1.Study on volume-pressure relationship during the progression of an acute intracranial space-occupying lesion in dogs
Journal of Third Military Medical University 1988;0(05):-
An inflatable liquid epidural balloon was used to simulate an intracranial space-occupying lesion.Two groups of dogs with 8 in each were employed.Under different conditions and time intervals,intracranial pressure(ICP)was continuously recorded,and pressure-volume index(PVI),volume-pressure response(VPR),and cerebrospinal fluid pulse pressure(CSFPP)were measured silmutaneously.It was found that PVI was in significant negative linear correlation with ICP,while VPR and CSFPP in significant positive linear correlation with IVP(P
2.Presentation and DSP Implementation of Wavelet Zero-cross Stimulation Strategy for Cochlear Implants
Chinese Medical Equipment Journal 2003;0(11):-
Objective To introduce the wavelet zero -cross stimulation algorithm and based on which to design and implement the cochlear implants. Methods Through DSP and ICETEK-VC5416, the WZS speech coding strategy was simulated, and also the presented WZS strategy was compared to CIS strategy by hardware implementation and computer simulation. Results The processed audio signals, output from eight channels, were synthesized and played through loudhailer and could be heard with high fidelity. Conclusion The wavelet zero-cross stimulation(WZS) strategy, which generates stimulating pulsatile series at zero-cross points in the domain of wavelet transform, can keep the temporal correlation and coherence of speech remained in stimulating pulsatile series and reflects the characteristic of temporal coding for cochlea.

Chinese Journal of Health Management 2008;2(3):143-145
Objective To investigation the relationship between health management and prognosis of chronic prostatitis. Methods Three hundied and forty-six cases of chronic prostatitis were divided into two groups. The control group treatment was local washing and medicine for three months. The experiment group treatment was local washing, medicine, and health management for three months. NIH-CPSI was used for the results. Results There was no significant different between the experimental group(165 cases)and the control group(154 cases)before treatment in NIH-CPSI. The effective rate of the the experimental group was 88.5%, and that of the control group was 64.9% after treatment. It is effective for cure and the prognosis of the experiment was better than the control (P<0.05). Conclusion It is suggested that it is more effective for the prognosis of chronic prostatitis after the intervention of health management.

Objective:To study the effects of LeFort I osteotomy in the treatment of old maxillary fracture.Methods:30 patients with old maxillary fracture were treated with LeFort I osteotomy,the rehabilitation of occluding relation and masticatory function were observed after operation.Results:28 patients had well-pleasing occluding relation and masticatory function; 2 patients dissatisfied with their masticatory function, because of unbalance of nerve-muscle after their occlusal plane were rebuilt.Conclusion:LeFort I osteotomy can be a method in the treatment of old maxillary fracture.

To evaluate the influence of different brands of syringes on performance parameters and application quality of syringe pump, we carried out matching experiment of infusion/syringe pump analyzer Rigel Multi-Flo, made by ALK Co. in Sweden, for 3 different types of syringes to measure the flow rate, occlusion alarm pressure, occlusion time and bolus volume of 26 syringe pumps. Data of quality control were analyzed with statistical method. The results demonstrated that there were significant differences in the flow rate, occlusion alarm pressure, occlusion time and bolus volume (P<0. 01) between those of common syringes and original syringes. This study points out that the health care providers should select compatible syringes for syringe pumps, which provides evidence and guidance to assure the reasonable and safe application of syringe pumps in clinical practice.

Objective To compare the clinical efficacy between laparoscopy and open cholecystectomy for patients of acute calculous cholecystitis. Methods Fifty patients of acute cholecystitis from February 2014 to February 2017 were divided into control group treated with open cholecystectomy and observation group with laparoscopic cholecystectomy;a retrospective analysis was conducted to compare time of resuming peristaltic sound ,postoperative 24h VAS score and hospitalization time. Results There were shorter time of resuming peristaltic sound,higher postoperative 24 h VAS score and shorter hospitalization time in observation group when compared with those in control group (P < 0.05). Conclusions For patients of acute calculous cholecystitis , laparoscopic cholecystectomy,is conducive to shortening patient′s recovery time,alleviating patients′ pain signifi-cantly and decreasing the incidence of complication.

laparoscopic technology has been widely used in the fields of surgery such as general surgery etc. It has several advantages,such as directly showing abdominal organs,demonstrating operation procedure and being easy to make and spread operation video material. Laparoscopic system should be used for intern teaching in general surgery department to improve their learning and performance.

Objective To promote rational drug use and assure the drug use in an effective and safe way by developing the monitoring role of clinical pharmacists in the adverse drug reaction .Methods The common reasons for adverse drug reaction were an-alyzed.The clinical pharmacists took advantage of their professional knowledge to deal with adverse drug reactions and reinforce the monitoring of the drug treatment.Results The clinical drug safety was ensured by reducing the adverse drug reaction incidence rate. Conclusion Pharmacy information exchange should be enhanced and the professional knowledge of clinical medical staff should be broadened to promote clinical rational drug use.

The CD19-targeted chimeric antigen receptor (CAR) T-cell treatment has achieved clinical success in treating B-cell lineage hematopoietic malignancies. This accomplishment involved the precise and efficient elimination of tumor cells by tumor-associated an-tigen-redirected immune cells. As a result, the reinitiation of several CAR T-cell (CART) based clinical trials in solid tumors was promot-ed. However, developing a feasible and efficient CAR T based therapeutic modality for solid tumors is urgently needed given the differ-ential properties between liquid and solid tumors. In this review, we discuss the advances in the management of cytotherapeutic mo-dality for solid tumors. The aspects considered include toxicity management, target selection, and primer or conditioning treatment.

Objective To compare the analgesic and side effects of tramadol, buprenorphine and morphine in equipotent dosage in patient-controlled intravenous analgesia (PCIA). Methods 53 patients (ASA I-II) scheduled for upper abdominal surgery were randomly allocated to receive 10mg/ml tramadol (group T) or 0.03mg/ml buprenorphine (group B) or 1mg/ml morphine (group M) plus 0.1mg/ml droperidol. Baxter APII PCA pump was used to administer the different analgesic according to the model of LCP, with the amount of loading dose, continuous infusion and bolus of 2.5ml, 0.5ml/h, 1ml respectively. At 4, 8, 16 and 24h postoperatively, pain scores in VAS, comfort scale in BCS, sedation scores with Ramsay score, and the incidences of nausea, vomiting, pruritus, respiratory depression were assessed. Drug consumption in the first 24h and the D/D ratio (demand/deliver) were also recorded. Results VAS and BCS scores showed no significant difference among the 3 groups, but drug consumption within the first 24h and the D/D ratio in group T were higher than those in other 2 groups (P0.05). 8 patients in group T, 5 in group B and 4 in group M suffered from nausea; 1 patient in group T, 2 in group B and 3 in group M complained of pruritus. No respiratory depression was observed in all cases. Conclusion Tramadol and buprenorphine can be safely used as PCIA in patients undergoing upper abdominal surgery, but they are not superior to morphine.
