(60℃)and strong light(4500± 500)Lx irradiation. Sampling was performed on the 0,10th and 30th day of treatment,respectively. The appearance of the test samples was examined,and related substances in the samples were determined by the established HPLC method. Results: The established HPLC method showed a good specificity and durability,which could be used to accurately and effectively determine the changes of related substances. The appearance of the test samples the mixtures of dexmetomi- dine hydrochloride and excipients showed no changes in the full course of treatment at the tested conditions,and the re- lated substances were also not increased under the same conditions. Conclusion: The selected excipients(HPMC,pro- pylene glycol,methylparaben,sodium benzoate,and benzyl alcohol)all showed a good compatibility with dexmetomi- dine hydrochloride,and the tested mixture samples with the excipients and dexmetomidine hydrochloride were stable un- der the conditions of high temperature and strong light irradiation. These excipients could be used for the formulation screening for the dexmedetomidine hydrochloride gel development.

Human resources development in medical and health is of vital importance to medical and health sector reform and development as well as to medical and health existence and service improvement.Medical and health sector in China has made remarkable progress;however,facing the new requirements from economic and social development and people's new needs for medical health service because of their upaating health concepts and the new promotion by the development of biomedical science and technology,we still have some critical problems in medical and health personnel education.Therefore,the task of conducting careful analysis and exploring the solutions to these problems should be given sufficient attention and completed as soon as possible in the field of medical education.

Objective To investigate the effect of RNA interference plasmids of cysteine-rich 61(Cyr61) on hyperplasia of vascular smooth muscle cell (VSMC) in rats.Methods The plasmids containing the short hairpin RNA (shRNA) of Cyr61 were constructed.Expression of Cyr61 mRNA and protein were detected by reverse transcription polymerase chain reaction (RT-PCR) and Western blotting.The hyperplasia of VSMC was assessed by MTT.DNA synthesis was measured by incorporating ~3H-TDR.Plasmid construction was confirmed by DNA sequencing.Results PCyr61-shRNA transfection significantly decreased the level of mRNA and protein of Cyr61 in VSMC.The cell number,optical density and concentration of DNA in pCyr61-shRNA group were significant decreased(P

Objective To provide the anatomical data for single-nostril transsphenoidal microsurgery for pituitary adenoma.Methods Microanatomic structures were observed and measured in 20 cadaveric a- dults heads.Results(1)The diaphragmal opering was 5 mm or greater broad in 90%.The mean thick- ness of the diaphragma sellae was (0.18?0.08)mm.(2) A sphenoid sinus with complete pneumatization was named as all-sellae type,its percentage in all specimens was 85%,85% sphenoid sinus had middle sep- tum of which only 18.8% located in the medial sagital section.(3)The meant thickness of the sellar floor was (0.81?0.34) mm,70% of which were not more than 1 mm.Of the sellar floors,that the shape was flatness reach 15%.(4) The relationship between ICA and sphenoid sinus had two aspects,one was to be mutually apart (55%),the other was to communicate (45%),which formers carinae on the lateral wall of the sphe- noid sinus,espeially in the superior surface of posterior part.The relationship between optic nerve and sphe- noid sinus,one was to be mutually apart (27.5%),the other was to communicate (72.5% ),which formers carinae on the lateral wall of the sphenoid sinus,especially in the superior surface of anterior part.(5) Three main types of the intercavernous sinus were the anterior intercavernous sinus,present in 80%,the inferior in- tercavenous sinus (25%),and the posterior intercavenous sinus (15%).Conclusion The knowledge of the anatomy of the sellar region and sphenoid sinus is helpful to safe operation in the single-nostril transsphe- noidal approach for pituitary,adenoma microsurgery.

Objective To evaluate the value of SPECT/CT in differentiating malignancy from benign spinal disease. Methods Fifty-three patients with foci of abnormally increased uptake in the spine detected by 99Tcm-MDP planar whole body bone scan subsequently underwent bone SPECT/CT. The final diagnosis was determined by pathological examination or clinical follow-up ( ≥6 months), which was applied to calculate the diagnostic efficacy of bone SPECT/CT. Results A total of 25 patients were confirmed to have bone malignancy. The diagnostic sensitivity, specificity, accuracy, false positive rate, false negative rate, positive predictive value and negative predictive value for 99Tcm-MDP bone SPECT/CT were 96.00% (24/25), 96.43% (27/28), 96.23% (51/53), 3.57% ( 1/28), 4.00% ( 1/25), 96.00% (24/25) and 96.43% (27/28), respectively. Conclusion 99Tcm-MDP bone SPECT/CT imaging provides good clinical value for the differential diagnosis of spinal diseases.
