A success in reconstruction of the hematopoietic function of marrow in a case of malignant lymphoma attained by autologous peripheral blood stem cell transplantation after the ultra-high dose chemoradiotherapy was reported. The platelet count of patient was increased to over 20 ? 109/L at the eighth day after PBSC transplantation and was recovered to over 50?109/L at the tenth day after PBSC transplantation. The white blood cell count was increased to over 0. 5?109/ L at the ninth day after PBSC transplantation. The pelvic CT-graphy showed reduction in size of the tumor. And then the patient was outhospitalized due to remission,having been surviving for more than 6 months with routine follow-up. It was suggested that the autologous peripheral blood stem cell transplantation could be a safe and effective suplement therapy for radical cure of malignant tumor.

Objective To investigate the correlation between the severity of subcortical ischemic lesions and vascular cognitive impairment in encephalorrhagia patients. Methods One hundred and twenty-four encephalorrhagia patients were enrolled into two groups, the normal cognition group (60 cases, without cognitive impairment) and the cognitive impairment group (64 cases, with vascular cognitive impairment). Parameters of the lesion diameters, various lesion locations, white matter lesions severity and NIHSS scale score, modified Bathel index score were compared between these two groups. The correlations between the above indexes and the vascular cognitive impairment degree were analyzed by Logistic regression proceduress. Results Compared to the normal cognition group, the indexes of lesion number of frontal area and basal ganglia, lesion diameters, white-matter severity and NIHSS scale score of cognitive impairment group were higher (P<0.05, respectively), and the modified Bathel index score was lower (P<0.05), but the lesion number in temporal, parieto-occipital and infratentorial area were not changed (P>0.05, respectively) in the cognitive impairment group. Result of Logistic regression analysis showed a positive correlation between the severity of white-matter and the degree of vascular cognitive impairment (OR =4.705, P=0.009). Conclusion The severity of white-matter can effectively assess the degree of vascular cognitive impairment of encephalorrhagia patients.

Objective To review and analyze the application of retroperitoneal laparoscopy and open surgery in ureteropelvic junction obstruction, sum up clinical expeirence, and improve the skills of retropeirtoneal laparoscopic surgery. Methods Retroperitoneal laparoscopic surgery was carired out in 22 csaes of ureteropelvic junction obstruction(retroperitoneal laparoscopy group). Open surgery was carried out in 21 cases(Open surgery group). The two groups were compared in operation time, blood loss postoperative discharge time and postoperative hospital stay respectively. Results Ureteropelvic junction obstruction group was significantly less than open surgery group in intraoperative bleeding time,postoperative bleeding time and average length of stay. Operation time in ureteropelvic junction obstruction group was slightly longer than that in open surgery group [(32.0 ± 10.0) ml vs (70.0 ± 11.9) ml, (31.0 ±5.7)h vs(52.0 ±6.9)h,(7.0 ± 1.6) d vs(14.0 ± 1.4) d, (113.0 ±7.6) min vs(72.0 ± 6.8) min] (t = 7.06,8. 14,11.37,11.36, all P ＜ 0.05). Conclusions Retroperitoneal laparoscopic technology was in the treatment of ureteropelvic junction obstruction for its direct way, had non interference and pollution to laparoscopic internal organs,less damage,less pain, rapid recovery and short hospitla stay. With on going training and constantly updating technical skills and equipments, retroperitoneal laparoscopic technology will shotren the operation time, and will substitute open surgery.

Objective:To investigate the effects of medroxyprogesterone acetate(MPA) on the proliferation and apoptosis of human colorectal cancer cells.Methods: Human colorectal cancer cell line LS174T was treated with different concentrations of MPA(12.5,25,50 and 100 ?mol/L) for 120 h.The inhibitory effect of MPA was measured with MTT method;the cell cycle,cell apoptosis,and cell surface Fas expression were analyzed with flow cytometry.Results: MPA had significant inhibitory effect on the growth of LS174T human colon cancer cells.Cell growth was found to be arrested in G_(1) phase and cells in S phase and G_(2)/M phase were decreased.The natural apoptosis rate and the apoptosis rates at MPA 12.5 and 25 ?mol/L were 4.8%,15.1%and 25.6%,respectively.Cell surface Fas expression in cancer cells increased after treated with MPA.Conclusion: MPA has significant inhibitory effect on the growth of human colon cancer cells,which may be related to Fas expression upregulation on cancer cell surface and G_(1) phase arrest.

Objective To explore a new way of treating refractory residual gallstones by endoscopy. Methods Choledochfiberscope(CHF) combined with air pressure ballistic lithoclast(APBL) under ureterscopy were used on 28 cases of large or impacted residual gallstones.

Conclusions This procedure is a safe, effective, simplicity, less complication and no heat injury methods. It is proved to be a new way of treating refractory residual gallstones, especially for large or impacted lithiasis. It is worthy for clinical application widely in the future.

Objective To apply early comprehensive rescue including embolism and microsurgery for trea- ting acute ruptured intracranial aneurysm in order to lower mortality and disability.Methods 120 patients with rup- tured intracranial aneurysm were treated by early comprehensive rescue.An cases were given support treatment,e- mergency rescue and DSA after hospitalization.Embolism and microsurgery were done within 72 hours and releasing bleeding CSF were done after surgery to prevent complications.Results Good recovery was over 80%(excellent in 95 ases,light disability in 18 cases,heavy disability in 4cases,and death in 3 cases).2 cases relapsed during hospi- talization.5 cases were coma induced by serious cerebral vesospasm.Conclusion Early comprehensive treatment including embolism and microsurgery complication prevention may reduce rebleeding,serious vasospasm and hydro- cephalus,1ower mortality and improve prognosis.

Objective To analyze the feasibility of theone-cardmode for division-level cadres hospitalized at military hospitals, and to provide reference for application of this mode to cadres under the regimental level who are hospitalized at military hospitals.Methods A 4-month pilot project was carried out among division-level cadres in Lanzhou, Jinan, Nanjing and Chengdu.Data collection and statistical analysis were conducted through the monitoring platform established in the administrative section.Results Division-level cadres outside the system mostly chose division-level hospitals.Patients thended to be hospitalized at nearby or high-quality hospitals mainly due to cardiovascular and cerebrovascular diseases and malignant tumor.Accommodation was not difficult.Conclusion The one-cardmode is feasible at military hospitals for division-level cadres, but the current system of initial diagnosis at basic medical institutions should be maintained.An information sharing platform of electronic medical records should be built to implement inter-hospital linking and sharing of diagnosis and treatment information.A budget subsidy mechanism should be established to normalize hospitalization.

Objective To explore the effect of Jin's three-needle therapy, as an assistant treatment, in improving the intelligence of children with mental retardation (MR).Method Seventy-six MR patients were divided into a control group and an observationgroup, 38 cases in each group.The control group was treated with rehabilitation, while the observation group with JIN's three needle therapy plus the rehabilitation training.Prof. JIN Rui's 10-item observation index was adopted to evaluate the memory ofthe patients before and after the treatment; Gesell Developmental Schedule (GDS) was used to measure the intelligence before and after the treatment. The clinical efficacies in the two groups were statistically analyzed.Result After the treatment, Prof.JIN Rui's 10-item index scores dropped obviously and the GDS scores increased significantly in both groups, while the decrease and increase of scores in the observation group were more significant than those in the control group (P<0.05). The total effective rate was 94.7% in the observation group, significantly higher than 71.1% in the control group (P<0.05).Conclusion As an assistant treatment, JIN's three-needle therapy can help rehabilitation training to improve the intelligence of MR patients.
