Described in this paper are the strategies for rational storage and sharing of postgraduate dissertations in medical colleges and universities with the development of dissertations and its related problems in Library of Capital Medical University as an example.

After the links of lectures on use of information resources in Library Capital Medical University were de-scribed, the implementation steps of lectures and our experiences were summarized, and the demand of readers for such lectures was analyzed with suggestions proposed for the position and popularization, Website platform building and brand construction of lectures in order to promote such lectures, help readers to effectively use the databases in libraries and expand the influencing power of libraries.

Objective To observe the preliminary curative effect of transrectal ultrasound-guided lauromacrogol injection for treating benign prostate hyperplasia in elderly patients.Methods Forty-two patients with benign prostate hyperplasia combined with lower urinary tract symptonms received transrectal ultrasound-guided lauromacrogol injection.Then they were followed up after 3,6,12 months respectively. Prostate volume changes before and after treatment,international prostate symptom score(IPSS),postvoid residual volume (PRV ),maximum urinary flow rate (Qmax ) and features of contrast-enhanced ultrasonography before and after treatment were observed.Complications were analyzed.Results Before treatment,prostate volume,IPSS,PVR of patients were (57.3±1 7.7)ml,(28.3 ±5.2)points,(143.8±82.5) ml respectively,12 months after treatment,they reduced to (44.8 ±6.1 )ml,(8.8 ± 1 .4)points,(28.9 ±9.5 ) ml,there were statistical diffrences between before and after treatment(P <0.05 ).Qmax increased from (5.9±3.2)ml/s to (14.9 ±3.1 )ml/s (P <0.05).Contrast-enhanced ultrasonography showed filling defect sign in prostatic inner gland.No serve complications occurred.Conclusions Transrectal ultrasound-guided lauromacrogol injection for treating benign prostate hyperplasia has the characteristics of minimally invasive,safe,effective and economical.It applies to elderly patients who are unable or unwilling to have surgery.

Objective To observe the curative effect of the microwave ablation (MWA) therapy for hepatocellular carcinoma (HCC) with arterio-venous fistula (AVF) in patients with intervention and operative contraindication,and to observe the clinical effect.Methods MWA therapy was offered to 24 patients with HCC combined with AVF accompanied with intervention and operative contraindication.The complete ablation rates,volume changes of tumors before and after treatment were observed.Color Doppler ultrasonography was performed to evaluate the peak flow rate and resistance index(RI)of AVF,width and flow rate change of portal vein.The lifetime of patients were also observed.Results All patients were treated with double needle therapy.The first time complete ablation was 75.0％ (18/24).Then they were followed up after 6 months.The volume of tumors was (72.9 ± 23.8)cm3 and (57.6 ± 19.8)cm3 (P ＜0.01) before and after treatment.The AVF disappeared in 20 cases,while flow rates of fistula orifice decreases obviously in the rest of them.The widths of portal veins decreased from (1.4 ± 0.9)cm to (1.3 ± 0.1)cm,while the flow rate of that increased from (7.5 ± 3.9)cm/s to (20.1 ± 2.9)cm/s.The survival rates of patients for one,two and three years were 66.6 ％ (16/24),37.5 ％ (9/24) and 20.8 ％ (5/24),respectively.Conclusions Most AVF disappeared after MWA therapy in HCC combined with AVF.The therapy can relieve portal hypertension symptom effectively and improve survival time and life quality of patients.So it is a good treatment for patients with HCC combined with AVF while with intervention and operative contraindication.

It is the direct and main cause of trigeminal neuralgia that responsible vessel compresses the root entry zone of sensory root of trigeminal nerve.Microvascular decompression is an effective way in treating trigeminal neuralgia with higher cure and lower recurrence,which can eradicate the common cause of trigeminal neuralgia and maintain the normal function of trigeminal nerve;At the same time it is an safe way with lower risk on the basis of skilled microsurgical technique.So it is an optimal approach to treat trigeminal neuralgia.

The treatment of chronic pain needs multidisciplinary management.Neurosurgical procedures hold an important role.With advancement in stereotactics,microsurgical and electrophysiological techniques,neurosurgical treatment becomes microinvasive,safer and popular.Neurosurgical procedures include anatomic,neuroaugmentative and neuroablative therapies.The procedure should be chosen individually.The pain characters,primary disorders,quality of life and survival time of the patient should be considered.A successful management must be well-indicated.

OBJECTIVE:To observe the curative effect of Qingyan lifei mixture on cough with lung heat.METHODS:190 patients with cough with lung heat were randomly divided into two groups:104 cases in treatment group were assigned to receive Qingyan lifei mixtures 100 mL?time-1 bid,and 86 in control group to receive Qingfei yihuo tablets(4 tablets?time-1 bid).The course of treatment was 10 days for both groups.RESULTS:The total effective rate was 89.42% in treatment group versus 75.58% in control group,and the difference between the two groups was significant(P

By the method of chemiluminescence, it was showed that BW-755C strongly inhibited the generation of active oxygen in PMNs stimulated by f-MLP, A23187 or opsonized zymosan A, while the inhibitory effect of indomethacin was quite weaker, Nifidipine, diltiazem and verapamil inhibited the generation of active oxygen in PMNs stimulated by A23187 at low concentration, but they did not block intracel-lular calcium ion increase stimulated by A23187. PGE1 was shown in to be a selective inhibitor of f-MLP-induced active oxygen production PMNs.

Sixty-four patients with solitary pulmonary nodules were included in this study. The diameter of pulmonary nodules was equal or less than 3.0 cm and no contact with the adjacent pleura. They were divided into study group( with acuductor locating method)and conventional group (with conventional method). The results showed that the one-time success rates were 97％ (31/32)in study group and 72％(23/32) in conventional group, the diagnostic accuracy were 94％ ( 30/32 ) and 88 ％ ( 28/32 ), respectively,while the successful puncture time were( 13. 5 ±4. 9)min and( 18. 7 ±5. 7) min, respectively. In study group,the complication rate was 9％ (3/32), while 28％ ( 9/32 ) in conventional group. There were statistical differences between the two groups. CT-guided aspriation biopsy for solitary pulmonary nodules with self-made acuductor can obviously improve one-time success rate and reduce the complication rate and operative time.

Objective To assess the value of muhichannel epidural somatosensory evoked potential (SEP) in cortical mapping of primary sensorimotor areas for electrode implantation of motor cortex electrical stimulation.Methods Intraoperative multichannel epidural SEP was recorded in 13 patients with intractable neuropathic pain.SEP mapping was used for determining the location of sensorimotor areas.Results The typical phase reversals of N20 and P20 were recorded and the location of the central sulcus and the primary sensorimotor area were accurately determined in 11 patients.The location of the primary sensorimotor failed to be determined in the other 2 patients because of the atypical SEP.Conclusion The intraoperative muhichannel epidural SEP is reliable in the cortical mapping.
